FACE="Times New Roman" SIZE="2">We develop, manufacture and sell innovative surgical devices designed to create precise lesions, or scars, in cardiac and soft tissues. Medical journals have described the adoption by leading cardiothoracic surgeons
of the AtriCure bipolar ablation system as a standard treatment alternative during open-heart surgical procedures to safely, rapidly and reliably create lesions in cardiac, or heart, tissue to block the abnormal electrical impulses that cause atrial
fibrillation, or AF, a rapid, irregular quivering of the upper chambers of the heart. AF is associated with an increased risk of stroke and is often accompanied by such symptoms as fatigue, shortness of breath and heart palpitations. Sales of our
products reached approximately $9.8 million for 2003, the first full year of general sales of our products, approximately $19.2 million for 2004, and approximately $31.0 million for 2005. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Cardiothoracic surgeons have adopted our system to treat AF in over 25,000 patients since its general commercial release in the United States in January
2003. We believe that the AtriCure bipolar ablation system is currently a market leader in the surgical treatment of AF during open-heart surgical procedures, such as bypass or valve surgery, and surgeons have used our system as a sole-therapy
minimally invasive treatment for AF, which is performed on patients who are not undergoing a separate open-heart procedure, on over 800 patients. Our system is currently being used in 23 of the 25 highest volume heart centers in the United States.
We do not believe that our system is currently being used for its Food and Drug Administration, or FDA, cleared indications, and, accordingly, substantially all of our revenue is currently generated through the non-FDA-approved, or off-label, use of
our system for the treatment of AF. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The AtriCure bipolar ablation system, our primary product, consists of a compact power generator known
as an ablation sensing unit, or ASU, and several uniquely designed disposable ablation clamps that connect to the ASU, including two newly developed Isolator endoscopic ablation clamps that are specifically designed for use in sole-therapy minimally
invasive procedures. We also market the Isolator bipolar pen and the Wolf dissector, which are separate from, but complement, our system and we distribute cryoablation systems that use extreme cold to ablate tissue. </FONT></P> <P

<FONT FACE="Times New Roman" SIZE="2">risk of developing AF, and the incidence of AF increases with age. More than five million people worldwide, including approximately 2.4&nbsp;million
Americans, are currently afflicted with AF. According to the American Heart Association, approximately 15% to 20% of the estimated 700,000 strokes that occur annually in the United States are attributable to AF and people with AF are approximately
five times more likely to have a stroke. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">AF is a condition that doctors often find difficult to treat, and historically there has been no
widely accepted cure for AF. Doctors typically begin treating AF with drugs, which are often ineffective, not well-tolerated and may be associated with serious side effects. Patients who cannot effectively be treated with drugs occasionally undergo
catheter-based procedures to treat their AF, but catheter-based procedures have not been widely adopted because they are technically challenging, can be associated with serious complications and yield inconsistent results. Implantable devices, such
as pacemakers and defibrillators, are sometimes used to reduce the frequency and symptoms of AF, although they do not treat the underlying disease. In the past, an open-heart surgical procedure known as the classic Maze was used to treat AF, but
this procedure has not been widely adopted because it is technically challenging, highly invasive and involves long recovery times. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The
creation of transmural, or full-thickness, lesions is thought to be a critical factor in the successful treatment of AF when performing ablation treatments. Prominent medical journals, which contain articles that were written, in part, by leading
cardiothoracic surgeons who are consultants to us, describe how cardiothoracic surgeons have used our system to safely, rapidly and reliably create transmural lesions when treating AF either during an elective open-heart surgical procedure, such as
bypass or valve surgery, or as a sole-therapy minimally invasive procedure. As indicated in these studies, cardiothoracic surgeons using our system have created individual transmural lesions in the heart in a matter of seconds and have treated AF in
approximately 20 minutes during open-heart surgical procedures and in approximately two to three hours as a sole-therapy minimally invasive procedure. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2">The FDA has cleared the AtriCure bipolar ablation system for the ablation, or destruction, of soft tissues in general and non-cardiac related surgical procedures but to date has not cleared or approved our system for
cardiac use or for the treatment of AF. In June 2005, the FDA denied 510(k) clearance for use of our system to ablate cardiac tissue because the FDA determined that our system is not substantially equivalent to an already FDA-cleared device. The FDA
has taken a position that no radio-frequency surgical clamps are general cardiac tools because radio-frequency surgical clamps are specifically designed and intended for use in surgical ablation to treat AF. As such, no radio-frequency surgical
clamps from any medical device company, including ours, have been cleared for cardiac ablation to date. This means that we would now be required to gain FDA approval to market the device through the submission of a pre-market approval application,
or PMA, a lengthier process, in order to gain FDA approval of our system for the cardiac indication. While we may appeal the FDA&#146;s decision, receipt of that 510(k) clearance would not eliminate the need to seek FDA approval through a separate
PMA for the use of our system to treat AF. After conducting necessary clinical trials, we intend to seek FDA approval as early as 2009 for the use of our system to treat AF, which we view as our market opportunity. We did receive FDA clearance in
June 2005 for the use of our Isolator bipolar pen for the surgical ablation of cardiac tissue, and we believe that cardiothoracic surgeons will use our pen device for that use. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Although the use of our system to treat AF remains investigational and we are still seeking FDA approval in connection with use of our system for the
treatment of AF, preliminary clinical studies conducted by doctors at leading cardiac care centers provide support for our system&#146;s ability to safely, rapidly and reliably create the lesions needed to block the abnormal electrical impulses that
cause AF. We believe that those studies indicate that we have a significant competitive advantage in the treatment of AF. Several preliminary clinical studies, including a 27-patient study, a 40-patient study, a 47-patient study and a 276-patient
study, in which several of our consultants participated and that were published in <I>The Journal of Thoracic and Cardiovascular Surgery</I>, found that approximately 90% of study participants treated using our system were free of AF at six-month
follow-up. This success rate was achieved both when our system was used as a sole-therapy minimally invasive approach and when it was used during open-heart surgical procedures. We believe the overall demand for our system will increase, including
demand for our system as a sole-therapy minimally invasive AF treatment, which we believe will ultimately represent our largest growth opportunity. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">AF is a condition where abnormal electrical impulses cause the atria, or upper chambers of the heart, to fibrillate, or quiver, at rapid rates of 400 to
600 times per minute. As a result of this quivering, blood in the atria becomes static, creating an increased risk that a blood clot will form and cause a stroke or other serious complications. If AF persists, patients generally progress from
experiencing AF intermittently to having AF continuously, a condition that is more difficult to treat. Symptoms of AF may include heart palpitations, dizziness, fatigue and shortness of breath, and these symptoms may be debilitating and life
threatening in some cases. Although there is often no apparent cause of a patient&#146;s AF, the condition is often associated with high blood pressure and other forms of heart disease. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">AF is the most commonly diagnosed sustained cardiac arrhythmia, and affects more than five million people worldwide, including more than 2.4&nbsp;million
Americans, where approximately 160,000 new cases of AF are diagnosed each year. According to an article in the April 2001 edition of <I>The New England Journal of Medicine</I>, it is estimated that the incidence of AF doubles with each decade of an
adult&#146;s life. AF affects approximately 6% of all people 65 years and older in the United States. Studies show that one in four people over the age of 40 in the United States has a lifetime risk of developing AF, and the incidence of AF
increases with age. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">According to the American Heart Association, people with AF are about five times more likely to have a stroke, and AF
is thought to be responsible for approximately 15% to 20% of the estimated 700,000 strokes that occur annually in the United States. According to the National Center for Health Statistics, AF also accounts for an estimated 3.2&nbsp;million office
visits and more than 465,000 hospitalizations annually in the United States. According to <I>Medtech Insight</I>, AF accounts for more than $6 billion in healthcare costs each year in the United States. According to the<I> Journal of the American
Medical Association</I>, the number of patients with AF in the United States will continue to increase. AF is an underdiagnosed condition due in large part to the fact that patients with AF often have mild or no symptoms, and their AF is only
diagnosed when they seek treatment for an associated condition, such as a stroke or heart disease. We believe that increasing awareness of AF and improved diagnostic screening will result in an increase in the number of patients diagnosed with AF.
Also, since the prevalence of AF increases with age, there will likely be an increase in the number of diagnosed AF patients in the United States as the population ages. Of the patients undergoing open-heart surgery in the United States, we estimate
that approximately 75,000 of these patients are candidates for surgical ablation using our system. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Of the United States population
diagnosed with AF, approximately 12% of these patients are symptomatic and do not respond to drug therapy or are intolerant to the drugs used to treat AF. For these patients, the classic Maze procedure is typically too invasive and catheter-based
treatments have not been widely adopted. Accordingly, we believe that there is a large population of undertreated patients who would potentially benefit from sole-therapy minimally invasive AF treatment using our system, and that these patients will
ultimately comprise our largest growth opportunity. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Because the FDA has not cleared or approved our system for the ablation of cardiac
tissue or the treatment of AF, we and others acting on our behalf may not promote our system for these uses, make any claim that our system is safe and effective for these uses or train doctors to use our system for these uses outside of the
clinical trial setting. However, these restrictions do not prevent doctors from choosing to use our system for the treatment of AF or prevent us from engaging in sales and marketing efforts that focus only on the general attributes of our system and
its FDA-cleared uses and not on the ablation of cardiac tissue or the treatment of AF. Although we educate and train doctors as to the general skills involved in the proper use of our system and its technology, we do not educate or train them to use

the lesion is transmural, or full-thickness. Our system&#146;s unique jaws firmly clamp and compress the targeted tissue being ablated, allowing surgeons to create in a matter of seconds transmural lesions that are required to block the abnormal

