PITTSBURGH, Feb 25, 2005 /PRNewswire-FirstCall via COMTEX/ -- Mylan Laboratories Inc. (NYSE: MYL) announced today that a federal district court judge, after hearing all parties, rejected Carl Icahn's application for a temporary restraining order. Mr. Icahn, acting through one of his controlled entities, sought to block enforcement of a recently enacted Mylan advance notice by-law. Under the terms of the by-law, Mr. Icahn is required to furnish the Company with certain information about his nominees by February 28, 2005.

In his lawsuit, Mr. Icahn also is seeking to require Mylan to hold its 2005 Annual Meeting of Shareholders in July. Last week, Mylan's Board scheduled the Annual Meeting to be held on October 28, 2005.
