FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

In June of 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in
the fair value of derivatives are recorded each period in current earnings or
other comprehensive income, depending on whether a derivative is designated as
part of a hedge transaction and, if it is, the type of hedge transaction. The
Company adopted the provisions of SFAS No. 133 effective January 1, 2001. The
impact of adopting SFAS No. 133 was immaterial to the Company.

FOREIGN EXCHANGE RISK MANAGEMENT

In the quarter ended April 1, 2001, the Company entered into forward exchange
contracts to hedge a portion of its probable anticipated, but not firmly
committed transactions. The anticipated transactions whose risks were being
hedged were the intercompany sales of inventory by the US parent to the foreign
subsidiary payable in the foreign subsidiary's local currency. These contracts,
which related primarily to the Japanese Yen, generally had a time period of six
months. Realized and unrealized gains and losses on forward exchange contracts
that do not qualify for hedge accounting are recognized immediately in
earnings. As of April 1, 2001, the total loss incurred for this transaction was
$354,000 which did not qualify as a hedge.

The Company uses forward exchange contracts to hedge firm commitments. The
transactions being hedged were net investments in two separate European
subsidiaries. Market value gains and losses on forward contracts hedging firm
commitments will be recognized when the hedged transaction occurs.

                                       6
   9
These contracts, which related primarily to the Euro currency, generally have a
maximum term of two years. Forward exchange contracts receive hedge accounting
on firmly committed transactions when they are designated as a hedge of the
designated currency exposure and are effective in minimizing such exposure.

Forward exchange contracts, that qualify for hedge accounting, with notional
amounts of $9,700,000 and $6,800,000 to exchange Euros for US dollars were
outstanding as of April 1, 2001. For the quarter ended April 1, 2001, the
Company recorded a cumulative unrealized gain of $1,354,000, related to these
foreign exchange contracts, in other comprehensive income. This amount offsets
the foreign exchange impact (the hedged transaction) which resulted in
unrealized foreign exchange losses of $1,182,000 for the quarter ended April 1,
2001.

The market risk exposure from forward exchange contracts is assessed in light
of the underlying currency exposures and is controlled by the initiation of
additional or offsetting foreign currency contracts.

ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     RESULTS OF OPERATIONS

     Revenue for the first quarter of 2001 decreased 19% to $44,206,000 from
     $54,495,000 for the first quarter of 2000. Comparing consecutive quarters,
     revenue decreased 33% from the fourth quarter of 2000. As compared to both
     the first quarter of 2000 and the fourth quarter of 2000, the Company's
     results were negatively impacted by the worldwide slowdown in capital
     equipment spending by manufacturers in the semiconductor and electronics
     industries. Sales to Original Equipment Manufacturers (OEM) customers, most
     of whom make capital equipment used by manufacturers in the these
     industries, decreased $7,593,000, or 23%, from the first quarter of 2000
     and $17,694,000, or 40%, from the fourth quarter of 2000. Sales to end-user
     customers decreased $2,696,000, or 13%, from the first quarter of 2000 and
     $4,184,000, or 19%, from the fourth quarter of 2000, primarily due to lower
     demand from customers who make electronic products.

     The Company anticipates that its results for the second quarter of 2001
     will continue to be negatively impacted by the worldwide slowdown in
     capital equipment spending, primarily in the semiconductor and electronics
     industries. Accordingly, the Company anticipates that its revenue for the
     second quarter of 2001 will be approximately 10% to 15% lower than that
     reported in the first quarter of 2001. The Company has limited visibility
     to customer demand beyond the second quarter of 2001. The Company has
     implemented a number of cost-containment measures, including a restricted
     hiring plan and a reduction in discretionary spending, to more closely
     align expenses to the anticipated lower revenue level.

     Gross profit as a percentage of revenue for the first quarter of 2001 was
     71% compared to 74% and 75% for the first quarter of 2000 and the fourth
     quarter of 2000, respectively. The decrease in the gross margin was due
     primarily to the impact of the lower sales volume and fixed manufacturing
     costs in the first quarter of 2001. The gross margin is expected to
     continue to decrease in the second quarter of 2001 due to the anticipated
     lower revenue for that quarter.

