ITEM 1. BUSINESS
 
STRUCTURE OF THE COMPANY
 
  Advanced Technology Laboratories, Inc. ("ATL" or the "Company") is engaged in
the high-technology electronic medical systems business. ATL develops,
manufactures, markets and services diagnostic medical ultrasound equipment
worldwide. ATL conducts its business through two major wholly owned U.S.
subsidiaries, Advanced Technology Laboratories, Inc., a Washington corporation,
and Interspec, Inc., a Pennsylvania corporation. ATL operates through fourteen
international affiliates and through local distributors worldwide.
 
COMPANY HISTORY
 
  ATL was founded in 1969 and acquired by Squibb Corporation ("Squibb") in
1980. In 1982 Squibb acquired Advanced Diagnostic Research Corporation ("ADR"),
a Tempe, Arizona company which was a leader in obstetrical and abdominal
ultrasound, and A.B. Kranzbuehler ("Kranzbuehler"), a European ultrasound
manufacturer and distributor of ADR products in Europe. In 1986 Squibb
organized its medical equipment businesses, including SpaceLabs Medical, Inc.
("SpaceLabs"), a manufacturer and supplier of patient monitoring and clinical
information systems, under a corporate holding company, Westmark International
Incorporated ("Westmark") and spun the companies off through a distribution of
Westmark common stock to Squibb shareholders on January 2, 1987. In 1992
Westmark shareholders voted to separate Westmark into two publicly traded
companies comprising its 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 major operating subsidiary.
 
  ATL has acquired three companies with specific ultrasound expertise, products
and markets. In 1988 the Company acquired Nova MicroSonics which manufactures
and markets real time and off-line acquisition and measurement products for use
in ultrasound data and image management by hospitals, labs, clinics and
physician offices. In 1990 the Company acquired Precision Acoustic Devices,
Inc. ("PAD") which develops, manufactures and supplies high-performance
ultrasound transducers to industrial and medical imaging markets. In 1993 the
Company relocated PAD's Fremont, California operations to Bothell, Washington
and sold the OEM transducer business of PAD to Blatek, Inc., a transducer
company in State College, Pennsylvania.
 
  In May 1994 the Company completed the acquisition of Interspec, Inc.
("Interspec"), a 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. On February 15, 1995 the Company announced that it would
consolidate the Company's Interspec operations in Ambler Pennsylvania with
ATL's headquarters in Bothell, Washington and anticipates completing this
consolidation during the second half of 1995.
 
THE ULTRASOUND BUSINESS
 
  ATL develops, manufactures, markets and services diagnostic medical
ultrasound systems that are widely used in a number of medical applications to
assist the physician in monitoring and diagnosing a variety of conditions, such
as tumors, inflammations, obstructions, cardiovascular diseases, fetal
development, and surgical assessment. Ultrasound systems provide a safe,
noninvasive and painless means of observing soft tissues and internal body
organs and assessing blood flow through the heart and vessels. ATL is one of
the leading suppliers of diagnostic ultrasound systems in the world. Its High
Definition (TM) Imaging (HDI (TM)),
 
                                       3
<PAGE>
 
Apogee, and Ultramark (R) product lines serve all major diagnostic ultrasound
clinical markets--radiology, cardiology, obstetrics/gynecology ("OB/GYN") and
vascular medicine. These product lines span a range of system prices from mid
to premium priced ultrasound products.
 
  Diagnostic ultrasound systems, which are sold for use in hospitals, clinics
and physicians' offices, represented an estimated $2 billion worldwide market
in 1994. The total medical imaging industry is estimated to be over $8 billion
worldwide in 1994.
 
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 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 premium system processing units are characterized by their
ability to fully process broadband signals characteristic of the body's tissues
digitally. ATL has been a pioneer in ultrasound digital technology and
introduced the industry's first digital beamforming processor in 1988.
 
 Ultrasound Characteristics
 
  Ultrasound offers several important advantages compared with other medical
imaging modalities.
 
  Safety. Physicians can often diagnose disease without using invasive
procedures or materials, ionizing radiation or exploratory surgery.
 
  Cost effectiveness. Ultrasound is generally less expensive to purchase, costs
less per patient examination, and requires little or no patient preparation
compared to other imaging modalities such as angiography, computed tomography
("CT"), magnetic resonance imaging and positron emission tomography ("P.E.T.").
 
  Real-time. Ultrasound examinations provide the physician with live, real-time
images of anatomy and physiology, which yield more diagnostic information and
can facilitate a faster diagnosis than static images of other imaging
modalities.
 
  Compared with high-energy modalities such as x-ray and gamma-ray systems,
ultrasound has difficulty imaging through air or bone and generally does not
image the lungs or bones. Due to acoustic properties such as scattering or
attenuation, ultrasound may not provide the clarity of more expensive
modalities such at CT and magnetic resonance imaging in certain applications.
However, by reason of its clinical efficacy, safety, versatility, ease of use
and economy, ultrasound is often the first imaging examination ordered by a
diagnosing physician and is typically the preferred imaging method for soft
tissues examination.
 
ATL'S PRODUCTS
 
  HDI (TM) 3000 ULTRASOUND SYSTEM. In October 1994 ATL introduced its fourth
generation digital ultrasound system, the HDI (TM) 3000 system. The premium HDI
3000 system was designed to address the economic imperatives of the evolving
health care environment in the United States and international markets. The HDI
3000 system operates with a full array of broad bandwidth scanheads, including
the new Entos CL 10-5 Intraoperative scanhead designed for surgical use and now
reported in use for the diagnosis of musculoskeletal injuries in sports
medicine. The HDI 3000 system is lighter in weight than competitive systems,
providing greater mobility and enabling it to be easily moved to the bedside of
critical care patients.
 
                                       4
<PAGE>
 
The HDI 3000 system also features a new, more intuitive, ergonomically designed
set of operator controls, which enable an ultrasonographer or physician to
quickly gain confidence in operating the system and performing diagnoses. The
HDI 3000 system provides interactive control screens with diagnostic procedures
selectable at the touch of a button. This feature, called Tissue Specific (TM)
Imaging, optimizes system performance for the selected diagnostic procedure.
The HDI 3000 system offers full Doppler capability, including improved Color
Power Angio imaging features.
 
  In addition to the introduction of the HDI 3000 system and the CL10-5
scanhead in October 1994, ATL introduced two other new broadband scanheads
which expand the HDI system's clinical capabilities: the P7-4 broadband phased
array scanhead for pediatric cardiology and neonatal imaging, and the
multiplane transesophageal MPT7-4 scanhead for cardiac imaging. Shipments of
the MPT7-4 will begin in 1995. These product introductions followed the 1993
introduction of Extended Signal Processing (ESP (TM)) technology and four new
broadband scanheads for the Ultramark 9 HDI system. ESP is a standard feature
of the HDI 3000 system.
 
  ULTRAMARK 9 HIGH DEFINITION IMAGING (HDI) SYSTEM. The Ultramark 9 system with
High Definition Imaging ("HDI") is ATL's high performance product. Introduced
in April 1991, the system contains a digital beamformer which allows high
resolution images and captures a broad bandwidth of tissue signatures. The
Ultramark 9 HDI system also offers a series of high performance scanheads,
including a line of broad bandwidth scanheads which provide a broad range of
clinical applications for the system and substantially enhance the system's
competitive performance. In 1993 the performance of the Ultramark 9 HDI system
was enhanced with the addition of the ESP performance option, providing
improved, speckle reduced image clarity and a wider variety of scanheads for
the system. That year also marked the introduction of the Ultramark 9 HDIcv
system, a high performance system specially configured for the cardiology,
shared services and internal medicine markets. The Ultramark 9 HDI system
operates with a variety of broad bandwidth scanheads including the P7-4 and P5-
3 scanheads, which extend broad bandwidth capability to pediatric cardiology
and small adult applications; the C7-4 scanhead, which is a broad bandwidth
scanhead for abdominal and obstetrical applications; the C4-2 scanhead, which
provides the penetration required for deep abdominal and obstetrical
applications; and the L7-4 scanhead, which provides broad bandwidth scanning in
vascular applications. These scanhead offerings complement the other four
members of ATL's family of broadband scanheads, including the L10-5 linear
array scanhead, the A6-3 annular array scanhead, the P3-2 cardiovascular phased
array scanhead, and the C9-5 intracavitary scanhead.
 
  APOGEE (R) 800 SYSTEM. In 1994 the Company introduced the mid-range Apogee
800 high value imaging system for the radiology and internal medicine markets.
Manufactured by Interspec, the Apogee 800 system offers features normally found
on high performance systems. These include ease of use, and a system affording
high mobility at a moderate price. The Apogee 800 system can be configured to
address a broad array of clinical needs of the radiologist, internal medicine
specialist, and vascular physician.
 
  APOGEE CX 200 AND CX SYSTEMS. The Apogee CX 200 and CX systems are moderately
priced echocardiography systems designed for the hospital and high-end office
markets. The systems offer full imaging, color flow mapping, spectral Doppler
scanning, and digital image archival and can be equipped to perform stress echo
examinations. The Apogee CX 200 and CX systems are also designed to support
multiplane transesophageal echo examinations.
 
  ULTRAMARK 9 DP ULTRASOUND SYSTEM. The Ultramark 9 system was introduced in
1988 as a full featured, color Doppler, multipurpose ultrasound system
incorporating ATL's proprietary digital beamforming technology. In November
1990 the product was enhanced with a number of features known as the Digital
Plus ("DP") package. With the success of the Ultramark 9 HDI system, the
Company has discontinued the manufacture of new Ultramark 9 DP systems. ATL's
entire installed base of Ultramark 9 DP systems can be upgraded with the HDI
option, continuing ATL's commitment of upgradeability to its customers.
 
                                       5
<PAGE>
 
  ULTRAMARK 4 ULTRASOUND SYSTEM. This highly portable gray scale and Doppler
system is the Company's principal product for private OB/GYN offices and is
also used in medical institutions worldwide. This product has various
configurations that cover a range of prices from $25,000 to $60,000. Recent
major introductions include Cineloop image review, curved-array scanhead
technology and a multifrequency intravaginal scanhead.
 
  IMAGE MANAGEMENT PRODUCTS. The Company's Nova MicroSonics division develops,
manufactures and markets a complete line of ultrasound image management
products for use in the acquisition, storage, display and management of
ultrasound information. In 1994 the Company introduced the Access (TM) Image
Management System which provides efficient printing, automated image archival
and retrieval and reduced patient examination times through an ultrasound open
network architecture. The Access system connects to many types of ultrasound
systems, printers or other image management products, facilitating improved
diagnostic consultations within and between hospitals. Through an agreement
with Eastman Kodak Company, the Access system participates in the market for
image management systems addressing all diagnostic imaging modalities. For
cardiac applications, the Nova MicroSonics technology facilitates the review
and comparison of images produced at different times during a cardiac study,
expanding the diagnostic applications of echocardiography to the detection of
coronary artery disease. The ImageVue/DCR Workstation is a state-of-the-art
digital ultrasound image management system. This workstation performs analysis
and review of ultrasound exams conducted from a variety of ultrasound systems.
The Image LAN Network provides network connection between ultrasound systems,
workstations, printers and other medical imaging devices.
 
  SCANHEADS. ATL believes that its internal resources devoted to development
and manufacture of ultrasonic scanheads make it one of the largest ultrasound
scanhead manufacturers in the world. ATL's capabilities in scanhead design and
manufacture were enhanced in 1994 with the addition of the Echo Ultrasound
division of Interspec. The Echo Ultrasound division produces scanheads for the
ATL and Interspec products, and also offers scanheads on an OEM basis 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 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.
 
  Radiology. The radiology application, at approximately 45%, 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 abdomen. 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 Germany, the internal medicine segment requires systems
which include cardiac imaging capability.
 
                                       6
<PAGE>
 
  ATL's radiology product offerings include the HDI 3000 system, the Apogee 800
system, and the Ultramark 9 HDI system. Ultramark 9 HDI systems are sold as new
and as refurbished (used) systems. Ultramark 9 DP systems are sold on a
refurbished basis.
 
  Cardiology. The cardiology ultrasound, or echocardiography, application, at
approximately 35%, 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.
 
  ATL's cardiology product offerings include the Ultramark 9 HDIcv system and
the Apogee CX products.
 
  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. The advent of ATL's broadband digital imaging
technology with the ESP option (see "ATL's Products") has enabled physicians to
visualize details of fetal development at earlier stages of pregnancy than had
previously been possible.
 
  ATL's OB/GYN product offerings include the HDI 3000, the Ultramark 9 HDI
system, refurbished Ultramark 9 DP systems, and the Ultramark 4 system for the
office market.
 
  Vascular. The smallest of the primary clinical markets for ultrasound
systems, at approximately 6%, is the vascular ultrasound application, primarily
practiced in the United States and Western Europe. Most vascular ultrasound
examinations are performed in hospitals.
 
  Vascular ultrasound studies utilize real-time imaging, Doppler and color
Doppler information to identify plaque deposits and their characteristics,
clots, and valve competence in blood vessels. Most vascular examinations are
performed on the body's extremities, cerebrovascular and deep abdominal
regions.
 
  ATL's vascular product offerings include the HDI 3000, the Ultramark 9 HDI
system, the Apogee 800 system, and refurbished Ultramark 9 DP systems. The new
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.
 
  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.
 
                                       7
<PAGE>
 
  Premium Performance. The premium market segment is characterized by
ultrasound systems that typically sell for over $150,000 per unit. These
systems provide the physician with superior definition of subtle tissue
characteristics and incorporate high resolution gray scale imaging, advanced
color velocity, power, and spectral Doppler capability, image acquisition
storage, display and review capability, advanced automation capabilities, and
other features providing additional clinical utility. Typically, systems sold
in the premium market are equipped with a wide variety of specialty scanheads.
The HDI 3000 system is ATL's premium performance system.
 
  High Performance. The high performance 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 to $150,000 per unit and generally include advanced measurement and
analysis software, image review capabilities, and a variety of scanhead
offerings. The Ultramark 9 HDI and Ultramark 9 HDIcv systems are ATL's entries
in this market segment.
 
  Mid-Range. The mid-range market segment is characterized by ultrasound
systems that sell between $40,000 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 Apogee 800
system, the Apogee CX 200 and CX systems, and refurbished Ultramark 9 DP and
Ultramark 9 HDI systems.
 
  Low-End. The low-end market segment is characterized by basic black and white
imaging systems that sell below $40,000 per unit. These systems provide limited
diagnostic information and are used primarily for monitoring fetal development
and in other 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's
entry in the low-end market is the Ultramark 4 system.
 
  GEOGRAPHIC AREAS. The ultrasound market is divided into four major geographic
markets.
 
  United States. The United States, at 38% of the market, is the largest single
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. In
1993 and 1994, with the emphasis in the United States turning to more efficient
healthcare delivery and managed care and the consolidation of healthcare
organizations, the U.S. market has become increasingly value conscious.
 
  Europe. The European market, at 30% of the market, is the second largest
market for ultrasound systems. European health care systems are more
centralized than the United States market and are often subject to more rigid
governmental regulation. In 1994 the European markets proceeded through one of
the more pronounced recessionary cycles for healthcare in many years. This
effect has been moderated somewhat by the more regulated character of
healthcare in Europe, providing more stability to the European markets. Value
consciousness and organized healthcare has been characteristic of European
markets for a number of years, unlike the United States where these effects are
of relatively recent origin. The addition of the Interspec products to ATL's
product lines have significantly increased the presence of ATL in the European
markets.
 
  Japan. This market accounts for approximately 16% of worldwide ultrasound
sales. Its complex distribution system is highly competitive and Japanese
manufacturers account for almost all sales.
 
  Asia Pacific, Latin America and Canada. The remaining geographic areas of the
world account for approximately 15% of the market. The Australian and Canadian
markets are similar in structure to those of the European countries. Parts of
Asia and Latin America represent some of the fastest growing areas for high
performance and mid-range ultrasound products. The remainder of this group are
mostly developing countries with limited resources to devote to health care.
Many ultrasound systems sold in these regions are mid-range systems,
refurbished systems or new low-priced Japanese systems. The Asia Pacific and
Latin America markets are among the Company's fastest growing markets.

RESEARCH AND DEVELOPMENT
 
  In 1991 the Company instituted a multi-center study at a number of
institutions in Europe and North America to evaluate the ability of the
Ultramark 9 HDI system to distinguish benign and malignant breast disease.
These studies were concluded in 1993. Based upon the findings of these studies,
in February 1994 the Company submitted a Premarket Approval ("PMA") application
to the U.S. Food and Drug Administration ("FDA") for the use of HDI technology
in the differentiation of solid breast masses. The Company believes this to be
the first PMA application submitted to the FDA for diagnostic ultrasound. The
Company has received expedited handling of the PMA application by the FDA, and
is presently awaiting the FDA's commentary on its PMA application, which is
expected to lead to a review of the application by an FDA panel. The time
required for the application to be processed by the FDA is unknown, although
such applications typically require twelve to twenty-seven months. There can be
no assurances that product clearance under the PMA will ultimately be realized.
 
  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. 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.
 
MANUFACTURING
 
  The Company manufactures its ultrasound system products at facilities in
Bothell, Washington and Ambler, Pennsylvania. On February 15, 1995 the Company
announced that it would consolidate the Company's Interspec operations in
Ambler, Pennsylvania with ATL's headquarters in Bothell, Washington and that it
anticipates completing this consolidation during the second half of 1995. The
image management systems of Nova MicroSonics are manufactured in Nova's New
Jersey facilities. The Echo Ultrasound division of Interspec is located in
Reedsville, Pennsylvania.
 
  The Company purchases certain specialty 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 specialty scanheads and many of the materials and
components used by ATL in the manufacture of ultrasound equipment are available
from more than one source of supply. Certain components, however, are single
sourced, such as crystals and hybrid and integrated circuits which are critical
to the quality and manufacture of ultrasound equipment. 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
manufacturing production 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.
 
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, with the
exception of the third-party business of Nova MicroSonics, the Company markets
its products through its direct sales organization. The United States 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.
 
                                       9
<PAGE>
 
  The Company markets its products internationally through its direct sales and
service operations in Argentina, Australia, Austria, Belgium, Canada, France,
Germany, Italy, the Netherlands, Hong Kong, Singapore, and the United Kingdom.
In addition, the Company markets its products in India through a joint venture
with Indchem Electronics. In January 1995 the Company announced that it had
reached an agreement to increase its position in its India joint venture to a
majority share. Other principal markets are covered through a distributor
network. European, Middle Eastern and African dealers are managed through ATL's
offices in Germany. Distributors serving the Pacific Rim countries, Latin
America and South America are managed from Bothell, Washington. Customers
outside of the United States accounted for approximately 46% of revenues in
1994.
 
  The Company's marketing efforts emphasize the development of strong
relationships with key medical professionals, participation in national and
regional meetings and conventions for physicians and hospitals, direct mail
advertising, journal advertising and sponsorship of educational programs.
 
CUSTOMER SUPPORT AND WARRANTY
 
  The Company warrants its new and used products for all parts and labor
generally for one year from the date of original delivery. The Company offers a
variety of post-warranty service agreements permitting customers to contract
for the level of equipment maintenance they require. Alternatively, customers
can contact ATL as needed and receive service at rates based on labor and cost
of parts. The Company's warranty costs are included in cost of product sales in
Item 8, Financial Statements and Supplementary Data.
 
  The Company maintains its own customer support organization in the United
States and other countries where the Company has direct operations. Local
dealers and distributors provide service and support in other countries. The
Company provides manuals and expedites delivery of repair parts to all
geographic locations from its facility in Bothell, Washington, with the
assistance of its direct operations in Europe.
 
  The Company's customer service organizations are an integral part of its
sales effort because a customer's decision to purchase a particular product is
based in part on the availability and reputation of the service for that
product. In addition, the customer support group sells and installs upgrades
for existing customers and provides training for biomedical technicians so that
customers can service their own systems. The customer support group also
provides customer education programs on clinical applications and the use of
the Company's products.
 
COMPETITION
 
  The ultrasound market is competitive. The Company competes worldwide in the
major clinical applications of the ultrasound market, in each price range and
in each major geographic market. Four companies, ATL, Toshiba Corporation's
Medical Systems Group, 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 approximately equal
market shares. Each of the Company's primary competitors initially participated
in only one or two of the clinical ultrasound markets (such as radiology or
cardiology), but all are increasingly seeking to sell their ultrasound products
in additional markets.
 
  In addition to the Company's primary competitors, the large, multi-modality
companies of the medical imaging industry--the Medical Systems Group of General
Electric Company, Siemens Medical Systems, Inc. and Philips Medical Systems,
Inc.--have signaled their intention to become more competitive in the
ultrasound market. General Electric stepped up its participation in ultrasound
in November 1993 with the announcement of a new digital ultrasound system, and
has recently announced that it has contracted with
one of the nation's large hospital networks to assist with the acquisition and
servicing of the network's diagnostic equipment. Philips has announced its
plans to collaborate in ultrasound with Hewlett-Packard.
 
                                       10
<PAGE>
 
Siemens has located its central world ultrasound facility to Issaquah,
Washington, approximately twelve miles from ATL's headquarters. Elbit, Inc., an
Israeli supplier of a broad range of diagnostic imaging equipment, increased
its presence in ultrasound in 1994 with the acquisition of Diasonics, Inc.
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.
 
  The Company believes that significant competitive factors in the diagnostic
ultrasound market include the clinical performance of systems, depth of product
line, reputation for technology leadership, upgradeability to advanced
features, availability of Company-provided purchase financing, and reliability
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.
 
  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
could adversely affect the ultrasound industry. Nevertheless, the Company
believes that ultrasound's inherent advantages of safety, cost-effectiveness
and real-time imaging will continue to make ultrasound a primary imaging
modality.
 
PATENTS, TRADEMARKS AND LICENSES
 
  The Company has obtained patents on certain of its products and has applied
for patents which are presently pending. The Company has also sought trademark
protection for the brand names of the products it currently markets. There can
be no assurance that any additional patents will be issued or that trademark
protection will be granted and maintained.
 
  Certain critical technology incorporated in the Company's products, including
software algorithms, broad bandwidth scanhead technology and ASIC technology,
is protected by copyright laws and confidentiality and licensing agreements.
The Company's proprietary digital beamformer is protected by confidentiality
agreements, copyright and trade secret law.
 
  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 that the Company pay substantial damages or delete certain features
from its products or both. While such claims could temporarily interrupt the
Company's ability to ship affected products, the Company believes that any such
interruption can be overcome by technical changes to product features. See Item
3, Legal Proceedings, below.
 
GOVERNMENTAL REGULATION
 
  Product Regulation. The Company's products are subject to extensive
regulation by numerous governmental authorities, principally the FDA and
corresponding state and foreign agencies, and to various domestic and foreign
electrical safety and emission standards. The Company's manufacturing
facilities and the manufacture of its products are subject to FDA regulations
respecting registration of manufacturing facilities and compliance with the
FDA's Good Manufacturing Practices regulations. The Company is also subject to
periodic on-site inspection for compliance with such regulations. The Company's
ability to obtain timely FDA export and new product approvals is dependent upon
the results of such inspections. In 1994 the FDA concluded inspections of the
Company's Allendale, New Jersey facilities of Nova MicroSonics and its Bothell,
Washington facilities. The FDA also has broad regulatory powers with respect to
preclinical and clinical testing of new medical products and the manufacturing,
marketing and advertising of medical products.
 
                                       11
<PAGE>
 
  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 premarket approval 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 premarket approval 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 required only 510(k) clearance. In October 1994 the
Company received 510(k) clearance to market its new HDI 3000 system.
 
  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.
 
  The Company's regulatory compliance programs have been expanded to encompass
verification of the Company's compliance with international standards for
medical device design, manufacture, installation, and servicing known as ISO
9001 standards. In 1994, four of the Company's five manufacturing facilities
qualified for 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 will
become mandatory in Europe in 1999. The FDA is in the process of adopting the
ISO 9001 standards as regulatory standards for the United States, and it is
anticipated these standards will be phased in for U.S. manufacturers of medical
devices over a period of time.
 
  Federal, state and foreign regulations are constantly undergoing change. In
1994 the U.S. government continued its consideration of healthcare system
reform. The national focus on possible healthcare legislation has caused U.S.
ultrasound customers to become more cautious in making expenditures and
investing in capital equipment. In addition, the U.S. healthcare 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 healthcare providers for
diagnostic testing services and other services for which the providers may seek
reimbursement from third-party payors, 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 payors. 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 payors 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 payors worldwide, including governmental agencies, are under
increasing pressure to contain medical costs. Limits on reimbursement or other
cost containment measures imposed by third-party payors 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
 
                                       12
<PAGE>
 
regulation would have on the Company. Many of ATL's ultrasound systems are used
in an outpatient setting, replace higher-cost imaging modalities or enable a
hospital or clinic to receive higher payments for services commensurate with
the higher level of diagnostic information provided.
 
  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, 1994, the Company had 2,630 employees. None of
the Company's United States employees is covered by collective bargaining
agreements, and the Company considers its employee relations to be
satisfactory.
 
FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES
 
  Information set forth in "Geographic Segment Information" of the Notes to the
Consolidated Financial Statements contained in Note 20 on page 26 of the 1994
Annual Report to Shareholders is incorporated by reference herein.
 
EXECUTIVE OFFICERS OF THE REGISTRANT
 
  Information set forth in Part III, Items 10-13 found on page 15 of this Form
10-K are incorporated herein by reference in response to the information
required by this item.
 
ITEM 2. PROPERTIES
 
  The Company owns premises at 22100 Bothell Everett Highway, Bothell,
Washington 98041, consisting of 285,000 square feet. These premises include the
Company's corporate headquarters and a major manufacturing facility, as well as
the Company's research and development, sales, service, marketing and
administrative functions. A number of these functions are being moved to the
building on an adjoining property which the Company purchased in December 1994
for approximately $11.5 million, consisting of 80,000 square feet. The
additional space provided by the new building makes possible the consolidation
of Interspec's Ambler, Pennsylvania operations into those of the Company's
headquarters facilities, as well as the consolidation of operations occupying
another 41,000 square feet in an adjoining business park. See "Subsequent
Event" of the Notes to the Consolidated Financial Statements contained in Note
22, included in Item 8 of this Form 10-K. The Company expects to sell the
Ambler, Pennsylvania building after the consolidation of operations there has
been fully completed in late 1995.
 
  The Company's Nova MicroSonics facility occupies approximately 33,000 square
feet in leased buildings in Allendale, New Jersey and Indianapolis, Indiana,
and the Echo Ultrasound division of Interspec occupies 63,000 square feet in a
building owned by the Company in Reedsville, Pennsylvania.
 
  In 1994, the Company sold property formerly used as the Company's
manufacturing facility in Germany for $3.2 million. 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 which
have not yet been disposed of, 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 product liability 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 subsequent to 1986 are covered by
the Company's insurance policies. The Company
 
                                       13
<PAGE>
 
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 November 1992, a U.S. District Court in California granted a motion by SRI
International, Inc. ("SRI") requesting partial summary judgment on a patent
infringement claim relating to an electrical circuit alleged to be used in the
Company's Ultramark 4 system and two discontinued products. The patent expired
in 1994. In December 1994 the U.S. Federal Circuit Court of Appeals affirmed
the summary judgment obtained by SRI. A jury trial to determine a damage award
commenced in the District Court in California in March, 1995 but was suspended
after two days of trial for assignment of the case to a new judge. SRI is
claiming royalties for past sales of these product and an enhancement of
royalties for willful infringement. 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. Information set forth in Notes to
the Consolidated Financial Statements contained in Note 19 on page 26 of the
1994 Annual Report to Shareholders is incorporated by reference herein.
 
  The Company is involved in various other legal actions and claims arising in
the ordinary course of business. The Company believes the resolution of these
matters individually and in the aggregate will not have a material adverse
effect on the Company's financial condition.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
 Advanced Technology Laboratories, Inc.:
 
  Under date of February 10, 1995 we reported the consolidated balance sheets
of Advanced Technology Laboratories, Inc. and subsidiaries as of December 31,
1994 and 1993, and the related consolidated statements of operations,
shareholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1994, as contained in the 1994 annual report to
shareholders. These consolidated financial statements and our report thereon
are incorporated by reference in the annual report on Form 10-K for the year
1994. In connection with our audits of the aforementioned consolidated
financial statements, we also audited the related consolidated financial
statement schedules as listed in the index referred to in Part IV, Item 14(2)
of the Form 10-K report. These consolidated financial statements and financial
statement schedules are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statement schedules based on our audits.
 
  In our opinion, such financial statement schedules, when considered in
relation to the basic consolidated financial statements taken as a whole,
present fairly, in all material respects, the information set forth therein.
 
  The Company changed its method of accounting for investments to adopt the
provisions of Statement of Financial Accounting Standards (SFAS) No. 115,
Accounting for Certain Investments in Debt and Equity Securities, at January 1,
1994.

SECTION 7.  Order of Business

for business to be properly brought before an annual meeting by a stockholder,
the stockholder must have given written notice thereof, either by personal
delivery or by certified or registered United States mail, postage prepaid, to

Originally Scheduled Date (as such term is defined below) of such meeting;
provided, however, that if such annual meeting of stockholders is held on a date
--------  -------                                                               
earlier than the first Tuesday in May, such written notice must 
<PAGE>
 
be given within 10 days after the first public disclosure (which may be by a
public filing by the Corporation with the Securities and Exchange Commission)
of the Originally Scheduled Date of the annual meeting. Any such notice shall
set forth as to each matter the stockholder proposes to bring before the
annual meeting (A) a brief description of the business desired to be brought
before the meeting and the reasons for conducting such business at the meeting
and, in the event that such business includes a proposal to amend either the
Certificate of Incorporation or By-Laws of the Corporation, the language of
the proposed amendment, (B) the name and address of the stockholder proposing
such business, (C) a representation that the stockholder is a holder of record
of stock of the Corporation entitled to vote at such meeting and intends to

No business shall be conducted at an annual meeting except in accordance with
this paragraph, and the chairman of any annual meeting of stockholders may
refuse to permit any business to be brought before such annual meeting without
compliance with the foregoing procedure. For purposes of these By-Laws, the
"Originally Scheduled Date" of any meeting of stockholders shall be the date
such meeting is scheduled to occur in the notice of such meeting first given
to stockholders regardless of whether such meeting is continued or adjourned
and regardless of whether any subsequent notice is given for such meeting or
the record date of such meeting is changed.

     (b)  Special Meetings.  At a special meeting of the stockholder, only such
          ----------------                                                     
business as is specified in the notice of such special meeting given by or at
the direction of the person or persons calling such meeting in accordance with
Section 2 of this Article II shall come before such meeting.

SECTION 8.  Voting

     Except as otherwise provided in the Certificate of Incorporation, each
stockholder shall, at each meeting of the stockholders, be entitled to one vote
in person or by proxy for each share of stock of the Corporation held by him and
registered in his name on the books of the Corporation:

     (a)  on the date fixed pursuant to the provisions of Section 5 of Article
VIII of these By-Laws as the record date for the determination of stockholders
who shall be entitled to receive notice of and to vote at such meeting, or

     (b)  if no record date shall have been so fixed, then at the close of
business on the day next preceding the day on which notice of the meeting shall
be given.

Shares of its own stock belonging to the Corporation or to another corporation,
if a majority of the shares entitled to vote in the election of 
<PAGE>
 
directors of such other corporation is held by the Corporation, shall neither
be entitled to vote nor considered as issued and outstanding for the purposes
of determining whether a quorum exists. Any vote of stock of the Corporation
may be given at any meeting of the stockholders by the stockholders entitled
thereto in person or by proxy appointed by an instrument in writing delivered
to the Secretary or an Assistant Secretary of the Corporation or the secretary
of the meeting. The attendance at any meeting of a stockholder who may
theretofore have given a proxy shall not have the effect of revoking the same
unless he shall in writing so notify the secretary of the meeting prior to the
voting of the proxy. At all meetings of the stockholders all matters, except
as otherwise provided in the Certificate of Incorporation, these By-Laws or by
law, shall be decided by the vote of a majority of the votes cast by
stockholders present in person or by proxy and entitled to vote thereat, a
quorum being present. Except as otherwise expressly required by law, the vote
at any meeting of the stockholders on any question need not be by ballot,
unless so directed by the chairman of the meeting. On a vote by ballot each
ballot shall be signed by the stockholder voting, or by his proxy, if there be
such proxy, and shall state the number of shares voted.

                               Indemnification

SECTION 1.  Right to Indemnification

     The Corporation shall to the fullest extent permitted by applicable law as
then in effect indemnify any person (the "Indemnitee") who was or is involved in
any manner (including, without limitation, as a party or a witness) or is
threatened to be made so involved in any threatened, pending or completed
investigation, claim, action, suit or proceeding, whether civil, criminal,
administrative or investigative (including without limitation, any action, suit
or proceeding by or in the right of the Corporation to procure a judgment in its
favor) (a "Proceeding") by reason of the fact that he is or was a director,
officer, employee or agent of the Corporation, or is or wall serving at 
<PAGE>
 
the request of the Corporation as a director, officer or employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
(including, without limitation, any employee benefit plan) against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
proceeding. Such indemnification shall be a contract right and shall include
the right to receive payment in advance of any expenses incurred by the
Indemnitee in connection with such proceeding, consistent with the provisions
of applicable law as then in effect.

SECTION 2.  Insurance, Contracts and Funding

     The Corporation may purchase and maintain insurance to protect itself and
any Indemnitee against any expenses, judgments, fines and amounts paid in
settlement as specified in Section I of this Article XI or incurred by any
Indemnitee in connection with any proceeding referred to in Section 1 of this
Article XI, to the fullest extent permitted by applicable law as then in effect.
The Corporation may enter into contracts with any director, officer, employee or
agent of the Corporation in furtherance of the provisions of this Article XI and
may create a trust fund, grant a security interest or use other means
(including, without limitation, a letter of credit) to ensure the payment of
such amounts as may be necessary to effect indemnification as provided in this
Article XI.

SECTION 3.  Indemnification; Not Exclusive Right

     The right of indemnification provided in this Article XI shall not be
exclusive of any other rights to which those seeking indemnification may
otherwise be entitled, and the provisions of this Article XI shall inure to the
benefit of the heirs and legal representatives of any person entitled to
indemnity under this Article XI and shall be applicable to Proceedings commenced
or continuing after the adoption of this Article XI, whether arising from acts
or omissions occurring before or after such adoption.

SECTION 4.  Advancement of Expenses; Procedures; Presumptions and
            Effect of Certain Proceedings; Remedies

     In furtherance, but not in limitation of the foregoing provisions, the
following procedures, presumptions and remedies shall apply with respect to
advancement of expenses and the right to indemnification under this Article XI:

     (a)  Advancement of Expenses.  All reasonable expenses incurred by or on
          -----------------------                                            
behalf of the Indemnitee in connection with any Proceeding shall be advanced to
the Indemnitee by the Corporation within 20 days after the receipt by the
Corporation of a statement or statements from the indemnitee 
<PAGE>
 
requesting such advance or advances from time to time, whether prior to or
after final disposition of such Proceeding. Such statement or statements shall
reasonably evidence the expenses incurred by the Indemnitee and, if required
by law at the time of such advance, shall include or be accompanied by an
undertaking by or on behalf of the Indemnitee to repay the amounts advanced if
it should ultimately be determined that the Indemnitee is not entitled to be
indemnified against such expenses pursuant to this Article XI.

     (b)  Procedure for Determination of Entitlement to Indemnification.
          ------------------------------------------------------------- 

          (i)     To obtain indemnification under this Article XI, an Indemnitee
          shall submit to the Secretary of the Corporation a written request,
          including such documentation and information as is reasonably
          available to the Indemnitee and reasonably necessary to determine
          whether and to what extent the Indemnitee is entitled to
          indemnification (the "Supporting Documentation").  The determination
          of the Indemnity's entitlement to indemnification shall be made not
          later than 60 days after receipt by the Corporation of the written
          request for indemnification together with the Supporting
          Documentation.  The Secretary of the Corporation shall, promptly upon
          receipt of such a request for indemnification, advise the Board of
          Directors in writing that the Indemnitee has requested
          indemnification.

          (ii)    The Indemnity's entitlement to indemnification under this 
          Article XI shall be determined in one of the following ways: (A) by
          a majority vote of the Disinterested Directors (as hereinafter
          defined), if they constitute a quorum of the Board of Directors; (B)
          by a written opinion of Independent Counsel (as hereinafter defined)
          if (x) a Change of Control (as hereinafter defined) shall have
          occurred and the Indemnitee so requests or (y) a quorum of the Board
          of Directors consisting of Disinterested Directors is not obtainable
          or, even if obtainable, a majority of such Disinterested Directors
          so directs; (C) by the stockholders of the Corporation (but only if
          a majority of the Disinterested Directors, if they constitute a
          quorum of the Board of Directors, presents the issue of entitlement
          to indemnification to the stockholders for their determination); or
          (D) as provided in Section 4(c).

          (iii)    In the event the determination of entitlement to 
          indemnification is to be made by Independent Counsel pursuant to
          Section 4(b)(ii), a majority of the Disinterested Directors shall
          select the Independent Counsel, but only an Independent Counsel to
          which the Indemnitee does not reasonably object; provided, however,
          that if a Change of Control shall have 
<PAGE>
 
          occurred, the Indemnitee shall select such Independent Counsel, but
          only an Independent Counsel to which the Board of Directors does not
          reasonably object.

     (c)  Presumptions and Effect of Certain Proceedings.  Except as otherwise
          ----------------------------------------------                      
expressly provided in this Article XI, if a Change of Control shall have
occurred, the Indemnitee shall be presumed to be entitled to indemnification
under this Article XI upon submission of a request for indemnification together
with the Supporting Documentation in accordance with Section 4(b)(i), and
thereafter the Corporation shall have the burden of proof to overcome that
presumption in reaching a contrary determination.  In any event, if the person
or persons empowered under Section 4(b) to determine entitlement to
indemnification shall not have been appointed or shall not have made a
determination within 60 days after receipt by the Corporation of the request
therefor, together with the Supporting Documentation, the Indemnitee shall be
deemed to be entitled to indemnification and the Indemnitee shall be entitled to
such indemnification unless (A)  the Indemnitee misrepresented or failed to
disclose a material fact in making the request for indemnification or in the
Supporting Documentation or (B)  such indemnification is prohibited by law.  The
termination of any Proceeding described in Section 1, or of any claim, issue or
matter therein, by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not, of itself, adversely affect the
---- ----------                                                              
right of the Indemnitee to indemnification or create a presumption that the
Indemnitee did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the Corporation or,
with respect to any criminal Proceeding, that the Indemnitee had reasonable
cause to believe that his conduct was unlawful.

     (d)  Remedies of Indemnitee.
          ---------------------- 

          (i)    In the event that a determination is made pursuant to 
          Section 4(b) that the Indemnitee is not entitled to indemnification
          under this Article XI, (A) the Indemnitee shall be entitled to seek
          an adjudication of his entitlement to such indemnification either,
          at the Indemnity's sole option, in (x) an appropriate court of the
          State of Delaware or any other court of competent jurisdiction or
          (y) an arbitration to be conducted by a single arbitrator pursuant
          to the rules of the American Arbitration Association; (B) any such
          judicial proceeding or arbitration shall be de novo and the
                                                      -------        
          Indemnitee shall not be prejudiced by reason of such adverse
          determination; and (C) if a Change of Control shall have occurred,
          in any such judicial proceeding or arbitration, the Corporation
          shall have the burden of proving that the Indemnitee is not entitled
          to indemnification under this Article XI.
<PAGE>
 
          (ii)    If a determination shall have been made or deemed to have been
          made, pursuant to Section 4(b) or 4(c), that the Indemnitee is
          entitled to indemnification, the Corporation shall be obligated to
          pay the amounts constituting such indemnification within five days
          after such determination has been made or deemed to have been made
          and shall be conclusively bound by such determination unless (A) the
          Indemnitee misrepresented or failed to disclose a material fact in
          making the request for indemnification or in the Supporting
          Documentation or (B) such indemnification is prohibited by law. In
          the event that (C) advancement of expenses is not timely made
          pursuant to Section 4(a) or (D) payment of indemnification is not
          made within five days after a determination of entitlement to
          indemnification has been made or deemed to have been made pursuant
          to Section 4(b) or 4(c), the Indemnitee shall be entitled to seek
          judicial enforcement of the Corporation's obligation to pay to the
          Indemnitee such advancement of expenses or indemnification.
          Notwithstanding the foregoing, the Corporation may bring an action,
          in an appropriate court in the State of Delaware or any other court
          of competent jurisdiction, contesting the right of the Indemnitee to
          receive indemnification hereunder due to the occurrence of an event
          described in subclause (A) or (B) of this clause (ii) (a
          "Disqualifying Event"); provided, however, that in any such action
          the Corporation shall have the burden of proving the occurrence of
          such Disqualifying Event.

