PART I

ITEM 1. BUSINESS

OVERVIEW

Mercury Computer Systems, Inc. (the "Company" or "Mercury") designs,
manufactures and markets high performance, real-time digital signal and image
processing computer systems that transform sensor generated data into
information which can be displayed as images for human interpretation or
subjected to additional computer analysis. These multicomputer systems are
heterogeneous and scalable, allowing them to accommodate several different
microprocessor types and to scale from a few to hundreds of microprocessors
within a single system. Mercury's system architecture is specifically designed
for digital signal processing ("DSP") and image processing applications, which
are typically computation intensive and require I/O capacity and interprocessor
bandwidth not available on a general purpose PC or workstation.

The two primary markets for Mercury's products are defense electronics and
medical diagnostic imaging markets. Both of these markets have computing needs
which benefit from the unique system architecture developed by the Company.
Mercury's computer systems are generally used on real-world sensor-generated
data to enable a military commander to "see" the battle space through natural
barriers such as clouds, darkness, water or foliage, so that the position and
strength of the enemy can be determined, or to enable a physician to "see"
within the body instead of performing invasive surgery.

During the past several years, the majority of the Company's revenues have
been generated from sales of its products to the defense electronics market,
generally for use in reconnaissance and intelligence gathering systems. The
Company's activities in this area have focused on the proof of concept,
development and deployment of advanced military applications in radar, sonar and
airborne surveillance. The Company has established relationships with many of
the major prime contractors to the worldwide defense industry, including
Lockheed Martin Corporation, Raytheon Systems Company, Northrop Grumman
Corporation, MIT/Lincoln Laboratory, Alenia Marconi Systems, Ericsson Microwave
Systems AB, Mitsubishi Electronics, BAE Systems, UK's Defense Evaluation and
Research Agency, and NEC.

Medical diagnostic imaging is the other primary market currently served by
the Company. Mercury's computer systems are embedded in Magnetic Resonance
Imaging ("MRI"), Computed Tomography ("CT"), Positron Emission Tomography
("PET"), and digital x-ray machines. Mercury has supplied computer systems for
use in several of GE Medical Systems' diagnostic imaging systems since 1987, and
has established relationships with Siemens Medical Systems, Inc., Philips
Medical Systems Nederland BV, and Marconi Medical Systems, Israel Ltd. The major
medical imaging manufacturers are currently developing the next generation of
MRI, CT and digital x-ray machines, which are expected to provide better
performance at lower cost. Mercury has secured design wins on programs with
certain of the major medical imaging manufacturers for their next generation
MRI, and digital x-ray machines.

Mercury's systems are currently embedded within semiconductor photomask
generation systems manufactured by Micronic Laser Systems AB of Sweden, and
semiconductor wafer inspection systems manufactured by Schlumberger
Semiconductor Solutions. In addition, Mercury has secured multiple design wins
in additional next-generation semiconductor imaging applications.

Mercury's computer systems are designed to process continuous streams of
data from sensors attached to radar, sonar, medical imaging equipment and other
devices. The resulting image is transmitted to the battlefield commander, pilot,
technician or physician in order to assist in decision making or diagnostic
processes. Due to the nature of the applications in which many of Mercury's
computer systems are embedded, they are frequently confined in limited spaces
and therefore are designed to generate a minimum amount of heat. The Company
employs the RACEway Interconnect, an industry standard system area network
developed by Mercury, which allows for high interprocessor communication and
data processing bandwidth and I/O capacity. The Company uses its proprietary
ASICs to integrate microprocessors, memory and related components into the
RACEway Interconnect fabric to provide optimum system performance. The Company
uses multiple industry standard processors, such as Motorola's PowerPC, in the
same system. The Company believes that the RACEway Interconnect and its
proprietary ASICs, working together with a group of mixed microprocessors in the
same system, allow the most efficient use of space and power with an optimal
price/performance ratio.

INDUSTRY BACKGROUND

Defense Electronics

Digital signal and image processing computer systems are embedded into air,
sea and land-based platforms for processing radar, sonar and signal intelligence
applications. The Company believes that an important factor underlying the
development of this market is a continuing desire by military commanders for
increased battle space information, which can be obtained through radar, sonar,
signal intelligence and image intelligence systems. Military commanders also
need more powerful computers with similar attributes in order to conduct dynamic
battle simulations and mission planning tasks utilizing today's complex weapons
systems.

Another important trend in the defense electronics marketplace is the
movement away from so-called "stove pipe" systems designed by prime contractors
with special purpose hardware specifically for a single application, largely
without regard to cost. The market is moving toward the use of systems which
incorporate selected commercial-off-the-shelf ("COTS") hardware and software
components in order to save money and development time. The Department of
Defense ("DOD") leaders and federal regulations have mandated widespread use of
COTS components in defense electronics applications. All of Mercury's computer
systems are eligible for use in defense electronics applications as COTS
components.

Medical Imaging

The principal modalities of medical diagnostic imaging systems include MRI,
CT, digital x-ray, PET, SPECT (single photon emission computed tomography) and
ultrasound devices. The Company believes that demand for medical diagnostic
imaging equipment will increase modestly over the next few years, fueled by the
introduction of next-generation devices, together with the anticipated future
development by the major medical imaging manufacturers of new international
markets for their diagnostic equipment. The Company believes medical imaging
equipment manufacturers will continue to replace in-house designed digital
signal and image processing systems with commercially available systems designed
by the Company and others.

This industry demand is driven in part by the need to provide physicians
with rapid, sharp and clear images of areas of a patient's body suspected to be
diseased or injured, while using the least intrusive means. These images provide
a significant diagnostic tool for the physician, who can more readily understand
the patient's malady and prescribe appropriate corrective action. In order to
provide such images, medical imaging machines must be capable of processing a
continuous stream of data on a real-time basis. A parallel concern in the health
care industry is the need to reduce costs. Hospitals, in particular, continue to
be under significant pressure to contain costs and, at the same time, maintain
quality of care. Such pressures are forcing hospitals to be as technologically
efficient as possible. Toward this end, hospitals seek to reduce the required
period of time a patient must spend in their medical imaging machines, which has
the added benefit of increasing the total number of patients who can be
diagnosed with this expensive equipment during a given period of time. One way
to reduce patient time in medical imaging machines and improve image quality is
to utilize more powerful signal processing computers, such as those supplied by
Mercury.

MARKETS AND CUSTOMERS

Defense Electronics

Mercury provides high performance embedded computer systems as standard
products to the defense electronics market by using commercial and selected
rugged components and by working closely with defense contractors to complete a
design which matches the specified requirements of military applications. The
Company engages in frequent, detailed communication with the end users of
Mercury's systems, military executives and program managers in government and
defense contractors regarding the technical capabilities of Mercury's advanced
signal processing computers and the successful incorporation of its computers in
numerous military programs.

Mercury employs industry specialist managers to monitor the defense programs
of each major branch of the United States armed services and additional managers
based in Europe and Japan to keep abreast of developments in their respective
regions. This approach provides relevant information to Mercury regarding major
military procurements worldwide. Mercury maintains sales and technical support
groups to service defense industry participants in six branch offices in the
United States, and through Mercury's subsidiary offices or distributors in 11
other countries. At Mercury's headquarters in Chelmsford, Massachusetts, a group
of systems engineers specializing in radar, sonar and surveillance problems
provides support on an as-needed basis to the remote offices to assist in
securing inclusion in targeted military programs.

Medical Imaging

Mercury strives to provide a superior combination of high performance and
competitively priced embedded computer systems to the medical imaging market.
The Company focuses on establishing strong relationships with its customers, the
medical equipment manufacturers. By maintaining frequent, in-depth
communications with its customers and working closely with their engineering
groups, the Company is able to understand their needs and provide appropriate
solutions. In addition, the Company intends to continue its efforts to install
its computer systems in place of alternative designs created by the in-house
design teams employed by the medical imaging equipment manufacturers.

The Company currently is working closely with major medical equipment
companies to design the next generation of MRI and digital x-ray systems, which
the Company believes will lead to faster time-to-market and competitive
advantages for the medical equipment companies that use Mercury's computer
systems for inclusion in their imaging machines. Mercury's industrial PC class
hardware system provides the medical imaging industry with increased performance
densities at lower costs and an architecture that


3

accommodates performance upgrades as new technology becomes available.
Integrating the high-bandwidth RACEway Interconnect system area network within
the PCI environment results in highly scalable systems. This allows medical
equipment suppliers to design systems that can satisfy a broad range of
price/performance requirements and meet the needs of global markets, all with
the same Mercury architecture.

Mercury's medical OEM customers consist of the leading manufacturers of
diagnostic imaging equipment. They include GE Medical, headquartered in
Wisconsin, GE Medical Systems Europe in France, GE Yokugawa Medical Systems in
Japan, Siemens Medical in Germany, Philips Medical in the Netherlands, and
Marconi Medical in Israel. These companies have adopted Mercury's PCI or VME
computer systems as part of their developments in either MRI, CT, or digital
x-ray systems and, in the case of some companies, multiple types of systems. The
Company has supplied GE Medical with computer systems for use in three
successive generations of MRI machines from 1987 through the present, as well as
for use in other GE Medical equipment, such as PET.

The Company believes that the principal reason for its medical imaging
design wins is Mercury's experienced team of systems and applications engineers
who work closely with the medical equipment designers and with the Company's
product development engineers. This joint design effort frequently precedes the
first production orders by approximately two to three years. However, once
selected, the production contracts typically continue for the life of the
medical imaging system. In addition, the equipment manufacturers typically offer
computer system upgrades to their customers, potentially resulting in additional
sales of Mercury products.

AgileVision

On September 1, 1999, the Company formed AgileVision LLC, a joint venture
with the Sarnoff Corporation. The venture will use Mercury technology to
design, develop, and deliver products and solutions expected to dramatically
reduce the cost of digital TV infrastructure for the broadcast and cable
markets. The many business uncertainties that attend the new venture make
revenue projections at this time inappropriate. Mercury's share of losses is
reported as a separate line item in its profit and loss statement.

Wireless Communications

During the fourth quarter of fiscal 1999, the Company announced that it will
pursue the wireless communications opportunity internally, offering its
technology and expertise to manufacturers for incorporation within next
generation base stations that require substantially more flexible and powerful
signal processing capabilities. Returns on Mercury's investments in fiscal 2000,
2001, and 2002 would not begin before fiscal 2003. The market opportunity
however, is very large, amounting to several hundred millions of dollars
annually, and it represents an OEM business model, which Mercury understands
well. In this past year, Mercury has carried out extensive activities creating a
business development plan that merges its future technology with the processing
requirements of the evolving wireless infrastructure, designing, manufacturing
and testing a prototype communications computer for use in demonstrating the
Company's capabilities, and a simulation system for testing the results of
incorporating Mercury's intellectual property into a base station.

KEY TECHNOLOGY COMPETENCIES

Many of Mercury's customers share a common requirement: the need to process
high-volume, real-time digital data streams. Whether from an antenna in a
defense application or a medical scanner, the computer must have the ability to
process incoming data as quickly as it is received. Data rates can range from a
few to several hundreds of megabytes per second (or several billion bits per
second). The ability to process this continuous flow of high-bandwidth data is a
fundamental difference between the majority of computing systems in the world
(such as personal computers, workstations and servers) and the computers built
by Mercury.

