                                     LEASE

        This Lease is made and entered into as of the "Date of Lease", by and
between "Landlord" and "Tenant", as those terms are defined in the "Lease
Summary", which Lease Summary is attached to the front of and incorporated in
and made part of this Lease.

        1. Premises.

               1.1 Description of Premises. Landlord leases the "Premises" (as
hereinafter defined) to Tenant, and Tenant leases the Premises from Landlord for
the Term, at the rental, and upon all of the conditions set forth herein and in
the Lease Summary. The Premises consist of the space described in the Lease
Summary, and shown on the plans attached as Exhibits A-1 and A-2. The Premises,
the Building and the land on which the Building and the Premises are located are
referred to collectively as the "Property". Tenant accepts the Premises as being
the square footage set forth in the Lease Summary.

               1.2 Condition of Premises. By taking possession of the Premises,
Tenant shall be deemed to have accepted the Premises, the Building and the
Property in their condition existing as of the date of possession. Tenant waives
all rights to make repairs at the expense of Landlord as provided by any law,
rule or regulation now or hereafter in effect. It is specifically understood and
agreed that, except as specifically set forth in this Lease, Landlord has no
obligation and has made no promises to alter, remodel, improve, repair, decorate
or paint the Premises or any part thereof, and that no representations
respecting the condition of the Premises or the Building have been made by
Landlord to Tenant.

               1.3 Ground Lease. This Lease is subject and subordinate to the
terms and provisions of that certain Master Lease dated as of January 21, 1994,
by and between Dale H. Denson and Nancy Steele Denson, Tommie W. Flemming and
Betty N. Flemming, and Jack R. Rominger and Mary Frances Rominger collectively,
as lessor, and 505 Hamilton Avenue Partners, as lessee.

        2. Term.

               2.1 Subject to the provisions of this Lease, the term of this
Lease (hereinafter referred to as the "Term") shall commence on the Commencement
Date (specified in the Lease Summary), and, unless sooner terminated pursuant
to the terms hereof or at law, shall expire on the Expiration Date (specified in
the Lease Summary).

               2.2 The Premises shall be delivered to Tenant upon Substantial
Completion (as that term is defined in Exhibit B) of the Tenant Improvements (as
that term is defined in Exhibit B) to be constructed in the Premises by Landlord
pursuant to Exhibit B. If Substantial Completion of the Tenant Improvements and
delivery of possession of the Premises is delayed for any reason whatsoever,
this Lease shall not be void or voidable. Except as otherwise provided herein,
no delay in delivery of possession of the Premises to Tenant shall operate to
extend the Term or amend Tenant's obligations under this Lease. In no event
shall Landlord be liable to Tenant for any delay in completion of the Tenant
Improvements caused or occasioned by strikes, lockout, labor disputes, shortages
of material or labor, fire or other casualty, acts of God or any other cause
beyond the reasonable control of Landlord.

<PAGE>   8

                  (i)   The term "Tax Expenses" shall mean all taxes,
assessments (whether general or special), excises, transit charges, housing
fund assessments or other housing charges, improvement districts, levies or
fees, ordinary or extraordinary, unforeseen as well as foreseen, of any kind,
which are assessed, levied, charged, confirmed or imposed on the Building or
the Property, on Landlord with respect to the Property, on the act of entering
into leases of space in the Property, on the use or occupancy of the Property
or any part thereof, with respect to services or utilities consumed in the use,
occupancy or operation of the Property, on any improvements, fixtures and
equipment and other personal property of Landlord located in the Property and
used in connection with the operation of the Property, or on or measured by the
rent payable under this Lease or in connection with the business of renting
space in the Property, including, without limitation, any gross income tax or
excise tax levied with respect to the receipt of such rent, by any state,
county, city or political subdivision, public corporation, district or other
political or public entity or public authority, and shall also include any
other tax, fee or other excise, however described, which may be levied or
assessed in lieu of, as a substitute (in whole or in part) for, or as an
addition to, any other Tax Expense. Tax Expenses shall include reasonable
attorneys' fees, costs and disbursements incurred in connection with
proceedings to contest, determine or reduce Tax Expenses. If it shall not be
lawful for Tenant to reimburse Landlord for any increase in Tax Expenses as
defined herein, the Rent payable to Landlord prior to the imposition of such
increases in Tax Expenses shall be increased to net Landlord the same net Rent
after imposition of such increases in Tax Expenses as would have been received
by Landlord prior to the imposition of such increases in Tax Expenses.

                  (ii)  Tax Expenses shall not include income, franchise,
transfer, inheritance or capital stock taxes, unless, due to a change in the
method of taxation, any of such taxes is levied or assessed against Landlord in
lieu of, as a substitute (in whole or in part) for, or as an addition to, any
other charge which would otherwise constitute a Tax Expense.

            (c)   Adjustment for Occupancy Factor. Notwithstanding any other
provision herein to the contrary, in the event the Building is not at least one
hundred percent (100%) occupied on average during any year of the Term, an
adjustment shall be made by Landlord in computing Operating Expenses and Tax
Expenses for such year so that the Operating Expenses and Tax Expenses shall be
computed for such year as though the Building had been one hundred percent
(100%) occupied on average during such year. In addition, if any particular
work or service includable in Operating Expenses is not furnished to a tenant
who has undertaken to perform such work or service itself, Operating Expenses
shall be deemed to be increased by an amount equal to the additional Operating
Expenses which would have been incurred if Landlord had furnished such work or
service to such tenant. The parties agree that statements in this Lease to the
effect that Landlord is to perform certain of its obligations hereunder at its
own or sole cost and expense shall not be interpreted as excluding any cost
from Operating Expenses or Tax Expenses if such cost is an Operating Expense or
Tax Expense pursuant to the terms of this Lease.

            (d)   [INTENTIONALLY OMITTED]

            (e)   Notice and Payment. On or before the first day of each
calendar year following the Base Year, on as soon as practicable thereafter,
Landlord shall give to Tenant notice of Landlord's estimate of the Additional
Rent, if any, payable by Tenant pursuant to



                                       4
<PAGE>   9

Paragraphs 3.2(a) and 3.2(b) for such calendar year. On or before the first day
of each month during each such calendar year, Tenant shall pay to Landlord
one-twelfth (1/12th) of the estimated Additional Rent; provided, however, that
if Landlord's notice is not given prior to the first day of any calendar year
Tenant shall continue to pay Additional Rent on the basis of the prior year's
estimate until the month after Landlord's notice is given. If at any time it
appears to Landlord that the Additional Rent payable under Paragraphs 3.2(a)
and/or 3.2(b) will vary from Landlord's estimate, Landlord may, by written
notice to Tenant, revise its estimate for such year, and subsequent payments by
Tenant for such year shall be based upon the revised estimate. On the first
monthly payment date after any new estimate is delivered to Tenant, Tenant shall
also pay any accrued cost increases, based on such new estimate.

                    (f) Annual Accounting. Within ninety (90) days after the
close of each calendar year, or as soon after such ninety (90) day period as
practicable, Landlord shall deliver to Tenant a statement of the Additional Rent
payable under Paragraphs 3.2(a) and 3.2(b) for such year. Landlord's annual
statement shall be final and binding upon Landlord and Tenant unless either
party, within thirty (30) days after Tenant's receipt thereof, shall contest any
item therein by giving written notice to the other, specifying in reasonable
detail each item contested and the reason therefor. Notwithstanding the
foregoing, the Tax Expenses included in any such annual statement may be
modified by any subsequent adjustment or retroactive application of Tax Expenses
affecting the calculation of such Tax Expenses. If the annual statement shows
that Tenant's payments of Additional Rent for such calendar year pursuant to
Paragraph 3.2(e) hereof exceeded Tenant's obligations for the calendar year,
Landlord shall at its option either (1) credit the excess to the next succeeding
installments of estimated Additional Rent or (2) pay the excess to Tenant within
thirty (30) days after delivery of such statement. If the annual statement shows
that Tenant's payments of Additional Rent for such calendar year pursuant to
Paragraph 3.2(e) hereof were less than Tenant's obligation for the calendar
year, Tenant shall pay the deficiency to Landlord within ten (10) days after
delivery of such statement.

               3.3 Late Payment Charge interest. If any installment of Rent,
Additional Rent or any other sum due from Tenant is not received by Landlord,
Tenant shall pay to Landlord as liquidated damages an additional sum equal to
five percent (5%) of the amount overdue to compensate Landlord for reasonably
foreseeable processing and accounting charges, and any charges that may be
incurred by Landlord with regard to any financing secured by the Property.
Acceptance of any late charge shall not constitute a waiver by Landlord of
Tenant's default with respect to the overdue amount. In addition, any amount not
paid by Tenant shall bear interest at the lower of five percent (5%) per annum
plus the then discount rate of the Federal Reserve Bank of San Francisco, or the
highest rate then allowed by law (such lower rate is referred to herein as the
"Interest Rate"), from the date due until paid in full. Payment of such interest
shall not excuse or cure any default by Tenant.

               3.4 Security Deposit. Tenant shall pay to Landlord upon execution
of this Lease the amount set forth in the Lease Summary as and for a Security
Deposit as security for the full and faithful performance by Tenant of every
term, covenant and condition of this Lease. In the event Tenant defaults in the
performance of any of its obligations hereunder, Landlord may use or apply any
portion of the Security Deposit to cure the default or to compensate Landlord
for its damages from the default, in which event Tenant shall promptly deposit
with Landlord the sum necessary to restore the Security Deposit to its original
amount. Upon



                                       5
<PAGE>   10

termination of this Lease and performance of all of Tenant's obligations
hereunder, Landlord shall return the Security Deposit or any balance thereof to
Tenant. Tenant shall not be entitled to any interest on the Security Deposit,
and Landlord shall be entitled to commingle the Security Deposit with its
general funds.

        4. Use.

               4.1 Use of the Premises. The Premises shall be used only for the
use described in the Lease Summary as the "Permitted Use" and for no other
purpose. Tenant will engage in no activity on the Premises that would, in the
judgment of any insurer of the Premises, increase the premium on any of
Landlord's insurance over the amount otherwise charged therefor or cause such
insurance to be canceled. Tenant will comply with all applicable laws and
governmental regulations pertaining to its use of the Premises; provided that if
such compliance requires that Alterations (as defined in Paragraph 5) be made to
any portion of the Building or Premises, Tenant shall have no obligation to make
any such Alteration unless such Alteration is necessitated by Tenant's
particular use of the Premises. Tenant will not cause any excessive loads to be
placed upon the floor slabs or the walls of the Premises by the placement of its
furnishings or equipment or otherwise. Tenant will commit no nuisance or waste
on the Premises and will not cause any unreasonable odors, noise, smoke,

<PAGE>   13

use of the Premises or an assignment of this Lease or a sublease of all or a
portion of the Premises (collectively herein a ("Use Change") if such Use Change

the Premises, the common areas or other portions of the Building, or the
acquisition of any auxiliary aids under the ADA, unless Tenant performs all such
acts and satisfies Landlord's requirements for financial responsibility for the
costs of such compliance, which requirements may include, by way of example,
posting of a completion bond or establishment of an escrow account.

        5. Alterations and Additions.

           5.1 Landlord's Consent Required. Tenant shall not make any alteration
or addition (collectively "Alterations") to the Premises without Landlord's
prior written consent which may be withheld in Landlord's sole and absolute
discretion. Notwithstanding the immediately preceding sentence, Tenant shall
have the right without Landlord's approval to make minor Alterations within the
interior of the Premises that do not affect the structure of the Building, the
Building Systems, the exterior of the Building or Landlord's ability to lease
the Premises following the expiration of the Term, provided that (i) such
Alterations do not exceed Two Thousand Five Hundred Dollars ($2,500) in cost per
project; (ii) prior to commencing such Alterations, Tenant shall give written
notice to Landlord specifying the work to be done and the area of the Premises
affected by such work; and (iii) Tenant shall obtain all necessary governmental
permits and approvals prior to commencing such work. In making any Alterations
hereunder, Tenant shall comply with all applicable building codes and other
Legal Requirements. In connection with giving its consent to a requested
Alteration, Landlord shall notify Tenant that such Alteration either (i) shall
be removed from the Premises, and all damage resulting from such removal
repaired by Tenant prior to the expiration or sooner termination of the Term, or
(ii) shall remain on the Premises at the end of the Term and become the property
of the Landlord. Tenant shall not proceed to make any Alterations until ten (10)
days after receipt of Landlord's written consent, in order that Landlord may
post on the Premises appropriate notices to avoid any liability or liens by
reason thereof.

