ICAHN /s/ Gail Golden GAIL GOLDEN [Signature Page of Amendment No. 8 to Schedule 13D with respect to Mylan] Exhibit 1 FOR IMMEDIATE RELEASE ICAHN UNIT COMMENTS ON MYLAN New York, New York, July 18, 2005 Contact: Susan Gordon (212) 702-4309 On July 26, 2004, Mylan announced its intention to acquire King Pharmaceuticals. Thereafter, Mylan stock traded as low as $14.69 per share. Following that announcement, Mr. Icahn became involved in Mylan as a shareholder activist and, among other things, strongly criticized the proposed King acquisition as "reprehensible" and not in the best interest of Mylan shareholders. Mr. Icahn also announced his intention to conduct a proxy fight at Mylan. Since Icahn's involvement as a shareholder activist and vocal critic of the Mylan Board and management, Mylan has: (i) abandoned the King transaction; (ii) announced the $1.25 billion share buy-back; (iii) doubled its dividend rate; (iv) taken steps to exploit Nebivolol through a major distribution partner and (v) announced the retirement of two of its non-independent directors. On July 15, 2005, the expiration date of the Mylan tender offer, Mylan's stock closed at $19.40, an increase of 32% from the time of Mr. Icahn's involvement. Mr. Icahn stated: "There is no question that shareholder activism has worked well to enhance shareholder value at Mylan." Icahn affiliate High River Limited Partnership tendered 26,291,200 shares of Mylan common stock pursuant to the Mylan tender offer. The determination to tender was made late on July 15, following the announcement by the FDA regarding Mylan's generic Duragesic product, with no clarification or further comment from Mylan. High River's determination to tender was based on careful consideration of the above factor, and, among other things, its belief that it would be difficult to win a proxy fight with the stock trading at the current levels. As previously stated, Mr. Icahn did not wish to be a passive investor in this company. Mr. Icahn is still of the belief that shareholder value will be further enhanced if Mylan were put up for sale and consolidated with a larger company. At this time, the determination whether or not Icahn will conduct a proxy fight at Mylan will be dependent, for the most part, on the price at which Mylan's stock trades over the next several weeks, the actions of management and the views of large Mylan shareholders.
