                                     Part I

Item 1. BUSINESS

General:

     The Company designs, manufactures, sells and services thermal processing
equipment and related process controls for use in the electronics, power
generation, automotive and other industries. The Company is the major supplier
of solder reflow systems used in printed circuit board surface mount
applications. The Company is a principal worldwide supplier of systems used in:
low temperature curing/encapsulation; hybrid integrated circuit manufacturing;
integrated circuit packaging and sealing; and processing multi-chip modules. The
Company is a leading supplier of systems for sintering nuclear fuel for
commercial power generation. In addition, its products are used in other
specialty applications such as brazing and the sintering of ceramics and
powdered metals, and the deposition of precise thin film coatings.

The Company has focused on three key strategic areas:

     TECHNOLOGICAL LEADERSHIP - As process parameters change, with higher speed
     and higher density components and printed circuit boards, the Company has
     responded by developing and introducing systems which advance the state of
     the art in processing for many applications and industries.

     PRODUCT DIVERSIFICATION - The Company utilizes it's core technologies to
     satisfy our customers' changing needs by offering a variety of systems
     capable of processing material from 100(Degree)C to 2000(Degree)C. These
     systems are marketed at a wide range of price levels for our various
     applications which include; surface mount device solder reflow, epoxy
     curing, integrated circuit packaging and thick film, metals, ceramic and
     nuclear fuel sintering, and other applications.

     CUSTOMER SUPPORT - As thermal processing systems become more complex and
     require greater support, many customers, especially those in high-volume
     production, prefer dealing with a limited number of large capital equipment
     suppliers. The Company's reputation for system performance and
     technological innovation, together with its established worldwide service
     organization, is an important strength in selling to manufacturers for
     high-volume production applications.

Products:

     The thermal processing applications performed by the Company's products are
     used in the manufacture of:

        Surface Mount Technology (SMT) Solder Reflow
        Low Temperature Epoxy Curing/Encapsulation
        PC Board Multi Chip Modules (MCM-L)
        Conductive Polymer Thick Film Curing
        Hybrid Microelectronics
        Integrated  Circuit  Packaging  (Ball Frid Array - BGA,  Micro BGA,  and
          Chips Seale  Packaging - CSP)
        Ceramic  Multilayer  Package & Multi Chip Module Firing  (MCM-C)
        Nuclear Fuel  Sintering
        Photovoltaics  Chemical Vapor Deposition (CVD) & Optoelectronics Thin
          Film Deposition
        Refractory & Powdered  Metal  Sintering
        Technical  Ceramic  Sintering
        Brazing of Electronic, Electrical, Automotive and Medical Components
        CRT Coating

      These products perform thermal processes either in a continuous or in a
        batch mode:

        Solder Reflow Systems
        Conveyor  Curing Systems
        Continuous Belt Conveyor Processing Systems
        High Temperature (up to 2000(Degree)C) Systems  (continuous  and batch)
        Atmospheric  Pressure  Chemical  Vapor Deposition (APCVD) Systems

     Each system has precise microprocessor controlled functions, such as
process gas measurement, temperature control and profiling, time sequencing, and
Computer Intergrated Manufacturing (CIM) - SECS/GEM Machine Interface Software.

                                       1
<PAGE>   4

     The technological change in processing is driven by the trends toward
miniaturization (hand held products), higher circuit densities, and the need for
advanced controls with cleaner process environments. The trend toward automation
to support highly reproducible processes is a requirement for most applications.
Customer needs for a high level of service and spare parts support leads to a
preference for the large capital equipment supplier with a broad technological
base and an established reputation for quality. Remote diagnosis of field
equipment from BTU's factory (via modem) increases equipment availability
(uptime).

     Solder Reflow Systems

     Convection solder reflow systems, with or without controlled atmosphere,
have become the preferred method of attaching surface mount devices to high
density printed circuit boards. Solder, in the form of a paste, is applied to
the printed circuit board and surface mount devices are placed on the solder
paste. The assembly is then heated in a continuous multi-zoned recirculated
convection process to above the melting temperature of the solder, after which
the product is rapidly cooled by convection to solidify the solder. Uniform
heating and cooling of the product is required to prevent stresses and component
overheating.

     Surface mount technology is contributing to the miniaturization of
high-density printed circuit boards and allows board designs with components on
both top and bottom. Surface mount technology is now the standard for high
density printed circuit board assembly. Prices for the Company's solder reflow
systems range from $35,000 to $200,000.

     Conveyor Epoxy/Polymer Thick Film (PTF) Curing Systems

     BTU's conveyor curing systems have process applications in several stages
of Printed Circuit Board (PCB) manufacturing to cure/encapsulate conductive or
dielectric epoxy at temperatures up to 225(Degree)C. The system allows fast,
stable curing/encapsulation at a controlled temperature. Epoxy material
developments have dramatically reduced cure times that should expand the market
for these curing systems for PC board and electronic packaging. Prices for the
Company's curing/encapsulation systems range from $ 25,000 to $150,000.

