PRI AUTOMATION

We are a leading global supplier of advanced automation systems and software
for the semiconductor industry. We offer complete and flexible solutions that
address a wide range of automation requirements for semiconductor manufacturers
and for original equipment manufacturers, or OEMs, of semiconductor process
tools. Our factory automation systems and software help semiconductor
manufacturers optimize the flow of material and data throughout the
semiconductor fabrication facility, or fab, improving productivity and
increasing the manufacturer's return on investment. Our robotic wafer-handling
systems and software offer high-performance and reliability for OEM process tool
manufacturers, allowing them to focus on developing next generation process
technology. We also provide automation services, including equipment layout and
design, fab simulation, project management, installation and on-site support. We
sell and support our products through a global direct sales and support
organization operating out of offices in North America, Europe, Israel, Taiwan,
South Korea, Singapore, and Japan. Our customers include many of the world's
leading semiconductor manufacturers and semiconductor capital equipment
suppliers.

Semiconductor production is one of the most complex and logistically
challenging manufacturing operations in the world. As the complexity of advanced
semiconductor devices has increased, the capital expenditure required to build
or upgrade semiconductor manufacturing facilities has also grown, and the cost
of constructing and equipping a state-of-the-art production fab today can be in
excess of $1.5 billion. Advances in semiconductor technology, intensifying
competitive pressures and the need to improve the return on invested capital are
driving semiconductor manufacturers to seek ways to:

- increase wafer throughput while maintaining high product yields;

- lower production costs by maximizing utilization of facilities and process
tools;

- more efficiently manage the increasingly complex production process;

- respond more quickly and flexibly to changing customer requirements; and

- solve the ergonomic and logistical problems associated with 300mm wafer
manufacturing.

In an effort to address these challenges, semiconductor manufacturers have
in recent years sought to automate portions of their production processes to
reduce human handling and thereby improve production yields and throughput and
increase the efficiency of their operations. These efforts initially focused on
the automation of individual process tools. Subsequently, semiconductor
manufacturers have been adopting more comprehensive factory automation
strategies, including systems that automate the storage and movement of
materials throughout the fab. As a result, an increasing amount of semiconductor
capital equipment spending has been directed to factory automation systems.

We offer integrated factory automation solutions designed to enhance
productivity throughout the fab, thereby increasing return on investment and
overall factory effectiveness. We combine our advanced automation systems and
factory management software with a broad range of implementation services that
draw on our extensive domain expertise in the semiconductor fabrication process
to provide integrated automation solutions. By optimizing the flow of materials
and data throughout the fab, our products enable customers to more effectively
plan, schedule and carry out their production activity. Our hardware and
software products, ranging from tool automation systems and associated controls
to factory-wide automation systems and planning and scheduling software, are
designed to

3
<PAGE>
work together efficiently and to be easily installed and flexibly reconfigured.
Our products support industry standards, providing customers with the option of
purchasing our integrated factory automation solutions or incorporating elements
of our system into their existing fab automation infrastructure.

Our objective is to extend our position as the leading supplier of factory
automation solutions for semiconductor manufacturing. To achieve this objective,
we are pursuing a business strategy to:

- provide comprehensive factory automation solutions;

- strengthen our customer relationships;

- expand our product offerings;

- increase our penetration of the Asia-Pacific market; and

- exploit emerging 300mm wafer automation opportunities.

RISK FACTORS

YOU SHOULD CONSIDER CAREFULLY THE RISKS DESCRIBED BELOW BEFORE YOU DECIDE TO
BUY OUR COMMON STOCK. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE
ONLY ONES WE FACE. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCURS, OUR BUSINESS,
FINANCIAL CONDITION OR RESULTS OF OPERATIONS WOULD LIKELY SUFFER. IN THAT CASE,
THE TRADING PRICE OF OUR COMMON STOCK COULD FALL, AND YOU COULD LOSE ALL OR PART
OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK.

RISKS RELATED TO OUR BUSINESS

OVERSUPPLY IN THE SEMICONDUCTOR MARKET MAY IN THE FUTURE REDUCE DEMAND FOR
CAPITAL EQUIPMENT, INCLUDING FOR OUR SYSTEMS.

Our business depends heavily upon capital expenditures by semiconductor
manufacturers, particularly manufacturers that are opening or expanding
semiconductor fabrication facilities. These manufacturers frequently postpone or
abandon their plans to make capital expenditures when demand for their products
and products containing semiconductors is low. The semiconductor industry has
been highly cyclical, and periods of oversupply in the market for semiconductors
have caused significantly reduced demand for capital equipment, including
systems such as ours. We believe that this cyclicality will continue. In
addition, the recent high rate of technical innovation and resulting
improvements in the performance and price of semiconductor devices, which have
driven much of the demand for our products, could slow or encounter limits.

THE SEMICONDUCTOR INDUSTRY RECENTLY EXPERIENCED A DOWNTURN THAT ADVERSELY
AFFECTED OUR OPERATING RESULTS, AND REDUCED DEMAND FOR SEMICONDUCTORS IN THE
FUTURE COULD JEOPARDIZE OUR PLANS.

In recent years, the semiconductor industry experienced a significant
downturn, which seriously harmed our ability to sell our systems. The recent
downturn in the Asia-Pacific market also affected demand for semiconductor
manufacturing equipment, including our systems. These and other factors
significantly reduced our revenue and profitability in fiscal 1999. Our total
net revenue for fiscal 1999 was $136.3 million, compared with total net revenue
of $203.5 million in fiscal 1998. This decline occurred primarily in our factory
automation systems and tool automation systems businesses. In fiscal 1999, we
incurred a net loss of $36.1 million, compared with a net loss of $22.6 million
in fiscal 1998. These losses included special charges, including charges for
restructuring and personnel reductions related to cost-cutting measures we took
in response to the industry downturn. If we take cost-cutting measures in
response to another downturn in the semiconductor industry, we may be unable to
continue to invest in marketing, research, development and engineering at the
levels we think necessary to maintain our competitive position. Our failure to
make these investments could seriously curtail our long-term business prospects.

OUR LENGTHY SALES CYCLE MAKES IT DIFFICULT TO ANTICIPATE SALES.

Our systems often have a lengthy sales cycle. As a result, we have
difficulty anticipating the timing and amount of specific sales. We may also
spend significant amounts of money and effort with no assurance that we will
make a sale. Before buying one of our systems, a prospective customer must
generally decide to upgrade or expand existing facilities or to construct new
facilities. These undertakings are major decisions for most prospective
customers and typically involve significant capital commitments and lengthy
evaluation and approval processes. In addition, downturns in the semiconductor
industry may cause prospective customers to postpone decisions regarding major
capital expenditures, including purchases of our systems.

6
<PAGE>
OUR OPERATING RESULTS FLUCTUATE SIGNIFICANTLY, AND OUR STOCK PRICE COULD
FALL IF OUR OPERATING RESULTS ARE BELOW THE EXPECTATIONS OF ANALYSTS OR
INVESTORS.

Many factors may cause our operating results to fluctuate significantly.
Some of these factors are:

- the timing of significant orders;

- the gain or loss of any significant customer;

- new product announcements and releases by us or our competitors;

- order cancellations and shipment reschedulings or delays;

- patterns of capital spending by our customers;

- market acceptance of new and enhanced versions of our products;

- changes in the pricing and the mix of products we sell;

- cyclicality in the semiconductor industry and the markets served by our
customers;

- the timing of any acquisitions and related costs; and

- changes in personnel and related costs.

In addition, because our services and maintenance revenue is largely
correlated with our product and equipment revenue, a decline in product and
equipment revenue could reduce services and maintenance revenue in the same
quarter or in subsequent quarters.

If our operating results fall below the expectations of financial analysts
or investors, our stock price could fall. As a result of these factors and the
other factors described in this section, we believe that period-to-period
comparisons of our revenue and operating results are not necessarily meaningful.
You should not rely on these comparisons to predict our future performance.

DELAY IN OUR SHIPMENT OF A SINGLE SYSTEM COULD SUBSTANTIALLY DECREASE OUR
SALES FOR A PERIOD.

We derive a substantial portion of our revenue from the sale of a relatively
small number of our systems. The purchase price of our systems generally ranges
from $3.0 million to $15.0 million, and we usually take more than one or two
fiscal quarters to deliver our systems. As a result, any delay in the
recognition of revenue for a single system could harm our results for a given
accounting period. If we delay a shipment near the end of a fiscal period
because, for example, the customer reschedules or cancels its order or we
encounter unexpected manufacturing difficulties, our sales in that fiscal period
could fall significantly below the expectations of financial analysts and
investors. This could cause our stock price to fall.

NEW ACCOUNTING GUIDANCE COULD RESULT IN DELAYED RECOGNITION OF OUR REVENUES.

In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, entitled "Revenue Recognition in Financial
Statements." The bulletin sets forth the SEC's guidance in applying generally
accepted accounting principles to selected revenue recognition issues. We will
be required to apply the guidance in the bulletin in our financial statements
beginning in our first quarter of fiscal 2001. The effects of applying this
guidance with respect to our historical reported revenue will be reflected as a
cumulative effect adjustment in our statement of operations for the first
quarter of fiscal 2001. We have not completed our evaluation of the guidance in
the bulletin as it relates to our business, and therefore cannot yet assess the
likely impact of application of the guidance on our future results of
operations, or the magnitude of the cumulative effect adjustment, if any, that
may be required. In certain situations, application of the guidance discussed in
the bulletin could delay the recognition of revenue that might otherwise have
been recognized in earlier periods. As a result, our reported revenue could
fluctuate more widely among fiscal periods in the future, and reported

7
<PAGE>
revenue for a particular fiscal period might not meet expectations. A
significant cumulative effect adjustment or delay in recognition of revenue
resulting from application of the guidance in the bulletin, while not affecting
our cash flow, could adversely affect our results of operations in one or more
future periods, which could cause our stock price to fall.

WE TYPICALLY CHARGE A FIXED PRICE FOR A SYSTEM, WHICH LEAVES US VULNERABLE
TO COST OVERRUNS.

Our operating results also fluctuate because our gross margins vary. Our
gross margins vary for a number of reasons, including:

- the mix of products we sell;

- the average selling prices of products we sell;

- the costs to manufacture, market, service and support our new products and
enhancements;

- the costs to customize our systems; and

- our efforts to enter new markets.

We typically charge a fixed price for our systems. As a result, if the costs we
incur in performing a contract exceed our expectations, we generally cannot pass
those costs on to our customer.

WE HAVE SIGNIFICANT FIXED COSTS WHICH ARE NOT EASILY REDUCED DURING A
DOWNTURN.

We continue to invest in research and development, capital equipment and
extensive ongoing customer service and support capability worldwide. These
investments create significant fixed costs that we may be unable to reduce
rapidly if we do not meet our sales goals. Moreover, if we lack a significant
backlog of orders for an extended period of time, we may have difficulty
planning our future production and inventory levels, which could also cause
fluctuations in our operating results.

WE HAVE A LIMITED NUMBER OF CUSTOMERS, AND THE LOSS, CANCELLATION OR DELAY
OF ANY ORDER BY THESE CUSTOMERS COULD HARM OUR BUSINESS.

Historically, we have derived a significant portion of our revenue from a
limited number of customers. We expect this trend to continue for the
foreseeable future. The loss, cancellation or delay of any order by these
customers could significantly reduce our revenue and harm our reputation in the
industry. Sales to our top ten customers accounted for 67% of our total net
revenue in fiscal 1997, 60% in fiscal 1998 and 54% in fiscal 1999. One customer,
Intel, accounted for 32% of our total net revenue in fiscal 1997, 19% in fiscal
1998 and 21% in fiscal 1999. Our largest customers can change from year to year,
as some customers complete large semiconductor fabrication facilities and others
initiate new projects. Moreover, at least one of our significant customers has
adopted a policy of maintaining multiple vendors for the products it purchases.
This kind of policy could limit our ability to sell our products to our
customers.

WE DO NOT HAVE LONG-TERM PURCHASE AGREEMENTS WITH OUR CUSTOMERS, AND AS A
RESULT OUR CUSTOMERS COULD STOP PURCHASING OUR PRODUCTS AND SERVICES AT ANY
TIME.

None of our customers has any long-term obligation to continue to purchase
our products or services, and any customer could reduce or cease ordering our
products or services. Our failure to obtain large orders from new or existing
customers could seriously harm our business. We believe that sales to some of
our customers will decrease in the near future as they complete their current
purchases for new or expanded semiconductor fabrication facilities. In the past,
our customers have sometimes failed to place orders we expected or have delayed
or canceled delivery schedules as a result of changes in their requirements.
Because of the long sales cycle for our products, we may have difficulty in
quickly replacing orders that our customers cancel or reduce. When a customer
cancels an order, our sales contract generally allows us to recover only our
costs and a portion of our anticipated profits from the sale. Any order
deferrals or cancellations could seriously harm our business.

8
<PAGE>
DEMAND FOR LESS EXPENSIVE SEMICONDUCTORS IS INCREASING PRESSURE TO REDUCE
PRICES IN OUR INDUSTRY.

Semiconductors are increasingly being incorporated into less expensive
products, which limits the price that semiconductor manufacturers can charge for
semiconductors. As a result, semiconductor manufacturers face increasing
pressure to reduce their costs, which in turn creates pressure on semiconductor
equipment manufacturers, such as ourselves, to reduce the prices of their
products. We believe that over time this trend will lead to lower prices, which
would reduce our revenue and adversely affect our operating results.

INDUSTRY CONSOLIDATION AND OUTSOURCING OF THE MANUFACTURE OF SEMICONDUCTORS
TO FOUNDRIES COULD REDUCE THE NUMBER OF AVAILABLE CUSTOMERS.

The substantial expense of building or expanding a semiconductor fabrication
facility is leading increasing numbers of semiconductor companies to contract
with foundries, which manufacture semiconductors designed by others. As
manufacturing is shifted to foundries, the number of our potential customers
could decrease, which would increase our dependence on our remaining customers.
Recently, consolidation within the semiconductor manufacturing industry has
increased. If semiconductor manufacturing is consolidated into a small number of
foundries and other large companies, our failure to win any significant bid to
supply equipment to those customers could seriously harm our reputation and
materially and adversely affect our revenue and operating results.

OUR ONGOING INVESTMENTS IN THE ASIA-PACIFIC MARKET MAY NOT BE SUCCESSFUL.

We believe that our continued presence in the Asia-Pacific market will be
important to our long-term future financial performance. Accordingly, we expect
to continue to invest significant resources to increase our presence in the
Asia-Pacific market. Many of our Japanese competitors have longstanding
collaborative relationships with Japanese and other semiconductor manufacturers
in the Asia-Pacific region. Accordingly, we may be unable to increase sales in
the Asia-Pacific semiconductor market. This market, which includes South Korea,
Taiwan, Singapore, China and, most significantly, Japan, represents a
substantial percentage of worldwide semiconductor manufacturing capacity.

WE HAVE INVESTED HEAVILY IN 300MM WAFER TECHNOLOGY, WHICH IS BEING ADOPTED
MORE SLOWLY THAN EXPECTED, AND COMPETITION FOR EARLY 300MM ORDERS MAY BE
INTENSE.

We have invested, and are continuing to invest, substantial resources to
develop new systems and technologies to automate the processing of 300mm wafers.
However, the industry transition from the current, widely used 200mm
manufacturing technology to 300mm manufacturing technology is occurring more
slowly than expected, partly as a result of the recent period of reduced demand
for semiconductors. Although a small number of pilot projects are currently in
operation, no 300mm semiconductor fabrication facility is producing wafers in
commercial quantities. Any significant delay in the adoption of 300mm
manufacturing technology, or the failure of the industry to adopt 300mm
manufacturing technology, could significantly reduce our opportunities for
future growth. Moreover, continued delay in the transition to 300mm technology
could permit our competitors to introduce competing or superior 300mm products.
Manufacturers implementing factory automation in 300mm pilot projects may
initially seek to purchase systems from multiple vendors. Competition, including
price competition, for such early 300mm orders could be vigorous. A vendor whose
system is selected for an early 300mm pilot project may have, or be perceived to
have, an advantage in competing for future orders, and thus the award to a
competitor of one or more early 300mm orders could cause our stock price to
fall.

WE NEED MANAGERIAL AND TECHNICAL EMPLOYEES, WHO ARE DIFFICULT TO HIRE AND
RETAIN.

We need to hire additional management-level employees and substantial
numbers of employees with technical backgrounds for both our hardware and
software engineering and technical support staffs. The market for these
employees is becoming increasingly competitive, and we have occasionally

9
<PAGE>
experienced delays in hiring these personnel. Our failure or inability to
recruit, retain and train adequate numbers of qualified personnel on a timely
basis would adversely affect our ability to develop, manufacture, install and
support our systems.

WE MAY HAVE DIFFICULTY MANAGING GROWTH IN LIGHT OF FLUCTUATING DEMAND.

If the semiconductor industry grows, we may have to design and manufacture
our systems in larger volumes than we do now. If demand for our products
increases rapidly, we may have difficulty increasing our production capacity
while maintaining our standards of quality and reliability, and delivery times
for our systems may increase. In particular, it could be difficult for us to
rapidly recruit and train the substantial number of qualified engineering and
technical personnel who would be necessary to fulfill one or more large,
unanticipated orders. If we fail to meet a customer's delivery or performance
criteria, we could lose business from that customer, cause long-term damage to
our reputation and have higher warranty and service costs. Any of these results
could seriously harm our business. Further, if we are unable to expand our
existing manufacturing capacity to meet demand, a customer's placement of a
large order for the development and delivery of factory automation systems
during a particular period might deter other customers from placing similar
orders with us for the same period.

Our systems, procedures, controls and staffing may not be adequate to
support any rapid growth in our operations, if any. Our failure to respond
effectively to fluctuating demand for our products and to manage our future
growth, if any, could seriously harm our business.

