PART I

ITEM 1. BUSINESS

Mattson Technology, Inc. is a leading supplier of semiconductor wafer
processing equipment used in "front-end" fabrication of integrated circuits,
with an installed base of more than 2,400 tools in over 400 fabrication
facilities around the world. We are among the market leaders in worldwide sales
of dry strip equipment, rapid thermal processing ("RTP") equipment, wet surface
preparation equipment, and plasma-enhanced chemical vapor deposition ("PECVD")
equipment. Our integrated circuit manufacturing equipment utilizes innovative
technology to deliver advanced processing capability and high productivity. We
provide our customers with worldwide support through our international technical
support organization and our comprehensive warranty program.

We are a leading provider of equipment that enables our customers to
transition from 200 mm to 300 mm silicon wafers and to produce integrated
circuits with feature geometries below 0.18 microns. We were among the earliest
entrants into the market for 300 mm tools, and we offer 300 mm compatible
products for dry strip, RTP, wet surface preparation and PECVD. To date, we have
sold over two hundred 300 mm compatible systems. Our patented inductively
coupled plasma technology for our dry strip systems, dual-sided heating
technology for our RTP systems, and drying technology for our wet products
provide innovative solutions for the production of features below 0.18 micron.
In December 2001, we introduced the Aspen Highlands III, which removes low-K
resist and residue from dual damascene copper layers with features as small as
0.10 microns.

2


During 2001, we instituted several actions designed to meet the challenging
conditions posed by the industry downturn. At the beginning of 2001, we acquired
the semiconductor equipment division of STEAG Electronic Systems AG, and CFM
Technologies, Inc. These acquisitions were intended to create a combined company
with stronger market positions in multiple products used in front-end integrated
circuit fabrication, greater importance as a vendor to key customers, greater
technical capabilities and intellectual property assets, and broader worldwide
presence and customer support. During 2001, we made significant organizational
changes to integrate the acquisitions while focusing our product offerings,
reducing our overhead and sizing our business for current market conditions. We
also made significant changes to our management team and added several senior
executives with considerable technical, managerial and sales experience in the
semiconductor equipment industry.

We are incorporated in Delaware. Our principal executive offices are
located at 2800 Bayview Drive, Fremont, CA 94538, and our contact telephone
number is (510) 492-6112 and our general telephone number is (510) 657-5900. Our

Industry Background

Manufacturing an integrated circuit, commonly called a chip, requires a
number of complex steps and processes. Most integrated circuits are built on a
base of silicon, called a wafer, and consist of two main structures. The lower
structure is made up of components, typically transistors or capacitors, and the
upper structure consists of the circuitry that connects the components.
Front-end processing is broadly divided into "front-end of line" and "back-end
of line" processing. Fabrication at the "front-end of line" includes the steps
needed to build transistors, up to the first layer of metalization. The
subsequent steps, which create the interconnect metal layers, are called the
"back-end of line." Building an integrated circuit requires the deposition of a
series of film layers, which may be conductors, dielectrics (insulators) or
semiconductors. The deposition of these film layers is interspersed with
numerous other processing steps that create circuit patterns, remove portions of
the film layers and perform other functions such as heat treatment, measurement
and inspection. Each step of the manufacturing process for integrated circuits
requires specialized manufacturing equipment. Although the semiconductor
industry is cyclical, and currently experiencing a period of downturn and
decreased demand, historically, the overall growth of the semiconductor industry
and the increasing complexity of integrated circuits has led to increasing
demand for advanced semiconductor capital equipment.

Semiconductor Manufacturing Industry Matures

In periods of economic growth, the semiconductor market has grown, fueled in
large part by the growth of the personal computer markets and the emergence of
markets such as wireless communication and digital consumer electronics. In past
years it was sufficient for semiconductor equipment companies to be either the
first on the market or have the most advanced technology to succeed, however, in
order to meet the increasing demand in the last upward cycle, sheer size became
increasingly important to achieve customer confidence and sales opportunities.
This has contributed to recent consolidations in the semiconductor industry and
in the companies that supply them capital equipment. Larger sized equipment
providers can deliver customers a variety of solutions for their factory without
forcing them to coordinate and deal with a large number of suppliers. Larger
equipment companies can also provide a more comprehensive worldwide
infrastructure to service and support the broad line of products with an
increased staff, product spares and strategically located warehouses that a
smaller company cannot supply, and can more effectively respond to industry
downturns such as has been experienced in the current cycle.

Previous growth in the semiconductor industry has also been fueled by the
need to supply increasingly complex, higher performance integrated circuits,
while continuing to reduce cost, a factor that remains important during the
downturn. The more complex integrated circuits and the accompanying reductions
in feature size require more advanced and expensive wafer fabrication equipment,
which increases the average cost of advanced wafer fabrication facilities. For
example, the average cost in 1984 for a 64 kilobit dynamic random access memory
integrated circuit, called a DRAM, fabrication facility was approximately $60.0
million. Today the cost for a 256 megabit DRAM fabrication facility can range
from $1.7 billion to $2.5 billion. As the semiconductor industry matures and
pricing becomes more competitive as a result of both the maturing market and the
industry downturn, it is becoming increasingly apparent that the larger
semiconductor manufacturers are increasingly restricting the number of suppliers
that they deal with, while making stronger demands that their suppliers provide
more products with higher productivity.

3


Semiconductor manufacturers have focused on several areas to improve their
productivity over the years, including:

* reducing feature size of integrated circuits;

* increasing manufacturing yields;

* improving the utilization of wafer fabrication equipment; and

* increasing the wafer size.

The industry is now reaching the practical limits of some of these
techniques, so that it is becoming increasingly difficult to obtain further
productivity gains in this way.

Reducing feature sizes. Smaller feature sizes allow more circuits to fit on
one wafer. Due to this reduction in feature size, the semiconductor industry has
historically been able to double the number of transistors on a given space of
silicon every 18 to 24 months. These reductions have contributed significantly
to reducing the manufacturing cost per chip. Continued innovation in equipment
technology would be required, however, to maintain this trend in device size
reduction.

Higher manufacturing yields. In the last fifteen years, manufacturing yields,
or the percentage of good integrated circuits per wafer, have increased
substantially, while the time to reach maximum yield levels during a production
lifecycle has decreased significantly. For example, the percentage of good DRAMs
per wafer during initial production has increased from 20% fifteen years ago to
over 80% at present. Given this high yield, the potential for further yield
improvement per wafer is limited.

Improved equipment utilization. The utilization of semiconductor
manufacturing lines has improved in the last ten years. During periods of full
capacity manufacturing lines operate continuously, with equipment run at
utilization rates of greater than 90%, leaving limited room for further
improvement in equipment utilization.

Larger wafer sizes. By increasing the wafer size, integrated circuit
manufacturers can produce more circuits per wafer, thus reducing the overall
manufacturing costs per chip. Leading edge wafer fabrication lines are currently
using 300 millimeter diameter wafers, up from the 200 millimeter diameter wafers
used only two years ago. We believe that many more manufacturers will add 300
millimeter production capabilities within the next two to five years. Although
the transition to a 300 millimeter wafer size will reduce overall manufacturing
costs per chip, we do not believe that the semiconductor industry will
transition as quickly to sizes larger than 300 millimeter in the future,
limiting the further impact on overall manufacturing costs per chip.

Equipment Productivity Has Declined

While the semiconductor manufacturing industry has achieved significant
productivity gains through technological advances during the last ten to fifteen
years, equipment productivity has actually declined in favor of improved process
control. Demands from integrated circuit manufacturers for better process
quality control, reduced feature sizes and larger wafer sizes have resulted in a
shift from batch processing, where multiple wafers are processed simultaneously,
to single wafer processing, where one wafer is processed at a time. Although
this shift has enhanced semiconductor quality, it has reduced total wafer
throughput and increased overall equipment cost.

Faced with diminishing productivity gains and increasing equipment costs,
integrated circuit manufacturers have challenged equipment manufacturers to
provide more cost-effective, higher productivity fabrication equipment. This
challenge has led to the use of cost of ownership to measure productivity. Cost
of ownership measures the costs associated with the operation of equipment in a
fabrication line. We calculate the cost of ownership by first estimating the
total costs to operate a system including depreciation, overhead and labor and
materials, and then dividing those costs by the total wafer production by the
system.

The Mattson Solution

We provide our customers with multiple product lines that deliver advanced
processing capability for front-end integrated circuit fabrication. We are among
the market leaders in each of our target front-end of line markets, and offer
equipment to perform a broad range of semiconductor manufacturing steps in dry
strip, RTP, wet surface preparation and plasma-enhanced CVD, as well as offering
products for back-end of line processing. We continue to invest in research and
development with the goal of expanding our product offerings and increasing our
market share within our target markets.

The Mattson Strategy

Our strategy for success focuses on five key areas:

Maintain and Build Leadership Across the Front-end of Line. We are a world
leader in the dry strip market, and we believe we are the second largest
supplier of RTP products in the world, among the top six providers of wet
surface preparation products, and among the top six providers of PECVD products,
representing a broad product portfolio for front-end of line fabrication
processes. As a result, we are positioned to address a broader range of our
customers' problems with our unique process technology and value-added
solutions. We believe our increased market presence will help us to gain market
share for our established products as we continue to focus on front-end of line
processing technologies, while gaining market exposure for our new product
lines.

Leverage Innovative Technologies and Provide Product Differentiation. We
intend to continue applying our technology leadership and design expertise to
provide new solutions that combine advanced technology with higher productivity.
In December 2001, we introduced the Aspen III Highlands, an advanced 200/300 mm
system designed for low-k cleaning and high-dose implant resist removal. Our
patented technologies include inductively coupled plasma technology for dry
strip, dual-sided lamp technology for RTP, and Marangoni drying technology for
wet surface preparation products. These technologies offer process control
advantages that take on increasing importance for the manufacture of smaller
device structures. We plan to leverage our technology and development
capabilities to bring to market innovative solutions that address specific,
front-end of line processing needs in the semiconductor manufacturing industry.

Pursue Leadership in the 300 Millimeter Market. We plan to expand our
leadership and increase our market share in the 300 mm market. Our 300 mm
compatible tools include Aspen III systems (Strip, LiteEtch, PECVD and our
newest Highlands product), our 3000 RTP products, and our AWP300 and OMNI300 wet
surface preparation products. We have sold more than two hundred 300 mm
compatible systems, and our systems are production qualified at leading customer
sites. We are also working with industry consortia as well as our customers to
ensure that our tools meet future 300 mm automation requirements.

Provide World Class, Global Customer Support. Our international customer
support organization is a critical element in establishing and maintaining
long-term relationships with our customers. We have reached a size that allows
us to meet the service requirements of large customers on a global basis,
including foundry customers in South East Asia. We are expanding our service
capability to address the emerging foundry market in China. We strive to attain
preferred vendor status and build customer loyalty by delivering highly reliable
products, customer service and support. In 2001, we received VLSI's 10 BEST
award for Suppliers of Wafer Processing Equipment for customer satisfaction. We
intend to continue to strengthen our commitment to provide continuous service,
support and global infrastructure.

Implement Operational Excellence to Manage Industry Cycles. We continuously
work to improve the quality of the products and services we deliver to our
customers, and to improve our operations, information systems and financial
performance. In 2001, we implemented an organizational restructuring to align
our organizational requirements and our sales, support and product development
organizations with the needs of our customers across our multiple product lines
and to size our infrastructure with the current business environment. The
restructuring has led to a significant reduction in our cost structure and
corporate overhead. We believe we are now appropriately sized for expected
business conditions this year, with the flexibility to respond if demand in our
industry increases. We intend to focus on improving our organization and our
information systems, and on reducing corporate and manufacturing overhead, to
help manage our operations through industry cycles. Our manufacturing facility
in the United States and one of our facilities in Germany are ISO 9001
certified, with certification of our other facility in process. We intend to
continue investing in our product and technology development, in our customer
support infrastructure, and in our information and manufacturing systems, to
improve our operational performance in the future.

Markets, Applications and Products

Dry Strip Market

A strip system removes photoresist and residues from a wafer following each
step of film deposition or diffusion processing in preparation for the next
processing step. Methods for stripping photoresist include wet chemistries and
dry or plasma technologies. Wet chemical stripping removes photoresist by
immersing the wafer into acid or solvent baths. Dry stripping systems, such as
our Aspen Strip, create gaseous atomic oxygen to which the wafer is exposed to
remove the unwanted residues.


5


The demand for photoresist strip equipment has grown as the complexity and
number of strip steps required for each wafer have increased. Complex integrated
circuits require multiple additional photoresist stripping steps, which increase
cost and cycle time, create environmental concerns, increase cleanroom space
requirements and reduce yield. The increase in strip steps in the integrated
circuit manufacturing process has led to a need for semiconductor manufacturers
to increase their photoresist strip capacity and to place greater emphasis on
low damage results and residue-free photoresist stripping. The added complexity
of the strip process has also contributed to higher average selling prices of
the equipment.

Fabrication of integrated circuits with feature sizes under 0.18 micron
requires advanced dry strip technologies such as our Aspen Strip. In addition,
faster integrated circuit devices require new interconnect materials, such as
low capacitance, or low-k dielectric films and copper for conducting materials.
The use of these new materials creates new challenges for photoresist stripping
equipment. The resist or residues must be removed from these materials without
degrading the low-k materials and without oxidizing any exposed copper.

Our dry strip products encompass both 200 and 300 mm products on our high
productivity "Aspen" platform, using our patented, inductively coupled plasma
technology. We have an installed base of approximately 1,000 dry strip systems
currently installed in production facilities around the world. We continue to be
an industry leader in dry strip technology, and in December 2001 we introduced
an advanced low-K resist and residue removal system called the Aspen III
Highlands. At several Beta sites, our Highlands product has already proven its
ability to preserve low-K material integrity and simplify integration schemes by
reducing operational steps.


Rapid Thermal Processing

In rapid thermal processing ("RTP"), semiconductor wafers are rapidly heated
to process temperature, held for a few seconds, and rapidly cooled. This thermal
process is critical to achieve the exact electrical parameters necessary for the
integrated circuit to operate. Historically, diffusion furnaces have been used
to heat-treat large batches of wafers. However, diffusion furnaces have long
processing times, which is unacceptable for many leading-edge device fabrication
processes. In addition, as device features have become smaller, the total
allowable temperature exposure of the wafer, or the thermal budget, has
decreased. RTP subjects the wafer to much shorter processing times, thus
reducing the thermal budget. Individual wafers are rapidly heated to process
temperature, held for a few seconds and rapidly cooled.

As the device geometries of integrated circuits continue to shrink and the
number of semiconductor wafers increases, the need has grown for RTP equipment
that can meet ever more stringent processing demands, while maintaining
uniformity and repeatability to ensure the integrity of the integrated circuit.

We are one of the industry leaders in RTP technology. Our products feature
patented, dual-sided, lamp-based technology that achieves good control, process
uniformity and repeatability. Our product line includes: the 2800 with over 500
units installed worldwide, the 2800cs for compound semiconductor processing, the
2900 for 200 mm applications, and the 3000 series for 300 mm fabrication and
advanced steam applications. We are extending this technology into oxidation
applications that use RTP to grow film layers. We have announced the sale of the
former AG Associates RTP portion of our product line to Metron Technology, NV.
In keeping with our focus on customer satisfaction and our commitment to provide
continuous service and support, we chose to transition the mature AG 4000 and
8000 series RTP products to a provider capable of embracing these products as a
primary focus. The transitioning of these mature products to Metron Technology
will allow us to focus on enhancing our leading-edge 2000 and 3000 series RTP
products while developing the next generation of innovative RTP tools.


Wet Surface Preparation

Wet chemical cleaning strips away photoresist and other residues by immersing
the wafer into acid or solvent baths and thoroughly cleaning the wafer surface.
This is critical in preparing the surface of the wafer for the building of
transistors. Wet processing steps have traditionally been accomplished using wet
benches and spray tools. Advanced wet benches utilize a succession of open
chemical baths and extensive robotic automation to move wafers from one chemical
or rinse bath to the next. Spray tools subject wafers to sequential spray
applications of chemicals as the wafers are spun inside an enclosed chamber.
There are a number of areas in the semiconductor manufacturing process where wet
surface preparation offers the most cost effective solution to cleaning and
etching the wafers.

6



"Critical cleans" are those wet surface preparation steps that are performed
in front-end processing to remove surface contamination prior to performing
highly sensitive fabrication steps such as gate oxidation or diffusion. To date,
most of our wet surface preparation systems have been purchased by semiconductor
manufacturers for use in these applications. Wet surface preparation is also
commonly used in the front-end to etch the surface of the wafer to remove
silicon dioxide or other surface material. It is generally important to tightly
control the amount of material removed and the uniformity of the etch. These
etching steps are often performed as part of a wet surface preparation sequence
rather than as stand-alone operations. Most of the wet surface preparation
systems we sell perform critical etching and cleaning applications.

Our advanced patented drying method provides clean wafers with almost no
watermarks or residue. This technology is used to fabricate advanced integrated
circuits with feature sizes below 0.18 microns, and we maintain valuable
intellectual property rights in this technology. Our "Marangoni" drying systems
are sold with complete wet processing systems, as stand-alone systems to
end-users and to competitors as original equipment manufacturer modules. We
offer two main wet chemical product lines: the OMNI and the AWP. Our wet surface
preparation products include traditional multi-bath wet benches, advanced
single-bath processing systems and combinations (so called "Hybrids") and drying
systems. We are currently focused on reducing the cost and enhancing the modular
designs of our existing products to improve profitability, while we continue to
develop next generation technologies for wet surface preparation.

Plasma Enhanced Chemical Vapor Deposition

Chemical vapor deposition processes are used to deposit insulating and
conducting films on wafers. These films are the basic material used to form the
resistors, capacitors, and transistors of an integrated circuit. These materials
are also used to form the wiring and insulation between these electrical
components.

As feature sizes continue to decrease, chemical vapor deposition processing
equipment must meet increasingly stringent requirements. Particles or defect
densities must be minimized and controlled to achieve the desired yields. Film
properties such as stress must also be improved and more tightly controlled.
Compatibility with metallization steps, such as aluminum and copper deposition,
is critical. Finally, as process complexity increases with the use of low-k and
dual damascene processing solutions, the number of plasma-enhanced chemical
vapor deposition steps increases significantly, and system productivity
increases in importance.

We are focused on PECVD applications at the front-end of the fabrication
line, and our products utilize platform and robotic technology based on our
leading Aspen dry strip products, that we believe gives us performance and
productivity advantages. We offer a PECVD process to deposit insulating films.
PECVD allows the system to process wafers at a relatively low temperature,
reducing the risk of device parameter drift during processing at the front-end
of line and of damage to metalization layers during processing at the back-end
of line. Our Aspen III PECVD product has been production-certified at leading
fabrication sites for both 200 mm and 300 mm applications. We are currently
focusing on developing additional PECVD applications that complement our other
front-end of line products.

Epi Market

Epitaxial, or Epi, deposition systems grow a layer of extremely pure silicon
on a wafer in a uniform crystalline structure to form a high quality base for
building certain types of chips. The silicon properties of the epitaxy produce a
more controlled silicon growth than do manufactured silicon wafers and offer
features that differentiate it from manufactured silicon wafers.

The Epi market is broken into two segments: applications that require thin
Epi, which are typically less than five microns thick, and applications that
require thicker Epi film layers, including analog and power devices, sometimes
as thick as 100 microns. Our EpiPro series uses a dual chamber batch system that
addresses the thick Epi market. Our EpiPro series was introduced in 1998.


7


Isotropic Etch Market

The etching process selectively removes patterned material from the surface
of a wafer to create the device structures. With the development of sub-micron
integrated circuit feature sizes, dry, or plasma, etching has become one of the
most frequently used processes in semiconductor manufacturing.

Our Aspen II and III LiteEtch systems use our patented ICP source technology
for critical etching operations on 200 and 300 mm wafers.

An isotropic, or multi-directional, etch system performs a variety of etch
processes on semiconductor wafers that can be used in several steps in a typical
0.18 micron chip fabrication.


Customer Support

Our customer support organization is critical to establishing and maintaining
the long term relationships with our customers. Our customer support
organization is headquartered in Fremont, California, with additional offices
located domestically throughout the U.S. and internationally in Germany, Italy,
Japan, Korea, Singapore, Taiwan and the United Kingdom, and are currently in the
process of establishing an office in China. Our support personnel have technical
backgrounds, with process, mechanical, and electronics training, and are
supported by our engineering, software and applications personnel. Support
personnel install systems, perform warranty and out-of-warranty service, and
provide sales support.

We offer competitive, comprehensive warranties on all our products and
provide access to training at our headquarters. We maintain spare parts depots
in most regions for four-hour parts turnaround and provide regional field and
process support.

In 2001, we received VLSI's 10 BEST award for Suppliers of Wafer Processing
Equipment, which CFM and the Semiconductor Division of STEAG, were awarded in
2000. The STEAG Semiconductor Division appeared in the 10 BEST rankings four
previous times under the names AST Elektronik and AG Associates.

Sales and Marketing

We sell our systems primarily through our direct sales force. In addition to
the direct sales force at our headquarters in Fremont, California, we have
domestic regional sales offices located throughout the United States, and
maintain sales support offices in France, Germany, Italy, Japan, Korea,
Singapore, Taiwan and the United Kingdom.

Prior to the merger, the STEAG Semiconductor Division utilized PRIMA as a
distributor for RTP and wet surface preparation systems in China. While we plan
to maintain our distribution relationship with Prima, we also plan to establish
a direct sales and support organization in China.

While maintaining our own direct sales force in Japan for most of our
products, we are continuing our relationship with Canon for the distribution of
our RTP systems in Japan.

International sales accounted for 78% of total net sales in 2001, 69% in 2000
and 71% in 1999. We anticipate that international sales will continue to account
for a significant portion of our net sales. International sales are subject to
certain risks, including unexpected changes in regulatory requirements, exchange
rates, tariffs and other barriers, political and economic instability,
difficulties in accounts receivable collections, extended payment terms,
difficulties in managing distributors or representatives, difficulties in
staffing and managing foreign subsidiary operations and potentially adverse tax
consequences. Because of our dependence upon international sales in general, and
on sales to Japan and Pacific Rim countries in particular, we are particularly
at risk to effects from developments such as the recent Asian economic problems.
Our foreign sales are also subject to certain governmental restrictions,
including the Export Administration Act and the regulations promulgated under
this Act. For a discussion of the risks associated with our international sales,
see "Risk Factors That May Affect Future Results and Market Price of Stock--We
Are Highly Dependant on Our International Sales, and Face Significant Economic
and Regulatory Risks Because a Majority of Our Net Sales Are From Outside the
United States."

