                                   (UNAUDITED)

                                  JUNE 30, 2001

1.     INTERIM FINANCIAL STATEMENTS.

       In the opinion of management, the accompanying unaudited condensed
consolidated financial statements contain all adjustments necessary to fairly
present the Company's financial position as of June 30, 2001 and the results of
operations for the three and six months ended June 30, 2001 and 2000 and cash
flows for the six months ended June 30, 2001 and 2000. The results of operations
for the three and six months ended June 30, 2001 are not necessarily indicative
of the results to be expected for the fiscal year ending December 31, 2001.

       The accounting policies followed by the Company are set forth in Note 2
to the Company's consolidated financial statements in its annual report on Form
10-KSB for the year ended December 31, 2000.

       The financial statements, with the exception of the December 31, 2000
balance sheet, are unaudited and have not been examined by independent certified
public accountants.

                                           June 30,     December 31,

3.     EARNINGS PER SHARE.

       The following table provides a reconciliation of the denominators of the
basic and diluted earnings (loss) per share computations for the Company's
reported earnings (loss):

            Adjusted weighted average common
                shares outstanding - diluted          6,707,763     6,627,680     6,696,377     6,767,530
                                                      =========     =========     =========     =========


       At June 30, 2001, 239,062 shares of common stock issuable under stock
options were outstanding, but were not included in the calculation of diluted
earnings per share because the Company incurred a net loss for the three and six
months ended June 30 2001 and, therefore, the effect would be antidilutive.

       The increase in sales of goods for the three and six month periods ended
June 30, 2001 is primarily due to increased sales of systems in Chicago. The
decline in contract research, service and license revenues for the three and six
month periods ended June 30, 2001 is primarily due to the sale of the
Optoelectronics business, as well as delays in performance by a subcontractor.

$714,000 to $1,047,000, and decreased to 82% of related revenues, for the three
months ended June 30, 2001, compared to $1,761,000 or 91% of related revenues
for the three months ended June 30, 2000. The decrease is due to a change in
product mix, and lower volume. Cost of goods sold increased $632,000 to

and revenues, compared to $1,218,000 or 39% of sales and revenues for the three

2000. The Company reported a net loss of $1,301,000 for the six months ended
June 30, 2001, compared to a net profit of $798 for the same period of 2000.

Liquidity and Capital Resources.
- -------------------------------

       To date the Company has been able to fund its operating cash requirements
using proceeds from sale of assets, operations and available lines of credit. On
July 25, 2000, the Company entered into a revolving credit agreement with the
Silicon Valley Bank, replacing its previous credit facility with the Bank. This
agreement provides for a $2 million revolving credit facility, based upon
eligible accounts receivable requirements. This line of credit has been
established to provide the Company with resources for general working capital
purposes and Standby Letter of Credit Guarantees for foreign customers. The line
is secured by all assets of the Company. At June 30, 2001, interest on the line
was at the Bank's prime

                                       9


rate plus 1/2 percent (7.25%). The line contains covenants including provisions
relating to profitability and net worth. The Company was in default of the
covenants as of June 30, 2001. Borrowings on the line are classified as a
current liability. As of June 30, 2001, the Company had $875,000 outstanding
under this revolving credit facility. The Company is currently negotiating a
renewal to this line.

       The Company believes it has sufficient resources to finance its current
operations for the foreseeable future through working capital, its existing line
of credit and available lease arrangements. Cash and cash equivalents increased
$31,000 to $7,432,000 at June 30, 2001 from $7,463,000 at December 31, 2000. To
date, there are no material commitments by the Company for capital expenditures.
At June 30, 2001, the Company's retained earnings were $1,087,000, compared to
retained earnings of $2,388,000 as of December 31, 2000. Working capital as of
June 30, 2001 decreased 12% to $7,900,000, compared to $9,025,000 as of December
31, 2000.

Recent Accounting Pronouncements.
- --------------------------------

       In January 2001, the EITF reached a consensus on Issue 00-22, ACCOUNTING
FOR "POINTS" AND CERTAIN OTHER TIME-BASED OR VOLUME-BASED SALES INCENTIVE
OFFERS, AND OFFERS FOR FREE PRODUCTS OR SERVICES TO BE DELIVERED IN THE FUTURE.
Issue 00-22 will require that certain volume-based cash rebates to customers
currently recognized as marketing costs be classified as a reduction of revenue.
The consensus is effective for the first quarter of 2001 and was not material to
our consolidated financial statements.

Impact of Inflation and Changing Prices.
- ---------------------------------------

       Historically, the Company's business has not been materially impacted by
inflation. Manufacturing equipment sales are generally quoted, manufactured and
shipped within a cycle of approximately six months, allowing for orderly pricing
adjustments to the cost of labor and purchased parts. The Company has not
experienced any negative effects from the impact of inflation on long-term
contracts. The Company's service business is not expected to be seriously
affected by inflation because its procurement-production cycle typically ranges
from two weeks to several months, and prices generally are not fixed for more
than one year. Research and development contracts usually include cost
escalation provisions.

Foreign Exchange Fluctuation.
- ----------------------------

       The Company sells only in U.S. dollars, generally against an irrevocable
confirmed letter of credit through a major U.S. bank. Therefore the Company is
not directly affected by foreign exchange fluctuations on its current orders.
However, fluctuations in foreign exchange rates do have an effect on the
Company's customers' access to U.S. dollars and on the pricing competition on
certain pieces of equipment that the Company sells in selected markets.
