                              SUBLEASE AGREEMENT
                              ------------------

     1.   Parties. This Sublease Agreement (hereinafter referred to as the
          -------
"Sublease"), entered into this 24th day of August, 1999 is made by and between
STERLING SOFTWARE (WESTERN), INC., a Delaware corporation (hereinafter called
"Sublessor") on the one hand, and @ROAD, INC., a California corporation
(hereinafter referred to as "Sublessee") on the other hand.

     2.   Subleased Premises. Sublessor hereby subleases to Sublessee and
          ------------------
Sublessee hereby subleases from Sublessor for the Term (hereinafter defined), at
the rental, and upon all of the terms and conditions set forth in this Sublease,
that certain office space containing approximately 24,000 rentable square feet
comprising a portion of the building known as Building 2B of Spinnaker One
Office Park (hereinafter the "Building"), having a street address of 47370
Fremont Boulevard, Fremont, State of California, 94538, said space being more
particularly identified and described on Exhibit "A" attached hereto and
                                         -----------
incorporated herein by reference (hereinafter called the "Subleased Premises").

     3.   Term.
          ----

          3.1  Term. The term of this Sublease shall commence on the date (the
               ----
"Commencement Date") which is the later of: (i) September 15, 1999, or (ii) upon
receipt of a written Consent to Sublease from Prime Lessor as detailed in
Section 3.2 below. The term of this Sublease shall end at midnight on December
30, 2000 (the "Term"), unless sooner terminated pursuant to any provision
hereof.

          3.2  Improvements to Subleased Premises Prior to Commencement Date.
               -------------------------------------------------------------
Sublessee shall be permitted access to the Subleased Premises only after the
Prime Lessor (hereinafter defined) has executed and delivered to Sublessor and
Sublessee the Prime Lessor's Consent to Sublease form attached hereto as Exhibit
                                                                         -------
"C". In addition to the foregoing, Sublessor shall not be subject to any
---
liability to Sublessee in the event Sublessor is unable to obtain the Prime
Lessor's consent to this Sublease. If Sublessee occupies all or any portion of
the Subleased Premises for purposes of making improvements to the Subleased
Premises or otherwise prior to the Commencement Date or prior to Prime Lessor
executing and delivering to Sublessor and Sublessee the Prime Lessor's Consent
to Sublease form attached hereto as Exhibit "C", such occupancy by Sublessee
                                    -----------
shall be subject to all provisions of this Sublease, and such occupancy shall
not advance the termination date, and Sublessee shall have no obligation to pay
Base Rental for such period prior to the Commencement Date.

     4.   Rental.
          ------

          4.1  Base Rent. From and after the Commencement Date Sublessee shall
               ---------
pay to Sublessor annual rent for the Subleased Premises during the Term in the
amount of TWO HUNDRED FORTY FOUR THOUSAND EIGHT HUNDRED AND NO/100 ($244,800.00)
          ----------------------------------------------------------------------
DOLLARS, said annual rent to be paid in equal monthly installments in the amount
-------
of TWENTY THOUSAND FOUR HUNDRED AND 00/100 ($20,400.00) DOLLARS (the foregoing
   ------ -----------------------------------------------------
being hereinafter sometimes referred to as the "Base Rental"). The monthly Base
Rental shall be paid by Sublessee, together with Costs (as hereinafter defined),
in advance on the first day of each month, as an independent covenant to pay
rent, without advanced notice, demand, offset, abatement or deduction of any
kind. If the Term does not begin on the first day or end on the last day of a
calendar month, the Base Rental and Costs for that partial month shall be
prorated by multiplying the monthly Base Rental and Costs by a fraction, the
numerator of which is the number of days of the partial month included in the
Term and the denominator of which is the total number of days in the full
calendar month. All Rental (hereinafter defined) shall be payable in lawful
money of the United States to Sublessor at the office of Sublessor as follows:
Sterling Software (Western), Inc., 5800 Tennyson Parkway, Plano, Texas 75024,
-----------------------------------------------------------------------------
Attention: Director of Facilities, or to such other persons or at such other
---------------------------------
places as Sublessor may designate in writing from time to time. The sum of
                                                                ----------
Twenty Thousand Four Hundred and no/100 Dollars ($20,400.00) is due and shall be
--------------------------------------------------------------------------------
paid in advance by Sublessee to Sublessor upon the execution of this Sublease,
-----------------------------------------------------------------------------
which amount shall be applied to the Base Rental payment due on November 1,
1999. On before September 15, 1999, Sublessee shall pay Sublessor the sum of Ten
Thousand Eight Hundred Eighty and No/100
<PAGE>

Dollars ($10,880.00) as pro rata Base Rental for the period from September 15,
1999 through September 30, 1999. Sublessee's obligation to pay Base Rental and
Costs in accordance with the Sublease shall begin on the Commencement Date
regardless of whether (i) the move-in of Sublessee's furniture, fixtures,
machinery, equipment and personal property and construction of the Sublessee's
improvements is complete and/or (ii) Sublessee has actually occupied the
Subleased Premises at such time. For purposes of this Sublease, the term
"Rental" shall mean, collectively, Base Rental, Costs and all other sums payable
by Sublessee to Sublessor under this Sublease, all of which are hereby deemed
and designated as rent pursuant to the terms of this Sublease.

          4.2.  Costs. In addition to the Base Rental, Sublessee agrees to pay
                -----
Sublessor all Costs (as defined in the Prime Lease; hereinafter referred to as
"Costs") due under the Prime Lease on or before the dates when due under the
terms of the Prime Lease. Sublessor agrees to deliver to Sublessee copies of all
notice and statements received by Sublessor from Prime Lessor with respect to
the billing of such Costs. Additionally, Sublessee shall be solely responsible
for all telephone and utility costs for the Premises which are not included in
the Costs under the Prime Lease. All Costs (as defined in the Prime Lease),
telephone and utility costs which Sublessee is required to pay hereunder are
additional rentals, and should Sublessee fail to pay such Costs, telephone or
utility costs, Sublessor shall have the same remedies as Sublessor has for the
non-payment of Rental.

          4.3  Free Rent. Sublessor agrees, in consideration for Sublessor not
               ---------
removing any walls or touching up any paint in the Subleased Premises, to
provide Sublessee with a one time credit for thirty (30) days of free rent. Such
one time credit for said thirty (30) days of free rent shall total Twenty
Thousand Four Hundred and no/100 Dollars ($20,400.00) and shall be credited
against the installment of Rental due hereunder by Sublessee to Sublessor on
October 1, 1999.

     5.   Late Payment Interest Charges. All Rental and other amounts of money
          -----------------------------
payable by Sublessee to Sublessor under Section 4 or otherwise due from
Sublessee to Sublessor under this Sublease, shall be paid on or before the due
date thereof. In the event any installment of Base Rental, Costs, or other
charges to be paid by Sublessee hereunder is not paid when due, Sublessee, from
and after the fifth (5th) day after the date when due, shall pay interest on the
amount due equal to eighteen percent (18%) per annum, so long as said amount
remains unpaid (but in no event shall the amount of such late charge exceed an
amount based upon the highest legally permissible rate chargeable at any time by
Sublessor under the circumstances). Should Sublessee make a partial payment of
past due amounts, the amount of such partial payment shall be applied first to
reduce all accrued and unpaid interest charges, in order of their maturity, and
then to reduce all other past due amounts, in order of their maturity.
Acceptance by Sublessor of a late payment, and the cashing of a check, in an
amount less than that which is currently due shall in no way affect Sublessor's
rights under this Sublease and in no way be an accord and satisfaction. This
provision does not prevent Sublessor from declaring the non-payment of Base
Rental, Costs, or other charges to be paid hereunder when due an Event of
Default hereunder. Sublessee agrees to pay said late payment interest
immediately upon demand. It is acknowledged by the parties hereto that the late
payment by Sublessee to Sublessor of Rental or any other sums due hereunder will
cause Sublessor to incur costs not contemplated by this Sublease, the exact
amount of which would be extremely difficult and impractical to ascertain. Such
costs include, but are not limited to processing, clerical and accounting
charges, lost interest, and late charges which may be imposed on Sublessor by
the terms of the Prime Lease. All Rental and other amounts of money payable by
Sublessee to Sublessor under this Sublease shall be paid on or before the due
date thereof, and if not so paid, in addition to the above interest charge, a
late charge of five (5%) percent of the amount due (which late fee represents an
agreed upon charge for the administrative expense and burden suffered and
incurred by Sublessor as the result of such late payment and not payment for the
use of money) shall be due on the first (1st) day after such unpaid or
delinquent amount shall be due and unpaid. Sublessee acknowledges that the
charges under this Section are reasonable charges for damages Sublessor will
suffer as a result of the failure by Sublessee to make timely payments of
amounts due under this Sublease.

     6.   Use and Occupancy.
          -----------------

          6.1  Use. The Subleased Premises shall be used and occupied only by
               ---
Sublessee's employees for general industrial, warehousing and office purposes,
including, without limitation, research and development and assembly, and for no
other purpose.

          6.2  Compliance with Law.
               -------------------

               (a) Sublessee acknowledges and agrees that Sublessee is leasing
the Subleased Premises on an "AS IS," "WHERE IS," and "WITH ALL FAULTS" basis,
and subject to the Prime Lease. Sublessee accepts the Subleased Premises in
their existing condition, without representation or warranty, express or
implied, in fact or by law, and no representation, statement or warranty,
express or implied, has been made by or on behalf of Sublessor as to such
condition, or as to the use that may be made of said Subleased Premises. In no
event shall Sublessor be liable for any defect in the Subleased Premises
(whether latent or patent) or for any limitation on their use. All alterations,
decorations, installations, additions or improvements in or to the Subleased
Premises shall be made at Sublessee's sole cost and expense, shall be subject to
Prime Lessor's consent (if and to the extent any such matter if done by
Sublessor under the Prime Lease would be subject to Prime Lessor's consent) and
shall comply with all of the terms and conditions of the Prime Lease, including,
without limitation, Section 9 of the Prime Lease applicable to the making of
Alterations. Sublessee shall be responsible for replacing any damaged or stained
ceiling tiles in the Subleased Premises and may deduct the cost, not to exceed
One Thousand Five Hundred and no/100 Dollars ($1,500.00), of such replacement
from Sublessee's second month's rental payment upon providing Sublessor with
invoices from the contractors who performed such replacement which document the
completion of such ceiling tile replacement. Sublessor agrees, at its sole cost
and expense, prior to the Commencement Date, to have the carpets in the
Subleased Premises professionally steam cleaned, to provide full janitorial
service to the Subleased Premises, and to have its maintenance contractor
inspect the HVAC systems for the Subleased Premises and make such repairs as are
necessary to deliver the HVAC systems to Sublessee in good repair and working
order in accordance with the specifications for such equipment.

          (b) All alterations, additions, improvements or installations (herein
collectively referred to as "Alterations" or individually referred to as an
"Alteration") which may be made to the Subleased Premises by Sublessee, shall,
upon the expiration or sooner termination of the Term, by lapse of time or
otherwise, become the property of Sublessor and remain upon and be surrendered
with the Subleased Premises, unless the terms of the Prime Lease require any
Alterations of Sublessee to be removed at the end of the term of the Prime
Lease, in which case Sublessee shall remove such Alterations and restore all
damage caused by such removal at Sublessee's cost. Personal property of
Sublessee that shall remain in the Subleased Premises upon the expiration or
earlier termination of the Term shall be deemed abandoned, shall thereupon
become the property of Sublessor and Sublessor may dispose of such property any
way Sublessor sees fit without liability to Sublessee. At the expiration or
earlier termination of the Term, Sublessee shall, at Sublessee's sole cost and
expense, deliver possession of the Subleased Premises to Sublessor broom clean
and free of debris, ordinary wear excepted. Sublessee shall specifically have no
right to remove any personal property, fixtures, trade fixtures or other items
owned by Sublessor in or about the Subleased Premises. Notwithstanding any other
term or provision of this Sublease to the contrary, provided that no Event of
Default of Sublessee hereunder remains outstanding and uncured, Sublessee may
remove any personal property or trade fixtures purchased and installed by
Sublessee in the Subleased Premises.

