================================================================================
PRINCIPAL AMOUNT: $3,000,000.00   INITIAL RATE: 8.250%
DATE OF NOTICE:   APRIL 27, 1996

PROMISE  TO PAY.  CERPROBE  CORPORATION  ('Borrower')  promises  to pay to First
Interstate Bank of Arizona,  N. A. ('Lender'),  or order, in lawful money of the
United States of America, the principal amount of Three Million & 00/100 Dollars
($3,000,000.00) or so much as may be outstanding,  together with interest on the
unpaid  outstanding  principal  balance  of  each  advance.  Interest  shall  be
calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid  interest on April 28, 1997. In addition,  Borrower will
pay regular monthly payments of accrued unpaid interest  beginning May 31, 1996,
and all subsequent interest payments are due on the last day of each month after
that. Interest on this Note is computed on a 365/360 simple interest basis; that
is, by  applying  the ratio of the annual  interest  rate of a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual number
of days the  principal  balance  is  outstanding.  Borrower  will pay  Lender at
Lender's  address  shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will be
applied in any order at Lender's sole discretion.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is the First  Interstate Bank of
Arizona,  N.A. Prime Rate,  which is an index Lender announces from time to time
for pricing certain loans (the 'Index'). The Index is not necessarily the lowest
rate charged by Lender on its loans and is set by Lender in its sole discretion.
If the Index  becomes  unavailable  during  the term of this  loan,  Lender  may
designate a substitute index after notifying Borrower. Lender will tell Borrower
the current Index rate upon Borrower's request. Borrower understands that

Lender may make loans based on other  rates as well.  The  interest  rate change
will not occur  more  often  than each day.  The Index  currently  is 8.250% per
annum. The interest rate to be applied to the unpaid  principal  balance of this
Note will be at a rate  equal to the  Index,  resulting  in an  initial  rate of
8.250% per annum.  NOTICE: Under no circumstances will the interest rate on this
Note be more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early  payments will not,  unless agreed to by Lender in
writing,  relieve Borrower of Borrower's obligation to continue to make payments
of accrued unpaid interest.

DEFAULT.  Borrower  will be in  default  if any of the  following  happens:  (a)
Borrower  fails to make any payment when due.  (b)  Borrower  breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this note or
any agreement  related to this Note, or in any other  agreement or loan Borrower
has with Lender. (c)Borrower defaults under any loan, extent of credit, security
agreement,  purchase or sales agreement, or any other agreement, in favor of any
other creditor or person that may materially  affect any of Borrower's  property
or Borrower's ability to repay this Note or perform Borrower's obligations under
this Note or any of the Related  Documents.  (d) Any representation or statement
made or  furnished  to Lender by  Borrower or on  Borrower's  behalf is false or
misleading in any material  respect either now or at the time made or furnished.
(e)  Borrower  becomes  insolvent,  a  receiver  is  appointed  for any  part of
Borrower's property,  Borrower makes an assignment for the benefit of creditors,
or any proceeding is commenced  either by Borrower or against Borrower under any
bankruptcy or insolvency  laws. (f) Any creditor tries to take any of Borrower's
property on or in which Lender has a lien or security interest.  This includes a
garnishment  of any of Borrower's  accounts  with Lender.  (g) Any of the events
described in this default  section  occurs with respect to any guarantor of this
Note. (h) A material adverse change occurs in Borrower's financial condition, or
Lender  believes the prospect of payment of performance of the  indebtedness  is
impaired. (I) Lender in good faith deems itself insecure.

LENDER'S  RIGHTS.  Upon default,  Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest  immediately  due,  without
notice, and then Borrower will pay that amount. Upon default,  including failure
to pay upon final maturity,  Lender, at its option, may also, if permitted under
applicable  law,  increase  the  variable  interest  rate on this  Note to 4.000
percentage  points over the Index. The interest rate will not exceed the maximum
rate  permitted by applicable  law.  Lender may hire or pay someone else to help
collect this Note if Borrower does not pay. Borrower also will pay Lender






that amount. This includes, subject to any limits under applicable law, Lender's
attorneys'  fees and Lender's legal expenses  whether or not there is a lawsuit,
including  attorney's  fees  and  legal  expenses  for  bankruptcy   proceedings

