     ITEM 1.  BUSINESS


 
     Overview

          Marquette Medical Systems, Inc. (including its subsidiaries, the
     "Company" or "Marquette") is a worldwide leader in the development and
     manufacture of medical equipment and integrated systems for patient
     monitoring and diagnostic cardiology applications.  Marquette also develops
     clinical information systems, designed to be integrated with medical
     equipment, consisting of hardware and software used by integrated health
     care delivery networks and individual hospitals to electronically acquire,
     record, store, analyze and distribute patient medical data.  The Company
     believes that its ability to offer integrated clinical information systems
     and patient monitoring and diagnostic cardiology equipment provides it with
     significant competitive advantages over companies that market only
     equipment or clinical information systems.  The Company has made a
     substantial commitment to research and development and is well known for
     its technological innovation and quality, dating back to 1965 when it
     introduced the first centralized ECG processing and storage system.

          Patient monitoring systems and diagnostic cardiology products
     accounted for approximately 48% and 33% of net sales, respectively, for the
     year ended April 30, 1997 ("Fiscal 1997") with the remaining 19% of net
     sales relating to supplies and after market services.  The Company's
     products are sold in more than 65 countries throughout the world, with the
     U.S. and international markets accounting for approximately 61% and 39%,
     respectively, of net sales for Fiscal 1997. The Company's products are used
     principally in critical and intensive care units, operating and recovery
     rooms, step-down units, labor and delivery units, the cardiology
     department, the Cath Lab and related areas of acute care hospitals.  In
     addition, Marquette products increasingly are being used in smaller
     hospitals, medical clinics, outpatient surgery centers, physician offices
     and the home.

          The Company estimates that the worldwide market for patient monitoring
     systems is approximately $1.6 billion, of which approximately $800 million
     is attributable to the U.S.  Marquette's patient monitoring systems
     continuously acquire, analyze, store, display and print patient
     physiological information, providing attending medical personnel a means to
     continuously evaluate a patient's condition.  Patient monitoring systems
     include bedside, telemetry, anesthetic and respiratory gas, maternal/fetal,
     neonatal and

                                       2
<PAGE>
 
     home care and clinical information systems.  The Company believes it is one
     of the leading manufacturers of maternal/fetal, bedside and telemetry
     monitoring systems.  The Company offers fully integrated, networked, open
     architecture clinical information systems that process information obtained
     from patient monitors and various other sources, including Marquette's and
     other companies' products, to create an interactive electronic patient
     medical record.

          The Company estimates that the worldwide market for diagnostic
     cardiology products is approximately $1 billion, of which approximately
     $430 million is attributable to the U.S.  Marquette's diagnostic cardiology
     products are used to diagnose cardiac disorders through the detection,
     recording and analysis of electrical signals and other information relating
     to the heart.  These include resting, exercise testing and Holter
     (ambulatory) ECG equipment, cardiovascular information systems, cardiac
     defibrillators, cardiac catheterization laboratory monitors, and photo
     image and digital image processing equipment.  The Company believes it is
     one of the leading manufacturers of cardiovascular information systems and
     cardiac catheterization laboratory monitors.  The Company offers an open
     architecture cardiovascular information system that accepts and stores data
     from electrocardiographs and other diagnostic cardiology products to create
     a patient-specific cardiology database for comparative and other purposes.

     Addressing Market Needs

          Health care providers are increasingly differentiating medical
     equipment vendors based on their ability to provide clinical management and
     patient administration systems that deliver better quality care at lower
     costs.  Marquette is addressing these market needs with a total systems
     approach based on a combination of its broad product lines, open
     architecture Unity Network and its clinical process expertise.

          Marquette's Unity Network is an integrated system which enables a wide
     range of patient monitoring, diagnostic cardiology and clinical information
     systems to be interconnected and to interface with hospital information
     systems maintained by its customers.  Reports can be generated that provide
     the data in both clinical and administrative form to aid in improving the
     quality of care in the most cost effective manner.  The Unity Network is
     designed to (i) communicate patient information from bedside and telemetry
     monitors to central nurses' stations, (ii) allow clinicians to view patient
     information from various areas of the hospital or from remote locations via
     telephone lines and modems, and (iii) electronically transfer patient
     information

                                       3
<PAGE>
 
     to care units, outpatient facilities or physicians' offices.

          Marquette differentiates itself from other medical equipment vendors
     by addressing market needs with a total solutions approach:

          First, Marquette offers its customers a broad product line and the
     ability to equip and supply multiple areas along the continuum of care,
     thereby enabling integrated health care delivery networks and hospitals to
     gain efficiencies through standardization with a single vendor.

          Second, Marquette offers its customers the ability to construct an
     information network infrastructure and clinical information systems to
     enhance the utilization and clinical value of the Company's patient
     monitoring and diagnostic cardiology products as well as other medical
     equipment vendors' products to which the Unity Network can be interfaced.

          Third, Marquette provides its customers expertise in clinical problem
     solving, systems integration and process improvement to customize the
     configuration of the Company's products and systems to optimize clinical
     applications for the customers' various care areas and patient management
     needs.

     Business Strategy

          The Company's objective is to be the premier provider of medical
     systems for patient monitoring and diagnostic cardiology across the
     continuum of care.  The elements of the Company's strategy to achieve this
     objective are identified below.
 
          Enter New Care Areas.  The Company seeks to capitalize on the shift
     from critical care to subacute care, physician offices and home care
     through the introduction of newly designed patient monitoring and
     diagnostic cardiology products aimed specifically at these evolving care
     areas.  The Company believes that there is a greater potential for growth
     in these care areas than in the hospital market in which the Company's
     products have historically been sold.  The Company is developing new
     products that address the functional needs of these lower acuity care areas
     based on the Company's technological expertise developed in connection with
     its hospital products.

          Broaden and Enhance Existing Product Lines.  The Company is adding
     depth to its product lines by introducing products at lower price points.
     The Company has implemented this strategy by developing

                                       4
<PAGE>
 
     products internally, forming strategic alliances and through acquisitions.
     For example, as part of the E for M acquisition, the Company obtained
     Hellige's development efforts relating to a high performance, compact,
     portable, battery-powered, multiparameter patient monitor.

          Continue Development of Clinical Information Systems.  The networking
     of the Company's products through clinical information systems enhances the
     value of the Company's products to customers and will continue to be a
     focus of the Company's product development efforts.  The Company believes
     that the development of expanded clinical information systems capabilities
     is an important element of Marquette's competitive advantage in the patient
     monitoring and diagnostic cardiology markets.

          Increase Penetration of International Markets.  International sales
     have increased from approximately 33% of net sales for the year ended April
     30, 1996 ("Fiscal 1996") to approximately 39% of net sales for Fiscal 1997
     primarily due to the acquisition of E for M.  The Company will continue to
     seek greater penetration of the European market, where the E for M
     acquisition has substantially broadened the Company's distribution network.
     The Asia/Pacific market accounted for approximately 7% of the Company's net
     sales for Fiscal 1997 and has been identified by the Company as an area for
     potential growth.

          Increase Recurring Revenue Streams.  The Company is focused on
     increasing its recurring revenue by actively developing the disposable
     supplies market for the products it sells.  The Company seeks to continue
     to leverage its installed based to further increase sales of supplies and
     services related to its equipment.  Additionally, the Company seeks to
     leverage the brand-name recognition generated through its equipment sales
     to increase sales of technology-distinguished supplies related to a broad
     range of medical products manufactured by the Company and others.

          Enhance Profit Margins.  The Company continually seeks to improve
     gross margins by increasing capacity utilization at existing manufacturing
     facilities and utilizing global purchasing contracts to reduce material and
     component costs.  Additionally, the Company seeks to control operating
     costs such as engineering and general and administrative expenses relative
     to sales growth in order to increase operating margins.

                                       5

     Patient Monitoring

          Marquette's patient monitoring systems continuously acquire, analyze,
     store, display and print patient physiological information such as ECGs,
     pulse rate, blood pressure, temperature, gas measurements, respiration rate
     and oxygen saturation in the blood. This information provides attending
     medical personnel a means to continuously evaluate a patient's condition.

          The Company estimates the worldwide market for patient monitoring is
     approximately $1.6 billion, of which approximately $800 million is
     attributable to the U.S.  Recent market growth has been driven principally
     by demographic trends resulting in larger numbers of ill and elderly
     patients. Future market growth is also expected to result from emerging
     monitoring demand in new care areas which previously did not use or require
     monitoring.  As health care providers seek to reduce costs, significant
     portions of patient care are being delivered in lower acuity care areas.
     Many patients who in the past would have remained in the intensive care
     unit and received care with a 1:1 patient-to-nurse ratio for extended
     periods of time are being moved to lower acuity care areas with a 4:1 or
     6:1 patient-to-nurse ratio in which portable monitors or telemetry is used.
     These areas, which include step-down and subacute areas of hospitals,
     outpatient care facilities and home care, are expected to provide
     significant growth opportunities.

          Marquette has leveraged its expertise in microprocessor design,
     advanced circuit development and software programming to establish itself
     as a global leader in physiological data acquisition and analysis.  The
     Company has well known core competencies in ECG signal acquisition and
     analysis, pulse oximetry monitoring, invasive and non-invasive blood
     pressure measurement, cardiac output determination and respiratory gas
     analysis, and is actively involved in the advancement of measurement
     techniques and algorithms in these areas.

          In May 1994 the Company acquired Corometrics Medical Systems, Inc.
     ("Corometrics"), a designer and manufacturer of fetal and neonatal
     monitoring systems, and one of the leading providers of clinical
     information systems for labor and delivery applications.  The Corometrics
     acquisition allowed the Company to expand its product offerings to the
     labor and delivery care area with a well recognized trade name and an
     established market position.  The Company believes that its Corometrics and
     Marquette brand names are widely recognized for excellence and innovation
     in the patient monitoring sector.

          Modular Bedside Monitors are used to continuously acquire, analyze and
     monitor physiological information from critically ill patients located in
     intensive and critical care units and operating rooms.  These devices use
     multiple software modules for separate physiological parameters to adjust
     the device configuration at the point of care to meet the monitoring needs
     and acuity of any particular patient.

          The Solar 8000, the Company's principal modular bedside monitor,
     features a hardware base which offers the user the flexibility to choose
     among various features and capabilities, including acquisition and analysis
     of 12-lead ECGs and point-of-care blood gas analysis,

                                       7
<PAGE>
 
     through the addition of software modules.  A new single parameter Solar
     module library can be configured for between one and eight physiological
     parameters to meet a full range of monitoring configuration needs.

          Marquette recently introduced the Solar 9000, a more advanced modular
     bedside monitor that provides local area network computer and internet
     connection capabilities.  Initially, the Solar 9000 is targeted to
     operating rooms that require combined vital signs monitoring and clinical
     information management.

          Configured Bedside Monitors are very similar to the modular bedside
     monitors in their continuous vital signs monitoring capabilities.  However,
     they do not permit point-of-care configurability.  In most cases, these
     devices are used to monitor patients in less acute settings or in places
     where general purpose monitoring is needed, such as post-anesthesia
     care/recovery units or the emergency department.

          The Company offers the Eagle 4000, 3000 and 1000 configured bedside
     monitors.  The Eagle 4000 is the most advanced of these products and is
     capable of monitoring 12-lead ECGs, (including the ST segment of the ECG
     waveform) and carbon dioxide levels.  The Eagle 3000 is lower priced and
     offers fewer features than the Eagle 4000.  The Company believes that the
     current features of the Eagle 3000, together with its lower price compared
     to the Eagle 4000, should enable the Eagle 3000 to further penetrate the
     configured bedside monitor market. The Eagle 1000 is a low cost battery-
     powered portable monitor that is available in a variety of configurations
     and is especially well suited to compete in cost sensitive markets outside
     the U.S.

