ITEM 1.  DESCRIPTION OF BUSINESS.

         OVERVIEW

         Cardiac Science, Inc. ("Cardiac Science" or the "Company") designs, 
develops and intends to market non-invasive automatic external cardiac 
defibrillation ("AECD-Registered Trademark-" devices (the "AECD Products") 
that utilize its proprietary tachyarrhythmia detection and discrimination 
software (the "AECD Technology"). Cardiac Science has been a public company 
since its inception in 1991 when it was "spun-off" from Medstone 
International, Inc. (NASDAQ:MEDS) to its stockholders. From inception up to 
early 1997, the Company primarily was focused on the research and development 
of the AECD Technology and FDA testing of clinical prototypes. In early 1997, 
Cardiac Science employed a new management team and since September 1997 it 
has raised equity capital in the amount of $5.7 million. In addition, through 
its wholly-owned subsidiary, Diagnostic Monitoring, the Company manufactured 
PC-based Holter Electrocardiogram ("ECG") systems and Ambulatory Holter 
recorders and distributed these products in over 40 countries for the period 
of April 1997 through December 31, 1998. On December 31, 1998, the Company 
sold substantially all of the assets of Diagnostic Monitoring to Biosensor 
Corporation (OTC:BSNR).

         Cardiac arrest is the single largest cause of death in the United
States and Europe. It is estimated to strike approximately 1.5 million Americans
yearly and more than double that worldwide, a third of whom die. The number of
persons at temporary risk of life-threatening arrhythmias and cardiac arrest is
significantly higher. Such individuals include hospitalized patients with
symptoms that could indicate a heart attack, heart attack survivors, those
diagnosed with severe forms of heart disease, persons suffering from congestive
heart failure, heart transplant patients and patients whose surgery or treatment
increases the risk of cardiac arrest. The Company's mission is to increase the
survival rate of cardiac arrest victims and create a new standard of care
through the development and commercialization of its proprietary automatic
defibrillation technology.

         The Company received FDA clearance for the AECD Technology in August 
1998. The AECD Technology can be integrated into an external 
defibrillator-monitor or combined with the Company's high-voltage 
defibrillator and related hardware to provide defibrillation therapy without 
the need for human intervention. There are three AECD Products under 
development by Cardiac Science that utilize the AECD Technology. The 
Company's initial product, the Powerheart-Registered Trademark-, is a bedside 
defibrillator-monitor designed for in-hospital use. The Powerheart attaches 
prophylactically to patients for the purpose of providing fully-automatic 
detection and treatment of life threatening tachyarrhythmias (abnormal 
rhythms of the heart), such as ventricular tachycardia (dangerously rapid 
heart rate) and ventricular fibrillation (quivering of the heart), that lead 
to cardiac arrest. It is designed to continuously monitor a patient's cardiac 
activity, detect abnormalities within seconds, and automatically, without 
human interaction, transmit electrical shock (defibrillation) via disposable 
electrodes attached to the patient's chest to convert the patient's heart to 
a normal rhythm.

         The Company received 510(k) clearance from the United States Food and
Drug Administration (the "FDA") in October 1997 on the clinical version of the
Powerheart. To the Company's knowledge, the Powerheart currently is the only
bedside defibrillator-monitor with FDA clearance to provide fully-automated
detection and treatment of ventricular tachyarrhythmias for in-hospital patients
at risk of sudden cardiac arrest. Cardiac Science is working to complete the
development of and begin production of the commercial version of the Powerheart,
the completion of which is anticipated for the second half of 1999. Upon its
completion, of which there can be no assurance, and upon receiving the necessary
regulatory clearances, the Company plans to sell the Powerheart in the United
States and Canada via its strategic partner, Medtronic Physio-Control, and
overseas via a network of qualified international distributors.

        The second AECD Product under development, the RHYTHMx ECD-TM-, is
designed for integration into patient monitoring systems. Functionally, the
RHYTHMx ECD extends patient monitoring systems beyond diagnostics to provide
patients with the added protection of automatic therapy delivery without human
intervention. The Company has designed a conceptual model of the RHYTHMx ECD
which is comprised of the AECD Technology and a high voltage defibrillator
module to be integrated into patient monitoring systems. There can be no
assurance that the Company will be successful in completing the development of
the RHYTHMx ECD.

         The third AECD Product under development is a fully-automatic public
access defibrillator ("PAD") that can be used by first responders and other
non-technical individuals outside of the hospital environment. Cardiac Science
has developed a conceptual model for the PAD and intends to modify the AECD
Technology for this application. The PAD will be designed 

                                      3

<PAGE>

to be small, lightweight, portable, battery-operated and easy to use. There 
can be no assurance that the Company will be successful in completing the 
development of the PAD.

         Cardiac Science has been issued one patent, has one additional patent
under exclusive license and is in the process of filing additional patents
relating to the AECD Technology.

         From May 20, 1991 (inception) through December 31, 1998, the Company
incurred losses of approximately $11 million. Successful completion of the
Company's development program and its transition to attaining profitable
operations is dependent upon achieving a level of revenues adequate to support
the Company's cost structure. The Company currently is seeking financing. There
can be no assurance that the Company will be successful in any of these areas.

         The Company's offices are located at 1176 Main Street, Building "C",
Irvine, California 92614 and the telephone number is (949) 587-0357.

CARDIAC ARREST, LIFE-THREATENING ARRHYTHMIAS AND THEIR TREATMENTS

         Cardiac arrest is the loss of effective pumping action of the heart
caused by life-threatening arrhythmias. It results in the abrupt cessation of
circulation of blood to the brain and other vital organs and, left untreated,
leads to death in a matter of minutes.

         Arrhythmias are caused by disturbances in the electrical conduction
mechanism of the heart, and usually occur in persons suffering from various
forms of heart disease. While not all arrhythmias are life-threatening, the most
common life-threatening arrhythmias are ventricular tachycardia and ventricular
fibrillation. Ventricular tachycardia, in which electrical disturbances cause a
dangerously fast heart rate, is often the precursor to ventricular fibrillation,
which is a rapid, chaotic contraction of the heart that causes the heart to
quiver. In ventricular fibrillation, the electrical activity of the heart is
completely disorganized and ineffectual, producing no pulse or blood pressure.
Ventricular fibrillation can be fatal within minutes unless it is interrupted
and a normal heart rhythm is quickly restored.

         The procedure for terminating life-threatening arrhythmias is known as
defibrillation. Defibrillation is achieved by the application of an electric
shock to the heart, which synchronizes the heart's electrical activity and
causes the normal rhythm of the heart to be restored. Early defibrillation is
the single most important factor in reviving patients in cardiac arrest. In the
case of ventricular fibrillation, there is approximately a 10%-15% decline in a
patient's chance of survival with each passing minute. Defibrillation delayed
much longer than 10 minutes yields a virtual zero probability of survival. The
following graph from the TEXTBOOK OF ADVANCED CARDIAC LIFE SUPPORT, published by
the American Heart Association ("AHA") in 1994, illustrates the percentage
resuscitation rate when defibrillation is administered within the first ten
minutes following the onset of ventricular fibrillation.

         Persons who have survived heart attacks, or who have been diagnosed as
having certain forms of heart disease or who have undergone major heart surgery,
have higher risks of suffering cardiac arrest and sudden death.

                                      4

<PAGE>

         Current modalities for treating life-threatening arrhythmias include
drug therapies, automatic implantable cardioverter defibrillators ("ICDs") which
require surgery, and external cardioverter defibrillators which require human
intervention to analyze and interpret the patient's cardiac activity and/or
administer the shock.

         ICD devices are fully-automatic products and have been clinically 
proven to be the ideal treatment for patients who have been diagnosed as 
being at permanent risk for cardiac arrest. An ICD device is a complex 
electronic instrument, consisting of a heart monitor and defibrillator 
module. It is implanted in the abdominal cavity or chest with electrodes 
attached directly to the heart. When the monitor detects a life-threatening 
arrhythmia that satisfies the detection algorithm criteria designed into the 
device, the defibrillator delivers an electrical charge into the heart that 
provides nearly instantaneous reversion to normal heart rhythm.

     Non-surgical external defibrillators are widely used to treat patients in
cardiac arrest. One type of device is the manual defibrillator, for which a
highly skilled human operator (i.e., a physician or paramedic) must analyze and
interpret the patient's electrocardiogram (ECG) data to determine if
defibrillation is required and, if necessary, manually administer an electrical
shock. Recently, more sophisticated automated external defibrillators (AEDs)
have been developed which perform the analysis of the patient's heart rhythm
and, if it is determined that the patient is in cardiac arrest, advise the
operator to administer the shock. The common denominator among these existing
devices is that they require the presence of a human operator (frequently a
skilled one) to administer the shock. The time interval from cardiac arrest to
the moment a shock is delivered is typically several minutes.

     Clinical studies have shown that the average survival rate of patients who
have had an in-hospital cardiac arrest is about 15 percent and has not improved
since the 1960s. The AHA has acknowledged that it has under-emphasized the role
of prompt defibrillation. The AHA, as well as the world's major resuscitation
councils, have determined that rapid defibrillation is the single most important
therapy for the treatment of cardiac arrest. Studies have documented delays of
more than 5 minutes between recognition of cardiac arrest and first
defibrillation. Immediate defibrillation means significantly increased survival
rates, reduced damage to heart and other vital organs, including the brain,
which may lessen debilitation and quicken recovery periods. Clinical studies
have shown survival rates of 90 percent when cardiac arrest patients are
defibrillated in less than one minute. For each minute that passes after cardiac
arrest, the likelihood of survival decreases approximately 10-15 percent.
Accordingly, early rhythm assessment and rapid defibrillation can significantly
improve survival rates.

THE COMPANY'S AECD PRODUCTS UNDER DEVELOPMENT

         GENERAL

         The Company has developed proprietary detection and discrimination
software (the "AECD Technology") which can be integrated into an external
defibrillator-monitor or combined with the Company's high-voltage defibrillator
and related hardware to provide defibrillation therapy without the need for
human intervention. The AECD Technology is designed for devices that are
non-invasive and do not require surgery. In accordance with patient specific
parameters programmed into a device's microcomputer by the patient's physician,
the AECD Technology will enable such device to continuously monitor a patient's
cardiac activity, detect life-threatening abnormalities, and, within less than
30 seconds and without human interaction, transmit an electrical defibrillation
shock to convert the patient's heart to a normal rhythm. The Company received
FDA clearance for its AECD Technology in August 1998.

    MULTIPLE PRODUCTS FROM CORE TECHNOLOGY

         There are three AECD Products under development by Cardiac Science
which utilize the AECD Technology. The Company's initial product, the
Powerheart, is a defibrillator-monitor designed for in-hospital use. The Company
received 510(k) clearance on the clinical version of the Powerheart in late
1997. The second AECD Product under development, the RHYTHMx ECD, is designed
for integration into patient monitoring systems. The third AECD Product under
development is a fully-automatic public access defibrillator that can be used by
first responders and other non-technical individuals outside of the hospital
environment.

   THE POWERHEART AECD HOSPITAL BEDSIDE DEFIBRILLATOR-MONITOR

         The Powerheart is a fully automatic bedside defibrillator-monitor
designed for in-hospital use that can detect cardiac arrest within seconds
without the need for observation by a nurse or physician. When appropriate, a
defibrillation shock is automatically delivered in seconds without human
intervention, as compared to the current approach to in-hospital cardiac arrest

                                      5

<PAGE>

which has inherent delays and can take several minutes before a 
defibrillation shock is delivered. Currently, a life-threatening event must 
be detected and observed and the defibrillator must be moved to the patient 
and connected prior to the actual shock being delivered by highly trained 
hospital personnel.

         The commercial version of the Powerheart which is currently under
development is designed for wall mounting or for use as a transport monitor. It
is also designed to be transported by mobile "pole cart" or carried by hand.
Cardiac Science believes the Powerheart will offer significant advantages over
defibrillators currently used in hospitals today and will be ideally suited for
use in many areas of the hospital, including the Operating Room (OR), the
Intensive Care Unit (ICU), the Cardiac Care Unit (CCU), the Emergency Room (ER),
the Step-Down Unit (SDU), the Recovery Room (RR), the Catheterization Lab
(CATH), Transport (EMS), and the Free-Standing Surgery Center (FSC).

     POWERHEART DESIGN AND TECHNOLOGY

     The Powerheart includes the following basic components:

- -    TACHYARRHYTHMIA DETECTION AND RHYTHM ANALYSIS SOFTWARE AND HARDWARE 
     SYSTEM - The AECD Technology is integrated with the necessary hardware 
     components to access the patient's electrocardiogram signal to determine 
     when therapy is appropriate based upon parameters set by the patient's 
     physician. ECG signals are sensed by disposable defibrillator pads placed 
     on the patient's chest. This signal is amplified and filtered by an 
     electrical analog circuit, digitized, and then analyzed by the device's 
     proprietary software algorithms, which makes the determination of when 
     and if therapy (a defibrillation shock) is appropriate for the patient.

- -    DEFIBRILLATOR - The Powerheart uses electrical circuitry that provides an
     Association for the Advancement of Medical Instrumentation ("AAMI")
     standard waveform for defibrillation. Such waveforms are used by a majority
     of defibrillators on the market, and have the longest proven record of
     success. The Powerheart can be programmed to transmit low amounts of
     electrical energy to the heart to terminate life-threatening arrhythmias.
     The Powerheart is designed to provide progressively greater amounts of
     energy, if needed, to restore the patient's heart to its normal cardiac
     rhythm. The maximum energy that can be delivered by the device is 360
     joules, which is the maximum limit recommended by the American Heart
     Association.

- -    DEFIBRILLATION ELECTRODES - The Powerheart uses self-adhesive, disposable
     defibrillation electrodes manufactured by a third party vendor to the
     Company's specifications. Electrodes require daily replacement.

- -    DATA STORAGE - The device stores ECG data on a real-time basis in digital
     form. In addition, a strip chart recorder automatically prints real-time
     ECG and relevant parameter settings.

- -    GRAPHICAL USER INTERFACE - Operating modes and setting parameters for
     rhythm analysis are programmed via the user interface. It has a liquid
     crystal display that displays real-time patient ECG, device actions and
     device settings.

- -    DATA RETRIEVAL SOFTWARE - This software is used to access the data stored
     from the Powerheart. This software runs on a personal computer. The data
     can be viewed on a monitor and printed on a standard high-resolution
     printer. This provides valuable post-facto analysis of the patient's rhythm
     and device operation.

     RHYTHMx ECD PATIENT MONITORING MODULE

         The RHYTHMx ECD module, which is currently under development, is being
designed for integration into patient monitoring systems. The Company has
designed a conceptual model of the RHYTHMx ECD which includes AECD Technology
and a high voltage defibrillator module to be integrated into patient monitoring
systems. Functionally, the RHYTHMx ECD extends patient monitoring systems beyond
diagnostics to automatic therapy delivery without human intervention. The
RHYTHMx ECD will enable a patient monitoring system to accurately and instantly
detect the onset of ventricular tachyarrythmias, discriminate between a
shockable and nonshockable rhythm, and direct a high voltage defibrillator
module to automatically deliver a therapeutic shock without the need for human
intervention. This therapeutic shock will convert a patient's heart rhythm back
to normal within seconds from the onset of the event. The Company believes the
RHYTHMx ECD will add life saving cardioversion/defibrillation capabilities to
the patient monitoring system.