prohibited  by  applicable  law,  Borrower  also  will pay any court  costs,  in

         state, and local laws, regulations,  and ordinances,  including without
         limitation  those laws,  regulations  and ordinances  described  above.
         Borrower  authorizes Lender and its agents to enter upon the properties
         to make such  inspections  and tests as Lender may deem  appropriate to
         determine  compliance  of  the  properties  with  this  section  of the
         Agreement.  Any  inspections  or  tests  made  by  lender  shall  be at
         Borrower's  expense  and for  Lender's  purposes  only and shall not be
         construed  to create any  responsibility  or  liability  on the part of
         Lender to  Borrower or to any other  person.  The  representations  and
         warranties  contained  herein are based on Borrower's  due diligence in
         investigating  the properties for hazardous waste.  Borrower hereby (a)
         releases and waives any future claims  against  Lender for indemnity or
         contribution in the event Borrower  becomes liable for cleanup or other
         costs  under  any such  laws,  and (b)  agrees  to  indemnify  and hold
         harmless  Lender  against  any and  all  claims,  losses,  liabilities,
         damages,   penalties,   and  expenses  which  Lender  may  directly  or
         indirectly sustain or suffer resulting from a breach of this section of
         the Agreement or as a consequence of any use, generation,  manufacture,
         storage,  disposal,  release or threatened  release  occurring prior to
         Borrower's ownership or interest in the properties,  whether or not the
         same was or should have been known to Borrower.  The provisions of this
         section of the Agreement,  including the obligation to indemnify, shall
         survive  the  payment  of  the  Indebtedness  and  the  termination  or
         expiration  of this  Agreement  and shall not be  affected  by Lender's
         acquisition  of any  interest  in any of  the  properties,  whether  by
         foreclosure or otherwise.

         Litigation   and   Claims.   No   litigation,   claim,   investigation,
         administrative proceeding or similar action (including those for unpaid
         taxes) against Borrower is pending or






         threatened,  and no other  event  has  occurred  which  may  materially
         adversely affect Borrower's  financial  condition or properties,  other

         disclosed to and approved by Lender in writing.

         of Borrower that are or were required to be filed, have been filed, and
         all taxes, assessments and other governmental charges have been paid in
         full,  except those  presently  being or to be contested by Borrower in
         good faith in the ordinary  course of business  and for which  adequate
         reserves have been provided.

         Lien  Priority.  Unless  otherwise  previously  disclosed  to Lender in
         writing,  Borrower  has  not  entered  into  or  granted  any  Security
         Agreements,  or  permitted  the filing or  attachment  of any  Security
         Interests on or affecting any of the Collateral  directly or indirectly
         securing  repayment of Borrower's Loan and Note, that would be prior or
         that may in any way be  superior  to Lender's  Security  Interests  and
         rights in and to such Collateral.

         Binding  Effect.  This  Agreement,  the Note,  all Security  Agreements
         directly or indirectly  securing  repayment of Borrower's Loan and Note

         legally enforceable in accordance with their respective terms.

         for business or commercial related purposes.

         Employee Benefit Plans. Each employee benefit plan as to which Borrower

         satisfactory to Lender determine, as applicable,  the actual cash value

         lawful claims that,  if unpaid,  might become a lien or charge upon any
         of  Borrower's  properties,   income,  or  profits.  Provided  however,
         Borrower will not be required to pay and discharge any such assessment,
         tax,  charge,  levy,  lien or claim so long as (a) the  legality of the
         same shall be contested in good faith by appropriate  proceedings,  and
         (b) Borrower shall have established on its books adequate reserves with
         respect to such contested assessment, tax, charge, levy, lien, or claim

         the  assessments,  taxes,  charges,  levies,  liens and claims and will

         records and  computer  software  programs  for the  generation  of such
         records) in the possession of a third party, Borrower,  upon request of
         Lender,  shall  notify such party to permit  Lender free access to such
         records at all  reasonable  times and to provide  Lender with copies of

accounts. Borrower authorizes Lender, to the extent permitted by applicable law,
to charge or setoff all sums owing on the Indebtedness  against any and all such
accounts,  and, at Lender's option, to administratively freeze all such accounts
to allow Lender to protect  Lender's  charge and setoff rights  provided on this

         failure  of  Borrower  to comply  with or to  perform  any other  term,
         obligation,  covenant or  condition  contained  in any other  agreement

         Default in Favor of Third Parties.  Should Borrower or any






         Grantor  default  under  any  loan,   extension  of  credit,   security
         agreement,  purchase or sales  agreement,  or any other  agreement,  in
         favor of any other creditor or person that may materially affect any of
         Borrower's property or Borrower's or any Grantor's ability to repay the
         Loans or perform their respective  obligations  under this Agreement or
         any of the Related Documents.

         furnished  to Lender by or on behalf of Borrower  or any Grantor  under
         this  Agreement or the Related  Documents is false or misleading in any
         material  respect at the time made or  furnished,  or becomes  false or
         misleading at any time thereafter.

