PROSPECTUS SUMMARY
The following summary is qualified in its entirety by the more detailed
information and the financial statements and notes thereto appearing elsewhere
in this Prospectus.
THE COMPANY
ADE Corporation is a leader in the design, manufacture, marketing and service
of metrology and inspection systems for the semiconductor wafer manufacturing
industry. The Company is also a growing supplier of metrology systems to the
semiconductor device and computer hard disk industries. The Company's systems
analyze and report product quality at critical manufacturing process steps,
sort wafers and disks and provide manufacturers with quality certification
data. Semiconductor wafer and device and computer hard disk manufacturers use
the Company's systems to improve yield and capital productivity. The Company's
products have evolved from single instruments used in off-line engineering
analysis to multi-function systems for automated in-line monitoring of process-
induced defects throughout the wafer and disk manufacturing processes. The
Company's systems are designed to deliver the high throughput, reliability and
information delivery and analysis necessary to meet the demands of increasingly
complex and time-sensitive manufacturing processes. The Company has over 35
major products currently in use by the semiconductor wafer and device and hard
disk manufacturing industries and has shipped more than 1,700 systems.
As the performance of semiconductors has increased and their size and cost
have decreased, the demand for semiconductors has expanded beyond the primary
market in computer systems to include applications in telecommunications,
automotive products, consumer goods and industrial automation and control. New
geographic markets for semiconductors have also emerged, particularly in the
Pacific Rim. VLSI Research Inc., an independent semiconductor industry research
organization, estimates that the semiconductor market will be $155 billion in
1997 and will grow to $356 billion in the year 2002. Peripherals Research, an
independent computer disk industry research organization, estimates that in the
hard disk market demand will be 411 million disks in 1997 and will exceed 639
million disks in the year 1999. To meet this expected strong growth, wafer,
device and disk manufacturers are currently making significant investments in
capital equipment for new facilities and the expansion of capacity at existing
facilities.
Semiconductor devices are becoming more complex, requiring finer line widths
and more sophisticated manufacturing processes. Key factors in improving the
yields of these processes are the flatness of wafers and the absence of
particles on the surface of the wafers. Wafer manufacturers use the Company's
equipment to measure and identify flatness, shape, resistivity, conductivity
type, particles and other surface defects. The measurement information derived
from the Company's metrology and inspection systems enables wafer manufacturers
to control their processes continuously. Device manufacturers currently use the
Company's metrology products to perform incoming quality control and various
other significant measurement functions. Key opportunities for the Company
include the growing demand for epitaxial ("Epi") wafers and the increasing use
of chemical mechanical planarization ("CMP"), an advanced wafer flattening
procedure, as well as yield management software solutions in the wafer and
device industries.
The recent introduction of highly sensitive Magneto-Resistive ("MR")
recording head technology has significantly increased the potential data
capacity of hard disks and has placed rigorous new demands on magnetic data
storage disk specifications. Manufacturers of hard disks use the Company's
automated in-line equipment to measure taper and thickness. In addition,
through its acquisition of Digital Measurement Systems, Inc. ("DMS") in
February 1997, the Company has broadened its product line of metrology
4
<PAGE>
solutions for hard disk manufacturers to include automated in-line equipment
that measures the magnetic properties of the disk recording surfaces. The
Company believes these products are the only commercially available automated
high speed in-line magnetic properties measurement tools available to the disk
manufacturing industry. The measurement information derived from the Company's
metrology systems enables hard disk manufacturers to continuously monitor and
control their processes and to improve yields.
ADE's strategy is to build on its leading technological and market position
in providing metrology and inspection systems to wafer manufacturers and to
increase its penetration in the device fabrication and hard disk industries.
The Company also plans to increase the number and type of metrology and
inspection functions that its products perform, in part by continuing to
automate functions currently performed by human inspectors. The Company is
committed to providing software solutions which increase its customers' yield
management and capital productivity. In addition, the Company plans to continue
developing information management software tools to integrate further its
systems with its customers' management information systems. ADE expects to be
able to deliver benefits to the semiconductor device and hard disk industries
by leveraging its measurement and automation technology and worldwide sales and
service organizations.
ADE markets and sells its products through a direct sales force in the United
States, Europe and Malaysia, through distributors in Japan and through third
party representatives in the remainder of Asia. The Company's customers include
all of the leading semiconductor wafer manufacturers such as SEH, MEMC, Wacker,
Siltec and Sumitomo Sitix and many of the world's semiconductor device
manufacturers such as IBM, Intel, Lucent Technologies, Motorola and Texas
Instruments, as well as many of the leading manufacturers of hard disks and
disk drives, including HMT, IBM, Komag, Seagate Technology and Western Digital.
The Company was incorporated in Massachusetts in 1967. The Company's
principal executive offices and manufacturing facility are located at 80 Wilson
Way, Westwood, Massachusetts 02090, and its telephone number is (617) 467-3500.