                                      6

<PAGE>

    THE COMPANY BELIEVES, ALTHOUGH THERE CAN BE NO ASSURANCE IN THIS
REGARD, PATIENT MONITORING SYSTEMS INCORPORATING THE RHYTHMX ECD CAN PROVIDE
NUMEROUS BENEFITS:

- -    Sudden cardiac arrest survival rates can be dramatically improved 
- -    Earlier intervention may lower complications associated with long 
     resuscitation times
- -    Faster defibrillation will eliminate damage to brain and other vital organs
- -    Patients can be stepped down to lower acuity (i.e. less expensive)
     settings faster 
- -    Reduced complications equal lower cost to patient and healthcare system 
     A new capability with a very low cost per patient bed

     PUBLIC ACCESS DEFIBRILLATOR (AED)

         Individuals experiencing cardiac arrest need immediate defibrillation
wherever the episode occurs. Short of having an AECD Product attached to them,
the best public alternative is to have one immediately available. This is the
concept behind the automated external defibrillator (AED) or public access
defibrillator (PAD). Since 1994, the AHA has focused on early defibrillation and
has urged making PADs widely accessible. The market for PADs includes the first
responders (i.e., EMTs, fire trucks, police cars), the clinical segment (i.e.,
out patient clinics, doctors and dentists offices), the industrial segment
(i.e., stadiums, commercial airlines, office buildings, retirement homes, health
clubs and golf courses), and other markets (i.e., home, military and places the
public gathers).

         Cardiac Science has developed a conceptual model and intends to design
its PAD to be small, lightweight, portable, battery-operated and easy-to-use. In
addition, it is anticipated that it will offer Cardiac Science's AECD Technology
and the more traditional semi-automatic rhythm analysis, feature a
state-of-the-art optimized low energy defibrillator waveform, voice prompts to
assist users, and disposable defibrillator pads, data recording, storage &
retrieval as well as self-test capabilities. 

RESEARCH, DEVELOPMENT AND FDA CLINICAL EVALUATION

         Research and development expenditures were $2,209,524 in 1998 and
$756,936 in 1997. Expenditures in 1998 primarily were attributable to the costs
associated with the development of the commercial version of the Powerheart.

   FDA CLINICAL EVALUATION

         To test the safety and efficacy of the AECD Technology, a multi-center
clinical trial study was conducted from 1993 to 1997. The trial was divided into
two phases. Phase I tested the tachyarrhythmia detection and discrimination
algorithm. Phase II tested the entire system including both the algorithm and
the shock delivery system. In the Phase II trial, patients attached to the
clinical prototype of the Powerheart defibrillator-monitor were studied in
either the electrophysiology laboratory or in critical care units.

         Phase II data was collected from a total of 155 patients at Arizona
Heart Institute, University of California-Irvine Medical Center and USC Medical
Center for over 1200 hours during this study. The study found that the AECD
Technology had a sensitivity of 100% (correctly identifying shockable episodes),
and a specificity of 99.4 percent (not allowing a non-shockable rhythm to be
shocked). The average response time was approximately 21 seconds. In addition,
normal rhythm was restored by the first shock in 96% of the actual shocks
delivered with energy levels as low as 50 joules.

         In late February 1997 the Company submitted a 510(k) pre-market
notification to the FDA, pursuant to Section 510(k) of the Federal Food, Drug
and Cosmetic Act, for the clinical version of the Powerheart
defibrillator-monitor for in-hospital use. 510(k) clearance was received from
the FDA in October 1997.

         In August 1998, the Company received Section 510(k) clearance from the
FDA for its AECD Technology and to integrate it into bedside
monitor-defibrillator platforms. The Company believes that the integration of
the AECD Technology into external defibrillators and patient monitors widely
used in hospitals has the potential to save thousands of lives annually. To the
Company's knowledge, the AECD Technology is the first and only software cleared
by the FDA to provide fully-automatic detection and treatment of
life-threatening heart rhythms.

MARKETING AND SALES

         MARKET OVERVIEW

                                      7

<PAGE>

         The Powerheart bedside defibrillator-monitor and RHYTHMx ECD module
target a large hospital market of over 10,000 hospital locations around the
world. Patients spend nearly 1.0 million days annually in U.S. hospitals with
ventricular fibrillation, ventricular tachycardia or cardiac arrest as the
primary diagnosis. Another 1.4 million days are spent with unspecified cardiac
arrhythmia, premature beats, conduction disease such as sick sinus syndrome, and
functional disorders as the principal diagnosis. The number of persons at least
temporarily at risk of life-threatening arrhythmias and cardiac arrest includes
hospitalized patients with symptoms that could indicate a heart attack, heart
attack survivors, those diagnosed with severe forms of heart disease, persons
suffering from congestive heart failure, heart transplant patients, and patients
whose surgery or treatment increases the risk of cardiac arrest.

         The Company believes that the key to adoption of its AECD Products will
be market awareness of, and exposure to, the devices, as well as clinical
experience with the AECD Products. The Company believes that the commercial
success of its initial product, the Powerheart, will require active marketing,
education and sales efforts to bring market awareness to the product. The
Company believes that decisions to purchase the AECD Products generally will be
made by cardiologists, cardiovascular specialists (including those specializing
in electrophysiology and arrhythmia control), internists, nursing staffs,
administrators and other hospital personnel involved in product procurement and
cost benefit analysis.

         MARKETING STRATEGY

         POWERHEART

         Cardiac Science's strategy is to focus on accelerating the market
adoption and penetration of the Powerheart via its strategic partner, Medtronic
Physio-Control, in the United States and Canada, and via a network of qualified
international distributors overseas.

         In December 1998, Cardiac Science entered into a five-year exclusive 
distribution and licensing agreement with Medtronic Physio-Control, a 
subsidiary of Medtronic Inc., (NYSE: MDT). Medtronic Physio-Control is the 
world market leader in external defibrillation. Under the agreement, 
Medtronic Physio-Control will market the Powerheart on an exclusive basis in 
the United States and Canada. Medtronic Physio-Control also obtained a 
license to the AECD Technology for integration into their in-hospital
LIFEPAK-Registered Trademark- defibrillator-monitor products. This license is 
non-exclusive outside of the United States. The agreement also provides for 
Cardiac Science to share profits from the sale of proprietary disposable 
defibrillator pads that are used with the Powerheart as well as 
Physio-Control LIFEPAK defibrillators that include the AECD Technology 
("Software Technology Packages"). Exclusivity is conditioned upon Medtronic 
Physio-Control purchasing an aggregate of 14,000 Powerhearts or Software 
Technology Packages over the five-year term. The first year's minimum is 
1,000 units. Cardiac Science has retained the right to sell the AECD 
Technology in any market or embed it in any products other than "stand-alone" 
defibrillator-monitors.

         Pursuant to the agreement, Medtronic Physio-Control was granted
warrants to purchase 200,000 shares of Cardiac Science common stock, par value
$0.001 per share (the "Common Stock"), at $3.00 per share. These warrants will
expire in November 1999. Medtronic Physio-Control also will receive warrants to
purchase an additional 200,000 shares of Common Stock upon the sale of the
1,000th unit by Medtronic Physio-Control.

         The Company plans to penetrate the international market by establishing
a network of qualified international distributors managed by Company employees
on a country-by-country basis. As of January 1999, the Company has received
interest from hundreds of distributors interested in marketing the Powerheart in
their respective markets. Cardiac Science anticipates signing agreements with
approximately 45 of these companies in 1999, however there can be no assurance
in this regard.

         RHYTHMx ECD

         The Company's believes the RHYTHMx ECD module will easily interface
with patient monitoring systems. Although there is no assurance that the Company
will succeed in its efforts, Cardiac Science plans to accommodate patient
monitoring and defibrillator manufacturers by licensing its patented
technologies to those who see the benefit of offering the new AECD capability.
The Company currently has no agreements with respect thereto but has received
interest from, and believes it can establish OEM partnerships with,
well-established domestic and foreign patient monitoring manufacturers. Once
strategic partnerships are established, Cardiac Science will work with its
partners to integrate and embed its AECD Technology into their multiparameter
patient monitoring systems. As a result of this strategy, Cardiac Science hopes
to quickly penetrate the market and gain measurable license revenue and sell a
significant number of disposable defibrillator pads.

         THE AMBULATORY ECG (HOLTER) PRODUCTS OF THE DIAGNOSTIC MONITORING
         SUBSIDIARY

         In April 1997, the Company acquired Innovative Physician Services,
Inc., d/b/a Diagnostic Monitoring ("DM"), a Nevada corporation. On December 31,
1998, the Company sold substantially all of the assets of DM to Biosensor
Corporation (OTC:BSNR) for 1,440,000 shares of Biosensor Corporation common
stock representing 7.7 percent of the voting shares.

         During the period from April 1997 to December 1998, DM generated 
revenues of $2,650,570 from the sale of its PC-based Ambulatory Holter ECG, 
Holter recorders and related supplies and accessories. Sales were made 
through qualified domestic and international distributors in over 40 
countries. For the year ended December 31, 1998, sales of DM's 
Windows 95-Registered Trademark- compatible Holter software and systems, Holter
Recorder products, and related Holter supplies represented 79% of the DM's 
total revenue, sales of PC-based Electrocardiographs accounted for 4% of 
revenues, sales of Spirometers accounted for 4% of revenues and Ambulatory 
Blood Pressure products accounted for 6% of revenues. Export sales of DM's 
products to international countries represented 85% of the Company's revenue, 
with the balance of sales coming from within the United States. The Company 
has restated its prior financial statements to present the operating results 
of DM as a discontinued operation (see note 5 of the consolidated financial 
statements).

MANUFACTURING

         To date, the Company's AECD manufacturing activities have been limited
to the production of prototypes of its Powerheart for use in its clinical
trials. In September 1998, the Company entered into a development and
manufacturing agreement with ZEVEX, Inc. ("Zevex"), a contract medical device
manufacturer. Although there can be no assurance, commercial production of the
Powerheart is anticipated to begin in the second half of 1999.

         The Company currently contemplates that the materials to be used in
manufacturing the Powerheart will consist primarily of electronic, mechanical
and electromechanical components that generally are available from various
vendors and suppliers. However, certain components require customization for the
Company by selected vendors and their availability cannot be assured. The
Company intends to warehouse sufficient components to meet its monthly
production needs and to carry an inventory of finished goods adequate to meet
its customers needs. As of December 31, 1998, the Company did not have any
backlog in orders for its AECD Products.

         The FDA and foreign counterparts will conduct periodic inspections of
such facilities and manufacturing so as to ensure compliance with Quality System
and Good Manufacturing Practices and other regulations, such as those
promulgated by the International Standards Organization, and any concerns raised
by such inspections could result in regulatory action, delays, or termination of
production.

COMPETITION

         To the Company's knowledge, its Powerheart is the only external
defibrillator device with 510(k) clearance to provide fully-automated detection
and treatment of ventricular tachyarrhythmias for in-hospital patients at risk
of sudden cardiac arrest. The Powerheart may compete with a variety of
semi-automatic and manual defibrillators presently in use which are developed by
Medtronic Physio-Control, Hewlett Packard Corporation and Zoll Medical, Inc.,
designed to deliver therapy after being activated by a trained medical
technician responding to a cardiac emergency. The Company also may compete with
products from other companies, such as Heartstream, Inc. (now a division of
Hewlett Packard), SurVivaLink, Inc., and Laerdal Corporation, which may be used
by first responders and lay persons. All of the foregoing products, unlike the
Powerheart, require human intervention.

         The Company believes its AECD Products will not compete with ICD
devices. The Company's AECD Products may be utilized by patients waiting for ICD
implant surgery or patients temporarily unable to risk such surgery.

         Many of the Company's competitors are well established in the medical
device field and have much greater financial, research, manufacturing and
marketing resources than the Company. There is no assurance that such companies
or other competitors will not develop invasive or non-invasive products capable
of delivering the same or greater therapeutic benefits as the products of the
Company. Further, there is no assurance that future forms of technology or
therapies for treating cardiac arrest will not render the Company's products
obsolete or uneconomical.

PATENTS, TRADEMARKS AND PROPRIETARY RIGHTS

         The Company believes that patent and trademark protection is valuable
to the Company as a barrier to market entry by others. The Company also believes
that its trade secrets, proprietary technology, early market entry and its
ability to develop a market for its AECD Products may be equally important.
However, there is no assurance that the Company's technology will not be copied
or duplicated by competitors.

         On December 12, 1995, the U.S. Patent and Trademark Office issued to
the Company Patent No. 5,474,574 titled "Automatic External Cardioverter
Defibrillator". The inventors have assigned to the Company the rights under the
patent on a royalty-free basis. However, no assurances can be given that this
patent will be upheld if challenged, or that this patent will provide an
effective barrier to entry by other entities.

         In December 1993, the Company obtained an exclusive license under
United States Patent No. 4,576,170, issued on March 18, 1986 and titled "Heart
Monitor and Defibrillator Device," to make, have made, use and sell products
covered by the patent. The Company believes that this patent relates to one or
more of the AECD Products. The Company is required to pay royalties, including
minimum annual royalties ($0 for the first year, $10,000 for the second year and
$20,000 per year thereafter until expiration of the Patent), based upon sales of
products covered by the patent. No assurance can be given that this patent would
be upheld if challenged, or that this patent will provide an effective barrier
to entry by other entities.

         The United States Patent and Trademark Office has granted the Company a
registration of the "AECD", "POWERHEART" and "MDF" marks. The Company has filed
a trademark application with the United States Patent and Trademark Office for
the "AECD ELECTRODES" mark. Additionally, Great Britain, France, Japan and China
have granted the Company registration of the "AECD", "AECD ELECTRODES" and
"POWERHEART" marks. Applications are pending in certain other foreign countries
for the registration of these marks. There can be no assurance that any other
trademarks will be granted to the Company, or that any of the Company's
trademarks would be sustained in court if interfered with or challenged.

         In 1992, the Company was assigned all of the right, title and interest
to any and all trade secret rights and technology concerning the manufacture of
defibrillator devices for the treatment of ventricular tachyarrhythmias such as
ventricular tachycardia, ventricular fibrillation and similar heart diseases,
held by Medstone International, Inc., a principal stockholder of the Company,
but excluding any such rights and technology to the extent they have been used
in the past or are presently being used in the manufacture of Medstone's
lithotripsy products, which are used for the non-invasive disintegration of
kidney stones in human patients.

