                                     PART I
 
                                ITEM 1. BUSINESS
 
Spacelabs Medical, Inc. and its wholly owned subsidiaries ("Spacelabs Medical"
or the "Company") develop, manufacture, market and service patient monitoring,
diagnostic cardiology and clinical information systems ("CIS") products for use
throughout the healthcare enterprise. Spacelabs Medical's principal products are
used for diagnosis, monitoring and information management across the healthcare
continuum. The Company also sells the disposable and replaceable supplies to
support these products.
 
Spacelabs Medical's strategy has three key elements: first, to transition into
the emerging CIS market; second, to expand its presence in international
markets; and third, to enhance its position in the US healthcare market through
the expansion of its medical device product line and distribution channels.
 
The first element of the Company's strategy is to move into the emerging CIS
market. One aspect of this is to capitalize on the Company's large installed
base of monitoring systems to transition into the critical care CIS market with
its Chartmaster(TM) CIS. A second aspect of this strategy is to broaden the
Company's CIS offering through acquisitions and joint ventures. In 1997, the
Company acquired or entered into relationships with a number of companies to
enhance its CIS product line. The acquisition of Ameritech Knowledge Data, Inc.
("AKD") added both a clinical data repository ("CDR") and a master patient index
system. A marketing agreement with Tempus Software, Inc. ("Tempus") added a
resource scheduling system which is being integrated with the Company's
Caremaster(TM) system. The acquisition of a CIS product developed by Orca
Medical Systems, Inc. ("Orca") added a departmental system for the emergency
department. The addition of these product lines helped the Company build a
point-of-care-based CIS that supports management of the care process throughout
the enterprise and in both monitored and nonmonitored areas of the hospital.
 
The second element of the Company's strategy is to expand its efforts to
penetrate international markets. While there are many similarities among various
national markets, the Company believes that most national markets must be
approached on an individual basis. An individualized approach includes not only
product-related requirements such as regulatory approvals, user interfaces and
documentation in the local language, but also requires investment in the
creation of distribution channels and in the establishment of a base of
satisfied customers.
 
The third element of this strategy reflects the ongoing challenge to maintain
technological leadership in critical care monitoring and to expand the Company's
presence in the medical device marketplace. To maintain and enhance its
competitive position, the Company believes that it must provide products for
more areas of the device market through continued development of new and
clinically useful products as well as through strategic acquisitions and
alliances. During 1997, the Company completed the acquisition of Advanced
Medical Systems, Inc. ("AMS") and Burdick, Inc. ("Burdick"), made an investment
in Bunnell, Incorporated ("Bunnell") and entered into an agreement with Medical
Insight R & D, B.V. ("Medical Insight"). Through the acquisition of AMS, the
Company added a line of fetal monitors. Burdick added diagnostic products for
the hospital and primary care market as well as distribution for other Spacelabs
Medical products into the primary care market. The Bunnell investment added the
option of distributing a ventilator into the neonatal market and the agreement
with Medical Insight provided the worldwide rights to market an anesthesia
delivery system. The Company also believes that it must maintain strong sales,
marketing and service organizations that compete effectively.
 
HISTORY
 
Spacelabs Medical was founded in 1958 to collaborate with NASA in developing
technology to monitor the vital signs of astronauts in space. By the mid-1960s,
the Company was developing vital sign monitoring systems for use in hospitals,
and in 1968, it introduced its first system for monitoring patients in intensive
care units. Its technological innovations include the first monitors using
distributed microprocessors and the first modular monitors. Between 1980 and
1992, Spacelabs Medical was a
                                        1
<PAGE>   4
 
wholly owned subsidiary, first of the Squibb Corporation ("Squibb") and then of
a 1987 spin-off from Squibb, Westmark International Incorporated ("Westmark").
Effective June 26, 1992, Spacelabs Medical became a separate publicly traded
company pursuant to the distribution by Westmark of Spacelabs Medical common
stock to holders of Westmark common stock in a tax-free, one-for-one stock
dividend. In 1995, the Company sold the First Medic line of nonhospital
defibrillator products to Physio Control International Corporation. In 1996, the
Company acquired JRS Clinical Technologies, a clinical information company. In
1997, the Company acquired AMS, AKD, Burdick and a software product developed by
Orca.
 
PRINCIPAL MARKETS
 
Critical Care Monitoring. The critical care monitoring market in hospitals and
elsewhere comprises adult intensive care units, neonatal intensive care units,
operating rooms and other associated interventional areas such as recovery
rooms, emergency departments, cardiac catheterization labs or endoscopy rooms
and step-down units.
 
Adult critical care units such as coronary care units and surgical intensive
care units are characterized by, among other things, labor-intensive staffing,
sometimes with a one-to-one or often with a one-to-two nurse-to-patient ratio.
 
Over the last decade, hospitals have increasingly used telemetry step-down units
where patients at risk are still monitored but do not require the high level of
nursing care found in intensive care units. There also has been a more recent
trend to use portable monitors in other acute care areas of the hospital when
temporarily needed by individual patients. This temporary monitoring approach
may have cost advantages and allows patients to be monitored without moving them
to an intensive care unit.
 
Perinatal and pediatric intensive care requires monitors with specialized
functionality because of the differences between monitoring a critically ill
newborn or child and a critically ill adult. These differences are a major
factor in choosing a monitor for neonatal intensive care units ("NICUs") or
pediatric intensive care units.
 
Specialized monitors are used for fetal monitoring during pregnancy, labor and
delivery. These monitors may also display information about the mother. The
information from these monitors may be sent to a labor and delivery central
station or be entered manually into the birth record.
 
Perioperative and emergency monitoring in operating rooms, recovery rooms or
emergency departments has traditionally used stand-alone or portable monitors
but is turning to networked monitors as information systems become more
prominent. Surgery was once primarily an inpatient procedure utilizing very
sophisticated monitors in hospital operating rooms. Now more than half of all
surgeries are performed as outpatient procedures, increasing the demand for
simpler, noninvasive monitors.
 
Diagnostic Cardiology. Diagnostic cardiology products are marketed to both acute
care facilities (hospitals) as well as to the alternate and primary care markets
(all nonhospital facilities including physician's offices and clinics).
 
Typically hospitals will have a cardiology or cardiopulmonary department that
performs diagnostic cardiology procedures using these types of products. The
test will be performed by trained technicians and the results of the test will
be read and interpreted by a cardiologist. The department may perform ECG
procedures for outpatient as well as inpatient needs. It is not uncommon for
departments other than cardiology, such as emergency or intensive care units, to
purchase an electrocardiograph to ensure rapid response time when there is a
requirement for an electrocardiogram.
 
In the primary care market the traditional purchasers of diagnostic cardiology
products have been family, general and cardiology practices.
 
Clinical Information Systems. Spacelabs Medical believes that the traditional
market for vital signs monitoring is evolving into one that integrates CIS into
the critical care monitoring system and that with the right design, patient
monitoring systems can be the architectural base for critical care CIS. In
addition, the Company believes that computerization of collected patient
information on an electronic
                                        2
<PAGE>   5
 
patient chart allows a caregiver to spend more time directly attending to
patient needs and that computerization of routine but essentially clerical tasks
enhances clarity and accuracy.
 
Developing an information management system to store, retrieve and interrelate
the information in clinically meaningful ways is a significant challenge.
Customer expectations are also evolving due to provider restructuring as the
result of managed care. One of the clearest needs emerging is for patient-
focused systems that permit caregivers to view and manage the patient care
process across the continuum of care. The Company believes that the market for
enterprise-wide CIS to schedule resources, automate data collection and
retrieval and analyze outcomes is larger than the market for departmental
systems. Thus, while there is still a need for the specialized functions of
information management in a departmental context, there is also a need to
integrate such an application within the context of all episodes of care.
 
SPACELABS MEDICAL'S PRODUCTS
 
Spacelabs Medical develops, manufactures, markets and services critical care
monitoring and CIS products, as well as other products for use in the healthcare
industry. Spacelabs Medical's principal products are its Patient Care
Information System ("PCIS")(TM) line of products, both as an entire system and
in its component parts. The PCIS product line includes both the Company's long-
established Patient Care Monitoring System ("PCMS")(TM) monitoring products and
its evolving Intesys(R) clinical information products.
 
PCMS MONITORING PRODUCTS. Through integration of its component elements,
Spacelabs Medical's PCMS product line forms an advanced and comprehensive
critical care patient monitoring system and the foundation for a CIS. PCMS
products address the hospital's principal monitoring needs, from adult and
neonatal intensive care units to outpatient surgery, step-down units and patient
transport. The components of the PCMS system are "user friendly" bedside and
central monitors, "smart" plug-in modules for measuring specific vital signs,
Flexport(R) serial interfaces to other manufacturers' bedside devices, an
integrated telemetry option and a powerful network for access to clinical
information. Spacelabs Medical sells PCMS products as an integrated system, as
stand-alone monitors or as add-on components to the customer's existing systems.
Sales of PCMS products to hospitals vary widely in size, depending on the size
and configuration of the system. A typical eight-bed hardwired system sells for
approximately $170,000 while a typical 12-bed telemetry system sells for
approximately $85,000. Hospitals sometimes combine monitoring orders for many
units or even for the entire hospital. Such orders can exceed $1 million. PCMS
monitoring products, which first began shipping in 1985, represent the major
portion of Spacelabs Medical's current business.
 
PCMS Bedside Monitors. The critical care bedside monitor, the core of any PCMS
system, is connected to the patient via sensors, electrodes or cuffs. The
bedside monitor displays, stores and transmits vital signs and physiological
data, including alarms, thereby providing an ongoing picture of a patient's
condition. PCMS bedside monitors include the PC Scout(TM), a small portable
monitor; the PC Ranger(TM), a wireless networked monitor; the SL1050, a
mid-range color monitor; and the Universal Clinical Workstation ("UCW")(TM),
which serves not only as an advanced PCMS bedside monitor but also as a computer
terminal and is available both in wireless or hardwired network configurations.
 
PCMS Modules. The clinician can easily configure the PCMS bedside monitor to
meet the specific vital sign monitoring needs of an individual patient by
inserting PCMS modules designed to perform different monitoring functions. These
"smart" modules contain their own processors and software programs and therefore
add computer power to the PCMS monitor. The modules collect and analyze the
patient's physiological data from electrodes and sensors. The Company's newest
modules include the 12-lead ECG and the Bispectral Index(TM).(1)
 
Flexport(R) Serial Interfaces. Spacelabs Medical's Flexport serial interfaces, a
Spacelabs Medical innovation, extend the concept of modules to other
manufacturers' bedside devices. With a Flexport

interface, the PCMS monitor receives and displays data from other devices much
as if it were generated by a Spacelabs Medical module. Thus, the monitor can
integrate vital patient information and alarms onto a single screen to
facilitate clinical decision making.
 
PCMS Telemetry. For step-down units, Spacelabs Medical provides its PCMS
telemetry monitoring systems, which continuously monitor patients' ECGs while
allowing them the freedom to move about as part of the recovery process. By
including telemetry monitors on the PCIS network, hospitals can combine, in the
same care unit, patients requiring different levels of care.
 
PCMS Central Station Monitors. PCMS central station monitors are the same
hardware as the UCW bedside monitors and share the same fundamental, easy-to-use
human interface and mode of operation.
 
DIAGNOSTIC CARDIOLOGY PRODUCTS. In 1997, Spacelabs Medical acquired Burdick to
expand its product offering further across the continuum of care to include both
hospital and primary care out-of-hospital settings. Noninvasive diagnostic
cardiology devices and management systems that Burdick has distributed into the
primary care market also have application in the hospital environment and will
be sold by the Spacelabs Medical hospital sales force. The Burdick sales
organization will continue to sell its current line of cardiopulmonary products
including ECG, exercise tolerance test systems, Holter and spirometry products
into the primary care market and will also add certain diagnostic products from
the Spacelabs Medical product line such as ambulatory blood pressure systems and
fetal monitors.
 
