ITEM 1. BUSINESS
 
STRUCTURE OF THE COMPANY
 
  ATL Ultrasound, 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 14 international
affiliates and through approximately 60 local distributors worldwide.
 
COMPANY HISTORY
 
  ATL was founded in 1969 when it was incorporated as Advanced Technology
Laboratories, Inc. In 1980 the Company was acquired by Squibb Corporation
("Squibb"). 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.
 
  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 1997 the Company changed its name to ATL
Ultrasound, Inc. to more clearly designate the focus of the Company on medical
ultrasound. ATL conducts a substantial portion of its business through its
domestic operating subsidiary, now known as Advanced Technology Laboratories,
Inc.
 
  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 U.S. government's
Advanced Research Project Agency 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 is
expected to culminate in the third quarter of 1998 with the delivery of
prototype handheld ultrasound systems to the U.S. Navy, which is overseeing
the program. 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 had formed a business unit within the Company which has as
its objective the commercialization of the technology resulting from this
program. In February 1998 the Company announced that it was distributing stock
of a newly formed, independent company, SonoSight, Inc., to ATL shareholders
as a tax-free stock dividend. This new company has as its objective the
commercialization of handheld ultrasound systems in the marketplace. The
Company expects to complete this spin-off in the second quarter of 1998.
 
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. A noninvasive procedure, ultrasound uses
high frequency sound waves to image the body's soft tissue, organs and blood
flow in real time. It is highly cost effective and can eliminate the need for
more invasive
 
                                       3
<PAGE>
 
and expensive procedures. ATL is one of the leading suppliers of diagnostic
ultrasound systems in the world. Its High Definition(TM) Imaging (HDI(R)) and
Apogee(R) product lines serve all major diagnostic ultrasound clinical
markets--radiology, cardiology, obstetrics/gynecology ("OB/GYN") and vascular
medicine--and a variety of newly emerging clinical markets such as
musculoskeletal diagnosis. 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 $2.5
billion worldwide market in 1997. 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 1997.
 
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. In July 1997 ATL introduced its fifth
generation digital ultrasound system to the premium ultrasound market, the HDI
5000 system.
 
ATL'S PRODUCTS
 
  HDI 5000 ULTRASOUND SYSTEM. In July 1997 ATL introduced its fifth generation
digital ultrasound system, the HDI 5000(TM) system, for the premium ultrasound
market. The HDI 5000 system is believed to be the world's most powerful
ultrasound system, capable of performing over 14 billion operations per
second, yet is the same physical size as ATL's previous premium performance
product, the HDI 3000 system. The new system incorporates a new, more powerful
digital beamformer incorporating four new ASICs (Application Specific
Integrated Circuits) which make possible ATL's MicroFine(TM) Grayscale Imaging
that provides more subtle tissue information and significantly reduced dot
size. At the heart of the HDI 5000 system is a patented new Doppler processor
which employs multi-dimensional broadband flow processing to provide new
levels of flow sensitivity for deep and small vessels. The HDI 5000 system
uses existing HDI scanheads and also operates with three new high-performance
broadband scanheads. The HDI 5000cv model of this new system provides advanced
performance for the premium cardiology market. The HDI 5000 and 5000cv systems
are both available as new ultrasound systems or as on-site upgrades to the HDI
3000 system worldwide, a uniquely flexible option for existing ATL customers.
The HDI 5000 system has been selected by NASA for launch on the International
Space Station in the year 2001, where the system will be operated by
astronauts to diagnose the effects of weightlessness and other characteristics
of spaceflight on the human body.
 
  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 high performance 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
 
                                       4
<PAGE>
 
diagnostic applications 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 examination 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. In March, 1997 ATL introduced Tissue Harmonic Imaging, a feature
derived from the Company's early research in imaging with harmonic contrast
agents, which reduces near field clutter in cardiac and deep abdominal images.
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 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.
 
  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 patented 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 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. The Apogee 800PLUS system is available in
a full cardiology configuration with three convex phased array scanheads, the
4-2C15 adult cardiology probe, the 6-3C13 small adult cardiology probe, and
the 8-5C11 pediatric cardiology probe, and integrated stress echo capability.
 
                                       5
<PAGE>
 
  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 systems in
the People's Republic of China. SIUI also acquired the exclusive right to
distribute the Apogee 800PLUS system in that country. The Company completed
this technology transfer in 1997. ATL continues to manufacture the Apogee
800PLUS system in Bothell, Washington for worldwide distribution outside of
China.
 
  IMAGE MANAGEMENT PRODUCTS. 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. The Nova MicroSonics
division manufactured and marketed networking, image acquisition and
measurement products for use in ultrasound data and image management by
hospitals, labs, clinics and physician offices. ATL had been working
cooperatively with Kodak for a number of years in ultrasound image management
product performance and distribution. The Company completed this transaction
in May, 1997. The Company continues to work closely with Nova MicroSonics as a
division of Kodak in the development and distribution of image management
products. The transaction did not result in a material gain or loss to the
Company.
 
  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, located in Reedsville, Pennsylvania. The Reedsville
site now develops and manufactures 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,
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
49% 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.
 
  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 premium HDI 5000 system, the
high performance HDI 3000 system, the mid-range HDI 1000 system, and the
Apogee 800PLUS system.
 
 
                                       6
<PAGE>
 
  Cardiology. The cardiology ultrasound, or echocardiography, application, at
approximately 29%, 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 5000cv system, 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 5000 and HDI 3000 systems for
perinatology, and the 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 7%, 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 5000, 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.
 
