Novartis Extends Tender Offer for Eon Labs, Inc. Through July 1, 2005


BASEL, Switzerland, June 21, 2005 (PRIMEZONE) -- Novartis announced today that Zodnas Acquisition Corp., an indirect wholly owned subsidiary of Novartis, is extending its cash tender offer to acquire all outstanding public shares of Eon Labs, Inc. (Nasdaq:ELAB) from the prior expiration date of 12:00 midnight New York City time on June 20, 2005 to 5:30 p.m. New York City time on July 1, 2005.

Accordingly, the tender offer and withdrawal rights will expire at 5:30 p.m. New York City time on July 1, 2005. However, if shares are not accepted for payment by July 21, 2005, Eon shareholders will be able to withdraw their tendered shares at any time after July 21, 2005 and before their shares are accepted for payment.

Based on a preliminary count by the depositary for the offer, there were tendered and not withdrawn 22,152,720 shares of Eon Labs common stock as of 12:00 midnight on June 20, 2005 and an additional 2,297,759 shares are guaranteed to be delivered within the next three days.

The completion of the tender offer and the purchase by Novartis of the 67.7 percent stake in Eon Labs from Santo Holding (Deutschland) GmbH, Eon's majority shareholder, are subject to the receipt of U.S. regulatory approval. Novartis will purchase Santo's shares immediately following completion of the tender offer.

A hearing on plaintiff's motion for a preliminary injunction in In re Eon Labs, Inc. Shareholders Litigation is currently scheduled for July 8, 2005 in the Delaware Chancery Court in the U.S. Novartis does not currently expect to receive regulatory approval prior to the court's hearing. However, Novartis, Eon and Santo have agreed that Novartis will not complete the tender offer or the purchase of Santo's shares while the motion for preliminary injunction is pending.