Electrocardiographs. The Company's line of electrocardiographs covers all price
points and markets and ranges from small, low-cost units that are primarily
targeted for physician's offices and international markets to fully featured
units that are designed for the most rigorous application as in the care of
critically ill patients in hospital settings. Electrocardiographs are usually
cart-mounted so that they can be moved from bed to bed or room to room.
 
Holter and Ambulatory Blood Pressure Systems. Spacelabs Medical develops,
manufactures, markets and services Holter and ABP monitoring systems. The Holter
systems comprise ECG recorders (tape or solid state) that are worn by a patient
for 24 or 48 hours. The data is then downloaded to an analysis station that
processes the recorded ECG data. ABP monitors gather a patient's blood pressure
measurement over 24 or 48 hours. This data is then "read" by an analysis station
that quantifies the data and prepares reports for physicians. The recorders are
the smallest and lightest available. Report generation capabilities range from
simple, easy-to-use strip printers to a Windows-compatible software system.
 
Exercise Tolerance Test Systems. Exercise tolerance test systems are diagnostic
cardiology products used to identify latent heart disease not revealed on a
routine resting ECG. The patient is subjected to increasing workloads, typically
on a treadmill, and the cardiogram is monitored for adverse changes in the
heart's response during the increased workload. The product line also includes a
quiet treadmill designed for maximum patient safety.
 
INTESYS(R) CLINICAL INFORMATION SYSTEMS. Spacelabs Medical develops,
manufactures, licenses, sells and supports CIS. In 1995, the Company
consolidated its CIS products under the name Intesys. Intesys CIS form an
integrated framework to automate, manage and analyze the delivery of care.
Spacelabs Medical believes that CIS creates a powerful tool for providing more
efficient and effective patient care. The Company also believes that its
substantial monitoring installed base provides it with a competitive advantage
over other manufacturers' nonintegrated approach to critical care CIS.
 
Chartmaster Clinical Information Systems. This is Spacelabs Medical's
departmental information system product line. With these systems, data is
automatically collected from patient monitors, including data from other
vendors' devices integrated through Flexport serial interfaces. In addition to
maintaining flow sheets, other charting functions are computerized, such as
making notes and observations and charting laboratory results. The Chartmaster
computer system has been designed to be interfaced with other hospital
information systems. The UCW, or another computer workstation at the patient
site or elsewhere on the network, can function as a terminal to enter and review
data on the
 
                                        4
<PAGE>   7
 
Chartmaster record. There are currently departmental applications for adult,
pediatric and neonatal intensive care, the emergency department, anesthesia,
cardiology and labor and delivery.
 
Caremaster Clinical Information Systems. Caremaster CIS are for use throughout
nonmonitored areas of the healthcare enterprise. The main components of the
system are automated order entry and results reporting, a resource scheduler to
help organize appointments throughout the enterprise, a clinical pathways and
automated point-of-care system for support of multidisciplinary clinical
pathways and comprehensive documentation, a CDR to integrate information from
clinical and administrative systems and a master patient index to address the
problem of patients being identified differently by disparate systems. The
enterprise-wide (Caremaster) CIS market is characterized by a sales cycle of up
to two years. Once a system is sold, an extensive period of implementation may
be required before customer acceptance and final payment to the Company occurs.
 
Quality In Care Software. The Quality In Care ("QuIC")(2) software application
is a cross-patient analytical tool that helps administrators and clinicians
analyze clinical practice and make critical decisions regarding the quality and
effectiveness of intensive care from clinical and cost perspectives.
 
While the Intesys products appear to be designed to meet the needs of the
evolving healthcare provider industry, there can be no assurance that Intesys or
its components will fully satisfy user requirements and result in significant
commercial sales.
 
MEDICAL SUPPLIES. A substantial market exists for disposable supplies such as
patient electrodes, specialty graph paper, sensors and connecting lead wires
that are used with medical devices. Spacelabs Medical sells a broad line of such
supplies as an adjunct to its medical device business. In most cases these
products are obtained from original equipment manufacturers and are manufactured
to Spacelabs Medical's specifications. In some cases, Spacelabs Medical
re-markets other manufacturers' products for use with Spacelabs Medical's
products.
 
OTHER PRODUCTS. Spacelabs Medical also develops, manufactures, markets and
services health screening products and services.
 
Health Screening Products and Services. The Company's Vita-Stat subsidiary is
one of the leading US providers of consumer health screening products and
services. Automated equipment for blood pressure measurement and for
cardiovascular risk profiling and weight management are placed by lease or other
arrangement in pharmacies, work sites, hospitals, health clubs and other public
access locations. This business has grown to include point-of-sale advertising
at blood-pressure-based consumer health centers located in approximately 10,000
pharmacies and grocery stores nationwide.
 
RESEARCH AND DEVELOPMENT
 
Spacelabs Medical conducts extensive research and development activities, both
internally and by funding projects undertaken by outside groups. Such activities
include the design and development of new products for its patient monitoring
systems, diagnostic cardiology products and CIS. Spacelabs Medical is
continuously seeking ways to improve its product line and enhance the
functionality of its patient monitoring and CIS. This process of improvement
offers the opportunity for additional revenue from upgrades and the sale of new
functions and features. In 1997, research and development expenses excluding
in-process research and development relating to acquisitions were $31.6 million,
or 11.9% of revenue. In 1996, on the same basis, research and development
expenses were $28.3 million, or 11.4% of revenue, compared to $30.1 million, or
11.9% of revenue, in 1995. See Item 7, "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Operating Expenses."
 
Although Spacelabs Medical intends to continue to conduct 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 Spacelabs Medical's existing technology will not be superseded by new
discoveries or developments.
 
MANUFACTURING
 
Spacelabs Medical manufactures the majority of its products in Redmond,
Washington. The Company's Burdick diagnostic cardiology products are
manufactured in Milton, Wisconsin and the fetal and obstetrical management
products are manufactured in Hamden, Connecticut. The Company conducts regular
product reviews to reduce manufacturing costs and continually pursues
improvement programs to eliminate waste and redundancy.
 
Certain devices are purchased from third parties for sale by Spacelabs Medical,
including computers, peripheral accessories and remote displays. The Company
also purchases subassemblies, such as display screens and printer mechanisms,
and other materials and component parts used by Spacelabs Medical in the
manufacture of its products. Many of these are available from multiple supply
sources. Spacelabs Medical does depend, however, on certain single-source
vendors for some important component parts. 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 the Company's
manufacturing production of the products relying on such items. In addition,
component parts of certain of the Company's products are manufactured in Taiwan,
a country that has periodically experienced political pressure from other
countries, which could delay or disrupt the supply of these component parts.
Spacelabs Medical cannot predict whether there is a substantial likelihood of
abrupt disruption in the supply of any of these items. However, it has taken
steps to mitigate the effect of disruption in the supply of some items by either
maintaining an inventory of certain critical components or locating another
source of certain parts that would be available in the event of an interruption
of supply.
 
SALES AND MARKETING
 
Spacelabs Medical's hospital products are marketed in the United States
primarily through its own direct sales organization. The Company's direct field
sales force consists of sales personnel and clinical application specialists
located throughout the United States. Products sold into the primary care market
are sold through dealerships supported by a direct sales organization. Spacelabs
Medical frequently contracts for the sale of its products with hospital buying
groups, proprietary hospital chains and US government agencies. These "corporate
accounts" can generate multimillion dollar contracts, and the Company believes
that the loss of a major contract could have a material adverse effect on its
operations.
 
Spacelabs Medical markets its products in over 100 countries through a
combination of direct sales organizations and independent distributors.
International sales, service and sales administration activities are managed
from the Company's corporate offices and through subsidiary offices located in
Australia, Austria, Belgium, Canada, China, France, Germany, Hong Kong, India,
Italy, Mexico, the Netherlands, Singapore, Spain, Sweden, Taiwan and the United
Kingdom. International sales are broadly distributed worldwide so that
disruption of distribution in any single foreign market would not have a major
effect on Spacelabs Medical's total annual revenue. Sales to foreign customers
including export sales accounted for approximately 34.2% of Spacelabs Medical's
revenue in 1997. See Note 17 of "Notes to Consolidated Financial Statements."
 
In addition to direct and distributor sales to end users, Spacelabs Medical also
sells its ABP monitors, Holter recorders, noninvasive blood pressure products
and other products and components for distribution by other medical products
companies.
 
Spacelabs Medical's marketing efforts include the development of relationships
with current and prospective customers, participation in annual professional
meetings for clinicians and hospitals, advertisement in trade journals, direct
mail and telephone marketing.

CUSTOMER SUPPORT AND WARRANTY
 
Spacelabs Medical warrants most of its new products (exclusive of software) for
all parts and labor generally for the earlier of 14 months from the date of
original delivery or 12 months from first on-line operation. Under the terms of
the warranty, the customer is assured of service and parts so that the equipment
will operate in accordance with specifications. Spacelabs Medical warrants that
software will perform in accordance with specifications at the delivery date and
up to five months thereafter if the customer gives notice of any nonconformance.
Spacelabs Medical offers a variety of post-warranty service agreements that
permit customers to contract for the level of equipment maintenance they
require. In addition, Spacelabs Medical offers specific software support
agreements, reflecting the growing use in Spacelabs Medical's products of
software that can be updated. Service is provided at rates competitive with
those offered by Spacelabs Medical's competitors. Software licenses for Intesys
products generally have a shorter warranty period and require software support
agreements. Burdick new products are warranted, inclusive of software, for all
parts and labor during the warranty term, which may be one year, three years or
five years, depending upon the product. Burdick will repair or replace equipment
during the warranty period to ensure that the equipment will operate according
to its specifications. In addition to Burdick's service representatives,
authorized Burdick dealers maintain the equipment that they sell and provide
on-site field service whenever it is practical. Such dealers participate in
ongoing technical certification programs to ensure their technical expertise.
The Company's warranty costs are reflected in cost of sales in its Consolidated
Financial Statements.
 
Customers receive installation, technical training, clinical in-service and
documentation support appropriate for the product type. In the United States,
Spacelabs Medical's direct service force provides 24-hour-a-day, 7-day-a-week
technical phone support with its software support agreements and, when needed,
on-site repair. Internationally, Spacelabs Medical provides service either
through a direct organization or through distributors or third-party
organizations.
 
Spacelabs Medical believes that its customer service and support are an integral
part of its competitive strategy. Service capability, availability and
responsiveness play an important role in marketing and selling medical equipment
and systems, particularly as the technological complexity of the products
increases. Nevertheless, many hospitals use their own biomedical engineering
departments to service monitoring equipment after the warranty period expires.
Unlike some other areas of medical electronics, monitoring manufacturers cannot
depend on significant conversion to service contracts after the warranty period.
 
The Company has conducted a review of its current products and new products that
have been sold and shipped since December 31, 1992, to confirm whether the Year
2000 will cause products to fail or create erroneous results ("Year 2000
Compliance"). The Company believes that all products sold and shipped since
December 31, 1992, are either currently Year 2000 Compliant or will be capable
of attaining Year 2000 Compliance by means of product updates and/or upgrades
that the Company plans to complete and commercially offer to customers before
December 31, 1999. The Company has not assessed the potential Year 2000
Compliance expense and related potential effect on the Company's earnings, if
any, in the event such plans are not achieved. The Company has identified
certain older products sold or shipped before December 31, 1992, that will no
longer be supported by the Company by the Year 2000. These products will require
either a manual resetting of the date by the customer or an additional purchase
by the customer to become Year 2000 Compliant. The Company has not evaluated the
Year 2000 Compliance status of other products shipped before December 31, 1992.
The Company cannot determine whether or to what extent any of the products
shipped before December 31, 1992, will be in service as of the Year 2000.
 