  Emerging applications. Other specialized applications for ultrasound
products, such as breast disease, musculoskeletal, and surgery, are included
in the above market percentages. ATL provides the HDI 3000 and HDI 1000
systems with the L10-5 and Entos CL10-5 scanheads for breast clinics and
orthopedic and sports medicine clinics, and with the Entos CL10-5, CT8-4 and
LI9-5 intraoperative scanheads for surgical suites. The HDI 3000 system is
available with the LLI9-5 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.
 
                                       7

  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 such as Tissue Harmonic Imaging and
three dimensional imaging. Typically, systems sold in the premium market are
equipped with a wide variety of specialty scanheads. The HDI 5000 and the HDI
5000cv systems are ATL's premium performance products.
 
  High Performance. The high performance market, comprising about 30% 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 system 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 Apogee 800PLUS
system.
 
  Low-End. The low-end market segment makes up the remaining 24% 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 34% 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. In 1997, following several years of stagnant
growth, the U.S. market began to manifest signs of new growth, spurred by the
introduction of premium ultrasound systems by a number of manufacturers and
the desire to replace aging equipment with up-to-date technology.
 
  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. 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
 
                                       8

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. In 1997 the European markets were
highly competitive and many U.S.-based manufacturers were disadvantaged in
Europe by the strengthening of the U.S. dollar.
 
  Japan. This market accounts for approximately 11% 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. The HDI
5000 system was introduced in the Japanese market in February 1998, joining
the HDI 3000 system as ATL's product offerings in that market.
 
  Asia Pacific and Latin America. The remaining geographic areas of the world
account for approximately 20% 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 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. The first product resulting
from this collaboration, the Advanced 3DI(TM) system, was introduced by ATL in
December 1997. The Advanced 3DI system operates interactively with ATL's new
HDI 5000 system which provides acquisition of ultrasound data for three
dimensional images. The HDI 5000 system also features fully integrated three
dimensional Color Power Angio(TM) imaging, first introduced by ATL on the HDI
3000 system in 1995, and also offers Integrated 3D Grayscale imaging, which
was introduced on the HDI 5000 system in December 1997.
 
MANUFACTURING
 
  The Company manufactures its ultrasound system products at its facility in
Bothell, Washington. Scanheads for ATL products are manufactured in both
Reedsville, Pennsylvania and Bothell, Washington. Reedsville also manufactures
certain specialty scanheads for other ultrasound companies and users.
 
  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 other materials and
component parts. The OEM scanheads purchased by ATL could be manufactured by
ATL, 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.
 
                                       9
<PAGE>
 
  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,
China, France, Germany, India, Italy, the Netherlands, Sweden, 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
distributors are managed through ATL's offices in Germany. Distributors
serving the Pacific Rim countries are served by ATL's office in Singapore.
Latin American and South American distributors are supported by ATL's U.S.
offices. Customers outside of the United States accounted for 49% of revenues
in 1997.
 
  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.
See 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 service organization sells and installs
upgrades for existing customers and provides training for biomedical
technicians so customers can service their own systems. The customer education
organization 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.
 
                                      10
<PAGE>
 
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 market and also
distributes a mid-range general imaging product. General Electric Medical
Systems, Inc. (GEMS) and Siemens Medical Systems, Inc., both of which have
extensive businesses in other medical imaging modalities, have in recent years
devoted increasing resources to development of their medical ultrasound
businesses. GEMS has recently announced plans to acquire the ultrasound
businesses of Elbit Ultrasound, which operates principally through
subsidiaries Diasonics and Vingmed Sound.
 
  The year 1997 was marked by major new product offerings by the Company and
Hewlett-Packard, continuing a trend which began in 1995. The many new product
offerings in recent years 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. Virtually all of the recent competitive product offerings
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, the Diasonics subsidiary of Elbit, Inc., and Siemens Medical
Systems, are divisions or subsidiaries of companies much larger than ATL. GEMS
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.
 
  In the spin-off of SonoSight, Inc., the Company's handheld ultrasound
division, the Company has agreed that it will not enter the handheld
ultrasound business for the next five years, a business generally defined as
ultrasound systems weighing ten pounds or less. ATL does have a license to use
SonoSight developments of the next three years in its non-handheld business
and SonoSight has corresponding rights to ATL developments in its handheld
business.
 
  The Company believes that significant competitive factors in the diagnostic
ultrasound market include the clinical performance of systems, cost
effectiveness of products, 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 or
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.
 
                                      11
<PAGE>
 
  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
copyright laws and confidentiality and licensing agreements. The Company's
proprietary digital beamformers are 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 U.S. Food and
Drug Administration ("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 design, 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 Quality System Regulations ("QSRs"). The Company is
also subject to periodic on-site agency 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 January, 1997
the FDA concluded a comprehensive inspection of the Company's Bothell,
Washington facilities and all Company products as a part of the approval
process for ATL's breast PMA supplement for the HDI 3000 system. The FDA has
notified ATL that the Company has satisfied the requirements of this
inspection.
 
  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 HDI 3000
system is 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 quality standards
for medical device design, manufacture, installation, and servicing known as
ISO 9001 standards. All of the Company's manufacturing facilities have
qualified for
 
                                      12
<PAGE>
 
ISO 9001 registration. In addition, several of the Company's international
sales and service subsidiaries received certification under the ISO 9002
standards for sales and service entities. ISO 9001 standards and related
medical device directives will become mandatory in Europe in June 1998. The
FDA has adopted the ISO 9001 standards as regulatory standards for the United
States in the form of the new QSR requirements, which go into effect in June
1998.
 
  ATL's HDI and Apogee products have received the European Community (CE) mark
in Europe. The CE mark means that the HDI products satisfy 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.
 
