                                     PART I

ITEM 1.  BUSINESS

GENERAL

     Agere Systems designs, develops and manufactures integrated circuits for
use in a broad range of communications and computer systems and optoelectronic
components for communications networks. We are the world leader in sales of
communications components, which include both integrated circuits and
optoelectronic components. Communications components are basic building blocks
of electronic and photonic products and systems for terrestrial and submarine,
or undersea, communications networks and for communications equipment.

     In fiscal 2001, we had two principal businesses: Integrated Circuits and
Optoelectronics. Integrated circuits, or chips, are made using semiconductor
wafers imprinted with a network of electronic components. They are designed to
perform various functions such as processing electronic signals, controlling
electronic system functions and processing and storing data. Our Integrated
Circuits business also includes our wireless local area networking products,
which facilitate the transmission of data and voice signals within a localized
area without cables or wires. Our Optoelectronics business includes our
optoelectronic components operations, including both our active optoelectronic
and our passive optical components. Optoelectronic components transmit, process,
change, amplify and receive light that carries data and voice traffic over
optical networks. The Integrated Circuits and Optoelectronics businesses each
include revenue from the licensing of intellectual property related to that
business.

     On July 20, 2000 Lucent Technologies announced that it planned to create a
separate company that comprised its microelectronics business including its
integrated circuits and optoelectronics divisions. We were incorporated in
Delaware on August 1, 2000 to be that company. Our separation from Lucent was
substantially completed, including the transfer of all assets and liabilities
related to these divisions other than pension and postretirement plan assets and
liabilities, which have yet to be transferred, when we completed our initial
public offering in April 2001. As of December 1, 2001, Lucent owned 100% of our
outstanding Class B common stock and 37 million shares of our outstanding Class
A common stock, which represented a majority of the combined voting power of
both classes of our common stock. Lucent has announced that it continues to move
forward with its intention to distribute all shares of our common stock that it
owns to its stockholders in a tax-free distribution, but Lucent's credit
facilities include conditions that must be met before Lucent can distribute its
Agere stock to its stockholders. See "Item 7 -- Overview -- Separation from
Lucent" for further information about our spin off as a fully independent
company.

     Our principal executive offices are located at 555 Union Boulevard,
Allentown, Pennsylvania 18109. Our telephone number is (610) 712-4323. Our World
Wide Web site address is www.agere.com.

     We sell our products primarily through our direct sales force, but we also
utilize distributors, resellers and electronic commerce. Of our total net
revenue of $4,080 million in the fiscal year ended September 30, 2001,

                                        2
<PAGE>

$2,869 million or 70% was generated by our Integrated Circuits segment and
$1,211 million or 30% was generated by our Optoelectronics segment.
Approximately 45% of our revenue was generated in the United States and 55%
internationally. See note 17 to our financial statements in Item 8 for further
information about our Integrated Circuits and Optoelectronics segments.

     As of September 30, 2001 we employed approximately 14,400 people worldwide.
We have major research and development and manufacturing sites in the United
States, Mexico, Singapore and Thailand.

INTEGRATED CIRCUITS

     We offer integrated circuits for use in a broad range of communications
networks and computer systems. Our integrated circuits are used primarily in the
following types of equipment:

     - network communications equipment, which facilitates the transmission,
       switching and management of data and voice traffic within communications
       networks;

     - client access and network connectivity devices, such as modems and analog
       line cards, which allow computers, servers and other equipment to connect
       to communications networks;

     - wireless terminals and infrastructure, such as mobile telephones and
       cellular base stations, which transmit and receive data and voice
       communications through radio waves; and

     - hard disk drives, which store data and are found in products such as
       personal computers, servers and new consumer devices.

     We also sell wireless local area networking products, which facilitate the
transmission of data and voice signals within a localized area without cables or
wires.

  STRATEGY

     Our integrated solutions combine a number of functions into a single unit.
Because of this integration, we have the ability to deliver products that
interact more effectively and enhance performance. This allows our customers to
meet the requirements of their end customers faster and more cost effectively
than if they purchase a number of separate integrated circuits.

     We have dedicated engineering groups that develop core manufacturing
technology, common design methodology and commonly used integrated circuit
design elements for use across our Integrated Circuits segment. By using common
core technologies, we simplify our design methods, create reusable intellectual
property and achieve manufacturing efficiencies.

     We believe the primary considerations for customers selecting integrated
circuit products are:

     - design capabilities, including the ability to deliver integrated
       solutions;

     - performance, as measured by speed, power requirements and reliability;

     - feature set;

     - price;

     - flexibility, which refers to the ability to design products using the
       manufacturer's own intellectual property, the manufacturer's customers'
       intellectual property or a combination of both; and

     - compatibility with other products and communications standards used in
       communications networks.

     We focus our product development and sales efforts to address the customer
considerations listed above. The relative importance of these factors may vary
depending on the product group or the particular customer's requirements. For
example, price may be one of the most important considerations for a customer
selecting many of our client access and network connectivity integrated circuits
because these integrated circuits are used in price sensitive products sold to
consumers. On the other hand, a customer selecting our network

                                        3
<PAGE>

communications integrated circuits typically will be more focused on design and
performance rather than price because these customers often have specialized
demands that require customized solutions.

  PRODUCTS AND APPLICATIONS

     Our integrated circuits support five primary applications: network
communications equipment, client access and network connectivity devices,
wireless products, wireless local area networking products, and storage and
analog products.

  Network Communications Equipment

     We offer integrated circuits that facilitate the transmission and switching
of data and voice signals within communications networks. Our integrated
circuits process signals and transmit the signals to deliver information
throughout the network. Our integrated circuits are key building blocks in both
optical and wireline communications networks.

     We sell a complete integrated circuit solution that supports speeds up to
2.5 gigabits per second. This solution consists of physical layer devices,
integrated circuits supporting SONET/SDH communication standards, multi-service
switching fabrics and network processing devices and broadband access devices,
each of which is described below. We have, in various stages of development, 10
gigabits per second products that have either recently been introduced in
commercial quantities or are currently being sampled by one or more customers.

     Physical Layer Devices.  High-speed physical layer devices are key elements
in the conversion between optical signals and electronic signals, as required by
communications networks. High-speed physical layer devices accept the output
from an optical receiver and convert it into a digital data signal that can be
used in communications switching and processing functions. Our products include
a set of six integrated circuit components for physical layer devices that
provide a complete product offering for 10 gigabits per second transmission. We
offer our customers physical layer device components either separately or
together with optoelectronic components. In particular, we sell a transponder
which combines our physical layer device components together with our
optoelectronic components in a single product.

     SONET/SDH Network Devices.  Synchronous optical networks, which are
typically referred to as SONET, and synchronous digital hierarchy standard, or
SDH, carry data, voice and video traffic through a network by combining lines
carrying traffic at slower speeds with lines carrying traffic at higher speeds.
This process is known as multiplexing, and involves directing traffic from the
individual lines into designated time slots in the higher speed lines, and those
lines into still higher speed lines. The SONET/SDH equipment that handles the
directing of traffic into slower speed and faster speed lines is the add-drop
multiplexor, or ADM. Add-drop multiplexors handle the addition and removal of
traffic from a SONET/SDH communication transmission. We offer single-chip
integrated circuit solutions, or framers, for add-drop multiplexing of data and
voice traffic. In addition, our framers are used in high-speed routers within an
optical network. A router is an interface, or link, between two networks.

     Multi-Service Switching Fabrics and Network Processing Devices.  Switching
devices guide data to different local area networks and wide area networks based
on the intended destination. Multi-service switching devices support the
transmission of voice and video signals as well as data. We sell switch fabrics
and network processors to communications equipment manufacturers. A switch
fabric directs the data within a switching device. A network processor is a
component that controls how data is sent over a network or over a switch fabric
such that the data retains its quality of service without interfering with other
data traffic. We also offer supporting software with our switching products. In
addition, our customers sometimes add their own supporting software to switch
fabrics and network processors that they purchase from us to produce complete
switching equipment.

     We currently offer switching products for asynchronous transfer mode, or
ATM. We are developing switching products for the Internet protocol standard.
These products are being sampled by some customers but further design work is
required before they will be available for sale in commercial quantities.

                                        4
<PAGE>

Asynchronous transfer mode and Internet protocol refer to different procedures
for the formatting and timing of data transmission between two pieces of
equipment. Our switching integrated solutions reduce the number of required
integrated circuits needed in a switching device.

     Broadband Access Devices.  Broadband is a general term which refers to
high-speed data transmission. Our broadband access integrated circuits, or
mappers, support data transport between central offices and enterprise sites by
aggregation and termination. Aggregation refers to the combining of many
low-speed, or tributary, data signals from enterprises into higher speed, or
trunk, data signals for transmission to a central office. Termination refers to
the separation of trunk data signals into lower-speed, tributary data signals.

     Our products support data transport for T-carrier data transport in North
America. T-carrier is a digital transmission service from a common carrier. We
support similar services worldwide which are referred to as J-carrier in Japan
and E-carrier in Europe. T-carrier services such as T1 and T3 lines are widely
used to create point-to-point networks for use by enterprises. T1 and T3 lines
refer to different levels of T-carrier service which transmit data at 1.5
megabits per second and 44.7 megabits per second, respectively. A megabit is a
unit of measurement for data and is equal to one million bits.

     Customized Solutions.  The majority of our revenue from our network
communications products is derived from the manufacture of customized integrated
circuits for our customers. These integrated circuits incorporate our
intellectual property or combine our intellectual property with our customers'
intellectual property to create a customized solution for these customers. For
some customers, we design and manufacture the integrated circuit while the key
intellectual property belongs solely to our customers. We draw our intellectual
property from the various product areas described above in order to meet our
customers' specific requirements.

     We also deliver customized solutions with our field-programmable gate
arrays, or FPGAs, or our field-programmable systems-on-a-chip, or FPSCs. Our
field-programmable gate array is a specialized processor of electronic signals
that can be modified by a customer for a number of functions after the
integrated circuit has been deployed in a network. Our field-programmable
system-on-a-chip incorporates several complex functions as well as a
field-programmable gate array on one integrated circuit. On December 7, 2001, we
entered into an agreement with Lattice Semiconductor Corporation to sell our
FPGA and FPSC business for $250 million in cash. We expect this transaction to
be completed in the second quarter of fiscal 2002, subject to regulatory
approval and other customary closing conditions.

     Our systems-level knowledge allows us to turn our customers' design
concepts into a systems solution quickly and effectively. Our intellectual
property gives our customers the flexibility to customize their products to meet
their individual cost and performance objectives.

  Client Access and Network Connectivity Devices

     We sell integrated circuits for use in products that allow users to access
communications networks through a variety of different methods. We offer our
customers solutions that include integrated circuits and software.

     Many of our products convert analog signals into digital signals and
digital signals into analog ones. Analog refers to a transmission technique
employing a continuous signal that varies in amplitude, frequency or phase of
the transmission. Digital, on the other hand, refers to a method of storing,
processing and transmitting data that uses distinct electronic or optical pulses
to represent the binary digits 0 and 1.

     We sell integrated circuits as part of the following client access and
network connectivity products:

     Modem Products.  We primarily sell our integrated circuits for modem
products directly to leading manufacturers of personal computers and other
electronic equipment as well as to manufacturers who sell modem solutions to
manufacturers of personal computers.

     Input/Output Products.  Input/output refers to the transfer of data within
and between computers, peripheral equipment, such as printers, scanners and
digital cameras, and data networks. We sell input/output

                                        5
<PAGE>

products primarily to manufacturers of computers, peripheral equipment and
communications equipment. A majority of our sales are customized solutions that
combine our intellectual property with that of our customers in the design of
our integrated circuits. Our products support Universal Serial Bus, or USB, and
IEEE-1394 industry standards, which are both established connectivity and
transmission standards. We also are currently developing solutions that utilize
InfiniBand(TM), a new industry standard for high-bandwidth input/output
operations for enterprise computing. We have started to sell our first
InfiniBand product.

     Analog Line Card and Analog Telephone Products.  Traditional voice
telephone equipment uses technology in which voice communications are
transmitted as analog signals until they reach a network services provider's
central office, where analog line cards are located. Analog line cards convert
analog voice signals into digital signals to be transmitted through the
communications network and convert the digital signal coming from the network
back to analog in order to complete the telephone call. Our customers also use
our products in telephone interfaces, or lines, located closer to an end user in
devices such as television set-top boxes, broadband gateways and integrated
access devices. Broadband gateways and integrated access devices combine a
variety of communications technologies such as analog and digital subscriber
line in the end user's premises onto a single telephone line for transmission to
the network. We sell our analog line card and telephone solutions to
manufacturers of communications equipment for use worldwide.

     Traditional Voice Systems.  We provide integrated circuits to
telecommunications equipment manufacturers for use in traditional voice
telephone networks and integrated services digital network, or ISDN, systems.
These networks are not as advanced as newer voice and data networks that
manufacturers of communications equipment currently offer. We expect sales for
these systems to decline rapidly over the next several years.

     Newly Introduced Products.  We have started to sell products in areas for
which, if sufficient demand emerges, we expect to expand our offerings. We have
started to offer integrated circuits and software for use in digital telephony
products. Digital telephony products are solutions that access and interface
with merged voice and data networks. We also have introduced a series of
asynchronous transfer mode interconnect products for use in infrastructure
equipment for digital telephony services. Asynchronous transfer mode, or ATM,
refers to a specific set of procedures for the formatting and timing of data
transmission between two pieces of equipment. We sell our digital telephony
solutions to manufacturers of business telephone equipment.

  Wireless Products

     We sell integrated circuits for use in digital mobile telephones, cellular
base stations and other wireless data and voice communications products. We also
offer supporting software as part of our comprehensive integrated circuit
wireless product solutions. These solutions include:

     - digital signal processors for speech compression and encoding and
       transmission of voice and data;

     - radio frequency integrated circuits to transmit and receive signals;

     - conversion signal processors to convert signals between frequencies used
       in digital signal processors and frequencies used for radio transmission;
       and

     - software that controls the communication process.

     We also have started to license hardware and software designs for mobile
telephones that use our integrated circuits.

     Most of our wireless products operate on the Global Systems for Mobile
Communications, or GSM, standard. We also sell products that support General
Packet Radio Service, or GPRS, that provide enhanced data transmission
capabilities for GSM mobile phones.

     Wireless Infrastructure Products.  We sell integrated circuit solutions
used in wireless infrastructure products, which are primarily cellular base
stations and cellular base transceiver stations, and wireless terminals, which
include mobile telephones, pagers and personal digital assistants.

                                        6

  Wireless Local Area Networking Products

     We sell integrated circuits, software and equipment for wireless networks.
We offer our ORiNOCO(TM) products for wireless local area networking and
Bluetooth(TM) products for personal area networking.

     ORiNOCO Products.  Our ORiNOCO products comprise a complete wireless local
area network system that provides broadband network access through mobile and
fixed data devices. We offer the software and equipment necessary to create and
support wireless local area networks, which are typically referred to as
wireless LANs. Our wireless local area network solution currently supports data
transmission speeds of over 10 megabits per second. We sell a complete solution
for wireless networking that facilitates mobile Internet connectivity to the end
user in an enterprise, home or public space, such as an airport lounge or hotel
lobby.

     We sell wireless local area network solutions to network services providers
and to customers that sell to enterprises and home users under the ORiNOCO
brand. We also sell our ORiNOCO products to personal computer manufacturers that
integrate them into their products. Our primary indirect channel into the
enterprise market is Avaya Inc., formerly the enterprise networks group of
Lucent.

     Bluetooth Products.  We sell integrated circuit solutions and supporting
software for the new market of Bluetooth technology applications. Bluetooth is
an open standard for short-range radio transmission of digital voice and data
that facilitates a wireless personal area network. The Bluetooth technology also
makes it easier for data synchronization of mobile computers, mobile telephones
and handheld devices. Bluetooth uses radio waves that can pass through walls and
other non-metal barriers to create a personal area network.

     We have started to sell a two-component Bluetooth solution and supporting
software. Our solution facilitates a wireless personal area network which
supports data transmission speeds of up to 1 megabit per second for devices
within an approximately 30-foot radius. We sell our Bluetooth products to
manufacturers of communications and computer equipment.

  Storage and Analog Products

     We sell integrated circuits for use in storage devices, commonly referred
to as hard disk drives. As applications used on computers and communications
equipment become more complex, we expect an increased demand for higher storage
capability. We also sell integrated circuits for use in analog signal processing
and control functions within various products. Analog integrated circuits shape
or condition electronic signals and amplify electronic signal strength. They
also regulate voltage levels and provide interfaces between products within an
analog environment. We currently focus on development opportunities in the hard
disk drive product area, the analog communications product area and in the
product area for analog power products, which regulate power.

OPTOELECTRONIC COMPONENTS

     Our optoelectronic components are utilized in optical networks. Optical
networks transmit information as pulses of light, or optical signals, through
optical fibers, which are hair-thin glass strands. An optical network utilizes a
number of interdependent active optoelectronic and passive optical components.
An active component is a device that has both optical and electronic properties.
A passive component is a device that functions only in the optical domain. We
primarily offer active optoelectronic components, including:

     - lasers, which are devices that produce light suitable for optical

       optoelectronic components in one unit that transmits and receives optical
       signals; and

     - micro electro-mechanical systems, or MEMS, which are small mechanical
       products that perform a variety of optical functions without converting
       an optical signal into electronic form. Our MEMS products are being
       sampled by some customers but further design and manufacturing process
       development will be required before these products will be available for
       sale in commercial quantities.

In addition to our broad portfolio of active optoelectronic components, we have
started to sell passive optical filters and silicon waveguides. Passive optical
filters are devices used in conjunction with active optoelectronic components in
products such as amplifiers. Silicon waveguides are passive optical components
that manipulate optical signals to perform a variety of functions.

     We sell our optoelectronic components for use in submarine and terrestrial
optical networks. Submarine networks transmit optical signals undersea, usually
at high speeds and over long distances. Terrestrial networks include high-speed
transport networks, which transmit optical signals at high speeds over long
distances, and metropolitan networks, which transmit optical signals between
central offices of network services providers or between enterprises and central
offices. Terrestrial networks also include cable television networks, which
transmit optical signals between cable system operators and homes, and data
communication networks, which transmit optical signals within a local area
network. A local area network links data devices such as servers, computers and
printers in the same localized area to facilitate Internet access and to share
files and programs.

  STRATEGY

     We believe the primary considerations for customers selecting
optoelectronic components are:

     - performance, as measured by speed, power requirements and reliability;

     - price;

     - breadth of product line and ability to offer integrated solutions;

     - quality and automation of manufacturing processes;

     - manufacturing capacity, as measured by ability to satisfy orders; and

     - compatibility of products with other products and communications
       standards used in communications networks.

     Our optoelectronic components are engineered to work together in an optical
network. We sell integrated solutions that combine multiple components into a
single product. We believe our integrated solutions allow our customers to
reduce the size and costs of their optical network equipment and reduce their
time to develop new products. We also believe these solutions allow our
customers to rely on a smaller number of suppliers and improve the performance
of their products.

  PRODUCTS AND APPLICATIONS

     We have described below our key optoelectronic components and the network
applications for these products.

  Key Optoelectronic Components

     Lasers.  We offer a variety of types of lasers for use in high-speed
transport, metropolitan, cable television and submarine network applications.
Higher power lasers can transmit light greater distances than lower power
lasers. A single laser is required for each channel in a dense wavelength
division multiplexing, or DWDM, system, which is a system that transmits two or
more signals over a single optical fiber. Communications equipment manufacturers
use different types of lasers depending on the needs of the specific network
application.

                                        8
<PAGE>

     Modulators.  Modulation can be achieved directly by turning a laser on and
off or by external modulators that transmit or interrupt a continuous optical
signal to achieve the same on and off effect. Long-distance and submarine
networks typically use high power lasers and external modulators, while
short-distance networks use direct modulation. Our lithium niobate modulators
are used in high-speed transport and metropolitan network applications, and our
lithium niobate polarization controllers are used in high-speed transport
network applications.

     Amplifiers.  During transmission, an optical signal must be periodically
renewed because it loses its strength as it travels within the network. Optical
amplifiers increase the strength of an optical signal without converting it back
into an electronic signal. Optical amplifiers represent a major cost efficiency,
as network services providers can reduce the number of costly
optical-to-electronic-to-optical conversions. We offer erbium doped fiber
amplifiers and raman amplifiers in high-speed transport and metropolitan network
applications.

     Transmitters, Receivers and Transceivers.  We offer cooled laser
transmitters for high-speed transport, metropolitan and cable television network
applications, uncooled laser transmitters for metropolitan network applications,
and turnable laser transmitters for high-speed transport network applications.
Our positive intrinsic negative, or PIN, receivers are used for high-speed
transport, metropolitan and cable television network applications, and our
avalanche photo detector, or APD, receivers are used for high-speed transport
and metropolitan network applications. Transmitters and receivers are also
sometimes combined into one module, which is called a transceiver.

     Transponders.  Our transponders offer both integrated circuits and
optoelectronic components in one combined unit, or module. This module combines
a transceiver with a multiplexor/demultiplexor into a unified product. A
multiplexor is an electronic device that allows two or more signals to be
combined for transmission over one communications circuit. A demultiplexor
separates two or more signals previously combined by compatible multiplexing
equipment. Our transponders are capable of multiplexing 16 electronic signals
into one optical signal. Our transponders are also capable of demultiplexing one
optical signal into 16 electronic signals. We have recently begun shipping our
2.5 gigabits per second transponders in commercial quantities to our customers
and we are sampling 10 gigabits per second transponders.

     MEMS Devices.  We recently introduced optical cross connects and dynamic
gain equalizers, which are our first optical micro electro-mechanical systems,
or MEMS, devices. MEMS are small mechanical products that perform a variety of
optical functions which include optical switching, dynamic gain equalization and
add-drop multiplexing. An optical cross connect is an optical switching device
that maintains the optical signal as light from input to output, without
converting it into electronic form. A dynamic gain equalizer is an optical
device that optimizes transmissions in an optical network by equalizing the
amplitude of specific wavelengths of light within the optical fiber. These
products are being sampled by some customers but further design and
manufacturing process development is required before they will be available for
sale in commercial quantities.

     Thin Film Optical Filters.  Thin film optical filters are designed to allow
only selected wavelengths of light to pass through them. Our filters are
manufactured by depositing many thin layers on a base of specially made glass.
Thin film optical filters are used in dense wavelength division multiplexing, or
DWDM, systems, which are systems that transmit two or more signals over a single
fiber. They can also be used to correct the amplitude of the signal coming from
an optical amplifier. Our thin film optical filters are generally sold to
optical component manufacturers which package and combine them with active
optoelectronic components.

     Silicon Waveguides.  We have started to sample optical dynamic gain
equalizers, which are our first silicon waveguide products. We believe our
experience in silicon-based integrated circuit manufacturing processes is an
important factor in our ability to manufacture these products. These
silicon-based processes will permit production of these products in high
volumes. In addition, silicon-based technology allows active components such as
transmitters and receivers to be integrated with silicon waveguides, permitting
reductions in size and cost of integrated modules.

  Network Applications

     Submarine.  We offer a variety of highly reliable, ultrastable components
designed to withstand the rigors of long-distance undersea transmission.
Customers for our submarine products are manufacturers of undersea
communications equipment.

     High-Speed Transport.  Our products support transmission of optical signals
at speeds of 2.5 or 10 gigabits per second. We also have 40 gigabits per second
modulators and receivers that are currently being sampled by customers. Our
high-speed transport products can send multiple optical signals for distances up
to 720 kilometers without amplification, and much further when used in
conjunction with optical amplifiers. Customers for our high-speed transport
products are manufacturers of communications equipment who sell to network
services providers that operate long-distance communications networks.

     Metropolitan.  We sell optoelectronic components that are used in optical
networks in metropolitan areas to carry information between central offices of
network services providers or between large enterprises and central offices. The
information transmitted within these networks is carried for shorter distances,
generally 40 kilometers or less, and at lower speeds than those used in
high-speed transport network applications. We sell products designed for
metropolitan communications networks to manufacturers of communications
equipment, which sell to service providers that operate local exchanges and to
manufacturers of network equipment for enterprises.

     Cable Television.  Over the past ten years, cable system operators have
upgraded their networks to add optical fiber to their networks. Our cable
television optoelectronic components provide a high-speed return path from the
consumer's home to the cable system operator. This return path allows cable
system operators to offer Internet and telephone services, in direct competition
with network services providers. Customers for our cable television
optoelectronic components are manufacturers of cable television transmission
equipment.

     Data Communication.  A local area network links data devices such as
servers, computers and printers in the same localized area to facilitate
Internet access and to share files and programs. As bandwidth and transmission
distance requirements of enterprises have increased, it has become more
practical to utilize the superior transmission capabilities of optical networks
to build high-speed local area networks. These networks require transceivers to
convert electronic signals into optical signals and back into electronic signals
at high speeds. Customers for our data communication optoelectronic components
are manufacturers of network equipment for enterprises.

CUSTOMERS, SALES AND DISTRIBUTION

  CUSTOMERS

     We have a globally diverse base of customers, consisting primarily of
manufacturers of communications and computer equipment. We generally target as
customers the leaders in the market segments in which our products are used as
well as the companies we believe will be future leaders in these segments. In
fiscal 2001, we sold our products directly to approximately 250 end customers
and indirectly, through distributors, to approximately 1,000 end customers. For
some end customers, we deliver the product to, and are paid by, a third party
associated with the customer, such as their contract manufacturer. Our top 20
end customers in fiscal 2001, based on revenue, accounted for approximately 70%
of our revenue and our top 10 end customers in fiscal 2001, based on revenue,
accounted for approximately 53% of our revenue. Our top ten end customers in
fiscal 2001 were:

<Table>
<S>                   <C>
Apple Computer, Inc.  Lucent Technologies Inc.
Alcatel               Maxtor Corp.
Avaya Inc.            Nortel Networks Corp.
Cisco Systems, Inc.   Seagate Technology, Inc.
Globespan Inc.        Tycom (US) Inc.
</Table>

     All of the customers listed above purchased integrated circuits from us.
Alcatel, Avaya, Cisco Systems, Lucent, Nortel and Tycom also purchased
optoelectronic components from us. Our sales to Lucent

                                        10
<PAGE>

represented 14.9%, 21.3% and 25.7% of our revenue for fiscal 2001, 2000 and
1999, respectively. No other customer accounted for 10% or more of our revenue
in fiscal 2001, 2000 or 1999.