          Telemetry Monitoring Systems continuously collect ECGs from a device
     worn by the patient and transmit the data via radio frequency to a central
     receiver unit and viewing station.  These systems are designed for patients
     who are not confined to their beds, which generally includes post-operative
     patients and others in the recovery process.  Telemetry monitoring systems
     represent an increasing share of the market for monitoring equipment
     because they allow patients to be ambulatory, which facilitates earlier
     discharge from the hospital.

          Marquette competes in this category with its CD-Telemetry LAN System
     and APEX Telemetry Transmitter.  The Company has entered into several
     recent strategic alliances which add patient and staff tracking and
     location capabilities, and clinician/caregiver paging with alarm

                                       8

     event view on the pager.

          Anesthetic and Respiratory Gas Monitoring Equipment are used in tandem
     with the Company's other vital sign monitors and diagnostic products for
     cardiopulmonary monitoring in anesthesia, post-operative recovery, critical
     care and pulmonary function laboratories.  Gas monitoring products are used
     to verify the accuracy of anesthetic gas vaporizers and delivery systems
     before, during and after surgery, and measure pulmonary functions such as
     oxygenation and ventilation.  Gas monitors also detect potentially life-
     threatening conditions such as hyperventilation (excessive pulmonary gas
     exchange), hypoventilation (inadequate pulmonary gas exchange), pulmonary
     air embolus (air bubbles in the pulmonary blood stream), and equipment
     malfunction during surgery.

          The Company offers products using two methodologies for multiple gas
     detection and analysis:  mass spectrometry and infrared spectroscopy.  The
     Company's mass spectrometry product, the RAMS, provides a comprehensive
     analysis of gases administered/monitored during surgery.  The Company's
     infrared spectroscopy product, consisting of the SAM IR Anesthetic Agent
     Modules, allows for cost-effective intraoperative monitoring of anesthetic
     agents, carbon dioxide, and oxygen.

          Maternal/Fetal Monitoring Equipment provides electronic monitoring of
     the fetal heart rate and uterine activity as well as maternal parameters
     such as ECG, non-invasive blood pressure and pulse oximetry.  The Company
     offers a broad line of Corometrics brand perinatal products used in
     hospitals, physician offices and other clinical settings for care of mother
     and child during pregnancy (antepartum) and delivery (intrapartum).

          The antepartum monitors, Models 145, 150 and 155 offer a full range of
     non-invasive fetal surveillance throughout high risk pregnancies.  The
     ability to offer dual ultrasound heart rate for twin monitoring, external
     uterine contraction monitoring and electronic fetal movement detection
     allows flexibility in assessing fetal well-being during pregnancy.

          The intrapartum monitors, Models 151, 118 and 340 Telemetry allow for
     both non-invasive and invasive fetal ECG monitoring and uterine
     contractions.  In addition, the Model 118 was the first product to combine
     fetal monitoring with maternal vital signs, non-invasive blood pressure and
     oxygen saturation.  This combined maternal/fetal monitor allows assessment
     of the maternal and fetal response to labor events

                                       9
<PAGE>
 
     which may affect the intrauterine environment, including anesthesia,
     induction of labor and recovery of the mother.  The Model 118 is ideally
     suited to the new concept in obstetrical care of providing labor, delivery,
     recovery and postpartum (LDRP) in one room.  The Model 120 series expands
     the capability of the Model 118 and provides a display of maternal ECG
     waveforms.  This feature allows the clinician advanced monitoring
     capability.  The Model 340 Telemetry system allows ambulatory patients to
     be monitored during labor.

          Neonatal Monitoring Equipment provides continuous monitoring of
     neonates and allows clinicians to record, analyze and react to a neonate's
     changing conditions.  The Company's neonatal product line meets the
     monitoring requirements of the less critical to the most critically ill
     neonate.  These monitors are capable of displaying multiple measurements
     such as ECG, respiration, invasive pressures, temperatures, pulse oximetry
     and non-invasive blood pressure.  Using the Eagle and Solar monitoring
     platforms, the Corometrics brand products have added neonatal features such
     as superior respiration detection algorithms and trending, thereby
     customizing these monitors to the needs of the neonate in the neonatal
     intensive care unit.  In addition, the more compact and cost effective
     Model 556 monitor is designed for lower acuity nurseries.

          Home Care Monitoring Equipment incorporates the technological advances
     of the Corometrics brand hospital based monitors with the simplicity that
     home use requires.  Corometrics introduced the first battery backup and
     internal memory apnea monitor in the 1980s.  In 1995, the Model 510/511
     became the first apnea monitor with integrated pulse oximetry cleared by
     the FDA for use in the home, and the Company believes the Model 510/511
     remains the only monitor of its kind on the market today.  The 500 series
     of apnea products and Event-Link software allows home care clinicians to
     collect, store and analyze monitoring data to provide objective
     documentation of alarm cause and effect, allowing more cost efficient care
     of the patient in the home.

          Clinical Information Systems integrate and store data coming from
     multiple patient care areas.  The data can be charted, reviewed and
     presented in hospital selected formats that provide clinicians with a
     comprehensive overview of patient status.  Reports can then be generated
     that provide the data in both clinical and administrative form to aid in
     improving the quality of care in the most effective manner.

          The Company's product platform, the QS System, is designed to
     integrate data from all care areas, including labor and delivery, the

                                       10
<PAGE>
 
     neonatal intensive care unit, general floor, intensive care unit, critical
     care unit, operating room and perioperative unit.  Interfaces also exist
     for most lab and hospital information systems as well as for all Company
     patient monitoring systems and the patient monitoring products of other
     companies.  Integrated clinical applications can include remote site access
     that enables satellite hospitals, clinics and physicians to be linked to
     the centrally-located system.  The QS System can be customized to meet the
     most basic entry level requirements to the most complex whole hospital
     solutions involving wide area networks.  The Company believes that one of
     the primary advantages of the QS System is its ability to interconnect and
     interface with hospital information systems through the Unity Network.

     Diagnostic Cardiology

          Marquette's diagnostic cardiology products are used to diagnose
     cardiac disorders through the detection, recording and analysis of
     electrical signals and other information relating to the heart. Coronary
     artery disease is the leading cause of death of adult Americans today, and
     accounts for over 20 percent of the national health care budget.

          The Company estimates the worldwide market for diagnostic cardiology
     products is approximately $1 billion, of which approximately $430 million
     is attributable to the U.S.  An aging population, the increasing trend
     towards preventative rather than corrective medicine and a general
     preference for less invasive procedures are the factors expected to
     generate increased demand for the Company's diagnostic cardiology products.

          Marquette believes its cardiovascular information solution, the MUSE
     CV/TM/ information system, is one of the leading products used to store,
     manage, process and deliver the entire cardiology patient file. The system
     delivers advances in patient databasing, hospital information system
     interfaces, network connectivity, internet technology, e-mail accessibility
     and health care protocol standards.

          In January 1996, the Company acquired E for M Corporation ("E for M").
     Through the acquisition, Marquette added new cardiac imaging capabilities,
     broadened its diagnostic cardiology product line and expanded its customer
     base for cardiology systems.  E for M's product lines also include high
     quality cineangiography film and digital imaging products.  Also, the E for
     M acquisition, which included all of the stock in Hellige GmbH ("Hellige"),
     added European manufacturing, marketing and distribution facilities.  The
     acquisition of E for M

                                       11
<PAGE>
 
     allowed the Company's MUSE CV cardiovascular information system to expand
     its functionality into image and electrophysiology management. Management
     believes Marquette has the only complete Cath Lab solution providing
     electrophysiology and hemodynamic monitoring, digital imaging and
     cardiology patient information management.

          The following table provides information with respect to the Company's
     principal diagnostic cardiology products.

          Resting ECG Equipment is designed to record an ECG of a patient who is
     at rest, and are generally mounted on a wheeled cart for movement to the
     patient's bedside or elsewhere as needed.  The Company's
     electrocardiographs permit as many as 14 lead wires to be attached to
     patients, maximizing the amount of data that can be

                                       12
<PAGE>
 
     acquired.  The Company's extensive line of resting electrocardiographs is
     designed for use across the spectrum of care areas, including acute care
     hospitals, outpatient surgery centers, ambulances and physicians' offices.
     The Company's resting electrocardiographs perform immediate analysis of
     ECGs, store ECGs for further analysis and can communicate ECGs
     electronically to other electrocardiographs or other equipment, including
     cardiovascular information systems, for storage and comparison.

          Exercise Testing ECG Systems are used to diagnose cardiac disease and
     assess its severity by stressing the heart through physical exercise to
     elevate its blood flow requirement.  While this stress exists, any
     significant obstruction in the coronary arteries limits the flow of blood
     and results in cardiac dysfunction, which can be detected by a physician
     using electrocardiography.  The Company's exercise testing ECG systems are
     predominantly used in physician offices and hospitals.  The Company's
     CardioSys/TM/ system is capable of communicating ECGs electronically to
     other electrocardiographs or other equipment, including cardiovascular
     information systems, for storage and comparison.

          Holter (Ambulatory) ECG Equipment is designed to provide ECG
     information from an ambulatory patient who experiences intermittent
     symptoms such as palpitations, angina or loss of consciousness through a
     small recording device over the course of an extended period (usually 24
     hours), in or out of the hospital.  The Company has recently introduced
     MARS (Multiparameter Analysis Review Station), a new generation of Holter
     (ambulatory) ECG equipment. It combines the ability to analyze signals
     acquired from the Company's line of intensive care or telemetry monitors
     with those of a traditional Holter monitor, thus reducing the length of
     stay for many patients who might otherwise be delayed in the hospital
     waiting for tests to be performed or interpreted.

          Cardiovascular Information Systems are designed to accept data from
     outlying electrocardiographs via telephone line, diskette or direct
     connection, store hundreds of thousands of ECGs and quickly retrieve them
     for comparison with ECGs currently being reviewed.

          The Company's latest cardiovascular information system, the MUSE
     CV/TM/, is an open architecture system designed for hospitals. In addition
     to storing, analyzing and retrieving ECGs taken at rest, MUSE CV provides
     similar capability for Holter ECGs, exercise testing ECGs, and other
     testing procedures and integrates all of the Company's diagnostic
     cardiology products together through networking and computer processing,
     creating a complete cardiology patient file.  MUSE CV also provides an
     interface to the hospital's information system.  MUSE CV can generate
     billing and activity reports which can assist a hospital or other user in
     cost control and decrease the possibility of tests remaining unbilled.
     Many

                                       13
<PAGE>
 
     MUSE CV systems serve more than one hospital, with outlying hospitals
     employing workstations connected to the central MUSE CV by telephone lines,
     permitting cardiologists at the central hospital to assist in treating
     large numbers of patients in wide geographical areas.

          Cardiac Defibrillators are designed to restart the heart of victims of
     sudden cardiac arrest, a severe form of heart attack. Cardiac arrest is
     among the leading causes of death in the U.S. The highest incidence of
     cardiac arrest occurs outside the hospital.  The Company markets a number
     of defibrillator models for pre-hospital and hospital use.  Marquette's
     Model 1500 is the only pre-hospital defibrillator that provides 12-lead ECG
     acquisition and pacing, and can transmit ECGs directly to the hospital's
     cardiovascular information system.  The Company's hospital line of
     defibrillators can be used in all care areas, including the exercise
     testing lab, patient transport and the emergency department.

