ITEM 1.  BUSINESS

GENERAL

     LSI Logic Corporation (together with its subsidiaries collectively referred
to as LSI Logic or the Company and referred to as we, us and our) is a leader in
the design, development, manufacture, and marketing of complex, high-performance
integrated circuits and storage systems. We are focused on the four markets of
consumer products, communications, storage components, and storage area network
systems. Our integrated circuits are used in a wide range of communication
devices, including devices used for wireless, broadband, data networking, and
set-top box applications. We also provide other types of integrated circuit
products and board-level products for use in consumer applications,
high-performance storage controllers, and systems for storage area networks.

     We operate in two segments -- the Semiconductor segment and the Storage
Area Network (SAN) Systems segment -- in which we offer products and services
for a variety of electronic systems applications. Our products are marketed
primarily to original equipment manufacturers (OEMs) who sell products targeted
for applications in four major markets, which are:

     - Consumer Products;

     - Communications;

     - Storage Components; and

     - Storage Area Network Systems.

     In the Semiconductor segment, we use advanced process technology and
comprehensive design methodologies to design, develop, manufacture and market
highly complex integrated circuits. These system-on-a-chip solutions include
both application specific integrated circuits, commonly referred to as ASICs and
standard products, as well as Redundant Array of Independent Disks (RAID) host
bus adapters and related products; and services. ASICs are designed for specific
applications defined by the customer, whereas standard products are for market
applications that we define. See also "Management's Discussion and Analysis of
Financial Condition and Results of Operations" in Item 7 of Part II herein.

     We have developed methods of designing integrated circuits based on a
library of building blocks of industry-standard electronic functions,
interfaces, and protocols. Among these is our CoreWare design methodology. Our
advanced submicron manufacturing process technologies allow our customers to
combine one or more CoreWare library elements with memory and their own
proprietary logic to integrate a highly complex, system-level solution on a
single chip. (Our G10, G11, G12 and Gflx submicron process technologies are more
fully described in the section on Manufacturing below.) We have developed and
use complementary metal oxide semiconductor (CMOS) process technologies to
manufacture our integrated circuits.

BUSINESS STRATEGY

  SEMICONDUCTOR BUSINESS STRATEGY

     Our objective is to continue to be an industry leader in the design and
manufacture of highly integrated, complex integrated circuits and other
electronic components and system-level products that provide our customers with
silicon-based system-level solutions. To achieve this objective, our business
strategy includes the following key elements:

     - Target Growth Markets and Selected Customers.  We concentrate our sales
       and marketing efforts on leading OEM customers in targeted growth
       markets, led by the communications, consumer, storage components, and
       storage area network systems applications. Our engineering expertise is
       focused on developing technologies that will meet the needs of
       leading-edge customers in order to succeed in these market areas.

     - Emphasize CoreWare Methodology and System-on-a-Chip Capability.  Our
       CoreWare design methodology enables the integration of one or more
       pre-designed circuit elements with customer-specified elements and memory
       to create system capabilities on a single chip. This results in higher
       product functionality, higher performance, greater differentiation, and
       faster time to market. We also have used this design methodology to
       develop proprietary standard products.

     - Promote Highly Integrated Design and Manufacturing Technology.  We use
       proprietary and leading third-party electronic design automation, or EDA,
       software design tools. Our design tool environment is highly integrated
       with our manufacturing process requirements so that it will accurately
       simulate product performance. This reduces design time and project cost.
       We continually evaluate and, as appropriate, develop expertise with
       third-party EDA tools from leading and emerging suppliers of such
       products.

     - Provide Flexibility in Design Engineering.  We engage with customers of
       our semiconductor products under various arrangements whereby the extent
       of the engineering support we provide will be determined in accordance
       with the customer's requirements. For example, a customer may primarily
       use its own engineers for substantial development of its product design
       and retain our support for silicon-specific engineering work. We also
       enter into engineering design projects, including those on a "turn-key"
       basis.

     - Maintain High-Quality and Cost-Effective Manufacturing.  We operate our
       own manufacturing facilities in order to control our deployment of
       advanced wafer fabrication technology, our manufacturing costs, and our
       response to customer delivery requirements. We also use independent wafer
       foundry services when appropriate and may seek to fill unused capacity in
       our own foundries by offering such services to third parties. We perform
       substantially all of our packaging, assembly, and final test operations
       through subcontractors in Asia. Our production operations in Gresham,
       Oregon, and Tsukuba, Japan, and our assembly and test subcontractors in
       Asia are ISO-9002 certified, an important international measure for
       quality.

                                        2
<PAGE>

     - Leverage Alliances with Key Partners.  We are continually seeking to
       establish relationships with key partners in a diverse range of
       semiconductor and storage-system technologies to promote new products,
       services, operating standards, and manufacturing capabilities and to
       avail ourselves of cost efficiencies that may be obtained through
       collaborative development.

     - Develop and Drive Industry Standards to Achieve Market Advantage.  We
       have been a leader in developing and promoting important industry
       standard architectures, functions, protocols, and interfaces. We believe
       that this strategy will enable us to quickly launch new standard-based
       products, allowing our customers to achieve time-to-market and other
       competitive advantages.

     - Operate Worldwide.  We market our products and engage with our customers
       on a worldwide basis through direct sales, marketing, and field technical
       staff and through independent sales representatives and distributors. Our
       network of design centers located in major markets allows us to provide
       customers with highly experienced engineers, to interact with customer
       engineering management and system architects, to develop designs for new
       products, and to provide continuing after-sale customer support.

     SAN SYSTEMS BUSINESS STRATEGY

     - Highly Leveraged Core Competencies.  In the SAN systems market, we
       leverage expertise used to develop our semiconductors, storage
       input/output components, storage management software, and storage systems
       in the development of scalable storage solutions. We use the full scope
       of our technical expertise to design and develop interoperable,
       easy-to-manage, leading price/performance products.

     - Modular Design Philosophy.  Our flexible approach to storage system
       design allows elements of a system to be configured and/or customized
       together or separately to meet customer requirements. Benefits to our
       customers include investment protection, reduced support costs, and a
       common management interface and features. This allows customers to start
       with pilot projects and later scale to full implementation.

     - Flexible Business Models.  Our strategy is to provide flexible,
       customizable solutions with room for value-added components, software,
       and services provided by the channel. Our modular product set allows OEMs
       and resellers to devise a solution to best meet their needs and to
       satisfy customers.

governmental regulations, tariff increases and other trade barriers and currency
fluctuations.

     We rely primarily on direct sales and marketing, but we also work with
independent distributors in North America, Europe, Japan and elsewhere in Asia.
Some of our distributors possess engineering capabilities and design and
purchase both ASICs and standard products from us for resale to their customers.
Other distributors focus solely on the sale of standard products. Our agreements
with distributors generally grant limited rights to return standard product
inventory and obtain credits for price reductions applicable to standard
products held in inventory. We maintain appropriate reserves to account for
these factors. However, owing to the relatively small quantities of products
held in inventory by our distributors, we believe that these arrangements do not
result in material financial exposure for our company.

  SAN SYSTEMS MARKETING AND DISTRIBUTION

     SAN systems products are sold worldwide both on a direct basis to OEMs and
through indirect channels to end-users. The MetaStor brand of scalable SAN
systems is exclusively marketed through a worldwide network of value-added
resellers, system integrators and distributors. We closely manage these
relationships to meet the diverse needs of end-users. Our marketing efforts are
driven by an industry-wide trend toward the implementation of storage area
networks to maximize performance, availability and efficiency.

     Our direct sales force provides customized SAN systems solutions generally
to large, well-known manufacturers of computer equipment. Our product
development strategy focuses on implementing the latest storage technologies to
improve the performance of our hardware and software storage solutions. As a
pioneer in the development of redundant array of independent disks (RAID)
technology, and as a member of the Fibre Channel Industry Association and
Storage Networking Industry Association, we are continually driving industry
standards for fibre channel and SAN solutions.

     In January 2002, the Company and Storage Technology Corporation
(StorageTek) announced an alliance under which StorageTek will become the
worldwide master distributor of co-branded open storage products. Further, the
companies will market a full line of scalable, high performance, high
availability disk storage systems that will be engineered and manufactured by
LSI Logic Storage Systems and sold, installed and supported by StorageTek.

CUSTOMERS

     We seek to leverage our expertise in the fields of communications,
consumer, storage components and SAN systems by marketing our products and
services to market leaders. Our strategic-account focus is on larger, well-known
companies that produce high-volume products incorporating our semiconductors and
storage system products. We recognize that this strategy may result in increased
dependence on a limited number of customers for a substantial portion of our
revenues. It is possible that we will not achieve significant sales volumes from
one or more of the customers we have selected. While this could result in lower
revenues and higher unit costs owing to an under-utilization of our resources,
we believe this strategy provides us with the greatest opportunity to drive
further growth in sales and unit volumes.

     We operate in a rigorous competitive environment and our continued success
requires that we consistently develop and manufacture products that meet the
needs of our customers. There is no assurance that we will achieve significant
sales revenues from one or more of our strategic customers. This could result in
lower revenues for our company.

     In 2001, Sony accounted for approximately 18% of our consolidated revenues.
No other customer accounted for greater than 10% of consolidated revenues.

MANUFACTURING

  SEMICONDUCTOR MANUFACTURING

     Our semiconductor manufacturing operations convert a design into packaged
silicon chips and support customer requirements for volume production.
Manufacturing begins with fabrication of custom-diffused silicon wafers. Layers
of metal interconnects are deposited onto the wafer and patterned using
customized photo masks. Wafers are then tested and cut into die. Die that pass
initial tests are then sent to the assembly process where the fabricated
circuits are assembled into plastic package or laminate substrate ball grid
array. The finished devices undergo additional testing and quality assurance
before shipment. Dedicated computer systems are used in this comprehensive
testing sequence. The test programs use the basic functional test criteria from
the design simulation. The customer specifies the functional test criteria for
ASIC circuits.

     We own and operate manufacturing operations in the United States, Japan,
and Hong Kong. In January 2002, we announced a restructuring of the Japan
manufacturing facility. In addition, we utilize external wafer foundries located
in Taiwan and Malaysia. We use high-performance CMOS process technologies in the
volume manufacture of our products. The production operations are fully
computer-integrated to increase efficiency and reduce costs.

     Semiconductor process technologies are identified in terms of the size of
channel length within the transistors, measured in millionths of a meter called
"microns." The measurement of the channel length is expressed in two ways:
effective electrical channel length and drawn gate length. The effective
electrical channel length is smaller than the drawn gate length. In this Report
on Form 10-K, we use the electrical effective channel length to identify our
process technologies.

     Our advanced submicron manufacturing processes are capable of producing
products with an effective electrical channel length within each transistor as
small as 0.13-micron in our G12 technology. Our 0.18-micron (G11 process
technology) allows up to 24 million usable gates on a single chip. Our G10
process technology is capable of producing 0.25-micron effective channel length
products. We have a joint development technology for Gflx, a new flexible
process technology capable of combining all of the system functions to create
totally new classes of products on a single chip. The Gflx technology is more
than twice as dense as the previous generation G12 process technology, allowing
designers to incorporate added functions onto a single chip. The 0.10-micron
effective channel length Gflx process technology offers 78 million usable logic
gates. These advanced process technologies allow for greater circuit density and
increased functionality on a single chip.

     A majority of our wafers are fabricated in our factories in Gresham, Oregon
and Tsukuba, Japan. The rest of the wafers are manufactured at our external
wafer foundries in Taiwan and Malaysia. The factories in Gresham and Tsukuba are
ISO-9002 certified -- an important internationally recognized standard for
quality. In July 1999, the older of the two Tsukuba factories, which produced
0.38-micron products, was closed after eleven years of service. This action was
taken as part of a comprehensive restructuring and cost reduction plan commenced
in 1998. In January 2002, the Company announced a restructuring of the Japan
manufacturing facility. In October 2001, the manufacturing facility in Colorado
Springs, Colorado, which produced 0.65-micron, 0.54-micron and 0.25-micron
wafers, was closed after ten years of service. This action was taken as part of
a comprehensive restructuring and cost reduction plan that commenced in April
2001.

     Our newest manufacturing facility is located in Gresham, Oregon on 325
acres outside of Portland. This facility is equipped for advanced manufacturing
operations and is designed to accommodate our expansion requirements well into
the foreseeable future. The plant is equipped to produce eight-inch wafers
hosting products manufactured to the G10, G11, G12, and Gflx processes.

     On April 4, 2001, we announced a co-development and foundry supply
agreement with Taiwan Semiconductor Manufacturing Company Ltd. (TSMC). This
agreement is part of our strategy to "outsource," that is to procure a larger
portion of our wafer requirements from external sources. As a result of our

                                        8
<PAGE>

joint development efforts with TSMC we anticipate purchasing, consistent with
our "outsourcing" strategy, such portion of our wafer volume requirements based
on the 0.13-micron process technology that we do not manufacture ourselves. In
addition, we anticipate being able to defer the need to expand our manufacturing
capacity for the 0.13-micron technology beyond the time when products designed
for that technology would begin volume production. We also anticipate
collaborating with TSMC on further advancement in wafer fabrication technology.

     Our fixed costs for manufacturing are high and are expected to remain high
because we must continually make significant capital expenditures and add new
advanced capacity in order to remain competitive. If demand for our products
does not absorb the additional capacity, the increase in fixed costs and
operating expenses related to increases in production capacity may result in a
material adverse impact on our operating results and financial condition.
(Additional risk factors are set forth in the Risk Factors section below.)

     We offer a wide range of packaging solutions for system-on-a-chip designs.
We have also developed a high-performance, high-density interconnect packaging
technology, known as flip chip, which essentially replaces the wires that
connect the edge of the die to a package with solder bumps spread over the
entire external surface of the die. This technology enables us to reach
exceptional performance and lead-count levels in packages required for process
technologies of 0.18 micron and below. We also offer a mini-ball grid array
package that features a smaller package size without sacrificing electrical and
thermal performance. We also offer a wide array of plastic wire-bond packaging
options.

     Final assembly (i.e., assembly in a plastic or laminate substrate package)
and test operations are conducted by our Hong Kong affiliate through independent
subcontractors in the Philippines, Malaysia, South Korea, Taiwan, and Hong Kong.
We also utilize subcontractors in Thailand for the assembly and test of our host
adapter boards.

     Both manufacturing and sales of our semiconductor products may be impacted
by political and economic conditions abroad. Protectionist trade legislation in
either the United States or foreign countries, such as a change in the current
tariff structures, export compliance laws or other trade policies, could
adversely affect our ability to manufacture or sell products in or into foreign
markets. We cannot guarantee that current arrangements with our component
suppliers or assembly, testing and packaging subcontractors will continue, and
we do not maintain an extensive inventory of assembled components. The failure
to secure assembly and test capacity could affect our sales and result in a
material adverse impact on our operating results and financial condition.

     Development of advanced manufacturing technologies in the semiconductor
industry frequently requires that critical selections be made as to those
vendors from which essential equipment (including future enhancements) and
after-sales services and support will be purchased. Some of our equipment
selections require that we procure certain specific types of materials or
components specifically designed to our specifications. Therefore, when we
implement specific technology choices, we may become dependent upon certain
sole-source vendors. Accordingly, our capability to switch to other technologies
and vendors may be substantially restricted and a switch may involve significant
expense and could delay our technology advancements and decrease manufacturing
capabilities.

     The semiconductor equipment and materials industries also include a number
of vendors that are relatively small and have limited resources. Several of
these vendors supply us with equipment and/or services. We do not have long-term
supply or service agreements with vendors of certain critical items, and
shortages could occur in various essential materials due to interruption of
supply or increased demand in the industry. Given the limited number of
suppliers of certain of the materials and components used in our products, if we
experience difficulty in obtaining essential materials in the future we cannot
be assured that alternative suppliers will be available to meet our needs. Such
disruptions could materially affect our operations, which could have a material
adverse impact on our operating results and financial condition.

     The primary raw materials used in the manufacturing of semiconductors
include raw wafers and certain chemicals used in the processing of
semiconductors. The raw wafers are obtained primarily from suppliers in Japan
and their U.S. subsidiaries, whereas other material inputs are obtained on a
local basis. Our operations

                                        9
<PAGE>

also depend upon a continuing adequate supply of electricity, natural gas and
water. These energy sources have historically been available on a continuous
basis and in adequate quantities for our needs. However, given the recent power
shortage in California, it is possible that other areas of the country,
including Oregon, may experience similar shortages. An interruption in the
supply of raw materials or energy inputs for any reason would have an adverse
effect on our manufacturing operations.

     Our manufacturing facilities incorporate sophisticated computer integrated
manufacturing systems, which depend upon a mix of our proprietary software and
systems and software purchased from third parties. Failure of these systems
would cause a disruption in the manufacturing process and could result in a
delay in completion and shipment of products.

  SAN SYSTEMS MANUFACTURING

     The manufacturing of SAN systems products involves the assembly and testing
of components, including our semiconductors, which are then integrated into
final products.

     SAN systems product and manufacturing designs are highly modularized for
flexibility. Our manufacturing operations include Configure to Order and
Assemble to Order capabilities. These processes have been implemented in an
effort to reduce requisite lead times for the delivery of product.

     - US Manufacturing.  Our US manufacturing facility in Wichita, Kansas,
       assembles and tests high performance array controllers, rack-mount
       modules and complete storage systems.

     ISO-9001 certification at our Kansas manufacturing facility has been
maintained since April 1992. This facility is currently certified ISO 9001:2000
compliant as of October 2001. Product quality is achieved through employee
training, automated testing, and sample auditing. Supply line management extends
quality through the component and subassembly supplier base with continuous
reporting and supplier/product qualification programs.

     - European Manufacturing.  The Company maintains a manufacturing facility
       in Cork, Ireland through an agreement with Flextronics International Ltd.
       This facility is capable of assembly and testing of high performance
       array controllers, rack-mount modules and complete storage systems.

     The Irish site was established to provide flexibility in satisfying
European demand and to serve as a backup site in the event natural or human-made
disasters affect the manufacturing capacity of the Wichita, Kansas facility. The
Irish site is certified as ISO 9001:2000 compliant as of December 2001.

     Our SAN systems manufacturing operations are based primarily on an
integrated Enterprise Resource Planning (ERP) manufacturing application system
purchased from a third party. This ERP system is augmented with several of our
proprietary software tools that support the production process through automated
product configuration and automated electronic testing. Failure of these systems
would cause a disruption in the manufacturing process and could result in delays
of product shipments and/or customer billings.

     Our manufacturing facility in Wichita, Kansas depends upon a continuous
supply of electricity from a single utility provider. Any natural or manmade
disruptions could materially affect our operating results and financial
condition.

BACKLOG

  SEMICONDUCTOR BACKLOG

     In the Semiconductor segment, we generally do not have long-term volume
purchase contracts with our customers. Instead, customers place purchase orders
that are subject to acceptance by us. The timing of the design activities for
which we receive payment and the placement of orders included in our backlog at
any particular time is generally within the control of the customer. For
example, there could be a significant time lag between the commencement of
design work and the delivery of a purchase order for the units of a developed
product. Also, customers may from time to time revise delivery quantities or
delivery schedules to

                                        10
<PAGE>

reflect their changing needs. For these reasons, our backlog as of any
particular date is not a meaningful indicator of future sales.

  SAN SYSTEMS BACKLOG

     In the SAN Systems segment, our large customers who are original equipment
manufacturers place orders that are subject to acceptance by us in accordance
with their requirements and our delivery lead time capabilities. In our reseller
channel, we typically receive requests for product to be delivered within two
weeks or less. Accordingly, our backlog as of any particular date is not a
meaningful indicator of future sales.

COMPETITION

  SEMICONDUCTOR COMPETITORS

     The semiconductor industry is intensely competitive and characterized by
constant technological change, rapid product obsolescence, evolving industry
standards and price erosion. Many of our competitors are larger, diversified
companies with substantially greater financial resources. Some of these also are
customers who have internal semiconductor design and manufacturing capacity. We
also compete with smaller and emerging companies whose strategy is to sell
products into specialized markets or to provide a portion of the products and
services that we offer.

     Our major competitors include large domestic companies such as IBM
Corporation, Agere Systems, Inc., Texas Instruments, Inc., and Agilent
Technologies, Inc. Other competitors in strategic markets include Adaptec, Inc.,
QLogic Corporation, PMC-Sierra, Inc., Broadcom Corporation, and Conexant
Systems, Inc.

     We also face competition from certain large foreign corporations, including
Philips Electronics, N.V., ST Microelectronics, S.A., and Toshiba Corporation.

     The principal competitive factors in the industry include:

     - design capabilities;

     - differentiating product features;

     - product performance characteristics;

     - time to market;

     - price;

     - manufacturing processes; and

     - utilization of emerging industry standards.

     We believe that we presently compete favorably with respect to these
factors. It is possible, however, that other custom design solutions will be
developed by our competitors that could have a material adverse impact on our
competitive position. Our competitors may also decide from time to time to
aggressively lower prices of products that compete with us in order to sell
related products or achieve strategic goals. Strategic pricing by competitors
can place strong pricing pressure on our products in certain transactions,
resulting in lower selling prices and lower gross profit margins for those
transactions.

     The markets into which we sell our semiconductor products are subject to
severe price competition. We expect to continue to experience declines in the
selling prices of our semiconductor products over the life cycle of each
product. In order to offset or partially offset declines in the selling prices
of our products, we must continue to reduce the costs of products through
product design changes, manufacturing process changes, and yield improvements.
We do not believe that we can continually achieve cost reductions that fully
offset the price declines of our products, and therefore gross profit margin
percentages will generally decline for existing products over their life cycles.

                                        11
<PAGE>

     We are increasingly emphasizing our CoreWare design methodology and
system-on-a-chip capability. Competitive factors that are important to the
success of this strategy include:

     - selection, quantity and quality of our CoreWare library elements;

     - our ability to offer our customers systems level expertise; and

     - quality of software to support system-level integration.