         Defective  Collateralization.  This  Agreement  or any  of the  Related
         Documents ceases to be in full force and effect  (including  failure of
         any  Security  Agreement  to  create  a valid  and  perfected  Security
         Interest) at any time and for any reason.

         Borrower.

         Creditor or Forfeiture  Proceedings.  Commencement  of  foreclosure  or
         forfeiture  proceedings,  whether by  judicial  proceeding,  self-help,
         repossession  or any other  method,  by any creditor of  Borrower,  any
         creditor  of  any  Grantor   against  any   collateral   securing   the
         Indebtedness,   or  by  any  governmental   agency.   This  includes  a
         garnishment,  attachment,  or levy on or of any of  Borrower's  deposit
         accounts with Lender.

         Events  Affecting  Guarantor.  Any of the preceding  events occurs with

         Insecurity.  Lender, in good faith, deems itself insecure.







EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where
otherwise provided in this Agreement or the Related  Documents,  all commitments
and  obligations of Lender under this Agreement or the Related  Documents or any
other  agreement  immediately  will terminate  (including any obligation to make
Loan  Advances or  disbursements),  and, at Lender's  option,  all  Indebtedness
immediately  will  become due and  payable,  all  without  notice of any kind to
Borrower,  except that in the case of an Event of Default of the type  described
in the 'Insolvency'  subsection above, such acceleration  shall be automatic and
not  optional.  In  addition,  Lender  shall have all the  rights  and  remedies
provided in the Related  Documents or available at law, in equity, or otherwise.
Except as may be  prohibited  by  applicable  law,  all of  Lender's  rights and
remedies  shall be cumulative and may be exercised  singularly or  concurrently.
Election by Lender to pursue any remedy  shall not exclude  pursuit of any other
remedy,  and an  election to make  expenditures  or to take action to perform an
obligation  of  Borrower or of any Grantor  shall not affect  Lender's  right to
declare a default and to exercise its rights and remedies.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions
are a part of this Agreement:

         Amendments.  This  Agreement,  together  with  any  Related  Documents,
         constitutes the entire understanding and agreement of the parties as to
         the matters set forth in this Agreement.  No alteration of or amendment

         or amendment.

         Applicable  Law.  This  Agreement  has been  delivered  to  Lender  and
         accepted  by  Lender in the State of  Arizona.  If there is a  lawsuit,
         Borrower agrees upon Lender's  request to submit to the jurisdiction of
         the courts of  Maricopa  County,  the State of  Arizona  Subject to the
         provisions on  arbritration,  this  Agreement  shall be governed by and
         construed  in  accordance  with  the  laws  of the  State  of  Arizona.
         Arbitration.

         Binding Arbitration. Upon the demand of any party ('Party/Parties'), to
         a Document (as defined  below),  whether made before the institution of
         any  judicial  proceeding  or not more than 60 days after  service of a
         complaint,  third party  complaint,  cross-claim or counterclaim or any
         answer  thereto or any  amendment to any of the above,  any Dispute (As
         defined  below) shall be resolved by binding  arbitration in accordance
         with the terms of this Arbitration  Program.  A 'Dispute' shall include
         any action,  dispute, claim or controversy of any kind, whether founded
         in contract,  tort, statutory or common law, equity, or otherwise,  now
         existing or hereafter arising between any of the Parties arising out






         of,  pertinent  to or in  connection  with any  agreement,  document or
         instrument to which this Arbitration Program is attached or in which it
         appears or is  referenced  or any  related  agreements,  documents,  or
         instruments  ('Documents').  Any Party  who fails to submit to  binding
         arbitration  following a lawful  demand by another Party shall bear all
         costs and expenses,  including reasonable  attorney's fees,  (including
         those  incurred  in any  trial,  bankruptcy  proceeding  or on  appeal)
         incurred by the other Party in obtaining a stay of any pending judicial
         proceeding and compelling arbitration of any Dispute. The parties agree
         that any agreement,  document or instrument which includes, attaches to
         or  incorporates  this  Arbitration  Program  represents a  transaction
         involving commerce as that term is used in the Federal Arbitration Act,
         ('FAA') Title 9 United States Code. THE PARTIES UNDERSTAND THAT BY THIS
         AGREEMENT  THEY HAVE DECIDED THAT THEIR  DISPUTES  SHALL BE RESOLVED BY
         BINDING   ARBITRATION  RATHER  THAN  IN  COURT,  AND  ONCE  DECIDED  BY
         ARBITRATION NO DISPUTE CAN LATER BE BROUGHT, FILED OR PURSUED IN COURT.

