Acquisition or Disposition of Assets. On November 6, 2001, Immunex Corporation, a Washington corporation ("Immunex"), entered into a Purchase Agreement with American Home Products Corporation, a Delaware corporation ("AHP") and AHP Subsidiary Holding Corporation, a Delaware corporation and wholly owned subsidiary of AHP ("Holdings"), which provided for Immunex's purchase from Holdings of all of the outstanding shares (the "Shares") of Greenwich Holdings Inc. ("Greenwich"). The Purchase Agreement was described in, and filed as an exhibit to, Immunex's Current Report on Form 8-K filed on November 13, 2001. Greenwich owns the biopharmaceutical manufacturing facility in West Greenwich, Rhode Island, that Immunex and AHP have worked together to retrofit to accommodate the commercial production of ENBREL(R) (etanercept). U.S. Food and Drug Administration ("FDA") approval of the facility is anticipated in the second half of 2002. As part of the definitive Purchase Agreement, Immunex paid $188,965,335 to AHP and Holdings at signing. On December 21, 2001, Immunex, AHP and Holdings entered into Amendment No. 1 to the Purchase Agreement (the "Amendment") to provide for payment of the purchase price for the Shares with a short-term promissory note, the terms of which are described below, instead of in cash. On January 1, 2002, Immunex, AHP and Holdings completed the transactions contemplated by the Purchase Agreement. Immunex became the owner of the Shares and, by extension, all of the assets of Greenwich, including the Rhode Island facility. Immunex plans to continue the operation of the facility as proposed by AHP and Holdings once the facility is approved for production by the FDA. Under the terms of the Purchase Agreement, as amended, Immunex issued a Secured Promissory Note (the "Note") in favor of AHP and Holdings in the amount of $279,417,982 in payment of the balance of the purchase price for the Shares. This amount represents the parties' estimate of the net value of Greenwich's assets as of November 30, 2001, less the amount Immunex paid at signing. The Note becomes due and payable on January 25, 2002 and is secured by the Shares, as provided in a Pledge Agreement, dated January 1, 2002, by and among Immunex, AHP and Holdings. In addition, the Purchase Agreement provides for a post-transaction reconciliation to include an additional payment by Immunex in the amount by which the net value of Greenwich's assets increased between November 30, 2001 and January 1, 2002. This reconciliation amount is expected to be approximately $27 million. AHP and its affiliates and subsidiaries hold an approximate 41% equity interest in Immunex. The above description of Immunex's purchase of the Shares is a summary and as such is not intended to be complete. It is subject to, and qualified by reference to, the Purchase Agreement, which is attached as Exhibit 10.1 to Immunex's Current Report on Form 8-K filed on November 13, 2001, the press release announcing execution of the Purchase Agreement, which is attached as Exhibit 99.1 to Immunex's Current Report on Form 8-K filed on November 2 13, 2001, and the Amendment, the Note and the Pledge Agreement, which are attached as exhibits to this Current Report on Form 8-K.
