NOTE E --  NET INCOME (LOSS) PER SHARE

        Basic net income (loss) per share is calculated using the weighted
average number of shares of common stock outstanding during the period. Diluted
net income per share includes the assumed exercise of employee stock options.
The assumed conversion of the convertible subordinated notes to common shares
was excluded from diluted net income (loss) per share because its effect is
antidilutive for all periods. Options outstanding during the three and six month
periods ended December 31, 1998 were excluded from the computation of diluted
net loss per share because the effect in periods with a net loss would have been
antidilutive. The shares potentially issuable under the third party put option
transactions have been excluded from the computation of net income per share
because the effect would have been antidilutive.

NOTE G -- RESTRUCTURING

        During the Company's first fiscal 1997 quarter ended September 30, 1996,
the Company projected and announced that revenues would be lower than previous
quarters due to a projected 20% general market decline. The Company's revenues
during that quarter fell to $299.2 million, a decrease of 24% from the prior
quarter. The Company



                                       8
   9

assessed that market conditions would remain depressed and, therefore, that its
revenues would continue to be adversely affected. Accordingly, and as announced
on August 26, 1996, the Company organizationally restructured its business units
into a more centralized structure and cut its workforce by approximately 11%.

        The Company's quarterly revenue would eventually decline to $233.3
million in the March 1997 quarter, 40% lower than the peak reached in the
quarter ended June 1996. Subsequently, in the latter part of calendar 1997, the
industry rebounded quickly and entered into what eventually became a short-lived
upturn cycle. During the June 1997 quarter, the Company's revenues grew back to
$282.6 million and reached $292.1 million by the December 1997 quarter. However,
the Company's outlook in late January 1998 was that the industry was again
entering into a steep downturn brought on by depressed DRAM pricing and the
Asian financial crisis. The Company therefore announced a further set of
restructuring activities in a news release on February 12, 1998. At that time,
the Company's assessment related to industry conditions was that its revenues
for the March and June 1998 quarters would decline by approximately 20%. The
Company's restructuring plans aligned its cost structure to this level of
revenues by exiting part of its Chemical Vapor Deposition ("CVD") business and
all of its Flat Panel Display ("FPD") business, consolidating its manufacturing
facilities and substantially reducing its remaining infrastructure and
workforce. The Company's actual June 1998 revenues were in line with those
expectations; however, by the mid-June 1998 time-frame the industry conditions
further deteriorated and the outlook for future quarters significantly worsened.
The Company projected revenues to drop to a run rate of approximately $180
million per quarter and determined it needed once more to reduce its cost
structure in line with the projected reductions in revenue. Accordingly, another
separate restructuring plan was developed and announced in June 1998. As a
result of the restructurings in fiscal 1998, the Company reduced its global
workforce by approximately 28% and exited the remainder of its CVD operations.

        The Company's revenue outlook in June 1998 was based on the Company's
projection that the worldwide wafer fabrication industry would deteriorate from
a quarterly revenue amount of $4.2 billion to $3.2 billion, or a 25% decline.

        The semiconductor equipment market contracted beyond what was
anticipated, to quarterly revenues of $2.6 billion. The Company's shortfall of
revenues during the September 1998 quarter declined in line with the industry as
a whole, and resulted in lower than anticipated revenues, falling to $142.2
million. At that point in time, the Company projected that its quarterly
revenues would remain closer to the $140-$150 million levels for at least the
next several quarters. This necessitated another restructuring plan and further
cost reductions via employee terminations, facilities consolidation and a
contraction of operating activities, all of which resulted in the additional
write-down of plant related assets. This plan was announced and publicly
communicated on November 12, 1998. As a result of the fiscal 1999 restructuring,
the Company reduced further its global workforce by approximately 15%.

        Severance and Benefits relates to the salary and fringe benefit expense
for the involuntarily terminated employees representing approximately 15% of the
global workforce. Prior to the date of the financial statements, management,
with the proper level of authority, approved and committed the Company to a plan
of termination and determined the benefits the employees being terminated would
receive. Prior to the financial statement date, the expected termination
benefits were communicated to employees in enough detail that they could
determine their type and amount of benefit. The termination of employees
occurred shortly after the plan of restructuring was finalized.

        Lease Payments on Vacated Facilities relates to 24 months of rent and
common area maintenance expense for the vacated facilities. The Company also
estimated, given the then-current real estate market conditions, that it would
take approximately 24 months to sub-lease its excess facilities in Fremont,
California.

        The Company wrote-off all leasehold improvements for the excess
facilities, computer equipment, furniture and fixtures related to the
involuntarily terminated employees, and other assets deemed to have no future
use as a result of the restructuring.

        Credit on Returned Equipment relates to the charge associated with the
requirement by certain of the Company's customers to return their previously
purchased CVD systems and spare parts.

        Severance and Benefits relates to the salary and fringe benefit expense
for the involuntarily terminated employees of the CVD and FPD operations which
were exited, the shutdown of the Wilmington, Massachusetts manufacturing
facility, and the employees impacted by the overall across-the-board reduction
of the employee base. Prior to the date of the financial statements, management,
with the proper level of authority, approved and committed the Company to a plan
of termination and determined the benefits the employees being terminated would
receive. Prior to the financial statement date, the expected termination
benefits were communicated to employees in enough detail that they could
determine their type and amount of benefit. The restructuring plans resulted in
the Company reducing its global workforce by approximately 28%. The termination
of employees occurred shortly after the plan of restructuring was finalized.

        Lease Payments on Vacated Facilities which was included in the
restructuring charge related to remaining rent and common area maintenance on
the closed Wilmington, Massachusetts manufacturing facility. The Company also
estimated, given the then-current real estate market conditions, that it would
take approximately 24 months to sub-lease its excess facilities in Fremont,
California. The Company, therefore, included 24 months of rent and common area
maintenance expense related to excess facilities in its restructuring charge.
Subsequently, the Company has subleased some of its excess facilities.

        The Company wrote-off all fixed assets relating to the operations which
were exited, leasehold improvements for the excess facilities, computer
equipment, furniture and fixtures related to the involuntarily terminated
employees, and other assets deemed to have no future use as a result of the
restructuring.

