PART I

ITEM 1. BUSINESS

The Company

Endocardial Solutions, Inc. ("ESI" or the "Company") designs, develops, and manufactures a minimally invasive diagnostic system that diagnoses, within the
span of a few heartbeats, potentially fatal abnormal heart rhythms known as arrhythmias. Arrhythmias are caused by irregular electrical activity in the heart that disrupts the heart's normal pumping
action. Arrhythmias characterized by an abnormally fast heart rate are known as tachycardias, which can appear in various forms. Ventricular tachycardia ("VT") occurs in the lower two chambers of the
heart and frequently lead to serious complications, including sudden cardiac death. Supraventricular tachycardia ("SVT"), including atrial tachycardia, atrial fibrillation and flutter, originates in
the upper two chambers of the heart and often result in chest pain, fatigue and dizziness and, while generally not life-threatening, are a leading cause of stroke in the United States.

To
date, electrophysiologists have generally been unable to adequately diagnose complex arrhythmias due to the limited capabilities of current technology. The Company believes that its
proprietary EnSite® catheter and Ensite 3000® clinical workstation (together, the "EnSite System") is a powerful new diagnostic tool that enables electrophysiologists to
rapidly and precisely locate the multiple, unpredictable points of origin of complex arrhythmias and improve the selection of patient treatment options. The EnSite System applies proprietary
mathematical algorithms to compute more than 3,000 points of electrical activity within a heart chamber, producing a high resolution, real-time, three-dimensional color display of the
electrical activity in the heart chamber. The "virtual electrogram" function of the EnSite System allows electrophysiologists to instantly view the electrical activity at any of the more than 3,000
points. The EnSite System is also capable of tracking and displaying the location and movements of auxiliary catheters introduced into the chamber.

In
1998, ESI received the necessary approval to market the EnSite System in the European Community for use in the right atrium and left ventricle of the heart. Distribution of the EnSite
System in Europe began in the second quarter of 1998. In 1999, ESI received clearance from the U.S. Food and Drug Administration (the "FDA") to market the EnSite System in the U.S. for diagnosis of
complex arrhythmias in the right atrium of the heart, and the Company continues to work with the FDA for the purpose of extending their marketing approval to the other chambers of the heart. ESI
received general approval to market the EnSite System for cardiac mapping in Australia, Korea, Thailand, Malaysia and Hong Kong in 2000, and in China and Taiwan in 2001. An exclusive distribution
arrangement with Nihon Kohden, one of Japan's leading manufacturers, developers and distributors of medical electronic products, was established in 2001, and distribution will commence pending
regulatory approval.

The
Company's strategy is to establish the EnSite System as the leading diagnostic tool for diagnosing arrhythmias in the more than 1,200 electrophysiology laboratories worldwide. The
EnSite System represents a new technology for mapping arrhythmias. The Company believes that the patient population that suffers from complex arrhythmias that are difficult to map using currently
available technology presents a significant market opportunity for the Company's EnSite System. The key elements of the Company's strategy are as follows:

The
Company intends to continue to focus on the ability of its technology to provide improved speed, increased accuracy and cost-effectiveness in mapping other arrhythmias.
This improved mapping power should benefit electrophysiologists in performing diagnostic procedures and prescribing treatments for an expanded patient population. In January 1998, the Company
signed a license agreement with Medtronic, Inc. which gives the Company co-exclusive use of 3D intracardiac location technology for its EnSite System. Integration of the technology
with the EnSite System is still under review, but the Company believes it will improve intracardiac catheter positioning while significantly reducing the use of harmful radiation. In
October 2001, the Company received FDA clearance for the Company's release of its Precision software, an upgraded version of the software used in the EnSite System that provides
more realistic heart chamber geometry and new catheter positioning techniques designed to improve orientation, speed up procedure times and reduce the use of fluoroscopy.

In
the first quarter of 1999, the Company announced a financing agreement with Medtronic, Inc. Under the agreement, the Company received $7 million from Medtronic Asset
Management. This loan was repaid in February 2001. In July 1999, the Company received proceeds of $10,000,000 in a private placement of 1,111,111 shares of its common stock to accredited
investors. In June 2000, the Company

3

received proceeds of $12,687,500 in a private placement of 2,030,000 shares of its common stock to accredited investors. In March 2001, the Company received proceeds of $7,349,000 in a private
placement of 2,449,666 shares of its common stock to accredited investors. In February 2002, the Company received proceeds of $10,000,000 in a private placement of 1,666,667 shares of its
common stock to accredited investors. Proceeds from this most recent sale of shares are being used for general working capital including expenses associated with new product development.

The
Company was incorporated in Minnesota in 1992 and was reincorporated in Delaware in 1995. The Company's common stock began trading on The Nasdaq National Market under the symbol
"ECSI" on March 19, 1997. The Company's world corporate headquarters are located at 1350 Energy Lane, Suite 110, St. Paul, Minnesota 55108, and its telephone number is

Background

The heart consists of four chambers: the ventricles, the lower two chambers, and the atria, the upper two chambers. A normal heartbeat is the result of electrical
impulses generated at the sinoatrial node, the heart's natural pacemaker located near the top of the right atrium. These impulses form a wave of electrical activation that travels down the
atria, causing them to contract and fill the ventricles, the heart's primary pumping chambers, with blood. After a brief delay in the atrioventricular node, located between the chambers, the
electrical activation wave enters the ventricles and produces a coordinated contraction of the ventricles that pump blood throughout the body's circulatory system.

When
defects in the heart tissue interfere with the normal formation or conduction of the heart's electrical activity, abnormal heart rhythms, known as cardiac arrhythmias, develop.
Cardiac arrhythmias have numerous causes, including congenital defects, tissue damage due to heart attacks or arteriosclerosis (the deposition of fatty substances in the inner layer of the arteries)
and other diseases, that accelerate, delay or redirect the transmission of electrical activity, thereby disrupting the normal coordinated contractions of the chambers. Arrhythmias characterized by an
abnormally fast heart rate (more than 100 beats per minute) are known as tachycardia.



Characteristics of Ventricular Tachycardias.Ventricular tachycardia, which afflicts approximately one million Americans, is
a potentially life-threatening condition caused either by abnormally rapid impulse formation or by slow ventricular conduction which interferes with the heart's normal electrical activity
and causes abnormally frequent contractions of the ventricles. Rapid ventricular contractions often result in significantly reduced cardiac output due to inefficient blood pumping. As a result, the
body receives an inadequate supply of oxygen, which can cause dizziness, unconsciousness, cardiac arrest and death. VT conditions tend to become more serious over time. Individuals with VT are at risk
of imminent death due to its unpredictable nature.

Many
VT result from heart attacks caused by coronary artery disease. When a heart attack occurs due to a blockage in one or more coronary arteries, a portion of the heart muscle (most
often in the left ventricle) dies. As a result, irregular borders consisting of intermixed healthy and scar tissue are formed and VT typically originate at these sites. As the average age of the U.S.
population increases, it is expected that the number of persons who suffer heart attacks and are at risk of VT will also increase.

VT
is a highly complex and transient form of cardiac arrhythmia, that varies significantly from patient to patient. A small percentage of ventricular tachycardia patients have simple
forms of the disease, which are focused on a single anatomic site within the ventricle. The Company estimates, however, that of the one million patients that suffer from VT, the majority suffer from
complex VTs that (i) have multiple sites

4

---

of aberrant electrical activity, (ii) prevent sufficient cardiac output, making them dangerous to induce in the patient (which is required for diagnosis) and (iii) are nonsustained and,
consequently, are only detectable for several heartbeats.

Diagnosing Ventricular Tachycardia.Patients suspected of suffering from VT are initially screened by a cardiologist by means
of external cardiac monitoring, typically in the form of an electrocardiogram or Holter recording, which captures electrical activity from surface leads placed on the patient's chest for
24 hours. When further testing is warranted, the patient is referred to a cardiac electrophysiologist for a cardiac electrophysiology ("EP") study.

An
EP study evaluates the electrical integrity of the heart by stimulating multiple intra-cardiac sites and recording the electrical response. During an EP study a patient's clinical
tachycardia is induced in a controlled setting in order to diagnose the tachycardia and select an appropriate treatment or combination of treatments. EP studies using currently available technology
are lengthy and tedious procedures, which consist of probing the interior of the left ventricle with single-point contact catheters, causing significant discomfort for the patient. In order to analyze
the information generated by single-point contact catheters for the purpose of prescribing treatment, electrophysiologists review the signals measured by these catheters as multiple rows of waveforms
displayed on a computer screen. Two or more catheters are often used to provide more information to the electrophysiologist and thereby aid in identifying the sites of origin of tachycardia. The
electrophysiologist generally constructs a mental image of the sites of the VT within the heart's chamber by calculating the relative timing of electrical activation among the waveforms displayed on
the computer screen. The electrophysiologist then estimates the site or sites of origin (which correspond to the physical positions of the catheters) through two-dimensional fluoroscopic
(x-ray) projections. As the tachycardia becomes more complex, the electrophysiologist's reconstruction of the heart's electrical activity and location of the sites of origin becomes more
difficult.

