We offer our proprietary Epoch Solution, an advanced remote robotic navigation system for use in a hospital’sinterventional surgical suite, or “interventional lab”. We believe the Epoch Solution revolutionizes the treatment of arrhythmias and coronary artery disease byenabling enhanced safety, efficiency and efficacy for catheter-based, or interventional, procedures. The Epoch Solution is comprised of the Niobe ES RoboticMagnetic Navigation System (“Niobe ES system”), Odyssey Information Management Solution (“Odyssey Solution”), and the Vdrive Robotic NavigationSystem (“Vdrive system”). We believe that our technology represents an important advance in the ongoing trend toward fully digitized, integrated andautomated interventional labs and provides substantial, clinically important improvements over manual interventional methods, which often result in long andunpredictable procedure times with suboptimal therapeutic outcomes. We believe that our technology represents an important advance supporting efficient andeffective information management and physician collaboration. The core elements of our technology, especially the Niobe ES system, are protected by anextensive patent portfolio, as well as substantial expertise and trade secrets.Our Niobe ES system is the latest generation of the Niobe Robotic Magnetic Navigation System (“Niobe system”), which allows physicians to moreeffectively navigate proprietary catheters, guidewires and other delivery devices, both our own and those we are co-developing through strategic alliances,through the blood vessels and chambers of the heart to treatment sites in order to effect treatment. This is achieved using computer-controlled, externallyapplied magnetic fields that precisely and directly govern the motion of the internal, or working, tip of the catheter, guidewire or other interventional devices.We believe that our Niobe ES system represents a revolutionary technology in the interventional lab, bringing precise remote digital instrument control andprogrammability to the interventional lab, and has the potential to become the standard of care for a broad range of complex cardiology procedures.The Niobe system is designed primarily for use by interventional electrophysiologists in the treatment of arrhythmias and approximately 1% of usage isby interventional cardiologists in the treatment of coronary artery disease. To date the significant majority of the Stereotaxis installations worldwide areintended for use in electrophysiology. The Niobe system is designed to be installed in both new and replacement interventional labs worldwide. Current andpotential purchasers of our Niobe system include leading research and academic hospitals as well as community and regional medical centers around theworld.The Niobe system has been used in more than 66,000 procedures and is supported by more than 200 peer-reviewed publications in leading medicaljournals such as PACE, Europace, the Journal of the American College of Cardiology and the Journal of Interventional Cardiac Electrophysiology. Niobesystem revenue represented 23%, 26%, and 19% of revenue for the years ended December 31, 2013, 2012, and 2011, respectively.Stereotaxis has also developed the Odyssey Solution which provides an innovative enterprise solution for integrating, recording and networkinginterventional lab information within hospitals. The Odyssey Solution consists of two lab solutions including Odyssey Vision and the Odyssey Cinemasystem. Odyssey Vision consolidates all of the lab information from multiple sources, freeing doctors from managing complex interfaces during patienttherapy for optimal procedural and clinical efficiency. The Odyssey Cinema system is an innovative solution delivering synchronized content targeted toimprove care, enhance performance, increase referrals and market services. This tool includes an archiving capability that allows clinicians to store andreplay entire procedures or segments of procedures. This information can be accessed from locations throughout the hospital local area network and over theInternet from anywhere with sufficient bandwidth. The Odyssey Solution may be acquired either as part of the Epoch Solution or on a stand-alone basis forinstallation in interventional labs and other locations where clinicians desire improved clinical workflows and related efficiencies. Odyssey system revenuerepresented 10%, 14%, and 18% of revenue for the years ended December 31, 2013, 2012, and 2011, respectively. 2Our Vdrive system provides navigation and stability for diagnostic and therapeutic devices designed to improve interventional procedures. The Vdrivesystem complements the Niobe ES system control of therapeutic catheters for fully remote procedures and enables single-operator workflow and is sold as twooptions, the Vdrive system and the Vdrive Duo system. In addition to the Vdrive system and the Vdrive Duo system, we also manufacture and marketvarious disposable components (V-Loop, V-Sono, V-CAS, and V-CAS Deflect) which can be manipulated by these systems.We promote the full Epoch Solution in a typical hospital implementation, subject to regulatory approvals or clearances. The full Epoch Solutionimplementation requires a hospital to agree to an upfront capital payment and recurring payments. The upfront capital payment typically includes equipmentand installation charges. The recurring payments typically include disposable costs for each procedure, equipment service costs beyond warranty period, andsoftware licenses. In hospitals where the full Epoch Solution has not been implemented, equipment upgrade or expansion can be implemented upon purchasingof the necessary upgrade or expansion.Not all products have and/or require regulatory clearance in all of the markets we serve. Please refer to “Regulatory Approval” in Item 1 for a descriptionof our regulatory clearance, licensing, and/or approvals we currently have or are pursuing.As of December 31, 2013, we had approximately $6.8 million of backlog, consisting of outstanding purchase orders and other commitments for thesesystems. We had backlog of approximately $8.9 million and $20 million as of December 31, 2012 and 2011, respectively. Of the December 31, 2013backlog, we expect approximately 75% to be recognized as revenue over the course of 2014. There can be no assurance that we will recognize such revenue inany particular period or at all because some of our purchase orders and other commitments are subject to contingencies that are outside our control. Theseorders and commitments may be revised, modified or canceled, either by their express terms, as a result of negotiations or by project changes or delays. Inaddition, the sales cycle for the Epoch Solution is lengthy and generally involves construction or renovation activities at customer sites. Consequently,revenues and/or orders resulting from sales of our Epoch Solution can vary significantly from one reporting period to the next.We have alliances with Siemens AG Medical Healthcare, Philips Healthcare and Biosense Webster, a subsidiary of Johnson & Johnson. Through thesealliances, we integrate our Niobe system with Siemens’ and Philips’ market-leading cath lab imaging systems and Biosense Webster’s 3D catheter locationsensing technology. The Biosense alliance also provides development of disposable interventional devices, coordination of marketing and sales efforts in orderto continue to introduce new enhancements around the Niobe system, and non-exclusive commercialization of the Odyssey Solution to Biosense customers inthe electrophysiology field. The Siemens and Philips alliances provide for coordination of our sales and marketing efforts with those of our alliance partners tofacilitate co-marketing of integrated systems.BACKGROUNDWe have focused our clinical and commercial efforts on applications of the Epoch Solution primarily in electrophysiology procedures for the treatmentof arrhythmias and secondarily in complex interventional cardiology procedures for the treatment of coronary artery disease.The rhythmic beating of the heart results from the generation and transmission of electrical impulses. When these electrical impulses are mistimed oruncoordinated, the heart fails to function properly, resulting in complications that can range from fatigue to stroke or death. Over 4.3 million people in the U.S.currently suffer from the resulting abnormal heart rhythms, which are known as arrhythmias. Electrophysiology is a fast-growing clinical specialty focusedon the treatment of cardiac arrhythmias which can occur in any chamber of the heart. Electrophysiologists typically treat patients suffering from cardiacarrhythmias with a combination of drug therapy and/or interventional catheter ablation of cardiac tissue to interrupt aberrant electrical signals. Reimbursementfor interventional catheter ablation has been stable in most markets with increasing governmental awareness of the impact of the disease state upon nationalhealthcare programs. 3Interventional cardiology and electrophysiology procedures have proven to be very effective at treating arrhythmias and coronary artery disease at sitesaccessible through the vasculature without the patient trauma, complications, recovery times and cost generally associated with open-heart surgery. With theadvent of advanced imaging techniques and sophisticated catheter and wire-based devices and techniques, the number of potential patients who can benefitfrom non-surgical interventional procedures has grown. However, we believe major challenges associated with manual approaches to electrophysiology andinterventional cardiology persist. In electrophysiology, challenges include precisely navigating the tip of the mapping and ablation catheter to the treatment siteon the heart wall and maintaining tissue contact throughout the cardiac cycle to effect treatment, and, for atrial fibrillation, performing complex ablationswithin the left atrium of the heart. A major limitation is the manual dexterity required to perform complex ablations. As a result, large numbers of patients arereferred to palliative drug therapy that can have harmful side effects. In interventional cardiology, these challenges include difficulty in navigating thedisposable interventional device through tortuous vasculature and crossing certain types of complex lesions to deliver balloons or stents to effect treatment. As aresult, numerous patients who could be candidates for an interventional approach continue to be referred to bypass surgery.We believe the Epoch Solution represents a revolutionary step compared to manual techniques in the trend toward highly effective, but less invasive,cardiac procedures. As the first technology to permit direct, computerized control of the working tip of a disposable interventional device, the Niobe systemenables physicians to perform cardiac procedures interventionally that historically would have been very difficult or impossible to perform in this way andhas the potential to significantly improve both the efficiency and efficacy of these treatments. We believe that the Odyssey Solution will provide physicians theability to enhance procedure workflow, more effectively manage their interventional procedures, and collaborate with other physicians. We believe the Vdrivesystem will provide physicians with the ability to navigate and control diagnostic catheters and sheaths from either the procedure room or the nearby controlroom, which will facilitate the performance of procedures remotely while further improving efficiency and efficacy of the procedure.CURRENT CHALLENGES IN INTERVENTIONAL MEDICINEAlthough great strides have been made in manual device technology and in related manual interventional techniques, significant challenges remain thatreduce interventional productivity and limit both the number of complex procedures and the types of diseases that can be treated manually. These challengesprimarily involve the inherent mechanical limitations of manual instrument control and the lack of integration of the information systems used by physiciansin the interventional lab as well as a significant amount of training and experience required to ensure proficiency. As a result, many complex cases inelectrophysiology are treated with palliative drug therapy, and many complex procedures in interventional cardiology are still referred to highly invasive bypasssurgery.Limitations of Instrument ControlManually controlled catheters, guidewires and other delivery devices, even in the hands of the most skilled specialist, have inherent instrument controllimitations. In traditional interventional procedures, the device is manually manipulated by the physician who twists and pushes the external end of theinstrument in an iterative process to thread the instrument through often tortuous blood vessels or into the chambers of the heart to the treatment site.Lack of Integration of Information SystemsWhile sophisticated imaging, mapping and location-sensing systems have provided visualization for interventional procedures and allowedinterventional physicians to treat more complex conditions, the substantial lack of integration of these information systems requires the physician to mentallyintegrate and process large quantities of information from different sources in real time during an interventional procedure. For example, a physician ablatingheart tissue to eliminate an arrhythmia will often be required to mentally integrate information from a number of sources, including: • real-time x-ray fluoroscopy and/or ultrasound images; • a real-time location-sensing system providing the 3D location of the catheter tip; 4 • a pre-operative map of the electrical activity or anatomy of the patient’s heart; • real-time recording of electrical activity of the heart; and • temperature feedback from an ablation catheter.Each of these systems displays data differently, requiring physicians to continuously reorient themselves to the different formats and displays as theyshift their focus from one data source to the next while at the same time manually controlling the interventional instrument. Also, each of these informationsystems can require a separate user interface, which further reduces the efficiency of the procedure.THE STEREOTAXIS VALUE PROPOSITIONThe Epoch Solution addresses the current challenges in the interventional lab by providing precise computerized control of the working tip of theinterventional instrument and by integrating this control with the visualization technology and information systems used during interventional cardiology andelectrophysiology procedures, on a cost-justified basis.We believe that our systems will: • Expand the market by enhancing the treatment of more complex cases. Treatment of a number of major diseases, including atrial fibrillation,ventricular tachycardia, cardiac chronic total occlusions, and critical limb ischemia due to chronic total occlusions of peripheral arteries, ishighly problematic using conventional wire and/or catheter-based techniques. Additionally, many patients with multi-vessel disease and certaincomplex arrhythmias, such as atrial fibrillation and ventricular tachycardia, are often referred to other more invasive or less curative therapiesbecause of the difficulty in precisely and safely controlling the working tip of disposable interventional devices used to treat these complex casesinterventionally. Because our robotic technology provides precise, computerized control of the working tip of disposable interventional devices, webelieve that it will potentially enable difficult atrial fibrillation, ventricular tachycardia and cardiac chronic total occlusions to be treatedinterventionally on a much broader scale than today. • Improve outcomes by optimizing therapy. Difficulty in controlling the working tip of disposable interventional devices can lead to sub-optimalresults in many procedures. Conversely, the precise control of multiple complex diagnostic and therapeutic devices by a single physician can leadto better outcomes for the patient. Precise instrument control is necessary for treating a number of cardiac conditions. To treat arrhythmias, preciseplacement of an ablation catheter against a beating inner heart wall is necessary. For coronary artery disease, precise and correct navigation andplacement of expensive stents also have a significant impact on procedure costs and outcomes. We believe our robotic technology can enhanceprocedure results by improving navigation of disposable interventional devices to treatment sites, and by effecting more precise, safe, treatmentsonce these sites are reached. • Enhance patient and physician safety. The Niobe system has been used in more than 66,000 procedures and the incidence of all reported majoradverse cardiac events associated with the use of the system for all procedures is approximately 0.3%. This represents what we believe to be aclinically significant improvement in major complication rates over conventional procedures, which can range as high as 2-6% for complexablations, and significantly higher for new physicians and fellows. Additionally, during conventional catheter-based procedures, each of thephysicians who stand by the patient table to manually control the catheter, the nursing staff assisting with the