Customers

Customers for our products include nearly all of the world's top 20
semiconductor manufactures and foundries. A representative list of our major
customers includes:

* Hewlett Packard * ProMOS Technologies * Tech Semiconductor
* Hynix * Samsung * Texas Instruments
* IBM Microelectronics * Silicon Integrated Systems * TSMC
* Infineon * SMIC * UMC Group
* NEC Corporation * Sony

In 2001, one customer, Infineon, accounted for more than 10% of our revenue.
Infineon and ProMos accounted for approximately 19% and 16%, respectively, of
our total bookings. Although the composition of the group comprising our largest
customers has varied from year to year, our top ten customers accounted for 58%
of our net sales in 2001, 59% in 2000, and 63% in 1999. For a discussion of
risks associated with changes in our customer base, see "Risk Factors That May
Affect Future Results and Market Price of Our Stock-- We Are Dependant on Large
Purchases From a Few Customers, and Any Loss, Cancellation, Reduction or Delay
in Purchases By, or Failure to Collect Receivables From, These Customers Could
Harm Our Business."

Backlog

We schedule production of our systems based on both backlog and regular sales
forecasts. We include in backlog only those systems for which we have accepted
purchase orders and assigned shipment dates within the next 12 months. Orders
are often subject to cancellation or delay by the customer with limited or no
penalty. Our backlog was approximately $60.0 million as of December 31, 2001,
$109.9 million as of December 31, 2000 and $56.1 million as of December 31,
1999. The backlog as of December 31, 2001 includes backlog from the STEAG
Semiconductor Division and CFM, which we acquired on January 1, 2001. The
year-to-year fluctuation is due primarily to the downturn in the semiconductor
industry and the continuing soft demand in the semiconductor equipment market.
Because of possible future changes in delivery schedules and cancellations of
orders, our backlog at any particular date is not necessarily representative of
actual sales to be expected for any succeeding period and our actual sales for
the year may not meet or exceed the backlog represented. During periods of
industry downturns, such as we experienced in 2001, we have experienced
significant cancellations and delays and push-out of orders that were previously
booked and included in backlog. As a result, because customers did not
reschedule delivery dates, backlog declined in the fourth quarter of 2001 due to
customer cancellations and push out of orders.

Research, Development and Engineering

Our research, development and engineering efforts are focused upon our
multi-product strategy. Continued and timely development of new products and
enhancements to existing products are necessary to maintain our competitive
position. Key activities during fiscal year 2001 involved bringing the 3000
Steam RTP system into manufacturing production and introducing the Aspen III
Highlands. Over the next year, we plan to focus our efforts on developing
products across our product lines, with an emphasis on 300 millimeter
applications.

We maintain applications laboratories in Fremont, California and in
Pliezhausen and Dornstadt, Germany to test new systems and customer-specific
equipment designs. By basing products on existing and accepted product lines in
the thermal, plasma and wet surface preparation markets, we believe that we can
focus our development activities on producing new products more quickly and at
relatively low cost.

The markets in which we compete are characterized by rapidly changing
technology, evolving industry standards and continuous improvements in products
and services. Because of continual changes in these markets, we believe that our
future success will depend upon our ability to continue to improve our existing
systems and process technologies and to develop systems and new technologies
that compete effectively. In addition, we must adapt our systems and processes
to technological changes and to support emerging industry standards for target
markets. We cannot be sure that we will complete our existing and future
development efforts within our anticipated schedule or that our new or enhanced
products will have the features to make them successful. We may experience
difficulties that could delay or prevent the successful development,
introduction or marketing of new or improved systems or process technologies.


9



In addition, these new and improved systems and process technologies may not
meet the requirements of the marketplace and achieve market acceptance.
Furthermore, despite testing by us, difficulties could be encountered with our
products after shipment, resulting in loss of revenue or delay in market
acceptance and sales, diversion of development resources, injury to our
reputation or increased service and warranty costs. The success of new system
introductions is dependent on a number of factors, including timely completion
of new system designs and market acceptance. If we are unable to improve our
existing systems and process technologies or to develop new technologies or
systems, we may lose sales and customers.

Our research, development and engineering expenses were $61.1 million for the
year ended December 31, 2001, $28.5 million for 2000 and $19.5 million for 1999,
representing 26.6% of net sales in 2001, 15.8% in 2000 and 18.9% in 1999. The
expenses for 2001 include research, development and engineering expenses that
reflect our acquisition of the STEAG Semiconductor Division and CFM.

Competition

The global semiconductor fabrication equipment industry is intensely
competitive and is characterized by rapid technological change and demanding
customer service requirements. Our ability to compete depends upon our ability
to continually improve our products, processes and services and our ability to
develop new products that meet constantly evolving customer requirements.

A substantial capital investment is required by semiconductor manufacturers
to install and integrate new fabrication equipment into a semiconductor
production line. As a result, once a semiconductor manufacturer has selected a
particular supplier's products, the manufacturer often relies for a significant
period of time upon that equipment for the specific production line application
and frequently will attempt to consolidate its other capital equipment
requirements with the same supplier. Accordingly, it is difficult for us to sell
to a particular customer for a significant period of time after that customer
has selected a competitor's product, and it may be difficult for us to unseat an
existing relationship that a potential customer has with one of our competitors
in order to increase sales of our products to that customer.

Each of our product lines competes in markets defined by the particular wafer
fabrication process it performs. In each of these markets we have multiple
competitors. At present, however, no single competitor competes with us in all
of the market segments in which we compete. Competitors in a given technology
tend to have different degrees of market presence in the various regional
geographic markets. Competition is based on many factors, primarily
technological innovation, productivity, total cost of ownership of the systems,
including yield, price, product performance and throughput capability, quality,
contamination control, reliability and customer support. We believe that our
competitive position in each of our markets is based on the ability of our
products and services to address customer requirements related to these
competitive factors.

Our principal competitors in the dry strip market include Axcellis and
Novellus. We believe that we compete favorably on each of the competitive
elements in this market and estimate that we are one of the top two providers of
dry strip products. The principal competitor for our RTP systems is Applied
Materials. Principal competitors for our wet surface preparation products
include Akrion, Dainippon Screen, FSI International, SCP Global Technologies,
Semitool, S.E.S., SEZ, Tokyo Electron and Verteq. The market in which our Aspen
LiteEtch products compete is a relatively small niche market with no dominant
competitors. Principal competitors for our Aspen LiteEtch systems include
Novellus, Lam Research, Shibaura Mechatronics and Tegal. Principal competitors
for our PECVD systems include Applied Materials, ASM International and Novellus
Systems, with Applied Materials and Novellus representing a major share of the
market. Principal competitors for our EpiPro systems include Kokusai
Semiconductor Equipment, LPE Products, Moore Technology and Toshiba.

We may not be able to maintain our competitive position against current and
potential competition. New products, pricing pressures, rapid changes in
technology and other competitive actions from both new and existing competitors
could materially affect our market position. Some of our competitors have
substantially greater installed customer bases and greater financial, marketing,
technical and other resources than we do and may be able to respond more quickly
to new or changing opportunities, technologies and customer requirements. Our
competitors may introduce or acquire competitive products that offer enhanced
technologies and improvements. In addition, some of our competitors or potential
competitors have greater name recognition and more extensive customer bases that
could be leveraged to gain market share to our detriment. We believe that the
semiconductor equipment industry will continue to be subject to increased
consolidation, which will increase the number of larger, more powerful companies
and increase competition.

10



Manufacturing

Our manufacturing operations are based in the U.S. and Europe and consist of
procurement, assembly, test, quality assurance and manufacturing engineering.
Our current dry strip, PECVD, RTP, wet surface preparation, epi and LiteEtch
systems are based on a variety of platforms. The products utilize common
subassemblies and components. Many of the major assemblies are procured complete
from outside sources. We focus our internal manufacturing efforts on those
precision mechanical and electro-mechanical assemblies that differentiate our
systems from those of our competitors. We have manufacturing capability for our
thermal (RTP, epi), films (PECVD, strip) and etch products in Fremont,
California and Dornstadt, Germany. Wet surface preparation products are
manufactured in Pliezhausen and Donaueschingen, Germany.

Some of our components are obtained from a sole supplier or a limited group
of suppliers. We generally acquire these components on a purchase order basis
and not under long term supply contracts. Our reliance on outside vendors
generally, and a limited group of suppliers in particular, involves several
risks, including a potential inability to obtain an adequate supply of required
components and reduced control over pricing and timely delivery of components.
Because the manufacture of certain of these components and subassemblies is an
extremely complex process and can require long lead times, we could experience
delays or shortages caused by suppliers. Historically, we have not experienced
any significant delays in manufacturing due to an inability to obtain
components, and we are not currently aware of any specific problems regarding
the availability of components that might significantly delay the manufacturing
of our systems in the future. However, any inability to obtain adequate
deliveries or any other circumstance that would require us to seek alternative
sources of supply or to manufacture such components internally could delay our
ability to ship our systems and could have a material adverse effect on us.

We are subject to a variety of federal, state and local laws, rules and
regulations relating to the use, storage, discharge and disposal of hazardous
chemicals used during our sales demonstrations and research and development.
Public attention has increasingly been focused on the environmental impact of
operations which use hazardous materials. Failure to comply with present or
future regulations could result in substantial liability to us, suspension or
cessation of our operations, restrictions on our ability to expand at our
present locations or requirements for the acquisition of significant equipment
or other significant expense. To date, compliance with environmental rules and
regulations has not had a material effect on our operations.

Intellectual Property

We rely on a combination of patent, copyright, trademark and trade secret
laws, non-disclosure agreements and other intellectual property protection
methods to protect our proprietary technology. We hold a number of United States
patents and corresponding foreign patents and have a number of patent
applications pending covering various aspects of our products and processes.
Where appropriate, we intend to file additional patent applications on
inventions resulting from our ongoing research, development and manufacturing
activities to strengthen our intellectual property rights.

Although we attempt to protect our intellectual property rights through
patents, copyrights, trade secrets and other measures, we cannot be sure that we
will be able to protect our technology adequately, and our competitors could
independently develop similar technology, duplicate our products or design
around our patents. To the extent we wish to assert our patent rights, we cannot
be sure that any claims of our patents will be sufficiently broad to protect our
technology or that our pending patent applications will be approved. In
addition, there can be no assurance that any patents issued to us will not be
challenged, invalidated or circumvented, that any rights granted under these
patents will provide adequate protection to us, or that we will have sufficient
resources to protect and enforce our rights. In addition, the laws of some
foreign countries may not protect our proprietary rights to as great an extent
as do the laws of the United States. As a result of the merger, we are involved
in several patent lawsuits that had been brought by or against CFM, which are
discussed furthur below under Item 3: Legal Proceedings.

As is customary in our industry, from time to time we receive or make
inquiries regarding possible infringement of patents or other intellectual
property rights. Although there are no pending claims against us regarding
infringement of any existing patents or other intellectual property rights or
any unresolved notices that we are infringing intellectual property rights of
others, such infringement claims could be asserted against us or our suppliers
by third parties in the future. Any claims, with or without merit, could be
time-consuming, result in costly litigation, result in loss or cancellation of
customer orders, cause product shipment delays, subject us to significant
liabilities to third parties, require us to enter into royalty or licensing
agreements, or prevent us from manufacturing and selling our products.


11


If our products were found to infringe a third party's proprietary rights, we
could be required to enter into royalty or licensing agreements in order to
continue to be able to sell our products. Royalty or licensing agreements, if
required, may not be available on terms acceptable to us or at all, which could
seriously harm our business. Our involvement in any patent dispute or other
intellectual property dispute or action to protect trade secrets and know-how
could have a material adverse effect on our business.

Employees

As of January 1, 2001, immediately following our acquisition of the STEAG
Semiconductor Division and CFM, we had approximately 2,000 employees. During
2001, we implemented reductions in force of 466 employees. As of December 31,
2001, we had 1,424 employees. There were 362 employees in manufacturing
operations, 338 in research, development and engineering, 556 in sales,
marketing, field service and customer support, and 168 in general,
administrative and finance.

During 2001, we significantly reduced our operations and our workforce.
However, the success of our future operations will depend in large part on our
ability to recruit and retain qualified employees, particularly those highly
skilled design, process and test engineers involved in the manufacture of
existing systems and the development of new systems and processes. Historically,
during times of economic expansion, competition for such personnel has been
intense, particularly in the San Francisco Bay Area, where our headquarters is
located. At times we have experienced difficulty in attracting new personnel and
if needed, we may not be successful in retaining or recruiting sufficient key
personnel in the future. None of our employees outside Germany is represented by
a labor union and we have never experienced a work stoppage, slowdown or strike.
In Germany, our employees are represented by workers' councils. We consider our
relationships with our employees to be good.

Environmental Matters

We are subject to federal, state, local and international environmental laws
and regulations. These laws, rules and regulations govern the use, storage,
discharge and disposal of hazardous chemicals during manufacturing, research and
development, and sales demonstrations. Neither compliance with federal, state
and local provisions regulating discharge of materials into the environment, nor
remedial agreements or other actions relating to the environment, has had, or is
expected to have, a material effect on our capital expenditures, financial
condition, results of operations or competitive position. However, if we fail to
comply with applicable regulations, we could be subject to substantial liability
for clean up efforts, personal injuries, fines or suspension or cessation of our
operations.

We currently have excess space capacity that we are in the process of
subleasing to offset the lease obligation expenses. In addition, both STEAG and
CFM owned facilities that we have determined are excess space are being offered
for sale.


ITEM 3: LEGAL PROCEEDINGS

We are litigating three ongoing cases against two of our competitors
involving our wet surface preparation intellectual property. We have asserted
claims relating to our U.S. Patent No. 4,911,761 (the "'761 patent") against
a defendant in CFMT and CFM Technologies, Inc. v. YieldUP International Corp.,
Civil Action No. 95-549-RRM, alleging infringement, inducement of infringement,
and contributory infringement. We further asserted claims of U.S. Patent Nos.
4,778,532 (the "'532 patent") and 4,917,123 (the "'123 patent") against this
defendant in a subsequent action, CFMT, Inc. and CFM Technologies. v. YieldUP
International Corp., Civil Action No. 98-790-RRM. In addition, we are both a
defendant and a counterclaim plaintiff in a third litigation, Dainippon Screen
Manufacturing Co., Ltd. and DNS Electronics, LLC v. CFMT, Inc. and CFM
Technologies, Inc., Civil Action No. 97-20270 JW. In this action, the plaintiffs
seek a declaratory judgment of invalidity and unenforceability of the'761
patent and U.S. Patent No. 4,984,597 (the "'597 patent"), and a declaratory
judgment of non-infringement of the '761 patent. We have counterclaimed alleging
infringement, inducement of infringement, and contributory infringement of
certain claims of each of the '761 patent, the '532 patent, the '123 patent, and
the '597 patent.

On September 11, 1995, we brought an action against YieldUP International
Corp. ("YieldUP") in the United States District Court for the District of
Delaware. (YieldUP is now a division of FSI International, Inc.) We seek damages
and a permanent injunction to prevent further infringement. YieldUP has denied
infringement and has asserted, among other things, that the subject patent is
invalid and not infringed. On October 14, 1997, the District Court issued a
decision granting summary judgment in favor of YieldUP on the grounds that the
process used in YieldUP processing equipment does not infringe the '761
patent. The District Court subsequently granted our request for reargument of
the decision. On March 14, 2002, the District Court heard oral argument on the
summary judgment motion. The District Court has not issued any further ruling on
the pending motion.

On December 30, 1998, we filed an additional lawsuit in the United States
District Court for the District of Delaware charging patent infringement of the
'123 and '532 patents by YieldUP. We are seeking a permanent injunction
preventing YieldUP from using, making or selling equipment that violates these
patents and request damages for past infringement. YieldUP has asserted
counterclaims for alleged tortious interference with prospective economic
advantage and defamation and a declaratory judgment that the patents are
invalid, not infringed, and unenforceable due to our alleged inequitable conduct
in obtaining the patents, and seeking compensatory and punitive damages. On
April 4, 2000, the District Court issued an Order granting a YieldUP motion for
summary judgment and denying CFM's cross-motion for summary judgment, and found
that the '532 and '123 patents were both invalid due to lack of enablement.
YieldUP has agreed to withdraw with prejudice the tortious interference and
defamation counts. On June 7, 2001 the District Court issued a judgement in
favor of YieldUP holding that the '532 and '123 patents are unenforceable. We
filed a Notice of Appeal on July 5, 2001,to which YieldUP responded by filing a
motion to dismiss on the grounds that the District Court's judgment is not
final. The Court of Appeals partially remanded the case for the limited purpose
of allowing the District Court to determine whether its June 7, 2001 judgment is
final. YieldUP has filed a motion requesting that the District Court consider,


13


prior to appeal of the District Court's judgment that the '532 and '123 patents
are invalid and unenforceable, whether other of our patents claiming the same
priority date of and related to the '532 and '123 patents, are also
unenforceable. YieldUP has also filed a motion requesting that the District
Court consider, also prior to appeal, whether the case is exceptional and
whether an award of YieldUP's attorneys fees is appropriate. We have filed
oppositions to these motions. The District Court has not ruled on the pending
motions.

In March, 1997, another competitor, Dainippon Screen Mfg. Co. Ltd. and DNS
Electronics LLC (collectively "DNS"), filed a suit against us in the United
States District Court for the Northern District of California. In this action,
DNS requested a court declaration that DNS does not infringe the '761 patent
and that the patent is invalid and unenforceable. DNS also sought monetary
damages and injunctive relief for alleged violations of the Lanham Act, unfair
competition, tortious interference with prospective economic advantage, and
unfair advertising. The causes of action relating to the Lanham Act, unfair
competition, tortious interference with prospective economic advantage, and
unfair advertising were later dismissed without prejudice. We counterclaimed,
alleging infringement by DNS of the '532, '123, and '761 patents. In February,
2000, DNS added additional counts for alleged antitrust and unfair competition
violations, and for declaratory judgment that DNS does not infringe the '597
patent and that this patent is invalid and unenforceable. We counterclaimed
asserting infringement, inducement of infringement, and contributory
infringement of the '597 patent.

As a result of the summary judgment finding of invalidity due to lack of
enablement of the '532 and '123 patents in the YieldUP case, the counts in the
DNS case concerning these two patents were stayed pending further results in the
YieldUP case. The damages issues for all counts in the DNS case were also
bifurcated to be tried after resolution of the liability issues. On November 20,
2000, the Court dismissed DNS's antitrust count on summary judgment.

On July 23,2001, Texas Instruments, Inc. ("TI") filed a Motion to
Intervene for the limited purpose of determining the proper inventorship of the
'761 and '597 patents and, on October 1, 2001, the judge allowed TI to enter the
case. We have settled the claims with TI and TI has been dismissed as a party
from the case.

On March 5, 2002, after a four-week jury trial, a verdict was returned
finding that all six models of DNS's wet surface preparation equipment that
included an "LPD dryer" infringed each of the 20 asserted claims of our '761 and
'597 patents. The jury also explicitly rejected each of DNS's asserted
invalidity defenses. We intend to seek resolution of the remaining DNS
inequitable conduct defense and business tort claims on summary judgment and to
seek prompt entry of a permanent injunction against future acts of infringement
by DNS. Damages remain to be tried. However, should DNS prevail on its
inequitable conduct defense and business tort claims, it is possible that our
'761 and '597 patents could be ruled unenforceable.

Our involvement in any patent dispute, or other intellectual property
dispute or action to protect trade secrets and know-how, could result in a
material adverse effect on our business. Adverse determinations in current
litigation or any other litigation in which we may become involved could subject
the Company to significant liabilities to third parties, require us to grant
licenses to or seek licenses from third parties, and prevent us from
manufacturing and selling our products. Any of these situations could have a
material adverse effect on our business.

We are not aware of any pending legal proceedings against us that,
individually or in the aggregate, would have a material adverse effect on our
business, operating results or financial condition. We may, in the future, be
party to litigation arising in the course of our business, including claims that
we allegedly infringe third party patents, trademarks and other intellectual
property rights. Such claims, even if not meritorious, could result in the
expenditure of significant financial and managerial resources.

facility with our bank from paying future dividends. We intend to retain all
future earnings for use in our business.

Private Placement of Stock

On January 1, 2001, we issued 11,850,000 shares of common stock to STEAG
Electronic Systems AG as part of the consideration for our purchase of the STEAG
Semiconductor Division. The transaction was exempt from registration under the
Securities Act of 1933 (the "Act") by virtue of the exemptions provided in
Section 4(2) of the Act, and Regulation D. There were no underwriters in the
transaction.


ITEM 6. SELECTED CONSOLIDATED FINANCIAL DATA

The following selected consolidated financial data has been derived from
our audited consolidated financial statements. The historical financial data
should be read in conjunction with our consolidated financial statements and
notes thereto. Effective January 1, 2000, we changed our method of accounting
for revenue to implement the revenue recognition provisions of SEC Staff
Accounting Bulletin No. 101 (SAB 101). This change in accounting method effects
the comparability of our financial data for 2000 and 2001 to our reported
results for previous years. See Note 1 of Notes to Consolidated Financial
Statements for an explanation of this change. Unaudited pro forma information is
provided below to show the effect this accounting method change would have had
in years prior to 2000.

On January 1, 2001, we completed the acquisitions of the STEAG
Semiconductor Division and CFM. The acquisitions have been accounted for under
the purchase method of accounting, and the results of operations of the acquired
companies are included in our selected financial data for 2001. During 2001, we
incurred significant charges relating to impairment of long-lived assets,
inventory valuation charges and restructuring costs. These acquisitions and
charges affect the comparability of our financial data for 2001 to our reported
results for previous years. See Management's Discussion and Analysis of
Financial Conditions and Results of Operations and Note 2 of Notes to
Consolidated Financial Statements for further description of these events.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS


The following discussion and analysis of our financial condition and results
of operations should be read in conjunction with "Selected Consolidated
Financial Data" and our consolidated financial statements and related notes
included elsewhere in this document. In addition to historical information, the
discussion in this document contains certain forward-looking statements that
involve risks and uncertainties. Our actual results could differ materially from
those anticipated by these forward-looking statements due to factors, including
but not limited to, those set forth under the caption "Risk Factors that May
Affect Future Results and Market Price of Stock" and elsewhere in this document.

OVERVIEW

We are a leading supplier of semiconductor wafer processing equipment used in
"front-end" fabrication of integrated circuits. Our products include dry strip
equipment, rapid thermal processing ("RTP") equipment, wet surface preparation
equipment, and plasma-enhanced chemical vapor deposition ("PECVD") equipment.
Our integrated circuit manufacturing equipment utilizes innovative technology to
deliver advanced processing capability and high productivity. We provide our
customers with worldwide support through our international technical support
organization, and our comprehensive warranty program.

Our business depends upon capital expenditures by manufacturers of
semiconductor devices. The level of capital expenditures by these manufacturers
depends upon the current and anticipated market demand for such devices. The
semiconductor industry is currently experiencing a severe downturn, which has
resulted in drastic capital spending cutbacks by our customers. Semiconductor
companies continue to reevaluate their capital spending, postpone their new
purchase decisions, and reschedule or cancel existing orders. Declines in demand
for semiconductors deepened throughout each sequential quarter of 2001. In
contrast, the semiconductor industry had one of its best years ever in 2000. The
cyclicality and uncertainties regarding overall market conditions continue to
present significant challenges to us and impair our ability to forecast near
term revenue. Our ability to quickly modify our operations in response to
changes in market conditions is limited. In order to support longer term needs
for our products, we have continued to increase research and development
expenses from previous years. We are dependent upon increases in sales in order
to attain profitability. If our sales do not increase, our current operating
expenses could prevent us from attaining profitability and adversely affect our
financial position and results of operations.

