ITEM 5.  Other Events

On May 16, 2000, Harsco Corporation announced that it agreed with UK-based John
Mowlem & Company plc that Mowlem will, subject to obtaining its stockholders'
approval, sell to a wholly owned subsidiary of Harsco, its entire holding in SGB
Group plc, representing 50.96 percent of the outstanding shares. Harsco said it
will launch a cash tender offer through its wholly owned subsidiary, Harsco
Investment Limited, to acquire all of the shares of SGB. SGB is one of Europe's
largest suppliers of scaffolding, forming and related access products and
services. SGB also has operations in North America, the Middle East and the Asia
Pacific region. For the year ended 31 December 1999, SGB recorded sales of
(pound)283 million (approximately *$417 million).

On May 20, 2000, Harsco Investment Limited issued its offer to the shareholders
of SGB to purchase all of the issued and to be issued share capital for a cash
price of (pound)2.50 (approximately *$3.68) per share. The total transaction
would value SGB at approximately (pound)188 million (approximately *$277
million) for 100 percent of the outstanding shares, plus the assumption of
certain SGB indebtedness, for a total consideration of (pound)222 million
(approximately *$327 million). Harsco has an agreement for bridge loan financing
with The Chase Manhattan Bank for this transaction. Harsco plans to replace
these borrowings with funds from a forthcoming debt issue.

Following Harsco's announcement of the offer, the SGB board of directors issued
a statement which said that it considers the offer to be inadequate and that it
is exploring other alternatives. It recommended that SGB shareholders take no
action on the offer.

Harsco's offer is conditional upon acceptance by at least 90 percent of SGB's
outstanding shares (or such lower percentage as Harsco may decide) as well as
certain other conditions and regulatory clearances. The transaction is expected
to close in the third quarter of 2000.

On May 23, 2000, Mowlem issued notice to its shareholders that Mowlem recommends
approval of the transaction. The notice also announced that Mowlem will hold an
extraordinary shareholders meeting on June 9, 2000 to vote on approval of the
sale.

*Note: Pound sterling amounts are converted to U.S. dollars based upon the May
       25, 2000 published foreign exchange rates. The U.S. dollar amounts
       presented vary from the May 16 press release due to a 2.2% decrease in
       the pound sterling foreign exchange conversion rate.

Forward Looking Statements

The nature of Harsco's and SGB's operations and the many countries in which they
operate subject them to changing economic, competitive, regulatory, and
technological conditions, risks, and uncertainties. In accordance with the "safe
harbor" provisions of the Private Securities Litigation Reform Act of 1995,
Harsco provides the following cautionary remarks regarding important factors
which, among others, could cause future results to differ materially

   3
from the forward-looking statements, expectations, and assumptions expressed or
implied herein. These include statements about our management expectations for
accretiveness of the acquisition, outcome of the offer, and management
confidence and strategies for performance; for market segment and industry
growth.

These factors include, but are not limited to: (1) changes in the worldwide
business environment in which Harsco and SGB operate, including import,
licensing, and trade restrictions, currency exchange rates, interest rates, and
capital costs; (2) changes in governmental laws and regulations, including
taxes; (3) market and competitive changes, including market demand and
acceptance for new products, services, and technologies; (4) effects of unstable
governments and business conditions in emerging economies; and (5) other risk

not intend to update this information and disclaims any legal liability to the
contrary.
