                                      LEASE

      This Lease is made and entered into as of June 1, 1995, by and between
Ferrari Brothers, a California general partnership ("Landlord"), whose address
is 1265 Montecito Avenue, Suite 200, Mountain View, California 94043, and Analog
Devices, Inc., a Massachusetts corporation ("Tenant"), whose address is 3
Technology Way, Norwood, Massachusetts 02062-9106, Attn: Mr. William Wise.


      Landlord and Tenant agree to the terms, covenants and conditions of this
Lease, as follows:

      1.    PREMISES. Landlord hereby leases to Tenant and Tenant hereby leases
from Landlord for the term, at the rental, and upon all of the other terms,
covenants and conditions set forth herein, those certain premises (the
"Premises") as shown on EXHIBIT "A" attached hereto consisting of approximately
27,379 square feet of space within that certain building (the "Building")
situated in the City of Sunnyvale, County of Santa Clara, State of California,
commonly known as 610 Weddell Drive and more particularly described in EXHIBIT
"B" attached hereto. Tenant is entering into this Lease in conjunction with its
acquisition of certain fabrication facility assets situated on the Premises from
Performance Semiconductor Corporation ("PSC"), the prior tenant of the Premises.

Tenant shall also have the exclusive right to use the loading docks (if any)
contiguous to the Premises and located within the Outside Areas, and the
nonexclusive right to use all other portions of the Outside Areas in common with
other tenants from time to time occupying space within the Building together
with their respective agents, contractors, and other invitees. Landlord reserves
the right to grant such easements burdening the Outside Areas as Landlord in its
reasonable discretion deems appropriate provided the same do not unreasonably
interfere with Tenant's ability to use the Outside Areas. Tenant at it sole
expense shall maintain the water monitoring wells located within the Outside
Areas as shown on EXHIBIT "B."

      The parcel of land on which the Building is situated, together with the
Building and all other improvements now or hereafter located thereon, is
hereafter called the "Project."

      The portion of the parcel of land described above not covered by the
Building is hereafter called the "Outside Areas."


                                        1

      "Tenant's Share" as used in this Lease means that percentage of the total
number of square feet of leasable space in the Building which is contained in
the Premises, which the parties agree is Forty-Three and Four Tenths percent
(43.4%).

      2.    TERM. The term of this Lease shall commence on June 16, 1995 (the
"Commencement Date"), and end on March 31, 2000 (the "Expiration Date"), unless
sooner terminated pursuant to the provisions hereof.

      3.    Rent.

            3.1   INITIAL BASE RENT. Commencing on the Commencement Date, Tenant
shall pay to Landlord for each calendar month of the term of this Lease, monthly
base rent (hereafter called "Base Rent"), in the amount of Thirty Five Thousand
Dollars ($35,000). Base Rent shall be subject to adjustment from time to time as
set forth in Paragraph 3.2.

            3.2   RENTAL ADJUSTMENT. The monthly Base Rent payable hereunder
shall be adjusted as of April 1, 1996 and as of April 1 of each successive year
(each such date herein called a "Rental Adjustment Date") during the term of
this Lease to reflect any changes in the cost of living. The adjustment or
adjustments, if any, shall be calculated upon the basis of the United States
Department of Labor, Bureau of Labor Statistics CONSUMER PRICE INDEX FOR ALL
URBAN CONSUMERS, FOR SAN FRANCISCO-OAKLAND-SAN JOSE (1982-84=100), hereafter
referred to as the "Index". The Index for said subgroup most recently published
as of April 1, 1995 shall be considered the "base". On the first Rental
Adjustment Date, the monthly Base Rent shall be adjusted by the percentage
increase, if any, in the Index as of the Rental Adjustment Date, over the base.
On each subsequent Rental Adjustment Date, the monthly Base Rent (as previously
adjusted) shall be further adjusted by the percentage increase, if any, in the
Index as of the Rental Adjustment Date over the Index as of the preceding Rental
Adjustment Date. When the Base Rent is determined upon the Rental Adjustment
Date, Landlord shall give Tenant written notice to that effect indicating how
the new Base Rent figure was computed in accordance with this paragraph. If the
Index does not exist on any Rental Adjustment Date in the same format as
referred to in this paragraph, Landlord shall substitute in lieu thereof an
index reasonably comparable to the Index referred to above which is then
published by the Bureau of Labor Statistics, or by a successor or similar
governmental agency, or, if no governmental agency then publishes an index,
Landlord shall substitute therefor any commonly accepted index designed to
reflect changes in the cost of living which is published by a reputable private
organization.


                                        2

            3.3   MANNER OF PAYMENT. Tenant shall pay to Landlord the rent
calculated as set forth above without deduction, offset, or abatement (except as
expressly otherwise provided in Paragraphs 15.5, 16.1, and 16.5 below), and
without prior notice or demand, in advance on the first day of each calendar
month of the term of this Lease. Rent shall be payable in lawful money of the
United States to Landlord at 1265 Montecito Avenue, Suite 200, Mountain View,
California 94043 or at such other place as Landlord may from time to time
designate in writing. Tenant's obligation to pay rent for any partial month
shall be prorated on the basis of a thirty (30) day month.

            3.4   LATE PAYMENT CHARGE. If any installment of rent or any other
sum due from Tenant is not received by Landlord within ten (10) days after the
due date, Tenant shall pay to Landlord an additional sum of Seven Hundred
Dollars ($700.00). Such sum shall represent liquidated damages for, and a
reasonable estimate of, Landlord's administrative costs of collection, the exact
amount of which would be extremely difficult or impractical to fix. Landlord's
acceptance of such late charge shall not excuse any default by Tenant hereunder,
and shall not preclude Landlord from pursuing any other rights and remedies it
may have relating to such default.

      4.    SECURITY DEPOSIT. Prior to the Commencement Date, Tenant shall
establish a Certificate of Deposit in the name of Analog Devices, Inc. in favor
of Ferrari Brothers, a California general partnership, in the sum of Nineteen
Thousand Three Hundred Sixty Two Dollars and Twenty Two Cents ($19,362.22). It
is specifically agreed that Landlord shall have access to the funds represented
by the Certificate of Deposit only for the purposes and under the conditions set
forth herein. The Certificate of Deposit shall be renewable on an annual basis
and shall be renewed by Tenant at least thirty (30) days prior to the scheduled
maturity thereof each year. The Certificate of Deposit, as the same may be
renewed from time-to-time, shall remain in effect at least until the sooner of
the expiration of this Lease or thirty (30) days after the sooner termination
thereof, and in all events at least until ten (10) days after Tenant has vacated
the Premises. If Tenant fails to pay rent or any other sum due hereunder, or
otherwise defaults with respect to any provision of this Lease, Landlord may
draw sums from the Certificate of Deposit for the payment of any rent or other
sum in default, or to compensate Landlord for the payment of any other sum,
including attorneys' fees, which Landlord spends by reason of Tenant's default.
Landlord may draw upon the Certificate of Deposit without prejudice to any other
remedy Landlord may have by reason of Tenant's default or breach. If Landlord so
draws all or a portion of the Certificate of Deposit, Tenant shall, within
twenty (20) days after demand in writing therefor, restore the amount of the
Certificate of Deposit to the original amount thereof.


                                        3

      5.    Taxes.

            5.1   TENANT'S PERSONAL PROPERTY. Tenant shall pay directly to the
charging authority prior to delinquency all taxes assessed against and levied
upon Tenant's leasehold improvements, trade fixtures, furnishings, equipment and
all other personal property and merchandise of Tenant situated in or about the
Premises.

            5.2   REAL PROPERTY TAXES. Tenant's Share of all Real Property Taxes
(as hereafter defined) levied with respect to the Project shall be deemed
Operating Expenses as described in Paragraph 9 below.

                  The term "Real Property Taxes" as used herein shall mean (i)
all taxes, assessments, levies, and other charges of any kind or nature
whatsoever, general and special (including all installments of principal and
interest required to pay for any general or special assessments for public
improvements, services, or benefits and any increases resulting from
reassessments caused by any change in ownership, new construction, or change in
valuation), now or hereafter imposed by any governmental or quasi-governmental
authority or special district having the direct or indirect power to tax or levy
assessments, which are levied or assessed against or with respect to (a) the
value, occupancy or use of the Project (as now constructed or as may at any time
hereinafter be constructed, altered, or otherwise changed), (b) the fixtures,
equipment, and other real or personal property of Landlord that are an integral
part of the Project, (c) the gross receipts, income, and rentals from the
Project, or (d) the use of the Outside Areas, public utilities, or energy within
the Project; (ii) all charges, levies or fees imposed by reason of environmental
regulation or other governmental control of the Project; (iii) all new exercise,
transaction, sales, privilege or other taxes now or hereafter imposed upon
Landlord as a result of this Lease; and (iv) all reasonable costs and fees
(including attorneys' fees) incurred by Landlord in contesting any Real Property
Taxes pertaining to the Project and in negotiating with public authorities as to
any Real Property Taxes pertaining to the Project. If at any time during the
lease term the taxation or assessment of the Project prevailing as of the
Commencement Date shall be altered so that in lieu of or in addition to any Real
Property Taxes described above there shall be levied, assessed or imposed
(whether by reason of a change in the method of taxation or assessment, creation
of a new tax or charge, or any other cause) an alternate, substitute, or
additional tax or charge (i) on the value, use or occupancy of the Project, (ii)
on or measured by the gross receipts, income, or rentals from the Project, or on
Landlord's business of leasing the Project, or (iii) computed in any manner with
respect to the operation of the Project, then any such tax or charge, however
designated, shall be included within the meaning of the term "Real Property
Taxes" for purposes of the Lease. If any Real Property Tax

                                        4

is based upon property or rents unrelated to the Project, then only that part of
such Real Property Tax that is fairly allocable to the Project shall be included
within the meaning of the term "Real Property Taxes." Notwithstanding the
foregoing, the term "Real Property Taxes" shall not include estate, inheritance,
transfer, gift or franchise taxes of Landlord or the federal or state net income
tax imposed on Landlord's income from all sources.

                  Notwithstanding the foregoing, Tenant shall have no obligation
to pay any increase in Real Property Taxes due to a reassessment of the value of
the Premises under Article XIIIA of the California Constitution to the extent
such reassessment results from new construction on land adjacent to the Premises
owned by Landlord and included within the tax parcel of which the Premises are a
part. Nothing in this paragraph shall be construed to relieve Tenant of the
obligation of paying its share of increases in taxes under said Article XIIIA or
any other provision of law in accordance with the provisions of this Lease,
except as specifically set forth above in this paragraph.

                  Real Property Taxes shall be prorated on the basis of a
365-day year to account for any fractional portion of a fiscal tax year included
in the Lease term at the commencement or expiration of the term.

                  If any general or special assessment is levied and assessed
against the Premises, Landlord may elect either to pay the assessment in full or
to allow the assessment to go to bond. If Landlord pays the assessment in full,
Operating Expenses shall include a sum equal to that which would have been
payable (as both principal and interest) had Landlord allowed the assessment to
go to bond.

                  Tenant shall have the right, upon written request to Landlord,
to inspect each and every original tax bill relating to taxes assessed during
the Lease term against the Premises or the tax parcel of which the Premises are
a part. Landlord shall make such original tax bill available for Tenant's
inspection at Landlord's headquarters or at such other reasonable place as
Landlord may determine, during reasonable business hours.

                  Tenant at its cost shall have the right, at any time, to
contest any Real Property Taxes that are to be paid by Tenant, provided that
Tenant shall first pay any Real Property Taxes it desires to contest. Landlord
shall not be required to join in any contest brought by Tenant unless the
provisions of any law require that the contest be brought by or in the name of
Landlord or any owner of the Premises. In that case Landlord shall join in the
contest or permit it to be brought in Landlord's


                                        5

name as long as Landlord is not required to bear any cost. Tenant, on final
determination of the contest, shall immediately pay or discharge any decision or
judgement rendered, together with all costs, charges, interest, and penalties
incidental to the decision or judgement.