bipolar radio-frequency energy. Based on our proprietary software, the energy delivered to the tissue varies depending on the thickness and type of tissue being ablated. Currently, we sell six different Isolator ablation clamps of various
configurations and we generally lend our ASU to doctors and hospitals that purchase our disposable ablation clamps. All of our Isolator ablation clamps have jaws that are capable of compressing individual or multiple layers of tissue to direct and
confine the treatment to the tissue targeted for ablation. We recently introduced two new Isolator endoscopic ablation clamps that are specifically designed for use in sole-therapy minimally invasive procedures. These ablation clamps can be used
with our unique glide-path transfer guide and are designed to simplify our sole-therapy minimally invasive procedure, making it more adaptable to a broader number of surgeons and allowing surgeons the ability to perform a completely thorascopic

surgeons use the AtriCure bipolar ablation system to treat patients with AF. Surgeons report that ablation using our system generally adds approximately 20 minutes to an open-heart surgical procedure. Surgeons use our system to create sets of
lesions that may vary depending on the length of time a patient has been diagnosed with AF and whether the patient&#146;s AF is intermittent or continuous. Patients who have been diagnosed with AF for a longer duration and have more continuous AF
generally receive more ablation treatment than patients who have been diagnosed with AF for a shorter duration or who have intermittent AF. Ablation using our system during an open-heart procedure typically involves the following steps: </FONT></P>
<P STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><I>Pulmonary Vein Isolation</I>. Regardless of the duration or type of AF, surgeons will create lesions in the tissue surrounding the pulmonary veins
to create an electrical barrier between the pulmonary veins and the atrium, or upper chamber of the heart. In patients with intermittent AF, those lesions are often the extent of the treatment required to treat their AF. Cardiothoracic surgeons
report that using our system enables them to safely, rapidly and reliably create lesions to achieve electrical isolation of the pulmonary veins from the atrium. In order to perform this procedure, surgeons position the jaws of our Isolator ablation
clamps on the cardiac tissue surrounding the pulmonary veins. The jaws are clamped and the system is activated. Seconds later, an audible tone alerts the surgeons that the tissue no longer conducts energy, indicating that the lesion has become
transmural and that the pulmonary veins have been electrically isolated. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><I>Additional Lesions</I>. For those patients who have been
diagnosed with AF for a longer period and have more continuous AF, doctors may determine that additional lesions may be required to treat their AF. In cases where patients require such additional lesions, surgeons may use our system and our Isolator
bipolar pen to create lesions in the atrium that are intended to reproduce similar electrical barriers to those created by surgeons during the classic Maze procedure. As with pulmonary vein isolation, doctors report that each lesion generally takes
only seconds to create using our system. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

 <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">We and many of our competitors have developed surgical ablation devices that have been used to treat AF
during open-heart surgical procedures. We and these competitors utilize a variety of different technologies as energy sources for the ablation devices, including laser technology, microwave, cryothermy, high-intensity focused ultrasound, and radio
frequency technologies. Each of these companies is also currently working with its core technology to develop devices that can be used as a sole-therapy minimally invasive AF treatment. </FONT></P> <P

These companies sell products that are used by doctors to treat the population of patients that have AF but are not candidates for open-heart surgery, which is the same group of patients that we believe would most benefit from sole-therapy minimally
invasive AF treatments using the AtriCure bipolar ablation system. Some of these catheter-based treatments already have FDA clearance or approval for cardiac use, including the treatment of certain arrhythmias, although none has approval for the
treatment of AF. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">We believe that we compete favorably against companies that have products that are currently being used for the surgical
treatment of AF, particularly in the market for devices that are being used for the treatment of AF as a sole-therapy minimally invasive procedure, although we cannot assume that we will be able to continue to do so in the future or that new devices
that perform better than our system will not be introduced. We also believe that our system competes favorably when compared to catheter-based treatments. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2">Because of the size of the AF market and the unmet need for an AF cure, competitors have and will continue to dedicate significant resources to aggressively market their products. New product developments that could

Reimbursement </B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Payment for patient care in the United States is generally made by third-party payors. These payors include private
insurers and government insurance programs, such as Medicare or Medicaid. The Medicare program, the largest single payor in the United States, is a federal health benefit program administered by the Centers for Medicare and Medicaid Services, or
CMS, and covers certain medical care items and services for eligible elderly, blind, and disabled individuals. The coverage under Part A of the Medicare program includes hospital and other institutional services, while Part B of Medicare includes
doctors&#146; services. Because Medicare beneficiaries comprise a large percentage of the populations for which our system is used, and private insurers may follow the coverage and payment policies for Medicare, Medicare&#146;s coverage and payment
policies are significant to our operation. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The original fee-for-service portion of the Medicare Part A program pays hospitals for
inpatient services under a prospective payment system, which provides for a pre-determined payment amount based on a patient&#146;s discharge diagnosis. Discharge diagnoses are grouped into Diagnosis Related Groups, or DRGs, which determine the
payment amount for the inpatient hospital services. The payment amount is intended to reflect the costs of admitting and treating the patient. These payment amounts differ for each inpatient discharge. Currently, hospitals do not receive any

<FONT FACE="Times New Roman" SIZE="2">inpatient treatment of AF as part of an open-heart procedure. In these cases, the use of an ablation device to provide the AF treatment is included in the
payment for the open-heart procedure. Sole-therapy minimally invasive AF treatment also qualifies for payment from the fee-for-service Medicare Part A program, which allows the hospital to receive payment for this type of AF treatment. The Medicare
program has adopted specific hospital inpatient treatment codes describing AF treatment by ablation in sole-therapy and open-heart procedures such as those provided through the use of the AtriCure bipolar ablation system. However, the existing
Medicare inpatient coverage, coding or payment polices are subject to change by CMS. As a result, the continuance of current coverage, coding or payment determinations cannot be guaranteed, and any change may have an adverse impact on our
operations. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Doctors are reimbursed for their services separately under the Medicare Part B physician fee schedule. Doctors performing AF
treatment during an open-heart procedure receive a payment that reflects several factors, including the time and complexity of the AF treatment. Doctors who perform a sole-therapy minimally invasive procedure receive payment that is comparable to
the reimbursement paid to doctors for performing an open-heart surgical procedure. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Claims for procedures using our system are typically
submitted by the doctor to Medicare Part B carriers (typically insurance companies under contract to CMS) or other health insurers using established billing codes, including the Current Procedural Terminology, or CPT, billing codes maintained by the
American Medical Association. The billing codes identify the procedure or procedures performed and are relied upon to determine third-party payor amounts. Existing CPT billing codes describe surgical cardiac ablation procedures. Market acceptance of
our products is dependent on coverage and adequate payment levels from such payors. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Currently, we believe that the AF treatment
reimbursement rates are adequate for doctors and hospitals to cover the use of our system for the treatment of AF. In 2005, we estimate that the national Medicare payment rate for an open-heart procedure, whether or not the AF treatment is included,
was approximately $24,000 to $45,000, depending on the type of open-heart procedure being performed, the geographic region and the type of facility. We estimate that the national medical hospital rates for AF treatment performed as a sole-therapy
minimally invasive treatment were approximately $24,000 to $49,000, depending on the geographic region and type of facility. The cost of AF treatment performed during open-heart surgical procedures is not reimbursed separately by the Medicare
program and the reimbursement rules for open-heart surgical procedures include supplies, including the use of an ablation device, but exclude doctor&#146;s fees for these procedures, which payors remit to doctors in addition to the amounts paid to
hospitals for AF treatment procedures. Payment rates of other third-party payors may be the same as or higher or lower than Medicare rates, depending on their particular reimbursement methodology. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In addition to the Medicare program, many private payors look to CMS policies as a guideline in setting their coverage policies and payment amounts. The
current coverage policies of these private payors may differ from the Medicare program, and the payment rates they make may be higher, lower, or the same as the Medicare program. If CMS or other agencies decrease or limit reimbursement payments for
doctors and hospitals, this may affect coverage and reimbursement determinations by many private payors. Additionally, some private payors do not follow the Medicare guidelines, and those payors may reimburse only a portion of the cost of AF
treatment, or not at all. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The AtriCure bipolar ablation system has received FDA clearance for the ablation and coagulation of soft tissues
during certain non-cardiac-related surgical procedures. However, because the FDA does not regulate the practice of medicine, doctors may use the AtriCure bipolar ablation system in other circumstances where they deem it medically appropriate, even
though the FDA has not approved or cleared our system for that indication. In these circumstances, some government or private payors, including some Medicare carriers, may make coverage and payment determinations on a case-by-case basis.
Additionally, some government or private payors may deem the treatment of AF using the AtriCure bipolar ablation system for indications not approved or cleared by the FDA to be experimental or not medically necessary and, as such, may not provide
coverage or payment. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

manufacturer of our disposable Isolator ablation clamps, which are an essential component of the AtriCure bipolar ablation system, for an aggregate purchase price of approximately $7 million. In addition, under the terms of the merger agreement that
we entered into with Enable, if certain Enable assets unrelated to the AtriCure bipolar ablation system are sold prior to the third anniversary of the closing of our acquisition of Enable, we will be required to pay the former shareholders of Enable
50% of the consideration from that sale that is in excess of $1 million, subject to a maximum payment to the Enable shareholders of $2 million. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"
SIZE="2">Prior to our acquisition, Enable was comprised of two business units, Enable Surgical Products and Enable Design and Manufacturing. The Surgical Products unit was engaged in the research and development of radio-frequency energy-based
surgical products. The Surgical Products unit distributed a line of bipolar scissors in the United States, Europe, and Asia and had a portfolio of radio-frequency technologies covered by U.S. and European patents that were being considered for