     Continuous Belt Processing Systems

     BTU's continuous belt processing systems are used in a variety of
applications (such as integrated circuit packaging, hybrid circuit
manufacturing, brazing of automotive components, etc.). These systems operate
between 300(Degree)C and 1200(Degree)C and may measure up to 60 feet long. They
can be equipped with one or more gas barriers and atmospheric zones and may vary
in length of heating zones from four to forty-eight feet. Depending upon load
capacity requirements, conveyor belt widths vary from four to forty-eight
inches. Prices for these systems range from $30,000 to $800,000.

     High Temperature Systems

     BTU offers walking beam, special batch systems and pusher systems for high
temperature processing with heavy loads. The Company's walking beam system
employs a proprietary conveyance mechanism that can process loads of up to 800
pounds per square foot at temperatures up to 2000(Degree)C.

     A major application for this high-temperature product is sintering
multilayer integrated circuit packages. In addition, these systems are used in
sintering technical ceramics, nuclear fuels and refractory and powdered metals.
These systems are usually customized and vary in price from $250,000 to
$2,500,000.

     Atmospheric Pressure Chemical Vapor Deposition Systems

     Atmospheric pressure chemical vapor deposition ("APCVD") is a thin film
deposition process in which the vapors of two or more chemicals are mixed in a
controlled environment at elevated temperatures at atmospheric pressure. A
chemical reaction occurs at these elevated temperatures causing a thin film to
be deposited on the desired substrate. The process is typically carried out in a
continuous belt processing system at throughput rates of one to four square feet
per minute.

     The Company's APCVD systems, which sell for between $250,000 and
$1,000,000, are used in the manufacture of silicon devices, photovoltaics and
optoelectronic devices.

                                       2

Marketing, Sales and Customers:

     The Company's worldwide customer base consists primarily of independent
manufacturers of electronic devices, computers, telecommunications, printed
circuit board assembly houses, and other companies in the electronics industry.
Other customers include nuclear fuel manufacturers and technical ceramics
manufacturers and producers using specialty brazing applications. Repeat sales
to existing customers represent a significant portion of the Company's revenue.

     The Company markets its products through the combined efforts of a direct
sales force and independent sales/service representatives. Direct sales/service
offices are maintained in the United States, England, Scotland, Germany,
Singapore and China. Independent sales/service representatives are located in
all major industrialized countries worldwide.

     The Company operates on a world wide bases in support of its multinational
customer base. The following table shows the percentages of the Company's
revenues in the United States, Europe and the Far East, for the last three
years:

                                  1996              1995              1994
                                  ----              ----              ----
 United States                     47%               52%               48%
 Europe                            25                19                28
 Far East                          23                24                18
 Other                              5                 5                 6

     For further information on export sales and foreign operations, see Note 4
of the Company's Consolidated Financial Statements.

     Reliability, performance, uptime and meantime-to-repair (MTR) and cost of
ownership, together with technological leadership, are important factors by
which customers evaluate potential suppliers of sophisticated processing
systems. The Company supports its customers with field service, training
programs, parts sales and operating manuals. Technical support is also available
through either direct telephone links or on-site Company personnel to provide
assistance in process support and the service and maintenance of equipment.

     One customer individually represented approximately 21% of revenue in 1994.
No individual customer accounted for greater than 10% of revenues in 1996 or
1995.

     The Company does not consider its business to be seasonal in nature, but it
is cyclical dependent on the capital equipment procurement pattern of its
customers.

Backlog:

     Backlog was $ 8.1 million at December 31, 1996 versus $8.7 million at
December 31, 1995. The primary reason for the decrease is a slow down in the
electronics industry during 1996. Most of the Company's backlog is expected to
be shipped within 3 to 6 months. The Company includes in backlog only those
orders for which a purchase order has been assigned by the customer and a
delivery schedule has been specified. Because of possible changes in delivery
schedules and order cancellations, the Company's backlog at any particular date
is not necessarily representative of sales for any succeeding period.

Manufacturing and Raw Materials:

     The Company manufactures a portion of its equipment to custom
specifications. On the custom equipment orders raw material inventory is
typically purchased only after an order is received. In the case of standard
equipment, certain raw materials may be purchased based upon forecast.
Manufacturing costs are financed in part through progress payments, especially
in the case of deliveries with long lead times.

     The Company has an integrated manufacturing operation in the United States,
and purchases certain standard components and designs and manufactures others.
Although the Company relies upon single sources for certain parts, it believes
that alternative sources of supply are available in each case. The Company has
not experienced any disruption in its business due to an inadequate supply of
materials.

                                       3
<PAGE>   6

Research, Development and Engineering:

     The Company's research, development and engineering programs are devoted to
the enhancement of existing systems and the development of new systems for new
applications. As the complexity of producing miniaturized circuitry increases,
the electronics and other industries are working more closely with larger,
capital equipment suppliers to determine and develop future product and process
needs. The Company's current internally financed efforts include development of
enhanced convection heat transfer systems for solder reflow, new deposition
processes in APCVD, advanced controls and related software systems.

