ITEM 1. BUSINESS
 
STRUCTURE OF THE COMPANY
 
  Advanced Technology Laboratories, Inc. ("ATL" or the "Company") is engaged
in the high-technology medical systems business. ATL develops, manufactures,
markets and services diagnostic medical ultrasound systems and related
accessories and supplies worldwide. The Company currently operates through 13
international affiliates and through local distributors worldwide.
 
COMPANY HISTORY
 
  ATL was founded in 1969 and acquired by Squibb Corporation ("Squibb") in
1980. In 1982 Squibb acquired Advanced Diagnostic Research Corporation
("ADR"), a Tempe, Arizona company which was a leader in obstetrical and
abdominal ultrasound, and A.B. Kranzbuehler ("Kranzbuehler"), a European
ultrasound manufacturer and distributor of ADR products in Europe. In 1986
Squibb organized its medical equipment businesses, including SpaceLabs
Medical, Inc. ("SpaceLabs"), a manufacturer and supplier of patient monitoring
and clinical information systems, under a corporate holding company, Westmark
International Incorporated ("Westmark") and spun the companies off through a
distribution of Westmark common stock to Squibb shareholders on January 2,
1987. In 1992 Westmark shareholders voted to separate Westmark into two
publicly traded companies comprising two major operating subsidiaries, ATL and
SpaceLabs. Westmark shareholders received an equal number of shares of the new
separate public company, SpaceLabs, and Westmark changed its name to Advanced
Technology Laboratories, Inc., the same name as that of its remaining
operating subsidiary. ATL conducts a substantial portion of its business
through this domestic operating subsidiary, now known as ATL Ultrasound, Inc.
 
  In May 1994 the Company acquired Interspec, Inc. ("Interspec"), a developer
and manufacturer of medical diagnostic ultrasound systems and transducers
headquartered in Ambler, Pennsylvania through a stock for stock exchange that
was approved by the shareholders of both companies. This acquisition added the
Apogee(R) product lines of Interspec to those of ATL, giving the Company an
expanded presence in the mid-range price and cardiology ultrasound markets.
During 1995 the Company consolidated Interspec's Ambler, Pennsylvania
operations with ATL's worldwide headquarters operations in Bothell,
Washington. In 1995 the Company reincorporated in the state of Washington from
its original domicile in Delaware.
 
  In February 1997 the Company announced that it had entered into a memorandum
of understanding to sell its Nova MicroSonics division to the Eastman Kodak
Company ("Kodak"), which is establishing a worldwide presence in multi-
modality image management. ATL has been working cooperatively with Kodak for a
number of years in ultrasound image management product performance and
distribution. The Nova MicroSonics division manufactures and markets
networking, image acquisition and measurement products for use in ultrasound
data and image management by hospitals, labs, clinics and physician offices.
The Company expects to complete this transaction during the first half of
1997. After transfer of the division to Kodak, ATL will continue to work
closely with the Nova MicroSonics unit in the development and distribution of
image management products. The transaction is not expected to result in a
material gain or loss.
 
THE ULTRASOUND BUSINESS
 
  ATL develops, manufactures, markets and services diagnostic medical
ultrasound systems that are widely used in a number of medical applications to
assist the physician in monitoring and diagnosing a variety of conditions,
such as tumors, inflammations, obstructions, cardiovascular diseases, fetal
development, and surgical assessment. Ultrasound systems provide a safe,
noninvasive and painless means of observing soft tissues and internal body
organs and assessing blood flow through the heart and vessels. ATL is one of
the leading suppliers of diagnostic ultrasound systems in the world. Its High
Definition(TM) Imaging (HDI(R)) and Apogee product lines
 
                                       3
<PAGE>
 
serve all major diagnostic ultrasound clinical markets--radiology, cardiology,
obstetrics/gynecology ("OB/GYN") and vascular medicine--and a variety of newly
emerging clinical markets. These product lines span a range of system prices
from mid to premium priced ultrasound products.
 
  Diagnostic ultrasound products, upgrades and accessories sold for use in
hospitals, clinics and physicians' offices accounted for an estimated $2.3
billion worldwide market in 1996. The total medical imaging market, including
x-ray, MRI and CT imaging equipment is estimated by the Company to be over $8
billion worldwide in 1996.
 
ULTRASOUND TECHNOLOGY
 
 ATL's Technology
 
  The Company believes that it has become a worldwide leader in ultrasound
technology through its proprietary position in digital, broad bandwidth
beamforming, advanced software, and broad bandwidth scanhead technologies.
Ultrasound systems include three major components: a scanhead which transmits
sound waves into the body of a patient, receives returning echoes from the
patient and converts the echoes into electrical signals; a processing unit
which processes the electrical echo signals into images and measurements of
physiological conditions within the patient's body; and a monitor which
displays the resulting images or measurement information. ATL's scanheads are
characterized by the breadth of the bandwidth of ultrasonic signals which are
transmitted and received. ATL's HDI systems are characterized by their ability
to fully process broadband signals characteristic of the body's tissues
digitally. ATL has been a pioneer in digital ultrasound technology and
introduced the industry's first digital beamforming processor in 1988. In
February 1997 ATL introduced the HDI 1000 system, which combines ATL's core
technologies in broadband scanheads, digital beamforming, and advanced
proprietary software to form a software-based color system for the world's
rapidly growing mid-range markets.
 
ATL'S PRODUCTS
 
  HDI 3000 ULTRASOUND SYSTEM. In October 1994 ATL introduced its fourth
generation digital ultrasound system, the HDI 3000(TM) system. The HDI 3000
system is designed to address the economic imperatives of an evolving health
care environment in the United States and international markets. It is lighter
in weight than competitive premium systems, providing greater mobility and
enabling it to be easily moved to the bedside of critical care patients. The
HDI 3000 system also features an intuitive, ergonomically designed set of user
controls, which enable an ultrasonographer or physician to quickly gain
confidence in operating the system and performing highly diagnostic
examinations. The HDI 3000 system provides interactive menu screens with
diagnostic procedures selectable at the touch of a button. This feature,
called Tissue Specific(TM) Imaging, automatically optimizes over one thousand
system operating parameters for the selected diagnostic procedure and
scanhead. The HDI 3000 system offers full Doppler capability including Color
Power Angio(TM) imaging features, Power Motion Imaging(TM) for cardiac
applications, Contrast Specific Imaging(TM) for harmonic imaging and imaging
with ultrasonic contrast agents, and three dimensional imaging of the human
vasculature. The HDI 3000 system operates with a full array of broad bandwidth
scanheads, including a family of Entos intraoperative scanheads designed for
surgical use, the diagnosis of breast disease and musculoskeletal injuries.
 
  The HDI 3000 system can be purchased in a variety of configurations for
specific clinical applications, including a fully configured model for the
cardiovascular market, the HDI 3000cv system.
 
  In April, 1996 the U.S. Food and Drug Administration (FDA) approved ATL's
breast premarket approval application (PMA) for the HDI system. This approval
allows a new clinical application of ultrasound that, in conjunction with
mammography, will provide physicians with a high level of confidence in
differentiating benign from malignant or suspicious breast lesions. Studies
have shown that approximately 80% of breast lump biopsies performed in the
United States have resulted in a finding that the lump is benign. The PMA
application was
 
                                       4
<PAGE>
 
based on the results of an international multi-center study involving the
examination of women with indeterminate lesions with the Ultramark 9 HDI
system. In December, 1996 the FDA approved a PMA supplement which allows the
HDI 3000 system to be marketed for this new application. ATL has equipped the
HDI 3000 to perform examinations in accordance with the new protocol through
the introduction of a new breast analysis package for the system, which was
introduced in the fall of 1996.
 
  In October, 1996 ATL expanded the price and performance ranges of the HDI
3000 system by making the system available in both standard and advanced
configurations. The standard configuration provides all of the standard
grayscale, Doppler, colorflow and reporting capabilities of a premium
ultrasound system. The advanced configuration adds an expanded image memory,
Color Power Angio imaging features, Power Motion Imaging capability, three
dimensional Color Power Angio imaging, DiskLink and NetLink communication
functions, and Contrast Specific Imaging(TM) for imaging with ultrasonic
contrast agents. The standard configuration can be upgraded to any of these
advanced capabilities at a later date.
 
  New scanheads which became available during 1996 for the HDI 3000 system
included a pediatric biplane transesophageal echocardiography probe and a C8-5
pediatric neonatal probe. The new probes were complemented by a new pediatric
calculation software package for the system.
 
  HDI 1000 ULTRASOUND SYSTEM. In February 1997 ATL introduced the HDI 1000
system, a mid-range grayscale, color and Doppler product for the general
imaging and OB/GYN markets. This system makes many features of high
performance ultrasound systems affordable to a broad range of potential
customers through advanced software implementation: the system replaces over
50% of the hardware of a conventional ultrasound machine with software which
performs over 70% of the functions of the ultrasound system. At the heart of
this software-intensive system is ATL's proprietary Multitasking Software
Management technology (MSM(TM)), which utilizes an "object-oriented" software
architecture to perform self-contained software tasks which replace
conventional ultrasound hardware.
 
  The HDI 1000 system is also unique among mid-range ultrasound products for
its broad range of communication capabilities. The HDI 1000 system's MSM
technology comes equipped for remote Internet/Intranet access to images and
reports stored in the system's memory. ATL's proprietary WebLink(TM) feature
enables physicians to simultaneously view images on the system and consult
with colleagues around the globe directly from the HDI 1000 system. The system
can even be remotely controlled through secure Web pages transmitted over the
Internet. The fully integrated communication capabilities enable patient
reports and ultrasound images to be printed directly on standard desktop
printers.
 
  The HDI 1000 system utilizes scanheads of the other ATL HDI systems and the
ease of control of HDI Tissue Specific(TM) Imaging, enabling existing ATL
customers to apply their existing HDI scanheads and previously acquired
operating skills directly to the HDI 1000 system.
 
  APOGEE 800PLUS SYSTEM. In 1994 the Company introduced the mid-range Apogee
800 system for the mid-range radiology and internal medicine markets. The
Apogee 800 system offers features normally found on high performance systems
and can be configured to address the broad array of clinical needs of the
radiologist, internal medicine specialist, and OB/GYN physician. In March,
1996 ATL introduced an upgraded model of this product, the Apogee 800PLUS,
offering improved image quality, Doppler performance, processing capability,
improved analysis packages and user controls. In the fall of 1996 the Apogee
800PLUS system became available in a full cardiology configuration with the
introduction of three new convex phased array scanheads, the 4-2C15 adult
cardiology probe, the 6-3C13 small adult cardiology probe, and the 8-5C11
pediatric cardiology probe. Concurrently, the Company added integrated stress
echo capability to this cardiology product.
 
  In September, 1996 the Company announced that it had entered into a
technology transfer agreement with the Shantou Institute of Ultrasonic
Instruments (SIUI), whereby SIUI will manufacture Apogee 800PLUS
 
                                       5
<PAGE>
 
systems in the People's Republic of China. SIUI also acquired the exclusive
right to distribute the Apogee 800PLUS system in that country. ATL continues
to manufacture the Apogee 800PLUS system in Bothell, Washington for worldwide
distribution outside of China.
 
  IMAGE MANAGEMENT PRODUCTS. The Company's Nova MicroSonics division develops,
manufactures and markets a complete line of ultrasound image management
products for use in the digital acquisition, storage, display and management
of ultrasound information. These products provide efficient printing,
automated image archival and retrieval and reduced patient examination times
through an ultrasound open network architecture. The Access(TM) Image
Management System connects to many types of ultrasound systems, printers or
other image management products, facilitating improved diagnostic
consultations within and between hospitals.
 
  For cardiac applications, Nova MicroSonics offers products that facilitate
the review and comparison of images produced at different times during a
cardiac study, expanding the diagnostic applications of echocardiography to
the detection of coronary artery disease. The ImageVue/DCR Workstation is a
state-of-the-art digital ultrasound image management system. This workstation
performs analysis and review of ultrasound exams conducted from a variety of
ultrasound systems.
 
  The Image LAN Network provides network connection between ultrasound
systems, workstations, printers and other medical imaging devices and operates
with both the radiology and cardiology image management products.
 
  In February, 1997 the Company entered into a memorandum of understanding to
sell the Nova MicroSonics division to Kodak. After transfer of the division to
Kodak, ATL will continue to work closely with the Nova MicroSonics unit in the
development and distribution of image management products.
 
  SCANHEADS. ATL believes that its internal resources devoted to development
and manufacture of ultrasonic scanheads make it one of the largest ultrasound
scanhead manufacturers in the world. ATL's capabilities in scanhead design and
manufacture were enhanced in 1994 with the addition of the Echo Ultrasound
division of Interspec. The Echo Ultrasound division, located in Reedsville,
Pennsylvania, produces scanheads for ATL products and also offers scanheads to
other ultrasound companies.
 
  ACCESSORIES AND SUPPLIES. The Company sells a variety of ultrasound
accessories and supplies, most of which are not manufactured by the Company.
These include disposable supplies, such as ultrasound gel and thermal paper,
and accessories, such as biopsy guides, printers, cameras and videocassette
recorders ("VCRs"). The Company markets these products through direct sales
and mail and its customer support organization.
 
PRINCIPAL MARKETS
 
  The worldwide ultrasound market is typically categorized by clinical
application, price range and geographic area.
 
  CLINICAL APPLICATIONS. Ultrasound products are used in four primary medical
applications: radiology, cardiology, OB/GYN, and vascular applications. ATL
also sells its products in several emerging clinical application markets,
including breast and musculoskeletal applications and the surgical ultrasound
market.
 
  Radiology. The radiology, or general imaging, application, at approximately
48% of the worldwide ultrasound market, is the largest market for ultrasound
equipment. The major radiology markets are in the United States, Japan and
Europe. Most radiology examinations are conducted in hospitals or large
imaging centers.
 
  In radiology, ultrasound is used to obtain diagnostic information on organs
and soft tissue, particularly in the abdominal area. It is also used to
ascertain fetal development, to guide tissue biopsies and to visualize blood
flow.
 
 
                                       6
<PAGE>
 
  A substantial portion of the radiology market also requires systems which
include cardiac imaging capabilities. In the United States and Canada this
market segment is often referred to as the shared service market. Most
community or small hospitals without a dedicated cardiology department fall
into this category. In Europe, the internal medicine or shared services
segment requires systems which include cardiac imaging capability.
 
  ATL's radiology product offerings include the HDI 3000 system in both
standard and advanced configurations, the new HDI 1000 system, and the Apogee
800PLUS system.
 
  Cardiology. The cardiology ultrasound, or echocardiography, application, at
approximately 25%, is the second largest market for ultrasound systems. Most
dedicated echocardiography system sales occur in the United States, Western
Europe, and the more developed Asian and Latin American markets. While most
cardiology system sales are to hospitals, the cardiology office practice
represents a significant and growing share of the market for echocardiography
equipment.
 
  Cardiologists use ultrasound as a noninvasive means of capturing real-time
images of the heart and its valves. These images, together with various
Doppler techniques, help the physician assess heart function as well as
congenital and valvular disease. With new advances in scanheads plus
acquisition and image display technology, echocardiography is a useful tool
for the detection and assessment of coronary artery disease. Ultrasound has
also been shown to be valuable in assessing the effectiveness of drug therapy
and intervention for the heart attack patient.
 
  In 1996 ATL became the first ultrasound company to introduce the integrated
capability to image harmonic and other ultrasonic contrast agents in the HDI
3000cv system. It is anticipated that this emerging application will gain
increasing prominence as contrast agents become more widely available around
the world and cardiologists become more familiar with their application and
use.
 
  ATL's cardiology product offerings include the HDI 3000cv system and the
Apogee 800PLUS system.
 
  OB/GYN. The third largest market for ultrasound systems is the OB/GYN
application, at approximately 15%. The majority of OB/GYN ultrasound system
sales are to office-based practitioners in the United States, Western Europe,
and the more developed Asian markets. Perinatology is a clinical specialty in
OB/GYN dedicated to high risk obstetrics. Most perinatology ultrasound sales
are to hospitals and institutions in the United States. Ultrasound is the
preferred imaging technology for the assessment of fetal development since it
is noninvasive and involves no ionizing radiation. Ultrasound is also used for
general gynecological and infertility examinations. The introduction of the
intravaginal scanhead in the 1980s expanded the usefulness of ultrasound for
first-trimester obstetrical studies and the diagnosis of ectopic pregnancies.
 
  ATL's OB/GYN product offerings include the HDI 3000 system for perinatology,
and the new HDI 1000 system and the Apogee 800PLUS system for all OB/GYN
applications and markets.
 
  Vascular. The smallest of the primary clinical markets for ultrasound
systems, at approximately 4%, is the vascular ultrasound application,
primarily practiced in the United States and Western Europe. Most vascular
ultrasound examinations are performed in hospitals.
 
  Vascular ultrasound studies utilize real-time imaging, Doppler and color
Doppler information to identify plaque deposits and their characteristics,
clots, and valve competence in blood vessels. Most vascular examinations are
performed on the body's extremities, cerebrovascular and deep abdominal
regions.
 
  ATL's vascular product offerings include the HDI 3000 and the Apogee 800PLUS
systems. The Entos CL10-5 intraoperative scanhead was specially designed for
vascular surgery, and addresses the increasing use of ultrasound in the
surgical suite to immediately assess the results of surgical procedures.
 
 
                                       7
<PAGE>
 
  Emerging applications. Other specialized applications for ultrasound
products, such as breast disease, musculoskeletal, and surgery, account for
approximately 8% of the worldwide ultrasound market. ATL provides the HDI 3000
system with the L10-5 and Entos CL10-5 scanheads for breast clinics and
orthopedic and sports medicine clinics, and the HDI 3000 system with the Entos
CL10-5, CT8-4 and LI9-5 intraoperative scanheads for surgical suites. The HDI
3000 is available with a laparoscopic probe for minimally invasive surgery,
and with harmonic and contrast agent imaging capability for emerging
applications of contrast agents in both radiology and cardiology.
 
  PRICE RANGES. The world ultrasound market can be divided into five segments
based on broad price ranges. Each market segment is characterized by the level
of system performance and the number of scanheads and system features.
 
  Premium Performance. The premium market segment, comprising about 18% of the
world market for ultrasound products, is characterized by ultrasound systems
that typically sell for over $160,000 per unit. These systems provide the
physician with superior definition of subtle tissue characteristics and
incorporate high resolution gray scale imaging, advanced color velocity,
power, and spectral Doppler capability, image acquisition storage, display and
review capability, advanced automation capabilities, and other features
providing additional clinical utility. Typically, systems sold in the premium
market are equipped with a wide variety of specialty scanheads. Advanced HDI
3000 and the HDI 3000cv systems are ATL's premium performance products.
 
  High Performance. The high performance market, comprising about 36% of the
world ultrasound market, is characterized by systems with high resolution gray
scale imaging and advanced color velocity, power and spectral Doppler
capabilities. Systems in this market segment sell between $100,000 and
$160,000 per unit and generally include advanced measurement and analysis
software, image review capabilities, and a variety of scanhead offerings. ATL
sells the HDI 3000 standard system, the Apogee 800PLUS, and fully configured
HDI 1000 systems in this market segment.
 
  Mid-Range. The mid-range market segment, comprising about 28% of the world
ultrasound market, is characterized by ultrasound systems that sell between
$50,000 and $100,000 per unit. These units are basic gray scale imaging, color
and spectral Doppler systems used for routine examinations and reporting and
utilize a minimum number of scanheads. Many of these systems are sold to small
hospitals and clinics and are used in radiology, cardiology and OB/GYN
applications. Refurbished premium and high performance systems with fewer
purchased optional features are also sold in this price range. ATL's products
in this market segment include the HDI 1000 system and the the Apogee 800PLUS
system.
 
  Low-End. The low-end market segment makes up the remaining 18% of the market
and is characterized by basic black and white imaging systems that sell below
$50,000 per unit. These systems provide limited diagnostic information and are
used primarily for monitoring fetal development and in other basic radiology
and OB/GYN applications. Most of these systems are sold to private office
practitioners and small hospitals. Due to the growing acceptance and
affordability of color Doppler systems, units with only greyscale capability
represent the slowest growing portion of the market. ATL does not presently
compete in this market segment.
 
  GEOGRAPHIC AREAS. The ultrasound market is divided into four major
geographic markets.
 
  North America. The United States and Canada together comprise about 31% of
the world ultrasound market. This market traditionally has been characterized
by its emphasis on high performance systems driven by competition for patient
referrals. These factors encourage the rapid adoption of new technology. Over
the past four years, the emphasis in the United States has turned to more
efficient health care delivery and managed care, and been marked by
considerable consolidation of health care organizations. The predominately
western trend toward managed care has now begun to manifest itself strongly in
the eastern U.S., creating new uncertainties among healthcare buyers. With
consolidation and economic pressures, the U.S. market has become increasingly
value conscious while the installed base of ultrasound technology has
continued to age as a whole.
 
 
                                       8
<PAGE>
 
  Europe. The European market, at 35% of the market, is the largest regional
market for ultrasound systems. European health care systems are more
centralized than the United States market and are often subject to more rigid
governmental regulation. In 1996 the European markets and economies began to
markedly improve in relation to previous recessionary characteristics. The
more regulated character of health care in Europe provides more stability to
the European markets than is evident in the U.S. during economic cycles of
growth and contraction. Value consciousness and state regulated health care
has been characteristic of European markets for a number of years, unlike the
United States where these effects are of relatively recent origin.
 
  Japan. This market accounts for approximately 16% of worldwide ultrasound
sales. Its complex distribution system is highly competitive and Japanese
manufacturers account for almost all sales. In 1996 ATL began to experience an
emerging market presence in Japan through the efforts of Hitachi Medical
Corporation (HMC), ATL's exclusive distributor in the Japanese market. Sales
of the HDI 3000 product began in the spring following the receipt of Japanese
regulatory approval of the product by HMC.
 
  Asia Pacific and Latin America. The remaining geographic areas of the world
account for approximately 18% of the market, and are among the world's fastest
growing markets for ultrasound. The Australian market is similar in structure
to many European countries. Parts of Asia and Latin America represent some of
the fastest growing areas for high performance and mid-range ultrasound
products. Many of the newly developing countries in these regions are devoting
substantial resources to building a health care infrastructure. Many
ultrasound systems sold in these regions are mid-range systems, refurbished
systems or new low-priced Japanese systems.
 
RESEARCH AND DEVELOPMENT
 
  The high technology ultrasound business is characterized by rapidly evolving
technology, resulting in relatively short product life cycles and continuing
competitive pressure to develop and market new products and new features for
existing products. Although the Company intends to continue extensive research
and development activities, there can be no assurance that it will be able to
develop and market new products on a cost-effective and timely basis, that
such products will compete favorably with products developed by others, or
that the Company's existing technology will not be superseded by new
discoveries by competitors.
 