OUR INTERNATIONAL OPERATIONS CREATE SPECIAL RISKS.

Our net export sales to customers outside North America accounted for 46.6%
of our total net revenue in fiscal 1997, 35.5% in fiscal 1998 and 32.4% in
fiscal 1999. We anticipate that international sales will continue to account for
a significant portion of our total net revenue for the foreseeable future. Our
plans to expand internationally may distract our attention from our domestic
operations and may absorb financial resources needed elsewhere. Our
international operations are subject to additional risks, including:

- unexpected changes in trading policies, regulatory requirements, exchange
rates, tariffs and other barriers;

- unstable political and economic environments;

- greater difficulties in collecting accounts receivable;

- difficulties in managing distributors or representatives;

- restrictions on exporting and importing technology;

- fewer protections for our intellectual property;

- longer sales cycles than with domestic customers;

- difficulties in staffing and managing foreign operations;

- restrictions on the repatriation of earnings; and

- potentially adverse tax consequences.

Although our international sales are primarily denominated in U.S. dollars,
changes in currency exchange rates could make it more difficult for us to
compete with foreign manufacturers on price. If our international sales increase
relative to our total revenue, these factors could have a more pronounced effect
on our operating results. In any event, any of these factors could cause serious
harm to our business.

10
<PAGE>
WE FACE SIGNIFICANT COMPETITION FROM OTHER AUTOMATION COMPANIES, WHICH MAY
LIMIT THE PRICES WE CAN CHARGE FOR OUR SYSTEMS AND MAY CAUSE US TO LOSE SALES.

Our factory automation division competes with Daifuku, Murata Machinery,
Shinko Electric and a number of other smaller foreign and domestic manufacturers
of automated machinery used in semiconductor fabrication facilities. Our tool
automation systems division competes with Genmark Automation, Asyst
Technologies, Brooks Automation and a number of other foreign and domestic
wafer-handling robotics companies, including in-house organizations of process
tool manufacturers that develop their own automation technology, as well as
other smaller robotics companies. Our software products compete with products
provided by Consilium, a subsidiary of Applied Materials, Brooks Automation and
other vendors. We believe that competition in our industry is likely to
intensify.

We believe that, once a semiconductor manufacturer selects a vendor's
equipment for a particular fab, the manufacturer may continue to rely upon that
equipment for a specific application in other fabs. Accordingly, we may have
difficulty selling to potential customers that have selected a competitor's
equipment, and we expect that difficulty to last for a significant period of
time. However, at least one of our significant customers has adopted a policy of
maintaining multiple vendors for the products it purchases. This kind of policy
could limit additional sales to existing customers. In addition, the expected
transition to 300mm technology may cause new competitors to enter our markets
and may diminish our competitive advantage with customers for whom we are the
incumbent supplier of automation equipment. In the face of increased
competition, we may need to lower our prices, which could seriously harm our
business.

WE MUST CONTINUALLY IMPROVE OUR TECHNOLOGY TO REMAIN COMPETITIVE.

Technology changes rapidly in the semiconductor manufacturing industry. Our
ability to compete will depend, in part, on our ability to develop and introduce
more advanced systems at competitive prices and on a cost-effective basis so as
to enable our customers to integrate them into their operations either before or
as they begin volume product manufacturing. For example, as the semiconductor
industry transitions from 200mm manufacturing technology to 300mm technology, we
believe it is important to our future success to develop and sell new products
that are compatible with 300mm manufacturing technology. If our competitors
introduce new technologies, our sales could decline and our existing products
could lose market acceptance. Our success in developing, introducing, selling
and supporting more advanced systems depends upon many factors, including:

- component selection;

- timely and efficient completion of product design and development;

- timely and efficient implementation of manufacturing and assembly
processes;

- software development;

- product performance in the field; and

- effective sales, marketing, service and project management.

Because we must commit resources to product development well in advance of
sales, our product development decisions must anticipate technological advances
by leading semiconductor manufacturers. We may not be successful in that effort.
Our inability to select, develop, manufacture and market new systems or enhance
our existing systems could cause us to lose our competitive position and could
seriously harm our business.

11
<PAGE>
WE MAY EXPERIENCE DELAYS IN PRODUCT DEVELOPMENT AND TECHNICAL DIFFICULTIES
THAT COULD DELAY NEW PRODUCT INTRODUCTIONS.

Because our systems are complex and have a large number of components, there
can be a significant lag between the time we introduce a system and the time we
begin to produce that system in volume. We have occasionally experienced delays
in introducing some of our systems and enhancements, as well as certain
technical and manufacturing difficulties with those systems and enhancements.
For example, as the level of sophistication of technology in the semiconductor
industry increases, we have found it increasingly difficult to coordinate
complex manufacturing equipment and software in our systems and to train our
technical and manufacturing personnel in a timely manner. We could experience
similar delays and difficulties in the future. In addition, we must customize
some of our systems to meet a customer's site or operating requirements. Our
inability to complete the development or meet the technical specifications of
any of our new systems or enhancements or to manufacture and ship these systems
or enhancements in volume in a timely manner could impair our relationships with
our customers and seriously harm our business. In addition, we may incur
substantial unanticipated costs to ensure that our new products function
properly and reliably early in their life cycle. These costs could include
greater than expected installation and support costs or increased materials
costs as a result of expedited changes. We may not be able to pass these costs
on to our customers. Any of these events could seriously harm our business.

FUTURE ACQUISITIONS MAY DISRUPT OUR OPERATIONS.

We acquired Promis Systems in March 1999, we acquired Equipe and its
European distributor, Chiptronix Handling Systems, in the first half of 1998 and
we acquired Interval Logic Corporation in 1997. We actively pursue potential
acquisitions, and any acquisition we make could disrupt our operations and
seriously harm our business. We may encounter difficulties in integrating the
operations of acquired companies with our own operations. We may also be unable
to successfully develop, market and sell their products. Any future acquisitions
also pose additional risks, including:

- diversion of our management's attention;

- loss of key employees of the acquired company;

- interruptions in the sales efforts of the acquired company;

- failure to integrate financial and accounting systems successfully;

- significant acquisition and integration expenses; and

- assumption of legal and other liabilities and risks.

Any of these factors could seriously harm our business. Moreover, these and
future acquisitions may not produce the revenue, earnings or business synergies
that we anticipated, and an acquired product, service or technology might not
perform as we expected. Any such event could cause customer dissatisfaction and
damage our reputation.

If we issue equity securities to pay for an acquisition, the ownership
percentage of our existing stockholders would be reduced. If we use cash to pay
for an acquisition, the payment could significantly reduce the cash that would
be available to fund our operations or for other purposes. Acquisition financing
may not be available on favorable terms, or at all. In addition, we may be
required to amortize significant amounts of goodwill or other intangible assets
in connection with future acquisitions, which could seriously harm our operating
results.

WE DEPEND ON SUBCONTRACTORS AND ONE OR A FEW SUPPLIERS FOR SOME COMPONENTS
AND MANUFACTURING PROCESSES.

For some components or specialized processes that we use in our products,
such as painting of system cabinets and enclosures, we depend on subcontractors
or have available only one or a few

12
<PAGE>
suppliers. Our reliance on subcontractors gives us less control over the
manufacturing process and exposes us to significant risks, especially inadequate
capacity, late delivery, substandard quality and high costs. We intend in the
near future to outsource additional aspects of our manufacturing operations to
additional subcontractors and suppliers. We could experience disruption in
obtaining components we need for our products and may not be able to develop
alternatives in a timely manner. If we are unable to obtain adequate deliveries
of components for our products for an extended period of time, we may have to
pay more for inventory, parts and other supplies, seek alternative sources of
supply or delay shipping products to our customers. We could also damage our
relationships with customers. Any such increased costs, delays in shipping or
damage to customer relationships could seriously harm our business.

WE DEPEND ON MORDECHAI WIESLER AND MITCHELL G. TYSON.

Our future success depends significantly on the skills, experience and
efforts of our founder, Chairman of the Board and Treasurer, Mordechai Wiesler,
and our President and Chief Executive Officer, Mitchell G. Tyson. We also depend
on other executive officers and key personnel. Many of these individuals would
be difficult to replace. The loss of Mr. Wiesler, Mr. Tyson or any other key
person could seriously harm our business.

OUR SOFTWARE PRODUCTS MAY CONTAIN ERRORS OR DEFECTS THAT COULD RESULT IN
LOST REVENUE, DELAYED OR LIMITED MARKET ACCEPTANCE OR PRODUCT LIABILITY CLAIMS
WITH SUBSTANTIAL LITIGATION COSTS.

Complex software products like ours can contain errors or defects,
particularly when we first introduce new products or when we release new
versions or enhancements. Defects or errors in current or future products,
including FAbuilder, PROMIS, TransNet and our recently announced Encore!
software, could result in lost revenue or a delay in market acceptance, which
would seriously harm our business and operating results. In the past, we have
occasionally discovered software errors in our new software products and new
releases after their introduction, and we expect that this will continue.
Despite internal testing and testing by current and potential customers, our
current and future products may contain serious defects.

Because many of our customers use our products for business-critical
applications, any errors, defects or other performance problems could result in
financial or other damage to our customers and could significantly impair their
operations. Our customers could seek to recover damages from us for losses
related to any of these issues. A product liability claim brought against us,
even if not successful, would likely be time consuming and costly to defend and
could adversely affect our marketing efforts.

WE MAY BE UNABLE TO PROTECT OUR PROPRIETARY TECHNOLOGY.

Our success depends to a significant degree upon our patent for certain key
elements of our AeroTrak monorail system, our other patents, our source code and
our other proprietary technology. The steps we have taken to protect our
technology may be inadequate. If so, we might not be able to prevent others from
using what we regard as our technology to compete with us. For example, our
patents could be challenged, invalidated or circumvented, and the rights we have
under our patents could provide no competitive advantages. Existing trade
secret, copyright and trademark laws offer only limited protection. In addition,
the laws of some foreign countries do not protect our proprietary technology to
the same extent as the laws of the United States. Other companies could
independently develop similar or superior technology without violating our
proprietary rights. Any misappropriation of our technology or the development of
competitive technology could seriously harm our business.

If we have to resort to legal proceedings to enforce our intellectual
property rights, the proceedings could be burdensome and expensive and could
involve a high degree of risk.

CLAIMS BY OTHERS THAT WE INFRINGE THEIR PROPRIETARY TECHNOLOGY COULD HARM
OUR BUSINESS.

Third parties could claim that our products or technology infringe their
patents or other proprietary rights. Although we conduct patent searches to
determine whether the technology used in

13
<PAGE>
our products infringes patents held by third parties, these searches are not
comprehensive and may not reveal potential third party claimants. Any claim of
infringement by a third party could cause us to incur substantial costs
defending against the claim, even if the claim is invalid, and could distract
our management from our business. Furthermore, a party making such a claim could
secure a judgment that requires us to pay substantial damages. A judgment could
also include an injunction or other court order that could prevent us from
selling our products. Any of these events could seriously harm our business.

If anyone asserts a claim against us relating to proprietary technology or
information, we might seek to license their intellectual property or to develop
non-infringing technology. We might not be able to obtain a license on
commercially reasonable terms or on any terms. Alternatively, our efforts to
develop non-infringing technology could be unsuccessful. Our failure to obtain
the necessary licenses or other rights or to develop non-infringing technology
could prevent us from selling our products and could therefore seriously harm
our business.

RISKS RELATED TO THIS OFFERING

THE MARKET PRICE OF OUR COMMON STOCK IS VOLATILE, WHICH COULD RESULT IN
SUBSTANTIAL LOSSES FOR INVESTORS PURCHASING SHARES IN THIS OFFERING.

The market price of our common stock has fluctuated widely and may continue
to do so. For example, during fiscal 1999 and the first two quarters of fiscal
2000 the price of our stock ranged from a high of $94.50 per share to a low of
$9.57 per share. Many factors could cause the market price of our common stock
to rise and fall. These factors include:

- variations in our quarterly operating results;

- announcements of technological innovations;

- introduction of new products or new pricing policies by us or our
competitors;

- announcements by us or our competitors of significant customer orders;

- acquisitions or strategic alliances by us or others in our industry;

- the hiring or departure of key personnel;

- changes in the semiconductor industry cycle;

- changes in market valuations of companies within the semiconductor
industry; and

- changes in estimates of our performance or recommendations by financial
analysts.

When the market price of a stock has been volatile, holders of that stock
have often instituted securities class action litigation against the company
that issued the stock. If any of our stockholders brought such a lawsuit against
us, we could incur substantial costs defending the lawsuit. The lawsuit could
also divert the time and attention of our management. Any of these events could
seriously harm our business.

WE MAY NEED ADDITIONAL FINANCING, WHICH COULD BE DIFFICULT TO OBTAIN.

We expect our existing cash and investment balances, funds available under
our revolving credit facility agreement and cash generated from operations,
together with our net proceeds from this offering, will be sufficient to meet
our cash requirements to fund operations and expected capital expenditures
during at least the next twelve months. After that, we may need to raise
additional funds and we cannot be certain that we will be able to obtain
additional financing on favorable terms, if at all. Further, if we issue
additional equity securities, stockholders may experience additional dilution or
the new equity securities may have rights, preferences or privileges senior to
those of existing holders of common stock. If we cannot raise funds on
acceptable terms, if and when needed, we may not be

14
<PAGE>
able to develop or enhance our products and services, take advantage of future
opportunities, grow our business or respond to competitive pressures or
unanticipated requirements, which could seriously harm our business.

PROVISIONS OF OUR CHARTER AND BY-LAWS AND MASSACHUSETTS LAW MAKE A TAKEOVER
OF OUR COMPANY MORE DIFFICULT.

Our basic corporate documents, our stockholder rights plan and Massachusetts
law contain provisions that could discourage, delay or prevent a change in the
control of our company, even if a change of control would be beneficial to our
stockholders.

WE CANNOT STATE WITH CERTAINTY HOW WE WILL USE THE PROCEEDS OF THIS
OFFERING.

We intend to use our net proceeds from the offering for general corporate
purposes, including working capital and possible acquisitions of and investments
in complementary businesses. We have not reserved or allocated the net proceeds
for any specific purpose, and we cannot state with certainty how we will use the
net proceeds. Accordingly, we will have considerable discretion in applying the
net proceeds. We may not be successful in investing the proceeds from this
offering, in our operations or external investments, to yield a favorable
return.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS AND INDUSTRY DATA

Some of the information in this prospectus and in the documents that we
incorporate by reference into this prospectus contains forward-looking
statements that involve substantial risks and uncertainties. You can identify
these statements by forward-looking words such as "expect," "anticipate,"
"plan," "believe," "seek," "estimate," "internal," "backlog" and similar words.
Statements that we make in this prospectus and in the documents that we
incorporate by reference into this prospectus that are not statements of
historical fact may also be forward-looking statements. In particular,
statements that we make in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" relating to our shipment level and
profitability, increased market share and the sufficiency of capital to meet
working capital and capital expenditures requirements, are forward-looking
statements. Forward-looking statements are not guarantees of our future
performance, and involve risks, uncertainties and assumptions that may cause our
actual results to differ materially from the expectations we describe in our
forward-looking statements. There may be events in the future that we are not
accurately able to predict, or over which we have no control. You should not
place undue reliance on forward-looking statements. We do not promise to notify
you if we learn that our assumptions or projections are wrong for any reason.
Before you invest in our common stock, you should be aware that the factors we
discuss in "Risk Factors" and elsewhere in this prospectus could cause our
actual results to differ from any forward-looking statements.

This prospectus contains industry data related to our business and the
semiconductor industry. This industry data includes projections that are based
on a number of assumptions. If these assumptions turn out to be incorrect,
actual results may differ from the projections based on these assumptions. The
failure of semiconductor manufacturers to buy wafer fabrication equipment at
expected rates may have a material adverse effect on our business, results of
operations and financial condition, and the market price of our common stock.

USE OF PROCEEDS

We estimate that our net proceeds from the sale of the 1,400,000 shares of
common stock we are offering, after deducting the underwriting discounts and
commissions and estimated offering expenses that we will pay, at the public
offering price of $64.00 per share, will be approximately $84.6 million, or
approximately $100.2 million if the underwriters exercise their over-allotment
option in full. We will not receive any proceeds from the sale of common stock
by the selling stockholders.

We intend to use our net proceeds from the offering for general corporate
purposes, including working capital and possible acquisitions of and investments
in complementary businesses. Accordingly, our management will have broad
discretion in the application of our net proceeds. We currently have no
agreement or understanding regarding any acquisition or investment. Pending
these uses, we intend to invest our net proceeds from the offering in
investment-grade, short-term, interest-bearing instruments.

DIVIDEND POLICY

We have never paid or declared cash dividends on our common stock and do not
anticipate paying cash dividends in the foreseeable future. The current policy
of our board of directors is to retain all earnings, if any, for use in our
business.

PRICE RANGE OF COMMON STOCK

Our common stock is traded on the Nasdaq National Market under the trading
symbol "PRIA." As of April 21, 2000, there were 299 holders of record of our

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

We are a leading global supplier of factory automation systems and factory
management software for semiconductor manufacturers and of automation systems
that are incorporated in semiconductor process tools manufactured by OEMs. We
entered the semiconductor manufacturing automation business in 1982, initially
concentrating on developing, manufacturing and selling tool automation systems.
In fiscal 1992, we installed our first interbay automation systems and in fiscal
1994 we introduced our first intrabay automation systems.