On January 1, 2001, we acquired the semiconductor equipment division of STEAG
Electronic Systems AG (the "STEAG Semiconductor Division"), which consisted of a
number of entities that became our direct or indirect wholly-owned subsidiaries.
At the same time, we acquired CFM Technologies, Inc. ("CFM"). We refer to these
simultaneous acquisitions as "the merger." The merger substantially changed the
size of our company and the nature and breadth of our product lines. The STEAG
Semiconductor Division was a leading supplier of RTP equipment, and both the
STEAG Semiconductor Division and CFM were suppliers of wet surface preparation
equipment. Until 2000, prior to the merger, we derived a substantial majority of
our sales from our Aspen dry strip systems, with our remaining sales derived
primarily from CVD systems, as well as spare parts and maintenance services. In
2000, sales of our Aspen dry strip system and CVD systems comprised 78% and 19%
of our net sales, respectively. In 2001, after the merger, dry strip, RTP, and
wet surface preparation systems sales accounted for 56%, 22%, and 22% of our net
sales, respectively. The merger affects the comparability of our results from
2001 to our results in prior years.

At the time we completed the merger, our industry was entering an economic
slowdown. The merger more than doubled the size of our company, and we faced a
number of challenges in integrating the merged companies. During 2001, we
reduced our workforce by approximately 30%. The acquired businesses had excess
production capacity at the time of merger, and this excess production capacity
was exacerbated by the economic slowdown. During 2001, in light of our business
levels and assessment of the carrying value of our long-lived assets, we took
charges totaling approximately $145.4 million due to the impairment of goodwill,
intangible assets, and other long-lived assets we acquired in the merger. The
merger also had an adverse effect on our gross margins for fiscal 2001. Our
excess production capacity was a large factor affecting our margins, especially
during the later quarters of the year. As a result of the economic slowdown, we
took inventory valuation reserves of approximately $26.4 million during the
year, which were recorded as cost of goods sold.


17



International sales, predominantly to customers based in Europe, Japan and
the Pacific Rim, including Taiwan, Singapore and Korea, accounted for 78% of
total net sales for 2001, 69% of total net sales for 2000 and 71% of total net
sales for 1999. We anticipate that international sales will continue to account
for a significant portion of our sales.

We have substantial research, development and manufacturing facilities in the
United States and Germany, and we have sales and service facilities in a number
of countries around the world. The local currency is the functional currency for
our foreign operations. Gains or losses from translation of foreign operations
are included as a component of stockholders' equity. Foreign currency
transaction gains and losses are recognized in the statement of operations and
have not been material to date.

The transactions that were part of the merger have been accounted for under
the purchase method of accounting. In our acquisition of the STEAG Semiconductor
Division, we issued 11,850,000 shares of our common stock to STEAG Electronic
Systems AG ("SES"). This stock was valued at approximately $124 million for
purchase accounting purposes. We also assumed certain obligations, certain
intercompany indebtedness and contractual payment obligations owed by the
acquired subsidiaries to SES. As a result, at the end of 2001 we had
approximately $44.6 million in debt obligations to SES, including accrued
interest at 6%, due July 2, 2002. In our acquisition of CFM, we issued 4,234,335
shares of our common stock to the former shareholders of CFM. This stock was
valued at approximately $150.2 million for purchase accounting purposes. In
addition, we issued options to acquire 927,427 shares of our common stock upon
our assumption of outstanding options to purchase CFM common stock. These
options were valued at approximately $20.4 million for purchase accounting
purposes. During 2001, in light of our business levels and assessment of the
carrying value of all long-lived assets, we took charges totaling $145.4 million
due to the impairment of goodwill, intangible assets, and other long-lived
assets that we acquired in the merger and charges of $3.7 million for facilities
lease losses for idle facilities.


CRITICAL ACCOUNTING POLICIES

Management's Discussion and Analysis of Financial Condition and Results of
Operations discusses our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires management
to make estimates and assumptions that affect the reported amounts of assets and
liabilities and the 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. On an on-going basis, management evaluates its
estimates and judgements, including those related to inventories, warranty
obligations, customer incentives, bad debts, investments, intangible assets,
income taxes, restructuring costs, retirement benefits, contingencies and
litigation. Management bases its estimates and judgements on historical
experience and on various other factors that are believed to be reasonable under
the circumstances. These form the basis for making judgements about the carrying
values of assets and liabilities that are not readily apparent from other
sources. Actual results may differ from these estimates under different
assumptions or conditions.

We consider certain accounting policies related to revenue recognition,
warranty obligations, inventories, and impairment of long-lived assets as
critical to our business operations and an understanding of our results of
operations. See Note 1 of Notes to the Consolidated Financial Statements for a
summary of our significant accounting policies.

Revenue recognition. We recognize revenue in accordance with SEC Staff
Accounting Bulletin No. 101, Revenue Recognition in Financial Statements (SAB
101).

We derive revenue from two primary sources- equipment sales and spare part
sales. We account for equipment sales as follows: 1.) for equipment sales of
existing products with new specifications or acceptance clauses or to a new
customer, for all sales of new products, and for all sales of our wet surface
preparation products, revenue is recognized upon customer acceptance; 2.) for
equipment sales to existing customers, who have purchased the same equipment
with the same specifications and previously demonstrated acceptance provisions,
the lesser of the fair value of the equipment or the contractual amount billable
upon shipment is recorded as revenue upon title transfer. The remainder is
recorded as deferred revenue and recognized as revenue upon customer acceptance.
From time to time, however, we allow customers to evaluate systems, and since
customers can return such systems at any time with limited or no penalty, we do
not recognize revenue until these evaluation systems are accepted by the
customer. Revenues associated with sales to customers in Japan are recognized
upon customer acceptance, with the exception of sales of our RTP products
through our distributor in Japan, where revenues are recognized upon title
transfer to the distributor. For spare parts, revenue is recognized upon
shipment Service and maintenance contract revenue, which to date has been
insignificant, is recognized on a straight-line basis over the service period of
the related contract.

18



Revenues are difficult to predict, due in part to our reliance on customer
acceptance related to a significant number of our shipments. Any shortfall in
revenue or delay in recognizing revenue could cause our operating results to
vary significantly from quarter to quarter and could result in future operating
losses.

Warranty. Our warranties require us to repair or replace defective product
or parts, generally at a customer's site, during the warranty period at no cost
to the customer. The warranty offered on our systems ranges from 12 months to 36
months depending on the product. We have, as part of certain sales agreements,
offered extended warranties on some products that generally extend the standard
warranty period by up to one year. A provision for the estimated cost of
warranty is recorded as a cost of sales based on our historical costs at the
time of revenue recognition. While our warranty costs have historically been
within our expectations and the provisions we have established, we cannot be
certain that we will continue to experience the same warranty repair costs that
we have in the past. A significant increase in the costs to repair our products
could have a material adverse impact on our operating results for the period or
periods in which such additional costs materialize.

Inventories. Due to the changing market conditions, recent economic
downturn and estimated future requirements, inventory valuation charges of
approximately $26.4 million were recorded in the second half of 2001. This
reserve largely covers inventories for Thermal and Omni products that were
acquired in the merger with the Steag Semiconductor Division and CFM. Given the
downturn in the semiconductor industry, the age of the inventories on hand and
the introduction of new products, we wrote down excess inventories to net
realizable value based on forecasted demand and obsolete inventories that are no
longer used in current production. Actual demand may differ from forecasted
demand and such difference may have a material effect on our financial position
and results of operations. In the future, if our inventory is determined to be
overvalued, we would be required to recognize such costs in our cost of goods
sold at the time of such determination. Although we attempt to accurately
forecast future product demand, any significant unanticipated changes in demand
or technological developments could have a significant impact on the value of
our inventory and our reported operating results. As of December 31, 2001, there
was an allowance for excess and obsolete inventory of approximately $48.0
million.

Impairment of Long-Lived Assets. We assess the impairment of identified
intangibles, long-lived assets and related goodwill whenever events or changes
in circumstances indicate that the carrying value may not be recoverable. Our
judgments regarding the existence of impairment indicators are based on changes
in strategy, market conditions and operational performance of our business.
Future events, including significant negative industry or economic trends, could
cause us to conclude that impairment indicators exist and that long-lived assets
are impaired. Any resulting impairment loss could have a material adverse impact
on our financial condition and results of operations. In assessing the
recoverability of long-lived assets, we must make assumptions regarding
estimated future cash flows and other factors to determine the fair value of the
respective assets. If these estimates or their related assumptions change in the
future, we may be required to record impairment charges for these assets. See
Note 2 in Notes to the Consolidated Financial Statements regarding fiscal 2001
impairment charges.

======= ======= =======



Years Ended December 31, 2001 and 2000

Net Sales. Our net sales for the year ended December 31, 2001 were $230.1
million, compared to net sales of $180.6 million for the year ended December 31,
2000. We estimate that on a pro forma basis for the year ended December 31,
2000, assuming that we had acquired the STEAG Semiconductor Division and CFM on
January 1, 2000, the combined company would have had net sales of $372.7
million, so that net sales in the year 2001 would reflect a decrease of 38.3%
from 2000. Net sales decreased in 2001 primarily due to the economic downturn in
the semiconductor industry and also due to the timing effects of revenue
recognition, where the time-lag between product shipment and customer acceptance
can exceed one year. A significant proportion of products shipped during fiscal
2001 and 2000 from our Thermal and Wet product divisions (operations acquired
from the STEAG Semiconductor Division and CFM) resulted in deferred revenue in
accordance with our revenue recognition policy, due to the complexities of the
equipment shipped and the associated acceptance clauses.

Our total deferred revenue at December 31, 2001 was approximately $136.6
million. We expect deferred revenue to be recognized as revenue in our
consolidated statement of operations in the next six to twelve months. Under the
rules of the purchase method of accounting, deferred revenue relating to sales
by the acquired operations are generally not carried over through the
acquisition. As a result, it will take several quarters of combined operations
before our net sales results normalize and can be compared across reporting
periods.

Gross Margin. Gross margin for the year ended December 31, 2001 was 2.3%, a
decrease from gross margin of 48.4% for the year ended December 31, 2000. The
decrease in gross margin in 2001 was due to several factors. Our costs were
adversely affected by the under absorption of our production facilities, leading
to manufacturing overhead inefficiencies. We currently have excess production
capacity as a result of the drop in sales and bookings combined with our
acquisition of additional production capacity in Germany and Exton, PA as a
result of the merger. Our gross margin in 2001 was also adversely affected by
the write-up of inventory acquired in the merger to fair value, as required by



20


Accounting Principles Board Opinion No. 16 "Business Combinations", in the
amount of $13.8 million, or 6.0 percent of net sales. The effect of this
write-up is expected to continue, to a lesser extent, in future quarters as this
inventory acquired in the merger is sold and recorded as cost of sales. In
addition, our gross margin in 2001 was adversely affected by increased
provisions for excess inventories that we do not believe will be realized based
on our current bookings or forecasted levels of sales, in the amount of $26.4
million, or 11.5 percent of net sales. This provision largely covers inventories
for RTP and wet products that were acquired in the merger. We are also facing
pricing pressure from competitors that is affecting our gross margin.

Our gross margin has varied over the years and will continue to vary based on
multiple factors including, competitive pressures, our product mix, economies of
scale, overhead absorption levels, and costs associated with the introduction of
new products. Our gross margin on international sales, other than sales to
Canon, our distributor in Japan for RTP products, have been substantially the
same as domestic sales. Sales to Canon typically carry a lower gross margin, as
Canon is primarily responsible for RTP sales and support costs in Japan.

Research, Development and Engineering. Research, development and engineering
expenses were $61.1 million, or 26.6% of net sales, for the year ended December
31, 2001, compared to $28.5 million, or 15.8% of net sales, for the year ended
December 31, 2000. The increase in absolute dollars in 2001 was due to
additional personnel and spending resulting from the merger. The increase in
research, development and engineering expense as a percentage of net sales in
2001 compared to 2000 was primarily attributable to decreased sales in 2001.
During 2001, major efforts were made with regard to the improvement of our
current product line of 300 mm tools and the processes they are capable of
running. Improvement of the reliability of the tools was a focal point for
engineering in fiscal 2001.

Selling, General and Administrative. Selling, general and administrative
expenses were $110.8 million, or 48.1% of net sales, for the year ended December
31, 2001, compared with $54.5 million, or 30.1% of net sales, for the year ended
December 31, 2000. The increase in absolute dollars in 2001 was due to
additional personnel and spending added by the merger. Also in 2001, the Company
incurred $8.1 million of severance charges and $6.9 million bad debt charges
recorded in selling, general and administrative expenses. The increase in
selling, general and administrative expenses as a percentage of net sales in
2001 compared to 2000 was primarily attributable to decreased net sales in 2001
and the severance charge.

In-process research and development. In connection with our acquisition of
the STEAG Semiconductor Division, we allocated approximately $5.4 million of the
purchase price to in-process research and development projects. This allocation
represented the estimated fair value based on risk-adjusted cash flows relating
to the incomplete research and development projects. At the date of acquisition,
the development of these projects had not yet reached technological feasibility,
and the research and development in progress had no alternative future uses.
Accordingly, the purchase price allocated to in-process research and development
was expensed as of the acquisition date.

At the acquisition date, the STEAG Semiconductor Division was conducting
design, development, engineering and testing activities associated with the
completion of the Hybrid tool and the Single wafer tool. The projects under
development at the valuation date represent next-generation technologies that
are expected to address emerging market demands for wet processing equipment.

At the acquisition date, the technologies under development were
approximately 60 percent complete based on engineering man-month data and
technological progress. The STEAG Semiconductor Division had spent approximately
$3.3 million on the in-process projects, and expected to spend approximately an
additional $2.4 million to complete all phases of the R&D. Anticipated
completion dates ranged from 10 to 18 months, at which times we expected to
begin benefiting from the developed technologies.

In making our purchase price allocation, we considered present value
calculations of income, an analysis of project accomplishments and remaining
outstanding items, an assessment of overall contributions, as well as project
risks. The value assigned to purchased in-process technology was determined by
estimating the costs to develop the acquired technology into commercially viable
products, estimating the resulting net cash flows from the projects, and
discounting the net cash flows to their present value. The revenue projection
used to value the in-process research and development was based on estimates of
relevant market sizes and growth factors, expected trends in technology, and the
nature and expected timing of new product introductions by us and our
competitors. The resulting net cash flows from such projects are based on our
estimates of cost of sales, operating expenses, and income taxes from such
projects.


21


Aggregate revenues for the developmental STEAG Semiconductor Division
products were estimated to grow at a compounded annual growth rate of
approximately 41 percent for the seven years following introduction, assuming
the successful completion and market acceptance of the major R&D programs. The
estimated revenues for the in-process projects were expected to peak within five
years of acquisition and then decline sharply as other new products and
technologies were expected to enter the market.

The rates utilized to discount the net cash flows to their present value were
based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the projected growth and profitability of
the developmental projects, a discount rate of 23 percent was used to value the
in-process R&D. This discount rate was commensurate with the STEAG Semiconductor
Division stage of development and the uncertainties in the economic estimates
described above.

In connection with the acquisition of CFM, we allocated approximately $4.7
million of the purchase price to an in-process research and development project.
This allocation represented the estimated fair value based on risk-adjusted cash
flows related to one incomplete research and development project. At the date of
acquisition, the development of this project had not yet reached technological
feasibility, and the research and development in progress had no alternative
future use. Accordingly, the purchase price allocated to in-process research and
development was expensed as of the acquisition date.

At the acquisition date, CFM was conducting design, development,
engineering and testing activities associated with the completion of the O3Di
(Ozonated Water Module). The project under development at the valuation date
represents next-generation technology that is expected to address emerging
market demands for more effective, lower cost, and safer resist and oxide
removal processes. At the acquisition date, the technology under development was
approximately 80 percent complete based on engineering man-month data and
technological progress. CFM had spent approximately $0.2 million on the
in-process project, and expected to spend approximately an additional $50,000 to
complete all phases of the research and development. Anticipated completion
dates ranged from 2 to 3 months, at which times we expected to begin benefiting
from the developed technology.

In making our purchase price allocation, we considered present value
calculations of income, an analysis of project accomplishments and remaining
outstanding items, an assessment of overall contributions, as well as project
risks. The value assigned to purchased in-process research and development was
determined by estimating the costs to develop the acquired technology into a
commercially viable product, estimating the resulting net cash flows from the
project, and discounting the net cash flows to their present value. The revenue
projection used to value the in-process research and development was based on
estimates of relevant market sizes and growth factors, expected trends in
technology, and the nature and expected timing of new product introductions by
the Company and its competitors. The resulting net cash flows from the project
is based on management's estimates of cost of sales, operating expenses, and
income taxes from such projects.

Aggregate revenues for the developmental CFM product were estimated for the
five to seven years following introduction, assuming the successful completion
and market acceptance of the major research and development programs. The
estimated revenues for the in-process project was expected to peak within two
years of acquisition and then decline sharply as other new products and
technologies are expected to enter the market.

The rates utilized to discount the net cash flows to their present value were
based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the projected growth and profitability of
the developmental project, a discount rate of 23 percent was used to value the
in-process research and development. This discount rate was commensurate with
CFM's stage of development and the uncertainties in the economic estimates
described above.

If these projects are not successfully developed, the sales and profitability
of the combined company may be adversely affected in future periods.
Additionally, the value of other acquired intangible assets may become impaired.

Amortization of Goodwill and Intangibles. Goodwill and intangibles
represent the purchase price of the STEAG Semiconductor Division and CFM in
excess of identified tangible assets. In connection with the merger, effective
January 1, 2001, we recorded $207.3 million of goodwill and intangible assets,
which were being amortized on a straight-line basis over three to seven years.
We recorded amortization expense of $33.5 million for the year 2001. Upon
adoption of SFAS 142 on January 1, 2002, we will no longer amortize goodwill. We
will continue to amortize the identified intangibles, in an amount estimated to
be $6.7 million for 2002.


22


Impairment of Long-Lived Assets and other charges. In the third and fourth
quarters of 2001, an independent third party performed assessments of the
carrying values of our long-lived assets to be held and used including goodwill,
other intangible assets and property and equipment recorded in connection with
our acquisitions of the STEAG Semiconductor Division and CFM. The assessment was
performed pursuant to SFAS No. 121 as a result of deteriorated market conditions
in the semiconductor industry in general, a reduced demand specifically for the
RTP products and certain wet products acquired in the merger, and revised
projected cash flows for these products in the future. As a result of these
assessments, we recorded a charge of $145.4 million to reduce goodwill,
intangible assets and property and equipment based on the amount by which the
carrying value of these assets exceeded their fair value. Fair value was
determined based on discounted future cash flows.

Interest and Other Income, Net. Interest expense of $3.0 million was
primarily related to interest on our notes payable to SES. Interest income of
$4.4 million resulted from the investment of our cash balances during the year.
We also had other income of $3.7 million which included losses on sales of fixed
assets of $2.3 million and the remainder was due to foreign exchange gains. For
the year ended December 31, 2000, we earned interest income of $6.3 million
which was from the investment of the net proceeds from the sale of common stock
in March 2000.

Provision for Income Taxes. We recorded a tax benefit of $19.0 million for
the year ended December 31, 2001 compared to a tax provision of $1.1 million for
the year ended December 31, 2000. The tax benefit recorded in 2001, resulted
from the release of the deferred tax liability recorded in conjunction with the
purchase of the STEAG Semiconductor Division and CFM. FASB Statement No. 109
requires that a deferred tax liability be recorded to offset the tax impact of
non-deductible identifiable intangible assets recorded as part of purchase
accounting. The deferred tax liability decreases proportionally to any
amortization or write-down of the identifiable intangibles. We recognized a
provision for income taxes at an effective tax rate of 10% during 2000, as we
were able to recognize certain benefits from our prior operating losses. FASB
Statement No. 109 provides for the recognition of deferred tax assets if
realization of such assets is more likely than not. Based upon available data,
which includes our historical operating performance, we have provided a full
valuation allowance against our net deferred tax asset at December 31, 2001, as
the future realization of the tax benefit is not sufficiently assured. We intend
to evaluate the realization of our deferred tax assets on a quarterly basis.


Years Ended December 31, 2000 and 1999

Net Sales. Our net sales for the year ended December 31, 2000 were $180.6
million, representing an increase of $77.1 million, or 74.5%, over net sales of
$103.5 million for the year ended December 31, 1999. Net sales of $180.6 million
in 2000 reflect the company's adoption of SAB 101. Net sales increased in 2000
primarily as a result of a 98.4% increase in unit shipments and a 4.0% increase
in average selling prices that was attributable to semiconductor manufacturers'
need for additional capacity and new technology.

Gross Margin. Gross profit under the adoption of SAB 101 was $87.5 million
for the year ended December 31, 2000, representing 48.4% of net sales, up from
$50.0 million, or 48.3% of net sales, for the year ended December 31, 1999 under
the historical shipment method of recognizing revenue. Our cost of sales
includes labor, materials and overhead. Gross margin increased in 2000 primarily
due to favorable manufacturing overhead efficiencies, as the number of systems
shipped increased 98.4% in 2000 compared to 1999.

Research, Development and Engineering. Research, development and engineering
expenses were $28.5 million, or 15.8% of net sales, for the year ended December
31, 2000, compared to $19.5 million, or 18.9% of net sales, for the year ended
December 31, 1999. The increase was primarily due to compensation and related
benefits, which increased to $12.4 million in 2000 from $9.8 million in 1999,
and engineering materials expense, which increased to $7.0 million in 2000 from
$3.4 million in 1999. The increase in compensation and related benefits expense
was due to increased personnel required to support our anticipated long term
future growth. The decrease in research, development and engineering expense as
a percentage of net sales in 2000 compared to 1999 was primarily attributable to
increased sales in 2000.


23


Selling, General and Administrative. Selling, general and administrative
expenses were $54.5 million, or 30.1% of net sales, for the year ended December
31, 2000, compared with $31.8 million, or 30.7% of net sales, for the year ended
December 31, 1999. The increase was primarily due to compensation and related
benefits, which increased to $32.7 million in 2000 from $22.4 million in 1999
due to increased personnel during 2000, outside services expense, which
increased to $5.1 million in 2000 from $1.8 million in 1999, professional fees,
which increased to $2.5 million in 2000 from $1.4 million in 1999, travel
expense, which increased to $5.4 million in 2000 from $3.2 million in 1999,
building and utility expense, which increased to $5.0 million in 2000 from $3.5
million in 1999, and advertisement expense, which increased to $2.0 million in
2000 from $0.7 million in 1999, all due to our growth. The decrease in selling,
general and administrative expenses as a percentage of net sales in 2000
compared to 1999 was primarily attributable to increased net sales in 2000.