     Although there are other companies that offer similar types of products and
related services, we believe that we currently compete favorably with those
companies. However, competition in this area is increasing, and there is no
assurance that our CoreWare methodology approach and product offerings will
continue to receive market acceptance. Customers in our targeted markets
frequently require system-level solutions. Our ability to deliver complete
solutions may also require that we succeed in obtaining licenses to necessary
software and integrating this software with our semiconductors.

  SAN SYSTEMS COMPETITORS

     The SAN systems market is characterized by many of the same pressures found
in the semiconductor industry. We believe that important competitive factors in
the storage-systems market include the following:

     - product performance and price;

     - support for new industry and customer standards;

     - scalability;

     - interoperability with other network devices;

     - features and functionality;

     - availability;

     - reliability, technical service, and support;

     - quality of system integration;

     - existence and accessibility of differentiating features; and

     - quality and availability of supporting software.

     Our failure to compete successfully with respect to any of these or other
factors could have a material adverse effect on our results of operations and
financial condition. Our SAN systems products compete primarily with products
from independent storage providers such as EMC Corporation, Hitachi Data Systems
Corporation and MTI Technology Corporation. In addition, many of our current and
potential customers in this market have internal storage divisions that produce
products that compete directly or indirectly with our storage-system products.
There is no assurance that these customers, which include Hewlett-Packard
Company, IBM Corporation, Sun Microsystems, Inc., Silicon Graphics and NCR, will
continue to purchase our storage systems products.

PATENTS, TRADEMARKS AND LICENSES

     The Company has filed a number of patent applications and currently holds
numerous patents, expiring from 2002 to 2021, relating to certain of our
products and technologies in both the Semiconductor and the SAN Systems
segments. In both segments, we also maintain trademarks for certain of our
products and services and claim copyright protection for certain proprietary
software and documentation. Patents, trademarks, and other forms of protection
for our intellectual property are important, but we believe our future success
principally depends upon the technical competence and creative skills of our
personnel.

     In the Semiconductor segment, we also protect our trade secret and other
proprietary information through agreements with our customers, suppliers,
employees, and consultants and through other security measures. We have entered
into certain cross-license agreements that generally provide for the
non-exclusive

                                        12
<PAGE>

licensing of rights to design, manufacture, and sell products and, in some
cases, for cross-licensing of future improvements developed by either party.

     We continue to expand our portfolio of patents and trademarks. We offer a
staged incentive to engineers to identify, document and submit invention
disclosures. We have developed an internal review procedure to maintain a high
level of disclosure quality and to establish priorities and plans for filings
both in the United States and abroad. The review process is based solely on
engineering and management judgment, with no assurance that a specific filing
will issue, or if issued, will deliver any lasting value to us. There is no
assurance that the rights granted under any patents will provide competitive
advantages to us or will be adequate to safeguard and maintain our proprietary
rights. Moreover, the laws of certain countries in which our products are or may
be manufactured or sold may not protect our products and intellectual property
rights to the same extent as the U.S. legal system.

     As is typical in the high technology industry, from time to time we have
received communications from other parties asserting that certain of our
products, processes, technologies or information infringe upon their patent
rights, copyrights, trademark rights or other intellectual property rights. We
regularly evaluate such assertions. In light of industry practice, we believe
with respect to existing or future claims that any licenses or other rights that
may be necessary can generally be obtained on commercially reasonable terms.
Nevertheless, there is no assurance that licenses will be obtained on acceptable
terms or that a claim will not result in litigation or other administrative
proceedings.

     In the SAN Systems segment, we own a portfolio of patents and patent
applications concerning a variety of storage technologies. We also maintain
trademarks for certain of our products and services and claim copyright
protection for certain proprietary software and documentation. Similar to the
Semiconductor segment, we protect our trade secrets and other proprietary
information through agreements and other security measures, and have implemented
internal procedures to identify patentable inventions and pursue protection in
selected jurisdictions.

     Please see Item 3, Legal Proceedings for information regarding pending
patent litigation against LSI; please also refer to the additional risk factors
set forth in the Risk Factors section; and Note 12 of the Notes to Consolidated
Financial Statements for additional information.

RESEARCH AND DEVELOPMENT

     Our industry is characterized by rapid changes in products, design tools,
and process technologies. We must continue to improve our existing products,
design-tool environment and process technologies and to develop new ones in a
cost-effective manner to meet changing customer requirements and emerging
industry standards. If we are not able to successfully introduce new products,
design tools and process technologies or to achieve volume production of
products at acceptable yields using new manufacturing processes, there could be
a material adverse impact on our operating results and financial condition.

     We operate research and development facilities in California, Colorado,
Oregon and Kansas. The following table shows our expenditures on research and
development activities for each of the last three fiscal years (in thousands).

<Table>

     Research and development expenses primarily consist of salaries and related
costs of employees engaged in ongoing research, design and development
activities and subcontracting costs.

WORKING CAPITAL

     Information regarding our working capital practices is incorporated herein
by reference from Item 7 of Part II hereof under the heading "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Financial Condition and Liquidity".

FINANCIAL INFORMATION ABOUT GEOGRAPHIC AREAS

     This information is included in Note 11 ("Segment Reporting") of Notes to
Financial Statements and Supplementary Data, which information is incorporated
herein by reference to Item 8 of Part II hereof.

ENVIRONMENTAL REGULATION

     Federal, state and local regulations, in addition to those of other
nations, impose various environmental controls on the use and discharge of
certain chemicals and gases used in semiconductor processing. Our facilities
have been designed to comply with these regulations, and we believe that our
activities conform to current environmental regulations. However, increasing
public attention has been focused on the environmental impact of electronics and
semiconductor manufacturing operations. While to date we have not experienced
any material adverse impact on our business from environmental regulations, we
cannot assure you that such regulations will not be amended so as to impose
expensive obligations on us in the future. In addition, violations of
environmental regulations or impermissible discharges of hazardous substances
could result in the necessity for the following actions:

     - additional capital improvements to comply with such regulations or to
       restrict discharges;

     - liability to our employees and/or third parties; and/or

     - business interruptions as a consequence of permit suspensions or
       revocations or as a consequence of the granting of injunctions requested
       by governmental agencies or private parties.

EMPLOYEES

     As of December 31, 2001, we had 6,737 full-time employees.

     In January 2002, the Company announced a series of restructuring actions to
tailor the Company to its current lower level of revenues. These actions
included reducing the worldwide workforce by approximately 1,400 positions or 20
percent of the Company's workforce.

     Our future success depends upon the continued service of our key technical
and management personnel and on our ability to continue to attract and retain
qualified employees, particularly those highly skilled design, process, and test
engineers involved in the manufacture of existing products and the development
of new products and processes. We currently have favorable employee relations,
but the competition for such personnel is intense, and the loss of key employees
or the inability to hire such employees when needed could have a material
adverse input on our business and financial condition.

SEASONALITY

     The Company's business is largely focused on the communications and
consumer products markets. As a result, the Company's results may follow a
seasonal pattern, with stronger growth in the second half of the year,
reflecting the buying patterns of the Company's customers.

                                        14
<PAGE>

                                  RISK FACTORS

     Keep these risk factors in mind when you read "forward-looking" statements
elsewhere in this Form 10-K and in the documents incorporated herein by
reference. These are statements that relate to our expectations for future
events and time periods. Generally, the words, "anticipate," "expect," "intend'
and similar expressions identify forward-looking statements. Forward-looking
statements involve risks and uncertainties, and actual results could differ
materially from those anticipated in the forward-looking statements.

     We operate in a cyclical industry and a general economic downturn may
reduce our revenues.  The semiconductor industry is cyclical in nature and is
characterized by wide fluctuations in product supply and demand. In 2001, the
economic growth in the United States slowed significantly, which in turn, led to
a severe downturn in the semiconductor industry. During a period of industry
overcapacity, profitability can drop sharply as factory utilization declines and
high fixed costs of operating wafer fabrication facilities are spread over a
lower net revenue base. The Company's overall business bottomed in 2001 and the
Company is on track to restore profitability in the near future. However, any
additional terrorist activities may adversely affect the U.S. economy. In turn,
we may face interruption of production and services due to increased security
measures in light of recent terrorist activities, which may affect the recovery
of the Company in 2002 and adversely impact its operating results and financial
condition.

     Our product and process development activities occur in a highly
competitive environment characterized by rapid technological change.  The
Semiconductor and SAN Systems segments in which we conduct business are
characterized by rapid technological change, short product cycles and evolving
industry standards. We believe our future success depends, in part, on our
ability to improve on existing technologies and to develop and implement new
ones in order to continue to reduce semiconductor chip size and improve product
performance and manufacturing yields. We must also be able to adopt and
implement emerging industry standards and to adapt products and processes to
technological changes. If we are not able to implement new process technologies
successfully or to achieve volume production of new products at acceptable
yields, our operating results and financial condition will be adversely
impacted.

     In addition, we must continue to develop and introduce new products that
compete effectively on the basis of price and performance and that satisfy
customer requirements. We continue to emphasize engineering development and
acquisition of CoreWare building blocks and integration of our CoreWare
libraries into our design capabilities. Our cores and standard products are
intended to be based upon industry standard functions, interfaces and protocols
so that they are useful in a wide variety of systems applications. Development
of new products and cores often requires long-term forecasting of market trends,
development and implementation of new or changing technologies and a substantial
capital commitment. We cannot assure you that the cores or standard products
that we select for investment of our financial and engineering resources will be
developed or acquired in a timely manner or will enjoy market acceptance.

     We operate highly complex and costly manufacturing facilities.  The
manufacture and introduction of our products is a complicated process. We
confront challenges in the manufacturing process that require us to:

     - maintain a competitive manufacturing cost structure;

     - implement the latest process technologies required to manufacture new
       products;

     - exercise stringent quality control measures to ensure high yields;

     - effectively manage the subcontractors engaged in the test and assembly of
       products; and

     - update equipment and facilities as required for leading edge production
       capabilities.

     We do not control the timing or size of orders for our products.  We
generally do not have long-term volume production contracts with our customers.
There is a risk that we will be unable to meet sudden increases in demand beyond
our current manufacturing capacity, which may result in additional capital
expenditures and production costs. On the other hand, order volumes below
anticipated levels may result in the under-utilization of our manufacturing
facilities, resulting in higher per unit costs, which could adversely affect our
operating results and financial condition.

                                        15

     Our manufacturing facilities are subject to disruption.  Our newest wafer
fabrication site located in Gresham, Oregon is a highly complex,
state-of-the-art facility. Anticipated production rates depend upon the reliable
operation and effective integration of a variety of hardware and software
components. There is no assurance that all of these components will be fully
functional or successfully integrated on time or that the facility will achieve
the forecasted yield targets. The capital expenditures required to bring the
facility to full operating capacity may be greater than we anticipate and result
in lower margins.

     Operations at any of our primary manufacturing facilities, or at any of our
test and assembly subcontractors, may be disrupted for reasons beyond our
control, including work stoppages, fire, earthquake, floods or other natural
disasters. Recently, California experienced a power shortage. Any future
shortages could subject us to electrical "blackouts" or other unscheduled
interruption of electrical power.

     We outsource a substantial portion of wafers manufactured.  The Company has
developed outsourcing arrangements for the manufacture of some of its products
based on a process technology that the Company does not possess. There is no
assurance that the third party manufacturer will be able to produce and deliver
wafers that meet the Company's specifications or that it will be able to provide
successfully the process technology it has committed. If the third party is not
able to deliver products and process technology on a timely and reliable basis,
the Company's results of operations could be adversely affected.

     We have significant capital requirements to maintain and grow our
business.  In order to remain competitive, we must continue to make significant
investments in new facilities and capital equipment. During 2002, we anticipate
that we will spend less than $200 million on capital assets and that we will be
required to spend potentially larger amounts thereafter. In addition, the high
level of capital expenditures required to remain competitive results in
relatively high fixed costs. If demand for our products does not absorb
additional capacity, the fixed costs and operating expenses related to increases
in our production capacity could have a material adverse impact on our operating
results and financial condition.

     We finance our capital expenditure needs from operating cash flows, bank
financing and capital market financing. As of December 31, 2001, we had
convertible notes outstanding of approximately $1.3 billion. As of December 31,
2001, we have two operating leases financed by several commercial banks. We may
need to seek additional equity or debt financing from time to time, including
issuance of warrants and cannot be certain that additional financing will be
available on favorable terms. Moreover, any future equity or convertible debt
financing will decrease the percentage of equity ownership of existing
stockholders and may result in dilution, depending on the price at which the
equity is sold or the debt is converted.

     We are exposed to fluctuations in foreign currency exchange rates.  We have
international subsidiaries and distributors that operate and sell our products
globally. Further, we purchase a substantial portion of our raw materials and
manufacturing equipment from foreign suppliers, and incur labor and other
operating costs in foreign currencies, particularly in our Japanese
manufacturing facilities. As a result, we are exposed to the risk of changes in
foreign currency exchange rates or declining economic conditions in these
countries.

     We do business in Europe and face risks associated with the Euro.  A new
European currency was implemented in January 1999 to replace the separate
currencies of eleven western European countries, and beginning in January 2002,
was the only effective currency in these countries. This has required changes in
our operations as we modified systems and commercial arrangements to deal with
the new currency.

     We procure parts and raw materials from limited domestic and foreign
sources.  We use a wide range of parts and raw materials in the production of
our semiconductors, host adapter boards, and storage systems, including silicon
wafers, processing chemicals, and electronic and mechanical components. We do
not generally have guaranteed supply arrangements with our suppliers and do not
maintain an extensive inventory of parts and materials for manufacturing. We
purchase some of these parts and materials from a limited number of vendors and
some from a single supplier. On occasion, we have experienced difficulty in
securing an adequate volume and quality of parts and materials. There is no
assurance that, if we have difficulty in obtaining parts or materials in the
future, alternative suppliers will be available, or that these suppliers will
provide parts and materials in a timely manner or on favorable terms. As a
result, we may be adversely affected by delays in new and current product
shipments. If we cannot obtain adequate materials for

                                        16
<PAGE>

manufacture of our products, there could be a material adverse impact on our
operating results and financial condition.

     We operate in highly competitive markets.  We compete in markets that are
intensely competitive and that exhibit both rapid technological change and
continual price erosion. Our competitors include many large domestic and foreign
companies that have substantially greater financial, technical and management
resources than we do. Several major diversified electronics companies offer ASIC
products and/or other standard products that are competitive with our product
lines. Other competitors are specialized, rapidly growing companies that sell
products into the same markets that we target. Some of our large customers may
develop internal design and production capabilities to manufacture their own
products, thereby displacing our products. There is no assurance that the price
and performance of our products will be superior relative to the products of our
competitors. As a result, we may experience a loss of competitive position that
could result in lower prices, fewer customer orders, reduced revenues, reduced
gross profit margins and loss of market share. To remain competitive, we
continually evaluate our worldwide operations, looking for additional cost
savings and technological improvements.

     Our future competitive performance depends on a number of factors,
including our ability to:

     - properly identify target markets;

     - accurately identify emerging technological trends and demand for product
       features and performance characteristics;

     - develop and maintain competitive products;

     - enhance our products by adding innovative features that differentiate our
       products from those of our competitors;

     - bring products to market on a timely basis at competitive prices;

     - respond effectively to new technological changes or new product
       announcements by others;

     - adapt products and processes to technological changes; and

     - adopt and/or set emerging industry standards.

     We may not meet our design, development and introduction schedules for new
products or enhancements to our existing and future products. In addition, our
products may not achieve market acceptance or sell at favorable prices.

     We are dependent on a limited number of customers.  We are increasingly
dependent on a limited number of customers for a substantial portion of revenues
as a result of our strategy to focus our marketing and selling efforts on
select, large-volume customers. One customer represented 18% of our total
consolidated revenues for the year ended December 31, 2001. In the Semiconductor
segment, one customer represented 21% of total Semiconductor revenues for the
year ended December 31, 2001. In the SAN Systems segment, there were two
customers with revenues representing 21% each, and one customer with revenues
representing 13% of total SAN Systems revenues for the year ended December 31,
2001.

     Our operating results and financial condition could be affected if:

     - we do not win new product designs from major customers;

     - major customers reduce or cancel their existing business with us;

     - major customers make significant changes in scheduled deliveries; or

     - there are declines in the prices of products that we sell to these
       customers.

     We utilize indirect channels of distribution over which we exercise limited
control.  We derive a material percentage of product revenues from independent
reseller and distributor channels. Our financial results could be adversely
affected if our relationship with these resellers or distributors were to
deteriorate or if the financial condition of these resellers or distributors
were to decline. Given the current economic environment, the risk of

                                        17
<PAGE>

distributors going out of business is significantly increased. In addition, as
our business grows, we may have an increased reliance on indirect channels of
distribution. There can be no assurance that we will be successful in
maintaining or expanding these indirect channels of distribution. This could
result in the loss of certain sales opportunities. Furthermore, the partial
reliance on indirect channels of distribution may reduce our visibility with
respect to future business, thereby making it more difficult to accurately
forecast orders.

     Our Company operations are affected by cyclical fluctuations.  The
Semiconductor and SAN Systems segments in which we compete are subject to
cyclical fluctuations in demand. In 2001, we experienced declines in sales or
the prices of our products as a result of the following:

     - rapid technological change, product obsolescence, and price erosion in
       our products;

     - maturing product cycles in our products or products sold by our
       customers;

     - increases in worldwide manufacturing capacity for semiconductors,
       resulting in declining prices; reduced product demand;

     - excess inventory within the supply chain; and

     - decline of the United States and worldwide economy, causing declines in
       our product markets or the markets of our suppliers and customers.

     The semiconductor industry has in the past experienced periods of rapid
expansion of production capacity. Even when the demand for our products remains
constant, the availability of additional excess production capacity in the
industry creates competitive pressure that can degrade pricing levels, which can
reduce revenues. Furthermore, customers who benefit from shorter lead times may
defer some purchases to future periods, which could affect our demand and
revenues for the short term. As a result, we may experience downturns or
fluctuations in demand in the future and experience adverse effects on our
operating results and financial condition.

     We engage in acquisitions and alliances giving rise to economic and
technological risks.  We intend to continue to make investments in companies,
products and technologies, either through acquisitions or investment alliances.
Acquisitions and investment activities often involve risks, including the need
to:

     - acquire timely access to needed capital for investments related to
       acquisitions and alliances;

     - conduct acquisitions that are timely relative to existing business
       opportunities;

     - successfully prevail over competing bidders for target acquisitions at an
       acceptable price;

     - invest in companies and technologies that contribute to the growth of our
       business;

     - retain the key employees of the acquired operation;

     - incorporate acquired operations into our business and maintain uniform
       standards, controls, and procedures; and

     - develop the capabilities necessary to exploit newly acquired
       technologies.

     Mergers and acquisitions of high-technology companies bear inherent risks.
No assurance can be given that our previous or future acquisitions will be
successful and will not materially adversely affect our business, operating
results or financial condition. We must manage any growth effectively. Failure
to manage growth effectively and to integrate acquisitions could adversely
affect our operating results and financial condition.

     There is uncertainty associated with our research and development
investments.  Our research and development activities are intended to maintain
and enhance our competitive position by utilizing the latest advances in the
design and manufacture of semiconductors and storage systems including
networking, communications and storage technologies. Technical innovations are
inherently complex and require long development cycles and the commitment of
extensive engineering resources. We must incur substantial research and
development costs to confirm the technical feasibility and commercial viability
of a product that in the end may not be successful. If we are not able to
successfully and timely complete our research and

                                        18
<PAGE>

development programs, we may face competitive disadvantages. There is no
assurance that we will recover the development costs associated with such
programs or that we will be able to secure the financial resources necessary to
fund future research and development efforts.

     The price of our securities may be subject to wide fluctuations.  Our stock
has experienced substantial price volatility, particularly as a result of
quarterly variations in results, the published expectation of analysts, and as a
result of announcements by our competitors and us. In addition, the stock market
has experienced price and volume fluctuations that have affected the market
price of many technology companies, in particular, and that have often been
unrelated to the operating performance of such companies. In addition, the price
of our securities may also be affected by general global, economic and market
conditions, and the cost of operations in one or more of our product markets.
While we cannot predict the individual effect that these factors may have on the
price or our securities, these factors, either individually or in the aggregate,
could result in significant variations in price during any given period of time.
These fluctuations in our stock price also impact the price of our outstanding
convertible securities and the likelihood of the convertible securities being
converted into cash or equity. If we are required to redeem any of the
convertible securities for cash it may affect our liquidity position.

     Our global operations expose the Company to numerous international business
risks.  We have substantial business activities in Asia and Europe. Both
manufacturing and sales of our products may be adversely impacted by changes in
political and economic conditions abroad. A change in the current tax laws,
tariff structures, export laws, regulatory requirements or trade policies in
either the United States or foreign countries could adversely impact our ability
to manufacture or sell our products in foreign markets. Moreover, a significant
decrease in sales by our customers to end users in either Asia or Europe could
result in a decline in orders.

     We subcontract test and assembly functions to independent companies located
in Asia. A reduction in the number or capacity of qualified subcontractors or a
substantial increase in pricing could cause longer lead times, delays in the
delivery of products to customers, or increased costs.

     The high technology industry in which we operate is prone to intellectual
property litigation.  Our success is dependent in part on our technology and
other proprietary rights, and we believe that there is value in the protection
afforded by our patents, patent applications and trademarks. However, the
industry is characterized by rapidly changing technology and our future success
depends primarily on the technical competence and creative skills of our
personnel, rather than on patent and trademark protection.

     As is typical in the high technology industry, from time to time we have
received communications from other parties asserting that certain of our
products, processes, technologies or information infringe upon their patent
rights, copyrights, trademark rights or other intellectual property rights. We
regularly evaluate such assertions. In light of industry practice, we believe
with respect to existing or future claims that any licenses or other rights that
may be necessary can generally be obtained on commercially reasonable terms.
Nevertheless, there is no assurance that licenses will be obtained on acceptable
terms or that a claim will not result in litigation or other administrative
proceedings. Resolution of whether the Company's product or intellectual
property has infringed on valid rights held by others could have a material
adverse effect on the Company's financial position or results of operation and
may require material changed in production processes and products

     See Item 3 "Legal Proceedings" contained in Part I of this Report.

