Item 5. Other Events.

On October 1, 2002, Enzon, Inc., a Delaware corporation ("Enzon"), and 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
(collectively, "Elan"), entered into an Asset Purchase Agreement (the "Asset
Purchase Agreement"), pursuant to which, and subject to the terms and conditions
of which, Enzon has agreed to acquire the United States and Canadian rights to
ABELCET(R) (Amphotericin B Lipid Complex Injection),an FDA-approved, injectable,
antifungal pharmaceutical product, along with any line extensions, new
indications, new formulations and new dosage forms of ABELCET, for an aggregate
purchase price of $370 million, subject to certain adjustments described in the
Asset Purchase Agreement. In addition, the Asset Purchase Agreement contemplates
the acquisition of the manufacturing facility for ABELCET in Indianapolis,
Indiana, marketing materials, finished inventory and raw materials and certain
contracts related to ABELCET and the manufacturing facility. Elan will retain
rights to ABELCET outside of Canada and the United States, except to the extent
Elan has rights in Japan which will also be conveyed to Enzon.

In connection with the transactions, Enzon expects to hire a hospital sales
force of approximately 60 Elan employees who currently market and sell ABELCET
in the United States and Canada, as well as the manufacturing facility
personnel.


Elan and Enzon have also agreed to enter into a patent assignment agreement, a
license agreement, trademark assignment agreements, two supply agreements, and
an interim services agreement, among other documents, in order to implement the
terms of the transactions. Elan and Enzon have agreed to the assignment of
certain patent rights and improvements specifically related to ABELCET, as well
as an exclusive license as to certain patent rights, improvements and related
intellectual property for ABELCET. With respect to the intellectual property
assigned to Enzon, the license agreement will include a grant by Enzon to Elan
of an exclusive license (i) inside the United States and Canada for certain
technologies outside the scope of ABELCET, and (ii) outside the United States
and Canada for all technologies.

The transactions are expected to close during the fourth calendar quarter of
2002, subject to certain closing conditions, including, among others, the
approval of Elan's shareholders, the delivery to Enzon of required audited
financial statements relating to ABELCET, the receipt of certain third-party
consents, the receipt of required regulatory approvals and clearances, including
termination of the applicable waiting period under the Hart-Scott-Rodino Act,
approvals of the UK Listing Authority and Dublin Stock Exchange and clearance
under the Ireland Mergers and Takeovers (Control) Acts 1978-1996, and other
customary closing conditions.