Provision for Income Taxes. We recorded a tax provision of $1,068,000 for
the year ended December 31, 2000 compared to $247,000 for the year ended
December 31, 1999. We recognized provision for income taxes at an effective tax
rate of 10% during 2000, as we were able to recognize certain benefits from our
prior operating losses. In 1999 we did not recognize any tax benefits from our
operating losses and the 1999 tax provision primarily relates to foreign income
tax. FASB Statement No. 109 provides for the recognition of deferred tax assets
if realization of such assets is more likely than not. Based upon available
data, which includes our historical operating performance, we provided a $13.2
million valuation allowance against certain net deferred tax assets at December
31, 2000, as the future realization of the tax benefit was not sufficiently
assured.


Quarterly Results of Operations

The following tables set forth our unaudited consolidated statements of
operations data for each of the eight quarterly periods ended December 31, 2001.
This information should be read in conjunction with our consolidated financial
statements and related notes appearing elsewhere in this annual report. We have
prepared this unaudited consolidated information on a basis consistent with our
audited consolidated financial statements, reflecting all normal recurring
adjustments that we consider necessary for a fair presentation of our financial
position and operating results for the quarters presented. Conclusions about our
future results should not be drawn from the operating results for any quarter.

Our cash and cash equivalents (excluding restricted cash) and short-term
investments were $69.8 million at December 31, 2001, a decrease of $2.4 million
from $72.2 million held as of December 31, 2000. Stockholders' equity at
December 31, 2001 was approximately $141.7 million.

Net cash used in operating activities was $32.3 million for the year ended
December 31, 2001 and $53.1 million for the year ended December 31, 2000. The
net cash used in operations in 2001 was primarily attributable to the net loss
of $336.7 million and a decrease in accrued liabilities of $25.4 million and
accrued payables of $20.7 million. These uses of cash were offset by non-cash
impairment of long-lived assets and other charges of $150.7 million and
depreciation and amortization of goodwill and intangibles of $33.5 million, an
increase in deferred revenue of $95.9 million, decrease in accounts receivable
of $50.4 million, inventory valuation charges of $26.4 million and acquired
in-process research and development of $10.1 million.

The net cash used in operations in 2000 was primarily attributable to the
net income of $1.5 million, deferred taxes of $6.4 million, an increase in
restricted cash of $32.0 million, an increase in accounts receivable of $39.6
million, an increase in inventories of $30.1 million, an increase in prepaid
expenses and other assets of $6.7 million, offset by the cumulative effect of a
change in accounting principle of $8.1 million, non-cash depreciation and
amortization of $4.5 million, an increase in deferred revenue of $31.3 million,
an increase in accounts payable of $6.6 million and an increase in accrued
liabilities of $11.4 million.

The net cash of $9.5 million used in operations in 1999 was primarily
attributable to the net loss of $0.8 million, an increase in accounts receivable
of $11.9 million and an increase in inventories of $14.8 million, offset by
non-cash depreciation and amortization of $4.8 million, a decrease in prepaid
expenses and refundable income taxes of $2.7 million, an increase in accounts
payable of $5.1 million and an increase in accrued liabilities of $5.4 million.

Net cash provided by investing activities was $63.3 million for the year
ended December 31, 2001 which consisted of the sale of $58.3 million of
investments and cash acquired from the acquisition of STEAG and CFM of $38.0
million offset by the purchase of $17.2 million of property and equipment and
$16.3 million of investments.

Net cash used in investing activities in 2000 was $56.5 million which
consisted of the purchase of $59.4 million of investments and $9.0 million of
property and equipment offset by the sale of $12 million of investments. Net
cash provided by investing activities in 1999 included the collection of a $3.7
million note receivable from our then chief executive officer, and the sale of
$8.1 million of short-term investments, offset by the purchase of $3.3 million
of property and equipment.

Net cash provided by financing activities was $9.6 million in 2001, primarily
from $9.0 million borrowings against lines of credit, $3.6 million proceeds from
stock plans and $2.7 million of interest accrued on the notes payable to SES,
offset by the repayment of $4.9 million against our line of credit.

Net cash provided by financing activities was $126.1 million in 2000,
primarily from $122.8 million net proceeds from the issuance of common stock and
$6.4 million proceeds from stock plans, offset by the repayment of $3.0 million
against our line of credit. Net cash provided by financing activities was $6.0
million in 1999, primarily from the $3.0 million net proceeds from the issuance
of common stock under our employee stock purchase plan and our stock option plan
and borrowings of $3.0 million against our $15.0 million line of credit.

As a result of our acquisition of the STEAG Semiconductor Division at the
beginning of 2001, we owe SES a total of approximately $44.6 million under two
promissory notes which bear interest at 6.0% per year and are due July 2, 2002.
One promissory note, in the amount of $26.9 million, is secured by an
irrevocable standby letter of credit issued by Silicon Valley Bank, which is in
turn secured by restricted cash on our balance sheet in the amount of $27.3
million. This obligation had originally been due on July 2, 2001. On November 5,
2001, SES agreed to extend the maturity date to July 2, 2002, and the interest
accrued through July 2, 2001 was capitalized and added to the principal under
the extended note. The note contains certain covenants, and we have been in
compliance with them. The second promissory note, in the amount of 19.2 million
EURO (approximately $17.1 million), is secured by the accounts receivable of two
of our acquired subsidiaries, Mattson Thermal Products GmbH, Dornstadt, Germany,
and Mattson Wet Products GmbH, Pliezhausen, Germany. This note contains
covenants and requires us to maintain certain balances, including a minimum
amount of applicable accounts receivable of at least 17.9 million EURO
(approximately $15.9 million) at our relevant subsidiaries. We have been in
compliance with all of these covenants.

As of December 31, 2001, we have non-cancelable operating lease commitments
of $45.8 million.

26



We have made loans to certain current and former executive officers, in an
aggregate amount of approximately $670,000. These loans are described in the
section captioned "Certain Relationships and Related Transactions."

Our Japanese subsidiary has entered into a credit line with Bank of
Tokyo-Mitsubishi in the amount of 900 million Yen (approximately $6.9 million),
secured by trade accounts receivable. The line bears interest at a per annum
rate of TIBOR plus 75 basis points, which is approximately 0.81% at December 31,
2001. The term of the line is through June 20, 2002. We have guaranteed the
line. At December 31, 2001, the borrowing on this line was 601.7 million Yen
(approximately $4.6 million). During 2000, one of the subsidiaries we acquired
as part of the STEAG Semiconductor Division entered into a two-year revolving
line of credit with a bank in Japan in the amount of 500 million Yen
(approximately $3.8 million), under which 450 million Yen (approximately $3.5
million) was borrowed. It bore interest at a per annum rate of 1.96% through
March 2001 and thereafter at a rate of 1.75%, and was secured by a letter of
credit in the amount of $5.1 million, which required us to maintain a restricted
cash balance in the same amount. These borrowings were repaid in full in
December 2001, and the line of credit was cancelled. This resulted in an
increase in our unrestricted cash by approximately $1.6 million.

On March 8, 2000 we completed a public offering of 3,000,000 shares of our
common stock. The public offering price was $42.50 per share. On March 16, 2000,
the underwriters exercised a right to purchase an additional 90,000 shares to
cover over-allotments. The net proceeds of approximately $122.8 million were
raised for general corporate purposes, principally working capital requirements
and capital expenditures.

On March 29, 2002 we entered into a one-year revolving line of credit with
a bank in the amount of $20.0 million. The line of credit will expire on March
29, 2003, if not extended by then. All borrowings under this line will bear
interest at a per annum rate equal to the bank's prime rate plus 125 basis
points. The line of credit is secured by a blanket lien on all domestic assets
including intellectual property. The line of credit requires the Company to
satisfy certain quarterly financial covenants, including maintaining a minimum
quick ratio, minimum tangible net worth and meeting minimum revenue targets.

Based on current projections, we believe that our current cash and investment
positions will be sufficient to meet our anticipated cash needs for working
capital and capital expenditures for at least the next 12 months. Our primary
source of liquidity is our existing unrestricted cash balance and cash generated
by our operations. During 2001, we had operating losses, and used net cash in
our operating activities. Our operating plans are based on and require that we
reduce our operating losses, control our expenses, manage our inventories, and
collect our accounts receivable balances. In this market downturn, we are
exposed to a number of challenges and risks, including delays in payments of our
accounts receivable by our customers, and postponements or cancellations of
orders. Postponed or cancelled orders can cause us to have excess inventory and
underutilized manufacturing capacity. If we are not able to significantly reduce
our present operating losses over the upcoming quarters, our operating losses
could adversely affect our cash and working capital balances, and we may be
required to seek additional sources of financing.

We may need to raise additional funds in future periods through public or
private financing, or other sources, to fund our operations. We may not be able
to obtain adequate or favorable financing when needed. Failure to raise capital
when needed could harm our business. If we raise additional funds through the
issuance of equity securities, the percentage ownership of our stockholders
would be reduced, and these equity securities may have rights, preferences or
privileges senior to our common stock. Any additional equity financing may be
dilutive to stockholders, and debt financing, if available, may involve
restrictive covenants on our operations and financial condition.


New Accounting Pronouncements

On June 29, 2001, the Financial Accounting Standard Board (FASB) approved
for issuance SFAS No. 141, "Business Combinations", and SFAS No. 142, "Goodwill
and Other Intangible Assets". Major provisions of these Statements are as
follows: all business combinations initiated after June 30, 2001 must use the
purchase method of accounting; the pooling of interest method of accounting is
prohibited except for transactions initiated before July 1, 2001; intangible
assets acquired in a business combination must be recorded separately from
goodwill if they arise from contractual or other legal rights or are separable
from the acquired entity and can be sold, transferred, licensed, rented or
exchanged, either individually or as part of a related contract, asset or
liability; goodwill and intangible assets with indefinite lives are not
amortized but are tested for impairment annually using a fair value approach,
except in certain circumstances, and whenever there is an impairment indicator;


27


other intangible assets will continue to be valued and amortized over their
estimated lives; in-process research and development will continue to be written
off immediately; all acquired goodwill must be assigned to reporting units for
purposes of impairment testing and segment reporting; effective January 1, 2002,
existing goodwill and certain intangible assets will no longer be subject to
amortization. Goodwill arising between July 1, 2001 and December 31, 2001 will
not be subject to amortization.

Upon adoption of SFAS No. 142, on January 1, 2002, the Company no longer
amortizes goodwill, thereby eliminating annual goodwill amortization of
approximately $3.9 million, based on anticipated amortization for 2002. The
Company will continue to amortize the identified intangibles, which is estimated
to be $6.7 million for 2002. Amortization of goodwill and intangibles for the
year ended December 31, 2001 was approximately $33.5 million including amounts
related to the amortization of goodwill and intangibles of CFM and the STEAG
Semiconductor Division which became impaired.

In August 2001, the FASB issued Statement of Financial Accounting Standards
No. 143, "Accounting for Asset Retirement Obligations," ("SFAS 143"). SFAS 143
addresses accounting and reporting for obligations associated with the
retirement of tangible long-lived assets and the associated asset retirement
costs. This Statement requires that the fair value of a liability for an asset
retirement obligation be recognized in the period in which it is incurred if a
reasonable estimate of fair value can be made. The associated asset retirement
costs are capitalized as part of the carrying amount of the long-lived asset.
The liability is accreted to its present value each period while the cost is
depreciated over its useful life. SFAS 143 is effective for financial statements
issued for fiscal years beginning after June 15, 2002. The Company believes that
the adoption of SFAS 143 will not have a significant effect on its financial
position, results of operations or cash flows.

In October 2001, the FASB issued Statement of Financial Accounting Standards
No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets,"
("SFAS 144"). SFAS 144, which replaces SFAS 121 "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," requires
long-lived assets to be measured at the lower of carrying amount or fair value
less the cost to sell. SFAS 144 also broadens disposal transactions reporting
related to discontinued operations. SFAS 144 is effective for financial
statements issued for fiscal years beginning after December 15, 2001. The
Company believes that the adoption of SFAS 144 will not have a significant
effect on its financial position, results of operations, or cash flows.


Mergers and Acquisitions

On June 27, 2000, we entered into a definitive Strategic Business
Combination Agreement, subsequently amended on December 15, 2000 and November 5,
2001("Combination Agreement") to acquire eleven direct and indirect subsidiaries
comprising the semiconductor equipment division of STEAG Electronic Systems AG
("the STEAG Semiconductor Division"), and we entered into an Agreement and Plan
of Merger ("Plan of Merger") to acquire CFM Technologies, Inc. ("CFM"). Both
transactions were completed simultaneously on January 1, 2001.

Under the Combination Agreement, we issued to STEAG Electronic Systems AG
("SES") 11,850,000 shares of common stock, valued at approximately $124 million
as of the date of the amended Combination Agreement. We also paid SES $100,000
in cash, assumed certain obligations of SES and STEAG AG, the parent company of
SES, and assumed certain intercompany indebtedness and obligations owed by the
acquired subsidiaries to SES. We reimbursed SES $3.3 million in acquisition
related costs in April 2001. At December 31, 2001, we owed SES approximately
$44.6 million (including accrued interest), under two secured promissory notes.
One note is in the principal amount of $26.9 million, and the other is in the
principal amount of 19.2 million EUROS (approximately $17.1 million as of
December 31, 2001). Each note bears interest at 6% per annum, and is due July 2,
2002. The acquisition has been accounted for under the purchase method of
accounting, and the results of operations of the STEAG Semiconductor Division
are included in our condensed consolidated statement of operations from the date
of acquisition. The purchase price of this acquisition was $148.6 million, which
included $6.2 million of direct acquisition related costs (including the amount
reimbursed to SES).

Under the Plan of Merger with CFM, we agreed to acquire CFM in a
stock-for-stock merger in which we issued 4,234,335 shares of our common stock,
valued at approximately $150.2 million. In addition, we assumed all outstanding
CFM stock options, which resulted in our issuance of options to acquire 927,457
shares of our common stock, valued at approximately $20.4 million. The merger
has been accounted for under the purchase method of accounting and the results
of operations of CFM are included in our consolidated statement of operations
from the date of acquisition. The purchase price of the acquisition of CFM was
$174.6 million, which included $4.0 million of direct acquisition related costs.


28


Under the Combination Agreement and the Plan of Merger, we also agreed to
grant options to purchase 850,000 shares of our common stock to employees of the
STEAG Semiconductor Division and options to purchase 500,000 shares of our
common stock to employees of CFM subsequent to the closing of the transactions.
These options are not included in the purchase price of the STEAG Semiconductor
Division or CFM.

As a result of our acquisition of the STEAG Semiconductor Division, SES holds
approximately 32% of our common stock and currently has two representatives on
our board of directors. As part of the acquisition, we entered into several
transition services agreements with SES, under which SES agreed to provide
specified payroll, communications, accounting information and intellectual
property administration services to certain of our German subsidiaries for a
term of one year. In 2001, we paid to SES approximately $988,000 in connection
with the purchase of services or supplies pursuant to the transition services
agreements. In addition, we have a manufacturing supply contract with a company
affiliated with SES, under which we had the right to utilize manufacturing and
assembly services based on an hourly rate. For 2001, we purchased $3.7 million
worth of such manufacturing and assembly services.

In February 2001, we announced plans to divest our single-wafer RT-CVD
business unit, previously known as STEAG CVD Systems. The business unit, which
was acquired as part of the STEAG Semiconductor Division, included lamp-based
RT-CVD tools that did not fit with our strategic roadmap for thermal and CVD
products.

In April 2001, we acquired 97% of the outstanding shares of R.F.
Services, Inc. for a cash price of $928,800 (including
acquisition-related costs of $41,500). Brad Mattson, former Chief
Executive Officer of the Company, owned a majority of the outstanding
shares of R.F. Services, Inc. and served as a director of that company.


RISK FACTORS THAT MAY AFFECT FUTURE RESULTS AND MARKET PRICE OF STOCK

The Semiconductor Equipment Industry is Cyclical, is Currently Experiencing a
Severe and Prolonged Downturn, and Causes Our Operating Results to Fluctuate
Significantly.

The semiconductor industry is highly cyclical and has historically
experienced periodic downturns, whether the result of general economic changes
or capacity growth temporarily exceeding growth in demand for semiconductor
devices. During periods of declining demand for semiconductor manufacturing
equipment, customers typically reduce purchases, delay delivery of products
and/or cancel orders. Increased price competition may result, causing pressure
on our net sales, gross margin and net income. We are experiencing
cancellations, delays and push-outs of orders, which reduce our revenues, cause
delays in our ability to recognize revenue on the orders and reduce backlog.
Further order cancellations, reductions in order size or delays in orders will
materially adversely affect our business and results of operations.

Following the very strong year in 2000, the semiconductor industry is now
in the midst of a significant and prolonged downturn, and we and other industry
participants are experiencing lower bookings, significant push outs and
cancellations of orders. The severity and duration of the downturn are unknown,
but is impairing our ability to sell our systems and to operate profitably. If
demand for semiconductor devices and our systems remains depressed for an
extended period, it will seriously harm our business.

As a result of the acquisition of the STEAG Semiconductor Division and CFM
at the beginning of 2001, we are a larger, more geographically diverse company,
less able to react quickly to the cyclicality of the semiconductor business,
particularly in Europe and other regions where restrictive laws relating to
termination of employees prohibit us from quickly reducing costs in order to
meet the downturn. Accordingly, during this latest downturn we have been unable
to reduce our expenses quickly enough to avoid incurring a loss. For the fiscal
year ended December 31, 2001, our net loss was $336.7 million, compared to net
income of $1.5 million for the year ended December 31, 2000. The net loss in
2001 reflected the impact of our decline in net sales, and unusual charges of
$209.1 million, including impairment charges, effects of APB 16 inventory
charges, inventory valuation charges and write-downs, restructuring costs and
in-process research and development write-offs. If our actions to date are
insufficient to effectively align our cost structure with prevailing market
conditions, we may be required to undertake additional cost-cutting measures,
and may be unable to continue to invest in marketing, research and development
and engineering at the levels we believe are necessary to maintain our
competitive position. Our failure to make these investments could seriously harm
our long-term business prospects.


29



We are Exposed to the Risks Associated with Industry Overcapacity, Including
Reduced Capital Expenditures, Decreased Demand for Our Products and the
Inability of Many of Our Customers to Pay for Our Products.

As a result of the recent economic downturn, inventory buildups in
telecommunication products and slower than expected personal computer sales have
resulted in overcapacity of semiconductor devices and has caused semiconductor
manufacturers to experience cash flow problems and reduce their capital
spending. As our business depends in significant part upon capital expenditures
by manufacturers of semiconductor devices, including manufacturers that open new
or expand existing facilities, continued overcapacity and reductions in capital
expenditures by our customers could cause further delays or decreased demand for
our products. If existing fabrication facilities are not expanded or new
facilities are not built, demand for our systems may not develop or increase,
and we may be unable to generate significant new orders for our systems. If we
are unable to develop new orders for our systems, we will not achieve
anticipated net sales levels.

In addition, many semiconductor manufacturers are continuing to forecast
that revenues in the short-term will remain flat or lower than in previous
high-demand years, and we believe that some customers may experience cash flow
problems. As a result, if customers are not successful generating sufficient
revenue or securing alternative financing arrangements, we may be unable to
close sales or collect accounts receivables from such customers or potential
customers, and may be required to take additional reserves against our accounts
receivables.

The Merger with STEAG and CFM May Fail to Achieve Beneficial Synergies and We
May Be Unable to Efficiently Integrate the Operations of Our Acquisitions.

We entered into the merger transaction with the expectation that it would
result in beneficial synergies between and among the semiconductor equipment
businesses of the three combined companies. Achieving these anticipated
synergies and their potential benefits would depend on a number of factors, some
of which include:

* our ability to timely develop new products and integrate the products
and sales efforts of the combined company; and

* competitive conditions and cyclicality in the semiconductor
manufacturing process equipment market.

If we are able to realize the anticipated benefits of these acquisitions,
the operations of STEAG and CFM must be integrated and combined efficiently.
Although we have commenced these integration activities, the process of
integrating supply and distribution channels, computer and accounting systems
and other aspects of operations, while managing a larger entity, has presented
and is expected to continue to present a significant challenge to our
management. In addition, we have incurred substantial restructuring costs in
order to achieve desired synergies of the transactions, including severance
costs associated with headcount reductions due to duplication; and asset
write-offs associated with manufacturing and facility consolidations. We may
incur additional costs associated with improving existing and implementing new
operational and financial systems, procedures and controls to fully integrate
the three businesses. The dedication of management resources to the integration
has detracted, and may continue to detract, attention from the day-to-day
business. The difficulties of integration are increased by the necessity of
combining personnel with disparate business backgrounds, combining different
corporate cultures and utilizing incompatible financial systems. We may incur
additional costs associated with these activities, which could materially reduce
our short-term earnings.

Even with the integrated operations, there can be no assurance that the
anticipated synergies will be achieved. The failure to achieve such synergies
could have a material adverse effect on our business, results of operations, and
financial condition.


30


We Will Need to Improve or Implement New Systems, Procedures and Controls.

The integration of STEAG and CFM and their operational and financial
systems and controls has placed a significant strain on our management
information systems and our administrative, operational and financial resources.
To efficiently manage the combined company, we must improve our existing and
implement new operational and financial systems, procedures and controls. Since
the merger, we have commenced integration of the businesses, systems and
controls of the three companies, however, each business has historically used a
different financial system, and the resulting integration and consolidation has
placed and will continue to place substantial demands on our management
resources. Improving or implementing new systems, procedures and controls may be
costly, and may place further burdens on our management and internal resources.
If we are unable to improve our existing or implement new systems, procedures
and controls in a timely manner, our business could be seriously harmed.

Our Results of Operations May Suffer if We Do Not Effectively Manage Our
Inventory.

To achieve commercial success with our product lines, we will need to
manage our inventory of component parts and finished goods effectively to meet
changing customer requirements. Some of our products and supplies have in the
past and may in the future become obsolete while in inventory due to rapidly
changing customer specifications. For example, in the quarters ended September
30, 2001 and December 31, 2001, we took inventory valuation charges of $26.4
million. If we are not successfully able to manage our inventory, including our
spare parts inventory, we may need to write off unsaleable or obsolete
inventory, which would adversely affect our results of operations.

Warranty Claims in Excess of Our Projections Could Seriously Harm Our Business.

We offer a warranty on our products. The cost associated with our warranty
is significant, and in the event our projections and estimates of this cost are
inaccurate our financial performance could be seriously harmed. In addition, if
we experienced product failures at an unexpectedly high level, our reputation in
the marketplace could be damaged and our business would suffer.

We May Need Additional Capital, Which May Not Be Available and
Which Could Be Dilutive to Existing Stockholders.