Mercury has developed a set of core technical strengths specifically
targeted to, and defined by, the application areas of signal, image and digital
media processing. These technical strengths are pivotal to Mercury's success in
the real-time market segments of the defense electronics, medical imaging, and
semiconductor imaging industries and have resulted in the following developments
and capabilities:

Heterogeneous Switched-Fabric Interconnects. Mercury connects different
microprocessor types (RISC, DSP and specialized computing devices) and I/O
devices in a bus-less, high-bandwidth manner based on multi-stage switches in
its system area network. Among the engineering developments which distinguish
Mercury's systems are the RACEway Interconnect built using the multi-port
RACEway crossbar chip which supports high bandwidth point-to-point data
transfers and fibre channel chassis-to-chassis extensions for RACEway in large
system configurations.

Heterogeneous Processor Integration. Mercury has developed several ASICs
which integrate standard microprocessors and special purpose mathematics and
graphics processors into a single heterogenous environment. Mercury develops
systems consisting of different microprocessor types with a single-system
software model. Mercury's processor independent software offers a consistent set


4
5

of software tools and interfaces, which can drive a heterogeneous mix of
microprocessor types, such as Motorola's PowerPC processor and Analog Devices'
SHARC DSP processor.

Performance Density. The Company has been using high performance packaging
technology such as multi-chip modules and ball grid arrays in its systems since
the early 1990's. The Company's thermal analysis expertise allows it to design
products that optimize the dissipation of heat from the system in order to meet
the environmental constraints imposed by many of its customers' applications.
The Company's modular hardware and software building blocks allow it to design
systems that best meet the application's specific data profiles. All together,
these attributes combine to deliver the maximum performance in processing,
reliability and bandwidth in the smallest possible space.

Scalable Software. Mercury's software has been designed to scale to nearly
one thousand processors in real-time environments while maintaining a
high-bandwidth capability. Regardless of the number of processors, the Company's
software provides the same programming environment for a software developer
working with Mercury's computer systems, allowing faster time-to-market and
lower life cycle maintenance costs for its customers.

Optimized Algorithm Development. Mercury specializes in algorithm
development for single and multi-processor implementations. The Company believes
that using the mathematical algorithms in Mercury's scientific algorithm library
significantly increases the performance of customers' applications, reduces
development time and minimizes life cycle support costs.

System Engineering Expertise. Mercury has established a core competency in
providing total system solutions to its customers. The Company has the knowledge
and technical staff to act as an extension of the customer's engineering
organization in order to fashion solutions to some of the world's most demanding
real-time, signal processing applications. Mercury has partnered with its
customers to understand and resolve the challenging problems encountered in
applications as diverse as radar, sonar and signal intelligence for the
military, and diagnostic imaging for MRI, CT, PET and digital x-ray in the
medical imaging market. The Company also provides an integration and development
service to meet the demands of its customers with advanced applications that
cannot be satisfied with standard products. This service combines the variety of
standard products with custom hardware and software to meet the specific
configuration demands of an application.

Leverage and Create Standards. Mercury uses existing standards where
applicable and has been successful in developing new standards. For example,
Mercury adheres to VME and PCI standard bus interfaces and form factors. The
RACEway Interconnect system area network that Mercury developed was adopted as
an ANSI/VITA standard in 1995, and since then has been adopted by several
companies offering products and services for embedded real-time applications.

PRODUCTS

HARDWARE PRODUCTS

Mercury offers three classes of systems for the Company's target markets.
Each class of product is scalable to meet the full range of requirements in
signal processing applications.

High Performance Class. For the highest-performance applications, Mercury
offers a family of high performance systems for the most compute intensive, I/O
capacity and interprocessor bandwidth demanding applications in the defense
electronics market. These applications include space time adaptive processing,
ground-penetrating and foliage-penetrating radar and synthetic aperture radar.
These high-performance systems, known as MultiPort(TM) and PowerStream(TM), can
scale to a thousand processors and today include compute modules based on the
PowerPC processors.

VME Class. The VME bus has been the traditional standard for many embedded
applications. Mercury's VME systems each support RACEway Interconnect. Systems
contain modules based on the PowerPC and i860 processors and can scale to
several hundred processors. The VME-based systems and components are primarily
used in the defense market where backward and forward compatibility is required
for the long system life cycles of military equipment. This class of RACE
Series, and RACE++ Series systems meets the computing speed, bandwidth and
scaleability requirements of many of today's medium performance radar, sonar and
signal intelligence applications. Advanced and future radar systems are more
likely to use the high performance class systems.

Industrial PC Class. Based on the PCI bus standard, these systems use the
RACEway Interconnect to provide the extended bandwidth required for real-time
applications. Currently, Mercury provides compute modules based on the PowerPC
processors. The VantageRT(TM) systems scale to hundreds of processors and are
directed to the medical imaging and commercial OEM solutions markets, which are
moving from VME to PCI based designs.

SOFTWARE PRODUCTS

Mercury has developed a comprehensive line of signal processing software
products for the defense, medical imaging, and other commercial markets. Certain
of Mercury's software products are included in a heterogeneous development
software package that enables customers to develop application software that
will run on Mercury hardware. The development software package includes the
MC/OS operating system, scientific algorithm libraries, debugging tools and
compilers. License fees range from $10,000 to $50,000 based on the number of
seats chosen by the user for its application, ranging from a single user license
to a project license.

Set forth below are certain signal processing software products offered by
the Company.

MC/OS Run-Time Environment. The MC/OS runtime operating environment allows
maximum use of the RACE heterogeneous multi-computer architecture in a
single-system model incorporating a consistent set of system and application
programming interfaces, and a common development environment. MC/OS is supported
on the high performance, VME and industrial PC classes of Mercury hardware
systems. MC/OS is included in Mercury's development software package.

Scientific Algorithm Library (SAL). SAL comprises more than 400 assembly
language routines optimized for specific target processors including Motorola's
PowerPC 7400 with AltiVec technology. These SAL routines include functions for
vector processing, FFTs, and data conversion.

Vector Signal and Image Processing Library (VSIPL). A subset of the SAL
library has been restructured to conform to the VSIPL Standard. VSIPL-Lite
implements the VSIPL Core Lite function profile of the standard, which contains
the 125 most common functions for real-time signal processing. With a
performance that nearly equals SAL, VSIPL-Lite is a prime example of how Mercury
maintains a focus on performance while achieving portability through standards.

Parallel Application System (PAS). PAS is a set of high performance
libraries which form a complete programming environment for developing parallel
applications in a distributed memory multicomputer system. The libraries speed
the development of advanced applications using many processors in parallel. PAS
is included in Mercury's development software package.

RACE++(TM) Series MULTI(R) Integrated Development Environment (IDE). The
RACE++ Series MULTI IDE brings mainstream software development tools to the
challenge of developing real-time multicomputing solutions. With the MULTI IDE,
developers can create real-time multiprocessing routines using familiar,
industry-leading, graphical tools from Green Hills Software, the leader in
embedded mainstream software development tools and languages. The MULTI IDE
features integrated tools including the Language-Sensitive Text Editor, Project
Builder, and Source-Level Debugger, and supports open standards including
ELF/DWARF, ANSI C and C++, and PowerPC EABI.

TATL(TM) Trace Analysis Tool and Library. TATL is a system-level performance
analyzer and debugger that provides insight into complex multiprocessor
interactions in real-time systems. TATL works through the use of a low-overhead
event logging library during runtime and a powerful visualization tool for
off-line analysis of the dynamic communications, control, and dependencies in
the system. Because TATL is both powerful and easy to use, there is a very short
"time to insight."

ENGINEERING, RESEARCH AND DEVELOPMENT

The Company's engineering, research and development efforts are focused on
developing new products as well as enhancing existing products. Mercury's
research and development goal is to fully exploit and maintain the Company's
technological lead in the high performance, real-time, signal processing
industry.

Mercury is involved with researchers from other companies and government
organizations to develop new signaling technologies using fiber optics. This has
the potential for providing more bandwidth per line than conventional techniques
and is directed at the 21st century challenges of the next generation of
advanced signal processing systems. Similar cooperative developments are
underway to develop open software solutions for code portability. This research
is focused on developing generic applications, which can be targeted to
Mercury's products through the use of industry standard tools with
Mercury-specific libraries. Some of these research areas benefit from cost
sharing through Defense Advanced Research Projects Agency (DARPA) grants in
those areas where the DOD will obtain benefit from the development.

As of June 30, 2001, the Company had 206 people primarily engaged in
engineering, research and development, including hardware and software
architects, design engineers and engineers with expertise in developing medical,
defense and other commercial software systems. During fiscal years 2001, 2000
and 1999, the Company's total research and development costs were approximately
$30.5 million, $28.9 million, and $20.7 million, respectively.

CUSTOMER SUPPORT AND INTEGRATION

Mercury's Customer Services Group is engaged in a full range of support
functions, including training, technical program management, integration and
design services, host porting services and traditional maintenance and support
services. The Company has invested in the range of tools, analyzers, simulators,
instruments and workstations to provide a rapid response to both development and
customer support requirements. Within the Customer Services Group, the solutions
systems department has developed many custom interfaces, reviewed customers'
designs, developed special hardware and software components and provided program
management on behalf of defense and medical customers. The capabilities of this
group enable the Company to respond to the demanding individuality of many
programs and have resulted in Mercury being selected for both development, high
volume production and deployed programs.

MANUFACTURING AND TESTING

Mercury's strengths include the design, development and testing of products
which meet the exacting technology and quality expectations of the Company's
defense electronics and medical imaging customers. Board assembly is outsourced
to a number of electronic contract manufacturers. The supplier typically inserts
most of the components into a printed circuit board, solders the connections,
conducts preliminary testing and returns the boards to Mercury. The Company
conducts final assembly, burn-in and system level testing.

Mercury utilizes Optimal Supply Chain Management to provide highly flexible
manufacturing solutions which can be tailored to the specific needs of the
Company's customers, while maintaining the highest level of quality and control
of product assembly. This standard is maintained through demanding Quality
Assurance and Reliability Programs, such as Statistical Process Control, which
are integrated throughout the manufacturing process.

The Company's outsourcing strategy provides maximum flexibility to respond
to customer requirements and schedule adjustments, with minimal asset investment
by Mercury. This outsourcing strategy also provides multiple sources of supply,
both to support the breadth and complexity of Mercury's product lines, as well
as to ensure continuity of supply. By outsourcing assembly to electronic
contract manufacturers, Mercury is able to focus its manufacturing efforts on
designing more reliable products, designing more efficient methods of building
its products, systems integration, testing and supply chain management.

Mercury's manufacturing approach is based on a highly integrated process
that takes a product from concept through production. All products are required
to meet specified standards of performance, quality, reliability and safety. The
Company manufactures both commercial and rugged versions of its computer
systems. Extensive testing is a fundamental part of the Company's process.
Computer Integrated Manufacturing, Concurrent Engineering, Material Requirements
Planning and Just-In-Time techniques are also integrated into manufacturing
operations as part of an on-time delivery philosophy. Mercury has been ISO 9001
certified since 1995.

COMPETITION

The markets for the Company's products are highly competitive and are
characterized by rapidly changing technology, frequent product performance
improvements and evolving industry standards. Competition typically occurs at
the design stage, where the customer evaluates alternative design approaches,
including those from internal development organizations. A design win usually
ensures a customer will purchase the product until their next generation system
is developed. Occasionally, the Company's computer systems compete with computer
systems from workstation vendors, all of whom have substantially greater
research and development resources, long term guaranteed supply capacity,
marketing and financial resources, manufacturing capability and customer support
organizations than those of the Company. The Company believes that its future
ability to compete effectively will depend, in part, upon its ability to
continue to improve product and process technologies and develop new
technologies in order to maintain the performance advantages of products and
processes relative to competitors, to adapt products and processes to
technological changes, to identify and adopt emerging industry standards and to
adapt to customer needs.

