Gigabit Ethernet and Fibre Channel transmission standards. In these markets,
the Company provides physical layer products such as transceivers, crosspoint
switches and Clock Recovery and Synthesis Units, physical media dependent
products such as transimpedance amplifiers and laser drivers, and overhead
processor products such as framers and mappers. The Company currently supplies
products for the Sonet OC-3, OC-12 and OC-48 transmission standards, and is
currently developing an OC-192 chip set. The Company also leverages its
technology to provide solutions for the ATE, broadcast HDTV, high-speed
computing and military markets. Customers of the Company include 3Com,
Alcatel, Cisco Systems, Marconi Communications, Lucent, Nortel, Raytheon
Systems, Seimens and Teradyne.

Industry Background

The Communications Industry

Communications technology has evolved from simple analog voice signals
transmitted over networks of copper telephone lines to complex analog and
digital voice and data transmitted over hybrid networks of media such as
copper, coaxial and fiber optic cables. This evolution has been driven by
enormous increases in the number of users and the complexity of the data types
transmitted over networks. In addition, the substantial growth in the
Internet, the World Wide Web, cellular and facsimile communications; the
emergence of new applications such as video conferencing; and the increase in
demand for remote network access and higher speed, higher bandwidth
communication between local area networks and local and wide area networks
have increased network bandwidth requirements. This increase has made many
systems architectures inadequate.

In the wide area network ("WAN") market, service providers and equipment
suppliers in particular have been impacted by the inadequacy of systems
architectures caused by the current public network infrastructure. This
infrastructure was designed to optimize voice communications and is not well
suited for the high-throughput requirements of data transmission that is
transmitted in "bursts." The volume and complexity of this data has led to the
increasing deployment of fiber optic technology for use in wide area networks
("WANs"). This technology has substantially greater transmission capacity and
is less error prone and easier to maintain than copper networks. The
Synchronous Optical Network ("SONET") standard in North America and Japan, and
the Synchronous Digital Hierarchy ("SDH") standard in the rest of the world,
have emerged as the standards for the transmission of signals over optical
fiber. The SONET/SDH standards facilitate high data integrity and

1

improved network reliability, while reducing maintenance and other operation
costs by standardizing interoperability among equipment from different
vendors. A transmission protocol complementary to SONET/SDH, Asynchronous
Transfer Mode ("ATM"), has emerged to optimize bandwidth utilization. ATM is a
network transmission protocol that packages data into fixed sized cells
enabling the support of not only data traffic, but delay-sensitive voice,
video and imaging applications.

In the local area network ("LAN") market, similar bandwidth issues have
arisen as the greater computational power of PCs have enabled powerful network
applications such as video conferencing and Web communications. However, these
new applications and the increasing number of computers on networks have
significantly increased the volume of data traffic and, as a result, the
network has now become the bottleneck in the delivery of integrated video,
audio and data. Ethernet is currently the most widespread LAN standard,
operating at 10 to 100 megabits per second. However, LAN backbones are rapidly
being upgraded to Gigabit Ethernet and ATM in order to increase available
bandwidth. These network protocols, which enable expanded bandwidth in excess
of one gigabit per second, are emerging as the new standards for LAN
backbones. In addition, the Fibre Channel standard, which also facilitates
data transmission at rates exceeding one gigabit per second, has emerged as a
practical, cost-effective and expandable method for achieving high-speed,
high-volume data transfer among workstations, mainframes, data storage devices
and other peripherals. Fibre Channel and Gigabit Ethernet are complementary
and compatible transmission standards, and the emergence of Gigabit Ethernet
has accelerated the growth of the Fibre Channel standard.

The Communications IC Opportunity

In order to address the growing requirements of communications networks,
equipment suppliers are having to develop and introduce increasingly
sophisticated systems at a rapid rate. To achieve the performance and
functionality required by such systems, these OEMs must utilize increasingly
complex integrated circuits ("ICs"), which now account for a larger portion of
the value-added proprietary content of such systems. As a result of the rapid
pace of new product introductions, the proliferation of standards to be
accommodated and the difficulty of designing and producing requisite ICs,
equipment suppliers increasingly outsource these ICs to semiconductor firms
with specialized expertise. These trends have created a significant
opportunity for IC suppliers that can design cost-effective solutions for the
transmission of high-frequency data. Dataquest estimates that the worldwide
SONET/SDH/ATM markets for ICs were approximately $670 million in 1998 and will
increase to approximately $1.7 billion in 2002. The Fibre Channel and Gigabit
Ethernet markets combined were approximately $70 million in 1998 and Dataquest
estimates that such combined markets will be approximately $190 million in
2002.

IC suppliers must utilize a variety of skills and technologies to satisfy
the requirements of communications equipment OEMs. These OEMs require IC
suppliers that possess system-level expertise and can quickly bring to market
high-performance, highly reliable, power-efficient ICs. Additionally, these
OEMs seek suppliers with both analog and digital expertise to provide a more
complete solution that enables faster integration into the system design and
higher performance. In particular, WAN OEMs require IC suppliers to provide
solutions that minimize jitter (a measure of the stability and noisiness of a
signal), which degrades transmission quality over distance. LAN products
typically have substantially shorter life cycles than WAN products, and the
rate of new product introductions is very high. Therefore, LAN OEMs
specifically require IC suppliers that can provide IC solutions that
accommodate these increased time-to-market demands. Furthermore, the LAN
market is highly cost driven and generally involves large volumes. Therefore,
OEMs in this market require IC suppliers that can provide increasingly lower
cost IC solutions that can quickly be ramped into high-volume production.

In the high-performance IC market, a number of process technologies are used
to produce ICs. Traditionally, designers have relied on silicon-based
manufacturing process technologies for the development of high-speed, mixed-
signal, analog and digital circuits with precision timing. In some cases, OEMs
utilize discrete components or IC solutions based on non-silicon processes
such as gallium arsenide ("GaAs") to meet the high-frequency requirements of
certain communications products. However, non-silicon processes tend to be
more expensive, less predictable with respect to yields and less able to ramp
to high-volume production than silicon processes.

AMCC Strategy

AMCC's objective is to be the leading supplier of high-performance, high-
bandwidth connectivity IC solutions for the world's communications
infrastructure. To achieve this objective, the Company employs the following
strategies:

Focus on High-Growth Wide Area Network Markets

AMCC targets key high-growth WAN markets, including those for SONET/SDH and
ATM products. The Company has built substantial competencies focused on the
specific requirements of these markets in the areas of process technology and
mixed-signal design and substantial expertise in systems architecture and
applications support. The Company believes that the integration of these
capabilities enables it to optimize solutions addressing the high-bandwidth
connectivity requirements of WAN systems OEMs. Additionally, AMCC leverages
its design expertise, process technologies and systems capabilities in WAN
markets to address specific customer requirements in the fiber optic portion
of the LAN markets.

Provide Complete System Solutions to the Customer and Aggressively Integrate
Products

AMCC's strategy in the WAN market is two fold; 1) provide fiber to switch
silicon solutions and; 2) continue to optimize these solutions through
integration. To this end, in April 1998, AMCC acquired Ten Mountains Design
which develops analog designs for physical media dependent ("PMD") devices. In
March 1999, AMCC acquired Cimaron Communications Corporation providing the
Company with expertise in the development of overhead processor products
("OHP") and system level design. The Company believes that these acquisitions,
together with AMCC's established competence in the high-speed mixed-signal (or
physical layer) development, now allow AMCC to offer comprehensive solutions
for communications equipment OEMs from the fiber to the switch. This provides
our customers with guaranteed interoperability, pre-designed subsystems,
better-cost economics, and system level expertise. The result is faster time
to market, better performance and lower cost. To continue these customer
benefits in future generations of products, AMCC is pursuing an aggressive
integration strategy to provide greater functionality in fewer IC's.

Capitalize on Multiple Silicon-Process Technologies to Provide Optimized
Solutions

The Company is dedicated to utilizing the best silicon process technology
available to offer solutions optimized for specific applications and customer
requirements. The Company has successfully developed multiple generations of
its processes and believes that it will be able to continue the evolution of
its processes to deliver the performance required of future communications
ICs. AMCC believes its current and future bipolar and BiCMOS processes and
design expertise, complemented by advanced CMOS and silicon germanium ("SiGe")
BiCMOS processes from external foundries, provide the Company with the
flexibility to design and manufacture products that are tailored to its
customers' individual needs. Through this flexible approach, AMCC is better
able to transition products over time to new manufacturing processes as
product performance requirements and process technologies evolve.

Capitalize on Established Silicon-Process Technologies to Provide Cost-
Effective Solutions

The Company applies its systems expertise and its analog, mixed-signal and
digital design techniques to architect high-performance products based on
established silicon process technologies. The Company believes that these
silicon-based processes are proven, stable and predictable relative to non-
silicon processes and benefit from the extensive semiconductor industry
infrastructure devoted to the support of silicon processes.

Products and Customers

AMCC designs, develops, manufactures and markets high-performance, high-
bandwidth silicon solutions for the world's communications infrastructure. The
Company's current IC products primarily address the needs

3

of the fiber optic based WAN and LAN markets. The Company's products for this
market are designed to respond to the growing demand for high-speed networking
applications for established WAN standards such as SONET/SDH and ATM and LAN
standards such as Gigabit Ethernet, ATM and Fibre Channel. The Company also
markets and sells IC products that address the needs of the ATE, broadcast
HDTV, high-speed computing and military markets. The Company utilizes its
high-performance design expertise and systems knowledge, together with its
internal bipolar and BiCMOS processes and CMOS and SiGe processes from outside
foundries, to design and manufacture products that are tailored to its
customers' individual needs.

The Company uses its design methodologies to develop a platform product and
leverage that product into multiple derivative products that are highly
optimized for specific applications. For example, the Company recently
developed the S3019, a SONET/SDH OC-12 transceiver, as a platform for 5
products in its S303X family. By reusing significant portions of the platform
design, the Company can reduce develop time, risk and costs. This is
especially important in analog intensive circuitry such as very low jitter
phase locked loops ("PLLs").

The following table summarizes the product types AMCC offers in the
communication markets:

X = AMCC currently produces or has sampled products in this market.
Z = AMCC is actively developing products in this market.

Analog Layer (or PMD): AMCC's analog layer products interface directly to
the lasers or photo diodes that provide the electrical to optical and optical
to electrical conversions. These products include various amplifiers that take
very weak electrical signals (e.g. a few millivolts) and amplify into more
traditional digital level signals (e.g. hundreds of millivolts). AMCC's
efforts in these areas are focused at the high end ranging from 1 to 10 Gbps.

Mixed Signal Layer (or physical layer): AMCC's mixed signal products
transmit and receive data from the PMD layer in a very high-speed serial
format (up to 10Gbps). They are one of the most key elements in the control of
overall system jitter, a measure of the "noisiness" of the signal. Low noise
enables transmission of data over greater distances with fewer errors. The
system clock is also generated or recovered in these devices. Data is
converted from a high-speed serial format to a lower-speed parallel interface
that can be handled by the digital layer. Data is also received on the lower-
speed parallel interface (digital layer) and serialized into a high-speed
format and handed to the PMD layer.

Digital Layer (or overhead processors ("OHP")): AMCC's digital layer
products receive and transmit data from the physical (or mixed signal) layer
in a parallel format. These products then perform a number of functions
including framing, terminating the overhead, performance monitoring, and
mapping the data payload to/from the transmission format. The data is then
available to be sent to a switch core or handed off for additional processing
(grooming, traffic shaping, policing, etc). AMCC's digital layer products are
found predominately in systems such as very high-speed add-drop multiplexers,
digital cross-connects, terabit routers and dense wave division multiplexers
("DWDM").

WAN Products

WAN Analog Products: Over the past year AMCC introduced its first generation
of PMD products for the OC-48 (2.488 Gbps) market. The S3049 (laser driver)
and S3051 (post amplifier) were developed on AMCC's internal bipolar
technology. Additional OC-48 and OC-192 PMD products are currently under
development in a SiGe process.

WAN Mixed Signal Products: AMCC introduced its first generation of SONET OC-
12 (622 Mbps) products in 1993. The Company has since developed 3 additional
generations of these products, each integrating greater functionality on each
chip while improving jitter performance. For example, the Company's first
generation of these products consisted of transmitter/receiver pairs with dual
voltage. The second generation consisted of products that are compatible with
single +5 volt optical modules. The Company's third generation physical layer
product was a single chip transceiver operating at a single +3.3 volt power
supply. This product offers systems OEMs selectable reference frequencies, a 4
or 8-bit data path, a PECL or TTL level interface, a diagnostic mode and
special failure indicators. The Company's fourth generation, the S3038,
incorporated 4 transceivers and utilized 5 PLL's in a single device. The S3038
was the Company's first SONET/SDH physical layer device implemented in CMOS
from an external foundry.

Over the past year the Company completed a first generation of OC-48 (2.5
Gbps) mixed signal devices. The S3043 and S3044 chipset operating off a single
+3.3 volt supply offered the industry's lowest power solution for CSU, mux and
demux functions. Additionally the Company introduced the S3050, a multi-rate
CDR, which performs clock and data recovery on OC-3 (155Mbps), OC-12
(622Mbps), gigabit ethernet (1.25 Gbps) or OC-48 (2.488 Gbps) data rates. The
Company is currently developing its second generation of these products as
well as solutions for OC-192.

WAN Digital Layer Products: In the past year AMCC introduced its first
generation of digital layer products for the OC-48 market. The first of these
products, the S3045, performs the mux/demux functions for an OC-48 payload
into four OC-12 payloads. With the acquisition of Cimaron Communications in
March 1999, the Company has subsequently introduced 3 additional digital layer
products, the Congo with OC-12 packet-over-SONET, the Nile with integrated OC-
12 to DS-3 mapping, and the Amazon with fully functional packet-over-SONET for
OC-48. All of these devices can be utilized with the Company's mixed signal
and analog layer products providing a very comprehensive solution set. The
Company is currently developing second generations and OC-192 digital layer
products.

