                  Executive's employment is terminated by the Company for
                  reasons other than "Cause" (as hereinafter defined), then,

                  (3) Upon proper application by Executive and payment of the
                  employee portion of the premium, the Company shall furnish

                  (4) The Company shall continue to provide the Executive the
                  financial planning services which the Company was providing at

                  ("Retirement Plan") the Company shall pay the Executive the
                  lump sum actuarial equivalent of his accrued benefit under the
                  Retirement Plan, calculated using the same actuarial

   4


                  (2) Executive's disability or incapacity which extends for a
                  period of nine consecutive months and which renders Executive,
                  in the judgement of the Board, substantially unable to perform
                  the services for which he has been employed, or

                  (3) Executive's willful commission of misconduct which is
                  materially injurious to the Company, monetarily or otherwise;

                  paragraph 11 of this Agreement by Executive during his
                  employment shall constitute willful misconduct without further

                  appear before the Board at such meeting and defend himself,
                  that Executive has committed fraud, embezzlement, theft, or
                  misappropriation against or from the Company; or

                  Agreement.

                           For purposes of this paragraph 9, no act or failure
                  to act shall be considered "willful" unless done or omitted to
                  be done without good faith and without a reasonable belief
                  that the act or omission was in the best interest of ESCO.

                  C.       TERMINATION BY THE EXECUTIVE FOR GOOD REASON.

                           If, during the term of this Agreement, but under
                  circumstances not described in paragraph 8, above, the
                  Executive terminates his employment for "Good Reason" (as
                  hereinafter defined), then, in addition to his regular salary
                  and benefits through the date of termination, provided the

                  Reason" shall mean the occurrence of any one or more of the

                  Company promptly after receipt of written notice thereof given
                  by the Executive and other than a failure to comply with
                  paragraphs 3 through 7 hereof inclusive solely by reason of a
                  reduction in compensation or benefits that applies to all
                  Senior Management employees;

                  Company. The Executive specifically agrees that the one (1)
                  year period is reasonable.

                           If the Executive fails to comply with any of his
                  undertakings hereunder, except as otherwise required by law no
                  further payments or contractual benefits shall be provided to
                  or in respect of the Executive by the Company pursuant to this
                  Agreement or otherwise. The provisions of paragraph 12 shall
                  not apply to any alleged violations of this paragraph, and the
                  Company shall be entitled to obtain temporary and permanent
                  injunctive relief, as well as damages, before any court of
                  competent jurisdiction in St. Louis County for any violation
                  of the provisions of this paragraph by Executive.

         12.      ENFORCEMENT - ARBITRATION. Except as provided in paragraph 11,
                  any controversy or claim arising out of or relating to the
                  application, interpretation or enforcement of this Agreement,
                  and any claim of every nature and description by the Executive
                  against the Company and/or any of its parent, subsidiary,
                  affiliated entities, corporation, partnerships, and their
                  members, officers, directors,

                  managers, partners, employees, fiduciaries, administrators,
                  agents or attorneys or by the Company against the Executive
                  which cannot be settled by negotiation of the parties,
                  including, but not limited to, any and all claims arising
                  subsequent to the date of this Agreement under each of the
                  statutes, common law, contractual and other authorities
                  enumerated in Exhibit A, attached hereto and made a part
                  hereof, shall be settled by final and binding arbitration
                  administered by the American Arbitration Association
                  ("Association") under its Employment Dispute Resolution Rules
                  (as amended and effective on November 1, 1993, subject to the
                  then-current fees) and judgement on the award rendered by the
                  arbitration may be entered in any court having jurisdiction
                  thereof subject to the following provisions, except as
                  otherwise mutually agreed by the parties with respect to a
                  particular dispute or provision at the time:

                  a. If the parties cannot agree upon an arbitrator, a
                  seven-person panel shall be submitted to the parties by the
                  Association. If there is a non-selection of the first such
                  panel, the Association shall submit a second seven-person
                  panel to the parties. If there is still a non-selection, the
                  Association shall then appoint a single arbitrator in
                  accordance with its rules subject to each party's objection
                  for cause, and if the claim involves an alleged statutory
                  violation, the arbitrator shall be an attorney.