           5.2 Performance of Work. All Alterations shall be made at Tenant's
sole cost and expense (including the expense of complying with all present and
future Legal Requirements, and any other work required to be performed in other
areas within or outside the Premises by reason of the Alterations). Landlord may
elect to cause its contractor to perform the Alterations, in which case Landlord
shall be entitled to receive a fee for such work of fifteen percent (15%) of the
first $100,000 of the construction costs of such work, and five percent (5%) of
any construction costs over $100,000. If Landlord does not perform the work
pursuant to the above, Tenant shall pay Landlord on demand prior to or during
the course of such construction an amount (the "Alteration Operations Fee")
equal to ten percent (10%) of the total hard cost of the Alteration (and for
purposes of calculating the Alteration Operations Fee, such hard cost shall not
include permit fees) as compensation to Landlord for electrical energy consumed
in connection with the work, freight elevator operation, additional cleaning
expenses, additional security services, and for other miscellaneous costs
incurred by Landlord as result of the work.

<PAGE>   14

        6. Liens. Tenant shall not permit any mechanic's, materialman's or other
liens arising out of work performed at the Premises by or on behalf of Tenant to
be filed against the fee of the Property nor against Tenant's interest in the
Premises. Landlord shall have the right to post and keep posted on the Premises
any notices which it deems necessary for protection from such liens. If any such
liens are filed, Landlord may, without waiving its rights based on such breach
by Tenant and without releasing Tenant from any obligations hereunder, pay and
satisfy the same and in such event the sums so paid by Landlord shall be due and
payable by Tenant immediately without notice or demand, with interest from the
date paid by Landlord through the date Tenant pays Landlord, at the Interest
Rate. Tenant agrees to indemnify, defend and hold Landlord harmless from and
against any claims, loss, cost, damage or liability for mechanics',
materialmen's or other liens in connection with any Alterations, repairs or any
work performed, materials furnished or obligations incurred by or for Tenant.

        7. Maintenance and Repair.

           7.1 Tenant's Obligations. Except for those portions of the Building
which Landlord is expressly obligated to maintain and repair pursuant to
Paragraph 7.2 below, Tenant, at its sole cost, shall maintain in first class
condition and repair the non-structural portions of the Premises and every part
thereof, including, if applicable any plate glass (other than exterior office
space windows on floors above the ground floor). If Tenant refuses or neglects
to make repairs and/or maintain the Premises, or any part thereof, in a manner
and within a time period reasonably satisfactory to Landlord, Landlord shall
have the right, upon giving Tenant reasonable written notice of its election to
do so, to make such repairs or perform such maintenance on behalf of and for the
account of Tenant. In such event the cost of such work (including a fee payable
to Landlord for the performance of such work as outlined in Paragraph 5.2 above)
shall be paid by Tenant promptly upon Landlord's presentation of reasonable
evidence of the costs actually incurred.

           7.2 Landlord's Obligations. Subject to Tenant's obligations pursuant
to Paragraph 7.1, and the provisions of this Lease dealing with damage or
destruction and condemnation, Landlord shall, as part of Operating Expenses,
repair and maintain in good working order the roof, roof membrane, and all
structural portions of the Premises and the Building, the heating, ventilation,
air-conditioning, plumbing and electrical systems and other equipment serving
the Premises (but not to the extent any such system or any life systems
installed by or on behalf of Tenant exclusively serve the Premises) (the
"Building Systems"), the elevators, common areas, exterior surfaces or the
Building (except with respect to plate glass which is the responsibility of
Tenant pursuant to the terms of Paragraph 7.1 above), sidewalks, the parking lot
and landscaping for the Building. Tenant hereby waives the benefit of any
statute now or hereinafter in effect which would otherwise afford Tenant the
right to make repairs at Landlord's expense or to terminate this Lease because
of Landlord's failure to keep the Premises in good condition, order and repair.
Tenant specifically waives all rights it may have under Sections 1932(l), 1941,
and 1942 of the California Civil Code, and any similar or successor statute or
law.

        8. Tenant's Personal Property Taxes. Tenant shall pay prior to
delinquency all taxes, license fees, and public charges assessed or levied
against Tenant, Tenant's estate in this




                                       10
<PAGE>   15


Lease or Tenant's leasehold improvements, trade fixtures, furnishings, equipment
and other Personal property,

        9. Utilities and Services.


           9.1 Basic Services. As part of Operating Expenses (except as set
forth in Paragraph 9.2 below), and provided Tenant is not in default hereunder,
Landlord shall furnish the following utilities and services ("Basic: Services")
for the Premises:

               (i) during the Business Hours specified in the Lease Summary
reasonable quantities of electricity for lighting and convenience outlets;

               (ii) during Business Hours, heat and air conditioning required in
Landlord's judgment for the comfortable use and occupancy of the Premises for
ordinary general office purposes;


               (iii)unheated water for the restroom(s) and drinking fountain(s)
in the public areas serving the Premises; and

               (iv) janitorial services limited to emptying and removal of
general office refuse, light vacuuming as needed and window washing, all as
determined by Landlord,

Notwithstanding the foregoing, however, Tenant may use water, heat, air
conditioning, electric current, elevator and janitorial service in excess of
that provided in Basic Services ("Excess Services") which shall include without
limitation any power usage other than through existing standard 110-volt AC
outlets, electricity and/or water consumed by Tenant in connection with any
dedicated or supplemental heating, ventilating and/or air conditioning, computer
power, telecommunications and/or other special units or systems of Tenant,
chilled, heated or condenser water, or water used for any purpose other than
ordinary drinking and lavatory purposes, provided that the Excess Services
desired by Tenant are reasonably available to Landlord and to the Premises, and
provided further that Tenant complies with the procedures established by
Landlord from time to time for requesting for such Excess Services and with all
other provisions of this Paragraph 9. Tenant shall pay for such Excess Services
at the hourly rate established by Landlord, which shall include Landlord's
then-standard administrative charge; the parties agree that Landlord's charge
for after hours heating or air conditioning shall be $25.00 per hour. Landlord
reserves the right, at Tenant's cost, to install in the Premises electric
current and/or water meters (including, without limitation, any additional
wiring, conduit or panel required therefor) to measure the electric current or
water consumed by Tenant or to cause the usage to be measured by other
reasonable methods (e.g. by temporary "check" meters or by survey). If the
temperature otherwise maintained in any portion of the Premises by the HVAC
systems of the Building is affected as a result of (i) any lights, machines or
equipment used by Tenant in the Premises, or (ii) the occupancy of the Premises
by more than one person per 200 square feet of rentable area, then Landlord
shall have the right to install any machinery or equipment reasonably necessary
to restore the temperature, including modifications to the standard
air conditioning equipment. The cost of any such equipment and modifications,
including the cost of installation and any additional cost of operation and
maintenance of the same, shall be paid by Tenant to Landlord upon demand.




                                       11
<PAGE>   16

           9.2 Payment. The cost of any services which are not separately
metered and payable for directly by Tenant shall be included in Operating
Expenses. If any such services are, however, separately metered, Tenant shall
pay directly to the charging authority for all costs of providing Basic Services
to the Premises including, all charges for water, gas, electricity, refuse
pickup, and all other utilities and services supplied or furnished to the
Premises which are separately metered to the Premises, and the costs of such
services will be excluded from Operating Expenses.

           9.3 Failure. No failure or interruption of any such utilities or
service shall entitle Tenant to terminate this Lease or to withhold rent or
other sums due hereunder and Landlord shall not be liable to Tenant for any such
failure or interruption.

           9.4 Security. Landlord may, but shall be under no obligation to,
implement security measures for the Building, such as the registration of all
persons entering or leaving the Building, requiring identification for access to
the Building, evacuation of the Building for cause, suspected cause, or for
drill purposes, the issuance of magnetic pass cards or keys for Building or
elevator access and other actions that Landlord deems necessary or appropriate
to prevent any threat of property loss or damage, bodily injury or business
interruption. landlord shall at all times have the right to change, alter or
reduce any such security services or measures. Tenant shall cooperate and comply
with, and cause Tenant's Representatives and Visitors to cooperate and comply
with, such security measures. Landlord, its agents and employees shall have no
liability to Tenant or its representatives or visitors for the implementation or
exercise of, or the failure to implement or exercise, any such security measures
or for any resulting disturbance of Tenant's use or enjoyment of the Premises,
and Tenant, on behalf of Tenant, its employees and representatives waives all
claims against Landlord with regard thereto.

        10. Indemnity. To the fullest extent allowed under applicable law,
Tenant hereby agrees to indemnify, defend, protect and hold Landlord harmless
from and against any and all claims, losses, demands, liabilities, and expenses,
including attorneys' fees, arising from (a) Tenant's use of the Premises or (b)
from any act permitted, or any omission to act, in or about the Premises or (c)
the Property by Tenant or its agents, employees, contractors, representatives,
visitors or invitees, or from any breach or default by Tenant of this Lease, or
(d) from any injury to person or property occurring in or about the Premises,
unless solely caused by Landlord's gross negligence or willful misconduct. In
the event any action or proceeding shall be brought against Landlord by reason
of any such claim, Tenant shall defend the same at Tenant's expense by counsel
reasonably satisfactory to Landlord. The obligations of Tenant under this
Paragraph 10 shall survive the expiration or sooner termination of this Lease.

        11. Waiver of Claims. Tenant hereby waives any claims against Landlord
for damage to Tenant's property, or for injury or death of any other person
in or about the Premises or the Property from any cause whatsoever, except to
the extent caused by Landlord's gross negligence or willful misconduct.

        12. Insurance.

            12.1 Tenant's Liability Insurance. Tenant shall, at its expense,
obtain and keep in force during the Term a policy of commercial public liability
insurance insuring Landlord and



                                       12
<PAGE>   17


Tenant against any liability arising out of the operation of Tenant's business
and the condition, use, occupancy or maintenance of the Premises. Such insurance
policy shall have a combined single limit for both bodily injury and property
damage in an amount not less than Two Million Dollars ($2,000,000). The policy
shall contain cross liability endorsements (to the extent available on
commercially reasonable terms) and shall insure performance by Tenant of the
indemnity provisions of Paragraph 10 above. The limits of said insurance shall
not limit the liability of Tenant hereunder.

            12.2 Tenant's Property Insurance. Tenant shall, at its expense, keep
in force during the term of this Lease, a policy of fire and property damage
insurance, in an "all risk" form, insuring, for their full replacement cost,
Tenant's inventory, fixtures, equipment, personal property, any leasehold
improvements (including the Tenant Improvements) and any Alterations made by
Tenant. Tenant also shall obtain and maintain business interruption insurance in
an amount not less than an amount adequate to provide for payment of Base Rent
and other amounts due Landlord under this Lease during a one year interruption
of Tenant's business due to fire or other casualty, During the Term, the
proceeds from any such policies of insurance shall be used for the repair or
replacement of the leasehold improvements, alterations and personal property so
insured. Because Tenant must maintain property insurance pursuant to this
Paragraph 12.2 to cover Tenant's inventory, fixtures, equipment, personal
property, and any leasehold improvements within the Premises, and because of the
waivers of subrogation set forth in Paragraph 12.5, Tenant hereby waives all
claims against Landlord for any loss, cost, liability, damage, or expense to
Tenant's inventory, fixtures, equipment, personal property, and leasehold
improvements within the Premises to the extent such loss, costs, liability,
damage, or expenses are covered (or would have been covered) by the insurance
carried (or required to be carried) by Tenant pursuant to this Paragraph 12.2,
even if such loss, cost, liability, damage, or expense results from the
negligent acts, omissions, or willful misconduct of Landlord or those of its
agents, contractors, servants, employees or licensees.

            12.3 Landlord's Insurance. Landlord shall, as part of Operating
Expenses, maintain a policy or policies of liability insurance and of insurance
covering loss or damage to the Property (which may, at Landlord's option,
include earthquake) in such amounts and with such coverages as Landlord deems
advisable. All proceeds under such policies shall be payable exclusively to
Landlord. Landlord may obtain such insurance for the Building separately, or
together with other buildings and improvements which Landlord elects to insure
together under blanket policies of insurance.

            12.4 Waiver of Subrogation. Tenant and Landlord each hereby waives,
and shall cause their respective insurers to similarly waive, any and all rights
of recovery against the other, or against the officers, employees, partners,
agents and representatives of the other, for loss of or damage to the property
of the waiving party or the property of others under its control, to the extent
such loss or damage is (or would have been) insured against under any property
insurance policy carried (or required to be carried) by Landlord or Tenant
hereunder.

