RECITALS.

 1.   An agreement (the "Amoco Tax Agreement") was entered into as of the 23rd
      day of February, 1995 by and among Amoco Corporation, an Indiana

 2.   Pursuant to the Amoco Tax Agreement, Walter, Walter Holdings, Walter
      Congo, Nuevo, Nuevo Holdings and Nuevo Congo agreed to jointly and
      severally indemnify and hold harmless APC, its Affiliates and their
      respective directors, officers and employees from and against any and all
      Taxes, tax credits utilized, interest, penalties, cost of enforcement,
      and reasonable attorneys fees incurred in defending against any claim for
      Taxes, interest, penalties, or additional income or enforcement of the
      indemnification, if any, arising out of, or based upon, or with respect
      to any failure by Walter, Walter Holdings, Walter Congo, Nuevo, Nuevo
      Holdings or Nuevo Congo to comply with each and every obligation and
      covenant of the Amoco Tax Agreement (generally relating to the avoidance
      of a "Triggering Event" within the meaning of Treasury Regulation Section
      1.1503-2).

      indemnify and hold harmless APC, its Affiliates and their respective
      directors, officers and employees from and against any and all Taxes, tax

      respect to any failure by CMS, Enterprises, Nomeco, Walter, Walter
      Holdings, or Walter Congo, to comply with each and every obligation and
      covenant of the CMS Tax Agreement (generally relating to the avoidance of
      a "Triggering Event" within the meaning of Treasury Regulation Section
      1.1503-2).

 5.   An agreement (the "Guarantee Agreement") was entered into as of the 17th
      day of January, 1995 by and between Nomeco and APC whereby Nomeco agreed
      to guarantee certain of Walter's potential liabilities, including certain
      obligations of Walter under the Amoco Tax Agreement.

 6.   The Amoco Tax Agreement was entered into as part of a transaction by
      which Walter Congo, a Congolese affiliate of APC, was acquired by an
      affiliate of Walter and Nuevo Congo, a Congolese affiliate of APC, was
      acquired by an affiliate of Nuevo (collectively, the "Initial
      Acquisitions").  The CMS Tax Agreement was entered into as part of a
      transaction by which, among other matters, CMS acquired Walter and then
      contributed the stock of Walter to Enterprises, followed by a
      contribution by Enterprises of the Walter stock to Nomeco (collectively
      the "Walter Acquisition").

 7.   As a part of (a) the Initial Acquisitions and (b) the Walter Acquisition,
      Amoco, Walter, CMS and Nuevo (and certain of their respective affiliates)
      requested certain private letter rulings from the Internal Revenue
      Service dealing, generally, with whether (i) the tax losses resulting
      from the operations of APC's Congolese affiliates (and utilized by Amoco
      to reduce its United States federal income tax liability) constituted
      "dual consolidated losses" within the meaning of Section 1503(d) of the
      Internal Revenue Code of 1986, as amended (the "Code") and Treasury
      Regulation Section 1.1503-2(c)(5), and (ii) the various transactions
      relating to the Initial Acquisitions and the Walter Acquisition
      constituted "Triggering Events" within the meaning of Treasury Regulation
      Section 1.1503-2.  Pursuant to the requests for private letter rulings
      described in the preceding sentence, Amoco, Walter, Nuevo, CMS and
      certain former shareholders of Walter submitted forms of closing
      agreements and protective closing agreements (collectively, the "Closing
      Agreements") for execution by the Internal Revenue Service and the
      appropriate taxpayers relating to the treatment of the Congolese losses
      as a result of the Initial Acquisitions and the transactions entered into
      pursuant to the Walter Acquisition, as well as certain agreements with
      respect to the utilization and treatment of such losses in the future.
      Although the Closing Agreements have not yet been entered into by the
      Internal Revenue Service or the appropriate taxpayers, it is contemplated
      that such agreements (subject to possible modification) will be entered
      into in the near future.

 8.   The parties believe that it is appropriate for (a) CMS to indemnify
      Nomeco, Walter, Walter Congo and Walter Holdings against certain
      liabilities that such indemnified party may incur in the future under the
      Amoco Tax Agreement, the CMS Tax Agreement, the Guarantee Agreement or
      the Closing Agreements and for (b) Nomeco and Walter to indemnify CMS and
      Enterprises against certain liabilities that CMS or Enterprises may incur
      in the future under the CMS Tax Agreement or the Closing Agreements.


