                                     PART I

ITEM 1. BUSINESS

     NATCO Group Inc. (the Company) is a leading provider of wellhead equipment,
systems and services used in the production of oil and gas, primarily at or near
the wellhead, to separate oil and gas within a hydrocarbon stream and to remove
contaminants. Separation and decontamination at the wellhead are necessary to
meet the specifications of transporters and end users. These products and
services are used in onshore and offshore fields in most major oil and gas
producing regions in the world.

     The Company designs and manufactures a diverse line of production equipment
including: (1) separators, which separate a hydrocarbon stream into oil, gas and
water; (2) dehydration and desalting units, which remove water and salt from oil
and gas; (3) heaters, which prevent solids from forming in gas and reduce the
viscosity of oil; (4) gas conditioning units and membrane separation systems,
which remove carbon dioxide and other contaminants from a gas stream; (5) water
filtration systems, which remove oil and contaminants from water derived from
the production process; and (6) control systems, which monitor and control
production equipment.

     The Company was incorporated in Delaware during 1988 and in 1989 acquired
National Tank Company (NATCO) from Combustion Engineering, Inc. (C-E). The
Company acquired Total Engineering Services Team Inc. (TEST) in June 1997 from
Weatherford Enterra, Inc. and The Cynara Company (Cynara) in November 1998 from
a group of private investors.

     The Company's products and services are offered as either integrated
systems or individual components through four business segments: (1) traditional
production equipment and services, a segment which primarily provides
standardized components, replacement parts and used components and equipment
servicing; (2) engineered systems, a segment which primarily provides
customized, large scale integrated oil and gas production systems; (3)
instrumentation and electrical systems, a segment which provides control panels
and systems that monitor and control oil and gas production; and (4) Canadian
operations, a segment which provides traditional production equipment and
services and engineered systems.

TRADITIONAL PRODUCTION EQUIPMENT AND SERVICES

     Traditional production equipment and services consists of production
equipment, replacement parts, and used equipment refurbishing and servicing and
are sold primarily onshore in North America and in the Gulf of Mexico. The
equipment built for the North American oil and gas industry "off the shelf" or
in customized variations of standardized equipment requires limited engineering.
Traditional production equipment and services are marketed through 31 sales and
service centers in the United States, two in Canada and one in Venezuela.

     Traditional production equipment includes:

          Separators. Separators are used for the primary separation of a
     hydrocarbon stream into oil, water and gas. The separator product line
     includes: horizontal separators, which are used to separate hydrocarbon
     streams with large volumes of gas, liquids or foam; vertical separators,
     which are used to separate hydrocarbon streams containing contaminants
     including salt and wax; filter separators, which are used to remove
     particulate contaminants from gas streams; and Thermo Pak(TM) Units, which
     are used for the combined heating and separating of production in cold
     climates.

          Oil Dehydration Equipment. Oil dehydrators are used to remove water
     from oil. The oil dehydration product line includes: horizontal
     PERFORMAX(R) treaters, which separate oil and water mixtures using gravity
     and proprietary technology; Dual Polarity(R) electrostatic treaters, which
     dehydrate oil using high voltage electrical pulsation; vertical treaters,
     which optimize recovery of condensable, salable hydrocarbons; Vertical Flow
     Horizontal (VFH(TM)) processors, which combine the advantages of horizontal
     and vertical vessels to remove gas and water from oil streams; and
     heater-treaters, which use heat to accelerate the dehydration process.

                                        3
<PAGE>   4

          Heaters. Heaters are used to reduce the viscosity of oil to improve
     flow rates and to prevent hydrates from forming in the gas stream. The
     Company manufactures both indirect fired heaters and standardized and
     customized direct fired heaters. In each system, heat is transferred to the
     hydrocarbon stream through a medium such as water, water/glycol, steam,
     salt or flue gas. The heater product line includes: water bath heaters;
     vaporizers used to vaporize propane and other liquefied gases; salt bath
     heaters; steam bath heaters; and Controlled Heat Flux (CHF(TM)) heaters,
     which use combustion to create a heat transfer medium.

          Gas Conditioning Equipment. Gas conditioning equipment removes
     contaminants from gas streams. Gas conditioning equipment includes: glycol
     dehydration equipment, which exposes gas streams to glycol in order to
     remove water vapor; amine systems, which use amine to remove acidic gases
     such as hydrogen sulfide and carbon dioxide from gas streams; conditioning
     equipment used to remove hydrogen sulfide from gas; Glymine(R) units, which
     combine the effects of glycol equipment and amine systems; the
     BTEX-Buster(R), which virtually eliminates the emissions of volatile
     hydrocarbons associated with glycol dehydration reboilers; and Desi-Dri(R)
     Systems, which use highly compressed drying agents to remove water vapor
     from gas streams.

          Gas Processing Equipment. The Company offers standard and custom
     processing equipment for the extraction of liquid hydrocarbons to meet feed
     gas and liquid product requirements. The Company manufactures several
     standard mechanical refrigeration units for the recovery of salable
     hydrocarbon liquids from gas streams. Low Temperature Extractor (LTX(R))
     units are mechanical separation systems designed for handling high-pressure
     gas at the wellhead. These systems remove liquid hydrocarbons from gas
     streams more efficiently and economically than other methods.

          Water Treatment Equipment. The Company designs and manufactures water
     treatment and conditioning equipment for the removal of contaminants from
     water extracted in oil and gas production. Oil producers use our
     PERFORMAX(R) Matrix Plate Coalescer in primary separators of oil and water
     and final skimming. Flow splitters remove gases from an oil-water
     dispersion, separate oil and water and discharge the oil and/or emulsion
     through controllable outlets.

          Equipment Refurbishment. The Company sources, refurbishes and
     integrates used oil and gas production equipment. Customers that purchase
     this equipment enjoy reduced delivery times and lower equipment costs
     relative to new equipment. The used equipment market is focused primarily
     in North America, both onshore and offshore, although we have observed a
     growing interest internationally. The Company has entered into agreements
     with major and large independent oil companies in both the United States
     and Canada to evaluate, track and refurbish used production equipment and
     may act as a broker between another oil company and our customer or may
     purchase, refurbish and sell used equipment to our customers. The Company
     believes that it has one of the largest databases in the North American oil
     and gas industry of available surplus production equipment. This database,
     coupled with the Company's extensive refurbishing facilities and
     experience, enables the Company to respond to customer requests for
     refurbished equipment quickly and efficiently.

          Parts, Service and Training. The Company provides replacement parts
     for our own equipment and for equipment manufactured by others. Each branch
     of our marketing network also serves as a local parts and service business.
     The Company has service employees stationed in some branches of Wilson
     Supply Company and National-Oilwell, Inc. The Company also offers
     operational and safety training to the oil and gas production industry and
     uses training programs as a marketing tool for our other products and
     services.

ENGINEERED SYSTEMS

     The Company designs, engineers and manufactures these systems for large
production development projects throughout the world. The Company also provides
start-up services for our engineered products. Engineered systems typically
require a significant amount of technology, engineering and project management.

                                        4
<PAGE>   5

     Engineered systems are marketed through direct sales forces based in
Houston, Calgary, London, Tokyo, Kuala Lumpur and Caracas, augmented by
independent representatives in other countries. The Company also uses the unique
oil testing capabilities at its research and development facility to market
engineered systems. This capability enables the Company to determine equipment
specifications that best suit customers' requirements. Engineered systems
include:

     Integrated Oil and Gas Processing Trains. These consist of multiple units
that process oil and gas from primary separation through contaminant removal.
For example, the Company designed, manufactured and assembled a module for a
production facility situated off the coast of West Africa that is capable of
processing 20,000 barrels of oil, 4,000 barrels of water and 24 million standard
cubic feet of gas per day. Also, the Company designed, manufactured and
installed process systems for BP Exploration (Alaska), Inc.'s Badami development
on the North Slope of Alaska and its Northstar development, also located on the
North Slope.

     Floating Production Systems. These consist of large skid-mounted processing
units used in conjunction with semi-submersible, converted tankers and other
floating production vessels. Floating production equipment must be specially
designed to overcome the detrimental effects of wave motion on floating vessels.
The Company pioneered and patented the first wave-motion production vessel
internal system and continues to advance this technology at its research and
development facility using a wave-motion table, which simulates a variety of sea
states.

     Dehydration and Desalting Systems. Dehydration and desalting involves the
removal of water and salt from an oil stream. Desalting is a specialized form of
dehydration. In this process, water is injected into an oil stream to dissolve
the salt and the saltwater is then removed from the stream. Large production
projects often use electrostatic technology to desalt oil. The Company believes
that it is the leading developer of electrostatic technologies for oil treating
and desalting.

     One of the Company's dehydration and desalting systems, the Electro
Dynamic(TM) Desalter, can be used in oil refineries, where stringent desalting
requirements have grown increasingly important. These requirements have
increased as crude quality has declined and catalysts have become more sensitive
and sophisticated, requiring lower levels of contaminants. The reduced number of
vessels employed by this system is particularly important in refinery
applications where space is at a premium.

     Large Gas Processing Facilities. The Company provides large gas processing
facilities for the separation, heating, dehydration and removal of liquids and
contaminants to produce pipeline or liquefaction-quality gas. The Company also
designs, manufactures and, in some cases, operates gas-processing facilities
that remove carbon dioxide from gas streams. These facilities use Cynara's
membrane technology, which provides the most cost-effective separation solution
for gas streams containing more than 20% carbon dioxide. A primary market for
this application is production from gas wells, such as those located in
Southeast Asia, which have high levels of naturally occurring carbon dioxide.
Another market is production from wells, such as those located in West Texas, in
which carbon dioxide injection is used to enhance the recovery of oil and gas
reserves.

     Downstream Facilities. The Company offers several technologies that have
crossover applications in the refinery and petrochemical sectors. Most involve
aspects of oil treating and water treating. We discussed above the use in
refineries of one of our dehydration and desalting systems. In addition, the
Company can provide DOX(TM) units to ethylene processors that clean both heavy
and light dispersed oil from water.

NATCO CANADA

     NATCO Canada provides a combination of traditional production equipment and
services and engineered systems to oil and gas producers in Western Canada. Most
production equipment manufactured by NATCO Canada is similar in design and
purpose to that built in the U.S. with modifications to operate in a cold
weather environment. Periodically, NATCO Canada engineering and manufacturing
capacity is drawn upon to assist in our engineered systems projects.

INSTRUMENTATION AND ELECTRICAL SYSTEMS

     The primary market for instrumentation and electrical systems is in
offshore applications throughout the world. The Company markets and services
these products through a four-branch network primarily located in the Gulf Coast
area. These instrumentation and electrical systems include:

     Control Systems. The Company designs, assembles and installs pneumatic,
hydraulic, electrical and computerized control panels and systems. These systems
monitor and change key parameters of oil and gas production systems. Key
parameters include wellhead flow control and emergency shutdown of production
and safety systems. A control system consists of a control panel and related
tubing, wiring, sensors and connections.

     Engineering and Field Services. The Company provides start-up support,
testing, maintenance, repair, renovation, expansion and upgrade of control
systems including those designed or installed by competitors. Company design and
engineering staff also provide contract electrical engineering services.

     SCADA Systems. Supervisory control and data acquisition (SCADA) systems
provide remote monitoring and control of equipment, production facilities,
pipelines and compressors via radio, cellular phone, microwave and satellite
communication links. SCADA systems reduce the number of personnel and frequency
of site visits, and allow for continued production during periods of emergency
evacuation, thereby reducing operating costs.

     For a discussion of summarized financial information concerning the
Company's reportable segments and operations by geographical region for the year
ended December 31, 1999, the nine months ended December 31, 1998 and the year
ended March 31, 1998, see Note 20 of Notes to Consolidated Financial Statements.

