         53. Pursuant to 40 C.F.R. ss.761.65(g), a commercial storer of PCB
waste shall establish financial assurance for the closure of each PCB storage

to modify or alter the  requirements  for closure in  accordance  with 40 C.F.R.
ss.761.65(e).  EPA may determine in its sole  discretion and in accordance  with
applicable law to modify the requirements of this Paragraph.  EPA agrees that if
the  Bankruptcy  Case is still  open or pending  then any action  that it brings
against  Respondents  under this Consent Agreement to enforce the requirement of
this  Paragraph  that  Respondents  initiate  closure  shall be  brought  in the

Financial  Assurance,  Respondents  shall meet with EPA,  and the  Participating
State(s) if appropriate, to discuss the requirements of this paragraph; however,
the  pendency  of  these  discussions  shall  not  excuse  or delay  the  timely
performance of required corrective action with applicable law and permits.  EPA,
in consultation with the affected States, may determine in its discretion and in
accordance with applicable law to modify the requirements of this Paragraph. EPA
agrees that if the Bankruptcy Case is still open or pending then any action that
it brings against Respondents under this Consent Agreement to enforce the


<PAGE>

                                       34

requirement of this Paragraph that Respondents initiate corrective action shall
be brought in the Bankruptcy Case. However, EPA reserves whatever rights it has
to enforce any Environmental Law, including for corrective action, against
Respondents in any court that would have jurisdiction to enforce such
Environmental Law in the absence of this Consent Agreement.

        92. If, prior to obtaining Compliant Financial Assurance, Respondents
enter into an agreement with any of the fifty States providing for a letter of
credit or other security interest to supplement or replace financial assurance
for any facility owned or operated by Respondents where Respondents' financial
assurance is in the form of a Frontier surety bond, Respondents shall provide
EPA and the Participating States the same pro rata amount of supplemental
security interest protection based on the respective amounts of Frontier bonds.

        93. Respondents shall comply with all permit requirements for Covered
Facilities, including but not limited to, limitations on the maximum amount of
waste allowed at a Covered Facility. Until such time as Respondents obtain
Compliance Financial Assurance, Respondents shall also ensure that the amount
of waste stored or awaiting disposal or treatment at a Covered Facility does
not exceed the normal historical amounts of such hazardous waste
during the year prior to Respondents' filing for bankruptcy.

         94. Respondents shall require that any agreement for the sale, lease or
other transfer of a Covered Facility provides that nothing in the agreement or
the Court order approving the agreement shall be construed to release or relieve
any entity of any liability to a governmental entity under any police and
regulatory statute as the owner or operator of property that that entity owns or
operates after the date of transfer. Respondents shall comply with 40 C.F.R.
ss.270.40 (transfer of permits), or the applicable authorized state
requirements, to the extent that it is not altered by the following: that until
such time as Respondents obtain Compliant Financial

Assurance,  Respondents shall not enter into any agreement for the transfer
of a Covered  Facility  unless  the new owner  and/or  operator  of the  Covered
Facility,  prior to the  transfer of  ownership  or  operational  controls,  has
received  approval in writing from EPA and any  applicable  Participating  State
that  the  new  owner  and/or  operator  is in  compliance  with  the  financial
responsibility and assurance requirements of 40 C.F.R. Part 264 and 265, Subpart
H or the  applicable  authorized  state  requirement.  Nothing in this Paragraph
relieves Respondents of their obligation to comply with applicable Environmental
Laws.

         95. If during the Interim Compliance Period, Respondents determine that
they need to shut down the operations of one or more of the Covered Facilities
Respondents shall, in addition to complying with other applicable legal
requirements, notify EPA and the Participating States at least ten days prior to
the cessation of operations at the Covered Facility(ies) so that EPA and
the Participating States can provide comments regarding the timing and
prioritization of operational shutdown of the Covered Facilities in accordance
with applicable law. Incorporation of these comments into the Respondents' final
plan for implementing the shutdown of operations at the one or more Covered
Facilities shall be subject to the consent of Respondents, which consent shall
not be unreasonably withheld. Nothing in this Paragraph relieves Respondents of
their obligation to comply with applicable law.

         96. If during the Interim Compliance Period, EPA or a Participating
State determines that one of the Covered Facilities is in significant
non-compliance, EPA's Office Director, Office of Regulatory Enforcement, in
consultation with the affected Participating State, may notify Respondents that
this Consent Agreement no longer includes such Covered Facility within the terms
of the Consent Agreement.

         97. Respondents shall comply with the provisions and terms of the

Management Systems Analysis will be commenced by September 15, 2000 and shall be
completed by May 15, 2001.

         98. Respondents shall comply with the terms and provisions of the

within their control to keep current their surety bonds with Frontier Insurance
Company for the Covered Facilities until such time as Respondents are able to
provide Compliant Financial Assurance for those Covered Facilities.