The principal bases for selection in sales of digital signal processing
systems to the defense electronics industry are performance (measured primarily
in terms of processing speed, I/O capacity and interprocessor bandwidth,
processing density per cubic foot, power consumption and heat dissipation),
systems engineering support, overall quality of products and associated
services, use of industry standards, ease of use and price. Competitors in the
defense electronics industry include a relatively small number of companies that
design, manufacture and market DSP board level products and in-house design
teams employed by prime defense contractors. In-house design efforts
historically have provided a significant amount of competition to the Company.
However, competition from in-house design teams has diminished in significance
in recent years due to the increasing use of COTS products and the trend toward
greater use of outsourcing. Despite this recent change, there can be no
assurance that in-house developments will not re-emerge as a major competitive
force in the future. Prime contractors are much larger than Mercury and have
substantially more resources to invest in research and development. Increased
use of in-house design teams by defense contractors in the future may have a
material adverse effect on the Company's business, financial condition and
results of operations.

In the medical imaging industry the principal bases for selection are
performance (measured primarily in terms of processing speed, I/O capacity and
interprocessor bandwidth and power consumption), price, systems engineering
support, overall quality of products and associated services, use of industry
standards and ease of use. Competitors in the medical imaging market include
in-house design teams, a small number of companies that design, manufacture and
market DSP board level products and workstation manufacturers. Workstations have
become a competitive factor primarily in the market for low-end MRI and CT
machines and, to date, have not been a significant factor in the
high-performance market, Mercury's primary focus. There can be no assurance that
workstation manufacturers will not attempt to penetrate the high-performance
market for medical imaging machines. Workstation manufacturers typically have
greater resources than Mercury and their entry into markets historically
targeted by Mercury may have a material adverse effect on the Company's
business, financial condition and results of operations.

Some of the Company's competitors have greater financial and other resources
than the Company, and the Company may be operating at a cost disadvantage
compared to manufacturers who have greater direct buying power from component
suppliers or who have lower cost structures. There can be no assurance that the
Company will be able to compete successfully in the future with any of these
sources of competition. In addition, there can be no assurance that competitive
pressures will not result in price erosion, reduced margins, loss of market
share or other factors, that could have a material adverse effect on the
Company's business, financial condition and results of operations.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

The Company relies on a combination of patent, copyright, trademark and
trade secret laws to establish and protect its rights in its products and
proprietary technology. In addition, the Company currently requires its
employees and consultants to enter into nondisclosure and assignment of
invention agreements to limit use of, access to and distribution of, proprietary
information. There can be no assurance that the Company's means of protecting
its proprietary rights in the U.S. or abroad will be adequate. The laws of some
foreign countries may not protect the Company's proprietary rights as fully or
in the same manner as do the laws of the U.S. Also, despite the steps taken by
the Company to protect its proprietary rights, it may be possible for
unauthorized third parties to copy or reverse engineer aspects of the Company's
products, develop similar technology independently or otherwise obtain and use
information that the Company regards as proprietary. There can be no assurance
that others will not develop technologies similar or superior to the Company's
technology or design around the proprietary rights owned by the Company.
Although the Company is not aware that its products infringe on the proprietary
rights of third parties, there can be no assurance that others will not assert
claims of infringement in the future or that, if made, such claims will not be
successful. Litigation to determine the validity of any claims, whether or not
such litigation is determined in favor of the Company, could result in
significant expense to the Company and divert the efforts of the Company's
technical and management personnel from daily operations. In the event of any
adverse ruling in any litigation regarding intellectual property, the Company
may be required to pay substantial damages, discontinue the sale of infringing
products, expend significant resources to develop non-infringing technology or
obtain licenses to use infringing or substituted technology. The failure to
develop, or license on acceptable terms, a substitute technology could have a
material adverse effect on the Company's business, financial condition and
results of operations.

The Company holds five issued United States patents covering aspects of the
RACE architecture. The Company may file additional patent applications seeking
protection for other proprietary aspects of its technology in the future. Patent
positions frequently are uncertain and involve complex and evolving legal and
factual questions. The coverage sought in a patent application either can be
denied or significantly reduced before or after the patent is issued.
Consequently, there can be no assurance that any patents from pending patent
applications or from any future patent application will be issued, that the
scope of any patent protection will exclude competitors or provide competitive
advantages to the Company, that any of the Company's patents will be held valid
if subsequently challenged or that others will not claim rights in or ownership
of the patents and other proprietary rights held by the Company. Since patent
applications are secret until patents are issued in the United States or
corresponding applications are published in other countries, and since
publication of discoveries in the scientific or patent literature often lags
behind actual discoveries, the Company cannot be certain that it was the first
to make the inventions covered by each of its pending patent applications or
that it was the first to file patent applications for such inventions. In
addition, there can be no assurance that competitors, many of which have
substantial resources and have made substantial investments in competing
technologies, will not seek to apply for and obtain patents that will prevent,
limit or interfere with the Company's ability to make, use or sell its products
either in the United States or in international markets.


BACKLOG

As of June 30, 2001, the Company had a backlog of orders aggregating
approximately $39.4 million. The Company includes in its backlog, customer
orders for products and services for which it has accepted signed purchase
orders with assigned delivery dates within twelve months. Orders included in
backlog may be canceled or rescheduled by customers without penalty. A variety
of conditions, both specific to the individual customer and generally affecting
the customer's industry, may cause customers to cancel,


8
9

reduce or delay orders that were previously made or anticipated. The Company
cannot assure the timely replacement of canceled, delayed or reduced orders.
Significant or numerous cancellations, reductions or delays in orders by a
customer or group of customers could materially adversely affect the Company's
business, financial condition and results of operations. Backlog should not be
relied upon as indicative of the Company's revenues for any future period.

EMPLOYEES

At June 30, 2001, the Company employed a total of 542 persons, including 206
in research and development, 184 in sales, marketing and customer support, 62 in
manufacturing and 90 in general and administration. Fourteen of the Company's
employees are located in Europe, six in Japan and the remainder in the U.S. None
of the Company's employees are represented by a labor organization and the
Company believes that its relations with employees are good. Competition for
qualified personnel in the engineering fields is intense and the Company is
aware that much of its future success will depend on its continued ability to
attract and retain qualified personnel. The Company seeks to attract new
employees by offering competitive compensation packages, including salary,
bonus, stock options and employee benefits. There can be no assurance, however,
that the Company will be successful in retaining its key employees or that it
will be able to attract skilled personnel for the development of its business.

RISK FACTORS

In this report, as well as in oral statements made by the Company, that are
prefaced with the words "may," "will," "expect," "anticipate," "continue,"
"estimate," "project," "intend," "designed" and similar expressions, are
intended to identify forward-looking statements regarding events, conditions and
financial trends that may affect the Company's future plans of operations,
business strategy, results of operations and financial position. These
statements are based on the Company's current expectations and estimates as to
prospective events and circumstances about which the Company can give no firm
assurance. Further, any forward-looking statement speaks only as of the date on
which such statement is made, and the Company undertakes no obligation to update
any forward-looking statement to reflect events or circumstances after the date
on which such statement is made. As it is not possible to predict every new
factor that may emerge, forward-looking statements should not be relied upon as
a prediction of actual future financial condition or results. These
forward-looking statements, like any forward-looking statements, involve risks
and uncertainties that could cause actual results to differ materially from
those projected or anticipated. Such risks and uncertainties include the factors
set forth below.

DEPENDENCE ON DEFENSE ELECTRONICS BUSINESS; UNCERTAINTY ASSOCIATED WITH
GOVERNMENT CONTRACTS. Sales of the Company's computer systems to the defense
electronics market accounted for approximately 67%, 71%, and 77% of the
Company's revenues in fiscal 2001, 2000, and 1999, respectively. Reductions in
government spending on programs that incorporate the Company's products could
have a material adverse effect on the Company's business, financial condition
and results of operations. Moreover, the Company's government contracts and
subcontracts are subject to special risks, such as: delays in funding; ability
of the government agency to unilaterally terminate the prime contract; reduction
or modification in the event of changes in government policies or as the result
of budgetary constraints or political changes; increased or unexpected costs
under fixed price contracts; and other factors that are not under the control of
the Company. In addition, consolidation among defense industry contractors has
resulted in fewer contractors with increased bargaining power relative to the
Company. No assurance can be given that such increased bargaining power will not
adversely affect the Company's business, financial condition or results of
operations in the future.

The Company's contracts with the U.S. and foreign governments and their
prime and subcontractors are subject to termination either upon default by the
Company or at the convenience of the government. Termination for convenience
provisions generally entitle the Company to recover costs incurred, settlement
expenses and profit on work completed prior to termination. Because the Company
contracts to supply goods and services to U.S. and foreign governments it is
also subject to other risks, including contract suspensions, protests by
disappointed bidders of contract awards which can result in the reopening of the
bidding process, changes in governmental policies or regulations or other
political factors.

DEPENDENCE ON KEY CUSTOMERS. The Company is dependent on a small number of
customers for a large portion of its revenues. In fiscal 2001, Lockheed Martin,
Raytheon Systems Company, and GE Medical accounted for 18%, 14%, and 13%,
respectively, of the Company's revenues. In fiscal 2000, Raytheon Systems
Company, Lockheed Martin, Northrop Grumman Corporation and GE Medical accounted
for 19%, 14%, 12% and 12%, respectively, of the Company's revenues. In fiscal
1999, Raytheon Systems Company, Lockheed Martin, and GE Medical accounted for
22%, 16%, and 12%, respectively, of the Company's revenues. The Company's
largest customer in the medical imaging market, GE Medical, accounted for 52%,
59%, and 85% of the Company's aggregate sales to the medical imaging market in
fiscal 2001, 2000, and 1999, respectively. Customers in the defense electronics
market generally purchase the Company's products in connection with government
programs that have a limited duration, leading to fluctuating sales to any
particular customer in the defense electronics market from year to year. By
contrast, many customers in the medical imaging market historically have
purchased the Company's products over a number of years for use in successive
generations of medical imaging devices, although there can be no assurance that
such past behavior will continue in the

9
10

future. A significant diminution in the sales to or loss of any of the Company's
major customers would have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, the Company's
revenues are largely dependent upon the ability of its customers to develop and
sell products that incorporate the Company's products. No assurance can be given
that the Company's customers will not experience financial or other difficulties
that could adversely affect their operations and, in turn, the results of
operations of the Company.

FLUCTUATIONS IN OPERATING RESULTS. The Company has experienced fluctuations
in its results of operations in large part due to the sale by the Company of its
computer systems in relatively large dollar amounts to a relatively small number
of customers. Operating results also have fluctuated due to competitive pricing
programs and volume discounts, the loss of customers, market acceptance of the
Company's products, product obsolescence and general economic conditions. In
addition, the Company, from time to time, has entered into contracts to engineer
a specific solution based on modifications to the Company's standard products (a
"development contract"). The Company's gross margins from development contract
revenues are typically lower than the Company's gross margins from standard
product revenues. The Company intends to continue to enter into development
contracts and anticipates that the gross margins associated with development
contract revenues will continue to be lower than its gross margins on standard
product revenues. The Company expects research and development expenses to
continue to increase as the Company continues to develop products to serve its
markets, all of which are subject to rapidly changing technology, frequent
product performance improvements and evolving industry standards. The ability to
deliver superior technological performance on a timely and cost effective basis
is a critical factor in securing design wins for future generations of defense
electronics and medical imaging systems. Significant research and development
spending by the Company does not ensure that the Company's computer systems will
be designed into a customer's system. Because future production orders are
usually contingent upon securing a design win, the Company's operating results
may fluctuate due to either obtaining or failing to obtain design wins for
significant customer systems.

