                     CUSIP NUMBERS: 928298AC2 AND 928298AD0

                  PURSUANT TO COMPANY NOTICE DATED MAY 5, 2004

                                                                     May 5, 2004

To Our Clients:

    Enclosed for your consideration is a company notice, dated May 5, 2004,
relating to the purchase of Liquid Yield Option'TM' Notes due 2021 (Zero
Coupon-Subordinated) (LYONs)* of VISHAY INTERTECHNOLOGY, INC., at the option of
the holders of the LYONs. A related purchase notice and a notice of withdrawal
are also enclosed.

    The option is pursuant to the terms and conditions specified in paragraph 7
of the LYONs, the indenture dated June 4, 2001 that governs the LYONs and the
company notice. Under these terms and conditions, Vishay will pay to holders who
validly exercise the option a purchase price of $602.77 per $1,000 principal
amount at maturity of the LYONs, on the purchase date of June 4, 2004. The
purchase price will be paid in the form of shares of common stock, except as set
forth below. Each holder of LYONs that exercises the option will receive a
number of shares determined by dividing the total amount of cash the holder
would have been entitled to receive had the purchase price been paid in cash by
the market price of a share of common stock. Market price for these purposes
means the average of the closing prices of Vishay common stock in New York Stock
Exchange composite trading for the five trading day period ending on the third
business day prior to the purchase date, which is the period from May 25, 2004
to and including June 1, 2004. However, Vishay's right to pay the purchase price
in stock is subject to a number of conditions, as described in the company
notice. If these conditions are not satisfied prior to the close of business on
the purchase date, Vishay will be obligated to pay the entire purchase price in
cash. Holders may specify in the purchase notice whether in these circumstances
they elect to withdraw exercise of the option with respect to some or all of
their LYONs or to receive cash.

    In order to exercise the option and receive the purchase price for their
LYONs, holders must --

     deliver and not withdraw a purchase notice (or an agent's message according
     to the procedures of The Depository Trust Company (DTC) for book-entry
     transfer) prior to 5:00 p.m. New York City time on June 3, 2004, the
     business date prior to the purchase date; and

     surrender the LYONs (together with any required documentation) to the
     paying agent prior to, on or after the purchase date, in conformity in all
     respects to the description of the LYONs in the purchase notice.

The paying agent for the exercise of the option is The Bank of New York.

    The enclosed materials are being forwarded to you as the beneficial owner of
LYONs held by us for your account. The option with respect that the LYONs that
we hold for you may be exercised only by us pursuant to your instructions. The
enclosed purchase notice is furnished to you for your information only and
cannot be used by you to exercise the option. Accordingly, we request
instructions as to whether you wish us to exercise the option with respect to
the LYONs that we hold for your account. We also request instruction whether, if

the option price cannot be paid in shares of Vishay common stock, you elect to
withdraw exercise of the option with respect to some or all of your LYONs or to
receive cash.

    Your prompt action is requested. The option will expire at 5:00 p.m., New
York City time on June 3, 2004, the day before the purchase date, and will not
be extended. If you want us to exercise the option on your behalf, you must give
us your instructions on a timely basis so that we may do so in advance of the
time of expiration of the option.

    The exercise of the option with respect to any LYONs may be withdrawn at any
time prior to 5:00 p.m., New York City time on June 3, 2004. The enclosed notice
of withdrawal is furnished to you for your information only and cannot be used
by you to withdraw exercise of the option. If, after instructing us to exercise
the option on your behalf, you want us to withdraw the exercise, either in whole
or in part, you must give us a timely instruction to that effect.

    If you want us to exercise the option with respect to any of your LYONs,
please so instruct us by completing, executing and returning to us the
instruction form on the next page of this letter. If you authorize exercise of
the option with respect to your LYONs, we will exercise the option with respect
