Vishay Commences Offer to Exchange 2.90 Vishay Shares For Each
Siliconix Share 


MALVERN, Pa., April 12  /PRNewswire-FirstCall/ -- Vishay Intertechnology, Inc.
(NYSE:VSH) announced today that it has commenced an offer to exchange 2.90
shares of its common stock for each share of common stock of Siliconix
incorporated (NASDAQ:SILI) not owned by Vishay.  Cash will be paid in lieu of
fractional shares of Vishay.  Vishay currently owns approximately 80.4% of the
outstanding shares of Siliconix.  The offer expires at 5:00 p.m., New York City
time, on Thursday, May 12, 2005, unless extended.

The offer is conditioned on there being validly tendered and not withdrawn a
majority of the outstanding shares of Siliconix not owned by Vishay.  There are
29,879,040 shares of Siliconix stock outstanding, of which 5,849,040 are
publicly held.  There are also other conditions to the offer.  Also, following
the consummation of the offer, unless prohibited by a court or there is
litigation pending seeking this prohibition, Vishay will promptly effect a
merger of Siliconix with a subsidiary of Vishay.  In this merger, all remaining
holders of Siliconix stock would receive the same consideration for their
shares as the holders who tendered their shares received in the offer. Vishay
has not entered into any agreement with Siliconix with respect to the offer.

Vishay previously announced its intention to make the offer on March 3, 2005
with an exchange ratio of 2.64 Vishay common shares for each Siliconix share. 
During the period following this announcement, the ratio of the market prices
for Siliconix shares and Vishay common shares has been in excess of this ratio.
 Also, during this period, several institutional investors who hold shares of
Vishay and Siliconix communicated to Vishay management that they would expect
to tender their shares at an exchange ratio of approximately 2.90, although
they made no commitment to do so.  Based on these circumstances, Vishay
determined to increase the ratio to 2.90.