         Other patents in the field of the Company's technology are known to
exist. Although the Company does not believe that licenses are necessary under
the other patents of which the Company is aware, no assurances can be given that
the Company's technology will not be challenged as infringing upon the other
patents. Also, no assurances can be given that the Company's technology will not
be challenged as infringing upon other patents or proprietary rights of others
in the United States or worldwide of which the Company is not aware.

GOVERNMENTAL REGULATIONS

         Clinical testing, manufacturing, packaging, labeling, promotion,
marketing, distribution, registration, listing, notification, recordkeeping,
reporting, clearance and approval of medical devices such as the AECD Products
in the United States generally are subject to regulation by the FDA. Medical
devices intended for human use are classified into three categories, subject to
varying degrees of regulatory control. Class III devices, which include the AECD
Products, are subject to the most stringent controls.

         Class III devices, in general, may be commercially marketed only after
the grant of a Premarket Approval ("PMA"). The PMA process generally takes
several years and substantial financial resources to accomplish. Some Class III
devices may be marketed based upon the submission of a 510(k) Notification to
the FDA where the FDA does not require a PMA and the device is "substantially
equivalent" to a similar product which was commercially marketed in the United
States prior to May 28, 1976.

         In October 1997 the Company received 510(k) clearance from the FDA to
market its Powerheart in the United States. The AECD Products will be subject to
FDA review of labeling, advertising and promotional materials, as well as record
keeping and reporting requirements. Failure to comply with any of the FDA's
requirements, or the discovery of a problem 

                                      10

<PAGE>

with any of the AECD Products, could result in FDA regulatory or enforcement 
action. Further, any changes to the AECD Products or their labeling may 
require additional FDA testing, review and approval.

         Any financial interests in the Company held by investigators could also
be subject to future regulation. Congress recently enacted legislation providing
that the Department of Health and Human Services promulgate regulations defining
the circumstances that constitute financial interest in a project that may
create a bias for certain results. Such rules may require disclosure of, limit
or prohibit equity ownership by, individuals conducting research for the
Company.

YEAR 2000 ISSUE

         In the next twelve months, many companies will face a potentially
serious information systems (computer) problem because many software
applications and operational programs written in the past may not properly
recognize calendar dates beginning in the Year 2000. This problem could force
computers to either shut down or provide incorrect information and could result
in an inability to process transactions or engage in normal business activities.
Based on a recent assessment, the Company believes that the software utilized by
the Company will not be impacted by the Year 2000 Issue. The Company believes
that its existing information systems equipment, primarily composed of personal
computers, will be minimally impacted by the Year 2000 Issue, as the Company
intends to replace those systems which may be affected by this problem by the
end of 1999 due to technological obsolescence. In addition, the Company's
initial products, the Powerheart, and its AECD Technology are not expected to
encounter any problems with the Year 2000 issue. The Company has initiated
communications with its vendors regarding the Year 2000 Issue. Costs spent to
date on the Year 2000 issue are minimal and the Company does not expect to incur
additional costs which would be considered material. If the Company determines a
particular vendor will be impacted by this problem, the Company may attempt to
identify additional or replacement vendors, which could delay accessibility of
the products and/or services provided by such vendors. Such a delay or failure
to identify an additional or replacement vendor could have a material adverse
effect on the Company's business, operating results and financial condition.

EMPLOYEES

         The Company currently has 24 employees including 12 in research and
development, three in the regulatory and quality assurance department, five in
sales and marketing and four in administration which include Raymond W. Cohen,
President and CEO and Brett L. Scott, the CFO and Secretary.

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

GENERAL

         The following discussion should be read in conjunction with the
consolidated financial statements of the Company and notes thereto set forth
elsewhere herein.

         The Company is engaged in the development of non-invasive
fully-automatic external defibrillation ("AECD") devices (the "AECD Products")
for the treatment of arrhythmias that lead to cardiac arrest. The Company
commenced operations in May 1991. Until its acquisition of Diagnostic Monitoring
in April 1997, its operations have consisted primarily of research and
development activities and clinical FDA testing. Diagnostic Monitoring
manufactured PC-based Holter Electrocardiogram ("ECG") systems and Ambulatory
Holter recorders and distributed these products in over 40 countries. The
Company sold substantially all of the assets of Diagnostic Monitoring on
December 31, 1998 (see note 5 of the consolidated financial statements).

         Cardiac arrest is the single largest cause of death in the United
States and Europe. The Company's mission is to increase the survival rate of
cardiac arrest victims and create a new standard of care through the development
and commercialization of its proprietary automatic defibrillation technology
(the "AECD Technology").

         There are three AECD Products under development by Cardiac Science that
utilize the AECD Technology. The Company's initial product, the Powerheart, is a
bedside defibrillator-monitor designed for in-hospital use. The Powerheart
attaches prophylactically to patients for the purpose of providing
fully-automatic detection and treatment of life-threatening tachyarrhythmias
(abnormal rhythms of the heart), such as ventricular tachycardia (dangerously
rapid heart rate) and ventricular fibrillation (quivering of the heart), that
lead to cardiac arrest. The second AECD Product under development, the RHYTHMx
ECD module, is designed for integration into patient monitoring systems.
Functionally, the RHYTHMx ECD module extends patient monitoring systems beyond
diagnostics to provide patients with the added protection of automatic therapy
delivery without human intervention. The third AECD Product under development is
a fully-automatic public access defibrillator ("PAD") that can be used by first
responders and other non-technical individuals outside of the hospital
environment.

         The Company believes the AECD Products are ideally suited for
hospitalized and non-hospitalized patients temporarily at risk (periods ranging
from days to months) of suffering cardiac arrest. Through its investment in
clinical research, the Company believes it has established competitive
functional and technological advantages in the development of AECD devices. The
Company has been issued one patent, has one additional patent under exclusive
license and is in the process of filing additional patents relating to its AECD
technology.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

         Expenses for research and development increased to $2,209,524 for the
year ended December 31, 1998 compared to $756,936 for the year ended December
31, 1997. This increase was due to engineering and pre-production costs
associated with the commercialization of the Company's initial AECD product, the
Powerheart. Included in these costs were increases in personnel costs and
related fringes, and payments to independent engineering contractors and Zevex,
Inc., the Company's contract manufacturer.

         Marketing expenses increased to $341,476 for the year ended December
31, 1998, compared to $251,777 for the year ended December 31, 1997. The
increase was a result of pre-marketing expenses related to the Powerheart and
the addition of personnel and related fringes.

         General and administrative expenses increased to $1,170,551 for the
year ended December 31, 1998, compared to $766,991 for the year ended December
31, 1997. The increase was a result of expenditures incurred to support the
infrastructure necessary to commercialize the Powerheart and begin initial
preparations for market release. Expenses, which increased in 1998 as compared
to 1997, include personnel costs and related fringes, insurance premiums for
both product liability and directors and officers insurance, and professional
fees.

         Net interest expense increased to $65,353 for the year ended December
31, 1998 as compared to $10,133 for the year ended December 31, 1997. The
increase was associated with the debt incurred as a result of the acquisition of
Diagnostic Monitoring, borrowings on the bank line of credit in 1998 and the
debt discount in connection with the issuance of warrants (see note 10 to the
consolidated financial statements).

         Interest income was approximately the same at $6,470 for the year ended
December 31, 1998 as compared to $5,886 for the year ended December 31, 1997.

         For the year ended December 31, 1998, the Company incurred a net loss
from continuing operations of $3,787,704, as compared to $1,780,751 for the year
ended December 31, 1997. The increased loss for the year ended December 31, 1998
primarily is attributable to the increases in operating expenses, which included
expenses incurred in the process of commercializing the Powerheart.

         On December 31, 1998 the Company sold substantially all of the assets
of Diagnostic Monitoring ("DM"). The Company has restated its prior financial
statements to present the operating results of DM as a discontinued operation
(see note 5 of the consolidated financial statements). For the year ended
December 31, 1998, the Company incurred a net loss from discontinued operations
of $101,412 as compared to $43,847 for the year ended December 31, 1997. The
Company also recognized a loss on the sale of DM's assets of $549,618. This
non-cash loss primarily was attributable to the write off of goodwill associated
with the original purchase of DM.

INCOME TAXES

         The Company has approximately $10,110,000 of federal net operating loss
carryforwards and $2,875,000 of California net operating loss carryforwards at
December 31, 1998 which will begin to expire in 2007 and 1999; respectively. The
Company had deferred tax assets of $4,181,335 at December 31, 1998. The Company
has established a valuation allowance to fully offset its deferred tax assets.

LIQUIDITY AND CAPITAL RESOURCES

         At December 31, 1998, the Company had cash and cash equivalents and a
working capital deficit of $1,247,602 and $(549,898), respectively. From
inception, the Company's sources of funding for operations were derived from
equity placements aggregating approximately $11,200,000. The Company has
incurred losses of approximately $11 million since inception and expects to
incur substantial additional operating losses as a result of expenditures
related to the marketing and sales support functions, research and product
development activities and the completion and initiation of clinical trials for
future products. The timing and amounts of these expenditures will depend upon
many factors, some of which are beyond the Company's control, such as the
results of clinical trials, the requirements for and time required to obtain
approval of 510(k) applications or other regulatory approvals, the progress of
the Company's research and development programs, and market 

                                      14

acceptance of the Company's products.

         Additional capital will be needed to fulfill the Company's marketing,
research and product development goals. Successful completion of the Company's
development program for its AECD Products and its transition to attain
profitable operations is dependent upon achieving a level of revenues adequate
to support the Company's cost structure.

         The Company raised $3,700,000 in a series of private placements during
the year ended December 31, 1998. In connection with these private placements
the Company paid certain fees and expenses. The Company also arranged for a
short term non-interest bridge loan of $100,000 in September 1998 that was
repaid in January 1999. In consideration for this loan the lender received
three-year warrants to purchase 50,000 shares of Common Stock at a per share
price of $2.00.

         In 1998 the Company had net borrowings of $125,000 on a revolving line
of credit from a bank. The line of credit expired in November 1998 and was
restructured as a twelve-month term loan with monthly payments of $10,417 plus
interest beginning in January 1999.

         The Company anticipates that its current cash balance will be 
sufficient to meet the Company's cash requirements through the first calendar 
quarter of 1999. Given the current applications of cash, the Company expects 
that further capital additions will be necessary to sustain growth and 
viability. In this respect, the Company is considering a number of 
alternatives, including additional equity financings and corporate 
partnerships. There can be no assurance that any such transactions will be 
available at terms acceptable to the Company or that any financing 
transaction will not be dilutive to current stockholders or that the Company 
will have sufficient working capital to fund future operations. If the 
Company is not able to raise additional funds, it may be required to 
significantly curtail or cease its operating activities. The accompanying 
financial statements have been prepared assuming that the Company will 
continue as a going concern. Accordingly, the independent accountant's report 
on the Company's financial statements has an explanatory paragraph addressing 
the Company's ability to continue as a going concern.

                        REPORT OF INDEPENDENT ACCOUNTANTS



The Board of Directors and Stockholders
Cardiac Science, Inc.
Irvine, California

In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, stockholders' deficit, and cash flows
present fairly, in all material respects, the financial position of Cardiac
Science, Inc. (the "Company") at December 31, 1998, and the results of its
operations and its cash flows for the years ended December 31, 1998 and 1997, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

The accompanying financial statements have been prepared assuming that the 
Company will continue as a going concern. As discussed in Note 2, the Company 
has suffered recurring losses from operations which raises substantial doubt 
about the Company's ability to continue as a going concern. Management's plans 
with regard to this matter are also described in Note 2. The financial 
statements do not include any adjustments that might result from the outcome of
this uncertainty.

                              CARDIAC SCIENCE, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1.       ORGANIZATION AND CAPITALIZATION OF THE COMPANY

         Cardiac Science, Inc. (the "Company") was incorporated on May 20, 1991
to develop, manufacture and market software driven non-invasive (non-surgical)
Automatic External Cardioverter Defibrillator ("AECD") devices (the "Products")
to treat persons suffering from or at high risk of life-threatening arrhythmias.
The Products, all of which are still under development, are designed to
continuously monitor, quickly detect and then automatically, through
transmission of electrical energy charges to the patient's heart, terminate the
ventricular tachyarrhythmia (dangerously fast heart rate) and/or ventricular
fibrillation (quivering of the heart following tachyarrhythmia, which usually
results in death).

         On April 11, 1997, the Company acquired Innovative Physician Services,
Inc. (d.b.a. Diagnostic Monitoring) ("DM") for 500 shares of the Company's
Series A Convertible Preferred Stock (the "Preferred Stock") plus a non-interest
bearing promissory note in the principal amount of $100,000 that was repaid
during 1998. On September 8, 1997, the Company effectuated a one-for-11.42857413
reverse stock split and the shares of Preferred Stock automatically converted
into 500,000 shares of common stock. All share and per share amounts have been
adjusted to give retroactive effect to the Reverse Split for all periods
presented. The Company sold substantially all of the assets of Diagnostic
Monitoring on December 31, 1998 (see notes 4 and 5).

2.       CONTINUED EXISTENCE

         Additional capital is needed to fulfill the Company's marketing,
research and product development goals. Through December 31, 1998, the Company
incurred losses of approximately $11 million. Recovery of the Company's assets
is dependent upon future events, the outcome of which is indeterminable.
Additionally, successful completion of the Company's development program and its
transition to attain profitable operations is dependent upon achieving a level
of revenues adequate to support the Company's cost structure. The Company
anticipates that its current cash balance will be sufficient to meet the
Company's cash requirements for at least the next three (3) months. Given the
current applications of cash, the Company expects that further capital additions
will be necessary to sustain growth and viability. In this respect, the Company
is considering a number of alternatives, including additional equity financings
and corporate partnerships. There can be no assurance that any such transactions
will be available at terms acceptable to the Company or that any financing
transaction will not be dilutive to current stockholders or that the Company
will have sufficient working capital to fund future operations. If the Company
is not able to raise additional funds, it may be required to significantly
curtail or cease its operating activities. The accompanying financial statements
have been prepared assuming that the Company will continue as a going concern.

3.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of the
Company and of its wholly-owned subsidiary, Diagnostic Monitoring. All
inter-company accounts and transactions have been eliminated in consolidation.
The Company accounts for its investment in Biosensor Corporation ("Biosensor")
under the equity method of accounting (see note 4).

         USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the reported amounts of 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.

         RECLASSIFICATIONS

         Certain prior period balances have been reclassified to conform to the
December 31, 1998 presentation.

                                      21

<PAGE>

         CASH AND CASH EQUIVALENTS

         The Company considers all highly liquid investments with maturities of
three months or less when purchased to be cash equivalents. The Company
maintained approximately $1,011,000 of its cash in a money market fund with one
major financial institution at December 31, 1998.

         EQUIPMENT

         Property and equipment is carried at cost. Depreciation of equipment is
provided on the straight-line method over estimated useful lives of five years.
Repairs and maintenance are expensed as incurred while renewals or betterments
are capitalized. Upon the sale or retirement of equipment, the accounts are
relieved of the cost and related accumulated depreciation and any resulting gain
or loss is included in operations.