Based on current projections, we believe that our current cash and
investments along with cash generated through operations will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures for
the next 12 months. Management's projections are based on our ability to manage
inventories and collect accounts receivable balances in this market downturn. If
we are unable to manage our inventories or accounts receivable balances, or if
we otherwise experience higher operating costs or lower revenue than we
anticipate, then we may be required to seek alternative sources of financing. We
may need to raise additional funds in future periods through public or private
financing or other sources to fund our operations. We may not be able to obtain
adequate or favorable financing when needed. If we fail to raise capital when
needed, we would be unable to continue operating our business as we plan, or at
all. If we raise additional funds through the issuance of equity securities, the
percentage ownership of our stockholders would be reduced. In addition, any
future equity securities may have rights, preferences or privileges senior to
our common stock. Furthermore, debt financing, if available, may involve
restrictive covenants on our operations.

If We Are Unable to Repay Amounts Due to STEAG in July 2002, Our Business Could
Be Harmed.

In connection with our acquisition of the STEAG Electronics Division, we
assumed certain obligations to STEAG Electronic Systems AG ("SES"), including
certain intercompany indebtedness owed by the acquired subsidiaries to SES, in
exchange for a secured promissory note in the principal amount of $26.9 million,
with an interest rate of 6%. This note is secured by restricted cash in the
amount of $26.9 million. We are also obligated to pay SES approximately Euro
19.2 million (approximately $17.1 million as of December 31, 2001) under a
second promissory note, which is secured by accounts receivable of two of our
subsidiaries in Germany. As this second note is payable in Euros, we have
exposure for exchange rate volatility. Under both of these obligations,
including accrued interest, we owe approximately $44.6 million as of December
31, 2001 to SES, which is due on July 2, 2002. At the due date, we will be
required to repay these obligations in full. If we are unable to repay the
amounts due on the due date, STEAG could foreclose on the loans, resulting in
significant harm to our business and financial condition.

Our Financial Reporting may be Delayed and Our Business may be Harmed if Our
Independent Public Accountant, Arthur Andersen LLP, is Unable to Perform
Required Services.

On March 14, 2002, our independent public accounting firm, Arthur Andersen
LLP, was indicted for alleged obstruction of justice arising from the federal
government's investigation of Enron Corporation. Arthur Andersen pleaded not
guilty to the charges, and indicated that it intends to defend itself
vigorously. As a public company, we are required to file with the SEC periodic
financial statements audited or reviewed by an independent, certified public
accountant. The SEC has announced that it will continue accepting financial
statements audited by Arthur Andersen, and interim financial statements reviewed
by it, so long as Arthur Andersen is able to make certain representations to its
clients. Our ability to make timely SEC filings could be impaired if the SEC
ceases accepting financial statements audited by Arthur Andersen, if Arthur
Andersen becomes unable to make required representations to us or if for any
other reason Arthur Andersen is unable to perform required audit-related
services for us in a timely manner. This in turn could damage or delay our
access to the capital markets, and could be disruptive to our operations and
affect the price and liquidity of our securities. Certain investors, including
significant mutual funds and institutional investors, may choose not to hold or
invest in securities of issuers that do not have current financial reports
available. In such a case, we would promptly seek to engage other independent
public accountants or take such other actions as may be necessary to enable us
to timely file required financial reports. In addition, relief that may
otherwise be available to shareholders under the federal securities laws against
auditing firms may not be available as a practical matter against Arthur
Andersen should it cease to operate or become financially impaired.


New Accounting Guidance Under SAB 101 Has Resulted in Delayed
Recognition of Our Revenue.

In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), Revenue Recognition in Financial
Statements. SAB 101 provides guidance on applying generally accepted accounting
principles to revenue recognition issues in financial statements. Among other
things, SAB 101 has resulted in a change from the established practice of
recognizing revenue at the time of shipment of a system, and instead delaying
revenue recognition in part or totally until the time of customer acceptance. We
adopted SAB 101 effective in the fourth quarter of fiscal 2000, retroactive to
January 1, 2000, with the impact recorded as a cumulative effect in the first
quarter of 2000. In some situations, application of this accounting guidance
delays the recognition of revenue that would otherwise have been recognized in
earlier periods. As a result, our reported revenue may fluctuate more widely and
reported revenue for a particular fiscal period might not meet the expectations
of financial analysts or investors. A delay in recognition of revenue resulting
from application of this guidance, while not affecting our cash flow, could
adversely affect our results of operations, which could cause the value of our
common stock to fall.


We Depend on Large Purchases From a Few Customers, and Any Loss, Cancellation,
Reduction or Delay in Purchases By, or Failure to Collect Receivables From,
These Customers Could Harm Our Business.

Currently, we derive most of our revenues from the sale of a relatively
small number of systems to a relatively small number of customers, which makes
our relationship with each customer critical to our business. The list prices on
our systems range from $500,000 to over $2.2 million. Our lengthy sales cycle
for each system, coupled with customers' capital budget considerations, make the
timing of customer orders uneven and difficult to predict. In addition, our
backlog at the beginning of a quarter is not expected to include all orders
required to achieve our sales objectives for that quarter. As a result, our net
sales and operating results for a quarter depend on our ability to ship orders
as scheduled during that quarter as well as obtain new orders for systems to be
shipped in that same quarter. During the fourth quarter of 2001, we experienced
lower bookings, significant push outs and cancellation of orders. Any delay in
scheduled shipments or in acceptances of shipped products would delay our
ability to recognize revenue, collect outstanding accounts receivable, and would
materially adversely affect our operating results for that quarter. A delay in a
shipment or customer acceptance near the end of a quarter may cause net sales in
that quarter to fall below our expectations and the expectations of market
analysts or investors.

If we are unable to collect a receivable from a large customer, our
financial results will be negatively impacted. Our list of major customers
changes substantially from year to year, and we cannot predict whether a major
customer in one year will make significant purchases from us in future years.
Accordingly, it is difficult for us to accurately forecast our revenues and
operating results from year to year. If we are unable to collect a receivable
from a large customer, our financial results will be negatively impacted.


32


Our Quarterly Operating Results Fluctuate Significantly and Are Difficult to
Predict, and May Fall Short of Anticipated Levels, Which Could Cause Our Stock
Price to Decline.

Our quarterly revenue and operating results have varied significantly in
the past and are likely to vary significantly in the future, which makes it
difficult for us to predict our future operating results. This fluctuation is
due to a number of factors, including:

o cyclicality of the semiconductor industry;

o delays, cancellations and push-outs of orders by our customers;

o delayed payments of invoices by our customers;

o size and timing of sales and shipments of our products;

o entry of new competitors into our market, or the announcement of new
products or product enhancements by competitors;

o sudden changes in component prices or availability;

o variability in the mix of products sold;

o manufacturing inefficiencies caused by uneven or unpredictable order
patterns, reducing our gross margins;

o higher fixed costs due to increased levels of research and development
or patent litigation costs; and

o successful expansion of our worldwide sales and marketing
organization.

A substantial percentage of our operating expenses are fixed in the short
term and we may be unable to adjust spending to compensate for an unexpected
shortfall in revenues. As a result, any delay in generating or recognizing
revenues could cause our operating results to be below the expectations of
market analysts or investors, which could cause the price of our common stock to
decline.


We Incurred Net Operating Losses for the Fiscal Years 1998, 1999 and 2001. We
May Not Achieve or Maintain Profitability on an Annual Basis, and If We Do Not,
We May Not Utilize Deferred Tax Assets.

We incurred net losses of approximately $22.4 million for the year ended
December 31, 1998, $0.8 million for the year ended December 31, 1999, and $336.7
million for the year ended December 31, 2001. We expect to continue to incur
significant research and development and selling, general and administrative
expenses and may not return to profitability in 2002. We will need to generate
significant increases in net sales to achieve and maintain profitability on an
annual basis, and we may not be able to do so. Our ability to realize our
deferred tax assets in future periods will depend on our ability to achieve and
maintain profitability on an annual basis.


As a Result of the Industry Downturn, We Have Implemented a Restructuring and
Workforce Reductions, Which May Adversely Affect the Morale and Performance of
our Personnel and our Ability to Hire New Personnel.

In connection with our efforts to streamline operations, reduce costs and
bring our staffing and structure in line with current demand for our products,
we recently restructured our organization and reduced our workforce by 466
full-time positions and 103 consultant positions in 2001. We have incurred costs
of $8.1 million associated with the workforce reduction related to severance and
other employee-related costs in 2001, and may incur further costs if additional
restructuring is needed to right size our business further or bring our costs
down to respond to continued industry and economic slowdowns. Our restructuring
may also yield unanticipated consequences, such as attrition beyond our planned
reduction in workforce and loss of employee morale and decreased performance. In
addition, the recent trading levels of our common stock have decreased the value
of our stock options granted to employees pursuant to our stock option plan. As
a result of these factors, our remaining personnel may seek employment with
larger, more established companies or companies they perceive as having less
volatile stock prices. Continuity of personnel can be an important factor in the
successful sales of our products and completion of our development projects, and
ongoing turnover in our sales and research and development personnel could
materially and adversely impact our sales, development and marketing efforts. We
believe that hiring and retaining qualified individuals at all levels is
essential to our success, and there can be no assurance that we will be
successful in attracting and retaining the necessary personnel.


33


Our Lengthy Sales Cycle Increases Our Costs and Reduces the Predictability of
Our Revenue.

Sales of our systems depend upon the decision of a prospective customer to
increase or replace manufacturing capacity, typically involving a significant
capital commitment. Accordingly, the decision to purchase our systems requires
time consuming internal procedures associated with the evaluation, testing,
implementation, and introduction of new technologies into our customers'
manufacturing facilities. Potential new customers evaluate the need to acquire
new semiconductor manufacturing equipment infrequently. Even after the customer
determines that our systems meet their qualification criteria, we experience
delays finalizing system sales while the customer obtains approval for the
purchase and constructs new facilities or expands its existing facilities. We
may expend significant sales and marketing expenses during this evaluation
period. The time between our first contact with a customer regarding a specific
potential purchase and the customer's placing its first order may last from nine
to twelve months or longer. In this difficult economic climate, the average
sales cycle has lengthened even further and is expected to continue to make it
difficult to accurately forecast future sales. If sales forecasted from a
specific customer for a particular quarter are not realized, we may experience
an unplanned shortfall in revenues and our quarterly and annual revenue and
operating results may fluctuate significantly from period to period.


We Are Highly Dependent on Our International Sales, and Face Significant
Economic and Regulatory Risks Because a Majority of Our Net Sales Are From
Outside the United States.

Asia has been a particularly important region for our business, and we
anticipate that it will continue to be important as we expand our sales and
marketing efforts by opening an office in China. Our sales to customers located
in Taiwan, Japan, and other Asian countries accounted for 47% of our total sales
in 2001, 54% in 2000, and 59% in 1999. During 2001, Europe also emerged as an
important region for our business, contributing 31% of our sales. During 2000
and 1999, sales to customers in Europe accounted for 14% and 11%, respectively.
Our international sales accounted for 78% of our total net sales in 2001, 69% in
2000 and 71% in 1999 and we anticipate international sales will continue to
account for a significant portion of our future net sales. Because of our
continuing dependence upon international sales, however, we are subject to a
number of risks associated with international business activities, including:

o unexpected changes in law or regulations resulting in more burdensome
governmental controls, tariffs, restrictions, embargoes, or export
license requirements;

o exchange rate volatility;

o the need to comply with a wide variety of foreign and U.S. export
laws;

o political and economic instability, particularly in Asia;

o differing labor regulations;

o reduced protection for intellectual property;

o difficulties in accounts receivable collections;

o difficulties in managing distributors or representatives;

o difficulties in staffing and managing foreign subsidiary operations;
and

o changes in tariffs or taxes.


34


In the U.S., our sales to date have been denominated primarily in U.S.
dollars, while our sales in Japan are usually denominated in Japanese Yen. Our
sales to date in Europe have been denominated in various currencies, currently
primarily U.S. dollars and the Euro. Our sales in foreign currencies are subject
to risks of currency fluctuation. Although we have, adopted a foreign currency
hedging program, to date we have engaged in immaterial amounts hedging
transactions or used derivative financial instruments to mitigate our currency
risks. For U.S. dollar sales in foreign countries, our products become less
price-competitive where the local currency is declining in value compared to the
dollar. This could cause us to lose sales or force us to lower our prices, which
would reduce our gross margins.

In addition, we are exposed to the risks of operating a global business,
and maintain certain manufacturing facilities in Germany. Managing our global
operations presents challenges, including varying business conditions and
demands, political instability, export restrictions and fluctuations in interest
and currency exchange rates.


We May Not Achieve Anticipated Revenue Growth if We Are Not Selected as "Vendor
Of Choice" for New or Expanded Fabrication Facilities or If Our Systems and
Products Do Not Achieve Broader Market Acceptance.

Because semiconductor manufacturers must make a substantial investment to
install and integrate capital equipment into a semiconductor fabrication
facility, these manufacturers will tend to choose semiconductor equipment
manufacturers based on established relationships, product compatibility, and
proven financial performance.

Once a semiconductor manufacturer selects a particular vendor's capital
equipment, the manufacturer generally relies for a significant period of time
upon equipment from this "vendor of choice" for the specific production line
application. In addition, the semiconductor manufacturer frequently will attempt
to consolidate its other capital equipment requirements with the same vendor.
Accordingly, we may face narrow windows of opportunity to be selected as the
"vendor of choice" by substantial new customers. It may be difficult for us to
sell to a particular customer for a significant period of time once that
customer selects a competitor's product, and we may not be successful in
obtaining broader acceptance of our systems and technology. If we are unable to
achieve broader market acceptance of our systems and technology, we may be
unable to grow our business and our operating results and financial condition
will be adversely affected.


Unless We Can Continue To Develop and Introduce New Systems that Compete
Effectively on the Basis of Price and Performance, We May Lose Future Sales and
Customers, Our Business May Suffer, and Our Stock Price May Decline.

Because of continual changes in the markets in which our customers and we
compete, our future success will depend in part upon our ability to continue to
improve our systems and technologies. These markets are characterized by rapidly
changing technology, evolving industry standards, and continuous improvements in
products and services. Due to the continual changes in these markets, our
success will also depend upon our ability to develop new technologies and
systems that compete effectively on the basis of price and performance and that
adequately address customer requirements. In addition, we must adapt our systems
and processes to support emerging target market industry standards.

The success of any new systems we introduce is dependent on a number of
factors, including timely completion of new system designs accepted by the
market, and may be adversely affected by manufacturing inefficiencies and the
challenge of producing systems in volume which meet customer requirements. We
may not be able to improve our existing systems or develop new technologies or
systems in a timely manner. In particular, the transition of the market to 300
mm wafers will present us with both an opportunity and a risk. To the extent
that we are unable to introduce 300mm systems that meet customer requirements on
a timely basis, our business could be harmed. We may exceed the budgeted cost of
reaching our research, development and engineering objectives, and estimated
product development schedules may require extension. Any delays or additional
development costs could have a material adverse effect on our business and
results of operations. Because of the complexity of our systems, significant
delays can occur between the introduction of systems or system enhancements and
the commencement of commercial shipments.


35


The Timing of the Transition to 300mm Technology is Uncertain and Competition
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 timing of the industry's transition to 300mm manufacturing
technology is uncertain, partly as a result of the recent period of reduced
demand for semiconductors. Delay in the transition to 300mm manufacturing
technology could adversely affect our potential revenues and opportunities for
future growth. Moreover, delay in the transition to 300mm technology could
permit our competitors to introduce competing or superior 300mm products at more
competitive prices, causing competition to become more vigorous.


Delays or Technical and Manufacturing Difficulties Incurred in the Introduction
of New Products Could Be Costly and Adversely Affect Our Customer Relationships.

From time to time, we have experienced delays in the introduction of, and
certain technical and manufacturing difficulties with, certain systems and
enhancements, and may experience such delays and technical and manufacturing
difficulties in future introductions or volume production of new systems or
enhancements. For example, our inability to overcome such difficulties, to meet
the technical specifications of any new systems or enhancements, or to
manufacture and ship these systems or enhancements in volume and in a timely
manner, would materially adversely affect our business and results of
operations, as well as our customer relationships. In addition, we may from time
to time incur unanticipated costs to ensure the functionality and reliability of
our products early in their life cycles, which costs can be substantial. If new
products or enhancements experience reliability or quality problems, we could
encounter a number of difficulties, including reduced orders, higher
manufacturing costs, delays in collection of accounts receivable, and additional
service and warranty expenses, all of which could materially adversely affect
our business and results of operations.


We May Not Be Able To Continue To Successfully Compete in the Highly Competitive
Semiconductor Industry.

The semiconductor equipment industry is both highly competitive and
subject to rapid technological change. Significant competitive factors include
the following:

o system performance;

o cost of ownership;

o size of installed base;

o breadth of product line; and

o customer support.

The following characteristics of our major competitors' systems may give
them a competitive advantage over us:

o broader product lines;

o longer operating history;

o greater experience with high volume manufacturing;

o broader name recognition;

o substantially larger customer bases; and

o substantially greater financial, technical, and marketing resources.

In addition, to expand our sales we must often replace the systems of our
competitors or sell new systems to customers of our competitors. Our competitors
may develop new or enhanced competitive products that will offer price or
performance features that are superior to our systems. Our competitors may also
be able to respond more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the development,
promotion, and sale of their product lines. We may not be able to maintain or
expand our sales if competition increases and we are unable to respond
effectively.


36


We Depend Upon a Limited Number of Suppliers for Some Components and
Subassemblies, and Supply Shortages or the Loss of These Suppliers Could Result
In Increased Cost or Delays in Manufacture and Sale of Our Products.

We rely to a substantial extent on outside vendors to manufacture many of
the components and subassemblies of our systems. We obtain some of these
components and subassemblies from a sole source or a limited group of suppliers.
Because of our anticipated reliance on outside vendors generally, and on a sole
or a limited group of suppliers in particular, we may be unable to obtain an
adequate supply of required components. Although we currently experience minimal
delays in receiving goods from our suppliers, when demand for semiconductor
equipment is strong, as it was in 2000, our suppliers strained to provide
components on a timely basis.

In addition, during periods of shortages of components, we may have
reduced control over pricing and timely delivery of components. We often quote
prices to our customers and accept customer orders for our products prior to
purchasing components and subassemblies from our suppliers. If our suppliers
increase the cost of components or subassemblies, we may not have alternative
sources of supply and may no longer be able to increase the cost of the system
being evaluated by our customers to cover all or part of the increased cost of
components.

The manufacture of some of these components and subassemblies is an
extremely complex process and requires long lead times. As a result, we have in
the past and we may in the future experience delays or shortages. If we are
unable to obtain adequate and timely deliveries of our required components or
subassemblies, we may have to seek alternative sources of supply or manufacture
such components internally. This could delay our ability to manufacture or
timely ship our systems, causing us to lose sales, incur additional costs, delay
new product introductions, and harm our reputation.


We Are Highly Dependent on Our Key Personnel to Manage Our Business and Their
Knowledge of Our Business, Management Skills, and Technical Expertise Would Be
Difficult to Replace.

Our success will depend to a large extent upon the efforts and abilities
of our executive officers, our current management and our technical staff, any
of whom would be difficult to replace. Several of our executive officers have
recently joined us or have assumed new responsibilities at the company. The
addition, reassignment or loss of key employees could limit or delay our ability
to develop new products and adapt existing products to our customers' evolving
requirements and result in lost sales and diversion of management resources.


Because of Competition for Additional Qualified Personnel, We May Not Be Able To
Recruit or Retain Necessary Personnel, Which Could Impede Development or Sales
of Our Products.

Our growth will depend on our ability to attract and retain qualified,
experienced employees. There is substantial competition for experienced
engineering, technical, financial, sales, and marketing personnel in our
industry. In particular, we must attract and retain highly skilled design and
process engineers. Historically, competition for such personnel has been intense
in all of our locations, but particularly in the San Francisco Bay Area where
our headquarters is located. If we are unable to retain existing key personnel,
or attract and retain additional qualified personnel, we may from time to time
experience inadequate levels of staffing to develop and market our products and
perform services for our customers. As a result, our growth could be limited due
to our lack of capacity to develop and market our products to our customers, or
we could fail to meet our delivery commitments or experience deterioration in
service levels or decreased customer satisfaction.

If the current downturn ends suddenly, we may not have enough personnel to
promptly return to our previous production levels. If we are unable to expand
our existing manufacturing capacity to meet demand, a customer's placement of a
large order for our products during a particular period might deter other
customers from placing similar orders with us for the same period. It could be
difficult for us to rapidly recruit and train substantial numbers of qualified
technical personnel to meet increased demand.


37



If We Are Unable to Protect Our Intellectual Property, We May Lose a Valuable
Asset, Experience Reduced Market Share, and Efforts to Protect Our Intellectual
Property May Require Additional Costly Litigation.

We rely on a combination of patents, copyrights, trademark and trade
secret laws, non-disclosure agreements, and other intellectual property
protection methods to protect our proprietary technology. Despite our efforts to
protect our intellectual property, our competitors may be able to legitimately
ascertain the non-patented proprietary technology embedded in our systems. If
this occurs, we may not be able to prevent the use of such technology. Our means
of protecting our proprietary rights may not be adequate and our patents may not
be sufficiently broad to protect our technology. In addition, any patents owned
by us could be challenged, invalidated, or circumvented and any rights granted
under any patent may not provide adequate protection to us. Furthermore, we may
not have sufficient resources to protect our rights. Our competitors may
independently develop similar technology, duplicate our products, or design
around patents that may be issued to us. In addition, the laws of some foreign
countries may not protect our proprietary rights to as great an extent as do the
laws of the United States and it may be more difficult to monitor the use of our
products in such foreign countries. As a result of these threats to our
proprietary technology, we may have to resort to costly litigation to enforce
our intellectual property rights.

We are currently litigating several matters involving our wet division
intellectual property. These legal proceedings, whether with or without merit,
could be time-consuming and expensive to prosecute or defend, and could divert
management's attention and resources. There can be no assurance as to the
outcome of current or future legal proceedings or claims. Defenses or
counterclaims in these proceedings could result in the nullification of any or
all of the subject patents.


We Might Face Intellectual Property Infringement Claims that May Be Costly to
Resolve and Could Divert Management Attention Including the Potential for Patent
Infringement Litigation as a Result of Our Increased Market Strength in RTP and
Entry into the Wet Processing Market.

We may from time to time be subject to claims of infringement of other
parties' proprietary rights. Competitors alleging infringement of such
competitors' patents have in the past sued our acquired company, STEAG
Semiconductor Division. Although all such historic lawsuits have been settled or
terminated, the risk of further intellectual property litigation for us may be
increased following the expansion of our business after the merger.

Our involvement in any patent dispute or other intellectual property
dispute or action to protect trade secrets, even if the claims are without
merit, could be very expensive to defend and could divert the attention of our
management. Adverse determinations in any litigation could subject us to
significant liabilities to third parties, require us to seek costly licenses
from third parties, and prevent us from manufacturing and selling our products.
Royalty or license agreements, if required, may not be available on terms
acceptable to us or at all. Any of these situations could have a material
adverse effect on our business and operating results in one or more countries.