         Governing Rules.  Arbitrations  conducted  pursuant to this Arbitration
         Program shall be administered by the American  Arbitration  Association
         ('AAA'), or other mutually agreeable administrator ('Administrator') in
         accordance  with  the  terms  of  this  Arbitration   Program  and  the
         Commercial Arbitration Rules of the AAA. Proceedings hereunder shall be
         governed by the provisions of the Federal  Arbitration  Act (Title 9 of
         the United States Code). The  arbitrator(s)  shall resolve all Disputes
         in accordance  with the  applicable  substantive  law designated in the
         Documents. Judgment upon any award rendered hereunder may be entered in
         any court having  jurisdiction;  provided,  however that nothing herein
         shall be  construed  to be a waiver by any party  that is a bank of the
         protections afforded pursuant to 12 U.S.C. 91 or any similar applicable
         state law.

         Preservation  of  Remedies.  No  provision  of, nor the exercise of any
         rights  under,  this  arbitration  clause  shall limit the right of any
         Party  to:  (a)  foreclose   against  any  real  or  personal  property
         collateral or other security, or obtain a personal or deficiency award;
         (b) exercise  self- help remedies  (including  repossession  and setoff
         rights);  or  (c)obtain  provisional  or  ancillary  remedies  such  as
         injunctive relief, sequestration, attachment, replevin, garnishment, or
         the  appointment of a receiver from a court having  jurisdiction.  Such
         rights can be exercised at any time except to the extent such action is
         contrary to a final award or  decision in any  arbitration  proceeding.
         The  institution  and maintenance of an action as described above shall
         not constitute a waiver of the right of any Party to submit the Dispute
         to arbitration, nor render inapplicable






         the  compulsory  arbitration  provisions  hereof.  Any claim or Dispute
         related to exercise of any  self-help,  auxiliary or other rights under
         this paragraph shall be a Dispute hereunder.

         Arbitrator  Powers and  Qualifications;  Awards.  The Parties  agree to
         select a neutral 'qualified' arbitrator or a panel of three 'qualified'
         arbitrators  to resolve  any  Dispute  hereunder.  'Qualified'  means a
         practicing attorney, with not less than 10 years practice in commercial
         law,  licensed to practice in the state of the  applicable  substantive
         law  designated  in the  Documents.  A Dispute  in which the  claims or
         amounts in controversy do not exceed  $1,000,000.00 shall be decided by
         a single arbitrator. A single arbitrator shall have authority to render
         an award up to but not to exceed $1,000,000.00 including all damages of
         any  kind  whatsoever,  costs,  fees,  attorneys'  fees  and  expenses.
         Submission  to a single  arbitrator  shall be a waiver of all  Parties'
         claims to recover more than  $1,000,000.00.  A Dispute involving claims
         or amounts in controversy exceeding $1,000,000.00 shall be decided by a
         majority vote of a panel of three qualified arbitrators. An arbitration
         panel shall be composed of one arbitrator who would be qualified to sit
         as a  single  arbitrator  hereunder,  one who has at  least  ten  years
         experience  in  commercial  lending  and one who has at least ten years
         experience  in the  Borrower's  industry.  The  arbitrator(s)  shall be
         empowered to, at the written  request of any Party in any Dispute,  (a)
         to  consolidate  in a single  proceeding any multiple party claims that
         are   substantially   identical  or  based  upon  the  same  underlying
         transaction;  (b) to consolidate any claims and Disputes  between other
         Parties  which  arise out of or relate to the  subject  matter  hereof,
         including all claims by or against borrowers,  guarantors, sureties and
         or owners of  collateral;  and (c)to  administer  multiple  arbitration
         claims as class actions in accordance with Rule 23 of the Federal Rules
         of  Civil  Procedure.   In  any   consolidated   proceeding  the  first
         arbitrator(s) selected in any proceeding shall conduct the consolidated
         proceeding  unless  disqualified  due  to  conflict  of  interest.  The
         arbitrator(s)  shall be empowered to resolve any dispute  regarding the
         terms  of  this  arbitration  clause,  including  questions  about  the
         arbitrability  of any  Dispute,  but  shall  have no power to change or
         alter the terms of this  Arbitration  Program.  The prevailing Party in
         any Dispute shall be entitled to recover its reasonable attorneys' fees
         in any arbitration, and the arbitrator(s) shall have the power to award
         such fees. The award of the arbitrator(s) shall be in writing and shall
         set forth the factual and legal basis for the award.