procedure, and the patient areexposed to the potentially harmful x-ray radiation from the fluoroscopy field. This exposure can be minimized by reducing procedure times.Reducing procedure times is also beneficial to the patient because of the direct correlation between complication rates and procedure length. Ourrobotic technology can further improve physician safety and reduce physician fatigue by enabling them to conduct procedures remotely from anadjacent control room, which reduces their exposure to harmful radiation, and the orthopedic burden of wearing lead. 5 • Improve clinical workflow and information management. Complex ablation procedures involve several sources of information, whichconventionally require a physician to mentally integrate and process large quantities of information from different sources in real time, often fromseparate user interfaces. Sources of information include real time x-ray and/or ultrasound images, real time location sensing systems providing the3-D location of a catheter tip, pre-operative map of the electrical activity of the heart, real time recording of electrical activity of the heart, andtemperature feedback from an ablation catheter. The Odyssey Solution improves clinical workflow and information management efficiency byintegrating and synchronizing the multiple sources of diagnostic and imaging information found in the interventional labs into a large-screen userinterface with single mouse and keyboard control. • Enhance hospital efficiency by reducing and standardizing procedure times, disposables utilization and staffing needs. Conventionalinterventional procedure times currently range from several minutes to many hours as physicians often engage in repetitive, “trial and error”maneuvers due to difficulties with manually controlling the working tip of disposable interventional devices. By reducing both navigation timeand the time needed to carry out therapy at the target site, we believe that our robotic technology can reduce complex procedure times compared tomanual procedures. We believe the Niobe system can also reduce the variability in procedure times compared to manual methods. Greaterstandardization of procedure times allows for more efficient scheduling of interventional cases including staff requirements. We also believe thatadditional cost savings from robotics result from decreased use of multiple catheters, guidewires and contrast media in procedures compared withmanual methods further enhancing the rate of return to hospitals. • Improve physician skill levels in order to improve the efficacy of complex cardiology procedures. Training required for physicians to safelyand effectively carry out manual interventional procedures typically takes years, over and above the training required to become a specialist incardiology. This has led to a shortage of physicians who are skilled in performing more complex procedures. We believe that our robotictechnology can allow procedures that previously required the highest levels of manual dexterity and skill to be performed effectively by a broaderrange of interventional physicians, with more standardized outcomes. In addition, interventional physicians can learn to use robotic systems in arelatively short period of time. The Niobe system can also be programmed to carry out sequences of complex navigation automatically furtherenhancing ease of use. We believe the Odyssey Solution can allow advanced training online thereby accelerating learning. • Help hospitals recruit physicians and attract patients. Due to the clinical benefits of the Epoch Solution, we believe hospitals will realizesignificant operational benefits when recruiting physicians to work in a more safe procedure environment, while attracting patients who desire tohave safer procedures that lead to better long term outcomes.OUR PRODUCTSNiobe ES Robotic Magnetic Navigation SystemOur proprietary Niobe ES system is the latest generation of the Niobe system, which provides the physician with precise remote digital instrumentcontrol through user friendly “point and click” computer mouse control, in combination with sophisticated image integration and 3D reconstruction. It can beoperated either from beside the patient table, as in traditional interventional procedures, or from an adjacent room and outside the x-ray fluoroscopy field. TheNiobe system allows the operator to navigate disposable interventional devices to the treatment site through complex paths in the blood vessels and chambers ofthe heart to deliver treatment by using computer controlled, externally applied magnetic fields to directly govern the motion of the working tip of these devices,each of which has a magnetically sensitive tip that predictably responds to magnetic fields generated by our system. Because the working tip of the disposableinterventional device is directly controlled by these external magnetic fields, the physician has the same degree of control regardless of the number or type ofturns, or the distance traveled by the working tip to arrive at its position in the blood vessels or chambers of the heart. This results in highly precise digitalcontrol of the working tip of the disposable interventional device while still giving the physician the option to manually advance the device. 6®Through our alliances with Siemens, Philips and Biosense Webster, this precise digital instrument control has been integrated with the visualization andinformation systems used during electrophysiology procedures in order to provide the physician with a fully-integrated and automated information andinstrument control system. We have integrated our Niobe system with Siemens’ and with Philips’ digital x-ray fluoroscopy systems. In addition, we haveintegrated the Niobe system with Biosense Webster’s 3D catheter location sensing technology to provide accurate real-time information as to the 3D location ofthe working tip of the instrument, and with Biosense Webster’s ablation tip technology. The combination of these technologies was fully launched in 2005.The components of the Niobe system are identified and described below:Niobe Robotic Magnetic Navigation System. Our Niobe system utilizes two permanent magnets mounted on articulating and pivoting arms that areenclosed within a stationary housing, with one magnet on either side of the patient table. These magnets generate magnetic navigation fields that are less than10% of the strength of fields typically generated by MRI equipment and therefore require significantly less shielding, and cause significantly less interference,than MRI equipment. The Niobe system is indicated for use in cardiac, peripheral and neurovascular applications.Cardiodrive Automated Catheter Advancement System. As the physician conducts the procedure from the adjacent control room, the CardiodriveAutomated Catheter Advancement System (“Cardiodrive”) or QuikCAS automated catheter advancement systems are used to remotely advance and retractthe electrophysiology catheter in the patient’s heart while the Niobe magnets precisely steer the working tip of the device.Odyssey SolutionThe Odyssey Solution offers a fully integrated, real-time information solution to manage, control, record and share procedures across networks oraround the world. We believe that the Odyssey Solution enhances the physician workflow in interventional labs through a consolidated user interface ofmultiple systems on a single display to enable greater focus on the case and improve the efficiency of the lab. Through the use of a single mouse andkeyboard, the Odyssey Solution allows the user to command multiple systems in the lab from a single point of control. In addition, the Odyssey Solutionacquires a real-time, remote view of the lab capturing synchronized procedure data for review of important events during cases. The Odyssey Solution enablesphysicians to access recorded cases and create snapshots following procedures for enhanced clinical reporting, auditing and presentation. The OdysseySolution enables physicians to establish a comprehensive master archive of procedures performed in the lab providing an excellent tool for training new staffon the standard practices. The Odyssey Solution further enables procedures to be observed remotely around the world with high speed Internet access over ahospital VPN even wirelessly using a standard laptop or Windows tablet computer.Vdrive™ Robotic Navigation SystemThe Vdrive system reaches further into the evolution of electrophysiology robotic navigation technologies than any platform before it. More than a roboticcatheter manipulator, the Vdrive system and Niobe ES robotic system provide independent remote manipulation of diagnostic catheters and magnetic ablationcatheters in a single interface. The Vdrive system provides breakthrough navigation and stability for diagnostic and ablation devices designed with keyfeatures to assist in the delivery of better ablations. Important features include complementing the Niobe ES control of catheters with fully remote, singleoperator workflow; and providing robotic control of diagnostic devices independent of magnetic navigation. The Vdrive Duo system is an optional expansionof the Vdrive hardware that allows control of any two of the four available disposable options (V-Loop, V-Sono, V-CAS, and V-CAS Deflect).Disposables and Other AccessoriesOur Niobe system is designed to use a toolkit of proprietary disposable interventional devices. The toolkit currently consists of: • our QuikCAS automated catheter advancement disposables designed to provide precise remote advancement of proprietary electrophysiologycatheters; 7®®® • Biosense Webster’s CARTO RMT navigation and ablation system, CELSIUS RMT, NAVISTAR RMT, NAVISTAR RMT DS,NAVISTAR RMT THERMOCOOL and CELSIUS RMT THERMOCOOL Irrigated Tip Diagnostic/Ablation Steerable Tip Catheters co-developed by Biosense Webster and Stereotaxis, as described below; and • Our suite of Titan and Pegasus coronary guidewires designed for use in interventional cardiology procedures for the introduction and placementof over-the-wire therapeutic devices, such as stents and angioplasty balloons.We believe that we can adapt many of the applicable disposable interventional devices for use with our system by using our proprietary technology toadd an inexpensive micro-magnet at their working tip. This micro-magnet is activated by an external magnetic field, which allows interventional devices withtip dimensions as small as 14 thousandths (0.014) of an inch to be oriented and positioned in a predictable and controllable fashion. We believe this approachto bringing digital control to disposable interventional devices using embedded magnets can simplify the overall design of these devices because mechanicalcontrols are no longer required.In addition to the Vdrive and Vdrive Duo systems, we also manufacture and market various disposable components which can be manipulated bythese systems. These include: • our V-CAS catheter advancement system (“V-CAS system”) that controls both the magnetic catheter body and a standard fixed-curve sheath; • our V-CAS Deflect fully integrated catheter advancement system (“V-CAS Deflect system”) with a robotic deflectable sheath for maximumintegration and versatility, allowing users to advance and retract the magnetic catheter body at angles up to 270°; • our V-Loop circular catheter manipulator (“V-Loop device”), which allows the user to control certain circular mapping catheters, such asBiosense Webster’s LASSO2515 or LASSO2515 NAV Circular Mapping Catheter, advance, retract, rotate, deflect and adjust loop radius,and hold the catheter position against the tissue to optimize electrograms; and • our V-Sono ICE catheter manipulator (“V-Sono device”) that allows a single physician to manipulate BWI SoundStar™ and AcuNav™ cathetersand CARTO 3™ System from the control room, store and recall previous positions and automatically sweep over an area of interest withadjustable speed and angle—all without leaving the control room.Regulatory ApprovalWe began commercial shipments of our Niobe system in 2003, following U.S. and European regulatory clearance of its core components. We havereceived regulatory clearance, licensing and/or CE Mark approvals necessary for us to market the Niobe system, the Cardiodrive, and various disposableinterventional devices in the U.S., Canada, Europe, China, Japan, and various other countries.We have received regulatory clearance, licensing and/or CE Mark approvals necessary for us to market the Odyssey Solution in the U.S., Canada,European Union, China and some other countries and we are in the process of obtaining necessary approvals for extending our markets in other countries.We have received the CE Mark that allows us to market the Vdrive and Vdrive Duo systems with the V-CAS, V-CAS Deflect, V-Loop and V-Sonodevices in Europe. In addition, we have received licensing to market the Vdrive and Vdrive Duo systems with the V-CAS, V-CAS Deflect, and V-Loop devicesin Canada and have applied for a license of the V-Sono device. We have received regulatory clearance that allows us to market the Vdrive with V-Sono devicein the United States. We are in the process of obtaining the necessary clearance for the V-Loop device in the United States.We have received Food and Drug Administration (“FDA”) clearance and the CE Mark necessary for us to market our suite of Titan and Pegasuscoronary peripheral guidewires in the U.S. and Europe. 8®®®®®®®®®®Biosense Webster has received FDA approval, Chinese CFDA approval, and CE Mark for the CARTO RMT navigation system for use with theNiobe system, the 4mm CELSIUS RMT Diagnostic/Ablation Steerable Tip Catheter, the 4mm NAVISTAR RMT Diagnostic/Ablation Steerable TipCatheter, the 8mm Navistar RMT DS Diagnostic/Ablation Steerable Tip Catheter, and the 3.5mm NAVISTAR RMT THERMOCOOL Irrigated TipCatheter. In addition, Biosense Webster has received FDA approval and CE Mark for the 3.5mm CELSIUS RMT THERMOCOOL Irrigated Tip Catheter.Our alliance with Biosense Webster provides for co-development of catheters that can be navigated with our system, both with and without Biosense Webster’s3D catheter location sensing technology. In addition, we can utilize technology which allows our system to recognize specific disposable interventional devicesin order to prevent unauthorized use of our system. See “Strategic Alliances—Disposable Devices Alliance” below for a description of our arrangements withBiosense Webster.FINANCIAL INFORMATION ABOUT GEOGRAPHIC AREASOur total U.S. revenue was $24.0 million, $27.0 million, and $23.9 million for the years ended December 31, 2013, 2012, and 2011, respectively. Ourtotal international revenue was $14.0 million, $19.5 million and $18.0 million for the years ended December 31, 2013, 2012, and 2011, respectively.CLINICAL APPLICATIONSWe have focused our clinical and commercial efforts on applications of the Epoch Solution primarily in electrophysiology procedures for the treatmentof arrhythmias and secondarily in complex interventional cardiology procedures for the treatment of coronary artery disease. Our system potentially has broadapplicability in other areas, such as structural heart repair, interventional neurosurgery, interventional neuroradiology, peripheral vascular, renal denervation,pulmonology, urology, gynecology and gastrointestinal medicine, and our patent portfolio has been structured to permit expansion into these areas.ElectrophysiologyThe rhythmic beating of the heart results from the transmission of electrical impulses. When these electrical impulses are mistimed or uncoordinated, theheart fails to function properly, resulting in symptoms that can range from fatigue to stroke or death. Over 4.3 million people in the U.S. currently suffer fromthe resulting abnormal heart rhythms, which are known as arrhythmias. The most common arrhythmia in adults is atrial fibrillation. This chaotic electricalactivity of the top chambers of the heart is estimated to be present in three million people in the United States and over seven million people worldwide. Theincidence is expected to continue to rise as the population ages and life expectancy continues to increase. Atrial fibrillation is a major physical and economicburden. This arrhythmia is associated with stroke, heart failure, and adverse symptoms causing patients to be very motivated to seek treatment. Thecombination of symptoms, prevalence and co-morbidities make atrial fibrillation a major economic factor in healthcare. We believe payors are very interestedin therapies that may reduce the financial impact of this disease.Drug therapies for arrhythmias often fail to adequately control the arrhythmia and may have significant side effects. Consequently, physicians haveincreasingly sought more permanent, non-pharmacological, solutions for arrhythmias. The most common interventional treatment for arrhythmias, and inparticular tachyarrhythmias, where the patient’s heart rate is too high or irregular, is an ablation procedure in which the diseased tissue giving rise to thearrhythmia is isolated or destroyed. Prior to performing an electrophysiology ablation, a physician typically performs a diagnostic procedure in which theelectrical signal patterns of the heart wall are “mapped” to identify the heart tissue generating the aberrant electrical signals. Following the mapping procedure,the physician may then use an ablation catheter to eliminate the aberrant signal or signal path, restoring the heart to its normal rhythm. In cases where anablation is anticipated, physicians will choose an ablation catheter and perform both the mapping and ablation with the same catheter. In February 2009 theFDA approved the Biosense Webster NAVISTAR THERMOCOOL irrigated catheter to be labeled for the treatment of atrial fibrillation. This is the firstdevice approved by the FDA to be labeled for the interventional treatment of this arrhythmia. We believe this important milestone will accelerate acceptance ofablations for the treatment of atrial fibrillation. 