Competition:

     There are numerous suppliers of thermal processing systems for the
electronic and other industrial thermal processing applications. Although buying
decisions have traditionally focused on price, the Company believes that
technological leadership, process capability, throughput, environmental
safeguards, uptime, meantime-to-repair, cost of ownership, and after sale
support have become increasingly important factors. It is on the basis of these
criteria, rather than primarily on price, that the Company competes in its
markets.

     The Company's principal competitors for integrated circuit packaging and
hybrid circuit manufacturing systems vary by product application. In conveyor
belt systems, Lindberg (a division of General Signal) and SierraTherm are the
Company's principal competitors. In high temperature systems, the principal
competitors are Lindberg, Cremar and De Gussa. In solder reflow systems, the
principal competitors are Vitronics, Electrovert (a division of Cookson Group
PLC) and Heller.

     The electronics industry is characterized by rapid technological change.
The Company must continue its development efforts to compete effectively.
Introduction of improved systems or techniques by others without a similar
advance by the Company could adversely affect the Company's prospects.

Patents and Trademarks:

     The Company holds many US and foreign patents, and it will continue to seek
patents on inventions that result from its research and development activities.
Although it believes its patents are of value, the Company depends primarily on
its technological creativity and know-how, rather than on its patents, to
maintain its competitive position. The Company also owns certain trademarks and
proprietary information that it considers important to its business and that it
seeks to protect through appropriate means.

Environmental:

     Compliance with laws and regulations regarding the discharge of materials
into the environment, or otherwise relating to the protection of the
environment, has not had any material effects on the capital expenditures,
earnings or competitive position of the Company. The Company does not anticipate
any material capital expenditures for environmental control facilities in 1997.

Employees:

     As of December 31, 1996, the Company had a total of 323 employees of which
302 were domestic and 21 were foreign based. None of the Company's employees are
represented by a union or other collective bargaining agent, and the Company
considers its relations with its employees to be good.

Item 2.  PROPERTIES

     The Company maintains its headquarters in North Billerica, Massachusetts,
where it owns a 150,000 square foot manufacturing facility and leases an
additional 17,000 square feet of manufacturing space. The Company operates its
manufacturing facility on a full first shift and partial second shift basis. In
England, for its European sales and service operations, the Company operates out
of a leased facility which expires in 2010. The Company believes that its plants
and capital equipment operated at approximately 65% of productive capacity
during the fourth quarter of 1996 and that such plants and capital equipment
provide sufficient manufacturing capacity through 1997.

Dear Fellow Shareholders:

After improving our performance each year for the past five years and achieving
record sales and earnings in 1995, 1996 was a reminder that the nature of
business is no different than the nature of life. Our best intentions and
pre-set plans need to be modified to better respond to the challenges of the
marketplace. The historic economic reality of successful capital equipment
suppliers to the electronics industry has been one of adapting quickly and
effectively to the fluctuations in business cycles, while remaining steadfast in
pursuing long-term objectives. Such was the case for BTU during 1996.

In 1996, the electronic industry purchases of process equipment were well below
the record 1995 levels. This held true for both BTU's low temperature solder
reflow equipment used in the manufacture of printed circuit boards as well as
our high temperature process equipment used in a variety of other applications.
The decline was most significant in orders for multiple unit high end solder
reflow equipment used by the major multinational electronic companies. Partially
offsetting this decline was an increase in our worldwide customer base for low
to mid range solder reflow systems for which 1996 sales grew over 1995 levels.

This slowdown meant that during the year, we had to adjust and reset our goals
in line with the changing market place. Apart from the decline in sales, we also
saw a shift in the product mix in our solder reflow lines, which comprise about
60% of our total volume, towards medium and low end systems where margins were
under strong competitive pressures.

BTU's employees want to achieve results we can all be proud of, foremost as
measured by our world wide customer base. Our goal is to be a company which is
recognized as the leader by our customers, employees and the investment
community. To this end, we need to continue making changes to improve on many
fronts. I have listed some of the accomplishments as well as the disappointments
during 1996 and the actions we are taking to build a successful future.

1996 Accomplishments

- -     Notwithstanding the tough market environment, BTU increasingly focused on
      improving customer satisfaction levels for all its products and services.
      To achieve this, we started a restructuring within our organization aimed
      at aligning our organizational responses to the customer needs. We were
      also modifying our philosophy in manufacturing towards improved
      outsourcing capabilities. This restructuring will continue into 1997.

- -     In order to increase efficiencies and better align our capacity with the
      level of business, we started to streamline our organization during the
      year and reduced headcount by approximately 20%.

- -     The company undertook a major effort to reduce the cost of our medium and
      low end solder reflow lines. The results are expected to improve margins
      for these lines over time.