            12.5 Insurance Policies. All of Tenant's insurance shall be primary
insurance written in a form satisfactory to Landlord by companies acceptable to
Landlord and shall specifically provide by endorsements reasonably acceptable to
Landlord that such policies shall: (i) not be subject to cancellation or other
change except after at least thirty (30) days' prior



                                       13
<PAGE>   18

written notice to Landlord; (ii) be Primary insurance, (iii) in the case of
property insurance, specifically waive subrogation pursuant to this Lease.
Insurance companies issuing such policies shall have rating classifications of
"A" or better and financial size category ratings of "VII" or better according
to the latest edition of the A.M. Best Key Rating Guide. All insurance companies
issuing such policies shall be licensed to do business in the state where the
Property is located. Any deductible amount under such insurance shall not exceed
$5,000. Each policy of liability insurance required by this Section shall: (i)
contain a cross liability endorsement or separation of insureds clause; (ii)
provide that any rights or release prior to a loss does not void coverage; (iii)
provide that it is primary to and not contributing with, any policy of insurance
carried by Landlord covering the same loss; (iv) provide that any failure to
comply with the reporting provisions shall not affect coverage provided to
Landlord, its partners, property managers and Mortgagees; and (v) name Landlord,
its partners, Landlord's property manager, and such other parties in interest as
Landlord may from time to time reasonably designate to Tenant in writing, as
additional insureds. Such additional insureds shall be provided the same extent
of coverage as provided to Tenant under such policies. All endorsements
effecting such additional insured status shall be acceptable to Landlord. Copies
of the policies or certificates evidencing the policies shall be deposited with
Landlord on or prior to the Commencement Date, and upon each renewal of such
policies, which shall be effected not less than thirty (30) days prior to the
expiration date of the term of such coverage. Reasonably satisfactory evidence
of payment of policy premiums shall be provided to Landlord upon request.

            12.6 Adjustment. Tenant shall increase the amounts of insurance as
required by any mortgagee, and, not more frequently than once every year, as
recommended by Landlord's insurance broker, if, in the opinion of either of
them, the amount of insurance then required under this Lease is not adequate.
Any limits set forth in this Lease on the amount or type of coverage required by
Tenant's insurance shall not limit the liability of Tenant under this Lease.

        13. Damage.

            13.1 Generally. Except as otherwise provided in this Paragraph 13,
if any portion of the Premises or Building that Landlord is obligated to
maintain is damaged or destroyed by any cause, and if such damage is covered by
insurance maintained by Landlord, then this Lease will not terminate and
Landlord will cause such damage to be repaired with reasonable diligence,
subject to delays in the obtaining and disbursement of insurance proceeds and
delays in repair caused by inclement weather, governmental action or inaction,
and shortage of materials or services and any other cause beyond the reasonable
control of Landlord. From the date of the casualty until the restoration is
completed, Tenant's obligation to pay Base Rent and Additional Rent shall not be
abated to the extent required to be insured under Paragraph 12 above; any
abatement thereafter allowed shall be determined by Landlord with respect to the
extent to which Tenant is prevented from using and actually does not use, the
Premises. If the damage is not insured by Landlord, or if the damage occurs
within the last nine (9) months of the term of this Lease, or if, in Landlord's
determination, the damage would take in excess of one hundred eighty (180) days
to repair, Landlord may, at its option exercised by written notice to Tenant,
elect to terminate this Lease as of the date set forth in Landlord's notice. If
Landlord does not elect to terminate this Lease, Landlord shall complete the
repair. If the damage is such that Tenant's use of or access to the Premises is
substantially impaired, and if Landlord



                                       14
<PAGE>   19

reasonably estimates that the time required for repair of the Premises will
exceed one (1) year, then Tenant shall be entitled to terminate this Lease as of
the date set forth in Tenant's notice (which shall be no more than Sixty (60)
days following Tenant's notice) by delivering written notice of termination to
Landlord within ten (10) days of Landlord's notice) to Tenant of the time
required for repair.

            13.2 Tenant's Property. Landlord's obligation to rebuild or restore
shall not include Tenant's trade fixtures, equipment, merchandise, or any
improvements or Alterations made by or on behalf of Tenant to the Premises.

            13.3 Waiver. Tenant waives the provisions Of California Civil Code
Sections 1932(2) and 1933(4), and any similar or successor statutes relating to
termination of leases in the event of damage or destruction, and agrees that
the parties, rights and obligations in such event shall instead be governed by
this Lease.

        14. Condemnation. If any part of the Building or Premises shall be taken
for any public, or quasi-public use, under any statute or by right of eminent
domain or purchase in lieu thereof, either Landlord or Tenant shall have the
right to terminate this Lease by written notice delivered within forty-five (45)
days of such taking, provided that Tenant's exercise shall be conditioned upon
the Premises, as existing following such taking, not being fit for the conduct
of Tenant's business. If neither party terminates the Lease, this Lease shall,
as to the part so taken, terminate as of the date title shall vest in the
condemnor or purchaser, and the rent payable hereunder shall be adjusted so that
Tenant shall be required to pay for the remainder of the Term only such portion
of such Rent as the value of the part of the Premises remaining after such
taking bears to the value of the entire Premises prior to such taking. All
compensation awarded upon any taking hereunder shall belong exclusively to the
Landlord. Notwithstanding any provision to the contrary contained herein, Tenant
shall have the right to make a separate claim against the appropriate
governmental authority for condemnation proceeds allocable to the unamortized
costs of the leasehold improvements made at the cost of Tenant, the removal of
Tenant's trade fixtures or removable personal property, and relocation expenses
if and only to the extent that such separate claim does not diminish Landlord's
condemnation award.

        15. Advertisements and Signs. Tenant shall not place or maintain any
sign, advertisement, notice or other marking whether temporary or permanent in
nature upon or about the Premises.

        16. Assignment and Subletting.

            16.1 Landlord's Consent Required. Tenant shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Tenant's interest in this Lease or in the Premises,
without Landlord's prior written consent, which shall not be unreasonably
withheld. Without limiting the grounds upon which Landlord may withhold its
consent, the parties hereto agree that it shall be reasonable for Landlord to
deny consent to a proposed assignment or subletting if (a) the use to be made of
the Premises by the proposed assignee or sublessee is not the Permitted Use or
would be prohibited by any other term of this Lease; (b) the character,
reputation and financial condition of the proposed assignee or sublessee are not
satisfactory to Landlord; (c) the assignment or subletting would



                                       15
<PAGE>   20

increase the operating costs for the Building or the burden on the Building
services, or generate additional foot traffic, elevator usage or security
concerns in the Building, or create an increased probability of the comfort
and/or safety of Landlord and other tenants in the Building being Compromised or
reduced; (d) the space will be used for a school or training facility, an
entertainment, sports or recreation facility, retail sales to the public (unless
Tenant's Permitted Use is retail sales), a personnel or employment agency, an
office or facility of any governmental or quasi-governmental agency or
authority, a place of public assembly (including without limitation a meeting
center, theater or public forum), any use by or affiliation with a foreign
government (including without limitation an embassy or consulate or similar
office, or a facility for the provision of social, welfare or clinical health
services or sleeping accommodations (whether temporary, daytime or overnight);
(e) the proposed assignee or subtenant is a current tenant in the Building or a
prospective tenant of the Building; (f) the proposed assignee or subtenant is an
entity or related to an entity with whom Landlord or any affiliate of Landlord
has had adverse dealings; (g) the proposed assignment or subletting may conflict
with any exclusive uses granted to other tenants of the Building, or with the
terms of any easement, covenant, condition or restriction, or other agreement
affecting the Building; (h) Landlord determines that the proposed assignee may
be unable to perform all of Tenant's obligations under this Lease or the
proposed subtenant may be unable to perform all of its obligations under the
proposed sublease; (i) the rental and other consideration payable by the
proposed subtenant or assignee is less than that currently being paid by tenants
under new leases of comparable space in the Building; or (j) Landlord otherwise
determines that the proposed assignment or sublease would have the effect of
decreasing the value of the Building or increasing the expenses associated with
operating, maintaining and repairing the Building. In no event may Tenant
publicly offer or advertise all or any portion of the Premises for assignment or
sublease at a rental less than that then sought by Landlord for a direct lease
(non-sublease) of comparable space in the Building. Notwithstanding the
foregoing, Tenant may assign this Lease at any time, or sublease all or part of
the Premises, without receipt of Landlord's consent (but with prior notice to
Landlord establishing that the conditions set forth in this sentence have been
complied with), to any entity which acquires all or part of Tenant, or which is
acquired in whole or in part by Tenant, or which is controlled directly or
indirectly by Tenant, or which is under common control with Tenant, or which
entity controls, directly or indirectly, Tenant ("Affiliate"), or which owns or
is owned by the Affiliate, so long as such Affiliate has a net worth, as
confirmed by Landlord, equal to or in excess of the greater of (A) the net worth
of Tenant as of the date of this Lease and (B) the net worth of Tenant
immediately prior to such proposed assignment or sublease.

            16.2 Transactions Constituting Transfers Governed by this Paragraph
16. For purposes of this Paragraph 16, and without limited the events which
might constitute an assignment of this Lease or a sublease of Tenant's interest
hereunder, the following events shall be deemed an assignment or sublease, as
appropriate: (i) the issuance of equity interests (whether stock, partnership
interests or otherwise) in Tenant or any subtenant or assignee, or any entity
controlling any of them, 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 (as defined
below) of Tenant or any subtenant or assignee; (ii) a transfer of Control of
Tenant or any subtenant or assignee, or any entity controlling any of them, in a
single transaction or a series of related or unrelated transactions (including,
without limitation, by consolidation, merger, acquisition or reorganization),
except



                                       16
<PAGE>   21
that the transfer of outstanding capital stock or other listed equity interests
by persons or parties other than "insiders" within the meaning of the Securities
Exchange Act of 1934, as amended, through the "over-the-counter" market or any
recognized national or international securities exchange, shall not be included
in determining whether Control has been transferred; (iii) a reduction of
Tenant's assets to the point that this Lease is substantially Tenant's only
asset; (iv) a change or conversion in the form of entity of Tenant, any
subtenant or assignee, or any entity controlling any of them, which has the
effect of limiting the liability of any of the partners, members or other owners
of such entity; or (v) the agreement by a third party to assume, take over, or
reimburse Tenant for, any or all of Tenant's obligations under this Lease, in
order to induce Tenant to lease space with such third party. "Control" shall
mean direct or indirect ownership of 50% or more of all of the voting stock of a
corporation or 50% or more of the legal or equitable interest in any other
business entity, or the power to direct the operations of any entity (by equity
ownership, contract or otherwise).

            16.3 Effect on Options. If Landlord approves of an assignment or
subletting hereunder and this Lease contains any renewal options, expansion
options, rights of first refusal, rights of first negotiation or any other
rights or options pertaining to additional space in the Building, such rights
and/or options shall not run to the subtenant or assignee, it being agreed by
the parties hereto that any such rights and options are personal to the Tenant
originally named herein and may not be transferred.

            16.4 Documentation.

                (a) Prior to any assignment or sublease, Tenant shall (a)
provide to Landlord the proposed assignee's or sublessee's name, legal
composition, address, financial statements for the previous three (3) years (if
available), and copies of all documents relating to Tenant's proposed assignment
or sublease, and (b) shall specify all monies and other consideration to be
received by Tenant for such assignment or sublease.

                (b) In circumstances where Landlord's prior consent is required,
within thirty (30) days after the receipt of such documentation, and subject to
the provisions of Section 16.6 below, Landlord shall have the right to (a)
consent in writing to the proposed assignment or sublease subject to the terms
and conditions hereinafter set forth, or (b) notify Tenant in writing that
Landlord withholds such consent.

                (c) No permitted assignment or subletting by Tenant shall be
effective until there has been delivered to Landlord a fully executed
counterpart of the assignment or sublease which expressly provides that (a) the
assignee or subtenant may not further assign or sublet the assigned or sublet
space without Landlord's prior written consent (which, in the case of a further
assignment proposed by an assignee, shall not be unreasonably withheld, subject
to Landlord's rights under the provisions of this Paragraph 16), (b) the
assignee or subtenant will comply with all of the provisions of this Lease
(applicable, in the case of a sublease, to the portion of the Premises
subleased, and excluding the obligation to pay rent as described herein), and
Landlord may enforce the Lease provisions directly against such assignee, (c) in
the case of an assignment, the assignee assumes all of Tenant's obligations
under this Lease arising on or after the date of the assignment, and (d) in the
case of a sublease, the subtenant agrees to be and remain liable for the payment
of rent pertaining to the sublet space in the amount set forth


                                       17
<PAGE>   22

in the sublease, and for the performance of all of the terms and provisions of
this Lease applicable to such sublet space. In addition to the foregoing, no
sublease by Tenant shall be effective until there has been delivered to Landlord
a fully executed counterpart of Landlord's consent to sublease form. The failure
or refusal of a subtenant or assignee to execute any such instrument shall not
release or discharge the subtenant or assignee from its liability as set forth
above. Notwithstanding the foregoing, however, no subtenant or assignee shall be
permitted to occupy the Premises unless and until such subtenant or assignee
provides Landlord with certificates evidencing that such subtenant or assignee
is carrying all insurance coverage required of such subtenant or assignee under
this Lease.