The
limited number of patients suffering from simple forms of VT have been effectively diagnosed using existing single-point contact catheter technology with diagnostic procedures that
can be time consuming, tedious and invasive. However, single-point contact catheters have limited utility in diagnosing complex ventricular tachycardia, including those that are
hemo-dynamically ill-tolerated or short in duration. The limited data produced in point-by-point mapping often does not provide the electrophysiologist
with sufficient diagnostic power for a complete understanding of the ventricular tachycardia. Moreover, when attempted, diagnosing complex ventricular tachycardia with single-point, contact catheters
can take from six to twelve hours and requires significant use of fluoroscopy to guide the catheter, which exposes both the patient and the medical staff to radiation.

In
an effort to address the diagnostic shortcomings of single-point contact catheters, there are currently under development several "basket" contact catheters measuring multiple points
of electrical activity simultaneously. These basket catheters will require contact with the heart's surface for measurement of electrical activity, and the Company believes that these catheters will
suffer from many of the shortcomings of single-point contact catheters.

Treatments Following Diagnosis of Ventricular Tachycardia.The Company's EnSite System is designed for the diagnosis of
tachycardia. The Company does not currently design products for the treatment of this disease. However, the Company believes that the EnSite System will provide electrophysiologists with a diagnostic
tool to improve their ability to select among available tachycardia treatment options.

Once
a patient's VT is diagnosed, the electrophysiologist chooses among the various treatment options available. Noncurative treatments include antiarrhythmic drugs and implantable
defibrillators, both of which attempt to ameliorate the patient's condition and reduce the risks associated with the VT but do not eliminate the cause of the tachycardia. Historically, the only
curative treatment available for VT was open heart surgery, but it has been rarely used due to its high morbidity and mortality. More recently, however, catheter ablation, a potentially curative
treatment currently under development, has been used in

5

---

a limited number of cases for complex VT Often electrophysiologists prescribe a combination of drugs, defibrillators and ablation for the treatment of VT.

Antiarrhythmic
drugs, which are prescribed to chemically suppress the arrhythmic activity, have to date been the most common treatment of VT Antiarrhythmic drugs are not curative and can
result in considerable side effects limiting the effectiveness of the drugs and the ability of patients to use them over long periods of time.

Automatic
implantable cardioverter defibrillators ("ICDs"), which detect and stop a tachycardia once it has started by pacing or by applying high energy pulses, have also become a common
treatment for VT The useful life of an ICD is approximately five to seven years, at the end of which time the ICD is
generally replaced in another surgical procedure. Many ICD patients also receive antiarrhythmic drug therapy in an attempt to minimize the frequency of VT episodes.

There
is increasing interest in the United States and Europe in using catheter ablation to treat VT Catheter ablation is a minimally invasive and potentially curative treatment in which
a high radio frequency current is emitted from a catheter guided to the heart through a vein in the neck or groin to selectively destroy the heart tissue responsible for the abnormal electrical
activity. The use of catheter ablation to date has been limited due to the inability of single-point contact catheters to effectively map complex VT cases. Although catheter ablation is not yet
commonly prescribed to treat VT and the devices have not yet been approved by the FDA for marketing in the United States for treatment of VT, it is the subject of increasing technological research and
development. The Company believes catheter ablation could become a more commonly used treatment for VT with advances in diagnostic technology such as that being developed by the Company.



Approximately three million of the four million people in the United States who suffer from tachycardia have some form of SVT Supraventricular tachycardia is an
abnormally rapid beating of the atria which may reduce the amount of blood pumped into the ventricles, and, consequently, from the ventricles to the rest of the body. Although SVT can be debilitating,
causing chest palpitations, fatigue and dizziness, it is generally not life-threatening. The principal types of SVT are Wolff-Parkinson-White syndrome ("WPW"), Atrioventricular Nodal
Re-entrant Tachycardia ("AVNRT"), and atrial fibrillation, atrial flutter, and atrial tachycardia.

Approximately
one million people in the United States suffer from WPW or AVNRT The tachycardia associated with WPW and AVNRT are generally easy to diagnose and locate due to their more
simple, single-site nature and predictable location within the atria. WPW and AVNRT have been effectively treated by catheter ablation with available contact catheters.

Approximately
two million people in the United States suffer from atrial fibrillation or atrial flutter. Atrial fibrillation is the most common type of sustained arrhythmia and is
characterized by a disorganized and chaotic conduction of electrical activation, causing the heart's upper chambers to quiver-sometimes as fast as 600 to 1,000 beats per minute, which results in
ineffective pumping of the atria. Under these conditions, blood tends to pool and clot, increasing the risk of stroke. The American Heart Association estimates that approximately fifteen percent of
all strokes in the United States are caused by atrial fibrillation. The incidence of atrial fibrillation is linked to aging and thus is expected to increase as the average age of the United States
population increases.

Typically,
diagnosis of atrial fibrillation is easily discerned through an electrocardiogram recording. Beyond initial detection, electrophysiologists have had limited success in mapping
atrial fibrillation using current
single-point technology due to its highly complex and chaotic nature. The inability to effectively map and understand the origins of atrial fibrillation has hindered the development of treatments for
the disease.

6

---

Antiarrhythmic
drugs and anticoagulation therapy are the most commonly prescribed treatments for atrial fibrillation, but they are not curative and have undesirable side effects. The
only known curative treatment for atrial fibrillation is a costly and rarely performed open heart surgical procedure known as the surgical maze procedure. The incisions made in this surgery
electrically isolate the atria into regions that can no longer maintain fibrillation. In addition, an atrial defibrillator is under development for detecting and controlling atrial fibrillation with
low energy shocks.

Catheters
have been approved for ablation treatments in the atria; however, due to the limited understanding of atrial fibrillation, to date they have not proven effective. Catheters are
under development for potentially curative ablation of atrial fibrillation. One type of catheter under development is designed to create linear lesions along the interior wall of the atrium to
electrically isolate regions of the chamber in a manner similar to the surgical maze procedure. Other emerging methods are aimed at more localized ablation treatment based on a hypothesis that atrial
fibrillation is maintained in an electrically localized region of the chamber, requiring detailed mapping.

The
Company believes that the complexity of atrial fibrillation and the search for effective and curative treatments, including catheter ablation, will require a diagnostic mapping
technology that provides much greater resolution and diagnostic capabilities than currently available technology. In January 2001, the Company received FDA approval for the use of the EnSite
System in the left atrium in a multi-center clinical study for diagnosing arrhythmias including atrial fibrillation, which the Company began in the second quarter of 2001.

The EnSite System

The Company has developed and continues to enhance its proprietary EnSite System to address the need for more rapid, comprehensive and cost-effective
diagnosis of complex forms of arrhythmia. The high resolution, three-dimensional, color display generated by the EnSite System is designed to provide electrophysiologists greater diagnostic
capabilities than single-point contact catheter mapping devices currently available. The EnSite System provides electrophysiologists with a real time, virtual image of the electrical activity of the
heart without contacting the heart's surface. The EnSite System displays more than 3,000 points of electrical activity using the Company's proprietary algorithms. Diagnosis is enhanced by the "virtual
electrogram" function of the EnSite System workstation that allows electrophysiologists to instantaneously view the electrical activity at any of the more than 3,000 points displayed by selecting a
specified point on the workstation's three-dimensional color map of the heart with the workstation's mouse pointer. In addition, the locator function of the EnSite System workstation also enhances
diagnosis and treatment by providing electrophysiologists with real-time feedback as to the precise location of auxiliary and therapy catheters introduced into the heart.

The
Company's EnSite System consists of the EnSite catheter and clinical workstation that together form an integrated system. The EnSite System is designed to map ventricular and atrial
arrhythmia.



The EnSite catheter is a non-contact, single-use, multi-electrode array, and percutaneous catheter, designed for use with the EnSite
clinical workstation. The EnSite catheter's multi-electrode array senses electrical activity generated from the endocardial wall while positioned in the heart chamber. The array area of the EnSite
catheter is comprised of an inflatable polyurethane balloon within a mechanically expandable multi-electrode array. The multi-electrode array contains a wire braid consisting of 64 braided wires. A
handle and cable connector are located at the proximal end of the catheter to allow the physician to position the distal end of the catheter, deploy the multi-electrode array and make electrical
connection from the array to the patient interface unit of the EnSite System's workstation.

The
EnSite catheter is inserted percutaneously over a standard guidewire into a selected chamber of the heart. When positioned, the wire braid is mechanically expanded and the balloon
residing under the

7

---

wire braid in the array area of the catheter is inflated with a radiopaque solution to form an ellipsoidal, multi-electrode array. When deployed, the array is small enough to permit the normal
functioning of the heart. In addition to the EnSite catheter, a standard single-point diagnostic catheter is inserted in a chamber of the heart in order to facilitate establishing the chamber's
spatial boundaries. The multi-electrode braid array collects data used to compute more than 3,000 points of the heart chamber's electrical activity in the span of a few heartbeats by gathering a large
amount of the electrical conduction information from the entire chamber and transmitting this information through the wire braid back down the catheter shaft to the EnSite System's clinical
workstation.



