FOR IMMEDIATE RELEASE Contact: Maureen Fisk
(847) 468-2452
March 2, 1998 - Elgin, Illinois -- In order to clarify some apparent
confusion, Safety-Kleen Corp. (SK/NYSE) announced today it has not received the
required vote of two-thirds of all outstanding shares necessary to approve
Safety-Kleen's Merger Agreement with SK Parent Corp., a corporation owned
equally by Philip Services Corp., affiliates of Apollo Management L.P. and
affiliates of the Blackstone Group. Both Safety-Kleen and Laidlaw Environmental
are continuing to solicit proxies, and proxies can be revoked (by delivery of
later proxies to Safety-Kleen or Laidlaw Environmental, or by attending and
voting at the special meeting) at any time until the vote is taken at the
special meeting scheduled for March 9, 1998. The results of the solicitation
therefore remain to be determined.
Safety-Kleen is an industrial and environmental service company dedicated
to helping nearly 400,000 automotive and industrial customers process their
waste streams.