        The inventory write-off which was included in the restructuring charge
related to inventory from the operations which were exited. The inventory
write-off included raw material on hand and inventory purchased under
non-cancelable commitments from suppliers, spare parts, work-in-process and
finished goods related to the products from the exited operations.

        Credit on Returned Equipment relates to the charge associated with the
requirement by certain of the Company's customers to return their



                                       11

previously purchased CVD systems and spare parts. During fiscal 1999, the
Company recorded an adjustment to the restructuring reserve of $1.5 million for
the recovery of a previously written off machine.

        Other Exit Costs of $5.7 million relates to the net book value of
licensing and manufacturing agreements related to the restructured operations.

        Severance and Benefits relates to the salary and fringe benefit expense

of the global workforce. Prior to the date of the financial statements,
management, with the proper level of authority, approved and committed the
Company to a plan of termination and determined the benefits the employees being
terminated would receive. Prior to the financial statement date, the expected
termination benefits were communicated to employees in enough detail that they
could determine their type and amount of benefit. The termination of employees
occurred shortly after the plan of restructuring was finalized. During fiscal
1998, the Company revised its estimate relating to severance and benefits and
transferred the excess balance of remaining lease payments on vacated facilities
to severance and benefits.

        Lease Payments on Vacated Facilities relates to remaining rent and
common area maintenance expense for the vacated facilities.

        The Company wrote-off all leasehold improvements for the excess
facilities, computer equipment, furniture and fixtures related to the
involuntarily terminated employees, and other assets deemed to have no future
use as a result of the restructuring.

NOTE H --        CHANGE IN FUNCTIONAL CURRENCY

        The Company has determined that the functional currency of its European
and Asia Pacific foreign subsidiaries is no longer the U.S. dollar but the
individual subsidiary's local currency. The following



                                       12
   13

are the reasons for the Company's change in functional currency: the Company's
European and Asia Pacific foreign subsidiaries primarily generate and expend
cash in their local currency; their labor and services are primarily in local
currency (workforce is paid in local currency); their individual assets and
liabilities are primarily dominated in the local foreign currency and do not
materially impact the Company's cash flows and there is an active local sales
market for the foreign subsidiaries products and services. The European and Asia
Pacific foreign subsidiaries are currently less dependent on US corporate office
with their daily operations. In addition, the European community adopted a new
Single European Currency, the Euro, which required implementation of that
currency as of January 1, 1999 and transition through January 1, 2002. All
balance sheet accounts are translated at the current exchange rate, and income
statement accounts are translated at an average rate for the period. The
resulting translation adjustments are recorded as currency translation
adjustment, which is a component of accumulated other comprehensive loss.
Previously, some balance sheet accounts were translated at an historic rate and
translation adjustments were made directly to the statement of operations. The
impact of the change in functional currency was not material to the Company's
financial statements.

NOTE I -- LITIGATION

        See Part II, item 1 for discussion of litigation.

NOTE J -- PURCHASED TECHNOLOGY FOR RESEARCH and DEVELOPMENT

        During the second quarter of fiscal 2000, the Company purchased
intellectual property rights related to the semiconductor equipment industry
from Oliver Design, Inc. ("Oliver"). The Company recognized an expense for the
purchase of research development technology of approximately $7.5 million and
capitalized $1.5 million related to patents, which will be amortized ratably
over five years. The technology is being used in a single discrete next
generation post-CMP wafer cleaning product development project and has no future
alternative use. The Company may make up to $2.0 million in additional license
payments to Oliver based on product sales in the event it is successful in
commercialization of the technology.

NOTE K -- SUBSEQUENT EVENT

        During January 2000, the Company's Board of Directors approved a
three-for-one split of the company's outstanding common stock, subject to
stockholders approval of an increase in the Company's authorized common stock to
400 million shares, at a special meeting scheduled for March 6, 2000. If the
required approval is obtained, the Company expects the three-to-one stock split
to be effective March 7, 2000. Stockholders of record at the close of business
on the effective date will be entitled to two additional shares of common stock
for each share of the Company's common stock held on that date. The distribution
date for the stock split will be March 16, 2000. On or about that date, the
Company's transfer agent will mail the new shares to stockholders. The Company
expects that its outstanding common stock will begin to trade on a post-split
basis on March 17, 2000.

ITEM 2.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations

        With the exception of historical facts, the statements contained in this
discussion are forward-looking statements within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934, and are subject to the Safe Harbor provisions created by that statute.
Such forward-looking statements include, but are not limited to, statements that
relate to our future revenue, product development, demand, acceptance and market
share, competitiveness, royalty income, gross margins, levels of research and
development and operating expenses, our management's plans and objectives for
our current and future operations, the effects of our on-going reorganization
and consolidation of operations and facilities, our ability to complete
reorganizations or consolidations on time or within anticipated costs, and the
sufficiency of financial resources to support future operations and capital
expenditures. Such statements are based on current expectations and are subject
to risks, uncertainties, and changes in condition, significance, value and
effect, including those discussed below under the heading Risk Factors, and
other documents we may file from time to time with the Securities and Exchange
Commission, specifically our last filed Annual Report on Form 10-K for the
fiscal year ended June 30, 1999. Such risks, uncertainties and changes in
condition, significance, value and effect could cause our actual results to
differ materially from those expressed herein and in ways not readily
foreseeable. Readers are cautioned not to place undue reliance on these
forward-looking statements, which speak only as of the date hereof and of
information currently and reasonably known. We undertake no obligation to
release any revisions to these forward-looking statements which may be made to
reflect events or circumstances which occur after the date hereof or to reflect
the occurrence or effect of anticipated or unanticipated events. This discussion
should be read in conjunction with the Condensed Consolidated Financial
Statements and Notes presented thereto on pages 3 to 13 of this Form 10-Q for a
full understanding of our financial position and results of operations for the
three and six month periods ended December 26, 1999.

