              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                       SIX MONTHS ENDED SEPTEMBER 28, 1997


1. The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation S-X. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three and six month periods ended
September 28, 1997 are not necessarily indicative of the results that may be
expected for the year ended March 29, 1998. For further information, refer to
the consolidated financial statements and footnotes thereto included in the
Company's annual report on Form 10-K for the year ended March 30, 1997.

2. The computations of earnings per share are based on the weighted average
number of outstanding shares of common stock and common equivalent shares (using
the treasury stock method). Fully diluted earnings per share have not been
separately presented as the amount does not differ significantly from primary
earnings per share.

In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 128 "Earnings Per Share" which is required to be adopted for the
quarter ending December 28, 1997. At that time, the Company will be required to
change the method currently used to compute earnings per share and to restate
all prior periods. Under the new requirements for calculating primary earnings
per share, the dilutive effect of stock options will be excluded. For the
comparative three and six month periods ending September 28, 1997 and September
29, 1996, earnings (loss) per share pursuant to Statement 128 would have been:

4. On May 23, 1997, the Company acquired 100% of the outstanding stock of
Western Equipment Developments (Holdings) Ltd. ("WED"), located in Plymouth,
England, for approximately $6,000,000 in cash. WED designs, manufactures and
markets integrated circuit wafer handling robot systems used to load, sort and
transport wafers during the inspection stage of the semiconductor manufacturing
process. The acquisition was accounted for as a purchase and accordingly, the
results of operations of the acquired business have been included in the
Company's consolidated financial statements commencing May 23, 1997. In
connection with the acquisition, the Company allocated a portion of the purchase
price to in-process research and development which resulted in a one-time charge
to operations of approximately $4.9 million. The following table summarizes the
unaudited pro-forma consolidated results of operations as if the acquisition had
been made at the beginning of each of the periods presented:

5. In July 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 130 "Reporting Comprehensive Income" which is required to be
adopted in the first quarter of fiscal 1999. The adoption of this standard is
not expected to have a material impact on the Company's financial position or
results of operations.


6. In July 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 131 "Disclosure About Segments of an Enterprise and Related
Information" which is required to be adopted in the first quarter of fiscal
1999. The adoption of this standard is not expected to have a material impact on
the Company's financial position or results of operations.

Item 2.

Management's Discussion and Analysis of Financial Condition and
Results of Operations

Three and six months ended September 28, 1997

Results of Operations
---------------------

Net sales for the second quarter of fiscal 1998 increased 29% to $11.6 million
versus $9 million for the same quarter last year. Net sales for the first six
months of fiscal 1998 increased 2% to $20.4 million compared to $20.0 million
for the first six months of fiscal 1997. The increase in second quarter net
sales resulted primarily from an increase in unit shipments during the second
quarter of fiscal 1998 compared to the second quarter of fiscal 1997.

International sales represented approximately 50% of net sales for the second
quarter of fiscal 1998 versus 44% in the second quarter of fiscal 1997.
Approximately 79% of all international sales were to customers located in the
Pacific Rim region.

Gross margin in the second quarter of fiscal 1998 was 46% compared to 47% in the
same quarter last year. Gross margin for the first six months of fiscal 1998 was
46% compared to 48% in the same period last year. The decline in gross margin
resulted from volume discounts associated with several large quantity orders
shipped during fiscal 1998 and from increased shipments of newer product models
which generally have lower gross margin percentages.

Research and development expenses increased 23% in the second quarter of fiscal
1998 to $1.6 million from $1.3 million in the second quarter of fiscal 1997.
Research and development expenses remained consistent as a percentage of sales
at approximately 14% in both the second quarter of fiscal 1998 and the second
quarter of fiscal 1997. Research and development expenses increased 16% to $2.9
million in the first six months of fiscal 1998 from $2.5 million in the first
six months of fiscal 1997. Increased spending on research and development in the
second quarter of fiscal 1998 was a result of increased spending on the
development of the Company's newest test handler model, the VT8000, and to a
lesser extent, spending associated with the development of Western Equipment
Developments (Holdings) LTD ("WED") newest product a high speed wafer sorter.

