INDUSTRY BACKGROUND

GROWTH IN ELECTRONICS. Demand has grown rapidly over the past few years for
increasingly sophisticated electronic devices such as notebook computers,
cellular phones, and personal digital assistants (PDAs). Other types of
electronics equipment are becoming more complex, including data communications
equipment such as switches, routers and servers, broadband access products such
as cable modems and ethernet accessories and consumer products such as
automobile electronics and digital cameras.

Integral to the growth in electronics are the advances in technology, which
result in producing smaller, lighter and less expensive end products. These
advances are achieved, in part, by increasing the performance and reducing the
cost, size, weight and power requirements of the components that comprise
electronic devices, such as electronic assemblies, PCBs and semiconductors. In
response to these developments, OEMs and EMS providers are increasingly
employing more sophisticated manufacturing and assembly techniques and more
advanced manufacturing equipment.

ELECTRONICS MANUFACTURING PROCESS. Electronics manufacturing processes
include integrated circuit manufacturing, integrated circuit packaging and the
assembly of PCBs. In the advanced semiconductor packaging and PCB assembly
processes, several precision thermal processes are required to connect and bond
integrated circuits (ICs) to semiconductor packages and packaged circuits and
other components to PCBs. The attachment process, which creates a permanent
physical and electrical bond, is called solder reflow, or reflow. For example,
the PCB assembly process involves heating a PCB upon which solder pads have been
printed and electronic components have been placed. A convection thermal
processing system heats the PCB until just above the melting point of the solder
pads and then provides a controlled cooling cycle, resulting in a permanent
physical and electrical bond between the PCB and the electronic components.
Flux, which is produced by vaporized solder during the solder reflow thermal
processing cycle, must be contained and collected. Following the bonding
process, voids must be filled with an epoxy material which is then thermally
cured.

The growth in the electronics industry is driving manufacturers to demand
more versatile, more reliable and more advanced capital equipment. Other factors
that drive the demand for advanced thermal processing systems include:

- Rapid growth in EMS providers;

- Shift to higher value added and more complex boards at EMS providers;

- High growth in manufacturing capacity for consumer and Internet
infrastructure products;

- Technological advances in semiconductor packaging and PCB assembly;

- Globalization of major electronics manufacturers;

- Emphasis on environmental protection through the use of lead-free
solders;

- Increased velocity of new product introductions.

TECHNOLOGICAL CHALLENGES

Advanced thermal processing systems present significant engineering
challenges related to temperature control, atmosphere control, product handling,
flux containment and disposal, and high system up time.

Advanced thermal processing systems maintain accurate and uniform
temperatures within their process chambers. The temperature within the process
chamber is influenced by the rate at which components are moved through the
system and the weight and density of the PCBs. In addition, the thermal
processing system's heat convection rate must be varied and controlled as
different components and PCBs are processed. The chamber must also dispense heat
uniformly across the PCBs and components at precise temperatures so that all of
the solder will reflow properly without damaging the components. Also,
components must be heated and cooled at closely preset rates in order to avoid
damage caused by thermal stress.

Another technological challenge for advanced thermal processing systems is
achieving precisely controlled atmospheric conditions within the process
chamber. In order to facilitate thermal processing without damage to components,
many advanced thermal processing systems use a substantially oxygen-free
atmosphere of nitrogen or hydrogen in their process chambers. If such gases are
used, the entry of contaminating air must be substantially eliminated, even
though the product enters and exits the system continuously from the ambient
atmosphere. Maintaining a pure and controlled atmosphere in the process chamber,
while minimizing the consumption of nitrogen or hydrogen gases in order to
reduce operating costs, presents significant engineering challenges.

Handling PCBs in advanced thermal processing systems requires highly
reliable conveyance systems that can easily be converted to process a wide
variety of products having different specifications, often on side-by-side
tracks through the process chamber. The product handling system must also fully
support different sizes of PCBs to eliminate yield loss, which could be caused
by the sagging of PCBs at elevated temperatures during the heating process.

Volatile compounds in the flux, which is vaporized during the solder reflow
thermal processing cycle, must be contained and collected so that they do not
condense in the system and damage the environment. The efficient containment,
collection and disposal of the flux are important factors in achieving high
system up time, high throughput and reliability.

The mechanical components in advanced thermal processing systems must
operate almost continuously in a demanding, elevated temperature environment
with frequent thermal cycles. The use of materials that are resistant to high
temperature and thermal stress is important to achieving high reliability.

OUR SOLUTION

We deliver a broad range of advanced thermal processing systems to serve the
needs of electronics manufacturers that require high throughput, process yields
and reliability with tightly controlled process parameters. Our systems enable
our customers to increase advanced semiconductor packaging and PCB assembly
throughput and yield by providing precise atmosphere and temperature control. In
addition to the high performance of our products, we believe the quality
standards of our organization and our worldwide service and support are
important to our success with industry leading global electronics manufacturers.

