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, which were not included in the
determination of diluted EPS for the three months and nine months ended
September 28, 2003 and September 29, 2002 because they were antidilutive, were
1,110,986 and 1,119,300 respectively.

         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 loss and net loss
per share would be the pro forma amounts indicated below:

(5)      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

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
                                   (Unaudited)


(6)      Revenue Recognition

         The Company recognizes revenue in accordance with the 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 Company also has certain sales transactions for projects that are
not completed within the normal operating cycle of the business. These contracts
are accounted for on a percentage of 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, if any,
are made in the period in which such losses are determined.

         For the nine months ended September 28, 2003 there was no revenue
recognized using the percentage of completion method. For the nine months ended
September 29, 2002, $252,717 of revenue was recognized using the percentage of
completion method.

         The Company accounts for shipping and handling costs billed to
customers in accordance with Emerging Issues Task Force (EITF) Issue 00-10
"Accounting for Shipping and Handling Fees and Cost". Amounts billed to
customers for shipping and handling costs are reclassified as revenues with the
associated costs reported as cost of goods sold.

(7)      Restructuring Charges

         The Company recorded a $190,000 restructuring charge in the second
quarter 2003. This charge was solely related to severance costs associated with
the reduction of 15 non-production employees. Approximately $151,000 in
severance payments were made during the second and third quarter. The remaining
balance is included in other current liabilities and is expected to be paid
during the fourth quarter of 2003.

(8)      Acquisition

         In the second quarter of 2003, the Company acquired the assets of
Sagarus Robotics Corporation of Tempe, Arizona. The Sagarus operations have been
moved to Billerica, Massachusetts and the Sagarus products are now integrated
with the BTU worldwide product offerings. The pro-forma results, to disclose the
effects on the Company's results of operations as if the acquisition had been
completed as of the beginning of the period were not presented herein as they
are immaterial to the Company's operations.

(9)      Product Warranty Costs

         The Company provides standard warranty coverage for parts and labor for
12 months and special extended coverage on certain other parts. The reserve for
warranty covers the estimated costs of material, labor, overhead and travel.

         The Company is currently evaluating the warranty accrual activity and
the adequacy of the ending balance. In the opinion of Management, such accruals
are adequate to cover all outstanding warranty obligations.

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


RESULTS OF OPERATIONS

         Net Sales. Net sales decreased 5.1% from $7.1 million in the third
quarter of 2002 to $6.7 million in the third quarter of 2003. For the first nine
months net sales decreased 17.1% from $25.0 million in 2002 to $20.7 million in
2003. The decrease in both the third quarter and first nine months of 2003 was
primarily a result of decreases in product shipments of the Company's advanced
materials systems, whose markets have not yet rebounded.

         When comparing the third quarter of 2003 to the third quarter of 2002
the percentage of total net sales attributable to our customers in the United
States decreased by 8.4%, the percentage of total net sales attributable to our
customers in Europe decreased by 6.5%, the percentage of total net sales
attributable to our Asia Pacific customers increased by 22.3%, and the
percentage of total net sales attributable to our customer in the Other Americas
decreased by 7.4%. Comparing the first nine months of 2003 to the first nine
months of 2002 the percentage of total net sales attributable to our customers
in the United States decreased by 14.0%, the percentage of total net sales
attributable to our customers in Europe decreased by 1.6%, the percentage of
total net sales attributable to our Asia Pacific customers increased by 17.7%,
and the percentage of total net sales attributable to our customer in the Other
Americas decreased by 2.2%.

         Gross Profit. Gross profit decreased 45.3% from $2.5 million in the
third quarter of 2002 to $1.4 million in the third quarter of 2003 and, as a
percentage of net sales, decreased from 35.2% to 20.3%. For the first nine
months of 2003 gross profit decreased 41.8% from $8.2 million in 2002 to $4.8
million in 2003 and, as a percentage of net sales, decreased from 32.8% to
23.0%. The decrease in gross profit is a direct result of decreased demand for
products in the advanced materials market. The decreased demand resulted in a
product mix which has experienced significant price pressure and
under-absorption of costs in 2003.

