Tokyo, Japan, September 25, 2012 - Tokyo Electron Limited ("Tokyo Electron"; Headquarters: Tokyo; President and CEO: Hiroshi Takenaka) (TSE: 8035) announced today that Tokyo Electron's wholly-owned subsidiary, RB Merger Corp., has extended the expiration date of its tender offer for all outstanding shares of common stock of FSI International, Inc. ("FSI"; Headquarters: Chaska, Minnesota, USA; Chairman and CEO: Donald Mitchell) (NASDAQ: FSII) for $6.20 in cash for each share of FSI common stock validly tendered and not validly withdrawn in the offer, without interest and less any applicable withholding taxes. The tender offer is now scheduled to expire at 12:00 midnight (New York City time) on Wednesday, October 10, 2012, unless further extended. The tender offer was previously scheduled to expire at 12:00 midnight (New York City time) on Monday, September 24, 2012.