     We must attract and retain key employees in a highly competitive
environment.  Our employees are vital to our success and our key management,
engineering and other employees are difficult to replace. We do not generally
have employment contracts with our key employees. We do, however, maintain key
person life insurance for one of our employees. The expansion of high technology
companies in Silicon Valley, Colorado, Oregon and elsewhere where we operate our
business has increased demand and competition for qualified personnel, and
despite the economic slowdown, competition for these personnel is intense. Our
continued growth and future operating results will depend upon our ability to
attract, hire and retain significant numbers of qualified employees.

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

ITEM 2.  PROPERTIES

     The Company's Milpitas facilities are leased and contain the Company's
corporate executive headquarters (for both the Semiconductor segment and the SAN
Systems segment), administration and engineering offices. The Company maintains
leased facilities in Fremont California, housing engineering offices, logistics
and warehouses.

     The Company owns the land and buildings housing its manufacturing
facilities for the Semiconductor segment in Gresham, Oregon, Tsukuba, Japan,
Fort Collins, Colorado, and owns the manufacturing control, assembly and test
facilities in Tsuen Wan, Hong Kong.

     In April 2001, the Company announced the closure of its Colorado Springs
fabrication facility in August 2001. In May 2001, the Company entered into a
definitive agreement to sell the facility to a third party. On August 1, 2001,
the Company announced the termination of the agreement to sell the facility. The
Company closed the facility in October 2001 and intends to dispose the assets
within the next 12 months.

     In September 2001, the Company announced the consolidation of its U.S.
manufacturing operations at Gresham, Oregon, and the transfer of process
research and development from Santa Clara, California, to Gresham, Oregon. As a
result, the Company closed the Santa Clara manufacturing facility. The lease for
this facility will expire in 2003. The Company does not plan on subleasing this
facility at this time.

     In the SAN Systems segment, the Company owns the manufacturing and
executive offices site in Wichita, Kansas.

     In addition, we maintain leased sales and engineering offices, regional
office space for our field sales, marketing and design center offices for both
our Semiconductor segment and our SAN Systems segment at various locations in
North America, Europe, Japan and elsewhere in Asia. We also maintain design
centers at various distributor locations. We also maintain leased executive
offices, design centers and sales offices in Bracknell, UK and Tokyo, Japan.
Leased facilities described above are subject to operating leases that expire in
2002 through 2011. (See Note 12 of Notes to Consolidated Financial Statements.)

     We have plans to acquire additional equipment for some of the above
facilities, but we believe that our existing facilities and equipment are well
maintained, in good operating condition, suitable for our operations and are
adequate to meet our current requirements.

ITEM 3.  LEGAL PROCEEDINGS

     In late 1995, a lawsuit was filed by certain former shareholders of our
Canadian subsidiary ("LSI Canada") in the Court of Queen's Bench of Alberta,
Judicial District of Calgary (the "Court") in which the question of LSI Canada's
value at September 7, 1995 is to be determined. At present, parties representing
approximately 580,000 shares are contesting the value of $4.00 (Canadian) that
was paid to the other former shareholders of LSI Canada at the time all shares
of LSI Canada not then owned by the Company were acquired by the Company.
Following a hearing held in March 2001, the Court dismissed the motion of the
former shareholders that challenged the proprietary of the fair value
proceedings initiated by LSI Canada and the jurisdiction of the Court to
adjudicate the matter. In addition, the Court ruled that the portions of the
application of the former shareholders to initiate a claim based upon
allegations that our actions and certain named (former) directors and a (former)
officer of LSI Canada were oppressive of the rights of minority shareholders of
LSI Canada were to be struck and the balance of the claims were stayed. The
Court also directed all of the litigants to recommence preparation for trial in
the fair value proceeding and advised the litigants of the Court's intention to
schedule a date for trial of that matter as soon as practicable. While we cannot
give any assurances regarding the resolution of these matters, we believe that
the final outcome will not have a material adverse effect on our consolidated
results of operations or financial condition. No assurance can be given,
however, that these matters will be resolved without our becoming obligated to
make payments

                                        20
<PAGE>

or to pay other costs to the opposing parties, with the potential for having an
adverse effect on our financial position or results of operations.

     In February 1999, a lawsuit alleging patent infringement was filed in the
United States District Court for the District of Arizona by the Lemelson
Medical, Education & Research Foundation, Limited Partnership against 88
electronics industry companies, including us. The case number is
CIV990377PHXRGS. The patents involved in this lawsuit are alleged to relate to
semiconductor manufacturing and computer imaging, including the use of bar
coding for automatic identification of articles. In September 1999, we filed an
answer denying infringement, raising affirmative defenses and asserting a
counterclaim for declaratory judgment of non-infringement, invalidity and
unenforceability of Lemelson's patents. In December 2001, the court held a
hearing on Cypress Semiconductor's and plaintiff's cross-motions for summary
judgment with respect to the 4,390,586 patent. In February 2002, the court
denied Cypress Semiconductor's motion for summary judgment. The court also
granted the plaintiff's cross motion in part with respect to Cypress
Semiconductor and denied the cross-motion with respect to all other defendants.
These activities are ongoing, and as yet, no trial date has been set. While we
cannot make any assurance regarding the eventual resolution of this matter, we
do not believe it will have a material adverse effect on our consolidated
results of operations or financial condition.

     U.S. Philips Corporation, a subsidiary of Royal Philips Electronics of
Netherlands, filed suits on October 17, 2001 in the U.S. District Court in New
York against eight companies, including us, for allegedly infringing and
inducing others to infringe Philips U.S. Patent Number 4,689,740. This patent is
directed to devices and methods used with the Inter-Integrated Circuit Bus.
While we cannot make any assurance regarding the eventual resolution of this
matter, we do not believe it will have a material adverse effect on our
consolidated results of operations or financial condition.

     The Company is a party to other litigation matters and claims that are
normal in the course of its operations, and while the results of such litigation
and claims cannot be predicted with certainty, the Company believes that the
final outcome of such matters is not expected to have a material adverse effect
on the Company's consolidated results of operations and financial position.

     At March 8, 2002, there were approximately 4,408 owners of record of our
common stock.

     We have never paid cash dividends on our common stock. It is presently our
policy to reinvest our earnings internally, and we do not anticipate paying any
cash dividends to stockholders in the foreseeable future.

</Table>

     The Company's fiscal years ended on December 31 in 2001, 2000, 1999, 1998
and 1997. During 2001, the Company recorded a $97 million in-process research
and development ("IPR&D") charge associated with the acquisitions of C-Cube and
AMI, which were effective on May 11, 2001 and August 31, 2001, respectively. In
addition, the Company recorded $220 million in restructuring of operations and
other non-recurring items, net and $105 million in amortization of non-cash
deferred stock compensation. (See Notes 2

                                        24

and 4 of the Notes to the Consolidated Financial Statements.) During 2000, the
Company recorded a $77 million IPR&D charge associated with the acquisitions of
ParaVoice, DataPath, IntraServer and the purchases of divisions of NeoMagic and
Cacheware. In addition, the Company recorded $41 million in non-cash deferred
stock compensation as a result of the adoption of FASB interpretation ("FIN")
No. 44, "Accounting for Certain Transactions Involving Stock Compensation,"
which was effective July 1, 2000. (See Note 2 of the Notes to the Consolidated
Financial Statements.) During 1999, the Company expensed an unamortized
preproduction balance of $92 million, net of taxes, associated with the
manufacturing facility in Gresham, Oregon and has presented it as a cumulative
effect of a change in accounting principle in accordance with SOP No. 98-5,
"Reporting on the Costs of Start-up Activities." (See Note 1 of the Notes to the
Consolidated Financial Statements.) During 1998, the Company reported a charge
for restructuring of operations and other non-recurring items, net of $75
million and a $146 million IPR&D charge related to the acquisition of Symbios on
August 6, 1998.

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

     We operate in an industry sector where stock values are highly volatile and
may be influenced by economic and other factors beyond our control. We believe
that our future operating results will continue to be subject to quarterly
variations based upon a wide variety of factors. See additional discussion
contained in "Risk Factors" set forth in Part I, Item 1 of this Annual Report on
Form 10-K for the year ended December 31, 2001, which is incorporated by
reference into this Part II, Item 7.

     Statements in this discussion and analysis include forward-looking
information within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities and Exchange Act of 1934, as amended.
These statements involve known and unknown risks and uncertainties. Our actual
results in future periods may be significantly different from any future
performance suggested in this report. Risks and uncertainties that may affect
our results may include, among others:

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

     - The current economic downturn;

     - Cyclical nature of both the Semiconductor and SAN Systems industries and
       the markets addressed by our products;

     - Availability and extent of utilization of manufacturing capacity;

     - Price erosion;

     - Competitive factors;

     - Timing of new product introductions;

     - Changes in product mix;

     - Fluctuations in manufacturing yields;

     - Product obsolescence;

     - Business and product market cycles;

     - Economic and technological risks associated with our acquisition and
       alliance activities; and

     - The ability to develop and implement new technologies.

     Our operating results could also be impacted by sudden fluctuations in
customer requirements, currency exchange rate fluctuations and other economic
conditions affecting customer demand and the cost of operations in one or more
of the global markets in which we do business. We operate in a technologically
advanced, rapidly changing and highly competitive environment. We predominantly
sell custom products to customers operating in a similar environment.
Accordingly, changes in the conditions of any of our customers may have a
greater impact on our operating results and financial condition than if we
predominantly offered standard products that could be sold to many purchasers.
While we cannot predict what effect these various factors may have on our
financial results, the aggregate effect of these and other factors could result
in significant volatility in our future performance. To the extent our
performance may not meet expectations published by external sources, public
reaction could result in a sudden and significantly adverse impact on the market
price of our securities, particularly on a short-term basis.

     We have international subsidiaries and distributors that operate and sell
our products globally. Further, we purchase a substantial portion of our raw
materials and manufacturing equipment from foreign suppliers and incur labor and
other operating costs in foreign currencies, particularly in our Japanese
manufacturing facilities. As a result, we are exposed to the risk of changes in
foreign currency exchange rates or declining economic conditions in these
countries. We utilize forward exchange and purchased currency option contracts
to manage our exposure associated with net asset and liability positions and
cash flows denominated in non-functional currencies. (See Note 6 of the Notes to
the Consolidated Financial Statements, hereafter referred

                                        26
<PAGE>

to as the Notes.) There is no assurance that these hedging transactions will
eliminate exposure to currency rate fluctuations that could affect our operating
results.

     Our corporate headquarters and some of our manufacturing facilities are
located near major earthquake faults. As a result, in the event of a major
earthquake, we could suffer damages that could significantly and adversely
affect our operating results and financial condition.

     Where more than one significant factor contributed to changes in results
from year to year, we have quantified material factors throughout the MD&A where
practicable.

     While management believes that the discussion and analysis in this report
is adequate for a fair presentation of the information, we recommend that you
read this discussion and analysis in conjunction with the remainder of this
Annual Report on Form 10-K.

CRITICAL ACCOUNTING POLICIES

     The discussion and analysis of our financial condition and results of
operations are based on the consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. Note 1 of the Notes describes the significant accounting policies
essential to the consolidated financial statements. The preparation of these
financial statements requires estimates and assumptions that affect the reported
amounts and disclosures.

     We believe the following to be critical accounting policies. That is, they
are both important to the portrayal of the Company's financial condition and
results, and they require critical management judgments and estimates about
matters that are inherently uncertain. Although we believe that our judgments
and estimates are appropriate and correct, actual future results may differ from
our estimates.

     Inventory reserves.  We establish reserves for estimated excess or obsolete
inventory based upon assumptions about demand and market conditions generally
over the following 12 months. We operate in a volatile industry sector
characterized by rapid changes in technology and market conditions.

     Valuation of long-lived and intangible assets and goodwill.  We operate our
own wafer fabrication facilities and make significant capital expenditures to
ensure that we are technologically competitive. In addition, we have actively
pursued the acquisition of businesses which have resulted in significant
goodwill and intangible assets. We assess the impairment of long-lived assets,
identifiable intangibles and related goodwill whenever events or changes in
circumstances indicate that the carrying value may not be recoverable. Factors
which we consider could trigger an impairment review include the following: (i)
significant negative industry or economic trends; (ii) exiting an activity in
conjunction with a restructuring of operations; (iii) current, historical or
projected losses that demonstrate continuing losses associated with an asset; or
(iv) a significant decline in our market capitalization relative to net book
value. When we determine that there is an indicator that the carrying value of
long-lived assets, identifiable intangibles and related goodwill may not be
recoverable, we measure impairment based on estimates of future cash flow. These
estimates include assumptions about future conditions within the Company and the
industry.

     Restructuring reserves.  We have recorded reserves for restructuring costs
related to the restructuring of operations. The restructuring costs include
payments to employees for severance, lease and contract termination fees,
decommissioning costs for fabrication equipment, and other costs to close
facilities. The reserves are recorded at the time we announce a plan to exit
certain activities and are based on estimates of the costs and length of time to
exit those activities.

     Income taxes.  We have recorded a valuation allowance to reduce the
deferred tax assets to the amount that is more likely than not to be realized.
We have considered future taxable income and ongoing prudent and feasible tax
planning strategies in assessing the need for the valuation allowance.

OVERVIEW

     Revenues decreased 35% to $1.78 billion in 2001 from $2.74 billion in 2000.
The decrease was primarily the result of decreased demand, most notably for
products used in broadband access, networking infrastructure, storage
infrastructure applications, and storage area network ("SAN") systems,
reflecting the economic downturn in the industry. The decline in revenues was
partially offset by the additional revenues from acquisitions of C-Cube
Microsystems, Inc. ("C-Cube") and the RAID division of American Megatrends, Inc.
("AMI") in 2001.

     Gross profit margin decreased to 23% in 2001 from 43% in 2000 primarily as
a result of decreased revenue for higher margin products, higher manufacturing
variances and period costs as a percentage of revenues and additional excess
inventory and related charges of $210.6 million for 2001 as compared to $11.1
million in 2000. The decrease in gross profit margin was offset in part by
cost-saving measures undertaken during 2001 discussed further in Note 4 of the
Notes. Operating expenses increased 61% to $1.4 billion in 2001 from $880
million in 2000. The increase was primarily a result of the operating expenses
of C-Cube and AMI, a $219.6 million charge for restructuring and other
non-recurring items, net, and other acquisition-related charges of $96.6 million
for in-process research and development ("IPR&D"), $104.6 million for
amortization of non-cash deferred stock compensation and $188.3 million in
amortization of intangibles. (See Notes 2 and 4 of the Notes.) Research and
development ("R&D") costs increased by $124.2 million in 2001 due to additional
costs incurred in connection with acquisitions in 2001 and continued core
business spending, which was offset in part by cost-saving measures undertaken
during the year. Selling, general and administrative ("SG&A") costs remained
relatively flat from year to year. Incremental, post-acquisition SG&A expenses
of C-Cube and AMI were largely offset by cost-saving measures undertaken during
the year. For the years ended December 31, 2001 and 2000, gains on sale of
investments in equity securities were $5.3 million and $80.1 million,
respectively. For the year ended December 31, 2001, we recorded a net loss of
$992.0 million, or $2.84 loss per diluted share, compared to net income for the
same period in 2000 of $236.6 million, or $0.70 income per diluted share. A
further discussion on results of operations is covered below.

     Cash and short-term investments decreased by 11% to $1.01 billion as of
December 31, 2001 from $1.13 billion as of December 31, 2000. The decrease is
primarily attributable to lower cash flows from our continuing operations. Some
of the major transactions that impacted cash and short-term investments during
the year were as follows:

     - Payments for acquisitions made in 2001.

     - In the third quarter of 2001, we amended the master lease and security
       agreements entered into in April 2001 and March 2000. (See Note 12 of the
       Notes.) Pursuant to the amendments, we participated as a debt holder in
       the lease transactions replacing some of the existing banks. As of
       December 31, 2001, our debt contribution of $242 million was recorded as
       non-current assets on the balance sheet. We cash collateralized $54
       million of the remaining debt and equity investments of the lessors. This
       was also recorded as non-current assets and deposits.

     - On October 30, 2001, we issued $490 million of 4% Convertible
       Subordinated Notes due in 2006, increasing our long term liabilities to
       $1.5 billion at December 31, 2001 from $936.1 million at December 31,
       2000. (See Note 8 of the Notes.)

     Our significant cash position provides us with the capital to make
strategic acquisitions and to continue investing in key technologies.

     Stock split.  On January 25, 2000, we announced a two-for-one common stock
split, which was declared by the Board of Directors as a 100% stock dividend
payable to stockholders of record on February 4, 2000 as one new share of common
stock for each share held on that date. The newly issued common stock shares
were distributed on February 16, 2000. In the following discussion and analysis,
stockholders' equity has been restated to give retroactive recognition to the
two-for-one common stock split announced on January 25, 2000 for all periods
presented by reclassifying the par value of the newly issued shares arising from
the split from additional paid-in capital to common stock. In addition, all
references in the financial statements to number of shares, per share amounts,
stock option data and market prices of our common stock have been restated.

     Acquisitions and other major transactions.  We are continually exploring
strategic acquisitions that build upon our existing library of intellectual
property and increase our leadership position in the markets where we operate.

  2001

     During 2001, we acquired C-Cube Microsystems Inc. and certain tangible and
intangible assets associated with the Redundant Array of Independent Disks, or

     On April 4, 2001, we announced a co-development and foundry supply
agreement with Taiwan Semiconductor Manufacturing Company Ltd. ("TSMC"). This
agreement is part of our strategy to "outsource," that is to procure a larger
portion of our wafer requirements from external sources. As a result of our
joint development efforts with TSMC we anticipate purchasing, consistent with
our "outsourcing" strategy, such portion of our wafer volume requirements based
on the 0.13-micron process technology that we do not manufacture ourselves. In
addition, we anticipate being able to defer the need to expand our manufacturing
capacity for the 0.13-micron technology beyond the time when products designed
for that technology would begin volume production. We also anticipate
collaborating with TSMC on further advancement in wafer fabrication technology.

  2000

     During 2000, we acquired a division of NeoMagic Corporation ("NeoMagic"), a
division of Cacheware, Inc. ("Cacheware"), Intraserver Technology, Inc.
("Intraserver"), DataPath Systems, Inc. ("DataPath"), ParaVoice Technologies,
Inc. ("ParaVoice") and Syntax Systems, Inc. ("Syntax"). The acquisitions were
accounted for as purchases and accordingly, the estimated fair value of assets
acquired and liabilities assumed and the results of operations were included in
our consolidated financial statements as of the effective date of each
acquisition through the end of the period. These transactions are summarized
below. There were no significant differences between the accounting policies of
LSI and the companies acquired. (See Note 2 of the Notes.)

  1999

     On June 22, 1999, we combined with SEEQ Technology, Inc. ("SEEQ") in a
transaction accounted for as a pooling of interests. All financial information
has been restated retroactively to reflect the combined operations of LSI Logic
and SEEQ as if the combination has occurred at the beginning of the earliest
period presented. (See Note 2 of the Notes.)

RESULTS OF OPERATIONS

     Revenue.  Total revenues decreased 35% to $1.78 billion in 2001 from $2.74
billion in 2000. Revenues for the Semiconductor segment decreased 33% to $1.57
billion in 2001 from $2.34 billion in 2000. The decrease was primarily
attributable to decreased demand, most notably for products used in broadband
access, networking infrastructure and storage infrastructure applications,
reflecting the economic downturn in the semiconductor industry. The decline in
revenues in this sector was offset partially by the additional revenues from
C-Cube and AMI. Revenues for the SAN Systems segment decreased 47% to $211.3
million in 2001 from $399.1 million in 2000 due to decreased demand reflecting
industry declines for all products sold in the SAN Systems segment. As the
economic trends reverse, we expect to see sequential quarterly growth in
revenues of up to 3% in the first quarter of 2002 from the $406 million in the
fourth quarter of 2001.

     Total revenues increased 31% to $2.74 billion in 2000 from $2.09 billion in
1999. Revenues for the Semiconductor segment increased 29% to $2.34 billion in
2000 from $1.81 billion in 1999. Significant factors that contributed to this
revenue growth included increased demand for semiconductor products used in
broadband communications, networking infrastructure and storage infrastructure
applications, particularly in broadband access and networks, and storage
components. Revenues for the SAN Systems segment increased 43% to $399.1 million
in 2000 from $279.3 million in 1999. The increase was attributable to growth in
demand for all products used in the SAN Systems segment.

     One customer represented 18% of our total consolidated revenues for the
year ended December 31, 2001 and another customer represented 12% and 11% of our
total consolidated revenues for each of the years ended December 31, 2000 and
1999, respectively. One customer represented 21% of total revenues in the
Semiconductor segment for the year ended December 31, 2001. During 2000, no
customer represented 10% or more of total revenues in the Semiconductor segment.
During 1999, one customer represented 10% of total Semiconductor revenues. In
the SAN Systems segment, there were two customers with revenues representing 21%
each, and one customer representing 13% of total SAN Systems revenues for the
year ended December 31, 2001. During 2000, there were three customers with
revenues representing 31%, 17% and 13% of total SAN Systems revenues. During
1999, there were three customers with revenues representing 29%, 27% and 14% of
SAN Systems revenues.

     Revenues from domestic operations were $880.8 million, representing 49% of
consolidated revenues for 2001, as compared to $1.7 billion and $1.2 billion for
2000 and 1999, representing 61% and 58% of consolidated revenues, respectively.
The decline in domestic revenues is mainly due to the severity of the economic
downturn in the U.S. as compared to Pan Asia and Japan.

