     WE ARE THE HOLDER OF RECORD (DIRECTLY OR INDIRECTLY) OF SILICONIX SHARES
HELD FOR YOUR ACCOUNT. A TENDER OF SUCH SILICONIX SHARES CAN BE MADE ONLY BY US
AS THE HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE ENCLOSED LETTER
OF TRANSMITTAL IS FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE USED

     We request instructions as to whether you wish us to tender any or all of
the Siliconix Shares held by us for your account, upon the terms and subject to
the conditions set forth in the Offer.

     Your attention is invited to the following:

     2. The Offer is being made for all outstanding Siliconix Shares.

     5. Cash will be paid in lieu of any fraction of a Vishay Common Share to
        which a stockholder would be entitled. Stockholders who fail to complete
        and sign the Substitute Form W-9 may be subject to a required federal
        backup withholding tax of 31% of any cash payment to such stockholder or
        other payee pursuant to the Offer.

     The Offer is made solely by the Prospectus and the related Letter of
Transmittal and any supplements and amendments thereto. Vishay TEMIC is not
aware of any state in which the making of the Offer or the acceptance of
Siliconix Shares pursuant to the Offer is prohibited by administrative or
judicial action pursuant to any valid state statute. If Vishay TEMIC becomes
aware of any valid state statute prohibiting the making of the Offer or the
acceptance of Siliconix Shares pursuant to the Offer, Vishay TEMIC will make a
good faith effort to comply with any such state statute. If, after such good
faith effort, Vishay TEMIC cannot comply with any such state statute, the Offer
will not be made to (nor will tenders be accepted from or on behalf of) the
holders of Siliconix Shares residing in any such jurisdiction. In any
jurisdiction in which the securities, blue sky or other laws require the Offer
to be made by a licensed broker or dealer, the Offer will be deemed to be made
on behalf of Vishay TEMIC by one or more registered brokers or dealers licensed
under the laws of such jurisdiction.

     If you wish to have us tender any or all of your Siliconix Shares, please
so instruct us by completing, executing and returning to us the instruction form
set forth on the reverse side of this letter. An envelope to return your
instruction form to us is enclosed. If you authorize the tender of your
Siliconix Shares, all your Siliconix Shares will be tendered unless otherwise
specified on the reverse side of this letter. YOUR INSTRUCTIONS SHOULD BE
FORWARDED TO US IN SUFFICIENT TIME TO PERMIT US TO SUBMIT A TENDER ON YOUR
BEHALF PRIOR TO THE EXPIRATION DATE.