The EnSite System's clinical workstation consists of the Company's proprietary patient interface unit and a Silicon Graphics-based workstation and other
third-party peripherals, such as a color monitor, a printer and an optical disk drive. The patient interface unit is designed to amplify and digitize the electrical information transmitted by the
EnSite catheter. The patient interface unit also accepts information generated by other auxiliary sensors, including as many as 32 standard contact catheter electrodes, which allows the
electrophysiologist to monitor clinical events or capture additional data for simultaneous display on the workstation. The workstation is programmed with software containing the Company's proprietary
algorithms, which process the electrical information transmitted by the EnSite catheter and reconstruct the heart's geometric layout and the distribution of electrical activity. The heart and the
electrical activity are displayed on the workstation as high resolution, three-dimensional
isopotential or isochronal color maps. The maps can be viewed as a snapshot in time or as an animated playback at adjustable rates of speed. The maps can also be viewed from any perspective in space
and may be zoomed in and out to facilitate rapid diagnosis and treatment of the tachycardia, including identifying the optimal site or sites for ablation.

The
electrical activity displayed on the workstation's three-dimensional map can also be displayed as time-waveforms, called "Virtual Electrograms," at multiple selected
sites on the endocardium. Virtual Electrograms are produced by the Company's software contained in the workstation. The electrophysiologist can instantaneously select any of the more than 3,000 sites
and waveforms to be displayed by pointing and clicking with the workstation's mouse pointer at the desired location on the map of the heart. The Virtual Electrogram function provides the equivalent of
positioning a standard contact catheter at the same site on the endocardium-but without the need for actual physical contact.

The
EnSite System's workstation also generates the EnGuide locator signal that can be emitted from selected electrodes on standard EP catheters introduced into the heart
along with the EnSite catheter. The EnGuide locator signal provides electrophysiologists with an interactive method for locating and positioning auxiliary or therapy catheters. The locator function is
designed to allow electrophysiologists to diagnose and treat complex tachycardia with significantly less use of fluoroscopy than is currently required when using presently available single-point
contact catheters. The EnGuide locator signal is detected and displayed on the workstation's three-dimensional map to provide real-time feedback to the electrophysiologist as to the
precise location of the catheter and to assist in guiding the catheter (or catheters) to a specific site on the endocardium.

The
EnSite System is designed to function as a complete, integrated electrophysiology laboratory system to provide a wide range of accurate and versatile diagnostic tools in one product.
In addition to displaying high resolution, graphical, three-dimensional maps, the EnSite System provides multi-channel recording from standard EP electrode catheters and standard waveform displays. In
the second quarter of 2000, the Company released Clarity, an upgraded version of the Company's software product for use in the EnSite System that offers a more simplified user interface
and increased automation of arrhythmia analysis. The Clarity software is designed to simplify use of the EnSite System and reduce training time for hospital staff. In October 2001, the Company
received FDA clearance for the Company's release of its Precision software, an upgraded version of the software used in the EnSite System that provides more

8

realistic heart chamber geometry and new catheter positioning techniques designed to improve orientation, speed up procedure times and reduce the use of fluoroscopy. The Company intends to develop
and market periodic software upgrades and new applications for use with the EnSite System.

Research and Development

To date, the Company's primary activity has been research, development and testing of the EnSite catheter and the clinical workstation. Virtually all of the
Company's research and development activity is performed internally by the Company's team of scientists, engineers and technicians, in consultation
with the Company's outside consultants. The Company's research and development team is divided among five groups: software engineering, applied research, hardware engineering, verification and
validation, and catheter engineering. In addition, various members of the research and development team support the design and development of the manufacturing processes used in fabricating the
Company's products.

Among
its research and development goals, the Company is now pursuing the optimization of the EnSite System functionality for future software releases, incorporating location technology
for use in conventional EP studies and developing new catheter technologies for reduced size and cost. The Company expects that its future research and development objectives will include developing
new mapping and catheter configurations and software upgrades to enhance the capabilities and ease-of-use of the EnSite System as well as supporting the Company's manufacturing
personnel in refining manufacturing processes, improvements and scale-up in connection with the commercialization of the EnSite System. The Company incurred research and development
expenses of approximately $5.1 million, $4.4 million and $5.3 million for the fiscal years ended December 31, 1999, 2000 and 2001, respectively. The Company anticipates
that it will continue to make significant investments in research and development.

Manufacturing

The Company manufactures its EnSite catheters in its 3,200 square foot clean-room facility at its world corporate headquarters in St. Paul, Minnesota.
During the second quarter of 2002 the Company will complete construction on an additional 1,700 square feet of clean-room space which will approximately double the existing production
capacity for the EnSite catheter. The Company also performs final assembly and system level testing of all hardware and software components for the EnSite System clinical workstation at this facility.

The
manufacturing process for the EnSite catheter involves a number of steps and component parts. The Company assembles and tests each catheter individually prior to packaging and
sterilization, which it conducts in accordance with the requirements of the FDA. The Company has designed its manufacturing processes to utilize automation to the extent appropriate in order to
increase production volume and reduce costs.

The
manufacturing of the EnSite System clinical workstation, including the patient interface unit, involves the assembly, integration and testing of components purchased from third
parties. The Company purchases the basic computer workstation from Silicon Graphics, and ESI software engineers program the workstation with its proprietary software, including advanced mathematical
algorithms.

The
Company purchases the raw materials and various component parts for the EnSite System from a number of suppliers. The Company has adopted rigorous quality control measures to ensure
that the component parts it purchases meet its specifications and standards. Certain of the components are purchased from sole source suppliers, including the computer workstation. There are
relatively few
alternative sources of supply for these components, and it may be difficult for the Company to locate additional suppliers for these components.

9

---

The
Company has implemented a manufacturing quality program designed to meet all domestic and international standards for manufacturing medical devices. The Company is required to meet
the requirements of the FDAs good manufacturing practices ("GMP") in order to distribute its products in the United States, and the requirements for ISO 9001 and CE Mark certification in order to
continue to distribute products in Europe. During the fourth quarter 2001, the Company passed a FDA inspection of the facility and the manufacturing processes. The Company received ISO 9001
certification for its catheter and quality system in August 1997, and ISO 9002 certification for the clinical work station and a CE Mark for each of the EnSite catheter and the EnSite 3000
clinical workstation in the first quarter of 1998. ISO 9001 certification for our workstation was subsequently received in November 1998. As part of the regulatory requirements, the Company's
facilities and manufacturing processes will be subject to inspection and audit. If the Company fails to satisfy the GMP requirements, it may be required to alter its manufacturing processes. Moreover,
any such failure could have a material adverse effect on the Company's ability to market its products, which could adversely affect its business and results of operations. The Company's suppliers will
also be required to satisfy GMP standards.

Sales and Marketing

In the first quarter of 1998, the Company received a CE Mark for each of the Ensite catheter and the Ensite 3000 clinical workstation, allowing the Company to
begin marketing its products in the European Community for right atrial and left ventricular use. Distribution in Europe of the EnSite System and EnSite catheter began in the second quarter of 1998.
In the second quarter 1999, the Company received FDA approval to market the EnSite catheter and EnSite System for right atrial use in the United States. In 2000, the Company received general approval
to market the EnSite System for cardiac mapping in the following countries: Australia, Korea, Thailand and Taiwan. The Company has also begun marketing the EnSite System in Malaysia, Hong Kong and
Japan.

The
Company has employed a direct sales force in the United States and Europe, and uses distributors for certain international markets. In 2001, the Company ended an exclusive
distribution arrangement in Europe and Japan with Medtronic, Inc., but established an exclusive distribution arrangement in Japan with Nihon Kohden, one of Japan's leading manufacturers,
developers and distributors of medical electronic products. The Company intends to have additional distributors in various markets throughout the world. The Company retains all distribution rights in
the United States.

The
Company believes that prominent electrophysiology labs are generally more likely to keep abreast of and utilize new technologies such as the EnSite System for diagnosing and treating
tachycardia. After the Company establishes a presence in major medical centers housing such electrophysiology labs,
it then intends to broaden its sales and marketing efforts to include the growing number of smaller, community-based electrophysiology labs. As part of its strategy to gain the awareness of and
acceptance by electrophysiology laboratories, the Company has focused on and intends to continue to focus on developing peer reviewed journal articles authored by leading experts in electrophysiology,
sponsoring publication of papers based on research covering the performance and benefits of the EnSite System and conducting informational seminars. In addition, as part of its marketing program the
Company holds technical seminars and training sessions to educate physicians and its direct sales force and distributors in the use of the Company's products.

Patents and Proprietary Rights

The Company's success will depend in part on its ability to obtain patent protection for its products and processes, to preserve its trade secrets and to operate
without infringing or violating the proprietary rights of third parties. The Company actively pursues patent protection in the United States and foreign jurisdictions for each of the areas of
invention embodied in the EnSite System, and will actively pursue patent protection for proprietary aspects of its technology in the future. Currently, the Company has fifteen (15) U.S. patent
applications pending by which it is seeking to obtain protection for certain

10

---

enhancements currently embodied in the EnSite System, relating to the catheter, catheter localization techniques and user interface elements. Additionally, one U.S. patent application has been
allowed, with issuance expected with the year. The Company also has four issued U.S. patents, which relate to the technology underlying the EnSite System and development-stage versions of the system.
One of these patents covers the catheter of the EnSite System and its development-stage versions. The remaining three patents are directed to measurement methodologies used in the development-stage
versions of the EnSite System. The Company has also filed and has pending several foreign patent applications directed to various aspects of the technology underlying the EnSite System.