ATMOSPHERE UNIFORMITY AND CONTROL. Our advanced thermal processing systems
provide precision control over atmospheric conditions within their process
chambers by integrating our gas curtain and physical curtain technologies. Our
systems are capable of excluding virtually all oxygen from the reflow and curing
process steps to maintain the integrity of the process chamber atmosphere. In
addition, our systems minimize the consumption of nitrogen or hydrogen, thereby
reducing the operating cost of maintaining the atmosphere.

ACCURATE AND UNIFORM TEMPERATURE. Our high rate convection heating modules
provide controlled heating capacities across many different sizes of PCBs,
thereby enabling our customers to maximize throughput regardless of their
product mix. In addition, our systems apply heat uniformly across each PCB and
its semiconductor and other components, which is critical to ensure that
complete reflow occurs. Heat up and cool down profiles are also closely
controlled for process consistency and the protection of component parts.


2


REPEATABILITY FROM SYSTEM TO SYSTEM. We provide a high degree of
repeatability from system to system through our closely characterized atmosphere
and temperature controls and the reliability of our systems. This is a critical
attribute because our customers must achieve uniform manufacturing performance
in plants located throughout the world.

PROCESSING FLEXIBILITY. Major electronics manufacturers process many sizes
of PCBs and often need rapid product changeover capabilities. Our systems can
process PCBs of different sizes with minimal or no reconfiguration. Rapid
changeover reduces down time and increases manufacturing volume. In addition,
due to their very high volume requirements, our customers may require the
ability to process multiple PCBs simultaneously side by side through the same
process chamber. Our systems afford our customers the flexibility to achieve
side-by-side processing.

RELIABILITY. Our customers place a high premium on reliability. Reliability
is a major contributor to low cost of ownership because high up time can
increase the productivity of an entire production line. We believe our advanced
thermal processing systems are the most reliable in our customers' production
lines and among the most reliable advanced thermal processing systems in the
electronics industry.

WORLDWIDE CUSTOMER SUPPORT. We provide our customers with global technical
service support, in depth process engineering support and fast delivery of our
systems and parts. We provide our customer support through our on-site direct
service organization and our independent sales and service representatives,
supplemented with telephonic support and extensive customer training programs
twenty-four hours a day, seven days a week.

PRODUCTS

We supply a broad range of advanced thermal processing systems, the majority
of which are used by OEMs and EMS providers in the electronics manufacturing
industry. The major applications for our products is currently in the PCB
assembly industry for solder reflow, and in advanced thermal processing systems
used in the bonding process necessary for the manufacture of advanced
semiconductor packages and PCB assemblies. In addition, our products are used
for such custom applications as the sintering of ceramics, the brazing of metals
and the deposition of thin film coatings.

ELECTRONICS MANUFACTURING

INTELLECTUAL PROPERTY

We seek to protect our intellectual property by filing patents on
proprietary features of our advanced thermal processing systems and by
challenging third parties that we believe infringe on our patents. We also
protect our intellectual property rights with nondisclosure and confidentiality
agreements with employees, consultants and key customers and with our
trademarks, trade secrets and copyrights. As a global supplier of equipment, we
recognize that the laws of certain foreign countries may not protect our
intellectual property to the same extent as the laws of the United States.

We license some software programs from third party developers and
incorporate them into our products. Generally, these agreements grant us
non-exclusive licenses to use the software and terminate only upon a material
breach by us. We believe that such licenses are generally available on
commercial terms from a number of licensors.

BACKLOG

Backlog as of December 31, 2001 was $8.0 million, compared to $13.7 million
as of December 31, 2000. As of December 31, 2001, we expected to ship our
year-end backlog within 6 to 40 weeks. Most of our backlog for solder reflow
systems are expected to be shipped within 3 to 8 weeks. The backlog of our
custom systems are expected to be shipped within 12 to 40 weeks. We include in
backlog only those orders for which the customer has signed a purchase order and
a delivery schedule has been specified. Because of possible changes in delivery
schedules and order cancellations, our backlog at any particular date is not
necessarily representative of sales for any subsequent period.

COMPETITION

Several companies compete with us in selling advanced thermal processing
systems to OEMs and EMS providers. Although price is a factor in buying
decisions on price, we believe that technological leadership, process
capability, throughput, environmental safeguards, uptime, mean time-to-repair,
cost of ownership and after-sale support have become increasingly important
factors. We compete primarily on the basis of these criteria, rather than on the
basis of price.

Our principal competitors for advanced semiconductor packaging and PCB
assembly equipment vary by product application. Our principal competitors for
solder reflow systems are Electrovert-Speedline Technologies (a Cookson
Electronic Company), Heller Industries, and Vitronics-Soltec, Inc. (a Dover
Technologies Company). Our high temperature systems for thick film, hybrid
circuits, ceramics and other applications compete primarily against systems sold
by Lindberg (a Unit of SPX Corp.), SierraTherm Production Furnaces, Inc.,
Centrotherm and Harper International Corp.

