Item 8.01. Other Events.

On August 23, 2006, ADE Corporation extended from August 28, 2006 to November 10, 2006 the “end date” under the Amended and Restated Merger Agreement between KLA-Tencor and ADE. Unless the merger has been completed by such date or such date is further extended by mutual agreement of KLA-Tencor and ADE, either party may thereafter terminate the Merger Agreement. ADE extended this date to allow KLA-Tencor additional time to obtain regulatory clearance from German antitrust authorities, who as previously reported, notified KLA-Tencor on Monday, July 10, 2006 of the commencement of a Phase II investigation of the proposed merger.

A closing date will be established once the parties have cleared or waived all conditions to close, including regulatory clearance from the German antitrust authorities. Both ADE and KLA-Tencor continue to be confident that the merger will be completed once German antitrust clearance is obtained.

This Current Report on Form 8-K contains certain forward-looking statements within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995 and federal securities law. Such forward-looking statements are subject to known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements.

Further information on potential factors that could affect KLA-Tencor’s or ADE’s respective businesses is contained in their reports on file with the Securities and Exchange Commission, including their respective Form 10-K’s. KLA-Tencor and ADE are under no obligation to (and expressly disclaim any such obligation to) update or alter their respective forward-looking statements whether as a result of new information, future events or otherwise.