         Selling, General and Administrative. Selling, general and
administrative expense decreased 36.5% from $3.4 million in the third quarter of
2002 to $2.2 million in the third quarter of 2003. As a percentage of net sales,
selling, general and administrative decreased from 48.0% in the third quarter of
2002 to 32.1% in the third quarter of 2003. For the first nine months of 2003,
selling, general and administrative decreased 31.0% from $10.8 million in 2002
to $7.5 million in 2003, and decreased as a percentage of net sales, from 43.4%
in the first nine months of 2002 to 36.1% for the same period in 2003. The
decreases in costs in 2003 were the result of lower expenditures for sales,
service, marketing and administrative functions, as the Company reduced its
workforce to the realities of the marketplace.

         Research, Development and Engineering. Research, development and
engineering expense decreased 17.5% from $0.9 million in the third quarter of
2002 to $0.7 million in the third quarter of 2003. As a percentage of net sales,
it decreased from 12.7% to 11.1% for the same periods. For the first nine months
of 2003 research, development and engineering expense decreased 13.3% from $2.8
million in 2002 to $2.4 million in 2003, and as a percentage of net sales
increased from 11.1% in 2002 to 11.6% in 2003. In both the third quarter and
first nine months of 2003, the Company continued support of product development,
but at reduced levels given the current economic climate.

         Restructuring Charges. In the second quarter of 2003, the Company
reduced its overhead personnel to better align its spending with the current
economic market for its products. The $190,000 restructuring charge represents
severance costs for the laid- off employees.

         Operating Loss. Operating loss decreased 29.0% from $2.2 million in the
third quarter of 2002 to $1.5 million in the third quarter of 2003 and, as a
percentage of net sales, decreased from 30.6% to 22.9%. For the first nine
months of 2003, operating loss decreased 8.3% from $5.8 million in 2002 versus
$5.3 million in 2003 and, as a percentage of net sales, increased from 23.1% to
25.5%. The decrease in operating losses in the third quarter of 2003 was
primarily the result of lower expenditures for all functions within the Company.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                      AND RESULTS OF OPERATIONS (continued)

         Income Taxes. The Company has recorded a full valuation allowance
to offset its deferred tax asset arising as a result of the Company's net
operating loss carryforward due to the uncertainty surrounding realization.
The income tax benefit reflected in the statement of operations for the nine
months ended September 28, 2003 represents an additional carryback allowance
calculated in the Company's 2002 federal income tax return. This one-time
carryback claim represents a refund of taxes paid in prior periods which the
Company received in the third quarter. Our statutory federal income tax rate
is 34.0%.

LIQUIDITY AND CAPITAL RESOURCES

         As of September 28, 2003, we had $7.7 million in cash and cash
equivalents.

         The Company has an unsecured revolving line of credit with a US bank,
which allows for aggregate borrowings, including letters of credit, up to a
maximum of $14 million against a borrowing base of all assets except real
estate. The Company may elect to borrow at interest rates pegged to either the
bank's base rate or the LIBOR rate in effect from time to time. This loan
agreement extends to May 31, 2006 and is subject to maintaining certain
financial covenants. As of September 28, 2003, no amounts were outstanding under
this unsecured revolving line of credit.

         We have a mortgage note that is secured by our real property. The
mortgage note had an outstanding balance at September 28, 2003 of approximately
$4.1 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.

         During the nine months ended September 28, 2003, the Company used cash
resources of $6.2 million. This use of cash was primarily the result of net
losses of $5.3 million and an increase in accounts receivable of $1.3 million.

         We expect that our current cash position, our ability to borrow
necessary funds and a new mortgage note, currently being negotiated, will be
sufficient to meet our corporate, operating and capital requirements into 2004.

OTHER MATTERS

         The impact of inflation and the effect of foreign exchange rate changes
during 2003 have had no material impact on our business and financial results.
