        This LEASE (the "Lease") is made and entered into as of this 3rd day of
July,  1996,  by and between 1155 Market Partners,  a California general
partnership  (the   "Landlord")  and Genesys Telecommunications  Laboratories,
Inc. (the "Tenant").


                                  WITNESSETH:
                                  -----------

        1.  Premises.  The Landlord, in reliance upon and in consideration of
            --------
the rents hereinafter reserved and of the covenants and agreements hereinafter
mentioned to be kept and performed by the Tenant, does by these presents lease
and let unto the Tenant, and the Tenant does hereby hire and take from the
Landlord, approximately 36,198 square feet on the 9 , 10 , and 11th floors as
outlined in red on Exhibit A attached hereto and made a part hereof (the
"Premises" or "Leased Premises") of a certain building located at 1155 Market
Street in the city and County of San Francisco, State of California (the
"Building") located on the real property more particularly described in Exhibit
B attached hereto and made a part hereof (the "Property").   On or before the
Commencement Date with respect to each floor, Landlord shall have each such
floor measured in accordance with BOMA standards.  If any measurement discloses
that the number of rentable square feet in the Premises is not, in fact, 36,198
square feet, then this Lease shall be amended to reflect the true square footage
of the space with appropriate adjustments to Minimum Rent and the definition of
Tenant's Share.

        2.  Use of Premises.   The Premises shall be used for offices and
            ---------------
training and for no other use or purpose without the prior written consent of
Landlord.

        3.  Initial Term.   (A) This Lease shall commence and the payment of
            ------------
rent shall start: (i) with respect to the tenth floor, on August  1, 1996, (the
"Tenth Floor Commencement Date"),  (ii) with respect to the eleventh floor, on
September 1, 1996 ("Eleventh Floor Commencement Date") and (iii) with respect to
the ninth floor, the later of December 1, 1996 or sixty (60) days after the
Landlord obtains possession of the ninth floor from the existing tenant ("Ninth
Floor Commencement Date").  The term of this lease shall expire on September 30,
2000 (the "Expiration Date").

          (B) The Rent Commencement Date for the 9th and 11th floors shall not
occur until the work has been substantially completed.  The term "substantially
complete" shall mean the date that all of the following shall have occurred: (a)
Tenant' s architect shall have certified to Landlord and Tenant that the Tenant
Improvements are substantially complete in accordance with the final plans and
specifications therefor, and (b) there remains no incomplete or defective item
of Tenant Improvements that would adversely affect or interfere with Tenant's
occupancy of the floor in question for Tenant's intended use thereof.  Landlord
promises to use diligent good faith efforts to substantially complete the
improvements required by Tenant to be constructed on the tenth floor by August
1, 1996.  Tenant shall submit to Landlord the architectural drawings for the
work on the 11th floor on or before July 24, 1996 and for the 9th floor on or
before September 17, 1996.  If for any reason the Tenant does not deliver its
complete architectural plans on or before the above-referenced date, then rent
payment shall commence on the dates set forth in paragraph 3(A)hereof regardless
of when the work is completed.

        4.  Possession.  Possession of the Premises shall be delivered to the
            ----------
Tenant as soon as  the Tenant Improvement Work ordered by the Tenant is
substantially completed. If the Landlord for any reason does not use its best
efforts to complete the work timely and properly, then the Tenant shall not pay
rent until possession of the Premises is actually turned over to the Tenant.

        Landlord warrants and represents that as of the Commencement Date

                                       1

 
for each floor, such floor shall be broom clean, in good condition and repair
and the electrical, mechanical, HVAC, plumbing, elevator, fire safety, security
and other systems serving such floor will be in good condition and repair. If a
non-compliance with said warranty exists as of the applicable Commencement Date,
Landlord shall, promptly after receipt of notice from Tenant (even if such
notice is received after the applicable Commencement Date, but in no event more
than 90 days after the Commencement Date), rectify the same at Landlord' 5
expense.

          As of the applicable Commencement Date, each floor of the Premises and
the Building shall comply with all underwriter' 5 requirements and all rules,
regulations, statutes, ordinances, laws and building codes applicable thereto.
None of the provisions of the preceding sentence shall affect the Commencement
Date for the payment of rent as set forth above.

        5.1 Minimum Rent. Tenant agrees to pay to Landlord, without demand, a
            ------------
minimum monthly rental (the "Minimum Rent") for the Premises, for each and every
month, payable in advance the first day of each month, based on the following
schedule:

                     08/1/96   -  08/31/96   $20,110.00
                     09/1/96   -  11/30/96   $40,220.00
                     12/1/96   -  07/31/98   $60,330.00
                     08/1/98   -  07/31/00   $63,346.50

Should for any reason as set forth herein, the commencement date for a floor not
be the first day of the month, the rent for that month shall be pro-rated for
the number of days in the shortened month. Notwithstanding the above, Tenant
shall have a ten (10) day grace period from the 1st of the month to the 10th of
the month to pay rent to Landlord three times in each twelve-month period
beginning on the Tenth Floor Commencement Date.

        (a) As Additional Rent, Tenant shall pay to Landlord at the times
hereinafter  set  forth,  an  amount  equal  to  (a)  Tenant's  Share  specified
hereinbelow of any increase in "operating expenses"  (defined below in this
paragraph 5.2) paid or incurred by Landlord on account of the operation or
maintenance of the Building above such operating expenses paid or incurred by
Landlord during the Base Year specified hereinbelow, and (b) Tenant's share of
any increase in "direct taxes" (defined below in this paragraph 5.2) paid or
incurred by Landlord in any calendar year in excess of those paid or incurred in
the Base Year specified hereinbelow.   Notwithstanding the foregoing to the
contrary,  Tenant shall not be responsible for any increase in "operating"
expenses  or increase in "direct taxes" attributable to any period of time
commencing on the Tenth Floor Commencement Date and ending on the first
anniversary of the Tenth Floor Commencement Date.  If at any time during the
term of the Lease, less than ninety-five percent (95%) of the total leasable
area of the Building is occupied, the operating expenses and direct taxes shall
be adjusted by Landlord to reasonably approximate the operating expenses and
direct taxes which would have been incurred if the Building had been at least
ninety-five percent (95%) occupied.

        At or after the commencement of any calendar year subsequent to the Base
Year Landlord may, but shall not be required to, notify Tenant of Landlord's
estimate of the amount of any increase in operating expenses for such calendar
year over operating expenses for the Base Year, the amount of any increase in
direct taxes over those paid or incurred in the Base Year and of the amount of
such estimated increases payable by Tenant.  Tenant shall pay to Landlord on the
first day of each calendar month during such calendar year one-twelfth (1/12) of
the amount of such estimated increases in operating expenses and direct taxes
payable by Tenant hereunder; provided,  however,  that Tenant shall not be
responsible for any increases in operating expenses or direct taxes allocable to
the first twelve (12) months of the term of this Lease.  Statements of the
amount of actual operating expenses for the preceding calendar year and the Base
Year, 

                                       2

 
of direct taxes for the appropriateyear and the Base Year and of the
amount of such increases payable by Tenant shall be given to Tenant on such date
as Landlord shall from time to time determine during each calendar year
subsequent to the calendar year immediately next succeeding the Base Year.  All
amounts payable by Tenant as shown on said statement, less any amounts
theretofore paid by Tenant on account of Landlord' 5 estimate of increases in
operating expenses and direct taxes made pursuant to this paragraph 5.2, shall
be paid by Tenant upon delivery of said statement to Tenant. In the event that
the Tenant has paid in any given year estimated increases beyond those later
determined from actual reconciliation, then such overpayment shall be applied
toward the Rent for the following year or, if the Lease has terminated and not
been renewed as provided herein, such overpayment shall be promptly refunded to
Tenant.

         (b) The amount of any increase in operating expenses and direct taxes
payable by Tenant for the first calendar year of the term and the calendar year
in which this Lease terminates shall be prorated on the basis in which the
number of days from and including the commencement of said calendar year to and
including the date on which this Lease terminates bears to 365 and shall be due
and payable when rendered notwithstanding termination of this Lease.

         (c) The term "operating expenses" as used herein shall include all
direct costs of operation, maintenance and management of the Building, including
the Premises, as determined by generally accepted accounting practices, except
those costs which are the exclusive responsibility of the Tenant or any other
tenant of the Building under this lease or other applicable leases.  By way of
illustration, but not limitation, operating expenses shall include the cost or
charges for the following items: heat, light, water, sewer, power, steam, and
other utilities (including without limitation any temporary or permanent utility
surcharge or other exaction, whether now or hereafter imposed), waste disposal,
janitorial services, guard services, window cleaning, air conditioning,
materials and supplies, equipment and tools, service agreements on equipment,
insurance premiums,  licenses, permits and inspections,  wages and salaries,
employee benefits and payroll taxes, accounting and legal expenses, management
fees, and the reasonable cost of contesting the validity or applicability of any
governmental enactments which may affect operating expenses, not to exceed the
cost savings realized.

        Notwithstanding anything to the contrary in this Lease Tenant shall not
be obligated to perform or to pay or reimburse Landlord for any of the
following: (i) costs occasioned by fire, acts of God, or other casualties or by
the exercise of the power of eminent domain, (ii) costs which would properly be
capitalized under generally accepted accounting principles ("GAAP") except to
the extent that (a) the foregoing reduces the expenses otherwise payable by
Tenant under this Lease and (b) Tenant's share of such cost during any twelve-
month period of the Lease is amortized over the useful life of the capital item
in question determined in accordance with GAAP, (iii) costs for which Landlord
has a right of reimbursement from others, (iv) costs to comply with any Law
applicable to the Premises or the building on the Tenth Floor Commencement Date,
(v) costs arising from the disproportionate use of any utility or service
supplied by Landlord to any other occupant of the building, (vi) depreciation or
expense reserves, (vii) interest, charges and fees incurred on debt, payments on
mortgages and rent under ground leases, (viii) insurance premiums for coverage
not customarily paid by tenants of similar projects in the vicinity of the
Premises or that are not commercially reasonable, insurance deductibles, and co-
insurance payments, (ix) a management fee in excess of 5% of all actual
operating expenses, and (x) costs for maintenance, repair or replacement to or
of the structural elements of the building.