          (c) Sublessee shall, at Sublessee's expense, comply promptly with all
applicable statutes, ordinances, rules, regulations, codes, orders, restrictions
of record, and requirements in effect during the Term or any part of the Term
hereof regulating the use of the Subleased Premises, including, without
limitation, the Americans With Disabilities Act of 1990 and all amendments,
rules and regulations promulgated in connection therewith, except to the extent
the Prime Lessor is expressly required by the terms of the Prime Lease to comply
with such statutes, ordinances, rules, regulations, codes, orders, restrictions
of record or requirements at Prime Lessor's cost. Sublessee shall not use or
permit the use of the Subleased Premises in any manner that will

                                      -3-
<PAGE>

tend to create waste, odors, noise, heat, cold, vibration or a nuisance, or
which shall tend to disturb Sublessor or other tenants of the Building.

          6.3  Condition of Subleased Premises. Sublessee hereby accepts the
               -------------------------------
Subleased Premises in their condition existing as of the date of the execution
hereof, subject to all applicable zoning, municipal, county and state laws,
ordinances, codes and regulations governing and regulating the use of the
Subleased Premises, and accepts this Sublease subject to all matters disclosed
hereby and by any exhibits attached hereto. Sublessee acknowledges that neither
Sublessor nor Sublessor's agents have made any representation or warranty as to
the suitability of the Subleased Premises or any improvements thereto for the
conduct of Sublessee's business.

          6.4  Compliance with Prime Lease.
               ---------------------------

               (a) Sublessee agrees that it will occupy the Subleased Premises
in accordance with the terms of the Prime Lease and will not suffer to be done
or omit to do any act which may result in a violation of or a default under any
of the terms and conditions of the Prime Lease, or render Sublessor liable for
any damage, charge or expense thereunder. Sublessee further covenants and agrees
to indemnify Sublessor against and hold Sublessor harmless from any claim,
demand, action, proceeding, suit, liability, loss, judgment, expense (including
attorneys' fees) and damages of any kind or nature whatsoever arising out of, by
reason of, or resulting from, Sublessee's failure to perform or observe any of
the terms and conditions of the Prime Lease or this Sublease. Any other
provision in this Sublease to the contrary notwithstanding, in addition to the
Base Rental and Costs, Sublessee shall pay to Sublessor as Rental hereunder, any
and all sums which Sublessor may be required to pay the Prime Lessor arising out
of, by reason of, or resulting from Sublessee's use or occupancy of the
Subleased Premises, Sublessee's failure to perform or observe one or more of the
terms and conditions of the Prime Lease or this Sublease, or arising out of a
request by Sublessee for additional Building services from Prime Lessor
(including, without limitation, charges associated with over standard electrical
charges or extra janitorial services requested by Sublessee).

               (b) Sublessee agrees that Sublessor shall not be required to
perform any of the covenants, agreements and/or obligations of Prime Lessor
under the Prime Lease and, insofar as any of the covenants, agreements and
obligations of Sublessor hereunder are required to be performed under the Prime
Lease by Prime Lessor thereunder, Sublessee acknowledges and agrees that
Sublessor shall be entitled to look to Prime Lessor for such performance.
Sublessor shall have no obligation to perform any work or services in the
Subleased Premises or to perform any other obligation of Prime Lessor under the
Prime Lease. In no event shall Sublessor be liable for the non-performance of
any obligation of the Prime Lessor tinder the Prime Lease, unless said non-
performance was caused by or resulted from the actions of Sublessor. Subject to
the other terms set forth below in this Section 6.4(b), Sublessor shall exercise
due diligence and take such action as may reasonably be indicated under the
circumstances, to secure such performance by Prime Lessor upon Sublessee's
written notice to Sublessor and request therefor (hereinafter referred as a
"Request for Prime Lessor's Performance") if Sublessor determines it is
reasonable and appropriate to do so. Sublessee agrees that it shall be the
responsibility of Prime Lessor to provide any such work and services and not
that of Sublessor. Sublessee shall not have the right to require or obtain
performance by Sublessor, and Sublessee shall have no claim against Sublessor by
reason of Prime Lessor's failure or refusal to comply with any of the terms of
the Prime Lease on its part to be performed. No such failure or refusal shall
constitute an eviction, actual or constructive, and Sublessee shall not be
entitled to cancel this Sublease or to any reduction or abatement of the rent
reserved herein. It is further agreed that Sublessor shall join with Sublessee
in any notice or demand that Prime Lessor perform and comply with its
obligations under the Prime Lease and that Sublessor shall, at Sublessee's
expense, cooperate generally with Sublessee in seeking such performance and
compliance on the part of Prime Lessor; provided, however, Sublessor shall not
be obligated to commence any legal action or proceeding against Prime Lessor
unless (i) no default of Sublessee remains outstanding and uncured under this
Sublease, (ii) Sublessee shall, in a written instrument acceptable to Sublessor,
indemnify, defend and hold Sublessor free and harmless of and from all claims,
demands, actions, proceedings, suits, liabilities, losses, judgments, expenses
(including reasonable attorneys' fees) and damages of any kind or nature
whatsoever which Sublessor may suffer or incur in connection with such legal
action or proceeding, and (iii) Sublessee shall provide

                                      -4-
<PAGE>

to Sublessor such security for said indemnity as Sublessor may in its sole and
absolute discretion deem appropriate.

               (c) If Sublessee asks Sublessor in writing to request Prime
Lessor to give its approval or consent under the Prime Lease in any situation
where such approval or consent is required hereunder or under the Prime Lease,
Sublessor agrees to request such approval or consent from Prime Lessor. However,
such request by Sublessor shall not be deemed to constitute the approval or
consent of Sublessor in any situation where Sublessor's approval or consent is
required hereunder or to impair, affect, waive or diminish in any way the right
and ability of Sublessor or refuse to give its approval or consent, either prior
to or subsequent to making such request. In making any such request of Prime
Lessor, Sublessor shall be acting solely for Sublessee in order to satisfy any
requirement of the Prime Lease that Sublessor request such consent from Prime
Lessor. In all provisions of the Prime Lease (under the terms thereof and
without regard to modification thereof for purposes of incorporation into this
Sublease) requiring the approval or consent of Prime Lessor, Sublessee shall be
required to obtain the approval or consent of Sublessor and Prime Lessor, and
Sublessor shall not unreasonably withhold or delay its approval or consent;
provided that if Prime Lessor shall have withheld its approval or consent in
accordance with the Prime Lease, in any instance in which such approval or
consent is so required, Sublessor's refusal to give its approval or consent in
such instance shall not be deemed unreasonable.

               (d)  If Sublessor receives the benefit of an abatement of the
rental due under the Prime Lease with respect to the Subleased Premises under
the terms of:

                    (i)  Section 10 of the Prime Lease and Section 29 of the
Addendum to the Prime Lease as a result of a destruction of all or part of the
Subleased Premises; or

                    (ii) Section 11 of the Prime Lease as a result of a
condemnation of all or part of the Subleased Premises;

then the Base Rental due under this Sublease shall abate for the same period of
time that the Prime Lessor abates Sublessor's Base Rental under the Prime Lease
with respect to the Subleased Premises. Sublessee shall not receive any
abatement pursuant to the terms of this Section 6.4(d) unless and until the
Prime Lessor provides Sublessor an uncontested abatement under one of the above-
referenced Sections with respect to the Subleased Premises. This Sublease shall
terminate upon the termination of the Prime Lease pursuant to Sections 10 or 11
of the Prime Lease and Section 29 of the Addendum to the Prime Lease. Sublessee
shall have no right to terminate this Sublease in the event of a destruction,
casualty or a condemnation, taking by eminent domain or deed in lieu thereof,
except upon termination of the Prime Lease with respect to the Subleased
Premises pursuant to Sections 10 and/or 11 of the Prime Lease and/or Section 29
of the Addendum to the Prime Lease. Sublessor agrees not to itself unilaterally
terminate the Prime Lease as it relates to the Subleased Premises, however, both
Sublessor and Sublessee are subject to the Prime Lessor's rights to terminate
the Prime Lease as provided in Sections 10 and 11 of the Prime Lease and Section
29 of the Addendum to the Prime Lease, or otherwise.

     7.   Prime Lease and Sublease Terms.

other under this Sublease shall be the same as the terms and conditions of the
Prime Lease except for those provisions of the Prime Lease which are directly

Sublessee does hereby expressly assume and agree to perform and comply with, for
the benefit of Sublessor and Prime Lessor each and every obligation of Sublessor
under the Prime Lease with respect to the Subleased Premises, except for those
provisions of the Prime Lease which are directly contradicted by this Sublease,
in which event the terms of this Sublease document shall control over the Prime
Lease.

               -----------
Section 7.5 hereof are hereinafter referred to as the "Sublessee's Assumed

          7.8  Maintenance of Prime Lease. Sublessor agrees to maintain the
               --------------------------
Prime Lease in existence, as it pertains to the Subleased Premises, during the
entire term of this Sublease, subject, however, to any earlier termination of
the Prime Lease without the fault or willful termination of the Sublessor, and,
upon written notice and request by Sublessee, to use its reasonable efforts as
specified in Section 6.4(b) above to cause Prime Lessor to comply with or
perform the Remaining Obligations. Notwithstanding the foregoing, Sublessor
shall not be required to institute any proceeding or action, at law or in
equity, against the Prime Lessor unless and until the requirements of Section

          7.9  Submissions to Prime Lessor. In all provisions of the Prime Lease
               ---------------------------
requiring Sublessor, as tenant, to submit, exhibit to, supply or provide Prime
Lessor with evidence, certificates or any other matter or thing, Sublessee shall
be required to submit, exhibit to, supply or provide, as the case may be, the
same to Sublessor and Prime Lessor. In any such instance, the Sublessor shall
reasonably determine if such evidence, certificate or other matter or thing
shall be satisfactory, provided that if the Prime Lessor shall deem such
evidence, certificate or other matter or thing unsatisfactory, Sublessor's
refusal to accept such evidence, certificate or other matter or thing, as
satisfactory to Sublessor shall not be deemed unreasonable.

          7.10 Sublessor's Representations. Sublessor represents to Sublessee,
               ---------------------------
based on the present actual knowledge of Sublessor and its employees, that as of
the date hereof:

               (a) Sublessor has not executed any sublease and/or prior
assignment of any of its rights under the Prime Lease with respect to the
Subleased Premises, which would adversely affect this Sublease;

               (b) No notices of default sent by Sublessor to Prime Lessor
remain outstanding and uncured with respect to any failure of the Prime Lessor
to perform the covenants and obligations on its parts to be performed and
observed under the Prime Lease;

               (c) Sublessor has received no written notices of default from the
Prime Lessor which remain outstanding and uncured, and no circumstances exist
that with the giving of notice under the Prime Lease, the passage of time, or
both would constitute an Event of Default on the part of Sublessor under the
Prime Lease; and

               (d) Sublessor has received no written notices of any violations
of law with respect to the Premises under the Prime Lease from any governmental
authority or any other person.