MARKET ISSUES

     Demand for oil and gas production equipment and services is driven
primarily by the following: (1) levels of production of oil and gas in response
to worldwide demand; (2) the discovery of new oil and gas fields; (3) the
changing production profiles of existing fields (meaning the mix of oil, gas and
water in the hydrocarbon stream and the level of contaminants); and (4) the
quality of new hydrocarbon production.

     Generally, oil and gas exploration and production companies reduce
exploration and development activity during periods of weak oil prices and
demand and increase this activity during periods of strong oil prices and
demand. The extent to which the revenues of the industry increase depends upon
the success of the exploration efforts. In general, these revenue increases lag
expansion of exploration and development capital budgets in times of recovery in
the oil and gas industry. These lag times can be up to several years in offshore
operations but are generally shorter for onshore operations.

     Changing production profiles in existing fields also increase the demand
for products and services in the industry. As existing fields are reworked or
enhanced recovery methods are employed, additional and more complex equipment
may be required to produce oil and gas from these fields. This can result from
changes in the mix of oil and gas produced by the field or an increase in water,
carbon dioxide or other naturally occurring contaminants or as the result of
enhanced recovery techniques. In addition, many new oil and gas fields contain
lower quality hydrocarbon streams that require more complex production
equipment. Examples include carbon dioxide rich formations in West Texas and
Southeast Asia and heavy crude in Western Canada and in the Orinoco Delta in
Venezuela.

CUSTOMER RELATIONSHIPS

     The Company has devoted a considerable portion of its marketing time and
effort to develop and maintain relationships with key customers. Some of these
relationships are project-specific, such as the Company's participation as an
"alliance" partner with BP Amoco in several Alaskan projects, or with Mobil in
the development of its Chinook platform in the Gulf of Mexico. In other
instances, the Company is a preferred supplier for products and services to key
customers in particular equipment lines or over large geographic

                                        6
<PAGE>   7

areas. Examples of this preferred supplier role include the Company's
relationships with BP Amoco, UPR, Sonat Exploration, Chevron Canada, Mobil Oil
Canada and Renaissance.

COMPETITION

     Contracts for the Company's products and services are generally awarded on
a competitive basis and competition is intense. The most important factors
considered by customers in awarding contracts include the availability and
capabilities of equipment, the ability to meet the customer's delivery schedule,
price, reputation, experience and safety record.

     Historically, the existence of overcapacity in the industry has caused
increased price competition in many areas of the business. In addition, the
Company may encounter obstacles in its international operations that impair its
ability to compete in individual countries. These obstacles may include: (1)
subsidies granted in favor of local companies; (2) taxes, import duties and fees
imposed on foreign operators; (3) lower wage rates in foreign countries; and (4)
fluctuations in the exchange value of the United States dollar compared with the
local currency. Any or all these factors could adversely affect the Company's
ability to compete and thus adversely affect its results of operations.

     The Company's primary competitors in the Traditional Production Equipment
and Services business segment are the Smith division of Hanover Compressor
Corp., as well as numerous privately held, mainly regionalized companies. The
primary competitors in the Engineered Systems business segment, are Baker Hughes
Process Systems, a division of Baker Hughes, Kvaerner Process Systems, and
numerous engineering and construction firms. The primary competitors in the
Instrumentation and Electrical Systems business segment are Onix Systems, Inc.
and numerous privately held companies.

     The Company's management believes that the Company is one of the largest
oil and gas surface production equipment providers in North America and that its
size, research and development capabilities, brand names and marketing
organization provide the Company with a competitive advantage over other
participants in the industry.

"Liquidity and Capital Resources" at "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

RESEARCH AND DEVELOPMENT

     The Company considers itself a leader in the development of oil and gas
industry production equipment technology, and pioneered many of the original
separation technologies for converting unprocessed hydrocarbon fluids into
salable oil and gas. The Company has developed: (1) the first high capacity oil
and gas separator; (2) the first emulsion treating system; (3) Dual Polarity(TM)
electrostatic oil treaters; (4) DOX(TM) and OSX(TM) water filtration systems;
(5) high pressure indirect heaters; and (6) PERFORMAX(R) oil and water treating
systems.

     The Company's wave-motion compensating separator has become the industry
standard for floating production applications, and its electrostatic oil
treating technology is the most advanced in the industry. As of December 31,
1999, the Company held 60 active U.S. patents and a number of related foreign
patents. The Company also has an application pending for one additional U.S.
patent. In addition, the Company is licensed under seven patents held by others.

     The Company operates a research and development facility in Tulsa,
Oklahoma, at which a number of test devices are used to simulate and analyze oil
and gas production processes. The Company also operates a manufacturing facility
in Pittsburgh, California where active research and development efforts are
ongoing in the area of membrane technology. At February 29, 2000, the Company
had approximately 14 employees engaged in research and development activities.
For information regarding the amounts of research and development expense for
the year ended December 31, 1999, the nine months ended December 31, 1998, and

INTERNATIONAL OPERATIONS

     The Company operates its business and markets its products and services
throughout the world and therefore is subject to the risks customarily attendant
to international operations and investments in foreign countries. These risks
include: nationalization, expropriation, war and civil disturbances, restrictive
actions by local governments, limitations on repatriation of earnings, changes
in foreign tax laws, and changes in currency exchange rates. The occurrence of
any of these risks could have an adverse effect on regional demand for the
Company's products and services and its ability to provide them. An interruption
of the Company's international operations could have a material adverse effect
on the Company's results of operations and financial condition.

     Portions of the Company's sales are made in Southeast Asia. The currencies
of several countries in Southeast Asia underwent significant devaluations
against the United States dollar in 1997 and early 1998. The devaluation of
these currencies and the related consequences to the economies in these
countries has adversely affected economic growth in the region. Exposure to the
devaluation of foreign currencies is partially mitigated as the Company
primarily invoices its customers with amounts denominated in United States
dollars. To the extent the economies of countries in Southeast Asia continue to
be adversely affected, no assurance can be given that the demand for the
Company's products and services in the region will continue at historical or
anticipated levels.

EMPLOYEES

     At December 31, 1999, the Company had approximately 1,226 employees as
compared to approximately 1,508 at December 31, 1998 and approximately 1,470
employees at March 31, 1998. Approximately 109 employees at December 31, 1999
were represented under collective bargaining agreements that extend through July
2001. The Company believes that its relationships with its employees are
satisfactory.

ENVIRONMENTAL MATTERS

     The Company is subject to environmental regulation by federal, state and
local authorities in the United States and in several foreign countries.
Although the Company believes that it is in substantial compliance with all
applicable environmental laws, rules, and regulations ("laws"), the field of
environmental regulation can change rapidly with the enactment or enhancement of
laws and stepped up enforcement of these laws, either of which could require the
Company to change or discontinue certain business activities. At present, the
Company is not involved in any material environmental matters of any nature and
is not aware of any material environmental matters threatened against it.

ITEM 2. PROPERTIES

     The Company operates 5 primary manufacturing plants ranging in size from
approximately 6,400 square feet to approximately 116,000 square feet of
manufacturing space. The Company also owns and leases distribution and service
centers, sales offices, and warehouses. The Company leases its corporate
headquarters in Houston, Texas. At December 31, 1999, the Company owned or
leased approximately 780,000 square feet of facility, of which approximately
408,000 square feet was leased and approximately 372,000 square feet was owned.
Of this total square footage, approximately 614,000 square feet was located in
the United States, approximately 151,000 square feet was located in Canada, and
approximately 15,000 square feet was located in other international areas.

     The following chart summarizes the number of facilities owned or leased by
the Company by geographic region and business segment:

ITEM 3. LEGAL PROCEEDINGS

     The Company is a party to various routine legal proceedings that are
incidental to its business activities. The Company insures against the risk of
these proceedings to the extent deemed prudent by its management, but the
Company offers no assurance that the type or value of this insurance will meet
the liabilities that may arise from any pending or future legal proceedings
related to its business activities. The Company does not, however, believe the
pending legal proceedings, individually or taken together, will have a material
adverse effect on its results of operations or financial condition.

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

     No matters were submitted to a vote of security holders during the year.

                                    PART II

ITEM 5.MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCK HOLDER MATTERS

     The Company's authorized common stock consists of 45,000,000 shares of
Class A common stock and 5,000,000 shares of Class B common stock. There were
14,147,374 Class A shares and 471,739 Class B shares outstanding as of March 15,
2000. The approximate number of record holders of the Company's Class A shares
and Class B shares was 36 and 7, respectively, at March 15, 2000. There were
500,000 authorized preferred shares at March 15, 2000, of which none was issued.
The Company's Class A common stock is traded on the New York Stock Exchange
under the ticker symbol NTG. There was no public market for the stock prior to
January 28, 2000. High and low sales prices for the Company's Class A common
stock on the New York Stock Exchange for the period January 28, 2000 (first
trade after effective date) to March 15, 2000, were $14.94 to $10.00,
respectively. The closing price of the Company's Class A common stock on March
15, 2000 was $12.06.

     The Company does not intend to declare or pay any dividends on its common
stock in the foreseeable future, but intends to retain any future earnings for
use in the business. Currently, the Company's bank credit facilities restrict
the amount of dividends and other distributions that its operating subsidiaries
may remit to the Company. Since the Company is a holding company, these
restrictions have the practical effect of precluding the Company from paying
dividends on its common stock.

(1) In June 1997, the Company distributed its investment in Process Technology
    Holdings, Inc. (PTH) to its then sole stockholder in a tax-free transaction.
    In accordance with generally accepted accounting principles, the Company
    accounted for the results of operations of PTH as discontinued operations
    for all periods presented. Accordingly, the net income of PTH is excluded
    from income (loss) from continuing operations in the statement of operations
    data for the periods presented.

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

     The following discussion of the Company's historical results of operations
and financial condition should be read in conjunction with the Company's
consolidated financial statements and notes thereto.

                                       10
<PAGE>   11

OVERVIEW

     The Company's operations are organized into four separate business
segments: traditional production equipment and services, a segment which
primarily provides standardized components, replacement parts and used
components and equipment servicing; engineered systems, a segment which
primarily provides customized, large scale integrated oil and gas production
systems; Canadian operations, a segment which combines traditional production
equipment and services and engineered systems; and instrumentation and
electrical control systems, a segment which provides control panels and systems
that monitor and control oil and gas production.

     The Company recognizes revenues from significant contracts (contracts
greater than $250,000 and longer than four months in duration) and all
instrumentation and electrical contracts and orders on the percentage of
completion method. The Company records revenues and profits on other sales as
shipments are made. Earned revenue is based on the percentage that costs
incurred to date bear to total estimated costs. If estimated total costs on any
contract or work-in-process indicate a loss, the Company recognizes the entire
loss immediately. The Company generally recognizes revenue and earnings to which
the percentage of completion method applies over a period of two to six
quarters. Customers typically retain an interest in uncompleted projects.

FORWARD-LOOKING STATEMENTS

     "Management's Discussion and Analysis of Financial Condition and Results of
Operations" includes forward-looking statements within the meaning of Section
27A of the Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended (each a "Forward-Looking Statement"). The words
"believes," "expects," "plans," "intends," "estimates," "projects," "will,"
"could," "may" and similar expressions are intended to identify forward-looking
statements. The Company's expectations about its business outlook, customer
spending, oil and gas prices and the business environment for the Company and
the industry in general are only its expectations regarding these matters. No
assurance can be given that actual results may not differ materially from those
in the forward-looking statements herein for reasons including, but not limited
to: market factors such as pricing and demand for petroleum related products,
the level of petroleum industry exploration and production expenditures, the
effects of competition, world economic conditions, the level of drilling
activity, the legislative environment in the United States and other countries,
policies of the Organization of Petroleum Exporting Countries (OPEC), conflict
in major petroleum producing or consuming regions, the development of technology
which could lower overall exploration and development costs, weather patterns
and the overall condition of capital and equity markets for countries in which
the Company operates.