  SALES AND DISTRIBUTION

     We have a worldwide sales organization with approximately 500 employees as
of September 30, 2001, located in 24 domestic and 16 international sales
offices. We sell our products globally primarily through our direct sales force.
To complement our direct sales force, we also sell our products through
distributors, which sales in fiscal 2001 represented approximately 8% of our
revenue. During fiscal 2001, we discontinued our prior practice of using
manufacturers' representatives as part of our selling effort.

     When selling both our integrated circuits and optoelectronic components, we
aim to have our customers incorporate our products into the end products they
design and develop. Typically, manufacturers of communications and computer
equipment conduct a competitive process to select suppliers for the parts that
they will include in their end products. Our sales, marketing and technical
personnel work with customers to demonstrate our products' ability to satisfy
any specific requirements. We call winning the competitive process a design win.
A design win is important because it allows us to establish a long-term
relationship with the customer, at least through the life-cycle of the product.
We generally do not, however, enter into written agreements with our customers
after achieving a design win. A customer could terminate our relationship or
discontinue developing the product. Most of our revenue originates from sales
that are the result of design wins.

     After we achieve a design win and negotiate the terms of the sale, we
deliver our products to our end customers in a number of ways. Our end customers
typically have us ship our products to their facilities directly. In some
instances, however, our customer uses a contract manufacturer to manufacture and
assemble their end product. When our product is being incorporated into an end
product being manufactured by a contract manufacturer, we often ship our product
directly to the contract manufacturer and receive payment from that contract
manufacturer. To determine our sales to particular customers, however, we
recognize this type of transaction as a sale to, and revenue from, the end
customer. Sometimes a customer for which we have achieved a design win will have
us sell that product to a distributor or trading company from which they buy our
product. We recognize these transactions as indirect sales.

MANUFACTURING AND SUPPLIES

  MANUFACTURING

     Our manufacturing operations are organized in two distinct groups:
integrated circuit and optoelectronic component manufacturing. Due to increasing
overlap of our products and manufacturing processes, we have started to
integrate our manufacturing operations, where appropriate, to improve
operational efficiencies.

  INTEGRATED CIRCUIT MANUFACTURING

     We had seven facilities located in four countries devoted to manufacturing
integrated circuits as of September 30, 2001. These sites utilized approximately
2.3 million square feet. As part of our announced restructuring activities, we
are in the process of closing approximately 90,000 square feet of this space. As
of September 30, 2001, we had approximately 5,950 employees devoted to
integrated circuit manufacturing. During fiscal 2001, our company-owned and
joint venture wafer fabrication was done in the United States, Spain and
Singapore, while our assembly and test operations were in the United States,
Singapore and Thailand.

     Currently, we manufacture most of our integrated circuits in facilities
that we either own or operate through a joint venture. We also have third-party
manufacturing relationships to improve our manufacturing efficiency and
flexibility and to allow us to focus on manufacturing and developing leading
products. We entered into a joint venture with Chartered Semiconductor
Manufacturing Ltd. in December 1997 to open an integrated circuit manufacturing
facility in Singapore. Under the terms of our agreement with Chartered
Semiconductor, we agreed to purchase 51% of the production output from this
facility and Chartered

                                        11
<PAGE>

Semiconductor agreed to purchase the remaining 49% of the production output. For
more information regarding our joint venture with Chartered Semiconductor,
please see "-- Strategic Relationships -- Manufacturing Relationship." In the
future, we expect to increase the amount of integrated circuits we buy at market
prices, whether through our relationship with Chartered Semiconductor or other
strategic relationships.

     We have implemented sophisticated logistics and planning systems and
manufacturing processes that allow us to manufacture and deliver our integrated
circuits more quickly and reliably. The sophisticated internal systems we are
implementing allow us to start manufacturing a customer's specific order for
some integrated circuits within hours of receipt. Today, we believe we are able
to manufacture silicon wafers faster than most of our competitors. However, as
we increase our percentage of wafer fabrication manufactured through strategic
relationships, we may not be able to maintain our manufacturing cycle times. We
assemble, test and ship our integrated circuits, on average, in approximately
two and a half days, which we believe is better than the industry average. We
intend to continue performing these activities for substantially all of our
integrated circuits in the future and to maintain our industry-leading cycle
time.

  OPTOELECTRONIC COMPONENT MANUFACTURING

     We had six facilities located in the United States and one facility located
in Mexico devoted to manufacturing optoelectronic components as of September 30,
2001. These sites utilized approximately 700,000 square feet. As part of our
announced restructuring activities, we have closed two sites in the United
States. As of September 30, 2001, we had approximately 1,650 employees devoted
to optoelectronic component manufacturing. Currently, we manufacture
substantially all of our optoelectronic components internally. A small
percentage of our components, however, are sent to sub-assembly manufacturers.
These are manufacturers that add some pieces to the unfinished product and send
the unfinished product back to us. In these cases, we complete the manufacturing
of the final product and deliver the product to our customers.

     We intend to explore opportunities to increase our manufacturing
capabilities through joint ventures or strategic relationships with third
parties. If we form these ventures or develop these relationships, we will seek
to ensure consistent quality so that neither our customers nor our customers'
end users can differentiate between products that are manufactured in-house and
those that are not. Additionally, we have started to manufacture some of our
silicon-wafer-based optoelectronic components in our integrated circuit
facilities to capture economies of scale. This allows us to apply our extensive
experience in integrated circuit manufacturing to the high-volume manufacturing
of optoelectronic components.

     We have automated the manufacturing of core technologies used in our
optoelectronic components. In particular, we have automated our optical
sub-assembly manufacturing process, which is the core technology used in all of
our laser-based optoelectronic products. The benefits of automation include:

     - greater volume;

     - improved quality and reliability;

     - reduced costs; and

     - improved speed in responding to customer demands.

  SUPPLIES

     At times, the integrated circuits and optoelectronic components industries
have been supply constrained, meaning that demand for components is greater than
the ability of most manufacturers of integrated circuit and optoelectronic
components products, including us and our competitors, to supply products. In
early fiscal 2001, we experienced shortages in supplies of parts for our
products and in the equipment needed to increase the capacity of our
manufacturing plants, although by the end of fiscal 2001, we were not
experiencing shortages. Also, there is a limited number of qualified engineers
with the talent to develop and manufacture new products as quickly as desired. A
significant price increase from our suppliers may cause our gross profit to
decline if we could not pass the increase to our customers. The loss of a
significant supplier or the inability

                                        12
<PAGE>

of a supplier to meet performance and quality specifications or delivery
schedules may cause our revenue to decline.

     We currently purchase several different parts that are used in our
optoelectronic components for which there is only one qualified manufacturer of
each part. Some of these single source suppliers also are competitors of ours.
These parts are included in our optical amplifiers, pump lasers used in
submarine networks, lithium niobate modulators and PIN and APD receivers. The
number of qualified alternative suppliers for our single source parts and
processes is limited and the process of qualifying new suppliers requires a
substantial lead time. Although we have not experienced any significant
difficulties in obtaining the above parts or manufacturing processes, we are
currently looking for alternative sources of these parts and processes, either
through internal development or alternative suppliers.

COMPETITION

     We compete in the integrated circuit and optoelectronic component market
segments within the communications component industry. These market segments are
intensely competitive, and are characterized by:

     - rapid technological change;

     - evolving standards;

     - short product life cycles; and

     - price erosion.

     The number of competitors has risen in the past few years. We expect the
intensity of competition in the market segments we serve to continue to increase
in the future as existing competitors enhance and expand their product offerings
and as new participants enter these market segments. Increased competition may
result in price reductions, reduced revenues and loss of market share. We cannot
assure you that we will be able to compete successfully against existing or
future competitors. Some of our customers and companies with which we have
strategic relationships also are, or may be in the future, competitors of ours.

     The size and number of our competitors vary across our product areas, as do
the resources we have allocated to the segments we target. Therefore, many of
our competitors have greater financial, personnel, capacity and other resources
than we have in a particular market segment or overall. Competitors with greater
financial resources may be able to offer lower prices, additional products or
services or other incentives that we cannot match or offer. These competitors
may be in a stronger position to respond quickly to new technologies and may be
able to undertake more extensive marketing campaigns. They also may adopt more
aggressive pricing policies and make more attractive offers to potential
customers, employees and strategic partners. These competitors may make
strategic acquisitions or establish cooperative relationships among themselves
or with third parties to increase their ability to gain market share. Further,
some of our competitors are currently selling commercial quantities of products
that we are sampling to our customers, that are still in the initial stages of
development or that we may develop in the future. By being able to offer these
products in commercial quantities before we do, our competitors can establish
significant market share, acquire design wins in customer equipment programs and
create a market position that we may be unable to overcome once we have
completed development and testing of that product. Because we have a unionized
workforce and many of our main competitors are not unionized to the same extent
or at all, our product costs may be higher. As a result, our competitors may be
more profitable or may be able to compete for customers more effectively based
on price. In the event of a union work stoppage at our facilities, we may be
adversely affected.

     While we are the world leader in sales of communications components, our
competitive position varies depending on the market segment and product areas
within these segments. For example, we are number one or two, based on revenue,
in many of our product areas, including the analog modem, baseband integrated
circuits for wireless infrastructure, SONET/SDH integrated circuits and wired
communications integrated circuits. However, our competitive position is not as
strong in the wireless terminal and passive optical component product areas.
While improving our position in many of the product areas where our position is
less well-established is an objective of ours, we cannot assure you that we will
be able to accomplish this goal. Further, because we expect to face increasing
competitive pressures from both current and future competitors in the product
areas we serve, we may not be able to maintain our position in the product areas
in which we are currently a leader.

     We believe the following factors are the principal methods of competition
in our industry:

     - performance and reliability;

     - price;

     - compatibility of products with other products and communications
       standards used in communications networks;

     - product size;

     - ability to offer integrated solutions;

     - time to market;

     - breadth of product line;

                                        14
<PAGE>

     - logistics and planning systems; and

     - quality of manufacturing processes.

     While we believe we are competitive on the basis of all the above listed
factors, we believe some of our competitors compete more favorably on the basis
of price and on delivering products to market more quickly. However, we feel we
are particularly strong in offering integrated solutions, our broad product
lines and our logistics and planning systems.

RESEARCH AND DEVELOPMENT

     Our research and development personnel focus on product and manufacturing
process development, which provides the technological basis for our commercial
products, and on basic research, which helps provide the scientific advances
which ultimately lead to new products and technology and manufacturing
processes. Our product and process development team is comprised of
approximately 2,700 development engineers and scientists. Approximately
two-thirds of these development engineers and scientists work directly in our
business units to design and implement product solutions. The remaining
one-third work primarily on manufacturing and design technology that spans large
segments of our business, such as the technology for system-on-a-chip and
high-performance optical modules.

     Our basic research effort is organized into three areas:

     - optoelectronics;

     - electronic devices; and

     - circuits and systems.

     Our researchers perform application-focused research, primarily around
optical communications, semiconductor technology and advanced circuit and
systems development for future communications technologies. Across each of the
areas, we also focus on products that seek to combine our integrated circuit and
optoelectronic capabilities. We believe that the combination of our integrated
circuits and optoelectronic components may offer our customers several benefits,
including improved product performance and reduced product size and costs. This
combination also may allow our customers to decrease time-to-market and reduce
the number of their suppliers.

     In addition to our internal research and development team, we also work
closely with universities around the world. We also have entered into joint
research and development initiatives with a number of our customers.

     Our research and development expenditures were $951 million, $827 million
and $683 million for fiscal years 2001, 2000 and 1999, respectively. We
anticipate that we will continue to make significant research and development
expenditures to maintain our competitive position with a continuing flow of
innovative products, technology and manufacturing processes, although at lower
levels than in fiscal 2001. We expect to fund our future research and
development expenditures from our operations.

STRATEGIC RELATIONSHIPS

     As part of our manufacturing strategy, we have entered into joint ventures
with various partners. We also have developed strategic relationships to augment
our technological capabilities.

  MANUFACTURING RELATIONSHIP

     In December 1997, we entered into a joint venture, called Silicon
Manufacturing Partners, with Chartered Semiconductor Manufacturing Ltd., a
leading manufacturing foundry for integrated circuits, to operate a 54,000
square foot integrated circuit manufacturing facility in Singapore. We have a
51% equity interest in this joint venture, and Chartered Semiconductor owns the
remaining 49% equity interest. Under the terms of our agreement with Chartered
Semiconductor and Silicon Manufacturing Partners, we agreed to purchase 51% of
the production output from this facility and Chartered Semiconductor agreed to
purchase the
                                        15
<PAGE>

remaining 49% of the production output. If we do not purchase all the wafers
allotted to us, we are obligated to reimburse the joint venture for the portion
of fixed costs associated with the unpurchased wafers. Chartered Semiconductor
is similarly obligated with respect to the wafers allotted to it. Chartered
Semiconductor will also have the right of first refusal to the wafers produced
in excess of our requirements. The joint manufacturing venture is currently
operational.

     The agreement may be terminated by either party upon two years written
notice, but may not be terminated prior to February 2008. The agreement also may
be terminated for material breach, bankruptcy or insolvency.

  TECHNOLOGY RELATIONSHIPS

     Our most important technology relationships are described below.

  Integrated Circuit Manufacturing Process Technology

     In July 2000, we entered into an agreement with Chartered Semiconductor
committing us and Chartered Semiconductor to jointly develop manufacturing
technologies for future generations of integrated circuits targeted at
communications markets. We have agreed to invest up to $350 million over a five
year period. As part of the joint development activities, our two companies will
staff a new research and development team at Chartered Semiconductor's Woodlands
campus in Singapore. These scientists and engineers will work with our teams in
Murray Hill, New Jersey, and Orlando, Florida, as well as with Chartered
Semiconductor's technology development organization.

     During the term of the agreement and for five years thereafter, we and
Chartered Semiconductor will be required to update each other, without
compensation, with technical information relating to any corrections or
improvements made to the processes which we have jointly developed. All
intellectual property jointly developed, other than patents, will be jointly
owned by us and Chartered Semiconductor. Jointly made inventions and patents
which issue from these inventions will be equally divided between us and
Chartered Semiconductor, and the non-owning party will receive a nonexclusive,
royalty-free and nontransferable license for each invention or patent. The
agreement may be terminated for breach of material terms upon 30 days notice or
for convenience upon six months notice prior to the planned successful
completion of a development project, in which case the agreement will terminate
upon the actual successful completion of such project.

  StarCore

     In June 1998, we entered into a Joint Design Center operating agreement
with Motorola, Inc. to develop advanced digital signal processor technologies.
We and Motorola develop these technologies in a joint design center called the
StarCore Technology Center located in Atlanta, Georgia. We and Motorola equally
share the funding of the costs and expenses of operating the center. The board
of advisors comprised of ours and Motorola's representatives will determine, on
a yearly basis, the annual budget for operating the center. The StarCore
Technology Center designs digital signal processor cores and development tools
that we can incorporate in our complete system-on-a-chip solutions for
communications applications. StarCore focuses on digital signal processor
technologies for cellular base stations and the transmission of wireless data
and other applications. The StarCore SC-140 digital signal processor core, the
first core developed by the StarCore Technology Center, was produced in April
1999. We are currently sampling integrated circuit solutions which include this
digital signal processor core.

     During the term of the agreement, the items developed within the joint
design center, other than patents, may be licensed to third parties only upon
mutual consent by Motorola and us. All joint patents, which are patents arising
out of inventions made jointly by our employees or consultants and those of
Motorola where such employees or consultants were assigned to the joint design
center, will be jointly owned by us and Motorola. We and Motorola will be free
to use these jointly owned patents for any purpose and to license third parties
under these patents without approval from the other.

                                        16
<PAGE>

     The initial term of the agreement will expire on May 1, 2008, and may be
extended for successive two year periods by mutual agreement. We and Motorola
will review the operations of the joint design center in June 2002 and every two
years thereafter. After any such review either we or Motorola may terminate the
agreement upon one year written notice. The agreement also may be terminated for
breach of material terms, insolvency or bankruptcy.

  MEMS

     We have entered into a joint design center agreement with Lucent to develop
technology for micro electro-mechanical systems, or MEMS, which are small
mechanical devices that perform a variety of functions. The primary focus of the
joint design center will be the development of optical MEMS. We and Lucent have
both agreed to jointly fund, manage and staff the joint design center over the
following three years to develop this technology. We and Lucent each have a
one-half interest in the MEMS technical information owned by Lucent as of
February 1, 2001. We and Lucent have granted each other a perpetual,
nonexclusive, royalty-free license in our respective patents which issue from
applications having an effective first filing date prior to February 1, 2003 to
make and sell MEMS products. All joint patents, which are patents issued from
any application filed with respect to any invention made jointly by us and
Lucent while working on a joint design center product and conceived or reduced
to practice during performance under the agreement, will be jointly owned by us
and Lucent. We and Lucent will be free to use these jointly owned patents for
any purpose and to license third parties under these patents. Some of these
products may be manufactured exclusively for Lucent, subject to some
restrictions, for a limited period following the first commercial availability
of a product, on a case by case basis. The initial term of the agreement will
expire on January 31, 2004. The agreement may be terminated for breach of
material terms or by prior written notice of either party for convenience.

PATENTS, TRADEMARKS AND OTHER INTELLECTUAL PROPERTY

     We own or have rights to a number of patents, trademarks, copyrights, trade
secrets and other intellectual property directly related to and important to our
business. Under the intellectual property agreements we entered into with Lucent
as part of the separation, Lucent has assigned or exclusively licensed to us
approximately 6,000 U.S. patents and patent applications and their corresponding
foreign patents and patent applications. These patents include patents related
to the following technologies:

     - integrated circuit and optoelectronic manufacturing processes;

     - lasers;

     - optical modulators;

     - lithium niobate devices;

     - optoelectronic receivers; and

     - integrated circuits for use in products such as modems, digital signal
       processors, wireless communications, network processors and communication
       protocols.

     In connection with these patents, we have entered into a cross license
agreement with Lucent. In addition, we have received a joint ownership interest
in patents and patent applications relating to optical micro electro-mechanical
systems, or MEMS.

     Lucent has also granted us rights and licenses to patents, trademarks,
copyrights, trade secrets and other intellectual property that are not directly
related to our business but help facilitate our business. We also have received
non-exclusive licenses to all other patents retained by Lucent, including
patents in areas such as optical fiber, audio and video coding and
telecommunications systems. In addition, Lucent has conveyed to us numerous
sublicenses under patents of third parties. We derive revenue from licensing our
intellectual property.

                                        17
<PAGE>

     In addition, Lucent has assigned to us numerous trademarks, both in the
United States and in foreign countries. The primary trademarks used in the sale
of our products have been transferred to us, except for the Lucent name and logo
and the Bell Laboratories name.

     The patents described above include patents of all ages ranging from
pending applications, which will have a duration of 20 years from their filing
dates, through patents soon to expire. The agreements do not provide for
termination.

     We indemnify our customers for some of the costs and damages of patent
infringement in circumstances where our product is the primary factor creating
the customer's infringement exposure. We generally exclude coverage where
infringement arises out of the combination of our products with products of
others.

     We expect to protect our products and processes by asserting our
intellectual property rights where appropriate and prudent. We also will obtain
patents, copyrights, and other intellectual property rights used in connection
with our business when practicable and appropriate.

GOVERNMENT REGULATION

     Many of our customers' end products that include our integrated circuits or
optoelectronic components are subject to extensive telecommunications-based
regulation by the United States and foreign laws and international treaties. We
must design and manufacture our products to ensure that our customers are able
to satisfy a variety of regulatory requirements and protocols established to,
among other things, avoid interference among users of radio frequencies and to
permit interconnection of equipment. For example, disk drives that include our
integrated circuits need to satisfy Federal Communications Commission emissions
testing. Cellular base stations that include our integrated solutions must be
qualified by the Federal Communications Commission that they meet radio
frequency spectrum requirements. In addition, some of our equipment products,
such as our wireless local area networking products, must be certified to
safety, electrical noise and communications standards compliance.

     Each country has different regulations and a different regulatory process.
In order for our customers' products to be used in some jurisdictions,
regulatory approval and, in some cases, specific country compliance testing and
re-testing may be required. The delays inherent in this regulatory approval
process may force our customers to reschedule, postpone or cancel the
incorporation of our products into their products, which may result in
significant reductions in our sales. The failure to comply with current or
future regulations or changes in the interpretation of existing regulations in a
particular country could result in the suspension or cessation of sales in that
country by us or our customers. It also may require us to incur substantial
costs to modify our products to aid our customers in complying with the
regulations of that country.

     We work with consultants, counsel and testing laboratories to support our
compliance efforts as necessary. These individuals work to ensure that our
products comply with the requirements of the Federal Communications Commission
in the United States and with the requirements of the European
Telecommunications Standards Institute in western Europe, as well as with the
various individual regulations of other countries.

     The regulatory environment in which we operate is subject to changes due to
political, economic and technical factors. In particular, as use of wireless
technology expands and as national governments continue to develop regulations
for this technology, we may need to comply with new regulatory standards
applicable to our products. Changes in our regulatory environment that generally
result from our expansion into new areas or changes in current regulations could
increase the cost of manufacturing our products because we must continually
modify our products to respond to these changes.

     In addition, domestic and international authorities continue to regulate
the allocation and auction of the radio frequency spectrum. These regulations
have a direct impact on us because many of our customers' licensed products can
be marketed only if permitted by suitable frequency allocations, auctions and
regulations. The implementation of these regulations may delay our end-users in
deploying their systems, which could, in turn, lead to delays in orders of our
products by our customers and end users. Further, when we license hardware and
software designs for mobile telephones that use our integrated circuits, we work
with

                                        18
<PAGE>

our customers to help them achieve full certification approval for their mobile
telephones, which is a prerequisite for them to be able to sell their mobile
telephones.

EMPLOYEES

     As of September 30, 2001, we employed approximately 14,400 full-time
employees, including approximately 2,700 research and development employees and
7,600 manufacturing employees. During fiscal 2001, we announced a series of
restructuring initiatives that include closing our Madrid manufacturing location
by the end of the calendar year and reducing employment worldwide by
approximately 6,000 positions, of which 4,300 had been eliminated by September
30, 2001. Of our 14,400 employees at September 30, 2001, approximately 7,650
were management and non union-represented employees, and approximately 3,450
were U.S. union-represented employees covered by collective bargaining
agreements. In addition, approximately 200 employees were union-represented
employees located in Mexico and covered by a collective bargaining agreement.

     On May 31, 1998, Lucent entered into a collective bargaining agreement with
the Communications Workers of America and into a separate agreement with the
International Brotherhood of Electrical Workers. In connection with our
separation from Lucent, we will assume the obligations under these agreements
with respect to our U.S. union-represented employees. These agreements will be
effective until May 31, 2003, unless the parties to each agreement reach a
mutual agreement to amend the terms. All of our unionized employees in Mexico
are members of the Mexican National Union of Industrial Workers. We entered into
a collective bargaining agreement with this union on January 10, 2000. As is
typical in Mexico, wages are renegotiated every year, while other terms and
conditions of employment are renegotiated every two years. We believe that we
generally have a good relationship with our employees and the unions that
represent them. We are subject from time to time to unfair labor charges filed
by the unions with the National Labor Relations Board. If we are unsuccessful in
resolving these charges, our operations may be disrupted or we may incur
additional costs that may adversely affect our results of operations. If we
experience any work stoppages by our union employees, we believe that we may be
affected to a greater extent than our competitors.

BACKLOG

     Our backlog, which represents the aggregate of the sales price of orders
received from customers, but not yet recognized as revenue, was approximately
$769 million and $1.9 billion on September 30, 2001 and September 30, 2000,
respectively. The majority of these orders are fulfilled within three months.
All orders, however, are subject to possible rescheduling by customers. Our
customers often change their order two or three times between initial order and
delivery. Our customers' frequent changes usually relate to quantities or
delivery dates, but sometimes relate to the specifications of the products we
are shipping. Although we believe that the orders included in the backlog are
firm, orders may generally be cancelled by the customer without penalty. We also
may elect to permit cancellation of orders without penalty where management
believes it is in our best interests to do so. For these reasons, we believe
that our backlog at any given date is not a meaningful indicator of future
revenues.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

     We are subject to a wide range of laws and regulations relating to
protection of the environment and employee health and safety. Most of our
manufacturing facilities have undergone regular internal audits relating to
environmental, health and safety requirements. Most of those facilities also are
regularly audited and certified by an independent and accredited third party
registrar, such as Lloyd's Register Quality Assurance, as conforming to the
internationally recognized ISO 14001 standard relating to environmental
management. In addition, most of our non-U.S. manufacturing facilities conform
to BS 8800, the British standard for occupational health and safety management
systems. Based upon these reviews, we believe that our manufacturing facilities
are in substantial compliance with all applicable environmental, health and
safety requirements.

                                        19
<PAGE>

     We are subject to environmental laws, including the Comprehensive
Environmental Response, Compensation and Liability Act, also known as Superfund,
that require the cleanup of soil and groundwater contamination at sites
currently or formerly owned or operated by us, or at sites where we may have
sent waste for disposal. These laws often require parties to fund remedial
action at sites regardless of fault. Lucent is a potentially responsible party
at numerous Superfund sites and sites otherwise requiring cleanup action. With
some limited exceptions, under the agreement governing our separation from
Lucent, we have assumed all environmental liabilities resulting from our
businesses, which include liabilities for the costs associated with eight of
these sites -- five Superfund sites, two of our former facilities and one of our
current manufacturing facilities.

ORGANIZATIONAL STRUCTURE EFFECTIVE OCTOBER 1, 2001

     Effective October 1, 2001, we aligned our products under two new
market-focused groups, Infrastructure Systems and Client Systems, that target
the network equipment and consumer communications markets respectively.