         The term "direct taxes" as used herein shall include all real property
taxes and assessments on the Building, the land on which the Building is
situated, and the various estates in the Building and the land.  Direct taxes
shall also include all personal property taxes levied on the property used in
the 
                                       3

 
operation of the Building; taxes of every kind and naturewhatsoever levied
and assessed in lieu of, in substitution for, or in addition to, existing or
additional real or personal property taxes on said Building, land or personal
property, whether or not now customary or within the contemplation of the
parties hereto, other than taxes covered by paragraph 22 to the extent that
Landlord is reimbursed therefor by Tenant or by any other tenant of the
Building; taxes upon the gross or net rental income of Landlord derived from the
Building and land (excluding, however, state and federal gift, inheritance,
personal or corporate income taxes measured by the income of Landlord from all
sources) and the reasonable cost of Landlord of contesting the amount or
validity or applicability of any of the aforementioned taxes not to exceed the
cost savings realized. Net recoveries through protest, appeals or other actions
taken by Landlord in its discretion, after deduction of all costs and expenses,
including counsel and other fees, shall be deducted from direct taxes for the
year of receipt.

        (d) The annual determination and statement of operating expenses and
direct taxes shall be made by an accounting or auditing officer designated by
Landlord.  A copy of said determination shall be made available to Tenant upon
demand. If the Tenant contests such statement in writing within thirty (30) days
after receipt thereof, the Tenant shall have the right to have the statement
audited, at Tenant's cost, in conformity with generally accepted accounting
procedures, by an accounting firm mutually acceptable to Landlord and Tenant.
The audit shall be binding on the parties; if the audit determines an
overpayment by the Tenant, the Landlord shall promptly refund the amount of such
overpayment to Tenant.

        (e) The Base Year referred to hereinabove is defined as the calendar
year 1996.

        The Base Tax Year referred hereinabove is defined as the fiscal year
ending 1996.

        Tenant's Share, as referred to hereinabove, is 27.45% which amount is
subject to adjustment pursuant to paragraph 1.  Tenant's Share is calculated by
dividing the number of rentable square feet in the Premises by the number of
rentable square feet in the building which has been determined to be 131,862.
When all three floors are entirely delivered, Tenant's Share shall be 27.45%.
Until that time, Tenant Share shall be the resulting quotient determined in
accordance with the formula set forth above.

        (f) The Minimum Rent and the Additional Rent are hereinafter sometimes
individually or collectively referred to as the Rent, as applicable.

        5.3  Prepaid Rent.   On execution of this Lease, Tenant shall pay
             ------------
$40,220 to Landlord, which shall be credited to Tenant's payment of the Minimum
Rent for the first two months of the initial term for which Tenant must pay the
Minimum Rent.  Landlord shall not be required to pay Tenant interest on the
prepaid rent.

        5.4  Security Deposit.  Prior to the expiration of the Letter of Credit
             ----------------
as described in paragraph   of Rider No. 1, Tenant shall deposit with Landlord
the greater of $60,330.00 or an amount equal to one month's base rent for the
Premises as a security deposit for the performance by Tenant of the provisions
of this Lease.  If Tenant is in default, Landlord can use the security deposit,
or any portion of it, to cure the default or to compensate Landlord for all
damage sustained by Landlord resulting from Tenant's default. Tenant shall
immediately on demand pay to Landlord a sum equal to the portion of the security
deposit expended or applied by Landlord as provided in this paragraph so as to
maintain the security deposit in the sum initially deposited with Landlord.  If
Tenant is not in default at the expiration or termination of this Lease,
Landlord shall return the security deposit to Tenant.  Landlord's obligations
with respect to the security deposit are those of a debtor and not a trustee.
Landlord can 

                                       4

 
maintain the security depositseparate and apart from Landlord's general funds or
can commingle the security deposit with Landlord's general and other funds. At
the termination of the Lease and provided the Tenant is not in default, the
portion of the security deposit to which the Tenant is entitled, shall be
returned to the Tenant together with interest computed at 3% per annum simple
interest.

        5.5  Payment of Rent.  The Tenant agrees to pay said Rent to the
             ---------------
Landlord, without deduction, demand or offset, in lawful money of the United
States of America, at the office of the Landlord at 2101 Market Street, San
Francisco, CA 94114, or to such other person or at such other place as the
Landlord may from time to time designate in writing.

        No security or guaranty, which may now or hereafter be furnished to the
Landlord for the payment of the Rent herein reserved or for performance by the
Tenant of the other covenants or conditions of this Lease, shall in any way be a
bar or defense to any action in unlawful detainer, or for the recovery of the
Premises, or to any action which the Landlord may at any time commence for a
breach of any of the covenants or conditions of this Lease.

          5.6  Option to Renew.
               ----------------

          (a) Provided that Tenant is not in material default hereunder and that
the Tenant named herein (and not a sublessee or assignee, except a Permitted
Transferee as defined herein) is then occupying at least one-third of the entire
Premises demised hereunder, Tenant shall have the option to renew this Lease for
one additional term of, at Tenant's option, six (6) months minimum to twenty
four (24) months maximum commencing upon expiration of the initial term of the
Lease.

          (b) If Tenant wishes to exercise said option, Tenant must do so by
written notice given to Landlord not less than six (6) months prior to
expiration of the initial term.

          (c) If the Tenant exercises said option, the renewal lease shall be on
all the same terms and conditions as set forth herein as applicable to the
initial term (as the initial term is defined in paragraph 3.1 hereof), excepting
as follows: (i) the option so exercised shall not itself be renewed; (ii) the
Landlord shall have no obligation to pay for any alterations or improvements to
the Premises (as the Premises may then be constituted); (iii) the Base Year
shall be the calendar year in which such renewal term commences; and (iv) the
Minimum Rent payable by Tenant for and during the applicable renewal period
shall be an amount which is equal to 100% of the prevailing fair market rent for
the Premises for the option period as of the date of commencement of the
applicable extended term, as shall be mutually agreed upon in writing by
Landlord and Tenant within thirty (30) days after exercise of option; the
prevailing fair market value shall be net of leasing commissions and Tenant
shall be solely responsible for leasing commissions should he retain the
services of an agent.  In no event shall the Minimum Rent for any extended term
be less than the Minimum Rent in effect during the last year of the preceding
term.  Landlord represents that Landlord is not obligated to pay to
Stubbs/Collenette any commissions on account of the option to renew.

          If the parties are unable to agree on the Minimum Rent for the
extended term within such thirty (30) day period, then within ten (10) days
after the expiration of such thirty (30) day period, each party, at its cost and
by giving notice to the other party, shall appoint a real estate appraiser with
at least five (5) years full time commercial appraisal experience in the area in
which the Premises are located to appraise and set the Minimum Rent.  If a party
does not appoint an appraiser, the single appraiser appointed shall be the sole
appraiser and shall set the Minimum Rent for the extended term.   If the two
appraisers are appointed by the parties as stated in this paragraph, they shall

                                       5

 
meet within thirty (30) days after the last appraiser isappointed and if, within
ten (10) business day. after such first meeting, the two appraisers are unable
to agree promptly upon the amount of the Minimum Rent for the extended term,
they, themselves, shall within ten (10) business days thereafter appoint a third
appraiser meeting the qualifications stated in this paragraph; in the event that
the two appraisers are unable to agree upon the appointment of a third appraiser
within such ten (10) business days, either of the parties to this Lease, by
given ten (10) days notice to the other party, can apply to the then president
of the county real estate board of the county in which the Premises are located,
or to the presiding judge of the Superior Court of that county, for the
selection of a third appraiser who meets the qualifications stated in this
paragraph.  Each of the parties shall bear one-half of the cost of appointing
the third appraiser and paying the third appraiser's fee.  The third appraiser,
however selected, shall be a person who has not previously acted in any capacity
for either party.  In the event of the failure, refusal or inability of any
appraiser to act, his successor shall be appointed by him within a period of ten
(10) days but, in the case of the third appraiser, his successor shall be
appointed as hereinabove provided.

          Within thirty (30) days after the selection of the third appraiser, a
majority of the appraisers shall set the Minimum Rent for the extended term. If
a majority. of the appraisers are unable to set the Minimum Rent within the
stipulated period of time, the three appraisals shall be added together and
their total divided by three; the resulting quotient shall be the Minimum Rent
for the Premises during the extended term.

          If, however, the low appraisal and/or the high appraisal are/is more
than 10% lower and/or higher than the middle appraisal, the low appraisal and/or
the high appraisal shall be disregarded.  If only one appraisal is disregarded,
the remaining two appraisals shall be added together and their total divided by
two; the resulting quotient shall be the Minimum Rent for the Premises during
the extended term.  If both the low appraisal and the high appraisal are
disregarded as stated in this paragraph, the middle appraisal shall be the
Minimum Rent for the Premises during the extended term.