  In February, 1996 the University of Washington and ATL announced that they
and partners VLSI Technology, Inc. and Harris Semiconductor had been awarded
funding under the Technology Reinvestment Project by the Advanced Research
Project Agency of the U.S. Department of Defense to develop an ultrasound
diagnostic instrument small enough to hold in one's hand for use in
battlefield and trauma situations. Work under this program commenced in June,
1996 and will continue for several years, during which time government funding
is being provided as program milestones are achieved. The partners in the
program will retain the rights to commercial applications of the program's
developments. In February, 1997 the Company announced that it has formed a
business unit within the Company which has as its objective the
commercialization of the technology resulting from this program.
 
  In August, 1996 the Company jointly announced with Vital Images, Inc. that
the two companies had entered into agreements for the exclusive development
and marketing of 3D ultrasound imaging products utilizing Vital Images' volume
rendering technology. Under the agreements Vital Images will receive royalties
on ATL sales of the jointly developed products.
 
MANUFACTURING
 
  The Company manufactures its ultrasound system products at its facility in
Bothell, Washington. The Echo Ultrasound division of ATL is located in
Reedsville, Pennsylvania. Scanheads for ATL products are manufactured in both
Reedsville and Bothell.
 
  The Company purchases certain unique scanheads from original equipment
manufacturers. The Company also purchases the hard-copy output devices sold
with its ultrasound systems, such as VCRs and cameras, and
 
                                       9
<PAGE>
 
other materials and component parts. The OEM scanheads and many of the
materials and components used by ATL in the manufacture of ultrasound
equipment are available from more than one source of supply. Certain
components, however, are single sourced, such as crystals and integrated
circuits which are critical to the quality and manufacture of ultrasound
equipment. Vendors can also experience difficulty in meeting quality standards
the Company requires of its vendors. While any of these single-source items
could be replaced over time, abrupt disruption in the supply of a single-
source part could have a material adverse effect on ATL's manufacture of the
products relying on such items. In addition, these items generally have long
order lead times, restricting the Company's ability to respond quickly to
changing market conditions.
 
  Manufacturing efforts can also be impeded by third party assertions of
patent infringement by the Company's products. There can be no assurance the
Company will not be subject to claims of patent infringement by other parties
or that such claims will not require the Company to pay substantial damages or
delete certain features from its products or both. See ITEM 3, Legal
Proceedings, below.
 
SALES AND MARKETING
 
  The Company's sales and marketing strategy has been to compete in all of the
major clinical, price and geographic segments of the ultrasound market with
the exception of the very low priced market segment. In the United States, the
Company markets its products through its direct sales organization. The United
States general imaging sales organization is organized into two geographic
zones, each staffed with regional management, sales representatives and
clinical application specialists knowledgeable in radiology, OB/GYN, and
peripheral vascular applications. A specialized sales force with its own
clinical application specialists offers the Company's cardiology products to
customers in the United States. The role of the application specialists is to
demonstrate the products and train customers in their clinical use.
 
  The Company markets its products internationally through its direct sales
and service operations in Argentina, Australia, Austria, Belgium, Canada,
France, Germany, Hong Kong, Italy, the Netherlands, the United Kingdom and
Singapore. In addition, the Company markets its products in India through a
joint venture with Indchem Electronics. Other principal markets are covered
through a distributor network. European, Middle Eastern and African dealers
are managed through ATL's offices in Germany. Distributors serving the Pacific
Rim countries, Latin America and South America are managed from Bothell,
Washington. Customers outside of the United States accounted for 49% of
revenues in 1996.
 
  The Company's marketing efforts emphasize the development of strong
relationships with key medical professionals, participation in national and
regional meetings and conventions for physicians and hospitals, direct mail
advertising, journal advertising and sponsorship of educational programs.
 
CUSTOMER SUPPORT AND WARRANTY
 
  The Company warrants its new and used products for all parts and labor
generally for one year from the date of original delivery. The Company offers
a variety of post-warranty service agreements permitting customers to contract
for the level of equipment maintenance they require. Alternatively, customers
can contact ATL as needed and receive service at rates based on labor and cost
of parts. The Company's warranty costs are included in cost of product sales
in ITEM 8, Financial Statements and Supplementary Data.
 
  The Company maintains its own customer support organization in the United
States and other countries where the Company has direct operations. Local
dealers and distributors provide service and support in other countries. The
Company provides manuals and expedites delivery of repair parts to all
geographic locations from its facility in Bothell, Washington, with the
assistance of its direct operations in Europe.
 
  The Company's customer service organizations are an integral part of its
sales effort because a customer's decision to purchase a particular product is
based in part on the availability and reputation of the service for that
product. In addition, the customer support group sells and installs upgrades
for existing customers and provides
 
                                      10
<PAGE>
 
training for biomedical technicians so customers can service their own
systems. The customer support group also provides customer education programs
on clinical applications and the use of the Company's products.
 
COMPETITION
 
  The ultrasound market is highly competitive. The Company competes worldwide
in the major clinical applications of the ultrasound market, in the mid and
upper price ranges and in each major geographic market. Four companies--
Toshiba Corporation's Medical Systems Group, ATL, Hewlett-Packard Company's
Medical Products Group and Acuson Corporation--account for approximately 60%
of the worldwide ultrasound market. The Company believes that these four
companies have similar market shares. Toshiba, ATL, and Acuson participate in
all of the major clinical ultrasound markets. Hewlett-Packard holds the
largest individual market share in the cardiology and vascular markets, and in
the fall of 1996 introduced a mid-range general imaging product.
 
  The year 1996 was marked by a significant influx of new product offerings by
the Company's competitors, continuing a trend which began in 1995. The many
new product offerings have made the ultrasound market even more competitive
than in the past, as customers have an even broader range of products from
which to choose. The breadth of new products from many companies appears to
have lengthened the time required for customers to make decisions to purchase,
since customers have many more products to consider before making a purchase
decision. Most of the recent competitive products are based upon digital
technology to varying degrees, as competitors attempt to position their new
products as comparable to those of ATL, which pioneered digital ultrasound
systems over a decade ago.
 
  Many of the Company's major competitors, such as Hewlett-Packard Company's
Medical Products Group, Toshiba' Medical Systems Group, General Electric
Medical Systems, Inc., the Diasonics subsidiary of Elbit, Inc., and Siemens
Medical Systems, Inc., are divisions or subsidiaries of companies much larger
than ATL. General Electric and Siemens, as well as Toshiba and others, have
multi-modality medical imaging product offerings, including MRI, CT, nuclear
medicine and x-ray products in addition to ultrasound. These companies and
several of the Company's other competitors have far greater financial,
marketing, servicing, technical and research and development resources than
those of the Company, and are able to support and sustain their efforts in the
ultrasound market with resources derived from other imaging modalities and
businesses.
 
  The Company believes that significant competitive factors in the diagnostic
ultrasound market include the clinical performance of systems, depth of
product line, reputation for technology leadership, upgradeability to advanced
features, availability of Company-provided purchase financing, reliability,
ease of use and price of products and service. See "Research and Development."
The Company believes that it presently competes favorably with respect to each
of these competitive factors, however, there can be no assurances that the
Company will be able to fully respond to competitive inroads by companies with
far greater resources than ATL.
 
  Ultrasound is only one of a number of diagnostic imaging technologies
currently available, including conventional x-ray, angiography, CT, magnetic
resonance imaging and P.E.T. A development in another diagnostic technology,
and declining prices for these other products which bring them into the range
of price competition with ultrasound, could adversely affect ATL and the
ultrasound industry.
 
PATENTS, TRADEMARKS AND LICENSES
 
  The Company has obtained patents on certain of its products and has applied
for patents which are presently pending. The Company has also sought trademark
protection for the brand names of the products it currently markets. There can
be no assurance that any additional patents will be issued or that trademark
protection will be granted and maintained.
 
  Certain critical technology incorporated in the Company's products,
including software algorithms, broad bandwidth scanhead technology and ASIC
(application-specific integrated circuit) technology, is protected by
 
                                      11
<PAGE>
 
copyright laws and confidentiality and licensing agreements. The Company's
proprietary digital beamformer is protected by confidentiality agreements,
patents, copyright and trade secret law. There can be no assurances that these
modes of intellectual property protection will continue to maintain the
proprietary aspects of ATL's technology.
 
  Companies in high technology businesses routinely review the products of
others for possible conflict with their own patent rights. The Company has
from time to time received notices of claims from others alleging patent
infringement. While the Company believes that it does not infringe any valid
patent of any third party, there can be no assurance that the Company will not
be subject to future claims of patent infringement or that any claim will not
require the Company to pay substantial damages or delete certain features from
its products or both. While such claims could temporarily interrupt the
Company's ability to ship affected products, the Company believes that any
such interruption can be overcome by technical changes to product features.
See ITEM 3, Legal Proceedings, below.
 
GOVERNMENTAL REGULATION
 
  Product Regulation. The Company's products are subject to extensive
regulation by numerous governmental authorities, principally the FDA and
corresponding state and foreign agencies, and to various domestic and foreign
electrical safety and emission standards. The FDA has broad regulatory powers
with respect to preclinical and clinical testing of new medical products and
the manufacturing, marketing and advertising of medical products. The
Company's product development processes, manufacturing facilities, and the
manufacture of its products are subject to FDA regulations respecting
registration of manufacturing facilities and compliance with the FDA's Good
Manufacturing Practices ("GMP") regulations. The Company is also subject to
periodic on-site inspection for compliance with such regulations. The
Company's ability to obtain timely FDA export and new product approvals is
dependent upon the results of such inspections. In February, 1996 the FDA
concluded a comprehensive inspection of the Company's Bothell, Washington
facilities as a part of the approval process for ATL's breast PMA for its
Ultramark 9 HDI system. In January, 1997 the FDA concluded a similar
inspection attendant to its approval of ATL's breast PMA supplement for the
HDI 3000 system. The FDA has notified ATL that the Company has satisfied the
requirements of both inspections. The Company's Nova MicroSonics division also
was inspected and passed an FDA GMP audit in 1996.
 
  The FDA requires that all medical devices introduced to the market be
preceded either by a premarket notification clearance order under Section
510(k) of the Federal Food, Drug and Cosmetic Act, as amended (the "FDC Act"),
or an approved PMA application. A 510(k) premarket notification clearance
order indicates FDA agreement with an applicant's determination that the
product for which clearance has been sought is substantially equivalent to
medical devices that were on the market prior to 1976 or have subsequently
received clearance. An approved PMA application indicates that the FDA has
determined that the device has been proven, through the submission of clinical
trial data and manufacturing quality assurance information, to be safe and
effective for its labeled indications. The process of obtaining 510(k)
clearance typically takes approximately six to nine months, while the
premarket approval application process typically lasts more than a year. All
of ATL's current products have 510(k) clearance and additionally, the
Ultramark 9 HDI and HDI 3000 systems are cleared to be marketed under ATL's
breast PMA application.
 
  The Company believes that its products comply generally with applicable
electrical safety standards, such as those of Underwriters Laboratories and
non-U.S. safety standards authorities. Several countries have, in recent
years, changed the electronic emission requirement which must be met by
ultrasound equipment. There can be no assurances that the Company will be able
to continue to respond to these continually changing regulatory requirements
in a timely manner.
 
  The Company's regulatory compliance programs have been expanded to encompass
verification of the Company's compliance with international standards for
medical device design, manufacture, installation, and servicing known as ISO
9001 standards. All of the Company's manufacturing facilities have qualified
for ISO 9001 registration. In addition, several of the Company's international
sales and service subsidiaries received
 
                                      12
<PAGE>
 
certification under the ISO 9002 standards for sales and service entities. ISO
9001 standards will become mandatory in Europe in 1999. The FDA is in the
process of adopting the ISO 9001 standards as regulatory standards for the
United States, and it is anticipated these standards will be phased in for
U.S. manufacturers of medical devices over a period of time. In 1996 the
Company passed a full biennial review of its ISO certifications by a European
inspecting authority.
 
  ATL's HDI 3000 system has received the European Community (CE) mark in
Europe. The CE mark means that the HDI 3000 satisfies the regulatory
requirements of all of the countries of the European community, enabling the
product to be freely marketed throughout Europe. The CE mark will be required
to market products in Europe beginning in 1998. The Company expects to have
the CE mark for the HDI 1000 system by the time customer shipments commence in
the second quarter of 1997.
 
  Federal, state and foreign regulations are constantly undergoing change. The
increasing attention given to the national health care legislation has caused
U.S. ultrasound customers to become more cautious in making expenditures and
investing in capital equipment. In addition, the U.S. health care system has
undergone significant consolidations and restructuring in recent years. The
Company cannot predict what effect, if any, such change may have on its
business, or when the deleterious effect of these conditions on its business
will change.
 
  Reimbursement. The Company's products are used by health care providers for
diagnostic testing services and other services for which the providers may
seek reimbursement from third-party payers, principally, in the United States,
Medicare, Medicaid and private health insurance plans. Such reimbursement is
subject to the regulations and policies of governmental agencies and other
third-party payers. For example, the Medicare program, which reimburses
hospitals and physicians for services provided to a significant percentage of
hospital patients, places certain limitations on the methods and levels of
reimbursement of hospitals for procedure costs and for capital expenditures
made to purchase equipment, such as that sold by the Company. The Medicare
program also limits the level of reimbursement to physicians for diagnostic
tests. The state-administered Medicaid programs and private payers also place
limitations on the reimbursement of both facilities and physicians for
services provided in connection with diagnostic and clinical procedures.
Reduced governmental expenditures in the United States and many other
countries continue to put pressure on diagnostic procedure reimbursement. The
Company cannot predict what changes may be forthcoming in these policies and
procedures, nor the effect of such changes on its business.
 
  Third-party payers worldwide, including governmental agencies, are under
increasing pressure to contain medical costs. Limits on reimbursement or other
cost containment measures imposed by third-party payers may adversely affect
the financial condition and ability of hospitals and other users to purchase
products, such as those of the Company, by reducing funds available for
capital expenditures or otherwise. The Company is unable to forecast what
additional legislation or regulation, if any, relating to the health care
industry or third-party reimbursement may be enacted in the future or what
effect such legislation or regulation would have on the Company.
 
  Environmental. The Company is subject to Federal, state and local provisions
regulating the discharge of materials into the environment or otherwise for
the protection of the environment. Although the Company's current operations
have not been significantly affected by compliance with environmental laws or
regulations, Federal, state and local governments are becoming increasingly
sensitive to environmental issues, and the Company cannot predict what impact
future environmental regulations may have on its operations.
 
  Employees. As of December 31, 1996, the Company had 2,703 employees
worldwide. None of the Company's United States employees is covered by
collective bargaining agreements, and the Company considers its employee
relations to be satisfactory.

ITEM 2. PROPERTIES
 
  The Company owns two buildings on the corporate campus at 22100 Bothell
Everett Highway, Bothell, Washington 98041, consisting of 365,000 square feet.
These buildings include the Company's corporate headquarters and its major
manufacturing facility, as well as the Company's research and development,
sales, service, marketing and administrative functions. In February, 1997 the
Company's Board directed management to begin planning construction of a third,
smaller building on the corporate campus. The Company also leases space in
several buildings in nearby business parks.
 
  The Company's Nova MicroSonics division occupies approximately 33,000 square
feet in leased buildings in Allendale, New Jersey and Indianapolis, Indiana,
and the Echo Ultrasound division occupies 63,000 square feet in a building
owned by the Company in Reedsville, Pennsylvania. ATL continues to own a
building of 70,000 square feet in Ambler, Pennsylvania, which is occupied by
the Company's cardiology sales organization. The Company plans to lease unused
space in the Ambler building.
 
  The Company's direct business operations in the United States and other
countries lease office and warehouse space in their respective countries.
 
  There are no significant unutilized facilities for ongoing operations, other
than discussed above, and the Company believes its existing facilities are
sufficient to meet its near-term operating requirements.
 
 
                                      14

ITEM 3. LEGAL PROCEEDINGS
 
  The Company is subject to various claims and other proceedings which arise
in the ordinary course of its businesses and believes that such proceedings,
individually or in the aggregate, will not have a material adverse effect on
the business or financial condition of the Company. Insured claims arising
from ATL's businesses are covered by the Company's insurance policies. The
Company intends to maintain insurance coverage against business risks at
levels that take into account the nature and magnitude of the respective
businesses to be conducted by ATL. There can be no assurance that the
Company's current insurance coverage will prove adequate or that the amount or
type of coverage available to the Company will remain available on a cost-
effective basis.
 
  In May 1996, a U.S. District Court in California ordered the Company to pay
damages in the amount of $27.9 million together with interest, costs and
attorney fees on a patent infringement claim by SRI International, Inc.
("SRI") relating to an electrical circuit alleged to be used in several of the
Company's discontinued products. The patent expired in 1994. The Company has
filed an appeal of the amount awarded with the Federal Circuit Court of
Appeals in Washington, D.C. and is presently awaiting the decision of the
appellate court on the appeal. The Company stayed payment of the damages award
during the pendency of the appeal by posting a supersedeas bond with the
California court. The Company has accrued a provision for the full amount of
the damages awarded and will continue to accrue interest during the appeal
process. See Note 10 of the Notes to the Consolidated Financial Statements on
page 25 of the 1996 Annual Report to Shareholders incorporated by reference
herein. There can be no assurance the Company will not be subject to claims of
patent infringement by other parties or that such claims will not require the
Company to pay substantial damages or delete certain features from its
products or both.

  Under date of February 14, 1997 we reported on the consolidated balance
sheets of Advanced Technology Laboratories, Inc. and subsidiaries as of

operations, shareholders' equity, and cash flows for each of the years in the
three-year period ended December 31, 1996, as contained in the 1996 annual
report to shareholders. These consolidated financial statements and our report
thereon are incorporated by reference in the annual report on Form 10-K for
the year 1996. In connection with our audits of the aforementioned

statement schedule based on our audits.
 
  In our opinion, such financial statement schedule, when considered in

                            Meetings of Shareholders 
 
SECTION 1.  Annual Meetings 
 
            The annual meeting of the shareholders for the election of directors
and for the transaction of such other business as may properly come before the
meeting shall be held at such place, date and hour as shall be designated in the
notice thereof given by or at the direction of the Board of Directors.
 
SECTION 2.  Special Meetings 
 
            Except as otherwise required by law and subject to the rights of the
holders of any class or series of stock having a preference over the Common
Stock as to dividends or upon liquidation, special meetings of the shareholders
for any purpose or purposes may be called only by, and shall be held at such
place, date and hour as shall be designated by (i) holders of two-thirds or more
of the voting power of the then-outstanding shares of stock of all classes and

law, notice of any adjourned meeting of the shareholders need not be given.  
Notice of any meeting of shareholder shall not be required to be given to any
shareholder who shall attend such meeting in person or by proxy, except when

the beginning of the meeting, to the transaction of any business because the
meeting is not lawfully called or convened.  A written waiver of notice,

stated therein, shall be deemed equivalent to the notice required by

            It shall be the duty of the Secretary or other officer of the 
Corporation who shall have charge of its stock ledger to prepare and make, 
at least 10 days before every meeting of the shareholders, a complete list of 
the shareholders entitled to vote thereat, arranged in alphabetical order and 
by voting group, and showing the address of each shareholder and the number 
of shares registered in the name of each shareholder.  Such list shall be 
open to the examination of any shareholder, for any purpose germane to the 
meeting, during ordinary business hours, for a period of at least 10 days 
prior to the meeting at the principal office of the Corporation.  Such list 
shall also be produced and kept at the time and place of the meeting during 
the whole time thereof, and may be inspected by any shareholder who is 
present. 
 
SECTION 5.  Quorum 
 
            At each meeting of the shareholder, except as otherwise expressly 
required by law or by the Articles of Incorporation, shareholders holding one-
third of the shares of stock of the Corporation issued and outstanding, and 
entitled to be voted thereat, shall be present in person or by proxy to 
constitute a quorum for the transaction of business.  In the absence of a 
quorum at any such meeting or any adjournment or adjournments thereof, a 
majority in voting interest of those present in person or by proxy and 
entitled 

                                       2
<PAGE>
 
to vote thereat, or in the absence therefrom of all the shareholders, any 
officer entitled to preside at, or to act as Secretary of, such meeting may 
adjourn such meeting from time to time until shareholders holding the amount 
of stock requisite for a quorum shall be present in person or by proxy.  At 
any such adjourned meeting at which a quorum may be present any business may 
be transacted which might have been transacted at the meeting as originally 
called.

            At each meeting of the shareholders, one of the following shall act

            (b)  the President; 
 
            (c) any other officer of the Corporation designated by the Board or
the Executive Committee to act as chairman of such meeting and to preside
thereat if the Chairman of the Board and the President shall be absent from such
meeting; or
 
            (d)  a shareholder of record of the Corporation who shall be chosen 
chairman of such meeting by a majority in voting interest of the shareholder 
present in person or by proxy and entitled to vote thereat.  The Secretary, 
or, if he shall be presiding over the meeting in accordance with the 
provisions of this Section, or, if he shall be absent from such meeting, the 
person (who shall be an Assistant Secretary, if an Assistant Secretary shall 
be present thereat) whom the chairman of such meeting shall appoint, shall 
act as secretary of such meeting and keep the minutes thereof. 
 
SECTION 7.  Order of Business 
 
            (a) Annual Meetings.  At an annual meeting of the shareholders, only
                ---------------
such business shall be conducted as shall have been properly brought before 
the meeting.  To be properly brought before an annual meeting, business must 
be (i) specified in the notice of the meeting (or any supplement thereto) 
given by or at the direction of the Board of Directors, (ii)  otherwise 
brought before the meeting by or at the direction of the Board of Directors 
or (iii)  brought before the meeting by a shareholder in accordance with the 
procedure set forth below.  Subject to the rights of the holders of any class
or series of stock having a preference over the Common Stock as to dividends 
or upon liquidation, for business to be properly brought before an annual 
meeting by a shareholder, the shareholder must have given written notice 
thereof, either by personal delivery or by certified or registered United 
States mail, postage 

                                       3
<PAGE>
 
prepaid, to the Secretary of the Corporation, not later than 90 days in 
advance of the Originally Scheduled Date (as such term is defined below) of 
such meeting; provided, however, that if such annual meeting of shareholders 
              --------  -------
is held on a date earlier than the first Tuesday in May, such written notice 
must be given within 10 days after the first public disclosure (which may be 
by a public filing by the Corporation with the Securities and Exchange 
Commission) of the Originally Scheduled Date of the annual meeting.  Any such 
notice shall set forth as to each matter the shareholder proposes to bring 
before the annual meeting (A)  a brief description of the business desired to 
be brought before the meeting and the reasons for conducting such business at 
the meeting and, in the event that such business includes a proposal to amend 
either the Articles of Incorporation or Bylaws of the Corporation, the 
language of the proposed amendment, (B)  the name and address of the 
shareholder proposing such business, (C)  a representation that the 
shareholder is a holder of record of stock of the Corporation entitled to vote 
at such meeting and intends to appear in person or by proxy at the meeting to 
propose such business and (D)  any direct or indirect material interest of the 
shareholder in such business.  No business shall be conducted at an annual 
meeting except in accordance with this paragraph, and the chairman of any 
annual meeting of shareholders may refuse to permit any business to be brought 
before such annual meeting without compliance with the foregoing procedure.  
For purposes of these Bylaws, the "Originally Scheduled Date" of any meeting 
of shareholders shall be the date such meeting is scheduled to occur in the 
notice of such meeting first given to shareholders regardless of whether such 
meeting is continued or adjourned and regardless of whether any subsequent 
notice is given for such meeting or the record date of such meeting is changed.
 