          Cardiac Catheterization Equipment is used in various cardiovascular
     procedures performed in the Cath Lab and the EP Lab. In vascular or
     "hemodynamic" studies, the catheter, with attached physiological sensors,
     is used to measure temperature and blood pressure in various parts of the
     heart and the surrounding circulatory system, as well as determining the
     volume of blood being pumped by the heart.  Electrophysiology studies are
     performed to evaluate the process of the conduction of electricity through
     the heart as the heart contracts and to diagnose the mechanisms of abnormal
     heart rhythm.  The Company's Midas System 8000 is the only system that
     combines complete electrophysiology and hemodynamics into one workstation,
     maximizing the utilization of the workstation.  The system is specially
     configured to assist cardiologists with fast, accurate collection and
     analysis of physiological data.

          Photo Image and Digital Image Processing Equipment is used to view the
     performance and function of a patient's coronary vasculature to assist in
     the detection, diagnosis, treatment and prevention of cardiac diseases and
     injuries, particularly in connection with cardiac catheterization.  The
     Company's photographic and digital imaging systems allow the capture,
     storage and review of these images.  The Company's photographic systems
     utilize a variety of 35mm high grade films produced under the Company's
     label by third-party manufacturers and offer a number of different
     processing chemistries.  The Company's digital image processing systems
     capture analog images from X-ray, ultrasound and other common imaging
     sources and convert them to digital images. These systems then manage the
     digitized images so they can be enhanced, quantified, reviewed in real-
     time, transmitted over networks and/or archived on CD-R media.  The Company
     does not manufacture or sell the X-ray, ultrasound or other imaging source

                                       14
<PAGE>
 
     associated with this process.

     Supplies and Disposables

          The Company manufactures, markets and distributes a broad spectrum of
     disposable supplies and disposables used primarily in conjunction with the
     Company's large installed base of patient monitoring systems and diagnostic
     cardiology products.  These products include ECG and other recording paper,
     monitoring and diagnostic electrodes, patient belts and straps, disposable
     and reusable blood pressure cuffs, disposable water traps, temperature
     probes, pulse oximetry probes and ambulatory ECG/telemetry hookup kits.  In
     addition, the Company utilizes its product expertise and manufacturing
     capacity to produce private label products for third parties.

          The Company seeks to continue to leverage its installed base to
     further increase sales of supplies and services related to its equipment.
     Additionally, the Company seeks to leverage the brand-name recognition
     generated through its equipment sales to increase sales of technology-
     distinguished supplies related to a broad range of medical products
     manufactured by the Company and others.  To implement this strategy the
     Company recently created supplies and disposable products as a separate
     division of the Company and devoted additional management resources to the
     division.

     Customer Service

          The Company's service operations are responsible for equipment
     installation at customers' sites and for the fulfillment of the Company's
     warranty and maintenance commitments.  Most equipment sold by the Company
     is fully warranted for all parts and labor for one year.  The Company
     offers a variety of post-warranty service agreements permitting customers
     to contract for the level of equipment maintenance and repair they require.

          In addition to warranty and post-warranty maintenance service, the
     Company performs circuit board repairs on a 48-hour return basis, and
     manufactures and markets replacement parts to the Company's dealers and
     equipment users.  The Company offers repair and maintenance training
     classes throughout the year for customers and dealers.  In addition, the
     Company supports customers, dealers and the Company's field personnel by
     providing telephone assistance on service problems.

          The Company has a national network of approximately 167 service
     technicians located throughout the U.S., and approximately 125 service
     technicians located in Europe.  At its operations in Germany, the Company
     operates a parts and support center for European service.  In some foreign
     countries, if direct Company field engineers and technicians are not
     conveniently located,

                                       15

     employees of local dealers provide warranty and field maintenance service.

     Research and Development

          Marquette has made a substantial commitment to product research and
     development throughout its history and has introduced major new products in
     each of its product lines during the past three years.  The Company
     expended $30.7 million, $37.3 million, and $48.1 million on research and
     development, which represented approximately 9.0%, 9.0% and 8.9% of net
     sales for the fiscal years ending April 30, 1995, 1996 and 1997,
     respectively.  Marquette has leveraged its expertise in microprocessor
     design, advanced circuit development and software programming to establish
     itself as a global leader in physiological data acquisition and analysis.
     The Company has well-known core competencies in ECG signal acquisition and
     analysis, pulse oximetry monitoring, invasive and non-invasive blood
     pressure measurement, cardiac output determination and respiratory gas
     analysis, and is actively involved in the advancement of measurement
     techniques and algorithms associated with each area.  The Company's primary
     product development efforts are carried out at the division level.  In
     addition, the Company maintains a 17,000 square foot dedicated Research and
     Development Center approximately one mile from its corporate offices in
     Milwaukee, Wisconsin.

          The Company's research and development strategy is to improve and
     expand its product line through innovative engineering and to create
     diagnostic and monitoring technologies that address problems brought to its
     attention by contacts in the medical community, particularly those
     technologies which improve quality of care and reduce costs.  For example,
     Marquette's telemetry products improve the quality of care by tracking
     ambulatory patients and alerting the nurse at the central control station
     if the patient has an event.  Additionally, the Solar 8000 modular bedside
     monitor was recently redesigned to reduce production costs by reducing the
     number of circuit boards from three to one and by utilizing an off-the-
     shelf display.  In addition, the Company seeks to be first to market with
     new products, to enter new markets and to respond to market trends.

          The Company's product engineers work closely with the Company's sales
     force and customers to modify and improve current products.  In addition,
     these engineers assist with the integration of components or technologies
     across several Company product lines to enhance product competitiveness.

                                       16

     Sales, Distribution and Marketing

          The Company's products are used principally in the critical and
     intensive care units, operating and recovery rooms, step-down units and
     related areas of acute care hospitals, particularly those institutions
     specializing in the diagnosis and treatment of heart disease, together with
     labor and delivery units.  Marquette products increasingly are also being
     used in medical clinics, outpatient surgery centers, physician offices and
     the home.

          The U.S. has been the principal geographic market for the Company's
     products.  Over the past ten years the Company has sought to develop its
     international market standing, and international sales increased from
     approximately 33% in Fiscal 1996 to approximately 39% in Fiscal 1997.  The
     Company will continue to seek greater penetration of the European market,
     where the E for M acquisition has substantially broadened the Company's
     distribution network.

          The Company has a direct sales force in the U.S. of approximately 282
     sales representatives, clinical specialists, and managers, as well as 7
     national account managers.  In addition, the Company has approximately 120
     and 8 direct sales employees in Europe and Australia, respectively, as well
     as numerous dealers in both markets.  The remaining international markets,
     primarily Japan, China, Southeast Asia, India, Latin America and Canada,
     are served by distributorship arrangements under which a local dealer buys
     products from the Company at a discount for resale within its own
     territory.

          Because most Company products are highly technical requiring extensive
     training in their application and operation, the Company's sales
     organization is organized along divisional product lines, including
     technical support groups which consist primarily of nurses, biomedical
     engineers and clinicians.  In addition, the Company believes its reputation
     in diagnostic cardiology enables it to obtain an entry to patient
     monitoring systems sales.  The Company has also designated certain senior
     sales personnel to act as "Unity Team Managers" to coordinate multiple
     product line sales to the same customer.  The Company maintains
     demonstration equipment so that sales personnel can make on-site clinical
     demonstrations for equipment sales.  The Company offers technical seminars
     and training sessions on a worldwide basis, and furnishes instruction
     manuals, maintenance manuals, operator guides, application information and
     software in foreign languages, as required.

          In recent years, many hospitals have joined buying groups or have been
     acquired by large hospital chains permitting them to negotiate with
     suppliers of hospital equipment to obtain more favorable pricing on large
     quantity purchases.  In addition, some

                                       17
<PAGE>
 
     large hospitals, chains and buying groups prefer to negotiate with a
     limited number of vendors who can provide a broad range of products used by
     the hospital or group.  While the Company believes that the existence of
     these groups will present a marketing opportunity for the Company, there
     can be no assurance that the Company will be able to negotiate purchasing
     arrangements with all of these groups or on terms that are favorable to the
     Company.  The Company currently has purchasing arrangements in place with
     many national and regional hospital systems, including Columbia/HCA
     Healthcare Corporation, Tenet Healthcare, Inc., and many purchasing groups,
     including MAGNET, AmeriNet, and CMMA (Catholic Materials Management
     Alliance), as well as with various subdivisions of the federal government.

          The Company has an arrangement with a third party leasing company
     which provides customer financing.  Under this arrangement, the Company is
     paid in full for its products, and the leasing company assumes credit
     risks.  The Company also directly provides lease financing in certain
     circumstances and equipment rentals.

          The Company also offers a Managed Use Program, permitting hospitals to
     make payments to the Company based upon the frequency of use of equipment
     by the hospital.  Under the Managed Use Program, the Company has the right
     to increase or reduce the number of equipment units deployed at the
     hospital to correlate with the degree of use of the units at the hospital.
     The Company believes that the program is being well received by the market
     and will further facilitate distribution of the Company's products by
     permitting hospitals to better correlate their equipment to their needs.

          The Company markets and distributes its supplies in the U.S. through
     an in-house telemarketing group, its national direct sales force and a
     number of dealers.  The Company distributes its supplies outside of the
     U.S. through its direct sales force in Europe, its Australian subsidiary
     and through independent dealers.

     Manufacturing

          Marquette internally controls all critical manufacturing processes,
     including state-of-the-art circuit board assembly and thick film hybrid and
     multichip module assembly, utilizing advanced assembly and subassembly
     burn-in systems.  The Company partners with major suppliers by locating
     supplier inventories on Marquette premises, thereby reducing Company
     inventory costs and improving access to technical components.

          The Company believes that its facilities are modern, well maintained
     and adequate for its present needs.  (See Item 2-Properties).

     Competition

          The markets for the Company's products have historically been highly
     competitive.  The consolidation of health care providers in the U.S. and
     the national effort to curtail increases in medical care costs have
     increased the level of competition.  Although the Company competes directly
     with other providers of medical equipment, no one company or group of
     companies competes with the Company across its full line of products.  The
     Company's primary competitors in patient information monitoring include
     Hewlett-Packard Corporation, Siemens Medical Systems, Inc., SpaceLabs
     Medical, Inc. and Datex Company, and in diagnostic cardiology include
     Hewlett-Packard Corporation, Schiller AG and Quinton Instrument Company, a
     subsidiary of American Home Products Corporation.  Certain of these
     competitors are larger and have greater financial and marketing resources
     than Marquette.  The principal competitive factors that differentiate one
     manufacturer from another in the market are a manufacturer's reputation for
     producing accurate, reliable and technically advanced products, product
     features, product line breadth, price, expected medical cost savings and
     effectiveness of sales and marketing efforts.

          The Company believes that it has a reputation for technological
     leadership and product reliability, which, with its working relationship
     with physicians at teaching and research hospitals as well as the breadth
     of its product line, have provided it with a strong competitive position.
     The Company's competitive position is strongest with respect to its
     cardiology product line and fetal and neonatal monitoring products, where
     the Company has been selling its products for the longest period of time,
     has the greatest name recognition and competes primarily on the basis of
     product features and technological advances.

     Government Regulation

          The medical devices manufactured and marketed by the Company are
     subject to extensive and rigorous regulation by the FDA and, in many
     instances, by state and foreign governments.  Under the FDC Act, the FDA
     regulates, among other things, the testing, manufacturing, labeling,
     distribution and promotion of medical devices in the U.S.  To facilitate
     compliance with the FDC Act and regulations promulgated thereunder, the
     Company, from time to time, may institute voluntary compliance actions such
     as product recalls when it believes it advisable to do so.  The failure of
     the Company to comply with FDA requirements could result in warning
     letters, injunctions, civil penalties, mandatory recall or seizure of
     products, total or partial suspension of production, the government's
     refusal to grant, or withdrawal of, marketing authorizations, and criminal
     prosecution.