Serial Backplane Products. In addition to the WAN and LAN network equipment
and standards developed to address the issue of network bandwidth, network
equipment OEMs must also ensure that once high-frequency signals exit the
transmission network, they can be switched efficiently, while taking full
advantage of the available bandwidth. Backplanes (the boards that distribute
signals to various ports of a switching system) are currently emerging as a
serious constraint for systems OEMs because redesigning the traditional
architecture of parallel channels to accommodate higher frequency signals is
prohibitively expensive. Therefore, serial channels, which can accommodate
much higher frequencies, are being increasingly employed. The Company believes
that this transition has created a significant opportunity for suppliers that
can design IC solutions enabling the transmission of high-frequency data
through a serial backplane. In May 1998, the Company introduced the S2064, a
quad transceiver implemented in 0.35 micron CMOS. The S2064 is a platform
product that the company has used to develop and introduce 7 other products.
The Company is currently developing higher bandwidth serial backplane
products.

Current customers in the WAN market which the Company ships production
products and/or has commenced development programs with include 3Com, Alcatel,
Ciena, Cisco, ECI, Ericson, FORE, Fujitsu, Hitachi, Lucent, Marconi, Monterey,
NEC, Nokia, Nortel, Pirelli, Siemens, Sycamore, Tellabs, and Tellium. All of
the Company's communications devices are supported with evaluation boards and
design aids to facilitate easy integration into system architectures.

5

LAN Products

LAN Analog Products: Over the past year AMCC introduced its first PMD
products for the gigabit ethernet and fibre channel standards. The S7011
vertical cavity surface emitting laser driver offers digital programmability
for laser trimming, which greatly reduces the number of external components
and system integration time.

LAN Mixed Signal Products: AMCC introduced its first physical layer products
in the gigabit ethernet and fibre channel markets in 1995. The Company has
since developed 3 generations of products that support both +5 and +3.3 volt
and today range from a single channel transceiver to quad channel
transceivers.

Current customers in the LAN market which the company ships production
products and/or has commenced development programs with include 3Com,
Cabletron Systems, Cisco, Compaq, Digital Equipment Corporation, FORE,
Fujikura, Fujitsu, Hewlett-Packard, IBM, Lucent, Newbridge Networks, Nortel,
Siemens, Sun Microsystems, Tellabs and Vixel.

ATE

AMCC introduced its current generation gate array Q20000 family of products
in 1991 and its Micropower-based standard cell products in 1993. Micropower,
one of the first products to offer +3.3V operation for high performance ASICs,
uses AMCC's proprietary bipolar process. The high-performance and low-power
characteristics of this family of products make it particularly suitable for
high performance semiconductor ATE applications that require approximately
4,000 equivalent gates, low jitter and precision circuits. Current customers
for the Company's products for the ATE market include Hewlett-Packard, LTX,
Schlumberger, Teradyne and Texas Instruments.

High-Speed Computing Products

AMCC offers a PCI product line that address the high-speed computing market.
The S5933 is a standard master/slave PCI controller chip. The S5920 is a
standard target-only PCI controller chip. These devices are supported with
comprehensive development kits and third-party driver software. The Company
sells these products to a very large and diverse customer base. Current
customers of the Company's products include Cisco Systems, Ericsson, IBM and
SAT. The Company's S5933 PCI controller chip is also used in reference designs
with C-Cube Microsystems for digital video disk products.

Military

The Company's Q20000 gate array family of ASIC products are well suited for
military applications and as replacements for ECLinPS(TM) logic from Motorola.
The Company sells ASICs to military customers such as Northrop Grumman,
Raytheon Systems Co. and Rockwell International.

Technology

The Company utilizes its technological and design expertise to solve the
unique problems of high-speed analog, digital and mixed-signal circuit designs
for the world's communications infrastructure. The Company's competencies
include the design and manufacture of high-performance digital and mixed
signal ICs, in-depth knowledge of the architecture and functioning of high-
bandwidth fiber optic communications systems, proven ASIC design methodologies
and libraries, and high-performance semiconductor manufacturing and packaging
expertise.

Design of High-Performance Digital and Mixed-Signal ICs

AMCC has developed multiple generations of products that integrate both
analog and digital elements on the same chip, while balancing the difficult
trade-offs of speed, power and timing inherent in high-speed applications.
AMCC was one of the first companies to embed analog PLLs in bipolar chips with
digital logic for high-speed data transmission and receiver applications.
Since the introduction of AMCC's first on-chip clock recovery and clock
synthesis products in 1993 (the S3005/S3006 chip set), the Company has refined
these key circuits and has successfully integrated multiple analog functions
and multiple channels on the same chip. For example, the Company has developed
a quad transceiver with a PLL clock recovery and PLL clock multiplier. The
mixing of digital and analog signals poses difficult challenges for IC
designers, particularly at high frequencies. The Company has built significant
expertise in mixed-signal IC designs through the development of multiple
generations of products. Through the acquisition of Cimaron Communications,
the Company added VLSI digital design and systems expertise. AMCC will
continue to apply these competencies in the development of increasingly
complex digital layer products. AMCC believes it can leverage these skills
into the development of high gate count digital chips with integrated complex
analog and high frequency logic.

Systems and Architecture Expertise

AMCC believes that its systems architects, design engineers and technical
marketing and applications engineers have a thorough understanding of the
fiber optic communications systems for which the Company designs and builds
ASSPs. The Company substantially expanded this expertise into higher layers of
communication systems with the acquisition of Cimaron. Using this systems
expertise, AMCC develops semiconductor devices to meet OEMs' high-bandwidth
systems requirements. By understanding the systems into which its products are
designed, the Company believes that it is better able to anticipate and
develop optimal solutions for the various cost, power and performance trade-
offs faced by its customers. AMCC believes that its systems knowledge also
enables the Company to develop more comprehensive, interoperable solutions.
This allows AMCC to develop boards with multiple products that are a more
substantial part of the customers system, enabling faster time to integration
into their products.

Process Technology

AMCC utilizes its own internal wafer fabrication facility and has developed
and produced multiple generations of cost-effective, high-performance bipolar
and BiCMOS processes. The proven internal silicon-based process technologies
employed by the Company have not required the highly capital-intensive
facilities needed by certain advanced microprocessor, memory or CMOS ASIC
suppliers. Additionally, the Company has obtained access to advanced CMOS and
SiGe BiCMOS processes through foundry relationships. The Company believes that
through the use of internal and external process technologies, the Company is
able to provide an optimal mix of cost and performance for the targeted
application.

Packaging

AMCC has substantial experience in the development and use of plastic and
ceramic packages for high-performance applications. The selection of the
optimal package solution is a vital element of the delivery of high-
performance products, and involves balancing cost, size, thermal management
and technical performance. AMCC's products are designed to reduce power
dissipation and die size to enable the use of industry standard packages. AMCC
employs a wide variety of package types, and is currently designing products
using ball grid arrays, tape ball grid arrays and multi-chip modules with pin
counts in excess of 200 pins. The Company's experience with a variety of
packages is one of the factors that enables it to provide optimal high-
performance IC solutions to its customers.

7

Research and Development

AMCC's research and development expertise and efforts are focused on the
development of high-performance analog, digital and mixed-signal ASSPs for
fiber optic communications applications. The Company also develops silicon
wafer fabrication processes and design methodologies that are optimized for
these applications.

Product Development

The Company's product development is focused on building high-performance
high gate count digital design expertise and analog-intensive design expertise
that is incorporated into well-documented blocks that can be reused for
multiple products. The Company has, and continues to make, significant
investments in advanced CAD tools to leverage its design engineering staff,
reduce design cycle time and increase first-time design correctness. The
Company's product development is driven by the imperatives of reducing design
cycle time, increasing first-time design correctness, adhering to disciplined,
well documented design processes and continuing to be responsive to customer
needs. The Company is also developing high-performance packages for its
products in collaboration with its packaging suppliers and its customers.

Process Development

The Company's process development is focused on enhancing its current
bipolar processes and developing new processes optimized for high-performance
digital and mixed-signal communications applications. AMCC's process engineers
are also involved with the selection and management of the Company's
relationships with outside foundries to provide the advanced CMOS and SiGe
BiCMOS processes required by certain of AMCC's products. A failure by the
Company to improve its existing process technologies or obtain access to new
process technologies from external foundries in a timely or affordable manner
could adversely affect the Company's business, financial condition and
operating results.

The Company's research and development expenses in fiscal years 1997, 1998,
1999 were $7.9, $13.3 and $22.5 million, respectively, which were 13.7%, 17.3%
and 21.4%, respectively, of revenues for such periods. The Company has 119
employees engaged in engineering and product development related activities.

Manufacturing

Wafer Fabrication

AMCC manufactures certain of its products at its four-inch wafer fabrication
facility in San Diego, California in an 8,200 square foot clean room. The
Company believes that its wafer fabrication facility has competitive yields,
cycle times and costs, produces large die at acceptable yields and operates on
a flexible basis of multiple products and variable lot sizes. However, there
can be no assurance that the Company will achieve or obtain acceptable
manufacturing yield levels in the future. The Company is currently running
several different bipolar and BiCMOS processes in this facility.

The Company is exploring alternatives for the expansion of its manufacturing
capacity which would likely occur after fiscal year 2000, including expanding
its current 49 wafer fabrication facility, building a new wafer fabrication
facility, purchasing a wafer fabrication facility and entering into strategic
relationships to obtain additional capacity. Any of these alternatives could
require a significant investment by the Company including an investment in
excess of $80.0 million if the Company chose to or was required to build a new
wafer fabrication facility. There can be no assurance that any of the
alternatives for expansion of its manufacturing capacity will be available on
a timely basis, or that the Company will be able to manage its growth and
effectively integrate its proposed expansion into its current operations.

AMCC currently utilizes four outside foundries, AMI Semiconductor, IBM,
Kawasaki CSI Japan and Taiwan Semiconductor Manufacturing Corporation for the
production of products designed on CMOS processes.

8

Additionally, AMCC is developing new products on IBM's SiGe BiCMOS processes.
The Company does not plan to fabricate its own CMOS wafers. The Company
generally does not have long-term wafer supply agreements with its other
outside foundries that guarantee wafer or product quantities, prices or
delivery lead times. There are certain risks associated with the Company's
dependence upon external foundries for certain of its products, including
reduced control over delivery schedules, quality assurance, manufacturing
yields and costs, the potential lack of adequate capacity during periods of
excess demand, limited warranties on wafers or products supplied to the
Company, increases in prices and potential misappropriation of the Company's
intellectual property.

Components and Raw Materials

AMCC purchases all of its "raw" silicon wafers from Wacker Siltronic
Corporation. While most silicon wafers now being supplied to the semiconductor
industry are larger than four inches, AMCC believes that Wacker Siltronic will
continue to supply AMCC's needs for the foreseeable future. AMCC also carries
a significant inventory of raw wafers to cushion any interruption in supply.
AMCC purchases its ceramic packages from Kyocera America and NTK Ceramics and
its plastic packaging from Amkor and ASAT.

Assembly and Test

The Company assembles prototypes and modest production volumes of specific
products in its internal assembly facility in San Diego, California. Most of
the Company's production assembly, however, is performed by multiple assembly
subcontractors located in the Far East, Europe and the United States.
Following assembly, the packaged units are returned to the Company for burn-in
(in some cases), final testing and marking prior to shipment to customers.
From time to time, some testing is performed by subcontractors.

Sales and Marketing

The Company sells its products principally through a direct sales
organization consisting of a network of independent manufacturers'
representatives in specified territories that work under the direction of the
Company's direct sales force and distributors.

The Company has a total of 17 direct sales personnel and field applications
engineers. The direct sales force is technically trained and is supported by
applications engineers in the field as well as applications and design
engineers at the Company's headquarters. The Company believes that this
"engineering-intensive" relationship with its customers results in strong,
long-term customer relationships beneficial to both the Company and its
customers. The Company augments this strategic account sales approach with
domestic and foreign distributors, which service primarily smaller accounts
purchasing ASSPs.

In North America, the Company's direct sales effort is supported by 18
independent manufacturers' representatives and one distributor. The Company
sells its products through 11 distributors and 2 independent manufacturers'
representatives in Europe and 8 distributors throughout the rest of the world.
During the years ended March 31, 1997, 1998, and 1999, 20%, 21% and 20%,
respectively, of net revenues were from Nortel. In 1998 and 1999, Insight
Electronics, the Company's domestic distributor, accounted for 11% and 13% of
net revenues. Additionally, in 1999, Raytheon Systems Co. accounted for 16% of
net revenues. No other customer accounted for more than 10% of revenues in any
period. In fiscal 1997, 1998 and 1999, approximately 21%, 23% and 24% of the
Company's revenues were derived from sales to customers located outside of
North America.

The Company's sales headquarters is located in San Diego, California. The
Company maintains sales offices in Burlington and Andover, Massachusetts;
Raleigh, North Carolina; Plano, Texas; San Jose, California; Munich, Germany;
Milan, Italy, Tokyo, Japan; and Cheshire, United Kingdom.

Backlog

The Company's sales are made primarily pursuant to standard purchase orders
for delivery of products. Quantities of the Company's products to be delivered
and delivery schedules are frequently revised to reflect changes in customer
needs, and customer orders can be canceled or rescheduled without significant
penalty to the customer. For these reasons, the Company's backlog as of any
particular date is not representative of actual sales for any succeeding
period, and the Company therefore believes that backlog is not a good
indicator of future revenue. The Company's backlog for products requested to
be shipped and non-recurring engineering services to be completed in the next
six months was $38.2 million on March 31, 1999, compared to $30.1 million on
March 31, 1998. Included in backlog at March 31, 1999 is the $9.3 million
balance of an order received from Raytheon Systems Co. related to an end-of-
life buy for integrated circuits used in its high speed radar systems.