     (b)  Special Meetings.  At a special meeting of the shareholder, only 
          ----------------
such business as is specified in the notice of such special meeting given by 
or at the direction of the person or persons calling such meeting in 
accordance with Section 2 of this Article II shall come before such meeting. 
 
SECTION 8.  Voting 
 
            Except as otherwise provided in the Articles of Incorporation, each 
shareholder shall, at each meeting of the shareholders, be entitled to one 
vote in person or by proxy for each share of stock of the Corporation held by 
him and registered in his name on the books of the Corporation:

                           BEFORE-TAX CONTRIBUTIONS


3.1  Salary Deferral Agreement
     -------------------------

     (a)  General
          -------
          A  Participant  who  desires to make  salary  deferrals
          pursuant  to  this  Section 3.1 shall  enter  a  salary
          deferral  agreement with the Participating  Company  in
          accordance  with the procedures in Section  3.3.   Such
          agreement  shall authorize the Company to make  payroll
          deductions  equal  to  a whole percentage  of  Earnings
          between   1%   and   16%   designated   as   Before-tax
          Contributions.  Payroll deductions shall  be  based  on
          Earnings for each payroll period.

          To the extent a Participant's salary deferral agreement
          is based on a percentage of Earnings, the dollar amount
          of   a   Participant's   salary   deferral   shall   be
          automatically increased or decreased to reflect changes
          in the amount of the Participant's Earnings.

          The salary deferral agreement shall be effective on the
          first  day  of  the payroll period coinciding  with  or
          following  the  later of:  (1) the  date  participation
          commences,  or  (2) the first day of  the  month  which
          coincides  with  or  next  follows  completion  of  the
          agreement,  and  shall  remain  in  effect  until  such
          agreement  is  superseded by a subsequent agreement  or
          revoked.   Deferrals shall be deducted from Participant
          Earnings each payroll period, except for those  periods
          in   which  the  deferral  amount  exceeds  the  amount
          remaining after other payroll deductions.  In the event
          a  deduction  is  not  taken in a payroll  period,  the
          Committee,   with  sole  discretion,  shall   determine
          whether  there  will  be  a  make-up  deduction  in   a
          subsequent payroll period.

     (b)  Maximum Dollar Contribution
          ---------------------------
          Notwithstanding the foregoing, Before-Tax Contributions
          for any calendar year to this Plan (and any other plans
          of  Affiliated Companies subject to Section  402(g)  of
          the   Code)   shall  not  exceed  the  maximum   dollar
          limitation  on elective deferrals under Section  402(g)
          of the Code ($9,500 for 1997).

3.2  Participant Modification of Salary Deferral Agreement
     -----------------------------------------------------

     The   payroll  deduction  percentages  designated   in   the
     Participant's  salary deferral agreement shall  continue  in
     effect   regardless  of  changes  in  Earnings   until   the
     Participant  elects in writing to change the percentage.   A
     Participant  may change the deferral amount by completing  a
     new  salary  deferral  agreement and submitting  it  to  the
     Committee.  Completion of a salary deferral agreement  shall
     automatically  revoke all prior salary  deferral  agreements
     entered into by a Participant.

                                      12
<PAGE>
 
     A Participant may discontinue contributions effective on the
     first  day of a future month by submitting a written request
     to the Committee.  A Participant may resume contributions on
     the  first  day  of  a future month by submitting  a  salary
     deferral agreement.
     
     A  Participant  may change the deferral amount,  discontinue
     contributions, or resume contributions as frequently as each
     month,  as  long  as  the Participant submits  a  form  that
     satisfies the procedures in Section 3.3.

3.3  Procedure for Making and Revoking Salary Deferral Agreement
     -----------------------------------------------------------

     The  salary  deferral  agreement  and  any  modification  or
     cancellation  thereof shall be made by  the  Participant  on
     such  form,  within  such time and in accordance  with  such
     other rules and procedures as prescribed by the Committee.

3.4  Non-Discrimination Test For Deferrals (ADP Test)
     ------------------------------------------------

     For  each  Plan Year, the Plan must meet one of  the  actual
     deferral  percentage  (hereinafter  "ADP")  tests  described
     below  to  satisfy the non-discrimination requirement.   For
     purposes  of this ADP test, Eligible Employees  who  do  not
     qualify for participation pursuant to Section 2 shall not be
     considered.

     (a)  The ADP for the group of Eligible Employees who are 
          Highly Compensated Employees does not exceed the ADP for
          all other Eligible Employees multiplied by 1.25; or

     (b)  The ADP for the group of Eligible Employees who are 
          Highly Compensated Employees (i) is not more than two
          percentage points higher than the ADP for all other
          Eligible Employees and (ii) does not exceed the ADP for
          all other Eligible Employees multiplied by 2.

     The ADP for a specified group of Eligible Employees shall be
     the  average of the ratios (calculated separately  for  each
     Employee  in the group to the nearest one-hundredth  of  one
     percent  of  the Employee's Compensation) of (i) Participant
     Before-tax Contributions to (ii) the Employee's Compensation
     earned   while   eligible  to  participate,  determined   in
     accordance with Code Section 401(k) and regulations pursuant
     thereto.   For purposes of the ADP tests, the definition  of
     "Compensation" may be modified from year to year to mean any
     definition of compensation that complies with Section 414(s)
     of the Code.

     If  for any Plan Year a Highly Compensated Employee is  also
     eligible   to  participate  in  another  cash  or   deferred
     arrangement maintained by any Affiliated Company,  then  the
     ADP  of such Highly Compensated Employee shall be determined
     by  treating all the cash or deferred arrangements in  which
     he  or  she is eligible to participate and this Plan as  one
     arrangement.
     
     For   purposes   of  the  foregoing  test,  all   Before-tax
     Contributions made to this Plan and any other plan which  is
     aggregated  with  this Plan for purposes of  satisfying  

                                  13
<PAGE>
 
     the coverage requirements of Code Section 410(b) (except the
     average  benefits percentage test) shall be treated as  made
     to  a single plan.  In addition, Before-tax Contributions to
     this  Plan  may  be permissively aggregated with  before-tax
     contributions  to  one  or  more  other  cash  or   deferred
     arrangements,  so long as the aggregated plans  satisfy  the
     requirements  of Code Sections 401(a)(4) and  410(b)  as  if
     they were a single plan.

          agreement,  as provided in Section 3, for each  payroll
          period.  Participant contributions shall be credited to
          the Participant's Before-Tax Contribution Account.

          To the extent a Participant's salary deferral agreement
          is based on a percentage of Earnings, the dollar amount
          of  a  Participant's Before-tax Contributions shall  be
          automatically increased or decreased to reflect changes
          in the amount of the Participant's Earnings.

          The  Company  shall  pay  the Participants'  Before-tax
          Contributions   in  cash  to  the  Trustee   within   a
          reasonable  time  after each payroll  period   but  not
          later  than the fifteenth (15th) day of the first (1st)
          month beginning after the payroll period ends.

     (b)  Employee After-tax Contributions
          --------------------------------
          A  Participant  may elect to contribute  to  the  Plan,
          through payroll deductions, an amount equal to a  whole
          percentage  of Earnings between 1% and 16%, reduced  by
          the amount (if any) of the Before-Tax Contributions  to
          be made on his behalf.  Such amounts are referred to as
          After-Tax  Contributions.  A Participant may make  such
          election  by  submitting  to the  Committee  a  written
          request  which  authorizes a deduction of contributions
          from  his  or  her  Earnings.  After-tax  Contributions
          shall   be  credited  to  the  Participant's  After-tax
          Contribution Account.

          An  election  to  make After-tax Contributions  may  be
          made,   modified  or  canceled  subject  to  the   same
          provisions   that  apply  to  Before-tax  Contributions
          pursuant to Sections 3.2 and 3.3.

          The   dollar   amount  of  a  Participant's   After-tax
          Contributions  shall  be  automatically  increased   or
          decreased  to  reflect changes in  the  amount  of  the
          Participant's Earnings.

          The  Company  shall  pay  the  Participants'  After-tax
          Contributions   in  cash  to  the  Trustee   within   a
          reasonable  time after each pay-period, but  not  later
          than  the fifteenth (15th) day of the first (1st) month
          beginning after the payroll period ends.

     (c)  Company Matching Contributions
          ------------------------------
          Each   Company   shall   make  the   Company   Matching
          Contribution for any Plan Year in an amount equal to:

          (i)  50% of each Participant's Before-tax Contributions 
               and After-tax Contributions up to three percent
               (3%) of Earnings paid by the Company during such
               Plan Year; and

          (ii) 25% of each Participant's Before-tax Contributions 
               and After-tax Contributions over 3% and up to 6%
               of Earnings paid by the Company during such Plan
               Year.

          Provided   that,  Participant  Lump  Sum   Supplemental
          Contributions pursuant to Section 4.1(e)  will  not  be
          matched by a Company Matching Contribution.  Thus,  the
          maximum Company Matching Contribution for a Participant
          who  contributes at least six percent (6%) of Earnings,
          is two and one quarter percent (2 1/4%).

          Such   amounts   shall  be  called   Company   Matching
          Contributions.  The  percentage  of  Company   Matching
          Contributions  shall be determined separately  for  the
          Company from time to time by the Board, subject to  the
          percentage  limitations  contained  in  the   preceding
          sentence.   The  rate of Company Matching Contributions
          shall  be  certified to the Committee and shall  remain
          effective  until changed by the Board and certified  to
          the Committee.  Company Matching Contributions shall be
          credited   to   the   Participants'  Company   Matching
          Contribution Accounts.

          The  amount  of the Company Matching Contributions  due
          under  this  Section  4.1(c) (reduced  by  any  Company
          Matching  Contributions forfeited during the month,  as
          provided  in  Section  8.2) shall  be  determined  each
          payroll  period  during  the Plan  Year  and  shall  be
          remitted to the Trustee within a reasonable time  after
          each  pay  period but not later than a reasonable  time
          after the end of each month.

          The  Company may, at its option, make its contributions
          under  this  Section 4.1(c) that are  invested  in  the
          Company  Stock  Fund by delivering  or  causing  to  be
          delivered to the Trustee shares of Company Stock at the
          aggregate  Current  Market  Value  of  the   stock   so
          delivered  on  the date of the delivery.   Such  shares
          shall  be  treasury  shares,  authorized  but  unissued
          shares or shares purchased on the open market.

     (d)  Supplemental Company Contributions
          ----------------------------------
          On  the  last  day of the Plan Year, each Participating
          Company  may  contribute  a  uniform  percentage  of  a
          Participant's  Earnings, on behalf of each  Participant
          who completed 1,000 or more Hours of Service during the
          Plan Year and (i) who is employed on the first and last
          days  of  the Plan Year, (ii) who terminated employment
          during  the  Plan  Year  as  a  result  of  

                                      16
<PAGE>
 
          retirement, Disability or death, or (iii) who was employed  
          by the  Participating  Company but who  was  transferred  
          during  the  Plan  Year to the  employ of  an Affiliated 
          Company that is not a Participating Company.

          Amounts  contributed by each Participating Company  may
          be  different  from the amount contributed  by  another
          Participating  Company.  Amounts  contributed  by  each
          Participating  Company  will  be  allocated   only   to
          Participants  employed  by that Participating  Company,
          based  on  Earnings paid by that Participating Company.
          Such  amounts  are referred to as Supplemental  Company
          Contributions  and  shall be credited  to  Supplemental
          Company  Contribution  Accounts.   The  percentage   of
          Supplemental Company Contributions shall be  determined
          separately for each Participating Company by the Board.

          Supplemental Company Contributions shall be remitted to
          the  Trustee on or before the due date for  filing  the
          Company's Federal income tax return for the Plan  Year,
          including extensions.

          A  Participating Company may, at its option,  make  its
          contributions  under  this  Section  4.1(d)  that   are
          invested  in  the Company Stock Fund by  delivering  or
          causing  to  be  delivered to  the  Trustee  shares  of
          Company Stock at the aggregate Current Market Value  of
          the  stock so delivered on the date of delivery.   Such
          shares   shall  be  treasury  shares,  authorized   but
          unissued shares or shares purchased on the open market.

     (e)  Lump-Sum Supplemental Contributions
          -----------------------------------
          In  addition to any other contributions made by him,  a
          Participant  who has completed at least five  years  of
          Service  with  the  Participating Company  may  make  a
          contribution to the Plan, effective as of the last  day
          of   any   month,  by  delivering  a   check   to   the
          Participating Company, provided that no more  than  two
          Lump-Sum   Supplemental  Contributions  may   be   made
          hereunder by a Participant in any calendar year.  Lump-
          Sum  Supplemental  Contributions shall  be  treated  as
          After-tax   Contributions   and   credited    to    the
          Participant's After-tax Contribution Account.

          The   Company   shall  pay  the  Lump-Sum  Supplemental
          Contributions   in  cash  to  the  Trustee   within   a
          reasonable time after receipt of a Participant's check.

     (f)  Rollover Contributions
          ----------------------
          An  Eligible Employee may request in writing on one  or
          more forms required by the Committee that the Committee
          accept  a  rollover amount which was  distributed  from
          another qualified plan, other than a plan maintained by
          the    Company   or   an   Affiliated   Company,   (the
          "distributing  plan")  or  from  a  conduit  Individual
          Retirement Account (IRA).  Also, the Eligible  Employee
          must  provide  any written assurances required  by  the
          Committee  that  such  amounts  are  eligible  rollover
          distributions, including but not limited to  a  written
          statement by the administrator of the 
          
                                      17
<PAGE>
 
          distributing plan that the distributing plan received a  
          determination letter from the Commissioner of the Internal  
          Revenue Service  that the distributing plan is qualified.   
          The amount must be a  direct rollover or must be rolled 
          over by the Eligible Employee within 60 days after receiving
          the  distribution from the other plan or  conduit  IRA.
          Rollovers of any type of property other than cash  will
          not  be  accepted.   In the event an Eligible  Employee
          contributes  a  rollover amount, such amount  shall  be
          allocated  to  a  separate, fully  vested  account  and
          subject  to the same terms of the Plan as other amounts
          in a Before-tax Contribution Account, provided, amounts
          in  a  Rollover Account may be withdrawn in Service  at
          any time.

          If   the   Eligible   Employee  never   satisfies   the
          participation requirements of Section 2,  the  Eligible
          Employee  shall be considered a Participant  only  with
          respect to the rollover amount.

4.2  Time of Contribution
     --------------------

     In  no  event shall contributions for any Plan Year be  made
     later  than the time prescribed by law (i) for the deduction
     of such contributions for purposes of Federal income tax, as
     determined by the applicable provisions of the Code, or (ii)
     for  making  such  contributions under a  cash  or  deferred
     arrangement  (within the meaning of Section  401(k)  of  the
     Code).

4.3  Non-Discrimination  Test for Company Matching  Contributions
     ------------------------------------------------------------
     and After-tax Contributions (ACP Test)
     --------------------------------------

     For  each  Plan Year the Plan must meet one of  the  average
     contribution percentage (hereinafter "ACP") tests  described
     below  to satisfy this non-discrimination requirement.   For
     purposes  of this ACP test, Eligible Employees  who  do  not
     qualify for participation pursuant to Section 2 shall not be
     considered.

     (a)  The ACP for the group of Eligible Employees who are Highly
          Compensated Employees does not exceed the ACP for all other
          Eligible Employees multiplied by 1.25; or

     (b)  The ACP for the group of Eligible Employees who are Highly
          Compensated Employees (i) is not more than two percentage points
          higher than the ACP for all other Eligible Employees and (ii)
          does not exceed the ACP for all other Eligible Employees
          multiplied by 2.

     The ACP for a specified group of Eligible Employees shall be
     the  average of the ratios (calculated separately  for  each
     Employee  in the group to the nearest one-hundredth  of  one
     percent  of  the  Employee's Compensation)  of  (i)  Company
     Matching  Contributions on behalf of each such Employee  and
     the   Employee's   After-tax  Contributions   and   Lump-Sum
     Supplemental  Contributions, if any, to (ii) the  Employee's
     Compensation   earned   while   eligible   to   participate,
     determined  in  accordance  with  Code  Section  401(m)  and
     regulations  pursuant  thereto.  For  purposes  of  the  ACP
     tests, the definition of "Compensation" may be modified from

                                      18
<PAGE>
 
     year  to  year  to mean any definition of compensation  that
     complies with Section 414(s) of the Code.
     
     For  purposes  of  the foregoing test, all Company  Matching
     Contributions,   After-tax  Contributions   and   Lump   Sum
     Supplemental Contributions made to this Plan and  any  other
     plan  which  is  aggregated with this Plan for  purposes  of
     satisfying the coverage requirements of Code Section  410(b)
     (except  the  average  benefits percentage  test)  shall  be
     treated  as  made  to a single plan.  In  addition,  Company
     Matching Contributions, After-tax Contributions and Lump Sum
     Supplemental  Contributions made  under  this  Plan  may  be
     permissively aggregated with matching contributions made  to
     another  plan, so long as the aggregated plans  satisfy  the
     requirements  of Code Sections 401(a)(4) and  410(b)  as  if
     they were a single plan.

     If  for any Plan Year a Highly Compensated Employee is  also
     eligible  to  participate in another plan  offering  company
     matching   contributions   and/or  after-tax   contributions
     maintained by any Affiliated Company, the ACP of such Highly
     Compensated Employee shall be determined by aggregating  all
     such contributions.

4.4  Multiple Use of Alternative Limitations Under ADP and ACP Tests
     ---------------------------------------------------------------

     If  the  sum  of  the  ADP  and ACP for  Highly  Compensated
     Employees  determined  under Section 3.4  and  Section  4.3,
     respectively,  after  correcting  any  excess  deferrals  or
     contributions pursuant to Section 4.5, exceeds the Aggregate
     Limit   defined  below,  then  Highly  Compensated  Employee
     contributions  shall  be further limited  pursuant  to  this
     section.   This multiple use limitation shall be applied  in
     accordance  with  the  provisions of  Treas.  Reg.  Sections
     1.401(m)-1 and 1.401(m)-2.

     The Aggregate Limit means the greater of (a) or (b) below:

     (a)  the sum of:

          (i)  1.25 multiplied by the greater of the ADP or the   
               ACP for the group of all Eligible Employees who
               are not Highly Compensated Employees, and

          (ii) two plus the lesser of the ADP or the ACP for the 
               group of all Eligible Employees who are not Highly
               Compensated Employees (in no event shall this
               amount exceed twice the lesser of such ADP or
               ACP).

     (b)  the sum of:

          (i)  1.25 multiplied by the lesser of the ADP or the ACP 
               for the group of all Eligible Employees who are not 
               Highly Compensated Employees, and

          (ii) two plus the greater of the ADP or the ACP for the 
               group of all Eligible Employees who are not Highly
               Compensated Employees (in

                                      19
<PAGE>
 
               no event shall this amount exceed twice the
               greater of such ADP or ACP).

4.5  Corrective Procedures to Satisfy Discrimination Tests
     -----------------------------------------------------
 
     If  at  any time during a Plan Year the Committee determines
     on  a  projected basis that it is necessary  to  reduce  the
     Participant     Before-tax     Contributions,      After-tax
     Contributions  or  Company  Matching  Contributions  of  any
     Highly  Compensated Employee to satisfy the dollar limit  on
     annual  deferrals, the ADP non-discrimination test, the  ACP
     non-discrimination test, or the multiple use of  alternative
     limitations test, it shall have the authority to  do  so  in
     such  amounts and for such periods of time as it shall  deem
     necessary under the circumstances.

     The  Committee  may,  in  its  sole  discretion,  elect   to
     aggregate Company Matching Contributions and/or Supplemental
     Company    Contributions    with   Participant    Before-tax
     Contributions  to the extent necessary to  satisfy  the  ADP
     discrimination  test  provided  such  aggregation  does  not
     itself  result in discrimination.  Notwithstanding any  Plan
     provisions  to  the contrary, any Company  contributions  so
     aggregated  shall be 100% vested as of the date  contributed
     to   the  Plan  and  shall  be  subject  to  the  withdrawal
     provisions   of  Section  7.4  as  if  they  are  Before-tax
     Contributions.   The ACP test must be passed without  taking
     such Company contributions into account.

     The  Committee  may also, in its sole discretion,  elect  to
     aggregate  Supplemental Company Contributions  with  Company
     Matching  Contributions to the extent necessary  to  satisfy
     the  ACP discrimination test, provided such aggregation does
     not  itself  result in discrimination.  Notwithstanding  any
     Plan provision to the contrary, any Company contributions so
     aggregated shall be 100% vested, and shall be subject to the
     withdrawal provisions of Section 7.4 as if they are  Before-
     tax Contributions.

4.6  Return of Contributions
     -----------------------

     (a)  Mistake of Fact
          ---------------
          If  the  amount of contribution made to the Plan  by  a
          Participating Company for any Plan Year is in excess of
          the  amount required under Section 4.1, and such excess
          payment  is  due to mistake of fact, the  Participating
          Company  shall  have the right to recover  such  excess
          contribution  within  one  year  after  the  date   the
          contribution is made to the Trustee.  The return  of  a
          contribution shall be permitted hereunder only  if  the
          amount  so  returned (i) is the excess  of  the  amount
          actually  contributed over the amount which would  have
          otherwise  been contributed, (ii) does not include  the
          earnings  attributable to such contribution, and  (iii)
          is   reduced  by  any  losses  attributable   to   such
          contribution.

                                      20
<PAGE>
 
     (b)  Excess Deferrals
          ----------------
          An  excess deferral exists for a Participant if Before-
          tax  Contributions  under this Plan together  with  any
          other  plans  subject  to the deferral  limit  in  Code
          Section  402(g) (for 1996 this limit is $9,500)  exceed
          such dollar limitation for any calendar year.

          In  the  event  an  excess  deferral  exists  in  plans
          maintained by the Participating Company (and Affiliated
          Companies,   if  applicable),  such  excess   deferral,
          adjusted  for investment gains or losses, less  amounts
          previously returned pursuant to subparagraph (c), shall
          be  distributed  no later than April 15  following  the
          calendar year in which the excess deferral occurred.

          In  the  event  an  excess  deferral  exists  in  plans
          maintained   by   the   Company   and   any   unrelated
          employer(s),  and  a  Participant  submits  a   written
          request  for a return of excess deferrals  by  March  1
          following the calendar year in which an excess deferral
          occurs (or any other date authorized by the Committee),
          the  Committee  shall distribute such excess  deferral,
          adjusted  for investment gains or losses, less  amounts
          previously  returned pursuant to subparagraph  (c),  no
          later  than  April  15 following the calendar  year  in
          which  the  excess  deferral  occurred.   Such  written
          request  shall contain information which the  Committee
          may require.