We have expanded our product offerings through a series of acquisitions. In
October 1997, we acquired Interval Logic Corporation, or ILC, a developer of
advanced planning and scheduling software for the semiconductor industry. In
January 1998, we acquired Equipe Technologies, a manufacturer of atmospheric and
vacuum wafer-handling robots, pre-aligners and controllers, and its affiliates
Equipe Japan and E-Machine, which we refer to as the Equipe Companies. In
May 1998, we acquired Chiptronix Handling Systems, Equipe's European
distributor. In March 1999, we acquired Promis Systems, a developer of
manufacturing execution system, or MES, software. We accounted for the Equipe
Companies, Chiptronix and Promis transactions using the pooling-of-interests
method of accounting. We have restated all of the financial statements presented
in this prospectus to include the financial position, results of operations and
cash flows of the Equipe Companies and Promis. We have not restated our
financial statements to reflect the acquisition of Chiptronix, because the
effect of that restatement would be immaterial.

Our business depends upon capital expenditures by semiconductor
manufacturers in response to demand for semiconductor products. The
semiconductor industry has been highly cyclical, and periods of oversupply in
the market for semiconductors have caused significantly reduced demand for
capital equipment, including systems such as ours. Periods of reduced demand for
semiconductor manufacturing equipment occurred in 1992 and again in 1996. The
semiconductor industry has only recently begun to recover from a protracted
worldwide downturn that began in 1998 and increased in severity during 1999,
exacerbated by economic instability in Asia. Our revenue decreased by
approximately 14% from fiscal 1997 to fiscal 1998, and by an additional 33% in
fiscal 1999. However, since the second quarter of fiscal 1999 we have
experienced four successive quarters of revenue growth, reflecting in part,
increased demand for semiconductor products and manufacturing equipment.

In addition to making the acquisitions described above, we have continued to
invest in new product development to maintain our technological and market
leadership, including enhancements of our 200mm product line, development of new
300mm products, and introduction of our new MES and planning and scheduling
software. Our research and development expenditures increased from
$36.2 million in fiscal 1997 to $44.5 million in fiscal 1998 and $45.5 million
in fiscal 1999. Meanwhile, we implemented layoffs and other expense reduction
measures in other areas of our business, to the extent that we could do so
without materially impairing our ability to meet customer requirements. In
fiscal 1998, we recorded restructuring and other special charges of
$5.6 million, reflecting personnel reductions, integration of the operations of
the Equipe Companies and disposition of excess facilities and assets. In fiscal
1999, we recorded charges of $2.4 million relating to additional personnel
reductions, restructuring and disposition of excess facilities. We have also
recorded special charges relating to our recent acquisitions. These include
merger costs of $4.5 million relating to our Equipe Companies acquisition in
fiscal 1998 and merger costs of $4.0 million relating to our acquisition of
Promis in fiscal 1999. We also recorded a charge of $8.4 million for acquired
in-process research and development relating to our acquisition of ILC in fiscal
1998. These charges, along with our continued investment in research and
development expenditures, contributed to our net losses of $22.6 million in
fiscal 1998 and $36.1 million in fiscal 1999.

Product and equipment net revenue includes revenue from all equipment sales,
installation, project management and software licenses. Service and maintenance
net revenue consists of service contracts, spare part sales, repairs and
upgrades, software maintenance contracts and consulting and training services.
Our revenue recognition depends on the particular product or service provided.
For certain contracts eligible under American Institute of Certified Public
Accountants Statement of Position No. 81-1, we recognize revenue on product
sales using the percentage-of-completion accounting method based upon an
efforts-expended method. We recognize changes to total estimated costs and
anticipated losses, if any, in the period in which they are determined. Revenue
recognized under the percentage-of-completion accounting method was
approximately $100.7 million in fiscal 1997, $55.0 million in fiscal 1998 and
$23.4 million in fiscal 1999. Revenue from product sales that we do not
recognize under the percentage-of-completion method is generally recorded upon
shipment to the customer, provided that no significant vendor obligations remain
outstanding and that we deem collection of the related receivable to be
probable. We recognize software license revenue upon delivery of the software
and receipt of a written agreement from the customer, provided that acceptance
is not uncertain, fees are fixed and determinable and we deem collection of the
related receivable to be probable. We recognize revenue from training and
consulting as services are performed. We recognize service revenue ratably over
applicable contract periods or as the services are performed. We accrue for
warranty costs upon shipment.

Historically, a significant portion of our net revenue in any particular
period has been attributable to sales to a limited number of customers. Net
revenue from our largest customer accounted for 32% of our total net revenue in
fiscal 1997, 19% in fiscal 1998 and 21% in fiscal 1999. Our largest customers
may also change from year to year, as large fab projects are completed and new
projects are initiated.

THREE MONTHS ENDED JANUARY 2, 2000 VERSUS THREE MONTHS ENDED DECEMBER 27, 1998

TOTAL NET REVENUE: Total net revenue for the fiscal quarter ended
January 2, 2000 increased 98.1% to $58.7 million, compared to $29.6 million for
the corresponding period in fiscal 1999. This represents the fourth consecutive
quarter of revenue growth. The growth was experienced across all of our
operating segments. Most of the increase was related to product and equipment
revenue, which increased 137.3%, while services and maintenance revenue
increased 6.9% from the corresponding period in fiscal 1999. The increase in net
revenue is due to the growth in requirements for capital equipment within the
semiconductor industry arising from the increase in demand for semiconductor-
related products. Net export sales to European and Asian customers for the
fiscal quarter ended January 2, 2000 were $24.8 million, or 42.3% of total net
revenue, compared to $5.9 million, or 20.0% of total net revenue for the
corresponding period in fiscal 1999. Sales to foreign customers are denominated
in U.S. dollars with the exception of certain sales of tool automation and spare
parts products which are denominated in local currencies.

GROSS PROFIT: Our gross profit margin was 36.4% for the fiscal quarter
ended January 2, 2000, compared to 32.0% for the corresponding period in fiscal
1999. The increase in gross profit margin was primarily experienced by the
Factory Systems and Tool Automation Systems segments. The increase in the gross
profit margin is due to a number of factors including a change in product mix
with a more significant increase in product and equipment revenue as compared to
service and maintenance revenue. Additionally, the upturn in industry demand has
improved product pricing and the growth in production volume has increased
manufacturing efficiencies and improved related costs. At the same

23
<PAGE>
time, the gross profit margin was adversely impacted by costs related to the
introduction of new products.

RESEARCH AND DEVELOPMENT: Research and development expenses increased to
$12.2 million, or 20.7% of total net revenue, for the fiscal quarter ended
January 2, 2000, compared to $10.4 million, or 35.1% of total net revenue, for
the corresponding quarter in fiscal 1999. The increase in spending reflects our
continued investment in new product development and enhancements of existing
product lines. We continued to invest in the development of 200mm and 300mm
products throughout our factory automation and tool automation product lines, as
well as the manufacturing execution and advanced planning and scheduling
software product lines. Research and development expenses decreased as a
percentage of total net revenue for the fiscal quarter ended January 2, 2000,
compared with the corresponding period in fiscal 1999, due to the increase in
revenues.

SELLING, GENERAL AND ADMINISTRATIVE: Selling, general and administrative
expenses decreased to $9.0 million, or 15.4% of total net revenue, for the
fiscal quarter ended January 2, 2000, compared to $9.7 million, or 32.7% of
total net revenue, for the corresponding period in fiscal 1999. The decrease in
the dollar amount of selling, general and administrative expenses for the first
quarter of fiscal 2000 is primarily attributable to the consolidation of
duplicate functions and activities of acquired companies.

SPECIAL CHARGES: We did not incur special charges for the fiscal quarter
ended January 2, 2000. However, at January 2, 2000, $272,000 of previously
incurred special charges remained in accrued expenses. During the quarter ended
March 28, 1999, we recorded special charges of $1.9 million. The special charges
consisted of $1.4 million for compensation-related costs for five management
employees in the selling, general and administrative functions to satisfy
existing contractual obligations related to the acquired companies; $196,000 of
costs associated with the reductions of leased facilities; and $248,000 for
other legal issues. The remaining $272,000 of these special charges are expected
to be paid by the end of calendar year 2000.

During the first fiscal quarter of 1999, we recorded special charges of
$650,000 representing provisions for employee severance compensation relating to
the termination of 62 employees and consultants. The headcount reductions
included 40 in manufacturing and customer support, eight in engineering, and 14
in selling, general and administrative functions. The reduction in force
occurred in response to the downturn in the semiconductor equipment industry.
All of these special charges have been paid.

OPERATING PROFIT (LOSS): As a result of the increase in total net revenue
and the other foregoing factors, the operating profit for the fiscal quarter
ended January 2, 2000 was $204,000, or 0.3% of total net revenue, compared to an
operating loss of $11.3 million, or 38.0% of total net revenue, for the
corresponding quarter in fiscal 1999. Excluding the special charges of $650,000,
the operating loss in the first fiscal quarter of 1999 would have been $10.6
million, or 35.8% of net revenue.

OTHER INCOME, NET: Other income, net for the fiscal quarter ended January
2, 2000 was $200,000, compared to $656,000 for the corresponding quarter in
fiscal year 1999. Interest income for the fiscal quarter ended January 2, 2000
was $537,000, compared to $548,000 for the corresponding quarter in fiscal 1999.
Interest expense for the current quarter was $20,000, compared to $32,000 for
the prior quarter in fiscal 1999. Net translation and foreign exchange losses
for the current fiscal quarter was $241,000, compared to net translation and
foreign exchange gains of $198,000 in the corresponding quarter in fiscal 1999.

PROVISION FOR (BENEFIT FROM) INCOME TAXES: The income tax provision for the
three months ended January 2, 2000 was $110,000, or 27.2% of income before
income taxes, compared to a benefit of $2.9 million, or 27.8% of loss before
income taxes, for the three months ended December 27, 1998. The tax provision of
$110,000 is primarily related to foreign and state taxes. During the third
quarter of fiscal

24
<PAGE>
year 1999, management concluded that a full valuation allowance against our net
deferred tax assets was required, under applicable accounting standards, due to
uncertainties surrounding their realization. Accordingly a valuation allowance
in an amount equal to the net deferred tax assets was established to reflect
these uncertainties. The effective tax rate for the three months ended
December 27, 1998 differed from the statutory rate primarily because income of
certain foreign subsidiaries was not subject to income tax due to available tax
credits and net operating losses.

NET INCOME (LOSS): Net income for the fiscal quarter ended January 2, 2000
was $294,000, compared to the net loss of $7.7 million for the corresponding
quarter in fiscal 1999. Excluding the special charges net of their tax effect,
the net loss for the first quarter of fiscal 1999 would have been $7.2 million.

FISCAL 1999 VERSUS FISCAL 1998

TOTAL NET REVENUE: Total net revenue for fiscal 1999 decreased 33.0% to
$136.3 million, compared to $203.5 million for fiscal 1998. This overall
decrease in our total net revenue is attributable to the downturn in the
worldwide semiconductor industry, which resulted in a significant slowdown in
the construction or expansion of semiconductor fabs. The total net revenue
decline occurred primarily in our factory automation systems segment, which
declined by 34.7% in fiscal 1999, and in our tool automation systems segment,
which declined by 41.1% in fiscal 1999. While product and equipment revenue
decreased, we gained market share in fiscal 1999 and experienced a 14.1%
increase in our services and maintenance revenue. Net export sales to customers
outside North America were $44.2 million, or 32.4% of total net revenue, for
fiscal 1999, compared to $72.2 million, or 35.5% of total net revenue, for the
prior fiscal year.

GROSS PROFIT: Our gross profit margin was 38.5% for fiscal 1999, compared
to 38.7% for the prior fiscal year. In fiscal 1998, we had $14.0 million in
charges to product and equipment cost of revenue related to inventory and
warranty provisions. Excluding these charges, our fiscal 1998 gross profit
margin would have been 45.6%. The decline in gross profit margin in fiscal 1999
occurred principally in our factory automation systems segment, which decreased
to 20.4% from 23.7%. The deterioration in margin was the result of fixed
capacity and related manufacturing costs, which could not be reduced
proportionally with the reduction in production volume, and a decline in product
pricing for competitive reasons during the industry downturn. This decline was
partially offset by favorable changes in product mix. Our gross profit margin
for services and maintenance revenue increased in fiscal 1999 to 45.0% from
38.9% in fiscal 1998 and was primarily related to increased growth in software
maintenance contracts.

RESEARCH AND DEVELOPMENT: Research and development expenses increased
slightly to $45.5 million, or 33.3% of total net revenue, for fiscal 1999,
compared to $44.5 million, or 21.9% of total net revenue, for the prior fiscal
year. The increase in the dollar amount of research and development spending
reflects our continued investment in new product development and enhancements of
existing product lines. We continued to invest in the development of 200mm and
300mm products throughout our factory automation and tool automation product
lines as well as our manufacturing execution and advanced planning and
scheduling software product lines. We believe that these investments are
critical to maintaining and improving our technological and market leadership.

SELLING, GENERAL AND ADMINISTRATIVE: Selling, general and administrative
expenses decreased to $38.6 million, or 28.3% of total net revenue, for fiscal
1999, compared to $46.8 million, or 23.0% of total net revenue, for the prior
fiscal year. We reduced our expenses in fiscal 1999 in response to the industry
downturn and through the consolidation of common activities and functions of
acquired companies. In 1999, we reduced our work force by 62 persons, including
14 in sales, general and administrative functions, in addition to a reduction in
force of 244 persons, including 56 in sales,

25
<PAGE>
general and administrative functions, in 1998. See "--Merger costs and special
charges" for a discussion of severance and reductions of leased facilities.

ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT: In fiscal 1998, we recorded a
charge of $8.4 million in relation to the purchase of incomplete technology
acquired in the ILC acquisition.

MERGER COSTS AND SPECIAL CHARGES: During fiscal 1999, we incurred several
special charges. In the first quarter of fiscal 1999, we recorded special
charges of $650,000 representing provisions for severance compensation relating
to the termination of 62 persons. The personnel reductions included 40 in
manufacturing and customer support, eight in engineering and 14 in sales,
general and administrative functions. In the second quarter of fiscal 1999, we
acquired Promis in a pooling-of-interests transaction and recorded merger costs
of $4.0 million, consisting primarily of investment banking, legal and
accounting fees. In addition, during the second quarter, we recorded special
charges of $1.9 million. The special charges consisted of $1.4 million for
compensation-related costs for five management persons in sales, general and
administrative functions to satisfy existing contractual obligations related to
acquired companies; $196,000 of costs associated with the reduction of leased
facilities; and $248,000 for other legal costs. In the fourth quarter of fiscal
1999, we recognized a credit of $75,000 to adjust the estimated costs to reflect
actual costs. At September 30, 1999, $424,000 of these charges remained in
accrued expenses and are expected to be paid by December 2000.

During fiscal 1998, we incurred several special charges. In the second
quarter of fiscal 1998, we acquired the Equipe Companies in a transaction
accounted for as a pooling-of-interests. Direct acquisition costs, primarily
related to legal, investment banking and accounting fees, amounted to
$4.5 million and were charged against the results of operations in the quarter.
Additionally, during the second, third and fourth quarters of fiscal 1998, we
recorded restructuring and other special charges of $5.6 million in response to
market conditions and to integrate the Equipe operations. The special charges
included provisions for severance compensation of $1.9 million resulting from
terminations of approximately 244 persons completed in 1998. The personnel
reductions consisted of 123 in manufacturing and customer support, 65 in
engineering and 56 in sales, general and administrative functions. In addition,
the special charges included costs of $2.9 million relating to reductions of
leased facilities space and a non-cash write-down of specialized demonstration
equipment for a particular customer of $748,000 and of other assets that are not
usable elsewhere. Of the total of $4.9 million in severance and lease reduction
charges recorded in fiscal 1998, all of these special charges had been paid as
of September 30, 1999.

OPERATING PROFIT (LOSS): As a result of the decline in revenue and the
other foregoing factors, for fiscal 1999 we experienced an operating loss of
$38.0 million, or negative 27.8% of total net revenue, compared to an operating
loss of $31.0 million, or negative 15.2% of total net revenue, for the prior
fiscal year.

OTHER INCOME, NET: Other income, net, in fiscal 1999 was $2.9 million, or
2.1% of total net revenue, compared to $625,000, or 0.3% of total net revenue,
for the prior fiscal year. Interest income was $2.2 million for fiscal 1999 and
$2.0 million for fiscal 1998, and interest expense was $123,000 for fiscal 1999
and $137,000 for fiscal 1998. Net translation and foreign exchange gains of
$854,000 were recorded in fiscal 1999, and net translation and foreign exchange
losses of $1.1 million were incurred in fiscal 1998.

PROVISION FOR (BENEFIT FROM) INCOME TAXES: The income tax provision for
fiscal 1999 was $1.1 million, compared to a benefit of $7.8 million for the
previous fiscal year. The effective tax rate in fiscal 1999 was 3.0% as compared
to a 25.6% benefit for the previous fiscal year. In fiscal 1999, the effective
tax rate was unfavorably affected by the provision for foreign taxes and the
increase in the valuation allowance as a result of management's conclusion that
a full valuation allowance against our

26
<PAGE>
net deferred tax asset was required, under applicable accounting criteria. The
effect of the provision for foreign taxes and the increase in the valuation
allowance was partially offset by our ability to carry back tax losses generated
in fiscal 1999 to a prior profitable period. The fiscal 1998 effective tax
benefit was unfavorably affected by the fact that charges for acquired
in-process research and development and merger and other special charges were
not fully deductible for income tax purposes. This unfavorable impact was
partially offset by the effect of the acquisition of Equipe Technologies and
E-Machine, which were both subchapter S-corporations for federal income tax
purposes for the three months ended December 28, 1997.