COMPETITION
 
The worldwide markets for patient monitoring, diagnostic cardiology and CIS are
intensely competitive. Spacelabs Medical faces competition from many US and
international companies, some of which have far greater financial, marketing,
service, technical and research and development resources than those of the
Company. Within the critical care patient monitoring markets, Hewlett-Packard
Company's
 
                                        7
<PAGE>   10
 
Medical Products Group ("HP") is Spacelabs Medical's primary worldwide
competitor. Other critical care monitoring competitors include Marquette
Electronics, Inc. ("Marquette"), Nihon Kohden Corporation and Siemens AG.
Monitoring competitors in niche markets include Datascope Corporation, Datex
Medical Instrumentation, Inc., Medical Data Electronics and Protocol Systems,
Inc., plus many other small companies in countries outside the United States.
The primary competitors in the diagnostic cardiology markets are Marquette, HP,
Quinton, Zimed, Schiller, Mortara and a number of smaller niche companies.
Spacelabs Medical faces competition in CIS from HP and Marquette as well as from
a number of small niche vendors both in the United States and in other countries
and from hospital information system vendors such as HBO & Co., Shared Medical
Systems, Meditech and Cerner. Alliances and other cooperative arrangements among
competitors and/or other third parties are becoming more common. This may
increase competitive pressures.
 
Spacelabs Medical believes that the principal competitive factors in the market
for critical care patient monitoring, diagnostic cardiology and CIS products are
clinical utility, system technology, life-cycle cost-benefits and customer
support and service. Price has become an increasingly important competitive
factor, and at times the decisive factor, as hospitals come under increasing
pressure to forego added features in exchange for lower prices. Spacelabs
Medical also believes that the size of a particular manufacturer's installed
base is a competitive factor. In terms of acquisition costs, installation and
user training, hospitals make a long-term commitment when selecting a monitoring
or clinical information system. This factor tends to limit competition based on
changes in technology since hospitals cannot readily replace individual system
components with those from another manufacturer. Instead, hospitals will look to
their supplier for upgrades and, if not forthcoming, wait to replace the whole
system at the end of its useful life, typically seven or more years. Spacelabs
Medical believes that it competes favorably with respect to each of these
competitive factors.
 
PATENTS, TRADEMARKS AND LICENSES
 
Spacelabs Medical has obtained patents in the United States and other countries
on certain technology incorporated in its products and has applied for
additional patents that are presently pending. Spacelabs Medical has also sought
federal registration for certain trademarks under which products are sold. There
can be no assurance that any Spacelabs Medical patents are valid and
enforceable, that additional patents will be issued, that the Company's patents
will provide a competitive advantage or that trademark protection will be
granted and maintained. Spacelabs Medical believes, however, that no one of its
patents or trademarks is material to its products or business as currently
conducted.
 
Certain technology incorporated in Spacelabs Medical's products, including
software algorithms, is protected by copyright and trade secret laws. There can
be no assurance that such protection will prove adequate and that Spacelabs
Medical will have adequate remedies for unauthorized disclosure of its trade
secrets. Certain technology incorporated in Spacelabs Medical's products,
including software, is being used under licenses from third parties. The loss of
certain of such licenses could have a material adverse effect on the Company's
business.
 
The Company's competitors, like companies in many high-technology businesses,
routinely review the products of others for possible conflict with their own
patent rights. Although Spacelabs Medical has from time to time received notices
of claims from others alleging patent infringement, Spacelabs Medical believes
that there are no pending patent infringement claims that might have a material
effect on the business of the Company. There can be no assurance that Spacelabs
Medical or its licensers or suppliers will not be subject to additional claims
of patent infringement or that any claim will not require that Spacelabs Medical
pay substantial damages or delete certain features from its products or both.
Furthermore, it is possible that claims will be made by others that the Company
is infringing the trademark rights or copyrights of third parties, although the
Company is not currently aware of such claims.

GOVERNMENTAL REGULATION
 
The Company's medical products are subject to extensive regulation by numerous
governmental authorities, principally the US Food and Drug Administration (the
"FDA") and corresponding state and foreign agencies, and to various US and
foreign electrical safety standards. Spacelabs Medical's manufacturing facility
and the manufacture of its products are subject to FDA regulations regarding
registration of manufacturing facilities, compliance with the FDA's Quality
System Regulations and reporting of adverse events. Spacelabs Medical is also
subject to periodic on-site inspection for compliance with such regulations. The
FDA also has broad regulatory powers with respect to pre-clinical and clinical
testing of new medical products and the manufacturing, marketing and advertising
of medical products. Spacelabs Medical believes that there is a trend toward
increased regulation of device manufacturers by the FDA. For example, there has
been an increase in enforcement activity in manufacturing plant inspections and
related areas.
 
The FDA requires that all medical devices introduced to the market be preceded
by either a pre-market notification clearance order under section 510(k) of the
Food, Drug and Cosmetic Act or an approved pre-market approval application. A
510(k) pre-market notification clearance order indicates FDA agreement with an
applicant's determination that the product for which clearance has been sought
is substantially equivalent to another legally marketed medical device. An
approved pre-market 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 an average of between three to six months, but can take substantially
longer; the pre-market approval application review process typically lasts more
than a year. To date, all Spacelabs Medical products subject to such pre-market
regulation have required only 510(k) clearance.
 
Software used in medical devices, such as Spacelabs Medical's patient monitors,
is reviewed by the FDA in connection with the agency's clearance of the
pre-market notification for the related device. Computer health information
system or stand-alone software may also be subject to FDA regulations. A draft
policy issued by the FDA in 1989 has been the applicable guidance for the
regulation of computer products intended to affect the diagnosis or treatment of
patients. The 1989 draft policy exempts certain software from regulation on the
basis of "competent human intervention" occurring with the use of the software
before any impact on human health would occur. The FDA is considering a revised
policy, which is expected to eliminate this exemption and to base the level of
regulation on the level of risk imposed by the product. It is not clear what
impact such regulatory policies, if adopted, will have on clinical information
systems or other medical software offered by the Company.
 
Spacelabs Medical is also subject to regulation in the foreign countries in
which it markets its products. Certain foreign regulatory agencies establish
product standards different from those in the United States. Spacelabs Medical's
Redmond, Washington and Milton, Wisconsin operations are currently certified to
both the International Organization for Standardization's ("ISO") highest
standard, ISO 9001, and to the requirements of the European Medical Device
Directive 93/42 EEC ("MDD"). The MDD certification allows the Company to
self-certify that newly manufactured products conform to the European Community
quality standards, as shown by a "CE" mark placed on the product.
 
Spacelabs Medical believes that it is in material compliance with all applicable
federal, state and foreign regulations regarding the manufacture and sale of its
products. Such regulations and their enforcement are, however, constantly
undergoing change, and Spacelabs Medical cannot predict what effect, if any,
such change may have on its business. Approvals may be withdrawn for failure to
comply with regulatory standards or due to the occurrence of unforeseen
problems. Failure to comply with FDA regulations could result in warning
letters, product approval delays or other sanctions being imposed, including
restrictions on the marketing or the recall of the Company's products,
injunction or civil penalties. Delays in the receipt of or failure to receive
necessary regulatory approvals or the loss of existing approvals could have a
material adverse effect on Spacelabs Medical. Spacelabs Medical believes that
its products substantially comply with all applicable electrical safety and
environmental standards, such as those of Underwriters Laboratories and IEC 601.
 
                                        9
<PAGE>   12
 
Environmental. Spacelabs Medical is subject to federal, state and local
provisions regulating the discharge of materials into the environment or
otherwise for the protection of the environment. Spacelabs Medical believes it
is in material compliance with all such laws and regulations. Federal, state and
local governments are becoming increasingly sensitive to environmental issues,
and Spacelabs Medical cannot predict what impact future environmental
regulations may have on its operations.
 
CHANGES IN HEALTHCARE
 
Spacelabs Medical's critical care monitoring products are capital equipment
purchased primarily by hospitals. The decision to purchase monitoring equipment,
either to replace existing units or as part of a renovation or expansion, is
part of the hospital's general capital budgeting process. While some aspects of
monitoring may be billed separately, the costs of monitoring products are
normally recovered by the buyer as part of general charges for intensive care,
operating room and so forth. Reimbursement often covers only a portion of
charges. In general, purchases are driven by the need to provide adequate
monitoring to meet contemporary standards of care. Within this context,
monitoring products, along with other capital equipment, are purchased as a
hospital or foreign health authority can commit the funds. Any reimbursement
changes that tend to reduce a hospital's profitability or specifically reduce
capital reimbursement will tend to depress capital equipment spending. Hospital
managers also may delay purchases during periods of uncertainty about future
reimbursement and cash flow.
 
Spacelabs Medical's diagnostic cardiology products are used by healthcare
providers on both an in-and outpatient basis. Providers seek reimbursement from
third-party payors in the United States, principally Medicare, Medicaid and
private health insurance plans. Such reimbursement for diagnostic tests is
subject to the regulations and policies of government agencies and other
third-party payors. These third-party payors worldwide, including government
agencies, are under increasing pressure to contain medical costs.
 
Limits on reimbursement or other cost-containment measures imposed by
third-party payors or foreign health authorities may adversely affect the
financial condition and ability of hospitals and others to purchase products,
such as Spacelabs Medical's principal products, by reducing funds available for
capital expenditures or otherwise.
 
EMPLOYEES
 
As of February 6, 1998, Spacelabs Medical had approximately 1,600 full-time
employees. None of Spacelabs Medical's US employees are covered by collective
bargaining agreements, and the Company considers its employee relations to be
satisfactory worldwide.
 
FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES
 
Spacelabs Medical's products are marketed internationally through its
subsidiaries and independent distributors, with principal subsidiaries located
in Europe, Canada, Australia and Asia. The financial performance of the
Company's international operations for 1997, 1996 and 1995 are summarized in
Item 7, "Management's Discussion and Analysis of Financial Condition and Results
of Operations-Revenue" and Note 17 of "Notes to Consolidated Financial
Statements."
 
                               ITEM 2. PROPERTIES
 
Spacelabs Medical's corporate offices are at 15220 NE 40th Street, Redmond,
Washington 98052 in 400,300 square-feet of office and manufacturing space owned
by the Company. The Company's patient monitoring and CIS products are designed
and manufactured at this location. The Burdick product line is designed and
manufactured in a 108,000 square-foot leased facility in Milton, Wisconsin. The
fetal monitoring product line is manufactured in a 16,000 square-foot leased
facility in Hamden, Connecticut. The Company believes that its facilities are
adequate to meet its capacity requirements.

                           ITEM 3. LEGAL PROCEEDINGS
 
Spacelabs Medical is subject to various product liability and other proceedings
that arise in the ordinary course of its business. While the outcome of these
proceedings cannot be predicted with certainty, Spacelabs Medical believes that
none of such proceedings, individually or in the aggregate, will have a material
adverse effect on the Company's business, financial condition or financial
statements.
 
Spacelabs Medical maintains insurance coverage that it believes is appropriate
to its business and that is typical of similarly situated companies. There can
be no assurance that Spacelabs Medical'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.

      ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
OVERVIEW
 
Product and Market Expansion
 
During 1997 the Company expanded its product line and markets served for both
medical devices and information systems. Through the acquisition of Advanced
Medical Systems, Inc. ("AMS") it added fetal monitoring and a labor and delivery
information system. The Company added a line of diagnostic cardiology products
and a cardiology information management system through the acquisition of
Burdick, Inc. ("Burdick"). With the Burdick acquisition Spacelabs Medical's
sales and marketing presence was extended to the physician practice market. The
Company also introduced an emergency department information system. A number of
major new products were introduced for healthcare enterprise-wide application
including a clinical data repository and master patient index acquired in
connection with the acquisition of Ameritech Knowledge Data, Inc. ("AKD") and a
resource scheduling system through an investment in Tempus Software, Inc.
("Tempus").
 
