THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK
CITY TIME, ON FRIDAY, JUNE 22, 2001, UNLESS EXTENDED.

     Vishay Intertechnology, Inc., through its wholly-owned subsidiary Vishay
TEMIC Semiconductor Acquisition Holdings Corp., hereby offers, upon the terms
and subject to the conditions set forth in this document and in the enclosed
letter of transmittal, to exchange 1.5 shares of Vishay common stock for each
outstanding share of common stock of Siliconix incorporated which is validly
tendered and not properly withdrawn on or prior to the expiration date of the
offer.

     Vishay, through Vishay TEMIC, currently owns approximately 80.4% of the
outstanding shares of Siliconix common stock. This offer is conditioned on the
tender of at least a majority of the outstanding Siliconix shares that Vishay
does not already own. We will not waive this condition in the offer.

     Our obligation to exchange shares of Vishay common stock for shares of
Siliconix common stock is also subject to the other conditions listed under
"Conditions of the Offer."

     If this offer is consummated, we will own more than 90% of the outstanding
common stock of Siliconix. As soon as possible after consummation of the offer,
we currently intend to effect a short-form merger of Siliconix with a subsidiary
of Vishay, although we are not required to do so. If such a merger takes place
and you have not validly tendered your shares of Siliconix common stock in the
offer, your shares will be exchanged for the same consideration per Siliconix
share you own that you would have received, without interest, if you had
tendered your shares in the offer, unless you properly perfect your appraisal
rights under Delaware law. See "Purpose of the Offer; The Merger; Appraisal
Rights."

     Vishay's common stock is listed on the New York Stock Exchange under the
symbol "VSH." Siliconix's common stock is quoted on the Nasdaq National Market
under the symbol "SILI."


     SEE "RISK FACTORS" BEGINNING ON PAGE 10 FOR A DISCUSSION OF ISSUES THAT YOU
SHOULD CONSIDER WITH RESPECT TO THE OFFER AND THE MERGER.


     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved the Vishay common stock to be issued in
the offer and the merger or determined if this prospectus is truthful or
complete. Any representation to the contrary is a criminal offense.


                 The date of this prospectus is June 21, 2001.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER

Q. WHY IS VISHAY MAKING THIS OFFER?

A. Vishay, through Vishay TEMIC, currently owns approximately 80.4% of the
   outstanding Siliconix common stock. Our purpose in making the offer is to
   acquire all of the Siliconix shares that we do not already own. Our offer is
   conditioned on there being tendered a majority of the publicly held Siliconix
   shares. If that condition is satisfied and if the offer is consummated, we
   will own more than 90% of the Siliconix shares. As soon as practicable after
   the conclusion of the offer, we currently intend to effect a short-form
   merger of Siliconix with a subsidiary of Vishay, with the surviving company
   being a wholly-owned subsidiary of Vishay.

Q. WHAT WILL I RECEIVE IN EXCHANGE FOR MY SILICONIX SHARES IN THE OFFER?

A. You will be entitled to receive 1.5 shares of Vishay common stock in exchange
   for each share of Siliconix common stock that you validly tender in the
   offer. No fractional shares of Vishay common stock will be issued in the
   offer. Instead, any stockholder entitled to receive a fractional Vishay share
   will get cash in an amount equal to the fraction multiplied by the closing
   price of a Vishay share on the NYSE on the day the offer expires.

Q. IF I DECIDE NOT TO TENDER, HOW WILL THE OFFER AFFECT MY SILICONIX SHARES?

A. If you decide not to tender your shares in the offer and the offer is
   consummated and the short-form merger takes place, you will receive in the
   merger the same consideration per Siliconix share you own that you would have
   received, without interest, if you had tendered your shares in the offer,
   unless you properly perfect your appraisal rights under Delaware law.
   Although it is our current intention to effect the short-form merger, we are
   not required to do so. We would not effect the short-form merger if prevented
   from doing so by a court or, if in our judgment, it was advisable not to do
   so in order to settle litigation or avoid litigation risks. See "Purpose of
   the Offer; The Merger; Appraisal Rights" beginning on page 41.

Q. HOW LONG WILL IT TAKE TO COMPLETE THE OFFER AND THE MERGER?

A. We hope to complete the offer following its scheduled expiration on June 22,
   2001. However, we may extend the offer if the conditions to the offer have
   not been satisfied at the scheduled expiration date or if we are required to
   extend by the rules of the SEC. We currently intend to complete the merger
   shortly after the consummation of the offer.

Q. HAS THE SILICONIX BOARD MADE A RECOMMENDATION CONCERNING THE OFFER?


A. As set forth in Siliconix's solicitation/recommendation statement filed with
   the SEC on June 8, 2001, the Siliconix board and the special committee of the
   Siliconix board are taking no position with respect to the offer and the
   merger.


Q. WHY HAS THE SILICONIX BOARD FORMED A SPECIAL COMMITTEE IN CONNECTION WITH
   VISHAY'S PROPOSAL TO ACQUIRE ALL OF SILICONIX?

A. Vishay owns approximately 80.4% of Siliconix's outstanding common stock. Four
   members of Siliconix's board of directors are employees or consultants of
   Vishay. King Owyang, Siliconix's president and chief executive officer, holds
   options to purchase 102,500 shares of Vishay common stock. Because of these
   significant conflicts of interest, after the board of directors of Siliconix
   was advised that Vishay had an interest in acquiring the shares of Siliconix
   that it did not already own, the Siliconix board established a special
   committee consisting of directors who were not then affiliated with Siliconix
   or Vishay, other than as Siliconix directors, and who held no management
   positions with Siliconix. The special committee retained its own counsel and
   investment advisor and was authorized to negotiate with Vishay concerning
   Vishay's initial proposal, to evaluate the proposal and to make a
   recommendation to the Siliconix stockholders. See "Background of the Offer"
   beginning on page 25. You should be aware, however, that members of the
   special committee have had prior business relationships with Vishay.

    To find out more information about the conflicts of interest that exist
    between Vishay, the Siliconix board of directors and the special committee,
    please refer to "Interests of Certain Persons" on page 48.

Q. HAS THERE BEEN ANY OBJECTION BY SILICONIX STOCKHOLDERS TO VISHAY'S PROPOSAL
   TO ACQUIRE THE PUBLICLY HELD SHARES OF SILICONIX?

A. Yes. A number of class action lawsuits were filed in Delaware and California
   after Vishay announced its initial proposal to acquire the publicly held
   shares of Siliconix. These lawsuits allege, among other things, a breach of
   fiduciary duty by Vishay, Siliconix and certain members of the boards of
   directors of Vishay and Siliconix and the existence of conflicts of interest
   of members of the special committee. See "Certain Litigation" on page 29 for
   a more detailed discussion of these lawsuits. It is a condition to the offer
   that there be no litigation relating to the offer or the merger at the time
   shares are accepted for exchange, but we can waive this condition.

Q. WHAT PERCENTAGE OF VISHAY COMMON STOCK WILL SILICONIX STOCKHOLDERS OWN AFTER
   THE OFFER AND THE MERGER?


A. Immediately after consummation of the offer and the merger, we anticipate
   that the former public stockholders of Siliconix will hold approximately 6.0%
   of the outstanding shares of Vishay, including for this purpose Vishay's
   Class B common stock. This assumes 122,429,597 shares of Vishay common stock
   and 15,506,634 shares of Vishay Class B common stock outstanding before
   giving effect to the consummation of the offer and the merger, that 8,773,560
   shares of Vishay common stock will be issued in the offer and the merger and
   that no stockholders exercise appraisal rights.


    The holders of Vishay common stock are entitled to one vote for each share
    held, while the holders of Class B common stock are entitled to 10 votes for
    each share held. The former public stockholders of Siliconix, who are
    receiving common stock, will hold approximately 3.1% of the outstanding
    voting power of Vishay immediately following the offer and the merger. See
    "Risk Factors -- The holders of Class B common stock have voting control of
    Vishay" on page 15.

Q. WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE OFFER?

A. The offer is subject to several conditions, including:

    - at least a majority of the outstanding Siliconix common stock not held by
      Vishay or its subsidiaries having been validly tendered and not properly
      withdrawn;

    - the registration statement of which this prospectus is a part having been
      declared effective by the SEC;

    - the shares of Vishay common stock to be issued in the offer having been
      approved for listing on the NYSE;

    - the tax opinion of Kramer Levin Naftalis & Frankel LLP, filed as an
      exhibit to the registration statement, not having been withdrawn;

    - there not having occurred any other event that would reasonably be
      expected to have a material adverse effect on Siliconix;

    - the absence of certain legal impediments to the offer or the merger; and

    - the absence of certain litigation or other legal action by or before any
      court or governmental authority.

    The minimum condition, the registration statement effectiveness condition
    and the listing condition will not be waived in this offer. These conditions

Q. HOW DO I PARTICIPATE IN YOUR OFFER?

A. To tender your shares, you should do the following:

    - If you hold shares in your own name, complete and sign the enclosed letter
      of transmittal and return it with your share certificates to American

                                        4
   10

      for the offer, at the appropriate address specified on the back cover page
      of this prospectus before the expiration date of the offer.

    - If you hold your shares in "street name" through a broker or other
      nominee, instruct your nominee to tender your shares before the expiration
      date.

    Alternatively, you may comply with the guaranteed delivery procedures set
    forth in "Guaranteed Delivery" beginning on page 38. For more information on
    the timing of the offer, extensions of the offer period and your rights to
    withdraw your shares from the offer before the expiration date, please refer
    to "The Offer" beginning on page 35.

Q. WILL I BE TAXED ON THE VISHAY COMMON STOCK THAT I RECEIVE?

A. Your receipt of the Vishay common stock will generally be tax-free for United
   States federal income tax purposes. However, you may be subject to taxes for
   any cash received in lieu of a fraction of a share of Vishay common stock.

Q. WILL I HAVE TO PAY ANY FEES OR COMMISSIONS?

A. If you are the record owner of your Siliconix shares and you tender your
   shares directly to the exchange agent, you will not have to pay brokerage
   fees or incur similar expenses. If you own your shares through a broker or
   other nominee, and your broker tenders the shares on your behalf, your broker
   may charge you a fee for doing so. You should consult your broker or other
   nominee to determine whether any charges will apply.

Q. DO THE STATEMENTS ON THE COVER PAGE REGARDING THIS PROSPECTUS BEING SUBJECT
   TO CHANGE AND THE REGISTRATION STATEMENT FILED WITH THE SEC NOT YET BEING
   EFFECTIVE MEAN THAT THE OFFER HAS NOT COMMENCED?

A. No. Effectiveness of the registration statement is not necessary for the
   offer to commence. Last year, the SEC changed its rules to permit exchange
   offers to begin before the related registration statement has become
   effective, and we are taking advantage of the rule changes. We cannot,
   however, accept for exchange any shares tendered in the offer until the
   registration statement is declared effective by the SEC and the other
   conditions to our offer have been satisfied or, where permissible, waived.

Q. ARE VISHAY'S BUSINESS, PROSPECTS AND FINANCIAL CONDITION RELEVANT TO MY
   DECISION TO TENDER MY SHARES IN THE OFFER?

A. Yes. Shares of Siliconix accepted in the offer will be exchanged for Vishay
   common stock and so you should consider Vishay's business, prospects and
   financial condition before you decide to tender your shares in the offer. In
   considering Vishay's business, prospects and financial condition, you should
   review the documents incorporated by reference in this prospectus because
   they contain detailed business, financial and other information about us.

     This summary highlights selected information from this document and does
not contain all of the information that is important to you. To better
understand the offer and the short-form merger and for a more complete
description of the legal terms of the offer and the merger, you should read
carefully this entire document and the documents to which you have been
referred. See "Where You Can Find More Information" beginning on page 1.

                                  INTRODUCTION

     We propose to acquire all the shares of common stock of Siliconix that we
do not own. Currently, Vishay owns approximately 80.4% of Siliconix's
outstanding shares. We are offering to exchange 1.5 shares of Vishay common
stock for each outstanding share of Siliconix common stock validly tendered and
not properly withdrawn in the offer. We will not accept any Siliconix shares for
exchange in the offer unless the shares tendered constitute at least a majority
of the publicly held shares. There are also other conditions to the offer.

     We currently intend to merge Siliconix with a wholly-owned subsidiary of
Vishay promptly after the consummation of the offer, by way of a short-form
merger under Delaware law. Each share of Siliconix common stock which has not
been exchanged or accepted for exchange in the offer would be converted in the
merger into the same consideration per Siliconix share as is exchanged in the
offer.

                              THE OFFER (PAGE 35)

EXCHANGE OF SILICONIX SHARES; DELIVERY OF VISHAY COMMON STOCK


     Upon the terms and subject to the conditions of the offer, we will accept
for exchange, and will exchange, Siliconix shares validly tendered and not
properly withdrawn as promptly as practicable after the expiration date of our
offer.


TIMING OF THE OFFER


     Our offer is currently scheduled to expire on Friday, June 22, 2001;
however, we may extend our offer from time to time as necessary until all the
conditions to the offer have been satisfied or, where permissible, waived. For
further details, see "Extension, Termination and Amendment" beginning on page
35.


EXTENSION, TERMINATION AND AMENDMENT

     We reserve the right, in our sole discretion, at any time or from time to
time to extend the period of time during which our offer remains open, and we
can do so by giving oral or written notice of such extension to the exchange
agent. If we decide to extend our offer, we will make an announcement to that
effect no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled expiration date. We are not making any assurance
that we will exercise our right to extend our offer, although we currently
intend to do so until all conditions have been satisfied or, where permissible,
waived. During any such extension, all Siliconix shares previously tendered and
not withdrawn will remain subject to the offer, subject to your right to
withdraw your Siliconix shares prior to the expiration date of the offer.

     We reserve the right to increase or decrease the exchange ratio or to make
any other changes in the terms and conditions of the offer. However, in no event
will we consummate the offer unless the registration statement has been declared
effective, the Vishay shares issuable in the offer have been listed on the NYSE
and at least a majority of the publicly held shares of Siliconix have been
validly tendered for exchange and not properly withdrawn.