NOW, THEREFORE, in consideration of the premises and the respective covenants,
agreements and conditions contained herein, the parties hereby agree as
follows:

 1.   INDEMNITY

      A.   If, as a result of (1) any event that occurs prior to the effective
           date of the initial consummation of the Nomeco initial public
           offering (the "Effective Date"), (2) an act or omission of CMS or
           any entity that controls, is controlled by, or is under


                                      2


   3

           common control with, CMS (other than Nomeco or any of its
           subsidiaries) taken on or after the Effective Date, or (3) an act or
           omission of Nomeco or any of its subsidiaries taken on or after the
           Effective Date with Consent (as defined below), a liability arises
           or is asserted to arise under the CMS Tax Agreement, the Amoco Tax
           Agreement or the Guarantee Agreement, then CMS agrees to indemnify
           and hold harmless Nomeco, Walter, Walter Holdings and/or Walter
           Congo, as they may be, against (1) any and all amounts which they
           are required to pay under the CMS Tax Agreement; (2) any amounts
           which Walter, Walter Holdings or Walter Congo are required to pay
           under the Amoco Tax Agreement not related to dual consolidated
           losses of Nuevo, Nuevo Holdings or Nuevo Congo; (3) any amounts
           which Nomeco is required to pay under the Guarantee Agreement not
           related to dual consolidated losses of Nuevo, Nuevo Holdings or
           Nuevo Congo; (4) any and all costs of enforcement of this indemnity
           (including reasonable attorney fees); and (5) all reasonable
           attorneys fees incurred in defending against any liability under the
           Amoco Tax Agreement, the Guarantee Agreement or the CMS Tax
           Agreement (including defending against any such liability by
           defending against any claim for taxes asserted by the Internal
           Revenue Service but not including defending against any liability
           related to dual consolidated losses of Nuevo, Nuevo Holdings or
           Nuevo Congo).   For purposes of this Agreement, Consent means
           approval of an action by the Board of Directors of Nomeco, which
           approval includes the affirmative vote of a majority of those
           members of the Board of Directors of Nomeco who are employees of CMS
           or any of its subsidiaries (other than Nomeco or any of its
           subsidiaries).

      B.   If as a result of (1) any event that occurs prior to the Effective
           Date or (2) an act or omission of CMS or any entity that controls,
           is controlled by, or is under common control with, CMS (other than
           Nomeco or any of its subsidiaries) taken on or after the Effective
           Date or (3) an act or omission of Nomeco or any of its subsidiaries
           taken on or after the Effective Date with Consent, a liability
           arises or is asserted to arise under any of the Closing Agreements,
           then CMS agrees to indemnify and hold harmless Nomeco, Walter,
           Walter Holdings and Walter Congo against (1) any and all amounts
           payable by such indemnified party pursuant to the terms of the
           Closing Agreements; (2) any and all costs of enforcement of this
           indemnity (including reasonable attorneys fees); and (3) all
           reasonable attorneys fees incurred in defending against any claim
           for payments pursuant to the terms of the Closing Agreements.

      C.   If, as a result of an act or omission of Nomeco or any of its
           subsidiaries taken on or after the Effective Date without Consent, a
           liability arises or is asserted to arise under the CMS Tax
           Agreement, then Nomeco agrees to indemnify and hold harmless CMS and
           Enterprises against (1) any and all amounts which they are required
           to pay under the CMS Tax Agreement; (2) all costs of enforcement of
           this indemnity (including reasonable attorney fees); and (3) all
           reasonable attorneys fees incurred in defending against any
           liability under the CMS Tax Agreement (including defending against
           any such liability by defending against any claim for taxes asserted
           by the Internal Revenue Service).

      D.   If, as a result of an act or omission of Nomeco or any of its
           subsidiaries taken on or after the Effective Date without Consent, a
           liability arises or is asserted to arise



                                      3

   4

           under any of the Closing Agreements, then Nomeco agrees to indemnify
           and hold harmless CMS and Enterprises against (1) taxes and all
           amounts payable by CMS or Enterprises pursuant to the terms of the
           Closing Agreements; (2) all costs of enforcement of this indemnity
           (including reasonable attorneys fees); and (3) all reasonable
           attorneys fees incurred in defending against any claim for payments
           pursuant to the terms of the Closing Agreements.

