ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS.

Acquisition of Silicon Valley Test & Repair, Inc.

         On January 15, 1997 (the "Closing  Date"),  pursuant to an Agreement of
Merger  and Plan of  Reorganization  (the  "Agreement"),  by and among  Cerprobe
Corporation,  a Delaware corporation  ("Registrant"),  EMI Acquisition,  Inc., a
Delaware corporation and wholly-owned subsidiary of Registrant  ("Acquisition"),
Silicon  Valley Test & Repair,  Inc., a  California  corporation  ("SVTR"),  and
William  E.  Mayer  and  Carol  Mayer,  husband  and wife  (together,  "Mayer"),
Registrant  acquired  SVTR by  merger  of SVTR  with and into  Acquisition.  The
purchase  price  paid  by  Registrant  under  the  Agreement  consisted  of  (i)
$3,850,000 in cash,  subject to subsequent  adjustment based on SVTR's net worth
as of the  Closing  Date;  and  (ii)  300,000  shares  of the  common  stock  of
Registrant,  of which  125,000  shares have been placed in escrow as a source of
recourse for certain  indemnification claims Registrant and Acquisition may have
against Mayer pursuant to the Agreement.  Under the Agreement, Mayer may receive
up to an  additional  $500,000  in cash and up to  50,000  additional  shares of
Registrant's  common stock if Acquisition  achieves  certain sales and operating
profit targets for calendar year 1997.

         The  amount  and  nature  of the  purchase  price  were  determined  by
arms-length negotiations among the parties. The cash used in the transaction was
provided from the proceeds of a private placement of convertible preferred stock
issued by Registrant on January 18, 1996.

         In  connection   with  the   Agreement,   Registrant   entered  into  a
registration rights agreement with Mayer (the "Registration  Rights Agreement").
The Registration Rights Agreement grants Mayer certain "piggyback"  registration
rights.  Additionally,  Mr. Mayer  entered  into an  employment  agreement  with
Acquisition  (the  "Employment  Agreement")  that  expires on December 31, 1999.
Pursuant  to the  Employment  Agreement,  Mr.  Mayer  will  serve  initially  as
President  of  Acquisition  for six months and  thereafter  as Vice  President -
Strategic  Technology  Development  of  Acquisition  at a salary of $200,000 per
year. The Employment Agreement contains a covenant not to compete for the period
of his  employment  and for a  period  of 18  months  after  the  expiration  or
termination of the Employment Agreement.

         SVTR refurbishes and upgrades automatic wafer probing equipment used in
the semiconductor  industry.  Registrant intends for Acquisition to continue the
operations of SVTR.

         The  acquisition  will be  accounted  for  using the  purchase  method.
Accordingly,  the  purchase  price  will be  allocated  to assets  acquired  and
liabilities  assumed  based  upon  their  estimated  fair  values.   Preliminary
estimates of purchased  in-process  research and  development in connection with
the allocation is  approximately  $5,400,000.  The current state of the research
and development  products/processes is not yet at a technologically  feasible or
commercially  viable  stage.  Registrant  does not believe that the research and
development  products/processes  have any future alternative use because if they
are not finished  and brought to ultimate  product or process  completion,  they
have no other value.  Therefore,  consistent with generally accepted  accounting
principles,  Registrant  intends to take a one-time charge for the full value of
the purchased  in-process  research and  development in the first quarter ending
March 31, 1997.

                  THIS  AGREEMENT  OF MERGER  AND PLAN OF  REORGANIZATION  (this
"Agreement")  is made and entered  into this 15th day of January,  1997,  by and
among EMI ACQUISITION,  INC., a Delaware corporation  ("Acquisition"),  CERPROBE
CORPORATION, a Delaware corporation ("Cerprobe"),  SILICON VALLEY TEST & REPAIR,

                                    RECITALS
                                    --------

                  D. The  Boards of  Directors  of  Cerprobe,  Acquisition,  and

the terms and conditions contained in this Agreement.

                  1.2 The Surviving  Corporation.  Upon the  Effective  Time, as

with respect to the Merger are  thereafter  timely filed pursuant to the laws of
the State of California.

shall be in accordance with the Certificate of Merger for filing in the State of

insofar as the same may be continued by statute,  shall cease upon the Effective
Time.

Incorporation  of the  Surviving  Corporation  and the  Bylaws of the  Surviving
Corporation.

<PAGE>
                  2.3   Certificate  of   Incorporation.   The   Certificate  of
Incorporation  of Acquisition  as in existence  prior to the Merger shall be and
constitute the Certificate of Incorporation of the Surviving Corporation, except
that the name of the  Corporation  shall be changed to  "Silicon  Valley  Test &
Repair,  Inc." The  Certificate  of  Incorporation  may  thereafter  be altered,
amended or repealed in accordance with the General  Corporation Law of the State
of Delaware and the Bylaws of Acquisition.

                  2.4  Directors  and  Officers.  The  directors and officers of
Acquisition  prior to the Merger  shall be the  directors  and  officers  of the
Surviving Corporation, and each shall hold office until his successor is elected
and qualified or until his earlier  resignation or removal.  If on the Effective
Time of the Merger a vacancy  shall exist on the Board of Directors or in any of
the offices of the Surviving  Corporation as the same are specified above,  such

rights,  privileges,  powers,  licenses,  permits,  authorities,  franchises and
interests  of each of  Acquisition  and  Company,  both of a public and  private
nature, all of its and their property,  real,  personal and mixed, all debts due
on whatever  accounts  and  property  of every  description  and every  interest
therein  belonging  to  each  of  Acquisition  and  Company  or due to  each  of
Acquisition and Company shall thereafter be deemed to be the rights, privileges,
powers, licenses, permits,  authorities,  franchises and interests of, and shall
be  vested  in,  the  Surviving  Corporation  without  further  act or  deed  as
effectively  as they were  theretofore  vested in  Acquisition or Company as the

shall be  preserved  and  unimpaired  by the  Merger,  limited  to the  property
affected by such liens  immediately  prior to the Effective Time; and all debts,
liabilities  and duties of each of  Acquisition  and Company  shall  thenceforth
attach to the Surviving  Corporation and may be enforced  against it to the same
extent as if said debts,  liabilities and duties had been incurred or contracted
by  it.  Any  existing  claim,  action  or  proceeding  pending  by  or  against
Acquisition  or Company may be  prosecuted as if the Merger had not taken place,
or the Surviving  Corporation may be substituted in its place. Nothing herein is
intended to or shall extend or enlarge the lien of any  indenture,  agreement or
other instrument executed or assumed by either Acquisition or Company.

                  2.6  Service of  Process.  The  Surviving  Corporation  hereby

Surviving Corporation arising from the Merger,
                                        3
<PAGE>
including any suit or any other  proceeding to enforce the rights,  if any, of a
dissenting  shareholder  as determined in an appraisal  proceeding as allowed by

such adjustments as may be appropriate in giving effect to the Merger.


                                   ARTICLE III
                       Exchange and Cancellation of Stock
                       ----------------------------------

                  3.1  General.  The  manner  of  exchanging  the  shares of the
Company Stock for cash and shares of the Cerprobe Stock (as hereinafter defined)
to be issued  for and upon the  surrender  of all shares of the  Company  Stock,
shall be as hereinafter set forth in this Article III.

                  3.2 Exchange of the Company Stock and Issuance of the Cerprobe
Stock.

                           (a)   Exchange.   The   Company   Stock   issued  and
outstanding  at or  immediately  prior to the  Effective  Time  shall,  upon the
Effective  Time,  be  converted  into shares of the  Cerprobe  Stock and cash as
hereinafter provided.  Each outstanding certificate evidencing the Company Stock
not surrendered at the Effective Time to the Surviving Corporation,  which prior
to the Effective Time represented  shares of the Company Stock,  shall as of the
Effective  Time be deemed for all purposes  (other than the payment of dividends
or other  distributions,  if any,  in respect of  Cerprobe  Common  Stock) to be
cancelled and no longer  represent  shares of Company,  but instead to represent
the number of whole shares of the Cerprobe  Stock and cash into or for which the
shares of the Company Stock shall have been  converted  pursuant to this Section
3.2.

                           (b) Unsurrendered Certificates. Shares of the Company
Stock not surrendered upon the Effective Time are hereinafter referred to as the
"Unsurrendered  Certificates."  No  interest  shall be paid,  and no dividend or
other  distribution,  if any,  payable to the holders of shares of the  Cerprobe
Stock shall be paid, to the holders of Un- surrendered  Certificates;  provided,
however,  that upon surrender and exchange of such Un- surrendered  Certificates
there  shall  be  paid  to the  record  holders  of  the  stock  certificate  or
certificates issued in exchange for the Unsurrendered Certificates,  the amount,
without interest thereon,  of dividends and other  distributions,  if any, which
theretofore  but  subsequent to the Effective Time have been declared and become
payable with  respect to the number of whole  shares of the Cerprobe  Stock into
which the Unsurrendered Certificates shall have been converted.
                                        4
<PAGE>
                           (c) Cerprobe Stock and Cash. Upon the Effective Time,
all of the shares of the Company Stock shall be exchanged for:

                                     (i) a total of Three  Million Eight Hundred
Fifty Thousand Dollars  ($3,850,000)  (the "Proposed Cash Payment"),  subject to
adjustment as provided in Sections 3.2(d) and 3.2(e) hereof ; and

                                     (ii) a total  of  300,000  validly  issued,
fully paid, and nonassessable  shares of Cerprobe's Common Stock, par value $.05
per share (the "Cerprobe Stock").