     8.   Taxes Payable By Sublessee. In addition to Base Rental, Costs and
          --------------------------
other charges to be paid by Sublessee hereunder, Sublessee shall reimburse
Sublessor upon demand, as Rental, for any and all taxes payable by Sublessor
(other than Sublessor's federal, state and local net income taxes, franchise,
gift, transfer, capital stock, estate or inheritance taxes) whether or not now
customary or within the contemplation of the parties hereto: (a) upon, measured
by or reasonably attributable to the cost or value of Sublessee's equipment,
furniture, fixtures and other personal property located in the Subleased
Premises or by the cost or value of any improvements made in or to the Subleased
Premises by Sublessee, regardless of whether title to such improvements shall be
in Prime Lessor, Sublessee or Sublessor (b) upon, measured by and directly
related to the monthly rental payable hereunder, including, without limitation,
any gross receipts, gross income tax or excise tax levied by any local
governmental authority, the State of California, the federal government or any
other governmental body with respect to the receipt of such rental; (c) upon or
with respect to the possession, leasing, operation, management, maintenance,
alteration, repair, use or occupancy by Sublessee of the Subleased Premises or
any portion thereof; or (d) upon this transaction or any document to which
Sublessee is a party creating or transferring an interest in the Subleased
Premises. In the event that it shall not be lawful for Sublessee so to reimburse
Sublessor, the monthly Base Rental and Costs payable to Sublessor under this
Sublease shall be revised to net Sublessor the same net Base Rental and Costs
after imposition of any such tax upon Sublessor as would have been payable to
Sublessor prior to the imposition of any such tax.

     9.   Assignment or Subletting. Sublessee, for itself, its successors and
          ------------------------
assigns, expressly covenants and agrees that it shall not assign, mortgage,
encumber or otherwise transfer any right or interest in this Sublease, nor
sublet, nor suffer or permit the Subleased Premises or any part thereof to be
used by others, without the prior written consent of Sublessor and Prime Lessor
in each instance, which consent by Sublessor shall not be unreasonably withheld
or delayed, and any such attempted assignment, mortgage, encumbrance, other
transfer or subletting without such consent shall be null and void and ab
                                                                       --
initio. The consent by Sublessor to an assignment or subletting shall not in any
------
way release or relieve Sublessee from any obligation or liability under this
Sublease, or in any way be construed to relieve Sublessee from obtaining the
express consent in writing of Sublessor and Prime Lessor to any further
assignment or subletting. Sublessee's right to further assign this Sublease or
to further sublet the Subleased Premises shall be subject to the provisions of

                                      -7-
<PAGE>

Section 13 of the Prime Lease. Sublessee agrees to pay Sublessor and Prime
Lessor all costs paid or incurred by them to review any sublease or assignment
proposed by Sublessee. If this Sublease is assigned, or if the Subleased
Premises or any part thereof is sublet or occupied by any person, firm or
corporation other than Sublessee, with the consent of Sublessor and Prime
Lessor, Sublessor may, upon any default by Sublessee, collect rent from the
assignee, subtenant or occupant and apply the net amount collected to the
Rental, but no such assignment, subletting, occupancy or collection shall be
deemed a waiver of this covenant or the acceptance of the assignee, subtenant or
occupant as a tenant, or a release of Sublessee from the future performance by
Sublessee of the covenants and agreements on the part of Sublessee herein
contained. Sublessee shall not be entitled to make, nor shall Sublessee make,
any claim, and Sublessee hereby waives any claims, for money damages (nor shall
Sublessee claim any money damages by way of set-off, counterclaim or defense)
based on any claim or assertion by Sublessee that Sublessor or Prime Lessor has
unreasonably withheld and/or delayed its consent or approval to a proposed
assignment or sub-subletting as provided for in this Section 9 or Section 13 of
the Prime Lease. Sublessee's sole and exclusive remedy shall be to enforce the
provisions of this Section 9 and Section 13 of the Prime Lease by an action for

     15.  Default and Remedies.
          --------------------

          15.1  Events of Default. Sublessee shall be in default under this
                -----------------
Sublease upon the occurrence of any one or more of the following events or
occurrences, each of which shall be deemed to be a material Event of Default:

                (i)   The failure by Sublessee to make any payment due Sublessor
under the terms of this Sublease with respect to Base Rental or Costs, within
three (3) days after Sublessee has been given written notice from Sublessor to
Sublessee specifying Sublessee's failure to make such payment. Sublessor shall
not be required to give written notice to Sublessee of any failure to make any
such payments more than two (2) times in any calendar year. After Sublessor has
given Sublessee the second written notice with respect to Sublessee's failing in
the payment of such amounts in any calendar year, thereafter the failure to pay
any such payment(s) during the remainder of the same calendar year shall mature
into a material Event of Default if such payment is not made by the date when
the same shall be due and payable; or

                (ii)  Sublessee fails to pay, when due, any other sum or amount
due and payable under this Sublease (other than Base Rental or Costs), or under
the Prime Lease provisions assumed by Sublessee pursuant to Paragraph 7.5
herein, and such failure continues for twenty-five (25) days after notice
thereof from Sublessor or Prime Lessor; or

                (iii) Sublessee fails to fully and punctually observe or perform
any of the terms, conditions, agreements or covenants of this Sublease (other
than the obligation to pay the sums described in subparagraphs 15. l(i) and (ii)
above) and such failure continues for twenty-five (25) days after notice thereof
from Sublessor provided, however, that if such failure is an non-monetary
failure and cannot reasonably be cured within such twenty-five (25) day period,
no Event of Default shall exist hereunder if Sublessee begins to cure such
default within such twenty-five (25) day period and diligently, continuously and
in good faith pursues said cure to completion within one hundred and ten (110)
days after such notice; or

                (iv)  Sublessee fails to fully and punctually observe or perform
any of the terms or covenants of the Prime Lease assumed by Lessee pursuant to
Paragraph 7.5 above and such failure continues for twenty-five (25) days after
notice thereof from Sublessor or Prime Lessor, provided, however, that if such
failure is a non-monetary failure and cannot reasonably be cured within such
twenty-five (25) day period, no Event of Default shall exist hereunder if
Sublessee begins to cure such default within such twenty-five (25) day period
and diligently, continuously and in good faith pursues said cure to completion
within sixty (60) days after such notice; or

                (v)   Sublessee fails to eliminate any (a) odor, vibration,
noise, heat, cold or nuisance emanating from the Subleased Premises, which
disturbs Sublessor or other tenants of the Building, (b) waste, or (c) violation
of any legal requirement, caused by the act or omission of Sublessee, it agents,
employees, invitees, sublessees, assignees, contractors or subcontractors, and
such failure continues for five (5) days after notice thereof from Sublessor or
Prime Lessor; or

                (vi)  The filing or execution or occurrence of: (a) a petition
by or against Sublessee or any guarantor of this Sublease in bankruptcy or
seeking any reorganization, arrangement, composition, readjustment, liquidation,
dissolution or similar relief under any provision of the present or any future
bankruptcy act or any other present or future federal, state or other bankruptcy
or insolvency statute or law, provided however that if an involuntary bankruptcy
petition is filed against Sublessee or any guarantor of this Sublease, no Event
of Default shall occur if said involuntary bankruptcy petition is dismissed
within sixty (60) days of the date such petition was initially filed, (b)
adjudication of Sublessee or any guarantor of this Sublease as a bankrupt or
insolvent, insolvency in the bankruptcy or equity sense, (c) an assignment by
Sublessee or any guarantor of this Sublease for the benefit of creditors, (d) a
petition or other proceeding by or against Sublessee or any guarantor of this
Sublease, or the appointment of a trustee, receiver, guardian, conservator or
liquidator with respect to any portion of Sublessee's property or property of
any guarantor of this Sublease, (e) any levy, execution or attachment against
Sublessee or any guarantor of this Sublease, or (f) any transfer or passage of
any interest of Sublessee under this Sublease by operation of law; or

                (vii)  Sublessee causes any lien to be placed on the Subleased
Premises or the Building.

          15.2  Remedies upon Default.
                ---------------------

                (i)    If Sublessor elects pursuant to Section 15.1 to declare
an Event of Default, then Sublessor shall, during the continuation of said Event
of Default, have the right to declare a forfeiture of this Sublease as provided
in Section 1161 of the California Code of Civil Procedure, by giving Sublessee
an additional notice three (3) days prior to the effectiveness of said
forfeiture, and provided that such Sublessor's notice states such an election,
Sublessee's right to possession shall terminate and this Sublease shall
terminate, unless on or before the date specified in such notice, all arrears of
rent and all other sums specified in the initial notice of default and payable
by Sublessee under this Sublease shall have been paid by Sublessee and all
uncured breaches of this Sublease by Sublessee which were specified in the
initial notice of default shall have been fully remedied. Upon such termination,
Sublessor 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:

          (a)   In the event of any such termination of this Sublease, Sublessor
may then or at any time thereafter by judicial process, re-enter the Subleased
Premises and remove therefrom all persons and property and again repossess and
enjoy the Subleased Premises, without prejudice to any other remedies that
Sublessor may have by reason of such Event of Default and termination.

          (b)   In the event of any such termination of this Sublease, and in
addition to any other rights and remedies Sublessor may have, Sublessor shall
have all of the rights and remedies of a landlord provided by Section 1951.2 of
the California Civil Code. The amount of damages which Sublessor may recover in
the event of such termination shall include, without limitation, (1) 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 rental loss that
Sublessee proves could be reasonably avoided for the same period, (2) all
reasonable legal expenses and other reasonable related costs incurred by
Sublessor as a consequence of Sublessee's default, (3) all reasonable costs
incurred by Sublessor in restoring the Subleased Premises to good order and
condition, or in remodeling, renovating or otherwise preparing the Subleased
Premises for reletting, and (4) all reasonable costs (including, without
limitation, any commercially reasonable brokerage commissions) incurred by
Sublessor in reletting the Subleased Premises.

          (c)   After terminating this Sublease, Sublessor may remove any and
all personal property located in the Subleased Premises and place such property
in a public or private warehouse or elsewhere at the sole cost and expense of
Sublessee. In the event that Sublessee 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, Sublessor may sell any or all thereof at a public or private
sale in such manner and at such times and places as Sublessor in its reasonable
discretion may deem proper, without any further notice to or demand upon
Sublessee. Sublessee waives all claims for damages -J that may be caused by
Sublessor's removing or storing or selling Sublessor's furniture, fixtures,
machinery and equipment as herein provided; or

                (ii)  In the event of the occurrence of any of the events
specified in Section 15.1(vi)(a), (b) or (c) of this Sublease, if Sublessor
shall not choose to exercise, or by law shall not be able to exercise, its
rights hereunder to terminate this Sublease, then, neither Sublessee, as debtor-
in-possession, nor any trustee or other person (collectively, the "Assuming
Sublessee") shall be entitled to assume this Sublease unless on or before the
date of such assumption, the Assuming Sublessee (a) cures, or provides adequate
assurance that the Assuming Sublessee will promptly cure, any existing default
under this Sublease, (b) compensates, or provides adequate assurance that the
Assuming Sublessee will promptly compensate Sublessor 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 Sublease. For purposes of this Section 15.2(ii), "adequate assurance" of
such cure, compensation or future performance shall be effected by the
establishment of an escrow fund for the amount at issue or by bonding; or

                                      -11-
<PAGE>

                (iii)    Continuation After Default. If an Event of Default
                         --------------------------
exists under this sublease and Sublessee has abandoned the Subleased Premises,
Sublessor shall also have the remedy described in California Civil Code Section
1951.4 (Sublessor may continue this Sublease in effect after Sublessee has
breached this Sublease and abandoned the Subleased Premises and recover rent as
it becomes due; provided, however that Sublessee has the right to sublet or
assign this Sublease, subject only to the limitations set forth in Section 9
hereof). Acts of maintenance or preservation or efforts to relet the Subleased
Premises or the appointment of a receiver upon initiative of Sublessor to
protect Sublessor's interest under this Sublease shall not constitute a
termination of Sublessee's right to possession; or

                (iv)     Without liability to Sublessee or any other party and
without constituting a constructive or actual eviction, suspend or discontinue
furnishing or rendering to Sublessee any property, material, labor, utilities or
other service, wherever Sublessor or Prime Lessor is obligated to furnish or
render the same so long as Sublessee is in default under this Sublease; or

                (v)      Allow the Subleased Premises to remain unoccupied and
collect rent from Sublessee as it comes due; or

                (vi)     The remedies provided for in this Sublease are
cumulative and are in addition to any other remedies available to Sublessor at
law or in equity by statute or otherwise.

