Dear Larry:

This letter confirms Arthur Andersen LLP's (Andersen) arrangements to provide

The Personnel shall report directly and exclusively to Safety-Kleen, and
Safety-Kleen shall be solely responsible for reviewing and approving any and all
work performed by the Personnel. The Personnel shall observe Safety-Kleen's
reasonable policies regarding working conditions and business hours, to the
extent such policies are made known to the Personnel; provided that Andersen's
sole responsibility for the refusal of any Personnel to observe such policies
shall be to furnish Safety-Kleen with replacement Personnel who will observe
such policies.

The Personnel will provide Services at various dates and for various periods
through December 31, 2001 as determined by you, providing the requested
individuals are available. If, for any reason, any Personnel is unable to
complete the service period, or if his (her) performance does not meet your
expectations, we will endeavor to provide a suitable replacement who will be
subject to your approval. If we are unable to identify a replacement acceptable
to Safety-Kleen, the service period will be deemed to have automatically ended
with respect to that individual.

Safety-Kleen shall pay Andersen for the Services at the rates included in the
September 2000 retention order issued by the Bankruptcy Court. The payment
schedule will also be as ordered by the Court.

In addition, Safety-Kleen shall reimburse Andersen for all out-of-pocket
expenses incurred by Andersen or any Personnel in connection with providing the
Services in accordance with Andersen's standard expense policies.