            16.5 Excess Consideration. If Landlord consents to a proposed
assignment or subletting, Tenant shall pay to Landlord as additional rent,
within ten (10) days after receipt by Tenant, any consideration paid by the
subtenant or assignee, including, in the case of a sublease, the excess of the
rent and other consideration payable by the subtenant, over the amount of Base
Rent and Additional Rent payable hereunder applicable to the subleased space.

            16.6 Landlord's Right to Space. Notwithstanding any of the above
provisions of this Paragraph 16 to the contrary, if Tenant notifies Landlord
that it desires to enter into a sublease or assignment, Landlord, in lieu of
consenting to such transaction, may elect (a) in the case of an assignment or a
sublease of the entire Premises, to terminate this Lease or to sublease the
Premises from Tenant at the lesser of the rental rate payable hereunder or the
rate payable under such proposed transaction, or (y) in the case of a sublease
of less than the entire Premises, to terminate this Lease as it relates to the
space proposed to be subleased by Tenant or to sublease such portions of the
Premises at the lesser of the rental rate payable hereunder or the rate payable
under such proposed transaction. In the event Landlord elects to so terminate
this Lease or sublease such space, this Lease will terminate (or the space
proposed to be subleased will be removed from the Premises subject to this Lease
and the Base Rent and Tenant's Share under this Lease shall be proportionately
reduced) on the date the sublease or assignment was proposed by Tenant to be
effective, and Landlord may lease such space to any party, including the
prospective sublessee or assignee identified by Tenant. In any event, Tenant
shall bear the costs of any demising walls and code-related work associated with
such sublease or termination.

            16.7 Terms and Conditions. In connection with any proposed
assignment or sublease, Tenant shall pay Landlord's reasonable processing costs
and attorneys' fees, regardless of whether Landlord consents to such assignment
or sublease. Each assignment or sublease shall be in form satisfactory to
Landlord and shall be subject and subordinate to the provisions of this Lease.
Once approved by Landlord, such assignment or sublease shall not be modified
without Landlord's prior written consent. Each assignee or sublessee shall
acknowledge that the termination of this Lease shall, at Landlord's sole
election, constitute a termination of every such assignment or sublease.
Notwithstanding any assignment or sublease, Tenant shall remain primarily liable
for all obligations and liabilities of Tenant under this Lease.

            16.8 Landlord's Remedies. Any assignment or sublease without
Landlord's prior written consent where such consent is required shall at
Landlord's election be void, and shall at Landlord's election constitute a
default under this Lease. The consent by Landlord to any assignment or sublease
shall not constitute a waiver of the provisions of this Paragraph 16 with
respect to any subsequent assignment or sublease.


                                       18
<PAGE>   23

          16.9 No Merger. Without limiting any of the provisions of this
Paragraph 16, if Tenant has entered into any subleases of any portion of the
Premises, the voluntary or other surrender of this Lease by Tenant, or a mutual
cancellation by Landlord and Tenant, shall not work a merger, and shall, at the
option of Landlord, terminate all or any existing subleases or subtenancies or,
at the option of Landlord, operate as an assignment to Landlord of any or all
such subleases or subtenancies. If Landlord does elect that such surrender or
cancellation operate as an assignment of such subleases or subtenancies,
Landlord shall in no way be liable for any previous act or omission by Tenant
under the subleases or for the return of any deposit(s) under the subleases
that have not been actually delivered to Landlord, nor shall Landlord be bound
by any sublease modification(s) executed without Landlord's consent or for any
advance rental payment by the subtenant in excess of one month's rent.

          16.10 Assignment of Sublease Rents. Tenant hereby absolutely and
irrevocably assigns to Landlord any and all rights to receive rent and other
consideration from any sublease and agrees that Landlord, as assignee or as
attorney-in-fact for Tenant for purposes hereof, or a receiver for Tenant
appointment on Landlord's application may (but shall not be obligated to)
collect such rents and other consideration and apply the same toward Tenant's
obligations to Landlord under this Lease; provided, however, that Landlord
grants to Tenant at all times prior to occurrence of any breach or default by
Tenant a revocable license to collect such rents (which license shall
automatically and without notice be and be deemed to have been revoked and
terminated immediately upon any Event of Default [defined below]).

     17.  Default.

          17.1 Event of Default. The occurrence of any of the following events
(an "Event of Default") shall constitute a default and breach of this Lease by
Tenant:

               (a) Tenant fails to occupy and use the Premises for fifteen (15)
consecutive days, which failure shall be deemed an abandonment of the Premises
by Tenant; or

               (b) The failure by Tenant to make any payment of rent or any
other required payment, as and when due; or

               (c) Tenant's failure to perform any other term, covenant or
condition contained in this Lease and such failure shall have continued for
thirty (30) days after written notice of such failure is given to Tenant;
provided that where such failure cannot reasonably be cured within said thirty
(30) day period, Tenant shall not be in default if Tenant commences such cure
within said thirty (30) day period and thereafter diligently pursues all
reasonable efforts to complete said cure until completion thereof; or

               (d) Tenant fails to deliver any estoppel certificate, pursuant
to Paragraph 20 below, or subordination agreement, pursuant to Paragraph 21
below, or other document pursuant to Paragraph 19 below, within the applicable
period set forth therein;

               (e) Tenant makes or has made or furnishes or has furnished any
warranty, representation or statement to Landlord in connection with this
Lease, or any other



                                       19
<PAGE>   24
agreement made by Tenant for the benefit of Landlord, which is or was false or
misleading in any material respect when made or furnished, or

                (f) Tenant assigns this Lease or subleases any portion of the
Premises in violation of Paragraph 16 above; or

                (g) A default by Tenant occurs under any other lease between
Tenant and Landlord or any affiliate of Landlord, and Tenant fails to cure such
default within the applicable period set forth therein; or

                (h) the bankruptcy or insolvency of Tenant, transfer by Tenant
in fraud of creditors, an assignment by Tenant for the benefit of creditors, or
the commencement of any proceedings of any kind by or against Tenant under any
provision of the Federal Bankruptcy Act or under any other insolvency,
bankruptcy or reorganization act unless, in the event any such proceedings are
involuntary, Tenant is discharged from the same within thirty (30) days
thereafter.

            17.2 Remedies. Upon any Event of Default, Landlord shall have the
following remedies, in addition to all other remedies now or hereafter provided
by law or equity:

                (a) Termination. In any notice given pursuant to Paragraph 17.1
above, Landlord in its sole discretion may elect to declare a forfeiture of this
Lease as provided in Section 1161 of the California Code of Civil Procedure, and
provided that Landlord's notice states such an election, Tenant's right to
possession shall terminate and this Lease shall terminate, unless on or before
the date specified in such notice (conforming to the periods described in
Paragraph 17.1 above), all arrears of rent and all other sums payable by Tenant
under this Lease and all costs and expenses incurred by or on behalf of Landlord
hereunder, including attorneys' fees incurred in connection with such defaults,
shall have been paid by Tenant and all other breaches of this Lease by Tenant at
the time existing shall have been fully remedied to the satisfaction of
Landlord. Provided that Landlord serves notice in accordance with the provisions
of this Lease, Tenant hereby waives any notice required by Section 1161 of the
California Code of Civil Procedure. Upon such termination, Landlord may, at its
option and without any further notice or demand, in addition to any other rights
and remedies given hereunder or by law, exercise its remedies relating hereto in
accordance with the following provisions:

                    (i) In the event of any such termination of this Lease,
Landlord may then or at any time thereafter by judicial process, re-enter the
Premises and remove therefrom all persons and property and again repossess and
enjoy the Premises, without prejudice to any other remedies that Landlord may
have by reason of Tenant's default or of such termination.

                    (ii) In the event of any such termination of this Lease, and
in addition to any other rights and remedies Landlord may have, Landlord shall
have all of the rights And remedies of a landlord provided by Section 1951.2 of
the California Civil Code or any successor code section. Upon such termination,
in addition to any other rights and remedies to which Landlord may be entitled
under applicable law, Landlord shall be entitled to recover


                                       20
<PAGE>   25
from Tenant: (i) the worth at the time of award of the unpaid Rent and other
amounts which had been earned at the time of termination; (ii) the worth at the
time of award of the amount by which the unpaid Rent which would have been
earned after termination until the time of award exceeds the amount of such Rent
loss that the Tenant proves could have been reasonably avoided; (iii) the worth
at the time of award of the amount by which the unpaid Rent for the balance of
the Term after the time of award exceeds the amount of such Rent loss that the
Tenant proves could be reasonably avoided; and (iv) any other amount necessary
to compensate Landlord for all the detriment caused by Tenant's failure to
perform its obligations under this Lease or which, in the ordinary course of
things, would be likely to result therefrom. The "worth at the time of award" of
the amounts referred to in (i) and (ii) shall be computed with interest at the
lesser of eighteen percent (18%) per annum or the maximum rate allowed by law.
The "worth at the time of award" of the amount referred to in (iii) shall be
computed by reference to competent appraisal evidence or the formula prescribed
by and using the lowest discount rate permitted under applicable law.

                    (iii) For purposes of computing unpaid Rent which would have
accrued and become payable under this Lease pursuant to the provisions of
Paragraph 17(2)(a)(ii) above, unpaid Rent shall consist of the aggregate sum
of:

                         (1) the total Base Rent for the balance of the Term;
plus

                         (2) any other amounts which Tenant has agreed to pay or
which Tenant owes to Landlord under the terms of this Lease, except any amounts
owed for increases (estimated or actual) in Operating Expenses and Tax Expenses;
plus

                         (3) a computation of Tenant's Share of the Operating
Expenses and Tax Expenses increases for the balance of the Term, the assumed
Operating Expenses and Tax Expenses for the calendar year of the default and
each future calendar year in the Term to be equal to the Operating Expenses and
Tax Expenses for the final calendar year prior to such termination, increased at
a per annum rate equal to the mean average rate of inflation for the proceeding
three (3) calendar years as determined by reference to the Consumer Price Index,
All Items, San Francisco-Oakland-San Jose.

                    (iv) After terminating this Lease, Landlord may remove any
and all personal property located in the Premises and place such property in a
public or private warehouse or elsewhere at the sole cost and expense of Tenant.
In the event that Tenant shall not immediately pay the cost of storage of such
property after the same has been stored for a period of thirty (30) days or
more, Landlord may sell any or all thereof at a public or private sale in such
manner and at such times and places as Landlord in its sole discretion may deem
proper, without notice to or demand upon Tenant. Tenant waives all claims for
damages that may be caused by Landlord's removing or storing or selling the
property as herein provided, and Tenant shall indemnify and hold Landlord free
and harmless from and against any and all losses, costs and damages, including
without limitation all costs of court and attorneys' fees of Landlord occasioned
thereby.

                                       21
<PAGE>   26

                (b) Continuation After Default. If an Event of Default exists
under this Lease, Landlord shall also have the remedy described in California
Civil Code Section 1951.4 (Landlord may continue this Lease in effect after
Tenant has breached this Lease and recover rent as it becomes due; provided,
however that Tenant shall have the right to sublet or assign this Lease, subject
only to reasonable limitations). Acts of maintenance or preservation or efforts
to relet the Premises or the appointment of a receiver upon initiative of
Landlord to protect Landlord's interest under this Lease shall not constitute a
termination of Tenant's right to possession.

