                SAFETY-KLEEN COMMENTS ON PHILIP SERVICES CORP.
                     ANNOUNCEMENT ON FINANCING COMMITMENT

     ELGIN, Ill. - March 5, 1998 - Safety-Kleen Corp. (NYSE:SK) today said it 
believes that concerns about the financing for SK Parent Corp.'s $27 per share 
all-cash merger agreement with Safety-Kleen are effectively addressed by Philip 
Services Corp.'s announcement and the announcement by SK Parent Corp.  After 
giving consideration to Philip's release of its year-end results and copper 
inventory discrepancy, Philip's lender confirmed that nothing has come to its 
attention to date that would cause it not to advance funds.

     On February 20, Philip announced that it had obtained a financing 
commitment from CIBC Capital Partners, a division of Canadian Imperial Bank of 
Commerce ("CIBC") to underwrite a $210 million secured subordinated debt 
facility.  The purpose of the facility is to finance Philip's $200 million 
equity contribution to SK Parent Corp. and to pay certain related fees and 
expenses in connection with the merger agreement.

     Donald W. Brinckman, Safety-Kleen Chairman of the Board and Chief Executive
Officer, said, "Philip's announcement today, coupled with that of SK Parent
Corp. should alleviate concerns about the financing for SK Parent's $27 per
share all-cash offer. Philip has addressed its difficulties and what matters for
the SK Parent transaction is Philip's confirmation that it is in compliance with
the terms of its financing arrangements and the statement of CIBC.

     "Subject to receiving votes for the $27 per share all-cash merger agreement
from holders of two-thirds of Safety-Kleen shares at the shareholders meeting on
March 9, we expect that we can conclude this transaction and that shareholders 
will receive their money promptly after the vote is certified."

     Brinckman further noted that according to information disclosed by Laidlaw 
Environmental, the number of shares tendered to Laidlaw Environmental as of 
March 4 had declined by approximately 13 million shares since February 13, 
evidencing that Laidlaw no longer has tenders from a majority of Safety-Kleen 
shareholders, and that tenders to Laidlaw have, in fact, dropped to 
approximately 31.4 percent.  The closing of Laidlaw Environmental's tender offer
is subject to a condition that two-thirds of Safety-Kleen's shares be tendered. 
Tendering shareholders can also vote in favor of the SK Parent merger.

     Safety-Kleen is an environmental and industrial service company dedicated 
to helping nearly 400,000 industrial and automotive customers recycle and 
process their waste streams.