In
January 1998, the Company signed a license agreement with Medtronic, Inc. which gives the Company co-exclusive use of 3D intracardiac location technology for
its EnSite System. The license, as currently in use by the Company, is not royalty-bearing. A required royalty equal to 2% of net sales of licensed products only occurs if the Company is acquired by
one of the competitors of Medtronic named in the license agreement. ESI's right to use the technology for intracardiac mapping applications in the treatment of arrhythmias is co-exclusive
with Medtronic and its affiliates, and the license lasts until the patents on the technology expire beginning in 2015 unless extended. Integration of the technology with the EnSite System is still
under review but the Company believes it will improve intracardiac catheter positioning while significantly reducing the use of harmful radiation.

The
Company, like other firms that engage in the development and marketing of medical devices, must address issues and risks relating to patents and trade secrets. The coverage sought in
a patent application can be denied or significantly reduced before or after the patent is issued. Consequently there can be no assurance that any of the Company's pending or future U.S. or foreign
patent applications will result in issued patents, that the scope of any patent protection will exclude competitors or provide competitive advantages to the Company, that any of the Company's current
or future U.S. or foreign patents will not be challenged, circumvented by competitors or others or that such patents will be
found to be valid or sufficiently broad to protect the Company's technology. Since patent applications are secret until patents are issued in the United States or corresponding applications are
published in other countries, and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, the Company cannot be certain that it was the first to
make the inventions covered by each of its pending patent applications, or that it was the first to file patent applications for such inventions. In addition, there can be no assurance that
competitors, many of which have substantial resources and have made substantial investments in competing technologies, will not seek to apply for and obtain patents that will prevent, limit or
interfere with the Company's ability to make, use or sell its products either in the United States or in international markets. Further, the laws of certain foreign countries may not protect the
Company's intellectual property rights to the same extent as do the laws of the United States.

In
addition to patents, the Company relies on trade secrets and proprietary knowledge, which it seeks to protect, in part, through appropriate confidentiality and proprietary information
agreements. In particular, the Company relies upon such means to protect the proprietary software used in the EnSite System. The confidentiality and proprietary information agreements generally
provide that all confidential information developed or made known to individuals by the Company during the course of the relationship with the Company is to be kept confidential and not disclosed to
third parties, except in specific circumstances. The agreements also generally provide that all inventions conceived by the individual in the course of rendering services to the Company shall be the
exclusive property of the Company. There can be no assurance that proprietary information or confidentiality agreements with employees, consultants and others will not be breached, that the Company
will have adequate remedies for any breach, or that the Company's trade secrets will not otherwise become known to or independently developed by competitors.

There
has been substantial litigation regarding patent and other intellectual property rights in the medical device industry and companies in the medical device industry have employed
intellectual property litigation to gain a competitive advantage. There can be no assurance that the Company will not become subject to patent infringement claims or litigation in a court of law, or
interference proceedings declared by

11

---

the United States Patent and Trademark Office ("USPTO") to determine the priority of inventions or an opposition to a patent grant in a foreign jurisdiction. The defense and prosecution of
intellectual property suits, USPTO interference or opposition proceedings and related legal and administrative proceedings are both costly and time-consuming and could result in
substantial uncertainty to the Company. Litigation or regulatory proceedings, which could result in substantial cost and uncertainty to the Company, may also be necessary to enforce patent or other
intellectual property rights of the Company or to determine the scope and validity of other parties' proprietary rights. Any litigation, opposition or interference proceedings will result in
substantial expense to the Company and significant diversion of effort by the Company's technical and management personnel. There can be no assurance that the Company will have the financial resources
to defend its patents from infringement or claims of invalidity. An adverse determination in any litigation could subject the Company to significant liabilities to third parties, require the Company
to seek licenses from or pay royalties to third parties or prevent the Company from manufacturing, selling or using its proposed products, any of which could have a material adverse effect on the
Company's business and prospects. The Company is not currently a party to any patent or other litigation.

Competition

The Company believes that its competitive success will depend primarily upon its ability to demonstrate the clinical efficacy of the EnSite System; effectively
create market awareness and acceptance of the system while maintaining its proprietary nature; and manufacture and deliver the system on a timely basis. The tachycardia diagnostic mapping field of the
medical device industry has attracted a high level of interest both from companies with an established presence in the field of electrophysiology and from more recently formed companies. The Company's
competitors include companies that offer standard, single-point contact diagnostic catheters, and companies that offer multi-point, basket contact catheters for diagnosing tachycardia that use
multiple electrodes to provide more data points for the measurement of the heart's electrical activity. The Company is also aware of other medical device companies that are developing alternatives to
single-point contact catheter mapping technology.

The
Company believes that participants in the market for mapping tachycardia compete on the basis of clinical effectiveness, ease of use, cost and on the basis of acceptance by health
care professionals. Competition is also affected by the length of time required for products to be developed and receive regulatory approval. The medical device industry is characterized by rapid and
significant technological change. As a result, the Company's success will depend in part on its ability to respond quickly to medical and technological changes through the development and introduction
of new products.

Many
of the Company's competitors and potential competitors have substantially greater capital resources, research and development staffs and facilities than the Company. In addition,
most of the Company's competitors and potential competitors have substantially greater experience than the Company in researching and developing new products, testing products in clinical trials,
obtaining regulatory approvals and manufacturing and marketing medical devices. There can be no assurance that the Company will succeed in developing and marketing technologies and products that are
clinically more efficacious and cost-effective than the more established diagnostic products or the new approaches and products developed and marketed by its competitors. Moreover, there
can be no assurance that the Company will succeed in developing new technologies and products that are available prior to its competitors' products. The failure by the Company to demonstrate the
efficacy and cost-effective advantages of its products over those of its competitors could have a material adverse effect on the Company's business and results of operations.

Third-Party Reimbursement for the Company's Products

In the United States, health care providers, including hospitals and physicians, that purchase medical products for treatment of their patients generally rely on
third-party payors, principally federal Medicare, state Medicaid and private health insurance plans, to reimburse all or a part of the costs and fees

12

---

associated with the procedures performed using these products. The Company's success will be dependent upon, among other things, the ability of health care providers to obtain satisfactory
reimbursement from third-party payors for medical procedures in which the Company's products are used. Third-party
reimbursement will depend upon decisions by the Center for Medicare and Medicaid Services, as well as by individual health maintenance organizations and private insurers and other payors. Third-party
payors determine whether to reimburse for a particular procedure and, if so, will reimburse health care providers for medical treatment based on a variety of methods, including a lump sum prospective
payment system based on a diagnosis related group or per diem, a blend between the health care provider's reported costs and a fee schedule, a payment for all or a portion of charges deemed reasonable
and customary, or a negotiated per capita fixed payment. Specific to Medicare, the EnSite catheter is currently reimbursable under both inpatient and outpatient procedure scenarios. For inpatient
procedures, the EnSite procedure will most typically be reimbursed under Diagnosis Related Group 518. For outpatient procedures the EnSite catheter is eligible for separate reimbursement in addition
to the hospital's Ambulatory Payment Classification for cardiac 3-dimensional mapping. Third-party payors are increasingly challenging the pricing of medical products and procedures. Even if a
procedure is eligible for reimbursement, the level of reimbursement may not be adequate. Additionally, payors may deny reimbursement if they determine that the device used in the treatment was
unnecessary, inappropriate or not cost-effective, experimental or used for a non-approved indication.

The
Company's EnSite catheter is sold at a premium in comparison to existing single point catheters used in current diagnostic or mapping procedures and requires an initial capital
outlay for the companion clinical workstation. In addition to establishing the safety and efficacy of the EnSite System, and assuming no increase in the level of reimbursement for cardiovascular
procedures expected to utilize the Company's products, the Company may be required to economically justify the relative increased cost of utilizing the EnSite System by satisfactorily demonstrating
the enhanced benefits of the EnSite System to health care providers and payors in terms of such factors as enhanced patient procedural efficiencies, reduced radiation exposure and improved patient
outcomes.

Reimbursement
systems in international markets vary significantly by country and by region within some countries, and reimbursement approvals must be obtained on a
country-by-country basis. Many international markets have government managed health care systems that control reimbursement for new products and procedures. In most markets,
there are private insurance systems as well as government managed systems. Market acceptance of the Company's products will depend on the availability and level of reimbursement in international
markets targeted by the Company. There can be no assurance that the Company will obtain reimbursement in any country within a particular time, for a particular time, for a particular amount, or at
all.

