ITEM 1. BUSINESS.

     The Company is the world's leading manufacturer of commercial and
industrial packaged boilers, burners, related equipment and aftermarket parts.
The Company believes that in the U.S. market for each of its three principal
boiler product lines it enjoys the #1 or #2 market position. In addition,
management believes that the Company has the largest installed base of packaged
boilers in the world (estimated at over 80,000 boilers), which facilitates the
Company's sale of higher margin aftermarket parts. Management attributes the
Company's leading market positions to its extensive global distribution network,
well-recognized Cleaver-Brooks and Nebraska Boiler brand names, and its
reputation for providing high-quality, energy-efficient, low-emission boilers
with a demonstrated record of safety and durability.

     The Company is also a world leader in the design and production of water
purification and treatment products and systems sold under the Aqua-Chem brand
name for selected commercial, government, military, and industrial applications.

HISTORY

     Founded in 1929 as the John C. Cleaver Company and later known as
Cleaver-Brooks, the Company began as an innovative manufacturer of small,
portable boilers that were sold packaged and fully assembled. Cleaver-Brooks,
which continues to operate as a division of the Company, eventually became, and
for over 20 years has been, the world's largest manufacturer of commercial and
industrial packaged boilers, burners, related boiler-room equipment and
aftermarket parts. The Company increased its presence in the boiler market with
the acquisition of substantially all of the assets of National Dynamics
Corporation ("NDC") on June 23, 1998 (the "NDC Acquisition") and now conducts
NDC's former operations through its National Dynamics Division ("National
Dynamics").

     Cleaver-Brooks began manufacturing steam-powered water purification stills
in the early 1940's in response to a military request for a portable system
capable of purifying unfit drinking water. This business, which currently
operates as the Company's Water Technologies Division ("Water Technologies"),
has become a leading manufacturer of innovative water treatment products and
systems for a variety of commercial, government, military and industrial
applications.

     On July 31, 1997, Aqua-Chem management, led by Chairman and CEO Jeffrey A.
Miller, and Whitney Equity Partners, L.P. (a fund managed by J. H. Whitney &
Co.) acquired Aqua-Chem (the "Management Buy-Out") from its former owners.

BOILER MARKET

     Boilers burn a variety of fuels to provide: (i) hot water for residential,
commercial, institutional and industrial uses; (ii) hot water or low-pressure
steam for use in circulatory heating systems; and (iii) process steam for a wide
variety of industrial applications and to drive turbines for the generation of
electricity. The boiler market can generally be segmented according to boiler
capacity and end use. Residential boilers are the smallest, followed by
commercial boilers, industrial boilers, and utility boilers, which are the
largest. Boiler capacities generally are measured in British Thermal Units
("BTU") or boiler horsepower ("BHP") output for smaller boilers, and in pounds
of steam per hour ("PPH") for larger boilers. One BHP equals 33,472 BTU per
hour, which in turn produces approximately 28 to 35 PPH, depending on pressure
and feedwater temperature.

     Commercial packaged boilers generally range from 15 BHP (or approximately
500,000 BTU per hour) up to 250 BHP and are used in apartment buildings, hotels,
office buildings, schools, hospitals, and government buildings primarily to
provide hot water or low-pressure steam for circulatory heating systems, and, to
a lesser extent, for potable hot water. Commercial packaged boilers range in
price between $15,000 and $50,000.

                                        1
<PAGE>   4

     Industrial packaged boilers, with capacities from approximately 250 BHP to
over 250,000 PPH, are larger, more powerful and more expensive than commercial
packaged boilers, and are generally used to provide high-pressure process steam
for industrial applications, such as driving steam-operated presses, mill
equipment or machine tools, sterilizing equipment and products, and processing
chemicals, foods, beverages, and other products. Industrial packaged boilers are
used in a broad range of industries including paper, chemicals, electronics,
pharmaceutical, textiles, automotive, and heavy machinery. Industrial packaged
boilers range in price between $50,000 and $1 million.

     Based on industry sources, the annual worldwide market for packaged,
commercial and industrial boilers of all types is estimated to be in excess of
$1 billion, of which approximately $400 million is attributable to the North
American commercial and industrial boiler market.

CLEAVER-BROOKS DIVISION

     The Company's Cleaver-Brooks Division ("Cleaver-Brooks") is the world's
largest manufacturer of commercial and industrial packaged boilers. It has an
estimated installed base of approximately 80,000 boilers that remain in use and
believes it has the #1 or #2 market position in each of its principal product
lines. The Division's products include firetube and watertube boilers, burners,
and combustion and emission controls, boiler room accessories, and aftermarket
parts. Management believes that Cleaver-Brooks' reputation for providing
high-quality, energy-efficient, low-emission packaged boilers and ancillary
equipment with a demonstrated record of safety and durability often enables it
to command a premium price for its products from its diverse customer base.

  Products

     Cleaver-Brooks manufactures two types of packaged boilers -- firetube and
watertube -- for commercial and industrial applications. Most Cleaver-Brooks
packaged boilers can operate on multiple fuel options using both natural gas and
fuel oil. Cleaver-Brooks primarily manufactures "packaged" boilers, which are
shipped fully assembled and require minimum on-site installation, and also
manufactures a limited number of boilers that are designed to be "field-erected"
at the customer's facility. The high-quality boilers manufactured by
Cleaver-Brooks generally have a useful life of 20 years or more, depending upon
use and maintenance.

     Firetube Boilers. Firetube packaged boilers heat water or produce steam by
directing hot gas from the combustion process through tubes which are submerged
in a chamber of water inside the boiler. Heat is transferred from the hot gas in
the tube through the tube walls to the water.

     Cleaver-Brooks offers the industry's broadest line of firetube packaged
boilers, which are generally used in low and high pressure industrial
applications, and to produce heat and hot water for large commercial and
institutional buildings. Cleaver-Brooks firetube packaged boilers range in
capacity from 15 to 800 BHP. Although each Cleaver-Brooks firetube boiler is
manufactured to specific customer requirements, each is based on relatively
standardized pressure vessel sizes and other basic components. The prices of
Cleaver-Brooks firetube packaged boilers range from approximately $25,000 to
$150,000. Firetube packaged boilers represented approximately $66 million, or
47%, of Cleaver-Brooks' net sales for the twelve months ended March 31, 1999.

     Cleaver-Brooks firetube packaged boilers are highly regarded for their
quality, efficiency, safety, design simplicity, and ease of operation and
maintenance, as well as their long product life and low emission levels. High
efficiency is often the primary criterion in selecting a boiler as a $50,000
boiler system could consume over $150,000 per year in fuel. Therefore a slight
increase in boiler efficiency can translate into substantial annual savings.
Cleaver-Brooks packaged boilers are designed to operate efficiently to reduce
customers' fuel costs. They include what Aqua-Chem believes to be the world's
highest efficiency "four-pass" design and maintain high gas velocity which
provides maximum heat transfer. They also utilize a single tube sheet design
that maintains consistent temperatures for maximum operating life. Aqua-Chem
believes that these factors provide it with a competitive advantage in the
firetube boiler market.

                                        2

     Watertube Boilers. Watertube boilers produce hot water or steam by
directing water through tubes installed in a chamber filled with hot gas from
the combustion process. This fundamental difference between the firetube and
watertube process allows watertube boilers to be designed with greater capacity
and makes watertube boilers more suitable for certain large, multi-step
industrial applications than firetube boilers. Cleaver-Brooks produces watertube
packaged boilers in a range of models and capacities. Like its firetube packaged
boilers, Cleaver-Brooks watertube packaged boilers are manufactured for maximum
efficiency and ease of maintenance and are purchased by both industrial and
commercial end-users.

     Cleaver-Brooks commercial watertube packaged boilers range in capacity from
15 to 250 BHP, which is comparable to its smaller capacity firetube packaged
boilers, and include flexible watertube packaged boilers designed to simplify
installation, maintenance and tube replacement. The Division's flexible
watertube packaged boilers minimize potential thermalshock damage due to
temperature fluctuation, an especially important consideration with hot water
applications.

     Cleaver-Brooks only manufactures industrial watertube packaged boilers of
the "D" design (so named because the watertubes inside the boiler are shaped in
the configuration of the letter "D"), which is preferred by manufacturing
customers for most industrial applications. Cleaver-Brooks industrial watertube
packaged boilers range in capacity from 10,000 to 150,000 PPH (the approximate
equivalent of 1,400 to 4,000 BHP).

     Cleaver-Brooks watertube packaged boilers range in price from approximately
$150,000 to $1,000,000. Watertube boilers represented approximately $18 million,
or 13% of the Division's net sales for the twelve months ended March 31, 1999.

     Burners. Cleaver-Brooks is a leading supplier of highly-engineered, single
and multi-fuel engineered burners. These burners are installed as original
equipment on certain Cleaver-Brooks product lines, as a retrofit to existing
boilers where an upgraded or new burner is required, or, on new boilers
manufactured by competitors, under the Industrial Combustion brand name.
Cleaver-Brooks manufactures a broad range of burners that give customers the
flexibility to burn most liquid and gaseous fuels in use today. The Industrial
Combustion product line has an exceptionally strong market position
(approximately 86%) for heavy oil burners and is increasing its share of the gas
burner market. It was instrumental in originating the conversion burner business
and pioneered air atomizing and fuel metering technologies for using heavy fuel
oil.

     Boiler Room Accessories. Cleaver-Brooks also offers a wide range of boiler
room accessories, most of which are used to ensure that corrosive gases and
impurities found in water do not seriously affect boiler performance. This
equipment includes deaerators, water softeners, boiler feed water systems and
chemical feed systems. Other boiler room accessories regulate the flow of water
to and from the boiler.

     Aftermarket Parts. Taking advantage of its industry-leading installed base
of approximately 80,000 boilers, Cleaver-Brooks offers over 15,000 aftermarket
parts for its own and other manufacturers' boilers through its computerized
immediate access system. The immediate access system electronically links
Cleaver-Brooks' sales representatives and provides information regarding parts
availability, price lists and lead time. Cleaver-Brooks' sales representatives
and distributors stock Cleaver-Brooks parts inventory on a worldwide basis.
Aftermarket parts, which generally carry higher gross margins than new boilers,
represented approximately $33 million, or 24%, of Cleaver-Brooks' net sales for
the twelve months ended March 31, 1999. As part of several strategic
initiatives, management is emphasizing further penetration of the aftermarket
parts business through additional training and support of its extensive sales
representative network.

     Aftermarket products sold by Cleaver-Brooks include a wide range of
combustion and emission controls that generally enhance boiler performance or
safety, including low nitrous oxide ("NO(X)") emissions packages, conversion or
replacement burners, boiler control management systems, high turndown burners,
oxygen trim systems, and flame safeguard controls. For example, Cleaver-Brooks'
industry-leading low NO(X) emissions packages are guaranteed to as low as 20
parts per million ("ppm") of NO(X) levels and are extremely effective at
maintaining system efficiency levels. The majority of these parts are offered as
options to a boiler package.

     Although boilers generally have a useful life of up to 20 years, certain
boiler parts are subject to wear and require periodic replacement. These parts
consist primarily of combustion-oriented components such as
                                        3
<PAGE>   6

burners, burner-safety components, and emissions controls, but also include
certain water-bearing components. The need for aftermarket parts is a function
of the level of use to which a boiler is subjected. Boilers that "cycle" (turn
on and off) more frequently tend to wear more quickly. In addition, oil-burning
components tend to wear more quickly than natural gas-burning components.
Water-bearing components of a boiler can wear more quickly if the end-user does
not properly treat the water used in the boiler to reduce corrosive gases and
impurities that accumulate in untreated water.

     Commercial boiler wear can also be affected by cold weather when a boiler
is more likely to cycle more frequently. Many Cleaver-Brooks boilers are
equipped with multi-fuel options and can readily be switched by the end-user
from one fuel to the other. In many locations, boilers are required by law to
switch from burning natural gas to oil during extended periods of cold weather,
when demand for natural gas for residential and commercial forced-air heating is
high and available gas pressure is reduced. Industrial applications can also
involve high-cycle use, causing boilers to wear more quickly. Inadequate
maintenance practices can also affect boiler wear.

     In addition, the demand for aftermarket parts generally increases during
periods of economic difficulty when many businesses elect to defer the purchase
of new boilers in favor of repairing or retrofitting existing boilers. Aqua-Chem
believes that this phenomenon partially offsets the reduced demand for new
boilers during such periods.

  Commitment to Quality

     Cleaver-Brooks has received numerous industry and quality awards, including
the State of Wisconsin's 1995 Governor's New Product Award. Several of the
Division's products have been recognized by the Wisconsin Society of
Professional Engineers and the Model CB-LE was among a select group of winners
in a statewide competition which singled out new product innovations in large,
medium and small business segments. Additionally, with the introduction of its
low nitrous oxide (NO(X)) emissions product in the late 1980's, Aqua-Chem was
recognized by the South Coast Air Quality Management District as the first
boiler manufacturer to meet Southern California's stringent emissions standards,
as well as by the New York Bureau of Air Research.

  Sales, Marketing and Customers

     Cleaver-Brooks maintains strong relationships with its worldwide network of
sales and service representatives which management believes to be the most
extensive global distribution network for commercial and industrial boilers.
Cleaver-Brooks sells boilers through 50 domestic sales representatives located
throughout North America and 43 international sales representatives located in
Eastern Europe, Asia, Australia, Central and South America, and the Middle East.
These sales representatives have sold Cleaver-Brooks products for an average of
more than 25 years, and, pursuant to agreements with the Company, do not sell
products that compete directly with Cleaver-Brooks. No sales representative
accounted for more than approximately 5% of Cleaver-Brooks' net sales in the
twelve months ended March 31, 1999.

     Cleaver-Brooks' sales representatives primarily offer on-demand service and
parts support to consulting engineers, contractors and end-users, as well as
offering multi-year service contracts for boiler parts and accessories.
Additionally, as is customary in the industry, sales representatives provide
on-site start-up assistance and personnel training by factory-qualified
specialists and preventive maintenance programs as part of the range of services
available to keep boiler and pretreatment equipment operating at peak
performance.