US Medical Devices Market
 
The US healthcare delivery system continues to evolve in reaction to the
pressures of healthcare reform. Changes in the fundamental economics of
healthcare delivery, restructuring and consolidation among providers and a
corresponding increase in competitive pressures among vendors since 1992
contributed to declining US revenue through 1996. In reaction to this
restructuring and consolidation, customers' capital expenditures are being
reevaluated and reprioritized to respond to the needs of these newly formed
organizations. Though this pressure continues to hinder the vitality of the
market, the addition of new product lines and the Company's entry into new
markets during 1997 resulted in an overall growth of 5.5% over 1996. Though the
market for the medical devices sold by the Company is affected by advances in
technology, it remains primarily a replacement market driven by a provider's
decision to replace older or obsolete equipment. As a result, healthcare
providers have discretion in the timing of their equipment purchases and can
delay or postpone their purchases. In this market, competition for business is
intense, creating continued pricing pressure. These factors contribute to
uncertainty in revenue projections both on a quarterly and an annual basis.
 
International Medical Devices Market
 
International markets continue to be highly competitive and are characterized by
strong pricing pressures. Some areas of the world, such as selected Western
European countries, have implemented healthcare cost containment initiatives.
Other areas such as certain Latin American countries appear to be interested in
upgrading their healthcare systems. The Company's sales of its core products
continued to grow over the year, and when combined with the addition of the new
product lines and the Company's entry into new markets, the overall growth rate
was 10.0% over 1996. The combination of political, economic and healthcare
delivery policies and the Company's tactical sales approach can strongly
influence the market for capital equipment and the Company's performance in any
country or region in any given year. During 1997, international revenue was
negatively impacted by unfavorable foreign currency exchange rates during all
four quarters and by the economic and political situation in parts of Asia that
intensified during the last half of the year. The effects of worldwide political
and economic dynamics including currency exchange rates are not in the control
of the Company and, therefore, the impact on the Company's performance and
financial statements cannot be predicted.
 
Intesys Clinical Information Systems
 
The market for Clinical Information Systems ("CIS") remains in the early stages
of development. The impact of managed care and the subsequent restructuring that
has occurred among providers has delayed and postponed purchases of these
products as healthcare providers grapple with the problem of rethinking their
information systems strategies to support the business and patient management
 
                                       15
<PAGE>   18
 
needs of their organization in the environment of healthcare reform. Because the
market is emerging and the healthcare delivery system remains in a period of
transition it is difficult to predict the rate of growth of the market and,
therefore, the Company's ability to produce revenue from this product line.
Despite these difficulties, the Company did exceed its revenue objective in 1997
from the sales of Intesys products. The Company believes that changes in the
healthcare environment will create incentives to optimize process efficiencies,
control costs and increase the quality of patient care and, consequently, create
increased demand for these products. Automation of data collection, analysis and
distribution can play an important role in realizing such efficiencies and
increasing the quality of care that healthcare providers deliver.

- --------------------------------------------------------------------------------------------------
</TABLE>
 
Revenue for 1997 was $265.3 million, up from $248.0 million in 1996,
representing a 7.0% growth rate that approximates the contribution from the
consolidation of 18 weeks of diagnostic cardiology product line acquired with
Burdick. In 1996, revenue decreased 2.0% from $252.9 million in 1995.
 
The Company's 1997 US revenue increased by 5.5% from its 1996 level, which
followed a 6.7% decrease from 1995. In 1997, US revenue grew due to the addition
of the diagnostic cardiology product line and a strong sales performance by
Intesys healthcare information system products while US revenue from patient
monitoring products declined. The market for patient monitoring equipment
continues to be weak as a result of changes in the US healthcare delivery
system. At this time, management sees no identifiable factor in the environment
that would definitively signal an end to this trend.
 
International revenue, including export sales, grew by 10.0% to $90.7 million in
1997 from $82.5 million in 1996. 1996 revenue grew 9.1% over 1995. International
revenue was 34.2% of total revenue in 1997 compared with 33.3% in 1996 and 29.9%
in 1995. Growth in international revenue in 1997 was a result of continued
penetration of international markets and the addition of the diagnostic
cardiology line. Unfavorable foreign currency exchange rates and deteriorating
economic conditions in Asia negatively impacted growth of international revenue.
The unfavorable exchange rates in 1997 accounted for the loss of over 3
percentage points of growth as compared to 1996 in constant currency.
 
The Company continues to anticipate increasing quarterly revenue volatility as a
greater portion of its worldwide sales are generated from international and
Burdick operations and as the sales cycle becomes longer in the United States.
In international markets there is a higher degree of uncertainty in the timing
of orders resulting from the need for governmental approvals, more complex
financing arrangements and the instability in economic and political climates in
some parts of the world. With the changes in the US healthcare delivery system,
sales cycles have become longer and more complex resulting in less
predictability of order timing. Once the purchases are finalized, customers
require more rapid delivery of their orders. These dynamics combined with the
fact that Burdick products are shipped upon order to their distributors has
reduced the Company's overall time between order and shipment such that more
orders are being shipped in the same quarter in which they are ordered. As of
December 26, 1997, the Company had approximately $44.8 million of backlog orders
believed to be firm, compared to $53.8 million on December 27, 1996. Of the
$44.8 million it is estimated that approximately 15% will not ship within the
next 12 months. The decline in backlog is due in part to the reduced order to
delivery times described above. In addition, the unfavorable currency exchange
rate situation that was sustained over all four quarters of 1997 negatively
impacted the valuation of ending year backlog when compared to the previous
year. Backlog is subject to seasonal variation and historically has been greater
in the fourth fiscal quarter of the past three years.

</TABLE>
 
Gross margin as a percentage of revenue was 49.5% in 1997, compared to 50.4% in
1996 and 51.2% in 1995. The 1997 reduction in gross margin percent resulted in
part from the partial year consolidation of Burdick. Gross margins on Burdick
products are generally lower than the Company's historic margins because Burdick
products are sold primarily through distributors. Products are sold to
distributors at a lower price than to end users because distributors have
primary responsibility for the sales effort. In addition, worldwide pricing
pressures as well as foreign exchange rates continued to negatively influence
margins. Improved efficiency from the consolidation of manufacturing operations
to the facility in Redmond, Washington in 1996 and the incorporation of the
higher margin information systems sales partially offset the reduction of the
consolidated gross margin. Reduction of 1996 gross margin percent from 1995 was
caused principally by worldwide product pricing pressures attributable to
increased competition and changes in the healthcare environment. The Company
believes that pressure on gross margin from aggressive worldwide competitive
pricing will continue.

</TABLE>
 
Selling, general and administrative expenses increased 7.1% to $79.5 million in
1997 from $74.2 million in 1996. This increase resulted from the combined impact
of investment in worldwide sales and marketing relating to the strategic
acquisitions identified in the overview section above, as well as the ongoing
Intesys and international operations. As a percentage of revenue, these expenses
remained approximately the same at 30.0% in 1997 compared to 29.9% in 1996. In
1996, selling, general and administrative expenses of $74.2 million represented
an increase of 5.1% from $70.6 million in 1995. The increase was attributable to
international expansion and greater investment in Intesys sales and marketing
efforts.
 
Research and development costs in 1997 increased to $31.6 million from $28.3
million in 1996. The increase reflects the consolidation of Burdick and AKD
operations. In 1996, research and development costs declined $1.8 million from
1995 to $28.3 million as a result of efforts to contain overall costs. As a
percentage of revenue, research and development expenditures were 11.9% and
11.4% in 1997 and 1996, respectively, and were roughly consistent with historic
levels. As indicated in the past, as the Company continues to invest in clinical
information systems products, and transitions to become more of a software
development company, which typically invest greater amounts in research and
development, there may be some upward movement in these expenditures.
 
In 1997, the Company acquired in-process research and development in the amount
of $34.0 million, compared to $8.8 million in 1996. The 1997 expenditure
consisted of $21.4 million, $6.6 million and $6.0 million relating to the
acquisitions of Burdick, AMS and AKD, respectively. The 1996 expenditure
 
                                       17
<PAGE>   20
 
related to the acquisitions of JRS Clinical Technologies, Inc. and an investment
with DSA Systems, Inc. At the time of the acquisitions, the associated
in-process research and development had not demonstrated technological
feasibility and had no alternative future use. Therefore, these expenditures
were recognized as a period expense in accordance with Statement of Financial
Accounting Standards No. 2 and Financial Accounting Standards Board
Interpretation No. 4.
 
In 1997, the Company incurred a restructuring charge of $0.9 million to
eliminate certain duplicative activities associated with the Burdick
acquisition. In 1996 and 1995, the Company also incurred restructuring charges
of $7.1 million and $2.3 million, respectively, associated with the relocation
of its Chatsworth, California and Hillsboro, Oregon manufacturing operations to
its Redmond, Washington facility.

</TABLE>
 
Interest income in 1997 totaled $1.4 million compared to $2.4 million in 1996
and $3.8 million in 1995. The decrease in interest income for both years was
primarily a result of a reduction in cash available for investment.
 
Interest expense in 1997 increased to $2.3 million from $0.6 million in 1996 and
$0.5 million in 1995. The increase in interest expense in 1997 was principally
due to the additional interest on the new loan used to finance the acquisition
of Burdick and the capitalization of interest expense in 1996 of $0.4 million
related to the Company's Redmond, Washington facility.
 
Other expense included a loss from foreign currency fluctuations of $709,000 and
$236,000 in 1997 and 1996, respectively, and a gain of $59,000 in 1995. The
increase in foreign currency loss in 1997 was a result of the strengthening of
the US dollar against the currencies of the Company's foreign operations.

- --------------------------------------------------------------------------------
(1) The effective tax rates for both 1997 and 1996 were not meaningful due to
    the nondeductibility of the acquired in-process research and development
    charges, with the exception of those charges relating to the AKD
    acquisition. Excluding the impact of the in-process research and
    development, the effective tax rates for 1997, 1996 and 1995 were 36.7%,
    37.4% and 37.4%, respectively. This reflects the mix of federal, state and
    foreign tax rates.
 
(2) Per share data is based on the weighted average common shares and dilutive
    potential common shares outstanding for the Company.
 
During 1997, the Company reported a net loss of $20.4 million compared to net
income of $2.6 million in 1996. The loss in 1997 was a result of the significant
in-process research and development charges
                                       18
<PAGE>   21
 
associated with acquisitions. Excluding acquisition and restructuring charges
identified previously, net income was $11.9 million in 1997, $15.0 million in
1996, and $20.1 million in 1995, or $1.23, $1.46 and $1.86 per share in 1997,
1996 and 1995, respectively.
 
Net income exclusive of acquisition and restructuring expenses is not a
generally accepted accounting principle ("GAAP") measure, and investors should
not rely on it as a substitute for GAAP measures. Because acquisition and
restructuring expenses are fundamentally different in nature from ongoing
expenses from operations, management believes that a measure of net income
excluding these expenses is meaningful and useful to investors as it provides an
alternative basis with which management and investors can assess the
profitability of the Company's core operations.

Cash, Short Term Investments and Marketable Securities
 
The Company's combined cash and short-term investments were $12.9 million as of
December 26, 1997. The short-term investment portfolio is invested among
diversified security types and issuers, and it does not include any derivative
products.
 
The Company holds an investment in Physio Control International Corporation
common stock in the amount of 705,952 shares. Restrictions on the sale of these
shares lapsed in April 1997, and these shares are available to be converted to
cash if the Company so elects. Accordingly, this investment has been
reclassified from other long-term assets in 1996 to marketable equity securities
in 1997.
 