                           (d) Closing  Adjustment to Proposed Cash Payment.  At
the Closing (as hereinafter  defined),  the parties shall in good faith estimate
the net worth of the Company as of the Closing (the "Estimated Net Worth").  The
Proposed  Cash Payment shall be reduced by $1.00 for every $1.00 or part thereof
by which the  Estimated  Net Worth of the Company is less than  $1,381,000,  and
shall be  increased  by $1.00  for  every  $1.00 or part  thereof  by which  the
Estimated  Net Worth of  Company is greater  than  $1,381,000,  to arrive at the
"Closing Cash Payment".

                           (e) Post-Closing Adjustment to Closing Cash Payment.

                                     (i)  Within  forty-five  (45)  days  of the
Closing,  Cerprobe shall generate a balance sheet for Company, without audit, as
of the Closing (the "Closing  Balance  Sheet"),  prepared on a basis  consistent
with the September  Balance Sheet (as hereinafter  defined).  Acquisition  shall
provide Mayer and his agents and  representatives  with full and complete access
to the books of account and records of Company then in its  possession,  and its
full  cooperation  to facilitate the  compilation  of information  necessary for
Mayer to determine  the net worth of Company as of the Closing.  Cerprobe  shall
provide Mayer with a copy of the Closing  Balance Sheet and a computation of the
net worth of  Company  as of the  Closing  Date,  within  fifty (50) days of the
Closing.

                                     (ii)  The  Closing  Cash  Payment  shall be
reduced  by $1.00  for  every  $1.00 or part  thereof  by which the net worth of
Company,  computed using the Closing Balance Sheet (the "Actual Net Worth"),  is
less than the  Estimated  Net Worth of Company,  and shall be increased by $1.00
for every  $1.00 or part  thereof  by which the  Actual  Net Worth of Company is
greater than the Estimated Net Worth of Company.

                                     (iii) The amount of the  adjustment  to the
Closing Cash Payment  pursuant to this Section 3.2(e),  if any, shall be due and
payable from Mayer to Cerprobe if the Closing  Cash Payment is reduced,  or from
Cerprobe to Mayer if the Closing Cash Payment is increased,  as the case may be,
in cash or by  certified  check,  within  fifteen  (15) days  following  Mayer's
receipt of the Closing  Balance  Sheet,  or, if Mayer  disputes the  information
contained in the Closing Balance Sheet or Cerprobe's calculations based
                                        5
<PAGE>
thereon, five (5) days following the final resolution of the dispute as provided
for in Section  3.2(e)(iv)  below.  Cerprobe  may but shall not be  required  to
resort to its rights under the Escrow and  Security  Agreement  (as  hereinafter
defined) to collect sums due from Mayer pursuant to this Section 3.2(e).

                                     (iv) In the event that Mayer shall  dispute
the  information  set  forth  by  Cerprobe  in the  Closing  Balance  Sheet,  or
Cerprobe's  computation  of the Actual  Net Worth of Company as of the  Closing,
then  within  ten (10)  business  days  following  the date of the  delivery  by
Cerprobe of its calculation of Actual Net Worth of Company,  Mayer shall provide
written  notice to Cerprobe  specifying  generally  the amount  disputed and the
basis for the dispute  together with  supporting  documentation  reflecting  the
analysis of and  justification  for any  recomputation  made. Mayer and Cerprobe
shall make good faith efforts to resolve the dispute  through  negotiation for a
period of ten (10)  business  days  following  the written  notice from Mayer to
Cerprobe  identifying and describing generally the nature of the dispute. In the
event the parties are unable to finally resolve the dispute within such ten (10)
business day period, the parties to the dispute may elect by mutual agreement to
extend the period of negotiation  (and may elect by mutual agreement to engage a
mediator to assist in such  negotiation).  To the extent that any matter remains
unresolved following negotiations, the unresolved matters only shall be resolved
by binding  arbitration  before one (1) arbitrator who shall be an audit partner
at the San Jose,  California office of the independent public accounting firm of
Ernst & Young LLP having not less than ten (10) years of audit  experience.  The
selection of the  arbitrator  shall be made by the  managing  partner of the San
Jose,  California  office  of Ernst & Young  LLP,  in the  exercise  of his sole
discretion.  The decision of the arbitrator  shall be a final  resolution of the
parties'  dispute  and  non-appealable  and  shall  not be  subject  to  further
arbitration  or review.  Each party to the dispute  shall bear their  respective
expenses incurred in respect of the dispute,  however, all costs and expenses of
the arbitrator shall be borne equally by Mayer and Cerprobe.

                           (f) Determining Net Worth.  The costs and commissions
incurred by Company in connection  with the Merger,  including,  but not limited
to, legal,  accounting,  consulting  and broker costs and  commissions  shall be
taken into account in  determining  the  Estimated  Net Worth and the Actual Net
Worth of Company; provided,  however, that only one half (1/2) of the Accounting
Fees  (as  defined  in this  Section  3.2(f))  shall be taken  into  account  in
determining  the  Estimated  Net Worth  and the  Actual  Net  Worth of  Company.
"Accounting  Fees"  means  the KPMG Peat  Marwick  fees for work  performed  for
Company in connection with the financial  statements of Company at September 30,
1996, December 31, 1996 and the Closing Balance Sheet.

anything in this Agreement to the contrary, shares of the Company Stock that are
issued and outstanding immediately prior to the Effective Time and that are held

General Corporation Law (the "Dissenting Shares"), shall not be exchangeable for
any shares of the  Cerprobe  Stock or any portion of the Closing Cash Payment as
adjusted  in Section  3.2(e)  hereof,  unless and until such  holder  shall have
failed to perfect or shall have  effectively  withdrawn or lost his/her right to
appraisal  and payment under the  California  General  Corporation  Law. If such
holder  shall have so failed to perfect or shall have  effectively  withdrawn or
lost such right, his/her shares shall thereupon be deemed to have been exchanged
into and to have become  exchangeable for, upon the Effective Time, the right to
receive  the number of shares of the  Cerprobe  Stock and portion of the Closing
Cash  Payment as adjusted in Section 3.2 hereof,  without  interest  thereon and
subject to the other provisions of Section 3.2 hereof.

                  3.5 Company  Warrants  and Options.  No Cerprobe  Stock or any
other  securities of Cerprobe of any nature and type  whatsoever,  including any
options or  warrants  to  acquire  the  Cerprobe  Stock or other  securities  of
Cerprobe  shall be issued in  connection  with or in exchange  for any  options,
warrants or other  rights to acquire  stock of Company.  Mayer shall have caused

canceled, and to be of no further force or effect, prior to the Closing.

owned  directly or  indirectly  by Company as treasury  stock,  shall,  upon the
Merger,  be cancelled and all rights with respect  thereto shall cease to exist,
and no shares of the Cerprobe Stock shall be issued or exchanged therefor.

                  3.7 Fractional  Shares.  No fractional  shares of the Cerprobe
Stock or any scrip shall be distributed  upon the exchange of the Cerprobe Stock

any,  shall be converted into the nearest whole share (half shares being rounded
down).

                  3.8 Cerprobe  Common Stock and Closing  Cash  Payment.  At the
Closing, Mayer shall deliver to Acquisition stock certificates  representing the
Company Stock. At the Closing,  Cerprobe shall deliver to Mayer the Closing Cash
Payment  and stock  certificates  representing  the  Cerprobe  Stock;  provided,
however,  that if Cerprobe is unable to deliver stock certificates  representing
the  Cerprobe  Stock at the  Closing,  then  Cerprobe  will  deliver  such stock
certificates to Mayer within three (3) business days of the Closing.

                  3.9 Restricted Stock. The Cerprobe Stock to be issued pursuant
to  Section  3.2  hereof,  will be  "Restricted  Stock"  and will not have  been
registered under the Securities Act of 1993, as amended (the "1933 Act"), or any

or as Cerprobe deems appropriate:

       THE  SHARES  REPRESENTED  BY THIS  CERTIFICATE  HAVE  NOT BEEN
       REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR ANY
       STATE SECURITIES ACT, AND ARE "RESTRICTED  SECURITIES"  WITHIN

       TRANSFERRED,  HYPOTHECATED  OR  OTHERWISE  DISTRIBUTED  IN THE
       ABSENCE OF AN  EFFECTIVE  REGISTRATION  UNDER SUCH ACTS OR THE
       RECEIPT OF AN OPINION  OF COUNSEL  SATISFACTORY  TO THE ISSUER
       THAT SUCH REGISTRATION IS NOT REQUIRED.