          In general, before a new medical device may be marketed in the

                                       19
<PAGE>
 
     U.S., the manufacturer must obtain marketing authorization from the FDA
     through either clearance of a pre-market notification submission (a "510(k)
     submission") or approval of a pre-market approval application.  In
     addition, changes to a medical device that significantly affect the safety
     or efficacy of a marketed device are subject to FDA review and clearance or
     approval.

          The Company's products have not generally been subject to the
     comprehensive pre-market approval requirements, but are generally subject
     to pre-market notification requirements.  The FDA may grant marketing
     clearance of a new medical device pursuant to a 510(k) submission if it
     determines that the device is substantially equivalent to a predicate
     device that did not require pre-market approval.  A 510(k) submission must
     be supported by information demonstrating substantial equivalence.  The FDA
     recently has been requiring more rigorous demonstration of substantial
     equivalence than in the past, including the submission of clinical data in
     some cases.  It generally takes from four to 12 months from submission to
     obtain clearance of a 510(k) submission, but it may take longer. The FDA
     has no specific time limit by which it must respond to a pre-market
     notification submission.

          As a manufacturer of medical devices, the Company is also subject to
     certain other FDA regulations, including compliance with current good
     marketing practices ("GMPs") and similar regulations in other countries,
     which include testing, control and documentation requirements, and medical
     device reporting requirements.  The FDA recently revised its medical device
     GMP regulation, and the new regulation, which goes into effect later this
     year, permit the FDA to regulate the design as well as manufacture of
     medical devices and make a number of other significant changes in
     regulatory requirements.  Ongoing compliance with GMP and other applicable
     regulatory requirements is monitored through periodic inspections by
     federal and state agencies, including the FDA, and by comparable agencies
     in other countries.

          Federal, state and foreign regulations regarding the development,
     manufacture and sale of medical devices are subject to change.  The Company
     cannot predict what impact, if any, such changes might have on its
     business.  The Company also seeks, where appropriate, to comply with safety
     standards of Underwriters Laboratories, the Canadian Standards Association,
     the European Economic Community and other countries in which it markets
     products.

          The Company's products are used by health care providers for
     diagnostic testing services and other services for which the providers may
     seek reimbursement under the federal Medicare and Medicaid programs or from
     other governmental and private payers. Such reimbursement is subject to
     federal regulations and policies and regulations of other payers.  For
     example, the Medicare

                                       20
<PAGE>
 
     program, which reimburses hospitals and physicians for services provided to
     a significant percentage of hospital patients, places certain limitations
     on the methods and levels of reimbursement of hospitals for procedure costs
     and for capital expenditures made to purchase equipment such as that sold
     by the Company.  The Medicare program also limits the level of
     reimbursement to physicians for diagnostic tests and recently has
     instituted changes that may further limit the amount of such reimbursement
     of both facilities and physicians for services provided in connection with
     diagnostic and clinical procedures.  Federal and state regulations
     regarding the amount and manner of reimbursement are subject to change.
     National health remains a priority item on its legislative agenda and there
     are a number of bills presently being considered in both Houses of
     Congress.  The Company is unable to predict the impact, if any, that such
     change or legislation might have on its business.

          In addition to laws and regulations enforced by the FDA, the Company
     is also subject to regulation under the Occupational Safety and Health Act,
     the Environmental Protection Act, the Resource Conservation and Recovery
     Act and other present and potential future federal, state and local
     regulations.

     Product Liability and Insurance

          The use of the Company's products in the delivery of medical services
     involves the possibility of adverse effects that could expose the Company
     to product liability claims.  A recent U.S. Supreme Court decision held
     that product liability may exist despite FDA approval and future court
     decisions may also increase the Company's risk of product liability.  The
     Company is involved in various legal proceedings, including product
     liability suits of a nature considered normal to its business.  The
     Company's products are used by health care providers in connection with the
     treatment of patients, who will, on occasion, sustain injury or die as a
     result of their condition or medical treatment.  If a lawsuit is filed
     because of that occurrence, the Company, along with physicians and nurses,
     hospitals and other medical suppliers, may be named as a defendant, and
     whether or not the Company is ultimately determined to be liable, the
     Company may incur significant legal expenses.  In addition, such litigation
     could damage the Company's reputation and therefore impair its ability to
     market its products, and impair its ability to obtain product liability
     insurance or cause the premiums for such insurance to increase.  The
     Company carries product liability insurance coverage under several policies
     with an aggregate loss coverage which the Company believes is sufficient.
     However, in the future the Company may be unable to obtain adequate product
     liability coverage on acceptable terms, if at all.  A successful product
     liability claim or series of claims brought against the Company that are
     not covered by insurance or exceed policy limits could have a material
     adverse effect on the Company's business, financial condition and

                                       21
<PAGE>
 
     results of operations.

     Employees

          At April 30, 1997, the Company had approximately 2,347 employees in
     the U.S. and approximately 803 employees outside the U.S., including
     approximately 1,005 employees engaged primarily in sales, approximately 927
     employees engaged primarily in manufacturing, approximately 461 employees
     engaged primarily in research and product development and approximately 353
     employees primarily engaged in service.  Management considers employee
     relations to be excellent.

          The Company believes that high levels of employee support and
     participation significantly contribute to the Company's business success.
     Therefore, the Company has implemented various employee benefit programs
     and work-related policies.  Employees are permitted to personalize their
     work areas and determine their own flexible work schedules.  The Company
     also provides many of its employees with day care facilities, exercise
     facilities, and a tuition reimbursement program.  It also encourages direct
     and individual ownership by employees of Common Stock through its 401(k)-
     Profit Sharing Plan and grants of stock options.

                         AMENDMENT NO. 2 TO BY-LAWS OF
                        MARQUETTE MEDICAL SYSTEMS, INC.
                (Formerly Known as Marquette Electronics, Inc.)
                         (As Adopted November 20, 1996)



          1.   Article XI is hereby redesignated as Article XII and the
     following be and is hereby adopted as Article XI of the By-Laws, to-wit:

                                  "ARTICLE XI
                                  -----------
                             Conflicts of Interest
                             ---------------------

               1.   A Director shall be considered to have a conflict of
     interest if:

               (a) The Director has existing or potential financial or other
     interests which impair or might reasonably appear to impair their
     independent, unbiased judgment in the discharge of their responsibilities
     to the Corporation.

               (b) Directors are aware that a member of their family (which for
     the purposes of this paragraph shall be a spouse, parents, siblings,
     children, and any other relative if the latter resides in the same
     household as the Director) has such existing or potential or other
     interests.

               (c) Any organization in which the Director (or member of their
     family) is an officer,  director, employee, member, partner, trustee, or
     controlling stockholder has such existing or potential or other interests.

               2.   The following guidelines exist in cases where a real or
     perceived conflict of interest exists:

               (a) The Director shall disclose to the Board any possible
     conflict of interest at the earliest practical time.

               (b) No Director shall vote on any matter under consideration at a
     Board or Committee meeting, in which such director has a conflict of
     interest.

               (c) The minutes of such meeting shall reflect that a disclosure
     was made and that the Director having a conflict of interest abstained from
     voting.
<PAGE>
 
               (d) Any Director who is uncertain whether a conflict of interest
     may exist in any matter may request the Board or Committee to resolve the
     questions by majority vote."


          3.   This Amendment shall be known as Amendment No. 2 to the Amended
     and Restated By-Laws of Marquette Medical Systems, Inc.

          4.   In all other respects, the Amended and Restated By-Laws of
     Marquette Medical Systems, Inc., as adopted on January 8, 1996, and amended
     by Amendment No. 1 adopted May 21, 1996, shall remain in full force and
     effect.

               The principal office of the corporation in the State of Wisconsin
     shall be located in the City of Milwaukee, County of Milwaukee.  The
     corporation may have such other offices, either within or without the State
     of Wisconsin, as the Board of Directors may designate or as the business of
     the corporation may require from time to time.

               The registered office of the corporation required by the

                                  SHAREHOLDERS
                                  ------------

               Section 1 -- Annual Meeting.
               ---------    -------------- 

               The annual meeting of the shareholders for the election of
     directors and for the transaction of such other business as may properly be
     brought before the meeting shall be held at such time as is specified in
     the notice of the meeting on either the first Friday in July of each year
     or on such other date as may be fixed by the Board of Directors of the
     corporation prior to the giving of the notice of the meeting.  The Board of
     Directors acting by resolution may postpone or reschedule any annual
     meeting of shareholders.

               Nominations of persons for election to the Board of Directors of
     the corporation and the proposal of business to be considered by the
     shareholders may be made at an annual meeting of shareholders (a) pursuant
     to the corporation's notice of meeting, (b) by or at the direction of the
     Board of Directors or (c) by any
<PAGE>
 
     shareholder of the corporation who was a shareholder of record at the time
     of giving of notice provided for in this By-Law, who is entitled to vote at
     the meeting and who complied with the notice procedures set forth in this
     By-Law.

               For nominations or other business to be properly brought before
     an annual meeting by a shareholder pursuant to clause (c) of the foregoing
     paragraph of this By-Law, the shareholder must have given timely notice
     thereof in writing to the Secretary of the corporation.  To be timely, a
     shareholder's notice shall be delivered to the Secretary at the principal
     executive offices of the corporation not less than 75 days nor more than
     100 days prior to the first anniversary of the preceding year's annual
     meeting; provided, however, that in the event that the date of the annual
     meeting is advanced by more than 30 days or delayed by more than 60 days
     from such anniversary date, notice by the shareholder to be timely must be
     so delivered not earlier than the 100th day prior to such annual meeting
     and not later than the close of business on the later of the 75th day prior
     to such annual meeting or the 10th day following the day on which public
     announcement of the date of such meeting is first made.  Such shareholder's
     notice shall set forth (a) as to each person whom the shareholder proposes
     to nominate for election or reelection as a director all information
     relating to such person that is required to be disclosed in solicitations
     of proxies for election of directors, or is otherwise required, in each
     case pursuant to Regulation 14A under the Securities Exchange Act of 1934,
     as amended (the "Exchange Act") (including such person's written consent to
     being named in the proxy statement as a nominee and to serving as a
     director if elected); (b) as to any other business that the shareholder
     proposes to bring before the meeting, a brief description of the business
     desired to be brought before the meeting, the reasons for conducting such
     business at the meeting and any material interest in such business of such
     shareholder and the beneficial owner, if any, on whose behalf the proposal
     is made; (c) as to the shareholder giving the notice and the beneficial
     owner, if any, on whose behalf the nomination or proposal is made (i) the
     name and address of such shareholder, as they appear on the corporation's
     books, and of such beneficial owner and (ii) the class and number of shares
     of the corporation which are owned beneficially and of record by such
     shareholder and such beneficial owner.

               Notwithstanding anything in the second sentence of the preceding
     paragraph to the contrary, in the event that the number of directors to be
     elected to the Board of Directors of the corporation is increased and there
     is no public announcement naming all of the nominees for Director or
     specifying the size of the increased Board of Directors made by the
     corporation at least 85 days prior to the first anniversary of the
     preceding year's annual meeting, a shareholder's notice required by this
     By-Law shall also be considered timely, but only with respect to nominees
     for any new
<PAGE>
 
     positions created by such increase, if it shall be delivered to the
     Secretary at the principal executive offices of the corporation not later
     than the close of business on the 10th day following the day on which such
     public announcement is first made by the corporation.