Working Capital
 
As a result of the Burdick acquisition, accounts receivable, inventories,
deferred income taxes and accrued liabilities significantly increased in 1997
compared to 1996. The increase to accrued liabilities includes $4.2 million
associated with plans to restructure certain activities of Burdick. The overall
impact of the acquisition on working capital was an increase of approximately
$5.4 million.
 
At December 26, 1997, the Company's working capital was $120.6 million as
compared to $131.7 million at December 27, 1996, reflecting the decline in cash
balances that related to the repurchase of treasury shares and various
acquisitions and investment activities.
 
Cash Provided (Used) by Operating Activities
 
During 1997, the Company used $12.8 million in cash from operations, including
cash paid to acquire in-process research and development of $28.0 million.
Excluding these expenditures, the Company generated $15.2 million in 1997
compared to $23.8 million in 1996. This decrease of $10.8 million resulted
primarily from decreases in accounts payable and accrued expenses, an increase
in accounts receivable and the decline in net income as identified above. The
decrease in accounts payable resulted primarily from changes in the timing of
payments for various liabilities incurred in 1997 and the reduction of accrued
expenses relating to the restructuring of manufacturing operations. The increase
in receivables is primarily attributable to the growth in international sales,
which is characterized by longer collection cycles.

Investing Activities
 
The Company invested $9.6 million in property, plant and equipment in 1997,
$18.3 million in 1996 and $17.2 million in 1995. Included in additions to
property, plant and equipment were construction costs of $8.1 million and $9.5
million in 1996 and 1995, respectively. The construction costs were incurred for
development of the manufacturing building in Redmond, Washington.
 
Other significant investment activities during 1997 included $60.2 million, of
which $28.0 million was charged to expense as acquired in-process research and
development, for the acquisitions of Burdick, AMS and AKD. In addition, $5.6
million was invested in Tempus and Bunnell.
 
Financing Activities
 
Significant uses of cash during 1997 included $10.7 million related to the
Company's stock repurchase programs authorized by the Board of Directors in
November 1995 and February 1997. Under the share repurchase program, 976,600
shares remained available for repurchase at December 26, 1997. Shares acquired
under the repurchase program are being used to service the Company's various
employee benefit plans and may be used for other purposes the Company deems
appropriate.
 
In 1997, in conjunction with the acquisition of Burdick, the Company entered
into a new long-term loan agreement with its primary lender. The new loan
commitment provides a maximum balance of $65.0 million. The outstanding balance
may vary in amount during the first three years over which time no repayments
are required. The balance outstanding at the end of three years will be
repayable on a straight-line basis over the next five years. As of December 26,
1997, the outstanding balance of this additional loan was $52.0 million. The
loan bears interest at margins over LIBOR. The Company continues to make monthly
payments of $62,500 on the preexisting long-term debt of $13.5 million, which is
due in total in December 2002. This debt also bears interest at a margin over
LIBOR. The portion of the outstanding balances on the instruments totaling $30.0
million and $13.5 million have been swapped for fixed rates of 6.66% and 7.07%,
respectively. In addition to these two loans, the Company has available $11.0
million of domestic lines of credit as well as several small credit lines to
meet the operating requirements of its international subsidiaries.
 
Future Cash and Liquidity
 
Management believes that existing cash and short-term investments, marketable
securities and cash flow from operations, together with available credit lines,
will continue to be sufficient to meet ongoing operating requirements as well as
the Company's investment in capital additions and research and development
activities. In connection with research and development, cash may be used from
time to time to acquire technology or to fund strategic ventures.
 
With respect to the Company's suppliers, service providers and internal systems
(e.g., manufacturing, administrative, management information systems and
financial) the Company has not yet fully assessed the potential Year 2000
Compliance expense and related potential effect on the Company's earnings, if
any. The Company has initiated a review of its major internal information
systems and has recently purchased information systems, in the normal course of
business, to replace two obsolete systems. The Company believes that the
majority of the implementation of these two systems will occur in 1998 and will
be completed in 1999.
 
FOREIGN CURRENCY
 
Substantially all of the revenue and operating expenses of the Company's foreign
subsidiaries are denominated in local currencies and translated into US dollars
at rates of exchange approximating those existing at the date of the
transactions. Foreign currency translation primarily impacts revenue and
operating expenses as a result of foreign exchange rate fluctuations.
 
The Company's foreign currency transaction risk is primarily limited to amounts
receivable from its foreign subsidiaries, which are denominated in local
currencies and totaled $8.0 million at December 26, 1997, $11.9 million at
December 27, 1996, and $8.5 million in December 29, 1995. The Company
                                       20
<PAGE>   23
 
recognizes foreign exchange gains and losses to the extent foreign exchange
rates fluctuate between the period the amounts receivable are first recorded and
when they are settled. To minimize foreign currency transaction risk, the
Company ensures that its foreign subsidiaries remit amounts to the US parent in
a timely manner. Foreign country short-term borrowing facilities are utilized
where necessary to ensure prompt payments. The Company does not currently
utilize foreign currency hedging contracts.

subject to uncertainties and risks including, but not limited to product and
service demand and acceptance, adverse economic conditions, adverse exchange
rate fluctuations and political risks, the impact of competition and pricing,

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Basis of Presentation
 
The consolidated financial statements include the accounts of Spacelabs Medical,
Inc. and its subsidiaries (the "Company"). Significant intercompany transactions
have been eliminated. Certain reclassifications have been made to prior period
financial statements to conform to the current presentation.
 
The Company's fiscal year is the 52- or 53-week period ending on the last Friday
in December. The fiscal years ended December 26, 1997, December 27, 1996 and
December 29, 1995 all consisted of 52 weeks.
 
Operations
 
The Company develops, manufactures, markets and services patient monitoring,
diagnostic cardiology and clinical information systems ("CIS") products for use
throughout the healthcare industry. The Company's principal products are used
for diagnosis, monitoring and information management across the healthcare
continuum. The Company also sells the disposable and replaceable supplies to
support these products.
 
Cash Equivalents, Short-Term Investments and Marketable Securities
 
All liquid investments with a maturity of three months or less at the date of
purchase are considered to be cash equivalents.
 
Included in short-term investments and other assets are investment securities.
The Company's marketable equity securities are classified as available-for-sale
and carried at market value, with unrealized gains and losses excluded from the
consolidated statements of income and reported in a separate component of
shareholders' equity. Gross realized gains and losses on the sales of investment
securities are determined on the specific identification method and included in
other income (expense).
 
Inventories
 
Inventories are valued at the lower of cost, as determined by the first-in,
first-out method, or market.
 
Property, Plant and Equipment
 
Property, plant and equipment are stated at cost. Significant additions and
improvements are capitalized. Maintenance and repairs are expensed as incurred.
When properties are retired or otherwise disposed of, gains and losses are
reflected in the Consolidated Statements of Operation. Depreciation is provided

Leasehold improvements are amortized over the shorter of their useful lives or
the term of the lease. The Company continually evaluates the estimated useful
lives of its property, plant and equipment and from time to time makes changes
to these estimates based on experience and trends in utility. During 1997, the
Company changed the estimated useful lives of certain machinery and equipment
that resulted in a $750 decrease in depreciation expense from that which would
have been recorded under the old useful lives.

Intangible Assets
 
Intangible assets, primarily representing cost in excess of net assets of
businesses acquired, are amortized using the straight-line method over 5 to 40
years.
 
Foreign Currency
 
Revenue and expenses of the Company's international operations denominated in
foreign currencies are translated to US 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 charged or credited to shareholders' equity.
Gains and losses on foreign currency transactions are included in other income
(expense).
 
Revenue Recognition
 
Revenue is generally recognized upon shipment of products and delivery of
services to customers.
 
Deferred revenue consists of deposits received from customers and unamortized
service contract revenue. The revenue derived from these contracts is initially
deferred and subsequently recognized on the straight-line method over the lives
of the contracts.
 
Income Taxes
 
Deferred tax assets and liabilities have been established for the expected
future tax consequences of events that have been recognized in the Company's
Consolidated Financial Statements and tax returns. These deferred tax assets and
liabilities are determined based on the differences between the financial
statement carrying amounts and tax bases of assets and liabilities using
currently enacted tax rates that are expected to be in effect during the years
in which the differences are anticipated to reverse.
 
Product Warranties
 
The Company provides currently for the estimated cost to repair or replace
products sold under warranties. Such warranties for hospital equipment and CIS
are generally for the earlier of 14 months from the date of original delivery or
12 months from first on-line operation. Primary care products are warranted,
inclusive of software, for all parts and labor during the warranty term, which
ranges from one to five years.
 
Accounting Estimates
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reported period. Actual
results may differ from these estimates.
 
Concentrations of Credit Risk
 
Financial instruments that potentially subject the Company to concentrations of
credit risk consist principally of cash equivalents and short-term investments
and trade accounts receivable. The Company's cash equivalents and short-term
investments are diversified among security types,

                 (dollars in thousands, except per share data)
 
institutional issuers and industry groups. Trade accounts receivable reflect a
broad customer base both nationally and internationally.
 
As the Company continues to expand internationally, a greater portion of its
receivables are with customers located in foreign countries. While the Company
attempts to secure payments with banking instruments such as letters of credit,
some export sales are transacted with credit terms, and therefore collection of
receivables is affected by local economic conditions. Also, with respect to
foreign export sales, collection may be more difficult in the event of default.
 
The Company frequently contracts for the sale of its products with hospital
buying groups, proprietary hospital chains and US government agencies. These
contracts can generate significant revenues and the Company believes the loss of
a major contract could have an adverse effect on its operations.
 
The Company depends on single-source vendors for certain integral component
parts. While any of these vendors could be replaced over time, abrupt disruption
in the supply of a single-source part could have an adverse effect on the
Company's manufacture of the products of which such items are a component. In
addition, component parts of certain of the Company's products are manufactured
in Asian countries that periodically experience political and economic
difficulties.
 
Income Per Share
 
In accordance with Statement of Financial Accounting Standards ("SFAS") No. 128,
Earnings Per Share, the Company has reported both basic and diluted net income
(loss) per common share for each period presented. Basic income per share is
computed on the basis of the weighted-average number of shares outstanding for
the year. Diluted income per share is computed on the basis of the
weighted-average number of common shares plus dilutive potential common shares
outstanding. Dilutive potential common shares are calculated under the treasury
stock method and consist of unexercised employee stock options and unvested
restricted shares outstanding.
 
Stock-Based Compensation
 
SFAS No. 123, Accounting for Stock-Based Compensation, permits a company to
choose either a new fair-value-based method or the APB Opinion 25
intrinsic-value-based method of accounting for stock-based compensation
arrangements. SFAS No. 123 requires pro forma disclosures of net income and
earnings per share computed as if the fair-value-based method had been applied
in financial statements of companies that continue to account for such
arrangements under APB Opinion 25. The Company has elected to continue to record
stock-based compensation using the APB Opinion 25 intrinsic-value-based method.
 
Impairment of Long-Lived Assets
 
The Company periodically assesses the recoverability of long-lived assets
including property, plant and equipment, cost in excess of net assets of
business acquired and other intangible assets. Recoverability of assets to be
held and used is measured by a comparison of the carrying amount of an asset to
future net cash flows expected to be generated by the asset. If such assets are
considered to be impaired, the impairment to be recognized is measured at the
amount by which the carrying amount of the assets exceeds the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or the fair value less costs to sell.

agreements at December 26, 1997, or December 27, 1996. Restrictive terms of
these lines of credit require, among other things, that the Company maintain
specified financial ratios. The Company was in compliance with these covenants
at December 26, 1997.
 