     Research, development, and engineering expenses for the first quarter of
     2001 were $8,182,000 compared to $7,283,000 and $9,710,000 for the first
     quarter of 2000 and the fourth quarter of 2000, respectively. The increase
     of $899,000, or 12%, from the first quarter of 2000 was due primarily to
     higher personnel-related costs to support the Company's continued
     investment in the research and development of new and existing products.
     Included in the higher personnel-related costs are the expenses associated
     with the additional employees from the three acquisitions completed during
     2000. The decrease of $1,528,000, or 16%, from the fourth quarter of 2000
     was due primarily to bonus and recruiting expenses in the fourth quarter of
     2000 that did not recur in the first quarter of 2001, as well as costs
     related to the timing of product development efforts. Expenses as a
     percentage of revenue were 19% for the first quarter of 2001 compared to
     13% and 15% for the first quarter of 2000 and the fourth quarter of 2000,
     respectively. The increase in expenses as a percentage of revenue was a
     result of the lower revenue base in 2001. The Company plans to continue its
     product development efforts, and therefore, anticipates that aggregate
     expenses for the remainder of 2001 will continue at the level experienced
     in the first quarter.

     Selling, general, and administrative expenses for the first quarter of 2001
     were $18,438,000 compared to $12,578,000 and $18,602,000 for the first
     quarter of 2000 and the fourth quarter of 2000, respectively. The increase
     of $5,860,000, or 47%, from the first quarter of 2000 was due primarily to
     higher personnel-related costs to support the Company's expanding worldwide
     operations and grow its end-user business. Included in the higher
     personnel-related costs are the expenses associated with the additional
     employees from the three acquisitions completed during 2000. The decrease
     of $164,000, or 1%, from the fourth quarter of 2000 was due primarily to
     bonus and recruiting expenses in the fourth


                                       8
   11


     quarter of 2000 that did not recur in the first quarter of 2001, as well as
     lower marketing and travel and entertainment costs. Expenses as a
     percentage of revenue were 42% for the first quarter of 2001 compared to
     23% and 28% for the first quarter of 2000 and the fourth quarter of 2000,
     respectively. The increase in expenses as a percentage of revenue was a
     result of the lower revenue base in 2001. The Company expects to realize
     most of the benefits from its cost-containment measures in S,G&A, and
     therefore, anticipates that aggregate expenses for the remainder of 2001
     will be lower than the level experienced in the first quarter.

     Amortization of goodwill for the first quarter of 2001 was $777,000
     compared to $90,000 for the same period in 2000. The increase in
     amortization expense was due to goodwill associated with the three
     acquisitions completed during 2000.

     Investment income for the first quarter of 2001 was $2,718,000 compared to
     $1,821,000 for the same period in 2000, representing a 49% increase. The
     increase in investment income was primarily due to higher average interest
     rates on the Company's portfolio of investments, which consists principally
     of debt securities, as well as a higher average invested cash balance in
     2001.

     The Company's effective tax rate was 32% for both the first quarter of 2001
     and the first quarter of 2000.

     LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash requirements during the first quarter of 2001 were met
     through cash generated from operations. Cash and investments increased
     $7,679,000 from December 31, 2000 primarily as a result of $8,689,000 of
     cash generated from operations, partially offset by $2,397,000 of capital
     expenditures, principally for computer hardware.

     On December 12, 2000, the Company's Board of Directors authorized the
     repurchase of up to $100,000,000 of the Company's common stock. As of April
     1, 2001, the Company had not repurchased any shares under this program.

     The Company believes that its existing cash and investments balance,
     together with cash generated from operations, will be sufficient to meet
     the Company's planned working capital, investing, and financing
     requirements through 2001, including the Company's stock repurchase program
     and potential business acquisitions.

     FORWARD-LOOKING STATEMENTS

     Certain statements made in this report, as well as oral statements made by
     the Company from time to time, which are prefaced with words such as
     "expects," "anticipates," "believes," "projects," "intends," "plans," and
     similar words and other statements of similar sense, are forward-looking
     statements. These statements are based on the Company's current
     expectations and estimates as to prospective events and circumstances,
     which may or may not be in the Company's control and as to which there can
     be no firm assurances given. These forward-looking statements, like any
     other forward-looking statements, involve risks and uncertainties that
     could cause actual results to differ materially from those projected or
     anticipated. Such risks and uncertainties include (1) the loss of, or a
     significant curtailment of purchases by, any one or more principal
     customers; (2) the cyclicality of the semiconductor and electronics
     industries; (3) the Company's continued ability to achieve significant
     international revenue; (4) the capital spending trends by manufacturing
     companies; (5) the inability to protect the Company's proprietary
     technology and intellectual property; (6) the inability to attract or
     retain skilled employees; (7) the technological obsolescence of current

     respond to competitive technology and pricing pressures; and (9) the
     reliance upon certain sole source suppliers to manufacture or deliver
     critical components of the Company's products. The foregoing list should
     not be construed as exhaustive and the Company disclaims any obligation to
     subsequently revise forward-looking statements to reflect events or
     circumstances after the date of such statements or to reflect the
     occurrence of anticipated or unanticipated events. Further discussions of