                  Notwithstanding anything to the contrary, Tenant shall only be
required to pay charges by the Environmental Protection Agency or other
governmental agencies relating to cleaning up contamination on, under, or about
the Premises to the extent such contamination results from Tenant's use of the
Premises or is caused by Tenant to exist in, on, or about the Premises, and such
expense shall be limited to costs incurred to perform such investigations and
clean-up as may be required by law. It is expressly understood that, except as
otherwise provided in Paragraph 7 below, Tenant shall have no liability in
connection with any contamination of the Premises occurring before Tenant's
entry into the Premises, or occurring after expiration or sooner termination of
the Lease term and Tenant's vacating of the Premises, except to the extent
Tenant causes such contamination.

      6.    Use.

            6.1   PERMITTED USES. The Premises shall be used and occupied only
for the following purposes: office, research, development, manufacturing and
sale of electronic components, and for no other use or purpose without first
obtaining Landlord's written consent which shall not be unreasonably withheld.

            6.2   COMPLIANCE WITH LAW. Tenant shall at its sole expense at all
times during the Lease term comply with all laws, statutes, ordinances,
regulations, codes or other rules and regulations of lawful governmental
authority (collectively "Regulations") relating to the Premises. Notwithstanding
anything to the contrary in this Lease, Landlord shall perform and pay for all
modifications to the structure of the Building (i.e., the exterior walls, roof
structure and building foundation), required in order to comply with any such
Regulations, unless the need for compliance is (a) caused by Tenant's particular
use of the Premises (rather than merely being a requirement for all buildings
within the jurisdiction of such governmental authority), or (b) caused by any
new construction performed by or on behalf of Tenant in, on or about the
Premises (except to the extent that during the process of such new construction
violations of codes in effect at the time Landlord constructed the Building are
found, in which case Landlord shall be solely liable for the cost of curing such
violations). Tenant shall perform and pay for any and all improvements or other
modifications required to be made with respect to any improvements made to the
Premises by Tenant, and all other portions of the Premises except as provided in
the


                                        6

second sentence of this paragraph. Without limiting the generality of the
foregoing, Tenant specifically shall perform and pay at its sole cost for any
and all work required to bring the Premises into compliance with the Americans
with Disabilities Act and the Toxic Gas Ordinance.

      7.    Hazardous Materials.

            As used herein, "Hazardous Materials" means any hazardous, toxic,
environmentally damaging or radioactive materials, substances or wastes,
including, but not limited to, those materials, substances or wastes: (1)
defined or listed as hazardous or extremely hazardous materials or wastes
pursuant to Title 22, Division 4, Chapter 30, of the California Code of
Regulations, as may be amended; (2) defined or listed as hazardous substances
pursuant to the Comprehensive Environmental Response, Compensation and Liability
Act, 42 U.S.C. _ 9601, et seq., as may be amended; (3) defined or listed as
hazardous or acutely hazardous wastes pursuant to the Resource Conservation and
Recovery Act, 42 U.S.C. _ 6901, et seq., as may be amended; and/or (4) which
consist in whole or part of petroleum, petroleum fractions, petroleum products
or petroleum distillates.

            Tenant shall not cause or permit to be discharged from or about the
Premises, the Building, or the Project any Hazardous Materials. Without limiting
the foregoing, Tenant shall not cause or permit to be discharged any Hazardous
Materials into the groundwater or soils underlying or adjacent to the Premises,
Building or Project. Prior to its occupancy of the Premises Tenant shall provide
Landlord with a copy of the following items relating to Tenant's bringing,
using, or storing any Hazardous Materials on the Premises: (i) a copy of
Tenant's Material Safety Data Sheet in the same form submitted to OSHA, (ii) a
written detailed description of where on the Premises Tenant intends to store
Hazardous Materials and the manner (volume and type of containers for each
Hazardous Material, and method of securing the same against movement) in which
such Hazardous Materials will be stored, and (iii) a general description of the
processes for which the Hazardous Materials will be used. Tenant shall deliver
to Landlord in writing a detailed description of any updates to or other
modifications of the foregoing as and when they occur.

            Tenant, at its sole expense shall comply with all applicable
governmental rules, regulations, codes, ordinances, statutes, directives and
other requirements (collectively, "Laws") respecting Hazardous Materials in
connection with Tenant's activities and the activities of its agents, employees,
contractors and invitees on or about the Premises, the Building or the Project.
Tenant, at its sole cost, shall perform all investigations, clean-up and other
response actions which may be required by any


                                        7

governmental authority in, on, or about the Project, to the extent the same
relate to Hazardous Materials the existence of which in, on or about the Project
was caused by Tenant or its agents, contractors, employees, or invitees. For
purposes of this Paragraph 7 and all other provisions of this Lease, any
Hazardous Materials existing in, on or about the Project which are of the same
type, or which are derivative combinations or products thereof, of any Hazardous
Materials or other chemicals or substances which have at any time been used,
stored, generated, or released in, at, about or from the Premises shall be
deemed to have been released and caused to exist in, on or about the Project by
Tenant unless Tenant demonstrates by a preponderance of the evidence that the
existence of such Hazardous Materials was not caused by Tenant. For purposes of
this Paragraph 7, Hazardous Materials located in, on or about the Premises,
Building, or Project shall include without limitation Hazardous Materials
situated in the groundwater or soil.

            Tenant shall indemnify, protect, defend and hold harmless Landlord
from and against all costs (including, but not limited to, environmental
response costs and Landlord's attorneys' and experts' fees and costs), expenses,
claims, judgments, losses, demands, liabilities, causes of action, governmental
directives, proceedings or hearings, relating to the use, handling, generation,
storage, transportation, release or disposal of Hazardous Materials by Tenant,
or its employees, agents, invitees or contractors on, in, beneath, about or
from, the Premises, the Building or the Project, and/or relating to the breach
of any of Tenant's obligations under this Paragraph 7. Tenant's obligation to
defend shall mean with legal counsel approved by Landlord, which approval shall
not unreasonably be withheld or delayed. Without limitation of the foregoing, in
the event Tenant, its employees, agents, invitees or contractors, causes or has
caused the presence of Hazardous Materials in, on, or about the Premises, or in
the groundwater or land underlying the Premises or the Building, or, in, on, or
about any groundwater or land adjacent to, on, in the vicinity of the Premises,
Tenant shall indemnify, protect, defend, and hold harmless Landlord from and
against the cost of environmental consultants, attorneys, and other consultants
as Landlord determines are appropriate to assist Landlord in (1) investigating
the source, extent, and composition of such Hazardous Materials, (2) cleaning up
or otherwise remediating the same, (3) dealing with any potential or actual
liability of Landlord and/or Tenant respecting such Hazardous Materials, and (4)
otherwise dealing with such Hazardous Materials. Tenant shall reimburse Landlord
for (i) losses in or reductions to rental income resulting from Tenant's use,
handling, generation, storage, transportation, release or disposal of Hazardous
Materials; (ii) all costs of clean-up or other alterations to the Premises, the
Building or the Project necessitated by Tenant's use, handling, generation,
storage, transportation, release or disposal of Hazardous Materials; and (iii)
any diminution in the fair market value of the Project caused by


                                        8

Tenant's use, handling, generation, storage, transportation, release or disposal
of Hazardous Materials.

            Tenant shall notify Landlord in writing, immediately upon becoming
aware of: (1) any environmental investigation, clean-up or other environmental
response action requested, demanded, instituted or to be instituted by any
person, including but not limited to a governmental entity, relating to any
release or migration of Hazardous Materials on, in, beneath, to or adjacent to
the Premises, the Building or the Project; (2) any environmental investigation,
cleanup or other environmental response action requested, demanded, instituted
or to be instituted by any person, including a governmental entity, relating to
the use, handling, generation, storage, transportation, release or disposal of
Hazardous Materials by Tenant, its employees, agents, invitees or contractors
on, in, beneath, about or from the Premises, the Building or the Project; (3)
any claim or demand made or threatened by any person, including but not limited
to a governmental entity, against the Landlord or Tenant, the Premises, the
Building or the Project relating to damages, contribution, cost recovery,
compensation, loss or injury relating to or claimed to result from any Hazardous
Materials that have come to be located on or about the Premises, the Building or
the Project; or (4) any data, workplans, proposals or reports submitted to any
governmental entity arising out of or in connection with any Hazardous Materials
on or about the Premises, the Building or the Project, including but not limited
to any complaints, notices, warnings or asserted violations in connection
therewith.

            Landlord shall have the right, but not the obligation, in its sole
discretion, to conduct any inspections of the Premises, the Building and the
Project regarding Hazardous Materials on, in, beneath or about same. Landlord
shall give Tenant forty-eight (48) hours advance notice of any such inspection,
except in the event of an emergency situation. When conducting any such
inspections, Landlord shall avoid unreasonably disrupting Tenant's activities.
Tenant shall provide Landlord with reasonable cooperation to facilitate any such
inspection by Landlord, its agents or representatives.

            Under no circumstances shall Tenant install, temporarily or
permanently, any underground or below-floor tanks relating to the use, storage
or disposal of Hazardous Materials.

            Prior to the expiration or termination of this Lease, Tenant shall
decontaminate, remove or clean any equipment, improvements or facilities used by
Tenant at the Premises, Building or Project in connection with Hazardous
Materials, in full compliance with applicable Laws.


                                        9

            To the extent any of the provisions of this Lease conflict with the
provisions of Paragraph 7, the provisions of Paragraph 7 shall be controlling.
The obligations of Tenant under this Paragraph 7 shall survive the expiration of
the Lease term.

      8.    RESTRICTIONS ON USE. Tenant shall not use or permit the use of the
Premises in any manner that will tend to create waste on the Premises or
constitute a nuisance to any other occupant or user of the Building or any
neighboring building. Tenant shall not place any harmful liquids or other
substances in the drainage system of the Building or use any apparatus,
machinery or other equipment in or about the Premises that may cause substantial
noise or vibration or overload existing electrical systems, or otherwise place
any unusual loads upon the floors, walls, or ceilings of the Premises which may
overload the Premises or jeopardize the structural integrity of the Building or
any part thereof. Tenant shall not make any penetrations of the roof or exterior
of the Building without the prior written approval of Landlord. No materials or
articles of any nature shall be stored upon any portion of the Outside Areas
unless located within an enclosure approved by Landlord.

      9.    Operating Expenses.

            9.1   OPERATING EXPENSES. Tenant shall pay to Landlord as additional
rent hereunder one-half (1/2) of Tenant's Share of the total amount of Operating
Expenses (as defined below) as may be paid or incurred by Landlord during the
term of this Lease.

                  The term "Operating Expenses" shall mean all costs and
disbursements which Landlord shall pay or become obligated to pay in connection
with maintaining, repairing, managing and operating the Project, including,
without limitation (i) Real Property Taxes, (ii) the insurance premiums for
insurance which Landlord is required or entitled to maintain related to the
Project as described below in Paragraph 14, (iii) the maintenance, repair and
operation of the Project, including but not limited to, all labor, materials,
supplies and services, and the cost of all maintenance contracts, used or
consumed in performing Landlord's maintenance and repair obligations hereunder,
(iv) landscaping costs related to the Project, (v) wages, salaries and benefits
of all employees or consultants engaged in the operation, maintenance and
security of the Project, including taxes, insurance and benefits relating
thereto, (vi) any replacements or capital improvements to the Project, except as
otherwise specified in Paragraph 6.2 above or in Paragraph 10 below, (vii)
utility services which are not separately metered to the premises of the tenants
of the Building, and (viii) janitorial services. Additionally, Tenant's Share of
Operating


                                       10

Expenses shall include a management fee for Landlord's management, operation and
administration of the Project equal to five percent (5%) of the total Operating
Expenses hereunder excluding insurance premiums and Real Property Taxes. To the
extent the useful life of any improvement or item repaired or replaced by
Landlord in connection with its maintenance or repair of the Project exceeds
three (3) years, as reasonably determined by Landlord, the cost thereof shall be
amortized, together with interest thereon at the prevailing rate available to
Landlord from commercial banks, over such reasonable period as Landlord shall
determine and such amortized cost shall be included in Operating Expenses. If
the useful life of any such improvement or item repaired or replaced is three
(3) years or less, then the cost thereof shall be deemed expensed and included
immediately in its entirety in Operating Expenses, except as otherwise specified
in Paragraph 6.2 above or in Paragraph 10 below.

