ITEM 2.      ACQUISITION OR DISPOSITION OF ASSETS.


             On March 6, 2000, a wholly-owned subsidiary of Zemex Corporation
("Zemex") entered into a stock purchase agreement (the "Stock Purchase
Agreement") whereby it agreed to sell, subject to certain terms and conditions,
all of the outstanding shares of common stock, par value $0.01 per share, of
Pyron Metal Powders, Inc., a Delaware corporation ("Pyron Metal Powders"), and
all of the outstanding shares of common stock, par value $20.00 per share
(together with the Pyron Metal Powder shares, the "Shares"), of Pyron
Corporation, a New York corporation ("Pyron"), to North American Hoganas
Holdings, Inc. ("Hoganas"). Hoganas is a wholly-owned subsidiary of Hoganas AB,
a supplier of metal powders headquartered in Hoganas, Sweden. Pyron and Pyron
Metal Powders comprise the metal powders division of Zemex (the "Metal Powders
Division"), which produces and supplies ferrous and non-ferrous metal powders.
Pursuant to the Stock Purchase Agreement, the Shares were purchased for
approximately $41 million in cash, subject to certain post-closing adjustments.
The amount of consideration was determined through an auction process organized
by Banc of America Securities, LLC, which was retained to review methods and
opportunities to maximize value for the shareholders of Zemex. The sale of the
Shares, which was completed on April 11, 2000, closed as of April 7, 2000.

             Neither Hoganas nor Hoganas AB has any material relationship with
Zemex or any of Zemex's affiliates, any director or officer of Zemex, or any
associate of any such director or officer.