FISCAL 1998 VERSUS FISCAL 1997

TOTAL NET REVENUE: Total net revenue for fiscal 1998 decreased 13.8% to
$203.5 million, compared to $236.1 million for fiscal 1997. This decrease is
attributable to the downturn in the worldwide semiconductor industry which began
in fiscal 1998 and which resulted in a significant slowdown in the construction
and expansion of semiconductor fabs. The decline in total net revenue in fiscal
1998 occurred in our factory automation systems segment, which declined by
36.7%. This decline was partially offset by an increase in our tool automation
systems segment of 61.3% and an increase in our MES and other systems segment of
12.8%. Our services and maintenance revenue grew by 70.1% in fiscal 1998 while
product and equipment revenue declined by 21.0%. Net export sales outside North
America were $72.2 million, or 35.5% of total net revenue, for fiscal 1998,
compared to $110.1 million, or 46.6% of total net revenue, for fiscal 1997.

GROSS PROFIT: Our gross profit margin decreased to 38.7% for fiscal 1998,
compared to 48.8% for fiscal 1997. In fiscal 1998, there were $14.0 million in
charges to product and equipment cost of revenue related to inventory and
warranty provisions. Excluding these charges, our fiscal 1998 gross profit
margin would have been 45.6%. The decrease in gross margin is attributable to
the industry downturn during which fixed capacity and the related manufacturing
costs could not be reduced proportionally with the decline in production volume,
and to declines in product pricing for competitive reasons. The decline in gross
profit margin in fiscal 1998 was principally in our factory automation systems
segment, which declined to 23.7% from 43.6% in the prior year. The tool
automation systems segment's gross profit margin declined in fiscal 1998 to
43.6% from 48.2% in fiscal 1997, while the MES and other systems segment's gross
margin remained flat.

RESEARCH AND DEVELOPMENT: Research and development expenses increased to
$44.5 million, or 21.9% of total net revenue, for fiscal 1998, compared to
$36.2 million, or 15.3% of total net revenue, for the prior fiscal year. The
increase in dollar amount reflects our investment in new product development and
enhancement to existing products. We continued to invest in the development of
200mm and 300mm products throughout the factory automation and tool automation
product lines, as well as our manufacturing execution, advanced planning and
scheduling software products.

SELLING, GENERAL AND ADMINISTRATIVE: Selling, general and administrative
expenses increased to $46.8 million, or 23.0% of total net revenue, for fiscal
1998, compared to $43.6 million, or 18.5% of total net revenue, for the prior
fiscal year. The increase in dollar amount primarily reflects the increase in
personnel and related expenses associated with expansion in late fiscal 1997 and
early fiscal 1998 of our marketing, market research and communications programs
and increased sales and marketing efforts worldwide. See "--Merger costs and
special charges" for a discussion of severance and reductions of leased
facilities.

ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT: On October 29, 1997, we
acquired ILC for aggregate consideration of 111,258 shares of our common stock.
In addition, we issued or assumed options to purchase an aggregate of 199,170
shares of our common stock. ILC was formed in 1995 to develop advanced,
high-performance planning and scheduling software solutions for the
semiconductor

27
<PAGE>
industry. The value of the transaction was $8.5 million, including approximately
$600,000 of expenses related to the acquisition. The transaction was accounted
for as a purchase.

At the time of the acquisition, the purchase price was allocated to the
tangible and intangible assets of ILC. Our management is responsible for
estimating the fair value of purchased in-process research and development. The
value assigned to the intangible assets, primarily the acquired technology, was
based on the fair market value using a risk-adjusted discounted cash flow
approach. ILC's sole product at the time of the acquisition was the Leverage
product, which was under development. ILC had no product revenues during its
prior existence and was a development stage enterprise. The total development
effort was estimated to take approximately 225 engineering man-months at a cost
of approximately $2.8 million. The project included completion of the software
requirement definition, data integration, and validation, completion of the
graphics user interface, development of alpha and beta versions for customer
testing, and integration and adaptation with customer systems. The significant
further investments in development required to meet expected customer
requirements were substantially completed in the third quarter of fiscal 1999.
The actual development costs have approximated the cost estimates used in the
valuation model.

The acquired technology had not reached technological feasibility at the
time of the acquisition. We define technological feasibility as the point at
which a working model is functioning to designed specification and has been
placed at a beta test site. The Leverage product was first released to a beta
test site in March 1999. In addition, the technology had no alternative future
use to us in other research and development projects or otherwise. Accordingly,
the acquired technology was expensed as in-process research and development.
Based on the methodology described above, we assigned a fair value of
$8.4 million to the technology.

MERGER COSTS AND SPECIAL CHARGES: During fiscal 1998, we incurred several
special charges. In the second quarter of fiscal 1998, we acquired the Equipe
Companies in a transaction accounted for as a pooling-of-interests. Direct
acquisition costs, primarily related to legal, investment banking and accounting
fees, amounted to $4.5 million and were charged against the results of
operations in the quarter. Additionally, during the second, third and fourth
quarters of fiscal 1998, we recorded restructuring and other special charges of
$5.6 million in response to market conditions and to integrate the Equipe
operations. The special charges included provisions for severance compensation
of $1.9 million resulting from terminations of approximately 244 persons
completed in 1998. The personnel reductions consisted of 123 in manufacturing
and customer support, 65 in engineering and 56 in sales, general and
administrative functions. In addition, the special charges included costs of
$2.9 million relating to reductions of leased facilities space and a non-cash
write-down of specialized demonstration equipment for a particular customer of
$748,000 and of other assets that are not usable elsewhere. Of the total of
$4.9 million in severance and lease reduction charges recorded in fiscal 1998,
all of these special charges had been paid as of September 30, 1999.

OPERATING PROFIT (LOSS): As a result of the foregoing factors, our
operating loss for fiscal 1998 was $31.0 million, or negative 15.2% of total net
revenue, compared to an operating profit of $35.3 million, or 15.0% of total net
revenue, for the prior fiscal year.

OTHER INCOME, NET: Other income, net, in fiscal 1998 decreased to $625,000,
or 0.3% of total net revenue, compared to $1.2 million, or 0.5% of total net
revenue, for the prior fiscal year. Interest income was $2.0 million for fiscal
1998 and $1.5 million for fiscal 1997, and interest expense was $137,000 for
fiscal 1998 and $116,000 for fiscal 1997. Net translation and foreign exchange
losses were $1.1 million in fiscal 1998 and $520,000 in fiscal 1997.

PROVISION FOR (BENEFIT FROM) INCOME TAXES: The income tax benefit for
fiscal 1998 was $7.8 million, compared to a provision of $9.0 million for the
previous fiscal year. The effective tax rate in fiscal 1998 was a 25.6% benefit,
compared to a 24.7% provision in the previous fiscal year. The effective tax

28
<PAGE>
benefit for fiscal 1998 was unfavorably affected by the fact that charges for
acquired in-process research and development and merger and other special
charges were not fully deductible for income tax purposes. This unfavorable
impact was partially offset by the effect of the acquisition of Equipe
Technologies and E-Machine, which were both subchapter S-corporations for
federal income tax purposes for the three months ended December 28, 1997. The
fiscal 1997 effective tax rate reflects the fact that Equipe Technologies and
E-Machine were not subject to federal income taxes before the acquisition due to
S-corporation status.

LIQUIDITY AND CAPITAL RESOURCES

We have funded our operations primarily through public stock offerings in
October 1994 and July 1995, cash generated from operations and bank lines of
credit. As of January 2, 2000, we had working capital of $87.3 million,
including cash and cash equivalents of $45.2 million, compared to working
capital of $78.9 million and cash and cash equivalents of $51.9 million as of
September 30, 1999.

Net cash used in operating activities was $11.8 million for the three months
ended January 2, 2000, compared to $6.7 million for the corresponding period in
fiscal 1999. The net cash used in operations in the first quarter of fiscal 2000
was primarily attributable to increases in contracts in progress of $11.8
million and increases in accounts receivable of $6.0 million. These increases
are related to the significant growth in total net revenue in the first quarter
of fiscal 2000. These cash outflows were slightly offset by proceeds associated
with the decrease in other assets, which is primarily the result of a $5.0
million income tax refund received in the first quarter of fiscal 2000. Net cash
used in operations for the three months ended December 27, 1998 was primarily
attributable to the $7.7 million net loss. Additionally, a decrease in accounts
payable used $5.1 million of net cash. This outflow was partially offset by
proceeds related to decreases in inventories of $4.7 million and increases in
accrued expenses of $1.9 million.

Net cash used in investing activities was $2.4 million for the three months
ended January 2, 2000, compared to $1.4 million for the corresponding period in
fiscal 1999. The increase in investing activities is primarily due to an
additional $1.2 million of property and equipment purchases made in the first
quarter of fiscal 2000 as compared with the corresponding period in fiscal 1999.

Net cash provided by financing activities was $7.9 million for the three
months ended January 2, 2000, compared to $825,000 for the corresponding period
in fiscal 1999. The net cash provided by financing activities for each of these
fiscal periods was primarily attributable to proceeds from the exercise of stock
options and our employee stock purchase plan.

At January 2, 2000, we had a revolving credit facility agreement with Chase
Manhattan Bank (the "Bank"). The revolving credit agreement expires on June 16,
2000. The revolving credit facility enables us to borrow up to $20,000,000 on an
unsecured basis. Outstanding revolving credit loans bear interest, at our
option, at the 30-, 60- or 90-day LIBOR rate plus a credit spread or at the
effective prime rate. At January 2, 2000, our borrowing rate would have been
7.0%. We had outstanding letters of credit with the Bank in the aggregate amount
of $1.4 million at January 2, 2000, and therefore, the available balance under
this credit agreement was $18.6 million at that date. Our ability to borrow
under the revolving credit facility is conditioned upon meeting certain
financial criteria. At January 2, 2000, we were not in compliance with the
minimum consolidated net worth requirement, the minimum fixed charge coverage
ratio and the minimum consolidated net income requirements of the revolving
credit agreement for the fiscal quarter ended January 2, 2000. On January 25,
2000, we obtained a waiver from the Bank of these defaults as of January 2,
2000. We will seek future waivers as necessary from the Bank. However, there can
be no assurance that such waivers will be obtained.

We believe our existing cash balances and funds available under its existing
revolving credit facility will be sufficient to meet our cash requirements to
fund operations and expected capital expenditures

29

during the next twelve months. However, there can be no assurance that
additional financing, if needed, will be available or at terms acceptable to us.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards, or SFAS, No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments, including some derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. The statement requires companies to
recognize all derivatives as either assets or liabilities, with the instruments
measured at fair value. The accounting for changes in fair value, gains or
losses depends on the intended use of the derivative and its resulting
designation. The statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 2000. We will adopt SFAS No. 133 by fiscal 2001, in
accordance with SFAS No. 137, which deferred the effective date of SFAS
No. 133. We are evaluating SFAS No. 133 to determine the impact on our
consolidated financial statements.

In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB
101"). SAB 101 summarizes the SEC staff's view in applying generally accepted
accounting principles to selected revenue recognition issues. The application of
the guidance in SAB 101 will be required in our first quarter of fiscal 2001.
The effects of applying this guidance will be reported as a cumulative effect
adjustment resulting from a change in accounting principle. The Company has not
completed its evaluation of SAB 101 and is therefore unable to determine its
impact.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

FOREIGN CURRENCY AND EXCHANGE RATE RISK

We conduct a portion of our business outside the United States through our
foreign subsidiaries. We have foreign currency exposure related to our
operations in international markets, where we transact some business in foreign
currencies, and accordingly we are exposed to adverse movements in foreign
currency exchange rates. Our foreign subsidiaries maintain their accounting
records in their local currencies. Consequently, changes in currency exchange
rates may affect the translation of foreign statements of operations into U.S.
dollars, which may in turn affect our consolidated statement of operations. Our
functional currency is the U.S. dollar for all of our subsidiaries, and
therefore, translation gains and losses are included as a component of net
income or loss. Substantially all of our revenue is invoiced and collected in
U.S. dollars.

During fiscal 1999, we entered into forward contracts in Canadian dollars to
hedge the expected operating expenses of our Canadian subsidiary, which are
denominated in Canadian dollars. These contracts were used to mitigate our risk
associated with exchange rate movements, as gains and losses on these contracts
were intended to offset exchange losses and gains on underlying cost exposures.
These contracts, for which the contract periods did not exceed sixteen months,
expired in December 1999, and we do not expect to renew them as part of our risk
management strategies. Realized and unrealized gains and losses on these
contracts, which did not qualify for hedge accounting, are classified in other
income, net.

At September 30, 1999, the notional amount of outstanding forward currency
contracts for Canadian dollars was $1.9 million, which was marked to market and
recognized in our consolidated statement of operations. The potential fair value
loss for a hypothetical 10% adverse change in Canadian currency exchange rates
at September 30, 1999 would be $186,000. The potential loss was estimated
calculating the fair value of the forward exchange contracts at September 30,
1999, and comparing that with the value calculated using the hypothetical
forward currency exchange rates.

We are a leading global supplier of advanced automation systems and software
for the semiconductor industry. We offer complete and flexible solutions that
address a wide range of automation requirements for semiconductor manufacturers
and for OEM manufacturers of semiconductor process tools. Our factory automation
systems and software help semiconductor manufacturers optimize the flow of
material and data throughout the fab, improving productivity and increasing the
manufacturer's return on investment. Our robotic wafer-handling systems and
software offer high-performance and reliability for OEM process tool
manufacturers, allowing them to focus on developing next generation process
technology. We also provide automation services, including equipment layout and
design, fab simulation, project management, installation and on-site support. We
sell and support our products through a global direct sales and support
organization operating out of offices in North America, Europe, Israel, Taiwan,
South Korea, Singapore, and Japan. Our customers include many of the world's
leading semiconductor manufacturers and semiconductor capital equipment
suppliers.

INDUSTRY BACKGROUND

The semiconductor industry has grown significantly during the past
15 years, driven by the demand for consumer electronic products, personal
computers, wireless communications devices and business computing products, and,
more recently, by the growth of the Internet. New products and technologies
typically require greater semiconductor content than previous generations. This
trend, combined with the increasing range of functions performed by integrated
circuits, drives semiconductor manufacturers to produce ever-greater quantities
of more complex, powerful integrated circuits as well as less expensive,
application-specific integrated circuits.

To meet the demand for greater volumes of increasingly complex semiconductor
devices, semiconductor manufacturers are currently making, and are expected to
continue to make, significant investments in manufacturing capacity through the
construction of new wafer facilities and the upgrade of existing wafer
facilities. As the complexity of advanced semiconductor devices has increased,
the cost of building or upgrading these facilities has also grown, and the cost
of constructing and equipping a state-of-the-art production fab today is in
excess of $1.5 billion. Dataquest, an independent research group, has estimated
that in 1999, semiconductor manufacturers spent $17.5 billion worldwide on wafer
fabrication equipment, and that this spending will grow to $38.3 billion in
2002.

Semiconductor production is one of the most complex and logistically
challenging manufacturing operations in the world. A silicon wafer, upon which
integrated circuits are manufactured, can travel approximately ten miles and
undergo 400-500 individual process steps as it moves throughout the fab during
its 30 to 45 day manufacturing cycle. State-of-the-art fabs produce from 10,000
to over 30,000 wafers a month and run 24 hours a day, seven days a week. As
semiconductor technology has advanced, the complexity of the manufacturing
process and the number of process tools and steps required have increased
correspondingly. As a result, managing the efficient flow of materials through
the facility has become an increasingly difficult task. At the same time,
semiconductor manufacturers have had to respond to the accelerating rate of
change in their markets, and to accommodate their customers' shorter product
development cycles, faster time-to-market requirements, more frequent changes in
product mix and delivery schedules and intensifying price competition.

The semiconductor industry is currently preparing for a transition to 300mm
wafer manufacturing that we expect will take place over the next two to five
years. This expected transition to 300mm wafer manufacturing will increase the
challenges described above and add to them the unique ergonomic and logistical
problems associated with handling, transporting and storing larger and heavier
300mm wafers.

31
<PAGE>
Advances in semiconductor technology, intensifying competitive pressures and
the need to improve the return on invested capital are driving semiconductor
manufacturers to seek ways to:

- increase wafer throughput while maintaining high product yields;

- lower production costs by maximizing utilization of facilities and process
tools;

- more efficiently manage the increasingly complex production process;

- respond more quickly and flexibly to changing customer requirements; and

- solve the ergonomic and logistical problems associated with 300mm
manufacturing.

Adoption of 300mm manufacturing technology is likely to accelerate the trend
towards increased automation. Two key industry standard-setting bodies have
stated that production of 300mm wafers in commercial quantities will require
factory-wide automation of wafer handling, transport and storage, including
enhanced automation within individual process bays.

Manufacturers seeking to implement broader factory automation strategies
have encountered a variety of challenges. To design, install and successfully
operate systems that involve numerous process tools, automation systems and
controls is a difficult task, which is only made more difficult if the
manufacturer must coordinate the efforts of multiple vendors, none of which has
overall responsibility for the design, manufacture or support of the entire
factory automation system. Manufacturers have also come to understand that the
efficient flow of data is as important as the movement of materials, and that to
extract maximum productivity and flexibility from the fab requires the ability
to capture, analyze and quickly act upon massive volumes of data from multiple
sources throughout the fab. This data, which ranges from detailed information
about the location and state of completion of wafer lots and the operational
status of individual process tools to high-level production plans and scheduling
information, is generated by various software systems running on computers
distributed throughout the fab, including individual tool control systems,
materials control systems, manufacturing execution systems and planning and
scheduling systems.

Bringing together these disparate hardware, software and data elements into
a unified factory automation system is a complex task. Because of the critical
role that factory automation systems play in the operation of the fab,
manufacturers demand that these systems provide proven performance and
reliability and be supplied by vendors that have broad expertise in the
semiconductor industry, a history of success in managing large factory
automation projects and the capability to provide responsive, global support.
Increasingly, semiconductor manufacturers are seeking vendors that can meet
these criteria to provide integrated factory automation solutions that not only
increase fab productivity and enhance manufacturers' control over their
production operations, but also increase their flexibility to add new capacity,
reduce the burden and risk of fab construction and improve the return on fab
investments.

