                      Expires Without Acceptance of Shares;
                         Minimum Condition Not Satisfied

      MALVERN, Pa.--July 6, 2001--Vishay Intertechnology, Inc. (NYSE: VSH)
announced that its offer to exchange shares of its common stock for the shares
of common stock of Siliconix incorporated (NASDAQ: SILI) not already owned by
Vishay expired at 5:00 p.m., New York City time on Thursday, July 5, 2001
without the acceptance of the tendered shares.

      It was a non-waivable condition of the offer that there be validly
tendered and not withdrawn a majority of the shares of Siliconix not already
owned by Vishay. This condition was not satisfied. According to the American
Stock Transfer & Trust Company, the exchange agent for the offer, 2,347,200
Siliconix shares were tendered, constituting approximately 40% of the 5,849,040
shares not owned by Vishay.

      Commenting on the results of the offer, Dr. Felix Zandman, chairman and
chief executive officer of Vishay, said: "We conditioned our offer for Siliconix
on the tender of a majority of the publicly held shares so that the public
stockholders of Siliconix would decide whether Siliconix should be taken private
at this time. Stockholders owning a majority of the public shares did not
tender, and we respect their decision. Vishay reserves the right, from time to
time, to purchase Siliconix shares in the open market or in privately negotiated
transactions, subject of course to applicable securities laws."