     Operating costs and expenses.  Key elements of the consolidated statements
of operations, expressed as a percentage of revenues for the respective segment,
were as follows:

     Gross profit margin.  We have advanced wafer manufacturing operations in
Oregon and Japan. We also acquire wafers from foundries in other locations. This
allows us to maintain our ability to provide products to customers with minimal
disruption in the manufacturing process due to economic and geographic risks
associated with each geographic location.

     The gross profit margin percentage for 2001 decreased to 23% from 43% in
2000 on a consolidated basis, reflecting lower gross profit margins in both of
our segments. The gross profit margin percentage for the Semiconductor segment
was 22% in 2001 compared to 44% in 2000. The decrease in the semiconductor
segment primarily reflect the economic downturn as evidenced by:

     - Decreased revenue for higher margin products;

     - Higher manufacturing variances and period costs as a percentage of
       revenues;

     - Additional excess inventory and related charges of $204.6 million in
       2001.

     The additional excess inventory and related charges were primarily
associated with underutilization charges related to a temporary idling of our
fabrication facilities, coupled with inventory production in anticipation of the
closing of our Colorado Springs fabrication facility (see Note 4 of the Notes)
and a sudden and significant decrease in forecasted revenue, and was calculated
in accordance with our policy, which is primarily based on inventory levels in
excess of 12-month judged demand for each specific product.

     The gross profit margin percentage for the SAN Systems segment was 30% in
2001 compared to 38% in 2000. The decrease is primarily attributable to
decreased revenue for higher margin products and additional excess inventory and
related charges of approximately $6 million recorded during 2001.

     The gross profit margin percentage for 2000 increased to 43% from 38% in
1999 on a consolidated basis, reflecting improved gross profit margins in both
of our segments. The gross profit margin percentage for the Semiconductor
segment was 44% in 2000 compared to 39% in 1999. The increase primarily
reflected a combination of the following factors:

     - Increased production capacity utilization at our fabrication facility in
       Gresham, Oregon, which commenced operations in December 1998, and

     - Increased revenue from higher margin products used in broadband
       communications and storage infrastructure applications.

                                        31
<PAGE>

     The increase in gross profit margin in 2000 as compared to 1999 was offset
in part by the following factors:

     - $11.1 million non-recurring charge associated with the elimination of a
       non-strategic product area, and

     - An increase in compensation-related expenses.

     The gross profit margin percentage for the SAN Systems segment was 38% in
2000 compared to 33% in 1999. The increase is primarily attributable to changes
in product mix to include newer generation products, which have higher margins
than other SAN business products.

     Our operating environment, combined with the resources required to operate
in the semiconductor industry, requires that we manage a variety of factors.
These factors include, among other things:

     - Product mix;

     - Factory capacity and utilization;

     - Manufacturing yields;

     - Availability of certain raw materials;

     - Terms negotiated with third-party subcontractors; and

     - Foreign currency fluctuations.

     These and other factors could have a significant effect on our gross profit
margin in future periods.

     Changes in the relative strength of the yen may have a greater impact on
our gross profit margin than other foreign exchange fluctuations due to our
wafer fabrication operations in Japan. Although the yen weakened (the average
yen exchange rate for 2001 depreciated 14% from 2000), the effect on gross
profit margin and net income was not significant because yen-denominated sales
offset a substantial portion of yen-denominated costs during the period.
Moreover, we hedged a portion of our remaining yen exposure. (See Note 6 of the
Notes.) Future changes in the relative strength of the yen or mix of foreign
currency denominated revenues and costs could have a significant effect on our
gross profit margin or operating results.

     Research and development.  R&D expenses increased 33% to $503.1 million
during 2001 as compared to $378.9 million in 2000 on a consolidated basis. R&D
expenses for the Semiconductor segment increased 35% to $473.1 million in 2001
from $351.7 million in 2000. The increase was attributable to the following
factors:

     - Increased R&D activities based on new R&D projects, including those
       acquired in business combinations in 2001 (see Note 2 of the Notes);

     - Expenditures related to the continued development of advanced sub-micron
       products and process technologies.

     The increase was offset in part by $20.0 million and $24.0 million of
research and development benefits associated with a technology transfer
agreement entered into with Silterra in Malaysia during 2001 and 2000,
respectively. (See Note 3 of the Notes.) We will record an additional $4.0
million credit to R&D over the remaining contract term of less than one year for
technology to be transferred to Silterra.

     R&D expenses for the SAN Systems segment increased 10% to $30.0 million in
2001 from $27.2 million in 2000. The increase is primarily attributable to
higher compensation-related expenses due to an increase in average headcount
during the periods presented.

     R&D increased 27% to $378.9 million during 2000 as compared to $297.6
million in 1999. R&D expenses for the Semiconductor segment increased 29% to
$351.7 million in 2000 from $271.8 million in 1999. The increase was
attributable to the following factors:

     - Increased R&D activities based on the acquisitions of companies during
       2000 (see Note 2 of the Notes);

                                        32
<PAGE>

     - Expenditures related to the continued development of advanced sub-micron
       products and process technologies; and

     - Increased compensation costs during 2000.

     The increase was offset in part by $24.0 million and $15.0 million of
research and development benefits associated with a technology transfer
agreement entered into with Silterra in Malaysia during 2000 and 1999,
respectively. (See Note 3 of the Notes.)

     R&D expenses for the SAN Systems segment increased 6% to $27.2 million in
2000 from $25.7 million in 1999. The increase is primarily attributable to
increased compensation expenses.

     As a percentage of revenues, R&D expenses were 28% in 2001, and 14% in 2000
and 1999, respectively, on a consolidated basis. R&D expenses as a percentage of
revenues for the Semiconductor segment were 30% in 2001 and 15% in 2000 and
1999, respectively. R&D expenses as a percentage of revenues for the SAN Systems
segment were 14% in 2001, 7% in 2000 and 9% in 1999. The increase in R&D
expenses as a percentage of revenues for both segments is primarily a result of
lower revenues for the periods presented and the effects of R&D spending changes
as discussed above.

     Selling, general and administrative.  SG&A expenses were flat at $307.3
million in 2001 as compared to $307.0 million in 2000 on a consolidated basis.
SG&A expenses for the Semiconductor segment decreased 5% to $241.5 million in
2001 from $255.2 million in 2000. SG&A expenses for the SAN Systems segment
increased 27% to $65.8 million in 2001 from $51.8 million in 2000. SG&A expenses
on a consolidated basis in 2001 were impacted primarily by the following
factors:

     - Continued SG&A expenses for the former C-Cube and AMI RAID business,
       which are part of the Semiconductor segment and included in our
       consolidated financial statements as of May 11, 2001 and August 31, 2001,
       respectively; and

     - An increase in compensation-related expenses for the SAN Systems segment
       due to an increase in average headcount during 2001.

     The above increases were offset in part by the positive effects of various
cost reduction programs in both segments in 2001. These include, among other
things, a reduction in workforce, elimination of 2001 annual merit increases and
bonus payments, and shutdowns of operations during the year. (See Note 4 of the
Notes.)

     SG&A expenses increased 19% to $307.0 million in 2000 as compared to $257.7
million in 1999. SG&A expenses for the Semiconductor segment increased 13% to
$255.2 million in 2000 from $225.8 million in 1999. The increase was primarily
attributable to sales commissions on increased revenues and increased
compensation costs based on an increase in headcount in 2000. SG&A expenses for
the SAN Systems segment increased 62% to $51.8 million in 2000 from $32.0
million in 1999. The increase in SG&A expenses was primarily attributable to an
increase in compensation costs based on an increase in headcount in 2000 and
also an increase in commission related expenses for sales personnel based on the
increased revenues during 2000.

     As a percentage of revenues, SG&A expenses increased to 17% in 2001 from
11% in 2000 and 12% in 1999 on a consolidated basis. SG&A expenses as a
percentage of revenues for the Semiconductor segment were 15% in 2001, 11% in
2000 and 12% in 1999. SG&A expenses as a percentage of revenues for the SAN
Systems segment were 31% in 2001, 13% in 2000 and 11% in 1999. The increase in
SG&A expenses as a percentage of revenues for both segments is primarily a
result of lower revenues for the periods presented and the effects of SG&A
spending changes as discussed above.

     Acquired in-process research and development.  During 2001, we recorded a
$96.6 million IPR&D charge associated with the acquisitions of C-Cube and the
purchase of the RAID business of AMI. During 2000, we recorded a $77.4 million
IPR&D charge associated with the acquisitions of ParaVoice, DataPath,
Intraserver and the purchase of divisions of NeoMagic and Cacheware. There was
no IPR&D charge recorded

                                        33

</Table>

     The above noted acquisitions were all accounted for as purchases and the
estimated fair value of net assets or liabilities acquired and the results of
operations were included in our consolidated financial statements as of the
acquisition date through the end of the period. (See Note 2 of the Notes.)

     The amounts of IPR&D were determined by identifying research projects for
which technological feasibility had not been established and no alternative
future uses existed as of the respective acquisition dates. The value of the
projects identified to be in progress was determined by estimating the future
cash flows from the projects once commercially feasible, discounting the net
cash flows back to their present value and then applying a percentage of
completion to the calculated value. The net cash flows from the identified
projects were based on estimates of revenues, cost of revenues, research and
development costs, selling general and administrative costs and applicable
income taxes for the projects. Total revenues for the projects are expected to
extend through the dates noted in the above table by acquisition. These
projections were based on estimates of market size and growth, expected trends
in technology and the expected timing of new product introductions by our
competitors and us. These estimates do not account for any potential synergies
that may be realized as a result of the acquisition and are in line with
industry averages and growth estimates.

  PERCENTAGE OF COMPLETION

     The percentage of completion for the projects for the purchases of the RAID
business from AMI, C-Cube, ParaVoice, Cacheware and a division of Neomagic were
determined based on research and development expenses incurred as of the
acquisition dates for the projects as a percentage of total research and
development expenses to bring the projects to technological feasibility.

     The percentage of completion for the projects for the purchases of
Intraserver, DataPath and ZSP were determined using milestones representing
management's estimate of effort, value added and degree of difficulty of the
portion of the projects completed as of the acquisition dates, as compared to
the remaining research and development to be completed to bring the projects to
technological feasibility. The development process is grouped into three phases,
with each phase containing between one and five milestones. The three phases
are:

     - Researching the market requirements and the engineering architecture and
       feasibility studies;

     - Design and verification milestones; and

     - Prototyping and testing the product (both internal and customer testing).

  DISCOUNT AND ROYALTY RATES

     The discount rate is used for the projects to account for the risks
associated with the inherent uncertainties surrounding the successful
development of the IPR&D, market acceptance of the technology, the useful life
of the technology, the profitability level of such technology and the
uncertainty of technological advances, which could impact the estimates
described above. We applied a royalty rate by project by acquisition to
operating income to attribute value for dependency on predecessor core
technologies. See details in table above.

  PROJECT DESCRIPTIONS AND ESTIMATES OF COMPLETION BY ACQUISITION

     RAID business.  On August 31, 2001, we entered into an Asset Purchase
Agreement with AMI. Under the agreement, we acquired certain tangible and
intangible assets associated with AMI's RAID business. The acquisition will
enhance product offerings and is included in the Semiconductor segment. As of
the acquisition date, there were several projects in-process. The projects were
for development of RAID technology applications. Development of these projects
started in early 2000 and 2001. As of August 31, 2001, we estimated the projects
were approximately 12% to 62% complete for the RAID projects and the cost to
complete these projects was estimated at $4.6 million for 2001 and $2.4 million
for 2002. As of December 31, 2001, the actual development timeline and costs are
in line with estimates.

     C-Cube.  On March 26, 2001, we signed a definitive merger agreement to
acquire C-Cube Microsystems Inc. The acquisition is intended to enhance and
accelerate our DVD product offerings in the Semiconductor segment. As of the
acquisition date, there were various projects that were in-process. The majority
of the projects identified consist of Digital Video Disc Player ("DVD"), DVD
Recorder ("DVD-R"), Consumer Set-Top Box and Cable Modem. Development of these
projects started in early 1999. As of May 11, 2001, we estimated the projects
were approximately 84%, 62%, 61% and 69% complete for DVD, DVD-R, Consumer
Set-Top Box and Cable Modem, respectively. As of the acquisition date, the cost
to complete these projects was estimated at $22.7 million in 2001 and $9.1
million in 2002. As of December 31, 2001, the actual development timeline and
costs are in line with estimates.

     ParaVoice.  On October 23, 2000, we entered into an Asset Acquisition
Agreement with ParaVoice. Under the agreement, we acquired certain tangible and
intangible assets associated with ParaVoice's Voice over Internet Protocol
("VoIP") and Voice over DSL ("VoDSL") technology. The acquisition is intended to
enhance product offerings in the Semiconductor segment. As of the acquisition
date, there was one project in-process for the development of ParaVoice's VoIP
products, which was started in late 1999. As of October 23, 2000, we estimated
that the project was 23% complete. As of the acquisition date, the cost to
complete the project was estimated at $6.3 million in 2001 and $7.3 million for
2002. As of December 31, 2001, the actual development timeline and costs are in
line with estimates.

     DataPath.  On July 14, 2000, we acquired DataPath, a privately held
supplier of communications chips for broadband, data networking and wireless
applications, pursuant to the terms of the Agreement and Plan of Reorganization
and Merger. The acquisition of DataPath is expected to enhance our product
offerings in the communications market in the Semiconductor segment. As of the
acquisition date, there were various projects in-process. The majority of the
projects identified consist of Read Channel, Asynchronous Digital Subscriber
Line ("ADSL") and Tuner technologies. As of July 14, 2000, we estimated the
projects were approximately 50%, 65% and 75% complete in aggregate for Read
Channel, ADSL and Tuner Technologies, respectively. As of the acquisition date,
the cost to complete the projects was estimated at $8.3 million and $2.8 million
for ADSL and Tuner projects, respectively, through early 2002 and $32.8 million
for Read Channel projects through 2004. As of December 31, 2001, the actual
development timeline and costs are in line with estimates for continuing
projects.

     Intraserver.  On May 26, 2000, we acquired Intraserver pursuant to the
terms of the Agreement and Plan of Reorganization and Merger. The acquisition of
Intraserver is expected to enhance our host adapter board and other product
offerings in the storage infrastructure and communications markets in the
Semiconductor segment. As of the acquisition date, there were various projects
in-process. The majority of the projects identified are targeted to high-end
data storage and communication devices, where input/output

                                        35
<PAGE>

functionality and speed is critical. As of May 26, 2000, we estimated the
projects were 58% complete in aggregate (ranging from 20% to 95%). As of the
acquisition date, the costs to complete the project were $0.5 million in 2000
and early 2001. As of December 31, 2001, the project was complete.

     Division of Cacheware.  On April 27, 2000, we entered into an Asset
Purchase Agreement with Cacheware. Under the agreement, we acquired certain
tangible and intangible assets associated with Cacheware's storage area network
business. ("SAN Business"). The acquisition was intended to provide a key
technology to enhance our SAN solutions. The SAN Business is included in our SAN
Systems segment. The project in-process as of their acquisition date was for
development of a SAN appliance. Development of the SAN appliance was started in
January 1999. As of April 27, 2000, we estimated that the project was 90%
complete and that remaining costs to complete the project would be $0.4 million
in 2000 and early 2001. As of December 31, 2001, the project is scheduled to be
completed in the first quarter of 2002.

     Division of NeoMagic.  On April 13, 2000, we entered into an Asset Purchase
Agreement with NeoMagic. Under the Agreement, we acquired certain tangible and
intangible assets from NeoMagic, which includes NeoMagic's optical read-channel
mixed-signal design team and RF intellectual property. The acquisition was
intended to enhance and accelerate our set-top decoder product offerings in the
Semiconductor segment. As of the acquisition date, one project was identified to
be in-process. The project was for the development of a two-chip controller
chipset. As of April 13, 2000, we estimated that the project was 68% complete.
As of the acquisition date, the project costs were estimated at $3.0 million for
the remainder of 2000 and $4.0 million in 2001. In the second quarter of 2001,
the project was abandoned and remaining intangibles and goodwill were written
off. See discussion under restructuring of operations and other non-recurring
items.

     ZSP.  On April 14, 1999, we acquired all of the outstanding capital stock
of ZSP, a development stage semiconductor company involved in the design and
marketing of programmable Digital Signal Processors ("DSPs") for use in wired
and wireless communications. We acquired ZSP's in-process DSP research and
development project in process that was targeted at the telecommunications
market. The project was completed in 1999.

     Development of the above-noted technologies that have not yet been
completed remains a significant risk to us due to the remaining effort to
achieve technological feasibility, rapidly changing customer markets and
significant competitive threats from numerous companies. Failure to bring the
product to market in a timely manner could adversely affect our sales and
profitability in the future. Additionally, the value of other intangible assets
acquired may become impaired.

     Restructuring of operations and other non-recurring items.  We recorded
approximately $219.6 million in restructuring and non-recurring charges for the
year ended December 31, 2001, consisting of $207.2 for restructuring of
operations and $12.4 million for other non-recurring charges.

  RESTRUCTURING

     In September 2001, we announced the consolidation of U.S. manufacturing
operations at Gresham, Oregon and the transfer of process research and
development from Santa Clara, California to Gresham, Oregon. We also announced
the closure of certain assembly activities in Fremont, California, which will be
transferred offshore. In September 2001, we recorded a restructuring charge of
$77 million for fixed asset write-downs due to impairment in the U.S., losses on
termination of operating leases for equipment and facilities, severance for
approximately 600 employees across multiple company activities and functions in
the U.S., Europe, Japan and Asia Pacific as well as other exit costs. In
December 2001, we recorded $14 million of additional fixed asset write-downs due
to impairment for the Santa Clara facility. We reclassified $25 million,
representing the fair market value of the assets identified above, from
property, plant and equipment to other current assets during the year to reflect
the intention to dispose of the assets within 12 months. In addition, in
December 2001, approximately $4 million in exit costs for the closures of the
Santa Clara facility was recorded relating primarily to labor and facilities
charges.

     In April 2001, we announced the closure of our Colorado Springs fabrication
facility ("the facility") in August 2001. In May 2001, we entered into a
definitive agreement to sell the facility to a third party. As part

                                        36
<PAGE>

of the agreement, we agreed to purchase a minimum amount of production wafers
and die from the facility for a period of 18 months following the close of the
transaction. During the quarter ended June 30, 2001, we recorded an impairment
charge of $71 million relating to the facility, of which approximately $35
million was recorded in cost of sales and $36 million was recorded in
restructuring charges. The restructuring charges consisted of fixed asset
write-downs due to impairment, losses on termination of operating leases for
equipment, severance for approximately 413 manufacturing employees and other
exit costs. On August 1, 2001, we announced the termination of the agreement to
sell the facility. In September 2001, we recorded an additional restructuring
charge of $55 million for fixed asset write-downs and other exit costs
associated with the planned closure of the facility. The additional asset
write-downs during the third quarter of 2001 were incurred to reflect the new
value of the facility's assets if sold on a piecemeal basis rather than sold as
a facility in continued use. In addition, equipment market values continued to
decline in the third quarter of 2001. We reclassified approximately $62 million
from property, plant and equipment to other current assets to reflect the
intention to dispose of the facility within the next twelve months. The facility
was closed in the fourth quarter of 2001. In December 2001, we recorded $1.5
million of additional fixed asset write-downs due to impairment for the Colorado
Springs facility. In addition, approximately $3 million in exit costs for the
closure of the Colorado Springs facilities were recorded relating primarily to
labor and facilities charges.

     We recorded approximately $16 million in restructuring charges in the
second quarter of 2001 primarily associated with the write-down of fixed assets
due to impairment in the U.S., Japan and Hong Kong that will be disposed of, and
severance charges for approximately 240 employees across multiple company
activities and functions in the U.S., Europe and Asia Pacific. As a result of
the continued decline in the equipment market during the third quarter of 2001,
we recorded an additional charge of $0.5 million during the third quarter of
2001 to reflect the fair value of the equipment when sold. In December 2001, we
recorded $0.3 million of additional fixed asset write-downs due to impairment in
Japan. We plan to sell the assets and accordingly have reclassified $2 million
from property, plant and equipment to assets held for sale to reflect the
intention to sell the assets within the next 12 months.

     The fair value of assets determined to be impaired was the result of
independent appraisals and the use of management estimates. Given that current
market conditions for the sale of older fabrication facilities and related
equipment may continue to deteriorate, there can be no assurance that we will
realize its current net book value for the assets. We will reassess the
realizability of the carrying value of these assets at the end of each quarter
until the assets are sold or otherwise disposed of and additional adjustments
may be necessary.

     On January 16, 2002, the Company announced a series of actions to reduce
costs and tailor company expenses to current revenues. These actions include:
restructuring the Company's manufacturing operations in Tsukuba, Japan;
divesting the CDMA handset and DSL standard product business units and reducing
the worldwide workforce by approximately 1,400 positions or 20 percent. As a
result of the restructuring actions taken during 2002, we expect to reduce
expenses by approximately $120 million in 2002. (See Note 13 of the Notes.)

     The following table sets forth our restructuring reserves as of December
31, 2001:

(a) Amounts utilized in 2001 reflect a non-cash write-down of fixed assets in
    the U.S., Japan and Hong Kong due to impairment of $133.8 million and cash
    payments for machinery and equipment decommissioning costs of $2.2 million.
    The fixed asset write-downs were accounted for as a reduction of the assets
    and did

                                        37
<PAGE>

    not result in a liability. The $3.8 million balance as of December 31, 2001
    relates to machinery and equipment decommissioning costs in the U.S.

(b) Amounts utilized represent cash payments related to the severance of
    approximately 1180 employees during the year ended December 31, 2001. The
    $0.7 million balance as of December 31, 2001 will be paid during the first
    six months of 2002.

(c)  Amounts utilized represent cash payments.

