                            REAFFIRMATION AND CONSENT

     All capitalized terms used herein but not otherwise defined herein shall
have the meanings ascribed to them in that certain Loan Agreement by and among
PHILIP SERVICES CORPORATION, a Delaware corporation ("Parent"), each of Parent's
Subsidiaries identified on the signature pages hereof (such Subsidiaries,
together with Parent, each a "Borrower" and collectively, jointly and severally,
the "Borrowers"), each of the lenders that is a signatory to this Amendment
(together with its successors and permitted assigns, individually, "Lender" and,
collectively, "Lenders"), and FOOTHILL CAPITAL CORPORATION, a California
corporation, as the arranger and administrative agent for the Lenders (in such
capacity, together with its successors, if any, in such capacity, "Agent" and
together with the Lenders, collectively, the "Lender Group"), dated as of March
31, 2001, as amended by that certain Amendment Number One to Loan Agreement
dated as of March 28, 2001 (as amended, restated, supplemented or otherwise
modified, the "Loan Agreement") or in Amendment Number Two to Loan Agreement,
dated as of May 18, 2001 (the "Amendment"), among the Borrowers and Lender
Group. The undersigned hereby (a) represent and warrant to the Lender Group that
the execution, delivery, and performance of this Reaffirmation and Consent are
within its powers, have been duly authorized by all necessary action, and are
not in contravention of any law, rule, or regulation, or any order, judgment,
decree, writ, injunction, or award of any arbitrator, court, or governmental
authority, or of the terms of its charter or bylaws, or of any contract or
undertaking to which it is a party or by which any of its properties may be
bound or affected; (b) consents to the transactions contemplated by the
Amendment; (c) acknowledges and reaffirms its obligations owing to the Lender

Group has no obligations to inform it of such matters in the future or to seek
its acknowledgment or agreement to future amendments, and nothing herein shall
create such a duty. Delivery of an executed counterpart of this Reaffirmation

original executed counterpart of this Reaffirmation and Consent. Any party
delivering an executed counterpart of this Reaffirmation and Consent by
telefacsimile also shall deliver an original executed counterpart of this
Reaffirmation and Consent but the failure to deliver an original executed
counterpart shall not affect the validity, enforceability, and binding effect of
this Reaffirmation and Consent. This Reaffirmation and Consent shall be governed
by the laws of the State of New York.