  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, 1997, the Company had 2,669 employees worldwide. None of
the Company's United States employees are 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 98021, consisting of 365,000 square feet
and is presently constructing a third building of 101,000 square feet which it
expects to occupy during the third quarter of 1998. 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. The Company also leases space in several buildings
in nearby business parks.
 
                                      14
<PAGE>
 
  The Company's Reedsville facility 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 unused space in the Ambler
building is currently listed for lease.
 
  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 those discussed above, and the Company believes its existing facilities
are sufficient to meet its near-term operating requirements.
 
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. In September 1997
the Federal Circuit Court of Appeals in Washington, D.C. upheld the decision
of the District Court. The Company completed payment of the assessed damages
and the supersedeas bond was released in the fourth quarter of 1997. The
Company accrued a provision in 1996 for the full amount of the damages awarded
and accrued interest during the appeal process. See Note 10 of the Notes to
the Consolidated Financial Statements on page 24 of the 1997 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.

"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS," the Company has recently decided to contribute capital of $18
million in cash to SonoSight, Inc. on the Distribution Date, and $12 million
in cash on January 15, 1999. SonoSight, Inc. is the wholly-owned subsidiary
consisting of ATL's handheld business which the Company intends to spin-off to
ATL shareholders through a tax-free stock distribution in the second quarter
of 1998. This change in capital structure was prompted by Nasdaq National
Market listing requirements.

Fellow Shareholders,

1997 was a remarkable year for ATL. The year's highlights were topped by the
worldwide launch of two major products, the HDI(R) 1000 and the HDI 5000
systems, each a milestone of technical achievement. These introductions
broadened the markets addressed by our successful all-digital HDI product line
to the mid-range and premium-performance markets. As the year came to a close,
the total worldwide installed base of HDI systems had grown to over 9,000
systems, firmly establishing ATL as the leader in all-digital ultrasound.

     With the increased investment required by the worldwide introductions of 
two new HDI systems, and the inevitable pause in orders as customers evaluated 
the new products, we were pleased to report 1997 net income of $21.2 million or
$1.41 per share, nearly matching the record profitability ATL achieved in 1996, 
excluding its non-recurring charge. For the year, revenues grew 3% to a record 
$431.2 million. With the momentum of the new products beginning to build at 
year-end, revenue growth accelerated to 9% in the fourth quarter, and we 
reported record quarterly revenues of $137.3 million, record gross margins of 
52.4% and record quarterly net income of $18.5 million or $1.23 per share.

GROWING WORLDWIDE DEMAND

The United States market for ultrasound came back to life during the year with a
robustness that exceeded our expectations. After years of little to no growth as
the country's health care delivery system streamlined and reconfigured itself, 
new demand for ultrasound was propelled by replacement of aging equipment and by
technology advances that opened new clinical applications offering better 
patient care, increased efficiency and lower health care costs.

     Over half of ATL's product revenues are derived from countries outside of 
the United States, a proportion that we expect to continue to increase even with
the resumption of U.S. market growth. These international markets were 
characterized by a variety of countervailing trends that made for lively 
conditions. The strong U.S. dollar held back positive revenue comparisons

2   1997 ATL Annual Report
<PAGE>
 
in Europe, although unit growth continued its upward trend, particularly in 
Italy, the United Kingdom, Scandinavia, Austria and the Benelux countries. 
Other key markets--Australia, China, Latin America and Eastern Europe--exhibited
excellent growth.

      In May 1997, we opened our 14th subsidiary, ATL China, with offices in 
Beijing, Shanghai, Guangzhou and Hong Kong. We anticipate that the Southeast 
Asian and Korean markets could remain challenging for some time. Although these
countries currently account for less than 10% of ATL's revenues, we believe they
offer substantial future opportunity, and we will continue to invest in building
our distribution channels there.

THE MOST POWERFUL ULTRASOUND SYSTEM IN THE WORLD

The Company's new premium-performance system, the HDI 5000, represents over a
decade of ATL investment and commitment to developing digital ultrasound
technology. Capable of performing more than 14 billion operations per second,
the HDI 5000 system provides a quantum leap in both the amount of diagnostic
information acquired and the ability to process it, giving health care providers
new information about the human body and how it works. The HDI 5000 is the first
system to apply supercomputed processing, patented new blood flow imaging
technology and adaptive system intelligence to diagnostic ultrasound. Of
fundamental value to thousands of customers worldwide is that their HDI 3000
system is fully upgradable, on-site, to the new HDI 5000 technology. With the
introduction of the HDI 5000, ATL customers now have the choice of two engines
on one platform, the HDI 5000 or the HDI 3000, demonstrating the platform's
inherent scalability.

      Customer shipments of the HDI 5000 began in November with prestigious 
institutions such as The Toronto General Hospital, Montefiore Medical Center of 
New York and Hutzel Hospital of Detroit placing multi-system orders for a 
complement of HDI 3000 and 5000 systems. NASA also elected to upgrade to the HDI
5000 technology for the International Space Station, scheduled for launch in the
year 2000. Astronauts will use the HDI 5000 system to perform

                                                     1997 ATL Annual Report   3
<PAGE>
 
sophisticated medical diagnostics while on board the Space Station. These images
will be transmitted to earth for scientists to study the effects of zero gravity
on blood flow, the heart and other organs. By year-end, the HDI 5000 system had 
been introduced to over 30,000 physicians at key medical congresses and clinical
symposia held in cities around the world.