  OTHER NON-RECURRING ITEMS:

     We recorded approximately $12.4 million in other non-recurring charges
during 2001 as follows:

     - $8.1 million in charges associated with the write-down of intangible
       assets due to impairment. The majority of the intangible assets were
       originally acquired in the purchase of a division of NeoMagic in the
       second quarter of 2000.

     - $4.3 million in charges primarily consisting of the write-down of an
       investment in a marketable equity security and related purchased
       intellectual property.

  2000 AND 1999

     We recorded restructuring of operations and other non-recurring net charges
of $2.8 million in 2000. This was primarily related to the loss on an agreement
entered into with a third party to outsource certain testing services previously
performed by us at our Fremont, California facility. (See Note 4 of the Notes.)

     We recorded restructuring of operations and other non-recurring net
benefits of $2.1 million in 1999. The net benefit reflected the combination of
the following:

     - Approximately $2.9 million in restructuring charges and $5.5 million in
       merger-related expenses in connection with the merger with SEEQ on June
       22, 1999 (see Note 2 of the Notes.) The restructuring charge was
       primarily comprised of write-downs of fixed assets that were duplicative
       to the combined company, charges for exit costs relating to
       non-cancelable building lease contracts and severance costs. The
       restructuring actions as outlined by the restructuring plan were
       completed by June 30, 2000, one year from the date the reserve was taken.

     - Approximately $10.5 million of 1998 restructuring reserve reversals
       associated with a change in management estimate. (See Note 4 of the
       Notes.) The amount consisted of the following:

       - $3.9 million of reserves for lease termination and non-cancelable
         purchase commitments primarily in the U.S. and Europe;

       - $3.7 million of excess severance reserves in the U.S., Japan, and
         Europe;

       - $2.0 million of reserves for manufacturing facility decommissioning
         costs and other exit costs primarily in the U.S. and Japan; and

       - $0.9 million of related cumulative translation adjustments.

     The change in management estimates of the reserve requirements stemmed
primarily from the following factors:

     - A significant increase in the requirement for manufacturing capacity to
       meet expected sales growth, which resulted in retention of certain
       employees originally targeted for termination of employment and in
       reversal of the reserve for decommissioning costs as a result of
       retention of the U.S. and Japan operations facilities originally targeted
       for sale; and

     - Our ability to exit lease commitments and non-cancelable purchase
       commitments more favorably than originally anticipated in the U.S. and
       Europe.

     Amortization of intangibles.  Amortization of goodwill and other
intangibles increased to $188.3 million in 2001 from $72.6 million in 2000. The
increase was primarily related to additional amortization of goodwill and other
intangibles associated with the acquisitions of C-Cube and the RAID business
from AMI. (See Note 2 of the Notes.)

                                        38
<PAGE>

     Amortization of goodwill and other intangibles increased to $72.6 million
in 2000 from $46.6 million in 1999. The increase was primarily related to
additional amortization of goodwill associated with the acquisitions of Syntax,
ParaVoice, DataPath, Intraserver and the acquisition of divisions of Cacheware
and NeoMagic.

     In July 2001, the Financial Accounting Standards Board ("FASB") issued FASB
Statements Nos. 141 and 142 (SFAS 141 and SFAS 142), "Business Combinations" and
"Goodwill and Other Intangible Assets." The statements were effective for our
purchase of the RAID business from AMI, which closed on August 31, 2001. As a
result of the application of SFAS 141 and 142, approximately $129 million of
goodwill related to the AMI acquisition will not be amortized. See Note 2 of the
Notes and the recent accounting pronouncements section below for further
discussion.

     Amortization of non-cash deferred stock compensation.  Amortization of
non-cash deferred stock compensation of $104.6 million and $41.1 million in 2001
and 2000, respectively is due to non-cash deferred stock compensation recorded
in connection with acquisitions after July 1, 2000. Acquisitions consisted of
C-Cube and the RAID business from AMI in 2001 and DataPath and Syntax in 2000
for which deferred stock compensation and related amortization were recorded. We
amortize deferred stock compensation ratably over the vesting period. At
December 31, 2001, the deferred stock compensation that remained was $124.1
million and it is expected to be amortized over the next four years. (See Note 2
to the Notes.)

     Interest expense.  Interest expense increased to $44.6 million in 2001 from
$41.6 million in 2000. The increase was primarily attributable to increased debt
outstanding due to the issuance of the $490.0 million of 4% Convertible
Subordinated Notes (the "2001 Convertible Notes") in October 2001. (See Note 8
of the Notes.)

     Interest expense increased to $41.6 million in 2000 from $40.0 million in
1999. The increase was primarily attributable to increased debt outstanding due
to the issuance of $500.0 million of 4% Convertible Subordinated Notes (the
"2000 Convertible Notes") in February 2000. (See Note 8 of the Notes.)

     Interest income and other.  Interest income and other decreased to $14.5
million in income in 2001 from $51.8 million in income in 2000. The decrease was
primarily attributable to the following events in 2001, which were absent in
2000:

     - $15.2 million write-down of equity investments due to impairment
       considered to be other than temporary, net of a $3.8 million pre-tax gain
       associated with equity securities of a certain technology company that
       was acquired by another technology company (See Note 5 of the Notes);

     - $8.9 million of lower interest income due to lower average balances of
       interest-generating cash, cash equivalents and short-term investments and
       lower interest rates in 2001;

     - The write-off of debt issuance costs of approximately $3.5 million
       associated with the repayment of bank debt and a master lease and
       security agreement (See Notes 8 and 12 of the Notes); and

     - The cost of purchased option contracts, bank fees and other miscellaneous
       expenses.

     In addition, the $5.7 million pre-tax gain in 2000 discussed below was
absent in 2001.

     Interest income and other increased to $51.8 million in income in 2000 from
$17.6 million in income in 1999. The increase was primarily attributable to the
following events in 2000, which were absent in 1999:

     - $5.7 million pre-tax gain on the sale of a U.S. facility in Fremont,
       California, and

     - $33.8 million of additional interest income due to higher average
       balances of interest-generating cash, cash equivalents and short-term
       investments and higher interest rates.

     The above-noted increase was offset in part by net losses on disposals of
fixed assets, bank fees and other miscellaneous expenses during 2000.

     Gain on sale of equity securities.  During 2001, we sold investments in
certain marketable equity securities for $7.9 million in the open market,
realizing a pre-tax gain of approximately $5.3 million. During 2000, we sold
investments in certain marketable equity securities for $78.8 million in the
open market,

                                        39
<PAGE>

realizing a pre-tax gain of approximately $73.3 million. In 2000, we also
recognized a $6.8 million pre-tax gain associated with equity securities of a
certain technology company that was acquired by another technology company. In
1999, we recognized a gain of $48.4 million on proceeds of $49.4 million from
the sale of marketable securities.

     Provision for income taxes.  In 2001, we recorded an income tax benefit of
$39.2 million, which represents an effective tax rate of 4%. This rate differs
from the U.S. statutory rate primarily due to losses of our foreign
subsidiaries, which are benefited at lower rates, net operating losses not
currently benefited, and items related to acquisitions, which are not deductible
for tax purposes. The rates for 2000 and 1999 were 38% and 29%, respectively.
The rate for 2000 was higher than the U.S. statutory rate primarily due to non-
deductible transaction costs related to acquisitions. The 1999 rate was lower
than the U.S. statutory rate primarily due to the utilization of prior loss
carryovers and other credits.

     Minority interest in net income of subsidiary.  Minority interest in net
income of subsidiary was not significant for the periods presented. The changes
in minority interest were attributable to the composition of earnings and losses
among certain of our international affiliates for each of the respective years.

FINANCIAL CONDITION AND LIQUIDITY

     Cash, cash equivalents and short-term investments decreased 11% to $1.01
billion in 2001 from $1.13 billion in 2000. Some of the major transactions that
impacted cash and short-term investments during the year were as follows:

     - Lower cash flows from our continuing operations in 2001.

     - Payments for companies acquired in 2001.

     - In the third quarter of 2001, we amended the master lease and security
       agreements entered into in April 2001 and March 2000. Pursuant to the
       amendments, we participated as a debt holder in the lease transactions
       replacing some of the existing lessor banks. As of December 31, 2001, our
       debt contribution of $242 million was recorded as non-current assets and
       deposits on the balance sheet. We cash collateralized $54 million of the
       remaining debt and equity investments of the lessors. This was also
       recorded as non-current assets and deposits. The net impact was a
       reduction in cash on the balance sheet. (See Note 12 of the Notes.)

     - In October 2001, we issued $490 million of 4% Convertible Subordinated
       Notes due in 2006. (See Note 8 of the Notes.)

     Cash, cash equivalents and short-term investments increased 71% to $1.13
billion in 2000 from $661.3 million in 1999. The increase was primarily a result
of proceeds from the issuance of the 2000 Convertible Notes, net of repayment of
the existing debt, and proceeds from our employee stock option and purchase
plans, partially offset by capital expenditures and cash paid for the purchase
of common stock under our repurchase program and the acquisition of non-public
technology companies. (See Note 2 of the Notes.) The increase was also
attributable to proceeds from the sale of investments in marketable equity
securities in the open market. At December 31, 2000, short-term investments
included $60.0 million of marketable equity securities. (See Note 5 of the
Notes.)

     WORKING CAPITAL.  Working capital decreased to $1.26 billion in 2001 from
$1.45 billion in 2000. The decrease was primarily a result of the following
factors:

     - Lower short-term investments resulting from (a) maturities and sales of
       securities available-for-sale, net of purchases and (b) marketable equity
       securities reclassified to long-term assets. (See Notes 5 and 8 of the
       Notes.) This decrease was offset in part by a higher cash balance at
       December 31, 2001 as compared to December 31, 2000. The higher cash
       balance is primarily due to the issuance of the 2001 Convertible Notes
       for $490 million, net of payments made for companies acquired in 2001 and
       the investment in non-current assets and deposits made under the amended
       master lease and security agreements (See Notes 2, 8 and 12 of the
       Notes.);

     - Lower accounts receivable due to decreased revenue and improved
       collections during the fourth quarter of 2001 as compared to the fourth
       quarter of 2000;

                                        40
<PAGE>

     - Lower inventory levels due to lower production volumes and increases in
       reserves for excess and obsolete inventory, offset in part by lower
       turnover; and

     - Higher accrued and other liabilities resulting primarily from acquisition
       and restructuring-related accruals.

     The decrease in working capital was offset in part by higher prepaid
expenses and other current assets due to a reclassification from property and
equipment to current assets held for sale, lower accounts payable that reflect
lower purchases during the fourth quarter of 2001 as compared to the fourth
quarter of 2000, lower accrued salaries and wages due to the various cost
reduction measures implemented in 2001 and lower income taxes payable due to the
timing of tax payments and the tax benefit recorded during 2001.

     Working capital increased to $1.45 billion in 2000 from $813.0 million in
1999. The increase was primarily a result of the following factors:

     - Higher short-term investments resulting from purchases of debt and equity
       securities, net of sales and maturities and marketable equity securities
       reclassified from long-term assets. (See Notes 5 and 8 of the Notes);

     - Higher net accounts receivable due to increased revenue and the timing of
       shipments when comparing the fourth quarter of 2000 to the fourth quarter
       of 1999. Shipments during the fourth quarter of 1999 were more linear
       throughout the quarter whereas during the fourth quarter of 2000,
       shipments increased towards the end of the quarter;

     - Lower current portion of long-term obligations resulting from repayment
       of the Revolver. (See Note 8 of the Notes.); and

     - Higher inventory reflecting the combination of higher sales in 2000 as
       compared to 1999 and lower than expected sales during the fourth quarter
       of 2000.

     The increase in working capital was offset in part by higher accrued
salaries, wages and benefits and other liabilities primarily due to increases in
headcount mainly resulting from acquisitions of companies (See Note 2 of the
Notes) as of December 31, 2000 as compared to December 31, 1999, higher income
taxes payable due to the higher income tax rate applied in 2000 primarily due to
the DataPath acquisition, and also by higher trade accounts payable compared to
1999.

     CASH AND CASH EQUIVALENTS GENERATED FROM OPERATING ACTIVITIES.  During
2001, we generated $119.5 million of cash and cash equivalents from operating
activities compared to $565.4 million generated in 2000. The decrease in cash
and cash equivalents provided by operating activities was primarily attributable
to a net loss for the year ended 2001 (before depreciation and amortization,
write-off of acquired in-process research and development, non-cash
restructuring charges, amortization of non-cash deferred stock compensation and
gains on stock investments), as compared to net income for the year ended 2000,
accompanied by a decrease in working capital as discussed above.

     During 2000, we generated $565.4 million of cash and cash equivalents from
operating activities compared to $443.8 million in 1999. The increase in net
cash and cash equivalents provided by operating activities was primarily
attributable to the following factors:

     - Higher net income (before depreciation and amortization, write-off of
       acquired in-process research and development, non-cash restructuring
       charges, amortization of non-cash deferred stock compensation and gains
       on stock investments); and

     - An increase in trade accounts payable, and accrued and other liabilities.
       The increase in trade accounts payable reflects higher purchases during
       the fourth quarter of 2000 as compared to the same period of 1999 and the
       timing of invoice receipt and payment. The increase in accrued and other
       liabilities was primarily attributable to higher income taxes payable due
       to a higher provision for income taxes for 2000, net of payment and
       higher deferred tax liabilities recorded in conjunction with the
       acquisition of DataPath.

                                        41
<PAGE>

     The increase in cash from operations was offset in part by an increase in
accounts receivable, inventories and prepaid expenses and other assets. The
increase in accounts receivable was primarily a result of higher revenues in the
fourth quarter of 2000 as compared to the same period of 1999 and the timing of
payment receipt. Higher inventory reflects the combination of higher sales in
2000 as compared to 1999 and lower than expected sales during the fourth quarter
of 2000. The increase in prepaid and other assets was primarily a result of
higher deferred tax assets recorded as of December 31, 2000 as compared to the
balance as of December 31, 1999 and increased capitalized software and
intellectual property during 2000 as compared to 1999.

     CASH AND CASH EQUIVALENTS USED IN INVESTING ACTIVITIES.  Cash and cash
equivalents used in investing activities was $146.8 million in 2001, compared to
$753.3 million used in 2000. The primary investing activities during 2001
included the following:

     - Lower proceeds from sale of stock investments;

     - Higher net payments towards acquisition of companies;

     - New investment in other non-current assets and deposits; (See Note 12 of
       the Notes.)

     - Higher maturities and sales of debt and equity securities available for
       sale, net of purchases as compared to 2000; and

     - Lower purchases of property and equipment, net of retirements.

     Cash and cash equivalents used in investing activities was $753.3 million
in 2000, compared to $472.0 million in 1999. The primary investing activities
during 2000 included the following:

     - Higher purchases of debt and equity securities available-for-sale and
       others, net of maturities and sales;

     - Higher purchases of property and equipment; and

     - Acquisitions of non-public technology companies (See Note 2 of the
       Notes).

     We believe that maintaining technological leadership in the highly
competitive worldwide semiconductor industry requires substantial ongoing
investment in advanced manufacturing capacity. Net capital additions were $224.3
million in 2001 and $276.6 million in 2000. In order to maintain our position as
a technological market leader, we expect the level of capital expenditures to be
less than $200 million in 2002.

     CASH AND CASH EQUIVALENTS PROVIDED BY FINANCING ACTIVITIES.  Cash and cash
equivalents provided by financing activities during 2001 was $554.3 million
compared to $183.7 million in 2000. The increase is primarily attributable to
higher proceeds from the issuance of the 2001 Convertible Notes, net of
repayment of bank debt and debt issuance costs as compared to the proceeds of
the 2000 Convertible Notes issued in 2000, net of repayment of the Revolver (See
Note 8 of the Notes). In addition, no shares were repurchased in 2001, as
compared to $49.3 million in repurchases in 2000. However, we generated lower
cash proceeds from our employee stock option and purchase plans in 2001 as
compared to the proceeds in 2000.

     Cash and cash equivalents provided by financing activities during 2000
totaled $183.7 million compared to $51.9 million in 1999. The increase was
primarily attributable to proceeds from the 2000 Convertible Notes, net of
repayment of the revolving credit facility (see Note 8 of the Notes) and higher
proceeds from our employee stock option and purchase plans in 2000. The increase
was offset in part by debt issuance costs associated with the 2000 Convertible
Notes and cash paid for the repurchase of our common stock under the repurchase
program in 2000.

     On October 30, 2001, we issued $490 million of 4% Convertible Subordinated
Notes (the "2001 Convertible Notes") due in 2006. The 2001 Convertible Notes are
subordinated to all existing and future senior debt, are convertible at the
holder's option at any time after 60 days following issuance, into shares of our
company's common stock at a conversion price of $26.339 per share. The 2001
Convertible Notes are redeemable at our option, in whole or in part, on at least
30 days notice at any time on or after November 6, 2004. Each holder of the 2001
Convertible Notes has the right to cause us to repurchase all of such holder's
convertible notes at 100% of their principal amount plus accrued interest upon
the occurrence of any fundamental change. Interest is payable semiannually. We
paid approximately $13.5 million for debt issuance costs related to the

                                        42
<PAGE>

2001 Convertible Notes. The debt issuance costs are being amortized using the
interest method. The net proceeds from the 2001 Convertible Notes were used to
repay bank debt outstanding with a balance of approximately $200 million as of
September 30, 2001 as described below.

     On September 28, 2001, we entered into a Credit Agreement with Bank of
America, N.A. and Banc of America Securities LLC that provided for borrowings up
to $200 million through September 26, 2002. We borrowed $200 million under the
Credit Agreement as of September 30, 2001, with an interest rate based on LIBOR.
The obligation was secured by inventory and accounts receivable. In October
2001, the borrowings outstanding under the Credit Agreement were repaid in full
with the proceeds of the 2001 Convertible Notes and the Credit Agreement was
terminated.

     On February 18, 2000, we issued $500 million of 4% Convertible Subordinated
Notes (the "2000 Convertible Notes") due in 2005. The 2000 Convertible Notes are
subordinated to all existing and future senior debt, are convertible at the
holder's option at any time after 60 days following issuance, into shares of our
company's common stock at a conversion price of $70.2845 per share. The 2000
Convertible Notes are redeemable at our option, in whole or in part, on at least
30 days notice at any time on or after February 20, 2003. Each holder of the
2000 Convertible Notes has the right to cause us to repurchase all of such
holder's convertible notes at 100% of their principal amount plus accrued
interest upon the occurrence of any fundamental change. Interest is payable
semiannually. We paid approximately $15.3 million for debt issuance costs
related to the 2000 Convertible Notes. The debt issuance costs are being
amortized using the interest method. The net proceeds from the 2000 Convertible
Notes were used to repay bank debt outstanding with a balance of approximately
$380 million as of December 31, 1999 as described below.

     During March 1999, we issued $345 million of 4 1/4% Convertible
Subordinated Notes (the "1999 Convertible Notes") due in 2004. The 1999
Convertible Notes are subordinated to all existing and future senior debt, are
convertible at the holder's option at any time after 60 days following issuance,
into shares of our company's common stock at a conversion price of $15.6765 per
share. The 1999 Convertible Notes are redeemable at our option, in whole or in
part, on at least 30 days notice at any time on or after March 20, 2002. Each
holder of the convertible notes has the right to cause us to repurchase all of
such holder's convertible notes at 100% of their principal amount plus accrued
interest upon the occurrence of any fundamental change. Interest is payable
semiannually. We paid approximately $9.5 million for debt issuance costs related
to the 1999 Convertible Notes. The amount was capitalized in other assets and is
being amortized over the life of the 1999 Convertible Notes using the interest
method. The net proceeds of the 1999 Convertible Notes were used to repay
existing debt obligations.

     The term fundamental change referred to above means the occurrence of any
transaction or event such as an exchange offer, liquidation, tender offer,
consolidation, merger, or combination.

     On August 5, 1998, we entered into a credit agreement with ABN AMRO Bank
N.V. ("ABN AMRO"). The credit agreement was restated and superseded by the
Amended and Restated Credit Agreement dated as of September 22, 1998 by and
among us, LSI Logic Japan Semiconductor, Inc. ("JSI") and ABN AMRO, and was
thereafter syndicated to a group of lenders determined by ABN AMRO and us
("Notes payable to banks"). The credit agreement consisted of two credit
facilities: a $575 million senior unsecured reducing revolving credit facility
("Revolver"), and a $150 million senior unsecured revolving credit facility
("364-day Facility"). On April 21, 2000, the credit agreement was superseded by
the Second Amended and Restated Credit Agreement by and among us, JSI, ABN AMRO
and a group of lenders determined by ABN AMRO to terminate the yen sub-facility
and modify certain covenant requirements.

     On March 14, 2001, the Second Amended and Restated Credit Agreement was
amended to reduce the total revolving commitment by $165 million from $240
million to $75 million. On the effective date of this reduction, the revolving
commitment of each lender was reduced accordingly. The Second Amended and
Restated Credit Agreement was terminated in August 2001.

     It is our policy to reinvest our earnings internally and we do not
anticipate paying any cash dividends to stockholders in the foreseeable future.

                                        43
<PAGE>

     In order to remain competitive, we must continue to make significant
investments in new facilities and capital equipment. We may seek additional
equity or debt financing from time to time. We believe that our existing liquid
resources and funds generated from operations, combined with funds from such
financing and our ability to borrow funds, will be adequate to meet our
operating and capital requirements and obligations through the foreseeable
future. However, we cannot be certain that additional financing will be
available on favorable terms. Moreover, any future equity or convertible debt
financing will decrease the percentage of equity ownership of existing
stockholders and may result in dilution, depending on the price at which the
equity is sold or the debt is converted.

     Fluctuations in our stock price impact the prices of our outstanding
convertible securities and the likelihood of the convertible securities being
converted into cash or equity. If we are required to redeem any of the
convertible securities for cash it may affect our liquidity position.

     As of December 31, 2001 we had operating leases financing certain wafer
fabrication equipment (See Note 12 of the Notes). The debt related to operating
leases is not reflected on the balance sheet.

RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2001, the Financial Accounting Standards Board ("FASB") issued FASB
Statements Nos. 141 and 142 (SFAS 141 and SFAS 142), "Business Combinations" and
"Goodwill and Other Intangible Assets." SFAS 141 replaces APB 16 and eliminates
pooling-of-interests accounting prospectively. It also provides guidance on
purchase accounting related to the recognition of intangible assets and
accounting for negative goodwill. SFAS 142 changes the accounting for goodwill
from an amortization method to an impairment-only approach. Under SFAS 142,
goodwill and indefinite-lived intangibles will be tested annually and whenever
events or circumstances occur indicating that they might be impaired. Goodwill
is tested for impairment employing a two-step method. First the fair value of
the reporting unit is compared to its carrying amount. If the fair value is less
than the carrying amount, the impairment is measured as the excess of recorded
goodwill over its implied fair value. Indefinite-lived intangibles are tested
for impairment by comparing the carrying amount to the fair value. SFAS 141 and
SFAS 142 are effective for all business combinations completed after June 30,
2001. Upon adoption of SFAS 142, amortization of goodwill recorded for business
combinations consummated prior to July 1, 2001 will cease, and intangible assets
acquired prior to July 1, 2001 that do not meet the criteria for recognition
under SFAS 141 will be reclassified to goodwill. We adopted SFAS 142 on January
1, 2002, the beginning of fiscal 2002. As a result of the adoption of SFAS 142,
amortization of goodwill and intangibles will be lower by approximately $112
million in 2002 as compared to 2001 and approximately $952 million of goodwill
and indefinite-lived intangibles will no longer be amortized. We have completed
the transitional goodwill impairment assessment in accordance with SFAS 142 and
concluded that goodwill is not impaired as of January 1, 2002.

     In August 2001, the FASB issued Statement No. 143 ("SFAS 143"), "Accounting
for Asset Retirement Obligations." SFAS 143 addresses financial accounting and
reporting for obligations associated with the retirement of tangible long-lived
assets and the associated asset retirement costs. The Statement applies to all
entities. It applies to legal obligations associated with the retirement of
long-lived assets that result from the acquisition, construction, development,
and/or the normal operation of a long-lived asset, except for certain
obligations of lessees. We adopted SFAS 143 on January 1, 2002 and it did not
have a significant effect on our financial position and results of operations.

     In October 2001, the FASB issued Statement No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets." SFAS 144 addresses financial
accounting and reporting for the impairment of long-lived assets and for
long-lived assets to be disposed. We adopted SFAS 144 on January 1, 2002 and it
did not have a significant effect on our financial position and results of
operations.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     We have foreign subsidiaries that operate and sell our products in various
global markets. We purchase a substantial portion of our raw materials and
equipment from foreign suppliers and incur labor and other operating costs in
foreign currencies, particularly at our Japanese manufacturing facilities. As a
result, our

                                        44
<PAGE>

cash flow and earnings are exposed to fluctuations in foreign currency exchange
rates. We attempt to limit these exposures through operational strategies and
financial market instruments. We use various hedge instruments, primarily
forward contracts with maturities of six months or less and currency option
contracts, to manage our exposure associated with net asset and liability
positions and cash flows denominated in non-functional currencies. We did not
purchase or hold derivative financial instruments for trading purposes as of
December 31, 2001 and 2000.

     Interest rate sensitivity.  We are subject to interest rate risk on our
investment portfolio and outstanding debt. An interest rate move of 41
basis-points (10% of our weighted-average worldwide interest rate in 2001)
affecting our floating-rate financial instruments as of December 31, 2001,
including both debt obligations and investments, would not have a significant
effect on our financial position, results of operations and cash flows over the
next fiscal year, assuming that the investment balance remains consistent. In
2000, an interest rate move of 41 basis points (10% of our weighted-average
worldwide interest rate in 2000) affecting our interest sensitive investments
would also not have had a significant effect on our financial position, results
of operations and cash flows.

     Foreign currency exchange risk.  Based on our overall currency rate
exposures at December 31, 2001, including derivative financial instruments and
nonfunctional currency denominated receivables and payables, a near-term 10%
appreciation or depreciation of the U.S. dollar would not have a significant
effect on our financial position, results of operations and cash flows over the
next fiscal year. In 2000 and 1999, a near-term 10% appreciation or depreciation
of the U.S. dollar would also not have had a significant effect.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES

     Nature of business.  LSI Logic Corporation ("the Company" or "LSI") is a
leading supplier of high-performance integrated circuits and highly scalable
enterprise storage systems. The Company is focused on the four markets of
consumer products, communications, storage components and storage area network
("SAN") systems.

     Segment reporting.  The Company operates in two reportable segments: the
Semiconductor segment and the SAN Systems segment. In the Semiconductor segment,
the Company uses advanced process technology and comprehensive design
methodologies to design, develop, manufacture and market highly complex
integrated circuits. These system-on-a-chip solutions include both application
specific integrated circuits, commonly referred to as ASICs; application
specific standard products in silicon, or ASSPs; as well as Redundant Array of
Independent Disks ("RAID") host bus adapters and related products; and services.
In the SAN Systems segment, the Company designs, manufactures, markets and
supports high-performance, highly scaleable open storage area network systems,
storage solutions and a complete line of RAID systems, subsystems and related
software. (See Note 11 of the Notes to the Consolidated Financial Statements
referred to hereafter as "Notes".)

     Basis of presentation.  The consolidated financial statements include the
accounts of the Company and all of its subsidiaries. Intercompany transactions
and balances have been eliminated in consolidation. Assets and liabilities of
certain foreign operations are translated to U.S. dollars at current rates of
exchange and revenues and expenses are translated using weighted average rates.
Accounts denominated in foreign currencies have been remeasured into functional
currencies before translation into U.S. dollars. Foreign currency transaction
gains and losses are included as a component of interest income and other. Gains
and losses from foreign currency translation are included as a separate
component of comprehensive income.

     On January 25, 2000, the Company announced a two-for-one stock split, which
was declared by the Board of Directors as a 100% stock dividend payable to
stockholders of record on February 4, 2000 as one new share of common stock for
each share held on that date. The newly issued common stock shares were
distributed on February 16, 2000. In the Notes, stockholders' equity has been
restated to give retroactive recognition to the two-for-one common stock split
announced on January 25, 2000 for all periods presented by reclassifying the par
value of the newly issued shares arising from the split from additional paid-in
capital to common stock. In addition, all references in the financial statements
to number of shares, per share amounts, stock option data and market prices of
the Company's common stock have been restated.

  2001 ACQUISITIONS

     During 2001, the Company acquired C-Cube Microsystems Inc. ("C-Cube") and
certain tangible and intangible assets associated with the RAID business of
American Megatrends, Inc. ("AMI"). The acquisitions were accounted for as
purchases and, accordingly, the estimated fair value of assets acquired and
liabilities assumed and the results of operations were included in the Company's
consolidated financial statements as of the effective date of each acquisition,
through the end of the period. These transactions are summarized below. There
were no significant differences between accounting policies of LSI and the
companies acquired. (See Note 2 of the Notes.)

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  2000 AND 1999 ACQUISITIONS

     During 2000, the Company acquired a division of NeoMagic Corporation
("NeoMagic"), a division of Cacheware, Inc. ("Cacheware"), Intraserver
Technology, Inc. ("Intraserver"), DataPath Systems, Inc. ("DataPath"), ParaVoice
Technologies, Inc. ("ParaVoice") and Syntax Systems, Inc. ("Syntax"). The
acquisitions were accounted for as purchases and, accordingly, the estimated
fair value of assets acquired and liabilities assumed and the results of
operations were included in the Company's consolidated financial statements as
of the effective date of each acquisition, through the end of the period.

     These transactions are summarized below. There were no significant
differences between the accounting policies of LSI and the companies acquired.
(See Note 2 of the Notes.)

</Table>

     In the second quarter of 2001, the NeoMagic research project was abandoned
and the remaining intangibles and goodwill recorded in connection with the
project were written off to other non-recurring items. (See Note 4 of the
Notes.)

     On June 22, 1999, the Company and SEEQ Technology, Inc. ("SEEQ") were
combined in a transaction accounted for as a pooling of interests. All financial
information has been restated retroactively to reflect the combined operations
of the Company and SEEQ as if the combination had occurred at the beginning of
the earliest period presented. (See Note 2 of the Notes.) Prior to the
combination, SEEQ's fiscal year-end was the last Sunday in September of each
year, whereas the Company operates on a year ending on December 31. SEEQ's
financial information has been recast to conform to the Company's year-end.
There were no significant differences between the accounting policies of the
Company and SEEQ.

     Minority interest in subsidiary represents the minority stockholders'
proportionate share of the net assets and the results of operations of the
Company's majority-owned subsidiary. Sales of common stock of the Company's
subsidiary and purchases of such shares may result in changes in the Company's
proportionate share of the subsidiary's net assets.

     The preparation of financial statements in conformity with generally
accepted accounting principles 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 consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting periods. Actual results could differ materially from these
estimates.

     Certain items previously reported in specific financial statement captions
have been reclassified to conform to the 2001 presentation.

     Cash equivalents and short-term investments.  All highly liquid investments
purchased with an original maturity of 90 days or less are considered to be cash
equivalents and are classified as held-to-maturity. Marketable short-term
investments are generally classified and accounted for as available-for-sale.
Management determines the appropriate classification of debt and equity
securities at the time of purchase and reassesses the classification at each
reporting date. Investments in debt and equity securities classified as held-

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

to-maturity are reported at amortized cost plus accrued interest, and securities
classified as available-for-sale are reported at fair value with unrealized
gains and losses, net of related tax, recorded as a separate component of
comprehensive income in stockholders' equity until realized (See Note 5 of the
Notes). Gains and losses on securities sold are determined based on the specific
identification method and are included in interest income and other. For all
investment securities, unrealized losses that are other than temporary are
recognized in net income. The Company does not hold these securities for
speculative or trading purposes.

     Fair value disclosures of financial instruments.  The estimated fair value
of financial instruments is determined by the Company, using available market
information and valuation methodologies considered to be appropriate. However,
considerable judgment is required in interpreting market data to develop the
estimates of fair value. Accordingly, the estimates presented herein are not
necessarily indicative of the amounts that the Company could realize in a
current market exchange. The use of different market assumptions and/or
estimation methodologies could have a significant effect on the estimated fair
value amounts. At December 31, 2001, the estimated fair values of the 2001, 2000
and 1999 Convertible Subordinated Notes were $444.7 million, $418.8 million and
$387.2 million, respectively. At December 31, 2000, the estimated fair values of
the 2000 and 1999 Convertible Subordinated Notes were $356.9 million and $388.6
million, respectively.

     Derivative instruments.  The Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments
and Hedging Activities," as amended by SFAS Nos. 137 and 138 as of January 1,
2001. SFAS No. 133 requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. It further provides criteria for derivative
instruments to be designated as fair value, cash flow and foreign currency
hedges and establishes respective accounting standards for reporting changes in
the fair value of the instruments. All of the Company's derivative instruments
are recorded at their fair value in other current assets or other accrued
liabilities. (See Note 6 of the Notes.) The transition adjustment upon adoption
of SFAS No. 133 was not material.

     On the date a derivative contract is entered into, the Company designates
its derivative as either a hedge of the fair value of a recognized asset or
liability ("fair-value" hedge), as a hedge of the variability of cash flows to
be received ("cash-flow" hedge), or as a foreign-currency hedge. Changes in the
fair value of a derivative that is highly effective, and is designated and
qualifies as a fair-value hedge, along with the loss or gain on the hedged asset
or liability that is attributable to the hedged risk (including losses or gains
on firm commitments), are recorded in current period earnings. Changes in the
fair value of a derivative that is highly effective, and is designated and
qualifies as a cash-flow hedge, are recorded in other comprehensive income,
until earnings are affected by the variability of the cash flows. Changes in the
fair value of derivatives that are highly effective, and are designated and
qualify as a foreign-currency hedge, are recorded in either current period
earnings or other comprehensive income, depending on whether the hedge
transaction is a fair-value hedge (e.g., a hedge of a firm commitment that is to
be settled in a foreign currency) or a cash-flow hedge (e.g., a
foreign-currency-denominated forecasted transaction). The Company's derivative
instruments at December 31, 2001 and 2000 were designated as foreign currency
fair-value hedges.

     The Company formally documents all relationships between hedging
instruments and hedged items, as well as its risk management objective and
strategy for undertaking various hedge transactions. This process includes
linking all derivatives that are designated as fair-value, cash-flow or
foreign-currency hedges to specific assets and liabilities on the balance sheet
or to specific firm commitments or forecasted transactions. The Company also
assesses, both at the hedge's inception and on an ongoing basis, whether the
derivatives that are used in hedging transactions are highly effective in
offsetting changes in fair values or cash flows of the hedged items. If it were
determined that a derivative is not highly effective as a hedge or that it has
ceased to be a highly effective hedge, the Company would discontinue hedge
accounting prospectively, as discussed below.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company would discontinue hedge accounting prospectively when (1) it is
determined that the derivative is no longer effective in offsetting changes in
the fair value or cash flows of a hedged item (including firm commitments or
forecasted transactions); (2) the derivative expires or is sold, terminated or
exercised; (3) the derivative is no longer designated as a hedge instrument,
because it is unlikely that a forecasted transaction will occur; (4) the hedged
firm commitment no longer meets the definition of a firm commitment; or (5)
management determines that designation of the derivative as a hedge instrument
is no longer appropriate.

     When hedge accounting is discontinued because it is determined that the
derivative no longer qualifies as an effective fair-value hedge, the derivative
will continue to be carried on the balance sheet at its fair value, and the
hedged asset or liability will no longer be adjusted for changes in fair value.
When hedge accounting is discontinued because the hedged item no longer meets
the definition of a firm commitment, the derivative will continue to be carried
on the balance sheet at its fair value, and any asset or liability that was
recorded pursuant to recognition of the firm commitment will be removed from the
balance sheet and recognized as a gain or loss in current-period earnings. When
hedge accounting is discontinued because it is probable that a forecasted
transaction will not occur, the derivative will continue to be carried on the
balance sheet at its fair value, and gains and losses that were accumulated in
other comprehensive income will be recognized immediately in earnings. In all
other situations in which hedge accounting is discontinued, the derivative will
be carried at its fair value on the balance sheet, with changes in its fair
value recognized in current period earnings.

     Concentration of credit risk of financial instruments.  Financial
instruments that potentially subject the Company to credit risk consist of cash
equivalents, short-term investments and accounts receivable. Cash equivalents
and short-term investments are maintained with high quality institutions, the
composition and maturities of which are regularly monitored by management. A
majority of the Company's trade receivables are derived from sales to large
multinational computer, communication, networking and consumer electronics
manufacturers, with the remainder distributed across other industries. As of
December 31, 2001, two customers each accounted for 12% of consolidated trade
receivables. No customers accounted for greater than or equal to 10% of trade
receivables as of December 31, 2000. Concentrations of credit risk with respect
to all other trade receivables are considered to be limited due to the quantity
of customers comprising the Company's customer base and their dispersion across
industries and geographies. One customer accounted for 18% of the Company's
total consolidated revenues for the year ended December 31, 2001, and another
customer represented 12% and 11% of the Company's consolidated revenues for the
years ended December 31, 2000 and 1999, respectively. The Company performs
ongoing credit evaluations of its customers' financial condition and requires
collateral as considered necessary. Write-offs of uncollectable amounts have not
been significant.

     Inventories.  Inventories are stated at the lower of cost or market. Cost
is determined on a first-in, first-out basis for raw materials and is computed
on a currently adjusted standard basis (which approximates first-in, first-out)
for work-in-process and finished goods. Inventory reserves are established when
conditions indicate that the selling price could be less than cost due to
physical deterioration, obsolescence, changes in price levels, or other causes.
Reserves are established for excess inventory generally based on inventory
levels in excess of 12 months judged demand for each specific product.

     Property and equipment.  Property and equipment are recorded at cost and
include interest on funds borrowed during the construction period. Depreciation
and amortization are calculated based on the straight-

line method. Depreciation of equipment and buildings, in general, is computed
using the assets' estimated useful lives as presented below:

<Table>
<S>                                                            <C>
Buildings and improvements..................................   20-40 years
Equipment...................................................     3-6 years
Furniture and fixtures......................................     3-5 years
</Table>

     Amortization of leasehold improvements is computed using the shorter of the
remaining term of the Company's facility leases or the estimated useful lives of
the improvements. Depreciation for income tax purposes is computed using
accelerated methods.

     Preproduction engineering costs.  In April 1998, the Accounting Standards
Executive Committee of the AICPA released SOP No. 98-5, "Reporting on the Costs
of Start-up Activities." The SOP is effective for fiscal years beginning after
December 15, 1998 and requires companies to expense all costs incurred or
unamortized in connection with start-up activities. Accordingly, the Company
expensed the unamortized preproduction balance of $92 million, net of tax,
associated with the Gresham manufacturing facility on January 1, 1999 and has
presented it as a cumulative effect of a change in accounting principle in
accordance with the SOP No. 98-5.

     Goodwill and other intangibles.  Goodwill and other intangibles acquired in
connection with business acquisitions and the purchase of common stock from
minority stockholders were approximately $1,661 million and $737 million, and
related accumulated amortization was $341 million and $156 million at December
31, 2001 and 2000, respectively. (See Note 2 of the Notes.) The acquisitions
were accounted for as purchases, and the excess of the purchase price over the
fair value of assets acquired was allocated to existing technology, customer
base, workforce in place, trademarks and residual goodwill, which are being
amortized using the straight-line method over a weighted average life of two to
six years. Goodwill and other intangibles are evaluated for impairment based on
the related estimated undiscounted cash flows. The goodwill and identifiable
intangible assets from the acquired RAID division of AMI has been accounted for
in accordance with the Financial Accounting Standards Board Statement No. 141,
"Business Combinations" and Financial Accounting Standards Board Statement No.
142, "Goodwill and Other Intangible Assets." (See Note 2 of the Notes.)

     Other assets.  Long-term investments in marketable and restricted shares of
technology companies are included in other assets. The marketable investments
are accounted for as available-for-sale and are reported at fair value with
unrealized gains and losses, net of related tax, recorded as a separate
component of comprehensive income in stockholders' equity until realized in
accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and
Equity Securities." (See Note 5 of the Notes.) Gains and losses on securities
sold are based on the specific identification method and are included in gain on
sale of equity securities. The investments in restricted and non-marketable
shares are recorded at cost. For all investment securities, unrealized losses
that are other than temporary are recognized as a component of interest income
and other. Circumstances that indicate an other than temporary decline may
include subsequent "down" financing rounds, decreases in quoted market price and
declines in results of operations of the issuer. The Company does not hold these
securities for speculative or trading purposes.

     Software.  The Company capitalizes external costs related to the purchase
and implementation of software projects used for business operations and
engineering design activities. Capitalized software costs primarily include
purchased software and external consulting fees. Capitalized software projects
are amortized over the estimated useful lives of the projects, typically a two
to five year period. The Company had $178 million and $137 million of
capitalized software costs and $131 million and $72 million of accumulated
amortization included in other assets at December 31, 2001 and 2000,
respectively. Software amortization totaling $56 million, $41 million and $25
million was included in the Company's results of operations during 2001, 2000
and 1999.

     Self-insurance.  The Company retains certain exposures in its insurance
plan under self-insurance programs. Reserves for claims made and reserves for
estimated claims incurred but not yet reported are recorded as current
liabilities.

     Revenue recognition.  Product revenue is primarily recognized upon shipment
with the exception of standard products sold to distributors. Revenue from
standard products sold to distributors is deferred until the distributor sells
the product to a third party. Revenue from the licensing of the Company's design
and manufacturing technology is recognized when the significant contractual
obligations have been fulfilled. Royalty revenue is recognized upon the sale of
products subject to royalties. The Company uses the percentage-of-completion
method for recognizing revenues on fixed-fee design arrangements. All amounts
billed to a customer related to shipping and handling are classified as revenue
while all costs incurred by the Company for shipping and handling are classified
as costs of goods sold.

     The provisions of Statement of Position 97-2, "Software Revenue
Recognition," as amended by Statement of Position 98-9 "Modification of SOP
97-2, Software Revenue Recognition, With Respect to Certain Transactions" are
applied to all transactions involving the sale of software products and hardware
transactions where the software is not incidental. For hardware transactions
where software is incidental, the fee is not bifurcated and separate accounting
guidance is not applied to the hardware and software elements. For hardware
transactions where no software is involved the provisions of Staff Accounting
Bulletin 101 "Revenue Recognition" are applied.

     Stock-based compensation.  The Company accounts for stock-based
compensation, including stock options granted and shares issued under the
Employee Stock Purchase Plan, using the intrinsic value method prescribed in APB
No. 25, "Accounting for Stock Issued to Employees," and related interpretations.
Compensation cost for stock options, if any, is recognized ratably over the
vesting period. The Company's policy is to grant options with an exercise price
equal to the quoted market price of the Company's stock on the grant date. The
Company provides additional pro forma disclosures as required under SFAS No.
123, "Accounting for Stock-Based Compensation." (See Note 9 of the Notes.)

     The Company adopted FASB Interpretation No. 44 ("FIN No. 44"), "Accounting
for Certain Transactions Involving Stock Compensation -- an Interpretation of
APB 25", on July 1, 2000. Amortization of non-cash deferred stock compensation
of $105 million and $41 million in 2001 and 2000, respectively, is due to
non-cash deferred stock compensation of $270 and $204 million recorded in
connection with the acquisitions of the RAID business of AMI, C-Cube, Syntax and
DataPath, which closed on August 31, 2001, May 11, 2001, November 29, 2000, and
July 14, 2000, respectively (See Note 2 of the Notes).