                  In addition to the foregoing, Tenant shall reimburse Landlord
in full upon demand for any damage to the Premises, the Building or the Outside
Areas which is caused by Tenant, its agents, employees, contractors or invitees.

                  Notwithstanding anything to the contrary, it is expressly
understood that Operating Expenses do not include (i) amounts due under loans
encumbering the Premises, or payments of rent under ground leases of the
Premises, (ii) depreciation of the Building or of any building service
equipment, (iii) brokerage commissions incurred in connection with leasing all
or any portion of the Building, (iv) attorneys' fees, accounting costs, and
other costs directly related to leasing space in the Building, (v) damage caused
by the active negligence, wilful misconduct, or omissions (subject to Paragraph
32.1) of the Landlord or its employees, agents, or contractors, (vi) damage to
the Project caused by any other tenants of the Project, or their respective
employees, agents, or contractors, and (vii) expenses related to repairing
construction defects in the Building shell.

                  Tenant shall have the right to inspect the books and records
of Landlord relating to the calculation of Operating Expenses no more often than
one time in any twelve month period during the term of the Lease for purposes of
verifying the accuracy of Landlord's calculation of the amount of Operating
Expenses. Tenant shall exercise such right by delivery to Landlord of notice of
Tenant's desire to so inspect such books and records, and dates and times during
normal business hours during which Tenant would like to inspect the same,
whereupon Landlord shall reasonably cooperate with Tenant to provide reasonable
access to such books and records at Landlord's offices.


                                       11

            9.2   MONTHLY PAYMENTS. Tenant shall pay to Landlord on the first
day of each calendar month during the term hereof an amount estimated by
Landlord to be one-twelfth (1/12) of Tenant's Share of one half (1/2) of the
Operating Expenses for such twelve (12) month period. Landlord estimates that
one-twelfth (1/12) of Tenant's Share of one half (1/2) of the Operating Expenses
for the initial year of the term will be $2,387 (based on annual Operating
Expenses for the Project of $132,000). On or before March 15 of each calendar
year during the term hereof Landlord shall furnish Tenant a statement prepared
in accordance with generally accepted accounting principles, consistently
applied, covering the preceding calendar year and the payments made by Tenant
with respect to such period as set forth in this Paragraph 9. If Tenant's
payments for Operating Expenses during said period did not equal one-half (1/2)
of the actual amount of Tenant's share of Operating Expenses, Tenant shall pay
to Landlord the deficiency with its next due installment of Base Rent after
receipt of such statement. If said payments exceed the actual amount due
hereunder, Landlord shall credit the excess against the next installment(s) of
Base Rent. Operating Expenses shall be prorated as of the Commencement Date and
the Expiration Date (or the date of any sooner termination of the term of this
Lease) to reflect the portion of the calendar year occurring within the lease
term.

      10.   Maintenance and Repairs.

            10.1  TENANT'S OBLIGATIONS. Except as otherwise specifically
provided herein, Tenant shall, at Tenant's expense, keep in good and safe
condition, order and repair the Premises and every part thereof, including
without limitation, all plumbing, heating, air conditioning, ventilating, fire
sprinklers, electrical and lighting facilities, systems, appliances, and
equipment within the Premises; and all fixtures, interior walls, interior
surfaces of exterior walls, floors, ceilings, windows, doors, entrances, all
glass (including plate glass), and skylights located within the Premises. Prior
to the Commencement Date or promptly thereafter, Tenant at its sole cost shall
install an electrical meter measuring all electrical service provided to the
Premises, and shall install a new transformer serving only the Premises; such
installation shall be subject to the provisions of Paragraph 11 hereof relating
to alterations to the Premises. Tenant shall, at Tenant's expense, maintain at
all times during the term of this Lease the heating, ventilating and air
conditioning ("HVAC") systems serving the Premises in a manner reasonably
satisfactory to Landlord, which maintenance at a minimum shall include
replacement of filters, oiling and lubricating of machinery, parts replacement,
adjustment of drive belts, oil changes, weatherproofing of all exposed HVAC
equipment and ducts, and other preventive maintenance; provided, however, that
Tenant shall have the benefit of all warranties available to Landlord regarding
the equipment in said systems. Tenant hereby waives the benefit of any statute
now or

                                       12

hereafter in effect which would otherwise afford Tenant the right to make
repairs at Landlord's expense or to terminate this Lease because of Landlord's
failure to keep the Premises in good condition, order and repair. Tenant
specifically waives all rights it may have under Sections 1932(1), 1941, and
1942 of the California Civil Code, and any similar or successor statute or law.

                  Notwithstanding anything to the contrary contained in the
Lease, Tenant shall in no event be responsible for performing, or paying for the
performance of, repair and maintenance of the Premises or the Building to the
extent the same: (i) is caused by the active negligence, wilful misconduct, or
omissions (subject to Paragraph 32.1) of Landlord or its agents, employees or
contractors, (ii) is necessitated by the negligence or wilful misconduct of
other tenants in the Building, or their agents, employees, or contractors; (iii)
is necessitated by the occurrence of any peril required to be insured under
policies of insurance required to be obtained by Landlord under this Lease, or
(iv) results from construction defects of the Building. The liability of Tenant
shall also be limited to the extent Landlord receives reimbursement from others,
including insurers, guarantors, other tenants in the Building, and contractors.

            10.2  LANDLORD'S OBLIGATIONS. Landlord shall keep in good condition,
order and repair the foundation and exterior walls of the Building (excluding
the interior of all walls and the exterior and interior of all windows, doors,
plate glass, and show cases), and the exterior roof of the Building (except that
Tenant shall repair at Tenant's expense any damage caused by the activities of
Tenant, Tenant's HVAC maintenance service contractor, and/or Tenant's other
agents on the roof, including but not limited to the installation of air
conditioning equipment and/or duct work, or other roof penetrations, and
improper flashing or caulking, and any damage to exposed air conditioning
equipment and duct-work installed by or for Tenant). Expenses incurred by
Landlord in connection with the above described obligations shall be Operating
Expenses hereunder, except for expenses incurred in connection with maintaining
the roof structure (but not the roof membrane), foundation and exterior walls of
the Building which shall be borne solely by Landlord. Notwithstanding the
foregoing, Tenant shall not be required to pay as Operating Expenses the cost of
any repair or maintenance respecting the roof membrane which Tenant is able to
demonstrate to the reasonable satisfaction of Landlord is required as a result
of Landlord's activity on the roof or a defect in construction performed by
Landlord. Landlord shall also paint the Building from time to time as reasonably
necessary, and the cost thereof shall be an Operating Expense. Landlord shall
exercise reasonable diligence in performing such repairs as soon as practicable.
However, Landlord shall have no obligation to make repairs under this Paragraph
10.2 until a reasonable time after Landlord's receipt of written notice from
Tenant of the need for such repairs.


                                       13

Except as otherwise specifically provided herein, there shall be no abatement of
rent or other sums payable by Tenant prior to or during any repairs by Tenant or
Landlord, and Tenant waives all claims for loss of business or lost profits
relating to any such repairs.

            10.3  LANDLORD TO MAINTAIN AND CONTROL OUTSIDE AREAS. Landlord shall
maintain the Outside Areas, together with all facilities and improvements now or
hereafter located thereon, and together with all street improvements or other
improvements adjacent thereto as may be required from time to time by
governmental authority. The manner in which such areas shall be maintained and
the expenditures therefor shall be at the sole discretion of Landlord; provided
that Landlord maintains the Outside Areas in such a fashion as achieves
substantially the same level of quality in which Landlord maintained the Outside
Areas during PSC's occupancy of the Premises. Landlord shall at all times have
exclusive control of the Outside Areas and may at any time temporarily close any
part thereof, may exclude and restrain anyone from any part thereof (except the
bona fide customers, employees and invitees of Tenant who use the Outside Areas
in accordance with the rules and regulations that Landlord may from time to time
promulgate), and Landlord may change the configuration of the Outside Areas or
the location of facilities thereon so long as any such change by Landlord does
not unreasonably interfere with Tenant's use of the Premises. Landlord shall
also be entitled to employ third parties to operate and maintain all or any part
of such areas on such terms and conditions as Landlord shall in its sole
discretion deem reasonable and proper. In exercising any such rights, Landlord
shall make a reasonable effort to minimize any disruption of Tenant's business.

            10.4  HVAC REPLACEMENT AND PARKING LOT RESURFACING. If the HVAC
equipment (or any portion thereof) servicing the office portion of the Premises
(as opposed to the manufacturing portion of the Premises, for which Tenant shall
be solely liable for HVAC replacement costs) must be replaced at any time during
the Lease term, or the parking lot adjacent to the Building servicing the
tenants of the Building requires Major Resurfacing (as defined below), as
reasonably determined by Landlord, at any time during the Lease term, then the
cost of such replacement or resurfacing, as the case may be, shall be borne by
both Landlord and Tenant in accordance with the following formula. Tenant shall
pay such portion of the cost which is equal to 43.4% of a fraction, the
numerator of which is the number of years remaining in the Lease term, and the
denominator of which is the useful life (as reasonably determined by Landlord)
of the new HVAC system, or the resurfaced parking lot, as the case may be. In
the event Tenant should exercise any options to extend the Lease term which
extended terms commence after such replacement or resurfacing, then Tenant shall


                                       14

pay to Landlord upon commencement of each such extended term the difference
between the amount owed by Tenant pursuant to the immediately preceding
sentence, and the amount calculated pursuant to the preceding sentence assuming
that the remaining term of the Lease includes the years of such extended term.
For purposes of this subparagraph, "Major Resurfacing" shall be defined to mean
any resurfacing of the parking lot the cost of which exceeds Ten Thousand
Dollars ($10,000.00); to the extent the cost of resurfacing is less than Ten
Thousand Dollars ($10,000.00), then the entire cost shall be an Operating
Expense in the year in which it is incurred by Landlord.

      11.   Alterations.

            11.1  LANDLORD'S CONSENT REQUIRED. Tenant shall not, without
Landlord's prior written consent (which consent shall not unreasonably be
withheld or delayed beyond thirty (30) days after Tenant's written request to
Landlord to make the same) make any alterations, improvements, additions, or
utility installations (collectively called "alterations") in, on or about the
Premises, except for nonstructural alterations which during any twelve (12)
month period, in the aggregate, cost no more than Twenty Thousand Dollars
($20,000). As used in this Paragraph 11.1, the term "utility installation" means
power panels, wiring, fluorescent fixtures, space heaters, conduits, air
conditioning and plumbing. Should Tenant make any alterations requiring the
prior written consent of Landlord without obtaining such consent, Tenant shall
immediately remove the same at Tenant's expense upon demand by Landlord.

            11.2  PLANS AND PERMITS. Any alteration that Tenant shall desire to
make in or about the Premises and which requires the consent of Landlord shall
be presented to Landlord in written form, with proposed detailed plans and
specifications therefor prepared at Tenant's sole expense. Any consent by
Landlord thereto shall be deemed conditioned upon Tenant's acquisition of all
permits required to make such alteration from all appropriate governmental
agencies, the furnishing of copies thereof to Landlord prior to commencement of
the work, and the compliance by Tenant with all conditions of said permits in a
prompt and expeditious manner, all at Tenant's sole expense. Upon completion of
any alterations whether or not Landlord's consent thereto is required, Tenant,
at Tenant's sole cost, shall immediately deliver to Landlord "as-built" plans
and specifications therefor.

