CONSULTING AGREEMENT

         AGREEMENT, made and entered into as of the 18th day of October, 1999
(the "Effective Date"), by and among, Aqua-Chem, Inc., a Delaware company (the
"Company"), J. Miller Management, Inc., a Michigan corporation ("JMM") and
Jeffrey A. Miller ("Miller").

         WHEREAS, Miller has served as President and Chief Executive Officer of
the Company and, simultaneous with the execution of this Agreement, is resigning
from such positions; and

         WHEREAS, the Board of Directors desires Miller to provide ongoing
consulting services to the Company and Miller desires to do so through his
independent consulting firm, JMM.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements hereinafter set forth, the Company, Miller and JMM hereby agree as
follows:

         1. CONSULTING SERVICES. Following the Effective Date and continuing
until the earlier of (i) October 17, 2001, or (ii) the sale of substantially all
of the assets or stock of the Company or the adoption of a plan of providing for
the complete liquidation of the Company (hereinafter respectively referred to as
a "Disposition" and the "Consulting Period"), JMM shall provide consulting
services to the Company on an as needed basis. Such consulting services shall be
performed by Miller personally and provided at mutually agreeable times and
places so as to not unreasonably interfere with other JMM engagements. JMM shall
be responsible for all expenses incurred in providing consulting services except
travel expenses incurred at the request of the Company, which shall be
reimbursed in accordance with the Company's policies, applicable to all
employees, as in effect from time to time. After the Effective Date the Company
shall no longer provide JMM or Miller with an office, but shall continue to
provide E-mail and voice mail support. As part of the consulting arrangement,
JMM and Miller agree to cooperate with the Company to transfer Miller's
responsibilities and duties as president and CEO to his successor. Miller's
duties as a consultant shall not preclude his providing services to others,
provided that the performance of such services does not violate the restrictions
hereinafter set forth in this Agreement.

         2. CONSULTING FEES AND RELATED MATTERS. Subject to Miller not
exercising his revocation right with respect to the Agreement and Release dated
October 29, 1999, the Company agrees to pay the consulting fees hereinafter set
forth. During the period from October 18, 1999, through October 17, 2000, the
Company will pay JMM a consulting fee at the annual rate of $498,750 per year.
Except as set forth in the preceding sentence, this first year consulting fee
shall not be subject to any future Board approvals or contingencies and shall be
paid in full irrespective of a Disposition. From October 18, 2000, until the
earlier of (1) October 17, 2001, or (2) the date of a Disposition, the Company
will pay JMM a consulting fee at the annual rate of $200,000 per year. In the
event of a Disposition after October 17, 2000, the consulting fee shall

                                       6

<PAGE>   7

be pro-rated to the date of Disposition. Said consulting fees shall be paid in
bi-weekly installments (pro-rated for the first and final month). It is hereby
acknowledged and agreed by all parties that from and after the Effective Date
Miller is an employee of JMM and not an employee of the Company and JMM shall be
solely responsible for any and all taxes on any nature whatsoever relating to
the consulting fees. Miller and JMM hereby jointly and severally agree to
forever indemnify and hold harmless the Company and its affiliates from any and
all liabilities (including reasonable attorney's fees) for any tax, interest
and/or penalties in any manner relating or attributable to the consulting fees.

         3. RESTRICTIONS. (a) JMM and Miller acknowledge and agree that the
Company's business is by its nature international, the Company's business and
customer contacts have been established and maintained at great expense, Miller,
by virtue of his position with the Company, has and will continue to be privy to
the Company's most confidential business plans and strategies which, without the
restrictions hereinafter set forth, would enable Miller and/or JMM to compete
unfairly with the Company and, accordingly, such restrictions are reasonable and
necessary to protect the legitimate interests of the Company. Miller and JMM
hereby jointly and severally covenant and agree that neither Miller nor JMM will
at any time subsequent to the date hereof, reveal, divulge, or make known to any
Person any Confidential Information (as hereinafter defined) made known to
Miller or JMM or of which Miller or JMM become aware, regardless of whether
developed, prepared, devised or otherwise created in whole or in part by the
efforts of Miller or JMM and except to the extent so authorized in writing by
the Company in order to carry out the terms of this Agreement or except as
required by law. For purposes of this Agreement, the term "Confidential
Information" shall mean (i) any technical, scientific or engineering information
relating to the Company's products and/or services, (ii) information relating to
any customer of the Company, including without limitation, the names, addresses,
telephone numbers and sales records of, or pertaining to any such customer, and
(iii) price lists, methods of operation, financial data, business and/or
strategic plans and/or other information pertaining to the Company which the
Company has treated as confidential or protected as a trade secret.
Notwithstanding anything contained herein to the contrary, Confidential
Information as used herein shall not include that which (i) is or becomes
generally available to the public other than as a result of a disclosure by
Miller or JMM or its affiliates or representatives, (ii) was available to Miller
or JMM prior to its disclosure to Miller or JMM by the Company or its
representatives, or (iii) becomes available to Miller or JMM from a source other
than the Company or its representatives, provided that such source is not bound
by a confidentiality agreement with the Company or its representatives.

