                                      LEASE

This Lease is made as of the 1st day of May, 1996 by and between MEDTRONIC,
INC., a Minnesota corporation ("Landlord") and MICRO COMPONENT TECHNOLOGY, INC.,
a Minnesota corporation ("Tenant").

1.    Premises. Tenant shall relocate its operations to that space located on
      the second floor of the Building, as described in Exhibit A, consisting of
      approximately 59,969 square feet of usable space with a common square foot
      factor of 34.538, for a total rentable area of 80,676 square feet of the
      Building located at 3840 Victoria Street in Shoreview, Minnesota. Shared
      common areas shall include a visitor lobby, employee entry, cafeteria,
      food preparation space, mechanical space, dock space, major egress
      hallways, restrooms and stairwells. The entire cost of Tenant relocation
      shall be borne by Tenant.

2.    Term. The term of the Lease shall be twelve (12) months, commencing on May
      1, 1996 or upon the date of closing, whichever is later, and ending on
      April 30, 1997.

3.    Rent.

      (a) Rent. Tenant shall pay as monthly Rent for the Premises the sum of
      Sixty-Six Thousand Five Hundred Fifty-Seven Dollars and Ninety Cents
      ($66,557.90). Rent shall include the cost of utilities (gas, electric,
      water and sewer) subject to the usage requirements of Paragraph 9 hereof,
      taxes (real estate), insurance, building maintenance and housekeeping, as
      described in Exhibit B annexed hereto.

      (b) Late Charges. Tenant hereby acknowledges that late payments by Tenant
      to Landlord of rent and other sums due hereunder will cause Landlord to
      incur costs not contemplated by this Lease, the exact amount of which will
      be extremely difficult to ascertain. Such costs include, but are not
      limited to utility, processing and accounting charges, and late charges
      which may be imposed upon Landlord. Accordingly, if any installment of
      rent or other sum due from Tenant shall not be received by Landlord within
      fifteen (15) days after such amount shall be due, then, without any
      requirement for notice to Tenant, Tenant shall pay to Landlord a late
      charge equal to five percent (5%) of such overdue amount. The parties
      hereby agree that such late charge represents a fair and reasonable
      estimate of the costs Landlord will incur by reason of late payments by
      Tenant. Acceptance of such late charge by Landlord shall in no event
      constitute a waiver of Tenant's Default or Breach with respect to such
      overdue amount, nor prevent Landlord from exercising any of the other
      rights and remedies granted hereunder. In the event that a late charge is
      payable hereunder, whether or not collected, for three (3) consecutive
      installments of Rent, then notwithstanding Paragraph 4 or any other
      provision of this Lease to the contrary, Rent shall, at Landlord's option,
      become due and payable quarterly in advance.

4.    Relocation. Tenant will relocate from its current occupancy on the first
      and third  floors of the  Building to the second  floor in  accordance  
      with the Schedule in Exhibit C.  Landlord  shall be entitled  to  
      dedicated  space on the second floor for dock access as shown 
      on Exhibit B.

5.    Leasehold Improvements.

      (a) Tenant Obligations. As part of its relocation, Tenant shall finish the
      Premises in accordance with current building codes. Landlord is under no
      obligation to make any structural or other alterations, decoration,
      additions or improvements in or to the Premises. Tenant is taking the
      premises "AS IS" and Landlord shall not be obligated to do any work in the
      Premises.

      (b) Tenant Restrictions. Tenant shall not make any material alterations,
      additions or improvements in or to the Premises, or make any changes in
      locks on doors, or add, disturb or in any way change any floor covering,
      wall covering, fixtures, plumbing or wiring [other than as described in
      Section 5(a)] without first obtaining the written consent of Landlord,
      which consent shall not be unreasonably withheld or delayed. Tenant shall
      deliver to Landlord full and complete plans and specifications for any
      such alteration, addition or improvement. Tenant shall not add any
      curtains, draperies or other hangings on or beside any windows that are
      visible from outside the Building without Landlord's permission which
      shall not be unreasonably withheld or delayed.