     (c)  ADP Excess Contribution
          -----------------------
          An  ADP  excess  contribution exists  if  contributions
          under   this  Plan  on  behalf  of  Highly  Compensated
          Employees  fail  to  meet the  ADP  test  described  in
          Section 3.4.  Within twelve months after the end of the
          Plan  Year  for which there is an excess, contributions
          which  exceed the ADP limitation, adjusted for earnings
          and  losses, less amounts previously returned  pursuant
          to  subparagraph  (b), shall be distributed  to  Highly
          Compensated   Employees   by   reducing   each   Highly
          Compensated  Employee's  deferral  in  the   order   of
          deferral percentages beginning with the highest.
          
     (d)  ACP Excess Contribution
          -----------------------
          An  ACP  excess  contribution exists  if  contributions
          under   this  Plan  on  behalf  of  Highly  Compensated
          Employees  fail  to  meet the  ACP  test  described  in

          (iii) Any amount reduced from Company Matching Contributions
               not distributed under (ii) above shall be forfeited, with 
               related earnings.  Amounts so forfeited shall be applied 
               to offset future Company Matching Contributions.

     (e)  Contributions in Excess of the Aggregate Limit
          ----------------------------------------------
          In  the event contributions exceed the Aggregate  Limit
          (as  defined  in  Section 4.4),  Participant  unmatched

          using the method described in Section 5.3.

     (g)  Vesting Exception
          -----------------
          Notwithstanding the vesting provisions of Section 8,  a

          (ADP test) in the discretion of the Committee for each Plan Year
          may be recharacterized as After-tax Contributions rather than
          distributed to Participants as provided in Section 4.6(b) and (d)
          above.

     (b)  Recharacterization may be combined with a distribution to
          correct the excess.  If part of the excess is recharacterized,
          the distribution necessary for correction shall be calculated
          after determining the amount of Before-tax Contributions to be
          recharacterized.  Income related to a recharacterized excess
          shall not be treated as an amount recharacterized, but shall
          remain attributed to the applicable Before-tax Contribution
          Account.  

                                      22
<PAGE>
 
          Recharacterized Before-tax Contributions will be eligible for 
          Company Matching Contributions.

     (c)  An amount recharacterized shall be treated as the Company
          contribution  for purposes of Sections 9 Limitation  on
          Contributions and 10 Top Heavy Provisions.   An  amount
          recharacterized before January 1, 1988 shall be treated as an
          After-tax Contribution for purposes of withdrawal under Section
          7.5(b).  Amounts recharacterized after January 1, 1988 will be
          treated as Before-tax Contributions for purposes of hardship
          withdrawal under Section 7.5(d).  Recharacterized amounts shall
          be  treated as Before-tax Contributions for purposes of
          determining Compensation.

          for the taxable year of the hardship withdrawal.

          Notwithstanding  the  foregoing,  a  Participant  whose
          contributions have been suspended for twelve months due
          to  a  hardship  withdrawal shall be deemed  to  be  an
          Eligible  Employee  for purposes of  the  ADP  test  in
          Section 3.4, ACP test in Section 4.3, and multiple  use
          test in Section 4.4.

7.7  Beneficiary Designation
     -----------------------

     If   payments  are  made  to  a  designated  Beneficiary  in
     reasonable  reliance  on  (i) a  written  statement  by  the
     Participant  that  he  or she was not  married,  or  (ii)  a
     spousal  consent that appeared to conform to the requirement
     in  Section 1.5, or (iii) evidence that the spouse could not
     be located at the time of the Beneficiary designation, then,
     to  the  extent  of such payments, the Plan  shall  have  no
     liability to a spouse.

7.8  Loans
     -----

     (a)  General
          -------
          A  Participant who is a "party-in-interest" under ERISA
          may  apply to the Committee for a loan from his or  her
          vested  Accounts, other than the Participant's  Company
          Matching  Contribution Account and other  than  amounts
          invested  in  the Company Stock Fund and the  SpaceLabs
          Stock  Fund.  The Committee has authority to administer
          all  loans, and shall administer loans in a manner that
          does  not  discriminate in favor of Highly  Compensated
          Employees,  officers  or shareholders.   The  Committee
          shall approve all loans that meet the requirements  set
          forth in this section.

          For  recordkeeping purposes, the loan amount  shall  be
          deducted  from  the  Participant's  Accounts   in   the
          following order:

          (i)  from the Rollover Account;

          (ii) from the After-tax Contribution Account; and

          (iii) from the Before-tax Contribution Account.

          In  the event that the amount in an Account exceeds the
          amount  needed  to  fund the loan and  the  Account  is
          invested  in more than one fund, the loan amount  shall
          be  deducted  from the investment funds  in  which  the
          Account is invested (other than the Company Stock  Fund
          and  the  SpaceLabs Stock Fund) in the same  proportion
          that the Account is invested in each fund.

          Only  one loan may be outstanding at any time, and  all
          loans must be secured by the Participant's Accounts.

                                      37
<PAGE>
 
          A  Participant  must  submit  a  loan  request  to  the
          Committee.   Loan  documents,  including  a  promissory
          note,  will be provided to the Participant in  response
          to  the  loan request.  A loan request expires 30  days
          after  it is made.  If the loan request is not approved
          before  it  expires, the Participant may  make  another
          loan  request.   Loan proceeds shall not  be  dispersed
          unless  a  promissory  note, authorization  of  payroll
          deduction   of   loan  repayments,   consent   of   the
          Participant's  spouse  (if any),  and  any  other  loan
          documents  in  the form approved by the  Committee  are
          executed  by  the  Participant  and  the  Participant's
          spouse (if any).

     (b)  Loan Fee
          --------
          A loan fee of $100 will be charged for each loan to pay
          the  Plan's cost of administering loan repayments.  The
          loan fee will be added to the amount of the loan.

     (c)  Hardship Loan
          -------------
          In no event shall a loan be approved unless the loan is
          for the payment of one or more of the hardship expenses
          listed in Section 7.6, and the amount of the loan  does
          not exceed the amount necessary to satisfy the hardship
          expense and to pay the loan fee.

     (d)  Minimum and Maximum Loan Amounts
          --------------------------------
          The minimum amount which may be borrowed is $1,000.  In
          no  event  shall a loan at the time it  is  made,  when
          added  to  the outstanding balance of any  other  loans
          from any Employer-sponsored plan, exceed the lesser of:

          (i)  50 percent of the total vested Account balance as 
               of the Valuation Date immediately preceding the
               date of the loan application;

          (ii) $50,000 reduced by the excess (if any) of:

               (1)  the highest outstanding loan balance during the 
                    one-year period ending on the day before the
                    date on which the current loan is made; over

               (2)  the outstanding loan balance (if any) on the date 
                    on which the current loan is made; or

               (3)  100 percent of the total vested Account balance 
                    invested in funds other than the Company Stock
                    Fund and SpaceLabs Stock Fund.

<PAGE>
 
     (e)  Repayments
          ----------
          The  Participant may elect to repay the loan  over  any
          whole-year  term which does not exceed 5 years;  except
          that  the  term for a loan used to purchase  a  primary
          residence  for  the Participant may be as  long  as  20
          years.

          Once  the loan is made, the repayment term may  not  be
          changed,  provided  however, that the  Participant  may
          elect  to  prepay the full outstanding loan balance  at
          any time during the repayment term.  All loans shall be
          repaid  in  level payments in an amount  no  less  than
          $12.50,  and  except  as  otherwise  provided  in  this
          Section,  shall be made through payroll deduction  each
          pay  period  until the loan is repaid.  Loan repayments
          are  due  each pay period and are considered made  when
          received   by  the  Plan.   Payroll  deductions   shall
          commence  with the first pay period following the  loan
          distribution.   New  financing  or  refinancing  of  an
          outstanding loan is not permitted.

          Loan repayments for a Participant:

          (i)  who is on an approved, unpaid leave of absence;

          (ii) who dies, or

          (iii) whose employment terminates involuntarily due to 
                layoff or reduction in force

          shall  be  suspended,  provided  that  the  period   of
          suspension does not exceed one year and does not exceed
          the maximum repayment period stated above.  Upon return
          to   Service  following  a  period  of  loan  repayment
          suspension,  the  remaining  loan  balance   shall   be
          reamortized  over the remaining loan  period,  and  the
          amount  of  the remaining repayments shall be  adjusted
          accordingly.

          Each repayment shall be credited to each Account of the
          Participant  in the same proportion that  amounts  were
          deducted   from   each  Account  to  fund   the   loan.
          Repayments  will  be invested in the  investment  funds
          (other  than  the Company Stock Fund and the  SpaceLabs
          Stock Fund) in the same manner as new contributions are
          invested.  If new contributions are not being made, the
          Participant  will be required to direct  investment  of
          the loan repayments pursuant to Section 6.

     (f)  Interest Rate
          -------------
          A  fixed  reasonable rate of interest shall be  charged
          for  the term of the loan.  The interest rate shall  be
          the  prime  corporate  lending rate  offered  by  local
          commercial lending institutions on the day on which the
          loan  request is made; provided that the completed loan
          documents  are received by the Committee no later  than
          30   days   after   the  date  of  the  loan   request.
          Notwithstanding   the  preceding   sentence,   if   the
          Committee  determines that such rate is not reasonable,
          the  interest  rate  shall be another  rate  which  the

                                      39
<PAGE>
 
          Committee  determines  is  reasonable  considering  the
          prevailing  interest rate charged on similar commercial
          loans  by  persons  in the business of  lending  money,
          current   economic  conditions,  and  the   facts   and
          circumstances of the loan application.

          In the event the reasonable interest rate determined by
          the  Committee  under  the  preceding  paragraph  would
          violate state usury laws, the Committee shall deny  the
          loan application.

     (g)  Default
          -------
          A loan shall be in default if:

          (i)  a loan repayment remains unpaid for thirty (30) days 
               after the due date for the repayment;

          (ii) the Participant's pay is insufficient during any 
               pay period to cover the entire amount of the loan
               repayment;

          (iii) the Participant revokes the authorization for 
                payroll deduction of loan repayments; or

          (iv) distribution to an alternate payee pursuant to a 
               Qualified Domestic Relations Order under Section
               11.9 of any amount that secures the outstanding
               loan balance as of the date of distribution.

          If  a  loan is in default, the outstanding loan balance
          becomes  immediately due and payable in full,  and  the
          Plan  shall  foreclose  upon the Participant's  Account
          balance  to the extent of the outstanding loan  balance
          as  of  the  earliest date on which the Participant  is
          eligible  for  a  distribution  from  the  Plan.    The
          outstanding  loan  balance  shall  be  treated   as   a
          distribution  for federal income tax purposes  for  the
          year in which the default occurs.

7.9  Directed Rollovers
     ------------------

     (a)  General Rule
          ------------
          A  Participant,  spouse Beneficiary  or  former  spouse
          alternate  payee (each referred to as a  "distributee")
          who is entitled to or elects a lump sum distribution or
          annual installments over a period of less than ten (10)
          years  or obtains a hardship withdrawal may direct  the
          Committee  to  pay  part or all of  the  benefit  to  a
          trustee  or  custodian of another employer's  qualified
          plan  which  accepts  such  directed  rollovers  or  an
          individual  retirement account (IRA),  subject  to  the
          following provisions:

          (i)  a distributee may only direct such a rollover if the
               expected benefit payment during the Plan Year is $200 
               or more;

                                      40
<PAGE>
 
          (ii) a distributee may not request a directed rollover of an
               amount distributed due to the minimum required distribution
               provision under Section 11.6(b);

          (iii) the rollover of a distribution may only be directed to
               no more than two (2) qualified plans, two (2) IRAs, or one (1)
               IRA and one (1) qualified plan;

          (iv) a distributee may direct the rollover of a portion of the
               distribution and elect to receive the remaining portion of a
               distribution only if the rollover amount is at least $200;

          (v)  a distributee may not elect a direct rollover of an
               outstanding loan balance which is treated as distributed upon
               termination of the Participant's employment, or in the event of
               default;

          (vi) a rollover direction regarding installments shall apply to
               all installments, unless the direction is changed by the
               distributee;

          (vii) a spouse Beneficiary or a former spouse alternate payee
               may direct a rollover under the same terms and conditions as a
               Participant, except that a spouse Beneficiary may only direct a
               rollover to an IRA; and

          (viii) a distributee provides the information or documentation
               reasonably requested by the Committee.

     (b)  Notice to Participants
          ----------------------
          The   Committee   shall   furnish   each   Participant,
          Beneficiary   and  alternate  payee  eligible   for   a
          directed  rollover under this Section  with  a  written
          explanation  of  the directed rollover opportunity  and
          related  withholding consequences  of  not  choosing  a
          directed rollover within a reasonable period (at  least
          thirty  (30) but not more than ninety (90) days)  prior
          to  the Annuity Starting Date; provided, however,  that
          the  notice  recipient may waive in writing the  thirty
          (30) day period.

                                    VESTING


8.1  Vesting
     -------

     (a)  Participant Before-tax Contribution Account, After-tax
          ------------------------------------------------------
          Contribution Account and Rollover Account
          -----------------------------------------
          Each    Participant   shall   have   a   100%   vested,
          nonforfeitable   right  to  his   or   her   Before-tax
          Contribution  Account, After-tax  Contribution  Account
          and Rollover Account.

     (b)  Company Matching and Supplemental Contribution Accounts
          -------------------------------------------------------
          Each  Participant  shall earn a vested,  nonforfeitable
          right  to  his  or  her  Company Matching  Contribution
          Account  and Supplemental Company Contribution  Account
          based on his or her Period of Service multiplied by the
          appropriate vesting percentage in accordance  with  the
          following table:

                    Period of Service   Percent Vested
                    -----------------   --------------
                    Less than 1 year    0%
                    1 year              20%
                    2 years             40%
                    3 years             60%
                    4 years             80%
                    5 years or more     100%

          Notwithstanding  the preceding, a Participant  who  had
          completed, as of July 1, 1991, at least three Years  of
          Service  with Interspec, Inc. shall have a 100  percent
          vested  nonforfeitable  right to  his  or  her  Company
          Matching  Contribution Account.  For  purposes  of  the
          preceding  sentence  "Years of Service"  has  the  same
          meaning  as  the  term is defined under the  Interspec,
          Inc. 401(k) Retirement/Savings Plan.

          In addition, each Participant shall have a 100% vested,
          nonforfeitable  right  to his or her  Company  Matching
          Contribution    Account   and   Supplemental    Company
          Contribution Account upon death, becoming Disabled,  or
          attainment  of  his  or  her  Normal  Retirement  Date,
          provided he or she is an Employee on such date.

          In  the  event  the  Participant has received  a  prior
          distribution  from  his  or  her  Company  Matching  or
          Supplemental Contribution Accounts, the vested  portion
          of  the Account balance (including the amount which may
          yet  be restored pursuant to Section 8.2) following the
          distribution shall be determined by application of  the
          following formula:

                                      42
<PAGE>
 
                               X = P(AB+D) - D;

          where  X  equals  the  vested  amount;  P  equals   the
          Employee's  vested  interest in  the  Company  Matching
          Contribution    Account    or   Supplemental    Company
          Contribution   Account  at  the  time   of   subsequent
          distribution; AB equals the balance of the  Account  at
          the  time of subsequent distribution; and D equals  the
          amount previously distributed from the Company Matching
          or Supplemental Contribution Account.

          Notwithstanding  the foregoing, this formula  does  not
          apply   if   the  Participant  has  repaid  the   prior
          distribution  pursuant to Section  8.3(b).   Also,  the
          formula  does  not apply if the prior distribution  may
          not be repaid because the Participant has incurred five
          or  more consecutive one year Periods of Severance,  or
          because five years or more have elapsed since the  date
          of reemployment.

8.2  Forfeitures
     -----------

     If  a Participant terminates Service and is not fully vested
     in his or her Accounts attributable to Company Contributions
     in  accordance  with Section 8.1(b), the  Participant  shall
     forfeit his or her unvested interest in such Accounts as  of
     the  last  day of the month during which his or her  Service
     terminated.   Amounts  held  in  a  Participant's   Accounts
     attributable  to  Company  Contributions  which   are   thus
     forfeited  shall  be  applied first to restore  Accounts  as
     provided  below, and then to reduce subsequent contributions
     by  the  Participant's Participating Company, based  on  the
     Current  Market  Value  of  such  shares  as  of  the   date
     forfeited, where applicable, provided, however, if the  Plan
     should    be   terminated,   or   contributions   thereunder
     permanently  discontinued,  an  amount  not  previously   so
     applied  shall  be  credited on  a  pro-rata  basis  to  the
     Accounts  of  all  Participants in the Company  Stock  Fund.
     Each   year  the  Committee  shall  determine  in  its  sole
     discretion  whether forfeitures shall be applied  to  reduce
     Company Matching Contributions or Supplemental Contributions
     or both.

     If such Participant returns to Service before suffering five
     consecutive  one  year  Periods  of  Severance,  the  amount
     forfeited shall be restored as of the last day of  the  Plan
     Year  in which the Participant returns to Service and repays
     in full any prior distribution, if any, according to Section
     8.3.

     Assets  to  restore amounts forfeited shall be  taken  first
     from  current  forfeitures.  In the event that current  year
     forfeitures  are inadequate to fully reinstate the  Account,
     the  Participating  Company shall  make  a  contribution  in
     addition  to  the contributions required under  Section  4.1
     equal  to  the  balance  necessary to  fully  reinstate  the
     Account.

                                      43
<PAGE>
 
8.3  Reemployment
     ------------

     (a)  Periods of Service
          ------------------
          If  a  Terminated Employee later becomes a  Participant
          again  following reemployment, all Periods  of  Service
          before and after the Period of Severance shall be taken
          into  account  in determining the Participant's  vested
          interest  in  the  Company  Matching  and  Supplemental
          Contribution Accounts established upon reemployment.

     (b)  Repayment
          ---------
          If  a  Participant forfeited a portion of  his  or  her
          Company Matching and Supplemental Contribution Accounts
          upon termination and he or she returns to Service after
          receiving a distribution and prior to incurring a five-
          year Period of Severance, the Participant may elect  to
          repay the amount previously distributed from his or her
          Company    Matching   and   Supplemental   Contribution
          Accounts.  Such Participant may elect to repay  his  or
          her prior distribution before five years after the date
          of   reemployment.   The  forfeited  amount  shall   be
          restored  upon such repayment pursuant to Section  8.2.
          Amounts  repaid  shall  be 100%  vested  and  shall  be
          invested in accordance with Section 6.3.  Such  amounts
          shall   be   held   in   the  Participant's   After-tax
          Contribution Account if they are repaid with  After-Tax
          amounts, and shall be held in the Participant's Before-
          Tax Contribution Account if they are repaid with Before-
          Tax  amounts  transferred or rolled over  from  another
          qualified plan or IRA.

     (c)  Restoration of Forfeitures
          --------------------------
          If  a  Participant forfeited a portion of  his  or  her
          Company Matching and Supplemental Contribution Accounts
          but  did  not  receive  a distribution  of  the  vested
          portion of such Accounts prior to reemployment, and  he
          or  she  returns to Service prior to incurring a  five-
          year Period of Severance, the forfeited amount shall be
          reinstated as of the last day of the Plan Year in which
          reemployment occurs.

8.4  Suspension of Installment Payments
     ----------------------------------

     In  the  event that any person shall resume Service after  a
     previous termination of Service, installment payments  being
     made  to  him (if any) shall be suspended.  In the event  of
     such suspension, the amount held in his Accounts at the time
     of his resumption of Service shall remain to his credit on a
     fully  vested basis, notwithstanding any other provision  in
     the Plan to the contrary.

                          LIMITATION ON CONTRIBUTIONS


9.1  Maximum Annual Contribution to the Plan
     ---------------------------------------

     For  purposes  of  this  Section  8,  the  Company  and  any
     Affiliated Companies shall be considered a single  employer,
     to the extent required by the Code.

     (a)  Primary Rule
          ------------
          Notwithstanding  any  other  Plan  provision   to   the
          contrary,  the  Annual  Additions  to  a  Participant's
          Accounts   in   this   Plan  and  any   other   defined
          contribution plan maintained by the Company  shall  not
          exceed  the lesser of (i) $30,000 (or 25% of  the  Code
          Section  415  defined  benefit  dollar  limitation   if
          greater),    or   (ii)   25%   of   the   Participant's
          Compensation.

     (b)  Annual Additions Defined
          ------------------------
          For  purposes of Section 8, the term "Annual Additions"
          for any Participant in any Plan Year means the sum of:

          (i)  the amount of Company Contributions and Participant
               Before-Tax and After-tax Contributions allocated to a
               Participant's Accounts;

          (ii) forfeitures allocated to the Participant's Accounts; and

          (iii) with respect only to the $30,000 limitation, amounts
               attributable to retiree medical benefits on behalf of 
               a key Employee in a separate account in a welfare
               fund subject to Code Section 419A.

     (c)  Cost-of-Living Adjustment
          -------------------------
          The  $30,000  (or 25% of the Code Section  415  defined
          benefit  dollar limitation if greater) limit prescribed
          above    shall    be   automatically    adjusted    for
          cost-of-living  increases, to the  maximum  permissible
          dollar  limitation  determined by the  Commissioner  of
          Internal  Revenue.   The dollar  amount  applicable  in
          computing  the maximum contribution for any Participant
          shall  be  the dollar amount in effect for the calendar
          year in which the contribution is made.

     (d)  Remedy
          ------
          If  for  any Plan Year the Annual Additions exceed  the
          foregoing limitations because of a reasonable error  in
          determining  the  amount of a Participant's  Before-tax
          Contributions, the Plan Administrator shall  distribute
          the amount of Before-tax Contributions in excess of the
          limits.  If the Annual Additions exceed the limits  for
          any other reason, the Company shall allocate the 

                                      45
<PAGE>
 
          excess to a suspense account.  The suspense account 
          shall be credited with  investment earnings  and losses 
          as of each  Valuation  Date  in  the  same   manner  as  
          Participant Accounts pursuant  to  Section  5.3.   Such  
          suspense account is  for accounting purposes  only  and  
          shall remain in the Trust Fund to be reallocated as provided
          below.   Contents  of  the suspense  account  shall  be
          allocated  to  the  affected Participant's  Account  in
          subsequent   years  when  that  can  be  done   without
          exceeding the limitations of this Section 9.1.  So long
          as  any  amount  remains in the suspense  account,  the
          Company  shall  not contribute to the Plan  any  amount
          which  would  cause  an additional  allocation  to  the
          suspense account.  In the event the Participant  ceases
          to  be  a  Participant  when any amount  remains  in  a
          suspense  account, such amount shall be reallocated  to
          active  Participants as of the end  of  the  Plan  Year
          following  the calendar year in which he or she  ceases
          to  be a Participant.  In the event the Plan terminates
          before any amount remaining in the suspense account has
          been  fully  allocated  to  Participant  Accounts,  the
          balance of the suspense account shall be distributed to
          the Company.