     Earnings per share.  Basic earnings per share ("EPS") is computed by
dividing net income available to common stockholders (numerator) by the weighted
average number of common shares outstanding (denominator) during the period.
Diluted EPS is computed using the weighted-average number of common and dilutive
potential common shares outstanding during the period. In computing diluted EPS,
the average stock price for the period is used in determining the number of
shares assumed to be repurchased upon the exercise of stock options. A
reconciliation of the numerators and denominators of the basic and diluted per
share amount computations is as follows:

     Options to purchase approximately 73,996,916 shares were outstanding at
December 31, 2001 and were excluded from the computation of diluted shares
because of their antidilutive effect on earnings per share as the Company
incurred a net loss for the year. Options to purchase approximately 6,573,340
shares and 4,122,000 shares were outstanding at December 31, 2000 and 1999,
respectively, but were not included in the computation of diluted shares for the
year ended December 31, 2000 and 1999, respectively, because the exercise prices
of these options were greater than the average market price of common shares for
the respective years. The exercise price of these options ranged from $0.01 to
$72.25 and $26.38 to $72.25 at December 31, 2001 and 2000, respectively.

     Related party transactions.  There were no significant related party
transactions during the years ended December 31, 2001, 2000 and 1999, other than
as listed in Notes 3 and 12 of the Notes.

     Comprehensive income.  Comprehensive income is defined as a change in
equity of a company during a period from transactions and other events and
circumstances excluding transactions resulting from investments by owners and
distributions to owners. The primary difference between net income and
comprehensive income, for the Company, arises from foreign currency translation
adjustments and unrealized gains or losses

on available-for-sale securities, net of applicable taxes. Comprehensive income
is shown in the statement of stockholders' equity. As of December 31, 2001, the
accumulated other comprehensive income consisted of $22 million of unrealized
gains on available-for-sale securities, net of the related tax effect of $12
million, and $8 million loss from foreign currency translation adjustments, net
of the related tax effect of $3 million. As of December 31, 2000, the
accumulated other comprehensive income consisted of $31 million of unrealized
gains on available-for-sale securities, net of the related tax effect of $17
million, and $23 million gain from foreign currency translation adjustments, net
of the related tax effect of $12 million. As of December 31, 1999, the
accumulated other comprehensive income consisted of $90 million of unrealized
gain on available-for-sale securities, net of the related tax effect of $48
million, and $56 million gain from foreign currency translation adjustments, net
of the related tax effect of $30 million.

NOTE 2 -- BUSINESS COMBINATIONS

     Acquisitions accounted for as purchases.  The estimated fair value of
acquired assets and assumed liabilities and the results of operations for
acquisitions accounted for as a purchase are included in the Company's
consolidated financial statements as of the effective date of the purchase,
through the end of the period. The total purchase price is allocated to the
estimated fair value of assets acquired and liabilities assumed based on
independent appraisals and management estimates. The fair value of common shares
issued for acquisitions was determined using the average closing stock price for
the period of two days before and after the date the number of LSI common shares
to be issued was fixed. The purchase price includes direct acquisition costs
consisting of investment banking, legal and accounting fees. There were no
significant differences between the accounting policies of the Company and the
acquired entities except as noted below.

     Deferred compensation.  On July 1, 2000, FIN No. 44 was adopted by the
Company as discussed in Note 1 of the Notes. In accordance with FIN No. 44, for
all acquisitions that closed after it's adoption, the intrinsic value of the
unvested options, restricted awards and warrants assumed as part of the
acquisitions as of the closing date of the acquisitions was recorded as deferred
stock compensation as a component of the purchase price to be amortized over the
respective vesting periods of the options and awards. The Company calculated the
value of restricted shares issued using the closing price of its common stock on
the date of consummation of the purchase. The fair value of the options and
warrants assumed was determined using the Black Scholes method. Deferred stock
compensation is included as a component of stockholders' equity and is amortized
over the vesting period of one to four years.

     The amounts of IPR&D were determined by identifying research projects for
which technological feasibility had not been established and no alternative
future uses existed as of the respective acquisition dates. The value of the
projects identified to be in progress was determined by estimating the future
cash flows from the projects once commercially feasible, discounting the net
cash flows back to their present value and then applying a percentage of
completion to the calculated value. The net cash flows from the identified
projects were based on estimates of revenues, cost of revenues, research and
development costs, selling general and administrative costs and applicable
income taxes for the projects. Total revenues for the projects are expected to
extend through the dates noted in the table above by acquisition. These
projections were based on estimates of market size and growth, expected trends
in technology and the expected timing of new product introductions by our
competitors and us. These estimates do not account for any potential synergies
that may be realized as a result of the acquisition and are in line with
industry averages and growth estimates.

     The percentage of completion for the projects was determined using one of
the following methods:

     - Percentage of research and development expenses.  Research and
       development expenses incurred as of the acquisition dates for the
       projects as a percentage of total research and development expenses to
       bring the projects to technological feasibility.

     - Project milestones.  Milestones representing management's estimate of
       effort, value added and degree of difficulty of the portion of the
       projects completed as of the acquisition dates, as compared to the
       remaining research and development to be completed to bring the projects
       to technological feasibility. The development process is grouped into
       three phases, with each phase containing between one and five milestones.
       The three phases are: (i) researching the market requirements and the
       engineering architecture and feasibility studies; (ii) design and
       verification milestones; and (iii) prototyping and testing the product
       (both internal and customer testing).

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     A discount rate is used for the projects to account for the risks
associated with the inherent uncertainties surrounding the successful
development of the IPR&D, market acceptance of the technology, the useful life
of the technology, the profitability level of such technology and the
uncertainty of technological advances, which could impact the estimates
described above. The Company applied a royalty rate by project by acquisition to
operating income to attribute value for dependency on predecessor core
technologies.

     Development of technologies that have not yet been completed remains a
substantial risk to the Company due to various factors, including the remaining
effort to achieve technological feasibility, rapidly changing customer markets
and competitive threats from other companies. Failure to bring the product to
market in a timely manner could adversely affect sales and profitability of the
Company in the future. Additionally, the value of other intangible assets
acquired may become impaired.

     Recent accounting pronouncements.  In July 2001, the Financial Accounting
Standards Board ("FASB") issued FASB Statements Nos. 141 and 142 (SFAS 141 and
SFAS 142), "Business Combinations" and "Goodwill and Other Intangible Assets."
SFAS 141 replaces APB 16 and eliminates pooling-of-interests accounting
prospectively. It also provides guidance on purchase accounting related to the
recognition of intangible assets and accounting for negative goodwill. SFAS 142
changes the accounting for goodwill from an amortization method to an
impairment-only approach. Under SFAS 142, goodwill and indefinite-lived
intangibles will be tested annually and whenever events or circumstances occur
indicating that they might be impaired. Goodwill is tested for impairment
employing a two-step method. First the fair value of the reporting unit is
compared to its carrying amount. If the fair value is less than the carrying
amount, the impairment is measured as the excess of recorded goodwill over its
implied fair value. Indefinite-lived intangibles are tested for impairment by
comparing the carrying amount to the fair value. SFAS 141 and SFAS 142 are
effective for all business combinations completed after June 30, 2001. Upon
adoption of SFAS 142, amortization of goodwill recorded for business
combinations consummated prior to July 1, 2001 will cease, and intangible assets
acquired prior to July 1, 2001 that do not meet the criteria for recognition
under SFAS 141 will be reclassified to goodwill. The Company will adopt SFAS 142
on January 1, 2002, the beginning of fiscal 2002, for all goodwill and
intangibles that arose before July 1, 2001. As a result of the adoption of SFAS
142, amortization of goodwill and intangibles will be lower by approximately
$112 million in 2002 as compared to 2001 and approximately $952 million of
goodwill and indefinite-lived intangibles will no longer be amortized. The
Company has completed the transitional goodwill impairment assessment in
accordance with SFAS 142 and concluded that goodwill is not impaired as of
January 1, 2002.

  2001

     Acquisition of the RAID business.  On August 31, 2001, the Company
finalized the Asset Purchase Agreement with American Megatrends, Inc. ("AMI").
Under the agreement, the Company acquired certain tangible and intangible assets
associated with AMI's Redundant Array of Independent Disks, or RAID, business.
The acquisition will enhance product offerings and be included in the
Semiconductor segment. The acquisition was accounted for as a purchase.

     The calculated value of deferred stock compensation includes certain
minimum guaranteed amounts. Deferred stock compensation will be amortized over
approximately two years.

     In-process research and development.  In connection with the purchase of
the RAID business, the Company recorded a $19.1 million charge for several IPR&D
projects during the third quarter of 2001. The projects were for development of
RAID technology applications. The percentage of completion for the projects was
determined based on the percentage of research and development expenses. The
discount rate used was 20% for the projects. Development of RAID technology
applications was started in early 2000 and 2001. As of August 31, 2001, the
Company estimated that the projects were from 12% to 62% complete.

     Useful life of intangible assets.  The amount allocated to current
technology and trademarks is being amortized over their estimated useful lives
of 4 and 5.5 years, respectively, using the straight-line method. The excess of
purchase price over net assets acquired is not being amortized. The
identification of intangibles and amortization periods were determined in
accordance with the recent accounting pronouncements as described above.

     Pro forma statement of earnings information has not been presented because
the effect of this acquisition was not material.

     ACQUISITION OF C-CUBE.  On March 26, 2001, the Company signed a definitive
merger agreement ("Merger Agreement") to acquire C-Cube Microsystems Inc.
("C-Cube"). In accordance with the Merger Agreement, the Company commenced an
exchange offer whereby it offered 0.79 of a share of common stock for each
outstanding share of C-Cube common stock. Under the terms of the Merger
Agreement, the exchange offer was followed by a merger in which the Company
acquired, at the same exchange ratio, the remaining shares of C-Cube common
stock not previously acquired in the exchange offer. Upon completion of the
merger, the Company assumed all options and warrants to purchase shares of
C-Cube common stock and converted them into options and warrants to purchase
shares of the Company's common stock. The merger was subject to customary
closing conditions, including the tender for exchange of at least a majority of
C-Cube's outstanding shares of common stock (including for purposes of the
calculation of the majority of shares, certain outstanding options and warrants
to purchase C-Cube shares). The acquisition was effective May 11, 2001. The
acquisition was accounted for as a purchase.

     The Company issued approximately 40.2 million shares of its common stock,
10.6 million options and 0.8 million warrants in exchange for the outstanding
ordinary shares, options and warrants of C-Cube, respectively. The fair value of
common shares issued was $18.73 per share. The acquisition is intended to

     In-process research and development.  In connection with the purchase of
C-Cube, the Company recorded a $77.5 million charge for various IPR&D projects.
The projects identified primarily consisted of digital video disc ("DVD"),
recordable digital video ("DVD-R"), Consumer Set-Top Box and Cable Modem. The
percentage of completion for the projects was determined based on the percentage
of research and development expenses. The discount rate used was 27.5% for these
projects. The development of these projects started in early 1999. As of May 11,
2001, the Company estimated the projects were approximately 84%, 62%, 61% and
69% complete for DVD, DVD-R, Consumer Set-Top Box and Cable Modem, respectively.

     Useful life of intangible assets.  The amount allocated to current
technology, trademarks, assembled workforce and excess of purchase price over
net assets acquired is being amortized over their estimated weighted average
useful life of six years using the straight-line method.

     Pro forma results.  The following pro forma summary is provided for
illustrative purposes only and is not necessarily indicative of the consolidated
results of operations for future periods or that actually would have been
realized had the Company and C-Cube been a consolidated entity during the
periods presented. The summary combines the results of operations as if C-Cube
had been acquired as of the beginning of the periods presented.

     The summary includes the impact of certain adjustments such as amortization
of intangibles and non-cash deferred stock compensation. Additionally, the
in-process research and development charge of $77.5 million discussed above has
been excluded from the periods presented as it arose from the acquisition of
C-Cube. The restructuring and other non-recurring charges of $219.6 million were
included in the pro forma calculation as the charges did not relate to the
acquisition of C-Cube. (See Note 4 of the Notes.)

  1999

     Merger with SEEQ.  On June 22, 1999, the Company and SEEQ were combined.
SEEQ was formed in January 13, 1981 and engaged in the development, production
and sale of state-of-the-art semiconductor data communications devices. The
stock-for-stock transaction was approved by the shareholders of SEEQ. In
December 1999, SEEQ was merged with and into LSI with LSI continuing as the
surviving corporation in the merger. As a result of the merger, the separate
existence of SEEQ ceased. Under the terms of the Agreement

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

and Plan of Reorganization and Merger, SEEQ's shareholders received 0.1518 of a
share of the Company's common stock for each SEEQ share. Accordingly, the
Company issued approximately 5 million shares of its common stock for all the
outstanding shares of SEEQ common stock. Additionally, outstanding options to
acquire SEEQ common stock as of the merger date were converted to options to
acquire 0.8 million shares of the Company's common stock.

     The merger was accounted for as a pooling of interests. Accordingly, the
Company's financial statements have been restated retroactively to include the
financial results of SEEQ for all periods presented. Selected financial
information for the combining entities included in the consolidated statements
of operations for the six-month period ended June 30, 1999 (unaudited), the

     Restructuring and merger-related expenses associated with the SEEQ
merger.  In connection with the merger with SEEQ on June 22, 1999, the Company
recorded approximately $2.9 million in restructuring charges and $5.5 million in
merger-related expenses, which included $0.5 million recorded by SEEQ in the
first quarter of 1999. The merger expenses related primarily to investment
banking and other professional fees directly attributable to the merger with
SEEQ. The restructuring charge was comprised of $1.9 million in write-downs of
fixed assets that were duplicative to the combined company, $0.5 million of exit
costs relating to non-cancelable building lease contracts and a $0.5 million
provision for severance costs related to the involuntary termination of certain
employees. The restructuring actions as outlined by the restructuring plan were
completed by June 30, 2000, one year from the date the reserve was taken.
Approximately $0.5 million of severance was paid to three employees terminated
during 1999.

     Acquisition of ZSP.  On April 14, 1999, the Company acquired all of the
outstanding capital stock of ZSP, a semiconductor company that designs and
markets programmable digital signal processors. The acquisition was accounted
for as a purchase. There were no significant differences between the accounting
policies of the Company and ZSP.

NOTE 3 -- LICENSE AGREEMENT

     In the second quarter of 1999, the Company and Silterra Malaysia Sdn. Bhd.
(formerly known as Wafer Technology (Malaysia) Sdn. Bhd.) ("Silterra") entered
into a technology transfer agreement under which the Company grants licenses to
Silterra with respect to certain of the Company's wafer fabrication technologies
and provides associated manufacturing training and related services. In
exchange, the Company receives cash consideration of $75 million and equity
consideration over three years for which transfers and obligations of the
Company are scheduled to occur. The equity consideration was valued at zero as
of December 31, 2001. The Company transferred technology to Silterra valued at
$20 million, $24 million and $15 million for the years ended December 31, 2001,
2000 and 1999, respectively. The amount was recorded as an offset to the
Company's R&D expenses. In addition, the Company provided engineering training
with a value of $2 million, $4 million and $2 million for the years ended
December 31, 2001, 2000 and 1999, respectively. The amount was recorded as an
offset to cost of revenues.

NOTE 4 -- RESTRUCTURING AND OTHER NON-RECURRING ITEMS

  2001

     The Company recorded approximately $219.6 million in restructuring and
non-recurring charges for the year ended December 31, 2001, consisting of $207.2
for restructuring of operations and $12.4 million for other non-recurring
charges.

  Restructuring

     In September 2001, the Company announced the consolidation of U.S.
manufacturing operations at Gresham, Oregon and the transfer of process research
and development from Santa Clara, California to Gresham, Oregon. The Company
also announced the closure of certain assembly activities in Fremont,
California, which will be transferred offshore. In September 2001, the Company
recorded a restructuring charge of $77 million for fixed asset write-downs due
to impairment in the U.S., losses on operating leases for equipment and
facilities, severance for approximately 600 employees across multiple company
activities and functions in the U.S., Europe, Japan and Asia Pacific as well as
other exit costs. In December 2001, the Company recorded $14 million of
additional fixed asset write-downs due to impairment for the Santa Clara
facility. The Company reclassified $25 million, representing the fair market
value of the assets identified above, from property, plant and equipment to
other current assets during the year to reflect the intention to dispose of the
assets within 12 months. In addition, in December 2001, approximately $4 million
in exit costs for the closure of the Santa Clara facility was recorded relating
primarily to labor and facilities charges.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In April 2001, the Company announced the closure of the Company's Colorado
Springs fabrication facility ("the facility") in August 2001. In May 2001, the
Company entered into a definitive agreement to sell the facility to a third
party. As part of the agreement, the Company agreed to purchase a minimum amount
of production wafers and die from the facility for a period of 18 months
following the close of the transaction. During the quarter ended June 30, 2001,
the Company recorded an impairment charge of $71 million relating to the
facility of which approximately $35 million was recorded in cost of sales and
$36 million was recorded in restructuring charges. The restructuring charges
consisted of fixed asset write-downs due to impairment, losses on operating
leases for equipment, severance for approximately 413 manufacturing employees
and other exit costs. On August 1, 2001, the Company announced the termination
of the agreement to sell the facility. The facility was closed in the fourth
quarter of 2001. In September 2001, the Company recorded an additional
restructuring charge of $55 million for fixed asset write-downs and other exit
costs associated with the planned closure of the facility. The additional asset
write-downs during the third quarter of 2001 were incurred to reflect the lower
value of the facility's assets if sold on a piecemeal basis rather than sold as
a facility in continued use. In addition, equipment market values continued to
decline in the third quarter of 2001. The Company reclassified approximately $62
million from property, plant and equipment to other current assets to reflect
the intention to dispose of the facility within the next 12 months. In December
2001, the Company recorded $1.5 million of additional fixed asset write-downs
due to impairment for the Colorado Springs facility. In addition, approximately
$3 million in exit costs for the closures of Colorado Springs facilities were
recorded relating primarily to labor and facilities charges.

     The Company recorded approximately $16 million in restructuring charges in
the second quarter of 2001 primarily associated with the write-down of fixed
assets due to impairment in the U.S., Japan and Hong Kong that will be disposed
of and severance charges for approximately 240 employees across multiple company
activities and functions in the U.S., Europe and Asia Pacific. As a result of
the continued decline in the equipment market during the third quarter of 2001,
the Company recorded an additional charge of $0.5 million during the third
quarter of 2001 to reflect the fair value of the equipment when sold. In
December 2001, the Company recorded $0.3 million of additional fixed asset
write-downs due to impairment in Japan. The Company plans to sell the assets and
accordingly has reclassified $2 million from property, plant and equipment to
other current assets to reflect the intention to sell the assets within the next
12 months.

     The fair value of assets determined to be impaired was based on independent
appraisals and management estimates. Given that current market conditions for
the sale of older fabrication facilities and related equipment may continue to
deteriorate, there can be no assurance that the Company will realize its current
net book value for the assets. The Company will reassess the realizability of
the carrying value of these assets at the end of each quarter until the assets
are sold or otherwise disposed of and additional adjustments may be necessary.

31, 2001, which is included in other accrued liabilities on the balance sheet:

---------------

(a)  Amounts utilized in 2001 reflect a non-cash write-down of fixed assets in
     the U.S., Japan and Hong Kong due to impairment of $133.8 million and cash
     payments for machinery and equipment decommissioning costs of $2.2 million.
     The fixed asset write-downs were accounted for as a reduction of the assets
     and did not result in a liability. The $3.8 million balance as of December
     31, 2001 relates to machinery and equipment decommissioning costs in the
     U.S.

(b)  Amounts utilized represent cash payments related to the severance of
     approximately 1180 employees during the year ended December 31, 2001. The
     $0.7 million balance as of December 31, 2001 will be paid during the first
     six months of 2002.

(c)  Amounts utilized represent cash payments.

  Other Non-Recurring Charges:

     The Company recorded approximately $12.4 million in other non-recurring
charges during 2001 as follows:

     - $8.1 million in charges associated with the write-down of intangible
       assets due to impairment. The majority of the intangible assets were
       originally acquired in the purchase of a division of NeoMagic in the
       second quarter of 2000.

     - $4.3 million in charges primarily consisting of the write-down of an
       investment in a marketable equity security and related purchased
       intellectual property.

  2000

     The Company recorded a restructuring of operations and other non-recurring
net charges of $2.8 million in 2000. This was primarily related to the loss on
an agreement entered into with a third party to outsource certain testing
services previously performed by us at our Fremont, California facility.

  1999

     During the third quarter of 1999, the Company completed the activities
underlying the restructuring plan, which was originally established in the third
quarter of 1998. During the year ended December 31, 1999, the Company utilized
$11.5 million of restructuring reserves, which consisted of severance payments
of $7.9 million for 358 employees terminated during the year, $2.3 million for
early lease contract terminations and to exit non-cancelable purchase
commitments, $0.7 million of manufacturing facility decommissioning costs in
Japan and other exit costs, and $0.6 million of currency translation
adjustments. During 1999, the Company recorded approximately $2.9 million in
restructuring charges and $5.5 million in merger-related expenses in connection
with the merger with SEEQ on June 22, 1999 (see Note 2 of the Notes.)

     During 1999, the Company determined that $10.5 million of the restructuring
reserve from 1998 would not be utilized because of a change in management's
estimate of the reserve requirements. The amount consisted of the following:

     - $3.9 million of reserves for lease terminations and non-cancelable
       purchase commitments, primarily in the U.S. and Europe;

     - $3.7 million of excess severance reserves in the U.S., Japan and Europe;

     - $2.0 million of reserves for manufacturing facility decommissioning costs
       and other exit costs primarily in the U.S. and Japan; and

     - $0.9 million of related cumulative translation adjustments.

<PAGE>
                             LSI LOGIC CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

       The change in management estimates of the reserve requirements stemmed
       primarily from the following factors:

     - A significant increase in the requirement for manufacturing capacity to
       meet expected sales growth, which resulted in retention of certain
       employees originally targeted for termination of employment and in
       reversal of the reserve for decommissioning costs as a result of
       retention of the U.S. and Japan operation facilities originally targeted
       for sale; and

     - The Company's ability to exit lease commitments and non-cancelable
       purchase commitments on more favorable terms than originally anticipated
       in the U.S. and Europe.