INDUSTRY AND BUSINESS ENVIRONMENT

     The Company provides oilfield service equipment for the oil and gas
industry. During late 1998 and throughout 1999, this industry suffered a
downturn that resulted in a significant decline in overall drilling and
production expenditures by oil and gas operators due to low hydrocarbon prices.
The Company's business is closely linked to the market conditions of its
customers. When production slows, fewer purchases are made of the Company's
products, especially traditional production equipment and services, which
comprised approximately 32% and 35% of the Company's revenues for the years
ended December 31, 1999 and December 31, 1998, respectively. However, trends
toward higher oil prices have been indicated during the latter part of 1999 and
into the first quarter of 2000. For example, the price of West Texas
Intermediate crude oil has increased to approximately $26.00 per barrel for
March 2000, as compared to $10.00 per barrel at March 1999. Furthermore, as of
March 22, 2000, crude oil futures on the New York Mercantile Exchange were
trading at $28.00 per barrel for April 2000 delivery. Although these crude oil
price increases are indicators that additional oil and gas production may occur
during 2000, there can be no assurance that overall production will increase or
that an increase in production trends will continue throughout 2000 or that such
an increase in production would result in an increase in revenues for the
Company.

TWELVE MONTHS ENDED DECEMBER 31, 1999 COMPARED TO TWELVE MONTHS ENDED DECEMBER

     Revenues. Revenues for the year ended December 31, 1999 decreased $30.9
million, or 15%, to $169.9 million from $200.8 million for the year ended
December 31, 1998. Revenues generated in 1999 included $22.1 million of revenue
attributed to Cynara, which the Company acquired in November 1998. Excluding the
impact of Cynara for 1999, the Company's revenues would have declined $53.0
million, or 26% in 1999 compared to 1998. This overall decline in revenue was
attributable to the significant reduction in spending by the Company's customers
as a result of the sharp decrease in energy prices that began in mid-1998 and
continued until early 1999.

</TABLE>

     The increase in revenues for engineered systems for the year ended December
31, 1999, of $14.4 million, or 32%, relates primarily to the acquisition of
Cynara, as twelve months of operations were included in the 1999 results versus
only one month of operations during 1998. Revenues of $60.0 million and $45.6
million for the years ended December 31, 1999 and December 31, 1998,
respectively, include affiliated revenues of $1.7 million and $1.5 million.

     Traditional equipment and service revenues decreased $15.9 million, or 22%,
due to an overall decline in the oil and gas industry during the fourth quarter
of 1998 and throughout 1999. This decline is consistent with the reduction in
the number of drilling rigs operating in the United States; operating rigs
decreased from 826 at December 31, 1998 to 625 at December 31, 1999. Affiliated
revenues for this business segment were $1.2 million and $0.7 million for the
years ended December 31, 1999 and December 31, 1998, respectively.

     Revenues for instrumentation and electrical systems decreased $4.7 million,
or 10%, for 1999 as compared to 1998, due to the completion of a significant
project during 1998. Included in revenues of $41.8 million and $46.6 million for
the years ended December 31, 1999 and December 31, 1998, are affiliated revenues
of $2.3 million and $1.1 million, respectively.

     The decrease in revenues for NATCO Canada for the year ended December 31,
1999 as compared to the year ended December 31, 1998, of $23.7 million, is due
primarily to the overall decline in the oil and gas industry and the completion
of significant projects during 1998. Total revenues of $19.8 million for the
year ended December 31, 1999 include $1.5 million of revenue from affiliates.
Revenues of $43.5 million for the year ended December 31, 1998, include $2.5
million of affiliate revenues.

     The change in revenues for corporate and other represents the elimination
of revenues of affiliates as discussed above.

     Gross Profit. Gross profit for the year ended December 31, 1999 increased
$1.6 million, or 4%, to $42.3 million, compared to $40.7 million for the year
ended December 31, 1998. As a percentage of revenue, gross margins improved to
25% for the year ended December 31, 1999 from 20% for the year ended December
31, 1998. The margin improvement was attributable partially to the inclusion of
Cynara's results in 1999, as well as an improved product mix due to the sharp
decline in revenue from NATCO Canada, which historically has generated lower
margins.

</TABLE>

     Gross profit for the year ended December 31, 1999 for engineered systems
increased $8.5 million, or 102%, primarily due to the contribution of $9.2
million from Cynara, included in the 1999 results, as compared to $0.4 million
contributed by Cynara for the one month of operations included in the 1998
results. Gross margin for this business segment represented 28% and 18% of sales
for engineered systems for the years ended December 31, 1999 and December 31,
1998, respectively.

     The decrease of $4.1 million, or 23%, in gross profit for the traditional
equipment and services business segment for the year ended December 31, 1999 as
compared to the respective period in 1998, is due to a 22% decline in revenues.
As a percentage of revenue, gross margins were 25% and 25%, respectively, for
the years then ended.

     The increase in gross profit for the instrumentation and electrical systems
business segment for the year ended December 31, 1999 as compared to the year
ended December 31, 1998, is the result of improved efficiency for completed
projects in 1999 and due to the completion of a high margin project in Venezuela
during the second quarter of 1999. Gross margin as a percentage of revenue for
the years ended December 31, 1999 and December 31, 1998 was 21% and 19%,
respectively.

     Gross profit for the year ended December 31, 1999 for NATCO Canada
decreased $2.9 million, or 48%, to $3.1 million, compared to $6.0 million for
the year ended December 31, 1998. Gross profit decreased due to a 55% decline in
revenue during the same period. As a percentage of revenue, gross margin was 16%
for 1999 compared to 14% for 1998.

     Selling, General and Administrative Expense. Selling, general and
administrative expense increased $0.5 million, or 2%, to $32.4 million for the
year ended December 31, 1999 compared to $31.9 million reported for the year
ended December 31, 1998. Overall, expenses were reduced in the United States and
Canada, due to a downturn in the industry. These expense reductions were offset,
however, due to the addition of Cynara, which provided $1.9 million for the year
ended December 31, 1999. In addition, during 1999 the Company recorded
non-recurring costs of $0.4 million primarily associated with the retirement of
an officer and $0.6 million related to the purchase by the Company of stock
options previously granted to the Chief Executive Officer of the Company. Also
in 1999, the Company revised previous estimates related to the remaining costs
associated with the closure of NATCO (UK) Ltd., and reversed these related
accruals.

     Depreciation and Amortization Expense. Depreciation and amortization
expense for the year ended December 1999 increased $2.8 million, or 147%, to
$4.7 million compared to $1.9 million for the year ended December 31, 1998. This
increase is due primarily to the addition of Cynara, which contributed $3.0
million of depreciation and amortization expense for the year ended December 31,
1999.

     Interest Expense. Interest expense was $3.3 million for the year ended
December 31, 1999 as compared to $2.9 million for the year ended December 31,
1998. This 14% increase in interest expense was due primarily to an increase in
debt as a result of the acquisition of Cynara in November 1998, partially offset
by debt repayments throughout 1999.

     Interest Cost on Postretirement Benefit Liability. Interest cost on
postretirement benefit liability remained constant on a year-to-year basis.

     Revaluation Gain on Postretirement Benefit Liability. The revaluation gain
on postretirement benefit liability increased $1.1 million from a loss of $0.1
million for the year ended December 31, 1998, to a gain of $1.0 million for 1999
primarily due to a decrease in the liability for postretirement benefits. This
liability decreased during 1999 as a result of an increase in the discount rate
(from 6.75% to 8.0%) used to calculate the net present value of this liability.
In addition, the Company experienced favorable claim experience, partially
offset by an unfavorable increase in medical trend rates for the year ended
December 31, 1999.

     Provision (Benefit) for Income Taxes. Income tax expense increased $0.9
million, or 150%, from $0.6 million for the year ended December 31, 1998, as
compared to $1.5 million for the year ended December 31, 1999. This increase is
due to the following: (1) higher state income tax due to a greater percentage of
revenues for 1999, as compared to 1998, contributed by TEST, whose manufacturing
facilities are located in the state of Louisiana; (2) an increase in permanent
book-to-tax differences due to the non-deductibility of goodwill amortization
related to the Cynara acquisition made in November 1998; and (3) a one-time
charge of $0.3 million incurred as a deferred state rate adjustment which
resulted when a former holding company was liquidated and the resulting assets
were transferred to an entity with a lower effective tax rate for deferred tax
assets.

     Income from Continuing Operations. Income from continuing operations
decreased from $2.6 million for the year ended December 31, 1998, to $0.6
million for the year ended December 31, 1999. Pursuant to the above discussion,
contributing factors include: an increase in selling, general and administrative
expense of $0.5 million; an increase in depreciation and amortization expense of
$2.8 million; an increase in net interest expense of $0.3 million; and an
increase in provision for income taxes of $0.9 million, partially offset by an
increase in gross profit of $1.6 million and a $1.1 million increase in the gain
from the revaluation of postretirement benefit liability.

     Net Income. Net income for the year ended December 31, 1999 decreased to
$0.6 million compared to $2.6 million reported for the year ended December 31,
1998. The decrease was due to the various factors discussed above.

     TWELVE MONTHS ENDED DECEMBER 31, 1998 COMPARED TO TWELVE MONTHS ENDED

     Revenues. Revenues for the year ended December 31, 1998 increased $18.4
million, or 10%, to $200.8 million from $182.4 million for the year ended
December 31, 1997. The increase was principally attributable to the inclusion of
TEST for the full year in 1998 as compared to six months for 1997. The increase
was also attributable to the inclusion of Cynara revenue for five weeks in 1998.
Excluding the impact of the acquisitions, revenues would have declined $7.0
million, or 4%, from 1998 to 1997. The decline in revenue in 1998 compared to
1997 was attributable to the reduction in spending by the Company's customers as
a result of the decrease in energy prices that began in mid-1998 and continued
until early 1999.

     Revenues for engineered systems for the year ended December 31, 1998
increased $8.9 million, or 24%, as compared with the year ended December 31,
1997, inclusive of revenues from affiliates of $1.5 million and $0.7 million for
the respective periods. This increase is largely due to the completion of
projects in 1998 that were awarded to the Company in 1997.

     Traditional production and equipment and services revenue decreased only
$1.6 million, or 2%, for the year ended December 31, 1998 as compared to the
year ended December 31, 1997, which includes an increase in affiliated revenues
of $0.1 million, from $0.7 million to $0.6 million for the respective periods.
These results are principally due to a strong order backlog carried into 1998.

     Revenues for instrumentation and electrical systems for the year ended
December 31, 1998 increased $24.7 million, or 113%, to $46.6 million from $21.9
million for the year ended December 31, 1997, inclusive of revenues from
affiliates of $1.1 million for 1998. No revenues from affiliates were recorded
for 1997. This increase is principally attributable to the inclusion of TEST for
the full year in 1998 as compared to six months in 1997.

     NATCO Canada revenues for 1998 decreased by $11.2 million, or 21%, to $43.5
million from $54.7 million for 1997. This change is net of an increase in
affiliated revenues of $0.4 million, from $2.5 million for the year ended
December 31, 1998 to $2.1 million for the year ended December 31, 1997. This
decrease in revenue was attributable to a significant decline in spending levels
by our customers as a result of low energy prices, and the completion of a large
project in the first six months of 1998.

     The change in revenues for corporate and other represents the elimination
of revenues of affiliates as discussed above.

     Gross profit. Gross profit for the year ended December 31, 1998 increased
$5.2 million, or 15%, to $40.7 million from $35.6 million from the year ended
December 31, 1997. As a percentage of revenue, gross margin improved to 20% for
1998 versus 19% for 1997. The margin improvement was attributable to improved
performance for engineered systems projects as well as an improved product mix
due to the decline in revenue from NATCO Canada, which historically has
generated lower margins.