ATL'S SECOND TECHNICAL INFLECTION POINT

We believe the introduction of the HDI 1000 system in February 1997 marked a 
second technological inflection point as significant as our decision to embark 
on an all-digital strategy 15 years ago. The HDI 1000 is a revolutionary 
software-based system that migrates ATL's acclaimed HDI broadband digital 
beamforming technology to the large and rapidly growing mid-range market for 
general imaging applications. ATL proprietary technology, MSM(TM) (Multitasking 
Software Management), replaces more than half of the ultrasound system's 
hardware components with sophisticated, flexible software.

     Designed for the new health care environment where increasing numbers of 
ultrasound examinations are performed in hospital satellite clinics, the HDI 
1000 system offers integrated Internet connectivity so that physicians can 
simultaneously view and consult on clinical cases with colleagues in other 
locations. During major medical meetings in the United States, Brazil and 
Austria, ultrasound images were transferred via Internet technology directly 
from the HDI 1000 system to laptop computers in other countries. The HDI 1000 
system has enjoyed early success in U.S. markets particularly in the Ob/Gyn 
segment, where ATL has established a strong franchise. During 1998, the feature 
set of the HDI 1000 will be further expanded to enhance its clinical utility.

ULTRA-PORTABLE ULTRASOUND

ATL's success in compressing ever-higher levels of performance into the same or 
smaller amount of space is based on our leadership in developing high density, 
proprietary microchips, ASIC's (Application Specific Integrated Circuits), and 
advanced system software. While ATL has employed these technologies primarily to
increase the power and resolution of ultrasound imaging, we have recognized an 
equally strong imperative to develop a smaller, less expensive device that could
be used as an examination tool and carried by the physician much like a 
stethoscope.

4   1997 ATL Annual Report
<PAGE>
 
     A year ago we formed a business division with responsibility for product 
and commercial market development of a handheld, all-digital ultrasound system. 
On February 11, 1998, we announced the spin-off of the Handheld Systems Business
Division as a tax-free stock dividend to our shareholders, on a one-for-three 
ATL shares basis. We believe a handheld ultrasound device for use as a 
first-stage medical examination tool will create entirely new markets for 
ultrasound that are intrinsically different from those served by ATL today as 
characterized by clinical use, the end user, manufacturing requirements and 
distribution channels. As an independent company, the Handheld Division will 
have the focus, speed and agility necessary to address this evolving set of new 
clinical and technical demands, thereby best serving our objective of enhancing 
long-term shareholder value. Through licensing agreements, ATL and the new 
company will continue to collaborate on technology innovations that will be of 
benefit to both companies.

THE EXPANDING CLINICAL REALM OF ULTRASOUND

In the final analysis, the case for advancing ultrasound technology must be 
justified by improved patient care--faster diagnosis, less physical and 
emotional trauma or lower cost. The great versatility of ultrasound leads to its
use in a multiplicity of diagnostic evaluations ranging from determining the 
adequacy of blood supply to the brain, to revealing changes in the vital organs 
of our bodies, to monitoring fetal health. A host of new ultrasound applications
are on the horizon--applications that will relieve the need to use radioactive 
isotopes and more expensive, invasive tests to understand what is happening 
inside the body.

     Working with clinicians and scientists, ATL is leading research in image 
acquisition and signal processing technologies that is expanding the diagnostic 
utility of ultrasound. One such area, 3D ultrasound imaging, provides more 
complete examination data while making it easier for a variety of medical 
specialists to more quickly grasp anatomical structures and relationships.

     Harmonic ultrasound imaging--with and without contrast agents--is another 
area offering great promise to replace expensive procedures by expanding the 
range of applications and patients that can be successfully studied. Physicians 
have found that ATL's Tissue Harmonic Imaging enables a dramatic reduction in a 
naturally occurring image artifact, or haze, caused by the interaction of 
certain tissue types and low frequency soundwaves,

                                                      1997 ATL Annual Report   5
<PAGE>
 
thereby reducing the need for further confirmatory diagnostic tests. ATL is also
at the forefront of research on a new generation of harmonic contrast agents. We
are collaborating closely with contrast agent manufacturers and over 50 medical
institutions around the world on the development of ultrasound techniques that
may enhance the effectiveness of agents to diagnose heart attacks faster and
more accurately, and also help in the detection and evaluation of tumors in the
abdomen, breast and prostate.

      We enter 1998 in the strongest position yet by any measure--market share, 
product line, technology and financial--in our history. For ATL Ultrasound, 1997
represented a feat of teamwork and accomplishment and the beginning of a new 
world of possibilities. My deepest appreciation and thanks go to all ATL 
employees. Finally, we thank you, our fellow shareholders, for your ongoing 
support.

                      CONDITION AND RESULTS OF OPERATIONS
- --------------------------------------------------------------------------------

RESULTS OF OPERATIONS

ATL is a worldwide leader in the development, manufacture, distribution and
service of diagnostic medical ultrasound systems and related accessories and
supplies.  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 medical cost containment, 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, upgradability, clinical versatility and ease
of use,  price competition is also an important factor.

ATL markets and services ultrasound products worldwide.  International revenues
accounted for 49% of 1997 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 net income in 1997 of $21.2 million or $1.41 per share.  In 1996,
ATL reported a net loss of $0.8 million or $0.06 per share.  Excluding a one-
time patent litigation charge and the related tax benefit, ATL earned net income
of $21.8 million or $1.47 per share in 1996.  Noteworthy business events
impacting results of operations for 1997 include successful introduction of the
HDI 1000 and HDI 5000 ultrasound systems, unfavorable fluctuations of foreign
exchange rates, sale of the Company's image management business and accelerated
expenditures related to the development of the Company's handheld ultrasound
technology.  All per share amounts are stated on a diluted basis and calculated
per Statement of Financial Accounting Standards (FAS) No. 128, Earnings Per
Share, which became effective in the fourth quarter of 1997.