      (c) Lien Protection. Tenant shall pay when due all claims for labor or
      materials furnished or alleged to have been furnished to or for Tenant at
      or for use on the Premises, which claims are or may be secured by any
      mechanic's or materialmen's lien against the Premises or any interest
      therein. Tenant shall give Landlord not less than ten (10) days' notice
      prior to the commencement of any work in, on or about the Premises, and
      Landlord shall have the right to post notices of non-responsibility in or
      on the Premises as provided by law. If Tenant shall, in good faith,
      contest the validity of any such lien, claim or demand, then Tenant shall,
      at its sole expense, defend and protect itself, Landlord and the Premises
      against the same and shall pay and satisfy any such adverse judgment that
      may be rendered thereon before the enforcement thereof against the
      Landlord or the Premises. If Landlord shall require, Tenant shall furnish
      to Landlord a surety bond satisfactory to Landlord in an amount equal to
      one and one-half times the amount of such contested lien claim or demand,
      indemnifying Landlord against liability for the same, as required by law
      for the holding of the Premises free from the effect of such lien or
      claim. In addition, Landlord may require Tenant to pay Landlord's
      attorneys' fees and costs in participating in such action if Landlord
      shall decide it is to its best interest to do so.

6.    Use.

      (a) Tenant Use of Premises. Tenant will use and occupy the Premises solely
      for general office and light manufacturing purposes. Tenant will not use
      or occupy the Premises for any unlawful purpose, and will comply with all
      present and future laws, ordinances, regulations and orders of all
      governmental units having jurisdiction over the Premises. Tenant shall not
      cause or permit any unusual noise, odors or nuisance in or about the
      Premises. Landlord disclaims any warranty that the Premises are suitable
      for Tenant's use.

      (b) Rules and Regulations. Tenant shall use the Premises and the common
      areas of the Building in accordance with the terms of this Lease and such
      additional rules and regulations as may from time to time be agreed to by
      Tenant and the Landlord for the general safety, comfort and convenience of
      the owners, occupants and tenants of the Building, and Tenant shall use
      its best efforts to cause Tenant's customers, employees and invitees to
      abide by such rules and regulations. Landlord shall in no event be
      responsible to Tenant for enforcement of such rules and regulations
      against other tenants.

      (c) Indemnification by Tenant. Tenant agrees to indemnify, defend and hold
      Landlord and its partners, officers and employees and property manager
      harmless from and against any claim, loss or expense arising out of
      injury, death or property loss or damage occurring in the Premises, except
      only to the extent caused by the negligent act or intentional misconduct
      of Landlord, its officers, employees or property manager.
      
      (d) Indemnification by Landlord. Landlord agrees to indemnify, defend and
      hold Tenant and its partners, officers and employees harmless from and
      against any claim, loss or expense arising out of injury, death or
      property loss or damage occurring in the common areas of the Building,
      except to the extent caused by the negligent act or intentional misconduct
      of Tenant or its partners, officers or employees.

      (e) Covenant of Quiet Enjoyment. Landlord covenants that it has the right
      to make this Lease for the term aforesaid and covenants that if Tenant
      shall pay the rent and perform all of the covenants, terms and conditions
      of this Lease to be performed by Tenant, Tenant shall, during the Term
      hereby created, freely, peaceably and quietly occupy and enjoy possession
      of the Premises. Tenant acknowledges, however, that Landlord will be
      remodeling spaces on the first and third floors beginning on or about the
      effective date of this Lease. Landlord will use reasonable efforts to
      minimize disruption to Tenant and shall in no case disrupt Tenant's
      manufacturing operations during normal business hours.

      (f) Employment of Receptionist. Landlord and Tenant may each at its own
      expense employ a receptionist at the main entrance of the Building during
      the term of this Lease.

