This announcement is neither an offer to purchase nor a solicitation of an offer
to sell Shares (as defined below). The Offer (as defined below) is made only by
the Offer to Purchase, dated October 25, 2000, and the related Letter of
Transmittal and any amendments or supplements thereto, and is being made to all
holders of Shares. The Purchaser (as defined below) is not aware of any
jurisdiction where the making of the Offer is prohibited by administrative or
judicial action under any valid state statute. If the Purchaser becomes aware of
any valid state statute prohibiting the making of the Offer or the acceptance of
Shares pursuant thereto, the Purchaser will make a good faith effort to comply
with such statute or seek to have such statute declared inapplicable to the
Offer. If, after such good faith effort, the Purchaser cannot comply with such
state statute, the Offer will not be made to (nor will tenders be accepted from
or on behalf of) the holders of Shares in such state. In those jurisdictions
where securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer shall be deemed to be made on behalf of the
Purchaser by one or more registered brokers or dealers licensed under the laws
of such jurisdiction.

associated rights to purchase Series A Junior Participating Preferred Stock (the
"Rights" and collectively with the Common Stock, the "Shares") of Cerprobe

Share net to the seller in cash (the "Offer Price"), upon the terms and subject
to the conditions set forth in the Offer to Purchase, dated October 25, 2000
(the "Offer to Purchase"), and in the related Letter of Transmittal (which,
together with any amendments or supplements thereto, collectively constitute the
"Offer"). Tendering stockholders who are the record holder of their Shares and

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY
TIME, ON TUESDAY, NOVEMBER 21, 2000 UNLESS THE OFFER IS EXTENDED.




THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE HAVING BEEN VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A NUMBER OF
SHARES REPRESENTING AT LEAST A MAJORITY OF THE OUTSTANDING SHARES, AND (II) THE
APPLICABLE WAITING PERIOD UNDER THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT
OF 1976, AS AMENDED, HAVING EXPIRED OR BEEN TERMINATED PRIOR TO THE EXPIRATION
OF THE OFFER. THE OFFER IS ALSO SUBJECT TO CERTAIN OTHER CONDITIONS. SEE SECTION
13 OF THE OFFER TO PURCHASE.

The Offer is being made under an Agreement and Plan of Merger, dated as of
October 11, 2000 (the "Merger Agreement"), among the Purchaser, Parent and the
Company. Pursuant to the Merger Agreement, as soon as practicable after the
purchase of Shares in the Offer and the satisfaction or waiver (subject to
applicable law) of the conditions set forth in the Merger Agreement, the
Purchaser will be merged with and into the Company (the "Merger") in accordance
with the applicable provisions of the Delaware General Corporation Law (the
"DGCL"). At the effective time of the Merger, each issued and outstanding Share
(other than Shares held by Parent or any subsidiary of Parent or held in
treasury by the Company or any subsidiary of the Company and Shares held by
stockholders who have demanded and perfected appraisal rights under the DGCL)
will be converted into and represent the right to receive an amount equal to the
Offer Price or any higher price which may be paid for the Shares under the
Offer, without interest. If the Purchaser acquires 90% or more of the
outstanding Shares in the Offer, the Purchaser will effect the Merger as a
"short-form" merger under the DGCL, without a vote of the stockholders of the
Company. See "Purpose Of The Offer; Plans For The Company; The Merger--The
Merger Agreement," in the Offer to Purchase.

Parent has also entered into Affiliate Tender Agreements, each dated as of
October 11, 2000 (collectively, the "Affiliate Tender Agreements"), with certain
stockholders of the Company. Under the terms of the Affiliate Tender Agreements,
those stockholders have, among other things, agreed to tender their Shares into
the Offer (which Shares currently represent in the aggregate approximately 9.8%
of the outstanding Shares, excluding Shares issuable upon exercise of
outstanding options). Parent and the Company have also entered into a Stock
Option Agreement, dated as of October 11, 2000, under which the Company has
granted Parent an irrevocable option, exercisable in certain circumstances
following termination of the Merger Agreement, to purchase from the Company upon
original issue from time to time up to a number of Shares equal to 19.9% of the
number of Shares outstanding on October 11, 2000, subject to adjustment, at an
initial exercise price of $20.00 per Share. See "Purpose Of The Offer; Plans For
The Company; The Merger--The Affiliate Tender Agreements" and "--The Stock
Option Agreement" in the Offer to Purchase.

The Board of Directors of the Company has, by unanimous vote, (A) determined
that the terms of the Offer and the Merger are fair to, and in the best interest
of, the stockholders of the Company, (B) approved the Offer, the Merger, the
Merger Agreement and the other transactions contemplated by the Merger
Agreement, and (C) recommended that the Company's stockholders accept the Offer
and tender their Shares in the Offer.

For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not properly
withdrawn as, if and when the Purchaser gives oral or written notice to the
Depositary, as agent for tendering stockholders, of the Purchaser's acceptance
for payment of such Shares pursuant to the Offer. Upon the terms and subject to
the conditions of the Offer, payment for Shares accepted for payment pursuant to
the Offer will be made by deposit of the aggregate Offer Price with the
Depositary, which will act as agent for tendering stockholders for the purpose
of receiving payment from the Purchaser and transmitting such payment to
tendering stockholders. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE
OFFER PRICE, REGARDLESS OF ANY EXTENSIONS OF THE OFFER OR ANY DELAY IN MAKING
SUCH PAYMENT. Payment for Shares tendered and accepted for payment pursuant to
the Offer will be made only after timely receipt by the Depositary of (i)
certificates for such Shares or timely confirmation of a book-entry transfer of
such Shares into the Depositary's account at the Book-Entry Transfer Facility
(as defined in the Offer to Purchase) pursuant to the procedures set forth in
the Offer to Purchase, (ii) the Letter of Transmittal (or a facsimile thereof)
properly completed and duly executed, with any required signature guarantees or,
in the case of a book-entry transfer, an Agent's Message (as defined in the
Offer to Purchase) and (iii) any other documents required by the Letter of
Transmittal.