EMPLOYEES

As of March 1, 2002, we had 221 employees, of whom 77 are engaged in sales,
marketing and service, 23 in research, development and engineering, 22 in
finance and administration and 99 in operations. None of our employees are
represented by a collective bargaining agreement, and we believe that we have
satisfactory relations with our employees.

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 2002.

ITEM 2. PROPERTIES

FACILITIES

We maintain our headquarters in North Billerica, Massachusetts, where we own
a 150,000 square foot manufacturing facility. We currently operate our
manufacturing facility on a full time first shift and a partial second shift
basis. In England, we lease a facility for our European sale and service
operations. We also rent office space in Paris, France. In Asia, we lease sales

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

OVERVIEW

We design, manufacture, sell and support advanced thermal processing systems
used primarily in the assembly of PCBs and in advanced semiconductor packaging.
We believe we are the leading supplier of solder reflow systems used by OEMs and
EMS providers. In addition, we produce advanced high temperature processing
systems for manufacturing ceramic components for electronic devices and a
variety of specialty applications.

We derive our net sales from customers around the world. Our customers
include large multinational OEMs and EMS providers requiring advanced thermal
processing equipment solutions. In 2001, net sales to our five largest customers
accounted for 26.1% of our total net sales. Our net sales in 2001 were dispersed
worldwide, with approximately 41.0% to customers in the United States, 28.0% to
Asia Pacific customers, 25.0% to European customers and 6.0% to Other Americas.
Over the past three years, the percentage of our net sales to international
customers was 68.0% in 1999, 66.0% in 2000 and 59.0% in 2001. These percentages
reflect an emphasis on offshore manufacturing by our U.S.-based multinational
customers and the successful penetration of new non-U.S. based customers.

CRITICAL ACCOUNTING POLICIES

The following is a discussion of those accounting policies that the Company
deems to be "critical" - that is, they are important to the portrayal of the
Company's financial condition and results, and they reflect management's
reliance on estimates regarding matters that are inherently uncertain.

REVENUE RECOGNITION ON LONG-TERM AGREEMENTS - The Company regularly enters
into sales transactions projects that take longer than the normal business cycle
to complete. The Company accounts for these projects on a percentage completion
basis. Using this method, revenues are recognized based on the ratio of costs
incurred to the project's total estimated costs. To the extent that the
Company's estimates regarding costs or time required for completion prove to be
materially inaccurate, the Company's revenues for a period may likewise be
materially different. The Company routinely reviews estimates relating to these
projects, and regularly revises the estimates when necessary to reflect a change
in outlook. Revisions to cost estimates result in a charge to revenues for the
period in which the facts leading to the revision become known. Adjustments to
revenues based on revisions to estimates under long-term agreements were
insignificant for each of the three years ending December 31, 2001.

For more information on the Company's general revenue recognition
policies, please see Note 1 to the financial statements included in this report.

INVENTORY VALUATION - The Company's inventories consist of material, labor
and manufacturing overhead costs. The Company determines the cost of inventory
based on the first-in, first-out method (FIFO). The Company regularly reviews
the quantity of inventories on hand and compares these quantities to the
expected usage of each applicable product or product line. The Company's
inventories are regularly adjusted in value to the lower of costs and/or net
realizable value. Since the value of the Company's inventories depends in part
on the Company's estimates of each product's net realizable value, adjustments
may be needed to reflect changes in valuation. Any adjustments the Company is
required to make to lower the value of the inventories are recorded as a charge
to cost of revenue.

RESULTS OF OPERATIONS

The following table sets forth the percentage of net sales of certain items
in our consolidated financial statements for the periods indicated.

===== ===== ======


FISCAL YEAR ENDED DECEMBER 31, 2001 AS COMPARED TO FISCAL YEAR ENDED
DECEMBER 31, 2000

Net Sales. Net sales decreased 52.7% from $99.5 million in 2000 to $47.1
million in 2001. The decrease in 2001 net sales reflects the lower demand for
our products, primarily by our large multinational EMS providers. This decrease
in net sales also reflects the slow down in the electronics manufacturing
market.

The growth in the percentage of net sales to United States customers
reflects the increase in the percentage of sales made to our OEM providers. The
decrease in net sales to European and Asia Pacific customers reflects the
decline in net sales to our EMS providers. The percentage of net sales
attributable to our customers in the United States increased in 2001 by 7.2%,
net sales attributable to our customers in Europe decreased by 2.6%, net sales
attributable to our Asia Pacific customers decreased by 3.7% and net sales
attributable to our customers in the other Americas decreased by 0.9% as
compared to 2000. The effect of price changes for specific products has not
materially impacted the change in net sales for the periods presented.