STRATEGY

Our objective is to extend our position as the leading supplier of factory
automation systems for semiconductor manufacturing. To achieve this objective,
we are pursuing a business strategy to:

PROVIDE COMPREHENSIVE FACTORY AUTOMATION SOLUTIONS

We deliver integrated factory automation solutions and we intend to expand
and enhance our automation planning and design, project management, factory
integration and field engineering capabilities and product offerings to support
this approach. We believe that continued market leadership will require us to
offer comprehensive factory automation solutions for our customers. We will
continue to work closely with our customers to provide advanced products that
are integrated with the customers' specific manufacturing environments, conform
to industry standards and are compatible with tools and systems provided by
other suppliers. The modular design of our end-user and OEM products uses common
building blocks designed to work together in multiple configurations, to be
implemented without extensive customization and to be rapidly modified to
accommodate changes in a manufacturer's facilities, process sequence or process
tools. In addition, we provide a broad range of automation services designed to
ensure the successful, on-time deployment of our solutions.

STRENGTHEN CUSTOMER RELATIONSHIPS

Our customers include many of the world's leading providers of semiconductor
products and semiconductor process tools. We work closely with our customers to
address their most demanding factory automation needs. This interaction has
given us the opportunity to develop technology responsive to the most recent
advances in semiconductor manufacturing. Because of the geographical diversity
of our customer base and the numerous types of semiconductor products they
manufacture, we have also been called upon to help our customers solve a wide
variety of operational problems, enabling us to develop a broad range of
solutions and expertise. In addition, we believe that, as a result of the
substantial investment by our customers in our factory automation solutions and
the critical role played by our systems in our customers' manufacturing
operations, our relationships with these major customers provide opportunities
for additional sales, as customers expand the scope of installed

33
<PAGE>
solutions, construct new facilities or refurbish or retrofit existing fabs. We
will seek both to deepen our collaborative relationships with our customers as
well as to seek opportunities to develop similar relationships with others in
the semiconductor industry.

EXPAND PRODUCT OFFERINGS

Through internal development, joint ventures and alliances with other
suppliers and, potentially, through selective acquisitions, we will seek to add
new capabilities identified by our customers as important. We intend to continue
to broaden our product line to address a variety of factory automation needs,
ranging from the automation of individual process tools to implementation of
integrated, fab-wide factory automation systems in new and existing facilities.

INCREASE PENETRATION OF THE ASIA-PACIFIC MARKET

We believe that the Asia-Pacific market represents an important opportunity,
and we intend to continue our effort to penetrate and capture a significant
share of this market by deploying increased marketing, distribution, sales and
support resources in Japan and the rest of the Asia-Pacific region. The
semiconductor manufacturing industry is global in scope, with a significant
percentage of certain types of integrated circuits produced in the Asia-Pacific
region, most notably Japan, Singapore, South Korea and Taiwan. We have
established a significant market position in Singapore and Taiwan, and have
recently begun to penetrate the market in South Korea. We have competed
successfully with Japanese companies for orders from Japanese semiconductor
companies operating outside Japan, however we have yet to sell our factory
automation products for installation in Japan. We intend to increase our focus
on the Japanese market.

CAPITALIZE ON EMERGING 300MM WAFER AUTOMATION OPPORTUNITIES

As semiconductor manufacturers shift to 300mm wafer production, more factory
automation will be required than for existing 200mm wafer production. Certain
tasks that can be handled manually in a 200mm fab, such as loading and unloading
of process tools, must be automated because 300mm wafers are substantially
larger and heavier than 200mm wafers. In addition, the increased number of
integrated circuits on a 300mm wafer increases the risk of economic loss
associated with wafer damage caused by mishandling. We believe that factory-wide
automation systems, including automation of wafer movement within individual
process bays, will therefore be a necessity in 300mm production fabs. A typical
200mm fab presents a factory automation revenue opportunity of $10 million to
$15 million. For a full 300mm fab, the factory automation revenue opportunity is
expected to range from $50 million to $75 million. Over the past several years,
we have made significant investments in our 300mm automation systems. We believe
that the systems we have developed, including our intrabay automation systems,
are well positioned to capture a significant portion of 300mm fab automation
opportunities as they emerge.

PRODUCTS AND SERVICES

We provide our customers with a fully integrated line of factory automation
systems, software and services designed to automate the semiconductor
fabrication process and optimize the flow of products, data, materials and
resources throughout the fab. We have organized our product development,
marketing and sales functions to address a wide range of automation requirements
to improve manufacturing efficiency and increase productivity. Our key product
areas are:

- FACTORY AUTOMATION SYSTEMS that store, transport and manage the movement
of work-in-process wafers throughout the fab.

- TOOL AUTOMATION SYSTEMS that automate the movement of wafers into and out
of the process chamber and provide an integration point between the
factory automation systems and the process tool.

34
<PAGE>
- FACTORY MANAGEMENT SOFTWARE that manages and directs manufacturing
operations and optimizes material flow, process equipment and other
production resources.

- ADVANCED PLANNING AND SCHEDULING SOFTWARE that enables customers to
develop capacity plans and work-flow schedules to optimize fab-wide
operations and quickly react to changing business requirements.

- AUTOMATION SERVICES AND SUPPORT that help customers throughout the total
automation project lifecycle from initial conceptualization and design to
installing and servicing the equipment in the customer fab.

FACTORY AUTOMATION SYSTEMS

INTERBAY AUTOMATION. We are a leading supplier of interbay automation
systems. Interbay systems transport wafers throughout the factory and store them
in the bay where the next process step will occur. Our interbay automation
products consist of automated storage and retrieval systems linked by an
overhead monorail transport system, together with associated controllers,
software and communications capabilities to provide a tightly integrated wafer
flow solution. The majority of new fabs constructed since 1990 have adopted some
form of interbay automation system. Our interbay automation systems include:

- AEROTRAK OVERHEAD MONORAIL SYSTEMS--Our AeroTrak overhead monorail
transport systems provide clean and fast delivery of material from process
bay to process bay.

- TURBOSTOCKER AUTOMATED STORAGE AND RETRIEVAL SYSTEMS--Our TurboStocker
automated storage and retrieval systems, or stockers, are enclosed,
environmentally controlled structures that store work-in-process wafers in
various locations throughout the fab.

- INTERFLOOR AND INTERBUILDING TRANSPORT SYSTEMS--Interfloor and
interbuilding transport systems move wafers between different floors or
buildings of a fab.

INTRABAY AUTOMATION. Our intrabay products move wafers from storage systems
to individual process tools. Manufacturers anticipate that the shift to 300mm
wafers will require the extensive adoption of intrabay automation systems to
automate the movement of work-in-process wafers from one process tool loadport
to another. Our intrabay automation systems include:

- MACHINE LOADING ROBOT VEHICLE--Machine loading robot vehicles are guided
vehicles that utilize a track system embedded in the floor of the process
bay to transport wafers to and from the process tool.

- AEROLOADER OVERHEAD HOIST TRANSPORT SYSTEMS--Our AeroLoader overhead hoist
transport systems use a monorail to retrieve wafer pods from a stocker and
deliver them directly to the loadport at the process tool.

- AUTOMATED GUIDED VEHICLES--Automated guided vehicles are operator-free,
trackless vehicles that automate the movement of wafers within a process
bay from the stocker directly to the loadport of the process tool.
Automated guided vehicles are ideally suited for low-throughput
applications where floor space is less critical.

- PEOPLE GUIDED VEHICLES--People guided vehicles are manually operated
vehicles used to safely move materials across the fab and assist the
operator in transferring the wafer pod from the vehicle to the process
tool loadport. These vehicles can be used as a backup to automated
systems.

LITHOGRAPHY AUTOMATION SYSTEMS. We are a leading supplier of lithography
automation systems, which automate the storage, retrieval, tracking and delivery
of reticles and wafers within the lithography bay. Reticles are glass plates
containing the device images that are projected onto wafers during the
lithography process. As semiconductor manufacturing technology advances, the
cost of lithography tools, or steppers, is increasing. Also, as device
complexity increases, the number of reticles used in the

35
<PAGE>
manufacturing process increases, increasing the need for automation to improve
utilization and productivity. Since the lithography bay typically paces overall
fab output, productivity improvements in the lithography bay directly improve
overall fab throughput and productivity. Our lithography automation systems
include:

- BARE RETICLE STOCKERS--Bare reticle stockers provide a high-density
storage and retrieval solution for reticles that are stored without being
placed in a pod or box container. The bare reticle stocker protects the
reticle in an environmentally controlled system and saves expensive floor
space inside the lithography bay.

- RETICLE POD OR BOX STOCKERS--Reticle pod or box stockers provide clean and
safe storage for reticles that are stored in industry-standard pods or
boxes. The reticle pod and box stocker interfaces with our interbay
transport system, allowing the pod or box stocker to be placed anywhere in
the fab.

- COMBINATION RETICLE STOCKERS--Combination reticle stockers combine the
speed and convenience of a pod stocker with the high-density storage of a
bare reticle stocker for greater levels of reticle inventory management
and productivity in the lithography bay.

- RETICLE MANAGEMENT SOFTWARE--Reticle management software manages the use,
kitting and unkitting, delivery and maintenance of reticles for improved
reticle inventory management.

TOOL AUTOMATION SYSTEMS

We provide robotic systems that automate the transfer of wafers into and out
of process tools. The primary customers for these solutions are manufacturers of
process tool equipment. The automation systems are typically integrated directly
into the manufacturer's product before shipment to the end user. Our tool
automation systems include:

- ATMOSPHERIC WAFER-HANDLING SYSTEMS--We are a leading supplier of
atmospheric wafer-handling systems. These systems remove wafers from pods
or cassettes and align them prior to placing them into the process tool
chamber or metrology station.

- VACUUM WAFER-HANDLING SYSTEMS--Vacuum wafer-handling systems automate
wafer-handling within a vacuum chamber. Our vacuum products range from
individual vacuum robotic components to fully integrated vacuum cluster
platforms.

- EQUIPESOFT SYSTEM CONTROL SOFTWARE--Our EquipeSoft system control software
integrates, tracks and controls the wafer-handling robots within the
manufacturer's process tool.

- SFO INTEGRATED FRONT END SYSTEMS--Our SFO integrated front end systems
store work-in-process wafer cassettes, standard mechanical interface pods,
or 300mm front opening unified pods, or FOUPs, directly at the process
tool front-end. These systems also unload wafers from the FOUP, align them
and place them in the process tool. Our integrated front end systems
products include all SEMI-compliant interfaces to the factory automation
systems.

- 300MM LOADPORTS--Our 300mm loadports provide a simple and economical
method for opening and removing wafers from FOUPs.

- SPECIALTY WAFER-HANDLING SYSTEMS--We provide other wafer-handling systems.
These specially designed robots are used in a variety of wafer-handling
applications including chemical mechanical planarization, copper
interconnect processing and other robotic wafer-handling applications.

FACTORY MANAGEMENT SOFTWARE

As more of the semiconductor manufacturing process becomes automated, we
believe that software will play an increasingly important role in a
manufacturer's ability to improve the productivity of its overall fab
operations. Our software products address the most important aspects of wafer
flow logistics

36
<PAGE>
to deliver a complete software management solution that addresses fab-wide
operations. Our factory management software offerings include:

- MANUFACTURING EXECUTION SYSTEM, OR MES, SOFTWARE--Our MES software manages
and directs complex manufacturing operations by automating process
specification and control. Our PROMIS software bridges business planning
systems and material processing in the factory to optimize the flow of
material and improve process equipment utilization. We expect to introduce
our next-generation MES software offering, Encore!, in late fiscal 2000.

- FABUILDER MANUFACTURING INTEGRATION SOFTWARE--FAbuilder, our manufacturing
integration software, reduces the time required to deploy process tool
automation and provides a flexible solution for distributing and
maintaining equipment automation throughout the fab.

- TRANSNET MATERIAL CONTROL SOFTWARE--Our TransNet material control software
directs the movement of wafers throughout the fab and is integrated with
our interbay and intrabay automation systems.

ADVANCED PLANNING AND SCHEDULING SOFTWARE

Our planning and scheduling software offerings enable semiconductor
manufacturers to increase their return on investment by maximizing production
efficiency, prioritizing the production of high-margin or high-demand customer
orders and minimizing the disruption caused by limited process tool
availability. Our advanced planning and scheduling software offerings include:

- LEVERAGE FOR PLANNING SOFTWARE--Our Leverage for Planning software product
enables customers to develop capacity plans to optimize wafer starts and
quickly react to changing business requirements.

- LEVERAGE FOR SCHEDULING SOFTWARE--When released for commercial sale in the
second half of fiscal 2000, our Leverage for Scheduling software product
will enable customers to develop and modify work-flow schedules that
optimize fab-wide operations based on many factors, including process tool
availability, demand for specific semiconductor batches or types and
changing business and technical requirements.

AUTOMATION SERVICES AND SUPPORT

We provide a variety of automation services and support that are essential
to the success of large-scale factory automation projects. These include:

- AUTOMATION PLANNING AND DESIGN SERVICES--We work with customers in
assessing their automation needs during the design phase of a project to
build or upgrade a fab. We develop a complete automation plan identifying
the type and configuration of the automation systems and simulate the
design using computer modeling techniques to verify that the design layout
meets customer requirements.

- PROJECT MANAGEMENT SERVICES--We provide customers with project management
support during the building and manufacturing of the automation systems.

- INSTALLATION SERVICES--We develop an installation plan and timetable that
meets the customer's manufacturing schedule and install the equipment in
the customer's fab.

- POST-INSTALLATION SERVICE AND SUPPORT--We provide a variety of
post-installation services to ensure the automation systems continue to
operate at optimum performance levels.

37
<PAGE>
MARKETING, SALES AND CUSTOMER SUPPORT

We market our products worldwide to semiconductor manufacturers and OEM
semiconductor capital equipment suppliers. In North America, we sell and support
our products through a direct sales and support organization operating out of
our headquarters in Billerica, Massachusetts and regional offices located in
California and Texas. In Europe, our products are sold and supported by a direct
sales and support organization with offices in France, Germany, Ireland, Israel,
Switzerland and the United Kingdom. In Asia, our products are sold and supported
by a direct sales and support organization with offices in Japan, Singapore,
South Korea and Taiwan.

We offer a variety of service programs to meet a broad range of customer
requirements. These services can range from telephone hot-line support to
full-time, on-site customer service provided by our personnel based at the
customer's facility. We maintain a fully staffed and equipped training center at
our Billerica, Massachusetts headquarters to support the training requirements
of our customers.

COMPETITION

Rapid technological change and intense competition characterize the
semiconductor capital equipment market. Our factory automation division competes
with Daifuku, Murata Machinery, Shinko Electric and a number of other smaller
foreign and domestic manufacturers of automated machinery used in semiconductor
fabrication facilities. Our tool automation systems division competes with
Genmark Automation, Asyst Technologies, Brooks Automation and a number of other
foreign and domestic wafer-handling robotics companies, including in-house
organizations of process tool manufacturers that develop their own automation
technology, as well as other smaller robotics companies. Our software products
compete with products provided by Consilium, a subsidiary of Applied Materials,
Brooks Automation and other vendors. We believe that competition in our industry
is likely to intensify.

We believe that the market for our products is characterized by market
pressures on semiconductor manufacturers to increase productivity and reduce
costs. We compete on the basis of product performance, quality, reliability,
customer service and support, delivery capability and price. We believe that we
have the following competitive advantages in the factory automation market:

- a broad range of integrated and flexible factory automation systems and
factory management software products;

- technological leadership;

- experience in managing large factory automation projects;

- domain expertise in automation applications;

- specialized manufacturing skills; and

- a worldwide customer support infrastructure.

However, existing or future competitors, particularly those with greater
resources than ours, or who are able to bring technologically superior products
to market, could overcome these competitive advantages.

We believe that once a semiconductor manufacturer selects a vendor's
equipment for a particular fab, the manufacturer may continue to rely upon that
equipment for a specific application in other fabs. Accordingly, we may have
difficulty selling to potential customers that have selected a competitor's
equipment, and we expect that difficulty to last for a significant period of
time. However, at least one of our significant customers has adopted a policy of
maintaining multiple vendors for the products it purchases. This kind of policy
could limit additional sales to existing customers. In addition, the expected
transition to 300mm technology may cause new competitors to enter our markets
and may diminish our competitive advantage with customers for whom we are the
incumbent supplier of automation equipment. In the face of increased
competition, we may need to lower our prices, which could seriously harm our
business.

38
<PAGE>
RESEARCH AND DEVELOPMENT

We continuously invest in the development of new products to improve
performance and reliability and to introduce new functionality in order to
maintain our leading position in providing factory automation systems and
software. The ongoing development of technologies and products, particularly
relating to 300mm technology, is vital to our success. Our research and
development expenses were $36.2 million, or 15% of total net revenue, in fiscal
1997, $44.5 million, or 22% of total net revenue, in fiscal 1998,
$45.5 million, or 33% of total net revenue, in fiscal 1999 and $12.2 million, or
21% of total net revenue, in the three months ended January 2, 2000.

CUSTOMERS

Our customers include many of the leading global manufacturers of
semiconductors, as well as OEM semiconductor equipment suppliers in the United
States, Europe and the Asia-Pacific region. Historically, a significant portion
of our total net revenue for any particular period has been attributable to
sales to a limited number of customers. Sales to our top ten customers accounted
for 67% of total net revenue in fiscal 1997, 60% of total net revenue in fiscal
1998 and 54% of total net revenue in fiscal 1999.