</TABLE>
 
Revenues increased 3% to $431.2 million in 1997.  Product sales increased $8.9
million over 1996, reflecting the successful introduction of two major new
products, growth in the U.S. high-end cardiology market and the establishment of
new affiliate operations in China.  The phase out of older products from the
product line, such as the UM9 HDI and the Apogee CX/CX200 systems, in addition
to the unfavorable impact of foreign exchange rates and the sale of the
Company's image management business to Eastman Kodak partially offset the
revenue growth noted above.  The Company's new systems provided strong
incremental revenues in the mid-range and high-end markets.  The HDI 5000cv
system, which began customer shipments in November 1997, along with the
continued success of the HDI 3000cv drove revenue growth in the cardiology
market segment in 1997.  Service revenues increased $3.1 million from 1996 on
the continued growth in the worldwide installed base of ATL's products.

International revenues grew at rates in excess of 10% for all regions outside of
Europe which experienced a revenue decline over 1996 due to the unfavorable
impact of foreign exchange.  Overall, international revenue grew by 2% to $210.5
million during 1997.  The U.S. market showed signs of recovery in 1997 with
revenues growing to $220.7 million, up 4% from 1996.

1996 revenues increased 5% or $19.8 million over 1995 reflecting continued
success of the premium performance, all-digital HDI 3000 system, growth in the
cardiology market, initial benefits of ATL's strategic partnerships and
favorable changes in product mix toward the HDI 3000 and the mid-range Apogee
product lines.  The HDI 3000cv system, introduced in June 1995 with complete
cardiology capabilities, drove revenue growth in the cardiology market segment
in 1996.  Service revenues increased $6.1 million from 1995 on the continued
growth in the worldwide installed base of ATL's products.

Gross profit increased 4.3% in 1997 to $213.8 million, compared with $205.0
million in 1996.  Gross margin in 1997 was 49.6% compared with 48.9% in 1996.
The improvement in gross margin is due to the favorable shift in product mix to
the Company's higher margin HDI products achieved through the successful
expansion of this product family during 1997.  Gross profit rose on higher unit
volumes of the HDI 3000 and new sales of the 

                                                     1997 ATL Annual Report   13

HDI 1000 and HDI 5000 systems, but the growth was partially offset by lower
volumes of products being phased out and the impact of foreign exchange. 1996
gross margin improved to 48.9% compared with 46.2% in 1995. 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.

</TABLE>

*  1995 other expense, net, excludes a $6.2 million gain from an R&D joint
   venture and a $1.0 million B&O tax benefit.

Selling, general and administrative (SG&A) expenses increased by $5.7 million in
1997 and increased slightly as a percent of revenues to 29.9% compared with
29.3% in 1996 while remaining below the 30.0% level from 1995.  The increase in
SG&A is attributed primarily to product launch expenses for the HDI 1000 and HDI
5000 systems, market development expenditures in Asia and investments in the
Company's business information systems.  These increases were partially offset
by the impact of foreign exchange and the sale of the Company's image management
business to Eastman Kodak.  In 1996, SG&A expenses increased $3.0 million from
1995 as a result of 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.

ATL continued its commitment to advancing broadband digital ultrasound
technology by investing $59.7 million in research and development (R&D) expenses
in 1997.  As a percent of revenues, 1997 R&D expenses were 13.8% compared with
12.9% in 1996 and 12.6% in 1995.  Most of the increase in R&D expenses during
1997 related to two new product introductions as well as increased expenditures
related to the development of handheld ultrasound technology.  On February 20,
1997, ATL introduced the HDI 1000 system, a fundamentally new software based
mid-range system.  Shipments of the HDI 1000 system began in the second quarter
of 1997.  Some of the technology used in the HDI 1000 system was developed by
ATL as part of a R&D joint venture project with Hitachi Medical Corporation
(Hitachi) which began in the fourth quarter of 1995.  The technology resulting
from this joint venture is available to both ATL and Hitachi for new product
offerings and product features.  On July 22, 1997 ATL introduced the premium
performance HDI 5000 system.  Shipments of the HDI 5000 system began in the
fourth quarter of 1997.  R&D expenditures related to the development of handheld
ultrasound technology have increased significantly over 1996 as discussed below.
A working prototype is expected in the third quarter of 1998.

1996 R&D expenses increased $3.7 million from 1995 to $54.0 million.  The
increase in R&D expenses over 1995 was related to preliminary work on the HDI
1000 and 5000 systems that were under development at the time.

Other expense, net, was $0.1 million in 1997. This includes a gain on the sale
of the Company's image management business and foreign exchange losses.  In
1996, ATL reported $1.5 million of other expense, net.  This consists primarily
of Washington State Business and Occupation (B&O) tax expense as well as 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.

PATENT LITIGATION, RESTRUCTURING AND RELOCATION PROVISIONS

The Company accrued a patent litigation provision of $29.6 million in the second
quarter of 1996 in addition to $5.0 million previously accrued in 1994.  In
October 1997, the U.S. Court of Appeals affirmed the lower court judgment
awarding damages of $27.9 million, plus interest and legal fees, in favor of the
plaintiff.  The claim was paid in full as of December 31, 1997 (see Note 10 to
the Consolidated Financial Statements, Patent Litigation Provision).

In 1995, the Company consolidated its East Coast 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 (see Note 2 to the Consolidated
Financial Statements, Restructuring and Relocation).

available for investment compared with 1996 through the third quarter of 1997.
The higher interest expense in 1997 reflects nearly a full year of post-judgment
interest accrued on the damages awarded for the patent litigation claim.
Interest expense increased in 1996 compared with 1995 reflecting a partial year
of post-judgment interest accrued on the damages awarded for the patent
litigation claim (see Note 10 to the Consolidated Financial Statements, Patent
Litigation Provision).

and potential carryback opportunities.

