Mylan Submits a Supplement to Its Citizens Petition Regarding Authorized Generics to the FDAPITTSBURGH, June 30 /PRNewswire-FirstCall/ -- Mylan Laboratories Inc. (NYSE: MYL) today announced that it has supplemented its citizens petition dated February 17, 2004 asking for an immediate response from the FDA.

Robert J. Coury, Mylan's CEO and Vice Chairman of the Board, stated, "The damage to us through lost market opportunity, as well as to the generic industry and ultimately consumers who rely on generics to contain healthcare cost, makes this an issue that deserves to be addressed. Considerable time has passed since we filed our original petition with the FDA in February. We believe Congressional intent is clear regarding the launch of generics into the marketplace and have therefore requested that the FDA clarify its position."

Mr. Coury went on to say, "Because we anticipate that the courts will ultimately have to resolve this matter, it is imperative that the FDA responds to this important industry issue."

A copy of the original citizens petition dated February 17, 2004 and the supplement submitted to the FDA on June 28, 2004 will be filed with a Form 8-K and will be accessible to the public on the SEC's website at www.sec.gov .

In addition, Mylan's previously announced lawsuit against the FDA seeking to restore final approval for its fentanyl transdermal system will also be filed with an 8-K and be accessible to the public in an 8-k filing today.