- -     R&D spending increased as a percentage of sales from 7% to 8%. This 
      allowed us to introduce several new products to existing markets and start
      additional products for new markets, which the company expects to
      penetrate in the next one to two years.

         The highlights of our R&D effort were:

      -     In our challenge to bring the best process equipment to our SMT
            customers we introduced a new high end line of reflow systems, The
            Paragon series, during 1996. This line will compliment and,
            partially take the place of our highly successful TRS systems, which
            are used by many multinational customers as the equipment of choice
            for high volume surface mount printed circuit board production.

      -     In the high temperature equipment sector, we introduced several new
            products for integrated circuits packaging applications: a new wafer
            bumping system which under hydrogen atmosphere reflows the solder
            directly on silicon wafers; and a new system for chip interconnects.
            We also introduced a new nuclear fuel sintering furnace for medium
            sized production, which compliments our large volume walking beam
            system for similar processes.

      -     With an eye on major emerging markets, we are in prototype
            development of several systems: One system is for processing large
            size flat panel displays for which BTU has signed a development
            agreement with a major multinational company. Another is for CRT
            displays, thin film deposition, for which we expect to have our
            first order in 1997. Although it is too early to predict successful
            market entries, we believe that BTU has the required core
            competencies to bring significant contributions to the above process
            applications.

- -     In June of 1996 we gainfully sold our remaining 19.4% interest in the
      Bruce Technologies, Inc. joint venture, which concluded BTU's exit as a
      participant in the front-end semiconductor equipment business. This helped
      to further strengthen our financial position with a $10.2 million cash 
      balance at the end of 1996.

- -     Shareholder equity increased from $18.7 million in 1995 to $22.2 million 
      in 1996 and increased almost two fold during the past 2 years.

- -     Net cash, i.e., cash minus debt (mortgage) increased by $4.5 million 
      during 1996.

- -     We were able to strengthen our organization in Europe and the Far East in
      support of our customer base in these parts of the world in recognition
      that more than 50% of our sales are outside the United States of America.

1996 Disappointments and Actions

- -     During 1996, we did not meet most of our financial targets, which was a
      major disappointment as expectations had led many to believe that the last
      half of 1996 would show an improvement in business climate. Consequently,
      we undertook several cost cutting measures, salaries for key executives
      were frozen and no bonuses were earned for 1996.

- -     We had higher than anticipated warranty costs due to inadequacies in
      release procedures and in testing of new products. This area is a major
      focus for improvement in 1997.

- -     Our revenues per employee dropped by 12% as we did not adjust, partly by
      default and partly by design, to the realities of the market place.

- -     Realizing that part of our improvement has to come from our leadership, we
      started a search to compliment our management team with a key individual
      to increase the speed of improvements and advancements necessary to
      capture the opportunities ahead of us.

- -     We have many excellent employees and strong contributors. In order to 
      fully develop their potential, we need to improve our ability to
      analyze and recognize the talent we have and do a better job at training,
      both in basic job skills as well as in advanced managerial and team
      building programs.

Although all of us at BTU had a tough year, many of us learned and vowed to
change, starting with the realization that we need to work on more effective
communications, measure our process results and identify ways to improve
performance levels throughout the organization.

1997 Onwards

During 1997, we will continue to implement our reorganization and focus on
streamlining the support of our world wide customer needs. We will be
exploring several opportunities in electronic and non electronic process
applications for which BTU has unique core technologies and where market
opportunities warrant the investment needed to succeed. In our quest to
continuously improve the quality of our processes and products, we have, among
other targets, the goal to be fully in compliance with the ISO 9001 standards by
October of 1997.

This year, we have included in our report an overview of our
key end user markets and the customer applications with process parameters for
our readers information. (See pages 4 and 5.) Early indications at the time of
this report are that major customers are starting to increase their capital
spending for 1997. If this trend continues, BTU expects to increase its level of
business after a slow start in early 1997.

Part of the future challenge is that all of the next millennium's customer's
needs require technologies that are cleaner, faster, smaller, more durable and
more precise. The other part of the future challenge is that all of these
improvements must come at a lower cost of ownership. The solutions to many of
these challenges are found in BTU's core competencies coupled with the
commitment to meet and exceed the thermal processing needs of our customers
around the world.

The actions outlined and many others which our employees are working on
including partnership programs with customers and suppliers are the steps to
build a strong company. This will be the foundation to meet our commitments     
to our customers, to increase shareholder values, and to create exciting and
challenging opportunities for our employees.