by the FDA, as well as other federal and state regulatory bodies in the United States and comparable authorities in other countries. We currently market our system in the United States under a 510(k) clearance for the ablation and coagulation of
soft tissues during general, ear, nose and throat, thoracic, gynecologic and urologic surgical procedures. Currently, our system may not be marketed for ablation of cardiac tissue or for the treatment of AF without obtaining additional clearances
and approvals from the FDA. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The FDA requires that premarket approval, or PMA, be obtained for a device before it can be marketed for the
treatment of AF. A PMA will require clinical data supporting the safe and effective use of the device in the treatment of AF. In December 2003, we received an investigational device exemption, or IDE, from the FDA to conduct clinical trials of our
system in a prospective, multi-center trial, known as the RESTORE-SR trial, to evaluate the safety and efficacy of our system for the treatment of AF during open-heart surgery. In addition, in July 2005, we received FDA approval to conduct a
clinical study to demonstrate the feasibility of using the AtriCure bipolar system for the sole-therapy minimally invasive treatment of AF that also includes removal of a portion of the heart called the left atrial appendage. If this feasibility
study is successful, we would need to conduct a pivotal trial to support marketing authorization. We cannot assure you that we will successfully complete RESTORE-SR or RESTORE-SR II, receive approval for any additional clinical trials or submit and
obtain approval for our system for use in treating AF. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The Wolf dissector, the Isolator bipolar pen, and the AtriCure Cosgrove-Gillinov

devices are classified into one of three classes&#151;Class I, Class II, or Class III&#151;depending on the degree of risk associated with each medical device. Devices deemed to pose lower risks are placed in either Class&nbsp;I or II, which
requires the manufacturer to submit to the FDA a 510(k) notification requesting clearance to commercially distribute the device. Some low risk devices are exempted from this requirement. Devices deemed by the FDA to pose the greatest risk, such as
life-sustaining, life-supporting or implantable devices, or devices deemed not substantially equivalent to a previously cleared 510(k) device, or predicate device, are placed in Class III, requiring submission of a PMA supported by clinical trial
data. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The FDA has previously classified the AtriCure bipolar ablation system as a Class II device and has granted us 510(k) clearance to
market this product for the ablation and coagulation of soft tissues during certain surgical procedures. The FDA denied 510(k) clearance of our system for the ablation of cardiac tissue because the FDA determined that our system is not substantially
equivalent to an already cleared device. The FDA has taken a position that no radio-frequency surgical clamps are general cardiac tools because radio-frequency surgical clamps are specifically designed and intended for use in surgical ablation to
treat AF. As such, no radio-frequency surgical clamps from any medical device company, including ours, have been cleared for cardiac ablation to date. The FDA has reclassified our system as a Class III device, which means that we would now be
required to obtain a PMA prior to any promotion of our system for the ablation of cardiac tissue. We may appeal the FDA&#146;s decision, but if that appeal is not successful, we would not intend to pursue a PMA for the ablation of cardiac tissue
using our system and would instead pursue only the PMA for use of our system to treat AF. In order to market our system for the treatment of AF, the FDA requires that we seek approval through submission to the FDA of a PMA. Submission of a PMA is a
much more demanding process than the 510(k) notification process. Both 510(k)s and PMAs must now be submitted with a potentially substantial user fee payment to the FDA, although certain exemptions and waivers can apply, including certain exemptions

clearance often takes significantly longer than 90 days, and may take up to one year or more. If the FDA determines that the device, or its intended use, is not substantially equivalent to a previously-cleared device or use, the device is
automatically placed into Class III, requiring the submission of a PMA. Any modification to a 510(k)-cleared device that would constitute a major change in its intended use, design or manufacture, requires a new 510(k) clearance or, possibly, in
connection with safety and effectiveness, approval of a PMA. The FDA requires every manufacturer to make the determination regarding a new 510(k) submission in the first instance, but the FDA may review any manufacturer&#146;s decision. We have made
modifications to elements of our system, but we do not believe that such modifications will require us to seek additional 510(k) clearance. The FDA may not agree with our decisions regarding whether new 510(k) clearances are required. If the FDA
disagrees with us and requires us to submit a new 510(k) or PMA, we may be required to cease marketing or to recall the modified product until we obtain clearance or approval. In addition, we could be subject to significant regulatory fines or
penalties. Furthermore, our products could be subject to recall if the FDA determines, for any reason, that our products are not safe or effective. Delays in receipt or failure to receive clearances or approvals, the loss of previously received
clearances or approvals, or the failure to comply with existing or future regulatory requirements could reduce our sales, profitability and future growth prospects. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2"><B><I>Premarket Approval Pathway.</I></B> A PMA must be submitted to the FDA if the device cannot be cleared through the 510(k) process. The PMA process is much more demanding than the 510(k) notification process. A
PMA must be supported by extensive data, including but not limited to technical, preclinical, clinical trials, manufacturing and labeling to demonstrate to the FDA&#146;s satisfaction the safety and effectiveness of the device. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">After a PMA is submitted and the FDA has determined that the application is sufficiently complete to permit a substantive review, the FDA will accept the
application for filing. The FDA has 180 days to review an &#147;accepted&#148; PMA, although the review of an application generally occurs over a significantly longer period of time and can take up to several years. During this review period, the
FDA may request additional information or clarification of the information already provided. Also, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to
the approvability of the device. In addition, the FDA will conduct a preapproval inspection of the manufacturing facility to ensure compliance with quality system regulations. New PMAs or PMA supplements are required for significant modification to
the device, including indicated use, manufacturing process, labeling and design of a device that is approved through the premarket approval process. PMA supplements often require submission of the same type of information as a PMA, except that the
supplement is limited to information needed to support any changes from the device covered by the original PMA and may not require as extensive clinical data or the convening of an advisory panel. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B><I>Clinical Trials.</I></B> Clinical trials are generally required to support a PMA and are sometimes required for 510(k) clearance. In the United
States, clinical trials for a significant risk device require the prior submission of an application for an IDE to the FDA for approval. An IDE amendment must also be submitted before initiating a new clinical study under an existing IDE, such as
initiating a pivotal trial following the conclusion of a feasibility trial. The IDE application must be supported by appropriate data, such as animal and laboratory testing results, and any available data on human clinical experience, showing that
it is safe to test the device in humans and that the testing protocol is scientifically sound. The animal and laboratory testing must meet the FDA&#146;s good laboratory practice requirements. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The IDE and any IDE supplement for a new trial must be approved in advance by the FDA for a specific number of patients. Clinical trials for significant
risk devices may not begin until the IDE application or IDE supplement is approved by the FDA and the appropriate institutional review boards, or IRBs, overseeing the welfare of the research subjects and responsible for that particular clinical
trial. If the product is considered a non-significant risk device under FDA regulations, only the patients&#146; informed consent and IRB approval are </FONT>

amendment, grant an approval with certain conditions, or identify deficiencies and request additional information. It is common for the FDA to require additional information before approving an IDE or amendment for a new trial, and thus final FDA
approval on a submission may extend beyond the initial 30 days. The FDA may also require that a small-scale feasibility study be conducted before a pivotal trial may commence. In a feasibility trial, the FDA limits the number of patients, sites and
investigators that may participate. Feasibility trials are typically structured to obtain information on safety and to help determine how large a pivotal trial should be to obtain statistically significant results. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Clinical trials are subject to extensive recordkeeping and reporting requirements. Our clinical trials must be conducted under the oversight of an IRB

complies with both FDA requirements and state and federal privacy and human subject protection regulations. We, the FDA or the IRB may suspend a clinical trial at any time for various reasons, including a belief that the risks to study subjects
outweigh the anticipated benefits. Even if a trial is completed, the results of clinical testing may not adequately demonstrate the safety and efficacy of the device or may otherwise not be sufficient to obtain FDA approval to market the product in
the United States. Similarly, in Europe the clinical study must be approved by a local ethics committee and in some cases, including studies with high-risk devices, by the ministry of health in the applicable country. </FONT></P> <P

criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from Medicare, Medicaid and other federal healthcare programs. The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful
in businesses outside of the healthcare industry. In implementing the statute, the Office of Inspector General of the U.S. Department of Health and Services, or OIG, has issued a series of regulations, known as the &#147;safe harbors.&#148; These
safe harbors set forth provisions that, if all their applicable requirements are met, will assure healthcare providers and other parties that they will not be prosecuted under the Anti-Kickback Statute. The failure of a transaction or arrangement to