Our largest customers change from year to year, as large projects are
completed and new projects are initiated. Sales to Intel accounted for 32% of
total net revenue in fiscal 1997, 19% of total net revenue in fiscal 1998 and
21% of total net revenue in fiscal 1999. At September 30, 1999, Intel and Texas
Instruments accounted for 13% and 10% of our backlog, respectively.

BACKLOG

Our backlog at January 2, 2000 was $106.6 million, compared to
$86.4 million at September 30, 1999 and $40.4 million at December 27, 1998. We
include in backlog only those customer orders for products, spare parts and
services for which we have accepted signed purchase orders with assigned
delivery dates within twelve months. Tool automation products and software
products typically have shorter lead times than do factory automation products.
Therefore, backlog is not a relevant indicator of business levels for these
products.

MANUFACTURING

Our manufacturing operations take place in Billerica, Massachusetts and in
Mountain View, California. Our manufactured products consist of standard
components that can be customized to meet unique customer requirements. Our
manufacturing operations consist primarily of assembly and test functions, with
fabrication of most components and subassemblies outsourced to key suppliers.
Completed subassemblies are tested for functionality prior to their assembly
into completed systems. Completed systems are subjected to functional testing
prior to shipment. We expect to continue to seek to outsource manufacturing
operations with the objective of reducing costs and increasing our flexibility
to respond to changes in semiconductor demand.

Our manufacturing department is responsible for managing the transition of
new products from engineering to production, and for improving manufacturing
efficiency. We operate a "concurrent engineering" process to provide an
effective integration of disciplines from design through manufacturing,
acceptance, testing and installation. Our objective is not only to meet
customers' delivery deadlines, but to ensure that products are designed so they
can be manufactured at the lowest cost while providing the reliability,
serviceability and support required by customers.

We have implemented quality control and quality assurance processes based on
total quality management principles. Quality control is maintained through
inspections of components and in-process inspection and testing of
subassemblies. After all manufacturing operations are completed, our quality
assurance personnel perform final test and acceptance of each system to ensure
that it meets product specifications and quality standards prior to shipment to
the customer.

<PAGE>
We have implemented a supplier excellence program to assist management in
qualifying and selecting external suppliers. By more effectively managing our
external supplier base, we can maximize the suppliers' technical capabilities to
provide us with the flexibility and capacity utilization needed to meet
production requirements and lower our costs. Our commodity management group
works closely with the design and manufacturing engineering groups to provide
multiple sources for most components.

INTELLECTUAL PROPERTY RIGHTS

While we believe that our success will depend more upon our technological
expertise and the capabilities of our employees than upon protection through the
legal system of our intellectual property rights, our success also depends to a
significant degree upon our patent for certain key elements of our monorail
system, our other patents, our source code and our other proprietary technology.
At January 2, 2000, we held seven U.S. patents relating to certain key elements
of our wafer-handling systems. We also had 16 U.S. patent applications pending,
and we intend to file additional patent applications as appropriate. Our patents
expire at various times from 2007 to 2019. We cannot predict whether any patents
will issue from our patent applications, or whether any of our issued patents or
subsequently issued patents will provide any meaningful protection. We also seek
to protect our trade secrets and other proprietary technology through
confidentiality agreements with employees, consultants and other parties. The
steps we have taken to protect our technology may be inadequate. If so, we might
not be able to prevent others from using what we regard as our technology to
compete with us. For example, our patents could be challenged, invalidated or
circumvented, and the rights we have under our patents could provide no
competitive advantages. Existing trade secret, copyright and trademark laws
offer only limited protection. In addition, the laws of some foreign countries
do not protect our proprietary technology to the same extent as the laws of the
United States. Other companies could independently develop similar or superior
technology without violating our proprietary rights. Any misappropriation of our
technology or the development of competitive technology could seriously harm our
business.

EMPLOYEES

At January 2, 2000, we had 1,194 full-time employees. In addition, we
utilize the services of temporary or contract personnel within some functional
areas to assist on project-related activities. The number of temporary or
contract personnel varies depending on specific project activity. At January 2,
2000, we employed 135 temporary or contract personnel. We believe that our
future success will depend in large part on our ability to attract and retain
highly skilled employees. None of our employees is covered by a collective
bargaining agreement. We consider our relationship with our employees to be
good.

FACILITIES

Our corporate headquarters are located in a 122,342-square foot leased
building in Billerica, Massachusetts. The lease on this facility expires in
2001. We also lease three additional facilities, with lease expiration dates in
2000 and 2001, in Billerica, Massachusetts, with a total of 117,100 square feet.
Our Billerica, Massachusetts facilities are primarily used by our factory
automation systems division for engineering and manufacturing. We also lease
facilities in Austin, Texas, Mountain View, California, Mesa, Arizona, and
Toronto, Ontario, as well as France, Germany, Japan, Singapore, South Korea,
Switzerland, Taiwan and the United Kingdom, under leases with expiration dates
ranging from May 2000 to November 2006. We believe that our existing facilities
will be adequate to meet our currently anticipated requirements and that
suitable additional or substitute facilities will be available as required.

</TABLE>

The underwriters are offering the shares of common stock subject to their
acceptance of the shares from us and the selling stockholders and subject to
prior sale. The underwriting agreement provides that the obligations of the
several underwriters to pay for and accept delivery of the shares of common
stock offered by this prospectus are subject to the approval of legal matters by
their counsel and to other conditions. The underwriters are obligated to take
and pay for all of the shares of common stock offered in this offering, other
than those covered by the over-allotment option described below, if any of the
shares are taken.

The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price set forth on the cover
page of this prospectus and part to selected dealers at a price that represents
a concession not in excess of $2.08 a share under the public offering price. No
underwriter may allow, and no such dealers may reallow, a concession to any
underwriter or to certain other dealers. After the initial offering of the
shares of common stock, the offering price and other selling terms may from time
to time be varied by the representatives of the underwriters.

We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to an aggregate of 255,750
additional shares of common stock at the public offering price set forth on the
cover page of this prospectus, less underwriting discounts and commissions. The
underwriters may exercise this option solely for the purpose of covering
over-allotments, if any, made in connection with the offering of the shares of
common stock offered in this offering. To the extent such option is exercised,
each underwriter will become obligated to purchase approximately the same
percentage of such additional shares of common stock as the number set forth
next to such underwriter's name in the preceding table bears to the total number
of shares of common stock set forth next to the names of all underwriters in the
preceding table. If the underwriters' over-allotment option is exercised in
full, the total price to the public would be $125,488,000, the total
underwriters' discounts and commissions would be $6,274,400, and the total
proceeds to us would be $100,669,600, before deducting offering expenses payable
by us.

45
<PAGE>
We will pay the expenses of the offering, which we estimate will be
approximately $500,000.

We, our directors and executive officers and the selling stockholders have
agreed that, without the prior written consent of Morgan Stanley & Co.
Incorporated on behalf of the underwriters, during the period ending 90 days
after the date of this prospectus, we and each of them will not directly or
indirectly:

- offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right
or warrant to purchase, lend or otherwise transfer or dispose of, directly
or indirectly, any shares of common stock or any securities convertible
into or exercisable or exchangeable for common stock; or

- enter into any swap or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of common
stock,

whether any such transaction described above is to be settled by delivery of
common stock or such other securities, in cash or otherwise.

The restrictions described in the previous paragraph do not apply to:

- the sale of up to 100,000 shares by Mordechai Wiesler, less any shares
sold by Mr. Wiesler in this offering, the sale of up to 75,000 shares by
Mitchell G. Tyson, less any shares sold by Mr. Tyson in this offering, and
the sale of up to 100,000 shares by Amram Rasiel, less any of shares sold
by Mr. Rasiel in this offering, provided in each case that such sales are
made pursuant to Rule 144 under the Securities Act and after the
expiration of the 30-day period following the date of this prospectus;

- the sale of shares of common stock to the underwriters under the
underwriting agreement;

- our issuance of shares of our common stock upon the conversion of
exchangeable shares outstanding on the date of this prospectus;

- transactions by any person other than us relating to shares of common
stock or other securities acquired in open market transactions after the
completion of the offering of the shares of common stock; and

- issuances of shares of common stock or options to purchase shares of
common stock pursuant to our employee benefit plans as in existence on the
date of the prospectus and consistent with past practices.

The underwriters have informed us that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
common stock offered by them.

Our common stock is listed on the Nasdaq National Market under the symbol
"PRIA."

In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the common stock for
their own account. In addition, to cover over-allotments or to stabilize the
price of the common stock, the underwriters may bid for, and purchase, shares of
common stock in the open market. Finally, the underwriting syndicate may reclaim
selling concessions allowed to an underwriter or a dealer for distributing the
common stock in the offering, if the syndicate repurchases previously
distributed shares of common stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the common stock above independent
market levels. The underwriters are not required to engage in these activities,
and may end any of these activities at any time.

From time to time, some of the underwriters have provided, and may continue
to provide, investment banking services to us.

PRI and the selling stockholders have agreed to indemnify each other and the
underwriters against stated liabilities, including liabilities under the
Securities Act of 1933 (the "Securities Act").

The validity of the shares of common stock offered hereby will be passed
upon for us by Foley, Hoag & Eliot LLP, Boston, Massachusetts. A member of that
firm beneficially owns 4,000 shares of our common stock. Legal matters in
connection with this offering will be passed upon for the underwriters by Testa,
Hurwitz & Thibeault, LLP, Boston, Massachusetts.

DISCLOSURE OF SEC POSITION ON
INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Our articles of organization provide that, subject to certain exceptions, we
will indemnify and hold harmless each of our officers and directors to the
fullest extent authorized by the Massachusetts Business Corporation Law, and
that we may also, to the extent authorized by the Board of Directors, indemnify
and advance expenses to any employee or agent of PRI. The Massachusetts Business
Corporation Law generally authorizes a corporation to indemnify its directors,
officers, employees and other agents unless such person is adjudicated in any
proceeding not to have acted in good faith in the reasonable belief that his
action was in the best interests of the corporation.

Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling PRI pursuant to
the foregoing provisions, we have been informed that in the opinion of the SEC
such indemnification is against public policy as expressed in the Securities Act
and is therefore unenforceable.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
PRI Automation, Inc.:

In our opinion, based upon our audits and the report of other auditors, the
accompanying consolidated balance sheets and the related consolidated statements
of operations, of stockholders' equity and of cash flows present fairly, in all
material respects, the financial position of PRI Automation, Inc. and its
subsidiaries at September 30, 1999 and 1998, and the results of their operations
and their cash flows for each of the three years in the period ended
September 30, 1999, in conformity with generally accepted accounting principles
in the United States. 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. The consolidated financial statements
give retroactive effect to the merger of Promis Systems Corporation Ltd. in a
transaction accounted for as a pooling of interests, as described in Note N to
the consolidated financial statements. We did not audit the consolidated
financial statements of Promis Systems Corporation Ltd., which statements, not
included herein, reflect total revenues of $23,967,000, before conforming
accounting policy adjustments, for the year ended December 31, 1997. Those
statements were audited by other auditors whose report thereon has been
furnished to us, and our opinion expressed herein, insofar as it relates to the
amounts included for Promis Systems Corporation Ltd., is based solely on the
report of the other auditors. We conducted our audits of these statements in
accordance with generally accepted auditing standards in the United States,
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 and the report of
other auditors provide a reasonable basis for the opinion expressed above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A. DESCRIPTION OF BUSINESS:

PRI Automation, Inc. (the "Company") is a leading global supplier of factory
automation systems and factory management software for semiconductor
manufacturers and of automation systems that are incorporated in semiconductor
process tools manufactured by original equipment manufacturers. The Company is
subject to risks and uncertainties common to companies in the semiconductor
industry including, but not limited to, the highly cyclical nature of the
semiconductor industry leading to recurring periods of over-supply, rapid
technological change and the development by the Company or its competitors of
new technological innovations, dependence on key personnel, the protection of
proprietary technology, management of inventory and manufacturing capacity,
fluctuations in operating results, doing business in Asian and European markets
and related currency risks, competitive pressure on selling prices, the timing
and cancellation of customer orders and the Company's ability to absorb and
manage acquisitions.

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of PRI
Automation, Inc., its wholly owned domestic subsidiaries and its wholly owned
and majority-owned foreign subsidiaries (collectively, the "Company"). All
significant intercompany transactions and balances have been eliminated. Certain
reclassifications have been made to prior years' financial statements to conform
to the current presentation.

In March 1999, the Company acquired Promis Systems Corporation Ltd.
("Promis"). In January 1998, the Company acquired Equipe Technologies, Inc.,
E-Machine, Inc., and Equipe Japan Ltd. (collectively, "Equipe"). In May 1998,
the Company acquired Chiptronix Handling Systems GmbH ("Chiptronix"), the
European distributor of Equipe products. The acquisitions of Promis, Equipe and
Chiptronix were accounted for using the pooling-of-interests method of
accounting. All prior period historical consolidated financial statements
presented herein have been restated to include the financial position, results
of operations, and cash flows of Promis and Equipe. The Company has not restated
its financial statements for the acquisition of Chiptronix because the effect of
restatement is immaterial.

UNAUDITED INTERIM FINANCIAL INFORMATION

The interim financial data as of January 2, 2000 and for the three months
ended January 2, 2000 and December 27, 1998 is unaudited; however, in the
opinion of the Company, the interim data includes all adjustments, consisting
only of normal recurring adjustments, necessary for a fair statement of the
results for the interim periods. The results for interim periods are not
necessarily indicative of the results for the entire year. For interim reporting
purposes, the Company closes its first three fiscal quarters on the Sunday
nearest the last day of December, March and June in each year. The Company's
fiscal year ends on the last day of September.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual

F-7
<PAGE>
PRI AUTOMATION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
results could differ from those estimates and would impact future results of
operations and cash flows. Significant estimates are inherent in determining
revenue recognition and associated profits under the percentage-of-completion
method.

CASH AND CASH EQUIVALENTS

Cash equivalents consist of commercial paper, Eurodollars, money market
mutual funds, short-term guaranteed investment certificates and other highly
liquid investments with original maturities of three months or less.

MARKETABLE SECURITIES

Current marketable securities include all investments with remaining
maturities of twelve months or less. Non-current marketable securities include
all investments with remaining maturities greater than twelve months. The
Company classifies all securities as available-for-sale. These securities are
reported at fair value as of the balance sheet date with net unrealized holding
gains and losses included in stockholders' equity. Gains and losses on sales of
securities are calculated using the specific identification method. The Company
did not hold any marketable securities as of September 30, 1998 and 1999. Gross
realized gains and losses for the year ended September 30, 1997 were $9,000 and
$7,000, respectively. Gross unrealized gains and losses at September 30, 1997
were $3,000 and $1,000, respectively. Gross realized gains and losses from
marketable securities for the year ended September 30, 1998 were $6,000 and
$1,000, respectively. Interest income included in other income, net was
$1,523,000, $1,991,000 and $2,233,000 for the years ended September 30, 1997,
1998 and 1999, respectively.

FINANCIAL INSTRUMENTS

Financial instruments that potentially subject the Company to significant
concentrations of financial or credit risk consist principally of cash and cash
equivalents, current and non-current marketable securities, trade accounts
receivable, accounts payable and debt. The Company generally invests its cash
and investments in investment-grade securities. The carrying value of financial
instruments approximates their related fair values.

The Company's customers are primarily concentrated in one industry, the
semiconductor manufacturing and related capital goods industry. Historically,
significant portions of the Company's sales have been to a limited number of
customers within this industry. The Company performs ongoing credit evaluations
of its customers' financial condition, and may require deposits on large orders
but does not require collateral or other security to support customer
receivables.

OFF-BALANCE SHEET RISK

The Company has entered into forward contracts in Canadian dollars to hedge
the expected operating expenses of its Canadian subsidiary that are denominated
in Canadian dollars. These contracts are used to mitigate the Company's risk
associated with exchange rate movements, as gains and losses on these contracts
are intended to offset exchange losses and gains on underlying cost exposures.
These contracts do not qualify for hedge accounting. The contract periods which
do not exceed sixteen months expire monthly through December 1999. The Company
does not enter into

F-8
<PAGE>
PRI AUTOMATION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
forward currency contracts for speculative purposes. Both realized and
unrealized gains and losses on the contracts are classified as components of
other income, net, in the consolidated statement of operations. At
September 30, 1999, the notional amount of outstanding forward currency
contracts was $1,914,000, which was marked to market and recognized in the
consolidated statements of operations.

The fair value of these contracts as of September 30, 1998 and 1999,
determined by applying fiscal year end currency exchange rates to the notional
contract amounts, represented a net unrealized loss of $60,000 and net
unrealized gain of $131,000, respectively.

RETAINAGES

Accounts receivable include certain amounts which are not due until final
customer acceptance or until contract provisions allow for billing. Such
retainages were approximately $13,832,000 and $9,605,000 at September 30, 1998
and 1999, respectively. The retainages are expected to be collected within the
next twelve months.

CONTRACTS IN PROGRESS

Contracts in progress include costs and estimated profits under incomplete
contracts accounted for using the percentage-of-completion method, net of
amounts billed. These amounts are expected to be collected within the next
twelve months as units are delivered. Amounts billed at September 30, 1998 and
1999 were $24,757,000 and $7,701,000, respectively.

INCOME TAXES

The Company recognizes deferred tax assets and liabilities based on
temporary differences between the financial statement and tax bases of assets
and liabilities using the expected tax rates in the year in which the
differences are expected to reverse. The Company provides a valuation allowance
against net deferred tax assets if, based on the available evidence, it is more
likely than not that some or all of the deferred tax assets will not be
realized. Equipe Technologies, Inc. and one of the related companies,
E-Machine, Inc., elected to be treated as an S-corporation under the provisions
of the Internal Revenue Code, prior to their acquisition by the Company, and as
such, the shareholders of Equipe Technologies, Inc. and E-Machine, Inc. were
liable for individual federal and certain state income taxes on their allocated
portions of the respective company's taxable income. Accordingly, U.S. income
tax expense related to Equipe Technologies, Inc. and E-Machine, Inc. was not
recorded by the Company for all periods through January 22, 1998, the date of
consummation of the merger with the Company (see Note O) except that Equipe
Technologies, Inc. and E-Machine, Inc. were subject to California franchise tax
based on 1.5% of taxable income.

