D.  Earnings Per Share


    The Company has adopted Statement of Financial Accounting Standard ("SFAS")
No. 128, "Earnings Per Share," which specifies the computation, presentation and
disclosure requirements for net income (loss) per common share.  Basic net
income (loss) per common share is computed based on the weighted average number
of common shares outstanding during the period.  Diluted net income (loss) per
common share gives effect to all dilutive potential common shares outstanding
during the period.  Under SFAS No. 128, the computation of diluted earnings per
share does not assume the issuance of common shares that have an antidilutive
effect on net income per common share.

</TABLE>

    Options to purchase 15,967 shares of common stock at prices ranging from
$20.13 to $23.88 per share were outstanding at December 29, 1996, but were not
included in the computation of diluted EPS because the option's exercise price
was greater than the average market price of the common shares as of such date
and, therefore, would be antidilutive under the treasury stock method.

E.  Acquisition of Interval Logic Corporation

    On October 29, 1997 the Company acquired Interval Logic Corporation ("ILC"),
a California corporation, for aggregate consideration of 111,258 shares of the
Company's Common Stock. In addition, the Company issued or assumed options to
purchase an aggregate of 199,170 shares of the Company's Common Stock. ILC was
formed in 1995 to develop advanced, high-performance planning and scheduling
software solutions for the semiconductor industry. The value of the transaction
is $8.5 million including approximately $600,000 of expenses related to the
acquisition. The transaction was accounted for as a purchase.

    The purchase price was allocated to the tangible and intangible assets of
ILC based on the fair market value of those assets using a risk adjusted
discounted cash flow approach. Specifically, the purchased technology was
evaluated through extensive interviews and analysis of data concerning the state
of the technology and needed developments. This evaluation of underlying
technology acquired considered the inherent difficulties and uncertainties in
completing the development, and thereby achieving technological feasibility, and
the risks related to the viability of and potential changes in future target
markets. The technology was deemed to be in-process research and development
because the Company needs to make significant further investments in development
of the technology, to integrate it with the Company's products, including the
"Transnet" product line, and to meet expected customer requirements. The
necessary
                                       7
<PAGE>
 
developments include completion of the software requirements definition, data
integration and validation, completion of the graphics user interface,
development of alpha and beta versions for customer testing, and integration and
adaptation with customer systems. The underlying technology had no alternative
future use to the Company in other research and development projects or
otherwise. Therefore, the Company recognized a charge of $8,417,000 for the
purchase of in-process research and development in October 1997.

F.  Provision for Income taxes

    The effective tax rate for the three months ended December 28, 1997, was
adversely affected by the effect of the charge for the acquired in-process
research and development which is not deductable for federal income tax
purposes.  Excluding this charge, the effective tax rate was 33.5% for the three
months ended December 28, 1997, as compared to 34% for the corresponding period
in fiscal year 1997.

G.  Subsequent Events

    On January 22, 1998, the Company completed the acquisition of Equipe
Technologies, Inc. and two related companies (collectively "Equipe"). Equipe is
a leading worldwide developer, manufacturer, and supplier of wafer and substrate
handling robots, pre-aligners and controllers to the semiconductor process tool
manufactures. The acquisition will be accounted for as a pooling-of-interests.
The following pro forma information combines the results of operations of the
Company and Equipe as if the acquisition of Equipe had occurred at the beginning
of the periods presented. Equipe Technologies Inc. and one of the related
companies prior to the acquisition were S-corporations for tax purposes. The pro
forma information gives effect to certain adjustments, including an adjustment
to provide for income taxes as if Equipe Technologies, Inc. and the related
company were treated as C-corporations for the periods presented. The pro forma
information is shown for comparative purposes only.

H.  New Accounting Pronouncements

    In June 1997, the Financial Accounting Standards Board (the "FASB") issued
 Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
 Comprehensive Income." This statement requires that changes in comprehensive
 income be shown in a financial statement that is displayed with the same
 prominence as other financial statements. The statement will be effective for
 annual periods beginning after December 15, 1997 and the Company will adopt its
 provisions in fiscal year 1999. Reclassification for earlier periods is
 required for comparative purposes. The Company is currently evaluating the
 impact this statement will have on its financial statements; however, because
 the statement requires only additional disclosure, the Company does not expect
 the statement to have a material impact on its financial position or results of
 operations.

                                       8
<PAGE>
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." This statement supersedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise." This statement
includes requirements to report selected segment information quarterly and
entity-wide disclosures about products and services, major customers, and the
material countries in which the entity holds assets and reports revenues. The
statement will be effective for annual periods beginning after December 15, 1997
and the Company will adopt its provisions in fiscal year 1999. Reclassification
for earlier periods is required, unless impracticable, for comparative purposes.
The Company is currently evaluating the impact this statement will have on its
financial statements; however, because the statement requires only additional
disclosure, the Company does not expect the statement to have a material impact
on its financial position or results of operations.