False Claims Act also allows a private individual or entity with knowledge of past or present fraud on the federal government to sue on behalf of the government to recover the civil penalties and treble damages. The U.S. Department of Justice on
behalf of the government has successfully enforced the Federal False Claims Act against pharmaceutical manufacturers. The federal suit has alleged that pharmaceutical manufacturers whose marketing and promotional practices were found to have
included the off-label promotion of drugs or the payment of prohibited kickbacks to doctors violated the FCA on the grounds that these prohibited activities resulted in the submission of claims to federal and state healthcare entitlement programs
such as Medicaid, resulting in the payment of claims by Medicaid for the off-label use of the drug which was not a use of the drug otherwise covered by Medicaid. Such manufacturers have entered into settlements with the federal government under

voluntary standards regulating the design, manufacture and labeling of and clinical trials and adverse event reporting for medical devices. Devices that comply with the requirements of a relevant directive will be entitled to bear CE conformity
marking, indicating that the device conforms with the essential requirements of the applicable directives and, accordingly, can be commercially distributed throughout the member states of the European Union, and other countries that comply with or
mirror these directives. The method for assessing conformity varies depending on the type and class of the product, but normally involves a combination of self-assessment by the manufacturer and a third-party assessment by a notified body, an
independent and neutral institution appointed by a country to conduct the conformity assessment. This third-party assessment may consist of an audit of the manufacturer&#146;s quality system and specific testing of the manufacturer&#146;s device.
Such an assessment is required for a manufacturer to commercially distribute the product throughout these countries. International Standards Organization, or ISO 9001 and ISO 13845 certifications are voluntary standards. Compliance establishes the
presumption of conformity with the essential requirements for a CE Marking. We have the authorization to affix the CE Mark to our system and to commercialize our system in the European Union for the ablation and coagulation of soft tissues during

some of which are used to fund programs to teach the procedures involved in the surgical treatment of AF, including the use of our system for such treatment. However, while we make doctors generally aware of these programs, these institutions
determine the faculty and the content of the programs. We also rely on doctors to independently inform their colleagues about these programs. We cannot assure you that a sufficient number of doctors will become aware of training programs or that

through the submission of a pre-market approval application, or PMA, before a company may market a medical device in the United States. Certain modifications to a previously marketed device, including a proposed new use or new indication for the
device, also require the submission to the FDA of either a 510(k) or PMA before such device with the modifications may be marketed. The process of obtaining these clearances and approvals can be lengthy and expensive. The PMA process is more costly,
lengthy and uncertain than the 510(k) process and requires that the device be found to be safe and effective and must be supported by extensive data, including data from preclinical studies and human clinical trials. Though less likely, a 510(k)
application may require human clinical trials as well. Because we cannot assure you that any new products, or any product enhancements, that we develop will be subject to the shorter 510(k) clearance process, significant delays in the introduction

system has been reclassified as a Class III device. This means that we would now be required to obtain a full PMA, rather than a 510(k), in order to gain FDA approval of our system for the ablation of cardiac tissue. We may appeal the FDA&#146;s

the Federal Food, Drug, and Cosmetic Act and other laws, we are prohibited from promoting our products, including our system, for off-label uses. This means that we may not make claims about the safety or effectiveness of the AtriCure bipolar
ablation system for the ablation of cardiac tissue or the treatment of AF and may not proactively discuss or provide information on the use of our system for the treatment of AF, except in certain limited scientific and other settings. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Due to these legal constraints, our sales and marketing efforts focus only on the general technical attributes and benefits of the AtriCure bipolar
ablation system and not on the use of our system for AF treatment or other cardiac uses. At the same time, we provide certain support for the use of the AtriCure bipolar ablation system in the treatment of AF that we believe is non-promotional and
therefore permitted. In particular, since our system is only being used by doctors for the treatment of AF, we train our sales force on the use of our system by cardiothoracic surgeons to treat AF, and off-label sales are included in our sales force
compensation structure. Sales personnel call on cardiothoracic surgeons, electrophysiologists, and other doctors to discuss the general attributes of our system and respond in a non-promotional manner to unsolicited requests for information from
doctors on the use of our system in the treatment of AF by providing copies of and citations to peer-reviewed journal articles and/or other training and instructional tools. In addition, medically trained clinical application specialists attend
surgical procedures to discuss the general attributes of our system and respond to unsolicited requests for information on the use of our system for the treatment of AF. We have entered into consulting agreements with prominent cardiothoracic
surgeons and electrophysiologists who assist us with, among other things, product development and clinical development. In addition, we provide financial support in the form of research and educational grants to several leading institutions in the
cardiac field, which they may use to conduct physician training programs, including programs relating to the surgical treatment of AF using our system. We also provide some guidance to physicians and medical institutions regarding what physicians
are available and qualified for training other physicians on the use of our system in the treatment of AF. We also continue to make improvements in our system which could be viewed as supporting the ablation of cardiac tissue and the treatment of
AF. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">There is a material risk that the FDA or other federal or state law enforcement authorities could determine that the nature and scope

or changed, including sales activities, arrangements with institutions and doctors, educational and training programs and other activities. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"

example, in November 2004, we received a letter from the FDA relating to certain cardiac-related information on our website in connection with the AtriCure bipolar ablation system, which we subsequently removed. There is also a possibility that we
could be enjoined from making sales of the AtriCure bipolar ablation system for any non-FDA-approved use, which effectively would bar all sales of our system until we receive FDA clearances or approval, if ever. In addition, as a result of
enforcement actions against us or our senior officers, we could be excluded from participation in government healthcare programs such as Medicare and Medicaid. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman"

complex and even minor, inadvertent irregularities in submissions can potentially give rise to claims that a statute has been violated. Any violations of these laws could result in a material adverse effect on our business, financial condition and
results of operations. For example, if we were found to be in violation of the federal False Claims Act, we would likely face significant fines and penalties and would likely be required to change substantially our sales, promotion, grant and
educational activities. There is also a possibility that we could face an injunction that would prohibit in whole or in part our current business activities, and, as a result of enforcement actions against us or our senior officers, we could be
excluded from participation in government healthcare programs such as Medicare and Medicaid. If there is a change in law, regulation or administrative or judicial interpretations, we may have to change our business practices or our existing business
practices could be challenged as unlawful, which could have a material adverse effect on our business, financial condition and results of operations. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

required to obtain permits or licensure under these laws that we do not already possess, we may become subject to substantial additional regulation or incur significant expense. Any penalties, damages, fines, curtailment or restructuring of our
operations would adversely affect our ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully or clearly interpreted by the
regulatory authorities or the courts, and their provisions are subject to a variety of interpretations and additional legal or regulatory change. Any action against us for violation of these laws, even if we successfully defend against it, could
cause us to incur significant legal expenses, divert our management&#146;s attention from the operation of our business and damage our reputation. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

FACE="Times New Roman" SIZE="2">Widespread adoption or use of the AtriCure bipolar ablation system by the medical community is unlikely to occur if doctors and hospitals do not receive sufficient reimbursement from payors for surgical treatment of
AF using our system. Currently, hospitals do not receive any additional reimbursement from the fee-for-service Medicare program, which is administered by the Centers for Medicare and Medicaid Services, or CMS, for the cost of AF treatment, or for
the cost of our system, as part of an open-heart procedure. However, doctors performing AF treatment during an open-heart surgical procedure do receive separate reimbursement for performing these AF treatments. Sole-therapy minimally invasive AF
treatment does qualify for reimbursement from the fee-for-service Medicare program allowing both doctors and hospitals to receive reimbursement for this type of AF treatment. In addition, the Medicare program has already adopted specific hospital
inpatient treatment codes describing AF treatment by ablation in sole-therapy minimally invasive procedures such as that provided through the use of the AtriCure bipolar ablation system. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Many private payors look to CMS as a guideline in setting their reimbursement policies and amounts. If CMS or other agencies decrease or limit
reimbursement payments for doctors and hospitals, this may affect coverage and reimbursement determinations by many private payors. Additionally, some private payors do not follow the Medicare guidelines and those payors may reimburse only a portion
of the cost of AF treatment or not at all. Furthermore, for some governmental payors, such as the Medicaid program, reimbursement differs from state to state, and some state Medicaid programs may not reimburse for our procedure in an adequate
amount, if at all. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">We are unable to predict all changes to the coverage or reimbursement methodologies that will be employed by private or
governmental third-party payors. We cannot be certain that under prospective payment systems and applicable fee schedules, such as those used by CMS and by many private healthcare payors, the cost of the procedures utilizing the AtriCure bipolar
ablation system will be adequately reimbursed or that it will receive reimbursement consistent with historical levels. Any denial of private or governmental third-party payor coverage or inadequate reimbursement for procedures performed using the
AtriCure bipolar ablation system could harm our business and reduce our revenue. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B>Adverse changes in payors&#146; policies toward coverage and

payors are increasingly exerting pressure on medical device companies to reduce their prices. Even to the extent that the treatment of AF using the AtriCure bipolar ablation system is reimbursed by private payors and governmental payors, adverse
changes in payors&#146; policies toward coverage and reimbursement for surgical AF treatment would also harm our ability to promote and sell the AtriCure bipolar ablation system. Payors continue to review their policies and can, without notice, deny
coverage for treatments that include the use of our product. Because each third-party payor individually approves coverage and reimbursement, obtaining these approvals may be time-consuming and costly. In addition, third-party payors may require us
to provide scientific and clinical support for the use of the AtriCure bipolar ablation system. Alternatively, government or private payors may deem the treatment of AF utilizing the AtriCure bipolar ablation system experimental or not medically
necessary and, as such, not provide coverage. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Adverse changes in coverage and reimbursement for surgical AF treatment could harm our

upon which the efficacy of our system will be measured include long-term data on the number of patients that continue to experience AF following treatment with our system and the number of patients that have serious complications resulting from AF
treatment using our system. Our clinical trials may produce limited data regarding the efficacy of our system for the treatment of AF, or may identify unexpected safety issues. We cannot provide any assurance that the data collected during our
clinical trials will be compelling to the medical community or to the FDA, because it may not be scientifically meaningful and may not demonstrate that the AtriCure bipolar ablation system is an attractive procedure when compared against data from
alternative procedures and products. In addition, the long-term effects of the AtriCure bipolar ablation system procedure are not known. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"

long-term results do not otherwise meet doctors&#146; expectations, the FDA may not approve our system for the treatment of AF, the AtriCure bipolar ablation system may not become widely adopted, and doctors may recommend alternative treatments for
their patients. Another significant factor is acute safety data on complications that occur during the treatment of AF during open-heart surgical procedures and as a sole-therapy minimally invasive treatment. </FONT></P> <P