Proprietary Rights

The Company relies in part on patents to protect its intellectual property.
The Company has been issued 14 patents in the United States and one patent in
Canada, which patents principally cover certain aspects of the design and
architecture of the Company's IC products and have expiration dates ranging
from 2004 to 2015. In addition, the Company has 19 patent applications pending
in the United States Patent and Trademark Office (the "PTO"). There can be no
assurance that the Company's pending patent applications or any future
applications will be approved, or that any issued patents will provide the
Company with competitive advantages or will not be challenged by third parties
or that if challenged, will be found to be valid or enforceable, or that the
patents of others will not have an adverse effect on the Company's ability to
do business. Furthermore, there can be no assurance that others will not
independently develop similar products or processes, duplicate the Company's
products or processes or design around any patents that may be issued to the
Company.

To protect its intellectual property, the Company also relies on a
combination of mask work protection under the Federal Semiconductor Chip
Protection Act of 1984, trademarks, copyrights, trade secret laws, employee
and third-party nondisclosure agreements and licensing arrangements. A mask
work refers to the intangible information content of the set of masks or mask
databases used to make a semiconductor chip product. Despite these efforts,
there can be no assurance that others will not independently develop
substantially equivalent intellectual property or otherwise gain access to the
Company's trade secrets or intellectual property, or disclose such
intellectual property or trade secrets, or that the Company can meaningfully
protect its intellectual property. A failure by the Company to meaningfully
protect its intellectual property could have a material adverse effect on the
Company's business, financial condition and operating results.

As a general matter, the semiconductor industry is characterized by
substantial litigation regarding patent and other intellectual property
rights. The Company in the past has been and in the future may be notified
that it may be infringing the intellectual property rights of third parties.
The Company has certain indemnification obligations to customers with respect
to the infringement of third party intellectual property rights by its
products. There can be no assurance that infringement claims by third parties
or claims for indemnification by customers or end users of the Company's
products resulting from infringement claims will not be asserted in the future
or that such assertions, if proven to be true, will not materially adversely
affect the Company's business, financial condition or operating results. On
July 31, 1998, the Lemelson Medical, Education & Research Foundation Limited
Partnership filed a lawsuit in the U.S. District Court for the District of
Arizona against 26 companies, including AMCC, engaged in the manufacture
and/or sale of IC products. The complaint alleges infringement by the
defendants of certain U.S. patents held by the Lemelson Partnership relating
to certain semiconductor manufacturing processes. On November 25, 1998, the
Company was served a summons pursuant to this lawsuit. The complaint seeks,
among other things, injunctive relief and unspecified treble damages.
Previously, the Lemelson Partnership has offered the Company a license under
the Lemelson patents. Management is monitoring this matter and, although the
ultimate outcome of this matter is not currently determinable, The Company
believes, based in part on the licensing terms previously offered by the
Lemelson Partnership, that the resolution of this matter will not have a
material adverse effect on the financial position or liquidity; however, there
can be

10

no assurance that the ultimate resolution of this matter will not have a
material adverse effect on the results of operations for any quarter.
Furthermore, there can be no assurance that the Company would prevail in any
such litigation. In the event of any adverse ruling in any such matter, the
Company could be required to pay substantial damages, which could include
treble damages, cease the manufacturing, use and sale of infringing products,
discontinue the use of certain processes or obtain a license under the
intellectual property rights of the third-party claiming infringement. There
can be no assurance, however, that a license would be available on reasonable
terms or at all. Any limitations on the Company's ability to market its
products, any delays and costs associated with redesigning its products or
payments of license fees to third parties or any failure by the Company to
develop or license a substitute technology on commercially reasonable terms
could have a material adverse effect on the Company's business, financial
condition and operating results.

Competition

The semiconductor market, particularly the high-performance semiconductor
market, is highly competitive and subject to rapid technological change, price
erosion and heightened international competition. The communications, ATE and
high-speed computing industries are also becoming intensely competitive due in
part to deregulation and heightened international competition. The ability of
the Company to compete successfully in its markets depends on a number of
factors, including product performance, success in designing and
subcontracting the manufacture of new products that implement new
technologies, product quality, reliability, price, the efficiency of
production, design wins for its IC products, ramp up of production of the
Company's products for particular system manufacturers, end-user acceptance of
the system manufacturers' products, market acceptance of competitors' products
and general economic conditions. In addition, the Company's competitors may
offer enhancements to existing products, or offer new products based on new
technologies, industry standards or customer requirements, that are available
to customers on a more timely basis than comparable products from the Company
or that have the potential to replace or provide lower cost alternatives to
the Company's products. The introduction of such enhancements or new products
by the Company's competitors could render the Company's existing and future
products obsolete or unmarketable. Furthermore, once a customer has designed a
supplier's product into its system, the customer is extremely reluctant to
change its supply source due to the significant costs associated with
qualifying a new supplier. Finally, the Company expects that certain of its
competitors and other semiconductor companies may seek to develop and
introduce products that integrate the functions performed by the Company's IC
products on a single chip, thus eliminating the need for the Company's
products. Each of these factors could have a material adverse effect on the
Company's business, financial condition and results of operations.

In the communications markets, the Company competes primarily against
companies such as Analog Devices, Conextant, Giga, Hewlett-Packard, Lucent,
Maxim, PMC-Sierra, Philips, Sony, Texas Instruments, TriQuint and Vitesse. In
certain circumstances, most notably with respect to ASICs supplied to Nortel,
AMCC's customers or potential customers have internal IC manufacturing
capability, and this internal source is an alternative available to the
customer. In the ATE market, the Company competes primarily against Vitesse
and silicon ECL and BiCMOS products offered principally by semiconductor
manufacturers such as Analog Devices, Lucent Technologies and Maxim. In the
high-speed computing market, the Company competes primarily against companies
such as Chrontel, Cypress, ICS, PLX and Tundra. Many of these companies and
potential new competitors have significantly greater financial, technical,
manufacturing and marketing resources than the Company. In addition, in lower-
frequency applications, the Company faces increasing competition from other
CMOS-based products, particularly as the performance of such products
continues to improve. There can be no assurance that the Company will be able
to develop new products to compete with new technologies on a timely basis or
in a cost-effective manner. Any failure by the Company to compete successfully
in its target markets, particularly in the communications markets, would have
a material adverse effect on the Company's business, financial condition and
results of operations.

11

Environmental Matters

The Company is subject to a variety of federal, state and local governmental
regulations related to the use, storage, discharge and disposal of toxic,
volatile or otherwise hazardous chemicals used in its manufacturing process.
Any failure to comply with present or future regulations could result in the
imposition of fines on the Company, the suspension of production or a
cessation of operations. In addition, such regulations could restrict the
Company's ability to expand its facilities at its present location or
construct or operate its planned wafer fabrication facility or could require
the Company to acquire costly equipment or incur other significant expenses to
comply with environmental regulations or clean up prior discharges. In this
regard, since 1993 the Company has been named as a potentially responsible
party ("PRP") along with a large number of other companies that used Omega
Chemical Corporation ("Omega") in Whittier, California to handle and dispose
of certain hazardous waste material. The Company is a member of a large group
of PRPs that has agreed to fund certain remediation efforts at the Omega site,
which efforts are ongoing. To date, the Company's payment obligations with
respect to such funding efforts have not been material, and the Company
believes that its future obligations to fund such efforts will not have a
material adverse effect on its business, financial condition or operating
results. Although the Company believes that it is currently in material
compliance with applicable environmental laws and regulations, there can be no
assurance that the Company is or will be in material compliance with such laws
or regulations or that the Company's future obligations to fund any
remediation efforts, including those at the Omega site, will not have a
material adverse effect on the Company's business, financial condition or
operating results.

Employees

As of March 31, 1999, the Company had 361 full-time employees: 29 in
administration, 119 in engineering and product development, 155 in operations
and 58 in marketing and sales. The Company's ability to attract and retain
qualified personnel is essential to its continued success. None of the
Company's employees is represented by a collective bargaining agreement, nor
has the Company ever experienced any work stoppage. The Company believes its
employee relations are good. Loss of the services of, or failure to recruit,
key design engineers or other technical and management personnel could be
significantly detrimental to the Company's product and process development
programs or otherwise have a material adverse effect on the Company's
business, financial condition, and operating results.

Factors That May Affect Future Results

Our operating results may fluctuate because of many factors, many of which
are beyond our control

If our operating results are below the expectations of public market
analysts or investors, then the market price of our common stock could be
materially and adversely affected.

Some of the factors that affect our quarterly and annual results, but which
are difficult to control or predict are:

. the rescheduling or cancellation of orders by customers;

. fluctuations in the timing and amount of customer requests for product
shipments;

. fluctuations in manufacturing output, yields and inventory levels;

. changes in the mix of products that our customers buy;

. our ability to introduce new products and technologies on a timely
basis;

. the announcement or introduction of products and technologies by our
competitors;

. the availability of external foundry capacity, purchased parts and raw
materials;

. competitive pressures on selling prices;

. the amounts and timing of costs associated with warranties and product
returns;

. the amounts and timing of investments in research and development;

. market acceptance of our products and of our customers' products;

. the timing of depreciation and other expenses that we expect to incur in
connection with any required expansion of our manufacturing capacity;

. costs associated with compliance with applicable environmental
regulations or remediation;

. costs associated with future litigation, if any, including without
limitation, litigation or settlements relating to the use or ownership
of intellectual property;

. general semiconductor industry conditions; and

. general economic conditions.

Our expense levels are relatively fixed and are based, in part, on our
expectations of future revenues. We are continuing to increase our operating
expenses for personnel and new product development. However, we

14

have a limited ability to reduce expenses quickly in response to any revenue
shortfalls. Consequently, our business, financial condition and operating
results would be adversely affected if we do not achieve increased revenues.
We can have revenue shortfalls for a variety of reasons, including:

. significant pricing pressures that occur because of declines in average
selling prices over the life of a product;

. sudden shortages of raw materials or production capacity constraints
that lead producers to allocate available supplies or capacity to
customers with resources greater than us and, in turn, interrupt our
ability to meet our production obligations;

. fabrication, test or assembly capacity constraints for internally
manufactured devices which interrupt our ability to meet our production
obligations; and

. the rescheduling or cancellation of customer orders.

In addition, our business is characterized by short-term orders and shipment
schedules, and customer orders typically can be canceled or rescheduled
without significant penalty to the customer. Due to the absence of substantial
noncancellable backlog, we typically plan our production and inventory levels
based on internal forecasts of customer demand, which are highly unpredictable
and can fluctuate substantially. In addition, from time to time, in response
to anticipated long lead times to obtain inventory and materials from our
outside foundries, we may order materials in advance of anticipated customer
demand, which might result in excess inventory levels or unanticipated
inventory write-downs if expected orders fail to materialize, or other factors
render the customer's products less marketable. Furthermore, we currently
anticipate that an increasing portion of our revenues in future periods will
be derived from sales of application-specific standard products ("ASSPs"), as
compared to application-specific integrated circuits ("ASICs"). Customer
orders for ASSPs typically have shorter lead times than orders for ASICs,
which may make it increasingly difficult for us to predict revenues and
inventory levels and adjust production appropriately in future periods. If we
are unable to plan inventory and production levels effectively, our financial
condition and operating results could be materially adversely affected.

One example of the volatility of our results is that we experienced revenue
fluctuations and incurred net losses in fiscal 1995 and 1996. These revenue
fluctuations and net losses were caused by the termination of a relationship
with a strategic foundry partner, decreased orders from two major customers,
charges associated with a reduction in the company's workforce and charges for
excess inventory. Accordingly, we believe that period-to-period comparisons of
operating results should not be relied upon as an indication of future
performance. In addition, the results of any quarterly period are not
indicative of results to be expected for a full fiscal year.

Our operating results depend substantially on our manufacturing yields, which
may not meet expectations.

AMCC Fabrication

We manufacture most of our semiconductors at our San Diego 49 wafer
fabrication facility. Our yields can decline whenever a substantial percentage
of wafers must be rejected or a significant number of die on each wafer are
nonfunctional. Such declines can be caused by many factors over which we have
little or no control, including minute levels of contaminants in the
manufacturing environment, design issues, defects in masks used to print
circuits on a wafer and difficulties in the fabrication process.
Unfortunately, the ongoing expansion of the manufacturing capacity of our
existing wafer fabrication facility could increase the risk of contaminants in
the facility. In addition, many of these problems are difficult to diagnose,
time consuming and expensive to remedy and can result in shipment delays.

Because the majority of our costs of manufacturing are relatively fixed,
maintenance of the number of shippable die per wafer is critical to our
results of operations. Yield decreases can result in substantially higher unit
costs and may result in reduced gross profit and net income. In the past we
experienced yield problems in connection with the manufacture of our products.
We estimate yields per wafer in order to estimate the value of inventory. If
yields are materially different than projected, work-in-process inventory may
need to be revalued.

15

We have in the past and may in the future from time to time take inventory
write-downs as a result of decreases in manufacturing yields. We may suffer
periodic yield problems in connection with new or existing products or in
connection with the commencement of production in our proposed new
manufacturing facility or the transfer of our operations to this facility.

Fabrication by Third Parties

Semiconductor manufacturing yields are a function both of product design and
process technology. When our products are manufactured by an outside foundry,
the process technology is typically proprietary to the manufacturer. Since low
yields may result from either design or process technology failures, yield
problems may not be effectively determined or resolved until an actual product
exists that can be analyzed and tested to identify process sensitivities
relating to the design rules that are used. As a result, yield problems may
not be identified until well into the production process, and resolution of
yield problems may require cooperation between ourselves and our manufacturer.
In some cases this risk could be compounded by the offshore location of
certain of our manufacturers, increasing the effort and time required to
identify, communicate and resolve manufacturing yield problems.

If we develop relationships with additional outside foundries, yields could
be adversely affected due to difficulties associated with adapting our
technology and product design to the proprietary process technology and design
rules of the new foundries. Because of our limited access to wafer fabrication
capacity from outside foundries for certain products, any decrease in
manufacturing yields of such products could result in an increase in our per
unit costs for such products and force us to allocate available product supply
among customers, which could potentially adversely impact customer
relationships as well as revenues and gross margin. Our outside foundries may
not achieve or maintain acceptable manufacturing yields in the future.
Furthermore, we also face the risk of product recalls resulting from design or
manufacturing defects which are not discovered during the manufacturing and
testing process.