     Accordingly, the restructuring reserve reversal was included in the
determination of income from operations for the year ended December 31, 1999.

As of December 31, 2001, an unrealized gain of $22 million, net of the related
tax effect of $12 million, on these equity securities was included in
accumulated comprehensive income. As of December 31, 2000, an unrealized gain of
$31 million, net of the related tax effect of $17 million, on these equity

     During 2001, the Company sold equity securities for $8 million in the open
market, realizing a pre-tax gain of approximately $5 million. During 2000, the
Company sold equity securities for $79 million in the open market, realizing a

     During the year ended December 31, 2001, the Company wrote down to
estimated fair value equity investments in certain technology companies. The
write down was for approximately $19 million. The decline in value of the
investments was considered by management to be other than temporary. The Company
also realized a pre-tax gain of approximately $4 million associated with equity
securities of a certain technology company that was acquired by another
technology company during the year.

NOTE 6 -- DERIVATIVE INSTRUMENTS

     The Company has foreign subsidiaries that operate and sell the Company's
products in various global markets. As a result, the Company is exposed to
changes in foreign currency exchange rates and interest rates. The Company
utilizes various hedge instruments, primarily forward contracts and currency
option contracts, to manage its exposure associated with firm intercompany and
third-party transactions and net asset and liability positions denominated in
non-functional currencies. The Company does not hold derivative financial
instruments for speculative or trading purposes.

  FORWARD CONTRACTS

     Forward contracts are used to hedge certain cash flows denominated in
non-functional currencies. Changes in the fair value of forward contracts due to
changes in time value are excluded from the assessment of effectiveness and are
recognized in other income and expense. At December 31, 2001, there was one
forward contract outstanding, it was set to expire within one month and is
designated as a foreign currency fair-value hedge in accordance with SFAS No.
133. For the year ended December 31, 2001, the change in time value of the
forward contracts was not significant. The Company did not record any gains or
losses due to hedge ineffectiveness during 2001.

     Forward exchange contracts are also used to hedge certain foreign
currency-denominated assets or liabilities. These derivatives do not qualify for
SFAS No. 133 hedge accounting treatment. Accordingly, changes in the fair value
of these hedges are recorded immediately in earnings to offset the changes in
fair value of the assets or liabilities being hedged. The related gains and
losses included in other income and expense was not significant.

  OPTION CONTRACTS

     The Company also enters into purchased currency option contracts that are
designated as foreign currency cash-flow hedges of third-party yen revenue
exposures. Changes in the fair value of currency option contracts due to changes
in time value are excluded from the assessment of effectiveness and are
recognized in other income and expense. There were no option contracts
outstanding as of December 31, 2001 and 2000. For the year ended December 31,
2001, the change in option time value was approximately $4 million. During the
year ended December 31, 2001, an amount of $6 million was reclassified to
revenue from other comprehensive

record any gains or losses due to hedge ineffectiveness for the year ended

     The Company recorded, as a component of cost of revenues, additional excess
inventory and related charges of $211 million for the year ended December 31,
2001. The charges were due to inventory production in anticipation of closing
the Company's Colorado Springs manufacturing facility (see Note 4 of the Notes),
a sudden and significant decrease in forecasted revenue, and significant
underutilization related to a temporary idling of the Company's fabrication
facilities due to reduced demand. The charges were calculated in accordance with
the Company's policy, which is primarily based on inventory levels in excess of
12 month judged demand for each specific product.

     An allocation of interest costs incurred on borrowings during a period
required to complete construction of the asset is capitalized as part of the
historical cost of acquiring certain assets. Gross capitalized interest included
in property and equipment totaled $29 million at December 31, 2001 and 2000. No
interest was capitalized during 2001 and 2000. Accumulated amortization of
capitalized interest was $17 million and $15 million at December 31, 2001 and
2000, respectively.

     On August 5, 1998, the Company entered into a credit agreement with ABN

among the Company, LSI Logic Japan Semiconductor, Inc. ("JSI") and ABN AMRO, and
was thereafter syndicated to a group of lenders determined by ABN AMRO and the
Company ("Notes payable to banks"). The credit agreement consisted of two credit
facilities: a $575 million senior unsecured reducing revolving credit facility
("Revolver"), and a $150 million senior unsecured revolving credit facility
("364-day Facility"). On April 21, 2000, the credit agreement was superseded by
the Second Amended and Restated Credit Agreement by and among the Company, JSI,
ABN AMRO and a group of lenders determined by ABN AMRO to terminate the yen
sub-facility and modify certain covenant requirements.

amended to reduce the total revolving commitment by $165 million from $240

stock split as if it occurred for all periods presented.

     Stock repurchase program.  There were no stock repurchases in 2001. On July
28, 2000, the Company's Board of Directors authorized a new stock repurchase
program in which up to 5 million shares of the Company's common stock may be
repurchased in the open market from time to time. Accordingly, the Company
repurchased 1.5 million shares of its common stock in the open market for
approximately $49.3 million during the year ended December 31, 2000. The
transactions were recorded as reductions to common stock and additional paid-in
capital.

     Stock option plans.  On August 13, 1999, the Board of Directors approved
the 1999 Nonstatutory Stock Option Plan ("1999 NSO Plan") under which 14 million
shares were reserved for issuance. In August 2000, 12 million additional shares
were approved by the Board of Directors for issuance, and in May 2001, 13
million additional shares were approved for issuance, for a total of 39 million
shares reserved for issuance under the 1999 NSO Plan. Under the terms of the
1999 NSO Plan, the Company may grant stock options to its employees, excluding
officers, with an exercise price that is no less than the fair market value of
the stock on the date of grant. The term of each option is determined by the
Board of Directors and is generally ten years. Options generally vest in annual
increments of 25% per year commencing one year from the date of grant.

     The 1991 Equity Incentive Plan enables the Company to grant stock options
to its employees and consultants. Stock options may be granted with an exercise
price no less than the fair value of the stock on the date of grant. The term of
each option is determined by the Board of Directors and is generally ten years.
Options generally vest in annual increments of 25% per year commencing one year
from the date of grant. A total of 77.5 million shares have been reserved for
issuance under this plan, including 5 million shares approved by the
stockholders in May 2001 and 10 million approved by stockholders in May 2000.

     The Company's 1982 Incentive Stock Option Plan is administered by the Board
of Directors. Terms of that plan required that the exercise price of options be
no less than the fair value at the date of grant and that options be granted
only to employees and consultants of the Company. Generally, options granted
vested in annual increments of 25% per year commencing one year from the date of
grant and had a term of ten years. During 1992, the 1982 Incentive Stock Option
Plan expired by its terms. Accordingly, no further options may be granted
thereunder. None of the options previously granted under this plan remained
outstanding at December 31, 2001.

     In May 1995, the stockholders approved the 1995 Director Option Plan, which
replaced the 1986 Directors' Stock Option Plan, and reserved 1 million shares
for issuance thereunder. Terms of the 1995 Director Option Plan provide for an
initial option grant to new directors and subsequent automatic option grants
each year thereafter. The option grants generally have a ten-year term and vest
in equal increments over four years. The exercise price of options granted is
the fair market value of the stock on the date of grant. On May 7, 1999, the
stockholders approved an amendment to the 1995 Director Option Plan to increase
the annual grant of options to each non-employee director to 25,000 shares,
which fully vest six months after grant. None of the options previously granted
under the 1986 Directors' Stock Option Plan remained outstanding at December 31,
2001.

     In connection with the acquisition of C-Cube (see Note 2 of the Notes),
each outstanding stock option under C-Cube's Stock Option Plan was converted to
an option of the Company's common stock at a ratio of 0.79. As a result,
outstanding options to purchase 10,616,640 shares and warrants to purchase
750,100 shares were assumed. No further options may be granted under the C-Cube
Stock Option Plan.

     In connection with the acquisition of Syntax Systems, Inc. (see Note 2 of
the Notes), each outstanding stock option under Syntax's Stock Option Plan was
converted to an option of the Company's common stock at a ratio of 0.1896. As a
result, outstanding options to purchase 611,241 shares were assumed. No further
options may be granted under the Syntax Stock Option Plan.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

2001, Syntax on November 29, 2000, DataPath on July 14, 2000, Intraserver on May
26, 2000 and the merger with SEEQ on June 22, 1999. (See Note 2 of the Notes.)
The weighted average estimated grant date fair value, as defined by SFAS No.
123, of options granted during 2001, 2000 and 1999 was $15.44, $30.86 and $14.35
per option, respectively. The estimated grant date fair value was calculated
using the Black-Scholes model. The Black-Scholes model, as well as other
currently accepted option valuation models, was developed to estimate the fair
value of freely tradable, fully transferable options without vesting
restrictions, which significantly differ from the Company's stock option awards.
These models also require highly subjective assumptions, including future stock
price volatility and expected time until exercise, which greatly affect the
calculated grant date fair value. The following weighted average assumptions
were included in the estimated grant date fair value calculations for the
Company's stock option awards:

     Stock purchase plan.  Since 1983, the Company has offered an Employee Stock
Purchase Plan under which rights are granted to all employees to purchase shares
of common stock at 85% of the lesser of the fair market value of such shares at
the beginning of an offering period or the end of each six-month segment within
such an offering period. Sales under the Employee Stock Purchase Plan in 2001,
2000 and 1999 were approximately 2.9 million, 5.2 million and 4.3 million shares
of common stock at an average price of $16.39, $6.30 and $5.20 per share,
respectively. In 1997, the stockholders approved an amendment to the Company's
Employee Stock Purchase Plan to increase the number of shares of common stock
reserved for issuance on the first day of each fiscal year, beginning fiscal
1998, by 1.15% of the shares of the Company's common stock issued and
outstanding on the last day of the immediately preceding fiscal year, less the
number of shares available for future option grants under the Employee Stock
Purchase Plan on the last day of the preceding fiscal year. An additional 2.4
million, 2.5 million and 1.5 million shares were reserved for this Plan in 2001,
2000 and 1999, respectively. In addition, during 2001, the Company's
stockholders approved an amendment to the Company's Employee Stock Purchase Plan
to increase the number of shares reserved for issuance by 10 million shares.

     The weighted average estimated grant date fair value, as defined by SFAS
No. 123, of rights to purchase stock under the Employee Stock Purchase Plan
granted in 2001, 2000 and 1999 was $6.90, $13.83 and $8.30 per share,
respectively. The estimated grant date fair value was calculated using the
Black-Scholes model. The following weighted average assumptions were included in
the estimated grant date fair value calculations for rights to purchase stock
under the Company's Employee Stock Purchase Plan:

     Stock purchase rights.  In November 1988, the Company implemented a plan to
protect stockholders' rights in the event of a proposed takeover of the Company.
The plan was amended and restated in November 1998. Under the plan, each share
of the Company's outstanding common stock carries one Preferred Share Purchase
Right. Each Preferred Share Purchase Right entitles the holder, under certain
circumstances, to purchase one-thousandth of a share of Preferred Stock of the
Company or its acquirer at a discounted price. The Preferred Share Purchase
Rights are redeemable by the Company and will expire in 2008.

     Pro forma net (loss)/income and proforma net (loss)/income per share.  Had
the Company recorded compensation costs based on the estimated grant date fair
value, as defined by SFAS No. 123, for awards granted under its stock option
plans and stock purchase plan, the Company's net income and earnings per share
would have been adjusted to the pro forma amounts below for the years ended
December 31, 2001, 2000 and 1999.

</Table>

     For the year ended December 31, 2001, common stock equivalents of
approximately 95.8 million shares were excluded from the computation of pro
forma diluted earnings per share as a result of their antidilutive effect on pro
forma earnings per share. For the year ended December 31, 2000, common stock
equivalents of approximately 6.2 million shares and interest expense of $11
million, net of taxes, associated with the 2000 Convertible Subordinated Notes
were excluded from the computation of pro forma diluted earnings per share as a
result of their antidilutive effect on pro forma earnings per share. For the
year ended December 31, 1999, common equivalents of approximately 17.6 million
shares and interest expense of $8 million, net of taxes, associated with the
1999 Convertible Subordinated Notes were excluded from the computation of pro
forma diluted earnings per share as a result of their antidilutive effect on pro
forma earnings per share. The pro forma effect on net income and net income per
share for 2001, 2000 and 1999 is not representative of the pro forma effect on
net income in future years because it does not take into consideration pro forma
compensation expense related to grants made prior to 1995. See Note 8 of the
Notes for a discussion of the 2001, 2000 and 1999 Convertible Notes.

     Undistributed earnings of the Company's foreign subsidiaries aggregate
approximately $265 million at December 31, 2001, and are indefinitely reinvested
in foreign operations or will be remitted substantially free of additional tax.
No material provision has been made for taxes that might be payable upon
remittance of such earnings, nor is it practicable to determine the amount of
this liability.

</Table>

     The deferred tax assets valuation allowance at December 31, 2001 and 2000
is attributed to U.S. federal, state and foreign deferred tax assets, which
result primarily from restructuring and other one-time charges, and net
operating loss carryovers. Management believes that the realization of deferred
tax assets was not assured in the years presented other than to the extent of
estimated taxable income for the carryover period.

     At December 31, 2001, the Company had federal and state net operating loss
carryovers of approximately $242 million and $77 million, respectively, which
will expire beginning in 2004 through 2022. Approximately $39 million of the
federal net operating loss carryover and $12 million of the state net operating
loss carryover relate to recent acquisitions and are subject to certain
limitations under IRC sec.382. The Company had tax credits of approximately $25
million, which will expire beginning in 2004.

     The Company paid $22 million, $28 million and $14 million for income taxes
in 2001, 2000 and 1999, respectively.

     The IRS is currently auditing the Company's federal income tax returns for
fiscal years 1995 through 1996. Final proposed adjustments have not been
received for these years. Management believes the ultimate outcome of the IRS
audits will not have a material adverse impact on the Company's financial
position or results of operations.

NOTE 11 -- SEGMENT REPORTING

     The Company operates in two reportable segments: the Semiconductor segment
and the SAN Systems segment. In the Semiconductor segment, the Company uses
advanced process technology and comprehensive design methodologies to design,
develop, manufacture and market highly complex integrated circuits. These
system-on-a-chip solutions include both application specific integrated
circuits, commonly referred to as ASICs; application specific standard products
in silicon, or ASSPs; as well as RAID host bus adapters and related products;
and services. In the SAN Systems segment, the Company designs, manufactures,
markets and supports high-performance, highly scaleable open storage area
network systems, storage solutions and a complete line of RAID systems,
subsystems and related software. There were no significant inter-segment
revenues for the periods presented below.

NOTE 12 -- COMMITMENTS AND CONTINGENCIES

     The Company uses operating leases to finance certain equipment used in its
wafer fabrication facilities. As of December 31, 2001 the Company had two
operating leases, which are commonly referred to as synthetic leases. A
synthetic lease represents a form of off-balance sheet financing under which an
unrelated third party funds up to 100% of the costs of acquisition and
installation of the property.

     In March 2000, the Company entered into a master lease and security
agreement with ABN AMRO Bank and two other banks acting as the Lessor and
several other banks acting as Participants for up to $250 million for certain
wafer fabrication equipment. Each lease supplement pursuant to the transaction
will have a lease term of three years with two consecutive one-year renewal
options. The Company may, at the end of any lease term, return, or purchase at a
stated amount all the equipment. As of December 31, 2001, the Company had fully
drawn against the agreement.

     In April 2001, the Company entered into a master lease and security
agreement with a group of banks for up to $230 million for certain wafer
fabrication equipment. The Lessor under this lease is an unrelated trust
administered and managed by Wells Fargo Bank Northwest. Each lease supplement
pursuant to the transaction will have a lease term of five years with two
consecutive one-year renewal options. The Company may, at the end of any lease
term, return, or purchase at a stated amount all the equipment. As of December
31, 2001, the Company had drawn down a total of $152 million under the
agreement. The agreement was amended in fourth quarter of 2001 to reduce the
total availability to $180 million.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In the third quarter of 2001, the Company amended the master lease and
security agreements entered into in April 2001 and March 2000 as described
above. As of December 31, 2001, there was $296 million outstanding under these
two leases. Pursuant to the amendments, the Company now participates in these
leases as a debt holder, replacing some of the existing banks. As of December
31, 2001, the Company's debt contribution of $242 million and cash collateral of
$54 million were recorded as non-current assets. The Lessors have access to the
cash collateral only in the event of a default by the Company. Per the
amendments, the Company is required to maintain a minimum cash balance of $350
million. The Company was in compliance with this requirement as of December 31,
2001.

     No officer or employee of the Company has any financial interest with
regards to these leasing arrangements or with the trust used in the April 2001
lease. The minimum lease payments under the two lease agreements, excluding
option periods, are $3 million each for the years 2002 and 2003, and $0.9
million each in the years 2004 and 2005. These payments reflect the amendments
and as such, exclude any payments on the Company's debt participation.

     The Company leases the majority of its facilities and certain equipment
under non-cancelable operating leases, which expire through 2011. The facilities
lease agreements typically provide for base rental rates that are increased at
various times during the terms of the lease and for renewal options at the fair
market rental value. Future minimum payments under these operating lease
agreements are $34 million, $28 million, $21 million, $15 million, $9 million
and $25 million for the years ending December 31, 2002, 2003, 2004, 2005, 2006
and thereafter, respectively.

     Rental expense under all operating leases was $96 million, $64 million and
$58 million for the years ended December 31, 2001, 2000 and 1999, respectively.

     In late 1995, a lawsuit was filed by certain former shareholders of our
Canadian subsidiary ("LSI Canada") petitioner in a proceeding in the Court of
Queens Bench of Alberta, Judicial District of Calgary in which the question of
LSI Canada's value at September 7, 1995 is to be determined. At present, parties
representing approximately 580,000 shares are contesting the value of $4.00
(Canadian) that was paid to the other former shareholders of LSI Canada at the
time all the shares of LSI Canada not then owned by the Company were acquired by
the Company. Following a hearing held in March 2001, the Court dismissed the
motion of the former shareholders that challenged the proprietary of the fair
value proceedings initiated by LSI Canada and the jurisdiction of the Court to
adjudicate the matter. In addition, the Court ruled that the portions of the
application of the former shareholders to initiate a claim based upon
allegations that our actions and certain named (former) directors and a (former)
officer of LSI Canada were oppressive of the rights of minority shareholders of
LSI Canada were to be struck and the balance of the claims were stayed. The
Court also directed all of the litigants to recommence preparation for trial in
the fair value proceeding and advised the litigants of the Court's intention to
schedule a date for trial of that matter as soon as practicable. While we cannot
give any assurances regarding the resolution of these matters, we believe that
the final outcome will not have a material adverse effect on our consolidated
results of operations or financial condition. No assurance can be given,
however, that these matters will be resolved without our becoming obligated to
make payments or to pay other costs to the opposing parties, with the potential
for having an adverse effect on our financial position or results of operations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In February 1999, a lawsuit alleging patent infringement was filed in the
United States District Court for the District of Arizona by the Lemelson
Medical, Education & Research Foundation, Limited Partnership against 88
electronics industry companies, including LSI Logic. The case number is
CIV990377PHXRGS. The patents involved in this lawsuit are alleged to relate to
semiconductor manufacturing and computer imaging, including the use of bar
coding for automatic identification of articles. In September 1999, the Company
filed an answer denying infringement, raising affirmative defenses and asserting
a counterclaim for declaratory judgment of non-infringement, invalidity and
unenforceability of Lemelson's patents. In December 2001, the court held a
hearing on Cypress Semiconductor's and plaintiff's cross-motions for summary
judgment with respect to the 4,390,586 patent. In February 2002, the court
denied Cypress Semiconductor's motion for summary judgment. The court also
granted the plaintiff's cross motion in part with respect to Cypress
Semiconductor and denied the cross-motion with respect to all other defendants.
These activities are ongoing, and as yet, no trial date has been set. While the
Company cannot make any assurance regarding the eventual resolution of this
matter, the Company does not believe it will have a material adverse effect on
our consolidated results of operations or financial condition.

     U.S. Philips Corporation, a subsidiary of Royal Philips Electronics of
Netherlands, filed suits on October 17, 2001 in the U.S. District Court in New
York against eight companies, including us, for allegedly infringing and
inducing others to infringe Philips U.S. Patent Number 4,689,740. This patent is
directed to devices and methods used with the Inter-Integrated Circuit Bus.
While we cannot make any assurance regarding the eventual resolution of this
matter, we do not believe it will have a material adverse effect on our
consolidated results of operations or financial condition.

     The Company is a party to other litigation matters and claims, which are
normal in the course of its operations. While the results of such litigations
and claims cannot be predicted with certainty, the final outcome of such matters
is not expected to have a significant adverse effect on the Company's
consolidated financial position or results of operations. No assurance can be
given, however, that these matters will be resolved without the Company becoming
obligated to make payments or to pay other costs to the opposing parties, with
the potential for having an adverse effect on the Company's financial position
or its results of operations.

NOTE 13 -- SUBSEQUENT EVENTS

     On January 16, 2002, the Company announced a series of actions to reduce
costs and align company expenses to current revenues. These actions include:
restructuring the Company's manufacturing operations in Tsukuba, Japan;
divesting the CDMA handset and DSL standard product business units and reducing
the worldwide workforce by approximately 1,400 positions or 20 percent.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors
of LSI Logic Corporation:

     In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) on page 84 present fairly, in all material
respects, the financial position of LSI Logic Corporation and its subsidiaries
(the "Company") at December 31, 2001 and December 31, 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. In addition, in our opinion, the
financial statement schedule listed in the index appearing under Item 14(a)(2)
on page 85 present fairly, in all material respects, the information set forth
therein when read in conjunction with the related consolidated financial
statements. These financial statements and financial statement schedule are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements and financial statement schedule based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States of America, which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