         100. Except as stated in this Paragraph 100, all claims or rights to
injunctive relief of EPA and any Participating States against any Respondent for
Environmental Cleanup or Response Cost Liabilities shall not be discharged or

                                       37

commenced,   and  may  then  be   determined  in  the  manner  and  by  the
administrative  or  judicial  tribunals  in  which  such  claims  or  rights  to
injunctive relief would have been resolved or adjudicated if the Bankruptcy Case
had not been commenced.  This Paragraph 100 applies to all Environmental Cleanup
or Response Cost Liabilities of Respondents to EPA and any Participating  States
and is not limited to  liabilities  related to Covered  Facilities or facilities
located in  Participating  States or Parallel Action States.  Respondents  agree
that any bar date for filing  claims in the  Bankruptcy  Case shall not apply to
claims covered by this Paragraph 100.

     This  Paragraph  100 does not  apply to (i) any  Environmental  Cleanup  or
Response Cost  Liability of any  Respondent  for a money  judgment that EPA or a
Participating  State has obtained prior to confirmation of a reorganization plan
in the  Bankruptcy  Case;  or (ii) any  Environmental  Cleanup or Response  Cost
Liability that EPA or a  Participating  State seeks by filing an action or claim
in a court or  administrative  forum prior to confirmation  of a  reorganization
plan in the  Bankruptcy  Case,  if  such  asserted  Liability  would  prevent  a
Respondent from  reorganizing.  Respondents  agree that any general bar date for
filing claims in the Bankruptcy  Case shall not apply to claims within  subparts
(i) and (ii) of the foregoing  sentence.  If  Respondents  wish to assert that a
claim falls within subpart (i) or (ii), Respondents must establish a special bar
date for claims  within  subparts  (i) and (ii) and send out a special  bar date
notice  that  specifically  identifies  all such  claims by case name and docket
number  that it  believes  fall  within  subparts  (i) and (ii).  Nothing in the
foregoing  abrogates  or  diminishes  any rights that EPA and the  Participating
States have in the absence of this Consent Agreement.  EPA and the Participating
States may contest  Respondents'  contention  that a claim falls within subparts
(i) and (ii) and the Bankruptcy Court shall have exclusive jurisdiction over the
determination  of whether or not the claims fall within subparts (i) or (ii) for
purposes of determining the applicability of this

Paragraph 100.

        In addition, because the State of South Carolina has indicated it will
not be a Participating State or Parallel Action State for facilities owned
and/or operated by Safety-Kleen (Pinewood), Inc., this Paragraph 100 does not
apply to Environmental Cleanup or Response Cost Liabilities of Respondents to
the State of South Carolina for facilities owned and/or operated by Safety-
Kleen (Pinewood), Inc. This Paragraph 100 does apply to Environmental Cleanup or
Response Cost Liabilities of Respondents to EPA for facilities owned and/or
operated by Safety-Kleen (Pinewood), Inc. Nothing in this Paragraph 100
abrogates any rights by and between the State of South Carolina and Respondents
that exist in the absence of this Consent Agreement or expresses in any way
EPA's views on Adversary Proceeding No. 00-698 between South Carolina and
Respondents and this Consent Agreement may not be used as evidence of EPA's
views in Adversary Proceeding No. 00-698.

         101. In the event that Respondents are unable to obtain Compliant
Financial Assurance for any of the Covered Facilities by the Compliant Financial
Assurance Deadline, the Respondents agree that they shall comply with the
requirements for closure, post-closure, and corrective action set forth in
Paragraphs 89-91. Under no circumstances while the Bankruptcy Case is pending or
open, shall any Respondent file a motion, adversary proceeding, or other request
with the Bankruptcy Court or any other court under Section 105 of the Bankruptcy
Code or any other authority that seeks to delay or avoid Respondents' compliance
with the requirements for closure, post-closure, and corrective action set forth
in Paragraphs 89-91 or that contends in any way that any action by EPA or the
Participating States to enforce closure, post-closure, and corrective action
requirements as permitted by Paragraphs 89-91 is not within the police and
regulatory exception to the automatic stay. 11 U.S.C. ss.362(b)(4). Respondents
also

                                       39

agree to  oppose  as  being  inconsistent  with  this  Consent  Agreement  any
motion, adversary proceeding, or other request by other parties in interest with
the Bankruptcy Court or any other court under Section 105 of the Bankruptcy Code
or any other authority that seeks to delay or avoid Respondents' compliance with
the requirements for closure,  post-closure,  and corrective action set forth in
Paragraphs  89-91 or that  contends  in any way that  any  action  by EPA or the
Participating  States to enforce closure,  post-closure,  and corrective  action
requirements  as  permitted  by  Paragraphs  89-91 is not  within the police and
regulatory  exception to the automatic stay. 11 U.S.C.  ss.362(b)(4).  Except as
provided in Paragraph  100 with respect to EPA,  Respondents  reserve all rights
related to facilities  owned and/or  operated by Safety-Kleen  (Pinewood),  Inc.
Nothing in this Paragraph abrogates any rights by and between the State of South
Carolina and Respondents that exist in the absence of this Consent  Agreement or
expresses  in any way EPA's views on Adversary  Proceeding  No.  00-698  between
South  Carolina and  Respondents  and this Consent  Agreement may not be used as
evidence of EPA's views in Adversary Proceeding No. 00-698.