          (iii)    The Corporation shall be precluded from asserting in any 
          judicial proceeding or arbitration commenced pursuant to this
          Section 4(d) that the procedures and presumptions of this Article XI
          are not valid, binding and enforceable and shall stipulate in any
          such court or before any such arbitrator that the Corporation is
          bound by all the provisions of this Article XI.

          (iv)    In the event that the Indemnitee, pursuant to this Section 
          4(d), seeks a judicial adjudication of or an award in arbitration to
          enforce his rights under, or to recover damages for breach of, this
          Article XI, the Indemnitee shall be entitled to recover from the
          Corporation, and shall be indemnified by the Corporation against,
          any expenses actually and reasonably incurred by him if the
          Indemnitee prevails in such judicial adjudication or arbitration. If
          it shall be determined in such judicial adjudication or arbitration
          that the Indemnitee is entitled to receive part but not all of the
          indemnification or advancement of expenses sought, the expenses
          incurred by the Indemnitee in 
<PAGE>
 
          connection with such judicial adjudication or arbitration shall be
          prorated accordingly.

                                    OMITTED

5.  ADDITIONAL RENT.
    ----------------

     a.   In addition to the Rent, Tenant shall pay to Landlord that percent of
          the total cost of the following items ("Adjustments") as the total
          floor area of the Premises bears to the total floor area of the
          Building as of the first day of each calendar month.

               (i) All real estate taxes and insurance premiums.  Said Real
          estate taxes shall include all real estate taxes and assessments that
          are levied upon or assessed against the Premises, including any taxes
          which may be levied on rents.  Said insurance premiums shall include
          all insurance premiums for fire, extended coverage, public liability,
          and other insurance which Landlord deems necessary.  If any tenant(s)
          in the Building pay taxes directly to any taxing authority or carry
          their own insurance, as may be provided in their Leases, the square
          footage of their Leased Premises shall not be included as part of the
          floor area of the Building for purposes of calculating Tenant's share
          of Adjustments:

               (ii) All costs to maintain, repair, replace, supervise, insure
          (including provision of public liability insurance) and administer
          common areas, parking lots, landscaping, sidewalks, driveways, roof
          covering, downspouts and gutters, the structural portions of the roof,
          foundations and exterior walls of the Building, and other areas used
          in common by the tenants or occupants of the Building.  Nothing in the
          foregoing sentence shall be construed to make Tenant liable for
          capital improvements not reasonably required for use or occupancy by
          Tenant.  The cost of any capital improvement made during the term of
          this Lease shall be amortized over the life of such improvement.
          Tenant shall not be required to pay for the costs to repair or replace
          any roof covering or the structural portions of the roof, foundations
          and exterior walls of the building should such maintenance, repair, or
          replacement occur during the first 24 months of the term of this
          Lease. Tenant shall be responsible for its share of the amortized cost
          of any capital improvement made and implemented thereafter and only
          for the remainder of the term of the Lease and any option periods,
          unless Tenant vacates the Premises during the said 24 month period.

               (iii)  Any parking charges or other costs levied, assessed or
          imposed by, or at the direction of, or resulting from statutes or
          regulations, or interpretations thereof, promulgated by any
          governmental authority or insurer in connection with the use or
          occupancy of the Premises or the common areas of the Building.

               (iv) Management fees for the operation of the Building not to
          exceed, however, any annual sum equal to four (4%) percent of the
          total annual fixed rent for the Building.
<PAGE>
 
     b.   Upon commencement of this Lease, Landlord shall submit to Tenant an
          estimate of monthly Adjustments for the period between such
          commencement date and the following July 1 and Tenant shall pay these
          estimated Adjustments on a monthly basis concurrently with the payment
          of the Rent. Tenant shall continue to make such monthly payments until
          notified by Landlord of a change therein.  By September 1 of each
          year, Landlord shall provide to Tenant a statement showing the total
          Adjustments for the prior calendar year and Tenant's allocable share
          thereof, prorated from the commencement date of this Lease during the
          first year. If the total monthly payments which Tenant has made for
          the prior calendar year (or portion thereof during which the Lease was
          in effect) is less than the Tenant's actual share of such Adjustments,
          then Tenant shall pay the difference in a lump sum and ten (10) days
          after receipt of such statement from Landlord. Any overpayment by
          Tenant shall be credited towards the Adjustments next due.  The actual
          Adjustments for the prior year shall be used for purposes of
          calculating the estimated monthly Adjustments for the current year
          with actual determination of such Adjustments occurring after the end
          of each calendar year, except that in any year in which resurfacing of
          the common parking area or major roof repairs are planned, Landlord
          may include the estimated cost of such work in the estimated monthly
          Adjustments.  Even though the term of this Lease has expired and
          Tenant has vacated the Premises, when the final determination is made
          of Adjustments for the year in which this Lease terminates, Tenant
          shall immediately pay any increase over the estimated Adjustment
          previously paid and, conversely, any overpayment shall be immediately
          returned by Landlord to Tenant.  Failure of Landlord to submit
          statements in a timely manner as called for herein shall be deemed a
          waiver of Tenant's obligation to pay Adjustments as herein provided.
          Upon Tenant's request, Landlord shall make available to Tenant copies
          of all invoices received by Landlord in connection with any costs
          incurred by Landlord which is subject to payment by Tenant under the
          provisions of this Article, and copies of the contracts between
          Landlord and those used by Landlord to perform any services which are
          subject to payment by Tenant under the provisions of this Article.

          Upon Tenant's request, Landlord shall make available to Tenant copies
          of all invoices received by Landlord in connection with any costs
          incurred by Landlord which is subject to payment by Tenant under the
          provisions of this Article, and copies of the contracts between
          Landlord and those used by Landlord to perform any services which are
          subject to payment by Tenant under the provisions of this Article.

6.   PERSONAL PROPERTY TAXES. Tenant shall pay, or cause to be paid, before
     -----------------------                                               
delinquency any and all taxes levied or assessed and which become payable during
<PAGE>
 
the term hereof upon all Tenant's Leasehold improvements, equipment, furniture,
fixtures, and any other personal property located on the Premises.  In the event
any or all of the Tenant's Leasehold improvements, equipment, furniture,
fixtures and other personal property shall be assessed and taxed with the real
property, Tenant shall pay to Landlord its share of such taxes within ten (10)
days after delivery to Tenant by Landlord of a statement in writing setting
forth the amount such tax is applicable to Tenant's property.

7.   UTILITY BILLS. Tenant shall promptly pay all water, sewer, gas,
     --------------                                                 
electricity, fuel, phone, light, heat, electric power and other utility bills
from the Premises.  If Tenant does not pay these bills, Landlord may pay them
and such payment shall be added to the Rent.

8.   LATE CHARGES.  If any Rent or other sums due from Tenant is not received by
     ------------                                                               
Landlord or Landlord's designated agent within ten (10) days after its due date,
then Tenant shall pay to Landlord a late charge equal to the maximum amount
permitted by law (and in the absence of any governing law, six percent (6%) of
such overdue amount), plus reasonable attorneys' fees incurred by Landlord due
hereunder. The parties hereby agree that such late charges represent a fair and
reasonable estimate of the cost that Landlord will incur by reason of Tenant's
late payment.  Landlord's acceptance of such late charges shall not constitute a
waiver of Tenant's default with respect to such overdue amount or stop Landlord
from exercising any of the other rights and remedies granted hereunder.

9.   SECURITY DEPOSIT.  Concurrently with Tenant's execution of this Lease,
     ----------------                                                      
Tenant has deposited with Landlord $38,000.00. Said sum shall be held by
Landlord as security for the faithful performance by Tenant of all the terms,
covenants, and conditions of this Lease to be kept and performed by Tenant
during the term hereof.  If Tenant defaults with respect to any provisions of
this Lease, including, but not limited to, the provisions relating to the
payment of Rent, Landlord may (but shall not be required to) use, apply or
retain all or any part of this security deposit for the payment of any Rent or
any other sum in default, or for the payment of any amount which Landlord may
spend or become obligated to spend by reason of Tenant's default, or to
compensate Landlord for any other loss or damage which Landlord may suffer by
reason of Tenant's default. If any portion of said security deposit is so used
or applied, Tenant shall, within ten (10) days after written demand therefor,
deposit cash with Landlord in any amount sufficient to restore the security
deposit to its original amount and Tenant's failure to do so shall be a default
under this Lease.  Landlord shall not be required to keep this security deposit
separate from its other funds, and (unless otherwise required by law) tenant
shall not be entitled to interest of such deposit. If Tenant shall fully and
faithfully perform every provision of this Lease to be performed by it, the
security deposit or any balance thereof shall be returned to Tenant (or, at
Landlord's option, to the last assignee of Tenant's interest hereunder) within
ten (10) days following expiration of this Lease term.  In the event of
termination of Landlord's interest in this Lease, Landlord shall transfer said
deposit to Landlord's successor in interest.

10.  USE OF PREMISES.

     a.   The Premises shall be used for office, R&D, light assembly and
          warehousing of personal computers to be used for the medical industry.
          Tenant shall not create any nuisance or trespass or vitiate the
          insurance or increase the rate of insurance of the Premises or the
          building.  Tenant agrees not to overload the floors of the Premises or
          of the building.  Tenant agrees not to use the Premises for any
          purpose or business which is illegal, noxious, offensive because of
          emission of noise, creates smoke, dust, or odors or which could damage
          the Building or the Lands environmentally or otherwise or be a
          nuisance or menace to or interfere with any other tenant or the
          public.  The floor load of the building is 200 lbs. per square inch.

     b.   Simultaneously herewith, Tenant shall furnish Landlord with all
          Standard Industrial Classification numbers as issued by the United
          States, the State of New Jersey or any other governmental authority
          ("SIC"), which relates to the business of the Tenant and the uses and
          purposes for which the Premises shall be utilized.  Tenant's SIC
          number is 3841.

11.  ABANDONMENT OF PREMISES.   Tenant agrees not to vacate the Premises during
     ------------------------                                                  
the term of this Lease unless rent and common area charges continue and agrees
to use said Premises for the purposes stated above and only for such purpose.

12.  DESTRUCTION AND DAMAGE.
     ---------------------- 

     a.   If the Building is damaged by fire or other perils covered by extended
          coverage insurance Landlord shall, at  Landlord's option:

          (i) In the event of total destruction of the Building, elect either to
          promptly commence repair and restoration of the Building and prosecute
          the same diligently to completion, in which event this Lease shall
          remain in full force and effect; or not to repair or restore said
          Building, in which event this Lease shall terminate. In either case,
          Landlord shall give Tenant written notice of its intention within
          sixty (60) days after the occurrence of such destruction.  If Landlord
          elects not to restore the building, this Lease shall be deemed to have
          terminated as of the date of such total destruction.

          (ii) In the event of a partial destruction of the Building to an
          extent not exceeding twenty-five percent (25%) of the full insurable
          value thereof and if the damage thereto is such that the Building may
          be repaired or restored within ninety (90) days from the date of such
          destruction and Landlord will receive insurance proceeds sufficient to
          cover the cost of such repairs, commence and proceed diligently with
          the work or repair and restoration, in which event the Lease shall
          continue in full force and effect; or if such repair and restoration
          requires longer than ninety (90) days or the cost thereof exceeds
<PAGE>
 
          twenty-five percent (25%) of the full insurable value thereof or if
          said insurance proceeds will not be sufficient to cover such costs,
          Landlord may elect either to so report and restore, in which event the
          Lease shall continue in full force and effect, or not repair,
          reconstruct or restore, in which event the lease shall terminate.  In
          either case, Landlord shall give written notice to Tenant of its
          intention within ninety (90) days after the destruction occurs.  If
          Landlord elects not to restore the Building, this Lease shall be
          deemed to have terminated as of the date of such partial destruction.

          b.  Upon termination of this Lease under any of the provisions of this
          Article, the parties shall be released thereby without further
          obligation to the other from the date of the damage or destruction,
          except for items which have theretofore accrued and are then unpaid,
          and except for those items which by their own nature survive the
          termination of the Lease.

          c.  In the event of repair and restoration as herein provided, the
          Rent shall be abated proportionately in the ratio which the Tenant's
          use of the Premises is impaired during the period of such repair,
          reconstruction or restoration.  Tenant shall not be entitled to any
          compensation or damages from loss of use of the whole or any part of
          said Premises and/or any inconvenience or annoyance occasioned by such
          damage, repair, reconstruction or restoration.

          d.  Landlord and Tenant shall not be released from any of their
          obligations under this Lease except to the extent and upon the
          conditions expressly stated in this Article. Notwithstanding anything
          to the contrary contained in this  Article, if Landlord has elected to
          repair and restore the Premises and is thereafter delayed or prevented
          from repairing and restoring said Premises within 120 days after the
          occurrence of such damage or destruction by reason of acts of God,
          war, governmental restrictions, inability to procure the necessary
          labor or materials, or other cause beyond the control of Landlord,
          Landlord shall be relieved of its obligation to make such repairs and,
          Tenant shall be released from its obligations under this Lease as of
          the end of said 120 day period.

          e.  If damage to the Building or the Premises is due to any cause
          other than fire or other peril covered by extended coverage insurance,
          Landlord or Tenant may elect to terminate this Lease immediately.

          f.  If Landlord is obligated to or elects to repair or restore as
          herein provided, Landlord shall repair or restore only those portions
          of said Building and Premises which were originally provided at
          Landlord's expense, and the repair and restoration of areas or items
          not provided at Landlord's expense shall be the obligation of Tenant.
<PAGE>
 
          g.  Notwithstanding anything to the contrary contained in this
          Article, Landlord shall not have any obligation to repair or restore
          the Premises or the Building during the last twelve (12) months of
          this Lease or any extension thereof. In such event, Tenant shall have
          the right to terminate this Lease immediately.

13.  CONDEMNATION.  If twenty-five percent (25%) or more of the Premises is
     -------------                                                         
taken for any public or quasi-public purpose by any lawful governmental power or
authority, by exercise or the right of appropriation, reverse condemnation,
condemnation or eminent domain or sold to prevent such taking, the Tenant or the
Landlord may at its option terminate this Lease as of the effective date
thereof.  Tenant shall not because of such taking assert any claim against the
Landlord or the taking authority for any compensation because of such taking,
and Landlord shall be entitled to receive the entire amount of any award without
deduction for any estate or interest of Tenant.  If less than twenty-five
percent (25%) of the Premises is taken, Landlord or Tenant at its option may
terminate this Lease.  If Landlord or Tenant do not so elect, Landlord shall
promptly proceed to restore the Premises to substantially their same condition
prior to such partial taking, allowing for the reasonable effects of such
taking, and a proportionate allowance shall be made to Tenant for the Rent and
Additional Rent corresponding to the time during which, and to the part of the
Premises of which, Tenant is deprived on account of such taking and restoration.

14.  INDEMNIFICATION.  Tenant agrees, as its sole cost and expense, to
     ----------------                                                 
indemnify and save Landlord harmless from and against any and all claims,
actions, demands and suits, for, in connection with, or resulting from, any
accident, injury or damage whatsoever caused to any person or property arising,
directly or indirectly, in whole or in part, out of the business conducted in or
the use of the Premises, or occurring in, on or about the Premises or any part
thereof, or arising, directly or indirectly, in whole or in part, from any act
of omission of Tenant or any concessionaire of subtenant or their respective
licensees, servants, agents, employees or contractors, or arising out of the
breach or default by Tenant or any term, provisions, covenant or condition
herein contained, and from and against any and all losses, costs, expenses,
judgments and liabilities incurred in connection with any claim, action, demand,
suit or other proceeding brought thereof, except for any loss or damage caused
by negligence of the Landlord, its employees and agents.  Said indemnity shall
include defending or resisting and proceeding by attorneys reasonably
satisfactory to Landlord.

     Landlord agrees, at its sole cost and expense, to indemnify and save
Tenant harmless from and against any and all claims, actions, demands, and suits
for, in connection with, or resulting from design defects in the Premises or any
accident, injury, or damage whatsoever caused to any person or property arising,
directly or indirectly, in whole or in part from any act or omission of Landlord
or any of their respective licensees, servants, agents, employees, or
contractors, or arising out of the breach or default by Landlord of any term,
provisions, covenant or condition herein contained, and from and against any and
all losses, costs, expenses, judgments and liabilities incurred in connection
<PAGE>
 
with any claim, action, demand, suit or other proceeding brought thereof, except

15.  LIABILITY INSURANCE.  Tenant shall, at Tenant's expense, obtain and
     --------------------                                               
keep in force during the term of this Lease policies of comprehensive public

and in the amount of not less than Three Million Dollars ($3,000,000) for injury
or death of more than one person in any one accident or occurrence.  Such
insurance shall further insure Landlord and Tenant against liability for
property damage of at least Three Million Dollars ($3,000,000).  The limit of
any such insurance shall not limit the liability of the Tenant hereunder.
Tenant may provide this insurance under a blanket policy, provided that said
insurance shall have an additional insured lessor endorsement attached thereto.
If Tenant fails to procure and maintain said insurance, Landlord may, but shall
not be required to, procure and maintain same, but at the expense of Tenant.
Insurance required hereunder shall be in companies rated A:XIII or better in
"Best Key Rating Guide".  Tenant shall deliver to Landlord copies of
certificates of insurance evidencing the liability insurance required herein.

excess of coverage which Landlord may carry and shall be written with an
insurance carrier satisfactory to Landlord.

16.  FIRE INSURANCE - FIXTURES AND EQUIPMENT.  Tenant shall maintain in
     ----------------------------------------                          
full force and effect on all of its fixtures and equipment on the Premises a

coverage endorsement in amount or amounts equal to the full replacement cost of
such fixtures and equipment. During the term of this Lease the proceeds from any
such policy or policies of insurance shall be used for the repair or replacement
of the fixtures and equipment so insured.  Landlord shall have no interest in
the insurance upon Tenant's equipment and fixtures and will sign all documents
reasonably necessary or proper in connection with the settlement of any claim or
loss by Tenant.  Landlord will not carry insurance on Tenant's possessions.
Tenant shall furnish Landlord with a certificate evidencing such policy and
whenever required shall satisfy Landlord that such policy is in full force and
effect.

17.  REPAIRS BY LANDLORD.  Landlord agrees to keep in good repair the
     --------------------                                            
structural portions of the roof, foundations, and exterior walls of the Premises
(exclusive of all glass and all exterior doors) and underground utility and
sewer pipes outside the exterior walls of the Building, if any, except repairs
rendered necessary by the negligence of Tenant, its agents, customers, employees
or invitees.  Landlord gives to Tenant exclusive control of the Premises and
shall be under no obligation to inspect said Premises.  Tenant shall promptly
report in writing to Landlord any defective condition known to it which Landlord
is required to repair. All repairs shall commence promptly following the receipt
of the written report, and shall be implemented in a timely manner.
<PAGE>
 
18.  REPAIRS BY TENANT.  Tenant accepts the Premises in their present
     ------------------                                              
condition pursuant to the plan attached to this Lease. Tenant shall, throughout
the initial term of this Lease and all renewals thereof, at its expense, take
good care of the Premises and shall keep, repair, replace and maintain the
Premises in good order, condition and repair, reasonable wear and tear excepted,
and each and every part thereof (including, without limitation, painting and
decorating, and the repair, maintenance and replacement of any heating,
ventilating and air conditioning units or system), except only such matters that
are expressly stated herein to be within the landlord's obligation to maintain,
and shall not cause nor permit any dirt, debris or rubbish to be put, placed or
maintained on the sidewalks, driveways, parking lots, yards, entrances and
curbs, in, oh or adjacent to the Building. Tenant further agrees not to use the
Premises or permit the Premises to be used in any manner as to cause excessive
depreciation of or to the Building and improvements, and agrees not to cause nor
permit waste of or damage or nuisance to, in, or about the Premises of the
Building.

19.  NO ACCESS TO ROOF.  Tenant shall have no right to access to the roof
     ------------------                                                  
of the Premises or the Building and shall not install, repair, place or replace
any aerial, fan, air conditioner or other device on the roof of the Premises or
the Building without the prior written consent of Landlord.  Any aerial, fan,
air conditioner or device installed without such written consent shall be
subject to removal at Tenant's expense, without notice, at any time.  Landlord
shall repair at Tenant's expense, any damage to the Building or roof resulting
from the installation, repair, use, or replacement of any such air conditioner
or other device.

20.  ASSIGNMENT AND SUBLETTING.  Tenant shall not either voluntarily, or by
     --------------------------                                            
operation of law, assign, transfer, mortgage, pledge, hypothecate or encumber
this Lease or any interest therein, and shall not sublet the Premises or any
part thereof, or any right or privilege appurtenant thereto, or allow any other
person (the employees, agents, servants and invitees of Tenant excepted) to
occupy or use their Premises, or any portion thereof, without first obtaining
the written consent of Landlord, which consent shall not be unreasonably
withheld. Tenant can transfer its rights to this Lease to a related entity
provided Tenant owns in excess of 51% of the entity. When Tenant requests
Landlord's consent to such assignment or subletting, it shall notify Landlord in
writing of the name and address of the proposed assignee or subtenant and the
nature and character of the business of the proposed assignee or subtenant and
shall provide financial statements for the  proposed assignee or subtenant.
Landlord shall have the option (to be exercised within thirty (30) days from the
submission of Tenant's request) to cancel this Lease as of the commencement date
stated in the proposed subLease or assignment.  If Landlord shall not exercise
its option within the time set forth above, its consent to any proposed
assignment or subletting shall not be unreasonably withheld. If Landlord
approves an assignment or subletting as herein provided, Tenant shall pay to
Landlord, as Additional Rent, the difference, if any between Rent plus
assignment or subLease pursuant to the provisions of this Lease, and the Rent
and Additional Rent payable by the assignee or sublessee to Tenant.  A consent
to one assignment, subletting, occupation or use shall not be deemed to be a
consent to any other or subsequent assignment, subletting, occupation or use and
consent to any assignment or subletting shall in no way relieve Tenant of any
<PAGE>
 
liability under this Lease. Any assignment or subletting without landlord's
consent shall be void, and shall, at the option of the Landlord, constitute a
default under this Lease.   In the event that Landlord shall consent to a
subLease or assignment hereunder, Tenant shall pay Landlord's reasonable fees,
not to exceed one hundred dollars per transaction, incurred in connection with
processing of documents necessary to the giving of such consent.

21.  TENANT DEFAULT.  The occurrence of any one of the following events
     ---------------                                                   
shall constitute an event of default ("Default") on the part of Tenant:

     a.   The vacating of the Premises by Tenant without the payment of rent and
          additional rent during the remaining Lease term;

     b.   Failure to pay any installment of Rent or any other monies due and
          payable hereunder;

     c.   Default in the performance of any of Tenant's covenants, agreements or
          obligations hereunder, said Default  (except Default in the payment of
          any installment of Rent, or other monies) continuing for ten (10) days
          after written notice thereof from Landlord to Tenant.  If effort is
          made to cure default but such effort is not completed within the ten
          (10) days provided for above, then Tenant shall have an additional
          fifteen (15) days to cure same.

     d.   The filing of a voluntary petition in bankruptcy by Tenant, the filing
          of a voluntary petition for any arrangement, the filing of a petition,
          voluntary or involuntary, for reorganization, or the filing of an
          involuntary petition by Tenant's creditors, said involuntary petition
          remaining undischarged for a period of sixty (60) days; unless tenant
          continues to pay rent.

     e.   Receivership, attachment, or other judicial seizure of substantially 
          all of Tenant's assets on the Premises, such attachment or other 
          seizure remaining undismissed or undischarged for a period of sixty 
          (60) days after the levy thereof.

22.  LANDLORD'S REMEDIES.
     --------------------

     a.   Damages. In the event of any such Default by Tenant, Landlord shall
          use its best efforts to relet the Premises.  All costs of such
          reletting shall be borne by Tenant and shall include but not limited
          to restoration, brokerage fees, attorney's fees, and marketing of the
          Premises. In addition to any other remedies available to Landlord at
          law or in equity, Landlord shall have the immediate option to
          terminate this Lease and all rights of Tenant hereunder by giving
          written notice to such intention to terminate. In the event that
          Landlord shall elect to so terminate this Lease then Landlord may
          recover from Tenant:
<PAGE>
 
          i.   the worth at the time of award of any unpaid Rent which has been
               earned at the time of such termination; plus

          ii.  the worth at the time of award of the amount by which the unpaid
               Rent which would have been earned after termination until the end
               of the Lease term is less than any rental payments due from
               reletting the Premises for the balance of the Lease term; plus

          iii. such reasonable attorney's fees incurred by Landlord as a result
               of such Default, and costs in the event suit is filed by Landlord
               to enforce such remedy; and

          iv.  At Landlord's election, such other amount in addition to or in
               lieu of the foregoing as may be permitted from time to time by
               applicable law.  The term "Rent", as used in this Article 22,
               shall be deemed to be and to mean the monthly Rent, Additional
               Rent and all other sums required to be paid by Tenant pursuant to
               the terms of this Lease.

               maximum remedies under this Paragraph shall include unpaid rent,
               and additional rent, plus ten percent (10%) .

               As used in Subparagraphs i and ii above, the "worth at the time
               of award" is computed by allowing interest at the rate of the
               Federal Reserve Bank of New York at the time of award plus one
               percent (1%).

     b.   Re-entry.  In the event of any such default by Tenant, Landlord shall
          ---------                                                            
          also have the right, with or without terminating this Lease, to
          reenter the Premises and remove all persons and property from the
          Premises; such property may be removed and stored in a public
          warehouse or elsewhere at the cost of and for the account of Tenant.


     c.   Election. In the event Landlord shall elect to relet, then rentals
          ---------                                                         
          received by Landlord from such reletting the Premises shall be
          applied, first, to reasonable  attorney's fees incurred by Landlord as
          a result of such Default and costs in the event suit is filed by
          Landlord to enforce such remedies; second, to the payment of any
          indebtedness other than Rent due hereunder from Tenant to Landlord;
          third, to the payment of any cost of such reletting; fourth, to the
          payment of cost of any alterations and repairs to the Premises, to
          restore the Premises to the condition at the start of the Lease term
          or to the condition as approved by Landlord under the terms of Article
          24, reasonable wear and tear excluded; fifth, to the payment of Rent
          due and unpaid hereunder; and the residue, if any, shall be held by
          Landlord and applied in payment of future rent as the same may become
          due and payable hereunder.  Should that portion of such rentals
<PAGE>
 
          received from such reletting during any month, which is applied by the
          payment of Rent hereunder, be less than the Rent payable during the
          month by Tenant hereunder, then Tenant shall pay such deficiency to
          Landlord. Such deficiency shall be calculated and paid monthly. Tenant
          shall also pay to Landlord, as soon as ascertained, any costs and
          expenses incurred by Landlord in such reletting or in making such
          alterations and repairs not covered by the rentals received from such
          reletting.

     d.   Termination. No re-entry or taking of possession of the Premises by
          -----------                                                        
          Landlord pursuant to this Article shall be construed as an election to
          terminate this Lease unless a written notice of such intention is
          given to Tenant or unless the termination thereof is decreed by a
          court of competent jurisdiction.  Notwithstanding any reletting
          without termination of Landlord because of any Default by Tenant,
          Landlord may at any time after such reletting elect to terminate this
          Lease for any such Default.

23.  SUBORDINATION - ATTORNMENT.  Upon request of Landlord, Tenant will in
     ---------------------------                                          
writing subordinate its rights hereunder to the lien of any mortgage or deed of
trust now or hereafter in force against the  Premises, provided the holder of
such mortgage or deed of trust grants Tenant a non-disturbance agreement, and to
all advances made or hereafter to be made upon the security thereof.

In the event any proceedings are brought for foreclosure, or in the event of the
exercise of the power of sale under any mortgage or deed of trust made by the
Landlord covering the Premises, the Tenant shall attorn to the purchaser upon
any such foreclosure or sale and recognize such purchaser as the Landlord under
this Lease.

The provisions of this Article to the contrary notwithstanding, and so long as
Tenant is not in default hereunder, this Lease shall remain in full force and
effect for full term hereof.

24.  ALTERATIONS AND ADDITIONS - REMOVAL OF FIXTURES.
     ------------------------------------------------

     a.   Tenant shall not make or allow to be made any alterations, additions
          or improvements to or on the Premises or any part thereof in excess of
          $1,000.00 without first obtaining the consent of Landlord, which
          consent shall not be unreasonably withheld and any alterations,
          additions or improvements to or on said Premises, shall at once become
          a part of the realty and belong to the Landlord and shall be
          surrendered with the Premises. In the event any such work shall cost
          in excess of Ten Thousand ($10,000) Dollars, such work shall not be
          commenced until Tenant shall submit to the Landlord plans and
          specifications relating to any such repairs, alterations, additions or
          improvements, and all such work shall be performed in accordance with
          the provisions of this Lease.  Landlord shall not unreasonably
          withhold its consent to any such alterations, addition or improvement,
<PAGE>
 
          but shall have the right to determine if such work would reduce the
          value, size or general utility of the Building or any portion thereof,
          or whether such work maintains the architectural harmony of the
          Building.  Any approval by Landlord as aforesaid may be upon condition
          thereof and payment therefor, as  Landlord may reasonably require,
          including the furnishing of adequate security. In the event Landlord
          consents to the making of any alterations, additions or improvements
          to the Premises by Tenant, the same shall be made by Tenant at
          Tenant's sole cost and expense and subject to the provisions of
          Section 42 herein. Upon the expiration or sooner termination of the
          term hereof, Tenant shall, upon written demand by Landlord, given at
          least thirty (30) days after the end of the term, at Tenant's sole
          cost and expense, forthwith and with all due diligence, remove any
          alterations, additions, or improvements made by Tenant, designated by
          Landlord to be removed, and Tenant shall, forthwith and with all due
          diligence, at its sole cost and expense, restore the Premises to the
          condition at the start of the Lease, reasonable wear and tear
          excluded, and repair any damage to the Premises caused by such
          removal.  Tenant shall not be required to remove and/or restore any
          alterations, additions or improvements if Landlord has specifically
          excluded, in writing, any of Tenant's alterations, additions, or
          improvements from Tenant's restoration obligations.

     b.   Any work performed by Tenant, irrespective of cost, shall be subject
          to the Landlord's inspection and approval after completion to
          determine whether it  complies with the requirements of this Lease.
          The approval or consent of the Landlord shall not relieve Tenant of
          its obligation that all such repairs, alterations, improvements and/or
          additions be constructed and performed in a first-class good  and
          workmanlike manner and in accordance with all applicable governmental
          and fire underwriting requirements, nor constitute a waiver of any
          rights of Landlord if Tenant fails to perform its obligations.
          Tenant, at its sole cost and expense, shall procure all necessary
          governmental approvals, permits or certificates in connection with all
          work performed by Tenant in, on or at the Premises and shall deliver
          the original of all such approvals, permits or certificates to the
          Landlord, to be retained by Landlord.

     c.   During the course of any and all repairs, alterations, additions or
          improvements which the Tenant shall either be required to perform or
          which the Tenant shall elect to perform, Tenant at its sole cost and
          expense, shall at all times obtain and maintain or cause to be
          obtained and maintained, workmen's compensation insurance and any
          other insurance which shall then be required by law, together with
          public liability insurance as set forth in Section 15 hereof, to
          insure against any additional hazards created in connection with the
          performance of any of the aforesaid work.  Prior to the commencement
          of any such work, Tenant shall deliver to Landlord copies of all
<PAGE>
 
          policies or certificates of insurance with respect to all policies
          required pursuant to this Section 24 (c).

25.  EXTERIOR SIGNS.  Tenant may not provide, install or maintain any exterior
     ---------------                                                          
signs on the roof or in the windows; nor shall the Tenant provide, install or
maintain any exterior signs on the facade or walls of the Building or on any

          on the part of the Landlord to make such inspection, repairs,
          additions or alterations except as otherwise herein provided. Any
          performance by Landlord hereunder shall not be deemed a waiver of

          at its sole cost and expense, promptly shall prepare and submit the
          required plan and financial assurances and promptly shall carry out

          accordance with Environmental Laws and DEPE. Landlord agrees to pay
          all costs and initiate all actions in accordance with this Paragraph

reflects the damage incurred by the Purchaser as a result of the Seller's
holdover.  Purchaser's sole remedy in the event of Seller's failure to vacate by
January 13, 1995, shall be the collection of the money specified in this Section
6.1.  Closing shall mean the consummation of this Agreement by the recording of

Dear Mr. Gillis:

  This letter is to confirm, as required by the Purchase Agreement dated
December   , 1994, (the "Purchase Agreement") by and between Advanced Technology
Laboratories, Inc. ("ATL"), Eldec Corporation, and N.C. Eldec, Inc.
(collectively "Eldec") that Crane Co. shall stand behind and guarantee the
performance of certain obligations of Eldec under the Purchase Agreement.
Specifically, Crane Co. shall indemnify, defend and hold ATL harmless on account
of: (1) either Eldec Corporation or N.C. Eldec, Inc. not being a corporation
duly organized and validly existing under the laws of Washington state; (2) the
Purchase Agreement and all documents executed and delivered, legal, valid, and
binding obligations sufficient to convey title (if they purport to do so) and in
compliance with all provisions of all agreements and judicial orders to which
Eldec Corporation or N.C. Eldec, Inc. is a party or to which Eldec Corporation
or N.C. Eldec, Inc. or all or any portion of the Property is subject.

  In addition, if at any time during the time periods set forth below, the
net worth of Eldec Corporation (as defined under normal customary accounting
standards and practices) is ever less than $60,000,000, or if Eldec Corporation
is reorganized, merged with Crane (or any other entity), or disposed of or
otherwise transferred by Crane Co., Crane Co. will stand behind the
indemnification obligations of Eldec contained in Section 16.1 of the Purchase
Agreement:

  (1) For 18 months following the date the transaction contemplated by the
      Purchase Agreement closes, as to indemnification for breaches of the
      representations contained in Sections 4(a) through 4(h) of the Purchase
      Agreement; and

  (2) For 24 months following the date the transaction contemplated by the
      Purchase Agreement closes, as to indemnification for breach of the
      representation contained in Section 4(i) of the Purchase Agreement.

                              Very truly yours,

                              CRANE CO.

          ----------------                                               
Indemnitor receives notice or otherwise becomes aware of (a) any environmental
problem or liability with respect to the Property or Other Property, (b) any
lien, action or notice resulting from the violation of any Environmental Laws or

harmless from and against any and all claims, demands, damages, losses, liens,
liabilities, penalties, fines, lawsuits and other proceedings and costs and
expenses (including attorneys' fees and disbursements, and architectural,
engineering and accounting costs and all repair and clean-up costs) which accrue
to or are made against or incurred by Lender, or are in any way connected with
(a) the inaccuracy of any of the certifications, representations or warranties
of Indemnitor contained in this Agreement, (b) any activities on the Property
during Indemnitor's ownership, possession or control of the Property which
directly or indirectly result in the Property or any Other Property being
contaminated with Hazardous Substances, or the Property being in violation of
any applicable Building Laws or Environmental Laws, or (c) the discovery and/or
cleanup of Hazardous Substances deposited or existing on the Property or any
Other Property, and (d) any breach by Indemnitor of any of its covenants or

acquires an interest in or rights to the Property by foreclosure or by a
conveyance in lieu of foreclosure of the deed of trust (the "Deed of Trust") or
any other instruments securing the Loan, or by any other means, the foregoing
indemnification obligation of Indemnitor shall survive such foreclosure or
conveyance in lieu of foreclosure or other acquisition of the Property.
Notwithstanding the preceding sentence, Indemnitor shall have no obligation to
defend, indemnify or hold Lender harmless from any claim, demand, damage, loss,
lien, liability, etc. arising from or out of the activities of Lender or its
agents on the Property on or after transfer of the Property to Lender pursuant

limitations on liability provided for in any document or instrument evidencing
or securing the Loan (collectively the "Loan Documents").  The certifications,
representations, warranties, covenants and agreements of Indemnitor set forth in
this Agreement (including without limitation the indemnity provided for in
Paragraph 7 above), (a) are separate and distinct obligations from Indemnitor's
obligations with respect to the Loan and under the Loan Documents, (b) are not
secured by the Deed of Trust or any other Loan Document, (c) shall not be
discharged or satisfied by foreclosure of the lien of the Deed of Trust or any
lien or security interest created by any other Loan Document, and (d) shall
continue in effect after any transfer of the Property, including without
limitation transfers pursuant to foreclosure proceedings (whether judicial or
nonjudicial), or by any conveyance in lieu of foreclosure.

evidencing the future advance or loan or other obligation specifically states
that it is secured by this Deed of Trust, or (ii) the advance, including costs
and expenses incurred by Beneficiary, is made pursuant to the Note, this Deed of
Trust or any other documents executed by Grantor evidencing, securing, or
relating to the Loan, and/or the Collateral, whether executed prior to,

hereafter collectively referred to as the "Loan Documents"), together with

this Deed of Trust is referenced in such transaction as a credit support
document.

Notwithstanding any of the foregoing, the Secured Obligations shall not include
the obligations of Grantor under any Certificate and Indemnity Agreement
Regarding Building Laws and Hazardous Substances now or hereafter executed by
Grantor (or any other person or entity) in connection with the loan evidenced by

                                   ARTICLE II
                                   ----------

     1.  ASSIGNMENT OF RENTS AND LEASES. Grantor hereby absolutely and
irrevocably assigns to Beneficiary all Grantor's interest in the Rents and
Leases.  The foregoing assignment is subject to the terms and conditions of any
separate assignment of the Leases and/or Rents, whenever executed, in favor of
Beneficiary and covering the Property.  Grantor warrants it has made no prior
assignment of the Rents or the Leases and will make no subsequent assignment
(other than to Beneficiary) without the prior written consent of Beneficiary.
At Beneficiary's request, Grantor shall execute and deliver to Beneficiary a
separate assignment of rents containing such terms and conditions as Beneficiary
may reasonably require.

          (a) Unless otherwise provided in any separate assignment of the Leases
and/or the Rents, and so long as Grantor is not in default under the Loan
Documents, Grantor may collect the Rents as the Rents become due.  Grantor shall
use the Rents to pay normal operating expenses for the Property and sums due and
payments required under the Loan Documents.  No Rents shall be collected for a
period subsequent to the current one month rental period and first or last
month's rent.  Grantor's right to collect the Rents shall not constitute
Beneficiary's consent to the use of cash collateral in any bankruptcy
proceeding.

                                       5
<PAGE>
 
          (b) If Grantor is in default under this Deed of Trust or any other
Loan Document, without notice to Grantor, Beneficiary or its agents, or a court
appointed receiver, may collect the Rents.  In doing so, Beneficiary may (i)
evict lessees for nonpayment of rent, (ii) terminate in any lawful manner any
tenancy or occupancy, (iii) lease the Property in the name of the then owner on
such terms as it may deem best, (iv) institute proceedings against any lessee
for past due rent, and (v) do all other acts and things as Beneficiary deems
necessary or desirable.  The Rents received shall be applied to payment of the
costs and expenses of collecting the Rents, including a reasonable fee to
Beneficiary, a receiver or an agent, operating expenses for the Property and any
sums due or payments required under the Loan Documents, in such order as
Beneficiary may determine.  Any excess shall be paid to Grantor, however,
Beneficiary may withhold from any excess a reasonable amount to pay sums
anticipated to become due which exceed the anticipated future Rents.
Beneficiary's failure to collect or discontinuing collection at any time shall
not in any manner affect the subsequent enforcement by Beneficiary of its rights
to collect the Rents.  The collection of the Rents by or for Beneficiary shall
not cure or waive any default under the Loan Documents.  Any Rents paid to
Beneficiary or a receiver shall be credited against the amount due from the
lessees under the Leases.  In the event any lessee under a Lease becomes the
subject of any proceeding under the Bankruptcy Code or any other federal, state
or local statute which provides for the possible termination or rejection of any
Lease assigned hereby, Grantor covenants and agrees that in the event any of the
Leases are so rejected, no damages settlement shall be made without the prior
written consent of Beneficiary; any check in payment of damages for rejection or
termination of any such Lease will be made payable both to the Grantor and
Beneficiary; and Grantor hereby assigns any such payment to Beneficiary and
further covenants and agrees that upon request of Beneficiary, it will duly
endorse to the order of Beneficiary any such check, the proceeds of which will
be applied to any portion of the indebtedness secured hereunder in such manner
as Beneficiary may elect.

          (c) Regardless of whether or not Beneficiary, in person or by agent,
takes actual possession of the Property or any part thereof, Beneficiary is not
and shall not be deemed to be:  (i) "a mortgagee in possession" for any purpose;
(ii) responsible for performing any of the obligations of the lessor under any
Lease; (iii) responsible for any waste committed by lessees or any other
parties, any dangerous or defective condition of the Property, or any negligence
in the management, upkeep, repair or control of the Property; or (iv) liable in
any manner for the Property or the use, occupancy, enjoyment or operation of all
or any part of it.  In exercising its rights under this Section 1 Beneficiary
shall be

                                       6
<PAGE>
 
liable only for the proper application of and accounting for the Rents collected
by Beneficiary or its agents.