                (c) Bankruptcy/Insolvency. In the event of the occurrence of any
of the events specified in Paragraph 17.1(i) of this Lease, if Landlord shall
not choose to exercise, or by law shall not be able to exercise, its rights
hereunder to terminate this Lease, then, in addition to any other rights of
Landlord hereunder or by law, (1) Landlord my discontinue the services provided
pursuant to Paragraph 9 of this Lease, unless Landlord has received compensation
in advance for such services (it being agreed that it is reasonable for Landlord
to require the deposit of three (3) months' estimated cost of performing such
services) in the amount of Landlord's reasonable estimate of the compensation
required with respect to such services, and (2) neither Tenant, as
debtor-in-possession, nor any trustee or other person (collectively, the
"Assuming Tenant") shall be entitled to assume this Lease unless on or before
the date of such assumption, the Assuming Tenant (a) cures, or provides adequate
assurance that the Assuming Tenant will promptly cure, any existing default
under this Lease, (b) compensates, or provides adequate assurance that the
Assuming Tenant will promptly compensate, Landlord for any pecuniary loss
(including, without limitation, attorneys' fees and disbursements) resulting
from such default, and (c) provides adequate assurance of future performance
under this Lease; provided, however, that:

                    (i) The Assuming Tenant shall also deposit with Landlord, as
security for the timely payment of all Rent, an amount equal to six months'
Rent;

                    (ii) The obligations imposed upon the Assuming Tenant shall
continue with respect to Tenant or any assignee of the Lease after the
completion of the bankruptcy proceedings; and

                    (iii) for purposes of this Paragraph 17, Landlord and Tenant
acknowledge that, in the context of a bankruptcy proceeding of Tenant, at a
minimum "adequate assurance" shall mean:

                         (a) The Assuming Tenant has and will continue to have
sufficient unencumbered assets after the payment of all secured obligations and
administrative expenses to assure Landlord that the Assuming Tenant will have
sufficient funds to fulfill the obligations of Tenant under this Lease as they
become due, and to keep the Premises properly staffed with sufficient employees
to conduct a fully-operational, actively-promoted business on the Premises; and

                         (b) The Bankruptcy Court shall have entered an order
segregating sufficient cash payable to Landlord and the Assuming Tenant shall
have granted a valid and perfected first lien and security interest or mortgage
in property of Tenant or Trustee,


                                       22
<PAGE>   27

acceptable as to value and kind to Landlord, to secure to Landlord the
obligation of the Trustee or Tenant to cure monetary or non-monetary defaults
under this Lease within the time periods set forth above.

            The foregoing shall not limit Landlord's other rights and remedies
under the United States Bankruptcy Code including but not limited to the right
to file a claim against Tenant and obtain the maximum amount allowed in
connection with such bankruptcy proceeding.

            17.3 No Relief From Forfeiture After Default. Tenant waives all
rights of redemption or relief from forfeiture under California Code of Civil
Procedure Sections 1174 and 1179, and under any other present or future law, in
the event Tenant is evicted or Landlord otherwise lawfully takes possession of
the Premises by reason of any Event of Default.

            17.4 Landlord's Right to Perform Tenant's Obligations. If Tenant
shall at any time fail to perform any obligation required of Tenant hereunder,
and provided Tenant has been provided a thirty (30) day notice from Landlord
concerning such obligation, then Landlord may, at its option, perform such
obligation to the extent Landlord deems desirable, and may pay any and all
reasonable expenses incidental thereto and employ counsel. No such action by
Landlord shall be deemed a waiver by Landlord of any of Landlord's rights or
remedies, or a release of Tenant from performance of such obligation. All sums
so paid by Landlord, together with an administrative fee of five percent (5%) of
the amount so paid, shall be due and payable by Tenant to Landlord on the day
immediately following Landlord's payment thereof. Landlord shall have the same
rights and remedies for the nonpayment of any such sums as for default by Tenant
in the payment of rent in addition to any other remedy available to Landlord.

            17.5 Remedies Not Exclusive. No remedy or election hereunder shall
be deemed exclusive but shall, wherever possible, be cumulative with all other
remedies available.

            17.6 Termination, Surrender and Abandonment. No act or conduct of
Landlord, including, without limitation, efforts to relet the Premises, an
action in unlawful detainer or service of notice upon Tenant or surrender of
possession by Tenant pursuant to such notice or action, shall extinguish the
liability of Tenant to pay rent or other sums due hereunder or terminate this
Lease, unless Landlord notifies Tenant in writing of Landlord's election to
terminate this Lease. No act or conduct of Landlord, including the acceptance of
the keys to the Premises, other than a written acknowledgment of acceptance of
surrender signed by Landlord, shall be deemed to be or constitute an acceptance
of the surrender of the Premises by Tenant prior to the expiration of the Lease
term. The surrender of this Lease by Tenant, voluntarily or otherwise, shall, at
Landlord's option, operate as an assignment to Landlord of any and all existing
assignments and subleases, or Landlord may elect to terminate any or all of such
assignments and subleases by notifying the assignees and sublessees of its
election within fifteen (15) days after such surrender.

            17.7 Attorney's Fees. If as a result of any breach or default in the
performance of any of the provisions of this Lease, Landlord uses the services
of an attorney in order to secure compliance with such provisions or recover
damages therefor, or to terminate this Lease or evict Tenant, Tenant shall
reimburse Landlord upon demand for any and all reasonable attorneys' fees and
expenses so incurred by Landlord, provided that if Tenant shall be the


                                       23
<PAGE>   28

prevailing party in any legal action brought by Landlord against Tenant, Tenant
shall be entitled to recover reasonable attorneys' fees and expenses incurred by
Tenant.

            17.8 Landlord's Default. In the event of any failure by Landlord to
perform any of Landlord's obligations under this Lease, Tenant will give
Landlord and any Lender (defined in Paragraph 19 below) written notice
specifying such default with particularity, and Landlord shall thereupon have
sixty (60) days in which to cure any such default. Unless and until Landlord (or
such Lender) fails to so cure any default after such notice, Tenant shall not
have any remedy or cause of action by reason thereof. Notwithstanding anything
to the contrary set forth in this Lease, in no event shall Landlord be liable
for any consequential or remote damages, including, without limitation, loss or
interruption of Tenant's business.

        18. Effect of Conveyance. The term "Landlord" as used in this Lease,
means only the current owner(s) of the Building so that in the event of any sale
or other transfer of the Building, the transferor shall be deemed to be relieved
of all obligations of the Landlord hereunder from and after the date of such
sale (except such obligations arising before the date of such sale), and the
transferee shall be deemed to have assumed and agreed to perform any and all
obligations of Landlord hereunder arising from and after said date.

        19. Instruments Required by Lender. If any lender or ground lessor that
intends to acquire an interest in, or holds a mortgage, ground lease or deed of
trust encumbering any portion of the Property ("Lender") should require either
the execution by Tenant of an agreement requiring Tenant to send such Lender
written notice of any default by Landlord under this Lease, giving such Lender
the right to cure such default until such Lender has completed foreclosure, and
preventing Tenant from terminating this Lease unless such default remains
uncured after foreclosure has been completed, and/or any modification of the
agreements, covenants, conditions or provisions of this Lease, then Tenant
agrees that it shall, within ten (10) days after Landlord's request, execute and
deliver such agreement and modify this Lease as required by such Lender;
provided, however, that no such modification shall affect the length of the term
or increase the rent payable by Tenant hereunder. Tenant acknowledges and agrees
that its failure to timely execute any such agreement or modification required
by such lender or ground lessor may cause Landlord serious financial damage by
causing the failure of a financing transaction and giving Landlord all of its
rights and remedies under Paragraph 17, including its right to damages caused by
the loss of such financing.

        20. Estoppel Certificates. Tenant shall, from time to time, within ten
(10) days after receipt from Landlord of written request therefor, deliver a
duly executed and acknowledged and factually accurate estoppel certificate to
Landlord certifying: (i) that this Lease is unmodified and in full force and
effect, or if there has been any modification, that the same is in full force
and effect as modified, and stating all such modifications; (ii) whether or not
there is then existing any claim by Tenant of default hereunder by Landlord and,
if so, specifying the nature thereof; and (iii) the dates to which the rent and
other charges payable hereunder by Tenant have been paid. If Tenant fails to
timely deliver an estoppel certificate pursuant to the provisions of this
Paragraph 20, Tenant acknowledges that such failure may cause Landlord serious
financial damage by causing the failure of a financing or sale transaction and
giving Landlord all of its rights under Paragraph 17, including its right to
damages caused by the loss of such financing or sale.


                                       24
<PAGE>   29

        21. Subordination and Attornment. Tenant agrees that this Lease is
subject and subordinate to any mortgage, deed of trust, any other instrument of
security, or ground lease which is now or shall be placed on the Property. This
subordination is hereby made effective without any further act of Tenant. Tenant
shall, at any time hereafter, on demand, execute any instruments, releases, or
other documents that may be required by any Lender under any security instrument
for the purpose of subjecting and subordinating this Lease to the lien of such
instrument. Tenant shall attorn to any third party purchasing or otherwise
acquiring the Premises at any sale or other proceeding or pursuant to the
exercise of any rights, powers or remedies under any instruments of security or
ground leases now or hereafter encumbering all or any part of the Premises, as
if such third party had been named as Landlord under this Lease.

        22. Notices. All notices, demands or requests to be given to Tenant or
Landlord shall be in writing, delivered personally or by commercial courier or
by United States mail, postage prepaid, certified return receipt requested and
addressed (a) to Tenant at the Premises or (b) to Landlord at the address
specified in the Lease Summary or as it may otherwise from time to time
designate to Tenant in writing. Each such notice, demand or request shall be
deemed to have been received by Tenant or Landlord upon actual delivery.

        23. No Accord and Satisfaction. No payment by Tenant, or receipt by
Landlord, of an amount which is less than the full amount of Base Rent and all
other sums payable by Tenant hereunder at such time shall be deemed to be other
than on account of (a) the earliest of such other sums due and payable, and
thereafter (b) to the earliest Base Rent or other sum due and payable hereunder.
No endorsement or statement on any check or any letter accompanying any payment
of Base Rent or such other sums shall be deemed an accord and satisfaction, and
Landlord may accept any such check or payment without prejudice to Landlord's
right to receive payment of the balance of such rent and/or other sums, or
Landlord's right to pursue Landlord's remedies.

        24. Attorneys' Fees. If any action or proceeding at law or in equity, or
an arbitration proceeding shall be brought to recover any rent under this Lease,
or for or on account of any breach of or to enforce or interpret any of the
terms, covenants, or conditions of this Lease, or for the recovery of possession
of the Premises, the Prevailing Party (defined below) shall be entitled to
recover from the other party as a part of such action or in a separate action
brought for that purpose, its reasonable attorneys' fees and costs and expenses
incurred in connection with the prosecution or defense of such action.
"Prevailing Party" as used in this paragraph shall include, without limitation,
a party who brings an action against the other after the other is in breach or
default, if such action is dismissed upon the other's payment of the sums
allegedly due or upon the performance of the covenants allegedly breached, or if
the party commencing such action or proceeding obtains substantially the relief
sought by it in such action, whether or not such action proceeds to a final
judgment or determination.

        25. Surrender; Holding Over

            25.1 Surrender. Upon the expiration or termination of this Lease,
Tenant shall surrender the Premises and all Tenant Improvements and Alterations
to Landlord broom-clean and in their original condition, except for reasonable
wear and tear, damage from casualty or condemnation and any changes resulting
from approved Alterations; provided, however, that


                                       25
<PAGE>   30

prior to the expiration or termination of this Lease Tenant shall remove all
telephone and other cabling installed in the Building by or for Tenant and
remove from the Premises all Tenant's personal property, trade fixtures and
Alterations that Tenant has the right or is required by Landlord to remove under
the provisions of this Lease, and repair any damage caused by such removal. If
such removal is not completed before the expiration or termination of the Term,
Landlord shall have the right (but no obligation) to remove the same, and Tenant
shall pay Landlord on demand for all costs of removal and storage thereof
(including Landlord's administrative fee of fifteen percent (15%) of the cost of
performing such work) and for the rental value of the Premises for the period
from the end of the Term through the end of the time reasonably required for
such removal. Landlord shall also have the right to retain or dispose of all or
any portion of such property if Tenant does not pay all such costs and retrieve
the property within ten (10) days after notice from Landlord (in which event
title to all such property described in Landlord's notice shall be transferred
to and vest in Landlord). Tenant waives all claims against Landlord for any
damage or loss to Tenant resulting from Landlord's removal, storage, retention,
or disposition of any such property. Upon expiration or termination of this
Lease or of Tenant's possession, whichever is earliest, Tenant shall surrender
all keys to the Premises or any other part of the Building and shall deliver to
Landlord all keys for or make known to Landlord the combination of locks on all
safes, cabinets and vaults that may be located in the Premises. Tenant's
obligations under this Paragraph 25.1 shall survive the expiration or
termination of this Lease.

            25.2 Holdover Rent. This Lease shall terminate without further
notice at the expiration of the Term. Any holding over after the expiration of
the Term without proration for daily occupancy, shall be construed to be a
tenancy from month to month, at a monthly rental of two hundred percent (200%)
of the last applicable Base Rent and Additional Rent payable hereunder, and
shall otherwise be on the terms and conditions herein specified.

            25.3 Indemnity. To the fullest extent permitted under applicable
law, Tenant shall indemnify, defend, protect and hold Landlord harmless from and
against any and all loss, cost, damage or liability incurred by or asserted
against Landlord and arising directly or indirectly from Tenant's failure to
timely surrender the Premises, including but not limited to (i) any rent payable
by or any loss, cost, or damages, including lost profits, claimed by any
prospective tenant of the Premises or any portion thereof, and (ii) Landlord's
damages as a result of such prospective tenant rescinding or refusing to enter
into the prospective lease of the Premises or any portion thereof by reason of
such failure to timely surrender the Premises.