        102. Respondents shall comply in full with all Environmental Compliance
Obligations throughout the Bankruptcy Case. Under no circumstances, while the
Bankruptcy Case is pending or open, shall any Respondent file a motion,
adversary proceeding, or other request with the Bankruptcy Court or any other
court under Section 105 of the Bankruptcy Code or any other authority that seeks
to delay or avoid Respondents' Environmental Compliance Obligations or contends
that any action by EPA or the Participating States to enforce an Environmental
Compliance Obligation is not within the police and regulatory exception to
automatic stay. 11 U.S.C. ss.362(b)(4). Respondents also agree to oppose as
being inconsistent with this Consent Agreement any motion, adversary proceeding,
or other request by other parties in interest with


<PAGE>


                                       40

the  Bankruptcy  Court or any  other court  under Section 105 of  the Bankruptcy
Code or any  other  authority  that  seeks  to  delay  Environmental  Compliance
Obligations  or contends that any action by EPA or the  Participating  States to
enforce  Environmental  Compliance  Obligations  is not  within  the  police and
regulatory exception to automatic stay. 11 U.S.C.  ss.362(b)(4).  This Paragraph
applies to all  Environmental  Compliance  Obligations of Respondents and is not
limited to Environmental Compliance Obligations related to Covered Facilities or
facilities  located in  Participating  States or Parallel Action States,  except
that this  Paragraph  does not apply to  facilities  owned  and/or  operated  by
Safety-Kleen  (Pinewood),  Inc. EPA reserves  all rights  related to  facilities
owned and/or  operated by  Safety-Kleen  (Pinewood),  Inc. Except as provided in
Paragraph  100 with respect to EPA,  Respondents  reserve all rights  related to
facilities  owned  and/or  operated by  Safety-Kleen  (Pinewood),  Inc. and this
Paragraph does not apply to such facilities. Nothing in this Paragraph abrogates
any rights by and between the State of South Carolina and Respondents that exist
in the absence of this Consent  Agreement or expresses in any way EPA's views on
Adversary  Proceeding No. 00-698 between South Carolina and Respondents and this
Consent  Agreement  may not be used as  evidence  of EPA's  views  in  Adversary
Proceeding No. 00-698.

         103. Respondents shall not abandon any Covered Facility if such Covered
Facility does not have Compliant Financial Assurance. EPA and the Participating
States also reserve all rights to contest any proposed abandonment on any other
ground under applicable law.

         104. Whenever this Consent Agreement requires Respondents to submit a
report or documentation regarding their compliance with Environmental Laws or
under Paragraph 88(b), it shall be signed and certified as accurate by a
responsible corporate officer as defined by 40 C.F.R. ss.270.11(a)(1), or
his/her duly authorized representative. This certification shall include

the following language:

         107. Upon the effective date of this Consent Agreement, Respondents
agree to provide EPA access at all reasonable times to any of the Covered
Facilities, and any other property owned, operated or controlled by Respondents,
to which access is required for the implementation of this Consent Agreement for
the purposes of conducting any activity related to this Consent Agreement,
including but not limited to:

                  a.       monitoring all work and activities required by this
                           Consent Agreement;

                  b.       verifying any data or information submitted to EPA;

                  c.       conducting investigations relating to work or

                           contracts, or other documents maintained or generated
                           by Respondents or their agents related to work or

                  f.       assessing Respondents' compliance with this Consent
                           Agreement.

         108. Upon the effective date of this Consent Agreement, Respondents
agree to provide Participating States access at all reasonable times to any of
the Covered Facilities located in their state, and any other property owned,

                           Consent Agreement;

                  d.       obtaining samples relating to work or activities
                           required by this Consent Agreement;

                  e.       inspecting and copying records, operating logs,
                           contracts, or other documents maintained or generated
                           by Respondents or their agents related to work or
                           activities required by this Consent Agreement; and

                  f.       assessing Respondents' compliance with this Consent
                           Agreement.

                            VIII. PAYMENT OF PENALTY

         109. Respondent Safety-Kleen Services, Inc. agrees to pay a civil
penalty in the sum of $184,692.00. 40 C.F.R. ss.22.18(b). Respondents agree to
pay this amount as an Allowed Administrative Expense Claim in the Bankruptcy
Case as of the Effective Date of the Plan of Reorganization and in the same
manner as other Allowed Administrative Expense Claims are paid. EPA's Allowed
Administrative Expense Claim shall not be subordinated for any reason to other
Allowed Administrative Expense Claims in the Bankruptcy Case. It is EPA's
position that it has substantially reduced the amount of penalty for which
Respondents would otherwise be liable on account of Respondents' limited ability
to pay.

         110. Respondent, Safety-Kleen Services, Inc., shall pay the civil
penalty by certified or cashier's check and make it payable to "Treasurer,
United States of America," and mailed to:

               U.S. Environmental Protection Agency
               Hearing Clerk
               P.O. Box 360277M
               Pittsburgh, PA  15251

The check should indicate that it is for "Safety-Kleen Corp., et al.," and shall
indicate the docket number for this administrative action.


<PAGE>


                                       44

         111. A transmittal letter, indicating Respondent, Safety-Kleen
Services, Inc., complete address, and case docket number shall accompany each
payment.