     2.  LEASES. Grantor shall fully comply with all of the terms, conditions
and provisions of the Leases so that the same shall not become in default and do
all things necessary to preserve the Leases in force.  Unless otherwise agreed
in writing by Beneficiary, without Beneficiary's prior written consent, Grantor
will not enter into any Lease (i) for a term of three (3) years or more, or (ii)
containing an option or right to purchase all or any part of the Collateral in
favor of any lessee.  With respect to any Lease of the whole or any part of the
Property involving an initial term of three (3) years or more, Grantor shall
not, without the prior written consent of Beneficiary, (a) permit the assignment
or subletting of all or part of the lessee's rights under the Lease unless the
right to assign or sublet is expressly reserved by the lessee under the Lease,
(b) modify or amend the Lease for a lesser rental or term, or (c) accept
surrender of the Lease or terminate the Lease except in accordance with the
terms of the Lease providing for termination in the event of a default.  After a
default under the Note or any other Loan Document, any proceeds or damages
resulting from a lessee's default under any Lease, at Beneficiary's option,
shall be paid to Beneficiary and applied against sums owed under the Loan
Documents even though such sums may not be due and payable.  Except for real
estate taxes and assessments, without Beneficiary's prior written consent,
Grantor shall not permit any lien to be created against the Property which may
be or may become prior to any Lease.  If the Property is partially condemned or
suffers a casualty, Grantor shall promptly repair and restore the Property in
order to comply with the Leases.

                                  ARTICLE III
                                  -----------

     1.  NON-AGRICULTURAL USE. Grantor represents and warrants to Beneficiary
that neither the Property nor any other Collateral is used principally or
primarily for agricultural or farming purposes.

     2.  PERFORMANCE OF OBLIGATIONS. Grantor shall promptly and timely pay all
sums due pursuant to the Loan Documents, strictly comply with all the terms and
conditions of the Loan Documents, and perform each Secured Obligation in
accordance with its terms.

     3.  WARRANTY OF TITLE. Grantor warrants that it has good and marketable

interests, claims or defects of any kind prior or subordinate to the lien of
this Deed of Trust, except those listed in Beneficiary's title insurance policy
or approved by Beneficiary in writing (the "Exceptions") and real estate taxes
and assessments for the current year.  Grantor warrants the Exceptions and the
real estate taxes and assessments are not delinquent or in default, and Grantor
has the right to convey the Property to Trustee for the benefit of Beneficiary,
and the right to grant a security interest in the personal property Collateral.
Grantor will warrant and defend title to the Collateral and will defend the
validity and priority of the lien of this Deed of Trust and the security
interests granted herein against any claims or demands.

     4. PROHIBITED LIENS. 

          (a) Subject to Grantor's rights under subsection (b) below, Grantor
shall not permit any governmental or statutory liens (including taxes,
mechanic's or materialmen's liens) to be filed against the Collateral except for
real estate taxes and assessments not yet due and liens permitted by the Loan
Documents or approved by Beneficiary in writing.

          (b) Grantor will have the right to contest in good faith by
appropriate legal or administrative proceeding the validity of any prohibited
lien, encumbrance or charge so long as (i) no default exists under the Loan
Documents, (ii) with respect to any lien other than a mechanic's or
materialmen's lien, Grantor first deposits with Beneficiary a bond or other
security satisfactory to Beneficiary in the amount reasonably required by
Beneficiary; (iii) Grantor immediately commences its contest of such lien,
encumbrance or charge, applies to court for a show cause as provided for in RCW
60.04.221(9), as now or hereafter amended, and continuously pursues the contest
in good faith and with due diligence; (iv) foreclosure of the lien, encumbrance
or charge is stayed; and (v) Grantor pays any judgment rendered for the lien
claimant or other third party within ten (10) days after the entry of the
judgment.  If the contested item is a mechanic's or materialmen's lien, Grantor
will furnish Beneficiary with an endorsement to its title insurance policy which
insures the priority of this Deed of Trust over the lien being contested.
Grantor will discharge or elect to contest and post an appropriate bond or other
security within twenty (20) days of written demand by Beneficiary.

     5.  PAYMENT OF TAXES AND OTHER ENCUMBRANCES. Grantor shall pay the real
estate taxes and any assessments or ground rents prior to delinquency unless
otherwise provided for in the reserve account described in Section 15 below.
All other encumbrances, charges and liens affecting the Collateral, including
mortgages and deeds of trust, whether prior to or subordinate to the lien of
this Deed of

                                       8
<PAGE>
 
Trust, shall be paid when due and shall not be in default.  On request Grantor
shall furnish evidence of payment of these items.

     6.  MAINTENANCE--NO WASTE. Grantor shall protect and preserve the
Collateral and maintain it in good condition and repair.  Grantor shall do all
acts and take all precautions which, from the character and use of the
Collateral, are reasonable, proper or necessary to so maintain, protect and
preserve the Collateral.  Grantor shall not commit or permit any waste of the
Collateral.

     7.  ALTERATIONS, REMOVAL AND DEMOLITION. Unless otherwise agreed in
writing by Beneficiary, Grantor shall not alter, remove or demolish any of the
structural elements of the building or improvements on the Property without
Beneficiary's prior written consent.  Grantor shall not remove any fixture or
other item of property which is part of the Collateral without Beneficiary's
prior written consent unless the fixture or item of property is replaced by an
article of equal suitability, owned by Grantor free and clear of any lien or
security interest.

     8.  COMPLETION, REPAIR AND RESTORATION. Grantor shall promptly complete or
repair and restore in good workmanlike manner any building or improvement on the
Property which may be constructed or damaged or destroyed and shall pay all
costs incurred therefor.  With respect to alterations or construction subject to
Beneficiary's approval, prior to commencement of any construction Grantor shall
submit the plans and specifications for Beneficiary's approval and furnish
evidence of sufficient funds to complete the work.

     9.  COMPLIANCE WITH LAWS. Grantor shall comply with all laws, ordinances,
regulations, covenants, conditions, and restrictions affecting the Collateral,
as applicable, including, without limitation, all applicable requirements of the
Fair Housing Act of 1968 (as amended) and the Americans With Disabilities Act of
1990 (as the same may be amended from time to time), and shall not commit or
permit any act upon or concerning the Collateral in violation of any such laws,
ordinances, regulations, covenants, conditions, and restrictions, as applicable.
Grantor shall defend, indemnify and hold Beneficiary harmless from and against
all liability threatened against or suffered by Beneficiary by reason of a
breach by Grantor of the foregoing representations, warranties, covenants and
agreements.  The foregoing indemnity shall include the cost of all alterations
to the Collateral (including architectural, engineering, legal and accounting
costs), all fines, fees and penalties, and all legal and other expenses
(including attorneys' fees) incurred in connection with the Property being in
violation of any such laws, ordinances, regulations, covenants, conditions and
restrictions.  If

                                       9
<PAGE>
 
Beneficiary or its designee shall become the owner of or acquire an interest in
or rights to the Collateral by foreclosure or deed in lieu of foreclosure of
this Deed of Trust or by other means, the foregoing indemnification obligation
shall survive such foreclosure or deed in lieu of foreclosure or other
acquisition of the Collateral.  Notwithstanding the preceding sentence, Grantor
shall have no obligation to defend, indemnify or hold Beneficiary harmless from
any liability arising from or out of the activities of Beneficiary or its agents
with respect to the Collateral on or after the transfer of the Collateral to
Beneficiary pursuant to foreclosure proceedings or in lieu thereof.

     10.  IMPAIRMENT OF COLLATERAL. Grantor shall not, without Beneficiary's
prior written consent, change the general nature of the occupancy of the
Property, initiate, acquire or permit any change in any public or private
restrictions (including without limitation a zoning reclassification) limiting
the uses which may be made of the Collateral, or take or permit any action which
would impair the Collateral or Beneficiary's lien or security interest in the
Collateral.

     11.  INSPECTION OF COLLATERAL. Beneficiary and/or its representative may
inspect the Collateral at reasonable times after reasonable notice.

     12.  GRANTOR'S DEFENSE OF COLLATERAL. Grantor shall appear in and defend
any action or proceeding which may affect the Collateral or the rights or powers
of Beneficiary or Trustee under this Deed of Trust.

     13.  BENEFICIARY'S RIGHT TO PROTECT COLLATERAL. Beneficiary may commence,
appear in, and defend any action or proceeding which may affect the Collateral
or the rights or powers of Beneficiary or Trustee under this Deed of Trust.
Beneficiary may pay, purchase, contest or compromise any encumbrance, charge or
lien not listed as an Exception which in its judgment appears to be prior or
superior to the lien of this Deed of Trust.  If Grantor fails to make any
payment or do any act required under the Loan Documents, Beneficiary, without
any obligation to do so and without releasing Grantor from any obligations under
the Loan Documents, may make the payment or cause the act to be performed in
such manner and to such extent as Beneficiary may deem necessary to protect the
Collateral.  Beneficiary is authorized to enter upon the Property for such
purposes.  In exercising any of these powers Beneficiary may incur such
expenses, in its absolute discretion, it deems necessary.

     14.  HAZARDOUS SUBSTANCES. 

          (a) Grantor represents and warrants to Beneficiary, to the best of
Grantor's knowledge after due and diligent inquiry, no

                                       10
<PAGE>
 
hazardous or toxic waste or substances are being stored on the Property nor have
any such waste or substances been stored or used in, on, under, over or about
the Property prior to or during Grantor's ownership, possession or control of
the Property, other than the use or storage of hazardous or toxic waste or
substances generally used in the ordinary course of operating, maintaining or
developing properties such as the Property or in the ordinary course of
operating the business of Grantor (or any prior owner of all or part of the
Property), all of which Grantor covenants have (to its knowledge) and will be
used, stored and disposed of in accordance with all applicable federal, state
and local laws, regulations and ordinances.  Grantor shall provide written
notice to Beneficiary immediately upon Grantor becoming aware that the Property
is being or has been contaminated with hazardous or toxic waste or substances.
Grantor will not cause nor permit any activities on the Property which directly
or indirectly could result in the Property or any other property becoming
contaminated with hazardous or toxic waste or substances; provided the foregoing
shall not preclude Grantor from using or generating hazardous or toxic wastes or
other substances in the ordinary course of operating the business of Grantor on
the Property if such use is in accordance with commercially reasonable practices
and all applicable federal, state or local laws, regulations and ordinances.
For purposes of this Deed of Trust, the term "hazardous or toxic waste or
substances" means any chemical, substance or material classified or designated
as hazardous, toxic or radioactive, or similar term, and now or hereafter
regulated under any applicable federal, state or local statute, regulation,
ordinance or requirement, now or hereafter in effect, pertaining to
environmental protection, contamination or cleanup.

          (b) Grantor shall comply, at Grantor's expense, with all applicable
statutes, regulations and ordinances which apply to Grantor or the Collateral,
and with all orders, decrees or judgments of governmental authorities or courts
having jurisdiction which Grantor is bound by, relating to the use, collection,
storage, treatment, control, removal or cleanup of hazardous or toxic substances
in, on, under, over or about the Property or in, on, under, over or about any
adjacent property that becomes contaminated with hazardous or toxic substances
as a result of construction, operations or other activities on, or the
contamination of, the Property.  Beneficiary may, but is not obligated to, enter
upon the Property to inspect it for compliance and to take such actions and
incur such costs and expenses to effect such compliance as it deems advisable to
protect its interest as Beneficiary; and whether or not Grantor has actual
knowledge of the existence of hazardous or toxic substances in, on, under, over
or about the Property or any adjacent property as of the date hereof, Grantor
shall reimburse Beneficiary on demand for the full amount of all reasonable
costs and expenses incurred by

                                       11
<PAGE>
 
Beneficiary prior to Beneficiary acquiring title to the Property through
foreclosure or deed in lieu of foreclosure, in connection with such compliance
activities.

          (c) Grantor's obligations under this Section 14 are unconditional and
shall not be limited by a non-recourse or other limitations of liability
provided for in this Deed of Trust or any other Loan Document.


     15.  RESERVE ACCOUNT.

          (a) Subject to subsection (d) below, if Beneficiary so requires,
Grantor shall pay to Beneficiary monthly, together with and in addition to any
payments due under the Note, a sum, as estimated by Beneficiary, equal to the
ground rents, if any, the real estate taxes and assessments next due on the
Property and the premiums next due on insurance policies required under the Loan
Documents, less all sums already paid therefor, divided by the number of months
to elapse before two (2) months prior to the date when the ground rents, real
estate taxes, assessments and insurance premiums will become delinquent.  The
monthly reserve accounts payments and any other payments due under the Note
shall be paid in a single payment and applied by Beneficiary, at its option, in
the following order: (1) ground rents, real estate taxes, assessments and
insurance premiums, (2) expenditures made pursuant to the Loan Documents and
interest thereon, (3) interest on the Note, and (4) principal due on the Note.
Grantor shall promptly deliver to Beneficiary all bills and notices pertaining
to the ground rents, taxes, assessments and insurance premiums.

          (b) The reserve account is solely for the protection of Beneficiary.
Beneficiary shall have no responsibility except to credit properly the sums
actually received by it.  No interest will be paid on the funds in the reserve
account and Beneficiary shall have no obligation to deposit the funds in an
interest-bearing account.  Upon assignment of this Deed of Trust by Beneficiary,
any funds in the reserve account shall be turned over to the assignee and any
responsibility of Beneficiary with respect thereto shall terminate.  Each
transfer of the Property shall automatically transfer to the grantee all rights
of Grantor to any funds in the reserve account.

          (c) If the total of the payments to the reserve account exceeds the
amount of payments actually made by Beneficiary, plus such amounts as have been
reasonably accumulated in the reserve account toward payments to become due,
such excess may, at Beneficiary's election, be (1) credited by Beneficiary
against sums then due and payable under the Loan Documents, or (2) refunded to
Grantor as its name appears on the records of Beneficiary.  If, however, the
reserve account does not have sufficient funds to make

                                       12
<PAGE>
 
the payments when they become due, Grantor shall pay to Beneficiary the amount
necessary to make up the deficiency within fifteen (15) days after written
notice to Grantor.  If this Deed of Trust is foreclosed or if Beneficiary
otherwise acquires the Collateral, the Beneficiary shall, at the time of
commencement of the proceedings or at the time the Collateral is otherwise
acquired, apply the remaining funds in the reserve account, less such sums as
will become due during the pendency of the proceedings, against the sums due
under the Loan Documents and/or to make payments required under the Loan
Documents.

          (d) Unless required by the terms of Beneficiary's loan commitment or
any other Loan Document, Grantor shall not be required to pay monthly reserve
account payments so long as there has been no more than four (4) late payments
due under the Note throughout the term of the Loan and there is no other default
under the Loan and so long as Grantor remains in ownership of the Collateral,
provided receipted bills evidencing the payment of all taxes and/or assessments
and insurance premiums are exhibited to Beneficiary within fifteen (15) days
after Beneficiary's request therefor.  Upon any change in any of these
conditions, Beneficiary may, at its option then or thereafter exercised, require
the payment of reserves pursuant to this Section 15.

     16.  REPAYMENT OF BENEFICIARY'S EXPENDITURES. Grantor shall pay within ten
(10) days after written notice from Beneficiary all sums expended by Beneficiary
and all costs and expenses incurred by Beneficiary in taking any actions
pursuant to the Loan Documents including attorneys' fees, accountants' fees,
appraisal and inspection fees, and the costs for title reports.  If any laws or
regulations are passed subsequent to the date of this Deed of Trust which
require Beneficiary to incur out-of-pocket expenses in order to maintain,
modify, extend or foreclose this Deed of Trust, revise the terms of the Loan or
consent to an Accelerating Transfer (as defined below), Grantor shall reimburse
Beneficiary for such expenses within fifteen (15) days after written notice from
Beneficiary.  Expenditures by Beneficiary shall bear interest from the date of
such advance or expenditure at the default interest rate in the Note, shall
constitute advances made under this Deed of Trust and shall be secured by and
have the same priority as the lien of this Deed of Trust.  If Grantor fails to
pay any such expenditures, costs and expenses and interest thereon, Beneficiary
may, at its option, without foreclosing the lien of this Deed of Trust, commence
an independent action against Grantor for the recovery of the expenditures
and/or advance any undisbursed Loan proceeds to pay the expenditures.

     17.  ACCELERATING TRANSFERS. 

          (a) "Accelerating Transfer" means any sale, contract to sell,
conveyance, encumbrance, transfer of full possessory rights, or other transfer
of all or any material part of the Collateral or any interest in it, whether
voluntary, involuntary, by operation of law or otherwise and whether or not for
record or for consideration.  If Grantor is a corporation, "Accelerating
Transfer" also means any transfer or transfers of shares possessing, in the
aggregate, more than fifty percent (50%) of the voting power.  If Grantor is a
partnership, "Accelerating Transfer" also means withdrawal or removal of any
general partner, dissolution of the partnership under Washington law, or any
transfer or any transfers of, in the aggregate, more than fifty percent (50%) of
the partnership interests.  If Grantor is the majority owner of a business,
either through ownership of shares of a corporation or interest in a partnership
or otherwise, which occupies seventy-five percent (75%) or more of the
improvements on the Property, "Accelerating Transfer" also means any sale,
contract to sell, or other transfer of the business or substantial assets of the
business, other than in the ordinary course, or the failure of the business to
continue to occupy the Property.

          (b) Grantor acknowledges Beneficiary is taking actions in reliance on
the expertise, skill, experience and reliability of Grantor, and the obligations
secured hereby include material elements similar in nature to a personal service
contract or ownership interest.  In consideration of Beneficiary's reliance,
Grantor agrees that Grantor shall not make any Accelerating Transfer without
Beneficiary's prior written consent, which Beneficiary may withhold in its sole
discretion.  If Beneficiary consents, it may charge the Grantor a fee as
consideration for such consent and condition its consent on such changes to the
terms and conditions of the Note and other Loan Documents as Beneficiary may
require, including without limitation increasing the interest rate on the Note.
Grantor shall pay Beneficiary's actual costs incurred in making its decision to
consent to an Accelerating Transfer, including but not limited to the cost of
credit reports, an updated appraisal of the Property, an updated environmental
assessment and documentation.  If any Accelerating Transfer occurs without
Beneficiary's prior written consent, Beneficiary in its sole discretion may
declare an immediate default and all sums secured by this Deed of Trust to be
immediately due and payable, and Beneficiary may invoke any rights and remedies
provided herein.  This provision shall apply to each and every Accelerating
Transfer regardless of whether or not Beneficiary has consented or waived its
rights, whether by action or nonaction, in connection with any previous
Accelerating Transfer(s).

                                       14
<PAGE>
 
          (c) If all or any part of this Section 17 relevant to a particular
Accelerating Transfer is unenforceable according to the law in effect at the
time of the Accelerating Transfer, then Grantor shall reimburse Beneficiary for
its actual costs incurred in processing the Accelerating Transfer on its
records, including but not limited to the cost of modifications of Loan
Documents, an appraisal, and obtaining relevant credit and financial
information.

          (d) By the acceptance of this Deed of Trust, the Beneficiary agrees it
will, upon request of the Grantor, if no default exists under this Deed of Trust
and no event has occurred which through the passage of time, the giving of
notice or both, could constitute a default, join with the Grantor in requesting
the Trustee to partially reconvey a portion of the Property, consisting of
approximately 17 acres (including approximately 7.7 acres of wetlands) of
unimproved real property, if the following conditions are met:

             (1) Grantor delivers to Beneficiary evidence that (i) the partial
reconveyance will not have any adverse effect upon the priority position of the
remaining security as evidenced by the title insurance held by the Beneficiary,
and (ii) the remaining Property constitutes one or more "legal lots" under
applicable zoning and subdivision laws.

             (2) The Property shall have been short platted or otherwise
subdivided in accordance with regulations of the local government authority, and
Beneficiary must receive evidence of final short plat (or other subdivision)
approval from the government authority.  Any such short plat or subdivision
shall be subject to the reasonable approval of Beneficiary.

             (3) The release, in Beneficiary's reasonable opinion, will not
result in the loss by any other part of the Property of reasonable access to a
public street or the use of any necessary easements or utility services.

     18.  RELEASE OF PARTIES OR COLLATERAL. Without affecting the obligations
of any party under the Loan Documents and without affecting the lien of this
Deed of Trust and Beneficiary's security interest in the Collateral, Beneficiary
and/or Trustee may, without notice (a) release all or any Grantor and/or any
other party now or hereafter liable for any of the Secured Obligations
(including guarantors), (b) release all or any part of the Collateral, (c)
subordinate the lien of this Deed of Trust or Beneficiary's security interest in
the Collateral, (d) take and/or release any other security for or guarantees of
the Secured Obligations, (e) grant an extension of time for performance of the
Secured Obligations, (f) modify, waive, forbear, delay or fail to enforce any of
the Secured Obligations, (g) sell or otherwise realize on

                                       15
<PAGE>
 
any other security or guaranty prior to, contemporaneously with or subsequent to
a sale of all or any part of the Collateral, (h) make advances pursuant to the
Loan Documents including advances in excess of the Note amount, (i) consent to
the making of any map or plat of the Property, and (j) join in the grant of any
easement on the Property.  Any subordinate lienholder shall be subject to all
such releases, extensions or modifications without notice to or consent from the
subordinate lienholder.  Grantor shall pay any Trustee's, attorneys', title
insurance, recording, inspection or other fees or expenses incurred in
connection with release of Collateral, the making of a map, plat or the grant of
an easement.

                                   ARTICLE IV
                                   ----------

     1.  INSURANCE. 

          (a) Grantor shall maintain such insurance on the Collateral as may be
reasonably required from time to time by Beneficiary, with premiums prepaid,
providing replacement cost coverage and insuring against loss by fire and such
other risks covered by extended coverage insurance, and such other perils and
risks as Beneficiary may reasonably require from time to time, including
earthquake, loss of rents and business interruption.  Grantor also shall
maintain comprehensive general public liability insurance and if the Property is
located in a designated flood hazard area, flood insurance.  All insurance shall
be with companies reasonably satisfactory to Beneficiary and in such amounts and
with such coverages as Beneficiary may reasonably require from time to time,
with lender's loss payable clauses in favor of and in form reasonably
satisfactory to Beneficiary.  At least thirty (30) days prior to the expiration
of the term of any insurance policy, Grantor shall furnish Beneficiary with
written evidence of renewal or issuance of a satisfactory replacement policy.
If requested Grantor shall deliver copies of all polices to Beneficiary.  Each
policy of insurance shall provide Beneficiary with no less than forty-five (45)
days prior written notice of any cancellation, expiration, non-renewal or
modification.

          (b) In the event of foreclosure of this Deed of Trust all interest of
Grantor in any insurance policies pertaining to the Collateral and in any claims
against the policies and in any proceeds due under the policies shall pass to
Beneficiary.

          (c) If under the terms of any Lease the lessee is required to maintain
insurance of the type required by the Loan Documents and if the insurance is
maintained for the benefit of both the lessor and Beneficiary, Beneficiary will
accept such policies provided all of the requirements of Beneficiary and the
Loan Documents are met.  In the event the lessee fails to maintain

                                       16
<PAGE>
 
such insurance, Grantor shall promptly obtain such policies as are required by
the Loan Documents.

          (d) If Grantor fails to maintain any insurance required of it by
Beneficiary, or fails to pay any premiums with respect to such insurance,
Beneficiary may obtain such replacement insurance as it deems necessary or
desirable, or pay the necessary premium on behalf of Grantor, and any sums
expended by Beneficiary in so doing shall be added to the principal balance of
the Note and bear interest at the default interest rate set forth in the Note.

     2.  DAMAGES AND CONDEMNATION AND INSURANCE PROCEEDS.

          (a) Grantor hereby absolutely and irrevocably assigns to Beneficiary,
and authorizes the payor to pay to Beneficiary, the following claims, causes of
action, awards, payments and rights to payment:  (i) all awards of damages and
all other compensation payable directly or indirectly because of a condemnation,
proposed condemnation or taking for public or private use which affects all or
part of the Collateral or any interest in it; (ii) all other awards, claims and
causes of action, arising out of any warranty affecting all or any part of the
Collateral, or for damage or injury to or decrease in value of all or part of
the Collateral or any interest in it; (iii) all proceeds of any insurance
policies payable because of loss sustained to all or part of the Collateral up
to the amount of the indebtedness and obligations of Grantor under the Note and
the other Loan Documents; and (iv) all interest which may accrue on any of the
foregoing.

          (b) Grantor shall immediately notify Beneficiary in writing if: (i)
any damage occurs or any injury or loss is sustained in the amount of $25,000 or
more to all or part of the Collateral, or any action or proceeding relating to
any such damage, injury or loss is commenced; or (ii) any offer is made, or any
action or proceeding is commenced, which relates to any actual or proposed
condemnation or taking of all or part of the Collateral.  If Beneficiary chooses
to do so, it may in its own name appear in or prosecute any action or proceeding
to enforce any cause of action based on warranty, or for damage, injury or loss
to all or part of the Collateral, and if Grantor is in default under the Note or
any other Loan Document, it may make any compromise or settlement of the action
or proceeding.  Beneficiary, if it so chooses, may participate in any action or
proceeding relating to condemnation or taking of all or part of the Collateral,
and may join Grantor in adjusting any loss covered by insurance.

          (c) All proceeds of these assigned claims, other property and rights
which Grantor may receive or be entitled to shall be paid to Beneficiary.  In
each instance, Beneficiary shall apply those proceeds first toward reimbursement
of all of

                                       17
<PAGE>
 
Beneficiary's costs and expenses of recovering the proceeds, including
attorneys' fees.

          (d) If, in any instance, each and all of the following conditions are
satisfied in Beneficiary's reasonable judgment, Beneficiary shall permit Grantor
to use the balance of the proceeds ("Net Claims Proceeds") to pay costs of
repairing or reconstructing the Collateral in the manner described below:  (i)
the plans and specifications, cost breakdown, construction contract,
construction schedule, contractor and payment and performance bond for the work
of repair or reconstruction must all be acceptable to Beneficiary; (ii)
Beneficiary must receive evidence satisfactory to it that after repair or
reconstruction, the Collateral will be at least as valuable as it was
immediately before the damage or condemnation occurred; (iii) the Net Claims
Proceeds must be sufficient in Beneficiary's determination to pay for the total
cost of repair or reconstruction, including all associated development costs and
interest projected to be payable on the Note until the repair or reconstruction
is complete; or Grantor must provide its own funds in an amount equal to the
difference between the Net Claims Proceeds and a reasonable estimate, made by
Grantor and found acceptable by Beneficiary, of the total cost of repair or
reconstruction; (iv) Beneficiary must receive evidence satisfactory to it that
all Leases which it may find acceptable will continue after the repair or
reconstruction is complete; (v) Beneficiary has received evidence satisfactory
to it, that reconstruction and/or repair can be completed at least three (3)
months prior to the date the Note secured by this Deed of Trust is due and
payable; and (vi) no default under any of the Loan Documents shall have occurred
and be continuing.  If the foregoing conditions are met to Beneficiary's
satisfaction, Beneficiary shall hold the Net Claims Proceeds and any funds which
Grantor is required to provide and shall disburse them to Grantor to pay costs
of repair or reconstruction upon presentation of evidence reasonably
satisfactory to Beneficiary that repair or reconstruction has been completed
satisfactorily and lien-free.  However, if Beneficiary finds that one or more of
the conditions are not satisfied, it may apply the Net Claims Proceeds to pay or
prepay some or all of the Note.

                                   ARTICLE V
                                   ---------

     1. DEFAULT--REMEDIES.

          (a) Grantor will be in default under this Deed of Trust if (i) Grantor
fails to make any payment when due under the Note, this Deed of Trust or any
other Loan Document; (ii) Grantor fails to perform any other covenant, agreement
or obligation to be performed by Grantor under this Deed of Trust or any other
Loan Document; (iii) any representation or warranty contained in this

                                       18
<PAGE>
 
Deed of Trust or any other Loan Document, or any financial information furnished
by Grantor or its agents to Beneficiary in connection with the Loan, proves to
be false or misleading in any material respect; (iv) Grantor defaults under any
lease or other contract or agreement relating to the Collateral, and such
default is not cured within the applicable cure period, if any; (v) Grantor
defaults under any other Loan Document; (vi) Grantor or any guarantor of the
Loan fails to pay his, her or its debts generally as they become due, or files a
petition or action for relief under any bankruptcy, reorganization or insolvency
laws or makes an assignment for the benefit of creditor; or (vii) an involuntary
petition is filed against Grantor or any guarantor of the Loan under any
bankruptcy, reorganization or other insolvency laws, or a custodian, receiver or
trustee is appointed to take possession, custody or control of the Collateral or
any other properties of Grantor, or the assets of any guarantor of the Loan, and
such petition or appointment is not set aside, withdrawn or dismissed within
thirty (30) days from the date of filing or appointment.

          (b) In the event of a default Beneficiary may declare the Secured
Obligations, including the Loan and all other indebtedness evidenced by the Note
or any other Loan Document, immediately due and payable after notice as set
forth in Section 2 below, and/or exercise its rights and remedies under the Loan
Documents and applicable law including foreclosure of this Deed of Trust
judicially as a mortgage or non-judicially pursuant to the power of sale.
Beneficiary's exercise of any of its rights and remedies shall not constitute a
waiver or cure of a default.  Beneficiary's failure to enforce any default shall
not constitute a waiver of the default or any subsequent default.  In the event
of foreclosure, the cost of the title premium for the trustee's sale guarantee
(or equivalent title policy or report) shall be paid for by Grantor.  If the
Loan Documents are referred to an attorney for enforcement or preservation of
Beneficiary's rights or remedies, whether or not suit is filed or any
proceedings are commenced, Grantor shall pay all Beneficiary's costs and
expenses including Trustee's and attorneys' fees (including attorneys' fees for
any appeal, bankruptcy proceeding or any other proceeding), accountants' fees,
appraisal and inspection fees and cost of title report.

     2.  NOTICE AND OPPORTUNITY TO CURE. Notwithstanding any other provision of
this Deed of Trust, Beneficiary shall not accelerate the maturity of one or more
of the Secured Obligations (a) because of a monetary default (defined below) by
Grantor unless Grantor fails to cure the default within ten (10) days of the
date on which Beneficiary mails or delivers written notice of the default to
Grantor, or (b) because of a nonmonetary default (defined below) by Grantor
unless Grantor fails to cure the default within thirty (30) days of the date on
which Beneficiary mails or

                                       19
<PAGE>
 
delivers written notice of the default to Grantor.  For purposes of this Deed of
Trust, the term "monetary default" means a failure by Grantor to make any
payment required of it pursuant to the Note or any other Loan Document, and the
term "nonmonetary default" means a failure by Grantor or any other person or
entity to perform any obligation contained in the Note or any other Loan
Document, other than the obligation to make payments provided for in the Note or
any other Loan Document.  If a nonmonetary default is capable of being cured and
the cure cannot reasonably be completed within the thirty (30) day cure period,
the cure period shall be extended up to ninety (90) days so long as Grantor has
commenced action to cure within the thirty (30) day cure period, and in
Beneficiary's opinion, Grantor is proceeding to cure the default with due
diligence.  None of the foregoing shall be construed to obligate Beneficiary to
forebear in any other manner from exercising its remedies and Beneficiary may
pursue any other rights or remedies which Beneficiary may have because of a
default.

     3.  CUMULATIVE REMEDIES. To the fullest extent allowed by law, all
Beneficiary's and Trustee's rights and remedies specified in the Loan Documents
(including this Deed of Trust) are cumulative, not mutually exclusive and not in
substitution for any rights or remedies available at law or in equity.  Without
waiving its rights in the Collateral, Beneficiary may proceed against Grantor or
may proceed against any other security or guaranty for the Secured Obligations,
in such order and manner as Beneficiary may elect.  The commencement of
proceedings to enforce a particular remedy shall not preclude the discontinuance
of the proceedings and the commencement of proceedings to enforce a different
remedy.

     4.  ENTRY. After a default, Beneficiary, in person, by agent or by court
appointed receiver, may enter, take possession of, manage and operate all or any
part of the Collateral, and may also do any and all other things in connection
with those actions that Beneficiary may consider necessary and appropriate to
protect the security of this Deed of Trust, including taking and possessing all
of Grantor's or the then owner's books and records pertaining to the ownership,
operation or maintenance of the Property and the other collateral described
above; entering into, enforcing, modifying, or canceling Leases on such terms
and conditions as Beneficiary may consider proper; obtaining and evicting
tenants; fixing or modifying Rents; collecting and receiving any payment of
money owing to Grantor; completing any unfinished construction; and/or
contracting for and making repairs and alterations.

     5.  APPOINTMENT OF RECEIVER. In the event of a default, Grantor consents
to, and Beneficiary, to the fullest extent permitted by applicable law, shall be
entitled, without notice, bond or regard to the adequacy of the Collateral, to
the appointment of a receiver for the Collateral.  The receiver shall

                                       20
<PAGE>
 
have, in addition to all the rights and powers customarily given to and
exercised by a receiver, all the rights and powers granted to Beneficiary by the
Loan Documents.  The receiver shall be entitled to receive a reasonable fee for
management of the Property.  If Grantor is an occupant of the Property,
Beneficiary has the right to require Grantor to pay rent at fair market rates
and the right to remove Grantor from Property if Grantor fails to pay rent.

     6.  SALE OF PROPERTY AFTER DEFAULT. Following a default and the
foreclosure of this Deed of Trust, either judicially or non-judicially, the
Collateral may be sold separately or as a whole, at the option of Beneficiary.
In the event of a trustee's sale of the Collateral pursuant to the power of sale
granted herein, Beneficiary hereby assigns its security interest in the personal
property Collateral to the trustee.  Beneficiary may also realize on the
personal property Collateral in accordance with the remedies available to
secured parties under the Uniform Commercial Code or at law.  In the event of a
trustee's sale, Grantor, and the holder of any subordinate liens or security
interest with actual or constructive notice hereof, waive any equitable,
statutory or other right they may have to require marshaling of assets in
connection with the exercises of any of the remedies permitted by applicable law
or provided herein, or to direct the order in which any of the Collateral will
be sold in the event of any sale under this Deed of Trust or foreclosure in the
inverse order of alienation.

     7.  FORECLOSURE OF LESSEE'S RIGHT--SUBORDINATION. Beneficiary shall have
the right, at its option, to foreclose this Deed of Trust subject to the rights
of any lessees of the Property.  Beneficiary's failure to foreclose against any
lessee shall not be asserted as a claim against Beneficiary or as a defense
against any claim by Beneficiary in any action or proceeding.  Beneficiary at
any time may subordinate this Deed of Trust to any or all of the Leases except
that Beneficiary shall retain its priority claim to any condemnation or
insurance proceeds.

     8.  REPAIRS DURING REDEMPTION. In the event of a judicial foreclosure the
purchaser during any redemption period may make such repairs and alterations to
the Property as may be reasonably necessary for the proper operation, care,
preservation, protection and insuring of the Property.  Any sums so paid,
together with interest from the date of the expenditure at the rate provided in
the judgment, shall be added to the amount required to be paid for redemption of
the Property.

                                   ARTICLE VI
                                   ----------

     1.  ADDITIONAL SECURITY DOCUMENTS. Grantor shall within fifteen (15) days
after request by Beneficiary execute and deliver any financing statement,
renewal, affidavit, certificate,

                                       21
<PAGE>
 
continuation statement, or other document Beneficiary may request in order to
perfect, preserve, continue, extend, or maintain security interests or liens
granted herein to Beneficiary and the priority of such security interests or
liens.  Grantor shall pay all costs and expenses incurred by Beneficiary in
connection with the preparation, execution, recording, filing, and refiling of
any such document.

     2.  RECONVEYANCE AFTER PAYMENT. Upon written request of Beneficiary
stating that all obligations secured by this Deed of Trust have been paid,
Trustee shall reconvey, without warranty, the Collateral then subject to the
lien of this Deed of Trust.  Grantor shall pay any costs, trustee's fees and
recording fees incurred in so reconveying the Property.

     3.  NONWAIVER OF TERMS AND CONDITIONS. Time is of the essence with respect
to performance of the obligations under the Loan Documents.  Beneficiary's
failure to require prompt enforcement of any such obligation shall not
constitute a waiver of the obligation or any subsequent required performance of
the obligation.  No term or condition of this Deed of Trust or any other Loan
Documents may be waived, modified or amended except by a written agreement
signed by Grantor and Beneficiary.  Any waiver of any term or condition of the
Loan Documents shall apply only to the time and occasion specified in the waiver
and shall not constitute a waiver of the term or condition at any subsequent
time or occasion.

     4.  WAIVERS BY GRANTOR. Without affecting any of Grantor's obligations
under the Loan Documents, Grantor waives the following:  (a) any right to
require Beneficiary to proceed against any specific party liable for sums due
under the Loan Documents or to proceed against or exhaust any specific security
for sums due under the Loan Documents; (b) notice of new or additional
indebtedness of any Grantor or any other party liable for sums due under the
Loan Documents to Beneficiary; (c) any defense arising out of Beneficiary
entering into additional financing or other arrangements with any Grantor or any
other party liable for sums due under the Loan Documents and any action taken by
Beneficiary in connection with any such financing or other arrangements or any
pending financing or other arrangements; (d) any defense arising out of the
absence, impairment, or loss of any or all rights of recourse, reimbursement,
contribution or subrogation or any other rights or remedies of Beneficiary
against any Grantor or any other party liable for sums due under the Loan
Documents or any Collateral; and (e) any obligation of Beneficiary to see to the
proper use and application of any proceeds advanced pursuant to the Loan
Documents.

                                       22
<PAGE>
 
     5.  RIGHT OF SUBROGATION. Beneficiary is subrogated to the rights, whether
legal or equitable, of all beneficiaries, mortgagees, lienholders and owners
directly or indirectly paid off or satisfied in whole or in part by any proceeds
advanced by Beneficiary under the Loan Documents, regardless of whether such
parties assigned or released of record their rights or liens upon payment.

     6.  JOINT AND SEVERAL LIABILITY. If there is more than one Grantor of this
Deed of Trust, their obligations shall be joint and several.

     7.  STATEMENT OF AMOUNT OWING. Grantor within fifteen (15) days after
request by Beneficiary will furnish Beneficiary a written statement of the
amount due under the Loan Documents, any offsets or defenses against the amount
claimed by Grantor, and such other factual matters as Beneficiary may reasonably
request.

     8.  BOOKS AND RECORDS; FINANCIAL STATEMENTS.

          (a) Grantor will keep and maintain at Grantor's address stated above,
or such other place as Beneficiary may approve in writing, books of accounts and
records adequate to reflect correctly the results of the operation of the
Property and copies of all written contracts, leases and other instruments which
affect the Property.  Such books, records, contracts, leases and other
instruments shall be subject to examination, inspection and copying at any
reasonable time by Beneficiary.  Except as otherwise agreed in writing by
Beneficiary, Grantor shall provide to Beneficiary within ninety (90) days after
the end of each of Grantor's fiscal years (or within twenty (20) days of
Beneficiary's written request therefor if Grantor is in default), for each
Grantor, for each general partner of Grantor if Grantor is a partnership, and
for each guarantor of all or any of the Secured Obligations, a complete and
current financial statement, together with a statement of income and expenses of
the Property and a statement of changes in financial position with respect to
the Property for the prior year, each in reasonable detail and certified by
Grantor, the general partner or the guarantor, as the case may be.  At the same
time, Grantor shall also furnish a current rent roll for the Property, certified
by Grantor, which shall include such information as Beneficiary may require,
including the name of each tenant, the lease expiration date, the monthly rent,
the date to which rent has been paid, and any deposits or prepaid rent Grantor
is holding.

          (b) All financial statements shall be prepared in accordance with
generally accepted accounting principles, consistently applied, or such other
accounting practices as Beneficiary may approve.  Grantor's compliance with
these provisions shall not limit or affect Grantor's obligations to

                                       23
<PAGE>
 
comply with financial, tax and operation covenants and reporting requirements
under any other agreement between Grantor and Beneficiary whether or not such
other agreement is related to the Secured Obligations.  If any of the reporting
requirements in this Section 8 are inconsistent with the reporting requirements
in any such other agreement, the reporting requirements in such other agreement
shall control.

     9.  APPRAISALS. In the event of a default Beneficiary may obtain a current
regulatory conforming appraisal of the Collateral.  In addition, appraisals may
be commissioned by Beneficiary when required by laws and regulations which
govern Beneficiary's lending practices.  The cost of all such appraisals (and
related internal review fees and costs) will be paid by Grantor within fifteen
(15) days after request by Beneficiary.

