The parties currently anticipate that the merger will be completed in the first calendar quarter of 2005.

Dr. Zandman, Chairman and Chief Executive Officer of Vishay stated, “Our acquisition of SI Technologies is another step in Vishay’s strategy to broaden the product offerings of the Vishay Measurements Group. This transaction will further reinforce our position in the transducer, instrumentation and systems markets and will complement and enhance our existing capabilities in these areas.