      E.   All indemnity payments hereunder shall be made on an "after-tax
           basis," and therefore shall be in an amount which, after subtraction
           of the amount of all federal, state and foreign taxes payable by the
           recipient thereof as a result of the receipt or accrual of such
           payment (the "Gross-Up Amount"), and after taking into account the
           reduction in federal, state and foreign taxes payable by the
           recipient as a result of allowable deductions for the payment or
           accrual of items included in the amount of the indemnity payable
           hereunder, shall be sufficient as of the date of payment to
           compensate the recipient for such indemnified event.

           The determination of the Gross-Up Amount payable with respect to an
           indemnified event shall be made by the recipient in the exercise of
           its reasonable judgment.  Such recipient shall furnish the payor
           with a notice (the "Gross-Up Notice") setting forth the Gross-Up
           Amount so payable and, in reasonable detail, the computation of such
           amount.  If reasonably requested by the payor in writing within 10
           days of receipt of such Notice, such computation shall be subject to
           verification at the expense of the payor by the firm of independent
           certified public accountants which regularly reviews the recipient's
           financial statements, provided, however that the cost of such
           verification shall be at the cost of the recipient if such
           accountants determine that the Gross-Up Amount payable is less than
           90% of the amount set forth in the Gross-Up Notice.  Such
           verification which is made by such accountants in accordance
           herewith shall be conclusive absent manifest error.

 2.   RIGHTS OF INDEMNIFYING PARTY

      Upon the agreement to pay CMS or Enterprises in full any indemnified
      amounts hereunder, the indemnified party agrees to assign to Nomeco any
      and all rights which such party possesses as an indemnifying party (but
      not as an indemnified party) under the CMS Tax Agreement or as a payor
      under the Closing Agreements.  To the extent that Amoco fails to
      recognize the assignment of any such rights under the CMS Tax Agreement,
      CMS agrees to exercise any such rights on behalf of, and as directed by,
      Nomeco.  Upon the agreement to pay Nomeco, Walter, Walter Holdings or
      Walter Congo in full any indemnified amounts hereunder, the indemnified
      party agrees to assign to CMS any and all rights which such party
      possesses as an indemnifying party (but not as an indemnified party)
      under the Amoco Tax Agreement, the CMS Tax Agreement or the Guarantee
      Agreement (as the case may be) or as a payor under the Closing
      Agreements.

 3.   NOTICES

      A.   CMS agrees to furnish to Nomeco promptly a copy of any notice
           received or delivered by CMS or any of its Affiliates under the CMS
           Tax Agreement or the Closing Agreements.  Nomeco and Walter agree to

           copy of any notice received or delivered by Nomeco or Walter or any
           of their Affiliates under the Amoco Tax Agreement, the CMS Tax
           Agreement or the Closing Agreements.  Nomeco and Walter further
           agree to comply with the provisions of the first paragraph of
           Article 7 A of the CMS Tax Agreement as if Nomeco and Walter were
           referenced therein together with Amoco and CMS.  CMS further agrees
           to comply with the provisions of the first paragraph of Article 7 A
           of the Amoco Tax Agreement as if CMS were referenced therein
           together with the other parties thereto.

           hand to the party for which intended, (ii) by registered or

 4.   CONTEST

      A.   Upon receipt by Nomeco of a written notice from CMS or Enterprises
           of a claim that an amount may be payable by Nomeco to CMS or
           Enterprises pursuant to Sections 1.C. or 1.D. hereof (hereafter
           called a "Claim Notice"), Nomeco may request, in writing, that CMS
           or Enterprises contest (or use its best efforts to cause Amoco or
           Amoco's affiliates to contest) the adjustment which resulted in such
           Claim Notice.  CMS shall (and shall use its best efforts to cause
           Amoco or Amoco's affiliates to) consult in good faith with Nomeco
           with respect to the prosecution and possible settlement of such
           contest, including the opportunity to be present at and participate
           in all conferences with the Internal Revenue Service with respect to
           the adjustment giving rise to the Claim Notice.  In connection with
           any such contest, CMS shall provide (and use its best efforts to
           cause Amoco or Amoco's affiliates to provide) Nomeco with copies of
           all documents, pleadings,



                                      5

   6

           briefs and other documents to be submitted to the Internal Revenue
           Service or any other party sufficiently prior to such submission so
           as to permit Nomeco and its counsel with an opportunity to comment
           thereon and shall consider Nomeco's comments in good faith.