The
Company believes that less invasive procedures generally provide less costly overall therapies as compared to conventional drug, surgery and other treatments. The Company anticipates
that hospital administrators and physicians would justify the use of the Company's products by the attendant cost savings and clinical benefits that the Company believes would be derived from the use
of its products. However, there can be no assurance that this will be the case. Accordingly, reimbursement for the Company's products may not be in international markets under either government or
private reimbursement systems, and health care providers may not advocate reimbursement for procedures using the Company's products. Failure by hospitals in the United States or in international
markets and other users of the Company's products to obtain reimbursement from third-party payors, or changes in government and private third-party payors' policies toward reimbursement for procedures
employing the Company's products, would have a material adverse effect on the Company's business, financial condition and results of operations. Moreover, the Company is unable to predict what
additional legislation or regulation, if any, relating to the health care industry or third-party coverage and reimbursement may be enacted in the future, or what effect such legislation or regulation
would have on the Company.

13

---

Political,
economic and regulatory influences are subjecting the health care industry in the United States to increased scrutiny. The Company anticipates that Congress, state
legislatures and the private sector will continue to review and assess alternative health care delivery and payment systems. Potential approaches that have been considered include mandated basic
health care benefits, controls on health care spending through limitations on the growth of private health insurance premiums and Medicare and Medicaid spending, greater reliance on prospective
payment systems, the creation of large insurance purchasing groups, price controls and other fundamental changes to the health care delivery system. Legislative debate is expected to continue in the
future, and market forces are expected to demand reduced costs. The Company cannot predict what impact the adoption of any federal or state health care reform measures, future private sector reform or
market forces may have on its business.

Government Regulation



The Company's EnSite System is regulated in the United States as a medical device by the FDA under the federal Food, Drug, and Cosmetic Act ("FDC Act") and
requires premarket approval by the FDA prior to commercialization. In addition, certain material changes or modifications to medical devices also are subject to FDA review and approval. Pursuant to
the FDC Act, the FDA regulates the research, testing, manufacture, safety, labeling, storage, record keeping, advertising, distribution and production of medical devices in the United States.
Noncompliance with applicable requirements can result in warning letters, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the
government to grant premarket approval for devices, and criminal prosecution.

Medical
devices are classified into one of three classes, Class I, II or III, on the basis of the controls deemed by the FDA to be necessary to reasonably ensure their safety and
effectiveness. Class I devices are subject to general controls (e.g., labeling and adherence to GMPs). Class II devices are subject to general controls and to special controls (e.g.,
performance standards, and premarket notification). Generally, Class III devices are those which must receive premarket approval by the FDA to ensure their safety and effectiveness (e.g.,
life-sustaining, life-supporting and implantable devices, or new devices which have not been found substantially equivalent to legally marketed devices), and require clinical
testing to ensure safety and effectiveness and FDA approval prior to marketing and distribution. The FDA also has the authority to require clinical testing of Class II devices.

If
human clinical trials of a device are required and if the device presents a "significant risk," the manufacturer or the distributor of the device is required to file an IDE
application prior to commencing human clinical trials. The IDE application must be supported by data, typically including the results of animal and, possibly, mechanical testing. If the IDE
application is approved by the FDA, human clinical trials may begin at a specific number of investigational sites with a maximum number of patients, as approved by the FDA. Sponsors of clinical trials
are permitted to sell those devices distributed in the course of the study provided such costs do not exceed recovery of the costs of manufacture, research, development and handling. The clinical
trials must be conducted under the auspices of an independent institutional review board ("IRB") established pursuant to FDA regulations.

The
FDC Act provides two basic review procedures for medical devices. Certain products may qualify for a submission authorized by Section 510(k) of the FDC Act, wherein the
manufacturer gives the FDA a premarket notification of the manufacturer's intention to commence marketing the product. The manufacturer must, among other things, establish that the product to be
marketed is substantially equivalent to another legally marketed product. Marketing may commence when the FDA issues a letter finding substantial equivalence. If a medical device does not qualify for
the 510(k) procedure, the manufacturer must file a premarket approval ("PMA") application. This procedure requires more extensive prefiling testing than the 510(k) procedure and involves a
significantly longer FDA review process.

14

---

A
PMA application must be supported by extensive data, including preclinical and clinical trial data, as well as extensive literature to prove the safety and effectiveness of the device.
Following receipt of a PMA application, if the FDA determines that the application is sufficiently complete to permit a substantive review, the FDA will "file" the application. Under the FDC Act, the
FDA has 180 days to review a PMA application, although the review of such an application more often occurs over a protracted time period, and generally takes approximately two years or more
from the date of filing to completion.

The
PMA application approval process can be expensive, uncertain and lengthy. A number of devices for which premarket approval has been sought have never been approved for marketing. The
review time is often significantly extended by the FDA, which may require more information or clarification of information already provided in the filing. During the review period, an advisory
committee likely will be convened to review and evaluate the application and provide recommendations to the FDA as to whether the device should be approved. In addition, the FDA will inspect the
manufacturing facility to ensure compliance with the FDA's GMP requirements prior to approval of an application. If granted, the approval of the PMA application may include significant limitations on
the indicated uses for which a product may be marketed.

The
Company conducted clinical trials of its EnSite System on patients with VT in the United Kingdom in late 1995, 1996 and 1997 under an authorization of the Medical Devices Agency
("the MDA") of the British government. The Company submitted its IDE application to the FDA in May 1996 based
on the results of the initial four patient trial plus extensive pre-clinical testing. Based on consultation with the FDA, and to further support its IDE submission, the Company conducted
nine additional ventricular patient trials and submitted this data in November 1996 in an amendment to the IDE application. In December 1996, the FDA granted the Company an IDE to
conduct in the United States a limited clinical trial of the EnSite System for left ventricular tachycardia mapping in five patients at one institution. The Company conducted in early 1997 a limited
five patient clinical study authorized under the IDE. Based on the results of those trials, the FDA approved testing of the EnSite System on an additional ten patients. The Company had completed 13 of
the 15 clinical trials in June 1997 when the FDA authorized full-scale testing of the EnSite System in 73 patients at up to five institutions in the United States. In
December 1998, the Company filed a premarket notification application with the FDA under Section 510(k) of the FDC Act containing the results of its left ventricular multi-center
clinical trials and indicating the Company's intention to commence marketing in the U.S., but the FDA did not find substantial equivalence with other devices used in the ventricles based on initial
clinical data. Following discussion with the FDA, in March 1999, the Company announced that its FDA application for left ventricular use of the EnSite System will be submitted as a PMA
application. Portions of the application have been submitted and approved, but the Company has not yet undertaken another clinical study for left ventricular use. The Company is still in discussions
with the FDA regarding the best approach to obtain market approval for left ventricular use, which may include a revised 510(k) application.

The
Company conducted an initial study of its technology for mapping atrial tachycardia in seven patients in the United Kingdom during the second half of 1996. The Company submitted an
IDE application to the FDA in June 1997 for use of the EnSite System in the right atrium, and received an IDE approval in August 1997. In September 1998, the Company filed a
510(k) application with the FDA containing the results of its right atrial multi-center clinical trials. In April 1999 received FDA approval to market the EnSite System for use in the right
atrium. In January 2001, the Company received IDE approval from the FDA for use in a multi-center clinical study of the EnSite System in the left atrium for diagnosing arrhythmias, including
atrial fibrillation. The Company began this study in the second quarter of 2001.

The Company is also required to register as a medical device manufacturer with the FDA and state agencies, and to list its products with the FDA. As such, the Company will be inspected
by both the FDA for compliance with the FDAs GMP and other applicable regulations. These regulations require that the Company manufacture its products and maintain its documents in a prescribed manner
with respect to manufacturing, testing and control activities. Further, the Company is required to comply with various FDA requirements for design, safety, advertising and labeling.

The
Company is required to provide information to the FDA on death or serious injuries alleged to have been associated with the use of its medical devices, as well as product
malfunctions that would likely cause or contribute to death or serious injury if the malfunction were to recur. In addition, the FDA prohibits an approved device from being marketed for unapproved
applications. If the FDA believes that a company is not in compliance with the law, it can institute proceedings to detain or seize products, issue a recall, enjoin future violations and assess civil
and criminal penalties against the Company, its officers and its employees. Failure to comply with the regulatory requirements could have a material adverse effect on the Company's business, financial
condition and results of operations.

The
advertising of most FDA-regulated products is subject to both FDA and Federal Trade Commission jurisdiction. The Company also is subject to regulation by the Occupational
Safety and Health Administration and by other governmental entities.

Regulations
regarding the manufacture and sale of the Company's products are subject to change. The Company cannot predict what impact, if any, such changes might have on its business,
financial condition or results of operations.



International sales of the Company's products are subject to the regulatory agency product registration requirements of each country. The regulatory review
process varies from country to country. There can be no assurance that such approvals will be obtained on a timely basis or at all.

The
Company received ISO 9001 certification for its catheter and quality system in August 1997, and ISO 9001 certification for the clinical workstation in November 1998.
The Company has obtained CE certification for the EnSite catheter and for the Ensite 3000 clinical workstation. The ISO 9000 series of standards for quality operations have been developed to ensure
that companies know the standards of quality to which they must adhere to receive certification. The European Union promulgated rules which required that medical products receive, by
mid-1998, the right to affix the CE Mark, an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. ISO 9000
certification was one of the CE Mark certification requirements.