                  b. The initiating party shall pay one-half of the
                  administrative fee(s) and the defending party shall pay
                  one-half of such fee(s).

                  c. Each party may take two (2) depositions and the deposition
                  of any expert as a matter or right, and the parties may engage
                  in additional prehearing discovery only for good cause shown
                  to the arbitrator. Any documents to be introduced in evidence
                  and any documents subpoenaed, as well as a list of all
                  witnesses to be called, shall be submitted to the other party
                  at least thirty (30) days prior to the initial hearing date
                  unless the arbitrator otherwise orders.

                  d. Any hearing shall be recorded by a professional reporter.
                  Each party shall have at least thirty (30) days to submit
                  post-hearing briefs, and the hearing shall not be deemed
                  closed until after the date for submission of such briefs. Any
                  extensions are subject to the control of the arbitrator.

                  e. The arbitration provisions of this Agreement shall not
                  apply to any claims by the Executive for benefits if they are
                  not payable by the Company or if there is another final and
                  binding dispute resolution in the plan, for Workers'
                  Compensation or unemployment compensation or as excluded in
                  paragraph 11, hereof.

                  f. Notice of any claim must be given by the aggrieved party in
                  writing to the other party within nine (9) months of the date
                  the aggrieved party first has knowledge of the event, or
                  should have knowledge of the event giving rise to the

                                       7

   8


                  claim; otherwise, the claim shall be void and deemed waived
                  even if there is a federal or state statute of limitations
                  which would have given more time to pursue the claim. The
                  written notice shall identify and describe the nature of each
                  claim asserted, the statutes, regulation, Agreement provision
                  or other authority on which it is based and a brief statement
                  of the facts supporting such claim. The notice shall be sent
                  by certified mail to the last address supplied in writing by
                  the other party.

                  g. The arbitrator acting under this Agreement may award
                  damages, and any other relief (s)he deems just and proper
                  which is provided in any statute applicable to the claim,
                  including attorney's fees, arbitration costs and
                  administrative fees, including but not limited to those
                  previously paid by the parties under 12(b). The decision of
                  the arbitrator shall be final and binding on all parties and
                  anyone claiming by or through them. The remedy provided in
                  this paragraph 12 shall be the exclusive remedy for all
                  unsettled disputes between the parties except those
                  specifically excepted in subparagraph (e) above.

         13.      If ESCO is the Employer, any agreement, representation, or
                  other action of the "Employer" herein shall be ESCO's own
                  obligation, enforceable by Executive against ESCO. If a
                  subsidiary of ESCO is the Employer, then ESCO agrees to cause
                  the Employer to honor any such agreement, representation, or
                  other action of the "Employer" herein; the obligation of
                  Executive, however, shall remain ESCO's and shall be
                  enforceable by Executive only against ESCO or, in accordance
                  with section 14 below, ESCO's successor or assignee.

         14.      SUCCESSORS AND ASSIGNS. This Agreement shall inure to the
                  benefit of the Executive and shall be binding upon the
                  Company, and its successors and assigns.

         15.      AMENDMENT. This Agreement may be amended by mutual written
                  agreement of the parties. The parties also recognize the
                  possibility of circumstances arising in which this Agreement
                  would be terminated by mutual written agreement without
                  terminating Executive's employment.

         16.      GOVERNING LAW. This Agreement shall be construed and
                  interpreted in accordance with the laws of the State of
                  Missouri, excluding Missouri's choice of law rules, and except
                  to the extent governed by federal law.


         17.      CONSULTANT SERVICES. The Company may ask the Executive to
                  serve as a Consultant to the Company from time to time after
                  the Executive's employment ceases. For one year after the
                  Executive's employment terminates, if the Executive is
                  receiving the compensation and benefits outlined in paragraph
                  8, 9(a) or 9(c), then the Executive agrees to perform up to 80
                  hours of consulting without additional compensation other than
                  as provided herein and reimbursement of any reasonable
                  out-of-pocket expenses necessarily required or approved in
                  advance.