               Only such persons who are nominated in accordance with the
     procedures set forth in these By-laws shall be eligible to serve as
     directors and only such business shall be conducted at an annual meeting of
     shareholders as shall have been brought before the meeting in accordance
     with the procedures set forth in this By-Law.  The chairman of the meeting
     shall have the power and duty to determine whether a nomination or any
     business proposed to be brought before the meeting was made in accordance
     with the procedures set forth in this By-Law and, if any proposed
     nomination or business is not in compliance with this By-Law, to declare
     that such defective proposal shall be disregarded.

               For purposes of this By-Law, "public announcement" shall mean
     disclosure in a press release reported by the Dow Jones News Service,
     Associated Press or comparable national news service or in a document
     publicly filed by the corporation with the Securities and Exchange
     Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.

               Notwithstanding the foregoing provisions of this By-Law, a
     shareholder shall also comply with all applicable requirements of the
     Exchange Act and the rules and regulations thereunder with respect to the
     matters set forth in this By-Law.  Nothing in this By-Law shall be deemed
     to affect any rights of shareholders to request inclusion of proposals in
     the corporation's proxy statement pursuant to Rule 14a-8 under the Exchange
     Act.

               Section 2 -- Special Meetings.
               ---------    ---------------- 

               Special meetings of the shareholders for any purpose or purposes
     shall be called to be held at any time upon the request of the President, a
     majority of the members of the Board of Directors or of the Executive
     Committee then in office or upon the written request of the holders of not
     less than ten (10%) percent of all outstanding shares of the corporation.
     Business transacted at all special meetings shall be confined to the
     specific purpose or purposes of the persons authorized to request such
     special meeting as set forth in this Section 2 and only such purpose or
     purposes will be set forth in the notice of the meeting.  The Board of
     Directors acting by resolution may postpone or reschedule any previously
     scheduled special meeting of shareholders.

               Nominations of persons for election to the Board of Directors may
     be made at a special meeting of shareholders at which directors are to be
     elected (a) pursuant to the corporation's notice of meeting, (b) by or at
     the direction of the Board of
<PAGE>
 
     Directors or (c) by any shareholder of the corporation who is a shareholder
     of record at the time of giving of notice provided for in this By-Law, who
     shall be entitled to vote at the meeting and who complies with the notice
     procedures set forth in this By-Law. Nominations by shareholders of persons
     for election to the Board of Directors may be made at such a special
     meeting of shareholders if the shareholder's notice required by the third
     paragraph of Section 1 of Article I of these By-Laws shall be delivered to
     the Secretary at the principal executive offices of the corporation not
     earlier than the 100th day prior to such special meeting and not later than
     the close of business on the later of the 75th day prior to such special
     meeting or the 10th day following the day on which such public announcement
     is first made of the date of the special meeting and of the nominees
     proposed by the Board of Directors to be elected at such meeting.

               Only such persons who are nominated in accordance with the
     procedures set forth in these By-laws shall be eligible to serve as
     directors and only such business shall be conducted at a special  meeting
     of shareholders as shall have been brought before the meeting in accordance
     with the procedures set forth in this By-Law.  The chairman of the meeting
     shall have the power and duty to determine whether a nomination or any
     business proposed to be brought before the meeting was made in accordance
     with the procedures set forth in this By-Law and, if any proposed
     nomination or business is not in compliance with this By-Law, to declare
     that such defective proposal shall be disregarded.

               Notwithstanding the foregoing provisions of this By-Law, a
     shareholder shall also comply with all applicable requirements of the
     Exchange Act and the rules and regulations thereunder with respect to the
     matters set forth in this By-Law.  Nothing in this By-Law shall be deemed
     to affect any rights of shareholders to request inclusion of proposals in
     the corporation's proxy statement pursuant to Rule 14a-8 under the Exchange
     Act.

               Section 3 -- Place of Meeting.
               ---------    ---------------- 

               All meetings of the shareholders shall be held at such place
     within or without the state of Wisconsin as shall be fixed by the Board of
     Directors from time to time.

               Section 4 -- Notice of Meeting.
               ---------    ----------------- 

               Written notice stating the place, day and hour of the meeting
     and, the purpose or purposes for which the meeting is called, shall be
     delivered not less than ten nor more than  ninety days before the date of
     the meeting, either personally or by mail, by or at the direction of the
     President, or the Secretary, or the officer or persons calling the meeting,
     to each shareholder of record entitled to vote at such meeting.  If mailed,
     such notice
<PAGE>
 
     shall be deemed to be delivered when deposited in the United States mail,
     addressed to the shareholder at his address as it appears on the stock
     record books of the corporation, with postage thereon prepaid.

               Section 5 -- Closing of Transfer Books or Fixing of
               ---------    ---------------------------------------        
                            Record Date.
                            ----------- 

               The Board of Directors may fix a future date as the record date
     for one or more voting groups in order to determine the shareholders
     entitled to notice of a shareholders meeting, to demand a special meeting,
     or to vote or to take any other action. The record date may not be more
     than seventy days nor less than fifteen days before the meeting or action
     requiring a determination of shareholders.  Except as otherwise provided by
     these By-Laws, a determination of shareholders entitled to notice of or to
     vote at a shareholders meeting is effective for any adjournment of the
     meeting unless the Board of Directors fixes a new record date, which it
     shall do if the meeting is adjourned to a date more than one hundred twenty
     days after the date fixed for the original meeting.  The Board of Directors
     may from time to time fix in advance a date, not more than seventy days
     prior to the date for the payment of any dividend, or the date for the
     allotment of any rights, or the date when any change or conversion or
     exchange of shares shall become effective, as a record for the
     determination of the shareholders entitled to receive payment of any such
     dividend, or to any such allotment of rights, or to exercise the rights in
     respect of any such change, conversion, or exchange of shares, and only
     such shareholders as shall be shareholders of record on the date so fixed
     shall be entitled to receive payment of such dividend, or to receive such
     allotment of rights, or to exercise such rights, notwithstanding any
     transfer of any shares on the books of the corporation after any such
     record date so fixed.

               Section 6 -- Shareholders' List For Meeting.
               ---------    ------------------------------ 

               After fixing a record date for a meeting, the corporation shall
     prepare a list of the names of all its shareholders who are entitled to
     notice of a shareholders meeting.  The list shall be arranged by class or
     series of shares and show the address of and number of shares held by each
     shareholder.

               The corporation shall make the shareholders' list available for
     inspection by shareholders, beginning two business days after notice of the
     meeting is given for which the list was prepared and continuing to the date
     of the meeting, at the corporation's principal office or at a place

     extent that the voting rights of the shares of any class are limited or
     denied by the Articles of Incorporation or by a resolution of the Board of
     Directors designating a series of preferred stock. At each election for
     Directors, every shareholder entitled to vote at such election shall have
     the right to vote, in person or by proxy, the number of shares owned by him
     for as many persons as there are Directors to be elected and for whose

     Except with respect to the election of Directors, and unless required by
     statute or determined by the chairman of the meeting to be advisable, the
     vote on any question need not be by ballot.  If a quorum is present at any
     meeting of shareholders, the vote of the
<PAGE>
 
     holders of a majority of the shares cast by the holders of shares entitled
     to vote on the matter shall be sufficient for the transaction of any
     business, except that directors shall be elected by a plurality of shares
     cast by the holders of shares entitled to vote in the election.

     officers of the corporation or candidates for the office of director.  Such
     Inspectors shall count and report to the meeting the votes cast on all
     matters submitted to a vote at such meeting.  In the case of failure of the
     Board of Directors to make such appointments, or in the case of failure of
     any Inspector so appointed to act, the chairman of the meeting shall make
     such appointments or fill such vacancies.  Each Inspector shall be entitled
     to a reasonable compensation from the corporation for his services.  The
     Inspectors appointed to act at any meeting of the shareholders, before
     entering upon the discharge of their duties, shall be sworn faithfully to
     execute the duties of Inspectors at such meeting with strict impartiality
     and according to the best of their ability, and the oath so taken shall be
     subscribed by them.

     other officer appointed by such president.  A proxy executed by any
     principal officer of such other corporation or assistant thereto shall be
     conclusive evidence of the signer's authority to act, in the absence of
     express notice to this corpora tion, given in writing to the secretary of
     this corporation, of the designation of some other person by the board of
     directors or the by-laws of such other corporation.

     itself or an employee of the corporation.  In case any officer who has

     may be issued by the corporation with the same effect as if he were such
     officer at the date of its issuance. There shall be set forth upon the face

     rights and preferences of subsequent series. Each certificate representing
     shares shall state upon the face thereof that the corporation is organized
     under the laws of the State of Wisconsin, the name of the person to whom
     issued, the number and class and the designation of the series, if any,
     which such certificate represents and the par value of each share
     represented by such certificate or a statement that the shares are without
     par value.  No certificate shall be issued for any share until the
     consideration therefor has been fully paid.

     destroyed upon the making of an affidavit of that fact by the person
     claiming the certificate to be lost, stolen or destroyed. When authorizing

     require the owner of such lost, stolen or destroyed certificate or
     certificates, or his legal representative, to advertise the same in such
     manner as it shall require and/or to give the corporation a bond in such

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


               1.  A Director shall be considered to have a conflict of interest
     if:

               (a) The Director has existing or potential financial or
<PAGE>
 
     other interests which impair or might reasonably appear to impair their
     independent, unbiased judgment in the discharge of their responsibilities
     to the Corporation.

               (b) Directors are aware that a member of their family (which for
     the purposes of this paragraph shall be a spouse, parents, siblings,
     children, and any other relative if the latter resides in the same
     household as the Director) has such existing or potential or other
     interests.

               (c) Any organization in which the Director (or member of their
     family) is an officer,  director, employee, member, partner, trustee, or
     controlling stockholder has such existing or potential or other interests.

               2.  The following guidelines exist in cases where a real or
     perceived conflict of interest exists:

               (a) The Director shall disclose to the Board any possible
     conflict of interest at the earliest practical time.

               (b) No Director shall vote on any matter under consideration at a
     Board or Committee meeting, in which such director has a conflict of
     interest.

               (c) The minutes of such meeting shall reflect that a disclosure
     was made and that the Director having a conflict of interest abstained from
     voting.

               (d) Any Director who is uncertain whether a conflict of interest
     may exist in any matter may request the Board or Committee to resolve the
     questions by majority vote.

                                  STOCK OPTION
                                  ------------


          This Stock Option is granted as of June 24, 1997 by MARQUETTE MEDICAL
     SYSTEMS, INC., a Wisconsin corporation ("Company"), to MICHAEL J. CUDAHY
     ("Cudahy"), pursuant to resolutions adopted by the Board of Directors of
     the Company on May 28, 1997.

               In order to give Cudahy an incentive and to induce Cudahy to
     remain in the employ of the Company, and as an active member of its Board
     of Directors,  the Company hereby grants to Cudahy an option to purchase,
     from time to time, all or any part of a total of Two Hundred Fifty Thousand
     (250,000) Class A Common Shares, Ten Cent ($.10) par value, at a price of
     $20.63 per share, upon the following terms and conditions:

          1.   The term of the option shall be for ten (10) years from the date
     hereof, and it shall expire on May 27, 2007 unless sooner terminated as
     hereinafter provided.

          2.   At any time or times (but in no event after the above expiration
     date or prior termination of this option), Cudahy may exercise this option,
     in whole or in part.

               (a) Exercise may only be made in multiples of one thousand
     (1,000) shares.

               (b) This option shall be exercised only by timely signed written
     notice delivered to the Company's Secretary or his office, in terms of the
     prescribed "Exercise of Option" form attached as Exhibit "A", specifying
     the number of shares and accompanied by payment, in cash or by check, of
     the full option purchase price therefor and any amount required to be
     withheld by the Company for Federal, state and/or local tax purposes.