RISK FACTORS
In addition to the other information included in this Prospectus, the
following risk factors should be considered carefully in evaluating an
investment in the shares of Common Stock offered by this Prospectus. Certain
statements in this Prospectus are forward-looking statements within the
meaning of Section 27A of the Securities Act and Section 21E of the Exchange
Act. Such forward-looking statements may be found in the material set forth
under the headings, "Prospectus Summary," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business," as
well as elsewhere in this Prospectus, including the documents incorporated by
reference herein. The Company's actual results could differ materially from
those anticipated in such forward-looking statements as a result of certain
factors, including those discussed below and elsewhere in this Prospectus and
in the documents incorporated by reference herein. Any forward-looking
statements are made as of the date of this Prospectus and the Company assumes
no obligation to update any such forward-looking statements or to update the
reasons why actual results could differ materially from those anticipated in
such forward-looking statements.
Cyclicality of the Company's Business. The Company's business depends in
large part upon the capital expenditures of semiconductor wafer and device and
computer hard disk and disk drive manufacturers, which in turn depend on the
current and anticipated market demand for integrated circuits, products
utilizing integrated circuits and systems requiring hard disk drives,
respectively. The semiconductor and hard disk industries are cyclical and have
historically experienced periodic downturns, which have had a severe effect on
the demand for capital equipment. Two of the principal companies in the disk
drive industry have recently announced less than expected demand for their
disk drive products. Prior semiconductor and hard disk industry downturns and
construction of excess capacity by the industry have adversely affected the
Company's revenues, gross margin and net income and have also adversely
affected the market price for the Company's Common Stock. No assurance can be
given that the Company will continue to achieve the revenue growth it has
experienced in recent years. In addition, the need for continued investment in
research and development and extensive customer service and support capability
worldwide will limit the Company's ability to reduce expenses in the event of
a downturn in the industry.
Fluctuations of Quarterly Operating Results. The Company's quarterly
operating results have varied and may continue to vary significantly. The
Company's quarterly revenues typically are derived from a relatively small
number of customer orders. These customer orders often consist of multiple
systems, each of which are priced between approximately $100,000 and $750,000.
As a result, the timing of significant orders or a reduction in the number of
systems shipped in a quarter could have a material effect on the Company's
revenues and results of operations for that quarter. The results for a
particular quarter may also vary due to a number of factors, including
economic conditions in the semiconductor and hard disk industries, the timing
of shipments of orders to major customers, the mix of products sold by the
Company, competitive pricing pressures and the Company's ability to design,
introduce and manufacture new products on a cost effective and timely basis.
Moreover, customers may cancel or reschedule shipments, and production
difficulties or the inability to obtain critical components could delay
shipments. In addition, the Company's product sales have fluctuated, and are
likely to continue to fluctuate, based on seasonal factors, such as customers'
capital budget approval cycles, among others. These factors could have a
material adverse effect on the Company's results of operations. The Company
has increased its research and development spending in recent periods, in part
to support its development of systems for next-generation 300 millimeter
semiconductor wafers. The Company's expense levels are fixed in advance and
based in part on its expectations as to future revenues. As a consequence, any
material shortfall in revenue in a given quarter could have a material adverse
effect on the Company's earnings.
Rapid Technological Change and Introduction of New Products. The market for
semiconductor wafer and device and computer hard disk metrology and inspection
equipment is characterized by rapid
7
<PAGE>
technological advances, changing customer requirements, evolving industry
standards and frequent new product introductions and enhancements. The
Company's future success will depend in large part on the Company's ability to
enhance its current products and to develop and introduce new products that
keep pace with technological developments, achieve market acceptance and
respond to customer requirements that are constantly evolving. New product
introductions may contribute to fluctuations in quarterly operating results,
as customers may defer ordering products from the Company's existing product
lines. If new products have reliability or quality problems, then reduced
orders, higher manufacturing costs, delays in collecting accounts receivable
and additional service and warranty expense may result. Responding to rapid
technological change and the need to develop and introduce new products to
meet customers' expanding needs and evolving industry standards will require
the Company to make substantial investments in research and product
development. Any failure by the Company to anticipate or respond adequately to
technological developments and customer requirements or any significant delays
in product development or introduction could result in a loss of
competitiveness and could materially adversely affect the Company's operating
results. There can be no assurance that the Company will successfully develop
and manufacture new products or that any product enhancements or new products
developed by the Company will gain market acceptance. The semiconductor wafer
industry is currently undergoing a gradual evolution from 200 millimeter to
300 millimeter wafers. Wafer manufacturers are beginning to establish pilot
production lines and specifications for the manufacture of 300 millimeter
wafers. The Company is currently developing product enhancements and new
products designed to meet increasing demand for metrology and inspection
equipment for 300 millimeter wafers. One of the Company's competitors recently
began shipping an optical inspection product for 300 millimeter wafers. Until
the Company begins shipping its next generation product, the Company's sales
of its wafer inspection systems could be adversely affected. There can be no
assurance that the Company will be able to develop enhancements and new
products successfully or in time to meet emerging demand, or that enhancements
and new products developed by the Company will be accepted by the Company's
customers.
Competition. The semiconductor and computer hard disk equipment industries
are highly competitive. There can be no assurance that companies with
complementary technologies and greater financial resources will not enter
these industries and develop products that are superior to the Company's
products or achieve market acceptance. In the market for optical defect
inspection equipment, the Company competes directly with Hitachi Electronics
Engineering Co., Ltd. and KLA-Tencor Corporation, both of which have
significantly greater financial resources than the Company. In the metrology
area of the device industry, the Company has encountered, and expects to
encounter in the future, competition from companies offering similar and
competing technologies, some of which have significantly greater financial
resources than the Company or an existing market presence in the device
industry, or both. The Company also expects to encounter intense competition
in the areas of metrology and inspection for the hard disk industry. The
Company's competitors can be expected to continue to improve the design and
performance of their products and to introduce new products with competitive
price/performance characteristics. Competitive pressures often necessitate
price reduction which can adversely affect operating results. In order to
remain competitive, the Company must maintain a high level of investment in
research and development and sales, marketing and service. There can be no
assurance that the Company will have sufficient resources to continue to make
such investment or that the Company will be able to make the technological
advances necessary to remain competitive. Currently, the Company's lead times
for the delivery of products to its customers are longer than the industry
average, and, as a consequence, the Company has in a limited number of cases
failed to obtain customer orders. Although the Company is taking steps to
reduce lead times, there can be no assurance that the Company will be
successful in sufficiently reducing its lead times. The failure to
sufficiently reduce lead times may result in lost business in the future and
may have an adverse impact on the Company's business and results of
operations.
KLA Corporation recently acquired a competitor of the Company in the market
for optical defect inspection equipment, Tencor Corporation, to form KLA-
Tencor Corporation. The Company expects that similar acquisitions and business
combinations by competitors and potential competitors of the Company,
8
<PAGE>
in the metrology as well as in the defect inspection markets, may continue in
the future. Acquisitions by the Company's competitors and potential
competitors could allow them to offer new products without the lengthy time
delays typically associated with internal product development, which could
afford such competitors and potential competitors an advantage in meeting
customers' demands. Such acquisitions by others could also have the effect of
limiting the Company's access to commercially significant technologies. The
greater resources, including financial and marketing and support resources, of
competitors engaged in these acquisitions could permit them to accelerate the
development and commercialization of new competitive products and the
marketing of existing competitive products to their larger installed bases.
Accordingly, such business combinations and acquisitions by competitors and
potential competitors could have an adverse impact on both the Company's
market share and the pricing of its products, which could have a material
adverse effect on the Company's business and results of operations.
The Company relies upon a combination of internal product development and
partnerships with certain other companies to broaden its product line to meet
customer demand. The increasing competitiveness within the industry, together
with acquisitions by the Company and its competitors of businesses possessing
complementary technologies, could materially limit the Company's ability to
continue to partner with other companies for new or complementary products,
which could have a material adverse effect upon the Company's ability to offer
in a timely manner products that meet customers' needs.
Management of Growth. The Company has been experiencing a period of
significant growth that could place a strain on its management and other
resources. To support the Company's growth, the Company will need to hire more
engineering, manufacturing, sales and marketing, and support and
administrative personnel, expand customer service capabilities, and update or
expand management information systems, procedures and controls. Competition
for the necessary personnel in the Company's industries is high. There can be
no assurance that the Company will be able to attract and retain the necessary
personnel to accomplish its growth strategies or that it will be able to
satisfy customer demand in a timely fashion and satisfactorily support its
customers and operations or that its information systems, procedures and
controls will be adequate to support the Company's operations. If the
Company's management is unable to manage growth effectively, the Company's
business, operating results and financial condition could be materially
adversely affected.
Customer and Industry Concentration. A relatively limited number of
customers have historically accounted for a substantial portion of the
Company's revenues in each year. In fiscal years 1995, 1996 and 1997, sales to
the Company's top five customers in each period, all of which are in the
semiconductor wafer industry, accounted for approximately 51%, 45% and 50%,
respectively, of the Company's revenue. In fiscal 1997, one of the Company's
customers accounted for 16% of the Company's revenue. The loss of or any
reduction in orders by any of these customers, including reductions due to
market, economic or competitive conditions in the semiconductor industry or in
other industries that manufacture products utilizing semiconductors, could
adversely affect the Company's business, financial condition and results of
operations. In each of the last three fiscal years the Company has derived
over 70% of its revenue, including approximately 77% in fiscal 1997, from
customers in the semiconductor wafer industry. While the Company is focusing
on expanding the level of its business in the device and hard disk industries,
there can be no assurance that the Company's efforts will be successful. The
Company's ability to maintain or increase its sales levels in the future will
depend in part upon its ability to obtain orders from new customers as well as
the financial condition and success of its existing customers and the general
economy. There can be no assurance that the Company will be able to maintain
or continue to increase the level of its revenues in the future or that the
Company will be able to retain existing customers or to attract new customers.
In addition, given the limited number of customers, any delay in collecting,
or inability to collect, accounts receivable could have a material adverse
effect on the Company's financial results. See Note 11 of Notes to
Consolidated Financial Statements.
9
<PAGE>
Dependence on Suppliers. Certain of the components and subassemblies,
including certain systems controllers and robotics components, incorporated in
the Company's systems are obtained from a single source or a limited group of
suppliers. The Company has not qualified a second source for these products
and the partial or complete loss of certain of these sources could have an
adverse effect on the Company's results of operations and damage customer
relationships. Further, a significant increase in the price of one or more of
these components could adversely affect the Company's results of operations.
Risks Associated with International Operations. International sales
accounted for 53%, 59% and 60% of the Company's revenues for the fiscal years
1995, 1996 and 1997, respectively. See Note 11 of Notes to Consolidated
Financial Statements. The Company expects that international sales will
continue to represent a significant percentage of revenues. The Company's
international business may be affected by changes in demand resulting from
fluctuations in interest and currency exchange rates as well as by factors
such as the risk of government financed competition, changes in trade
policies, tariff regulations and difficulties in obtaining U.S. export
licenses.
Patents and Other Intellectual Property. The Company's success depends in
part on its proprietary technology. The Company attempts to protect its
proprietary technology through patents, copyrights, trademarks, trade secrets
and license agreements. The Company believes, however, that its success will
depend to a greater extent upon innovation, technological expertise and
distribution strength. There can be no assurance that the Company will be able
to protect its technology or that competitors will not be able to develop
similar technology independently. No assurance can be given that the claims
allowed on any patents held by the Company will be sufficiently broad to
protect the Company's technology. In addition, no assurance can be given that
any patents issued to the Company will not be challenged, invalidated or
circumvented or that the rights granted thereunder will provide competitive
advantages to the Company. In addition, effective patent, copyright and trade
secret protection may be unavailable or limited in certain foreign countries.
As is typical in the Company's industry, the Company and its customers from
time to time receive letters from third parties, including some of the
Company's competitors, alleging infringement of such parties' patent rights by
the Company's products. There can be no assurance that the Company would
prevail in any litigation seeking damages or expenses from the Company or to
enjoin the Company from selling its products on the basis of such alleged
infringement or that the Company would be able to license any infringed
patents on reasonable terms.
Some customers using certain products of the Company have received a notice
of infringement from Technivision Corporation and Jerome H. Lemelson, alleging
that equipment used in the manufacture of semiconductor products infringes
patents issued to Mr. Lemelson relating to "computer image analysis" or
"digital signal generation and analysis." Certain of these customers have
notified the Company that they may seek indemnification from the Company for
any damages and expenses resulting from this matter. Neither the Company nor
any of its products has been identified by Mr. Lemelson as infringing his
patents. There can be no assurance, however, that Mr. Lemelson would not bring
a claim against the Company for infringement or that the Company would prevail
in any such action. If Mr. Lemelson were to prevail in any such action, the
Company might be required to pay license fees or royalties to Mr. Lemelson,
which could have an adverse impact on the Company's profitability.
Risks Associated with Acquisitions and Alliances. The Company has addressed
the need to offer new products, in part, through the acquisition of technology
and other businesses. The acquisition of other businesses involves numerous
risks, including the difficulty of assimilating the operations, technologies
and products of the acquired business, the diversion of management's attention
from other business concerns, the risks of entering markets in which the
Company has no or limited direct prior experience and must compete with
competitors having stronger market positions, the potential loss of key
employees of the acquired business and the risk that any such acquisitions
could reduce the Company's future earnings. The integration of other
businesses into ADE requires, among other things, integration of
10
<PAGE>
product offerings and coordination of sales, marketing, research, development,
and management organizations. There can be no assurance that such integration
will be accomplished smoothly or successfully. The difficulties of such
integration may be increased by the necessity of coordinating organizations
which are separated geographically. The inability of management to
successfully integrate the operations of such acquired businesses could have a
material adverse effect on the business and results of operations of the
Company.
Control By Existing Stockholders. The Company's directors and executive
officers and members of their immediate families will beneficially own
approximately 34% of the Company's outstanding shares of Common Stock upon
completion of this offering. Accordingly, these stockholders acting together
will have the ability to significantly influence corporate actions requiring
stockholder approval, including the election of the Company's directors. This
concentration of ownership may also have the effect of delaying or preventing
a change of control of the Company. See "Management" and "Principal and
Selling Stockholders."
Volatility of Stock Price. The stock market in general and the market for
shares of technology companies in particular recently have experienced extreme
price fluctuations, which have often been unrelated to the operating
performance of the affected companies. Many companies in the semiconductor and
semiconductor equipment industries, including the Company, experienced
dramatic volatility in the market prices of their common stock during the last
two years. The Company believes that factors such as announcements of
developments related to the Company's business or its competitors' or
customers' businesses, fluctuations in the Company's financial results,
general conditions or developments in the semiconductor and semiconductor
equipment industries and the worldwide economy, sales of the Company's Common
Stock into the market, the number of market makers for the Company's Common
Stock, announcements of technological innovations or new or enhanced products
by the Company or its competitors or customers, a shortfall in revenue, gross
margin, earnings or other financial results from or changes in analysts'
expectations and developments in the Company's relationships with its
customers and suppliers, or a variety of factors beyond the Company's control
could cause the price of the Company's Common Stock to fluctuate, perhaps
substantially. There can be no assurance that the market price of the
Company's Common Stock will not experience significant fluctuations in the
future, including fluctuations that are material, adverse and unrelated to the
Company's performance.