INVENTORIES

Inventories, consisting of raw materials, work-in-process and finished
goods, are stated at the lower of cost (determined principally on a first-in,
first-out basis) or market.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Betterments and major renewals
are capitalized and included in property and equipment, while repairs and
maintenance are charged to expense as incurred.

F-9
<PAGE>
PRI AUTOMATION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
Depreciation and amortization of property and equipment are primarily provided
using the straight-line method over the estimated useful lives of the assets.
The amortization of assets recorded under capital leases is included in
depreciation and amortization expense. Upon retirement or sale, the cost of the
assets disposed and the related accumulated depreciation are removed from the
accounts and any resulting gain or loss is credited or charged to operations.

OTHER ASSETS

Goodwill, included in other assets, represents the excess of the purchase
price over the fair value of net assets acquired and is amortized on a straight
line basis over ten years. Goodwill was fully amortized as of September 30,
1999. Additionally, other intangible assets, including intellectual property
acquired in Promis' MASE acquisition and capitalized software licenses are
amortized on a straight line basis over the estimated useful lives of the assets
ranging from two to five years. The Company periodically reviews the value of
intangible assets in relation to the expected associated undiscounted cash flows
in order to assess whether there has been a permanent impairment in carrying
value. The Company believes that no significant impairment has occurred.

BILLINGS IN EXCESS OF REVENUES

Billings in excess of revenues include amounts billed on incomplete
contracts, accounted for using the percentage-of-completion method net of costs
and estimated profits recognized.

REVENUE RECOGNITION

For certain contracts eligible under American Institute of Certified Public
Accountants ("AICPA") Statement of Position No. 81-1, revenue on product sales
is recognized using the percentage-of-completion accounting method based upon an
efforts-expended method. In all cases, changes to total estimated costs and
anticipated losses, if any, are recognized in the period in which determined.
Revenue recognized under the percentage-of-completion accounting method was
approximately $100,699,000, $54,999,000 and $23,383,000 during fiscal years
1997, 1998 and 1999, respectively. Revenue from product sales not recognized
under the percentage-of-completion method is generally recorded upon shipment to
the customer, provided that no significant vendor obligations remain outstanding
and that collection of the related receivable is deemed probable by management.
Software license revenue is recognized upon delivery of the software and receipt
of a written agreement from the customer, provided that acceptance is not
uncertain, fees are fixed and determinable and collectibility of the related
receivable is deemed probable by management. Revenues from training and
consulting are recognized as services are performed. Service revenue is
recognized ratably over applicable contract periods or as the services are
performed. Additionally, the Company accrues for warranty costs upon shipment.
Product and equipment net revenue includes revenue from all equipment sales,
installation, project management and software licenses. Service and maintenance
net revenue consists of service contracts, spare part sales, repairs and
upgrades, software maintenance contracts and consulting and training services.

COMMISSIONS

The Company pays certain commissions to agents and distributors under
certain agreements in return for obtaining orders; and, in certain cases,
providing installation and warranty services.

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
Commissions that are due upon the Company receiving payment in full from the
customers are charged against the related revenues. These amounts totaled
approximately $2,381,000 and $98,000 for fiscal years 1997 and 1998,
respectively. No such commissions were paid in fiscal 1999.

RESEARCH AND DEVELOPMENT COSTS

The Company expenses all engineering, research and development costs as
incurred. Expenses subject to capitalization in accordance with SFAS No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise
Marketed," were insignificant.

FOREIGN CURRENCY TRANSLATION

Assets and liabilities of foreign subsidiaries which are denominated in
foreign currencies are remeasured into U.S. dollars at rates of exchange in
effect at the end of the fiscal year, except for nonmonetary assets and
liabilities, which are remeasured using historical exchange rates. Revenue and
expense amounts are remeasured using an average of exchange rates in effect
during the period, except those amounts related to nonmonetary assets and
liabilities, which are remeasured at historical exchange rates. The Company's
functional currency is the U.S. dollar for all of its subsidiaries. Net realized
and unrealized gains and losses resulting from foreign currency remeasurement
are included in the consolidated statements of operations as other income or
expense.

ACCOUNTING FOR STOCK-BASED COMPENSATION

The Company continues to apply the accounting provisions of Accounting
Principles Board ("APB") Opinion 25 and has elected the disclosure-only
alternative permitted under Statement of Financial Accounting Standards ("SFAS")
No. 123, "Accounting for Stock-Based Compensation." The Company has disclosed
pro forma net income (loss) and pro forma net income (loss) per share in the
footnotes using the fair value based method.

NET INCOME (LOSS) PER COMMON SHARE

Basic net income (loss) per common share is based upon the weighted average
number of common shares outstanding during each period. Diluted net income
(loss) per common share gives effect to all dilutive potential common shares
outstanding during the period. The computation of diluted net income (loss) per
common share does not assume the issuance of potential common shares that have
an anti-dilutive effect.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. The statement requires companies to
recognize all derivatives as either assets or liabilities, with the instruments
measured at fair value. The accounting for changes in fair value, gains or
losses, depends on the intended use of the derivative and its resulting
designation. The statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 2000. The Company will adopt SFAS No. 133 by fiscal
2001, in accordance with SFAS No. 137, which deferred the

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
effective date of SFAS No. 133. The Company is evaluating SFAS No. 133 to
determine the impact on its consolidated financial statements.

In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements"
("SAB 101"). SAB 101 summarizes the staff's view in applying generally accepted
accounting principles to selected revenue recognition issues. The application of
the guidance in SAB 101 will be required in the Company's first quarter of the
fiscal year 2001. The effects of applying this guidance will be reported as a
cumulative effect adjustment resulting from a change in accounting principle.
The Company has not completed its evaluation of SAB 101 and is therefore unable
to determine its impact.

H. STOCKHOLDERS' EQUITY:

STOCK OPTIONS

During 1984, the Board of Directors voted to adopt the 1984 Incentive Stock
Option Plan (the "1984 Option Plan") and subsequently reserved 1,050,000 shares
of its authorized common stock for issuance under this plan. On March 17, 1994,
the Board of Directors approved the 1994 Incentive and Nonqualified Stock Option
Plan (the "1994 Option Plan") and reserved 810,000 shares of common stock for
issuance under this plan. At the Company's annual stockholder meeting held on
January 26, 1996, the shareholders voted to increase the number of shares
authorized for issuance under the 1994 Option Plan to 1,810,000 shares. In 1997,
the Board of Directors voted to adopt the 1997 Non-Incentive Stock Option Plan
(the "1997 Option Plan") which authorizes the issuance of non-qualified options
to purchase up to an aggregate of 1,400,000 shares of common stock. The Board of
Directors has also granted non-qualified options to directors of the Company.
Incentive stock options generally vest over five years and expire six years
after issuance. Non-qualified stock options generally vest between zero and five
years and expire between five and ten years after issuance. Additionally, the
Company assumed Promis' obligations under its Amended and Restated Stock Options
Plan dated September 30, 1998. The Promis plan reserved 290,895 options, as
converted, for available grants by the Company's Board of Directors.

On July 1, 1998, the Compensation Committee of the Board of Directors, in an
effort to restore the long-term incentive feature of employee stock options that
were significantly out of the money, voted to provide employees with the
opportunity to exchange options dated April 1, 1997 and thereafter for new
options with an exercise price of $14.75, the then fair market value of the
Company's common stock. Options to purchase 1,637,300 shares of common stock
with an average exercise price of $27.98 were canceled and replaced with an
equal number of stock options effective July 17, 1998. The vesting period
started over again on repriced options.

EMPLOYEE STOCK PURCHASE PLAN

Since May 1994, the Company has offered an Employee Stock Purchase Plan
("ESPP") under which rights are granted to purchase shares of common stock at
85% of the lesser of the market value of such shares at either the beginning or
the end of each six month offering period. The plan permits employees to
purchase common stock through payroll deductions, which may not exceed 10% of an
employee's compensation as defined in the plan. The Company, in 1994, had
reserved 450,000 shares of common stock for issuance to eligible employees.
Shares purchased during fiscal years 1997, 1998 and 1999, were 49,044, 114,996
and 171,436, respectively, at average prices ranging from $9.78 to $22.26 per
share. Shares available for future purchase under the ESPP totaled 9,320 at
September 30, 1999.

STOCK-BASED COMPENSATION PLANS

The Company applies APB Opinion No. 25 and related Interpretations in
accounting for its stock-based compensation plan and accordingly, no
compensation expense has been recognized for options granted to employees and
shares purchased under these plans. Had compensation expense for the stock-based
compensation plans been determined based on the fair value at the grant dates
for options granted and shares purchased under the plans consistent with the
method of SFAS No. 123, "Accounting for Stock-Based Compensation," the net
income (loss) and net income (loss) per diluted share for the years ended
September 30 would have been as follows:

<TABLE>
<CAPTION>

Net income (loss):

</TABLE>

The effects of applying SFAS No. 123 in this pro forma disclosure are not
likely to be representative of the effects on reported net income for future
years, because SFAS 123 does not apply to awards granted prior to fiscal year
1996 and additional awards are anticipated in future years.

The estimated weighted average fair value of options granted in fiscal year
1997, 1998 and 1999, to purchase the Company's common stock, were $11.87, $12.78
and $16.86, respectively. The fair value of options at the date of grant was
estimated using the Black-Scholes option pricing model with the following
weighted average assumptions:

The fair value of ILC options at the date of grant was estimated using the
Black-Scholes option pricing model with the following assumptions: expected life
of one year to four years, risk-free interest rate of 4.84% to 5.77%, volatility
of 85% and dividend yield of 0. The estimated weighted average fair value of
options granted in fiscal year 1998 and 1999 was $0.07 and $0.13, respectively.

STOCK WARRANTS

Pursuant to an agreement dated February 26, 1996, prior to the acquisition
of Promis by the Company, Promis issued and sold 270,600 warrants, converted at
the common stock exchange ratio of 0.1353, at $22.09 per warrant for aggregate
proceeds of $6.6 million. Each warrant was convertible into

one common share. The associated costs of the warrants offering were
approximately $0.6 million. On June 16, 1997, the 270,600 warrants were
converted into 270,600 common shares.

On May 1, 1996, Promis granted warrants to a third party to purchase up to
13,530 common shares, as converted at the common stock exchange ratio. These
warrants have an expiration date of April 30, 2000.

RIGHTS AGREEMENT

The Board of Directors of the Company adopted a Rights Agreement, dated as
of December 9, 1998, between the Company and State Street Bank and Trust
Company, as Rights Agent. In connection with this agreement, the Board
distributed one common share purchase right for each share of common stock then
or thereafter outstanding. The rights will become exercisable only if a person
or group acquires beneficial ownership of 20% or more of the outstanding common
shares of the Company. Each right, when it becomes exercisable, will entitle the
holder to purchase from the Company one one-hundredth of a share of Series A
Participating Cumulative Preferred Stock, par value $0.01 per share, of the
Company, at a price of $140. Prior to any party acquiring 20% or more of the
outstanding common shares of the Company or prior to the expiration date, the
Board of Directors of the Company may redeem the rights in whole, but not in
part, at a price, in cash or common shares or other securities of the Company
deemed by the Board of Directors to be at least equivalent in value, of $.001
per right. The rights expire on December 9, 2008 unless otherwise redeemed by
the Company prior to that date.

I. CONTINGENT LIABILITY:

At January 2, 2000, the Company had a contingent liability of approximately
$142,000. In 1993, Promis purchased the business assets and assumed selected
liabilities of Palette Systems, Inc., a Canadian company (the "sellers"). The
purchase price of approximately $9.9 million consisted of $5.5 million in cash
and 59,889 exchangeable common shares, as converted at the common stock exchange
ratio, of the Company, valued at $73.91 per common share. At the time of the
acquisition, Promis agreed that on April 7, 1998 it would pay additional cash
consideration to the sellers of an amount equal to the amount by which
approximately $4.0 million exceeded the market value of the common shares owned
by the sellers on April 7, 1998.

On March 29, 1996, Promis made a formal claim against the sellers pursuant
to the dispute resolution provisions of the original purchase and sale
agreements. The sellers filed certain counterclaims against Promis. In 1997,
Promis and the sellers reached a settlement of the dispute. The settlement
provided that commencing on April 7, 1998 Promis would pay additional cash to
the sellers

F-18
<PAGE>
PRI AUTOMATION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

I. CONTINGENT LIABILITY: (CONTINUED)
in an amount equal to the amount by which the market value of 59,889
exchangeable common shares, on each of the agreed-upon payment dates, is less
than $73.91 per common share. As part of the settlement, half the additional
cash consideration was payable on April 7, 1998, with the remaining half due in
20 quarterly installments commencing on July 7, 1998 through April 7, 2003.
Under the terms of the settlement agreement, the sellers are restricted as to
the number of shares of the Company's common stock which can be sold in any
quarter prior to April 7, 2003.

Since the payment of additional consideration is determined based on the
Company's share price at various future dates, any consideration in addition to
that paid to date will be recorded as a reduction in additional paid-in capital
of the Company as the amounts become determinable. The Company's contingent
liability as of January 2, 2000, calculated based on the market value of the
Company's common stock at January 2, 2000, is approximately $142,000.

The Company experienced net operating losses during fiscal years 1998 and
1999 and, therefore, believes sufficient uncertainty exists regarding the
realizability of the net deferred tax assets and accordingly has established a
full valuation allowance in fiscal 1999. The net increase in the valuation
allowance during 1998 and 1999 was $2,459,000 and $19,680,000, respectively.

J. INCOME TAXES: (CONTINUED)
At September 30, 1999, the Company had U.S. federal net operating losses
(NOLs) of $43,814,000, of which $19,868,000 is expected to be utilized in full
upon carryback and the remaining amount of $23,946,000 is available to offset
future taxable income. The Company has recorded a tax receivable related to the
NOL carryback claim which is classified in other current assets. Approximately
$8,343,000 of the NOL is attributable to the exercise of stock options for which
the tax benefit and related valuation allowance was recorded directly to
stockholders' equity. The U.S. federal net operating losses are available for
carryforward and expire in fiscal year 2020. The Company also has U.S. federal
credit carryforwards of $1,926,000 that begin to expire in fiscal year 2012. The
Company has available state net operating losses of $39,455,000 that expire in
fiscal year 2004 to fiscal year 2020 and state credit carryforwards of
$2,673,000 that expire beginning in fiscal year 2013. The Company also has
non-U.S. losses of $2,130,000 that expire beginning in fiscal year 2005, and
non-U.S. credits of $3,200,000 that begin to expire in fiscal year 2005.

K. FINANCING ARRANGEMENTS:

REVOLVING CREDIT

On June 16, 1998, the Company entered into a revolving credit facility
agreement with Chase Manhattan Bank (the "Bank"). The revolving credit facility
enables the Company to borrow up to $20,000,000 on an unsecured basis.
Outstanding revolving credit loans bear interest, at the Company's option, at
the 30, 60 or 90 day LIBOR rate plus a credit spread, or at the effective prime
rate. At September 30, 1999, the LIBOR borrowing rate would have been 6.50%. The
ability of the Company to effect borrowings under the revolving credit facility
is conditioned upon the meeting of certain financial criteria. The revolving
credit agreement expires on June 16, 2000. The Company had outstanding letters
of credit with the Bank of $1,875,000 at September 30, 1999, and therefore, the
available balance under this credit agreement was $18,125,000 at September 30,
1999. At September 30, 1999, the Company was not in compliance with certain of
the required covenants but has subsequently received a waiver from the Bank on
November 15, 1999 for the quarter ended September 30, 1999. The Company was in
default of the minimum consolidated net worth requirement, the minimum fixed
charge coverage ratio, and the minimum consolidated net income requirements of
the revolving credit agreement for the three months ended September 30, 1999.
The Company expects to seek future waivers as necessary from the Bank. However,
there can be no assurance that such waivers will be obtained.

Promis' operating line of credit of $2.9 million with the Bank of Nova
Scotia expired on April 30, 1999 and was not renewed. There were no borrowings
against this operating facility while in effect.

CAPITAL LEASE OBLIGATIONS

The Company holds certain property and equipment under capital leases. The
obligations under capital leases represent the present value of future minimum
lease payments and are secured by certain assets of the Company. The capital
lease obligations bear interest at rates of 7.0% to 9.9% per annum and expire at
various dates through July 2002 (see Note F).

L. DEFINED CONTRIBUTION PLANS:

Eligible employees can participate in the Company's 401(k) Savings and
Retirement Plan by making voluntary contributions to the plan in amounts up to
the statutory limit or 15% of their annual compensation. Currently, the Company
has elected to match a portion of the employee deferral up to

F-21
<PAGE>
PRI AUTOMATION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

L. DEFINED CONTRIBUTION PLANS: (CONTINUED)
certain prescribed limits, and these contributions vest at a rate of 20% per
year. Pursuant to the acquisition of Promis, certain eligible employees receive
Company matching contributions which vest 100% after one year. The Company's
contribution expense under these plans amounted to $780,000, $1,101,000, and
$1,118,000 for fiscal years 1997, 1998 and 1999, respectively. Employees of
Equipe were not eligible under this plan until after the acquisition (see
Note O).