RESULTS OF OPERATIONS

Total Revenue

        Our total revenue for both the three and six month periods ended
December 26, 1999 increased 103.4% and 86.6%, respectively, compared to the
respective periods of the prior fiscal year. We experienced increased revenues
for all of our product lines during both the three and six month periods of
fiscal 2000 compared to the year-ago periods. Our product sales continued to
shift from our single-chamber systems to our multi-chamber cluster systems. Our
increased revenue in AllianceTM cluster system, which utilizes from one to four
chambers each, was the major contributor to our higher total revenue for both
three and six month periods ended December 26, 1999 compared to the year ago
periods.

which was brought on by increased sales and profitability of semiconductor
manufacturers. We anticipate greater demand for our systems, as our customers
continue to add capacity in their most advanced lines, and migrate to new lines
and materials such as copper and the new interconnect processes required to
implement them. We expect our net revenues for the next six months to be higher
than first half of fiscal year 2000. During calendar 1998, the global
semiconductor industry experienced a slowdown. Consequently depressed DRAM
pricing, production overcapacity as well as uncertainty in the worldwide
financial markets brought on a slowdown in equipment demand which unfavorably
impacted our sales for both the September and December quarters of calendar
1998.

Gross Margin

        Our gross margin percentage increased to 43.5% and 42.7%, respectively,
in the three and six month periods ended December 26, 1999, compared with 33.2%
and 34.2%, respectively, for the year-ago periods. The increase in our gross
margin percentage is due in large part to material cost reductions and higher
economy of scale due to greater volumes. We anticipate that our gross margins
will improve further by the end of fiscal 2000.

Research and Development

        Research and development ("R&D") expenses for the three and six month
periods ended December 26, 1999 were 18.5% and 15.1% higher than the year-ago
periods, respectively. However, as a percentage of revenue, R&D expenses were
14.0% and 15.0% of total revenue for the three and six month periods of fiscal
2000, respectively, compared with 24.0% and 24.3% for the three and six month
periods of fiscal 1999. The increase in R&D expenses is a result of our
continued investments in strategic R&D programs and initiatives in etch, CMP and
post-CMP wafer cleaning products. We believe that in order to remain
competitive, we must continue to invest substantially in R&D.

Selling, General and Administrative

        Selling, general and administrative ("SG&A") expenses increased by 1.1%
for the three month period ended December 26, 1999 when compared to the year-ago
period. SG&A expenses for the six month period ended December 26, 1999 were 8.7%
lower than the year-ago period. As a percentage of revenue, SG&A expenses for
the three and six month periods ended December 26, 1999 were 13.2% and 13.7%,
respectively, of total revenue compared to 26.5% and 28.0%, respectively, of
total revenue for the year-ago periods. The decrease in SG&A expenses for the
six month period ended December 26, 1999,



                                       15
   16

when compared to the prior year period is a result of our downsizing activities
in both fiscal 1998 and 1999 and our continued focus on improving efficiencies.

Purchased Technology for R&D

        During the second quarter of fiscal 2000, we purchased intellectual
property rights related to semiconductor equipment from "Oliver". We recognized
an expense for the purchase of research development technology of approximately
$7.5 million and capitalized $1.5 million related to patents which will be
amortized ratably over five years. The technology is being used in a single
discrete next generation post-CMP wafer cleaning product development project and
has no future alternative use. We may make up to $2.0 million in additional
license payments to Oliver based on product sales in the event we are successful
in commercializing this technology.

Restructuring Charge

        Our overall outlook in late January 1998 was that the industry had
entered into a steep downturn brought on by depressed DRAM pricing and the Asian
financial crisis. We therefore announced a set of restructuring activities in a
news release on February 12, 1998. At that time, our assessment related to
industry conditions was that our revenues for the March and June 1998 quarters
would decline by approximately 20%. Our restructuring plans aligned our cost
structure to a lower level of revenues by exiting part of our CVD business and
our FPD business, consolidating our manufacturing facilities and substantially
reducing our remaining infrastructure and workforce. Our actual June 1998
revenues were in line with those expectations; however, by the mid-June 1998
time-frame the industry conditions further deteriorated and the outlook for
future quarters significantly worsened. We projected revenues to decrease to a
run-rate of approximately $180 million per quarter and determined that, once
more, reductions of our cost structure were required to align with the projected
reductions in revenue. Accordingly, another separate restructuring plan was
developed and announced in June 1998. During fiscal 1998, we incurred a total
restructuring charge of $148.9 million relating to severance and benefits, lease
payments on vacated facilities, the write-off of fixed assets, excess and
obsolete inventory, returned equipment credits and other exit costs. As a result
of the fiscal 1998 restructurings, we reduced our global workforce by
approximately 28%. During fiscal 1999, we recorded an adjustment to the
restructuring reserve of $1.5 million for the recovery of a previously
written-off machine. At December 26, 1999, a total of $22.7 million of
restructuring-related accruals remained on our balance sheet, of which $9.9
million, $11.0 million and $1.8 million, respectively, relates to future
severance and benefit costs, lease payments, and returned equipment credits.
There will be further charges against the restructuring reserves in fiscal 2000,
as we complete the restructuring programs.

    During the quarter ended September 30, 1998, the semiconductor equipment
market contracted beyond the anticipated $3.2 billion revenue level to $2.6
billion, according to Dataquest. Our shortfall of revenues during the September
1998 quarter was in line with the industry as a whole, and resulted in our
revenues falling to $142.2 million for the quarter ended September 30, 1998. At
that point in time, we projected that our quarterly revenues would remain closer
to the $140-$150 million levels for at least the next several quarters. This
necessitated another restructuring plan and further cost reductions through
employee terminations, facilities consolidation and a contraction of operating
activities, and the write-off of vacated plant related assets. This plan was
announced and publicly communicated on November 12, 1998. During the second
quarter of fiscal 1999, we recorded a restructuring charge of $53.4 million,
relating to severance compensation and benefits for involuntarily terminated
employees worldwide (representing approximately 15% of the global workforce),
lease payments on abandoned facilities, the write-off of related leasehold
improvements and fixed assets and returned equipment credits issued to certain
customers. At December 26, 1999, $7.9 million of this charge remains accrued on
our consolidated balance sheet to cover continuing obligations. There will be
further charges against this restructuring reserve in fiscal 2000, as we
complete the restructuring program.