     Any increase or decrease in the exchange ratio or extension, termination,
other amendment or delay of the offer will be made by giving written or oral
notice to the exchange agent. We will follow any extension, termination,
amendment or delay, as promptly as practicable, with a public announcement. In
the case of an extension, any such announcement 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. Subject to applicable law (including Rules 14d-4(c)
and 14d-6(d) under the Exchange Act, which require that any material change in
the information published, sent or given to stockholders in connection with the
offer be promptly sent to stockholders in a manner reasonably designed to inform
stockholders of such change) and without limiting the manner in which we may
choose to make any public announcement, we assume no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
making a release to the Dow Jones News Service.

WITHDRAWAL RIGHTS

     Siliconix shares tendered pursuant to the offer may be withdrawn at any
time prior to the expiration date of the offer.

PROCEDURE FOR TENDERING SHARES

     The method of tendering your shares in the offer will depend on whether the
shares are held in certificate or book-entry form.

     - If your shares are held in certificate form, you must deliver the
       certificates, a properly completed and duly executed letter of
       transmittal, or a manually executed facsimile of that document, and any
       other required documents to the exchange agent at one of its addresses
       set forth on the back cover

                                        8
   14

       of this prospectus. In the circumstances detailed in the letter of
       transmittal, the signatures on the letter of transmittal must be
       guaranteed.

     - If your Siliconix shares are held in book-entry form, the shares must be
       tendered in accordance with the procedures for book-entry tender, and the
       exchange agent must receive a so-called "agent's message" and a
       confirmation of receipt of the tender. The procedures for book-entry
       transfer are described under "Procedure for Tendering Shares" beginning
       on page 37.

     In all cases, deliveries must be made prior to the expiration of the offer.

     If your shares are not currently available and you cannot now comply with
the preceding requirements, you can still participate in the offer by complying
with the guaranteed delivery procedures set forth under "Guaranteed Delivery"
beginning on page 38.

APPRAISAL RIGHTS

     Under Delaware law, you will not have any appraisal rights in connection
with the offer. However, appraisal rights are available in connection with the
short-form merger. For a detailed discussion of these appraisal rights, see
"Purpose of the Offer; The Merger; Appraisal Rights" beginning on page 41.

ACCOUNTING TREATMENT

     The merger will be accounted for at historical costs, with the exception of
the Siliconix minority interest acquired in the offer, and the merger which will
be accounted for under the purchase method of accounting in accordance with
United States generally accepted accounting principles. Accordingly, the cost to
acquire the Siliconix minority interest in excess of its carrying value will be
allocated on a pro rata basis to the assets acquired and liabilities assumed
based on their fair values, with any excess being allocated to goodwill.

     The acquisition of the Siliconix common stock would not be considered
material to Vishay and, accordingly, Vishay is not required to include pro forma
financial information in this prospectus, except as provided in "Comparative Per
Share Information" on page 21.


           POSITION OF THE BOARD OF DIRECTORS OF SILICONIX (PAGE 31)



     The Siliconix board of directors and the special committee have determined
to remain neutral and make no recommendation with respect to the offer and the
merger.


                             RISK FACTORS (PAGE 11)

     In deciding whether to tender your shares pursuant to the offer, you should
read carefully this prospectus and the documents to which we refer you. You
should carefully take into account the following risk factors:

     - the market value of Vishay common stock at the time you tender may be
       different than at the time you receive your Vishay shares in the offer
       and the merger; the exchange ratio for the offer will not be adjusted
       based upon changes in the market price of Vishay stock;

     - the price of Vishay common stock could depend upon factors different than
       those affecting the price of Siliconix common stock; the price of Vishay
       common stock could decline following the offer;

     - there are risks associated with integrating Siliconix into Vishay,
       including the risk that the anticipated benefits of the business
       combination may not be fully realized; and

     - there are general risks associated with Vishay's business, including
       competition, its ability to respond to technological change and the
       current softness in the electronic component industry.

     See "Risk Factors" beginning on page 11 for a more complete discussion of
these and other risk factors.

        OTHER FACTORS TO CONSIDER BEFORE TENDERING YOUR SHARES (PAGE 32)

     In addition to the risk factors, there are a variety of other factors that
you should consider in determining whether to tender your shares in the offer.
Among these are the anticipated competitive advantages that a fully combined
entity could have and the larger trading volume and analyst coverage of the
Vishay common stock over the Siliconix common stock. You should also consider
Siliconix's positive historical business performance, its historical stock price
in relation to its earnings and Siliconix's other business strengths and
innovative traditions from which you will benefit only indirectly as a
stockholder of Vishay. See "Other Factors to Consider Before Tendering Your
Shares" beginning on page 32 and "Relationships with Siliconix" beginning on
page 46.

   16

                                  RISK FACTORS

     In deciding whether to tender your shares pursuant to the offer, you should
read carefully this prospectus and the documents to which we refer you. You
should also carefully consider the following factors:

  RISKS RELATED TO THE OFFER AND THE MERGER

THE NUMBER OF VISHAY SHARES THAT YOU RECEIVE IN THE OFFER WILL BE BASED UPON A
FIXED EXCHANGE RATIO. THE VALUE OF THE VISHAY SHARES AT THE TIME YOU RECEIVE
THEM COULD BE LESS THAN AT THE TIME YOU TENDER YOUR SILICONIX SHARES.

     In the offer, each Siliconix share will be exchanged for 1.5 Vishay shares.
This is a fixed exchange ratio. The offer does not provide for an adjustment in
the exchange ratio even if there is a decrease in the market price of the Vishay
common stock between the date of this prospectus and the expiration date of the
offer. The market price of the Vishay common stock will likely be different on
the date of the expiration of the offer than it is today because of changes in
the business, operations or prospects of Vishay, market reactions to this offer,
possible other Vishay acquisitions, issuances by Vishay of equity or debt
securities, general market and economic conditions and other factors. Tendering
stockholders of Siliconix are urged to obtain current market quotations for the
Vishay common stock and the Siliconix common stock. See "Conditions of the
Offer" beginning on page 43 and "Comparative Per Share Prices" on page 23.

BENEFITS OF THE COMBINATION MAY NOT BE REALIZED.

     If we consummate the offer and the contemplated short-form merger, we will
integrate two separate companies whose operations have until now been integrated
in only limited ways. The successful combination of Vishay and Siliconix will
require, among other things, integration of Vishay's and Siliconix's sales and
marketing programs, their information and software systems, their employee
retention, hiring and training programs, and their research and development
efforts. The consolidation of business functions, the integration of
departments, systems and procedures, and relocation of staff may present
management challenges. We may not be able to fully integrate the operations of
Siliconix with our operations without encountering difficulties. The integration
may not be completed as rapidly as we expect or achieve anticipated benefits.
Also, management's attention may be diverted by the integration effort, which
could adversely affect the combined company's businesses.

WE MAY INCUR INTEGRATION AND RESTRUCTURING COSTS.

     If the offer and the merger are consummated, we may incur significant
charges as a result of rationalizing and integrating operations. These costs may
include severance and related employee benefit costs and other restructuring
costs, among others.

THE TRADING PRICE OF VISHAY COMMON STOCK MAY BE AFFECTED BY FACTORS DIFFERENT
FROM THOSE AFFECTING THE PRICE OF SILICONIX COMMON STOCK. THE PRICE OF VISHAY
COMMON STOCK COULD DECLINE FOLLOWING THE OFFER.

     Upon consummation of the offer and the merger, holders of Siliconix common
stock will become holders of Vishay common stock. Vishay's business differs from
that of Siliconix, and Vishay's results of operations and business, as well as
the trading price of Vishay common stock, may be affected by factors different
from those affecting Siliconix's results of operations and business and the
price of Siliconix common stock. The price of Vishay common stock may decrease
after shares are accepted for exchange in the offer or after the merger is
consummated.

OFFICERS AND DIRECTORS OF SILICONIX HAVE POTENTIAL CONFLICTS OF INTEREST IN THE
OFFER.


     On June 8, 2001, Siliconix filed with the SEC a solicitation/recommendation
statement, in which it disclosed that the Siliconix board and the special
committee have determined to remain neutral regarding


                                        11
   17


the offer and the merger. In evaluating the Siliconix position, you should be
aware that there exist conflicts of interest among members of the Siliconix
board. Not only does Vishay own approximately 80.4% of the outstanding Siliconix
stock, but four of the seven members of the Siliconix board have affiliations
with Vishay and King Owyang, president and chief executive officer of Siliconix,
holds options to purchase Vishay stock. For this reason, the board of Siliconix
designated a special committee of its directors to consider, evaluate and make a
recommendation concerning Vishay's initial proposal to acquire all of Siliconix.
Members of the special committee have no present relationships with Vishay, but
in the past, they have had significant ties to Vishay. See "Interests of Certain
Persons" on page 48.


  RISKS RELATED TO VISHAY'S BUSINESS GENERALLY

VISHAY'S BUSINESS IS CYCLICAL AND CURRENT SOFTNESS IN THE ELECTRONIC COMPONENT
INDUSTRY MAY CONTINUE AND MAY BECOME MORE PRONOUNCED.

     Vishay and others in the electronic and semiconductor component industry
have recently experienced softness in product demand on a global basis,
resulting in order cancellations and deferrals. This softness is primarily
attributable to a slowing of growth in the personal computer and cell phone
product markets. This slowdown may continue and may become more pronounced. Such
a slowdown in demand, as well as recessionary trends in the global economy in
general or in specific countries or regions where we sell the bulk of our
products, such as the U.S., Germany, France or the Pacific Rim, makes it more
difficult for us to predict our future sales, which also makes it more difficult
to manage our operations, and could adversely impact our results of operations.
In the past, adverse economic trends that resulted in a slowdown in demand for
electronic components materially and adversely impacted Vishay's results of
operations. A decrease in the current demand for Vishay's products or an
increase in supply due to the expansion of production capacity by Vishay's
competitors could cause a significant drop in average sales prices, which could,
in turn, cause a reduction in Vishay's gross margins and operating profits. In
addition, at the initial stage of a business cycle increased efforts by
distributors to sell inventory remaining from the prior cycle may cause average
selling prices to decrease. Vishay's published first quarter 2001 operating
results and those of its competitors can be viewed as being reflective of these
industry trends. Although both Vishay and Siliconix operate in the electronic
components industry, their businesses differ and the effects of the current
slowdown on their operations and prospects may not be the same.

TO REMAIN SUCCESSFUL, VISHAY MUST CONTINUE TO INNOVATE.

     Vishay's future operating results are dependent on its ability to
continually develop, introduce and market new and innovative products, to modify
existing products to respond to technological change and to customize certain
products to meet customer requirements. There are numerous risks inherent in
this process, including the risks that Vishay will be unable to anticipate the
direction of technological change or that Vishay will be unable to develop and
market new products and applications in a timely fashion to satisfy customer
demands. If this occurs, Vishay could lose customers and experience adverse
effects on its financial condition, results of operation and prospects.
Siliconix has had a history of successful product innovation, including in the
past year.

IN THE PAST VISHAY HAS GROWN THROUGH ACQUISITIONS BUT THIS MAY NOT CONTINUE.

     Vishay's long-term historical growth in revenues and net earnings has
resulted in large part from its strategy of expansion through acquisitions.
However, we cannot assure you that Vishay will identify or succeed in
consummating transactions with suitable acquisition candidates in the future.
From time to time, when Vishay is in the process of pursuing a strategic
acquisition, Vishay or the acquisition target may feel compelled in order to
comply with applicable law or for other reasons to announce the potential
acquisition or Vishay's desire to enter into a certain market prior to the
parties' entering into formal agreements. If an acquisition is announced and
then not consummated, Vishay's credibility in the financial markets could
suffer.

                                        12
   18

     If Vishay were to undertake a substantial acquisition for cash, the
acquisition would likely need to be financed in part through bank borrowings or
the issuance of public or private debt. This would decrease Vishay's ratio of
earnings to fixed charges and adversely affect other leverage criteria. Under
our existing credit facility we are required to secure any borrowings by pledges
of our stock interest in, and obtain certain guarantees from, certain of our
significant subsidiaries. In addition, this credit facility restricts us from
paying cash dividends on our capital stock, requires us to comply with other
covenants including the application of specific financial ratios and requires us
to obtain the lenders' consent for certain additional debt financing. We cannot
assure you that the necessary acquisition financing would be available to Vishay
when required on acceptable terms. If Vishay were to undertake an acquisition
for equity, the acquisition may have a dilutive effect on the interests of the
holders of Vishay common stock.

VISHAY'S RESULTS ARE SENSITIVE TO RAW MATERIAL AVAILABILITY, QUALITY AND COST.

     Many of Vishay's products require the use of raw materials which are
produced in only a limited number of regions around the world or are available
from only a limited number of suppliers. Vishay's results of operations may be
adversely affected if Vishay has difficulty obtaining these raw materials, the
quality of available raw materials deteriorates or there are significant price
increases for these raw materials. For example, the prices for tantalum and
palladium, two raw materials we use in our capacitors, are subject to
fluctuation. For periods in which the prices of these raw materials are rising,
we may be unable to pass on the increased cost to our customers and thereby
experience decreased margins for the products in which they are used. For
periods in which the prices are declining, we may be required to write down our
inventory carrying cost of these raw materials which, depending on the extent of
the difference between market price and our carrying cost, could have a material
adverse effect on our net earnings. In addition, from time to time there have
been short-term market shortages of these raw materials. While these shortages
have not historically adversely affected our ability to increase production of
products containing these raw materials, they have historically resulted in
higher raw material costs for us. We cannot assure that any such market
shortages in the future would not adversely affect our ability to increase
production, particularly during periods of growing demand for our products.

     Vishay is a major consumer of the world's annual production of tantalum, a
material used in the manufacture of tantalum capacitors. There are currently
three major suppliers that process tantalum ore into capacitor grade tantalum
powder. Vishay believes that in the long term there exist sufficient tantalum
ore reserves and a sufficient number of tantalum processors to satisfy demand.
The market prices of tantalum ore are currently declining. Depending on the
extent of this trend, we could be required to write down the carrying cost of
our inventory of tantalum ore, which could have a material adverse effect on our
net earnings.

     Palladium, a metal used to produce multi-layer ceramic capacitors, is
currently found primarily in South Africa and Russia. Palladium is a commodity
product that is subject to price volatility. The price of palladium fluctuated
in the range of approximately $201 to $970 per troy ounce during the three years
ended December 31, 2000. Since that time, the price of palladium has been as
high as $1,110 per troy ounce and as of May 25, 2001, it was approximately $660
per troy ounce.

