Item 8.01. Other Events.

On June 7, 2006, Dean Drulias, a purported shareholder of ADE Corporation, or ADE, filed a complaint in Massachusetts Superior Court, Norfolk County, against ADE, each of ADE’s directors, KLA-Tencor Corporation, or KLA-Tencor, and South Acquisition Corporation, or South, entitled Dean Drulias v. ADE Corporation, et al. (Civil Action No. 06-00963). The complaint alleges, among other things, that in connection with the sale of ADE to KLA-Tencor, or the Merger, the directors of ADE breached their fiduciary duties, ADE’s preliminary proxy statement related to the Merger contains inaccurate statements of material facts and omits material facts and KLA-Tencor has aided and abetted ADE’s directors in their alleged breaches of fiduciary duties. Among other things, the complaint seeks a determination that the class action status is proper, an enjoinment of the Merger, or if the Merger is consummated, rescission of the Merger, and the payment of compensatory damages and other fees and costs. Although the ultimate outcome of this matter cannot be determined with certainty, ADE believes that the complaint is completely without merit and it and the other defendants intend to vigorously defend this lawsuit.