        Below is a table summarizing restructuring activity relating to the
fiscal 1999 restructuring:

        We have carried-out, and continue to carry-out, our restructuring
activities according to our original plans and timeline and we believe that the
anticipated cost reductions did not vary materially from our original
expectations. We intend to operate at levels of spending that are consistent
with our ability to generate revenues, therefore our spending levels may
increase or decrease depending upon our assessment of our current needs. We do
not believe that our decision to exit the CVD and FPD business will have a
material impact on our ability to generate future revenue growth.

Tax Expenses

        Our second fiscal quarter income tax provision was 14% of profits, in
accordance with a revised estimated effective tax rate of 13% for the fiscal
year ending June 25, 2000. This rate reflects the benefit of net operating
losses and research tax credits carried over from prior periods. We expect to
increase the effective income tax rate to approximately 30% in fiscal year 2001,
based on our current revenue and profit outlook for that period.

Transition to Single European Currency

        During fiscal 1999, we established a team to address issues raised by
the introduction of the Single European Currency ("Euro") for initial
implementation as of January 1, 1999, and through the transition period to
January 1, 2002. We met all related legal requirements by January 1, 1999, and
we expect to meet all legal requirements through the transition period. We do
not expect the cost of any related system modifications to be material and do
not currently expect that the introduction and use of the Euro will materially
affect our foreign exchange and hedging activities, or will result in any
material increase in transaction costs. We will continue to evaluate the impact
over time of the introduction of the Euro; however, based on currently available
information our management does not believe that the introduction of the Euro
has or will have a material adverse impact on our financial condition or results
of our operations.

Year 2000 Issues

        The Year 2000 compliance issue (in which systems do not properly
recognize date-sensitive information when the year changes from 1999 to 2000)
creates risks for us: if internal data management, accounting and/or
manufacturing or operational software and systems do not adequately or
accurately process or manage day or date information beyond the year 1999, there
could be an adverse impact on our operations. To address the issue, we assembled
in fiscal 1999 a task force to review and assess internal software, data
management, accounting, and manufacturing and operational systems to ensure that
they do not malfunction as a result of the Year 2000 date transition.

        Our next-generation enterprise resource planning and information system
will replace many of the system operations currently being performed by existing
internal system software. Implementation of this next-generation system is now
scheduled for completion during the first half of calendar 2000, and we have
received assurances that it will be Year 2000-compliant. Our existing internal
system encompassing core manufacturing, service, sales, inventory and warranty
operations, which will be replaced by the next-generation



                                       18
   19

system, is currently Year 2000-compliant and can continue to support our
significant operational systems, as needed.

        With respect to compliance of our products we supply to our customers,
we adhere to Year 2000 test case scenarios established by SEMATECH, an industry
group consisting of U.S. semiconductor manufacturers. Our compliance efforts,
and review and identification of corrective measures and contingency planning
(where necessary), are substantially complete. The application systems and
software of a significant number of our products currently supplied to our
customers are Year 2000-compliant, with the remainder expected to be so by the
end of the second quarter of fiscal 2000. With respect to certain of our
products already installed in the field, we have determined that in most
instances where the application systems and software are not Year
2000-compliant, there is either no appreciable effect or the effect during the
product's operation is limited to certain aspects of the product's ability to
report data concerning its operational parameters. However, the product's
operation, manufacturing capabilities or quality are not affected. We are in the
process of identifying and offering to our customers product upgrades with the
goal of resolving all material programs and systems prior to the Year 2000 date
transition. In this regard, we are incurring, and will continue to incur
throughout fiscal 2000, various costs to provide customer support regarding Year
2000 issues. Through the end of the second quarter of fiscal 2000, these costs
have totaled approximately $5.0 million.

        Our failure to ensure, at all or in a timely or reasonable manner, that
our products are Year 2000-compliant may cause disruption in the ability of our
customers to derive expected productivity from those products or to integrate
the products fully and functionally into certain automated manufacturing
environments.

        To date, we have experienced no material Year 2000 issues, and we expect
minimal future Year 2000 issues based on the performance to date of internal
systems that we use and the products we supply to our customers.

LIQUIDITY AND CAPITAL RESOURCES

        As of December 26, 1999, we had $387.7 million in cash, cash
equivalents, short-term investments and restricted cash, compared with $372.1
million at June 30, 1999. We have a total of $100.0 million available under a
syndicated bank line of credit which is due to expire in April 2001. Borrowings
are subject to our compliance with financial and other covenants set forth in
the credit documents. The syndicated bank line bears interest at rates ranging
from 0.55% to 1.25% over London Interbank Offered Rate ("LIBOR"). At December
26, 1999, we were in compliance with all our financial and other covenants.

        Net cash provided by operating activities was $39.0 million for the six
months ended December 26, 1999. This primarily resulted from net income before
non-cash charges of $84.2 million, increases in accounts payable and accrued
liabilities offset by increases in accounts receivable, inventory and prepaid
expenses. Cash used in investing activities was $45.5 million, which was
primarily from the net purchase of short-term investments of $21.6 million and
net capital expenditures of $20.9 million. Net cash provided by financing



                                       19
   20

activities was $0.4 million. We made principal payments on long-term debt and
capital lease obligations of $23.3 million offset by proceeds from the issuance
of long-term debt of $8.7 million. We purchased $5.1 million of common stock and
reissued $13.5 million of our treasury stock through our employee option and
stock purchase programs. Net proceeds from the issuance of our common stock
generated $13.3 million. Cash payments relating to our restructurings were
approximately $5.4 million.

        Given the cyclical nature of the semiconductor equipment industry, we
believe that maintenance of sufficient liquidity reserves is important to ensure
our ability to maintain levels of investment in R&D and capital infrastructure
through ensuing business cycles. Based upon our current business outlook, our
cash, cash equivalents, short-term investments, restricted cash and available
lines of credit at December 26, 1999 are expected to be sufficient to support
our currently anticipated levels of operations and capital expenditures through
at least the next 12 months.