            11.3  CONSTRUCTION WORK DONE BY TENANT. All construction work
required or permitted to be done by Tenant shall be performed by licensed
contractors in a prompt, diligent, and good and workmanlike manner, and shall
not materially


                                       15

diminish the value of the Building. Furthermore, all such construction work
shall conform in quality and design with the Premises existing as of the time
such work is performed. In addition, all such construction work shall be
performed in compliance with all applicable statutes, ordinances, regulations,
codes and orders of governmental authorities and insurers of the Premises.
Tenant or its agents shall obtain and pay for all licenses and permits necessary
therefor.

            11.4  ROOF REPAIRS. All installation of air conditioning equipment
and duct work requiring penetration of the roof shall be properly flashed and
caulked. Any electrical or refrigeration conduits or other piping or materials
installed by Tenant in the Building shall be installed beneath the surface of
the roof (and not on the surface of the roof), and Tenant shall thereafter
repair and re-roof the affected portions of the roof surface. Any equipment
placed by Tenant on the roof shall be elevated and supported by Tenant so as not
to inhibit drainage or Landlord's repair of the roof pursuant to Paragraph 10.2.

            11.5  TITLE TO ALTERATIONS. Except as otherwise provided
hereinbelow, Tenant shall at all times retain title to any alterations, and
shall be entitled to claim any depreciation, investment tax credits, and other
tax benefits available in connection therewith. Tenant shall also be entitled to
remove any alterations installed by Tenant at its own expense, provided such
removal can be accomplished without causing damage to structural portions of the
Building, and provided further that Tenant at its sole expense promptly repairs
any and all damage occasioned by such removal. If at the time Tenant installs or
constructs any alterations, Tenant requests and receives Landlord's permission
to leave such alterations on the Premises upon expiration or sooner termination
of the Lease term, then Tenant shall have no obligation to remove the same upon
expiration or sooner termination of the Lease term. If Tenant fails at the time
of installation to request or obtain Landlord's consent to leaving such
alterations on the Premises upon expiration or sooner termination of the Lease
term, then Landlord shall be entitled to require Tenant to remove the same and
restore the Premises to its original condition subject to reasonable wear and
tear, perils, and Acts of God, prior to expiration or promptly after sooner
termination of the Lease term, at Tenant's sole cost and expense. Tenant shall
be entitled to leave the Tenant Improvements in the Premises upon expiration or
sooner termination of the Lease term. Tenant shall be obligated to remove the
Additional Improvements upon expiration or sooner termination of the Lease term.
The rights of Landlord and obligations of Tenant under this paragraph shall
survive termination of the Lease term.

                  All alterations and other property of Tenant which remain on
the Premises upon expiration or sooner termination of the Lease term, subject to
the

                                       16

preceding subparagraph, shall be deemed abandoned by Tenant and at Landlord's
sole election shall be deemed the sole property of Landlord without need for
consideration therefor from Landlord to Tenant.

                  Landlord, within ten (10) days after demand from Tenant, shall
execute and deliver any documents required by any supplier, lessor, or lender in
connection with the installation in the Premises of Tenant's personal property
or Tenant's trade fixtures in which Landlord waives any rights it may have or
require with respect to that property, if the supplier, lessor, or lender agrees
in writing that (a) it will remove that property from the Premises before the
expiration of the Lease term or within thirty (30) days after sooner termination
of the term, provided that if it does not remove the property within said period
it shall have waived any rights it may have had to the property, and (b) it
shall repair any damage to the Premises occasioned by such removal at its sole
cost and expense within five (5) days after such removal.

            11.6  MECHANICS' LIENS. Tenant shall keep the Premises, the
Building, and the Project free from any liens arising out of any work performed,
materials furnished or obligations incurred by Tenant. In the event that Tenant
shall not, within ten (10) days following the imposition of any such lien, cause
the same to be released of record, Landlord shall have, in addition to all other
remedies provided herein and by law, the right, but no obligation, to cause the
same to be released by such means as Landlord shall deem proper, including
payment of the claim giving rise to such lien. All sums paid by Landlord for
such purpose, and all reasonable expenses incurred by it in connection
therewith, shall be payable to Landlord by Tenant on demand with interest at the
rate of ten percent (10%) per annum, or the maximum rate permitted by law,
whichever is less. Tenant shall give Landlord notice of the date of commencement
of any work in the Premises not less than ten (10) days prior thereto, and
Landlord shall have the right to post notices of non-responsibility or similar
notices in or on the Premises in connection therewith.

      12.   UTILITIES. Prior to Tenant's occupancy of the Premises, or promptly
thereafter, Tenant at its sole cost shall separately meter all utilities serving
the Premises. For all periods of time prior to such separate metering, Tenant
shall pay fifty percent (50%) of all utilities costs which are not separately
metered and which are provided to the Building. Such separate metering shall be
deemed an alteration of the Premises which is subject to the provisions of
Paragraph 11 above. Tenant shall pay when due directly to the charging authority
all charges for water, gas, electricity, telephone, refuse pickup, janitorial
services, and all other utilities and services supplied or furnished to the
Premises during the term of this Lease, together with any taxes thereon. In no
event shall Landlord be liable to Tenant for failure or


                                       17

interruption of any such utilities or services, unless caused by the willful
misconduct of Landlord, and no such failure or interruption shall entitle Tenant
to terminate this Lease or to withhold rent or other sums due hereunder.
Landlord shall not be responsible for providing security guards or other
security protection for all or any portion of the Premises, and Tenant shall at
its own expense provide or obtain such security services as Tenant shall desire
to insure the safety of the Premises.

      13.   Indemnity.

            13.1  INDEMNITY BY TENANT. Tenant shall indemnify, protect, defend,
and hold harmless Landlord from and against any and all claims, damages, loss,
proceedings, causes of action, costs, expense or liability due to, but not
limited to, bodily injury, including death resulting at any time therefrom,
and/or property damage, now or hereafter arising from any act, work or things
done or permitted to be done or otherwise suffered, or any omission in or about
the Premises, the Building, or the Project, by Tenant or by any of Tenant's
agents, employees, contractors, or invitees, or from any breach or default by
Tenant in the performance of any obligation on the part of Tenant to be
performed under the terms of this Lease, except to the extent such damage, loss,
expense or liability is caused by the active negligence, willful misconduct or
omission (subject to Paragraph 32.1) of Landlord or its agents, employees or
contractors. Tenant shall also indemnify Landlord from and against all damage,
loss, expense (including without limitation, attorneys' fees, costs of
investigation, and expert witness fees), and liability incurred or suffered by
Landlord in the defense of or arising out of or resulting from any claim or any
action or proceeding brought thereon. In the event any action or proceeding
shall be brought against Landlord by reason of any such claim, Tenant upon
notice from Landlord shall defend the same at Tenant's expense with counsel
reasonably satisfactory to Landlord. The obligations of Tenant contained in this
paragraph shall survive the termination of this Lease.

            13.2  INDEMNITY BY LANDLORD. Landlord hereby indemnifies Tenant from
and against all damages arising out of any damage to any person or property
occurring in, on or about the Premises and the Building resulting from the
active negligence, wilful misconduct, or omissions (subject to Paragraph 32.1)
of Landlord or its employees, agents and contractors, or from a breach of
Landlord's obligations under the Lease, except to the extent caused by the acts
or omissions of Tenant or its authorized representatives. Landlord's obligation
under this paragraph to indemnify Tenant shall be limited to the sum that
exceeds the amount of insurance proceeds, if any, received by Tenant as a result
of such damage.


                                       18

                  Notwithstanding the foregoing or any other provision in this
Lease, Landlord shall in no event be liable to Tenant for lost profits of Tenant
unless the same result from the wilful misconduct of Landlord, and Tenant hereby
releases Landlord from liability for any such loss profits to such extent. This
provision shall not be construed to release Landlord from any claim for damages
arising from Landlord's wilful misconduct, to the extent such damages do not
relate to lost profits.

      14.   Insurance.

            14.1  TENANT'S LIABILITY INSURANCE. Tenant shall, at its sole cost
and expense, obtain and keep in force during the term of this Lease either
Comprehensive General Liability insurance or Commercial General Liability
insurance applying to the use and occupancy of the Premises and the business
operated by Tenant, or any other occupant, on the Premises. Such insurance shall
include Broad Form Contractual liability insurance coverage. Such coverage shall
have a minimum combined single limit of liability of at least Five Million
Dollars ($5,000,000). All such policies shall be written to apply to all bodily
injury, property damage, personal injury and other covered loss, however
occasioned. All such policies shall be endorsed to add Landlord and any lender
or other party having an interest in the Premises named by Landlord as an
additional insured and to provide that any insurance maintained by Landlord
shall be excess insurance only. All such insurance shall provide for
severability of interests; shall provide that an act or omission of one of the
insureds shall not reduce or avoid coverage to the other insureds; and shall
afford coverage for all claims based on acts, omissions, injury and damage,
which claims occurred or arose (or the onset of which occurred or arose) in
whole or in part during the policy period. The limits of all insurance described
in this Paragraph 14.1 shall not, however, limit the liability of Tenant
hereunder.

            14.2  LANDLORD'S PROPERTY INSURANCE. Landlord shall obtain and keep
in force during the term of this Lease a policy or policies of insurance
covering loss or damage to the Project in the amount of the full replacement
value thereof, providing protection against all perils included within the
classification of fire, extended coverage, vandalism, malicious mischief,
special extended perils (all risk), including boiler and machinery coverage and
an inflation endorsement, and, if available, flood and/or earthquake. Such
coverage shall include the Tenant Improvements described on EXHIBIT "C", but
shall exclude coverage of (i) the Additional Improvements described on Exhibit
"D" and all other leasehold improvements, additions, and alterations other than
the Tenant Improvements described on EXHIBIT "C" existing from time to time on
the Premises, and (iii) merchandise, fixtures, equipment and other personal
property of Tenant. In addition, Landlord shall obtain and keep in force,


                                       19

during the term of this Lease, a policy of rental loss insurance covering a
period of one year, commencing on the date of loss, with proceeds payable to
Landlord, which insurance may also cover all Real Property Taxes, insurance
premiums, other Operating Expenses, and other sums payable by Tenant to Landlord
hereunder for said period. The insurance coverage may include sprinkler leakage
insurance if the Building contains fire sprinklers. Tenant shall have no
interest in or right to the proceeds of any such insurance carried by Landlord.

                  Landlord shall make available to Tenant for Tenant's
inspection all insurance bills received by Landlord from time to time relating
to insurance required to be obtained by Landlord pursuant to this paragraph. It
is understood that Landlord's insurance policy covering the Premises shall also
cover the full replacement value of the Tenant Improvements, and that the
proceeds of such insurance shall belong to Landlord and Tenant shall have no
interest therein. In the event Tenant reasonably demonstrates to Landlord that
Landlord can obtain insurance for the Premises, or the Building if Landlord
obtains insurance for the entire Building rather than the Premises alone, at a
rate which is 90% or less of the premiums charged for such insurance as has been
obtained by Landlord, then Landlord at Tenant's written request shall obtain a
policy of property insurance at such lower rate, provided such policy can be
obtained with an insurer authorized to do business in the State of California
which insurer has a financial rating of at least A 14 as rated in the most
recent addition of Best's Insurance Reports, and such policy has reasonably
comparable coverage and deductible amounts. Tenant shall not be required to pay
any increases in property insurance costs to the extent such increases are
caused by other tenants' uses of the Building in which the Premises are located.
Similarly, Tenant shall be solely liable for any increases in property insurance
costs to the extent such increases are caused by Tenant's use of the Premises or
Tenant's activities thereon.