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion provides an analysis of the Company's financial
condition and results of operations and should be read in conjunction with the
"Selected Consolidated Financial Data" and the Consolidated Financial
Statements and Notes thereto included elsewhere in this Prospectus.
OVERVIEW
The Company was founded in 1967 to develop and market certain advanced
concepts and designs in capacitive and other measurement technologies suitable
for industrial applications requiring precise, reliable, damage-free and
repeatable measurements. The Company's products have evolved from single
instruments used in off-line engineering analysis to multi-function systems
for automated in-line monitoring of process-induced defects throughout the
wafer and disk manufacturing processes. The Company operates in two major
business areas, the Semiconductor Group and the Computer Disk Group. The
Semiconductor Group manufactures multifunctional semiconductor metrology and
automation systems and optical wafer defect inspection equipment used to
detect particles and other defects on wafer surfaces. The Computer Disk Group
is primarily engaged in the production of metrology systems for the computer
hard disk industry.
A relatively limited number of customers have accounted for a substantial
portion of the Company's revenue. Moreover, during the past fiscal year
approximately 77% of the Company's revenue was derived from sales made to
wafer manufacturers, with the remainder of the revenue derived principally
from sales to manufacturers of semiconductor devices and computer hard disks.
The Company derives a substantial portion of its revenue from a relatively
small number of customer orders. These customer orders often consist of
multiple systems, which can range in price from approximately $100,000 to
$750,000. As a result, the timing of significant orders or a reduction in the
number of systems shipped in a quarter could have a material effect on the
Company's revenue and results of operations for that quarter.
The Company records revenue from product sales upon shipment to the
customer. The Company accrues for warranty costs upon shipment and recognizes
service revenue when the service is performed. Revenue under certain long-term
contracts containing custom engineering is recognized under the percentage of
completion method.
In February 1997, the Company acquired all of the outstanding stock of and a
building used by Digital Measurement Systems, Inc. ("DMS") of Burlington,
Massachusetts. DMS provides magnetic measurement equipment and systems to the
computer hard disk manufacturing industry. This transaction has been accounted
for as a pooling-of-interests and, therefore, the accompanying financial
information has been retroactively restated to reflect the financial position
and results of operations and cash flows of the Company and DMS for all
periods presented.
RESULTS OF OPERATIONS
For the periods indicated, the following table sets forth the percentage of
total revenue represented by the respective line items in the Company's
consolidated statement of income.

</TABLE>

<PAGE>
Fiscal Year Ended April 30, 1997 Compared to Fiscal Year Ended April 30, 1996
Revenue. Revenue increased 50.6% to $101.4 million in fiscal 1997 from $67.3
million in fiscal 1996. The increase was primarily due to increased unit sales
of the Company's products. The increase in unit sales resulted primarily from
strong demand for capital equipment in the semiconductor industry and
increased demand for gaging equipment in the computer disk drive industry. In
fiscal 1997, $6.3 million of revenue was provided by the operations of DMS
versus $1.7 million in fiscal 1996. The Company is currently developing
product enhancements and new products designed to meet increasing demand for
metrology and inspection equipment for 300 millimeter wafers. A competitor of
the Company has recently begun shipping an optical inspection product for 300
millimeter wafers. The Company believes that its next generation product,
which has not yet been shipped to customers, will be technologically superior
to the competitor's new product. Until the Company begins shipping its next
generation product, the Company's sales of its wafer inspection systems could
be adversely affected.
Gross Margin. Gross margin increased to 55.8% in fiscal 1997 from 53.8% in
fiscal 1996. The increase was primarily due to distributing relatively fixed
overhead costs over increased sales. Gross margins were higher in the first
and second quarters of fiscal 1997, as the Company operated near capacity in
its facilities, as compared to the third and fourth quarters of fiscal 1997.
During the third and fourth quarters of the fiscal year, the Company increased
capacity and overhead by moving into a new facility in Westwood, Massachusetts
and by increasing the capacity of its existing facility in Charlotte, North
Carolina. Gross margins in the immediate future are expected to be consistent
with the margins experienced during the third and fourth quarters of fiscal
1997.
Research and Development. Research and development expense in fiscal 1997
increased 118.2% to $17.0 million from $7.8 million in fiscal 1996 and
increased as a percent of revenue to 16.8% from 11.6%. This increase was
primarily due to increased spending on next generation products and expenses
recognized during the fourth quarter for products under development, a portion
of which had been capitalized during the previous three quarters. While future
research and development expenses are expected to increase over previous
quarters as the Company continues development of next generation products, the
Company expects that expenses as a percent of revenue should return to levels
experienced during the first three quarters of fiscal 1997.
Marketing and Sales. Marketing and sales expense increased 34.4% to $13.7
million in fiscal 1997 from $10.2 million in fiscal 1996, but decreased as a
percentage of revenue to 13.5% in fiscal 1997 from 15.1% in fiscal 1996.
General and Administrative. General and administrative expenses increased
10.2% to $7.4 million in fiscal 1997 from $6.8 million in fiscal 1996 and
decreased as a percent of revenue to 7.3% from 10.0%. General and
administrative expenses increased at a lower rate than revenue growth, as
these expenses are relatively stable compared to revenue growth.
Other Income (Expense). Net interest income was $329,000 in fiscal 1997
versus net interest income of $331,000 in fiscal 1996. Interest income was
offset by interest expense associated with an Industrial Development Bond used
to finance the acquisition and renovation of the Westwood manufacturing
facility.
Provision for Income Taxes. The effective tax rates for fiscal 1997 and 1996
were 30.4% and 33.9%, respectively, and differed from the federal statutory
rate primarily because of benefits from the use of a foreign sales corporation
by the Company and state income taxes. The fiscal 1997 rate was lower than the
fiscal 1996 rate due to the benefit of investment tax credits resulting from
increased capital spending in fiscal 1997 and the benefit from federal and
state research and development tax credits realized in the fourth quarter of
fiscal 1997.
16
<PAGE>
Fiscal Year Ended April 30, 1996 Compared to Fiscal Year Ended April 30, 1995
Revenue. Revenue increased 45.9% to $67.3 million in fiscal 1996 from $46.2
million in fiscal 1995. The increase was due to increased unit sales of the
Company's products and a price increase announced in January 1995. The
increase in unit sales resulted primarily from strong demand for capital
equipment in the semiconductor industry and increased demand for gaging
equipment in the computer disk drive industry.
Gross Margin. Gross margin increased to 53.8% in fiscal 1996 from 49.5% in
fiscal 1995. The increase was primarily due to distributing relatively fixed
overhead costs over increased sales and a price increase announced in January
1995, the impact of which occurred during fiscal 1996.
Research and Development. Research and development expense in fiscal 1996
increased 23.4% to $7.8 million from $6.3 million in fiscal 1995, but
decreased as a percentage of revenue to 11.6% in fiscal 1996 from 13.7% in
fiscal 1995, as revenue increased at a rate greater than the increase in
research and development expense. Total expense for research and development
increased as the Company made significant investments in next generation
products.
Marketing and Sales. Marketing and sales expense increased 48.6% to $10.2
million in fiscal 1996 from $6.8 million in fiscal 1995, and increased as a
percentage of revenue to 15.1% in fiscal 1996 from 14.8% in fiscal 1995. This
increase in expenditures was due to additions in staffing required to support
increased demand for the Company's products.
General and Administrative. General and administrative expenses increased
51.7% to $6.8 million in fiscal 1996 from $4.5 million in fiscal 1995. The
increase was due to higher bonus expenses associated with improved
performance, higher employee benefit costs, increased legal fees associated
with various legal matters and additional expenses associated with being a
public company.
Other Income (Expense). Net interest income was $331,000 in fiscal 1996
versus net interest expense of $404,000 in fiscal 1995. The increase in income
resulted from interest earned on the proceeds of the initial public offering
of the Company's Common Stock completed in October 1995, repayment in full of
the outstanding balance of the Company's line of credit in fiscal 1995 and the
cancellation of subordinated debt related to the exercise of warrants in
connection with the initial public offering.
Provision for Income Taxes. The effective tax rates for fiscal 1996 and 1995
were 33.9% and 35.3% respectively, and differed from the federal statutory
rate primarily because of benefits from the use of a foreign sales corporation
by the Company and state income taxes.

The Company's quarterly operating results have varied and may continue to
vary significantly due to a number of factors, including economic conditions
in the semiconductor and computer hard disk industries, the timing of
shipments of orders to major customers, the mix of products sold by the
Company and competitive pricing. Customers may cancel or reschedule shipments.
Production difficulties or the inability to obtain critical components could
delay shipments. These factors could have a material
18
<PAGE>
adverse effect on the Company's results of operations. As cost of revenue
includes manufacturing overhead, which is relatively constant from quarter to
quarter, gross margins can vary significantly from quarter to quarter due to
varying levels of production and revenue. There can be no assurance that the
Company will be profitable in any future period. Marketing and sales expenses
can vary from quarter to quarter based on a number of factors, including mix
of sales channels, geographic mix and timing of marketing events.