     10.  EVASION OF PREPAYMENT FEE. If Grantor is in default, whether
Beneficiary has accelerated the maturity of the indebtedness or not, any tender
of payment sufficient to satisfy all sums due under the Loan Documents made at
any time prior to foreclosure sale shall constitute an evasion of the prepayment
terms of the Note, if any, and shall be deemed a voluntary prepayment.  Any such
payment, to the extent permitted by law, shall include the additional payment
required under the prepayment fee provision in the Note, if any, or if at that
time prepayment is not permitted, then such payment, to the extent permitted by
law, will include an additional payment of five percent (5%) of the then
principal balance.

     11.  PAYMENT OF NEW TAXES. If any federal, state or local law is passed
subsequent to the date of this Deed of Trust which requires Beneficiary to pay
any tax because of this Deed of Trust or the sums due under the Loan Documents
(excluding income taxes), then Grantor shall pay to Beneficiary on demand any
such taxes if it is lawful for Grantor to pay them, or, in the alternative
Grantor may repay all sums due under the Loan Documents plus any prepayment fee
within thirty (30) days of such demand.

     12.  INTENTIONALLY OMITTED. 

     13.  NOTICES. Any notice given by Grantor, Trustee or Beneficiary shall be
in writing and shall be effective (1) on personal delivery to the party
receiving the notice or (2) on the third day after deposit in the United States
mail, postage prepaid with return receipt requested, addressed to the party at
the address set forth above (or such other address as a party may specify by
written notice given pursuant to this paragraph), or with respect to the
Grantor, to the address at which Beneficiary customarily or last communicated
with Grantor.

                                       24
<PAGE>
 
     14.  CONTROLLING DOCUMENT. In the event of a conflict or inconsistency
between the terms and conditions of this Deed of Trust and the terms and
conditions of any other of the Loan Documents (except for any separate
assignment of the Rents and/or the Leases and any loan agreement which shall
prevail over this Deed of Trust), the terms and conditions of this Deed of Trust
shall prevail.

     15.  INVALIDITY OF TERMS AND CONDITIONS. If any term or condition of this
Deed of Trust is found to be invalid, the invalidity shall not affect any other
term or condition of the Deed of Trust and the Deed of Trust shall be construed
as if not containing the invalid term or condition.

     16.  LEGISLATION AFFECTING BENEFICIARY'S RIGHTS. If enactment or
expiration of applicable laws has the effect of rendering any provision of the
Note or this Deed of Trust unenforceable according to its terms, and Beneficiary
in good faith believes the affect of such change in laws will adversely impact
the security for the Note or Grantor's obligation or ability to repay the Loan,
Beneficiary, at its option, may require immediate payment in full of all sums
secured by this Deed of Trust and may invoke any remedies permitted herein.

     17.  RULES OF CONSTRUCTION. This Deed of Trust shall be construed so that,
whenever applicable, the use of the singular shall include the plural, the use
of the plural shall include the singular, and the use of any gender shall be
applicable to all genders and shall include corporations, partnerships and
limited partnerships.  This Deed of Trust inures to the benefit of, and binds
all parties named herein and their successors and assigns. The headings to the
various sections have been inserted for convenience of reference only and shall
not be used to construe this Deed of Trust.

     18.  APPLICABLE LAW. The Loan Documents shall be governed by and construed
in accordance with the laws of the State of Washington.

order of SEATTLE-FIRST NATIONAL BANK, a national banking association ("Lender"),
at its principal office in Seattle, Washington, or at such other place or places
or to such other party as the "Holder" (defined below) may from time to time
designate in writing, the principal sum of Eleven Million Five Hundred Thousand
Dollars ($11,500,000), or so much thereof as may be advanced, in lawful money of
the United States of America, together with interest thereon, on the following
agreements, terms and conditions.  The term "Holder" as used in this Note means
Lender or any future holder of this Note, and their successors and assigns.

     1.   TERM.  The unpaid principal balance of this Note and all unpaid
          ----                                                           
accrued interest thereon and other sums payable by Maker in connection with this
Note shall be due and payable in full one hundred twenty (120) months from the
first day of the first calendar month following the initial advance by the
Holder under this Note (the "Maturity Date").

     2.   INTEREST.  Interest shall commence to run on each advance under this
          --------                                                            
Note from the date of the advance and will be computed on the outstanding
balance of this Note as it exists from time to time.  Interest shall accrue on
the principal balance of this Note either at a variable interest rate as
provided in subparagraph 2(a) below (the "Variable Rate"), or at a fixed
interest rate as provided in subparagraph 2(b) below (the "Fixed Rate").  If
Maker elects a Fixed Rate pursuant to subparagraph 2(b) below for a "Fixed Rate
Period" (defined below) less then full term of this Note (or the remainder
thereof, as applicable), after the expiration of the applicable Fixed Rate
Period, interest on this Note shall be calculated at a Variable Rate unless
Maker again elects to have interest calculated at a Fixed Rate pursuant to
subparagraph 2(b) below.  The Holder still shall have no duty or obligation to
notify Maker that a Fixed Rate Period is about to expire and that the interest
rate on this Note is about to revert to the Variable Rate.  After maturity, or
after default, interest shall accrue on the outstanding principal balance of
this Note at an annual rate equal to four percentage points (4%) per annum above
the interest rate otherwise applicable to this Note.  Interest on this Note
shall be calculated using a 30-day month and a 360-day year.

                                       1

          (a) Variable Rate.  Unless Maker elects to have interest calculated at
              -------------                                                     
the Fixed Rate pursuant to subparagraph 2(b) below, interest shall accrue on the
principal balance of this Note at the Variable Rate.  The initial Variable Rate
shall be equal to the "LIBOR Index" (defined below) as of the date of the
initial advance under this Note, plus one and one-quarter percentage points
(1.25%) per annum, rounded to the next highest one-eighth of one percent
(0.125%).  The Variable Rate, if applicable, will change five (5) months after
the first payment date at the applicable Variable Rate, as stated in Paragraph 3
below, and every sixth (6th) month thereafter (each such date being referred to
in this Note as an "Interest Change Date").

              (i) LIBOR Index - Current Index - Changes in the Variable Rate
will be based on changes in the 180-day LIBOR as defined below (the "LIBOR
Index").  If the LIBOR Index is no longer available, the Holder will choose a
new index based upon comparable information and give Maker notice of the
choice.  The most recently available LIBOR Index fifteen (15) Business Days
before each Interest Change Date is the "Current Index".

              (ii) Calculation of Variable Rate - Before each Interest Change
Date, if applicable, the Holder will calculate the new Variable Rate which
shall be equal to the Current Index, plus one and one-quarter percentage points
(1.25%) per annum, rounded to the next highest one-eighth of one percent
(0.125%).  This new interest rate will be the new Variable Rate until the next
Interest Change Date.

              (iii)  LIBOR means the London Interbank Offer Rate, adjusted at
the Holder's option for governmentally mandated statutory reserves, deposit
insurance, regulatory capital, taxes and assessments, if any, and is the average
of the rates of interest, on a per annum basis, at which deposits in United
States dollars having a term of 180 days are offered by major banks in
immediately available funds to prime banks in the London Interbank market at
11:00 A.M. (London time) on the date of the initial advance, or the day which is
fifteen (15) Business Days prior to the applicable Interest Change Date, as
applicable.  This rate is reported on Telerate, a national and international
medium which provides interest rate quotations daily, as quoted by the British
Bankers Association as Interest Settlement Rates on page 3750 (or such other
page as may replace it).  Such interest rate quotation, as provided by Telerate,
shall be deemed conclusive and final with respect to LIBOR determinations for so
long as Telerate continues to make such interest rate reports.  If Telerate or
the British Bankers Association report is no longer available for 180-day
maturities, a comparable publication or report containing such information
selected by the Holder will be used.  If there is no such publication or
comparable publication containing such information, the 180-day LIBOR shall be
the average rate (rounded

                                       2
<PAGE>
 
if necessary to the nearest one-thousandth of a percent) at which dollar
deposits having a maturity of 180 days are offered by at least two major banks
in an interbank market where Eurodollars are being traded, to prime banks in
immediately available funds on the LIBOR determination date described above or
as soon thereafter as such offer quotes can be obtained.

              (iv) Business Day means a day on which commercial banks are
generally open for business in Seattle, Washington and London, England.
   
              (v) The amount of adjustment for reserves, deposit insurance,
regulatory capital, taxes and assessments may change on any Interest Change Date
depending on such charges being assessed against the Holder at that time.  Such
charges may change due to various factors, including but not limited to, changes
in the requirements for reserves and capital adequacy promulgated by the Federal
Reserve System of the United States and/or other state and federal regulatory
agencies, statutory changes affecting the Holder, and/or imposition of taxes,
FDIC fees and/or assessments.  Each determination of an adjustment amount shall
be made by the Holder in its sole and absolute discretion and shall be
conclusive and binding upon Maker and shall be determined without benefit of or
credit for prorations, exceptions or offsets that may be available to the Holder
from time to time.

          (b) Fixed Rate.  Prior to the date of the initial advance by Lender
              ----------                                                     
under this Note, Maker may elect by written notice (a "Fixed Rate Notice") to
the Holder to have interest on the entire principal amount of this Note
calculated at a Fixed Rate for a Fixed Rate Period, the duration of which is the
entire term of this Note or a lesser period of three (3) years, five (5) years
or seven (7) years.  Further, so long as Maker is not in default under the terms
of this Note or any other documents or instruments executed by Maker in
connection with the loan (the "Loan") evidenced by this Note (collectively with
this Note, the "Loan Documents"), Maker, at its option, may elect by a Fixed
Rate Notice to the Holder to have interest calculated on the entire principal
balance of this Note at a Fixed Rate calculated as provided below for a Fixed
Rate Period, the duration of which is the remainder of the term of this Note or
a lesser period of three (3) years, five (5) years or seven (7) years; provided
no Fixed Rate Period may extend beyond the Maturity Date.  Notwithstanding any
of the foregoing, Maker's option to fix the interest rate on this Note is
subject to the availability to the Holder of matchfunding opportunities for a
time period equivalent to the applicable Fixed Rate Period.  For purposes of
this Note, the term "Fixed Rate Period" means the period of time for which a
Fixed Rate applies as specified in a Fixed Rate Notice from Maker to the Holder.

                                       3
<PAGE>
 
            (i) Calculation of Fixed Rate - If Maker elects to have a Fixed Rate
apply to this Note, interest shall accrue on the principal balance of this Note
at a per annum rate equal to Lender's reserve adjusted "Fixed Rate Index" as
quoted by Lender on the date the interest rate is fixed, for a period equivalent
to the applicable Fixed Rate Period, plus one and one-quarter percentage points
(1.25%) per annum, rounded upward to the next highest one-eighth of one percent
(0.125%).  The Fixed Rate Index may be adjusted at the Holder's option to
reflect governmentally mandated statutory reserves, deposit insurance,
regulatory capital, taxes and assessments, if any, as set forth in subparagraph
2(a)(v) above.

            (ii) Date of Conversion - The interest rate applicable to this Note
will be converted to the Fixed Rate on the date the Holder receives a Fixed Rate
Notice, provided the Fixed Rate Notice is received before noon, Seattle time, on
a Business Day.  If a Fixed Rate Notice is received by Holder after noon,
Seattle time, on a Business Day, the interest rate applicable to this Note will
convert to a Fixed Rate on the next Business Day.  For purposes of this
subparagraph 2(b)(ii) only, the term "Business Day" means a day on which
commercial banks are generally open for business in Seattle, Washington.

     3.   PAYMENTS.  Maker shall make monthly payments of principal and interest
          --------                                                              
to the Holder in amounts sufficient to fully amortize the principal balance of
this Note over a twenty-five (25) year amortization period in substantially
equal monthly payments, based on the interest rate applicable to this Note,
calculated as provided below.  Such monthly payments of principal and interest
shall be due on the first day of each calendar month during the term of this
Note, commencing on the first day of the second calendar month following the
month in which the Holder initially disburses funds under this Note, or if the
interest rate reverts to a Variable Rate after the expiration of a Fixed Rate
Period, on the first day of the second calendar month following the month in
which the Fixed Rate Period expires.  On the Maturity Date, the unpaid principal
balance of this Note, all unpaid accrued interest and all other sums then due
and owing pursuant to this Note or any other Loan Documents shall be due and
payable in full.  Each payment shall be applied first, at Holder's option, to
any unpaid late charges or other sums payable by Maker under this Note or any
other Loan Document, then to interest to the due date of the payment, and then
to the principal balance of this Note.  At the option of the Holder, all
payments under this Note, including payments at maturity, shall be made in same
day funds.  The monthly payments required on this Note shall be calculated as
follows:

          (a) Variable Rate Payments.  If interest is accruing on this Note at a
              ----------------------                                            
Variable Rate, the amount of the monthly payments shall be sufficient to fully
amortize the principal balance of this

                                       4
<PAGE>
 
Note at the applicable Variable Rate, in substantially equal monthly payments
over the amortization period specified above, or the balance thereof as
applicable.  At or promptly after the closing of the Loan (or after the
expiration of a Fixed Rate Period, as applicable), the Holder will provide Maker
with a closing statement (or other written notice) which will confirm the
Variable Rate and the amount of the principal and interest payments due under
this Note.  The monthly payment will change after each Interest Change Date to
an amount sufficient to repay the then unpaid principal balance of this Note in
full at the then current interest rate, in substantially equal monthly payments
over the balance of the amortization period specified above.  Until the payment
is again changed, Maker shall pay the new monthly payment each month beginning
on the first day of the first calendar month after the applicable Interest
Change Date.  The Holder will mail or deliver to Maker a notice of any changes
in the Variable Rate applicable to this Note, and any resulting changes in the
monthly payments required under this Note, prior to the date the first payment
is due after the applicable Interest Change Date.

          (b) Fixed Rate Payments.  If interest is accruing on this Note at a
              -------------------                                            
Fixed Rate, the amount of the monthly payments shall be in an amount sufficient
to fully amortize the principal balance of this Note at the applicable Fixed
Rate, in substantially equal monthly payments over the amortization period
specified above, or the remainder thereof, as applicable.  The applicable Fixed
Rate and the amount of the monthly principal and interest payments due under
this Note shall be confirmed in writing by the Holder (either pursuant to a
closing statement or other written notice) after the rate is fixed and before
the date the first payment at the Fixed Rate is due.

     4.   LATE CHARGES; RETURNED ITEM FEE.  If any payment due hereunder is not
          -------------------------------                                      
received by the Holder within fifteen (15) days of the due date, at the option
of the Holder without waiving such default or any of its remedies, a late charge
shall be added to the delinquent payment in the amount of four percent (4%) of
the full payment not timely paid.  Any such late charge shall be due and payable
on demand, and the Holder, at its option, may (a) refuse any late payment or any
subsequent payment unless accompanied by the applicable late charge, (b) add the
late charge to the principal balance of this Note, (c) pay any late charge with
advances of the undisbursed proceeds of the Loan, if any, or (d) treat the
failure to pay the late charge as demanded as a default under this Note.  If a
late charge is added to the principal balance of this Note, it shall bear
interest at the same rate as the principal balance of this Note.  Any payment to
Holder by check, draft or other item shall be received by Holder subject to
collection and will constitute payment when collected not when received.  For
each "nsf" or returned check, draft or other item, in addition to any applicable
late charge, Maker shall pay to the

                                       5
<PAGE>
 
Holder on demand a returned item fee in accordance with the Holder's schedule of
such fees then in effect.

     5.   PREPAYMENT.  So long as interest is calculated on this Note at a
          ----------                                                      
Variable Rate, this Note may be prepaid in whole or in part at any time without
the payment of a prepayment fee.  During any period when a Fixed Rate is
applicable to this Note, this Note may be prepaid only as set forth in Exhibit A
                                                                       ---------
attached.  Partial prepayments, if permitted, shall not postpone nor reduce the
amount of the monthly payments required under this Note, provided the amount of
the required monthly payments will be recalculated at the end of the applicable
LIBOR period or Fixed Rate Period to reflect the reduction in the principal
balance of this Note.

     6.   DEFAULT.  After a default under any of the Loan Documents, or if Maker
          -------                                                               
fails to make any payment under this Note when due, the then Holder, at its
option, without notice to Maker (except as provided below), may declare the
entire principal balance of this Note and all unpaid accrued interest thereon
and other charges payable by Maker pursuant to this Note or any other Loan
Document, immediately due and payable in full, and the Holder may exercise any
and all other rights or remedies available to it under any Loan Document, at law
or in equity.  Any additional interest due because of a default shall accrue
from the date of default and shall be paid as a condition to the curing of the
default.  Notwithstanding the foregoing, the Holder will not accelerate the
Maturity Date (a) because of a monetary default by Maker under this Note or any
other Loan Document unless the default is not cured within ten (10) days of the
date on which the Holder mails or delivers written notice of the default to
Maker, or (b) because of a nonmonetary default by Maker under this Note or any
other Loan Document unless the default is not cured within thirty (30) days of
the date on which the Holder mails or delivers written notice of the default to
Maker.  For purposes of this Note, the term "monetary default" means a failure
by Maker to make any payment required pursuant to this Note or any other Loan
Document, and the term "nonmonetary default" shall mean a failure by Maker to
perform any obligation contained in this Note or any other Loan Document, other
than the obligation to make the payments provided for in this Note or any other
Loan Document.  If the nonmonetary default is capable of being cured and cannot
reasonably be made within the thirty (30) day cure period, the cure period shall
be extended up to ninety (90) days so long as Maker has commenced action to cure
within the thirty (30) day cure period, and in the Holder's opinion, Maker is
proceeding to cure the default with due diligence.  None of the foregoing shall
be construed to obligate the Holder to forbear in any other manner from
exercising its remedies and the Holder may pursue any other rights or remedies
which the Holder may have because of the default.

                                       6
<PAGE>
 
     7.   CUMULATIVE REMEDIES.  The rights and remedies of any Holder under this
          -------------------                                                   
Note or any other Loan Document, or at law or in equity, shall be cumulative and
concurrent, may be pursued singly, successively or together against Maker, any
guarantor of this Note, or any security for this Note.  A failure by any Holder
to exercise its option to accelerate this Note upon the occurrence of a default
or to exercise any other rights to which it may be entitled shall not constitute
a waiver of the right to exercise such option or any such rights in the event of
any subsequent default, whether of the same or a different nature.

     8.   WAIVERS.  Maker and all endorsers, guarantors and all other persons or
          -------                                                               
entities who may become liable for all or any part of the obligations evidenced
by this Note, jointly and severally: waive diligence, presentment, protest and
demand, and also notice of protest, demand, non-payment, dishonor or maturity
and also recourse to suretyship defenses generally; and consent to any and all
renewals, extensions and modifications of the terms of this Note or any other
Loan Document, including the time for payment, and agree any such renewal,
extension or modification or the release or substitution of any security for the
indebtedness evidenced by this Note or any other indulgences, shall not affect
the liability of said parties for the indebtedness evidenced by this Note.  Any
such renewals, extensions, modifications, releases or indulgences may be made
without notice to such parties.

     9.   COSTS AND EXPENSES.  Whether or not suit is brought Maker shall pay on
          ------------------                                                    
demand all costs and expenses, including attorneys' fees and costs incurred by
or on behalf of the Holder in connection with this Note, including without
limitation costs incurred in the collection of this Note, in protecting the
security for this Note or in foreclosing or enforcing this Note or any other
Loan Document, or resulting from the Holder being made a party to any litigation
because of the existence of this Note or any other Loan Document.  Without
limiting the generality of the foregoing, if Maker becomes the subject of any
bankruptcy or insolvency proceeding, Maker shall pay all fees and expenses
incurred by the Holder in connection with such bankruptcy or insolvency
proceeding.

     10.  MAXIMUM INTEREST.  Maker represents and warrants the proceeds of this
          ----------------                                                     
Note shall be used solely for commercial, investment and business purposes, and
not for personal, family or household purposes.  Notwithstanding any other
provision of this Note or any other Loan Document, interest, loan fees and
charges payable by reason of the indebtedness evidenced by this Note shall not
exceed the maximum, if any, permitted by applicable law.  If by virtue of
applicable law, sums in excess of such maximum would otherwise be payable, then
such excess sums shall be construed as having been immediately applied by the
Holder to the principal balance of this Note when received.  If at the time any
such sum is received by the Holder, the principal balance of this Note has been

                                       7
<PAGE>
 
paid in full, such sums shall be promptly refunded by the Holder to Maker, less
any sums due to the Holder.

     11.  SECURITY.  This Note is secured by a deed of trust of even date (the
          --------                                                            
"Deed of Trust") encumbering certain real property located in Snohomish County,
Washington (the "Property").  Unless otherwise specified in this Note, all
notices given pursuant to this Note must be in writing and will be effectively
given if given in accordance with the terms of the Deed of Trust.

     12.  GENERAL.  This Note shall be binding upon Maker and Maker's successors
          -------                                                               
and assigns.  If Maker consists of more than one person or entity, all of such
persons and entities shall be jointly and severally liable for Maker's
obligations under this Note.  This Note is governed by and shall be construed in
accordance with the laws of the State of Washington.  Each person or entity
executing this Note consents to the non-exclusive personal jurisdiction and
venue of the courts of the State of Washington and the United States federal
courts located therein, in any action relating to or arising out of the
enforcement or interpretation of this Note or any other Loan Document.  Each
such person or entity further agrees not to assert in any such action that the
proceeding has been brought in an inconvenient forum.

     13.  ARBITRATION.  Any dispute relating to this Note or the Loan (whether
          -----------                                                         
in contract or tort) shall be settled by arbitration if requested by Maker, the
Holder or any other party to the dispute (such as a guarantor); provided, both
                                                                --------      
Maker and the Holder must consent to a request for arbitration relating to an
obligation secured by real property.  The arbitration proceedings shall be held
in Seattle, Washington in accordance with the commercial arbitration rules of
the American Arbitration Association, and the United States Arbitration Act
(i.e., Title 9, U.S.C.).  There shall be one arbitrator who shall decide whether
an issue is arbitrable or whether any claim is barred by a statute of
limitations.  Judgment on the arbitration award may be entered in any court
having jurisdiction.  Commencement of a lawsuit shall not constitute a waiver of
the right of any party to request arbitration if the lawsuit is contested.  Each
party shall have the right before, during and after the commencement of any
arbitration proceeding to exercise any of the following remedies, in any order
or concurrently: (i) self-help remedies such as setoff or repossession; (ii)
judicial or nonjudicial foreclosure against real or personal property
collateral; and (iii) provisional remedies including injunction, appointment of
receiver, attachment, claim and delivery and replevin.  The exercise of any such
remedy shall not waive a party's right to request arbitration.  Nothing in this
paragraph shall limit in any way any right the Holder may have to foreclose the
Deed of Trust judicially as a mortgage, or nonjudicially pursuant to the power
of sale.

     14.  DISPUTED OBLIGATIONS.  All communications concerning disputed debts
          --------------------                                               
and obligations of Maker under this Note or any other Loan Document, including
without limitation disputes as to the amount of any payment, fee or charge, and

          --------                                                           
Maker shall pay Lender a loan fee in the amount of five-eighths percent (%) of

Inc., a Delaware corporation ("ATL"), are parties to a Revolving Credit Loan
Agreement and Guaranty dated June 26, 1992, as amended from time to time (the
"Loan Agreement").  Maker agrees if Maker or ATL defaults under the Loan
Agreement and does not cure the default prior to the expiration of the
applicable cure period, if any, such default will constitute a default under
this Note and the other Loan Documents and no additional notice of default shall
be required under Paragraph 6 of this Note.

                                   PREPAYMENT


     If the interest rate converts to the Fixed Rate the principal balance of
this Note may be prepaid in whole or in part, at any time provided (i) a
prepayment fee is paid as set forth below, (ii) each partial prepayment is in an
amount of $10,000 or more, and (iii) partial prepayments may be no more frequent
than once per month.  The prepayment fee shall be due and payable whether the
prepayment is by voluntary prepayment, operation of law, acceleration or
otherwise.  The amount of the prepayment fee depends on the following:

     1.   The amount by which certain "Reference Rates", as defined below, have
changed between the time this Note is prepaid and the date the interest rate
converts to the Fixed Rate.

     2.   A prepayment fee factor (see "Prepayment Fee Factor Schedule" below).

     3.   The amount of principal prepaid.

                         DEFINITION OF REFERENCE RATES

     The "Reference Rate" used to represent interest rate levels shall be the
bond equivalent yield of the average U.S. Treasury Securities having maturities
equivalent to the remaining period to maturity of the Loan or the last day of
the Fixed Rate Period, as applicable, rounded upward to the nearest month.  The
"Initial Reference Rate" shall be the Reference Rate assigned to the Loan by the
Holder at the time the interest rate converts to the Fixed Rate.  The "Final
Reference Rate" shall be the Reference Rate assigned to the Loan by the Holder
at the time of the prepayment.

     The applicable Reference Rates shall be determined from the Federal Reserve
Statistical Release (Publication H.15) as displayed on Page 119 of the Dow Jones
Telerate Service (or such other page or service as may replace that page or
service for the purpose of displaying rates comparable to said U.S. Treasury
Securities).  If the publishing of the foregoing Statistical Release is ever
discontinued, the applicable Reference Rate shall be based on the publication by
the Board of Governors of the United States Federal Reserve System in
replacement thereof, or if none, the publication which in the Holder's
discretion most nearly corresponds.

                         CALCULATION OF PREPAYMENT FEE

     1.   If the Initial Reference Rate is less than or equal to the Final
Reference Rate, there is no prepayment fee.

                                       1
<PAGE>
 
     2.  If the Initial Reference Rate is greater than the Final Reference Rate,
the prepayment fee shall be equal to the difference between the Initial
Reference Rate and the Final Reference Rate (expressed as a decimal), multiplied
by the appropriate factor from the Prepayment Fee Factor Schedule, multiplied by
the principal amount of the Loan being prepaid.

                     EXAMPLE OF PREPAYMENT FEE CALCULATION

     An amortizing loan with remaining principal of $250,000 is fully prepaid
with twenty-four (24) months remaining until maturity.  An Initial Reference
Rate of 9.000% was assigned to the loan at the time the loan was closed.  The
Final Reference Rate (as determined by the current 24-month U.S. Treasury Rate
on Page 119 of Telerate) is 7.500%.  Rates therefore have dropped 1.500% since
the loan was closed and a prepayment fee applies.  A prepayment fee factor of
1.3% is determined from Table 1 below and the prepayment fee is computed as
follows:

  Prepayment Fee = (0.09 - 0.075) x (1.3) x ($250,000) = $4,875.00

     The Holder of this Note is not required to actually reinvest the prepaid
principal in any U.S. Government Treasury Securities, or otherwise prove its
actual losses, as a condition to receiving a prepayment fee as calculated above.
Maker agrees this prepayment fee is the bargained-for consideration to the
Holder for permitting prepayment and the above is not a liquidated damages
provision.  This prepayment fee provision is to be interpreted in a manner that
would make it enforceable to the fullest extent permitted by law, with any
portion of the fee that is unenforceable being stricken or otherwise changed to
cause the fee, as revised, to be enforced.

          completion of a one-year Period of Service provided he or she is an
          Eligible Employee on such date.

     (b)  An Eligible Employee who is a Part-Time Employee shall become a
          Participant on the first day of any subsequent month following a
          twelve-month period during which he or she is credited with at least
          1,000 Hours of Service.  Such twelve-month period shall commence on
          the Employee's Employment Commencement Date and each January 1
          thereafter.

          Part-Time Employee means an Employee who is employed for less than a
          full-time basis based on uniform rules established by the Committee
          and consistently applied to all persons similarly situated.

2.2  Reemployment After Termination
     ------------------------------

     Upon the reemployment of a Terminated former Participant as an Eligible
     Employee, he or she shall immediately become a Participant.

     An Employee who Terminates prior to becoming a Participant and is later
     reemployed shall become a Participant upon satisfying the requirements of
     Section 2.1.  A Period of Service earned prior to Termination shall not be
     forfeited for purposes of this Section 2.

2.3  Employees in a Bargaining Unit
     ------------------------------

     An Employee belonging to a collective bargaining unit, which has entered an
     agreement with the Participating Company that does not provide for
     retirement benefits under this Plan, shall not qualify for participation.
     If such an Employee is a Participant when such an agreement is entered, the
     Employee shall cease active participation on the effective date of the
     bargaining agreement.  If such an agreement provides for Plan
     participation, a covered Employee may continue or resume participation.

                            BEFORE-TAX CONTRIBUTIONS


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

     (a)  General
          -------

          A Participant who desires to make salary deferrals pursuant to this
          Section 3.1 shall enter a salary deferral agreement with the
          Participating Company at least 15 days prior to the first day of the
          month on which the salary deferral is to commence.  Such agreement
          shall authorize the Company to make payroll deductions equal to a
          whole percentage of Earnings between 2% and 16% designated as Before-
          Tax Contributions.  Payroll deductions shall be based on Earnings for
          each payroll period.

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

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

     (b)  Maximum Dollar Contribution
          ---------------------------

          Notwithstanding the foregoing, Before-Tax Contributions for any
          calendar year to this Plan (and any other plans of Affiliated
          Companies subject to Section 402(g) of the Code) shall not exceed the
          maximum dollar limitation on elective deferrals under Section 402(g)
          of the Code ($8,728 for 1992).

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

     The payroll deduction percentages designated in the Participant's salary
     deferral agreement shall continue in effect regardless of changes in
     Earnings until the Participant elects in writing to change the percentage.
     A Participant may change the deferral amount by completing a new salary
     deferral agreement and submitting it to the Committee.  The agreement will
     become effective on the first day of the month after 15 days from the date

                                       13
<PAGE>
 
     such notice is received by the Committee.  Completion of a salary deferral
     agreement shall automatically revoke all prior salary deferral agreements
     entered into by a Participant.   A Participant may change the deferral
     amount or suspend deferrals as frequently as each month, as long as the
     salary deferral agreement is received by the Committee at least fifteen
     days before the effective date of the change.

     A Participant may discontinue contributions effective on the first day of
     any future month by submitting a request form to the Committee at least 15
     days prior to the effective date.  Contributions may be resumed on the
     first day of any month after having been suspended as long as the salary
     deferral agreement is received by the Committee at least fifteen days
     before the salary deferrals are to commence.

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

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

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

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

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

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

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

     In applying the foregoing tests, Compensation paid to and Before-Tax
     Contributions on behalf of family members (as defined in Code Section
     414(q)(6)(B)) of a Highly Compensated Employee who is a 5% owner or in the
     group consisting of the ten Highly Compensated Employees paid the greatest
     Compensation shall be considered together to

                                       14
<PAGE>
 
     determine a combined ADP for the family group (which is treated as one
     Highly Compensated Employee).

     If for any Plan Year a Highly Compensated Employee is also eligible to
     participate in another cash for deferred arrangement maintained by any
     Affiliated Company, then the ADP of such Highly Compensated Employee shall
     be determined by treating all the cash or deferred arrangements in which he
     or she is eligible to participate and this Plan as one arrangement.

                                   SECTION 4

                               PLAN CONTRIBUTIONS


4.1  Participant and Company Contributions
     -------------------------------------

     (a)  Participant Payroll Deduction Contributions
          -------------------------------------------

          The Company shall make a Participant Before-Tax Contribution on behalf
          of each active Participant in an amount equal to 100% of the salary
          deferral amount pursuant to the Participant's salary deferral
          agreement, as provided in Section 3, for each payroll period.
          Participant contributions shall be credited to the Participant's
          Before-Tax Contribution Account.

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

          The Company shall pay the Participants' Before-Tax Contributions in
          cash to the Trustee within a reasonable time after each pay-period but
          not later than a reasonable time after the end of each month.

     (b)  Employee After-Tax Contributions
          --------------------------------

          A Participant may elect to contribute to the Plan, through payroll
          deductions, an amount equal to a whole percentage of Earnings between
          2% and 16%, reduced by the amount (if any) of the Before-Tax
          Contributions to be made on his behalf.  Such amounts are referred to
          as After-Tax Contributions.  A Participant may make such election by
          filing a written application which authorizes a deduction of
          contributions from his Earnings at least 15 days prior to the first
          day of the month on which a deduction is to commence.  After-Tax
          Contributions shall be credited to the Participant's After-Tax
          Contribution Account.

          An election to make After-Tax Contributions may be modified or
          canceled subject to the same provisions that apply to Before-Tax
          Contributions pursuant to Section 3.2.

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

          The Company shall pay the Participants' After-Tax Contributions in
          cash to the Trustee within a reasonable time after each pay-period but
          not later than a reasonable time after the end of each month.

                                       16
<PAGE>
 
     (c)  Company Matching Contributions
          ------------------------------

          Each Company shall make the Company Matching Contribution for any Plan
          Year in an amount equal to:

          (i)  50% of the first 3% of each Participant's Before-Tax
               Contributions and After-Tax Contributions in respect of Earnings
               paid by the Company during such Plan Year; and

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

          Provided that, Participant Lump Sum Supplemental Contributions
          pursuant to Section 4.1(e) will not be matched by a Company Matching
          Contribution.

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

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

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

     (d)  Supplemental Company Contributions
          ----------------------------------

          On the last day of the Plan Year, each Participating Company may
          contribute a uniform percentage of a Participant's Earnings, on behalf
          of each Participant who completed 1,000 or more Hours of Service
          during the Plan Year and (i) who is employed on the first and last
          days of the Plan Year, (ii) who terminated employment during the Plan
          Year as a result of retirement, Disability or death, or (iii) who was
          employed by the Participating Company but who was transferred during
          the Plan Year to the employ of an Affiliated Company that is not a
          Participating Company.

                                       17
<PAGE>
 
          Amounts contributed by each Participating Company may be different 
          from the amount contributed by another Participating Company.  Amounts
          contributed by each Participating Company will be allocated only to
          Participants employed by that Participating Company, based on Earnings
          paid by that Participating Company.  Such amounts are referred to as
          Supplemental Company Contributions and shall be credited to
          Supplemental Company Contribution Accounts.  The percentage of
          Supplemental Company Contributions shall be determined separately for
          each Participating Company by the Board.

          In the discretion of the Participating Company making the
          contribution, a Supplemental Company Contribution may be based on
          Earnings as defined in Section 1.17.

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

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

     (e)  Lump-Sum Supplemental Contributions
          -----------------------------------

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

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

     (f)  Rollover Contributions
          ----------------------

          An Eligible Employee may request in writing that the Committee permit
          acceptance of a rollover amount which was distributed from another
          qualified plan or conduit Individual Retirement Account (IRA).  The
          amount must be rolled over by the Eligible Employee within 60 days of
          receiving the distribution from the other plan or conduit IRA.  The
          Committee shall have total discretion over acceptance of such amounts
          into this Plan; provided, rollovers of any type of property other than
          cash will not be accepted.  In the event an Eligible Employee is
          permitted to contribute a rollover amount, such amount shall be
          allocated to a

                                       18
<PAGE>
 
          separate, fully vested account and subject to the same terms of the
          Plan as other amounts in a Before-Tax Contribution Account, provided,
          amounts in a Rollover Account may be withdrawn in Service at any time.

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

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

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

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

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

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

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

     The ACP for a specified group of Eligible Employees shall be the average of
     the ratios (calculated separately for each Employee in the group to the
     nearest one-hundredth of one percent of the Employee's Compensation) of (i)
     Company Matching Contributions on behalf of each such Employee and the
     Employee's After-Tax Contributions and Lump-Sum Supplemental Contributions,
     if any, to (ii) the Employee's Compensation earned while eligible to
     participate, determined in accordance with Code Section 401(m) and
     regulations pursuant thereto.  For purposes of the ACP tests, the
     definition of "Compensation" may be modified from year to year to mean any
     definition of compensation that complies with Section 414(s) of the Code.

     In applying the foregoing tests, Compensation paid to and contributions on
     behalf of family members (as defined in Code Section 414(q)(6)(B)) of a
     Highly Compensated Employee who is a 5% owner or in the group consisting of
     the ten Highly Compensated Employees paid the greatest Compensation shall
     be considered together to determine a

                                       19
<PAGE>
 
     combined ACP for the family group (which is treated as one Highly
     Compensated Employee).

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

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

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

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

     (a)  the sum of:

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

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

     (b)  the sum of:

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

          (ii) two plus the greater of the ADP or the ACP for the group of all
               Eligible Employees who are not Highly Compensated Employees (in
               no event shall this amount exceed twice the greater of such ADP
               or ACP).
 
4.5  Corrective Procedures to Satisfy Discrimination Tests
     -----------------------------------------------------

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

                                       20
<PAGE>
 
     The Committee may, in its sole discretion, elect to aggregate Company
     Matching Contributions and/or Supplemental Company Contributions with
     Participant Before-Tax Contributions to the extent necessary to satisfy the
     ADP discrimination test provided such aggregation does not itself result in
     discrimination.  Notwithstanding any Plan provisions to the contrary, any
     Company contributions so aggregated shall be 100% vested as of the date
     contributed to the Plan and shall be subject to the withdrawal provisions
     of Section 7.4 as if they are Before-Tax Contributions.   The ACP test must
     be passed without taking such Company contributions into account.

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

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

     (a)  Mistake of Fact
          ---------------

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

     (b)  Excess Deferrals
          ----------------

          An excess deferral exists for a Participant if Before-Tax
          Contributions under this Plan together with any other plans subject to
          the deferral limit in Code Section 402(g) (for 1992 this limit is
          $8,728) exceed such dollar limitation for any calendar year.

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

          In the event an excess deferral exists in plans maintained by the
          Company and any unrelated employer(s), and a Participant submits a
          written request for a return of excess deferrals by March 1 following
          the calendar year in which an excess deferral occurs (or any other
          date authorized by the Committee), the Committee

                                       21
<PAGE>
 
          shall distribute such excess deferral, adjusted for investment gains
          or losses, less amounts previously returned pursuant to subparagraph
          (c), no later than April 15 following the calendar year in which the
          excess deferral occurred.  Such written request shall contain
          information which the Committee may require.

     (c)  ADP Excess Contribution
          -----------------------

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

          In the event excess deferrals are returned to a Highly Compensated
          Employee whose contributions and Compensation were aggregated with
          other family members for purposes of the ADP test in Section 3.4, such
          returned amounts shall be returned to each family member in the same
          proportion that his or her contributions and Compensation bears to
          total contributions and Compensation of the family member group.

     (d)  ACP Excess Contribution
          -----------------------

          An ACP excess contribution exists if contributions under this Plan on
          behalf of Highly Compensated Employees fail to meet the ACP test
          described in Section 4.3.  Within twelve months after the end of the
          Plan Year for which there is an excess, unmatched After-Tax
          Contributions, and then matched After-Tax Contributions and Company
          Matching Contributions (in equal amounts) of Highly Compensated
          Employees which exceed the ACP limitation shall be reduced, beginning
          with the highest contribution percentage and then continuing with each
          next lower percentage as the ceiling declines, as follows:

          (i)  Any amount reduced from After-Tax Contributions (including
               recharacterized contributions) shall be distributed with related
               earnings to the Employee to whom it applies.

          (ii) Any amount reduced from Company Matching Contributions shall be
               distributed, with related earnings, to the extent vested, to the
               Employee to whom it applies.

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

                                       22
<PAGE>
 
          In the event excess deferrals are returned to a Highly Compensated
          Employee whose contributions and Compensation were aggregated with
          other family members for purposes of the ACP test in Section 4.3, such
          returned amounts shall be returned to each family member in the same
          proportion that his or her contributions and Compensation bears to
          total contributions and Compensation of the family member group.

     (e)  Contributions in Excess of the Aggregate Limit
          ----------------------------------------------

          In the event contributions exceed the Aggregate Limit (as defined in
          Section 4.4), Participant unmatched After-Tax Contributions, then
          unmatched Before-Tax Contributions, then matched After-Tax
          Contributions, then matched Before-Tax Contributions shall be
          considered excess contributions pursuant to (c) or (d) above, as
          applicable, and shall be returned to Highly Compensated Employees
          pursuant thereto.

     (f)  Adjustment for Income
          ---------------------

          An Excess Deferral, ADP excess contribution or ACP excess contribution
          distributed to a Participant shall be adjusted for income or loss for
          the calendar year using the method described in Section 5.3.

     (g)  Vesting Exception
          -----------------

          Notwithstanding the vesting provisions of Section 8, a Participant
          shall not have a nonforfeitable right to excess Company contributions
          which are returned or adjusted pursuant to this Section 4.6.

4.7  Recharacterization of Excess Before-Tax Contributions
     -----------------------------------------------------

     (a)  Before-Tax Contributions made to the Plan that exceed the limitations
          of Section 3.1(b) (dollar limitation) or Section 3.4 (ADP test) in the
          discretion of the Committee for each Plan Year may be recharacterized
          as After-Tax Contributions rather than distributed to Participants as
          provided in Section 4.6(b) and (d) above.

