John Villas To Retire As Entegris CFO In Early 2007; Gregory Graves To Be Named To Post

Gregory B. Graves, senior vice president of strategic planning and business development for Entegris, will be named to the post of CFO at that time, in addition to his current responsibilities.



"We thank John for his tremendous dedication, financial leadership, and for his many important contributions to Entegris over the years, and we wish him the very best in the future," said Gideon Argov, president and chief executive officer of Entegris. "We are fortunate to have someone of Greg's caliber on the management team to fill John's role. Greg's background makes him very well suited to be CFO and the handoff should be a smooth one as he and John work together closely over the next several months to make the transition."



Villas joined Entegris in 1984, and fulfilled several key financial positions including controller, corporate controller and financial vice president. As CFO, he had a key role in bringing the company public in 2000 and in the merger between Entegris and Mykrolis in 2005.



"For some time I have considered how I might be able to spend more time with my family and eventually pursue other opportunities," said Villas. "With the merger integration completed, I feel the time is right for me personally and for the company to leave Entegris. It has been an honor and a pleasure to have served as the CFO at Entegris. I am convinced that the vision of Entegris will lead to greater solutions for our customers and stronger results for our shareholders. The financial management will be in excellent hands with Greg."

Graves has served as Entegris' chief business development officer responsible for strategic planning since joining the company in September 2002. He previously served in investment banking and corporate development positions with Piper Jaffray, RBC Capital Markets (formerly Dain Rauscher), and The Pillsbury Company, and worked as a certified public accountant with Deloitte & Touche. Graves earned his BS and Masters in Accounting at the University of Alabama, and his MBA from the Darden School at the University of Virginia.