Canadian employees are eligible to participate in the Registered Retirement
Savings Plan ("RRSP") which allows voluntary contributions up to the statutory
limit. The Company has elected to match a portion of the employee contributions,
up to a maximum of $5,000 per employee per year. These contributions are fully
vested when made. The Company's contribution expenses under the RRSP were
approximately $129,000, $148,000, and $172,000 in fiscal years 1997, 1998 and
1999, respectively.

M. SEGMENT REPORTING AND GEOGRAPHIC INFORMATION:

Effective for fiscal year 1999, the Company adopted SFAS No. 131,
"Disclosure about Segments of an Enterprise and Related Information." This
standard designates the Company's internal organization as used by management
for making operating decisions and assessing performance as the source of
business segments.

The Company operates in three primary segments, all within the semiconductor
manufacturing and OEM equipment supply industry, which serve both domestic and
international markets. These reportable operating segments consist of Factory
Automation Systems, Tool Automation Systems and MES and Other Systems. These
businesses are segregated into their respective reportable segments based on the
Company's management reporting structure and its method of internal resource
allocations. Additionally, the Company's product development processes and
customers were evaluated in determination of the segments.

The Factory Automation Systems segment provides automation products for
interbay, intrabay and lithography automation as well as integration and support
services to semiconductor manufacturers. The Tool Automation Systems segment
provides wafer-handling systems, software and services for process tool
equipment suppliers. The MES and Other Systems segment primarily provides
manufacturing execution system ("MES") software and advanced planning and
scheduling software to semiconductor manufacturers. This segment, however, does
not include all of the Company's software products, as material control software
("MCS") and tool connectivity software are components of the other segments.

The Company's operating segments have no significant intersegment revenues
and expenses, as all segments' revenues are generated from sales to unaffiliated
customers. External revenues and expenses are allocated between the applicable
segments. The Company's segments are evaluated on an operating profit basis, and
other income and expenses and income tax provisions or benefits are not
calculated for the specific segments. Any results of operations or assets not
specifically allocated to these segments are included in the Corporate and Other
category. The Corporate and Other category assets include all non-identifiable
assets, primarily cash and investments, deferred income taxes, and other current
and non-current assets. Activity related to strategic technology development,
corporate marketing, general corporate administrative expenses, merger costs and
special charges, other income and expenses and income taxes are included in the
Corporate and Other segment. Depreciation expense and expenditures for
long-lived assets by segment are not presented below as amounts are not used in
measuring

N. ACQUISITION OF PROMIS:

On March 2, 1999, the Company acquired Promis, a Canadian corporation, in a
transaction accounted for as a pooling of interests. Promis is a developer of
manufacturing execution systems ("MES") software solutions for semiconductor and
precision electronics manufacturers. In connection with the acquisition, the
Company issued 0.1353 exchangeable shares for each outstanding Promis share, or
an aggregate of 1,389,974 exchangeable shares. Each exchangeable share may be
exchanged at any time for one share of common stock of the Company. The Company
assumed options to purchase 270,336 shares of the Company's common stock and a
warrant to purchase 13,530 shares of common

stock, converted at the common stock exchange ratio, under this acquisition
agreement (see Note H). The consolidated financial statements of the Company for
periods prior to the acquisition have been restated to include the financial
position, results of operations and cash flows of Promis.

Prior to the acquisition, Promis prepared its financial statements based on
a December 31 fiscal year-end. Accordingly, Promis' results of operations,
statements of stockholders' equity and cash flows for the year ended
December 31, 1997 were combined with the Company's results of operations,
statements of stockholders' equity and cash flows for the year ended
September 30, 1997. The results of operations, statements of stockholders'
equity and cash flows for fiscal 1998 are for the twelve months ended
September 30, 1998 for both the Company and Promis. Promis' results of
operations for the three months ended December 31, 1997, including net revenue
of $6,457,000 and net income of $403,000, are included in the Company's
consolidated statements of operations, statements of stockholders' equity, and
cash flows for both the years ended September 30, 1998 and 1997. To conform
fiscal periods, an amount equal to Promis' net income and $33,000 of Promis'
additional paid-in capital from the exercise of stock options for the three
months ended December 31, 1997 were eliminated from the consolidated statement
of stockholders' equity for the year ended September 30, 1998. Additionally,
Promis' $50,000 increase in cash and cash equivalents for the three months ended
December 31, 1997 has been eliminated in the Company's condensed consolidated
statement of cash flows for the year ended September 30, 1998, because this
increase has been included in the beginning cash and cash equivalents at
October 1, 1997.

The following information presents certain statements of operations data of
the Company, after restatement from the Equipe acquisition, and Promis for the
period prior to the Promis acquisition. The Company made certain adjustments, as
shown below, to Promis' accounting policies related to software revenue
recognition under SOP 97-2, "Software Revenue Recognition," and to limit the
life of goodwill in a technology-related acquisition to no more than 10 years:

O. ACQUISITION OF EQUIPE:

On January 22, 1998, the Company acquired Equipe, a worldwide developer,
manufacturer, and supplier of wafer and substrate handling robots, pre-aligners
and controllers for semiconductor process tool manufacturers. The Company issued
4,088,016 shares of its common stock in exchange for all of the outstanding
stock of Equipe Technologies, Inc., using an exchange ratio of 0.760372 of one
share of the Company's common stock for each share of Equipe Technologies, Inc,
and the Company issued 36,000 and 240,000 shares of the Company's common stock
for the common stock of E-Machine, Inc. and Equipe Japan Ltd., respectively. In
addition, all outstanding Equipe stock options were converted,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

O. ACQUISITION OF EQUIPE: (CONTINUED)
at the common stock exchange ratio, into options to purchase the Company's
common stock. The business combination was accounted for as a
pooling-of-interests. The consolidated financial statements of the Company for
periods prior to the acquisition have been restated to include the financial
position, results of operations and cash flows of Equipe. Significant
intercompany transactions among the Equipe Combined Companies prior to the
period in which the business combination occurred have been eliminated from the
accompanying financial statements.

Prior to the acquisition, Equipe prepared its financial statements based on
a December 31 fiscal year-end. Accordingly, Equipe's results of operations,
statements of stockholders' equity and cash flows for the year ended
December 31, 1996 were combined with the Company's results of operations,
statements of stockholders' equity and cash flows for the year ended
September 30, 1996. The results of operations, statements of stockholders'
equity and cash flows for fiscal 1997 are for the twelve months ended
September 30, 1997 for both the Company and Equipe. Equipe's results of
operations for the three months ended December 31, 1996 (including revenues, net
income and distributions to shareholders of $6,906,000, $1,582,000 and
$5,287,000, respectively) are included in the Company's consolidated statements
of operations, statements of stockholders' equity and cash flows for both the
years ended September 30, 1997, as presented herein, and 1996. Therefore, an
amount equal to Equipe's net income and distributions to shareholders for the
three months ended December 31, 1996 was eliminated from the consolidated
statement of stockholders' equity for the year ended September 30, 1997.
Equipe's decrease in cash and cash equivalents for the three months ended
December 31, 1996 of $218,000 is included in the consolidated statement of cash
flows for both the years ended September 30, 1997, as presented herein, and
1996. Therefore, this amount was eliminated from the consolidated statement of
cash flows for the year ended September 30, 1997.

Equipe Technologies, Inc. and E-Machine, Inc. were S-corporations for income
tax purposes prior to the acquisition. Pro forma net income (loss) and net
income (loss) per common share, which give effect to adjustments that provide
for income taxes as if Equipe Technologies, Inc. and E-Machine, Inc. had been
treated as C-corporations for the period presented, have been presented on the
consolidated statements of operations. The pro forma information is shown for
comparative purposes only.

The following information presents certain statements of operations data of
the Company and Equipe for the period prior to the Equipe acquisition. The

P. ACQUISITION OF CHIPTRONIX:

On May 19, 1998, the Company acquired Chiptronix, a Switzerland corporation,
for aggregate non-cash consideration of 105,000 shares of the Company's common
stock. Chiptronix was the European distributor of Equipe products. The business
combination was accounted for as a pooling of

P. ACQUISITION OF CHIPTRONIX: (CONTINUED)
interests. However, as the financial position and results of operations of
Chiptronix are immaterial to the financial position and results of operations of
the Company on a consolidated basis, no prior period financial amounts have been
restated. In accordance with this business combination, the Company has acquired
the net liabilities of Chiptronix, in the amount of $1,543,000, including net
cash assumed of $246,000. Additionally, the Company acquired Chiptronix'
retained deficit of $1,556,000 as of March 29, 1998 and this amount is included
in the changes to stockholders' equity for the year ended September 30, 1998.
The results of operations of Chiptronix for the six months ended September 30,
1998 have been included in the accompanying consolidated financial statements of
the Company.

Q. ACQUISITION OF INTERVAL LOGIC CORPORATION:

On October 29, 1997 the Company acquired ILC, a California corporation, for
aggregate non-cash consideration of 111,258 shares of the Company's common
stock. In addition, the Company assumed options to purchase an aggregate of
199,170 shares of the Company's common stock. ILC was formed in 1995 to develop
advanced, high-performance planning and scheduling software solutions for the
semiconductor industry. The value of the transaction was $8,523,000, including
approximately $600,000 of expenses related to the acquisition. $424,000 of net
liabilities of ILC were acquired under this transaction. The Company accounted
for the transaction as a purchase. Pro forma information for the previous period
has been omitted because the effect of restatement would be immaterial.

At the time of the acquisition, the purchase price was allocated to the
tangible and intangible assets of ILC. Management is aware that it is
responsible for estimating the fair value of purchased in-process research and
development. The value assigned to the intangible assets, primarily the acquired
technology, was based on the fair market value using a risk-adjusted discounted
cash flow approach. ILC's sole product at the time of the acquisition was the
Leverage product, which was under development. ILC had no product revenues
during its prior existence and was a development stage enterprise. Specifically,
the purchased technology was evaluated through extensive interviews and analysis
of data concerning the state of the technology and needed developments. This
evaluation of underlying technology acquired considered the inherent
difficulties and uncertainties in completing the development, and thereby
achieving technological feasibility, and the risks related to the viability of
and potential changes in future target markets. The significant assumptions that
affected the valuation of ILC concerned potential revenue and cost of
completion, as well as the timing of the product release. In addition, the
selection of an appropriate discount rate was a major factor in the valuation
analysis.

The revenue assumptions for this product were a key variable in the
Company's valuation analysis. The Company developed revenue projections based on
management's expected release date of March 1999 for the beta version of the
Leverage product. Given that ILC had no historical revenue to rely on as a
guide, the Company based its projections on revenues from a population of
comparable companies. The revenue growth rates projected for the Leverage
product were comparable to the 3-year cumulative average growth rate for the
comparable companies. The costs of completion assumptions for the Leverage
product were a second key variable in the Company's valuation analysis. These
assumptions were based on detailed cost analysis provided by the head of
research and development for ILC, and included assumptions regarding completion
dates for development milestones. The total development effort was estimated to
take approximately 225 engineering man-months at a cost of approximately
$2,800,000. This project included completion of the software requirement
definition, data integration and validation, completion of the graphics user
interface, development of alpha and beta versions for customer testing, and
integration and adaptation with

PRI AUTOMATION, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Q. ACQUISITION OF INTERVAL LOGIC CORPORATION: (CONTINUED)
customer systems. The significant further investments in development required to
meet expected customer requirements were substantially completed in the third
quarter of fiscal 1999. The actual development costs have approximated the cost
estimates used in the valuation model.

The acquired technology had not reached technological feasibility at the
time of the acquisition. The Company defines technological feasibility as the
point at which a working model is functioning to designed specifications and has
been placed at a beta test site. The Leverage product was first released to a
beta test site in March 1999. In addition, the technology had no alternative
future use to the Company in other research and development projects or
otherwise. Accordingly, the acquired technology was expensed as in-process
research and development. Based on the methodology described above, the Company
assigned a fair value of $8,417,000 to the technology.

R. ACQUISITION OF MASE:

Effective October 2, 1997, prior to the acquisition of Promis by the
Company, Promis purchased the net assets of MASE Systems, Inc. ("MASE") of San
Jose, California for $1,533,000 in cash. The Company acccounted for the
transaction as a purchase. The net assets of MASE acquired included $170,000 of

$1,337,000 in intellectual property. Pro forma information for the previous

results of operations would be immaterial.

S. MERGER COSTS AND SPECIAL CHARGES:

For the year ended September 30, 1999, the Company recorded special charges
of $650,000 in the first quarter. These charges represent provisions for
severance compensation relating to the termination of 62 personnel. The
personnel reductions included 40 in manufacturing and customer support, eight in
engineering, and 14 in selling, general and administrative functions. The
reduction in force occurred in response to the continued downturn in the
semiconductor equipment industry. As of September 30, 1999, all of the severance
compensation had been paid.

For the year ended September 30, 1999, the Company, in the second quarter,
recorded merger costs of $3,950,000 related to the acquisition of Promis,
primarily consisting of legal, accounting and investment banking fees. As of
September 30, 1999, all of these merger costs had been paid. Additionally,
during the second quarter the Company recorded special charges of $1,850,000.
The special charges consisted of $1,406,000 for compensation-related costs for
five management personnel in the selling, general, and administrative functions
to satisfy existing contractual obligations related to the acquired companies;
$196,000 of costs associated with the reductions of leased facilities; and
$248,000 for other legal issues. In the fourth fiscal quarter, the Company
recognized a special credit of $75,000 to adjust the estimated costs to reflect
actual costs. At January 2, 2000, $272,000 of these charges remained in accrued
expenses and are expected to be paid by December 2000.

In connection with the acquisition of Equipe, direct acquisition costs of
$4,490,000 for legal, investment banking and accounting fees were recorded in
fiscal 1998. Approximately $35,000 remained in accrued expenses at January 2,
2000 in connection with these direct acquisition costs and are expected to be
paid by the end of the second fiscal quarter of 2000.

Additionally, during the second, third and fourth quarters of fiscal 1998,
the Company recorded restructuring and other special charges of $5,601,000 in
response to market conditions and to integrate the Equipe operations. The
special charges included provisions for severance compensation of

S. MERGER COSTS AND SPECIAL CHARGES: (CONTINUED)
$1,910,000 resulting from terminations of approximately 244 personnel completed
in 1998. The personnel reductions consisted of 123 in manufacturing and customer
support, 65 in engineering and 56 in sales, general and administrative
functions. In addition, the special charges included costs of $2,943,000
relating to reductions of leased facilities space and a non-cash write-down of
specialized demonstration equipment for a particular customer of $748,000 and
other assets that are not usable elsewhere. Of the total $4,853,000 severance
and lease reduction charges recorded in fiscal 1998, all of these special
charges had been paid as of September 30, 1999.

During the years ended September 30, 1998 and 1999, options to purchase
3,545,670 and 3,759,387 shares of common stock were outstanding but were not
included in the computation of diluted net loss per common share because the
Company was in a loss position and, the inclusion of such shares would be
anti-dilutive. Options to purchase 55,281 shares of common stock were
outstanding for fiscal year 1997 but were not included in the computation of
diluted net loss per common share because the options' exercise prices were
greater than the average market price of the common shares, and therefore, would
be anti-dilutive under the treasury stock method.

Options to purchase 768,150 shares of common stock were outstanding as of
January 2, 2000 but were not included in the computation of diluted net income
per common share because the options' exercise prices were greater than the
average market price of the common shares, and therefore, would be anti-dilutive
under the treasury stock method. Options to purchase 3,391,906 shares of common
stock were outstanding as of December 27, 1998, but were not included in the
computation of diluted net loss per common share because the Company was in a
loss position, and the inclusion of such shares would be anti-dilutive.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Article 6C of PRI's Restated Articles of Organization provides that PRI
(with certain exceptions) will indemnify and hold harmless to the fullest extent
authorized by the Massachusetts Business Corporation Law each person who was or
is made a party or is threatened to be made a party to or is otherwise involved
in any action, suit or proceeding, whether civil, criminal, administrative,
investigative or otherwise (hereinafter a "Proceeding"), by reason of the fact
that he or she is or was (a) a director of PRI, (b) an officer of PRI elected or
appointed by the stockholders or the Board of Directors, or (c) serving, at the
request of PRI as evidenced by a vote of the Board of Directors prior to the
occurrence of the event to which the indemnification relates, as a director,
officer, employee or other agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to an
employee benefit plan (such persons described in (a), (b) and (c) are sometimes
hereinafter referred to as an "Indemnitee") against all expense, liability, and
loss reasonably incurred by any such Indemnitee in connection therewith. PRI may
also, to the extent authorized by the Board of Directors, grant rights to
indemnification, and to an advancement of expenses, to any employee or agent of
PRI. Notwithstanding the foregoing, if Massachusetts Business Corporation Law
requires, an advancement of expenses incurred by an Indemnitee will be made only
upon delivery to PRI of an undertaking, by or on behalf of such Indemnitee, to
repay all amounts so advanced if it shall ultimately be determined by final
judicial decision from which there is not further right to appeal that such
Indemnitee is not entitled to be indemnified for such expenses.

The rights under Article 6C may not be amended or terminated so as to
adversely affect an individual's rights with respect to the period prior to such
amendment without the consent of the person entitled to the indemnification
(unless otherwise required by the Massachusetts Business Corporation Law).

Section 67 of Chapter 156B of the Massachusetts Business Corporation Law
authorizes a corporation to indemnify its directors, officers, employees and
other agents unless such person shall have been adjudicated in any proceeding
not to have acted in good faith in the reasonable belief that

II-1
<PAGE>
his action was in the best interests of the Corporation or to the extent that
such matter relates to service with respect to an employee benefit plan, in the
best interests of the participants of such employee benefit plan.

The effect of these provisions would be to authorize such indemnification by
PRI for liabilities arising out of the Securities Act of 1933 (the "Securities
Act").

ITEM 17. UNDERTAKINGS.

The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's

II-2
<PAGE>
annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in the Registration Statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial BONA FIDE offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