         112. Respondent Safety-Kleen Services, Inc., shall send a copy of the
checks and transmittal letters to:

               Clerk, Environmental Appeals Board
               U.S. Environmental Protection Agency
               1200 Pennsylvania Avenue, N.W. (1103-B)
               Washington, DC  20460
and

               Christine J. McCulloch, Esq.
               Office of Regulatory Enforcement
               U.S. Environmental Protection Agency
               1200 Pennsylvania Avenue, N.W. (2246-A)
               Washington, DC  20460

         113. Failure to pay the full amount of the penalty assessed under this
Consent Agreement may subject Respondent Safety-Kleen Services, Inc. to a civil
action to collect any unpaid portion of the proposed civil penalty and interest,
as set forth in Paragraph 114, below. In any such collection action, the
validity, amount and appropriateness of this Consent Agreement or the settlement
payment, or penalty assessed hereunder are not subject to review.

         114. If Respondent Safety-Kleen Services, Inc. fails to remit the civil
penalty as agreed to herein, EPA is required to assess interest and penalties on
debts owed to the United States and a charge to cover the cost of processing and
handling a delinquent claim. Interest, at the statutory judgment rate provided
for in 31 U.S.C. ss.3717, will therefore begin to accrue on the civil penalty
if it is not paid within thirty (30) calendar days from when due under this
Consent Agreement.

         115. Penalties paid pursuant to this Consent Agreement are not
deductible for federal tax purposes under 28 U.S.C. ss.162(f).

                            IX. STIPULATED PENALTIES

         117. All stipulated penalties begin to accrue on the day that
performance is due or a noncompliance occurs, and continue to accrue through the
earlier of: (i) the final day of all correction of the noncompliance, or (ii)
the time through which an analogous penalty under applicable law would accrue.
Nothing herein shall preclude the simultaneous accrual of separate stipulated
penalties for separate violations of this Consent Agreement.

         118. Respondents shall notify EPA in writing of any failure to meet
Consent Agreement requirements for which stipulated penalties may be due as soon
as they have knowledge of such failure. EPA shall notify Respondents as soon as
practicable of any alleged failure by Respondents to meet Consent Agreement
requirements for which stipulated penalties may be due. EPA reserves the right
to demand payment of stipulated penalties upon a determination by EPA that a
violation of this Consent Agreement has occurred. However, penalties shall
accrue as provided in Section IX, regardless of whether Respondents or the EPA
has notified the other of a violation.

         119. The payment of stipulated penalties shall not alter in any way
Respondents' obligation to comply or complete the terms of the Consent
Agreement.

         120. All penalties owed to the EPA under this Section shall have
administrative expense priority and shall be paid as of the Effective Date of
the Plan of Reorganization and in the same manner as other allowed
administrative expense claims are paid in the Bankruptcy Case. EPA's allowed
administrative expense claims shall not be subordinated for any reason to other
allowed administrative expense claims in the Bankruptcy Case. Respondents may
contest the amount of any administrative expense claimed by EPA for stipulated
penalties under this Consent Agreement but may not contest the administrative
priority of any claim allowed. All payments under this Section shall be paid by
certified or cashier's check made payable to
the "Treasurer of

the United States" and shall be mailed with a cover letter stating the caption
and docket number of this administrative case to:

               Hearing Clerk
               P.O. Box 360277M
               Pittsburgh, PA  15251

The check should also indicate that it is for "Safety-Kleen Corp., et. al.," and
should reference the docket number for this administrative action.

         121. Respondents shall send a copy of the checks and transmittal
letters to:

               Clerk, Environmental Appeals Board
               U.S. Environmental Protection Agency
               1200 Pennsylvania Avenue, N.W. (1103-B)

               Washington, DC  20460

         122. If Respondents fail to pay stipulated penalties when due, the EPA
may institute proceedings in Bankruptcy Court to collect the penalties, as well
as interest. Respondents shall pay interest on the unpaid penalties at the rate
established by the Secretary of Treasury pursuant to 31 U.S.C. ss.3717,
beginning on the date of demand made pursuant to Section IX, and shall continue
to accrue at the rate specified through the date of the Respondents' full
payment. Such interest shall be compounded each federal fiscal year.

         123. Nothing in this Section shall be construed as prohibiting,
altering or in any way limiting the ability of the EPA to seek other remedies or
sanctions available by virtue of Respondents' violation(s) of this Consent
Agreement or of the statutes and regulations referenced herein.

Agreement.

deductible for federal tax purposes under 28 U.S.C. ss.162(f).

                                X. CERTIFICATION

         126. Nothing in this Consent Agreement shall relieve Respondents of the
duty to comply with all applicable provisions of RCRA and TSCA, and other
federal, state or local laws or statutes, nor shall it restrict EPA's (or the
Participating States') authority to seek compliance with any applicable laws or
regulations, nor shall it be construed to be a ruling on, or determination of,
any issue related to any federal, state or local permit. Nothing in this
Paragraph shall be construed to modify or vacate the provisions of this Consent
Agreement providing for a Compliance Schedule for Respondents to obtain
Compliant Financial Assurance by the Compliant Financial Assurance Deadline.

