ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS.

                  On September 21, 1999 Century Aluminum Company, a Delaware
corporation ("Century" or the "Company"), and Century Aluminum of West Virginia,
Inc., a Delaware corporation and wholly-owned subsidiary of Century ("Century
WV"), completed the sale to Pechiney Rolled Products LLC, a Delaware limited
liability company ("Pechiney"), of certain assets and the assumption of certain
liabilities of Century WV's rolled products unit at Ravenswood, West Virginia
(the "Rolling Business") and all of the issued and outstanding shares of common
stock of Century Cast Plate, Inc., a Delaware corporation and wholly-owned
subsidiary of Century ("Century CP"). The parties consummated the sale pursuant
to the Stock and Asset Purchase Agreement dated July 26, 1999 (the "Purchase
Agreement") by and among Century, Century WV and Pechiney. The aggregate
purchase price for the Rolling Business and Century CP was $248 million, subject
to certain post-closing adjustments. The purchase price was determined by
arms'-length negotiations between the parties. Century used a portion of the
purchase price to repay its outstanding debt.

                  The Rolling Business assets that were sold include Century
WV's casting operation at the Ravenswood, West Virginia facility. The facility,
which has the capacity to produce up to 600 million pounds (270,000 metric
tons) of rolled aluminum products a year, provides premium sheet and plate
products to the aerospace and transportation markets, and produces brazing
sheet used to manufacture radiators for passenger cars and trucks.

                  Century CP's operations include a fabrication plant located in
Vernon, California. The fabrication plant has the capacity to produce 15 million
pounds (7,000 metric tons) a year of cast aluminum plate. Cast aluminum plate is
used principally in the machinery and equipment market.

                  In connection with the Purchase Agreement, Century WV and
Pechiney entered into a Molten Aluminum Purchase Agreement dated as of September
21, 1999 (the "Metal Agreement"). Pursuant to the Metal Agreement, Pechiney has
agreed to purchase from Century WV substantial quantities of molten aluminum
produced at Century WV's reduction facility in Ravenswood, West Virginia at a
price which is based on a quoted average market price as reported for the month
immediately preceding the month of delivery. In addition, Pechiney has agreed to
provide casting services to Century WV in connection with the excess molten
aluminum produced at Century WV's reduction facility which is not purchased by
Pechiney under the Metal Agreement. In connection with the transition of
ownership of the Rolling Business, Century has agreed to make available certain
of its executive officers to provide consulting services to Pechiney.