VISHAY FACES INTENSE COMPETITION IN ITS BUSINESS.

     Vishay's business is highly competitive worldwide, with low transportation
costs and few import barriers. Vishay competes principally on the basis of
product quality and reliability, availability, customer service, technological
innovation, timely delivery and price. The electronics components industry has
become increasingly concentrated and globalized in recent years and Vishay's
major competitors, some of which are larger than Vishay, have significant
financial resources and technological capabilities.

VISHAY'S BACKLOG IS SUBJECT TO CUSTOMER CANCELLATION.

     Many of the orders that comprise Vishay's backlog may be canceled by
customers without penalty. Customers may on occasion double and triple order
components from multiple sources to ensure timely

                                        13
   19

delivery when backlog is particularly long. Customers often cancel orders when
business is weak and inventories are excessive, a phenomenon that Vishay has
experienced in the current economic slowdown. Therefore, Vishay cannot be
certain the amount of its backlog does not exceed the level of orders that will
ultimately be delivered. Vishay's results of operations could be adversely
impacted if customers were to cancel a material portion of orders in Vishay's
backlog.

VISHAY MAY NOT HAVE ADEQUATE FACILITIES TO SATISFY FUTURE INCREASES IN DEMAND
FOR ITS PRODUCTS.

     Vishay's business is cyclical and in periods of a rising economy may
experience intense demand for its products. During such periods, Vishay may have
difficulty expanding its manufacturing to satisfy demand. Factors which could
limit such expansion include delays in procurement of manufacturing equipment,
shortages of skilled personnel and capacity constraints at Vishay's facilities.
If Vishay is unable to meet its customers' requirements and its competitors
sufficiently expand production, Vishay could lose customers and/or market share.
This could have an adverse effect on Vishay's financial condition, results of
operations and prospects.

FUTURE CHANGES IN VISHAY'S ENVIRONMENTAL LIABILITY AND COMPLIANCE OBLIGATIONS
MAY HARM VISHAY'S ABILITY TO OPERATE OR INCREASE COSTS.

     Vishay's manufacturing operations, products and/or product packaging are
subject to environmental laws and regulations governing air emissions,
wastewater discharges, the handling, disposal and remediation of hazardous
substances, wastes and certain chemicals used or generated in Vishay's
manufacturing processes, employee health and safety labelling or other
notifications with respect to the content or other aspects of Vishay's
processes, products or packaging, restrictions on the use of certain materials
in or on design aspects of Vishay's products or product packaging and
responsibility for disposal of products or product packaging. More stringent
environmental regulations may be enacted in the future, and Vishay cannot
presently determine the modifications, if any, in Vishay's operations that any
such future regulations might require, or the cost of compliance with these
regulations. In order to resolve liabilities at various sites, Vishay has
entered into various administrative orders and consent decrees, some of which
may, under certain conditions, be reopened or subject to renegotiation.

  RISKS RELATED TO VISHAY'S OPERATIONS OUTSIDE THE UNITED STATES

VISHAY DERIVES A SUBSTANTIAL AMOUNT OF ITS REVENUES FROM OUTSIDE THE UNITED
STATES.

     Approximately 56% of Vishay's revenues during 2000 were derived from sales
to customers outside the United States. Vishay's operating results could be
adversely affected by currency exchange rate fluctuations, regional inflation,
changes in monetary policy and tariffs, changes in local laws and regulations in
jurisdictions other than the U.S., international trade restrictions,
intergovernmental disputes, local laws that increase labor costs and reduction
or cancellation of government grants, tax benefits or other incentives.

VISHAY OBTAINS SUBSTANTIAL BENEFITS BY OPERATING IN ISRAEL, BUT THESE BENEFITS
MAY NOT CONTINUE.

     Vishay has increased its operations in Israel over the past several years.
The low tax rates in Israel applicable to earnings of Vishay's operations in
that country, compared to the rates in the U.S., have had the effect of
increasing Vishay's net earnings. In addition, Vishay has taken advantage of
certain incentive programs in Israel, which take the form of grants designed to
increase employment in Israel. Any significant increase in the Israeli tax rates
or reduction or elimination of the Israeli grant programs that have benefited
Vishay could have an adverse impact on Vishay's results of operations. See Note
1 to the Consolidated Financial Statements in Vishay's 2000 Annual Report on
Form 10-K incorporated by reference in this prospectus for a description of
Vishay's accounting policy for grants received by certain subsidiaries from
governments outside the United States.

VISHAY ATTEMPTS TO IMPROVE PROFITABILITY BY OPERATING IN COUNTRIES IN WHICH
LABOR COSTS ARE LOW, BUT THE SHIFT OF OPERATIONS TO THESE REGIONS MAY ENTAIL
CONSIDERABLE EXPENSE.

     Vishay's strategy is aimed at achieving significant production cost savings
through the transfer and expansion of manufacturing operations to and in
countries with lower production costs, such as Israel, Mexico, Portugal, the
Czech Republic, Taiwan and the People's Republic of China. In this process,
Vishay may experience under-utilization of certain plants and factories in high
labor cost regions and capacity constraints in plants and factories located in
low labor cost regions. This may result initially in production inefficiencies
and higher costs. Such costs include those associated with compensation in
connection with work force reductions and plant closings in the higher labor
cost regions, and start-up expenses, manufacturing and construction delays, and
increased depreciation costs in connection with the initiation or expansion of
production in lower labor cost regions. For example, during the first quarter of
2001 restructuring costs were $6.0 million as a result of Vishay's accelerated
effort to streamline operations in response to the continued weakness in the
electronic components market at the time, and we estimate that additional
restructuring costs during 2001 will be approximately $30 million.

     As Vishay implements transfers of certain of its operations it may
experience strikes or other types of labor unrest as a result of lay-offs or
termination of Vishay's employees in high labor cost countries.

  RISKS RELATED TO VISHAY'S CAPITAL STRUCTURE

THE HOLDERS OF CLASS B COMMON STOCK HAVE VOTING CONTROL OF VISHAY.


     Vishay has two classes of common stock: common stock and Class B common
stock. The holders of common stock are entitled to one vote for each share held,
while the holders of Class B common stock are entitled to 10 votes for each
share held. Currently, the holders of the Class B common stock hold 54.1% of the
voting power of Vishay. This includes 41.3% of the total voting power owned or
controlled by Dr. Felix Zandman, the Chairman of the Board and Chief Executive
Officer of Vishay. As a result, the holders of Class B common stock are able to
cause the election of the entire board of directors of Vishay. The holders of
the Class B common stock may also be able to approve other action as
stockholders without obtaining the votes of other stockholders of Vishay.


THE EXISTENCE OF THE CLASS B COMMON STOCK MAY DEPRIVE OTHER STOCKHOLDERS OF A
PREMIUM VALUE FOR THEIR SHARES IN A TAKEOVER.

     The effective control of Vishay by holders of the Class B common stock may
make Vishay less attractive as a target for a takeover proposal. It may also
render more difficult or discourage a merger proposal or proxy contest for the
removal of the incumbent directors, even if such actions were favored by all
stockholders of Vishay other than the holders of the Class B common stock.
Accordingly, this may deprive the holders of common stock of an opportunity they
might otherwise have to sell their shares at a premium over the prevailing
market price in connection with a merger or acquisition of Vishay with or by
another company.

                          FORWARD LOOKING INFORMATION

     Certain statements contained in or incorporated by reference into this
document are "forward looking statements." These forward looking statements
generally can be identified by use of statements that include phrases such as
"believe," "expect," "anticipate," "intend," "plan," "foresee," "likely," "will"
or other similar words or phrases. Similarly, statements that describe our
objectives, plans or goals are or may be forward looking statements. All forward
looking statements involve risks and uncertainties. In particular, any
statements regarding the benefits of the offer and the merger, as well as
expectations with respect to future business performance, operating efficiencies
and cost savings, are subject to known and unknown risks, uncertainties and
contingencies, many of which are beyond the control of Vishay and Siliconix,
which may cause actual results, performance or achievements to differ materially
from anticipated results, performance or achievements. Factors that might affect
such forward looking statements include, among other things:

     - the ability to fully integrate Siliconix into Vishay's operations,

     - overall economic and business conditions,

     - the demand for Vishay's and Siliconix's goods and services,

     - competitive factors in the industries in which Vishay and Siliconix
       compete,

     - changes in government regulation,

     - changes in tax requirements, including tax rate changes, new tax laws and
       revised tax law interpretations,

     - developments in and results of litigation, including the stockholder
       actions commenced after announcement of Vishay's initial proposal to
       acquire the publicly held shares of Siliconix,

     - interest rate fluctuations, foreign currency rate fluctuations and other
       capital market conditions,

     - economic and political conditions in international markets, including
       governmental changes and restrictions on the ability to transfer capital
       across borders,

     - the timing, impact and other uncertainties of pending and future
       acquisitions by Vishay; and

     - the ability to achieve anticipated synergies and other cost savings in
       connection with such future acquisitions.

     These factors and the risk factors described in the previous section are
not necessarily all of the important factors that could cause actual results,
performance or achievements to differ materially from those expressed in any of
our forward looking statements. Other unknown or unpredictable factors also
could have material adverse effects on our future results, performance or
achievements. The forward looking statements included in this document are made
only as of the date of this document, and we do not have any obligation to
publicly update any forward looking statements to reflect subsequent events or
circumstances. We cannot assure you that projected results or events will be
achieved or will occur.

                              RECENT DEVELOPMENTS

     On April 2, 2001, Vishay announced a proposal to acquire General
Semiconductor, Inc., which is listed on the New York Stock Exchange under the
symbol "SEM." Under the proposal, Vishay would exchange one share of Vishay
common stock for every two shares of General Semiconductor. Vishay made its
proposal to General Semiconductor through a letter which was sent by Vishay to
General Semiconductor's President and Chief Executive Officer, Ronald A.
Ostertag. General Semiconductor has rejected publicly the Vishay proposal.

     On April 25, 2001, Siliconix filed a patent infringement lawsuit against
General Semiconductor. The suit was filed in the United States District Court
for the Northern District of California and alleged that certain General
Semiconductor products infringe two patents held by Siliconix.


     On June 4, 2001, Vishay completed the private offering of a series of
zero-coupon convertible subordinated notes due 2021, known as Liquid Yield
Option(TM) Notes (LYONs), having a yield to maturity of 3.0%. The LYONs were
issued at an issue price of $551.26 per LYON (55.126% of the principal amount at
maturity). The gross proceeds from the offering were approximately $303.2
million ($353.5 million if an over-allotment option is exercised in full).
Vishay intends to use the proceeds of the offering to retire existing debt and
for general corporate purposes. The LYONs will be convertible into approximately
9.7 million shares of Vishay common stock (11.3 million shares if the
over-allotment option is fully exercised).

                            BACKGROUND OF THE OFFER

     The following discussion presents background information concerning the
offer and the short-form merger. Certain information on the actions of
Siliconix's management, the special committee of the Siliconix board of
directors and the Siliconix board of directors, and the advisors to Siliconix
and its board and the special committee has been obtained from Siliconix.

EVENTS LEADING TO THE OFFER

     Vishay, through Vishay TEMIC, owns approximately 80.4% of the outstanding
shares of Siliconix common stock. Vishay acquired its interest in Siliconix from
a division of the microelectronics consortium of Daimler-Benz AG, a German
corporation, on March 2, 1998. In the transaction, Vishay acquired 8,010,000 of
Siliconix's shares (pre-split) and TEMIC Semiconductor GmbH, a producer of
discrete active electronic components, for a combined purchase price of
$549,889,000 in cash. The acquisition agreement allocated approximately
$234,667,000 of the combined purchase price to the acquisition of the Siliconix
stock.

     Upon consummation of the sale by Daimler-Benz to Vishay of the controlling
interest in Siliconix, the three representatives of Daimler-Benz on Siliconix's
board of directors resigned and three designees of Vishay, each of whom was a
Vishay employee, were appointed to the board in their place.

     On February 16, 2000, the stockholders of Siliconix approved a
three-for-one split of Siliconix common stock which was effected on February 29,
2000, as a result of which the number of shares held by Vishay TEMIC was
increased to 24,030,000, although its percentage interest remained unchanged.

     Since Vishay TEMIC's acquisition of its interest in Siliconix, Siliconix's
products have been marketed by Vishay's worldwide sales organization under the
Siliconix brand name, and Siliconix's results of operations and other financial
information have been consolidated in Vishay's financial statements.

     On June 16, 2000, Siliconix's chief financial officer resigned, and William
Clancy, Vishay's controller, became the acting chief accounting officer of
Siliconix.

     Vishay has from time to time considered increasing the size of its interest
in Siliconix in a manner that would allow all other stockholders an equal
opportunity to dispose of their shares. On occasion, representatives of Vishay
have informally mentioned the possibility of such an offer to members of the
board of Siliconix. With the recent slowing of growth in the technology sector
and the accompanying pressure on the stock price of Siliconix, Vishay felt that
stockholders might react favorably to an acquisition proposal by Vishay in which
Vishay would acquire their shares at a premium to current market prices.
Accordingly, at its meeting on February 19, 2001, Vishay's board of directors
authorized its management to contact Siliconix's board of directors to discuss a
possible tender offer for any and all shares not already owned by Vishay.


     On February 22, 2001, Vishay sent a letter to Siliconix's board of
directors proposing to purchase the shares through a tender offer at a price of
$28.82 per share in cash. Vishay did not retain any financial advisor to perform
a valuation of Siliconix in connection with its proposal or otherwise with
respect to the offer. Simultaneously with the letter, Vishay issued a press
release disclosing the offer and its material terms to the public. The following
is the text of Vishay's letter to the Siliconix board:


                                        25

February 22, 2001

Mr. Glyndwr Smith
Chairman of the Board of Directors
Siliconix incorporated
2201 Laurelwood Road
Santa Clara, California 95054
Attention: Board of Directors

Gentlemen:

     We are proposing to purchase any and all outstanding shares of common stock
of Siliconix incorporated not already owned by Vishay Intertechnology, Inc. at a
price of $28.82 per share in cash. The purchase would be made through a tender
offer, subject to customary conditions, in accordance with the rules of the
Securities and Exchange Commission.

     Alternatively, we could offer to exchange the Siliconix shares for shares
of common stock of Vishay. Depending upon whether such exchange would be
tax-free to the Siliconix stockholders, we would expect that the value per share
of Siliconix in the exchange would be somewhat less than the cash price.