     Cleaver-Brooks sells boilers to a diverse customer base in a broad range of
industries, with no significant customer concentration. Although Cleaver-Brooks'
customers vary from year to year, management believes that a substantial portion
of annual net sales are generally to repeat customers. Recent customers include
Ford, Cargill, Coca-Cola, Weyerhaeuser, Anheuser-Busch, Baxter Healthcare,
Ralston-Purina, Hewlett-Packard, Georgia Pacific, Chrysler-Jeep, Wrigley,
Sheraton, IBM, and NASA. For a further discussion of

sales by geographic area, see Note 14 to the Company's Consolidated Financial
Statements contained elsewhere herein.

  Raw Materials and Suppliers

     Cleaver-Brooks' primary raw materials include steel plate and coil steel.
The Division also purchases finished components for its products, such as
burners, tubes, controls, insulation, refractory materials, valves, gauges and
pumps. Cleaver-Brooks maintains one-year supply agreements with its steel
suppliers. These arrangements generally specify volume and price, but are
cancelable at any time by either party. For raw materials not covered by supply
agreements, Cleaver-Brooks generally chooses a particular supplier based on
market conditions, availability and pricing. Cleaver-Brooks works closely with
its major suppliers and is not dependent on any single supplier for any of its
raw material or component needs. Cleaver-Brooks is currently implementing new
purchasing procedures to reduce material costs, including consolidation of its
suppliers.

  Manufacturing

     Cleaver-Brooks operates through five manufacturing facilities located in
Stratford, Ontario, Canada; Thomasville, Georgia; Monroe, Wisconsin; Mexico
City, Mexico and Greenville, Mississippi (however, the Company is in the process
of closing its Greenville facility and transfering production to certain other
facilities and expects to complete this process by July, 1999). Additionally,
Cleaver-Brooks conducts applied engineering and product development activities
at a Milwaukee, Wisconsin location, which is shared with Water Technologies. See
"Properties and Employees."

     The Company has intensified its efforts to develop world-class
manufacturing facilities. Beginning in 1995, Aqua-Chem closed its Lebanon,
Pennsylvania facility, and consolidated its large firetube boiler production in
its Thomasville facility, and its smaller firetube boiler production in its
Stratford facility. These consolidations reduced labor and overhead costs by up
to one-third and took advantage of certain economies of scale in each facility.
In addition, the Company has been engaged in a program to improve its
manufacturing processes by adopting cellular manufacturing techniques,
just-in-time inventory controls and demand flow processing. These initiatives
have minimized scrap, identified manufacturing inefficiencies, significantly
reduced manufacturing cycle times and have already improved manufacturing
efficiency and inventory management at the Thomasville facility. Aqua-Chem
expects to implement similar cost reduction initiatives and manufacturing
improvements at its other facilities. Aqua-Chem has also established an internal
manufacturing council to address ongoing process improvements, share best
practices and instill a broad base of manufacturing expertise throughout the
organization. Additionally, in 1998, the Company decided to close its
Greenville, Mississippi manufacturing facility and relocate the manufacturing
operations currently located there to other Company facilities, including the
Lincoln, Nebraska facility acquired from NDC as part of the NDC Acquisition (the
"1998 Restructuring").

NATIONAL DYNAMICS DIVISION

     On June 23, 1998, Aqua-Chem aquired substantially all the assets of NDC.
The acquisition was accounted for using the purchase method of accounting.

  Products

     National Dynamics primarily designs and manufactures industrial watertube
packaged boilers, waste heat recovery systems and related accessories, as well
as a variety of standard and customized fabricated steel components, such as
ductwork and stacks, which are insourced for use in National Dynamics' products
and produced on a contract basis for other waste heat recovery system
manufacturers. Since the date of Acquisition, National Dynamics' net sales of
industrial watertube boilers and waste heat recovery systems, including related
accessories and components, represented approximately 93% of NDC's net sales.

     Industrial Watertube Boilers. National Dynamics produces shop-assembled
industrial watertube packaged boilers, components and other boiler accessories
under the Nebraska Boiler brand-name, chiefly for industrial and institutional
applications. The Nebraska Boiler product line consists primarily of industrial
                                        5
<PAGE>   8

watertube packaged boilers with larger capacities than those manufactured by
Cleaver-Brooks. Although National Dynamics manufactures industrial watertube
packaged boilers with capacities as low as 7,000 PPH, its primary focus is on
large industrial watertube packaged boilers that range in capacity from 100,000
to 250,000 PPH. In contrast, Cleaver-Brooks focuses on commercial and industrial
watertube packaged boilers with capacities under 100,000 PPH. The Nebraska
Boiler product line also includes industrial watertube packaged boilers that are
capable of producing steam at much higher temperatures and pressures than those
manufactured by Cleaver-Brooks. For the twelve months ended March 31, 1999
National Dynamics manufactured 60 industrial watertube boilers, which typically
ranged in price from approximately $150,000 to $1 million each.

     National Dynamics' primary unit is the "D" design watertube boiler, which
accounted for approximately 86% of National Dynamics' boiler sales since the
date of the NDC Acquisition. Nebraska Boiler industrial watertube packaged
boilers generally utilize the "membrane" tube design, in contrast to
Cleaver-Brooks boilers, which utilize the "tangent" tube design, each of which
is preferred by certain end users for various reasons. National Dynamics is also
one of the few boiler manufacturers that produces "O" and "A" design boilers in
addition to the "D" design. Although the "D" design is preferred for most
industrial applications, the symmetrically designed "O" and "A" boilers are more
readily transportable and better suited for certain uses. "O" design boilers in
particular are compact, fully assembled, easily transported by truck, and for
these reasons are considered ideal for use as "rental" boilers (boilers
installed temporarily to provide supplemental, backup or replacement service).
"A" design boilers typically are designed to have greater capacity than the "O"
or "D" designs and can be designed to burn a variety of alternative fuels (such
as coal, wood and saw dust). "O" and "A" design boilers accounted for
approximately 3% and 11%, respectively, of National Dynamics' boiler sales since
the date of Acquisition.

     National Dynamics also manufactures industrial watertube boiler components
and accessories, such as ducts, stacks, superheaters (an integral unit in the
boiler that heats the steam produced by the boiler to temperatures in excess of
750 degreesF for particular industrial applications) and economizers (an
integral or add-on unit that captures the heated air and flue gases vented from
the boiler's combustion chamber and uses them to preheat water entering the
boiler to conserve energy).

     Waste Heat Recovery Systems. National Dynamics designs and produces a
variety of packaged, modular and field-erected waste heat recovery systems under
the Energy Recovery International or "ERI" brand-name. The general principle
behind these systems is that the waste heat generated by a turbine or industrial
process can be recaptured and directed into a pressure vessel (resembling a
burnerless boiler) to generate hot water or steam, which can in turn be used to
drive a turbine to generate electricity (a process referred to as
"co-generation") or for other industrial applications. Co-generated electric
power may be used internally; however, if it is generated at levels in excess of
internal need, which is often the case, the excess electricity is generally sold
to the local power company, which has been made possible through the
deregulation of the domestic electrical power industry over the last few years.
For certain applications, waste heat recovery systems can also be designed to
operate with a supplemental heat source, such as a duct burner, that raises the
temperature and pressure to levels comparable with conventional boilers.

     NDC's sales of ERI products grew rapidly in the last few years and the
Company expects that such growth will continue due to increased demand for
energy efficient and environmentally conscious power projects, as well as
increased deregulation. Waste heat recovery systems are increasingly popular
because they provide an alternative source of power at significantly reduced
fuel cost.

     National Dynamics offers complete system design and service, based on the
customer's specific needs and requirements. In particular, waste heat recovery
systems are generally custom-designed for integration with the individual
customer's facility and equipment at the time of construction. For the year
ended March 31, 1999, National Dynamics manufactured 24 waste heat recovery
systems.

  Sales, Marketing and Customers

     National Dynamics markets its products primarily on the basis of quality,
dependability and custom engineering, which is complemented by the longstanding
working relationships NDC developed with
                                        6
<PAGE>   9

customers and premier engineering firms. National Dynamics products are marketed
worldwide through its 37 sales representatives and distributors, most of whom
sell both Nebraska Boiler and ERI products. Since the date of the NDC
Acquisition, one customer, Solar Turbines, accounted for approximately 19% of
National Dynamics' net sales. National Dynamics now utilizes Cleaver-Brooks'
international sales and marketing organization and representatives to market its
products internationally.

     National Dynamics sells its products to a diverse customer base in a broad
range of industries, with no significant customer concentration other than
indicated in the preceding paragraph. Recent customers included Bristol-Myers,
Goodyear, Dupont, Conoco, General Mills, Mitsubishi, Chevron, Exxon, Southern
Company and 3M.

  Raw Materials and Suppliers

     National Dynamics' primary raw material is steel, and it also purchases
finished components for its products, such as burners, tubes, controls,
insulation, refractory materials, valves, gauges and pumps. National Dynamics is
not dependent on any single supplier for any of its raw material or component
needs.

  Manufacturing

     National Dynamics operates three manufacturing facilities, two of which are
located in Lincoln, Nebraska and one of which is located in Gonzales, Texas. See
"Properties and Employees." National Dynamics has recently begun a program to
improve its manufacturing processes through the adoption of cellular
manufacturing techniques, just-in-time inventory controls and demand flow
processing. These initiatives are expected to minimize scrap, identify
manufacturing inefficiencies, significantly reduce manufacturing cycle times and
improve manufacturing efficiency and inventory management.

WATER TECHNOLOGIES DIVISION

     With over 50 years of experience, Water Technologies is a world leader in
the design and production of water purification and treatment products, systems,
aftermarket parts and service for selected commercial, government, military and
industrial applications. Water Technologies, which markets and sells its
products under the Aqua-Chem brand name, has two product categories: (i)
Freshwater and Military Products, which consist of products with relatively
standard components and configurations that are generally sold to customers in
the military, bottled water and pharmaceutical markets; and (ii) Seawater and
Industrial Systems, which consist primarily of large, highly engineered projects
and products that generally are sold to customers in markets for seawater
desalination and industrial evaporation processes.

  Products and Services

     Water Technologies manufactures products that utilize evaporation,
filtration and concentration technologies to create purified water for use in a
variety of applications. Water Technologies' primary products are thermal
distillation units, which convert seawater or contaminated fresh water into
clean water for drinking and manufacturing processes by passing feedwater over a
heated surface to create steam that is then condensed as distillate. Water
Technologies also offers reverse osmosis units, which pressurize contaminated
fresh or salt water to force it through a semipermeable membrane to produce
drinking water.

     Freshwater and Military Products. Freshwater and Military Products are
primarily pre-engineered water purification and treatment products and systems
for the bottled water and pharmaceutical industries and for the military. Water
Technologies also provides services and replacement parts for its Freshwater and
Military Products. Most Freshwater and Military Products are various types of
thermal distillation units, including an all-electric thermal distillation unit
that is installed on all U.S. Navy Trident submarines. Aqua-Chem believes that
every U.S. aircraft carrier and nuclear submarine utilizes Water Technologies
products to purify water for use by onboard personnel. Water Technologies also
manufactures a reverse osmosis unit marketed under the "ROWPU" (Reverse Osmosis
Water Purification Unit) name that is sold primarily to the U.S. military.
Freshwater and Military Products also include heat exchangers, which are used by
food, chemical and other industries to cool liquids. For example, the U.S. Navy
uses Water Technologies' heat
                                        7
<PAGE>   10

exchangers for seawater cooling of nuclear reactor waste water and feedwater
preheating in steam propulsion plants of nuclear aircraft carriers. Freshwater
and Military water purification units and heat exchangers generally sell for
between $100,000 and $500,000.

     Although individual units may be adapted to meet unique customer
specifications, Water Technologies manufactures all Freshwater and Military
Products to basic design parameters at its Knoxville, Tennessee facility.
Freshwater and Military Products are shipped from the Knoxville facility to the
customer as fully-manufactured systems that require a minimum number of piping
and electrical connections for installation. Once installed, the unit is ready
for operation.

     Seawater and Industrial Systems. Seawater and Industrial Systems are highly
engineered systems for land-based and offshore desalination and manufacturing
process plants. Water Technologies utilizes a number of thermal distillation
technologies to meet the specific needs of its Seawater and Industrial Systems
customers. Water Technologies offers both single effect systems, which are
low-cost and simple to operate, and multi-effect systems, which conserve energy
by linking two, three or more evaporators in series and, as a result, are more
popular for industrial applications. For example, Water Technologies has
installed a 10 million gallon per day seawater desalination system which
produces the entire fresh water supply for the Caribbean island of Aruba.
Seawater and Industrial Systems include thermal distillation units used by the
pulp and paper industry to concentrate heavy scaling sulfite pulping liquors.
Water Technologies also offers reverse osmosis units for industrial
applications.

     Many Seawater and Industrial Systems component parts are fabricated,
assembled and hydro-tested at the Knoxville facility prior to shipment to the
customer's job site, where they are assembled into a field erected plant.
Seawater and Industrial Systems are highly project oriented, may take from 10 to
14 months to complete, and are contracted on a fixed-price basis, typically
ranging between $1 million and $10 million in installed value.

  Sales, Marketing and Customers

     Water Technologies utilizes a network of over 40 representatives,
distributors and licensees worldwide to sell and market its Freshwater and
Military Products. Sales representatives are compensated on a commission-only
basis, while distributors typically make a profit margin on the purchase and
resale of Water Technologies parts. Due to the unique engineering considerations
and the magnitude of the projects, most Seawater and Industrial Systems are sold
by Water Technologies directly to end-users.

     For the year ended March 31, 1999, Water Technologies had approximately 345
customers worldwide, with no one customer representing more than 11% of its
gross sales. Water Technologies' leading customers generally vary from year to
year, due in part to the project-oriented nature of many of its Seawater and
Industrial Systems. Recent customers include Arvind Mills, the Aruba Water and
Energy Authority, and Newport News Shipbuilding. International customers
represented approximately 50% of Water Technologies' sales over the last three
years, with revenues generated from over 35 countries. Payment terms on
international sales are typically denominated in U.S. dollars and satisfied via
letters of credit.