          If  any  Participant is also a participant  in  another
          employee   retirement  plan  that  (a)  is  a   defined
          contribution plan within the meaning of section  414(i)
          of  the Code and (b) is sponsored by the Company or  an
          Affiliated Company, the foregoing limitations shall  be
          applied  on an aggregate basis.  Any reduction required
          to conform to such limitations shall first be made (pro
          rata)  in  contributions by the Participant  under  the
          plans involved; and a pro-rata reduction shall then  be
          made  in  the contributions by the Affiliated Companies
          (including  forfeitures) allocable to  the  Participant
          under the plans involved.

9.2  Additional Limitation Relating to Defined Benefit Plans
     -------------------------------------------------------

     (a)  Primary Rule
          ------------
          For  Participants who participate in this  Plan  and  a
          defined benefit plan maintained by the Company, the sum
          of  (1)  and  (2) below for any calendar year  may  not
          exceed 1.0, as determined by the Committee.

          (i)  The defined benefit plan fraction for any year is 
               equal to the quotient of (i) divided by (ii) below
               expressed as a fraction:

               (1)  The projected annual benefit, (determined by projecting
                    service, but not earnings, to normal retirement age) of 
                    the Participant under the Plan determined as of the close 
                    of the year.

               (2)  The lesser of: (a) 1.25 multiplied by the dollar limitation
                    in effect for defined benefit plans under Section 415 of 
                    the Code for such year, or (b) 1.4 multiplied by 100% of 
                    the Participant's average annual Compensation from the 
                    Company for the consecutive calendar years (not in excess 
                    of three 
 
                                      46
<PAGE>
 
                    such years) during which he was an active Participant in 
                    the Plan and for which such average is highest.

          (ii) The defined contribution plan fraction for any year is equal
               to the quotient of (i) divided by (ii) below expressed as a
               fraction:

               (1)  The sum of the Annual Additions to the Participant's
                    Accounts for the current year, as of the close of the 
                    year, and for all prior years from and after the 
                    Employment Commencement Date.

               (2)  The sum of the lesser of the following amounts for such 
                    year and for each prior year of Service with the Company 
                    (regardless of whether a plan was in existence during 
                    those years): (a) 1.25 multiplied by the dollar 
                    limitation in effect for defined contribution plans 
                    under Section 415 of the Code for such year, or (b) 1.4 
                    multiplied by 25% of a Participant's Compensation for
                    such year.

     (b)  Remedy
          ------      
          If  such sum exceeds 1.0, the Annual Additions to  this
          defined  contribution  Plan shall  be  reduced  to  the
          extent  necessary  to satisfy the limitations  of  this
          section.

                             TOP HEAVY PROVISIONS


10.1 Scope
     -----

     Notwithstanding any Plan provision to the contrary, for  any
     Plan  Year in which the Plan is Top Heavy within the meaning
     of  Section  416(g)  of  the Code, the  provisions  of  this
     Section 10 shall govern to the extent they conflict with  or
     specify  additional  requirements  to  the  Plan  provisions
     governing Plan Years which are not Top Heavy.

10.2 Top Heavy Status
     ----------------

     (a)  Top Heavy
          ---------
          This   Plan  shall  be  "Top  Heavy"  if,  as  of   the
          Determination Date, (1)  the Present Value  of  Accrued
          Benefits  of  Key Employees, or (2)   the  sum  of  the
          Aggregate Accounts of Key Employees under this Plan and
          any plan of an Aggregation Group, exceeds sixty percent
          (60%)  of the Present Value of Accrued Benefits or  the
          Aggregate Accounts of all Participants under this  Plan
          and  any  plan  of an Aggregation Group, determined  in
          accordance  with  Code Section 416(g)  and  regulations
          thereunder.

          The  Present Value of Accrued Benefits and/or Aggregate
          Account  balance of a Participant who was previously  a
          Key Employee but is no longer a Key Employee (or his or
          her  Beneficiary), shall not be taken into account  for
          purposes  of determining Top Heavy status.  Further,  a
          Participant's Present Value of Accrued Benefits  and/or
          Aggregate  Account  balance shall  not  be  taken  into
          account if he or she has not performed services for the
          Affiliated Companies at any time during the  five  year
          period ending on the Determination Date.

     (b)  Super Top Heavy
          ---------------
          This  Plan  shall be "Super Top Heavy" if,  as  of  the
          Determination Date, (1)  the Present Value  of  Accrued
          Benefits  of  Key Employees, or (2)   the  sum  of  the
          Aggregate Accounts of Key Employees under this Plan and
          any  plan  of  an  Aggregation  Group,  exceeds  ninety
          percent  (90%) of the Present Value of Accrued Benefits
          or  the  Aggregate  Accounts of all Participants  under
          this Plan and any plan of an Aggregation Group.

     (c)  Determination Date
          ------------------ 
          Whether  the Plan is Top Heavy for any Plan Year  shall
          be   determined   as   of   the   Determination   Date.
          "Determination  Date" means (a)  the last  day  of  the
          preceding  Plan Year, or (b)  in the case of the  first
          Plan Year, the last day of such Plan Year.

                                      48
<PAGE>
 
     (d)  Valuation Date
          --------------
          "Valuation Date" means, for purposes of determining Top
          Heaviness,  the  Determination  Date  instead  of   the
          meaning set forth in Section 1.

     (e)  Aggregate Account
          -----------------
          "Aggregate   Account"  means,   with   respect   to   a
          Participant, the sum of:

          (i)  his or her account balances as of the Valuation Date;

          (ii) contributions after the Valuation Date due as of the
               Determination Date;

          (iii) distributions prior to the Valuation Date, made during
               the Plan Year that contains the Determination Date and the 
               four preceding Plan Years.

     (f)  Present Value of Accrued Benefits
          ---------------------------------
          The "Present Value of Accrued Benefits" with respect to
          a   defined  benefit  plan  shall  be  based  upon  the
          Participant's   accrued  benefits  and  the   actuarial
          assumptions as determined under the provisions  of  the
          applicable defined benefit plan.

     (g)  Key Employee
          ------------
          "Key  Employee"  means an Employee or  former  Employee
          (and  his or her Beneficiaries) who, at any time during
          the  Plan Year containing the Determination Date or any
          of the four preceding Plan Years, is included in one of
          the  following  categories as  within  the  meaning  of
          Section   416(i)(l)   of  the  Code   and   regulations
          thereunder:

          (i)  an  officer of the Company whose annual  aggregate
               Compensation from the Affiliated Companies exceeds
               50% of the dollar limitation under Code Section
               415(b)(1)(A) ($62,500 for the Plan Year ending in
               1997), provided that no more than 50 Employees shall
               be considered officers, or if less, the greater of
               10% of the Employees or three (3),

          (ii) one of the ten (10) Employees owning the largest 
               interest in the Company who owns more than a 0.5%
               interest of the Company, and whose annual aggregate
               Compensation from the Affiliated Companies exceeds
               the dollar limitation under Section 415(c)(1)(A) of
               the Code ($30,000 for the Plan Year ending in 1997).

          (iii) an Employee who owns more than 5% of the Company, or

                                      49
<PAGE>
 
          (iv) an Employee who owns more than 1% of the Company with annual
               aggregate Compensation from the Affiliated Companies that 
               exceeds $150,000.

     (h)  Aggregation Group
          -----------------
          "Aggregation Group" means the group of plans that  must
          be   considered  as  a  single  plan  for  purposes  of
          determining whether the plans within the group are  Top
          Heavy  (Required Aggregation Group), or  the  group  of
          plans  that may be aggregated for purposes of Top Heavy
          testing    (Permissive   Aggregation    Group).     The
          Determination Date for each plan must fall  within  the
          same calendar year in order to aggregate the plans.

          (i)  The Required Aggregation Group includes each plan of the
               Affiliated Companies in which a Key Employee is a participant in
               the Plan Year containing the Determination Date or any of the
               four preceding Plan Years, and each other plan of the Affiliated
               Companies which, during this period, enables any plan in which a
               Key Employee participates to meet the minimum participation
               standards or non-discriminatory contribution requirements of 
               Code Sections 401(a)(4) and 410.

          (ii) A Permissive Aggregation Group may include any plan
               sponsored by an Affiliated Company, provided the group as a 
               whole continues to satisfy the minimum participation standards 
               and non-discriminatory contribution requirements of Code 
               Sections 401(a)(4) and 410.

          Each  plan  belonging to a Required  Aggregation  Group
          shall  be  deemed  Top  Heavy,  or  non-Top  Heavy   in
          accordance  with the group's status.  In  a  Permissive
          Aggregation  Group that is determined  Top  Heavy  only
          those plans that are required to be aggregated shall be
          Top  Heavy.  In a Permissive Aggregation Group that  is
          not Top Heavy, no plan in the group shall be Top Heavy.

10.3 Minimum Contribution
     --------------------

     (a)  General Rule
          ------------
          For  any Plan Year in which the Plan is Top Heavy,  the
          total  Company contribution under Section 4.1  and  any
          forfeitures  allocated  to  any  non-key  Participant's
          account shall not be less than 3% of such Participant's
          Compensation.  Participant contributions under  Section
          4.1(a) are not considered when determining whether this
          3% requirement is satisfied.  However, in the event the
          Company contributions and forfeitures allocated to each
          Key  Employee's account do not exceed 3% of his or  her
          Compensation,    such   Company    contributions    and
          forfeitures for non-Key Employees are only required  to
          equal the highest percentage of Compensation, including
          Participant  Before-tax  Contributions  under   Section

                                      50
<PAGE>
 
          4.1(a),  allocated to any Key Employee's  accounts  for
          that  Plan  Year  under any defined contribution  plans
          sponsored by the Affiliated Companies.

          The  minimum contribution must be made on behalf of all
          non-Key  Participants who are employed on the last  day
          of  the  Plan Year including non-Key Employees who  (1)
          failed  to complete a year of service, or (2)  declined
          to  make  any  mandatory contributions to the  Plan  or
          enter a salary deferral agreement.

     (b)  Special Two Plan Rule
          ---------------------
          Where this Plan and a defined benefit plan belong to an
          Aggregation  Group that is determined  Top  Heavy,  the
          minimum contribution required under paragraph (a) above
          shall be increased to 5%.

10.4 Limitation to Annual Additions in Top Heavy Plan
     ------------------------------------------------

     For  any  Top Heavy Plan Year in which the Company does  not
     make  the extra minimum allocation provided below, 1.0 shall
     replace  the  1.25 factor found in the denominators  of  the
     defined benefit and defined contribution plan fractions  for
     purposes  of calculating the combined limitation on benefits
     under  a  defined  benefit  and  defined  contribution  plan
     pursuant to Section 415(e) of the Code (see Section 9.3).

     If  this Plan is Top Heavy, but is not Super Top Heavy,  the
     above  referenced fractions shall remain unchanged  provided

          Unless  a Participant elects otherwise, the payment  of
          benefits shall commence no later than 60 days after the

     (c)  Right to Request Review
          -----------------------
          Any  person who has had a claim for benefits denied  by
          the  Committee, or is otherwise adversely  affected  by
          action  of  the  Committee, shall  have  the  right  to
          request review by the Committee.  Such request must  be
          in  writing, and must be made within 60 days after such
          person  is  advised  of  the  Committee's  action.   If
          written  request  for review is not  made  within  such
          60-day  period, the Claimant shall forfeit his  or  her
          right  to  review.  The Claimant or a  duly  authorized

          extension  within  60 days following  the  request  for
          review.   A copy of the decision shall be furnished  to
          the Claimant.  The decision shall set forth its reasons
          and  pertinent plan provisions on which  it  is  based.
          The  decision  shall  be final  and  binding  upon  the
          Claimant  and  the  Committee  and  all  other  persons
          involved.

11.8 Plan Administration - Miscellaneous
     -----------------------------------

     (a)  Limitations on Assignments
          --------------------------
          Benefits  under  the  Plan may not be  assigned,  sold,
          transferred, or encumbered, and any attempt  to  do  so
          shall  be  void.   The  interest of  a  Participant  in
          benefits  under the Plan shall not be subject to  debts
          or  liabilities of any kind and shall not be subject to
          attachment, garnishment or other legal process,  except
          as  provided  in  Section  11.9  relating  to  Domestic
          Relations Orders, or otherwise permitted by law.

          Notwithstanding   the   above,   any   Participant   or
          Beneficiary who is to receive a distribution  from  the
          Plan  in  shares of Company Stock may, subject  to  the
          provisions  or Treasury  Regulations  Section 1.401(a)-
          13(e), make a revocable election that such stock be issued
          jointly (with the right of survivorship) to him and his
          spouse; provided, however, that no such election  shall
          be  effective  until the Participant's or Beneficiary's
          spouse   files  a  written  acknowledgment   with   the
          Committee,  in  accordance  with  Treasury  Regulations
          Section 1.401(a)-13(e)(2),   stating that  such  spouse  
          has  no enforceable   right in, or to, any Plan benefit  
          (except to the extent of payments actually received).

                                      56

          Fund,  or  any part thereof, or under the Plan,  except
          as,  and only to the extent, expressly provided for  in
          the  Plan.  Neither the establishment of the Plan,  the
          establishment of Participant Accounts nor any action of
          the Company or the Committee shall be held or construed
          to  confer upon any person any right to be continued as
          an  Employee, or, upon dismissal, any right or interest
          in  the Trust Fund other than as herein provided.   The
          Company  expressly reserves the right to discharge  any
          Employee at any time.

     (d)  Governing Law
          -------------
          This   Plan  shall  be  construed  in  accordance  with
          applicable  federal law and the laws of  the  State  of
          Washington.

     (e)  Disclosure to Participants
          --------------------------
          Each  Participant  shall  be  advised  of  the  general
          provisions  of  the  Plan  and,  upon  written  request
          addressed  to  the  Committee, shall be  furnished  any
          information   requested  regarding  the   Participant's
          status, rights and privileges under the Plan as may  be
          required by law.

     (f)  Income Tax Withholding Requirements
          -----------------------------------
          Any retirement benefit payment made under the Plan will
          be  subject  to  any applicable income tax  withholding
          requirements.   For this purpose, the  Committee  shall
          provide  the  Trustee with any information the  Trustee
          needs to satisfy such withholding obligations and  with
          any   other   information  that  may  be  required   by
          regulations promulgated under the Code.

     (g)  Severability
          ------------
          If  any provision of this Plan shall be held illegal or
          invalid  for any reason, such determination  shall  not
          affect  the  remaining provisions of  this  Plan  which
          shall  be  construed  as  if said  illegal  or  invalid
          provision had never been included.

     (h)  Facility of Payment
          -------------------
          In  the  event  any benefit under this  Plan  shall  be
          payable to a person who is under legal disability or is
          in  any  way incapacitated so as to be unable to 

                                      57
<PAGE>
 
          manage his  or her financial affairs, the Committee may 
          direct payment of such benefit to a duly appointed guardian,
          committee or other legal representative of such  person
          or   in   the   absence   of  a   guardian   or   legal
          representative, to a custodian for such person under  a
          Uniform  Gift to Minors Act or to any relative of  such
          person by blood or marriage, for such person's benefit.
          Any  payment  made  in  good  faith  pursuant  to  this
          provision  shall  fully discharge the Company  and  the
          Plan of any liability to the extent of such payment.

     (i)  Correction of Errors
          --------------------
          Any Company contribution to the Trust Fund made under a
          mistake   of  fact  (or  investment  proceed  of   such
          contribution if a lesser amount) shall be  returned  to
          the  Company  within  one year  after  payment  of  the
          contribution.

          In  the  event  an  incorrect  amount  is  paid  to   a
          Participant or Beneficiary, any remaining payments  may
          be  adjusted  to correct the error.  The Committee  may
          take such other action it deems necessary and equitable
          to correct any such error.

     (j)  Missing Persons
          ---------------
          In  the  event a distribution is required  to  commence
          under  Section  7.2 and the Participant or  Beneficiary
          cannot  be located, the Participant's Account shall  be
          forfeited  on  the last day of the Plan Year  following
          the  Plan  Year in which distribution was  supposed  to
          commence.   Such  forfeiture shall be  used  to  reduce
          Company Matching Contributions.

          If   the  affected  Participant  or  Beneficiary  later
          contacts  the  Company, his or  her  Account  shall  be
          reinstated  and distributed as soon as practical.   The
          Company shall reinstate the amount forfeited by  making
          a   special  contribution  equal  to  such  amount  and
          allocating   it   to  the  affected  Participant's   or
          Beneficiary's Account.  Such reinstatement shall not be
          considered  an  annual addition  for  purposes  of  the
          limitations  on contributions on benefits  pursuant  to
          Code Section 415.

          Prior  to  forfeiting any Account,  the  Company  shall
          attempt  to  contact the Participant or Beneficiary  by
          return  receipt mail at his or her last  known  address
          according  to the Company's records, and by the  letter
          forwarding   services  offered  through  the   Internal

11.9 Domestic Relations Orders
     -------------------------

     Notwithstanding  any  Plan  provisions  to   the   contrary,
     benefits  under the Plan may be paid to someone  other  than
     the  Participant  or  Beneficiary pursuant  to  a  Qualified
     Domestic Relations Order, in accordance with Section  414(p)
     of  the  Code.  A Qualified Domestic Relations  Order  is  a
     judgment, decree, or order ("Order") (including approval  of
     a property settlement agreement) that:

     (a)  relates to the provision of child support, alimony payments
          or marital property rights to a spouse, former spouse, child or
          other dependent of a Participant;

     (b)  is  made  pursuant  to a state domestic  relations  law
          (including a community property law);

     (c)  creates or recognizes the existence of an alternate payee's
          right to, or assigns to an alternate payee the right to, receive
          all or a portion of the benefits payable to a Participant under
          the Plan;

     (d)  specifies the name and last known address of the Participant
          and each alternate payee;

     (e)  specifies the amount or method of determining the amount of
          benefit payable to an alternate payee;

     (f)  names each plan to which the order applies;

     (g)  does not require any form, type or amount of benefit not
          otherwise provided under the Plan;

     (h)  does not conflict with a prior Domestic Relations Order that
          meets the other requirements of this section.

     Payment  to  an  alternate  payee pursuant  to  a  Qualified
     Domestic  Relations Order shall commence within a reasonable
     time  following  qualification of the Order.   Such  payment
     shall  commence  regardless  of  the  Participant's  age  or
     whether the Participant Terminates or continues employment.

     The  Committee  shall determine whether an order  meets  the
     requirements  of  this section within  a  reasonable  period
     after  receiving an order.  The Committee shall  notify  the
     Participant and any alternate payee that an order  has  been
     received.  Any amounts which are to be paid pursuant to  the
     order, during the period while its qualified status is being
     determined,  shall be held in a separate account  under  the
     Plan  for any alternate payee pending determination that  an
     order  meets  the requirements of this section.   If  within
     eighteen   months   after  such  a   separate   account   is
     established,  the  order has not been  determined  to  be  a
     qualified Order, the amount in the separate account shall be
     distributed  to the individual who would have been  entitled
     to such amount if there had been no order.

                                    59

11.10 Plan Qualification
      ------------------

     Any  modification  or  amendment of the  Plan  may  be  made
     retroactive,  as necessary or appropriate, to establish  and
     maintain a "qualified plan" pursuant to Section 401  of  the
     Code, and ERISA and regulations thereunder and exempt status
     of the Trust Fund under Section 501 of the Code.

11.11 Deductible Contribution
      -----------------------

     Notwithstanding  anything  herein  to  the   contrary,   any
     contribution by the Company to the Trust Fund is conditioned
     upon  the  deductibility of the contribution by the  Company
     under  the  Code  and, to the extent any such  deduction  is
     disallowed,  the  Company may within one  year  following  a
     final determination of the disallowance, demand repayment of
     such  disallowed contribution and the Trustee  shall  return
     such  contribution less any losses attributable  thereto  to
     the Company within one year following the disallowance.

11.12 Voting of Company Stock and SpaceLabs Medical, Inc. Stock
      ---------------------------------------------------------

     Before each annual or special meeting of the stockholders of
     the  Company,  the Company shall cause to be  sent  to  each
     Participant having shares in the Company Stock Fund  or  the
     SpaceLabs  Stock  Fund  a  copy of  the  proxy  solicitation
     material   therefor,  together  with   a   form   requesting
     confidential instructions to the Trustee on how to vote  the
     number of shares of common stock in either Fund credited  to
     such  Participant.   Upon receipt of such  instructions  the
     Trustee  shall  vote  the  shares of  stock  as  instructed.
     Instructions  received from individual Participants  by  the
     Trustee shall be held in the strictest confidence and  shall
     not  be  divulged  or  released  to  any  person,  including
     officers  or  employees  of any Company  or  any  Affiliated
     Company.  The Trustee shall vote all shares of Company Stock
     and SpaceLabs Medical, Inc. stock held by it under the Plan,
     for  which voting instructions shall not have been  received
     for  or against proposals submitted, in the same proportions
     as  the  shares for which instructions are received  by  the
     Trustee from Participants.

     In the event of a tender or exchange offer for Company Stock
     or  SpaceLabs  Medical, Inc. common stock, the  response  to
     such offer by the Trustee shall be determined as though  the
     decision  constitutes  the exercise  of  voting  rights,  as
     described in this Section 11.12, except that any shares with
     respect   to  which  instructions  are  not  received   from
     Participants or Beneficiaries shall not be tendered  by  the
     Trustee.

                           AMENDMENT AND TERMINATION


12.1 Amendment and Termination
     -------------------------

     It  is  the Company's intention that the Plan will  continue
     indefinitely; however, the Company, by action of  its  Board
     of  Directors, shall have the right to amend, terminate,  or
     partially  terminate this Plan at any time  subject  to  any
     advance  notice or other requirements of ERISA.  Should  the
     Board  amend  the Plan, such amendment shall  apply  to  all
     Participating  Companies as of the date that  the  amendment
     applies  to  the  Company.   A  participating  Company  may,
     however,  adopt for its employees a different definition  of
     "Eligible  Employee" than is contained in  Section  1  or  a
     different  standard of participation than  is  contained  in
     Section   2,  by  filing  with  the  Committee  a  certified
     resolution  of  its  Board of Directors, provided,  however,
     that such resolution shall become effective only if approved
     by  the Committee.  No amendment of the Plan shall have  the
     effect  of  providing that the funds held in  trust  by  the
     Trustee or the earnings thereon may be used for, or diverted
     to, purposes other than the Plan.

12.2 Consolidation or Merger
     -----------------------

     In  the  event the Plan's assets and liabilities are  merged
     into,  transferred  to  or otherwise consolidated  with  any
     other retirement plan, then such must be accomplished so  as
     to   ensure  that  each  Participant  would  (if  the  other
     retirement   plan   then  terminated)  receive   a   benefit
     immediately  after  the merger, transfer  or  consolidation,
     which is  equal to or greater than the benefit the  partici-
     pant  would have been entitled to receive immediately before
     the  merger, transfer or consolidation (as if the  Plan  had
     then terminated).  This provision shall not be construed  as
     limiting  the powers of the Company to appoint  a  successor
     Trustee.