                  3.10 Escrow of the  Cerprobe  Stock.  At the  Closing,  Mayer,
Cerprobe  and an escrow agent (the  "Escrow  Agent")  shall have entered into an

its  respective  terms and  conditions,  and will continue as such following the

                  default,  or event or  condition  which,  with or without  the

                                            (ii)   no   party   to  any  of  the
                  Contracts has given any notice of default or termination,  nor

                  right  under  or with  respect  to any of the  Contracts,  the

                  the  financial  condition,  business,  operations,  assets  or
                  business prospects of Company.

                  Except as disclosed in Schedule 5.3(m) hereto,  Mayer does not
believe  that there is a  likelihood  that any of the  material  customers of or
material suppliers to Company will terminate its or their business  relationship
with Company for any reason whatsoever, including, without limitation, by reason
of the Merger and/or any change in ownership of Company.

                  Except as accurately  and  specifically  disclosed on Schedule
5.3(m) hereto,  there have not been,  and there is not pending or  contemplated,
any  transactions  between  Company and Mayer, or between Company and any of the

respect to its business and assets (such policies are hereinafter referred to as
the  "Policies").  Except as disclosed in Schedule 5.3(n) hereto,  the insurance
coverage  provided by the  Policies  presently in force will not in any material
respect  be  affected  by,  and will not  terminate  or lapse by reason  of, the
transactions contemplated hereby. Except as disclosed in Schedule 5.3(n) hereto,
at no time  subsequent to January 1, 1991, has Company been denied  insurance or
indemnity bond coverage.  Except as disclosed in Schedule  5.3(n) hereto,  at no

reduced  any  insurance  coverage  for  Company  or given  any  notice  or other
indication of its intention to cancel or reduce any such coverage.

disclosed in Schedule  5.3(o) hereto,  Company owns or has the necessary  rights
with  respect  to any  patents  and  copyrights  that are used by Company in the
conduct of its business and to Mayer's best knowledge and belief owns or has the

in  Schedule  5.3(o)  hereto,  none of the matters  covered by the  Intellectual
Property,  nor any of the products or services sold or provided by Company,  nor
any of the  processes  used  or the  business  practices  followed  by  Company,
infringes or has infringed  upon any  trademark,  trade name,  fictitious  name,
service  mark,  patent  or  copyright  owned by any  person  or  entity  (or any
application with respect thereto), or constitutes unfair competition. Company is
not  obligated  to pay any royalty or other  payment  with respect to any of the

of its  business  and the  ownership  and  use of its  assets,  properties,  the
premises  occupied  by it and the  conduct of its  business  plans as  presently

                                     To Mayer's actual knowledge,  no person can
                                     validly claim to be a "contractor  to SVTR"
                                     as used in the Anderson Purchase Agreement.

                                     or  interest in or to any  technology  that
                                     SVTR has used before the  execution of this
                                     Agreement,  except what was purchased  from
                                     Anderson by SVTR  pursuant to the  Purchase
                                     Agreement.

                                     than  pursuant  to  the  Anderson  Purchase
                                     Agreement,  and  without  any  relationship
                                     with SILPRO, Inc.

                                     (ah) Accuracy of Documents, Representations
and Warranties. The copies of all documents furnished to Cerprobe,  Acquisition,
or any of its or their representatives by or on behalf of Company,  Mayer or any
of his,  its or their  representatives,  are  true,  complete  and  correct.  No
representation  or warranty of Company or Mayer  contained in this  Agreement or
the other agreements to be executed by Company or Mayer pursuant hereto,  and no
statement  contained  in the  exhibits,  the  schedules  or the other  documents
delivered  by  or  on  behalf  of  Company  or  Mayer,  or  his,  its  or  their
representatives  pursuant to or in connection  with this  Agreement or the other
agreements  to be executed by Mayer or Company  pursuant  hereto,  or any of the
transactions  contemplated hereby or thereby, contains any untrue statement of a
material fact, or omits to state any material fact required
                                       27

to be stated herein or therein in order to make the statements  contained herein
or therein not misleading.

                           5.4 Reliance.

                                     (a) By Cerprobe  and  Acquisition.  Neither
Cerprobe  nor  Acquisition  is relying  on any oral or written  representations,
warranties,  statements or assurances from Company or Mayer other than those set
forth in this  Agreement,  and those set forth in the  certificates,  documents,
exhibits or  schedules  delivered in  connection  with this  Agreement.  Neither
Cerprobe nor  Acquisition  has seen or heard of any  advertising of any offer to
sell the Company Stock.

                                     (b) By Mayer and Company.  Neither  Company
nor  Mayer  is  relying  on any  oral or  written  representations,  warranties,
statements or assurances from Cerprobe or Acquisition other than those set forth
in this Agreement, and those set forth in the certificates,  documents, exhibits
or schedules delivered in connection with this Agreement.

                           5.5 Best Knowledge and Belief.  A  representation  or
warranty that is made to the "best  knowledge and belief" of Company or Mayer is
based on (a) the knowledge Mayer actually has, (b) the knowledge Mayer should be
expected  to have as  someone  who is the  sole  shareholder  and  President  of
Company, directly involved with and responsible for the day to day operations of
Company,  and  (c)  the  knowledge  he  could  have  obtained  after  performing
reasonable  due  diligence  that  would  include  but not be  limited  to making
appropriate inquiries of Company's managers, employees and 1996 consultants.

                           5.6   Disclosures.   Mayer  and   Company   may  make
disclosures  on the schedules  referred to in Section 5.3 hereof that may not be
required by this Agreement to be disclosed,  and the disclosure of such a matter
shall not create any inference that similar  matters,  or that other matters not
expressly  required by this Agreement to be disclosed on a schedule  referred to
in Section 5.3 hereof, are required to be disclosed.

                                 Indemnification

                           7.1 Indemnification in General.

                                     (a) By Mayer.  Subject  to the other  terms
and  conditions  of this  Agreement,  Mayer  shall  defend,  indemnify  and hold
harmless Cerprobe and Acquisition,  and their officers and directors,  for, from
and against any Indemnifiable  Loss (as hereinafter  defined) resulting from the
breach or inaccuracy of any of the representations or warranties (except for the
Excluded  Representations  and  Warranties  that are dealt  within  Section  7.4
hereof) of Mayer contained in this Agreement or the Investment Agreement, by and
between Mayer and Cerprobe, dated the date hereof (the "Investment Agreement").

                                     (b) By Cerprobe and Acquisition. Subject to
the other terms and conditions of this Agreement, Cerprobe and Acquisition shall
defend,   indemnify  and  hold  harmless  Mayer,   for,  from  and  against  any
Indemnifiable  Loss  resulting  from (i) the breach or  inaccuracy of any of the
representations  or  warranties  of Cerprobe and  Acquisition  contained in this
Agreement or the Investment Agreement; (ii) the failure of Acquisition to pay or
perform any of the  liabilities or  obligations  to the extent  disclosed on the
September  Balance Sheet or to the extent disclosed in the Disclosure  Schedules
referred  to in  Section  5.3  hereof,  provided  Cerprobe's  and  Acquisition's
obligations  under this Section  7.1(b) do not in any way relieve Mayer from his
obligations  under this Agreement that arise as a result of a breach by Mayer of
a representation,  warranty or covenant;  and (iii) the operation of Acquisition
after the Effective Time,  except for an obligation  caused by the misconduct of
Mayer.

                           7.2 Indemnifiable Loss.

                                     (a) General.  Subject to the  conditions to
indemnifications  set forth in this  Agreement,  Cerprobe and  Acquisition,  and
Mayer,  as the case may be, shall be  indemnified  under this  Agreement if, and
only to the extent,  Cerprobe and  Acquisition,  and Mayer,  as the case may be,
suffer an Indemnifiable  Loss. An Indemnifiable Loss is the out-of-pocket  harm,
net of tax effect,  actually suffered by reason of a breach or inaccuracy of any
of the  representations,  warranties or covenants contained in this Agreement or
the  Investment   Agreement.   An  Indemnifiable   Loss  includes  all  damages,
liabilities,  costs, expenses,  fines, taxes, and penalties,  and all attorneys'
fees and charges, expert witness fees,
                                       29
<PAGE>
and other  out-of-pocket  expenses of  investigating  and defending  against any
indemnifiable claim.

                                     (b)  Calculation.  The following shall also
apply in determining an Indemnifiable Loss:


                                            (i)  An   Indemnifiable   Loss  with
respect to an asset may not exceed its fair market value.  Indirect,  diminution
of value, consequential, or punitive damages are not Indemnifiable Losses.

                                            (ii)  To the  extent  that a loss is
recovered from insurance proceeds, the loss is not an Indemnifiable Loss.

                                            (iii) There is no Indemnifiable Loss
until the  aggregate  out-of-pocket  losses  exceed  $25,000,  and then only the
amount in excess of the $25,000  shall be an  Indemnifiable  Loss.  This Section
7.2(b)(iii)  applies only to claims  against  Mayer and does not apply to claims
against Cerprobe or Acquisition (or both).

                                     (c) No Multiple Recovery.

                                            (i) To the  extent  a  liability  or
expense or the  omission of an asset is taken into  account in  determining  the
merger   consideration   payable  to  Mayer,   a   corresponding   breach  of  a
representation  and  warranty  by reason of such  liability,  expense,  or asset
omission does not constitute an Indemnifiable Loss.