      B.   Neither CMS nor Enterprises is required to contest (or cause Amoco
           or Amoco's affiliate to contest) such adjustment until CMS shall
           have received from Nomeco, at Nomeco's expense, a written opinion of
           independent tax counsel reasonably satisfactory to CMS to the effect
           that there is substantial authority in law and fact for contesting
           such adjustment and Nomeco shall have agreed to pay, and shall pay,
           CMS on demand all reasonable out-of-pocket costs and expenses which
           CMS may incur in connection with contesting such adjustment,
           including without limitation, reasonable fees for attorneys and
           accountants.

      C.   If Nomeco shall have requested CMS to contest (or cause Amoco or
           Amoco's affiliates to contest) such adjustment as above provided in
           subsections A or B and shall have duly complied with all the terms
           of this Section, Nomeco's liabilities for indemnification under this
           Agreement with respect to such adjustment (but not for the costs and
           expenses incurred in connection with the contest of such adjustment)
           shall be deferred until a Final Determination of the liability of
           CMS or Enterprises has occurred.  (For purposes of this Agreement,
           the term "Final Determination" shall be (x) a decision, judgment,
           decree or other order has become final (i.e., when all allowable
           appeals conducted in accordance with this Section have been
           exhausted by either party to the action) or in any case where
           judicial review shall at the time be unavailable, a decision,
           judgment, decree or other order of an administrative, official or
           agency of competent jurisdiction, which decision, judgment, decree
           or other order has become final (i.e., all administrative appeals
           have been exhausted by either party to the action), (y) a closing
           agreement entered into under Section 7121 of the Code or any other
           settlement agreement entered into in connection with an
           administrative or judicial proceeding, in accordance with this
           Section 4 or (z) the expiration of the time for instituting a claim
           for refund, or if such claim were filled, the expiration of the time
           for instituting suit with respect thereto.)  At such time, Nomeco
           shall become obligated for the payment of any indemnification
           hereunder resulting from the outcome of such contest and such amount
           shall be paid within 30 days after such Final Determination.

           Notwithstanding anything herein to the contrary, neither CMS nor
           Enterprises (or their representatives or affiliates) shall enter
           into a closing agreement under Section 7121 of the Code or any other
           settlement agreement in connection with an administrative or
           judicial proceeding with respect to any matter for which it is
           entitled to be indemnified hereunder, unless it first obtains the
           written consent of Nomeco to such closing agreement or settlement
           agreement or expressly waives its right to receive indemnification
           hereunder with respect to such matter.  The failure of CMS or
           Enterprises to obtain the consent described in the preceding
           sentence shall constitute a waiver by each of CMS and Enterprises of
           its right to receive indemnification hereunder with respect to such
           matter.

      D.   Upon receipt by CMS of a written notice from Nomeco or its
           subsidiaries of a claim that an amount may be payable by CMS to
           Nomeco or its subsidiaries


                                      6


   7

           pursuant to Sections 1.A. or 1.B. hereof, CMS shall have rights
           reciprocal to those of Nomeco described in paragraphs A., B. and C.
           of this Section 4.

 5.   DEFINITIONS

      All capitalized terms in this Agreement not otherwise defined herein
      shall have the meanings as set forth in the CMS Tax Agreement.

 6.   SUCCESSORS AND ASSIGNS

      This Agreement shall be binding upon and inure to the benefit of the
      parties and their respective permitted successors and assigns.  No party
      to this Agreement shall be relieved of its obligations hereunder, by
      assignment or otherwise, without the prior written consent of the other
      parties hereto.

 7.   GOVERNING LAW

      This Agreement shall be governed by the laws of Michigan excluding any
      choice of law provisions which would require the application of the law
      of any other jurisdiction.

 8.   FURTHER ASSURANCES

      The parties hereto hereby agree to execute all such further instruments
      and documents, and to take all such other actions, as may be reasonable