            14.3  TENANT'S PROPERTY INSURANCE. Tenant shall, at Tenant's sole
expense, obtain and keep in force during the term of this Lease, a policy of
fire and extended coverage insurance including a standard "all risk"
endorsement, insuring (i) the Additional Improvements described on EXHIBIT "D"
and all other leasehold improvements, additions, and alterations existing from
time to time in or to the Premises other than the Tenant Improvements described
on EXHIBIT "C", and (iii) merchandise, fixtures, equipment and other personal
property of Tenant within the Premises. Such insurance coverage shall be for the
full replacement value thereof, as the same may increase from time to time due
to inflation or otherwise. The proceeds from any such policies shall be used for
the repair or replacement of such items so insured (except for the proceeds
arising from damage to the Additional Improvements, which may be used as Tenant
desires for purposes which may be


                                       20

unrelated to repair or replacement of the Additional Improvements), and Landlord
shall have no interest in the proceeds of such insurance.

            14.4  PAYMENT. Tenant's Share of the premiums for the insurance
obtained by Landlord pursuant to Paragraph 14.2 shall be deemed an Operating
Expense hereunder. Upon request by Tenant, Landlord shall consult with Tenant
and reasonably cooperate with Tenant to achieve the mix of premium amounts and
deductible amounts for such insurance that are satisfactory to Tenant; provided
that, Landlord's determination of the amounts thereof shall be final and
Tenant's comments regarding same shall be advisory only. Tenant shall pay to
Landlord the entire amount of any deductibles and other amounts not paid by
Landlord's insurance carriers relating to claims under Landlord's insurance
policies resulting from the acts or omissions of Tenant, or its agents,
employees, and invitees. Tenant shall pay such deductibles to Landlord within
thirty (30) days after receipt by Tenant of a copy of reasonable evidence of the
amount due. Notwithstanding the foregoing, Landlord may obtain liability
insurance and property insurance for the Project separately, or together with
other buildings and improvements under blanket policies of insurance. In the
latter case Tenant shall be liable for only such portion of the premiums for
such blanket policies as are allocable to the Premises, as reasonably determined
by the insurer or Landlord. If the term of this Lease does not commence or
expire concurrently with the commencement or expiration, respectively, of the
period covered by such insurance, Tenant's liability for premiums shall be
prorated on an annual basis.

            14.5  INSURANCE POLICIES. The insurance required to be obtained by
Tenant pursuant to this paragraph shall be primary insurance and (a) shall
provide that the insurer shall be liable for the full amount of the loss up to
and including the total amount of liability set forth in the declarations
without the right of contribution from any other insurance coverage of Landlord,
(b) shall be in a form and contain a deductible amount satisfactory to Landlord,
(c) shall be carried with companies acceptable to Landlord, and (d) shall
specifically provide that such policies shall not be subject to cancellation,
reduction of coverage or other change except after at least fifteen (15) days
prior written notice to Landlord. The policy or policies, or duly executed
certificates for them, together with satisfactory evidence of payment of the
premium thereon, shall be deposited with Landlord on or prior to the
Commencement Date, and upon each renewal of such policies, which shall be
effected not less than fifteen (15) days prior to the expiration date of the
term of such coverage. Tenant shall not do or permit to be done anything which
shall invalidate any of the insurance policies referred to in this Paragraph 14.


                                       21

            14.6  WAIVER OF SUBROGATION. Tenant and Landlord each hereby waives
any and all rights of recovery against the other, or against the officers,
employees, agents and representatives of the other, for loss of or damage to the
property of the waiving party or the property of others under its control, where
such loss or damage is insured against under any insurance policy carried by
Landlord or Tenant and in force at the time of such loss or damage. Tenant and
Landlord shall, upon obtaining the policies of insurance required hereunder,
give notice to the insurance carrier or carriers that the foregoing mutual
waiver of subrogation is contained in this Lease. Landlord and Tenant shall use
their best efforts to cause each insurance policy obtained by such party to
provide that the insurance company waives all rights of recovery by way of
subrogation against the other party in connection with any damage covered by
such policy and, if any such waiver of subrogation is not obtained, shall
promptly notify the other party of such fact.

            14.7  NO LIMITATION OF LIABILITY. Landlord makes no representation
that the limits of liability specified to be carried by Tenant or Landlord under
the terms of this Lease are adequate to protect any party. If Tenant believes
that the insurance coverage required under this Lease is insufficient to
adequately protect Tenant, Tenant shall provide, at its own expense, such
additional insurance as Tenant deems adequate.

      15.   Damage or Destruction.

            15.1  PARTIAL DAMAGE - INSURED. Subject to the provisions of
Paragraphs 15.3 and 15.4 below, if the Premises or the Building, as the case may
be, are damaged such that restoration thereof can in Landlord's reasonable
estimation be completed within two hundred ten (210) days, and the damage is
caused by a peril required to be insured against by Landlord pursuant to
Paragraph 14, Landlord shall at Landlord's expense repair such damage as soon as
reasonably possible and this Lease shall continue in full force and effect. In
the event Landlord maintains earthquake insurance (which the parties acknowledge
Landlord is not obligated by this Lease to carry), then subject to the
provisions of Paragraphs 15.3 and 15.4 below, if the Premises or the Building,
as the case may be, are damaged such that restoration thereof can in Landlord's
reasonable estimation be completed within two hundred ten (210) days, and the
damage is caused by earthquake, Landlord shall, subject to the following
provisions of this Paragraph 15.1, repair such damage as soon as reasonably
possible and this Lease shall continue in full force and effect. At such time as
the amount of the deductible for the earthquake damage is determined by the
insurance company and Landlord agrees to such amount, Landlord shall deliver
notice thereof to Tenant. On or before the Tenant's Share Payment Date (as
defined below), Tenant



                                       22

shall deliver to a depository in accordance with the provisions of Paragraph
15.10 the following sums in cash or other readily available funds: (i) 43.4% of
the amount by which the amount of such deductible exceeds Fifty Thousand Dollars
($50,000), provided that Tenant shall not be obligated to pay more than 43.4% of
Fifty Thousand Dollars ($50,000) under this subparagraph (i), and (ii) 43.4% of
one half of the amount by which such deductible exceeds One Hundred Thousand
Dollars ($100,000). The formula set forth in the preceding sentence is based
upon the Landlord paying the first Fifty Thousand Dollars ($50,000) of the
earthquake deductible, all tenants in the Building together paying the next
Fifty Thousand Dollars ($50,000) of the earthquake deductible, and Landlord on
the one hand and said Building tenants on the other hand each paying one half of
any earthquake deductible amount exceeding One Hundred Thousand Dollars
($100,000) (all such amounts payable by all tenants of the Building herein
called the "Aggregate Building Tenants' Share"). The "Tenant's Share Payment
Date" shall mean (i) fifteen (15) days after Landlord delivers notice to Tenant
of the deductible amount if the amount of the earthquake deductible payable by
Tenant pursuant to the foregoing is Fifty Thousand Dollars ($50,000) or less,
and (ii) forty five (45) days after Landlord delivers notice to Tenant of the
deductible amount if the amount payable by Tenant is more than Fifty Thousand
Dollars ($50,000). In the event Tenant fails to pay such amount for any reason
by the Tenant's Share Payment Date, or in the event Landlord does not receive by
the Tenant's Share Payment Date the Aggregate Building Tenants' Share, then
Landlord shall have no obligation to commence or complete repair of such
earthquake damage, and shall be entitled to terminate this Lease by delivery to
Tenant of notice of such termination within ten (10) days after the Tenant's
Share Payment Date; provided that Landlord shall be entitled to, but shall have
no obligation to, repair all such earthquake damage at Landlord's expense,
including payment of the deductible, such election to so repair to be made by
Landlord's delivery of notice thereof to Tenant within ten (10) days after the
Tenant's Share Payment Date, in which event this Lease shall remain in full
force and effect.

            15.2  PARTIAL DAMAGE - UNINSURED. Subject to the provisions of
Paragraphs 15.3 and 15.4, if at any time during the term hereof the Premises are
damaged and the damage is caused by a peril (other than earthquake) not required
to be insured by Landlord pursuant to Paragraph 14, Landlord may at Landlord's
option either (a) repair such damage as soon as reasonably possible at
Landlord's expense, in which event this Lease shall continue in full force and
effect, or (b) give written notice of termination of this Lease to Tenant within
thirty (30) days after the date of the occurrence of such damage, with the
effective date of such termination to be the date of the occurrence of such
damage. In the event Landlord gives such notice of termination of this Lease,
Tenant shall have the right, within ten (10) days after receipt


                                       23

of such notice, to agree in writing on a basis satisfactory to Landlord to pay
for the entire cost of repairing such damage less only the amount of insurance
proceeds, if any, received by Landlord, in which event the notice of termination
shall be ineffective and this Lease shall continue in full force and effect, and
Landlord shall proceed to make such repairs as soon as reasonably possible. If
Tenant does not give such notice within such ten (10) day period, this Lease
shall be terminated pursuant to such notice of termination by Landlord.

            15.3  TOTAL DESTRUCTION. If at any time during the term hereof the
Premises are destroyed such that restoration thereof cannot in Landlord's
reasonable estimation be completed in two hundred ten (210) days, from any cause
whether or not covered by the insurance maintained pursuant to Paragraph 14,
this Lease shall at the election of Landlord or Tenant terminate as of the date
of such destruction. Landlord and Tenant shall exercise their respective rights
to terminate this Lease under this subparagraph 15.3 by delivery of notice of
termination to the other within thirty (30) days after Landlord notifies Tenant
of the estimated period of restoration. In the event neither party elects to so
terminate this Lease, Landlord shall at Landlord's expense repair such damage,
and restore the Premises and the Tenant Improvements to their condition existing
immediately prior to such damage as soon as reasonably possible, and this Lease
shall continue in full force and effect.

            15.4  DAMAGE NEAR END OF TERM. If the Premises are destroyed or
damaged in whole or in part to the extent of One Hundred Thousand Dollars
($100,00.00) or more whether from an insured or uninsured casualty, during the
last year of the term of this Lease, either party may at its option cancel and
terminate this Lease as of the date of occurrence of such damage by giving
written notice to the other party within thirty (30) days after the date of
occurrence of such damage. Notwithstanding the foregoing, if Tenant is then
entitled to exercise any option to extend the term of this Lease pursuant to
other provisions of this Lease, and Tenant exercises such option in accordance
with such provision, then this Lease shall not be terminated under this
subparagraph (although it may be terminated in accordance with subparagraph 15.3
above or other provisions of this Lease, to the extent applicable).

            15.5  ABATEMENT OF RENT. Notwithstanding anything to the contrary
contained in this Lease, if the Premises are damaged, the Base Rent payable
hereunder for the period commencing on the occurrence of such damage shall be
abated until completion of repair or restoration of such damage, or termination
of the Lease (if the Lease is terminated pursuant to other provisions of this
Lease). Such abatement of Base Rent shall be in proportion to the extent to
which Tenant's use of the Premises is impaired during said period of time;
provided that, nothing herein shall



                                       24

be construed to preclude Landlord from being entitled to collect the full amount
of any rental loss insurance proceeds. In addition to abatement of Base Rent,
Tenant's obligation to pay Operating Expenses shall also be abated to the extent
of proceeds therefor, if any, received by Landlord under the rent abatement
policy required to be maintained by Landlord under Paragraph 14.2 above. Except
for such abatement of Base Rent and Operating Expenses, if any, and subject to
Paragraph 13.2, Tenant shall have no claim against Landlord for any damage
suffered by reason of any such damage, destruction, repair or restoration.

            15.6  WAIVER. Tenant waives the provisions of California Civil Code
Sections 1932(2) and 1933(4), and any similar or successor statutes relating to
termination of leases when the thing leased is substantially or entirely
destroyed, and agrees that any such occurrence shall instead be governed by the
terms of this Lease.

            15.7  TENANT'S PROPERTY. Landlord's obligation to rebuild or restore
shall not include restoration of the Additional Improvements, or Tenant's trade
fixtures, equipment, merchandise, or any other improvements, alterations or
additions made by Tenant to the Premises after the Commencement Date or made by
PSC at any time during its occupancy of the Premises from 1985 through May of
1995.