As of April 30, 1997, the Company had cash and cash equivalents of $19.4
million and working capital of $45.8 million. Net cash provided by operating
activities was $6.6 million. Net income was $13.2 million. This amount was
offset by a $4.4 million increase in accounts receivable resulting from
increased sales and a $8.6 million increase in inventory. Management believes
that inventory levels are larger than necessary for current sales volumes and
has instituted a number of programs to improve inventory turnover in all
facilities. Depreciation and amortization for fiscal 1997 was $1.6 million.
During fiscal 1997, the Company increased its ownership in its Japanese
distributor, Japan ADE Ltd. ("JAL"), from 3.0% to 50.0%. Consequently, in
fiscal 1997, $2.7 million in gross profit from sales to JAL have been deferred
rather than included in income from operations.
During fiscal 1997, $15.0 million of cash was used in investing activities.
Purchases of fixed assets represented $10.4 million of this amount. During the
next fiscal year, the Company does not anticipate investing in fixed assets to
the extent of fiscal 1997. Investments in three companies used an additional
$3.1 million.
Net cash provided by financing activities was $6.3 million. The primary
source of this cash was a $5.5 million Industrial Development Bond used to
finance the purchase and renovation of the manufacturing facility in Westwood,
Massachusetts.
Since inception, the Company has satisfied its cash requirements primarily
through cash flow from operations, private placements and an initial public
offering of the Company's Common Stock, bank borrowings and equipment
financing.
The Company may use a portion of the net proceeds from this offering for
acquisitions of complementary businesses and technologies. The Company
believes that cash from operations, existing cash resources and bank
borrowings, together with the net proceeds of the sale of Common Stock by the
Company in this offering, will be adequate to fund operations for at least the
next 18 months.
The Company's long-term capital requirements will be affected by many
factors, including the success of the Company's current product offerings, the
Company's ability to enhance its current products and to develop and introduce
new products that keep pace with technological developments and general trends
in the semiconductor wafer and device industries. The Company plans to finance
its long-term capital needs with the net proceeds of this offering, together
with existing cash reserves and interest earned thereon, revenue from product
sales, bank loans, leases and debt financings. To the extent that such funds
are insufficient to finance the Company's activities, the Company will have to
raise additional funds through the issuance of additional equity or debt
securities or through other means. There can be no assurance that additional
financing will be available on acceptable terms.
NEW ACCOUNTING PRONOUNCEMENTS
In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per
Share." This statement establishes and simplifies standards for computing and
presenting earnings per share. SFAS No. 128 will be effective beginning with
the Company's quarter ended January 31, 1998 and requires the restatement of
all previously reported
19
<PAGE>
earnings per share data that are presented. Early adoption of SFAS No. 128 is
not permitted. SFAS No. 128 replaces primary and fully diluted earnings per
share with basic and diluted earnings per share. Pro forma earnings per share
under SFAS No. 128 would have been as follows:
<TABLE>

</TABLE>
In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." The statement establishes standards for the reporting and display of
comprehensive income and its components. Comprehensive income is defined as
the change in equity of a business enterprise during a period from
transactions and other events and circumstances from non-owner sources. It
includes all changes in equity during a period except those resulting from
investments by owners and distributions to owners. This standard will require
that an enterprise display an amount representing total comprehensive income
for the period. SFAS No. 130 will be effective for the Company's fiscal year
ending April 30, 1998. Adoption of SFAS No. 130 is not expected to
significantly impact the Company's financial position or results of
operations.
In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information" which supersedes SFAS No. 14. This
statement changes the way that public business enterprises report segment
information, including financial and descriptive information about their
operating segments, in annual financial statements and would require that
those enterprises report selected segment information in interim financial
reports to stockholders. Operating segments are defined as revenue-producing
components of the enterprise which are generally used internally for
evaluating segment performance. SFAS No. 131 will be effective for the Company
beginning with the Company's fiscal year ending April 30, 1998. Adoption of
SFAS No. 131 will not impact the Company's financial position or results of
operations.
INFLATION
To date, inflation has not had a significant impact on the Company's

BUSINESS
OVERVIEW
ADE Corporation is a leader in the design, manufacture, marketing and
service of metrology and inspection systems for the semiconductor wafer
manufacturing industry. In addition, the Company is a growing supplier of
metrology systems to the semiconductor device and computer hard disk
industries. The Company's systems analyze and report product quality at
critical manufacturing process steps, sort wafers and disks and provide
manufacturers with quality certification data. Semiconductor wafer and device
and computer hard disk manufacturers use the Company's systems to improve
yield and capital productivity. The Company's products have evolved from
single instruments used in off-line engineering analysis to multi-function
systems for automated in-line monitoring of process-induced defects throughout
the wafer and disk manufacturing processes. The Company's systems are designed
to deliver the high throughput, reliability and information delivery and
analysis necessary to meet the demands of increasingly complex and time-
sensitive manufacturing processes. The Company has over 35 major products
currently in use by the wafer, device and disk manufacturing industries and
has shipped more than 1,700 systems.
INDUSTRY BACKGROUND
Semiconductor Wafer Manufacturing
The manufacture of a semiconductor device, or "chip", begins with the
production of a semiconductor wafer by a wafer manufacturer and is followed by
the fabrication of integrated circuits on the surface of the wafer by a
semiconductor device manufacturer. Wafer manufacturing is a highly
competitive, commodity business in which facilities operate 24 hours per day,
seven days per week. Any interruption in the supply of wafers to a device
customer can cause that customer to suffer substantial losses.
The wafer manufacturing process is largely mechanical. Measurements are
taken at various stages of the process to identify defects induced by the
manufacturing process, to eliminate unsatisfactory wafer materials from the
process stream and to sort the wafers into batches of uniform thickness to
increase productivity in the next process steps. Use by the wafer manufacturer
of advanced metrology and inspection equipment is essential to maintaining an
uninterrupted flow of ultra-flat, high-quality wafers. Advanced metrology and
inspection equipment provides data to wafer manufacturers which allow them to
identify sources of defects on wafers and to determine methods for controlling
such defect sources in a manner which optimizes productivity, quality and,
ultimately, wafer manufacturing profitability. This equipment must be reliable
and accurate and meet the demanding resolution and repeatability performance
requirements of the industry. As the industry moves to larger wafer sizes and
more advanced technologies, including the use of Epi wafers, the demand for
metrology and inspection systems meeting the above criteria is increasing.
Contamination of the wafer by dust, bacteria, metal particles from the
process or other foreign materials must be monitored and controlled because it
can damage or ruin the wafer. Any steps in the process which involve human
contact increase the level of contamination. The wafer manufacturing industry
seeks to use automated systems wherever possible to reduce this contamination.
The Company believes that semiconductor wafer manufacturers will continue to
further automate existing measurement processes, to improve accuracy and
repeatability over that offered by human operators. In addition, automating
the visual inspection steps at the end of both the Epi and prime processes, as
depicted in the chart below, could reduce manufacturing costs. Automating this
step requires new types of surface defect monitoring systems and enhancements
to existing measurement and inspection systems.
21
<PAGE>
The following is a summary of the steps in a typical wafer manufacturing
process.
[DIAGRAM OF THE STEPS IN A TYPICAL WAFER
MANUFACTURING PROCESS APPEARS HERE]
Semiconductor Device Fabrication
In order to facilitate commercial transactions between the wafer
manufacturer and the device manufacturer, Semiconductor Equipment and
Materials International ("SEMI"), an industry standards organization, has
developed the Silicon Wafer Order Form ("SWOF"), which identifies more than 40
independent parameters that may be specified, controlled and certified.
Incoming wafers are generally sample inspected to ensure that they comply with
the SWOF parameters specified by the device manufacturer. This inspection is
typically done using automated systems of the same type used by the wafer
manufacturer for outgoing inspection.
Following inspection, multiple layers are created on the surface of the
wafer through repeated photolithographic cycles. Multiple processing cycles
result in microtopographical variations which may significantly interfere with
photolithography. Successful photolithography requires extreme wafer flatness
and freedom from optical surface defects. The CMP process, recently adopted by
many leading device manufacturers, reflattens the wafer prior to many of the
photolithographic cycles. CMP may be used multiple times during the device
fabrication process. CMP, however, can leave process-induced defects on the
wafer surface. Measurements are made to ensure that the flatness of the wafers
entering each process cycle is suitable and to control other optical defect-
related trends during processing which, if
22
<PAGE>
unchecked, lead to reduced yield and higher per-unit costs. Finally,
measurement and control of the "backgrind" process used to produce thinner
chips for notebook computers, PCMCIA devices and "smart" cards is critical to
device yield.
Yield management is an area of growing importance in the device fabrication
process. As a consequence, yield management software tools are emerging which
integrate and analyze data produced by automated defect classification and
particle inspection tools.
Computer Hard Disk Manufacturing
Computer hard disk drives consist of a spindle, on which one or more hard
disks are mounted, and read-write "flying heads" (generally, two per disk)
which write data onto the surface of the disk and, thereafter, read back the
data for use in the computer. MR head technology has placed rigorous new
demands on magnetic data storage disk specifications. Higher density disks are
more vulnerable to variability in manufacturing processes. Process variations,
which in the past had negligible effects on disk yield, can render disks
intended for advanced MR technology data storage useless.
The computer hard disk manufacturing process, like the semiconductor wafer
manufacturing process, is largely mechanical. Hard disks, like wafers, are
delicate, flat, round and thin. They are commodity products made in very large
volumes, and are subject to many of the same yield loss problems that result
from manufacturing process variations. Disk manufacturing lines operate all
over the world, 24 hours per day, seven days a week, placing a premium on
equipment up-time and worldwide support. As the pace of disk drive technology
has continued to accelerate, hard disk manufacturers, who had previously used
internally developed solutions, are instead looking to outside vendors of
automated in-line metrology and inspection equipment.
Off-line, quality control lab measurements are taken at various stages of
the process in order to qualify and manage the process. These measurements are
moving in-line, as normal process variations lead to unacceptable yield loss
in the manufacture of disks for the latest MR technology disk drives. These
in-line measurements are utilized to identify defects induced by the
manufacturing process, to eliminate unsatisfactory disks from the process
stream and to sort the disks into batches of uniform thickness to increase
productivity in the next process step. Contamination of the disk by dust,
metal particles from the process or other foreign materials must be monitored
and controlled because it can damage or ruin the disk. Any steps in the
process which involve human contact increase the level of contamination. The
disk manufacturing industry seeks to use automated systems wherever possible
to reduce this contamination.