         LONG-LIVED ASSETS

         The Company evaluates the recoverability of its long lived assets in
accordance with Financial Accounting Standards ("SFAS") No. 121, ACCOUNTING FOR
THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF,
which requires long-lived assets and certain intangibles held and used by the
Company to be reviewed for impairment whenever events or circumstances indicate
that the carrying amount of an asset may not be recoverable. The recoverability
test is to be performed at the lowest level at which undiscounted net cash flow
can be directly attributable to long-lived assets.

         PER SHARE INFORMATION

         The Company has adopted SFAS No. 128, EARNINGS PER SHARE. This
statement requires the presentation of basic and diluted earnings per share, as
defined, on the statement of operations for companies whose capital structure
includes convertible securities and options.

         Net loss per share as presented in the accompanying statements of
operations is computed based on the weighted average number of common shares
outstanding and subscribed. Shares issuable upon exercise of outstanding stock
options and warrants are not included since the effects would be anti-dilutive.

         RESEARCH AND DEVELOPMENT

         Research and development costs are expensed as incurred.

         REVENUE RECOGNITION

         Prior to the sale of substantially all the assets of DM, sales and
related costs of goods sold were recognized when goods were shipped to
customers. The majority of the Company's customers were distributors who sold
goods to third party end users. The Company is not contractually obligated to
repurchase any inventory from distributors.

         STOCK-BASED COMPENSATION

         The Company has adopted the disclosure-only provisions of SFAS No. 123,
ACCOUNTING FOR STOCK-BASED COMPENSATION. SFAS No. 123 defines a fair value based
method of accounting for an employee stock option. Fair value of the stock
option is determined considering factors such as the exercise price, the
expected life of the option, the current price of the underlying stock, expected
dividends on the stock, and the risk-free interest rate for the expected term of
the option. Under the fair value based method, compensation cost is measured at
the grant date based on the fair value of the award and is recognized over the
service period. Pro forma disclosures are required for entities that elect to
continue to measure compensation cost under the intrinsic method provided by
Accounting Principles Board Opinion No. 25.

         INCOME TAXES

         The Company follows SFAS No. 109, ACCOUNTING FOR INCOME TAXES, which
requires the recognition of deferred tax liabilities and assets for the expected
future tax consequences of events that have been included in the financial
statements or tax returns. Under this method, deferred income taxes are
recognized for the tax consequences in future years of differences 

                                      22

<PAGE>

between the tax basis of assets and liabilities and their financial reporting 
amounts at each year-end based on enacted tax laws and statutory rates 
applicable to the periods in which the differences are expected to affect 
taxable income. Valuation allowances are established, when necessary, to 
reduce deferred tax assets to the amount expected to be realized. The 
provision for income taxes represents the tax payable for the period and the 
change during the period in deferred tax assets and liabilities.

4.       INVESTMENT IN UNCONSOLIDATED AFFILIATE

         On December 31, 1998, the Company acquired a 7.7% voting interest in
Biosensor as consideration for the sale of substantially all of the assets of DM
(see note 5). The Company accounts for this investment using the equity method
of accounting in accordance with Accounting Principles Board Opinion No. 18.

5.       DISCONTINUED OPERATIONS

         On December 31, 1998, the Company completed the sale of 
substantially all of DM's assets to Biosensor, a Minnesota corporation, 
pursuant to an Agreement for Purchase and Sale of Assets dated December 31, 
1998. The Company received, in consideration of the sale, 1,440,000 shares of 
common stock of Biosensor valued at $115,000. In addition, Biosensor assumed 
certain liabilities amounting to approximately $107,000. The Company 
recognized a loss of $549,618 on the sale of assets, consisting primarily of 
the unamortized balance of goodwill, as the net book value of the net assets 
sold exceeded the fair value of the consideration received.

         The Company has restated its prior financial statements to present 
the operating results of DM as a discontinued operation. Included in the loss 
from discontinued opereations is amortization of $65,713 and $49,285 for 1998 
and 1997, respectively. Operating results from discontinued operations are as 
follows:

6.       NOTES PAYABLE

         Notes payable consist of the following at December 31, 1998:

         The Company entered into a Loan and Security Agreement with a bank
dated November 14, 1997. The agreement provided for a revolving line of credit
up to $200,000 collateralized by substantially all assets of the Company and
includes certain covenants. Through November 14, 1998 the Company had net
borrowings of $125,000. The Company restructured this loan as a term loan with
twelve equal installments of $10,417 plus interest at prime plus 2% payable
beginning in January 1999.

         In September 1998, the Company borrowed $100,000 from an investor 
which was repaid in January 1999. The loan was non-interest bearing, however 
in consideration for the loan the Company issued three-year warrants to 
purchase 50,000 shares of common stock at a per share price of $2.00. Such 
warrants were assigned a fair value of $44,785 using a Black-Scholes model 
and recorded as additional paid-in capital, resulting in a debt discount. The 
debt discount was charged to interest expense during the year ended December 
31, 1998 (see note 10).

         As of December 31, 1998, the Company has research and experimentation
credit carryforwards for federal and state purposes of approximately $124,000
and $73,000, respectively. These credits begin to expire in 2010 for federal and
state purposes. The Company also has approximately $10,110,000 and $2,875,000 of
federal and state net operating loss carryforwards which will begin to expire in
2007 and 1999, respectively.

         The utilization of net operating loss and tax credit carryforwards may
be limited under the provisions of Internal Revenue Code Section 382 and similar
state provisions.

9.       STOCK OPTIONS

         1997 STOCK OPTION/STOCK ISSUANCE PLAN

         In May 1998, the Company's 1997 Stock Option/Stock Issuance Plan (the
"1997 Plan") was approved by stockholders at the Annual Meeting of Stockholders.
All outstanding stock options under the Company's 1991 Stock Option Plan and
1993 Stock Option Plan were exchanged for stock options in the 1997 Plan. The
1997 Plan provides for the granting of stock options intended to qualify as
incentive stock options and stock options not intended to qualify as incentive
stock options ("non-statutory options") to employees of the Company, including
officers, and non-statutory stock options to employees, including officers and
directors of the Company, as well as to certain consultants and advisors.

         The 1997 Plan is administered by a Compensation Committee (the
"Committee") which is comprised of three members appointed by the Company's
Board of Directors. The Committee may grant options to any officers, directors
or key employees of the Company or its subsidiaries and to any other individuals
whose participation in the 1997 Plan the Committee determines is in the
Company's best interest. Up to 705,000 shares of common stock may be issued
under the 1997 Plan, subject to adjustment upon the occurrence of certain
events, including, but not limited to, stock dividends, stock splits,
combinations, mergers, consolidations, reorganizations, reclassifications,
exchanges, or other capital adjustments. The 1997 Plan limits to $100,000 the
fair market value (determined at the time the option is granted) of the common
stock with respect to which incentive stock options are first exercisable by any
individual employee during any calendar year.

         The 1997 Plan incorporates the federal tax law requirements for
incentive stock options. Among other such requirements, the per share exercise
price of an incentive stock option granted under the 1997 Plan must not be less
than 100% of the fair market value of a share of the common stock on the date of
grant and the option may not be exercised more than 10 years after its grant
date. If an incentive stock option is granted to an employee owning more than
10% of the total combined voting power of all classes of stock of the Company,
the exercise price may not be less than 110% of such fair 

                                      25

<PAGE>

market value and the option may not be exercised more than five years after 
its grant date. Option grants under the 1997 Plan generally vest over a 
period of four years.

         Outstanding options may be terminated or accelerated in the event of
certain corporate acquisitions or other change of control events. An option
granted under the 1997 Plan will not be assignable or transferable by the
grantee other than by will or the laws of inheritance, except that a
non-statutory option will be transferable by the grantee pursuant to a qualified
domestic relations order as defined in the Code, Title I of the Employee
Retirement Income Security Act or the rules thereunder. Other vesting,
termination and payment provisions for incentive and non-statutory options may
be determined by the Committee.

         Stock option activity under the Plan is summarized as follows:

</TABLE>

         At December 31, 1998 the number of shares reserved and available for
issuance under the 1997 Plan was 108. The weighted average remaining contractual
life as of December 31, 1998 is approximately 108 months.

         The Board of Directors approved an amendment to the 1997 Plan which
increases the number of shares reserved and available for issuance under the
1997 Plan by 600,000 shares. This amendment to the 1997 Plan is subject to
stockholder approval at the Annual Meeting of Stockholders to be held in May
1999.

         For stock options granted in 1998 to non-employees (consultants), the
Company has recognized compensation cost of $17,862 for the year ended December
31, 1998 using a Black-Scholes option pricing model.

         PRO FORMA EFFECT OF STOCK-BASED COMPENSATION

         In calculating pro forma information as required by SFAS No. 123, the
fair value was estimated at the date of grant using a Black-Scholes option
pricing model with the following assumptions for the options on the Company's
common stock for the year ended December 31, 1998: risk free interest rate with
a range of 4.1% to 5.9%; dividend yield of 0%; volatility of the expected market
prices of the Company's common stock of 61.4%; and expected life of the options
of 4 years. There were no option grants in the year ended December 31, 1997.

         For purpose of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows (in thousands, except per share information):

11.      DISTRIBUTION AND LICENSE AGREEMENT

         In December 1998, Cardiac Science entered into a five-year exclusive 
distribution and licensing agreement with Medtronic Physio-Control, a 
subsidiary of Medtronic Inc. Under the agreement, Medtronic Physio-Control 
will market the Powerheart on an exclusive basis in the United States and 
Canada. Medtronic Physio-Control also obtained a license to the AECD 
Technology for integration into their in-hospital LIFEPAK-Registered 
Trademark- defibrillator-monitor products. This license is non-exclusive 
outside of the United States. The agreement also provides for Cardiac Science 
to share profits from the sale of proprietary disposable defibrillator pads 
that are used with the Powerheart as well as Physio-Control LIFEPAK 
defibrillators that include the AECD Technology.

         Pursuant to the agreement, Medtronic Physio-Control was granted 
warrants to purchase 200,000 shares of Cardiac Science common stock at $3.00 
per share. These warrants will expire in November 1999. Medtronic 
Physio-Control also will receive warrants to purchase an additional 200,000 
shares of common stock at $3.00 per share upon the sale of the 1,000th unit 
by Medtronic Physio-Control.

          (a)  TERMINATION OF EMPLOYMENT.  Employee's employment under this

upon the occurrence of any of the following events:

               (i)   The effective date of a written notice sent to the Company
from Employee stating that Employee is electing to terminate his employment with
the Company voluntarily ("VOLUNTARY TERMINATION");

               (ii)  The Company's determination that it is terminating Employee
without Cause, which determination may be made by the Company at any time at the
Company's sole discretion, for any reason or no reason ("TERMINATION WITHOUT
CAUSE");


<PAGE>


               (iii) A change in Employee's status such that a Constructive
Termination (as defined below) has occurred;

               (iv)  The Company's reasonable, good faith determination that it
is terminating Employee for Cause (as defined below) ("TERMINATION FOR CAUSE");
or

               (v)   Following Employee's death or Disability.

          (b)  SEVERANCE BENEFITS.  Employee shall be entitled to receive
severance benefits upon termination of employment only as set forth in this
Section 7(b):

               (i)   VOLUNTARY TERMINATION.  If Employee's employment terminates
by Voluntary Termination, then Employee shall not be entitled to receive payment
of any severance benefits.  Employee will receive payment for all salary and
unpaid vacation accrued as of the date of Employee's termination of employment
and Employee's benefits will be continued under the Company's then existing
benefit plans and policies in accordance with such plans and policies in effect
on the date of termination and in accordance with applicable law.

               (ii)  INVOLUNTARY TERMINATION.  If Employee's employment
terminates due to Termination Without Cause or Constructive Termination
(collectively, "INVOLUNTARY TERMINATION"), Employee will be entitled to receive
payment of severance benefits equal to Employee's regular monthly salary through
12 months following the date of such Involuntary Termination (the "SEVERANCE
PERIOD").  Such payment shall be made ratably over the Severance Period
according to the Company's standard payroll schedule. On the date of such
Involuntary Termination, Employee shall also receive the pro rata portion of
Employee's target bonus for such then current Term, based on the portion of the
current Term that Employee has worked. Health insurance benefits with the same
coverage provided to Employee prior to the termination (e.g. medical, dental,
optical, mental health) and in all other respects significantly comparable to
those in place immediately prior to the termination will be provided at the
Company's cost over the Severance Period.  Any unvested stock options or shares
of restricted stock held by Employee as of the date of Employee's termination of
employment shall continue to vest through the end of the Severance Period
according to the vesting schedule set forth in any agreement between Employee
and the Company governing the issuance to Employee of such securities.

               (iii) TERMINATION FOR CAUSE.  If Employee's employment is 
terminated for Cause, then Employee shall not be entitled to receive payment 
of any severance benefits.  Employee will receive payment for all salary and 
unpaid vacation accrued as of the date of Employee's termination of 
employment and Employee's benefits will be continued under the Company's then 
existing benefit plans and policies in accordance with such plans and 
policies in effect on the date of termination and in accordance with 
applicable law.

               (iv)  TERMINATION BY REASON OF DEATH OR DISABILITY.  In the event
that Employee's employment with the Company terminates as a result of Employee's
death or Disability (as defined below), Employee or Employee's estate or
representative will receive all salary and unpaid vacation accrued as of the
date of Employee's death or Disability and any other benefits payable under the
Company's then existing benefit plans and policies in


<PAGE>


accordance with such plans and policies in effect on the date of death or 
Disability and in accordance with applicable law. In addition, Employee's 
estate or representative shall also receive the pro rata portion of 
Employee's target bonus for the current Term, based on the portion of the 
current Term that Employee has worked.

               (vi)  CHANGE OF CONTROL.  Notwithstanding the preceding clauses
of this Section 7(b), upon a Change of Control, Employee will be entitled to
receive payment of severance benefits equal to Employee's regular monthly salary
for a period of twelve (12) months following said Change of Control (the "CHANGE
OF CONTROL SEVERANCE PERIOD").  Such payment shall be made ratably over the
Change of Control Severance Period according to the Company's standard payroll
schedule. On the date of such Change of Control, Employee shall also receive the
pro rata portion of Employee's target bonus for the current Term, based on the
portion of the current Term that Employee has worked. Health insurance benefits
with the same coverage provided to Employee prior to the Change of Control (e.g.
medical, dental, optical, mental health) and in all other respects significantly
comparable to those in place immediately prior to the Change of Control will be
provided at the Company's cost over the Change of Control Severance Period.  Any
unvested stock options or shares of restricted stock held by Employee as of the
date of Employee's termination of employment shall continue to vest through the
end of the Change of Control Severance Period according to the vesting schedule
set forth in any agreement between Employee and the Company governing the
issuance to Employee of such securities.