Our Failure to Comply with Environmental Regulations Could Result
in Substantial Liability.

We are subject to a variety of federal, state, local, and foreign laws,
rules, and regulations relating to environmental protection. These laws, rules,
and regulations govern the use, storage, discharge, and disposal of hazardous
chemicals during manufacturing, research and development and sales
demonstrations. If we fail to comply with present or future regulations, we
could be subject to substantial liability for clean up efforts, personal injury,
and fines or suspension or cessation of our operations. We may be subject to
liability if our acquired companies have past violations. Restrictions on our
ability to expand or continue to operate our present locations could be imposed
upon us or we could be required to acquire costly remediation equipment or incur
other significant expenses.


38


The Effect of Terrorist Threats on the General Economy Could Decrease Our
Revenues.

On September 11, 2001, the United States was subject to terrorist attacks
at the World Trade Center buildings in New York City and the Pentagon in
Washington D.C. The potential near- and long-term impact these attacks may have
in regards to our suppliers and customers, markets for their products and the
U.S. economy are uncertain. There may be other potential adverse effects on our
operating results due to this significant event that we cannot foresee.


Future Sales of Shares by STEAG Could Adversely Affect the Market Price of Our
Common Stock.

There are approximately 37.0 million shares of our common stock
outstanding as of December 31, 2001, of which approximately 11.8 million (or
32%) are held beneficially by STEAG. STEAG has agreed to restrictions on its
ability to acquire additional shares of our stock, other than to maintain its
percentage ownership in us, and from soliciting proxies and certain other
standstill restrictions in connection with voting shares of our common stock,
for a period of five years after its acquisition of the stock. STEAG may sell
these shares in the public markets from time to time, subject to certain
limitations on the timing, amount and method of such sales imposed by SEC
regulations, and STEAG has the right to require us to register for resale all or
a portion of the shares they hold. If STEAG were to sell a large number of
shares, the market price of our common stock could decline. Moreover, the
perception in the public markets that such sales by STEAG might occur could also
adversely affect the market price of our common stock.


The Price of Our Common Stock Has Fluctuated in the Past and May Continue to
Fluctuate Significantly in the Future, Which May Lead to Losses By Investors or
to Securities Litigation.

The market price of our common stock has been highly volatile in the past,
and our stock price may decline in the future. We believe that a number of
factors could cause the price of our common stock to fluctuate, perhaps
substantially, including:

o general conditions in the semiconductor industry or in the worldwide
economy;

o announcements of developments related to our business;

o fluctuations in our operating results and order levels;

o announcements of technological innovations by us or by our
competitors;

o new products or product enhancements by us or by our competitors;

o developments in patent litigation or other intellectual property
rights; or

o developments in our relationships with our customers, distributors,
and suppliers.

In addition, in recent years the stock market in general, and the market
for shares of high technology stocks in particular, have experienced extreme
price fluctuations. These fluctuations have frequently been unrelated to the
operating performance of the affected companies. Such fluctuations could
adversely affect the market price of our common stock. In the past, securities
class action litigation has often been instituted against a company following
periods of volatility in its stock price. This type of litigation, if filed
against us, could result in substantial costs and divert our management's
attention and resources.


Any Future Business Acquisitions May Disrupt Our Business, Dilute
Stockholder Value, or Distract Management Attention.

As part of our ongoing business strategy, we may consider additional
acquisitions of, or significant investments in, businesses that offer products,
services, and technologies complementary to our own. Such acquisitions could
materially adversely affect our operating results and/or the price of our common
stock. Acquisitions also entail numerous risks, including:


39


o difficulty of assimilating the operations, products, and personnel of
the acquired businesses;

o potential disruption of our ongoing business;

o unanticipated costs associated with the acquisition;

o inability of management to manage the financial and strategic position
of acquired or developed products, services, and technologies;

o inability to maintain uniform standards, controls, policies, and
procedures; and

o impairment of relationships with employees and customers that may
occur as a result of integration of the acquired business.

To the extent that shares of our stock or other rights to purchase stock
are issued in connection with any future acquisitions, dilution to our existing
stockholders will result and our earnings per share may suffer. Any future
acquisitions may not generate additional revenue or provide any benefit to our
business, and we may not achieve a satisfactory return on our investment in any
acquired businesses.



ITEM 7A: QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk.

Our exposure to market risk for changes in interest rates relates to our
investment portfolio. We do not use derivative financial instruments in our
investment portfolio. We place our investments with high credit quality issuers
and, by policy, limit the amount of credit exposure to any one issuer. The
portfolio includes only marketable securities with active secondary or resale
markets to ensure portfolio liquidity. We have no cash flow exposure due to rate
changes for cash equivalents and short-term investments, as all of these
investments are at fixed interest rates.

Foreign Currency Risk

We transact business in various foreign countries. During 2000, we employed a
foreign currency hedging program utilizing foreign currency forward exchange
contracts to hedge foreign currency fluctuations with Japan. The goal of the
hedging program is to lock in exchange rates to minimize the impact to us of
foreign currency fluctuations. We do not use foreign currency forward exchange
contracts for speculative or trading purposes.

The following table provides information as of December 31, 2001 about our
derivative financial instruments, which are comprised of foreign currency
forward exchange contracts. The information is provided in U.S. dollar
equivalent amounts. The table presents the notional amounts (at the contract
exchange rates), the weighted average contractual foreign currency exchange
rates, and the estimated fair value of those contracts.

The local currency is the functional currency for all foreign sales
operations. Our exposure to foreign currency risk has increased as a result of
our global expansion of business. In addition, a payment obligation to STEAG AG
in the amount estimated to be $17.1 million is payable in EUROS and,
accordingly, there exists exposure for exchange rate volatility. The exposure
for the exchange rate volatility of the STEAG payment obligation has been mostly
neutralized by using a natural balance sheet hedge and keeping EUROS in a
foreign currency bank account. The balance of this bank account was 17.1 million
EUROS at December 31, 2001.

MATTSON TECHNOLOGY, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Mattson Technology, Inc. (the "Company" or "Mattson") was incorporated in
California on November 18, 1988. In September 1997, the Company was
reincorporated in the State of Delaware. As part of the reincorporation, each
outstanding share of the California corporation, no par value common stock, was
converted automatically to one share of the new Delaware corporation, $0.001 par
value common stock.

The Company designs, manufactures and markets semiconductor wafer processing
equipment used in "front-end" fabrication of integrated circuits to the
semiconductor manufacturing industry worldwide.

Risks and Uncertainties

Based on current projections, the Company believes that its current cash and
investment positions together with cash provided by operations will be
sufficient to meet its anticipated cash needs for working capital and capital
expenditures for at least the next twelve months. The Company's operating plans
are based on and require that the Company reduce its operating losses, control
expenses, manage inventories, and collect accounts receivable balances. In the
current semiconductor market downturn, the Company is exposed to a number of
challenges and risks, including delays in payments of accounts receivable by
customers, and postponements or cancellations of orders. Postponed or cancelled
orders can cause excess inventory and underutilized manufacturing capacity. If
the Company is not able to significantly reduce its present operating losses
over the upcoming quarters, the operating losses could adversely affect cash and
working capital balances, and the Company may be required to seek additional
sources of financing.

The Company may need to raise additional funds in future periods through
public or private financing, or other sources, to fund operations. The Company
may not be able to obtain adequate or favorable financing when needed. Failure
to raise capital when needed could harm the business. If additional funds are
raised through the issuance of equity securities, the percentage ownership of
the stockholders would be reduced, and these equity securities may have rights,
preferences or privileges senior to the common stock. Any additional equity
financing may be dilutive to stockholders, and debt financing, if available, may
involve restrictive covenants on the Company's operations and financial
condition.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and
its subsidiaries. All significant intercompany accounts and transactions have
been eliminated in consolidation.

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
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 revenue and expenses during
the reported periods. Actual results could differ from those estimates.

The Company's fiscal year ends on December 31. The Company's fiscal quarters
end on the last Sunday in the calendar quarter.

Revenue Recognition

Mattson derives revenue from two primary sources - equipment sales and
spare part sales. In December 1999, the Securities and Exchange Commission
issued Staff Accounting Bulletin No. 101 (SAB 101), "Revenue Recognition in
Financial Statements." The Company implemented the provisions of SAB 101 in the
fourth quarter of 2000, retroactive to January 1, 2000. The Company previously
recognized revenue from the sales of its products generally at the time of
shipment of the product. Effective January 1, 2000, the Company changed its




47



method of accounting for equipment sales and on equipment sales (a) of existing
products where the arrangement includes new specifications, (b) where the sale
is to a new customer and includes acceptance clauses, (c) on all sales of new
products, or (d) on all sales of wet surface preparation products, revenue is
recognized on customer acceptance. For equipment sales to existing customers of
products of a type previously sold to such customer, under an arrangement that
includes customer specified acceptance provisions that Mattson has previously
demonstrated, the lesser of the fair value of the equipment or the contractual
amount billable upon shipment is recorded as revenue upon transfer of title,
which usually occurs upon delivery of the product. Revenue not recognized at the
time of shipment is recorded as deferred revenue and recognized as revenue upon
customer acceptance. From time to time, however, the Company allows customers to
evaluate systems, and since customers can return evaluation systems at any time
with limited or no penalty, the Company does not recognize revenues on these
products until the evaluation systems are accepted by the customer. Revenues
related to direct sales in Japan are recognized upon customer acceptance.
Thermal products sold through a distributor in Japan are recognized upon
transfer of title to the distributor. Equipment that has been delivered to
customers but has not been accepted is classified as "Inventories - delivered
systems" in the accompanying consolidated balance sheets. Receivables for which
revenue has not been recognized are classified as "Advance Billings" in the
accompanying consolidated balance sheets. Deferred revenue was $136.6 million as
of December 31, 2001 and $40.7 million as of December 31, 2000. These amounts
represent equipment that was shipped for which amounts were billed per the
contractual terms but have not been recognized as revenue in accordance with SAB
101.

Revenue recognition for spare part sales has not changed under the provisions
of SAB 101 and is recognized upon shipment of the spare parts. In all cases,
revenue is only recognized when persuasive evidence of an arrangement exists,
delivery has occurred, the price is fixed and determinable and collectibility is
reasonably assured.

As a result of the change in recognition of revenue on equipment sales,
Mattson reported a change in accounting principle in accordance with Accounting
Principles Board ("APB") Opinion No. 20 "Accounting Changes", by a cumulative
adjustment. The cumulative effect of the change in accounting principle of
($8.1) million (or $.38 per diluted share) was reported as a charge in the
quarter ended March 31, 2000. The charge includes system revenue, net of cost of
sales and certain expenses, including warranty and commission expenses that will
be recognized when the conditions for revenue recognition are met.

Service and maintenance contract revenue, which to date has been
insignificant, is recognized on a straight-line basis over the service period of
the related contract.


Cash and Cash Equivalents

The Company considers all highly liquid instruments with an original
maturity of three months or less to be cash equivalents. Cash equivalents
consist primarily of money market funds.

Restricted Cash

At December 31, 2001, the Company had $27.3 million of restricted cash
invested in certificates of deposit. This restricted cash collateralizes the
$26.9 million secured promissory note issued to STEAG Electronic Systems AG, in
connection with the January 1, 2001 acquisition of certain subsidiaries of STEAG
Electronic Systems AG (see Note 2), and additionally collateralizes $0.4 million
of the Company's corporate credit card.

Investments

Investments primarily consist of commercial paper and U.S. Treasury
securities. The Company classifies its investments in commercial paper and U.S.
Treasury securities as available-for-sale. The investments are reported at fair
market value, in accordance with the provisions of Statements of Financial
Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." As of December 31, 2001, the fair value of the
investments in commercial paper and U.S. Treasury securities approximated
amortized cost and, as such, unrealized holding gains and losses were not
significant. The fair value of the Company's investments was determined based on
the quoted market prices at the reporting date for those instruments.
Investments with a contractual maturity of one year or less are classified as
short-term in the accompanying consolidated balance sheets. At December 31, 2001
and 2000, the Company had $0 and $9.3 million, respectively, in long-term
investments. Realized gain on the sale of investments are included in the
accompanying consolidated statements of operations.

48


Inventories

Inventories are stated at the lower of cost or market, with cost determined
on a first-in, first-out basis and include material, labor and
manufacturing overhead costs.

The Company regularly monitors inventory quantities on hand and obsolete
inventories that are no longer used in current production. Based on the current
estimated requirements, it was determined that there was excess and obsolete
inventory and those excess and obsolete amounts were fully reserved as of
December 31, 2001 and 2000. Due to competitive pressures and the cyclicality of
the semiconductor industry, it is possible that these estimates could change in
the near term.


Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using
the straight-line method based upon the estimated useful lives of the assets,
which range from three to five years. Leasehold improvements are amortized using
the straight-line method over the term of the related lease or the estimated
useful lives of the improvements, whichever is shorter. Depreciation expense was
$16.6 million, $4.2 million, and $3.8 million for the years ended December 31,
2001, 2000 and 1999, respectively. When assets are retired or otherwise disposed
of, the assets and related accumulated depreciation are removed from the
accounts. Gains or losses resulting from retirements or disposals are included
in other income in the accompanying consolidated statements of operations.
Repair and maintenance costs are expensed as incurred.


Goodwill and Intangibles

Goodwill and intangibles represent the purchase price of the semiconductor
equipment division of STEAG Electronic Systems, CFM Technologies, Inc., and
Concept Systems Design in excess of identified tangible assets (see Note 2). In
connection with the merger, effective January 1, 2001, the Company recorded
$207.3 million of goodwill and intangible assets which were being amortized on a
straight-line basis over three to seven years. Intangible assets are comprised
of purchased technology and workforce and are presented at cost, net of
accumulated amortization. Amortization expense was $33.5 million, $0.9 million
and $1.0 million for the years ended December 31, 2001, 2000 and 1999,
respectively. Upon adoption of SFAS 142 on January 1, 2002, the Company will no
longer amortize goodwill, thereby eliminating annual goodwill amortization of
approximately $3.9 million, based on anticipated amortization for 2002. The
Company will continue to amortize the identified intangibles, with an estimated
$6.7 million in amortization expense in 2002.

Impairment of Long-Lived Assets

Mattson reviews long-lived assets and identifiable intangible assets for
impairment whenever events or changes in circumstances indicate that the
carrying amount of these assets may not be recoverable. Mattson assesses these
assets for impairment based on estimated undiscounted future cash flows from
these assets for the operating entities that had separately identifiable future
cash flow. If the carrying value of the assets exceeds the estimated future
undiscounted cash flows, a loss is recorded as the excess of the asset's
carrying value over the fair value. Long-lived assets to be disposed of are
reported at the lower of carrying amount or fair value less costs to sell.
During 2001, in connection with its acquisitions of the STEAG Semiconductor
Division and CFM, Mattson recorded an impairment loss of $145.4 million to
reduce goodwill, intangible assets, and property and equipment based on the
amount by which the carrying value of the assets exceeded their fair value as
determined based on estimated discounted future cash flows (see Note 2).


Warranty

The warranty offered by the Company on its systems ranges from 12 months to
36 months depending on the product. A provision for the estimated cost of
warranty is recorded as a cost of sales when the revenue is recognized.

49



Stock-Based Compensation

In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock-Based Compensation." As allowed by the provisions of
SFAS No. 123, the Company has continued to apply APB Opinion No. 25 in
accounting for its stock option plans and, accordingly, does not recognize
compensation cost because the exercise price equals the market price of the
underlying stock at the date of grant. The Company has adopted the disclosure
provisions of SFAS No. 123 and Note 6 to the Consolidated Financial Statements
contains a summary of the pro forma effects to reported net income (loss) and
earnings (loss) per share for the years ended December 31, 2001, 2000 and 1999
for compensation cost based on the fair value of the options granted at the
grant date as prescribed by SFAS No. 123. In April 2000, the Financial
Accounting Standards Board issued FIN 44, "Accounting for Certain Transactions
Involving Stock Compensation: An Interpretation of APB No. 25." The Company has
adopted the provisions of FIN 44 and such adoption did not materially impact the
Company's result of operations.

Foreign Currency Accounting

The local currency is the functional currency for all foreign operations.
Accordingly, all assets and liabilities of these foreign operations are
translated using exchange rates in effect at the end of the period, and revenues
and costs are translated using average exchange rates for the period. Gains or
losses from translation of foreign operations where the local currencies are the
functional currency are included as a component of accumulated other
comprehensive income/(loss). Foreign currency transaction gains and losses are
recognized in the consolidated statements of operations as they are incurred and
have not been material.

Forward Foreign Exchange Contracts

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS 133, as
amended by SFAS 138, establishes accounting and reporting standards requiring
that all derivatives that are hedged be recorded in the balance sheet as either
an asset or liability measured at its fair value. The statement requires that
changes in the derivative's fair value be recognized currently in earnings
unless specific hedge criteria are met. Gains or losses are reported either in
the statement of operations or as a component of comprehensive income, depending
on the type of hedging relationship that exists. The Company adopted the
standard in the first quarter of 2001. The impact of the adoption has not been
significant to the Company's results of operations.

The Company uses forward foreign exchange contracts primarily to hedge the
short-term impact of foreign currency fluctuations of intercompany accounts
payable denominated in U.S. dollars recorded by its Japanese subsidiary. All
forward foreign exchange contracts employed by the Company are short-term in
nature. Because the impact of movements in currency exchange rates on forward
foreign exchange contracts offsets the related impact on the underlying items
being hedged, these financial instruments do not subject the Company to
speculative risks that would otherwise result from changes in currency exchange
rates. All foreign currency contracts are marked-to-market and realized and
unrealized gains and losses on hedged forward foreign exchange contracts are
deferred and recognized in the accompanying consolidated statements of
operations when the related transactions being hedged are recognized. Gain and
losses on unhedged foreign currency transactions are recognized as incurred. To
date, premiums paid for forward exchange contracts have not been material and
there are no significant losses as of December 31, 2001 for open contracts.

Comprehensive Income

In 1998, the Company adopted SFAS No. 130, "Reporting Comprehensive Income."
SFAS No. 130 establishes standards for disclosure and financial statement
presentation for reporting total comprehensive income and its individual
components. Comprehensive income, as defined, includes all changes in equity
during a period from non-owner sources. The Company's comprehensive income
includes net loss, foreign currency translation adjustments, increase in minimum
pension liability, derivative gains and losses and unrealized gains and losses
on investments and is presented in the statement of stockholders' equity.


50



Net Income (Loss) Per Share

Basic earnings per share is computed by dividing net income (loss) by the
weighted average number of common shares outstanding during the period. Diluted
earnings per share gives effect to all dilutive potential common shares
outstanding during the period. For purposes of computing diluted earnings per
share, weighted average common share equivalents do not include stock options
with an exercise price that exceeded the average market price of the Company's
common stock for the period.

Income Taxes

The Company provides for income taxes under the provisions of SFAS No. 109
"Accounting for Income Taxes." SFAS No. 109 requires an asset and liability
based approach in accounting for income taxes. Deferred income tax assets and
liabilities are recorded based on the differences between the financial
statement and tax bases of assets and liabilities using enacted tax rates.
Valuation allowances are provided against assets which are not likely to be
realized.

Segment Reporting

In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information." SFAS No. 131 establishes standards on
reporting information about operating segments in annual financial statements
and also requires companies to report selected segment information in interim
financial reports. The Company operates in one reportable segment. Note 11 of
the Consolidated Financial Statements contains a summary table of industry
segment, geographic and customer information.

New Accounting Pronouncements

On June 29, 2001, the Financial Accounting Standard Board (FASB) approved
for issuance SFAS No. 141, "Business Combinations", and SFAS No. 142, "Goodwill
and Other Intangible Assets". Major provisions of these Statements are as
follows: all business combinations initiated after June 30, 2001 must use the
purchase method of accounting; the pooling of interest methods of accounting is
prohibited except for transactions initiated before July 1, 2001; intangible
assets acquired in a business combination must be recorded separately from
goodwill if they arise from contractual or other legal rights or are separable
from the acquired entity and can be sold, transferred, licensed, rented or
exchanged, either individually or as part of a related contract, asset or
liability; goodwill and intangible assets with indefinite lives are not
amortized but are tested for impairment annually using a fair value approach,
except in certain circumstances, and whenever there is an impairment indicator;
other intangible assets will continue to be valued and amortized over their
estimated lives; in-process research and development will continue to be written
off immediately; all acquired goodwill must be assigned to reporting units for
purposes of impairment testing and segment reporting; effective January 1, 2002,
existing goodwill and certain intangible assets will no longer be subject to
amortization; goodwill arising between July 1, 2001 and December 31, 2001 will
not be subject to amortization.

Upon adoption of SFAS No. 142, on January 1, 2002, the Company no longer
amortizes goodwill and certain intangible assets, thereby eliminating annual
goodwill amortization of approximately $3.9 million, based on anticipated
amortization for 2002. The Company will continue to amortize the identified
intangibles. The amortization expense is estimated to be $6.7 million for 2002.
Amortization of goodwill and intangibles for the year ended December 31, 2001
was approximately $33.5 million including amounts related to the amortization of
goodwill and intangibles of CFM and the STEAG Semiconductor Division, which
became impaired (Note 2).

In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations," ("SFAS 143"). SFAS 143 addresses accounting and
reporting for obligations associated with the retirement of tangible long-lived
assets and the associated asset retirement costs. This Statement requires that
the fair value of a liability for an asset retirement obligation be recognized
in the period in which it is incurred if a reasonable estimate of fair value can
be made. The associated asset retirement costs are capitalized as part of the
carrying amount of the long-lived asset. The liability is accreted to its
present value each period while the cost is depreciated over its useful life.
SFAS 143 is effective for financial statements issued for fiscal years beginning
after June 15, 2002. The Company believes that the adoption of SFAS 143 will not
have a significant effect on its financial position, results of operations or
cash flows.


51



In October 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets," ("SFAS 144"). SFAS 144, which
replaces SFAS 121 "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of," requires long-lived assets to be measured
at the lower of carrying amount or fair value less the cost to sell. SFAS 144
also broadens disposal transactions reporting related to discontinued
operations. SFAS 144 is effective for financial statements issued for fiscal
years beginning after December 15, 2001. The Company believes that the adoption
of SFAS 144 will not have a significant effect on its financial position,
results of operations or cash flows.

Reclassifications

Certain amounts in prior years have been reclassified to conform with the
current year presentation.


2. ACQUISITIONS

On June 27, 2000, the Company entered into a definitive Strategic Business
Combination Agreement, subsequently amended by an Amendment to the Strategic
Business Combination Agreement dated December 15, 2000 ("Combination
Agreement"), as amended on November 5, 2001, to acquire eleven direct and
indirect subsidiaries, comprising the semiconductor equipment division of STEAG
Electronic Systems AG ("the STEAG Semiconductor Division"), and entered into an
Agreement and Plan of Merger ("Plan of Merger") to acquire CFM Technologies,
Inc. ("CFM"). Both transactions were completed simultaneously on January 1,
2001.