     In addition, we have combined the supply chain management and manufacturing
activities of both integrated circuits devices and optoelectronics components
under a new Operations support organization to bring a full-systems perspective
to our manufacturing processes. This group manages manufacturing and the full
supply chain across both the systems groups.

  INFRASTRUCTURE SYSTEMS GROUP

     We are consolidating research and development, as well as marketing, for
both integrated circuits devices and optoelectronics aimed at communications
systems under the Infrastructure group. This will allow us to design, develop
and deliver complete, interoperable solutions to equipment manufacturers for
advanced enterprise, access, metropolitan, long-haul and undersea applications.

  CLIENT SYSTEMS GROUP

     The Client Systems group will focus primarily on wireless data and computer
communications applications. The group will deliver semiconductor solutions for
a variety of end-user applications such as modems, Internet-enabled cellular
terminals and hard-disk drives for computers. In addition, the group will offer
semiconductor, software, systems and wireless local area network (LAN) solutions
through the ORiNOCO product family.

ITEM 2.  PROPERTIES

     As of September 30, 2001, we operated 13 manufacturing facilities and four
warehouse locations in the United States and five other countries. We also
operated an additional 65 facilities, including research and development
facilities and design centers. We operate facilities in a total of 19 countries.
Our principal owned manufacturing facilities were located in the United States,
Mexico, Singapore, Spain and Thailand, although we are in the process of closing
our facility in Spain. We also have a 51% interest in our Silicon Manufacturing
Partners joint venture located in Singapore which is predominantly used as a
manufacturing site. Our facilities had an aggregate floor space of approximately
8.3 million square feet, of which approximately 5.5 million square feet is owned
and approximately 2.8 million square feet is leased. Our lease terms range from
monthly leases to 14 years. We believe that all of our facilities and equipment
are in good condition and are well maintained and able to operate at present
levels.

ITEM 3.  LEGAL PROCEEDINGS

     The information required by this Item is included in Item 7 of Part II of
this Form 10-K under the heading "Legal Proceedings."

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

PRICE RANGE OF COMMON STOCK

     Agere's Class A common stock trades on the New York Stock Exchange under
the symbol "AGR.A." The high and low sale prices for our Class A common stock
for each quarter since our initial public offering on March 27, 2001 are set
forth below:

<Table>

June 30, 2001...............................................   9.50    4.10
September 30, 2001..........................................   7.50    3.10
</Table>

     As of December 1, 2001 there were approximately 739 holders of record of
the Class A common stock. However, we believe that the number of beneficial
owners is substantially greater than the number of record holders, because a
large portion of the Class A common stock is held of record through brokerage
firms in "street name."

     All of Agere's outstanding Class B common stock is held by Lucent. There is
currently no established trading market for our Class B common stock.

DIVIDEND POLICY

     We do not anticipate paying any dividends on our common stock in the
foreseeable future. We currently intend to retain our future earnings for use in
the operation and expansion of our business. Under our bank credit facility, we
are not permitted to pay any dividends on our common stock other than dividends
payable solely in additional shares of our common stock and dividends pursuant
to our stockholders' rights plan.

(1) During fiscal 2001 we received approximately $3.4 billion of net proceeds
    from our initial public offering and recorded a $2.8 billion impairment of
    goodwill and other acquired intangibles related to our acquisitions of Ortel
    Corporation, Herrmann Technology, Inc., Agere, Inc. and Enable
    Semiconductor, Inc. We also assumed $2.5 billion of debt from Lucent
    Technologies Inc., consisting of short-term borrowings under a credit
    facility provided by financial institutions. We did not receive any of the
    proceeds of this short-term debt.

(2) During fiscal 2000 goodwill and other acquired intangibles increased by $3.4
    billion due to the acquisitions of Ortel, Herrmann, Agere, Inc. and
    substantially all the assets of VTC Inc., whose results of operations are
    included from their respective dates of acquisition.

(3) Effective October 1, 2000, we adopted Statement of Financial Accounting
    Standards No. 133, "Accounting for Derivative Instruments and Hedging
    Activities," as amended.

     Effective October 1, 1998, we changed our method for calculating the
     market-related value of plan assets used in determining the expected
     return-on-asset component of annual net pension and postretirement benefit
     costs.

(4) Basic and diluted earnings (loss) per common share are calculated by
    dividing income (loss) by the weighted average number of common shares
    outstanding during the period. The weighted average number of common shares
    outstanding on a historical basis includes the retroactive recognition to
    October 1, 1996 of the 1,035,000,000 shares owned by Lucent prior to our
    initial public offering.

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

     The following discussion of our financial condition and results of
operations should be read in conjunction with our consolidated and combined
financial statements and the notes thereto. This discussion contains
forward-looking statements. Please see "Forward-Looking Statements" and "Factors
Affecting Our Future Performance" for a discussion of the uncertainties, risks
and assumptions associated with these statements.

OVERVIEW

     We are the world leader in sales of communication components, which include
integrated circuits and optical components. Communication components are the
basic building blocks of electronic and photonic products and systems for
terrestrial and submarine, or undersea, communications networks and for
communications equipment. We sell our integrated circuits and optoelectronic
components globally to manufacturers of communications and computer equipment.

     We report our operations in two segments: Integrated Circuits and
Optoelectronics. Integrated circuits, or chips, are made using semiconductor
wafers imprinted with a network of electronic components. They are designed to
perform various functions such as processing electronic signals, controlling
electronic system functions and processing and storing data. The Integrated
Circuits segment includes our wireless local area networking products, which
facilitate the transmission of data and voice signals within a localized area
without cables or wires. The Optoelectronics segment represents our
optoelectronic components operations, including both our active optoelectronic
and our passive optical components. Optoelectronic components transmit, process,
change, amplify and receive light that carries data and voice traffic over
optical networks. The Integrated Circuits and Optoelectronics segments each
include revenue from the licensing of intellectual property related to that
segment.

  SEPARATION FROM LUCENT

     We were incorporated under the laws of the State of Delaware on August 1,
2000, as a wholly owned subsidiary of Lucent. We had no material assets or
activities as a separate corporate entity until the contribution to us by Lucent
of its integrated circuits and optoelectronic components businesses. Lucent
conducted these businesses through various divisions and subsidiaries. On
February 1, 2001, Lucent began the separation of our company by transferring to
us the assets and liabilities related to these businesses. The separation was
substantially completed, including the transfer of all assets and liabilities
other than prepaid pension costs and postretirement liabilities, which have yet
to be transferred, when we completed our initial public offering in April 2001.
As of September 30, 2001, Lucent owned 100% of our outstanding Class B common
stock and 37 million shares of our outstanding Class A common stock, which
represented approximately 58% of the total outstanding common stock and
approximately 84% of the combined voting power of both classes of our common
stock with respect to the election and removal of directors.

     Lucent originally announced its intention to distribute all shares of our
common stock it then owned to its shareholders in a tax-free distribution by
September 30, 2001. On August 16, 2001, Lucent amended its credit facilities.
The amended credit facilities modified the conditions that must be met before
Lucent can distribute its Agere stock to its stockholders. The distribution of
Agere stock can occur at Lucent's request if the following terms and conditions,
as defined under Lucent's credit facilities, are met by Lucent:

     - no event of default exists under the credit facilities;

     - generated positive earnings before interest, taxes, depreciation and
       amortization for the fiscal quarter immediately preceding the
       distribution;

     - meet a minimum current asset ratio;
                                        23
<PAGE>

     - receipt of $5,000 million in cash from certain non-operating sources; and

     - its 364-day $2,000 million credit facility has been terminated and its
       $2,000 million credit facility expiring in February 2003 has been reduced
       to $1,750 million or less.

     On November 30, 2001, Lucent stated it remained committed to completing the
process of separating Agere from Lucent, and that it intended to move forward
with the distribution of the Agere stock it held in a tax-free spin off to its
shareholders. Because Lucent must meet a number of conditions before it can
complete the spin off and because Lucent alone will make the decision about
whether to complete the spin off, even if the conditions were met, we can not
assure you that Lucent will complete the spin off by a particular date or at
all.

     In connection with our separation from Lucent, we entered into several
agreements with Lucent regarding, among other things, interim services,
intellectual property and product supply. The interim services agreement sets
forth charges generally intended to allow the providing company to fully recover
the allocated direct costs of providing the services, plus all out-of-pocket
costs and expenses. For more information, see note 19 to our financial
statements in Item 8.

     Lucent is our largest customer with purchases in fiscal 2001, 2000 and 1999
representing 14.9%, 21.3% and 25.7%, respectively, of our revenue. We expect
Lucent will continue to represent a significant percentage of our revenue in the
foreseeable future.

     Our financial statements include amounts prior to February 1, 2001 that
have been derived from the financial statements and accounting records of Lucent
using the historical results of operations and historical basis of the assets
and liabilities of our businesses. We believe the assumptions underlying our
financial statements are reasonable. However, our financial statements for
periods prior to February 1, 2001 may not necessarily reflect our results of
operations, financial position and cash flows in the future or what our results
of operations, financial position and cash flows would have been had we been a
stand-alone company during the periods presented. Because a direct ownership
relationship did not exist among all the various units comprising Agere,
Lucent's net investment in us is shown in lieu of stockholders' equity in our
financial statements for periods prior to February 1, 2001. For periods prior to
February 1, 2001, our financial statements include allocations of Lucent's
expenses, assets and liabilities, including allocations for general corporate
expenses, basic research, interest expense, pension and postretirement costs,
income taxes and cash and receivables, which are discussed in note 1 to our
financial statements in Item 8.

  ACQUISITIONS

     During fiscal 1999 and 2000 we completed the acquisitions described below
as part of our efforts to broaden our portfolio of product offerings. We did not
have any significant acquisitions during fiscal 2001.

     In June 2000, we acquired Herrmann, a developer and manufacturer of passive
optical filters that can be used in conjunction with active optoelectronic
components in products such as amplifiers. The purchase price was $432 million
in Lucent common stock and options. In connection with this acquisition, certain
former stockholders of Herrmann are entitled to receive up to a total of 677,019
additional shares of Lucent common stock based on retention and the achievement
of specified milestones, which require the production of two products at
improved manufacturing yields within the three-year period following the
acquisition. As of September 30, 2001, 200,000 shares of Lucent common stock had
been released based on the achievement of milestones, resulting in additional
goodwill related to the acquisition. The achievement of additional milestones
may also result in additional goodwill.

     In April 2000, we acquired Ortel, a developer and manufacturer of
semiconductor optoelectronic components used in fiber optic systems for cable
television and data communications networks. The purchase price was $2,998
million in Lucent common stock and options.

     In April 2000, we acquired Agere, Inc., a developer and supplier of network
processor integrated circuits. Network processors control how data is sent over
a network. The purchase price was $377 million in Lucent common stock and
options.

                                        24
<PAGE>

     In March 2000, we acquired substantially all the assets of VTC, a supplier
of integrated circuits to computer hard disk drive manufacturers. The purchase
price was $104 million in cash. In connection with this acquisition,
stockholders of VTC are entitled to receive additional cash consideration of up
to $50 million contingent on the delivery of product at specified manufacturing
yields and the transfer and qualification of process technology to our
manufacturing facilities. As of September 30, 2001, $30 million of the
additional cash consideration had been paid, resulting in additional goodwill
related to the acquisition. Any future contingent cash consideration paid will
also be recorded as additional goodwill.

     In March 1999, we acquired Enable, a developer of integrated circuits for
local area network equipment. The purchase price was $51 million in cash.

     In February 1999, we acquired Sybarus Technologies ULC, a developer of
integrated circuits for communications networks. The purchase price was $41
million in cash.

     During fiscal 2001, we performed impairment evaluations of the goodwill and
other acquired intangibles from recent acquisitions. The assessments were
performed in accordance with Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of," as a result of weakening economic conditions and
decreased current and expected future demand for products in the markets in
which we operate. We determined the fair value of the acquired entities using a
discounted cash flow model based on growth rates and margins reflective of the
current decrease in demand for our products, as well as anticipated future
demand. Discount rates used were based upon our weighted average cost of capital
adjusted for business risks. These assumptions were based on management's best
estimate of future results. As a result of the assessments, we determined that
an other than temporary impairment of goodwill and other acquired intangibles
existed. We recorded a charge to reduce goodwill and other acquired intangibles
of $2,762 million during fiscal 2001, consisting of $2,220 million, $275
million, $240 million and $27 million related to Ortel, Herrmann, Agere, Inc.
and Enable, respectively.

  OPERATING TRENDS

     Order levels and revenues declined significantly in the latter half of
fiscal 2001 and are expected to remain at lower levels in the near-term. We
believe the decreases are due to weakness in our customers' markets and excess
inventory held by our customers. We experienced a higher than normal level of
order cancellations and reschedules during the second half of fiscal 2001.
Although the level of customer order changes has decreased in recent months, our
order backlog is lower than we have experienced in the past. Because of this
reduced backlog and the potential for additional order changes by customers our
ability to forecast future results is limited.

     Our costs consist primarily of manufacturing overhead, materials and labor.
Similar to many semiconductor manufacturers, we have relatively high fixed costs
associated with our wafer manufacturing. As a result, our ability to reduce
costs quickly in times of decreased demand is limited, which has an adverse
effect on margins. Because we anticipated higher revenues as we entered fiscal
2001, our cost structure reflected manufacturing capacity and resources greater
than those actually required. In light of the lower revenues we have experienced
in recent quarters, we have taken a number of steps to reduce our cost
structure, including restructuring activities and reductions in capital
spending. We continue to evaluate our cost and expense structure and expect to
announce additional actions during fiscal year 2002 to further reduce our costs,
expenses and break-even point.

  RESTRUCTURING AND SEPARATION EXPENSES AND INVENTORY PROVISION

     In fiscal 2001, we announced a series of restructuring initiatives to
reduce our cost structure in light of declining revenues. We recorded a
restructuring charge of $563 million in fiscal 2001 classified within
restructuring and separation expenses. These restructuring initiatives include a
worldwide workforce reduction, rationalization of manufacturing capacity and
other activities.

     The restructuring initiatives announced in fiscal 2001 will result in a
workforce reduction of approximately 6,000 employees across various business
functions, operating units and geographic regions, and

                                        25
<PAGE>

includes both management and occupational employees. We recorded a restructuring
charge of $177 million in fiscal 2001 related to approximately 5,500 employees,
of which approximately 4,300 employees had been taken off-roll as of September
30, 2001, and expect to record a restructuring charge of approximately $20
million related to the additional 500 employees by the end of the first quarter
of fiscal 2002. Of the $177 million charge, $28 million represents termination
benefits to U.S. management employees that will be funded through Lucent's
pension assets. Severance costs and other exit costs noted above were determined
in accordance with Emerging Issues Task Force No. 94-3, "Liability Recognition
for Certain Employee Termination Benefits and Other Costs to Exit an Activity."
In addition, on December 5, 2001, we announced our intention to further reduce
our workforce by approximately 950 positions. See note 22 to our financial
statements in Item 8 for further information about this reduction.

     We recorded a restructuring charge of $386 million in fiscal 2001 relating
to the rationalization of under-utilized manufacturing facilities and other
restructuring-related activities. We have discontinued manufacturing operations
at our chip fabrication plant in Madrid, Spain and have agreed to sell the
facility. We are also rationalizing under-utilized manufacturing capacity at our
facilities in Orlando, Florida, and in Allentown, Breiningsville and Reading,
Pennsylvania. In addition, we are consolidating several satellite-manufacturing
sites, as well as leased corporate offices. The restructuring charge for fiscal
2001 includes $37 million related to facility closings primarily for lease
terminations, non-cancelable leases and related costs. It also includes an asset
impairment charge of $287 million related to property, plant and equipment
associated with the consolidation of manufacturing and other corporate
facilities. This charge was recognized in accordance with the guidance on
impairment of assets in Statement 121. The remaining restructuring charge of $62
million relates primarily to contract terminations.

     A summary of restructuring charges is outlined as follows:

</Table>

     We anticipate that the majority of the remaining cash expenditures relating
to workforce reductions will be paid by the end of the first quarter of fiscal
2002 and the majority of the contract termination payments will be paid by the
end of the second quarter of fiscal 2002. Amounts related to non-cancelable
lease obligations due to the consolidation of facilities will be paid over the
respective lease terms through fiscal 2005. We expect to substantially complete
implementation of the announced restructuring program by December 31, 2001. We
currently estimate future annualized pre-tax savings to be approximately $550
million, of which $440 million are cash savings. The full benefit of these
savings will begin to be recognized in the second quarter of fiscal 2002.

     We incurred costs, fees and expenses relating to our separation from
Lucent. These costs, fees and expenses were primarily related to legal
separation matters; the establishment of a separate computer and information
technology infrastructure and associated information processing and network
support; marketing relating to building a company brand identity; and,
implementing treasury, real estate, pension and records retention management
services. For fiscal 2001 we incurred $99 million of separation expenses
classified within restructuring and separation expenses. Additional separation
costs that we may incur in future periods are contingent on the form and timing
in which we achieve our full independence from Lucent.

     We recorded inventory provisions, classified within cost of sales, of $409
million in fiscal 2001 compared to inventory provisions of $29 million in fiscal
2000. The fiscal 2001 amount, which includes purchase order cancellation
charges, reflects a significant decrease in forecasted revenue and was
calculated in accordance

                                        26
<PAGE>

with our inventory valuation policy, which is based on a review of forecasted
demand compared with existing inventory levels.

  REORGANIZATION

     Effective October 1, 2001, we have aligned our products under two new
market-focused groups, Infrastructure Systems and Client Systems, that target
the network equipment and consumer communications markets respectively. The
Infrastructure Systems group includes our optoelectronics components business
and portions of our integrated circuits business and will facilitate the
convergence of products from both businesses as we address markets in high-speed
communications systems. The Client Systems group includes our wireless data,
computer communications, storage and wireless terminal solutions products that
address end-user applications markets.

</Table>

     Revenue.  Revenue decreased 13% or $628 million, to $4,080 million in
fiscal 2001 from $4,708 million in fiscal 2000, primarily due to volume
decreases in the Integrated Circuits segment. The decrease of $638 million
within the Integrated Circuits segment was driven by volume decreases across the
segment, which were partially offset by increased revenues from our wireless
local area networking product offerings. The increase of $10 million within the
Optoelectronics segment was due to increased sales of components used in
submarine network, transponder and access applications, offset by a decrease in
sales of components used in high-speed long haul applications.

     During fiscal 2001 revenues decreased sequentially each quarter due to
declining market conditions compared to sequential revenue growth each quarter
in fiscal 2000. Integrated Circuits revenues declined $627 million or 57% to
$469 million in the fourth quarter of fiscal 2001 from the peak quarterly
revenue level of $1,096 million experienced in the fourth quarter of fiscal
2000. Optoelectronic revenues declined $293 million or 69% to $131 million in
the fourth quarter of fiscal 2001 from the peak quarterly revenue level of $424
million experienced in the first quarter of fiscal 2001.

     Costs and gross margin.  Costs increased 21% or $529 million, to $3,084
million in the current fiscal year from $2,555 million in the prior fiscal year.
Gross margin decreased 21.3 percentage points to 24.4% in fiscal 2001 from 45.7%
in fiscal 2000, primarily due to lower manufacturing capacity utilization and
increased inventory provisions. Gross margin for the Integrated Circuits segment
declined to 30.0% in fiscal 2001 from 44.7% in fiscal 2000 primarily due to
lower manufacturing capacity utilization and increased inventory provisions.
Gross margin for the Optoelectronics segment decreased to 11.1% in fiscal 2001
from 48.7% in fiscal 2000 due to increased inventory provisions, lower
manufacturing capacity utilization and a change in product mix, particularly
from higher margin components of high-speed long haul applications to lower
margin components.

     Selling, general and administrative.  Selling, general and administrative
expenses increased 12% or $62 million, to $597 million in fiscal 2001 from $535
million in fiscal 2000. This was primarily due to increases

                                        27
<PAGE>

in general and administrative expenses associated with being a stand-alone
company, which were partially offset by lower bonus accruals.

     Research and development.  Research and development expenses increased 15%
or $124 million, to $951 million in fiscal 2001 from $827 million in fiscal
2000. The increase was due to new and ongoing product development expenses,
including a full year of expenses associated with acquisitions during fiscal
2000, partially offset by lower bonus accruals.

     Purchased in-process research and development.  Purchased in-process
research and development decreased to zero in fiscal 2001 from $446 million in
fiscal 2000. This is the result of no significant acquisitions being made in
fiscal 2001, while a number of acquisitions were completed in fiscal 2000.

     Amortization of goodwill and other acquired intangibles.  Amortization
expense increased $226 million to $415 million in fiscal 2001 from $189 million
in fiscal 2000 due to the recognition in fiscal 2001 of amortization associated
with acquisitions completed during fiscal 2000.

     Restructuring and separation expenses.  Restructuring and separation
expenses of $662 million were incurred in fiscal 2001. We recorded $563 million
of restructuring charges. We also incurred expenses of $99 million in connection
with our separation from Lucent.

     Impairment of goodwill and other acquired intangibles.  During fiscal 2001,
we determined that an other than temporary impairment of goodwill and other
acquired intangibles existed and recorded a charge of $2,762 million to reduce
goodwill and other acquired intangibles.

     Operating income (loss).  Operating loss was $4,391 million in fiscal 2001
compared to $156 million of operating income in fiscal 2000. This was driven
primarily by the impairment of goodwill and other acquired intangibles, a
decline in gross profit, restructuring and separation expenses and an increase
in the amortization of goodwill and other acquired intangibles, partially offset
by the absence of purchased in-process research and development costs in fiscal
2001. Although performance measurement and resource allocation for the
reportable segments are based on many factors, the primary financial measure
used is operating income (loss) by segment, exclusive of purchased in-process
research and development costs, amortization of goodwill and other acquired
intangibles, restructuring and separation expenses, and impairment of goodwill
and other acquired intangibles. The following table shows the change in
operating income by segment:

     Other income-net.  Other income-net increased 6% or $2 million, to income
of $35 million in fiscal 2001 from income of $33 million in fiscal 2000. The $35
million in fiscal 2001 was comprised of interest income from our investment of
the proceeds from our initial public offering, income from our equity investment
in Silicon Manufacturing Partners Pte Ltd., the impairment of several
non-consolidated investments and foreign exchange losses. The $33 million in
fiscal 2000 was comprised primarily of gains on sale of investments and foreign
exchange gains.

     Interest Expense.  Interest expense increased $93 million to $151 million
in fiscal 2001 from $58 million in fiscal 2000. This increase is due to interest
on the $2,500 million of short-term debt we assumed from Lucent in April 2001.

     Provision for income taxes.  The effective tax rates were (2.3%) and 158.0%
for fiscal 2001 and 2000, respectively. The fiscal 2001 effective tax rate
includes the impact of recording a valuation allowance of approximately $553
million for deferred tax assets, and the effects of non-tax deductible goodwill
amortization

                                        28

and separation costs. The fiscal 2000 effective tax rate includes the impact of
non-tax deductible goodwill amortization and non-tax deductible purchased
in-process research and development.

</Table>

     Revenue.  Revenue increased 27%, or $994 million, to $4,708 million in
fiscal 2000 from $3,714 million in fiscal 1999, primarily due to volume
increases in both the Integrated Circuits and Optoelectronics segments. The
increase of $452 million in the Integrated Circuits segment was driven by
increases across our integrated circuits product offerings except for a decrease
in fiscal 2000 sales of our integrated circuits for wireless terminal devices
due to a missed design win with a large customer in 1999, which resulted in our
not generating sales from a generation of that customer's mobile telephones. The
increase of $542 million in the Optoelectronics segment was driven by increased
sales primarily to existing customers of many of our key optoelectronic
components for high-speed transport and submarine network applications.

     Costs and gross margin.  Costs increased 31%, or $606 million, to $2,555
million in fiscal 2000 from $1,949 million in fiscal 1999, primarily due to
increased sales volume. Gross margin decreased 1.8 percentage points to 45.7% in
fiscal 2000 from 47.5% in fiscal 1999. Gross margin for the Integrated Circuits
segment was 44.7% in fiscal 2000 and 48.6% in fiscal 1999. The decrease in
Integrated Circuits gross margin was primarily due to lower average revenues per
unit. Gross margin for the Optoelectronics segment increased to 48.7% in fiscal
2000 from 42.5% in fiscal 1999. The increase in Optoelectronics gross margin was
due primarily to the volume growth in the business, which resulted in a more
efficient utilization of manufacturing capacity.

     Selling, general and administrative.  Selling, general and administrative
expenses decreased 7%, or $38 million, to $535 million in fiscal 2000 from $573
million in fiscal 1999. This decrease was primarily due to lower costs
associated with the implementation of our advanced logistics and planning
systems. These systems were primarily implemented and paid for in fiscal 1999.

     Research and development.  Research and development expenses increased 21%,
or $144 million, to $827 million in fiscal 2000 from $683 million in fiscal
1999. This increase was primarily due to new and ongoing product development
expenses within the Integrated Circuits and Optoelectronics segments, including
$50 million added during the year as a result of our acquisitions.

     Purchased in-process research and development.  Purchased in-process
research and development increased $429 million, to $446 million in fiscal 2000
from $17 million in fiscal 1999. This increase was due to the acquisitions of
Ortel, Agere, Inc., Herrmann and substantially all the assets of VTC during
fiscal 2000.

     Amortization of goodwill and other acquired intangibles. Amortization
expense increased $176 million, to $189 million in fiscal 2000 from $13 million
in fiscal 1999. This increase reflects amortization of goodwill associated with
the acquisitions of Ortel, Herrmann and Agere, Inc. during fiscal 2000.

     Operating income (loss).  Operating income decreased 67%, or $323 million,
to $156 million in fiscal 2000 from $479 million in fiscal 1999. This was driven
primarily by purchased in-process research and development costs, an increase in
the amortization of goodwill and other acquired intangibles and an increase in
research and development cost, partially offset by an increase in gross profit.
Performance measurement and resource allocation for the reportable segments are
based on many factors. The primary financial measure used is operating income by
segment, exclusive of purchased in-process research and development costs and
                                        29

</Table>

     Other income-net.  Other income-net decreased 8%, or $3 million, to $33
million in fiscal 2000 from $36 million in fiscal 1999. The $33 million in
fiscal 2000 was comprised primarily of gains on sales of investments of $18
million, $4 million of equity income and a $6 million gain on foreign currency
transactions. The $36 million in fiscal 1999 was comprised primarily of gains on
sales of investments of $32 million, a $20 million equity loss and a $9 million
gain on foreign currency transactions.