This page contains a graphic display of the Company's (BTU) customer
applications in a range of degrees centigrade and in specific atmospheres. At
the top of the page is the heading CUSTOMER APPLICATIONS. On the right side of
the page are degree centigrade markings from 0 at the bottom of the page, up to
2000 near the top of the page in 100 degree increments. To the right of these
numbers, starting at the number 2000 reads DEGREE CENTIGRADE, which is a label
for the numbers on the right side of the page. In the lower right portion of the
page is a legend box, indicating ATMOSPHERES of AIR , NITROGEN and HYDROGEN each
atmosphere name is within a rectangular shape with a different pattern
distinguishing each atmosphere. On the rest of the page are 9 rectangles
associated with the degrees in centigrade on the right margin. Each of these 9
rectangles are named at the bottom of the rectangle with an application. Each of
the rectangles vary in width and height, in that they are split in columns of
different patterns. There are three patterns used to indicate atmosphere(s)
which the application(s) can operate in. The information is presented as
follows:

1996 COMPARED TO 1995

During 1996 net sales decreased by $12.5 million to $45.8 million, representing
a decrease of 21.4% versus 1995. The major decrease in sales occurred in the
high-end surface mount technology products. These products are primarily used by
our large multinational customers. Most of these customers have significantly
decreased their capital expenditures in line with the slowdown in the
electronics industry during 1996. Sales of the company's mid-range surface mount
technology products continued to grow in part due to the increase in new
customers.

There were no material variations in the geographic dispersion of sales for 1996
as compared to 1995. The effect of price changes for specific products has not
materially impacted the change in revenue for the periods presented.

Gross profit decreased by $7.2 million, or 27.5%, in 1996 as compared to 1995.
Gross profit as a percentage of sales also decreased during 1996 to 41.6.%
versus 45.0% in 1995. The primary reason for this decrease in margin dollars for
1996 was due to the overall decrease in revenues versus 1995. The decrease in
the margin percentage was primarily due to the change in the product mix sold in
1996 versus 1995; from high-end to mid-range surface mount technology products
which carry a lower gross profit margin, as well as lower absorption of overhead
costs in 1996.

Selling, general and administrative expenses decreased in 1996 by $1.5 million,
or 9.4%, but increased as a percentage of net sales to 30.8% compared to 26.7%
in 1995 as a result of the 1996 sales decline. The lower costs in 1996 are
primarily the result of: $1.3 million in decreased commissions related to the
lower sales level; and a $0.5 million decrease in employee profit sharing costs
and executive bonuses, commensurate with the Company's lower overall profit
levels.


                                                                          Page 7

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Research, development and engineering expenses in 1996 decreased by $0.4
million, or 9.8%, but increased as a percentage of net sales to 8.4% compared to
7.3% in 1995. The decrease in overall spending was related to the costs
associated with the timing of new product development and introduction. The
Company continues to pursue new developments in order to support a growing
customer base.

Interest income increased by $71,000 in 1996 compared to 1995. This increase in
interest income is due to the investment of additional cash resulting from the
sale of the Company's investment in Bruce Technologies International Inc. (BTI)
in June 1996.

On June 8, 1996 the Company sold its 19.4% investment in BTI for $ 7,000,000,
resulting in a pretax gain of $ 3,400,000, net of direct costs.

Income taxes decreased in 1996 by $393,000 compared to 1995. This decrease is
directly related to the decrease in income before income taxes generated by the
lower sales level in 1996. The Company has recorded an effective tax rate during
1996 of 17.5%, as compared to an effective tax rate of 18.2% during 1995. These
compare to the statutory rate of 34%. During 1996 and 1995, the Company has
recorded the benefit of net operating losses utilized, resulting in the lower
effective tax rates.



1995 COMPARED TO 1994

During 1995, sales increased to $58.3 million, representing an increase of $15.0
million, or 34.5%, over 1994. Although the Company saw increases in sales for
most products, the more significant gains were realized in its solder reflow
systems used to mount components on PC boards using Surface Mount Technology
(SMT), which accounted for most of the overall increase. Geographically, sales
in all regions increased in 1995.

Gross profit as a percentage of sales decreased slightly during 1995 to 45.0%
versus 46.3% in 1994. The primary reason for this decrease was a shift in our
product mix during 1995, with the introduction of low- and mid-range solder
reflow systems.

Selling, general and administrative expenses increased in 1995 by $2.9 million,
or 22.7%, but decreased significantly as a percentage of net sales to 26.7%
compared to 29.3% in 1994. The higher costs in 1995 are primarily the result of:
increased commissions related to the higher sales level; and a increase in
employee profit sharing costs and executive bonuses, commensurate with the
Company's higher overall profit levels.

Research, development and engineering expenses in 1995 increased by $0.6
million, or 17.4%, but decreased slightly as a percentage of net sales by 1.1%,
to 7.3%, compared to 1994. The increase in overall spending was related to
development efforts at the Company for the SMT products, conveyor and high
temperature systems, software and control systems and for the development of new
processes for existing furnaces.

Interest income increased by $85,000 in 1995 compared to 1994. This increase in
interest income is a direct result of the higher interest rates available during
1995 compared to 1994.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


LIQUIDITY AND CAPITAL RESOURCES

During 1996, the Company sold it's 19.4% investment in BTI for $7,000,000 before
taxes. This transaction contributed significantly to the increase in the cash
balance during 1996 to $10.2 million from $6.1 million at the end of 1995.

