Extreme Networks Announces Tender Offer To Repurchase $100 Million of Stock

SANTA CLARA, Calif.; August 11, 2008 – Extreme Networks, Inc. (Nasdaq: EXTR) today announced its intention to commence a “modified Dutch auction” tender offer to purchase $100 million worth of its common stock at a price per share not less than $3.30 and not greater than $3.70. Extreme Networks® intends to commence the stock tender offer today, August 11, 2008, and expects the stock tender offer to expire at 5:00 p.m. New York time on September 12, 2008, unless extended. The maximum number of shares proposed to be purchased in the stock tender offer represents approximately 26% percent of Extreme Networks’ currently outstanding common stock. Extreme Networks will fund the offer from available cash on hand.

Goldman, Sachs & Co. will serve as dealer manager for the stock tender offer. MacKenzie Partners, Inc. will serve as information agent and Mellon Investor Services LLC will serve as the depositary.

Gordon Stitt, Chairman of the Board of Directors, commented: “The Board believes that this offer is an opportunity to increase the long-term value of our stock for our stockholders, while at the same time providing stockholders who wish to tender some or all of their shares a way to do so efficiently.”

A “modified Dutch auction” allows stockholders to indicate how many shares and at what price within Extreme Networks’ specified range they wish to tender. Based on the number of shares tendered and the price specified by the tendering stockholders, Extreme Networks will determine the lowest price per share within the range that will enable it to purchase $100 million worth of its shares, or such lesser dollar value of shares as are properly tendered. At the minimum price of $3.30 per share, Extreme Networks would purchase a maximum of 30,303,030 shares, while at the maximum price of $3.70 per share, Extreme Networks would purchase a maximum of 27,027,027 shares. Extreme Networks will not purchase shares below a price stipulated by a stockholder, and in some cases, may actually purchase shares at prices above a stockholder’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 stockholders of record as of August 7, 2008 beginning on August 11, 2008.

Neither Extreme Networks’ management nor any of its members of the Board of Directors, executive officers, the dealer manager, 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. Stockholders should consult their financial and tax advisors in making this decision.