     Provision for income taxes.  The effective tax rates were 158.0% and 33.1%
for fiscal 2000 and 1999, respectively. The increase in effective tax rates was
due to the fiscal 2000 write-offs of purchased in-process research and
development costs that are not deductible for tax purposes. Excluding the impact
of non-tax deductible purchased in-process research and development expenses and
amortization of goodwill and other acquired intangibles expenses, the effective
tax rates were 27.8% and 32.2% for fiscal 2000 and 1999, respectively. The
decrease was primarily due to the tax impact of non-U.S. activity and increased
research tax credits.

LIQUIDITY AND CAPITAL RESOURCES

     As of September 30, 2001, our net cash position was $636 million, which
reflects $3,152 million in cash and cash equivalents less $2,516 million of
short-term debt, including a $16 million current portion of capitalized lease
obligations. The $636 million of net cash is primarily the result of our receipt
of $3,448 million of net cash proceeds from our initial public offering, offset
by $2,500 million of short-term debt we assumed from Lucent at that time. We did
not receive any of the proceeds of this debt and Lucent was relieved of all
obligations related to this debt.

     Net cash provided by operating activities was $269 million in fiscal 2001
compared to $762 million for fiscal 2000. The decrease in fiscal 2001, compared
with fiscal 2000, reflects a reduction in revenues during a period in which we
increased our manufacturing capacity and infrastructure in anticipation of
higher revenues. The adverse impact on cash caused by our fiscal 2001 net loss
was offset by a $413 million reduction in accounts receivable and a $243 million
increase in accounts payable. In fiscal 2002, we expect the restructuring
initiatives announced in fiscal 2001 will reduce our cash needs. In addition, we
expect to announce additional actions during fiscal 2002 to further reduce our
costs, expenses and break-even point.

     Net cash provided by operating activities was $762 million in fiscal 2000
compared to $690 million for fiscal 1999. The improvement was primarily the
result of increases in net income, excluding the non-cash impact associated with
depreciation and amortization and purchased in-process research and development.
In fiscal 2000 our cash provided by operating activities reflects an increase in
receivables of $237 million as a result of increased revenue. In fiscal 1999 our
cash provided by operating activities reflects a pre-payment of certain costs in
connection with the expansion of our non-U.S. integrated circuits operations.

     Net cash used in investing activities was $723 million in fiscal 2001
compared to $829 million and $753 million in fiscal 2000 and 1999, respectively.
Capital expenditures and acquisitions of businesses have historically been the
primary components of our investing activities. Capital expenditures were $723
million, $672 million and $656 million in fiscal 2001, 2000 and 1999,
respectively. Our capital spending has been used primarily in support of our
manufacturing facilities. Capital spending also includes expenditures for
information technology, including computer servers and networking capability.
                                        30
<PAGE>

     In fiscal 2001 we invested $96 million on the construction of a new office
facility adjacent to our current headquarters and invested $24 million in
capital expenditures related to our separation from Lucent. The remainder of our
capital expenditures supported on-going business requirements. In light of
current business conditions, we are limiting our capital expenditures
principally to projects critical to winning new business or keeping customer
commitments. Our capital investment needs are expected to be significantly lower
in fiscal 2002 than in fiscal 2001, resulting from the current downturn in our
markets.

     Net cash provided by financing activities was $3,607 million in fiscal 2001
compared to $67 million and $63 million in fiscal 2000 and 1999, respectively.
The increase in fiscal 2001 was primarily the result of the receipt of the net
cash proceeds from the sale of our common stock in our initial public offering.
Prior to our initial public offering, we relied on Lucent to provide financing
for our operations.

     The $2,500 million credit facility that we assumed from Lucent at the time
of our initial public offering was a 364-day facility that was to mature on
February 21, 2002. On October 4, 2001, this credit facility was amended. In
connection with the amendment, we repaid $1,000 million of the $2,500 million
debt reducing the facility to $1,500 million. The facility is comprised of term
loans and revolving credit loans and is secured by our principal domestic assets
other than the proceeds of our initial public offering and while Lucent remains
a majority stockholder, real estate. The maturity date of the facility has been
extended from February 22, 2002 to September 30, 2002. In addition, if we raise
at least $500 million in equity or debt capital markets transactions before
September 30, 2002, the maturity date of the facility will be extended to
September 30, 2004, with the facility required to be reduced to $750 million on
September 30, 2002 and $500 million on September 30, 2003. The debt is not
convertible into any other securities of the company.

     The interest rates applicable to borrowings under the facility are based on
a scale indexed to our credit rating. Based upon our current credit ratings of
BB- from Standard & Poor's and Ba3 from Moody's, the interest rate under the
facility is currently the applicable LIBOR rate plus 475 basis points. In
addition, until we permanently reduce the size of the facility to $1,000 million
the applicable interest rate will increase by an additional 25 basis points
every ninety days, with the next increase taking effect on February 17, 2002. If
we permanently reduce the size of the facility to $1,000 million the interest
rate for borrowings under the facility, assuming our credit ratings remain the
same, would drop to the applicable LIBOR rate plus 400 basis points. The only
periodic debt service obligation under the amended credit facility is to make
quarterly interest payments.

     Under the agreement, we must use proceeds of certain liquidity raising
transactions, asset sales outside the ordinary course of business and capital
markets transactions to reduce the size of the facility. If we complete the
liquidity raising transactions or sell assets outside the ordinary course of
business, we must apply 100% (50% if the size of the facility is $500 million or
less) of the net cash proceeds we receive from the transactions to reduce the
size of the facility. The agreement also provides that 50% of the net cash
proceeds of the first $500 million and 75% (50% if the size of the facility is
$500 million or less) of the net cash proceeds greater than $500 million from
equity and debt capital markets transactions be applied to reduce the credit
facility. Notwithstanding the foregoing, we must apply 100% of net cash proceeds
over $1,000 million from the issuance of debt securities that are secured
equally with the credit facility to reduce the size of the credit facility.

     On December 7, 2001, we entered into an agreement to sell certain assets
and liabilities related to our FPGA business to Lattice Semiconductor
Corporation for $250 million in cash. The sale is expected to close in the
second quarter of fiscal 2002, subject to regulatory approval and other
customary closing conditions. The net cash proceeds from the sale will be used
to reduce our credit facility in accordance with the terms of the credit
facility agreement.

     The credit facility contains covenants that require us to: (i) maintain a
minimum level of liquidity, (ii) achieve a minimum level of earnings before
interest, taxes, depreciation and amortization computed in accordance with the
agreement each quarter, (iii) maintain a minimum level of net worth, and (iv)
limit capital expenditures. Other covenants restrict our ability to pay cash
dividends, incur indebtedness and invest cash in our subsidiaries and other
businesses.

                                        31
<PAGE>

     As of September 30, 2001, our primary source of liquidity was our cash and
cash equivalents. We believe this cash, together with cash flow from operations,
will be sufficient to meet our cash requirements at least through the end of
fiscal 2002, including repayment of borrowings under the credit facility if its
maturity is not extended. If our revenues are materially lower than what is
contemplated in our outlook, we will further reduce expenditures in an effort to
meet our cash requirements. We also intend to seek additional funds from
liquidity generating transactions and capital markets financings, although we
cannot provide any assurance that any of these transactions or financings will
be available to us on acceptable terms or at all.

PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT

     In connection with the acquisitions of Agere, Inc., Herrmann, Ortel and
substantially all the assets of VTC in fiscal 2000, and the acquisitions of
Enable and Sybarus in fiscal 1999, a portion of each purchase price was
allocated to purchased in-process research and development. In analyzing these
acquisitions, we made decisions to buy technology that had not yet been
commercialized rather than develop the technology internally. We relied on
factors such as the amount of time it would take to bring the technology to
market in making these decisions. We also considered Lucent's Bell Laboratories'
resource allocation and its progress on comparable technology, if any. Our
management expects to use a similar decision process in the future.

     We estimated the fair value of in-process research and development for the
above acquisitions using an income approach. This involved estimating the fair
value of the in-process research and development using the present value of the
estimated after-tax cash flows expected to be generated by the purchased
in-process research and development, using risk-adjusted discount rates and
revenue forecasts as appropriate. The selection of the discount rate was based
on consideration of Lucent's weighted average cost of capital, as well as other
factors known at the time, including the projected useful life of each
technology, profitability levels of each technology, the uncertainty of
technology advances and the stage of completion of each technology. We believe
that the estimated in-process research and development amounts so determined
represented fair value and did not exceed the amount a third party would have
paid for the projects.

     Core technology is a product, service or process that exists at the date of
the acquisition and may contribute to the value of any product resulting from
in-process research and development. We deducted an amount representing the
estimated value of any core technology's contribution from the estimated cash
flows used to value in-process research and development. At the date of
acquisition, the in-process research and development projects had not yet
reached technological feasibility and had no alternative future uses.
Accordingly, the value allocated to these projects was capitalized and
immediately expensed at acquisition. If the projects are not successful or
completed in a timely manner, management's product pricing and growth rates may
not be achieved and we may not realize the financial benefits expected from the
projects.

     Set forth below are descriptions of the major acquired in-process research
and development projects and our original assumptions in connection with our
significant acquisitions, followed by a current status of the projects. Due to
significant changes in economic, industry and market conditions, particularly in
the latter half of fiscal 2001, the original assumptions at the time of
acquisition, for some of our acquisitions, vary materially from our current
estimates as noted below.

  AGERE, INC.

     On April 20, 2000, we completed the acquisition of Agere, Inc., which was a
developer and supplier of integrated circuits solutions used in network
processors, which control how data is sent over networks. At the acquisition
date, Agere, Inc. was conducting development and qualification activities
related to the development of a programmable network processor for various
protocols for 2.5 gigabits per second transmission speeds. A protocol is a set
of procedures for the formatting and timing of data transmission between two
pieces of equipment. A gigabit is a unit of measurement of data and is equal to
roughly one billion bits. The allocation to purchased in-process research and
development of $94 million represented its estimated fair value using the
methodology described above.

     Agere, Inc.'s in-process research and development projects were
approximately 65% complete at the time of acquisition. The projects were
expected to be completed in November 2000 after approximately two years of
research and development effort. Following completion, the projects were
expected to begin generating economic benefits. Revenue attributable to the
resulting products was estimated to be $21 million in fiscal
                                        32
<PAGE>

2001 and $65 million in fiscal 2002. Revenue was expected to peak in fiscal 2007
and decline thereafter through the end of the product's life, which was expected
to be in fiscal 2009, as new product technologies were expected to be introduced
by us. Revenue growth was expected to decrease from 205% in fiscal 2002 to 5% in
fiscal 2007 and be negative for the remainder of the projection period. At the
acquisition date, costs to complete Agere's in-process research and development
were expected to total approximately $3.4 million. Projected future net cash
flows attributable to Agere's in-process research and development, assuming
successful development, were discounted to net present value using a discount
rate of 30%.

     Most of Agere, Inc.'s in-process research and development projects were
completed in fiscal 2001. Due to significant changes in economic, industry and
market conditions, demand for these products has decreased and revenues
generated from these products are expected to be significantly lower than
originally anticipated.

  ORTEL CORPORATION

     On April 27, 2000, we completed the acquisition of Ortel, which was a
developer and manufacturer of semiconductor-based optoelectronic components used
in fiber optic systems for data communications and cable television networks. At
the acquisition date, Ortel was conducting development, engineering and testing
activities associated with high-speed optical transmitters, receivers and
transceivers.

     Ortel's in-process research and development projects ranged from 50% to 75%
complete at the time of acquisition. Ortel's in-process research and development
projects were expected to be completed during the period from June 2000 to April
2001 after approximately two to three and a half years of research and
development effort. Following completion, the projects were expected to begin
generating economic benefits. The allocation to purchased in-process research
and development of $307 million represented its estimated fair value using the
methodology described above. The $307 million was allocated to the following
projects, which are explained below.

     - 10G New Products -- $61 million;

     - 10G OC-192 Receiver/Daytona Products -- $105 million;

     - 980 Products -- $95 million;

     - 1550 Products -- $27 million; and

     - CATV Products -- $19 million.

     Projected net cash flows attributable to Ortel's in-process research and
development, assuming successful development, were discounted to net present
value using a discount rate of 25%.

     Revenue attributable to the 10G New Products was estimated to be $5 million
in fiscal 2001 and $30 million in fiscal 2002. 10G New Products are receivers
that incorporate new packaging technologies for high-speed transport and
metropolitan network applications at speeds of 10 gigabits per second. Revenue
was expected to peak in 2009 and decline thereafter through the end of the
products' life as new product technologies were expected to be introduced by us.
Revenue growth was expected to decrease from 447% in fiscal 2002 to 8% in fiscal
2009, and be negative for the remainder of the projection period. At the
acquisition date, costs to complete the research and development efforts related
to the products were expected to be $3 million.

     Revenue attributable to the 10G OC-192 Receiver/Daytona Products was
estimated to be $16 million in fiscal 2001 and $33 million in fiscal 2002. 10G
OC-192 Receiver/Daytona Products are directly modulated lasers and receivers
used for high-speed transport and metropolitan network applications at speeds of
10 gigabits per second. Revenue was expected to peak in fiscal 2009 and decline
thereafter through the end of the products' life as new product technologies
were expected to be introduced by us. Revenue growth was expected to decrease
from 166% in fiscal 2003 to 8% in fiscal 2009, and be negative for the remainder
of the projection period. At the acquisition date, costs to complete the
research and development efforts related to the product were expected to be $1
million.

     Revenue attributable to the 980 Products was estimated to be $44 million in
fiscal 2001 and $108 million in fiscal 2002. 980 Products are pump lasers
operating at 980 nanometers wavelength. A nanometer is a unit of measurement of
distance and equals one billionth of a meter. Revenue was expected to peak in
2008 and decline thereafter through the end of the products' life as new product
technologies were expected to be
                                        33

introduced by us. Revenue growth was expected to decrease from 143% in 2002 to
17% in 2008, and be negative for the remainder of the projection period. At the
acquisition date, costs to complete the research and development efforts related
to the 980 Products were expected to be $1 million.

     Revenue attributable to the 1550 Products was estimated to be $2 million in
fiscal 2001 and $63 million in fiscal 2002. 1550 Products are transmitters and
lasers operating at 1550 nanometers wavelength. Revenue was expected to peak in
2008 and decline thereafter through the end of the products' life as new product
technologies were expected to be introduced by us. Revenue growth was expected
to decrease from 33% in 2003 to 17% in fiscal 2008, and be negative for the
remainder of the projection period. At the acquisition date, costs to complete
the research and development efforts related to the 1550 Products were expected
to be $2 million.

     Revenue attributable to the CATV Products was estimated to be $28 million
in fiscal 2001 and $58 million in fiscal 2002. CATV Products are receivers and
return path products for cable television network applications. The return path
allows cable system operators to offer Internet and telephone services, in
direct competition with network services providers. Revenue was expected to peak
in fiscal 2004 and decline thereafter through the end of the products' life as
new product technologies were expected to be introduced by us. Revenue growth
was expected to decrease from 107% in fiscal 2002 to 4% in fiscal 2004 and be
negative for the remainder of the projection period. At the acquisition date,
costs to complete the research and development efforts related to the CATV
Products were expected to be $1 million.

     Development of Ortel's most significant products was completed in fiscal
2001. Certain other Ortel products remain under development, with completion
anticipated during fiscal 2002. Due to significant changes in economic, industry
and market conditions, demand for Ortel's products has decreased and revenues
generated from these products are expected to be significantly lower than
originally anticipated.

  HERRMANN TECHNOLOGY, INC.

     On June 16, 2000, we completed the acquisition of Herrmann, which was a
developer and supplier of passive optical filters that can be used in
conjunction with active optoelectronic components in products such as
amplifiers. The allocation to in-process research and development of $34 million
represented its estimated fair value using the methodology described above. The
$34 million was allocated primarily to the development of manufacturing
processes.

     Revenue attributable to the products using these manufacturing processes
was estimated to be $59 million in fiscal 2001 and $91 million in fiscal 2002.
Revenue was expected to peak in fiscal 2005 and decline thereafter through the
end of the products' life as new technologies were expected to be introduced by
us. Revenue growth was expected to decrease from 54.7% in 2002 to 0.7% in fiscal
2005, and be negative for the remainder of the projection period. At the
acquisition date, costs to complete the research and development efforts related
to the processes were expected to be $0.5 million.

     Herrmann's in-process research and development projects ranged from 20% to
60% complete at the time of acquisition. Herrmann's in-process research and
development projects were expected to be completed during the period from August
2000 to June 2001 after approximately two to six years of research and
development effort. Following completion, the projects were expected to begin
generating economic benefits. In total, costs to complete Herrmann's in-process
research and development were expected to equal approximately $1.8 million.
Projected future net cash flows attributable to Herrmann's in-process research
and development, assuming successful development, were discounted to net present
value using a discount rate of 27.5%.

     Herrmann's in process research and development processes were either
completed or discontinued due to market conditions during fiscal 2001. Due to
significant changes in economic, industry and market conditions, demand for
products which use these processes has decreased and revenues generated from
these products are expected to be significantly lower than originally
anticipated.

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

     We are subject to a wide range of laws and regulations relating to
protection of the environment and employee safety and health. We are currently
involved in investigations and/or cleanup of known contamination at eight sites
either voluntarily or pursuant to government directives. There are established
reserves for environmental liabilities where they are probable and reasonably
estimable. Reserves for estimated losses from environmental remediation are,
depending on the site, based primarily upon internal or third party
environmental studies, estimates as to the number, participation level and
financial viability of all potential responsible parties, the extent of
contamination and the nature of required remedial actions. Although we believe
that the reserves are adequate to cover known environmental liabilities, it is
often difficult to estimate with certainty the future cost of such matters.
Therefore, there is no assurance that expenditures that will be required
relating to remedial actions and compliance with applicable environmental laws
will not exceed the amount reflected in the reserves for such matters or will
not have a material adverse effect on our consolidated financial condition,
results of operations or cash flows.

LEGAL PROCEEDINGS

     From time to time we are involved in legal proceedings arising in the
ordinary course of business, including unfair labor charges filed by our unions
with the National Labor Relations Board, claims before the U.S. Equal Employment
Opportunity Commission and other employee grievances. We also may be subject to
intellectual property litigation and infringement claims, which could cause us
to incur significant expenses or prevent us from selling our products.

     On October 3, 2000, a patent infringement lawsuit was filed against Lucent,
among other optoelectronic components manufacturers, by Litton Systems, Inc. and
The Board of Trustees of the Leland Stanford Junior University in the United
States District Court for the Central District of California (Western Division).
We anticipate we may be named a defendant in the suit. The complaint alleges
that each of the defendants is infringing a patent related to the manufacture of
erbium-doped optical amplifiers. The patent is owned by Stanford University and
is exclusively licensed to Litton. The complaint seeks, among other remedies,
unspecified monetary damages, counsel fees and injunctive relief. This matter is
in its early stages.

     An investigation was commenced on April 4, 2001, by the U.S. International
Trade Commission based on a request of Proxim, Inc. alleging patent infringement
by 14 companies, including some of our customers for wireless local area
networking products. Proxim alleges infringement of three patents related to
spread-spectrum coding techniques. Spread-spectrum coding techniques refers to a
way of transmitting a signal for wireless communications by spreading the signal
over a wide frequency band. We believe we have valid defenses to Proxim's claims
and have intervened in the investigation in order to defend our customers.
Proxim seeks relief in the form of an exclusion order preventing the importation
of specified wireless local area networking products, including some of our
products, into the United States. One of our subsidiaries, Agere Systems
Guardian Corp., filed a lawsuit on May 23, 2001, in the U.S. District Court in
Delaware against Proxim alleging infringement of three patents used in Proxim's
wireless local area networking products.

     If we are unsuccessful in resolving these proceedings, as they relate to
us, our operations may be disrupted or we may incur additional costs. Other than
as described above, we do not believe there is any litigation pending that
should have, individually or in the aggregate, a material adverse effect on our
consolidated financial position, results of operations or cash flows.

RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets."
Statement 142 provides guidance on the financial accounting and reporting for
acquired goodwill and other intangible assets. Under Statement 142, goodwill and
indefinite lived intangible assets will no longer be amortized but will be
reviewed for impairment at least annually and subject to new impairment tests.
Intangible assets with finite lives will continue to be amortized over their
useful lives but will no longer be limited to a maximum life of forty years.
Statement 142 is effective for Agere in fiscal year 2003, although earlier
application is permitted. We plan to adopt
                                        35
<PAGE>

Statement 142 effective October 1, 2002 and are currently evaluating the
potential effects of implementing this standard on our financial condition and
results of operations.

     Also in July 2001, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 143, "Accounting for Asset
Retirement Obligations." Statement 143 addresses financial accounting and
reporting for legal obligations associated with the retirement of tangible
long-lived assets and their associated retirement costs. In accordance with
Statement 143, retirement obligations will be recognized at fair value in the
period they are incurred. When the liability is initially recorded, the cost
will be capitalized by increasing the asset's carrying value, which is
subsequently depreciated over its useful life. Statement 143 is effective for
Agere in fiscal year 2003, with earlier application encouraged. We are currently
evaluating the potential effects, if any, on our financial condition and results
of operations of adopting Statement 143, as well as the timing of its adoption.

     In October 2001, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." This Statement primarily addresses financial
accounting and reporting for the impairment or disposal of long-lived assets and
also affects certain aspects of accounting for discontinued operations.
Statement 144 is effective for Agere in fiscal year 2003, with earlier
application encouraged. We are currently evaluating the potential effects, if
any, on our financial condition and results of operations of adopting Statement
144, as well as the timing of its adoption.

EUROPEAN MONETARY UNION -- EURO

     Several member countries of the European Union have established fixed
conversion rates between their existing sovereign currencies and the Euro, and
have adopted the Euro as their new single legal currency. The legacy currencies
will remain legal tender in the participating countries for a transition period
between January 1, 1999 and January 1, 2002. During the transition period,
cash-less payments can be made in the Euro. Between January 1, 2002 and February
28, 2002, the participating countries will introduce Euro notes and coins and
withdraw all legacy currencies so that they will no longer be available. The
Euro conversion may affect cross-border competition by creating cross-border
price transparency. We will continue to evaluate issues involving introduction
of the Euro as further accounting, tax and governmental legal and regulatory
guidance is available. Based on current information and our current assessment,
it is not expected that the Euro conversion will have a material adverse effect
on our business or financial condition.

FACTORS AFFECTING OUR FUTURE PERFORMANCE

     Set forth below and elsewhere in this Form 10-K and in other documents we
file with the Securities and Exchange Commission are risks and uncertainties
that could cause actual results to differ materially from the results
contemplated by the forward-looking statements contained in this Form 10-K.

RISKS RELATED TO OUR SEPARATION FROM LUCENT

WE WILL BE CONTROLLED BY LUCENT AS LONG AS IT OWNS A MAJORITY OF OUR COMMON
STOCK, AND OUR OTHER STOCKHOLDERS WILL BE UNABLE TO AFFECT THE OUTCOME OF
STOCKHOLDER VOTING DURING THAT TIME.

     Lucent is our controlling stockholder because it owns more than a majority
of our common stock. Because Lucent's interests may differ from ours, actions
Lucent takes with respect to us, as our controlling stockholder, may not be
favorable to us.

     Lucent's interests may not be the same as, or may conflict with, the
interests of our other stockholders. Our other stockholders will not be able to
affect the outcome of any stockholder vote so long as Lucent owns a majority of
our common stock.

     Lucent is generally not prohibited from selling a controlling interest in
us to a third party. Because we have elected not to be subject to Section 203 of
the General Corporation Law of the State of Delaware, Lucent, as a controlling
stockholder, may find it easier to sell its controlling interest to a third
party than if we were subject to Section 203.
                                        36
<PAGE>

THE TIMING AND MANNER OF OUR SEPARATION FROM LUCENT ARE UNCLEAR AND MAY NOT
OCCUR, AND WE MAY NOT ACHIEVE MANY OF THE EXPECTED BENEFITS OF OUR SEPARATION,
SO WE MAY LOSE MANY OF OUR EMPLOYEES AND OUR BUSINESS MAY SUFFER.

     We believe that the announcement of our separation from Lucent led to an
increased interest in doing business with us from some of our existing and
potential customers. If the distribution of all shares of our common stock that
Lucent owns to its stockholders does not occur, then these customers may not
increase or commence purchases of our products. Many of our existing employees
are anticipating our spin off from Lucent and may be more susceptible to
competitive job offers if the distribution does not occur or is delayed. We also
may not obtain some of the other benefits we expect as a result of this
distribution, including greater strategic focus and increased agility and speed.
Further, even if the distribution occurs, we may not achieve the benefits of our
separation. In addition, until the distribution occurs, the risks relating to
Lucent's control of us and the potential business conflicts of interest between
Lucent and us will continue to be relevant to our stockholders.

WE MAY HAVE POTENTIAL BUSINESS CONFLICTS OF INTEREST WITH LUCENT WITH RESPECT TO
OUR PAST AND ONGOING RELATIONSHIPS AND, BECAUSE OF LUCENT'S CONTROLLING
OWNERSHIP, THE RESOLUTION OF THESE CONFLICTS MAY NOT BE ON THE MOST FAVORABLE
TERMS TO US.

     Prior to the distribution, a resolution of any potential conflicts of
interest between Lucent and us may be less favorable to us than if we were
dealing with an unaffiliated party. Conflicts of interest may arise between
Lucent and us in a number of areas relating to our past and ongoing
relationships, including:

     - the nature, quantity, quality, time of delivery and pricing of products
       we supply to each other under, and other issues arising under, our
       product purchase agreements with Lucent;

     - labor, tax, employee benefit, indemnification and other matters arising
       from our separation from Lucent;

     - intellectual property matters;

     - employee recruiting and retention;

     - sales or distributions by Lucent of all or any portion of its ownership
       interest in us, which could be to one of our competitors; and

     - business opportunities that may be attractive to both Lucent and us.