     Typically, over half of Water Technologies' annual revenue is based upon
fixed-priced, long-term contracts. Generally, the term of the contract for
Freshwater and Military Products extends from the order date through shipment,
which usually ranges from 4 to 12 months. A start-up or test period may follow
shipment and last for 1 to 3 months. Customers are generally billed at the time
of shipment. Contract terms for Seawater and Industrial Systems may vary between
10 and 14 months. Seawater and Industrial Systems are contracted on a
fixed-priced basis, and customers are billed for work performed according to a
pre-arranged schedule detailed in the sales contract. For a further discussion
of sales by geographic area, see Note 14 to the Company's Consolidated Financial
Statements contained elsewhere herein.

  Product Service and Support

     Water Technologies supports its products with a staff of engineers and
service specialists who provide parts, service, technical training, service
publications, overhaul and repair for customers around the world. For

                                        8
<PAGE>   11

instance, Water Technologies provides qualified technical training anywhere in
the world through a team of training specialists who work closely with customers
to develop productive and dependable operators for all equipment.

     When service is needed, Water Technologies dispatches a qualified service
representative who assesses the customer's system and its repair requirements.
To meet customer needs quickly, Water Technologies distributors maintain
authorized parts and service centers across the continental United States, as
well as service centers in Alaska, Canada, South America, Northern Europe,
Southeast Asia, the Middle East and India.

  Raw Materials and Suppliers

     Water Technologies utilizes a wide variety of raw materials in the
construction of its products, including copper-nickel, alloys, stainless steel,
electrical control systems and a number of plastic and metal component parts.
Water Technologies maintains relationships with a select group of suppliers to
leverage its purchasing power and may enter into purchasing agreements to ensure
a reliable source of materials. Water Technologies has never experienced a
significant shortage of raw materials.

  Manufacturing

     Water Technologies' primary production facility is located in Knoxville,
Tennessee. The Knoxville plant, an ISO 9001 certified facility, provides
fabrication, machining, welding and assembly work for the production of both
Freshwater and Military Products and the component parts of Seawater and
Industrial Systems. Units are tested at the Knoxville plant prior to shipment to
the customer's site for installation. The Division is currently implementing
cellular manufacturing techniques, just-in-time inventory controls and
demand-flow processing to improve manufacturing efficiency and reduce production
costs.

     The Seawater and Industrial Systems business also utilizes subcontract
manufacturers in connection with international contracts when Aqua-Chem believes
that doing so provides a competitive advantage. To implement this international
subcontracting strategy, Water Technologies employs pre-qualified subcontractors
and project managers who are responsible for ensuring that quality, schedule and
other specifications of its Seawater and Industrial Systems contracts are met.
These project managers are supported by engineers who specialize in the
erection, commissioning, performance testing and overall service and
troubleshooting of the systems.

     Water Technologies shares an applied engineering and product development
facility with Cleaver-Brooks for evaluating the practical application of
evaporator technology on a broad range of processing needs. This capability is
an important part of Water Technologies' operations, enabling it to test the
performance and cost effectiveness of the systems it offers.

COMPETITION

     The Company operates in a highly competitive environment. It competes
directly and indirectly with other manufacturers of industrial and commercial
boilers and water desalination and process evaporation systems, as well as with
manufacturers of parts and components for all of the foregoing.

FOREIGN SALES

     Aqua-Chem does not rely on any one country for the majority of its foreign
sales. For a further discussion of sales by geographic area, see Note 14 to the
Company's Consolidated Financial Statements contained elsewhere herein.

REPORTING REQUIREMENTS

     The Company is required to file annual reports, documents and other reports
with the SEC by Section 13 or 15(d) of the Exchange Act, as well as pursuant to
the Indenture. These reports are required to be provided to the Trustee and
security holders and are intended to be the Company's form of reporting to its
security
                                        9
<PAGE>   12

holders. The Company's annual reports will contain certain financial information
which has been examined and reported on, with an opinion expressed by an
independent public or certified public accountant.

INTELLECTUAL PROPERTY

     The Company has a number of United States and foreign patents, patent
applications, patent licensing agreements, trademarks, trademark applications
and copyrights. The Company does not consider its business to be materially
dependent upon any patent, patent application, patent license agreement,
trademark, trademark application or copyright.

</TABLE>

---------------

(a)  The Company was formerly a limited partner in a partnership that owned this
     facility. In July 1998 the partnership sold this facility to a third party
     and the partnership was liquidated. The Company occupies the facility under
     a lease which expires in June 2006.

(b)  The Company plans to close the Greenville facility and transfer all
     production currently located there to other Company facilities. The process
     of transferring production is expected to be completed, and the Greenville
     facility closed during the first half of fiscal 2000. The Company has
     entered into an agreement with the union representing production workers at
     the Greenville facility regarding the transfer of production and closure of
     that facility. The Company occupies this facility under a year to year
     lease which automatically renews until 2061 unless terminated by either
     party upon six months' notice.

(c)  As of March 31, 1999, approximately 26% of the Company's employees were
     represented by various unions. The Company's agreements with its unions
     expire on June 5, 2000 in Stratford, Ontario; on February 1, 2000 in Mexico
     City, Mexico; on January 19, 2001 in Monroe, Wisconsin and on October 31,
     1999 in Lincoln, Nebraska. In the last five years the Company has
     experienced one strike, in 1994, by the employees represented by the
     International Boilermakers Union at NDC's main manufacturing facility in
     Lincoln. The strike lasted approximately six weeks in connection with a
     dispute over employee contributions for health benefits.

(d)  The Company occupies this facility under a lease which expires in November
     1999.

(e)  As of March 31, 1999 the Company's Lebanon, Pennsylvania facility, a
     164,000 square foot manufacturing plant, is partially leased to third
     parties. On May 27, 1999 the Company consummated the sale of this facility
     and received net proceeds of $1.2 million, which approximates its carrying
     value as reflected at March 31, 1999.

ITEM 3. LEGAL PROCEEDINGS.

ENVIRONMENTAL AND RELATED MATTERS

     The Company is subject to a variety of foreign, federal, state and local
laws and regulations relating to the use, storage, handling, generation,
transportation, treatment, emission, discharge, disposal and remediation of, and
exposure to, hazardous and non-hazardous substances, materials, and wastes
("Environmental Laws"). The Company is also subject to laws and regulations
governing employee health and safety.

     As part of the due diligence process associated with the Management Buy-Out
and the NDC Acquisition, environment audits were performed at all of the
Company's locations. The Company is in the process of taking action to implement
recommendations at certain on-site locations, which actions may include further
investigation or monitoring and possibly remediation. The Company does not
currently believe that the costs associated with these matters will have a
material adverse effect on the results of operations or the financial condition
of the Company.

                                       11
<PAGE>   14

     The Company has sold properties, and in certain cases, has retained
responsibility for environmental issues related to periods prior to the sale.
The Company is currently unaware of any subsequent property owners asserting
environmental claims related to such properties.

     Although the Company believes that there are no currently existing
environmental conditions that would require the Company to incur costs that
would have a material impact on the Company, there can be no assurance that
additional environmental situations will not arise or be discovered, either with
respect to the Company's existing or formerly owned facilities, which could have
a material adverse effect on the Company's business, results of operations or
financial conditions.

LEGAL PROCEEDINGS

     The Company has been named as one of a number of defendants in
approximately 8,900 lawsuits (of which approximately 6,100 are still pending)
alleging personal injury arising from exposure to asbestos-containing materials
allegedly contained in certain boilers manufactured by the Company or its
subsidiaries in the past. The Company believes that substantially all of these
lawsuits are without merit and has not admitted liability or been found liable
for the plaintiff's injuries in any of these cases. The Company has disposed of
the vast majority of the closed cases without any payment whatsoever by the
Company or its insurers to the plaintiffs, and is vigorously defending the open
cases, although many may not be resolved for several years. Because the
pleadings generally do not specify the amount of damages sought, and because the
Company is typically only one of numerous defendants initially named and it is
impossible to determine the Company's proportionate share of liability, if any,
to the plaintiffs, the Company cannot calculate its total potential liability in
these cases. However, based on its historical experience, the Company believes
that it has adequate indemnity as well as insurance coverage from a number of
different insurance carriers for any potential liability it may face as a result
of such claims, as well as liability resulting from its agreement to bear a
portion of the defense costs and indemnity payments with regard to these suits.
The Company has established a reserve on its balance sheet to cover any such
exposure and believes this reserve to be adequate. It is the view of management
that the final resolution of said claims and other similar claims which are
likely to arise in the future will not individually or in the aggregate have a
material effect on the Company's financial position or results of operations,
although no assurance to that effect can be given.

     The Company is involved in various other litigation matters arising in the
normal course of business. It is the view of management that the Company's
recovery or liability, if any, under pending litigation is not expected to have
a material effect on the Company's financial position or results of operations,
although no assurance to that effect can be given.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     No matters were submitted to a vote of security holders of the Company
during the fourth quarter of the fiscal year ended March 31, 1999.

                                    PART II

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
        MATTERS.

     There is no established public trading market for any equity securities of
the Registrant.

ITEM 6. SELECTED FINANCIAL DATA.

     The following table sets forth selected historical financial data of
Aqua-Chem as of and for: (i) the year ended December 31, 1996 derived from the

---------------

(a)  On July 31, 1997, Aqua-Chem management and its shareholders acquired
     Aqua-Chem in the Management Buy-Out, which was accounted for as a purchase.
     As a result, all periods presented prior to August 1, 1997 were prepared
     using Aqua-Chem's historical basis of accounting. All periods presented

                                       13
<PAGE>   16

     subsequent to July 31, 1997 reflect the fair values of the assets acquired
     and liabilities assumed in the Management Buy-Out.

(b)  For 1994 and 1995, reflects restructuring charges required to complete the
     1994 Restructuring. For 1996, reflects restructuring charges required to
     complete the 1996 Restructuring. For the year ended March 31, 1999,
     reflects restructuring charges to complete the 1998 and 1999
     Restructurings. For further information on such restructurings, see
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations of Aqua-Chem," and Note 3 to the Consolidated Financial
     Statements of Aqua-Chem included in Item 8 herein.

(c)  EBITDA is defined as operating income before depreciation and amortization.
     While EBITDA is not intended to represent cash flow from operations as
     defined by generally accepted accounting principles ("GAAP") and should not
     be considered as an indicator of operating performance or an alternative to
     cash flow (as measured by GAAP) as a measure of liquidity, it is included
     herein because management believes that certain investors find it to be a
     useful tool for measuring the ability of the Company to meet its future
     debt service capital expenditures and working capital requirements. When
     evaluating EBITDA, the Company's minimum annual principal repayments of
     long-term debt and other long-term commitments as well as cash flows from
     operating, investing, and financing activities should also be considered.
     See the Consolidated Statements of Cash Flows of Aqua-Chem and the related
     notes thereto included in Item 8 herein. In addition, see the Company's
     discussion of liquidity and capital resources as disclosed within
     Management's Discussion and Analysis of Financial Condition and Results of
     Operations of Aqua-Chem.

(d)  Adjusted EBITDA for the periods presented is defined as EBITDA excluding
     non-cash restructuring charges, and, in the five months ended December 31,
     1997 and the year ended March 31, 1999, excludes $687 and $1,796,
     respectively, of non-cash purchase accounting adjustments to cost of goods
     sold related to writing up inventory to fair market value at the time of
     the Management Buy-Out and at the time of the NDC Acquisition,
     respectively.

                       UNAUDITED PRO FORMA FINANCIAL DATA

     The unaudited pro forma financial data include the unaudited pro forma
consolidated statement of operations of the Company for the twelve months ended
December 31, 1997 (the "Pro Forma Statement of Operations"). The Pro Forma
Statement of Operations gives effect to the Management Buy-Out as if it had
occurred on January 1, 1997 and represents Aqua-Chem's Statement of Operations
for the period January 1, 1997 to July 31, 1997, prepared using Aqua-Chem's
historical basis of accounting and Aqua-Chem's Statement of Operations for the
period August 1, 1997 to December 31, 1997, prepared under a new basis of
accounting that reflects the fair values of assets acquired and liabilities
assumed, the related financing cost and all debt incurred in connection with the
Management Buy-Out, on a combined basis, adjusted as described in the footnotes.

     The Pro Forma Financial Statement is based on certain estimates and
assumptions made by the management of the Company as to the operations of
Aqua-Chem which the Company believes to be reasonable. The Pro Forma Financial
Statements do not purport to be indicative of the results of operations or
financial position of Aqua-Chem that actually would have been obtained had the
Management Buy-Out been completed as of the assumed date, or to project the
results of operations or financial position of the Company for any future date
or period.

     The Pro Forma Financial Statement should be read in conjunction with the
financial statements of Aqua-Chem included elsewhere herein. See also
"Management's Discussion and Analysis of Financial Condition and Results of
Operations of Aqua-Chem, Inc.".

     The Pro Forma Statement of Operations is included in order to make
comparisons to the years ended March 31, 1999 and December 31, 1996 in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations of Aqua-Chem, Inc.".

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

     The following discussion should be read in conjunction with, and is
qualified in its entirety by reference to, the consolidated financial statements
of Aqua-Chem appearing elsewhere herein. For information regarding the pro forma
financial condition of Aqua-Chem, see "Unaudited Pro Forma Financial Data" and
"-- Liquidity and Capital Resources."

     On December 30, 1998, Aqua-Chem elected to change the date of its fiscal
year-end to March 31. As a result, the fiscal year ended March 31, 1999 is
compared to the pro forma twelve months ended December 31, 1997. Additionally,
the three month transition period ended March 31, 1998 is included for
comparison against the three month period ended March 31, 1997.

     Due to purchase accounting adjustments resulting from the Management
Buy-Out on July 31, 1997, the seven-month period ended July 31, 1997 and the
five-month period ended December 31, 1997 are not comparable in all material
respects. The financial data for the seven-month period ended July 31, 1997 and
the five-month period ended December 31, 1997 are presented within "Selected
Financial Data of Aqua-Chem." The pro forma financial data for the twelve months
ended December 31, 1997 was prepared using Aqua-Chem's historical results for
the year then ended, adjusted to reflect the Management Buy-Out as if the
Management Buy-Out had occurred on January 1, 1997. See footnote (a) to the
Notes to Unaudited Pro Forma Consolidated Statements of Operations under
"Unaudited Pro Forma Financial Data." See also "Business -- History" for further
description of the Management Buy-Out. The pro forma financial data for the
twelve months ended December 31, 1997 is discussed below in order to make
comparisons to the years ended March 31, 1999 and December 31, 1996.