          15.3  No Election of Remedies. Sublessor's pursuit of any remedy or
                -----------------------
remedies, including without limitation, any one or more of the remedies stated
in the foregoing Section 15.2 above, shall not (i) constitute an election of
remedies or preclude pursuit of any other remedy or remedies provided in this
Sublease or any other remedy or remedies provided by law or in equity,
separately or concurrently or in any combination, or (ii) serve as the basis for
any claim of constructive eviction, or allow Sublessee to withhold any payments
under this Sublease.

          15.4  Application of Funds. If this Sublease shall terminate as a
                --------------------
result of or while there exists a default hereunder, any funds of Sublessee held
by Sublessor may be applied by Sublessor to any damages payable by Sublessee
(whether provided for herein or by law) as a result of such termination or
default.

          15.5  Subsequent Actions. Neither the commencement of any action or
                ------------------
proceeding, nor the settlement thereof, nor entry of judgment thereon shall bar
either party from bringing subsequent actions or proceedings from time to time,
nor shall the failure to include in any action or proceeding any sum or sums
then due be a bar to the maintenance of any subsequent actions or proceedings
for the recovery of such sum or sums so omitted.

          15.6  Rent. All sums which Sublessee has anywhere in this Sublease
                ----
agreed to pay to or reimburse Sublessor, whether designated as Costs, additional
rent or otherwise, and whether for operating costs, telephone, utilities, taxes,
sewer rents or rates, water rents or rates, insurance premiums, cost of repairs
or otherwise, shall be deemed additional rent reserved in this Sublease, and
Sublessor shall have for the collection thereof all the remedies available for
the collection of unpaid rents.

          15.7  Sublessor's Right of Entry. Sublessor and its agents, servants,
                --------------------------
and employees may, but shall have no obligation to, upon the occurrence of an
(i) emergency or (ii) an Event of Default under Subsection 15.1 above, enter the
Premises without any further notice to Sublessee, without any charge, liability
or abatement of Rental, for purposes of taking any and all actions Sublessor
deems necessary to avoid damage or injury to persons or property and/or to
remedy any Event of Default under Subsection 15.1.

          15.8  Additional Remedies Under Prime Lease. If any event described in
                -------------------------------------
Section 14 of the Prime Lease shall occur in respect of Sublessee, the Subleased
Premises or Sublessee's property, or if Sublessee shall default in the payment
of any Rental or other amounts due hereunder or default in the performance or
observance of any of the terms, covenants and conditions of this Sublease or of

Sublessee's right to use or occupancy of the Subleased Premises pursuant to the
terms of this Sublease.

     24.  Force Majeure. Sublessor shall be excused for the period of any delay

all entities having taxing or assessment authority by law or by virtue of any
recorded instrument binding on the owner of the Premises.

     8.3.  Insurance. Tenant shall pay its percentage share of all premiums for
           ---------
such insurance, as shall be carried by Landlord to its full replacement cost
value excluding the cost of excavations, foundations and footings, against all
perils included in the classifications of fire, extended coverage, vandalism,
malicious mischief, special extended perils, and all-risk sprinkler leakage;
against loss of Building rents, property taxes, and insurance costs for a period
of not more than six months; against personal injury and property damage
liability to the extent such insurance is not provided by Tenant under this
Lease; against such other hazards as are then normally insured against by owners
of commercial buildings of the sort containing the Premises.

     8.4.  Percentage Share. Tenant's percentage share of the costs described
           ----------------
above shall be the percentage stated in the Lease Summary, or, if no percentage
is there stated, shall be determined by the square footage of the Premises
divided by the square footage of the Building. However, if Tenant utilizes more
than its proportionate share of the Common Area, for parking or other purposes,
or more than a normal amount of any utility service, then Landlord may equitably
increase Tenant's percentage share of costs associated with those items to
account for such additional usage. Tenant's percentage share of property taxes
may also be equitably adjusted by Landlord to take account of any
disproportionate burden imposed by special improvements or valuations relating
to other portions of the building or to other buildings on the tax parcel, which
adjustment may raise or lower Tenant's percentage share; valuation data
contained on the tax assessor's worksheets, if available, shall conclusively
determine the manner in which any equitable adjustment is to be made. Tenant
shall have the right to review the tax assessor's worksheets as a method of
auditing Landlord's allocations of property taxes to be paid by Tenant.

     8.5.  Payment. At Landlord's election, Tenant shall pay its percentage
           -------
share of such costs to Landlord either (i) when incurred, on the basis on
Landlord's periodic billings, or (ii) monthly in advance, on the first day of
each calendar month, and the monthly amount shall be determined by Landlord's
then-current estimate of the average monthly costs. If periodic billings are
utilized, Tenant's payment shall be due ten days after the billing date.
Landlord's initial estimate of the average monthly cost may be stated in the
Lease Summary. Periodically, but not less frequently than annually, Landlord
will provide Tenant with an accounting of all such costs for the preceding
period, and an appropriate sum will be credited or debited against Tenant's next
monthly rental payment so as to equalize Tenant's actual payments and Tenant's
actual share of costs for the period. Landlord may revise its monthly cost
estimate, and provide Tenant with an accounting for the previous period, at any
time during the lease term. If the lease term includes only a portion of a
taxing or insured period, then Tenant shall pay a pro rata portion of the total
property taxes or insurance premiums, based upon the number of days in the lease
term that are included in the taxing or insured period; however, Tenant shall
pay the entire amount of any property tax, for the tax year in which this Lease
terminates (or for the succeeding tax year if this Lease terminates after the
lien date for that tax year), levied on or attributable to improvements or
property that is to be removed from the Premises by Tenant prior to or at the
end of the lease term. If the Lease terminates before the property taxes for the
then-current fiscal year are known, the amount of the tax shall be reasonably
estimated on the basis of the best available information on current assessments
a and tax rates or, if no such information is available, shall be projected at
the same rate as was imposed for the last previous taxing period, plus 2%.

  9.  Alterations.
      -----------

     9.1.  Tenant Work. Tenant shall make no alteration, addition, or utility
           -----------
installation ("Changes") on or to the Premises without Landlord's prior written
consent. In making approved Changes, Tenant shall comply with all applicable
building code requirements. Unless Landlord has specifically waived this
provision in writing prior to the installation of Changes, such Changes (i)
shall be removed from the Premises, and all damage resulting from such removal
repaired by Tenant, prior to the end of the lease term, or (ii) shall remain on
the Premises at the end of the lease term and become the property of Landlord,
at Landlord's election. If Landlord does not notify Tenant, at least three
months prior to the end of the lease term, of its election to have Changes
remain on the Premises, then Landlord shall thereby have elected to require
Tenant to remove such Changes. In making all Changes, Tenant shall hold Landlord
harmless from mechanics' liens and all other liability resulting therefrom.

     9.2.  Landlord Work and Entry. Upon execution of this Lease, or at such
           -----------------------
later time as is feasible and consistent with the terms hereof, Landlord shall
commence construction of any improvements depicted or described as Landlord work
on an Exhibit or Addendum to this Lease. Construction of such improvements shall
be pursued to completion with reasonable diligence, subject to delays for
reasons beyond Landlord's reasonable control ("Unexpected Events"). Unexpected
Events include, for example, labor difficulties, inclement
<PAGE>

weather, rationing or other governmental controls, and shortages of materials or
services.

All such improvements shall become part of the Premises and remain thereon at
the termination of the Lease. Landlord may enter the Premises at any time for
inspection purposes, and may enter during normal business hours to show the
Premises to prospective Tenants in the last 180 days of the lease term
accompanied by employers of Tenant.

  10.  Damage. If any structural portion of the Premises that Landlord is
       ------
obligated to maintain is damaged or destroyed by any cause, if such damage is
insured against, and if the insurance proceeds are available for rebuilding,
then this Lease will not terminate and Landlord will cause such damage to be
repaired with reasonable diligence, subject to delays in the disbursement of
insurance proceeds and Unexpected Events. Landlord's obligation in this regard
shall be enforceable by Tenant only if such damage interferes with Tenant's
reasonable occupancy of the Premises. Tenant's rent will abate to the extent
that the damage and repair period interfere with Tenant's use of the Premises.
See Paragraph 29.0 of Addendum. If Landlord elects to repair, rent will abate in
the manner described above; other than the obligation to repair stated above,
Landlord shall have no liability to Tenant on account of the damage.

  11.  Condemnation. If there is a taking by eminent domain or a transfer under
       ------------
threat thereof of (i) the entire Premises, or (ii) so much of the Premises, for
the balance of the lease term, as prevents the continued reasonable conduct of
Tenant's business thereon, then this Lease shall terminate as of the date that
possession of the condemned premises is delivered to the condemnor. No other
such taking or transfer shall terminate this Lease. All condemnation proceeds
shall be the property of Landlord, excepting only such portion thereof as is
designated by the condemnor as compensation for Tenant's moving expenses, of
Tenant's goodwill, or for Tenant's trade fixtures and improvements to the
Premises actually owned by Tenant.

  12.  Liability.
       ---------

     12.1.  Insurance. Tenant shall, at its expense, maintain in force during
            ---------
the lease term a combined single limit policy of bodily injury and property
damage insurance, having a liability limit of not less than One Million Dollars
($1,000,000), with contractual liability endorsement, insuring Landlord and
Tenant against all liability arising out of the owner ship, use, occupancy, or
maintenance of the Premises and appurtenant areas. Such insurance shall be
endorsed as primary and non-contributing, as to any policy carried by Landlord.
Tenant will deliver to Landlord a certificate evidencing such insurance and
providing that the insurance will not be cancelled except on at least 30 days
notice to Landlord.

     12.2.  Indemnity. Tenant shall indemnify Landlord and hold it harmless from
            ---------
all claims, demands, liabilities, and expenses, including attorney's fees,
arising out of Tenant's use of the Premises or from any acts permitted by Tenant
on the Premises, excluding claims or actions based upon Landlord's active
negligence or willful misconduct.

     12.3. Waiver of Liability (No Subrogation). To the extent allowable by the
           ------------------------------------
applicable insurance without reduction of coverage, Landlord and Tenant hereby
waive all rights of recovery against the other for loss or damage that is
compensable by insurance then in force or required by this Agreement.

  13.  Transfer.
       --------

     13.1  Transfer by Tenant. Tenant shall not assign, sublet, or otherwise
           ------------------
transfer, or permit a transfer of, all or any portion of its interest in this
Lease, the Premises, or of a controlling interest in any Tenant entity, without
Landlord's prior written consent, which shall not be unreasonably withheld. No
such consent shall relieve Tenant of any liability under this Lease, nor shall
it constitute consent to any further transfer. As a condition of such consent,
the transferee must assume all of Tenant's liabilities hereunder.

     13.2. Transfer by Landlord. The liability of Landlord hereunder shall
           --------------------
exist only in respect to the period that Landlord is the owner of the Premises,
but all of Landlord's obligations shall run with the land and be binding upon
all subsequent owners thereof. Upon any transfer of Landlord's interest in the
Premises, and notification thereof to Tenant, Landlord shall be relieved of all
liability hereunder except such as may have accrued prior to the transfer
provided transferee agrees to assume Landlord's obligations under this Lease.

  14.  Default.
       -------

     14.1  Events. The occurrence of any of the following events shall
           ------
constitute a material breach of this Lease and default by Tenant:

to Tenant, in the manner described in Section 1162 of the California Code of
Civil Procedure, of written notice of default;

       14.1.2. Failure by Tenant to perform any nonmonetary obligation under
this Lease where such failure continues for more than thirty days or after
receipt of written notice from Landlord, the failure cannot reasonably be cured
within thirty days, for a period exceeding the time within which such failure
could be cured with reasonable diligence

       14.1.3. A general assignment by Tenant for the benefit of creditors; the

either before or after the execution of this Lease.