               (c) The obligation of the Company to sell and deliver shares upon
     the due exercise of this option shall be subject to: (I) all applicable
     laws, rules and regulations and to such approvals of any governmental
     agencies as may be required, including but not by way of limitation, the
     effectiveness of a Registration Statement under The Securities Act of 1933,
     as amended, or the availability of an exemption from registration under the
     said Act, whichever may be deemed necessary or appro priate by counsel for
     the Company; and (ii) the satisfaction of all stock exchange or NASDAQ
     requirements, if any, necessary to accomplish the listing, complete the
     listing or qualify for trading upon which the shares of the Company may be
     listed, or NASDAQ as the case may be.
<PAGE>
 
          3.   This option, to the extent not then already exercised or
     otherwise terminated or expired, shall terminate on the one hundred
     eightieth (180th) day following  the effective date of the last to occur of
     (i) Cudahy's death or termination of employment with the Company and (ii)
     such time as he no longer serves as a Director of the Company.
<PAGE>
 
          4.   This option is not transferable other than by Will or the laws of
     descent and distribution, may be exercised during the life of Cudahy only
     by Cudahy personally, and after Cudahy's death, only to the extent, if any,
     as provided in Paragraph 3 hereof.  Any attempted transfer by Cudahy
     (voluntarily or by operation of law) shall be null and void, and this
     option shall then become null and void.

          5.   Neither this option, shares of stock issued upon the exercise of
     it, any excess of market value over option price, nor any other rights,
     profits, values or interests resulting from the granting of this option
     shall be considered as "compensation" for purposes of any present or future
     benefit plan of the Company.

          6.   In the event of any stock split, stock dividend, combination of
     shares or other capital reorganization or reclassi fication of the Company,
     which materially affects the value of the Class A Common Shares,
     appropriate adjustment in the number of shares subsequent to this option or
     to the option price per share, or both, shall be made; provided that a
     stock dividend in the amount equal to five percent (5%) or less shall not
     be deemed to materially affect the value of shares subject to this option.
     If the Company shall propose to merge into or consolidate with any other
     corporation or to enter into an agreement to sell substantially all of its
     assets, the extent not previously exercised within thirty (30) days
     following execution of the Agreement. To the extent that the option remains
     unexercised after such thirty (30) day period, the option shall be void and
     without further force or effect.

          7.   The Company hereby represents and warrants to Cudahy, that it has
     reserved and will at all times while this option is in force, have
     available sufficient shares to fulfill this option.

MARQUETTE MEDICAL SYSTEMS, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
APRIL 30, 1997, 1996 AND 1995 (Dollars In Thousands Except Per Share Data)

(1)  Nature of Operations-

     Marquette Medical Systems, Inc. (the "Company", formerly known as Marquette
     Electronics, Inc.) is a worldwide leader in the development and manufacture
     of medical equipment and integrated systems for patient monitoring and
     diagnostic cardiology applications. The Company also develops clinical
     information systems, designed to be integrated with medical equipment,
     consisting of hardware and software used by integrated health care delivery
     networks and individual hospitals to electronically acquire, record, store,
     analyze and distribute patient medical data. The Company's products are
     used principally in critical and intensive care units, operating and
     recovery rooms, step-down units, labor and delivery units, cardiology
     departments, cardiac catheterization laboratories and related areas of
     acute care hospitals. In addition, the Company's products are increasingly
     being used in smaller hospitals, medical clinics, outpatient surgery
     centers, physician offices and homes. The Company covers the United States
     market, most of Western Europe and Australia through its own sales force.
     The remainder of the international market is served by dealers.

(2)  Summary of Significant Accounting Policies-

     (a)  Basis of consolidation-

          The consolidated financial statements include the accounts of
          Marquette Medical Systems, Inc. and its foreign and domestic
          subsidiaries. All significant intercompany accounts and transactions
          have been eliminated in consolidation.

     (b)  Revenue recognition-

          Revenue is recognized on an accrual basis when equipment and supplies
          are shipped. Revenue for service contracts is recognized over the term
          of the contract, typically twelve months. Costs related to service
          contracts are expensed as incurred.

     (c)  Supplemental disclosure of cash flow information-

     (d)Inventories-
</TABLE> 
<PAGE>
 
Inventories consist of the following:
 
<TABLE>

                                                   April 30,

     Raw materials and component parts      $ 31,629     $ 35,716
     Work-in-process and finished goods       56,434       45,869
     Inventory on loan or consignment         22,716       24,583
                                            $110,779     $106,168
</TABLE>
<PAGE>
 
For its domestic inventories (representing 72% and 61% of total inventories at
April 30, 1997 and 1996, respectively), the Company employs the last-in, first-
out (LIFO) cost method. The first-in, first-out (FIFO) cost method is used for
all remaining inventories. If the FIFO cost method had been used for domestic
inventories instead of the LIFO cost method, the carrying value assigned to
inventories would have been $2,206 and $1,962 less at April 30, 1997 and 1996,
respectively.

     (e)  Property and equipment-
          Property and equipment, along with improvements that significantly
          extend the useful life of existing assets, are carried at cost.
          Depreciation is provided on the straight-line method over the
          estimated useful lives of the assets which range from 15-20 years for
          land improvements, 40-50 years for buildings and 3-7 years for
          equipment.

     (f)  Engineering expenses- 
          Engineering expenses represent research and development costs and are
          charged to operations as incurred. The Company also charged to
          operations $35,700 related to the write-off of acquired in-process
          research and development attributable to the E for M acquisition in
          fiscal 1996. See Note 3 for further discussion of purchased research
          and development costs.

     (g)  Advertising costs-
          Advertising costs are charged to operations as incurred. Such charges
          were $3,541, $2,260 and $1,691 in fiscal 1997, 1996 and 1995,
          respectively.

     (h)  Cash and cash equivalents-
          For purposes of the consolidated statements of cash flows, the Company
          considers all highly liquid investments with a maturity of three
          months or less at the time of purchase to be cash equivalents.

     (i)  Foreign currency-
          Asset and liability accounts of the Company's foreign operations are
          translated at the current exchange rate, and income and expense
          accounts are translated at the average of the monthly exchange rates.
          Gains and losses resulting from the translation of foreign currency
          financial statements are classified as a separate component of
          shareholders' equity.

Foreign currency transaction gains (losses) totalling $1,811, $744 and $124 are
included in other income in the consolidated statements of income for fiscal
1997, 1996 and 1995, respectively.

As a hedge against foreign accounts payable, the Company at times has entered
into various forward exchange contracts to exchange foreign currencies for
United States dollars at a fixed contract rate. Market value gains and losses
resulting from these contracts are recognized in the consolidated statements of
income and offset foreign exchange gains or losses on the foreign payables at
their maturity date. As of April 30, 1997, the Company has three such contracts
to exchange various foreign currencies for a total contract amount of $2,296 and
a maturity date of May 30, 1997. The carrying value of these contracts
approximates fair value.

     (j)  Net income per Class A
          common share-
          Class C Common Stock participates in income with Class A Common Stock
          in the ratio of 1:100. In December, 1996, all 26,250,000 outstanding
          shares of the Company's Class C common shares, $0.01 par value, were
<PAGE>
 
          exchanged for 262,500 shares of Class A common stock.

          The weighted average shares for calculating net income per Class A
          common share is equal to the sum of the weighted average number of
          shares of Class A Common Stock outstanding and 1/100 of the weighted
          average number of shares of Class C Common Stock outstanding during
          the year. Such weighted average shares were 16,452,000, 16,254,000 and
          16,172,000 for fiscal 1997, 1996 and 1995, respectively.

          In March, 1997, the Financial Accounting Standards Board ("FASB")
          issued SFAS No. 128 "Earnings per Share." The Company will adopt this
          statement in fiscal 1998. However, the pro forma earnings per share
          for fiscal 1997, 1996 and 1995 under this statement would have been as
          follows:
<TABLE>

                                                Year Ended April 30,
                                                 1997     1996    1995

               Per share amounts
                  Basic EPS as reported          $1.29   $(1.53)  $1.21
                  Effect of SFAS No. 128          (.02)      --    (.02)
                  Diluted EPS as restated        $1.27   $(1.53)  $1.19
     (k) Goodwill-
</TABLE>

          The excess of the purchase cost over the fair value of net assets
          acquired is being amortized over a range of 15-20 years on a straight-
          line basis. The Company continually evaluates whether later events and
          circumstances have occurred that indicate the remaining estimated
          useful life of goodwill may warrant revision or that the remaining
          balance of goodwill may not be recoverable. When factors indicate that
          goodwill should be evaluated for possible impairment, the Company uses
          an estimate of the related business segment's discounted net cash
          flows over the remaining life of the goodwill in measuring whether the
          goodwill is recoverable. Goodwill (net of accumulated amortization)
          was $39,984 and $45,882 at April 30, 1997 and 1996, respectively.
          Amortization of goodwill was $3,193 in fiscal 1997, $2,453 in fiscal
          1996, and $1,871 in fiscal 1995. See Note 3 for further discussion
          related to the goodwill attributable to the E for M and Corometrics
          acquisitions.

          In March, 1995, FASB issued SFAS No. 121 "Accounting for the
          Impairment of Long-Lived Assets and for Long-Lived Assets to be
          Disposed Of", which addresses accounting for the impairment of long-
          lived assets that either will be held and used in operations or that
          will be disposed of. The Company adopted this statement on May 1, 1996
          with no material impact on the financial position or results of
          operations of the Company.

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

     (m)  Reclassification of prior year amounts-
          Certain prior year amounts have been reclassified to conform with
          current year presentations.

(3)  Acquisition of Corometrics Medical Systems, Inc. and E for M Corporation-
     On May 31, 1994, the Company acquired 100% of the common stock of
     Corometrics Medical Systems, Inc. ("Corometrics"), a manufacturer of fetal
     monitors and related products. The purchase price was approximately $70,800
     and was paid in cash. Related to this purchase, the Company borrowed
     $49,200 under a bank loan
<PAGE>
 
     agreement. As of April 30, 1996, these borrowings have been paid in full.
     The acquisition has been accounted for as a purchase, and the excess of the
     purchase price over the fair value of net assets acquired has been
     allocated to goodwill. The value of such goodwill is $23,230.

     Effective January 1, 1996, the Company acquired 100% of the common stock of
     E for M Corporation ("E for M"), an international medical equipment,
     software and supplies company serving patient monitoring and cardiology,
     which includes cardiac catheterization and electrophysiology laboratories.
     The purchase price was approximately $93,400 and was paid in cash and
     through the issuance of stock options. The Company converted outstanding
     options for E for M stock into options for Marquette stock as part of the
     transaction. The fair value of the converted options was $3,083. Related to
     this purchase, the Company borrowed $90,000 under bank loan agreements
     payable periodically over the next five years. The acquisition has been
     accounted for as a purchase and the excess of the purchase price over the
     fair value of the net assets acquired has been allocated to goodwill. The
     value of such goodwill is $26,022. In addition, the Company acquired
     intangible assets related to in-process research and development (R&D),
     product technologies and tradenames with values of $35,700, $12,672 and
     $8,468, respectively. The acquired in-process R&D was entirely written-off
     during the year. The remaining intangibles have estimated useful lives
     ranging from 7 to 40 years.

     In connection with the acquisition, the Company implemented a restructuring
     plan for the purpose of integrating the E for M operation into the
     Company's existing operations. This restructuring plan included
     consolidation of facilities as well as a reduction in the number of
     employees required for the combined operations. The costs expected to be
     incurred with respect to this restructuring plan were recorded as
     liabilities of E for M which were assumed in the purchase transaction. The
     total restructuring charges attributable to E for M were $10,120, of which
     $8,447 was estimated at the time of the acquisition in fiscal 1996. An
     additional $1,673 was recorded in fiscal 1997 as a change in estimate. The
     total charges include $7,205 of severance costs, $992 of dealer termination
     costs and $1,923 of facility closing, legal and other costs.