9®®®®®®®®®We believe more than 3,000 interventional labs around the world are currently capable of conducting electrophysiology procedures. Approximately600,000 electrophysiology procedures are performed annually worldwide, and procedure growth rate is 10% annually.We believe the Epoch Solution is particularly well-suited for those electrophysiology procedures which are time consuming or which can only beperformed by highly experienced physicians. These procedures include: • General Mapping and Ablations. For the more routine mapping and ablation procedures, our system offers the unique benefit of precise cathetermovement and consistent heart wall contact. Additionally, the system can control the procedure and direct catheter movement from the controlroom, saving the physician time and helping to avoid unnecessary exposure to high doses of radiation. • Atrial Fibrillation. The most commonly diagnosed abnormal heart rhythm, atrial fibrillation, is a particular type of arrhythmia characterized byrapid, disorganized contractions of the heart’s upper chambers, the atria, which lead to ineffective heart pumping and blood flow and can be amajor risk factor for stroke. The number of potential patients for manual catheter-based procedures for atrial fibrillation has been limited becausethe procedures are extremely complex and are performed by only the most highly skilled electrophysiologists. They also typically have muchlonger procedure times than general ablation cases and the success rates have been lower and more variable. We believe that our system can allowthese procedures to be performed by a broader range of electrophysiologists and, by automating some of the more complex catheter maneuvers, canstandardize and reduce procedure times and significantly improve outcomes. • Ventricular Tachycardia. Ventricular tachycardia is a malignant, potentially lethal arrhythmia that is extremely difficult and time consuming totreat. The magnetic catheter has been characterized as the ideal tool for this application. These arrhythmias can often be modified or interrupted bythe pressure of a conventional catheter making it very difficult to identify the appropriate location for the ablation, whereas magnetic cathetersproduce fewer extra beats and provide for easier and more efficient mapping of the diseased tissue. Successful ablation of ventricular tachycardiacan extend the useful life of an implantable defibrillator, reduce shocks to the patient, reduce the need for antiarrhythmic drugs or, in some cases,obviate the need for an expensive implantable device and its associated follow-up.We believe that our system can address the current challenges in electrophysiology by permitting the physician to remotely navigate disposableinterventional devices from a control room outside the x-ray field. Additionally, we believe that our system allows for more predictable and efficient navigationof these devices to the treatment site, including the left atrium for atrial fibrillation procedures, and enables catheter contact to be consistently maintained toefficiently apply energy on the wall of the beating heart. We also believe that our system will significantly lower the skill barriers required for physicians toperform complex electrophysiology procedures and, additionally, improve interventional lab efficiency and reduce disposable interventional device utilization.Interventional CardiologyMore than half a million people die annually from coronary artery disease, a condition in which the formation of plaque in the coronary arteriesobstructs the supply of blood to the heart, making this the leading cause of death in the U.S. Despite various attempts to reduce risk factors, each year overone million patients undergo interventional procedures in an attempt to open blocked vessels and another one half million patients undergo open heart surgeryto bypass blocked coronary arteries.Blockages within a coronary artery, often called lesions, are categorized by degree of obstruction as partial occlusions, non-chronic total occlusions andchronic total occlusions. Lesions are also categorized by the degree of difficulty with which they can be opened as simple or complex. Complex lesions, suchas chronic total occlusions, longer lesions, and lesions located within smaller diameter vessels, are often very difficult or time consuming to open with manualinterventional techniques. 10We believe well over 10,000 interventional labs worldwide are currently capable of conducting interventional cardiology. Approximately 4 millioninterventional cardiology procedures are performed annually in the U.S. alone. We estimate that approximately 10-15% of these interventional cardiologyprocedures currently being performed are complex and therefore require longer procedure times and may have sub-optimal outcomes. We believe that oursystem can substantially benefit this subset of complex interventional cardiology procedures.Interventional Neuroradiology, Neurosurgery and Other Interventional ApplicationsPhysicians used a predecessor to our Niobe system to conduct a number of procedures for the treatment of brain aneurysms, a condition in which aportion of a blood vessel wall balloons and which can result in debilitating or fatal bleeding and strokes. The Niobe system also has a range of potentialapplications in minimally invasive neurosurgery, including biopsies and the treatment of tumors, treatment of vascular malformations and fetal interventions.STRATEGIC ALLIANCESWe have entered into strategic alliances with technology leaders in the global interventional market, including Siemens, Philips, and Biosense Webster,that we believe aid us in commercializing our Niobe system. We believe our two imaging partners, Siemens and Philips, have a significant percentage of theinstalled base of imaging systems worldwide.We believe that these strategic alliance arrangements are favorable to Stereotaxis because they: • provide for the integration of our system with market leading digital imaging and 3D catheter location sensing technology, as well as disposableinterventional devices; • allow us to leverage the sales, distribution, service and maintenance expertise of our strategic alliances; and • enable operational flexibility by not requiring us to provide any of the parties in our strategic alliances with a right of first refusal in the event thatanother party wants to acquire us or with board representation where a strategic alliance has made a debt or equity investment in us.Imaging AlliancesSiemens and Philips Alliances. We have successfully integrated our Niobe system with both Siemens’ and Philips’ digital fluoroscopy systems toprovide advanced interventional lab visualization and instrument control through user-friendly computerized interfaces. We also coordinate our sales effortswith Siemens and Philips to co-market integrated systems at leading hospital sites in the U.S., Europe and in Asia. We have also entered into a softwaredistribution agreement with Siemens under which we have the right to sublicense Siemens’ 3D pre-operative image navigation software as part of our advanceduser interface for the Niobe ES system.Disposables Devices AllianceBiosense Webster Alliance. We entered into an alliance in May 2002 pursuant to which we agreed to integrate Biosense Webster’s advanced 3D catheterlocation sensing technology, which we believe has the leading market position in this important field of visualization for electrophysiology procedures, withour instrument control system, and to jointly develop associated location sensing electrophysiology mapping and ablation catheters that are navigable with theNiobe system. We believe that these integrated products will provide physicians with the elements required for effective complex electrophysiology procedures:highly accurate information as to the exact location of the catheter in the body and highly precise control over the working tip of the catheter. We also agreed tocoordinate our sales force efforts with Biosense Webster in order to place Biosense CARTO RMT systems and our Niobe systems that, together with the co-developed catheters, comprise the full integration of our instrument control and 3D location sensing technologies in the interventional lab. We expanded thisalliance in November 2003 to include the parallel integration of our instrument control 11®technology with Biosense Webster’s full line of non-location sensing mapping and ablation catheters that are relevant to our targeted applications inelectrophysiology. Under an amendment to this agreement in 2008, Biosense Webster advanced us $10 million and allowed us to defer up to $8 million ofpayments due to Biosense Webster for research and development related to jointly developed products. These amounts plus interest accrued thereon had beenrepaid as of December 31, 2011.The co-developed catheters are manufactured and distributed by Biosense Webster, and both of the parties agreed to contribute to the resources requiredfor their development. We are entitled to royalty payments from Biosense Webster, payable quarterly based on net revenues from sales of the co-developedcatheters. These royalties are used to make payments under the debt agreement with Healthcare Royalty Partners II, L.P. (formerly “Cowen Healthcare RoyaltyPartners II, L.P.”) as discussed in Item 7. Under the alliance with Biosense Webster, we agreed to certain restrictions on our ability to co-develop and distributecatheters competitive with those we are developing with Biosense Webster and we granted Biosense Webster certain notice and discussion rights for productdevelopment activities we undertake relating to localization of magnetically enabled interventional disposable devices in fields outside of electrophysiology andmapping.Either party may terminate this alliance in certain specified “change of control” situations, although the termination would not be effective until one yearafter the change of control and then would be subject to a wind-down period during which Biosense Webster would continue to supply co-developed cathetersto us or to our customers for three years (or, for non-location sensing mapping and ablation catheters, until our first sale of a competitive product after achange of control, if earlier than three years). If either party terminates the agreement under this provision, we must pay a termination fee to Biosense Websterequal to 5% of our total equity value in the change of control transaction, up to a maximum of $10 million. If a change of control of Stereotaxis occurs afterBiosense Webster has received approval from the U.S. FDA for atrial fibrillation indication for the NAVISTAR RMT THERMOCOOL catheter, we wouldbe required to pay an additional $10 million fee to Biosense Webster, and termination of the agreement by either party would not be effective until two yearsafter the change of control. We also agreed to notify Biosense Webster if we reasonably believe that we are engaged in substantive discussions with respect tothe sale of the Company or substantially all of our assets.In January 2011, we executed an amendment, effective December 2010, to our agreement with Biosense Webster to extend the development anddistribution alliance related to certain catheters that have been developed under previous collaboration activities between Biosense Webster and us on anexclusive basis until December 31, 2015 and thereafter on a nonexclusive basis until December 31, 2018. Biosense Webster’s rights to distribute suchproducts in Japan is extended on an exclusive basis to the later of December 31, 2017 or five years after the date of approval of the applicable product for salein Japan and on a nonexclusive basis to the later of December 31, 2020 or eight years after the date of approval of the applicable product for sale in Japan. Thecatheter most recently developed under the collaboration activities with Biosense Webster was approved for sale in Japan on March 22, 2013. Additionally,both companies agreed to expand the product offering covered by the agreement to include a next generation irrigated magnetic catheter, which will integratetechnological advancements from both companies.In May 2011, we entered into a new agreement, under which we granted Biosense Webster global, non-exclusive rights to resell Stereotaxis’ Odysseyproducts, including Odyssey Vision and Odyssey Cinema systems.RESEARCH AND DEVELOPMENTWe have assembled an experienced group of engineers and physicists with recognized expertise in magnetics, software, control algorithms, systemsintegration and disposable interventional device modeling and design.Our research and development efforts are focused in the following areas: • continuing to enhance our existing Niobe system, Odyssey Solution, and Vdrive system through ongoing product and software development; and • designing new proprietary disposable interventional devices for use with our system. 12®®Our research and development team collaborates with our strategic partners, Siemens, Philips, and Biosense Webster, to integrate our Niobe system’sopen architecture platform with key imaging, location sensing and information systems in the interventional lab. We have also collaborated with a number ofhighly regarded interventional physicians in key clinical areas and have entered into agreements with a number of universities and teaching hospitals, whichserve to increase our access to world class physicians and to expand our name recognition in the medical community. Our research and development expensesfor the years ending December 31, 2013, 2012, and 2011, were $5.7 million, $8.4 million, and $12.9 million, respectively.CUSTOMER SERVICE AND SUPPORTWe provide worldwide maintenance and support services to our customers for our integrated products with the assistance of certain strategically-basedrepresentatives. By utilizing these relationships, we provide direct, on-site technical support activities, including call center, customer support engineers andservice parts logistics and delivery. In certain situations, we use these third parties as a single point of contact for the customer, which allows us to focus onproviding installation, training, and back-up technical support.Our back-up technical support includes a combination of on-line, telephone and on-site technical assistance services 24 hours a day, seven days a week.We have also hired service and support engineers with networking and medical equipment expertise, and have outsourced a portion of our installation andsupport services. We offer different levels of support to our customers, including basic hardware and software maintenance, extended product maintenance,and rapid response capability for both parts and service.We have established a call center in our St. Louis facilities, which provides real-time clinical and technical support to our customers worldwide.MANUFACTURINGNiobe, Odyssey, and Vdrive SystemsOur manufacturing strategy for our Niobe system, Vdrive system and Odyssey Solution is to sub-contract the manufacture of major subassemblies ofour system to maximize manufacturing flexibility and lower fixed costs. Our current manufacturing strategy for Vdrive system is to build all subassembliesin-house. We maintain quality control for all of our systems by completing final system assembly and inspection in-house.Disposable Interventional DevicesOur manufacturing strategy for disposable interventional devices is to outsource their manufacture through subcontracting and through our alliance withBiosense Webster and to expand partnerships for other interventional devices. We work closely with our contract manufacturers and have strong relationshipswith component suppliers. We have entered into manufacturing agreements to provide high volume capability for devices other than catheters.SoftwareThe software components of the Niobe system, the Vdrive system and Odyssey Solution, including control and application software, are developedboth internally and with integrated modules we purchase or license. We perform final testing of software products in-house prior to their commercial release.GeneralOur manufacturing facilities operate under processes that meet the FDA’s requirements under the Quality System Regulation, or QSR. 2011 FDAEstablishment Inspections of our Maple Grove, Minnesota facility noted no observations. Our ISO registrar and European notified body has audited ourfacilities annually since 2001 and found the facilities to be in compliance with requirements. The initial ISO 9001 certification was issued in January 2002and the most recent ISO 13485 certificate was issued in 2013. 