     (b)  Recharacterization may be combined with a distribution to correct the
          excess.  If part of the excess is recharacterized, the distribution
          necessary for correction shall be reduced by the amount
          recharacterized and related income.  Income related to a
          recharacterized excess shall not be treated as an amount
          recharacterized, but shall remain attributed to the applicable Before-
          Tax Contribution Account.  Recharacterized Before-Tax Contributions
          will be eligible for Company Matching Contributions.

     (c)  An amount recharacterized shall be treated as the Company contribution
          for purposes of Sections 9 and 10.  An amount recharacterized before
          January 1, 1988 shall be treated as an After-Tax Contribution for
          purposes of withdrawal under Section 7.5(b).  Amounts recharacterized
          after January 1, 1988 will be

                                       23
<PAGE>
 
          treated as Before-Tax Contributions for purposes of hardship
          withdrawal under Section 7.5(c).  Recharacterized amounts shall be
          treated as Before-Tax Contributions for purposes of determining
          Compensation.

5.3  Allocation of Trust Fund Earnings and Losses to Participant Accounts
     --------------------------------------------------------------------

     (a)  Fixed Income Fund, Balanced Fund, Core Equity Fund, Aggressive Equity
          ---------------------------------------------------------------------
          Fund, and International Fund
          ----------------------------

          As of each Valuation Date, any increase or decrease in the fair market
          values (including interest, dividends, realized and unrealized gains
          and losses) of the Fixed Income Fund, the Balanced Fund, the Core
          Equity Fund, the Aggressive Equity Fund, and the International Fund
          shall be allocated among the Participant Accounts on the basis of the
          interests in the particular Fund held in the Accounts as of the
          immediately preceding Valuation Date, adjusted for contributions,
          distributions and transfers made since that date, in accordance with
          administrative procedures established by the Committee.

          Notwithstanding the foregoing, in the event a Terminated Participant
          has received a distribution of his or her vested Account balances, the
          nonvested portion of his or her Accounts shall not be credited with
          Trust Fund earnings and losses pursuant to this section after the
          Valuation Date which coincides with or next precedes the date of
          Termination of employment.

     (b)  Company Stock Fund
          ------------------

          Company Matching Contributions and Supplemental Company Contributions
          shall be invested solely in the Company Stock Fund, and may be made in
          cash or shares of Company Stock.  The Trustee shall apply cash
          contributions to the purchase of Company Stock over a period of time
          as directed by the Committee.  As of each Valuation Date, each
          Participant's Company Matching Contribution Account (and Supplemental
          Company Contribution Account, if applicable) shall be credited with a
          number of shares of Company Stock that represent the Company Matching
          Contribution (and Supplemental Company Contribution, if applicable)
          made on the Participant's behalf, based on the average price of the
          shares contributed to the Plan and purchased by the Trustee since the
          Valuation Date.

          If a Participant elects to transfer amounts in his or her Accounts
          invested in the SpaceLabs Stock Fund to the Company Stock Fund, the
          Trustee shall apply the transferred cash amount to the purchase of
          Company Stock as described in the preceding paragraph.  As of the next
          following Valuation Date, the Participant's Accounts will be credited
          with a number of shares of Company Stock that represent the amount
          transferred to the Company Stock Fund, based on the average price of
          the shares purchased by the Trustee since the effective date of the
          transfer.

          As of each Valuation Date, dividends and other distributions received
          on Company Stock held in the Company Stock Fund may be reinvested in
          Company Stock or held in short-term cash investments.  The
          Participants' Accounts shall be credited with a proportionate amount
          of shares and/or cash determined on the

                                       27
<PAGE>
 
          basis of the number of shares in each Participant's Accounts on the
          record date of such distribution.

     (c)  SpaceLabs Stock Fund
          --------------------

          If a Participant elects to transfer amounts in his or her Accounts
          invested in the SpaceLabs Stock Fund to other funds as provided in
          Section 5.2(f), the transfer shall be made in cash.  The cash value of
          common stock of SpaceLabs Medical, Inc. that is so transferred shall
          be based on the actual proceeds from the sale of the stock.

          As of each Valuation Date, dividends and other distributions received
          on common stock of SpaceLabs Medical, Inc. held in the SpaceLabs Stock
          Fund shall be reinvested in common stock of SpaceLabs Medical, Inc. or
          held in short term cash investments.  The Participant's Accounts shall
          be credited with a proportionate number of shares and/or cash
          determined on the basis of the number of shares in each Participant's
          Accounts on the record date of such distribution.

5.4  Valuation of the Trust Fund
     ---------------------------

     The fair market value of the Trust Fund shall be determined as of each
     Valuation Date and at any time specifically requested by the Plan
     Administrator.  Any portion of the Trust Fund held under an insurance
     contract or bank investment contract in which asset values are only
     maintained on a book value basis shall have that portion of the Trust Fund
     valued at book value rather than market value.

5.5  Account Statements
     ------------------

     Each Participant shall be provided with a statement of his or her Accounts
     under the Plan showing the Account values on dates determined by the
     Committee, but not more frequently than each calendar quarter.  If within
     thirty (30) days after the statement is mailed the Participant makes no
     objection to the statement, it shall become binding and conclusive on the
     Participant and any Beneficiary.

                          INVESTMENT OF CONTRIBUTIONS


6.1  Optional Funds
     --------------

     Each Participant, at the time the Participant elects to participate in the
     Plan, shall direct that the Participant's After-Tax Contributions to the
     Plan and the Before-Tax Contributions made on the Participant's behalf be
     invested (in multiples of 10%) in any one of the following investment
     funds, or in any combination of the funds:

     Contributions and After-Tax Contributions, and a separate investment
     election shall be made with respect to Rollover Contributions.



6.2  Selection of Investment Funds
     -----------------------------

     The selection of an investment option pursuant to this Section 6 is the
     sole responsibility of each Participant.  The Trustee, the Committee, any
     Participating Company, or any of their officers or supervisors are not
     empowered to advise a Participant as to the manner in which his Account
     should be invested.  The fact that a security is available to Participants
     for investment under the Plan shall not be construed as a recommendation
     for the purchase of that security, nor shall designation of any option by
     the Participant impose any liability on a Participating Company, its
     directors, officers or employees, the Trustee, the Committee or any
     Participant in the Plan.

     Subject to any applicable provision of law, each Participant assumes all
     risks connected with any decrease in the market value of any securities in
     the funds and such funds shall be the sole source of payments to be made
     under the Plan.

                         BENEFITS AND FORMS OF PAYMENT


7.1  Eligibility for Benefits
     ------------------------

     A Participant shall be eligible to receive a distribution of his or her
     Accounts, to the extent vested, upon retirement, becoming Disabled, or upon
     Termination of employment with the Company and any Affiliated Companies.  A
     Participant's Beneficiary shall be eligible to receive a distribution of
     the balance of the Participant's accounts upon the death of the
     Participant.

     Notwithstanding the foregoing, in the event a Participant again becomes an
     Employee before benefits commence, he or she shall no longer be eligible to
     receive a distribution.

     Also notwithstanding the foregoing, with respect to an individual who was a
     Participant in this Plan between June 25 and December 31, 1992 and whose
     Account balances were transferred to the SpaceLabs Medical, Inc. Incentive
     Savings and Stock Ownership Plan ("SpaceLabs Plan") in connection with the
     spin-off of that plan from this Plan, such individual's Account balances as
     of the date of such transfer shall be payable from the SpaceLabs Plan and
     shall not be payable from this Plan.

7.2  Time of Benefit Commencement
     ----------------------------

     (a)  Benefit Commencement
          --------------------

          Benefits shall be paid as soon as practical following a request for
          benefit commencement and determination of the amount of payment under
          subparagraph (b) below.  Participants and Beneficiaries may request
          benefit commencement as described below.

          (i)  Participant
               -----------

               A Participant who is eligible for benefits may request benefit
               commencement by written notice to the Committee.  Benefits may
               commence at any time following Termination and on or before the
               April 1 following the year in which the Participant attains or
               would have attained age 70-1/2.   If such a Participant fails to
               request benefit commencement, he or she shall be deemed to have
               requested that benefits commence on the April 1 following the
               year in which the Participant attains age 70 1/2.

          (ii) Beneficiary
               -----------

               A Beneficiary who is eligible for benefits may request benefit
               commencement by written notice to the Committee.  Benefits for a
               spouse

                                       32
<PAGE>
 
               Beneficiary may commence at any time after the Participant's
               death and on or before the Participant's Normal Retirement Date,
               calculated as if he or she had survived.  If a spouse Beneficiary
               fails to request benefit commencement, benefits shall commence on
               or immediately preceding the April 1 following the calendar year
               in which the Participant would have attained age 65 if he or she
               had survived.

               Benefits for a non-spouse Beneficiary shall not be contingent on
               receipt of a written request for benefit commencement, but shall
               commence as soon as practical following the end of the month
               which coincides with or next follows the date of the
               Participant's death.

     (b)  Amount of Payment
          -----------------

          With the exception of amounts invested in the Company Stock Fund or
          the SpaceLabs Stock Fund, the amount distributed shall be based on the
          Account balance determined as of the last Valuation Date on which the
          Accounts were valued, adjusted for earnings and losses since such
          date.

          If stock is distributed from the Company Stock Fund or the SpaceLabs
          Stock Fund, the number of shares distributed shall be the number of
          whole shares in the Participant's Account as of the date of
          distribution, with any fractional shares paid in cash based on the
          average of the high and low selling price on the day preceding the
          date of distribution.

          If stock held in the Company Stock Fund or the SpaceLabs Stock Fund is
          distributed in cash, the amount distributed shall be based on the
          price at which the stock held in the Participant's Accounts is sold,
          or, if the stock held in the Participant's Accounts is not sold, the
          average of the high and low selling price on the day preceding the
          date of distribution.

          The value of a distribution of the portion of the Participant's
          Accounts invested in the Company Stock Fund or SpaceLabs Stock Fund
          that is invested in cash shall be based on the Account balance
          invested in cash as of the last Valuation Date on which the Accounts
          were valued.

     (c)  Small Benefits
          --------------

          Notwithstanding any election to commence benefits or lack thereof, the
          Committee shall distribute a benefit which is $3,500 or less at the
          time benefits commence, in a lump sum as soon as practical following
          Termination of employment, death or becoming Disabled, without
          Participant or Beneficiary consent.

          filed with the Committee no more than 30 days after the Participant's
          death to receive payment in the form of five annual installments, to
          be paid in cash only.  A spouse Beneficiary may elect five, ten or
          fifteen annual installments; provided, however, that such installments

          The amount distributed shall be based on the value of the

          that the amount of a withdrawal representing shares held in the
          Company Stock Fund or SpaceLabs Stock Fund shall be based on the price
          at which the shares are sold, or, if the shares are not sold, the

          withdrawal, the remainder of the withdrawal shall be made from the
          Participant's Accounts in the other funds in an order of preference
          designated by the Participant.  Should the Participant fail to

     (d)  Determination of Necessity
          --------------------------

          A distribution shall be deemed to be necessary to satisfy an expense
          described in 7.6 above if both of the following requirements are
          satisfied:

          (i)  the distribution is not in excess of the amount of such expense
               (including any excise tax or income tax liability arising from
               the distribution); and

          (ii) the Participant has obtained all distributions (other than

     (e)  Other Requirements
          ------------------

          A hardship distribution shall be deducted first from the category of
          available amounts described in (a)(ii) herein and then from the

          withdrawal.  Following a 12-month suspension, the Participant may
          resume contributions pursuant to Section 3.2. In addition, the
          Participant may not make a Before-Tax Contribution to the Plan or any
          other Section 401(k) plan maintained by the Company for the
          Participant's taxable year immediately following the taxable year of
          the hardship withdrawal, in excess of Before-Tax Contributions
          allowable in Section 3.1 for the next taxable year less the amount of
          such Participant's Before-Tax Contributions for the taxable year of
          the hardship withdrawal.

          Notwithstanding the foregoing, a Participant whose contributions have
          been suspended for twelve months due to a hardship withdrawal shall be
          deemed to be an Eligible Employee for purposes of the ADP test in

          reasonable period (at least thirty (30) but not more than ninety (90)
          days) prior to the Participant's or Beneficiary's Annuity Starting
          Date; provided, however, that a Participant or Beneficiary may waive
          in writing the thirty (30) day period with respect to a distribution
          of small benefits equal to $3,500 or less.

                                   SECTION 8

                                    VESTING


8.1  Vesting
     -------

     (a)  Participant Before-Tax Contribution Account
          -------------------------------------------

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

     (b)  Company Matching and Supplemental Contribution Accounts
          -------------------------------------------------------

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

<TABLE>
<CAPITION>

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

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

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

                              X = P(AB+D) - D;

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

                                       41
<PAGE>
 
          Notwithstanding the foregoing, this formula does not apply if the
          Participant has repaid the prior distribution pursuant to Section
          8.3(b).  Also, the formula does not apply if the prior distribution
          may not be repaid because the Participant has incurred five or more
          consecutive one year Periods of Severance, or because five years or
          more have elapsed since the date of reemployment.

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

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

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

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

8.3  Reemployment
     ------------
 
     (a)  Periods of Service
          ------------------

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

     (b)  Repayment
          ---------

          If a Participant forfeited a portion of his or her Company Matching
          and Supplemental Contribution Accounts upon termination and he or she
          returns to Service after receiving a distribution and prior to
          incurring a five-year Period of

                                       42
<PAGE>
 
          Severance, the Participant may elect to repay the amount previously
          distributed from his or her Company Matching and Supplemental
          Contribution Accounts.  Such Participant may elect to repay his or her
          prior distribution before five years after the date of reemployment.
          The forfeited amount shall be restored upon such repayment pursuant to
          Section 8.2.  Amounts repaid shall be 100% vested and shall be
          invested in accordance with Section 6.3.  Such amounts shall be held
          in the Participant's After-Tax Contribution Account if they are repaid
          with after-tax amounts, and shall be held in the Participant's Pre-Tax
          Contribution Account if they are repaid with pre-tax amounts
          transferred or rolled over from another qualified plan or IRA.

     (c)  Restoration of Forfeitures
          --------------------------

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

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

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

                                       43

                                   SECTION 9

                          LIMITATION ON CONTRIBUTIONS


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

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

     (a)  Primary Rule
          ------------

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

     (b)  Annual Additions Defined
          ------------------------

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

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

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

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

     (c)  Cost-of-Living Adjustment
          -------------------------

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

     (d)  Remedy
          ------

          If for any Plan Year the Annual Additions exceed the foregoing
          limitations because of a reasonable error in determining the amount of
          a Participant's Before-Tax Contributions, the Plan Administrator shall
          distribute the amount of Before-Tax Contributions in excess of the
          limits.  If the Annual Additions exceed the

                                       44
<PAGE>
 
          limits for any other reason, the Company shall allocate the excess to
          a suspense account.  The suspense account shall be credited with
          investment earnings and losses as of each Valuation Date in the same
          manner as Participant Accounts pursuant to Section 5.3.  Such suspense
          account is for accounting purposes only and shall remain in the Trust
          Fund to be reallocated as provided below.  Contents of the suspense
          account shall be allocated to the affected Participant's Account in
          subsequent years when that can be done without exceeding the
          limitations of this Section 9.1.  So long as any amount remains in the
          suspense account, the Company shall not contribute to the Plan any
          amount which would cause an additional allocation to the suspense
          account.  In the event the Participant ceases to be a Participant when
          any amount remains in a suspense account, such amount shall be
          reallocated to active Participants as of the end of the Plan Year
          following the calendar year in which he or she ceases to be a
          Participant.  In the event the Plan terminates before any amount
          remaining in the suspense account has been fully allocated to
          Participant Accounts, the balance of the suspense account shall be
          distributed to the Company.

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

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

     (a)  Primary Rule
          ------------

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

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

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

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

                                       45
<PAGE>
 
          (2)  The defined contribution plan fraction for any year is equal to
               the quotient of (i) divided by (ii) below expressed as a
               fraction:

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

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

     (b)  Remedy
          ------

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

                                   SECTION 10

                              TOP HEAVY PROVISIONS

10.1 Scope
     -----

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

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

     (a)  Top Heavy
          ---------

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

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

     (b)  Super Top Heavy
          ---------------

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

     (c)  Determination Date
          ------------------

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

                                       47
<PAGE>
 
     (d)  Valuation Date
          --------------

          "Valuation Date" means, for purposes of determining Top Heaviness, the
          Determination Date instead of the meaning set forth in Section 1.

     (e)  Aggregate Account
          -----------------

          "Aggregate Account" means, with respect to a Participant, the sum of:

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

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

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

     (f)  Present Value of Accrued Benefits
          ---------------------------------

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

     (g)  Key Employee
          ------------

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

          (i)  an officer of the Company whose annual aggregate Compensation
               from the Affiliated Companies exceeds 50% of the dollar
               limitation under Code Section 415(b)(1)(A) ($56,111 for the Plan
               Year ending in 1992), provided that no more than 50 Employees
               shall be considered officers, or if less, the greater of 10% of
               the Employees or 3,

          (ii) one of the ten Employees owning the largest interest in the
               Company who owns more than a 0.5% interest of the Company, and
               whose annual aggregate Compensation from the Affiliated Companies
               exceeds the dollar limitation under Section 415(c)(1)(A) of the
               Code ($30,000 for the Plan Year ending in 1992).

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

                                       48
<PAGE>
 
          (iv) an Employee who owns more than 1% of the Company with annual
               aggregate Compensation from the Affiliated Companies that exceeds
               $150,000.

     (h)  Aggregation Group
          -----------------

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

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

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

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

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

     (a)  General Rule
          ------------

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

                                       49
<PAGE>
 
          that Plan Year under any defined contribution plans sponsored by the
          Affiliated Companies.

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

     (b)  Special Two Plan Rule
          ---------------------

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

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

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

     If this Plan is Top Heavy, but is not Super Top Heavy, the above referenced
     fractions shall remain unchanged provided the Company makes an extra
     minimum allocation for non-Key Participants.  The extra allocation (in
     addition to the minimum contribution set forth in Section 10.3) shall equal
     at least one percent (1%) of a non-Key Participant's compensation (or
     2-1/2% if Section 10.3(b) applies).

10.5 Vesting
     -------

     For any Top Heavy Plan Year, a Participant's Accounts shall remain subject
     to the vesting provisions in Section 8.1.

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

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

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

          Notwithstanding the above, any Participant or Beneficiary who is to
          receive a distribution from the Plan in shares of Company Stock may,

          make a revocable election that such stock be issued jointly (with the
          right of survivorship) to him and his spouse; provided, however, that
          no such election shall be effective until the Participant's or
          Beneficiary's spouse files a written acknowledgement with the
          Committee, in accordance with Treasury Regulations (S)1.401(a)-
          13(e)(2), stating that such spouse has no enforceable right in, or to,

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

     (d)  Governing Law
          -------------

          This Plan shall be construed in accordance with applicable federal law
          and the laws of the State of Washington.

     (e)  Disclosure to Participants
          --------------------------

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

     (f)  Income Tax Withholding Requirements
          -----------------------------------

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

     (g)  Severability
          ------------

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

     (h)  Facility of Payment
          -------------------

          In the event any benefit under this Plan shall be payable to a person
          who is under legal disability or is in any way incapacitated so as to
          be unable to manage his or

                                       56
<PAGE>
 
          her financial affairs, the Committee may direct payment of such
          benefit to a duly appointed guardian, committee or other legal
          representative of such person or in the absence of a guardian or legal
          representative, to a custodian for such person under a Uniform Gift to
          Minors Act or to any relative of such person by blood or marriage, for
          such person's benefit.  Any payment made in good faith pursuant to
          this provision shall fully discharge the Company and the Plan of any
          liability to the extent of such payment.

     (i)  Correction of Errors
          --------------------

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

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

     (j)  Missing Persons
          ---------------

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

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

          Prior to forfeiting any Account, the Company shall attempt to contact
          the Participant or Beneficiary by return receipt mail at his or her
          last known address according to the Company's records, and by the
          letter forwarding services offered through the Internal Revenue
          Service, or the Social Security Administration, or such other means as
          the Committee deems appropriate.

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

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

                                       57
<PAGE>
 
       (a)  relates to the provision of child support, alimony payments or

            dependent of a Participant;

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                           AMENDMENT AND TERMINATION


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

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

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

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

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

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

                                       60
<PAGE>
 
     directors of the Participating Company, with the consent of the Board, may
     merge such trust into the Trust under the Plan and thereupon all employees
     of such Participating Company and employees of other Participating
     Companies who had a vested interest in the merged trust shall automatically
     become Participants in the Plan but solely for the purposes of investing
     the amounts so transferred and distributing such amounts to such employees
     as hereinafter set forth in the Plan.  The amounts so transferred on behalf
     of each such employee shall be invested in such funds as he shall direct,
     under the provisions of Section 6.1.  Any amounts transferred under this
     paragraph shall constitute "Special Contributions."  Under no circumstances
     will any Participating Company be required or permitted to make company
     matching contributions to the Plan based on Special Contributions.  Special
     Contributions and any earnings thereon may not be withdrawn by a
     Participant until such time as the Participant ceases to be an Employee of
     a Participating Company on account of death, retirement, or other voluntary
     or involuntary termination of employment; provided, however, that a full
     withdrawal of such Special Contributions and earnings may be made by a
     Participant after attainment of age 59-1/2, if he shall at the same time
     make a full withdrawal of all his interest in this Plan.  Subject to the
     foregoing, all such distributions shall be made in accordance with the
     provisions of this Plan.

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

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

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

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

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

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

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

                                       61
<PAGE>
 
     shall be made, in the discretion of the Committee, either wholly or in part
     by the purchase of non-transferable annuity contracts or by lump-sum
     payments.

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

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

                                       62

                                    FUNDING

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

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

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

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

13.3 Trustee
     -------

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

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

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

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

     (b)  is either

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

          (ii) is a bank; or

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

                                       63
<PAGE>
 
     (c)  has acknowledged in writing that he, she or it is a fiduciary with
          respect to the Plan.

                                   SECTION 14

                                  FIDUCIARIES


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

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

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

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

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

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

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

     Each participant in the Retirement Plan whose benefits thereunder are
     limited by (a) the dollar limitation on compensation that may be taken
     into account under the plan of Section 401(a)(17) of the Code and/or (b)
     the benefits limitations of Section 415 of the Code (including, without
     limitation, the maximum benefit payable under Section 415(b)(1), the
     actuarial reduction for early retirement of Section 415(b)(2)(C), the
     reduction for limited service or participation of Section 415(b)(5), and
     the combined limits of Section 415(e)) shall become a Participant in this
     Plan.  Participation shall begin as of the later of the effective date of
     the Plan or the last day of the first Plan Year in which the individual's
     accrued benefit under the Retirement Plan is limited by Sections
     401(a)(17) or 415 of the Code.

4.2  Retirement Plan Benefit

     For purposes of determining participation in and benefits under this Plan,
     the benefit to which an individual is entitled under the Retirement Plan

                                    BENEFITS


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

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

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

     For all years subsequent to calendar year 1993, the supplemental pension
     benefits for a Participant who is not the Chief Executive Officer or one
     of the other four most highly compensated executive officers of the
     Company who were serving as executive officers at the end of the last
     completed fiscal year, as specified in Item 402 of Regulation S-K of the
     Securities and Exchange Act of 1934 and reported in the Company's proxy
     statement for the applicable year (the "Five Highest Compensated
     Officers") shall be determined, as to such years subsequent to 1993, by
     disregarding any Earnings which are in excess of the average of the
     Earnings of the Five Highest Compensated Officers for such year.

5.2  Other Supplemental Pension Benefits
     -----------------------------------

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

5.3  Death Benefits
     --------------

     Upon the death of a Participant prior to Retirement, the Company shall pay
     to the Surviving Spouse (if any) of such Participant a death benefit which
     when combined with the death benefit which he or she is entitled to
     receive under the Retirement Plan shall equal the death benefit that would
     have been payable to the Surviving Spouse had the Retirement Plan's
     benefit provisions been applied as provided in Section 5.1 or 5.2 above,
     as applicable.

                              PAYMENT OF BENEFITS


6.1  Payment of Benefits
     -------------------

     Upon the Retirement or Disability of a Participant, the Company shall pay
     to such Participant the benefit provided in Section 5 in the form of a
     monthly annuity payable from the commencement date as provided in Section
     6.2 to the first of the month preceding death.  Upon the death of a
     Participant prior to commencement of benefits under this Plan, the Company
     shall pay to the Surviving Spouse of such Participant one half of the
     benefit provided in Section 5 in the form of a monthly annuity payable
     from the commencement date as provided in Section 6.2 to the first of the
     month preceding the death of the Surviving Spouse.

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

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

6.2  Commencement of Payment
     -----------------------

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

                               GENERAL PROVISIONS


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

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

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

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

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

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

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

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

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

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

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

7.6  ERISA Exemption
     ---------------

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

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

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

   THIS TRUST AGREEMENT ("Trust Agreement") is known as the Advanced Technology
Laboratories, Inc. Incentive Savings and Stock Ownership Plan Trust Agreement,
and was formerly known as the Amended and Restated Trust Agreement for Defined
Contribution Plans By and Between Westmark International Incorporated and First
Interstate Bank of Washington, N.A.

   Westmark International Incorporated established the Westmark International
Incorporated Incentive Savings and Stock Ownership Plan, and an associated trust
fund ("Trust Fund") governed by the Trust Agreement for Defined Contribution
Plans, effective January 2, 1987, in connection with the distribution of shares
of Westmark International Incorporated to shareholders of Squibb Corporation.

   The Plan was amended and restated effective January 1, 1989, and the Trust
Agreement was amended and restated effective February 1, 1991.

   The corporate name of Westmark International Incorporated was changed to
Advanced Technology Laboratories, Inc. effective June 26, 1992.  The Plan was
amended and restated, and the name of the Plan was changed to the Advanced
Technology Laboratories, Inc. Incentive Savings and Stock Ownership Plan. The
Trust Agreement is hereby renamed and restated effective June 26, 1992.

   Advanced Technology Laboratories, Inc. ("Company") and the undersigned
trustee ("Trustee") intend that the Plan and Trust will comply with the Employee
Retirement Income Security Act of 1974, as amended, Section 401(a) of the
Internal Revenue Code of 1986, as amended, and related Treasury Regulations and
that the Trust qualifies as a tax-exempt trust under Section 501(a) of the Code.

   The Plan is administered by a committee appointed by the Company (the
"Committee").

   The Company and the Trustee now enter into this Trust Agreement on the
following terms:

                                   ARTICLE 1


1.1  Trustee Responsibility
     ----------------------

     The Trustee shall hold the assets of and collect the income and make
     payments from the Trust Fund, all as hereinafter provided.  Subject to the
     conditions and limitations set forth herein, the Trustee shall be
     responsible for the property received by it as Trustee, but, except as
     otherwise specifically agreed to by the Trustee, shall not be responsible
     for the administration of any Plan (including without limitation the
     determination of Plan participation rights of employees of any Company and
     the determination of benefits of members of any Plan) or for those assets
     of any Plan which have not been delivered to and accepted by the Trustee;
     provided, however, that the Trustee shall maintain the participant
     accounting for a plan if so directed by the Company.  The Trustee shall
     not have any authority or obligation to determine the adequacy of or to
     enforce the collection from the Company or from any Company of any
     contribution to the Trust Fund.  Except to the extent that assets of the
     Trust Fund have been deposited in a collective investment fund maintained
     by the Trustee or that the Trustee has been designated as an Investment
     Manager (as defined in Article II hereof), the Trustee shall not be
     responsible, directly or indirectly, for the investment or reinvestment of
     the assets of the Trust Fund, which investment and reinvestment shall be
     the sole responsibility of the Company unless otherwise delegated by the
     Company as provided in ARTICLE II hereof.

1.2  Payments from Trust Fund
     ------------------------

     Subject to the provisions of Section 9.5, the Trustee shall make payments
     from the portion of the Trust Fund attributed to each Plan as directed by
     the respective Committee which administers such Plan.  Such Committee, in
     directing the Trustee to make payments, shall follow the provisions of the
     Plan so that it shall be impossible for any part of the Trust Fund to be
     used for, or diverted to, purposes other than for the exclusive benefit of
     employees covered under such Plan or their beneficiaries except to the
     extent permitted by this Agreement or any Plan.  Subject to the foregoing,
     each such Committee may direct such payments to be made to any person,
     including any member of such Committee, or to the applicable Company, or
     to any paying agent designated by a Company, in such amounts and in such
     form (including, without limitation, shares of Company stock and shares of
     SpaceLabs Medical, Inc. Stock) as the Committee shall direct.  The Trustee
     shall have no responsibility with respect to any payment made, pursuant to
     such a direction, to any Company, any Committee or any member thereof, to
     any paying agent, or to any other person, and any payment so made shall be
     held in trust by the recipient until disbursed in accordance with the
     Plan.  Each direction of each such Committee shall be in writing and shall
     be deemed to include a certification that any payment directed thereby is
     one which the Committee is authorized to direct, and the Trustee may
     conclusively rely on such certification without further investigation. 
     Unless otherwise specified by the Committee, payments by the Trustee may
     be made by its check to the order of the payee and mailed to the payee at
     the address last furnished to the Trustee by the

                                       2
<PAGE>
 
     Committee or by the payee, or, if no such address has been so furnished,
     to the payee in care of the Company.

     The establishment of the Trust Fund created by this Agreement shall not be
     considered as giving any Plan member or any other person any legal or
     equitable rights as against the Company, any Company, any Committee, the
     Trustee or the property, whether corpus or income, of the Trust Fund
     unless such right is specifically provided for in this Agreement or the
     applicable Plan, nor shall it be considered as giving any Plan member or
     other employee the right to continue in the service of a Company in any
     capacity.

1.3  Powers of Trustee

         reasonable compensation and expenses of each such subtrustee.  Any
         such subtrustee, upon being appointed, shall act with such one or more
         or all of the powers, authorities, discretions, duties and functions
         of the Trustee under this Article I as shall be designated in the

     No person dealing with the Trustee shall be required to take any notice of
     this Agreement, but all persons so dealing shall be protected in treating
     the Trustee as the absolute owner with full power of disposition of all
     the moneys, securities and other property of the Trust Fund, and all
     persons dealing with the Trustee are released from inquiry into the
     decisions or authority of the Trustee and from seeing to the application
     of the moneys, securities or other property paid or delivered to the
     Trustee.

1.4  Securities; Property
     --------------------

     Wherever used in this Agreement the term "securities" shall include bonds,
     mortgages, notes, obligations, warrants and stocks of any class (including
     stocks issued by the Company to the extent authorized by the Plan),
     certificates of participation or shares of any mutual investment company,
     trust or fund, and such other evidences of indebtedness and certificates
     of interest as are usually referred to by the term "securities," and the
     term "property" shall include real, personal and mixed property, tangible
     or intangible, of any kind and wherever located, including without
     limitation securities, depository accounts in the banking department of
     the Trustee, and interests in any fund which has been or may be created
     and administered by the Trustee, or by an Investment Manager, for the
     collective investment of the property of employee benefit trusts.  The
     investment of the assets of the Trust Fund in any such depository account
     or collective investment fund is hereby specifically authorized.  To the
     extent that property of the Trust Fund is so invested in a collective
     investment fund, the declaration of trust pertaining to such collective
     investment fund and the trust thereby created shall be a part of this
     Agreement and of each Plan whose assets are so invested; and for the
     purposes of any valuation of the Trust Fund or any valuation of the
     interest or of the account of any employee or beneficiary under a Plan,
     the interest of the Trust Fund in such collective investment fund shall be
     valued at the times and in the manner prescribed by the declaration by
     which such collective investment fund was created.

                                       5

1.5  Proxies
     -------

     Subject to the provisions of Section 1.6, in order to permit the Company
     or an Investment Manager, as the case may be, to make timely and informed
     decisions regarding the management of those assets in the Trust Fund
     subject to its respective control, the Trustee shall forward to the
     Company or each such Investment Manager, as the case may be, for
     appropriate action any and all proxies, proxy statements, notices,
     requests, advice or other communications received by the Trustee (or its
     nominee) as the record owner of such assets.

1.6  Company Securities
     ------------------

     Notwithstanding anything herein to the contrary, if a Plan provides that
     the Trustee shall exercise voting rights with respect to shares of the
     stock of the Company at the direction of the Committee or the members of
     the Plan, the Trustee shall utilize its best efforts to deliver, or cause
     to be delivered, to the Committee or the members of the Plan, as the case
     may be, a copy of all proxies, notices and other information which the
     Company generally distributes to the shareholders of the Company.  The
     Trustee shall establish such procedures for the collection of the
     instructions of the Committee or Plan members on the voting of such
     Company stock as it shall determine to be appropriate.  The Trustee shall
     vote specifically in accordance with the Committee's or each member's
     instructions, as applicable, to the extent of the number of whole shares
     designated to be voted by the Committee or allocated to such member's
     account.  Any Company stock designated to be voted by the Committee or
     allocated to members' account for which no signed voting-direction
     instrument is timely received from the Committee or any member and any
     other remaining unallocated shares held in the Trust Fund shall be voted
     by the Trustee for or against the proposals submitted, in the same
     proportion as shares of Company stock held in the Trust Fund for which
     voting directions have been timely received; provided, however, that  if
     the Plan is a tax credit employee stock ownership plan within the meaning
     of Section 409 of the Code, the Trustee shall not vote any allocated
     shares with respect to which no signed voting-direction instrument has
     been timely received.

     If a Plan provides that, in the event of a tender offer or exchange offer
     by any person (including the Company) for any or all shares of Company
     stock held in the Trust Fund, each member under the Plan or the Committee
     shall have the right to instruct the Trustee as to the manner in which to
     respond with respect to any or all shares of stock allocated to such
     member's account or designated to be under the direction of the Committee,
     the Trustee shall act with respect to such stock specifically in
     accordance with the written instructions submitted by the Plan members or
     the Committee, as applicable, to the extent of the number of whole shares
     allocated to such member's account or designated to be under the direction
     of the Committee.  To the extent such materials are not distributed to the
     members by the Company, the Trustee shall utilize its best efforts to
     distribute or cause to be distributed to each member and/or the Committee
     substantially the same information as may be distributed to the
     stockholders of the Company in connection with such offer.  The Trustee
     shall establish such procedures for the collection of members'
     instructions with respect to the disposition of such Company stock as it
     shall deem appropriate.

                                       6
<PAGE>
 
     Any such Company stock with respect to which written instructions have not
     been timely received by the Trustee and any other remaining unallocated
     shares held in the Trust Fund shall not be voted by the Trustee.

     For purposes of this Section 1.6, "shares of Company stock" shall refer to
     shares of Advanced Technology Laboratories, Inc. stock, and to shares of
     SpaceLabs Medical, Inc. stock.

     The Trustee shall not incur any liability on account of actions taken by
     the Trustee in accordance with directions received pursuant to this
     Section 1.6.

                                   ARTICLE 2


2.1  Investment Managers
     -------------------

     The Company may from time to time appoint one or more Investment Managers,
     as that term is defined in the Employee Retirement Income Security Act of
     1974, as from time to time amended (hereinafter referred to as the "Act"),
     to manage (including the power to acquire and dispose of) any portion of
     the Trust Fund and, with respect to such portion, to direct the Trustee
     with respect to effecting investment transactions on behalf of the Trust
     Fund and exercising such other powers as may be granted to Investment
     Managers hereunder.  The Company shall give prompt written notice to the
     Trustee of any such appointment, upon which the Trustee shall rely until
     it receives from the Company written notice of the termination of such
     appointment.  Any such Investment Manager may direct the Trustee to invest
     and reinvest through the medium of any collective investment fund
     maintained by the Investment Manager or by the Trustee which is exempt
     from tax under the provisions of Section 501(a) of the Code and, during
     such period of time as an investment through any such medium shall exist,
     the declaration of trust of such fund shall constitute a part of this
     Agreement.  In each case where such an appointment is made, the Company
     shall determine the assets of the Trust Fund (which may include all or any
     portion of one or more of the Investment Funds established pursuant to
     Section 2.2) to be allocated to the Investment Manager from time to time
     and shall issue appropriate instructions to the Trustee with respect
     thereto.  The Trustee shall not be liable for the acts or omissions of
     such Investment Manager, shall be under no duty to question any direction
     of an Investment Manager with respect to the portion of the Trust Fund
     managed by such Investment Manager, to review any securities or property
     held in such portion, to make any suggestions with respect to the
     investment and reinvestment of such portion, or to evaluate the
     performance of any Investment Manager, and shall be fully protected in
     acting in accordance with the directions of an Investment Manager or for
     failing to act in the absence of such directions.

2.2  Investment Funds
     ----------------

     A Committee, from time to time and in accordance with the provisions of
     the Plan, may direct the Trustee to establish one or more separate
     investment accounts (including without limitation insurance company
     contracts or accounts, mutual funds, or collective investment funds) under
     the Plan (each such separate account hereinafter referred to as an
     "Investment Fund").  The Trustee shall transfer to each such Investment
     Fund such portion of the assets of the Plan held in the Trust Fund as the
     Committee directs in accordance with the specific provisions of the Plan. 
     The assets which have been allocated to an Investment Fund shall be
     invested and reinvested in accordance with the provisions of the Plan and
     with such investment guidelines, objectives and restrictions as may be
     established by the Committee for that Investment Fund.  The Trustee shall
     be under no duty to question, and shall not incur any liability on account
     of following any direction of the Committee, nor to review the investment
     guidelines, objectives and restrictions established, or the specific
     investment directions given by the Committee for any Investment Fund, nor
     to make

                                       8
<PAGE>
 
     suggestions to the Committee in connection therewith.  To the extent that
     directions from the Committee to the Trustee represent investment
     elections of the members under the Plan, the Committee and the Trustee
     shall not have any responsibility for such investment elections and shall
     incur no liability on account of investing the assets of the Trust Fund in
     accordance with such directions.

     Unless the Trustee is otherwise directed by the Committee, all interest,
     dividends and other income received with respect to, and any proceeds
     received from the sale or other disposition of securities or other
     property held in an Investment Fund shall be credited to and reinvested in
     such Investment Fund, and all expenses of the Trust Fund which are
     properly allocable to a particular Investment Fund shall be so allocated
     and charged.  Subject to the provisions of the Plan, the Committee may
     direct the Trustee to eliminate an Investment Fund or Funds, and the
     Trustee shall thereupon dispose of the assets of such Investment Fund and
     reinvest the proceeds thereof in accordance with the directions of the
     Committee.

     Pending investment of the Investment Funds in accordance with the
     directions of the Committee, the Trustee may invest assets of the Trust
     Fund, in whole or in part, at any time or from time to time, in
     interest-bearing accounts or certificates of deposit (including depository
     accounts in the banking department of the Trustee which bear a reasonable
     interest rate), treasury bills, commercial paper, money market funds,
     collective investment funds (including any such collective investment fund
     maintained by the Trustee), short-term investment funds or other
     short-term obligations and the investment return thereon shall be
     allocated among the Plan members whose assets have been so invested and
     added to their respective investments in the Investment Funds.

     If, and to the extent, specifically authorized by the Plan, the Committee
     may direct the Trustee to establish an Investment Fund all of the assets
     of which shall be invested in shares of the common stock of the Company,
     and in the event the Committee directs the establishment of such an
     Investment Fund, the Trustee shall invest all amounts allocated to such
     Investment Fund in such shares as promptly as is reasonably practicable. 
     Except as otherwise provided in this Agreement or the Plan, in the event
     that any such shares which are allocable to the account of a Plan member
     are sold, the proceeds thereof shall be invested by the Trustee as
     promptly as is reasonably practicable in the other Investment Funds in
     accordance with the directions of the Committee.  Notwithstanding the
     foregoing, the Trustee shall be under no duty or obligation to invest any
     assets of the Trust Fund in shares of common stock of the Company unless
     such shares constitute "qualifying employer securities" within the meaning
     of Section 407 of the Act and such investment is not prohibited by Section
     406 or 407 of the Act.

2.3  Annuity Contracts
     -----------------

     A Committee may direct the Trustee to receive and hold or apply assets of
     the Trust Fund attributable to its Plan to the purchase of individual or
     group insurance or annuity contracts or policies issued by any insurance
     company and in a form approved by the Committee, including contracts under
     which the contract holder is granted

                                       9
<PAGE>
 
     options to purchase insurance or annuity benefits.  The Trustee shall be
     under no duty to question any direction of the Committee or to review the
     form of any such policies or contracts or of the selection of the issuer
     thereof, or to make suggestions to the Committee with respect to the form
     of such policies or contracts or to the issuer thereof.  The Committee may
     direct the Trustee to exercise or may exercise directly the powers of the
     contract holder under any such policies or contracts, and the Trustee
     shall exercise such powers only upon the direction of the Committee. 
     Notwithstanding anything to the contrary contained in the Plan, the
     Trustee shall be fully protected in acting in accordance with written
     directions of the Committee, and shall be under no liability for any loss
     of any kind which may result by reason of any action taken or omitted by
     it in accordance with any direction of the Committee, or by reason of
     inaction in the absence of written directions from the Committee.  In the
     event that the Committee directs that any moneys or property be paid or
     delivered to the contract holder other than for the benefit of specific
     individual beneficiaries, the Trustee agrees to accept such moneys or
     property as assets of the Trust Fund subject to all the terms hereof.  No
     insurance carrier shall for any purpose be deemed a party to this
     Agreement or be responsible for the validity or sufficiency hereof. 
     Notwithstanding the fact that it may have knowledge of the terms of this
     Trust Fund, the obligations of such insurance carrier shall be measured
     and determined solely by the terms and conditions of the policies or
     contracts issued by it, and there shall be no obligations to any person,
     partnership, corporation, trust or association other than as stated in
     such policies or contracts.  In the event that the Company desires to
     direct the purchase of individual or group insurance or annuity policies
     or contracts for the benefit of some or all of the Plans, the foregoing
     powers and responsibilities of a Committee under this Section 2.3 may be
     exercised by the Company.