         Miscellaneous.  All  statues of  limitation  applicable  to any Dispute
         shall apply to any proceeding in accordance






         with this arbitration  clause. The Parties agree, to the maximum extent
         practicable,  to take any action  necessary to conclude an  arbitration
         hereunder  within  180  days  of  the  filing  of a  Dispute  with  the
         Administrator. The arbitrator(s) shall be empowered to impose sanctions
         for any Party's failure to proceed within the times established herein.
         Arbitrations  shall  be  conducted  in  the  state  of  the  applicable
         substantive  law  designated in the  Documents.  The provisions of this
         Arbitration  program  shall  survive  any  termination,  amendment,  or
         expiration  hereof or of the  Documents  unless the  Parties  otherwise
         expressly agree in writing.  Each Party agrees to keep all Disputes and
         arbitration  proceedings strictly confidential,  except for disclosures
         of  information  required  in the  ordinary  course of  business of the
         Parties  or as  required  by  applicable  law  or  regulation.  If  any
         provision of this Arbitration Program is declared invalid by any court,
         the remaining provisions shall not be affected thereby and shall remain
         fully enforceable.

         Caption   Headings.   Caption   headings  in  this  Agreement  are  for
         convenience purposes only and are not to be used to interpret or define
         the provisions of this Agreement.

         Multiple  Parties;  Corporate  Authority.  All  obligations of Borrower
         under this Agreement shall be joint and several,  and all references to
         Borrower  shall mean each and every  Borrower.  This means that each of
         the Borrowers  signing below is responsible for all obligations in this
         Agreement.

         Consent to Loan Participation. Borrower agrees and consents to Lender's
         sale or transfer,  whether now or later,  of one or more  participation
         interests in the Loans to one or more  purchasers,  whether  related or
         unrelated  to  Lender.  Lender  may  provide,  without  any  limitation
         whatsoever,  to any one or more purchasers,  potential purchasers,  any
         information  or knowledge  Lender may have about  Borrower or about any
         other  matter  relating to the Loan,  and  Borrower  hereby  waives any
         rights to privacy it may have with  respect to such  matters.  Borrower
         additionally  waives  any and  all  notices  of  sale of  participation
         interests,   as  well  as  all  notices  of  any   repurchase  of  such
         participation  interests.  Borrower also agrees that the  purchasers of
         any such  participation  interests  will be  considered as the absolute
         owners of such  interests  in the  Loans  and will have all the  rights
         granted under the participation  agreement or agreements  governing the
         sale of such  participation  interests.  Borrower  further  waives  all
         rights of offset or counterclaim  that it may have now or later against
         Lender or against any  purchaser of such a  participation  interest and
         unconditionally agrees that either Lender or such purchaser may enforce
         Borrower's obligation under the Loans irrespective of the failure or






         insolvency of any holder of any interest in the Loans. Borrower further
         agrees  that the  purchaser  of any such  participation  interests  may
         enforce its interests  irrespective  of any personal claims or defenses
         that Borrower may have against Lender.

         Borrower  Information.  Borrower consents to the release of information
         on or about Borrower by Lender in accordance with any court order,  law
         or regulation and in response to credit inquiries concerning Borrower.

         Non-Liability of Lender.  The relationship  between Borrower and Lender
         is a debtor and creditor  relationship and not fiduciary in nature, nor
         is the  relationship  to be construed as creating  any  partnership  or
         joint venture  between Lender and Borrower.  Borrower is exercising its
         own  judgment  with respect to  Borrower's  business.  All  information
         supplied to Lender is for Lender's  protection  only and no other party
         is entitled to rely on such information. There is no duty for Lender to
         review,  inspect,  supervise,  or inform  Borrower  of any matter  with
         respect to Borrower's business.  Lender and Borrower intend that Lender
         may reasonably rely on all information  supplied by Borrower to Lender,
         together with all  representations  and warranties given by Borrower to
         Lender,  without  investigation  or confirmation by Lender and that any
         investigation  or failure to  investigate  will not  diminish  Lender's
         right to so rely.