     Subject  to the foregoing, if any Affiliated Company becomes
     a  Participating Company, and such Company had a thrift plan
     or similar plan or participated in a similar plan of another
     organization, the Board, with the approval of the Affiliated
     Company, may merge such plan into the Plan and thereupon all
     employees of the Affiliated Company who were members of such
     plan shall automatically become Participants hereunder,  and
     all  amounts  in  the  accounts of  such  employees  of  the
     Affiliated Company shall become accounts under this Plan, in
     the  manner determined by the Committee; provided,  however,
     that  amounts  so transferred shall not be  subject  to  the
     limitations  imposed  under  Sections  3  and  4   on   such
     contributions and no Participating Company shall be required
     or permitted to make company matching contributions based on
     any  of  the  amounts  transferred to the  Plan  under  this
     paragraph.

     If  a Participating Company maintains a trust that qualified
     as  an  exempt trust under Section 501(a) of the Code  as  a
     part   of   a   qualified  profit-sharing  plan   to   which
     contributions  have  been permanently discontinued  and  all
     rights  under the trust have vested in employees and  former
     employees  of  the  Participating  Company,  

                                      61
<PAGE>
 
     the  board   of directors of the Participating Company, with 
     the consent of the  Board,  may merge  such  trust  into the 
     Trust  under  the   Plan  and  thereupon  all  employees  of  
     such    Participating   Company   and  employees  of  other 
     Participating Companies  who had   a   vested   interest  in   
     the  merged   trust  shall automatically become Participants 
     in the Plan but solely for the  purposes  of  investing  the 
     amounts so  transferred  and distributing  such  amounts  to 
     such  employees  as   hereinafter  set  forth  in  the Plan.  
     The  amounts  so   transferred  on  behalf  of  each   such 
     employee shall be invested in such funds as he shall direct,  
     under  the  provisions  of    Section  6.1.     Any amounts  
     transferred   under   this  paragraph   shall    constitute
     "Special  Contributions."  Under no circumstances  will  any
     Participating  Company  be required  or  permitted  to  make
     company  matching contributions to the Plan based on Special
     Contributions.   Special  Contributions  and  any   earnings
     thereon  may  not be withdrawn by a Participant  until  such
     time  as  the  Participant ceases to be  an  Employee  of  a
     Participating  Company on account of death,  retirement,  or
     other  voluntary or involuntary termination  of  employment;
     provided,  however, that a full withdrawal of  such  Special
     Contributions  and  earnings may be made  by  a  Participant
     after attainment of age 59 1/2, if he shall at the same time
     make  a  full withdrawal of all his interest in  this  Plan.
     Subject  to the foregoing, all such distributions  shall  be
     made in accordance with the provisions of this Plan.

12.3 Termination of the Plan
     -----------------------

     The  termination of the Plan shall not cause or  permit  any
     part of the Trust Fund to be diverted to purposes other than
     for  the exclusive benefit of the Participants, or cause  or
     permit  any portion of the Trust Fund to revert to or become
     the  property  of  the  Company at any  time  prior  to  the
     satisfaction  of  all  liabilities  with  respect   to   the
     Participants.

     Upon  termination of this Plan, the Committee shall continue
     to  act  for  the  purpose of complying with  the  preceding
     paragraph  and shall have all power necessary or  convenient
     to  the  winding  up and dissolution of the Plan  as  herein
     provided.   While so acting, the Committee shall be  in  the
     same status and position with respect to other persons as if
     the Plan remained in existence.

12.4 Allocation of the Trust Fund on Termination of Plan
     ---------------------------------------------------

     In  the  event of a complete or partial termination  of  the
     Plan, or upon complete discontinuance of contributions under
     the  Plan,  with respect to all Participants or a  specified
     group  or groups of Participants, the Trustee shall allocate
     and segregate a proportionate interest in the Trust Fund for
     the benefit of affected Participants.

     All  Accounts accrued by the affected Participants shall  be
     100%  vested  and  non-forfeitable.   The  Committee   shall
     direct the Trustee to allocate the assets of the Trust  Fund
     to those affected Participants.

     In  the  event  that after the termination of the  Plan  the
     Board  shall  determine that continuance of  the  investment
     funds  is not in the best interest of the Participants,  the
     Company may liquidate the funds and the Trustee shall  apply
     the  proceeds to payment to each Participant and Beneficiary
     of  the value of his or her Accounts.  

                                      62
<PAGE>
 
     Such payment shall be made, in the discretion of the Committee, 
     either wholly or in part by the purchase of non-transferable  
     annuity contracts or by lump-sum payments.

12.5 Partial Termination
     -------------------

     If  at  any time the Plan is terminated with respect to  any
     group of Employees under such circumstances as to constitute
     a  partial  termination of the Plan within  the  meaning  of
     Section 411(d)(3) of the Code, the amounts held in the funds
     that are allocable to such Employees shall be segregated  by
     the Trustee as a separate plan.  The funds thus allocated to
     such  separate plan shall be applied for the benefit of such
     Employees in the manner described in Section 12.4.

                                    FUNDING


13.1 Contributions to the Trust Fund
     -------------------------------

     As  a  part of this Plan the Company shall maintain a  Trust
     Fund.    From   time  to  time,  the  Company   shall   make
     contributions to the Trust Fund in accordance  with  Section
     4.

13.2 Trust Fund for Exclusive Benefit of Participants
     ------------------------------------------------

     The Trust Fund is for the exclusive benefit of Participants.
     Except   as   provided   in   Sections   4.6   (Return    of
     Contributions), 11.9 (Domestic Relations Orders)  and  11.11
     (Deductible  Contribution), no portion  of  the  Trust  Fund
     shall  be diverted to purposes other than this or revert  to
     or  become the property of the Company at any time prior  to
     the  satisfaction  of all liabilities with  respect  to  the
     Participants.

13.3 Trustee
     -------

     As  a  part  of this Plan, the Company has entered  into  an
     agreement with a Trustee who is designated by the  Board  of
     Directors.   The Company has the power and duty  to  appoint
     the  Trustee  and  it  shall have the power  to  remove  the
     Trustee  and appoint successors at any time.  As a condition
     to exercising its power to remove any Trustee hereunder, the
     Company  must first enter into an agreement with a successor
     Trustee.  The Committee may delegate the authority to direct
     the  investment of all or a portion of the Trust Fund to the
     Trustee.

13.4 Investment Manager
     ------------------

     The  Committee  has the power to appoint, remove  or  change
     from  time  to  time  an Investment Manager  to  direct  the
     investment of all or a portion of the Trust Fund held by the
     Trustee.   For purposes of this section "Investment Manager"
     shall mean any fiduciary (other than the Trustee) who:

     (a)  has the power to manage, acquire, or dispose of any asset of
          the Plan;

     (b)  is either

          (i)  registered as an investment adviser under the Investment
               Advisers Act of 1940; or

          (ii) is a bank; or

          (iii) is an insurance company qualified under the laws of
               more than one state to perform the services described in
               subparagraph (a); and

                                      64
<PAGE>
 
     (c)  has  acknowledged in writing that he, she or  it  is  a
          fiduciary with respect to the Plan.

                                  FIDUCIARIES


14.1 Limitation of Liability of the Company and Others
     -------------------------------------------------

     To  the  extent permitted by law, no Participant shall  have
     any  claim against the Company, or the Committee, or against
     their    directors,    officers,    members,    agents    or
     representatives, for any benefits under the Plan,  and  such
     benefits  shall be payable solely from the Trust  Fund;  nor
     shall  the  Company, nor the Committee or  their  directors,
     officers,  members,  agents  or  representatives  incur  any
     liability to any person for any action taken or suffered  or
     omitted to be taken by them under the Plan in good faith.

14.2 Indemnification of Fiduciaries
     ------------------------------

     In   order   to  facilitate  the  recruitment  of  competent
     fiduciaries,  the  Company  adopting  this  Plan  agrees  to
     provide  the  indemnification  as  described  herein.   This
     provision  shall apply to Employees who are considered  Plan
     fiduciaries including without limitation, Committee members,
     any agent of the Committee, or any other officers, directors
     or Employees.  Notwithstanding the preceding, this provision
     shall not apply and indemnification will not be provided for
     any  Trustee or Investment Manager appointed as provided  in
     this Plan.

14.3 Scope of Indemnification
     ------------------------

     The  Company  agrees to indemnify an Employee  fiduciary  as
     described above for all acts taken in good faith in carrying
     out his or her responsibilities under the terms of this Plan
     or  other  responsibilities imposed upon such  fiduciary  by
     ERISA.   This  indemnification for all acts is intentionally
     broad but shall not provide indemnification for embezzlement
     or  diversion of Plan assets for the benefit of the Employee
     fiduciary.    The  Company  agrees  to  indemnify   Employee
     fiduciaries  described herein for all expenses of  defending
     an  action  by  a  Participant,  Beneficiary  or  government
     entity,  including all legal fees for counsel selected  with
     the  consent of the Company and other costs of such defense.
     The  Company  will also reimburse an Employee fiduciary  for
     any   monetary   recovery  in  any  court   or   arbitration
     proceeding.   In  addition, if the claim is settled  out  of
     court with the concurrence of the Company, the Company  will
     indemnify  an Employee fiduciary for any monetary  liability
     under  said  settlement.  The Company shall have the  right,
     but  not  the  obligation, to conduct the  defense  of  such
     persons  in  any  proceeding  to  which  this  Section  14.3
     applies.  The Company may satisfy its obligations under this
     Section 14.3 in whole or in part through the purchase  of  a
     policy   or   policies  of  insurance  providing  equivalent
     protection.

                                 PARTICIPATION


4.1  Retirement Plan Participants
     ----------------------------

     Each participant in the Retirement Plan whose benefits thereunder are
     limited by (a) the dollar limitation on compensation that may be taken into
     account under the plan of Section 401(a)(17) of the Code and/or (b) the

                                   BENEFITS


5.1  Supplemental Pension Benefits
     -----------------------------

     Upon the Retirement of a Participant, the Company shall pay to such
     Participant supplemental pension benefits which when combined with the
     amounts he or she is entitled to receive under the Retirement Plan shall
     equal the retirement pension benefits which would have been payable to the
     Participant had the Retirement Plan's formula been applied without regard
     to the limitations of Sections 401(a)(17) and 415 of the Code.

     For years before calendar year 1994, the supplemental pension benefits for
     a Participant who received salesman commissions or service
     commissions/incentives during the calendar year shall be determined, as to
     that year, by disregarding any such commissions and incentives which exceed
     the dollar limitation of Section 401(a)(17) of the Code.

     For all years subsequent to calendar year 1993, the supplemental pension
     benefits for a Participant who is not the Chief Executive Officer or one of
     the other four most highly compensated executive officers of the Company
     who were serving as executive officers at the end of the last completed
     fiscal year, as specified in Item 401 of Regulation S-K of the Securities
     and Exchange Act of 1934 and reported in the Company's proxy statement for
     the applicable year (the "Five Highest Compensated Officers") shall be
     determined, as to such years subsequent to 1993, by disregarding any
     Earnings which are in excess of the average of the Earnings of the Five
     Highest Compensated Officers for such year.

     Notwithstanding the above, in the case of a Participant who is not entitled
     to a benefit under the Retirement Plan, the Participant shall not be
     entitled to a benefit under this Plan.

5.2  Spouse's Death Benefit
     ----------------------

     Upon the death of a Participant prior to Retirement, the Company shall pay
     to the Surviving Spouse (if any) of such Participant a death benefit which
     when combined with the death benefit which he or she is entitled to receive
     under the Retirement Plan shall equal the death benefit that would have
     been payable to the Surviving Spouse had the Retirement Plan's benefit
     provisions been applied as provided in Section 5.1 above.

5.3  Disability Benefits
     -------------------

     In the event a Participant becomes Disabled, the Company shall pay to such
     Participant supplemental pension benefits which when combined with the
     amounts he or she is entitled to receive under the Retirement Plan shall
     equal the retirement pension benefits which would have been payable to the
     Participant had the Retirement Plan's formula been applied without regard
     to the limitations of Sections 401(a)(17) and 415 of the Code.

     selected by the Participant under the Retirement Plan. Upon the death of a
     Participant, the Company shall pay any death benefit provided in Section 5
     to the Surviving Spouse in the same form of payment which death benefits
     under the Retirement Plan are payable to the Surviving Spouse.

                              GENERAL PROVISIONS


7.1  Unfunded Obligation
     -------------------

     The supplemental benefits to be paid to Participants or their Surviving
     Spouses pursuant to this Plan are unfunded obligations of the Company, and
     shall, until actual payment, continue to be an obligation against the
     general funds of the Company. The Company is not required to segregate any
     monies from its general funds, or to create any trusts, or to make any
     special deposits with respect to these obligations. Nothing contained
     herein shall be deemed to create a trust of any kind or create any
     fiduciary relationship. To the extent that any person acquires a right to
     receive payments from the Company under this Plan, such right shall be no
     greater than the right of any unsecured general creditor of the Company.

7.2  Nonassignment
     -------------

     The right of a Participant or his or her Surviving Spouse to the payment of
     any amounts under the Plan may not be assigned, transferred, pledged or
     encumbered nor shall such right or other interest be subject to attachment,
     garnishment, execution or other legal process.

7.3  No Right to Continued Employment
     --------------------------------

     Nothing in the Plan shall be construed to confer upon any Participant any
     right to continued employment with the Company or a Subsidiary, nor
     interfere in any way with the right of the Company or a Subsidiary to
     terminate the employment of such Participant at any time without assigning
     any reason therefor.

7.4  Withholding Taxes
     -----------------

     Appropriate payroll taxes shall be withheld from cash payments made to
     Participants pursuant to this Plan.

7.5  Termination and Amendment
     -------------------------

     The Board of Directors of the Company reserves the power at any time to
     terminate this Plan and delegates to the Compensation Committee the power
     to otherwise amend any portion of the Plan other than this Section 7.5;
     provided, however, that no such action shall adversely affect the right of
     any Participant (or Surviving Spouse) to a benefit to which he or she has
     become entitled under the Plan. Notice of termination or material amendment
     of the Plan shall be given in writing to each Participant.

     If the Plan is terminated, Participants and Surviving Spouses who have
     accrued benefits under the Plan as of the date of termination will receive
     payment of such benefits at the times specified in the Plan.

                                       8
<PAGE>
 
7.6  ERISA Exemption
     ---------------

     The portion of this Plan providing benefits in excess of the limitations of
     Section 415 of the Code is intended to qualify for exemption from the
     Employee Retirement Income Security Act of 1974 ("ERISA") as an unfunded
     excess benefit plan under Sections 3(36) and 4(b)(5) of ERISA. The portion
     of this Plan providing benefits in excess of the limitation of Section
     401(a)(17) of the Code is intended to qualify for exemption from Parts II,
     III, and IV of ERISA as a plan maintained primarily for the purpose of
     providing deferred compensation for a select group of management or highly
     compensated employees under Sections 201(2), 301(a)(3) and 401(a)(1) of
     ERISA.

7.7  Applicable Law
     --------------

     The Plan shall be construed and governed in accordance with the laws of the
     State of Washington.

5.1  Supplemental Pension Benefits
     -----------------------------
     Upon the Retirement of a Participant, the Company shall pay to such
     Participant supplemental pension benefits which when combined with the
     amounts he or she is entitled to receive under the Retirement Plan and the
     Supplemental Benefit Plan A (if any) shall equal the retirement pension
     benefits which would have been payable to the Participant had the
     Retirement Plan's formula been applied without regard to the limitations of
     Sections 401(a)(17) and 415 of the Code.
     
     For years before calendar year 1994, the supplemental pension benefits for
     a Participant who received a salesman commissions or service
     commissions/incentives during the calendar year shall be determined, as to
     that year, by disregarding any such commissions and incentives which exceed
     the dollar limitation of Section 401(a)(17) of the Code.
     
     For all years subsequent to calendar year 1993, the supplemental pension
     benefits for a Participant who is not the Chief Executive Officer or one of
     the other four most highly compensated executive officers of the Company
     who were serving as executive officers at the end of the last completed
     fiscal year, as specified in Item 401 of Regulation S-K of the Securities
     and Exchange Act of 1934 and reported in the Company's proxy statement for
     the applicable year (the "Five Highest Compensated Officers") shall be
     determined, as to such years subsequent to 1993, by disregarding any
     Earnings which are in excess of the average of the Earnings of the Five
     Highest Compensated Officers for such year.
     
     Effective January 1, 1992, supplemental pension benefits for a Participant
     who received a Management Incentive Compensation Plan (MICP) award for
     performance during the 1992 calendar year shall be determined as though the
     1992 MICP award is included in Earnings for the 1993 calendar year.
     
     Notwithstanding the above, in the case of a Participant who is not entitled
     to a benefit under the Retirement Plan, the Participant shall not be
     entitled to a benefit under this Plan except as provided under Section 5.2
     below.

5.2  Other Supplemental Pension Benefits
     -----------------------------------
     The Compensation Committee in its discretion may establish other
     supplemental pension benefits and designate the Participants who will be
     entitled to receive such benefits. Any such additional supplemental pension
     benefits shall be described in an Appendix to this Plan, and, unless
     otherwise specified in such Appendix, shall be payable as provided in
     Article 6.

5.3  Spouse's Death Benefits
     -----------------------
     Upon the death of a Participant prior to Retirement, the Company shall pay
     to the Surviving Spouse (if any) of such Participant a death benefit which
     when combined with the death benefit which he or she is entitled to receive
     under the Retirement Plan and the Supplemental Benefit Plan A shall equal
     the death benefit that would have been payable to the Surviving Spouse had
     the Retirement Plan's benefit provisions been applied as provided in
     Section 5.1 or 5.2 above, as applicable.
     
5.4  Disability Benefits
     -------------------
     In the event a Participant becomes Disabled, the Company shall pay to such
     Participant supplemental pension benefits which when combined with the
     amounts he or she is entitled to receive under the Retirement Plan and the
     Supplemental Benefit Plan A shall equal the retirement pension benefits
     which would have been payable to the Participant had the Retirement Plan's
     benefit provisions been applied as provided in Section 5.1 or 5.2 above, as
     applicable.

                              PAYMENT OF BENEFITS
                                
                                
6.1  Payment of Benefits
     -------------------
     Upon the Retirement of a Participant who is also a participant in the
     Retirement Plan, the Company shall pay to such Participant the benefit
     provided in Section 5 in the form of payment selected by the Participant
     under the Retirement Plan.  If a Participant in this Plan is not also a
     participant in the Retirement Plan, the Company shall pay to such
     Participant the benefit provided in Section 5 in the form of a monthly
     annuity payable from the commencement date as provided in Section 6.2 to
     the first of the month preceding death.  Upon the death of a Participant,
     the Company shall pay any death benefit provided in Section 5 to the
     Surviving Spouse in the same form of payment which death benefits under the
     Retirement Plan are payable to the Surviving Spouse.

     Notwithstanding the above, the Compensation Committee in its discretion may
     direct payment of the benefit for a Participant or Surviving Spouse in the
     form of a lump sum cash payment if the Compensation Committee determines
     that such payment is in the best interest of the Company.

     The amount of any such lump sum payment shall be determined by calculating
     the benefit according to the terms of the Retirement Plan as a whole life
     annuity, then calculating the present value of such benefit using the
     actuarial assumptions specified in the Retirement Plan for determining
     benefits of equivalent value, without regard to the provision for use of
     Pension Benefit Guarantee Corporation rates for calculating lump sums.

6.2  Commencement of Payment
     -----------------------
     If a Participant in this Plan is also a participant in the Retirement Plan,
     benefits for the Participant or Surviving Spouse under this Plan shall
     commence on the same date that benefits commence under the Retirement Plan.
     If a Participant in this Plan is not also a participant in the Retirement
     Plan, benefits to the Participant shall commence as of the first day of the
     month coincident with or next following the date of Retirement.  Benefits
     to a Surviving Spouse shall commence as of the first of the month following
     the Participant's death if the Participant was age 55 or older, or as of
     the first of the month following the date on which the Participant would
     have reached age 55 if the Participant was younger than age 55 at the time
     of death.

7.1  Unfunded Obligation
     -------------------
     The supplemental benefits to be paid to Participants or their Surviving
     Spouses pursuant to this Plan are unfunded obligations of the Company, and
     shall, until actual payment, continue to be an obligation against the
     general funds of the Company.  The Company is not required to segregate any
     monies from its general funds, or to create any trusts, or to make any
     special deposits with respect to these obligations.  Nothing contained
     herein shall be deemed to create a trust of any kind or create any
     fiduciary relationship.  To the extent that any person acquires a right to
     receive payments from the Company under this Plan, such right shall be no
     greater than the right of any unsecured general creditor of the Company.

7.2  Nonassignment
     -------------
     The right of a Participant or his or her Surviving Spouse to the payment of
     any amounts under the Plan may not be assigned, transferred, pledged or
     encumbered nor shall such right or other interest be subject to attachment,
     garnishment, execution or other legal process.

7.3  No Right to Continued Employment
     --------------------------------
     Nothing in the Plan shall be construed to confer upon any Participant any
     right to continued employment with the Company or a Subsidiary, nor
     interfere in any way with the right of the Company or a Subsidiary to
     terminate the employment of such Participant at any time without assigning
     any reason therefor.

7.4  Withholding Taxes
     -----------------
     Appropriate payroll taxes shall be withheld from cash payments made to
     Participants pursuant to this Plan.

7.5  Termination and Amendment
     -------------------------
     The Board of Directors of the Company reserves the power at any time to
     terminate this Plan and delegates to the Compensation Committee the power
     to otherwise amend any portion of the Plan other than this Section 7.5;
     provided, however, that no such action shall adversely affect the right of
     any Participant (or Surviving Spouse) to a benefit to which he or she has
     become entitled under the Plan. Notice of termination or material amendment
     of the Plan shall be given in writing to each Participant.
     
     If the Plan is terminated, Participants and Surviving Spouses who have
     accrued benefits under the Plan as of the date of termination will receive
     payment of such benefits at the times specified in the Plan.

7.6  ERISA Exemption
     ---------------
     This Plan is intended to qualify for exemption from Parts II, III, and IV
     of ERISA as a plan maintained primarily for the purpose of providing
     deferred compensation for a select group of management or highly
     compensated employees under Sections 201(2), 301(a)(3) and 401(a)(1) of
     ERISA.

7.7  Applicable Law
     --------------
     The Plan shall be construed and governed in accordance with the laws of the
     State of Washington.

