Morgan Stanley Added to Vishay Intertechnology Team for International Rectifier Bid

MALVERN, Pa., Sep 15, 2008 (BUSINESS WIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced that Morgan Stanley & Co. Incorporated is working alongside Bank of America to provide Vishay with financing commitments on mutually acceptable terms and conditions in connection with its proposed acquisition of International Rectifier Corporation (NYSE: IRF).

Vishay also announced that Morgan Stanley will be acting as a financial advisor to Vishay in connection with the proposed transaction, together with Banc of America Securities LLC, lead financial advisor to Vishay.

As previously announced on September 10, 2008, Vishay Corporation increased the price of its all-cash proposal to acquire all of the outstanding shares of International Rectifier common stock to $23.00 per share. The increased proposal represents a premium of 22% to International Rectifier's closing stock price on August 14, 2008, the last trading day prior to public disclosure of Vishay's original acquisition proposal, and a 30% premium over International Rectifier's average closing price for the 30 trading days preceding that announcement. The transaction has a value of approximately $1.7 billion in the aggregate. Vishay intends to commence shortly a tender offer to purchase all of the outstanding shares of International Rectifier common stock for $23.00 per share in cash.

Vishay expects to file a preliminary proxy statement with the Securities and Exchange Commission shortly.

Wachtell, Lipton, Rosen & Katz is acting as legal counsel to Vishay, and Banc of America Securities LLC and Morgan Stanley & Co. Incorporated are acting as financial advisors. Innisfree M&A Incorporated has been retained by Vishay as Information Agent and proxy solicitor.