         Notice of Lender's  Breach.  Borrower  must notify Lender in writing of
         any breach of this Agreement or the Related Documents by Lender and any
         other claim,  cause of action or offset  against  Lender  within thirty
         (30) days after the  occurrence  of such breach or after the accrual of
         such claim, cause of action or offset. Borrower waives any claim, cause
         of action or offset for which  notice is not given in  accordance  with
         this paragraph.  Lender is entitled to rely on any failure to give such
         notice.

         Borrower  indemnification.  Borrower  shall  indemnify  and hold Lender
         harmless from and against all claims, costs, expenses, losses, damages,
         and  liabilities  of any kind,  including but not limited to attorneys'
         fees and  expenses,  arising  out of any matter  relating  directly  or
         indirectly  to  the  Indebtedness,   whether  resulting  from  internal
         disputes between Borrower and any Guarantor,  or whether  involving any
         third parties,  or out of any other matter  whatsoever  related to this
         Agreement  or  the  Related  Documents,  but  excluding  any  claim  or
         liability which arises as a direct result of Lender's gross  negligence
         or willful misconduct.  This indemnity shall survive full repayment and
         satisfaction of the Indebtedness and termination of this Agreement.







         Counterparts.  This Agreement may be executed in multiple counterparts,
         each of which, when so executed,  shall be deemed an original,  but all
         such  counterparts,  taken together,  shall constitute one and the same
         Agreement.

         Costs and Expenses.  Borrower agrees to pay upon demand all of Lender's
         allocated  costs of in-house  counsel and expenses,  including  without
         limitation   attorney's   fees,   incurred  in   connection   with  the
         preparation,  execution,  enforcement,  modification  and collection of
         this  Agreement or in  connection  with the Loans made pursuant to this
         Agreement. Lender may pay someone else to help collect the Loans and to
         enforce  this  Agreement,  and  Borrower  will  pay that  amount.  This
         includes,   subject  to  any  limits  under  applicable  law,  Lender's
         attorneys' fees and Lender's legal expenses,  whether or not there is a
         lawsuit,   including   attorneys'   fees  for  bankruptcy   proceedings
         (including   efforts  to  modify  or  vacate  any  automatic   stay  or
         injunction),  appeals,  and any  anticipated  post-judgment  collection
         services.  Borrower  also will pay any court costs,  in addition to all
         other sums provided by law.

         Notices. All notices required to be given under this Agreement shall be
         given in writing, may be sent by telefacsimilie, and shall be effective
         when actually delivered or when deposited with a nationally  recognized

         notices  under this  Agreement by giving formal  written  notice to the
         other parties,  specifying  that the purpose of the notice is to change
         the party's  address.  To the extent  permitted by  applicable  law, if
         there is more than one Borrower, notice to any Borrower will constitute
         notice to all Borrowers.  For notice purposes,  Borrower agrees to keep
         Lender informed at all times of Borrower's current address(es).

         Severability.  If a court of competent jurisdiction finds any provision
         of this  Agreement to be invalid or  unenforceable  as to any person or
         circumstance,  such finding shall not render that provision  invalid or
         unenforceable  as to any other persons or  circumstances.  If feasible,
         any such  offending  provision  shall be  deemed to be  modified  to be
         within  the  limits of  enforceability  or  validity;  however,  if the
         offending provision cannot be so modified, it shall be stricken and all
         other  provisions of this  Agreement in all other respects shall remain
         valid and enforceable.

         Subsidiaries  and Affiliates of Borrower.  To the extent the context of
         any provisions of this Agreement makes it






         appropriate, including without limitation any representation,  warranty
         or  covenant,  the word  'Borrower'  as used herein  shall  include all
         subsidiaries and affiliates of Borrower.  Notwithstanding the foregoing
         however,  under no  circumstances  shall this Agreement be construed to
         require Lender to make any Loan or other financial accommodation to any
         subsidiary or affiliate of Borrower.

         Successors and Assigns. All covenants and agreements contained by or on
         behalf of  Borrower  shall bind its  successors  and  assigns and shall
         inure to the benefit of Lender,  its successors  and assigns.  Borrower
         shall not,  however,  have the right to assign  its  rights  under this
         Agreement or any interest therein, without the prior written consent of
         Lender.

         Survival.  All  warranties,  representations,  and  covenants  made  by
         Borrower in this agreement or in any  certificate  or other  instrument
         delivered  by  Borrower  to  Lender  under  this  agreement   shall  be
         considered  to have been  relied  upon by Lender and will  survive  the
         making of the Loan and  delivery  to Lender of the  Related  Documents,
         regardless of any investigation made by Lender or on Lender's behalf.

