Item 2. Acquisition or Disposition of Assets.

      On November 22, 2002, Enzon, Inc., a Delaware corporation ("Enzon"),
completed the acquisition of the North American rights to
ABELCET(R)(Amphotericin B Lipid Complex Injection) from Elan Corporation, plc, a
public limited company organized under the laws of Ireland, Elan
Pharmaceuticals, Inc., a Delaware corporation, Elan Operations, Inc., a Delaware
corporation, and Elan Canada, Inc., a Canadian corporation (Elan
Pharmaceuticals, plc., Elan Pharmaceuticals, Inc., Elan Operations, Inc. and
Elan Canada, Inc. are collectively referred to as "Elan"). ABELCET is an
antifungal used in the hospital to treat patients with invasive fungal
infections related to cancer, organ transplantation and other conditions. Enzon
paid to Elan a cash payment from working capital of $360 million, representing
the final purchase price, which was determined through arms-length negotiations.

      The purchase includes the operating assets associated with the
development, manufacture, sales and marketing of ABELCET in North America,
including a 56,000 square foot manufacturing facility in Indianapolis, Indiana.
Enzon intends to continue to operate these assets for the development,
manufacture, sales and marketing of ABELCET. Additionally, Enzon has hired
certain Elan sales and plant personnel as part of the acquisition.





      The two companies have also agreed that for a maximum period of one year
and at the option of Enzon, Elan will continue to market ABELCET in Canada and
Elan will pay Enzon a royalty. The two companies have also entered into
long-term Manufacturing and Supply Agreements, whereby Enzon will continue to
manufacture products for Elan, including ABELCET, and Elan will retain the
rights to market ABELCET in any markets outside the United States, Canada, and
Japan. As part of the sale, Elan has committed to transfer to Enzon its Japanese
rights to Abelcet, to the extent they exist and are transferable to Enzon.

      The Asset Purchase Agreement by and among Enzon and Elan, which was
previously filed as Exhibit 2.1 to Enzon's Current Report on Form 8-K filed with
the Commission on October 2, 2002, is incorporated herein by reference. The
information contained in Enzon's press release dated November 22, 2002