RISK FACTORS

        OUR QUARTERLY REVENUES AND OPERATING RESULTS ARE UNPREDICTABLE

        Our revenues and operating results may fluctuate significantly from
quarter to quarter due to a number of factors, not all of which are in our
control. These factors include:

    -   economic conditions in the semiconductor industry generally, and the
        equipment industry specifically;

    -   customer capacity requirements;

    -   the size and timing of orders from customers;

    -   customer cancellations or delays in our shipments;

    -   our ability in a timely manner to develop, introduce and market new,
        enhanced and competitive products;

    -   our competitors' introduction of new products;

    -   legal or technical challenges to our products and technology;

    -   changes in average selling prices and product mix; and

    -   exchange rate fluctuations.

        We base our expense levels in part on our expectations of future
revenues. If revenue levels in a particular quarter do not meet our
expectations, our operating results are adversely affected.

        We derive our revenue primarily from the sale of a relatively small
number of high-priced systems. Our systems can range in price from approximately
$150,000 to over $4 million per unit. Our operating results for a quarter may
suffer substantially if:

    -   we sell fewer systems than we anticipate in any quarter;

    -   we do not receive anticipated orders in time to enable actual shipment
        during that quarter;

    -   one or more customers delay or cancel anticipated shipments; or

    -   shipments are delayed by procurement shortages or manufacturing
        difficulties.



                                       20
   21

        Further, because of our continuing consolidation of manufacturing
operations and capacity at our Fremont, California facility, natural, physical,
logistical or other events or disruptions affecting this facility (including
labor disruptions) could adversely impact our financial performance.

        WE MAY EXPERIENCE DIFFICULTY IMPLEMENTING OUR NEW ENTERPRISE RESOURCE

        Our next-generation enterprise resource planning and information system
will replace many of the system operations currently being performed by existing
internal system software, including core manufacturing, service, sales,
shipping, inventory and warranty operations and other significant operational
systems. Implementation of this next-generation system is now scheduled for
completion during the first half of calendar 2000. Delays in our ability to
implement or transition to this new planning and information system, or
disruptions in our internal operations or systems caused by the transition or
the need to free up additional support and resources in order to ensure our
timely implementation of or transition to this new planning and information
system, could temporarily disrupt certain of our operations. This could include,
a temporary delay in our ability to manufacture and ship equipment and/or spare
parts to our customers, which could cause a near-term short fall in quarterly
operating results, including revenues and earnings.

        THE SEMICONDUCTOR EQUIPMENT INDUSTRY IS VOLATILE, WHICH AFFECTS OUR
        REVENUES AND FINANCIAL RESULTS

        Our business depends on the capital equipment expenditures of
semiconductor manufacturers, which in turn depend on the current and anticipated
market demand for integrated circuits and products using integrated circuits.
The semiconductor industry is cyclical in nature and historically experiences
periodic downturns. During the past two years the semiconductor industry has
experienced severe swings of product demand and volatility in product pricing.
In early fiscal 1999 and fiscal 1998, the semiconductor industry reduced or
delayed significantly purchases of semiconductor manufacturing equipment and
construction of new fabrication facilities because of an industry downturn.
However, beginning in late fiscal 1999, we saw indications of a recovery, which
is expected to extend through fiscal 2000. Fluctuating levels of investment by
the semiconductor manufacturers and pricing volatility will continue to affect
materially our aggregate bookings, revenues and operating results. Even during
periods of reduced revenues, we must continue to invest in research and
development and to maintain extensive ongoing worldwide customer service and
support capabilities to remain competitive, which may harm our financial
results.

        WE DEPEND ON NEW PRODUCTS AND PROCESSES FOR OUR SUCCESS. FOR THIS
        REASON, WE ARE SUBJECT TO RISKS ASSOCIATED WITH RAPID TECHNOLOGICAL
        CHANGE

        Rapid technological changes in semiconductor manufacturing processes
subject us to increased pressure to maintain technological parity with deep
submicron process technology. We believe that our



                                       21
   22

future success depends in part upon our ability to develop, manufacture and
introduce successfully new products and product lines with improved
capabilities, and to continue to enhance our existing products. Due to the risks
inherent in transitioning to new products, we must forecast accurately demand
for new products while managing the transition from older products. If new
products have reliability or quality problems, reduced orders, higher
manufacturing costs, delays in acceptance of and payment for new products and
additional service and warranty expenses may result. In the past, product
introductions caused some delays and reliability and quality problems. We may be
unable to develop and manufacture new products successfully, or new products
that we introduce may fail in the marketplace, which would materially and
adversely affect our results from operations.

        We expect to continue to make significant investments in research and
development and to pursue joint development relationships with customers or
other members of the industry. We must manage product transitions or joint
development relationships successfully, as introduction of new products could
adversely affect our sales of existing products. Future technologies, processes
or product developments may render our current product offerings obsolete, or we
may be unable in a timely manner to develop and introduce new products or
enhancements to our existing products which satisfy customer needs or achieve
market acceptance. Furthermore, if we are unsuccessful in the marketing and
selling of advanced processes or equipment to customers with whom we have
strategic alliances, we may be unsuccessful in selling existing products to
those customers. In addition, in connection with our developing new products, we
will invest in significant levels of initial production inventory, and our
failure in a timely manner to complete commercialization of these new products
could result in inventory obsolescence, which would adversely affect our
financial results.

        WE ARE SUBJECT TO RISKS ASSOCIATED WITH THE INTRODUCTION OF A NEW
        PRODUCT

        During the second quarter of fiscal 1999, we began shipping units of our
Teres(TM) chemical mechanical planarization system, for which we recorded
revenue during the two quarters of fiscal 2000. We expect to face significant
competition from multiple current and future competitors. Among the companies
currently offering polishing systems are Applied Materials, Inc., Ebara
Corporation and SpeedFam-IPEC, Inc. We believe that other companies are
developing polishing systems and are planning to introduce new products to this
market, which may affect our ability to sell this new product.

        During the first quarter of fiscal 2000, we began shipping units of our
Exelan(TM) oxide etch system. We expect to face significant competition from
multiple current competitors. Among the companies currently offering oxide etch
systems are Applied Materials, Inc., and Tokyo Electron Limited.