     Gross profit for engineered systems increased $3.9 million, or 87%, to $8.4
million for the twelve months ended December 31, 1998, from $4.5 million for the
twelve months ended December 31, 1997. The increase was partially due to the
inclusion of Cynara in the 1998 results. Additionally, improved project
management and selectivity in the bid and acceptance process contributed to
higher gross margins. As a percentage of revenue, gross margins were 18% for
1998 compared to 12% for 1997.

     Gross profit for traditional production equipment and services decreased
$1.1 million, or 6%, for 1998 as compared to 1997. This decrease was primarily
due to the 2% reduction in revenue during the same time period. As a percentage
of revenue, gross margins were 25% for 1998 compared with 26% for 1997.

gross margins remained constant at 19% for the twelve months ended December 31,
1998 and the twelve months ended December 31, 1997.

     Gross profit for NATCO Canada decreased $2.4 million, or 29%, to $6.0
million from $8.4 million. The decrease is principally attributable to a 21%
reduction in revenues for the same period of time. As a percentage of revenue,
gross margins were 14% for 1998 compared to 15% in 1997.

     Selling, General and Administrative Expense. Selling, general and
administrative expense increased $3.7 million, or 13%, to $31.9 million for the
twelve months ended December 31, 1998 as compared to $28.2 million for the
twelve months ended December 31, 1997. This increase was primarily due to the
inclusion of TEST for the full year in 1998 compared to only six months in 1997,
as well as the inclusion of Cynara for five weeks in 1998. In addition,
non-recurring expenses totaling $1.6 million were recorded in 1998, of which
$1.2 million related to a previous initial public offering effort in early 1998,
and $0.4 million related to severance costs incurred. In addition, insurance
reserve reductions totaling $2.5 million were recorded in 1998, reflecting
revisions to previous estimates related to workers compensation and general
liability claims. In 1997, the Company incurred non-recurring compensation
expense related to the conversion of stock appreciation rights into stock
options totaling $1.2 million.

     Depreciation and Amortization Expense. Depreciation and amortization
expense increased $0.8 million, or 73%, to $1.9 million from $1.1 million for
the twelve months ended December 31, 1997. This increase was principally due to
goodwill amortization related to the TEST acquisition and depreciation of Cynara
gas processing plants.

     Interest Expense. Interest expense decreased $0.2 million, or 6%, to $2.9
million from $3.1 million for the twelve months ended December 31, 1997. This 6%
decrease in interest expense was due primarily to the conversion of 13%
subordinated notes into common stock by the Company's principal stockholders on
April 1, 1998.

     Interest Cost on Postretirement Benefit Liability. Interest cost on
postretirement benefit liability remained constant on a year-to-year basis.

     Revaluation Loss on Postretirement Benefit Liability. Revaluation loss
decreased by $0.1 million, or 50%, from $0.2 million for the twelve months ended
December 31, 1997 to $0.1 million for the twelve months ended December 31, 1998.
This resulted from slight changes in the actuarial assumptions.

     Provision (Benefit) for Income Taxes. Income tax expense decreased $0.3
million, or 33%, from $0.9 million for the year ended December 31, 1997, as
compared to $0.6 million for the year ended December 31, 1998. This decrease is
primarily due to a lower contribution of income from continuing operations from
foreign affiliates for 1998 when compared to 1997. Tax rates on income derived
from foreign affiliates are typically higher than domestic rates.

     Income from Continuing Operations. Income from continuing operations for
1998 increased $1.5 million, or 136%, to $2.6 million from $1.1 million for the
respective period in 1997. This increase was due primarily to a $5.2 million
increase in gross profit (largely due to an increase in revenues) and a $0.3
million decrease in provision for income taxes, less a $0.8 million increase in
depreciation and amortization expense and a $3.7 million increase in selling,
general and administrative expense.

     Income from Discontinued Operations. Income from discontinued operations of
$0.8 million for the year ended December 31, 1997 represented income from PTH,
the capital stock of which was distributed in June 1997 to the Company's sole
stockholder. There was no income from discontinued operations for the year ended
December 31, 1998.

     Net Income. Net income for the twelve months ended December 31, 1998
increased $0.7 million, or 37%, to $2.6 million from $1.9 million for the twelve
months ended December 31, 1997. The decrease was due to the various factors
discussed above.

FISCAL YEAR ENDED MARCH 31, 1998 COMPARED TO FISCAL YEAR ENDED MARCH 31, 1997

     Revenues. Revenues for the fiscal year ended March 31, 1998 increased by
$75.3 million, or 59%, to $202.0 million from $126.7 million for the fiscal year
ended March 31, 1997. Of this increase, $32.7 million was attributable to the
inclusion of the results of TEST in the Company's results for the last nine
months of the fiscal year ended March 31, 1998. In addition, the Company had
revenues of $27.7 million from the BP Exploration (Alaska), Inc. alliance
project compared to revenues of only $4.5 million from such alliance for the
fiscal year ended March 31, 1997.

</TABLE>

     Revenues for engineered systems for fiscal 1998 decreased by $9.4 million,
or 22%, to $34.2 million from $43.6 million for fiscal 1997 inclusive of revenue
from affiliates of $0.8 million for the year ended March 31, 1998 and $0.9
million for the year ended March 31, 1997. The decrease in revenues resulted
primarily from the postponement of a major project and increased selectivity in
the bid process.

     Revenues for traditional production equipment and services for fiscal 1998
increased by $19.9 million, or 35%, to $76.8 million from $56.9 million for
fiscal 1997 inclusive of revenue from affiliates of $0.6 million for the year
ended March 31, 1998 and $1.1 million for the year ended March 31, 1997. The
increase in revenues resulted primarily from strong demand in the market for
these products and services.

     Revenues for instrumentation and electrical systems of $33.2 million was
attributable to the inclusion of TEST revenues for nine months of the fiscal
year ended March 31, 1998. These results include revenue from affiliates of $0.5
million for the year ended March 31, 1998.

     Revenues for NATCO Canada, for fiscal 1998, increased by $27.7 million, or
87%, to $59.7 million compared to $32.0 million for fiscal 1997. No revenues
from affiliates are included in the fiscal year 1998 results, as compared to
$3.9 million of affiliate revenues included for fiscal 1997. A significant
portion of the increase in overall revenues for NATCO Canada was due to a
substantial project for BP Exploration (Alaska), Inc.

     The change in revenues for corporate and other represents the elimination
of revenues of affiliates as discussed above.

     Gross Profit. Gross profit for fiscal 1998, increased $14.3 million, or
55%, to $40.2 million from $25.9 million for fiscal 1997 primarily due to the
increases in revenues discussed above. As a percentage of revenues, gross
profits remained unchanged for fiscal 1998 compared to fiscal 1997.

</TABLE>

     Gross profit for engineered systems for fiscal 1998 decreased $0.8 million,
or 13%, to $5.2 million from $6.0 million for fiscal 1997, primarily due to the
decrease in revenue discussed above. As a percentage of revenues, gross profit
increased from 14% for fiscal 1997 to 15% for fiscal 1998.

     Gross profit for traditional production equipment and services for fiscal
1998 increased $5.1 million, or 35%, to $19.6 million from $14.5 million for
fiscal 1997 primarily due to the increases in revenue discussed above. As a
percentage of revenues, gross profit remained constant at 25% for fiscal years
1998 and 1999.

     Gross profit for instrumentation and electrical systems of $6.4 million for
fiscal 1998 was attributable to the inclusion of gross profit for TEST for the
nine months ended March 31, 1998.

     Gross profit for NATCO Canada for fiscal 1998 increased by $3.6 million, or
69%, to $9.0 million from $5.4 million for fiscal 1997 primarily due to the
increase in revenue discussed above. As a percentage of revenues, gross profit
decreased from 17% for fiscal 1997 to 15% for fiscal 1998, primarily as a result
of a lower margin on the BP Exploration (Alaska), Inc. project.

     Selling, General and Administrative Expense. Selling, general and
administrative expense increased $5.2 million, or 22%, to $28.5 million for
fiscal 1998 from $23.3 million for fiscal 1997. Of this increase, $4.7 million
was attributable to the inclusion of the results of TEST, and the remainder was
primarily attributable to increased expenses associated with the increase in
volume in the Company's business. In addition, insurance reserve reductions
totaling $1.3 million were recorded during the year ended March 31, 1998,
reflecting revisions to previous estimates related to workers compensation and
general liability claims. For the year ended March 31, 1997, non-recurring
compensation expense related to the conversion of stock appreciation rights into
stock options totaling $1.2 million was recorded.

     Depreciation and Amortization Expense. Depreciation and amortization
expense increased $0.5 million, or 53%, to $1.3 million for fiscal 1998 from
$0.9 million for fiscal 1997. Of the $0.5 million increase in fiscal 1998, $0.4
million related to depreciation and amortization expense at TEST.

     Interest Expense. Interest expense increased by $1.1 million, or 58%, to
$3.0 million for fiscal 1998 from $1.9 million for fiscal 1997, primarily as a
result of increased debt incurred in connection with the acquisition of TEST.

     Interest Cost on Postretirement Benefit Liability. Interest cost on
postretirement benefit liability increased $0.1 million, or 10%, to $1.0 million
for fiscal 1998 from $0.9 million for fiscal 1997 due to increased amortization
resulting from an upward revaluation of the postretirement benefit liability
based on revised actuarial assumptions at March 31, 1997.

     Revaluation Loss on Postretirement Benefit Liability. Revaluation of
postretirement benefit liability decreased $1.3 million, or 87%, from $1.5
million for fiscal 1997 to $0.2 million for fiscal 1998. This resulted primarily
from a decrease in the discount rate used in the actuarial calculations.

     Provision (Benefit) for Income Taxes. Income tax expense increased $1.8
million, from a benefit of $0.7 million for the fiscal year ended March 31, 1997
to expense of $1.1 million for the fiscal year ended

                                       19
<PAGE>   20

March 31, 1998. This change is due primarily to a loss from continuing
operations for the fiscal year ended March 31, 1997, associated with
expenditures for the closing of the NATCO UK office in London. In addition, the
effective tax rate for fiscal 1998 was 18%, which reflects the benefit of net
operating losses carried forward from prior years.

     Income (Loss) from Continuing Operations. Income from continuing operations
increased $7.0 million to $5.1 million for fiscal 1998 from a loss of $1.8
million for fiscal 1997, primarily as a result of increases in gross profit and
the inclusion of operations of TEST for the nine months ended March 31, 1998.

     Income from Discontinued Operations. Income from discontinued operations of
$0.8 million for the year ended March 31, 1998 and $1.1 million for the year
ended March 31, 1997 represented income from PTH, the capital stock of which was
distributed in June 1997 to the Company's sole stockholder.

     Net Income. Net income increased by $1.9 million, or 46%, to $5.9 million
for fiscal 1998 from $4.1 million for fiscal 1997 primarily as a result of the
factors discussed above.

LIQUIDITY AND CAPITAL RESOURCES

     As of February 29, 2000, the Company had cash and working capital of $10.9
million and $37.4 million, respectively, as compared to cash and working capital
of $1.7 million and $25.3 million at December 31, 1999. This increase in cash
reflects funds received pursuant to an initial public offering of the Company's
Class A common stock, less debt repayments made during February 2000, as further
discussed below.

     Net cash provided by (used in) operating activities for the year ended
December 31, 1999, the nine months ended December 31, 1998 and the year ended
March 31, 1998 was $15.4 million, ($1.5) million and $3.1 million, respectively.
This increase in net cash provided by operating activities in 1999 is primarily
due to a reduction of order backlog, which is consistent with the decrease in
trade accounts receivable related to percentage of completion projects from $9.3
million at December 31, 1998 to $0.9 million at December 31, 1999. Furthermore,
the acquisition of Cynara in November 1998 supplied additional working capital
cash flow in 1999 as compared to 1998.