     As of April 30, 1997 and 1996, $1,537 and $7,662, respectively, of the
     restructuring charges remained in "Other current liabilities" in the
     Consolidated Balance Sheets. Unaudited pro-forma results of operations,
     assuming the acquisition of both Corometrics and E for M as of May 1, 1994,
     and the $35,700 write-off of acquired in-process R&D in fiscal 1996, would
     be as follows:

 (4) Income Taxes-

     Deferred income taxes are recorded to reflect the tax consequences on
     future years on differences between the tax basis of assets and liabilities
     and their financial reporting amounts at fiscal year end. Deferred tax

<PAGE>
 
     Company to maintain a minimum tangible net worth, a minimum interest
     coverage ratio and a maximum liabilities to tangible net worth ratio. The
     Company was in compliance with all such covenants at April 30, 1997.

(7)  Commitments and Contingencies-

     The Company leases plant, office space, and automobiles under various
     operating lease agreements. Minimum rental commitments under leases having

     Various lawsuits and claims are pending against the Company. Although the
     outcome of such lawsuits and claims cannot be predicted with certainty, the
     resolution of these lawsuits and claims will not, in the opinion of
     management, result in a material adverse effect on the financial position
     or results of operations of the Company.

(8)  Shareholders' Equity-
     In March, 1997, the Company sold, through an underwritten public offering,
     1,373,422 Class A common shares at a net price of $17.37 per share. The net
     proceeds of this offering were used to repay existing bank debt.

     In December, 1996, the Company adopted a shareholder rights plan and
     declared a dividend of one preferred share purchase right on each
     outstanding share of the Company's Class A Common Stock. Under certain
     conditions, each right may be exercised to purchase one one-hundredth share
     of a new series of nonredeemable preferred stock at an exercise price of
     $80, subject to adjustment. The rights may be exercised only after a public
     announcement that a party acquired or will make a tender offer to acquire
     20% or more of the Company's common stock. The rights, which do not have
     voting rights, expire on December 18, 2006 and may be redeemed by the
     Company at a price of $0.01 per right at any time prior to their expiration
     or the acquisition of 20% of the Company's common stock. 

     In the event that the Company is acquired in a merger or other business
     combination transaction, provisions shall be made so that each holder of a
     right shall have the right to receive, upon exercise thereof at the then
     current exercise price, the number of shares of common stock of the
     surviving company which at the time of such transaction would have a market
     value of two times the exercise price of the right.

9)   Stock Option Plans-

     The Company has reserved 3,500,000 shares of Class A Common Stock for
     issuance under the Amended and Restated Stock Option Plan for Employees of
     Marquette Medical Systems, Inc. (the "Plan"). Under the Plan, incentive
     options may be granted to purchase shares at or above fair market value on
     the date of grant and expire within ten years, and non-qualified options
     may be granted at or above 85% of fair market value on the date of grant
     and expire within fifteen years. If stock options granted under the Plan

<PAGE>
 
      expire or otherwise terminate without being exercised, the Class A Common
      Stock not issued under such stock options shall again become available for
      issuance under the Plan.

     The Company has reserved 276,042 shares of Class A Common Stock for
     issuance under the E for M 1991 Stock Option Plan and E for M 1991 Key
     Employee Stock Option Plan. The E for M stock options outstanding on the
     acquisition date were converted into stock options of the Company in
     conjunction with the acquisition. Each option converted by the Company
     continues to have, and is subject to, the same terms and conditions set
     forth in E for M's stock option plan prior to the acquisition. The E for M
     stock options were converted into 276,042 stock options of the Company
     pursuant to this plan based on an exchange ratio of the average price of
     Marquette stock at the acquisition date to the tender price of E for M
     stock .

     On August 25, 1994, the Company's shareholders approved the Marquette
     Electronics, Inc. Directors' (Non-Employee) Stock Option Plan (the
     "Directors' Plan"). The Directors' Plan is designed to compensate non-
     employee members of the Board of Directors by an annual grant of non-
     qualified options for 4,000 shares of Class A Common Stock at the then fair
     market value of the stock. These options become exercisable in four equal
     annual installments on each of the first four anniversaries of the date of
     grant and expire on the tenth anniversary date. The aggregate number of
     shares that may be issued under the Directors' Plan shall not exceed
     250,000. During fiscal 1994, options to purchase 16,000 shares were granted
     at $14.50 per share. During fiscal 1995, options to purchase 20,000 shares
     were granted at $16.00 per share. During fiscal 1996, options to purchase
     20,000 shares were granted at $16.25 per share. During fiscal 1997, options
     to purchase 16,000 shares were granted at $18.50 per share. All options
     granted were outstanding at April 30, 1997, 32,000 shares of which were
     exercisable.

     The Company adopted SFAS No. 123 "Accounting for Stock-Based Compensation"
     with footnote disclosure. The Company still accounts for all of its stock
     option plans under APB Option No. 25, under which no compensation cost has
     been recognized. Had compensation cost for these plans been determined per
     SFAS No. 123, the Company's net income and earnings per share would have
     been reduced to the following pro forma amounts:

    Pro Forma                      1.22       (1.57)
</TABLE>

     Because the SFAS No. 123 method of accounting does not apply to options
     granted prior to May 1, 1995, the resulting pro forma compensation cost may
     not be representative of that to be expected in future years.

     The weighted average fair value of options granted in fiscal 1997 and
     fiscal 1996 were $8.08 and $8.40, respectively. 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 fiscal 1997 and fiscal 1996, respectively: risk-free rates of
     5.8% and 6.3%, expected dividend yields of zero, expected lives of 7.0
     years and 8.8 years, and expected volatility of 25% and 23% .

(10) Stock Repurchase Agreements-
     By agreement, the Company is obligated to repurchase up to $4,000 worth of
     Class A Common Stock from each of two shareholders, in each case at the
     shareholder's death and at a price per share determined in accordance with
     the agreements. Life insurance with a face value of $6,986 has been secured
     on the lives of the two shareholders to fund the payments required under
     the repurchase agreements. As of April 30, 1997, 397,516 shares of Class A
     Common Stock were subject to these stock repurchase agreements. The amount
     of the purchase price is

<PAGE>
 
     payable within 210 days of the death of the shareholder.

(11) Restructuring of Operations-
     In fiscal 1996, the Company initiated and began to implement a plan to
     restructure its worldwide operations, primarily in Europe. The
     restructuring plan consists of a consolidation of European offices as well
     as a corresponding reduction in the number of employees. The restructuring
     plan is undertaken for purposes of consolidating the distribution function
     in Europe in order to address competitive conditions. In addition, the
     restructuring plan is necessary as the existing Marquette operations are
     integrated with E for M's European operations. In connection with these
     actions, the Company recorded restructuring charges of $3,956 to operating
     expenses in fiscal 1996. These charges include $1,267 of severance costs,
     $1,366 of facility closing costs including asset write-offs, and $1,323 of
     other costs such as dealer termination fees and related legal fees. This
     restructuring plan implementation was completed during fiscal 1997.

(12) Employee Benefit Plans-
     Profit Sharing and 401(k) Plan - The Company has a Profit Sharing and
     401(k) Plan (the "Plan") covering substantially all non-union employees.
     The Plan allows participants to make annual contributions ranging from 1%
     to 12% of their compensation, subject to certain limitations imposed by the
     Internal Revenue Code. The Company matches 30% of the Participants'
     contributions, subject to maximum annual matching per participant of five
     hundred dollars or 1.5% of the participants' qualified compensation,
     whichever is greater. The Company may make annual discretionary
     contributions as authorized by the Board of Directors. Total Company
     contributions were $3,961, $3,313 and $3,300 in fiscal 1997, 1996 and 1995,
     respectively.

     Defined Benefit Plans - Marquette Hellige GmbH has an unfunded
     noncontributory defined pension plan covering substantially all of its
     German-based employees over 25 years of age and with at least 10 years of
     service. The benefits are based on an employee's final month's salary and
     the number of years of continuous service with E for M.

     The Plan was amended in September, 1996 by increasing the retirement age
     for some employees and reducing the pension benefit rate for both new and
     active employees. The impact of the amendment results in an unrecognized
     gain as of April 30, 1997 of $2,084. This will be amortized over the
     remaining service life of active employees which is 14 years.

     The components of net periodic pension cost for the year ended April 30,
     1997 and four month period ended April 30, 1996, respectively, are:

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

Fiscal 1997 compared to Fiscal 1996
<PAGE>
 
Net sales for fiscal 1997 increased by 30.5% to $543.3 million from $416.3
million for fiscal 1996. The Company's patient monitoring, diagnostic cardiology
and supplies and service product lines achieved sales growth of $52.6 million,
$53.9 million and $20.5 million, or 25.3%, 43.3% and 24.5%, respectively. The
fiscal 1997 results include a full year of activity from operations related to E
for M Corporation which was acquired on January 1, 1996. The increase in net
sales is partly attributable to the E for M acquisition. However, all existing
product lines achieved significant growth over last year.

The introduction of new products in both the patient monitoring and diagnostic
cardiology product lines as well as improved distribution have both contributed
to the sales growth. New product introductions at lower price points have
allowed the Company to increase its potential market by adding depth to its
product lines. These lower price point products are important in terms of
increasing the Company's potential market overseas. The increase in net sales
also reflects the effects of a strengthening market for health care equipment in
the U. S. particularly for the patient monitoring product line. The sales growth
for the fiscal year was negatively affected by a softer market in Western
Europe, particularly Germany, France and the United Kingdom, as well the
negative currency conversions due to a stronger U.S. dollar.

Gross profit for fiscal 1997 increased 33.7% to $269.2 million from $201.3
million in fiscal 1996. Gross margin increased to 49.5% for fiscal 1997,
compared to 48.4% for fiscal 1996. The increase relates to manufacturing
efficiencies gained as E for M was fully integrated into Marquette as well as
product mix. The gross margins were negatively impacted by continued pricing
pressures, especially in Europe. However, the mix of higher margin products in
addition to the manufacturing efficiencies offset this negative impact. The
Company expects continued currency fluctuations and European pricing pressures
to affect future gross margins.

Engineering expenses for fiscal 1997 increased 28.9% to $48.1 million from $37.3
million in fiscal 1996. The increase is mainly attributable to the incremental
expenses related to the E for M operations. Engineering expenses as a percentage
of sales decreased slightly to 8.9% for fiscal 1997 from 9.0% for fiscal 1996.
The Company will continue to invest significantly in both new product
developments and continued enhancements to current products. Due to the
competitiveness and technological nature of the medical systems and equipment
industry, this investment is necessary in order to maintain the Company's
competitive position in the health care industry.

Selling expenses for fiscal 1997 increased 31.1% to $138.0 million from $105.3
million for fiscal 1996, due primarily to the E for M acquisition. In addition
to the incremental expenses related to the E for M operations, the expenses for
fiscal 1997 include increased sales bonuses as the Company's bookings for the
year exceeded the bonus thresholds. The increased bookings are reflected in an
increased backlog. These increases in selling expenses were partially offset by
the cost reductions gained through the restructuring of European distribution.
For fiscal 1997, selling expenses increased slightly as a percentage of sales to
25.4% from 25.3% of net sales for fiscal 1996.