Product Liability and Insurance

The development, manufacture and sale of medical products entail significant risk of product liability claims and product failure claims. The Company has
conducted only limited clinical trials and does not yet have, and will not have for a number of years, sufficient clinical data to allow the Company to measure the risk of such claims with respect to
its products. The Company faces an inherent business risk of financial exposure to product liability claims in the event that the use of its products results in personal injury or death. The Company
also faces the possibility that defects in the design or manufacture of the Company's products might necessitate a product recall. There can be no assurance that the Company will not experience losses
due to product liability claims or recalls in the future. The Company currently maintains product liability insurance with coverage limits of $5 million per occurrence and $5 million
annually in the aggregate and there can be no assurance that the coverage limits of the Company's insurance policies will be adequate. Product liability insurance is expensive, may be difficult to
obtain and may not be available in the future on acceptable terms, or at all. Any claims against the Company, regardless of their merit or

16

eventual outcome, could have a material adverse effect upon the Company's business, financial condition and results of operations.

Employees

The Company and its European subsidiary had a total of 190 full-time employees as of December 31, 2001. Of this number, 26 persons were engaged
in research and development, 11 were involved in regulatory and quality assurance, 81 were involved with manufacturing and 72 were involved with administration, sales and marketing and support
functions. No employee of the Company is covered by a collective bargaining agreement. In addition to its full-time workforce, the Company has consulting or other contractual relationships
with 3 other individuals. The Company expects to add such new employees as are necessary to expand its manufacturing capacity for future commercial production.

Summary

The Company was incorporated in May 1992. The Company develops, manufactures and markets the Ensite 3000 clinical workstation and EnSite catheter for use
by electrophysiologists in diagnosing and mapping abnormal heart rhythms known as tachycardias. The Ensite 3000 clinical workstation and EnSite catheter received FDA approval for right atrial use in
the U.S. during the second quarter 1999. The products are also available in full market release to electrophysiologists in Europe.

Results of Operations

Years ended December 31, 2001 and 2000

General.Net losses decreased to $8,479,043, or $0.60 per share, for the year ended December 31, 2001, from
$10,311,147, or $.92 per share, for the year ended December 31, 2000. The Company is in a period of growth in sales and marketing expenses related to market penetration, including increases in
personnel costs. The Company believes that it will still post an overall loss for the year 2002, but is expecting to show a profit for its fourth quarter of 2002.

Revenue and Cost of Goods Sold.Worldwide revenue for the year ended December 31, 2001 was $22.9 million, a
$8.3 million, or 57%, increase over the same period in 2000. In the U.S., revenues increased approximately $7.5 million, or 70%, during 2001 over 2000 revenues. Approximately
$5.9 million of the $7.5 million revenue increase in the U.S. during 2001 came from EnSite catheter sales, where unit sales increased approximately 90% over 2000. Increased utilization
per system per month during 2001 contributed to these higher unit and revenue numbers.

International
revenues increased approximately $790,000, or 21%, during 2001 over 2000 revenues. International revenues include sales direct to the end-user in Europe and Canada, and to
distributors in Europe and Asia Pacific. A majority of the increase in international revenues was related to EnSite catheter sales, where unit sales increased approximately 31% over 2000.
International revenues were also positively impacted in the fourth quarter of 2001, due to higher average selling prices on both the EnSite catheter and EnSite clinical workstation, when the Company
launched its direct selling efforts in Europe after the termination of its distribution agreement with Medtronic at the end of September 2001. The Company believes that selling directly to the
end-user will improve sales in the European market.

Other
revenue, which represents approximately 6.0% and 6.6% of worldwide sales for the years ended December 31, 2001 and 2000, respectively, includes revenue generated from
extended service contracts, repairs and accessories sales related to the EnSite clinical workstation.

EnSite
clinical workstation sales were $11.5 million for fiscal year 2001, compared to $8.4 million for the same period in 2000, or an increase of 37%. The increase is due
mainly to the higher sales of the EnSite clinical workstation in the U.S. Domestic sales accounted for 78% of total EnSite clinical workstation sales during fiscal year 2001, compared to 72% for the
same period in 2000. The Company believes EnSite clinical workstation sales will be approximately 35% to 40% of total revenues in 2002.

EnSite
catheter sales were $11 million for fiscal year 2001, compared to $5.9 million for the same period in 2000, or an increase of 87%. Domestic sales accounted for 83%
of total EnSite catheter sales during fiscal year 2001, compared to 77% for the same period in 2000. The Company believes EnSite catheter sales will be approximately 60% to 65% of total revenues in
2002.

Cost
of goods sold including unabsorbed manufacturing expenses was $9,241,039 and $7,174,431 for the years ended December 31, 2001 and 2000, respectively.

The
gross profit margin was 59.6% for the year ended December 31, 2001, compared with 50.7% during the same period in 2000. The increase in margins is mainly attributed to the
better EnSite catheter absorption of manufacturing overhead from the growth in domestic sales over the prior year. Additionally, because the Company's margins on its domestic sales are substantially
higher than those of its international

21

---

sales, the Company saw more favorable results in margins due to 81% of the revenue recorded during the year being from domestic sales, compared to 74% from the same period in 2000. Also, EnSite
catheter margin increased approximately eight percentage points above last year's margin. The Company believes gross profit margins will be, in aggregate, 5 to 6 percentage points higher in 2002 as
compared to the 59.6% attained in 2001.

Research and Development Expenses.Research and development expenses include compensation and benefit costs within the
clinical, software, hardware, catheter and applied research departments as well as costs associated with regulatory expenses. Research and development expenses were $5,271,169 for the year ended
December 31, 2001, compared to $4,459,737 during the same period in 2000, an increase of $811,432. The Company believes research and development expenditures will increase for the
2002 year, in the range of $300,000 to $600,000, mainly due to its on-going left atrium study.

General and Administrative Expenses.General and administrative expenses were $2,266,907 and $2,073,795 for the years ended
December 31, 2001 and 2000, respectively, an increase of $193,112. The increase is due primarily to higher personnel costs and professional service expenses. The Company expects general and
administrative expenses to increase slightly during the 2002 year.

Sales and Marketing.Sales and marketing expenses increased to $14,750,075 during the year ended December 31, 2001,
from $11,093,095 during the same period in 2000, an increase of $3,656,980. The increase is primarily attributable to increases in personnel and costs associated with building and training of the U.S.
and European sales and clinical team. As the Company continues to penetrate the U.S. and European markets, sales and marketing expenses are expected to increase in 2002 over 2001 as additional
headcount is added in both the selling and field clinical engineering areas.

Interest Income and Expense.Interest income was $318,208 and $604,691 for the years ended December 31, 2001 and 2000,
respectively. The decrease was due primarily to lower average cash and cash equivalent balances and lower interest rates. Interest expense was $161,367 and $677,674 for the years ended
December 31, 2001 and 2000, respectively. The decrease is directly related to the repayment of the loan to Medtronic, Inc. during February 2001.

Years ended December 31, 2000 and 1999

General.Net losses decreased to $10,311,147, or $0.92 per share, for the year ended December 31, 2000, from
$11,728,656, or $1.23 per share, for the year ended December 31, 1999. The Company is in a
period of growth in sales and marketing expenses related to market introduction, including increases in personnel costs.

Revenue and Cost of Goods Sold.Worldwide revenue for the year ended December 31, 2000 was $14.6 million, a
$5 million, or 52%, increase over the same period in 1999. Revenue for domestic sales increased $5.3 million, or 99%, compared to the same period in 1999. This increase in revenue can be
directly attributed to a higher number of EnSite clinical workstations sold during fiscal 2000, compared to the same period in 1999. Additionally, with a 158% increase in the installed base of the
EnSite clinical workstation since December 31, 1999 and an overall increase in EnSite catheter utilization per system per month, EnSite catheter revenue increased 143%. However, revenue for
international sales, which includes sales to distributors in Europe and Asia Pacific, decreased $382,000, or 9%, over the same period in 1999. A majority of this decline related to our European
distributor, Medtronic, which purchased a limited number of EnSite clinical workstations during the year and also did not increase its purchases of EnSite catheter sales over the previous fiscal year.
The Company does not believe there occurred any fundamental decline in the European market for the EnSite workstation. Rather, the Company believes that Medtronic did not devote sufficient resources
during fiscal 2000 necessary to further develop the European market. Other revenues, which represents 6.6% and 7.8% of worldwide sales for the years ending December 31,

22

---

2000 and 1999, respectively, includes revenues generated from extended service contracts, repairs and accessories sales related to the EnSite System.

EnSite
clinical workstation sales were $8.4 million for fiscal year 2000, compared to $6.2 million for the same period in 1999. The increase is due mainly to the higher
sales of the EnSite clinical workstation in the U.S., compared to last year's comparable period, or an increase of 76%. Domestic sales accounted for 72% of total EnSite clinical workstation sales
during fiscal year 2000, compared to 56% for the same period in 1999.

EnSite
catheter sales were $5.9 million for fiscal year 2000, compared to $3 million for the same period in 1999, or an increase of 97%. Domestic sales accounted for 77% of
total EnSite catheter sales during fiscal year 2000, compared to 63% for the same period in 1999.

Cost
of goods sold including unabsorbed manufacturing expenses was $7,174,431 and $6,592,409 for the years ended December 31, 2000 and 1999, respectively.