            15.8  NOTICE OF DAMAGE. Tenant shall notify Landlord within five (5)
days after the occurrence thereof of any damage to all or any portion of the
Premises. In no event shall Landlord have any obligation to repair or restore
the Premises pursuant to this Paragraph 15 until a reasonable period of time
after Landlord's receipt of notice from Tenant of the nature and scope of any
damage to the Premises, and a reasonable period of time to collect insurance
proceeds arising from such damage (unless such damage is clearly not covered by
insurance then in effect covering the Premises). Landlord shall proceed
diligently to collect insurance proceeds, and shall commence any obligation it
may have to repair the Premises as promptly as reasonably possible.

            15.9  REPLACEMENT COST. The determination by a third party expert or
consultant, selected by Landlord in its reasonable discretion, of the estimated
period of repair of any damage shall be conclusive for purposes of this
Paragraph 15. Such determination shall be made within thirty (30) days of the
date of damage, provided Tenant notifies Landlord of such damage in accordance
with subparagraph 15.8 above.

            15.10 DISBURSEMENT ACCOUNT. In the event Landlord is required to
restore the Premises pursuant to any of the provisions of this Paragraph 15,
then Landlord shall deposit any insurance proceeds received in connection
therewith with


                                       25

an institutional trustee or other depository reasonably acceptable to Tenant,
and the proceeds of such insurance shall be drawn from time to time to cover
costs of such restoration only upon submission by Landlord of invoices for such
costs or other reasonable evidence of Landlord of the costs incurred to the date
of such requested draw.

      16.   Condemnation.

            16.1  PARTIAL TAKING. Subject to Paragraph 16.5, if part of the
Premises is taken for any public or quasi-public use, under any statute or right
of eminent domain (collectively a "taking"), and a part of the Premises remains
which is reasonably suitable for Tenant's continued occupancy for the uses
permitted by this Lease, and a portion of the parking area within the Project
remains which is equivalent to at least eighty percent (80%) of the parking area
in the Project as of the Commencement Date, this Lease shall, as to the part so
taken, terminate as of the date the condemnor or purchaser takes possession of
the property being taken, and the monthly Base Rent payable hereunder shall be
reduced in the same proportion that the floor area of the portion of the
Premises so taken bears to the floor area of the Premises immediately prior to
such taking. Landlord shall, at its own cost and expense, make all necessary
repairs or alterations to the Premises in order to make the portion of the
Premises not taken a complete architectural unit. Such work shall not, however,
exceed the scope of the work done by Landlord in originally constructing the
Premises. Each party hereto waives the provisions of California Code of Civil
Procedure Section 1265.130 allowing either party to petition the superior court
to terminate this Lease in the event of a partial taking of the Premises.

            16.2  TOTAL TAKING. Subject to Paragraph 16.5, if all of the
Premises are taken, or such part thereof is taken so that there does not remain
a portion of the Premises suitable for Tenant's continued occupancy for the uses
permitted hereunder, or more than twenty percent (20%) of the parking area in
the Project as of the Commencement Date is taken, such taking shall be treated
as a total taking and this Lease shall terminate upon the date possession shall
be taken by the condemning authority.

            16.3  DISTRIBUTION OF AWARD. All compensation awarded upon a taking
governed by Paragraph 16.1 or Paragraph 16.2 shall belong to and be paid to
Landlord, except that Tenant shall be entitled to make a separate claim to the
taking authority for all losses it suffers as a consequence of the taking,
including losses relating to loss of use of the Additional Improvements.


                                       26

            16.4  SALE UNDER THREAT OF CONDEMNATION. A sale by Landlord to any
authority having the power of eminent domain, either under threat of
condemnation or while condemnation proceedings are pending, shall be deemed a
taking under the power of eminent domain for purposes of this Paragraph 16.

            16.5  TEMPORARY TAKING. If all or any part of the Premises is
occupied, taken, or appropriated by military or other public or quasi-public use
or other governmental authority for less than one hundred eighty (180)
consecutive days, it shall not constitute a taking of the Premises which would
be governed by Paragraph 16.1 or Paragraph 16.2. In such event, during such a
"temporary taking," all of the provisions of this Lease shall remain in force
and effect, except that the monthly Base Rent and Operating Expenses payable
during such temporary taking shall be reduced in the same proportion that the
floor area of the portion of the Premises so occupied, taken, or appropriated
bears to the floor area of the Premises as of the day immediately preceding the
occupation, taking, or appropriation. Any award that may be paid in connection
with such a temporary taking shall be paid to Landlord. In the event a taking
which appears, at its commencement, to be only a temporary taking nevertheless
continues for one hundred eighty (180) consecutive days or more, a partial or
total taking, as the case may be, shall be deemed to have occurred on the one
hundred eightieth (180th) consecutive day of such taking, and shall be governed
by the provisions of either Paragraph 16.1 or Paragraph 16.2 as the case may be.

      17.   Assignment and Subletting.

            17.1  PROHIBITION OF ASSIGNMENT AND SUBLETTING. Tenant shall not
assign this Lease, or any interest therein, voluntarily or involuntarily, and
shall not sublet the Premises or any part thereof, or any right or privilege
appurtenant thereto, or suffer any other person (the agents and servants of
Tenant excepted) to occupy or use the Premises, or any portion thereof, without
the prior written consent of Landlord in each instance pursuant to the terms and
conditions set forth below, which consent shall not unreasonably be withheld or
delayed beyond the twenty (20) day period specified in Paragraph 17.2. Any
assignment or subletting by Tenant without the written consent of Landlord shall
be void and shall, at the option of Landlord, terminate this Lease.

            17.2  DOCUMENTATION. Prior to any assignment or sublease which
Tenant desires to make, Tenant shall provide to Landlord the name and address of
the proposed assignee or sublessee, a statement of the proposed use of the
Premises by the assignee or sublessee (including an indication of the extent to
and manner in which Hazardous Materials will be utilized), and true and complete
copies of all documents relating to Tenant's prospective agreement to assign or
sublease, and shall specify all


                                       27

consideration to be received by Tenant for such assignment or sublease in the
form of lump sum payments, installments of rent, or otherwise. For purposes of
this Paragraph 17, the term "consideration" shall include, without limitation,
all monies or other consideration of any kind, if such sums are related to
Tenant's interest in this Lease or in the Premises, including but not limited
to, bonus money, and payments (in excess of book value thereof) for Tenant's
assets, fixtures, inventory, accounts, good will, equipment, furniture, general
intangibles, and any capital stock or other equity ownership of Tenant. Within
twenty (20) days after the receipt of such written notice, Landlord shall either
consent in writing to such proposed assignment or sublease subject to the terms
and conditions hereinafter set forth, or notify Tenant in writing that Landlord
refuses such consent, specifying reasonable grounds for such refusal.

            17.3  TERMS AND CONDITIONS. As a condition to Landlord's granting
its consent to any assignment or sublease, Tenant and the proposed assignee or
sublessee must demonstrate to Landlord's reasonable satisfaction that the
assignee or sublessee is financially responsible and that the proposed use does
not pose an unreasonable risk (as determined by Landlord in its reasonable
discretion) of contamination of the Project with Hazardous Materials and is not
otherwise injurious to the Premises. Without limiting the generality of the
foregoing, Landlord shall be entitled to withhold consent to any proposed
assignment of this Lease unless Tenant demonstrates to the reasonable
satisfaction of Landlord that the proposed assignee has a net worth equal to at
least the greater of (a) Eleven Million Dollars ($11,000,000.00), or (b) such
greater net worth as Analog Devices, Inc. or its successor may have at the time
of such proposed assignment, up to Eighteen Million Dollars ($18,000,000.00). As
a condition for granting its consent to any proposed assignment or subletting,
Landlord may require that Tenant agree to pay to Landlord, as additional rent,
as and when received by Tenant, and after first deducting reasonable real estate
brokerage commissions and attorneys' fees, if any, incurred in connection with
such assignment or subletting, fifty percent (50%) of the excess, if any, of (i)
the fair market value rent (triple net) of the Premises, determined as set forth
below, assuming such amount is payable for the duration of the term of such
assignment or sublease, over (ii) the Base Rent payable by Tenant to Landlord
under the Lease at the time of such sublease or assignment, assuming such amount
is payable for the duration of the term of such assignment or sublease. The fair
market value rent for the Premises, for purposes of the preceding sentence,
shall be determined without regard to the value added to the Premises by the
specialized additions and improvements to the Premises installed by Tenant at
its own expense or previously installed by PSC at PSC's expense solely for its
manufacturing business on the Premises, such as clean rooms, process equipment,
and trade fixtures. In the event Landlord and Tenant are unable to agree upon
the fair market value rent

                                       28

of the Premises, the dispute shall be arbitrated in accordance with the rules of
the American Arbitration Association.

                  Tenant may assign its interest in the Lease without the prior
written consent of Landlord to any corporation which controls or is controlled
by Analog Devices, Inc., or any corporation which results from a merger or
consolidation with Analog Devices, Inc.; provided that such assignment is made
to an entity that satisfies the net worth criteria set forth hereinabove.

                  Each assignment or sublease agreement to which Landlord has
consented shall be an instrument in writing in form satisfactory to Landlord,
and shall be executed by both Tenant and the assignee or sublessee, as the case
may be. Each such assignment or sublease agreement shall recite that it is and
shall be subject and subordinate to the provisions of this Lease, that the
assignee or sublessee accepts such assignment or sublease and agrees to perform
all of the obligations of Tenant hereunder, and that the termination of this
Lease shall, at Landlord's sole election, constitute a termination of every such
assignment or sublease. In the event Landlord shall consent to an assignment or
sublease, Analog Devices, Inc. shall nonetheless remain primarily liable for all
obligations and liabilities of Tenant under this Lease, including but not
limited to the payment of rent.

      18.   Events of Default and Remedies.

            18.1  EVENTS OF DEFAULT. A breach of this Lease shall exist if any
of the following events (hereinafter referred to as "Event of Default") shall
occur:

                  (1)   Failure of Tenant to pay within five (5) days after
delivery of notice from Landlord that any installment of rent of other payment
required to be made by Tenant hereunder is due;

                  (2)   Tenant's failure to perform any other term, covenant or
condition contained in this Lease and such failure shall have continued for
thirty (30) days after written notice of such failure is delivered to Tenant or
such longer period as may reasonably be necessary to cure such failure provided
Tenant commences such cure within said thirty (30) days and thereafter
diligently prosecutes the same to completion;

                  (3)   Tenant's vacating or abandonment of Premises;

                  (4)   Tenant's assignment of its assets for the benefit of its
creditors;



                                       29

                  (5)   The sequestration of, attachment of, or execution on,
any substantial part of the property of Tenant or on a property essential to the
conduct of Tenant's business, shall have occurred and Tenant shall have failed
to obtain a return or release of such property within thirty (30) days
thereafter, or prior to sale pursuant to such sequestration, attachment of
whichever is earlier; or

                  (6)   A court having jurisdiction shall have made or entered
any decree or order (a) adjudging Tenant to be bankrupt or insolvent, (b)
approving as properly filed a petition seeking reorganization of Tenant or an
arrangement under the bankruptcy laws or any other applicable debtors' relief
law or statute of the United States or any State thereof, (c) appointing a
receiver, trustee or assignee of Tenant in bankruptcy or insolvency or for its
property, or (d) directing the winding up or liquidation of Tenant; and such
decree or order shall have continued for a period of thirty (30) days; or Tenant
shall have voluntarily submitted to or filed a petition seeking any such decree
of order.

            18.2  REMEDIES. Upon any Event of Default, Landlord shall have the
following remedies, in addition to all other rights and remedies provided by
law, to which Landlord may resort cumulatively, or in the alternative:

                  (1)   RECOVERY OF RENT. Landlord shall be entitled to keep
this Lease in full force and effect (whether or not Tenant shall have abandoned
the Premises) and to enforce all of its rights and remedies under this Lease,
including the right to recover rent and other sums as they become due, plus
interest at the rate of ten percent (10%) per annum from the due date of each
installment of rent or other sum until paid.