RESULTS OF OPERATIONS

     Composition of net sales and gross margins for Cleaver-Brooks, Water
Technologies and National Dynamics for the periods indicated is listed below, as
well as additional financial data.

<PAGE>   20

  Year Ended March 31, 1999 Compared To Twelve Months Ended December 31, 1997
(Pro Forma)

     Net Sales. Net sales for 1999 increased $29.2 million (15.3%) to $220.4
million from $191.2 million. This increase was attributable to the NDC
Acquisition which occurred on June 23, 1998. National Dynamics contributed $46.4
million in net sales since the date of acquisition. Net sales of Cleaver-Brooks
declined $15.2 million (9.8%). $6.0 million of the decrease resulted from the
sale of the contract machining business in October 1997 with the remainder
attributable to soft orders for watertube and firetube boilers. Net sales of
watertube boilers declined $7.2 million and $2.5 million for firetube boilers.
Within the firetube boilers net sales of the premium product declined $7.1
million which was partially offset by increases in the newly introduced,
baseline products. The declines are in substantial part the result of the
economic crisis in Asia and its effect on the domestic markets. Water
Technologies' sales decreased $2.0 million (5.5%) primarily due to a large
land-based water desalination project for which revenue was recognized during
fiscal 1997 without a similar project in 1999.

     Gross Margin. Gross margin increased $0.9 million (1.8%) in 1999 to $51.1
million from $50.2 million for 1997. The gross margin percentage decreased 3.1%
to 23.2% primarily due to the inclusion of National Dynamics operations for the
first time in 1998. Margins at National Dynamics reflected an inventory write-up
of $1.8 million at the date of the NDC Acquisition. This inventory was
substantially sold in the following quarter. Additionally, after adjustment for
the inventory write-up, National Dynamics' gross margin is 20.3% which is
substantially less than Aqua-Chem's normal margins without National Dynamics.
The gross margin percentage of Cleaver-Brooks declined 1.3% to 25.6%. This
decline is attributable to the shift in sales in of firetube boilers from the
premium product to the baseline product, which has a lower gross margin
percentage, as well as, manufacturing inefficiencies related to the closure of
the Greenville facility. Water Technologies' gross margin percentage declined
1.0% to 22.4%. This decline is attributable to the higher gross margin
percentage on the large land-based water desalination project in 1997.

     Selling, General and Administrative Expenses. Selling, general and
administrative expense increased $4.4 million (11.2%) in 1999 to $43.8 million.
The NDC Acquisition in June 1998 increased selling, general and administrative
expenses $5.2 million. This increase was partially reduced by reduced
commissions due to the decline in volume and reduced bonus and profit sharing
expenses due to the decreased profitability.

     Restructuring Charges. A restructuring charge of $4.7 million was recorded
in 1999 as a result of the Board of Directors' approval of the closure of the
Greenville, MS facility. The provision included $2.9 million to write down the
value of certain fixed assets, $1.0 million for employee termination payments
and $0.8 million for other costs related to closing the existing facility. In
response to a worldwide decline in demand for boiler equipment as compared to
previous years, Aqua-Chem approved the 1999 Restructuring Plan designed to
reduce headcount to mitigate the effects of this decreased demand. As a result,
Aqua-Chem recorded an additional restructuring charge of $1.2 million related to
employee termination payments and outplacement services.

     Operating Income. For the reasons set forth above, operating income
decreased $9.3 million to $1.5 million. Excluding the $5.9 million in total
restructuring charges, operating income decreased $3.4 million to $7.4 million
in fiscal 1999.

     Other Income (Expense). Other income (expense) for 1999 was an expense of
$12.3 million as compared to an expense of $5.1 million for 1997, resulting in a
difference of $7.2 million (141.2%). This difference is due to higher interest
expense as a result of the increased debt issued in conjunction with the
subordinated debt offering. See "-- Liquidity and Capital Resources."

  Twelve Months Ended December 31, 1997 (Pro Forma) Compared To Year Ended
  December 31, 1996

     Pro Forma Net Sales. Pro forma net sales declined $8.4 million (4.2%) in
1997 to $191.2 million from $199.6 million in 1996. Net sales attributable to
Cleaver-Brooks were relatively stable at $154.9 million in 1997, primarily due
to a decline of $5.5 million in sales to the Asia Pacific region and $2.0
million in reduced sales resulting from the sale of two small product lines,
offset by continued strong domestic demand for

                                       18
<PAGE>   21

firetube boilers. Net sales attributable to Water Technologies decreased $7.7
million (17.5%) to $36.3 million in 1997, primarily due to the deferral of
certain significant orders for water purification and treatment systems during
the period, partially offset by increased demand for distillation systems for
pharmaceutical and offshore oil applications.

     Pro Forma Gross Margin. Pro forma gross margin increased $4.1 million
(8.9%) in 1997 to $50.2 million from $46.1 million in 1996 despite a 4.2%
decline in net sales. Gross margin as a percentage of net sales improved to
26.3% in 1997 from 23.1% in 1996 due to (i) improved manufacturing efficiencies
at Aqua-Chem's Thomasville boiler plant, (ii) improvements in the product mix,
(iii) the completion of a large, unprofitable water purification and treatment
project in 1996 for which the Company accrued $2.0 million in 1996 for
additional estimated losses and (iv) the in-sourcing of certain key boiler
components.

     Pro Forma Selling, General and Administrative Expenses. Pro forma selling,
general and administrative expenses were $39.4 million in 1997, an increase of
$5.0 million (14.3%) from $34.4 million in 1996. Selling, general and
administrative expenses as a percentage of net sales was 20.6% in 1997 as
compared with 17.3% in 1996. This increase was due primarily to a $1.0 million
increase in information systems spending and increased travel expenditures
related to Aqua-Chem's sales and marketing efforts as such expenditures returned
to normalized levels following their curtailment in 1996.

     Restructuring Charges. Aqua-Chem did not record any restructuring charges
in 1997 as compared with $5.0 million in 1996 related to the 1996 Restructuring.

     Pro Forma Operating Income. For the reasons set forth above, pro forma
operating income increased $4.2 million (63.6%) in 1997 to $10.8 million from
$6.6 million in 1996.

     Pro Forma Other Income (Expense). Pro forma other income (expense) for 1997
was an expense of $5.1 million as compared to an expense of $1.8 million in
1996, resulting in an increase of $3.3 million (183.1%). This difference was due
primarily to the increase in interest expense of $4.3 million as a result of
increased debt issued in conjunction with the Management Buy-Out. This increase
is offset by a $0.3 million loss recorded in 1996 for additional charges related
to a disposed product line.

  Seven Months Ended July 31, 1997 And Five Months Ended December 31, 1997

     In addition to the comparative analysis of the pro forma operating results
for the year ended December 31, 1997 presented above, the following paragraphs
will specifically address the actual results for the seven months ended July 31,
1997 and the five months ended December 31, 1997. As noted on the accompanying
Selected Financial Data table, these periods have a different basis of
accounting as a result of the Management Buy-Out effective on July 31, 1997. For
a comparative analysis of the 1997 operating results to 1996, see the narrative
presented above.

     Net Sales and Gross Margin. Net sales and gross margin for the seven months
ended July 31, 1997 were $99.6 million and $26.0 million, respectively. The net
sales and gross margin for the five months ended December 31, 1997 were $91.5
million and $25.2 million, respectively. The gross margin as a percentage of net
sales for those periods was 26.1% and 27.5%, respectively. The higher gross
margin for the five month period of December 31, 1997 results from the mix of
products and higher production levels in that period. A comparison to 1996 gross
margin levels is described above.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the seven months ended July 31, 1997 and five months
ended December 31, 1997 were $23.3 million and $17.1 million, respectively. This
represents 23.4% and 18.7% as a percentage of net sales for the respective
periods. The significantly higher costs as a percentage of sales in the seven
months ended July 31, 1997, is attributable to higher information systems costs
and travel expenses in the first seven months of the year. These amounts also
include certain payments to management in conjunction with the Management
Buy-Out of $1.3 million.

     Other Income. Other income (expense) for the seven months ended July 31,
1997 and the five months ended December 31, 1997 was ($193) and ($2,300),
respectively. The substantially higher expenses in the

                                       19
<PAGE>   22

five months ended December 31, 1997 result primarily from the higher interest
expense associated with the increased debt issued in conjunction with the
Management Buy-Out.

  Three Months Ended March 31, 1998 Compared To Three Months Ended March 31,
1997

     Net Sales. Net sales for the three month period ended March 31, 1998
increased $1.8 million (5.2%) to $36.8 million from $35.0 million. Net sales
attributable to Cleaver-Brooks increased $0.8 million (2.9%). The increased
sales resulted from volume improvements for firetube boilers, commercial
watertube boilers and parts and a substantial increase in Cleaver-Brooks de
Mexico's operation with an offsetting decrease resulting from the sale of the
contract machining business in October, 1997 representing $       of the
offsetting decrease. Net sales attributable to Water Technologies increased $1.0
million (13.0%) to $8.7 million, primarily due to a large land-based water
desalination project.

     Gross Margin. Gross margin increased $0.6 million (6.8%) to $9.3 million
from $8.7 million for the same period in 1997. The gross margin percentage
improved to 25.2% from 24.9% primarily due to continued improvements in
throughput in Cleaver-Brooks' manufacturing facilities and improved parts
margins at Cleaver-Brooks.

     Selling, General and Administrative Expenses. Selling, general and
administrative expense increased $0.5 million (5.7%) to $8.9 million, primarily
due to continued increased commissions earned by sales representatives from the
higher sales volume and higher costs reported by the Mexico operations resulting
from consolidation of an additional month of operating results with Aqua-Chem.
Selling, general and administrative expense as a percentage of net sales was
24.2% compared to 24.1% for the prior year period.

     Operating Income. For the reasons set forth above, operating income
increased $0.1 million, to $0.4 million from $0.3 million for the three month
period ended March 31, 1997.

     Other Income (Expense). Other income (expense) for the three months ended
March 31, 1998 was an expense of $1.4 million as compared to an expense of $0.1
million for the same period in 1997, resulting in a difference of $1.3 million
(1193.5%). This difference is due to increased debt issued in conjunction with
the Management Buy-Out.

LIQUIDITY AND CAPITAL RESOURCES

     Cash used in operating activities was $2.9 million for the year ended March
31, 1999 compared to cash provided of $14.2 million for the twelve months ended
December 31, 1997. The decrease of $17.1 million was attributable primarily to
additional interest payments related to the Subordinated Notes described below
and an increase in accounts receivable due to slower collection related to
National Dynamics. For the fiscal year ended December 31, 1996, cash provided by
operating activities was $8.1 million.

     Cash used in investing activities was $51.9 million for the year ended
March 31, 1999 compared to $51.8 million for the twelve months ended December
31, 1997 and $1.0 million in 1996. The current period included $48.5 million for
the NDC Acquisition. Capital expenditures for the current period were $3.2
million as compared to $3.4 million for the twelve months ended December 31,
1997 and $2.8 million in fiscal 1996. These expenditures relate to ongoing
maintenance and upgrades to Aqua-Chem's manufacturing equipment and facilities
and to certain replacement software systems. The twelve months ended December
31, 1997 included $52.1 million used for the Management Buy-Out.

     Cash provided by financing activities was $55.4 million for the year ended
March 31, 1999 compared to $40.7 million in the twelve months ended December 31,
1997 and $1.5 million in 1996. The year ended March 31, 1999 included $125.0
million in proceeds from the Subordinated Notes issued in connection with the
NDC Acquisition and repayments of $63.1 million, of which $60.1 million related
to repayment of debt incurred as a result of the Management Buy-Out and $3.0
million related to the redemption for a portion of the Preferred A stock issued
in connection with the Management Buy-Out. The twelve months ended December 31,
1997 included $65.6 million in proceeds from debt issued in connection with the
Management Buy-Out and repayments of $26.0 million, of which $20.0 million
related to repayment of debt outstanding at

                                       20

the time of the Management Buy-Out and $6.0 million related to repayment of debt
incurred as a result of the Management Buy-Out.

BORROWING AVAILABILITY AND LIMITATIONS.

     The Company has a revolving credit facility that provides $45.0 million of
borrowing availability and is secured by substantially all assets of the
Company. Under the revolving credit facility the Company is required to maintain
an adjusted consolidated tangible net worth (consolidated tangible net worth
plus an amount equal to the aggregate outstanding principal amount of
subordinated debt) of not less than $70 million plus (on a cumulative basis) for
each fiscal quarter ending on or after June 23, 1998, the sum of (a) 50% of
consolidated net income if positive and 100% of the cash proceeds of the
issuance of any equity interest of the Company during such fiscal quarter. In
addition, the revolving credit facility as amended on May 25, 1999 requires the
Company to maintain (i) a fixed charge coverage ratio of not less than 1.0 to 1
for the quarters ended June 30, 1999 and September 30, 1999, 1.10 to 1 for the
quarter ended December 31, 1999, 1.15 to 1 for the quarter ended March 31, 2000
and 1.25 to 1 for each subsequent quarter, and (ii) a senior funded debt to
consolidated EBITDA ratio of not more than 3.5 to 1.

     The Company intends to fund future working capital, capital expenditures
and debt service requirements through cash flows generated from operating
activities and from borrowings under the revolving credit facility. Management
believes it will begin to borrow under the revolving credit facility during
fiscal 2000, but that cash flows for the balance of the year will allow for the
repayment of these borrowings by year end.

