Mylan Laboratories Commences Tender Offer

Mylan Laboratories Commences Tender OfferPITTSBURGH, Pa., June 16 /PRNewswire-FirstCall/ -- Mylan Laboratories Inc. (NYSE: MYL) today announced the commencement of its modified "Dutch Auction" self-tender offer for up to approximately 48.8 million shares (up to $1 billion) of its common stock. The tender offer will expire at 5:00 p.m., New York City time, on Friday, July 15, 2005, unless extended.

In the tender offer, shareholders will have the opportunity to tender some or all of their shares at a price not less than $18.00 per share or more than $20.50 per share. Based on the number of shares tendered and the prices specified by the tendering shareholders, Mylan will determine the lowest per share price within the range that will enable it to buy up to approximately 48.8 million shares, or such lesser number of shares as are properly tendered. If more than approximately 48.8 million shares are properly tendered at or below the determined price per share, Mylan will purchase shares tendered by such shareholders, at the determined price per share, on a pro rata basis, as is specified in the offer to purchase relating to the tender offer that will be distributed to shareholders. Additionally, in the event the final purchase price is less than the maximum price of $20.50 per share and more than approximately 48.8 million shares are tendered, Mylan intends to exercise its right to purchase up to an additional 2% of its outstanding common stock without extending the tender offer, so that the Company can repurchase up to $1 billion of its common stock. The tender offer will not be contingent upon any minimum number of shares being tendered. The tender offer will be subject to a number of other terms and conditions, as specified in the offer to purchase.