ablation system is not safe or effective, or not as safe or effective as other treatment options or than current short-term data would suggest, the FDA may not approve our system for the treatment of AF, adoption of the use of our system for the
treatment of AF may suffer and our business would be harmed. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Even if we believe the data collected from clinical studies or clinical
experience indicates positive results, each doctor&#146;s actual experience with our system may vary. Clinical studies conducted with our system have involved procedures performed by doctors who are technically proficient. Consequently, both short-
and long-term results reported in these studies may be significantly more favorable than typical results of practicing doctors, which could negatively impact rates of adoption of the AtriCure bipolar ablation system. </FONT></P> <P

was attributable to sales in markets outside of the United States. We currently depend on third-party distributors to sell the AtriCure bipolar ablation system outside of the United States, and if these distributors underperform, we may be unable to
increase or maintain our level of international revenue. Over the long term, we intend to grow our business outside of the United States, and to do so we will need to attract additional distributors or hire direct sales personnel to expand the
territories in which we sell the AtriCure bipolar ablation system. Distributors may not commit the necessary resources to promote and sell our system to the level of our expectations. If current or future distributors do not perform adequately, or
we are unable to locate distributors in particular geographic areas, we may not realize expected long-term international revenue growth. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"

adverse consequences, including enforcement actions, fines and penalties, recalls, cessation of sales, civil and criminal prosecution, and the consequences could be disproportionate to the relative contribution of our international operations to our

States are prevalent in many of the other countries in which we sell our system, and these efforts are expected to continue. To the extent that use of an ablation device such as the AtriCure bipolar ablation system has historically received
reimbursement under a foreign healthcare payment system, if any, such reimbursement has typically been significantly less than the reimbursement provided in the United States. If coverage and adequate levels of reimbursement from governmental and

to provide an understanding of our results of operations, financial condition, and cash flows. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. The actual results may differ from

surgical devices designed to create precise lesions, or scars, in cardiac and soft tissues. Our primary product line is the AtriCure bipolar ablation system, which accounted for 94% of our revenue for the fiscal year ended December&nbsp;31, 2005,
99% of our revenue for the fiscal year ended December&nbsp;31, 2004 and 100% of our revenue for the fiscal year ended December&nbsp;31, 2003. The AtriCure bipolar ablation system consists of a compact power generator known as an ablation sensing
unit, or ASU, and several uniquely designed disposable ablation clamps that connect to the ASU, including two newly developed Isolator endoscopic ablation clamps that are specifically designed for use in sole-therapy minimally invasive procedures.
We also market the Isolator bipolar pen and the Wolf dissector, which are separate from, but complement, our system. Medical journals have described the adoption by leading cardiothoracic surgeons of the AtriCure bipolar ablation system as a
standard treatment alternative during open-heart surgical procedures to safely, rapidly and reliably create lesions in cardiac tissue to block the abnormal electrical impulses that cause atrial fibrillation, or AF, a rapid, irregular quivering of
the upper chambers of the heart. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Cardiothoracic surgeons have used the AtriCure bipolar ablation system to treat AF in over 25,000
patients since its general commercial release in the United States in January 2003. We believe that our system is currently a market leader in the surgical treatment of AF during open-heart surgical procedures and surgeons have used our system as a
sole-therapy minimally invasive treatment for AF, which is performed on patients who are not undergoing a separate open-heart procedure, on over 800 patients. We anticipate that substantially all of our sales for the foreseeable future will relate
to the AtriCure bipolar ablation system for the treatment of AF. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">From our inception in November 2000 through the first half of 2002, our
operations consisted primarily of development-stage activities, including the development of the AtriCure bipolar ablation system, raising capital, obtaining product clearances, conducting product testing and evaluations, and recruiting personnel.
After limited sales of our system in 2002, we commenced the general commercial release of our system in January 2003, generating total revenue of approximately $9.8 million for 2003, $19.2 million for 2004 and approximately $31.0 million for 2005.
We had a net loss available to common shareholders (after accrual of interest on our redeemable preferred stock) of approximately $7.1 million for 2003, approximately $9.5 million for 2004 and approximately $12.7 million for 2005. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">We currently sell the AtriCure bipolar ablation system to customers in the United States primarily through our direct sales force. We also sell our
system outside of the United States, primarily in Asia, Europe, South America, Canada and the Middle East, through distributors who pay us in U.S. dollars. To date, our sales outside of the United States have been limited, constituting approximately
8.7% of our total revenue for 2005, approximately 7.4% of our total revenue for 2004 and approximately 3.2% of our total revenue for 2003. We expect international sales to be relatively constant as a percentage of sales for the foreseeable future.
We have expanded our sales and training force in the United States from 26 employees as of December&nbsp;31, 2004 to 51 employees as of December&nbsp;31, 2005. We believe at this time our sales organization is appropriately sized and do not
anticipate significant increases in the foreseeable future. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Our future growth will depend on our ability to generate sales of the AtriCure

<FONT FACE="Times New Roman" SIZE="2">the surgical treatment of AF. Acceptance of our bipolar ablation system is dependent upon, among other factors, awareness and education of the medical
community about the surgical treatment of AF, in general, and the safety and effectiveness of the AtriCure bipolar ablation system, in particular. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"
SIZE="2">In 2001, the FDA cleared the AtriCure bipolar ablation system for the ablation and coagulation of soft tissues during certain non-cardiac-related surgical procedures, but our system has not been cleared or approved in the United States for
the ablation of cardiac tissue or for the treatment of AF. In addition, in July 2005 we received FDA clearance for our single-use disposable Isolator bipolar pen for cardiac tissue ablation. As such, we may promote this device to doctors and provide
education and training on the use of our pen device for that use. We do not believe that our AtriCure bipolar ablation system is currently being used for its FDA-cleared indications and, accordingly, substantially all of our revenue is currently
generated through the non-FDA-approved, or off-label, use of our system for the treatment of AF. While the FDA does not prevent doctors from using a product on an off-label basis, we cannot legally market a product for an off-label use. Because the
AtriCure bipolar ablation system is currently our only significant product, the sustainability of our current operations, as well as our future viability, is dependent upon the continuation of sales of our system. We believe that sole-therapy
minimally invasive treatment for AF represents the largest growth opportunity for us. If this market fails to develop, or the AtriCure bipolar ablation system is not widely adopted for use in this market, we may not achieve greater revenue or become
profitable. In order to establish the sole-therapy minimally invasive AF treatment market, the current referral practices of physicians must change. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2">In June 2005, the FDA denied 510(k) clearance (approval to market a medical device in the United States based on a device being substantially equivalent to an already cleared device) for use of our bipolar ablation
system to ablate cardiac tissue because the FDA determined that our system is not substantially equivalent to an already cleared device. The FDA has taken a position that all radio-frequency surgical clamps are not general cardiac tools because they
are specifically designed and intended for use in surgical ablation to treat AF. As such, no radio-frequency surgical clamps from any medical device company, including ours, have been cleared for cardiac ablation to date. This means that we would
now be required to gain FDA approval to market the device through the submission of a pre-market approval application, or PMA, a lengthier process, in order to gain FDA approval of our system for the cardiac indication. While we may appeal the
FDA&#146;s decision, that clearance would not eliminate the need to seek FDA approval through a separate PMA for the use of our system to treat AF. After conducting necessary clinical trials, we intend to seek FDA approval as early as 2009 for the
use of our system to treat AF, which we view as our market opportunity. If lack of FDA clearance or approval of our system for the treatment of AF were to prevent sales of our system, not only would we no longer receive revenue from the sale of our
system, but we also would require significant financing to conduct clinical trials and to sustain our operations until such time as sales could resume. We cannot assure you that we can obtain these FDA approvals, that we would have, or could raise,
sufficient financial resources to sustain our operations pending FDA approval, or that, if and when the required approvals are obtained, there will be a market for the AtriCure bipolar ablation system. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Our costs and expenses consist of cost of revenue, research and development expenses and selling, general and administrative expenses. Cost of revenue
consists principally of the cost of purchasing materials and manufacturing our products. Research and development expenses consist principally of expenses incurred with respect to internal and external research and development activities and the
conduct of clinical trials. With the FDA&#146;s authorization, we have begun the RESTORE-SR clinical trial relating to the use of the AtriCure bipolar ablation system to treat AF during open-heart surgery. A total of 29 patients have been enrolled
in the clinical trial as of February&nbsp;28, 2006, approximately 12.8% of the patients required for this multicenter, 226-patient clinical trial. We have also obtained FDA approval to conduct the RESTORE-SR II clinical study to evaluate the
feasibility of using our system as a sole-therapy minimally invasive treatment for AF. This feasibility study is expected to enroll 25 patients at 5 leading US centers. A total of 17 patients have been treated in the study as of March&nbsp;2, 2006
and we anticipate that enrollment and treatment of all 25 patients will be completed during the second quarter of 2006. Selling, general and administrative expenses consist principally of costs associated with our sales and administrative functions,
accounting and legal fees and educational grants to medical institutions. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

that we are experiencing a negative impact on our business from newspaper articles published in December 2005 and February 2006 relating to, among other things, concerns of conflicts of interest between the Cleveland Clinic and us, our compliance
with FDA regulations for medical device reporting, and concerns that certain of our consultants who are involved with clinical studies of our products failed to adequately disclose their financial relationships with us. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In the wake of these articles, certain educational activities involving our products at the Cleveland Clinic and the University of Cincinnati were

who has conducted clinical studies on the use of our system to treat AF and published articles relating to such studies, has reduced his involvement in educational activities at the University of Cincinnati and he is recovering from back surgery. In
light of Dr.&nbsp;Wolf&#146;s diminished involvement with educational activities and this unfavorable publicity, we are uncertain as to whether the educational activities involving our products at the University of Cincinnati will resume their
previous levels. We also understand that the University of Cincinnati has initiated an internal review to validate the data obtained from two clinical studies involving our system that were conducted by Dr.&nbsp;Wolf. We cannot assure you that this
data will be validated and we cannot predict with certainty the effect that any failure to validate this data would have on us. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Because
these articles relate to the validity of important clinical data on the use of our system and involve Dr.&nbsp;Wolf and two of the pioneering institutions which have been proponents and investigators of our system, some current and potential

or similar unfavorable publicity will not adversely impact future clinical studies involving our products or adversely impact our current or future submissions to the FDA. </FONT></P> <P

that were sold by selling shareholders. These share amounts reflect a 1-for-3.8 reverse split of our capital stock that was effected on July&nbsp;27, 2005. In connection with the offering, all of the 6,012,020 outstanding shares of preferred stock
were converted into 6,012,020 shares of common stock. Proceeds to us from the offering, after deducting underwriting discounts, commissions and offering expenses, were $43.2 million. Offering expenses were approximately $3.1 million. </FONT></P> <P