     Net cash used in investing activities for the year ended December 31, 1999,
the nine months ended December 31, 1998 and the year ended March 31, 1998 was
$2.6 million, $17.1 million and $24.7 million, respectively. The Company's
primary use of funds for the nine months ended December 31, 1998 was the
acquisition of Cynara, which required the use of $15.5 million of cash. The
Company's primary use of funds for the year ended March 31, 1998 was the
acquisition of TEST, which required the use of $22.4 million of cash.

     Net cash provided by (used in) financing activities for the year ended
December 31, 1999, the nine months ended December 31, 1998 and the year ended
March 31, 1998 was ($13.7) million, $20.2 million and $21.7 million,
respectively. The use of cash for financing activities during 1999 is due
primarily to the repayment of long-term debt. Cash provided by financing
activities for the nine months ended December 31, 1998 and the year ended March
31, 1998, relates to issuances of common stock and borrowings of long-term debt
to finance the Cynara and TEST acquisitions, respectively.

     The Company maintains revolving credit and term loan facilities as well as
a working capital facility for export sales. The revolving credit facility
provides for up to $22.0 million of borrowings in the United States and up to
$10.0 million of borrowings in Canada, subject to borrowing base limitations. As
of December 31, 1999, there were no borrowings outstanding under the revolving
credit facility. In addition, the Company had issued $2.5 million of letters of
credit under the revolving facility as of December 31, 1999. The initial term
loan of $32.5 million had been reduced to $31.2 million as of December 31, 1999.
Borrowings under the revolving credit facility mature in November 2001, and the
term loan matures in November 2003. The revolving credit and term facility is
secured by substantially all of the Company's assets. The export sales credit
facility provides for aggregate borrowings of $10.0 million, subject to
borrowing base limitations, of which no borrowings were outstanding as of
December 31, 1999. In addition, the Company had issued letters

                                       20
<PAGE>   21

of credit totaling $7.3 million under the export facility. The export sales
credit facility is secured by specific project inventory and receivables, and is
partially guaranteed by the EXIM Bank. The export sales credit facility loans
mature in July 2002. As of December 31, 1999, the weighted average interest rate
of the Company's borrowings under these credit facilities was 8.98%.

     On January 24, 2000, the Company invested $5.4 million in cash to purchase
Porta-Test, Inc., financed through cash on hand, borrowing under the revolving
credit facility and the issuance of a one-year promissory note of approximately
$0.7 million. The Company's management believes that this acquisition will allow
the Company to provide oil and gas producers with production facilities that are
smaller and more efficient. Porta-Test, Inc. will be included in the NATCO
Canada business segment during the first quarter of 2000. The purchase price
allocation for this acquisition has not yet been finalized.

     On February 2, 2000, the Company received funds from an initial public
offering of its Class A common stock totaling $37.7 million. This offering
became effective on January 27, 2000. On February 7, 2000, the Company received
proceeds of $10.5 million from the underwriters of its initial public offering
as the underwriter executed an over-allotment option for the Company's Class A
common stock.

     On February 8, 2000, the Company purchased Modular Production Equipment,
Inc. for $2.5 million in cash and a promissory note of $0.3 million. The
Company's management believes that with the water treatment technology and
expertise of Modular Production Equipment, Inc., the Company can offer its
customers an advanced and complete turnkey process solution. This acquisition
will be included in the engineered systems business segment during the first
quarter of 2000. The purchase price allocation for this acquisition has not yet
been finalized.

     During February 2000, proceeds from the Company's initial public offering
were used to pay down the revolving credit facility by $25.9 million, including
$3.0 million borrowed to finance the purchase of Porta-Test, Inc. The
outstanding debt balance as of February 29, 2000 was $5.7 million.

     The Company estimates that cash generated from operations through 2000 will
be sufficient to meet its cash operating requirements. The Company's capital
expenditures generally consist of renovations and expansions of manufacturing
plants, technological improvements to management information systems and
acquisitions of, and improvements to, other equipment used in the business.
Historically, these capital expenditures have ranged from $1.0 million to $2.0
million annually. Budgeted capital expenditures for the year ending December 31,
2000 are approximately $3.5 million. This capital expenditure budget includes a
project to upgrade the existing membrane manufacturing facility in Pittsburgh,
California.

     The Company's sales backlog at February 29, 2000 and February 28, 1999 was
$83.5 million and $34.9 million, respectively. A significant percentage of the
February 29, 2000 backlog is represented by a contract with one customer,
Carigali-Triton Operating Company SDN BHD (CTOC). The CTOC contract was awarded
during June 1999, and is projected to generate total revenues of approximately
$73.0 million. During 1999, CTOC revenues of $14.6 million represented 9% of
total revenues for the Company. Revenues from the CTOC project for fiscal 2000
are expected to constitute a significant percentage of total revenue. Backlog at
February 29, 2000, excluding the CTOC project reflects a substantial decline
from backlog volumes as of the prior year. The Company's management anticipates
that the backlog at December 31, 2000, excluding the CTOC project, will be
substantially higher than the backlog at February 29, 2000 due to bookings that
are expected to occur during fiscal 2000.

     At February 29, 2000, borrowing base limitations reduced the Company's
available borrowing capacity under the revolving credit agreement to $19.1
million. However, the Company's management believes that the Company's operating
cash flow, supported by its borrowing capacity, will be adequate to fund
operations throughout 2000. Should the Company decide to pursue one or more
additional acquisition opportunities during 2000, the determination of the
Company's ability to finance these acquisitions will be a critical element of
the analysis of the opportunities.

INFLATION AND CHANGES IN PRICES

     The costs of materials (e.g., steel) for our products rise and fall with
their value in the commodity markets. Generally, increases in raw materials and
labor costs are passed on to our customers.

RECENT ACCOUNTING PRONOUNCEMENTS

     Statement of Financial Accounting Standards No. 133, Accounting for
Derivative Instruments and Hedging Activities, was issued by the Financial
Accounting Standards Board in June 1998. SFAS 133 standardizes the accounting
for derivative instruments, including derivative instruments embedded in other
contracts. Under the standard, entities are required to carry all derivative
instruments in the statement of financial position at fair value. The accounting
for changes in the fair value (i.e., gains or losses) of a derivative instrument
depends on whether it has been designated and qualifies as part of a hedging
relationship and, if so, on the reason for holding it. If specified conditions
are met, entities may elect to designate a derivative instrument as a hedge of
exposures to changes in fair values, cash flows, or foreign currencies. If the
hedged exposure is a fair value exposure, the gain or loss on the derivative
instrument is recognized in earnings in the period of change together with the
offsetting loss or gain on the hedged item attributable to the risk being
hedged. If the hedged exposure is a cash flow exposure, the effective portion of
the gain or loss on the derivative instrument is reported initially as a
component of other comprehensive income (outside earnings) and subsequently
reclassified into earnings when the forecasted transaction affects earnings. Any
amounts excluded from the assessment of hedge effectiveness, as well as the
ineffective portion of the gain or loss, is reported in earnings immediately.
Accounting for foreign currency hedges is similar to the accounting for fair
value and cash flow hedges. If the derivative instrument is not designated as a
hedge, the gain or loss is recognized in earnings in the period of change.

     The Company will adopt SFAS 133 for the fiscal year beginning January 1,
2001. The Company's management has not determined the impact that SFAS 133 will

ITEM 7.A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

EXCHANGE RATE SENSITIVITY

     The Company's operations are conducted around the world in a number of
different countries. Accordingly, future earnings are exposed to changes in
foreign currency exchange rates when transactions are denominated in currencies
other than the Company's functional currencies. These are the primary currencies
in which the Company conducts its business in various jurisdictions. The
majority of our foreign currency transactions are denominated in the Canadian
dollar, which is the functional currency of NATCO Canada. As these contracts are
denominated and settled in the functional currency, risks associated with
currency fluctuations are minimized. The Company does not currently hedge
against foreign currency translation risks and believes that foreign currency
exchange risk is not significant to our operations.

INTEREST RATE SENSITIVITY

     The Company's financial instruments subject to changes in interest rates
include its revolving credit and term loan facility and its working capital
facility for export sales. At December 31, 1999, the Company had $31.2 million
outstanding under the term loan portion of the revolving credit and term loan
facility. The term borrowings mature in November 2003 and bear interest at
floating rates. As of December 31, 1999, the weighted average interest rate of
the Company's borrowings under this credit facility was 8.98%. There were no
borrowings outstanding under the revolving credit portion or the working capital
facility at December 31, 1999.

     Based on past market movements and reasonably possible, near-term market
movements, the Company does not believe that potential, near-term losses in
future earnings, fair values, or cash flows from changes in interest rates are
likely to be material. Assuming the Company's current level of borrowings, a 100
basis point increase in interest rates under these borrowings would decrease the
Company's current year net income and

                                       22

cash flow from operations by less than $0.1 million. In the event of an adverse
change in interest rates, the Company could take action to mitigate its
exposure. However, due to the uncertainty of actions that could be taken and the
possible effects, this analysis assumes no such actions. Furthermore, this
analysis does not consider the effects of a possible change in the level of
overall economic activity that could exist in such an environment.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
NATCO Group Inc.:

     We have audited the accompanying consolidated balance sheets of NATCO Group
Inc., and subsidiaries as of December 31, 1999 and December 31, 1998 and the
related consolidated statements of operations, stockholders' equity and
comprehensive income, and cash flows for the year ended December 31, 1999, the
nine months ended December 31, 1998, and the year ended March 31, 1998. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 NATCO Group
Inc. and subsidiaries as of December 31, 1999 and December 31, 1998 and the
results of their operations and their cash flows for the year ended December 31,
1999, the nine months ended December 31, 1998, and the year ended March 31, 1998
in conformity with generally accepted accounting principles.

                       NATCO GROUP INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                             (DOLLARS IN THOUSANDS)

(1) ORGANIZATION

     NATCO Group Inc. (the Company) was formed in June 1988 by Capricorn
Investors, L.P. (Capricorn). Capricorn led a group of investors who invested
sufficient funds in the Company to enable the Company to acquire several
businesses from Combustion Engineering, Inc. (C-E). On June 21, 1989, the
Company acquired from C-E all of the outstanding common stock of W. S. Tyler,
Incorporated (Tyler), and National Tank Company (NATCO), and the net assets of
certain foreign affiliates of the Company. The accompanying consolidated
financial statements and all related disclosures include the results of
operations of the Company and its majority-owned subsidiaries for the year ended
December 31, 1999, the nine months ended December 31, 1998 and the year ended
March 31, 1998.

     During 1992, the Company contributed its common stock investment in Tyler
and $5,500 in cash to Process Technology Holdings, Inc. (PTH) in exchange for
all of the issued and outstanding common stock of PTH. In 1992 and 1993, PTH and
the Company sold certain shares of PTH common stock to third parties and, during
1997, the Company completed a tax-free spin-off of PTH to its stockholder. The
results of operations of PTH are shown as discontinued operations in the
consolidated statements of operations.

     On June 30, 1997, NATCO acquired Total Engineering Services Team, Inc.
(TEST), and on November 20, 1998, NATCO acquired The Cynara Company (Cynara).

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Fiscal Year Change. Effective April 1, 1998, the Company changed its fiscal
year end from March 31 to December 31.

     Principles of Consolidation. The consolidated financial statements include
the accounts of the Company and all of its majority-owned subsidiaries.
Significant intercompany accounts and transactions have been eliminated in
consolidation.

     Concentration of Credit Risk. Concentrations of credit risk with respect to
trade receivables are limited due to the large number of customers comprising
the Company's customer base and their geographic dispersion. No single customer
represented more than 10% of revenues for the year ended December 31, 1999 or
the nine months ended December 31, 1998. For the year ended March 31, 1998, the
Company had one customer that represented 14% of revenues for the year.