Our business strategy is based on increasing dependence on the WAN and LAN
communications markets.

An important part of our strategy is to continue our focus on the WAN market
and to leverage our technology and expertise to penetrate further the LAN
market for high-speed ICs. If we are unable to penetrate these markets
further, our short and long term business will suffer. In the short term, we
may experience reduced revenues. In the long term, our revenues could stop
growing and may decline. We anticipate that sales to our other traditional
markets will grow more slowly or not at all and, in some instances, as in the
case of military markets, may decrease over time.

The communications markets are characterized by:

. extreme price competition;

. rapid technological change;

. industry standards that are continually evolving; and

. in many cases, short product life cycles.

These markets frequently undergo transitions in which products rapidly
incorporate new features and performance standards on an industry-wide basis.
If our products are unable to support the new features or performance levels
required by OEMs in these markets, we would be likely to lose business from an
existing or potential customer and, moreover, would not have the opportunity
to compete for new design wins until the next product transition occurs. If we
fail to develop products with required features or performance standards for
the telecommunications or data communications markets, or if we experience a
delay as short as a few months in bringing a new product to market, or if our
telecommunications or data communications customers fail to achieve market
acceptance of their products, our revenues could be significantly reduced for
a substantial period.

16

A significant portion of our revenues in recent periods has been, and is
expected to continue to be, derived from sales of products based on the
Synchronous Optical Network, or SONET, and Synchronous Digital Hierarchy, or
SDH, transmission standards and the Asynchronous Transfer Mode, or ATM,
transmission standard. If the communications market evolves to new standards,
we may not be able to successfully design and manufacture new products that
address the needs of our customers or gain substantial market acceptance.
Although we have developed products for the Gigabit Ethernet and Fibre Channel
communications standards, volume sales of these products are modest, and we
may not be successful in addressing the market opportunities for products
based on these standards.

Our business could be adversely affected if we do not adequately address the
risks associated with our recent acquisition of Cimaron Communications
Corporation.

In March 1999, we completed the acquisition of Cimaron Communications
Corporation. This transaction is accompanied by a number of risks, including:

. the difficulty of assimilating the operations and personnel of Cimaron;

. the potential disruption of AMCC's and Cimaron's ongoing business and
distraction of management;

. possible unanticipated expenses related to technology integration;

. the potential impairment of relationships with employees and customers
as a result of any integration of new management personnel; and

. potential unknown liabilities associated with acquired businesses.

We may not be successful in addressing these risks or any other problems
encountered in connection with the Cimaron acquisition.

In addition, the market price of our common stock could decline as a result
of the merger if:

. the integration of AMCC and Cimaron is unsuccessful;

. the combined company does not achieve the perceived benefits of the
merger as rapidly or to the extent anticipated by financial analysts;

. the effect of the merger on the combined company financial results is
not consistent with the expectations of financial analysts; or

. the Company is unsuccessful in the management of Cimaron employees who
are geographically distant from the headquarters, but engaged in
developing technology and products that are vital for future revenues.

We have accounted for the merger under the pooling-of-interests accounting
method and financial reporting rules. To qualify the merger as a pooling-of-
interests for accounting purposes, AMCC and Cimaron and their respective
affiliates must meet the criteria for pooling-of-interests accounting
established in opinions published by the Accounting Principles Board and
interpreted by the Financial Accounting Standards Board and the Commission.
These opinions are complex, and the interpretation of them is subject to
change. However, the availability of pooling-of-interests accounting treatment
for the merger depends in part, upon circumstances and events occurring after
the effective time. For example, there must be no significant changes in the
business of the combined company, including significant dispositions of
assets, for a period of two years following the effective time. The failure of
the merger to qualify for pooling-of-interests accounting treatment for
financial reporting purposes for any reason would materially and adversely
affect our reported earnings and likely, the price of our common stock.

17

Our business strategy is also based on increasing dependence on application-
specific standard products.

We have under development a number of ASSPs for the communications markets,
from which we expect to derive an increasing portion our future revenues.
However, we have a limited operating history in selling ASSPs, particularly to
customers in the communications markets. In addition, our relationships with
certain customers in these markets have only been established recently. Our
future success in selling ASSPs, and in particular, selling ASSPs to customers
in the telecommunications and data communications markets, will depend in
large part on whether our ASSPs are developed on a timely basis and whether
such products achieve market acceptance among new and existing customers, and
on the timing of the commencement of volume production of products
incorporating our ASSPs, if at all. We have in the past encountered
difficulties in introducing new products in accordance with customers'
delivery schedules and initial expectations. We may encounter similar
difficulties in the future, and we may not be able to develop and introduce
ASSPs in a timely manner so as to meet customer demands.

We currently depend on the automated test equipment market, and that market
has recently experienced declines in demand.

We have historically derived significant revenues from product sales to
customers in the Automated Test Equipment, or ATE, market and currently
anticipate that we will continue to derive revenues from sales to customers in
this market in the near term. During the past year, customers in the ATE
market have experienced decreased demand due primarily to slower growth in the
semiconductor industry and economic turmoil in Asia. Accordingly, our net
revenues in the ATE market has declined for four consecutive quarters as of
March 31, 1999, and it is possible that our revenue from the ATE market may
decline further.

We depend on the high-speed computing market, but we believe that the average
selling prices of our IC products for the high-speed computing market will
decline in future periods and that our gross margin on sales of such products
may also decline in future periods.

The market for high-speed computing IC products is subject to extreme price
competition, and we may not be able to reduce the costs of manufacturing high-
speed computing IC products in response to declining average selling prices.
Even if we successfully utilize new processes or technologies to reduce the
manufacturing costs of our high-speed computing products in a timely manner,
our customers in the high-speed computing market may not purchase these
products.

Furthermore, we expect that certain competitors may seek to develop and
introduce products that integrate the functions performed by our high-speed
computing IC products on a single chip. In addition, one or more of our
customers may choose to utilize discrete components to perform the functions
served by our high-speed computing IC products or may use their own design and
fabrication facilities to create a similar product. In either case, the need
for high-speed computing customers to purchase our IC products could be
eliminated.

Our markets are subject to rapid technological change, so our success depends
heavily on our ability to develop and introduce new products.

The markets for our products are characterized by:

. rapidly changing technologies;

. evolving and competing industry standards;

. short product life cycles;

. changing customer needs;

. emerging competition;

. frequent new product introductions and enhancements;

18

. increased integration with other functions; and

. rapid product obsolescence.

To develop new products for the communications markets, we must develop,
gain access to and use leading technologies in a cost-effective and timely
manner and continue to develop technical and design expertise. In addition, we
must have our products designed into our customers' future products and
maintain close working relationships with key customers in order to develop
new products, particularly ASSPs, that meet customers' changing needs. We also
must respond to changing industry standards, trends towards increased
integration and other technological changes on a timely and cost-effective
basis. Furthermore, if we fail to achieve design wins with key customers our
business will be significantly hurt because once a customer has designed a
supplier's product into its system, the customer typically is extremely
reluctant to change its supply source due to significant costs associated with
qualifying a new supplier.

Products for communications applications, as well as for high-speed
computing applications, are based on industry standards that are continually
evolving. Our ability to compete in the future will depend on our ability to
identify and ensure compliance with these evolving industry standards. The
emergence of new industry standards could render our products incompatible
with products developed by major systems manufacturers. As a result, we could
be required to invest significant time and effort and to incur significant
expense to redesign our products to ensure compliance with relevant standards.
If our products are not in compliance with prevailing industry standards for a
significant period of time, we could miss opportunities to achieve crucial
design wins. We may not be successful in developing or using new technologies
or in developing new products or product enhancements that achieve market
acceptance. Our pursuit of necessary technological advances may require
substantial time and expense.

The markets in which we compete are highly competitive and subject to rapid
technological change, price erosion and heightened international competition.

The communications, ATE and high-speed computing industries are intensely
competitive. We believe that the principal factors of competition in our
markets are price, product performance, product quality and time-to-market.
Our ability to compete successfully in our markets depends on a number of
factors, including:

. success in designing and subcontracting the manufacture of new products
that implement new technologies;

. product quality;

. reliability;

. price;

. the efficiency of production;

. design wins for our IC products;

. expansion of production of our products for particular systems
manufacturers;

. end-user acceptance of the systems manufacturers' products;

. market acceptance of competitors' products; and

. general economic conditions.

In addition, our competitors may offer enhancements to existing products or
offer new products based on new technologies, industry standards or customer
requirements that are available to customers on a more timely basis than
comparable products from us or that have the potential to replace or provide
lower-cost alternatives to our products. The introduction of enhancements or
new products by our competitors could render our existing and future products
obsolete or unmarketable. In addition, we expect that certain of our
competitors and other semiconductor companies may seek to develop and
introduce products that integrate the functions performed by our IC products
on a single chip, thus eliminating the need for our products.

19

In the communications markets, we compete primarily against Giga, Hewlett-
Packard, Lucent, Maxim, Philips, Sony, Texas Instruments, Conexant, TriQuint
and Vitesse. Some of these companies use gallium arsenide ("GaAs") process
technologies for certain products. In certain circumstances, most notably with
respect to ASICs supplied to Nortel, our customers or potential customers have
internal IC manufacturing capabilities. In the ATE market, our products
compete primarily against GaAs based products offered by Vitesse and silicon
ECL and BiCMOS products offered principally by semiconductor manufacturers
such as Analog Devices, Lucent Technologies and Maxim. In the high-speed
computing market, we compete primarily against Chrontel, Cypress, ICS, PLX and
Tundra. Many of these companies and potential new competitors have
significantly greater financial, technical, manufacturing and marketing
resources than we do.

If we are not successful in expanding our manufacturing capacity, on time, we
may face serious capacity constraints.

We currently manufacture a majority of our IC products at our four-inch
wafer fabrication facility located in San Diego, California. We believe that
we will be able to satisfy our production needs from this fabrication facility
through fiscal 2001, although this date may vary depending on, among other
things, our rate of growth. However, if we cannot expand our capacity on a
timely basis, we could experience significant capacity constraints that could
render us unable to meet customer demand or force us to spend more to make
wafers to meet demand. We will be required to hire, train and manage
additional production personnel in order to increase production capacity as
scheduled.

The Company is exploring alternatives for the expansion of its manufacturing
capacity which would likely occur after fiscal year 2000, including expanding
its current 4" wafer fabrication facility, building a new wafer fabrication
facility, purchasing a wafer fabrication facility and entering into strategic
relationships to obtain additional capacity. Any of these alternatives could
require a significant investment by the Company including an investment in
excess of $80.0 million if the Company chose to or was required to build a new
wafer fabrication facility. There can be no assurance that any of the
alternatives for expansion of its manufacturing capacity will be available on
a timely basis, the Company will be able to manage its growth or effectively
integrate its proposed expansion into its current operations.

The cost of any investment the Company may have to make in expanding its
manufacturing capacity is expected to be funded through a combination of
available cash, cash equivalents and short-term investments, cash from
operations and additional debt, lease or equity financing. We may not be able
to obtain the additional financing necessary to fund the expansion of our
manufacturing capacity. Our existing wafer fabrication facility is, and the
potential new wafer fabrication facility may be, located in California and
these facilities may be subject to natural disasters such as earthquakes or
floods. In addition, the depreciation and other expenses that we will incur in
connection with the expansion of our manufacturing capacity may adversely
affect our gross margin in any future fiscal period.

Expanding our current 4" wafer fabrication facility, building a new wafer
fabrication facility or purchasing a wafer fabrication facility entails
significant risks, including:

. shortages of materials and skilled labor;

. unforeseen environmental or engineering problems;

. work stoppages;

. weather interferences; and

. unanticipated cost increases.

Any one of these risks could have a material adverse effect on the building,
equipping and production start-up of the new facility or the expansion of the
existing facility. In addition, unexpected changes or concessions required by
local, state or federal regulatory agencies with respect to necessary
licenses, land use permits, site

20

approvals and building permits could involve significant additional costs and
delay the scheduled opening of the expansion or new facility and could reduce
our anticipated revenues. Also, the timing of commencement of operation of
expansion or new facility will depend upon the availability, timely delivery
and successful installation and testing of the necessary process equipment. As
a result of the foregoing and other factors, the expansion or new facility may
not be completed and in volume production within its current budget or within
the period currently scheduled. Furthermore, we may be unable to achieve
adequate manufacturing yields in expansion or new facility in a timely manner,
and our revenues may not increase commensurate with the anticipated increase
in manufacturing capacity associated with the expansion or new facility. In
addition, in the future, we may be required for competitive reasons to make
capital investments in the existing wafer fabrication facility or to
accelerate the timing of the construction of a new wafer fabrication facility
in order to expedite the manufacture of products based on more advanced
manufacturing processes.

The successful operation of a potential new 6" wafer fabrication facility,
if completed, as well as our overall production operations, will also be
subject to numerous risks. We have no prior experience with the operation of
the equipment or the processes involved in producing finished six-inch wafers,
which differ significantly from those involved in the production of four-inch
wafers. We will be required to hire, train and manage production personnel in
order to effectively operate the new facility. We do not have sufficient
excess production capacity at our existing San Diego facility to fully offset
any failure of the proposed new wafer fabrication facility to meet planned
production goals. We may transfer current San Diego manufacturing operations
into the proposed new wafer fabrication facility subsequent to its completion.
Should this transfer occur, we may experience delays in completing product
testing and documentation required by customers to qualify or requalify our
products from this facility. We will also have to effectively coordinate and
manage two manufacturing facilities to successfully meet overall production
goals. We have no experience in coordinating and managing production
facilities that are located at different sites or in the transfer of
manufacturing operations from one facility to another. As a result of these
and other factors, our failure to successfully operate the proposed new wafer
fabrication facility, to successfully coordinate and manage the two sites or
to transfer our manufacturing operations could adversely affect our overall
production.

The markets for our products are characterized by rapid changes in
manufacturing process technologies; therefore, to provide competitive
products to our target markets, we must develop or otherwise gain access to
improved process technologies.

