                       ESTABLISHMENT, PURPOSE AND OVERVIEW


1.1      ESTABLISHMENT OF THE PLAN

         The Board of Directors (the "Board") of Aqua-Chem,  Inc.  ("Aqua-Chem")
approved  the  new  Aqua-Chem,  Inc.  1998  Phantom  Stock  Plan  ("Plan")  as a
substitute for the previous Executive  Management  Incentive Plan ("EMIP") which
was terminated as of December 31, 1997.

1.2      PURPOSE OF THE PLAN

         The goal of the Plan is to provide certain senior level executives and
officers of Aqua-Chem selected by the Board to participate in the Plan
("Participants") with the opportunity to share in future increases in the value
of Aqua-Chem Common Stock without the necessity of using personal funds to
purchase stock. This goal is accomplished by awarding each Participant a
specified number of phantom shares ("Phantom Shares").

1.3      OVERVIEW OF THE PLAN

         The Plan provides minimum performance requirements, measured in terms
of earnings before interest, taxes, depreciation and amortization ("EBITDA"). If
these requirements are met, a Participant, who is employed by the Company on the
scheduled payment dates (subject to certain exceptions described below), will be
entitled to receive the value as of specified maturity dates of the Phantom
Shares initially awarded to the Participant (the "Maturity Value"). Maturity
Value will be equal to (i) the number of Phantom Shares initially awarded to the
Participant, multiplied by (ii) the value of a share of Aqua-Chem Common Stock
as determined by the formula set forth in Section 2.6 below.


                                   ARTICLE II
                              PHANTOM SHARE AWARDS


2.1      AWARD DATES

         On April 1 of each year ("Award Date"), commencing April 1, 1998, the
Board shall grant to each Participant entitled thereto, as determined by the
Board, awards of Phantom Shares ("Awards").

2.2      INITIAL AWARDS OF PHANTOM SHARES

         On the initial Award Date, April 1, 1998, each Participant in the Plan
will receive three separate awards of Awards, subject to the conditions and
requirements set forth below:

         -        The first Award ("1999 Award") will entitle the Participant to
                  receive the Maturity Value as of March 31, 1999 ("Maturity
                  Date").

         -        The second Award ("2000 Award") will entitle the Participant
                  to receive the Maturity Value as of March 31, 2000.

         -        The third Award ("2001 Award") will entitle the Participant to
                  receive the Maturity Value as of March 31, 2001.

2.3      FUTURE AWARDS

         The number of Phantom Shares to be included in future Awards, the dates
Awards will be paid out ("Payout Date") and the Budgeted EBITDA requirements
applicable thereto will be determined for each such future Award by the Board in
its discretion. Any future Awards will all have a Maturity Date ending on the
last day of the third fiscal year following the Award Date.

2.4      MINIMUM PERFORMANCE REQUIREMENTS

         The right of a Participant to receive the Maturity Value of the 1999
Award is contingent upon Aqua-Chem and its subsidiaries, on a consolidated
basis, achieving during the fiscal year beginning April 1, 1998 and ending March
31, 1999 "Actual EBITDA" equal to ninety percent (90%) or more of "Budgeted
EBITDA" (as these terms are defined below) for such fiscal year.

         The right of a Participant to receive the Maturity Value of the 2000
Award is contingent upon Aqua-Chem and its subsidiaries, on a consolidated
basis, during the fiscal year beginning April 1, 1999 and ending March 31, 2000)
achieving Actual EBITDA equal to eighty percent (80%) or more of the Budgeted
EBITDA for such fiscal year. The right of a Participant to receive the Maturity
Value of the 2001 Award is contingent upon Aqua-Chem and its subsidiaries on a
consolidated basis during the fiscal year beginning April 1, 2000 and ending
March 31, 2001) achieving Actual EBITDA equal to eighty percent (80%) or more of
the Budgeted EBITDA for such fiscal year.