The
gross profit margin was 50.7% for the year ended December 31, 2000, compared with 31.3% during the same period in 1999. The increase in margins is mainly attributed to the
better absorption of manufacturing overhead from the growth in domestic sales over the prior year. Additionally, because the Company's margins on its domestic sales are substantially higher than those
of its international sales, the Company saw more favorable results in margins due to 74% of the revenue recorded during the year being from domestic sales, compared to 56% from the same period in
1999.

Research and Development Expenses.Research and development expenses include compensation and benefit costs within the
clinical, software, hardware, catheter and applied research departments as well as costs associated with regulatory expenses. Research and development expenses were $4,459,737 for the year ended
December 31, 2000, compared to $5,102,378 during the same period in 1999, a decrease of $642,641. The decrease is attributable to the capitalization beginning in late 1999, after reaching
technological feasibility, of software development costs related to the Clarity release.

General and Administrative Expenses.General and administrative expenses were $2,073,795 and $2,004,991 for the years ended
December 31, 2000 and 1999, respectively, an increase of $68,804. The increase is due primarily to a rise in personnel costs and professional services expense.

Sales and Marketing.Sales and marketing expenses increased to $11,093,095 during the year ended December 31, 2000,
from $7,712,522 during the same period in 1999, an increase of $3,380,573. The increase is primarily attributable to increases in personnel and costs associated with building and training of the U.S.
sales and clinical team.

Interest Income and Expense.Interest income was $604,691 and $465,060 for the years ended December 31, 2000 and 1999,
respectively. The increase was due primarily to higher average cash and cash equivalent balances. Interest expense was $677,674 and $378,609 for the years ended December 31, 2000 and 1999,
respectively. The increase is due the amount of principal outstanding on the loan to Medtronic, Inc. during 2000 versus 1999.

Liquidity and Capital Resources

On March 24, 1997, the Company received net proceeds of approximately $18,833,000 from an initial public offering of 2,250,000 shares of its common stock
and approximately $6,278,000 from a concurrent private placement to Medtronic, Inc. of 750,000 shares of its common stock. The Company's operations since inception have been funded by net
proceeds from the sales of stock totaling approximately $79.9 million through December 31, 2001. As of December 31, 2001 and December 31, 2000, the Company had cash, cash
equivalents and short-term investments of approximately $4.6 million and $10.8 million, respectively.

23

For
the year ended December 31, 2001, the Company used approximately $5.7 million of cash for operations, compared to approximately $9.6 million for the same period
in 2000. The Company saw an increase in its accounts receivable balances of approximately $1.6 million from December 31, 2000. The increase in accounts receivable is attributed to the
Company's direct selling efforts in Europe and the timing of fourth quarter 2001 sales in relation to the payment terms of these sales. Inventories decreased approximately $480,000 during 2001. In
2001, the Company implemented a more efficient
manner of managing the levels of raw material, work-in-process, and finished goods inventories, resulting in the reduced levels of inventory. The Company believes inventory
balances will increase slightly during 2002 as sales are projected to increase 47% to 49% over 2001. Accounts payable increased approximately $1.4 million since December 31, 2000.
The increase is directly attributed to the efforts of having receivable and payable turns more closely match each other in order to produce less negative cash flows. The Company expects accounts
payable to grow throughout fiscal 2002 as operating and production expenses increase to support revenue growth. Accrued salaries and related expenses increased approximately $730,000 since
December 31, 2000. A majority of this increase is attributed to a higher payout in the Company's incentive bonus program and higher quarterly bonus payouts to the sales and clinical engineers,
related to fourth quarter 2001 sales, compared to those in the comparable periods in 2000. The Company expects this accrual balance at December 31, 2002 to be slightly higher compared to that
of the December 31, 2001 balance. The Company had no short-term investment portfolio as of December 31, 2001, a decrease of $2,987,588 from the December 31, 2000
balance. The reduction is due to the Company continuing to use its available resources to fund its operating losses and to take advantage of higher interest rates in money market funds.

In
January 1999, the Company announced a financing agreement with Medtronic, Inc. Under the agreement, the Company received $7 million from Medtronic Asset
Management, which was repayable by February 2001 or, if earlier, at the close of a significant round of debt or equity financing. The Company received $3.5 million of the financing in
February 1999 and the remaining $3.5 million in January 2000. The $7 million was repaid to Medtronic Asset Management in February 2001.

In
March 2001, the Company received proceeds of $7,349,000 from a private placement of 2,449,666 shares of its common stock to accredited investors. The placement was priced at
$3.00 per share. In June 2001, the Company also announced a $3.5 million credit facility agreement with Silicon Valley Bank, consisting of a $1.5 million capital lease line and a
$2 million revolving line of credit. The credit facility expires in June 2002, but the Company expects to be able to renew the facility under similar terms. As of December 31,
2001 the Company has drawn $352,403 on the capital lease line and has $750,000 outstanding on the revolving line of credit. The agreement specifies certain restrictive covenants, which the Company was
in compliance with as of December 31, 2001.

In
February 2002, the Company received proceeds of $10,000,000 from a private placement of 1,666,667 shares of its common stock to accredited investors. The placement was priced
at $6.00 per share.

The
Company believes that its existing cash, cash equivalents, short-term investments and bank financing will be sufficient to fund the operations of the Company to
profitability, which the Company anticipates will occur in the fourth quarter of 2002. If the Company achieves profitability as expected, the need for additional financing is not presently
anticipated. The Company's future liquidity and capital requirements will depend on numerous factors, including the timing of regulatory actions regarding the Company's products, the results of
clinical trials and competition, the extent to which the Company's EnSite System gains market acceptance, the cost, timing and method of expansion of sales, marketing, research and development and
manufacturing activities and the ability of the Company to obtain additional bank financing.

Critical Accounting Policies

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S., which require the Company to make
estimates and assumptions in certain circumstances that affect amounts reported in the accompanying consolidated financial statements and related footnotes. In preparing these financial statements,
management has made its best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materially. The Company does not believe there is a great
likelihood that materially different amounts would be reported related to the accounting policies described below. However, application of these accounting policies involves the exercise of judgment
and use of assumptions as to future uncertainties and, as a result, actual results could differ from these estimates.

Revenue Recognition.Revenue from the sale of the Company's EnSite clinical workstation is recognized at the time of shipment
in instances where the Company has evidence of a contract, the fee charged is fixed and determinable, and collection is probable. Revenue from service and customer support contracts is deferred and
recognized ratably over the period the services are provided. The Securities and Exchange Commission's Staff Accounting Bulletin (SAB) No. 101, "Revenue Recognition" provides guidance on the
application of generally accepted accounting principals to selected revenue recognition issues. The Company has concluded that its revenue recognition policy is appropriate and in accordance with SAB
No. 101.

Allowance for Doubtful Accounts.Accounts receivable are reduced by an allowance for amounts that may become uncollectible in
the future. The estimated allowance is based on management's review of accounts receivable balances and historic write-offs.

Inventories and Related Allowance for Excess and Obsolete Inventory.Inventories are valued at the lower of cost or market
and have been reduced by an allowance for excess and obsolete inventories. The estimated allowance is based on management's review of inventories on hand compared to estimated future usage and sales.

New Accounting Standards.In October 2001, the FASB issued SFAS No. 144,Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, which is effective for fiscal years beginning after June 15, 2002. This statement
addresses financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes SFAS No. 121,Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions of Accounting Principles Board (APB) Opinion No. 30, Reporting the Results of
Operationsfor a disposal of a segment of a business. The adoption of this pronouncement is not expected to have a material
impact on the Company's consolidated results of operations, financial position, or cash flows.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company had approximately $4.6 million of cash and investments on December 31, 2001. Substantially all of the investments were U.S. government
or investment grade, fixed income securities from domestic issuers. Because of the credit risk criteria of the Company's investment policies, the primary market risk associated with these investments
is interest rate risk. The Company does not use derivative financial instruments to manage interest rate risk or to speculate on future changes in interest rates. A rise in interest rates could
negatively affect the fair value of the Company's investments; however, because management considers it unlikely that the Company would need or choose to substantially liquidate the Company's
investments prior to their maturity, management believes that such an increase in interest rates would not have a material impact on the Company's future earnings or cash flows. Even though the
Company conducts sales in foreign currencies through its European subsidiary, management does not believe the Company is exposed to any material foreign currency exchange rate risk.

We
have audited the accompanying consolidated balance sheets of Endocardial Solutions, Inc. as of December 31, 2001 and 2000, and the related consolidated statements of
operations, changes in stockholders' equity and cash flows for each of the three years in the period ended December 31, 2001. 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 in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable
assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In
our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Endocardial Solutions, Inc. at
December 31, 2001 and 2000, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting

Endocardial Solutions, Inc.        Notes to Consolidated Financial Statements        December 31, 2001

1.    Description of Business

Endocardial Solutions, Inc. (the Company) designs, develops and manufactures a minimally invasive and integrated system that locates and facilitates
treatment of cardiac arrhythmias. Arrhythmias are abnormal heart rhythms caused by disorders interfering with the normal electrical activity of the heart, which, if undetected and untreated, can cause
palpitations, dizziness and fainting, or sudden cardiac death. The Company is developing products to diagnose ventricular tachycardia, a widespread, complex and serious form of arrhythmia, and intends
to utilize its technology to produce products to diagnose atrial arrhythmias, including atrial fibrillation. The Company believes that its proprietary technology will enable physicians to rapidly and
accurately map the heart's electrical activity and locate the abnormal heart rhythms through three-dimensional imaging.