13SALES AND MARKETINGWe market our products in the U.S and internationally through a direct sales force of senior sales specialists, distributors and sales agents, supportedby account managers and clinical specialists who provide training, clinical support, and other services to our customers. In addition, our strategic alliancesform an important part of our sales and marketing strategy. We leverage the sales forces of our imaging partners to co-market integrated systems on aworldwide basis. This approach allows us to maximize our leads and knowledge of the market opportunities while using our resources to sell directly to thecustomer. Under the terms of our agreement, Biosense Webster exclusively distributes magnetically enabled electrophysiology mapping and ablation catheters,co-developed pursuant to our alliance with them.Our sales and marketing efforts include two important elements: (1) selling Niobe system, Odyssey Solution, and Vdrive system directly and throughdistributors; and (2) leveraging our installed base of systems to drive recurring sales of disposable interventional devices, software and service.REIMBURSEMENTWe believe that substantially all of the procedures, whether commercial or in clinical trials, conducted in the U.S. with the Niobe system or Vdrivesystem have been reimbursed to date. We expect that third-party payors will reimburse, under existing billing codes, procedures in which our line of ablationcatheters and those on which we are collaborating with Biosense Webster, as well as our line of guidewires, are used. We expect healthcare facilities in the U.S.to bill various third-party payors, such as Medicare, Medicaid, other government programs and private insurers, for services performed with our products.We believe that procedures performed using our products, or targeted for use by products that do not yet have regulatory clearance or approval, are generallyalready reimbursable under government programs and most private plans. Accordingly, we believe providers in the U.S. will generally not be required toobtain new billing authorizations or codes in order to be compensated for performing medically necessary procedures using our products on insured patients.We cannot guarantee that reimbursement policies of third-party payors will not change in the future with respect to some or all of the procedures using theNiobe system.In countries outside the United States, reimbursement is obtained from various sources, including governmental authorities, private health insuranceplans, and labor unions. In most foreign countries, private insurance systems may also offer payments for some therapies. Additionally, health maintenanceorganizations are emerging in certain European countries. In the European Union, we believe that substantially all of the procedures, whether commercial or inclinical trials, conducted with the Niobe system or Vdrive system has been reimbursed to date. In Japan, the Ministry of Health, Labor and Welfare (MHLW)has classified the Niobe system as a C2 medical device (the highest reimbursement category) on an interim basis. The MHLW will establish a permanent“technical fee” for procedures using the Niobe system during its biennial review of insurance reimbursement pricing for C2 devices which is estimated tooccur around April 1, 2014. In other foreign countries, we may need to seek international reimbursement approvals, and we do not know if these requiredapprovals will be obtained in a timely manner or at all.See “Item 1A—Risk Factors” for a discussion of various risks associated with reimbursement from third-party payors.INTELLECTUAL PROPERTYOur strategy is to patent the technology, inventions and improvements that we consider important to the development of our business. As a result, wehave an extensive patent portfolio that we believe protects the fundamental scope of our technology, including our magnet technology, navigational methods,procedures, systems, disposable interventional devices and our 3D integration technology. As of December 31, 2013, we had 114 issued U.S. patents, 3 co-owned U.S. patents and 4 licensed-in U.S. patents. In addition, we had 22 pending U.S. patent applications and 2 co-owned U.S. patent applications. As ofDecember 31, 2013 we had 34 issued foreign patents and 19 owned Foreign Patent Applications. We also have a number of invention disclosures underconsideration and several applications that are being prepared for filing. 14The patent positions of medical device companies, including ours, can be highly uncertain and involve complex and evolving legal and factualquestions. One or more of the above patent applications may be denied. In addition, our issued patents may be challenged, based on prior art circumvented orotherwise not provide protection for the products we develop. Furthermore, we may not be able to obtain patent licenses from third parties required for thedevelopment of new products for use with our system. We also note that U.S. patents and patent applications may be subject to interference proceedings andU.S. patents may be subject to reexamination proceedings in the U.S. Patent and Trademark Office (and foreign patents may be subject to opposition orcomparable proceedings in the corresponding foreign patent office), which proceedings could result in either loss of the patent or denial of the patent applicationor loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such interference, reexamination and oppositionproceedings may be costly. In the event that we seek to enforce any of our owned or exclusively licensed patents against an infringing party, it is likely that theparty defending the claim will seek to invalidate the patents we assert, which, if successful could result in the entire loss of our patent or the relevant portion ofour patent and not just with respect to that particular infringer. Any litigation to enforce or defend our patents rights, even if we were to prevail, could be costlyand time-consuming and would divert the attention of our management and key personnel from our business operations.It would be technically difficult and costly to reverse engineer our Niobe system, which contains numerous complex algorithms that control ourdisposable devices inside the magnetic fields generated by the Niobe system. We further believe that our patent portfolio is broad enough in scope to enable usto obtain legal relief if any entity not licensed by us attempted to market disposable devices that can be navigated by the Niobe system. We can also utilizesecurity keys, such as embedded smart chips or associated software that could allow our system to recognize specific disposable interventional devices inorder to prevent unauthorized use of our system.We have also developed substantial expertise in magnet design, magnet physics and magnetic instrument control that was developed in connection withthe development of the Niobe system, which we maintain as trade secrets. This expertise centers around our proprietary magnet design, which is a criticalaspect of our ability to design, manufacture and install a cost-effective Magnetic Navigation System that is small enough to be installed in a standardinterventional lab. Our Odyssey Solution contains numerous complex algorithms and proprietary software and hardware configurations, and requiressubstantial knowledge to design and assemble, which we maintain as trade secrets. These proprietary software and hardware, some of which is owned byStereotaxis, and some of which is licensed to Stereotaxis, is a material aspect of the ability to design, manufacture and install a cost-effective and efficientinformation integration, storage, and delivery platform.We seek to protect our proprietary information by requiring our employees, consultants, contractors, outside parties and other advisers who are engagedin development work for us to execute nondisclosure and assignment of invention agreements upon commencement of their employment or engagement,through which we seek to protect our intellectual property. These agreements to protect our unpatented technology provide only limited and possibly inadequateprotection of our rights. Third parties may therefore be able to use our unpatented technology, reducing our ability to compete. In addition, employees,consultants and other parties to these agreements may breach them and adequate remedies may not be available to us for their breaches. Many of our employeeswere previously employed at universities or other medical device companies, including potential competitors. We could in the future be subject to claims thatthese employees or we have used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defendagainst these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights orpersonnel. Even if we are successful in defending against these claims, litigation could result in substantial costs and divert the attention of management andkey personnel from our business operations. We also generally seek confidentiality agreements from third parties that receive our confidential data or materials.Intellectual property risks and uncertainties are further discussed in “Item 1A—Risk Factors” in this annual report. 15COMPETITIONThe markets for medical devices are intensely competitive and are characterized by rapid technological advances, frequent new product introductions,evolving industry standards and price erosion.We consider the primary competition to our Niobe system to be existing manual catheter-based interventional techniques and surgical procedures. To ourknowledge, we are the only company that has commercialized remote, digital and direct control of the working tip of both catheters and guidewires forinterventional use. Our success depends in part on convincing hospitals and physicians to convert existing interventional procedures to computer-assistedprocedures.We also face competition from companies that are developing new approaches and products for use in interventional procedures, including roboticapproaches that are directly competitive with our technology. Some of these companies may have an established presence in the field of interventionalcardiology, including the major imaging, capital equipment and disposables companies that are currently selling products in the interventional lab. We areaware of one public company that has commercialized a catheter delivery system which has been cleared by the FDA for mapping procedures only. Inaddition, we are aware of one private company with an electro-magnetic catheter delivery system that has received CE Mark approval in Europe. We also facecompetition from companies who currently market or are developing non-radio frequency ablation therapy, drugs, gene or cellular therapies to treat theconditions for which our products are intended.We face direct competition to certain products in our Odyssey Solution, such as the Odyssey Vision system. These competitor products primarilycompete with individual components of our Odyssey Solution. We expect to continue to face competitive pressure in this market in the future, based on therapid pace of advancements with this technology.We believe that the primary competitive factors in the market we address are capability, safety, efficacy, ease of use, price, quality, reliability andeffective sales, support, training and service. The length of time required for products to be developed and to receive regulatory and reimbursement approval isalso an important competitive factor. See “Item 1A—Risk Factors” for a discussion of other competitive risks facing our business.GOVERNMENT REGULATIONThe healthcare industry, and thus our business, is subject to extensive federal, state, local and other national and international regulation. Some of thepertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Inaddition, these laws and their interpretations are subject to change.Both federal and state governmental agencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil andcriminal enforcement efforts. As indicated by work plans and reports issued by these agencies, the federal government will continue to scrutinize, among otherthings, the billing practices of healthcare providers and the marketing of healthcare products. The federal government also has increased funding in recentyears to fight healthcare fraud, and various agencies, such as the U.S. Department of Justice, the Office of Inspector General of the Department of Health andHuman Services, or OIG, and state Medicaid fraud control units, are coordinating their enforcement efforts.We believe that we have structured our business operations and relationships with our customers, consultants, agents, and distributors to comply withall applicable legal requirements. However, it is possible that governmental entities or other third parties could interpret these laws differently and assertotherwise. We discuss below the statutes and regulations that are most relevant to our business and most frequently cited in enforcement actions. 16U.S. Food and Drug Administration RegulationThe FDA strictly regulates the medical devices we produce under the authority of the Federal Food, Drug and Cosmetic Act (FD&C Act), and theregulations promulgated under the FD&C Act. The FD&C Act governs, among other things, the pre-clinical and clinical testing, design, manufacture, safety,efficacy, labeling, storage, record keeping, post market surveillance, reporting and advertising and promotion of medical devices.Our medical devices are categorized under the statutory framework described in the FD&C Act. This framework is a risk-based system whichclassifies medical devices into three classes from lowest risk (Class I) to highest risk (Class III). In general, Class I and II devices are either exempt from theneed for FDA clearance or cleared for marketing through a premarket notification, or 510(k), process. Our Class II devices subject to 510(k) requirementsprovide diagnostic information or are considered to be general tools, such as our Niobe system and our suite of guidewires, which have utility in a variety ofinterventional procedures. Our Class III therapeutic devices are subject to the premarket approval, or PMA, process. If clinical data are needed to supportclearance, approval or a marketing application for our devices, generally, an investigational device exemption, or IDE, is assembled and submitted to the FDA.The FDA reviews and must approve the IDE before the study can begin. In addition, the study must be approved by an Institutional Review Board coveringeach clinical site involved in the study. When all approvals are obtained, we initiate a clinical study to evaluate the device. Following completion of the study,we collect, analyze and present the data in an appropriate submission to the FDA (i.e. in support of either a 510(k) or PMA).Under the 510(k) process, the FDA determines whether or not the device is “substantially equivalent” to a previously marketed predicate device. Inmaking this determination, the FDA compares the new device to the predicate device and if the two devices are “substantially equivalent”, the device may becleared for marketing and introduction into domestic commerce. To establish substantial equivalence, the applicant must show that the new device has thesame intended use as the predicate device, and it either has the same technological characteristics or has been shown to be equally safe and effective and doesnot raise different questions of safety and effectiveness as compared to the predicate device.Under the PMA process, the FDA examines detailed data relating to the safety and effectiveness of the device. This information includes design,development, manufacture, labeling, advertising, pre-clinical testing, and clinical study data. Prior to approving the PMA, the FDA generally will conduct aninspection of the facilities producing the device and one or more clinical sites where the study was conducted. The establishment inspection evaluates theCompany’s readiness to commercially produce and distribute the device, including an evaluation of compliance under the Quality System Regulation (QSR).Under certain circumstances, the FDA may convene an advisory panel meeting to seek review of the data presented in the PMA. If the FDA’s evaluation isfavorable, the PMA is approved, and the device can be marketed in the U.S. The FDA may approve the PMA with conditions, such as post-marketsurveillance requirements.Further, we are subject to, at any time, periodic and routine inspection by the FDA to ensure compliance with the QSR requirements. Companies deemednon-compliant with the QSR in part or in full may receive a Warning Letter and/or be subject to other enforcement actions.We evaluate changes made to our products following 510(k) clearance or PMA approval for significance and if appropriate, make a subsequentsubmission to the FDA. In the case of a significant change being made to a 510(k) device, we submit a new 510(k). For a PMA device, we will either needapproval through a PMA supplement or will need to notify the FDA.For our 510(k) devices, we design the submission to cover multiple models or variations in order to minimize the number of submissions. For our PMAdevices, we often rely upon the PMA approvals of our strategic partners to