        WE ARE SUBJECT TO RISKS RELATING TO PRODUCT CONCENTRATION AND LACK OF
        PRODUCT REVENUE DIVERSIFICATION

       We derive a substantial percentage of our revenues to date from a limited
number of products, and we expect these products to continue



                                       22
   23

to account for a large percentage of our revenues in the near term. Continued
market acceptance of our primary products is, therefore, critical to our future
success. Our business, operating results, financial condition and cash flows
could therefore be adversely affected by:

    -   a decline in demand for our products;

    -   a failure to achieve continued market acceptance of our products;

    -   an improved version of one of our products being produced by a
        competitor;

    -   technological change which we are unable to match in our products; and

    -   a failure to release new enhanced versions of our products on a timely
        basis.

        WE ARE DEPENDENT UPON A LIMITED NUMBER OF KEY SUPPLIERS

        We obtain certain components and sub-assemblies included in our products
from a single supplier or a limited group of suppliers. Each of our key
suppliers has a one year blanket purchase contract under which we may issue
purchase orders. We may renew these contracts periodically. Each of these
suppliers sold us products during at least the last four years, and we expect
that we will continue to renew these contracts in the future or that we will
otherwise replace them with competent alternative source suppliers. We believe
that we could obtain alternative sources to supply these products. Nevertheless,
a prolonged inability to obtain certain components could adversely affect our
operating results and result in damage to our customer relationships.

        ONCE A SEMICONDUCTOR MANUFACTURER COMMITS TO PURCHASE A COMPETITOR'S
        SEMICONDUCTOR MANUFACTURING EQUIPMENT IT TYPICALLY CONTINUES TO PURCHASE
        THAT EQUIPMENT, MAKING IT MORE DIFFICULT FOR LAM TO SELL ITS EQUIPMENT
        TO THAT CUSTOMER

        The semiconductor equipment industry is highly competitive. We expect to
continue to face substantial competition throughout the world. Semiconductor
manufacturers must make a substantial investment to install and integrate
capital equipment into a semiconductor production line. We believe that once a
semiconductor manufacturer selects a particular supplier's capital equipment,
the manufacturer generally relies upon that equipment for that specific
production line application. Accordingly, we expect it to be more difficult to
sell to a given customer if that customer initially selects a competitor's
equipment. We believe that to remain competitive we will require significant
financial resources to offer a broad range of products, to maintain customer
service and support centers worldwide and to invest in product and process
research and development.

        WE MAY LACK THE FINANCIAL RESOURCES OR TECHNOLOGICAL CAPABILITIES OF
        CERTAIN OF OUR COMPETITORS NEEDED TO CAPTURE INCREASED MARKET SHARE

        Large semiconductor equipment manufacturers who have the resources to
support customers on a worldwide basis are increasingly dominating the
semiconductor equipment industry. Certain of our competitors have substantially
greater financial resources and more



                                       23
   24

extensive engineering, manufacturing, marketing and customer service and support
resources than we do. In addition, there are smaller emerging semiconductor
equipment companies that may provide innovative technology which may have
performance advantages over systems we currently, or expect to, offer.

        We expect our competitors to continue to improve the design and
performance of their current products and processes and to introduce new
products and processes with enhanced performance characteristics. If our
competitors enter into strategic relationships with leading semiconductor
manufacturers covering products similar to those we sell or may develop, it
could adversely affect our ability to sell products to those manufacturers. For
these reasons, we may fail to continue to compete successfully worldwide.

        Our present or future competitors may be able to develop products
comparable or superior to those we offer or that adapt more quickly to new
technologies or evolving customer requirements. In particular, while we
currently are developing additional product enhancements that we believe will
address customer requirements, we may fail in a timely manner to complete the
development or introduction of these additional product enhancements
successfully, or these product enhancements may not achieve market acceptance or
be competitive. Accordingly, we may be unable to continue to compete effectively
in our markets, competition may intensify or future competition may have a
material adverse effect on our revenues, operating results, financial condition
and cash flows.

        OUR FUTURE SUCCESS DEPENDS ON INTERNATIONAL SALES

        International sales accounted for approximately 54% of our total revenue
in fiscal 1999, 55% in fiscal 1998, 57% in fiscal 1997, 66% for the six months
ended December 26, 1999 of fiscal 2000 and 46% for the six months ended December
31, 1998 of fiscal 1999. We expect that international sales will continue to
account for a significant portion of our total revenue in future years.
International sales are subject to risks, including:

    -   foreign exchange risks; and

    -   economic, banking and currency problems in the relevant region.

        We currently enter into foreign currency forward contracts to minimize
the short term impact of exchange rate fluctuations on yen-denominated assets,
and will continue to enter into hedging transactions in the future.

        A FAILURE TO COMPLY WITH ENVIRONMENTAL REGULATIONS MAY ADVERSELY AFFECT
        OUR OPERATING RESULTS

        We are subject to a variety of governmental regulations related to the
discharge or disposal of toxic, volatile or otherwise hazardous chemicals used
in the manufacturing process. We believe that we are in general compliance with
these regulations and that we have obtained (or will obtain or are otherwise
addressing) all necessary environmental permits to conduct our business, which
permits generally relate to the disposal of hazardous wastes. Nevertheless, the
failure to comply with present or future regulations could result in fines being
imposed on us, suspension of production, cessation of our



                                       24
   25

operations generally or reduction in our customers' acceptance of our products.
These regulations could require us to alter our current operations, to acquire
significant equipment or to incur substantial other expenses to comply with
environmental regulations. Our failure to control the use, sale or transport, or
adequately to restrict our discharge or disposal, of hazardous substances could
subject us to future liabilities.