The Company's quarterly results may be subject to fluctuations resulting
from the foregoing factors, as well as from a number of other factors, including
the timing of significant orders, delays in completion of internal product
development projects, delays in shipping the Company's computer systems and
software programs, delays in acceptance testing by customers, a change in the
mix of products sold to the defense electronics and medical imaging markets,
production delays due to quality problems with outsourced components, shortages
of components, the timing of product line transitions and declines in quarterly
revenues from old generations of products following announcement of replacement
products containing more advanced technology. Another factor contributing to
fluctuations in quarterly results is the fixed nature of the Company's
expenditures on personnel, facilities and marketing programs. The Company's
expense levels for personnel, facilities and marketing programs are based, in
significant part, on the Company's expectations of future revenues on a
quarterly basis. If actual quarterly revenues are below management's
expectations, results of operations likely will be adversely affected. As a
result of the foregoing factors, the Company's operating results, from time to
time, may be below the expectations of public market analysts and investors,
which could have a material adverse effect on the price of the Company's Common
Stock.

DEPENDENCE ON SUPPLIERS. Several components used in the Company's products
are currently obtained from sole source suppliers. Mercury is dependent on key
vendors like LSI Logic, Atmel and Toshiba for custom designed ASICs, as well as
Motorola for many of its PowerPC line of processors. LSI may terminate their
contract with the Company without cause upon 30 days notice and may cease
offering products to the Company upon 180 days notice. If LSI Logic, Atmel,
Toshiba, or Motorola were to limit or reduce the sale of such components to the
Company, or if these or other suppliers to the Company were to experience
financial difficulties or other problems which prevented them from supplying the
Company with the necessary components, such events could have a material adverse
effect on the Company's business, financial condition and results of operations.
These sole source suppliers are subject to quality and performance issues,
materials shortages, excess demand, reduction in capacity and other factors that
may disrupt the flow of goods to the Company or its customers and thereby
adversely affect the Company's business and customer relationships. The Company
has no guaranteed supply arrangements with its suppliers and there can be no
assurance that its suppliers will continue to meet the Company's requirements.
If the Company's supply arrangements are interrupted, there can be no assurance
that the Company would be able to find another supplier on a timely or
satisfactory basis. Any shortage or interruption in the supply of any of the
components used in the Company's products, or the inability of the Company to
procure these components from alternate sources on acceptable terms could have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that severe shortages of
components will not occur in the future. Such shortages could increase the cost
or delay the shipment of the Company's products, which could have a material
adverse effect on the Company's business, financial condition and results of
operations. Significant increases in the prices of these components would also
materially adversely affect the Company's financial performance since the
Company may not be able to adjust product pricing to reflect the increase in
component costs. The Company could incur set-up costs and delays in
manufacturing should it become necessary to replace any key vendors due to work
stoppages, shipping delays, financial difficulties or other factors and, under
certain circumstances, these costs and delays could have a material adverse
effect on the Company's business, financial condition and results of operations.

DEPENDENCE UPON KEY PERSONNEL AND SKILLED EMPLOYEES. The Company is largely
dependent upon the skills and efforts of its senior management, particularly
James R. Bertelli, its President and Chief Executive Officer, as well as its
managerial, sales and technical employees. None of the senior management or
other key employees of the Company are subject to any


10
11

employment contract or noncompetition agreement. The Company maintains key-man
life insurance on Mr. Bertelli and certain other senior managers. The loss of
services of any of its executives or other key personnel could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company's future success will depend to a significant extent on
its ability to attract, train, motivate and retain highly skilled technical
professionals, particularly project managers, engineers and other senior
technical personnel. The Company believes that there is a shortage of, and
significant competition for, technical development professionals with the skills
and experience necessary to perform the services offered by the Company. The
Company's ability to maintain and renew existing engagements and obtain new
business depends, in large part, on its ability to hire and retain technical
personnel with the skills that keep pace with continuing changes in industry
standards, technologies and client preferences. The inability to hire additional
qualified personnel could impair the Company's ability to satisfy its growing
client base, requiring an increase in the level of responsibility for both
existing and new personnel. There can be no assurance that the Company will be
successful in retaining current or future employees.

DEPENDENCE ON MEDICAL IMAGING MARKET; POTENTIAL ADVERSE EFFECT OF HEALTH
CARE REFORM. Sales of the Company's computer systems to the medical imaging
market accounted for approximately 24%, 19%, and 14% of the Company's revenues
in fiscal 2001, 2000, and 1999, respectively. These customers are original
equipment manufacturers ("OEMs") of medical imaging devices and, as a result,
any change in the demand for such devices which renders any of the Company's
products unnecessary or obsolete, or any change in the technology in such
devices, could have a material adverse effect on the Company's business,
financial condition and results of operations. Such OEM customers, the end-users
of their products and the health care industry generally are subject to
extensive federal, state and local regulation in the U.S. as well as in other
countries. Changes in applicable health care laws and regulations or new
interpretations of existing laws and regulations could have a material adverse
effect on such customers or end-users. There can be no assurance that future
health care or budgetary legislation or other changes in the administration or
interpretation of governmental health care programs both in the U.S. and abroad
will not have a material adverse effect on the Company's business, financial
condition or results of operations.

RISK OF ENTRY INTO NEW MARKETS. The Company's expansion strategy includes
developing new products and entering new markets. The Company's ability to
compete in new markets will depend upon a number of factors including, without
limitation, the Company's ability to create demand for its products in such
markets, its ability to manage its growth effectively, the quality of its
products, its ability to respond to changes in its customers' businesses by
updating existing products and introducing, in a timely fashion, products which
meet the needs of its customers and the ability of the Company to respond
rapidly to technological change. The failure of the Company to do any of the
foregoing could result in a material adverse effect on its business, financial
condition and results of operations. In addition, the Company may face
competition in these new markets from various companies which may have
substantially greater research and development resources, marketing and
financial resources, manufacturing capability and customer support organizations
than those of the Company.

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS. The Company markets and
sells its products in certain international markets, and the Company has
established offices in the United Kingdom, Japan and France. Foreign revenue is
based on the country in which the legal subsidiary is domiciled. Foreign revenue
and long-lived assets represent less than 10% of the Company's total revenue and
total long-lived assets for the fiscal years ended June 30, 2001, 2000, and 1999
respectively. If revenues generated by foreign activities are not adequate to
offset the expense of establishing and maintaining these foreign subsidiaries
and activities, the Company's business, financial condition and results of
operations could be materially adversely affected. In addition, there are
certain risks inherent in transacting business internationally, such as changes
in applicable laws and regulatory requirements, export and import restrictions,
export controls relating to technology, tariffs and other trade barriers, less
favorable intellectual property laws, difficulties in staffing and managing
foreign operations, longer payment cycles, problems in collecting accounts
receivable, political instability, fluctuations in currency exchange rates,
expatriation controls and potential adverse tax consequences, any of which could
adversely impact the success of the Company's international activities. In the
recent past, the financial markets in Asia have experienced significant turmoil.
There can be no assurance that such turmoil in the Asian financial markets will
not negatively affect the sales by the Company to that region. A portion of the
Company's revenues from sales to foreign entities, including foreign
governments, is in the form of foreign currencies. There can be no assurance
that one or more of such factors will not have a material adverse effect on the
Company's future international activities and, consequently, on the Company's
business, financial condition or results of operations.

TECHNOLOGICAL CHANGES; RISK OF DESIGN-IN PROCESS. The Company's future
success will depend in part on its ability to enhance its current products and
to develop new products on a timely and cost-effective basis in order to respond
to technological developments and changing customer needs. The defense
electronics market, in particular, demands constant technological improvements
as a means of gaining military advantage. Military planners historically have
funded significantly more design projects than actual deployments of new
equipment, and those systems which are deployed tend to contain the components
of the subcontractors selected to participate in the design process. In order to
participate in the design of new defense electronics systems, the Company must
be able to demonstrate its ability to deliver superior technological performance
on a timely and cost-effective basis. There can be no assurance that the Company
will be able to secure an adequate number of defense electronics design wins in
the

11
12

future, that the equipment in which the Company's products are intended to
function eventually will be deployed in the field, or that the Company's
products will be included in such equipment if it eventually is deployed.

Customers in the medical imaging market also seek technological improvements
through product enhancements and new generations of products. The Company
believes that medical imaging machines in which the Company's computers are
installed have a long product life cycle. Medical equipment OEMs historically
have selected certain suppliers whose products have been included in the OEMs'
machines for a significant portion of the products' life cycle. There can be no
assurance that the Company will be selected to participate in the future design
of any medical imaging equipment, or that, if selected, the Company will
generate any revenues for such design work. Failure to participate in future
designs of medical imaging equipment could have a material adverse effect on the
Company's business, financial condition and results of operations.

The design-in process is typically lengthy and expensive, and there can be
no assurance that the Company will be able to continue to meet the product
specifications of its customers in a timely and adequate manner. In addition,
any failure by the Company to anticipate or respond adequately to changes in
technology and customer preferences, or any significant delay in product
developments or introductions, could have a material adverse effect on the
Company's business, financial condition and results of operations. Because of
the complexity of its products, the Company has experienced delays from time to
time in completing products on a timely basis. If the Company is unable to
design, develop or introduce competitive new products on a timely basis, its
future operating results would be adversely affected. There can be no assurance
that the Company will be successful in developing new products or enhancing its
existing products on a timely or cost-effective basis, or that such new products
or product enhancements will achieve market acceptance.

COMPETITION. The markets for the Company's products are highly competitive
and are characterized by rapidly changing technology, frequent product
performance improvements and evolving industry standards. See "Item 1. Business
- Competition."

LIMITED PROTECTION OF PROPRIETARY RIGHTS; POTENTIAL INFRINGEMENT OF THIRD
PARTY RIGHTS. There can be no assurance that the Company's means of protecting
its proprietary rights in the U.S. or abroad will be adequate, or that others
will not develop technologies similar or superior to the Company's technology or
design around the proprietary rights owned by the Company. In addition, there
can be no assurance that others will not assert claims of infringement in the
future or that, if made, such claims will not be successful. See "Item 1.
Business - Intellectual Property and Proprietary Rights."

POTENTIAL ACQUISITIONS. In the normal course of its business, the Company
evaluates potential acquisitions of businesses, products and technologies that
could complement or expand the Company's business. In the event the Company were
to identify an appropriate acquisition candidate, there is no assurance that the
Company would be able to successfully negotiate the terms of any such
acquisition, finance such acquisition and integrate such acquired business,
products or technologies into the Company's existing business and operations.
Furthermore, the integration of an acquired business could cause a diversion of
management time and resources. In addition, there can be no assurance that any
acquisition of new technology will lead to the successful development of new
products, or that any such new products, if developed, will achieve market
acceptance or prove to be profitable. There can be no assurance that a given
acquisition, when consummated, would not materially adversely affect the
Company's business, financial condition or results of operations. If the Company
proceeds with one or more significant acquisitions in which the consideration
consists of cash, a substantial portion of the Company's available cash could be
used to consummate the acquisitions. If the Company consummates one or more
significant acquisitions in which the consideration consists of stock, or is
financed with the net proceeds of the issuance of stock, stockholders of the
Company could suffer a significant dilution of their interests in the Company.