Our future success will depend, in large part, upon our ability to continue
to improve existing process technologies, to develop new process technologies
including silicon germanium, or SiGe, processes, and to adapt our process
technologies to emerging industry standards. In the future, we may be required
to transition one or more of our products to process technologies with smaller
geometries, other materials or higher speeds in order to reduce costs and/or
improve product performance. We may not be able to improve our process
technologies and develop or otherwise gain access to new process technologies,
including, but not limited to SiGe process technologies, in a timely or
affordable manner. In addition, products based on these technologies may not
achieve market acceptance.

Our dependence on third-party manufacturing and supply relationships
increases the risk that we will not have an adequate supply of products to
meet demand or that our cost of goods will be higher than expected.

We rely on outside foundries for the manufacture of certain products,
including all of our products designed on CMOS processes and all products that
we anticipate will be designed on silicon germanium processes. We generally do
not have long-term wafer supply agreements with our outside foundries that
guarantee wafer or product quantities, prices or delivery lead times. Instead,
our products that are manufactured by outside foundries are manufactured on a
purchase order basis. We expect that, for the foreseeable future, certain
products will be manufactured by a single outside foundry. Because
establishing relationships with new outside foundries takes several months,
there is no readily available alternative source of supply for these products.
A manufacturing disruption experienced by one or more of our outside foundries
would impact the production of certain of our

21

products for a substantial period of time. Furthermore, the transition to the
next generation of manufacturing technologies at one or more of our outside
foundries could be unsuccessful or delayed.

There are additional risks associated with our dependence upon third-party
manufacturers for certain products. These include, but are not limited to:

. reduced control over delivery schedules and quality;

. risks of inadequate manufacturing yields and excessive costs;

. the potential lack of adequate capacity during periods of excess demand;

. limited warranties on wafers or products supplied to us;

. potential increases in prices; and

. potential misappropriation of our intellectual property.

With respect to certain of our products, we depend upon external foundries
to produce wafers and, in some cases, finished products of acceptable quality,
to deliver those wafers and products to us on a timely basis and to allocate
to us a portion of their manufacturing capacity sufficient to meet our needs.
On occasion, we have experienced difficulties with our suppliers failing to
produce goods of sufficient quality or quantity or failing to meet delivery
deadlines. Our wafer and product requirements typically represent a very small
portion of the total production of these external foundries. As a result, we
are subject to the risk that a producer will cease production on an older or
lower-volume process that is used to produce our parts. Additionally, we
cannot be certain our external foundries will continue to devote resources to
the production of our products or continue to advance the process design
technologies on which the manufacturing of our products are based.

Certain of our products are assembled and packaged by third-party
subcontractors. We do not have long-term agreements with any of these
subcontractors. Assembly and packaging is conducted on a purchase order basis.
As a result, we cannot directly control product delivery schedules. This could
lead to product shortages or quality assurance problems that could increase
the costs of manufacturing, assembly or packaging of our products. In
addition, we may, from time to time, be required to accept price increases for
assembly or packaging services. Due to the amount of time normally required to
qualify assembly and packaging subcontractors, product shipments could be
delayed significantly if we are required to find alternative subcontractors.
In the future, we may contract with third parties for the testing of our
products. Any problems associated with the delivery, quality or cost of the
assembly, testing or packaging of our products could have a material adverse
effect on our business.

Due to an industry transition to six-inch and eight-inch wafer fabrication
facilities, there is a limited number of suppliers of the four-inch wafers
that we use to build products in our existing manufacturing facility, and we
rely on a single supplier for these wafers. Although we believe that we will
have sufficient access to four-inch wafers to support production in our
existing fabrication facility for the foreseeable future, we cannot be certain
that our current supplier will continue to supply us with four-inch wafers on
a long-term basis. Additionally, the availability of manufacturing equipment
needed for a four-inch process is limited, and certain new equipment required
for more advanced processes may not be available for a four-inch process.

Our customers are concentrated, so the loss of one or more key customers
could significantly reduce our revenues and profits.

Historically, a relatively small number of customers has accounted for a
significant portion of our revenues in any particular period. For example, our
five largest customers accounted for approximately 44%, 46%, and 59% of our
revenues in fiscal 1997, 1998, and 1999, respectively, and sales to Nortel
accounted for approximately 20%, 21%, and 20% of our revenues in each of these
periods. However, we have no long-term volume purchase commitments from any of
our major customers. We anticipate that sales of products to relatively few
customers will continue to account for a significant portion of our revenues.
A reduction, delay or cancellation of orders from one or more significant
customers or the loss of one or more key customers could

22

significantly reduce our revenues and profits. We cannot assure you that our
current customers will continue to place orders with us, that orders by
existing customers will continue at current or historical levels or that we
will be able to obtain orders from new customers.

Our strategy is based on growth, and periods of rapid growth and expansion
have placed, and could continue to place, a significant strain on our limited
personnel and other resources

To manage expanded operations effectively, we will be required to continue
to improve our operational, financial and management systems and to
successfully hire, train, motivate and manage our employees. In addition, the
integration of past and future potential acquisitions, the expansion of our
manufacturing capacity will require significant management, technical and
administrative resources. We cannot be certain that we will be able to manage
our growth or effectively integrate our planned wafer fabrication facility
into our current operations.

Our future success depends in part on the continued service of our key design
engineering, sales, marketing and executive personnel and our ability to
identify, hire and retain additional personnel.

There is intense competition for qualified personnel in the semiconductor
industry, in particular design engineers, and we may not be able to continue
to attract and train engineers or other qualified personnel necessary for the
development of our business or to replace engineers or other qualified
personnel who may leave our employ in the future. Our anticipated growth is
expected to place increased demands on our resources and will likely require
the addition of new management personnel and the development of additional
expertise by existing management personnel. Although we have entered into an
"at-will" employment agreement with David M. Rickey, the President and Chief
Executive Officer, we have not entered into fixed term employment agreements
with any of our executive officers except for one-year employment agreements
with Ram Sudireddy, Vice President, Cimaron, and Gary Martin, Vice President
and Chief Technical Officer, Cimaron. In addition, we have not obtained key-
person life insurance on any of our executive officers or key employees. Loss
of the services of, or failure to recruit, key design engineers or other
technical and management personnel could be significantly detrimental to our
product and process development programs.

We anticipate that we will need to raise additional capital in the future,
and we cannot be certain that additional debt, lease or equity financing will
be available on commercially reasonable terms or at all.

We require substantial working capital to fund our business, particularly to
finance inventories and accounts receivable and for capital expenditures. We
believe that our available cash, cash equivalents and short-term investments
and cash generated from operations, will be sufficient to meet our capital
requirements through the next 12 months, although we could be required, or
could elect, to seek to raise additional financing during this period. Our
future capital requirements will depend on many factors, including:

. the costs associated with the expansion of manufacturing operations;

. the rate of revenue growth;

. the timing and extent of spending to support research and development
programs and expansion of sales and marketing;

. the timing of introductions of new products and enhancements to existing
products; and

. market acceptance of our products.

Additionally, we may elect to acquire other businesses, which would entail
the issuance of stock and the payment of cash. We may elect to raise
additional cash to finance such transactions. We may need to raise additional
debt or equity financing in the future, primarily for purposes of financing
the acquisition of property for our proposed new wafer fabrication facility,
the construction of the proposed new wafer fabrication facility and the
purchase of equipment for the proposed new wafer fabrication facility.

23

We may not be able to protect our intellectual property adequately.

We rely in part on patents to protect our intellectual property. There can
be no assurance that our pending patent applications or any future
applications will be approved, or that any issued patents will provide us with
competitive advantages or will not be challenged by third parties, or that if
challenged, will be found to be valid or enforceable, or that the patents of
others will not have an adverse effect on our ability to do business.
Furthermore, others may independently develop similar products or processes,
duplicate our products or processes or design around any patents that may be
issued to us.

To protect our intellectual property, we also rely on the combination of
mask work protection under the Federal Semiconductor Chip Protection Act of
1984, trademarks, copyrights, trade secret laws, employee and third-party
nondisclosure agreements and licensing arrangements. Despite these efforts, we
cannot be certain that others will not independently develop substantially
equivalent intellectual property or otherwise gain access to our trade secrets
or intellectual property, or disclose such intellectual property or trade
secrets, or that we can meaningfully protect our intellectual property.

Our business, operating results and financial condition could be materially
adversely affected by litigation involving patents and proprietary rights.

As a general matter, the semiconductor industry is characterized by
substantial litigation regarding patent and other intellectual property
rights. We have, in the past and may, in the future be notified that we may be
infringing the intellectual property rights of third parties. We have certain
indemnification obligations to customers with respect to the infringement of
third-party intellectual property rights by our products. We cannot be certain
that infringement claims by third parties or claims for indemnification by
customers or end users of our products resulting from infringement claims will
not be asserted in the future or that such assertions, if proven to be true,
will not materially adversely affect our business. On July 31, 1998, the
Lemelson Medical, Education & Research Foundation Limited Partnership filed a
lawsuit in the U.S. District Court for the District of Arizona against 26
companies, including us, engaged in the manufacture and/or sale of IC
products. The complaint alleges infringement by the defendants of certain U.S.
patents held by the Lemelson Partnership relating to certain semiconductor
manufacturing processes. On November 25, 1998, we were served a summons
pursuant to this lawsuit. The complaint seeks, among other things, injunctive
relief and unspecified treble damages. Previously, the Lemelson Partnership
has offered us a license under the Lemelson patents. We are monitoring this
matter and, although the ultimate outcome of this matter is not currently
determinable, we believe, based in part on the licensing terms previously
offered by the Lemelson Partnership, that the resolution of this matter will
not have a material adverse effect on our financial position or liquidity;
however, there can be no assurance that the ultimate resolution of this matter
will not have a material adverse effect on our results of operations for any
quarter. Furthermore, there can be no assurance that we would prevail in any
such litigation.

Any litigation relating to the intellectual property rights of third
parties, including the Lemelson Patents, whether or not determined in our
favor or settled by us, would at a minimum be costly and could divert the
efforts and attention of our management and technical personnel. In the event
of any adverse ruling in any such litigation, we could be required to pay
substantial damages, cease the manufacturing, use and sale of infringing
products, discontinue the use of certain processes or obtain a license under
the intellectual property rights of the third party claiming infringement. A
license might not be available on reasonable terms or at all.

Our operating results are subject to fluctuations because we rely
substantially on foreign customers.

International sales (including sales to Canada) accounted for 40%, 42% and
41% of revenues in fiscal 1997, fiscal 1998 and fiscal 1999, respectively.
International sales may increase in future periods and may account for an
increasing portion of our revenues. As a result, an increasing portion of our
revenues may be subject to certain risks, including:

. changes in regulatory requirements;

24

. tariffs and other barriers;

. timing and availability of export licenses;

. political and economic instability;

. difficulties in accounts receivable collections;

. natural disasters;

. difficulties in staffing and managing foreign subsidiary and branch
operations;

. difficulties in managing distributors;

. difficulties in obtaining governmental approvals for communications and
other products;

. foreign currency exchange fluctuations;

. the burden of complying with a wide variety of complex foreign laws and
treaties; and

. potentially adverse tax consequences.

Although less than seven percent of our revenues were attributable to sales
in Asia during the year ended March 31, 1999, the recent economic instability
in certain Asian countries could adversely affect our business, financial
condition and operating results, particularly to the extent that this
instability impacts the sales of products manufactured by our customers. We
are also subject to the risks associated with the imposition of legislation
and regulations relating to the import or export of high technology products.
We cannot predict whether quotas, duties, taxes or other charges or
restrictions upon the importation or exportation of our products will be
implemented by the United States or other countries. Because sales of our
products have been denominated to date primarily in United States dollars,
increases in the value of the United States dollar could increase the price of
our products so that they become relatively more expensive to customers in the
local currency of a particular country, leading to a reduction in sales and
profitability in that country. Future international activity may result in
increased foreign currency denominated sales. Gains and losses on the
conversion to United States dollars of accounts receivable, accounts payable
and other monetary assets and liabilities arising from international
operations may contribute to fluctuations in our results of operations. Some
of our customer purchase orders and agreements are governed by foreign laws,
which may differ significantly from United States laws. Therefore, we may be
limited in our ability to enforce our rights under such agreements and to
collect damages, if awarded.

We could incur substantial fines or litigation costs associated with our
storage, use and disposal of hazardous materials.

We are subject to a variety of federal, state and local governmental
regulations related to the use, storage, discharge and disposal of toxic,
volatile or otherwise hazardous chemicals used in our manufacturing process.
Any failure to comply with present or future regulations could result in the
imposition of fines, the suspension of production or a cessation of
operations. In addition, these regulations could restrict our ability to
expand our facilities at the present location or construct or operate our
planned wafer fabrication facility or could require us to acquire costly
equipment or incur other significant expenses to comply with environmental
regulations or clean up prior discharges. Since 1993 we have been named as a
potentially responsible party, or PRP, along with a large number of other
companies that used Omega Chemical Corporation in Whittier, California to
handle and dispose of certain hazardous waste material. We are a member of a
large group of PRPs that has agreed to fund certain remediation efforts at the
Omega site, which efforts are ongoing. To date, our payment obligations with
respect to these funding efforts have not been material, and we believe that
our future obligations to fund these efforts will not have a material adverse
effect on our business, financial condition or operating results. Although we
believe that we are currently in material compliance with applicable
environmental laws and regulations, we cannot assure you that we are or will
be in material compliance with these laws or regulations or that our future
obligations to fund any remediation efforts, including those at the Omega
site, will not have a material adverse effect on our business.

25

Our ability to manufacture sufficient wafers to meet demand could be severely
hampered by a shortage of water.

We use significant amounts of water throughout our manufacturing process.
Previous droughts in California have resulted in restrictions being placed on
water use by manufacturers and residents in California. In the event of future
drought, reductions in water use may be mandated generally, and it is unclear
how such reductions will be allocated among California's different users. We
cannot be certain that near term reductions in water allocations to
manufacturers will not occur.

Our stock price is volatile.