The Company has available for working capital purposes unsecured bank lines of
credit maintained by various foreign subsidiaries. The Company had drawn $1,314

remaining principal amount of $9,750 is due.
 
During the third quarter of 1997, in conjunction with the acquisition of Burdick
Inc. ("Burdick"), the Company entered into an additional long-term agreement
with its primary lender. The new loan commitment consists of $30,000 in bank
debt and up to $35,000 in revolving debt. Amounts remaining

unpaid on both the $30,000 debt and the $35,000 debt after the end of three
years will be repayable on a straight-line basis over the succeeding five years.
As of December 26, 1997, there is $22,000 outstanding of the $35,000 revolving
debt. Interest on the $30,000 debt is payable at a margin over the three-month
LIBOR (6.18% at December 26, 1997). The revolving bank debt bears interest at
the primary lender's cost of funds (5.94% at December 26, 1997).
 
Restrictive terms of the bank debt agreements require that the Company maintain
specified financial ratios and comply with certain other loan covenants. The
Company was in compliance with these covenants at December 26, 1997.
 
To manage interest costs and risks associated with interest rate fluctuations on
its long-term debt, the Company has entered into two interest rate swap
agreements with its primary lender. The first of such agreements, in the
notional amount equivalent to the indebtedness, effectively exchanges the
variable rate on the Company's 1995 long-term debt for a fixed rate of 6.66%.
The swap agreement expires in 2002. The second agreement, in the notional amount
equivalent to the principal balance of the $30,000 debt, effectively exchanges
the variable rate on the Company's 1997 long-term debt for a fixed rate of
7.065%. This swap agreement expires in 2005. The differential to be paid or
received under either of the arrangements is accrued as interest rates change
and is recognized as an increase or reduction to interest expense over the life
of the agreements. The counterparty under the swap arrangements is a major
financial institution and credit loss from counterparty nonperformance is not
anticipated.
 
In the third quarter of 1997, in conjunction with the acquisition of Ameritech
Knowledge Data, Inc. ("AKD"), the Company issued an unsecured promissory note to
pay Ameritech Health Connections, Inc. $7,138 at an interest rate of 7.5%,
payable quarterly. The note is repayable in six equal quarterly installments
from August 1997 through November 1998.
 
Scheduled maturities of long-term debt at December 26, 1997, are as follows:

The provision for income taxes differs from the amount of income tax determined
by applying the applicable US statutory federal income tax rate to pretax income
(loss), as a result of the following:

The net changes in the valuation allowance for deferred tax assets was a
decrease of $168 in 1997, an increase of $264 in 1996 and a decrease of $291 in
1995. These changes primarily relate to net operating loss carryforwards
generated or utilized by foreign operations.
 
At December 26, 1997, the Company had net operating loss carryforwards for US
federal tax purposes of approximately $2,417, resulting from a 1990 acquisition
and the acquisition of AMS. These net operating loss carryforwards expire
between 2004 and 2011.
 
At December 26, 1997, the Company also had international net operating loss
carryforwards for tax purposes of approximately $350, which contain carryforward
periods ranging from five years to unlimited years.
 
11. SHAREHOLDERS' EQUITY
 
Purchase of Treasury Shares
 
The Board of Directors authorized the repurchase of up to three million shares
of the Company's common stock, subject to certain limitations and conditions. In
addition, the Board of Directors has also approved odd-lot repurchase programs.
The Company repurchased 491,200, 796,200 and 100,000 shares in 1997, 1996 and
1995, respectively. As of December 26, 1997, the Company had purchased 2,129,954
shares at a total cost of $48,099. The shares are used to service the Company's
employee benefit plans and may be used for other purposes the Company deems
appropriate.

</TABLE>
 
Stock options and unvested restricted stock outstanding were not included in the
computation of diluted loss per share for 1997, because the representative share
increments would be antidilutive. Stock options remaining outstanding totaled
2,430,020 as of December 26, 1997, with a weighted average exercise price of
$22.19 and a weighted average remaining contractual life of 7.2 years. Stock
options outstanding for which the options' exercise price was greater than the
average market price of common shares were not included in the computation of
diluted net income (loss) per share in 1997, 1996 and 1995.
 
13. EMPLOYEE BENEFIT PLANS
 
Pension Plans
 
Except for employees of the Company's Burdick operations, substantially all
employees of the Company's US operations are covered under noncontributory
defined benefit pension plans. The benefits under these plans are based on the
employees' years of service and highest consecutive five-year average
compensation.
 
Net pension cost comprises the following:

</TABLE>

The weighted average discount rate used in determining the actuarial present
value of the projected benefit obligation was 7.25% for 1997 and 7.75% for 1996.
The assumed rate of increase in future compensation levels was 5.5% for each of
1997, 1996 and 1995, and the expected long-term rate of return on plan assets
was 9.0% for each of 1997, 1996 and 1995.

Post-retirement Benefit Plan, Burdick Acquisition

The Company also provides unfunded healthcare and life insurance benefits to
certain retirees of its Burdick subsidiary. Current employees of the Company are
not entitled to these benefits upon retirement.

Net post-retirement benefit cost since acquisition of Burdick consisted solely
of interest costs of $49. The accrued post-retirement benefit cost at December
26, 1997, comprises solely of the accumulated post-retirement benefit obligation
of $2,096.

The weighted average discount rate used in determining the actuarial present
value of the accumulated post-retirement benefit obligation was 7.25%. For 1997,
future benefit costs were estimated assuming medical costs would increase at a
10% annual rate, with the rate decreasing for seven years after 1997 until it
reaches 5%, and remain constant thereafter.

A 1% increase in the assumed healthcare cost trend rate would have an
insignificant impact on the accumulated post-retirement benefit obligation and
the annual benefit cost.

ISSOP 401(k) Plan

Spacelabs Medical ISSOP 401(k) Plan: The Company maintains an Incentive Savings
and Stock Ownership Plan for the majority of its full-time US resident employees
with at least one year of service. Under the plan, participating employees may

per year over a five-year period. Company contributions to the savings plan were
$706, $672, and $844 in 1997, 1996 and 1995, respectively.

Burdick, Inc. 401(k) Savings Plan: Full-time employees of the Company's Burdick
operations are not eligible to participate in the Spacelabs Medical ISSOP 401(k)
Plan; however, they are entitled to participate in a separate 401(k) savings

contributed by a participant provided the participant contribution does not
exceed 4% of the employee's earnings. Company contributions under the Burdick,

Stock Option Plans
 
At December 26, 1997, the Company has five stock-based compensation plans, which
are described below. The Company applies APB Opinion No. 25 and related
interpretations in accounting for its plans, under which no compensation cost
has been recognized for its stock option awards. Had compensation cost for the
Company's stock option awards been determined consistent with Statement of
Financial Accounting Standards No. 123, the Company's net income (loss) and net
income (loss) per share would have been reduced to the pro forma amounts
indicated below:

In deriving the above, the fair value of each option grant is estimated on the
date of grant using the Black-Scholes option-pricing model with the following
weighted average assumptions used for grants in 1997, 1996 and 1995
respectively: dividend yield of 0% for each year; expected volatility of 34%,
36% and 39%; risk-free interest rates of 6.3%, 5.7% and 7.1%; and expected lives
of 4.4 years, 4.1 years and 4.1 years for the Nonofficer Employee Plan options,
5.2 years, 4.8 years and 4.8 years for the 1992 Plan options, and 4.3 years, 4.2
years and 4.2 years for the Director Plan options.

PERFORMANCE UNIT PLAN (THE "1992 PLAN"):
 
Under the 1992 Plan, as amended and restated, for each calendar year from and
including 1995 through May 10, 2000, the number of shares authorized for
issuance is equal to an amount of up to 2% of the adjusted average common shares
outstanding of the Company used to calculate diluted earnings per share as
reported in the annual report to stockholders for the preceding year. In
addition, any shares authorized for issuance under the formula in any previous
year (1995 or later) but not actually issued under the 1992 Plan will be added
to the number of shares that become authorized for issuance in any current year.
Within the limit established by the formula, over the term of the 1992 Plan, not
more than an aggregate of 500,000 shares of common stock may be issued pursuant
to the exercise of incentive stock options under the 1992 Plan and not more than
an aggregate of 500,000 shares may be issued pursuant to grants or awards of
restricted stock, stock grants or performance units under the 1992 Plan.
 
At December 26, 1997, 88,908 shares were available for future grant under the
1992 Plan. In accordance with the replenishment formula, total shares available
for future grant increased to 280,208 at January 1, 1998. On January 1, 1998,
372,796 shares were available for issuance on exercise of incentive stock
options over the remaining term of the 1992 Plan, and 477,800 shares were
available

Each in-process research and development project identified at the time of the
acquisition was evaluated as to its state of completion and its technological
feasibility in accordance with Statement of Financial Accounting Standards No. 2
and Financial Accounting Standards Board Interpretation No. 4. Since the
acquired in-process research and development had not demonstrated technological
feasibility and had no alternative future use, it was recognized as a period
expense.
 
20. BUSINESS COMBINATIONS
 
On August 21, 1997, the Company acquired for cash all the outstanding shares of
common stock of Burdick. Burdick develops and manufactures diagnostic cardiology
equipment in Milton, Wisconsin. The Burdick acquisition was recorded under the
purchase method of accounting. Accordingly, the results of Burdick's operations
from August 21, 1997, are included in the Company's consolidated financial
statements. The purchase price of $51,234, including acquisition costs, has been
allocated to assets acquired and liabilities assumed based on their fair market
value at the date of acquisition, as well as to acquired in-process research and
development. The excess of the purchase price over the fair market value of the
net identifiable tangible assets has been recorded as cost in excess of net
assets acquired of $19,110 and other intangible assets of $6,698. These amounts
are being amortized on a straight-line basis over 20 years.
 
In connection with the acquisition, the Company has initiated a plan to
integrate the Burdick operations into the Company's existing operations. The
integration plan will eliminate duplicate technologies and production capacity,
relocate the Burdick operation to a smaller facility in the same regional area
and

operations. Estimated costs associated with this plan as of the acquisition date

A decrease in the original accrual estimate will result in a decrease in the
cost in excess of net assets acquired. An increase in the original accrual
estimate will be recorded as additional cost in excess of net assets acquired if
within one year from date of acquisition, or if after that date, as a charge to
operations.
 
Since acquisition, no material costs have been charged against this accrued
liability.
 
The following unaudited pro forma financial information presents the combined
results of operations of the Company and Burdick as if the acquisition had
occurred as of the beginning of 1997 and 1996 after giving effect to certain
adjustments, including amortization of cost in excess of net assets acquired,
increased interest expense on debt related to the acquisition, in-process
research and development and restructuring charges, and related income tax
effects. The pro forma financial information does not necessarily reflect the
results of operations that would have occurred had the Company and Burdick
operated as a single entity during such periods.

The Company also acquired Advanced Medical Systems, Inc. ("AMS") and AKD in the
first and third quarters of 1997, respectively. The total purchase price of
these two acquisitions, including acquisition costs, was $14,991 and the
purchase method of accounting was used. To determine fair market value and
acquired in-process research and development in these two acquisitions the basis
of allocation was the same as that used in the Burdick purchase. Pro forma
financial information has not been included for these two acquisitions, because,
excluding the impact of in-process research and development, they are not
material to the Company's operations.

22. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
The following fair value amounts have been determined using available market
information and appropriate valuation methodologies. However, considerable
judgment is required in interpreting market data to develop the estimates of
fair value. Accordingly, the estimates presented herein are not necessarily
indicative of the amounts that the Company could realize in a current market
exchange. The use of different market assumptions and/or estimation
methodologies may have a material effect on the estimated fair value amounts
provided below.

values.