                  (2)   TERMINATION. Landlord may terminate this Lease by giving
Tenant written notice of termination. On the giving of such notice all Tenant's
rights in the Premises and the Building and parcel of which the Premises are a
part shall terminate. Upon the giving of the notice of termination, Tenant shall
surrender and vacate the Premises in the condition required by Paragraph 26, and
Landlord may reenter and take possession of the Premises and all the remaining
improvements and property and eject Tenant or any of Tenant's subtenants,
assignees or other person or persons claiming any right under or through Tenant
or eject some and not others or eject none. This Lease may also be terminated by
a judgement specifically providing for termination. Any termination under this
paragraph shall not release Tenant from the payment of any sum then due Landlord
or from any claim for damages or rent previously accrued or then accruing
against Tenant. In no event shall any one or more of the following actions by
Landlord constitute a termination of this Lease:


                                       30

                        (a)   maintenance and preservation of the Premises;

                        (b)   efforts to relet the Premises;

                        (c)   appointment of a receiver in order to protect
Landlord's interest hereunder;

                        (d)   consent to any subletting of the Premises or
assignment of this Lease by Tenant, whether pursuant to provisions hereof
concerning subletting and assignment or otherwise; or

                        (e)   any other action by Landlord or Landlord's agents
intended to mitigate the adverse effects from any breach of this Lease by
Tenant.

                  (3)   DAMAGES. In the event this Lease is terminated pursuant
to subparagraph 18.2(2) above, Landlord shall be entitled to damages in the
following sums: (a) the worth at the time of award of the unpaid rent which had
been earned at the time of termination; plus

                        (b)   the worth at the time of award of the amount by
which the unpaid rent which would have been earned after termination until the
time of award exceeds the amount of such rental loss that Tenant proves could
have been reasonably avoided; plus

                        (c)   the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that Tenant proves could be reasonably
avoided; and

                        (d)   any other amounts necessary to compensate Landlord
for all the detriment proximately caused by Tenant's failure to perform Tenant's
obligations under this Lease, or which in the ordinary course of things would be
likely to result therefrom including, without limitation, the following: (i)
expenses for cleaning, repairing or restoring the Premises; (ii) expenses for
altering, remodeling or otherwise improving the Premises for the purposes of
reletting; (iii) costs of carrying the Premises such as taxes and insurance
premiums thereon, utilities and security precautions; (iv) expenses in retaking
possession of the Premises; (v) attorneys' fees and court costs; and (vi) any
unamortized real estate brokerage commission paid in connection with this Lease.


                                       31

                        (e)   The "worth at the time of award" of the amounts
referred to in subparagraphs (a) and (b) of this paragraph is computed by
allowing interest at the rate of ten percent (10%) per annum. The "worth at the
time of award" of the amount referred to in subparagraph (c) of this paragraph
is computed by discounting such amount at the discount rate of the Federal
Reserve Board of San Francisco at the time of award plus one percent (1%). The
term "rent" as used in this paragraph shall include all sums required to be paid
by Tenant to Landlord pursuant to the terms of this Lease.

      19.   ADVERTISEMENTS AND SIGNS. Tenant shall not place or permit to be
placed any sign, display, advertisement, or decoration ("sign") on the exterior
of the Building, or elsewhere in the Project or on the Premises, without the
prior written consent of Landlord as to the color, size, style, character,
content, and location of each such sign. Upon termination of this Lease, Tenant
shall remove any sign which it has placed in the Project or on the Premises or
the Building, and shall repair any damage caused by the installation or removal
of such sign.

      20.   ENTRY BY LANDLORD. Landlord and its agents shall be entitled to
enter into and upon the Premises at all reasonable times, upon reasonable notice
(except in the case of an emergency, in which event no notice shall be
required), for the following purposes: (i) to perform Landlord's maintenance and
repair responsibilities; (ii) to post notices of non-responsibility for
alterations, additions, or repairs; or (iii) to place upon the Premises any
ordinary "for sale" signs and to show the Premises to prospective purchasers or
lenders; and, during the ninety (90) day period prior to the expiration of this
Lease, or upon any Event of Default, to place upon the Premises any usual or
ordinary "for lease" signs and exhibit the Premises to prospective tenants at
reasonable hours.

            Landlord's rights of entry as set forth in this Paragraph 20 shall
be subject to the reasonable security regulations of Tenant, and to the
requirement that Landlord use reasonable efforts to minimize interference with
Tenant's business activities on the Premises.

      21.   Subordination and Attornment.

            Notwithstanding anything contained in this Lease, and except with
respect to any existing deeds of trust or other liens encumbering the Project or
any portion thereof as of the Commencement Date (which the parties acknowledge
are prior to this Lease, subject to such rights as Tenant may receive in the
event a non-disturbance agreement is obtained from the beneficiary of such deed
of trust or other lienholder


                                       32

concurrently with the execution of this Lease), this Lease shall not be subject
to or subordinate to any ground or underlying lease or to any lien, mortgage,
deed of trust, or security interest now or hereafter affecting the Premises, nor
shall Tenant be required to execute any documents subordinating this Lease,
unless the ground lessor, lender, or other holder of the interest to which this
Lease shall be subordinated agrees to execute a recognition and non-disturbance
agreement in substantially the form set forth on EXHIBIT "E".

      22.   ESTOPPEL CERTIFICATES AND FINANCIAL STATEMENTS. Tenant shall within
seven (7) days following request by Landlord: (a) execute and deliver to
Landlord any documents, including estoppel certificates, in the form presented
to Tenant by Landlord (1) certifying that this Lease has not been modified and
is 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, (2) stating the date to which the rent and other charges are paid in
advance, if at all, (3) acknowledging that there are not, to Tenant's knowledge,
any uncured defaults on the part of Landlord hereunder, or if there are uncured
defaults on the part of Landlord, stating the nature of such uncured defaults,
and (4) evidencing the status of this Lease as may be required either by a
lender making a loan to Landlord to be secured by a deed of trust or mortgage
encumbering the premises or a purchaser of the premises from Landlord; and (b)
deliver to Landlord the best available current (and public, if the stock of
Tenant is publicly traded over a United States nationally recognized stock
exchange) financial statements of Tenant with an opinion of a certified public
accountant, if available, including a balance sheet and profit and loss
statement for the then current fiscal year, and the two (2) immediately prior
fiscal years (if available), all prepared in accordance with generally accepted
accounting principles consistently applied. Landlord shall only be entitled to
request such financial statements in connection with an intended disposition or
refinancing of the Building.

Landlord shall within seven (7) days following request by Tenant, provided such
request is made only in connection with a proposed assignment or sublease of
Tenant's interest in this Lease pursuant to Paragraph 17 above: (a) execute and
deliver to Tenant an estoppel certificate in the form presented to Landlord by
Tenant (1) certifying that this Lease has not been modified and is 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, (2)
stating the date to which the rent and other charges are paid in advance, if at
all, and (3) acknowledging that there are not, to Landlord's knowledge, any
uncured defaults on the part of Tenant hereunder, or if there are uncured
defaults on the part of Tenant, stating the nature of such uncured defaults.


                                       33

      23.   NOTICES. Any notice, approval, request, demand, or consent
(collectively "notice") required or desired to be given under this Lease shall
be in writing and shall be personally served or delivered by commercial courier
(with signed receipt) or United States mail, registered or certified, postage
prepaid, and addressed to the party to be served at the last address given by
that party to the other party under the provisions of this paragraph. At the
date of execution of this Lease, the addresses of Landlord and Tenant are as set
forth above in the preamble to this Lease. Either party may change its address
by notice to the other party. Any notice delivered by United States mail
pursuant to this paragraph shall be deemed to have been delivered five (5) days
after the posted date of mailing.

      24.   WAIVER. The waiver by either party of any breach of any term,
covenant, or condition herein contained shall not be deemed to be a waiver of
such term, covenant or condition or any subsequent breach of the same or any
other term, covenant or condition herein contained. The subsequent acceptance of
rent hereunder by Landlord shall not be deemed to be a waiver of any preceding
breach by Tenant of any term, covenant or condition of this Lease, other than
the failure of Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
rent. No term, covenant or condition shall be deemed to have been waived by
either party unless such waiver is in writing and signed by the party making
such waiver.

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

      26.   SURRENDER. Tenant shall, upon expiration or sooner termination of
this Lease, surrender the Premises to Landlord with all Additional Improvements
removed and all damage occasioned by such removal repaired, and otherwise in
good and clean


                                       34

broom swept condition (reasonable wear and tear and damage due to causes beyond
the reasonable control of Tenant excepted) with the HVAC equipment serving the
Premises in operating order and in good repair. Tenant, on or before the
expiration or sooner termination of this Lease, shall remove all of its personal
property and trade fixtures from the Premises. If the Premises are not so
surrendered at the expiration or sooner termination of this Lease, Tenant shall
indemnify Landlord against loss or liability resulting from delay by Tenant in
so surrendering the Premises, including without limitation, any claims made by
any succeeding tenant founded on such delay, and losses to Landlord due to lost
opportunities to lease to succeeding tenants.

      27.   HOLDING OVER. This Lease shall terminate without further notice at
the expiration of the Lease term. Any holding over by Tenant after expiration
shall not constitute a renewal or extension of the Lease term or give Tenant any
rights in or to the Premises unless otherwise expressly provided in this Lease.
Any holding over after expiration of the Lease term with the express written
consent of Landlord shall be construed to be a tenancy from month to month, at
one hundred fifty percent (150%) of the monthly Base Rent for the last month of
the Lease term, and shall otherwise be on the terms and conditions herein
specified insofar as applicable, unless otherwise mutually agreed in writing by
the parties.

      28.   TRANSFER OF PREMISES BY LANDLORD. The term "Landlord" as used in
this Lease, so far as the covenants or obligations on the part of Landlord are
concerned, shall be limited to mean and include only the owner at the time in
question of the fee title to the Premises. In the event of any transfer of such
fee title, the Landlord herein named (and in case of any subsequent transfer or
conveyance, the then grantor) shall after the date of such transfer or
conveyance be automatically freed and relieved of all liability with respect to
performance of any covenants or obligations on the part of Landlord contained in
this Lease thereafter to be performed; provided, that any funds in the hands of
Landlord or the then grantor at the time of such transfer in which Tenant has an
interest, shall be turned over to the grantee. The covenants and obligations
contained in this Lease on the part of Landlord shall, subject to the foregoing,
be binding upon each Landlord hereunder only during his or its respective period
of ownership.

      29.   Option(s) to Extend Term.

            29.1  EXERCISE OF OPTION. Subject to the provisions of this
Paragraph 29, Tenant shall have the right to extend the term of this Lease for
three (3) additional periods of five (5) years each, unless the term is sooner
terminated as provided in this Lease. Unless otherwise expressly agreed in
writing by the parties hereto, the term of


                                       35

this Lease shall in no event extend beyond March 31, 2015. Tenant shall exercise
each of such rights, if at all, only by giving Landlord written notice of
exercise of such right on or before nine (9) months prior to the then scheduled
expiration date of the Lease term, and only if Tenant is not in default under
this Lease when Tenant exercises such right (provided, Tenant has received
notice of such default and has not cured said default within the time permitted
for such cure). If Tenant fails to exercise any such rights to extend in
accordance with this Paragraph 29, such right shall terminate. The second right
to extend may be exercised only if the first right to extend has previously been
properly exercised, and the third right to extend may be exercised only if the
second right to extend has previously been properly exercised. If Tenant
exercises any such rights in accordance with this Paragraph 29, the term of this
Lease shall be extended for one period of five (5) years subject to the
agreements, covenants, conditions, and provisions set forth in this Lease,
except for the amount of Base Rent payable by Tenant, which shall be determined
as set forth in Paragraph 29.2.

            29.2  RENT DURING EXTENDED TERM. The monthly Base Rent during each
such extended term of this Lease shall initially be equal to the fair market
rent of the Premises as of the commencement date of such extended term. Such
fair market rent shall take into account the rent adjustment mechanism to be
employed during such extended term.