        26. Landlord Liability. The term "Landlord," as used in this Lease,
shall mean only the owner or owners of the Building at the time in question.
Notwithstanding any other term or provision of this Lease, the liability of
Landlord for its obligations under this Lease is limited solely to Landlord's
interest in the Building as the same may from time to time be encumbered, and no
personal liability shall at any time be asserted or enforceable against any
other assets of Landlord or against Landlord's partners or members or its or
their respective partners, shareholders, members, directors, officers or
managers on account of any of Landlord's obligations or actions under this
Lease.

        27. Entry, Inspection and Closure. Upon reasonable oral or written
notice to Tenant (and without notice in emergencies), Landlord and its
authorized representatives may enter the

                                       26
<PAGE>   31
Premises at all reasonable times to determine whether the Premises are in good
condition, to determine whether Tenant is complying with its obligations under
this Lease, to perform any maintenance or repair of the Premises or the Building
that Landlord has the right or obligation to perform, to install or repair
improvements for other tenants where access to the Premises is required for such
installation or repair, to serve, post or keep posted any notices required or
allowed under the provisions of this Lease, to show the Premises to prospective
brokers, agents, buyers, transferees, mortgagees or tenants, or to do any other
act or thing necessary for the safety or preservation of the Premises or the
Building. When reasonably necessary Landlord may temporarily close entrances,
doors, corridors, elevators or other facilities in the Building without
liability to Tenant by reason of such closure. Landlord shall conduct its
activities under this Paragraph in a manner that will minimize inconvenience to
Tenant without incurring additional expense to Landlord. In no event shall
Tenant be entitled to an abatement of rent on account of any entry by Landlord,
and Landlord shall not be liable in any manner for any inconvenience, loss of
business or other damage to Tenant or other persons arising out of Landlord's
entry on the Premises in accordance with this Paragraph. No action by Landlord
pursuant to this paragraph shall constitute an eviction of Tenant, constructive
or otherwise, entitle Tenant to an abatement of rent or to terminate this Lease
or otherwise release Tenant from any of Tenant's obligations under this Lease.

        28. Rules and Regulations. Tenant shall be bound by and shall comply
with the rules and regulations attached to and made a part of this Lease as
Exhibit C to the extent those rules and regulations are not in conflict with the
terms of this Lease, as well as any reasonable rules and regulations hereafter
adopted by Landlord for all tenants of the Building, upon notice to Tenant
thereof (collectively, the "Building Rules"). Landlord shall not be responsible
to Tenant or to any other person for any violation of, or failure to observe,
the Building Rules by any other tenant or other person.

        29. Consents and Approvals. Wherever the consent, approval, judgment or
determination of Landlord is required or permitted under this Lease, Landlord
may exercise its sole discretion in granting or withholding such consent or
approval or in making such judgment or determination without reference to any
extrinsic standard of reasonableness, unless the provision providing for such
consent, approval, judgment or determination specifies that Landlord's consent
or approval is not to be unreasonably withheld, or that the standard for such
consent, approval, judgment or determination is to be reasonable, or otherwise
specifies the standards under which Landlord may withhold its consent. Whenever
Tenant requests Landlord to take any action or give any consent or approval,
Tenant shall reimburse Landlord for all of Landlord's costs incurred in
reviewing the proposed action or consent (whether or not Landlord consents to
any such proposed action), including without limitation reasonable attorneys' or
consultants' fees and expenses, within ten (10) days after Landlord's delivery
to Tenant of a statement of such costs. If it is determined that Landlord failed
to give its consent or approval where it was required to do so under this Lease,
Tenant's sole remedy will be an order of specific performance or mandatory
injunction of the Landlord's agreement to give its consent or approval. The
review and/or approval by Landlord of any item shall not impose upon Landlord
any liability for accuracy or sufficiency of any such item or the quality or
suitability of such item for its intended use. Any such review or approval is
for the sole purpose of protecting Landlord's interest in the Real Property, and
neither Tenant nor any Tenant Party nor


                                       27
<PAGE>   32

any person or entity claiming by, through or under Tenant, nor any other third
party shall have any rights hereunder by virtue of such review and/or approval
by Landlord.

        30. Reserved Rights. Landlord retains and shall have the rights set
forth below, exercisable without notice and without liability to Tenant for
damage or injury to property, person or business and without effecting an
eviction, constructive or actual, or disturbance of Tenant's use or possession
of the Premises or giving rise to any claim for rent abatement:

            (a) To grant to anyone the exclusive right to conduct any business
                or render any service in or to the Building and its tenants,
                provided that such exclusive right shall not operate to require
                Tenant to use or patronize such business or service or to
                exclude Tenant from its use of the Premises expressly permitted
                herein.

            (b) To perform, or cause or permit to be performed, at any time and
                from time to time, including during Business Hours, construction
                in the common areas and facilities or other leased areas in the
                Real Property.

            (c) To reduce, increase, enclose or otherwise change at any time and
                from time to time the size, number, location, lay-out and nature
                of the common areas and facilities and other tenancies and
                premises in the Real Property and to create additional rentable
                areas through use or enclosure of common areas.

        31. Financial Statements. Upon submission of this Lease to Landlord and
at any time thereafter within ten (10) days after Landlord's request therefor,
Tenant shall furnish to Landlord copies of true and accurate financial
statements prepared in accordance with generally accepted accounting principles,
reflecting Tenant's then current financial situation (including without
limitation balance sheets, statements, of profit and loss, and changes in
financial condition), Tenant's most recent audited or certified annual financial
statements, and Tenant's federal income tax returns pertaining to Tenant's
business, and in addition shall cause to be furnished to Landlord similar
financial statements and tax returns for any guarantor(s) of this Lease. Tenant
agrees to deliver to any lender, prospective lender, purchaser or prospective
purchaser designated by Landlord such financial statements of Tenant as may be
reasonably requested by such lender or purchaser.

        32. Parking. No parking rights are conveyed to Tenant pursuant to this
Lease.

        33. General Provisions.

            33.1 Entire Agreement. This instrument, together with the Lease

inability excepted), then upon notice to the other party, the performance of
such act shall be excused for the period of the delay and the period for the

                                   WORK LETTER


        1. General.

            (a) Purpose. The Purpose of this Agreement is to set forth the
manner in which the Tenant Improvements (i.e., the improvements to be
constructed within the Premises) are to be constructed, who will design and
construct the Tenant Improvements and the allocation of the cost of the Tenant
Improvements.

            (b) Terms. All terms used herein and not herein defined shall have
the same meaning as the defined term in the Lease.


            (c) Condition of Premises. Except for the Tenant Improvements to be
constructed pursuant to this Agreement, Tenant accepts the Premises in their "as
is" condition and acknowledges that Tenant has had an opportunity to inspect the
Premises prior to signing the Lease.

        2. Commencement Date. The Commencement Date shall be determined in
accordance with the Lease Summary and Paragraph 2 of the Lease.

        3. Selection of Designer. The space Plans (defined below) shall be
prepared by a designer selected by Tenant and approved in advance by Landlord
(such approval not to be unreasonably withheld or delayed) ("Designer"). Tenant
shall at all times cooperate fully with Designer in Designer's efforts to timely
complete the Plans.

        4. Costs.

            (a) Landlord's Allowance. Pursuant to the terms set forth below and
as Landlord's sole contribution to the cost of the design and construction of
the Tenant Improvements, Landlord shall contribute an amount up to the amount
specified in the Lease Summary as "Landlord's Allowance".

            (b) Tenant's Cost. Any cost incurred in the design or construction
of the Tenant Improvements in excess of Landlord's Allowance shall be borne by
Tenant, in accordance with the terms and conditions set forth below. Prior to
the construction of the Tenant Improvements, Contractor (defined in Paragraph 6
below) shall submit an estimate of the total cost of completing the Tenant
Improvements. In the event that the aggregate of the cost estimated by
Contractor and the cost of designing and completion of the Tenant Improvements
(collectively, the "Improvements Cost") exceeds Landlord's Allowance, Tenant
shall deliver funds equal to such excess to Landlord prior to the commencement
of construction. In the event of any change order or any other event which
increases the Improvements Cost, Tenant shall, within ten (10) days following
delivery of notice to Tenant from Landlord, deliver to Landlord funds equal to
such increase. If Tenant fails to timely deliver such funds to Landlord,
Landlord



                                       32
<PAGE>   37

shall have no obligation to continue the work of the Tenant Improvements and may
cease such work until payment is received.

            (c) Construction Management Fee. Landlord shall receive a
construction management fee in the amount of five percent (5 %) of the
Improvements Cost, which shall be deducted from Landlord's Allowance.

            (d) Excess Landlord's Allowance. If Landlord's Allowance exceeds
the aggregate of the Improvements Costs and Landlord's Construction Management
Fee, any such excess may be applied by Tenant toward the completion of
alterations as the installation of equipment and/or wiring within the Premises,
provided that all such alterations shall be carried out in accordance with the
provisions of Article 5 of the Lease. Additionally, if and to the extent that
Tenant has not used all of such excess Landlord's Allowance on or before
December 31, 1998, any remaining Landlord's Allowance shall be revert back to
Landlord.

        5. Preparation of Plans.

            (a) Submittal of Plans. Landlord shall submit to Tenant proposed
plans for the Tenant Improvements ("Plans") prepared by Designer. Tenant shall
approve such Plans within three (3) business days of receipt or designate by
written notice to Landlord the specific changes required to be made to the Space
Plan, which changes, if approved by Landlord, shall be made by Landlord as soon
as reasonably possible. This procedure shall be repeated until the Plans are
finally approved by Tenant.

            (b) Limitation of Landlord's Liability. Tenant agrees and
understands that Landlord shall not be the guarantor of, nor responsible for,
the correctness or accuracy of any of the Plans or the compliance of the Plans
with applicable laws.


        6. Construction and Payment.

            (a) Construction of Tenant Improvements. Landlord shall retain a
contractor ("Contractor") to complete the Tenant Improvements in conformance
with the approved Plans and all applicable laws. Landlord shall make
arrangements to construct, as soon as reasonably possible, consistent with
industry custom and practice and all applicable laws, the Tenant Improvements.
Whenever possible and practical, Landlord will use the items and materials
designated in the approved Plans for the construction of the Tenant
Improvements. However, whenever Landlord determines in its judgment that it is
not practical or efficient to use such materials, Landlord shall have the right,
upon receipt of Tenant's consent, which consent shall not be unreasonably
withheld or delayed, to substitute comparable items and materials.

            (b) Tenant's Changes. In the event that Tenant requests any changes
from the approved Plans which changes shall be requested in a written notice to
Landlord, Landlord shall not unreasonably withhold its consent to any such
changes, provided the changes do not adversely affect the Building's structure,
systems, equipment, security system or appearance. The costs charged by Landlord
to Tenant caused by Tenant's requesting such changes shall be the amount of
money Landlord is required to pay to revise any plans, including, without


                                       33
<PAGE>   38


limitation, the approved plans, and to cause the Tenant Improvements, as
reflected by the revised approved Plans to be constructed above the costs that
Landlord would have had to pay to cause the Tenant Improvements to be
constructed if no changes had been made ("Differential"), plus an amount equal
to ten percent (10%) of the Differential to compensate Landlord for its time and
efforts in connection with such changes.

        7. Substantially Complete. As used herein, the terms "Substantially
Complete" or "Substantial Completion" shall mean that the Tenant Improvements
have been completed, notwithstanding the fact that minor details of
construction, mechanical adjustments or decorations which do not materially
interfere with Tenant's use of the Premises remain to be performed (items
normally referred to as "punchlist" items). The Premises shall be deemed
Substantially Complete even though Tenant's furniture, telephones, telexes,
telecopiers, photocopy machines, computers and other business machines or
equipment have not been installed, the purchase and installation of which shall
be Tenant's sole responsibility and which shall be carried out pursuant to the
terms of Paragraph 8 below. Landlord shall cause the punchlist items to be
corrected as soon as reasonably possible and practical, but Landlord's failure
to complete such items as of the date of Substantial Completion of the Premises
shall in no event delay the Commencement Date.

