ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On June 3, 2004, pursuant to the Agreement and Plan of Merger, dated April
15, 2004 (the "Merger Agreement"), by and among The Lubrizol Corporation
("Lubrizol"), Lubrizol Acquisition Corporation and Noveon International, Inc.
("Noveon International"), Lubrizol Acquisition Corporation was merged with and
into Noveon International. In connection with the merger, Noveon International
was the surviving corporation and became a wholly owned subsidiary of Lubrizol.

     Noveon International is a global producer and marketer of technologically
advanced specialty chemicals for a broad range of consumer and industrial
applications. Lubrizol intends to utilize the assets of Noveon International and
its subsidiaries to produce substantially the same specialty chemicals sold by
the acquired businesses prior to the merger.

     Lubrizol paid approximately $920.0 million for the equity of Noveon
International, minus certain transaction expenses of Noveon International, and
expects to pay an aggregate of approximately $1.1 billion in connection with the
refinancing of the outstanding indebtedness of Noveon International and its
subsidiaries. The amount of consideration paid for the equity of Noveon
International was determined through arms-length negotiations between Lubrizol
and Noveon International.

     Lubrizol financed the acquisition of Noveon International, and will be
refinancing the indebtedness of Noveon International and its subsidiaries,
through draws under Lubrizol's 364-Day Credit Agreement, dated May 28, 2004 (the
"364-Day Credit Agreement"), entered into with Citicorp North America, Inc.,
KeyBank National Association, ABN AMRO Bank N.V., Wachovia Capital Investments,
Inc., The Bank of Tokyo-Mitsubishi, Ltd. and PNC Bank, National Association.

     Prior to the merger, Noveon International was controlled by AEA Investors
LLC, Credit Suisse First Boston LLC, MidOcean Capital/PMD Investors, LLC and
their respective affiliates.

     Copies of the Merger Agreement, certain ancillary agreements, the 364-Day
Credit Agreement and the press release announcing the completion of the merger