Marketable Equity Securities: The fair value of these securities is based on
quoted market prices. As of December 27, 1996 the Company's investment in Physio
Control International Corporation was restricted. The value of the restricted
stock was estimated based on the existing market price discounted for market
risk factors and the time value of money.
 
Long-Term Investments: The fair value of other investments was estimated based
on existing market conditions.
 
Investments for which it was not practicable to estimate the fair value consist
primarily of the stock of a nonpublic company.
 
Long-Term Debt: The carrying amount of the Company's long-term debt approximates
its fair value as interest rates on the underlying debt instruments are variable
in nature and tied to prevailing market rates.
 
Interest Rate Swap Agreement: In the third quarter of 1997, the Company entered
into a new interest rate swap agreement related to the Burdick acquisition. The
fair value of this agreement, as well as the fair value of the previously
existing swap arrangement, was based upon an estimate of the amount at which the
agreements could be settled between the counterparties.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
Spacelabs Medical, Inc.
 
We have audited the consolidated financial statements of Spacelabs Medical, Inc.
and subsidiaries as listed in the accompanying index. In connection with our
audits of the consolidated financial statements, we also have audited the
financial statement schedule as listed in the accompanying index. These
consolidated financial statements and the financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and the financial statement
schedule based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Spacelabs Medical,
Inc. and subsidiaries as of December 26, 1997 and December 27, 1996, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 26, 1997, in conformity with generally accepted
accounting principles. Also in our opinion, the related financial statement
schedule, when considered in relation to the basic consolidated financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.

                  (2)   SELECTION OF ALTERNATIVE RATES. Subsections 2.8(c)(1),
(2) and (4) are hereby amended and restated as follows:

      Applicable IBOR Rate, Overnight Rate, or the Quoted Rate) or two (2)
      London Business Days' prior notice (in the case of a selection of an
      Applicable LIBOR Rate) elect to have interest accrue on any Loan or any
      portion thereof at an Applicable LIBOR Rate, and in the case of any
      Burdick Loan or any Revolving Loan at the Overnight Rate or the Applicable
      IBOR Rate, and in the case of the Term Loan at the Quoted Rate, for an
      Applicable Interest Period. Such notice (herein, an "Interest Rate
      Notice") shall be deemed delivered on receipt by Agent except that any

      any Business Day, shall be deemed to be received on the immediately
      succeeding Business Day. An Interest Rate Notice may be given in writing

<PAGE>   6
      selects. Any such Interest Rate Notice shall be irrevocable and shall
      constitute a representation and warranty by Borrower that as of the date
      of such Interest Rate Notice no Event of Default or Default has occurred
      and is continuing. On receipt of such Interest Rate Notice, Agent shall
      promptly notify each Lender by telephone (confirmed promptly by telex or
      facsimile transmission) of the information set forth in the Interest Rate
      Notice.

                        (2)   Borrower's right to select an Overnight Rate,
      Applicable IBOR Rate or Applicable LIBOR Rate to apply to a Loan or any
      portion thereof shall be subject to the following conditions: (i) neither

      be selected for any Loan or portion thereof which is already accruing
      interest at an Overnight Rate, an Applicable IBOR Rate or an Applicable
      LIBOR Rate unless such selection is only to become effective at the
      maturity of the Applicable Interest Period then in effect; (ii) Agent
      shall not have given notice pursuant to Section 2.8(e) that the LIBOR Rate
      selected by Borrower is not available; (iii) in the case of a Burdick
      Loan, the aggregate of all Burdick Loans or portions thereof accruing
      interest at a particular Overnight Rate, IBOR Rate or LIBOR Rate for the
      same Applicable Interest Period, and in the case of a Revolving Loan, the
      aggregate of all Revolving Loans or portions thereof accruing interest at
      a particular Overnight Rate, IBOR Rate or LIBOR Rate for the same
      Applicable Interest Period, shall, in each case, be an integral multiple
      of Five Thousand Dollars ($5,000); (iv) no Default or Event of Default
      shall have occurred and be continuing; and (v) if Borrower elects to have
      some portion (but less than all) of the Burdick Loans or the Revolving
      Loans accrue interest at a designated Overnight Rate, IBOR Rate or LIBOR
      Rate, Borrower shall select a portion of each Lender's Burdick Loans or
      Revolving Loans, as the case may be, to accrue interest at such rate in
      proportion to their respective Burdick Percentage Interests or Revolving
      Percentage Interests, as the case may be.

                        (4)   In the absence of an effective request for the
      application of an Overnight Rate, an Applicable IBOR Rate, an Applicable
      LIBOR Rate or Quoted Rate, the Loans or remaining portions thereof shall
      accrue interest at the Base Rate.


                                       6
<PAGE>   7
                  (3)   UNAVAILABLE IBOR OR LIBOR RATES. Subsection 2.8(e) is
hereby amended and restated as follows:

                  (e)   UNAVAILABLE IBOR OR LIBOR RATES. If, for any reason, any
      Lender determines that a fair and adequate means does not exist for
      establishing a particular IBOR Rate or LIBOR Rate or that the making or
      continuation of any IBOR Rate Loan or LIBOR Rate Loan by such Lender has
      become unlawful, then such Lender may give notice of that fact to Agent
      and Borrower and such determination shall become conclusive and binding
      absent manifest error. After such notice has been given and until Lender
      notifies Agent and Borrower that the circumstances giving rise to such
      notice no longer exist, such IBOR Rate or LIBOR Rate, as the case may be,
      shall no longer be available in respect of Loans. Any subsequent request
      by Borrower to have interest accrue at such an IBOR Rate or LIBOR Rate
      shall be deemed to be a request for interest to accrue at the Base Rate.
      If such Lender shall thereafter determine to permit borrowing at such
      rate, such Lender shall notify Agent and Borrower in writing of that fact,
      and Borrower shall then once again become entitled to request that such
      IBOR Rate or LIBOR Rate apply to the Loans in accordance with Section
      2.8(c).

                  (4)   SELECTION OF ALTERNATIVE RATES. The first paragraph of
Subsection 2.8(f) is hereby amended and restated as follows:

      In the event that after the date hereof any change occurs in any
      applicable law, regulation, treaty or directive or interpretation thereof
      by any Government Authority charged with the administration or
      interpretation thereof, or any condition is imposed by any Government
      Authority after the date hereof or any change occurs in any condition
      imposed by any Government Authority on or prior to the date hereof which:

                        (1)   subjects any Lender to any Tax, or changes the
      basis of taxation of any payments to any Lender on account of principal of
      or interest on any IBOR Rate Loan, LIBOR Rate Loan, Quoted Rate Loan, the
      Notes (to the extent such Note evidences an IBOR Rate Loan, a LIBOR Rate
      Loan or a Quoted Rate Loan) or fees in respect of such Lender's obligation
      to make an IBOR Rate Loan, a LIBOR Rate Loan, a Quoted Rate Loan or other
      amounts payable with respect to any IBOR Rate Loan, LIBOR Rate Loan or
      Quoted Rate Loan (other than a


                                       7
<PAGE>   8
      change in the rate of tax based solely on the overall net or gross income
      of such Lender); or

                        (2)   imposes, modifies, or determines applicable any
      reserve, deposit or similar requirements against any assets held by,
      deposits with or for the account of, or loans or commitments by, any
      office of any Lender in connection with an IBOR Rate Loan, a LIBOR Rate
      Loan or a Quoted Rate Loan to the extent the amount of which is in excess
      of, or was not applicable at the time of computation of, the amounts
      provided for in the definition of Applicable IBOR Rate, Applicable LIBOR
      Rate or Quoted Rate; or

                        (3)   affects the amount of capital required or expected
      to be maintained by banks generally or corporations controlling banks and
      any Lender determines the amount by which such Lender or any corporation
      controlling such Lender is required or expected to maintain or increase
      its capital is increased by, or based upon, the existence of this
      Agreement or of any Loan hereunder; or

                        (4)   imposes upon any Lender any other condition with
      respect to any IBOR Rate Loan, LIBOR Rate Loan or Quoted Rate Loan or its
      obligation to make an IBOR Rate Loan, a LIBOR Rate Loan or a Quoted Rate
      Loan; which, as a result thereof,

      (a) increases the cost to any Lender of making or maintaining its Loans
      hereunder, or (b) reduces the net amount of any payment received by any
      Lender in respect of its IBOR Rate Loans, LIBOR Rate Loans or Quoted Rate
      Loans (whether of principal, interest, or otherwise), or (c) requires any
      Lender to make any payment on or calculated by reference to the gross
      amount of any sum received by it in respect of its IBOR Rate Loans, LIBOR
      Rate Loans or Quoted Rate Loans, in each case by an amount which such
      Lender in its sole judgment deems material, then in any such case Borrower
      shall pay to such Lender on demand such amount or amounts as will
      compensate such Lender for any increased cost, deduction or payment
      actually incurred or made by such Lender. The demand for payment by such
      Lender shall be delivered to Borrower and Agent and shall state the
      subjection or change which occurred or the reserve or deposit requirements
      or other conditions which have been imposed upon such Lender or the
      request, direction or requirement with which it has complied, together
      with the date thereof, the amount of such cost, reduction or payment and
      the manner in which such


                                       8
<PAGE>   9
      amount has been calculated. The statement of any Lender as to the
      additional amounts payable pursuant to this Section 2.8(f) shall be
      binding on Borrower in the absence of manifest error.

            (c)   AMENDMENT TO SECTION 2.9. Section 2.9 is hereby amended and
restated as follows:

                  SECTION 2.9 PREPAYMENTS. Base Rate Loans may be repaid at any
      time without a prepayment fee. Overnight Rate Loans, IBOR Rate Loans,
      LIBOR Rate Loans and any Quoted Rate Loan may be repaid at the end of an
      Applicable Interest Period without a prepayment fee. Quoted Rate Loans may
      not be voluntarily repaid prior to the end of the Applicable Interest
      Period. If an Overnight Rate Loan, an IBOR Rate Loan, a LIBOR Rate Loan or
      a Quoted Rate Loan is repaid prior to the end of the Applicable Interest
      Period, a prepayment fee computed in the manner set out in Schedule 1
      shall be assessed and paid at the time of such early repayment. Such fee
      shall apply in all circumstances where an Overnight Rate Loan, an IBOR
      Rate Loan, a LIBOR Rate Loan or a Quoted Rate Loan is paid prior to the
      end of the Applicable Interest Period, regardless of whether such payment
      is voluntary, mandatory or the result of Agent's or Lenders' collection
      efforts.

            (d)   AMENDMENT TO SECTION 2.10. The first sentence of subsection
Section 2.10(b) is hereby amended and restated as follows:

      Each Lender is hereby authorized to record the date and amount of the
      Loans it makes, the Base Rate, the Overnight Rate, the Applicable IBOR
      Rate, Applicable LIBOR Rate or Quoted Rate, as applicable, and the date
      and amount of each payment of principal and interest thereon on a schedule
      annexed to or kept in respect of any Note.

            (e)   AMENDMENTS TO SCHEDULE 1: Schedule 1 is hereby amended and
restated as set forth in Schedule 1 attached hereto.

representation or warranty made hereunder shall prove to have been incorrect in
any material respect when made.

      5.    NO FURTHER AMENDMENT. Except as expressly modified by this

                                   SCHEDULE 1

                                 Prepayment Fees

      The amount of the fee to be paid pursuant to Section 2.7 shall depend on
the following:

      (1)   The amount by which interest rates have changed between the
            Reference Date and the Prepayment Date. As used herein, "Reference
            Date" shall mean the first day of an Applicable Interest Period. As
            used herein, "Prepayment Date" shall mean the date Borrower either
            voluntarily or involuntarily prepays an Overnight Loan, an IBOR Rate
            Loan, a LIBOR Rate Loan or a Quoted Rate Loan. Certain U.S. Treasury
            rates are used as a benchmark to measure changes in interest rate
            levels.