utilize the PMA supplement regulatory path rather than pursue an original PMA.Because of the differences in the amount of data and numbers of patients in clinical trials, a PMA supplement process is often much simpler than thatrequired for approval of an original PMA. 17After a device is placed on the market, numerous regulatory requirements apply. These include: the QSR, labeling regulations, the FDA’s generalprohibition against promoting products for unapproved or “off-label” uses, the Medical Device Reporting regulation (which requires that manufacturers reportto the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to adeath or serious injury if it were to recur), and the Reports of Corrections and Removals regulation (which requires manufacturers to report recalls and fieldactions to the FDA if initiated to reduce a risk to health posed by the device or to remedy a violation of the FD&C Act). FDA enforces these requirements byinspection and market surveillance. If the FDA finds a violation, it can institute a wide variety of enforcement actions, ranging from a public warning letter tomore severe sanctions such as: • fines, injunctions, and civil penalties; • recall or seizure of products; • operating restrictions, partial suspension or total shutdown of production; • refusing requests for 510(k) clearance or PMA approval of new products; • withdrawing 510(k) clearance or PMA approvals already granted; and • criminal prosecution.International RegulationIn order for us to market our products in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulationsin other countries. These regulations, including the requirements for approvals or clearance and the time required for regulatory review, vary from country tocountry. Failure to obtain regulatory approval in a timely manner and to meet all local requirements including language and specific safety standards in anyforeign country in which we plan to market our products could prevent us from marketing products in such countries, limit our ability to generate revenue, orsubject us to sanctions and fines.The primary regulatory environment in Europe is that of the European Union, which consists of 28 countries encompassing most of the major countriesin Europe. The European Union requires that manufacturers of medical products obtain the right to affix the CE Mark to their products before selling them inmember countries of the European Union. The CE Mark is an international symbol of adherence to quality assurance standards and compliance withapplicable medical device directives. In order to obtain the right to affix the CE Mark to products, a manufacturer must obtain certification that its processesmeet certain quality standards. Compliance with the Medical Device Directive, as certified by a recognized European Notified Body, permits the manufacturerto affix the CE Mark on its products and commercially distribute those products throughout the European Union.If we modify existing products or develop new products in the future, including new devices, we will need to apply for permission to affix the CE Markto such products. We will be subject to regulatory audits, currently conducted annually, in order to maintain any CE Mark permissions we have alreadyobtained.To be sold in Japan, most medical devices must undergo thorough safety examinations and demonstrate medical efficacy before they receive regulatory(“Shonin”) approval. In March 2013, we received Shonin approval from the Japanese Ministry of Health, Labor, and Welfare (“MHLW”) for our NiobeSystem in Japan.Anti-Kickback StatuteThe federal healthcare program Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving or providingremuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or furnishing or arranging for a good or service, for whichpayment may be made under a federal healthcare program such as the Medicare and Medicaid programs. The definition of “remuneration” has been broadlyinterpreted to include anything of value, including for example gifts, discounts, 18the furnishing of supplies or equipment, credit arrangements, payments of cash and waivers of payments. Several courts have interpreted the statute’s intentrequirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statutehas been violated. Penalties for violations include criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from Medicare,Medicaid and other federal healthcare programs. Moreover, the intent element has been amended so that a person or entity no longer needs to have actualknowledge of the statute or specific intent to violate it.Many states have adopted laws similar to the federal Anti-Kickback Statute. Some of these state prohibitions apply to referral of patients for healthcareitems or services reimbursed by any source, not only the Medicare and Medicaid programs.Government officials have focused their enforcement efforts on marketing of healthcare services and products, among other activities, and recently havebrought cases against sales personnel who allegedly offered unlawful inducements to potential or existing customers in an attempt to procure their business. Aspart of our compliance program, we have established healthcare compliance policies and procedures and appointed a Clinical Compliance Officer to helpensure compliance with the Anti-Kickback Statute and similar state laws and we train our employees on our healthcare compliance policies.Beginning in 2013, under the Physician Payment Sunshine Act, we were required to track all “transfers of value” between Stereotaxis and USphysicians and/or teaching hospitals and other relevant healthcare professionals. The first report is due to the federal government in March 2014. Thisinformation will be published by the federal government on a searchable website in September 2014.HIPAA and Other Privacy LawsThe Health Insurance Portability and Accountability Act of 1996, or HIPAA, created two federal crimes: healthcare fraud and false statements relatingto healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, includingprivate payors.A violation of this statute is a felony and may result in fines, imprisonment or exclusion from government sponsored programs. The false statementsstatute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulentstatement in connection with the delivery of or payment for healthcare benefits, items or services. A violation of this statute is a felony and may result in finesor imprisonment.In addition to creating the two new federal healthcare crimes, HIPAA also establishes uniform standards governing the conduct of certain electronichealthcare transactions and protecting the security and privacy of individually identifiable health information maintained or transmitted by healthcareproviders, health plans and healthcare clearinghouses. Two standards have been promulgated under HIPAA: the Standards for Privacy of IndividuallyIdentifiable Health Information, which restrict the use and disclosure of certain individually identifiable health information, and the Standards for ElectronicTransactions, which establish standards for common healthcare transactions, such as claims information, plan eligibility, payment information and the useof electronic signatures. In addition, these security standards require covered entities to implement certain security measures to safeguard certain electronichealth information. In parallel with HIPAA, Stereotaxis is also subject to the Privacy and Security Standards as those Standards are applicable to it underHITECH, the Health Information Technology for Economic and Clinical Health Act, which is Title XIII of the American Recovery and Reinvestment Act.In addition to federal regulations issued under HIPAA, some states and foreign countries have enacted privacy and security statutes or regulations that,in some cases, are more stringent than those issued under HIPAA. In those cases, it may be necessary to modify our operations and procedures to comply withthe more 19stringent state and foreign laws, which may entail significant and costly changes for us. We believe that we are in compliance with such state and applicableforeign laws and regulations. However, if we fail to comply with applicable state or foreign laws and regulations, we could be subject to additional sanctions.Federal False Claims ActAnother trend affecting the healthcare industry is the increased use of the federal False Claims Act and, in particular, actions under the False ClaimsAct’s “whistleblower” or “qui tam” provisions. Those provisions allow a private individual to bring actions on behalf of the government alleging that thedefendant has defrauded the federal government. The government must decide whether to intervene in the lawsuit and to become the primary prosecutor. If itdeclines to do so, the individual may choose to pursue the case alone, although the government must be kept apprised of the progress of the lawsuit. Whetheror not the federal government intervenes in the case, it will receive the majority of any recovery. If the individual’s litigation is successful, the individual isentitled to no less than 15%, but no more than 30%, of whatever amount the government recovers. In recent years, the number of suits brought againsthealthcare providers by private individuals has increased dramatically. In addition, various states have enacted laws modeled after the federal False ClaimsAct.When an entity is determined to have violated the federal False Claims Act, it may be required to pay up to three times the actual damages sustained bythe government, plus civil penalties from $5,500 to $11,000 for each separate false claim. There are many potential bases for liability under the federal FalseClaims Act. Liability arises, primarily, when an entity knowingly submits, or causes another to submit, a false claim for reimbursement to the federalgovernment. Although simple negligence should not give rise to liability, submitting a claim with reckless disregard or deliberate ignorance of its truth or falsitycould result in substantial civil liability. The False Claims Act has been used to assert liability on the basis of inadequate care, improper referrals, andimproper use of Medicare numbers when detailing the provider of services, in addition to the more predictable allegations as to misrepresentations with respectto the services rendered. The False Claims Act has been amended such that a violation at the federal healthcare program Anti-Kickback Statute can serve as abasis for liability under the False Claims Act. We are unable to predict whether we could be subject to actions under the False Claims Act, or the impact ofsuch actions. However, the costs of defending claims under the False Claims Act, as well as sanctions imposed under the Act, could significantly affect ourfinancial performance.Certificate of Need LawsIn approximately two-thirds of the states, a certificate of need or similar regulatory approval is required prior to the acquisition of high-cost capital itemsor various types of advanced medical equipment, such as our Niobe system. At present, many of the states in which we sell Niobe systems have laws thatrequire institutions located in those states to obtain a certificate of need in connection with the purchase of our system, and some of our purchase orders areconditioned upon our customer’s receipt of necessary certificate of need approval. Certificate of need laws were enacted to contain rising health care costs,prevent the unnecessary duplication of health resources, and increase patient access for health services. In practice, certificate of need laws have preventedhospitals and other providers who have been unable to obtain a certificate of need from acquiring new equipment or offering new services. A further increase inthe number of states regulating our business through certificate of need or similar programs could adversely affect us. Moreover, some states may haveadditional requirements. For example, we understand that California’s certificate of need law also incorporates seismic safety requirements which must be metbefore a hospital can acquire our Niobe system.EmployeesAs of December 31, 2013, we had 123 employees, 22 of whom were engaged directly in research and development, 48 in sales and marketing activities,22 in manufacturing and service, 5 in regulatory, clinical affairs and quality activities, 6 in training activities and 20 in general administrative andaccounting activities. A significant majority of our employees is not covered by a collective bargaining agreement, and we consider our relationship with ouremployees to be good. 20Availability of InformationWe make certain filings with the SEC, including our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, andall amendments and exhibits to those reports, available free of charge in the Investors section of our website, http://www.stereotaxis.com, as soon asreasonably practicable after they are filed with the SEC.

We cannot be certain that we willbe able to obtain additional funds on favorable terms or at all. If we cannot raise capital on acceptable terms, we will not be able to, among other things: • service our debt obligations and meet our financial covenants; • maintain customer and vendor relationships; • hire, train and retain employees; • maintain or expand our operations; • enhance our existing products or develop new ones; or • respond to competitive pressures.Our failure to do any of these things could result in lower revenue and adversely affect our financial condition and results of operations, and we mayhave to curtail or cease operations.Our auditors have expressed substantial doubt regarding our ability to continue as a going concern. If we are unable to continue as a goingconcern, we may be required to substantially revise our business plan or cease operations.As of December 31, 2013, we had cash and cash equivalents of $13.8 million and working capital of $4.4 million. We incurred operating losses of $8.8million, $10.6 million, and $31.9 million in 2013, 2012 and 2011, respectively. As a result, our auditors have expressed substantial doubt about our abilityto continue as a going concern. Our auditors included an explanatory paragraph regarding our ability to continue as a going concern in their auditors’ report onour 2011 and 2012 financial statements as well. We cannot assure you that we will be able to obtain sufficient funds from our operating or financing activitiesto support our continued operations. If we cannot continue as a going concern, we may need to substantially revise our business plan or cease operations,which may reduce or negate the value of your investment. In addition, our continued receipt of an opinion from our auditors that expresses doubt about ourability to continue as a going concern may impair our ability to raise new capital, obtain new customers, and hire and retain employees.We may not be able to comply with debt covenants and may have to repay outstanding indebtedness.We have financed our operations through equity transactions, a financing of our catheter royalty stream under the Healthcare Royalty Partners II, L.P.(formerly “Cowen Healthcare Royalty Partners II, L.P.”) facility entered into in November 2011, as well as bank and other borrowings. In the third quarter of2013, we extended our revolving line of credit, which matures on March 31, 2014. In addition, our current borrowing agreements contain various covenants,including financial covenants under our credit agreement with our primary lender. The covenants in these various agreements are similar, but are not identicalin all respects. If we violate our covenants, we could be required to repay the indebtedness as to which that default relates. In addition, as a result of variouscross-default provisions in these agreements, a violation of the covenants under one or more of such agreements could trigger our obligation to repay all of ourexisting indebtedness. We could be unable to make these payments, which could lead to insolvency. Even if we are able to make these payments, it will lead tothe lack of availability for additional borrowings under our bank loan agreement due to our borrowing capacity. There can be no assurance that we will be ableto maintain compliance with these covenants or that we could replace this source of liquidity if these covenants were to be violated and our loans and otherborrowed amounts were forced to be repaid. 