The Company has an unsecured revolving line of credit with a bank, which allows
for aggregate borrowings and/or letters of credit of up to $5,000,000.
Borrowings are available to the Company at either the Bank's base rate or a
Eurodollar rate, as elected by the Company. This loan agreement is available to
the Company until July 1, 1998, subject to certain financial covenants. In
addition, the Company established a secured equipment loan facility with the
same bank, with the ability to borrow up to $1,000,000 for purchases of
equipment. The proceeds of these equipment loans can fund up to 75% of the cost
of qualifying equipment purchases, collateralized by a first security interest
on the purchased equipment. These equipment loans are subject to interest at
either the Bank's base rate or a Eurodollar rate, and must be repaid in monthly
principal and interest payments over a period not to exceed seven years. No
amounts were outstanding under either of these loan agreements as of December
31, 1996.

The Company has a mortgage note, which is secured by its land and building. This
mortgage had an outstanding balance at December 31, 1996 of $5,664,000, an
annual interest rate of 9%, and a balloon payment of $5,585,000 due at maturity
on April 1, 1997. Subsequent to December 31, 1996, this mortgage was refinanced
with the same institution. The terms of the new agreement are a seven year
mortgage note with a 15 year amortization payable at an annual interest rate of
8.125%, maturing on April 1, 2004 with a balloon payment of $ 3,797,000 due at
maturity.

During 1996, the Company has invested approximately $ 950,000 in capital
equipment, primarily in the areas of computer hardware, computer software and
machinery and equipment. The Company does not presently have any outstanding
commitments for capital expenditures that would have a material impact on the
Company's liquidity and future capital resources.

The Company expects that its current cash position, ability to borrow necessary
funds, as well as cash flows from operations will be sufficient to meet its
corporate, operating and capital requirements into 1998.


OTHER MATTERS

The impact of inflation and the effect of foreign exchange rate changes during
1996 has had an immaterial impact on the Company's business and financial
results.

Note 1:  Summary of Significant Accounting Policies

   a.  Nature of Operations

       BTU International, Inc. (the Company) and its wholly owned subsidiaries
       are primarily engaged in the manufacture, sale, installation and service
       of thermal processing systems, which are used as capital equipment in
       various manufacturing processes, primarily in the electronics industry.

   b.  Principles of Consolidation and the Use of Estimates

       The accompanying consolidated financial statements include the accounts
       of the Company and its wholly owned subsidiaries. All material
       intercompany balances and transactions have been eliminated in
       consolidation. The preparation of these financial statements required the
       use of certain estimates by management in determining the entity's
       assets, liabilities, revenue and expenses. Actual results may vary from
       these estimates.

   c.  Cash and Cash Equivalents

       The Company has classified certain liquid financial instruments, with
       original maturities of less than three months, as cash equivalents.

   d.  Inventories

       Inventories consist of material, labor and overhead and are valued at the
       lower of cost or market. Cost is determined by the first-in, first-out
       (FIFO) method for all inventories.

   e.  Property, Plant and Equipment

       The Company provides for depreciation using the straight-line method over
       a period sufficient to amortize the cost of the asset over its useful
       life. The estimated useful lives for depreciation purposes are as
       follows:

       Buildings and improvements           8-25     years
       Machinery and equipment               2-8     years
       Furniture and fixtures                5-8     years

       Maintenance and repairs are charged to operations as incurred. When
       equipment and improvements are sold or otherwise disposed of, the asset

   f.  Income Taxes

       The Company complies with the requirements of Statement of Financial
       Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes." Under
       SFAS No. 109, deferred tax assets and liabilities are recognized for the
       expected future tax consequences of events that have been included in the
       consolidated financial statements or tax returns. The amounts of deferred
       tax assets or liabilities are based on the difference between the
       financial statement and tax basis of assets and liabilities using enacted
       tax rates in effect for the year in which the differences are expected to
       reverse.

   g.  Translation of Foreign Currencies

       Foreign currencies are translated in accordance with SFAS No. 52,
       "Foreign Currency Translation." Under this standard, assets and
       liabilities of the Company's foreign operations are translated into
       United States dollars at current exchange rates. Income and expense items
       are translated at average rates of exchange prevailing during the year.
       Gains and losses arising from translation are accumulated as a separate
       component of stockholders' investment. Exchange gains and losses (if any)
       arising from transactions denominated in foreign currencies are included
       in income as incurred. No such exchange gains or losses were incurred in
       the periods presented.

   h.  Patents

       The Company has patents for certain of its products and processes. No
       value has been assigned to these patents in the accompanying consolidated
       financial statements.

   i.  Revenue Recognition

       Revenue is recognized based upon shipment of product to the customer,
       except for large contracts that are not completed within the normal
       operating cycle of the business. The Company recognizes revenues on these
       contracts as costs are incurred in the proportion that costs incurred
       bear to total estimated costs. Amounts related to such contracts included
       in net sales are $1,361,000, $1,102,000 and $1,117,000 for the years
       ended December 31, 1996, 1995 and 1994, respectively.

   j.  Research, Development and Engineering

       Research, development and engineering costs are charged to expense as
       incurred.

   k.  Per Share Information

       Net income per share in 1996, 1995 and 1994 was calculated based on the
       weighted average number of common and common equivalent shares
       outstanding during the year, using the treasury stock method. Fully
       diluted earnings per share are not materially different from primary
       earnings per share.

   l.  Reclassification

       Certain prior year financial statement information has been reclassified
       to conform with the current year presentation.