2.4  Securities Lending
     ------------------

     The Company may appoint the Trustee as Securities Lending Fiduciary, if
     the Trustee consents to such appointment, to establish, manage and
     administer a securities lending program on behalf of the Trust Fund,
     pursuant to which the Trustee shall have authority to cause any or all
     securities held in the Trust Fund (excluding both stock of the Company and
     securities held in any portion of the Trust Fund allocated to an
     Investment Manager appointed pursuant to Section 2.1 or to an Investment
     Fund established under Section 2.2 which the Company identifies in writing
     to the Trustee as not being eligible to participate in said program) to be
     lent to such one or more brokers as the Trustee may determine.  The
     Company shall enter into a written agreement with the Trustee setting
     forth the terms and conditions of this appointment, including without
     limitation the compensation to be paid to the Trustee for its services
     with respect to such securities lending program.

2.5  Insurance Valuations and Reports
     --------------------------------

     The Company shall arrange for each insurance company issuing contracts
     held by the Trustee pursuant to Section 2.3, to furnish the Trustee with
     such valuations and reports as are necessary to enable the Trustee to
     fulfill its obligations under ARTICLE IV, and the Trustee shall be fully
     protected in relying upon such valuations and reports.

3.1  Standard of Care
     ----------------

     The Trustee, the members of each Committee, and each Investment Manager
     appointed pursuant to Section 2.1 shall discharge their respective duties
     with respect to the Trust Fund solely in the interest of the employees of
     the Companies which have adopted a Plan and their beneficiaries, and with
     the care, skill, prudence, and diligence under the circumstances then
     prevailing that a prudent man acting in a like capacity and familiar with
     such matters would use in the conduct of an enterprise of like character
     and with like aims.  The duties of the Trustee shall only be those
     specifically undertaken pursuant to this Agreement or by means of a
     separate written agreement.

3.2  Trust Fund Assets
     -----------------

     The Company shall determine whether all or any portion of the assets of a
     Plan shall be deposited in the Trust Fund, and the Trustee shall have no
     responsibility for any such assets until such time as they are in fact
     received by the Trustee for deposit.

3.3  Allocation of Responsibility
     ----------------------------

     Except as otherwise provided in the Act, no "fiduciary" (as such term is
     defined in Section 3(21) of the Act, or any successor statutory provision)
     under this Agreement shall be liable for an act or omission of another
     person in carrying out any fiduciary responsibility where such fiduciary
     responsibility is allocated to such other person by this Agreement or
     pursuant to a procedure established in this Agreement.

3.4  Indemnification
     ---------------

     The Company hereby agrees to indemnify and hold the Trustee harmless from
     and against any loss, costs, damages or expenses, including without
     limitation reasonable attorneys' fees, which the Trustee may incur or pay
     out by reason of any alleged or actual act, or failure to act, on the part
     of the Company, any Company, Committee, Investment Manager, custodian or
     trustee other than this Trustee, or any other person.

3.5  ERISA Controls
     --------------

     Anything in this Agreement to the contrary notwithstanding, no provision
     of this Agreement shall be so construed as to violate the requirements of
     Part 4 of Title I of the Act.

4.1  Records and Accounts
     --------------------

     The Trustees shall keep accurate and detailed accounts of all investments,
     receipts, disbursements and other transactions hereunder, and all
     accounts, books and records relating thereto shall be open to inspections
     and audit at all reasonable times by any persons designated by the
     Company.  Within ninety (90) days following the close of each fiscal year
     of this Trust Fund, which shall be the twelve-month period ending on
     December 31 of each year, and within ninety (90) days after the removal or
     resignation of the Trustee as provided in ARTICLE VIII hereof, the Trustee
     shall file with the Company a written account setting forth all
     investments, receipts, disbursements and other transactions effected by
     the Trustee or reported to it by such Investment Managers as may be
     appointed hereunder during each fiscal year or during the period from the
     close of the last such fiscal year to the date of such removal or
     resignation.  Within sixty (60) days from the date of filing such annual
     or other account, the Trustee, if requested by the Company, shall also
     serve copies of such account upon any persons designated by the Company as
     having administrative responsibility with respect to any Plan.  Upon the
     expiration of 150 days from the date of filing such annual or other
     account, the Trustee shall be forever released and discharged from all
     liability and accountability to anyone with respect to the propriety of
     all acts and transactions shown in such account, except with respect to
     any such acts or transactions as to which the Company, or any person upon
     whom the account has been served pursuant to provisions of this Section
     4.1, shall within such 150 day period file with the Trustee written
     objections.

     The Trustee shall from time to time make such other reports and furnish
     such other information concerning the Trust Fund (including valuations of
     each Investment Fund established pursuant to Section 2.2) as the Company
     may reasonably request or as may be required by a Plan.

4.2  Settlement of Accounts
     ----------------------

     Notwithstanding the foregoing Section 4.1, the Trustee, each Committee,
     and each Company, or any of them, shall have the right to apply at any
     time to a court of competent jurisdiction for the judicial settlement of
     the Trustee's account, and in any case it shall be necessary to join as
     parties thereto only the Trustee, any applicable Committee and any
     applicable Company; and any judgment or decree which may be entered
     therein shall, subject to the provisions of the Act, be conclusive upon
     all persons having or claiming to have any interest in the Trust Fund or
     under a Plan.

5.1  Trustee Expenses
     ----------------

     The expenses incurred by the Trustee in the performance of its duties, or
     otherwise in its capacity as Trustee of the Trust Fund (including, without
     limitation, fees for legal services rendered to the Trustee in any context
     directly or indirectly pertaining to the Trust Fund), such compensation to
     the Trustee (in its capacity as Trustee of the Trust Fund, for the
     maintenance of participant accounts if it has been so directed pursuant to
     Section 2.4) as may be agreed upon in writing from time to time between
     the Trustee and the Company, and all other proper charges and
     disbursements of the Trustee shall be paid from the Trust Fund unless paid
     by the Company in its sole discretion.  The Company may direct the Trustee
     to pay from the Trust Fund the compensation of any Investment Manager
     appointed pursuant to Section 2.1 and the administrative expenses of any
     Plan.  All taxes of any and all kinds whatsoever that may be levied or
     assessed under existing or future laws upon the Trust Fund or the income
     thereof shall be paid from the Trust Fund or the income thereof shall be
     paid from the Trust Fund.  Any amount paid from the Trust Fund (including
     taxes) which is specifically allocable to a particular Plan shall be
     charged to such Plan; any amount paid from the Trust Fund which is
     allocable to all of the Plans shall be charged against the Trust Fund
     without allocation.

     If Investment Funds have been established pursuant to Section 2.2, all
     amounts (including taxes) paid from the Trust Fund which are allocable to
     an Investment Fund shall be charged to such Investment Fund.  All such
     expenses which are not so allocable shall be charged against each of the
     Investment Funds in the same proportion as the value of the total assets
     held in such Investment Fund bears to the value of the total assets in the
     Trust Fund.

     In the case of a loan from a Plan to a member under the Plan, all expenses
     (including taxes) of the Trust Fund, other than those expenses which are
     paid by the Company or a Company, which are allocable to such loan, shall
     be charged against the interest of such member under the Plan.

6.1  Multiple Companies
     ------------------

     Each Company whose Plan shall be designated by resolution of the Board of
     Directors of the Company as eligible to participate in the Trust Fund may
     become a party to this Agreement by delivering to the Trustee (i) a
     certified copy of such resolution, and (ii) a copy, certified by such
     Company's secretary or one of its assistant secretaries under its
     corporate seal, of a resolution adopted by its Board of Directors joining
     in this Agreement and authorizing the Company to exercise the powers
     conferred upon it by this Agreement.  Upon receipt by the Trustee of both
     of such certified copies and a copy of such Company's plan, such Company
     shall be and become a party to this Agreement in all respects as if it had
     executed this Agreement at the foot hereof.  Each Company shall provide
     the Trustee with a copy of a current determination letter from the United
     States Internal Revenue Service to the effect that such Plan is qualified
     under Section 401(a) of the Code and exempt from federal income tax under
     Section 501(a) of the Code.

6.2  Multiple Plans
     --------------

     The Trustee shall maintain a separate account reflecting the equitable
     share in the Trust Fund of each Plan.  Such equitable share shall be used
     solely for the payment of benefits under and expenses and other charges
     properly allocable to each such Plan, and shall not be used for payment of
     benefits under and expenses and other charges properly allocable to any
     other Plan.  The equitable share of each Plan in the Trust Fund shall be
     debited or credited (as the case may be) (a) for the entire amount of
     every contribution received on behalf of such Plan, every benefit payment
     or other expense allocable to such Plan, and every other transaction
     relating solely to such Plan, and (b) for its equitable share of every
     item of collected or accrued income, gain or loss, and general expenses
     and other transactions allocable to the Trust Fund as a whole.  The
     Trustee shall determine the value of the assets of the Trust Fund as of
     such dates as the Trustee may deem appropriate or as a Committee with the
     assent of the Trustee may direct.  Assets shall be valued at their market
     values at the close of business on the date of valuation, or, in the
     absence of readily ascertainable market values, at such values as the
     Trustee shall determine, in accordance with methods consistently followed
     and uniformly applied.  In determining market values of assets, the
     Trustee may rely on values recommended by the Investment Manager or
     Investment Trustee responsible for the investment of such assets.

6.3  Trustee Reliance
     ----------------

     The Company shall certify to the Trustee the names and specimen signatures
     of the members of each Committee appointed to administer a Plan.  The
     Company shall promptly give notice to the Trustee of changes in the
     membership of each such Committee, and, until such notices are received by
     the Trustee, the Trustee shall be fully protected in assuming that the
     membership of such Committee is unchanged and in acting accordingly.  Each
     Committee may certify to the Trustee the names of

                                       14
<PAGE>
 
     persons authorized to act for it in relation to the Trustee and the
     Trustee may act upon any certificate, notice or direction purporting to
     have been signed on behalf of a Committee which the Trustee believes to be
     genuine and to have been executed by the Committee or by any person whose
     authority to act for the Committee has been certified to the Trustee by
     the Committee.  The Trustee may rely upon any certificate, notice or
     direction of the Company which the Trustee believes to be genuine and to
     have been signed by a duly authorized officer of the Company. 
     Communications from the Company and from each Committee to the Trustee
     shall be sent to the Trustee's office as stated above or to such other
     address as the Trustee shall specify, and such communications shall be
     binding upon the Trust Fund and the Trustee, when received by the Trustee.

6.4  Directions by Company or Committee
     ----------------------------------

     All orders, requests, instructions and objections of any of the persons
     authorized to act on behalf of a Company or any Committee in accordance
     with the provisions of Section 6.3, or designated to direct the Trustee
     under Section 1.2 to make payment for the purpose of distributing
     benefits, shall be in writing (provided that the Trustee may, in its
     discretion, accept oral orders, requests, instructions and objections
     subject to confirmation in writing), and the Trustee shall be fully
     protected in acting in accordance therewith.

6.5  Directions by Investment Manager
     --------------------------------

     All directions to the Trustee of any Investment Manager appointed pursuant
     to Section 2.1 shall be in writing (provided that the Trustee may, in its
     discretion, accept oral direction subject to confirmation in writing) and
     shall be signed by an officer (or partner) of the Investment Manager or by
     a person specifically designated to act for the Investment Manager by an
     officer (or partner) thereof.

6.6  Certain Securities Transactions
     -------------------------------

     Notwithstanding anything herein to the contrary, the Trustee shall be
     fully protected in acting in accordance with directions with respect to
     securities transactions (including, without limitation, the affirmation
     and/or confirmation of such transactions) received by it through a system
     or arrangement for the coordination of securities transaction settlements
     operated by Depository Trust Company or by any other central securities
     depository, securities clearing organization or book entry system which
     serves to link investment managers, securities brokers and custodian
     banks, pursuant to an agreement entered into by the Trustee, and an
     Investment Manager appointed pursuant to Section 2.1 or the Company, as
     the case may be, to the same extent as if the directions were in writing.

7.1  Amendment and Termination
     -------------------------

     The Company may, at any time and from time to time, by instrument in
     writing executed pursuant to authorization of this Board of Directors, (a)
     amend in whole or in part any or all of the provisions of this Agreement,
     or (b) terminate this Agreement and the trust created hereby; provided,
     however, that no amendment which affects the rights, duties or
     responsibilities of the Trustee may be made without the Trustee's consent
     and provided further that no such amendment shall divert any part of the
     Trust Fund to purposes other than for the exclusive benefit of the
     employees of an Company or their beneficiaries except to the extent
     permitted by this Agreement or any Plan.  Any such amendment shall become
     effective upon receipt by the Trustee of the instrument of amendment or,
     subject to the consent of the Trustee, as of the date specified therein,
     and endorsement thereon by the Trustee of its consent thereto, if such
     consent is required.  Any such termination shall become effective upon the
     receipt by the Trustee of the instrument of termination; thereafter the
     Trustee, upon the direction of the Company, shall liquidate the Trust Fund
     to the extent required for distribution and, after the final account of
     the Trustee has been approved and settled, shall distribute the balance of
     the Trust Fund remaining in its hands as directed by the Company or
     appropriate Committee, or in the absence of such direction, as may be
     directed by a judgment or decree of a court of competent jurisdiction. 
     Upon termination of the Trust Fund as provided herein, the Trustee shall
     not be required to make any payments hereunder in excess of the net
     realizable value of the assets of the Trust Fund at the time of such
     payment.  The Trustee shall not be required to make any payments in cash
     unless there shall be in the Trust Fund at the time an amount of cash
     sufficient for the purpose.  In case of a deficiency in cash, the Trustee
     shall take such action as to the disposition of securities or other
     property forming a part of the Trust as will provide the amount of cash
     necessary for such payments. Following any such termination, the powers of
     the Trustee hereunder shall continue as long as any of the Trust Fund
     remains in its hands, but only as to those assets which during such time
     remain in the Trust Fund.

8.1  Removal and Resignation
     -----------------------

     The Trustee may be removed by the company at any time upon thirty (30)
     days' notice in writing to the Trustee.  The Trustee may resign at any
     time upon thirty (30) days' notice in writing to the Company.  The
     parties, however, may by written instrument waive such notice.  Upon such
     removal or resignation of the Trustee, the Company shall appoint a
     successor trustee who shall have the same powers and duties as those
     conferred upon the Trustee hereunder subject to such changes as the
     Company may then determine.  If a successor trustee is not appointed
     within thirty (30) days after the Trustee gives notice of its resignation,
     the Trustee may apply to any court of competent jurisdiction for
     appointment of a successor.  Upon acceptance of such appointment by the
     successor trustee, the Trustee shall assign, transfer and pay over to such
     successor trustee the assets then constituting the Trust Fund.  The
     Trustee is authorized, however, to reserve such sum of money as may be
     reasonable for payment of its compensation and expenses (including legal
     expenses) in connection with the settlement of its account or otherwise,
     and any balance of such reserve remaining after the payment of such
     compensation and expenses shall be promptly paid over to the successor
     trustee.

9.1  Governing Law
     -------------

     To the extent permitted by applicable law this Agreement shall be
     administered, construed and enforced according to the laws of the state of
     Washington.

9.2  Successors and Assigns
     ----------------------

     This Agreement shall be binding upon, and the powers granted to the
     Company and the Trustee, respectively, shall be exercisable by, the
     respective successors and assigns of the Company and the Trustee.  Any
     corporation which shall, by merger, consolidation, purchase or otherwise,
     succeed to substantially all the trust business of the Trustee shall, upon
     such succession and without any appointment or other action by the
     Company, be and become successor trustee hereunder, upon notification to
     the Company.

9.3  Loss of Qualification
     ---------------------

     The Company shall immediately notify the Trustee if any Plan ceases to be
     qualified under Section 401(a) of the Code.  That part of the Trust Fund
     which is attributable to any such Plan shall be immediately segregated and
     withdrawn from the Trust Fund.  The Company may at any time direct the
     Trustee to segregate and withdraw the part of the Trust Fund which is
     attributable to any Plan or to any specified group or groups of employees
     or beneficiaries as certified to the Trustee by the Company.  Whenever
     segregation is to be effected pursuant to this Section, the Trustee shall
     withdraw from the Trust Fund such assets as the Company shall direct. 
     Such assets shall be equal in value to the part of the Trust Fund to be
     segregated.  Such withdrawal from the Trust Fund shall be in cash or in
     any property held in the Trust Fund, or in a combination of both, as
     directed by the Company, and the Trustee's valuation of the assets of the
     Trust Fund for such purpose shall be conclusive and binding on all
     persons.  The Trustee shall thereafter hold the assets so withdrawn as a
     separate trust fund in accordance with the provisions either of this
     Agreement or of a separate trust agreement.  Such segregation shall not
     preclude later readmission to the Trust Fund.

9.4  Segregation of Assets
     ---------------------

     The Company may, if it so determines, at any time and from time to time,
     designate any group or groups of the eligible employees or other
     beneficiaries covered by a Plan as a separate class and may direct the
     Trustee to segregate in a separate fund, to be held for the benefit of
     such class, the part of the Trust Fund allocable to such class as
     determined by the Company.  The Company shall cause the Trustee to effect
     such segregation by delivering to the Trustee a certified copy of the
     Company's determination, together with a certified copy of a resolution or
     resolutions of the Board of Directors of the Company directing such
     segregation.  The Trustee may rely conclusively and without investigation
     upon any such certified copy of such determination and such resolution and
     shall segregate such assets as the Company

                                       18
<PAGE>
 
     may direct.  The Trustee's valuation of such assets for that purpose shall
     be conclusive.  The Trustee shall hold all of the assets so segregated
     under this provision, together with such payments as shall thereafter be
     made to the Trust Fund in behalf of such class, and the income therefrom,
     as a subpart of the Trust Fund and subject to the terms of this Agreement,
     or shall dispose of the same as directed by the Company.  In the event
     that the Trust or any subpart thereof created by this Agreement shall be
     terminated as to such class, the Company shall direct the disposition of
     the assets held by the Trustee for such class through transfer to a
     successor trust, the purchase of annuities, or other means, as the Company
     shall determine, and thereafter such employees and other beneficiaries
     shall not have any rights in the Trust Fund, or against the Trustee.

9.5  Exclusive Benefit
     -----------------

     Except as specifically permitted by this Agreement or any Plan, at no time
     shall any part of the Trust Fund which is attributable to such Plan ever
     revert to or be used or enjoyed by the Company or any Company or be used
     for, or diverted to, any purposes other than for the exclusive purpose of
     providing benefits to eligible employees and their beneficiaries and the
     payment of the reasonable expenses of the Plan.  Notwithstanding any
     provision hereof to the contrary, contributions by a Company may be
     returned to the Company under the following circumstances, but only if
     requested by the Company by written certification to the Trustee that the
     return of property to the Company is in compliance with the provisions of
     this Agreement and the applicable Plan:

     (a) if a contribution is made by a Company by reason of a mistake of fact,
         provided that such repayment to the Company is made within one (1) year
         after the payment by the Company of such contribution to the Trust, or

     (b) if a contribution, or any portion thereof, was made upon the condition
         that it be fully deductible for federal tax purposes but in fact it is
         not deductible to the Company under Section 404 of the Code (or any
         successor provision thereto), provided that the contribution so made,
         to the extent so disallowed, is repaid to the Company within one (1)
         year after the date of disallowance of the deduction.

     Any contribution returned to a Company pursuant to this Section 9.5 shall
     be adjusted to reflect its share of the Trust Fund's loss, if any, but not
     of the Trust Fund's gain.  The Trustee shall be entitled to rely
     completely on such written certification and shall be under no obligation
     to investigate or otherwise determine its propriety.  The Trustee shall
     not incur any liability or other loss or damage on account of its reliance
     on such certification.

9.6  No Certificates of Ownership
     ----------------------------

     No document shall be issued evidencing any interest in the Trust Fund and
     no Plan shall have power to assign all or any part of the Trust Fund
     attributable to it.

                                       19
<PAGE>
 
9.7  Assignability
     -------------

     To the maximum extent permitted by law, beneficial interests in the Trust
     Fund of members or former members under a Plan or their beneficiaries
     shall not be assignable or subject to alienation, sale, transfer, pledge,
     encumbrance, mortgage, attachment, execution, levy or receivership, nor
     shall they pass to any trustee in bankruptcy or be reached or applied by
     any legal process for the payment of any obligations of any such person;
     provided, however, that nothing herein shall prevent a member from
     assigning his interest in the Trust Fund as security for the repayment of
     any loan made to him from the Trust Fund pursuant to a Plan or prevent the
     payment of amounts pursuant to a qualified domestic relations order.  Any
     attempt at such a prohibited assignment, alienation, sale, transfer,
     pledge, encumbrance, mortgage, attachment, execution or levy shall be void
     and unenforceable.

                                  DEFINITIONS


The following terms when used herein shall have the following meaning, unless a
different meaning is plainly required by the context.  Capitalized terms are
used throughout the Plan text for terms defined by this and other sections.

     of two payments or series of payments shall be of equal value when computed
     at an 8% rate of interest and on the basis of the 1984 Unisex Pension

     For purposes of the limitation on benefits in Sections 8.2 and 8.3, the
     determination of whether an entity is an Affiliated Company will be made by
     modifying Sections 414(b) and (c) of the Code as specified in Section
     415(h) of the Code.

                    (2)  the maximum amount of the Participant's account balance
                         in the Westmark International Incorporated
                         Discretionary Contribution Plan (excluding any rollover
                         or transfer amount), as of December 31, 1988, which,
                         when accumulated with 8% interest compounded annually
                         to the later of January 1, 1989 and the Normal
                         Retirement Date and then divided by 100, does not
                         exceed the Participant's monthly benefit under this
                         Plan as of December 31, 1988.

     Notwithstanding the foregoing, a Participant's Accrued Benefit shall not be
     less than his or her Accrued Benefit on the date immediately preceding the

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

     A Participant's monthly Deferred Retirement Benefit shall equal his or her
     vested Accrued Benefit as of the date of Termination, and then adjusted for
     form of payment.  Service and Earnings beyond the Normal Retirement Date
     shall be taken into consideration.  In no event shall the benefit provided
     under this paragraph be less than the retirement benefit to which the
     Participant would have been entitled if he or she had actually retired on
     the Normal Retirement Date, Actuarially increased to reflect the deferred
     commencement of payments.

     shall be based on his or her total Credited Service and Earnings at the
     time of subsequent retirement, and shall be reduced by the Actuarially
     Equivalent value of benefits previously received by the Participant.  In no
     event shall the benefit upon subsequent retirement, after any reduction for
     previously received benefits, be less than the initial retirement benefit.

4.7  Benefits For Terminated Participants
     ------------------------------------

     Benefits under the Plan shall be determined and paid in accordance with the
     provisions of the Plan as in effect on the most recent date of a

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

     Notwithstanding anything herein to the contrary, if an individual was a

                                FORMS OF PAYMENT


5.1  Forms of Payment
     ----------------

     The following forms of benefit payments are available under this Plan:

     (a)  Whole Life Annuity:
          ------------------ 

          A Whole Life Annuity shall be payable monthly from the Retirement Date
          to the first of the month preceding death.  The amount of the monthly
          benefit shall equal the monthly Normal, Early or Deferred Retirement
          Benefit, whichever applies.

     (b)  Joint and Survivor Annuity:
          -------------------------- 

          A reduced Joint and Survivor Annuity shall be payable monthly to a
          retired Participant from the Retirement Date or Vested Termination
          Date to the first of the month preceding death.  Following the
          Participant's death, a retirement benefit equal to 50% or 100% of the
          reduced amount payable to the retired Participant shall be payable for
          life to the joint annuitant, if living at the time of the
          Participant's death.  A Participant may elect, before benefits
          commence, which percentage shall be payable to the joint annuitant.

          If the joint annuitant dies after the Participant's retirement income
          begins, the Participant's payments will be in the same reduced amount
          as is otherwise payable under the Joint and Survivor Annuity.  If the
          joint annuitant dies prior to the date as of which the Participant's
          retirement income begins, any election of a form of benefit under this
          Section 5.1(b) shall be automatically canceled.  If the Participant
          dies prior to the date as of which his or her retirement income is to
          begin, the joint annuitant shall not be entitled to receive any
          payments under this Section 5.1(b).  However, a spouse joint annuitant
          may be entitled to a benefit under Section 6.1.

          The Joint and Survivor Annuity shall be Actuarially Equivalent to the
          Participant's retirement benefit payable in the form of a Whole Life
          Annuity.

     (c)  Lump Sum:
          -------- 

          A Lump Sum distribution shall be a single sum payment.  The Lump Sum
          distribution shall be Actuarially Equivalent to the Participant's
          retirement benefit payable in the form of a Whole Life Annuity, and
          shall represent the Participant's entire interest in the Plan.  Lump
          sum distributions may not exceed $10,000.

                                       17

5.2  Automatic Form of Benefit
     -------------------------

     Unless a Participant elects otherwise, benefits shall be paid as provided
     below:

     (a)  Married Participants
          --------------------

          Any Participant who is married on his or her Annuity Starting Date or
          Vested Termination Date shall automatically be deemed to have elected
          the 50% Joint and Survivor Annuity option, effective as of such date,
          with his or her spouse on the Annuity Starting Date as the joint
          annuitant (the "Statutory 50% Joint and Survivor Annuity Option").

          A married Participant may reject the Statutory 50% Joint and Survivor
          Annuity Option, or elect a nonspouse joint annuitant pursuant to
          Section 5.3, by filing a written notice with the Committee within
          ninety days prior to his or her Annuity Starting Date.  Such notice
          must specify the form of payment elected, name the non-spouse joint
          annuitant if any, acknowledge the effect of the election, and must be
          signed by the Participant's spouse.  The spouse's signature must be
          notarized or witnessed by a Plan representative.

          A married Participant may file a rejection or joint annuitant election
          notice or revoke any such notice at any time during the ninety-day
          election period immediately preceding the Annuity Starting Date.

     (b)  Other Participants
          ------------------

          An unmarried Participant shall receive his or her retirement benefits
          in the form of a Whole Life Annuity.
 
          An unmarried Participant may reject the Whole Life Annuity option and
          elect either a Joint and Survivor Annuity or a Lump Sum option by
          filing a written notice with the Committee within ninety days prior to
          his or her Annuity Starting Date.  An unmarried Participant may file
          or revoke such a notice at any time during the ninety-day period
          immediately preceding the Annuity Starting Date.

5.3  Limitation on Forms of Payment
     ------------------------------

     A Participant may elect a joint annuitant other than his or her spouse.  A
     Participant must elect a form of payment under which payments will be
     completed within the Participant's and Beneficiary's life times or within
     their life expectancies.  If a Participant elects a joint annuitant other
     than his or her spouse, the percentage selected by the Participant to be
     payable to the joint annuitant cannot exceed the percentage in the table
     set forth in Q&A A-6 of Section 1.401(a)(9)-2 of the proposed Income Tax
     Regulations, determined according to the age difference between the
     Participant and the joint annuitant.

5.4  Explanation of Forms of Payment
     -------------------------------

     The Committee shall furnish each Participant with a written explanation of
     the terms and conditions of the forms of payment within a reasonable period
     (at least thirty but not more than ninety days) prior to the Participant's
     Annuity Starting Date.

5.5  Directed Rollovers
     ------------------

     (a)  General Rule
          ------------

          A Participant or spouse Beneficiary who is entitled to a lump sum
          benefit pursuant to Section 10.8(c), or who elects a Lump Sum
          distribution pursuant to Section 5.1(c) may direct the Committee to
          pay part or all of the benefit to a trustee or custodian of another
          employer's qualified plan which accepts such directed rollovers or an
          individual retirement account (IRA), subject to the following
          provisions:

          (i)  A Participant or Beneficiary may only direct such a rollover if
               the expected benefit payment during the Plan Year is $200 or
               more.

          (ii) A Participant or Beneficiary may not request a directed rollover
               of an amount distributed due to the minimum required distribution
               provision under Section 10.6(b).

          (iii)The rollover of a distribution may only be directed to one
               qualified plan or IRA.

          (iv) A Participant or Beneficiary may direct the rollover of a portion
               of the distribution and elect to receive the remaining portion of
               a distribution only if the rollover amount is at least $200.

          (v)  A surviving spouse Beneficiary or a former spouse who is an
               alternate payee pursuant to Section 10.9 may direct a rollover
               under the same terms and conditions as a Participant, except that
               such spouse or former spouse may only direct a rollover to an
               IRA.

          (vi) A non-spouse Beneficiary may not direct a rollover pursuant to
               this section.

          (vii)A Participant or Beneficiary provides the information or
               documentation reasonably requested by the Committee.

     (b)  Notice to Participants
          ----------------------

          The Committee shall furnish each Participant and Beneficiary eligible
          for a directed rollover under this Section 5.5 with a written
          explanation of the directed rollover opportunity and related
          withholding consequences of not choosing a directed rollover within a
          reasonable period (at least thirty (30) but not more than

                                       19

          Starting Date; provided, however, that a Participant or Beneficiary
          may waive in writing the thirty (30) day period with respect to a
          distribution of small benefits equal to $3,500 or less.

                         DEATH AND DISABILITY BENEFITS


6.1  Spouse's Death Benefit
     ----------------------

     In the event a vested Participant dies before commencing to receive
     retirement benefits or Vested Termination Benefits under the Plan, his or
     her spouse shall receive a pre-retirement death benefit provided they were
     married throughout the one year period ending on the date of death.  The
     amount of the spouse's benefit and time of commencement is described below.
     The spouse of a nonvested Participant, or a Participant who has started to
     receive benefits, or a spouse who was married to the Participant less than
     one year, is not entitled to this death benefit.

     (a)  Death Following Early Retirement Date
          -------------------------------------

          If the Participant dies after he or she becomes eligible to elect an
          Early Retirement Date, the spouse's benefit shall be paid monthly from
          the first of the month coinciding with or following the Participant's
          death through the first of the month preceding the spouse's death.
          The benefit shall equal the amount payable to the surviving spouse
          under a 50% Joint and Survivor Annuity form of payment if the
          Participant had commenced receiving retirement benefit payments as of
          the date spouse benefits commence, based upon the Participant's vested
          Accrued Benefit at the date of death.

     (b)  Death Prior to Early Retirement Date
          ------------------------------------

          If the Participant dies prior to becoming eligible to elect an Early
          Retirement Date, the spouse's benefit shall be paid monthly from the
          Participant's earliest Retirement Date (determined as if he or she had
          survived) through the first of the month preceding the spouse's death.
          The benefit shall equal the amount payable to the surviving spouse
          under a 50% Joint and Survivor Annuity form of payment if the
          Participant had Terminated on the date of death, survived to the date
          spouse benefits commence and commenced receiving retirement benefit
          payments on such date.

     Notwithstanding the foregoing, in the event a Participant dies prior to
     Normal Retirement Date, a spouse entitled to benefits under (a) or (b)
     above, may elect prior to the date benefits commence thereunder, to
     postpone commencement of benefits to the first day of any month on or
     before the Participant's Normal Retirement Date determined as if he or she
     had survived.  The benefit payable at such delayed commencement date shall
     be the Actuarial Equivalent of the spouse's death benefit payable at the
     terms specified under (a) or (b) above.

6.2  Disability Benefits
     -------------------

     A Participant who becomes Disabled shall be deemed to be in Service for
     purposes of vesting and benefit accrual until the earlier of (i) the date
     of recovery from Disability, (ii) an Early Retirement Date elected by the
     Participant, or (iii) Normal Retirement Date.  For purposes of determining
     a Participant's Accrued Benefit, average Earnings for the twelve months
     preceding the date of Termination are deemed to be in effect during
     Disability.

                                    VESTING

7.1  Vesting
     -------

     Each Participant shall have a vested, nonforfeitable right to his or her
     Accrued Benefit multiplied by the appropriate vesting percentage in
     accordance with the following table:

<TABLE>
<CAPTION>

     Periods of Service       Percent Vested
     ------------------       --------------
     <S>                      <C>
     Less than 5 years              0%
     5 years or more                100%

</TABLE>

     In addition, each Participant shall have a 100% nonforfeitable right to his
     or her Accrued Benefit on the first day of the month preceding his or her
     Normal Retirement Date, provided he or she is an Employee on such date.  An
     Employee who Terminates with 0% vested shall be deemed "nonvested."

7.2  Termination Prior to Vesting
     ----------------------------

     (a)  Forfeiture of Service
          ---------------------

          In the event a nonvested Participant incurs a Period of Severance, and
          the number of years in such Period of Severance equals or exceeds five
          consecutive years, his or her Period of Service and Credited Service
          preceding the Severance from Service Date shall be disregarded, and
          any Accrued Benefit earned prior to the Severance from Service Date
          shall be forfeited.  If a vested Participant incurs a Period of
          Severance, all Periods of Service and Credited Service before and
          after the Period of Severance shall be aggregated.

     (b)  Deemed Cash-Out of Accrued Benefit
          ----------------------------------

          If an Employee Terminates at a time when the present value of the
          Employee's vested Accrued Benefit is zero, the Employee shall be
          deemed to have received a distribution of such vested Accrued Benefit,
          and shall no longer be a Participant.  If the individual resumes
          employment with the Employer before incurring a five-consecutive-year
          Period of Severance, the Accrued Benefit will be restored to the
          amount of such Accrued Benefit on the date of the deemed distribution.

7.3  Forfeitures
     -----------

     Any forfeitures arising under this Plan shall be used only to offset future
     Employer contributions and shall not affect any Participant's Accrued
     Benefit.

          shall not exceed the lesser of:

             (i)  $90,000 (adjusted in accordance with this Section 8.2) or, if
                  greater, the Participant's current Accrued Benefit on December
                  31, 1982, or

             (ii) the Participant's average annual Compensation from the
                  Employer for the consecutive calendar years (not in excess of
                  three such years) during which he was an active Participant in
                  the Plan and for which such average is highest.

     (b)  Cost-of-Living Adjustment
          -------------------------

          The $90,000 limit prescribed above shall be automatically adjusted for
          cost-of-living increases, to the maximum permissible dollar limitation
          determined by the Commissioner of Internal Revenue.  The dollar amount
          applicable in computing the benefit payable to any Participant shall
          be the dollar amount in effect for the calendar year in which the
          benefit commences.  For 1992, the limit is $112,221.

     (c)  Adjustment for Early or Late Retirement
          ---------------------------------------

          For purposes of 8.2 and 8.3, if the Participant's benefit commences
          before Social Security Retirement Age, the limit prescribed in Section
          8.2(a)(1) shall be Actuarially reduced to reflect such early
          commencement.  If the Participant's benefit commences after Social
          Security Retirement Age, the limit prescribed in Section 8.2(a)(1)
          shall be Actuarially increased for purposes of Section 8.2 and Section
          8.3 to reflect such late commencement.

     (d)  Annual Benefit
          --------------

          Notwithstanding the foregoing, if the benefit to be paid to a
          Participant under the Plan is not in the form of an Annual Benefit as
          described below, the benefit considered to be payable to a Participant
          under the Plan for purposes of Sections 8.2 and 8.3 shall be
          Actuarially adjusted to the extent required under Section 415(b)(2) of
          the Code.  For purposes of the foregoing, Annual Benefit means the
          benefit payable annually in the form of a straight life annuity
          without ancillary benefits or in the Statutory 50% Joint and Survivor
          Annuity Option.

     (e)  Interest Rate
          -------------

          Any Actuarial adjustments under this Section 8.2 shall be based on the
          Actuarial factors applicable for comparable purposes under the Plan on
          the applicable date, except that

          (i)  the interest rate assumption for purposes of adjusting the
               $90,000 limitation for benefits commencing before Social Security
                                                          ------                
               Retirement Age shall be the greater of 5% or the Plan rate; and
                                           -------                            

          (ii) the interest rate assumption for purposes of adjusting the
               $90,000 limitation for benefits commencing after Social Security
                                                          -----                
               Retirement Age shall be the lesser of 5% or the Plan rate.
                                           ------                        

     (f)  Special Provisions Regarding Participants With Fewer Than Ten Years of
          ----------------------------------------------------------------------
          Participation or Service
          ------------------------

          In the case of any Participant who participated in the Plan for fewer
          than ten years, the maximum dollar benefit otherwise applicable under
          Section 8.2(a)(i) shall be multiplied by a fraction whose numerator is
          the Participant's years of participation in the Plan (including
          fractions thereof, but not less than one) and whose denominator is
          ten.

          In the case of any Participant who was employed by the Employer for
          fewer than ten years, the maximum benefit otherwise applicable under
          Sections 8.2(a)(ii) and 8.3 shall be multiplied by a fraction whose
          numerator is the Participant's years of employment with the Employer
          (including fractions thereof, but not less than one) and whose
          denominator is ten.

     (g)  Transition Rule
          ---------------

          The limitations of this Section 8.2 shall not reduce a Participant's
          annual benefit to less than his or her Accrued Benefit as of December
          31, 1986, disregarding any change in the terms of the Plan and any
          cost-of-living adjustments after May 5, 1986.

<PAGE>
 
     (h)  Aggregation With Other Defined Benefit Plans
          --------------------------------------------

          If a Participant also participates in any other defined benefit
          pension plan maintained by the Employer, the provisions of Section 8.2
          and 8.3 shall be applied on an aggregate basis to the benefits payable
          under this Plan and each such other plan.  Any reduction in the
          aggregate benefits payable under this Plan and any such other plan due
          to the application of this Section shall be made on a pro-rata basis.

8.3  Additional Limitation Relating to Defined Contribution Plans
     ------------------------------------------------------------

     (a)  Primary Rule
          ------------

          For Participants who participate in this Plan and a defined
          contribution plan maintained by the Employer, the sum of (1) and (2)
          below for any calendar year may not exceed 1.0.

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

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

               (ii) The lesser of:  (a) 1.25 multiplied by the limitation
                    determined under Section 8.2(a)(1) in effect for such year,
                    or (b) 1.4 multiplied by the limitation determined under
                    Section 8.2(a)(2) (generally 100% of the Participant's
                    average annual Compensation).

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

               (i)  The sum of the "annual additions" to the Participant's
                    accounts for the current year, as of the close of the year,
                    and for all prior years.

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

     (b)  Remedy
          ------

          If such sum exceeds 1.0, the benefit under this defined benefit Plan
          shall be reduced to the extent necessary to satisfy the limitations of
          this section.

                              TOP HEAVY PROVISIONS

9.1  Scope
     -----

     Notwithstanding any Plan provision to the contrary, for any Plan Year in
     which the Plan is Top Heavy within the meaning of Section 416(g) of the
     Code, the provisions of this Section 9 shall govern to the extent they
     conflict with or specify additional requirements to the Plan provisions
     governing Plan Years which are not Top Heavy.

9.2  Top Heavy Status
     ----------------

     (a)  Top Heavy
          ---------

          This Plan shall be "Top Heavy" if, as of the Determination Date, (1)
          the sum of the Aggregate Accounts of Key Employees, or (2) the Present
          Value of Accrued Benefits of Key Employees under this Plan and any
          plan of an Aggregation Group, exceeds 60% of the Aggregate Accounts or
          the Present Value of Accrued Benefits of all Participants under this
          Plan and any plan of an Aggregation Group.

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

     (b)  Super Top Heavy
          ---------------

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

     (c)  Determination Date
          ------------------

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

                                       28
<PAGE>
 
     (d)  Valuation Date
          --------------

          "Valuation Date" means, for purposes of determining Top Heaviness, the
          Determination Date.

     (e)  Aggregate Account
          -----------------

          "Aggregate Account" means, with respect to a Participant, his or her
          adjusted account balance in a defined contribution plan, as determined
          under the top heavy provisions of such plan.

     (f)  Present Value of Accrued Benefits
          ---------------------------------

          "Present Value of Accrued Benefits" means the sum of:

          (i)  the Actuarial Equivalent present value of the accrued normal
               retirement benefit under the Plan as of the Valuation Date, and

          (ii) distributions prior to the Valuation Date, made during the
               Plan Year that contains the Determination Date and the four
               preceding Plan Years.  Unrelated rollovers or transfers from 
               this plan shall be considered distributions.  A related 
               rollover or transfer from this Plan shall not be considered
               a distribution.