7.    Services by Landlord.

      (a) Cleaning Services. Landlord Will provide cleaning services on or about
      the Premises and common areas pursuant to Exhibit B annexed hereto.

      (b) Maintenance Responsibility. Landlord shall keep and maintain the
      structural walls and foundation of the Premises in good and safe condition
      (except to the extent repairs, maintenance or replacement are made
      necessary by the abuse, misuse or negligence of Tenant, its employees,
      agents or contractors, in which case Tenant shall be responsible for
      required repairs, maintenance or replacements). Landlord shall maintain
      HVAC, electrical and mechanical systems for the Building and provide
      exterior Building maintenance and grounds keeping.

      (c) Food Services. Landlord will contract, effective August 1, 1996, with
      an in-house vending/food service organization to provide food service in
      the existing cafeteria. Tenant employees shall have the opportunity to use
      the food service. Landlord shall not subsidize any food service costs. The
      level of food service will be provided at the discretion of Landlord.

      (d) Security. Landlord will provide on-site security twenty-four (24)
      hours per day, seven (7) days per week.

8.    Service and Utilities.

      (a) Heating and Air Conditioning. Landlord will furnish reasonable heat
      and air conditioning during normal business hours and during the usual and
      appropriate seasons.

      (b) Utilities and Services. Landlord will furnish electricity for standard
      building lighting, manufacturing and office use, water, elevator service
      and toilet facilities during normal business hours.

      (c) Liability/Indemnification. Landlord shall not be liable to Tenant, its
      agents, employees, representatives, customers or invitees for any
      inconvenience, loss or damage resulting from any temporary failure or lack
      of such services beyond Landlord's control, and Tenant shall indemnify
      Landlord and hold Landlord harmless from any claim or damage because of
      such inconvenience, loss or damage.

      (d) Tenant Use/Responsibility. Tenant shall use heat, air conditioning,
      water and electricity with due care, and such use shall be consistent with
      Tenant's use for the previous twelve months and, without qualifying the
      foregoing, Tenant shall not neglect or misuse water fixtures, electric
      lights and heating and air conditioning apparatus.

      (e) Services by Landlord. Landlord will provide services customary to
      first-class office buildings in the Greater Minneapolis area, including
      without limitation, electricity for lighting, manufacturing, office
      machines, water and sewer, security system, and mechanical, cooling,
      heating and ventilation at such times as Landlord normally furnishes this
      service to other tenants of the Building, but in no event less than normal
      business hours, and at such temperatures and in such amounts as are
      reasonably standard for firstclass office buildings in the Greater
      Minneapolis area. All services including elevator, Building access through
      the security system, water and parking, but not including the cooling,
      heating and ventilation systems, shall be available at all times. Normal
      business hours shall be from 7:00 a.m. to 10:00 p.m. on weekdays, and 8:00
      a.m. to noon on Saturdays, excluding legal holidays. Landlord shall not be
      liable for any loss or damage caused by or resulting from any variation,
      interruption or failure of such services unless due to Landlord's gross
      negligence, and no temporary interruption or failure of such services
      incident to the making of repairs, alterations or improvements or due to
      accident or strike conditions shall be deemed as an eviction of Tenant or
      relieve Tenant from any of Tenant's obligations hereunder. For those
      services within Landlord's reasonable control, Landlord will correct any
      interruption of services as soon as practicable. Landlord shall provide
      mechanical, cooling, heating and ventilation at times other than normal
      business hours upon Tenant's request and reasonable notice to Landlord. If
      Tenant has special mechanical, cooling, heating, ventilation, electrical
      or other requirements beyond its current needs, then the cost of
      furnishing, installing, operating and maintaining the equipment and
      appurtenances, including separate meters if requested by Landlord, to
      satisfy these requirements shall be borne by Tenant, with Tenant either
      paying directly to the utility if separately metered or paying to Landlord
      as an expense in addition to Rent the reasonable cost of providing such
      additional services.