    In October 1997, the American Institute of Certified Public Accountants
("AICPA") issued the Statement of Position ("SOP") 97-2 "Software Revenue
Recognition," which will supersede SOP 91-1. SOP 97-2 has not changed the basic
rules of revenue recognition but does provide more guidance particularly with
respect to multiple deliverables and "when and if available" products. SOP 97-2
is effective for transactions entered into for annual periods beginning after
December 15, 1997. The Company will adopt SOP 97-2 in fiscal year 1999 and has
not yet determined its impact.

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

Certain Factors That May Affect Future Results

     From time to time, information provided by the Company, statements made by
its employees or information included in its filings with the Securities and
Exchange Commission may contain statements which are not historical facts but
which are "forward-looking statements" which involve risks and uncertainties. In
particular, statements in "Management's Discussion and Analysis of Financial
Condition and Results of Operations," relating to the Company's revenue and
expense levels, profitability and the sufficiency of capital to meet working
capital and capital expenditures requirements, may be forward-looking
statements. The words "expect," "anticipate," "internal," "plan," "believe,"
"seek," "estimate" and similar expressions also are intended to identify such
forward-looking statements. This Report also contains other forward-looking
statements. Such statements are not guarantees of future performance, and
involve certain risks, uncertainties and assumptions that could cause the
Company's future results to differ materially from those expressed in any
forward-looking statements made by or on behalf of the Company. Many of such
factors are beyond the Company's ability to control or predict. Readers are
accordingly cautioned not to place undue reliance on forward-looking statements.
The Company disclaims any intent or obligation to update publicly any forward-
looking statements whether in response to new information, future events or
otherwise. Important factors that may cause the Company's actual results to
differ from such forward-looking statements include, but are not limited to, the
factors discussed below.

     The Company's future results are subject to substantial risks and
uncertainties. The Company's business and results of operations depend in
significant part upon capital expenditures from manufacturers of semiconductors,
which in turn depend upon the current and anticipated market demand for
semiconductors and products incorporating semiconductors. Historically, the
semiconductor industry has been highly cyclical with recurring periods of over
supply, which often have had a severe effect on the semiconductor industry's
demand for capital expenditures, including systems manufactured and marketed by
the Company. The Company believes that the markets for newer generations of
semiconductors will also be subject to similar fluctuations. Also, the recent
high rate of technical innovation and resulting improvements in the performance
and price of semiconductor devices, which have driven much of the demand for the
Company's products, could slow, or encounter limits, in the future. In addition,
any other factor adversely affecting the semiconductor industry or particular
segments within the semiconductor industry may adversely effect the Company's
business, financial condition and operating results.

     Additional risks and uncertainties include: competitive pressures on
selling prices; inventory management, including suppliers' ability to meet the
Company's needs in a timely manner; the timing and cancellation of customer
orders; changes in product mix; the Company's ability to introduce new products
and technologies on a timely basis; the Company's ability to increase its
manufacturing capacity to meet increased demand while maintaining satisfactory
levels of product quality, service levels, and timeliness of deliveries; rapid
technological change and introduction of products and technologies by the
Company's competitors; market acceptance of the Company's and its competitors'
products; the level of orders received which can be shipped in a quarter, the
timing of investments in engineering and development, the Company's ability to
absorb and manage acquisitions, and risks associated with doing business in Asia
and Europe. The current financial uncertainty within the economies of certain
Asian countries could affect the worldwide semiconductor industry and the
Company. This uncertainty could result in delay or

                                       10
<PAGE>
 
cancellation of orders from customers in these countries. As a result of the
foregoing and other factors, the Company may experience material fluctuations in
future operating results on a quarterly or annual basis which could materially
and adversely affect its business, financial condition, operating results and
stock price.

Results of Operations

     Net Revenue:   Net revenue for the three months ended December 28, 1997 was
$46.8 million, an increase of 25.8% over the corresponding period in fiscal year
1997. The increase resulted primarily from strong domestic demand for the
Company's flexible factory automation systems and customer service and support.
Net export sales to Europe and Asia customers for the three months ended
December 28, 1997 were $16.8 million as compared to $17.4 million for the
corresponding period in fiscal year 1997, and accounted for 35.9% and 46.8% of
net revenue, respectively.

     Gross Profit:  The gross profit margin for the three months ended December
28, 1997 increased to 44.4% as compared to 43.1% for the corresponding period in
fiscal year 1997. The increase is primarily attributable to greater efficiency
in the Company's manufacturing operations associated with higher volumes and
cost reduction efforts undertaken by the Company.