     14.2  Remedies. After any breach or default by Tenant, Landlord shall have
           --------
all, rights and remedies afforded by law, including but not limited to the
following:
<PAGE>

       14.2.1. If Tenant's right to possession is expressly terminated in
writing by Landlord because of such breach, Landlord may recover from Tenant
such damages as may be allowed under the laws of California, with interest at
the rate specified in paragraph 17.1, including the worth at the time of the
award of the amount by which the unpaid rent, for the balance of the term after
the time of the award, exceeds the amount of such rental loss that the Tenant
proves could have been reasonably avoided, as discounted to the then present
value at a rate equal to one percent (1%) over the discount rate of the Federal
Reserve Bank of San Francisco at the time of the award.

       14.2.2. Without terminating Tenant's right to possession, Landlord may
enforce all of its rights and remedies under this Lease, including the right to
recover rent as it becomes due. For purposes of this provision, any reletting of
the Premises for a term of less than the unexpired term of this Lease or any
reletting of a portion of the Premises shall, at Landlord's option, be deemed to
terminate the Tenant's right to possession only with respect to such portion of
the unexpired term or such portion of the Premises as is the subject of such
reletting.

       14.2.3. Landlord may cause a receiver to be appointed to take possession
of the Premises and all of Tenant's property thereon to protect Landlord's
interest therein.

  15.  Subordination. At the option of the holder of any security interest
       -------------
encumbering the Premises, this Lease shall be either prior to, or subordinate
to, the lien of such security interest, provided that subordination to a
security interest created after execution of this Lease shall occur only if the
security holder agrees in writing that Tenant's occupancy of the Premises will
not be disturbed by such security holder, or its successor in interest, so long
as Tenant is not in default in the performance of its obligations hereunder.

  16. Tenant Statements.
      -----------------

     16.1  Offset. At the request of any prospective purchaser or encumbrancer
           ------

time as required, within ten days after notice from Landlord, execute a written
statement certifying that, to the best of Tenant's knowledge, (i) this Lease is
then unmodified and is in effect, (ii) no rent other than that for the current
month has been paid in advance, (iii) Landlord is not  then in default in the
performance of any of its obligations, or specifying the manner in which any of
said matters is untrue. Tenant's failure to execute such written statement
within the time required shall constitute an admission by Tenant, which may be
relied upon by such person, that this Lease is then in effect without
modification, that no advance rent has been paid, and that Landlord is not then
in default.

     16.2.  Occupancy Certificate. Upon accepting occupancy of the Premises,
            ---------------------
Tenant will, if required by any mortgagee or prospective mortgagee of the
Premises, complete, execute, and deliver to Landlord a certificate reflecting
Tenant's acceptance of the Premises, in such reasonable form as may be required

     17.1.  Monetary Payments. Any monetary payment that is required by this
            -----------------
Lease and is not made by Tenant When due shall thereafter bear interest at the
maximum rate as permitted by law.  No acceptance by Landlord of any monetary
payment shall constitute a waiver by Landlord of any default by Tenant
hereunder.

     17.2.  Quiet Enjoyment. So long as Tenant is not in default hereunder,
            ---------------
Landlord warrants to Tenant the quiet possession of the Premises throughout the

                ---------------
computer room as depicted on the attached Exhibit B. The computer room shall

reimbursement of a portion of the cost of constructing the computer room in
accordance with Paragraph 21.0 of this Addendum, shall cover the cost of the
computer floor and Halon system. Therefore, Tenant shall retain ownership of the

items and repair any damage to the Premises caused by such removal at Tenant's
sole expense upon expiration of this Lease or extension thereof.

     29.0 Damage: If the damage referred to in Paragraph 10 of the Lease is not
          ------
insured against, or the available insurance proceeds are insufficient for the

the cost of repair is greater than 5% of the replacement cost of the building,
Landlord may, at its option, exercised by notice to Tenant within thirty days of
the date that Landlord acquires knowledge of the damage, elect either to

          ---------
continuing throughout the term of this Lease, including all extension periods,
Tenant shall not be liable for, and Landlord shall indemnify and defend Tenant,
its officers, directors, employees, shareholders, agents and representatives, or
any of them, and the successors and assigns of such parties (collectively
"Tenant Indemnitiees"), from and against any and all claims damages,
liabilities, Judgments and expenses (including attorneys' fees and other costs),
for injury to persons, loss of life or damage to property occurring within,
around or adjacent to the Premises, and arising directly or indirectly out of
Landlord's construction of the Premises, Landlord's failure to perform any of
its obligations under this Lease, or any act of or failure to act by Landlord or
any agent or representative of Landlord while on the Premises; provided however,
Landlord shall have no liability for any injury, loss of life or damage to
property occurring in or about the Premises due to the sole negligence or
willful act or failure to act of Tenant, its partners, agents, contractors,
officers, directors, employees, shareholders or invitees. Landlord's liability
under this Paragraph shall be reduced by the net proceeds of any insurance
carried by Landlord to the extend such proceeds are applied toward payment of
such claims, damages, expenses, liabilities and judgments. Notwithstanding the

otherwise agreed in writing by Landlord, the Lease Commencement Date shall be
deemed to have occurred on such sooner date, and Tenant shall be obligated to
perform all its obligations under this Lease, including the obligation to pay
rent, from that sooner date.

                                  ARTICLE 3:
                   RENT, LATE CHARGES AND SECURITY DEPOSITS

         3.1 BASE MONTHLY RENT: Commencing on the Lease Commencement Date (as
determined pursuant to Article 2.3 above) and continuing throughout the Lease
Term, Tenant shall pay to Landlord, without prior demand therefore, in advance
on the first day of each calendar month, as base monthly rent, the amount set
forth as "Base Monthly Rent" in Article 1 (the "Base Monthly Rent").

         3.2 ADDITIONAL RENT: Commencing on the Lease Commencement Date (as
determined pursuant to Article 2.3 above) and continuing throughout the Lease
Term, in addition to the Base Monthly Rent, Tenant shall pay to Landlord as
additional rent (the "Additional Rent") the following amounts:

         A. An amount equal to all Property Operating Expenses (as defined in
Article 13) incurred by Landlord. Payment shall be made by whichever of the
following methods (or combination of methods) is (are) from time to time
designated by Landlord:

                  (1) Landlord may bill to Tenant, on a periodic basis not more
frequently than monthly, the amount of such expenses (or group or expenses) as
paid or incurred by Landlord, and Tenant shall pay to Landlord the amount of
such expenses within ten days after receipt of a written bill therefore from
Landlord; and/or

                  (2) Landlord may deliver to Tenant Landlord's reasonable
estimate of any given expense (such as Landlord's Insurance Costs or Real
Property Taxes), or group of identified expenses, which it reasonably
anticipates will be paid or incurred for the ensuing calendar or fiscal year, as
Landlord may determine, and Tenant shall pay to Landlord an amount equal to the
estimated amount of such expenses for such year in equal monthly, installments
during such year with the installments of Base Monthly Rent.

                  (3) Landlord reserves the right to change from time to time
the methods of billing Tenant for any given expense or group of expenses or the
periodic basis on which such expenses are billed.

         B. Landlord's share of the consideration received by Tenant upon
certain assignments and sublettings as required by Article 7;

         C. Any legal fees and costs that Tenant is obligated to pay or
reimburse to Landlord pursuant to Article 13; and

         D. Any other charges or reimbursements due Landlord from Tenant
pursuant to the terms of this Lease other than late charges and interest on
defaulted rent.

         3.3 YEAR-END ADJUSTMENTS: If Landlord shall have elected to bill Tenant
for the Property Operating Expenses (or any group of such expenses) on an
estimated basis in accordance with the provisions of Article 3.2A(2) above,
Landlord shall furnish to Tenant within three months following the end of the
applicable calendar or fiscal year, as the case may be, a statement setting
forth (i) the amount of such expenses paid or incurred during the just ended
calendar or fiscal year, as appropriate, and (ii) the amount that Tenant has
paid to Landlord for credit against such expenses for such period. If Tenant
shall have paid more than its obligation for such expenses for the stated
period, Landlord shall at Tenant's election, either (i) credit the amount of
such overpayment toward the next ensuing payment or payments of Additional Rent
that would otherwise by due or (ii) refund in cash to Tenant the amount of such
overpayment. If such year-end statement shall show that Tenant did not pay its
obligation for such expenses in full, then Tenant shall pay to Landlord the
amount of such underpayment within ten days from Landlord's billing of same to
Tenant. The provisions of this Article shall survive the expiration or sooner
termination of this Lease.

         3.4 LATE CHARGE AND INTEREST ON RENT IN DEFAULT: Tenant acknowledges
that the late payment by Tenant of any monthly installment of Base Monthly Rent
will cause Landlord to incur certain costs and expense not contemplated under
this Lease, the exact amounts of which are extremely difficult or impractical to
fix. Such costs and expenses will include, without limitation, administration
and collection costs and processing and accounting expenses. Therefore, if any
installment of Base Monthly Rent is not received by Landlord from Tenant within
six calendar days after Tenant's receipt of written notice from Landlord that
the same becomes due, Tenant shall immediately pay to Landlord a late charge in
an amount equal to the amount set forth in Article 1 as the "Late Charge
Amount", and if any Additional Rent is not received by Landlord within 10
calendar days after Tenant's receipt of written notice from Landlord that same
becomes due, Tenant shall immediately pay to Landlord a late charge in an amount
equal to 5% percent of the Additional Rent not so paid. Landlord and Tenant
agree that this late charge represents a reasonable estimate of such costs and
expenses and is fair compensation to Landlord for the anticipated loss Landlord
would suffer by reason of Tenant's failure to make timely payment. In no event
shall this provision for a late charge be deemed to grant to Tenant a grace
period or extension of time within to pay any rental installment or prevent
Landlord from exercising any right or remedy available to Landlord upon Tenant's
failure to pay each rental installment due under this Lease when due, including
the right to terminate this Lease. If any rent remain delinquent for a period in
excess of 20 calendar days, then, in addition to such late charge, Tenant shall
pay to Landlord interest on any rent that is not so paid from said day at the
then maximum rate of interest not prohibited or made usurious by Law until paid.

         3.5 PAYMENT OF RENT: All rent shall be paid in lawful money of the
United States, without any abatement, reduction or offset for any reason
whatsoever, to Landlord at such address as Landlord may designate from time to
time. Tenant's obligation to pay Base Monthly Rent and all Additional Rent shall
be appropriately prorated at the commencement and expiration of the Lease Term.
The failure by Tenant to pay any Additional Rent as required pursuant to this
Lease when due shall be treated the same as a failure by Tenant to pay Base
Monthly Rent when due, and Landlord shall have the same rights and remedies
against Tenant as Landlord would have if Tenant failed to pay the Base Monthly
Rent when due.

         3.6 PREPAID RENT: Concurrent with the execution of this Lease, Tenant
shall pay to Landlord the amount set forth in Article I as "First Month's
Prepaid Rent" as prepayment of rent for credit against the first installment(s)
of Base Monthly Rent due hereunder. Additionally, Tenant has paid to Landlord
the amount set forth in Article I as "Last Month's Prepaid Rent" as prepayment
of rent for credit against the last installment(s) of Base Monthly Rent due
hereunder, subject, however, to the provisions of Article 3.7 below.