         "Actual EBITDA" for any fiscal year shall mean earnings (with
appropriate accruals for Awards under the Phantom Stock Plan) before interest,
depreciation and amortization as set forth on the annual year end audited
consolidated balance sheet of Aqua-Chem with such adjustments, for

transactions not in the ordinary course of business or otherwise as the
Board, in its discretion, determines to be appropriate.  "Budgeted EBITDA" shall

                           March 31, 2000                     $22,909,000
                           March 31, 2001                     $28,678,000


2.5      PAYOUT OF AWARDS

                  (ii)     Two-thirds (2/3) of the Maturity Value of the 2000

                  (iii)    Two-thirds (2/3) of the Maturity Value of the 2001

         (b) DELAYED PAYOUT DATES. Payout Dates for any Award may be delayed, as
necessary, if the audited year-end financial statements of Aqua-Chem or any of

Maturity Value (as defined in Section 2.6 below) of such Award.

         (c) EFFECT OF DEATH, DISABILITY, RETIREMENT, TERMINATION. In order to
be entitled to receive any payment under the Plan, a Participant must be
employed by Aqua-Chem or its subsidiary on the Payout Date for such Award unless

         (i)      death;

         (ii)     disability (as defined in the Aqua-Chem long-term disability
                  insurance policy as in effect from time to time);

                                                                   EXHIBIT 10.12


         (iii)    retirement (either normal retirement, as defined in the
                  Aqua-Chem qualified retirement plan as in effect from time to
                  time or early retirement, with the prior written consent of
                  Aqua-Chem); or

         (iv)     termination by Aqua-Chem or any of its subsidiaries for
                  reasons other than "Cause" (Cause includes such acts as
                  violation of confidentiality or noncompete agreements; acts of
                  fraud, dishonesty, or gross misconduct; and such other acts
                  which are deemed by the Board to constitute a material breach
                  of employment terms).

In the event of a Participant's termination of employment in accordance with
Subsections (i)-(iv) of this Section 2.5(c), such Participant shall be entitled
(on such Payout Dates as are specified in Section 2.5 or in future Awards) to
payout of the prorated Maturity Value of each Award granted to such Participant,
determined by multiplying the Maturity Value of the Award by a fraction, the
numerator of which is the number of months in the fiscal year ending on the
Maturity Date of such Award in which the Participant was employed by Aqua-Chem
or its subsidiary (including the month of separation) and the denominator of
which is twelve. If a Participant is for any other reason not employed by
Aqua-Chem or a subsidiary on the Payout Date for any Award, any and all amounts
otherwise payable to the Participant under such Award shall be forfeited.

         (d) MINIMUM PAYOUT. In the event that for any Participant (i) the
amount (based upon performance for 1996 and 1997) that was scheduled to be paid
out at the end of the 1998 calendar year under the prior EMIP Plan is greater
than the amount that becomes payable to the Participant under the Plan on June
1, 1999 (i.e., two-thirds of the Maturity Value of the 1999 Award) then, in such
event the Participant shall, in lieu of the amount payable under the Plan, be
entitled to receive the amount that he or she would have received under the EMIP
Plan at the end of the 1998 calendar year and (ii) the amount (based upon
performance for 1997) that was scheduled to be paid out at the end of the 1999
calendar year under the prior EMIP Plan is greater than the amount that becomes
payable to the Participant under the Plan on June 1, 2000 (i.e., two-thirds of
the Maturity Value of the 2000 Award) then, in such event the Participant shall,
in lieu of the amount payable under the Plan, be entitled to receive the amount
that he or she would have received under the EMIP Plan at the end of the 1999
calendar year.

2.6      DETERMINATION OF MATURITY VALUE

         The "Maturity Value" of an Award shall mean an amount equal to (i) the
number of Phantom Shares included in the Award, multiplied by (ii) the "Per
Share Stock Value" as defined below.

