Novartis Extends Tender Offer for Eon Labs, Inc. Through July 13, 2005


BASEL, Switzerland, July 5, 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:ELABS) from the prior expiration date of 5:30 p.m. New York City time on July 1, 2005, to 5:30 p.m. New York City time on July 13, 2005, since the conditions required to complete the offer have not yet been met.

Accordingly, the tender offer and withdrawal rights will expire at 5:30 p.m. New York City time on July 13, 2005. However, if shares are not accepted for payment by July 21, 2005, Eon Labs 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Based on a preliminary count by the depositary for the offer, there were tendered and not withdrawn 18,879,261 shares of Eon Labs common stock as of 5:30 p.m. New York City time on July 1, 2005, and an additional 884,776 shares were guaranteed to be delivered within the next three days. These shares represent approximately 22.24 percent of the total outstanding shares of Eon Labs, and approximately 68.43 percent of the total outstanding shares of Eon Labs, excluding those shares owned by Santo Holding (Deutschland) GmbH, Eon's majority shareholder.

The completion of the tender offer and the purchase by Novartis of the 67.7 percent stake in Eon Labs from Santo 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.