</TABLE> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B>Revenue.</B> Total revenue increased approximately $11.8 million or 61.6%, from approximately
$19.2 million in 2004 to approximately $31.0 million in 2005. The increase was primarily attributable to an increase of approximately 65% in the number of units sold of our bipolar ablation clamps, and new product launches, such as the Isolator
bipolar pen. The increase in units sold of our previously existing product lines contributed approximately $10.7 million of the total increase in sales, while the addition of the new bipolar pen product and other revenue contributed approximately
$1.0 million to the increase in revenue. Though our domestic and international sales were both favorably impacted by increases in average selling prices, the increase in our sales mix of lower priced international sales as a percentage of total
sales resulted in a modest worldwide increase in our average selling price year over year, contributing approximately $0.1 million to the overall revenue increase. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2"><B>Cost of revenue.</B> Cost of revenue increased approximately $2.9 million, from approximately $5.2 million in 2004 to approximately $8.1 million in 2005. This increase resulted primarily from increased sales of
products, additional depreciation associated with generators and cryo-units that are loaned at no cost to hospitals, a $193,000 increase in our obsolescence reserve, and a $266,000 write-off related to production equipment for discontinued products.
These increases in cost of revenue were partially offset by our lower average cost per unit as a result of our third quarter acquisition of Enable Medical Corporation, the manufacturer of our single-use disposable ablation clamps. As a percentage of
revenue, cost of revenue decreased from 27% in 2004 to 26% in 2005 due to our lower average cost per unit as discussed above. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

 <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B>Research and development expenses.</B> Research and development expenses increased approximately $4.7
million, from approximately $4.4 million in 2004 to approximately $9.1 million in 2005. The increase was primarily attributable to the addition of 25 full-time research and development personnel, including 13 former Enable employees, the expansion
of our research and development activities to increase our product offerings and the expansion of our clinical trial activities. Our product development activities included projects to extend and improve the AtriCure bipolar ablation system, develop
our new Isolator endoscopic ablation clamps, create new enabling devices such as new dissection, guidance and ablation tools, and research for new technologies. As a percentage of total revenue, research and development expenses increased from 23%
in 2004 to 29% in 2005 due to increased spending on new product initiatives, expanded clinical trials and the addition of personnel. Research and development costs are expected to increase in 2006 both in absolute dollars and as a percentage of
revenue primarily as a result of costs associated with the continued expansion of product development initiatives and clinical trials. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"
SIZE="2"><B>Selling, general and administrative expenses.</B> Selling, general and administrative expenses increased approximately $9.4 million, from approximately $15.2 million in 2004 to approximately $24.6 million in 2005. The increase was
primarily attributable to an increase in headcount-related charges of approximately $6.7 million, an increase in educational grants to medical institutions of approximately $1.0 million, and an increase in general corporate expenditures of
approximately $1.7 million. The increase in headcount-related charges is primarily attributable to the acquisition of Enable and the addition of sales personnel who call on doctors to discuss the general attributes of our system, and respond in a
non-promotional manner to unsolicited requests for information from physicians on the use of our system in the treatment of AF. As a percentage of total revenue, selling, general and administrative expenses remained relatively constant at
approximately 79% for 2004 and 2005. Selling, general and administrative costs are expected to increase in 2006 in absolute dollars and as a percentage of revenue primarily as a result of increased costs associated with sales and marketing efforts

expense decreased approximately $1.6 million, from approximately $3.9 million in 2004 to approximately $2.3 million in 2005. The decrease was attributable to the conversion of all shares of preferred stock into common stock upon the closing of our

$308,000, from approximately $106,000 in 2004 to approximately $414,000 in 2005, due to the increased cash and cash equivalents resulting from the proceeds of our August 2005 initial public offering. The increase was partially offset by the interest

</TABLE> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B>Revenue</B>. Revenue increased approximately $9.4 million, from approximately $9.8 million in
2003 to approximately $19.2 million in 2004. The increase was primarily attributable to an increase of approximately 46% in the volume of units of our previously existing product line sold domestically and internationally and the addition of new
products. The increase in units sold of our previously existing product line contributed approximately $4.8 million of the total increase in sales, while the addition of new products contributed approximately $5.4 million to the increase in revenue.
While our average domestic selling price marginally increased in 2004 over 2003, the increase in lower priced international sales as a percentage of total sales resulted in a marginal decline in our overall average selling price year over year. This
marginal decline in our selling price partially offset the overall revenue increase by approximately $0.8 million. We obtained numerous new accounts, as the AtriCure bipolar ablation system was reviewed in industry journals and doctors more widely
adopted the use of our system. Included in total revenue is approximately $211,000 of commissions for 2004 from sales of certain cryothermy products. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2"><B>Cost of revenue</B>. Cost of revenue increased approximately $2.6 million, from approximately $2.6 million in 2003 to approximately $5.2 million in 2004 reflecting the approximate 100% increase in total units sold
in 2004 as compared to 2003. Cost stability in our existing system and similar margin pricing strategies on our new product lines resulted in an increase in cost of revenue compared to 2003 consistent with the growth in total revenue since, as a
percentage of revenue, cost of revenue remained the same at 27% for 2003 and 2004. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B>Research and development expenses</B>. Research and
development expenses increased approximately $1.9 million, from approximately $2.5 million in 2003 to approximately $4.4 million in 2004. The increase was primarily attributable to the hiring of an additional 9 engineers in 2004, the expansion of
our research and development activities to increase our product offerings and the expansion of our clinical trials. Our product development activities include projects to extend and improve the existing system, develop a new device platform, create
new enabling devices such as new dissection, guidance and ablation tools, and research new technologies. As a percentage of total revenue, research and development expenses decreased from 26% in 2003 to 23% in 2004, due to the more rapid growth of
revenue. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

increased approximately $7.2 million, from approximately $8.0 million in 2003 to approximately $15.2 million in 2004. The increase was primarily attributable to an increase in headcount-related charges of approximately $4.2 million, an increase in
facilities-related charges of approximately $0.9 million, and an increase in non-cash charges of $1.0 million associated with certain option grants. Headcount-related charges were primarily attributable to the rapid expansion of our sales force to
meet our growing market. These additional sales personnel call on doctors to discuss the general attributes of our system, and respond in a non-promotional manner to unsolicited requests for information from doctors on the use of our system in the
treatment of AF. As a percentage of total revenue, selling, general and administrative expenses decreased slightly from 82% in 2003 to 79% in 2004. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"
SIZE="2">In 2004, we recorded a compensation charge of approximately $327,000 for stock options issued to employees that, subsequent to their issuance, were determined to have been issued with exercise prices below market value. The market value of
these options was determined by applying a multiplier to our projected revenue. This value was then reduced by approximately 20% to reflect the illiquidity of the options. Given the fact that we are in a rapid growth phase, but are still
unprofitable, we determined that applying a multiplier, determined by comparison to other rapidly growing healthcare companies of generally similar size to us, was the most appropriate valuation method. </FONT></P> <P

to a net loss of $12.7 million and increases in inventory and prepaid expenses of $0.2 million and $0.7 million, respectively, as we increased our revenue, partially offset by adjustments for non-cash charges related to stock-based compensation of
$0.7 million, depreciation and amortization of $1.6 million, preferred stock interest of $2.3 million and increases in payables and accrued liabilities of $0.6 million due to our increase in operating expenses. Net cash used in operations in 2004
was primarily attributable to a net loss of $9.5 million and increases in accounts receivable and inventory balances of $1.9 million and $0.4 million, respectively, as we increased our revenue, partially offset by adjustments for non-cash charges
related to stock-based compensation of $1.0 million, depreciation of $1.0 million, preferred stock interest of $3.9 million and increases in payables and accrued liabilities of $2.4 million due to our increase in operating expenses. Net cash used in