     We and Lucent have entered into several agreements in connection with our
separation, as described in note 19 to our financial statements in Item 8. While
we are controlled by Lucent, it is possible for Lucent to cause us to amend
these agreements on terms that may be less favorable to us than the current
terms of the agreements.

OUR HISTORICAL FINANCIAL INFORMATION PRIOR TO THE FEBRUARY 1, 2001 CONTRIBUTION
TO US OF OUR BUSINESS FROM LUCENT MAY NOT BE REPRESENTATIVE OF OUR RESULTS AS A
STAND-ALONE COMPANY AND, THEREFORE, MAY NOT BE RELIABLE AS AN INDICATOR OF OUR
HISTORICAL OR FUTURE RESULTS.

     Our historical combined and consolidated financial statements may not be
indicative of our future performance as a stand-alone company. This is primarily
a result of the three factors described below.

     - First, our historical combined and consolidated financial statements
       reflect allocations, primarily with respect to general corporate
       expenses, research expense and interest expense, which may be less than
       the expenses we will incur in the future as a stand-alone company.

     - Second, the information does not reflect significant changes that we
       expect to occur in the future as a result of our separation from Lucent,
       including changes in how we fund our operations, conduct research and
       handle tax and employee matters.

                                        37
<PAGE>

     - Third, our historical combined and consolidated financial statements
       include substantial revenue from sales to Lucent. This revenue may not
       reflect the pricing, volume or percentage of our sales we would have
       derived from Lucent if we were a stand-alone company.

WE HAVE A SIGNIFICANT AMOUNT OF DEBT, WHICH SUBJECTS US TO VARIOUS RESTRICTIONS
AND INTEREST COSTS, AND WE MAY SUBSTANTIALLY INCREASE OUR DEBT IN THE FUTURE.

     Because Lucent historically provided financing to us and incurred debt at
the parent level, our historical combined balance sheets do not include debt. On
April 2, 2001, upon completion of our initial public offering, we assumed $2.5
billion of short-term debt that Lucent had borrowed under a credit facility. We
did not receive any of the proceeds from the credit facility. Lucent was
relieved of all obligations related to this short-term debt. On October 4, 2001,
we amended and restated the credit agreement governing the credit facility and
in connection therewith permanently repaid $1.0 billion of borrowings under the
credit facility. See "Item 7 -- Liquidity and Capital Resources" for a
description of the credit facility.

     We may substantially increase our debt in the future.  If our cash flow
from operations is less than we expect, we may require more financing. We may
from time to time issue additional debt, borrow funds under revolving credit
facilities or issue other long- or short-term debt.

BECAUSE LUCENT'S BELL LABORATORIES' CENTRAL RESEARCH ORGANIZATION HISTORICALLY
PERFORMED IMPORTANT RESEARCH FOR US, WE WILL NEED TO DEVELOP OUR OWN CORE
RESEARCH CAPABILITY. WE MAY NOT BE SUCCESSFUL, WHICH COULD MATERIALLY HARM OUR
PROSPECTS AND ADVERSELY AFFECT OUR RESULTS OF OPERATIONS.

     If our separate research efforts are not as successful as when we were part
of Lucent, we may not be able to keep pace with the rapid technological change
in our industry and our prospects may be harmed. Many of our products use
technology and manufacturing processes derived from innovations developed by
Lucent's Bell Laboratories central research organization. After the contribution
to us of our business in February 2001, Lucent has no obligation to provide
research and development for us except as agreed to in the development project
agreement and joint design center operating agreement described under note 19 to
our financial statements in Item 8. We cannot assure you that our independent
research efforts will be as successful as the efforts of Bell Laboratories have
been historically or that our efforts will not require us to increase our
expenditures for the same services over the amounts in our historical combined
and consolidated financial statements. A significant increase in our
expenditures for the same services may adversely affect our results of
operations. We may not be able to recruit engineers and other research and
development employees as effectively as Bell Laboratories was able to because of
its history, name recognition and size.

MANY OF OUR EXECUTIVE OFFICERS AND SOME OF OUR DIRECTORS MAY HAVE CONFLICTS OF
INTEREST BECAUSE OF THEIR OWNERSHIP OF LUCENT COMMON STOCK AND OTHER TIES TO
LUCENT.

     Many of our executive officers and some of our directors, including the
Lucent-appointed directors who we expect will resign at the time of the
distribution, have a substantial amount of their personal financial portfolios
in Lucent common stock and options to purchase Lucent common stock. Ownership of
Lucent common stock or options to purchase Lucent common stock by our directors
and officers could create, or appear to create, potential conflicts of interest
when directors and officers are faced with decisions that could have different
implications for Lucent and us.

WE COULD INCUR SIGNIFICANT TAX LIABILITY IF LUCENT FAILS TO PAY THE TAX
LIABILITIES ATTRIBUTABLE TO LUCENT UNDER OUR TAX SHARING AGREEMENT, WHICH COULD
REQUIRE US TO PAY A SUBSTANTIAL AMOUNT OF MONEY.

     We and Lucent have entered into a tax sharing agreement that allocates
responsibility for tax liabilities between us and them. Under U.S. federal
income tax laws, we and Lucent are jointly and severally liable for Lucent's
federal income taxes attributable to periods prior to and including the most
recent taxable year of Lucent, which ended on September 30, 2001. This means
that if Lucent fails to pay the taxes attributable to it under the tax sharing
agreement for those periods, we may be liable for any part of, including the
whole amount of, these liabilities.

                                        38
<PAGE>

BECAUSE THE DIVISION OF ENFORCEMENT OF THE SECURITIES AND EXCHANGE COMMISSION IS
INVESTIGATING MATTERS BROUGHT TO ITS ATTENTION BY LUCENT, OUR BUSINESS MAY BE
AFFECTED IN A MANNER WE CANNOT FORESEE AT THIS TIME.

     On November 21, 2000, and again on December 21, 2000, Lucent brought to the
attention of the staff of the Securities and Exchange Commission matters
relating to its recognition of revenue. Lucent also publicly disclosed these
matters in press releases on those dates. Although Lucent has informed us that
it has no reason to believe that this investigation by the Division of
Enforcement of the Securities and Exchange Commission into these matters
concerns our business and we are not aware of any reason why the investigation
would affect us, it is possible that the results of the investigation may have
an impact on us. Although the investigation could result in no action being
taken by the Securities and Exchange Commission, if an action is taken and the
investigation is found to concern our business, the action could result in
monetary fines or changes in some of our financial and other practices and
procedures that we are unable to foresee at this time.

RISKS RELATED TO OUR BUSINESS

THE DEMAND FOR PRODUCTS IN OUR INDUSTRY HAS RECENTLY DECLINED, AND WE CANNOT
PREDICT THE DURATION OR EXTENT OF THIS TREND.

     We believe that deteriorating economic conditions have caused less spending
on communications networks and weakness in our customers' markets. As a result
of the uncertainties in our customers' demand forecasts and ordering patterns,
we cannot predict the duration or extent of the decline of demand for our
products. If demand in our industry continues to decline, our revenue is likely
to decline.

IF WE DO NOT COMPLETE OUR ANNOUNCED WORKFORCE REDUCTIONS AND OTHER RESTRUCTURING
ACTIVITIES AS EXPECTED OR EVEN IF WE DO SO, WE MAY NOT ACHIEVE ALL OF THE
EXPENSE REDUCTIONS WE ANTICIPATE.

     In the third quarter of fiscal 2001, we announced a series of restructuring
initiatives to align Agere with current market conditions. These initiatives are
focused on improving gross profit, reducing expenses and streamlining
operations. These restructuring initiatives include a worldwide workforce
reduction, rationalization of manufacturing capacity, impairment of goodwill and
other restructuring charges. If we do not complete these workforce reductions
and other restructuring activities as expected or even if we do so, we may not
achieve all of the expense reductions we anticipate. Because our revenue has
declined since we announced these initiatives, we expect to implement further
restructuring activities, which will be subject to the same uncertainty.

BECAUSE SALES OF OUR INTEGRATED CIRCUITS AND OPTOELECTRONIC COMPONENTS ARE
DEPENDENT ON THE GROWTH OF COMMUNICATIONS NETWORKS, AS MARKET DEMAND FOR THESE
NETWORKS DECLINES, PARTICULARLY FOR OPTICAL NETWORKS, OUR REVENUE IS LIKELY TO
DECLINE.

     We derive, and expect to continue to derive, a significant amount of
revenue from the sale of integrated circuits and optoelectronic components used
in optical, wired and wireless communications networks. If the long-term growth
in demand for these communications networks does not occur as we expect, the
demand for many of our integrated circuits and optoelectronic components may
decline or grow more slowly than we expect. As a result, we may not be able to
grow our business and our revenue may decline from current levels.

IF WE FAIL TO KEEP PACE WITH TECHNOLOGICAL ADVANCES IN OUR INDUSTRY OR IF WE
PURSUE TECHNOLOGIES THAT DO NOT BECOME COMMERCIALLY ACCEPTED, CUSTOMERS MAY NOT
BUY OUR PRODUCTS AND OUR REVENUE MAY DECLINE.

     The demand for our products can change quickly and in ways we may not
anticipate because our industry is generally characterized by:

     - rapid, and sometimes disruptive, technological developments;

     - evolving industry standards;

     - changes in customer requirements;

     - limited ability to accurately forecast future customer orders;

     - frequent new product introductions and enhancements; and

     - short product life cycles with declining prices over the life cycle of
       the product.

                                        39
<PAGE>

     If we fail to make sufficient investments in research and development
programs in order to develop new and enhanced products and solutions, or if we
focus on technologies that do not become widely adopted, new technologies could
render our current and planned products obsolete, resulting in the need to
change the focus of our research and development and product strategies and
disrupting our business significantly.

BECAUSE OUR SALES ARE CONCENTRATED ON LUCENT AND A FEW OTHER CUSTOMERS, OUR
REVENUE MAY MATERIALLY DECLINE IF ONE OR MORE OF OUR KEY CUSTOMERS DO NOT
CONTINUE TO PURCHASE OUR EXISTING AND NEW PRODUCTS IN SIGNIFICANT QUANTITIES.

     Our customer base is highly concentrated. Our top ten end customers
accounted for approximately 53% of our revenue in fiscal 2001. If any one of our
key customers decides to purchase significantly less from us or to terminate its
relationship with us, our revenue may materially decline. Because our strategy
has generally been to develop long-term relationships with a few key customers
in the product areas in which we focus and we have a long product design and
development cycle for most of our products, we may be unable to replace these
customers quickly or at all. We could lose our key customers or significant
sales to our key customers because of factors beyond our control, such as a
significant disruption in our customers' businesses generally or in a specific
product line.

     In particular, we depend on Lucent as a key customer. We derived 14.9% of
our revenue from sales to Lucent in fiscal 2001. We expect to continue to be
dependent on Lucent for a significant percentage of our revenue.

IF WE ARE UNABLE TO EXTEND OR REFINANCE OUR CREDIT FACILITY, WE MAY NOT HAVE
SUFFICIENT CASH AVAILABLE TO REPAY THAT FACILITY WHEN IT MATURES ON SEPTEMBER
30, 2002.

     We cannot assure you that we will be able to extend or refinance our credit
facility before it matures on September 30, 2002. We may not be able to raise
funds to repay the facility, or obtain an alternative credit facility, on
favorable terms or at all. See "Item 7 -- Liquidity and Capital Resources" for
additional information about our credit facility.

IF WE FAIL TO ATTRACT, HIRE AND RETAIN QUALIFIED PERSONNEL, WE MAY NOT BE ABLE
TO DEVELOP, MARKET OR SELL OUR PRODUCTS OR SUCCESSFULLY MANAGE OUR BUSINESS.

     In some fields, there are only a limited number of people in the job market
with the requisite skills, particularly people with optoelectronic technology
expertise. We have in the past experienced difficulty in identifying and hiring
qualified engineers in many areas of our business as well as in retaining our
current employees. The loss of the services of any key personnel or our
inability to hire new personnel with the requisite skills could restrict our
ability to develop new products or enhance existing products in a timely manner,
sell products to our customers or manage our business effectively.

OUR PRODUCTS AND TECHNOLOGIES TYPICALLY HAVE LENGTHY DESIGN AND DEVELOPMENT
CYCLES. A CUSTOMER MAY DECIDE TO CANCEL OR CHANGE ITS PRODUCT PLANS, WHICH COULD
CAUSE US TO GENERATE NO REVENUE FROM A PRODUCT AND ADVERSELY AFFECT OUR RESULTS
OF OPERATIONS.

     We may never generate any revenue from our products after incurring
significant design and development expenditures. A delay or cancellation of a
customer's plans could significantly adversely affect our financial results.
Unlike some of our competitors, we primarily focus on winning competitive
selection processes to develop products for use in our customers' equipment.
These selection processes can be lengthy. After winning and beginning a product
design for one of our customers, that customer may not begin volume production
of their equipment for a period of up to two years, if at all. Due to this
lengthy design and development cycle, we may experience delays from the time we
begin incurring expenses until the time we generate revenue from our products.
We have no assurances that our customers will ultimately market and sell their
equipment or that such efforts by our customers will be successful.

                                        40
<PAGE>

BECAUSE WE ARE SUBJECT TO ORDER AND SHIPMENT UNCERTAINTIES, ANY SIGNIFICANT
CANCELLATIONS OR DEFERRALS COULD CAUSE OUR REVENUE TO DECLINE OR FLUCTUATE.

     We generally sell products pursuant to purchase orders that customers may
cancel or defer on short notice without incurring a significant penalty.
Cancellations or deferrals could cause us to hold excess inventory, which could
adversely affect our results of operations and restrict our ability to fund our
operations. If a customer cancels or defers product shipments, we may incur
unanticipated reductions or delays in our revenue. If a customer refuses to
accept shipped products or does not timely pay for these products, we could
incur significant charges against our income, which could materially and
adversely affect our operating results.

WE DEPEND ON SOME SINGLE SOURCES OF SUPPLY, PARTICULARLY FOR OUR OPTOELECTRONIC
COMPONENTS, AND INTERRUPTIONS AFFECTING THESE AND OTHER SUPPLIERS COULD DISRUPT
OUR PRODUCTION, COMPROMISE OUR PRODUCT QUALITY AND CAUSE OUR REVENUE TO DECLINE.

     We depend on a single source supplier for several different parts used to
make some of our optoelectronic components. Some of these single source
suppliers also are competitors of ours. In some of these cases, there is no
qualified alternative supplier for these parts or processes and qualifying new
suppliers could require a substantial lead time. The loss of any of these or
other significant suppliers or the inability of a supplier to meet performance
and quality specifications or delivery schedules could cause our revenue to
significantly decline.

BECAUSE WE EXPECT TO CONTINUE TO DERIVE A MAJORITY OF OUR REVENUE FROM
INTEGRATED CIRCUITS AND THE INTEGRATED CIRCUITS INDUSTRY IS HIGHLY CYCLICAL, OUR
REVENUE MAY FLUCTUATE.

     We expect to continue to derive a majority of our revenue from integrated
circuits products. Because the integrated circuits market segment is highly
cyclical, we may have declines in our revenue that are primarily related to
industry conditions and not our products. This market segment has experienced
significant downturns, often in connection with, or in anticipation of, excess
manufacturing capacity worldwide, maturing product cycles and declines in
general economic conditions, and we are currently experiencing such a downturn.
Downturns are characterized by diminished product demand and production
overcapacity, as well as high inventory levels and accelerated erosion of
average selling prices.

IF WE DO NOT ACHIEVE ADEQUATE MANUFACTURING UTILIZATION, YIELDS, VOLUMES OR
SUFFICIENT PRODUCT RELIABILITY, OUR GROSS MARGINS WILL BE REDUCED.

     Because the majority of our manufacturing costs are relatively fixed,
efficient utilization of manufacturing facilities and manufacturing yields are
critical to our results of operations. Some of our manufacturing facilities have
been underutilized, which has reduced our gross margins. Lower than expected
manufacturing yields could impair our gross margins and delay product shipments.

     In the event of an increase in demand, failure to increase our
manufacturing volumes to meet our customers' increasing needs and satisfy
customer demand will have a significant effect on our gross margins. In some
cases, existing manufacturing capacity may be insufficient to achieve the volume
or cost targets of our customers.

     The manufacture of our products involves highly complex and precise
processes, requiring production in highly controlled and clean environments.
Changes in our manufacturing processes or those of our suppliers or contractors,
or their inadvertent use of defective or contaminated materials, could
significantly reduce our manufacturing yields and product reliability.

WE HAVE RELATIVELY HIGH GROSS MARGIN ON THE REVENUE WE DERIVE FROM THE LICENSING
OF OUR INTELLECTUAL PROPERTY, AND A DECLINE IN THIS REVENUE WOULD HAVE A GREATER
IMPACT ON OUR NET INCOME THAN A DECLINE IN REVENUE FROM OUR INTEGRATED CIRCUITS
AND OPTOELECTRONIC PRODUCTS.

     The revenue we generate from the licensing of our intellectual property has
a high gross margin compared to the revenue we generate from our integrated
circuits and optoelectronic products. A decline in this licensing revenue will
have a greater impact on our profitability than a similar decline in revenues
from our integrated circuits and optoelectronic products.

                                        41
<PAGE>

     WE DEPEND ON JOINT VENTURES OR OTHER THIRD-PARTY STRATEGIC RELATIONSHIPS
FOR THE MANUFACTURE OF SOME OF OUR PRODUCTS, ESPECIALLY INTEGRATED CIRCUITS. IF
THESE MANUFACTURERS ARE UNABLE TO FILL OUR ORDERS ON A TIMELY AND RELIABLE
BASIS, OUR REVENUE MAY DECLINE.

     We currently manufacture our integrated circuits and optoelectronic
components through a combination of internal capability, joint ventures and
external sourcing with contract manufacturers. To the extent we rely on joint
ventures and third-party manufacturing relationships, especially with respect to
integrated circuits, we face the following risks:

     - their inability to develop manufacturing methods appropriate for our
       products;

     - that the manufacturing costs will be higher than planned;

     - that the reliability of our products will decline;

     - their unwillingness to devote adequate capacity to produce our products;

     - their inability to maintain continuing relationships with our suppliers;
       and

     - the reduction of our control over delivery schedules and costs of our
       products.

     If any of these risks is realized, we could experience an interruption in
supply or an increase in costs, which could delay or decrease our revenue or
adversely affect our results of operations.

IF OUR CUSTOMERS DO NOT QUALIFY OUR MANUFACTURING LINES FOR VOLUME SHIPMENTS,
OUR REVENUE MAY BE DELAYED OR REDUCED.

     Customers will not purchase any of our products, other than limited numbers
of evaluation units, prior to qualification of the manufacturing line for the
product. We may not always be able to satisfy the qualifications. Delays in
qualification can cause a customer to discontinue use of the product and result
in a significant loss of revenue.

BECAUSE INTEGRATED CIRCUIT AND OPTOELECTRONIC COMPONENT AVERAGE SELLING PRICES
IN PARTICULAR PRODUCT AREAS ARE DECLINING AND SOME OF OUR OLDER PRODUCTS ARE
BECOMING OBSOLETE, OUR RESULTS OF OPERATIONS MAY BE ADVERSELY AFFECTED.

     We have in the past, and will in the future, experience declines in the
average selling prices for some of our integrated circuits and optoelectronic
components. For our products, the declines are due to, among other things,
downturns in the semiconductor industry, increased competition, lower costs of
producing products and greater unit volumes. In addition, because our industry
is characterized by rapid technological change and short product life cycles, in
any given year we may have a substantial amount of revenue from products that
are becoming obsolete. We may experience substantial decreases in sales of these
products in subsequent years.

     If we do not offset these decreases by increases in our sales of other
products, including new products, that can be sold at higher prices, our revenue
will decline, which will have a material adverse effect on our results of
operations.

WE CONDUCT A SIGNIFICANT AMOUNT OF OUR SALES ACTIVITY AND MANUFACTURING EFFORTS
OUTSIDE THE UNITED STATES, WHICH SUBJECTS US TO ADDITIONAL BUSINESS RISKS AND
MAY ADVERSELY AFFECT OUR RESULTS OF OPERATIONS DUE TO INCREASED COSTS.

     In fiscal 2001, we derived 55% of our revenue from sales of our products
shipped to locations outside the United States. We also manufacture a
significant portion of our products outside the United States and are dependent
on international suppliers for many of our parts. We intend to continue to
pursue growth opportunities in both sales and manufacturing internationally.
International operations are subject to a number of risks and potential costs,
which could adversely affect our revenue and results of operations, including:

     - our new brand will not be locally recognized, which will cause us to
       spend significant amounts of time and money to build a brand identity;

     - unexpected changes in regulatory requirements;

     - inadequate protection of intellectual property in some countries outside
       of the United States;

     - currency exchange rate fluctuations; and

     - political and economic instability.

                                        42
<PAGE>

WE ARE SUBJECT TO ENVIRONMENTAL, HEALTH AND SAFETY LAWS, WHICH COULD INCREASE
OUR COSTS AND RESTRICT OUR OPERATIONS IN THE FUTURE.

     We are subject to a variety of laws relating to the use, disposal, clean-up
of, and human exposure to, hazardous chemicals. Any failure by us to comply with
present and future environmental, health and safety requirements could subject
us to future liabilities or the suspension of production. In addition,
compliance with these or future laws could restrict our ability to expand our
facilities or require us to acquire costly pollution control equipment, incur
other significant expenses or modify our manufacturing processes. In the event
of the discovery of additional contaminants or the imposition of additional
cleanup obligations at these or other sites, we could be adversely affected.

BECAUSE MANY OF OUR CURRENT AND PLANNED PRODUCTS ARE HIGHLY COMPLEX, THEY MAY
CONTAIN DEFECTS OR ERRORS THAT ARE DETECTED ONLY AFTER DEPLOYMENT IN COMMERCIAL
COMMUNICATIONS NETWORKS AND IF THIS OCCURS, THEN IT COULD HARM OUR REPUTATION
AND RESULT IN INCREASED EXPENSE.

     Our products are highly complex and may contain undetected defects, errors
or failures. These products can only be fully tested when deployed in commercial
communications networks and other equipment. Consequently, our customers may
discover errors after the products have been deployed. The occurrence of any
defects, errors or failures could result in:

     - cancellation of orders;

     - product returns;

     - diversion of our resources;

     - legal actions by our customers or our customers' end-users;

     - increased insurance costs; and

     - other losses to us or to our customers or end users.

     Any of these occurrences could also result in the loss of or delay in
market acceptance of our products and loss of sales, which would harm our
business and adversely affect our revenue and results of operations. We have
from time to time experienced defects and expect to experience defects in the
future. Because the trend in our industry is moving toward even more complex
products in the future, this risk will intensify over time.

THE COMMUNICATIONS COMPONENT INDUSTRY IS INTENSELY COMPETITIVE, AND OUR FAILURE
TO COMPETE EFFECTIVELY COULD HURT OUR REVENUE.

     The market segments for optoelectronic components and integrated circuits
are intensely competitive and subject to rapid and disruptive technological
change. We expect the intensity of competition to continue to increase in the
future as existing competitors enhance and expand their product offerings and as
new participants enter the market. Increased competition may result in price
reductions, reduced gross margins and loss of market share. We cannot assure you
that we will be able to compete successfully against existing or future
competitors, which may hurt our revenue.

WE MAY BE SUBJECT TO INTELLECTUAL PROPERTY LITIGATION AND INFRINGEMENT CLAIMS,
WHICH COULD CAUSE US TO INCUR SIGNIFICANT EXPENSES OR PREVENT US FROM SELLING
OUR PRODUCTS. IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, OUR
BUSINESSES AND PROSPECTS MAY BE HARMED.

     Like other companies in the semiconductor industry, we experience frequent
litigation regarding patent and other intellectual property rights. From time to
time, we receive notices from third parties of potential infringement and
receive claims of potential infringement when we attempt to license our
intellectual property to others. Defending these claims could be costly and time
consuming and would divert the attention of management and key personnel from
other business issues. The complexity of the technology involved and the
uncertainty of intellectual property litigation increase these risks. Claims of
intellectual property infringement also might require us to enter into costly
royalty or license agreements. However, we may be unable to obtain royalty or
license agreements on terms acceptable to us or at all. In addition, third
parties may attempt to

                                        43
<PAGE>

appropriate the confidential information and proprietary technologies and
processes used in our business, which we may be unable to prevent and would harm
our businesses and prospects.

IF WE CANNOT MAINTAIN OUR STRATEGIC RELATIONSHIPS OR IF OUR STRATEGIC
RELATIONSHIPS FAIL TO MEET THEIR GOALS OF DEVELOPING TECHNOLOGIES OR PROCESSES,
WE WILL LOSE OUR INVESTMENT AND MAY FAIL TO KEEP PACE WITH THE RAPID
TECHNOLOGICAL DEVELOPMENTS IN OUR INDUSTRY.

     In the past, we have entered into strategic relationships to develop
technologies and manufacturing processes. If any of our strategic relationships
do not accomplish our intended goals or do not develop the technology or
processes sought, we will not realize a return on our investment and our
profitability may decline.

WE MAY NOT HAVE FINANCING FOR FUTURE STRATEGIC INITIATIVES, WHICH MAY PREVENT US
FROM ADDRESSING GAPS IN OUR PRODUCT OFFERINGS, IMPROVING OUR TECHNOLOGY OR
INCREASING OUR MANUFACTURING CAPACITY.

     If we are unable to incur additional debt or issue equity for future
strategic initiatives, we may fail to address gaps in our product offerings,
improve our technology or increase our manufacturing capacity. We cannot assure
you that such financing will be available to us on acceptable terms or at all.
Also, in connection with our spin off from Lucent, we are significantly
restricted in our ability to issue stock in order to raise capital.

BECAUSE OUR QUARTERLY REVENUE AND OPERATING RESULTS ARE LIKELY TO VARY
SIGNIFICANTLY IN FUTURE PERIODS DUE TO THE NATURE OF OUR BUSINESS, OUR STOCK
PRICE MAY DECLINE.