     Research and Development:  Research and development expenses for the three
months ended December 28, 1997 were $6.9 million as compared to $5.6 million for
the corresponding period in fiscal year 1997, representing 14.8% and 15.1% of
net revenue, respectively. The increase in total spending primarily reflects the
increase in personnel and materials expense associated with continuing efforts
in new product development, particularly in 300mm product programs.

     Selling, General and Administrative:  Selling, general and administrative
expenses for the three months ended December 28, 1997 were $6.7 million as
compared to $4.9 million for the corresponding period in fiscal year 1997,
representing 14.3% and 13.1% of net revenue, respectively. The increase in total
spending reflects the Company's continuing investments in sales and support
organization in Europe, Taiwan, and to a lesser extent, Korea.

     Acquired In-Process Research and Development:  In October 1997, the company
acquired Interval Logic Corporation in a transaction valued at $8.5 million,
accounted for as a purchase. Interval Logic Corporation was formed in 1995 to
develop advanced, high-performance planning and scheduling software solutions
for the semiconductor industry. At the time of the acquisition, the purchase
price was allocated to the tangible and intangible assets of ILC based on the
fair market value of those assets using a risk adjusted discounted cash flow
approach. Specifically, the purchased technology was evaluated through extensive
interviews and analysis of data concerning the state of the technology and
needed developments. This evaluation of underlying technology acquired
considered the inherent difficulties and uncertainties in completing the
development, and thereby achieving technological feasibility, and the risks
related to the viability of and potential changes in future target markets. The
technology was deemed to be in-process research and development because the
Company needs to make significant further investments in development of the
technology, to integrate it with the Company's products, including the
"Transnet" product line, and to meet expected customer requirements. The
necessary developments include completion of the software requirements
definition, data integration and validation, completion of the graphics user
interface, development of alpha and beta versions for customer testing, and
integration and adaptation with customer systems. The underlying technology had
no alternative future use to the Company in other research and development

                                       11
<PAGE>
 
projects or otherwise. Therefore, the Company recognized a charge of $8,417,000
for the purchase of in-process research and development in October 1997.

     Operating (Loss) Profit:  The loss from operations for the three months
ended December 28, 1997 was $1.3 million as compared to income from operations
of $5.5 million for the corresponding period in fiscal 1997. Excluding the non-
recurring charge of $8.4 million related to acquired in-process research and
development recorded in the connection with the acquisition of Interval Logic
Corporation, operating income for the three months ended December 28, 1997 would
have been $7.2 million and operating margins would have increased to 15.3% from
14.9% in the comparable period in fiscal 1997.

     Other Income, Net:  Other income, net for the three months ended December
28, 1997 was $312,000 as compared to $347,000 for the corresponding period in
fiscal year 1997. Interest income for the three months ended December 28, 1997
was $325,000 as compared to $346,000 for the corresponding period in fiscal year
1997. The decrease is attributable to lower average cash and investment
balances.

     Income Tax Provision:  The effective tax rate for the three months ended
December 28, 1997 was adversely affected by the effect of the charge for the
acquired in-process research and development which is not deductible for federal
income tax purposes. Excluding this charge, the effective tax rate was 33.5% for
the three months ended December 28, 1997, as compared to 34.0% for the
corresponding period in fiscal year 1997.

     Net (Loss) Income: The net loss for the three months ended December 28,
1997 was $3.4 million compared to net income of $3.9 million for the
corresponding period in fiscal year 1997. Excluding the charge for acquired in-
process research and development, net income for the three months ended December
28, 1997 would have been $5.0 million, or 10.6% of net revenue, as compared to
$3.9 million, or 10.4% of net revenue, in the same period in fiscal year 1997.
Diluted net income per common share excluding the charge for acquired in-process
research and development would have been $0.31 for the three months ending
December 28, 1997 as compared to $0.25 for the corresponding period in fiscal
year 1997.

     Since its inception, the Company has funded its operations primarily
through private equity financings, bank lines of credit, public stock offerings
in October 1994 and July 1995 and cash generated from operations.

     As of December 28, 1997 the Company had working capital of $109.3 million,
including cash and cash equivalents of $39.8 million and short-term marketable
securities of $3.1 million.

     Net cash provided by operating activities for the three months ended
December 28, 1997 was $12.7 million, compared to net cash used in operating
activities of $10.8 million for the corresponding period in fiscal year 1997.
Net cash provided by operating activities for the three months ended December
28, 1997 was primarily attributable to net income prior to the non-cash charge
associated with acquired in-process research and development of $5.0 million and
decreases in trade accounts receivable of $13.9 million, and inventory of $2.7
million, offset partially by an increase in contracts in process of $4.1 million
and decreases in accounts payable of $1.7 million and in accrued expenses of
$3.2 million. Net cash used in operating activities for the three months ended
December 29, 1996 was primarily attributable to increases in trade

                                       12
<PAGE>
 
accounts receivable of $6.4 million, contracts in progress of $5.5 million and
in inventory of $3.3 million, which more than offset net income of $3.9 million.