The market price of our common stock has fluctuated significantly to date.
In addition, the market price of the common stock could be subject to
significant fluctuations due to general market conditions and in response to
quarter-to-quarter variations in:

. our anticipated or actual operating results;

. announcements or introductions of new products;

. technological innovations or setbacks by us or our competitors;

. conditions in the semiconductor, telecommunications, data
communications, ATE, high-speed computing or military markets;

. the commencement of litigation;

. changes in estimates of the Company's performance by securities
analysts;

. announcements of merger or acquisition transactions; and

. other events or factors.

In addition, the stock market in recent years has experienced extreme price
and volume fluctuations that have affected the market prices of many high
technology companies, particularly semiconductor companies, and that have
often been unrelated or disproportionate to the operating performance of
companies. These fluctuations, as well as general economic and market
conditions, may affect adversely the market price of our common stock.

If we are not adequately prepared for the transition to Year 2000, our
business, operating results and financial condition could suffer.

As a semiconductor manufacturer with our own wafer fabrication facility, we
are dependent on computer systems and manufacturing equipment with embedded
hardware or software to conduct our business. We have developed and are
currently executing a plan designed to make our computer systems,
applications, computer and manufacturing equipment and facilities Year 2000
ready. The plan covers five stages including:

(i) inventory;

(ii) assessment;

(iii) remediation;

(iv) testing; and

(v) contingency planning.

The inventory and assessment stages were completed in March 1999. The
remediation, testing and contingency planning stages are targeted to be
completed in October 1999. We will primarily utilize internal resources to
reprogram, or replace where necessary, and test the software for Year 2000
modifications.

We have initiated communications with our critical external suppliers to
determine the extent to which we may be vulnerable to their failure to resolve
their own Year 2000 issues. Where practicable, we will assess and

26

attempt to mitigate our risks with respect to the failure of these entities to
be Year 2000 ready. The effect, if any, on our results of operations from the
failure of such parties to be Year 2000 ready, is not reasonably estimable.

As of March 31, 1999, we have incurred and expensed approximately $200,000
related to the Year 2000 project and expect to incur an additional $700,000 on
completing the Year 2000 project. Approximately one-half the costs associated
with the Year 2000 project will be internal resources that have been
reallocated from other projects, with the balance of costs reflecting
incremental spending for equipment and software upgrades. The costs of the
Year 2000 Project will be funded through operating cash flows, with the cost
of internal resources expensed as incurred and the cost of equipment and
software upgrades capitalized or expensed in accordance with our policy on
property and equipment.

The costs of the project and the date on which we plan to complete the Year
2000 modifications are based on management's best estimates, which were
derived utilizing numerous assumptions of future events, including the
continued availability of certain resources, third party modification plans
and other factors. However, there can be no guarantee that these estimates
will be achieved, and actual results could differ materially from those plans.
Among the factors that might cause such material differences are:

. the availability and cost of personnel trained in this area;
. the ability to locate and correct all relevant computer codes; and
. the ability to identify and correct equipment with embedded hardware or
software and similar uncertainties.

The anti-takeover provisions of our certificate of incorporation and of the
Delaware General Corporation Law may delay, defer or prevent a change of
control.

Our board of directors has the authority to issue up to 2,000,000 shares of
preferred stock and to determine the price, rights, preferences and privileges
and restrictions, including voting rights, of those shares without any further
vote or action by our stockholders. The rights of the holders of common stock
will be subject to, and may be adversely affected by, the rights of the
holders of any shares of preferred stock that may be issued in the future. The
issuance of preferred stock may delay, defer or prevent a change in control of
AMCC, as the terms of the preferred stock that might be issued could
potentially prohibit our consummation of any merger, reorganization, sale of
substantially all of our assets, liquidation or other extraordinary corporate
transaction without the approval of the holders of the outstanding shares of
preferred stock. In addition, the issuance of preferred stock could have a
dilutive effect on stockholders of AMCC. Section 203 of the Delaware General
Corporation Law, to which we are subject, restricts certain business
combinations with any "interested stockholder" as defined by this statute. The
statute may also delay, alter or prevent a change of control.

Item 2. Properties.

The Company's executive offices, marketing and engineering functions are
located in San Diego, California in a 90,000 square foot building that is
leased by the Company under a lease that expires in 2007. In addition, the
Company occupies a 21,000 square foot building in San Diego, which houses the
Company's manufacturing facilities under a lease that expires in 2003, but
provides the Company with an option to extend the lease for one additional
five year period.

In July 1998 the Company acquired the right to purchase, in the form of a
ground lease, a parcel of land as a site for a potential new wafer fabrication

(b) Recent Sales of Unregistered Securities

(1) From December 31, 1997 until March 2, 1998, 26,997 shares of Common
Stock were issued upon exercise of options with an average exercise price
of $.45 per share, all of which were paid in cash, and 56,645 shares of
Common Stock were issuable upon exercise of outstanding options with an
average exercise price of $.46 per share pursuant to grants to certain
employees and Directors of the Company under the Company's 1982 Incentive
Stock Option Plan (the "1982 Plan"). On March 2, 1998, the Company filed a
Registration Statement on Form S-8 to cover the shares of Common Stock
issuable upon exercise of options under the 1992 Plan.

(2) From December 31, 1997 until March 2, 1998, 120,719 shares of Common

(3) On March 17, 1999, AMCC acquired all the outstanding stock of Cimaron
Communications, pursuant to a merger of AMCC and Cimaron Communications
Corporation ("Cimaron"). Under the terms of the related merger agreement,
all of the outstanding stock and stock equivalents of Cimaron were
exchanged for approximately three million shares of the Company's Common
Stock. At the time of the transaction, the shares of the Company's Common
Stock issued to the former Cimaron stockholders were not registered under
the Securities Act because the transaction involved a non-public offering
exempt from registration under Section 4(2) of the Securities Act and
Regulation D promulgated thereunder. On April 13, 1999, the Company filed a
registration statement on Form S-3 to cover the shares of Common Stock
issued pursuant to the merger agreement.

There were no underwritten offerings in connection with any of the
transactions set forth in Items 5(b)(1) through 5(b)(3) above. The issuances
described in Items 5(b)(1) and 5(b)(2) above were deemed to be exempt from
registration under the Securities Act in reliance upon Rule 701 promulgated
thereunder in that they were

29

offered and sold pursuant to a written compensation plan. In addition, such
issuances were deemed to be exempt from registration under the Securities Act
under Section 4(2) of the Securities Act as transactions not involving any
public offering. The recipients of securities in each of the transactions
described in Items 5(b)(1) and 5(b)(2) above represented their intentions to
acquire the securities for investment only and not with a view to or for sale
in connection with any distribution thereof, and appropriate legends were
affixed to the securities issued in such transactions. All recipients had
adequate access, through their relationships with the Company, to information
about the Company.

operations of the Company should be read in conjunction with the consolidated
financial statements and notes thereto included elsewhere in the Company's
Annual Report on Form 10-K. This discussion contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ materially from those anticipated in these forward-looking
statements as a result of certain factors, including, but not limited to,
those set forth under "Factors That May Affect Future Results" in the
Company's Form 10-K. Readers are cautioned not to place undue reliance on

Overview

AMCC designs, develops, manufactures and markets high-performance, high-
bandwidth silicon solutions for the world's communications infrastructure. The
Company tailors solutions to customer and market requirements by using a
combination of high-frequency analog, mixed-signal and digital design
expertise coupled with system-level knowledge and multiple silicon process
technologies. AMCC believes that its internal bipolar and BiCMOS processes,
complemented by advanced CMOS and silicon germanium processes from external
foundries, enable the Company to offer high-performance, high- speed solutions
optimized for specific applications and customer requirements. The Company
further believes that its products provide significant cost, power,
performance and reliability advantages for system OEMs in addition to
accelerating time-to-market. The Company also leverages its technology to
provide products for the automated test equipment (ATE), high-speed computing
and military markets.

On March 17, 1999, the Company acquired Cimaron Communications Corporation
("Cimaron") in a business combination accounted for as a pooling-of-interests.
Cimaron, which also designs and develops high-bandwidth silicon solutions for
communications equipment manufacturers, became a wholly owned subsidiary of
the Company through the exchange of approximately three million shares of the
Company's Common Stock for all the outstanding stock and options of Cimaron.
The financial statements for fiscal 1999 have been prepared as if the
companies had been combined for the full year and the prior year financial
statements did not require restatement as a result of this business
combination.

Comparison of the Year Ended March 31, 1999 to the Year Ended March 31, 1998

Net Revenues. Net revenues for the year ended March 31, 1999 were
approximately $105.0 million, representing an increase of 37% over net
revenues of approximately $76.6 million for the year ended March 31, 1998.
Revenues from sales of communications products increased 56% in the year ended
March 31, 1999 from $36.6 million or 48% of net revenues for the year ended
March 31, 1998 to $57.3 million or 55% of net revenues for the year ended
March 31, 1999, reflecting unit growth in shipments of existing products, as
well as the introduction of new products for these markets. Revenues from
sales of products to other markets, consisting of the ATE, high-speed
computing and military markets, decreased from 52% of net revenues for the
year ended March 31, 1998, to 45% of net revenues for the year ended March 31,
1999, although revenues from sales to these other markets increased in
absolute dollars. The increase in absolute dollars in revenues attributed to
these other markets was primarily due to $10.0 million of shipments in the
year ended March 31, 1999, relating to the partial fulfillment of an end-of-
life order from Raytheon Systems Co. Total sales to Raytheon Systems Co.
accounted for 16% of net revenues in the year ended March 31, 1999 and were
less than 10% of net revenues in the year ended March 31, 1998. Sales to
Nortel accounted for 20% and 21% of net revenues for the years ended March 31,
1999 and 1998, respectively. In the years ended March 31, 1999 and 1998,
Insight Electronics, Inc., the Company's domestic distributor, accounted for
13% and 11% of net revenues, respectively. Sales outside of North America
accounted for 24% and 23% of net revenues for the years ended March 31, 1999
and 1998, respectively. Although less than seven percent of the Company's
revenues were attributable to sales in Asia for the year ended March 31, 1999,
the recent economic instability in certain Asian countries could adversely
affect the Company's business, financial condition and operating results,
particularly to the extent that this instability impacts the sales of products
manufactured by the Company's customers.

34

Gross Margin. Gross margin was 63.9% for the year ended March 31, 1999, as
compared to 55.2% for the year ended March 31, 1998. The increase in gross
margin resulted from increased utilization of the Company's wafer fabrication
facility. The Company's gross margin is primarily impacted by factory
utilization, manufacturing yields, product mix and the Company's timing of
depreciation expense and other costs associated with expanding its
manufacturing capacity. Although AMCC does not expect its gross margin to
continue to increase at the rate reflected above, its strategy is to maximize
factory utilization whenever possible, maintain or improve its manufacturing
yields, and focus on the development and sales of high-performance products
that can have higher gross margins. There can be no assurance, however, that
the Company will be successful in achieving these objectives. In addition,
these factors can vary significantly from quarter to quarter, which would
likely result in fluctuations in quarterly gross margin and net income.

Research and Development. Research and development ("R&D") expenses
increased 69% to approximately $22.5 million, or 21.4% of revenues, for the
year ended March 31, 1999, from approximately $13.3 million, or 17.3% of net
revenues, for the year ended March 31, 1998. The substantial increase in R&D
expenses was due to the Company's acquisition of Cimaron, which incurred
approximately $2.5 million of R&D expenses during its fiscal year, and
accelerated new product and process development efforts, including a
$3.2 million increase in compensation costs, and a $3.9 million increase in
prototyping and outside contractor costs. The Company believes that a
continued commitment to R&D is vital to maintain a leadership position with
innovative communications products. Accordingly, the Company expects R&D
expenses to increase in absolute dollars and possibly as a percentage of net
revenues in the future. Currently, R&D expenses are focused on the development
of products and processes for the communications markets, and the Company
expects to continue this focus.

Selling, General and Administrative. Selling, general and administrative
("SG&A") expenses were approximately $18.3 million, or 17.5% of revenues, for
the year ended March 31, 1999, as compared to approximately $14.3 million, or
18.6% of net revenues, for the year ended March 31, 1998. The increase in SG&A
expenses for the year ended March 31, 1999 was primarily due to a $2.1 million
increase in personnel costs, a $500,000 increase in commissions earned by
third-party sales representatives, a $500,000 increase in product promotion
expenses and, a $400,000 increase in legal and accounting costs. A portion of
such increases was due to the Company's acquisition of Cimaron. The decrease
in SG&A expenses as a percentage of net revenues for the year ended March 31,
1999 was a result of net revenues increasing more rapidly than SG&A expenses.
The Company expects SG&A expenses to increase in the future due principally to
additional staffing in the Company's sales and marketing departments, as well
as increased spending on information technology, and increased product
promotion expenses.

Merger-related costs. In March 1999, the Company acquired all of the
outstanding common stock and common stock equivalents of Cimaron
Communications Corporation ("Cimaron") in exchange for approximately three
million shares of the Company's common stock. The acquisition has been
accounted for using the pooling-of-interests method of accounting. Costs
associated with this merger of $2.3 million or $0.08 per diluted share were
expensed in the quarter ended March 31, 1999.

Operating Margin. The Company's operating margin increased to 22.8% of net
revenues for the year ended March 31, 1999, compared to 19.3% for the year
ended March 31, 1998, principally as a result of the increase in gross margin
and decrease in SG&A expenses as a percentage of net revenues, partially
offset by the increase in R&D expenses as a percentage of net revenues.

Net Interest Income. Net interest income increased to $3.5 million for the
year ended March 31, 1999 compared to $871,000 for the year ended March 31,
1998. This increase was due principally to higher interest income from larger
cash and short-term investment balances generated from operations and the
proceeds from the Company's public offerings completed during the second half
of the year ended March 31, 1998.

Income Taxes. The Company's annual effective tax rate for the year ended
March 31, 1999, which approximated statutory rates, was 37.4%, compared to an
effective tax rate of 2.6% for the year ended March 31,

35

1998. The effective tax rate for the year ended March 31, 1998 was decreased
from statutory rates due to the reduction of a valuation allowance recorded
against deferred tax assets for net operating loss carryforwards and credits.
The Company expects the tax rate for fiscal 2000 to approximate statutory
rates.