ITEM 2. PROPERTIES

The Company's headquarters consist of two buildings approximating 187,000
square feet of space in Chelmsford, Massachusetts. The Company purchased these
two buildings during fiscal 1999. In fiscal 2000, the Company purchased
approximately 179,000 square feet of land adjacent to the two existing lots. The
Company also maintains offices near Los Angeles and San Jose, California, and in
Dallas, Texas, Chanhassen, Minnesota, Madison, Wisconsin, Port St. Lucie,
Florida, Bellevue, Washington and Vienna, Virginia and has international offices
in the United Kingdom, France, the Netherlands and Japan.

ITEM 3. LEGAL PROCEEDINGS

In July 1999, a former employee brought a wrongful termination action
against the Company and certain officers of the Company. The plaintiff seeks
severance pay, the right to purchase 60,000 shares of the Company's common stock
at a price of $2.00 per share, the right to exercise 96,000 stock options at an
exercise price of $2.00 per share, and other financial consideration. Binding
arbitration has commenced but no ruling has been decided. The position of the
Company's management after consultation with external counsel, is that a loss
from this action is not probable. Accordingly, no loss accrual has been
recorded. If the plaintiff were to prevail on its claims, depending on the price
of the Company's common stock, a judgement for a material amount could be
awarded against the Company. The Company has objected to the claims and is
aggressively defending the matter.

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

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

In this report, as well as oral statements made by the Company, phrases that are
prefaced with the words "may," "will," "expect," "anticipate," "continue,"
"estimate," "project," "intend," "designed" and similar expressions, are
intended to identify forward-looking statements regarding events, conditions and
financial trends that may affect the Company's future plans of operations,
business strategy, results of operations and financial position. These
statements are based on the Company's current expectations and estimates as to
prospective events and circumstances about which the Company can give no firm
assurance. Further, any forward-looking statement speaks only as of the date on
which such statement is made, and the Company undertakes no obligation to update
any forward-looking statement to reflect events or circumstances after the date
on which such statement is made. As it is not possible to predict every new
factor that may emerge, forward-looking statements should not be relied upon as
a prediction of actual future financial condition or results. These
forward-looking statements, like any forward-looking statements, involve risks
and uncertainties that could cause actual results to differ materially from
those projected or anticipated. Such risks and uncertainties include certain
factors identified in the following discussion as well as the risk factors
reported in the Company's Form 10-K filed with the Securities and Exchange
Commission.

OVERVIEW

Mercury designs, manufactures and markets high performance, real-time digital
signal processing computer systems that transform sensor-generated data into
information which can be displayed as images for human interpretation or
subjected to additional computer analysis. These multicomputer systems are
heterogeneous and scalable, allowing them to accommodate several microprocessor
types and to scale from a few to hundreds of microprocessors within a single
system.

During the past several years, the majority of the Company's revenues has been
generated from sales of its products to the defense electronics market,
generally for use in intelligence gathering electronic warfare systems. The
Company's activities in this area have focused on the proof of concept,
development and deployment of advanced military applications in radar, sonar and
airborne surveillance. Medical diagnostic imaging is the other primary market
currently served by the Company. Mercury's computer systems are embedded in
Magnetic Resonance Imaging ("MRI"), Computed Tomography ("CT"), Positron
Emission Tomography ("PET"), and Digital Cardiology Imaging machines. The
remaining revenues are derived from computer systems used in such commercial
applications as baggage scanning, seismic analysis and automatic testing
equipment for the semiconductor industry.

Mercury uses a direct sales force to sell its computer systems to the defense
electronics markets in the U.S., Japan, and Europe. Defense electronics sales to
other countries are achieved through distributors. The Company also uses a
direct sales force to sell its computer systems to the U.S. and international
medical imaging markets. The Company sells its products to OEMs, value added
re-sellers and end-users. Over the past three fiscal years, the Company has
expanded its sales force to support growing revenues, made significant
expenditures to recruit additional technical and professional staff, invested in
information technology, and improved the Company's financial, administrative and
management infrastructure.

Revenues include hardware and software products, development contracts, services
such as maintenance, training, engineering consulting and system integration of
Mercury software with third-party hardware. Revenues from maintenance, training,
engineering consulting services and system integration historically have not
constituted a material portion of total revenues. Revenue related to products is
recognized upon shipment provided that title and risk of loss has passed to the
customer, there is persuasive evidence of an arrangement, the sales price is
fixed and determinable, collection of the related receivable is reasonably
assured and customer acceptance criteria have been successfully demonstrated.
The Company accrues for anticipated warranty costs upon shipment. Service
revenue is recognized ratably over applicable contract periods or as the
services are performed. For certain eligible contracts eligible under American
Institute of Certified Public Accountants ("AICPA") Statement of Position 81-1,
revenue is recognized using the percentage-of-completion accounting method based
on contract costs incurred to date compared with total estimated contract costs.
Changes to total estimated costs and anticipated losses, if any, are recognized
in the period in which determined.

Cost of revenues includes the cost of materials, component assembly, internal
labor and related overhead. Cost of revenues also can include engineering and
other technical labor and related overhead incurred in development and
engineering consulting contracts.

15

Gross profit as a percentage of revenues ("gross margin") varies from period to
period depending upon numerous variables including the mix of revenues from
hardware, software, development and engineering consulting contracts; the mix of
revenues among the markets served by the Company; the cost of raw materials; the
cost of outsourced services and labor; operational efficiencies; actual
production volume compared to planned volume; and the mix of applications for
which the Company's computer systems are sold. Historically, the Company's gross
margins on service revenues have been lower than on product revenues. In
addition, the Company's gross margins from development contract revenues are
typically lower than the Company's gross margins from standard product revenues.
The Company intends to continue to enter into development contracts and
anticipates that the gross margins associated with development contract revenues
will continue to be lower than its gross margins on standard product revenues.

Mercury has made significant investments in research and development in an
effort to maintain its technology leadership in digital signal processing.
Mercury invested $20.7 million, $28.9 million and $30.5 million in fiscal years
1999, 2000 and 2001, respectively, in development activities associated with the
Company's key technology competencies as well as in activities that are targeted
at developing new technologies and products. The Company expects research and
development expenses to continue to increase as the Company continues to develop
products to serve its markets, all of which are subject to rapidly changing
technology, frequent product performance improvements and evolving industry
standards. The ability to deliver superior technological performance on a timely
and cost-effective basis is a critical factor in securing design wins for future
generations of defense electronics, medical imaging systems, and other
commercial applications. Significant research and development spending by the
Company does not ensure that the Company's computer systems will be designed
into a customer's system. Because future production orders are usually
contingent upon securing a design win, the Company's operating results may
fluctuate due to either obtaining or failing to obtain design wins for
significant customer systems.

FISCAL 2000 VS. FISCAL 2001

REVENUES

Total revenues increased 28% from $140.9 million during the year ended June 30,
2000 to $180.5 million during the year ended June 30, 2001.

Defense electronics revenues increased 20% from $100.3 million or 71% of total
revenues during the year ended June 30, 2000 to $120.4 million or 67% of total
revenues during the year ended June 30, 2001. This increase in revenue was
primarily due to the increased unit demand for defense electronics products,
largely comprised of advanced military applications in radar and airborne
surveillance.

Medical imaging revenues increased 61% from $27.1 million or 19% of total
revenues during the year ended June 30, 2000 to $43.5 million or 24% of total
revenues during the year ended June 30, 2001. The increase in medical imaging
revenues reflects the increase in production volume of product for magnetic
resonance imaging ("MRI"), computed tomography ("CT"), and Positron Emission
Tomography ("PET") imaging systems, along with the first production shipments of
product for digital cardiology imaging systems.

Other commercial revenues increased 23% from $13.5 million or 10% of total
revenues during the year ended June 30, 2000 to $16.6 million or 9% of total
revenues during the year ended June 30, 2001. The increase in other commercial
revenues was due primarily to the expansion into existing markets, particularly
semiconductor photomask generation and mask inspection, offset in part by the
loss of the Shared Storage Business Unit ("SSBU") revenues.

16
17
COST OF REVENUES

Cost of revenues increased 53% from $39.1 million during the year ended June 30,
2000 to $59.8 million during the year ended June 30, 2001. Cost of revenues as a
percentage of total revenues increased from 28% during the year ended June 30,
2000 to 33% during the year ended June 30, 2001. The increase in costs as a
percentage of total revenues was primarily due to an increase in external
processing and component costs, a shift from higher margin defense products to
lower margin commercial products, and costs associated with re-establishing
certain discontinued standard parts.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expenses increased 28% from $39.5 million
during the year ended June 30, 2000 to $50.6 million during the year ended June
30, 2001. Selling, general and administrative expenses as a percentage of total
revenues were 28% for the years ended June 30, 2000 and 2001. The increase in
expenses year over year was primarily due to expenses associated with the
ongoing cost of implementing a new financial, manufacturing, and administrative
computer system. Additionally, commissions associated with higher sales volume
and the ongoing development of the Company's sales and management infrastructure
to support the Company's growth contributed to the increased expenses.

RESEARCH AND DEVELOPMENT

Research and development expenses increased 6% from $28.9 million during the
year ended June 30, 2000 to $30.5 million during the year ended June 30, 2001.
Research and development expenses as a percentage of total revenues were 20%
during the year ended June 30, 2000 and 17% during the year ended June 30, 2001.
The increase in research and development expenses was due primarily to the
hiring of additional software and hardware engineers to develop and enhance the
features and functionality of the Company's core products and a significant
investment in the research and development activities of the Wireless
Communications Group. Even with the increase in research and development
expenses as compared with a year ago, expenses are running lower than
management's expectations due to the delay in certain prototyping activities.

The Company's future success and ability to make the appropriate engineering
investments, will depend to a significant extent on its ability to attract,
train, motivate and retain highly skilled technical professionals, particularly
project managers, engineers and other senior technical personnel. The Company
believes that there is, from time to time, a shortage of, and significant
competition for, technical development professionals with the skills and
experience necessary to perform the services offered by the Company. The
Company's ability to maintain and renew existing engagements and obtain new
business depends, in large part, on its ability to hire and retain technical
personnel with the skills that keep pace with continuing changes in industry
standards, technologies and client preferences. The inability to hire additional
qualified personnel could impair the Company's ability to satisfy its growing
client base, requiring an increase in the level of responsibility for both
existing and new personnel. There can be no assurance that the Company will be
successful in retaining current or future employees and therefore able to
continue to make the investments in engineering at the projected higher
expenditure levels. Furthermore, the Company's inability to retain or hire
technical personnel may require contracting or outsourcing engineering
activities. This factor could result in higher than planned engineering expenses
and therefore, a possible fluctuation in the Company's operating results.

INCOME FROM OPERATIONS

Income from operations increased 18% from $33.5 million during the year ended
June 30, 2000 to $39.6 million during the year ended June 30, 2001. This
increase is associated with higher sales volume, offset in part by lower gross
margins.

Included in income from operations during the year ended June 30, 2000 were $1.8
million in hardware and software revenues and $2.4 million in direct expenses
related to SSBU. The direct expenses include expenses from marketing and
engineering activities, primarily related to compensation, trade shows,
prototype development and direct costs related to the sale of the product. SSBU
was sold in FY 2000.

GAIN ON SALE OF DIVISION

On January 18, 2000, the Company completed the sale of SSBU to International
Business Machines Corporation ("IBM"). Payments are structured with an initial
payment of $4.5 million (excluding $1.0 million to be held in escrow and payable
on a contingent basis), followed by 12 quarterly contingent payments of $1.5
million plus interest. The quarterly payments are contingent upon IBM's
continued use of the technology. If IBM defaults, Mercury has the right to
recover the assets, including the patent and other intellectual property. The
Company recorded $6.4 million and $4.8 million gains during the years ended June
30, 2001 and 2000, respectively. During the year ended June 30, 2000, the $4.8
million gain consisted of $6.1 million of cash received (initial $4.5 million
plus first quarterly payment of $1.6 million) less legal and advisory costs of
$581,000, compensation costs of $499,000, and net book value of equipment and
inventories sold of $200,000.