General and administrative expenses for fiscal 1997 increased 34.1% to $44.1
million from $32.9 million in fiscal 1996. E for M operations accounted for a
significant portion of the increase. General and administrative expenses as a
percentage of sales were 8.1% for fiscal 1997 as compared to 7.9% for fiscal
1996. A portion of the increase as a percentage of sales relates to the
additional amortization expense for goodwill and other intangibles which were
recorded in connection with the E for M acquisition. During fiscal 1997, $3.5
million of goodwill and intangible amortization were expensed as compared to
$1.2 million of amortization expense related to the E for M acquisition in
fiscal 1996. Exclusive of the increased amortization, general and administrative
expenses as a percentage of sales would have declined from fiscal 1996. The
decline reflects the benefits realized from the restructuring of the European
operations and the E for M operations.

Operating income for fiscal 1997 was $38.9 million as compared to an operating
loss of $13.8 million for fiscal 
<PAGE>
 
1996. The fiscal 1996 operating loss was attributable to a one-time charge
associated with the write-off of purchased research and development in-process
of $35.7 million in connection with the E for M acquisition and to a $4.0
million restructuring charge mainly related to the European operations.
Operating income for fiscal 1996, exclusive of these charges, was $25.9 million.
The increase for fiscal 1997 relates to the increased gross profit attributable
to sales growth and increased margins as well as cost savings associated with
the restructuring.

Interest expense for fiscal 1997 increased to $8.4 million from $4.4 million for
fiscal 1996. The increased interest expense related to the additional debt
outstanding for the entire fiscal year in connection with the E for M
acquisition. In addition, the proceeds received in the public offering of $24.0
million in March, 1997 were used to repay bank term loans incurred in the E for
M acquisition. The Company intends to continue to pay down bank term loans and
foreign lines of credit with any free cash flow in subsequent years. This,
coupled with the reduction in debt associated with the public offering proceeds,
should reduce interest expense in subsequent years.

Other income for fiscal 1997 increased to $3.6 million from $1.2 million in
fiscal 1996. The increase was primarily related to foreign exchange gains of
$1.8 million in fiscal 1997 as compared to $0.6 million in fiscal 1996. The
significant strengthening of the U.S. dollar and the devaluation of the German
mark contributed to the increased exchange gains.

The provision for income taxes for fiscal 1997 was $12.9 million as compared to
$7.9 million in fiscal 1996. The effective tax rate for fiscal 1997 was 37.8%.
In fiscal 1996, the effective tax rate, excluding the impact of the one-time
charge of $35.7 million related to purchased research and development in-
process, was 42.1%. The decrease in the effective rate is attributable to
reduced foreign losses not benefited, the utilization of certain foreign net
operating losses in fiscal 1997, and the reinstatement of the research and
development credit for a significant portion of the fiscal year. The decreases
in the effective rate are offset to some extent by the additional goodwill
expense incurred in connection with the E for M acquisition. Due to the
expiration of the research and development credit in fiscal 1998, management
believes the effective tax rate will increase in fiscal 1998 unless the credit
is reinstated. In addition, the ability to continue to utilize foreign net
operating losses will have an impact on future effective tax rates. If the
European market continues to weaken in the health care industry, unbenefited net
operating losses would increase the Company's effective tax rate.

Fiscal 1996 Compared to Fiscal 1995

Net sales for fiscal 1996 increased 21.7% to $416.3 million from $342.2 million
for fiscal 1995. The fiscal 1996 results included four months of activity from
operations related to E for M. Approximately $54.5 million of the increase in
net sales was due to sales of E for M products. The remaining increase in net
sales for fiscal 1996 of $19.6 million, or 5.7%, was related to the Company's
historic product lines. An improving health care market as well as the E for M
acquisition contributed to an increase in net sales of $27.3 million or 15.1%
for the patient monitoring line and $29.7 million or 31.3% for the diagnostic
cardiology product line. The supplies and service product lines recorded a sales
increase of $17.2 million, or 25.9%, from fiscal 1995. Fiscal 1995 results
included eleven months activity from operations related to Corometrics, which
was acquired in May, 1994.

Gross profit for fiscal 1996 increased 15.0% to $201.3 million from $175.0
million in fiscal 1995. Gross margin decreased to 48.4% for fiscal 1996,
compared to 51.1% for fiscal 1995. The decrease was primarily attributable 
<PAGE>
 
to the lower gross margin realized on E for M products. The gross margin
realized on E for M products for the four months of E for M operations included
in fiscal 1996 was 38.1%. Lower than expected shipment levels of E for M
products, attributable in part to the integration of E for M operations into
Marquette, resulted in an inability to fully absorb fixed costs. All of the
Company's product lines experienced decreases in gross margins, mainly
attributable to increased pricing pressures, especially in Europe. In addition,
the ultrasound imaging line inventory at Corometrics was liquidated at a
significant discount, resulting in a margin decline in that line.

Engineering expenses for fiscal 1996 increased 21.5% to $37.3 million from $30.7
million in fiscal 1995. Most of this increase was related to the acquisition of
E for M, which had $4.9 million of engineering expense for the four months of E
for M operations included in fiscal 1996. The remaining increase was a result of
increased new product development costs, particularly in operating room and
emergency care products. Engineering expenses as a percentage of net sales
remained at 9.0% for fiscal 1996, the same percentage as for fiscal 1995.

Selling expenses for fiscal 1996 increased 23.7% to $105.3 million from $85.1
million for fiscal 1995, due primarily to the E for M acquisition. Of the total
increase, $13.1 million related to the four months of E for M operations
included in fiscal 1996. In addition to the increased expenses related to E for
M, a portion of the increase was also related to the incremental month of
Corometrics expenses included in fiscal 1996 compared to fiscal 1995. The
remaining increase was primarily related to an increased sales staff for all
product lines. For fiscal 1996, selling expenses increased slightly as
percentage of net sales to 25.3%, from 24.9% of net sales for fiscal 1995.

General and administrative expenses for fiscal 1996 increased 29.5% to $32.9
million from $25.4 million in fiscal 1995. General and administrative expenses
increased $6.0 million for fiscal 1996, primarily due to the operations of E for
M. The remaining operations of the Company had an increase of $1.5 million for
fiscal 1996 compared to fiscal 1995. In addition to the increase related to E
for M, an incremental month of Corometrics expenses in fiscal 1996 contributed
to the remaining difference. General and administrative expenses as a percentage
of net sales were 7.9% for fiscal 1996, compared to 7.4% for fiscal 1995.

The Company incurred a restructuring charge of $4.0 million for fiscal 1996,
primarily related to its European operations. The restructuring was undertaken
for purposes of consolidating the distribution function in Europe as well as the
integration of E for M operations into Marquette.

During 1996, the Company took a charge related to the write-off of purchased in-
process research and development ("R&D") in the amount of $35.7 million. This
one-time charge is attributable to the in-process R&D acquired with E for M. The
purchase price of E for M was allocated to the fair value of net tangible and
intangible assets acquired. The portion of the purchase price allocated to the
in-process R&D costs of E for M was written-off resulting in this non-recurring
charge.

Interest expense for fiscal 1996 increased to $4.4 million from $3.0 million for
fiscal 1995. The increased interest expense related to the E for M acquisition
was partially offset by the repayment of $8.0 million of debt originally
incurred in connection with the Corometrics acquisition in May 1994. Cash flow
from operations enabled the Company to retire the remaining debt related to the
Corometrics acquisition during fiscal 1996.

Other income for fiscal 1996 increased to $1.2 million from $0.1 million in
fiscal 1995, primarily due to increased foreign exchange gains of $0.6 million.
In addition, losses related to equity investments were $0.7 million less in
fiscal 1996 as compared to fiscal 1995.

The provision for income taxes for fiscal 1996 was $7.9 million. Even though the
Company incurred
<PAGE>
 
a before-tax loss of $17.0 million for the year, the $35.7 million charge
related to purchased in-process R&D was a permanent tax difference for which the
Company did not receive any tax benefit, either current or deferred. Excluding
this charge, the effective tax rate for fiscal 1996 was 42.1% compared to 37.0%
for fiscal 1995. This increase in the effective tax rate for fiscal 1996 was
partly due to the expiration of the R&D credit (a 1.9% benefit in 1995). This
credit was reinstated prospectively on July 1, 1996. The additional increase in
the tax rate for fiscal 1996 was related to foreign net operating losses which
the Company was unable to utilize.

Financial Outlook

In as much as the Company's principal product lines are all related to the
health care industry, they are subject to the current uncertainty surrounding
the industry including consolidation of hospital groups and a move towards
managed care. While the Company cannot predict the impact, if any, that such
modifications might have on its business, the Company's operating results are
closely linked to the health care economy. If revenue or earnings fail to meet
expectations of the investment community, there could be a significant impact of
the trading price for the Company's stock. Management believes that the
introduction of new products and the partnership relationships being established
with the hospitals will keep the Company in a competitive position as the health
care economy demand for new equipment increases.

Liquidity and Capital Resources

Working capital was $149.2 million at April 30, 1997 as compared to $133.2
million at April 30, 1996. Inventories increased by 4.3% to $110.8 million
primarily due to increased sales levels and to give the Company the continued
ability to effectively manage its backlog. Current liabilities decreased to
$117.6 million at April 30, 1997 from $127.8 million at April 30, 1996 as a
result of the payment of restructuring liabilities from the cash flow from
operations.

As of April 30, 1997, the Company had $8.0 million outstanding on U.S. lines of
credit of $25.0 million. In addition, the Company had $22.4 million, U.S. dollar
equivalent, outstanding on foreign lines of credit. The foreign currency
denominated borrowings are used to reduce the currency risks associated with
foreign currency receivables. As of April 30, 1996, the amounts outstanding on
the U.S. and foreign lines of credit were $14.5 million and $14.3 million,
respectively.

Capital expenditures for fiscal 1997 were $18.2 million as compared to $11.4
million in fiscal 1996. The increase relates primarily to the acquisition of a
new business system offset by the disposal of land in Germany.

The $90.3 million acquisition of E for M was funded by three variable rate bank
term loans each in the amount of $30.0 million. Each bank term loan is payable
in eight equal semi-annual installments of $3.75 million each beginning on April
30, 1997 and continuing on each October 31 and April 30 thereafter through
October 31, 2000. As of April 30, 1997, the Company had repaid or refinanced
$63.0 million of such bank term debt. Cash flow from operations was used to
repay $9.0 million of such debt, cash proceeds in an underwritten public
offering of 1,373,422 shares at a net price of $17.37 were used to repay $24.0
million of the such bank term debt, and the remaining $30.0 million was
converted into longer term fixed-rate senior debt. This senior debt accrues
interest at a fixed rate of 7.46% per annum and matures on August, 29, 2008. The
$27.0 million of bank term debt that remained outstanding as of April 30, 1997
accrued interest at a rate equal to the LIBOR rate plus one percent, reset
monthly. At April 30, 1997, the rate was 6.6875% per annum. The Company intends
to repay the interest and retire the remaining debt through cash flow from
operations.

In October, 1996, the Company repurchased 281,400 shares of Common Stock at a
price of $16.50 per share. The $4.6 million used to repurchase the treasury
stock was funded through cash flow from operations. In December, 1996, 262,500
of the treasury shares were used in the exchange of Class C common
<PAGE>
 
stock for Class A common stock. The Company retained 18,900 shares of treasury
stock as of April 30, 1997.

Management believes the Company has the financial resources to meet its short
term and long term cash requirements. Management believes its cash flow from
operations will be sufficient to continue to fund its current obligations as
well as fund the internal growth of the Company. The current U.S. inflation rate
has little impact on Company operations.

On March 3, 1997, FASB released SFAS No. 128, "Earnings per Share," which
simplifies the standards for computing earnings per share and requires a dual
presentation of basic and diluted earnings per share on the income statement.
This statement will apply to fiscal 1998. However, the impact of the change has
been reported in footnote 2(j).