     If we hold at least 90 percent of the outstanding Siliconix shares
following completion of our offer, we may effect a "short-form" merger of
Siliconix with a Vishay subsidiary under Delaware law. If such a merger takes
place promptly after the offer, the consideration given to stockholders in the
merger would be the same as the consideration received by tendering stockholders
in the offer.

     We are not requesting that you enter into any agreement with respect to the
offer or pay any sort of break-up or similar fee in the event that the offer is
not consummated, including because of a higher offer from a subsequent bidder.
Our offer would not foreclose any other person from making a higher offer for
the shares that we do not already own.

     We recognize that a majority of the board of directors of Siliconix is
either affiliated with Vishay or serves with Siliconix management. We request
the opportunity to discuss our offer with a special committee of independent,
non-management Siliconix directors who are unaffiliated with Vishay. We only
expect to proceed with our offer if the special committee, after consultations
with its financial and legal advisors, concludes that the offer is fair to
Siliconix stockholders. In addition, we could also determine not to proceed with
the offer if in our sole judgment changes in economic, business or market
conditions make the offer unadvisable.

     Please call me at (610) 644-1300 at your earliest convenience to discuss
this matter. We look forward to hearing from you.

Sincerely,

Avi D. Eden
Vice Chairman

     On February 26, 2001, Siliconix's board of directors met by conference call
to consider Vishay's proposal and to designate a special committee responsible
for evaluating and negotiating the proposal. At that meeting, the board
increased the authorized number of directors of Siliconix from six to eight and
appointed Timothy V. Talbert to fill one of two newly-created vacancies on the
board. The board of directors also established the special committee and named
Mr. Talbert and another Siliconix director, Mark B. Segall, as the committee's
two members. Neither Mr. Talbert nor Mr. Segall has any current interest in or
affiliation with Siliconix or Vishay, other than as directors of Siliconix and
the ownership for over ten years of 2,014 shares of Vishay stock by Mr. Talbert
and his wife in individual retirement accounts. However, both Messrs. Talbert
and Segall have had material relationships with Vishay in the

                                        26
   32

past. The Siliconix board did not name any other members of the full board to
the special committee because, of its five other members, three (Lori Lipcaman,
Everett Arndt and Glyndwr Smith) are management employees of Vishay, one
(Michael Rosenberg) is a consultant to Vishay, and the fifth (King Owyang) is
the president and chief executive officer of Siliconix and holds options to
purchase 102,500 shares of Vishay common stock. See "Interests of Certain
Persons" on page 48.

     The Siliconix board of directors authorized and directed the special
committee to assess Vishay's February 22, 2001 proposal. The full board also
authorized the special committee to consider possible alternatives to the Vishay
proposal. The board further authorized the special committee to communicate and,
as the committee considered appropriate, negotiate directly with Vishay
concerning the terms and conditions of Vishay's proposal. The special committee
was also authorized to hire an investment banking firm and a law firm to provide
the committee with financial and legal advice in performing these tasks.

     On February 27, 2001, Siliconix sent a letter to Vishay acknowledging its
receipt of the offer and informing Vishay of the formation of the special
committee, which Siliconix announced to the public through the issuance of a
press release on March 1, 2000. The following is the text of Siliconix's letter
to Vishay:

February 27, 2001

Avi Eden, Esq.
Vice Chairman
Vishay Intertechnology, Inc.
63 Lincoln Highway
Malvern, PA 19355

Dear Mr. Eden:

The Siliconix Board of Directors has received your letter of February 22, 2001,
in which you disclosed a proposal by Vishay Intertechnology, Inc. to purchase
all of the shares of Siliconix incorporated that it does not already own for
$28.82 in cash or, alternatively, for an undetermined number of shares of Vishay
stock for each share of Siliconix stock.

The Siliconix Board has appointed a special committee of independent,
non-management Siliconix directors who are unaffiliated with Vishay. This
committee will evaluate your offer thoroughly and objectively and will advise
the Siliconix Board accordingly. We will communicate our position to you
thereafter.

Sincerely,

Glyndwr Smith
Chairman, Siliconix incorporated

     The Siliconix special committee subsequently engaged the investment banking
firm of Lehman Brothers Inc. as its financial advisor and the law firm of Heller
Ehrman White & McAuliffe LLP as its legal counsel.

     Over the next several weeks the special committee met on various occasions
with its financial and legal advisors to discuss the Vishay proposal, the
business and prospects of Siliconix and trends in the electronic components
industry generally. Lehman Brothers conducted various financial diligence
investigations of Siliconix during this period and Heller Ehrman conducted
various legal investigations.

     On April 5, 2001, the members of the special committee, together with their
financial and legal advisors, met in New York City with representatives of
Vishay and its legal advisor. The parties discussed the cash price that had been
proposed by Vishay as well as structuring issues and other non-price terms of

                                        27
   33

the Vishay offer. The special committee and its financial advisor expressed the
view that, despite the slow economy, the state of the semiconductor industry and
the depressed stock market, they believed that $28.82 was not a fair price for
the Siliconix shares. The parties agreed to resume their discussion after Lehman
Brothers had completed its valuation work on Siliconix and the special committee
had had an opportunity to review that work.

     Lehman Brothers continued its work during the following weeks and
communicated with the special committee to convey the results of its valuation
analysis.

     On May 2, 2001, the members of the special committee, together with their
financial and legal advisors, again met in New York City with representatives of
Vishay and its legal advisor. The special committee and its financial advisor
reiterated their view that the $28.82 per share price that had been proposed by
Vishay was inadequate. Vishay's representatives indicated that Vishay was
prepared to offer a higher price but only in a transaction in which the
consideration consisted primarily or exclusively of Vishay common stock. The
parties then discussed this proposal, including a possible exchange ratio,
possible adjustments to the exchange ratio depending on the price levels of
Vishay stock, structuring issues and other non-cash terms of the offer. Although
no agreement was reached on these issues, Lehman Brothers was directed to
commence a diligence analysis of Vishay in order to form a view as to the value
of Vishay stock as consideration in the offer.


     In deciding to change its proposal from a cash offer to a stock offer,
Vishay representatives reasoned that certain members of Vishay's senior
management had questioned the value to Vishay of purchasing the 19.6% of
Siliconix that Vishay did not already own; that at $28.82 per share Vishay would
be paying almost as much for 19.6% of Siliconix as it had paid for 80.4% of
Siliconix three years earlier; that management was therefore unwilling to
recommend to the Vishay board a cash transaction at a price per share in excess
of $28.82; but that management was prepared to recommend a share exchange at a
ratio which would provide greater value per share of Siliconix stock but would
not increase the cost of the transaction to Vishay based upon the price of
Vishay's stock at the time Vishay first proposed to acquire all of Siliconix
stock that it did not already own.



     Following the May 2 meeting, counsel for Vishay and the special committee
exchanged drafts of and comments upon a form of merger agreement between Vishay
and Siliconix providing for a stock-for-stock transaction.



     Based upon the prices of Vishay stock during the period prior to the
announcement of the offer, the $28.82 cash offer was the equivalent of
approximately 9 million shares of Vishay common stock, or 1.5 shares of Vishay
common stock for each share of publicly traded Siliconix common stock. The
1.5 ratio multiplied by the prices for Vishay common stock in the range of
approximately $24 to $28 during the week before the announcement of the offer on
May 25, 2001 would have yielded a premium to the cash offer price, which Vishay
believed would provide a basis for further consideration by the special
committee.


     Thereafter, as a result of movements in the stock market and Vishay's
perception of a continuing deterioration in the electronic components market
generally and in the space in which Siliconix operates in particular, Vishay
formed a view that it was prepared to offer to acquire the publicly held stock
of Siliconix in a stock-for-stock exchange offer without a merger agreement and
without the advance approval of the special committee or favorable
recommendation of the Siliconix board.


     On May 23, 2001, Vishay informed the special committee that it was
considering making an exchange offer for Siliconix stock at the ratio of 1.5
shares of Vishay common stock for each share of Siliconix common stock without
first obtaining the special committee's approval. On May 24, 2001, the board of
directors of Vishay met and determined to proceed with the offer.


     On May 25, 2001, Vishay placed an advertisement in the Wall Street Journal
and issued a press release announcing the commencement of the offer.

                                        28
   34

EVENTS OCCURRING AFTER THE COMMENCEMENT OF THE OFFER

     On May 25, 2001, Vishay made a written request pursuant to Rule 14d-5(a) of
the Exchange Act for Siliconix's stockholder list and security position
listings.

     On May 30, 2001, Vishay announced the private offering of a series of
zero-coupon convertible subordinated notes due 2021, known as LYONs. See "Recent
Developments" on page 20. Following the announcement of the offer and of the
LYONs offering, the Vishay stock price experienced a marked decline, from an
NYSE closing price of $25.81 on the day prior to the commencement of the offer
to a closing price of $20.60 on May 31, 2001.

     Following commencement of the offer, representatives of Vishay and of the
Siliconix's special committee held informal discussions concerning the offer.
During those discussions, the representatives of the special committee noted the
decline in Vishay's stock price. Those representatives expressed the view that
the special committee would not be likely to recommend the offer at the then
current price levels of Vishay stock, which at such levels provided value of
less than $34 per Siliconix share.


     On June 8, 2001, Siliconix disseminated and filed with the SEC a
solicitation/recommendation statement, in which it disclosed that the Siliconix
board and the special committee were taking no position with respect to the
offer and the merger.


CERTAIN LITIGATION


     In February and March 2001, several purported class action complaints were
filed in the Court of Chancery in and for New Castle County, Delaware and the
Superior Court of the State of California against Vishay, Siliconix and the
directors of Siliconix in connection with Vishay's announced proposal to
purchase all issued and outstanding shares of Siliconix common stock not already
owned by Vishay. The California class actions also name as defendants the
directors of Vishay. The class actions, filed on behalf of all Siliconix
stockholders other than Vishay, allege, among other things, that Vishay's $28.82
per share cash proposal was unfair and a breach of fiduciary duty. The actions
seek injunctive relief, damages and other relief.


     One of the Delaware class actions brought on behalf of all minority
stockholders of Siliconix was filed on March 8, 2001, by Raymond L. Fitzgerald,
allegedly a beneficial owner of over 137,000 shares of Siliconix common stock.
This action claims that Vishay, Siliconix and six of the seven Siliconix
directors breached their fiduciary duties to deal fairly with, and to pay a fair
price to, the minority stockholders of Siliconix. This suit also contains
derivative claims against Vishay on behalf of Siliconix alleging self-dealing
and waste because Vishay purportedly usurped Siliconix's intellectual property
and inventions, appropriated Siliconix's separate corporate identity and
obtained a below-market loan from Siliconix.

     Mr. Fitzgerald makes claims relating to, among other things, (i) the
alleged unfair price and timing of the transaction proposed in Vishay's February
22, 2001 letter to the Siliconix board, (ii) the alleged unfair process employed
by Vishay in pursuing the proposed transaction, including, in particular, the
formation of, according to Mr. Fitzgerald, a sham and unempowered special
committee by the Siliconix board of directors in an effort to mislead minority
stockholders of Siliconix, (iii) alleged conflicts of interest of the special
committee, (iv) alleged materially misleading statements or omissions made by
Vishay and Siliconix with respect to the proposed transaction, and (v) Vishay's
purported pattern over the years of enriching itself at the expense of Siliconix
and its minority stockholders.

     Mr. Fitzgerald has alleged that the special committee is not independent
because, among other things, one of its two members, Mr. Mark Segall, should not
be considered "unaffiliated" with Vishay. The complaint notes that until 1999,
Mr. Segall was a partner with the law firm of Kramer Levin Naftalis & Frankel
LLP during which time he represented Vishay as its corporate counsel and
participated in the transaction in which Vishay first acquired its interest in
Siliconix, and that Mr. Segall is listed as Vishay's representative, attorney or
required recipient of any notice on certain of Vishay's SEC filings and
corporate documents. The complaint also alleges that Mr. Segall acted as a
representative of Vishay after his

                                        29
   35

departure from Kramer Levin. Mr. Fitzgerald has alleged that the special
committee has been given no real bargaining power in the proposed transaction.

     On May 2, 2001, Mr. Fitzgerald filed a request for admissions requesting
certain admissions or denials relating to relationships between Mr. Timothy V.
Talbert, Mr. Segall and Vishay. On May 11, 2001, Mr. Fitzgerald filed a motion
to consolidate, and requested that he be named the lead plaintiff in the
lawsuits in Delaware that have been filed in connection with the proposed
transaction. On May 22, 2001, the Court of Chancery consolidated the Delaware
actions under the caption "In re Siliconix Incorporated Shareholders
Litigation." Mr. Fitzgerald's motion to be named lead plaintiff was initially
opposed by other plaintiffs in the Delaware actions, and on May 24, 2001,
plaintiff Griffin Portfolio Management Corp. also moved to be appointed as lead
plaintiff. On May 30, 2001, plaintiffs Fitzgerald and Griffin Portfolio
Management Corp. informed the court that they had agreed that Mr. Fitzgerald
would be the sole lead plaintiff and counsel for Mr. Fitzgerald and Griffin
Portfolio Management Corp. would be co-lead counsel for plaintiff and the
proposed class.


     On or about May 31, 2001, plaintiff Fitzgerald served an amended complaint,
an application for a preliminary injunction against proceeding with or taking
steps to give effect to the offer or the contemplated short-form merger, a
motion to expedite proceedings and additional discovery requests. The amended
complaint names as additional defendants Vishay TEMIC Semiconductor Acquisition
Holdings Corp., Mr. Talbert and Dr. Zandman. In addition to his prior
allegations, plaintiff claims, among other things, that in connection with the
proposed offer and short-form merger, defendants have allegedly violated (i)
their duty to deal fairly from a timing and process perspective with the
minority stockholders of Siliconix, (ii) their duties of loyalty and candor, and
(iii) Vishay's obligation to pay a fair price to the Siliconix minority
stockholders. Plaintiff alleges, among other things, that Vishay has unfairly
timed the proposed transaction to take advantage of the purported temporarily
and artificially depressed market price for Siliconix stock. Plaintiff also
contends that defendants breached fiduciary duties of candor and full disclosure
by purportedly misleading the minority stockholders in connection with the
alleged sham nature of the special committee, the timing of the proposed
transactions, the prospects for and value of Siliconix and the prospects for and
value of Vishay. Plaintiff further alleges that defendants have breached their
purported fiduciary duty to pay a fair price in connection with the offer and
short-form merger in that the proposed consideration is allegedly below the
going concern value of Siliconix and what could be obtained in an arms' length,
third party transaction.