The provision for income taxes includes benefits from the utilization of U.S.
federal and foreign tax loss carryforwards and carrybacks.  Tax loss
carryforwards of approximately $3.6 million remain at the end of 1997.

</TABLE>

The Company finances its operations primarily with internal resources, including
cash and short-term investments.  The Company held $30.8 million in cash and
cash equivalents at December 31, 1997.  Short-term borrowings represent working
capital lines of credit maintained at some of the Company's foreign subsidiaries
to facilitate intercompany cash flow.

As shown in the statement of cash flows, ATL used cash from operations of $16.7
million in 1997 compared with $45.2 million generated in 1996.  The change in
cash flows from operations primarily reflects the payment of patent litigation
damages of $37.4 million coupled with higher inventory and receivable balances.
Cash flows from investing activities included $17.5 million used for property,
plant and equipment purchases.  During 1997, exercise of employee stock options
and Employee Stock Purchase Plan issuances generated cash flow of $10 million.

The Company repurchased 343,000 shares of its own common stock in the open
market for $11.9 million in 1997 under share repurchase programs intended to
service ATL's benefit programs. The Company repurchased 289,000 shares totaling
$8.5 million in 1996.  In May 1997, the Board of Directors authorized the
Company to purchase up to 1,000,000 shares of its common stock, subject to
certain criteria.  A similar authorization was also granted in May 1996.

Long-term debt at December 31, 1997 was $12.3 million.  Interest rates on long-
term debt outstanding at December 31, 1997 averaged approximately 6.7%.

The Company began construction of a new 101,000 square foot building on its
corporate campus in August 1997.  The building's projected completion date is
scheduled for July 1998 and has an estimated cost of $15-16 million.  Initial
funding for the project will come from working capital with a transition to
long-term debt as the building reaches completion in 1998.

The Company intends to spin-off its handheld business after the first quarter of
1998 (the "Distribution"). In connection with the spin-off, the Company will
contribute capital of $15 million in cash on the Distribution date and $15
million in cash on January 15, 1999 (see Note 23 to the Consolidated Financial
Statements, Subsequent Event).

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, long-term debt and
cash generated from operations should be sufficient to meet the Company's
operating and capital requirements for 1998.

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 that 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 substan-

tial 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 programs are in compliance with international quality
system standards known as ISO 9000 standards.  ATL has maintained registration
under the ISO 9000 quality systems standards for its operations.  By 1998, all
medical device companies marketing products in the European Community will be
required to meet these standards. The current HDI product family has qualified
to display the European Community (CE) Mark.

The Company is currently reviewing its ultrasound product line and business
information systems for compliance with the Year 2000 issue. In general, the
Year 2000 issue exists because many computer systems and applications currently
use two-digit date fields to designate a year. As the century date change
occurs, date-sensitive systems may not recognize the year 2000.  The Company
believes the Year 2000 issue will not have a significant effect on its
operations.

SUBSEQUENT EVENT

On February 2, 1998, ATL's Board of Directors approved a plan to spin-off its
handheld business as an independent, publicly owned company.  The handheld
business incurred net operating expenses which totaled $6.0 million and $1.8
million in 1997 and 1996, respectively, which were included in the consolidated
results of ATL (see Note 23 to the Consolidated Financial Statements, Subsequent
Event).

FORWARD LOOKING INFORMATION

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

In 1998, the Company will continue to pursue its long-term goal of achieving a
return on shareholders' equity of 15%, compared with 1997 results of
approximately 10%.  The Company expects quarterly revenues and earnings in 1998
to be greater than 1997 levels, excluding first quarter expenses related to the
shareholder stock dividend of the handheld business, and to be principally
influenced by gross margin improvement during the first half of the year, and
additionally aided by revenue growth during the second half of the year.
Service gross margin is expected to be in the range of 40% to 42% for 1998.
Revenues for the full year are expected to be approximately 10% above 1997
levels, and gross margin for the full year is expected to be in the range of 50%
to 52%.  Operating expenses for 1998 are expected to be less than 10% above 1997
levels.  Diluted shares during the year are expected to rise from approximately
15.3 million shares during the first quarter of 1998 to 15.6 million by the end
of 1998. The Company is targeting earnings of around $2.35 per share for the
full year of 1998.

For the first quarter of 1998 the Company expects to realize a gross margin of
approximately 50% and to have earnings in the range of $0.10 to $0.13 per share,
which includes the effect of charges for the distribution of stock of the
handheld business to ATL shareholders.  These distribution expenses are expected
to be less than $1.5 million before tax.  The expenses for the handheld business
which are consolidated with ATL's other expenses during the first quarter are
expected to be in the range of $2 million to $3 million, or about $0.12 per
share.  When these expenses are considered together with the Company's expected
earnings for the first quarter of 1998, the Company is estimating the earnings
from its core business (excluding expenses associated with the handheld
business) for the quarter to be in the range of $0.29 to $0.32.

The above statements are forward looking statements that involve a number of
risks and uncertainties, and should be read in conjunction with the Company's
SEC filings and news releases.  Among the ongoing factors that could cause
actual results to differ materially from the above are the following
considerations.  The ultrasound market in some European countries remains
sluggish and certain Asian markets are troubled by turbulent economic
conditions, which 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, and the Company may lose sales to other product offerings.  These
factors may adversely impact the Company's sales volume or selling prices or
both.  Unanticipated events, such as delays in the Company's product development
and cost reduction programs, a delay in the distribution of the handheld
business, the unavailability of components critical to the Company's products
due to natural disasters, changes in vendor businesses or otherwise, economic
instability in Asian and other markets, the stronger U.S. dollar, delays in
receiving necessary regulatory approvals, or other unforeseen events could
adversely impact the Company's financial results for 1998.

