SECURITY AND ISSUER This Schedule 13D filed by Novartis AG ("Novartis"), Novartis Corporation, ("Novartis Corp"), and Zodnas Acquisition Corp. ("Zodnas" and, together with Novartis and Novartis Corp, the "Reporting Persons") relates to the Common Stock, par value $0.01 per share (the "Common Stock"), of Eon Labs, Inc., a Delaware corporation (the "Company"). The principal executive offices of the Company are located at 1999 Marcus Avenue, Lake Success, NY 11042. ITEM 2. IDENTITY AND BACKGROUND (a), (b), (c) and (f). The name, business address, present principal occupation or employment and citizenship of the executive officers and members of the Board of Directors of each of the Reporting Persons is set forth on Schedule I hereto and is incorporated herein by reference. (d) and (e). None of the Reporting Persons nor, to the best knowledge of each of them, any of the persons listed on Schedule I hereto with respect to each such Reporting Person during the last five years, (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION The funds for the transactions described in Item 4 below will be obtained from cash on hand. ITEM 4. PURPOSE OF TRANSACTION (a) and (b). On February 20, 2005, Novartis Corp, Santo Holding (Deutschland) GmbH ("Santo") and for purposes of Section 12 thereof only, Novartis, entered into an Agreement for Purchase and Sale of Stock (the "Santo Stock Purchase Agreement") relating to the purchase by Novartis Corp (or its designee) of 60,000,000 shares of Common Stock (the "Santo Shares") representing approximately 67.5% of the outstanding shares of Common Stock. A copy of the Santo Stock Purchase Agreement is attached as Exhibit 2.1 hereto and incorporated by reference herein. Also on February 20, 2005, Novartis Corp, Zodnas, the Company and for purposes of Section 10.12 only, Novartis, entered into an Agreement and Plan of Merger (the "Merger Agreement"). The Merger Agreement provides for Zodnas to commence a tender offer (the "Offer") for any and all shares of the Common Stock at a price of $31.00 per share in cash (the "Offer Price"). However, although the Offer is being made for any and all shares of Common Stock, Santo has agreed to sell the Santo Shares to Novartis Corp (or its designee) pursuant to the Santo Stock Purchase Agreement at a price per share that is less than the Offer Price. Therefore, effectively the Offer will be made for all shares of Common Stock, other than the Santo Shares (the "Public Shares"). The closing of the Offer is conditioned, among other things, upon the contemporaneous or immediately subsequent purchase of the Santo Shares under the Santo Stock Purchase Agreement. The Merger Agreement further provides that if a majority of the Public Shares are tendered into the Offer, Novartis Corp will cause a merger of Zodnas with and into the Company, with the Company surviving, where all of the remaining holders of Common Stock will receive $31.00 per share (the "Merger"). In the event that less than a majority of the Public Shares are tendered into the Offer, the Merger Agreement provides that the standstill provisions in the Confidentiality Agreement, dated as of February 11, 2005 by and between Novartis Corp and the Company (the "Confidentiality Agreement") will be amended to provide that Novartis Corp and Zodnas will be permitted to make acquisitions of shares of Common Stock that are voluntary to the holders of Common Stock (such as by means of legally permissible open market purchases or additional tender offers) and may consummate a merger or other business combination with the Company prior to February 11, 2006, only if: (1) a majority of the then- 9 outstanding Public Shares approve such transaction; or (2) Novartis Corp and its subsidiaries own 90% or more the total outstanding shares of Company Stock, provided that the price per share of Common Stock paid in any such transaction described in (2) above is at least equal to the Offer Price. Following the completion of the Offer, Novartis Corp and Zodnas are required to use their reasonable best efforts to keep the Common Stock quoted for trading on the NASDAQ National Market as long as the Company is registered under the Securities Exchange Act of 1934, as amended and satisfies the NASDAQ National Market's listing standards (other than standards entirely within the Company's control). Further, the Merger Agreement provides that from and after the date on which Zodnas becomes obligated to accept for payment any and all shares of Common Stock tendered into the Offer, Novartis Corp will be entitled to designate each member of the Company's Board of Directors, and the Company will be required to promptly take all actions necessary to cause Novartis Corp's designees to be so elected. However, if Novartis and Zodnas have purchased in the Offer a majority of the Public Shares, then until the effective time of the Merger, Novartis Corp and Merger Sub will permit the members of the special committee (the "Special Committee") of the Company's Board of Directors (or their designees) to remain on the Company's Board of Directors. A copy of the Merger Agreement is attached hereto as Exhibit 2.2 and incorporated by reference herein and a copy of the Confidentiality Agreement is attached as Exhibit 2.3 hereto and incorporated by reference herein. The summaries of each of the Santo Stock Purchase Agreement, the Merger Agreement and the Confidentiality Agreement are qualified in their entireties by reference to the full text of the documents attached hereto as Exhibits 2.1, 2.2 and 2.3, respectively. A copy of the press release relating to the transactions described above is attached as Exhibit 99.1 hereto and incorporated by reference herein. ITEM 5. INTEREST IN SECURITIES OF ISSUER (a) and (b) On February 16 and 17, 2005, Novartis (Deutschland) GmbH ("Novartis Deutschland") and Novartis (as guarantor) entered into a Share and Partnership Interest Sale and Transfer Agreement (the "Hexal Agreement"), with Dr. Andreas Strungmann, Ms. Susan Strungmann, Ms. Nicole Strungmann, Mr. Florian Strungmann, Dr. Thomas Strungmann, Ms. Cornelia Strungmann, Mr. Fabian Strungmann, Ms. Janina Strungmann, Ms. Fiona Strungmann, Mr. Felix Strungmann, Hexal Aktiengesellschaft and A+T Vermogensverwaltung GmbH, relating to the acquisition of shares in A+T Vermogensverwaltung GmbH as well as partnership interests in A+T Holding GmbH & Co. KG (the "Hexal Business"). In connection with the purchase of the Hexal Business, Novartis Deutschland will acquire 132,122 shares of Common Stock currently held by the companies comprising the Hexal Business (the "Hexal Owned Shares"), which represents approximately .1% of the outstanding shares of Common Stock. Other than as described in this Item 5 and in Item 4 above, as of the date hereof, none of the Reporting Persons are the record holder of any shares of Common Stock or have the right to acquire any Common Stock. Novartis Corp may be deemed to have shared power to dispose or to direct the disposition with respect to the Santo Shares and Novartis may be deemed to have shared power to dispose or to direct the disposition with respect to the Hexal Owned Shares. Novartis is the beneficial owner of all Common Stock beneficially owned by Novartis Corp and Novartis Deutschland. The Reporting Persons hereby disclaim beneficial ownership of any shares of Common Stock. To the best knowledge of each of the Reporting Persons, none of the persons listed on Schedule I hereto with respect to such Reporting Person is the beneficial owner of any shares of Common Stock. 10 (c) Neither the Reporting Persons nor, to the best knowledge of each of the Reporting Persons, any of the persons listed on Schedule I with respect to each such Reporting Person has engaged in any transaction in the Common Stock in the past 60 days other than as described in Item 4 and Item 5 above.