          An unrelated rollover or transfer is one which is both initiated by
          the Employee and made between plans of different employers.  A related
          rollover or transfer is one which is either not initiated by the
          Employee or made between plans of the same employer.

     (g)  Key Employee
          ------------

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

          (i)  an officer of the Employer whose annual aggregate Compensation
               from the Affiliated Companies exceeds 50% of the dollar
               limitation under Section 415(c)(1)(A) of the Code ($56,111 for
               the Plan Year ending in 1992), provided that no more than 50
               Employees shall be considered officers, or if less, the greater
               of 10% of the Employees or 3,

          (ii) one of the ten Employees owning the largest interest in the
               Employer who owns more than a 0.5% interest of the Employer, and
               whose annual aggregate Compensation from the Affiliated Companies
               exceeds the dollar limitation under Section 415(c)(1)(A) of the
               Code ($30,000 for the Plan Year ending in 1992),

                                       29
<PAGE>
 
           (iii)an Employee who owns more than 5% of the Employer, or

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

     (h)  Aggregation Group
          -----------------

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

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

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

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

9.3  Minimum Benefit
     ---------------

     (a)  General Rule
          ------------

          For any Top Heavy Plan Year, a non-Key Employee who completes a Year
          of Service shall have an Accrued Benefit at least equal to the minimum
          benefit described herein.  The minimum Accrued Benefit at any point in
          time equals the lesser of:

          (i)  two percent multiplied by Top Heavy Years of Service, or

          (ii) twenty percent,

                                       30
<PAGE>
 
          multiplied by such Participant's "average Compensation."  "Average
          Compensation" means a Participant's average Compensation for the five
          consecutive years when such Participant had the highest aggregate
          Compensation from the Employer.  However, Compensation received for
          non-Top Heavy Plan Years shall be disregarded.  The benefit described
          herein is expressed as an annual benefit in the form of a single life
          annuity (with no ancillary benefits), commencing at normal retirement
          age.

          A non-Key Employee shall not be denied this minimum benefit because he
          or she was not employed on a specified date, failed to make any
          mandatory Employee contribution, or failed to earn a specified amount
          of Compensation.

     (b)  Special Two Plan Rule
          ---------------------

          Where this Plan and a defined contribution plan belong to an
          Aggregation Group that is determined Top Heavy, the Employer shall not
          be required to provide the minimum benefit under (a) above on behalf
          of any non-Key Participant who also participates in the defined
          contribution plan if the Employer contributions and forfeitures under
          the defined contribution plan equal 5% of each non-Key Participant's
          Compensation.

9.4  Benefit Limitation
     ------------------

     For any Top Heavy Plan Year in which the Employer does not make the extra
     minimum allocation provided below, 1.0 shall replace the 1.25 factor found
     in the denominators of the defined benefit and defined contribution plan
     fractions for purposes of calculating the combined limitation on benefits
     under a defined benefit and defined contribution plan pursuant to Section
     415(e) of the Code (see Section 8.3).

     If this Plan is Top Heavy, but is not Super Top Heavy, the above referenced
     fractions shall remain unchanged provided the Employer provides an extra
     minimum Accrued Benefit for each non-Key Employee.  The extra benefit (in
     addition to the minimum benefit set forth in Section 9.3) shall equal the
     lesser of:

     (i)  one percent multiplied by Top Heavy years of Service, or

     (ii) ten percent,

     multiplied by such Participant's "average Compensation", as defined in
     Section 9.3.

9.5  Vesting
     -------

     (a)  Top Heavy Schedule
          ------------------

          For any Top Heavy Plan Year, each Participant who completes an Hour of
          Service in such Year shall become vested and have a nonforfeitable
          right to retirement benefits he or she has earned under the Plan in
          accordance with the following table:

                                       31
<PAGE>
 
<TABLE>
<CAPTION>

          Periods of Service    Vesting Percentage

          <S>                   <C>
          Less than 2 Years           0%
               2 Years               20%
               3 Years               40%
               4 Years               60%
               5 Years              100%

</TABLE>
          Provided, however, that a Participant's vesting percentage shall not
          be less than the percentage determined under the table in Section 7.1.

     (b)  Return to Non-Top Heavy Status
          ------------------------------

          If the Plan becomes Top Heavy and ceases to be Top Heavy in any
          subsequent Plan Year, the vesting schedule shall automatically revert
          to the vesting schedule in effect before the Plan became Top Heavy.
          Such reversion shall be treated as a Plan amendment pursuant to the
          terms of the Plan, and shall not cause a reduction of any
          Participant's nonforfeitable interest in the Plan on the date of such
          amendment.

          A Participant with three or more Years of Service with the Employer as
          of the end of the election period, may elect to remain covered by the
          Top Heavy vesting schedule.  The Participant's election period shall
          commence on the adoption date of the amendment and shall end 60 days
          after the latest of:

          (i)  the adoption date of the amendment,

          (ii) the effective date of the amendment, or

          (iii)the date the Participant receives written notice of the
               amendment from the Committee.

                           ADMINISTRATION OF THE PLAN


10.1 Plan Administrator
     ------------------

     The Plan Administrator shall be the Employer.  The Compensation Committee
     of the Board of Directors of the Employer shall appoint a Committee
     composed of one or more persons which shall carry out the general
     administration of the Plan.  Every member of the Committee shall be deemed
     a fiduciary.  No Committee member who is an Employee shall receive
     compensation with respect to his or her service on the Committee.  Any
     member of the  Committee may resign by delivering written resignation to

          application form is submitted to the Committee.

     (b)  Notice of Denial
          ----------------

          Any time a claim for benefits is wholly or partially denied, the
          Participant or Beneficiary (hereinafter "Claimant") shall be given
          written notice of such action within 90 days after the claim is filed,
          unless special circumstances require an extension of time for
          processing. (If there is an extension, the Claimant shall be notified
          of the extension and the reason for the extension within the initial
          90 day period. The extension shall not exceed 180 days after the
          claim is filed.) Such notice will indicate the reason for denial, the
          pertinent provisions of the Plan on which the denial is based, an
          explanation of the claims appeal procedure set forth herein, and a
          description of any additional material or information necessary to

          information is necessary.

     (c)  Right to Request Review
          -----------------------

          Any person who has had a claim for benefits denied by the Committee,
          who disputes the amount of benefit payment determined by the
          Committee, or who is otherwise adversely affected by action of the
          Committee, shall have the right to request review by the Committee.
          Such request must be in writing, and must be made within 60 days after
          such person is advised of the Committee's action. If written request
          for review is not made within such 60-day period, the Claimant shall
          forfeit his or her right to review.  The Claimant or a duly authorized
          representative of the Claimant may review all pertinent documents and
          submit issues and comments in writing.

          modifying or setting aside its former action within 60 days after
          receipt of the written request for review, or 120 days if special
          circumstances, such as a hearing, require an extension.  The Claimant
          shall be notified in writing of any such extension within 60 days
          following the request for review.  A copy of the decision shall be
          furnished to the Claimant.  The decision shall set forth its reasons
          and pertinent Plan provisions on which it is based.  The decision
          shall be final and binding upon the Claimant and the Committee and all
          other persons involved.

10.8 Plan Administration - Miscellaneous
     -----------------------------------

     (a)  Limitations on Assignments
          --------------------------

          Benefits under the Plan may not be assigned, sold, transferred, or
          encumbered, and any attempt to do so shall be void.  The interest of a
          Participant in benefits under the Plan shall not be subject to debts
          or liabilities of any kind and shall not be subject to attachment,
          garnishment or other legal process, except as provided in Section 10.8
          relating to Domestic Relations Orders, or otherwise permitted by law.

     (b)  Masculine and Feminine, Singular and Plural
          -------------------------------------------

          Whenever used herein, pronouns shall include the opposite gender, and
          the singular shall include the plural and the plural shall include the
          singular whenever the context shall plainly so require.

     (c)  Small Benefits
          --------------

          In cases where the Actuarially Equivalent present value of a vested or
          payable benefit is less than or equal to the maximum permissible
          amount under the Code which may be distributed without the consent of
          a Participant or his or her spouse (in 1990, this amount was $3,500),
          the Committee shall direct such present value be paid in a lump sum
          distribution as soon as practical following termination and prior to
          the Annuity Starting Date.  No payment shall be made pursuant to this
          Section 10.8(c) after a Participant's Annuity Starting Date unless the
          Participant and his spouse consent to such payment in a written
          document filed with the Committee.

     (d)  No Additional Rights
          --------------------

          No person shall have any rights in or to the Trust Fund, or any part
          thereof, or under the Plan, except as, and only to the extent,
          expressly provided for in the Plan.  Neither the establishment of the
          Plan, the accrual of benefits under the Plan nor any action of the
          Employer or the Committee shall be held or construed to confer upon
          any person any right to be continued as an Employee, or, upon
          dismissal, any right or interest in the Trust Fund other than as
          herein provided.  The Employer expressly reserves the right to
          discharge any Employee at any time.

     (e)  Governing Law
          -------------

          This Plan shall be construed in accordance with applicable federal law
          and the laws of the State of Washington, wherein venue shall lie for
          any dispute arising hereunder.

                                       37
<PAGE>
 
     (f)  Disclosure to Participants
          --------------------------

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

     (g)  Income Tax Withholding Requirements
          -----------------------------------

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

     (h)  Severability
          ------------

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

     (i)  Facility of Payment
          -------------------

          In the event any benefit under this Plan shall be payable to a person
          who is under legal disability or is in any way incapacitated so as to
          be unable to manage his or her financial affairs, the Committee may
          direct payment of such benefit to a duly appointed guardian, committee
          or other legal representative of such person, or in the absence of a
          guardian or legal representative, to a custodian for such person under
          a Uniform Gifts to Minors Act or to any relative of such person by
          blood or marriage, for such person's benefit.  Any payment made in
          good faith pursuant to this provision shall fully discharge the
          Employer and the Plan of any liability to the extent of such payment.

     (j)  Correction of Errors
          --------------------

          Any Employer contribution to the Trust Fund made under a mistake of
          fact (or investment proceeds of such contribution if a lesser amount)
          shall be returned to the Employer within one year after payment of the
          contribution.  In the event an incorrect amount is paid to a
          Participant or Beneficiary, any remaining payments may be adjusted to
          correct the error.  The Committee may take such other action it deems
          necessary and equitable to correct any such error.

10.9 Domestic Relations Orders
     -------------------------

     Notwithstanding any Plan provisions to the contrary, benefits under the
     Plan may be paid to someone other than the Participant, Beneficiary or
     joint annuitant, pursuant to a Qualified Domestic Relations Order, in
     accordance with Section 414(p) of the Code.  A

                                       38
<PAGE>
 
     Qualified Domestic Relations Order is a judgement, decree, or order
     ("Order") (including approval of a property settlement agreement) that:

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

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

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

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

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

     (f)  specifies the number of payments or period during which payments are
          to be made;

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

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

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

     Payments to an alternate payee pursuant to a Qualified Domestic Relations
     Order may commence after the Participant becomes vested and on or after the
     earlier of (a) the date the Participant attains age 55, or (b) the date the
     Participant is eligible to elect to receive a Vested Termination Benefit.
     The Alternate Payee may elect any form of payment available under the Plan
     at the time benefit payments commence other than a joint and survivor
     annuity, provided that a lump sum form of payment is available only if the
     Alternate Payee's benefit does not exceed $10,000.

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

                                       39
<PAGE>
 
10.10  Plan Qualification
       ------------------

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

10.11  Deductible Contribution
       -----------------------

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

10.12  Payment of Benefits Through Purchase of Annuity Contract
       --------------------------------------------------------

       In lieu of paying benefits directly from the Trust Fund to a Participant
       or his Beneficiary, the Trustee may purchase, with Trust Fund assets, an
       individual annuity contract from an insurance company rated A+ by A.M. 
       Best Company, Inc. which, as far as possible, provides benefits equal 
       to (or Actuarially Equivalent to) those provided in the Plan for such 
       Participant or Beneficiary, but provides no optional form of retirement
       income or benefit which would not be permitted under the Plan, 
       whereupon the liability of the Trust Fund and of the Plan will cease and
       terminate with respect to such benefits that are so purchased and for 
       which the premiums are duly paid.  Such an individual annuity contract 
       may be purchased by the Trustee on a single-premium basis or on the 
       basis of annual premiums Payable over a period of years and may be 
       purchased at any time on or after the Participant's Vested Termination 
       Date, Retirement Date or death to provide the benefits due under the 
       Plan to the Participant or Beneficiary on or after the date of such 
       purchase.

       Any annuity contract distributed by the Trustee to a Participant or
       Beneficiary under the provisions of the Plan shall bear on the face 
       thereof the designation "NOT TRANSFERABLE", and such contract shall 
       contain a provision to the effect that the contract may not be sold, 
       assigned, discounted or pledged as collateral for a loan or as security
       for the performance of an obligation or for any other purpose to any 
       person other than the issuer thereof.

                                   SECTION 11

                           AMENDMENT AND TERMINATION


11.1 Amendment General
     -----------------

     The Employer shall have the right to amend, terminate, or partially
     terminate this Plan by action of its Board of Directors at any time subject
     to any advance notice or other requirements of ERISA.

11.2 Amendment - Consolidation or Merger
     -----------------------------------

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

11.3 Termination of the Plan
     -----------------------

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

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

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

     In the event of a complete Plan termination, the right of each Participant
     to benefits accrued to the date of such termination that would be vested
     under the provisions of the Plan in the absence of such termination shall
     continue to be vested and nonforfeitable; and the right of each Participant
     to any other benefits accrued to the date of termination shall be fully
     vested and nonforfeitable to the extent then funded under the priority
     rules set forth in Section 4044 of ERISA.  In any event, a Participant or a
     Beneficiary shall have recourse only against Plan assets for the payment of
     benefits thereunder, subject to any applicable guarantee provisions of
     Title IV of ERISA.  The Committee shall direct the Trustee to allocate
     Trust assets to those affected Participants to the extent and in the order
     of preference set forth in Section 4044 of ERISA.  The assets so allocated
     shall be

                                       41
<PAGE>
 
     distributed, as determined by the Committee, either wholly or in part by
     purchase of nontransferable annuity contracts or lump-sum payments.  If
     Trust Fund assets as of the date of Plan termination exceed the amounts
     required under the priority rules set forth in Section 4044 of ERISA, such
     excess shall, after all liabilities of the Plan have been satisfied, revert
     to the Employer to the extent permitted by applicable law.

     If at any time the Plan is terminated with respect to any group of
     Participants under such circumstances as to constitute a partial Plan
     termination within the meaning of Section 411(d)(3) of the Code, each
     affected Participant's right to benefits that have accrued to the date of
     partial termination that would be vested under the provisions of the Plan
     in the absence of such termination shall continue to be so vested; and the
     right of each affected Participant to any other benefits accrued to the
     date of such termination shall be vested to the extent assets would be
     allocable to such benefits under the priority rules set forth in Section
     4044 of ERISA in the event of a complete Plan termination.  In any event,
     affected Participants shall have recourse only against Plan assets for
     payment of benefits thereunder, subject to any applicable guarantee
     provisions of Title IV of ERISA.  Subject to the foregoing, the vested
     benefits of such Participants shall be payable as though such termination
     had not occurred; provided, however, that the Committee, in its discretion,
     subject to any necessary governmental approval, may direct that the amounts
     held in the Trust Fund that are allocable to the Participants as to whom
     such termination occurred be segregated by the Trustee as a separate plan.
     The assets thus allocated to such separate plan shall be applied for the
     benefit of such Participants in the manner described in the preceding
     paragraph.

12.1 Contributions to the Trust
     --------------------------

     As a part of this Plan the Employer shall maintain a Trust.  From time to
     time, the Employer shall make such contributions to the Trust as the
     Committee determines, with the advice of its actuary, are required to
     maintain the Plan on a sound actuarial basis.

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

     The Trust is for the exclusive benefit of Participants.  Except as provided
     in Sections 10.7(j) (Correction of Errors), 10.9 (Domestic Relations
     Orders) and 10.11 (Deductible Contributions), no portion of the Trust shall

     As a part of this Plan, the Employer has entered into a trust agreement
     with a Trustee.  The Employer has the power and duty to appoint the Trustee
     and it shall have the power to remove the Trustee and appoint successors at
     any time.  As a condition to exercising its power to remove any Trustee
     hereunder, the Employer must first enter into an agreement with a successor
     Trustee.

12.5 Investment Manager
     ------------------

     The Employer has the power to appoint, remove or change from time to time
     an Investment Manager to direct the investment of all or a portion of the
     Trust Fund held by the Trustee.  For purposes of this section "Investment

                                  FIDUCIARIES


13.1 Limitation of Liability of the Employer and Others
     --------------------------------------------------

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

13.2 Indemnification of Fiduciaries
     ------------------------------

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

13.3 Scope of Indemnification
     ------------------------

     The Employer agrees to indemnify an Employee fiduciary as described above
     for all acts taken in good faith in carrying out his or her
     responsibilities under the terms of this Plan or other responsibilities
     imposed upon such fiduciary by ERISA.  This indemnification for all acts is
     intentionally broad but shall not provide indemnification for embezzlement
     or diversion of Plan assets for the benefit of the Employee fiduciary.  The
     Employer agrees to indemnify Employee fiduciaries described herein for all
     expenses of defending an action by a Participant, Beneficiary or government
     entity, including all legal fees for counsel selected with the consent of
     the Employer and other costs of such defense.  The Employer will also
     reimburse an Employee fiduciary for any monetary recovery in any court or
     arbitration proceeding.  In addition, if the claim is settled out of court
     with the concurrence of the Employer, the Employer will indemnify an
     Employee fiduciary for any monetary liability under said settlement.  The
     Employer shall have the right, but not the obligation, to conduct the
     defense of such persons in any proceeding to which this Section 13.3
     applies.  The Employer may satisfy its obligations under this Section 13.3
     in whole or in part through the purchase of a policy or policies of
     insurance providing equivalent protection.

       THIS TRUST AGREEMENT is known as the Advanced Technology Laboratories,
Inc. Retirement Plan Trust Agreement, and was formerly known as the Westmark
International Incorporated Retirement Plan Trust Agreement (the "Trust
Agreement").

       Advanced Technology Laboratories, Inc. ("Employer") adopted the
Advanced Technology Laboratories Floor Retirement Plan (the "Plan") with an
associated trust effective January 1, 1981.

       The Plan was amended and restated effective January 1, 1987, the name
was changed to the Westmark International Incorporated Floor Retirement Plan,
and Westmark International Incorporated became the plan sponsor, in connection
with the distribution of shares of Westmark International Incorporated to the
shareholders of Squibb Corporation.  The associated trust was amended and
restated as of the same date and renamed the Trust Agreement for Westmark
International Incorporated Floor Retirement Plan.

       The Plan was amended and restated effective January 1, 1990 and the
name was changed to the Westmark International Incorporated Retirement Plan.
The Trust Agreement was not restated at such time.

       The corporate name of Westmark International Incorporated was changed
to Advanced Technology Laboratories, Inc. effective June 26, 1992.  The Plan was
amended and restated, and the name of the Plan was changed to the Advanced
Technology Laboratories, Inc. Retirement Plan.  The Trust Agreement is hereby
renamed and restated effective June 26, 1992.

       The Trustee for the Advanced Technology Laboratories, Inc. Retirement
Plan was changed from Boatmen's Trust Company to First Interstate Bank of
Washington, NA effective December 29, 1993.  The Trust Agreement is hereby
amended and restated effective December 29, 1993.

       The Employer and the undersigned trustee or trustees ("Trustee") intend
that the Plan and Trust will comply with the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), Section 401(a) of the Internal Revenue Code
of 1986, as amended, ("Code") and related Treasury Regulations and that the
Trust qualifies as a tax exempt trust under Section 501(a) of the Code.

       The Employer and the Trustee now enter into this trust Agreement on the
following terms:

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

     The Participating Employers shall pay to the Trustee from time to time

     including the responsibility to authorize and direct the Trustee to make
     all distributions of benefits under the Plan.

3.2  Managing the Trust
     --------------------

     Except as provided otherwise in this Agreement, the Trustee has the
     sole responsibility for the management, acquisition, disposition (for

     the Plan, to the extent such assets are transferred to the Trustee.

3.3  Instructions to Trustee

     of the chairman and members of the Committee to enable the Trustee to act

     accordance with applicable law and the provisions of this Agreement.  The

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

     All or any portion of the Trust may be invested in a collective
     investment fund maintained by the Trustee exclusively for investment of
     funds held in qualified employee benefit trusts.  During such period of
     time as an investment through any such collective investment fund shall
     exist, the declaration of trust of any such fund shall constitute a part of

     The Employer may require the Trustee, upon written notice, to deposit

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

          The investment manager shall be and act as a fiduciary with
          respect to the Trust assets for which it is responsible.  The Trustee
          shall act upon the investment instructions given to it by the
          investment manager with respect to those Trust assets for which such
          manager is responsible, and in so doing the Trustee shall be only an

                                    ------- 

          WHEREAS, the Employee is presently an employee of Interspec, Inc.

          3. Compensation.
             -------------

          (a)  Base Salary.  During the period of his employment during the term
               -----------                                                      
of this agreement, Employee shall receive an annual base salary of not less than
Three Hundred Thousand Dollars ($300,000) (the "Base Salary") which shall be
paid in equal installments in accordance with ATL's regular payroll practices.
The Base Salary may be increased from time to time by the Compensation Committee
of ATL's Board of Directors (the "Compensation Committee").  The Compensation
Committee shall review the Base Salary at least annually.  Any increase in Base
Salary shall not serve to limit or reduce any other obligation to Employee under
this Agreement.  Base Salary shall not be reduced after any such increase and
the term Base Salary as utilized in this Agreement shall refer to Base Salary as
so increased.

          (b) Bonuses.  Employee shall receive an annual bonus of not less than
              -------                                                          
$140,000 for each fiscal year at the time bonuses to other officers of ATL are
paid or payable for such fiscal year as determined by the Compensation Committee
of the Board of Directors of ATL; provided however, that each annual bonus shall
be paid no later than the end of the third month of the fiscal year next
following the fiscal year for which the Annual Bonus is awarded, unless Employee
shall elect to defer the receipt of such Annual Bonus, and provided further that
such Annual Bonus shall be pro rated for the fiscal year in which this Agreement
expires or otherwise terminates.  For purposes of this Agreement, the portion of
the Employee's annual bonus equal to $140,000 shall hereinafter be referred to
as the "Annual Bonus" and the portion, if any, of the Employee's annual bonus in
excess of $140,000 shall hereinafter be referred to as the "Additional Bonus".

          (c)  Fringe Benefits.  The Employee shall be entitled to participate
               ---------------                                                
in the same insurance, vacation and other fringe benefit programs of ATL as are
provided to ATL's other executive officers.  Nothing in this Agreement shall be
construed to prevent ATL from amending its benefit programs from time to time,
including an amendment to eliminate all or any portion of its programs.  The
Employee shall also be entitled to continue to participate in Interspec's
Supplemental Executive Retirement Plan (the "SERP") which is incorporated into
the Merger Agreement; however, the portion, if any, of the benefit accrued by
the Employee under the SERP at his termination of employment which is in excess
of his benefit accrued on the Effective Date shall be reduced (but not below
zero) by the benefits accrued by the Employee after the Effective Date as a
beneficiary under ATL's retirement plans.  In addition, ATL shall provide to
Employee a term life insurance policy in the face amount of $1,000,000 payable
to such beneficiary or beneficiaries as shall be designated by Employee, and a
long-term
<PAGE>
 
                                       3


disability insurance policy providing annual benefits to the Employee
equal to 60% of the Employee's Base Salary in the event of the long-term
disability of the Employee.  ATL shall also provide to Employee the full-time
use of an automobile of a type satisfactory to Employee and substantially
similar to the automobile provided to Employee under his December 23, 1993
employment agreement with Interspec.

          (d)  Equity Compensation.  The Employee shall be eligible to receive
               -------------------                                            
options to purchase ATL common stock and to receive restricted stock awards of
ATL common stock commensurate with those granted to the key employees of ATL.

          (e)  Reimbursement of Expenses.  Employee shall be entitled to incur
               -------------------------                                      
reasonable business expenses in the performance of services for ATL.  ATL will
reimburse Employee for such expenses provided Employee shall complete an
itemized expense report on forms provided by ATL, and furnish the report
together with related receipts to ATL.  If at any time ATL makes advances to
Employee for any purpose, including advances for business expenses or for
personal purposes, Employee hereby authorizes ATL to deduct, withhold, or divert
from his compensation an amount equal to such advances outstanding on his last
day of employment.  If any outstanding advances relate to business expenses
incurred in accordance with this Section of this Agreement, upon submission of a
properly completed and substantiated expense report, ATL will release any
amounts so deducted to Employee.

          (f)  Entire Compensation.  The compensation provided for in this
               -------------------                                        
Agreement is in full payment of the services to be rendered by the Employee to
ATL hereunder.

          4.  Death or Total Disability of the Employee.
              ----------------------------------------- 

          (a)  Death. In the event of the death of the Employee, this Agreement
               -----                                                           
shall terminate effective as of the date of the Employee's death, ATL shall not
have any further obligation or liability under this Agreement except that ATL
shall pay to the Employee's estate:  (i) the portion of the Base Salary earned
by Employee but unpaid for the current or any prior year, prior to the date of
death; and (ii) the pro rata portion of any Annual Bonus and Additional Bonus
which Employee had earned for the current or any prior year, but not received
prior to the date of death; and (iii) any other payments or benefits that the
Employee is eligible to receive under any benefit or retirement plans or other
arrangements that would, by their terms, apply.
<PAGE>
 
                                       4


          (b)  Total Disability.  In the event of the Total Disability (as that
               ----------------                                                
term is hereinafter defined) of the Employee for a period of 90 consecutive
days, ATL shall have the right to terminate the Employee's employment hereunder
by giving the Employee 20 days' written notice thereof, and upon expiration of
such 20-day period, ATL shall not have any further obligation or liability under
this agreement, except that ATL shall pay to the Employee:  (i) the portion of
the Base Salary earned by Employee but unpaid prior to the date of termination;
and (ii) the pro rata portion of any Annual Bonus and Additional Bonus which
Employee had earned for the current or any prior year, but not received prior to
the date of termination; and (iii) any other payments or benefits that the
Employee is eligible to receive under any benefit or retirement plans or other
arrangements that would, by their terms, apply.  Notwithstanding anything to the
contrary set forth in this Section 4(b), the Employee shall continue to be paid
his Base Salary until he becomes eligible to receive benefits under the long-
term disability insurance policy referred to in Section 3(c) hereof.  The term
"Total Disability," when used herein, shall mean a mental or physical condition
which in the reasonable opinion of the Compensation Committee renders the
Employee unable or incompetent to carry out the job responsibilities held or
tasks assigned at the time the condition was incurred, and which entitles
Employee to receive payments under the long-term disability insurance policy
referred to in Section 3(c) hereof.

          5.  Discharge by ATL.
              ---------------- 

          (a)  Discharge for Cause.  ATL may discharge the Employee and thereby
               -------------------                                             
terminate his employment hereunder for the following reasons (hereinafter
referred to as a "discharge for cause"):  (i) the demonstrably willful and
deliberate failure by Employee substantially to perform his material duties and
obligations to ATL under this Agreement (other than a failure resulting from any
illness, sickness, or physical or mental incapacity) which failure continues
after ATL has given notice of the failure to Employee; or, (ii) the demonstrably
willful and deliberate engaging by Employee in misconduct which materially is
injurious to ATL.  In the event that ATL shall discharge the Employee pursuant
to this Section 5(a), ATL shall not have any further obligation or liability
under this agreement, except that ATL shall pay to the Employee:  (i) the
portion of the Base Salary earned by Employee but unpaid prior to the date of
termination; and (ii) the pro rata portion of any Annual Bonus and Additional
Bonus which Employee had earned for the current or any prior year, but not
received prior to the date of termination; and (iii) any other payments or
benefits that the Employee is eligible to receive under any benefit or
retirement plans or other arrangements that would, by their terms, apply.
Notwithstanding the foregoing, the Employee shall have the notice period
provided for in Section 5(e) hereof
<PAGE>
 
                                       5


within which to cure the stated reason for the discharge for cause to the
reasonable satisfaction of ATL.

          (b)  Other Discharge by ATL.  If ATL shall discharge the Employee for
               ----------------------                                          
any reason other than one specified in Section 5(a) above (hereinafter referred
to as a "discharge without cause"), the Employee shall be entitled to receive:
(i) the portion of the Base Salary earned by Employee but unpaid prior to the
date of termination; and (ii) the pro rata portion of any Annual Bonus and
Additional Bonus which Employee had earned for the current or any prior year,
but not received prior to the date of termination; and (iii) any other payments
or benefits that the Employee is eligible to receive under any benefit or
retirement plans or other arrangements that would, by their terms, apply; and
(iv)  a termination payment equal to the Base Salary and Annual and Additional
Bonuses that Employee would have been entitled to receive hereunder after the
date of termination had this Agreement remained in effect through the end of the
term specified in Section 2 above.  At the election of Employee, such amount
shall be payable either in a lump sum or in substantially equal monthly
installments through April 14, 1997.  During the balance of the period ending
April 14, 1997 Employee shall also be entitled to continue to receive fringe and
welfare benefits, described in Section 3(c) above, which are at least comparable
to those to which he was entitled immediately prior to the termination of his
employment, and shall continue to receive service credit for purposes of the
SERP.  If the terms of any welfare benefit plan of ATL does not permit continued
participation by the Employee, then ATL shall arrange to provide to the Employee
a benefit substantially similar to and materially no less favorable than the
benefit he was entitled to receive under such plan at the end of the period of
coverage.  Finally, ATL will permit the Employee during a period of three months
following his termination, upon written request, to execute a cashless exercise
of all outstanding stock options previously granted to the Employee under any
stock option plan maintained by ATL, whether or not such options are then
exercisable, and to have all restricted stock grants and other forms of equity
compensation, whether or not vested, vest immediately.

          (c)  Termination for Good Reason.  The Employee may terminate his
               ---------------------------                                 
employment hereunder for Good Reason (as defined below).  Upon any such
termination, the Employee shall receive from ATL the same salary, bonus and
other payments and employee fringe and welfare benefits that would be payable to
the Employee pursuant to Section 5(b) hereof upon a discharge of the Employee
without cause.  For purposes of this Agreement, the term "Good Reason" shall
mean the occurrence of any of the following events without the Employee's
express written consent:  (i) any failure by ATL to comply with any of the
provisions of Section 3, other than an isolated, insubstantial and inadvertent
failure not occurring in bad faith and which is remedied by ATL promptly after
<PAGE>
 
                                       6


receipt of notice thereof given by Employee; or (ii) ATL's requiring the
Employee to be based at any office or location other than the location where
Employee was employed immediately preceding the Effective Date or any office
which is less than 30 miles from such location; or (iii) the assignment to the
Employee of any duties materially inconsistent in any respect with the
Employee's position (including status, offices, titles and reporting
requirements), authority, duties or responsibilities as contemplated by Section
1 or any other action by ATL which results in a diminution in such position,
authority, duties or responsibilities, excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Employee; or (iv) any purported termination by ATL of Employee's employment
otherwise than as expressly permitted by this Agreement; or (v) any failure by
ATL to comply with and satisfy Section 9; provided that such successor has
received at least ten days prior written notice from ATL or Employee of the
requirements of Section 9.  For purposes of this Section 5(c), any good faith
determination of "Good Reason" made by Employee shall be conclusive.

          (d)  No Mitigation Required.  Upon a termination of the Employee's
               ----------------------                                       
employment by ATL without cause or by Employee for Good Reason, the Employee
shall have no obligation to seek other employment but shall not be prohibited
from doing so, and no compensation paid to the Employee as the result of any
other employment shall reduce any payment required to be made by ATL hereunder.

          (e)  Notice of Termination.  Any termination of the Employee's
               ---------------------                                    
employment by ATL or by the Employee shall be communicated by written Notice of
Termination to the other party hereto in accordance with Section 10 hereof.  A
"Notice of Termination" shall mean a notice which indicates the specific
termination provision in this Agreement relied upon and sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Employee's employment.  The Notice of Termination shall also specify a date
of termination which shall be no earlier than 30 days after the Notice of
Termination is given.

          (f)  No Set-Off.  ATL's obligation to make the payments provided for
               ----------                                                     
in this Agreement and otherwise to perform its obligations hereunder shall not
be affected by any set-off, counterclaim, recoupment, defense or other claim,
right or action which ATL may have against Employee or others.

          6.  Expense Reimbursement; Payment of Disputed Amounts.
              -------------------------------------------------- 
<PAGE>
 
                                       7



          (a)  Expense Reimbursement.  In the event that any person asserts the
               ---------------------                                           
invalidity of all or any part of this agreement and the Employee incurs legal
fees or expenses in connection with defending the validity of all or a portion
of this Agreement, ATL shall reimburse the Employee for all legal fees and costs
the Employee so incurs.

          (b)  Payment of Disputed Amounts.  If there shall be any dispute
               ---------------------------                                
between ATL and Employee (i) in the event of any termination of Employee's
employment by ATL, whether such termination was for Cause, or (ii) in the event
of any termination of employment by Employee, whether Good Reason existed, then,
unless and until there is a final, nonappealable judgment by a court of
competent jurisdiction declaring that such termination was for Cause or that the
determination by Employee of the existence of Good Reason was not made in good
faith, ATL shall pay all amounts, and provide all benefits, to Employee and/or
Employee's family or other beneficiaries, as the case may be, that ATL would be
required to pay or provide pursuant to Section 3 as though such termination were
by ATL without Cause or by Employee with Good Reason; provided however, that ATL
shall not be required to pay any disputed amounts pursuant to this paragraph
except upon receipt of an undertaking by or on behalf of Employee to repay all

CHAIRMAN'S LETTER

Fellow Shareholders,

  ATL faced a challenging and difficult year in 1994. Fundamental
restructuring of the U.S. health care market and soft economic trends in Europe
created unfavorable conditions in our two largest markets. Nevertheless, the
Company made important progress toward its strategic goal of becoming a leader
in all clinical segments of the worldwide ultrasound market. As a result, we
believe we have established the foundation for significantly improved future
financial performance.

  During the year, we broadened our participation in the $2 billion worldwide
ultrasound market through the acquisition of Interspec, Inc., a leading U.S.
cardiology ultrasound company. We now offer a product line that expands our
strong position in the premium performance, general imaging markets to the
large cardiology market as well as to the growing market for high quality,
mid-priced systems.

  In the fourth quarter, we introduced our single most important product advance
to date, the HDI(TM) 3000. ATL's fourth generation all-digital system represents
a decade of investment and clinical leadership in digital ultrasound. The HDI
3000 delivers superior performance, shorter examination times, unparalleled ease
of use and the ability to move easily to wherever it is needed in the hospital.
We believe the HDI 3000 superbly addresses the economic imperatives of the new
health care environment in the United States and international markets.

  Today's worldwide health care market is undergoing sweeping change driven by
economic and political forces. For the past two years, the U.S. ultrasound
market has contracted significantly as hospitals coped with massive
restructuring and consolidation. Federal and state activity on health care
reform created further uncertainty and postponement of some medical equipment
expenditures. For all of its near term turmoil, we believe that the emerging
health care delivery system with its focus on patient outcomes and cost
containment will favor the use of noninvasive technologies such as ultrasound.
With our strong market position and broad product line, we believe that we are
increasingly well positioned to take advantage of this trend. 

  Approximately half of ATL's revenues are generated internationally. We enjoy
a market leadership position in Europe, a region now emerging from its worst
recession in over 20 years. Our expansion into the mid-range market with the
newly acquired Apogee (Registration Mark) products showed strong momentum as we
closed the year. We believe this product line will be a key strategic asset in
1995.

  The Asia Pacific and Latin American markets continued to demonstrate
excellent growth throughout 1994. We opened our first Latin American subsidiary
in Argentina as well as a regional office in Singapore to support growth
throughout Asia. Most recently we reached agreement to increase our equity
position to a majority share in our joint venture in India.
<PAGE>
 
Financial Performance

  The year's financial performance reflected the investments required for the
Interspec acquisition, expansion of international distribution, development and
launch of new products as well as constrained, competitive market conditions.
Worldwide revenues increased 1.6% over 1993 to $366.2 million. Gross margin
declined from 46.0% in 1993 to 44.7% in 1994 due to market pricing pressures.
Operating expenses rose 5.2% to $173.2 million for the reasons noted above. We
had two non-recurring charges totalling $7.0 million for the acquisition of
Interspec and severance costs associated with continuing corporate streamlining
activities. In addition we accrued $5.0 million for ongoing patent litigation
with SRI International, Inc. Excluding these one-time charges, the net loss for
1994 was $8.2 million or $0.62 per share. Including the charges, the loss was
$20.2 million or $1.53 per share. Our balance sheet is strong and continues to
reflect a low level of debt.

  We recently announced plans to consolidate Interspec's operations with those
of our headquarters during 1995. This consolidation will bring important
benefits, saving an estimated $8.0 million annually. We expect to accrue
one-time charges of approximately $5.0 million for employee relocation and
severance expenses in 1995. 
 
Dedicated to Ultrasound

  As the worldwide economy strengthens, demand for improved health care
increases. ATL is leading in opening new frontiers of ultrasound application
that contribute to improved patient care by reducing the need for more
expensive, invasive diagnostic procedures. It is our dedicated focus on
ultrasound that keeps ATL at the forefront of technology development and
challenges us to respond to clinical and diagnostic demands of health care
environments worldwide.

  We would like to thank Ralph M. Barford, who retired from the Board, for his
years of distinguished service to ATL. We welcome new board member Phillip M.
Nudelman, Ph.D., president and CEO of Group Health Cooperative of Puget Sound.
Dr. Nudelman is a nationally recognized expert on the organization and delivery
of cost-effective health care. To ATL employees, I extend my appreciation for
the many contributions throughout the year. We thank you, our shareholders, for
your continued support.

ATL WORLDWIDE

  From the earliest days of medical practice, physicians have sought to
understand and heal the human body while causing no harm. Technologies such as
ultrasound that offer a means of looking into the body with virtually no risk
to the patient have become an essential health care need throughout the world.
Since 1991, ATL's all-digital High Definition/TM/ Imaging (HDI) has stood as a
hallmark of excellence in diagnostic ultrasound. Today, over 3,000 major
medical research institutions, hospitals and clinics worldwide use HDI systems
to better understand and define anatomical structures, disease states, blood
flow and fetal status. Its advanced capabilities are helping to open new areas
of ultrasound diagnosis. The following examples highlight the impressive
potential of ATL's High Definition ultrasound to provide better health care
while reducing its cost. 

      [Graphic: Employees assembling ultrasound units, over background of

Page 4 CAPTION: SEATTLE, WASHINGTON Design and manufacture of HDI 3000 has
achieved certification to the rigorous ISO 9001 international quality standard.

  Appendectomies are one of the most common forms of emergency surgery. Yet
studies have determined that the appendix was normal in 10-20 percent of men
undergoing an appendectomy and in as many as 46 percent of women who are
ovulating. A major factor contributing to these unnecessary surgeries is the
difficulty of confirming--or ruling out--appendicitis, a potentially life
threatening situation. Until recently, ultrasound could not routinely
differentiate appendicitis from other causes of pelvic pain. Now, with the
advanced imaging capabilities of HDI technology, clinicians report they can
successfully evaluate the appendix in almost all cases. Visualizing a normal
appendix significantly reduces the number of unnecessary
<PAGE>
 
appendectomies and allows more accurate diagnosis of the actual underlying
problem.
 
  Vascular surgery is another important area where ATL is contributing to
improved patient outcomes while lowering health care costs. Recent studies have
shown that ultrasound used during vascular surgery can reduce the incidence of
post-operative complications requiring corrective surgery. A new scanhead
introduced by ATL is gaining rapid acceptance in this emerging clinical
application. The miniature, lightweight Entos/TM/ CL10-5 broadband scanhead is
designed to be placed directly on the blood vessel allowing the surgeon to
inspect the technical quality of repairs--and perform a surgical revision
immediately if a defect is identified--prior to closure of the incision. This
not only saves patients the trauma and risk of repeat surgery, but potentially
saves hundreds of thousands of dollars annually in health care costs per
hospital.