     At March 31, 1999 the Company had $125 million of 11 1/4% Senior
Subordinated Notes (the "Notes") outstanding under an Indenture dated June 23,
1998 (the "Indenture"). The Indenture generally prohibits the incurrence by the
Company of additional debt unless the Company satisfies one of two requirements,
the Coverage Limitation or the Basket Limitation described below. Under the
Coverage Limitation, the Company may not incur additional indebtedness unless,
on the date of such incurrence and after giving effect thereto, the Consolidated
Coverage Ratio exceeds 2.0 to 1 if such indebtedness is incurred prior to
January 1, 2000, 2.25 to 1 if such indebtedness is incurred on or after January
1, 2000 and prior to January, 2001 or 2.5 to 1 thereafter (the "Coverage
Limitation"). As of March 31, 1999, the Company could not have incurred any
additional Indebtedness under the Coverage Limitation.

     The Indenture permits the Company to incur additional indebtedness of
certain types up to certain limitations applicable to each type (the "Basket
Limitation") notwithstanding the Coverage Limitation. The Company could have
incurred approximately $80.6 million of additional indebtedness under the Basket
Limitations on March 31, 1999, including the following: (a) indebtedness
pursuant to the revolving credit agreement of up to the greater of (i) $45.0
million or (ii) the sum of 50% of the book value of inventory and 85% of the
book value of accounts receivable as of such date (the limitation under clause
(ii) would have been approximately $47.3 million at March 31, 1999); (b)
indebtedness by foreign subsidiaries not exceeding the sum of (i) 60% of the
book value of inventory and (ii) 85% of the book value of accounts receivable;
(c) purchase money indebtedness not exceeding the greater of (i) $20 million or
(ii) 5% of the consolidated net worth of the Company; and (d) an additional $10
million without regard to the nature or purpose of such indebtedness.

     The Company expects that its cash needs for debt service under the
Indenture during the fiscal 2000 will be approximately $14.1 million. Mandatory
repayments of the Company's outstanding indebtedness and mandatory redemptions
of the Company's outstanding Series A Preferred Stock subsequent to March 31,
2000 are $1 million, $1 million and $125 million in fiscal year 2001, fiscal
year 2002 and subsequent fiscal years, respectively.

     During the year ended March 31, 2000, the Company expects to make
approximately $2.8 million of capital expenditures related to the Thomasville
facility to improve the facility's efficiency. Apart from this item, the Company
believes that its manufacturing facilities and computer software and hardware
are generally adequate to meet projected needs. Additionally, the Company
expects other capital expenditures of $3.1 million.

                                       21
<PAGE>   24

     Management believes that cash generated from operating activities together
with borrowing availability under the revolving credit facility will be adequate
to cover the Company's working capital, preferred stock redemption, debt service
and capital expenditure requirements on a short and long term basis.

     At March 31, 1999, the Company had no material market risk exposure (e.g.,
interest rate risk, foreign currency exchange rate risk or commodity price
risk).

YEAR 2000

     Many computer software applications, hardware and equipment and embedded
chip systems identify dates using only the last two digits of the year. These
products may be unable to distinguish between dates in the year 2000 and dates
in the year 1900. That inability (referred to as the "Year 2000 Issue"), if not
addressed, could cause applications, equipment or systems to fail or provide
incorrect information after December 31, 1999, or when using dates after
December 31, 1999. The Company uses a number of computer software programs,
operating systems, and types of equipment with computer chips in its internal
operations, including applications used in its financial business systems, order
entry and manufacturing systems, manufacturing processes and administrative
functions. The Company also manufactures products that incorporate components
purchased from other manufacturers that contain computer chips. To the extent
that the above listed items contain source code or computer chips that are
unable to interpret appropriately the upcoming calendar year 2000,
distinguishing it from the year 1900, some level of modification or possible
replacement will be necessary.

     State of Readiness -- The Company has assessed and continues to assess the
impact of the Year 2000 Issue on its operations. The Company's assessments have
focused on the three major elements of the Year 2000 Issue: IT systems; Non-IT
systems; and third party relationships.

     IT Systems -- Since 1996 the Company has been executing an IT system
upgrade plan, which includes leasing a new mainframe computer at an annual cost
of $0.6 million, and the expansion of and improvements to its networks and
capital spending on hardware totaling $0.2 million. Additionally, the Company
has spent $2.0 million on new financial systems software, of which $1.8 million
has been capitalized. These systems are replacing software that has been in use
since the early 1980's. The IT system upgrade plan was not undertaken in
response to the Year 2000 Issue, nor was it accelerated due to the Year 2000
Issue.

     Of these new financial systems, the general ledger, accounts receivable,
accounts payable and reporting packages have been implemented, while the human
resource/payroll package is in the installation phase with a September 1999
targeted completion date. Management believes this project is currently on
schedule to meet this target date.

     The Company has received written assurances from the manufacturers that the
following hardware and software are Year 2000 compliant as a result of the IT
upgrade plan: mainframe hardware; mainframe systems software; mainframe
operating system; LAN/WAN hardware; LAN/WAN operating systems; LAN/WAN system
software; personal computers and related software; and financial systems
software.

     The Company's order entry and manufacturing systems are in the process of
being upgraded to address the Year 2000 Issue. The databases for all these
systems have been expanded and regenerated. Some of these systems have been put
into production. Management believes the remaining systems are on schedule to be
placed into production in August, 1999. Other non-Year 2000 IT efforts have not
been materially delayed or impacted by Year 2000 initiatives.

     Non-IT Systems -- The Company has reviewed all of its communication systems
(phone and data transmission systems), fax machines, photocopiers, postage
machines, elevators, HVAC systems, security systems and shop floor equipment
with the manufacturers or vendors of those systems and equipment and has
received verbal assurances that these systems are Year 2000 compliant. Written
certifications of Year 2000 compliance for these systems have been requested
from the manufacturers or vendors. The Company is currently reviewing the
responses it has received to date and has sent a follow up letter to any
manufacturers or vendors who have not responded.

                                       22
<PAGE>   25

     Third Party Relationships -- All of the Company's suppliers of raw
materials, components, and other goods and services have been sent a
questionnaire regarding their Year 2000 compliance and their plans to be Year
2000 compliant. Over 75% of the suppliers contacted have responded. A follow up
letter has been sent to those suppliers who have yet to respond. For those
remaining suppliers who do not respond to this questionnaire, or who do not have
a Year 2000 compliance plan in place, the Company has identified alternative
suppliers and will use an alternative supplier who has certified that it is Year
2000 compliant. For all suppliers of equipment containing computer chips which
are incorporated into the Company's products, the Company has received written
assurance that this equipment is Year 2000 compliant.

     Costs to Address the Company's Year 2000 Issue -- Costs incurred by the
Company to date to address the Year 2000 Issue, excluding the IT system upgrade
costs, are approximately $0.3 million. The Company estimates total costs
remaining to be incurred prior to the year 2000 range from $0.1 million to $0.2
million. Maintenance or modification costs will be expensed as incurred, while
the costs of new software will be capitalized and amortized over the software's
useful life. These costs will be funded from operating cash flows.

     Risks and Contingency Plans -- Although the Company believes its efforts
will adequately address its Year 2000 Issue internally, it is possible that the
Company will be adversely affected by problems encountered by its vendors or
suppliers. Despite any vendor's or supplier's certification regarding Year 2000
compliance, there can be no assurance that the vendor's or supplier's ability to
provide goods and services will not be adversely affected by the Year 2000
Issue. The most likely worst case scenario would be that a failure by the
Company or one or more of its vendors or suppliers to adequately and timely
address the Year 2000 Issue interrupts manufacturing of the Company's products
for a undeterminable period of time. The Company has identified and will
continue to identify alternative vendors should a vendor's ability to meet the
Company's raw material and supply requirements be impacted by the Year 2000
Issue. While the Company believes it can minimize the impact of such
non-compliance through the use of these alternative vendors, a disruption in
production could have a material adverse impact on the Company. The Company does
not currently expect to develop a formal contingency plan.

GENERAL

     The costs of the Company's efforts to address the Year 2000 Issue and the
dates on which the Company believes it will complete such efforts are based upon
management's best estimates, which were derived using numerous assumptions
regarding future events. There can be no assurance that these estimates will
prove to be accurate, and actual results could differ materially from those
currently anticipated. Specific factors that could cause such material
differences include, but are not limited to, the Company's ability to identify,
assess, remediate and test relevant computer codes and embedded technology, the
Company's reliance on third-party assurances and the variability of definitions
of "Year 2000 compliance" which may be used by such third parties, and similar
uncertainties.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and
Shareholders of Aqua-Chem, Inc.:

     We have audited the accompanying consolidated balance sheets of Aqua-Chem,
Inc. and subsidiaries as of March 31, 1999 and December 31, 1997 and the related
consolidated statement of operations, stockholders' equity and cash flows for
the year ended March 31, 1999, the period from January 1, 1998 to March 31,
1998, the period from August 1, 1997 to December 31, 1997 and the period from
January 1, 1997 to July 31, 1997. These financial statements and the
supplemental schedule referred to below are the responsibility of Aqua-Chem's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Aqua-Chem,
Inc. and subsidiaries as of March 31, 1999 and December 31, 1997, and the
results of their operations and their cash flows for the year ended March 31,
1999, the period from January 1, 1998 to March 31, 1998, the period August 1,
1997 to December 31, 1997 and the period from January 1, 1997 to July 31, 1997,
in conformity with generally accepted accounting principles.

     Our audits were made for the purpose of forming an opinion on the
consolidated financial statements taken as a whole. The supplemental schedule,
Schedule II -- Valuation and Qualifying Accounts, is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not a
required part of the basic financial statements. The supplemental schedule has
been subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, fairly states in all material respects
the financial data required to be set forth therein in relation to the basic
financial statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS; EXCEPT PER SHARE DATA)

NOTE 1: MANAGEMENT BUY-OUT AND NDC ACQUISITION

     On July 31, 1997, Aqua-Chem, Inc. ("OLDCO") entered into a definitive
merger agreement with A-C Acquisition Corp. ("A-C Acquisition"), a 100% owned
subsidiary of Rush Creek LLC ("Rush Creek"). Rush Creek is a Limited Liability
Company owned by certain management of OLDCO and Whitney Equity Partners, L.P.
Also on July 31, 1997, pursuant to the merger, A-C Acquisition Corp. acquired
the assets of OLDCO (the "Management Buy-Out") for $125,747, which included
$69,196 of liabilities assumed and $5,000 of Series A Cumulative Preferred Stock
issued to the sellers. The amount paid or assumed does not include contingent
consideration attached to the Series B Cumulative Preferred Stock to be paid to
the sellers based on cumulative earnings of certain operations of OLDCO
subsequent to the Management Buy-Out. Maximum additional consideration is $7,500
and will be settled as part of the Series B Cumulative Preferred Stock as
discussed in Note 10.

     Concurrently with the Management Buy-Out, A-C Acquisition amended its
certificate of incorporation to change its name to Aqua-Chem, Inc., (hereinafter
referred to as "Aqua-Chem"). The Management Buy-Out was accounted for using the
purchase method of accounting. The total purchase cost was allocated first to
the identified tangible and intangible assets and liabilities of OLDCO based
upon their respective fair values, with the remainder of $9,689 being allocated
to goodwill, which will be amortized on a straight-line basis over 40 years.

     Prior to the Management Buy-Out, OLDCO was an 80% owned subsidiary of
Lyonnaise American Holding, Inc.

     On June 23, 1998, Aqua-Chem acquired substantially all the assets of
National Dynamics Corporation ("NDC") for $65,838, which includes $17,338 of
liabilities assumed and now conducts NDC's former operations through its
National Dynamics Division ("National Dynamics"). The acquisition was accounted
for using the purchase method of accounting. The total purchase cost was
allocated first to identified tangible assets and liabilities based upon their
respective fair values, with the remainder of $27,351 being allocated to
goodwill, which will be amortized on a straight-line basis over 40 years. The
financial statements reflect the preliminary estimates of allocating purchase
price and may be revised at a later date. The Company does not expect the final
purchase price allocation to be materially different from preliminary estimates.

     The following information presents unaudited pro forma condensed
consolidated statements of operations assuming OLDCO had been acquired by
Aqua-Chem as of January 1, 1996 and that the acquisition of NDC occurred as of
January 1, 1997. Such information includes adjustments to reflect additional
interest expense and depreciation expense, amortization of goodwill and other
intangibles and a reduction of other expenses due to Management Buy-Out related
compensation payments being made by OLDCO.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Management Buy-Out or the acquisition of NDC been effective at the beginning of
the periods presented or of future operations of Aqua-Chem.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES

  (a) Basis of Presentation

     The consolidated financial statements for the period from January 1, 1997
to July 31, 1997 and for the year ended December 31, 1996, were prepared using
OLDCO's historical basis of accounting (the "pre-Buy-Out basis of accounting").
The consolidated financial statements for the year ended March 31, 1999 and the
periods January 1, 1998 to March 31, 1998 and August 1, 1997 to December 31,
1997 were prepared under a new basis of accounting that reflects the fair values
of assets acquired and liabilities assumed, the related financing costs and all
debt incurred in connection with the acquisition of OLDCO by Aqua-Chem (the
"post-Buy-Out basis of accounting"). Accordingly, the accompanying financial
statements are not comparable in all material respects since those financial
statements report financial position, results of operations, and cash flows of
two separate entities.

  (b) Consolidation Policy and Use of Estimates

     The consolidated financial statements include the accounts of Aqua-Chem and
all of its majority-owned subsidiaries. All significant intercompany accounts
and transactions have been eliminated in consolidation.

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities and the
disclosure of commitments and contingent liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

  (c) Inventories

     Inventories are stated at cost determined on the first-in, first-out (FIFO)
basis. The resulting inventory values are not in excess of market. Inventory
cost includes material, labor, burden, and engineering.

     Inventories consist of the following:

  (d) Property, Plant and Equipment

     Prior to August 1, 1997, property, plant and equipment was carried at cost,
less allowances for depreciation and adjustments to net realizable value, and
included expenditures which substantially increased the existing useful lives of
plant and equipment. Depreciation of plant and equipment was provided over the
estimated useful lives of the respective assets using accelerated methods for
both financial statement and income tax purposes.