               (v)   NONCOMPETE.  If Employee shall at any time during a 
Severance Period or a Change of Control Severance Period, act as an owner 
(other than a shareholder in a publicly traded company) or employee of a 
business that directly competes with the business conducted by the Company as 
conducted on the date of Employee's termination of employment, then, 
effective upon Employee's commencement of such activities as a competeing

date of Employee's termination of employment, then, effective upon Employee's

comply is not remedied within fifteen (15) working days after written notice 
from the Company, which written notice shall state that failure to remedy 
such conduct may result in Termination for Cause;

               (ii)  Dishonest or fraudulent conduct related and materially
adverse to the activities of the Company, a deliberate attempt to do a material

Information and Invention Assignment Agreement, including without limitation, 
Employee's theft or other misappropriation of the Company's proprietary 
information.

          (b)  "CONSTRUCTIVE TERMINATION" shall be deemed to occur if (i)(A)

responsibilities causing such position to be of reduced stature or 
responsibility, (B) a reduction in Employee's base compensation or benefits, 
or (C) Employee's refusal to relocate to a facility or location more than 30

perform his duties hereunder as the result of his incapacity due to physical 
or mental illness, and such inability, which continues for at least 60

total and permanent by an independent and impartial physician selected by the

representative (with such agreement on acceptability not to be unreasonably 
withheld).

following events: (i) an acquisition of the Company by another entity by 
means of any transaction or series of related transactions (including, 
without limitation, any reorganization, merger or consolidation but excluding

the Company), or (ii) a sale of all or substantially all of the assets of the 
Company (collectively, a "MERGER"), so long as in either case (x) the 
Company's stockholders of record immediately prior to such Merger will,

surviving or acquiring entity, or (y) the Company's stockholders of record 
immediately prior to such Merger will, immediately after such Merger, hold 
less than 60% of the voting power of the surviving or acquiring entity AND a 
majority of the members of the Board of Directors of the surviving or 
acquiring entity immediately after such Merger were NOT members of the Board 
of Directors of the Company immediately prior to such Merger.

     Notwithstanding the above, in the event that (i) Employee's employment 
is terminated by the Company or a successor to the Company other than for 
Cause (as defined below), or (ii) Employee's job duties, responsibilities and 
requirements are materially reduced or changed such that they are 
inconsistent with Employee's prior duties, responsibilities and requirements, 
in 

<PAGE>

either case in connection with, or as a result of, a Change of Control, 
100% of the option that has not yet become exercisable shall become 
exercisable on the effective date of such termination, reduction or change. 

     9.   SUCCESSORS.  Any successor to the Company (whether direct or 
indirect and whether by purchase, lease, merger, consolidation, liquidation 
or otherwise) to all or substantially all of the Company's business and/or 
assets shall assume the obligations under this Agreement and agrees expressly

by, Employee's personal or legal representatives, executors, administrators, 
successors, heirs, distributees, devisees and legatees.

     10.  MISCELLANEOUS PROVISIONS.

          (a)  NO DUTY TO MITIGATE.  Employee shall not be required to 
mitigate the amount of any payment contemplated by this Agreement (whether by 
seeking new employment or in any other manner), nor, except as otherwise 
provided in this Agreement, shall any such payment be reduced by any earnings 
that Employee may receive from any other source.

          (b)  AMENDMENTS AND WAIVERS.  Any term of this Agreement may be 
amended or waived only with the written consent of the parties.

          (c)  SOLE AGREEMENT.  This Agreement, including any Exhibits 
hereto, constitutes the sole agreement of the parties and supersedes all oral 
negotiations and prior writings with respect to the subject matter hereof.

          (d)  NOTICES.  Any notice required or permitted by this Agreement 
shall be in writing and shall be deemed sufficient upon receipt, when 
delivered personally or by a nationally-recognized delivery service (such as

immediately prior to such Merger.

terminated by the Company or a successor to the Company other than for Cause (as
defined below), or (ii) Employee's job duties, responsibilities and requirements
are materially reduced or changed such that they are inconsistent with

Agreement, shall any such payment be reduced by any earnings that Employee may
receive from any other source.

the portion of the current Term that Employee has worked.

               (v)  CHANGE OF CONTROL.  Notwithstanding the preceding clauses of
this Section 7(b), upon a Change of Control, Employee will be entitled to
receive payment of severance benefits equal to Employee's regular monthly salary
for a period of six (6) months following said Change of Control. (the "CHANGE OF
CONTROL SEVERANCE PERIOD").  Such payment shall be made ratably over the Change
of Control Severance Period according to the Company's standard payroll
schedule. On the date of such Change of Control, Employee shall also receive the
pro rata portion of Employee's target bonus for such Term, based on the portion
of the current Term that Employee has worked. Health insurance benefits with the
same coverage provided to Employee prior to the Change of Control (e.g. medical,
dental, optical, mental health) and in all other respects significantly

provided at the Company's cost over the Change of Control Severance Period.  Any
unvested stock options or shares of restricted stock held by Employee as of the
date of Employee's termination of employment shall continue to vest through the
end of the Change of Control Severance Period according to the vesting schedule
set forth in any agreement between Employee and the Company governing the

     8.   BONUS SHARES.  In the event of a Change of Control of the Company at
any time: (a) during any Term of this Agreement; or (b) within six (6) months
following any discontinuation of Employee's employment with the Company (other
than Voluntary Termination or Termination for Cause);

          (a)  Employee shall be treated as having been Terminated Without Cause
and shall receive the payments, benefits and other provisions set forth in
Section 5(b)(ii).

          (b)  The Company shall grant, pay, issue and deliver to Employee

manner as all other outstanding shares of Common Stock of the Company. 

     9.   DEFINITIONS.  For purposes of this Agreement, 

          (a)  "CAUSE" for Employee's termination will exist at any time after
the happening of one or more of the following events:

               (i)  Employee's willful misconduct or gross negligence in
performance of his duties hereunder, including Employee's refusal to comply in
any material respect with the legal directives of the Company's Board of
Directors so long as such directives are not

<PAGE>

inconsistent with the Employee's position and duties, and such refusal to 
comply is not remedied within fifteen (15) working days after written notice 
from the Company, which written notice shall state that failure to remedy 
such conduct may result in Termination for Cause;

               (ii) Dishonest or fraudulent conduct related and materially
adverse to the activities of the Company, a deliberate attempt to do a material
injury to the Company, or conduct that materially discredits the Company or is
materially detrimental to the reputation of the Company, including conviction of
a felony; or

               (iii)     Employee's knowing and intentional material breach
(which can not be cured) of any element of the Company's Confidential
Information and Invention Assignment Agreement, including without limitation,
Employee's theft or other misappropriation of the Company's proprietary
information.

          (b)  "CONSTRUCTIVE TERMINATION" shall be deemed to occur if (i)(A)
there is a significant reduction in Employee's duties, positions or
responsibilities causing such position to be of reduced stature or
responsibility, (B) a reduction in Employee's base compensation or benefits, or
(C) Employee's refusal to relocate to a facility or location more than 30 miles
from the Company's current location; and (ii) within the 60-day period
immediately following such material change or reduction Employee elects to
terminate his employment voluntarily.

          (c)  "DISABILITY" shall mean that Employee has been unable to perform
his duties hereunder as the result of his incapacity due to physical or mental
illness, and such inability, which continues for at least 60 consecutive
calendar days or 90 calendar days during any consecutive twelve-month period, if
shorter, after its commencement, is determined to be total and permanent by an
independent and impartial physician selected by the Company and its insurers and
acceptable to Employee or to Employee's legal representative (with such
agreement on acceptability not to be unreasonably withheld).

          (d)   "CHANGE OF CONTROL" shall mean the occurrence of any of the
following events: (i) an acquisition of the Company by another entity by means
of any transaction or series of related transactions (including, without
limitation, any reorganization, merger or consolidation but excluding any merger
effected exclusively for the purpose of changing the domicile of the Company),
or (ii) a sale of all or substantially all of the assets of the Company
(collectively, a "MERGER"), so long as in either case (x) the Company's
stockholders of record immediately prior to such Merger will, immediately after
such Merger, hold less than 50% of the voting power of the surviving or
acquiring entity, or (y) the Company's stockholders of record immediately prior
to such Merger will, immediately after such Merger, hold less than 60% of the
voting power of the surviving or acquiring entity AND a majority of the members
of the Board of Directors of the surviving or acquiring entity immediately after
such Merger were NOT members of the Board of Directors of the Company
immediately prior to such Merger.

     Notwithstanding the above, in the event that (i) Employee's employment is
terminated by the Company or a successor to the Company other than for Cause (as
defined below), or (ii) Employee's job duties, responsibilities and requirements
are materially reduced or changed such that they are inconsistent with
Employee's prior duties, responsibilities and requirements, in 

<PAGE>

either case in connection with, or as a result of, a Change of Control, 100% 
of the option that has not yet become exercisable shall become exercisable on 
the effective date of such termination, reduction or change. 

     10.  SUCCESSORS.  Any successor to the Company (whether direct or indirect
and whether by purchase, lease, merger, consolidation, liquidation or otherwise)
to all or substantially all of the Company's business and/or assets shall assume
the obligations under this Agreement and agrees expressly to perform the
obligations under this Agreement in the same manner and to the same extent as
the Company would be required to perform such obligations in the absence of a
succession.  The terms of this Agreement and all of Employee's rights hereunder
shall inure to the benefit of, and be enforceable by, Employee's personal or
legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees.

     11.  MISCELLANEOUS PROVISIONS.

          (a)  NO DUTY TO MITIGATE.  Employee shall not be required to mitigate
the amount of any payment contemplated by this Agreement (whether by seeking new
employment or in any other manner), nor, except as otherwise provided in this
Agreement, shall any such payment be reduced by any earnings that Employee may
receive from any other source.

          (b)  AMENDMENTS AND WAIVERS.  Any term of this Agreement may be
amended or waived only with the written consent of the parties.

          (c)  SOLE AGREEMENT.  This Agreement, including any Exhibits hereto,
constitutes the sole agreement of the parties and supersedes all oral
negotiations and prior writings with respect to the subject matter hereof.

          (d)  NOTICES.  Any notice required or permitted by this Agreement
shall be in writing and shall be deemed sufficient upon receipt, when delivered
personally or by a nationally-recognized delivery service (such as Federal
Express or UPS), or 48 hours after being deposited in the U.S. mail as certified
or registered mail with postage prepaid, if such notice is addressed to the
party to be notified at such party's address as set forth below or as
subsequently modified by written notice.

          (e)  CHOICE OF LAW.  The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the State of
California, without giving effect to the principles of conflict of laws.

          (f)  SEVERABILITY.  If one or more provisions of this Agreement are
held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith.  In the event that the parties cannot reach a
mutually agreeable and enforceable replacement for such provision, then (i) such
provision shall be excluded from this Agreement, (ii) the balance of the
Agreement shall be interpreted as if such provision were so excluded and
(iii) the balance of the Agreement shall be enforceable in accordance with its
terms.

each of which shall be deemed an original, but all of which together will

      If Borrower does not perform any obligation in Section 6 or violates

days after it occurs, or if the default cannot be cured within 10 days or 
cannot be cured after Borrower's attempts within 10 day period, and the 
default may be cured within a reasonable time, then Borrower has an 
additional period (of not more than 30 days) to attempt to cure the default. 
During the additional time, the failure to cure the default is not an Event

9     BANK'S RIGHTS AND REMEDIES

9.1   RIGHTS AND REMEDIES.

      When an Event of Default occurs and continues Bank may, without notice 
or demand, do any or all of the following:
     
     (a) Declare all Obligations immediately due and payable (but if an Event of
Default described in Section 8.5 occurs all Obligations are immediately due and
payable without any action by Bank);
     
     (b) Stop advancing money or extending credit for Borrower's benefit under
this Agreement or under any other agreement between Borrower and Bank;
     
     (c) Settle or adjust disputes and claims directly with account debtors 
for amounts, on terms and in any order that Bank considers advisable;
     
     (d) Make any payments and do any acts it considers necessary or 
reasonable to protect its security interest in the Collateral.  Borrower 
will assemble the Collateral if Bank requires and make it available as Bank 
designates. Bank may enter premises where the Collateral is located, take and

                                      
<PAGE>

maintain possession of any part of the Collateral, and pay, purchase, 
contest, or compromise any Lien which appears to be prior or superior to its 
security interest and pay all expenses incurred. Borrower grants Bank a 
license to enter and occupy any of its premises, without charge, to exercise 
any of Bank's rights or remedies;

     (e) Apply to the Obligations any (i) balances and deposits of Borrower 
it holds, or (ii) any amount held by Bank owing to or for the credit or the 
account of Borrower;

     (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for
sale, advertise for sale, and sell the Collateral. Bank is granted a
non-exclusive, royalty-free license or other right to use, without charge,
Borrower's labels, Patents, Copyrights, Mask Works, rights of use of any name,
trade secrets, trade names, Trademarks, service marks, and advertising matter,
or any similar property as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section, Borrower's
rights under all licenses and all franchise agreements inure to Bank's benefit;
and

     (g) Dispose of the Collateral according to the Code.
     
9.2  POWER OF ATTORNEY.
 
     Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrower's name
on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as the Code
permits. Bank may exercise the power of attorney to sign Borrower's name on any
documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred. Bank's
appointment as Borrower's attorney in fact, and all of Bank's rights and powers,
coupled with an interest, are irrevocable until all Obligations have been fully
repaid and performed and Bank's obligation to provide Credit Extensions
terminates.
     
9.3  ACCOUNTS COLLECTION.

     When an Event of Default occurs and continues, Bank may notify any Person
owing Borrower money of Bank's security interest in the funds and verify the
amount of the Account. Borrower must collect all payments in trust for Bank and,
if requested by Bank, immediately deliver the payments to Bank in the form
received from the account debtor, with proper endorsements for deposit.
     
9.4  BANK EXPENSES.

     If Borrower fails to pay any amount or furnish any required proof of 
payment to third persons Bank may make all or part of the payment or obtain 
insurance policies required in Section 6.5, and take any action under the 
policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and 
immediately due and payable, bearing interest at the then applicable rate and 
secured by the Collateral. No payments by Bank are deemed an agreement to 
make similar payments in the future or Bank's waiver of any Event of Default.
     
9.5  BANK'S LIABILITY FOR COLLATERAL.

     If Bank complies with reasonable banking practices it is not liable for 
(a) the safekeeping of the Collateral; (b) any loss or damage to the 
Collateral; (c) any diminution in the value of the Collateral; or (d) any act 
or default of any carrier, warehouseman, bailee, or other person. Borrower 
bears all risk of loss, damage or destruction of the Collateral.

<PAGE>

9.6  REMEDIES CUMULATIVE.

     Bank's rights and remedies under this Agreement, the Loan Documents, and 
all other agreements are cumulative. Bank has all rights and remedies 
provided under the Code, by law, or in equity. Bank's exercise of one right 
or remedy is not an election, and Bank's waiver of any Event of Default is 
not a continuing waiver. Bank's delay is not a waiver, election, or 
acquiescence. No waiver is effective unless signed by Bank and then is only 
effective for the specific instance and purpose for which it was given.
     