     Our quarterly revenue and income (loss) from operations have varied and are
likely to continue to fluctuate significantly from quarter to quarter because of
the nature of our revenue and planned product introductions. For example,
because of our lengthy sales and design processes, the effects of failing to be
selected by a customer to provide a product may result in significantly lower
revenue later, as compared to prior periods with more revenue from earlier
design wins. We have experienced fluctuations in quarterly revenue for this
reason in the past. In addition, sales of our products for specific customer
projects often begin and end abruptly, so revenue may increase rapidly and later
decrease just as quickly. The relative timing of the beginning and end of such
sales can make our revenues less predictable.

RISKS RELATED TO OUR STOCK

     Our stockholders face risks related to our separation from Lucent, our
limited history as a stand-alone company and conditions in our business,
including the following:

     - Because our Class A common stock has a limited trading history and our
       stock may be considered a technology stock, the market price and trading
       volume of our Class A common stock may be volatile.

     - Because our quarterly revenue and operating results are likely to vary
       significantly in future periods, our stock price may decline.

     - Because of differences in voting power and liquidity between the Class A
       common stock and the Class B common stock, the market price of the Class
       A common stock may be less than the market price of the Class B common
       stock following Lucent's distribution of the Class B common stock if
       Lucent completes that distribution.

     - A number of our shares are or will be eligible for future sale or
       distribution, including as a result of our spin-off by Lucent, which may
       cause our stock price to decline.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

RISK MANAGEMENT

     We are exposed to market risk from changes in foreign currency exchange
rates, interest rates and equity prices that could impact our results of
operations and financial position. We manage our exposure to these market risks
through our regular operating and financing activities and, when deemed
appropriate, through the use of derivative financial instruments. We use
derivative financial instruments as risk management tools and not for
speculative purposes. In addition, derivative financial instruments are entered
into with a diversified

                                        44
<PAGE>

group of major financial institutions in order to manage our exposure to
nonperformance on such instruments. Our risk management objective is to minimize
the effects of volatility on our cash flows by identifying the recognized assets
and liabilities or forecasted transactions exposed to these risks and
appropriately hedging the risks.

     We use foreign currency forward contracts, and may from time to time use
foreign currency options, to manage the volatility of non-functional currency
cash flows resulting from changes in exchange rates. Foreign currency exchange
contracts are designated for recorded, firmly committed or anticipated purchases
and sales. The use of these derivative financial instruments allows us to reduce
our overall exposure to exchange rate movements, since the gains and losses on
these contracts substantially offset losses and gains on the assets, liabilities
and transactions being hedged. As of September 30, 2001, our primary net foreign
currency market exposures included Singapore dollars and British Pounds
Sterling.

     The fair value of foreign currency exchange contracts is subject to changes
in foreign currency exchange rates. For the purpose of assessing specific risks,
we use a sensitivity analysis to determine the effects that market risk
exposures may have on the fair value of our financial instruments and results of
operations. The financial instruments included in our sensitivity analysis are
foreign currency forward contracts. These contracts generally have a duration of
three to six months and are primarily used to hedge firmly committed and
anticipated transactions. The sensitivity analysis excludes the values of
foreign currency denominated receivables and payables because of their short
maturities. To perform the sensitivity analysis, we assess the risk of loss in
fair values from the effect of a hypothetical 10% change in foreign currency
exchange spot rates assuming no change in interest rates. For contracts
outstanding as of September 30, 2001 and 2000, a 10% appreciation in foreign
currency exchange rates against the U.S. dollar from the prevailing market rates
would have increased our pre-tax earnings by approximately $2 million and $12
million, respectively. Conversely, a 10% depreciation in these exchange rates
from the prevailing market rates would have decreased our pre-tax earnings by
approximately $2 million and $12 million, respectively. Consistent with the
nature of the economic hedge of foreign currency exchange contracts, these gains
or losses would be offset by corresponding decreases or increases, respectively,
of the underlying instrument or transaction being hedged.

     The model assumes a parallel shift in all foreign currency exchange spot
rates. Exchange rates, however, rarely move in the same direction. The
assumption that all exchange rates change in a parallel manner does not
necessarily represent the actual changes in fair value we would incur under
normal market conditions because all variables other than the specific market
risk are held constant.

     Effective October 1, 2000, we adopted Statement 133 and its corresponding
amendments under Statement 138. The adoption of Statement 133 resulted in a
cumulative effect of an increase in our net loss of $4 million, net of a tax
benefit of $2 million in fiscal 2001. The increase in our net loss is primarily
due to derivatives not designated as hedging instruments. For the fiscal year
ended September 30, 2001, the change in fair market value of derivative
instruments was recorded in other income-net and was not material.

     While we hedge certain foreign currency transactions, a decline in value of
non-U.S. dollar currencies may adversely affect our ability to contract for
product sales in U.S. dollars because our products may become more expensive to
purchase in U.S. dollars for local customers doing business in the countries of
the affected currencies.

     As of September 30, 2001, we had $2,500 million of short-term variable rate
debt outstanding. To manage the cash flow risk associated with this debt, we
may, from time to time, enter into interest rate swap agreements. There were no
interest rate swap agreements in effect during fiscal 2001 or fiscal 2000. As of
September 30, 2001, a variation of 1% in the interest rate charged on the
short-term debt would result in a change of approximately $25 million in annual
interest expense. Following the repayment of $1,000 million of loans under the
credit facility on October 4, 2001, a variation of 1% in the interest rate
charged would result in a change of approximately $15 million in annual interest
expense.

     Our investment portfolio consists of equity investments accounted for under
the cost and equity methods as well as an investment in a publicly held company
that is classified as available-for-sale. At September 30, 2001 the fair value
of this available for sale security totaled $41 million. We do not hedge equity
price risk. As of September 30, 2001, a 20% adverse change in equity prices
would result in an approximate $8 million decrease in the fair value of our
available-for-sale security.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Agere Systems Inc.:

     In our opinion, the consolidated and combined financial statements listed
in the accompanying index present fairly, in all material respects, the
financial position of Agere Systems Inc. and its subsidiaries at September 30,
2001 and 2000, and the results of their operations and their cash flows for each
of the three years in the period ended September 30, 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
accompanying index presents fairly, in all material respects, the information
set forth therein when read in conjunction with the related consolidated and
combined financial statements. These financial statements and the financial
statement schedule are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements and the
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.

     Prior to its separation from Lucent Technologies Inc. ("Lucent") on
February 1, 2001 the Company was comprised of businesses which were integrated
with the businesses of Lucent; consequently, as indicated in Note 1, the
financial statement amounts prior to this date have been derived from the
consolidated financial statements and accounting records of Lucent, and reflect
significant assumptions and allocations. Moreover, as indicated in Note 1, the
Company relied on Lucent and its other businesses for administrative,
management, research and other services. Accordingly, these financial statements
do not necessarily reflect the financial position, results of operations, and
cash flows of the Company had it been a stand-alone company.

     As discussed in Note 4 to the consolidated and combined financial
statements, effective October 1, 2000, the Company changed its accounting method
for derivative instruments and hedging activity. As discussed in Note 2,
effective October 1, 1999, the Company changed its accounting method for
computer software developed or obtained for internal use. As discussed in Note
16, effective October 1, 1998, the Company changed its method for calculating
annual pension and postretirement benefit costs.

            NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

1.  BACKGROUND AND BASIS OF PRESENTATION

  BACKGROUND

     On July 20, 2000, Lucent Technologies Inc. ("Lucent") announced its
intention to spin off its integrated circuits and optoelectronic components
businesses (collectively, the "Company's Businesses") that now comprise Agere
Systems Inc. (the "Company" or "Agere"). At that time, Lucent announced it
intended to distribute all shares of the Company's common stock it then owned to
its stockholders in a tax free distribution (the "Distribution") by the end of
Lucent's then current fiscal year, September 30, 2001, following the initial
public offering ("IPO") of the Company's Class A common stock, which was
completed in April 2001.

     On August 1, 2000, the Company was incorporated in Delaware as a wholly
owned subsidiary of Lucent. On this date, 1,000 shares of the Company's common
stock, par value $0.01 per share, were issued, authorized and outstanding.
Effective February 1, 2001, Lucent transferred to the Company substantially all
of the assets and liabilities of the Company's Businesses (the "Separation")
except for short-term debt and related fees which were transferred at the IPO
closing date, and pension and postretirement plan assets and liabilities which
will be transferred at a later date.

     On March 14, 2001, the Company amended its certificate of incorporation to
authorize shares of Class A and Class B common stock and changed and
reclassified its 1,000 outstanding shares of common stock into 1,035,100,000
shares of Class B common stock (the "Recapitalization"). The ownership rights of
Class A and Class B common stockholders are the same except that each share of
Class B common stock has four votes for the election and removal of directors
while each share of Class A common stock has one vote for such matters. All
Company share and per share data has been retroactively adjusted to reflect the
Recapitalization as if it had occurred at the beginning of the earliest period
presented. On April 2, 2001, the Company issued 600,000,000 shares of Class A
common stock in the IPO for $6 per share less underwriting discounts and
commissions of $.23 per share. On April 4, 2001, Lucent converted 90,000,000
shares of Class B common stock into Class A common stock and exchanged those
shares for outstanding Lucent debt with Morgan Stanley pursuant to the
overallotment option granted in connection with the IPO. After completion of the
IPO, inclusive of the overallotment option, Lucent owned approximately 58% of
the aggregate number of outstanding shares of Class A and B common stock. Also,
on April 2, 2001, the Company assumed from Lucent $2,500 of short-term debt. On
May 1, 2001, Lucent elected to convert 37,000,000 of its shares in the Company
from Class B common stock to Class A common stock.

     Agere is currently a majority-owned subsidiary of Lucent. On August 16,
2001, Lucent announced that it had entered into amendments with the lenders
under its credit facilities that impose a number of conditions that Lucent must
satisfy in order to spin off Agere. Lucent has stated that it remains committed
to completing the process of separating Agere from Lucent, and that it intends
to move forward with the distribution of the Agere stock it holds in a tax-free
distribution. Because Lucent must meet a number of conditions before it can
complete the spin off and because Lucent alone will make the decision about
whether to complete the spin off, even if the conditions were met, we can not
assure you that Lucent will complete the spin off by a particular date or at
all.

     The Company adopted a rights agreement prior to the completion of the IPO.
The delivery of a share of the Company's common stock currently constitutes the
delivery of a preferred stock purchase right associated with such share. These
rights may have anti-takeover effects in that the existence of the rights may
deter a potential acquiror from making a takeover proposal or a tender offer.

  BASIS OF PRESENTATION

     The consolidated and combined financial statements include amounts prior to
February 1, 2001 that have been derived from the consolidated financial
statements and accounting records of Lucent using the historical results of
operations and historical basis of the assets and liabilities of the Company's
Businesses. Manage-

                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

ment believes the assumptions underlying the consolidated and combined financial
statements are reasonable. However, the consolidated and combined financial
statements included herein may not necessarily reflect the Company's results of
operations, financial position and cash flows in the future or what its results
of operations, financial position and cash flows would have been had the Company
been a stand-alone company during the periods presented. Because a direct
ownership relationship did not exist among all the various units comprising the
Company, Lucent's net investment in the Company is shown in lieu of
stockholders' equity in the combined financial statements prior to the
Separation. The Company began accumulating retained earnings on February 1,
2001, the date on which Lucent began transferring to the Company the assets and
liabilities of the Company's Businesses. The formation of the Company and the
transfers of assets and liabilities from Lucent have been accounted for as a
reorganization of entities under common control in a manner similar to a pooling
of interests.

     The consolidated and combined financial statements include allocations of
certain Lucent expenses, assets and liabilities, including the items described
below.

  General Corporate Expenses

     Lucent allocated general corporate expenses based on revenue prior to
February 1, 2001. These allocations were reflected in the selling, general and
administrative, costs and research and development line items in the
consolidated and combined statements of operations. The general corporate
expense allocations were primarily for cash management, legal, accounting, tax,
insurance, public relations, advertising, human resources and data services.
These allocations amounted to $60, $178 and $194 for fiscal 2001, 2000 and 1999,
respectively. Management believes the costs of these services charged to the
Company are a reasonable representation of the costs that would have been
incurred if the Company had performed these functions as a stand-alone company.
Since the Separation, the Company has performed these functions using its own
resources or through purchased services. The Company and Lucent entered into
agreements for Lucent to provide certain general corporate services on a
transition basis. See Note 19 "Transactions with Lucent."

  Basic Research

     Prior to February 1, 2001, research and development expenses included an
allocation from Lucent to fund a portion of the costs of basic research
conducted by Lucent's Bell Laboratories. This allocation was based on the number
of individuals conducting basic research who were transferred from Lucent's Bell
Laboratories to the Company as part of the Separation. This allocation amounted
to $23, $66 and $64 for fiscal 2001, 2000 and 1999, respectively. Management
believes the costs of this research charged to the Company are a reasonable
representation of the costs that would have been incurred if the Company had
performed this research as a stand-alone company. The expenses for basic
research currently conducted by the Company are included with all other research
and development expenses in the consolidated statements of operations.

  Interest Expense

     Prior to the Separation, Lucent provided financing to the Company and
incurred debt at the parent level. The combined balance sheets, prior to the
IPO, do not include debt other than capitalized lease obligations. As a result
of the Separation, there was no interest expense allocated to the Company from
Lucent after January 31, 2001. The consolidated and combined statements of
operations, however, include an allocation of interest expense totaling $32, $52
and $38, for fiscal 2001, 2000 and 1999, respectively. This allocation was based
on the ratio of the Company's net assets, excluding debt, to Lucent's total net
assets, excluding debt. The Company's interest expense as a stand-alone company
is higher than that reflected in the combined statements of operations,
primarily due to the $2,500 credit facility assumed from Lucent following the
IPO. Interest expense for all periods presented also includes interest expense
related to the Company's capitalized lease obligation.

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

  Pension and Postretirement Costs

     The documents relating to the Separation provide that, until the
Distribution, the Company's United States ("U.S.") employees will be
participants in Lucent's pension plans. At the Distribution, the Company will
become responsible for pension benefits for the active U.S. employees of the
Company, as well as U.S. employees who retire or terminate after the IPO. Lucent
will transfer to the Company the pension and postretirement assets and
liabilities related to these employees at the Distribution. Obligations related
to retired and terminated vested U.S. employees prior to the IPO will remain the
responsibility of Lucent. Lucent has managed its U.S. pension and postretirement
benefit plans on a consolidated basis and separate Company information is not
readily available. The consolidated and combined statements of operations
include, however, an allocation of the costs (benefits) of the U.S. employee
pension and postretirement plans. These costs (benefits) were allocated based on
the Company's U.S. active employee population for each of the years presented.
In relation to the Lucent plans, the Company recorded pension (benefit) expense
of $(2), $27 and $38, for fiscal 2001, 2000 and 1999, respectively, and
postretirement expense of $10, $15 and $17, for fiscal 2001, 2000 and 1999,
respectively. The Company is responsible for the pension and postretirement
benefits of its non-U.S. employees. The liabilities of the various
country-specific plans for these employees are reflected in the consolidated and
combined financial statements and were not material for the periods presented.
There are estimated prepaid pension assets of $122 and postretirement
liabilities of $86 as of September 30, 2001 associated with various existing
Lucent pension and other employee benefit plans related to the Company's
employees. These assets and liabilities will not be reflected in the Company's
financial statements until the plan assets and liabilities are transferred. The
amounts transferred to the Company for prepaid pension assets and postretirement
liabilities could be materially different than these amounts at the
Distribution.

  Income Taxes

     The Company's income taxes have been calculated on a separate tax return
basis prior to the IPO. This reflects Lucent's tax strategies, and is not
necessarily reflective of the tax strategies that the Company would have
followed or will follow as a stand-alone company.

  Cash and Receivables

     Prior to the Separation, cash deposits from the Company's Businesses were
transferred to Lucent on a regular basis and were netted against the owner's net
investment account as Lucent used a centralized approach to cash management and
the financing of its operations. As a result, none of Lucent's cash, cash
equivalents or debt was allocated to the Company in the combined financial
statements. The receivable from Lucent reflected in the combined balance sheet
included both accounts receivable related to non-U.S. sales to Lucent as well as
an amount of receivables for sales to Lucent in the U.S. that were historically
settled through owner's net investment. In order to better reflect the historic
trends in working capital resulting from the sales to Lucent in the U.S. and
provide a more meaningful basis of comparison in future periods, the Company had
carved out of the owner's net investment account at September 30, 2000 an amount
of receivables related to the sales to Lucent in the U.S. calculated using the
Company's days sales outstanding for third party receivables. At September 30,
2000, such amounts included in receivables due from Lucent were $90. Changes in
invested equity represent any funding required from Lucent for working capital,
acquisition or capital expenditure requirements after giving effect to the
Company's transfers of cash to or from Lucent.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  PRINCIPLES OF COMBINATION AND CONSOLIDATION

     Prior to the Separation, the combined financial statements included certain
majority owned subsidiaries and assets and liabilities of the Company's
Businesses not owned by the Company that were transferred to the Company from
Lucent on February 1, 2001. Following the Separation, the Company's consolidated
financial statements include the accounts of majority owned subsidiaries which
it controls and assets and liabilities of the Company. Investments in which the
Company exercises significant influence, but which it does not control are
accounted for under the equity method of accounting. Investments in which the
Company does not exercise significant influence are recorded at cost. All
material inter-company transactions and balances between and among the Company's
Businesses, subsidiaries and investees accounted for under the equity method of
accounting have been eliminated.

  USE OF ESTIMATES

     The preparation of financial statements and related disclosures in
conformity with accounting principles generally accepted in the U.S. requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the financial statements, and revenue and expenses during the period
reported. Estimates and assumptions are reviewed periodically and the effects of
revisions are reflected in the period that they are determined to be necessary.
These estimates include an allocation of costs by Lucent, assessing the
collectability of accounts receivable, the use and recoverability of inventory,
the realization of deferred tax assets, employee benefits, restructuring
reserves, useful lives for depreciation and amortization periods of tangible and
intangible assets, and long-lived asset impairments among others. The markets
for the Company's products are characterized by intense competition, rapid
technological development, evolving standards, short product life cycles and
price erosion, all of which could impact the future realizability of the
Company's assets. Actual results could differ from those estimates.

  FOREIGN CURRENCY TRANSLATION

     Balance sheet accounts of the Company's foreign operations for which the
local currency is the functional currency are translated into U.S. dollars at
period-end exchange rates, while income, expenses and cash flows are translated
at average exchange rates during the period. Translation gains or losses related
to net assets of such operations are shown as a component of accumulated other
comprehensive income (loss) in stockholders' equity/invested equity. Gains and
losses resulting from foreign currency transactions, which are transactions
denominated in a currency other than the entity's functional currency, are
included in the consolidated and combined statements of operations.

  REVENUE RECOGNITION

     Revenue is derived from sales of products in the integrated circuits and
optoelectronic segments and from intellectual property licensing. Revenue is
recognized when contractual obligations have been satisfied, title and risk of
loss have been transferred to the customer and collection of the resulting
receivable is reasonably assured. The Company recognizes revenue from product
sales to distributors when all obligations have been satisfied. The Company's
distributor arrangements generally provide for limited product returns and price
protection. A provision for estimated sales returns and other allowances is
recognized as a reduction of revenue at the time of revenue recognition based
upon historical experience. The Company has not historically entered into
long-term contracts or service agreements. Revenue from intellectual property
licensing revenue is recognized over the license term. Estimated sales
allowances are provided as a reduction of revenue at the time of revenue
recognition.

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

     In December 1999, the staff of the Securities and Exchange Commission
issued Staff Accounting Bulletin 101, "Revenue Recognition in Financial
Statements" ("SAB 101"). SAB 101 provides guidance on the recognition,
presentation and disclosure of revenue in financial statements. The Company
adopted SAB 101 in the fourth quarter of fiscal 2001. The impact of adoption was
not material to its consolidated financial position or results of operations.

  RESEARCH AND DEVELOPMENT COSTS

     Research and development costs are charged to expense as incurred.

  CASH AND CASH EQUIVALENTS

     The Company considers all liquid investments with original maturities of
ninety days or less to be cash equivalents. Cash is reflected net of outstanding
checks.

  INVENTORIES

     Inventories are stated at the lower of cost, determined on a first-in,
first-out basis, or market.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are stated at cost less accumulated
depreciation. Depreciation and amortization is determined using a combination of
either accelerated or straight-line methods over the estimated useful lives of
the various asset classes.

     Estimated useful lives range from three to five years for machinery,
electronic and other equipment, and up to forty years for buildings. Major
renewals and improvements are capitalized and minor replacements, maintenance,
and repairs are charged to current operations as incurred. Upon retirement or
disposal of assets, the cost and related accumulated depreciation are removed
from the consolidated and combined balance sheets and any gain or loss is
reflected in the consolidated and combined statements of operations.

  INTERNAL USE SOFTWARE

     The Company adopted Statement of Position ("SOP") 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use" on October 1,
1999. Certain costs of computer software developed or obtained for internal use,
that were previously expensed as incurred, are capitalized and amortized on a
straight-line basis over three years. Costs for general and administrative,
overhead, maintenance and training, as well as the cost of software that does
not add functionality to the existing system, are expensed as incurred.

  GOODWILL AND OTHER ACQUIRED INTANGIBLES

     Goodwill and other acquired intangibles are amortized on a straight-line
basis over the periods benefited, principally in the range of four to nine
years. Goodwill is the excess of the purchase price over the fair value of
identifiable net assets acquired in business combinations accounted for as
purchases.

  IMPAIRMENT OF LONG-LIVED ASSETS

     Long-lived assets, including goodwill and other acquired intangibles, are
reviewed for impairment whenever events such as a significant industry downturn,
product discontinuance, plant closures, product dispositions, technological
obsolescence or other changes in circumstances indicate that the carrying amount
may not be recoverable. When such events occur, the Company compares the
carrying amount of the assets to undiscounted expected future cash flows. If
this comparison indicates that there is an impairment, the amount of the
impairment is typically calculated using discounted expected future cash flows.
                                        56
<PAGE>
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

  FINANCIAL INSTRUMENTS

     The Company uses various financial instruments, including foreign currency
exchange forward contracts, to manage and reduce risk to the Company by
generating cash flows which offset the cash flows of certain transactions in
foreign currencies or underlying financial instruments in relation to their
amount and timing. The Company's derivative financial instruments are for
purposes other than trading. The Company's non-derivative financial instruments
include letters of credit.

  INVESTMENTS

     Investments in marketable securities that are available for sale are
recorded at fair value. Unrealized gains and losses related to these securities
are excluded from earnings and are included as a separate component of
comprehensive income (loss) until such gains or losses are realized.

     Minority equity investments in non-publicly traded companies are generally
carried at cost. The Company monitors these investments for impairment and makes
appropriate reductions in carrying values when necessary.

  INCOME TAXES

     Historically, certain of the Company's operations have been included in
Lucent's consolidated income tax returns. Income tax expense in the Company's
consolidated and combined statements of operations has been calculated on a
separate tax return basis prior to the IPO. The asset and liability approach is
used to recognize deferred tax assets and liabilities for the expected future
tax consequences of temporary differences between the carrying amounts and the
tax bases of assets and liabilities. A valuation allowance is established, as
needed, to reduce net deferred tax assets to the amount for which recovery is
probable.

  EARNINGS (LOSS) PER SHARE

     Basic and diluted earnings (loss) per common share for all periods prior to
the IPO is calculated by dividing net income (loss) by 1,035,000,000, which is
the number of shares issued to Lucent on August 1, 2000 as retroactively
adjusted for the Recapitalization. For periods following the IPO, basic earnings
(loss) per common share is calculated by dividing net income (loss) by the
weighted average number of common shares outstanding during the period and
diluted earnings (loss) per common share is calculated by dividing net income
(loss) by the sum of the weighted average number of common shares outstanding,
plus all additional common shares that would have been outstanding if
potentially dilutive securities or common stock equivalents had been issued.
Because of the Company's net loss, the effect of dilutive securities for fiscal
2001 was not considered.

  OTHER COMPREHENSIVE INCOME (LOSS)

     Total comprehensive income (loss) includes, in addition to net income
(loss), unrealized gains and losses excluded from the consolidated and combined
statements of operations that are recorded directly into a separate section of
stockholders' equity/invested equity on the consolidated and combined balance
sheets. These unrealized gains and losses are referred to as other comprehensive
income (loss). The Company's accumulated other comprehensive income (loss) shown
on the consolidated and combined balance sheets consists of foreign currency
translation adjustments which are not adjusted for income taxes because they
relate to indefinite investments in non-U.S. subsidiaries, unrealized investment
holding gains and losses which also are not adjusted for income taxes and
unrealized losses on cash flow hedges which also are not adjusted for income
taxes.

3.  ACQUISITIONS

     The following table presents information about certain acquisitions in
fiscal 2000 and 1999. No significant acquisitions occurred during fiscal 2001.
All the acquisitions were accounted for under the purchase method of accounting,
and the acquired technology valuation included existing technology, purchased
in-process research and development ("IPRD") and other intangibles. IPRD charges
were recorded in the quarter in which the transaction was completed. The
consolidated and combined financial statements include the results of operations
and the estimated fair value of assets and liabilities assumed from the
respective dates of acquisitions. The acquired entities are 100% owned.

(1) Herrmann Technology, Inc. was a developer and manufacturer of passive
    optical filters that could be used in conjunction with active optoelectronic
    components. The purchase price was paid in Lucent common stock and options.

(2) Ortel Corporation was a developer and manufacturer of optoelectronic
    components used in fiber optic systems for cable television and data
    communications networks. The purchase price was paid in Lucent common stock
    and options.

(3) Agere, Inc. was a developer of network processor integrated circuits. The
    purchase price was paid in Lucent common stock and options.

(4) VTC Inc. was a supplier of integrated circuits to computer hard disk drive
    manufacturers. The purchase price was paid in cash.

(5) Enable Semiconductor, Inc. was a developer of integrated circuits for local
    area network equipment. The purchase price was paid in cash.

(6) Sybarus Technologies, ULC was a developer of integrated circuits for
    communications networks. The purchase price was paid in cash.