       The Company has an unsecured revolving line of credit, with a US bank,
       which allows for aggregate borrowings and/or letters of credit of up to
       $5,000,000 at either the Bank's base rate or a Eurodollar rate. This loan
       agreement is available to the Company until July 1, 1998, subject to the
       maintenance of certain financial covenants that, among other things,
       require the Company to meet certain net worth, debt service and current
       ratio requirements. At December 31, 1996, the Company was in compliance
       with all covenants of this agreement. In addition, the Company has a
       secured equipment loan facility with the same bank for purchases of up to
       $1,000,000 of equipment with interest at either the Bank's base rate or
       at a Eurodollar rate. The equipment loans can fund up to 75% of the cost
       of qualifying equipment purchases, collateralized by a first security
       interest on the purchased equipment, and must be repaid in monthly
       principal and interest payments over a period not to exceed seven years.
       As of December 31, 1996 and 1995, no amounts were outstanding under
       either the unsecured revolving line of credit or the equipment loan
       facility.

       The Company conducts its UK operations in a facility that is under a
       long-term operating lease expiring in 2010. Rent expense under this lease
       was approximately $ 145,000 in 1996, $205,000 in 1995 and $249,000 in
       1994. In 1994, the Company sublet a portion of this leased space. The
       initial term of the sublease is five years. Under the terms of the
       sublease the Company will receive approximately $132,000 per year. At the
       end of the initial five year sublet period, the sublease can be extended
       at market rates for two subsequent and concurrent five year periods. As
       of December 31, 1996, assuming the sublease is not extended, the future
       minimum lease commitment for this facility is $3,275,000, payable as
       follows $145,000 for each year 1997 through 1999, $250,000 for the year
       2000, $280,000 for the year 2001 and $2,310,000 thereafter.


       The Company is a party to various claims arising in the normal course of
       business. Management believes the resolution of these matters will not
       have a material impact on the Company's results of operations.

       The valuation allowance relates to uncertainty surrounding the
       realization of the deferred tax assets, principally certain tax loss and
       credit carryforwards. The net change in the valuation allowance between
       1996 and 1995 is due primarily to the recognition of net operating loss
       carryforwards as they were earned in 1996. Realization is dependent on
       generating sufficient taxable income prior to expiration of the loss
       carryforwards. As of December 31, 1996, the Company had federal tax net
       operating loss carryforwards of $2,069,000, which expire beginning in
       2007. In addition, the Company has research and development and AMT
       credit carryforwards of $1,804,000, which expire beginning in 1999. The
       tax carryforwards are subject to review and possible adjustment by the
       Internal Revenue Service. Additionally, changes in ownership may limit
       the utilization of US net operating losses for tax purposes in any one
       year, deferring the use of these losses to future years. Included in
       other current assets is a refundable income tax receivable of $1,162,000.


NOTE 7:  EMPLOYEE BENEFITS

       The Company has management incentive and profit sharing plans for its
       executives and all of its employees. These plans provide for bonuses upon
       the attainment of stipulated operating income targets. Under these plans,
       no amounts were expensed in 1996, while $801,000 in expense was recorded
       for 1995 and $372,000 was recorded for 1994.

       The Company has a deferred 401(k) contribution plan that is available to
       cover all domestic employees of the Company who have met certain length
       of service requirements. Subject to non-discriminatory restrictions on
       highly compensated employees, participants can voluntarily contribute up
       to 17% of their compensation to the plan, and the Company, at its
       discretion, may match this contribution up to a stipulated percentage.
       The Company's expense under the plan was $191,000, $172,000 and $136,000
       for the years ended December 31, 1996, 1995 and 1994, respectively.


                                                                         Page 21
<PAGE>   23
NOTE 8:  PREFERRED STOCK

       The Company has three classes of preferred stock. Its Class A Cumulative
       Redeemable Preferred Stock has a par value of $1 per share and has
       2,000,000 shares authorized. During 1995, the Company redeemed the final
       567,150 shares of Class A Cumulative Redeemable Preferred Stock for
       $567,150, plus the dividends due of $283,575 related to these shares. As
       of December 31, 1996 and 1995, no shares are outstanding. Its Class AA
       Redeemable Convertible Preferred Stock has a par value of $0.01 per
       share. During 1995, all the holders of Class AA stock converted their
       shares to common shares on a one-share-for-one-share basis. As of
       December 31, 1996 and 1995, no shares are issued or outstanding. The
       Company also has authorized 5,000,000 shares of Series Preferred Stock
       with a par value of $1 per share. As of December 31, 1996 and 1995 no
       shares are issued or outstanding.