Selling, general, and administrative expenses for the second quarter of fiscal
1998 were $3.0 million versus $2.3 million in the second quarter of fiscal 1997.
Selling, general and administrative expenses for the first six months of fiscal
1998 were $5.5 million versus $4.7 million for the first six months of fiscal
1997. Selling, general and administrative expenses also increased as a
percentage of sales to 27% in the first six months of fiscal 1998 from 23% in
the first six months of fiscal 1997. The increase in selling, general and
administrative expenses was due to the  inclusion of a complete quarter of
WED expenses in the second quarter operating results and increased spending in
the second quarter on trade shows and marketing related to the introduction of
the Company's newest test handler and WED's new high speed wafer sorter.

During the first quarter of fiscal 1998, the Company also recorded a one-time
charge to earnings of $4.9 million for acquired in-process research and
development related to the Company's acquisition of WED (See Note 4 to the
Condensed Consolidated Financial Statements included herein).

Operating income in the second quarter of fiscal 1998 was $754,000 versus
operating income of $649,000 in the second quarter of fiscal 1997. Operating
loss in the first six months of fiscal 1998 was $3.9 million versus operating
income of $2.4 million in the first six months of fiscal 1997. The year to date
operating 


                                       8
<PAGE>
 
loss of $3.9 million is attributable to the one-time charge to earnings of $4.9
million recorded in the first quarter of fiscal 1998 relating to the acquired 
in-process research and development associated with the acquisition of WED.

The effective tax rate for the second quarter of fiscal 1998 was 47% versus 33%
for the same quarter last year. The second quarter rate of 47% resulted as the
Company's was not able to offset losses incurred by WED against income earned in
the United States. The Company recorded a tax provision of $595,000 for the
first six months of fiscal 1998 on a pretax loss of $3.7 million. The tax
provision was recorded as a result of the combination of the first quarter
one-time write-off of in-process research and development which is not
deductible for tax purposes and operating losses of WED for which no tax benefit
was recorded.

As a result of the foregoing, net income for the second quarter of fiscal 1998
was $418,000, or $.11 per share, as compared to net income of $538,000, or $.15
per share, for the second quarter of fiscal 1997. Net loss for the first six
months of fiscal 1998 was $4.3 million, or $1.18 per share, as compared to net
income of $1.8 million, or $.49 per share, for the first six months of fiscal
1997

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

The Company ended the second quarter of fiscal 1998 with a cash position of
approximately $6.3 million. The Company has an unsecured line of credit with a
bank in the amount of $5.0 million against which there were borrowings of $2.4
million at the end of the second quarter of fiscal 1998. During the quarter, the
Company elected to utilize its working capital line of credit to cover short
term fluctuations in available cash.

The Company used approximately $2.5 million of cash from operations during the
first six months of fiscal 1998. Accounts receivable increased approximately
$3.3 million during the first six months of fiscal 1998 as a result of both the
increase in sales and the inclusion of WED's accounts receivable balance as a
result of the acquisition. Inventory increased approximately $4.0 million during
the first six months of fiscal 1998 as the result of the Company purchasing
inventory for the production of its first units of a newly introduced test
handler and high speed wafer sorter coupled with the inclusion of WED's
inventory as a result of the acquisition. Accounts payable and accrued expense
increased approximately $5.2 million as a result of both increases in material
receipts and the inclusion of WED's current liabilities in the fiscal 1998
balance sheet.

The Company used approximately $7.4 million in cash for investing activities
during the first six months of fiscal 1998, most of which was used to fund the
Company's acquisition of WED. Additionally, the Company spent approximately
$913,000 on capital equipment purchases and $213,000 to fund internal software
development costs.

The Company generated cash from financing activities in the first six months of
fiscal 1998 of approximately $2.2 million, primarily as the result of utilizing
its working capital line of credit.

The Company believes that funds generated from operations, existing cash
balances and available borrowing capacity will be sufficient to meet the
Company's cash requirements for at least the next twelve months.