22We may lose key personnel or fail to attract and retain replacement or additional personnel.We are highly dependent on the principal members of our management, as well as our scientific and sales staff. Attracting and retaining qualifiedpersonnel will be critical to our success, and competition for qualified personnel is intense. We may not be able to attract and retain personnel on acceptableterms given the competition for qualified personnel among technology and healthcare companies and universities. The loss of personnel, in particular seniorexecutives, or our inability to attract and retain other qualified personnel could harm our business and our ability to compete. In addition, the loss of membersof our scientific staff may significantly delay or prevent product development and other business objectives. A loss of key sales personnel could result in areduction of revenue. In addition, if we outsource certain employee functions that were formerly handled in-house, our personnel costs could increase.Hospital decision-makers may not purchase our Niobe, Odyssey, or Vdrive systems or may think that such systems are too expensive.To achieve and grow sales, hospitals must purchase our products, and in particular, our Niobe ES system. The Niobe ES system is a novel device,and hospitals and physicians are traditionally slow to adopt new products and treatment practices. In addition, hospitals may delay their purchase orinstallation decision for the Niobe ES system based on the disposable interventional devices that have received regulatory clearance or approval. Moreover, theNiobe ES system is an expensive piece of capital equipment, representing a significant portion of the cost of a new or replacement interventional lab. Althoughpriced significantly below a Niobe ES system, the Odyssey Solution and Vdrive system are still expensive products. If hospitals do not widely adopt oursystems, or if they decide that they are too expensive, we may never become profitable. Any failure to sell as many systems as our business plan requirescould also have a seriously detrimental impact on our results of operations, financial condition, and cash flow.If we are unable to fulfill our current purchase orders and other commitments on a timely basis or at all, we may not be able to achieve futuresales growth.Our backlog, which consists of purchase orders and other commitments, is considered by some investors to be a significant indicator of futureperformance. Consequently, negative changes to this backlog or its failure to grow commensurate with expectations could negatively impact our futureoperating results or our share price. Our backlog includes those outstanding purchase orders and other commitments that management believes will result inrecognition of revenue upon delivery or installation of our systems. We cannot assure you that we will recognize revenue in any particular period or at allbecause some of our purchase orders and other commitments are subject to contingencies that are outside our control. In addition, these orders andcommitments may be revised, modified or cancelled, either by their express terms, as a result of negotiations or by project changes or delays. Systeminstallation is by its nature subject to the interventional lab construction or renovation process which comprises multiple stages, all of which are outside of ourcontrol. Although the actual installation of our Niobe ES system requires only a few weeks, and can be accomplished by either our staff or by subcontractors,successful installation of our system can be subjected to delays related to the overall construction or renovation process. If we experience any failures or delaysin completing the installation of these systems, our reputation would suffer and we may not be able to sell additional systems. We have experienced situationsin which our purchase orders and other commitments did not result in recognizing revenue from placement of a system with a customer. In addition toconstruction delays, there are risks that an institution will attempt to cancel a purchase order as a result of subsequent project review by the institution or thedeparture from the institution of physicians or physician groups who have expressed an interest in the Epoch Solution.In 2013, 2012 and 2011, we experienced decreases in our backlog. These, or similar events, have occurred in the past and are likely to occur in thefuture, causing delays in revenue recognition or even removal of orders and other commitments from our backlog. Such events would have a negative effect onour revenue and results of operations. 23We will likely experience long and variable sales and installation cycles, which could result in substantial fluctuations in our quarterly results ofoperations.We anticipate that our Niobe ES system will continue to have a lengthy sales cycle because it consists of a relatively expensive piece of capitalequipment, the purchase of which requires the approval of senior management at hospitals, inclusion in the hospitals’ interventional lab budget process forcapital expenditures, and, in some instances, a certificate of need from the state or other regulatory approval. In addition, historically the majority of our NiobeES systems and Odyssey systems have been delivered less than one year after the receipt of a purchase order from a hospital, with the timing being dependenton the construction cycle for the new or replacement interventional suite in which the equipment will be installed. In some cases, this time frame has beenextended further because the interventional suite construction is part of a larger construction project at the customer site (typically the construction of a newbuilding), which may occur with our existing and future purchase orders. We cannot assure you that the time from purchase order to delivery for systems tobe delivered in the future will be consistent with our historical experience. Moreover, the global economic slowdown may cause our customers to further delayconstruction or significant capital purchases, which could further lengthen our sales cycle. This may contribute to substantial fluctuations in our quarterlyoperating results. As a result, in future quarters our operating results could fall below the expectations of securities analysts or investors, in which event ourstock price would likely decrease.The rate of technological innovation of our products might not keep pace with the rest of the market.The rate of innovation for the market in which our products compete is fast-paced and requires significant resources and innovation. If other productsand technologies are developed that compete with, or may compete with, the Niobe, Odyssey and Vdrive systems, it could be difficult for us to maintain ouradvantages associated with being an early developer of this technology. In addition, connectivity with other devices in the electrophysiology lab is a key driverof value. If the Company is not able to continue to commit sufficient resources to ensure that its products are compatible with other products within theelectrophysiology lab, this could have a negative impact on revenue.General economic conditions could materially adversely impact us.Our operating performance is dependent upon economic conditions in the United States and in other countries in which we operate. The recent economicdownturn or the lack of a robust recovery in the United States and in other countries in which we sell our products may cause customers to delay purchasingor installation decisions or cancel existing orders. The Niobe ES system, Odyssey Solution and Vdrive system are typically purchased as part of a largeroverall capital project and an economic downturn or the lack of a robust recovery might make it more difficult for our customers, including distributors, toobtain adequate financing to support the project or to obtain requisite approvals. Any delay in purchasing decisions or cancellation of purchasingcommitments may result in a decrease in our revenues. Another credit crisis similar to the credit crisis that began in 2008 could further affect our business ifkey suppliers are unable to obtain financing to manufacture our products or become insolvent and we are unable to manufacture product to meet customerdemand. If the United States and global economy continues to be sluggish or deteriorates further for a longer period than we anticipate, we may experience amaterial negative decrease on the demand for our products which may, in turn, have a material adverse effect on our revenue, profitability, financial condition,ability to raise additional capital and the market price of our stock.Physicians may not use our products if they do not believe they are safe, efficient and effective.We believe that physicians will not use our products unless they determine that the Niobe ES system and Vdrive system provide a safe, effective andpreferable alternative to interventional methods in general use today. If longer-term patient studies or clinical experience indicate that treatment with our systemor products is less effective, less efficient or less safe than our current data suggest, our sales would be harmed, and we could be 24subject to significant liability. Further, unsatisfactory patient outcomes or patient injury could cause negative publicity for our products, particularly in theearly phases of product introduction. In addition, physicians may be slow to adopt our products if they perceive liability risks arising from the use of thesenew products. It is also possible that as our products become more widely used, latent defects could be identified, creating negative publicity and liabilityproblems for us and adversely affecting demand for our products. If physicians do not use our products, we likely will not become profitable or generatesufficient cash to survive as a going concern.Our collaborations with Siemens, Philips, Biosense Webster or other parties may fail, or we may not be able to enter into additional alliances orcollaborations in the future.We have collaborated with and are continuing to collaborate with Siemens, Philips, Biosense Webster and other parties to integrate our instrument controltechnology with their respective imaging products or disposable interventional devices and to co-develop additional disposable interventional devices for usewith our Niobe system. A significant portion of our revenue from system sales is derived from these integrated products.Our product commercialization plans could be disrupted, leading to lower than expected revenue and a material and adverse impact on our results ofoperations and cash flow, if: • we fail to or are unable to maintain adequate compatibility of our products with the most prevalent imaging products or disposable interventionaldevises expected by our customers for their clinical practice; • any of our collaboration partners delays or fails in the integration of its technology with our Niobe system; • any of our collaboration partners fails to develop or commercialize the integrated products in a timely manner; or • we become involved in disputes with one or more of our collaboration partners regarding our collaborations.Siemens, Philips and Biosense Webster, as well as some of our other collaborators, are large, global organizations with diverse product lines andinterests that may diverge from our interests in commercializing our products. Accordingly, our collaborators may not devote adequate resources to ourproducts, or may experience financial difficulties, change their business strategy or undergo a business combination that may affect their willingness or abilityto fulfill their obligations to us.The failure of one or more of our collaborations could have a material adverse effect on our financial condition, results of operations and cash flow. Inaddition, if we are unable to enter into additional collaborations in the future, or if these collaborations fail, our ability to develop and commercialize productscould be impacted negatively and our revenue could be adversely affected.The complexity associated with selling, marketing, and distributing products could impair our ability to increase revenue.We currently market our products in the U.S., Europe and the rest of the world through a direct sales force of sales specialists, distributors and salesagents, supported by account managers and clinical specialists who provide training, clinical support, and other services to our customers. If we are unable toeffectively utilize our existing sales force or increase our existing sales force in the foreseeable future, we may be unable to generate the revenue we haveprojected in our business plan. Factors that may inhibit our sales and marketing efforts include: • our inability to recruit and retain adequate numbers of qualified sales and marketing personnel; 25 • our inability to accurately forecast future product sales and utilize resources accordingly; • the inability of sales personnel to obtain access to or persuade adequate numbers of hospitals and physicians to purchase and use our products;and • unforeseen costs associated with maintaining and expanding an independent sales and marketing organization.In addition, if we fail to effectively use distributors or contract sales agents for distribution of our products where appropriate, our revenue andprofitability would be adversely affected.Our marketing strategy is dependent on collaboration with physician “thought leaders.”Our research and development efforts and our marketing strategy depend heavily on obtaining support, physician training assistance, and collaborationfrom highly regarded physicians at leading commercial and research hospitals, particularly in the U.S. and Europe. If we are unable to gain and/or maintainsuch support, training services, and collaboration or if the reputation or standing of these physicians is impaired or otherwise adversely affected, our ability tomarket our products and, as a result, our financial condition, results of operations and cash flow could be materially and adversely affected.Physicians may not commit enough time to sufficiently learn our system.In order for physicians to learn to use the Niobe system, they must attend structured training sessions in order to familiarize themselves with asophisticated user interface and they must be committed to learning the technology. Further, physicians must utilize the technology on a regular basis to ensurethey maintain the skill set necessary to use the interface. Continued market acceptance could be delayed by lack of physician willingness to attend trainingsessions, by the time required to complete this training, or by state or institutional restrictions on our ability to provide training. An inability to train asufficient number of physicians to generate adequate demand for our products could have a material adverse impact on our financial condition and cash flow.Customers may choose to purchase competing products and not ours.Our products must compete with established manual interventional methods. These methods are widely accepted in the medical community, have a longhistory of use and do not require the purchase of an additional expensive piece of capital equipment. In addition, many of the medical conditions that can betreated using our products can also be treated with existing pharmaceuticals or other medical devices and procedures. Many of these alternative treatments arewidely accepted in the medical community and have a long history of use.We also face competition from companies that are developing drugs or other medical devices or procedures to treat the conditions for which our productsare intended. The medical device and pharmaceutical industries make significant investments in research and development, and innovation is rapid andcontinuous. Other companies in the medical device industry continue to develop new devices and technologies for manual intervention methods. We are awareof one public company that has commercialized a catheter delivery system which has been cleared by the FDA for mapping procedures only. In addition, weare aware of one private company with an electro-magnetic catheter delivery system that has received CE Mark approval in Europe. We also face competitionfrom companies who currently market or are developing drugs, gene or cellular therapies to treat the conditions for which our products are intended. If these orother new products or technologies emerge that provide the same or superior benefits as our products at equal or lesser cost, it could render our productsobsolete or unmarketable. In addition, the presence of other competitors may cause potential customers to delay their purchasing decisions, resulting in a longerthan expected sales cycle, even if they do not choose our competitors’ products. We cannot be certain that physicians will use our products to replace orsupplement established treatments or that our products will be competitive with current or future products and technologies. 