10


Gross Profit. Gross profit decreased 61.8% from $40.4 million in 2000 to
$15.4 million in 2001 and, as a percentage of net sales, decreased from 40.6% in
2000 to 32.8% in 2001. The decrease in gross profit and gross profit percentage
for 2001 was due to the decrease in net sales in 2001 and the under absorption
of overhead.

Selling, General and Administrative. Selling, general and administrative
costs decreased 35.5% from $25.3 million in 2000 to $16.3 million in 2001, and
as a percentage of net sales, increased from 25.4% to 34.7%. Lower costs were
incurred for every area of selling, general and administrative including sales,
service and commissions and administrative costs.

Research, Development and Engineering. Research, development and engineering
costs decreased 19.7% from $6.2 million in 2000 to $5.0 million in 2001, and as
a percentage of net sales, increased from 6.3% in 2000 to 10.6% in 2001. A large
percentage of our research, development and engineering expense in 2001 was
spent on the development of a new solder reflow platform and in support of
custom design solutions.

Operating Income. Operating income decreased 166.7% from an operating income
of $8.8 million in 2000 to an operating loss of $(5.9) million in 2001, and as a
percentage of net sales, operating income decreased from an 8.9% profit in 2000
to a (12.5)% operating loss in 2001. In 2001, the decrease in operating income
was the result of a 52.7% decrease in net sales compared to 2000.

Other income (expense), net. During 2000, the Company initiated a plan to
sell an additional 2.5 million shares of common stock in a secondary offering.
The Board of Directors voted to withdraw the stock offering as market conditions
were unfavorable to proceed. In 2000 the Company incurred approximately $450,000
in costs associated with this proposed sale of stock.

Income Taxes. Income taxes decreased from a $2.9 million provision in 2000
to a $2.2 million benefit in 2001. Our effective tax provision and benefit rates
were 35.0% in 2000 and 37.0% in 2001.


FISCAL YEAR ENDED DECEMBER 31, 2000 AS COMPARED TO FISCAL YEAR ENDED
DECEMBER 31, 1999

Net Sales. Net sales increased 39.6% from $71.3 million in 1999 to $99.5
million in 2000. The increase in 2000 net sales reflects the higher demand for
our products, primarily by our large multinational OEMs and EMS providers. This
increase in net sales also reflects growth of approximately 20.0% in the
electronics manufacturing market and the gain in market share we have achieved
with our medium and high end solder reflow systems.

The percentage of net sales attributable to our customers in the United
States increased by 2.5%, net sales attributable to our customers in Europe
increased by 0.8%, net sales attributable to our Asia Pacific customers
increased by 1.8% and net sales attributable to our customers in the other
Americas decreased by 5.1%. The growth in net sales to United States customers
reflects the continued increase in EMS providers market share. The growth in net
sales to European and Asia Pacific customers reflects the trend toward offshore
manufacturing by our U.S.-based and multinational customers and our increased
sales to overseas domestic manufacturers. The effect of price changes for
specific products has not materially impacted the change in net sales for the
periods presented.

Gross Profit. Gross profit increased 40.2% from $28.8 million in 1999 to
$40.4 million in 2000 and, as a percentage of net sales, increased from 40.4% in
1999 to 40.6% in 2000. The increase in gross profit and gross profit percentage
for 2000 was due to the increase in net sales in 2000.

Selling, General and Administrative. Selling, general and administrative
increased 24.8% from $20.3 million in 1999 to $25.3 million in 2000, and as a
percentage of net sales, decreased from 28.5% to 25.4%. The higher costs in 2000
were primarily the result of a $28.2 million increase in our net sales. The
higher selling, general and administrative in 2000 can be attributed to an
increase in customer service support for our worldwide customer base and higher
selling expenses. In 2000, sales commission expense was higher as sales
increased. In addition, higher bonuses were recorded in 2000 compared to 1999,
due to the increase in net income. In 2000 the Company's net warranty costs were
favorably impacted by $246,000 through a cost sharing program.

Research, Development and Engineering. Research, development and engineering
increased 30.2% from $4.8 million in 1999 to $6.2 million in 2000, and as a
percentage of net sales, decreased from 6.7% in 1999 to 6.3% in 2000 A large
percentage of our research, development and engineering expense in 2000 was
spent on the development of a new solder reflow platform and in support of
custom design solutions.

11


Operating Income. Operating income increased 136.3% from $3.7 million in
1999 to $8.8 million in 2000, and as a percentage of net sales, increased from
5.2% in 1999 to 8.9% in 2000. In 2000, the increase in operating income was the
result of a 39.6% increase in net sales over 1999. In addition, we increased
efficiencies throughout the organization and our cost structure for sales,
general and administrative and research, development and engineering increased
at a lower rate than did the net sales percentage.