     Cash Equivalents. The Company considers all highly liquid investment
instruments with original maturities of three months or less to be cash
equivalents.

     Restricted Cash. At December 31, 1998 cash in the amount of $883 was
pledged as collateral on outstanding letters of credit related to performance
and warranty guarantees, and was classified as restricted cash on the balance
sheet. No restricted cash exists at December 31, 1999.

     Inventories. Inventories are stated at the lower of cost or market. Cost is
determined using the last in, first out (LIFO) method for NATCO domestic
inventories, average cost for TEST inventories and the first in, first out
(FIFO) method for all other inventories.

     Property, Plant and Equipment. Property, plant and equipment are stated at
cost less an allowance for depreciation. Depreciation on plant and equipment is
calculated using the straight-line method over the estimated useful lives.
Maintenance and repair costs are expensed as incurred; renewals and betterments
are capitalized. Upon the sale or retirement of properties, the accounts are
relieved of the cost and the related accumulated depreciation, and any resulting
profit or loss is included in income. The carrying values of property, plant and
equipment by location are reviewed annually and more often if there are
indications that these assets may be impaired.

                                       29

     Goodwill. Goodwill is being amortized on a straight-line basis over periods
of 20 and 40 years. The Company assesses the recoverability of this intangible
asset by determining whether the amortization over its remaining life can be
recovered through undiscounted future operating cash flows. Based on its most
recent analysis, the Company believes that no material impairment of goodwill
exists at December 31, 1999. Amortization expense for the year ended December
31, 1999, the nine months ended December 31, 1998, and the year ended March 31,
1998 was $739, $167, and $128, respectively. Accumulated amortization at
December 31, 1999 and December 31, 1998 was $1,133 and $394, respectively.

     Other Assets, Net. Other assets consist of prepaid pension assets, deposits
of a long-term nature, deferred financing costs and covenants not to compete.
Deferred financing costs and covenants not to compete have been capitalized and
are being amortized over the term of the related agreements. Amortization
expense for the year ended December 31, 1999, the nine months ended December 31,
1998, and the year ended March 31, 1998 was $570, $244, and $262, respectively.

     Environmental Remediation Costs. The Company accrues environmental
remediation costs based on estimates of known environmental remediation
exposure. Such accruals are recorded when the cost of remediation is probable
and estimable, even if significant uncertainties exist over the ultimate cost of
the remediation. Ongoing environmental compliance costs, including maintenance
and monitoring costs, are expensed as incurred.

     Revenue Recognition. Revenues from significant contracts (NATCO contracts
greater than $250 and longer than four months in duration and all TEST contracts
and orders) are recognized on the percentage of completion method. Earned
revenue is based on the percentage that incurred costs to date bear to total
estimated costs after giving effect to the most recent estimates of total cost.
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 claims and
change order revenues, if any. Losses expected to be incurred on jobs in
progress, after consideration of estimated minimum recoveries from claims and
change orders, are charged to income as soon as such losses are known. Customers
typically retain an interest in uncompleted projects. Other revenues and related
costs are recognized when products are shipped or services are rendered to the
customer.

     Stock-Based Compensation. Statement of Financial Accounting Standards
(SFAS) No. 123, "Accounting for Stock-Based Compensation," permits entities to
recognize as expense over the vesting period the fair value of all stock-based
awards on the date of grant. Alternatively, SFAS No. 123 also allows entities to
continue to apply the provisions of Accounting Principles Board (APB) Opinion
No. 25 and provide pro forma net income and pro forma earnings per share
disclosures for employee stock option grants made in 1995 and future years as if
the fair-value-based method defined in SFAS No. 123 had been applied. The
Company has elected to continue to apply the provision of APB Opinion No. 25 and
provide the pro forma disclosure provisions of SFAS No. 123.

     Research and Development. Research and development costs are charged to
operations in the year incurred. The cost of equipment used in research and
development activities, which has alternative uses, is capitalized as equipment
and not treated as an expense of the period. Such equipment is depreciated over
estimated lives of 5 to 10 years. Research and development expenses totaled
$1,898, $1,001, and $738 for the year ended December 31, 1999, the nine months
ended December 31, 1998, and the year ended March 31, 1998, respectively.

     Warranty Costs. Estimated future warranty obligations related to products
are charged to cost of goods sold in the period in which the related revenue is
recognized. Additionally, the Company provides some of its customers with
letters of credit covering potential warranty claims. At December 31, 1999 and
December 31, 1998, the Company had $1,798 and $2,528, respectively, in
outstanding letters of credit related to warranties.

     Income Taxes. Deferred tax assets and liabilities are recognized for future
tax consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. 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.

                                       30
<PAGE>   31

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, management 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 future generation of taxable income during the periods in
which those temporary differences become deductible. Management has considered
the scheduled reversal of deferred tax liabilities, projected future taxable
income and tax planning strategies in making this assessment.

     Translation of Foreign Currencies. Financial statement amounts related to
foreign operations are translated into their United States dollar equivalents at
exchange rates as follows: (1) balance sheet accounts at year-end exchange
rates, and (2) statement of operations accounts at the weighted average exchange
rates for the period. The gains or losses resulting from such translations are
deferred and included in accumulated other comprehensive loss as a separate
component of stockholders' equity. Gains or losses from foreign currency
transactions are reflected in the consolidated statements of operations.

     Use of Estimates. Management of the Company has made a number of estimates
and assumptions relating to the reported amounts of assets and liabilities and
the disclosure of contingent assets and liabilities and the amounts of revenues
and expenses recognized during the period to prepare these financial statements
in conformity with generally accepted accounting principles. Actual results
could differ from those estimates.

     Earnings per Common Share. In February 1997, the Financial Accounting
Standards Board (FASB) issued SFAS No. 128, Earnings per Share, which replaced
primary and fully diluted earnings per share with basic and diluted earnings per
share. The Company adopted the provisions of SFAS No. 128 in the fourth quarter
of 1997 and all previously reported earnings per share data have been restated.
Under SFAS No. 128, the basic earnings per share calculation excludes the
dilutive effect of common stock equivalents in determining basic earnings per
share. The diluted earnings per common and common equivalent share are computed
by dividing net income by the weighted average number of common and common
equivalent shares outstanding. For the purposes of this calculation, outstanding
employee stock options are considered common stock equivalents. In conformity
with Securities and Exchange Commission requirements, common stock, options and
warrants, or other potentially dilutive instruments which have been issued for
nominal consideration during the periods covered by income statements presented,
are reflected in earnings per share calculations for all periods presented.

     The following table presents earnings per common share amounts computed
using SFAS 128:

(3) CAPITAL STOCK

     Common Stock. On June 25, 1997, the Board of Directors of the Company
approved an increase in the number of authorized common shares from 3,000 to
20,000,000. On that date, the directors declared a 7,503 for one common stock
split to be effected by the distribution of 7,502 additional shares for each
share of common stock held by stockholders of record as of that date. On March
6, 1998, the Company's charter was amended to increase the number of authorized
shares of capital shares from 20,000,000 to 55,000,000, of which 5,000,000 are
shares of preferred stock, par value $0.01, and 50,000,000 are shares of common
stock. On that date, the board of directors declared a common stock split to be
effected by the exchange of four shares for every three shares of common stock
outstanding. All share data has been restated to reflect the effects of this
transaction.

     On November 18, 1998, the Company's charter was again amended to divide the
common stock into two classes: Class A common stock (45,000,000 shares) and
Class B common stock (5,000,000 shares). The two classes of common stock have
the same relative rights and preferences except the holders of the Class B
common stock have the right, voting separately as a class,

     - To elect one member of the Company's board of directors; and

     - To vote on any amendment to the Company's charter that would authorize
       additional Class B common stock or would adversely affect their right to
       elect a director.

Class B shares may be converted by the holder to Class A shares at any time, and
will automatically convert to Class A shares on January 1, 2002.

(4) ACQUISITIONS

     On June 30, 1997, NATCO completed the acquisition of TEST from Weatherford
Enterra, Inc. for $22,475 in cash. The funds used for the acquisition of TEST
were provided by $10,640 in additional equity and a $2,360 loan from Capricorn
Investors II, L.P. (Capricorn II) and proceeds from a new senior credit
facility.

     The acquisition has been accounted for as a purchase and the results of
TEST have been included in the consolidated financial statements since the date
of the acquisition. The purchase agreement allowed for purchase price
adjustments and included a guarantee of collectibility for TEST accounts
receivable acquired at the purchase price date. The Company subsequently
received cash of $1,387 and $1,690 related to purchase price adjustments and the
reimbursement of uncollected accounts receivable of TEST, respectively, at the
end of the purchase price adjustment period. Goodwill amounted to $6,237 and is
being amortized over a forty-year period.

     On November 20, 1998, the Company completed the acquisition of Cynara from
a group of private investors for $5,250 in cash, the assumption of $10,118 in
Cynara bank debt, and the issuance of 500,000 shares of NATCO Class B common
stock valued at $5,250. In addition, the Company may be required to issue up to
an additional 1,400,000 shares to Cynara's former shareholders based on
performance criteria defined in the purchase agreement. The Company had placed
450,000 shares in escrow related to this provision. The Company has issued
325,836 of these escrowed shares at December 31, 1999 and could be required to
issue up to an additional 950,000 shares at March 31, 2000 and December 31,
2000. Should additional shares be issued, a corresponding increase will be made
to cost in excess of fair value of net assets acquired. The funds used for the
acquisition of Cynara were provided by $5,300 in additional equity and proceeds
from a new senior credit facility provided by a syndicate of major international
banks. The acquisition has been accounted for as a purchase and the results of
Cynara have been included in the consolidated financial statements since the
date of acquisition. Goodwill at December 31, 1999 and December 31, 1998 was
$13,480 and $11,622, respectively. Accumulated amortization was $577 and $30,
for the respective periods.

     At December 31, 1999 and December 31, 1998, inventories valued using the
LIFO method and included above amounted to $14,639 and $16,060, respectively.
For the year ended December 31, 1999, liquidations of LIFO layers resulted in a
reduction of cost of sales of $21. There was no reduction in the LIFO layers for
the nine months ended December 31, 1998 or the year ended March 31, 1998.

(10) SHORT-TERM DEBT

     At December 31, 1999 and December 31, 1998, NATCO had a working capital
facility for export sales of $10.0 million and $5.0 million, respectively. The
loans bear interest at prime, which was 8.50% and 7.75% respectively as of
December 31, 1999 and December 31, 1998. Borrowings are based on the value of
inventory and accounts receivable. The bank facility is secured by specific
project inventory and receivables, a 90% guarantee from EXIM bank, and a second
lien on the assets pledged to the NATCO revolving credit bank loan. The working
capital facilities and loans are annual programs. The facility in place as of
December 31, 1999, matures on July 23, 2002. No borrowings were outstanding
under this facility as of December 31, 1999. The outstanding balance at December
31, 1998 was $1,585. The Company had letters of credit outstanding under this
facility totaling $7,360 and $523 at December 31, 1999 and December 31, 1998,
respectively.