        6.  Common Areas.  Tenant, its employees and invitees may, except as
            ------------
otherwise specifically provided in this Lease, use the common areas of the
Building as such common areas may be designated from time to time by Landlord
(the "Common Areas"), in common with other persons for ingress and egress and
open-space purposes and for other purposes specifically designated by Landlord
during the term of this Lease, which use shall be subject to the restrictions
set forth in this Lease (including, without limitation, the Rules and
Regulations) and any further reasonable restrictions promulgated by Landlord
from time to time. Landlord shall at all times have the right and privilege of
determining the nature and extent of the Common Areas and of making such changes
therein and thereto from time to time which, in its reasonable opinion, are
deemed to be desirable and for the best interests of all persons using the
Common Areas and of Landlord, including, without limitation, the withdrawal of
any portion thereof and the relocation of driveways, entrances, exits,
corridors, automobile parking spaces (if any), the direction and flow of
traffic, installation of prohibited areas, landscaped areas, and all other
facilities thereof.  Nothing contained herein shall be deemed to create any
liability upon Landlord for any injury to or death of persons or for damage to
or destruction of property, including, without limitation, for any damage to
motor vehicles of Tenant, its customers or employees, or for loss of property
from within such motor vehicles, unless caused by the negligence of Landlord,
its agents, contractors, servants or employees. Landlord shall at all times
during the term of this Lease have the sole and exclusive control of the Common
Areas and may at any time and from time to time during the term hereof exclude
and restrain any person from use or occupancy thereof excepting, however, bona
fide invitees of Tenant and other tenants of Landlord who make use of said
Common Areas in accordance with the Rules and Regulations pertaining thereto.
The rights of Tenant hereunder in and to the

                                       6

 
Common Areas shall at all times be subject to the rights of Landlord and other
tenants of Landlord who use the same in common with Tenant, and it shall be the
duty of Tenant to keep all the Common Areas free and clear of any obstructions
created or permitted by Tenant or resulting from Tenant's operation, and to
permit the use of any of the Common Areas only for ingress and egress by the
invitees of Tenant to and from the Building. If, in the opinion of Landlord,
unauthorized persons are using the Common Areas by reason of the presence of
Tenant in the Leased Premises, Tenant, upon demand of Landlord, shall correct
such situation by appropriate action or proceedings against all such
unauthorized persons. Nothing herein shall affect the right of Landlord at any
time to remove any such unauthorized persons from said areas or to prevent the
use of any of said areas by unauthorized persons.

        7.  Uses Prohibited.  The Tenant shall not do or permit anything to be
            ---------------
anything therein, which will in any way increase the rate of or affect any fire
or other insurance upon the Building or any of its contents, or cause a
cancellation of any insurance policy covering the Building or its contents.  The
Tenant shall, at its sole cost and expense, comply with any and all requirements
pertaining to the Premises of any insurance organization or company necessary
for the maintenance of the fire and public liability insurance covering the
Premises. The Tenant shall not do or permit anything to be done in or about the
Premises which will in any way obstruct or interfere with the rights of other
tenants or occupants of the Building or injure or annoy them, or use or allow
the Premises to be used for any immoral, unlawful, hazardous or objectionable
purposes, and the Tenant shall not cause, maintain or permit any nuisance in, on
or about the Premises.  The Tenant shall not change the use of the Premises in
any way that will result in a conflict with any other lease of premises in the
Building; provided, however, that Tenant shall always have the right to use the
Premises for offices and training. No loudspeakers or other similar device,
system or apparatus which can be heard or experienced outside the Premises
shall, without the prior written approval of the Landlord, be used in or at the
Premises.  The Tenant shall not commit or suffer to be committed any waste in or
upon the Premises.  The Tenant agrees immediately upon the discovery of any such
unlawful, illegal, disreputable or extra hazardous use, to take all necessary
steps, legal and equitable, to compel the discontinuance of such use and to oust
and remove any subtenants, occupants or other persons guilty of such unlawful,
illegal, disreputable or extra hazardous use.   The Tenant shall indemnify and
save harmless the Landlord against and from all costs, expenses, liabilities,
losses, damages, injunctions, suits, fines, penalties, claims and demands,
including reasonable counsel fees, arising out of, by reason of, or on account
of, any violation of or default in the covenants of this paragraph.  The
provisions of this paragraph are for the benefit of the Landlord only and are
not nor shall they be construed to be for the benefit of any tenant or occupant
of the Building.

        8.  Compliance with Law.  The Tenant shall not use or permit anything to
            -------------------
be done in or about the Premises which will in any way conflict with any law,
statute, ordinance or governmental rule, regulation or requirement now in force
or which may hereafter be enacted or promulgated.  The Tenant, at its sole cost
and expense, shall promptly comply with all laws, statutes, ordinances and
governmental rules, regulations or requirements now in force or which may
hereafter be in force (collectively, "Laws") and with the requirements of any
board of fire underwriters or other similar body now or hereafter constituted
regulating the Tenant's improvements, acts or omissions.  The judgment of any
court of competent jurisdiction or the admission of the Tenant in an action
against the Tenant (whether the Landlord be a party thereto or not) that the
Tenant has violated any law, statute, ordinance or governmental rule, regulation
or requirement shall be conclusive of that fact as between the Landlord and the
Tenant.


        9.  Certificates of Occupancy.  Tenant shall not at any time use or
            -------------------------
                                       7

 
occupy the Leased Premises in violation of the certificates of occupancy or of
any present or future governmental orders or directives issued for the Building.
In the event that any department of the City or County in which the Building is
located, or of the State of California, shall hereafter at any time contend or
declare that the Premises are used for a purpose which is in violation of such
certificate or certificates of occupancy, Tenant shall, upon five (5) days
notice from Landlord or any governmental agency, immediately discontinue such
use of the Premises.  Failure by Tenant to discontinue such use after such
notice shall be considered a default under this Lease and Landlord shall have
the right to terminate this Lease immediately, and in addition thereto shall
have the right to exercise any and all rights and privileges and remedies given
to Landlord by and pursuant to the provisions of paragraph 28 hereof.  The
statement in this Lease of the nature of the business to be conducted by Tenant
in the Premises shall not be deemed or construed to constitute a representation
or guaranty by Landlord that such business is lawful or permissible or will
continue to be lawful or permissible under any certificate of occupancy issued
for the Building, or otherwise permitted by law.


        10.  Improvements and Alterations.  Except to the extent provided to the
             ----------------------------
contrary herein,  the Tenant shall take the Premises in their "ASIS" condition.
The Tenant shall not make or suffer to be made any alterations, additions or
improvements to or of the Premises or any part thereof, except as expressly
provided in this paragraph 10.


        Tenant may cause such alterations, additions or improvements to be made
only upon the following conditions:

        (a) By a contractor reasonably approved in writing by the Landlord in
advance;

        (b) Tenant submits plans, specifications and cost estimates of such work
prepared by a competent architect in accordance with existing building
ordinances of federal, state or local laws or orders to the Landlord for the
Landlord's approval which Landlord shall not unreasonably withhold.  Default by
the Tenant in the payment of any sums agreed to be paid by the Tenant to
Landlord for or in connection with alterations, additions or improvements to the
Premises shall entitle the Landlord to all the same remedies as for nonpayment
of Rent hereunder.  Any alterations, additions or improvements to or of the
Premises shall at once become the property of the Landlord.  Movable furniture,
equipment and trade fixtures shall remain the property of the Tenant.  The
Landlord shall indicate to the Tenant when Landlord's approval of the above
plans  and specifications is sought which alterations, additions or improvements
made for or by the Tenant will be required to be removed from the Premises at
the termination of this Lease.  If the Landlord so elects, the Tenant shall
restore the Premises to the condition of same prior to the making of such
alterations, additions or improvements which are so required to be removed at
the termination of this lease; said work of removal and restoration shall be
performed, at the Landlord's sole election, either (i) by the Tenant, at the
Tenant's sole cost and expense, or (ii) by the Landlord at the expense of the
Tenant and, in the latter election, the Tenant shall pay to the Landlord,
promptly upon the Landlord's demand, the amount of the Landlord's reasonable
cost of such removal and restoration.  Prior to the commencement of Landlord' 5
removal and or restoration work, Landlord shall submit the cost estimate to
Tenant and Tenant shall have the right to reasonably approve such estimate and
any amendments thereto.  In the event that, as a result of any such alterations,
additions or improvements, it shall be necessary for the Landlord to make other
improvements (including, but not limited to, upgrading of installations of life
safety systems or compliance with standards for handicapped persons) in the
Building, whether within or without the Premises, then the Tenant agrees to pay
the cost of such other improvements if they are a condition of the building
permit; provided however, that Tenant shall not be responsible for any costs or
improvements (i) made necessary as a result of the failure of Landlord or any
occupant of the Building to obtain building permits, where required and/or 

                                       8

 
(ii) to comply with any Laws (a) applicable thePremises as of the date the
construction of Tenant's tenant improvements are completed by Landlord and/or
(b) applicable to the Building as of the Tenth floor Commencement Date. Landlord
shall be responsible for those costs and improvements that are not the
responsibility of Tenant.

        (c) Upon request, Tenant shall procure and deliver to Landlord evidence
of compliance with all applicable laws, ordinances, rules, regulations and
requirements for permits and approvals.  Sufficient evidence will be deemed to
be normal approvals, permits and certificates required or provided by entities
with jurisdiction over the performance of the construction at the Premises;

        (d) Tenant shall deliver to Landlord evidence that Tenant has procured
or caused procurement  of  (i)  "builder's  risk" insurance,  (ii)  workers'
compensation insurance covering all persons employed in connection with the work
for whom death or bodily injury claims could be asserted against Landlord or the
Premises, and (iii) the policies of insurance required to be obtained by Tenant
under paragraph 16 of this Lease.  Tenant or its contractor shall pay all
premiums required to maintain the insurance hereinabove described at all times
during the performance of the work and shall, immediately upon receipt, deliver
to Landlord copies of insurance certificates for the policies required.  Such
certificates shall include an additional named insured endorsement in favor of
Landlord and a provision that in the event of cancellation, nonrenewal or
change in coverage, the insurance carrier will send Landlord a notice thereof at
least thirty (30) days preceding the effective date of cancellation, nonrenewal
or change in coverage;

        (e) Tenant shall give Landlord ten (10) days advance written notice of
Tenant's intention to commence work or delivery of building materials.   The
notice shall specify the nature of the work.  Landlord shall have the right to
post and maintain on the Premises any notices of nonresponsibility provided for
under applicable law, and to enter the Premises upon twentyfour (24) hour
notice, except in the case of emergency, where no notice shall be required, and
inspect the construction at all reasonable times;

        (f) If Tenant installs any electrical equipment that overloads the lines
of the Premises or the Building, Landlord may require Tenant to make whatever
changes to the lines as may be necessary to render same in good order and
repair, and in compliance with all insurance requirements and applicable legal
requirements;

        (g) Tenant shall construct all work in a good and workmanlike manner, in
compliance with the plans and specifications approved by Landlord and with all
applicable laws, ordinances, rules, regulations and requirements for permits and
approvals;

        (h) Within 30 days after completion of the work, Tenant shall record a
notice of completion; and

        (i) On completion of any work, Tenant shall supply Landlord with the
final plans obtained by Tenant, including "asbuilt" drawings, if obtained,
which shall accurately reflect all such work as completed.