     In connection with the acquisition of Herrmann, certain former stockholders
of Herrmann were entitled to receive up to a total of 677,019 additional shares
of Lucent common stock. Of that amount, 150,000 shares are based on retention,
which is recorded as compensation expense over the two-year period following the
acquisition and 527,019 shares are based on the achievement of specified
milestones which require the production of two products at improved
manufacturing yields. As of September 30, 2001, 200,000 of the shares related to
the achievement of milestones have been issued, resulting in additional
goodwill. The remaining shares based on milestones, if distributed, will also be
treated as additional goodwill.

     In connection with the acquisition of substantially all the assets of VTC,
stockholders of VTC are entitled to receive additional cash consideration of up
to $50 contingent on the delivery of product at specified manufacturing yields
and the transfer and qualification of process technology to the Company's
manufacturing facilities. As of September 30, 2001, $30 of the additional cash
consideration has been paid, resulting in additional goodwill. Any future cash
consideration, if paid, will also be recorded as additional goodwill.

     Included in the purchase price for the above acquisitions was IPRD, which
was a non-cash charge to earnings for technology that had not reached
technological feasibility and had no future alternative use. The remaining
purchase price was allocated to tangible assets and intangible assets, including
goodwill and other acquired intangibles, less liabilities assumed.

     The value allocated to IPRD was determined utilizing an income approach
that included an excess earnings analysis reflecting the appropriate cost of
capital for the investment. Estimates of future cash flows related to the IPRD
were made for each project based on Lucent's estimates of revenue, operating
expenses and income taxes from the project. These estimates were consistent with
historical pricing, gross margins and expense levels for similar products.

     Revenue was estimated based on relevant market size and growth factors,
expected industry trends, individual product sales cycles and the estimated life
of each product's underlying technology. Estimated operating expenses, income
taxes, and charges for the use of contributory assets for each project were
deducted from estimated revenue to determine estimated after-tax cash flows for
each project. Estimated operating expenses include costs, selling, general and
administrative expenses and research and development expenses. The research and
development expenses include estimated costs to maintain the products once they
have been introduced into the market and generate revenue and costs to complete
the IPRD.

     The discount rates utilized to discount the projected cash flows for each
project were based on consideration of Lucent's weighted average cost of
capital, as well as other factors including the useful life of each project, the
anticipated profitability of each project, the uncertainty of technology
advances that were known at the time and the stage of completion of each
project.

     Management is primarily responsible for estimating the fair value of the
assets and liabilities acquired, and has conducted due diligence in determining
the fair value. Management has made estimates and assumptions that affect the
reported amounts of assets, liabilities and expenses resulting from such
acquisitions. Actual results could differ from those amounts.

     During fiscal 2001, it was determined that there was an other than
temporary impairment to some of the goodwill and other acquired intangibles
related to the acquisitions of Ortel, Herrmann Technology, Agere, Inc. and
Enable Semiconductor. See Note 7 "Impairment of Goodwill and Other Acquired
Intangibles."

     The following unaudited pro forma statement of income data for fiscal 2000
and 1999 give effect to the acquisition of Ortel as if it occurred on October 1,
1999 and 1998, respectively.

4.  ACCOUNTING CHANGES

     Effective October 1, 2000, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"), and its corresponding amendments under
SFAS No. 138. SFAS 133 requires the Company to measure all derivatives,
including certain derivatives embedded in other contracts, at fair value and to
recognize them in

                                        59
<PAGE>
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

the balance sheet as an asset or liability, depending on the Company's rights or
obligations under the applicable derivative contract. For derivatives designated
as fair value hedges, the changes in the fair value of both the derivative
instrument and the hedged item are recorded in earnings. For derivatives
designated as cash flow hedges, the effective portions of changes in fair value
of the derivative are reported in other comprehensive income and are
subsequently reclassified into earnings when the hedged item affects earnings.
Changes in fair value of derivative instruments not designated as hedging
instruments and ineffective portions of hedges are recognized in earnings in the
current period. The adoption of SFAS 133 as of October 1, 2000, resulted in a
cumulative after-tax increase in net loss of $4 (net of a tax benefit of $2).
The increase in net loss is primarily due to derivatives not designated as
hedging instruments. For fiscal 2001, the change in fair market value of
derivative instruments was recorded in other income-net and was not material.

5.  RECENT PRONOUNCEMENTS

  SFAS 142

     In July 2001, the Financial Accounting Standards Board issued SFAS No. 142,
"Goodwill and Other Intangible Assets" ("SFAS 142"). SFAS 142 provides guidance
on the financial accounting and reporting for acquired goodwill and other
intangible assets. Under SFAS 142, goodwill and indefinite lived intangible
assets will no longer be amortized but will be reviewed for impairment at least
annually and subject to new impairment tests. Intangible assets with finite
lives will continue to be amortized over their useful lives but will no longer
be limited to a maximum life of forty years. SFAS 142 is effective for Agere in
fiscal year 2003, although earlier application is permitted. The Company plans
to adopt SFAS 142 effective October 1, 2002 and is currently evaluating the
potential effects of implementing this standard on its financial condition and
results of operations.

  SFAS 143

     Also in July 2001, the Financial Accounting Standards Board issued SFAS No.
143, "Accounting for Asset Retirement Obligations" ("SFAS 143"). SFAS 143
addresses financial accounting and reporting for legal obligations associated
with the retirement of tangible long-lived assets and their associated
retirement costs. In accordance with SFAS 143, retirement obligations will be
recognized at fair value in the period they are incurred. When the liability is
initially recorded, the cost is capitalized by increasing the asset's carrying
value, which is subsequently depreciated over its useful life. SFAS 143 is
effective for Agere in fiscal year 2003, with earlier application encouraged.
The Company is currently evaluating the potential effects, if any, on its
financial condition and results of operations of adopting SFAS 143, as well as
the timing of its adoption.

  SFAS 144

     In October 2001, the Financial Accounting Standards Board issued SFAS No.
144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS
144"). SFAS 144 primarily addresses financial accounting and reporting for the
impairment or disposal of long-lived assets and also affects certain aspects of
accounting for discontinued operations. SFAS 144 is effective for Agere in
fiscal year 2003, with earlier application encouraged. The Company is currently
evaluating the potential effects, if any, on its financial condition and results
of operations of adopting SFAS 144, as well as the timing of its adoption.

6.  RESTRUCTURING AND SEPARATION EXPENSES AND INVENTORY PROVISION

  RESTRUCTURING EXPENSES

     In fiscal 2001, the Company announced a series of restructuring initiatives
to align the Company with market conditions. These initiatives were focused on
improving gross profit, reducing expenses and streamlining operations. The
Company recorded a restructuring charge of $563 for the year ended September 30,
2001

                                        60
<PAGE>
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

classified within restructuring and separation expenses. These restructuring
initiatives include a worldwide workforce reduction, rationalization of
manufacturing capacity, and other activities.

  Worldwide Workforce Reduction

     The restructuring initiatives announced in fiscal 2001 will result in a
workforce reduction of approximately 6,000 employees across various business
functions, operating units and geographic regions, and includes management and
occupational employees. The Company recorded a restructuring charge of $177 for
fiscal 2001 relating to approximately 5,500 employees, of which approximately
4,300 employees have been taken off-roll as of September 30, 2001, and expects
to record a restructuring charge related to the additional 500 employees by the
end of the first quarter of fiscal 2002. Of the $177 charge, $28 represents
termination benefits to certain U.S. management employees that will be funded
through Lucent's pension assets. Severance costs and other exit costs noted
above were determined in accordance with Emerging Issues Task Force No. 94-3,
"Liability Recognition for Certain Employee Termination Benefits and Other Costs
to Exit an Activity."

  Rationalization of Manufacturing Capacity and Other Charges

     The Company recorded a restructuring charge of $386 in fiscal 2001 relating
to the rationalization of under-utilized manufacturing facilities and other
restructuring-related activities. The Company has discontinued its manufacturing
operations at its chip fabrication plant in Madrid, Spain. The Company is also
rationalizing under-utilized manufacturing capacity at its facilities in
Orlando, Florida, and in Allentown, Breiningsville, and Reading, Pennsylvania.
In addition, the Company is consolidating several satellite-manufacturing sites
as well as leased corporate offices. The restructuring charge for fiscal 2001
includes $37, related to facility closings primarily for lease terminations,
non-cancelable leases and related costs. It also includes an asset impairment
charge of $287 for fiscal 2001 related to property, plant, and equipment
associated with the consolidation of manufacturing and other corporate
facilities. This charge was recognized in accordance with the guidance on
impairment of assets in SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of." The remaining
restructuring charge of $62 for fiscal 2001 relates primarily to contract
terminations.

     A summary of restructuring costs is outlined as follows:

</Table>

     We anticipate that the majority of the remaining cash expenditures relating
to workforce reductions will be paid by the end of the calendar year and the
majority of the contract terminations will be paid by the end of the second
fiscal quarter of 2002. Amounts related to non-cancelable lease obligations due
to the consolidation of facilities will be paid over the respective lease terms
through fiscal 2005. We expect to substantially complete implementation of the
announced restructuring program by December 31, 2001.

<PAGE>
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

  SEPARATION EXPENSES

     The Company incurred costs, fees and expenses relating to the Separation.
These costs, fees and expenses were primarily related to legal separation
matters, designing and constructing the Company's computer infrastructure,
information and data storage systems, marketing expenses relating to building a
company brand identity and implementing treasury, real estate, pension and
records retention management services. In fiscal 2001, the Company incurred $99
of separation expenses included in restructuring and separation expenses.

  INVENTORY PROVISION

     The Company recorded inventory provisions, classified within cost of sales,
of $409 in fiscal 2001 compared to inventory provisions of $29 in fiscal 2000.
The fiscal 2001 amount, which includes purchase order cancellation charges,
reflects significant decrease in forecasted revenue and was calculated in
accordance with the Company's inventory valuation policy, which is based on a
review of forecasted demand compared with existing inventory levels.

7.  IMPAIRMENT OF GOODWILL AND OTHER ACQUIRED INTANGIBLES

     The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances occur that indicate the carrying amount of the assets
may not be fully recoverable. During fiscal 2001, the Company evaluated goodwill
and other acquired intangibles associated with recent acquisitions for
impairment. The assessment was performed in accordance with SFAS 121 as a result
of weakening economic conditions and decreased current and expected future
demand for products in the markets in which the Company operates. Fair value of
the acquired entities was determined using a discounted cash flow model based on
growth rates and margins reflective of lower demand for the Company's products,
as well as anticipated future demand. Discount rates used were based upon the
Company's weighted average cost of capital adjusted for business risks. These
amounts are based on management's best estimate of future results.

     As a result of the assessment, the Company determined that an other than
temporary impairment existed related to the Company's acquisitions of Ortel,
Herrmann Technology, Agere, Inc. and Enable Semiconductor. The Company recorded
a charge to reduce goodwill and other acquired intangibles of $2,762 during
fiscal 2001, consisting of $2,220, $275, $240 and $27 related to Ortel, Herrmann
Technology, Agere, Inc. and Enable Semiconductor, respectively.

  CASH FLOW INFORMATION

     Prior to the Separation, interest and income taxes were paid by Lucent on
behalf of the Company and do not necessarily reflect what the Company would have
paid had it been a stand-alone company. Following the Separation, the Company
began to pay interest and income tax expenses. Interest for fiscal 2001 is
primarily related to the $2,500 credit facility assumed from Lucent in
connection with the IPO and the Company's capitalized lease obligation. The
interest and income tax payments were $84 and $52, respectively, for fiscal
2001.

     Transfers from Lucent include the following non-cash transactions: (1) a
$2,500 decrease to additional paid in capital to reflect the transfer of the
credit facility; Agere did not receive any of the proceeds, (2) a $3,807
increase in owner's net investment, to reflect the Ortel, Herrmann and Agere,
Inc. acquisitions that

decrease in owner's net investment for a change in accounting related to pension
and postretirement benefit costs reflected in fiscal 1999.

     A capital lease obligation of $83 was entered into in fiscal 1999, for the
lease of semiconductor manufacturing equipment.

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

     The Company has not provided for U.S. deferred income taxes or foreign
withholding taxes on $423 undistributed earnings of its non-U.S. subsidiaries as
of September 30, 2001, because these earnings are intended to be reinvested
indefinitely.

10.  AVAILABLE-FOR-SALE SECURITIES

     The Company's investments in marketable securities are classified as
"available-for-sale" in accordance with Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investment in Debt and Equity
Securities." These investments are carried at fair value with any unrealized
gains and losses recorded as a separate component of other comprehensive income
(loss). Fair value is based upon market prices quoted on the last day of the
fiscal year. The fair market value of available-for-sale securities included in
the consolidated and combined balance sheet was $41 as of September 30, 2001 and
the Company had no available-for-sale securities as of September 30, 2000. The
unrealized gain recorded as a separate component of other comprehensive income
(loss) for fiscal 2001 was $30.

11.  INVESTMENT IN SILICON MANUFACTURING PARTNERS

     In December 1997, the Company entered into a joint venture, called Silicon
Manufacturing Partners Pte Ltd. ("SMP"), with Chartered Semiconductor
Manufacturing Ltd.'s ("Chartered Semiconductor"), a leading manufacturing
foundry for integrated circuits, to operate a 54,000 square foot integrated
circuit manufacturing facility in Singapore. The Company owns a 51% equity
interest in this joint venture, and Chartered Semiconductor owns the remaining
49% equity interest. The Company's 51% interest in SMP is accounted for under
the equity method due to Chartered Semiconductor's participatory rights under
the joint venture agreement. Under the joint venture agreement, each partner is
entitled to the margins from sales to customers directed to SMP by that partner,
after deducting their respective share of the overhead costs of SMP.
Accordingly, SMP's net income (loss) is not expected to be shared in the same
ratio as equity ownership. The Company recognized equity earnings (losses) of
$54, $0 and $(24) in fiscal 2001, 2000 and 1999, respectively.

     The following table shows the condensed balance sheets and statements of
operations of SMP:

     Effective January 1, 2001, SMP adopted SFAS 133. During the nine months
ended September 30, 2001, SMP entered into cash flow hedges to manage interest
rate risk due to its floating interest rate debt and recorded an unrealized loss
of $25 from these hedges as a separate component of other comprehensive income

(loss) for the nine months ended September 30, 2001. As a result, the Company
recorded an unrealized loss of $13 in other comprehensive income (loss).

12.  DEBT

     On April 2, 2001, the Company assumed $2,500 of short-term borrowings under
a credit facility with financial institutions from Lucent. In addition, the
Company assumed $54 of prepaid financing fees, which will be amortized over the
life of facility. The facility is comprised of term loans and revolving credit
loans. The Company did not receive any of the proceeds of this short-term debt.
The credit facility is secured by the Company's principal domestic assets other
than the proceeds of the IPO and while Lucent remains a majority stockholder,
real estate. Upon the repayment of $1,500 of the debt, and if the Company has
credit ratings of BBB- or better with a stable outlook from Standard & Poor's
and Baa3 or better with a stable outlook from Moody's Investor Services, the
debt will become uncollateralized. At September 30, 2001, Agere's ratings were
BB- from Standard & Poor's with a stable outlook and Ba3 from Moody's Investor
Services with a stable outlook. Upon the repayment of $1,500, the remaining debt
outstanding under this facility would consist of revolving credit loans. The
credit facility will mature on February 21, 2002, which is 364 days from the
date Lucent initially entered into the facility. The debt is not convertible
into any other securities of the Company.

     The only periodic debt service obligation under the credit facility is to
make quarterly interest payments. Interest rates on borrowings under the credit
facility are based on the applicable LIBOR rate, or at the Company's election
the prime rate, in each case plus a spread that will vary depending on the
Company's credit rating and whether or not $1,500 of the debt is repaid, as
described below. For ratings of BB- from Standard & Poor's and Ba3 from Moody's,
the applicable interest rate at September 30, 2001 would be the applicable LIBOR
rate plus 350 basis points. In addition, prior to any repayment of $1,500 of the
debt, the interest rate will increase 25 basis points every ninety days from
February 22, 2001. The weighted average interest rate at September 30, 2001 was
7.11%. Upon any repayment of $1,500 of the debt, the interest rates on the
borrowings, assuming the credit rating remains the same, would return to the
applicable LIBOR rate plus 350 basis points.

     The credit facility contains customary restrictions, affirmative and
negative covenants and events of default for this type of collateralized
financing. These covenants include a maximum ratio of debt to earnings before
interest, taxes, depreciation and amortization and a minimum ratio of earnings
before interest, taxes, depreciation and amortization to interest expense.

     On October 4, 2001, the Company amended its credit facility. See Note 22
"Subsequent Events."

13.  TOTAL COMPREHENSIVE INCOME (LOSS)

     Total comprehensive income (loss), which is displayed in the consolidated
and combined statements of changes in stockholders' equity/invested equity and
total comprehensive income (loss), represents net income (loss) plus the results
of certain equity changes not reflected in the consolidated and combined
statements of operations.

     The foreign currency translation adjustments are not currently adjusted for
income taxes because they relate to indefinite investments in non-US
subsidiaries. There were also no income taxes provided for the unrealized gain
on investments. The unrealized loss on cash flow hedges was related to the SFAS
133 hedging activities by SMP, a joint venture with Chartered Semiconductor in
Singapore and there were no income taxes provided for the unrealized loss.

14.  STOCK COMPENSATION PLANS

     Certain employees of the Company have been granted stock options and other
equity-based awards under Lucent stock based compensation plans. At the time of
the Distribution, awards outstanding under Lucent's stock-based compensation
plans and held by Company employees will be converted to Company stock-based
awards. The stock options and other awards, as converted or adjusted, will have
the same vesting provisions, option periods, and other terms and conditions as
the Lucent options and awards they replace. The number of shares and exercise
price of each stock option will be adjusted so that following conversion, each
option will have the same ratio of the exercise price per share to the market
value per share, and the same aggregate difference between market value and
exercise price as the Lucent stock options prior to the conversion. No new
measurement date is expected to occur upon conversion of the stock options.

     Agere has stock-based compensation plans under which employees and outside
directors receive stock option and other equity-based awards. The plans provide
for the granting of stock options, performance awards, restricted stock awards
and other stock unit awards. During fiscal 2001, employees of the Company were
granted stock options and other equity-based awards under Agere's 2001 Long-Term
Incentive Plan. The Company has reserved 182 million shares for issuance under
these plans.

     Lucent stock options generally were granted with an exercise price equal to

Agere stock options are granted with an exercise price equal to 100% of the
market value of a share of common stock on the date of the grant, have
seven-year terms, and generally vest no later than four years from the date of
grant.

     In connection with certain of the Company's acquisitions, outstanding stock
options held by employees of acquired companies became exercisable, according to
their terms, for Lucent's common stock effective at the acquisition date. For
acquisitions accounted for as purchases, the fair value of these options was
included as part of the purchase price.

     Agere maintains an Employee Stock Purchase Plan (the "ESPP") with
consecutive offering periods, each consisting of four purchase periods of
approximately six months in length. The first offering period commenced on March
27, 2001 and ends April 30, 2003. Subsequent offering periods will run generally
for 24 months beginning May 1 of every other year. Under the terms of the ESPP,
participating employees may have up to 10% of eligible compensation (subject to
certain limitations) deducted from their pay to purchase the Company's common
stock. The per share purchase price is equal to 85% of the lower of either the
market price on the employee's entry date for the current offering period, or
the last trading day of each purchase period. The amount that may be offered
pursuant to this plan is 85 million shares. As of September 30, 2001, no shares
were purchased under the ESPP.

     Agere has adopted the disclosure requirements of SFAS No. 123, "Accounting
for Stock-Based Compensation" and, as permitted under SFAS No. 123, applies
Accounting Principles Board Opinion ("APB") No. 25 and related interpretations
in accounting for its plans. Compensation expense recorded under APB No. 25,
which uses the intrinsic value method, was $4, $1 and $1 for the years ended
September 30, 2001, 2000 and 1999, respectively. If Agere had elected to adopt
the optional recognition provisions of SFAS No. 123, which uses the fair
value-based method, for its stock option plans and ESPP, net income (loss) for
the Company would have been changed to the pro forma amounts indicated below:

# Effective with the spin-off of Avaya Inc. on September 30, 2000, the number of
  outstanding options was adjusted and all exercise prices were decreased
  immediately following the spin-off date to preserve the economic values of the
  options that existed prior to the spin-off.

     The weighted average fair value of the Agere stock options and Lucent stock
options held by Agere employees, is calculated using the Black-Scholes
option-pricing model. The weighted average fair value of Agere stock options
granted during fiscal 2001 was $2.43 per share, and for those granted by Lucent
during fiscal 2001, 2000 and 1999 was $7.36, $15.88 and $14.46 per share,
respectively.

15.  EARNINGS (LOSS) PER COMMON SHARE

     Basic and diluted earnings (loss) per common share is calculated by
dividing net earnings (loss) by the weighted average number of common shares
outstanding during the period. As a result of the net loss reported for the year
ended September 30, 2001, 1,170,969 of potential common shares have been
excluded from the calculation of diluted loss per share because their effect
would be anti-dilutive.

     In addition, at September 30, 2001, Agere employees held stock-based awards
covering approximately 46 million shares of Lucent common stock that may be
converted to Agere stock-based awards at the time of

the Distribution, if the Distribution occurs. The number of shares of Agere
common stock subject to substituted awards, if this conversion occurs, cannot be
determined at this time since the conversion ratio will be determined at the
Distribution based on the per share value of the Company's common stock in
relation to that of Lucent's common stock.

16.  BENEFIT OBLIGATIONS

     The Company's financial statements reflect the cost experienced for its
employees and retirees while included in the Lucent plans. Effective January 1,
2002, the Company will assume responsibility for all employee benefit plans
other than pension benefits. Following the Distribution, the Company will assume
responsibility for the pension benefits covering its active employees and
employees who retired subsequent to the IPO.

  PENSION AND POSTRETIREMENT BENEFITS

     Several pension plans cover substantially all full-time employees.
Retirement benefits under the plans are based on a career average or flat dollar
formula. The domestic plans are non-contributory. A cash balance program was
established for all companies acquired since October 1, 1996 that did not
participate in a defined benefit pension plan and all management employees hired
after January 1, 1999. The cash balance plan resembles a savings account.
Amounts are credited based on age and a percentage of earnings. Following
termination, the employee is entitled to receive the balance in the account in a
lump sum. Under the cash balance program, future increases in earnings will not
result in additional prior service costs. It is the Company's policy to fund the
plans on a current basis to the extent deductible under existing Federal tax
regulations. The employees in the cash balance pension plan are not eligible for
the postretirement benefit plan.

     Until the Distribution, the Company's U.S. employees will be participants
in Lucent's pension plans. At the Distribution, the Company will become
responsible for pension benefits for the active U.S. employees of the Company,
as well as U.S. employees who retired or terminated employment subsequent to the
IPO. Obligations related to employees who retired or terminated employment prior
to the IPO will remain the responsibility of Lucent. Following the Distribution,
Lucent will transfer to the Company the pension and postretirement assets and
liabilities related to these employees. Lucent has managed its U.S. employee
benefit plans on a consolidated basis and separate company information is not
readily available. The consolidated and combined statements of operations
include an allocation of the costs (benefits) of the U.S. pension and
postretirement plans. These costs were allocated based on the Company's U.S.
active employee population for each of the years presented.

     Effective October 1, 1998, Lucent changed its method for calculating the
market-related value of plan assets used in determining the expected
return-on-plan-assets component of annual net pension and postretirement benefit
costs. Under the previous accounting method, the calculation of the
market-related value of plan assets included only interest and dividends
immediately, while all other realized and unrealized gains and losses were
amortized on a straight-line basis over a five-year period. The new method used
to calculate market-related value includes recognizing immediately an amount
based on Lucent's historical asset returns and amortizes the difference between
that amount and the actual return on a straight-line basis over a five-year
period.

     The cumulative effect of this accounting change for Agere related to
periods prior to fiscal 1999 of $53 ($32 after-tax) is a one-time, non-cash
credit to fiscal 1999 earnings. This accounting change also resulted in a
reduction in benefit costs in fiscal 1999 that increased income by $10 ($6
after-tax) as compared with the previous accounting method.

     Lucent has several non-pension postretirement benefit plans. For
postretirement health care benefit plans, Lucent assumed an 8.6% weighted
average annual health care cost trend rate for 2002 gradually declining to 4.9%
(excluding postretirement dental benefits, the annual medical cost trend rate
would be 9.1% in 2002 gradually declining to 5.0%). The assumed health care cost
trend rate has a significant effect on the amounts reported. A one
percentage-point change in the assumed Lucent health care cost trend rate would
have the following effects, including discontinued operations:

  SAVINGS PLANS

     The majority of the Company's employees are eligible to participate in
savings plans sponsored by Lucent. The plans allow employees to contribute a
portion of their compensation on a pre-tax and/or after-tax basis in accordance
with specified guidelines. Lucent matches a percentage of employee contributions
up to certain limits. The Company's expense related to the Lucent savings plans
was $25, $21 and $25 in fiscal 2001, 2000 and 1999, respectively. The Company
expects to establish corresponding plans effective January 1, 2002.

17.  OPERATING SEGMENTS

     The Company has two reportable segments: Integrated Circuits and
Optoelectronics. Integrated circuits, or chips, are made using semiconductor
wafers imprinted with a network of electronic components. They are designed to
perform various functions such as processing electronic signals, controlling
electronic system

                                        75
<PAGE>
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

functions and processing and storing data. The Integrated Circuits segment
includes the Company's wireless local area networking products, which facilitate
the transmission of data and voice signals within a localized area without
cables or wires. The Optoelectronics segment represents the Company's
optoelectronic components operations, including both active optoelectronic
components and passive components. Optoelectronic components transmit, process,
change, amplify and receive light that carries data and voice traffic over
optical networks. Each of the Integrated Circuits and Optoelectronics segments
include revenue from the licensing of intellectual property related to that
segment. There were no inter-segment sales during the periods presented.

     Each segment is managed separately. Disclosure of segment information is on
the same basis used internally for evaluating segment performance and for
deciding how to allocate resources.