STEAG Semiconductor Division

Pursuant to the Combination Agreement, the Company issued to STEAG Electronic
Systems AG ("SES") 11,850,000 shares of common stock valued at approximately
$124 million as of the date of the amended Combination Agreement, paid SES
$100,000 in cash, and assumed certain obligations of SES and STEAG AG, the
parent company of SES, including certain intercompany indebtedness owed by the
acquired subsidiaries to SES, in exchange for a secured promissory note in the
principal amount of $26.9 million (with an interest rate of 6%). Under the
Combination Agreement, the Company is also obligated to pay to SES the amount of
19.2 million EUROS (approximately $17.1 million as of December 31, 2001). Under
both of these obligations, the Company owes an aggregate amount of approximately
$44.6 million to SES, including accrued interest at 6% per annum, which was
originally payable on July 2, 2001. The Company and SES reached an agreement to
extend the terms of the amounts due until July 2, 2002.

The Company reimbursed SES $3.3 million in acquisition related costs, in
April 2001. The Company also agreed to grant options to purchase 850,000 shares
of common stock to employees of the STEAG Semiconductor Division subsequent to
the closing of the transaction, which is not included in the purchase price of
the STEAG Semiconductor Division. As part of the acquisition transaction, the
Company, SES, and Mr. Mattson (the then chief executive officer and
approximately 17.7% stockholder of the Company, based on shares outstanding
immediately prior to the acquisition) entered into a Stockholder Agreement dated
December 15, 2000, as amended on November 5, 2001, providing for, among other
things, the election of two persons designated by SES to the Company's board of
directors, SES rights to maintain its pro rata share of the outstanding Company
common stock and participate in future stock issuances by the Company, and
registration rights in favor of SES. The Company also entered into several
transition services agreements with SES, under which SES agreed to provide
specified payroll, communications, accounting information and intellectual
property administration services to certain German subsidiaries of the Company
for a term of one year. In fiscal year 2001, the Company paid SES approximately
$988,000 in connection with the purchase of services and supplies pursuant to
the transition services agreements. In addition, the Company entered into a
manufacturing supply contract with a company affiliated with SES, under which
the Company had the right to utilize manufacturing and assembly services based
on an hourly rate. For fiscal 2001, the Company purchased $3.7 million worth of
such manufacturing and assembly services. At December 31, 2001, SES held
approximately 32% of the Company's common stock, and currently has two
representatives on the Company's board of directors.


52


The acquisition has been accounted for under the purchase method of
accounting and the results of operations of the STEAG Semiconductor Division are
included in the consolidated statement of operations of the Company from the
date of acquisition. The purchase price of the acquisition of $148.6 million,
which included $6.2 million of direct acquisition related costs (including the
amount reimbursed to SES), was used to acquire the common stock of the eleven
direct and indirect subsidiaries of the STEAG Semiconductor Division. The
allocation of the purchase price to the assets acquired and liabilities assumed,
is as follows (in thousands):

Net tangible assets ........................ $ 114,513
Acquired developed technology .............. 18,100
Acquired workforce ......................... 11,500
Goodwill ................................... 10,291
Acquired in-process research and development 5,400
Deferred tax liability ..................... (11,248)
---------
$ 148,556
=========

Purchased intangible assets, including goodwill, workforce and developed
technology of approximately $39.9 million, are being amortized over their
estimated useful lives of seven, three and five years, respectively. The Company
attributed $5.4 million to in-process research and development which was
expensed immediately.

In connection with the acquisition of the STEAG Semiconductor Division, the
Company allocated approximately $5.4 million of the purchase price to in-process
research and development projects. This allocation represented the estimated
fair value based on risk-adjusted cash flows related to the incomplete research
and development projects. At the date of acquisition, the development of these
projects had not yet reached technological feasibility, and the research and
development in progress had no alternative future uses. Accordingly, the
purchase price allocated to in-process research and development was expensed as
of the acquisition date.

At the acquisition date, the STEAG Semiconductor Division was conducting
design, development, engineering and testing activities associated with the
completion of the Hybrid tool and the Single wafer tool. The projects under
development at the valuation date represent next-generation technologies that
are expected to address emerging market demands for wet processing equipment.

At the acquisition date, the technologies under development were
approximately 60 percent complete based on engineering man-month data and
technological progress. The STEAG Semiconductor Division had spent approximately
$3.3 million on the in-process projects, and expected to spend approximately an
additional $2.4 million to complete all phases of the R&D. Anticipated
completion dates ranged from 10 to 18 months, at which times the Company
expected to begin benefiting from the developed technologies.

In making its purchase price allocation, management considered present value
calculations of income, an analysis of project accomplishments and remaining
outstanding items, an assessment of overall contributions, as well as project
risks. The value assigned to purchased in-process technology was determined by
estimating the costs to develop the acquired technology into commercially viable
products, estimating the resulting net cash flows from the projects, and
discounting the net cash flows to their present value. The revenue projection
used to value the in-process research and development was based on estimates of
relevant market sizes and growth factors, expected trends in technology, and the
nature and expected timing of new product introductions by the Company and its
competitors. The resulting net cash flows from such projects are based on
management's estimates of cost of sales, operating expenses, and income taxes
from such projects.

Aggregate revenues for the developmental STEAG Semiconductor Division
products were estimated to grow at a compounded annual growth rate of
approximately 41 percent for the seven years following introduction, assuming
the successful completion and market acceptance of the major R&D programs. The
estimated revenues for the in-process projects were expected to peak within five
years of acquisition and then decline sharply as other new products and
technologies were expected to enter the market.

The rates utilized to discount the net cash flows to their present value were
based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the projected growth and profitability of
the developmental projects, a discount rate of 23 percent was used to value the
in-process R&D. This discount rate was commensurate with the STEAG Semiconductor
Division stage of development and the uncertainties in the economic estimates
described above.




53


If these projects are not successfully developed, the sales and
profitability of the combined company may be adversely affected in future
periods. Additionally, the value of other acquired intangible assets may become
impaired.

During the third and fourth quarters of 2001, the Company performed
assessments of the carrying value of its long-lived assets to be held and used
including goodwill, other intangible assets and property and equipment recorded
in connection with its acquisition of the STEAG Semiconductor Division. The
assessment was performed pursuant to SFAS No. 121 as a result of deteriorated
market conditions in the semiconductor industry in general, a reduced demand
specifically for the Thermal products acquired in the merger and revised
projected cash flows for these products in the future. As a result of this
assessment, the Company recorded a charge of $3.5 million in the third quarter
of 2001 to reduce the carrying value of certain intangible assets associated
with the acquisition of the STEAG Semiconductor Division based on the amount by
which the carrying value of these assets exceeded their fair value. Fair value
was determined based on valuations performed by an independent third party. In
addition, the Company recorded a charge of $1.0 million in the third quarter of
2001 to reduce certain property and equipment purchased from the STEAG
Semiconductor Division to zero as there are no future cash flows expected from
these assets. No impairment charges were required in the fourth quarter of 2001.
The charge of $4.5 million relating to the STEAG Semiconductor Division has been
recorded as impairment of long-lived assets and other charges in the
accompanying consolidated statements of operations.

CFM Technologies

Under the Plan of Merger with CFM, the Company agreed to acquire CFM in a
stock-for-stock merger in which the Company issued 0.5223 shares of its common
stock for each share of CFM common stock outstanding at the closing date. In
addition, the Company agreed to assume all outstanding CFM stock options, based
on the same 0.5223 exchange ratio. The Company also agreed to issue additional
options to purchase 500,000 shares of its common stock to employees of CFM
subsequent to the closing of the transaction. On January 1, 2001, the Company
completed its acquisition of CFM. The purchase price included 4,234,335 shares
of Mattson common stock valued at approximately $150.2 million and the issuance
of 927,457 options to acquire Mattson common stock for the assumption of
outstanding options to purchase CFM common stock valued at approximately $20.4
million using the Black Scholes option pricing model and the following
assumptions: risk free interest rate of 6.5%, average expected life of 2 years,
dividend yield of 0% and volatility of 80%.

The merger has been accounted for under the purchase method of accounting
and the results of operations of CFM are included in the consolidated statement
of operations of the Company from the date of acquisition. The purchase price of
the acquisition of CFM was $174.6 million, which included $4.0 million of direct
acquisition related costs. The allocation of the purchase price to the assets
acquired and liabilities assumed, is as follows (in thousands):

Net tangible assets ............................. $ 28,536
Acquired developed technology ................... 50,500
Acquired workforce ............................. 14,700
Goodwill ........................................ 102,216
Acquired in-process research and development .... 4,700
Deferred tax liability .......................... (26,081)
--------
$174,571
========

Purchased intangible assets, including goodwill, workforce and developed
technology of approximately $167.4 million are being amortized over their
initial estimated useful lives of seven, three and five years, respectively. The
Company attributed $4.7 million to in-process research and development which was
expensed immediately.

In connection with the acquisition of CFM, the Company allocated
approximately $4.7 million of the purchase price to an in-process research and
development project. This allocation represented the estimated fair value based
on risk-adjusted cash flows related to one incomplete research and development
project. At the date of acquisition, the development of this project had not yet
reached technological feasibility, and the research and development in progress
had no alternative future use. Accordingly, the purchase price allocated to
in-process research and development was expensed as of the acquisition date.

54


At the acquisition date, CFM was conducting design, development, engineering
and testing activities associated with the completion of the O3Di (Ozonated
Water Module). The project under development at the valuation date represents
next-generation technology that is expected to address emerging market demands
for more effective, lower cost, and safer resist and oxide removal processes. At
the acquisition date, the technology under development was approximately 80
percent complete based on engineering man-month data and technological progress.
CFM had spent approximately $0.2 million on the in-process project, and expected
to spend approximately an additional $50,000 to complete all phases of the
research and development. Anticipated completion dates ranged from 2 to 3
months, at which times the Company expected to begin benefiting from the
developed technology.

In making its purchase price allocation, management considered present value
calculations of income, an analysis of project accomplishments and remaining
outstanding items, an assessment of overall contributions, as well as project
risks. The value assigned to purchased in-process research and development was
determined by estimating the costs to develop the acquired technology into a
commercially viable product, estimating the resulting net cash flows from the
project, and discounting the net cash flows to their present value. The revenue
projection used to value the in-process research and development was based on
estimates of relevant market sizes and growth factors, expected trends in
technology, and the nature and expected timing of new product introductions by
the Company and its competitors. The resulting net cash flows from the project
is based on management's estimates of cost of sales, operating expenses, and
income taxes from such projects.

Aggregate revenues for the developmental CFM product were estimated for the
five to seven years following introduction, assuming the successful completion
and market acceptance of the major research and development programs. The
estimated revenues for the in-process project was expected to peak within two
years of acquisition and then decline sharply as other new products and
technologies are expected to enter the market.

The rates utilized to discount the net cash flows to their present value were
based on estimated cost of capital calculations. Due to the nature of the
forecast and the risks associated with the projected growth and profitability of
the developmental project, a discount rate of 23 percent was used to value the
in-process research and development. This discount rate was commensurate with
CFM's stage of development and the uncertainties in the economic estimates
described above.

If this project is not successfully developed, the sales and profitability of
the combined company may be adversely affected in future periods. Additionally,
the value of other acquired intangible assets may become impaired.

During the third and fourth quarters of 2001, the Company performed
assessments of the carrying value of the long-lived assets to be held and used
including goodwill, other intangible assets and property and equipment recorded
in connection with its acquisition of CFM. The assessment was performed pursuant
to SFAS No. 121 as a result of deteriorated market conditions in the
semiconductor industry in general, a reduced demand specifically for the Omni
products acquired in the merger and revised projected cash flows for these
products in the future. As a result of this assessment, the Company recorded a
charge of $134.6 million during 2001 to reduce the carrying value of goodwill,
and other intangible assets, associated with the acquisition of CFM based on the
amount by which the carrying value of these assets exceeded their fair value.
Fair value was determined based on valuations performed by an independent third
party. In addition, the Company recorded a charge of $5.8 million to reduce
certain property and equipment purchased from CFM to zero as there are no future
cash flows expected from these assets. The total charge of $140.4 million
relating to CFM has been recorded as impairment of long-lived assets and other
charges in the accompanying statements of operations.

The following table presents the unaudited pro forma results for the year
ended December 31, 2000 assuming that the Company acquired the STEAG
Semiconductor Division and CFM on January 1, 2000. The pro forma information
does not purport to be indicative of what would have occurred had the
acquisitions been made as of January 1, 2000 or of the results that may occur in
the future. Net loss excludes the write-off of acquired-in-process research and
development of $10.1 million and includes amortization of goodwill and
intangibles related to these acquisitions of $33.5 million for the year ended
December 31, 2000. The unaudited pro forma information is as follows (in
thousands, except net loss per share):

3. DEBT

As discussed in Note 2, the Company has notes payable to STEAG Electronic
Systems AG in the aggregate amount of $44.6 million. The note accrue interest at
6% per annum and are due July 2, 2002. The notes contains certain covenants
including maintaining a minimum accounts receivable balance of $15.9 million. At
December 31, 2001, the Company was in compliance with the covenants.

During fiscal 2000, one of the subsidiaries that the Company acquired as
part of the STEAG Semiconductor Division entered into a two-year revolving line
of credit with a bank in Japan in the amount of 500 million Yen (approximately
$3.8 million), with a term expiring September 2002. Under this line of credit,
the borrowing was 450 million Yen (approximately $3.5 million) which was paid
back in full in December 2001, and thereafter the Company cancelled the line of
credit. The line of credit bore interest at a rate of 1.96% per annum through
March 2001 and thereafter bore interest at a rate of 1.75% per annum. The line
of credit was secured by a letter of credit in the amount of $5.1 million and
required the pledge of restricted cash in the same amount, which upon the
payment of the line of credit in December 2001 was converted into unrestricted
cash.

Additionally, one of Mattson's Japanese subsidiaries entered into a credit
line with a bank in Japan in the amount of 900 million Yen (approximately $6.9
million) secured by trade accounts receivable. The line bears interest at a per
annum rate of TIBOR plus 75 basis points (0.81% at December 31, 2001). The term
of the line was through December 28, 2001 but was extended through June 20,
2002. The credit line is guaranteed by the Company. At December 31, 2001, 601.7
million Yen (approximately $4.6 million) was outstanding on this line of credit.

Long-term debt is comprised of a $809,418 mortgage payable and various
capital lease obligations.

The carrying amount of the outstanding debt obligations at December 31, 2001
approximated fair value due to the short maturities of these obligations.



4. SEVERANCE CHARGE

In fiscal 2001, the Company recorded a charge of $8.1 million for severance.
The charge is included in selling, general, and administrative expense and is
related to the termination of 466 employees. During the year, $2.6 million was
paid for severance and at December 31, 2001 the remaining severance accrual was
$5.5 million.

covers inventories for Thermal and Omni products that were acquired in the
merger with the Steag Semiconductor Division and CFM. As of December 31, 2001
and 2000, the allowance for excess and obsolete inventory was approximately
$48.0 million and $6.8 million respectively. In addition, during 2001, the
Company recorded impairment charges for long-lived assets of $144.9 million (see
Note 2).

6. CAPITAL STOCK

Mattson's authorized capital stock consists of 120,000,000 shares of common
stock of which 37,032,100 were issued and outstanding at December 31, 2001 and
2,000,000 shares of preferred stock, none of which were outstanding at December
31, 2001.

Common Stock

On March 8, 2000 the Company completed its secondary public offering of
3,000,000 shares of its common stock. The public offering price was $42.50 per
share. On March 16, 2000, the underwriters exercised a right to purchase an
additional 90,000 shares to cover over-allotments. The net proceeds of the
offering were $122.8 million.

Stock Option Plan

In September 1989, the Company adopted an incentive and non-statutory stock
option plan under which a total of 9,675,000 shares of common stock have been
reserved for issuance. Options granted under this Plan are for periods not to
exceed ten years. Incentive stock option and non-statutory stock option grants
under the Plan must be at prices at least 100% and 85%, respectively, of the
fair market value of the stock on the date of grant. The options generally vest
25% one year from the date of grant, with the remaining vesting 1/36th per month
thereafter.

A summary of the status of the Company's stock option plans at December 31,
2001, 2000 and 1999 and changes during the years then ended is presented in the

Compensation cost under SFAS No. 123 for the fair value of each incentive
stock option grant is estimated on the date of grant using the Black-Scholes
option-pricing model for the multiple option approach with the following
weighted average assumptions:

Employee Stock Purchase Plan

In August 1994, the Company adopted an employee stock purchase plan
("Purchase Plan") under which 2,975,000 shares of common stock have been
reserved for issuance. The Purchase Plan is administered generally over offering
periods of 24 months, with each offering period divided into four consecutive
six-month purchase periods beginning May 1 and November 1 of each year. Eligible
employees may designate not more than 15% of their cash compensation to be
deducted each pay period for the purchase of common stock under the Purchase
Plan and participants may not purchase more than $25,000 worth of common stock
in any calendar year or 10,000 shares in any offering period. On the last
business day of each purchase period, shares of common stock are purchased with
the employees' payroll deductions accumulated during the six months, at a price
per share equal to 85% of the market price of the common stock on the date
immediately preceding the offering date or the date immediately preceding the
purchase date, whichever is lower.

The weighted average fair value on the grant date of rights granted under the
employee stock purchase plan was approximately $5.92 in 2001, $3.15 in 2000, and
$3.15 in 1999.

Compensation cost under SFAS No. 123 is calculated for the estimated fair
value of the employees' stock purchase rights using the Black-Scholes
option-pricing model with the following average assumptions:

Pro Forma Effect of Stock-Based Compensation Plans

In accordance with the provisions of SFAS No. 123, the Company applies APB
Opinion No. 25 in accounting for its incentive stock option and employee stock
purchase plans, and accordingly, does not recognize compensation cost in the
statement of operations because the exercise price of the stock options equals
the market price of the underlying stock on the date of grant. If the Company
had elected to recognize compensation cost based on the fair value of the
options granted at grant date as prescribed by SFAS No. 123, net income (loss)
and income (loss) per share would have been adjusted to the pro forma amounts
indicated in the table below:

Year Ended December 31,
----------------------------------------
2001 2000 1999
---- ---- ----
(in thousands, except per share amounts)

Net income (loss):
As reported $(336,735) $ 1,539 $ (849)
Pro forma $(347,324) $(1,991) $(5,430)
Diluted net income (loss) per share:
As reported $ (9.14) $ 0.07 $ (0.05)
Pro forma $ (9.42) $ (0.09) $ (0.35)



As the SFAS No. 123 method of accounting has not been applied to options
granted prior to July 1995, the resulting pro forma compensation cost may not be
representative of that to be expected in future years.


7. INCOME TAXES

follows:

--------- --------- ---------
Total provision for income taxes $ (18,990) $ 1,068 $ 247
========= ========= =========


The valuation allowance at December 31, 2001 and 2000 is attributable to
federal and state deferred tax assets. Management believes that sufficient
uncertainty exists with regard to the realizability of tax assets such that a
valuation allowance is necessary. Factors considered in providing a valuation
allowance include the lack of a significant history of consistent profits and
the lack of carryback capacity to realize these assets. Based on the absence of
objective evidence, management is unable to assert that it is more likely than
not that the Company will generate sufficient taxable income to realize all the
Company's net deferred tax assets. At December 31, 2001, the Company had Federal
net operating loss carryforwards of approximately $146 million which will
expire at various dates through 2021. Approximately $44 million of the
deferred tax asset was acquired by Mattson from STEAG, CFM and Concept and, if
realized, will be used to reduce the amount of goodwill and intangibles recorded
at the date of acquisition. The federal and state net operating losses acquired
from STEAG, CFM and Concept are also subject to change in control limitations.
If certain substantial changes in the Company's ownership occur, there would be
an additional annual limitation on the amount of the net operating loss
carryforwards which can be utilized. Approximately $987,000 of the valuation
allowance is related to stock option deductions which, if realized, will be
accounted for as an addition to equity rather than as a reduction of the
provision for taxes.

8. EMPLOYEE BENEFIT PLANS

The Company has a retirement/savings plan (the "Plan"), which is qualified under
section 401(k) of the Internal Revenue Code. All full-time employees who are
twenty-one years of age or older are eligible to participate in the Plan. The
Plan allows participants to contribute up to 20% of the total compensation that
would otherwise be paid to the participant, not to exceed the amount allowed by
the applicable Internal Revenue Service guidelines. The Company may make a
discretionary matching contribution equal to a percentage of the participant's
contributions. In 2001, 2000, and 1999 the Company made matching contributions
of $1,171,000, $663,000, $226,000, respectively.

One of the acquired STEAG entities has a pension plan that is established in
accordance with certain German laws. Benefits are determined based upon
retirement age and years of service with the Company. The plan is not funded and
there are no plan assets. The Company makes payments to the plan when
distributions to participants are required. The accumulated benefit obligation
acquired under the pension plan on January 1, 2001 (date of acquisition) was
$640,000. Pension expense for the year was $32,000. At December 31, 2001, the
accumulated benefit obligation was $636,000.


9. NET INCOME (LOSS) PER SHARE

Earnings per share is calculated in accordance with SFAS No. 128, "Earnings
Per Share." SFAS No. 128 requires dual presentation of basic and diluted net
income (loss) per share on the face of the income statement. Basic earnings per
share is computed by dividing income (loss) available to common stockholders by
the weighted average number of common shares outstanding for the period. Diluted
EPS gives effect to all dilutive potential common shares outstanding during the
period. The computation of diluted EPS uses the average market prices during the
period. All amounts in the following table are in thousands except per share
data.




Year Ended December 31,
-----------------------------------------
2001 2000 1999

December 31, 2000 of 480,637, and at December 31, 1999 of 3,143,000 were
excluded from the computations of diluted net income (loss) per share because of
their anti-dilutive effect on earnings (loss) per share.

10. RELATED PARTY TRANSACTIONS

The Company purchases certain inventory parts from a supplier company, R.F.
Services. In April 2001, the Company completed the acquisition of 97% of the
outstanding shares of R.F. Services, Inc. for a cash price of approximately
$928,800 (including acquisition-related costs of $41,500). Brad Mattson, a
member of the Company's board of directors and the Company's former Chief
Executive Officer, owned a majority of the outstanding shares of R.F. Services,
Inc. and served as a director of that corporation. Net purchases prior to the
acquisition in 2001 were $868,000, and net purchases during 2000 and 1999 were
$1,161,000 and $680,000, respectively.

During the second quarter of 2000, the Company extended a loan to Mr. Mattson
in the principal amount of $200,000. The interest rate of the loan is 6% per
annum. As of March 15, 2002, Mr. Mattson owed the Company a total of $221,867
pursuant to the loan. The repayment of the loan was originally due in the first
quarter of 2001, but the Company extended the maturity date to December 31,
2002.