9.    Insurance.

      (a) Tenant Obligations. Tenant agrees to carry in full force and effect
      the following insurance:

                  (i) "All risk" property insurance covering the full
            replacement value of all of Tenant's leasehold improvements, trade
            fixtures and personal property within the Premises. Tenant shall be
            named as loss payee under all such policies.

                  (ii) Commercial general liability insurance, providing
            coverage on an "occurrence" rather than a "claims made" basis, which
            policy shall include coverage for Bodily Injury, Property Damage,
            Personal Injury, Contractual Liability (applying to this Lease), and
            Independent Contractors. Tenant shall maintain a combined policy
            limit of at least $2,000,000 applying to Bodily Injury, Property
            Damage and Personal Injury, which limit may be satisfied by Tenant's
            basic policy, or by the basic policy in combination with umbrella or
            excess policies so long as the coverage is at least as broad as that
            required herein. Landlord shall be named as additional insured under
            all such policies.

      (b) Evidence of Insurance. Tenant shall deliver to Landlord, at least five
      (5) days prior to the effective date of this Lease, evidence that the
      insurance required by this Lease is in full force and effect. At least ten
      (10) days prior to expiration of any such coverage, Tenant shall deliver
      evidence that the coverage in question will be renewed or replaced upon
      expiration. Such evidence of insurance shall contain sufficient
      information to enable Landlord to determine whether Tenant's insurance
      complies with the requirements of this Lease. Upon request, Tenant shall
      also furnish insurer certified copies of all pertinent policies. All
      policies used to provide the coverage required by this Lease shall (i) be
      endorsed to require the insurer to provide at least ten (10) days' notice
      to Landlord prior to cancellation or non-renewal and (ii) be issued by
      financially sound companies.

      (c) Landlord Obligations. Landlord agrees to purchase or self insure, and
      carry in full force and effect, the following insurance:

                  (i) "All risk" property insurance coverage on the Building,
            exclusive of Tenant's leasehold improvements, in such amount as
            Landlord deems prudent.

                  (ii) Comprehensive commercial public liability insurance
            covering the Building, in a combined single limit amount of not less
            than $2,000,000, and written on an "occurrence" basis.

      (d) Waiver and Indemnity. Notwithstanding anything apparently to the
      contrary in this Lease, Landlord and Tenant hereby release one another and
      their respective partners, officers and employees and property manager
      from any and all liability (to the other or anyone claiming through or
      under them by way of subrogation or otherwise) for any loss or damage
      covered by property insurance or coverable by a customary policy of
      insurance, even if such loss or damage shall have been caused by the fault
      or negligence of the other party, or anyone for whom such party may be
      responsible.

10.   Fire or Other Casualty. If the Premises or the Building shall be
      damaged by fire or other cause, Landlord shall at its option either (a)
      undertake to restore such damage with all due diligence or (b) in the 
      event the Premises or the Building is damaged by fire or other cause to 
      such extent that damage cannot, in Landlord's sole judgment, be 
      economically repaired within ninety (90) days after the date of such 
      damage (taking into account the time necessary to effectuate a 
      satisfactory settlement with any insurance company and using normal 
      construction methods without overtime or other premium), terminate this 
      Lease, by notice given to Tenant within fifteen (15) days after the date 
      of the damage. Any termination hereunder by reason of damage to the 
      Premises shall be effective as of the date of the damage. Any termination
      by reason of damage to the Building but not the Premises shall be 
      effective as of the date notice is given. If Landlord elects to restore, 
      Landlord shall not be obligated to restore any improvements in the 
      Premises which were not owned and constructed by Landlord. This Lease 
      shall, unless terminated by Landlord pursuant to this Paragraph 11, remain
      in full force and effect following such damage, and, in the case of damage
      to the Premises, the Rent prorated to the extent that the Premises are 
      rendered untenantable, shall be equitably abated until such repairs are 
      completed, provided, however, that if Tenant does not restore its 
      leasehold improvements and trade fixtures with due diligence, abatement 
      shall cease as of the date restoration could have been completed using due
      diligence.