Any stockholder who desires to tender Shares and whose certificates evidencing
such Shares are not immediately available, or who cannot comply with the
procedures for book-entry transfer described in the Offer to Purchase on a
timely basis, or who cannot deliver the certificates and all required documents
to the Depositary prior to the expiration of the Offer, may tender such Shares
by following the procedures for guaranteed delivery set forth in Section 3 in
the Offer to Purchase.

Shares tendered into the Offer may be withdrawn at any time prior to the
expiration of the Offer and, unless theretofore accepted for payment under to
the Offer, may also be withdrawn at any time after December 24, 2000. The term
"Expiration Date" means 12:00 midnight, New York City time, on Tuesday, November
21, 2000, unless the Purchaser, in its sole discretion (subject to the terms of
the Merger Agreement), shall have extended the period of time during which the
Offer is open, in which event the term "Expiration Date" shall mean the latest
time and date on which the Offer, as so extended by the Purchaser, shall expire.

Subject to the terms of the Merger Agreement and applicable rules and
regulations of the Securities and Exchange Commission, the Purchaser expressly
reserves the right, in its sole discretion, at any time or from time to time, to
(a) extend the period of time during which the Offer is open and thereby delay
acceptance for payment of and the payment for any Shares, by giving oral or
written notice of such extension to the Depositary and (b) amend the Offer in
any other respect by giving oral or written notice of such amendment to the
Depositary. Any extension, delay, waiver, amendment or termination of the Offer
will be followed as promptly as practicable by public announcement, which in the
case of an extension will be issued no later than 9:00 a.m., New York City time,
on the next business day after the previously scheduled Expiration Date.

Tenders of Shares made pursuant to the Offer are irrevocable, except that Shares
tendered pursuant to the Offer may be withdrawn as described above and in the
Offer to Purchase. For a withdrawal of Shares to be effective, a written,
telegraphic, telex, or facsimile transmission notice of withdrawal must be
timely received by the Depositary at one of its addresses set forth on the back
cover of the Offer to Purchase. Any such notice of withdrawal must specify the
name of the person having tendered the Shares to be withdrawn, the number of
Shares to be withdrawn and the names in which the certificate(s) evidencing the
Shares to be withdrawn are registered, if different from that of the person who
tendered such Shares. The signature(s) on the notice of withdrawal must be
guaranteed by an Eligible Institution (as defined in the Offer to Purchase),
unless such Shares have been tendered for the account of an Eligible
Institution. If Shares have been tendered under the procedures for book-entry
tender as set forth in Section 3 of the Offer to Purchase, any notice of
withdrawal must specify the name and number of the account at the Book-Entry
Transfer Facility to be credited with the withdrawn Shares. If certificates for
the Shares to be withdrawn have been delivered or otherwise identified to the
Depositary, the name of the registered holder and the serial numbers of the
particular certificates evidencing the Shares to be withdrawn must also be
furnished to the Depositary as aforesaid before the physical release of such
certificates.


All questions as to the form and validity (including time of receipt) of any
notices of withdrawal will be determined by the Purchaser in its sole
discretion, which determination will be final and binding.

Sales of the Shares under the Offer will be taxable transactions for Federal
income tax purposes and may also be taxable under applicable state, local and
other tax laws. For Federal income tax purposes, a stockholder whose Shares are
purchased under the Offer or who receives cash as a result of the Merger will
realize gain or loss equal to the difference between the adjusted basis of the
Shares sold or exchanged and the amount of cash received therefor. Such gain or
loss will be capital gain or loss if the Shares were held as capital assets by
the stockholder and will be long-term if the Shares have been held for more than
12 months. Long-term capital gain of a non-corporate stockholder is generally
subject to a maximum federal income tax rate of 20%. All stockholders should
consult their own tax advisors with respect to the specific tax consequences to
them of the Offer and the Merger, including the application and effect of
Federal, state, local, foreign, and other tax laws. For a more complete
description of certain U.S. Federal income tax consequences of the Offer and the
Merger, see Section 5 of the Offer to Purchase.

Under the Merger Agreement and pursuant to Rule 14d-11 of the General Rules and
Regulations under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), the Purchaser may, subject to certain conditions, include a subsequent
offering period following the Expiration Date. The Purchaser does not currently
intend to include a subsequent offering period in the Offer, although it
reserves the right to do so in its sole discretion. In the event the Purchaser
provides a subsequent offering period, withdrawal rights will not apply to
Shares tendered during such subsequent offering period and withdrawal rights
will not apply during such subsequent offering period with respect to Shares
tendered in the Offer and accepted for payment. See Section 1 of the Offer to
Purchase.

The information required to be disclosed by Paragraph (d)(1) of Rule 14d-6 of
the General Rules and Regulations under the Exchange Act is contained in the
Offer to Purchase and is incorporated herein by reference.