THE ADE STRATEGY
The Company intends to maintain its leadership position in the design,
manufacture, marketing and service of metrology and inspection systems for the
wafer manufacturing industry. The Company also recognizes an increasing need
for metrology and inspection equipment in the computer hard disk and
semiconductor device manufacturing industries and intends to increase its
penetration in these areas. In order to achieve these objectives, the Company
is pursuing the following strategies:
Broaden and Integrate Metrology and Inspection. Through internal development
and acquisitions, the Company continues to increase the number and type of
metrology and inspection functions that its products perform. The Company also
intends to automate functions currently performed by human inspectors and to
integrate them with existing automated functions into fully automated
workcells. These product line goals are intended to maximize yields and reduce
costs by eliminating process steps, replacing human inspectors and reducing
contamination.
Leverage Automated Metrology Capability into Device and Hard Disk Markets.
The Company believes that its existing technologies are well-suited for
emerging metrology and inspection requirements in the device fabrication and
computer hard disk manufacturing processes. The Company is developing software
to enable its existing measurement tools to support new applications in the
device fabrication process. In the hard disk industry, the Company is
broadening the functions its products perform and developing automated, in-
line production capacity systems.
Provide Yield Management Software Solutions. The Company is committed to
providing software solutions which increase its customers' yield management
and capital productivity. The Company's MicroSpec Automated Defect
Classification System is well-suited to meet the device manufacturing
industry's growing need to replace human classification of patterned wafer
defects with automatic defect classification. In addition, the Company
continues to develop information management software tools to further
integrate its systems with manufacturers' information systems.
Leverage Strong Customer Relationships and Emphasize Worldwide Service and
Support. The Company's product development plans are driven by an intimate
knowledge of its customers' development plans and process requirements, which
is developed through frequent contact between the customers and the Company's
technology, engineering, marketing, sales and management personnel. In
addition, the Company makes uninterrupted, uniform worldwide service available
to support its customers' requirements for extreme reliability and continuous
equipment up-time. The Company's dedicated service and applications staff and
affiliated distributors in Japan and the Far East provide timely and efficient
customer service and support worldwide. The Company believes that its
worldwide service organization is an important competitive advantage.
Maintain Technological Leadership. The Company intends to maintain its
technological leadership position by continuing its research and product
development activities and acquiring complementary businesses and
technologies. The Company seeks to protect its intellectual property through a
strong patent program. Technological innovation in the areas of non-contact
capacitive metrology, laser/optical based surface metrology and automation
systems has been critical to the Company's success. The Company intends to
expand its proprietary model-based design methodology and to continue adding
key technologists.

PRODUCTS
ADE's product strategy is to develop versatile, modular instrumentation and
automation sub-systems that can be assembled to form a number of integrated
products. These products support multiple metrology and inspection functions
and sorting in the semiconductor wafer and device and hard disk fabrication
processes. The Company has over 35 major products currently in use by the
semiconductor wafer and device and hard disk manufacturing industries and has
shipped more than 1,700 systems. During the past fiscal year, semiconductor
equipment sales to wafer manufacturers have generated approximately 77% of the
Company's annual revenues. The Company, however, must continue to develop and
introduce new products and product enhancements to keep pace with
technological developments and changing customer requirements. See "Risk
Factors--Rapid Technological Change and Introduction of New Products."
The Company's principal products in the semiconductor wafer, semiconductor
device and computer hard disk and disk drive industries and OEM automation are
described below. All metrology and inspection systems have the capability to
record, print and store measurement data locally, as well as distribute the
data via a network for yield and process management, future analysis and SWOF
quality certification.

TECHNOLOGY
The Company's metrology and inspection products use its proprietary non-
contact capacitive, magnetic and optical technologies to measure the
dimensional, magnetic and surface characteristics of semiconductor wafers and
devices and hard disks.
Dimensional Technology
The Company's non-contact capacitive gaging technology, which is the subject
of a series of patents, is used to measure the dimensional parameters
(thickness, flatness, shape) of semiconductor wafers, computer hard disks and
other objects. Non-contact technology has largely displaced traditional
contact gages, which can damage the wafer through physical contact.
The Company's capacitive dimensional gaging technology is based on the
measurement of the capacitance between a measurement probe and the surface of
the object. The capacitance varies as a precise function of the distance
between the probe and the object being measured, permitting the distance to be
measured with a precision of better than 0.01 microns. For example, in the
measurement of a semiconductor wafer, two probes, one on each side of the
wafer, map both wafer surfaces simultaneously. Electronic circuitry converts
the probe capacitance signal into distance signals which are translated by the
Company's software to produce information concerning the wafer's thickness,
flatness and shape.
ADE's capacitive dimensional technology has a number of advantages over
other non-contact measurement methods. Unlike optical, magnetic or acoustic
technologies, capacitive gaging is not significantly affected by environmental
conditions such as temperature and humidity or by the optical properties and
material characteristics of the wafer. As a result, the Company believes that
its capacitive dimensional technology provides a superior combination of
accuracy, precision and stability, greater bandwidth and a broader range of
potential applications than these other technologies.
Surface Inspection Technology
The Company uses optical methods to detect microscopic surface defects. A
finely focused laser beam is scanned over the surface of the wafer. Surface
particles or defects cause some of the beam's energy to scatter. Sensitive
detectors quantify this scattering signal, which is translated by the
Company's software to produce information about particles, microscratches,
haze and other process induced defects on the wafer surface. Although the
principles of the Company's optical technology are similar to those used by
other manufacturers, the Company believes its theoretical modeling and
patented optical engineering and proprietary software result in products
having a superior combination of high sensitivity and throughput.
Fourier Transform Infrared Spectroscopy Technology
Fourier Transform Infrared Spectroscopy Technology ("FTIR") is used in a
broad range of laboratory applications for examining various technical
properties of materials and chemicals. On-Line Technologies, Inc., a
Connecticut-based technology company, has licensed its FTIR technology to ADE
for incorporation into metrology tools for the wafer market.
ADE is integrating this technology, which primarily has been confined to
laboratory devices, as a metrology module into its automated in-line metrology
tools in order to provide the increasing precision and accuracy needed to
support the SWOF in the face of ever-tightening Epi specifications.
Magnetics Characterization Technology
The Company's products for characterizing magnetic materials use a variety
of non-contact measurement technologies including lasers (the Kerr effect),
vibrating sample and torque-effect inductive sensing techniques. The Company
believes its theoretical modeling and magnetics engineering enable it to offer
automated products with superior sensitivity, speed, accuracy, and
reproducibility.

Proprietary Software
ADE's proprietary software analyzes and transforms the large amounts of data
generated by ADE's metrology and inspection systems to produce information
about process induced defects that aids in process control. The flexible
design of the software permits reconfiguration of the Company's products to
serve new applications with a minimum of hardware or software redesign or
development. The Company's software is designed to integrate the Company's
various metrology functions with one another and to implement industry
standards for integrating the Company's products with the manufacturing
facility's information systems. The Company currently is seeking patent
protection on certain features of its software.
MARKETING, SALES AND CUSTOMER SUPPORT
The Company markets and sells its semiconductor metrology and inspection
products through its direct sales force, distributors and independent sales
representatives. The Company markets and sells its metrology and inspection
products in the United States, Europe and Malaysia through full-time
salespersons located in Milpitas, Dallas, Portland and Boston, in the United
States, in the United Kingdom, in Germany, and in Malaysia. During the past
fiscal year, approximately 50% of the Company's revenues were derived through
its direct sales organization. The Company's direct sales force is supported
by applications engineers in selected field offices and in its manufacturing
locations.
Sales of dimensional systems in Japan are supported by Japan ADE Limited, a
joint venture of the Company and Kanematsu Electronics, Ltd. Sales of optical
surface inspection products are provided in Japan by a separate distributor.
The Company also sells its semiconductor metrology and inspection products in
Israel, South Korea, Singapore, Taiwan, India and the People's Republic of
China through independent sales representatives. The Company markets and sells
its computer hard disk products in the United States through two full-time
salespersons and internationally through distributors and sales
representatives. The Company's gaging products are sold worldwide through
distributors and independent sales representatives.
The selling process for the Company's products frequently involves
participation by sales, marketing and customer support personnel. Customers
and potential customers often evaluate the Company's products by sending
semiconductor wafers to the Company for measurement or by installing
demonstration equipment at their facilities. The Company maintains
demonstration equipment at its manufacturing sites and some of its sales
offices for this purpose. The Company plans to increase its investment in
demonstration equipment to accelerate the introduction of products. The
Company's marketing activities also include participation in international
standards organizations, trade shows, publication of articles in trade
journals, participation in industry forums and distribution of sales
literature.
The Company believes that its strong commitment to service is essential,
based on the growing complexity of the equipment used in the semiconductor
manufacturing process. This complexity makes it difficult for semiconductor
wafer and device manufacturers to maintain an internal workforce sufficiently
skilled and specialized to support the disparate equipment and technologies
used in their processes. ADE has customer support centers in Boston,
Charlotte, Austin, Dallas, Milpitas, Portland, Milton Keynes, England, Munich,
Germany and Kuala Lumpur, Malaysia. The Company's customer support and service
staff currently consists of 74 persons. In addition, the Company's
distributors and sales representatives provide customer support. ADE also
offers training programs and maintenance contracts for its customers. The
Company offers warranties of up to twelve months covering the performance and
reliability of its products. In each of the past four years, the Company was
selected as one of the "ten-best" semiconductor measurement equipment
manufacturers in the world in customer surveys conducted by VLSI Research Inc.