26Many of our other competitors also have longer operating histories, significantly greater financial, technical, marketing and other resources, greater namerecognition and a larger base of customers than we do. In addition, as the markets for medical devices develop, additional competitors could enter the market.We cannot assure you that we will be able to compete successfully against existing or new competitors. Our revenue would be reduced or eliminated if ourcompetitors develop and market products that are more effective and less expensive than our products.If the magnetic fields generated by our system are not compatible with, or interfere with, other widely used equipment in the interventional labs,sales of our products would be negatively affected.Our Niobe system generates magnetic fields that directly govern the motion of the internal, or working, tip of disposable interventional devices. If otherequipment in the interventional labs or elsewhere in a hospital is incompatible with the magnetic fields generated by our system, or if our system interferes withsuch equipment, we may be required to install additional shielding, which may be expensive and which may not solve the problem. If magnetic interferencebecomes a significant issue at targeted institutions, it would increase our installation costs at those institutions and could limit the number of hospitals thatwould be willing to purchase and install our systems, either of which would adversely affect our financial condition, results of operations and cash flow.The use of our products could result in product liability claims that could be expensive, divert management’s attention, and harm our reputationand business.Our business exposes us to significant risks of product liability claims. The medical device industry has historically been litigious, and we could faceproduct liability claims if the use of our products were to cause injury or death. The coverage limits of our product liability insurance policies may not beadequate to cover future claims, and we may be unable to maintain product liability insurance in the future at satisfactory rates or adequate amounts. Aproduct liability claim, regardless of its merit or eventual outcome, could divert management’s attention, and result in significant legal defense costs,significant harm to our reputation and a decline in revenue.Our costs could substantially increase if we receive a significant number of warranty claims.We generally warrant each of our products against defects in materials and workmanship for a period of 12 months following the installation of oursystem. If product returns or warranty claims increase, we could incur unanticipated additional expenditures for parts and service. In addition, our reputationand goodwill in the interventional lab market could be damaged. Unforeseen warranty exposure in excess of our established reserves for liabilities associatedwith product warranties could materially and adversely affect our financial condition, results of operations and cash flow.We have incurred substantial losses in the past and may not be profitable in the future.We have incurred substantial net losses since inception, and we expect to incur net losses into 2014 as we continue the commercialization of ourproducts. We are still in the process of realizing the full potential of the commercialization of our technology, and will need to continue to make improvementsto that technology. Moreover, the extent of our future losses and the timing of profitability are highly uncertain, and we may never achieve profitable operations.If we require more time than we expect to generate significant revenue and achieve profitability, we may not be able to continue our operations. Our failure toachieve profitability could negatively impact the market price of our common stock. Even if we do become profitable, we may not be able to sustain or increaseprofitability on a quarterly or annual basis. Furthermore, even if we achieve significant revenue, we may choose to pursue a strategy of increasing marketpenetration and presence or expand or accelerate new product development or clinical research activities at the expense of profitability. 27Our reliance on contract manufacturers and on suppliers, and in some cases, a single supplier, could harm our ability to meet demand for ourproducts in a timely manner or within budget.We depend on contract manufacturers to produce and assemble certain of the components of our systems and other products such as ourelectrophysiology catheter advancement device, guidewires and disposable devices for our Vdrive system. We also depend on various third party suppliers forthe magnets we use in our Niobe ES system and certain components of our Odyssey Solution and Vdrive system. In addition, some of the componentsnecessary for the assembly of our products are currently provided to us by a single supplier, including the magnets for our Niobe ES system and certaincomponents of our Odyssey Solution, and we generally do not maintain large volumes of inventory. Our reliance on these third parties involves a number ofrisks, including, among other things, the risk that: • we may not be able to control the quality and cost of our system or respond to unanticipated changes and increases in customer orders; • we may lose access to critical services, materials, or components, resulting in an interruption in the manufacture, assembly and shipment of oursystems; and • we may not be able to find new or alternative components for our use or reconfigure our system and manufacturing processes in a timely mannerif the components necessary for our system become unavailable.If any of these risks materialize, it could significantly increase our costs and impair product delivery.Lead times for materials and components ordered by us and our contract manufacturers vary and depend on factors such as the specific supplier,contract terms and demand for a component at a given time. We and our contract manufacturers acquire materials, complete standard subassemblies andassemble fully configured systems based on sales forecasts. If orders do not match forecasts, our contract manufacturers and we may have excess orinadequate inventory of materials and components.In addition, if these manufacturers or suppliers stop providing us with the components or services necessary for the operation of our business, we maynot be able to identify alternate sources in a timely fashion. Any transition to alternate manufacturers or suppliers would likely result in operational problemsand increased expenses and could delay the shipment of, or limit our ability to provide, our products. We cannot assure you that we would be able to enter intoagreements with new manufacturers or suppliers on commercially reasonable terms or at all. Additionally, obtaining components from a new supplier mayrequire a new or supplemental filing with applicable regulatory authorities and clearance or approval of the filing before we could resume product sales. Anydisruptions in product flow may harm our ability to generate revenue, lead to customer dissatisfaction, damage our reputation and result in additional costs orcancellation of orders by our customers.We also rely on Biosense Webster and other parties to manufacture a number of disposable interventional devices for use with our Niobe system. If theseparties cannot manufacture sufficient quantities of disposable interventional devices to meet customer demand, or if their manufacturing processes aredisrupted, our revenue and profitability would be adversely affected.Risks associated with international manufacturing and trade could negatively impact the availability and cost of our products becausematerials used to manufacture our magnets, one of our key system components, are sourced from overseas.We purchase the permanent magnets for our Niobe ES system from a manufacturer that uses material produced in Japan, and we anticipate that certainof the production work for these magnets will be performed for this manufacturer in China. In addition, our subcontractor purchases magnets for ourdisposable interventional devices directly from a manufacturer in Japan. Any event causing a significant increase in price or a disruption of imports, includingthe imposition of import restrictions, could adversely affect our business. The flow of 28components from our vendors could also be adversely affected by financial or political instability in any of the countries in which the goods we purchase aremanufactured, if the instability affects the production or export of product components from those countries. Trade restrictions in the form of tariffs orquotas, or both, could also affect the importation of those product components and could increase the cost and reduce the supply of products available to us.In addition, decreases in the value of the U.S. dollar against foreign currencies could increase the cost of products we purchase from overseas vendors.We may encounter problems at our manufacturing facilities or those of our subcontractors or otherwise experience manufacturing delays thatcould result in lost revenue.We subcontract the manufacture and assembly of components of our Niobe ES system, Odyssey Solution, and Vdrive system, and all of ourdisposable devices. The products we design may not satisfy all of the performance requirements of our customers and we may need to improve or modify thedesign or ask our subcontractors to modify their production process in order to do so. In addition, we or our subcontractors may experience quality problems,substantial costs and unexpected delays related to efforts to upgrade and expand manufacturing, assembly and testing capabilities. If we incur delays due toquality problems or other unexpected events, our revenue may be impacted.We may be unable to protect our technology from use by third parties.Our commercial success will depend in part on obtaining patent and other intellectual property right protection for the technologies contained in ourproducts and on successfully defending these rights against third party challenges. The patent positions of medical device companies, including ours, can behighly uncertain and involve complex and evolving legal and factual questions. We cannot assure you that we will obtain the patent protection we seek, thatany protection we do obtain will be found valid and enforceable if challenged or that it will confer any significant commercial advantage. U.S. patents andpatent applications may also be subject to interference proceedings and U.S. patents may be subject to re-examination proceedings in the U.S. Patent andTrademark Office, and foreign patents may be subject to opposition or comparable proceedings in the corresponding foreign patent office, which proceedingscould result in either loss of the patent or denial of the patent application or loss, or reduction in the scope of one or more of the claims of, the patent or patentapplication. In addition, such interference, re-examination, and opposition proceedings may be costly. Thus, any patents that we own or license from othersmay not provide any protection against competitors. Our pending patent applications, those we may file in the future, or those we may license from thirdparties may not result in patents being issued and certain foreign patent applications for medical related devices and methods may be found unpatentable. Ifissued, they may not provide us with proprietary protection or competitive advantages against competitors with similar technology.Some of our technology was developed in conjunction with third parties, and thus there is a risk that a third party may claim rights in our intellectualproperty. Outside the U.S., we rely on third-party payment services for the payment of foreign patent annuities and other fees. Non-payment or delay inpayment of such fees, whether intentional or unintentional, may result in loss of patents or patent rights important to our business. Many countries, includingcertain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties (for example, thepatent owner has failed to “work” the invention in that country, or the third party has patented improvements). In addition, many countries limit theenforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which couldmaterially diminish the value of the patent. We also cannot assure you that we will be able to develop additional patentable technologies. If we fail to obtainadequate patent protection for our technology, or if any protection we obtain becomes limited or invalidated, others may be able to make and sell competingproducts, impairing our competitive position.Our trade secrets, nondisclosure agreements and other contractual provisions to protect unpatented technology provide only limited and possiblyinadequate protection of our rights. As a result, third parties may be 29able to use our unpatented technology, and our ability to compete in the market would be reduced. In addition, employees, consultants and others whoparticipate in developing our products or in commercial relationships with us may breach their agreements with us regarding our intellectual property, and wemay not have adequate remedies for the breach.Our competitors may independently develop similar or alternative technologies or products that are equal or superior to our technology and productswithout infringing any of our patent or other intellectual property rights, or may design around our proprietary technologies. Our competitors may acquiresimilar or even the same technology components that are utilized in our current offering eroding some differentiation in the marketplace. In addition, the laws ofsome foreign countries do not protect intellectual property rights to the same extent, as do the laws of the U.S., particularly in the field of medical products andprocedures.Third parties may assert that we are infringing their intellectual property rights.Successfully commercializing our products will depend in part on not infringing patents held by third parties. It is possible that one or more of ourproducts, including those that we have developed in conjunction with third parties, infringes existing patents. We may also be liable for patent infringement bythird parties whose products we use or combine with our own and for which we have no right to indemnification. In addition, because patent applications aremaintained under conditions of confidentiality and can take many years to issue, there may be applications now pending of which we are unaware and whichmay later result in issued patents that our products infringe. Determining whether a product infringes a patent involves complex legal and factual issues andmay not become clear until finally determined by a court in litigation. Our competitors may assert that our products infringe patents held by them. Moreover,as the number of competitors in our market grows the possibility of a patent infringement claim against us increases. If we were not successful in obtaining alicense or redesigning our products, we could be subject to litigation. If we lose in this kind of litigation, a court could require us to pay substantial damages orprohibit us from using technologies essential to our products covered by third-party patents. An inability to use technologies essential to our products wouldhave a material adverse effect on our financial condition, results of operations and cash flow and could undermine our ability to continue operating as a goingconcern.Expensive intellectual property litigation is frequent in the medical device industry.Infringement actions, validity challenges and other intellectual property claims and proceedings, whether with or without merit, can be expensive andtime-consuming and would divert management’s attention from our business. We have incurred, and expect to continue to incur, substantial costs in obtainingpatents and may have to incur substantial costs defending our proprietary rights. Incurring such costs could have a material adverse effect on our financialcondition, results of operations and cash flow.We may not be able to maintain all the licenses or rights from third parties necessary for the development, manufacture, or marketing of newand existing products.As we develop additional products and improve or maintain existing products, we may find it advisable or necessary to seek licenses or otherwise makepayments in exchange for rights from third parties who hold patents covering certain technology. If we cannot obtain or maintain the desired licenses or rightsfor any of our products, we could be forced to try to design around those patents at additional cost or abandon the product altogether, which could adverselyaffect revenue and results of operations. If we have to abandon a product, our ability to develop and grow our business in new directions and markets wouldbe adversely affected. If we do not maintain licenses or exclusivity with suppliers of certain components of our Odyssey Solution, competitors may enter themarket, negatively impacting our ability to develop and commercialize the Odyssey Solution.Our products and related technologies can be applied in different medical applications, and we may fail to focus on the most profitable areas.The Niobe system is designed to have the potential for expanded applications beyond electrophysiology and interventional cardiology, includingcongestive heart failure, structural heart repair, interventional neurosurgery, 30interventional neuroradiology, peripheral vascular, pulmonology, urology, gynecology and gastrointestinal medicine. We continue to develop the OdysseySolution and Vdrive system for interventional labs that have a Niobe system installed as well as those standard interventional labs that do not have a Niobesystem installed. However, we have limited financial and managerial resources and therefore may be required to focus on products in selected industries andsites and to forego efforts with regard to other products and industries. Our decisions may not produce viable commercial products and may divert ourresources from more profitable market opportunities. Moreover, we may devote resources to developing products in these additional areas but may be unable tojustify the value proposition or otherwise develop a commercial market for products we develop in these areas, if any. In that case, the return on investment inthese additional areas may be limited, which could negatively affect our results of operations.We