     The Company has centralized corporate functions and uses shared service
arrangements to realize economies of scale and efficient use of resources. The
costs of shared services, and other corporate center operations managed on a
common basis, are allocated to the segments based on usage or other factors
based on the nature of the activity. The accounting policies of the reportable
operating segments are the same as those described in Note 2 "Summary of
Significant Accounting Policies."

     Performance measurement and resource allocation for the segments are based
on many factors. The primary financial measure used is operating income (loss),
exclusive of the amortization of goodwill and other acquired intangibles, IPRD,
restructuring and separation expenses, and impairment of goodwill and other
acquired intangibles.

(1) Revenue is attributed to geographic areas based on the customer's shipped-to
    location, except for intellectual property license revenue which is
    attributed to the U.S. operations.

(2) Represents property, plant and equipment-net and goodwill and other acquired
    intangibles.

  CONCENTRATIONS

     Historically, the Company has relied on a limited number of customers for a
substantial portion of its revenue. Lucent accounted for 14.9%, 21.3% and 25.7%
of the Company's consolidated and combined revenue for fiscal 2001, 2000 and
1999, respectively. The Company expects that a significant portion of its future
revenue will continue to be generated by current customers and a limited number
of other customers. The

Company currently purchases some parts and processes used for its integrated
circuits and several different parts that are used in its optoelectronic
components, in each case for which there is only one qualified manufacturer.
While the Company is currently seeking alternative internal or external sources
of these parts and processes, disruption of its sole source could have a
material adverse effect on sales and shipments of the affected products.

18.  FINANCIAL INSTRUMENTS

  FAIR VALUES

     The carrying values and estimated fair values of cash and cash equivalents,
investments, receivables, payables and debt maturing within one year contained
in the consolidated and combined balance sheets approximate fair value.

     The carrying values of foreign exchange forward contracts at September 30,
2001 equal their fair value. The carrying values and estimated fair values of
foreign exchange forward contracts at September 30, 2000 was $0 for assets, and
$5 and $6, respectively for liabilities. The fair values of foreign exchange
forward contracts are determined using quoted market rates.

  CREDIT AND MARKET RISK

     By their nature, all financial instruments involve risk, including credit
risk for non-performance by counterparties. The Company seeks to reduce credit
risk on financial instruments by dealing only with financially secure
counterparties and reserves for losses are established when deemed necessary.
The Company seeks to limit its exposure to credit risks in any single country or
region.

     All financial instruments inherently expose the holders to market risk,
including changes in currency and interest rates. Agere manages its exposure to
these market risks through its regular operating and financing activities and
when appropriate, through the use of derivative financial instruments.

  DERIVATIVE FINANCIAL INSTRUMENTS

     The Company conducts its operations on a multinational basis in several
foreign currencies. Generally, foreign currency forward exchange contracts are
designated for firmly committed or forecasted sales and purchases that are
expected to occur in less than one year. Agere enters into various foreign
exchange forward contracts to manage its exposure to changes in those foreign
exchange rates. The Company's derivative financial instruments are used as risk
management tools and are not for trading purposes.

     The notional amounts for foreign currency forward exchange contracts
represent the U.S. dollar equivalent of an amount exchanged. As of September 30,
2001, Agere had outstanding hedges for British Pounds Sterling and Singapore
Dollars. The notional amounts for these contracts were $12 and $6, respectively.
The asset and liability fair values of these instruments were $0.

     Agere engages in foreign currency hedging activities as a defensive
strategy designed to protect the Company from adverse changes in foreign
currency exchange rates that may affect the eventual net cash flows resulting
from the sale of products to foreign customers and purchases from foreign
suppliers. Agere expects to continue to hedge foreign currency risk to preserve
the economic cash flows of the Company, but does not expect to designate related
derivative instruments as hedges for cost/benefit reasons. Accordingly, the
changes in fair value of these undesignated, freestanding foreign currency
derivative instruments are recorded in other income-net in the period of change
and have not been material to Agere.

     Prior to the adoption of SFAS 133 on October 1, 2000, foreign exchange
forward contracts were designated for firmly committed or forecast sales and
purchases that were expected to occur in less than one year. Gains and losses on
all hedged contracts for firmly committed transactions were deferred in other
current

                                        78

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

assets and liabilities, were recognized in other income-net when the
transactions occurred or were no longer probable and were not material to the
combined financial statements at September 30, 2000. All other gains and losses
on foreign exchange forward contracts were recognized in other income-net as the
exchange rates changed.

  LETTERS OF CREDIT

     The Company is a party to letters of credit that represent purchased
guarantees ensuring the Company's performance or payment to third parties in
accordance with specified terms and conditions which amounted to approximately
$17 and $20 as of September 30, 2001 and 2000. The estimated fair value of these
letters of credit were $0 as of September 30, 2001 and 2000, which is based on
fees paid to obtain the obligations.

19.  TRANSACTIONS WITH LUCENT

     Revenue from products sold to Lucent was $606, $1,002 and $955, in fiscal
2001, 2000 and 1999, respectively. Included in these amounts are revenues of $65
and $82 in fiscal 2000 and 1999, respectively, from sales to Avaya, which was
the enterprise networks business of Lucent until its spin off from Lucent on
September 30, 2000. Sales to Avaya after that date are not considered
transactions with Lucent. Products purchased from Lucent were $22, $23 and $1
for fiscal 2001, 2000 and 1999, respectively. In addition, Lucent billed the
Company $23, $67 and $49 for fiscal 2001, 2000 and 1999, respectively, for
specific research and development projects related to the Company's businesses.

     In connection with the Separation and Distribution, the Company and Lucent
entered into a Separation and Distribution Agreement (the "Separation and
Distribution Agreement") and related agreements, which are summarized below.
This summary is qualified in all respects by the terms of the Separation and
Distribution Agreement and the related agreements.

  SEPARATION AND DISTRIBUTION AGREEMENT

     The Separation and Distribution Agreement governs the transfer by Lucent to
the Company of all the assets, liabilities and operations associated with the
Company's Businesses.

     The Separation and Distribution Agreement, among other things, provides
that the Company will indemnify Lucent for all liabilities relating to the
Company's Businesses and for all contingent liabilities primarily relating to
the Company's Businesses. In addition, the Separation and Distribution Agreement
provides that certain contingent liabilities will be shared by Lucent and the
Company based on agreed upon percentages.

  EMPLOYEE BENEFITS AGREEMENT

     The Company and Lucent entered into an Employee Benefits Agreement,
pursuant to which the Company will create independent pension and other employee
benefit plans that are substantially similar to Lucent's existing pension and
other employee benefit plans. This agreement provides that, from the Separation
until the Distribution, the Company will be a "Participating Company" in
Lucent's employee benefit plans, other than Lucent's employee stock purchase
plan (after June 30, 2001), and will bear its allocable share of costs for
benefits and administration under these plans. Under the agreement and effective
immediately after the Distribution, Lucent will transfer the assets and
liabilities of various existing Lucent pension and other employee benefit plans
related to Agere employees. Generally, following the Distribution, Lucent will
cease to have any liability or obligation to the Company's current employees and
their beneficiaries under any of Lucent's benefit plans, programs or practices.

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

  FEDERAL, STATE AND LOCAL TAX ALLOCATION AGREEMENT

     The State and Local Income Tax Allocation Agreement and the Federal Tax
Allocation Agreement govern the allocation of state, local and federal income
taxes for periods prior to and including the date of the IPO, except that the
state and local income tax allocation agreement will continue to apply in
certain states until Lucent no longer owns at least 50% of the Company's stock.

  TAX SHARING AGREEMENT

     The Company and Lucent entered into a Tax Sharing Agreement, which governs
the Company's and Lucent's respective rights, responsibilities and obligations
after the Distribution with respect to taxes for the periods ending on or before
the Distribution. Generally, pre-Distribution taxes that are clearly
attributable to the business of one party will be borne solely by that party,
and other pre-Distribution taxes will be shared by the parties based on a
formula set forth in the Tax Sharing Agreement. In addition, the Tax Sharing
Agreement addresses the allocation of liability for taxes that are incurred as a
result of restructuring activities undertaken to implement the Separation. If
the Distribution fails to qualify as a tax-free distribution under Section 355
of the Internal Revenue Code because of an acquisition of the Company's stock or
assets, or some other actions taken by the Company, then the Company will be
solely liable for any resulting corporate taxes.

  FIBER, MICROELECTRONICS AND ORINOCO PRODUCT PURCHASE AGREEMENTS

     The Company and Lucent entered into a Fiber Product Purchase Agreement, a
Microelectronics Product Purchase Agreement and an ORiNOCO Product Purchase
Agreement. The pricing terms for the products and services covered by these
commercial agreements reflect negotiated prices. Under the Fiber Product
Purchase Agreement the Company has an obligation to purchase all of its
requirements of specified specialty fiber, fiber apparatus and premises cable
products from Lucent.

     The Microelectronics Product Purchase Agreement governs purchases of goods
and services by Lucent from the Company. Under the agreement, Lucent committed
to purchase at least $2,800 of products from the Company over a three-year
period beginning February 1, 2001. In limited circumstances, Lucent's purchase
commitment may be reduced or the term may be extended. For the period February
1, 2001 through September 30, 2001, Lucent's purchases under this agreement were
$325. In light of Lucent's purchases to date and adverse market conditions, the
Company is discussing with Lucent ways to restructure Lucent's obligations under
the agreement.

     The ORiNOCO Product Purchase Agreement governs transactions in which the
Company furnishes ORiNOCO products to Lucent for resale. The agreement does not
grant to Lucent an exclusive right to resell the products, but does grant Lucent
a right of first opportunity or refusal for certain specified service provider
customers in exchange for a minimum purchase commitment. The pricing in the
agreement is based on the Company's list price in effect on the date of the
receipt of an order less any applicable discounts.

  INTERIM SERVICES AND SYSTEMS REPLICATION AGREEMENT

     The Company and Lucent entered into an Interim Service and Systems
Replication Agreement to provide each other, on an interim, transitional basis,
with various data processing services, telecommunications services and corporate
support services, including: accounting, financial management, information
systems management, tax, payroll, legal, human resources administration,
procurement and other general support. This agreement also provides for the
replication and transfer of designated computer systems used for administrative
support or used in the Company's Businesses or Lucent's other businesses. The
systems include specified hardware, software, data storage or maintenance and
support components. Costs and expenses of purchasing hardware or obtaining
software are borne by the party purchasing the hardware or licensing the
software. The costs associated with this agreement amounted to $73 for the year
ended September 30, 2001.

<PAGE>
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

  REAL ESTATE AGREEMENTS

     Lucent and the Company entered into various leases and sublease
arrangements for the sharing of certain facilities for a transitional period on
commercial terms. The lease term for space in owned buildings was determined on
a case-by-case basis. In the case of subleases or sub-subleases of property, the
lease term generally coincides with the remaining term of the primary lease or
sublease, respectively.

  TRADEMARK LICENSE AGREEMENT, TRADEMARK ASSIGNMENT AND TRADE DRESS ASSIGNMENT

     The primary trademarks used in the sale of the Company's products and
services were transferred to the Company, except for Lucent's name and logo and
the Bell Laboratories name. The Company may use the Lucent name and logo, but
not the Bell Laboratories name, on a royalty-free basis, for a transitional
period. Lucent and the Company entered into a Trademark License Agreement,
Trademark Assignment and Trade Dress Assignment to effectuate the grant or
transfer, as applicable, of such rights.

  PATENT ASSIGNMENTS

     The Company and Lucent executed patent assignments and other agreements
related to patents owned or controlled by Lucent. The patent assignments divided
ownership of patents, patent applications and foreign counterparts between the
Company and Lucent. Lucent transferred to Agere ownership of or exclusive rights
in certain patents and patent applications held by Lucent before the Separation
that relate principally to the Company's Businesses. Lucent retained ownership
of all other patents and patent applications.

  TECHNOLOGY ASSIGNMENT AND JOINT OWNERSHIP AGREEMENT

     The Company and Lucent executed assignments and other agreements, including
the technology assignment, related to technology owned or controlled by Lucent
and its subsidiaries. Technology included copyrights, mask works and other
intellectual property other than trademarks, trade names, service marks and
patent rights. The technology assignment generally divided ownership of
technology between the Company and Lucent, with each owning technology that was
developed by or for, or purchased for the respective businesses of each company.
Certain specified technology is owned jointly by the Company and Lucent.

  PATENT AND TECHNOLOGY LICENSE AGREEMENT

     The Company and Lucent entered into a Patent and Technology License
Agreement related to patents and technology owned or controlled by the Company
and Lucent. The Patent and Technology License Agreement provides for
cross-licenses to each company. The Company and Lucent granted to each other,
under the patents that each company has, a nonexclusive, personal,
nontransferable license to make, have made, use, lease, import, offer to sell,
and sell any and all products and services of the businesses in which the
licensed company, including related companies, is now or hereafter engaged. The
cross-licenses also permit each company, subject to limitations, to have third
parties make items under the other company's patents, as well as to pass through
to customers limited rights under the other company's patents with respect to
products and services furnished to customers by the licensed company. Certain
patents are licensed exclusively to each party, including the right to grant
sublicenses, subject to retention of a right to use those patents by the
licensing party. Otherwise, the right to sublicense to unaffiliated third
parties was not granted under the cross-licenses, except for limited rights in
connection with establishing second source suppliers, performing joint
development activities and rights to sublicense a divested business. The
cross-licenses between the Company and Lucent cover all of each company's
patents, including patents issued on patent applications with a filing date
prior to February 1, 2003. The Patent and Technology License Agreement also
grants to the Company a joint ownership interest to a limited number of patents
and patent applications.

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

  DEVELOPMENT PROJECT AGREEMENT

     Lucent and the Company entered into a Development Project Agreement under
which Bell Laboratories performs certain research and development activities for
the Company on a contract basis. The Company also performs research and
development activities for Lucent on a contract basis.

  JOINT DESIGN CENTER OPERATING AGREEMENT

     Lucent and the Company entered into a Joint Design Center Operating
Agreement to develop technology for micro electro-mechanical systems, or MEMS.

20.  COMMITMENTS AND CONTINGENCIES

     In the normal course of business, the Company is involved in proceedings,
lawsuits and other claims, including proceedings under laws and government
regulations related to environmental, tax and other matters. The semiconductor
industry is characterized by substantial litigation concerning patents and other
intellectual property rights. From time to time, the Company may be party to
various inquiries or claims in connection with these rights. These matters are
subject to many uncertainties, and outcomes are not predictable with assurance.
Consequently, the ultimate aggregate amount of monetary liability or financial
impact with respect to these matters at September 30, 2001 cannot be
ascertained. While these matters could affect the operating results of any one
quarter when resolved in future periods and while there can be no assurance with
respect thereto, management believes that after final disposition, any monetary
liability or financial impact to the Company beyond that provided for at
September 30, 2001, would not be material to the annual consolidated financial
statements.

     In December 1997, the Company entered into a joint venture, called SMP,
with Chartered Semiconductor, a leading manufacturing foundry for integrated
circuits, to operate a 54,000 square foot integrated circuit manufacturing
facility in Singapore. The Company owns a 51% equity interest in this joint
venture, and Chartered Semiconductor owns the remaining 49% equity interest. The
Company has an agreement with SMP under which it has agreed to purchase 51% of
the production output from this facility and Chartered Semiconductor agreed to
purchase the remaining 49% of the production output. If the Company fails to
purchase its required commitments, it will be required to pay SMP for the fixed
costs associated with the unpurchased wafers. Chartered Semiconductor is
similarly obligated with respect to the wafers allotted to it. The agreement
also provides that Chartered Semiconductor will have the right of first refusal
to purchase integrated circuits produced in excess of the Company's
requirements. The agreement may be terminated by either party upon two years
written notice, but may not be terminated prior to February 2008. The agreement
may also be terminated for material breach, bankruptcy or insolvency.

     In July 2000, the Company and Chartered Semiconductor entered into an
agreement committing the Company and Chartered Semiconductor to jointly develop
manufacturing technologies for future generations of integrated circuits
targeted at high-growth communications markets. The Company has agreed to invest
up to $350 over a five-year period. As part of the joint development activities,
the two companies will staff a new research and development team at Chartered
Semiconductor's Woodlands campus in Singapore. These scientists and engineers
will work with Company teams in Murray Hill, New Jersey, and Orlando, Florida,
as well as with Chartered Semiconductor's technology development organization,
to create a 600-person research and development team. The agreement may be
terminated for breach of material terms upon 30 days notice or for convenience
upon six months notice prior to the planned successful completion of a
development project, in which case the agreement will terminate upon the actual
successful completion of that project.

  RISKS AND UNCERTAINTIES

     The Company has a limited history operating as a stand-alone company, and
it may be unable to make the changes necessary to operate as a stand-alone
company, or it may incur greater costs as a stand-alone
                                        82
<PAGE>
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

company. Until early 2001, the Company's businesses were operated by Lucent as a
segment of its broader corporate organization rather than as a separate
stand-alone company. Lucent assisted the Company by performing various corporate
functions, including public relations, employee relations, investor relations,
finance, legal and tax functions. Lucent continues to provide some of these
functions to the Company on an interim basis pursuant to the Interim Services
and Systems Replication Agreement.

     As of September 30, 2001, the Company's primary source of liquidity was its
cash and cash equivalents. The Company believes this cash, together with cash
flow from operations, will be sufficient to meet its cash requirements at least
through the end of fiscal 2002, including repayment of borrowings under the
credit facility if its maturity is not extended. If the Company's revenues are
materially lower than what is contemplated in its outlook, the Company will
further reduce expenditures in an effort to meet its cash requirements. The
Company also intends to seek additional funds from liquidity generating
transactions and capital markets financings, although it cannot provide any
assurance that any of these transactions or financings will be available to it
on acceptable terms or at all.

  LEGAL PROCEEDINGS

     From time to time, the Company is involved in legal proceedings arising in
the ordinary course of business, including unfair labor charges filed by its
unions with the National Labor Relations Board, claims before the U.S. Equal
Employment Opportunity Commission and other employee grievances. The Company
also may be subject to intellectual property litigation and infringement claims,
which could cause it to incur significant expenses or prevent it from selling
its products.

     On October 3, 2000, a patent infringement lawsuit was filed against Lucent,
among other optoelectronic components manufacturers, by Litton Systems, Inc. and
The Board of Trustees of the Leland Stanford Junior University in the United
States District Court for the Central District of California (Western Division).
The Company anticipates that it may be named a defendant in the suit. The
complaint alleges that each of the defendants is infringing a patent related to
the manufacture of erbium-doped optical amplifiers. The patent is owned by
Stanford University and is exclusively licensed to Litton. The complaint seeks,
among other remedies, unspecified monetary damages, counsel fees and injunctive
relief. This matter is in its early stages.

     An investigation was commenced on April 4, 2001, by the U.S. International
Trade Commission based on a request of Proxim, Inc. alleging patent infringement
by 14 companies, including some of the Company's customers for wireless local
area networking products. Proxim alleges infringement of three patents related
to spread-spectrum coding techniques. Spread-spectrum coding techniques refers
to a way of transmitting a signal for wireless communications by spreading the
signal over a wide frequency band. The Company believes that it has valid
defenses to Proxim's claims and has intervened in the investigation in order to
defend its customers. Proxim seeks relief in the form of an exclusion order
preventing the importation of specified wireless local area networking products,
including some of the Company's products, into the United States. One of the
Company's subsidiaries, Agere Systems Guardian Corp., filed a lawsuit on May 23,
2001, in the U.S. District Court in Delaware against Proxim alleging
infringement of three patents used in Proxim's wireless local area networking
products.

     If the Company is unsuccessful in resolving these proceedings, as they
relate to the Company, its operations may be disrupted or it may incur
additional costs. Other than as described above, the Company does not believe
there is any litigation pending that should have, individually or in the
aggregate, a material adverse effect on its financial position, results of
operations or cash flows.

  ENVIRONMENTAL, HEALTH AND SAFETY

     The Company is subject to a wide range of U.S. and non-U.S. governmental
requirements relating to employee safety and health and to the handling and
emission into the environment of various substances used in its operations. The
Company also is subject to environmental laws, including the Comprehensive
                                        83

Environmental Response, Compensation and Liability Act, also known as Superfund,
that require the cleanup of soil and groundwater contamination at sites
currently or formerly owned or operated by the Company, or at sites where the
Company may have sent waste for disposal. These laws often require parties to
fund remedial action at sites regardless of fault. Lucent is a potentially
responsible party at numerous Superfund sites and sites otherwise requiring
cleanup action. With some limited exceptions, under the Separation and
Distribution Agreement with Lucent, the Company has assumed all environmental
liabilities resulting from the Company's Businesses, which include liabilities
for the costs associated with eight of these sites -- five Superfund sites, two
of the Company's former facilities and one of the Company's current
manufacturing facilities.

     It is often difficult to estimate the future impact of environmental
matters, including potential liabilities. The Company has established financial
reserves to cover environmental liabilities where they are probable and
reasonably estimable. This practice is followed whether the claims are asserted
or unasserted. Management expects that the amounts reserved will be paid out
over the period of remediation for the applicable site, which typically ranges
from five to thirty years. Reserves for estimated losses from environmental
remediation are, depending upon the site, based primarily upon internal or third
party environmental studies, estimates as to the number, participation level and
financial viability of all potentially responsible parties, the extent of the
contamination and the nature of required remedial actions. Accruals will be
adjusted as further information develops or circumstances change. The amounts
provided for in the consolidated and combined financial statements for
environmental reserves are the gross undiscounted amount of such reserves,
without deductions for insurance or third party indemnity claims. Although the
Company believes that its reserves are adequate, including those covering the
Company's potential liabilities at Superfund sites, there can be no assurance
that expenditures which will be required relating to remedial actions and
compliance with applicable environmental laws will not exceed the amounts
reflected in these reserves or will not have a material adverse effect on the
Company's financial condition, results of operations or cash flows.

  LEASES

     The Company leases land, buildings and equipment under agreements that
expire in various years through 2006. Rental expense under operating leases was
$133, $97 and $58 for the fiscal years ended September 30, 2001, 2000 and 1999,
respectively. The table below shows the future minimum lease payments due under
non-cancelable leases at September 30, 2001. Such payments total $331 for
operating leases. The net present value of such payments on the capital lease
obligation was $49 after deducting imputed interest of $6.

22.  SUBSEQUENT EVENTS (UNAUDITED)

  AMENDMENT OF CREDIT FACILITY

     On October 4, 2001, the Company and its lenders amended its credit
facility. In connection with the amendment, the Company repaid $1,000 of the
$2,500 then outstanding, reducing the facility to $1,500. The facility is
comprised of term loans and revolving credit loans and is secured by the
Company's principal domestic assets other than the proceeds of the IPO and while
Lucent remains a majority stockholder, real estate. The maturity date of the
facility has been extended from February 22, 2002 to September 30, 2002. In
addition, if the Company raises at least $500 in equity or debt capital markets
transactions before September 30, 2002, the maturity date of the facility will
be extended to September 30, 2004, with the facility required to be reduced to
$750 on September 30, 2002 and $500 on September 30, 2003. The debt is not
convertible into any other securities of the Company.

     The interest rates applicable to borrowings under the facility are based on
a scale indexed to the Company's credit rating. Based upon ratings of BB- from
Standard & Poor's and Ba3 from Moody's, the interest rate under the facility is
currently the applicable LIBOR rate plus 475 basis points. In addition, until

                                        85

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
                 (DOLLARS IN MILLIONS EXCEPT PER SHARE AMOUNTS)

the Company permanently reduces the size of the facility to $1,000, the
applicable interest rate will increase by an additional 25 basis points every
ninety days, with the next increase taking effect on February 17, 2002. If the
Company permanently reduces the size of the facility to $1,000, the interest
rate for borrowings under the facility, assuming the Company's credit ratings
remain the same, would drop to the applicable LIBOR rate plus 400 basis points.
The only periodic debt service obligation under the amended credit facility is
to make quarterly interest payments.

     Under the agreement, Agere must use proceeds of certain liquidity raising
transactions, asset sales outside the ordinary course of business and capital
markets transactions to reduce the size of the facility. If Agere completes the
liquidity raising transactions or sells assets outside the ordinary course of
business, it must apply 100% (50% if the size of the facility is $500 or less)
of the net cash proceeds it receives from the transaction to reduce the size of
the facility. The agreement also provides that 50% of the net cash proceeds of
the first $500 and 75% (50% if the size of the facility is $500 or less) of the
net cash proceeds greater than $500 from equity and debt capital markets
transactions be applied to reduce the credit facility. Notwithstanding the
foregoing, the Company must apply 100% of net cash proceeds over $1,000 from the
issuance of debt securities that are secured equally with the credit facility to
reduce the size of the credit facility.

     The financial covenants in the original agreement have been replaced with
new covenants. The new covenants require Agere (1) to maintain a minimum level
of liquidity, (2) to achieve a minimum level of earnings before interest, taxes,
depreciation and amortization computed in accordance with the agreement each
quarter, (3) to maintain a minimum level of net worth and (4) to limit its
capital expenditures. Other covenants restrict the Company's ability to pay cash
dividends, incur indebtedness and invest cash in its subsidiaries and other
businesses.

  BUSINESS RESTRUCTURING

     On December 5, 2001, the Company announced its intention to further reduce
its workforce by approximately 950 employees. The workforce reduction was
undertaken to align the Company's business with current market conditions. The
positions affected are primarily management positions within the Company's
product groups, sales organizations and corporate support functions located in
New Jersey and Pennsylvania. The Company expects to complete the workforce
reduction and recognize a related charge by the end of fiscal 2002.

  SALE OF FPGA BUSINESS

     On December 7, 2001, the Company entered into an agreement to sell certain
assets and liabilities related to the field-programmable gate array ("FPGA")
business of the Integrated Circuits segment to Lattice Semiconductor Corporation
("Lattice") for $250 in cash. The Company's FPGA business consists of its
general-purpose ORCA(TM) FPGA product portfolio, field-programmable system chip
product portfolio and related software design tools. As part of the sale,
approximately 100 employees will transfer to Lattice. The sale is expected to
close in the second quarter of fiscal 2002, subject to regulatory approval and
other customary closing conditions.