CUSTOMERS
The Company's customers include all of the leading semiconductor wafer
manufacturers and many of the leading semiconductor device and computer hard
disk and disk drive manufacturers throughout the world. Historically, a
relatively limited number of customers have accounted for a substantial
portion of the Company's revenues. In fiscal years 1995, 1996 and 1997, sales
to the Company's top five customers accounted for approximately 51%, 45% and
50%, respectively, of the Company's revenue. During fiscal year 1997, one of
the Company's customers accounted for 16% of the Company's revenue. See "Risk
Factors--Customer and Industry Concentration." During the past fiscal year,
approximately 77% of the Company's revenues were derived from sales made to
wafer manufacturers, with the remainder of the Company's revenues derived from
sales to manufacturers of semiconductor devices, and computer hard disks and
disk drives and semiconductor equipment. The Company's principal customers are
as follows:
SEMICONDUCTOR WAFER MANUFACTURERS

RESEARCH AND DEVELOPMENT
The market for semiconductor wafer and device and computer hard disk and
disk drive equipment is characterized by rapid technological change and
product innovation. The Company's research and development efforts are
designed to enhance the Company's current products and develop and introduce
new products to keep pace with technological developments and respond to
constantly evolving customer requirements. The Company devotes significant
resources to programs directed towards developing new and enhanced products,
as well as developing new applications for existing products.
As of April 30, 1997, the Company employed a full-time research and
development staff of 131 persons. In fiscal years 1995, 1996 and 1997, the
Company's research and development expenditures
31
<PAGE>
were $6.3 million, $7.8 million and $17.0 million respectively, representing
13.7%, 11.6% and 16.8% of revenues. Research and development expenditures
consist primarily of salaries, project materials and other costs associated
with the Company's ongoing research and development efforts. See "Risk
Factors--Rapid Technological Change and Introduction of New Products."
Industry standards organizations, such as SEMI and American Standards for
Testing and Materials ("ASTM"), are pivotal in defining the test methods,
measurement parameters and specifications governing commercial transactions
within the semiconductor industry. The Company maintains a significant
presence on standards committees of SEMI, ASTM and other international
standards organizations. The Company believes that its involvement with these
organizations has helped to ensure that the Company's new products conform to
industry standards.
BACKLOG
At April 30, 1997, the Company's backlog was approximately $61 million. The
Company schedules production based on firm customer commitments and
anticipated orders during the planning cycle. The Company includes in its
backlog only those customer orders for which it has accepted written purchase
orders against which it expects to ship within the following twelve months.
All orders are subject to cancellation or delay by the customer with limited
or no penalty. The Company does not believe that the level of backlog is an
accurate indicator of the Company's future performance. See "Risk Factors--
Fluctuations of Quarterly Operating Results."
MANUFACTURING
The Company's principal manufacturing activities take place at its ISO 9001-
registered facility near Boston, Massachusetts, where dimensional metrology
systems are manufactured, and Charlotte, North Carolina, where optical surface
inspection equipment is manufactured. Certain of the Company's gaging products
for the computer disk and disk drive and other industries are manufactured in
Milpitas, California. Manufacturing activities consist primarily of assembling
and testing components and subassemblies which are supplied by third party
vendors and then integrated into the Company's finished products. Many of the
components and subassemblies are standard products, although certain items are
made to Company specifications. The Company manufactures its semiconductor
metrology and inspection systems in a cleanroom environment.
Certain components and subassemblies, including certain system controllers
and robotics components incorporated into the Company's systems, are obtained
from a single source or a limited group of suppliers. Management routinely
monitors single or limited source supply parts, and the Company endeavors to
ensure that adequate inventory is available to maintain manufacturing
schedules should the supply of any part be interrupted. Although the Company
seeks to reduce its dependence on sole and limited source suppliers, it has
not qualified a second source for these products and the partial or complete
loss of certain of these sources could have an adverse effect on the Company's
results of operations and damage customer relationships. See "Risk Factors--
Dependence on Suppliers." Further, a significant increase in the list price of
one or more of these components could adversely affect the Company's results
of operations.
COMPETITION
The semiconductor and computer hard disk equipment industries are highly
competitive. While the Company believes that it does not presently have
significant established competitors in the metrology area of the semiconductor
wafer equipment industry, there can be no assurance that companies with
complementary technologies and greater financial resources will not enter the
industry and develop products that are superior to the Company's products or
achieve market acceptance. In the market for optical defect inspection
equipment, the Company competes directly with Hitachi Electronics Engineering
32
<PAGE>
Co., Ltd. and KLA-Tencor Corporation, both of which have significantly greater
financial resources than the Company. In the metrology area of the device
industry, the Company has encountered, and expects to encounter in the future,
competition from companies offering similar and competing technologies, some
of which have significantly greater financial resources than the Company or an
existing market presence in the device industry, or both. The Company also
expects to encounter intense competition in the areas of metrology and
inspection for the hard disk industry. The Company's competitors can be
expected to continue to improve the design and performance of their products
and to introduce new products with competitive price/performance
characteristics. Competitive pressures can necessitate price reduction which
can adversely affect operating results. Although the Company believes that it
has certain technical and other advantages over its competitors, maintaining
such advantages will require a continued high level of investment by the
Company in research and development and sales, marketing and service. There
can be no assurance that the Company will have sufficient resources to
continue to make such investment or that the Company will be able to make the
technological advances necessary to maintain such competitive advantages.
PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS
The Company relies on a combination of patent, copyright, trademark and
trade secret laws and license agreements to establish and protect its
proprietary rights in its products. The Company believes, however, that its
success depends to a greater extent upon innovation, technological expertise
and distribution strength. The Company requires each of its employees,
including its executive officers, to enter into standard employee agreements
pursuant to which the employee agrees to keep confidential all proprietary
information of the Company and to assign to the Company all rights in any
proprietary information or technology made or contributed by the employee
during his or her employment or made thereafter as a result of any inventions
conceived or work done during such employment. Despite these precautions, it
may be possible for a third party to copy or otherwise obtain and use the
Company's products or technology without authorization or to develop similar
technology independently. In addition, effective patent, copyright and trade
secret protection may be unavailable or limited in certain foreign countries.
The Company currently holds 26 United States patents and 15 foreign patents
covering existing and potential products and has applied for 4 additional
patents in the United States and 13 additional foreign patents.
The Company has licensed its prealigner patents to a number of companies
following the settlement of a patent infringement suit brought by the Company.
The Company is actively pursuing similar licensing arrangements with a number
of other companies.
As is typical in the Company's industry, the Company and its customers from
time to time receive letters from third parties, including some of the
Company's competitors, alleging infringement of such parties' patent rights by
the Company's products. There can be no assurance that the Company would
prevail in any litigation seeking damages or expenses from the Company or to
enjoin the Company from selling its products on the basis of such alleged
infringement or that the Company would be able to license any valid and
infringed patents on reasonable terms. See "Risk Factors--Patents and Other
Intellectual Property."
EMPLOYEES
As of April 30, 1997, the Company employed a total of 538 persons at all of
its locations, including 227 in manufacturing, 131 in research and
development, 50 in marketing and sales, 74 in customer service and 56 in
administration.
Management believes that the Company's ongoing success depends on its
continued ability to attract and retain highly skilled employees. There can be
no assurance that the Company will be successful in attracting or retaining
such personnel. None of the Company's employees is represented by a labor
union,
33
<PAGE>
and the Company has experienced no work stoppages. The Company considers its
employee relations to be good.
FACILITIES
The Company's principal operations are located in an approximately 117,000
square foot company-owned building in Westwood, Massachusetts; a 46,000 square
foot building in Newton, Massachusetts under a five-year lease that expires in
May 2002; and a 38,000 square foot building in Charlotte, North Carolina under
a ten-year lease that expires in September 2004. The Company also owns a
14,400 square foot building in Burlington, Massachusetts and leases space for
sales and customer support offices in various other locations.

</TABLE>
The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will
purchase all shares of the Common Stock offered hereby if any of such shares
are purchased.
The Company and the Selling Stockholders have been advised by the
Representatives of the Underwriters that the Underwriters propose to offer the
shares of Common Stock to the public at the public offering price set forth on
the cover page of this Prospectus and to certain dealers at such price less a
concession not in excess of $0.96 per share. The Underwriters may allow, and
certain dealers may reallow, a concession not in excess of $0.10 per share to
certain other dealers. After the public offering, the offering price and other
selling terms may be changed by the Representatives of the Underwriters.
The Company and the Selling Stockholders have granted to the Underwriters an
option, exercisable not later than 30 days after the date of this Prospectus,
to purchase up to 370,500 additional shares of Common Stock at the public
offering price less the underwriting discounts and commissions set forth on
the cover page of this Prospectus. To the extent that the Underwriters
exercise such option, each of the Underwriters will have a firm commitment to
purchase approximately the same percentage thereof that the number of shares
of Common Stock to be purchased by it shown in the above table bears to
2,470,000 and the Company and the Selling Stockholders will be obligated,
pursuant to the option, to sell such shares to the Underwriters. The
Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of Common Stock hereby. If purchased, the
Underwriters will offer such additional shares on the same terms as those on
which the 2,470,000 shares are being offered.
The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act.
The Company, the Selling Stockholders, and all executive officers and
directors of the Company, who in the aggregate will hold 3,466,564 shares of
Common Stock and options to purchase 307,926 shares of Common Stock after this
offering, have agreed not to, directly or indirectly, offer, sell, contract to
sell or otherwise dispose of any shares of Common Stock beneficially owned by
them for a period of 90 days after the date of this Prospectus without the
prior written consent of Alex. Brown & Sons Incorporated.
In connection with the Offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions, "passive" market making and purchases to cover
syndicate short positions created in connection with the Offering. Stabilizing
transactions consist of certain bids or purchases made for the purpose of
preventing or
39
<PAGE>
retarding a decline in the market price of the Common Stock. Syndicate short
positions involve the sale by the Underwriters of a greater number of shares
of Common Stock than they are required to purchase from the Company in the
Offering. The Underwriters also may impose a penalty bid, whereby the
syndicate may reclaim selling concessions allowed to syndicate members or
other broker-dealers in respect of the Common Stock sold in the Offering for
their account if the syndicate repurchases the shares in stabilizing or
covering transactions. These activities may stabilize, maintain or otherwise
affect the market price of the Common Stock, which may be higher than the
price that might otherwise prevail in the open market. These activities, if
commenced, may be discontinued at any time. These transactions may be effected
on the Nasdaq National Market, in the over-the-counter market or otherwise.
As permitted by Rule 103 under the Exchange Act, Underwriters or prospective
Underwriters that are market makers (passive market makers) in the Common
Stock may make bids for or purchases of shares of Common Stock in the Nasdaq