        11.  Repair.   Except as otherwise provided herein, by entry upon
             ------
commencement of the term hereof, the Tenant acknowledges and accepts the
Premises as being in good, sanitary order, condition and repair.  Except to the
extent provided to the contrary in paragraph 17, the Tenant, at the Tenant's
sole cost and expense, agrees to keep the Premises and every part thereof
(including its own trade fixtures and personal property) in good condition and
repair.  Tenant hereby waives all rights to make repairs at the expense of the
Landlord as provided by law, statute or ordinance now or hereafter in effect, or
to offset the cost thereof against Rent.  Except as otherwise provided in this
Lease, it is 

                                       9

 
specifically understood and agreed that the Landlord has no obligation and has
made no promises to alter, remodel, improve, repair, decorate or paint the
Premises or any part thereof and, except as expressly set forth in this Lease,
no representations respecting the condition of the Premises or the Building have
been made by the Landlord to the Tenant. If, in an emergency, it shall become
necessary to make promptly any repairs or replacements required to be made by
Tenant, Landlord may reenter the Premises and proceed forthwith to have the
repairs or replacements made and pay the cost thereof. Within thirty (30) days
after Landlord renders a bill therefor, Tenant shall reimburse Landlord for the
cost of making the repairs. Notwithstanding anything to the contrary in this
Lease, Landlord, and not Tenant, shall perform and construct, any repair,
maintenance or improvement (i) required as a consequence of any violation of Law
or construction defect in the Premises as of the applicable Commencement Date,
(ii) for which Landlord has a right of reimbursement from others, (iii) which
would be treated as a "capital expenditure" under generally accepted accounting
principles, and (iv) to the heating, ventilating, air conditioning, electrical,
water, sewer, and plumbing systems serving the Premises. Tenant' s obligation,
if any, to reimburse Landlord for the costs of such repairs, maintenance and
improvements shall be governed by the other provisions of this Lease.


        12.  Abandonment.  The Tenant shall not abandon the Premises at any time
             -----------
during the term hereof and, if the Tenant shall abandon or surrender the
Premises, or be dispossessed by process of law, or otherwise, any personal
property belonging to the Tenant and left on the Premises shall be deemed to be
abandoned at the option of the Landlord, except such property as may be security
for a debt to the Landlord.


         13.  Liens.  Tenant agrees to keep the Premises, and every part
              -----
thereof, at all times during the term of this Lease, free and clear of
mechanics' liens and other liens for labor, services, supplies, equipment or
material, furnished to the Premises on account of work performed by Tenant or
anyone claiming on behalf of Tenant or through Tenant and that it will at all
times fully and promptly pay and discharge and wholly protect and save harmless,
by bond or otherwise, the Landlord, and all and every part of the estate, right,
title and interest of the Landlord in and to all and every part of the Premises,
against any and all such demands or claims which may or could ripen into such
liens or claims therefore; the Tenant agrees to give the Landlord not less than
ten (10) days notice in writing in advance of the commencement of any
construction, alteration, addition or repair of the Premises in order that the
Landlord may post an appropriate notice of Landlord's nonresponsibility
therefor.


         14.  Assignment and Subletting.
              -------------------------

         (a) In entering this Lease for the term and of the provisions of this
Lease, Landlord has relied upon Tenant's business reputation and experience.
Accordingly, Tenant agrees that it will not mortgage or hypothecate this Lease
or any interest therein.  Tenant may not assign this Lease or sublet the
Premises without first having obtained the written consent of the Landlord.
Such consent by Landlord shall not be unreasonably withheld. Tenant agrees that
should Tenant assign this Lease or sublet all or a portion of the Premises,
Tenant will remain fully liable on and responsible for payment of the Rent and
the other terms, conditions, covenants and duties of this Lease.  Tenant shall
not sublet all or portion of the Premises for any period of time extending
beyond the period of this Lease or any renewal thereof. The Tenant agrees that
reasonable grounds for the Landlord's refusal to consent shall include, but not
be limited to:   (1) financial instability of the proposed subtenant, and (2)
credit rating of the subtenant, if any.

        No permitted subtenant shall assign, mortgage,  pledge,  encumber,
transfer, modify, extend or renew its sublease or further sublet all or any
portion of its sublet space, or otherwise permit any portion of the sublet space
to be used or occupied by others, without the prior written consent of Landlord

                                      10

 
first had and obtained in each instance, which consent may be withheld in
Landlord's sole and absolute discretion, except that the Landlord may flat
unreasonably withhold its consent in the case of an assignee or sublessee of
this entire Lease, and each proposed sublease shall contain appropriate
restrictions in furtherance of  the  foregoing.   Any mortgage,  pledge,
hypothecation, encumbrance or transfer or any such assignment, subletting,
occupation or use without the consent of Landlord as aforesaid shall be void
and, at the option of Landlord, constitute a default entitling Landlord to
terminate this Lease and give rise to all other remedies available to Landlord
for breach of this Lease. For purposes of this paragraph 14, the following
events shall be deemed an assignment of this Lease or a sublease, as
appropriate:  (i) the issuance of equity interests in Tenant or any subtenant
(whether stock or partnership interests or otherwise) to any person or group of
related persons, in a single transaction or a series of related or unrelated
transactions,  such that, following such issuance, such person or group shall
have control of Tenant or such subtenant; or (ii) a transfer of control of
Tenant or of any subtenant in a single transaction or a series of related or
unrelated transactions (including, without limitation, by consolidation, merger
or reorganization), except that the transfer of the outstanding capital stock of
any corporate Tenant or subtenant (by persons or parties other than "insiders"
within the meaning of the Securities Exchange Act of 1934, as amended) through
the "overthe counter" market or any recognized national or international
securities exchange shall not be included in the determination of whether
control has been transferred.  "Control" shall mean ownership of not less than
51% of all of the voting stock of such corporation or not less than 51% of all
of the legal and equitable interest in any other business entity.  If this Lease
is assigned, whether or not in violation of the terms of this Lease, Landlord
may collect rent from the assignee.   If the Premises or any part thereof is
sublet or is used or occupied by anybody other than Tenant, Landlord may, after
default by Tenant, collect rent from such subtenant or occupant.  In either
event, Landlord may apply the next amount collected to the rents herein
reserved.   The consent by Landlord to an assignment, transfer, encumbering or
subletting pursuant to any provision of this Lease shall not relieve Tenant or
any assignee or subtenant from obtaining the express prior written consent of
Landlord to any other or further assignment, transfer, encumbering or
subletting.  Neither any assignment of this Lease or any interest created hereby
or any interest of Tenant in any sublease, nor any subletting, occupancy or use
of the Premises or any part thereof by any person other than Tenant, nor any
collection of rent by Landlord from any person other than Tenant,  nor any
application of any such rent as provided in this subparagraph (a) shall be
deemed a waiver of any of the provisions of this subparagraph,  or  (b)
relieve,  impair,  release or discharge Tenant of its obligation fully to
perform the terms of this Lease on Tenant ' s part to be performed, and Tenant
shall remain fully and primarily liable hereunder.

         (b) The Tenant agrees to pay to the Landlord the amount of the
Landlord's reasonable cost of processing every proposed subletting, (including,
without limitation, the costs of attorneys' and other professional fees and
administrative, accounting and clerical time of the Landlord), and the
reasonable amount of all direct and indirect expenses incurred by the Landlord
arising from any sublessee taking occupancy (including, without limitation,
freight elevator operation for moving of furnishings and trade fixtures,
security service, janitorial and cleaning service and rubbish removal service).
Notwithstanding anything herein to the contrary, the Landlord shall have no
obligation to process any request for such consent prior to the Landlord's
receipt of payment by the Tenant of the amount of the Landlord's estimate of the
processing costs and expenses and all other direct and indirect costs and
expenses of the Landlord and its agents arising from such proposed subletting.

         (c) In no event shall the Tenant assign this Lease or sublet the
Premises or any portion thereof to any then existing or prospective tenant of
the Building. However, Tenant shall have the right to assign this Lease orsublet
the Premises or any portion thereof to an existing tenant of the Building if (i)
the 

                                      12

 
sublease or the assignment is for less than the entire balance of the term
or extended term of the Lease and the Tenant will reoccupy the subleased or
assigned space once the sublease or the assignment is over, or (ii) only part of
the Premises is to be sublet or assigned and no dividing walls are to be built
between the space retained by Tenant and the sublet or assigned space.

         (d) In the event of (i) any permitted subletting at a greater rental
rate than the Rent payable by the Tenant hereunder or (ii) any permitted
subletting providing for payment of any consideration  (including,  without
limitation, payment for leasehold improvements) by the sublessee to the Tenant,
the amount of all such sublease rental and/or consideration which is in excess
of the Rent payable by the Tenant hereunder shall be paid to Landlord to the
extent consistent with paragraph 5 of Rider 1.

         (e) Notwithstanding anything to the contrary in this paragraph 14, and
provided Tenant remains liable under this Lease and is not released thereby,
Tenant may, without Landlord' 5 prior written consent and without being subject
to any of the provisions of this paragraph 14 including without limitation,
Landlord's right to participate in assignment and subletting proceeds, sublet
the Premises or assign the Lease to (collectively hereafter referred to as the
"permitted transferees"): (i) a subsidiary, affiliate, division or corporation
controlling, controlled by or under common control with Tenant; (ii) a successor
corporation related to  Tenant by merger,  consolidation  or  nonbankruptcy
reorganization; or (iii) a purchaser of substantially all of Tenant's assets.
Notwithstanding anything to the contrary in this paragraph 14, the sale or
transfer of Tenant's capital stock in connection with the merger, consolidation
or nonbankruptcy reorganization of Tenant shall not be deemed an assignment,
subletting, or any other transfer of the Lease or the Premises.