$14.8 million in 2005, $1.5 million in 2004 and $1.3 million in 2003. For each of these periods, cash used in investing activities reflected purchases of property and equipment and, in 2005, the purchase of approximately $6.4 million of short-term

common stock related to our initial public offering and borrowings under our Lighthouse credit facility discussed below, which were partially offset by payments made on our debt and lease obligations. For each of these periods, cash flows provided
by financing activities also reflected the issuance of common stock related to stock option exercises.</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B>Credit facility.</B> We entered
into a $5.0 million credit facility on March&nbsp;8, 2005 with Lighthouse Capital Partners V, L.P. for working capital requirements. Outstanding borrowings under the facility bear interest at the prime rate plus 1.75% and our ability to draw down
funds under this facility terminated upon our initial public offering. Under the terms of the facility, we are required to pay any monthly installments of interest only through August 2005 and monthly installments of principal and interest
thereafter, in addition to a fee due at maturity on September&nbsp;1, 2009 equal to 15% of the aggregate amount borrowed under the credit facility, with prepayment in whole allowed at any time without penalty. As of December&nbsp;31, 2005, there was
approximately $1.4 million outstanding under this facility. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In connection with establishing this facility, we granted Lighthouse a warrant
to purchase 55,208 shares of our common stock, or shares into which such series of stock is converted, at a price of $11.29 per share. In valuing this warrant, we relied upon recognized option pricing models. The valuations used closed-form models,
such as the Black-Scholes-Merton model and the Bjerksund and Stensland approximation model, as well as the lattice form binomial models. The time to expiration of the warrant ranges between 1.0 year and 7.0 years, and we assumed values for
volatility and expected dividend yield equal to 35.0% and 0%, respectively. The risk-free discount rate used ranged between 3.23% and 4.22%. Utilizing these inputs in the option-pricing models for the warrant, a value for the warrant of
approximately $3.91 per underlying share was determined, which has been recorded as deferred financing costs and will be amortized over the term of the credit facility. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

acquisitions and joint ventures, the rate of market acceptance of our current and future products, the resources we devote to developing and supporting our products, future expenses to expand and support our sales and marketing efforts, costs
relating to changes in regulatory policies or laws that affect our operations and costs of filing, prosecuting, defending and enforcing our intellectual property rights. We expect to increase capital expenditures consistent with our anticipated
growth in research and development, manufacturing, infrastructure and personnel. In addition, we acquired Enable contemporaneously with the closing of our initial public offering for a net purchase price of $6.4 million. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">We believe that our current cash and cash equivalents, along with the cash we expect to generate from operations, will be sufficient to meet our
anticipated cash needs for working capital and capital expenditures for at least the next 12 months. If these sources of cash are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt securities or obtain
a credit facility. The sale of additional equity or convertible debt securities could result in dilution to our stockholders. If additional funds are raised through the issuance of debt securities, these securities could have rights senior to those
associated with our common stock and could contain covenants that would restrict our operations. Additional financing may not be available at all, or in amounts or terms acceptable to us. If we are unable to obtain this additional financing, we may
be required to reduce the scope of our planned research and development and selling and marketing efforts. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

Involving Stock Compensation, and related interpretations. Prior to January&nbsp;1, 2006, we followed the disclosure-only provisions of Statement of Financial Accounting Standards (&#147;SFAS&#148;) No.&nbsp;123, Accounting for Stock Based

the Wolf dissector. Pursuant to our standard sales terms, revenue is recognized when title to the goods and risk of loss transfer to customers and there are no remaining obligations that will affect the customer&#146;s final acceptance of the sale.
Our standard sales terms define the transfer of title and risk of loss to occur upon shipment to the respective customer. We maintain no post-shipping obligations to the recipients of the products. No installation, calibration or testing of this
equipment is performed by us subsequent to shipment to the customer in order to render it operational. Product revenue includes shipping revenue of approximately $141,000 in 2005, $87,000 in 2004 and $43,000 in 2003. Cost of freight is included in
cost of goods sold. We sell our products through a direct and indirect sales force. Sales terms are consistent for both end-users and distributors, with terms generally not exceeding 120 days. Customers and distributors generally have no right of
return. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">We comply with SEC Staff Accounting Bulletin No.&nbsp;101, Recognition in Financial Statements, or SAB 101, as amended by SAB 104.
SAB 101 sets forth guidelines on the timing of revenue recognition based upon factors such as passage of title, installation, payment terms and ability to return products. We recognize revenue when all of the following criteria are met: persuasive
evidence that an arrangement exists; delivery of the products or services has occurred; the selling price is fixed or determinable; and collectibility is reasonable assured. </FONT></P> <P

or considerations. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B><I>Inventory Valuation.</I></B> Inventories are stated at the lower of cost or market using the first-in, first-out,
or FIFO, cost method and consist of raw materials, work in process and finished goods. Reserves are estimated for excess, slow-moving and obsolete inventory, as well as inventory with a carrying value in excess of its net realizable value.
Write-offs are recorded when the product is destroyed. We review inventory on hand at least quarterly and record provisions for excess and obsolete inventory based on several factors including current assessment of future product demand, anticipated
release of new products into the market, historical experience and product expiration. Our industry is characterized by rapid product development and frequent new product introductions. Uncertain timing of product approvals, variability in product
launch strategies, product recalls and variation in product utilization all impact the estimates related to excess and obsolete inventory. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"

</B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In November 2004, the FASB issued SFAS No.&nbsp;151 entitled &#147;Inventory Costs.&#148; This Statement amends the guidance in ARB
No.&nbsp;43, &#147;Inventory Pricing,&#148; to clarify the accounting for abnormal amounts of idle facility expense, freight handling costs and wasted material (spoilage). The provisions of this Statement will be effective for inventory costs
incurred during fiscal years beginning after June&nbsp;15, 2005. We have not yet determined the impact that adopting SFAS No.&nbsp;151 will have on our financial position and results of operations. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In December 2004, the FASB issued a revision to SFAS 123, &#147;Share-Based Payment&#148; (&#147;SFAS 123(R)&#148;). The revision requires all entities
to recognize compensation expense in an amount equal to the fair value of share-based payments granted to employees. SFAS 123(R) eliminates the alternative method of accounting for employee share-based payments previously available under APB
No.&nbsp;25 (&#147;APB 25&#148;). In April 2005, the SEC delayed the effective date of SFAS 123(R) to fiscal years beginning after June&nbsp;15, 2005. As a result, SFAS 123(R) will be effective for us beginning in the first quarter of fiscal 2006.
We expect this standard to have a significant impact on the statements of operations and statements of cash flows. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In March 2005, the FASB
issued FASB Interpretation No.&nbsp;47, &#147;Accounting for Conditional Asset Retirement Obligations&#148; (&#147;FIN 47&#148;). This Interpretation clarifies that an entity is required to recognize a liability for the fair value of a conditional
asset retirement obligation when incurred if the liability&#146;s fair value can be reasonably estimated. The provisions of this Interpretation were effective for calendar-year companies no later than the end of fiscal years ending after
December&nbsp;31, 2005. The adoption of FIN 47 did not have a material impact on our financial statements. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In May 2005, the FASB issued
SFAS 154, &#147;Accounting Changes and Error Corrections&#151;A Replacement of Accounting Principles Board (APB) Opinion No.&nbsp;20 and SFAS 3.&#148; SFAS 154 requires retrospective application to prior periods&#146; financial statements for a
change in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. Additionally, retrospective application is not required when explicit transition requirements specific
to newly adopted accounting principles exist. Retrospective application requires the cumulative effect of the change on periods prior to those presented to be reflected in the carrying amounts of assets and liabilities as of the beginning of the
first period presented and the offsetting adjustments to be recorded to opening retained earnings. SFAS 154 retains the guidance contained in APB No.&nbsp;20 for reporting both the correction of an error in previously issued financial statements and
a change in accounting estimate. SFAS 154 will become effective for accounting changes and corrections of errors made in fiscal years beginning after December&nbsp;15, 2005. We are required to adopt the provisions of SFAS 154, as applicable,
beginning in the first quarter of fiscal 2006. The adoption of SFAS No.&nbsp;154 is not expected to have a material impact on our financial statements. </FONT></P> <P STYLE="font-size:18px;margin-top:0px;margin-bottom:0px">&nbsp;</P>

we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over
financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Company&#146;s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. </FONT></P> <P

America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein. </FONT></P> <P

FACE="Times New Roman" SIZE="2"><B><I>Nature of the Business&#151;</I></B>AtriCure, Inc. (the &#147;Company&#148;) was incorporated in the State of Delaware on October&nbsp;31, 2000, as a spin-off of Enable Medical Corporation, to focus on the
surgical treatment of atrial fibrillation. Atrial fibrillation (&#147;AF&#148;) is a rapid, irregular quivering of the upper chambers of the heart. The Company sells its medical devices to hospitals and medical clinics both in the United States of
America and internationally. International sales were approximately $2.7 million, $1.4 million, and $0.3 million in 2005, 2004, and 2003, respectively. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2"><B><I>Principles of Consolidation&#151;</I></B>The consolidated financial statements include the accounts of the Company and its subsidiary. Intercompany accounts and transactions are eliminated. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B><I>Cash and Cash Equivalents&#151;</I></B>The Company considers highly liquid investments with maturities of three months or less at the date of
acquisition as cash equivalents in the accompanying financial statements. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B><I>Short-Term Investments&#151;</I></B>The Company places its
investments primarily in U.S. Government securities, corporate notes and commercial paper. The Company classifies all investments as available-for-sale. Such investments are recorded at fair value, with unrealized gains and losses recorded as a
separate component of stockholders&#146; equity (deficit). The Company recognizes gains and losses when these securities are sold using the specific identification method. </FONT></P> <P
STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2"><B><I>Revenue Recognition&#151;</I></B>Revenues are generated primarily from the sale of the Company&#146;s disposable Isolator ablation clamps, the
Isolator bipolar pen and the Wolf dissector. Pursuant to the Company&#146;s standard sales terms, revenue is recognized when title to the goods and risk of loss transfer to customers and there are no remaining obligations that will affect the
customer&#146;s final acceptance of the sale. The Company&#146;s standard sales terms define the transfer of title and risk of loss to occur upon shipment to the respective customer. The Company maintains no post-shipping obligations to the
recipients of the products. No installation, calibration or testing of this equipment is performed by the Company subsequent to shipment to the customer in order to render it operational. Product revenue includes shipping revenue of approximately
$141,000, $87,000 and $43,000 in 2005, 2004, and 2003, respectively. Cost of freight is included in cost of goods sold. The Company sells its products through a direct and indirect sales force. Sales terms are consistent for both end-users and
distributors, with terms generally not exceeding 120 days. Customers and distributors generally have no right of return. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">The Company
complies with the Securities and Exchange Commission (&#147;SEC&#148;) Staff Accounting Bulletin No.&nbsp;101, &#147;Recognition in Financial Statements&#148; (&#147;SAB 101&#148;), as amended by SAB 104. SAB 101 sets forth guidelines on the timing
of revenue recognition based upon factors such as passage of title, installation, payment terms and ability to return products. The Company recognizes revenue when all of the following criteria are met: (i)&nbsp;persuasive evidence that an
arrangement exists; (ii)&nbsp;delivery of the products and/or services has occurred; (iii)&nbsp;the selling price is fixed or determinable; and (iv)&nbsp;collectibility is reasonably assured. </FONT></P> <P

