Entegris, Inc. Announces Tender Offer To Repurchase $250 Million of Stock

The Company intends to commence the stock tender offer tomorrow, May 11, 2007, and expects the stock tender offer to expire at 11:59 p.m. on June 8, 2007, unless extended. The number of shares proposed to be purchased in the stock tender offer represents approximately 15% percent of the Company's currently outstanding common stock.



The Company will finance the offer with $175 million from available cash on hand together with the proceeds from a $75 million bridge loan facility. The company intends to refinance the bridge loan facility with debt securities, convertible debt securities or a bank loan.



"The magnitude and nature of this share repurchase, which follows a $100 million buyback we completed in October 2006, reflects our confidence in Entegris' future," said Gideon Argov, chief executive officer. "We believe that this recapitalization will result in a capital structure that can leverage our business model and will allow us to use our strong financial position and cash flow to build long-term shareholder value."



Goldman, Sachs & Co., and Citigroup Global Markets Inc. will serve as dealer managers for the stock tender offer. MacKenzie Partners, Inc. will serve as information agent and Wells Fargo Bank, N.A. will serve as the depositary.



A modified "Dutch auction" allows shareholders to indicate how many shares and at what price within the Company's specified range they wish to tender. Based on the number of shares tendered and the price specified by the tendering shareholders, the Company will determine the lowest price per share within the range that will enable it to purchase up to 20.4 million company shares, or such lesser number of shares as are properly tendered. The Company will not purchase shares below a price stipulated by a shareholder, and in some cases, may actually purchase shares at prices above a shareholder's indication under the terms of the modified "Dutch auction." The stock tender offer is not contingent upon a minimum number of shares being tendered but is conditioned on a number of events as described in the offer to purchase. Specific instructions and a complete explanation of the terms and conditions of the stock tender offer are contained in the Offer to Purchase and related materials that will be mailed to shareholders of record beginning on May 11, 2007.



None of Entegris' management, its board of directors, the dealer managers, the information agent or the depositary is making any recommendation to stockholders as to whether to tender or refrain from tendering their shares in the stock tender offer. Stockholders must decide how many shares they will tender, if any, and the price within the stated range at which they will tender their shares. Shareholders should consult their financial and tax advisors in making this decision.



In August 2006 the Company had announced a $150 million share repurchase authorization, of which approximately $100 million was executed in September and October of 2006 in the form of an accelerated stock buyback program. The Company expects approximately $50 million of the August 2006 authorization to remain following the completion of the stock tender offer.