                                            (ii) If more than one representation
and  warranty is breached by the same set of facts,  the  Indemnifiable  Loss is
determined  by  the  set  of  facts  and  is  not  affected  by  the  number  of
representations and warranties breached.

                                     (d)  Example of  Contract  Exclusion.  If a
representation  and warranty is breached by the omission of a material  contract
from a Disclosure  Schedule,  but Acquisition elects not to cancel the contract,
then there is no Indemnifiable  Loss. If the omitted contract  requires payments
of $48,000 per year but is cancellable on one month's  notice,  and  Acquisition
cancels the contract at an out-of-pocket  cost of $4,000, the Indemnifiable Loss
is $4,000.  If such contract is  noncancellable  and Acquisition pays $25,000 in
damages for cancellation and $10,000 in attorney's fees, the Indemnifiable Loss,
before tax effect, is $35,000.

                                     (e) Escrow and Security  Agreement.  Except
as set forth in Section 7.4 hereof,  the sole source  Cerprobe  and  Acquisition
shall have for indemnification under Section 7.1(a) of this Agreement is Mayer's
shares of  Cerprobe  Stock  while held in escrow  under the Escrow and  Security
Agreement, and all claims against Mayer's shares of
                                       30
<PAGE>
Cerprobe stock under the Escrow and Security  Agreement must be made by July 15,
1998 and if not made by July 15, 1998, shall lapse.

                           7.3  Nature  and   Effect  of   Representations   and
Warranties.

                                     (a)  Those  Made By Mayer.  Except  for the
Excluded   Representations   and  Warranties  (as  hereinafter   defined),   the
representations  and warranties  made by Mayer in this Agreement are made on the
condition that such  representations  and warranties shall create liability only
with respect to indemnification expressly provided for by this Agreement or with
respect to any  statutory or common law right to rescind the Merger  (based upon
the  representations  and  warranties  taken  as  a  whole,  together  with  the
Disclosure  Schedules),  and  Cerprobe  and  Acquisition  are not relying on the
representations  and  warranties  of Mayer for any other  purpose.  Except for a
breach of a  representation  and warranty  relating to any of the following (the
"Excluded  Representations  and Warranties"):  (i) ownership and title to any of
the assets of Company; (ii) ownership and title to the capital stock of Company;
(iii)  competency  to execute and deliver  documents to effect the  transactions
contemplated in this Agreement,  and the legal,  binding and enforceable  nature
hereof and thereof; (iv) taxes; and (v) the environment,  the sole and exclusive
remedy of Cerprobe and Acquisition for a breach of a representation and warranty
by  Mayer  shall  be the  right  of  indemnification  as  provided  for in  this
Agreement. Cerprobe and Acquisition shall have all rights and remedies available
to them for a breach of any of the Excluded Representations and Warranties,  for
a breach by Mayer of any of the covenants  contained in this Agreement,  for any
fraud committed by Mayer, and (unless  otherwise  specifically  limited therein)
for a breach  by Mayer of any of the  covenants  contained  in any of the  other
agreements entered into by Mayer in connection with this Agreement.

                                     (b) Those Made By Cerprobe and Acquisition.
The repre-  sentations and warranties  made by Cerprobe and  Acquisition in this
Agreement are made on the condition  that such  representations  and  warranties
shall create liability only with respect to  indemnification  expressly provided
for by this  Agreement or with  respect to any  statutory or common law right to
rescind the Merger (based upon the  representations  and  warranties  taken as a
whole),  and Mayer is not relying on the  representations  and  warran-  ties of
Cerprobe and Acquisition for any other purpose. The sole and exclusive remedy of
Mayer for a breach of a representation  and warranty by Cerprobe and Acquisition
shall be the right of indemnification  as provided for in this Agreement.  Mayer
shall have all rights and remedies  available to him for a breach by Cerprobe or
Acquisition of any of the covenants  contained in this Agreement,  for any fraud
committed by Cerprobe or Acquisition, and (unless otherwise specifically limited
therein)  for a  breach  by  Cerprobe  or  Acquisition  of any of the  covenants
contained in any of the other agreements entered into by Cerprobe or Acquisition
in connection with this Agreement.

                           7.4   Additional   Indemnification   By  Mayer.   The
provisions  of Section  7.2  hereof  shall not apply to, and shall not limit any
rights or claims by Cerprobe or Acquisition for, the following:

                                     (a)    Excluded     Representations     and
Warranties.  Mayer shall defend,  indemnify  and hold harmless  Cerprobe and the
Surviving Corporation,  and their officers and directors,  for, from and against
any and all damages,  losses,  liabilities  (absolute  and  contingent),  fines,
penalties, costs and expenses (including, without limitation, reasonable counsel
fees and costs and expenses incurred in the investigation, defense or settlement
of any claim covered by this  indemnity)  ("Losses")  with respect to or arising
out of any demand, claim, inquiry, investigation, proceeding, action or cause of
action ("Claim") which Cerprobe, the Surviving Corporation, or their officers or
directors,  may suffer or incur by reason of the breach or  inaccuracy of any of
the Excluded Representations and Warranties.

                                     (b)  Environmental.   Mayer  shall  defend,
indemnify  and hold harmless  Cerprobe,  the  Surviving  Corporation,  and their
officers and directors, for, from and against any and all Losses with respect to
or arising out of any Claim which Cerprobe, the Surviving Corporation,  or their
officers, directors and shareholders may suffer or incur by reason of:

                                            (i) any generation,  transportation,
storage, treatment or disposal of any hazardous substances,  solids or wastes as
contemplated in Section 5.3(af) hereof ("Hazardous  Substances") by or on behalf
of  Company  occurring  on or prior to the  Effective  Time  including,  without
limitation,  any waste or other disposal activities or discharges which occurred
at a facility on which a portion of Company's  (or its  predecessors')  business
was  conducted,  any waste or other  disposal  activities  or  discharges  which
occurred  off of any such  facility  with regard to wastes and other  substances
generated  on such  facility,  and any  waste or other  disposal  activities  or
discharges  which occurred on real estate at any time whether or not Company (or
its  predecessors)  owned or leased  such real  estate at the time such waste or
other  disposal  activities  or  discharges  were engaged in, and whether or not
Company performed such waste or other disposal activities or discharges;

                                            (ii)  any  releases  or   threatened
releases as defined now or in the future under the  Comprehensive  Environmental
Response,  Compensation,  and Liability Act of 1980, P.L. 96-510,  as amended or
reauthorized  from time to time,  or any other similar  federal,  state or local
laws,  statutes,  rules or  regulations  occurring on or prior to the  Effective
Time, including,  but not limited to, (A) those releases of Hazardous Substances

which occurred prior to the Effective  Time, of any  requirements  imposing such
notification or reporting obligations or
                                       32

requirements;

                                            (iii) any discharges by or on behalf
of  Company  or as a result of any  activities  by or on behalf  of  Company  to
surface waters or groundwaters occurring on or prior to the Effective Time;

                                            (iv) any air  emissions  of  Company
occurring on or prior to the Effective Time;

                                            (v) the  exposure  of and  resulting
consequences  to any  persons,  including,  but not  limited to, past or present
employees of Company or the Surviving Corporation,  to any mineral,  chemical or
industrial product,  raw material  intermediate,  by-product or medical or other
waste, or substance created, generated,  processed,  handled or originating at a
facility at which Company (or any of its predecessors)  conducted business on or
prior to the Effective Time or otherwise used by Company (or any of its or their
predecessors) in the conduct of its business;

                                            (vi) any  violations by or on behalf

upkeep of on-site storage,  treatment and disposal facilities on or prior to the

limit.  This  Section  is  intended  to limit and not expand  Mayer's  potential
liability.

<PAGE>
                           7.6 Claims Under Escrow and Security Agreement. On or
before the  forty-fifth  (45th) day after the close of each calendar  quarter in
1997 and 1998 (provided the forty-fifth (45th) day is a business day and if not,
then the next business day following  the  forty-fifth  (45th) day) Cerprobe and
Acquisition  shall  notify Mayer of any claims they have  discovered  during the
prior  quarter for which they may seek  recourse  under the Escrow and  Security
Agreement.