         127. Respondents shall comply with all applicable requirements of RCRA
and TSCA, and regulations thereunder at 40 C.F.R. Parts 260-270 and 761, and as
applicable, authorized state programs, provided that in the event that
Respondents do not obtain Compliant Financial Assurance by the Compliant
Financial Assurance Deadline, Respondents shall comply with the
requirements of Paragraphs 89-91 of this Consent Agreement. Respondents agree to
undertake all necessary actions to prevent recurrences of violations of
environmental requirements. Nothing in this Paragraph shall be construed to
modify the provisions of this Consent Agreement providing for a Compliance
Schedule for Respondents to obtain Compliant Financial Assurance by the


<PAGE>


                                       50

Compliant Financial Assurance Deadline.

         128. By signing this Consent Agreement, Respondents certify that the
information it has supplied concerning this matter was at the time of
submission, and is, truthful, accurate, and complete for each such submission,
response and statement. Respondents realize that there are significant penalties
for submitting false or misleading information, including the possibility of
fines and/or imprisonment for knowing submission of such information, 18 U.S.C.
ss.1001.

         129. EPA reserves the right to revoke this Consent Agreement and
accompanying settlement penalty if and to the extent that any information or
certification provided by Respondents was materially false or inaccurate at the
time such information or certification was provided to EPA, and EPA reserves the
right to assess and collect any and all civil penalties for any violation
described herein. EPA shall give Respondents oral notice of their intent to
revoke which shall not be effective until received by Respondents in writing.

         130. Participating States reserve the right to consult with and request
that EPA revoke that portion of the Consent Agreement for Covered Facilities in
Participating States and accompanying settlement penalty if and to the extent
that any information or certification provided by Respondents, was materially
false or inaccurate at the time such information or certification was provided
to EPA, and EPA reserves the right to assess and collect any and all civil
penalties for any violation described herein. EPA shall give Respondents oral
notice of their intent to revoke which shall not be effective until received by
Respondents in writing.

                            XI. EFFECT OF SETTLEMENT

         131. This Consent Agreement and the accompanying Final Order resolve
only those civil claims specified in Section VI above arising prior to Compliant
Financial Assurance Deadline. Nothing herein shall be construed to limit the
authority of EPA, the United States and/or the


<PAGE>

                                       51

Participating States to undertake action against any person,  including the
Respondents,  in response to any  condition  which EPA, the United States or the
Participating   States   determine  may  present  an  imminent  and  substantial
endangerment  to the  public  health,  welfare  or the  environment,  nor  shall
anything in this Consent Agreement or the accompanying  Final Order be construed
to resolve,  and the EPA, United States and  Participating  States reserve their
authority to pursue criminal sanctions against Respondents.

         132. This Consent Agreement, upon incorporation into a Final Order by
the Environmental Appeals Board and full satisfaction by the parties, shall be a
complete and full civil settlement of the specific violations set forth in
Section VI, above.

                     XII. MODIFICATION OF CONSENT AGREEMENT

     133. EPA may supplement the list of Participating  States,  Parallel Action
States,  and Covered Facilities by providing notice to Respondents by August 31,
2000. No such  supplementation  shall alter the provisions in Paragraphs 100-102
for facilities  owned and/or  operated by Safety-Kleen  (Pinewood),  Inc. If EPA
provides  such notice,  the civil  penalty  required by  Paragraph  109 shall be
increased by $4,062.00 per violation  for the  noncompliances  identified by the
Participating  State. No change will be made to the Civil Penalty required under
this Consent Agreement for the addition of Parallel Action States, although such
States may require a civil penalty under any parallel agreement.  It is possible
that future  circumstances  may be such that  Respondents  may choose to request
that  EPA  (and  affected  States)  extend  the  Complaint  Financial  Assurance
Deadline.  Any  decision  by EPA  relating  in any way to extend  the  Complaint
Financial Assurance Deadline shall be in its sole discretion (after consultation
with the  affected  States)  and will not be subject  to  judicial  review.  Any
decision  by the EPA to allow an  extension  of time will  require  that such an
extension be put in writing and signed by the
<PAGE>

                                       52

Parties. Any decision by EPA (and the affected States) to extend
the Compliant Financial Assurance Deadline for a period of time no later than
April 30, 2001 will not require further approval by the Bankruptcy Court. Except
as specifically provided herein, there shall be no modifications or amendments
of this Consent Agreement without the written agreement of the parties to this
Consent Agreement and after consultation with the Participating States.

                 XIII. SUBMITTAL TO ENVIRONMENTAL APPEALS BOARD

         134. The Parties agree to submit this Consent Agreement to the
Environmental Appeals Board with a request that it be incorporated into a Final

Agreement. Such approval shall specifically include the Court's approval of the
provisions contained in Section VII (Terms of Agreement), Section VIII (Payment
of Penalty), Section IX (Stipulated Penalties), and Paragraphs 100-103.