REPORT OF INDEPENDENT ACCOUNTANTS
To the Board of Directors and Stockholders
of ADE Corporation
In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of ADE
Corporation and its subsidiaries at April 30, 1996 and 1997, and the results
of their operations and their cash flows for each of the three years in the
period ended April 30, 1997, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

ADE CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
1. NATURE OF BUSINESS
ADE Corporation (the "Company") designs, manufactures, markets and services
highly precise, automated measurement, defect detection and handling equipment
with current applications in the production of semiconductor wafers,
integrated circuits and computer memory disks. The predominant market for the
Company consists of semiconductor wafer and device manufacturing concerns
located in the United States, Japan, Europe and the Far East.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
A summary of significant accounting policies followed in the preparation of
the financial statements follows:
Principles of Consolidation
The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. Effective February 28, 1997, the Company
acquired all of the outstanding shares of common stock of Digital Measurement
Systems, Inc. ("DMS") in exchange for 821,000 shares of common stock of the
Company. This transaction has been accounted for as a pooling-of-interests
and, therefore, the accompanying financial statements have been retroactively
restated to reflect the financial position and results of operations and cash
flows of the Company and DMS for all periods presented (Note 3). All material
intercompany transactions and balances have been eliminated.
Investments in 50% or less owned companies over which the Company has the
ability to exercise significant influence are accounted for using the equity
method. Investments in 20% or less owned companies are accounted for using the
cost method. (Note 4)
Revenue Recognition
Revenue from product sales is recorded upon shipment. The Company accrues
for anticipated warranty costs upon shipment. Service revenue is recognized as
the services are performed. The Company does not provide the right to return
products.
Revenue under certain long-term contracts containing custom engineering is
recognized under the percentage-of-completion method. The percentage of
completion is determined by relating the actual cost of the work performed to
date to the estimated total cost of the respective contracts. Contract costs
include all direct material and labor costs as well as an allocated share of
indirect costs incurred. Actual costs incurred and estimated earnings on
contracts in progress at year end are included in operations for the year.
Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. The Company
invests its excess cash in money market accounts. These investments are
subject to minimal credit and market risks. At April 30, 1996 and 1997, the
Company has classified its cash equivalent investments totaling $18,092 and
$10,465, respectively, as available for sale. The carrying amount of these
investments approximates fair market value.

ADE CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
Inventories
Inventories are stated at the lower of cost or market, cost being determined
on a first-in, first-out basis.
Fixed Assets
Fixed assets are stated at cost. Additions and betterments, unless of a
relatively minor amount, are capitalized. Expenditures for normal maintenance
and repairs are charged to expense as incurred. Depreciation is provided by
use of the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are amortized over the shorter of their useful life or
the remaining life of the lease.
Excess of Net Assets Acquired Over Cost
The excess of net assets acquired over cost represents the unamortized
excess of the fair market value of the net assets acquired determined at the
date ADE Optical Systems, Inc. ("AOS") was acquired over the purchase price of
AOS, after reducing the basis in noncurrent assets acquired to zero. The
original amount of the excess of net assets acquired over cost is being
amortized using the straight-line method over five years.
Concentrations
Credit Risk
Financial instruments which potentially expose the Company to concentration
of credit risk include cash, cash equivalents and trade accounts receivable. A
significant amount of the Company's cash and cash equivalents are held by four
financial institutions. Accounts at each institution are insured by the
Federal Deposit Insurance Corporation up to $100. Uninsured cash balances
totaled approximately $2,859 and $8,117 at April 30, 1996 and 1997,
respectively. The Company does not believe that such deposits are subject to
any unusual credit risk associated with operating its business.
The Company's customer base primarily consists of semiconductor wafer,
semiconductor device and computer hard disk manufacturers. Accounts receivable
from two customers accounted for approximately 42% and 36% of total accounts
receivable at April 30, 1996 and 1997, respectively. The Company performs
ongoing credit evaluations of customers' financial condition, although
collateral is not required. In addition, the Company maintains reserves for
potential credit losses and such losses, in aggregate, have not exceeded
management expectations.
Suppliers
Certain of the components and subassemblies incorporated into the Company's
systems are obtained from a single source or a limited group of suppliers. The
Company seeks to reduce the impact from its dependence on those sole and
limited source suppliers by considering alternate sources of supply, alternate
designs for its products and by maintaining an adequate supply of the
components and subassemblies. However, the loss of one or more of the sole or
limited suppliers could cause a delay in manufacturing and a potential loss of
sales, which could affect operating results adversely.
Financial Instruments
The carrying amount of the Company's financial instruments, which include
cash, cash equivalents, accounts receivable, accounts payable, accrued
expenses, and long-term debt, approximates their fair value at the balance
sheet dates. It was not practicable to estimate the fair value of the
Company's long-term investments as the stock of the related investees is not
publicly traded.

ADE CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
Stock-Based Compensation
Stock-based compensation awards to employees under the Company's stock plans
are accounted for using the intrinsic value method prescribed in Accounting
Principles Board Opinion ("APB") No.25, Accounting for Stock Issued to
Employees and related interpretations. The Company has adopted the disclosure
requirements of Statement of Financial Accounting Standards ("SFAS") No. 123,
"Accounting for Stock-Based Compensation."
Earnings Per Share
Earnings per share are determined by dividing net income by the weighted
average number of common shares and common share equivalents outstanding
during the year. Common share equivalents consist of common stock which may be
issuable upon exercise of outstanding stock options and warrants using the
treasury stock method. Common stock, warrants and options issued or granted at
prices below the initial public offering price per share during the twelve-
month period prior to the initial filing of the Company's registration
statement on Form S-1 have been included in the calculation as if outstanding
for all periods presented through July 31, 1995 using the treasury stock
method and the initial public offering price of $14.00 per share.
Use of Estimates
The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and
disclosure of contingencies at April 30, 1996 and 1997, and the reported
amounts of revenues and expenses during the three year period ended April 30,
1997. Actual results could differ from those estimates.
New Accounting Pronouncements
In February 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, "Earnings Per Share." This statement establishes and simplifies
standards for computing and presenting earnings per share. SFAS No. 128 will
be effective beginning with the Company's quarter ended January 31, 1998 and
requires the restatement of all previously reported earnings per share data
that are presented. Early adoption of SFAS No. 128 is not permitted. SFAS No.
128 replaces primary and fully diluted earnings per share with basic and
diluted earnings per share. Pro forma earnings per share under SFAS No. 128
would have been as follows:

Pro forma diluted net income per share................. 0.47 0.98 1.48
</TABLE>
In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." The statement establishes standards for the reporting and display of
comprehensive income and its components. Comprehensive income is defined as
the change in equity of a business enterprise during a period from
transactions and other events and circumstances from non-owner sources. It
includes all changes in equity during a period except those resulting from
investments by owners and distributions to owners. This standard will require
that an enterprise display an amount representing total comprehensive income
for

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
the period. SFAS No. 130 will be effective for the Company's fiscal year
ending April 30, 1998. Adoption of SFAS No. 130 is not expected to
significantly impact the Company's financial position or results of
operations.
In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information" which supersedes SFAS No. 14. This
statement changes the way that public business enterprises report segment
information, including financial and descriptive information about their
operating segments, in annual financial statements and would require that
those enterprises report selected segment information in interim financial
reports to stockholders. Operating segments are defined as revenue-producing
components of the enterprise which are generally used internally for
evaluating segment performance. SFAS No. 131 will be effective for the Company
beginning with the Company's fiscal year ending April 30, 1998. Adoption of
SFAS No. 131 will not impact the Company's financial position or results of
operations.
3. ACQUISITION; POOLING-OF-INTERESTS
On February 28, 1997, pursuant to an Agreement and Plan of Merger (the "DMS
Agreement"), the Company, through its wholly-owned subsidiary ADE
Technologies, Inc. ("ATI"), acquired Digital Measurement Systems, Inc.
("DMS"), a Massachusetts corporation, and a building which is integral to the
operations of DMS and which was controlled by a significant stockholder of
DMS. DMS designs, manufactures, markets and services magnetic measurement
devices with current applications in the production of computer memory disks.
Pursuant to the DMS Agreement, each outstanding share of DMS capital stock was
converted into 759.73 shares of the Company's common stock. Immediately prior
to the acquisition, there were 1,000 shares of DMS Class A common stock and 53
shares of DMS Class B common stock outstanding. Pursuant to the terms of the
DMS Agreement, the Company also issued 21,000 shares in connection with the
acquisition of the building. In total, 821,000 shares of the Company's common
stock were issued in this transaction. This transaction has been accounted for
as a pooling-of-interests and, therefore, all prior period financial
statements presented have been restated as if the acquisition took place at
the beginning of such periods.
DMS had a March 31 year end and, accordingly, the results of operations for
DMS for the three years ended March 31, 1997 have been combined with the
results of operations for the Company's three years ended April 30, 1997.
Additionally, the financial position of DMS as of March 31, 1996 has been
combined with the Company's financial position as of April 30, 1996. In order
to conform DMS to the Company's fiscal year end, the financial position of DMS
and the Company have been combined as of April 30, 1997. Accordingly, an
adjustment has been made to retained earnings in fiscal 1997 to record the net
income of DMS for the one month period ended April 30, 1997 totaling $108.
Other results of operations for such one month period of DMS included revenues
of $684 and operating costs and expenses of $527.
There were no material transactions between the Company and DMS during any
of the periods presented prior to the DMS Agreement. All material intercompany
transactions and balances subsequent to the DMS Agreement have been
eliminated. No material adjustments to net assets or the results of operations
were necessary to conform the accounting practices of DMS to those of the
Company.