                           7.7  Notice and Right to Defend  Third-Party  Claims.
Promptly  upon  receipt  of notice of any  claim,  demand or  assessment  or the
commencement  of any suit,  action or proceeding with respect to which indemnity
may be sought pursuant to this Agreement, the party seeking to be indemnified or
held harmless (the "Indemnitee")  shall notify in writing,  if possible,  within
sufficient  time to respond to such claim or answer or  otherwise  plead in such
action  (but in any  event  within  thirty  (30)  days),  the  party  from  whom
indemnification  is sought  (the  "Indemnitor").  In case any  claim,  demand or
assessment shall be asserted,  or suit,  action or proceeding  commenced against
the Indemnitee,  the Indemnitor shall be entitled,  at the Indemnitor's expense,
to  participate  therein,  and,  to the extent  that it may wish,  to assume the
defense,  conduct  or  settlement  thereof,  at its own  expense,  with  counsel
satisfactory to the Indemnitee,  whose consent to the selection of counsel shall
not be unreasonably  withheld or delayed,  provided that the Indemnitor confirms
to the  Indemnitee  that it is a claim to which its  rights  of  indemnification
apply.  The  Indemnitor  shall have the right to settle or  compromise  monetary
claims;  however,  as to any other claim,  the Indemnitor shall first obtain the
prior written consent from the  Indemnitee,  which consent shall be exercised in
the sole discretion of the  Indemnitee.  After notice from the Indemnitor to the
Indemnitee of Indemnitor's intent so to assume the defense, conduct,  settlement
or  compromise  of such  action,  the  Indemnitor  shall  not be  liable  to the
Indemnitee  for any  legal or other  expenses  (including,  without  limitation,
settlement costs) subsequently incurred by the Indemnitee in connection with the
defense, conduct or settlement of such action while the Indemnitor is diligently
defending,  conducting,  settling or  compromising  such action.  The Indemnitor
shall  keep the  Indemnitee  apprised  of the  status  of the  suit,  action  or
proceeding and shall make Indemnitor's  counsel available to the Indemnitee,  at
the  Indemnitor's  expense,  upon the request of the Indemnitee.  The Indemnitee
shall  cooperate with the Indemnitor in connection with any such claim and shall
make personnel,  books and records and other  information  relevant to the claim
available to the Indemnitor to the extent that such personnel, books and records
and other information are in the possession or control of the Indemnitee. If the
Indemnitor decides not to participate,  the Indemnitee shall be entitled, at the
Indemnitor's expense, to defend,  conduct, settle or compromise such matter with
counsel  satisfactory  to the  Indemnitor,  whose  consent to the  selection  of
counsel shall not be unreasonably withheld or delayed.

                                  Post-Closing
                                  ------------

                           8.1  Accounts  Receivable.  On June 30,  1997,  Mayer
shall  purchase from the Surviving  Corporation,  and the Surviving  Corporation
shall sell and assign to Mayer,  all  accounts  receivable  of Company as of the
Closing (the "Accounts  Receivable") that have not been paid in full by June 30,
1997 (with the payments  received by the Surviving  Corporation being applied to
the Accounts Receivable the customer so designates,  or if the customer does not
designate or if the  Surviving  Corporation  directs the customer to designate a
specific  Accounts  Receivable,  then to the oldest Accounts  Receivable of that
customer) at the amount of the then outstanding Accounts Receivable. Acquisition
agrees to use reasonable efforts to collect the Accounts  Receivable,  but shall
not be  obligated  to initiate  legal  action in order to collect  the  Accounts
Receivable.  If Mayer does not  purchase  the  Accounts  Receivable  as required
pursuant to this Section 8.1,  then  Cerprobe and  Acquisition  may make a claim
under the Escrow and Security  Agreement  for the amount owed. At the time Mayer
purchases the Accounts  Receivable,  Acquisition shall execute a UCC-1 Financing
Statement evidencing the assignment of that Accounts Receivable to Mayer.

                           8.2 Nondisclosure/Confidentiality. From and after the
date of this  Agreement,  Mayer shall not disclose to any third party or use for
any purpose other than as  contemplated  by this  Agreement,  any proprietary or
confidential  information  regarding  Company,  Cerprobe  and  Acquisition.  The
preceding  sentence shall not apply to information  that (a) is, was, or becomes
generally  known or  available  to the  public or the  industry  other than as a
result  of a  disclosure  by  Mayer  in  violation  of this  Agreement;  (b) was
previously  known by  Mayer;  (c) is  subsequently  obtained  by  Mayer  from an
independent  third-party  source  having no  obligation  of  confidentiality  to
Company,  Cerprobe or  Acquisition;  or (d) is required to be  disclosed by law.
Mayer shall  advise  Company,  Cerprobe  and  Acquisition,  in  writing,  of any
request,  including a subpoena or similar  legal  inquiry,  to disclose any such
confidential  information,  so that Company,  Cerprobe and  Acquisition can seek
appropriate legal relief.

                  Mayer  acknowledges  that  the  covenants  contained  in  this
Section 8.2 are a material  inducement  for Cerprobe and  Acquisition to execute
and deliver this  Agreement  and to  consummate  the  transactions  contemplated
hereby. Accordingly,  Mayer acknowledges that the restrictions contained in this
Section 8.2 are  reasonable  and necessary for the protection of the business of
Company,  Cerprobe and  Acquisition,  and that a breach of any such  restriction
could not adequately be compensated by damages in an action at law. In the event
of a breach  or  threatened  breach  by Mayer of any of the  provisions  of this
Section 8.2, Company,  Cerprobe and/or  Acquisition shall be entitled to obtain,
without the necessity of posting bond therefor,  an injunction  (preliminary  or
permanent, or a temporary restraining order) restraining Mayer from the activity
or threatened activity  constituting or which would constitute a breach, as well
as damages and an equitable accounting of all
                                       35

earnings, profits and other benefits arising from a violation, which right shall
be cumulative  and in addition to any other rights or remedies to which Company,
Cerprobe and/or Acquisition may be entitled.

                  Each and  every  provision  set forth in this  Section  8.2 is
independent  and severable from the others,  and no provision  shall be rendered
unenforceable by virtue of the fact that, for any reason, any other or others of
them may be  unenforceable in whole or in part. The parties hereto agree that if
any  provision  of this  Section 8.2 shall be  declared by a court of  competent
jurisdiction  to be  unenforceable  for any  reason  whatsoever,  the  court may
appropriately limit or modify such provision,  and such provision shall be given
effect to the maximum extent permitted by applicable law.

                           8.3 Filing of Merger  Documents.  Cerprobe  agrees to
take all necessary  actions to file the Merger  Documents  with,  and obtain the
approval for such filing by, the  respective  Secretary of State for each of the
States  of  Delaware  and  California,  and Mayer  shall,  upon the  request  of
Cerprobe,  take all necessary  actions to assist  Cerprobe with such filings and
approvals.

                           8.4  Tax  Inquiry.  Cerprobe  or  Acquisition  shall,
within fifteen (15) days of being  notified of any tax inquiry or audit,  notify
Mayer of any tax inquiry or audit  concerning the operations of Company prior to
the Closing. Cerprobe,  Acquisition and Mayer agree to cooperate with each other
to resolve such tax inquiry or audit.

                           8.5 No Liquidation.  Cerprobe agrees not to liquidate
Acquisition for a period of two (2) years following the Closing.

                           8.6 Release of Silpro Shares and Guaranty.  Following
the Closing, Cerprobe shall return to Mayer all of his shares of SILPRO, Inc., a
California  corporation,  held by  Cerprobe  under  that  certain  Stock  Pledge
Agreement,  by and among Mayer and Cerprobe,  dated December 12, 1996, and shall
release Mayer from Mayer's  obligations  under that certain Payment  Guaranty by
and among Mayer and Cerprobe, dated December 12, 1996.

                           8.7 Company Tax. Except as otherwise provided in that
certain Indemnification Agreement, by and among Mayer, Cerprobe and Acquisition,
Mayer  is  not  responsible  for  any  corporate  income  tax  assessed  against
Acquisition as a result of the Merger if the Internal Revenue Service determines
that the Merger does not meet the requirements of Section 368(a) of the Code.

                                  Miscellaneous
                                  -------------

                           9.1 Disclosure  Schedules.  The Disclosure  Schedules
referred to in Section 5.3 of this  Agreement  reflect  information  supplied to
Cerprobe and Acquisition in the course of their investigation of Company.

                           9.2 Broker's  Fees. The parties hereto each represent
and warrant to the other that, except for the costs,  expenses and fees incurred
by Company for the services of Corporate  Strategic  Coventures,  the respective
warrantor  has not dealt with and is not aware of any dealings  with any person,
firm or corporation who is or may be entitled to a broker's commission, finder's
fee,  investment  banker's  fee or  similar  payment  from the  other  party for
arranging these transactions or introducing the parties to each other.

                           9.3 Fees and Expenses.

                                     (a)  General.  It is agreed that all costs,
expenses and fees of Company  incurred in connection with this Agreement,  shall
be borne by Company;  provided,  however, that such costs, expenses and fees are
included in the  calculation  of the Estimated Net Worth and Actual Net Worth of
Company,  as contemplated in Section 3.2 hereof.  All of the costs and expenses,
and fees of  Cerprobe,  including  legal and  accounting  services,  incurred in
connection with the herein proposed transactions, shall be borne by Cerprobe.

                                     (b)   Accounting   Fees.    Notwithstanding
anything to the contrary in Section 4.1 hereof, all of the Accounting Fees shall
be paid for by Company, but consistent with Section 3.2(f) hereof, only one half
(1/2) of the  Accounting  Fees will be taken  into  account in  determining  the
Estimated  Net Worth and  Actual Net Worth of  Company,  which has the effect of
Company and Cerprobe each paying one half (1/2) of the Accounting Fees.