         3.7 SECURITY DEPOSIT: Concurrent with the execution of this Lease,
Tenant shall deposit with Landlord the amount set forth in Article 1 as the
"Security Deposit" as security for the performance by Tenant of the terms of
this Lease to be performed by Tenant, and not as prepayment of rent. Landlord
may apply such portion or portions of the Security Deposit as are reasonably
necessary for the following purposes: (i) to remedy any default by Tenant in the
payment of Base Monthly Rent or Additional Rent or a late charge or interest on
defaulted rent; (ii) to repair damage to the Leased Premises, the Building or
the Outside Areas caused by Tenant; (iii) surrendered in the condition required
pursuant to the provisions of Article 2; and (iv) to remedy any other default of
Tenant to the extent permitted by Law including, without limitation, paying in
full on Tenant's behalf any sums claimed by materialmen or contractors of Tenant
to be owing to them by Tenant for work done or improvements made at Tenant's
request to the Leased Premises. In this regard, Tenant hereby waives any
restriction on the uses to which the Security Deposit may be applied as
contained in Section 1950.7(c) of the California Civil Code and/or any successor
statute. In the event the Security Deposit or any portion thereof is so used,
Tenant shall pay to Landlord, promptly demanded within 10 days following
Tenant's receipt of written notice an amount in cash sufficient to restore the
Security Deposit to the full original sum. If Tenant fails to promptly restore
the Security Deposit and if Tenant shall have paid to Landlord any sums as "Last
Month's Prepaid Rent", Landlord may, in addition to any other remedy Landlord
may have under this Lease, reduce the amount of Tenant's Last Month's Prepaid
Rent by transferring all or portions of such Last Month's Prepaid Rent to
Tenant's Security Deposit until such Security Deposit is restored to the amount
set forth in Article 1. Landlord shall not be deemed a trustee of the Security
Deposit. Landlord may use the Security Deposit in Landlord's ordinary business
and shall not be required to segregate it from its general accounts. Tenant
shall not be entitled to any interest on the Security Deposit. If Landlord
transfer the Building or the Property during the Lease Term, Landlord may pay
the Security Deposit to any subsequent owner in conformity with the provisions
of Section 1950.7 of the California Civil Code and/or any successor statute, in
which event the transferring landlord shall be released from all liability for
the return of the Security Deposit provided that such Transferee assumes in
writing the obligation of Landlord under this Lease. Tenant specifically grants
to Landlord (and Tenant hereby waives the provisions of California Civil Code
Section 1950.7 to the contrary) a period of 30 days following a surrender of the
Leased Premises by Tenant to Landlord within which to return the Security
Deposit (less permitted deductions) to Tenant, it being agreed between Landlord
and Tenant that 30 days is a reasonable period of time within which to inspect
the Leased Premises, make required repairs, receive and verify workmen's
billings therefore, and prepare a final accounting with respect to such deposit.
In no event shall the Security Deposit, or any portion thereof, be considered
prepaid rent.

under this Lease or at Law, perform such maintenance or make such repairs and
charge to Tenant, as Additional Rent, the costs so incurred by, Landlord for
same. All glass within or a part of the Leased Premises, both interior and

Tenant's name.

         6.1 BY TENANT: Tenant shall not make any alterations to or
modifications of the Leased Premises or construct any improvements within the
Leased Premises until Landlord shall have first approved, in writing, the plans

All such modifications, alterations or improvements, once so approved, shall be
made, constructed or installed by Tenant at Tenant's expense (including all
permit fees and governmental charges related thereto), using a licensed
contractor first approved by Landlord, in substantial compliance with the
Landlord approved plans and specifications therefore. All work undertaken by
Tenant shall be done in accordance with all Laws and in a good and workmanlike
manner using new materials of good quality. Tenant shall not commence the making
of any such modifications or alterations or the construction of any such
improvements until (i) all required governmental approvals and permits shall
have been obtained, (ii) all requirements regarding insurance imposed by this
Lease have been satisfied, (iii) Tenant shall have given Landlord at least five
business days prior written notice of its intention to commence such work so
that Landlord may post and file notices of non-responsibility, and (iv) if
requested by Landlord, Tenant shall have obtained contingent liability and broad
form builder's risk insurance in an amount reasonably satisfactory to Landlord
to cover any perils relating to the proposed work not covered by insurance
carried by Tenant pursuant to Article 9. In no event shall Tenant make any

modifications, alterations or improvements, once completed, shall not be altered
or removed from the Leased Premises during the Lease Term without Landlord's
written approval first obtained in accordance with the provisions of Article 6.1
above. At the expiration or sooner termination of this Lease, all such
modifications, alterations and improvements (other than Tenant's inventory,
equipment, moveable furniture, wall decorations and trade fixtures) shall
automatically become the property of Landlord and shall be surrendered to

                                      -9-
<PAGE>

Landlord as a part of the Leased Premises as required pursuant to Article 2,
unless Landlord shall require Tenant to remove any of such modifications,
alterations or improvements in accordance with the provisions of Article 2, in
which case Tenant shall so remove same. Landlord shall have no obligation to
reimburse to Tenant all or any portion of the cost or value of any such
modifications, alterations or improvements so surrendered to Landlord. All
modifications, alterations or improvements which are installed or constructed on
or attached to the Leased Premises by Landlord at Landlord's expense shall be
deemed real property and a part of the Leased Premises and shall be the property
of Landlord. All lighting, plumbing, electrical, heating, ventilating and air
conditioning fixtures, partitioning, window coverings, wall coverings and floor
coverings installed by Tenant shall be deemed improvements to the Leased
Premises and not trade fixtures of Tenant.

         6.3 ALTERATIONS: Tenant shall, at its sole cost make all modifications,
alterations and improvements to the Leased Premises that are required by an Law
because of (i) Tenant's use or occupancy of the Leased Premises, the Building,
the Outside Areas, or the Property, (ii) Tenant's application for any permit or
governmental approval, or (iii) Tenant's making of any modifications,
alterations or improvements to or within the Leased Premises. If Landlord shall,
at any time during the Lease Term, (i) be required by any governmental authority
to make any modifications, alterations or improvements to the Building or the
Project, the cost incurred by Landlord in making such modifications, alterations
or improvements, including an Landlord's interest rate per annum cost of money
factor shall be amortized by Landlord over the useful life of such
modifications, alterations or improvements, as determined in accordance with
generally accepted accounting standards, and the monthly amortized cost of such
modifications, alterations and improvements as so amortized shall be considered
a Property Maintenance Cost.

         6.4 LIENS: Tenant shall keep the Property and every part thereof free
from any liens and shall pay when due all bills arising out of any work
performed, materials furnished, or obligations incurred by Tenant, its agents
employees or contractors relating to the Property. If any such claim of lien is
recorded against Tenant's interest in this Lease, the Property or any part
thereof, Tenant shall bond against, discharge or otherwise cause such lien to be
entirely released within 30 days after the same has been so recorded. Tenant's
failure to do so shall be conclusively deemed a material default under the terms
of this Lease.

                                   ARTICLE 7:
                       ASSIGNMENT AND SUBLETTING BY TENANT

         7.1 BY TENANT: Tenant shall not sublet the Leased Premises (or any
portion thereof) or assign or encumber its interest in this Lease, whether
voluntarily or by operation of Law, without Landlord's prior written consent
which shall not be unreasonably withheld or delayed first obtained in accordance
with the provisions of this Article 7. Any attempted subletting, assignment or
encumbrance without Landlord's prior written consent, at Landlord's election,
shall constitute a default by Tenant under the terms of the Lease. The
acceptance of rent by Landlord from any person or entity other than Tenant, or
the acceptance of rent by Landlord from Tenant with knowledge of a violation of
the provisions of this Article, shall not be deemed to be a waiver by Landlord
of any provision of this Article or this Lease or to be a consent to any
subletting by Tenant or any assignment or encumbrance of Tenant's interest in
this Lease.

         7.2 MERGER OR REORGANIZATION:

         7.3 LANDLORD'S ELECTION: If Tenant shall desire to assign its interest
under this Lease or to sublet the Leased Premises, Tenant must first notify
Landlord, in writing, of its intent to so assign or sublet, at least 20 days in
advance of the date it intends to so assign its interest in this Lease or sublet
the Leased Premises but not sooner than one hundred eighty days in advance of
such date, specifying in detail the terms of such proposed assignment or
subletting, including the name of the proposed assignee or subleasee, the
proposed assignee's or subleasee's intended use of the Leased Premises, a
current financial statement of such proposed assignee or subleasee and the form
of documents to be used in effectuating such assignment or subletting. Landlord
shall have a period of 10 days following receipt of such notice within which to
do one of the following: (i) consent to such requested assignment or subletting
subject to Tenant's compliance with the conditions set forth in Article 7.4
below or (ii) refuse to so consent to such requested assignment or subletting,
provided that such consent shall not be unreasonably refused. It shall not be
unreasonable for Landlord to withhold its consent to any proposed assignment or
subletting if (i) the proposed assignee's or subtenant's anticipated use of the
Premises in-

                                     -10-
<PAGE>

volves the storage, use or disposal of a Hazardous Material other than Hazardous
Materials used by Tenant; (ii) if the proposed assignee or subtenant has been
required by any prior landlord, lender or governmental authority to clean up
Hazardous Materials unlawfully discharged by the proposed assignee or subtenant;
or (iii) if the proposed assignee or subtenant is subject to investigation or
enforcement order or proceeding by any governmental authority in connection with
the unlawful use, disposal or storage of a Hazardous Material. During said 10
day period, Tenant covenants and agrees to supply to Landlord, upon request, all
necessary or relevant information which Landlord may reasonably request
respecting such proposed assignment or subletting and/or the proposed assignee
or subleasee.

         7.4 CONDITIONS TO LANDLORD'S CONSENT: If Landlord elects to consent, or
shall have been ordered to so consent by a court of competent jurisdiction, to
such requested assignment, subletting or encumbrance, such consent shall be
expressly conditioned upon the occurrence of each of the conditions below set
forth, and any purported assignment, subletting or encumbrance made or ordered
prior to the full and complete satisfaction of each of the following conditions
shall be void and, at the election of Landlord, which election may be exercised
at any time following such a purported assignment, subletting or encumbrance but
prior to the satisfaction of each of the stated conditions, shall constitute a
material default by Tenant under this Lease until cured by satisfying in full
each such condition by the assignee, subleases or encumbrances. The conditions
are as follows:

         A. Landlord having approved in form and substance the assignment or
sublease agreement (or the encumbrance agreement), which approval shall not be
unreasonably withheld by Landlord if the requirements of this Article 7 are
otherwise complied with.

         B. Each such subleases or assignee having agreed, in writing
satisfactory to Landlord and its counsel and for the benefit of Landlord, to
assume, to be bound by, and to perform the obligations of this Lease to be
performed by Tenant (or, in the case of encumbrance, each such encumbrancer
having similarly agreed to assume, be bound by and to perform Tenant's
obligations upon a foreclosure or transfer in lieu thereof).

         C. Tenant having fully and completely performed all of its obligations
under the terms of this Lease as of the date of such assignment or subletting.

         D. Tenant having reimbursed to Landlord all reasonable costs and
attorneys' fees incurred by Landlord in conjunction with the processing and
documentation of any such requested subletting, assignment or encumbrance.

         E. Tenant having delivered to Landlord a complete and fully-executed
duplicate original of such sublease agreement, assignment agreement or
encumbrance (as applicable) and all related agreements.

         F. Tenant having paid, or having agreed in writing to pay as to future
payments, to Landlord 50 percent of all assignment consideration or excess
rentals to be paid to Tenant or to any other on Tenant's behalf or for Tenant's
benefit for such assignment or subletting as follows:

                  (1) If Tenant assigns its interest under this Lease and if all
or a portion of the consideration for such assignment is to be paid by the
assignee at the time of the assignment, that Tenant shall have paid to Landlord
and Landlord shall have received an amount equal to 50 percent of the assignment
consideration so paid or to be paid (whichever is the greater) at the time of
the assignment by the assignee; or

                  (2) If Tenant assigns its interest under this Lease and if
Tenant is to receive all or a portion of the consideration for such assignment
in future installments, that Tenant and Tenant's assignee shall have entered
into a written agreement with and for the benefit of Landlord satisfactory to
Landlord and its counsel whereby Tenant and Tenant's assignee jointly agree to
pay to Landlord an amount equal to 50 percent of all such future assignment
consideration installments to be paid by such assignee as and when such
assignment consideration is so paid.

                  (3) If Tenant subleases the Leased Premises, that Tenant and
Tenant's subleasee shall have entered into a written agreement with and for the
benefit of Landlord satisfactory to Landlord and its counsel whereby Tenant and
Tenant's subleasee jointly agree to pay to Landlord 50 percent of all excess
rentals to be paid by such subleases as and when such excess rentals are so
paid.