  Musculoskeletal injuries--injuries to muscles, tendons and ligaments--affect
tens of thousands of people each year and are difficult to diagnose and treat.
A variety of expensive, invasive diagnostic techniques are currently used to
evaluate these conditions, from magnetic resonance imaging to arthroscopy to
x-ray. Physicians report that ATL's new CL10-5 scanhead can successfully image
the small superficial structures involved in sports medicine and repetitive
motion injuries such as carpal tunnel syndrome--a new capability that could
help launch ultrasound into orthopedic radiology. In addition to its cost
advantages, ultrasound offers the added benefit of displaying function and
blood flow in real time, allowing evaluation of important diagnostic indicators
such as inflammation and subtle soft tissue changes.

worldwide for the noninvasive assessment of cardiovascular disease.
<PAGE>
 
Ultrasound makes possible the dynamic imaging of musculoskeletal anatomy through
its full range of motion, something not possible with other imaging
technologies.

  Breast cancer is a leading cause of death in women worldwide. ATL's work in
women's health continues with the initiation of a breast imaging study in
conjunction with the French government. This study will further assess the
potential of high resolution ultrasound to help differentiate mammographically
indeterminate solid breast lesions, thereby reducing the need for breast
biopsies.

  Surgical breast biopsies are highly invasive, remove an average of 2.4 cubic
inches of tissue, cause scarring and sometimes deform the breast. A high
percentage are found to be benign. The French study is patterned after ATL's
international, multi-site breast study completed in 1993. In that study,
clinical investigators reported that approximately 37 percent of breast biopsies
could potentially be avoided with the adjunctive use of High Definition
ultrasound following a mammogram with indeterminate findings. In 1994, the U.S.
Food and Drug Administration (FDA) granted expedited review to the Company's
Premarket Approval (PMA) application for this new ultrasound indication. ATL is
currently working with the FDA as they review the study. The French study will
add significantly to the science of breast ultrasound imaging with preliminary
findings expected in a year.

A Demanding New Level of Diagnostic Performance

  Health care systems worldwide face increased pressure for both clinical
productivity and diagnostic accuracy. Advances in ultrasound technology are
providing physicians with resolution of anatomical detail that is often
competitive with and sometimes unmatched by more expensive, invasive and time
consuming diagnostic techniques. For reasons of cost and quality, demand for
ultrasound is rising in hospital intensive care units, surgical suites,
<PAGE>
 
emergency rooms and outpatient facilities. As physicians and health care
administrators seek to improve overall patient management, imaging protocols
relying on ultrasound will become more prevalent. These trends are shaping and
changing the use of ultrasound around the world. 

[Graphic: Tennis players highlighting ankle and shoulder joints, over background
                            of Southern Hemisphere]

Page 7 CAPTION: SYDNEY, AUSTRALIA Clinicians report that HDI technology has
the potential to make a major contribution in the management of sports injuries.

  In October 1994, ATL introduced its fourth generation all-digital ultrasound
system, the HDI 3000, a system designed to address the increasingly demanding
requirements of the changing health care environment, now and into the next
century. In clinical meetings attended by over 1,500 leading clinicians in
North America, Europe, Latin America and Asia Pacific, the performance,
usability and mobility of the HDI 3000 were hailed as major advances. The
system incorporates the latest in digital technology with the clinical
experience gained from many millions of HDI examinations performed all over the
world. Its proprietary all-digital architecture enables total software control
of image formation, automatically adjusting over 500 individual parameters for
a selected clinical application. This new capability, called Tissue
Specific(TM) Imaging, decreases patient examination time and assists in
obtaining uniformly excellent diagnostic results from patient to patient.
Clinicians report that the new user interface with its intuitive controls
further enhances productivity by sharply reducing the learning time required
when compared with other high performance systems.

  The HDI 3000 operates at speeds equivalent to the processing power of a
supercomputer, delivering sharper images and more diagnostic data. It weighs up
to one-third less than other premium performance systems, bringing high
performance ultrasound easily and efficiently to the patient's bedside.
Previously, clinicians were often forced to undertake the risk and expense of
transporting critically ill patients to the imaging department, even when
connected to life support systems, to use the best ultrasound equipment.
<PAGE>
 
  The HDI 3000 joined two other important product introductions during the
year, the Apogee 800 and the Access/TM/ Image Management System. The Apogee 800
creates a new class of ultrasound--High Value Imaging. Designed to bring
excellent image quality and clinical versatility at an affordable price, the
Apogee 800 combines premium features, ease of use and mobility. The system can
be configured to address a broad array of clinical needs and has met with
enthusiastic acceptance, especially in international markets. 

  ATL's Access Image Management System addresses the need to reduce operating
costs and improve productivity by electronically networking the ultrasound
department. This ultrasound image management system provides more efficient
printing processes, automated image archival and retrieval, reduced patient
examination times and improved diagnostic consultations within and between
hospitals. Based on an open network architecture, the Access system connects to
many types of ultrasound systems, printers or other image management products.
This advanced connectivity led to an agreement with Eastman Kodak Company to
interface the Access system and Kodak's multi-modality Ektascan Imagelink/TM/
system. Through this agreement, ATL now participates in the market for image
management systems addressing all diagnostic imaging modalities.

Page 8 CAPTION: A range of broadband scanheads gives exceptional clinical
performance.

  The evolution of ultrasound technology continues to unfold at an astonishing
pace. From small village clinics to the most sophisticated medical
institutions, ATL ultrasound is helping physicians deliver the highest quality
care, cost-effectively. Twenty years ago, ATL began shipping its first
ultrasound system, the first pulsed Doppler device for noninvasively measuring
blood flow through the chambers of the heart. Now advances capable of detecting
blood flow in vessels too small to be seen by the naked eye are just on the
horizon. The accelerating contributions to human health of this remarkable tool
appear almost limitless.

                                                     AND RESULTS OF OPERATIONS

MERGER WITH INTERSPEC, INC.

  ATL (the Company) merged with Interspec, Inc. (Interspec), a manufacturer of
diagnostic medical ultrasound systems and transducers headquartered in Ambler,
Pennsylvania, in May 1994. The merger was accounted for as a pooling of
interests business combination. Therefore, the Company's consolidated financial
statements and information reported for periods prior to the merger have been
restated to include Interspec as if the companies had been combined for all
periods presented. 

RESULTS OF OPERATIONS

  The Company operates in the worldwide diagnostic medical ultrasound imaging
systems industry. Like many high-technology electronic medical systems
industries, the ultrasound industry is highly competitive and market demand is
influenced by a variety of factors. These include the introduction of new
technologies which offer improved clinical capabilities and create demand for
new products, the relative cost-effectiveness and clinical utility of competing
technologies, the structure of health-care delivery organizations, government
policies with respect to regulation, reimbursement and containment of health
care costs and the economies and demographics of the countries where the
Company markets its products. ATL sells its products to hospitals, clinics and
physicians worldwide for use in radiology, cardiology, obstetrics and
gynecology, vascular, musculoskeletal and intraoperative applications. Although
ultrasound systems are typically sold based on image quality, Doppler
sensitivity, product reliability, upgradeability, clinical versatility and ease
of use, price competition is an important factor. Changes in the health care
environment in recent years leading to an increased focus on cost containment
as well as slow economic growth in many countries have resulted in increased
competition in the ultrasound industry. 

  The Company's competitive position and financial results are influenced by
fluctuations in foreign currency exchange rates. In 1994, international
revenues accounted for 46% of total revenues, most of which were denominated in
foreign currencies. Some of ATL's competitors are foreign companies whose
production costs are incurred in foreign currencies. As a result, a
strengthening of the value of the U.S. dollar against other major currencies
may adversely impact the Company's competitive position and financial results.
This impact, however, will be partially offset by the translation of operating
expenses incurred in foreign currencies by the Company's international sales
and service operations into U.S. dollars. 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 exchange exposures.

  In 1994, the Company reported a net loss of $20.2 million or $1.53 per
share. The 1994 net loss reflects the depressed U.S. health care market and
soft European economic conditions, higher operating expenses related to new
product development and introduction, and three non-recurring charges totaling
$12.0 million or $0.91 per share discussed later in this report. In 1993, the
Company reported a net loss of $3.3 million or $.24 per share, which included
restructuring expenses of $4.3 million.

</TABLE>
 
  In 1994, revenues increased 2% from 1993 to $366.2 million, primarily the
result of higher service revenues attributable to the growing installed base of
the Company's products and the expansion of its service operations in
international markets. International revenues increased 5% to $167.2 million or
45.7% of total revenues, as sales in the Asia Pacific and Latin America regions
continued to grow. In Europe, revenues decreased slightly from 1993. The
softness of the European economies continued in 1994 and ATL experienced
competitive pressures on unit prices on the Ultramark(TM) 9 and High
Definition Imaging (HDI) products. However, the Company realized benefits from
the integration of Interspec's mid-range Apogee product lines into the Company's
established distribution network in Europe during the second half of 1994 which
partially offset the impact of the competitive price pressures. U.S. revenues
remained nearly flat compared with 1993, as the market for medical equipment
continued to be affected by the uncertainties created by ongoing restructuring
of health care delivery systems and debates over federal health care reform
legislation and associated competitive pressures. 

  In October 1994, the Company introduced the HDI 3000, ATL's fourth
generation all-digital ultrasound system. The HDI 3000 is a high performance,
premium priced system which the Company believes will provide improved
diagnostic performance and clinical productivity in a lighter-weight, more
mobile system. The Company believes this product addresses many of the changing
needs of the diagnostic medical systems market. Revenue shipments of the HDI
3000 began in November 1994.

  In 1993, revenues were $360.5 million, down 5% from the previous year. The
decrease in 1993 revenues primarily reflects the constrained U.S. medical
equipment market discussed earlier, as U.S. revenues decreased 12% from 1992.
International revenues increased 4% from 1992 to $159.7 million or 44.3% of
total revenues with expansion occurring primarily in the Asia Pacific and Latin
America regions. The Company's product mix continued to shift toward the high
performance, premium priced systems included in the HDI product line, which
constituted nearly two-thirds of product sales in 1993.

  Gross profit was $163.6 million in 1994 or 44.7% of revenues. In 1993, gross
profit was $165.8 million or 46.0% of revenues. The reduction in gross profit
reflects lower product margins due to the adverse impact of competitive price
pressures, lower priced configurations and an overall decline in unit volumes.
However, the Company benefited from a favorable change in product mix from the
older Ultramark 4 and Ultramark 9 products to newer products in the Ultramark 9
HDI, HDI 3000, Apogee 800 and CX product families and, during 1994, product
gross margins increased sequentially each quarter. Gross margin on service
revenues continued to increase in 1994 to 37.5% from 35.8% in 1993 and 34.3% in
1992 on improving operating efficiencies.

  Selling, general and administrative (SG&A) expenses for 1994 were $115.6
million, a 4% increase from 1993. The Company continued to expand its
international operations, including the opening of two new direct sales and
service subsidiaries in Argentina and Singapore. The introduction of the HDI
3000 in fourth quarter 1994 also resulted in increased sales and marketing
expenses compared with 1993. In 1993, SG&A expenses decreased slightly to
$110.8 million from the previous year, reflecting the impact of the August 1993
restructuring discussed later, partially offset by the continued growth of
international sales and marketing operations and expenses related to the
introduction of the Extended Signal Processing (ESP) option or upgrade for the
Ultramark 9 HDI system.

  Research and development (R&D) expenses in 1994 increased 10% to $56.4
million or 15.4% of revenue. In 1993, R&D expenses were $51.3 million or 14.2%
of revenue. ATL continues to invest in product development programs to enhance
its position in proprietary and other technologies. Higher R&D expenses, in
part, reflected the development program for HDI 3000. In addition to the
introduction of the HDI 3000 in October 1994, ATL introduced three new
broadband scanheads which expand the HDI system's clinical capabilities: the
Entos CL10-5 intraoperative scanhead for vascular surgery, the P7-4 phased
array scanhead for pediatric cardiology and neonatal imaging, and the
multiplane transesophageal MPT7-4 scanhead for cardiac imaging. Shipments of
the MPT7-4 will begin in 1995. The Company also introduced Color Power
Angio(TM) Imaging, a new color Doppler technology for the detection and
visualization of small vessel blood flow. These product introductions followed
the 1993 introduction of the ESP technology and four new broadband scanheads
for the HDI system.

foreign subsidiaries and forward foreign currency exchange contracts, and
Washington state business and occupation (B&O) tax of $0.7 million. B&O tax is
a gross receipts tax for products manufactured in the State of Washington. In
1993, other expense, net was $2.7 million, including $1.3 million in foreign
exchange losses and $1.1 million for B&O tax. In 1993, other expense, net also
included a $1.1 million gain on the sale of an investment in a third party.

RESTRUCTURING OF OPERATIONS

  As the competitive pressures in the ultrasound market intensified during
1993 and 1994, the Company undertook two restructurings of operations to
streamline processes and improve productivity across all areas of the Company,
including manufacturing, customer service, sales and marketing, engineering and
administration. In the fourth quarter of 1994, the Company reduced its
workforce by approximately 80 full-time and temporary positions, or about three
percent, and reported restructuring expenses of $1.6 million which provided for
severance and outplacement costs. 

  In August 1993, the Company reduced its worldwide workforce by approximately
11%. As a result of this restructuring, the Company reported a charge of $4.3
million which provided for severance and other costs associated with the
restructuring.

  The Company employed 2,630 and 2,492 employees at December 31, 1994 and
1993, respectively, reflecting growth in direct manufacturing,
corporate marketing, the transducer and image management units and
international sales operations.

MERGER AND OTHER COSTS

  The Company incurred non-recurring charges in 1994 of $5.4 million for
merger and other costs. The non-recurring charges included $2.3 million for
legal, accounting, investment advisory, printing and other professional
services; $1.6 million primarily for the consolidation of Interspec's
international personnel and facilities into the Company's operations; and $1.5
million associated with the bankruptcy of Interspec's former distributor in
Italy which resulted in accounts receivable being garnished in a bankruptcy
proceeding.
 
<PAGE>
 
PROVISION FOR LITIGATION CLAIM

  The Company accrued a provision in 1994 of $5.0 million for a litigation
claim. In December 1994, the U.S. Court of Appeals for the Federal Circuit
affirmed a November 1992 partial summary judgment order of a U.S. District
Court in California which determined that the Company infringed a U.S. patent
of SRI International, Inc. related to an electrical circuit alleged to be used
in the Company's Ultramark 4 system and two discontinued products. The patent
has since expired. In a February 1993 press release, SRI stated it is seeking
over $5.0 million in damages. The actual amount of the claim will be determined
by a jury trial in the California District Court scheduled to commence in March
1995. The jury trial will consider the computation of damages and whether the
patent was willfully infringed by the Company. If willful infringement is found
the court may enhance damages by up to three times. Interest will be imposed on
the amount of actual damages found. There are no assurances that the jury trial
will not result in substantial damages against the Company or that such damages
will not be enhanced by the court. The Company believes it has meritorious
defenses to allegations of willful infringement and will continue to vigorously
assert its positions at trial and any subsequent proceedings.

  Investment income decreased in 1994 and 1993, reflecting lower cash balances
available for investment in these periods. This decrease is offset by a
reduction in interest expense in both periods as in May 1994 the Company paid

mortgages utilized by Interspec prior to the merger and repurchased $3.5 million
of 11% subordinated long-term debt in the fourth quarter of 1992.

*1994 Loss includes $12,013 of merger and related costs, restructuring expenses
 and a provision for litigation claim; 1993 Loss includes restructuring
 expenses of $4,275; and 1992 Income includes $4,959 of stock distribution
 expenses and restructuring expenses related to the Distribution of SpaceLabs.
-------------------------------------------------------------------------
 
  The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (FAS
109). Under FAS 109, the provision for income taxes and the effective tax rate
are subject to volatility. Changes in statutory rates and taxable income will
affect the amount of net deferred tax assets which can be recognized under FAS
109 and the related provision for income taxes.
 
  In determining the realizability of deferred tax assets, the Company
assessed its deferred tax liabilities, tax planning strategies and potential
carryback opportunities. 

  During 1994 and 1993, the Internal Revenue Service completed examinations of
the Company for the years 1991 and 1992, and 1989 and 1990, respectively. The
results of the examinations allowed the Company to reduce its liability for
income taxes by approximately $2 million in both 1994 and 1993. The Company
believes it has made adequate provision for income taxes that may become
payable with respect to open tax years.

  The provision for income taxes includes benefits from the utilization of
foreign tax loss carryforwards. U.S. and foreign tax loss carryforwards of
approximately $7.9 million remain at the end of 1994. No benefit has been
recognized for these remaining carryforwards due to uncertainty surrounding
their realization.

</TABLE>
 
  The Company continues to finance its operations primarily with internal
resources, including cash and short-term investments. The Company had $22.9
million in cash and cash equivalents at December 31, 1994 and holds a $5.0
million marketable debt security which matures in 1996. In May 1994, the
Company paid the outstanding balance of Interspec's short-term borrowings at
the time of the merger with ATL. At December 31, 1994, short-term borrowings
represent working capital lines of credit maintained at several of the
Company's foreign subsidiaries to facilitate intercompany cash flow. 
<PAGE>
 
  Cash used by operating activities was $12.0 million in 1994. At December 31,
1994, receivables were $115.9 million, an increase of $14.1 million from
December 31, 1993 due to higher fourth quarter revenues, increased lease
contract receivables which the Company expects to sell to outside funding
sources in 1995, higher installment receivables in South America and higher
unbilled service maintenance contracts. Inventory levels increased in 1994 to
support the introduction of new products.

  In 1994, the Company sold property formerly used as the Company's
manufacturing facility in Germany for $3.2 million. Normal additions to
property, plant and equipment totaled $15.0 million in 1994. Depreciation and
amortization expense for 1994 was $15.9 million.

  Long-term debt at December 31, 1994 was $17.7 million, up $6.1 million from
1993. In December 1994, the Company purchased land and a building adjacent to
the corporate headquarters and main manufacturing plant in Bothell, Washington.
The purchase of the building was financed with an $11.5 million long-term
variable interest mortgage. The interest rate is based on LIBOR plus 1.25%. The
new facility will be used to consolidate operations at the Company's corporate
headquarters campus. In May 1994, the Company paid the $2.8 million outstanding
balance of two mortgages on Interspec facilities. In addition, $0.5 million of
the outstanding subordinated convertible debentures were converted by the
holders into the Company's common shares in December 1994 and $0.2 million was
paid in cash in accordance with the repayment schedule.
 
  In 1994 and 1993, the Company repurchased 22,500 and 794,000 shares,
respectively, of its own common stock in the open market for $13.8 million
under a share repurchase program intended to service the Company's benefit
plans. The Company was authorized in 1993 to purchase up to 1,000,000 shares
under this program, subject to certain criteria.
 
  The Company has occasionally utilized its cash resources to make
acquisitions of technology or small technology-related businesses. The Company
may undertake further acquisitions of technology in the future. 

  In addition to its cash balances, the Company has available unsecured credit
facilities of $25 million, including a committed line of credit of $15 million.
Barring any unforeseen circumstances or events, management expects existing
cash and available credit lines and funds generated from operations should be
sufficient to meet the Company's operating requirements for 1995.

OTHER BUSINESS FACTORS

  Companies in high technology businesses can from time to time experience
difficulty with the availability of technology employed in their products.
While the Company strives to develop alternate sources for the components it
requires and works closely with vendors of specialty items, the Company's
vendors of highly specialized and unique parts such as custom semiconductor
devices can occasionally experience difficulty in the manufacture of products.
Vendors can also experience difficulty in meeting quality standards the Company
requires of its vendors. Such difficulties can lead to long order lead times or
delays in the Company's manufacture of products. Manufacturing efforts can
also be impeded by third party assertions of patent infringement by the
Company's products, such as the litigation claim previously discussed. There
can be no assurance the Company will not be subject to claims of patent
infringement by other parties or that such claims will not require 
the Company to pay substantial damages or delete certain features from its 
products or both.

  The Company is subject to certain laws and regulations of the U.S. Food and
Drug Administration (FDA) regarding the design, documentation, manufacture,
marketing and reporting of the performance of its products. In March 1994, the
Company received the FDA's observations from the follow-up to a routine 1992
inspection, which the Company believes will not lead to further regulatory
action by the FDA. The Company also received observations from a routine FDA
inspection of its Allendale, New Jersey facility, which the Company also
believes will not lead to further regulatory actions by the FDA. The Company's
ability to obtain timely FDA export and new product approvals is dependent upon
the results of such inspections. 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 Company's regulatory compliance programs have been expanded to encompass
verification of the Company's compliance with international standards for
medical device design, manufacture, installation and servicing known as ISO
9001 quality standards. In 1994, four of the Company's five manufacturing
facilities, including its primary facility in Bothell, obtained 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 quality standards will become mandatory in
Europe in 1999. The FDA is in the process of adopting the ISO 9001 standards as
regulatory medical device standards for the United States, and it is
anticipated these standards will be phased in for U.S. manufacturers of medical
devices over a period of time.

SUBSEQUENT EVENT

  On February 15, 1995, the Company announced a new corporate structure that
will consolidate the Interspec operations located in Ambler, Pennsylvania with
the Company's headquarters operations in Bothell, Washington. The consolidation
will result in relocation of Apogee products manufacturing to Bothell, closure
of the Ambler facility and an estimated net reduction of full-time positions of
approximately four percent of the Company's workforce. The Company expects to
incur approximately $5 million in 1995 for employee retention incentives,
severance payments and relocation expenses associated with the consolidation
and plant closure. The Company has preliminary plans to sell the Ambler real
estate, which has a net book value of $7 million, in late 1995 or early 1996
after operations are transitioned to Bothell. The approximate $5 million charge
for consolidation excludes any loss that might be realized on the disposition
of the Ambler real estate.

THE BOARD OF DIRECTORS AND SHAREHOLDERS
ADVANCED TECHNOLOGY LABORATORIES, INC.

  We have audited the accompanying consolidated balance sheets of Advanced
Technology Laboratories, Inc. and subsidiaries as of December 31, 1994 and
1993, and the related consolidated statements of operations, shareholders'
equity, and cash flows for each of the years in the three-year period ended
December 31, 1994. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Advanced
Technology Laboratories, Inc. and subsidiaries as of December 31, 1994 and
1993, and the results of their operations and their cash flows for each of the
years in the three-year period ended December 31, 1994 in conformity with
generally accepted accounting principles.
 
  As discussed in note 1, the Company changed its method of accounting for
investments to adopt the provisions of the Financial Accounting Standards
Board's SFAS 115, Accounting for Certain Investments in Debt and Equity
Securities, at January 1, 1994.

FINANCIAL STATEMENTS
(Dollars in thousands, except per share data)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation 
 
  The consolidated financial statements include the accounts of Advanced
Technology Laboratories, Inc. and its wholly-owned subsidiaries (the Company).
All significant intercompany accounts and transactions have been eliminated in
consolidation.

  As described further in Note 2, the Company merged with Interspec, Inc.
(Interspec) in May 1994. The merger was accounted for as a pooling of interests
business combination. Therefore, the Company's consolidated financial
statements and information reported for periods prior to the merger have been
restated to include Interspec as if the companies had been combined for all
periods presented.

Operations

  The Company develops, manufactures, markets and services diagnostic medical
ultrasound imaging systems worldwide. These systems are used primarily in
radiology, cardiology, obstetrics and gynecology, vascular, musculoskeletal and
intraoperative applications.

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

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 and equipment are depreciated primarily on the
straight-line method over the following estimated useful lives: 
 
        Buildings                    40 years
        Machinery and equipment    3-10 years
 
  Leasehold improvements are amortized over the shorter of their useful lives
or the term of the lease.

Cost in Excess of Net Assets of Businesses Acquired
 
  The cost in excess of net assets of businesses acquired is included in Other
Assets and is amortized on the straight-line method over periods ranging from
six to nine years. 

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 expense, net.

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 generally issued
for a 12-month period and are carried as unbilled receivables from date of
issue until invoiced to the customer in accordance with the terms of the
contract. 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

  In 1993, the Company began a product leasing program for its customers.
Under this program, the Company leases its medical ultrasound imaging equipment
to customers under sales-type leases with terms ranging from two to five years.
The Company currently sells its lease contract receivables to outside parties
on a regular basis, without recourse. Lease contract receivables which have not
been sold as of the balance sheet date are included in Trade Receivables. 

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.
 
Advertising Expenses
 
  Advertising and promotion costs are expensed when incurred. The Company
incurred advertising costs of $4,442, $3,246 and $3,089 in 1994, 1993 and 1992,
respectively.

Income Taxes

  The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (FAS
109). FAS 109 requires recognition of deferred tax assets and liabilities for
the expected future tax consequences of events that have been included in the
financial statements and tax returns. Under this method, deferred tax assets
and liabilities are determined based on the difference between the financial
statement 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.

Pension Plans
 
  Pension costs are funded in accordance with requirements set forth by the
Employee Retirement Income Security Act of 1974.

Financial Instruments

  The Company enters into foreign currency exchange contracts to hedge against
exposure to foreign currency fluctuations associated with intercompany
receivables and payables denominated in foreign currencies. Foreign exchange
contracts generally have maturities of less than one year. Gains and losses
resulting from these instruments are recognized in the same period as the
underlying hedged transactions. At December 31, 1994 and 1993, the Company had
foreign currency exchange contracts totalling $24,646 and $19,500,
respectively. The Company does not use foreign currency exchange contracts or
other derivative financial instruments for speculative or trading purposes. 

  The Company has other financial instruments consisting of cash and
short-term investments, trade receivables, marketable debt security, 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 approximates their carrying amount.
<PAGE>
 
Concentration of Credit Risk

  Financial instruments which potentially subject the Company to credit risk
consist primarily of cash investments, foreign currency exchange contracts and
trade receivables. The Company's investment portfolio is diversified and
consists primarily of investment grade securities that approximate fair market
value. The Company concentrates its foreign currency exchange contracts
primarily with one major U.S. financial institution. Credit loss from
nonperformance by this counterparty is not anticipated. 

  Concentrations of credit risk with respect to receivables are limited due to
the Company's large 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. In response to
market conditions, the Company expanded sales in certain South 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 accounts. The Company believes it has
adequately provided for these risks in the allowance for doubtful accounts.

Investment Securities

  In January 1994, the Company adopted the provisions of Statement of
Financial Accounting Standards No. 115 (FAS 115) which addresses accounting for
certain investments in debt and equity securities. Under FAS 115, the
accounting methodology is based on the classification of marketable debt and
equity securities into three categories: held-to-maturity, trading securities
and available-for-sale. The Company intends to hold its marketable debt
security to maturity and therefore carries the balance at cost as specified by
FAS 115.
 
Per Share Data
 
  Per share data is based on the weighted average number of common shares and
dilutive common share equivalents outstanding. Common share equivalents are
calculated under the treasury stock method and consist of unexercised employee
stock options.

Reclassifications
 
  Certain amounts reported in previous years have been reclassified to conform
to the 1994 presentation.

2. ACQUISITION OF INTERSPEC, INC.

  On May 17, 1994, the Company completed its merger with Interspec. Interspec
develops, manufactures, markets and services diagnostic medical ultrasound
imaging systems and related supplies and accessories for physicians' offices,
clinics and hospitals. To effect the merger, the Company issued approximately
2,593,000 shares of common stock for all of the outstanding common stock of
Interspec, based on an exchange ratio of 0.413 share of the Company's stock for
each share of Interspec stock (Exchange Ratio). The merger was accounted for as
a pooling of interests business combination.
 
  Combined and separate results of operations of ATL and Interspec prior to
the merger are presented below. Intercompany revenues and cost of sales are
eliminated in the combined results.

-------------------------------------------------------------------------------
</TABLE>
 
  Prior to the merger, Interspec reported its financial statements based on a
November 30 fiscal year end. To conform Interspec's financial reporting period
to the Company's December 31 year-end, the results of Interspec's operations
for the one-month period ended March 31, 1994 have been excluded from the
Consolidated Statements of Operations and Cash Flows and accounted for as an
adjustment to retained earnings. Therefore, the Consolidated Statements of
Operations and Cash Flows include 12 months of Interspec's operations for all
years presented. For the one month ended March 31, 1994, Interspec had revenues
of $3,320, costs and expenses of $7,500 and a net loss of $4,180. These results
included $2,148 of expenses related to the termination of dealer arrangements
in countries outside the United States. 

  In the second quarter of 1994, the Company recorded non-recurring charges of
$5,391 for merger and other costs. The non-recurring charges included $2,302
for legal, accounting, investment advisory, printing and other professional
services; $1,561 primarily for the consolidation of Interspec's international
personnel and facilities into the Company's operations; and $1,528 associated
with the bankruptcy of Interspec's former distributor in Italy which resulted
in accounts receivable being garnished in a bankruptcy proceeding. The $5,391
total is reported separately as "Merger and Other Costs".

3. DISTRIBUTION OF SPACELABS MEDICAL, INC.

  On June 26, 1992, the Company (previously named Westmark International
Incorporated) distributed to its shareholders all of the common stock of
SpaceLabs Medical, Inc., a wholly-owned subsidiary, on a one-for-one basis (the
Distribution). The Distribution had the effect of dividing the Company into two
separate, publicly traded companies: Advanced Technology Laboratories, Inc. and
SpaceLabs Medical, Inc. (SpaceLabs).
<PAGE>
 
  The spin-off of a company, such as SpaceLabs, would normally be reported as
a discontinued operation. However, the historical consolidated financial
statements of the Company were retroactively restated to deconsolidate the
financial statements of SpaceLabs to reflect the Distribution. The Company
believes this exception to the usual method of reporting a spin-off is
appropriate given the highly unique circumstances surrounding the relationship
between SpaceLabs and the Company. These circumstances were reviewed with the
staff of the Securities and Exchange Commission. Management believes that
deconsolidation, which presents the historical financial statements of the
Company as if there never had been an affiliation between the Company and
SpaceLabs, is the most meaningful financial presentation. Corporate and
administrative expenses were allocated to the Company and SpaceLabs based on
relative revenues. Management believes this allocation method was reasonable.
Further, management believes that reported expenses, including income taxes,
would not have been materially different had the Company operated as an
unaffiliated entity.

  In connection with the Distribution, the Company made a net contribution of
assets and liabilities to SpaceLabs, which reduced the Company's shareholders'
equity by $28,855. The contribution consisted of $36,212 in cash and $550 in
other assets, offset by the elimination of a $7,907 payable to SpaceLabs. At
June 26, 1992, the payable due to SpaceLabs represented cumulative cash
transfers prior to the Distribution between SpaceLabs and the Company arising
from SpaceLabs' operating and financing activities.

  As part of the Distribution, the Company and SpaceLabs entered into an
Intercompany Tax Agreement that provides for payment to or reimbursement from
SpaceLabs for pre-Distribution tax matters. In 1993, the Company received a net
amount of $1,055 from SpaceLabs under this agreement as a result of the
conclusion of an Internal Revenue Service examination for the years 1989 and
1990. The amount was reported as an increase to shareholders' equity.

  In 1992, the Company incurred a total of $4,959 of non-recurring expenses
related to the Distribution including Stock Distribution expenses of $1,195 for
legal, accounting, investment advisory, printing and other fees; and
Restructuring Charges of $3,764 related to the closure of the Seattle
headquarters' office, severance of certain personnel as a result of the
Distribution and the write down to estimated market value of the Company's
former ultrasound manufacturing facility in Germany. These charges are reported
separately in the Consolidated Statement of Operations.

4. RESTRUCTURING 

  In the fourth quarter of 1994, the Company incurred restructuring expenses
of $1,622 related to a reduction of its workforce by approximately 80 full-time
and temporary positions. In August 1993, the Company incurred a restructuring
charge of $4,275 related to the reduction of its worldwide workforce of
approximately 11%. These restructurings were taken to streamline the Company's
operations and enhance productivity.

  Restructuring expenses include primarily severance, outplacement and other
costs associated with the restructuring of the Company's operations. At
December 31, 1994 and 1993, accrued expenses related to the restructuring of
operations were $1,482 and $562, respectively. No adjustments have been made to
the amounts accrued subsequent to the restructurings.

5. CASH, SHORT-TERM INVESTMENTS AND MARKETABLE DEBT SECURITY
 
  Cash equivalents, short-term investments and the marketable debt security
are stated at cost. For purposes of the statement of cash flows, cash
equivalents are defined as investments with maturities of three months or less
at the date of purchase.
 
  The marketable debt security issued by the U.S. Government matures in 1996
and the Company intends to hold the security until maturity.

  In 1994, the Company sold its former manufacturing facility in Germany for
$3,224 resulting in a $105 gain. In 1994, the Company also purchased a building
and land adjacent to its corporate headquarters and manufacturing plant in
Bothell, Washington. The new facility will be used to consolidate operations at
the Company's corporate headquarters campus. The purchase price of the land and
building of approximately $11,500 was financed with long-term debt. 
Land and buildings with a net book value of $33,128 serve as collateral on
long-term debt.

---------------------------------------------------------------
</TABLE>
 
  Long-term installment receivables represent scheduled monthly, quarterly or
semi-annual payments due from South American customers beyond one year (see
Note 1, Concentration of Credit Risk). Payment terms on extended term
receivables generally range from one to four years and the Company generally
charges interest at rates of 8% to 10%. 
 
  Amortization of intangible assets included in other assets was $1,839 in
1994, $1,607 in 1993 and $1,435 in 1992.

10. SHORT-TERM BORROWINGS
 
  At December 31, 1994, short-term borrowings represent foreign currency
borrowings carrying interest rates ranging from 8% to 12% under lines of credit
maintained by various foreign subsidiaries for working capital purposes. These
credit lines are primarily unsecured or are guaranteed by the parent company.
At December 31, 1993, short-term borrowings also included borrowings on
Interspec's line of credit. The balance on this line of credit was paid in 1994
and the line of credit was not renewed. The weighted average interest rate on
short-term borrowings was 11% and 7% at December 31, 1994 and 1993,
respectively.

  At December 31, 1994, the Company had available unsecured credit facilities
totaling $25,000, including a committed line of credit of $15,000. No
borrowings were outstanding under these facilities at December 31, 1994. The
loan agreement for the committed line of credit includes various covenants
relating to financial ratios and restrictions on cash dividends. The Company
was in compliance with or had obtained waivers for these covenants at December
31, 1994.
 
  Interest expense as reported in the Consolidated Statements of Operations
approximates amounts paid each year.

</TABLE>
 
  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 actuarial present
value of the projected benefit obligation was 8.5% for 1994, 7.75% for 1993 and
8.5% for 1992. The assumed annual rate of increase in future compensation
levels was 9% for the first five years of service and 5.75% thereafter. The
expected long-term rate of return on plan assets was 9% in each of 1994, 1993
and 1992.
 
  A 401(k) retirement savings plan is maintained for all U.S. employees. The
Company's contributions to this plan were $1,025, $895 and $748 in 1994, 1993
and 1992, respectively.
 
  In 1994, the Company established a profit sharing plan which provides for
employee incentive awards when pre-tax return on sales exceeds 7%. No awards
have been made under this plan.

14. SHAREHOLDERS' EQUITY

  The Company has the following stock plans: the 1992 Option, Stock
Appreciation Right, Restricted Stock, Stock Grant and Performance Unit Plan and
the 1992 Non-Officer Employee Stock Option Plan (the 1992 Plans), the 1986
Management Incentive Plan and the 1993 Non-Employee Director Stock Option Plan.
Under the 1992 Plans, 2,300,000 common shares are reserved primarily for
issuance of stock options at prices equal to the fair market value of the
Company's common shares at the date of grant and for issuance of restricted
shares at par value. Stock options and restricted stock granted under the 1992
Plans are generally exercisable at 25% each year over a four year vesting
period. At December 31, 1994, approximately 212,000 shares were available for
grants under the 1992 Plans.

  Under the 1986 Management Incentive Plan, 100,000 common shares were
authorized for issuance of stock under the Company's management incentive
plans. Approximately 14,000 common shares were issued under this plan in 1994.
At December 31, 1994, approximately 71,000 shares were available for grants
under this plan.

  Under the 1993 Non-Employee Director Stock Option Plan, 50,000 common shares
were reserved for issuance of stock options at prices equal to the fair market
value of the common shares at the date of grant. At December 31, 1994,
approximately 34,000 shares were available for grants under this plan.
 
  In connection with the merger, all Interspec stock options held by Interspec
employees were adjusted, based on the Exchange Ratio, to the Company's stock
options resulting in the issuance of 232,500 options from the 1992 Plan.
 
  The following table summarizes option activity (shares in thousands).

  In 1994 and 1993, 99,000 and 33,000 shares, respectively, of restricted
stock were issued at par value under the 1992 plans. Deferred compensation
representing the fair market value of the shares at the date of grant is
amortized over the vesting period (typically two to four years).

  In February 1993, the Company's Board of Directors authorized a plan to
repurchase up to 1,000,000 shares of its own common stock in the open market,
subject to certain criteria, to be used in servicing the Company's benefit
plans. The Company repurchased 22,500 shares totaling $369 in 1994 and 794,000
shares totaling $13,441 in 1993 under this program.

  At December 31, 1994, the Company had net operating loss carryforwards for
statutory purposes of approximately $7,900, which begin to expire in 1998 or
have no expiration date. The Company also has U.S. research and experimentation
credit carryforwards of approximately $6,600 with expiration dates from 1997
through 2008. Utilization of approximately $4,000 of net operating loss
carryforwards and $2,400 of research and experimentation credit carryforwards
are subject to certain members of the U.S. consolidated group having future
taxable income.

  During 1994 and 1993, the Internal Revenue Service completed examinations of
the Company for the years 1991 and 1992, and 1989 and 1990, respectively. The
results of the examinations allowed the Company to reduce its liability for
income taxes by approximately $2,000 in both 1994 and 1993. The Company
believes it has made adequate provision for income taxes that may become
payable with respect to open tax years.

  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 $1,700. These earnings, which are anticipated to be reinvested,
could become subject to additional tax if they were remitted as dividends, lent
to the Company, or if the Company should sell its stock in these subsidiaries.

16. OTHER EXPENSE, NET

  Other 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
$144, $1,259 and $1,839 in 1994, 1993 and 1992, respectively.

  Other expense, net, also includes Washington State Business and Occupation
taxes of $744, $1,086, and $1,144 in 1994, 1993 and 1992, 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.
 
  In 1993, the Company sold its equity investment in a third party for $3,235.
A gain on the sale of the investment of $1,125 is included in other expense,
net.

18. LEASES

  The Company was obligated at December 31, 1994 under long-term operating
leases for various types of property and equipment, with minimum aggregate
rentals totaling $14,375 as follows: $3,847 in 1995, $3,159 in 1996, $2,532 in
1997, $2,184 in 1998, $1,756 in 1999 and $897 in later years.

  Many of the Company's leases contain renewal options and clauses for
escalations 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 $5,276, $4,882 and $4,838 in 1994, 1993 and 1992, respectively.

19. LEGAL CONTINGENCIES

  In December 1994, the U.S. Federal Circuit Court of Appeals affirmed a
decision of the District Court in California granting a motion by SRI
International, Inc. (SRI) for partial summary judgment on a patent infringement
claim relating to an electrical circuit alleged to be used in the Company's
Ultramark 4 system and two discontinued products. The SRI patent expired in
April 1994. SRI has stated in a February 1993 press release that it is seeking
over $5 million in damages. The District Court has scheduled a jury trial to
commence on March 21, 1995 on the issues of damages and willful infringement.
If the jury returns a verdict of willful infringement the judge may at his
discretion grant an enhancement of damages of up to three times the amount
actually determined. Interest will be applied to actual damages. The Company
will vigorously assert its positions on these issues. At this stage of the
litigation, the Company cannot predict the outcome of the suit or estimate the
amount of loss, but believes its defenses are meritorious and will continue to
vigorously pursue its rights at trial and in any subsequent proceedings. There
are no assurances that the jury trial will not result in substantial damages
against the Company or that such damages will not be enhanced by the court. A
provision for the litigation claim was accrued in the fourth quarter of 1994
for $5,000.

  In addition to the foregoing proceedings, the Company is involved in various
other 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.

</TABLE>
 
  Quarterly per share data shown do not add to the total in 1994 due to
changes in the number of weighted average shares outstanding during the year.

  The 1994 results include non-recurring expenses totaling $5.4 million
associated with the acquisition of Interspec during the second quarter and $6.6
million for the restructuring of operations and a provision for litigation
claim in the fourth quarter. The 1993 results include a restructuring charge of
$4.3 million related to the restructuring of operations in the third quarter.

22. SUBSEQUENT EVENT 

  On February 15, 1995, the Company announced a new corporate structure that
will consolidate the Interspec operations located in Ambler, Pennsylvania with
the Company's headquarters operations in Bothell, Washington. The consolidation
will result in relocation of Apogee products manufacturing to Bothell, closure
of the Ambler facility and an estimated net reduction of full-time positions of
approximately four percent of the Company's workforce. The Company expects to
incur approximately $5 million in 1995 for employee retention incentives,
severance payments and relocation expenses associated with the consolidation
and plant closure. The Company has preliminary plans to sell the Ambler real
estate, which has a net book value of $7 million, in late 1995 or early 1996
after operations are transitioned to Bothell. The approximate $5 million charge
for consolidation excludes any loss that might be realized on the disposition
of the Ambler real estate.