11.  Condemnation.  If the whole or any  substantial  part of the  Premises
     shall be taken or condemned or purchased  under threat of condemnation by 
     any governmental authority, then the Term of this Lease shall cease and 
     terminate effective upon the condemnation or purchase.

12.   Assignment/Subletting. The Tenant shall not (i) assign, convey, mortgage,
      pledge, encumber or otherwise transfer (whether voluntarily or otherwise)
      this Lease or any interest under it; (ii) allow any transfer thereof or
      any lien upon Tenant's interest by operation of law; (iii) sublet the
      Leased premises or any part thereof; or (iv) permit the use of occupancy
      of the Leased Premises or any part thereof by anyone other than the
      Tenant.

13.   Signs. Tenant shall not place or maintain any sign, advertisement or
      notice on any part of the outside of the Building. Landlord shall have the
      right to remove or relocate current signage on the Building in its
      discretion. Tenant shall be permitted to maintain the foundation sign
      currently located on the Premises and one sign near the main entrance to
      the Premises.

14.   No Right to Holdover. Tenant has no right to retain possession of the
      Premises or any part thereof beyond the expiration or earlier termination
      of this Lease. In the event that Tenant holds over in violation of this
      Paragraph 15, then the Rent payable from and after the time of the
      expiration or earlier termination of this Lease shall be increased to two
      hundred percent (200%) of the Rent applicable during the month immediately
      preceding such expiration or earlier termination. Nothing contained herein
      shall be construed as a consent by Landlord to any holding over by Tenant.

15.   Surrender/Restoration. Tenant shall surrender the Premises by the end of
      the last day of the Lease term or any earlier termination date, clean
      and free of debris and in good operating order, condition and state of
      repair, ordinary wear and tear excepted. Ordinary wear and tear shall
      not include any damage or deterioration that would have been prevented
      by Tenant performing all of its obligations under this Lease. Tenant
      shall own and remove all fixtures, equipment and leasehold
      improvements on the Premises. The obligation of Tenant shall include
      the repair of any damage occasioned by the installation, maintenance
      or removal of Tenant's Trade Fixtures, furnishings, equipment and
      Tenant Owned Alterations and Utility Installations. Tenant's Trade
      Fixtures shall remain the property of Tenant and shall be removed by
      Tenant subject to its obligation to repair and restore the Premises
      per this Lease.

16.   Hazardous Waste.

      (a) Tenant Use Restrictions. Tenant shall not install, use, generate,
      store or dispose of in or about the Premises any hazardous substance,
      toxic chemical, pollutant or other material regulated by the Comprehensive
      Environmental Response, Compensation and Liability Act of 1985 or the
      Minnesota Environmental Response and Liability Act or any similar law or
      regulation, including without limitation any material containing asbestos
      or PCB (collectively "Hazardous Materials") without Landlord's written
      approval of each Hazardous Material. Landlord shall not unreasonably
      withhold its approval of use by Tenant of immaterial quantities of
      Hazardous Materials customarily used in office/manufacturing business
      operations so long as Tenant uses such Hazardous Materials in accordance
      with applicable laws.

      (b) Duty to Inform Landlord. If Tenant knows, or has reasonable cause to
      believe, that a Hazardous Substance has come to be located in, on, under
      or about the Premises or the Building, other than as previously consented
      to by Landlord, Tenant shall immediately give Landlord written notice
      thereof, together with a copy of any statement, report, notice,
      registration, application, permit business plan, license, claim, action or
      proceeding given to, or received from, any governmental authority or
      private party concerning the presence, spill, release, discharge of, or
      exposure to, such Hazardous Substance, including but not limited to all
      such documents as may be involved in any Reportable Use involving the
      Premises. Tenant shall not cause or permit any Hazardous Substance to be
      spilled or released in, on, under or about the Premises (including,
      without limitation, through the plumbing or sanitary sewer system).