            (a)   A "reference rate" equal to the average interest rate yield at
                  the Reference Date for U.S. Government Securities having
                  maturities equivalent to that of the applicable Overnight Rate
                  Loan, IBOR Rate Loan, LIBOR Rate Loan or Quoted Rate Loan will
                  be determined in the manner described below for determining
                  applicable rates but will be established as of the Reference
                  Date for the Applicable Interest Period. This rate represents
                  interest rate levels at the time an Overnight Rate Loan, an
                  IBOR Rate Loan, a LIBOR Rate Loan or a Quoted Rate Loan is
                  made or its interest rate fixed.

            (b)   An "applicable rate," determined as described below,
                  represents interest rate levels as of the Prepayment Date.

      (2)   The amount of principal prepaid.

      (3)   A payment fee factor (see "payment fee factor schedule" below). This
            factor represents the economic loss to a Lender resulting from a one
            dollar payment if rates were to drop by one percent from the time
            the rate was fixed.

<PAGE>   15
                          CALCULATION OF PREPAYMENT FEE

      If the reference rate is lower than or equal to the applicable rate, there
is no prepayment fee.

      If the applicable rate is lower than the reference rate, the prepayment
fee shall be equal to the difference between the reference rate and the
applicable rate (expressed as a decimal), multiplied by the appropriate factor
from the prepayment fee factor schedule, multiplied by the principal amount of
the LIBOR Rate Loan or Quoted Rate Loan which is prepaid.

      Example:

      A LIBOR Rate Loan with principal of $850,000 is fully prepaid with 4
      months remaining prior to the end of the Applicable Interest Period. A
      reference rate of 10% was assigned to the LIBOR Rate Loan when the rate
      was fixed. The applicable rate (as determined by current 4-month U.S.
      Treasury rates) is 8.5%. Rates are therefore judged to have dropped by
      1.5% since the rate was fixed, and a prepayment fee applies.

      A prepayment fee factor of .37 is determined from the tables below, and
      the prepayment fee is computed as follows:

Prepayment Fee = (.10-.085) x (.37) x ($850,000) = $4,717.50

                                APPLICABLE RATES

      The applicable rate is equal to the average interest rate yield at the
time of prepayment for U.S. Government Securities having maturities equivalent
to the remaining portion of the Applicable Interest Period.

      The applicable rate shall be determined from the Federal Reserve
Statistical Release (Publication H.15(519)) in the "This Week" (most recent
week) column under the heading U.S. Government Securities - Treasury Bills -
Secondary Market, interpolated to the nearest month.

      Rates listed in the Federal Reserve Statistical Release for maturities of
less than one year are on a discount rate basis, and these rates shall be
converted to a coupon equivalent basis, based upon a 360-day year. The
Statistical Release published on Monday shall be used for calculation of
prepayment fees payable on the following Tuesday through the following Monday,
with appropriate adjustment if the day of publication changes.

such termination

            (b)   Termination Other Than for Cause. The Company shall have the

other than for cause, the Executive shall be entitled to receive: (1) his base
salary and employee benefits as accrued through the effective date of such
termination and (2) an amount equal to the Executive's then current base salary

be entitled to receive any compensation hereunder other than his base salary and
employee benefits as accrued through the effective date of such termination.

            (d)   Death or Disability. The Executive's employment pursuant to
this Agreement shall terminate automatically on the date of the Executive's

any employee benefits payable in the event of the Executive's death or
disability, whichever is applicable.

            For purposes of this Agreement, the Executive shall be deemed to be
disabled (as medically determined by an independent physician), if for a period
of at least six (6) consecutive months he is unable to perform the essential
functions of his position with the Company with or without reasonable
accommodation.

            For purposes of this Agreement, if the Executive's employment

immediately preceding paragraph.

      5.    CONFIDENTIALITY OF INFORMATION.

            (a)   Scope. During (i) the term of his employment with the Company
and for a period of thirty-six (36) months thereafter or (ii) the fifth (5th)
anniversary of the Effective Date, whichever is longer (the "Restrictive
Period"), the Executive shall not at any time, whether during or after his
employment by the Company, take or use, or otherwise disclose to anyone, any
Confidential Information, except as necessary to perform his duties hereunder,
as permitted by the President and Chief Executive Officer of the Company on the
basis of facts actually known to the President and Chief Executive Officer, or
as required by any court or governmental agency; provided, however, that this
covenant prohibits only the use and disclosure of Confidential Information and
shall not be construed as limiting the Executive's right to undertake any other
employment or business activity. The Executive shall be prohibited from
competing with the Company only as provided in subparagraph 7(a).

            (b)   Definition. "Confidential Information" shall mean any and all
ideas, suggestions, innovations, conceptions, discoveries, inventions,
improvements, technological developments, methods, processes, specifications,
formulae, compositions, techniques, systems, machines, devices, computer
software and programs, notes, memoranda, work sheets, lists of actual or
potential customers and suppliers, works of authorship, products, data, and
information in any form, which concern or relate to any aspect of the actual or
contemplated business of the Company and which are stamped "confidential" or are
otherwise treated as confidential by the Company, except for trade secrets (as
defined in Section 134.90, Wisconsin Statutes) and such items as the Executive
can prove through clear and convincing evidence were in the public domain, being
publicly and openly known, prior to the date of commencement of the Executive's
employment by the Company or, subsequent to such date, became part of the public
domain, being publicly and openly known, through lawful and proper 


                                       3
<PAGE>   4
means.

            (c)   Trade Secrets. Nothing in this Agreement shall be construed as
waiving or limiting in any way the obligations of the Executive or the rights of
the Company under Section 134.90, Wisconsin Statutes, with respect to any trade
secrets of the Company.

      6.    INVENTIONS AND COPYRIGHT WORKS.

            (a)   Scope. All Inventions or copyright works relating to the
Company's business which the Executive has conceived or made, or conceives or
makes, while employed by the Company shall be the Company's property. Any
Invention relating to the Company's business which is disclosed by the Executive
within one year following the termination of employment shall also be the
Company's property, unless it is proved through clear and convincing evidence to
have been conceived following the termination of the Executive's employment. Any
copyright works relating to the Company's business created by the Executive
during the term of employment shall be considered works made for hire and the
initial ownership therein shall be in the Company. When requested by the
Company, whether during or after employment, the Executive will execute patent
applications and other instruments as considered necessary by the Company to
apply for and obtain patents in the United States and foreign countries which
cover such Inventions. The Executive will make assignments and execute any other
instruments necessary to convey to the Company the ownership and exclusive
rights in such Inventions, copyright works, patent applications and patents. The
Company shall bear all out-of-pocket expenses connected with such patents,
patent applications, copyright applications and maintenance of patent
protection. If Inventions are made by the Executive during the course of
employment which are brought to the attention of the Company, and if the Company
shall in writing waive its rights to obtain ownership of such Inventions, the
Executive shall then have the right to file patent applications to protect such
Inventions, and to dispose of such patent rights as the Executive deems
desirable, subject to a perpetual shop right in the Company to use such
Inventions in its business without royalty.

            This Agreement does not apply to, and shall not require the
assignment to the Company of, any invention for which no equipment, supplies,
facilities or trade secret information of the Company were used and which does
not (1) relate to the business of the Company or to the Company's actual or
demonstrably anticipated research or development or (2) result from any work
performed by the Executive for the Company.

            (b)   Definition. "Invention" means any inventions, improvements,
discoveries, computer programs, know-how or ideas (whether or not patentable or
subject to copyright protection) of the Executive which are included in any of
the following classes: those for which any equipment, supplies, facilities or
trade secret information of the Company were used; those which were developed in
any part on the Company's time; or those which (1) relate to the reasonably
foreseeable business interest of the Company or the Company's actual or
reasonable anticipated research or development, and (2) result from work
performed by the Executive for the Company.

      7.    COVENANT NOT TO COMPETE.

            (a)   Scope. For a period of one (1) year from the date of
termination of Executive's employment, the Executive shall not, directly or
indirectly:

                  (1)   for or on behalf of any person or business enterprise


                                       4
<PAGE>   5
      that is in any respect "competitive with the business of the Company",
      solicit any entity or person that was a customer or known prospective
      customer of the Company during the twelve (12) month period immediately
      prior to the termination of the Executive's employment with the Company,
      or

                  (2)   undertake any employment or activity, in any capacity
      which relates to the Executive's activities or job responsibilities while
      employed by the Company, in connection with any business "competitive with
      the business of the Company" within any state, territory or possession of
      the United States, or any substantially comparable political subdivision
      of any other country, wherein the Company conducted any business during
      the twelve (12) month period immediately prior to the termination of the
      Executive's employment with the Company, irrespective of where the
      Executive renders such services.

For purposes of this Agreement, "competitive with the business of the Company"
means competitive with commercial or development activities undertaken by the
Company at the employment termination date of the Executive.

            (b)   Reform. If a court of competent jurisdiction should declare
any or all of this Agreement unenforceable because of any unreasonable
restriction of duration and/or geographical area in subparagraph 7(a), then such
court shall have the express authority to reform subparagraph 7(a) to provide
for reasonable restrictions and/or to grant the Company such other relief, at
law or in equity, as are reasonably necessary to protect the interests of the
Company.

      8.    NONSOLICITATION OF EMPLOYEES. For a period of one (1) year from the
date of termination of Executive's employment (except in the normal course of
the Company's business), the Executive shall not, directly or indirectly, induce
or attempt to influence any employee of the Company or any affiliate of the
Company to terminate his or her employment with the Company or any affiliate of
the Company or to work for the Executive or any other person or entity.

      9.    RESPONSIBILITIES UPON TERMINATION. Upon the termination of his
employment by the Company for whatever reason and irrespective of whether or not
such termination is voluntary on his part:

            (a)   the Executive shall promptly deliver to the Company all of its
data, designs, drawings, plans, manuals, notes, memoranda, work sheets,
specifications, customer lists, supplier lists, computer programs, and all other
materials which are or have become the property of the Company and all copies or
reproductions of any such; and

            (b)   the Executive shall advise the Company of the identity of any
new competitive employer within ten (10) days after accepting new employment.

      10.   SEPARATE AGREEMENTS.

            (a)   Enforcement. The covenants of the Executive contained in
paragraphs 5, 6, 7, 8 and 9 of this Agreement shall be construed as separate
agreements independent of any other agreement, claim or cause of action of the
Executive against the Company, whether predicated on this Agreement or
otherwise, and no other agreement, claim or cause of action asserted by the
Executive shall constitute a defense to the enforcement by the Company of 


                                       5
<PAGE>   6
these covenants. The covenants contained in this Agreement are necessary to
protect the legitimate business interests of the Company. Damages for the
violation of any such covenants will not give full and sufficient relief to the
Company. In the event of any violation of any such covenants, the Company shall
be entitled (i) to injunctive relief against the continued violation thereof,
and (ii) to its actual damages. In any dispute concerning whether or not the
Executive has violated any of such covenants, the prevailing party shall be
entitled to payment from the other party for any and all expenses, including
attorneys' fees and expenses, incurred by the prevailing party in connection
with such dispute.

            (b)   Scope. For purposes of the covenants in paragraphs 5, 6, 7, 8
and 9 of this Agreement, the term "Company" shall be deemed to include Burdick,
such that the nondisclosure, invention, noncompetiton and nonsolicitation
provisions shall extend to Burdick as well as the Company.

      11.   GENERAL.

            (a)   Survival. The covenants of the Executive contained in
paragraphs 5, 6, 7, 8, and 9 shall survive the term of the Executive's
employment under this Agreement after the expiration or termination of such
term.

extent necessary to render the same enforceable or valid. The unenforceability

could then continue to conform with the purposes of this Agreement and the terms
and requirements of applicable law.