9.7  DEMAND WAIVER.

     Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

     2.0  ASSUMPTION OF LIABILITIES.

     2.1  OBLIGATIONS TO BE ASSUMED BY PURCHASER.  Purchaser agrees to assume
     and to pay, perform and discharge in accordance with their respective
     terms, from and after the Closing Date, each of the following obligations
     or commitments of Seller (the "Assumed Liabilities"):(A) trade accounts
     payable and accrued expenses incurred in the normal course of business and
     directly associated with the Product Line sold under the name Diagnostic
     Monitoring (excluding employment and travel expenses incurred by Victor
     Bravo through the Closing Date), to be agreed upon by Purchaser and Seller
     prior to Closing and a complete schedule of which is attached as Schedule
     2.1, and (B) warranty obligations accrued in the ordinary course of
     business for Seller, but solely with respect to 1/0 board patient recorders
     which have been sold or delivered prior to the Closing Date, but only if
     and to the extent the same have not been paid or discharged prior to the
     Closing Date. The parties acknowledge that the foregoing liabilities and
     obligations, excluding warranty obligations, if any, referred to in (B)
     above, totaled approximately $110,000 as of November 30, 1998. Assets
     less Assumed Liabilities ("Net Book Value") shall not be less than
     $100,000. Any special obligations or liabilities, if any, to employees, or
     ex-employees of Seller are not assumed by Purchaser.
     
     The assumption by Purchaser of the Assumed Liabilities shall not enlarge
     any rights of any person under contracts or arrangements with Seller.
     
     Nothing contained herein shall prevent Purchaser from contesting in good
     faith any of the Assumed Liabilities with any third party obligee.    
     
     3.0   PURCHASE PRICE
     
     The purchase price for the Assets shall equal the aggregate of (i) the
     Assumed Liabilities, and (ii) 1,440,000 shares of common stock of
     Purchaser (this amount represents the "Initial Purchase Price"), subject to
     the post closing adjustments provided in Section 3.1.  On the Closing Date,
     Purchaser shall (I) assume the Assumed Liabilities, and  (II) issue to
     Seller 1,440,000 shares of its common stock.   Seller acknowledges that
     Purchaser has proposed a one share for six reverse stock split that is
     pending shareholder approval, and upon approval of same the consideration
     hereunder shall represent 240,000 shares, all as described in Purchaser's
     Preliminary Proxy Statement filed with the Securities and Exchange
     Commission on December 4, 1998. Following the reverse stock split (A) there
     will be a total of approximately 3,125,000 shares of Purchaser's common
     stock outstanding, (B) no preferred stock issued and outstanding, and (C)
     options, warrants, convertible securities and other commitments for an
     additional ________ shares of its common stock outstanding.  Seller
     acknowledges that the most recent price paid by new investors of
     Purchaser's common stock was in May of 1998, and was the equivalent of
     $2.08 per share (on a post-reverse stock split basis). 
     
     3.1  POST CLOSING ADJUSTMENT.  The Initial Purchase Price is based on the
     assumption that the Net Book Value of the Business will be at least
     $100,000 as of the Closing Date.  Within twenty (20) days after the Closing
     Date, Seller shall cause to be prepared and delivered to Purchaser an
     unaudited list of Assets and Assumed Liabilities for the Product Line as of
     the close of business on the Closing Date (the "Closing Balance Sheet") and
     a computation of the Net Book Value of the Product Line as of the Closing
     Date.  The Closing Balance Sheet shall be prepared in conformity with
     generally accepted accounting principles ("GAAP"), applied on a basis
     consistent with Seller's Financial Statements and shall present fairly the
     Assets and Assumed Liabilities of Seller as of that date; provided that
     there shall not be included in the Closing Balance Sheet any asset which is
     an Excluded Asset.


<PAGE>

     Within ten (10) days after the delivery of the Closing Balance Sheet,
     Purchaser may notify Seller in writing of any objections or changes to the
     Closing Balance Sheet or computation of Net Book Value, specifying in
     reasonable detail any such objections or changes, and the parties shall
     attempt in good faith to resolve any such dispute.  If the parties cannot
     resolve such dispute within a period of twenty (20) days commencing from
     Seller's receipt of the Purchaser's notification, the parties shall submit
     the matter to McGladrey Pullen, LLP (the "Accountant") whose decision with
     respect to the disputed matter shall be binding on the parties.  The
     prevailing party shall be entitled to receive from the other party its
     costs and expenses, including reasonable attorneys fees in connection with
     its objection or defense to the calculation of Net Book Value.  The fees
     and expenses of the Accountant shall be paid by the party against whom a
     decision is rendered.  The prevailing party shall be the party whose
     proposed Net Book Value is closest to the Net Book Value finally determined
     by the Accountant.
     
     If the Net Book Value as of the Closing Date, as finally determined as
     provided in this Section 3.1, is less than $100,000, the Seller shall pay
     to Purchaser the amount of the deficit in cash; and if the Net Book Value
     is greater than $100,000, Purchaser shall pay to Seller the amount of the
     excess in additional shares of common stock based on a pre-reverse split
     value of $0.3472 per share, not to exceed 210,000 additional shares (or
     35,000 shares post reverse stock split). 
     
     3.2  UNREGISTERED SHARES  All shares of common stock of the Purchaser
     issued to the Seller will not have been registered under the Securities Act
     of 1933, as amended (the "Act"), on the basis that (i) this transaction is
     exempt under the Act and such shares shall have the status of securities
     acquired under Section 4(2) of the Act, as not involving any public
     offering, and (ii) in the view of the Securities and Exchange Commission
     (the "SEC"), the statutory basis for the exemption would not be present,
     if, notwithstanding the forgoing, the Seller has a present intention to
     dispose of such shares or any portion thereof.
     
     3.3  PIGGYBACK REGISTRATION RIGHTS   All of the shares of common stock of
     the Purchaser issued to the Seller shall have "piggy back" registration
     rights to be included in the next registration statement filed by the
     Purchaser with the Securities and Exchange Commission.  Purchaser has a
     current intention to file an S-4 Registration Statement during the first
     calendar quarter of 1999, but no assurance can be given that any
     Registration Statement will be filed, or if filed, whether it will become
     effective.  If registered under the Act, Seller's shares of Purchaser's
     stock shall also be registered under such state securities laws as Seller
     may reasonably request.
     
     3.4   SELLER'S RELIANCE ON PURCHASER'S FINANCIAL AND OTHER INFORMATION
     PUBLICLY ON FILE.    In determining the value of the securities to be
     issued in exchange for the Assets purchased, Seller acknowledges that it is
     relying solely on the financial and other information regarding the
     Purchaser's financial condition, operating results and business and other
     matters that is on file with the Securities and Exchange Commission (Forms
     10-KSB, 10-QSB, 8-K and Preliminary Proxy Statements).  Such financial
     information has been prepared in accordance with GAAP, is audited where
     appropriate, and to the best of the Purchaser's belief is current as
     regards SEC filing requirements.  Seller further acknowledges that
     Purchaser has not made and is not making any representations or warranties
     with respect to itself other than as expressly set forth in this Agreement
     and for the information contained in its materials filed with the
     Securities and Exchange Commission.
     
     4.0   REPRESENTATIONS AND WARRANTIES OF SELLER.
     
     As a material inducement to Purchaser to enter into this Agreement and with
     the understanding that Purchaser will be relying thereon in consummating
     the transactions contemplated by this Agreement, Seller represents and
     warrants to Purchaser as follows:

4.4   SELLER AS AN INVESTOR IN THE PURCHASER'S SECURITIES   Seller 
acknowledges that in accepting Purchaser's common stock as payment for the 
Assets, Seller becomes an investor in the common stock of the Purchaser, and 
in that capacity Seller represents and warrants to and with Purchaser as 
follows:

     4.4.1   HIGH DEGREE OF RISK   Seller acknowledges that investment in
     Purchaser's stock is speculative and involves a high degree of risk and the
     possible loss of its entire investment.
     
     4.4.2   REVIEW OF AVAILABLE FINANCIAL INFORMATION   Seller is familiar with
     the operations of the Purchaser, has evaluated the merits and risks of this
     transaction, has made its independent judgment as to the value of the
     securities to be issued in exchange for the Assets purchased by reviewing
     the financial and other information regarding the Purchaser that is
     publicly available and on file with the Securities and Exchange Commission
     (Forms 10-KSB, 10-QSB, 8-K and Preliminary Proxy Statements).  Seller has
     had the opportunity to request additional information and to ask questions
     and receive answers concerning the business operations of Purchaser, and is
     satisfied with the results of it investigation of the Purchaser.  
     
     4.4.3   ACQUIRED SHARES FOR INVESTMENT   Seller is acquiring the
     Purchaser's shares in good faith for the purpose of investment in the
     Purchaser and not for the purpose of distributing or publicly selling the
     shares to others, reselling, assigning, pledging or hypothecating the
     shares, or dividing its participation in ownership of the shares with
     others, except that Seller may transfer the shares to its parent company,
     CSI. 
     
     4.4.4.  UNREGISTERED SHARES.   Seller understands and acknowledges that it
     has been advised by the Purchaser that shares of the common stock of
     Purchaser will not have been registered under the Act, on the basis that
     (i) this transaction is exempt under the Act and the shares shall have the
     status of securities acquired under Section 4(2) of the Act, as not
     involving any public offering, and (ii) in the view of the Securities and
     Exchange Commission (the "SEC"), the statutory basis for the exemption
     would not be present, if, notwithstanding the forgoing, the Seller has a
     present intention to dispose of such shares or any portion thereof.  Seller
     acknowledges that the Purchaser is relying on the statutory exemption from
     the registration requirements under the Minnesota Securities Act, basing
     its reliance in part on the Seller's representations set forth in this
     agreement.
     
     4.4.5. [INTENTIONALLY OMITTED]
          
     4.4.6.  NO ASSURANCE OF LIQUIDITY   Seller recognizes that the Purchaser
     may not comply in the future with the requirements which would permit it to
     sell the shares of Purchaser pursuant to Rule 144.  As such, Seller agrees
     that such shares may have to be held for an indeterminate period of time. 
     Seller understands that the certificates representing the shares shall be
     stamped with a legend in substantially the following form:

                                      
<PAGE>

                "The shares of common stock represented by this certificate 
                have not been registered under the Securities Act of 1933 or 
                under applicable state securities laws and may not be sold, 
                transferred, or pledged in the absence of such registration, 
                unless pursuant to an exemption from the registration 
                requirements of the Securities Act of 1933 and applicable state
                securities laws.  The Company reserves the right to require on 
                opinion of counsel satisfactory to it before effecting any 
                transfer of the shares."
           
          Purchaser's shares cannot be expected to be readily liquidated, 
          if at all. Seller is aware that there is currently a very limited 
          public market for the shares of Purchaser and that there is no 
          assurance that a more liquid market will develop.
     
          4.4.7  FORWARD LOOKING STATEMENTS NOT INDICATIVE   Seller acknowledges
          that the available financial statements and forecasts cannot be
          relied upon as an indication of future results.  Future operations of
          Purchaser will be dependent, in part, on the market acceptance of its
          products, "Health Care Reform" legislation, health insurance
          reimbursement policies, the status of the economy and its effect on
          the market for diagnostic health care products, competition, changes
          in demographic characteristics of the market or shifts in emphasis
          regarding health care, and on management's ability to control
          operating expenses.  Many of these factors cannot be controlled by
          Purchaser.  No representation had been made that actual results of
          operations will conform to historical results or forecasted results.
         
     4.5   LAWSUITS; PROCEEDINGS; ETC.   Seller is not engaged in any legal
     action or other proceedings before any court or administrative agency. 
     Seller is not a party to any action or proceeding, nor has Seller been
     threatened with any such action or proceeding, nor, to the Knowledge of
     Seller, does there exist any basis therefor, which will or could have a
     material adverse effect on the condition, financial or otherwise, of the
     Assets or the Product Line. No order, writ, injunction or decree has been
     issued by, or requested of, any court or governmental agency which does or
     may result in any material adverse change in the Assets or in the selling
     or servicing of the Product Line.
     
     4.6   ASSETS.   All of the tangible Assets, whether or not reflected on the
     Balance Sheet, are being acquired by Purchaser on an "as-is, where is" 
     basis. Except as otherwise set forth in this Agreement, SELLER MAKES NO
     WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT TO ANY SUCH ASSETS ACQUIRED BY
     PURCHASER HEREUNDER, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF
     MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.  The Assets constitute
     all of the operating assets and properties that have been used by Seller in
     the manufacturing and distribution of the Product Line and comprise all
     those properties, assets and rights of Seller necessary to operate the
     Product Line under the name Diagnostic Monitoring in the ordinary course of
     business.
     
     4.7 INVENTORY:   All inventories reflected on Schedule 4.3 (vii) are stated
     at the lower of cost or market value determined using the first-in,
     first-out ("FIFO") method of accounting.  All inventories reflected on such
     Schedule shall be stated at the lower of cost or market determined using
     the FIFO method of accounting.  All inventories reflected on such Schedule
     are used in the manufacture and distribution of the Product Line, regularly
     offered from current price lists.  All inventories are being acquired by
     Purchaser on an "as-is, where is" basis.  Except as otherwise set forth in
     this Agreement, SELLER MAKES NO WARRANTIES, EXPRESS OR IMPLIED, WITH
     RESPECT TO ANY INVENTORIES, WORK IN PROGRESS OR RAW MATERIALS ACQUIRED BY
     PURCHASER HEREUNDER, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF
     MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
     
     4.8  COMPLIANCE WITH LAWS; PERMITS.   Seller has complied in all material
     respects with all applicable statutes, regulations, orders, ordinances and
     other laws of the United States of America, all state, local 

                                      
<PAGE>

     and foreign governments and other governmental bodies and authorities, 
     and agencies of any of the foregoing to which they are subject in 
     connection with the operation of the Product Line under the name 
     Diagnostic Monitoring.  Seller has not received any notice to the effect 
     that, or otherwise been advised that, Seller is not in compliance with 
     any of such statutes, regulations and orders, ordinances, other laws or 
     undertakings as they might relate to any manner whatsoever to the Product
     Line.
     
     4.9   INTANGIBLE PROPERTIES.   The Intangible Property Rights listed on
     Schedule 4.3 (iii) to this Agreement are all those used by or useful to the
     Product Line and are valid and in full force and effect.  All patents,
     copyrights and trademarks have been duly registered or filed in the United
     States Patent and Trademark Office, and such registrations have been
     properly maintained and renewed in accordance with all applicable laws,
     rules and regulations.
     
     Seller has good and marketable title to and owns or exclusively holds all
     rights to use, free and clear of all liens, claims, restrictions, and
     infringements, the Intangible Property Rights.  The Intangible Property
     Rights are valid, subsisting, enforceable and in full force and effect. 
     There is no infringement or other adverse claim pending against any of the
     Intangible Property Rights.  In connection with the operation of the
     Business, Seller is not obligated or under any liability whatsoever to make
     any payments by way of royalties, fees or otherwise with respect to
     third-party patents, trademarks, copyrights  or other intellectual property
     in connection with the conduct of the Business.
     