     Net cash used in investing activities for the three months ended December
28, 1997 was $2.3 million as compared to net cash provided by investing
activities of $4.5 million for the corresponding period in fiscal year 1997. Net
cash used in investing activities for the three months ended December 28, 1997
was attributable to purchases of property and equipment of $1.8 million and of
marketable securities of $1.1 million offset partially by proceeds from
maturities of marketable securities of $685,000. Net cash provided by investing
activities for the three months ended December 29, 1996 was attributable to net
proceeds from sales of marketable securities of $6.0 million and proceeds from
maturities of marketable securities of $2.9 million offset partially by the
purchases of marketable securities of $3.2 million and property and equipment of
$1.1 million.

     Net cash provided by financing activities for the three months ended
December 28, 1997 was $231,000 as compared to $707,000 for the corresponding
period in fiscal year 1997, and was attributable to the exercise of stock
options and issuance of common stock pursuant to the Company's Employee Stock
Purchase Plan.

     At December 28, 1997, the Company had no borrowings under its working
capital line of credit from Fleet Bank of Massachusetts, N.A. (the "Bank"). The
working capital line of credit enables the Company to obtain revolving loans or
grant letters of credit on an unsecured basis up to the lesser of 80% of
eligible accounts receivable or $10,000,000, with outstanding borrowings under
revolving loans bearing interest at the Bank's prime lending rate. The ability
of the Company to effect borrowings under the line of credit is conditioned
upon, among other things, the Company's meeting certain financial covenants,
including covenants requiring the maintenance of specific levels of quarterly
and annual earnings, working capital, tangible net worth, debt service coverage
and liquidity. The Company may elect to convert revolving loans into loans
bearing interest at 1.5% above the Bank's cost of funds. The working capital
line of credit expires on March 1, 1998. The Company believes that existing cash
and investment balances and funds available under its existing line of credit
will be sufficient to meet the Company's cash requirements to fund operations
and expected capital expenditures during the next twelve months.

Acquisition of Equipe Technologies

     On January 22, 1998, the Company completed the acquisition of Equipe
Technologies, Inc. and two related companies (collectively, "Equipe"). Equipe is
a leading worldwide developer, manufacturer, and supplier of wafer and substrate
handling robots, pre-aligners and controllers to the semiconductor process tool
manufacturers. The acquisition will be accounted for as a pooling-of interests.
The company believes the acquisition strengthens its position in semiconductor
factory automation and extends its ability to deliver complete wafer-flow
solutions allowing it to automate virtually every wafer move throughout the fab.

New Accounting Pronouncements

     In June 1997, the Financial Accounting Standards Board (the "FASB") issued
 Statement of Financial Accounting Standards (the "SFAS") No. 130, "Reporting
 Comprehensive Income." This statement requires that changes in comprehensive
 income be shown in a financial statement that is displayed with the same
 prominence as other financial statements. The statement will be effective for
 annual periods beginning after December 15, 1997 and the Company will adopt its
 provisions in fiscal year 1999. Reclassification for earlier periods is
 required for comparative

                                       13
<PAGE>
 
purposes. The Company is currently evaluating the impact this statement will
have on its financial statements; however, because the statement requires only
additional disclosure, the Company does not expect the statement to have a
material impact on its financial position or results of operations.

     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." This statement supersedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise." This statement
includes requirements to report selected segment information quarterly and
entity-wide disclosures about products and services, major customers, and the
material countries in which the entity holds assets and reports revenues. The
statement will be effective for annual periods beginning after December 15, 1997
and the Company will adopt its provisions in fiscal year 1999. Reclassification
for earlier periods is required, unless impracticable, for comparative purposes.
The Company is currently evaluating the impact this statement will have on its
financial statements; however, because the statement requires only additional
disclosure, the Company does not expect the statement to have a material impact
on its financial position or results of operations.

     In October 1997, the American Institute of Certified Public Accountants
("AICPA") issued the Statement of Position ("SOP") 97-2 "Software Revenue
Recognition," which will supersede SOP 91-1. SOP 97-2 has not changed the basic
rules of revenue recognition but does provide more guidance particularly with
respect to multiple deliverables and "when and if available" products. SOP 97-2
is effective for transactions entered into for annual periods beginning after
December 15, 1997. The Company will adopt SOP 97-2 in fiscal year 1999 and has
not yet determined its impact.
