On March 28, 2011, Verigy Ltd. entered into an Implementation Agreement with Advantest Corporation pursuant to which Advantest proposes to acquire all outstanding Verigy ordinary shares (other than those held by Advantest and its subsidiaries) for $15 per share (the “Transaction”). As Verigy previously announced, on June 9, 2011, Verigy received notification from the United States Department of Justice, Antitrust Division, of the termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. In addition, Verigy announced on June 10, 2011 that the waiting period for regulatory review in Taiwan has expired. The obligation of Advantest to consummate the Transaction is conditioned on the expiration of these regulatory review periods, among other conditions.

A copy of the press release issued by Verigy on June 10, 2011 is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
