Lundbeck A/S ("Lundbeck"), Viking Sub Corporation and Synaptic Pharmaceutical Corporation ("Synaptic"), Lundbeck entered into a Stockholder Agreement dated as of November 21, 2002 (the "Stockholder Agreement"), with Warburg Pincus Private Equity VIII, L.P. ("Warburg Pincus"). Under the terms of the Stockholder Agreement, Warburg Pincus has agreed to vote all of its 9,398 shares of Synaptic Series B Convertible Preferred Stock (the "Series B Preferred Stock") and 25,452 shares of Synaptic Series C Convertible Preferred Stock (the "Series C Preferred Stock" and, together with the Series B Preferred Stock, the "Synaptic Preferred Stock") in favor of the Merger Agreement and against any competing transactions. In addition, Warburg Pincus has granted Lundbeck an irrevocable proxy to vote the Synaptic Preferred Stock in accordance with the Stockholder Agreement. The Stockholder Agreement terminates upon the earlier of (i) the effective time of the merger contemplated by the Merger Agreement and (ii) the termination of the Merger Agreement in accordance with its terms. The Stockholder Agreement is filed as Exhibit 1 to the Schedule 13D/A filed pursuant to the Securities Exchange Act of 1934, as amended (the "Securities Exchange Act"), by Warburg Pincus on November 22, 2002 (file no. 005-45417), and is incorporated herein by reference. The Merger Agreement is filed as Exhibit 2.1 to the Form 8-K filed by Synaptic pursuant to the Securities Exchange Act on November 21, 2002 (file no. 000-27324), and is incorporated herein by reference. Because the Synaptic Preferred Stock is convertible into 6,429,923 shares of common stock, par value $.01 per share (NASDAQ: SNAP) (the "Common Stock"), for purposes of calculating ten percent beneficial ownership, Lundbeck is deemed to "beneficially own" (as defined in Rule 16a-1(a)(1) promulgated under the Securities Exchange Act) 6,429,923 shares of Common Stock, 9,398 shares of Series B Preferred Stock and 25,452 shares of Series C Preferred Stock. However, for purposes of disclosing securities holdings on this Form 3, Lundbeck does not "beneficially own" (as defined in Rule 16a-1(a)(2) promulgated under the Securities Exchange Act) any equity security of Synaptic. (2) The Synaptic Preferred Stock is subject to mandatory redemption as follows: (i) on August 3, 2009, Synaptic shall redeem fifty percent (50%) of Synaptic Preferred Stock outstanding on such date, and (ii) on August 3, 2010, Synaptic shall redeem all shares of Synaptic Preferred Stock which remain outstanding as of such date. (3) The Series B Preferred Stock is convertible into 2,167,535 shares of Common Stock and the Series C Preferred Stock is convertible into 4,262,388 shares of Common Stock. **Intentional misstatements or omissions of facts constitute Federal Criminal Violations.