Time  Is of the  Essence.  Time is of the  essence  in the  performance  of this
Agreement.

Waiver.  Lender  shall  not be deemed  to have  waived  any  rights  under  this
Agreement unless such waiver is given in writing and signed by Lender.  No delay
or omission  on the part of Lender in  exercising  any right shall  operate as a
waiver of such right or any other  right.  A waiver by Lender of a provision  of
this  Agreement  shall not  prejudice or  constitute a waiver of Lender's  right
otherwise to demand strict compliance with that provision or any other provision
of this Agreement.  No prior waiver by Lender, nor any course of dealing between
Lender and  Borrower,  or between  Lender and any  Grantor,  shall  constitute a
waiver of any of  Lender's  rights or of any  obligations  of Borrower or of any
Grantor  as to any  future  transactions.  Whenever  the  consent  of  Lender is
required  under this  Agreement,  the  granting of such consent by Lender in any
instance shall not constitute  continuing consent in subsequent  instances where
such  consent  is  required,  and in all cases  such  consent  may be granted or
withheld in the sole discretion of Lender.

                           Phoenix, AZ 85072-3456


This  Agreement  is entered  into on April 27,  1996,  by and  between  CERPROBE
CORPORATION  ('Borrower') and First Interstate Bank of Arizona,  N.A. ('Lender')
and supplements the Promissory Note of Borrower dated April 27, 1996, ('Note').

In addition to the rate of interest  provided for in the Note, the interest rate
option(s) set out below  (individually and  collectively,  if more than one, the
'Alternate  Rate')  shall be  available  to  Borrower on the terms set forth for
certain portions of the amounts outstanding under the Note ('Loans').  Each Loan
to which an Alternate  Rate applies shall be referred to as an  'Alternate  Rate
Advance'.

 1.      As used herein, the following terms shall have the meaning
         set forth:

         LENDER BUSINESS DAY

         'Lender  Business  Day'  means a day other than  Saturday  or Sunday on
         which  banks in Phoenix  are open for  business  and Lender can conduct
         business in appropriate markets for the Alternative Rates Offered.

         LIBOR PROVISIONS

         'LIBOR' means a per annum interest rate equal to two point  twenty-five
         percent (2.25%) per annum in excess of the prevailing  London interbank
         offered rate at which dollar deposits in the approximate  amount of the
         relevant  LIBOR  Advance for the  relevant  LIBOR Period are offered to
         Lender  at  11:00  a.m.  London  time on the day  which is two (2) Bank
         Business Days prior to the  commencement of the relevant LIBOR Interest
         Period.

         'LIBOR  Advance'  means each Loan which bears  interest at LIBOR.  Each
         LIBOR Advance  shall be in an amount of Two Hundred and Fifty  Thousand
         Dollars ($250,000).







         'LIBOR  Notice'  means an  irrevocable  notice  by  Borrower  to Lender
         received by Lender at least three (3) Lender Business Days prior to the
         Lender  Business  Day  selected as the date upon which such  Eurodollar
         Advance shall be made stating that Borrower elects to pay interest on a
         Loan at LIBOR,  and  specifying  the amount of the LIBOR  Advance,  the
         LIBOR Period for such LIBOR Advance,  and the Lender  Business Day upon
         which the LIBOR Period is to begin. Such notice shall be in writing or,
         if given  orally or  telephonically,  shall be  confirmed  to Lender in
         writing within one (1) business day of such oral or telephonic  notice.
         Lender's  records shall control an difference  between any LIBOR Notice
         and/or confirmation thereof.

         'LIBOR  Period' means an interest  period of one (1), two (2), or three
         (3) months as selected,  and commencing on a date specified by Borrower
         in a LIBOR  Notice and agreed to by Lender.  If any LIBOR  Period would
         otherwise  expire on a day that is not a Lender Business Day, the LIBOR
         Period shall expire on the next succeeding Lender Business Day.

 2.      Provided that there is no default under this Agreement or the Note, nor
         the  existence  of any event  which,  with the  giving of notice or the
         passage of time,  or both,  would  constitute  a default  hereunder  or
         thereunder, and, provided further, that Lender has not demanded payment
         in full of the  obligations  outstanding  under the Note,  Borrower may
         elect with the  consent of Lender  obtained  at the time of the request
         for each  Alternate  Rate  Advance,  to have a portion of the Loan bear
         interest at any Alternate Rate offered in accordance with the terms and
         conditions set forth herein.