        OUR ABILITY TO MANAGE POTENTIAL GROWTH; INTEGRATION OF POTENTIAL
        ACQUISITIONS AND POTENTIAL DISPOSITION OF PRODUCT LINES AND TECHNOLOGIES
        CREATES RISKS FOR US

        Our management may face significant challenges in improving financial
and business controls, management processes, information systems and procedures
on a timely basis, and expanding, training and managing our work force if we
experience additional growth. There can be no assurance that we will be able to
perform such actions successfully. In the future, we may make additional
acquisitions of complementary companies, products or technologies, or we may
reduce or dispose of certain product lines or technologies which no longer
complement our long-term strategy, such as our exiting of Flat Panel Display and
Chemical Vapor Deposition operations. Managing an acquired business or disposing
of product technologies entails numerous operational and financial risks,
including difficulties in assimilating acquired operations and new personnel or
separating existing business or product groups, diversion of management's
attention to other business concerns, amortization of acquired intangible assets
and potential loss of key employees or customers of acquired or disposed
operations. Our success will depend, to a significant extent, on the ability of
our executive officers and other members of our senior management to identify
and respond to these challenges effectively. There can be no assurance that we
will be able to achieve and manage effectively any such growth, integration of
potential acquisitions or disposition of product lines or technologies, or that
our management, personnel or systems will be adequate to support continued
operations. Any such inabilities or inadequacies would have a material adverse
effect on our business, operating results, financial condition and cash flows.

        An important element of our management strategy is to review acquisition
prospects that would complement our existing products, augment our market
coverage and distribution ability, or enhance our technological capabilities. We
may acquire additional businesses, products or technologies in the future. Any
acquisitions could result in changes such as potentially dilutive issuances of
equity securities, the incurrence of debt and contingent liabilities and the
amortization expense related to goodwill and other intangible assets, any of
which could materially adversely affect our business, financial condition and
results of operations and/or the price of our Common Stock.

        THE MARKET FOR OUR COMMON STOCK IS VOLATILE, WHICH MAY AFFECT OUR
        ABILITY TO RAISE CAPITAL OR MAKE ACQUISITIONS

        The market price for our common stock is volatile and has fluctuated
significantly over the past years. The trading price of our common stock could
continue to be highly volatile and fluctuate widely in response to factors,
including the following:



                                       25
   26

    -   general market or semiconductor industry conditions;

    -   variations in our quarterly operating results;

    -   shortfalls in our revenues or earnings from levels securities analysts
        expect;

    -   announcements of restructurings, technological innovations, reductions
        in force, departure of key employees, consolidations of operations or
        introduction of new products;

    -   government regulations;

    -   developments in or claims relating to patent or other proprietary
        rights;

    -   disruptions with key customers; or

    -   political, economic or environmental events occurring globally or in our
        key sales regions.

        In addition, the stock market has in recent years experienced
significant price and volume fluctuations. Recent fluctuations affecting our
common stock were tied in part to the actual or anticipated fluctuations in
interest rates, and the price of and market for semiconductors generally. These
broad market and industry factors may adversely affect the market price of our
common stock, regardless of our actual operating performance. In the past,
following volatile periods in the market price of stock, many companies become
the object of securities class action litigation. If we are sued in a securities
class action, we could incur substantial costs and it could divert management's
attention and resources and have an effect on the market price for our common
stock.

        RISK ASSOCIATED WITH OUR CALL AND PUT OPTIONS

        We have entered into a third party option transactions for the purchase
and sale of our stock. The option position will be of value to us if our stock
price exceeds the exercise price of the call options at the time the option is
exercised. Of course, our stock price could also decline. If our stock price on
the exercise date of the options were below the put option exercise price, we
would have to settle the put obligation by paying cash or the equivalent value
of our common stock obligation.

        During fiscal 1999, we entered into a third party option transactions
for the purchase and sale of our common stock, in order to offset the
antidilutive effect of a potential conversion into common stock of the $310.0
million Convertible Subordinated Notes (the "Notes") we previously issued and
which are due September 2, 2002. We have as of December 26, 1999 acquired call
options to purchase 1.24 million shares of our common stock: the weighted
average exercise price of these options is $33.87. The call options provide that
our maximum benefit at expiration is $53.90 per option share (the difference
between $87.77, which is the conversion price of the Notes, and the weighted
average exercise price of the call options). We have also entered into put
options with the same third parties covering 1.86 million shares of our common
stock, giving those third parties the right to sell to us shares of our common
stock at a weighted average price of $28.43 per share.

        THE POTENTIAL ANTI-TAKEOVER EFFECTS OF OUR BYLAWS PROVISIONS AND THE
        RIGHTS PLAN WE HAVE IN PLACE MAY AFFECT OUR STOCK PRICE AND INHIBIT A
        CHANGE OF CONTROL DESIRED BY SOME OF OUR STOCKHOLDERS



                                       26
   27

        On January 23, 1997, Lam adopted a Rights Plan (the "Rights Plan") in
which rights were distributed as a dividend at the rate of one right for each
share of our Common Stock, held by stockholders of record as of the close of
business on January 31, 1997, and thereafter. In connection with the adoption of
the Rights Plan, our Board of Directors also adopted a number of amendments to
our Bylaws, including amendments requiring advance notice of stockholder
nominations of directors and stockholder proposals.

        The Rights Plan may have certain anti-takeover effects. The Rights Plan
will cause substantial dilution to a person or group that attempts to acquire
Lam in certain circumstances. Accordingly, the existence of the Rights Plan and
the issuance of the related rights may deter certain acquirers from making
takeover proposals or tender offers. The Rights Plan, however, is not intended
to prevent a takeover. Rather it is designed to enhance the ability of our Board
of Directors to negotiate with a potential acquirer on behalf of all of our
stockholders.

        In addition, our Certificate of Incorporation authorizes issuance of
5,000,000 shares of undesignated preferred stock. Our Board of Directors,
without further stockholder approval, may issue this preferred stock on such
terms as the Board of Directors may determine, which also could have the effect
of delaying or preventing a change in control of Lam. The issuance of preferred
stock could also adversely affect the voting power of the holders of our common
stock, including causing the loss of voting control. Our Bylaws and indemnity
agreements with certain officers, directors and key employees provide that we
will indemnify officers and directors against losses that they may incur in
legal proceedings resulting from their service to Lam. Moreover, Section 203 of
the Delaware General Corporation Law restricts certain business combinations
with "interested stockholders", as defined by that statute.