Other income (expense), net. During the first half of 2000, the Company
initiated a plan to sell an additional 2.5 million shares of common stock in a
secondary offering. The Board of Directors voted to withdraw the stock offering
as current market conditions were unfavorable to proceed. The Company incurred
approximately $450,000 in costs associated with this proposed sale of stock,
which were subsequently expensed during the quarter ending December 31, 2000.

Income Taxes. Income taxes increased from $935,000 in 1999 to $2,925,000 in
2000. Our effective tax rates were 24.8% in 1999 and 35.0% in 2000. . During
1999 we recorded the benefit of net operating loss carryforwards available to
our UK subsidiary, which was profitable in 1999, resulting in the lower
effective tax rates. Our statutory federal income tax rate is 34.0%.

LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 2001, we had $15.7 million in cash and cash equivalents,
an increase of $6.8 million compared to December 31, 2000. The increase was
primarily a result of collections on accounts receivable.

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 $14,000,000.
Borrowings are available to the Company at either the Bank's base rate or a
Eurodollar rate, as elected by the Company. This loan facility is available to
the Company until April 30, 2004, subject to compliance with certain financial
covenants. As of December 31, 2001, no amounts were outstanding under this
unsecured revolving line of credit. At December 31, 2001, the Company was not in
compliance with certain financial covenants of this agreement. The bank and the
Company have agreed on revised financial covenants requiring an amendment to the
loan facility, which is in process.

We have a mortgage note that is secured by our real property. The mortgage
note had an outstanding balance at December 31, 2001 of approximately $4.6
million. The mortgage requires monthly payments of $53,922, which includes
interest calculated at the rate of 8.125% per annum. A final balloon payment of
approximately $3.8 million is due on July 1, 2004 upon maturity of the mortgage
note.

We expect that our current cash position and ability to borrow necessary
funds will be sufficient to meet our corporate, operating and capital
requirements into 2003.

MARKET RISK DISCLOSURE

Our primary market risk exposure is in the area of foreign currency exchange
rate risk. We are exposed to currency exchange rate fluctuations as they pertain
to invoices for parts and labor in our foreign service locations.

As of December 31, 2001, all of our long-term debt and capital lease
obligations are fixed rate financial instruments. Therefore we are not exposed
to interest rate risk resulting from variable interest rate of our debts.

OTHER MATTERS

The impact of inflation and the effect of foreign exchange rate changes
during 2001 have not had a material impact on our business and financial
results.

RECENT ACCOUNTING DEVELOPMENTS

In July 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 141, "Accounting for Business Combinations," and SFAS No. 142, "Goodwill and
Other Intangible Assets." These statements modify accounting for business
combinations after September 30, 2001 and will affect the Company's treatment of
goodwill and other intangible assets at the start of the year 2002, and for
acquisitions consummated after June 30,2001.The statements require that goodwill
existing at the date of adoption be reviewed for possible impairment and that
impairment tests be periodically repeated, with impaired assets written down to
fair value. Additionally, existing goodwill and intangible assets must be
assessed and classified with the statement's criteria. Intangible assets with
estimated useful lives will continue to be amortized over those periods.
Amortization of goodwill and intangible assets with indeterminable lives will
cease. The Company does not expect the adoption of this statement to have a
material impact on its results of operations because the Company currently does
not have any goodwill.

In June 2001, the FASB issued SFAS No.143, "Accounting for Asset Retirement
Obligations." SFAS 143 addresses financial accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs. This statement applies to legal obligations
associated with the retirement of long-lived assets that result from the
acquisition, construction, development and/or the normal operation of a
long-lived asset, except for certain obligations of lessees. This statement does
not apply to obligations that arise solely from a plan to dispose of a
long-lived asset. This statement is effective for financial statements issued
for fiscal years beginning after June 15, 2002. The Company does not expect the
adoption of this statement to have a material impact on its results of
operations.

In August 2001, the FASB issued SFAS No. 144,"Accounting for the Impairment
or Disposal of Long-Lived Assets." SFAS 144 addresses financial accounting and
reporting for the impairment or disposal of long-lived assets. This statement
requires that a long-lived asset to be abandoned, exchanged for a similar
productive asset, or distributed to owners in a spin-off be considered held and
used until it is disposed of. The changes in this statement require that one
accounting model be used for long-lived assets to be disposed of by sale,
whether previously held and used or newly acquired, and by broadening the
presentation of discontinued operations to include more disposal transactions.
The provisions of this statement are effective for financial statements issued
for fiscal years beginning after December 15, 2001 and interim periods within
those fiscal years, with early application encouraged. The provisions of this
statement generally are to be applied prospectively. The Company does not expect
the adoption of this statement to have a material impact on its results of
operations.