EQUITY LOSS IN JOINT VENTURE

In September 1999, the Company formed AgileVision as a joint venture with
Sarnoff Corporation, the developer of color television and a pioneer in the
creation of digital television ("DTV"). AgileVision provides broadcasters and
cable providers equipment to optimize their DTV investment and develop new
broadband media commerce revenue streams, including master control systems that

17
18

permit broadcasters to perform multiple functions on a single platform that
previously would have required the engineering and integration of numerous
discrete products and systems. The Company's investment in AgileVision during
the year ended June 30, 2000 and 2001 amounted to $3.5 million and $3.4 million,
respectively. The Company recognized $3.7 million and $3.3 million of losses on
the equity-basis of accounting related to the operations of AgileVision during
the years ended June 30, 2000 and 2001, respectively. On July 13, 2001, the
Company's board of directors approved an additional investment of up to $1
million for the purpose of continuing to fund the AgileVision operations.

INTEREST INCOME, NET

The Company earned $1.7 million in interest income, net, during the year ended
June 30, 2000 and $2.9 million during the year ended June 30, 2001. This
increase is primarily due to higher average cash balances offset in part by
lower interest rates.

PROVISION FOR INCOME TAXES

The Company's provision for income taxes was $11.4 million during the year ended
June 30, 2000 and $14.4 million during the year ended June 30, 2001. The
Company's effective tax rate was 31.5% during the year ended June 30, 2000 and
32.0% during the year ended June 30, 2001. The tax rates for both years ended
June 30, 2000 and 2001 were lower than the federal statutory rate of 35%
primarily due to the utilization of research and development credits and
tax-exempt interest income, offset partially by state income tax.

FISCAL 1999 VS. FISCAL 2000

REVENUES

Total revenues increased 32% from $106.6 million during the year ended June 30,
1999 to $140.9 million during the year ended June 30, 2000.

Defense electronics revenues increased 21% from $82.6 million or 77% of total
revenues during the year ended June 30, 1999 to $100.3 million or 71% of total
revenues during the year ended June 30, 2000. This increase in revenue was
primarily due to the increased unit demand for defense electronics products,
largely comprised of advanced military applications in radar, sonar, and
airborne surveillance.

Medical imaging revenues increased 77% from $15.3 million or 14% of total
revenues during the year ended June 30, 1999 to $27.1 million or 19% of total
revenues during the year ended June 30, 2000. The increase in medical imaging
revenues reflects the increase in production volume of product for our
customers' CT imaging systems.

Other revenues increased 55% from $8.7 million or 8% of total revenues during
the year ended June 30, 1999 to $13.5 million or 10% of total revenues during
the year ended June 30, 2000. The increase in other revenues was due primarily
to the addition of a new commercial customer, offset in part by the sale of SSBU
in January 2000.

COST OF REVENUES

Cost of revenues increased 14% from $34.2 million during the year ended June 30,
1999 to $39.1 million during the year ended June 30, 2000. Cost of revenues as a
percentage of total revenues decreased from 32% during the year ended June 30,
1999 to 28% during the year ended June 30, 2000. The decrease in costs as a
percentage of total revenues was primarily due to a decline in component costs
and tighter control over manufacturing spending.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expenses increased 20% from $33.0 million
during the year ended June 30, 1999 to $39.5 million during the year ended June
30, 2000. Selling, general and administrative expenses as a percentage of total
revenues were 31% during the year ended June 30, 1999 and 28% during the year
ended June 30, 2000. The increase in expense dollars reflects the hiring of
additional sales and administrative personnel, increased commissions related to
increased revenues, investment in an enterprise resource planning system, as
well as the ongoing development of the Company's financial, administrative and
management infrastructure to support the Company's growth.

RESEARCH AND DEVELOPMENT

Research and development expenses increased 39% from $20.7 million during the
year ended June 30, 1999 to $28.9 million during the year ended June 30, 2000.
Research and development expenses as a percentage of total revenues were 19%
during the year ended June 30, 1999 and 20% during the year ended June 30, 2000.
The increase in research and development expenses was due primarily to the
hiring of additional software and hardware engineers to develop and enhance the
features and functionality of the Company's products and an increased level of
introduction of new products in response to a high demand for next generation
products.

INCOME FROM OPERATIONS

Income from operations increased 80% from $18.6 million during the year ended
June 30, 1999 to $33.5 million during the year ended June 30, 2000. This
increase is associated with higher sales volume and lower cost of goods sold.

Included in income from operations during the year ended June 30, 2000 were $1.8
million in hardware and software revenues and $2.4 million in direct expenses
related to the SSBU. Included in income from operations during the year ended
June 30, 1999 were $2.2 million in hardware and software revenues and $4.0
million in direct expenses related to the SSBU. The direct expenses include
expenses from marketing and engineering activities, primarily related to
compensation, trade shows, prototype development and direct costs related to the
sale of the product.

GAIN ON SALE OF DIVISION

On January 18, 2000, the Company completed the sale of SSBU to IBM. Payments are
structured with an initial payment of $4.5 million (excluding $1.0 million to be
held in escrow and payable on a contingent basis), followed by 12 quarterly
contingent payments of $1.5 million plus interest. The quarterly payments are
contingent upon IBM's continued use of the technology. If IBM defaults, Mercury
has the right to recover the assets, including the patent and other intellectual
property. The Company recorded a $4.8 million gain on the sale of SSBU which
includes cash received of $6.1 million less legal and advisory costs of
$581,000, compensation costs of $499,000, and the net book value of equipment
and inventories sold of $200,000.

EQUITY LOSS IN JOINT VENTURE

discrete products and systems. During the year ended June 30, 2000, the
Company's contribution to AgileVision was $3.5 million in cash. During the year
ended June 30, 2000, the Company recognized $3.7 million of losses on the
equity-basis of accounting related to the operation of AgileVision. No expenses
were recognized during the year ended June 30, 1999.

INTEREST INCOME, NET

The Company earned $1.3 million in interest income, net, during the year ended
June 30, 1999 and $1.7 million during the year ended June 30, 2000. This
increase primarily reflects higher average cash balances.

PROVISION FOR INCOME TAXES

The Company's provision for income taxes was $6.6 million during the year ended
June 30, 1999 and $11.4 million during the year ended June 30, 2000. The
Company's effective tax rate was 33% during the year ended June 30, 1999 and
31.5% during the year ended June 30, 2000. During fiscal 2000, the tax rate was
reduced primarily due to a reduction in state taxes.

LIQUIDITY AND CAPITAL RESOURCES

As of June 30, 2001, the Company had cash and marketable securities of
approximately $95.6 million. During the year ended June 30, 2001, the Company
generated approximately $26.1 million in cash from operations compared to $30.7
million generated during the year ended June 30, 2000. The decrease in cash
generated from operations is attributable primarily to the Company's increase in
current assets, particularly trade receivables. Trade receivables increased
significantly at June 30, 2001 due to a large percentage of the fourth quarter
shipments delivered during the last few weeks of the year. Overall, the
Company's days sales, based on revenues of each calendar quarter, decreased from
70 days at the end of 2000 to 64 days at the end of 2001.

In September 1999, the Company formed AgileVision as a joint venture with
Sarnoff Corporation, the developer of color television and a pioneer in the
creation of digital television ("DTV"). AgileVision provides broadcasters and
cable providers equipment to optimize their DTV investment and develop new
broadband media commerce revenue streams, including master control systems that
permit broadcasters to perform multiple functions on a single platform that
previously would have required the engineering and integration of numerous
discrete products and systems. The Company's investment in AgileVision during
the year ended June 30, 2001 and 2000 amounted to $3.4 million and $3.5 million,
respectively. On July 13, 2001, the Company's board of directors approved an
additional investment of up to $1 million for the purpose of continuing to fund
the AgileVision operations.

The Company used approximately $21.8 million in investing activities during the
year ended June 30, 2001 compared to $45.9 million during the year ended June
30, 2000. During the year ended June 30, 2001, the Company's investing
activities consisted of $19.1 million for the purchase of marketable securities
(net of sales), $1.7 million of cash investment in AgileVision, and $7.4 million
for computers, furniture and equipment. These payments were partially offset by
the receipt of $6.4 million from the sale of a division. During the year ended
June 30, 2000, the Company's investing activities consisted of $40.8 million for
the purchase of marketable securities (net of sales), $3.5 million for
investment in AgileVision, $1.1 million for the purchase of land adjacent to its
existing headquarters and $5.5 million for computers, furniture and equipment.
These payments were partially offset by the receipt of $5.0 million from the
sale of a division.

19
20

The Company generated approximately $3.1 million in cash from financing
activities during the year ended June 30, 2001 compared to $17.4 million during
the year ended June 30, 2000. During the year ended June 30, 2001, the Company's
financing activities consisted primarily of $4.3 million in cash generated from
the employee stock purchase plan and the exercise of stock options. These cash
inflows were partially offset by the payment of debt and capital lease
obligations amounting to approximately $1.2 million. During the year ended June
30, 2000 the Company's financing activities consisted primarily of $14.5 million
in proceeds received upon the issuance of two 7.3% senior secured financing
notes. These notes are due November 2014. In addition, $3.7 million in cash was
generated from the employee stock purchase plan and the exercise of stock
options. These cash inflows were partially offset by the payment of debt and
capital lease obligations amounting to approximately $828,000.

Management believes that the Company's available cash, marketable securities,
and cash generated from operations, will be sufficient to provide for the
Company's working capital and capital expenditure requirements for at least the
next twenty-four months. If the Company acquires one or more businesses or
products, the Company's capital requirements could increase substantially. In
the event of such an acquisition or in the event that unanticipated
circumstances arise which significantly increase the Company's capital
requirements, there can be no assurance that necessary additional capital will
be available on terms acceptable to the Company, if at all.

RECENT ACCOUNTING PRONOUNCEMENTS

In December 1999, the Securities and Exchange Commission issued Staff Accounting
Bulletin No 101 ("SAB 101"), "Revenue Recognition". SAB 101 summarizes the
staff's view in applying generally accepted accounting principles to revenue
recognition. The Company adopted SAB 101 in fiscal year 2001. The adoption did
not have a material affect on its financial statements.

The Company adopted SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" as amended by SFAS No. 137 and SFAS No. 138 in the first
fiscal quarter of 2001. SFAS No. 133 requires the Company to recognize all
derivatives on the balance sheet at fair value. Adoption of SFAS No. 133 did not
have an impact on the Company's financial position or results of operations.