Diluted Earnings per share. Diluted earnings per share decreased 17% to
$0.62 in the year ended March 31, 1999, compared to $0.75 for the year ended
March 31, 1998. The decrease reflects the merger related costs of 2.3 million,
the increase in the effective tax rate, and the greater number of shares
outstanding due in part to the Cimaron acquisition, offset in part by the
increase in operating income in fiscal 1999.

Deferred Compensation. In connection with the grant of certain stock options
to employees during the six months ended September 30, 1997, the Company
recorded aggregate deferred compensation of $599,000, representing the
difference between the deemed fair value of the Common Stock at the date of
grant for accounting purposes and the option exercise price of such options.
Additionally, during the year ended March 31, 1999, the Company recorded
deferred compensation of $2.5 million related to restricted stock and options
granted to founders and employees of Cimaron. Such amounts are presented as a
reduction of stockholders' equity and amortized ratably over the vesting
period of the applicable options. Amortization of deferred compensation
recorded for the years ended March 31, 1998 and 1999 were $127,000 and
$860,000, respectively. The Company currently expects to record amortization
of deferred compensation with respect to these option grants of approximately
$658,000, $543,000, $414,000, $330,000 and $178,000 during the fiscal years
ended March 31, 2000, 2001, 2002, 2003 and 2004, respectively.

Backlog. The Company's sales are made primarily pursuant to standard
purchase orders for delivery of products. Quantities of the Company's products
to be delivered and delivery schedules are frequently revised to reflect
changes in customer needs, and customer orders can be canceled or rescheduled
without significant penalty to the customer. For these reasons, the Company's
backlog as of any particular date is not representative of actual sales for
any succeeding period, and the Company therefore believes that backlog is not
a good indicator of future revenue. The Company's backlog for products
requested to be shipped and non-recurring engineering services to be completed
in the next six months was $38.2 million on March 31, 1999, compared to
$30.1 million on March 31, 1998. Included in backlog at March 31, 1999 is the
$9.3 million balance of an order received from Raytheon Systems Co. related to
an end-of-life buy for integrated circuits used in its high speed radar
systems.

Year 2000 Compliance. As a semiconductor manufacturer with its own wafer
fabrication facility, the Company is dependent on computer systems and
manufacturing equipment with embedded hardware or software to conduct its
business. The Company has developed and is currently executing a plan designed
to make its computer systems, applications, computer and manufacturing
equipment and facilities Year 2000 ready. The plan covers five stages
including (i) inventory, (ii) assessment, (iii) remediation, (iv) testing, and
(v) contingency planning. The Company has completed the inventory and
assessment stages. The remediation, testing and contingency planning stages
are targeted to be completed by October 1999. The Company will primarily
utilize internal resources to reprogram, or replace where necessary, and test
the software for Year 2000 modifications.

The Company is in the process of communicating with its critical external
suppliers to determine the extent to which the Company may be vulnerable to
such parties' failure to resolve their own Year 2000 issues. Where
practicable, the Company will assess and attempt to mitigate its risks with
respect to the failure of these entities to be Year 2000 ready. The effect, if
any, on the Company's results of operations from the failure of such parties
to be Year 2000 ready cannot reasonably be estimated.

The Company has developed contingency plans for certain critical
applications and is working on such plans for others. These contingency plans
involve, among other actions, manual workarounds, and adjusting staffing
strategies.

The Company has incurred and expensed approximately $200,000 related to the
Year 2000 project and expects to incur an additional $700,000 on completing
the Year 2000 project. Approximately one-half of the costs associated with the
Year 2000 project are expected to relate to internal resources that have been
reallocated

36

from other projects, with the balance of costs reflecting incremental spending
for equipment and software upgrades. The costs of the Year 2000 project are
expected to be funded through operating cash flows, with the cost of internal
resources expensed as incurred and the cost of equipment and software upgrades
capitalized or expensed in accordance with the Company's policy on property
and equipment.

The costs of the project and the date on which the Company plans to complete
the Year 2000 modifications are based on management's best estimates, which
were derived utilizing numerous assumptions of future events including the
continued availability of certain resources, third party modification plans
and other factors. However, there can be no guarantee that these estimates
will be achieved and actual results could differ materially from those plans.
Specific factors that might cause such material differences include, but are
not limited to, the availability and cost of personnel trained in this area,
the ability to locate and correct all relevant computer codes and the ability
to identify and correct equipment with embedded hardware or software and
similar uncertainties.

Comparison of the Year Ended March 31, 1998 to the Year Ended March 31, 1997

Net Revenues. Net revenues for the year ended March 31, 1998 were
approximately $76.6 million, representing an increase of 33% over net revenues
of approximately $57.5 million for the year ended March 31, 1997. Revenues
from sales of communications products increased from 44% of net revenues for
the year ended March 31, 1997 to 48% of net revenues for the year ended March
31, 1998, reflecting unit growth in shipments of existing products, as well as
the introduction of new products for these markets. Revenues from sales of
products to other markets, consisting of the ATE, high-speed computing and
military markets, decreased from 56% of net revenues for the year ended March
31, 1997, to 52% of net revenues for the year ended March 31, 1998, although
revenues from sales to these other markets increased in absolute dollars. The
increase in absolute dollars in revenues attributed to these other markets was
primarily due to an increase in shipments of PCI bus products for high-speed
computing applications and to increased shipments of products to the ATE
market. Sales to Nortel accounted for 21% and 20% of net revenues for the
years ended March 31, 1998 and 1997, respectively. In the year ended March
31,1998, one other customer, Insight Electronics, Inc., the Company's domestic
distributor, accounted for 11% of net revenues. Sales outside of North America
accounted for 23% and 21% of net revenues for the years ended March 31, 1998
and 1997, respectively.

Gross Margin. Gross margin was 55.2% for the year ended March 31, 1998, as
compared to 47.7% for the year ended March 31, 1997. The significant increase
in gross margin primarily resulted from increased utilization of the Company's
wafer fabrication facility, as well as a $1.1 million improvement in
manufacturing yields.

Research and Development. Research and development ("R&D") expenses
increased 69% to approximately $13.3 million, or 17.3% of net revenues, for
the year ended March 31, 1998, from approximately $7.9 million, or 13.7% of
net revenues, for the year ended March 31, 1997. The substantial increase in
R&D expenses was due to accelerated new product and process development
efforts including a $3.4 million increase in compensation costs, and a $1.6
million increase in prototyping and outside contractor costs.

Selling, General and Administrative. Selling, general and administrative
("SG&A") expenses were approximately $14.3 million, or 18.6% of net revenues,
for the year ended March 31, 1998, as compared to approximately $12.5 million,
or 21.8% of net revenues, for the year ended March 31, 1997. The increase in
SG&A expenses for the year ended March 31, 1998 was primarily due to a
$700,000 increase in compensation costs and a $600,000 increase in commissions
earned by third-party sales representatives. The decrease in SG&A expenses as
a percentage of net revenues for the year ended March 31, 1998 was a result of
net revenues increasing more rapidly than SG&A expenses.

Operating Margin. The Company's operating margin increased to 19.3% of net
revenues for the year ended March 31, 1998, compared to 12.2% for the year
ended March 31, 1997, principally as a result of the increase in gross margin
and decrease in SG&A expenses as a percentage of net revenues, partially
offset by the increase in R&D expenses as a percentage of net revenues.

37

Net Interest Income. Net interest income increased to $871,000 for the year
ended March 31, 1998 from a net interest expense of $29,000 for the year ended
March 31, 1997. This increase was due principally to a $600,000 increase in
interest income resulting from larger cash and short-term investment balances
generated by the proceeds from the Company's public offerings completed during
the year ended March 31, 1998, as well as a $300,000 decrease in interest
expense associated with outstanding capital lease and debt obligations.

Income Taxes. The Company's annual effective tax rate for the year ended
March 31, 1998 was 2.6%. This was due primarily to the reduction of a
valuation allowance recorded against deferred tax assets for net operating
loss carryforwards and credits in the prior two years. This reduction results
from sufficient levels of income for fiscal 1998, which made the realization
of these deferred tax assets more likely than not. The effective tax rate of
9.5% for the year ended March 31, 1997 was attributable primarily to
alternative minimum taxes ("AMT").

Diluted Earnings per share. Diluted earnings per share increased 114% to
$0.75 in the year ended March 31, 1998, compared to $0.35 for the year ended
March 31, 1997.

Liquidity and Capital Resources

The Company's principal source of liquidity as of March 31, 1999 consisted
of $86.5 million in cash, cash equivalents and short-term investments. Working
capital as of March 31, 1999 was $103.6 million, compared to $77.4 million as
of March 31, 1998. This increase in working capital was primarily due to cash
provided by operating activities and the proceeds from the sale of common
stock, offset by the purchase of property, equipment and other assets.

For the years ended March 31, 1999, 1998 and 1997, net cash provided by
operating activities was $22.0 million, $16.9 million and $11.7 million,
respectively. Net cash provided by operating activities in fiscal 1999
primarily reflected net income before depreciation and amortization expense
plus increased accrued liabilities less increases in accounts receivable and
inventories. Net cash provided by operating activities in fiscal 1998
primarily reflected net income before depreciation and amortization expense
plus increases in accounts payable and accrued liabilities less increases in
accounts receivable and deferred income taxes. Net cash provided by operating
activities in fiscal 1997 primarily reflected net income before depreciation
and amortization expense.

Capital expenditures and the purchase of other assets totaled $16.5 million,
$11.6 million and $4.1 million for the years ended March 31, 1999, 1998 and
1997, respectively, of which $6.7 million, $3.6 million and $1.2 million for
the years ended March 31, 1999, 1998 and 1997, respectively, were financed
using debt or capital leases. In fiscal year 2000, the Company expects to
incur approximately $14.0 million in capital expenditures for manufacturing
and test equipment, computer hardware and software and the acquisition of land
as a site for a potential new wafer fabrication facility. The Company is
exploring alternatives for the expansion of its manufacturing capacity which
would likely occur after fiscal year 2000, including expanding its current 4"
wafer fabrication facility, building a new wafer fabrication facility,
purchasing a wafer fabrication facility and entering into strategic
relationships to obtain additional capacity. Any of these alternatives could
require a significant investment by the Company including an investment in
excess of $80.0 million if the Company chose to or was required to build a new
wafer fabrication facility. The Company would anticipate financing any such
investment through a combination of available cash, cash equivalents and short
term investments, cash from operations and debt and lease financing. Although
the Company believes that it will be able to obtain financing for a
significant portion of the planned capital expenditures at competitive rates
and terms from its existing and new financing sources, there can be no
assurance that the Company will be successful in these efforts. Furthermore,
there can be no assurance that any of the alternatives for expansion of its
manufacturing capacity will be available on a timely basis or at all.

The Company believes that its available cash, cash equivalents and short-
term investments, and cash generated from operations, will be sufficient to
meet the Company's capital requirements for the next 12 months, although the
Company could be required, or could elect, to seek to raise additional capital
during such period. The Company expects that it will need to raise additional
debt or equity financing in the future. There can be no

38

assurance that such additional debt or equity financing will be available on
commercially reasonable terms or at all.

Factors That May Affect Future Results

The Company's results of operations have varied significantly in the past
and may continue to do so in the future. These variations have been, and may
in the future be, due to a number of factors, any of which could have a
material adverse effect on the Company's business, financial condition and
results of operations. These factors include, but are not limited to: the
rescheduling or cancellation of orders by customers; fluctuations in the
timing and amount of customer requests for product shipments; fluctuations in
manufacturing yields and inventory levels; changes in product mix; the
Company's ability to introduce new products and technologies on a timely
basis; the introduction of products and technologies by the Company's
competitors; the availability of external foundry capacity, purchased parts
and raw materials; competitive pressures on selling prices; the timing of
investments in research and development; market acceptance of the Company's
and its customers' products; the integration of operations and personnel as
the result of the Company's recent acquisition of Cimaron; the timing of
depreciation and other expenses to be incurred by the Company in connection
with the increase of capacity for its existing manufacturing facility and in
connection with its proposed new manufacturing facility; the timing and amount
of recruiting and relocation expenses, prototyping costs and product
promotional expenses; costs associated with future litigation, if any,
including without limitation, litigation relating to the use or ownership of
intellectual property; costs associated with compliance with applicable
environmental regulations; general semiconductor industry conditions; and
general economic conditions. Historically, average selling prices in the
semiconductor industry have decreased over the life of a product, and as a
result, the average selling prices of the Company's products may be subject to
significant pricing pressures in the future. Because the Company is continuing
to increase its operating expenses for personnel and new product development,
and because the Company is limited in its availability to reduce expenses
quickly in response to any revenue short falls, the Company's business,
financial condition and operating results would be adversely affected if
increased sales are not achieved. In addition, the Company's operating results
may be below the expectations of public market analysts or investors, which
could have a material adverse effect on the market price of the Common Stock.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

At March 31, 1999, the Company's investment portfolio includes fixed-income
securities of $73 million. These securities are subject to interest rate risk
and will decline in value if interest rates increase. Due to the short
duration of the Company's investment portfolio, an immediate 100 basis point
increase in interest rates would have no material impact on the Company's
financial condition or results of operations.

The Company generally conducts business, including sales to foreign
customers, in U.S. dollars and as a result, has limited foreign currency
exchange rate risk. The effect of an immediate 10 percent change in foreign
exchange rates would not have a material impact on the Company's financial
condition or results of operations.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors
Applied Micro Circuits Corporation

We have audited the accompanying consolidated balance sheets of Applied
Micro Circuits Corporation as of March 31, 1998 and 1999, and the related
consolidated statements of income, stockholders' equity, and cash flows for
each of the three years in the period ended March 31, 1999. Our audits also
included the financial statement schedule listed in the index at Item 14(a).
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Applied Micro Circuits Corporation at March 31, 1998 and 1999, and the
consolidated results of its operations and its cash flows for each of the
three years in the period ended March 31, 1999, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, present fairly in all material respects the
information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Business

The Company designs, develops, manufactures and markets high-performance,
high-bandwidth silicon solutions for the world's communications
infrastructure.

