     supersede the Executive's  right to receive any benefit earned prior to the
     Executive's  retirement,  or any  provision  of  this  Agreement  expressly
     providing a benefit to the Executive.

         2.       Transition Period.

          days comprising the Transition Period divided by 365.

               2.5 Long Term Incentive  Compensation.  All  performance  shares,
          stock options or  restricted  stock awards  previously  granted to the
          Executive pursuant to the Company's incentive compensation plans shall
          fully vest and be  distributed  in  accordance  with the terms of such
          applicable  plans,  except that any  performance  share and restricted

          terms of such coverage.

               3. Consulting  Agreement.  On or before the Retirement  Date, the
          Executive  and the  Company  will enter into a  Consulting  Agreement,

          Date for a fee of $300,000 payable bi-weekly pursuant to the Company's
          payroll  practices (the "Consulting  Fee").  The Consulting  Agreement
          shall  contain  such  reasonable  and  customary   provisions   deemed
          acceptable  by  the  Company  in  its  discretion,  including  without

          way of illustration  only,  Title VII of the Civil Rights Act of 1964,

          damages  released and  discharged  by this Section  include all those,
          known or  unknown,  accrued or not yet fully in being,  which exist in

          timely elect to receive after his retirement

               4.2 Knowing and Voluntary.  Executive  specifically  acknowledges
          that the waiver of all of his claims is knowing and voluntary and that
          this waiver is a part of this  Agreement  which has been  written in a
          manner  calculated  to be,  and  which  is,  understood  by him and he
          intends  to  be  bound  by  this  entire  Agreement.  He  specifically
          acknowledges   waiving  and   releasing   any  claims  under  the  Age

          execute  this  Agreement:  (a)  that  he  relied  entirely  on his own
          judgment and that of any legal counsel or advisor he may have employed
          (and not on ESCO) in assessing the extent and merit of any claims, the
          likelihood,  if any,  of  prevailing  on those  claims,  the amount of
          damages,  if any,  which he would receive in the event any such claims
          were successfully established and the tax treatment of the amount paid
          hereunder; (b) that no facts, evidence, event or transaction currently
          unknown to him, but which may  hereinafter  become known to him, shall
          affect in any way or manner  the  final  unconditional  nature of this
          Agreement;  (c) that his  execution of this  Agreement is a completely
          voluntary act on his part; (d) that he  understands  the terms of this
          Agreement;  (e) that he has been  advised by ESCO to consult  with his
          legal  counsel and has been  provided  with adequate time to do so, at
          his own expense,  prior to executing this  Agreement;  (f) that he has
          been advised that this offer  remains open for a period of  twenty-one
          (21) days from the date he receives a copy of this  Agreement  so that
          he may fully  consider this  Agreement  prior to executing it; and (g)
          that if he does not execute and return this  Agreement  to ESCO within
          such period,  ESCO will consider his  non-action a refusal to agree to
          the terms of this Agreement,  and the offer and terms extended by this
          Agreement are revoked effective as of that date and time.

               4.4  Revocation  and Effective  Date. The parties agree that this

          consultant,  and Executive  expressly  acknowledges the termination of
          the Employment Agreement pursuant to the terms of this Agreement. This
          Agreement  does not terminate or supersede  any agreement  between the
          Executive  and  the  Company  relating  to  the  Executive's  conduct,
          behavior,   incentive  compensation  or  fringe  benefits,  except  as

               5.7  Arbitration.  Any  controversy  or claim  arising  out of or
          relating  to  this  Agreement  or  any  other  agreement  contemplated
          hereunder, or the interpretation or breach hereof or thereof, shall be
          submitted  to binding  arbitration  conducted in the City or County of
          St.Louis,  Missouri,  in accordance with the then current  Employment
          Dispute  Resolution  Rules of the  American  Arbitration  Association,
          unless  otherwise  agreed.  The parties  shall  select one  arbitrator
          familiar with a background in arbitrating  employment disputes. If the
          parties  are  unable to agree on the  selection  of an  arbitrator  to
          resolve the dispute  within  fifteen  (15) days of either party giving
          the other  party  notice of its intent to invoke  this  Section,  then
          either  party  may  make  a  request  of  the   American   Arbitration
          Association for a list of qualified  potential  arbitrators from which
          the  parties  shall  select  an  arbitrator  in  accordance  with  the
          Employment  Dispute  Resolution  Rules  of  the  American  Arbitration
          Association.  If no arbitrator is thus  selected  within  fifteen (15)
          days after such list is  submitted  to the  parties,  either party may
          request the American Arbitration  Association to select an arbitrator.
          Subject  to the  following  sentence,  all  expenses  and  fees of the
          arbitrator  and any other  expenses of the  arbitration  will be borne
          equally by parties  unless the  arbitrator in the award  assesses such
          expenses  against one of the parties or allocates  such expenses other
          than  equally  between  the  parties.  Each  party  will  bear its own
          attorneys'  fees and expenses,  unless the  arbitrator  finds that the
          claim or defense  of any party was  frivolous  or lacked a  reasonable
          basis in fact or law, in which case the  arbitrator may assess against
          such party all or any part of the attorneys'  fees and expenses of the
          other party.  The  determination of such arbitrator shall be final and
          binding upon the parties and judgment may be entered  thereupon in any
          court having jurisdiction  thereof. The provisions of this Section 5.7
          shall  not  apply to the  enforcement  of any  covenants  relating  to
          non-competition,  non-solicitation,  confidentiality  or disparagement
          contained in this  Agreement or any related  agreement.  Further,  the
          provisions  of this  Section  5.7 shall  not  limit the  rights of the
          Company to obtain  injunctive  relief  enjoining  the  Executive  from
          taking  actions or  threatening  to take an action in violation of the
          terms of this Agreement or any related agreement.

          IN  WITNESS  WHEREOF,   the  foregoing  Agreement  has  been  executed
          effective as of August 5, 2002.

THIS CONTRACT CONTAINS A BINDING ARBITRATION  PROVISION WHICH MAY BE ENFORCED BY
THE PARTIES.