      (c) Indemnification. Tenant shall indemnify, protect, defend and hold
      Landlord, its agents, employees, lenders and ground lessor, if any, and
      the Premises, harmless from and against any and all damages, liabilities,
      judgments, costs, claims, liens, expenses, penalties, loss of permits and
      attorneys' and consultants' fees arising out of or involving any Hazardous
      Substance brought onto the Premises by or for Tenant or by anyone under
      Tenant's control. Tenant's obligations under this Paragraph 17 shall
      include, but not be limited to, the effects of any contamination or injury
      to person, property or the environment created thereof, or of any
      contamination therein involved, and shall survive the expiration or
      earlier termination of this Lease. No termination, cancellation or release
      agreement entered into by Landlord and Tenant shall release Tenant from
      its obligations under this Lease with respect to Hazardous Substances,
      unless specifically so agreed by Landlord in writing at the time of such
      agreement.

17.   Time of Essence. Time is of the essence with respect to the performance of
      all obligations to be performed or observed by the Parties under this
      Lease, including without limitation, Tenant's obligation to remove itself
      from the Premises upon termination of the Lease. Tenant acknowledges that
      Landlord will suffer significant and immeasurable damage should Tenant
      attempt to hold over at termination of this Lease.

18.   Relocation Progress. Landlord and Tenant acknowledge that Tenant will be
      relocating its business upon Termination of the Lease. In order to assure
      Landlord it is making sufficient progress toward its relocation plans,
      Tenant shall periodically, but not less than once per quarter, update
      Landlord on Tenant's progress towards ultimate relocation of its business
      upon termination.

19.   Default.

      (a) Definition. Any one of the following events shall constitute an Event
      of Default:

                  (i) Tenant shall fail to pay any monthly installment of Rent
            and such default shall continue for a period of fifteen (15) days
            after the due date therefor and written notice from Landlord;

                  (ii) Tenant shall violate or fail to perform any of the other
            conditions, covenants or agreements herein made by Tenant and such
            default shall continue for fifteen (15) days after written notice
            from Landlord; or

                  (iii) Tenant shall file or have filed against it any
            bankruptcy or other creditor's action which is not discharged within
            sixty (60) days, or make an assignment for the benefit of its
            credits.

      (b) Option to Terminate. If an Event of Default shall have occurred and be
      continuing, Landlord may at its sole option by written notice to Tenant
      terminate this Lease. Neither the passage of time after the occurrence of
      the Event of Default nor exercise by Landlord of any other remedy with
      regard to such Event of Default shall limit Landlord's rights under this
      Section 20.

      (c) Reimbursement of Attorneys' Fees. In addition to all other remedies,
      the prevailing party shall be entitled to reimbursement upon demand of all
      reasonable attorneys' fees incurred in connection with any Event of
      Default.

20.   Right to Enter. Landlord, its agents representatives shall constantly
      have pass keys to the Premises and may at all reasonable times during the
      day and night enter to view and inspect the Leased remises, or to clean 
      and maintain the same, or to make repairs, or to make such improvements or
      changes in the Leased Premises or the Building as Landlord may deem 
      proper. The right of entry reserved in the immediately preceding sentence
      shall not be deemed to impose any greater obligation on Landlord to clean,
      maintain, repair or change the Leased Premises than is specifically 
      provided in this Lease. The Landlord, its agents or representatives may at
      any time in case of emergency enter the Leased Premises and do such acts 
      as Landlord may deem proper in order to protect the Leased Premises, the 
      Building or any occupants of the Building. There shall be no diminution of
      rent or liability on the part of-Landlord by reason of inconvenience,

      payment without prejudice to Landlord's right to recover the balance of 
      such rent, to terminate this Lease, to Repossess the Premises or to pursue
      any other remedy provided by this Lease. No re-entry by Landlord, and no