In July 2001, the FASB issued SFAS No. 141, "Business Combinations" and SFAS No.
142, "Goodwill and Other Intangible Assets." SFAS No. 141 requires that all
business combinations be accounted for under the purchase method only and that
certain acquired intangible assets in a business combination be recognized as
assets apart from goodwill. SFAS No. 142 requires that ratable amortization of
goodwill be replaced with periodic tests of the goodwill's impairment and that
intangible assets other than goodwill be amortized over their useful lives. SFAS
No. 141 is effective for all business combinations initiated after June 30, 2001
and for all business combinations accounted for by the purchase method for which
the date of acquisition is after June 30, 2001. The provisions of SFAS No. 142
are required to be adopted for fiscal years beginning after December 15, 2001,
however, the Company has, as permitted, adopted SFAS No. 142 early, as of July
1, 2001. The adoption of SFAS No. 142 had no impact on the Company's financial
position or results of operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK MANAGEMENT

Due to the short-term duration, the fair value of the Company's cash and
investment portfolio at June 30, 2001 approximated carrying value. Interest rate
risk is estimated as the potential decrease in fair value resulting from a
hypothetical 10% increase in interest rates for issues contained in the
investment portfolio. The resulting hypothetical fair value was not materially
different from the year-end carrying value.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(TABLES IN THOUSANDS EXCEPT FOR SHARE AND PER SHARE DATA)


A. DESCRIPTION OF BUSINESS:

Mercury Computer Systems, Inc. (the "Company") designs, manufactures and markets
high-performance real-time digital signal processing computer systems, which
transform sensor-generated data into information that can be displayed as images
for human interpretation or subjected to additional computer analysis. These
multicomputer systems are heterogeneous and scalable, allowing them to
accommodate several different microprocessor types and to scale from a few to
hundreds of microprocessors within a single system. The primary markets for the
Company's products are defense electronics, medical diagnostic imaging, and
other commercial applications. These markets have computing needs, which benefit
from the unique system architecture developed by the Company.

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF PRESENTATION

The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All significant intercompany transactions and
balances have been eliminated.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the dates of the financial statements and
the reported amounts of revenues and expenses during the reporting periods.
Actual results could differ from those estimates.

REVENUE RECOGNITION

Revenue related to products is recognized upon shipment provided that title and
risk of loss has passed to the customer, there is persuasive evidence of an
arrangement, the sales price is fixed and determinable, collection of the
related receivable is reasonably assured and customer acceptance criteria have
been successfully demonstrated. For products with acceptance criteria that are
not successfully demonstrated prior to shipment, revenue is recognized upon
customer acceptance. The Company accrues for anticipated warranty costs upon
shipment. Service revenue is recognized ratably over applicable contract periods
or as the services are performed.

For certain eligible contracts eligible under AICPA Statement of Position 81-1,
revenue is recognized using the percentage-of-completion accounting method based
on contract costs incurred to date compared with total estimated contract costs.
Changes to total estimated costs and anticipated losses, if any, are recognized
in the period in which determined. Approximately $1,789,000 of revenue was
recognized for the year ended June 30, 2001 under the percentage-of-completion
method, and no revenue was recognized for the year ended June 30, 2000 or 1999
under the percentage-of-completion method.

BILLINGS IN EXCESS OF REVENUES AND CUSTOMER ADVANCES

Billings in excess of revenues and customer advances include amounts billed on
uncompleted contracts and amounts billed on annual maintenance contracts.

CASH AND CASH EQUIVALENTS

Cash equivalents, consisting of money market funds and U.S. government and U.S.
government agency issues with original maturities of 90 days or less, are
carried at fair market value.

MARKETABLE SECURITIES

The Company classifies investments in marketable securities as either trading,
available-for-sale or held-to-maturity at the time of purchase and periodically
re-evaluates such classification. There were no securities classified as trading
or held-to-maturity as of June 30, 2001 and 2000. Securities are classified as
held-to-maturity when the Company has the positive intent and ability to hold
the securities to maturity. Held-to-maturity securities are stated at cost with
corresponding premiums or discounts amortized over the life of the investment to
interest income. Securities classified as available-for-sale are reported at
fair market value. Unrealized gains or losses on available-for-sale securities
are included, net of tax, in accumulated other comprehensive income until
disposition. Realized gains and losses and declines in value judged to be other
than temporary on available-for-sale securities are included in other income.
The cost of securities sold is based on the specific identification method.

The fair market value of cash equivalents and short-term and long-term
investments in marketable securities represents the quoted market prices at the
balance sheet dates. The short-term marketable securities have original
maturities greater than 90 days and remaining maturities less than one year.
Long-term marketable securities have remaining maturities greater than one


25
26


year. Long-term marketable securities have maturities of one to three years. At
June 30, 2001 and 2000, marketable securities were classified as follows:

<TABLE>
<CAPTION>
2001 2000
Available- Available-
For-Sale For-Sale
----------------------------
<S> <C> <C>
Short-term marketable securities:
Tax-exempt municipal notes and bonds and money market instruments $54,135 $36,784

Long-term marketable securities:
Tax exempt municipal notes and bonds, taxable corporate bonds,
government agencies $28,166 $25,705
</TABLE>

CONCENTRATION OF CREDIT RISK

Financial instruments that potentially expose the Company to concentrations of
credit risk consist principally of cash, marketable securities and trade
accounts receivable. The Company places its cash and cash equivalents with
financial institutions which management believes are of high credit quality. At
June 30, 2001 and 2000, the Company had approximately $5,613,000 and $3,088,000,
respectively, on deposit or invested with its primary financial and lending
institution.

At June 30, 2001 and 2000, only one customer comprised 10% or more of the
Company's receivables. Customer "A" represented 25% of the Company's receivables
at June 30, 2001 and 2000.

INVENTORY

Inventory is stated at the lower of cost, determined on the first-in, first-out
(FIFO) basis, or market.

PROPERTY AND EQUIPMENT

Property and equipment are recorded at cost. Equipment under capital lease is
recorded at the present value of the minimum lease payments required during the
lease period. Depreciation is based on the following estimated useful lives of
the assets using the straight-line method:


Computer equipment 3 years
Machinery and equipment 5 years
Furniture and fixtures 5 years
Buildings 15 - 30 years
Building improvements 10 years
Leasehold improvements Shorter of the lease term or economic life

Expenditures for additions, renewals and betterment of property and equipment
are capitalized. Expenditures for repairs and maintenance are charged to expense
as incurred. As assets are retired or sold, the related cost and accumulated
depreciation are removed from the accounts and any resulting gain or loss is
included in the results of operations.

CAPITALIZED SOFTWARE DEVELOPMENT COSTS

The Company capitalizes software development costs incurred after a product's
technological feasibility has been established and before it is available for
general release to customers. Amortization of capitalized software costs is
computed on an individual product basis and is the greater of a) the ratio that
current gross revenues for a product bear to the total of current and
anticipated future gross revenues for that product or b) the straight-line
method over the estimated economic life of the product. The Company uses an
estimated life of 2 years or less for all capitalized software costs.

RESEARCH AND DEVELOPMENT COSTS

Research and development costs are expensed as incurred.

INCOME TAXES

The Company recognizes deferred tax assets and liabilities for the expected
future tax consequences of events that have been included in the Company's
consolidated financial statements. Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax basis of assets and liabilities using currently enacted tax
rates for the year in which the differences are expected to reverse. The Company
records a valuation allowance against net deferred tax assets if, based upon the
available evidence, it is more likely than not that some or all of the deferred
tax assets will not be realized.

26
27


NET INCOME PER COMMON SHARE

The Company previously adopted SFAS No. 128, "Earnings per Share" (Statement
128). Statement 128 specifies the calculation and presentation of basic and
diluted net income per share. Basic net income per common share is calculated by
dividing net income by the weighted average number of common shares outstanding
during the period. Diluted net income per common share is calculated by dividing
net income by the sum of the weighted average number of common shares plus
additional common shares that would have been outstanding if potential dilutive
common shares had been issued for granted stock options.

FOREIGN CURRENCY

The accounts of foreign subsidiaries are translated using exchange rates in
effect at period-end for assets and liabilities and at average exchange rates
during the period for results of operations. Euros are used as the functional
currency for subsidiaries in France and the Netherlands, while local currency is
used as functional currency in the United Kingdom and Japan. The related
translation adjustments are reported in accumulated other comprehensive income
in stockholders' equity. Gains (losses) resulting from foreign currency
transactions are included in other income (expense) and are immaterial for all
periods presented.

RECLASSIFICATION

Certain reclassifications have been made to the prior years' financial
statements to conform to the current year's presentation.

NEW ACCOUNTING PRONOUNCEMENTS

In December 1999, the Securities and Exchange Commission issued Staff Accounting
Bulletin No 101 ("SAB 101"), "Revenue Recognition". SAB 101 summarizes the
staff's view in applying generally accepted accounting principles to revenue
recognition. The Company adopted SAB 101 in fiscal year 2001. The adoption did
not have a material affect on its financial statements.

The Company adopted SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" as amended by SFAS No. 137 and SFAS No. 138 in the first
fiscal quarter of 2001. SFAS No. 133 requires the Company to recognize all
derivatives on the balance sheet at fair value. Adoption of SFAS No. 133 did not
have an impact on the Company's financial position or results of operations.

In July 2001, the FASB issued SFAS No. 141, "Business Combinations" and SFAS No.
142, "Goodwill and Other Intangible Assets." SFAS No. 141 requires that all
business combinations be accounted for under the purchase method only and that
certain acquired intangible assets in a business combination be recognized as
assets apart from goodwill. SFAS No. 142 requires that ratable amortization of
goodwill be replaced with periodic tests of the goodwill's impairment and that
intangible assets other than goodwill be amortized over their useful lives. SFAS
No. 141 is effective for all business combinations initiated after June 30, 2001
and for all business combinations accounted for by the purchase method for which
the date of acquisition is after June 30, 2001. The provisions of SFAS No. 142
are required to be adopted for fiscal years beginning after December 15, 2001,
however, the Company has adopted SFAS No. 142 early, as of July 1, 2001. The
adoption of SFAS No. 142 had no impact on the Company's financial position or
results of operations.

C. NET INCOME PER COMMON SHARE:

The following table sets forth the computation of basic and diluted net income
per common share:

Options to purchase 110,538 shares of common stock in 2001, 141,000 shares in
2000, and 222,000 in 1999 were outstanding during the years then ended, but were
not included in the year-to-date calculation of diluted net income per share
because the options' exercise price was greater than the average market price of
the common shares during those periods.

On November 3, 1999, the Company completed a lending agreement with a commercial
financing company, issuing two 7.30% senior secured financing notes ("the
Notes"), due November 2014. The original principal value of the Notes amounted
to $14,500,000. The Notes are collateralized by the company's corporate
headquarters which consists of two buildings. The Notes' agreements contain
certain covenants, which, among other provisions, require the Company to
maintain a minimum net worth. As of June 30, 2001, the Company was in compliance
with the covenants of the Notes' agreements.

Maturities of long term debt are as follows:

LEGAL

In July 1999, a former employee brought a wrongful termination action against
the Company and certain officers of the Company. The plaintiff seeks severance
pay, the right to purchase 60,000 shares of the Company's common stock at a
price of $2.00 per share, the right to exercise 96,000 stock options at an
exercise price of $2.00 per share, and other financial consideration. Binding
arbitration has commenced but no ruling has been decided. The position of the
Company's management after consultation with external counsel, is that a loss
from this action is not probable. Accordingly, no loss accrual has been
recorded. If the plaintiff were to prevail on its claims, depending on the price
of the Company's common stock, a judgement for a material amount could be
awarded against the Company. The Company has objected to the claims and is
aggressively defending the matter.

LEASE COMMITMENTS

The Company leases certain facilities, machinery and equipment under capital and
operating leases expiring in various years through 2004 and thereafter. The
leases contain various renewal options. Rental charges are subject to escalation
for increases in certain operating costs of the lessor.

Minimum lease payments under operating and capital leases are as follows:

approximately $506,000, $524,000 and $1,116,000, respectively.

G. STOCKHOLDERS' EQUITY:

The Company is authorized to issue 1,000,000 shares of preferred stock with a
par value of $.01 per share.