===== ===== ===== ===== ===== ===== ===== =====


During the eight quarters in 2000 and 2001, net sales decreased from a high
of $26.9 million to a low of $7.3 million. The overall decline in net sales for
2001 is the result of a continual decline in the electronics manufacturing
marketplace.

Gross profits as a percentage of net sales during the last eight quarters
began at 42.0% and ended at 33.4%. The decline in gross profit and gross profit
as a percent of net sales during 2001 was due to the decrease in net sales and
the under absorption of overhead.

Selling, general and administrative costs during the last eight quarters of
2000 and 2001 decreased from a high of $6.7 million to a low of $3.3 million.
Lower costs were incurred in every area of selling, general and administrative
for 2001 including sales, service and commission costs.

Research, development and engineering costs decreased in real terms but
increased as a percentage of net sales from 2000 to 2001 due to the decrease in
net sales for 2001.

Income from operations decreased during the eight quarters in 2000 and 2001
from a high income of $2.5 million to a loss of $(2.4) million. The loss from
operations for the year 2001 was the result of the decrease in net sales over
2000.

Other income (expense), net includes approximately $450,000 in the fourth
quarter of 2000 in costs associated with the proposed sale of stock which was
withdrawn due to unfavorable market conditions.

BTU INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2001, 2000 AND 1999

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

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

PRINCIPLES OF CONSOLIDATION AND THE USE OF ESTIMATES

The accompanying consolidated financial statements include the accounts of
the Company. All material intercompany balances and transactions have been
eliminated in consolidation. The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities, disclosure of contingent assets and liabilities at the date of the
financial statements, and the reported amounts of revenues and expenses during
the reporting periods. The primary estimates used in the consolidated financial
statements include percent complete revenue and inventory reserves.

CASH AND CASH EQUIVALENTS

The Company has classified certain liquid financial instruments, with
original maturities of less than three months, as cash equivalents. These
financial instruments are carried at cost, which approximates fair value.

INVENTORIES

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

Inventories consist of the following (in thousands):

YEARS ENDED
DECEMBER 31,
-------------------
2001 2000
------- -------
Raw materials and manufactured components........... $ 4,903 $ 6,004
Work-in-progress.................................... 3,026 5,552
Finished goods...................................... 1,122 2,063
------- -------
$ 9,051 $13,619
======= =======

The Company periodically reviews quantities of inventory on hand and
compares these amounts to expected usage of each particular product or product
line. The Company records, as a charge to cost of revenue, any amounts required
to reduce the carrying value of the inventory to net realizable value.

PROPERTY, PLANT AND EQUIPMENT

The Company provides for depreciation using the straight-line method over
the assets' useful lives. 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 cost and
accumulated depreciation are removed from the accounts, and the resulting gain
or loss, if any, is included in the results of operations.

19


INCOME TAXES

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.

TRANSLATION OF FOREIGN CURRENCIES

Assets and liabilities of the Company's foreign operations are translated
from their functional currency into United States dollars at year end exchange
rates. Revenue and expense items are translated at weighted average rates of
exchange prevailing during the year. Gains and losses arising from translation
are accumulated as a separate component of stockholders' equity, as the
functional currency of the subsidiaries is their local currency, and the
reporting currency of the Company is the US dollar. Exchange gains and losses
(if any) arising from transactions denominated in foreign currencies are
included in income as incurred. Such exchange gains or losses were not material
during the periods presented.

PATENTS

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

REVENUE RECOGNITION

Prior to 2000, the Company generally recognized revenues upon shipment of
its products. During the fourth quarter of 2000, effective as of January 2,
2000, the Company adopted Securities and Exchange Commission (SEC) Staff
Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial
Statements." Under SAB No. 101, when the terms of sale include customer
acceptance provisions, and compliance with those provisions can not be
demonstrated until customer use, revenues are recognized upon acceptance.
Furthermore, revenues for products that require installation for which the
installation is essential to functionality or is not deemed inconsequential or
perfunctory are recognized upon completion of installation. Revenues for
products sold where installation is not essential to functionality and is deemed
inconsequential or perfunctory are recognized upon shipment with estimated
installation and warranty costs accrued. The adoption of SAB No. 101 had no
impact on the Company's previously recorded revenue.

Applying the requirements of SAB No. 101 to future sales arrangements used
in the Company's thermal processing equipment sales may result in the deferral
of the revenue for some equipment sales. The Company continues to evaluate the
impact that SAB No. 101 might have on its sales transactions. However, there
will be no impact on the Company's cash flows from operations as a result of any
change.