         The "Per Share Stock Value" shall mean an amount, determined as of the
Maturity Date of an Award, equal to the following:

         (i)      six (6) times Actual EBITDA for the fiscal year ending on the 
                  Maturity Date;  plus


                                      -4-
   7

         (ii)     the excess, if any, of the book value of cash and marketable
                  securities as reflected on Aqua-Chem's fiscal year end audited
                  balance sheet as of the Maturity Date over Eight Million
                  Dollars ($8,000,000); minus

         (iii)    the sum of the following as reflected on Aqua-Chem's fiscal
                  year end audited balance sheet as of the Maturity Date:

                  (a)      the excess, if any, of amount of any indebtedness
                           pursuant to any short term or revolving credit
                           facility which is utilized to meet working capital
                           requirements over Eight Million Dollars ($8,000,000);
                           plus

                  (b)      the amount of all other indebtedness arising in
                           connection with borrowed funds, but excluding
                           accounts payable and accrued expenses; plus

                  (c)      the book value of the issued and outstanding Series
                           A, B and C Preferred Stock plus accrued dividends
                           thereon;

with the result so obtained, divided by

         (iv)     the number of shares of Aqua-Chem Common Stock outstanding or
                  reserved for issuance on the Valuation Date computed on a
                  fully-diluted basis, excluding the Phantom Shares awarded
                  under the Plan but including, without limitation, all shares
                  of Common Stock which may be issuable upon the exercise of any
                  and all stock options or warrants.

2.7      NON-TRANSFERABILITY OF AWARDS

         Participants may not assign Awards other than by will or descent,
except that Participants may designate a beneficiary ("Beneficiary") to receive
any amounts payable with respect to Awards upon the death of a Participant. A
Participant may from time to time revoke or change his Beneficiary without the
consent of any prior Beneficiary by filing a new designation with the Committee.
The last such designation received by the Committee shall be controlling;
provided, however, that no designation or change or revocation thereof, shall be
effective unless received by the Committee prior to the Participant's death, and
in no event shall any designation be effective as of a date prior to such
receipt. If no such Beneficiary designation is in effect at the time of the
Participant's death, or if no designated Beneficiary survives the Participant,
or if such designation conflicts with law, the Participant's estate acting
through his legal representative, shall be entitled to payout. If the Committee
is in doubt as to the right of any person to payout, the Committee may refuse to
payout such Award, without liability, until the Committee determines the person
entitled to payout. The person applying to the Committee for payout or the
Committee may apply to any court of appropriate jurisdiction and such
application shall be a complete discharge of the liability of the Committee
therefor.

3.1      AUTHORITY OF BOARD

         The Board, or any committee which the Board may appoint ("Committee",

also be deemed to be references to the Committee), shall have the sole and
exclusive right and authority to:

         (c)      make any and all modifications to the terms of the Plan that
                  the Board, in its sole discretion, deems to be appropriate in
                  the event that there should occur a stock split, stock
                  dividend, recapitalization or any other event, which in the
                  sole and exclusive opinion of the Board equitably requires
                  that a modification be made; and

         (d)      terminate the Plan and any Awards previously made pursuant to
                  the Plan; provided, however, that any amounts payable in the
                  future to Participants, pursuant to Awards previously made
                  which have reached their scheduled Maturity Date, shall be
                  paid out in accordance with the terms of the Plan.

Any determination made or action by the Board pursuant to the preceding

nor the Committee may delegate any of its responsibilities hereunder to any
person who is not both a "Non-Employee Director", as that term is defined in

3.3      LIABILITY; INDEMNIFICATION

         No member of the Board or the Committee, nor any person to whom
ministerial duties have been delegated, shall be personally liable for any
action, interpretation or determination made with respect to the Plan or Awards
made thereunder, and each member of the Board and Committee shall be fully 
indemnified, held harmless and protected by Aqua-Chem with respect to any

amended from time to time, or under any agreement between any such member and 
Aqua-Chem.

Board, are selected to be Participants. Phantom Shares are only a vehicle for
measuring the amount to be paid to each Participant in the Plan. The Plan does
not involve the actual ownership of any stock of Aqua-Chem and shall not confer

organization succeeding to all or substantially all of the assets and business