                    THIRD AMENDMENT TO EMPLOYMENT AGREEMENT



     THIRD AMENDMENT to employment agreement by and between Advanced Technology

Fellow Shareholders:

It is my pleasure to report that 1996 was another year of significant progress 
for ATL, and that the key strategies are in place for continued success in 1997 
and into the future. Among the year's most notable accomplishments were:

 .  Record revenues of $419.2 million, record gross margins of 48.9% and record
   profitability of $1.46 per share, a 95% increase over 1995, excluding non-
   recurring items in both years;

 .  Market share gains based on the growth of our premium performance HDI(R)3000
   product family and mid-range Apogee(R) 800Plus System;

 .  Successful entry into the Japanese ultrasound market with our partner, 
   Hitachi Medical Systems;

 .  A technology transfer and distribution agreement for the Apogee system with
   the Shantou Institute of Ultrasonic Instruments, the largest ultrasound 
   manufacturer in the People's Republic of China:

 .  The industry's first and only PMAs (premarket approval) for the use of our
   HDI and HDI 3000 systems in the differentiation of indeterminate breast 
   tumors following mammography, thereby helping reduce the need to perform 
   biopsy to rule out breast cancer;

 .  U.S. Department of Defense award for development of a digital handheld
   ultrasound instrument to ATL and a consortium comprised of the University of
   Washington, Harris Semiconductor and VLSI Technology; and

 .  Selection of the HDI 3000 system for NASA's International Space Station, 
   scheduled for launch in 1999 and to remain in orbit for 10 years.

   Since its introduction, the HDI 3000 product family has met with resounding 
success and now claims a worldwide installed base approaching 3,000 systems in 
number. Designed to increase diagnostic information through advanced digital 
architecture and software programmability, the HDI 3000 system has led in 
opening new areas of ultrasound imaging such as musculoskeletal and 
intraoperative applications. Our commitment to pioneering digital ultrasound has
yielded a succession of advances and new capabilities, unmatched by any other 
system.

   During the year, the HDI 3000 system gained growing recognition for its 
outstanding image quality in cardiac patients whose physical characteristics 
make them difficult to image with ultrasound. Additionally, leading 
cardiologists have stated that the harmonic imaging capabilities of the HDI 3000

                               -----------------
 
make it the system of choice for research and development with the new 
generation of ultrasound contrast agents just entering the marketplace. This 
development promises to significantly reduce the need for nuclear medicine and 
invasive diagnostic procedures in cardiology.

   The Apogee system also enjoyed another excellent year with a strong 
performance in international markets. The feature set of this versatile system 
was expanded, particularly in cardiology, with the introduction of convex phased
array scanhead technology, a new generation of solid state scanheads that 
provide excellent resolution of cardiac anatomy.

   On February 20, 1997, we announced a fundamentally new, software-based 
ultrasound system to address the performance and cost demands of the world's 
health care markets. The HDI 1000 is the first ultrasound system to replace more
than half of its hardware components with software, bringing the benefits of 
smaller size, lower cost, flexibility, digital processing and advanced 
networking capabilities to the important mid-range markets. Our successful HDI 
broadband imaging technology is the heart of the HDI 1000 system. Just as ATL 
pioneered all-digital ultrasound technology over a decade ago, we are now 
bringing the software revolution to ultrasound. With the HDI 3000 product 
family, the Apogee 800PLUS and HDI 1000 systems, ATL offers a product range that
addresses over 80% of the worldwide ultrasound market.

   In addition to the introduction of the HDI 1000 system, we recently made two 
other announcements critical to achieving our worldwide growth objectives; 
establishment of a subsidiary in the People's Republic of China and formation of
the Handheld Systems business group. ATL China builds on the strong 
relationships we have developed with the medical community in China over the 
past 20 years and will expand our presence in this key strategic market. The new
Handheld Systems business group will focus on product and commercial market 
development of an ultrasound system small enough to be held in a clinician's 
hand or fit into the pocket of a lab coat. We believe this product will be ready
for market in approximately two years and has the potential to create entirely
new markets for the use of medical ultrasound.

   New markets made possible by advances such as a handheld ultrasound device, 
the advent of contrast agents, broadening clinical applications and expanding 
geographic opportunities are among the many reasons

                       CREATING THE FUTURE OF ULTRASOUND

Change is in the air. Six years ago, ATL introduced High Definition(TM) Imaging 
(HDI) and changed medical ultrasound forever. Capable of capturing greater 
diagnostic information than possible before with ultrasound, HDI revealed new 
dimensions of inner space, expanding our knowledge of the human body and the 
clinical realm of ultrasound. ATL's most advanced system, the HDI 3000, 
continues the legacy of opening new frontiers with its selection for NASA's 
International Space Station. And in 1997, ATL is integrating High Definition 
Imaging into a revolutionary new, software-based product, the HDI 1000 system, 
aimed at the world's most rapidly growing health care markets.

   HDI technology is based on more than a decade of pioneering broadband digital
ultrasound and advanced system software. Its evolution is leading to clinical 
applications that were once the sole domain of more expensive imaging procedures
such as computed tomography or magnetic resonance imaging. The superb resolution
of High Definition Imaging is also helping spare patients the cost and trauma of
invasive diagnostic procedures such as biopsy, exploratory surgery and cardiac 
catheterization.

   ATL's strategy is to leverage its growing technology leadership in two major 
directions - advancing performance and capabilities while reducing cost and 
size. The HDI 3000 and the HDI 1000 systems both contain more image processing 
performance at a lower cost in less space with less power requirements than 
competitive systems. ATL is also capitalizing on its technological lead to 
compress unprecedented levels of performance into a future ultrasound device 
small enough to be held in one's hand, powerful enough to save lives on the 
battlefield and affordable enough to become a routine tool in the daily practice
of medicine.

   This annual report features just a few of the emerging markets ATL is 
pioneering that highlight ultrasound's ever-expanding diagnostic role.

New Dimensions of Inner Space

Imaging the Heart -- An enduring diagnostic challenge following a heart attack 
is detecting blood flow in the network of microscopic capillaries that nourish 
the heart's muscle; vessels so minute that less than a droplet of blood passes 
through a single capillary in a year. In 1996, the HDI 3000 became the first 
system offering harmonic imaging for use with ultrasound contrast agents now 
entering the market. Harmonic imaging offers the promise of determining if blood
flow has been restored to the tiny vessels responsible  for keeping the heart 
alive after treatment for a heart attack.

   Through software upgradability, the HDI 3000 system is optimized to 
specifically detect the characteristic harmonic signature of an individual 
contrast agent as it travels through the heart's muscle. Cardiologists may one 
day be able to use ultrasound contrast agents to quantify blood flow in this 
tissue, eliminating the risk and expense of many diagnostic catheterization and
nuclear medicine procedures

                       CREATING THE FUTURE OF ULTRASOUND
 
that are standard practice today. More than 50 medical research centers around 
the world are using the HDI 3000 system to investigate new uses of contrast 
agents and evaluate their effectiveness for cardiac studies, as well as 
visualization of tumor vascularity and detection of breast, prostate and liver 
cancers.

   Power Harmonic(TM) Imaging, another proprietary ATL technology, heightens the
system's sensitivity to contrast agents, thereby aiding in the ability to 
detect minute quantities of a contrast agent, opening new possibilities in 
the diagnosis of cardiovascular disease. ATL was able to quickly implement Power
Harmonic Imaging onto the HDI 3000 system with no hardware changes due to the 
flexibility of its digital, software-driven architecture.

3D Ultrasound -- ATL has led in ultrasound imaging of the human anatomy in three
dimensions. Now 3D adds the third dimension for displaying spatial relationships
of anatomy. With the supercomputing capabilities of the HDI 3000 system 
architecture, ATL is the only ultrasound company to make commercially available 
integrated three-dimensional imaging of the human vascular system, 3D Color 
Power Angio(TM) (CPA). Research clinicians report that 3D CPA offers significant
potential in the early detection of fetal abnormalities, assessment of blood 
flow in the placenta, monitoring the viability of kidney and liver transplants 
and following the progress of tumor therapy.

   ATL is collaborating with Silicon Graphics and Vital Images, Inc. on the next
generation of 3D imaging, Digital 3DI(TM), to provide physicians with 
interactive quantifiable grayscale images and color Doppler information. The 
capability will render 3D images almost instantaneously and may be useful in a 
wide variety of clinical situations from surgical planning to assessing fetal 
health.

   Robust software architecture with the flexibility to support advances such as
3D imaging was among the principal reasons for selection of the HDI 3000 system 
as the ultrasound technology for NASA's International Space Station. Scheduled 
for launch in March 1999 and to remain in orbit for 10 years, the HDI system 
will keep pace with advancing technology by receiving software upgrades from a 
ground station via satellite. Ultrasound images of the astronauts will be 
transmitted to earth for scientists to study the effect of zero gravity on blood
flow, the heart and other internal organs. One day, ultrasound image data sets 
may be transmitted from clinics to major medical centers to aid in the rapid 
diagnosis of patients on earth.

Adding Vision to the Surgeon's Fingertips -- Innovation of scanhead technology 
and design is instrumental to the expanding use of ultrasound. A scanhead is a
wand-like sensor connected to the ultrasound system, transmitting and receiving 
soundwaves from the body. ATL's surgical scanheads, introduced over the last two
years, are providing surgeons with a view of organs never before available to 
them. Studies have

shown the use of ultrasound during liver surgery helps detect pathology that is
neither visible nor palpable, and has altered surgical decision-making in up to 
half of the cases.

   ATL engineers work closely with surgeons to develop ergonomic, lightweight 
designs that go anywhere the surgeon's hands go, providing vital information and
helping improve patient care. This same design expertise is being applied to our
laparoscopic probe, to bring HDI performance to this rapidly growing field of 
minimally-invasive surgery. Laparascopic surgeries and biopsies of abdominal and
gynecologic organs offer patients quicker recovery, less pain and greater 
safety.

Virtual Ultrasound Technology
   The HDI 1000 system is an entirely new class of ultrasound, integrating 
all-digital, broadband High Definition Imaging with revolutionary system 
software architecture to create excellent performance at a lower cost.

   Employing our advances in broadband digital electronics with our expertise in
ultrasound software, ATL engineers invented a sophisticated new operating 
environment, Multitasking Software Management. MSM(TM) technology replaces more 
than half the ultrasound system's hardware components with software. Through the
use of "object-oriented software," each software task in the MSM environments is
independent and self contained, making upgrades quick, easy to perform and 
cost-effective. This breakthrough and the resulting reduction in size, weight 
and cost led to ATL's new HDI 1000 ultrasound system, bringing a new level of 
performance to cost-conscious health care environments.

   This is the first time an ultrasound company has migrated its premium 
technology into the mid-range market. Similar user interface, analysis software 
and scanhead compatibility with the HDI 3000 system allows clinicians to 
leverage their investment in training and accessories. Additionally, the HDI 
1000 system integrates advanced communication capabilities for printing to 
standard desktop printers, easy remote consultation or even software upgrades 
and system diagnostics via the Internet in the future.

   The market for mid-range and high performance systems accounts for over 60% 
of the estimated $2.3 billion worldwide ultrasound market and is growing rapidly
as economics strengthen in many parts of the world. In the United States, as 
well, restructuring to favor managed care systems and health care networks 
demands new levels of price performance and interconnectivity. The replacement
of hardware functionality with the virtual components of software enables the 
HDI 1000 system to offer unprecedented performance to this market, and 
unparalleled flexibility to harness the benefits of rapidly advancing 
microprocessor and ultrasound technology.

   ATL continues to change the rules of ultrasound, challenging its technical 
boundaries and expanding its diagnostic domain. New applications, software 
upgradability. New levels of price performance and broadening clinical utility. 
ATL is setting the standard for ultrasound performance today and blazing the 
path to its future.

                   MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

    ATL develops, manufactures, markets and services diagnostic medical
ultrasound systems and related supplies and accessories worldwide. ATL sells
products and services to hospitals, clinics and physicians for use in radiology,
cardiology, women's health care, vascular, musculoskeletal and intraoperative
applications. Sales are made through a direct sales force in the U.S. and
through direct sales or third party distributors in international markets.

    The ultrasound industry is highly competitive and market demand is
influenced by a variety of factors. These include the introduction of new
technologies which may offer improved clinical capabilities and create demand
for new products, the relative cost-effectiveness and clinical utility of
competing diagnostic technologies, the structure of health care delivery
organizations, government policies with respect to reimbursement and containment
of medical costs, and the economies and demographics in countries the Company
markets its products. Although ultrasound systems are typically sold based on
image quality, Doppler sensitivity, product reliability, upgradeability,
clinical versatility and ease of use, price competition is also an important
factor. Fundamental restructuring in the U.S. health care system resulted in a
contraction of the traditional U.S. ultrasound market from 1993 to 1995 and a
growing focus on containment of medical costs, adding to the existing
competitive pressures in the ultrasound industry.

    ATL markets and services products worldwide. International revenues
accounted for 49% of 1996 revenues. A significant portion of these revenues as
well as the operating expenses of the Company's direct sales and service
operations were denominated in foreign currencies. In addition, some of ATL's
competitors are foreign companies whose production costs are incurred in foreign
currencies. As a result, fluctuations in foreign currency exchange rates may
impact the Company's competitive position and financial results. The Company
hedges foreign exchange exposure related to its intercompany accounts payable
and receivable balances which are denominated in foreign currencies through the
use of forward exchange contracts. The Company does not otherwise hedge foreign
currency exposures.

    ATL reported a net loss in 1996 of $0.8 million or $0.06 per share.
Excluding a one-time charge for a litigation claim and the related tax benefit,
ATL earned net income of $21.8 million or $1.46 per share in 1996. In 1995, ATL
reported net income of $12.0 million or $0.85 per share on a fully diluted
basis. Excluding three non-recurring items totaling a net gain of $1.4 million
or $0.10 per share, ATL's 1995 net income would have been $10.6 million or $0.75
per share on a fully diluted basis. The improvement in operating results in 1996
is based on the success of ATL's digital, scanhead and software ultrasound
technologies, the development of new clinical applications and the formation of
strategic partnerships, as well as programs to improve expense structures.

product lines, continuing the shift which began in 1995. Sales of the HDI 3000
and Apogee 800PLUS products contributed more than 60% of 1996 product revenues,
up from approximately 50% in 1995. The phase out of older products from the
product line, such as the Ultramark(R) 4 system, partially offset the revenue
growth achieved with the newer products in 1996. The HDI 3000cv system,
introduced in June 1995 with complete cardiology capabilities, drove revenue
growth in the cardiology market segment in 1996. ATL received premarket approval
(PMA) from the U.S. Food and Drug Administration (FDA) for the use of its HDI
technology in the differentiation of indeterminate solid breast tumors as an
adjunct to mammography and physical examination thereby helping reduce the need
to perform biopsies to rule out cancer. The FDA approved the HDI system for this
application in April 1996 and the HDI 3000 system in December 1996. Service
revenues increased $6.1 million from 1995 on the continued growth in the
worldwide installed base of ATL's products.

    International revenues grew 9% to $206.8 million during 1996, primarily due
to growth in the Asia Pacific region. In the fourth quarter of 1996, ATL
announced a technology transfer agreement with Shantou Institute of Ultrasonic
Instruments (SIUI), the largest manufacturer of ultrasound systems in the
People's Republic of China. ATL will transfer the Apogee 800PLUS ultrasound
system manufacturing technology and exclusive distribution rights to SIUI in the
PRC. ATL will continue to manufacture and distribute the Apogee 800PLUS system
worldwide outside of China. In addition, ATL entered the Japanese market in
1996, as Hitachi Medical Corporation (Hitachi) began distributing ATL's HDI 3000
system in Japan under a distribution agreement signed in December 1995.
International revenues totaled 49% and 47% of total revenues in 1996 and 1995,
respectively. In the U.S., constrained market conditions continued in 1996 where
revenues grew to $212.4 million, up 1% from 1995.

          MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
                           AND RESULTS OF OPERATIONS
 
    1995 revenues increased 9% or $33.3 million over 1994 reflecting favorable
changes in product mix toward the HDI 3000 and Apogee 800PLUS products.
Synergies achieved from the integration of the Interspec product lines into
ATL's distribution channels, particularly in international markets, resulted in
higher sales of the mid-range Apogee systems.  Service revenues increased $5.4
million from 1994 due to an increasing installed base of ATL's products and
higher volume of service maintenance contracts.

    Gross profit increased 11% in 1996 to $205.0 million, compared with $184.5
million in 1995.  Gross margin in 1996 was 48.9% compared with 46.2% in 1995.
The improvement in gross margin is due to the favorable shift in product mix to
the Company's higher margin products, the consolidation of ATL's manufacturing
operations, efficiencies achieved in international and U.S. service operations
and continued progress on cost reduction programs.  The improvement in gross
margin also reflects the expansion of the HDI 3000 product family and its
applications through software programmability.  Gross profit rose on higher unit
volumes of the HDI and Apogee products, but the growth was partially offset by
lower volume of older product lines and the impact of competitive pressures on
the mid-range product prices.  1995 gross margin improved to 46.2% compared with
44.7% in 1994.  The higher gross profit reflects the initial shift in product
mix toward the higher priced and higher margin products, as well as product cost
reduction programs and improved service operating efficiencies.

    Selling, general and administrative (SG&A) expenses increased by $3.0
million in 1996, but declined as a percent of revenues to 29.3% compared with
30.0% in 1995 and 31.6% in 1994. The increase in SG&A is attributed primarily to
marketing programs related to the promotion of the HDI system for
differentiation of solid breast tumors and investments in the Company's business
information systems. In 1995, SG&A expenses increased $4.4 million from 1994 as
a result of expansion of sales and marketing activities in the image management
market and in selected international markets.

    ATL continued its commitment to advancing broadband digital ultrasound
technology by investing $54.0 million in research and development (R&D) expenses
in 1996.  As a percent of revenues, 1996 R&D expenses were 12.9% compared with
12.6% in 1995 and 15.4% in 1994.  On February 20, 1997, ATL announced the
introduction of the HDI 1000 system, a fundamentally new software based
architecture which uses ATL's all-digital, broadband High Definition Imaging
technology and new Multi-tasking Software Management (MSM(TM)).  By replacing
over half the hardware components with software, the HDI 1000 system offers
advanced performance at a lower cost in a mid-range product. Shipments of the
HDI 1000 system are expected to begin in the second quarter of 1997. Some of the
technology used in the HDI 1000 system was developed by ATL as part of an R&D
joint venture project with Hitachi which began in the fourth quarter of 1995. In
1995, ATL received $10.0 million from Hitachi and reported a $6.2 million gain.
Under the terms of the joint venture, ATL received $2.3 million in 1996 and $1.0
million in 1995 from Hitachi based upon the achievement of defined development
milestones. The R&D joint venture is expected to continue through 1997. The
technology resulting from this joint development will be available to both ATL
and Hitachi for new product offerings and product features. ATL will receive
royalty payments in the future based upon Hitachi's revenues from the jointly
developed technology.

    In 1996, ATL, the University of Washington, Harris Semiconductor and VLSI
Technology entered into a consortium to develop a handheld ultrasound device to
be used on battlefields and in other emergency situations.  The U.S. Department
of Defense selected the project for matched funding and will contribute
approximately half of the estimated project costs with the remaining funding
coming from the project consortium.  In 1996, ATL received approximately $1.1
million from the Department of Defense on this project which is reported in
research and development expense.

    1995 R&D expenses decreased $6.2 million from 1994 to $50.3 million.  The
reduction in R&D expense followed the 1994 new product introductions, including
the HDI 3000 system and three new broadband scanheads.

    Other expense, net, was $1.5 million in 1996.  This includes $0.7 million of
Washington State Business and Occupation (B&O) tax expense and $0.3 million
foreign exchange losses.  B&O tax is imposed on gross receipts for products
manufactured in the State of Washington and is levied in lieu of a state income
tax. In 1995, ATL reported a non-recurring benefit as a result of a B&O tax
audit, of which $1.0 million is included in other expense, net.

RESTRUCTURING AND RELOCATION

    During 1995, the Company consolidated the Interspec operations located in
Ambler, Pennsylvania with the Company's headquarters in Bothell, Washington.
The consolidation resulted in the relocation of Ambler manufacturing,
administrative and R&D functions to Bothell.

    The Company intends to hold the Ambler land and building and is marketing
the facility for lease. The Company has evaluated the carrying value of the
property by comparing the estimated future cash flow expected to be generated
from the property to its current net book value. The actual cash flows generated
from the use and disposal of the property could differ materially from the
amounts assumed in performing the evaluation of the carrying value and could
result in an impairment being recognized in the future.

ACCRUAL FOR LITIGATION CLAIM

    ATL accrued a non-recurring provision for a patent litigation claim of $29.6
million in the second quarter of 1996 in addition to $5.0 million which had been
accrued in 1994.  The underlying lawsuit was filed by SRI International (SRI) on
July 15, 1991 in the U.S. District Court for the Northern District of California
and concerns a patent on an electrical circuit allegedly used in three of ATL's
discontinued products.  The patent expired in the 1994 and the circuit in
dispute has never been used in any of ATL's current product lines.  The court
granted a motion by SRI requesting partial summary judgment in November 1992 and
the U.S. Court of Appeals for the Federal Circuit affirmed the summary judgment
in December 1994.  In May 1996, the District Court awarded damages to SRI of
$27.9 million plus interest and legal fees.  The Company has appealed the amount
of damages awarded and has posted a supersedeas bond secured by a letter of
credit collateralized by cash and short-term investments.  ATL accrued interest
expense of $1.2 million on the full award in 1996 and will continue accruing
interest during the appeal process.

    Interest income increased in 1996, reflecting higher cash balances available
for investment compared with 1995. The higher interest expense in 1996 reflects
post-judgment interest accrued on the damages awarded for the patent litigation
claim previously discussed. Interest expense increased in 1995 compared with
1994 due to a long-term variable interest mortgage which was entered into in
December 1994 to finance the purchase of land and a building adjacent to ATL's
corporate headquarters in Bothell, Washington.

    The company finances its operations primarily with internal resources,
including cash and short-term investments. The Company held $63.3 million in
cash and short-term investments at December 31, 1996. Short-term borrowings
represent working capital lines of credit maintained at several of the Company's
foreign subsidiaries to facilitate intercompany cash flow.

    As shown in the statement of cash flows, ATL generated cash from operations
of $45.2 million in 1996 compared with $13.5 million in 1995. The improvement in
cash flows from operations primarily reflects the growth in 1996 net income,
excluding the provision for litigation claim. Cash flows from investing
activities included $14.9

million used for property, plant and equipment purchases. During 1996, exercise
of employee stock options generated cash flow of $8.6 million.

    Long-term debt at December 31, 1996 was $12.9 million. The Company converted
the final $1.2 million of its 11% subordinated convertible debentures into
71,577 shares of the Company's common stock in February 1996. Interest rates on
long-term debt outstanding at December 31, 1996 averaged approximately 6.3%.

    The Company repurchased 289,000 shares of its own common stock in the open
market for $8.5 million in 1996 under a share repurchase program intended to
service ATL's benefit programs.  In May 1996, the Board of Directors authorized
the Company to purchase up to 1,000,000 shares under this program, subject to
certain criteria.

    The Company had an accrued liability of $35.6 million at December 31, 1996
for the patent litigation claim discussed previously. In June 1996, the Company
posted a supersedeas bond secured by a letter of credit collateralized by cash
and short-term investments. The Company will utilize its cash and short-term
investments to pay the final assessment of damages from the patent litigation
claim after the appeal process is completed.