The Company also has certain sales transactions for projects, which are not
completed within the normal operating cycle of the business. These contracts are
accounted for on a percentage completion basis. Under the percentage completion
method, revenues are recognized based upon the ratio of costs incurred to the
total estimated costs. Revisions in costs and profit estimates are reflected in
the period in which the facts causing the revision become known. Provisions for
total estimated losses on uncompleted contracts are made in the period in which
such losses are determined. For the year ended December 31, 2001, $3.4 million
of revenue was recognized using the percentage of completion method for systems
not yet shipped. For the years ended December 31, 2000 and 1999 there was no
revenue recognized using the percentage of completion method for systems not yet
shipped. Revenue recognized on the percentage of completion method included in
net sales, as a percent of net sales, during each year was 14.1% for 2001, 1.0%
for 2000 and 2.3% for 1999.

Amounts billed to customers for shipping and handling costs have been
reclassified as revenues with the associated costs reported as selling costs.
Previously, amounts billed to customers for shipping and handling had generally
been reported as an offset to the related cost. This is in compliance with
Emerging Issues Task Force (EITF) issued 00-10 "Accounting for Shipping and
Handling Fees and Cost".

RESEARCH, DEVELOPMENT AND ENGINEERING

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

20


EARNINGS PER SHARE INFORMATION

Basic Earnings Per Share (EPS) is computed by dividing income available to
common stockholders by the weighted-average number of common shares outstanding
during the period. Diluted EPS is computed using the weighted average number of
common and dilutive potential common shares outstanding during the period, using
the treasury stock method. Options outstanding that were not included in the
determination of diluted EPS, because they were antidilutive, were 1,050,812 in
2001, 2,271 in 2000 and 289,778 in 1999.

RECENT ACCOUNTING DEVELOPMENTS

In July 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 141, "Accounting for Business Combinations," and SFAS No. 142, "Goodwill and
Other Intangible Assets." These statements modify accounting for business
combinations after September 30, 2001 and will affect the Company's treatment of
goodwill and other intangible assets at the start of the year 2002, and for
acquisitions consummated after June 30,2001.The statements require that goodwill
existing at the date of adoption be reviewed for possible impairment and that
impairment tests be periodically repeated, with impaired assets written down to
fair value. Additionally, existing goodwill and intangible assets must be
assessed and classified with the statement's criteria. Intangible assets with
estimated useful lives will continue to be amortized over those periods.
Amortization of goodwill and intangible assets with indeterminable lives will
cease. The Company does not expect the adoption of this statement to have a
material impact on its results of operations because the Company currently does
not have any goodwill.

In June 2001, the FASB issued SFAS No.143, "Accounting for Asset Retirement
Obligations." SFAS 143 addresses financial accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs. This statement applies to legal obligations
associated with the retirement of long-lived assets that result from the
acquisition, construction, development and/or the normal operation of a
long-lived asset, except for certain obligations of lessees. This statement does
not apply to obligations that arise solely from a plan to dispose of a
long-lived asset. This statement is effective for financial statements issued
for fiscal years beginning after June 15, 2002. The Company does not expect the
adoption of this statement to have a material impact on its results of
operations.

In August 2001, the FASB issued SFAS No. 144,"Accounting for the Impairment
or Disposal of Long-Lived Assets." SFAS 144 addresses financial accounting and
reporting for the impairment or disposal of long-lived assets. This statement
requires that a long-lived asset to be abandoned, exchanged for a similar
productive asset, or distributed to owners in a spin-off be considered held and
used until it is disposed of. The changes in this statement require that one
accounting model be used for long-lived assets to be disposed of by sale,
whether previously held and used or newly acquired, and by broadening the
presentation of discontinued operations to include more disposal transactions.
The provisions of this statement are effective for financial statements issued
for fiscal years beginning after December 15, 2001 and interim periods within
those fiscal years, with early application encouraged. The provisions of this
statement generally are to be applied prospectively. The Company does not expect
the adoption of this statement to have a material impact on its results of
operations.

mortgage note payable has a balloon payment of $3,825,000 due at maturity on
July 1, 2004.

The capital lease obligations relate to various equipment leases used in the
operation of the business. Under the terms of the debt, the minimum repayments
of long-term debt and capital lease obligations by year are as follows (in
thousands):

8.125% CAPITAL
MORTGAGE LEASES TOTAL

At December 31, 2001, 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 $14,000,000. Borrowings are available to the Company at either the
Bank's base rate or a Eurodollar rate, as elected by the Company. This loan
facility is available to the Company until April 30, 2004, subject to compliance
with certain financial covenants. As of December 31, 2001, no amounts were
outstanding under this unsecured revolving line of credit. At December 31, 2001,
the Company was not in compliance with certain financial covenants of this
agreement. The bank and the Company have agreed on revised financial covenants
requiring an amendment to the loan facility, which is in process.

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 $260,000 in 2001, $310,000 in 2000 and $143,000 in 1999. In 1995,
the Company sublet a portion of this leased space for a period of five years,
this sublet ended during 2000, therefore increasing the rent expense to the
Company in 2000. The Company has entered into a new lease assignment that the
Company will assign approximately $185,000 in rent expense per year starting
July 2001 through March 2010. As of December 31, 2001, the future minimum lease
commitment for this facility is $1,308,000, payable as follows: $157,000 for the
year 2002 through 2009, $52,000 for 2010.