        8. Tenant's Work. Any items of work not shown in the approved Plans,
including, for example, the installation of telephone service, security system
or furnishings (including wiring and cabling connections or installations), for
which Tenant contracts separately, and (subject to the provisions of Section
4(d) above) at Tenant's sole cost and expense (hereinafter "Tenant's Work"),
shall be subject to Landlord's reasonable policies and schedules and shall be
conducted in such a way as not to hinder, cause any disharmony with or delay any
work of improvement in the Building. Tenant's suppliers, contractors, workmen
and mechanics shall be subject to approval by Landlord (not to be unreasonably
withheld or delayed) prior to the commencement of their work and shall be
subject to Landlord's administrative control while performing their work. Tenant
shall cause its suppliers and contractors to engage only labor that is
harmonious and compatible with other labor working in the Building. In the event
of any labor disturbance caused by persons employed by Tenant or Tenant's
contractor, Tenant shall immediately, and at Tenant's sole cost and expense,
take all actions necessary to eliminate such disturbance. If at any time any
supplier, contractor, workman or mechanic performing Tenant's Work hinders or
delays any other work of improvement in the Building or performs any work which
may or does impair the quality, integrity or performance of any portion of the
Building, Tenant shall, at Tenant's sole cost and expense, cause such supplier,
contractor, workman or mechanic to leave the Building and remove all his tools,
equipment and materials immediately upon written notice delivered to Tenant and
Tenant shall reimburse Landlord for any repairs or corrections of the Tenant
Improvements or Tenant's Work or of any portion of the Building caused by or
resulting from the work of any supplier, contractor, workman or mechanic with
whom Tenant contracts. Landlord shall give access to Tenant's suppliers,
contractors, workmen and mechanics so as to achieve timely completion and
occupancy of the Premises, Tenant shall be responsible for hoisting charges for
work under this paragraph.

        9. Default. Any default by Tenant under the terms of this Work Letter
shall constitute a default under the Lease to which this Work Letter is
attached, and shall entitle Landlord to exercise all remedies set forth in the
Lease. Tenant shall have any and all rights to remedy such default pursuant to
the provisions of the Lease.

        10. Tenant Improvements. The Tenant Improvements shall be constructed in
accordance with the approved Plans mid applicable laws, in a good and
workmanlike manner, free of defects and using new materials and equipment of
good quality. Landlord hereby assigns to Tenant all warranties with respect to
the Tenant Improvements, including warranties which would reduce Tenant's
maintenance obligations under the Lease, and shall cooperate, at no cost or
expense to Landlord, with Tenant in the enforcement of any such warranties.

            IN WITNESS WHEREOF, the parties have executed the Agreement as of
the date first written above.

                                   EXHIBIT C


                                 BUILDING RULES



        A. General Rules and Regulations. The following rules and regulations
govern the use of the Building and the Property common areas. Tenant will be
bound by such rules and regulations and agrees to cause Tenant, its employees,
subtenants, assignees, contractors, suppliers, customers and invitees to observe
the same.

            1. Except as specifically provided in the Lease to which these
Building Rules are attached, no sign, placard, picture, advertisement, name or
notice may be installed or displayed on any part of the outside or inside of the
Building without the prior written consent of Landlord, which may be withheld in
Landlord's sole discretion. Landlord will have the right to remove, at Tenant's
expense and without notice, any sign installed or displayed in violation of this
rule. All approved signs or lettering on doors and walls are to be printed,
painted, affixed or inscribed at the expense of Tenant and under the direction
of Landlord by a person or company reasonably designated or approved by
Landlord.

            2. If Landlord objects in writing to any curtains, blinds, shades,
screens or hanging plants or other similar objects attached to or used in
connection with any window or door of the Premises, or placed on any windowsill,
which is visible from the exterior of the Premises, Tenant will immediately
discontinue such use. Tenant agrees not to place anything against or near glass
partitions or doors or windows which may appear unsightly from outside the
Premises including from within any interior common areas.

            3. Tenant will not obstruct any sidewalks, halls, passages, exits,
entrances, elevators, escalators, or stairways of the Building or Property. The
halls, passages, exits, entrances, elevators and stairways are not open to the
general public, but are open, subject to reasonable regulations, to Tenant's
business invitees. Landlord will in all cases retain the right to control and
prevent access thereto of all persons whose presence in the reasonable judgment
of Landlord would be prejudicial to the safety, character, reputation and
interest of the Property and its tenants, provided that nothing herein contained
will be construed to prevent such access to persons with whom any tenant
normally deals in the ordinary course of its business, unless such persons are
engaged in illegal or unlawful activities. No tenant and no employee or invitee
of any tenant will go upon the roof of the Building.

            4. Tenant will not obtain for use on the Premises ice, drinking
water, food, food vendors, towel or other similar services (excluding bottled
water and soft drink vending machines) or accept barbering or bootblacking
service upon the Premises, except at such reasonable hours and under such
reasonable regulations as may be fixed by Landlord. Landlord expressly reserves
the right to absolutely prohibit solicitations, canvassing, distribution of
handbills or any other written material, peddling, sales and displays of
products, goods and wares in all portions of the Property except as may be
expressly permitted under the Lease. Landlord reserves the right to restrict and
regulate the use of the common areas of the Property and Building by invitees of
tenants providing services to tenants on a periodic or daily basis


                                       36
<PAGE>   41
including food and beverage vendors. Such restrictions may include limitations
on time, place, manner and duration of access to a tenant's premises for such
purposes. Without limiting the foregoing, Landlord may require that such parties
use service elevators, halls, passageways and stairways for such purposes to
preserve access within the Building for tenants and the general public.

            5. Landlord reserves the right to require tenants to periodically
provide Landlord with a written list of any and all business invitees which
periodically provide goods and services to such tenants at the premises.
Landlord reserves the right to preclude all vendors from entering or conducting
business within the Building and the Property if such vendors are not listed on
a tenant's list of requested vendors.

            6. Landlord reserves the right to exclude from the Building between
the hours of 6 p.m. and 8 a.m. the following business day, or such other hours
as may be established from time to time by Landlord, and on weekends and legal
holidays, any person unless that person is known to the person or employee in
charge of the Building or has a pass or is properly identified. Tenant will be
responsible for all persons for whom it requests passes and will be liable to
Landlord for all acts of such persons. Landlord will not be liable for damages
for any error with regard to the admission to or exclusion from the Building of
any person. Landlord reserves the right to prevent access to the Building in
case of invasion, mob, riot, public excitement or other commotion by closing the
doors or by other appropriate action.

            7. The directory of the Building will be provided exclusively for
the display of the name and location of tenants only and Landlord reserves the
right to exclude any other names therefrom.

            8. All cleaning and janitorial services for the Premises will be
provided exclusively through Landlord, and except with the written consent of
Landlord, no person or persons other than those approved by Landlord will be
employed by tenants or permitted to enter the Building for the purpose of
cleaning the same. Tenant will not cause any unnecessary labor by carelessness
or indifference to the good order and cleanliness of the Premises.

            9. Landlord will furnish Tenant, free of charge, with two keys to
each door lock in the Premises. Landlord may make a reasonable charge for any
additional keys. Tenant shall not make or have made additional keys, and Tenant
shall not alter any lock or install any new additional lock or bolt on any door
of the premises. Tenant, upon the termination of its tenancy, will deliver to
Landlord the keys to all doors which have been furnished to Tenant, and in the
event of loss of any keys so furnished, will pay Landlord therefor.

            10. If Tenant requires telegraphic, telephonic, burglar alarm,
satellite dishes, antennae or similar services, it will first obtain Landlord's
approval, which may be withheld in Landlord's sole discretion, and comply with,
Landlord's reasonable rules and requirements applicable to such services, which
may include separate licensing by, and fees paid to, Landlord.

            11. A freight elevator will be available for use by all tenants in
the Building, subject to such reasonable scheduling as Landlord, in its
discretion, deems appropriate. No equipment, materials, furniture, packages,
supplies, merchandise or other property will be



                                       37
<PAGE>   42

received in the Building or carried in the elevators except between such hours
and in such elevators as may be designated by Landlord. Tenant's initial move in
and subsequent deliveries of bulky items, such as furniture, safes and similar
items will, unless otherwise agreed in writing by Landlord, be made during the
hours of 6:00 p.m. to 6:00 a.m. or on Saturday or Sunday. Deliveries during
normal office hours shall be limited to normal office supplies and other small
items. No deliveries will be made which impede or interfere with other tenants
or the operation of the Building.

             12. Tenant will not place a load upon any floor of the Premises
which exceeds the load per square foot which such floor was designed to carry
and which is allowed by law. Landlord will have the right to reasonably
prescribe the weight, size and position of all safes, heavy equipment, files,
materials, furniture or other property brought into the Building. Heavy objects
will, if considered necessary by Landlord, stand on such platforms as determined
by Landlord to be necessary to properly distribute the weight, which platforms
will be provided at Tenant's expense. Business machines and mechanical equipment
belonging to Tenant, which cause noise or vibration that may be transmitted to
the structure of the Building or to any space therein to such a degree as to be
objectionable to any tenants in the Building or Landlord, are to be placed and
maintained by Tenant, at Tenant's expense, on vibration eliminators or other
devices sufficient to eliminate noise or vibration. Tenant will be responsible
for all structural engineering required to determine structural load, as well as
the expense thereof. The persons employed to move such equipment in or out of
the Building must be reasonably acceptable to Landlord. Landlord will not be
responsible for loss of, or damage to, any such equipment or other property from
any cause, and all damage done to the Building by maintaining or moving such
equipment or other property will be repaired at the expense of Tenant.

             13. Tenant will not use or keep in the Premises any kerosene,
gasoline or inflammable fluid or material other than those limited quantities
necessary for the operation or maintenance of office equipment. Tenant will not
use or permit to be used on the Premises any foul or noxious gas or substance,
or permit or allow the Premises to be occupied or used in a manner offensive or
objectionable to Landlord or other occupants of the Building by reason of noise,
odors or vibrations, nor will Tenant bring into or keep in or about the Premises
any birds or animals (other than animals assisting disabled invitees of Tenant).

             14. Tenant will not use any method of heating or air conditioning
other than that supplied by Landlord without Landlord's prior written consent.

             15. Tenant will not waste electricity, water or air conditioning
and agrees to cooperate fully with Landlord to assure the most effective
operation of the Building's heating and air conditioning and to comply with any
governmental energy-saving rules, laws or regulations of which Tenant has actual
notice, and will refrain from attempting to adjust controls. Tenant will keep
corridor doors closed, and shall keep all window coverings pulled down during
periods of solar exposure.

             16. Landlord reserves the right, exercisable without notice and
without liability to Tenant, to change the name and street address of the
Building. Without the written consent of Landlord, Tenant will not use the name
of the Building or the Property in connection with or in promoting or
advertising the business of Tenant except as Tenant's address.



                                       38
<PAGE>   43

            17. Tenant will close and lock the doors of its Premises and
entirely shut off all water faucets or other water apparatus, and lighting or
gas, before Tenant and its employees leave the Premises. Tenant will be
responsible for any damage or injuries sustained by other tenants, or occupants
of the Building or by Landlord for noncompliance with this rule.

            18. The toilet rooms, toilets, urinals, wash bowls and other
apparatus will not be used for any purpose other than that for which they were
constructed and no foreign substance of any kind whatsoever shall be thrown
therein. The expense of any breakage, stoppage or damage resulting from any
violation of this rule will be borne by the tenant who, or whose employees or
invitees, break this rule. Cleaning of equipment of any type is prohibited.
Shaving is prohibited.

            19. Tenant will not sell, or permit the sale at retail of
newspapers, magazines, periodicals, theater tickets or any other goods or
merchandise to the general public in or on the Premises. Tenant will not use the
Premises for any business or activity other than that specifically provided for
in this Lease. Tenant will not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Landlord's prior written consent, which consent Landlord may withhold
in its sole and absolute discretion.

            20. Tenant will not install any radio or television antenna,
loudspeaker, satellite dishes or other device on the roof(s) or exterior walls
of the Building or the Property. Tenant will not interfere with radio or
television broadcasting or reception from or in the Building or elsewhere.

            21. Except for the ordinary hanging of pictures and wall
decorations, Tenant will not mark, drive nails, screw or drill into the
partitions, woodwork or plaster or in any way deface the Premises or any part
thereof, except in accordance with the provisions of the Lease pertaining to
alterations. Landlord reserves the right to direct electricians as to where and
how telephone and telegraph wires are to be introduced to the Premises. Tenants
will not cut or bore holes for wires. Tenant will not affix any floor covering
to the floor of the Premises in any manner except as approved by Landlord.
Tenant shall repair any damage resulting from noncompliance with this rule.

            22. Tenant will not install, maintain or operate upon the Premises
any vending machines without the written consent of Landlord, not to be
unreasonably withheld or delayed.

            23. Landlord reserves the right to exclude or expel from the
Property any person who, in Landlord's judgment, is intoxicated or under
influence of liquor or drugs or who is in violation of any of the Building
Rules.

            24. Tenant will store all its trash and garbage within its Premises
or in other facilities provided by Landlord. Tenant will not place in any trash
box or receptacle any material which cannot be disposed of in the ordinary and
customary manner of trash and garbage disposal. All garbage and refuse disposal
is to be made in accordance with directions issued from time to time by
Landlord.