        INTELLECTUAL PROPERTY AND OTHER CLAIMS AGAINST US CAN BE COSTLY AND
        COULD RESULT IN THE LOSS OF SIGNIFICANT RIGHTS WHICH ARE NECESSARY TO
        OUR CONTINUED BUSINESS AND PROFITABILITY

        Other parties may assert infringement, unfair competition or other
claims against us. Additionally, from time to time, other parties send us
notices alleging that our products infringe their patent or other intellectual
property rights. In such cases, it is our policy either to defend the claims or
to negotiate licenses on commercially reasonable terms. However, we may be
unable in the future to negotiate necessary licenses on commercially reasonable
terms, or at all, and any litigation resulting from these claims by other
parties may materially adversely affect our business and financial results.

        In October 1993, Varian Associates, Inc. ("Varian") sued us in the
United States District Court for the Northern District of California, seeking
monetary damages and injunctive relief based on our alleged infringement of
certain patents Varian held. We asserted defenses that the subject patents are
invalid and unenforceable, and that our products do not infringe these patents.
Litigation is inherently uncertain and we may fail to prevail in this
litigation. However, we believe that the Varian lawsuit will not materially



                                       27
   28

adversely affect our operating results or financial position. See Part II Item 1
of this Form 10-Q for a discussion of the Varian lawsuit.

        Additionally, in September 1999, Tegal Corporation ("Tegal") sued us in
the United States District Court for the Eastern District of Virginia, seeking
monetary damages and injunctive relief based on our alleged infringement of
certain patents Tegal holds. Specifically, Tegal identified our 4520XLe(TM) and
Exelan(TM) products as infringing the patents Tegal is asserting. Litigation is
inherently uncertain and we may fail to prevail in this litigation. However, we
believe that the Tegal lawsuit will not materially adversely affect our
operating results or financial position. See Part II Item 1 of this Form 10-Q
for a discussion of the Tegal lawsuit.

        WE MAY FAIL TO PROTECT OUR PROPRIETARY TECHNOLOGY RIGHTS, WHICH WOULD
        AFFECT OUR BUSINESS

        Our success depends in part on our proprietary technology. While we
attempt to protect our proprietary technology through patents, copyrights and
trade secret protection, we believe that our success depends on increasing our
technological expertise, continuing our development of new systems, increasing
market penetration and growth of our installed base, and providing comprehensive
support and service to our customers. However, we may be unable to protect our
technology in all instances, or our competitors may develop similar or more
competitive technology independently. We currently hold a number of United
States and foreign patents and pending patent applications. However, other
parties may challenge or attempt to invalidate or circumvent any patents United
States or foreign governments issue to us or these governments may fail to issue
pending applications. In addition, the rights granted or anticipated under any
of these patents or pending patent applications may be narrower than we expect
or in fact provide no competitive advantages.

ITEM 3. Quantitative And Qualitative Disclosures about Market Risk

        For financial market risks related to changes in interest rates and
foreign currency exchange rates, refer to Part II, Item 7A, Quantitative and
Qualitative Disclosures About Market Risk, in the Company's Annual Report on
Form 10-K for the year ended June 30, 1999.

        During fiscal 1999, we entered into a third party option transactions
for the purchase and sale of our common stock, in order to offset the
antidilutive effect of a potential conversion into common stock of the $310.0
million Convertible Subordinated Notes (the "Notes") we previously issued and
which are due September 2, 2002. We have as of December 26, 1999 acquired call
options to purchase 1.24 million shares of our common stock: the weighted
average exercise price of these options is $33.87. The call options provide that
our maximum benefit at expiration is $53.90 per option share (the difference
between $87.77, which is the conversion price of the Notes, and the weighted
average exercise price of the call options). We have also entered into put
options with the same third parties covering 1.86 million shares of our common
stock, giving those third parties the right to sell to us shares of our common
stock at a weighted average price of $28.43 per share.

        Below is a table showing, at assumed exercise prices for the put and
call options and market prices for our common stock, our gain or (loss) under
the put and call options upon exercise or upon maturity of the option
transactions.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

        In October 1993, Varian brought suit against the Company in the United
States District Court, for the Northern District of California, seeking monetary
damages and injunctive relief based on the Company's alleged infringement of
certain patents held by Varian. By order of the Court, those proceedings were
bifurcated into an initial phase to determine the validity of the Varian patents
and Lam's infringement (if any), and a secondary phase to determine damages to
Varian (if any) and whether Lam's infringement (if shown) was willful. On April
13, 1999, the Court issued an interlocutory order construing the meaning of the
terms of the patent claims at issue in the action. To date, however, there has
been no determination as to the actual scope of those claims, or whether Lam's
products have infringed or are infringing Varian's patents. The trial date
previously scheduled for March 2000 has been vacated, pending the courts
decision of certain motions. There have been no findings in the action which
have caused the Company reasonably to believe that any infringement, if found,
or any damages, if awarded, would have a material adverse effect on the
Company's operating results or the Company's financial position.

        In September 1999, Tegal brought suit against the Company in the United
States District Court, for the Eastern District of Virginia, seeking monetary
damages and injunctive relief based on the Company's alleged infringement of
certain patents held by Tegal. Specifically, Tegal identified the Company's
4520XLE and Exelan products as infringing the patents Tegal is asserting. On
Lam's motion, this case was transferred to California and is now pending in the
United States District Court for the Northern District of California. To date,
however, there has been no determination as to the actual scope of those claims,
or whether Lam's products have infringed or are infringing Tegal's patents. No
trial date is currently scheduled in the action. Furthermore, there have been no
findings in the action which have caused the Company reasonably to believe that
any infringement, if found, or any damages, if awarded, could have a material
adverse effect on the Company's operating results or the Company's financial
position.

        From time to time, Lam has received notices from third parties alleging
infringement of such parties' patent or other intellectual property rights by
the Company's products. In such cases, it is the policy of the Company to defend
the claims or negotiate licenses on commercially reasonable terms, where
considered appropriate. However, no assurance can be given that Lam will be able
in the future to negotiate necessary licenses on commercially reasonable terms,
or at all, or that any litigation resulting from such claims would not have a
material adverse effect on the Company's business and financial results.