         15.  Indemnification.
              ---------------

         (a) Except for claims  resulting from the negligence or willful
misconduct of the Landlord or the holders of any Superior Interests, Landlord
and the holders of any Superior Interests (as defined in paragraph 25 hereof)
shall not be liable to Tenant and Tenant hereby waives all claims against such
parties for any loss, cost, damage, injury, illness or death suffered by any
person or damage to any property in or about the Premises or the real property
of which the Premises are a part by or from any cause whatsoever and, without
limiting the generality of the foregoing, whether caused by water leakage of any
character from the roof, walls, basement or other portion of the Premises or
said real property or caused by gas, fire, electricity or any cause whatsoever,
in, on or about the Premises or said real property or any part thereof.

         (b) Tenant shall hold Landlord and the holders of any Superior
Interests,  the respective individual partners therein and the  respective
shareholders thereof (as applicable), and all of their agents, contractors,
servants, officers, directors, employees and licensees (hereinafter collectively
called the "Indemnitees") harmless from and against any and all loss, cost,
liability, claim, damage and expense including, without limitation, penalties,
fines and reasonable attorneys' fees and expenses, incurred in connection with
or arising from any default by Tenant hereunder or from any loss, cost, damage,
injury, illness or death suffered by any person or damage to any property or
from any other cause whatsoever: (i) occurring in or on the Premises or any part
thereof arising at any time during the term of this Lease and from any cause
whatsoever other than by reason of the negligence or willful misconduct of any
of the Indemnitees or (ii) arising at any time and occurring in, on or about any
part of said real property other than the Premises  (including,  without
limitation, any facilities of said real property, such as elevators, stairways,
passageways, hallways, plaza areas or adjacent sidewalks the use of which Tenant
may have in common with other tenants of the building), to the extent such
injury, illness, death or damage shall be caused by any act, neglect or default
or omission of any duty with respect to the same by Tenant,  its agents,

                                      12

 
employees, invitees or licensees except to the extent caused by the negligence
or willful misconduct of any of the Indemnities.  The provisions of this
paragraph 15(b) shall survive the termination of this Lease with respect to any
injury, illness, death or damage occurring prior to such termination.  In case
any action or proceeding be brought against any of the Indemnitees by reason of
any such claim or liability, Tenant upon notice from Landlord covenants to
resist and defend such action or proceeding by counsel reasonably satisfactory
to Landlord, with the cost to be shared between Tenant and Landlord in
accordance with their respective responsibility.   Except for damages caused by
the negligence or willful misconduct of the Indemnitees, Tenant, as a material
part of the consideration to Landlord for this Lease, hereby assumes all risks
of damage to property (to whomever belonging) in, upon or about the Premises
from any source, and Tenant hereby waives all claims in respect thereof against
the Indemnitees. In the event of any inconsistency between the terms of this
Paragraph 15 and the terms of paragraph 17, the terms of paragraph 17 shall
prevail.

         16.  Insurance.
              ---------

         (a) The Tenant agrees to keep in force during the term hereof, at the
Tenant's  expense,  comprehensive general liability insurance,  including
contractual liability insurance,  with a minimum combined single limit of
liability of One Million dollars and no/100 ($1,000,000.00) per occurrence for
injuries to or death of persons and damage to property occurring in or about the
Premises and its appurtenances.  Said policy shall name the Landlord and any
other parties designated by the Landlord as additional insureds and the policy
shall contain cross liability endorsements; shall insure the Landlord's and such
other parties' contingent liability as respects acts or omissions of the Tenant;
shall be issued by an insurance company licensed to do business in the State of
California and approved by the Landlord, which approval Landlord shall not
unreasonably withhold; shall specifically include the liability assumed by the
Tenant under this Lease (provided, however, that such contractual liability
coverage shall not satisfy the Tenant's indemnity obligations under this Lease);
shall provide that said insurance shall not be canceled or coverage thereof
changed unless thirty (30) days prior written notice from the insurer to the
Landlord is given first. The Landlord reserves the right to increase the
foregoing amount of insurance from time to time as the Landlord's insurance
broker reasonably determines is required to adequately protect the Landlord and
the other parties designated by the Landlord from the matters insured against,
provided that such amounts are customary in the vicinity of the Premises.

         (b) Said policy or a certificate thereof shall be delivered to the
Landlord by the Tenant upon commencement of the term, and thereafter there shall
be delivered to the Landlord by the Tenant renewal policies or certificates at
least thirty (30) days in advance of the expiration dates of expiring policies.
In the event the Tenant shall fail to procure such insurance, or to deliver such
policies or certificates, the Landlord may, at its option, and without
obligation to do so, procure the same for the account of the Tenant, and the
cost thereof shall be paid to the Landlord by the Tenant upon demand.

         (c) The Tenant agrees additionally to keep in force during the entire
term hereof, at the Tenant' 5 expense, Property Insurance, including Special
Form coverage on any and all improvements and alterations installed in the
Premises by or for the Tenant and all the Tenant's furnishings and equipment,
and personal property in the Premises, which insurance shall be in an amount of
not less than their full replacement value naming the Landlord as additional
insured. The Landlord agrees to use the proceeds from any such policy to replace
personal property and restore improvements or alterations.

         (d) The Tenant shall, throughout the term of this Lease, procure and
effect Workers' Compensation insurance as required by law.

         (e) Lessor shall obtain and keep in force during the term of this 

                                      13

 
Lease a policy or policies of insurance covering loss or damage to theBuilding,
but not Lessee's personal property, fixtures, equipment, or tenant improvements,
in the amount of full replacement cost thereof, providing protection against all
perils included within the classification of fire, extended coverage, vandalism,
malicious mischief, and such other perils as Lessor deems advisable or may be
required by any lender having a lien on the Building; Lessor shall not be
required to carry earthquake insurance.

        17.  Mutual Waiver of Subrogation.  Landlord waives any and all rights
             ----------------------------
of recovery against Tenant for or arising out of damage to or destruction of the
Building, or Leased Premises, or any other property of Landlord from causes then
included under standard fire and extended coverage insurance policies or
endorsements, whether or not such damage or destruction shall have been caused
by the negligence of Tenant, its agents, servants, employees, contractors,
visitors or licensees, but only to the extent that Landlord's insurance policies
then in force permit such waiver and only to the extent of actual recovery from
the insurance company.  Tenant also waives any and all rights of recovery
against Landlord for or arising out of damage to or destruction of any property
of Tenant, from causes then included under standard fire and extended coverage
insurance policies or endorsements, whether or not caused by the negligence of
Landlord, its agents, servants, employees, contractors, visitors or licensees,
but only to the extent that Tenant's insurance policies then in force permit
such waiver and only to the extent of actual recovery from the insurance
company. Landlord and Tenant represent that their present insurance policies now
in force permit such waiver.

        If, at any time during the term of this Lease, either party shall give
no less than fifteen (15) days prior notice to the other certifying that any
insurance carrier which shall have issued any such policy covering any of the
property above mentioned shall refuse to consent to the aforesaid waiver of
subrogation, or such carrier shall revoke a consent previously given or shall
cancel or threaten to cancel any policy previously issued and then in force and
effect, because of such waiver of subrogation, then, in any of such events, the
waiver in this paragraph shall thereupon be of no further force or effect as to
the loss, damage or destruction covered by such policy; provided however, that
if at any time thereafter such consent shall be obtained therefor, the waiver
hereinabove provided for shall again become effective.

        18.  Services and Utilities.
             ----------------------

        (a) The Landlord shall furnish to the Premises, during the period from
6:00 A.M. to 6:00 P.M. on business days Monday through Friday, excepting federal
and state holidays, and subject to the Rules and Regulations of the Building and
to federal, state and local codes and directives of governmental agencies or the
public utility company furnishing the service, or as otherwise determined by the
Landlord, the following:  (i) electricity for lighting and power suitable for
the use of the Premises for general office purposes, which shall be available at
all times; provided, however, that Tenant shall not at any time have a connected
electrical load for lighting purposes in excess of one (1) watt per square foot
of net rentable area of the Premises as determined by Landlord or a connected
load for all other power requirements in excess of two (2) watts per square foot
of net rentable area of the Premises as determined by Landlord, and the
electricity so provided for lighting and power shall not exceed such limits;
(ii) heat and air conditioning required in the Landlord's judgment for the
comfortable use and occupancy of the Premises for such purposes; (iii) water for
restroom and drinking purposes; (iv) elevator service by nonattended automatic
elevators for general office pedestrian usage, which shall be available at all
times; and (v) janitorial services limited to emptying and removal of general
office refuse, light vacuuming of floors as needed and window washing as
determined by the Landlord.