         7.5 ASSIGNMENT CONSIDERATION AND EXCESS RENTALS DEFINED: For purposes
of the Article, the term "assignment consideration" shall mean all consideration
to be paid by the assignee to Tenant or to any other on Tenant's behalf or for
Tenant's benefit as consideration for such assignment, less any commissions paid
by Tenant to a licensed real estate broker for arranging such assignment (not to
exceed then standard rates), and the term "excess rentals" shall mean all
consideration to be paid by the subleases to Tenant or to any other on Tenant's
behalf or for Tenant's benefit for the sublease of the Leased Premises in excess
of the rent due to Landlord under the terms of this Lease for the same period,
less any commissions paid by Tenant to a licensed real estate broker for
arranging such sublease (not to exceed then standard rates) and the cost of
improvements made to the subleased premises by Tenant at its expense for the
purpose of subleasing. Tenant agrees that the portion of any assignment
consideration and/or excess rentals arising from any assignment or subletting by
Tenant which is to be paid to Landlord pursuant to this Article now is and shall
then be the property of Landlord and not the property of Tenant.

         7.6 PAYMENTS: All payments required by this Article to be made to
Landlord shall be made in cash in full as and when they become due. At the time
Tenant, Tenant's assignment or subleases makes each such payment to Landlord,
Tenant or Tenant's assignee or subleases, as the case may be, shall deliver to
Landlord an itemized statement in reasonable detail showing the method by which
the amount due Landlord was calculated and certified by the party making such
payment as true and correct.

         7.7 GOOD FAITH: The rights granted to Tenant by this Article are
granted in consideration of Tenant's express covenant that all pertinent
allocations which are made by Tenant between the rental value of the Leased
Premises and the value of any of Tenant's personal property which may be
conveyed or leased generally concurrently with and which may reasonably be
considered a part of the same transaction as the permitted assignment or
subletting shall be made fairly, honestly and in good faith.

                                     -11-
<PAGE>

         7.8 EFFECT OF LANDLORD'S CONSENT: No subletting, assignment or
encumbrance, even with the consent of Landlord, shall relieve Tenant of its
personal and primary obligation to pay rent and to perform all of the
obligations to be performed by Tenant hereunder. Consent by Landlord to one or
more assignments or encumbrances of Tenant's interest in this Lease or to one or
more sublettings of the Leased Premises shall not be deemed to be a consent to
any subsequent assignment, encumbrance or subletting. If Landlord shall have
been ordered by a court of competent jurisdiction to consent to a requested
assignment or subletting, or such an assignment or subletting shall have been
ordered over the objection of Landlord, such assignment or subletting shall not
be binding between the assignee (or subleases) and Landlord until such time as
all conditions set forth in Article 7.4 above have been fully satisfied (to the
extent not then satisfied) by the assignee or sub subleases, including, without
limitation, the payment to Landlord of all agreed assignment considerations
and/or excess rentals then due Landlord.

This indemnity agreement shall survive until the latter to occur of (i) the date
of the expiration, or sooner termination, of this Lease, or (ii) the date Tenant
actually vacates the Leased Premises.

covered by insurance required to be carried by the party sustaining such loss
under the terms of this Lease, or is covered by insurance actually carried and
in force at the time of the loss, by the party sustaining such loss; provided,
however, that such waiver shall be effective only to the extent permitted by the
insurance covering such loss and to the extent such insurance is not prejudiced
thereby.

the Lease Commencement Date. Landlord's obligation to restore shall be limited
to the improvements constructed by Landlord. Landlord shall have no obligation
to restore any improvements made by Tenant to the Leased Premises or any of the
Tenant's personal property, inventory or trade fixtures.

         10.2 INSURANCE PROCEEDS: All insurance proceeds available from the fire
and property damage insurance carried by Landlord shall be paid to and become

new tenant, or otherwise); (iii) reasonable broker's fees, advertising costs and
other expenses of reletting the Leased Premises; (iv) reasonable costs of
carrying and maintaining the Leased Premises which costs would have been billed
to Tenant as Additional Rent had Tenant not defaulted and which include but are

         12.3 LANDLORD'S DEFAULT AND TENANT'S REMEDIES: In the event Landlord
fails to perform any of its obligations under this Lease, Landlord shall
nevertheless not be in default under the terms of this Lease until such time as

such failure to perform its obligations, and then only after Landlord shall have
had a reasonable period of time following its receipt of such notice within
which to perform such obligations. In the event of Landlord's default as above
set forth, then, and only then, Tenant shall have the following remedies only:

         A.   Tenant may then proceed in equity or at law to compel Landlord to
perform its obligations and/or to recover damages proximately caused by such
failure to perform (except as and to the extent Tenant has waived its right to
damages as provided in this Lease).

         B.   Tenant, at its option, may then cure any default of Landlord at
Landlord's cost. If, pursuant to this Subarticle, Tenant reasonably pays any sum
to any third party or does any act that requires the payment of any sum to any
third part at any time by reason of Landlord's default, the sum paid by, Tenant
shall be immediately due from Landlord to Tenant at the time Tenant supplies
Landlord with an invoice therefor (provided such invoice sets forth and is
accompanied by a written statement of Tenant setting forth in reasonable detail
the amount paid, the party to whom it was paid, the date it was paid, and the
reasons giving rise to such payment), together with interest at twelve percent
per annum from the date of such invoice until Tenant is reimbursed by Landlord.
Tenant may not offset such sums against any installment of rent due Landlord
under the terms of this Lease.

         12.4 LIMITATION ON TENANT'S RECOURSE: If Landlord is a corporation,
trust, partnership, joint venture, unincorporated association, or other form of
business entity, Tenant agrees that (i) the obligations of Landlord under this
Lease shall not constitute personal obligations of the officers, directors,
trustees, partners, joint venturers, members, owners, stockholders, or other
principals of such business entity and (ii) Tenant shall have recourse only to
the assets of such business entity and proceeds from any disposition thereof for
the satisfaction of such obligations and not against the assets of such
officers, directors, trustees, partners, joint venturers, members, owners,
stockholders or principals (other than to the extent of their interest in the
assets owned by such business entity). Additionally, if Landlord is a
partnership, then Tenant covenants and agrees:

         A.   No partner of Landlord shall be sued or named as a party in any
suit or action brought by Tenant with result to any alleged breach of this Lease
(except to the extent necessary to secure jurisdiction over the partnership and
then only for that sole purpose);

         B.   No service of process shall be made against any partner of
Landlord except for the sole purpose of securing jurisdiction over the
partnership; or its assets or the proceeds from any disposition thereof and

         C.   No writ of execution will ever be levied against the assets of any
partner of Landlord other than to the extent of his interest in the assets of
the partnership. Tenant further agrees that each of the foregoing covenants and
agreements shall be enforceable by Landlord and by any partner of Landlord and
shall be applicable to any actual or alleged misrepresentation or nondisclosure
made respecting this Lease or the Leased Premises or any factual or alleged
failure, default or breach of any covenant or agreement either expressly or
implicitly contained in this Lease or imposed by statue or at common law.

         12.5 TENANT'S WAIVER: Landlord and Tenant agree that the provisions of
Article 12.3 above are intended to supersede and replace the provisions of
California Civil Code Sections 1932(1), 1941 and 1942, and accordingly, Tenant
hereby waives the provisions of California Civil Code Sections 1932(1), 1941 and
1942 and/or any similar or successor Law regarding Tenant's right to terminate
this Lease or to make repairs and deduct the expenses of such repairs from the
rent due under this Lease.

                                  ARTICLE 13:
                              GENERAL PROVISIONS

         13.1 TAXES ON TENANT'S PROPERTY: Tenant shall pay before delinquency
any and all taxes, assessments, license fees, use fees, permit fees and public
charges of whatever nature or description levied, assessed or imposed against
Tenant or Landlord by a governmental agency arising out of, caused by reason of
or based upon Tenant's estate in this Lease, Tenant's ownership of property,
improvements made by Tenant to the Leased Premises or the Outside Areas,
improvements made by Landlord for Tenant's use within the Leased Premises or the
Outside Areas, Tenant's use (or estimated use) of public facilities or services
or Tenant's consumption (or estimated consumption) of public utilities, energy,
water or other resources. 10 days following notice by Landlord, Tenant shall
furnish Landlord with satisfactory evidence of these payments. If any such
taxes, assessments, fees or public charges are levied against Landlord,
Landlord's property, the Building or the Property, or if the assessed value of
the Building or the Property is increased by the inclusion therein of a value
placed upon same, then Landlord, after giving written notice to Tenant, shall
have the right to pay such taxes, assessment, fee or public charge and bill
Tenant, as Additional Rent, the amount of such taxes, assessment, fee or public
charge so paid on Tenant's behalf. Tenant shall, within ten days from the date
it receives an invoice from Landlord setting forth the

                                      -17-
<PAGE>

amount of such taxes, assessment, fee or public charge so levied, pay to
Landlord, as Additional Rent, the amount set forth in said invoice. Failure by
Tenant to pay the amount so invoiced within said ten day period shall be
conclusively deemed a default by Tenant under this Lease. Tenant shall have the
right, and the Landlord's full cooperation to bring suit in any court of
competent jurisdiction to recover from the taxing authority the amount of any
such taxes, assessment, fee or public charge so paid.

         13.2 HOLDING OVER: This Lease shall terminate without further notice on
the Lease Effective Date (as set forth in Article 1). Any holding over by Tenant
after expiration of the Lease Terminate shall neither constitute a renewal nor
extension of this Lease nor give Tenant any rights in or to the Leased Premises
except as expressly provided in this Article. Any such holding over shall be
deemed an unlawful detainer of the Leased Premises unless Landlord has consented
to same. Any such holding over to which Landlord has consented shall be
construed to be a tenancy from month to month, on the same terms and conditions
herein specified insofar as applicable, except that the Base Monthly Rent shall
be increased to an amount equal to one hundred fifty percent of the Base Monthly
Rent payable during the last full month immediately preceding such holding over.

         13.3 SUBORDINATION TO MORTGAGES: This Lease is subject to and
subordinate to all underlying ground leases, mortgages and deeds of trust which
affect the Building or the Property and which are of public record as of the
Effective Date of this Lease, and to all renewals, modifications,
consolidations, replacements and extensions thereof. However, if the lessor
under any such ground lease or any lender holding any such mortgage or deed of
trust shall advise Landlord that it desires or requires this Lease to be made
prior and superior thereto, then, upon written request of Landlord to Tenant,
Tenant shall promptly execute,, acknowledge and deliver any and all documents or
instruments which Landlord and such lessor or lender deem necessary or desirable
to make this Lease prior thereto. Tenant hereby consents to Landlord's ground
leasing the land underlying the Building or the Property and/or encumbering the
Building or the Property as security for future loans on such terms as Landlord
shall desire, all of which future ground leases, mortgages or deeds of trust
shall be subject to and subordinate to this Lease. However, if any lessor under
any such future ground lease or any lender holding such future mortgage or deed
of trust shall desire or require that this Lease be made subject to and
subordinate to such future ground lease, mortgage or deed of trust, then Tenant
agrees, within ten days after Landlord's written request therefor, to execute,
acknowledge and deliver to Landlord any and all documents or instruments
requested by Landlord or by such lessor or lender as may be necessary or proper
to assure the subordination of this Lease to such future ground lease, mortgage
or deed of trust, but only if such lessor or lender agrees to recognize Tenant's
rights under this Lease and agrees not to disturb Tenant's quiet possession of
the Leased Premises so long as Tenant is not in default under this Lease.

         13.4 TENANT'S ATTORNMENT UPON FORECLOSURE: Tenant shall, upon request,
attorn (i) to any purchaser of the Building or the Property at any foreclosure
sale or private sale conducted pursuant to any security instrument encumbering
the Building or the Property, (ii) to any grantee or transferee designated in
any deed given in lieu of foreclosure of any security interest encumbering the
Building or the Property, or (iii) to the lessor under any underlying ground
lease of the land underlying the Building or the Property, should such ground
lease be terminated; provided that such purchaser, grantee or lessor recognizes
Tenant's rights under this Lease.