     Following expedited discovery and briefing, on June 15, 2001, the court
heard argument on Mr. Fitzgerald's motion for a preliminary injunction to enjoin
the offer. On June 19, 2001, the court issued an order denying the motion.



     Vishay has moved to dismiss the amended complaint in the Delaware action.
On April 9, 2001, Vishay and those defendants that had been served moved for a
stay of the California actions. That motion is presently returnable on June 29,
2001.



     Copies of various complaints filed in connection with the transaction
proposed in Vishay's February 22, 2001 letter to the Siliconix board, including
the ones filed by Mr. Fitzgerald and Griffin Portfolio Management Corp., as well
as Mr. Fitzgerald's amended complaint filed after the commencement of the offer,
are attached as exhibits to the registration statement. Also attached as an
exhibit is the Court of Chancery's June 19, 2001 opinion. See also "Interests of
Certain Persons" on page 48.

                POSITION OF THE BOARD OF DIRECTORS OF SILICONIX



     As set forth in Siliconix's a solicitation/recommendation statement
disseminated and filed with the SEC on June 8, 2001, the Siliconix board and the
special committee of the Siliconix board are taking no position with respect to
the offer and the merger.



     Information about the recommendation of the Siliconix board of directors
and the special committee is more fully set forth in Siliconix's
Solicitation/Recommendation Statement on Schedule 14D-9, which was mailed to
Siliconix stockholders on or about June 8, 2001.


                        REASONS OF VISHAY FOR THE OFFER

     At meetings of Vishay's board of directors held on February 19, 2001 and on
May 24, 2001, Vishay's directors determined that the acquisition of the
Siliconix shares that Vishay does not own was in keeping with its corporate
strategy of complementing its internal growth with acquisitions that are likely
to benefit from cost reductions and synergies when combined with Vishay's
existing operations.

     In reaching its decision to make the offer, Vishay's board of directors
considered the following material factors, among others:

     - the expectation that Siliconix's business could be further integrated
       with the business of Vishay, which would enhance prospects for both
       companies;

     - the belief of Vishay's management that there are opportunities for
       reduction of Siliconix corporate costs, possible elimination of
       facilities of the combined company and potential cost reductions for
       purchased materials and services;


     - the belief of Vishay's management that by acquiring all of Siliconix,
      Vishay could achieve synergies by consolidating the management of
      Siliconix's plants with those of Vishay and by unifying and optimizing
      cash management;


     - the recent softening of the market for electronic components, as
       evidenced by first quarter results across the industry, and the
       particular need in this environment to focus on cost-cutting, operational
       efficiencies and product synergies;

     - the prospects that the current downturn in the electronic component
       industry would extend into the third quarter of 2001, and possibly
       beyond, and that, as the 80.4% owner of Siliconix, Vishay stands to be
       most affected by a falling off in the operating results of Siliconix;

     - stockholder allegations made from time to time, which Vishay believes are
       unfounded but which nonetheless have diverted management attention, that
       Vishay has used its position as controlling stockholder of Siliconix to
       usurp rights and opportunities of Siliconix to the detriment of
       Siliconix's minority stockholders; and

     - Vishay's history of long-term growth through acquisitions, including its
       substantial experience integrating acquired businesses with existing
       operations and thereby achieving synergies and cost savings.

             OTHER FACTORS TO CONSIDER BEFORE TENDERING YOUR SHARES

     In determining whether or not to tender your Siliconix shares in the offer,
you should consider the following factors, in addition to the risk factors and
other factors identified in this document. See "Risk Factors" beginning on page
11:

Vishay Business Considerations

     - Combining the business and operations of Vishay and Siliconix should
       result in operational efficiencies and cost savings that Vishay believes
       could not be achieved by Siliconix on a stand-alone basis. Vishay
       believes that these efficiencies and savings could be realized in
       administrative, human resources, information technology, purchasing,
       research and development, strategic planning and other corporate
       functions without impairing Siliconix's core operations.

     - Vishay should have broader access to capital markets and greater
       borrowing capacity than Siliconix, which could be used to finance
       acquisitions and capital expansion at Siliconix that may be foreclosed to
       Siliconix as an independent public company that is majority-owned by
       Vishay.

     - Because of the greater breadth of Vishay's operations and product lines,
       Vishay should experience less volatility in revenues and earnings than
       Siliconix, which has a much narrower product and operational base.

Vishay Stock and Market Considerations

     - Stockholders of Vishay have an ownership interest in a larger and more
       diversified company than Siliconix.

     - Vishay is actively covered by a number of members of the analyst
       community. Siliconix has no independent analyst coverage.

     - The market for Siliconix stock is relatively illiquid compared to the
       market in Vishay stock, with the average daily trading volume for Vishay
       stock being over twenty times as great as the average daily volume for
       Siliconix stock.

     - Because Vishay owns approximately 80.4% of the outstanding Siliconix
       stock, a sale of Siliconix in which stockholders would realize an
       acquisition premium is unlikely and cannot occur without the consent of
       Vishay.

Siliconix Business Considerations

     - Siliconix has already acted to cut costs and reduce operating expenses in
       order to maintain profitability in the current adverse economic
       environment.

     - Siliconix owns a valuable and extensive portfolio of intellectual
       property, and has a long tradition of innovative product development.
       Siliconix introduced 119 new products in 2000 alone.

     - Siliconix had its best year ever in 2000, with record earnings of $107.6
       million.

Siliconix Stock and Market Considerations

     - Siliconix has traded as high as $88.06 in the last 52 weeks, and has
       already recovered from its 52 week low of $16.94.

     - Siliconix stock price and operating performance can be expected to
       rebound further with improvements in the United States and world economy
       and when the inventory corrections in Siliconix's major markets have run
       their course.

     - Historically, Siliconix has recovered from adverse economic conditions
       ahead of corresponding improvements in Vishay's business generally.

                                        32
   38

     - As a Vishay stockholder, your interest in the performance and prospects
       of Siliconix will be indirect and in proportion to your relative holdings
       of Vishay stock. Accordingly, you may not realize the same financial
       benefit of future appreciation in the enterprise value of Siliconix that
       you would if you remained a Siliconix stockholder.

     - Siliconix stock has often traded historically at higher price to earnings
       multiples than the stock of Vishay.

     - Because Vishay owns approximately 80.4% of the outstanding Siliconix
       stock, there can be no effective "market check" on the Vishay offer. It
       is highly unlikely that any third party would bid for Siliconix in these
       circumstances.

Certain Allegations Against Vishay

     - It is alleged in the current litigation described in "Certain Litigation"
       beginning on page 29, that Vishay has usurped for itself patented
       technology actually developed by employees of Siliconix.

     - It has further been alleged that Vishay has caused Siliconix to lend
       funds to Vishay at rates that are below the rates that Siliconix could
       obtain from third party borrowers under similar circumstances.

     - It has further been alleged that Vishay has usurped for itself the
       corporate identity of Siliconix by causing the name Vishay to appear
       prominently at Siliconix's headquarters, on the business cards of
       Siliconix employees and in other contexts in which Siliconix is
       mentioned.

     - In the past, there have been claims that Vishay obtains products for
       resale from Siliconix at below market transfer prices.

     - There have also been claims that by awarding Vishay stock options to
       Siliconix employees and management, Vishay incentivizes these Siliconix
       personnel to act in the interests of Vishay rather than Siliconix.

     Vishay denies these claims and allegations.

                              FINANCIAL FORECASTS

     As part of its business planning cycles, the management of each of
Siliconix and Vishay from time to time have prepared internal financial
forecasts regarding its anticipated future operations. In the course of the
discussions described in "Background of the Offer," Vishay and Siliconix
provided these internal forecasts to each other and to Siliconix's special
committee's financial advisor.

     The internal financial forecasts regarding Siliconix prepared by
Siliconix's management reflected the following forecasted information (in
thousands, except per share amounts):

     The internal financial forecasts regarding Vishay prepared by Vishay's
management reflected the following forecasted information, exclusive of
restructuring charges (in thousands, except per share amounts):



                 CALENDAR YEAR                     SALES       EBITDA    NET INCOME    EPS

     The above forecasts of Siliconix and Vishay were prepared for internal
budgeting and planning purposes only and not with a view to public disclosure or
compliance with published guidelines of the SEC or the guidelines established by
the American Institute of Certified Public Accountants regarding projections or
forecasts. While presented with numerical specificity, the forecasts are based
upon a variety of assumptions relating to the business of Siliconix and Vishay
and are inherently subject to significant uncertainties and contingencies that
are beyond the control of the management of Siliconix and Vishay. These include
the impact of general economic and business conditions, the competitive
environment in which each operates and other factors. See "Forward Looking
Information" on page 16. Accordingly, actual results may differ materially from
those forecasted.

     The inclusion of the forecasts herein should not be regarded as a
representation by Siliconix or Vishay or any other person that such forecasts
are or will prove to be correct. By including the projections of Siliconix in
this document, Vishay does not adopt those projections. As a matter of course,
neither Siliconix nor Vishay makes public projections or forecasts of its
anticipated financial position or results of operations. Except to the extent
required under applicable securities laws, neither Siliconix nor Vishay intends
to make publicly available any update or other revisions to any of the forecasts
to reflect circumstances existing after the date of preparation of such
forecasts.

                                   THE OFFER

     We are offering to exchange 1.5 shares of Vishay common stock for each
outstanding share of Siliconix common stock which is validly tendered and not
properly withdrawn on or prior to the expiration date of the offer, subject to
the terms and conditions described in this prospectus and the related letter of
transmittal.

     The term "expiration date" means 12:00 midnight, New York City time, on
Friday, June 22, 2001, unless we extend the period of time for which the offer
is open, in which case the term "expiration date" means the latest time and date
on which the offer, as so extended, expires.

     You will not receive any fractional shares of Vishay common stock in the
offer or the merger. In lieu of any fractional share, you will receive cash
equal to the product of such fractional share, after combining all fractional
shares to which you would otherwise be entitled, and the closing price of Vishay
common stock as reported on the NYSE on the expiration date of the offer.

     If you are the record owner of your shares and you tender your shares
directly to the exchange agent, you will not be obligated to pay any charges or
expenses of the exchange agent or any brokerage commissions. If you own your
shares through a broker or other nominee, and your broker tenders the shares on
your behalf, your broker may charge you a fee for doing so. You should consult
your broker or nominee to determine whether any charges will apply.

     Our obligation to exchange Vishay shares for Siliconix shares in the offer
is subject to several conditions referred to below under "Conditions of the
Offer."

TIMING OF THE OFFER

     Our offer is scheduled to expire at 12:00 midnight, New York City time, on
Friday, June 22, 2001. For more information, see the discussion under
"Extension, Termination and Amendment" below.

EXTENSION, TERMINATION AND AMENDMENT

     We expressly reserve the right, in our sole discretion, at any time or from
time to time to extend the period of time during which our offer remains open,
and we can do so by giving oral or written notice of such extension to the
exchange agent. If we decide to extend our offer, we will make an announcement
to that effect no later than 9:00 a.m., New York City time, on the next business
day after the previously scheduled expiration date. We are not making any
assurance that we will exercise our right to extend our offer, although we
currently intend to do so until all conditions have been satisfied or, where
permissible, waived. During any such extension, all Siliconix shares previously
tendered and not withdrawn will remain subject to the offer, subject to your
right to withdraw your Siliconix shares prior to the expiration date.

     Subject to the SEC's applicable rules and regulations, we also reserve the
right, in our sole discretion, at any time or from time to time, to delay our
acceptance for exchange or our exchange of any Siliconix shares pursuant to our
offer, regardless of whether we previously accepted Siliconix shares for
exchange, or to terminate our offer and not accept for exchange or exchange any
Siliconix shares not previously accepted for exchange or exchanged, upon the
failure of any of the conditions of the offer to be satisfied or, where
permissible, waived, or otherwise to amend the offer in any respect (except as
described below), by giving oral or written notice of such delay, termination or
amendment to the exchange agent and by making a public announcement. We will
follow any extension, delay, termination or amendment, as promptly as
practicable, with a public announcement. In the case of an extension, any such
announcement 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. Subject to
applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act,
which require that any material change in the information published, sent or
given to the stockholders in connection with the offer be promptly sent to
stockholders in a manner reasonably designed to inform stockholders of such
change) and without limiting the manner in which we may choose to make any
public announcement, we assume no obligation to publish, advertise or otherwise
communicate any such public announcement other than by making a release to the
Dow Jones News Service.
                                        35
   41

     We expressly reserve the right, at any time and from time to time, to
modify the terms and conditions of the offer, except that the minimum condition,
the registration statement effectiveness condition and the listing condition may
not be modified or waived.

     If we make a material change in the terms of the offer or the information
concerning the offer, or if we waive a material condition of the offer, we will
extend the offer to the extent required under the Exchange Act. If, prior to the
expiration date, we change the consideration offered to you, that change will
apply to all holders whose Siliconix shares are accepted for exchange pursuant
to the offer. If at the time notice of that change is first published, sent or
given to you, the offer is scheduled to expire at any time earlier than the
tenth business day from and including the date that the notice is first so
published, sent or given, we will extend the offer until the expiration of that
ten business-day period. For purposes of the offer, a "business day" means any
day other than a Saturday, Sunday or federal holiday and consists of the time
period from 12:01 a.m. through 12:00 midnight, New York City time.

EXCHANGE OF SILICONIX SHARES; DELIVERY OF VISHAY COMMON STOCK

     Upon the terms and subject to the conditions of the offer (including, if
the offer is extended or amended, the terms and conditions of the extension or
amendment), we will accept for exchange Siliconix shares validly tendered and
not properly withdrawn as promptly as permitted to do so under applicable law
and will exchange Vishay common stock for the shares of Siliconix common stock
promptly thereafter. In all cases, exchange of Siliconix shares tendered and
accepted for exchange pursuant to the offer will be made only after timely
receipt by the exchange agent of certificates for those Siliconix shares (or a
timely confirmation of a book-entry transfer of those Siliconix shares in the
exchange agent's account at The Depository Trust Company), a properly completed
and duly executed letter of transmittal (or a manually signed facsimile of that
document), and any other required documents, or you must comply with the
guaranteed delivery procedures set forth in "Guaranteed Delivery" beginning on
page 38.