     Effective with the Management Buy-Out, property, plant, and equipment were
adjusted to estimated fair values and are being depreciated on a straight-line
basis. The lives used for depreciation calculations are as follows: 20 years for
buildings and building improvements; 3 to 15 years for machinery and equipment;
and 3 to 10 years for furniture and fixtures. Leasehold improvements are
depreciated over the term of the related

lease. Depreciation expense totaled $4,382, $590, $984, $1,622, and $2,865, for
the year ended March 31, 1999, the period January 1 to March 31, 1998, the
period August 1 to December 31, 1997, the period January 1 to July 31, 1997, and
the year ended December 31, 1996, respectively.

  (e) Goodwill and Intangible Assets

     Goodwill is being amortized on a straight-line basis over 40 years. At
March 31, 1999, and December 31, 1997, goodwill totaled $36,007, and $9,467,
respectively, net of accumulated amortization of $1,033 and $222, respectively.
Amortization expense totaled $747, $286, and $222, for the year ended March 31,
1999, the period January 1 to March 31, 1998, and the period August 1 to
December 31, 1997, respectively.

     Aqua-Chem continually evaluates whether events and circumstances have
occurred that indicate the remaining estimated useful life of goodwill may
warrant revision or that the remaining balance of goodwill may not be
recoverable. When factors indicate that goodwill should be evaluated for
possible impairment, Aqua-Chem uses an estimate of the undiscounted cash flows
over the remaining life of the goodwill in measuring whether the goodwill is
recoverable.

     Prior to August 1, 1997, intangible assets, principally licenses and
technology, were carried at cost, less allowances for amortization. Amortization
of intangible assets was provided on the straight-line basis over the estimated
useful lives of the respective asset.

     Effective with the Management Buy-Out, intangible assets were adjusted to
estimated fair values and are being amortized on a straight-line basis over
estimated useful lives ranging from 5 to 17 years. At March 31, 1999 and
December 31, 1997, intangibles totaled $1,738 and $707, respectively, net of
accumulated amortization of $301 and $51, respectively. Amortization expense
totaled $250, $33, $51, $68, and $119, for the year ended March 31, 1999, for
the period January 1 to March 31, 1998, for the period August 1 to December 31,
1997, for the period January 1 to July 31, 1997, and the year ended December 31,
1996, respectively.

  (f) Income Taxes

     Aqua-Chem accounts for income taxes under Statement of Financial Accounting
Standards ("SFAS") No. 109, "Accounting for Income Taxes". Deferred tax assets
and liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases, and operating loss and tax
credit carryforwards. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. The effect
on deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date. In assessing the
realizability of deferred tax assets, Aqua-Chem considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the years in which those temporary
differences become deductible. Aqua-Chem considers the scheduled reversal of
deferred tax liabilities, projected future taxable income, and tax planning
strategies in making this assessment.

     Prior to the Management Buy-Out, Aqua-Chem filed a consolidated United
States corporate income tax return with Lyonnaise American Holding,
Inc.(Parent). The tax liability was calculated consistent with the provisions of
a 1984 tax allocation agreement with the Parent which provided for the
allocation of income tax expense (benefit) based principally on a consolidated
return basis.

  (g) Revenue Recognition

     Aqua-Chem recognizes revenue utilizing the completed contract method of
accounting, except for certain contracts meeting the criteria for percentage of
completion revenue recognition under Statement of
                                       33
<PAGE>   36
                                AQUA-CHEM, INC.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Position ("SOP") No. 81-1. For those contracts under the completed contract
method, revenue is recognized upon shipment of the finished product to the
customer. Under the percentage of completion method, earned revenue is based on
the percentage that incurred costs to date bear to estimates of total costs. The
cumulative impact of revisions in total cost estimates during the progress of
work is reflected in the year in which these changes become known. Earned
revenue reflects the original contract price adjusted for agreed upon change
order revenue, if any. Losses expected to be incurred on jobs in process, after
consideration of estimated recoveries on change orders, are charged to
operations as soon as such losses are known. Progress billings in accounts
receivable are currently due. Estimated revenues in excess of progress billings
and billings in excess of estimated revenues are disclosed in Note 4.

     Aqua-Chem has numerous contracts that are in various stages of completion.
Such contracts require estimates to determine the appropriate cost and revenue
recognition. Aqua-Chem has a substantial history of making reasonably dependable
estimates of the extent of progress towards completion, contract revenues and
contract costs. However, current estimates may be revised as additional
information becomes available.

  (h) Retainages

     Retainages are unpaid amounts due in accordance with the specific terms of
boiler contracts. Certain contracts provide for a percentage of the total
billing price to be retained by the customer until final acceptance of the
product. The amount of retainages included in Aqua-Chem's accounts receivable
balance was $2,241 and $1,485 at March 31, 1999 and December 31, 1997,
respectively.

  (i) Foreign Currency Translation

     All assets and liabilities of foreign subsidiaries are translated at the
exchange rate prevailing at the balance sheet date and all income and expense
accounts are translated at the average exchange rate in effect during the year.
Translation adjustments are accumulated as a component of accumulated other
comprehensive income (loss) or directly to the consolidated statements of
operations for those countries whose currency has been classified as highly
inflationary. Foreign exchange transaction gains(losses) were not material for
all periods presented in the consolidated statement of operations.

  (j) Commissions Payable

     Aqua-Chem's domestic and international sales representatives sell products
on a commission basis. The related commissions payable were $2,664 and $2,580 at
March 31, 1999 and December 31, 1997, respectively, and are included in accounts
payable-other.

  (k) Start-Up Accrual

     Included in the sales price of Aqua-Chem's products is an estimated future
cost to prepare the product for use. These future costs, referred to as start-up
costs, are accrued by Aqua-Chem at the time of sale. When the customer is ready
for start-up, the service is requested through the sales representative who
performs the necessary work to prepare the product for use. The sales
representative then bills Aqua-Chem for the cost of the work performed. At March
31, 1999 and December 31, 1997, Aqua-Chem had accrued $3,375 and $3,751,
respectively, for future start-up costs, which are included in accrued expenses.

  (l) Warranty Costs

     Aqua-Chem accrues estimated warranty costs at the same time revenues are
recognized. Reserves for warranty costs were $3,924 and $3,646 at March 31, 1999
and December 31, 1997, respectively, and are included in accrued expenses.

  (m) Research and Development

     Research and development costs are expensed as incurred and are included in
selling, general, and administrative expenses. Research and development expense
totaled $2,746, $484, $872, $1,305, and $2,244, for the year ended March 31,
1999, the period January 1 to March 31, 1998, the period August 1 to December
31, 1997, the period January 1 to July 31, 1997, and the year ended December 31,
1996, respectively.

  (n) Advertising

     Advertising costs are expensed as incurred and are included in selling,
general and administrative expenses. Advertising expense totaled $1,042, $300,
$392, $625, and $856, for the year ended March 31, 1999, the period January 1 to
March 31, 1998, the period August 1 to December 31, 1997, the period January 1
to July 31, 1997, and the year ended December 31, 1996, respectively.

  (o) Cash Equivalents

     For purposes of the consolidated statements of cash flows, Aqua-Chem
considers all highly liquid investments purchased with an original maturity of
three months or less to be cash equivalents.

  (p) Fair Value of Financial Instruments

     The carrying amounts of financial instruments approximate fair value due to
the short maturity of these instruments unless otherwise stated. The carrying
amounts of the long-term debt and short-term borrowings approximate fair value
because their stated interest rates approximate current rates for similar
instruments with similar maturities as of March 31, 1999 and December 31, 1997.

  (q) New Accounting Pronouncements

     Effective December 31, 1997, Aqua-Chem adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS No. 130").
This statement establishes standards for reporting and display of comprehensive
income which includes foreign currency translation adjustments accounted for
under SFAS No. 52. SFAS No. 130 requires that an enterprise classify items of
other comprehensive income by their nature in a financial statement for the
period in which they are recognized. Aqua-Chem has chosen to disclose
comprehensive income in the Consolidated Statement of Stockholders' Equity.
Accumulated other comprehensive income at March 31, 1999 and December 31, 1997
is comprised of only foreign currency translation adjustments. Prior years have
been restated to conform to the SFAS No. 130 requirements.

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. This statement must be adopted no later than April 1, 2001,
although earlier application is permitted. The Company is currently evaluating
the impact of adopting SFAS No. 133 but does not expect the impact to be
material to its financial position.

     Effective April 1, 1998, the Company adopted SOP No. 98-1, "Accounting for
the Costs of Computer Software Developed or Obtained for Internal Use." The
adoption of this statement did not have an effect on the Company's financial
position or results of operations.

     The Company will adopt SOP No. 98-5, "Reporting on the Costs of Start-Up
Activities," effective April 1, 1999. The Company believes that the adoption of
this statement will have no effect on the Company's financial position or
results of operations.

  (r) Reclassifications

     Certain 1997 and 1996 amounts as originally reported have been reclassified
to conform with the 1999 presentation.

  (s) Extraordinary Item

     On June 23, 1998, Aqua-Chem issued $125,000 of senior subordinated notes.
Proceeds from this offering were used, in part, to repay the secured term loan
and subordinated debt issued in conjunction with the Management Buy-Out.

     As a result of the repayment of the aforementioned borrowings, Aqua-Chem
recorded a $1,260 extraordinary, after-tax charge for the write-off of
unamortized deferred financing fees established at the time of the Management
Buy-Out in July, 1997.

  (t) Change in Fiscal Year

     On December 30, 1998, Aqua-Chem elected to change the date of its fiscal
year-end to March 31. As a result, a transition period for the three months
ended March 31, 1998 and the three months ended March 31, 1997 (unaudited), was
previously reported on a transition report on Form 10-Q. The three months ended
March 31, 1998 have been included in Aqua-Chem's Consolidated Statement of
Operations.

     The following is condensed unaudited operating results for the three months
ended March 31, 1997:

NOTE 3: RESTRUCTURING CHARGES

  1996 Restructuring Program

     During 1996, Aqua-Chem adopted a restructuring plan ("1996 Plan") focused
on improving overall performance and profitability. The 1996 Plan included an
early retirement program for 47 salaried individuals and certain organizational
changes within its operating units. As a result, a restructuring charge of
$5,038 was recorded in 1996.

  1998 Restructuring Program

     On June 25, 1998 the Board of Directors approved a plan of closure for the
Greenville, Mississippi facility ("1998 Plan"). As a result, the Company
recorded a restructuring charge of $4,720 to operations in June 1998. The 1998
Plan will result in the elimination of 149 positions and closure of the facility
within approximately one year from the date of approval. The majority of the
work currently performed at the facility will be transferred to other Company
facilities while the remainder will be outsourced.

     An analysis of Aqua-Chem, Inc.'s 1998 Plan is summarized in the table
below:

</TABLE>

     The $2,900 write down of assets represents the estimated impairment of
assets at the Greenville facility as a direct result of the Company's decision
to close this facility. The impairment write down was based upon the estimated
fair value of the assets at the date of commitment as compared to their carrying
values.

     The $955 of employee termination payments represents the employee cash
severance costs to reduce personnel as a result of the closure of the Greenville
facility. These termination payments include the cost of severance and
contractual benefits in accordance with collective bargaining arrangements and
Company policy.

     The remaining charge includes facility exit costs, such as employee costs
associated with the plant closure that will be incurred after operations cease
and the write-off of other plant-related assets not included in property, plant
and equipment related to the closure of the Greenville facility.

     Management believes the restructuring reserve balance of $1,691 at March
31, 1999, is adequate to carry out all activities under the 1998 Plan, and the
Company anticipates that all actions will be completed by the second quarter of
fiscal 2000.

  1999 Restructuring Program

     In January 1999, Aqua-Chem recognized a restructuring charge of $1,161
("1999 Plan"). The charge for the 1999 Plan consists of employee termination
payments associated with the termination of 35 personnel. These termination
payments include the cost of severance and outplacement services. As of March
31, 1999, the Company had payments of $321 against this reserve. Management
believes that the remaining balance of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

$840 at March 31, 1999, is adequate to carry out all activities under the 1999
Plan, and the Company anticipates that all actions will be completed by the
second quarter of fiscal 2000.

     The Company expects to fund the cash requirements of the 1998 and 1999
Plans with cash flows from operations and if necessary additional borrowings
under the Company's existing revolving credit facility. The specific
restructuring measures and associated estimated costs were based on management's
best business judgment under prevailing circumstances. If future events warrant
changes to the reserve, such adjustments will be reflected as "Restructuring
charges" in the applicable statement of operations.

     A portion of the tax loss incurred for the year ended March 31, 1999 will
result in a refund of prior taxes paid. Accordingly, a refund receivable of
$1,324 has been recorded within prepaid expenses and other current assets at
March 31, 1999.

     During 1995, Aqua-Chem incurred a net operating loss for tax purposes. Due
to a January 1996 modification to the existing tax allocation agreement between
Aqua-Chem and the former owners, a carryback of the loss would not have resulted
in a refund of cash to Aqua-Chem. Accordingly, Aqua-Chem elected to carry the
tax loss forward and a valuation allowance was established. During the period
January 1, 1997 through July 31, 1997 and the year ended December 31, 1996,
Aqua-Chem had sufficient income to realize the value of a portion of the net
operating loss. Accordingly, the valuation reserve was reduced in both periods
by the amount of the benefit realized.

     The Company has a tax loss carryforward of $5,800 for Federal income tax
purposes which expires in 2019. For state income tax purposes, the Company has
tax loss carryforwards in varying amounts ranging from $82 to $3,272 in the
states in which it has significant operations. These loss carryforwards expire
in years ranging from 2004 to 2019.

NOTE 10: STOCKHOLDERS' EQUITY AND PREFERRED STOCK WITH MANDATORY REDEMPTION
PROVISIONS

     As of March 31, 1999, Aqua-Chem had 2,006,260 shares of authorized capital
stock, itemized by class and series as follows:

          (i) 2,000,000 shares of Common Stock, par value $.01 per share, with
     1,000,000 shares issued and outstanding;

          (ii) 6,260 shares of Preferred Stock, par value $.01 per share,
     divided into the following series:

             (a) 130 shares of Series A Cumulative Preferred Stock, par value
        $0.01 per share with 52 shares issued and outstanding.