         13.5 MORTGAGEE PROTECTION: In the event of any default on the part of
Landlord, Tenant will give notice by registered mail to any Lender or lessor
under any underlying ground lease who shall have requested, in writing, to
Tenant that it be provided with such notice, and Tenant shall offer such Lender
or lessor a reasonable opportunity to cure the default, including time to obtain
possession of the Leased Premises by power of sale or judicial foreclosure or
other appropriate legal proceedings if reasonably necessary to effect a cure.

         13.6 ESTOPPEL CERTIFICATES: Tenant will, following any request by
Landlord, promptly execute and deliver to Landlord an estoppel certificate (i)
certifying that this Lease is unmodified and in full force and effect, or, if
modified, stating the nature of such modification and certifying that this
Lease, as so modified, is in full force and effect, (ii) stating the date to
which the rent and other charges are paid in advance, if any, (iii)
acknowledging that there are not, to Tenant's knowledge, any uncured defaults on
the part of Landlord hereunder, or specifying such defaults if any are claimed,
and (iv) certifying such other information about this Lease as may be reasonably
requested by Landlord, its Lender or prospective lenders, investor or purchaser
of the Building or the Property. Tenant's failure to execute and deliver such
estoppel certificate within ten days after Landlord's request therefor shall be
a material default by Tenant under this Lease, and Landlord shall have all of
the rights and remedies available to Landlord as Landlord would otherwise have
in the case of any other material default by Tenant, including the right to
terminate this Lease and sue for damages proximately caused thereby, it being
agreed and understood by Tenant that Tenant's failure to so deliver such
estoppel certificate in a timely manner could result in Landlord being unable to
perform committed obligations to other third parties which were made by Landlord
in reliance upon this covenant of Tenant. Landlord and Tenant intend that any
statement delivered pursuant to this Article may be relied upon by any Lender or
purchaser or prospective Lender or purchaser of the Building, the Property, or
any interest herein.

         13.7 TENANT'S FINANCIAL INFORMATION (PUBLIC): Tenant shall, within five
business days after Landlord's request therefor deliver to Landlord a copy of a
current (public) financial statement (if Tenant is a public company) including
an income statement for the most recent twelve month period and a balance sheet
and any such other information reasonably requested by Landlord regarding
Tenant's financial condition. Tenant acknowledges that Landlord is relying upon
the financial information provided to Landlord by Tenant prior to entering into
this lease and the information to be provided to Landlord by Tenant during the
terminate of this Lease. Landlord shall be entitled to disclose such financial
statements or other information to its Lender, to any present or prospective
principal of or investor in Landlord, or to any prospective Lender or purchaser
of the Building, the Property or any portion thereof or interest therein. Any
such financial statement or other information which is marked "confidential" or
company secrets" (or is otherwise similarly marked by Tenant) shall be
confidential and shall not be disclosed by Landlord to any third party except as
specifically provided in this Article, unless the same becomes a part of the
public domain without the fault of Landlord.

         13.8 TRANSFER BY LANDLORD: Landlord and its successors in interest
shall have the right to transfer their interest in the Building, the Property,
or any portion thereof at any time and to any person or entity. In the event of
any such transfer, provided that the transferee recognizes all rights of Tenant
and assumes all obligations of Landlord under the Lease, the Landlord originally
named herein (and in the case of any subsequent transfer, the transferor), from
the date of such transfer, (i) shall be automatically relieved, without any
further act by any person or entity, of all liability for the performance of the
obligations of the Landlord hereunder which may accrue after the

                                      -18-
<PAGE>

date of such transfer and (ii) shall be relieved of all liability for the
performance of the obligations of the Landlord hereunder which have accrued
before the date of transfer if its transferee agrees to assume and perform all
such prior obligations of the Landlord hereunder, Tenant shall attorn to any
such transferee. After the date of any such transfer, the terminate "Landlord"

covered under any insurance policy carried by Landlord in connection with the
Building and/or Property; (e) damage and repairs necessitated by the negligence
or willful misconduct of Landlord or Landlord's employees, contractors or
agents; (f) executive salaries or salaries of service personnel to the extent
that such service personnel perform services other than in connection with the

Landlord shall keep at its office for a period of at least twelve (12) months
after the expiration of each calendar year, full and accurate books, records and

agent shall have the right at all reasonable times within said twelve (12) month
period to inspect such books, records and supporting documents, to challenge the
accuracy of any Property Maintenance Costs and to procure an audit. In the event
an audit of the records results in a determination that the Property Maintenance
Costs charged to Tenant were in excess of 5% more than the actual Property
Maintenance Costs, Landlord shall pay for the reasonable cost of such audit.

Section 14.5

Landlord's Interest Rate: Throughout the Lease where Tenant is obligated to pay
interest to Landlord, Tenant shall so pay interest at an annual interest rate
equal to the Wells Fargo National Bank Prime Lending Interest Rate, as
determined from time to time by Wells Fargo National Bank, plus three percent
(3%). In the event that such interest rate is not available, Landlord in its
reasonable opinion shall select another major regional national bank which
publishes a prime lending rate of interest to use as a reference rate to which
three percent (3%) shall be added.

Section 15

Additional Improvements: Landlord, or an affiliate of Landlord, shall install
interior improvements in accordance with a plan to be approved by Landlord and
Tenant. Landlord shall use its best efforts to complete construction of the
interior improvements prior to February 1, 1995. In the event that the
improvements are not complete by that date, Tenant shall accept the Premises on
February 1, 1995, on which date the Lease Term shall commence. Base Monthly Rent
for February shall be prorated based on the actual date of completion of
construction of interior improvements, provided, however, that Tenant shall pay
not less than:

     for Base Monthly Rent for the month of February, and full base Monthly Rent
for March 1995, and succeeding months.

Landlord shall pay the cost of construction of interior improvements in an
amount equal to fifty three thousand seven hundred thirteen dollars
($53,713.00). In addition, Tenant may require Landlord to increase its
contribution for the cost of construction of interior improvements by an amount
up to an additional fifty three thousand seven hundred thirteen dollars
($53,713.00) in which case the Base Monthly Rent shall increase by an amount
equal to one the thirty three one hundreds percent (1.33%)
<PAGE>

times the actual amount of the additional allowance provided by Landlord. Tenant
shall pay the cost of construction (if any) in excess of the amounts which
Landlord has agreed to provide.

Section 16

Option to Renew: Landlord hereby grants to Tenant the option to renew the Lease,
for an additional term of five (5) years (the "Renewal Term") with the option
commencing on the expiration of the Lease (the "First Renewal Commencement
Date") and ending five (5) years thereafter (the "First Renewal Expiration
Date").

1.   The lease of the Leased Premises for either of the Renewal Terms shall be
on the same terms and conditions as set forth in the Lease, except:

     A.  That the rental for the Leased Premises during the Renewal Term shall
be as set forth below in Paragraph 3, and

     B.  That the Security Deposit shall be increased to the rental amount
determined in Paragraph 3 {the "increased Security Deposit Amount").

2.   Tenant shall notify Landlord of Tenant's exercise of its right to renew the
Lease for the Renewal Term only by giving to Landlord written notice not sooner
than nine (9) months prior to the Renewal Commencement Date and not later than
six (6) months prior to the Renewal Commencement Date (time is expressly of the
essence to Landlord). Any attempted exercise of this Option made other than
within the time period stated or in the manner stated shall be void and of no
force or effect. In the event that Tenant does not or is not entitled to
exercise its option Tenant shall have no further rights hereunder.

3.   If Tenant shall have properly and timely exercised its right to extend the
term of the Lease, the term of tl3e Lease shall be so extended for the Renewal
Term on the same terms and conditions contained in the Lease; provided, however,
the Base Monthly Rent for each month of the first thirty (30) months of the
Renewal Term shall be calculated as follows: The new Base Monthly Rent for the
Renewal Term shall be the greater of: (i) the Base Monthly Rent being paid by
Tenant to Landlord during the final full month of the final year of the initial
Lease Term, or (ii) the Then Market Rental Rate for the Lease Premises.

4.   The term "Then Monthly Market Rental Rate" shall be determined by mutual
agreement between Landlord and Tenant or, in the event such agreement cannot be
made within ten (10) days from the date Tenant shall have exercised this option,
Landlord and Tenant shall each appoint a real estate appraiser with at least
five (5) years full-time commercial/industrial appraisal experience in Santa
Clara County to appraise and determine the fair market monthly rental rate the
Leased Premises, in their then existing condition for the use specified in the
Lease could be leased for, on the same terms and conditions set forth in the
Lease, to a qualified tenant ready, willing and able to lease the Leased
Premises for a term equal to the Renewal Term. If either party does not appoint
an appraiser within ten (10) days after the other party has given notice of the
name of its appraiser, the other party can then apply to the President of the
Santa Clara County Real Estate Board or the presiding Judge of the Superior
Court of that County for the selection of a second appraiser who meets the
qualifications stated above. The failing party shall bear the cost of appointing
the second appraiser and of paying the second appraiser's fee. The two
appraisers shall attempt to establish the Then Monthly Market Rental Rate for
the Leased Premises. If the two appraisers are unable to agree on the Then
Monthly Market Rental Rate for the Leased Premises within ten (10) days after
the second appraiser has been selected or appointed, then the two appraisers
shall attempt to select a third appraiser meeting the qualifications stated
above. If they fail to agree on a third appraiser, either party can follow the
above procedure for having an appraiser appointed by the Real Estate Board or a
judiciary. Each of the parties shall bear one-half (1/2) of the cost of
appointing the third appraiser and of paying the third appraiser's fee. Unless
the three appraisers are able to agree on the Then Monthly Market Rental Rate
for the Leased Premises within ten (10) days after the selection or appointment
of the third appraiser,
<PAGE>

First Addendum To Lease
Page 7

the two appraisal amounts being calculated most closely together, after having
discarded the appraisal amount which most greatly varies from the other two
appraisal amounts, shall be added together then divided by two (2). The
resulting rental amount shall be defined as the. Then Monthly Market Rental Rate
for the Leased Premises. In no event, however, shall the resulting Then Monthly
Market Rental Rate for the Renewal Term be less than the Base Monthly Rent paid
during the final full month of the initial Lease Term.

     The Base Monthly Rent shall be adjusted at the end of the thirtieth (30th)
month of the Renewal Term by multiplying the Base Monthly Rent for the thirtieth
(30th) month times a fraction the numerator of which shall be the Consumer Price
Index published immediately prior to the period including the thirtieth (30th)
month of the Renewal Term and the denominator of which shall be the Consumer
Price Index published immediately prior to the first (1st) month of the Renewal
Term. In no event, however, shall the Base Monthly Rent for the last thirty (30)
months of either Renewal Term be less than the Base Monthly Rent for the first
thirty (30) months of the Renewal Term.

For purposes of this option, the term "Consumer Price Index" shall mean the
Consumer Price Index, All Urban Consumers, Subgroup "All Items", for the San
Francisco-Oakland-San Jose Area (1982-1984=100), now being published by the
United States Department of Labor, Bureau of Labor Statistics. If the Consumer
Price Index is changed so that the base year is altered from that used as of the
Lease Commencement Date, then the Consumer Price Index shall be converted in
accordance with the conversion factor published by the United States Department
of Labor, Bureau of Labor Statistics, to obtain the same result that would have
been obtained had the base year not been changed. If no conversion factor is
available, or if the Consumer Price Index is otherwise changed, revised or
discontinued for any reason, there shall be substituted in lieu thereof and the
term "Consumer Price Index" shall thereafter refer to the most nearly comparable
official price index of the United States Government reasonably designated by
Landlord in order to obtain substantially the same result for any adjustment
required by this Option as would have been obtained had the original Consumer
Price Index not been changed, revised or discontinued.

IN WITNESS WHEREOF, Landlord and Tenant have executed this First Addendum To
Lease with the intent to be legally bound thereby, to be effective as of the
date the second party signs this First Addendum To Lease.
