                            SECOND AMENDMENT TO LEASE
                    2975 STENDER WAY, SANTA CLARA, CALIFORNIA

              current  term of this  Lease.  If  Tenant  fails to  provide  such
              notice, Tenant shall have no further or additional right to extend
              or renew the term of this Lease.

         (2)  The Base Rent in effect at the expiration of the then current term
              of this Lease shall be  increased to reflect  ninety-five  percent
              (95%) of the current fair market  rental for  comparable  space in
              other  similar  buildings in the same rental market as of the date
              the renewal term is to commence,  taking into account the specific
              provisions  of this Lease  which  will  remain  constant,  and the
              Building amenities,  location,  identity, quality, age, condition,
              term of lease, tenant improvements,  services provided,  and other
              pertinent items.

         (3)  Landlord  shall advise Tenant of the new Base Rent for the Premise
              for the applicable renewal term based on Landlord's  determination
              of fair market rental value, no later than fifteen (15) days after
              receipt of notice of Tenant's exercise of its option to renew.

         (4)  Landlord and Tenant shall  negotiate in good faith to agree on the
              fair market rental value of the Premises and terms and  conditions
              for the renewal  term.  If Tenant and Landlord are unable to agree
              on a mutually  acceptable  rental rate for the renewal term within
              thirty  (30) days  after  notification  by  Landlord  to Tenant of
              Landlord's  determination  of the new Base  Rent  for the  renewal
              term, but in any event no later than the date which is ninety (90)
              days prior to the expiration of the then current term,  then on or
              before such date Landlord and Tenant shall each appoint a licensed
              real estate  broker with at least ten (10)  year's  experience  in
              leasing R &  D/industrial  space in the area in which the Building
              is  located  to act as  arbitrators.  The two (2)  arbitrators  so
              appointed  shall  determine  the fair market  rental value for the
              Premises  for the  applicable  renewal  term  based  on the  above
              criteria  and each shall submit his or her  determination  of such
              fair market rental value to Landlord and Tenant in writing, within
              sixty (60) days after their appointment.

              If the two (2)  arbitrators so appointed  cannot agree on the fair
              market  rental value for the  applicable  renewal term within such
              60-day period,  the two (2) arbitrators shall within five (5) days
              thereafter appoint a third arbitrator who shall be a licensed real
              estate broker with at lest ten (10) year's experience in leasing R
              & D/industrial space in the area in which the Building is located.
              The third  arbitrator so appointed shall  independently  determine
              the fair market rental value for the Premises for the renewal term
              within thirty (30) days after  appointment,  by selecting from the
              proposals  submitted by each of the first two  arbitrators the one
              that   most   closely    approximates   the   third   arbitrator's
              determination of such

                            SECOND AMENDMENT TO LEASE
                    2975 STENDER WAY, SANTA CLARA, CALIFORNIA

              fair market rental value. The third arbitrator shall have no right
              to adopt a  compromise  or middle  ground or any  modification  of
              either of the  proposals  submitted by the first two  arbitrators.
              The  proposal  chosen  by the  third  arbitrator  as most  closely
              approximating  the third  arbitrator's  determination  of the fair
              market rental value shall constitute the decision and award of the
              arbitrators and shall be final and binding on the parties.

              Each  party  shall  pay the fees and  expenses  of the  arbitrator
              appointed  by such  party  and  one-half  (1/2)  of the  fees  and
              expenses of the third arbitrator.

              If either  party fails to appoint an  arbitrator,  or if either of
              the first two  arbitrators  fails to submit his or her proposal of
              fair market  rental value to the other party,  in each case within
              the time periods set forth  above,  then the decision of the other
              party's arbitrator shall be considered final and binding.

              In the event the third  arbitrator  fails to present a fair market
              rental value within such 30-day period,  then by mutual consent of
              the Landlord and Tenant:

                  (a)      the time period will be extended, or

                  (b)      If  either  Landlord  or Tenant do not wish to extend
                           the  time  period,  a  fourth   arbitrator  shall  be
                           selected  by  the  first  two  arbitrators  and a new
                           thirty (30) day period shall begin.

         (5)  Notwithstanding   anything  to  the  contrary  contained  in  this
              Paragraph, in no event shall the Base Rent for the renewal term be
              less  than the Rent in  effect  in the  last  year of this  second
              Amendment ($1.65 per square foot per month). In addition, Landlord
              shall  have  no  obligation  to  provide  or pay  for  any  tenant
              improvements or brokerage commissions during any renewal term.

         (6)  Tenant's  right  to  exercise  the  option  to  renew  under  this
              Paragraph  shall be conditioned  upon Tenant  occupying the entire
              Premises  and  the  same  not  being  occupied  by  any  assignee,
              subtenant  or licensee  other than Tenant or its  affiliate at the
              time of  exercise  of the option and  commencement  of the renewal
              term.  Tenant's exercise of the option to renew shall constitute a
              representation  by  Tenant  to  Landlord  that  as of the  date of
              exercise of the option and the  commencement  of the renewal term,
              Tenant does not intend to seek to assign this Lease in whole or in
              part, or sublet all or any portion of the Premises.

                            SECOND AMENDMENT TO LEASE
                    2975 STENDER WAY, SANTA CLARA, CALIFORNIA

         (7)  Any exercise by Tenant of any option to renew under this Paragraph
              shall be irrevocable.  If requested by Landlord,  Tenant agrees to
              execute a lease  amendment or, at Landlord's  option,  the parties
              will  negotiate  and  agree  to a  new  lease  for  the  Building,
              reflecting  the  foregoing  terms  and  conditions,  prior  to the
              commencement  of the  renewal  term.  The option to renew  granted
              under this Paragraph is/are not  transferable;  the parties hereto
              acknowledge  and agree that they  intend that each option to renew
              this  Lease  under  this  Paragraph  shall  be  "personal"  to the
              specific  Tenant named in this Lease and that in no event will any
              assignee or sublessee  have any rights to exercise  such option to
              renew.

RENTAL  VALUE  INSURANCE:  Tenant shall obtain and keep in force a policy in the
name of Lessor with loss payable to Lessor and any Lender,  insuring the loss of
the full rent for one (1) year.

Except as expressly modified above, all terms and conditions of the Lease remain
in full force and effect and are hereby ratified and confirmed.

         IN WITTNESS  WHEREOF,  the parties hereto have entered into this second
Amendment as of the date first written above.