             (b) 130 shares of Series B Cumulative Preferred Stock, par value
        $0.01 per share, with 130 shares issued and outstanding.

             (c) 6,000 shares of Series C Cumulative Preferred Stock, par value
        $.01 per share, with 2,755 shares issued and outstanding.

     The Company formerly had 130 shares of Series A Preferred outstanding, and
used approximately $3.1 million of the proceeds of the subordinated debt
offering to redeem 78 of such shares. The remaining 52 shares of Series A
Preferred will remain outstanding subject to redemption as follows: one-half
(26) of such shares will be redeemed (at a redemption price of $1 million plus
accrued dividends, if any) on August 1, 2000 and the remainder will be redeemed
(at a redemption price of $1 million plus accrued dividends, if any) on August
1, 2001. Under the Company's Certificate of Incorporation (the "Certificate"),
holders of the outstanding nonvoting Series A Preferred are entitled to receive
cumulative cash dividends of $577 per share per quarter beginning August 1,
1998. Holders of Preferred A have the right to require the Company to redeem
Series A Preferred at an aggregate redemption price of $2 million plus accrued
dividends

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

(i) simultaneous with the occurrence of an "overall ownership shift," "employee
ownership shift" or "asset shift" (each as defined in the Certificate); or (ii)
within the 120 day period following an initial public offering of the Company's
equity securities. The Company may call the outstanding shares at any time at
the redemption price of $38,462 per share plus accrued dividends. As the
Preferred A carries a below market dividend rate of 6%, Aqua-Chem recorded the
Preferred A at a discount. Aqua-Chem is accreting the discount over the term of
the Series A Preferred with the accretion charged to retained earnings. The
carrying value, including accretion and dividends, of the Series A Preferred at
March 31, 1999 and December 31, 1997, is $1,839 and $4,594 respectively.

     Holders of the nonvoting Series B Cumulative Preferred Stock ("Preferred
B") are entitled to receive cumulative cash dividends of $1,538 per share per
year beginning August 1, 1997 payable at redemption. The redemption price of the
Preferred B shall be the "Normal Redemption Price," which shall generally be
based upon Aqua-Chem's Water Technologies' cumulative earnings before taxes for
the period 1997 through 2001. The redemption price is modified in the event that
prior to December 31, 2001, either (i) Water Technologies is sold to an
unrelated third party; or (ii) there occurs an initial public offering of the
Company's equity securities; or (iii) there occurs an "overall ownership shift,"
"employee ownership shift" or "asset shift" (each as defined in the
Certificate). The maximum redemption price, under any circumstance, shall be
$7,500. Holders of Preferred B generally shall have the right to require the
Company to redeem the Series Preferred B at the applicable redemption price plus
accrued dividends (i) simultaneous with the occurrence of an "overall ownership
shift" (as defined by the Certificate); (ii) within the 120 day period following
an initial public offering of Aqua-Chem's equity securities; (iii) within the
120 day period following a refinancing and retirement of the existing
subordinated debt; or (iv) July 31, 2004. The holders of the Series B Preferred
elected not to require that the Series B Preferred be redeemed in connection
with the subordinated debt offering. The carrying value of the Series B
Preferred is zero at March 31, 1999, as the redemption value is contingent upon
future events.

     Holders of Series C Preferred Stock are entitled to receive quarterly
dividends at the rate of 10.17% per year on the original issue price per share
($964) beginning on August 1,1997. Holders of Series C Preferred generally shall
have the right to require the Company to redeem all or any part of Series C
Preferred at a price equal to $1,000 per share, plus accrued dividends upon (i)
an "overall ownership shift,"employee ownership shift," or "asset shift" (each
as defined by the Certificate); (ii) within the 120-day period following an
initial public offering; or (iii) July 31, 2005. Any time after July 31, 2004,
the Company may call the outstanding shares at the redemption price of $1,000
per share plus accrued dividends. Holders of the Series C Preferred are entitled
to voting rights equivalent to the rights of one share of common stock. As the
redemption price of $1,000 per share exceeds the original issue price of $964,
Aqua-Chem recorded the Series C Preferred at a discount. Similar to the Series A
Preferred, the Company is accreting the discount over the term of the Series C
Preferred with the accretion charged to retained earnings. The carrying value,
including dividends, of the Series C Preferred at March 31, 1999 and December
31, 1997, is $3,105 and $2,771, respectively.

NOTE 11: STOCK OPTIONS

     Aqua-Chem has two stock option plans, the Aqua-Chem, Inc. 1997 Stock Option
Plan (as amended and restated, the "1997 Stock Option Plan") and the Aqua-Chem,
Inc. 1998 Stock Option Plan (the "1998 Stock Option Plan"). Aqua-Chem accounts
for these plans under APB Opinion No. 25.

     The 1997 Stock Option Plan provides for the granting to key employees, from
time to time, of non-statutory stock options to purchase up to an aggregate of
61,919 shares of Common Stock of Aqua-Chem at exercise prices to be determined
in accordance with the provisions of the 1997 Stock Option Plan. The 1997 Stock
Option Plan provides that between 10% and 20% of the aggregate number of shares
of Common Stock underlying each series of options shall vest each year on the
anniversary of the date of the grant, provided that in the prior fiscal year (i)
the option holder completed at least twelve consecutive months of service (as

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

defined in the 1997 Stock Option Plan), and (ii) the Company attained 80% to
100% of a specified target of EBITDA (as defined therein)($18.3 million in the
current year, subject to adjustment in the event of certain extraordinary
activities, (the "EBITDA Goal")). In the event that an installment does not vest
on an anniversary date because the EBITDA Goal is not met, such installment
shall vest on the next succeeding anniversary date as to which (i) the option
holder has completed at least twelve consecutive months of service, and (ii) the
Company met the EBITDA Goal by a cumulative amount greater than or equal to the
prior cumulative EBITDA shortfalls. Notwithstanding the foregoing, options
granted under the 1997 Stock Option Plan shall vest automatically on the seventh
anniversary of the date of the grant regardless of performance criteria. As of
March 31, 1999, there were 48,167 options granted at an exercise price of $3.75
per share under the 1997 Stock Option Plan.

     On August 4, 1998 the Board adopted the 1998 Stock Option Plan which
provides for the grant to key advisors, consultants, and employees, from time to
time, of non-statutory stock options to purchase up to an aggregate of 61,919
shares of Common Stock at exercise prices to be determined in accordance with
the provisions of the 1998 Stock Option Plan. Options granted under the 1998
Stock Option Plan shall vest on the seventh anniversary of the date of grant,
but may be accelerated subject to the terms of a written agreement entered into
between the Company and the optionee at the time of the grant. As of March 31,
1999, 15,740.40 shares at an exercise price of $5.00 share were granted.

     The option agreement for certain employees provide the opportunity for
accelerated vesting in the event of the achievement of certain Division goals.

     Under separate agreements from the 1997 Plan and the 1998 Plan, the option
to purchase 1,725 shares of common stock have been granted to two directors of
Aqua-Chem. Under the terms of the agreements, the option to purchase 600 shares
vests one year from the effective date of the grant, with the remaining 1,125
options vesting at a rate of 225 per year commencing on December 31, 1998 and
continuing through December 31, 2002. These options allow the holder to purchase
common stock of Aqua-Chem at $3.75 per share, which does not differ
significantly from fair market value. As of March 31, 1999, no options were
exercised.

     All options granted under the 1997 and 1998 Stock Option Plans were made
during the year ended March 31, 1999 at exercise prices that approximate fair
market value of the stock. Thus no compensation expense has been recorded by the
Company. None of the options are exercisable as of March 31, 1999 and no options
have been forfeited. The weighted-average exercise price was $4.05 at March 31,
1999 with a maximum term of ten years.

     The proforma effect of currently recognizing the fair market value of all
options granted is not material to the consolidated financial statements.

NOTE 12: COMMON STOCK PURCHASE WARRANTS

     The holders of the subordinated notes payable (see Note 9) also received
warrants, whereby they can acquire, at any time through July 31, 2007, in total,
176,471 shares of Aqua-Chem's common stock. The exercise price issuable upon
exercise of the warrants is $.01 per share of stock, with adjustments made to
prevent dilution in the event of any changes in capitalization of Aqua-Chem.

     After July 31, 2002, there are put and call features that may require
Aqua-Chem to purchase all or any part of the warrants or the common stock
obtained by the exercise of such warrants at the higher of a price determined in
the agreement or the fair market value of the Company's stock. During the year
ended March 31, 1999, no warrants were exercised.

     The warrants are recorded within other long-term liabilities at their
approximate fair value.

NOTE 13: EMPLOYEE BENEFIT PLANS AND POSTRETIREMENT BENEFITS

  Defined Benefit and Postretirement Benefit Plans

     Aqua-Chem maintains a defined benefit pension plan covering substantially
all union employees of the National Dynamics. The benefits are based on years of
service and the employee's compensation during the last five years of
employment. The Company's funding policy is to contribute amounts necessary to
satisfy the funding requirements as prescribed by laws and regulations. Plan
assets consist primarily of investments in investment-grade corporate loans with
maturities of five to ten years. Effective March 31, 1999, Aqua-Chem adopted
SFAS No. 132, "Employers Disclosures about Pensions and Other Postretirement
Benefits."

     Aqua-Chem maintains unfunded health care plans covering certain eligible
retirees and employees. The estimated costs of postretirement benefits,
principally health care, are accrued over the period the benefits are earned.
Aqua-Chem's policy is to fund postretirement benefits as incurred.

     The following assumptions were utilized in determining the funded status of
Aqua-Chem's defined benefit pension plan:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     As a result of the 1996 restructuring plan and the related early retirement
program, Aqua-Chem incurred a curtailment charge of $387, which is included in
the restructuring charges in the year ended December 31, 1996 consolidated
statement of operations.

     The weighted-average assumed health care cost trend rate used in
determining the March 31, 1999 and December 31, 1997 accumulated postretirement
benefit obligation was 7.5% for 1997 and 9% in 1999 declining 1% per year to
5.5% in 2002 and thereafter.

     Increasing the assumed health care cost trend rate by one percentage point
would increase the total accumulated postretirement benefit obligation as of
March 31, 1999, by approximately $300, and would increase the aggregate of the
service cost and interest cost components of the net postretirement benefit cost
by approximately $25 in fiscal 1999. Decreasing the assumed health care cost
trend rate by one percentage point would decrease the total accumulated
postretirement benefit obligation as of March 31, 1999, by approximately $75,
and would decrease the aggregate of the service cost and interest cost
components of the net postretirement benefit cost by approximately $20 in fiscal
1999.

     Aqua-Chem is also required to make payments to certain pension and employee
benefit funds, some of which are not controlled or administered by Aqua-Chem and
certain foreign subsidiary maintained government-mandated pension plans. Pension
expense of these plans for the year ended March 31, 1999, the three months ended
March 31, 1998, the period August 1 to December 31, 1997 and the period January
1 to July 31, 1997, and for the year ended December 31, 1996 was $365, $22,
$189, $140, and $266, respectively.

  Defined Contribution Plans

     Aqua-Chem maintains a defined contribution retirement plan which includes a
401(k) savings plan. Substantially all employees who are not members of
collective bargaining groups or employees of National Dynamics are eligible to
participate. Aqua-Chem's retirement contribution equals 4% of eligible
compensation while 401(k) contributions equal 50% of employee contributions to a
maximum Aqua-Chem contribution of 3%. Under provisions of the 401(k) savings
plan, employees may voluntarily contribute a maximum of 17% of eligible
compensation.

     Aqua-Chem also maintains a defined contribution retirement plan covering
substantially all nonunion employees of the Company's National Dynamics
Division. Participants may contribute up to 15% of their pay in pretax dollars.
The Company made a matching contribution of 50% of each participant's
contributions, up to 5% of pay since the date of the NDC Acquisition. This
discretionary matching contribution by the Company may vary from year to year.
Vesting in Company contributions is 100% after five years in the plan.

     For the year ended March 31, 1999, the three months ended March 31, 1998,
the period August 1, 1997 to December 31, 1997, the period January 1, 1997 to
July 31, 1997, and the year ended December 31, 1996, Aqua-Chem contributed
$1,767, $406, $675, $910 and $1,462, respectively, to these plans.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Aqua-Chem's reportable segments are strategic business units that offer
different products and services. They are managed differently as each business
requires different technology and marketing strategies. The Boiler segment
includes both the operating segments of Cleaver-Brooks and National Dynamics due
to their similarity in products and services, production processes, type of
customer, and the methods used to distribute their products.

     Aqua-Chem markets its products through a network of sales representatives,
distributors and an international direct sales force while maintaining
manufacturing facilities in the United States, Canada, and Mexico.

     Aqua-Chem does not have any customers who represent 10% or more of
consolidated sales.

NOTE 15: COMMITMENTS AND CONTINGENCIES

     Aqua-Chem and its subsidiaries are involved in legal proceedings, claims
and litigation arising in the ordinary course of business. These claims arise
from a variety of factors, including suits alleging personal injury related to
the use and exposure to certain of Aqua-Chem's products (see the "Legal
Proceedings" section of this Form 10-K for further information). The Company has
successfully resolved most closed claims and cases without payment and is
vigorously defending open claims, and believes that it has strong defenses to
all claims brought to date. Although Aqua-Chem believes the costs and
liabilities associated with these matters will not have a material adverse
effect on their results of operations or financial condition, there can be no
assurances to this effect.

     In the ordinary course of business, Aqua-Chem is contingently liable for
performance under letters of credit totaling approximately $3,700 and $3,900 at
March 31, 1999 and December 31, 1997. Management does not expect any material
losses to result from these off-balance sheet instruments, and, therefore,
values of these instruments at zero.

     Under the terms of the purchase agreement for the NDC Acquisition,
Aqua-Chem is contractually obligated to perform certain post-sale product work,
such as warranty, for pre-acquisition sales on behalf of the sellers. The costs
incurred by Aqua-Chem are billed to the sellers as the work is incurred. As of
March 31, 1999, Aqua-Chem had recorded a receivable from the sellers of $902 for
services performed which is included in other assets.