COMMON STOCK

On November 18, 1999, the Company's Board of Directors authorized a two-for-one
stock split effected in the form of a 100% stock dividend distributed on
December 21, 1999 to shareholders of record as of December 6, 1999. As a result
of the stock split, the accompanying consolidated financial statements reflect
an increase in the number of outstanding shares of common stock and the transfer
of the par value of these additional shares from paid-in capital. All share and
per share amounts have been restated to reflect the retroactive effect of the
stock split, except the capitalization of the Company.

H. STOCK BASED COMPENSATION:

At June 30, 2001, the Company had both stock option plans and a stock purchase
plan. The Company has adopted SFAS No. 123, "Accounting for Stock-Based
Compensation" SFAS No. 123 requires that companies either recognize compensation
expense for grants of stock, stock options and other equity instruments based on
fair value or provide pro forma disclosure of net income and earnings per share
in the notes to the financial statements. The Company adopted the disclosure
provisions of SFAS No. 123 and has applied APB Opinion No. 25 and related
interpretations in accounting for all of its stock option and employee stock
purchase plans. Compensation cost is measured as the excess, if any, of the fair
market value of the Company's stock at the date of grant over the amount an
individual must pay to acquire the stock. Compensation expense recognized for
stock based compensation amounted to $411,000, $424,000, and $46,000 for the
fiscal years ended June 30, 2001, 2000, and 1999, respectively.

STOCK OPTION PLANS

The Company has five stock option plans. The 1982, 1991, and 1993 Stock Option
Plans (the "Plans") provide for the granting of options to purchase an aggregate
of not more than 1,950,000 shares of the Company's common stock to employees and
directors. Under these plans, options are granted at not less than the fair
value of the stock on the date of grant as determined by the Board. The terms of
the options are established by the Board on an individual basis. The options
generally vest between three and five years and have a maximum term of ten
years.

The 1997 Stock Option Plan (the "1997 Plan"), which the Board approved in June
1997, provides for the granting of options to purchase an aggregate of not more
than 2,650,000 shares, adjusted for a two-for-one stock split, of the Company's
common stock. The Plan provides for the grant of non-qualified and incentive
stock options to employees. Incentive stock options are granted at a price set
by the Board of Directors not to be less than 100% of the fair value at the date
of the grant. Non-qualified stock options are granted at not less than 50% of
the fair value of the stock on the date of grant as determined by the Board. The
options vest over five years and have a maximum term of ten years. In 1999, an
amendment to the plan was adopted by the Board of Directors of the Corporation,
which provided for an increase in the number of shares reserved for issuance
under the Plan from 2,650,000 shares, adjusted for a two-for-one stock split, of
common Stock to 4,650,000 shares, adjusted for a two-for-one stock split, and a
reduction in the vesting period for future options from five to four years. With
the implementation of the

29
30

1997 Plan, no further stock options were granted under the 1982 and 1991 Stock
Option Plans.

The 1998 Stock Option Plan (the "1998 Plan"), which the Board approved in
September 1998, provides for the granting of options to purchase an aggregate of
not more than 100,000 shares, adjusted for a two-for-one stock split, of the
Company's common stock. The Plan provides for the grant of non-qualified stock
options to non-employee directors. Non-qualified stock options are granted at
fair value of the stock at the date of the grant as determined by the Board of
Directors. The options vest over three years and have a maximum term of ten
years. With the implementation of the 1998 Plan, no further stock options were
granted under the 1993 Stock Option Plan. In August 2001, the 1998 Plan was
terminated.

There were 409,029 and 605,612 options exercisable at June 30, 2000 and 1999,
respectively, with weighted average exercise prices of $5.32 and $2.77. The fair
value of each option granted during fiscal years ended June 30, 2001, 2000 and
1999, is estimated on the date of grant using the Black-Scholes option-pricing
model utilizing the following weighted-average assumptions: (1) expected
risk-free interest rate of 4.97% in 2001, 6.34% in 2000 and 4.90% in 1999; (2)
expected option life of 6 years; (3) expected stock volatility of 80% for June
30, 2001, 77% for June 30, 2000 and 63% for June 30, 1999; and (4) expected
dividend yield of 0.0.%.

EMPLOYEE STOCK PURCHASE PLAN

During 1997, the Company adopted the 1997 Employee Stock Purchase Plan ("ESPP")
and authorized 500,000 shares, adjusted for a two-for-one stock split, for
future issuance under which rights are granted to purchase shares of common
stock at 85% of the lesser of the market value of such shares at either the
beginning or the end of each six-month offering period. The plan permits
employees to purchase common stock through payroll deductions, which may not
exceed 10% of an employee's

30
31

compensation as defined in the plan. During the two offerings in fiscal 2001,
the Company issued 16,949 and 14,115 shares of common stock to employees who
participated in the plan at prices of $27.04 and $34.85, respectively. Shares
available for future purchase under the ESPP totaled 373,697 at June 30, 2001.

The weighted-average fair value of purchase rights granted in fiscal 2001, 2000,
and 1999 was $13.52, $8.40, and $3.23, respectively. The fair value of the
employees' purchase rights was estimated using the Black-Scholes model with the
following assumptions: (1) dividend yield of 0.0%, (2) an expected life of six
months, (3) expected volatility of 80% for June 30, 2001, 77% for June 30, 2000,
and 63% for June 30, 1999; and , (4) risk-free interest rate of 3.63% for June
30, 2001, 5.25% for June 30, 2000, and 4.90% for June 30, 1999.

Had compensation cost for the Company's stock option grants and stock issued in
conjunction with the ESPP been determined based on the fair value at the grant
dates, as calculated in accordance with SFAS No. 123, the Company's net income
and net income per common share for the fiscal years ended June 30, 2001, 2000
and 1999, would approximate the following pro forma amounts as compared to the
amounts reported:

future amounts. SFAS No. 123 does not apply to awards prior to 1995 and
additional awards in future years are anticipated.

</TABLE>

No valuation allowance was deemed necessary for the deferred tax asset.
Management believes it is more likely than not that all of the deferred tax
asset will be realized.

At June 30, 2001, the Company had state research and development tax credit
carryforwards of approximately $1,247,000 which begin to expire in 2014.

J. EMPLOYEE BENEFIT PLANS:

The Company maintains a qualified 401(k) Plan and up until December 31, 1999,
maintained a qualified profit sharing 401(a) Plan. The 401(k) plan covers
employees who have attained the age of 21. Employee contributions to the 401(k)
Plan may range from 1% to 15% of compensation with a discretionary matching
Company contribution. Effective January 1, 2000, the Company began matching up
to 3% of compensation. Previously, the company matched up to 2% of compensation.
The Company may also make optional contributions to the plan for any plan year
at its discretion. The Company terminated its 401(a) Plan as of December 31,
1999.

Expense recognized by the Company under the 401(a) and 401(k) Plans was
approximately $1,048,000, $788,000 and $1,000,000 during the years ended June
30, 2001, 2000 and 1999, respectively.

The Company maintains a bonus plan, which provides cash awards to employees
based upon operating results and employee performance. Bonus expense to
employees was approximately $6,416,000, $4,499,000, and $2,753,000 during the
years ended June 30, 2001, 2000 and 1999, respectively.

K. OPERATING SEGMENT AND GEOGRAPHIC INFORMATION:

The Company adopted SFAS No. 131 "Disclosures about Segments of an Enterprise
and Related Information" (Statement No. 131), in fiscal 1999. This Statement
supersedes SFAS No. 14 "Financial Reporting for Segments of a Business
Enterprise," but retains the requirement to report information about major
customers. This statement establishes standards for reporting information about
operating segments in annual financial statements and requires selected
information about operating segments in interim financial reports issued to
stockholders. It also establishes standards for related disclosures about
products and services and geographic areas.

Operating segments are defined as components of an enterprise evaluated
regularly by the Company's senior management in deciding how to allocate
resources and in assessing performance. The Company has six principal operating
segments: North American Defense, Medical Imaging, Commercial, International
Defense and Commercial, Wireless Communications, and Research and Development.
These operating segments were determined based upon the nature of the products
offered to customers, the market characteristics of each operating segment, and
the Company's management structure. The Company has five reportable segments:
North American Defense, Medical Imaging segment, Commercial segment, Other
Defense and Commercial segment, and Research and Development segment. The Other
Defense and Commercial segment is comprised of International Defense, Wireless
Communications, and Other Commercial businesses unrelated to the defense or
medical businesses. These operating segments are not separately reported, as
they do not meet any of Statement No. 131's quantitative thresholds. A new
commercial operating segment was established during the first quarter of fiscal
2000. Previously, most commercial businesses were included within the North
American and International operating segments. Historical information was not
restated to reflect this business reorganization because it is impractical to
obtain the necessary information.

The accounting policies of the business segments are the same as those described
in "Note B: Summary of Significant Accounting Policies".

(1) Interest income, interest expense and foreign exchange gain/(loss) are
reported in Corporate and not allocated to the principal operating
segments. Only expenses directly related to an operating segment are
charged to the appropriate operating segment. All other expenses for
marketing and administrative support activities that cannot be specifically
identified with a principal operating segment are allocated to Corporate.

(2) The North American Defense and the Other Defense and Commercial segment
differ in definition from the defense market segment described in the
Company's management discussion and analysis ("MD&A"). The Defense market
segment in the MD&A refers to the worldwide defense market. The North
American Defense and the Other Defense and Commercial are operating
segments as defined by Statement No. 131, and are subsets of the worldwide
defense market discussed in the MD&A.

Foreign revenue is based on the country in which the legal subsidiary is
domiciled. Foreign revenue and long-lived assets represent less than 10% of the
Company's total revenue and total long-lived assets for the fiscal years ended
June 30, 2001, 2000 and 1999 respectively.

Customers comprising 10% or more of the Company's revenues for the periods shown
below are as follows:

YEAR ENDED JUNE 30, 2001 2000 1999

Customer E 18% 14% 16%
Customer B 14% 19% 22%
Customer D 13% 12% 12%
Customer A -- 12% --

L. SALE OF DIVISION:

On January 18, 2000, the Company completed the sale of the SSBU to IBM. Payments
are structured with an initial payment of $4,500,000 (excluding $1,000,000 to be
held in escrow and payable on a contingent basis), followed by 12 quarterly
contingent payments of $1,500,000 plus interest. The quarterly payments are
contingent upon IBM's continued use of the technology. If IBM defaults, Mercury
has the right to recover the assets, including the patent and other intellectual
property. The contingency payments of $1,500,000 per quarter are recognized when
collected. During the twelve month period ended June 30, 2001, the Company
recorded a $6,400,000 gain on the sale of this division. During the twelve
months ended June 30, 2000, the Company recorded a $4,820,000 gain on the sale
of this division which includes cash received of $6,100,000 less legal and
advisory costs of $581,000, costs reimbursable to IBM of $499,000, and the net
book value of equipment and inventories sold of $200,000.

M. EQUITY LOSS IN JOINT VENTURE:

In September 1999, the Company formed AgileVision as a joint venture with
Sarnoff Corporation, the developer of color television and a pioneer in the
creation of digital television ("DTV"). AgileVision provides broadcasters and
cable providers equipment to optimize their DTV investment and develop new
broadband media commerce revenue streams, including master control systems that
permit broadcasters to perform multiple functions on a single platform that
previously would have required the engineering and integration of numerous
discrete products and systems. The Company's investment in AgileVision


33
34

amounted to $3,400,000 and $3,500,000 during the years ended June 30, 2001 and
2000, respectively. The Company recognized $3,310,000 and $3,721,000 of losses
on the equity-basis of accounting related to the operations of AgileVision
during the years ended June 30, 2001 and 2000, respectively.
