  (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.

            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.

       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
   11
  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
   12
  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

                                       7

   13
  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

   14
  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

   15
  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

   16

            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
   17

  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.

   18
            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
   19

  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

   20
  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

   21
  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

   22
  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
   23
  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
   24
  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
   25

            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
   26

  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

   27

  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
   28

            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
   29
  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
   30
  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

   31
  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
   32

  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
   33

            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

   34
  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
   35

  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
   36

                 (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
   37

                      (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
   38

                      (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
   39

  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

  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

  fiscal year, and the two (2) immediately prior fiscal years (if available),
  all prepared in accordance with generally accepted accounting principles

  financial statements in connection with an intended disposition or
  refinancing of the Building.

  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:

       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
   41

  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
   42

  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
   43
  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
   44

       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
   45

  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

  respective successors in interest.  Any executed copy of this Lease shall be
  deemed an original for all purposes.

            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 of this Lease are inserted solely for the convenience of the
  parties hereto, and are not a part of this Lease and shall have no effect
  upon the construction or 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
   46


            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
   47
  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.

Official Records of Santa Clara County, California in favor of Lender, payable
upon the terms and conditions described therein;

C.  The parties desire to acknowledge that the loan secured by the Deed of

D.  The parties hereto desire to assure Tenant's possession and control of the
Property under this Lease upon the terms and conditions therein contained.

NOW THEREFORE, for and in consideration of the mutual covenants and promises

   54
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 a trustee's sale, the Lease shall continue in full force and effect as a
direct lease between the then owner of the Property covered by the Deed of
Trust and Tenant, upon, and subject to, all of the terms, covenants and 
conditions of the Lease for the balance of the term thereof remaining, 
including any extension therein provided.  Tenant does hereby agree to attorn
to Lender or to any such owner as its landlord, and Lender hereby agrees that
it will accept such attornment.

3.  Notwithstanding any other provision of this Agreement, Lender shall not be
(a) liable for any previously accrued default of any landlord under the Lease
(including Landlord) as of the date Lender forecloses or otherwise takes title
to the Property; (b) subject to any offsets or defenses which have accrued
prior to the date of foreclosure, unless Tenant shall have delivered to lender
written notice of the default which gave rise to such offset or defense and
permitted Lender the same right to cure such default as is permitted Landlord
under the Lease; (c) bound by any rent or other sums that Tenant may have paid
under the Lease more than one month in advance; (d) bound by any amendment or
modification of the Lease hereafter made without Lender's prior written
consent; (e) responsible for the return of any security deposit delivered to
Landlord under the Lease and not subsequently received by Lender.

4.  If Lender sends written notice to Tenant to direct its rent payments under
the Lease to Lender instead of Landlord, then Tenant agrees to follow the
instructions set forth in such written instructions and deliver rent payments
to Lender; however, Landlord and Lender agree that Tenant shall be credited
under the Lease for any rent payments sent to lender pursuant to such written
notice.

5.  All notices which may or are required to be sent under this Agreement shall
be in writing and shall be sent by first class certified U.S. mail, postage
prepaid, return receipt requested, and sent to the party at the address
appearing below its signature hereof or such other address as any party shall
hereafter inform the other party by written notice given as set forth above.
All notices delivered as set forth above shall be deemed effective five (5)
days after the posted date of deposit in the U.S. mail.

6.  The Deed of Trust shall not cover or encumber and shall not be construed as
subjecting in any manner to the lien thereof any of Tenant's trade fixtures,
furniture, equipment or other personal property at any time placed or installed
in the Premises, or the Additional Improvements (as defined in the Lease).

7.  Landlord and Tenant each acknowledges that the other is not in default or
breach of any of its obligations under the Lease as of the date hereof.