                           9.4 Public  Announcements.  Cerprobe  and Mayer shall
consult  with each other  before  issuing any press  release with respect to the
Merger or this  Agreement and shall not issue any such press release or make any
such public statement without the prior consent of the other party,  which shall
not be unreasonably withheld;  provided, however, that Cerprobe may, without the
prior consent of Mayer,  issue such press release or make such public  statement
if Cerprobe is required by law, and Cerprobe  may,  without the prior consent of
Mayer,  make such filings with the Securities and Exchange  Commission as may be
required by law.

                           9.5 Notices.  All notices required or permitted to be
given  hereunder shall be in writing and shall be deemed given when delivered in
person,  or three  (3)  business  days  after  being  placed  in the hands of an

                           9.6 Entire Agreement.  This Agreement constitutes the
entire agreement  between the parties and shall be binding upon and inure to the
benefit  of the  parties  hereto  and their  respective  legal  representatives,
successors  and permitted  assigns.  Each exhibit and schedule to this Agreement
shall be considered  incorporated into each of the respective  agreements.  This
Agreement  supersedes all prior written or oral  agreements  between the parties
hereto and thereto.

                           9.7 Waivers. The failure in any one or more instances
of a  party  to  insist  upon  performance  of any of the  terms,  covenants  or
conditions of this  Agreement,  to exercise any right or privilege  conferred in
this  Agreement  or the  waiver by said party of any breach of any of the terms,
covenants  or  conditions  of  this  Agreement,  shall  not  be  construed  as a
subsequent  waiver  of  any  such  terms,  covenants,   conditions,   rights  or
privileges,  but the same shall  continue and remain in full force and effect as
if no such  forbearance  or waiver had  occurred.  No waiver  shall be effective
unless it is in  writing  and  signed  by an  authorized  representative  of the
waiving party. A breach of any representation, warranty or covenant shall not be
affected  by the  fact  that a more  general  or more  specific  representation,
warranty or covenant was not also breached.

                           9.8  Counterparts.  This Agreement may be executed in

such counterparts shall constitute but one instrument.


                           9.9  Attorneys'  Fees.  If any  action is  brought to
enforce this  Agreement or to collect  damages as a result of a breach of any of
its  provisions,  the  prevailing  party  shall also be  entitled to collect its
reasonable  attorneys'  fees and costs incurred in such action,  which costs can
include the reasonable costs of investigation, expert witnesses and the costs in
enforcing or collecting any judgment rendered.

                           9.10 Severability. The invalidity of any provision of
this  Agreement  or portion of a provision  shall not affect the validity of any
other  provision of this  Agreement or the remaining  portion of the  applicable
provision.

                           9.11 Applicable Law. This agreement shall be governed
by and construed and enforced in accordance  with the internal laws of the State
of Arizona without regard to the conflict of laws principles of such state.

                           9.12 Further  Assurances.  The parties  shall execute
such further  documents,  and perform such further  acts, as may be necessary to

$.05 per share,  of Cerprobe (the "Common  Stock") for the account of any holder
of  Common  Stock  other  than:  (i)  Shareholder;  or (ii) for the  account  of
Cerprobe,  and other than a  registration:  (aa) on Form S-4; (bb) in connection
with a Rule 145  transaction;  (cc) on Form S-8;  or (dd) any other  appropriate
form or any  successor  or other  comparable  form,  then on each such  occasion
Cerprobe shall give
                                        1
<PAGE>
Shareholder  at least  fifteen  (15) days prior  written  notice of the  initial
filing of the Registration Statement (the "Filing Notice").

         If  Shareholder  desires  to have any of the Shares  registered  in the
Registration  Statement,  then  Shareholder  shall notify Cerprobe in writing of
Shareholder's desire and deliver such written notice to Cerprobe within ten (10)
days of  receiving  the Filing  Notice  from  Cerprobe.  If  Shareholder  timely
notifies Cerprobe of Shareholder's  desire to register the Shares for sale, then
Cerprobe,  with the consent and the  approval  of the  underwriters  selected by
Cerprobe  to  assist  Cerprobe  in the  offering  covered  by  the  Registration
Statement  (such  consent  and  approval  to be in the sole  discretion  of such
underwriters),  shall include in that Registration  Statement, on the same terms
and  conditions  (except as otherwise  provided in this  Agreement) as the other
Common  Stock to be offered  for sale  pursuant  to the  Registration  Statement
(except as otherwise  provided in this  Agreement),  the following number of the
Shares,  or such smaller number of the Shares as Shareholder shall elect to have
registered:

                                          B
                                     A x ---
                                          C

Where A equals the total number of Shares  acquired by  Shareholder  pursuant to
the  Agreement of Merger that are held of record by  Shareholder  on the date of
the Filing Notice; and

Where B equals the number of shares of Common  Stock  being  registered  for the
person,  firm or entity (other than Cerprobe) for whom the largest percentage of
shares of Common Stock held by him, her or it is being registered; and

Where C equals the total  number of shares of Common  Stock held by such person,
firm or entity.

                  (b) Notwithstanding any other provisions of this Section 1, if
the  underwriters  selected  by  Cerprobe  advise  Cerprobe  that,  in the  sole
discretion of such  underwriters,  marketing factors require a limitation on the
number  of shares to be  underwritten,  then  Cerprobe  may  exclude  all or any
portion of the shares of Common Stock or  Shareholder's  Shares to be registered
by the  holders  thereof  (other than by  Cerprobe)  or limit the number of such
shares or Shareholder's Shares to be included.  Any such reduction shall, to the
extent  reasonably  practicable,  be  allocated  among such  holders,  including
Shareholder,  pro rata on the  basis  of the  number  of  shares  requested  for
inclusion in the Registration Statement.

                  (c) All brokerage  fees,  discounts and commissions in respect
of the  registration  of the Shares or any portion  thereof under this Agreement
and applicable transfer taxes payable upon the sale of the Shares so registered,
in connection  with the  registration of the Shares or any portion thereof under
this Agreement  shall be paid and borne by Cerprobe to the extent paid and borne
by Cerprobe for any other shareholder (other than Cerprobe) selling Common Stock
under the Registration Statement, otherwise such fees, discounts and commissions
shall be paid and
                                        2
<PAGE>
borne  by  Shareholder.  Any  counsel  fees or  disbursements  for  counsel  for
Shareholder and any  out-of-pocket  expenses  otherwise  incurred by Shareholder
shall be paid and borne by Shareholder.

                  (d) If any piggyback  registration of Cerprobe's  Common Stock
in which  Shareholder  elects to  participate  under this  Agreement is to be an
underwritten offering,  the selection of underwriters,  investment banker(s) and
manager(s)  for the offering  shall be solely at the  discretion of the Board of
Directors of Cerprobe.

         2.  Lock-up  Agreements.  If any  portion  of  Shareholder's  Shares is
registered in the Registration Statement (the "Registration"),  then Shareholder
shall not,  unless the  underwriters  selected  by Cerprobe  otherwise  agree in
writing,  effect any public sale or distribution of any other equity  securities
of Cerprobe,  or any securities  convertible into or exchangeable or exercisable
for those  securities,  during the period  commencing  on the filing date of the
Registration  Statement  with the SEC, and ending one hundred  eighty (180) days
after the effective date of any such Registration,  or such longer period as the
other selling shareholders (other than Cerprobe) may agree.

         3. Registration Procedures. Whenever Shareholder has requested that the
Shares, or any portion thereof, subject to this Agreement be registered pursuant

of disposition thereof, and pursuant thereto Cerprobe will:

                  (a)  prepare  and file with the SEC a  Registration  Statement
with  respect  to such  Shares  and use its  reasonable  efforts  to  cause  the
Registration Statement to become effective;  provided,  however,  Cerprobe shall
have the sole right and discretion to withdraw or terminate any Registration;

                  (b) furnish to Shareholder such reasonable number of copies of
the  Registration   Statement,   each  amendment  and  supplement  thereto,  the
prospectus included in such Registration  Statement  (including each preliminary
prospectus)  in order to  facilitate  the  disposition  of such Shares  owned by
Shareholder; and

                  (c)  provide  or  continue  to  provide a  transfer  agent and
registrar for such Shares not later than the effective date of the  Registration
Statement.

         4.  Registration  Expenses.  Except  as  otherwise  set  forth  in this
Agreement, all expenses incident to Cerprobe's performance of or compliance with
this Agreement, including all registration and filing fees, fees and expenses of
compliance with securities or blue sky laws,  printing  expenses,  messenger and
delivery  expenses,  and fees and  disbursements of counsel for Cerprobe and all
independent  certified public accountants of Cerprobe,  underwriters  (excluding
brokerage  fees,  discounts  and  commissions)  and other  persons  retained  by
Cerprobe will be borne by Cerprobe.

Shareholder  elects to participate,  Shareholder  agrees to cooperate fully with

Stock and Shareholder's  Shares and of such distribution of the shares of Common
Stock and Shareholder's Shares.

         6.  Participation  in  Underwritten   Registrations.   Shareholder  may
participate in any Registration pursuant to this Agreement which is underwritten
only if Shareholder (a) agrees to sell his Shares being  registered on the basis
provided in any underwriting  arrangements approved by the Board of Directors of
Cerprobe, and (b) completes and executes all questionnaires, powers of attorney,
indemnities,  underwriting  agreements  and other  documents  required under the
terms of such underwriting arrangements.

