          This EMPLOYMENT TERMINATION AND CONSULTING AGREEMENT (the "Agreement")
is  dated  as  of  August  15,  2001  between  Safety-Kleen  Corp.,  a  Delaware
corporation (including its successors and assigns, the "Company"), and Grover C.
Wrenn,  a  Florida  resident  (the  "Executive").

          WHEREAS, the Executive currently serves as the Chief Operating Officer
and  President and member of the Board of Directors (the "Board") of the Company
pursuant to an Employment Agreement dated as of August 23, 2000 (the "Employment
Agreement"), and the United States Bankruptcy Court for the District of Delaware
(the  "Bankruptcy  Court")  entered  an Order on August 11, 2000 authorizing the
Company  to  enter  into  said  Employment  Agreement;

          WHEREAS, the Company and Executive desire to enter into this Agreement
to  confirm  the  Executive's and Company's rights and obligations in connection
with  the  Executive's  termination  of  his employment with the Company and its
subsidiaries  and  affiliates under the Employment Agreement, except for certain
continuing  provisions  and  future  obligations;

          NOW,  THEREFORE,  in  consideration  of the mutual covenants set forth
below,  the  Executive  and  the  Company  agree  as  follows:

          1.     Effective  Date and Termination of Employment.  Notwithstanding
                 ---------------------------------------------
anything herein to the contrary, the "Effective Date" of this Agreement shall be
the  date  this  Agreement  has been fully executed by both parties and has been
approved by the Bankruptcy Court, and this Agreement shall not be binding on the
parties  hereto  until  the Effective Date.  As of the Effective Date, Executive
resigns as President and as Chief Operating Officer of the Company, and from all
employment  positions  with the Company and its subsidiaries; provided, however,
that  Executive is not resigning as a member of the Board and as a Vice-Chairman
of  the  Board.

          2.     Continued  Services.  As  of  the  Effective Date, Executive is
                 -------------------
hereby  designated, and shall be elected, as a Vice-Chairman of the Board of the
Company  and,  in  such  capacity,  Executive shall report directly to the Chief
Executive  Officer/Chairman  of  the  Board (the "CEO/Chairman") of the Company.
Subject to the payment of the "Per Diem Fee" (as hereinafter defined), Executive
shall,  in  his  capacity  as  a  Vice-Chairman,  render such services as may be
reasonably  requested  by  the CEO/Chairman, and at times and locations that are
mutually  agreeable to the Company and Executive, in connection with the sale of
the  waste  management  business  of  the  Company,  any  environmental  matters
pertaining  to  the Company or any of its subsidiaries, any criminal proceedings
against  the  Company  and  any  and  all other claims or litigation against the
Company, or its directors or officers.  In connection with services requested by
the  CEO/Chairman,  Executive shall be paid a consulting fee of up to $2,500 per
day, or portion thereof, (the "Per Diem Fee") as determined by the CEO/Chairman,
provided that such Per Diem Fee continues to be satisfactory to the CEO/Chairman
and  Executive.  Executive  shall also be reimbursed for all reasonable business
expenses,  in  each  case  subject  to  such  documentation  as  the Company may


<PAGE>
reasonably request.  Under this Agreement, Executive shall not be reimbursed for
any  reimbursable  business expense in excess of a reasonable threshold selected
by  the  CEO/Chairman,  but  in  any  event not less than $500 per such expense,
without  prior  authorization  of the CEO/Chairman.  In rendering such services,
Executive  shall  be an independent contractor consultant to the Company and not
an  employee  of  the  Company.  Executive  is  free  to  pursue such full-time,
part-time  or  other  employment or consulting opportunities as he shall desire.
Executive  shall  receive his Per Diem Fee and expense reimbursements payable in
accordance  with  the Company's normal payroll practices, but no less frequently
than  monthly.  To  the  extent  necessary  in  connection  with the Executive's
services  hereunder,  the  Company  shall make available to Executive reasonable
office  facilities  and secretarial assistance in the Company's existing offices
in  Tampa,  Florida.


          3.     Termination  Compensation.  Subject  to  the payment of, and in
                 -------------------------
consideration  of, the bonus payment pursuant to Section 4 of this Agreement and
the  other  Company's  obligations  pursuant  to  Section  5  of this Agreement,
Executive  hereby  waives any rights to any other severance benefits to which he
might  otherwise  be  entitled under the Employment Agreement.  Without limiting
the  foregoing,  Executive  acknowledges and agrees that he will not receive any
severance  or  bonus payments pursuant to the terms of the Employment Agreement,
other  than  as  required  to  be paid pursuant to Sections 4 and 5 hereof.  The
Company  shall  pay  to  Executive,  in  accordance  with  its customary payroll
practices, an amount equal to Executive's accrued and unpaid salary, accrued and
unused  vacation  and  other  reimbursable  expenses  through the Effective Date
pursuant  to  Executive's  Employment  Agreement  in  full satisfaction thereof.
Except  as  provided  in  this  Agreement,  and  except  for any compensation or
benefits  offered to Board members, Executive shall not be entitled to any other
compensation  or  benefits  from  the  Company.


          4.     Plan  of  Reorganization/Sale  Bonus.  In  consideration of the
                 ------------------------------------
waiver  pursuant  to  Section 3 hereof, the Company shall pay, and the Executive
shall  receive: (a) a cash lump sum payment of $625,000 on the Effective Date of
this  Agreement;  and  (b)  an  additional  lump sum payment in cash of $625,000
within fifteen (15) days of the earlier to occur of: (i) the effective date (the
"Reorganization  Plan  Effective  Date")  of  a  plan  of reorganization for the
Company  under  Chapter  11  of  the  Bankruptcy  Code;  or  (ii)  a "Triggering
Transaction" (as hereinafter defined).  A "Triggering Transaction" is defined as
the date of the consummation of the sale, transfer or other disposition, whether
in  one  transaction  or a series of transactions, and whether or not done as an
asset sale or a sale of stock of a subsidiary or merger or consolidation, of all
or substantially all of the "Operating Assets of the Chemical Services Division"
(as  hereinafter  defined)  of  the  Company.  For  purposes  hereof,  the  term
"Operating  Assets  of  the Chemical Services Division" shall mean those ongoing
operating  assets  of  the  Company's  Chemical  Services Division, as currently
defined  by  the  Company,  and  expressly  excludes  any assets associated with
"permitted sites" or other regulated operations where commercial operations have
ceased  or  which are either closed or in the process of being closed within the
next  twelve  (12)  months.