Dollars in thousands, except per share data

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

     The consolidated financial statements include the accounts of ATL
Ultrasound, Inc. (ATL), formerly known as Advanced Technology Laboratories,
Inc., 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 is a worldwide leader in the development, manufacture,
distribution and service of diagnostic medical ultrasound systems and related
accessories and supplies. The Company sells its products to hospitals, clinics
and physicians for use in radiology, cardiology, women's health care, vascular,
musculoskeletal and intraoperative applications.

Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles (GAAP) 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 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 reduce
exposure to foreign currency fluctuations associated with settlement of
intercompany receivables and payables denominated in foreign currencies. Foreign
exchange contracts generally have maturities of less than one year and are
accounted for on the fair value method. Gains and losses resulting from these
instruments are recognized in the same period as the underlying foreign currency
transaction gains and losses and are included in other (income) expense, net. At
December 31, 1997 and 1996, the Company had foreign currency exchange contracts
to purchase totaling $19,029 and $15,632 and to sell totaling $40,863 and
$28,260, 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 cash
equivalents, 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 Cash Equivalents

     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.

Inventories

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

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 is 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 and Installment Sales Contracts

     The Company leases its ultrasound imaging products to customers under 
sales-type leases and installment sales contracts with terms ranging from two to
five years. The Company currently sells its contract receivables to outside
parties on a regular basis, the majority without recourse. 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 and stock purchase plans. The Company discloses proforma net income
(loss) and net income (loss) per share as if compensation cost had been
determined consistent with Statement of Financial Accounting Standard (FAS) No.
123, Accounting for Stock-Based Compensation.

Per Share Data

     In accordance with FAS No. 128, Earnings Per Share, the Company has
reported both basic and diluted net income (loss) per common share for each
period presented. Basic earnings per share (EPS) is calculated based on the
weighted average number of common shares outstanding during the period. The
computation of diluted EPS includes the effect of all dilutive potential common
shares outstanding. Conversion of dilutive potential common shares is assumed
based on the average market price of common shares outstanding during the
period.

     All previously reported earnings per share data have been restated to
conform with the provisions of FAS 128.

Reclassifications

     Certain amounts reported in previous years have been reclassified to
conform to the 1997 presentation.

2.   RESTRUCTURING & RELOCATION

     In 1995, the Company consolidated its East Coast 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 carrying value and could result in an impairment being recognized in the
future.

3.   SALE OF IMAGE MANAGEMENT BUSINESS

     Effective May 12, 1997, the Company sold its image management business to
Eastman Kodak. Revenues from this business were $2,074, $8,112 and $11,335 in
1997, 1996 and 1995, respectively.

10.  PATENT LITIGATION  PROVISION

     The Company accrued a patent litigation provision of $29,557 in the second
quarter of 1996 in addition to $5,000 previously accrued in 1994. The underlying
lawsuit was filed in the U.S. District Court for the Northern District of
California and concerned a patent on an electrical circuit used in three of
ATL's discontinued products sold primarily in the 1980's. The patent expired in
1994 and the circuit in dispute has never been used in any of ATL's current
product lines. In October 1997, the U.S. Court of Appeals affirmed the lower
court judgment awarding damages of $27,948, plus interest and legal fees, in
favor of the plaintiff. The claim was paid in full as of December 31, 1997. The
decision in this lawsuit did not adversely affect past or existing product
shipments and will not have any effect on the sale, use or service of any
current or past products.

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.

     The Company has reported an additional minimum liability of $587 and $632
at December 31, 1997 and 1996, respectively, representing the excess of the
accumulated benefit obligation over accrued pensions costs for the Supplemental
Plans. 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.

      The weighted average discount rate used in determining the end of year
acturial present value of the projected benefit obligation was 7.25% for 1997,
7.5% for 1996 and 7.25% for 1995. The assumed annual rate of increase in future
compensation levels was 7.5% for the first five years of service and 5%
thereafter. The expected long-term rate of return on plan assets was 10% for
1997 and 1996 and 9% in 1995.

      A 401(k) retirement savings plan is maintained for all U.S. employees. The
Company's contributions to this plan were $1,447, $1,376 and $1,317 in 1997,
1996 and 1995, respectively.

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

14.  SHAREHOLDERS' EQUITY

      At December 31, 1997, 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); the
Nonemployee Director Stock Option Plan and the Employee Stock Purchase 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 proforma amounts as indicated below:

     Under the Employee Stock Plans, 3,320,000 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, 1997, 97,300 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, 1997, 11,000 shares were available for grants under this plan.

     Under the 1986 Option, Restricted Stock, Stock Appreciation Right and
Performance Unit Plan, there were approximately 222,000 stock options
outstanding at December 31, 1997. Use of this plan for grants of stock, stock
options and other awards terminated in 1992.

     Proforma compensation expense is recognized for the fair value of each
option estimated on the date of grant using the Black-Scholes pricing model. The
following assumptions were used for option grants in 1997, 1996 and 1995,
respectively: expected volatility of 39%, 34% and 26%; risk-free interest rates
of 6.2%, 6.6% and 6.7%; expected lives of 4.25 years and zero dividend yield.