     For purposes of the offer, we will be deemed to have accepted for exchange
Siliconix shares validly tendered and not properly withdrawn when, as and if we
notify the exchange agent of our acceptance of the tenders of those Siliconix
shares pursuant to the offer. The exchange agent will deliver shares of Vishay
common stock in exchange for Siliconix shares pursuant to the offer and cash
instead of a fraction of a share of Vishay common stock (as specified in this
document) as soon as practicable after receipt of our notice. The exchange agent
will act as agent for tendering stockholders for the purpose of receiving Vishay
common stock and cash to be paid instead of a fraction of a share of Vishay
common stock and transmitting such stock and cash to you. You will not receive
any interest on any cash that we pay you, even if there is a delay in making the
exchange.

     If we do not accept any tendered Siliconix shares for exchange pursuant to
the terms and conditions of the offer for any reason, or if certificates are
submitted for more Siliconix shares than are tendered, we will return
certificates for such unexchanged Siliconix shares without expense to the
tendering stockholder. In the case of Siliconix shares tendered by book-entry
transfer of such Siliconix shares into the exchange agent's account at DTC
pursuant to the procedures set forth below under the discussion entitled
"Procedure for Tendering Shares," those Siliconix shares will be credited to an
account maintained within DTC, as soon as practicable following expiration or
termination of the offer.

     If we increase the consideration offered to Siliconix stockholders in the
offer prior to the expiration date, such increased consideration will be given
to all stockholders whose Siliconix shares are tendered pursuant to the offer,
whether or not such Siliconix shares were tendered or accepted for exchange
prior to such increase in consideration.

CASH INSTEAD OF FRACTIONAL SHARES OF VISHAY COMMON STOCK

     We will not issue certificates representing a fraction of a share of Vishay
common stock pursuant to the offer or the merger. Instead, each tendering
stockholder who would otherwise be entitled to a fraction of a share of Vishay
common stock, after combining all fractional shares to which such stockholder
would otherwise be entitled, will receive cash in an amount equal to the product
obtained by multiplying (i) the
                                        36
   42

fraction of a share of Vishay common stock to which the holder would otherwise
be entitled by (ii) the closing price of Vishay common stock as reported on the
NYSE on the expiration date of the offer.

PROCEDURE FOR TENDERING SHARES

     For you to validly tender Siliconix shares pursuant to our offer, (a) a
properly completed and duly executed letter of transmittal (or manually executed
facsimile of that document), along with any required signature guarantees, or an
agent's message in connection with a book-entry transfer, and any other required
documents, must be transmitted to and received by the exchange agent at one of
its addresses set forth on the back cover of this prospectus, and certificates
for tendered Siliconix shares must be received by the exchange agent at such
address or those Siliconix shares must be tendered pursuant to the procedures
for book-entry tender set forth below (and a book-entry confirmation of receipt
of such tender received), in each case before the expiration date, or (b) you
must comply with the guaranteed delivery procedures set forth below.

     The term "agent's message" means a message, transmitted by DTC to, and
received by, the exchange agent and forming a part of a book-entry confirmation,
which states that DTC has received an express acknowledgment from the
participant in DTC tendering the Siliconix shares which are the subject of the
book-entry confirmation, that the participant has received and agrees to be
bound by the terms of the letter of transmittal and that we may enforce that
agreement against the participant.

     The exchange agent will establish an account with respect to the Siliconix
shares at DTC for purposes of the offer within two business days after the date
of this prospectus, and any financial institution that is a participant in DTC
may make book-entry delivery of the Siliconix shares by causing DTC to transfer
such Siliconix shares into the exchange agent's account in accordance with DTC's
procedure for the transfer. However, although delivery of Siliconix shares may
be effected through book-entry at DTC, the letter of transmittal (or a manually
signed facsimile thereof), with any required signature guarantees, or an agent's
message in connection with a book-entry transfer, and any other required
documents, must, in any case, be transmitted to and received by the exchange
agent at one of its addresses set forth on the back cover of this prospectus
prior to the expiration date of the offer, or the guaranteed delivery procedures
described below must be followed.

     Signatures on all letters of transmittal must be guaranteed by an eligible
institution, except in cases in which Siliconix shares are tendered either by a
registered holder of Siliconix shares who has not completed the box entitled
"Special Issuance Instructions" or the box entitled "Special Delivery
Instructions" on the letter of transmittal or for the account of an eligible
institution. By "eligible institution," we mean a bank, broker, dealer, credit
union, savings association or other entity which is a member in good standing of
a recognized Medallion Program approved by the Securities Transfer Association
Inc., including the Securities Transfer Agent's Medallion Program (STAMP), the
Stock Exchange Medallion Program (SEMP) and the New York Stock Exchange
Medallion Signature Program (MSP) or any other "eligible guarantor institution,"
as that term is defined in Rule 17Ad-15 under the Exchange Act.

     If the certificates for Siliconix shares are registered in the name of a
person other than the person who signs the letter of transmittal, or if
certificates for unexchanged Siliconix shares are to be issued to a person other
than the registered holder(s), the certificates must be endorsed or accompanied
by appropriate stock powers, in either case signed exactly as the name or names
of the registered owner or owners appear on the certificates, with the
signature(s) on the certificates or stock powers guaranteed in the manner we
have described above.

     THE METHOD OF DELIVERY OF SILICONIX SHARE CERTIFICATES AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, IS AT YOUR OPTION AND RISK,
AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE
AGENT. IF DELIVERY IS BY MAIL, WE RECOMMEND REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO
ENSURE TIMELY DELIVERY.

     TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING WITH RESPECT TO CASH IN
LIEU OF A FRACTION OF A SHARE OF VISHAY COMMON STOCK RECEIVED PURSUANT TO THE
OFFER, YOU MUST PROVIDE THE EXCHANGE AGENT WITH

                                        37
   43

YOUR CORRECT TAXPAYER IDENTIFICATION NUMBER AND CERTIFY THAT YOU ARE NOT SUBJECT
TO BACKUP WITHHOLDING OF FEDERAL INCOME TAX BY COMPLETING THE SUBSTITUTE FORM
W-9 INCLUDED IN THE LETTER OF TRANSMITTAL. SOME STOCKHOLDERS (INCLUDING, AMONG
OTHERS, ALL CORPORATIONS AND SOME FOREIGN INDIVIDUALS) ARE NOT SUBJECT TO BACKUP
WITHHOLDING. IN ORDER FOR A FOREIGN INDIVIDUAL TO QUALIFY AS AN EXEMPT
RECIPIENT, THE STOCKHOLDER MUST SUBMIT A FORM W-8BEN, SIGNED UNDER PENALTIES OF
PERJURY, ATTESTING TO THAT INDIVIDUAL'S EXEMPT STATUS. ADDITIONAL INFORMATION
REGARDING BACKUP WITHHOLDING IS PROVIDED IN THE LETTER OF TRANSMITTAL.

WITHDRAWAL RIGHTS

     Siliconix shares tendered pursuant to the offer may be withdrawn at any
time prior to the applicable expiration date and, unless we have previously
accepted them pursuant to the offer, may also be withdrawn at any time after
July 23, 2001.

     For your withdrawal to be effective, the exchange agent must receive from
you a written, telex or facsimile transmission notice of withdrawal at one of
its addresses set forth on the back cover of this prospectus, and your notice
must include your name, address, social security number, the certificate
number(s) and the number of Siliconix shares to be withdrawn as well as the name
of the registered holder, if it is different from that of the person who
tendered those Siliconix shares. If Siliconix shares have been tendered pursuant
to the procedures for book-entry tender discussed under "Procedure for Tendering
Shares," any notice of withdrawal must specify the name and number of the
account at DTC to be credited with the withdrawn Siliconix shares and must
otherwise comply with DTC's procedures. If certificates have been delivered or
otherwise identified to the exchange agent, the name of the registered holder
and the serial numbers of the particular certificates evidencing the Siliconix
shares withdrawn must also be furnished to the exchange agent, as stated above,
prior to the physical release of the certificates. We will decide all questions
as to the form and validity (including time of receipt) of any notice of
withdrawal, in our sole discretion, and our decision shall be final and binding.

     An eligible institution must guarantee all signatures on the notice of
withdrawal unless the Siliconix shares have been tendered for the account of an
eligible institution.

     Neither we, the exchange agent, the information agent nor any other person
will be under any duty to give notification of any defects or irregularities in
any notice of withdrawal or will incur any liability for failure to give any
notification. Any Siliconix shares properly withdrawn will be deemed not to have
been validly tendered for purposes of our offer. However, you may retender
withdrawn Siliconix shares by following one of the procedures discussed under
"Procedure for Tendering Shares" or "Guaranteed Delivery" at any time prior to
the expiration date.

GUARANTEED DELIVERY

     If you wish to tender Siliconix shares pursuant to the offer and your
certificates are not immediately available or you cannot deliver the
certificates and all other required documents to the exchange agent prior to the
expiration date or cannot complete the procedure for book-entry transfer on a
timely basis, your Siliconix shares may nevertheless be tendered, so long as all
of the following conditions are satisfied:

     - you make your tender by or through an eligible institution;

     - a properly completed and duly executed notice of guaranteed delivery,
       substantially in the form made available by us, is received by the
       exchange agent as provided below on or prior to the expiration date; and

     - the certificates for all tendered Siliconix shares (or a confirmation of
       a book-entry transfer of such securities into the exchange agent's
       account at DTC as described above), in proper form for transfer, together
       with a properly completed and duly executed letter of transmittal (or a
       manually signed facsimile thereof), with any required signature
       guarantees (or, in the case of a book-entry transfer, an agent's message)
       and all other documents required by the letter of transmittal are
       received by the exchange agent within three Nasdaq National Market
       trading days after the date of execution of such notice of guaranteed
       delivery.
                                        38
   44

     You may deliver the notice of guaranteed delivery by hand or transmit it by
facsimile transmission or mail to the exchange agent and you must include a
guarantee by an eligible institution in the form set forth in that notice.

     In all cases, we will exchange Siliconix shares tendered and accepted for
exchange pursuant to our offer only after timely receipt by the exchange agent
of certificates for Siliconix shares (or timely confirmation of a book-entry
transfer of those Siliconix shares into the exchange agent's account at DTC as
described above), a properly completed and duly executed letter(s) of
transmittal (or a manually signed facsimile(s) thereof), or an agent's message
in connection with a book-entry transfer, and any other required documents.

EFFECT OF TENDER

     By executing a letter of transmittal as set forth above, you irrevocably
appoint our designees as your attorneys-in-fact and proxies, each with full
power of substitution, to the full extent of your rights with respect to your
Siliconix shares tendered and accepted for exchange by us and with respect to
any and all other Siliconix shares and other securities issued or issuable in
respect of the Siliconix shares on or after May 25, 2001. That appointment is
effective, and voting rights will be affected, when and only to the extent that
we deposit shares of Vishay common stock for Siliconix shares that you have
tendered with the exchange agent. All such proxies shall be considered coupled
with an interest in the tendered Siliconix shares and therefore shall not be
revocable. Upon the effectiveness of such appointment, all prior proxies that
you have given will be revoked, and you may not give any subsequent proxies
(and, if given, they will not be deemed effective). Our designees will, with
respect to the Siliconix shares for which the appointment is effective, be
empowered, among other things, to exercise all of your voting and other rights
as they, in their sole discretion, deem proper at any annual, special or
adjourned meeting of Siliconix's stockholders or otherwise. We reserve the right
to require that, in order for Siliconix shares to be deemed validly tendered,
immediately upon our exchange of those Siliconix shares, we must be able to
exercise full voting rights with respect to such Siliconix shares.

     We will determine questions as to the validity, form, eligibility
(including time of receipt) and acceptance for exchange of any tender of
Siliconix shares, in our sole discretion, and our determination shall be final
and binding. We reserve the absolute right to reject any and all tenders of
Siliconix shares that we determine are not in proper form or the acceptance of
or exchange for which may, in the opinion of our counsel, be unlawful. No tender
of Siliconix shares will be deemed to have been validly made until all defects
and irregularities in tenders of Siliconix shares have been cured or waived.
Neither we, the exchange agent, the information agent nor any other person will
be under any duty to give notification of any defects or irregularities in the
tender of any Siliconix shares or will incur any liability for failure to give
any such notification. Our interpretation of the terms and conditions of our
offer (including the letter of transmittal and instructions thereto) will be
final and binding.

     The tender of Siliconix shares pursuant to any of the procedures described
above will constitute a binding agreement between us and you upon the terms and
subject to the conditions of the offer.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

     The following discussion is a summary of the material U.S. federal income
tax consequences of the exchange of Siliconix common stock for Vishay common
stock in the offer and, if consummated, merger. The discussion which follows is
based on the U.S. Internal Revenue Code of 1986, as amended, treasury
regulations promulgated thereunder, administrative rulings and pronouncements
and judicial decisions as of the date hereof, all of which are subject to
change, possibly with retroactive effect. Any such change could alter the tax
consequences discussed in this document. The discussion below is also based on
representations made by Vishay and Vishay TEMIC. If any of these representations
is inaccurate, the tax consequences of the offer and merger could differ from
those described in this document.

     The discussion below is for general information only and, except where
specifically noted, does not address the effects of any state, local or non-U.S.
tax laws. In addition, the discussion below relates to
                                        39
   45

persons who hold Siliconix common stock and will hold Vishay common stock as
capital assets. The tax treatment of a Siliconix stockholder may vary depending
upon such stockholder's particular situation, and certain stockholders may be
subject to special rules not discussed below, including for example, partners of
partnerships that hold Siliconix common stock or will hold Vishay common stock,
insurance companies, tax-exempt organizations, financial institutions,
broker-dealers and individuals who received Siliconix common stock pursuant to
the exercise of employee stock options or otherwise as compensation. In
addition, this discussion does not address the tax consequences to any Siliconix
stockholder who is a not a U.S. Holder or who exercises appraisal rights.