     4.10   CHANGES IN CUSTOMERS OR SUPPLIERS.   Seller has not received any
     notice that any major customer or supplier of the Product Line intends to
     terminate, limit or reduce its business relations with Seller either
     currently or following the consummation of the transactions contemplated by
     this Agreement.  No customer or supplier which was material to the Product
     Line in the past twelve month period has terminated, materially reduced or,
     to the knowledge of Seller, threatened to terminate or materially reduce
     its purchases from or provision of products or services to the Product
     Line.
     
     4.11  BROKERS OR FINDERS.   No person, firm or corporation has or will
     have, as a result of any act or omission of the Seller, any right, interest
     or valid claim against Purchaser for any commission, fee or other
     compensation as a finder or broker in connection with the transactions
     contemplated by this Agreement.
     
     4.12   ACCOUNTS AND NOTES RECEIVABLE.  The accounts receivable of Seller
     that are part of the Assets being transferred hereby (i) have and shall
     have arisen only from bona fide transactions in the ordinary course of
     business, and (ii) represent and will represent valid and binding
     obligations of the account debtors, not subject to defense or offset to
     which such receivables relate.
     
     4.13  ENVIRONMENTAL MATTERS.  Schedule 4.13 to this Agreement contains a
     complete list of all permits, consents, licenses and authorizations related
     to the Product Line obtained by Seller under the Environmental Laws.  The
     Seller is in compliance with all terms and conditions of the permits,
     consents, licenses, approvals, and authorizations listed on Schedule 4.13
     to this Agreement.
     
     There is no civil, criminal, or administrative action, suit, demand, claim,
     hearing, notice or demand letter, notice of violation, investigation, or
     proceeding pending or, to the Knowledge of Seller, threatened against
     Seller, the Assets, or the operations and properties currently or
     previously owned, leased, or used with respect to the Product Line relating
     in any way to the Environmental Laws.
     
     With respect to the Product Line, and any currently or previously owned,
     leased, or used properties or operations, there are no past or present
     events, conditions, circumstances, activities, practices, incidents,
     actions, or plans that interfere with or prevent compliance or continued
     compliance with the Environmental Laws or which may give rise to any
     liability (whether statutory or common law) or otherwise form the basis of
     any claim, action, demand, suit, proceeding, hearing, notice of violation,

                                      
<PAGE>

     study, or investigation arising under any Environmental Law or otherwise
     based on or related to the generation, manufacture, processing,
     distribution, use, treatment, storage, disposal, transport, or handling, or
     the release into the workplace, the community, or the environment of any

     in the ordinary course of business).

     statement not misleading.

     contract, agreement, license or other instrument or obligation to which
     Seller or CSI is a party or by which the Assets are bound.  The execution,
     delivery and performance of this Agreement or the other agreements

     require the consent, approval, permission or other authorization of any
     court, arbitrator or governmental, administrative or self-regulatory
     authority or any other third party.

     5.3   FULLY PAID AND VALIDLY ISSUED SHARES.    Purchaser's shares, when
     issued and delivered to Seller, shall be deemed to be, and shall be, fully
     paid and validly issued shares of stock of Purchaser and Seller shall not

     thereto.

     statements and the unaudited quarterly and pro forma combined financial

     5.7   NO BROKERS OR FINDERS.  No person, firm or corporation has or will

     or valid claim against Seller for any commission, fee or other compensation
     as a finder or broker in connection with the transactions contemplated by
     this Agreement.
     
     5.8   DISCLOSURE.   No representation or warranty of Purchaser in this

     6.0   POST-CLOSING AGREEMENT.  Seller hereby covenants and agrees with
     Purchaser as follows:

     6.1   NON-COMPETITION.   In consideration of the benefits to Seller
     hereunder and in order to induce Purchaser to enter into this Agreement,
     Seller hereby covenants and agrees that for a period of two (2) years after
     the Closing Date, Seller shall not, and Seller shall cause each corporation
     or other entity, controlling, controlled by or under common control with,
     Seller to not, directly or indirectly, anywhere in the world where the
     Product Line is currently produced, marketed, sold or used, as a
     proprietor, partner, stockholder, director, officer, employee, joint
     venturer, investor, lender, guarantor or in any other capacity own, engage
     in, conduct, manage, operate or control, or participate in, be associated
     with or be connected  in any manner whatsoever in the ownership,
     management, operation or control 

                                      
<PAGE>

     of, any business which, directly or indirectly, is competitive with the 
     Product Line, except that this non-competition obligation shall not apply 
     as follows:

          (i)   Ownership by Seller or any of its affiliates, in the aggregate,
                of less than five (5%) percent of the outstanding shares of
                capital stock of any corporation with one (1) or more classes
                of its capital stock listed on a national securities exchange
                or publicly traded in the over-the-counter market shall not
                constitute a violation of this Section 6.1; and

          (ii)  The provisions of this Section 6.1 shall not preclude Seller or
                any of its affiliates from acquiring control of an entity which
                has a portion of its business which competes with the Business
                (the "Competing Business"), provided the Competing Business
                does not represent more than five (5%) percent of the total
                business conducted by such entity.

     (a)  Seller hereby covenants and agrees that for a period of two (2) years
          after the Closing Date, Seller shall not, and Seller shall cause each
          person, corporation or other entity related to, controlling or
          controlled by, directly or indirectly, Seller to not, without the
          prior written consent of Purchaser, (A) solicit or employ any employee
          of Purchaser (i.e.: Victor Bravo) at any time on or after the date
          hereof to become an officer, director, employee, agent, consultant or
          otherwise affiliated with Seller, or any entity in which Seller owns
          an equity or debt interest or has the power to direct management or
          (B) solicit at any time on or after the date hereof any employee of
          Purchaser (i.e.: Victor Bravo) to terminate his or her relationship
          with the Purchaser.

     (b)  Seller will not at any time from and after the Closing Date divulge,
          furnish to or make accessible to anyone any knowledge or information
          with respect to confidential or secret processes, inventions,
          discoveries, improvements, formulae, plans, material, devices or ideas
          or know-how, whether patentable or not, with respect to any
          confidential or secret aspects of the Product Line (including, without
          limitation, customer lists, supplier lists and pricing arrangements
          with customers or suppliers) (collectively, "Confidential
          Information").  Any portion of such information and only such portion,
          which (i) at or prior to the time of disclosure was generally
          available to the public through no breach of this covenant, (ii) was
          available to the public on a non-confidential basis prior to its
          disclosure, or (iii) is required to be disclosed by law or by order of
          a court of competent jurisdiction, shall not be deemed Confidential
          Information for purposes of this Agreement, and the undertakings in
          this covenant with respect to Confidential Information shall not apply
          thereto.

     (c)  Seller hereby covenants and agrees that, for a period of two (2) years
          after the Closing Date, Seller shall not, and Seller shall cause each
          person, corporation or other entity related to, controlling or
          controlled by, directly or indirectly, Seller to not solicit or
          attempt to solicit any of the current customers, clients or accounts
          with respect to the Product Line and such other customers, clients or
          accounts to whom Seller, directly or indirectly, sold goods or
          services in the Product Line during the 24 month period immediately
          preceding the Closing Date, with the intent or purpose to perform for
          such customer, client or account the same or similar services sold by
          Seller or to sell to such customer, client or account the same or
          similar goods or services which was performed by Seller for or sold to
          such customer, client or account.

     (d)  In the event a court of competent jurisdiction deems any provision in
          this Section 6.1 to be unreasonable, unenforceable or invalid, then
          such provision(s) shall be interpreted as broadly as may be

     The parties acknowledge and agree that the breach of the provisions of this
     Section 6.1 could not be adequately compensated with monetary damages and
     would irreparably injure Purchaser, and, accordingly, that injunctive
     relief and specific performance shall be appropriate remedies to enforce
     the provisions of this Section, and the parties waive (a) any claim or
     defense that there is an adequate remedy at law for such breach, and (b)
     the necessity of posting a bond or similar security;  PROVIDED, HOWEVER,
     that nothing contained herein shall limit the remedies, legal, or
     equitable, otherwise available to Purchaser, and all remedies of the
     parties herein are in addition to any remedies available to the parties at
     law or otherwise.

          operations prior to the Closing Date for a period of three (3) years

          matters and other reasonable business purposes.  Purchaser shall

     Date for the purposes of (a) preparing and /or defending tax returns for
     any period prior to the Closing Date, (b) obtaining information relating to
     claims arising from the conduct of the business of the Product Line prior
     to the Closing Date, or (c) for such other purposes as Seller may
     reasonably request.  During such three (3)-year period, Purchaser shall
     make the records available to Seller and shall not destroy or discard such
     financial records without giving Seller thirty (30) days prior written
     notice of its intentions and giving Seller the right, at its expense, to
     remove from Purchaser's premises any such financial records.  Seller shall
     reimburse Purchaser for all out-of-pocket costs incurred in complying with
     this Section 6.2, other than with respect to the storage of records.

     the payment and the related invoice number. Seller agrees to endorse and
     Purchaser shall have the right to endorse the name of Seller on any such

     Date, Seller shall cooperate with, and provide reasonable assistance to,

             PHYSICIAN SERVICES, INC. (DBA DIAGNOSTIC MONITORING) AND 
                                BIOSENSOR CORPORATION


                                    SCHEDULE 5.5

Capitalization

     Biosensor's Articles of Incorporation currently provide that the Company is
authorized to issue up to 5,000,000 shares of capital stock, of which 4,850,000
has been designated Class A common stock and 150,000 of which has been
designated as Series A Preferred Stock. The total number of shares of capital
stock outstanding as of December 31, 1998 consisted of 3,008,055 shares of $.05
par value common stock and 149,025.15 shares of no par value Series A Preferred
Stock. While each share of common stock is entitled to one vote, each share of
Series A Preferred Stock is entitled to 96 votes. Holders of the preferred
shares hold approximately 83% of the voting power of all shares (including both
common and preferred) entitled to vote. There is no cumulative voting.  Of the
4,850,000 authorized shares of common stock, 3,008,055 shares are issued and
outstanding, 82,500 are reserved for issuance upon exercise of outstanding
options, and 1,759,445 shares are available for issue.  If 1,440,000 shares of
common stock are issued to Innovative Physician Services as contemplated by this
Agreement, 4,448,055 shares of common stock will then be issued and outstanding,
and 319,445 shares of common stock will be available for issue.  Holders of the
preferred shares would then hold approximately 76% of the voting power of all
shares entitled to vote.
     
     On July 23, 1998, Biosensor Corporation ('Biosensor" or the "Company")
acquired all of the outstanding shares of Carolina Medical, Inc. pursuant to a
Plan of Reorganization and Agreement which requires the Company to submit to its
shareholders proposals: i) to change the Company's name to BIOTEL Inc., ii) to
effect a one-for-six reverse stock split (the "Reverse Stock Split"), and iii)
to increase the authorized number of shares of common stock to 10,000,000 and
the authorized number of preferred stock shares to 2,000,000. A Preliminary
Proxy Statement filed with the Securities and Exchange Commission on December 4,
1998 includes the above proposals. 
     
     If the proposed Reverse Stock Split is approved, there will be 808,333.333
shares of common stock authorized of which 501,342 will be issued and
outstanding.  The authorized number of Series A Preferred Stock will be
unaffected by the Reverse Stock Split.  The number of shares of common stock
issuable upon conversion of the Series A Preferred Stock will, however, be
reduced from 14,400,000 to 2,400,000. In addition, if the Reverse Stock Split is
approved, the Company will have 306,991 shares of common stock that are
authorized but unissued, of which 13,750 will be reserved for issuance upon
exercise of outstanding options and 293,241 shares will be available to issue.
If 1,440,000 shares of pre-reverse split common stock are issued to Innovative
Physician Services as contemplated by this Agreement, these shares will be
replaced by 240,000 post reverse split shares, bringing the total number of
common shares issued and outstanding to 741,341 and leaving 53,241 shares of
common stock available for issue.


<PAGE>


     If the proposal to increase the authorized number of shares of common stock
to 10,000,000 and the authorized number of preferred stock shares to 2,000,000
is approved, the 149,025.15 Series A Preferred Shares will automatically be
converted to 2,384,402 shares of common stock, increasing the total number of
common stock shares issued and outstanding to 2,885,744.  The number of
available common stock shares would then be 7,114,256 and the number of
available preferred stock shares would be 2,000,000. If 240,000 post reverse
split shares of common stock are issued to Innovative Physician Services as
contemplated by this Agreement, the total number of common shares issued and
outstanding will be 3,125,744, 13,750 shares will be reserved for options, and 
6,860,506 shares of common stock will remain authorized and available for issue.
       
Principal Shareholders

     Of the thirty-two (32) Series A Preferred Stock holders, the following
eight (8) own more than four (4) per cent of the current voting power of the
Company.

*    calculated as if all issued and outstanding shares of Series A Preferred
     Stock were converted into Common Stock at the ratio of 96 shares of Common
     Stock for each share of Series A Preferred Stock.   

     In addition to the above holders of Series A Preferred Stock, Steven
Springrose owns 5.2% of the voting power of the Company as a result of his
beneficial ownership of 896,000 shares of the Company's Common Stock.  

     Other than in connection with: i) this Agreement, and ii) the possible
merger of Advance Medical Products, Inc. into Advanced Biosensor, Inc., a wholly
owned subsidiary of the Company, the Company has no current plans, agreements or
arrangements for the issuance of additional shares of common stock or Preferred
Stock, other than the issuance of shares pursuant to its stock option and other
employee benefit plans. The Company is at all times investigating additional
sources of financing and future acquisitions which the Board of Directors
believes will be in the best interests of the Company and its shareholders.  In
addition, the Company is currently seeking and plans to continue to seek
additional financing, which could involve the issuance of debt or equity of the
Company.

                            2  DISTRIBUTION OF PRODUCTS
                                          
     2.1  APPOINTMENT.  Subject to the terms and conditions of this Agreement
          and during the term hereof, Physio shall be the exclusive authorized
          dealer and distributor of the Products for all sales to the Hospital
          Market anywhere in the United States and Canada ("Exclusive
          Territory")..  During the period of exclusivity, Cardiac Science shall
          not sell, authorize or knowingly permit any other party to sell, any
          Products to an end customer for use in the Hospital Market within the
          Exclusive Territory.  Exclusivity is conditioned upon Physio
          purchasing at least the following minimum number of Products or
          Software Technology (or a combination of both which totals the
          following), following successful completion (and availability in
          commercially reasonable quantities) of the commercial version of the
          Products:
     
               First 12 months     1,000
               Second 12 months    1,600
               Third 12 months     2,400
               Fourth 12 months    3,600
               Fifth 12 months     5,400
          
          If Physio fails to purchase the minimum number in any period it will
          have a six (6) month period within which to cure any shortfall.  At
          its election, Physio may purchase Products or Software Technology in
          advance of their sale to end customers for the purpose of satisfying
          the foregoing minimum requirements.
          