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 or financial condition.

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 $243,000, $233,000, and $206,000 for the years ended December 31, 2001,
2000 and 1999, respectively.

(8) STOCK OPTION AND PURCHASE PLANS

The Company has three 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 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. The 1998 Stock Option Plan for Non-Employee Directors (1998 Plan)
provides for stock options to non-employee directors of the Company.

Under each plan, the exercise price of the options is 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. The
1998 Plan options expire over a period not to exceed seven years. In June 2000
the shareholders approved the addition of 750,000 shares available to be awarded
under the 1993 Plan. Shares available for future stock option grants, pursuant
to these plans, were 547,679 at December 31, 2001, 676,703 at December 31, 2000,
and 174,041 at December 31, 1999.

During 2001, the Company granted 20,000 shares of restricted stock to an
employee. This stock vests over a two year term. The Company has recorded a
compensation charge of $46,000 in 2001 related to this grant. At December 31,
2001, the unvested portion of this award was $76,000.

A summary of all stock option activity for the years ended December 31,
2001, 2000 and 1999 is as follows:

At December 31, 2001 the outstanding options have exercise prices ranging
from $2.69 to $13.63 and a weighted average remaining contractual life of 3.4
years.

The following table summarizes information for options outstanding and
exercisable at December 31, 2001:

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 500,000 shares have been reserved for issuance under this
plan, of which 185,414 remain available at December 31, 2001. During 2001, a
total of 18,163 shares were purchased at prices ranging from $3.69 to $5.19 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:

YEARS ENDED DECEMBER 31,
-----------------------------------
2001 2000 1999
--------- ------ -------
(IN THOUSANDS, EXCEPT PER SHARE DATA)

Net Income:
As reported.......................... $(3,747) $5,422 $2,838
Pro forma............................ (4,429) 4,782 2,455
Income per basic share:
As reported.......................... $ (0.54) $ 0.79 $ 0.42
Pro forma............................ (0.64) 0.70 0.36
Income per diluted share:
As reported.......................... $ (0.54) $ 0.74 $ 0.41
Pro forma............................ (0.64) 0.66 0.35

Pro forma compensation costs were estimated using the Black-Scholes option
pricing model using the following weighted average assumptions for grants in
2001, 2000 and 1999, respectively; a dividend yield rate of 0 for each year;
expected lives of 5.0, 5.0 and 4.8 years; expected volatility of 68.2%, 72.1%
and 64.6%; and risk free interest rates of 3.9%, 6.3% and 6.2%. The weighted
average fair value of options granted during 2001, 2000 and 1999 was $1.93,
$5.91 and $2.91, respectively.

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

(9) RELATED PARTY TRANSACTIONS

During 2001 and 2000, transactions were made between the Company and certain
related parties, all of which management believes were made at arms' length.
These transactions included payments to one of the Company's directors for
consulting services of $15,000 in 2001 and 2000, respectively. 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 $276,000
and $1,685,000 in 2001 and 2000, respectively; as well, $26,000 and $184,000 is
included in trade accounts payable on the Consolidated Balance Sheets as of
December 31, 2001 and 2000, respectively.

(11) 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 Sheets approximates their fair value because of
the short maturities of these instruments.

b. Long-term Debt and Capital Lease Obligations - The fair value of
long-term indebtedness as of December 31, 2001 and 2000 was approximately
$5,054,000 and $4,820,000, respectively, based on a discounted cash flow
analysis, using the prevailing cost of capital for the Company as of each date.

(12) SEGMENT REPORTING

Segments are defined as components of an enterprise about which separate
financial information is available that is evaluated regularly by the chief
operating decision-maker in deciding how to allocate resources and in assessing
performance. The Company operates as a single business segment called thermal
processing capital equipment.

The thermal processing capital equipment segment consists of the designing,
manufacturing, selling and servicing of thermal processing equipment and related
process controls for use in the electronics, power generation, automotive and
other industries. This business segment includes the supply of solder reflow
systems used for surface mount applications in printed circuit board assembly.
Thermal processing equipment is used in: low temperature curing/encapsulation;
hybrid integrated circuit manufacturing; integrated circuit packaging and
sealing; and processing multi-chip modules. In addition, the thermal process
equipment is used for sintering nuclear fuel for commercial power generation, as
well as brazing and the sintering of ceramics and powdered metals, and the
deposition of precise thin film coatings. The business segment's customers are
multinational original equipment manufacturers and contract manufacturing
companies.

The accounting policies of segment reporting are the same as those described
in Note 1 "Summary of Significant Accounting Policies." The Company evaluates
the performance of operating results taken as a whole.
