("ZODNAS"), a Delaware corporation and an indirect wholly owned subsidiary of Novartis US. The Schedule TO relates to the offer by Zodnas to purchase any and all of the outstanding shares of common stock, par value $0.01 per share (the "SHARES"), of Eon Labs, Inc., a Delaware corporation ("EON"), for $31.00 per Share, net to the seller in cash, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated May 23, 2005 (the "OFFER TO PURCHASE"), and in the related Letter of Transmittal. Copies of the Offer to Purchase and the related Letter of Transmittal are filed with the Schedule TO as exhibits (a)(1)(A) and (a)(1)(B), respectively. Capitalized terms used and not defined herein shall have the meanings assigned such terms in the Offer to Purchase and Schedule TO. ITEMS 1 THROUGH 9 AND 11. Items 1 through 9 and 11 of the Schedule TO, which incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented as follows: On July 8, 2005, the Offer was extended through 5:30 pm New York City time, on July 20, 2005. Accordingly, the term "Expiration Date" means 5:30 pm New York City time on July 20, 2005, unless we further extend the period of time during which the Offer will be open, in which case the term "Expiration Date" will mean the date at which the Offer, as so extended, will expire. SETTLEMENT MEMORANDUM. On July 8, 2005, the defendants in the Delaware litigation relating to the Offer and the Merger in the pending suit styled IN RE EON LABS, INC. SHAREHOLDERS LITIGATION (including Eon Labs, the members of its Board of Directors and Novartis), entered into a memorandum of understanding (the "Settlement Memorandum") with the plaintiffs in the litigation, pursuant to which the parties agreed to a settlement of the litigation. Pursuant to the Settlement Memorandum, EON Labs has made certain additional disclosures in its Recommendation Statement on Schedule 14D-9 and Novartis agreed to extend the tender offer until at least July 15, 2005. In addition, among other things, the Settlement Memorandum amends the relevant provisions of Merger Agreement and Confidentiality Agreement to provide that if, upon consummation of the Offer, less than a majority of the Public Shares are tendered in the Offer, prior to August 11, 2006, Novartis will not be able to cause a merger transaction (or other business combination) to be effected that would cancel Public Shares unless (i) a majority of the outstanding Public Shares outstanding at that time votes in favor of such a transaction and the Company shall have received an opinion of an independent, nationally recognized investment banking firm that the consideration offered in such transaction is fair to the holders of the Public Shares from a financial point of view, or (ii) Novartis and its subsidiaries, at that time, own at least 90% of the outstanding Company Common Stock; PROVIDED, that the consideration to be received by the holders of Public Shares in any such transaction described in (i) or (ii) above must be at least equal to the Offer Price. Pursuant to the Settlement Memorandum, Novartis and Merger Sub also agreed to use commercially reasonable efforts, following the date on which Merger Sub is obligated to accept for payment any and all Public Shares tendered and not validly withdrawn pursuant to the Offer and until the earlier of (i) effective time of the Merger and (ii) August 11, 2006, to keep the Eon Labs Common Stock quoted for trading on the NASDAQ National Market, so long as Eon Labs satisfies the NASDAQ National Market listing standards (other than standards entirely within its control). Novartis and Merger Sub remain free to make acquisitions of Public Shares that are voluntary to the holders of Public Shares, but Novartis and Merger Sub will take into account the potential for such acquisitions to result in Eon Labs' inability to satisfy NASDAQ National Market listing standards. The settlement outlined in the Settlement Memorandum is subject to, among other things (i) execution of definitive settlement documentation (ii) final court approval of the settlement (iii) dismissal of the litigation with prejudice and without awarding costs to any party (except as contemplated by the Settlement Memorandum), and (iv) Novartis's acceptance of the tendered shares for payment under the Offer. In the event that the settlement is consummated, plaintiffs in the Delaware litigation will release on behalf of themselves and a class of Eon shareholders all claims that they have or could have asserted against the defendants and certain related parties arising out of, among other things, the Merger Agreement, the Santo Agreement or the Hexal Agreement. The full text of the press release announcing the extension of the Offer as described above is attached as Exhibit (a)(5)(G) hereto and is incorporated herein by reference. The Settlement Memorandum is attached as Exhibit (a)(6)(J) hereto and is incorporated herein by reference. ITEM 12.