2.    Summary of Significant Accounting Policies

Basis of Consolidation

The consolidated financial statements include the accounts of Endocardial Solutions, Inc. and its wholly owned subsidiary after elimination of intercompany
accounts and transactions.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. At December 31, 2001 and
2000, the Company's cash equivalents consisted of investments in government securities carried at amortized cost which approximated market value, with no resulting unrealized gains and losses
recognized.

Revenue Recognition

Revenue from the sale of the Company's system is recognized at the time of shipment in instances where the Company has evidence of a contract, the fee charged is
fixed and determinable, and collection is probable.

Deferred
revenue originates from maintenance agreements the Company enters into with its customers. With the initial sale of an EnSite clinical workstation the Company offers a standard
one-year maintenance agreement on the system, which covers repairs and service of the patient interface unit and the Silicon Graphics display workstation. It also covers any software
upgrades released during this time frame. Subsequent to the expiration of the first year standardized maintenance agreement, customers are able to purchase an extended one-year maintenance
agreement to cover repair and service costs and also any software upgrade released in this time frame. Long-term deferred revenue originates from sales of extended maintenance agreements.
Revenue from maintenance agreements is recognized ratably over the period the services are provided.

Software Development Costs

The Company capitalizes software development costs in accordance with Statement of Financial Accounting Standards No. 86, Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed. The capitalization of these costs begins when a product's
technological feasibility has been established and ends when the product is available for general release to customers. The Company amortizes these costs over an estimated economic useful life of
18 months.

31

---

Furniture and Equipment

Furniture and equipment are recorded at cost. Depreciation is provided using the straight-line method over the estimated useful lives of the assets
ranging from three to seven years. Amortization of assets recorded under capital leases is provided using the straightline method over the life of the lease.

Patents

Patent costs are being amortized on a straight-line basis over five years. The Company periodically reviews its patents for impairment in value. Any
adjustment from the analysis is charged to operations.

Short-Term Investments

Short-term investments consist of U.S. Government obligations and corporate debt securities with maturities of less than one year. At
December 31, 2000, the Company had $523,170 in U.S. Government obligations and $2,464,418 in corporate debt securities. Management determines the appropriate classification of debt and equity
securities at the time of purchase and reevaluates such designation as of each balance sheet date. Management has classified the debt securities as available for sale. Available for sale securities
are carried at fair value with the unrealized gains and losses, net of tax, reported as a separate component of shareholders' equity. At December 31, 2000, the fair value of the Company's
investments approximates cost.

Income Taxes

Income taxes are accounted for under the liability method. Deferred income taxes are provided for temporary differences between financial reporting and tax bases
of assets and liabilities.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Inventories

Inventories are valued at the lower of cost (first-in, first-out method) or market.

Stock-Based Compensation

The Company has adopted the disclosure-only provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation, but applies Accounting Principles Board Opinion No. 25 (APB 25) and related interpretations in
accounting for its options granted to employees and directors. Under APB 25, when the exercise price of employee stock options equals the market price of the underlying stock on the date of grant, no
compensation is recognized.

32

---

Impairment of Long-Lived Assets

The Company will record impairment losses on long-lived assets used in operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets' carrying amount.

Net Loss Per Share

Basic loss per share is computed using the weighted average number of common shares outstanding. Diluted loss per share is computed using the combination of
dilutive common share equivalents and the weighted average number of common shares outstanding. Diluted earnings per share is not separately presented, as the effect of outstanding options and
warrants is antidilutive.

Foreign Currency Translation and Transactions

Foreign assets and liabilities are translated using the year-end exchange rate. Results of operations are translated using the average exchange rates
throughout the year. Translation gains or losses, net of applicable deferred taxes are accumulated as a separate component of stockholders' equity.

New Accounting Standards

In October 2001, the FASB issued SFAS No. 144,Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of, which is effective for fiscal years beginning after June 15, 2002. This statement addresses financial accounting and
reporting for the impairment or disposal of long-lived assets and supersedes SFAS No. 121,Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to be Disposed Of, and the accounting and reporting provisions of Accounting Principles Board (APB) Opinion No. 30, Reporting the Results of Operationsfor a disposal of a segment of a business. The adoption of this pronouncement is not expected to have a material
impact on the Company's consolidated results of operations, financial position, or cash flows.

outstanding under the stock option plans expire at various dates during the period from April 2003 through October 2011. Exercise prices for options outstanding as
of December 31, 2001 ranged from $.20 to $13.13 per share. The number of options exercisable as of December 31, 2001, 2000 and 1999 were 1,262,661, 988,584, and 766,414, respectively, at
weighted-average exercise prices of $5.59, $5.32, and $3.97 per share, respectively.

The
weighted-average grant date fair value of options granted during the years ended December 31, 2001, 2000 and 1999 was $2.21, $4.83, and $4.63 per share, respectively.

Pro
forma information regarding net loss and loss per share is required by Statement 123, and has been determined as if the Company had accounted for its employee stock options under the
fair value method of Statement 123. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions for
2001, 2000 and 1999: risk-free interest rates ranging from 4.42% to 6.18%, dividend yields of -0-, volatility factors of the expected market price of the Company's
stock ranging from .61 to .87 and a weighted-average expected life of the options of four years.

The
Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition,
option valuation models require the input of highly subjective assumptions. Because the Company's employee stock options have characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of
the fair value of its employee stock options.

For
purposes 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 is as
follows:

The
Company also has an Employee Stock Purchase Plan under which 200,000 shares have been reserved for purchase by employees. The purchase price of the shares under the Plan is the
lesser of 85% of the fair market value on the first or last day of the offering period. Offering periods are each three months. Employees may designate up to 15% of their compensation for the purchase
of stock under the Plan. There have been no shares issued under the Plan.

7.    Deferred Compensation

During the years ended December 31, 2001, 2000, and 1999, the Company granted stock options for the purchase of 125,000 shares, 31,247 shares, and 95,000
shares, respectively, of common stock to individuals where the exercise price was less than the fair market value of the stock on the date of grant. As a result,
the Company recorded deferred compensation for the excess of deemed value for accounting purposes of the common stock issuable upon exercise of such options over the aggregate exercise price of such
options of $315,000, $7,812, and $35,628, respectively, in 2001, 2000, and 1999. For the years ended December 31, 2001, 2000, and 1999, the Company recognized expense of $61,412, $16,719, and
$98,730, respectively, associated with such stock option grants.

8.    Income Taxes

At December 31, 2001, the Company had net operating loss carryforwards of approximately $67,090,000. The net operating loss carryforwards are available to
offset future taxable income and begin to expire in the year 2009. No benefit has been recorded for such loss carryforwards, and utilization in future years may be limited under Section 382 of
the Internal Revenue Code if significant ownership changes have occurred.

9.    Sources of Supply

The Company purchases raw materials and certain key components of its products, including the computer workstation and certain components for its catheter from
sole, single or limited source suppliers. The Company currently has no agreements that would ensure delivery of raw materials and components from such suppliers. Establishing additional or replacement
suppliers for any of the numerous components used in the Company's products, if required, may not be accomplished quickly and could involve significant additional costs. The inability of any of the
Company's suppliers to provide an adequate supply of components in a timely manner, or the inability of the Company to locate qualified alternative suppliers for material and components at reasonable
costs, could adversely affect the Company's business, financial condition and results of operations.

10.    License Agreement

In January 1998, the Company entered into a license agreement with Medtronic, Inc. to license certain technology developed by Medtronic. As
consideration for the rights to utilize the developed technology, the Company paid Medtronic $1,500,000 and granted Medtronic a warrant to purchase 447,554 shares of the Company's common stock at an
exercise price of $11.1125. The warrant expires in January 2002. The warrant was deemed to have a value of $2,085,602. This amount, along with the cash payment to Medtronic, has been expensed
as research and development. If the Company develops a product that reaches commercialization, the Company will grant to Medtronic an additional warrant to purchase 223,777 shares of common stock. The
exercise price of the warrant will be 1.25 times the average closing price of the Company's common stock for the twenty days prior to the commercial products introduction. The value of the additional
warrants will be amortized over the shorter of the license agreement or the life of the developed product.

This
additional warrant becomes exercisable one year after being granted and remains outstanding for five years. The additional warrant will also be granted if the Company undergoes a
change in control. If the warrant is granted due to a change in control, it becomes immediately exercisable.

11.    Note Receivable Officer

In January 2001, the Company entered into a $371,250 full recourse note agreement with an officer of the Company for the purchase of 110,000 shares of the
Company's common stock. The note bears interest at 9.5% per year and is due in full in January 2006.

12.    Significant Customer

The Company had a distributor that represented 6%, 16%, and 42% of all net revenues for the years ended December 31, 2001, 2000 and 1999, respectively.