                  The parties shall have thirty (30) days after Landlord
receives notice of Tenant's exercise of its right to extend the term in which to
agree on minimum monthly Base Rent during the extended term. If the parties
agree on the minimum monthly Base Rent for the extended term during such thirty
(30) day period, they shall immediately execute an amendment to this Lease
stating the minimum monthly Base Rent for such extended term.

                  If the parties are unable to agree on the minimum monthly Base
Rent for the extended term within such thirty (30) day period, then within said
thirty (30) days each party, at its cost and by giving notice to the other
party, shall appoint an appraiser with at least five (5) years' full time
commercial appraisal or brokerage experience in the Sunnyvale area to appraise
and set the minimum monthly Base Rent for the extended term. Said appraisers
shall be instructed to determine the fair market rent for the Premises within
thirty (30) days after their appointment, and to base their determination on the
rent which will be applicable as of the commencement of the applicable extended
term for comparable space in comparable buildings in comparable geographic areas
leased on terms comparable to this Lease, taking into account the rent
adjustment mechanism to be employed during such extended term. Such rent
determination shall not take into account improvements to


                                       36

the Premises made by Tenant or on Tenant's behalf at Tenant's sole expense, or
any Additional Improvements. If the higher appraisal of rent is not more than
one hundred five percent (105%) of the lower appraisal of rent, the average of
their appraised values shall be adopted by the parties. If the higher appraisal
is greater than one hundred five percent (105%) of the lower, then the two
appraisers shall within five (5) days of the initial appraisal determinations
appoint a third appraiser who shall make his determination within thirty (30)
days of his appointment, and the two closest in dollar terms of the three
offered rent determinations shall be averaged and adopted by the parties as the
monthly Base Rent during the upcoming extended term. In no event shall the Base
Rent determined by the appraisers be less than the then existing monthly Base
Rent. In the event the Base Rent so determined is higher than Tenant's highest
previously negotiated offer Tenant may elect, by written notice to Landlord
within three (3) days after receipt of the appraisers' determination, to
terminate this Lease effective as of the date this Lease would have expired but
for Tenant's earlier exercise of said option to extend the term, in which event
Tenant's earlier exercise of said option shall be deemed rescinded. Tenant shall
pay all costs of the appraisers in the event Tenant so elects to rescind its
exercise and terminates this Lease.

            29.3  RENTAL ADJUSTMENTS DURING EXTENDED TERM. The Base Rent during
the first, or if it is the case, the second or third extended term, determined
pursuant to Paragraph 29.2 of this Lease shall be adjusted annually throughout
such term to reflect any increase in the cost of living during the extended term
in the manner specified in Paragraph 3.2 with respect to the initial term. For
the purposes of this paragraph, all other definitions set forth in Paragraph 3.2
of this Lease shall apply, except that the term "base" shall mean the last
published Index in effect on the first day of the extended term in question.

      30.   PARKING. Tenant shall have the nonexclusive use of Tenant's Share of
the parking spaces in the Outside Areas as designated from time to time by
Landlord. Tenant shall not at any time park or permit the parking of Tenant's
trucks or other vehicles, or trucks or other vehicles of others, adjacent or
loading areas so as to interfere in any way with the use of such areas, nor
shall Tenant at any time park or permit the parking of Tenant's vehicles or
trucks, or the vehicles or trucks of Tenant's suppliers or others, in any
portion of the Outside Areas not designated by Landlord for such use by Tenant.
Tenant shall not park or permit to be parked any inoperative vehicles or
equipment on any portion of the Outside Areas.

      31.   REASONABLE CONSENT. Whenever any party's approval or consent is
required by this Lease, such consent or approval shall not be unreasonably
withheld or delayed.


                                       37

      32.   Cure Period.

            32.1  CURE BY LANDLORD. Landlord shall not be deemed to be in
default in the performance of any obligation required to be performed by it
hereunder unless and until it has failed to perform such obligation within the
period of time specifically provided herein, or if no period of time has been
provided, then within thirty (30) days after receipt of written notice by Tenant
to Landlord specifying wherein Landlord has failed to perform such obligation;
provided, however, that if the nature of Landlord's obligation is such that more
than thirty (30) days are reasonably required for its performance, then Landlord
shall not be deemed to be in default if it shall commence such performance
within such thirty (30) day period and thereafter diligently prosecute the same
to completion. It is understood that, for purposes of Paragraphs 9.1, 13 and
10.1, the term "omissions", as used therein, shall mean only omissions by
Landlord which if not cured with the time period permitted in this Paragraph 32
would result in a default of Landlord hereunder.

            32.2  CURE BY TENANT. In the event Landlord is deemed in default
with respect to its obligation to repair and maintain the roof of the Building
as provided elsewhere in this Lease, Tenant shall be entitled, after written
notice to such effect to Landlord, to make such repairs and shall have the right
to demand reimbursement by Landlord of the cost thereof, with interest thereon
at the rate of ten percent (10%) or the highest rate allowed by law, whichever
is less, from the date of the expenditure until repaid. In addition, in the
event a condition exists with respect to any portion of the Premises which
Landlord is required to repair under the Lease, and such condition is the direct
and immediate cause of an emergency situation which presents a clear and present
threat to the physical safety of persons on or about the Premises or of property
of Tenant or its agents, employees, or contractors located on or about the
Premises, then subject to the following, Tenant shall be entitled to make such
repairs as are reasonably necessary to reduce such threat to a reasonably
acceptable level. As soon as Tenant becomes aware of any such condition, it
shall make every reasonable effort to contact Landlord by telephone or in person
and inform Landlord of the condition; if upon so informing Landlord of the
condition, Landlord elects to correct the condition as soon as Tenant would
otherwise be able to correct the condition, then Tenant shall have no right to
correct the condition and Landlord shall correct the same. If Tenant is unable
to contact Landlord after exhausting reasonable efforts to do so, or does in
fact contact Landlord but Landlord does not elect to correct the condition as
quickly as Tenant is able to correct the condition, then Tenant shall be
entitled to make such repairs and shall have the right to demand reimbursement
by Landlord of the cost thereof, with interest thereon at the rate of ten
percent (10%) or

                                       38

the highest rate allowed by law, whichever is less, from the date of the
expenditure until repaid.

      33.   MORTGAGEE PROTECTION. In the event of any default on the part of
Landlord, Tenant will give notice by registered or certified mail to any
beneficiary of a deed or trust or mortgagee of a mortgage, encumbering the
Premises whose address shall have been furnished to Tenant, and before
exercising any remedy of Tenant to terminate this Lease, shall allow such
beneficiary or mortgagee a reasonable opportunity to cure the default, including
time to obtain possession of the Premises by power or sale or judicial
foreclosure, if such should prove necessary to effect a cure.

      34.   General Provisions.

            34.1  ENTIRE AGREEMENT. This instrument including the Exhibits
attached hereto contains all of the agreements and conditions made between the
parties hereto and may not be modified orally or in any manner other than by an

            34.2  TIME. Time is of the essence with respect to the performance
of each and every provision of this Lease in which time of performance is a
factor. All references to days contained in this Lease shall be deemed to mean
calendar days, unless otherwise specifically stated.

            34.3  CAPTIONS. The captions and headings of the numbered paragraphs

interpretation of any part hereof.

            34.4  CALIFORNIA LAW. This Lease shall be construed and interpreted
in accordance with the laws of the State of California. The language in all
parts of this Lease shall in all cases be construed as a whole according to its
fair meaning and not strictly for or against either Landlord or Tenant, and
without regard to which party prepared this Lease.

            34.5  PARTIAL INVALIDITY. If any provision of this Lease is held by
a court of competent jurisdiction to be invalid, void, or unenforceable, the
remainder of the provisions hereof shall nonetheless continue in full force and
effect and shall in no way be affected, impaired, or invalidated thereby.


                                       39

            34.6  NO WARRANTIES. Any agreements, warranties or representations
not expressly contained herein shall not bind either Landlord or Tenant, and
Landlord and Tenant expressly waive all claims for damages by reason of any
statement, representation, warranty, promise or agreement, if any, not expressly
contained in this Lease.

            34.7  SUCCESSORS AND ASSIGNS. The covenants and conditions herein
contained, subject to the provisions as to assignment, shall inure to the
benefit of and bind the heirs, executors, administrators, assigns, and any other
person or entity succeeding lawfully, and pursuant to the provisions of this
Lease, to the rights or obligations of the respective parties hereto.

            34.8  RULES AND REGULATIONS. Landlord may from time to time
promulgate reasonable rules and regulations for the use, safety, care and
cleanliness of the Premises and the Project. Such rules and regulations shall be
binding upon Tenant upon delivery of a copy thereof to Tenant, and Tenant shall
abide by all such rules and regulations. If there is a conflict between such
rules and regulations and any of the provisions of this Lease, the provisions of
this Lease shall prevail.

            34.9  AUTHORITY. The individuals signing this Lease hereby represent
and warrant that they have all necessary power and authority to execute and
deliver this Lease on behalf of Landlord and Tenant, respectively.

            34.10 MEMORANDUM OF LEASE. This Lease shall not be recorded.
Concurrently with execution of this Lease, the parties shall execute and
acknowledge a short form memorandum of this Lease in the form attached hereto as
EXHIBIT "F". Simultaneously with execution of such memorandum, Tenant shall
execute and deliver to Landlord for recordation upon the expiration or sooner
termination of this Lease, a quitclaim deed to the Premises, in recordable form,
designating Landlord as transferee. Any recordation by Landlord of such
quitclaim deed prior to expiration or sooner termination of this Lease shall be
deemed a default by Landlord hereunder. In the event Landlord later transfers
its interest in the Premises prior to expiration or sooner termination of this
Lease, such quitclaim deed shall be relinquished to Tenant and Tenant shall
simultaneously execute and deliver to Landlord a new quitclaim deed designating
Landlord's successor in interest as the transferee, which quitclaim deed shall
again only be recorded upon expiration or sooner termination of this Lease.

            34.11 REASONABLE EXPENDITURES. An expenditure by a party, for which
such party shall demand reimbursement from the other party, shall be limited to
the fair market value of the goods and services involved, shall be reasonably
incurred, and


                                       40

shall be substantiated by documentary evidence available for inspection and
review by the other party or its representative during normal business hours.

            34.12 AMENDMENTS TO ACCOMMODATE LENDERS. Tenant agrees to execute
any amendments required by a lender to enable Landlord to obtain replacement
permanent financing so long as Tenant's rights and obligations hereunder are not
materially adversely affected and provided such amendments are of the type
normally required by such lender for similar loans. Tenant shall not have any
obligations under any such agreements unless and until Tenant signs the same.

            34.13 MERGER. The voluntary or other surrender of this Lease, or a
mutual cancellation thereof, shall not work an automatic merger, but shall, at
the sole option of Landlord, either terminate all or any existing subleases or
subtenancies, or operate as an assignment to Landlord of any or all of such
subleases or subtenancies.

            34.14 FORCE MAJEURE. Any prevention of or delay in the performance
by a party hereto of its obligations under this Lease caused by inclement
weather, labor disputes (including strikes and lockouts), inability to obtain
materials or reasonable substitutes therefor, governmental restrictions,
regulations, controls, action or inaction, civil commotion, fire or other causes
beyond the reasonable control of the party obligated to perform (except
financial inability), shall excuse the performance by such party of its
obligations hereunder (except the obligation of Tenant to pay rent and other
sums hereunder) for a period of one day for each such day of delay.

2.    Should Lender become the owner of the Property, or should the Property be
sold by reason of foreclosure, or other proceedings brought to enforce the Deed
of Trust which encumbers the Property, or should the Property be transferred by
deed in lieu of foreclosure, or should any portion of the Property be sold under

furniture, equipment or other personal property at any time placed or installed
in the Premises, or the Additional Improvements (as defined in the Lease).