        (b) The Landlord shall not be liable for any loss or damage suffered

                                      14

 
by the Tenant or others by reason of the Landlord's failure to furnish any of
the services or utilities referred to in paragraph 18 (a) when such failure is
caused by acts of God, accidents, breakage, repairs, strikes, lockouts or other
labor disputes, the making of repairs, alterations or improvements to the
Premises or the Building, the inability to obtain an adequate supply of fuel,
water, electricity, labor or other supplies for any other condition beyond the
Landlord's reasonable control including, without limitation, any governmental
energy conservation program, and any such failure shall not constitute or be
construed as a constructive or other eviction of the Tenant. If Tenant's access
to the Premises or use thereof is prevented for more than five (5) working days
as a result of any of the above occurrences, then the Rent shall abate beginning
upon the 6th working day until Tenant's access to the Premises is restored. The
Landlord shall not be liable under any circumstances for loss of business or
injury to property however occurring, through or in connection with or
incidental to failure to furnish any of the services or utilities referred to in
paragraph 18(a). In the event any governmental entity promulgates or revises any
statute, ordinance or building, fire or other code, or establishes mandatory or
voluntary controls or guidelines applicable to the Property or the Premises or
any part thereof or appurtenances thereto, relating to the use or conservation
of energy, water, gas, light or electricity, or the reduction of automobile or
other emissions, or the provision of any other utility or service provided with
respect to this Lease, or in the event the Landlord is required or elects to
make alterations to the Building or any other part of the Property in order to
comply with such mandatory or voluntary controls or guidelines, or make such
alterations to the Building or any other part or said property related thereto,
such compliance and the making of such alterations shall in no event entitle the
Tenant to any damages, relieve the Tenant of the obligation to pay the full
monthly Rent reserved hereunder, or constitute or be construed as a constructive
or other eviction of the Tenant. Landlord shall not be obligated to provide or
maintain any security patrol or security system. Should Landlord elect to
provide such patrol or system, Landlord shall not be responsible for the quality
of any such patrol or system which may be provided hereunder, or for damage or
injury to Tenant, its employees, invitees or others due to failure, action or
inaction of such patrol or system.

        (c) Without the prior written consent of the Landlord, which consent may
not be unreasonably withheld, the Tenant will not use any apparatus or device in
the Premises  (including, without limitation, air conditioning equipment,
condenser pumps and condenser water, electronic data processing machines, punch
card machines, CRT (cathode ray tubes) and related equipment, supplementary
heating equipment, coffee makers, microwave ovens, fans or copy machines) which
will in any way cause the amount of electricity, water, heating, air
conditioning or ventilation furnished to the Premises to exceed the amount
thereof required for use of the Premises for general office purposes or to
exceed any limits established in paragraph 18(a), or connect with electric
current (except through existing outlets in the Premises) or water pipes any
apparatus or device for the purpose of using electric current or water.
Landlord acknowledges that Tenant's electrical requirement for the Premises will
exceed the amounts set forth in paragraph 18(a). Tenant agrees to either (a)
meter and bill Landlord for up to 3 watts per square foot, or (b) pay to
Landlord any electrical cost above 3 watts per square foot to be calculated
based on Tenant's current average consumption and use basis. Landlord and Tenant
agree to visit each other after three (3) months to discuss Tenant's electrical
usage if any major change in electrical usage occurs.

        (d) The Tenant shall pay for all services and utilities not required to
be furnished by the Landlord pursuant to paragraph 18 (a).  If the Tenant shall
require water, heat, air conditioning, electric current, elevator or janitorial
service in excess of that required to be furnished by the Landlord as specified
in paragraph 18(a), the Tenant must first obtain the written consent of the
Landlord to the use thereof, which the Landlord cannot unreasonably withhold. If

                                      15

 
the Landlord consents to an excess use of electriccurrent or water, the
Landlord, at its election, may cause an electric current or water meter
(including, without limitation, any additional wiring, conduit or panel required
therefor) to be installed in the Premises in order to measure the amount of
excess electric current or water consumed by the Tenant.  The Tenant agrees to
pay to the Landlord upon demand, in addition to the amounts set forth in
paragraphs 5.1 through 5.4 of this Lease, the following: the cost of any and all
water, heat, air conditioning, electric current, janitorial, elevator or other
services or utilities required by and furnished to the Tenant in excess of the
services and utilities required to be furnished by the Landlord as provided in
paragraph 18(a); the cost of any meter installed in the Premises and the cost of
the installation, maintenance and repair thereof; and any cost incurred by the
Landlord in keeping account of or determining such excess utilities or services
furnished to the Tenant.  The cost of the foregoing shall be determined by
methods (which may or may not include installation of separate meters as allowed
above) and in accordance with rates not in excess of that charged by the
applicable utility company.

        (e) The Landlord makes no representation with respect to the adequacy or
fitness of the heating, air conditioning or ventilation equipment in the
Building to maintain temperatures which may be required for, or because of, any
equipment of the Tenant other than normal fractional horsepower office
equipment, and the Landlord shall have no liability for loss or damage suffered
by the Tenant or others  in connection therewith.   If the temperature otherwise
maintained in any portion of the Premises by the heating, air conditioning or
ventilation systems is affected as a result of (i) any lights, machines or
equipment (including, without limitation, electronic data processing machines)
used by the Tenant in the Premises, (ii) the occupancy of the Premises by more
than one person per one hundred (100) square feet of net rentable area therein
or (iii) an electrical load for lighting and power in excess of that required
for general office purposes, the Landlord shall have the right to install any
machinery and equipment which the Landlord deems reasonably necessary to restore
temperature balance, including, without limitation, modification to the standard
air conditioning equipment, and the cost thereof including, without limitation,
the cost of installation and any additional cost of operation, maintenance or
repair incurred thereby, shall be paid by the Tenant to the Landlord upon
demand. Prior to the commencement of such work, Landlord shall submit the cost
estimate to Tenant and Tenant shall have the right to approve such estimate and
any amendments thereto. Tenant's approval shall not be unreasonably withheld.

        19.  Inability to Perform.  This Lease and the obligation of Tenant to
             --------------------
pay Rent hereunder and to keep, observe and perform all of the other terms,
covenants, conditions, provisions and agreements of this Lease on the part of
Tenant to be kept, observed or performed shall in no way be affected, impaired
or excused because Landlord is unable to fulfill any of its obligations under
this Lease or to supply, or is delayed or curtailed in supplying,  any service
expressly or impliedly to be supplied, or is unable to make or is delayed or
curtailed in making repairs, alterations, decorations, additions or
improvements, or is unable to supply, or is delayed or curtailed in supplying,
any equipment or fixtures, if Landlord is prevented, delayed or curtailed from
so doing by reason of any cause beyond Landlord's reasonable control, including,
but not limited to, acts of God, strike or labor troubles, fuel or energy
shortages, governmental preemption or curtailment in connection with a national
emergency or in connection with any rule, order, guideline or regulation of any
department or governmental agency, or by reason of the conditions of supply and
demand which have been or are affected by a war or other emergency.  Any such
prevention, delay or curtailment shall be deemed excused and Landlord shall not
be subject to any liability resulting therefrom.   However, if the Tenant's
access to the Premises or use thereof is prevented for more than five (5)
working days as a result of any of the above occurrences, then the Rent shall
abate beginning upon the 6th working day until Tenant's access to the Premises
is restored.

                                      16

 
        20.  Disruption of Services for Repair or Maintenance.  Landlord shall
             ------------------------------------------------
repair and maintain or cause to be repaired and maintained those portions of the
Building outside of the Premises and the structural portions of the Building,
but only those portions of the Building which are not required to be maintained
by Tenant hereunder. Landlord reserves the right to stop service of the
elevator, plumbing, heating, ventilating, air conditioning and electric or other
mechanical systems, or cleaning services, when necessary, by reason of accident
or emergency or for inspection, repairs, alterations, decorations, additions or
improvements which, in the reasonable judgment of Landlord, are desirable or
necessary to be made, until same shall have been completed, and shall further
have no responsibility or liability for failure to supply any of such services
in such instance. Landlord shall use all reasonable efforts to minimize the
inconvenience to Tenant from such disruptions or interruptions of services.

        21.  Life Safety System.  If there now is or shall be installed in the
             ------------------
Building a sprinkler system, heat or smoke detection system, or any other so
called life safety system, and any such system or any of its appliances shall be
damaged or injured or not in proper working order by reason of any act or
omission of Tenant, Tenant's agents, servants, employees, contractors, visitors
or licensees, Tenant shall forthwith restore the same to good working condition.
If the Insurance Services Offices or any other similar body or any bureau,
department or official of the state, county or city government, or any
governmental authority having jurisdiction, require that any changes,
modifications, alterations or additional equipment be made or supplied in or to
any such system by reason of Tenant's particular business, or the location of
partitions, trade fixtures, or other contents of the Premises, or if any such
changes, modifications, alterations or additional equipment required by reason
of Tenant's particular business or the location of partitions, trade fixtures,
or other contents of the Premises, become necessary to prevent the imposition of
a penalty or charge against the full allowance for any such system in the
insurance rate as fixed by said Office, or by any insurance company, Tenant
shall, at Tenant's expense, promptly make and supply such changes,
modifications, alterations or additional equipment, provided that Tenant's
obligations shall be limited to expenses for such damages, modifications,
alterations or additional equipment made or located within the Premises.

        22.  Personal Property and Other Taxes and Assessments.  The Tenant
             -------------------------------------------------
shall pay, before delinquency, any and all taxes levied or assessed and which
become payable during the term hereof upon the Tenant's equipment, furniture,
fixtures and other personal property located in the Premises, including any
carpeting installed by the Tenant, even though said carpeting has become a part
of the Premises. In the event said taxes are charged to or paid or payable by
the Landlord, the Tenant, forthwith upon demand therefor, shall reimburse the
Landlord for all of such taxes paid by the Landlord.


          23.  Rules and Regulations.  The Tenant agrees faithfully to observe
               ---------------------
and comply with the Rules and Regulations printed on or annexed to this Lease
and all modifications of and additions thereto which the Landlord imposes and
communicates to all tenants of the Building from time to time. The Landlord
shall not be responsible to the Tenant for the nonperformance by any other
tenant or occupant of the Building of any of said Rules and Regulations.


          Landlord may waive any one or more of these Rules and Regulations for
the benefit of any particular tenant, but no such waiver by Landlord shall be
construed as a waiver of such Rules and Regulations in favor of any other tenant
or tenants, or prevent Landlord from thereafter enforcing any such Rules and
Regulations against any or all tenants of the Building.  Landlord reserves the
right to adopt other reasonable rules and regulations as may in its judgment be
needed from time to time for safety and security, for care and cleanliness of
the Building and for the preservation of good order therein.  Tenant agrees to
abide by such Rules and Regulations and any additional rules and regulations
which are 

                                      17

 
adopted.