During the fourth quarter of 1998, the Company extended a two-year loan to
David Dutton, the Company's current Chief Executive Officer and former
President, Plasma Product Division, in the principal amount of $100,000. The
loan is collateralized by approximately 32,000 shares of the Company's common
stock and is a full recourse note bearing interest at 6% per annum. During the
second quarter of 2000, the Company extended a second loan to Mr. Dutton in the
principal amount of $50,000. The interest rate on the second loan is 6% per
annum. The repayment of the second loan was originally due in the first quarter
of 2001. During the third quarter of 2001, the Company extended a note to Mr.
Dutton in the amount of $20,000. The interest rate on the third loan is 6% per
annum, and is due on December 31, 2002. As of December 31, 2001 and 2000, the
total principal balance owed on these loans were $170,000 and $150,000,
respectively. The Company has extended the maturity date on the first two loans
to December 31, 2002.

During the third quarter of 2000, the Company extended a loan to Mr. Morita,
Executive Vice President, Global Business Operations, in the principal amount of
$300,000. The interest rate of the loan is 6% per annum. As of December 31, 2001
and 2000, principal balance owed on the loan was $300,000. The repayment of the
loan was originally due in the first quarter of 2001, but the Company extended
the maturity date to December 31, 2002.

At December 31, 2001, we had loans receivable from other employees of $1.9
million. The interest rates on these loans range from 5.5% to 6%. The loans are
due in 2002.

The Company entered into a consulting agreement with Shigeru Nakayama, a
member of its Board of Directors, on August 10, 2000. Under his consulting
agreement, Mr. Nakayama receives $10,000 per month and an option to purchase
6,000 shares of Company common stock per year, in exchange for consulting
services regarding the integration of the Company's operations in Japan. In May
2001, the Company made payments of $90,000 to Mr. Nakayama for consulting
services performed from August 2000 to April 2001.

STEAG Electronic Systems AG ("SES") holds approximately 32% of the Company's
common stock, which it obtained in conjunction with the Company's acquisition of
eleven subsidiaries of SES (see Note 2). Pursuant to the Stockholder Agreement
entered into in connection with the acquisition transaction, Dr. Jochen Melchior
and Dr. Hans-Georg Betz were elected to the Company's Board of Directors as
designees of SES.

On November 5, 2001, the Company and SES amended the Combination Agreement
and the Stockholder Agreement. The Amendment to the Stockholder Agreement
eliminated the restrictions on future dispositions of Company common stock by
SES. The Second Amendment to the Combination Agreement provided for, among other
things, the amendment of the secured promissory note issued to SES in connection
with the acquisition transaction, extending the maturity date and capitalizing
accrued interest, and the issuance of a second secured promissory note in lieu
of payment of profits of two of the acquired subsidiaries due to SES, as
required under the Combination Agreement. As discussed in Note 2 and 3, the
Company owed SES $44.6 million at December 31, 2001.


63



In fiscal year 2001, the Company paid approximately $988,000 to SES in
connection with the purchase of services or supplies pursuant to several
transitional services agreements with SES, under which SES agreed to provide
specified payroll, communications, accounting information and intellectual
property administration services to certain German subsidiaries of the Company.
In addition, in fiscal 2001, the Company purchased approximately $3.7 million of
manufacturing and assembly services pursuant to a manufacturing supply contract
with a company affiliated with SES.

The Company paid Alliant Partners, a technology merger and acquisition
advisory firm, a fee of $300,000 for rendering an opinion as to the fairness
from a financial point of view to Mattson's stockholders of the consideration to
be provided by Mattson in connection with the acquisition of the STEAG
Semiconductor Division and CFM. The Company also agreed to pay Alliant Partners
a success fee of $2,000,000 upon the closing of the transactions. This payment
was made in January 2001. This amount was capitalized in 2000 as a direct
acquisition related cost. Mr. Savage, who was a member of Mattson's Board of
Director until January 1, 2001 is a partner at Alliant Partners.


11. REPORTABLE SEGMENTS

SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information" establishes standards for reporting information about operating
segments, geographic areas and major customers in financial statements.
Operating segments are defined as components of an enterprise about which
separate financial information is available that is evaluated regularly by the
chief operating decision maker, or chief decision making group, in deciding how
to allocate resources and in assessing performance. The Chief Executive Officer
of the Company is the Company's chief decision maker. As the Company's business
is completely focused on one industry segment, the design, manufacturing and
marketing of advanced fabrication equipment to the semiconductor manufacturing
industry, management believes that the Company has one reportable segment. The
Company's revenues and profits are generated through the sale and service of
products for this one segment.

The following is net sales information by geographic area for the years ended
December 31 (in thousands):

2001 2000 1999
-------- -------- --------
United States $ 51,148 $ 56,736 $ 30,428
Japan 34,190 8,118 10,706
Taiwan 29,394 53,355 20,173
Korea 17,418 23,029 22,081
Singapore 11,487 13,470 8,441
Europe 71,224 25,922 11,629
China 15,243 -- --
Other Asian countries 45 -- --
-------- -------- --------
$230,149 $180,630 $103,458
======== ======== ========

The net sales above have been allocated to the geographic areas based upon
the installation location of the systems.

For purposes of determining sales to significant customers, the Company
includes sales to customers through its distributor (at the sales price to the
distributor) and excludes the distributor as a significant customer. In 2001,
13% of net sales were to a single customer. In 2000, no single customer
accounted for greater than 10% of net sales. In 1999, 20% of net sales was to
a single customer.

64



12. CONCENTRATION OF CREDIT RISK

Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash equivalents,
investments, trade accounts receivable and financial instruments used in hedging
activities.

The Company invests in a variety of financial instruments such as
certificates of deposit, corporate bonds and treasury bills. The Company limits
the amount of credit exposure to any one financial institution or commercial
issuer. To date, the Company has not experienced significant losses on these
investments.

The Company's trade accounts receivable are concentrated with companies in
the semiconductor industry and are derived from sales in the United States,
Japan, other Pacific Rim countries and Europe. The Company performs ongoing
credit evaluations of its customers and records specific allowances for bad
debts when a customer is unable to meet its financial obligation as in the case
of bankruptcy filings or deteriorated financial position. Estimates are used in
determining allowances for all other customers based on factors such as current
trends, the length of time the receivables are past due and historical
collection experience. During the year ended December 31, 2001, the Company
provided approximately $6.9 million to increase its allowance for doubtful
accounts receivable to a level deemed necessary by management to provide for
potential uncollectible accounts.

The Company is exposed to credit loss in the event of non performance by
counterparties on the forward foreign exchange contracts used in hedging
activities. The Company does not anticipate nonperformance by these
counterparties.


13. COMMITMENTS AND CONTINGENCIES

The Company leases 29 out of its 31 facilities under operating leases, which
expire at various dates through 2019, with minimum annual rental commitments as
follows (in thousands):


2002....................................................... $9,507
2003....................................................... 6,375
2004....................................................... 3,759
2005....................................................... 3,285
2006....................................................... 2,932
Thereafter................................................. 19,953
-------
$45,811
=======


Rent expense was approximately $10.7 million in 2001, $3.9 million in 2000,
and $1.9 million in 1999. The increase in rent expense in 2001 was due to the
inclusion of the facilities leased by the companies acquired by the Company on
January 1, 2001.

During the year ended December 31, 2001, the semiconductor industry was in
a significant and prolonged downturn, and the Company experienced lower
bookings, significant push outs and cancellation of orders as a result of these
unfavorable economic conditions. Accordingly, given the Company's acquisition of
additional facilities resulting from the acquisitions of STEAG Semiconductor
Division and CFM, the Company performed a comprehensive analysis of its real
estate facility requirements and identified excess facility buildings, which
have been offered for sublease and sale. The Company, at its Exton, Pennsylvania
location, leases two buildings to house its manufacturing and administrative
functions related to the Omni product. The two buildings have leases of 17 years
remaining on them with an approximate combined rental cost of $1.5 million
annually. The leases for these two buildings allow for subleasing the premises
without the approval of the landlord. In addition, the Company has excess
facilities in San Jose, CA, and has non-cancelable annual lease payments of
approximately $1 million over one year related to this facility. Factors
considered in the analysis included, but were not limited to, anticipated future
revenue growth rates and anticipated future headcount and manufacturing
requirements. Based upon the results of this analysis and the excess facilities
space identified, during the six months ended December 31, 2001, the Company
recorded a charge of $3.2 million related to facilities lease losses as
impairment of long-lived assets and other charges in the accompanying


65




consolidated statement of operations. As of December 3, 2001, there is a lease
loss accrual of $3.2 million recorded as accrued liabilities in the accompanying
consolidated balance sheet. In determining the facilities lease loss, net of
cost recovery efforts from expected sublease income, various assumptions were
made, including, the time period over which the building will be vacant;
expected sublease terms; and expected sublease rates. The facilities lease
losses and related asset impairment charges are estimates in accordance with
SFAS No. 5, "Accounting for Contingencies," and represent the low-end of an
estimated range that may be adjusted upon the occurrence of future triggering
events. Triggering events may include, but are not limited to, changes in
estimated time to sublease, sublease terms, and sublease rates. Should operating
lease rental rates continue to decline in current markets or should it take
longer than expected to find a suitable tenant to sublease the facilities,
adjustments to the facilities lease losses accrual will be made in future
periods, if necessary, based upon the then current actual events and
circumstances. The Company has estimated that under certain circumstances the
facilities lease losses could increase approximately $1.5 million for each
additional year that the facilities remain un-leased and could aggregate $25.5
million under certain circumstances.

The Company expects to make payments related to the above noted facilities
lease losses over the next seventeen years.

As of December 31, 2001, the Company has established an accrual for purchase
commitments of $1.3 million for excess inventory component commitments to key
component vendors that it believes may not be realizable during future normal
ongoing operations. No such accrual was required at December 31, 2000.

The Company is party to certain claims arising in the ordinary course of
business. While the outcome of these matters is not presently determinable,
management believes that they will not have a material adverse effect on the
financial position or results of operations of the Company.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders of Mattson Technology, Inc.:

We have audited the accompanying consolidated balance sheets of Mattson
Technology, Inc. (a Delaware corporation) and subsidiaries as of December 31,
2001 and 2000 and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 2001. These financial statements and the schedule referred to
below are the responsibility of the Company's management. Our responsibility is
to express an opinion on these financial statements and schedule based on our
audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards 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. An audit also includes assessing the accounting principles used and
the significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Mattson Technology, Inc. and
subsidiaries as of December 31, 2001 and 2000, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 2001 in conformity with accounting principles generally accepted in
the United States of America.

Our audits were made for the purpose of forming an opinion on the basic
consolidated financial statements taken as a whole. The schedule listed in the
index to consolidated financial statements is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not part of
the basic consolidated financial statements. This schedule has been subjected to
the auditing procedures applied in the audits of the basic consolidated
financial statements and, in our opinion, fairly states in all material respects
the financial data required to be set forth therein in relation to the basic
consolidated financial statements taken as a whole.

Voting Arrangements

In connection with the business combination in which we acquired the

entered into a Stockholder Agreement with SES and Brad Mattson that provides,
among other things, for the appointment of two persons designated by SES to join
our board of directors. Dr. Jochen Melchior and Dr. Hans Georg-Betz were
designated by SES and were appointed as directors effective January 1, 2001. The
Stockholder Agreement also provides that we will cause the nomination of Dr.
Melchior and Dr. Betz, or successors designated by SES, for election at each
annual meeting of our stockholders at which their terms as directors will
expire. SES and Mr. Mattson each agreed to be present and voting at each

for the election of nominees for director proposed in accordance with the
Stockholder Agreement.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our officers
and directors, and persons who own more than ten percent of a registered class
of our equity securities, to file reports of ownership and changes in ownership
with the Securities and Exchange Commission. Officers, directors and greater
than ten-percent shareholders are required by SEC regulations to furnish us with
copies of all Section 16(a) forms they file.

To our knowledge, based solely on review of the copies of such reports
furnished to us and written representation from certain reporting persons that
no other reports were required, we believe that all Section 16(a) filing
requirements applicable to our executive officers, directors and greater than
ten percent shareholders were complied with.

- ---------
(1) Options granted in fiscal year 2001 to executive officers were granted
under our 1989 Stock Option Plan, have ten-year terms and, except as set
forth below, vest over a period of four years at a rate of 25% after one
year and 1/48th each month thereafter, conditioned upon continous
employment with us. Under the 1989 Stock Option Plan, the Board of
Directors retains discretion to modify the terms, including the price of
outstanding options.

(2) We granted an aggregate of 3,298,556 options during the fiscal year ended
December 31, 2001.

(3) All options were granted at fair market value on the date of grant,
representing the closing sale price of our common stock as quoted on the
Nasdaq National Market on the date of grant.

(4) The options in this table may terminate before their expiration upon the
termination of the optionee's status as an employee or consultant or upon
the optionee's disability or death.


72




(5) Potential gains are net of exercise price, but before taxes associated
with exercise. These amounts represent certain assumed rates of
appreciation only, in accordance with the Securities and Exchange
Commission's rules. Actual gains, if any, on stock option exercises are
dependent on the future performance of the common stock, overall market
conditions and the option holders' continued employment through the
vesting period. The 5% and 10% assumed annual rates of appreciation are
specified in SEC rules and do not represent our estimate or projection of
future stock price growth. We do not necessarily agree that this method
can properly determine the value of an option and there can be no
assurance that the potential realizable values shown in this table will be
achieved. One share of stock purchased at $7.65 in fiscal 2001 would yield
profits of approximately $4.81 per share at 5% appreciation over ten
years, or approximately $12.19 per share at 10% appreciation over the same
period. One share of stock purchased at $10.44 in fiscal 2001 would yield
profits of approximately $6.57 per share at 5% appreciation over ten
years, or approximately $16.64 per share at 10% appreciation over the same
period. One share of stock purchased at $13.36 in fiscal 2001 would yield
profits of approximately $8.40 per share at 5% appreciation over ten
years, or approximately $21.29 per share at 10% appreciation over the same
period. One share of stock purchased at $15.03 in fiscal 2001 would yield
profits of approximately $9.45 per share at 5% appreciation over ten
years, or approximately $23.95 per share at 10% appreciation over the same
period.

(1) Represents shares which are immediately exercisable and/or vested. Options
granted in fiscal 2001 under the 1989 Stock Option Plan generally vest and
become exercisable over a period of four years at a rate of 25% after one
year and 1/48th each month thereafter. Under the 1989 Stock Option Plan, the
Board of Directors retains discretion to modify the terms, including the
price of outstanding options.

(2) Represents shares which are unvested and not exercisable.

(3) Market value of underlying securities is based on the closing price of our
Common Stock on December 31, 2001 (the last trading day of the 2001 fiscal
year), which was $8.81 as reported on the Nasdaq National Market.

(4) Represents shares that are immediately exercisable and/or vested.


73


Shares Acquired on Exercise includes all shares underlying the option, or
portion of the option, exercised without deducting shares withheld to satisfy
tax obligations, sold to pay the exercise price or otherwise disposed of. Value
Realized is calculated by multiplying the difference between the market value,
deemed to be the closing market price of our common stock on the Nasdaq National
Market, and exercise price when exercised by the number of shares acquired upon
exercise. The value of any payment by the Company for the exercise price or
related taxes is not included. Value of Unexercised In-the-Money Options at
Fiscal Year End is calculated by multiplying the difference between the market
value and exercise price at fiscal year end by the number of options held at
fiscal year end.

Compensation of Directors

Non-employee directors are paid $5,000 per Board of Directors meeting
attended, with no cap on the number of meetings. The Chairman is paid $10,000

out-of-pocket expenses associated with attending meetings. Non-employee
directors are paid $1,000 or, in the case of the Chairman, $2,000 per committee

Currently, each non-employee director is granted options to purchase 30,000
shares on the date of appointment or election to the Board, and each is to be
granted an option to purchase an additional 10,000 shares or, the case of the
Chairman, an option to purchase an additional 15,000 shares in, each year
thereafter, on the date immediately after each annual meeting of stockholders
following which he remains a non-employee director of the Company, as long as he
has continuously served on the board for six months as of the date of the annual
meeting of stockholders.

Employment Contracts and Termination of Employment and
Change-in-Control Arrangements

None of our current executive officers have employment agreements with us,
and they may resign and their employment may be terminated at any time.

Effective as of October 15, 2001, Brad Mattson resigned as our chief

Directors, unless requested to resign by a majority of the board for good cause,
and that during the term of the Transition Agreement Mr. Mattson will vote his
shares of our Common Stock in the manner recommended by a majority of the Board
of Directors, provided that he shall have no obligation to vote for any proposal
that adversely impacts his rights as a stockholder in a manner materially
adverse to the impact on other stockholders. In addition, Mr. Mattson agrees
that, during the term of the Transition Agreement, he will not compete with our
business.

Pursuant to our Amended and Restated 1989 Stock Option Plan, in the event

to the date of the change in control. Any option or portion thereof that is
neither assumed or substituted for by the acquiring corporation nor exercised as
of the date of the change in control will terminate and cease to be outstanding
effective as of the date of the change in control.

Pursuant to our 1994 Employee Stock Purchase Plan, as amended, in the event
of a proposed sale of all or substantially all of our assets, or a merger or
consolidation, then in the sole discretion of the plan administrator, (1) each
option granted under the 1994 Plan shall be assumed or an equivalent option
shall be substituted by the successor corporation, (2) all outstanding options
shall be deemed exercisable on a date set by the administrator that is on or
before the date of consummation of such merger, consolidation or sale or (3) all

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

In April 2001, we completed the acquisitions of 97% of the outstanding
shares of R.F. Services, Inc. for a cash price of approximately $928,800
(including acquisition-related costs of $41,500). Brad Mattson, a member of our
board of directors and our former Chief Executive Officer, owned a majority of
the outstanding shares of R.F. Services, Inc. and served as a director of that
corporation.

During the second quarter of 2000, we extended a loan to Mr. Mattson in
the principal amount of $200,000. The interest rate of the loan is 6%. As of
March 15, 2002, Mr. Mattson owed us a total of $221,867 pursuant to the loan.
The repayment of the loan was originally due in the first quarter of 2001, but
the Company extended the maturity date to December 31, 2002.

During the fourth quarter of 1998, we extended a two-year loan to David
Dutton, our current Chief Executive Officer and former President, Plasma Product
Division, in the principal amount of $100,000. The loan is collateralized by
approximately 32,000 shares of our common stock and is a full recourse note
bearing interest at 6% per year. During the second quarter of 2000, we extended
a second loan to Mr. Dutton in the principal amount of $50,000. The interest
rate on the second loan is 6%. The repayment of the second loan was originally
due in the first quarter of 2001. During the third quarter of 2001, we extended
a third loan to Mr. Dutton in the amount of $20,000. The interest rate on these
loans is 6%. As of March 15, 2002, Mr. Dutton owed us a total of $204,070
pursuant to the loans. The maturity date on the loans is December 31, 2002.

During the third quarter of 2000, we extended a loan to Mr. Morita in the
principal amount of $300,000. The interest rate on the loan is 6%. As of March
15, 2002, Mr. Morita owed us a total of $327,700 pursuant to the loan. The
repayment of the loan was originally due in the first quarter of 2001, but we
extended the maturity date to December 31, 2002.

We entered into a consulting agreement with Shigeru Nakayama, a member of
our Board of Directors, on August 10, 2000. Under his consulting agreement, Mr.
Nakayama receives $10,000 per month and an option to purchase 6,000 shares of
our Common Stock per year, in exchange for consulting services regarding the
integration of our operations in Japan. In May 2001, we made payments of $90,000
to Mr. Nakayama for consulting services performed from August 2000 to April
2001.

STEAG Electronic Systems AG ("SES") holds approximately 32% of our Common
Stock, which it acquired pursuant to the purchase by us of eleven subsidiaries
of SES, which was consummated on January 1, 2001 under the terms of a Strategic
Business Combination Agreement by and between SES and us, dated June 27, 2000,
as amended by the Amendment to Strategic Business Combination Agreement dated
December 15, 2000 (the "Combination Agreement"). Pursuant to the Stockholder
Agreement entered into in connection with the acquisition transaction, Dr.
Jochen Melchior and Dr. Hans-Georg Betz were elected to our Board of Directors
as designees of SES.

On November 5, 2001, we agreed with SES to amend the Combination Agreement
and the Stockholder Agreement. The Amendment to Stockholder Agreement eliminated
the restrictions on future dispositions of our Common Stock by SES. The Second
Amendment to the Combination Agreement provided for, among other things, the
amendment of the secured promissory note issued to SES in connection with the
acquisition transaction, extending the maturity date and capitalizing accrued
interest, and an additional loan from SES to us in an amount equal to the year
2000 profits that were transferred from two of the acquired German subsidiaries
to SES pursuant to the Combination Agreement. We issued the Amended and Restated
Secured Promissory Note in the principal amount of $26.9 million with an
interest rate of 6% per annum. This note is secured by a standby letter of
credit, which is in turn secured by restricted cash in the principal amount of
the note. We also issued to SES the second Secured Promissory Note in the
principal amount of approximately Euro 19.2 million, with an interest rate of 6%
per annum and secured by an assignment of accounts receivable of the two
acquired German subsidiaries. Both notes are due on July 2, 2002.

In fiscal year 2001, we paid approximately $988,000 to SES in connection
with the purchase of services or supplies pursuant to several transition
services agreements with SES, under which SES agreed to provide specified
payroll, communications, accounting information and intellectual property
administration services to certain of our German subsidiaries. In addition, in
fiscal 2001, the Company purchased approximately $3.7 million of manufacturing
and assembly services pursuant to a manufacturing supply contract with a company
affiliated with SES.


77



Effective as of October 15, 2001, Brad Mattson resigned as our chief
executive officer. Pursuant to the Transition Agreement by and between Mr.
Mattson and us, dated as of December 13, 2001, Mr. Mattson shall continue to
work for us as a part time employee, assisting on strategic issues, for a term
of two years from the date of his resignation. Mr. Mattson shall be paid
$450,000 per year for his services. The Transition Agreement also provides that,
among other things, Mr. Mattson will continue to serve on our Board of
Directors, unless requested to resign by a majority of the board for good cause,
and that during the term of the Transition Agreement Mr. Mattson will vote his
shares of our Common Stock in the manner recommended by a majority of the Board
of Directors, provided that he shall have no obligation to vote for any proposal
that adversely impacts his rights as a stockholder in a manner materially
adverse to the impact on other stockholders. In addition, Mr. Mattson agrees
that, during the term of the Transition Agreement, he will not compete with our
business.

The Company paid Alliant Partners, a technology merger and acquisition
advisory firm, a fee of $300,000 for rendering an opinion as to the fairness
from a financial point of view to Mattson's stockholders of the consideration to
be provided by Mattson in connection with the acquisition of the STEAG
Semiconductor Division and CFM. The Company also agreed to pay Alliant Partners
a success fee of $2,000,000 upon the closing of the transactions. This payment
was made in January 2001. This amount was capitalized in 2000 as a direct
acquisition related cost. Mr. Savage, who was a member of Mattson's Board of
Director until January 1, 2001 is a partner at Alliant Partners.