     As used in this section, a "U.S. Holder" means a beneficial owner of
Siliconix common stock who exchanges Siliconix common stock for Vishay common
stock and who is, for U.S. federal income tax purposes:

     - a citizen or resident of the U.S.;

     - a corporation, partnership or other entity, other than a trust, created
       or organized in or under the laws of the U.S. or any political
       subdivision thereof;

     - an estate whose income is subject to U.S. federal income tax regardless
       of its source; or

     - a trust:

      1. if, in general, a court within the U.S. is able to exercise primary
         supervision over its administration and one or more U.S. persons have
         authority to control all of its substantial decisions, or

      2. that has a valid election in effect under applicable U.S. treasury
         regulations to be treated as a U.S. person.

     In the opinion of Kramer Levin Naftalis & Frankel LLP, based upon
representations made by Vishay and Vishay TEMIC and on certain assumptions set
forth in such opinion and as further qualified therein, (i) the exchange of
Siliconix common stock for Vishay common stock in the offer and, if consummated,
merger will constitute a reorganization within the meaning of Section 368(a) of
the U.S. Internal Revenue Code and (ii) Vishay, Vishay TEMIC and Siliconix will
each be a party to the reorganization. As a result:

     - Siliconix stockholders will not recognize any income, gain or loss on the
       exchange of Siliconix common stock for Vishay common stock in the offer
       and/or merger (except for cash received in lieu of fractional shares);

     - the tax basis to a Siliconix stockholder of the Vishay common stock
       received in exchange for Siliconix common stock pursuant to the offer
       and/or merger, including any fractional share interest in Vishay common
       stock for which cash is received, will equal such Siliconix stockholder's
       tax basis in the Siliconix common stock surrendered in exchange therefor;

     - the holding period of a Siliconix stockholder for the Vishay common stock
       received pursuant to the offer and/or merger will include the holding
       period of the Siliconix common stock surrendered in exchange therefor;

     - a Siliconix stockholder who receives cash in lieu of a fractional share
       of Vishay common stock pursuant to the offer and/or merger will be
       treated as having received such cash in redemption of such fractional
       share interest and generally will recognize capital gain or loss on such
       deemed exchange in an amount equal to the difference between the amount
       of cash received and the basis of the Siliconix stock allocable to such
       fractional share; and

     - no income, gain or loss will be recognized by Vishay, Vishay TEMIC or
       Siliconix as a result of the transfer to Siliconix stockholders of the
       Vishay common stock provided by Vishay to Vishay TEMIC pursuant to the
       offer and merger.

PURPOSE OF THE OFFER; THE MERGER; APPRAISAL RIGHTS

     We are making the offer in order to acquire all of the outstanding shares
of Siliconix common stock that we do not own. Our offer is conditioned on, among
other things, the tender of at least a majority of the outstanding publicly held
Siliconix shares. If that condition is satisfied and if the offer is
consummated, we will own more than 90% of the outstanding common stock of
Siliconix. Under Delaware law, this would allow us to effect a "short-form"
merger of Siliconix with the subsidiary of Vishay holding the Siliconix shares
without stockholder approval. We currently intend, as soon as practicable after
consummation of the offer, to effect such a short-form merger, with the
surviving company becoming a wholly-owned subsidiary of Vishay. To effect the
merger, Vishay TEMIC would contribute all of the shares of Siliconix common
stock to a wholly-owned subsidiary of Vishay TEMIC and that subsidiary would
merge with and into Siliconix.

     If the short-form merger takes place and you have not validly tendered your
Siliconix shares in the offer, your shares will be exchanged for the same
consideration per Siliconix share you own that you would have received, without
interest, if you had tendered your shares in the offer, unless you properly
perfect your appraisal rights under Delaware law.

     Although we currently intend to effect the short-form merger following
consummation of the offer, we are not required to do so and there are
circumstances in which we may determine not to effect the merger. These
circumstances include if a court prevented us from effecting the merger or if we
deemed it advisable not to effect the merger in order to settle litigation or
avoid litigation risks. If we determine not to effect the short-form merger
following consummation of the offer, we could still do so at a later time. In
that case, the value of the per share consideration received by stockholders in
the merger could be less than or greater than the value of the consideration
received in the offer.

     If we were to consummate the offer but not effect the short-form merger,
the liquidity of and market for the remaining publicly held Siliconix shares,
and the rights of the holders of those shares, could be adversely affected. The
Siliconix common stock is currently listed on the Nasdaq National Market System.
Depending upon the number of Siliconix shares purchased in the offer, the
Siliconix common stock may no longer meet the requirements for continued listing
and may be delisted from the Nasdaq National Market System. It is possible that
the Siliconix common stock would continue to trade in the over-the-counter
market and that price quotations would be reported by other sources. The extent
of the public market for the Siliconix stock and the availability of such
quotations would, however, depend upon the number of holders of the Siliconix
stock remaining at such time, the interests in maintaining a market in the
Siliconix stock on the part of securities firms, the possible termination of
registration of the Siliconix stock under the Exchange Act, as described below,
and other factors.

     The Siliconix common stock is currently registered under the Exchange Act.
This registration may be terminated upon application of Siliconix to the SEC if
there are fewer than 300 holders of record of the Siliconix stock. The
termination of the registration of the Siliconix common stock under the Exchange
Act would substantially reduce the information required to be furnished by
Siliconix to its stockholders and to the SEC. It would also make certain of the
provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b), the requirement of furnishing a proxy statement in
connection with stockholders' meetings, the related requirement of an annual
report to stockholders, and the requirements of Rule 13e-3 with respect to going
private transactions, no longer applicable.

     The shares of Siliconix common stock are currently "margin securities"
under the regulations of the Board of Governors of the Federal Reserve System.
This has the effect, among other things, of allowing brokers to extend credit on
the Siliconix common stock as collateral. Depending on factors similar to those
described above regarding listing and market quotations, it is possible the
Siliconix stock would no longer constitute "margin securities" for purposes of
the Federal Reserve Board's margin regulations. If registration of the Siliconix
common stock under the Exchange Act were terminated, the Siliconix stock would
no longer be "margin securities."

  APPRAISAL RIGHTS

     Under Delaware law, Siliconix stockholders do not have appraisal rights in
connection with the offer. The following summarizes provisions of Delaware law
regarding appraisal rights that would be applicable in the event of a short-form
merger. This discussion is qualified in its entirety by reference to Section 262
of the Delaware General Corporation Law, which contains the Delaware appraisal
statute. A copy of this provision is attached to this document as Annex A. If
you fail to take any action required by Delaware law, your rights to an
appraisal will be waived or terminated.

  Notification of Merger's Effectiveness

     Either before the effective time of the merger or within ten days
thereafter, Siliconix will send notice of the effectiveness of the merger and
the availability of appraisal rights to each Siliconix stockholder (other than
Vishay or its subsidiaries).

  Electing Appraisal Rights

     To exercise appraisal rights, the record holder of Siliconix common stock
must within 20 days after the date of mailing of such notice deliver a written
demand for appraisal to Siliconix. This demand must reasonably inform Siliconix
of the identity of the holder of record and that the stockholder demands
appraisal of his, her or its shares of Siliconix common stock.

     A demand for appraisal must be delivered to: Corporate Secretary, Siliconix
incorporated, 2201 Laurelwood Road, Santa Clara, California 95054.

  Only Record Holders May Demand Appraisal Rights

     Only a record holder of Siliconix common stock is entitled to demand
appraisal rights. The demand must be executed by or for the record holder, fully
and correctly, as the holder's name appears on the holder's stock certificates.

     - If the Siliconix common stock is owned of record in a fiduciary capacity,
       such as by a trustee, guardian or custodian, the demand should be
       executed in that capacity.

     - If the Siliconix common stock is owned of record by more than one person,
       as in a joint tenancy or tenancy in common, the demand should be executed
       by or for all owners.

     - An authorized agent, including one of two or more joint owners, may
       execute the demand for appraisal for a holder of record. The agent must
       identify the owner or owners of record and expressly disclose the fact
       that, in executing the demand, the agent is acting as agent for the owner
       or owners of record.

     - A holder of record, such as a broker, who holds common stock as nominee
       for beneficial owners, may exercise a holder's right of appraisal with
       respect to common stock held for all or less than all of such beneficial
       owners. In that case, the written demand should set forth the number of
       shares of common stock covered by the demand. If no number of shares of
       common stock is expressly mentioned, the demand will be presumed to cover
       all shares of common stock standing in the name of the record holder.

  Court Petition Must Be Filed

     Within 120 days after the effective time of the merger, the surviving
corporation in the merger or any stockholder who has satisfied the foregoing
conditions may file a petition in the Delaware Court of Chancery demanding a
determination of the fair value of the Siliconix common stock. Stockholders
seeking to exercise appraisal rights should initiate all necessary action to
perfect its rights within the time periods prescribed by Delaware law.

                                        42
   48

  Appraisal Proceeding by Delaware Court

     If a petition for an appraisal is timely filed, after a hearing on the
petition, the Delaware Court of Chancery will determine which of the
stockholders are entitled to appraisal rights. The court will appraise the
common stock owned by the stockholders and determine its fair value. In
determining fair value, the court may consider a number of factors including
market values of Siliconix's stock, asset values and other generally accepted
valuation considerations, but will exclude any element of value arising from the
accomplishment and expectation of the merger. The court will also determine the
amount of interest, if any, to be paid upon the value of the common stock to the
stockholders entitled to appraisal.

     The value determined by the court for Siliconix common stock could be more
than, less than, or the same as the merger consideration, but the form of the
consideration payable as a result of the appraisal proceeding would be cash. The
court may also order that all or a portion of any stockholder's expenses
incurred in connection with an appraisal proceeding, including reasonable
attorney's fees and expenses and reasonable fees and expenses of experts
utilized in the appraisal proceeding, be charged against the value of all common
stock entitled to appraisal.

  Effect of Appraisal Demand on Voting and Right to Dividends

     Any stockholder who has duly demanded an appraisal in compliance with
Delaware law will not, after the effective time of the merger, be entitled to
vote the shares subject to the demand for any purpose. The shares subject to the
demand will not be entitled to dividends or other distributions, other than
those payable or deemed to be payable to stockholders of record as of a date
prior to the effective time.

  Loss, Waiver or Withdrawal of Appraisal Rights

     Holders of Siliconix common stock lose the right to appraisal if no
petition for appraisal is filed within 120 days after the effective time of the
merger. A stockholder will also lose the right to an appraisal by delivering to
the surviving corporation a written withdrawal of such stockholder's demand for
an appraisal. In addition, any attempt to withdraw that is made more than 60
days after the effective time requires the written approval of the surviving
corporation. If appraisal rights are not perfected or a demand for appraisal
rights is timely withdrawn, a stockholder will be entitled to receive the
consideration otherwise payable pursuant to the merger, without interest. The
number of shares of Vishay common stock, and cash in lieu of a fraction of a
share of Vishay common stock, delivered to such stockholder will be based on the
same exchange ratio utilized in the offer and the merger, regardless of the
market price of Vishay shares at the time of delivery.

  Dismissal of Appraisal Proceeding

     If an appraisal proceeding is timely instituted, such proceeding may not be
dismissed as to any stockholder who has perfected a right of appraisal without
the approval of the court.

CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS

     General. Except as set forth herein, we are not aware of any license or
regulatory permit that appear to be material to the business of Siliconix and
its subsidiaries, taken as a whole, that might be materially adversely affected
by our acquisition of Siliconix shares, or of any filing approval or other
action by or with any governmental entity or administrative or regulatory agency
that would be required for our acquisition or ownership of Siliconix shares.
Should any such approval or other action be required, we presently contemplate
that such approval or other action will be sought. While, except as otherwise
described in this prospectus, we do not presently intend to delay the acceptance
for payment of, or payment for, shares tendered pursuant to the offer pending
the outcome of any such matter, there can be no assurance that any such approval
or other action, if needed, would be obtained or would be obtained without
substantial conditions or that failure to obtain any such approval or other
action might not result in consequences adverse to Siliconix's business or that
certain parts of Siliconix's business might not have to be disposed of, or other
substantial conditions complied with, in the event that such approvals were not
obtained or such other actions were not taken or in order to obtain any such
approval or other action. We intend to make all required filings under the
Exchange Act.

     State Takeover Laws. A number of states have adopted takeover laws and
regulations which purport, to varying degrees, to be applicable to attempts to
acquire securities of corporations which are incorporated in such states or
which have substantial assets, stockholders, principal executive offices or
principal places of business therein. We have not attempted to comply with any
state takeover statutes in connection with the offer. We reserve the right to
challenge the validity or applicability of any state law allegedly applicable to
the offer, and nothing in this prospectus nor any action taken in connection
herewith is intended as a waiver of that right. In the event that it is asserted
that one or more takeover statutes apply to the offer, and it is not determined
by an appropriate court that such statute or statutes do not apply or are
invalid as applied to the offer, as applicable, we may be required to file
certain documents with, or receive approvals from, the relevant state
authorities, and we might be unable to accept for payment or purchase shares
tendered pursuant to the offer or be delayed in continuing or consummating the
offer. In such case, we may not be obligated to accept for purchase, or pay for,
any shares tendered. See "Other Conditions of the Offer" above.

     Siliconix is incorporated under the laws of the State of Delaware. In
general, Section 203 of the DGCL prevents an "interested stockholder" (including
a person who owns or has the right to acquire 15% or more of a corporation's
outstanding voting stock) from engaging in a "business combination" (defined to
include mergers and certain other actions) with a Delaware corporation for a
period of three years following the time such person becomes an interested
stockholder unless, among other exceptions, the "business combination" is
approved by the board of directors of such corporation prior to such time.
Vishay has held its interest in Siliconix for more than three years, so Section
203 of the DGCL should not apply to this offer or the merger.

     Non-U.S. Approvals. We are unaware of any requirement for the filing of
information with, or the obtaining of the approval or consent of, governmental
authorities in any non-U.S. jurisdiction that is applicable to the offer or the
merger.

CERTAIN EFFECTS OF THE OFFER

     Effects on the Market. We intend to cause the delisting of the Siliconix
shares from Nasdaq following consummation of the offer and the short-form
merger. See "Purpose of the Offer; The Merger; Appraisal Rights" for a
discussion of the possibility that the Siliconix common stock could be delisted
from Nasdaq if the offer is consummated but the merger is not effected.