        24.  Holding Over.  If the Tenant shall retain possession of the
             ------------
Premises or part thereof after expiration of the term hereof, by lapse of time
or otherwise, then the Tenant agrees to pay the Landlord for each month of such
retention a Minimum Rent equal to one and onehalf (11/2) times the Minimum
Rent payable under this Lease for the last full month period prior to the date
of such expiration, and agrees to indemnify the Landlord against all losses,
costs, claims, liabilities and expenses  (including, without limitation,
reasonable attorneys' fees and expenses) sustained by the Landlord by reason of
such retention (including, without limitation, claims for damages by any other
person to wham the Landlord may have leased all or any part of the Premises
effective upon the expiration of the term of this Lease). This provision is in
addition to, and does not affect or waive the Landlord's right of reentry or
any other right or remedy available to the Landlord on account of such holding
over.

        25.  Subordination of Lease. This Lease shall be subject and subordinate
             ----------------------
at all times to all ground or underlying leases which may now exist or hereafter
be executed affecting the Property, or any part thereof, and to the lien of any
mortgages or deeds of trust in any amount or amounts whatsoever now or hereafter
placed on or against the Property, or any part thereof, or on or against the
Landlord's interest or estate therein, or on or against any ground or underlying
lease (any of the foregoing being a "Superior Interest"), without the necessity
of having further instruments on the part of the Tenant to effectuate such
subordination. Notwithstanding the foregoing, the Tenant covenants and agrees to
execute and deliver, upon demand, without charge, such further instruments in
form reasonably acceptable to Tenant evidencing such subordination of this Lease
to such ground or underlying leases and to the lien of any such mortgages or
deeds of trust as may be requested by the Landlord. In the event of foreclosure
or exercise of any power of sale under any mortgage or deed of trust superior to
this Lease or to which this Lease is subject or subordinate, the Tenant shall
upon demand attorn to the lessor under said ground or underlying lease, or to
the purchaser at any foreclosure sale or sale pursuant to the exercise of any
power of sale under any mortgage or deed of trust, in which event this Lease
shall not terminate and the Tenant shall automatically be and become the tenant
of said lessor under said ground or underlying lease or of said purchaser,
whichever shall make demand therefor. This Lease shall not be subject or
subordinate to any ground or underlying lease or to any lien, mortgage, deed of
trust, or security interest hereafter affecting the Premises, nor shall Tenant
be required to execute any documents subordinating this Lease, unless the ground
lessor, lender, or other holder of the interest to which this Lease would be
subordinated executes a recognition and nondisturbance agreement which (i)
provides that this Lease shall not be terminated so long as Tenant is not in
material default under this Lease and (ii) recognizes all of Tenant's rights
hereunder.

        26.  Entry by the Landlord.  Upon 24 hour notice to Tenant (except in
             ---------------------
the case of an emergency where no notice shall be required), the Landlord
reserves and shall at any and all reasonable times have the right to enter the
Premises to inspect the same, to show the Premises to prospective brokers,
agents, purchasers or, during the last six (6) months of the term, tenants, to
post notices of nonresponsibility, sale or other notices, and to alter, improve
or repair the Premises and any portion of the Building without abatement of
rent, and may for those purposes erect scaffolding and other necessary
structures where reasonably required by the character of the work to be
performed, always providing the entrance to the Premises shall not be blocked
thereby and further providing that the business of the Tenant shall not be
interfered with unreasonably. Landlord's entry shall be subject to Tenant's
reasonable security precautions and Tenant's right to accompany Landlord at all
times. The Tenant hereby waives any claim for damages for any injury, nuisance
or other inconvenience to or interference with the Tenant's business, any loss
of occupancy, business or quiet enjoyment of the Premises, and other loss
occasioned by such entry. For each of the aforesaid purposes, the Tenant agrees
that the 

                                      18

 
Landlord shall at all times have and retain a keywith which to unlock all of the
doors in, upon and about the Premises, excluding the Tenant's vaults and safes,
and the Landlord shall have the right to use any and all means which the
Landlord may deem proper to open said doors in an emergency in order to obtain
entry to the Premises, and any entry to the Premises obtained by the Landlord by
any of said means, or otherwise, shall not under any circumstances be construed
or deemed to be a forcible or unlawful entry into or a detainer of the Premises,
or an eviction of the Tenant from the Premises or any portion thereof.

          27.  Insolvency or Bankruptcy.  The Tenant hereby agrees that neither
               ------------------------
this Lease or any interest herein shall be assignable or transferable by
operation of law, pursuant to any proceedings under the Bankruptcy Code. It is
hereby mutually agreed, covenanted and understood by and between the parties
hereto that in the event any proceedings under the Bankruptcy Code or any
amendment thereto, whether commenced by or against the Tenant (provided that if
such proceeding be involuntary, the Tenant shall have thirty (30) days to
dismiss the same), or in the event the Tenant be adjudged insolvent, or if the
Tenant makes an assignment for the benefit of its creditors, or if a writ of
attachment or execution be levied on the leasehold estate created hereby or the
business of the Tenant operated upon the Premises or the assets of the Tenant
situate thereon and be not released or satisfied within ten (10) days
thereafter, or if any receiver be appointed in any proceeding or action to which
the Tenant is a party, with authority to take possession or control of the
Premises or the business conducted thereon by the Tenant and such receiver not
be dismissed within thirty (30) days after his appointment, this Lease, at the
option of the Landlord (a) shall continue in existence as long as (i) the
payment of all Rent agreed to herein is assured, and (ii) that in the event the
Lease is assigned or assumed, no covenants in the Lease will be breached, or (b)
shall immediately end and terminate and shall in no way be treated as an asset
of the Tenant after the exercise of the aforesaid option; and the Landlord shall
have the right, after the exercise of said option, to forthwith re enter the
Premises as its original estate.

        28.  Default.  The occurrence of any of the following shall constitute a
             -------
default by Tenant:

           1. Failure to pay Rent when due;
           2. Abandonment of the Premises; and
           3. Failure to perform any other provision of this Lease.

Notwithstanding anything to the contrary in this Lease, (i) Tenant shall not be
deemed to be in default on account of Tenant' s failure to pay money to
Landlord, unless Tenant's failure to pay continues for five (5) days after
Tenant's receipt of written notice of the delinquency and (ii) Tenant shall not
be in default for failing to perform any covenant of this Lease (other than a
covenant to pay money to Landlord) unless Tenant's failure to perform such
covenant continues for a period of fifteen (15) days after Tenant's receipt of
written notice of such failure, or such longer time as may reasonably be
required to cure the default so long as Tenant commences to cure such failure
within such fifteen (15) day period and diligently prosecutes such cure to
completion.

        In the event of any breach or default of this Lease by the Tenant, then
the Landlord, in addition to any other rights and remedies of the Landlord at
law or equity, shall have the right either to terminate the Tenant's right to
possession of the Premises and thereby terminate this Lease or to have this
Lease continue in full force and effect with the Tenant at all times having the
right to possession of the Premises.

        Should the Landlord elect to terminate the Tenant's right to possession
of the Premises and terminate this Lease, the Landlord shall have the immediate
right of entry and may remove all persons and property from the Premises.  The
Tenant agrees that such property so removed may be stored in a public warehouse

                                      19

 
or elsewhere at the cost and for the account of the Tenant.Upon such
termination, the Landlord shall have all the rights and remedies of a landlord
provided by Article 1951.2 of the Civil Code of the State of California, which
provides that Landlord may recover from Tenant the following: (i) the worth at
the time of the award of the unpaid Rent which had been earned at the time of
termination; (ii) the worth at the time of the award of the amount by which the
unpaid Rent which would have been earned after termination until the time of the
award exceeds the amount of such Rent loss that Tenant proves could have been
reasonably avoided; (iii) the worth at the time of the 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; and (iv) any other amount necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under the Lease or which in the ordinary course of things would be likely to
result therefrom. The "worth at the time of award" of the amounts referred to in
(i) and (ii) of this subsection shall be computed by allowing interest at the
interest rate set forth in paragraph 45 of this Lease. The "worth at the time of
the award" of the amount referred to in (iii) above shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of the award plus one percent (1%).

        As used herein, the term "time of award" shall mean either the date upon
which the Tenant pays to the Landlord the amount recoverable by the Landlord as
hereinabove set forth or the date of entry of any determination, order or
judgment of any court or other legally constituted body, whichever first occurs.
No act by the Landlord other than giving written notice to the Tenant shall
terminate this Lease; acts of maintenance, efforts to relet the Premises or the
Landlord's appointment of a receiver to protect the Landlord's interest shall
not constitute a termination of the Tenant's right to possession.

        Should the Landlord, following any breach or default of this Lease by
the Tenant, elect to keep this Lease in full force and effect, with the Tenant
retaining the right to possession of the Premises (notwithstanding the fact the
Tenant may have abandoned the Premises), then the Landlord, in addition to all
other rights and remedies the Landlord may have at law or equity, shall have the
right to enforce all of the Landlord's rights and remedies under this Lease
including, but not limited to, the right to recover the installments of Rent as
they become due under this Lease.

        Notwithstanding any such election to have this Lease remain in full
force and effect, the Landlord may at any time thereafter elect to terminate the
Tenant's right to possession of the Premises and thereby terminate this Lease
for any previous breach or default which remains uncured, or for any subsequent
breach or default.

        Any and all sums in addition to the Rent payable by the Tenant to the
Landlord pursuant to the provisions of this Lease or arising from the Tenant's
use and occupancy of the Premises shall be deemed additional rent under this
Lease and default by the Tenant in the payment of any such sums (beyond the
applicable cure period) shall entitle the Landlord to all the same remedies as
would be applicable in the case of nonpayment of Rent hereunder.