     NATCO. On November 20, 1998, a revolving credit and term loan facility was
put into place with a syndicate of major international banks. The credit
facility provides for a $32,000 revolving credit line ($22,000 available in the
U.S., $10,000 available in Canada) to finance eligible accounts receivable and
inventories, and a $32,500 term loan. Indebtedness under the credit facility
bears interest at a floating rate based (at the Company's option) upon (i) the
Base Rate, or Canadian prime rate with respect to Base Rate Loans, plus the
Margin Percentage or (ii) the London Interbank Offered Rate for one, two, three
or six months, plus the Margin Percentage. The Margin Percentage for Base Rate
and Canadian prime rate loans varies from 1.00% to 0.00% depending on the
Company's debt to capitalization ratio; and the Margin Percentage for Eurodollar
loans varies from 2.50% to 1.00% depending on the Company's debt to
capitalization ratio. The term borrowings mature on November 30, 2003, and the
revolving borrowings mature on November 30, 2001. These agreements contain
affirmative covenants including financial requirements related to minimum net
worth, debt to capitalization ratio, and fixed charge coverage ratio, as well as
restrictions on NATCO making any distributions of any property or cash to the
Company in excess of an agreed sum without prior lender approval, and requires
commitment fees in accordance with standard banking practices. The loan is
collateralized by substantially all the assets of the Company and its
subsidiaries, as well as a guarantee by the Company. As of December 31, 1999,
the Company was in compliance with all restrictive covenants. NATCO had letters
of credit outstanding under the revolving credit facilities totaling $2,553 at
December 31, 1999. These letters of credit constitute contract performance and
warranty collateral and expire at various dates through September 2002.

     The industrial revenue bond was secured by plant, real property, and
equipment of NATCO and was also guaranteed by NATCO. Interest ranged from 7.9%
to 8.5%, payable semiannually. On August 4, 1999, the Company sold this facility
which had been leased under a long-term agreement for $950. The net book value
of the facility at the time of the sale was approximately $385. Proceeds from
the sale were used to retire the industrial development revenue bond related to
the facility which amounted to $715, with the remaining amount applied to the
Company's outstanding revolver balances.

     Dividend Restrictions. With respect to its new credit facilities, NATCO has
agreed that it will not make any distributions of any property or cash to the
Company or its stockholders' in excess of $1,500 for 1998, $2,000 for 1999, and
$2,200 for any year thereafter, plus 50% of excess cash flow beginning in 2001.

     The Company's previous Canadian loan facility contained various restrictive
covenants which included, but were not limited to, restrictions on the aggregate
of capital expenditures and/or dividends paid in any one fiscal year not to
exceed 50% of net cash flow, defined as the sum of after tax net profit plus
depreciation/amortization and deferred taxes less payments made on long term
debt. For the fiscal year ended March 31, 1998, NATCO Canada was restricted from
making any such payments in excess of $1,699.

     Parent Company. On December 11, 1991, the Company issued its promissory
notes to Capricorn to evidence borrowings of $5,000. The notes were subordinated
to all senior debt of the Company. Thereafter, interest payments were deferred
and added to the principal amount of the notes. During the period prior to June
1997, the maturity dates of these notes were extended to 2000 and $4,600 thereof
was assumed, with the consent of Capricorn, by PTH in connection with the
distribution by the Company of the capital stock of PTH to Capricorn. In
conjunction with the refinancing of its domestic debt facility, the remaining
notes plus accrued but unpaid interest held by Capricorn were exchanged for
$5,100 in principal amount of the Company's 13% Subordinated Promissory Note due
2000 (the "Cap I Note").

     In June 1997, the Company completed the refinancing of its domestic debt
facility, in part to finance the acquisition of TEST. At that time, Capricorn II
invested an aggregate of $13,000 in the Company and received in exchange
2,113,334 shares of common stock and $2,400 in principal amount of the Company's
13% Subordinated Promissory Note due 2000 (the "Cap II Note"), the terms of
which are, except for the principal amount, identical to the Cap I Note. The 13%
subordinated notes are convertible into 1,479,258 shares of Company common
stock. Effective April 1, 1998, the Cap I and Cap II Notes were converted into
common stock of the Company.

     At December 31, 1999 and December 31, 1998, the Company did not record a
valuation allowance related to its deferred tax assets because it is the opinion
of management that future operations will more likely than not generate
sufficient taxable income to realize the deferred tax assets. At December 31,
1999, the Company has net operating loss carry-forwards for federal income tax
purposes of $1,930 that are available to offset future federal income tax, if
any, through 2019.

     Income tax expense differs from the amount computed by applying the U.S.
federal income tax rate of 34% to income from continuing operations before
income taxes as a result of the following:

     A provision has not been made for U.S. income taxes that would be payable
if undistributed earnings of foreign subsidiaries were distributed to the
Company in the form of dividends, since it is management's intention to reinvest

1999 and December 31, 1998, such amounts were not significant.

(13) STOCKHOLDERS' EQUITY

     CEO Stock Options. In connection with the engagement of Nathaniel A.
Gregory as the chief executive officer of the Company, the Company granted to
him options to purchase NATCO common stock that were subsequently converted to
options to purchase common stock of the Company. At December 31, 1998 and March
31, 1998, these options related to an aggregate of 905,104 shares of Company
common stock. Outstanding options at December 31, 1999 totaled an aggregate of
880,104 shares.

     Stock Appreciation Rights. During 1994, NATCO adopted the National Tank
Company Stock Appreciation Rights Plan (the National Tank Plan). The National
Tank Plan provided for grants to officers and key employees of NATCO of rights
to the appreciation in value of a stated number of shares of NATCO common stock.
Value was to be determined by a committee of the NATCO board of directors. The
maximum number of rights issuable under the National Tank Plan was 500,000.
Rights vested over a three year period. At March 31, 1997, there were 390,005
rights outstanding, of which 290,080 were vested. Compensation expense has been
adjusted in connection with the plan for the nine months ended December 31, 1998
and the year ended March 31, 1998 to reflect expense of $23 and $86,
respectively. Rights under this plan were converted to stock options as
discussed below.

     Individual Stock Options. On July 1, 1997, the board of directors of the
Company approved the exchange of rights outstanding, discussed previously, under
the National Tank Plan for individual options to purchase common stock of the
Company. The exercise price of these options was equal to fair market value of
the common stock. Accordingly, no compensation expense was recorded. These
individual stock options granted on July 1, 1997 vested ratably over a period of
three years in accordance with terms of the original stock appreciation rights.
New options issued on July 1, 1997 vested ratably over a four year period. The
maximum term of these options was 7.5 years. The Company reserved an aggregate
of 390,005 shares of common stock for issuance upon exercise of these individual
stock options.

     Stock Options Plans. In January 1998 and February 1998, the Company adopted
the Directors Compensation Plan and the Employee Stock Incentive Plan. These
plans authorize the issuance of options to purchase up to an aggregate of
760,000 shares of Company common stock. The options vest over periods of up to
four years. The maximum term under these options is ten years. At December 31,
1999, December 31, 1998 and March 31, 1998, options relating to an aggregate of
455,085, 464,672 and 260,006 shares were outstanding under these plans.

     The following table summarizes the transactions of the company's stock
option plans for the year ended December 31, 1999, the nine months ended
December 31, 1998 and the year ended March 31, 1998:

     Pro forma information regarding net income and earnings per share is
required by SFAS 123, and has been determined as if the Company had accounted
for its employee stock options under the minimum value method of this statement
under the assumptions of a risk free rate of 5.5% and an expected life of
options of 10 years for options issued during the year ended December 31, 1999
and the nine months ended December 31, 1998. For options issued prior to March
31, 1998, the risk free rate of return used was 7% and the expected life used
was 7.5 years.

     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma net earnings and earnings per share for the year ended December 31,
1999, the nine months ending December 31, 1998, and the year ended March 31,
1998 were as follows:

</TABLE>

     Because the statement provides for pro forma amounts for options granted
beginning in 1995, the pro forma expense will likely increase in future years as
the new option grants become subject to the pricing model.

Preferred Stock Purchase Rights

     In May 1998, the board of directors of the Company declared a dividend of
one preferred share purchase right (right) for each outstanding share of common
stock and for each share of common stock thereafter issued prior to the time the
rights become exercisable. When the rights become exercisable, each right will
entitle the holder to purchase one one-hundredth of one share of Series A Junior
Participating Preferred Stock at a price of $72.50 in cash. Until the rights
become exercisable, they will be evidenced by the certificates or ownership of
our common stock and they will not be transferable apart from the common stock.

     The rights will become exercisable following the tenth day after a person
or group announces acquisition of 15% or more of the Company's common stock or
announces commencement of a tender offer the consummation of which would result
in ownership by the person or group of 15% or more of the common stock. If a
person or group were to acquire 15% or more of the Company's common stock, each
right would become a right to buy that number of shares of common stock that
would have a market value of two times

                                       39
<PAGE>   40

the exercise price of the right. Rights beneficially owned by the acquiring
person or group would, however, become void.

     At any time prior to the time the rights become exercisable, the board of
directors may redeem the rights at a price of $0.01 per right. At any time after
the acquisition by a person or group of 15% or more but less than 50% of the
common stock, the board may redeem all or part of the rights by issuing common
stock in exchange for them at the rate of one share of common stock for each two
shares of common stock for which each right is then exercisable. The rights will
expire on May 15, 2008 unless previously extended or redeemed.

(14) PENSION AND OTHER POSTRETIREMENT BENEFITS

     The Company has adopted SFAS 132, which revised disclosures about pension
and other postretirement benefit plans. Disclosures regarding pension benefits
represent the plan for certain union employees of a foreign subsidiary.
Disclosures regarding postretirement benefits represent health care and life
insurance benefits for employees who were retired at the time the Company was
acquired from C-E.

     In December 1999, the Company entered into an agreement with Tyler, and
Capricorn I, in which the Company assumed responsibility for the retired
employee health and life insurance obligations of Tyler. The liability accrued
with respect to these obligations, as determined by an independent actuarial
firm, is $1,063. In consideration of this agreement, Tyler paid the Company $400
in cash and assigned a portion of the federal income tax refund due to Tyler in
the amount of $600. Capricorn I guaranteed payment of the latter amount. See
Note 23, Subsequent Events for further discussion.

     The following table sets forth the plan's benefit obligation, fair value of
plan assets, and funded status at December 31, 1999 and December 31, 1998.

     Deferred Compensation Plan. TEST adopted a deferred compensation plan (the
TEST Plan) effective July 1, 1995 to provide incentives and rewards to certain
individuals. Awards are payable in five equal annual installments plus any
earnings, which have been allocated to a participant's account. The Company has
elected not to make any additional awards for the plan year beginning January 1,
1998. As of December 31, 1999 and December 31, 1998, the total amounts owed
under the TEST Plan were $303 and $578, respectively. The balance presently
accrues interest at the prime rate plus 1%.

     Defined Contribution Plans. The Company and its subsidiaries each have
defined contribution pension plans covering substantially all nonunion hourly
and salaried employees who have completed three months of service. Employee
contributions of up to 3% of each covered employee's compensation are matched
100% by the Company, with an additional 2% of covered employee's compensation
matched at 50%. In addition, the Company may make discretionary contributions as
profit sharing contributions. Company contributions to the plan totaled $1,638,
$1,912, and $912 for the year ended December 31, 1999, the nine months ended
December 31, 1998 and the year ended March 31, 1998, respectively.

(15) OPERATING LEASES

     The Company and its subsidiaries lease various facilities and equipment
under non-cancelable operating lease agreements. These leases expire on various
dates through 2003. Future minimum lease payments required under operating
leases that have remaining non-cancelable lease terms in excess of one year at
December 31, 1999, are as follows: 2000 -- $2,640, 2001 -- $1,514, 2002 -- $671,
2003 -- $225, and 2004 -- $85. Total expense for operating leases for the year
ended December 31, 1999, the nine months ended December 31, 1998, and the year
ended March 31, 1998 was $3,169, $2,298, and $2,563, respectively.

     For a discussion of lease and rental income, see Property, Plant and
Equipment, net (Note 7).