4. INVESTMENTS
The Company's investments of 50% or less owned companies over which the
Company has the ability to exercise significant influence are accounted for
using the equity method. Investments carried at equity consist of Japan ADE
Ltd. ("JAL"), a Japanese corporation, and Microspec Technologies Ltd.
("Microspec"), an Israeli corporation.
In July 1996, the Company acquired 1,410 shares of JAL for $1,300, which
increased the Company's investment in JAL from 3% to 50%. JAL has been the
exclusive distributor of ADE dimensional products in Japan since 1986. In
connection with this investment, JAL and the Company also agreed to reduce the
discount provided on sales to JAL. Sales to JAL which have not in turn been
sold to unrelated third parties at April 30, 1997 have been eliminated, and
the related profit on such sales is recorded as deferred income on sales to
affiliate.
In July 1996, the Company acquired a 25.1% interest in Microspec for $1,250.
In connection with this investment, the Company also executed an exclusive
five-year agreement to distribute Microspec products, subject to certain
performance criteria. During fiscal year 1997, there were no material
purchases from or sales to Microspec.

The Company's share of undistributed earnings of one affiliated company and
the Company's share of the losses of the other affiliated company included in
consolidated retained earnings was $507 and $136 at April 30, 1997,
respectively. The Company has received no dividends from affiliated companies
during fiscal year 1997. At April 30, 1997, the Company's investment exceeds
the underlying net assets of affiliated companies by $1,476, which is being
amortized by decreasing the equity in net earnings of affiliated companies
using the straight-line method over five years. Related amortization expense
of $273 was recorded in fiscal 1997.
Pro forma revenue, net income and net income per share as though the
investments in affiliated companies were made at the beginning of fiscal year
1996, including the effect of eliminating the profit on affiliated sales in
beginning and ending inventory for the period, have not been included as they
are not materially different from actual revenue, net income and net income
per share for the two years ended April 30, 1997.
The Company also has a less than 20% investment in a company in the amount
of $500 that is accounted for using the cost method.

8. BORROWINGS
Note Payable to Related Party
At April 30, 1996, the Company had a $577 note payable due to a company
affiliated with a principal stockholder of DMS, which bore interest at an
annual rate of 15%. Interest expense for the years ended April 30, 1995, 1996
and 1997 totaled $48, $88 and $87, respectively. During the year ended April
30, 1997, DMS repaid the entire principal on the note.
Long-term Debt
In June 1994, the Company entered into an agreement with a former executive
to purchase 34,430 shares of the Company's common stock by paying cash of $38
and issuing a promissory note payable for $114. The note bears interest at the
prime rate (8.5% at April 30, 1997) and the remaining principal balance of $38
at April 30, 1997 is payable on August 1, 1997.
Under the terms of the DMS Agreement, the Company assumed a mortgage loan
which was secured by the acquired building. The principal balance outstanding
totaled $645 and $639 at April 30, 1996 and 1997, respectively. The Company
paid the remaining principal balance in full in June 1997; accordingly, the
balance has been included in the current portion of long-term debt at April
30, 1997.
In June 1996, the Company issued a $5.5 million tax exempt Industrial
Development Bond through the Massachusetts Industrial Finance Agency. The bond
carries a 5.74% interest rate for 10 years with amortization of 50% of the
principal and with the remaining 50% due in June 2006. Monthly payments
consisting of principal and interest total $43. The proceeds of the bond were
used to fund the acquisition and renovation of the manufacturing facility in
the Company's new headquarters site. The Company secured the issuance of the
bond with a standby letter of credit from a financial institution. The standby
letter of credit, bearing a fee of 1.25% of the outstanding bond balance, is
secured by a mortgage on the building and land. Under the terms of the letter
of credit, the Company is required to comply with certain financial covenants.
Future maturities of this bond are as follows:

In December 1992, the Company entered into a $1,250 unsecured, Subordinated
Note and Warrant Purchase Agreement (the "Agreement") with a financial
institution. The subordinated note bore interest at 10% and was scheduled to
mature in November 1999. As part of the Agreement, the Company issued a
warrant for 325,000 shares of the Company's common stock at an exercise price
of $3.25 per share. Upon the closing of the Company's initial public offering,
the financial institution exercised the warrant through the cancellation of
$1,056 of related debt. The remaining outstanding principal of the note
totaling $131 was paid by the Company during fiscal 1996.

9. EMPLOYEE COMPENSATION PLANS
In 1982, the Company adopted the 1982 Stock Option Plan (the "1982 Plan")
which provided for the granting of incentive stock options and non-qualified
stock options through 1992 and was administered by a committee of the Board of
Directors (the "Compensation Committee"). The Company had reserved 900,000
shares of common stock for grant to employees under the 1982 Plan. In April
1992, the Company adopted the 1992 Stock Option Plan (the "1992 Plan"). The
1992 Plan provides for the issuance to employees of options to purchase
479,000 shares of common stock plus any expired or cancelled options granted
pursuant to the 1982 Plan. In August 1995, the Company adopted the 1995 Stock
Option Plan (the "1995 Plan"). The 1995 Plan provides for the issuance to
employees of stock options or stock awards to purchase 400,000 shares of
common stock. At April 30, 1997, 27,290 shares and 80,000 shares were
available for future grants under the 1992 Plan and the 1995 Plan,
respectively. Options are granted under the 1992 and 1995 Plan as either
incentive stock options or non-qualified stock options and at exercise prices
not less than the fair value of the stock on the date of grant or less than
110% of the fair value in the case of optionees holding more than 10% of the
total combined voting power of all classes of stock of the Company. The terms
of the options generally may not exceed ten years or five years in the case of
optionees holding more than 10% of the total combined voting power of all
classes of stock of the Company. The options are exercisable over periods
determined by the Compensation Committee, generally at the rate of 20% per
year, on a cumulative basis, beginning with the first anniversary of the date
of grant.
In October 1992, the Company granted non-qualified, fully vested stock
options to purchase 30,000 shares of the Company's common stock at an exercise
price of $4.15 per share. These options were not granted pursuant to either
the 1992 Plan or the 1982 Plan. These options are exercisable from the date of
grant through October 2002.
In October 1996, the Board of Directors adopted the Employee Stock Purchase
Plan (the "Purchase Plan") effective as of October 1, 1996. The Purchase Plan
provides its full-time employees, nearly all of whom are eligible to
participate, the opportunity to purchase common shares, on a quarterly basis,
at 85% of the fair market value of the shares on either the first or last day
of the applicable quarter, whichever is lower. The term of the Purchase Plan
is for five years, and the Company has authorized 1,000,000 shares of the
Company's common stock for issuance under the Purchase Plan. Under the
Purchase Plan, the Company sold 10,044 shares to employees in fiscal year
1997.

The Company applies APB No. 25 and related interpretations in accounting for
stock-based compensation. During fiscal years 1995 and 1996, the Company
recorded deferred compensation of $251 and $58, respectively, which is
equivalent to the difference between the fair market value of the underlying
securities and the exercise price of the related options granted. Such
compensation is being amortized over the vesting periods of the related
options. The Company has recognized no compensation expense in fiscal year
1995 and has recognized $50 and $55 in fiscal years 1996 and 1997,
respectively, for all of its stock-based compensation. Had compensation cost
for the stock-based compensation been determined based on the fair value at
the grant dates of awards consistent with the provisions of SFAS No. 123, the
Company's net income and earnings per share would have been reduced to the pro
forma amounts as follows:
<TABLE>

Net income per share:
As reported.............................................. $ 0.98 $ 1.48
Pro forma................................................ 0.98 1.46
</TABLE>
The fair value of each option and purchase right grant was estimated on the
grant date using the Black-Scholes option-pricing model with the following
weighted average assumptions for fiscal years 1996 and 1997: no dividend
yield; risk free interest rate of 5.7% and 6.4% in fiscal 1996 and 1997,
respectively; expected option term of 6 years and expected purchase right term
of three months; no volatility for options granted prior to the initial filing
of the Company's registration statement on Form S-1 in August 1995 and 50% for
options and purchase rights granted subsequent to August 1995. The weighted
average fair value per option for options granted with option exercise prices
equal to the fair value of the underlying common stock in fiscal years 1996
and 1997 was $8.09 and $7.25, respectively. The weighted average fair value
per option for options granted with exercise prices below the fair value of
the underlying common stock in fiscal year 1996 was $9.08. The weighted
average fair value per purchase right for purchase rights granted in fiscal
year 1997 was $2.82.
Because options vest over several years and additional option and purchase
right grants are expected to be made in subsequent years, the pro forma impact
on fiscal years 1996 and 1997 is not necessarily representative of the pro
forma effects of reported net income and earnings per share for future years.

Common Stock
On August 17, 1995, the stockholders of the Company increased the number of
authorized shares of common stock from 6,000,000 to 25,000,000 shares. On the
same date, the Board of Directors approved a 2-for-1 split of the common
shares to be effected in the form of a stock dividend on all issued stock
which was distributed on October 2, 1995. Accordingly, all share and per share
data have been restated for all periods presented to reflect the increase in
the authorized shares and the split. The par value of the additional shares of
common stock issued in connection with the stock split was credited to common
stock and a like amount was charged to capital in excess of par value.