                               XV. EFFECTIVE DATE

        Pursuant to the Consent Agreement, and in connection its negotiation,
Debtors have produced and will produce documents and information to the United

be confidential and proprietary under applicable law, including 40 C.F.R.
Part 2. To protect Debtors' interest in maintaining the confidentiality of such

               a. If Debtors seek confidential treatment of a document, they
        shall stamp the word "CONFIDENTIAL" conspicuously on each page of the
        document. The transmittal of information designated as confidential
        shall be done by letter to the United States and the Participating
        States stating that the information is designated as confidential.

               b. The United States and Participating States shall not use
        documents and information designated as confidential pursuant to this

        Case, or any other legitimate law enforcement


<PAGE>


         governmental purpose. This Order binds any person to whom such
         disclosure is made.

                d. Any person who obtains access to information designated as
         confidential information under this Order may make copies, duplicates,
         extracts, summaries, or descriptions of the information or any portion
         thereof only for work relating to the Consent Agreement, the Bankruptcy
         Case, or any other legitimate law enforcement governmental purpose. All
         copies, duplicates, extracts, summaries or descriptions shall be
         subject to the terms of this Protective Order to the same extent and
         manner as original documents.

                e. Any information designated as confidential information under
         this Order that is filed with any Court shall be filed in sealed

                    ENVIRONMENTAL MANAGEMENT SYSTEMS ANALYSIS

        This Attachment I sets forth the terms and provisions of the
"Environmental Management Systems Analysis" referred to in Paragraph 97 of the
Consent Agreement. The definitions in the Consent Agreement apply to this
Attachment. Additional definitions for this Attachment are set forth herein.

        EPA acknowledges that the deadlines set forth in this Attachment and the
Consent Agreement for this Environmental Management Systems Analysis are
predicated upon Respondents' obtaining Bankruptcy Court approval for the Consent
Agreement and retention of the Consultant Auditor (defined in paragraph 2 below)
in early September 2000. If Bankruptcy Court approval is delayed, EPA agrees
that one or more of the deadline(s) associated with this Environmental
Management Systems Analysis may need to be extended, and EPA agrees to consider
the fact of delayed Bankruptcy Court approval in good faith in determining
whether to extend any deadline. Respondents agree to exercise their best efforts
to obtain final Bankruptcy Court approval of the Consultant Auditor if they
determine such approval is necessary.

        1. EPA is requiring the Environmental Management Systems Analysis to
assess Respondents' current corporate-wide environmental management systems
("EMS"). To achieve this purpose, an independent, third-party entity, acceptable
to EPA (in consultation with the Participating States) will assess Respondents'
EMS using the elements listed in Appendix I-1.

        2. No later than September 1, 2000, Respondents shall provide to EPA in
writing (i) the name and address of the person or entity that it proposes to
conduct the Environmental Compliance Audit ("Consultant Auditor"); and (ii) the
Consultant Auditor's qualifications relevant to performing to Environmental
Management Systems Analysis, including, as appropriate, the Consultant Auditor's
satisfaction of the proficiency criteria described in ISO 14012 "Guidelines for
Environmental Auditing - Qualification Criteria for Environmental Auditors."

        3. The Consultant Auditor may have no financial or other conflict of
interest that would prevent it from exercising independent judgment and
discipline analogous to that which a certified public accounting firm would be
expected to exercise in auditing a publicly-held corporation. If the Consultant
Auditor already is under contract to Respondents, Respondents must disclose this
to EPA. Additionally, Respondents shall disclose to EPA any long term or
significant contractual relationship they have had with the Consultant Auditor
since January 1, 1998.

        4. After consulting with the Participating States, EPA will notify
Respondents promptly whether EPA approves the retention of the proposed
Consultant Auditor. If EPA disapproves the proposed Consultant Auditor,
Respondents must propose another Consultant Auditor within fifteen (15) calendar
days, and the commencement and conclusion dates for the Environmental Management
Systems Analysis set forth in Paragraph 97 of the Consent Agreement will be


<PAGE>


deemed adjusted accordingly.

         5. Thirty (30) calendar days after its retention, the Consultant
Auditor will submit a proposed work plan to EPA and the Participating States for
the Environmental Management Systems Analysis. The work plan will set forth the

relative to the key elements listed in Appendix I-1.

         6. After consulting with the Participating States, EPA will provide
comments on the work plan within ten (10) working days of receiving it.
Respondents also may comment on the work plan. The Consultant Auditor shall have
ten (10) working days to incorporate Respondents' and EPA's comments into the
work plan or explain in the work plan why the comments have not been
incorporated. If EPA is not satisfied with Consultant Auditor's explanation for
the failure to incorporate EPA's comments, EPA will promptly notify the
Consulting Auditor and Respondents and will reserve all rights with respect to
whether the resulting Environmental Management Systems Analysis has satisfied
Paragraph 97 of the Consent Agreement.