(16) RELATED PARTIES

     The Company agreed in 1989 to pay $350 per year plus specified
out-of-pocket expenses to Capricorn Management to reimburse Capricorn Management
for costs and expenses incurred by it and its employees in performing specified
management and other responsibilities. These services included, during the
periods of their common ownership, services to PTH, whose capital stock the
Company distributed to Capricorn I on June 30, 1997, and to another affiliate
which has been sold. Effective July 1, 1997, the parties amended the contract to
limit the services provided by Capricorn Management to advisory information and
research services and administrative services and to reduce the cost
reimbursement to $75 per year. The services provided include office space and
parking in Connecticut for the Company's Chief Executive Officer and

                                       41
<PAGE>   42

reception, telephone and computer services and other normal office support
relating to that space. Fees paid to Capricorn Management totaled $75, $56 and
$163, for the year ended December 31, 1999, the nine months ended December 31,
1998 and the year ended March 31, 1998, respectively.

     Employees of Capricorn Management have participated in various NATCO
employee benefit plans and the Company has from time to time received billings
from vendors for services provided to Capricorn Management personnel acting for
the benefit of the Company. Capricorn Management reimburses the Company for the
foregoing expenses. At December 31, 1999 and December 31, 1998, Capricorn
Management owed the Company $5 and $16, respectively, for these expenses.

     For the year ended December 31, 1999, the nine months ended December 31,
1998 and the year ended March 31, 1998, PTH paid $84, $49, and $95,
respectively, to the Company for tax consulting and analysis services.

     Effective December 31, 1994, Capricorn entered into an option agreement
with a former officer and 2.5% stockholder of the Company (see above). The
option, which enabled the stockholder to exchange common stock for a specified
interest in a note from the Company, was exercised on May 10, 1995 for an 18%
subordinated note for $1,330 (see note 11). Also, during fiscal year 1997,
Capricorn purchased $1,079 of the note from the note holder. During the fiscal
year ended March 31, 1998, Capricorn purchased the remaining portion of the
note.

     During 1997, the Company loaned the amount of $1,525 (at a rate of 10% per
annum) to a director of the Company who is also an affiliate of Capricorn. In
March 1998, the related promissory note was amended to change the interest rate
to 11% per annum. The principal is due on the date on which Capricorn has
distributed its holding of Company common stock to its partners. During 1998,
the Company acquired an option at a cost of $200 to purchase 173,050 shares of
Company common stock from the director at a price of $8.81 per share. At the
Company's option, the note may be repaid with shares of the common stock of the
Company. The cost to acquire the option has been recorded as treasury stock in
the accompanying consolidated balance sheet. Refer to discussion at Subsequent
Events (Note 23).

     An executive officer of the Company has an employment agreement pursuant to
which he was entitled to a bonus upon the occurrence of any sale or public
offering of the Company. Such bonus was to equal one and one-half percent (1.5%)
of the value of all securities owned by stockholders of the Company prior to the
sale or offering, including common stock valued at the price per share received
in either the sale or public offering, and any debt held by such stockholders.
In July 1999, the Company amended the agreement to eliminate the bonus. Instead
the Company agreed to lend the officer $1,205 to purchase 136,832 shares of
common stock. The loan accrues interest at 6% annually. The officer will receive
a bonus equal to the outstanding principal and interest of the note upon the
sale or public offering of the Company. Refer to discussion at Subsequent Events
(Note 23).

     During December 1999, the Company assumed the postretirement pension
liability of a former affiliate, Tyler. Refer to discussion at Pensions and
Other Postretirement Benefits (Note 14).

(17) DISCONTINUED OPERATIONS -- PTH

     PTH manufactures vibrating screens, rock crushing equipment, conveyor
components and screening media with operations in the United States, Canada, and
Scotland. On June 30, 1997 the Company completed the tax-free spin-off of PTH by
distributing the 14,250 shares of PTH stock that it owned to Capricorn I as the
holder of its common stock. Capricorn I was the sole stockholder of the Company
at the time of distribution, and accordingly this transaction was recorded on a
historical cost basis. The spin-off distribution reduced stockholders' equity by
$4,558 that represents the net assets of PTH at the date of spin-off including
the assumption of $4,576 of debt owed by the Company to Capricorn and the
forgiveness of $2,347 of intercompany balances.

     The historical results for discontinued operations include an allocation of
the Company's nonspecific interest expense based on the ratio of net assets for
PTH divided by the sum of net assets of the Company, plus all the Company's
debt. Debt and interest expense directly incurred by NATCO was excluded from the
ratio.
                                       42
<PAGE>   43

Interest expense for the Company attributable to the operations of PTH and
included in the profit and loss from discontinued operations for the year ending
March 31, 1998, up to and including the disposal date of June 30, 1997, was
$285.

     At the time of the spin-off, the Company and PTH entered into a tax sharing
agreement with provisions for determining responsibility for tax liabilities of
PTH for the years that PTH was included in the Company's consolidated tax
returns. Income taxes have been allocated to PTH based on its pretax income and
calculated on a separate company basis pursuant to the requirements of SFAS No.
109, "Accounting for Income Taxes". Income tax allocated to PTH for the year
ended March 31, 1998 was $395.

     Summarized financial data for the discontinued operations are as follows:

(18) COMMITMENTS AND CONTINGENCIES

     In June 1997, the Company, in connection with a financing effected to
provide funds for the acquisition of TEST and other corporate purposes,
distributed all of the outstanding stock of PTH then owned by the Company to its
then sole stockholder, Capricorn. In connection with the distribution, the
Company received an opinion of counsel to the effect that the distribution would
be tax-free to both the Company and Capricorn. Tax-free treatment of the
distribution depends, in part, upon the underlying facts and circumstances at
the time of the distribution. There can be no assurance that the Internal
Revenue Service will agree with the interpretation of the Company and its
counsel of such facts and circumstances. If the Internal Revenue Service were to
challenge the tax-free treatment of the distribution and such challenge were
ultimately to prevail, the Company would be treated as recognizing gain with
respect to the distribution in an amount equal to the excess of the fair market
value of the PTH stock at the time of the distribution over its tax basis to the
Company. Such treatment could have a material adverse effect on the Company's
results of operations and financial condition.

(19) LITIGATION

     The Company is a party to various routine legal proceedings. These
primarily involve commercial claims, products liability claims, asbestos related
personal injury claims and workers' compensation claims. We cannot predict the
outcome of these lawsuits, legal proceedings and claims with certainty.
Nevertheless, we believe that the outcome of all of these proceedings, even if
determined adversely, would not have a material adverse effect on our business
or financial condition.

(20) INDUSTRY SEGMENTS AND GEOGRAPHIC INFORMATION

     The Company has adopted the provisions of SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information." The Company's eight business
units have separate management teams and infrastructures that offer different
products and services. The business units have been aggregated into

                                       43
<PAGE>   44

four reportable segments (described below) since the long-term financial
performance of these reportable segments is affected by similar economic
conditions.

     Engineered Systems: This segment consists of five business units; U.S.
Engineered Systems, Cynara, NATCO Japan, NATCO Venezuela, and NATCO London, that
provide design, engineering, manufacturing and start-up services for engineered
process systems. The principal markets for this segment include all major oil
and gas producing regions of the world including North America, Latin America,
Europe, Africa and the Far East. Customers include major multi-national,
independent and national or state-owned companies.

     Traditional Production Equipment and Services: U.S. Sales & Service is the
sole business unit reported in this segment. This unit designs, engineers,
manufactures, and provides start-up services for production equipment, which is
generally less complex than those units provided by Engineered Systems. This
segment also provides replacement parts, field and shop servicing of equipment,
and used equipment refurbishing. The principal market for this segment is the
U.S. onshore and offshore market, but also serves the international market.
Customers include major multi-national, independent and national or state-owned
companies.

     Instrumentation and Electrical Systems: TEST is the sole business unit
reported in this segment. This unit designs, manufactures, installs and services
instrumentation and electrical control systems. The principal markets for this
segment include all major oil and gas producing regions of the world including
North America, Latin America, Europe, Kazakhstan, Africa and the Far East.
Customers include major multi-national, independent and national or state-owned
companies.

     NATCO Canada: This segment consists of our subsidiary in Canada. NATCO
Canada provides design, engineering, manufacturing and start-up services for
engineered process systems. It also provides replacement parts, field and shop
servicing of equipment, and used equipment refurbishing. NATCO Canada has also
done selective manufacturing for the Engineered Systems segment in the past. The
principal markets for this segment are the oil and gas producing regions of
Canada. Customers include major multi-national and independent companies.

     The accounting policies of the reportable segments are the same as those
described in Note 2. The Company evaluates the performance of its operating
segments based on income before net interest expense, income taxes, depreciation
and amortization expense, gains and losses from revaluations of postretirement
benefit liability and interest cost on postretirement benefit liability,
accounting changes, and nonrecurring items. Summarized financial information
concerning the Company's reportable segments is shown in the following table.

(22) OFFICE CLOSURE

     Prior to 1997, the Company began winding down the operations of NATCO U.K.
Ltd. These activities include transferring the net assets and employees at the
Company's parts and service business to a new U.S. subsidiary, NATCO London,
Inc., and resolving pending severance, office closure and leasehold issues.
Included in the March 31, 1998 statement of operations is a charge of $282
recognized as the estimated cost to exit these activities, which principally
consists of lease termination costs, and professional fees associated with
winding down the operation.

     During the year ended December 31, 1999, the Company completed the closure
and reached favorable settlements related to various amounts owed to and by
customers and vendors related to a number of contracts entered into between 1993
and 1995. An accrual for the costs associated with these various claims had been
made during fiscal years 1995 through 1998 based on the best available
information at that time. As a result of favorable settlements, the Company
revised its previous estimates and reversed $314 of these accruals.

(23) SUBSEQUENT EVENTS

     On January 27, 2000, the Company completed an initial public offering of
7,500,000 shares of Class A common stock at a price of $10.00 per share
(4,053,807 shares issued by the Company and 3,446,193 shares issued by selling
stockholders). The proceeds to the Company, less underwriting fees, were
$37,700. These funds were used to retire debt of $22,857 under the revolving
credit facility and to complete the acquisition of Porta-Test International,
Inc. On February 3, 2000, the underwriter exercised its over-allotment option
which resulted in the issuance of 1,125,000 additional shares of Class A common
stock and proceeds of $10,463, net of fees. These proceeds were used for a
pending acquisition of Modular Production Equipment, Inc. and other working
capital needs.

     In September and October 1999, the Company executed non-binding letters of
intent to acquire Porta-Test International Inc., Engineering Specialties, Inc.
and Modular Production Equipment, Inc. The Company closed the Porta-Test
International, Inc. transaction on January 24, 2000 for approximately $5,400 in
cash, net of cash acquired, and the issuance of a one-year promissory note for
approximately $700. On February 8, 2000, the Company closed the Modular
Production Equipment, Inc. transaction for approximately $2,500 in cash, net of
cash acquired, and the issuance of a one-year promissory note for approximately
$300. Purchase price allocations have not yet been finalized for these
acquisitions.

     As the Company's initial public offering became effective during January
2000, a bonus arrangement with an officer of the Company was executed in partial
settlement of a $1,242 note receivable and accrued interest recorded as of
December 31, 1999. Under this arrangement, in February 2000, the Company
recorded compensation expense of $1,248. The officer used the proceeds of this
bonus payment, net of tax, to repay $665 of the debt outstanding. As of February
29, 2000, the balance of the receivable and accrued interest from this officer
was $583. See Note 16, Related Parties.

     A note arrangement with a director, recorded as a $1,890 current asset at
December 31, 1999, was partially settled during February 2000, when the Company
exercised an option to purchase 173,050 shares of its common stock from this
director at a cost of $1,525. The remaining balance of the note at February 29,
2000, was $365. See Note 16, Related Parties.

     In February 2000, the Company received $613 from Tyler as settlement of an
agreement entered into between Tyler, Capricorn I and the Company, whereby the
Company assumed responsibility for the retired employee health and life
insurance obligations of Tyler. See Note 14, Pension and Other Postretirement