                  (b) Miller and JMM hereby jointly and severally covenant and
agree that at no time during the Consulting Period, will either Miller or JMM
directly or indirectly in any capacity whatsoever (whether as an employee,
officer, director, consultant, partner, member, joint venturer, agent,
representative or otherwise) provide service, advice or assistance of any nature
to, or acquire an ownership interest in (or acquire the right to acquire an
ownership interest in a Competing Business (as hereinafter defined). A
"Competing Business" shall mean and be limited to any business, regardless of
the form of organization, which (1) is engaged in

                                       7

<PAGE>   8

the design, manufacture and/or sale of products which are similar in design or
function to or otherwise compete with the products which were under design by
the Company or included in the Company's product lines during the Consulting
Period (hereinafter referred to as "Competing Products") and which also (ii)
sells, attempts to sell or markets such Competing Products within the United
States and/or any foreign country within which, during the Consulting Period the
Company sold any of its products (or was a party to an executory contract for
the sale of any of its products), attempted to sell, or marketed any of its
products other than by means of general advertising. Notwithstanding the
preceding, neither Miller nor JMM shall be prohibited from (1) acquiring less
than five percent (5%) of the stock of any publicly traded company; or (2)
providing services to a company that, among it businesses, is engaged in a
Competing Business, provided that Miller is not personally directly or
indirectly involved in any capacity whatsoever in such Competing Business.

                  (c) During the Consulting Period, neither Miller nor JMM shall
directly or indirectly, on behalf of either of them or any other person, entity,
or business, employ or engage the services of any person employed by the Company
or any agent who represents the Company during the Consulting Period, or
otherwise encourage or entice any such person to terminate or diminish their
relationship with the Company.

                  (d) Miller and JMM hereby acknowledge and agree (i) Miller's
education and experience are such that the foregoing restrictions will not
unduly interfere with his ability to earn a livelihood, (ii) the Company would
suffer irreparable harm in the event of a violation of such restrictions, and
(iii) accordingly, in addition to any other remedies available to it, the
Company shall be entitled to injunctive relief, without the posting of bond or
other collateral. All costs, including reasonable attorneys' fees, incurred in
enforcing this provision shall be reimbursed to the prevailing party.

                  (e) If any court shall determine that the duration or any
other aspect of the Restrictions is unenforceable, it is the intention of the
parties that the Restrictions shall not thereby be terminated, but shall be
deemed amended to the extent required to render them valid and enforceable, such
amendment to apply only with respect to the operation of this paragraph in the
jurisdiction of the court which has made such adjudication.

                  (f) This Agreement shall be deemed to be severable, and any
part hereof which may be held invalid by a court of competent jurisdiction shall
be deemed to be excluded from this Agreement, and the remaining parts shall
remain in full force and effect; provided, however, that should any aspect of
the Restrictions be held to be unenforceable as a result of the challenging of
same by Miller or JMM, then Miller and JMM shall immediately repay to the
Company any consulting fees paid to JMM, and the Company shall have no further
obligation whatsoever to make any payments pursuant to the terms of this
Agreement.

                                       8

<PAGE>   9

                  (g) The parties acknowledge and agree that breach of the
Restrictions would cause irreparable damage to the Company and that monetary
damages alone would not provide the Company with an adequate remedy. Therefore,
if any controversy arises concerning the Restrictions, such Restrictions shall
be specifically enforced by injunction, without any requirement for the posting
of any bond or other collateral. Such remedy, however, shall be cumulative and
non-exclusive, and the Company shall be entitled to any other remedy provided by
law, including monetary damages.

                  (h) The parties agree that nothing in this Agreement should be
construed to limit or negate the common law of torts or trade secrets where it
provides the parties with broader protection than that provided herein.

         4. MISCELLANEOUS. This Agreement shall be governed by and construed
under the laws of the State of Wisconsin, and any dispute arising out of or
relating to this Agreement shall be brought in a court of competent jurisdiction
in Milwaukee County, Wisconsin. The headings of the sections contained in this
Agreement are for convenience only and shall not be deemed to control or affect
the meaning or construction of any provision of this Agreement. This Agreement
may be signed in counterparts, with the same effect as if the signatures were
upon the same instrument. This Agreement shall be binding upon and inure to the
benefit of Miller's personal or legal representatives and heirs and shall be
binding upon and inure to the benefit of the Company's successors and assigns.
This Agreement shall not be deemed or construed to have been modified, amended,
rescinded, canceled or waived, in whole or in part, except by written instrument
signed by the parties hereto. This Agreement supersedes all other agreements or
understandings (whether oral or written) between Miller and the Company with
respect to the subject matter herein and constitutes the entire agreement of the
parties with respect to the same.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first set forth above.

Mr. Robert D. Endacott
1352 Shire Circle
Inverness, IL 60067

Dear Bob,

         At the outset, the Aqua-Chem Board of Directors has requested that I
convey to you its appreciation for all of the valuable contributions that you
have made to the Company over the past several years. Aqua-Chem's decision to
terminate the services that you have been providing to Aqua-Chem as Vice
Chairman and an employee and the consulting services that CMR Partners has been
providing to Aqua-Chem is not caused by any dissatisfaction with such services
but, rather, is the result of other changes within the Company eliminating the
need for the services.

         The balance of this letter will confirm the arrangements that we have
discussed in connection with the termination of services. If you are in
agreement with the arrangements set forth herein, please so indicate by signing
and returning the enclosed copy of this letter and the attached General Release.
The agreed upon arrangements are as follows:

         -     You hereby resign, effective immediately, as an employee and Vice
               Chairman of Aqua-Chem, Inc.

         -     You and Aqua-Chem, Inc. hereby agree that, except for obligations
               not to compete and to maintain confidentiality, the Agreement
               among Aqua-Chem, Inc., CMR Partners and you entered into as of
               June 1, 1999 and signed on August 23, 1999 as it relates to your
               employment is hereby terminated.

         -     CMR Partners and Aqua-Chem, Inc. hereby agree that, except for
               the obligations of the parties under sections 4.2, 6.1, 6.2 and
               6.3 which shall continue in force, the Agreement between
               Aqua-Chem, Inc. dated September 26, 1997 as subsequently amended
               on February 18, 1998, November 13, 1998 and as of June 1, 1999