         7. Respondents will provide any documents that the Consultant Auditor
requests which bear on their evaluation of Respondents' EMS and use of the
elements listed in Appendix I-1. The foregoing sentence is subject to applicable

Management Systems Analysis was conducted;

         (c) identification of audit team members;

         (d) summary of audit process, including identification of any obstacles
encountered;

         (e) discussion of Respondents' implementation of the elements listed on
Appendix I-1, including a discussion of any implementation of the elements
occurring during the audit process and the potential or actual EMS program gaps
relative to Appendix I-1;

         (f) if the Consultant Auditor concludes that Respondents have not
implemented or adequately implemented the elements listed on Appendix I-1,
recommendations of the Consultant Auditor for such implementation; and

         (g) the Consultant Auditor's certification that the Environmental
Management Systems Analysis was conducted in conformity to the Consent
Agreement.

         10. If the Consultant Auditor concludes that any deadline in this
Attachment or the Consent Agreement pertaining to the Environmental Management
Systems Analysis should be extended, it shall notify both Respondents and EPA.
EPA's decision whether to grant additional time shall be final and
non-reviewable.

         11. Within thirty (30) calendar days of receiving the final Audit
Report, Respondents shall incorporate all reasonable Consultant Auditor's
recommendations into their "Corporate Compliance Policies and Procedure Manual"
(the "Manual"). If Respondents conclude that implementation of a recommendation
would not be reasonable, they must notify EPA in writing, so that further
negotiations with EPA regarding the matter may occur. Respondents shall provide,
prior to its discussion with EPA regarding the recommendations of the Consultant
Auditor, a written explanation as to why they plan to implement the
recommendation(s) with modification or why they do not plan to implement the
recommendation (s). Upon incorporation of the Consultant Auditor's
recommendations into the Manual, Respondents shall use the updated Manual. Six
months thereafter, Respondents will, in consultation with the Consultant
Auditor, review their implementation of the Consultant Auditor's recommendations
and determine if further changes need to be made in their EMS. Respondents will
inform EPA and the Participating States of their findings and of any revisions
to the Manual.

         12. Until December 31, 2005, EPA and the Participating States may
review the Manual on request and, upon reasonable notice, confer with
Respondents about it and implementation of Respondents' EMS program.

                         ENVIRONMENTAL COMPLIANCE AUDIT

         This Attachment J sets forth the terms and provisions of the
"Environmental Compliance Audit" referred to in Paragraph 98 of the Consent
Agreement. The definitions in the Consent Agreement apply to this Attachment.
Additional definitions for this Attachment are set forth herein.

         EPA acknowledges that the deadlines set forth in this Attachment and
the Consent Agreement for this Environmental Compliance Audit are predicated
upon Respondents' obtaining Bankruptcy Court approval for the Consent Agreement
and retention of the Consultant Auditor (defined in paragraph 2 below) in early
September 2000. If Bankruptcy Court approval is delayed, EPA agrees that one or
more of the deadline(s) associated with this Environmental Compliance Audit may
need to be extended, and EPA agrees to consider the fact of delayed Bankruptcy
Court approval in good faith in determining whether to extend any deadline.
Respondents agree to exercise their best efforts to obtain final Bankruptcy
Court approval of the Consultant Auditor if they determine such approval is
necessary.

         1. EPA is requiring the Environmental Compliance Audit to determine and
ensure Respondents' compliance with the applicable provisions of RCRA and TSCA.
The Environmental Compliance Audit will cover the period January 1, 2000 through
the date the Consultant Auditor's investigation is complete.

         A. The Environmental Compliance Audit will occur at the following
facilities with respect to the requirements of TSCA:

         Tucker, Georgia
         Pecatonica, Illinois
         Kansas City, Missouri
         Twinsburg, Ohio
         Greenbrier, Tennessee
         Aragonite, Utah
         Deer Park, Texas

         B. The Environmental Compliance Audit will occur with respect to the
requirements of RCRA at the drum shredding operations at the following
facilities:

         Aragonite, Utah
         Deer Park, Texas
         Buttonwillow, California
         Westmorland, California
         New Castle, Kentucky
         Chattanooga, Tennessee


<PAGE>


The facilities listed in this paragraph are hereinafter referred to as the
"Audit Facilities."

        2. No later than September 1, 2000, Respondents shall provide to EPA in
writing (i) the name and address of the person or entity that it proposes to
conduct the Environmental Compliance Audit ("Consultant Auditor"); and (ii) the
Consultant Auditor's qualifications relevant to performing the Environmental
Compliance Audit.

        3. The Consultant Auditor may have no financial or other conflict of
interest that would prevent it from exercising independent judgment and
discipline analogous to that which a certified public accounting firm would be
expected to exercise in auditing a publicly-held corporation. If the Consultant
Auditor already is under contract to Respondents, Respondents must disclose this
to EPA. Additionally, Respondents shall disclose to EPA any long term or
significant contractual relationship it had with the Consultant Auditor since
January 1, 1998.

        4. After consulting with the Participating States, EPA will notify
Respondents whether EPA approves the retention of the proposed Consultant
Auditor. If EPA disapproves the proposed Consultant Auditor, Respondents must
propose another Consultant Auditor within fifteen (15) calendar days, and the
commencement and conclusion dates for the Environmental Compliance Audit set
forth in Paragraph 98 of the Consent Agreement will be deemed adjusted
accordingly.