         7. Termination of Company  Obligations.  Cerprobe's  obligations  under
this  Agreement to register the Shares or any portion  thereof  shall  terminate
upon the earlier of (i) receipt by Cerprobe of an opinion  from its counsel that
registration  is not  required  under the 1933 Act in order for  Shareholder  to
publicly sell any of the Shares;  (ii) receipt by Shareholder  from the SEC of a
"no-action"  letter to the effect  that the staff of the SEC will not  recommend
that  the SEC  institute  action  against  Shareholder  in  connection  with the
proposed sale of the Shares, or any portion thereof; or (iii) January 15, 2000.

         8. Miscellaneous.

Shareholder  to any  shares of the Common  Stock,  except as  permitted  in this
Section  8(a),  without the prior written  consent of Cerprobe  exercised in its
sole discretion.

         NOW,  THEREFORE,  in  consideration  of the foregoing  recitals and the
mutual covenants set forth in this Agreement, the parties agree as follows:

                  1.  Employment.  Employer hereby employs Employee and Employee
hereby accepts such  employment,  to perform such duties and services for and on
behalf of  Employer as may,  from time to time,  be  determined  by the Board of
Directors or  President of Employer,  as  applicable,  and are  consistent  with
Sections 1(a),  1(b) and 1(c) hereof.  Subject to Sections  1(a),  1(b) and 1(c)
hereof,  Employee  shall devote  Employee's  full and undivided  business  time,

                           (b) Termination.  Notwithstanding  anything contained
in this Agreement to the contrary,  Employee's  employment hereunder is entirely
at will, and may be terminated by Employer with or without  cause,  subject only
to the payment obligations of Employer as hereafter set forth.

                                    (i)  In  the   event   Employer   terminates
Employee's  employment  hereunder for Cause (as hereafter  defined),  Employee's
employment  hereunder shall immediately  terminate on the effective date of such
termination as  established by Employer,  and Employee shall only receive Salary
and any other benefits under this Agreement  prorated through the effective date
of Employee's termination.

                                    (ii)  In  the  event   Employer   terminates
Employee's  employment  hereunder  without Cause, then for the remaining term of
this Agreement,  as severance pay and as total  compensation and restitution for
such  termination,  Employee  shall  receive  for  the  remaining  term  of this
Agreement:  (A)  Employee's  Salary which shall be paid at the times it would be
paid if Employee was still employed by Employer under this Agreement, subject to
the same deductions and withholdings,  and (B) either, at Employer's discretion,

Employee was still  employed by Employer  under this  Agreement or (2) the COBRA
amount  necessary  for  Employee to maintain  such medical  benefits;  provided,
however,  that if Employee accepts  employment  during the remaining term of the
Agreement and as part of that  employment  Employee  receives  medical  benefits
similar to those Employee received  immediately prior to such termination,  then
Employer's  obligations under this Section  4(b)(ii)(B) shall terminate early on
the date Employee begins receiving such medical benefits from his new employer.

                           (c) Cause.  For purposes of this  Agreement,  "Cause"
means:  (i)  "Total  and  Permanent  Incapacity"  (as  hereinafter  defined)  of
Employee;  (ii) the failure or inability  (not as a consequence  of any illness,
accident or other  disability,  as confirmed by competent  medical  evidence) of
Employee  to  perform   Employee's  duties  hereunder  in  a  manner  reasonably
satisfactory  to  Employer's  Board of  Directors,  provided the decision of the
Board of Directors is not arbitrary or capricious,  and is not made in bad faith
and  further  that the  failure  or  inability  is not as a  consequence  of any
illness,  accident  or  other  disability  as  confirmed  by  competent  medical
evidence;  (iii) "Serious Misconduct" (as hereinafter  defined) of Employee;  or
(iv) the breach of any of the terms or conditions contained in this Agreement.

                           For purposes of this Agreement,  "Total and Permanent
Incapacity"  means such  physical or mental  condition  of  Employee,  including
alcoholism,  which renders Employee  incapable of performing  Employee's  duties
hereunder for more than 90 days. In the event Employee is a Qualified Individual
with a Disability,  as defined in the American with  Disabilities  Act, Employer
shall not  terminate  Employee's  employment  hereunder  if  Employee is able to
perform the  essential  functions of Employee's  job with or without  reasonable
accommodation from Employer.

                           For purposes of this Agreement,  "Serious Misconduct"
means embezzlement or misappropriation of corporate funds; the furnishing of any
information,  reports,  documents or  certificates by Employee to Employer which
Employee knew or believed to be false or  misleading;  dishonesty of any kind in
relations with Employer or its customers; activities harmful to the
                                        3
<PAGE>
reputation of Employer (other than as a consequence of good faith decisions made
by Employee in the normal  performance  of  Employee's  duties  hereunder);  the
conviction  of or the plea by Employee  to any  criminal  felony  offense or any
criminal  offense  regarding  dishonesty or moral  turpitude;  or the refusal to
perform the duties assigned to Employee  pursuant to this Agreement (unless such
duties shall be unlawful).

                           Employer  agrees to act in a commercially  reasonable
fashion in terminating for Cause,  and shall give Employee notice of any failure
by Employee to conform his conduct to the  requirements of this Agreement and an
appropriate amount of time to cure such failure,  the exact amount of time to be
determined by Employer in a commercially reasonable fashion, based upon the type
of failure  involved.  Employer  and  Employee  acknowledge  and agree that some
failures  (which  failures  Employer and Employee are not defining other than as
those failures  Employer  determines,  in a "commercially  reasonable  fashion,"
qualify) will not require any notice to be given, and Employee may be terminated
immediately for "Cause" in those situations.

                           Notwithstanding  anything contained in this Agreement
to the  contrary,  Employee  may  resign  and  terminate  Employee's  employment
hereunder, with or without cause, subject to the requirement that Employee shall
provide  Employer  with not less than 45 days'  prior  written  notice.  In such
event,  Employee  shall not receive any Salary or any other  benefits under this
Agreement after the effective date of Employee's resignation.

                           (d)  Death.  In the  event of the  death of  Employee
during the term of this  Agreement,  this  Agreement and  Employee's  employment
hereunder  shall  terminate  as of  the  date  of the  death  of  Employee,  and
Employee's estate or personal representative shall be entitled to receive Salary
and other fringe  benefits  prorated for the period of Employee's  employment to
the date of death, payable within 60 days after the date of death.

                           (e)  Suspension.  Employer  shall  have the  right to
suspend  Employee with full pay and benefits for any period of time the Board of
Directors of Employer deems, in its sole discretion, necessary or appropriate to
investigate Employee's conduct in connection with Section 4(c) hereof.

                  5. Noncompetition.  During the period of Employee's employment
hereunder,  and for a period of eighteen  (18) months from and after the date of
expiration or earlier  termination of Employee's  employment  hereunder (or such
lesser  period to the maximum  extent  permitted  by  applicable  law),  neither
Employee  nor any  person or  entity  controlled  (directly  or  indirectly)  by
Employee, whether as employer, employee, proprietor, partner, stockholder (other
than the holder of less than 5% of the stock of a corporation  the securities of
which are traded on a national  securities  exchange or in the  over-the-counter
market),  director,  officer,  consultant,  agent or otherwise, shall within the
Restricted  Territory (as defined below) engage or cause others to engage in the
Business unless first authorized in writing by Employer, which authorization may
be withheld in the sole and absolute  discretion  of  Employer.  For purposes of
this Agreement,  the term "Restricted Territory" shall mean the United States of
America,  and all other countries in which Employer conducts the Business on the
date  hereof.  If Employee  violates  Employee's  obligations  contained in this
Section 5, then the time  periods  hereunder  shall be extended by the period of
time  equal to that  period  beginning  when the  activities  constituting  such
violation  commenced and ending when the activities  constituting such violation
terminated.
                                        4
<PAGE>
                  6. Nonsolicitation. During the period of Employee's employment
hereunder,  and for a period of eighteen  (18) months from and after the date of
expiration or earlier  termination of Employee's  employment  hereunder (or such
lesser  period to the maximum  extent  permitted  by  applicable  law),  neither
Employee  nor any  person or  entity  controlled  (directly  or  indirectly)  by
Employee whether as employer, employee, proprietor,  partner, stockholder (other
than the holder of less than 5% of the stock of a corporation  the securities of
which are traded on a national  securities  exchange or in the  over-the-counter
market), director, officer, consultant, agent or otherwise, shall solicit (a) in
respect of the  Business,  any person or other entity that is, or was within the
previous 12 month period  immediately prior to the date of expiration or earlier
termination  of  Employee's  employment  hereunder,  a customer  or  supplier of
Employer,  or (b) any person who, on such date, is an employee of Employer,  for
employment,  or as an independent  contractor with any person or entity,  unless
first authorized in writing by Employer,  which authorization may be withheld in
Employer's  sole  and  absolute  discretion.  If  Employee  violates  Employee's
obligations  contained in this Section 6, then the time periods  hereunder shall
be  extended  by a  period  of time  equal  to that  period  beginning  when the
activities  constituting such violation commenced and ending when the activities
constituting such violation terminated.