          If Physio does not cure any shortfall within the six (6) month cure
          period, Cardiac Science may terminate Physio's representation of
          Products, upon not less than thirty (30) days prior written notice to
          Physio.  In the event Physio's distribution rights to Products
          terminate under the terms of this Section 2.1, Cardiac Science shall
          be entitled to develop, manufacture and sell disposable defibrillator
          pads with a Proprietary Chip embedded in the connector component
          thereof compatible with Products; provided that such disposable
          defibrillator pads will not be compatible with Defibrillator-Monitors
          manufactured by or for Physio and provided that Cardiac Science shall
          be responsible for all forecasts which it has provided to Physio for
          the purchase of disposable defibrillator pads.

            POWERHEART-Registered Trademark- AECD-Registered Trademark-
                     DEFIBRILLATOR-MONITOR PRODUCT SUMMARY

1.   DEVICE OVERVIEW

The Powerheart-Registered Trademark- AECD-Registered 
Trademark- defibrillator-monitor represents a significant advancement in 
defibrillator technology and the ability to effectively manage 
life-threatening arrhythmias in a hospital environment.  Drawing on the 
technologies that have made "hands-off" defibrillation and implantable 
defibrillation possible and fusing this with advanced monitoring 
capabilities, the Powerheart introduces the unique ability to provide 
continuous monitoring of patients at risk for Sudden Cardiac Arrest. If a 
patient suffers cardiac arrest, the Powerheart automatically detects and 
restores a normal heart rhythm within seconds. 

The Powerheart is a fully functional defibrillator that can be programmed to 
identify and treat life-threatening arrhythmias.  The Powerheart is capable 
of providing as many as eight defibrillation shocks of up to 360 joules for 
each life-threatening ventricular tachyarrhythmia event that occurs.  This 
unique protection is available to the patient throughout the period of high 
risk whether that time is hours, days, or weeks.  Similar to other diagnostic 
monitoring devices that may be attached to the patient in this environment, 
the Powerheart provides a patient cable to allow limited mobility customarily 
available to less critical patients, as well as providing flexibility to the 
nursing staff. 

In addition to the standard AC power, the Powerheart also has a backup 
battery that provides up to one hour of freestanding use.  This battery is 
automatically recharged whenever the Powerheart is plugged in, so that it is 
always ready for use.  The battery provides reliable backup in case of a 
power outage as well as allowing the Powerheart to go with the patient should 
the patient need to be moved. 

The Powerheart attaches to the patient using disposable defibrillation 
electrodes.  Four additional monitoring electrodes may also be attached 
providing up to three separate electrocardiogram (ECG) signals (channels) for 
analysis.  These additional channels provide the physician with the ability 
to select and change the channel of ECG to be analyzed.  Once the patient is 
attached, the operator can program the Powerheart according to the 
physician's prescription.  The Powerheart will verify hookup quality. 
Assuming the patient is in a normal rhythm, the operator will proceed to 
program the device and allow for automatic analysis. 

During the analysis period, the Powerheart can communicate with the medical 
staff in a variety of ways.  The ECG is always available for review on the 
LCD display.  This display provides important patient ECG information 
regarding the analysis such as heart rate and rhythm.  The printer will 
provide hard copy documentation in standard ECG "strip chart" format.  These 
strips are printed automatically during a cardiac event. They may also be 
printed whenever the operator 

                                                                            1

desires.  The Powerheart also stores one hour of information in a continuous 
loop.  This data can be transmitted to a personal computer for detailed 
review and/or printing.  In the case of a cardiac event, or any situation 
requiring operator attention, the Powerheart can alert the operator through 
an appropriate combination of visual alarm, audible alarm, or voice prompt.

The Powerheart includes the following basic components: 

- -    RHYTHM ANALYSIS SYSTEM - This system assesses the patient's
     electrocardiogram ("ECG") signal to determine when therapy is appropriate
     based upon parameters set by the patient's physician. ECG signals are
     sensed by electrodes placed on the patient's chest. This signal is
     amplified and filtered by an electrical analog circuit, digitized, and then
     analyzed by proprietary software algorithms in the device, which makes the
     determination of when therapy (a defibrillation shock) is appropriate for
     the patient.

- -    DEFIBRILLATOR - The AECD system uses electrical circuitry that provides an
     AAMI standard waveform for defibrillation. Such waveforms are used by a
     majority of defibrillators on the market, and have the longest proven track
     record of success. The AECD can be programmed to transmit the low amounts
     of electrical energy to the heart needed to terminate the life-threatening
     arrhythmia. The AECD is designed to provide progressively greater amounts
     energy, if needed, to restore the patient's heart to its normal cardiac
     rhythm. The maximum energy that can be delivered by the device is 360
     joules, which is the maximum limit recommended by the American Heart
     Association (AHA).

- -    DEFIBRILLATION ELECTRODES - The AECD uses self-adhesive, disposable
     defibrillation electrodes manufactured by a third party vendor to the
     Company's specifications. Electrodes require daily replacement.

- -    DATA STORAGE - The device stores real-time ECG data on a real-time basis in
     digital form. In addition, a strip chart recorder automatically prints
     real-time ECG and relevant device data during significant detected events.

- -    USER INTERFACE - Operating modes and setting parameters for rhythm analysis
     are programmed via the user interface. The bedside AECD has a liquid
     crystal display that indicates real time patient ECG as well as device
     settings.

- -    DATA RETRIEVAL SOFTWARE - This software is used to access the data stored
     from the AECD device. This software runs on a personal computer. The data
     can be viewed on a monitor and printed on a standard high-resolution
     printer. This provides valuable post-facto analysis of the patient's rhythm
     and device operation.

2.   ANALYZER AND ALGORITHM OVERVIEW

The Powerheart's analysis of a patient's rhythm begins with the detection of 
electrical activity in the heart.  Under normal conditions this event is an 
R-wave and represents a normal contraction of the heart.  In abnormal 
conditions this event may be the electrical signal generated with ventricular 
tachycardia or fibrillation.  The incoming signal is sampled every 2 
milliseconds (2/1000th of a second).  This incoming signal is filtered (for 
signal and motion noise as well as baseline wandering), differentiated and 
squared (calculations that normalize the event) and clipped (to take out 
excess signal).  The detection software for these electrical events also 
automatically adjusts to take into account the size characteristics of the 
preceding beats. If this moving average exceeds a given 

                                                                            2
<PAGE>

threshold, an electrical event (e.g. an R-wave) is considered to have 
occurred.  This further eliminates signal artifacts. 

Analysis continues by determining the rate at which these electrical events 
occur.  The Powerheart will measure the interval between consecutive events 
to compute rate.  This rate calculation is the primary parameter in 
determining if a rhythm is shockable.  This rate is called the Shockable 
Tachyarrhythmia Detection (STD) rate or simply the detection rate.  This rate 
analysis occurs continuously as a moving average.

In addition to rate analysis, the Powerheart is capable of distinguishing 
between unusually fast "normal" rhythms (tachycardia, supraventricular 
tachycardia or atrial fibrillation) and rhythms requiring a shock 
(ventricular tachyarrhythmias).  This feature is called Modulation Domain 
Function, or MDF-Registered Trademark-. MDF uses sophisticated morphology 
differentiation techniques designed to reduce the probability of delivering 
therapy for rapid normal rhythms that satisfy the rate criteria without 
compromising sensitivity in shocking ventricular tachycardia or fibrillation..

When the Powerheart is ready to deliver a shock, it will first verify that 
the defibrillation pads are properly attached to the patient, can safely 
deliver the shock and that the rhythm is still shockable.  If the 
life-threatening rhythm has changed on its own and no longer requires a 
shock, the Powerheart will safely dispose of the charge internally.  After 
the shock is delivered, the Powerheart will quickly re-acquire the ECG signal 
and resume analysis to check the resulting rhythm.  If the life-threatening 
rhythm continues, the Powerheart will charge and deliver another shock, if 
programmed.  If the shock restores normal rhythm, the Powerheart will wait 
for one minute then reset to the beginning of its therapy sequence.  Should 
the shock.

There are two special rhythms that must be taken abnormal rhythm recur during 
this minute, the Powerheart will continue therapy with the next programmed 
into account by any automatic defibrillator.  These rhythms occur when there 
is no ECG signal or when the patient is in Fine VF. When this situation 
occurs in a normal rhythm, this is called Asystole.  Shocking Asystole cannot 
help, and may in fact be harmful.

The Powerheart will not shock Asystole in accordance with the American Heart 
Association recommendations. Fine VF however, is detectable by the 
Powerheart, and the Powerheart will shock this rhythm.

The Powerheart incorporates important safety features and performs periodic 
internal diagnostics to verify it is correctly operating.  As already 
mentioned, the Powerheart will verify that the rhythm is shockable, just 
before delivering the shock.  In addition, the Powerheart is able to 
determine if the ECG and/or defibrillation electrodes become disconnected.  
The Powerheart is also able to determine if the ECG signal it is receiving is 
too small or too large for safe analysis.  In any of these situations occur, 
the Powerheart will alert the medical personnel to correct the situation.

                                                                            3

3.   PROGRAMMING OVERVIEW 

The Powerheart can be programmed for several modes of operation.  The first 
mode of operation is MANUAL.  In this mode, the Powerheart functions as a 
manual defibrillator.  The operator selects the shock energy, charges the 
device, and manually delivers the shock. MANUAL mode can always be selected 
by the operator. This allows the users to operate the Powerheart as a 
standard defibrillator, pre-empt automatic therapy or abort automatic therapy.

In order to set up the Powerheart for automatic use, a PROGRAMMING mode is 
available.  In this mode, the operator can program up to eight shocks.  The 
strength of the shock and a timed delay for the shock must be programmed for 
each therapy.  The shock strength can be programmed to "industry standard" 
energy selections from 5 to 360 Joules.  The delay indicates the time 
interval from the detection of the shockable rhythm until the delivery of the 
shock.  The delay may be programmed from 10 seconds to 10 minutes.  The 
ability to program a long delay allows the doctor to take into account those 
patients that can tolerate certain types of ventricular tachycardia.

The detection criteria are also set in PROGRAMMING mode.  The operator 
selects the ECG channel to be used for analysis.  The operator must also 
program the Shockable Tachyarrhythmia Detection (STD) rate described earlier. 
The STD rate may be programmed from 120 up to 240 beats per minute in steps 
of 5.  If MDF is enabled, then a rate must be set for it.  The rate for MDF 
is programmed to a value greater than the STD rate up to 240 beats per 
minute, again in steps of 5. Finally, the operator is able to enter a patient 
ID, date and time.

During the programming process, the Powerheart checks for unsafe conditions 
such as a delay without a corresponding shock or selection of an ECG channel 
that has not been attached to the patient.  The operator cannot continue 
until these conditions have been corrected.  Once programming is complete, 
the Powerheart will verify that the ECG signal is satisfactory for safe 
analysis and that the patient is in a normal rhythm.

The operator may now select one of two automatic analysis modes.  In the 
first mode, AUTO mode, the Powerheart will perform rhythm analysis and 
automatically deliver therapy when needed.  This is the primary intended mode 
of operation for the Powerheart.  A secondary mode called ADVISORY mode is 
also available.  In ADVISORY mode, the Powerheart will provide the automatic 
analysis and will automatically prepare to shock a shockable rhythm.  
However, the operator must confirm the shock before it will be delivered to 
the patient.

4.   CLINICAL RESULTS

To test the safety and efficacy of the Powerheart, a multi-center clinical 
trial study was conducted. 155 patients enrolled in four institutions. Of 
these patients, 130 were attached to the Powerheart and 25 were utilized as 
controls. The control patients allowed comparison of the Powerheart to 
standard medical care.  The Powerheart was utilized for over 1200 hours 
during this study.

                                                                            4
<PAGE>

Patients in the clinical trial experienced a total of 92 shockable episodes. 
The study found that the Powerheart had a sensitivity of 100% (correctly 
identifying shockable episodes), a specificity of 99.4 percent, (not allowing 
a non-shockable rhythm to be shocked). The average response time for the 
Powerheart was approximately 21 seconds.  In addition, normal rhythm was 
restored by the FIRST shock of the Powerheart in 96 percent of the actual 
shocks delivered with energy levels as low as 50 joules.

These results demonstrate that the Powerheart responded to every shockable 
event within seconds, successfully restored a normal rhythm and delivered 
shocks only when appropriate, confirming its safe to use.

QUALITY ASSURANCE PROGRAM.  Cardiac Science shall maintain a Quality 
Assurance Program that effectively ensures the quality of design, materials, 
workmanship, assembly, testing, inspection, distribution, and product support 
of all Products.

AUDIT RIGHTS.  Cardiac Science agrees to grant Physio complete and free 
access to verbal, visual, and written records, as well as access to 
personnel, suppliers, and facilities that are necessary and expeditious to 
Physio's confirmation of the Quality Assurance Program.  Physio shall perform 
audits of Cardiac Science's facility at approximately twelve (12) month 
intervals, and will give at least twenty (20) days notice of intent to visit 
Cardiac Science's facility for the purpose of carrying out an audit.  More 
frequent audits could occur as a result of investigations or corrective 
action follow-up.  These are likely to be less comprehensive, and, as a 
function of the nature and severity of the issue, notice for the audit could 
be much shorter -- as little as one day.

If Cardiac Science has asked any third party (for example, certifying bodies 
for ISO9001 registration) to audit their facility, Cardiac Science will 
inform Physio of such scheduled audits.  Physio may request Cardiac Science 
to direct the third party to audit certain areas of Cardiac Science's 
facility, and if such request results in additional third party audit expense 
to Cardiac Science, Physio shall reimburse Cardiac Science for such expense.  
Cardiac Science shall provide Physio with copies of third party audit 
reports.  Cardiac Science may edit such reports before sending them to Physio 
to remove any information which if transferred to Physio might be in conflict 
with Cardiac Science's existing confidentiality agreements with other parties.

CORRECTIVE ACTION SYSTEM.  To address Product quality issues, Cardiac Science 
shall implement and maintain a corrective action system to be approved by 
Physio.  This system shall specifically cover how Cardiac Science will deal 
with "trigger" events, such events being defined as the discovery of a 
problem by either Physio or Cardiac Science that has the potential of 
existing in Product that has already been shipped to Physio or has potential 
to disrupt deliveries. The Cardiac Science's corrective action system shall 
include the following:

     -Method of assessing risk in Cardiac Science's finished goods inventory 
(FGI), Physio's FGI, and distributed Product

     -Procedure for carrying out, validating, and documenting problem root 
cause analysis

     -Procedure for implementing remedial (short-term) corrective actions

     -Procedure for implementing permanent corrective action that address the 
root cause

     -Response time requirements that are compatible with Physio's corrective 
action system requirements