        5. Thirty (30) calendar days after its retention, the Consultant Auditor
will submit a proposed work plan to EPA and the Participating States for the
Environmental Compliance Audit. The work plan will set forth the Consultant
Auditor's schedule for completion of the Environmental Compliance Audit,
including the dates of on-site audit activities. In connection with the work
plan, the Consultant Auditor will be available to meet in person with EPA and
Respondents to obtain background information useful to the conduct of the
Environmental Compliance Audit. EPA will, if it deems it necessary, provide a
list of key action items (i.e., those areas under the regulatory scheme that EPA
and the Participating States deem of concern) that need to be assessed under the
Environmental Compliance Audit. These action items will be incorporated into the
Consultant Auditor's work plan.

        6. After consulting with the Participating States, EPA will provide
comments on the work plan within ten (10) working days of receiving it.
Respondents also may comment on the work plan. The Consultant Auditor shall have
ten (10) working days to incorporate Respondents' and EPA's comments into the
work plan or explain in the work plan why the comments have not been
incorporated. If EPA is not satisfied with the Consultant Auditor's explanation
for the failure to incorporate EPA's comments, EPA will promptly notify the
Consulting Auditor and Respondents and will reserve all rights with respect to
whether the resulting Environmental Compliance Audit has satisfied Paragraph 98
of the Consent Agreement.

         7. Respondents will provide any documents that the Consultant Auditor
requests which bear on determining the Audit Facilities' compliance with TSCA or
RCRA, as the case may be, subject to applicable privileges, such as the
attorney/client privilege. Respondents also will

                                       2

<PAGE>


provide the Consultant  Auditor  physical access to pertinent  operations at the
Audit Facilities.

         8. The Consultant Auditor shall complete its investigation of the Audit
Facilities so that a written document setting forth the conclusions and
recommendations of the Consultant Auditor (the "Audit Report") in draft form can
be presented to EPA and the Participating States by April 15, 2001(1).
Respondents and EPA may provide comments to the Consultant Auditor on this draft
Audit Report, but must do so in a timely manner so that the Consultant Auditor
can provide a final Audit Report to Respondents, EPA and the Participating
States by May 15, 2001. A copy of the draft and final Audit Report will not be
released to the Participating States unless the Participating States agree to
the terms in paragraph 11 of this Attachment. The Consultant Auditor shall
incorporate Respondents' and EPA's comments in the final Audit Report or explain
in that Report why the comments have not been incorporated. If EPA is not
satisfied with Consultant Auditor's explanation for the failure to incorporate
EPA's comments, EPA will promptly notify the Consulting Auditor and Respondents
and will reserve all rights with respect to whether the resulting Environmental
Compliance Audit has satisfied Paragraph 98 of the Consent Agreement.

         9. The final Audit Report shall contain at least the following:

         A.  Audit scope, including time period;
         B. The dates on which the on-site portions of the Environmental
Compliance Audit were conducted;
         C.  Identification of audit team members;
         D. Identification of Respondents' personnel who observed the on-site
portions of the Environmental Compliance Audit;
         E. Summary of audit process, including identification of any obstacles
encountered;
         F. Identification of all non-compliance with TSCA or RCRA, as the case
may be, including the bases for that identification;
         G. If the Consultant Auditor concludes that the identified
non-compliance stems from management systems deficiencies, the identification of
such deficiencies;
         H. Identification of any such non-compliance that Respondents corrected
prior to release of the final Audit Report(2), a description of the corrective
measure and when it occurred; and
         I. The Consultant Auditor's certification that the Environmental
Compliance Audit was conducted in conformity to the Consent Agreement.

         10. If the Consultant Auditor concludes that any deadline in this
Attachment or the Consent Agreement pertaining to the Environmental Compliance
Audit should be extended, it

----------------
(1) Participating States do not receive a draft or final Audit Report regarding
the Audit Facilities set forth in Paragraph 1(A) of this Attachment.

(2) Noncompliance corrected by Respondents prior to the release of the final
Audit Report shall be subject to the statements regarding the imposition of a
civil penalty as set forth in Paragraph 11 of this Attachment.

                                       3
<PAGE>

shall  notify  both  Respondents  and  EPA.  EPA's  decision  whether  to  grant
additional time shall be final and non-reviewable.

         11. Within sixty days of receiving the final Audit Report, Respondents
shall correct or arrange for the correction of any noncompliance at the Audit
Facilities identified in the final Audit Report and address any management
systems deficiencies that the Audit Report has identified. During this period,
EPA and the Participating States that have agreed to be bound by this paragraph
will not initiate an enforcement action to penalize Respondents for the
identified noncompliance provided, however, that Respondents agree to toll any
applicable statutes of limitations. EPA and the Participating States reserve the
right to impose penalties at the conclusion of the correction period for any
noncompliance that has been identified in the Audit Report. The preceding
sentence specifying a correction period does not apply if EPA or the
Participating States have independent knowledge of the noncompliance.

         12. Nothing in this Attachment restricts EPA or the Participating
States from enforcing any Environmental Law against Respondents at the Audit
Facilities.

         13. Any submission to EPA (and the Participating States) shall not be
interpreted as a waiver or limitation of the EPA's or the United States (or the
Participating States) authority to enforce any federal, state or local statute
or regulation including permits.