                  7. Trade Secrets and Other Confidential Information.  From and
after the date hereof,  Employee shall not communicate or divulge to, or use for
the benefit of, any  person,  firm or  corporation  other than  Employer  and/or
Employer's subsidiaries, and its or their agents and representatives, any of the
trade secrets, methods, formulas,  business and/or marketing plans, processes or
any other  proprietary  or  confidential  information  with  respect to Employer
and/or  Employer's  subsidiaries,  its or their business,  financial  condition,
business operations or methods,  or business  prospects.  The preceding sentence
shall not apply to information  which (a) is, was or becomes  generally known or
available to the public or the  industry  other than as a result of a disclosure
by Employee in violation of this  Agreement,  or (b) is required to be disclosed
by law. Employee shall advise Employer, in writing, of any request,  including a
subpoena  or  similar  legal   inquiry,   to  disclose  any  such   confidential
information,   such  that  Employer  and/or  Employer's  subsidiaries  can  seek
appropriate legal relief.

                  8.  Return  of  Employer   Property.   Immediately   upon  the
expiration or earlier termination of this Agreement and if Employee is no longer
employed by Employer,  Employee shall return to Employer any and all property of
Employer, including, but not limited to, all documents,  agreements,  schedules,
statements, customer lists, supplier lists, plans, designs, parts and equipment,
that is in the possession or control (direct or indirect) of Employee.

                  9.   Survival/Remedies/Severability.   Employee   specifically
acknowledges that (a) Employer currently has operating facilities located in the
Restricted  Territory;  (b)  Employer  receives  much of its  business  from and
throughout  the  Restricted  Territory;  (c)  Employer  has plans to expand  its
operations  throughout  the  Restricted   Territory;   and  (d)  the  geographic
restrictions  contained in Section 5 hereof, and the length of time restrictions
in  Sections  5, 6 and 7  hereof  are each  necessary  and  reasonable  and were
negotiated with Employer. The restrictions and obligations set forth in Sections
5, 6, 7 and 8 hereof shall survive the expiration or earlier termination of this
Agreement.  The parties hereby  acknowledge and agree that the  restrictions and
obligations  set  forth in  Sections  5, 6, 7 and 8 hereof  are  reasonable  and
necessary,  and that any  violation  thereof  would  result in  substantial  and
irreparable  injury to  Employer,  and that  Employer  may not have an  adequate
remedy at law with respect to any such violation.  Accordingly,  Employee agrees
that, in
                                        5
<PAGE>
the event of any actual or threatened violation thereof, Employer shall have the
right and  privilege to obtain,  in addition to any other  remedies  that may be
available,  equitable  relief,  including  temporary  and  permanent  injunctive
relief, to cease or prevent any actual or threatened  violation of any provision
hereof.  Each and every  provision set forth in Sections 5, 6, 7 and 8 hereof is
independent and severable from the others,  and no restriction  will be rendered
unenforceable by virtue of the fact that, for any reason, any other or others of
them may be  unenforceable  in whole or in part. If any provision in Sections 5,
6, 7 or 8 hereof is unenforceable for any reason whatsoever, that provision will
be  appropriately  limited  and  reformed  to the  maximum  extent  provided  by
applicable law. If the scope of any restriction contained herein is too broad to
permit  enforcement to its full extent,  then such restriction shall be enforced
to  the  maximum  extent  permitted  by law so as to be  judged  reasonable  and
enforceable,  and the  parties  agree  that  such  scope may be  modified  by an
arbitrator or judge in any proceeding to enforce this Agreement.  This includes,
without  limitation,  altering  or  enforcing  only  portions  of the  limits on
activity   restrictions,   the  geographic   scope,  and  the  duration  of  the
restrictions unless to do so would be contrary to law or public policy.

                  10. Inventions.

                           (a)  Assignment.  Employee  agrees  that  any and all
inventions,   including   any   improvements,    innovations   and   discoveries
(collectively  "Inventions")  that  Employee  conceives,  develops or reduces to
practice, and all copyrightable materials and trademarks  (collectively "Works")
that Employee prepares alone or with others during Employee's term of employment
under  this  Agreement:   (i)  that  relate  to  Employer's   and/or  Employer's
subsidiaries actual or foreseeable business;  (ii) that Employee works on during
Employee's working hours for Employer and/or Employer's  subsidiaries;  or (iii)
for which Employee uses Employer facilities or materials, will be and remain the
sole and exclusive  property of Employer.  Employee hereby  irrevocably  assigns
Employee's  entire  right,  title  and  interest  in and to each  of  Employee's
Inventions and Works to Employer  and/or  Employer's  subsidiaries,  free of any
compensation beyond Employee's compensation as an employee of Employer. Employee
agrees to assist in the  preparation of  applications  for patent or other legal
protection  of  Inventions  and Works in all  countries  of the world,  and will
reasonably  cooperate with Employer in defending the validity or  enforceability
of such protection.  Employee  further agrees to execute all documents  Employer
may from time to time request to perfect the  assignment  of the  Inventions  or
Works throughout the world.

                           (b)  Assignment   after  Expiration  or  Termination.
Employee  agrees  that  any  Inventions  or  Works  that  Employee  asserts  are
conceived,  developed or reduced to practice by Employee,  alone or with others,
within six months immediately following the expiration or earlier termination of
Employee's  employment  hereunder  that  relate  to the  actual  or  foreseeable
business of Employer and/or  Employer's  subsidiaries,  will be presumed to have
been made during the term of Employee's employment and will be the sole property
of  Employer,  unless  Employee  presents  sufficient  evidence  to  Employer to
satisfactorily rebut the presumption.

                  11. Miscellaneous.

                           (a) Notices.  All notices required or permitted to be
given  hereunder shall be in writing and shall be deemed given when delivered in

                           (b) Entire Agreement.  This Agreement constitutes the
entire agreement  between the parties and shall be binding upon and inure to the
benefit  of the  parties  hereto  and their  respective  legal  representatives,
successors and permitted assigns.  Except as set forth herein, the provisions of
this Agreement supersede any and all other agreements or understandings, whether
oral or written,  between  Employer and  Employee,  with  respect to  Employee's
employment by
                                        7
<PAGE>
Employer.  Any amendments,  or alternative or  supplementary  provisions to this
Agreement   must  be  made  in  writing  and  duly  executed  by  an  authorized
representative or agent of each of the parties hereto.

                           (c)  Non-Waiver.  The  failure  in any  one  or  more
instances of a party to insist upon  performance of any of the terms,  covenants
or  conditions  of this  Agreement,  to exercise  any right or privilege in this
Agreement  conferred,  or the  waiver by said  party of any breach of any of the
terms,  covenants or conditions of this  Agreement,  shall not be construed as a
subsequent  waiver  of  any  such  terms,  covenants,   conditions,   rights  or
privileges,  but the same shall  continue and remain in full force and effect as
if no such  forbearance  or waiver had  occurred.  No waiver  shall be effective
unless it is in  writing  and  signed  by an  authorized  representative  of the
waiving party. A breach of any representation, warranty or covenant shall not be
affected  by the  fact  that a more  general  or more  specific  representation,
warranty or covenant was not also breached.

                           (d)  Attorneys'  Fees.  If any  action is  brought to
enforce this Agreement or to collect  damages as a result of a breach of any its
provisions,  the  prevailing  party  shall  also  be  entitled  to  collect  its
reasonable  attorneys'  fees and costs incurred in such action,  which costs can
include the reasonable costs of investigation, expert witnesses and the costs in
enforcing or collecting any judgment rendered,  all as determined and awarded by
the Court.

                           (e)  Counterparts.  This Agreement may be executed in
multiple  count- erparts,  each of which shall be deemed to be an original,  and
all such counterparts shall constitute but one instrument.

                           (f) APPLICABLE  LAW. THIS AGREEMENT SHALL BE GOVERNED
AND CONTROLLED AS TO VALIDITY, ENFORCEMENT, INTERPRETATION, CONSTRUCTION, EFFECT
AND IN ALL  OTHER  RESPECTS  BY THE  INTERNAL  LAWS OF THE  STATE OF  CALIFORNIA
APPLICABLE TO CONTRACTS MADE IN THAT STATE.

                           (g) Construction.  The parties hereto acknowledge and
agree that each party has  participated  in the drafting of this  Agreement  and
that this  document has been  reviewed by the  respective  legal counsel for the
parties hereto and that the normal rule of  construction  to the effect that any
ambiguities  are to be resolved  against the drafting party shall not be applied
to the  interpretation of this Agreement.  No inference in favor of, or against,
any party  shall be drawn from the fact that one party has  drafted  any portion
hereof.


                  EMPLOYEE ACKNOWLEDGES THAT HE HAS READ AND THAT HE UNDERSTANDS
THIS  AGREEMENT,  THAT HE WAS GIVEN A  REASONABLE  OPPORTUNITY  TO  REVIEW  THIS
AGREEMENT  AND  DISCUSS  IT  WITH  THE  ADVISORS  OF HIS  CHOICE,  AND  THAT  HE
UNDERSTANDS THIS AGREEMENT IS A CONDITION OF HIS NEW OR CONTINUED  EMPLOYMENT BY
EMPLOYER.