Basis of Presentation

The consolidated financial statements include all the accounts of the
Company and its wholly-owned subsidiaries. All significant intercompany
balances and transactions have been eliminated in consolidation. On March 17,
1999, the Company acquired Cimaron Communications Corporation ("Cimaron") in a
business combination accounted for as a pooling-of-interests. Cimaron, which
also designs and develops high-bandwidth silicon solutions for communications
equipment manufacturers, became a wholly owned subsidiary of the Company
through the exchange of approximately three million shares of the Company's
common stock for all the outstanding stock and stock options of Cimaron. The
accompanying financial statements for fiscal 1999 have been prepared as if the
companies had been combined for the full year, and as more fully discussed in
Note 2, the prior year financial statements did not require restatement as a
result of this business combination.

Cash, Cash Equivalents and Short-Term Investments

Cash and cash equivalents consist of money market type funds and highly
liquid debt instruments with original maturities of three months or less at
the date of acquisition. Short-term investments consist of United States
Treasury notes, obligations of U.S. government agencies and corporate bonds.
The Company maintains its excess cash in financial institutions with strong
credit ratings and has not experienced any significant losses on its
investments.

The Company classifies its short-term investments as "Available-for-Sale"
and records such assets at the estimated fair value with unrealized gains and
losses excluded from earnings and reported, net of tax, in comprehensive
income. The basis for computing realized gains or losses is by specific
identification.

The following is a summary of available-for-sale securities (in thousands):

Gross Unrealized

The estimated fair value of the short term investments was equal to the
amortized cost at March 31, 1998.

-------
$73,010
=======

Fair Value of Financial Instruments

The carrying value of cash equivalents, short-term investments, accounts
receivable, accounts payable, accrued liabilities and long term debt
approximates fair value.

Concentration of Credit Risk

The Company believes that the concentration of credit risk in its trade
receivables is mitigated by the Company's credit evaluation process,
relatively short collection terms and dispersion of its customer base. The
Company generally does not require collateral and has not experienced
significant losses on trade receivables from any particular customer or
geographic region for any period presented.

The Company invests its excess cash in debt instruments of the U.S.
Treasury, governmental agencies and corporations with strong credit ratings.
The Company has established guidelines relative to diversification and
maturities that attempt to maintain safety and liquidity. These guidelines are
periodically reviewed and modified to take advantage of trends in yields and
interest rates. The Company has not experienced any significant losses on its
cash equivalents or short-term investments.

Use of Estimates

The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
disclosures made in the accompanying notes to the financial statements. These
estimates include assessing the collectability of accounts receivable, the use
and recoverability of inventory, estimates to complete engineering contracts,
costs of future product returns under warranty and provisions for
contingencies expected to be incurred. Actual results could differ from those
estimates.

Inventories

Inventories are stated at the lower of cost (determined on a first-in,
first-out basis) or market. The Company's inventory valuation process is done
on a part-by-part basis. Lower of cost or market adjustments, specifically
identified on a part-by-part basis, reduce the carrying value of the related
inventory and take into consideration reductions in sales prices, excess
inventory levels and obsolete inventory. Once established, these adjustments
are considered permanent and are not reversed until the related inventory is
sold or disposed.

Property and Equipment

Property and equipment are stated at cost and depreciated over the estimated
useful lives of the assets (3 to 7 years) using the straight line method.
Leasehold improvements are stated at cost and amortized over the useful life
of the asset. Property and equipment under capital leases are recorded at the
net present value of the minimum lease payments and are amortized over the
useful life of the assets. Leased assets purchased at the expiration of the
lease term are capitalized at acquisition cost.

APPLIED MICRO CIRCUITS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Impairment of Long-Lived Assets

In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121, "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets
to Be Disposed Of", the Company records impairment losses on long-lived assets
used in operations when indicators of impairment are present and the
undiscounted cash flows estimated to be generated by those assets are less
than the assets' carrying amounts. SFAS No. 121 also addresses the accounting
for long-lived assets that are expected to be disposed of. Through March 31,
1999, the Company has not experienced any such impairments.

Advertising Cost

Advertising costs are expensed as incurred.

Revenues

Revenues related to product sales are generally recognized when the products
are shipped to the customer. Recognition of revenues and the related cost of
revenues on shipments to distributors that are subject to terms of sale
allowing for price protection and right of return on products unsold by the
distributor are deferred until the distributor's ability to return the
products or its' rights to price protection lapse or have been limited.
Revenues on engineering design contracts are recognized using the percentage-
of-completion method based on actual cost incurred to date compared to total
estimated costs of the project. Deferred revenue represents both the margin on
shipments of products to distributors that will be recognized when the
distributors ship the products to their customers or the right of return has
lapsed and billings in excess and estimated earnings on uncompleted
engineering design contracts.

Warranty Reserves

Estimated expenses for warranty obligations are accrued as revenue is
recognized. Reserve estimates are adjusted periodically to reflect actual
experience.

Research and Development

Research and development costs are expensed as incurred. Substantially all
research and development expenses are related to new product development,
designing significant improvements to existing products and new process
development.

Stock-Based Compensation

The Company has elected to follow Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees ("APB 25") and related
interpretations in accounting for its employee and director stock options
because the alternative fair value accounting provided for under SFAS No. 123,
Accounting for Stock-Based Compensation ("SFAS 123"), requires the use of
option valuation models that were not developed for use in valuing employee
and director stock options. Under SFAS 123 compensation cost is determined
using the fair value of stock-based compensation determined as of the grant
date, and is recognized over the periods in which the related services are
rendered. The statement also permits companies to elect to continue using the
current implicit value accounting method specified in APB 25 to account for
stock-based compensation and disclose in the footnotes to the financial
statements the pro forma effect of using the fair value method for its stock
based compensation.

Reclassification

Certain prior period amounts have been reclassified to conform to the
current period presentation.

Earnings Per Share

Earnings per share are computed in accordance with SFAS No. 128 "Earnings
Per Share." Basic earnings per share are computed using the weighted average
number of common shares outstanding during each period. Diluted earnings per
share includes the dilutive effect of common shares potentially issuable upon
the exercise of stock options.

The reconciliation of shares used to calculate basic and diluted earnings

New Accounting Standards

Effective April 1, 1998, the Company adopted SFAS No. 130 "Reporting
Comprehensive Income" and SFAS No. 131. "Segment Information". SFAS No. 130
requires that all components of comprehensive income, including net income, be
reported in the financial statements in the period in which they are
recognized. Comprehensive income is defined as the change in equity during a
period from transactions and other events and circumstances from non-owner
sources. Net income and other comprehensive income, including unrealized gains
and losses on investments is reported, net of their related tax effect, to
arrive at comprehensive income. SFAS No. 131 amends the requirements for
public enterprises to report financial and descriptive information about its
reportable operating segments. Operating segments, as defined in SFAS No. 131,
are components of an enterprise for which separate financial information is
available and is evaluated regularly by the Company in deciding how to
allocate resources and in assessing performance. The financial information is
required to be reported on the basis that is used internally for evaluating
the segment performance. The Company believes it operates in one business and
operating segment.

2. ACQUISITIONS

On March 17, 1999, AMCC acquired all of the outstanding Common Stock and
Common Stock equivalents of Cimaron in exchange for approximately three
million shares of the Company's Common Stock. The acquisition has been
accounted for using the pooling-of-interests method of accounting. Prior to
the combination, Cimaron, which was incorporated on January 2, 1998, had a
fiscal year end of December 31, 1998. In recording the business combination,
Cimaron's results of operations for the fiscal year ended December 31, 1998
were combined with AMCC's for the fiscal year ended March 31, 1999. Cimaron's
net sales and net loss for the three month period ended March 31, 1999 were
$110,000 and $(1,341,000), respectively. In accordance with Accounting
Principles Board Opinion No. 16 ("APB No. 16"), Cimaron's results of
operations and cash flows for the three month period ended March 31, 1999 have
been added directly to the retained earnings and cash flows of AMCC and
excluded from reported fiscal 1999 results of operations.

The combined Company realized a charge in the fourth quarter of fiscal 1999
of approximately $3.1 million related to the estimated costs of the merger.
Approximately $700,000 of these total merger costs were incurred

by Cimaron and are not reflected in the Company's results of operations for
the fourth quarter of fiscal 1999 because they are included in Cimaron's
results of operations which are reflected as a charge directly to retained
earnings.

In April 1998, the Company acquired Ten Mountains Design which designs and
develops high bandwidth analog devices for communications equipment suppliers
and optical module manufacturers. The purchase price was approximately
$330,000 and resulted in recording intangible assets of approximately $280,000
which will be amortized over three years. The financial statements include the
results of operation for Ten Mountains Design from the date of acquisition.

In November 1997, the Certificate of Incorporation was amended to allow the
issuance of up to 2,000,000 shares of preferred stock in one or more series
and to fix the rights, preferences, privileges and restriction thereof,
including dividend rights, dividend rates, conversion rights, voting rights,
terms of redemption, redemption prices, liquidation preferences and the number
of shares constituting any series of the designation of such series, without
further vote or action by the stockholders.

Stock Options and Other Stock Awards

The Company's 1992 Stock Option Plan ("1992 Plan") provides for the granting
of incentive and nonqualified stock options to employees. Generally, options
are granted at prices at least equal to fair value of the Company's Common
Stock on the date of grant. In addition, certain officers, employees and
directors have been granted nonqualified stock options. The Company's 1982
Employee Incentive Stock Option Plan expired in 1992.

In connection with the Company's acquisition of Cimaron, the Company assumed
options and other stock awards granted under Cimaron's 1998 Stock Incentive
Plan ("The Incentive Plan") covering 657,153 shares of

F-12

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Common Stock at a weighted average exercise price of $.23 per share. The terms
of the plan provides for the granting of options, restricted stock, or other
stock based awards ("stock awards") to employees, officers, directors,
consultants and advisors. Generally, the stock awards are granted at prices at
least equal to the fair value of the Company's Common Stock on the date of
grant. A total of 1,016,365 shares of Common Stock were authorized for
issuance under the Incentive Plan. At March 31, 1999, 564,358 restricted
shares had been issued under the Incentive Plan.

Options and other stock awards under the plans expire not more than ten
years from the date of grant and are either immediately exercisable after the
date of grant but are subject to certain repurchase rights by the Company, at
the Company's option, until such ownership rights have vested or exercisable
upon vesting. Vesting generally occurs over four to five years. At March 31,
1998 and 1999, 651,842 and 869,626 shares of Common Stock were subject to
repurchase, respectively.

Pursuant to an employment agreement entered into during January 1996,
between the Company and an executive, the Company granted an option to
purchase 800,000 shares of the Company's Common Stock at $0.53 per share under
the 1992 Stock Option Plan. The option vests ratably over four years. In the
event the Company is acquired, the agreement stipulates that under certain
circumstances the executive is eligible for certain additional compensation.
These options as well as 66,667 additional options issued in April 1997 were
exercised in July 1997. The exercise was paid for with various notes, which
aggregated $455,000 and bear interest at rates between 5.98% and 6.54%, and
are due at the earlier of February 12, 2000 ($420,000) and April 9, 2001
($35,000) or the termination of employment.

Pro forma information regarding net income and net income per share is
required by SFAS No. 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of that
statement. The fair value of the options was estimated at the date of grant
using the minimum value method for grants prior to the initial public offering
and the Black Scholes method for grants after the initial public offering
using the following weighted average assumptions for fiscal year 1997 and
1998; risk free interest rate of 6%; an expected option life of four years; no
annual dividends, and an expected volatility of .92 (used only for the options
valued using the Black Scholes method.). For options granted in fiscal year
1999, the fair value of the options was estimated at the date of the grant
using the following assumptions; risk free interest rate of 6%; an expected
life of four to five years; no annual dividends and an expected volatility of
.89.

For purposes of pro forma disclosures, the estimated fair value of the
options is amortized ratably to expenses over the vesting period of such
options. The effects of applying SFAS No. 123 for pro forma disclosure
purposes are not likely to be representative of the effects on pro forma net
income in future years because they do not take into consideration pro forma
compensation expenses related to grants made prior to 1996.

11. CONTINGENCIES

The Company is party to various claims and legal actions arising in the
normal course of business, including notification of possible infringement on
the intellectual property rights of third parties. In addition, since 1993 the
Company has been named as a potentially responsible party ("PRP") along with a
large number of other companies that used Omega Chemical Corporation ("Omega")
in Whittier, California to handle and dispose of certain hazardous waste
material. The Company is a member of a large group of PRPs that has agreed to
fund certain remediation efforts at the Omega site for which the Company has
accrued approximately $50,000. Although the ultimate outcome of these matters
is not presently determinable, management believes that the resolution of all
such pending matters, net of amounts accrued, will not have a material adverse
affect on the Company's financial position or liquidity; however, there can be
no assurance that the ultimate resolution of these matters will not have a
material impact on the Company's results of operations in any period.

On July 31, 1998, the Lemelson Medical, Education & Research Foundation
Limited Partnership (the "Lemelson Partnership") filed a lawsuit in the U.S.
District Court for the District of Arizona against 26 companies, including the
Company, engaged in the manufacture and/or sale of IC products. On
November 25, 1998 the Company was served a summons pursuant to this lawsuit.
The complaint alleges infringement by the defendants of certain U.S. patents
(the "Lemelson Patents") held by the Lemelson Partnership relating to certain
semiconductor manufacturing processes. The complaint seeks, among other
things, injunctive relief and unspecified treble damages. Previously, the
Lemelson Partnership has offered the Company a license under the Lemelson
patents. The Company is monitoring this matter and, although the ultimate
outcome of this matter is not currently determinable, the Company believes,
based in part on the licensing terms previously offered by the Lemelson
Partnership, that the resolution of this matter will not have a material
adverse effect on the Company's financial position or liquidity; however,
there can be no assurance that the ultimate resolution of this matter will not
have a material adverse effect on the Company's results of operations in any
period.