    The Company has occasionally utilized its cash resources to make
acquisitions of technology or small technology-related businesses. The Company
may undertake further acquisitions of technology in the future.

    In addition to its cash balances, the Company has available unsecured credit
facilities of $25 million, including a committed line of credit of $15 million.
Barring any unforeseen circumstances, events or unanticipated expenses,
management expects existing cash and available credit lines and cash generated
from operations should be sufficient to meet the Company's operating
requirements for 1997.

OTHER BUSINESS FACTORS

    Like many companies in high technology businesses, the Company can from time
to time experience difficulty with the availability of technology employed in
its products. Such difficulties can lead to increases in component costs, long
order lead times or delays in the Company's manufacture of products.
Manufacturing efforts can also be impeded by third party assertions of patent
infringement by the Company's products, such as the litigation claim previously
discussed. There can be no assurance the Company will not be subject to claims
of patent infringement by other parties or that such claims will not require the
Company to pay substantial damages or delete certain features from its products
or both.

    The Company is subject to certain rules, regulations and inspections of the
FDA and other regulatory agencies regarding the design, manufacture, marketing
and performance of its products. The Company's ability to manufacture products
and obtain timely FDA export and new product approvals is dependent upon the
results of FDA inspections and reviews. The Company can incur substantial
expense in responding to process improvements and modification of products
previously sold to customers which stem from comments and new requirements of
the FDA.

    The Company's regulatory compliance programs have been expanded to comply
with international quality system standards known as ISO 9000 standards. ATL has
maintained registration under the ISO 9000 quality systems standards for its
operations. In 1995, ATL's HDI 3000 system qualified to display the European
Community (CE) Mark. By 1998, all medical device companies marketing products in
the European Community will be required to meet these standards.

FORWARD LOOKING INFORMATION

    Under the safe harbor provisions of the Private Securities Litigation Reform
Act of 1995, the Company provides the following information.

    In 1997, the Company will continue to pursue its long-term goal of achieving
a return on shareholders' equity of 15%, compared with approximately 10% in
1996, excluding non-recurring items. The Company expects total revenues to
increase in 1997, but the increase is expected to be moderated during the first
half of the year as customer evaluate new product offerings, by the drop off of
older products, and the divestiture of the Company's image management business.
The declining unit volume of older products is expected to result in an improved
product mix for the Company, which, in conjunction with continuing cost
reduction programs, should result in an improved gross margin for the year. The
combined effects of these results, despite an increase in operating expenses of
$4.0 to $6.0 million during the first half of the year to successfully introduce
new product offerings, are expected to lead to higher net income and earnings
per share for the Company in the full year 1997 compared with the 1996 results,
excluding the provision for litigation claim accrued in 1996. However, it is
expected that earnings will be lower in the first two quarters in comparison to
the prior year.

    The above statements and certain other statements in this report are forward
looking statements that involve a number of risks and uncertainties, and should
be read in conjunction with the Company's SEC filing and news releases.  Among
the ongoing factors that could cause actual results to differ materially from
the above are the following considerations.  The U.S. ultrasound market remains
sluggish and may cause revenue growth to fall short of expectations.  Worldwide
competition in the ultrasound market has intensified over the past year, and
most of the Company's competitors have introduced new ultrasound products within
the past two years.  The time required for customers to evaluate the many new
products on the market may lengthen the sales cycle for ultrasound purchases.
These factors may adversely impact the Company's sales volume or selling prices
or both.  Unan-

ticipated events, such as delays in the Company's product development and cost
reduction programs, the unavailability of components critical to the Company's
products due to natural disasters, changes in vendor businesses or otherwise,
the strengthening of the U.S. dollar, delays in receiving necessary regulatory
approvals, unanticipated liabilities, expenses, claims, litigation or other
unforeseen events could adversely impact the Company's financial results for
1997.


IMPACT OF NEW ACCOUNTING STANDARDS

In 1996, the Financial Accounting Standards Board issued FAS 125, "Accounting
for Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities," which is effective for transfers and servicing of financial assets
occurring after December 31, 1996. The adoption of FAS 125 is not expected to
have a material effect on ATL's consolidated financial statements.

SUBSEQUENT EVENT

On January 24, 1997, the Company signed a letter of intent to sell its Nova
Microsonics division (NMS) to the Eastman Kodak Company.  NMS's operations focus
on digital image management.  NMS is headquartered in Allendale, New Jersey and
its revenues in 1996 were less than 5% of the Company's total revenues.  The
agreement is subject to certain legal, regulatory and financial review.
Completion of the sales transaction is expected within 90 days of signing the
letter of intent and is not expected to have a material financial impact.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


Basis of Presentation

    The consolidated financial statements include the accounts of Advanced
Technology Laboratories, Inc. (ATL) which include its subsidiaries and is
referred to as the "Company."  All significant intercompany accounts and
transactions have been eliminated in consolidation.

Operations

    The Company develops, manufactures, markets and services diagnostic medical
ultrasound systems and related accessories and supplies worldwide. The Company
sells its products to hospitals, clinics and physicians for use in radiology,
cardiology, women's health care, vascular, musculoskeletal and intraoperative
applications.

    ATL had two core product lines in 1996, the HDI 3000 and the Apogee 800PLUS
systems.  Sales of the HDI 3000 and Apogee 800PLUS products contributed more
than 60% of 1996 product revenues, up from approximately 50% in 1995.

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 date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Concentration of Credit Risk

    Financial instruments which potentially subject the Company to credit risk
consist primarily of short-term investments, foreign currency exchange contracts
and trade receivables.  The Company's investment portfolio is diversified and
consists primarily of investment grade securities that approximate fair market
value.  The Company concentrates its foreign currency exchange contracts
primarily with one major U.S. financial institution.


    Concentrations of credit risk with respect to receivables are limited due to
the Company's large, diverse customer base, generally short payment terms and
the dispersion of customers across geographic areas. The Company generally
performs credit evaluations of its customers' financial condition and requires
collateral, such as letters of credit, in certain circumstances. The Company has
sales in certain Latin American countries where extended credit terms are
offered. The long-term installment receivables created from these sales are
subject to greater risk of loss than the remainder of the Company's trade
receivables. The Company believes it has adequately provided for these risks in
the allowance for doubtful accounts.

Financial Instruments

    The Company enters into foreign currency exchange contracts to hedge against
exposure to foreign currency fluctuations associated with intercompany
receivables and payables denominated in foreign currencies.  Foreign exchange
contracts generally have maturities of less than one year.  Gains and losses
resulting from these instruments are recognized in the same period as the
underlying hedged transactions.  At December 31, 1996 and 1995, the Company had
foreign currency exchange contracts to purchase totaling $15,632 and $3,702 and
to sell totaling $28,260 and $32,993, respectively.  The Company does not use
foreign currency exchange contracts or other derivative financial instruments
for speculative or trading purposes.

    The Company has other financial instruments consisting of cash and short-
term investments, trade receivables, long-term installment receivables, accounts
payable, short-term borrowings and long-term debt. The fair value of the
Company's financial instruments based on current market indicators or quotes
from brokers approximates their carrying amount.

Foreign Currency

    Revenues, costs and expenses of the Company's international operations
denominated in foreign currencies are translated to U.S. dollars at average
rates of exchange prevailing during the year.  Assets and liabilities are
translated at the exchange rate on the balance sheet date.  Translation
adjustments resulting from this process are accumulated and reported in
shareholders' equity.

    Realized and unrealized gains and losses on foreign currency transactions
and forward exchange contracts are included in other (income) expense, net.

Cash and short-term investments

    Short-term investments are stated at cost.  For purposes of the statement of
cash flows, cash equivalents are defined as investments with maturities of three
months or less at the date of purchase.

Investment Securities

    Management determines the appropriate classification of its investments in
debt or equity securities as held-to-maturity, trading or available-for-sale
securities at the time of purchase. At December 31, 1995, the Company held one
marketable debt security classified as a held-to-maturity security stated at
cost, which approximated fair value.

Inventories

    Inventories are valued at the lower of cost, determined by the first-in,
first-out method, or market. The Company maintains a uniform policy for its
worldwide operations to provide adequate reserves for inventory obsolescence.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                                          
Property, Plant and Equipment

    The costs of significant additions and improvements to property, plant and
equipment are capitalized.  Maintenance and repair costs are expensed as
incurred.  Buildings, machinery,  equipment, computers and purchased software
are depreciated primarily using the straight-line method over the following
estimated useful lives:

- --------------------------------------------------
Buildings                              40 years

Machinery and equipment                3-10 years

Computers and purchased software       3-5 years
- --------------------------------------------------

    Leasehold improvements are amortized over the shorter of their useful lives
or the term of the lease. For long-lived assets, including property, plant and
equipment, the Company evaluates the carrying value of the assets by comparing
the estimated future cash flows generated from the use of the asset and its
eventual disposition with the assets' reported net book value. The carrying
value of assets are evaluated for impairment when events or changes in
circumstances occur which may indicate the carrying amount of the asset may not
be recoverable.

Revenue

    Revenue is generally recognized upon shipment of products and delivery of
services to customers.

    Deferred revenue consists of deposits received from customers and
unrecognized service contract revenue. Service contracts are issued for annual
and multi-year periods. The revenue derived from these contracts is initially
deferred and subsequently recognized on the straight-line method over the lives
of the contracts.

Sales-type Leases

    The Company leases its ultrasound imaging systems to customers under sales-
type leases with terms ranging from two to five years. The Company currently
sells its lease contract receivables to outside parties on a regular basis,
generally without recourse. Lease contract receivables which have not been sold
as of the balance sheet date are included in receivables, net.

Product Warranty

    At the time of shipment, the Company provides for the estimated cost to
repair or replace products sold under warranties. Such warranties generally
cover a 12-month period.

Stock-based compensation

    The Company applies APB Opinion No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations in measuring compensation costs for its
stock option plans. The Company discloses proforma net income (loss) and net
income (loss) per share as if compensation cost been determined consistent with
Statement of Financial Accounting Standard (FAS) No. 123, "Accounting for Stock-
Based Compensation."

Per Share Data

    Primary net income (loss) per common share and equivalent is calculated
based on the weighted average number of common shares and dilutive common share
equivalents outstanding. Common share equivalents include unexercised employee
stock options. For the primary per share data, the common share equivalents are
calculated under the treasury stock method using the average market price of
common shares during the period. For fully diluted per share data, the common
share equivalents are calculated under the treasury stock method using the
higher of the average market price of common shares during the period or the
market price at the end of the period.

    The subordinated convertible debentures are antidilutive and are not
included in the computation of per share data for any period.

Reclassifications

    Certain amounts reported in previous years have been reclassified to conform
to the 1996 presentation.

2.  ACQUISITION OF INTERSPEC, INC.

    On May 17, 1994, the Company completed its acquisition of Interspec, Inc., a
manufacturer of diagnostic medical ultrasound imaging systems and related
supplies and accessories.  To effect the merger, the Company issued
approximately 2,593,000 shares of common stock for all of the outstanding common
stock of Interspec, based on an exchange ratio of 0.413 share of the Company's
stock for each share of Interspec stock (Exchange Ratio).  The merger was
accounted for as a pooling of interests business combination.  Therefore, the
Company's consolidated financial statements and information reported for periods
prior to the merger have been restated to include Interspec as if the companies
had been combined for all periods presented.

    Combined and separate results of operations of ATL and Interspec prior to
the acquisition follow. Intercompany revenues and cost of sales are eliminated
in the combined results.

</TABLE>

    To conform Interspec's November 30 fiscal year end to the Company's December
31 year-end, the results of Interspec's operations for the one-month period
ended March 31, 1994 have been excluded from the Consolidated Statements of
Operations and Cash Flows and accounted for as an adjustment to retained
earnings. Therefore, the Consolidated Statements of Operations and Cash Flows
include 12 months of Interspec's operations for all years presented. For the one
month ended March 31, 1994, Interspec had a net loss of $4,180.

    In 1994, the Company reported a non-recurring charge of $5,391 for certain
costs associated with the merger.

3.  RESTRUCTURING AND RELOCATION

    In 1995, the Company consolidated the Interspec operations located in
Ambler, Pennsylvania with the Company's corporate headquarters in Bothell,
Washington. The consolidation resulted in the relocation of Ambler
manufacturing, administrative and R&D functions to Bothell.

    The Company intends to hold the Ambler land and building and is marketing
the facility for lease.  The Company has evaluated the carrying value of the
property by comparing the estimated future cash flows expected to be generated
from the property to its current net book value in accordance with FAS 121. The
actual cash flows to be generated from the use and disposal of the property
could differ materially from the amounts assumed in performing the evaluation of
the carry value and could result in an impairment being recognized in the
future.

10.   ACCRUAL FOR LITIGATION CLAIM

    The Company accrued a provision for a patent litigation claim of $29,557 in
the second quarter of 1996 in addition to $5,000 previously accrued in 1994. The
underlying lawsuit was filed by SRI International (SRI) on July 15, 1991 in the
U.S. District Court for the Northern District of California and concerns a
patent on an electrical circuit allegedly used in three of ATL's discontinued
products. The patent expired in 1994 and the circuit in dispute has never been
used in any of ATL's current product lines. The court granted a motion by SRI
requesting partial summary judgment on liability in November 1992 and the U.S.
Court of Appeals for the Federal Circuit affirmed the summary judgment in
December 1994. In May 1996, the District Court awarded damages to SRI of $27,948
plus interest and legal fees. The Company has appealed the amount of damages
awarded and has posted a supersedeas bond secured by a letter of credit
collateralized by cash and short-term. The Company accrued interest expense of
$1,168 on the full award in 1996 and will continue accruing interest during the
appeal process.

13.  EMPLOYEE BENEFIT PLANS

    Substantially all employees of the Company's U.S. operations are covered
under a noncontributory, defined benefit pension plan (Retirement Plan). The
benefits are based on each employee's years of service and highest consecutive
five year average compensation. The Company also maintains supplemental defined
benefit pension plans (Supplemental Plans) providing benefits to employees which
may not be paid from the Retirement Plan due to tax limitations plus special
benefits to certain employees. The Company makes annual contributions to the
Retirement Plan sufficient to comply with the requirements of the Employee
Retirement Income Security Act of 1974. The Supplemental Plans are unfunded.
Retirement Plan assets include primarily marketable equity and fixed income
securities.

    At December 31, 1996 and 1995, accumulated benefit obligation includes
vested benefits of $13,635 and $11,802 for the Retirement Plan and $2,926 and
$2,767 for the Supplemental Plans, respectively.

    The Company has reported an additional minimum liability of $632 and $1,342
at December 31, 1996 and 1995, respectively, representing the excess of the
accumulated benefit obligation over the fair value of plan assets and accrued
pension costs. A corresponding amount is recognized as an intangible asset to
the extent of unrecognized prior service costs.

    The projected benefit obligations are based on employee census information
as of the beginning of each year. Employees of Interspec with one year of
service became participants in the pension plan on May 17, 1994, the date of the
merger.

    The weighted average discount rate used in determining the end of year
actuarial present value of the projected benefit obligation was 7.5% for 1996,
7.25% for 1995 and 8.5% for 1994. The assumed annual rate of increase in future
compensation levels was 7.5% for the first five years of service and 5%
thereafter for 1996 and 1995; 9% for the first five years of service and 5.75%
thereafter for 1994. The expected long-term rate of return on plan assets was
10% for 1996 and 9% in both 1995 and 1994.

    A 401(k) retirement savings plan is maintained for all U.S. employees.  The
Company's contributions to this plan were $1,376, $1,317 and $1,025 in 1996,
1995 and 1994, respectively.

    The Company has a profit sharing plan which provides for employee incentive
awards when pre-tax return on sales exceeds 7%. No awards have been made under
this plan.

14.  SHAREHOLDERS' EQUITY

    At December 31, 1996, the Company had the following stock compensation
plans: the 1992 Option, Stock Appreciation Right, Restricted Stock, Stock Grant
and Performance Unit Plan, the 1992 Nonofficer Employee Stock Option Plan, the
1986 Management Incentive Plan (collectively the Employee Stock Plans); and the
Nonemployee Director Stock Option Plan. Had compensation cost for the Company's
stock-based compensation plans been determined consistent with FAS 123, the
Company's net income and earnings per share would have been reduced to the pro
forma amounts indicated below:

    Under the Employee Stock Plans, 3,120,000 shares of common stock are
authorized primarily for issuance upon exercise of stock options at prices equal
to the fair market value of the Company's common shares at the date of grant,
for restricted shares at par value, and for unrestricted shares at par value. At
December 31, 1996, 217,900 shares were available for grants under the Employee
Stock Plans. Stock options are generally exercisable at 25% each year over a
four year vesting period and generally have a term of 10 years from date of
grant.

    Under the Nonemployee Director Stock Option Plan, 105,000 shares of common
stock are authorized for the issuance of stock options at prices equal to the
fair market value of the Company's common shares at the date of grant. At
December 31, 1996, 39,000 shares are available for grants under this plan.

    Under the 1986 Option, Restricted Stock, Stock Appreciation Right and
Performance Unit Plan, there were approximately 260,000 stock options
outstanding at December 31, 1996.    Use of this Plan for grants of stock, stock
options and other awards terminated in 1992.

    The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in 1996 and 1995, respectively: expected volatility
of 34% and 26%; risk-free interest rates of 6.6% and 6.7%; expected lives of
4.25 years in 1996 and 1995; and zero dividend yield in 1996 and 1995.

    Deferred tax assets and liabilities are determined based on the difference
between the financial statements and tax bases of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to be recovered or settled.  The tax effects of temporary differences and
carryforwards which give rise to significant portions of the deferred tax assets
and deferred tax liabilities at December 31 are presented below.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
    At December 31, 1996, the Company had net operating loss carryforwards for
statutory purposes of approximately $2,100, which begin to expire after 2000 or
have no expiration date.  The Company also has U.S. research and experimentation
credit carryforwards of approximately $7,700 with expiration dates from 1997
through 2011.  Utilization of carryforwards from acquired subsidiaries may be
limited due to change in ownership rules of the Internal Revenue Code.

    Provision has not been made for U.S. or additional foreign taxes on the
undistributed earnings of the Company's foreign subsidiaries which total
approximately $7,900.  These earnings, which are anticipated to be reinvested,
could become subject to additional tax if they were remitted as dividends, lent
to the Company, or if the Company should sell its stock in these subsidiaries.

16. RESEARCH AND DEVELOPMENT ARRANGEMENTS

    In December 1995, the Company entered into a research and development joint
venture with Hitachi Medical Corporation (Hitachi).  The Company received
proceeds of $10,000 and reported a $6,220 gain.  The gain is reported in other
(income) expense, net, in 1995.  Under the terms of the joint venture, the
Company and Hitachi will develop advanced ultrasound technology with funding
provided by Hitachi based upon the achievement of certain development
milestones.  The technology resulting from this joint development will be
available to both ATL and Hitachi for new product offerings and product
features.  ATL will receive royalty payments in the future based upon Hitachi's
revenues from jointly developed technology.  ATL received funding from Hitachi
of $2,300 in 1996 and $1,000 in 1995 which is reported in research and
development expenses.

    In February 1996, the Company entered into an agreement to develop a
handheld ultrasound device to be used on battlefields and in other emergency
situations. The U.S. Department of Defense selected the project for matched
funding, contributing approximately half of the estimated costs with the
remaining funding coming from the project consortium which includes the Company,
the University of Washington, Harris Semiconductor and VLSI Technology. In 1996,
ATL received funding from the Department of Defense for eligible expenses of
$1,100, which is reported in research and development expenses.

17.  OTHER (INCOME) EXPENSE, NET

    Other (income) expense, net, includes foreign exchange gains and losses
consisting of realized gains and losses on cash transactions involving various
foreign currencies, unrealized gains and losses resulting from exchange rate
fluctuations primarily affecting intercompany accounts and gains and losses on
forward exchange contracts.  Net losses from foreign currency transactions were
$329, $22 and $144 in 1996, 1995 and 1994, respectively.

    Other (income) expense, net, also includes Washington State Business and
Occupation (B&O) taxes of $652,  $(606) and $744 in 1996, 1995 and 1994,
respectively.  This tax is a gross receipts tax imposed on products manufactured
in the State of Washington and is levied in lieu of a state income tax. The
Company reported a benefit related to a B&O tax audit which was concluded in
1995, of which $1,000 is classified as other (income) expense, net.

    Other (income) expense, net, in 1995 includes a $6,220 gain from the Hitachi
R&D joint venture, as discussed in Note 16, Research and Development
Arrangements.

18.  COMMITMENTS AND CONTINGENCIES

Leases

    The Company was obligated at December 31, 1996 under long-term operating
leases for various types of property and equipment, with minimum aggregate
rentals totaling $17,308 as follows: $5,865 in 1997, $4,482 in 1998, $2,855 in
1999, $2,121 in 2000, $1,726 in 2001 and $259 in later years.

    Many of the Company's leases contain renewal options and clauses for
escalations of rent and payment of real estate taxes, maintenance, insurance and
certain other operating expenses of the properties. Certain leases are expected
to be renewed or replaced at expiration. Total rental expense under operating
leases was $ 8,078, $6,940 and $5,276 in 1996, 1995 and 1994, respectively.

Legal Contingencies

    In addition to the legal claim discussed in Note 10, Accrual for Litigation
Claim, the Company is involved in various legal actions and claims arising in
the ordinary course of business.  The Company believes the ultimate resolution
of these matters individually and in the aggregate will not have a material
adverse effect on the Company's financial condition or results of operations.

Other

    Like many companies in high technology businesses, the Company can from time
to time experience difficulty with the availability of components employed in
its products. Such difficulties can lead to long order lead time or delays in
the Company's manufacture of products.

    The Company is subject to certain rules and regulations of the U.S. Food and
Drug Administration (FDA) and other regulatory agencies regarding the design,
documentation, manufacture, marketing and reporting of the performance of its
products.   The Company's ability to obtain timely FDA export and new product
approvals is dependent upon the results of  FDA inspections and reviews.  The
Company can also incur substantial expense in responding to process improvements
and modification of products previously sold to customers which stem from
comments and new requirements of the FDA.

    Primary earnings per share are substantially equal to fully diluted earnings
per share in all periods presented with the exception of the fourth quarter in
1995 and the full year ended December 31, 1995 when primary earnings per share
were $0.87 and $0.88, respectively.

    Quarterly per share data shown do not add to the total in 1996 and 1995 due
to changes in the number of weighted average shares outstanding during the year.

    The 1996 results include a non-recurring expense of $29,557 for a provision
for litigation claim and a $(6,900) related income tax benefit in the second
quarter. The 1995 results include the following non-recurring items:
restructuring and relocation expenses of $2,500 in the first quarter, $335 in
the second quarter, $1,838 in the third quarter and $1,262 in the fourth
quarter; a benefit for a Washington State B&O tax refund of $(1,300) in the
first quarter; and a $(6,020) after tax gain from Hitachi's investment in an R&D
joint venture in the fourth quarter.

    Excluding the impact of the non-recurring items listed above, net income and