26   1997 ATL Annual Report

<PAGE>
 
     Effective January 1, 1997, the Company implemented an Employee Stock
Purchase Plan (ESPP) for the benefit of substantially all employees. Under the
terms of the ESPP, the Company is authorized to issue up to 300,000 shares of
common stock. The ESPP enables employees to purchase shares of ATL common stock
at a discounted price through after-tax payroll deductions. The Company does not
participate in the funding of this plan. The Company issued 67,852 shares for
employee stock purchases in 1997. At December 31, 1997, 232,148 shares were
available for purchase under this plan. Proforma compensation expense is
recognized for the fair value of each employee stock purchase right estimated on
the date of grant using the Black-Scholes pricing model. The following
assumptions were used for employee stock purchases in 1997: expected volatility
of 42%; risk-free interest rates of 5.1%; expected lives of .5 years; and zero
dividend yield. The weighted-average fair value of employee stock purchase
rights granted in 1997 was $12.59.

     In 1997, 1996 and 1995, 95,700, 70,000 and 14,680 shares, respectively, of
restricted stock were issued at par value. The weighted-average fair value of
those restricted shares granted in 1997, 1996 and 1995 was $37.02, $29.41 and
$15.80, respectively.

     The Company repurchased 343,000 shares of its own common stock in the open
market for $11,888 in 1997 under share repurchase programs intended to service
ATL's benefit programs. The Company repurchased 289,000 shares totaling $8,539
in 1996. In May 1997, the Board of Directors authorized the Company to purchase
up to 1,000,000 shares of its common stock, subject to certain criteria. A
similar authorization was also granted in May 1996.

     For Federal income tax purposes, the Company receives a deduction arising
from the exercise of employee stock options equal to the difference between the
fair market value at date of exercise and the original option grant price. This
tax benefit of $2,532 is reported as a credit to paid-in capital at December 31,
1997.

     The difference between taxes computed by applying the U.S. Federal income
tax rate of 34% to income (loss) before income taxes and the actual income tax
expense (benefit) follows:

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

     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.

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

     In determining the realizability of deferred tax assets, the Company
primarily considers its deferred tax liabilities, tax planning strategies,
future earnings and potential carryback opportunities.

     At December 31, 1997, the Company had net operating loss carryforwards for
statutory purposes of approximately $3,600, which begin to expire after 2000 or
have no expiration date.  The Company also has U.S. research and experimentation
credit carryforwards of approximately $11,400 with expiration dates from 1998
through 2012.  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 $11,100.  These earnings 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.  With the exception of Australia and the
United Kingdom, it is anticipated that the undistributed earnings will be
reinvested.  The tax impact of repatriating undistributed earnings from
Australia and the United Kingdom will be substantially offset by realization of
foreign tax credits.

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.  The technology resulting from this joint
venture is 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 $1,150 in 1997, $2,300 in 1996 and $1,000 in 1995 which is reported
in research and development expenses.

     In May 1996, ATL, the University of Washington, Harris Semiconductor and
VLSI Technology, Inc. entered into a consortium to develop a handheld ultrasound
device for use in military and commercial applications. The U.S. Government's
Advanced Research Projects Agency 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. ATL recognized funding of
$2,948 and $1,029 in 1997 and 1996, respectively, on this project which is
reported in research and development expense. See Note 23, Subsequent Event, for
a description of the tax-free distribution of handheld business shares to ATL
shareholders.

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
$641, $329 and $22 in 1997, 1996 and 1995, respectively.

     Other (income) expense, net, also includes Washington State Business and
Occupation (B&O) taxes of $83, $652 and $(606) in 1997, 1996 and 1995,
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.

     In 1997, other (income) expense, net includes a gain from the sale of the
Company's image management business as discussed in Note 3, Sale of Image
Management Business.  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, 1997 under long-term operating
leases for various types of property and equipment, with minimum aggregate
rentals totaling $15,958 as follows: $5,214 in 1998, $3,647 in 1999, $2,662 in
2000, $2,069 in 2001, $1,946 in 2002 and $420 thereafter.

     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 $8,449, $8,078 and $6,940 in 1997, 1996 and 1995, respectively.

Building Commitments

     The Company began construction of a new 101,000 square foot building on its
corporate campus in August 1997. On December 12, 1997, the Company signed an
addendum to its construction contract authorizing additional expenditures of up
to $10,000 on the project, substantially all of which remains outstanding at
December 31, 1997.

Legal Contingencies

     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.

     The 1996 results include a non-recurring expense of $29,557 for a patent
litigation provision and a $(6,900) related income tax benefit in the second

23.  SUBSEQUENT EVENT

     On February 2, 1998, the Company approved a plan to spin-off its handheld
business as an independent, publicly owned company. This transaction is to be
effected through the tax-free distribution of handheld business shares to ATL
shareholders after the first quarter of 1998 (the "Distribution"). The Company's
shareholders will receive one share of handheld business common stock for each
three shares of the Company's common stock held. In connection with the
Distribution, the Company will contribute to the handheld business, capital of
$15,000 in cash on the Distribution date and $15,000 in cash on January 15,
1999. The Company and the handheld business will also enter into a number of
agreements to facilitate the Distribution and the transition of the Company to
an independent business. A registration statement on Form 10 was filed with the
Securities and Exchange Commission in the name of Handheld Ultrasound Systems,
Inc. on February 13, 1998.

     To date, there have been no revenues from the sale of handheld ultrasound
devices.  The handheld business has been focused on the research, development
and commercialization of handheld technology and all business activities,
including U.S. Government development contract funding, have been reported in
the Company's operating expenses which totaled $5,994 and $1,764, respectively,
for the years ended December 31, 1997 and 1996.  The unaudited earnings per
share impact of the handheld business net operating expenses was $0.32 in 1997
and $0.12 in 1996.