        29.  Damage or Destruction of Premises.   If, during the term, the
             ---------------------------------
Premises or the Building and other improvements in which the Premises are
located are totally or partially destroyed from any cause, rendering the
Premises totally or partially inaccessible or unusable, and at least one (1)
year of the Lease term remains (or, if Tenant exercises its option to extend the
term of this Lease for the full two (2)year period within fifteen (15) days
after the date of the damage), Landlord shall restore the Premises or the
Building and other improvements in which the Premises are located to
substantially the same condition as they were in immediately before destruction,
if the restoration can be made under the existing laws and can be completed
within 120 working days 

                                      20

 
after the date of the destruction and if thecost of such repairs does not exceed
the amount of insurance proceeds received by Landlord on account of such damages
(or, if Tenant elects to pay the portion of the cost not covered by insurance
proceeds). Such destruction shall not terminate this Lease.

        If the restoration cannot be made in the time stated in this paragraph,
then within 15 days after the Landlord determines that the restoration cannot be
made in the time stated in this paragraph, Tenant can terminate this Lease
immediately] by giving notice to Landlord. If Tenant fails to terminate this
Lease and if restoration is permitted under the existing laws, Landlord, at its
election, can either terminate this Lease or restore the Premises or the
Building and other improvements in which the Premises are located within a
reasonable time and this Lease shall continue in full force and effect. If the
existing laws do not permit the restoration, either party can terminate this
Lease immediately by giving notice to the other party. In the event of the
giving of such notice of termination by the Landlord or the Tenant as provided
herein, this Lease and all interest of the Tenant in the Premises shall
terminate fifteen (15) days after receipt of such notice by the other party.

        Except if Landlord receives insurance proceeds from Tenant's insurance
as provided in paragraph 16(c) hereof, the Landlord shall not be required to
repair any injury or damage, by fire or other cause to the property of the
Tenant, or to make repairs or replacements of any panelings, decorations,
railings, floor coverings or any improvements installed on the Premises by or
for the Tenant.

        In case of destruction, there shall be an abatement or reduction of
Rent, between the date of destruction and the date of completion of restoration
if restoration takes place, based on the extent to which the destruction
interferes with Tenant's use of the Premises.

        The Tenant hereby waives the provisions of Section 1932, Subdivision 2,
and 1933, Subdivision 4, of the Civil Code of California.

        30.  Eminent Domain.  If all or any part of the Building of which the
             --------------
Premises are a part shall be taken or appropriated by any public or quasipublic
authority under any power of eminent domain, the Landlord may terminate this
Lease. In such event, the Landlord shall be entitled to, and the Tenant upon
demand of the Landlord shall assign to the Landlord any rights of the Tenant to
any and all income, rent, award, or any interest therein whatsoever which may be
paid or made in connection with such public or quasipublic use or purpose except
to the extent attributable to Tenant' s trade fixtures and moving expenses, and
the Tenant shall have no claim against the Landlord for the value of any
unexpired term of this Lease. If a part of the Premises shall be so taken or
appropriated and the Landlord does not elect to terminate this Lease, the Rent
thereafter to be paid shall be reduced on a pro rata square footage basis.
Tenant shall have the right to terminate this Lease if all or any part of the
Premises is taken such that such taking renders the Premises unsuitable for
Tenant's use, in Tenant's reasonable opinion.


        31.  Plats and Riders.  Clauses, plats and riders, if any, signed by the
             ----------------
Landlord and the Tenant and endorsed on or affixed to this Lease are a part
hereof and, in the event of variation or discrepancy, the duplicate original
hereof, including such clauses, plats and riders, if any, held by the Landlord
shall control.

        32.  Sale by the Landlord. In the event of a sale or conveyance by the
             --------------------
Landlord of the Building and provided that Landlord delivers the Letter of
Credit or the cash security deposit, as applicable, to the transferee, the same
shall operate to release the Landlord from any future liability upon any of the
covenants or conditions, express or implied, herein contained in favor of the

                                      21

 
Tenant, and in such event the Tenant agrees to look solely to theresponsibility
of the successor in interest of the Landlord in and to this Lease. If any
security is given by the Tenant to secure the faithful performance of all or any
of the covenants of this Lease on the part of the Tenant, the Landlord may
transfer and/or deliver the security, as such, to the successor in interest of
the Landlord, and thereupon the Tenant agrees that the Landlord shall be
discharged from any further liability in reference thereto. Except as set forth
in this paragraph 32, this Lease shall not be affected by any such sale or
conveyance.

        33.  Estoppel Certificates.  At any time and from time to time, upon the
             ---------------------
request by the Landlord, the Tenant agrees to execute, acknowledge and deliver
to the Landlord a statement certifying the date of commencement of this Lease,
stating that this Lease is unmodified and in full force and effect (or if there
have been modifications) and the dates to which the Rent has been paid, and
setting forth such other matters as may be reasonably requested by the Landlord.
The Landlord and the Tenant intend that any such statement delivered pursuant to
this paragraph may be relied upon by any mortgagee or the beneficiary of any
deed of trust or by any purchaser or prospective purchaser of the Building.

        34.  Right of the Landlord to Perform. All covenants and agreements to
             --------------------------------
be kept or performed by the Tenant under any of the terms of this Lease shall be
performed by the Tenant at the Tenant's sole cost and expense and without any
abatement of Rent. If the Tenant shall fail to pay any sum of money, other than
Rent required to be paid by it hereunder, or shall fail to perform any other act
on its part to be performed hereunder, and such failure shall continue for five
(5) days after notice thereof by the Landlord, the Landlord may, but shall not

covenants, conditions, provisions and agreements of this Lease on Tenant ' 5

             ---------
remedy of Landlord on any default by Tenant shall impair such a right or remedy
or be construed as a waiver.

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

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

        Landlord's consent to or approval of any act by Tenant requiring
Landlord's consent or approval must be in writing and such consent or approval
shall not be deemed to waive or render unnecessary Landlord's consent to or
approval of any subsequent act by Tenant.

                                      23

 
         Any waiver by Landlord of any default must also be in writing and shall
not be a waiver of any other default concerning the same or any other provision
of the Lease.

         41.  Notices.  All notices and demands which may or are required to be
              -------
given by Landlord to the Tenant hereunder shall be delivered personally or sent
by United States certified or registered mail, postage prepaid, addressed to the
Tenant at the Premises, Attn: Bruce Runyan, V.P. Operations, or to such other
place as the Tenant may from time to time by like notice designate. All notices
and demands by the Tenant to the Landlord shall be sent by United States
certified or registered mail, postage prepaid, addressed to the Landlord at 2101
Market Street, San Francisco, California, 94114 or to such other place as the
Landlord may from time to time by like notice designate, with a copy sent by
United States registered or certified mail to Bernard J. Schoenberg, Esq., One
California Street, Suite 2424, San Francisco, California, 94111.

         42.  Defined Terms and Marginal Headings.  The words "Landlord" and
              -----------------------------------
"Tenant" as used herein shall include the plural as well as the singular. Words
used in masculine gender include the feminine and neuter. If there is more than
one Tenant, the obligations hereunder imposed upon the Tenant shall be joint and
several. The marginal headings and titles to the paragraphs of this Lease are
not a part of this Lease and shall have no effect upon the construction or
interpretation of any part hereof.

         43.  Time and Applicable Law.  Time is of the essence of this Lease and
              -----------------------
each and all of its provisions. This Lease shall in all respects be governed by
the laws of the State of California.

         44.  Successors.  Except as otherwise provided herein, the covenants
              ----------
and conditions herein contained shall be binding upon and inure to the benefit
of the heirs, successors, executors, administrators and assigns of the parties
hereto.

         45.  Late Charge.  The Tenant acknowledges that late payment by Tenant
              -----------
to Landlord of Rent or other payment required to be made by Tenant to Landlord
under this Lease will cause the Landlord to incur costs not contemplated by this
Lease, the exact amount of such costs being extremely difficult and
impracticable to fix. Such costs include, without limitation, processing and
accounting charges, and late charges that may be imposed on the Landlord by the
terms of any encumbrance or note secured by any encumbrance covering the
Premises or Property. Therefore, if any installment of Rent due from the Tenant
or other payment required to be made by Tenant to Landlord is not received by
Landlord when due, the Tenant agrees to pay to Landlord interest at the rate of
10% per annum from the date the Rent or any other payment is due until receipt
by Landlord of the Rent or other payment. The parties agree that this late
charge represents a fair and reasonable estimate of the costs that the Landlord
will incur by reason of late payment by the Tenant. Acceptance of any late
charge shall not constitute a waiver of the Tenant's default with respect to the
overdue amount, nor prevent the Landlord from exercising any of the other rights
and remedies available to the Landlord.

         46.  Authority.   If Tenant is a corporation,  partnership,  trust,
              ---------
association or other entity, Tenant and each person executing this Lease on
behalf of Tenant does hereby covenant and warrant that (a) Tenant is duly
incorporated or otherwise established or formed and validly existing under the
laws of its state of incorporation, establishment or formation, (b) Tenant has
and is duly qualified to do business in California, (c) Tenant has full
corporate, partnership, trust, association or other appropriate power and
authority to enter into this Lease and to perform all Tenant's obligations
hereunder, and (d) each person (and all of the persons if more than one signs)
signing this Lease on behalf of Tenant is duly and validly authorized to do so.

                                      24

 
        47.  Name of Building.  Tenant shall not use the name of the Building
             ----------------
without the Landlord's consent. Tenant shall not have or acquire any property
right or interest in the name of the Building.

        48.  Entire Agreement.  This Lease constitutes the entire agreement
             ----------------
between the Landlord and the Tenant, and no promises or representations, express
or implied, either written or oral, not herein set forth shall be binding upon
or inure to the benefit of the Landlord or the Tenant. This Lease shall not be
modified by any oral agreement, either express or implied, and all modifications
hereof shall be in writing and signed by both the Landlord and the Tenant.

        49.  No Offer.   Submission of this instrument for examination or
             --------
signature by Tenant does not constitute a reservation of or option for lease and
it is not effective as a lease or otherwise until execution and delivery by both
Landlord and Tenant.

        50.  Exhibits and Additional Provisions.  The Exhibits designated as A
             ----------------------------------