NOTE 9:  STOCK OPTION AND PURCHASE PLANS

       The Company has two stock option plans. The 1989 Stock Plan for Directors
       (1989 Plan) provides for stock options to certain directors of the
       Company. The 1993 Equity Incentive Plan (1993 Plan) provides for stock
       options for selected key employees and the Company's non-employee
       directors. Under the terms of the 1993 Plan, other stock awards can also
       be granted at the discretion of the Company's Board of Directors.

       Under each plan, options are exercisable at a price not less than fair
       market value at the date of the grants. The 1989 Plan options expire over
       seven years and the 1993 Plan options expire over periods not to exceed
       10 years. Shares available for future stock option grants, pursuant to
       these plans, are 330,763 at December 31, 1996, 449,323 at December 31,
       1995, and 447,783 at December 31, 1994.

       A summary of all stock option activity for the years ended December 31,
       1996, 1995 and 1994 is as follows:

       At December 31, 1996 the outstanding options have exercise prices ranging
       from $ 1.38 to $ 5.00 and a weighted average remaining contractual life
       of 4.4 years.

       The Company has an Employee Stock Purchase Plan. Under the terms of the
       plan, employees are entitled to purchase shares of common stock at the
       lower of 85% of fair market value at the beginning or the end of each
       six-month option period. A total of 300,000 shares has been reserved for
       issuance under this plan, of which 74,579 remain available at December
       31, 1996. During 1996, a total of 15,970 shares were purchased at prices
       ranging from $2.55 to $3.61 per share.

       The Company applies Accounting Principles Board Opinion No. 25 and
       related Interpretations in accounting for its stock option and purchase
       plans. Accordingly, no compensation cost has been recognized related to
       the plans. Had compensation cost for the plans been determined based on
       the fair value at the grant dates for the awards under these plans
       consistent with SFAS No. 123, "Accounting for Stock-Based Compensation",
       the Company's net income and net income per share would have been reduced
       to the pro forma amounts indicated below:

<TABLE>

            Income per share      As reported         $   0.49    $   0.68
                                  Pro forma               0.48        0.68
</TABLE>

       Pro forma compensation costs were estimated using the Black-Scholes
       option pricing model using the following weighted average assumptions for
       grants in 1996 and 1995, respectively: a dividend yield rate of 0 for
       each year: expected lives of 4.5 and 1.2 years; expected volatility of
       55.3% and 66.9%; and risk free interest rates of 6.2% and 6.3%. The
       weighted average fair value of options granted during 1996 and 1995 was
       $2.29 and $1.99, respectively.

       As the SFAS No. 123 presentation has not been applied to options granted
       prior to January 1, 1995, the resulting reduction in net earnings and
       earnings per share may not be representative of that to be expected in
       future years.



NOTE 10:  DISCONTINUED OPERATIONS

       On March 6, 1992, the Company concluded the sale of its Bruce Systems
       business into a joint venture with Kokusai Electric Co., Ltd., whereby
       the Company has retained a 19.4% ownership interest in Bruce Technologies
       International, Inc.. The Company's investment in BTI at December 31, 1995
       was $3,476,000, and the Company accounted for this investment under the
       cost method.

       On June 8, 1996, the Company sold its investment in BTI for $ 7,000,000.
       As a result the Company recognized a pretax gain on this investment of
       $ 3,400,000, net of direct costs.


                                                                         Page 23

NOTE 11:  RELATED PARTY TRANSACTIONS

       During 1996 and 1995, certain transactions were made between the Company
       and certain related parties, all of which were at arms length. These
       transactions included payments to one of the Company's directors for
       consulting services of $15,000 and $14,000 in 1996 and 1995,
       respectively. These consulting services were provided to aid the Company
       in developing its Far East customer market expansion. The Company also
       had related party transactions with respect to the purchase of certain
       software development and components from a company which is partially
       owned by one of the Company's key employees. The amount of contract
       software and hardware purchased from this party in the ordinary course of
       doing business was $769,000 and $818,000 in 1996 and 1995, respectively;
       as well, $81,000 and $73,000 is included in trade accounts payable on the
       Consolidated Balance Sheets at December 31, 1996 and 1995, respectively.

NOTE 13:  DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS

       The following methods and assumptions were used to estimate the fair
       value of each class of financial instrument for which it is practicable
       to estimate that value:

              a. Cash and Cash Equivalents - The carrying amount of these assets
       on the Company's Consolidated Balance Sheet approximates their fair value
       because of the short maturity of these instruments

              b. Long-term Debt and Capital Lease Obligations - The fair value
       of this long-term indebtedness as of December 31, 1996 was approximately
       $3,526,000, based on a discounted cash flow analysis, using the
       prevailing cost of capital for the Company as of that date.