 3.      Borrower  shall elect to use the Alternate Rate for such portion of the
         Loan by  providing  to Lender the  appropriate  Alternate  Rate notice.
         Failure  of  Lender to  receive  a  Alternate  Rate  notice or  written
         confirmation of such notice shall not affect  Borrower's  obligation to
         repay a Alternate Rate advance and the interest  thereon.  Lender shall
         not be obligated to offer any Alternate Rate if it reasonably  believes
         such Alternate Rate or applicable  funding is not available to it or is
         illegal. No Alternate Rate Period shall extend beyond the maturity date
         of the Note.

 4.      Upon  expiration of each Alternate Rate interest  period,  the interest
         rate  applicable to the Alternate Rate Advance shall  thereafter be the
         interest rate provided for in the Note.

 5.      Unless demand is made by Lender for payment in full, no Alternate  Rate
         Advance may be prepaid in whole or in part prior to the last day of its
         applicable  Alternate  Rate interest  period  without the prior written
         consent of Lender. If any prepayment is made for whatever reason,






         Borrower  agrees to pay upon  demand  any loss or  reduction  in return
         calculated  by Lender in  liquidating  or  reemploying  deposits in the
         market  from  which the  interest  rate  applicable  to such funds were
         derived.

 6.      As to any matter  arising from,  related to or in  connection  With any
         Alternate  Rate Advance,  Lender's  records and  calculations  shall be
         conclusive, absent manifest error.

 7.      Interest  shall be computed and charged  monthly and on the last day of
         the  applicable  Alternate  Rate  interest  period  on the basis of the
         actual  number of days elapsed over a year of three hundred sixty (360)
         days.

 8.      Borrower  understands  that an Alternate Rate notice is irrevocable and
         that  Borrower is therefore  'at-risk' to the extent that  Borrower and
         Lender  will not  know the rate  Borrower  must pay  until  Lender  has
         purchased its funds.  Any quote  provided by Lender prior to the actual
         purchase  is only an  estimate  of the  probable  rate and shall not be
         binding as to actual rate.

 9.      In  addition to all other sums due under the terms of the Note and this
         Agreement,  Borrower shall pay to Lender as additional  interest,  such
         amounts, if any, as will compensate Lender for any increase in the cost
         or reduction in the  profitability  to Lender of making or  maintaining
         any Alternate Rate Advance or any other portion of the Loan (determined
         by Lender's use of any reasonable method for the allocation,  averaging
         and  attribution  of the aggregate of such  increases or reductions) by
         reason of a change in or establishment  of or Lender's  compliance with
         (a) any reserve,  special deposit or other requirement and with respect
         to assets of,  deposits with or for the account of, or credit  extended
         by Lender which are imposed on or deemed applicable by Lender under any
         law,  treaty,   rule,   regulation   (including,   without  limitation,
         Regulation D of the Board of Governors of the Federal Reserve  System),
         (b) any interpretation thereof by any governmental, fiscal, monetary or
         other  authority  charged  with the  administration  thereof  or having
         jurisdiction  over  Lender,  (c)any  requirement  imposed  by any  such
         authority,  whether  or not  having  the  force  of  law,  or  (d)  any
         requirement,   request,  directive,  standard  or  guideline  regarding
         capital  adequacy  (whether  or not  having  the  force of  law).  Such
         additional amounts shall be payable to Lender on demand.

10.      All payments of principal of and interest on any Alternate Rate Advance
         shall be made  without  deduction  of any  present  and  future  taxes,
         levies,  imposts,  deductions,  charges or withholdings,  which amounts
         shall be paid by Borrower. Borrower will pay the amounts necessary such
         that the gross amount of the principal and interest






         received by Lender is not less than that required under this Agreement.
         All  stamp  and   documentary   taxes   shall  be  paid  by   Borrower.
         Notwithstanding the foregoing, if Lender pays such taxes, Borrower will
         reimburse Lender upon demand for the amount paid.

11.      Any default under this Agreement  shall  constitute a default under the
         provisions of the Note and no delay or omission by Lender in exercising
         any right shall operate as a waiver of such right.

12.      All terms and  conditions  of the Note  shall  remain in full force and
         effect,  including the prime rate based  pricing  applicable to (a) any
         Loan not  subject  to an  Alternate  Rate or other  rate  agreed  to in
         writing by Borrower an Lender and (b) the Loan after notice for payment
         in full has been given Borrower and Lender.

13.      This Agreement shall be governed by and construed in
         accordance with the laws applicable to the Note.