     Exchange Act Registration. The shares of Siliconix common stock are
currently registered under the Exchange Act. If the offer and the merger are
consummated, we will terminate registration of the Siliconix shares under the
Exchange Act. See "Purpose of the Offer; The Merger; Appraisal Rights" for a
discussion of the possibility that the Siliconix common stock could be
deregistered under the Exchange Act if the offer is consummated but the merger
is not effected.

     Financing of the Offer. The securities required to consummate the offer
come from Vishay's authorized but unissued shares. Vishay's fees and expenses in
connection with the offer are estimated to be approximately $300,000, including
the SEC filing fee and the fees of the information agent, the exchange agent,
the financial printer, counsel, auditors and other professionals. We will obtain
all of such funds from Vishay's available capital resources.

     Going Private Transactions. The SEC has adopted Rule 13e-3 under the
Exchange Act which is applicable to certain "going private" transactions and
which may under certain circumstances be applicable to the purchase of Siliconix
shares pursuant to an offer in which Vishay seeks to acquire the remaining
shares not held by Vishay or its subsidiaries. Rule 13e-3 requires, among other
things, that certain financial information concerning the target and certain
information relating to the fairness of the proposed transaction and the
consideration offered to minority stockholders in such transaction be filed with
the SEC and disclosed to stockholders prior to consummation of the transaction.
We believe that Rule 13e-3 will not be applicable to the offer and the merger
pursuant to Rule 13e-3(g)(2) under the Exchange Act, because the stockholders of
Siliconix will be receiving common stock of Vishay that is registered under the
Exchange Act and listed on the NYSE.

     Plans for Siliconix. Siliconix's products are currently marketed through
Vishay's worldwide distribution system. Following the consummation of the offer
and the merger, we expect to initiate a review of Siliconix and its assets,
corporate structure, capitalization, operations, properties, policies,
management and personnel. As a result of this review, we may determine to make
changes in the business of Siliconix to better organize, integrate and
coordinate the activities of Siliconix and Vishay. We may in the future also
consider transactions such as the disposition or acquisition of material assets,
alliances, joint ventures, other forms of co-operation with third parties or
other extraordinary transactions affecting Siliconix or its operations.

RELATIONSHIPS WITH SILICONIX

     In considering whether to tender your shares in the offer, you should be
aware of certain transactions between Vishay and Siliconix since the end of 1997
in addition to those referred to above in "Background of the Offer."

     At December 31, 1997, Siliconix owed $34,570,000 to Daimler-Benz Capital,
Inc., then an affiliated company. After the acquisition of approximately 80.4%
of Siliconix's outstanding common stock by Vishay in March 1998, this
indebtedness was assigned to Vishay. It bore interest at a floating rate equal
to Vishay's cost of funds, approximately 6.25% per annum, and was paid in full
in 1999.

     Effective May 1998, Siliconix signed a revolving intercompany promissory
note payable to Vishay establishing a $35,000,000 revolving credit facility.
Under the note, Siliconix may borrow up to $35,000,000 from time to time from
Vishay for general corporate purposes. Amounts borrowed bore interest at a
floating rate equal to Vishay's cost of funds, approximately 6.25% per annum.
The maximum amount outstanding under this note was $14,300,000, which amount was
paid in full in 1999. There is currently no amount outstanding under the note.

     Effective May 1998, Siliconix borrowed $16,000,000 from Vishay. The purpose
of this loan was to enable Siliconix Technology C.V., an affiliated limited
partnership, to purchase 40% of the outstanding equity interest in Shanghai
Simconix Co. Ltd. from the Shanghai Institute of Metallurgy. Shanghai Simconix
is a joint venture between Siliconix and the Shanghai Institute of Metallurgy
that performs assembly and test services for Siliconix in Shanghai, China. This
indebtedness bore interest at a floating rate equal to Vishay's cost of funds,
approximately 6.25% per annum. This indebtedness was paid in full in 1999.

     Effective December 1999, Vishay signed a revolving intercompany promissory
note payable to Siliconix establishing a $75,000,000 revolving credit facility.
Under the note, Vishay may borrow up to $75,000,000 from time to time from
Siliconix for general corporate purposes. Amounts borrowed bear interest at a
floating rate equal to Siliconix's cost of funds, currently 7.5% per annum. We
believe that this

                                        46
   52

is a higher rate of return for Siliconix than Siliconix could obtain from most
traditional short-term investments. The maximum amount outstanding under this
note was $37,000,000, which was paid in full in 2000.

     Except as set forth in this prospectus, neither we nor, to the best of our
knowledge, any of our directors, executive officers or other affiliates (a) has
any contract, arrangement, understanding or relationship with any other person
with respect to any securities of Siliconix, including, but not limited to, any
contract, arrangement, understanding or relationship concerning the transfer or
the voting of any securities of Siliconix, joint ventures, loan or option
arrangements, puts or calls, guaranties of loans, guaranties against loss, or
the giving or withholding of proxies, (b) has engaged in contacts, negotiations
or transactions with Siliconix or its affiliates concerning a merger,
consolidation, acquisition, tender offer or other acquisition of securities,
election of directors or a sale or other transfer of a material amount of assets
or (c) has had any other transaction with Siliconix or any of its executive
officers, directors or affiliates that would require disclosure under the rules
and regulations of the SEC applicable to the offer. Except for the shares of
Siliconix common stock that we own as disclosed in this prospectus, neither we
nor any of our affiliates beneficially own any Siliconix shares or have effected
any transaction in the shares within the past 60 days.

ACCOUNTING TREATMENT

     The merger will be accounted for at historical costs, with the exception of
the Siliconix minority interest which will be accounted for under the purchase
method of accounting in accordance with United States generally accepted
accounting principles. Accordingly, the cost to acquire the Siliconix minority
interest in excess of its carrying value will be allocated on a pro rata basis
to the assets acquired and liabilities assumed based on their fair values, with
any excess being allocated to goodwill. A final determination of the intangible
asset lives and required purchase accounting adjustments, including the
allocation of the purchase price to the assets acquired and liabilities assumed
based on their respective fair values, has not yet been made.

     The acquisition of the Siliconix common stock would not be considered
material to Vishay and, accordingly, Vishay is not required to include pro forma
financial information in this prospectus, except as provided in "Comparative Per
Share Information" on page 21.

FEES AND EXPENSES

     We have retained MacKenzie Partners, Inc. as information agent in
connection with the offer. The information agent may contact holders of
Siliconix shares by mail, telephone, telex, telegraph and personal interview and
may request brokers, dealers and other nominee stockholders to forward material
relating to the offer to beneficial owners of Siliconix shares. We will pay the
information agent customary fees for these services in addition to reimbursing
the information agent for its reasonable out-of-pocket expenses. We have agreed
to indemnify the information agent against certain liabilities and expenses in
connection with the offer, including certain liabilities under the U.S. federal
securities laws.

     In addition, we have retained American Stock Transfer & Trust Company as
the exchange agent. We will pay the exchange agent reasonable and customary fees
for its services in connection with the offer, will reimburse the exchange agent
for its reasonable out-of-pocket expenses and will indemnify the exchange agent
against certain liabilities and expenses, including certain liabilities under
the U.S. federal securities laws.

     Except as set forth above, we will not pay any fees or commissions to any
broker, dealer or other person for soliciting tenders of Siliconix shares
pursuant to the offer. We will reimburse brokers, dealers, commercial banks and
trust companies and other nominees, upon request, for customary clerical and
mailing expenses incurred by them in forwarding offering materials to their
customers.

                          INTERESTS OF CERTAIN PERSONS

     In considering whether to tender your shares in the offer, you should be
aware of interests of certain persons as described below in connection with the
offer and the merger.

     Each of Mr. Everett Arndt, Ms. Lori Lipcaman and Mr. Glyndwr Smith,
directors of Siliconix, are management employees of Vishay and Michael
Rosenberg, also a director of Siliconix, has been an independent consultant to
Vishay since 1992.

     Until 1999, Mr. Mark Segall, a director of Siliconix and member of the
special committee, was a partner with the law firm of Kramer Levin Naftalis &
Frankel LLP during which time he represented Vishay as its corporate counsel and
represented Vishay in the transaction in which it first acquired its interest in
Siliconix. In addition, Mr. Segall was listed as Vishay's representative,
attorney or required recipient of any notice on various of Vishay's SEC filings
and corporate documents.

     Mr. Timothy V. Talbert, a director of Siliconix and member of the special
committee, was employed by Manufacturers Bank during the mid-1980s. During his
tenure with the bank, Mr. Talbert provided many banking services to Vishay and
served as relationship manager for Vishay. Also while with the bank, Mr. Talbert
helped arrange financing for one of Vishay's acquisitions and worked personally
with Dr. Felix Zandman, the chief executive officer of Vishay, in connection
with such acquisition. Mr. Talbert and his wife have held 2,014 shares of Vishay
stock in individual retirement accounts for over ten years.

     Siliconix does not maintain a stock option plan or stock purchase plan of
its own. Certain Siliconix executive officers have received options to purchase
Vishay common stock under Vishay's 1998 Stock Option Plan or other plans. King
Owyang, the president and chief executive officer of Siliconix, owns options to
purchase 102,500 shares of Vishay common stock.

     The cost savings and possible financial improvements resulting from a
combination of Siliconix and Vishay could benefit Siliconix's management, who
might receive increased compensation, and the directors of Siliconix affiliated
with Vishay, by virtue of the benefits of the transaction to Vishay.

           COMPARISON OF RIGHTS OF HOLDERS OF SILICONIX COMMON STOCK
                       AND HOLDERS OF VISHAY COMMON STOCK

     Because Siliconix and Vishay are both organized under the laws of the State
of Delaware, the differences in the rights of a Siliconix stockholder and the
rights of a Vishay stockholder arise solely from differences in the
organizational documents of Siliconix and Vishay, rather than from differences
of law. The following summary highlights material differences between the
current rights of holders of Vishay common stock and holders of Siliconix common
stock. This summary does not purport to be a complete discussion of the
certificates of incorporation and by-laws of Siliconix and Vishay and is
qualified in its entirety by reference to these documents. Copies of each
company's certificate of incorporation and by-laws have been filed with the SEC
and will be sent to holders of Siliconix common stock upon request. See "Where
You Can Find More Information" on page 1.

                                               shares of stock of the corporation are owned

                                               stockholders, the number of directors may be

                                               of such stockholders. Subject to the
                                               foregoing limitation, the number of directors
                                               may be fixed from time to time by action of
                                               the stockholders or of the directors, or, if
                                               the number is not fixed, the number shall be

                                    ANNEX A

        SECTION 262 OF GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

SEC. 262 APPRAISAL RIGHTS.

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 264 of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

                                       A-1
   64

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only to be sent to each stockholder who is entitled to appraisal
     rights and who has demanded appraisal of such holder's shares in accordance
     with this subsection. An affidavit of the secretary or assistant secretary
     or of the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated
                                       A-2
   65

     therein. For purposes of determining the stockholders entitled to receive
     either notice, each constituent corporation may fix, in advance, a record
     date that shall be not more than 10 days prior to the date the notice is
     given, provided, that if the notice is given on or after the effective date
     of the merger or consolidation, the record date shall be such effective
     date. If no record date is fixed and the notice is given prior to the
     effective date, the record date shall be the close of business on the next
     day preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has
                                       A-3
   66

submitted his certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that he is not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                PART II. INFORMATION NOT REQUIRED IN PROSPECTUS



ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS



     Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent of
the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, in any criminal proceeding, if such person
had no reasonable cause to believe his conduct was unlawful; provided that, in
the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent that the adjudicating court determines that such indemnification is
proper under the circumstances.



     Vishay's certificate of incorporation provides that every person who is or
was a director, officer, employee or agent of the corporation shall be
indemnified by the corporation against all judgments, payments in settlement,
fines, penalties, and other reasonable costs and expenses resulting from any
action, proceeding, investigation or claim which is brought or threatened by or
in the right of Vishay or by anyone else by reason of such person being or
having been a director, officer, employee or agent of Vishay or any act or
omission of such person in such capacity. Such indemnification shall be
available either if such person is wholly successful in defending such action or
if, in the judgment of a court or the Board of Directors or in the opinion of
independent legal counsel, such person acted in good faith in what he reasonably
believed to be in the best interests of the corporation and was not adjudged
liable to the corporation, and, in any criminal action, had no reasonable cause
to believe that his action was unlawful. In the case of a derivative action,
such indemnification shall not be made other than in respect of a court approved
settlement or if, in the opinion of independent counsel, the person satisfied
the standard of conduct specified in the prior sentence, the action was without
substantial merit, the settlement was in the best interest of Vishay and the
payment is permissible under applicable law. Directors may authorize the
advancement of reasonable costs and expenses in connection with any such action
to the extent permitted under Delaware law.



     The Vishay certificate of incorporation further provides that no director
shall have any personal liability to Vishay or to its stockholders for any
monetary damages for breach of fiduciary duty, to the extent permitted under the
Delaware General Corporation Law.



     Vishay maintains $55 million of insurance to reimburse the directors and
officers of Vishay and its subsidiaries, for charges and expenses incurred by
them for wrongful acts claimed against them by reason of their being or having
been directors or officers of Vishay or any of its subsidiaries. Such insurance
specifically excludes reimbursement of any director or officer for any charge or
expense incurred in connection with various designated matters, including libel
or slander, illegally obtained personal profits, profits recovered by Vishay
pursuant to Section 16(b) of the Exchange Act and deliberate dishonesty.

  ITEM 22. UNDERTAKINGS



     The undersigned Registrant hereby undertakes:



          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:



             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act;



             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this registration statement (or most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the maximum aggregate offering price
        may be reflected in the form of a prospectus filed with the SEC pursuant
        to Rule 424(b) under the Securities Act, if in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and



             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this registration statement
        or any material change to such information in this registration
        statement;



          (2) That, for the purposes of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof; and



          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.


                                       II-3
   71


     The Registrant undertakes that, for purposes of determining any liability
under the Securities Act, each filing of the Registrant's annual report pursuant
to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Exchange Act) that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.



     The Registrant undertakes that prior to any public offering of the
securities registered hereunder through use of a prospectus which is a part of
this registration statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c), such offering prospectus will
contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other items of the applicable form.



     The Registrant undertakes that every prospectus: (i) that is filed pursuant
to the paragraph immediately preceding, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act and is used in connection
with an offering of securities subject to Rule 415, will be filed as a part of
an amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.



     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.



     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.



     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