Company&#146;s product. These generators and cryo-units are depreciated over three years. The three year life reflects the fact that the generators and cryo-units are run by internal computers and are programmed with software to regulate the power
to the ablation clamps. As they are most similar to a computer, and the tolerance for imprecision is extremely low due to the nature of the work they perform, the Company anticipates that the estimated useful life cycle of these units will be
approximately three years. Such depreciation is included in cost of sales. The total of such depreciation was approximately $777,000, $543,000, and $225,000 in 2005, 2004 and 2003, respectively. </FONT></P> <P

and the tax basis of the Company&#146;s assets and liabilities. Deferred taxes are measured using provisions of currently enacted tax laws. A valuation allowance against deferred tax assets is recorded when it is more likely than not that such
assets will not be fully realized. Tax credits are accounted for as a reduction of income taxes in the year in which the credit originates. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"
SIZE="2">The Company&#146;s estimate for the valuation allowance for deferred tax assets requires it to make significant estimates and judgments about its future operating results. The Company&#146;s ability to realize the deferred tax assets
depends on its future taxable income as well as limitations on their utilization. A deferred tax asset is reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized prior to
its expiration. The projections of the Company&#146;s operating results on which the establishment of a valuation allowance is based involve significant estimates regarding future demand for the Company&#146;s products, competitive conditions,
product development efforts, approvals of regulatory agencies, and product cost. If actual results differ from these projections, or if the Company&#146;s expectations of future results change, it may be necessary to adjust the valuation allowance.

estimate the fair value of freely tradable, fully transferable options without vesting restrictions, which significantly differ from the Company&#146;s stock option awards. These models also require subjective assumptions, including expected time to

proprietary manufacturing technology, which is being amortized on a straight-line basis over 5 years. Amortization expense was approximately $83,000 in 2005. The proprietary manufacturing technology was valued based on Enable&#146;s unique ability
to manufacture the products to meet the Company&#146;s close tolerance specifications for surgical products. Enable developed an expertise in plating, mold, adhesive, and assembly technology that permitted it to be the sole supplier to the Company.
The Company has utilized the income approach in conjunction with the excess earnings approach to value the cash flow attributable to the proprietary manufacturing technology. The Company has identified the product line revenues and the relevant
costs and expenses and deducted the required returns on other contributing assets from the free cash flows, deriving the residual cash flows generated from the proprietary manufacturing technology assets, to which a discount rate was applied to
determine a present value. Future amortization expense related to these intangible assets will be approximately $214,000 in 2006-2009, and $131,000 in 2010. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT

FACE="Times New Roman" SIZE="2">In March 2005, the Company entered into a credit facility with Lighthouse Capital Partners V, L.P. of up to $5,000,000, to be drawn down by the earlier of an initial public offering of common stock and
September&nbsp;1, 2005. This credit facility is secured by substantially all of the Company&#146;s assets, excluding intellectual property. The interest rate for any amounts drawn down is the prime rate plus 1.75% fixed and determined on the date of
the draw down. For all amounts drawn down, the interest rate is 8.0%. Under the credit facility, the Company was required to pay monthly installments of interest only through August 2005 and monthly installments of principal and interest thereafter,
in addition to a fee due at maturity on September&nbsp;1, 2009 equal to 15% of the aggregate amount borrowed under the credit facility, with prepayment in whole allowed at any time without penalty. As of December&nbsp;31, 2005, there was
approximately $1.4 million outstanding under this facility. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">In addition, the facility required the Company to issue to Lighthouse a
warrant to purchase 55,208 shares of common stock at an exercise price of $11.29 per share. The warrant is exercisable at any time until August&nbsp;10, 2006. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
FACE="Times New Roman" SIZE="2">In connection with establishing this facility, the Company granted Lighthouse a warrant to purchase 55,208 shares of its common stock, or shares into which such series of stock is converted, at a price of $11.29 per
share. In valuing this warrant, the Company relied upon recognized option pricing models. The valuations used closed-form models, such as the Black-Scholes-Merton model and the Bjerksund and Stensland approximation model, as well as the lattice form
binomial models. The time to expiration of the warrant ranges between 1.0 year and 7.0 years, and the Company assumed values for volatility and expected dividend yield equal to 35.0% and 0%, respectively. The risk-free discount rate used ranged
between 3.23% and 4.22%. Utilizing these inputs in the option-pricing models for the warrant, a value for the warrant of approximately $3.91 per underlying share was determined, which has been recorded as deferred financing costs and will be
amortized over the term of the credit facility. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Maturities under this facility for the next five fiscal years are as follows: </FONT></P>

fee of $966,000, payable in fourteen monthly installments. If UST has not completed its development services within fourteen months, the Company will be required to pay UST the direct costs incurred by it for the following six months in connection
with continuing to render development services. The Company is also required to pay UST royalties of 4% of the net sales of the HIFU system, up to a maximum amount of $15 million in royalties during the royalty term. In addition, the Company is
required to make certain license and maintenance payments to UST for the sublicenses granted to it under the terms of this agreement. The Company may terminate this agreement at any time by giving notice to UST. UST may terminate this agreement if
the Company fails to timely commercialize the HIFU system or if the Company fails to timely pursue FDA approval or clearance of the HIFU system. Under the terms of this agreement, the Company has certain indemnification obligations to UST for its
breach of this agreement. In order to commercialize this HIFU system, the Company may be required to license additional intellectual property from third parties. The Company cannot assure you that it will be able to license this technology on
commercially reasonable terms, if it all. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2"><B><I>Royalty Obligation </I></B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px; text-indent:4%"><FONT

3.99% and no dividends during the expected term. The values attributable to these options have been amortized over the service period on a graded vesting method and the vested portion of these options was re-measured at each vesting date.

&#147;Inventory Pricing,&#148; to clarify the accounting for abnormal amounts of idle facility expense, freight handling costs and wasted material (spoilage). The provisions of this Statement will be effective for inventory costs incurred during
fiscal years beginning after June&nbsp;15, 2005. The Company has not yet determined the impact that adopting SFAS No.&nbsp;151 will have on its financial position and results of operations. </FONT></P> <P

to recognize compensation expense in an amount equal to the fair value of share-based payments granted to employees. SFAS 123(R) eliminates the alternative method of accounting for employee share-based payments previously available under APB
No.&nbsp;25 (&#147;APB 25&#148;). In April 2005, the SEC delayed the effective date of SFAS 123(R) to fiscal years beginning after June&nbsp;15, 2005. As a result, SFAS 123(R) will be effective for the Company beginning in the first quarter of
fiscal 2006. The Company expects this standard to have a significant impact on the statements of operations and statements of cash flows. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"

the fair value of a conditional asset retirement obligation when incurred if the liability&#146;s fair value can be reasonably estimated. The provisions of this Interpretation were effective for calendar-year companies no later than the end of
fiscal years ending after December&nbsp;31, 2005. The adoption of FIN 47 did not have a material impact on the Company&#146;s financial statements. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman"

consent of such Underwriter, such Underwriter agrees to indemnify and hold harmless the Company, any Selling Stockholder and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence,

shall be liable for any settlement of any Proceeding effected without its written consent if (i)&nbsp;such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii)&nbsp;such

<U>Insider Information</U>. Wolf agrees that as a result of the relationship established hereunder with AtriCure, Wolf may periodically possess Confidential Information that is considered to be &#147;material&#148; and &#147;non-public&#148;
information. The term &#147;material&#148; is defined to be information that a reasonable investor would consider important in making an informed investment decision. The term &#147;non-public&#148; means not made generally known by press release,
conference call open to the public, or in a filing with the Securities and Exchange Commission. Wolf also understands that AtriCure has adopted an insider trading policy that contains certain black-out periods for holders of material non-public
information. That black-out period starts on the first day of the last month of a fiscal quarter and ends two full days following the release of earnings or other material non-public financial information. Wolf agrees not to buy, sell, pledge or
otherwise trade, in AtriCure&#146;s stock or options, or enter into any transaction having the same economic effect, while in possession of material non-public Confidential Information without pre-clearing such trades with AtriCure&#146;s Chief
Financial Officer. Wolf understands that this Agreement further requires that Wolf not disclose such Confidential Information to anyone until it otherwise becomes publicly available. </FONT></P> <P
