Forward Looking Statements

Some statements set forth in this communication, including those regarding Vishay's proposal to acquire International Rectifier and the expected impact of the acquisition on Vishay's strategic and operational plans and financial results, contain forward-looking statements including statements which are, except in connection with Vishay's proposed tender offer to acquire the outstanding shares of International Rectifier, within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. Statements including words such as "intend", "believe", "should", "expect", "are confident" or similar words as well as statements in the future tense are forward-looking statements. The safe harbors intended to be created by Sections 27A and 21E are not available to statements made in connection with a tender offer and Vishay is not aware of any judicial determination as to the applicability of such safe harbors to forward-looking statements made in solicitation materials when there is a simultaneous tender offer. Stockholders should be aware that these forward-looking statements are subject to risks and uncertainties that could cause actual events or actual future results to differ materially from the expectations set forth in the forward-looking statements. Some of the factors which could cause results to differ materially from the expectations expressed in these forward-looking statements include the following: the possibility that Vishay's offer to acquire International Rectifier will not be consummated for any number of reasons, including the failure of the stockholders of International Rectifier to support the proposed transaction, the failure of any conditions to Vishay's tender offer to be satisfied, or the failure to obtain financing on terms acceptable to Vishay; the possibility that if approved, the closing of the acquisition may be delayed; the effect of the announcement of the offer on Vishay's and International Rectifier's strategic relationships, operating results and business generally, including the ability to retain key employees; fees and expenses incurred in connection with Vishay's unsolicited acquisition proposal, director nominations and stockholder proposals; Vishay's ability to successfully integrate International Rectifier's operations and employees and achieve synergies; the risk that Vishay's acquisition proposal will make it more difficult for Vishay to pursue other strategic opportunities; the risk that stockholder litigation in connection with Vishay's unsolicited proposal, or otherwise, may result in significant costs of defense, indemnification and liability; general economic conditions; and other factors described in Vishay's SEC filings (including Vishay's Annual Report on Form 10-K for the year ended December 31, 2007 and Quarterly Reports on Form 10-Q for the quarters ended March 29, 2008 and June 28, 2008). If any of these risks or uncertainties materializes, the acquisition may not be consummated, the potential benefits of the acquisition may not be realized, Vishay's and/or International Rectifier's operating results and financial performance could suffer, and actual results could differ materially from the expectations described in these forward-looking statements. All forward-looking statements in this news release are qualified by these cautionary statements and are made only as of the date of this news release. Vishay undertakes no duty to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise.