     As the sellers have retained the contractual liability for post-sale
product obligations for pre-acquisition sales, the accompanying consolidated
balance sheets do not reflect a liability for the future costs to be incurred by
Aqua-Chem for performance of their obligation under the terms of the purchase
agreement.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 16: EARNINGS (LOSS) PER SHARE

     At December 31, 1997, Aqua-Chem adopted SFAS No. 128, "Earnings per Share"
for all periods presented. The new standard simplified the computation of
earnings per share (EPS) and provides improved comparability with international
standards. SFAS No. 128 replaces primary EPS with "Basic" EPS, which excludes
dilution and is computed by dividing net earnings or (loss) by the
weighted-average number of common shares outstanding for the period. "Diluted"
EPS is computed similarly to primary EPS by reflecting the potential dilution
that occurs if securities or other contracts to issue common stock were
exercised or converted to common stock or resulted in the issuance of common
stock that then shared in the earnings. The following reconciles the numerators
and denominators of the basic and diluted earnings per share computations.

EMPLOYMENT AGREEMENTS

     The Company has employment agreements with all of the Executive Officers
currently employed by the Company except Ms. Chapman, Mr. Kettinger and Mr.
Thimm. Employment agreements for Ms. Chapman and Mr. Kettinger are currently
being negotiated but have not yet been finalized and executed. These agreements
govern the compensation, benefits and treatment upon termination under various
circumstances, including voluntary termination by either party or termination by
reason of retirement, death or disability.

     Compensation under these employment agreements includes a base salary plus
a bonus calculated under the Company's management incentive program as a
percentage of the executive's base salary. Each Named Executive Officer is
entitled to participate in all employee benefit plans made available to the
Company's senior executive officers, including, without limitation, medical,
disability, life insurance, retirement and management incentive plans. The
employment agreements for the Named Executive Officers provide for additional
benefits, such as club membership, vacation, auto allowance and supplemental
life insurance. The employment agreement of Mr. Norris provides for a bonus
calculated as a percentage of base salary (50%) in the event of a Change In
Control, as that term is defined in his employment agreement. In connection with
the Management Buy-Out, in July 1997 Mr. Norris was awarded a bonus of $50,000,
pursuant to such Change In Control provision. Mr. Barton, the Company's former
Vice President and Chief Financial Officer, Mr. Bruce Dickson, the Company's
former Vice President of Human Resources, and Mr. McNally, the Company's former
Executive Vice President and General Manager -- Cleaver-Brooks, also received
Change In Control bonuses of $150,000, $55,000 and $175,000, respectively. Mr.
Barton resigned February 19, 1999, Mr. Dickson died in April, 1998, and Mr.
McNally resigned on November 17, 1998. One-half of the amount of each Named
Executive Officer's Change In Control bonus was paid in August 1997 and is
reflected in the Summary Compensation Table under "All Other Compensation."
Payment of the remaining one-half was contingent upon continued employment with
Aqua-Chem for a period of six months following the Change In Control, was paid
to the Named Executive Officers on February 1, 1998 and is also reflected in the
Summary Compensation Table under "All Other Compensation."

     Each employment agreement continues indefinitely until terminated as
provided in the agreement, except for Mr. Miller's employment agreement which is
for a six year term expiring on July 31, 2003, unless

                                       56
<PAGE>   59

terminated prior to the end of such term as provided in the agreement. Each
employment agreement may be terminated by either the Company or the executive at
any time by giving notice as required under the agreement; provided, however,
that under certain conditions the executive may be entitled to certain severance
benefits as described in that executive's individual agreement. Each agreement
also imposes certain confidentiality obligations on the executive and places
restrictions on the executive's involvement in activities that may compete with
the Company and on engaging fellow employees both during employment and
following termination. Violation of such provisions, or other termination for
cause, as defined in the agreements, may result in forfeiture of severance and
other benefits that may otherwise accrue.

RETIREMENT AND SAVINGS PROGRAMS

     The Company maintains a defined contribution retirement plan which includes
a 401(k) savings plan. Substantially all employees who are not members of
collective bargaining groups are eligible to participate. The Company's
retirement contribution equals 4% of eligible compensation to certain employee
groups while 401(k) contributions equal 50% of employee contributions to a
maximum Company contribution of 3% of eligible compensation. Under provisions of
the 401(k) savings plan, employees may voluntarily contribute a maximum of 17%
of eligible compensation.

     In connection with the NDC Acquisition, the Company assumed the sponsorship
of the National Dynamics Corporation 401(k) Plan and the National Dynamics
Corporation Union Pension Plan that were previously maintained by NDC, for the
benefit of employees of the Company's National Dynamics Division.

     The Company also maintains employee incentive plans covering substantially
all employees who are not members of collective bargaining groups. The Company's
contribution to these plans is based upon defined levels of profitability.

     The Company maintains unfunded health care plans covering certain eligible
retirees and employees. The estimated costs of postretirement benefits,
principally health care, are accrued over the period the benefits are earned.
The Company's policy is to fund postretirement benefits as incurred.

MANAGEMENT INCENTIVE PLANS

     On November 15, 1996, the Company adopted the Aqua-Chem, Inc. Management
Incentive Plan (the "Management Incentive Plan").

     The Management Incentive Plan was implemented to provide an incentive to
motivate and reward key management eligible employees for achievement of
short-term results. The incentive payment to participants is calculated through
a formula that utilizes Return On Net Assets, or RONA (subject to adjustment in
the event of certain extraordinary charges, such as acquisitions, divestitures
and/or major new strategic initiatives) as the critical financial performance
measure. Participation is limited to selected senior level employees from each
of the business units and at the corporate level. An Administrative Committee is
responsible for administration of the Management Incentive Plan (including
selection of participants, setting individual incentive opportunity ranging from
10% to 100% of the participant's annual salary, setting financial targets, and
evaluation of performance), subject to the review and final approval of the
Compensation Committee of the Board.

STOCK OPTION PLANS

     In connection with the Management Buy-Out, the Company adopted the
Aqua-Chem, Inc. 1997 Stock Option Plan (as amended and restated, the "1997 Stock
Option Plan"), which provides for the grant to key employees, from time to time
of non-statutory stock options to purchase up to an aggregate of 61,919 shares
of Common Stock of Aqua-Chem at exercise prices to be determined in accordance
with the provisions of the 1997 Stock Option Plan. The 1997 Stock Option Plan
provides that between 10% and 20% of the aggregate number of shares of Common
Stock underlying each series of options shall vest each year on the anniversary
of the date of the grant, provided that in the prior fiscal year (i) the option
holder completed at least twelve consecutive Months of Service (as defined in
the 1997 Stock Option Plan), and (ii) the Company attained

                                       57
<PAGE>   60

80% to 100% of a specified target of EBITDA (as defined therein) ($18.3 million
in the current year, subject to adjustment in the event of certain extraordinary
activities, such as the NDC Acquisition (the "EBITDA Goal")). In the event that
an installment does not vest on an anniversary date because the EBITDA Goal is
not met, such installment shall vest on the next succeeding anniversary date as
to which (i) the option holder has completed at least twelve consecutive Months
of Service, and (ii) the Company met the EBITDA Goal by a cumulative amount
greater than or equal to the prior cumulative EBITDA shortfalls. Notwithstanding
the foregoing, options granted under the 1997 Stock Option Plan shall vest
automatically on the seventh anniversary of the date of the grant regardless of
performance criteria.

     On August 4, 1998 the Board adopted the Aqua-Chem, Inc. 1998 Stock Option
Plan (the "1998 Stock Option Plan") which provides for the grant to key
advisors, consultants and employees, from time to time, of non-statutory stock
options to purchase up to an aggregate of 61,919 shares of Common Stock at
exercise prices to be determined in accordance with the provisions of the 1998
Stock Option Plan. Options granted under the 1998 Stock Option Plan shall vest
on seventh anniversary of the date of grant, but may be accelerated subject to
the terms of a written agreement entered into between the Company and the
optionee at the time of the grant.

     The option agreement for certain employees provide the opportunity for
accelerated vesting in the event of the achievement of certain Division goals.

PHANTOM STOCK PLAN

     On January 23, 1998, the Board approved the Aqua-Chem, Inc. 1998 Phantom
Stock Plan (the "Phantom Stock Plan"), effective April 1, 1998.

     The objective of the Phantom Stock Plan is to provide certain senior level
executives and officers with the opportunity to share in future increases in the
value of the Company's Common Stock. The Board (or a committee appointed by the
Board) selects participants and determines the number of shares of phantom stock
to be awarded to each participant. Participants who remain employed by the
Company as of the scheduled payment dates (with certain exceptions) become
entitled to receive the value of their phantom stock awards for that year if a
specified percentage of the EBITDA goal (as specified in the Phantom Stock Plan)
is attained (90% in the current year, subject to decrease in future years). The
value of a participant's phantom stock is determined by multiplying the number
of shares of phantom stock initially awarded to the participant that year by the
value of a share of Common Stock determined in accordance with a formula set
forth the Phantom Stock Plan which is based a multiple of Actual EBITDA with
certain balance sheet adjustments. Two-thirds of the value of a participant's
phantom stock award is scheduled to be paid in the June following the end of the
period to which the award relates, with the remaining third to be paid in the
June of the subsequent year. Regardless of the foregoing, in the event that the
amount that would have been paid out at the end of the 1998 or 1999 calendar
years under the Executive Management Incentive Plan is greater than the amount
payable under the Phantom Stock Plan as of June immediately following the end of
the twelve-month period to which the award relates (i.e. two-thirds of the total
value of the award), then the participant shall be entitled to the amount that
would have been payable under the Executive Management Incentive Plan.

     Series A Preferred. The Company formerly had 130 shares of non-voting
Series A Preferred outstanding, and used approximately $3.1 million of the
proceeds of the subordinated bond offering to redeem 78 of such shares. The
remaining 52 shares of Series A Preferred will remain outstanding subject to
redemption as follows: one-half (26) of such shares will be redeemed (at a
redemption price of $1 million plus accrued dividends, if any) on August 1, 2000
and the remainder will be redeemed (at a redemption price of $1 million plus
accrued dividends, if any) on August 1, 2001. Under the Company's Certificate,
holders of the outstanding non-voting Series A Preferred are entitled to receive
cumulative cash dividends of $577 per share per quarter beginning August 1,
1998. Holders of the remaining Series A Preferred have the right to require the
Company to redeem Series A Preferred at an aggregate redemption price of $2
million plus accrued dividends (i) simultaneous with the occurrence of an
"overall ownership shift," "employee ownership shift," or "asset shift" (each as
defined in the Certificate); or (ii) within the 120-day period following an
initial public offering of the Company's equity securities. The Company may call
the outstanding Series A Preferred shares at any time at the redemption price of
$38,462 per share plus accrued dividends.

     Series B Preferred. Holders of the non-voting Series B Preferred are
entitled to receive cumulative cash dividends of approximately $1,538 per share
per year beginning August 1, 1997 payable at redemption. The redemption price of
Series B Preferred shall be the "Normal Redemption Price," which is generally
based upon Water Technologies' cumulative earnings before taxes for the period
1997 through 2001. The redemption price is modified in the event that prior to
December 31, 2001, either (i) Water Technologies is sold to an unrelated third
party; (ii) there occurs an initial public offering of the Company's equity
securities; or (iii) there occurs an "overall ownership shift," "employee
ownership shift" or "asset shift" (each as defined in the Certificate). The
maximum redemption price, under any circumstance, is $57,692 per share. Holders
of Series B Preferred generally have the right to require the Company to redeem
the Series B Preferred at the applicable redemption price plus accrued dividends
(i) simultaneous with the occurrence of an "overall ownership shift" (as defined
by the Certificate); (ii) within the 120-day period following an initial public
offering of the Company's equity securities; (iii) within the 120-day period
following a refinancing and retirement of the Existing Subordinated Debt; or
(iv) on July 31, 2004. Under certain circumstances the redemption of the Series
B Preferred could result in an event of default under the Indenture. The holders
of the Series B Preferred elected not to require that the Series B Preferred be
redeemed in connection with the subordinated bond offering.

     Series C Preferred. Holders of Series C Preferred are entitled to receive
quarterly dividends at the rate of 10.17% per year on the original issue price
per share ($964) beginning on August 1, 1997. Holders of Series C Preferred
generally shall have the right to require the Company to redeem all or any part
of Series C Preferred at a price equal to $1,000 per share, plus accrued
dividends (i) upon an "overall ownership shift," "employee ownership shift," or
"asset shift" (each as defined by the Certificate); (ii) within the 120-day
period following an initial public offering of the Company's equity securities;
or (iii) on July 31, 2005. Any time after July 31, 2004, the Company may call
the outstanding shares at the redemption price of $1,000 per share plus accrued
dividends, provided that the Series A Preferred and Series B Preferred have each
been redeemed. Each share of Series C Preferred has one vote per share,
equivalent to the voting rights of one share of Common.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

MANAGEMENT AGREEMENT

     The Company entered into an Interim Management Agreement ("Management
Agreement") with J. Miller Management, Inc. ("JMM") dated July 8, 1996, pursuant
to which the Company engaged JMM to

                                       61
<PAGE>   64

provide the services of Mr. Miller as the Company's President and Chief
Executive Officer. Mr. Miller is the President and co-owner of JMM. The
Management Agreement provided that Mr. Miller would serve as Interim Chief
Executive Officer, provide management services and expertise to the Company, and
manage the operations of the Company, commencing on July 8, 1996. The Management
Agreement was terminable at will by either party; however, if the Company were
to have terminated the Management Agreement without cause it would have been
liable for all compensation due thereunder. If the Company were to have
terminated the Management Agreement with cause (including Mr. Miller's failure
to obtain government security clearance) it would have been liable only for
accrued obligations through the date of termination.

     The Management Agreement was terminated on July 31, 1997 when Mr. Miller
became employed by, and entered into an employment agreement with, the Company
(see "Management -- Employment Agreements"). The total cost to the Company for
Mr. Miller's services under the Management Agreement for 1997 was approximately
$1,514,000, including incentive compensation of approximately $267,000 and a
Sale Bonus of $861,000. The total cost to the Company for Mr. Miller's services
under the Management Agreement for 1996 was approximately $286,000.