                                       39
<PAGE>   44

            25. The Premises will not be used for lodging or for the storage of
merchandise held for sale by the general public, or for lodging or for
manufacturing of any kind, nor shall the Premises be used for any illegal
purpose. No cooking will be done or permitted on the Premises without Landlord's
consent, except the use of Tenant of Underwriters' Laboratory approved equipment
for brewing coffee, tea, hot chocolate and similar beverages shall be permitted,
and the use of a microwave oven for employees use will be permitted, provided
that such equipment and use is in accordance with all applicable federal, state,
county and city laws, codes, ordinances, rules and regulations.

            26. Neither Tenant nor any of its employees, agents, customers and
invitees may use in any space or in the public halls of the Building or the
Property any hand truck except those quipped with rubber tires and side guards
or such other material-handling equipment as Landlord may approve. Tenant will
not bring any other vehicles of any kind into the Building.

            27. Tenant agrees to comply with all safety, fire protection and
evacuation procedures and regulations established by Landlord or any
governmental agency.

            28. Tenant assumes any and all responsibility for protecting its
Premises from theft, robbery and pilferage, which includes keeping doors locked
and other means of entry into the Premises closed.

            29. To the extent Landlord reasonably deems it necessary to exercise
exclusive control over any portions of the common areas for the mutual benefit
of the tenants in the Building or the Property, Landlord may do so subject to
reasonable, non-discriminatory additional rules and regulations.

            30. Landlord may prohibit smoking in the Building and may require
Tenant and any of its employees, agents, clients, customers, invitees and guests
who desire to smoke, to smoke within designated smoking areas within the
Property, which may be located outside of the Building.

            31. Tenant's requirements will be attended to only upon appropriate
application to Landlord's asset management office for the Building by an
authorized individual of Tenant. Employees of Landlord will not perform any work
or do anything outside of their regular duties unless under special instructions
from Landlord, and no employee of Landlord will admit any person (Tenant or
otherwise) to any office without specific instructions from Landlord.

            32. These Building Rules are in addition to, and will not be
construed to in any way modify or amend, in whole or in part, the terms,
covenants and conditions of the Lease. Landlord may waive any one or more of
these Building Rules for the benefit of Tenant or any other tenant, but no such
waiver by Landlord will be construed as a waiver of such Building Rules in favor
of Tenant or any other tenant, nor prevent Landlord from thereafter enforcing
any such Building Rules against any or all of the tenants of the Property.

            33. Landlord reserves the right to make such other and reasonable
non-discriminatory Building Rules as, in its judgment, may from time to time be
needed for safety and security, for care and cleanliness of the Property and for
the preservation of good order


                                       40
<PAGE>   45

therein. Tenant agrees to abide by all such Building Rules herein above stated
and any additional reasonable and non-discriminatory rules and regulations which
are adopted. Tenant is responsible for the observance of all the foregoing rules
by Tenant's employees, agents, clients, customers, invitees and guests.

        B. Parking Rules and Regulations. The following rules and regulations
govern the use of the parking facilities which serve the Building. Tenant will
be bound by such rules and regulations and agrees to cause its employees,
subtenants, assignees, contractors, suppliers, customers and invitees to observe
the same.

            1. Tenant will not permit or allow any vehicles that belong to or
are controlled by Tenant or Tenant's employees, subtenants, customers or
invitees to be loaded, unloaded or parked in areas other than those designated
by Landlord for such activities. No vehicles are to be left in the parking
areas overnight and no vehicles are to parked in the parking areas other than
normally sized passenger automobiles, motorcycles and pick-up trucks. No
extended term storage of vehicles is permitted.

            2. Vehicles must be parked entirely within painted stall lines of a
single parking stall.

            3. All directional signs and arrows must be observed.

            4. The speed limit within all parking areas shall be five (5) miles
per hour.

            5. Parking is prohibited: (a) in areas not striped for parking: (b)
in aisles or on ramps, (c) where "no parking" signs are posted; (d) in cross
hatched areas; and (e) in such other areas as may be designated from time to

            6. Landlord reserves the right, without cost or ability to Landlord,
to tow any vehicle if such vehicle's audio theft alarm system remains engaged
for an unreasonable period of time.

            7. Washing, waxing, cleaning or servicing of any vehicle in any area
not specifically reserved for such purpose is prohibited.

            8. Landlord may refuse to permit any person to park in the parking
facilities who violates these rules with unreasonable frequency, and any
violation of these rules shall subject the violator's car to removal, at such
car owner's expense. Tenant agrees to use its best efforts to acquaint its
employees, assignees, contractors, suppliers, customers and invitees with these
parking provisions, rules and regulations.

            9. Parking stickers, access cards, or any other form of
identification supplied by Landlord as a condition of use of the parking
facilities shall remain the property of Landlord. Parking identification
devices, if utilized by Landlord, must be displayed as requested and may not be
mutilated in any manner. The serial number of the parking identification device
may not be obliterated. Parking identification devices, if any, are not
transferable and any device in the possession of an unauthorized holder will be
void. Landlord reserves the right to refuse


                                       41
<PAGE>   46


the sale of monthly stickers or other parking identification devices to Tenant
or any of its agents, employees or representatives who willfully refuse to
comply with these rules and regulations and all unposted city, state or federal
ordinances, laws or agreements.

            10. Loss or theft of parking identification devices or access cards
must be reported to the management office for the Property immediately, and a
lost or stolen report must be filed by the Tenant or user of such parking
identification device or access card at the time. Landlord has the right to
exclude any vehicle from the parking facilities that does not have a parking
identification device or valid access card. Any parking identification device or
access card which is reported lost or stolen and which is subsequently found in
the possession of an unauthorized person will be confiscated and the illegal
holder will be subject to prosecution.

            11. All damage or loss claimed to be the responsibility of Landlord
must be reported, itemized in writing and delivered to the management office
located within the Building within ten (10) business days after any claimed
damage or loss occurs. Any claim not so made is waived. Landlord is not
responsible for damage by water or fire, or for the acts or omissions of others,
or for articles left in vehicles.

            12. The parking operators, managers or attendants, if any, are not
authorized to make or allow any exceptions to these rules and regulations,
without the express written consent of Landlord. Any exceptions to these rules
and regulations made by any parking operators, managers or attendants without
the express written consent of Landlord will not be deemed to have been approved
by Landlord.

            13. Landlord reserves the right, without cost or liability to
Landlord, to tow any vehicles which are used or parked in violation of these
rules and regulations.

            14. Landlord reserves the right from time to time to modify and/or
adopt such other reasonable and non-discriminatory rules and regulations for the
parking facilities as it deems reasonably necessary for the operation of the
parking facilities.

of this Rider shall control. Capitalized terms used herein shall have the
meaning given them in the Lease.

        1. Term (Article 1).

           (a) Option to Extend. Landlord hereby grants Tenant an option to
extend the Term (the "Option to Extend") for one (1) additional period of four
(4) years (the "Option Term"), commencing immediately after the expiration of
the initial Term, upon the same terms and conditions contained herein, except
that (i) the Base Rent for the Premises shall be increased to the Fair Market
Base Rent for the Premises (but in no event less than the Base Rent rate payable
immediately prior to the expiration of the initial Term, determined in the
manner set forth below, (ii) Tenant shall accept the Premises as of the
commencement of the Option Term in an "as is" condition without any obligation
of Landlord to repaint, remodel, repair, improve or alter the Premises, and
(iii) there shall be no further options to extend the Term.

               (1) Tenant's exercise of the Option to Extend must be given to
Landlord in writing no less than six (6) months and no earlier than nine (9)
months prior to the expiration of the Term. If Tenant properly exercises the
Option to Extend, references in this Lease to the Term shall be deemed to mean
the Option Term unless the context clearly provides otherwise. Notwithstanding
anything to the contrary contained herein, the Option to Extend shall
automatically terminate without notice and shall be of no further force and
effect, whether or not Tenant has timely exercised an option granted herein, if
(i) an event of default, beyond applicable cure periods, on the part of Tenant
exists under this Lease at the time of exercise of the Option to Extend or at
the time of commencement of the Option Term or (ii) Landlord has given Tenant
two or more notices respecting an Event of Default on the part of Tenant during
the Term.

               (2) If Tenant properly exercises the Option to Extend, the Base
Rent during the Option Term shall be determined in the following manner. The
Base Rent shall be increased to an amount equal to the Fair Market Base Rent for
the Premises as of the commencement of the Option Term for a term equal to the
Option Term, as specified by Landlord by notice to Tenant not less than thirty
(30) days prior to commencement of the Option Term, subject to Tenant's right of
arbitration as set forth below. If Tenant believes that the Fair Market Base
Rent specified by Landlord exceeds the actual Fair Market Base Rent for the
Premises as of commencement of the Option Term, then Tenant shall so notify
Landlord within ten (10) days following receipt of Landlord's notice. If Tenant
fails to so notify Landlord within said ten (10) days, Landlord's determination
of the Fair Market Base Rent for the Premises shall be final and binding upon
the parties. If the parties are unable to agree upon the Fair Market Base Rent
for the Premises within ten (10) days after Landlord's receipt of notice of
Tenant's



                                       43
<PAGE>   48

objection, the Base Rent payable as of commencement of the Option Term shall be
determined as follows:

                    A. Within fifteen (15) days after receipt of Landlord's
notice specifying Fair Market Base Rent, Tenant, at its sole expense, shall
obtain and deliver in writing to Landlord a determination of the Fair Market
Base Rent for the Premises for a term equal to the Option Term from a broker
("Tenant's Broker") licensed in the State of California and engaged in the
office brokerage business in Palo Alto, California vicinity for at least the
immediately preceding five (5) years. If Landlord accepts such determination,
the Base Rent for the Option Term shall be increased to an amount equal to the
amount determined by Tenant's Broker (but in no event shall such amount be less
than the Base Rent rate payable by Tenant immediately preceding the expiration
of the initial Term).

                   B. If Landlord does not accept such determination, within
15 days after receipt of the determination of Tenant's Broker, Landlord shall
designate a broker ("Landlord's Broker") licensed in the State of California and
engaged in the office brokerage business in Palo Alto, California vicinity for
at least the immediately preceding five (5) years. Landlord's Broker and
Tenant's Broker shall name a third broker (the "Third Broker"), similarly
qualified, within five (5) days after the appointment of Landlord's Broker. Each
of said three brokers shall determine the Fair Market Base Rent for the Premises
as of the commencement of the Option Term for a term equal to the Option Term
within 15 days after the appointment of the Third Broker. The Base Rent payable
by Tenant effective as of the commencement of the Option Term shall be increased
to an amount equal to the arithmetic average of such three determinations;
provided, further, that if any such broker's determination deviates more than
10% from the median of such determinations, the Base Rent payable shall be an
amount equal to the average of the two closest determinations; provided,
however, that in no event shall the Base Rent payable during the Option Term be
less than the Base Rent rate payable immediately preceding the expiration of the
initial Term.

               (3) Landlord shall pay the costs and fees of Landlord's Broker in
connection with any determination hereunder, and Tenant shall pay the costs and
fees of Tenant's Broker in connection with such determination. The costs and
fees of any Third Broker shall be paid one-half by Landlord and one-half by
Tenant. Tenant expressly acknowledges that any costs and fees arising in favor
of any broker hired by Tenant to represent Tenant in the negotiation of the
extension of the term of this Lease shall be borne solely by Tenant.

               (4) If the amount of the Fair Market Base Rent is not known as of
the commencement of the Option Term, then Tenant shall continue to pay the Base
Rent in effect at the expiration of the initial Term until the amount of the
Fair Market Base Rent is determined. When such determination is made, Tenant
shall pay to Landlord any deficiency to Landlord within thirty (30) days
following Landlord's delivery of an invoice therefore to Tenant.

           (b) Notwithstanding the provisions of Article 2 to the contrary, if
the Premises have not been delivered by May 30, 1998, solely due to delays
caused by Landlord, and not due, in whole or in part, to delays caused by or
attributable to Tenant or to force majeure, Tenant shall have the right, to be
exercised by written notice delivered to Landlord on or before June 10, 1998, to
terminate this Lease, effective as of June 10, 1998. If Tenant exercises such
right,



                                       44
<PAGE>   49
and if Landlord is unable to deliver Premises to Tenant on or before June 10,
1998, the Lease shall terminate as of June 10, 1998; provided, however, that if
Tenant exercises such right, and Landlord delivers the Premises to Tenant on or
before June 10, 1998, Tenant's exercise of the right provided herein shall be
null and void and of no further force or effect, and the Lease shall commence,
the same as if Tenant had not exercised such right.