may be subject to damages resulting from claims that our employees or we have wrongfully used or disclosed alleged trade secrets of theirformer employers.Many of our employees were previously employed at hospitals, universities or other medical device companies, including our competitors or potentialcompetitors. We could in the future be subject to claims that these employees or we have used or disclosed trade secrets or other proprietary information of theirformer employers. Litigation may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages,we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against these claims, litigation could result in substantialcosts and be a distraction to management. Incurring such costs could have a material adverse effect on our financial condition, results of operations and cashflow.If we or the parties in our strategic alliances fail to obtain or maintain necessary FDA clearances or approvals for our medical device products,or if such clearances or approvals are delayed, we will be unable to continue to commercially distribute and market our products.Our products are medical devices that are subject to extensive regulation in the U.S. and in foreign countries where we do business. Unless an exemptionapplies, each medical device that we wish to market in the U.S. must be designated as Class I, exempt from premarket approval or notification or first receiveeither a 510(k) clearance or a pre-market approval, or PMA, from the U.S. FDA pursuant to the Federal Food, Drug, and Cosmetic Act, or FD&C Act. TheFDA’s 510(k) clearance process usually takes from four to 12 months, but it can take longer. The process of obtaining PMA approval is much more costly,lengthy, and uncertain, generally taking from one to three years or even longer. Although we have 510(k) clearance for many of our products, includingdisposable interventional devices, and we are able to market these products commercially in the U.S., our business model relies significantly on revenue fromdisposable interventional devices, some of which may not achieve FDA clearance or approval. We cannot assure you that any of our devices will not berequired to undergo the lengthier and more burdensome PMA process. We cannot commercially market any disposable interventional devices in the U.S. untilthe necessary clearances or approvals from the FDA have been received. In addition, we are working with third parties to co-develop disposable products. Insome cases, these companies are responsible for obtaining appropriate regulatory clearance or approval to market these disposable devices. If these clearancesor approvals are not received or are substantially delayed or if we are not able to offer a sufficient array of approved disposable interventional devices, we maynot be able to successfully market our system to as many institutions as we currently expect, which could have a material adverse impact on our financialcondition, results of operations and cash flow.Furthermore, obtaining 510(k) clearances, PMAs or PMA supplement approvals, from the FDA could result in unexpected and significant costs for usand consume management’s time and other resources. The FDA could ask us to supplement our submissions, collect non-clinical data, conduct clinical trialsor engage in other time-consuming actions, or it could simply deny our applications. In addition, even if we obtain a 510(k) clearance or PMA or PMAsupplement approval, the clearance or approval could be revoked or other restrictions imposed if post-market data demonstrates safety issues or lack ofeffectiveness. We cannot predict with certainty how, or 31when, the FDA will act on our marketing applications. If we are unable to obtain the necessary regulatory approvals, our financial condition and cash flowmay be adversely affected. Also, a failure to obtain approvals may limit our ability to grow domestically and internationally.If our strategic alliances elect not to or we fail to obtain regulatory approvals in other countries for products under development, we will not beable to commercialize these products in those countries.In order to market our products outside of the U.S., we and our strategic partners or distributors must establish and comply with numerous andvarying regulatory requirements of other countries regarding safety and efficacy. Approval procedures vary among countries and can involve additionalproduct testing and additional administrative review periods. The time required to obtain approval in other countries might differ from that required to obtainFDA approval. The regulatory approval process in other countries may include all of the risks detailed above regarding FDA approval in the U.S. Regulatoryapproval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may negativelyimpact the regulatory process in others. Failure to obtain regulatory approval in other countries or any delay or setback in obtaining such approval could havethe same adverse effects described above regarding FDA approval in the U.S. In addition, we are relying on our strategic alliances in some instances to assistus in this regulatory approval process in countries outside the U.S. and Europe, for example, in Japan.We may fail to comply with continuing regulatory requirements of the FDA and other authorities and become subject to enforcement action,which may include substantial penalties.Even after product clearance or approval, we must comply with continuing regulation by the FDA and other authorities, including the FDA’s QualitySystem Regulation, or QSR, requirements, labeling and promotional requirements and medical device adverse event and other reporting requirements. Anyfailure to comply with continuing regulation by the FDA or other authorities could result in enforcement action that may include suspension or withdrawal ofregulatory approvals, recalling products, ceasing product manufacture and/or marketing, seizure and detention of products, paying significant fines andpenalties, criminal prosecution and similar actions that could limit product sales, delay product shipment and harm our profitability. Congress could amendthe FD&C Act, and the FDA could modify its regulations promulgated under this law in a way to make ongoing regulatory compliance more burdensome anddifficult.Additionally, any modification to an FDA 510(k)-cleared device that could significantly affect its safety or effectiveness, or that would constitute amajor change in its intended use, requires a new 510(k) clearance. Modifications to a PMA approved device or its labeling may require either a new PMA orPMA supplement approval, which could be a costly and lengthy process. In addition, if we are unable to obtain on-label approval for key applications, wemay face product market adoption barriers that we cannot overcome. In the future, we may modify our products after they have received clearance orapproval, and we may determine that new clearance or approval is unnecessary. We cannot assure you that the FDA would agree with any of our decisions notto seek new clearance or approval. If the FDA requires us to seek clearance or approval for any modification, we could be subject to enforcement sanctions andwe also may be required to cease marketing or recall the modified product until we obtain FDA clearance or approval which could also limit product sales,delay product shipment and harm our profitability.In many foreign countries in which we market our products, we are subject to regulations affecting, among other things, product standards, packagingrequirements, labeling requirements, import restrictions, tariff regulations, duties and tax requirements. Many of these regulations are similar to those of theFDA or other U.S. regulations. In addition, in many countries the national health or social security organizations require our products to be qualified beforeprocedures performed using our products become eligible for reimbursement. Failure to receive or delays in the receipt of, relevant foreign qualifications couldhave a material adverse effect on our business, financial condition and results of operations. Due to the movement toward harmonization of standards in theEuropean Union, we expect a changing regulatory environment in Europe characterized by a 32shift from a country-by-country regulatory system to a European Union-wide single regulatory system. We cannot predict the timing of this harmonization andits effect on us. Adapting our business to changing regulatory systems could have a material adverse effect on our business, financial condition, and results ofoperations. If we fail to comply with applicable foreign regulatory requirements, we may be subject to fines, suspension, or withdrawal of regulatoryapprovals, product recalls, seizure of products, operating restrictions and criminal prosecution.In addition, we are subject to the U.S. Foreign Corrupt Practices Act, anti-bribery, antitrust and anti-competition laws, and similar laws in foreigncountries. Any violation of these laws by our distributors or agents or by us could create a substantial liability for us and also cause a loss of reputation in themarket. From time to time, we may face audits or investigations by one or more government agencies, compliance with which could be costly and time-consuming, and could divert our management and key personnel from our business operations. An adverse outcome under any such investigation or auditcould subject us to fines or other penalties, which could adversely affect our business and financial results.Our suppliers, subcontractors, or we may fail to comply with the FDA quality system regulation.Our manufacturing processes must comply with the FDA’s quality system regulation, or QSR, which covers the methods and documentation of thedesign, testing, production, control, quality assurance, labeling, packaging and shipping of our products. The FDA enforces the QSR through inspections.We cannot assure you that we or our suppliers or subcontractors would pass such an inspection. If we or our suppliers or subcontractors fail to remain incompliance with the FDA or EN 13485:2003 standards, we or they may be required to cease all or part of our operations for some period of time until we orthey can demonstrate that appropriate steps have been taken to comply with such standards or face other enforcement action, such as a public warning letter.We cannot be certain that our facilities or those of our suppliers or subcontractors will comply with the FDA or EN 13485:2003 standards in future audits byregulatory authorities. Failure to pass such an inspection could force a shutdown of manufacturing operations, a recall of our products or the imposition ofother enforcement sanctions, which would significantly harm our revenue and profitability. Further, we cannot assure you that our key component suppliersare or will continue to be in compliance with applicable regulatory requirements and quality standards and will not encounter any manufacturing difficulties.Any failure to comply with the FDA’s QSR or EN 13485:2003 by us or our suppliers could significantly harm our available inventory and product sales.Further, any failure to comply with FDA’s QSR by us or our suppliers could result in FDA refusing requests for and/or delays in 510(k) clearance or PMAapproval of new products.Software errors or other defects may be discovered in our products.Our products incorporate many components, including sophisticated computer software. Complex software frequently contains errors, especially whenfirst introduced. Because our products are designed to be used to perform complex interventional procedures, we expect that physicians and hospitals will havean increased sensitivity to the potential for software defects. We cannot assure you that our software or other components will not experience errors orperformance problems in the future. If we experience software errors or performance problems, we would likely also experience: • loss of revenue; • delay in market acceptance of our products; • damage to our reputation; • additional regulatory filings; • product recalls; • increased service or warranty costs; and/or • product liability claims relating to the software defects. 33If we fail to comply with health care regulations, we could face substantial penalties and our business, operations and financial condition couldbe adversely affected.While we do not control referrals of health care services or bill directly to Medicare, Medicaid or other third-party payors, many health care laws andregulations apply to our business. We are subject to health care fraud and patient privacy regulation by the federal government, the states in which we conductour business, and internationally. The regulations that may affect our ability to operate include: • the federal healthcare program Anti-Kickback Law, which prohibits, among other things, persons from soliciting, receiving or providingremuneration, directly or indirectly, to induce either the referral of an individual, for an item or service or the purchasing or ordering of a good orservice, for which payment may be made under federal health care programs such as the Medicare and Medicaid programs; • federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented,claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent, and which may apply to entities like us ifwe provide coding and billing advice to customers; • the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which prohibits executing a scheme to defraud any healthcare benefit program or making false statements relating to health care matters and which also imposes certain requirements relating to the privacy,security and transmission of individually identifiable health information; and the applicable Privacy and Security Standards of HITECH, theHealth Information Technology for Economic and Clinical Health Act, which is Title XIII of the American Recovery and Reinvestment Act; • state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or servicesreimbursed by any third-party payor, including commercial insurers, and state laws governing the privacy of health information in certaincircumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating complianceefforts; • federal self-referral laws, such as the Stark Anti-Referral Law, which prohibits a physician from making a referral to a provider of certain healthservices with which the physician or the physician’s family member has a financial interest; • federal and state Sunshine laws, which require manufacturers of certain medical devices to collect and report information on payments ortransfers of value to physicians and teaching hospitals, as well as investment interests held by physicians and their immediate family members;and • regulations pertaining to receipt of CE mark for our products marketed outside of the United States and submission to periodic regulatory auditsin order to maintain these regulatory approvals.If our operations are found to be in violation of any of the laws described above or any other governmental laws or regulations that apply to us, we maybe subject to penalties, including civil and criminal penalties, damages, fines, loss of reimbursement for our products under federal or state government healthprograms such as Medicare and Medicaid and the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment, or restructuringof our operations could adversely affect our ability to operate our business and our financial results. The risk of our being found in violation of these laws isincreased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety ofinterpretations. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenseand divert our management’s attention from the operation of our business. Moreover, to achieve compliance with applicable federal and state privacy, security,and electronic transaction laws, we may be required to modify our operations with respect to the handling of patient information. Implementing thesemodifications may prove costly. At this time, we are not able to determine the full consequences to us, including the total cost of compliance, of these variousfederal and state laws. 34Healthcare policy changes, including legislation enacted in 2010, may have a material adverse effect on us.In response to perceived increases in health care costs in recent years, there have been and continue to be proposals by the Obama administration,members of Congress, state governments, regulators and third-party payors to control these costs and, more generally, to reform the U.S. healthcare system.In March 2010, the President signed into law the Patient Protection and Affordable Care Act (PPACA). Among other things, the law imposes a tax onmedical device manufacturers and producers equal to 2.3% of the sales price for all sales beginning January 1, 2013. This excise tax applies to the majority ofour products sold within the United States. We expect that the PPACA could have a material adverse effect on our industry generally and our ability tosuccessfully commercialize our products or could limit or eliminate our spending on certain development projects.On August 2, 2011, the President signed into law the Budget Control Act of 2011, which created the Joint Select Committee on Deficit Reduction torecommend proposals in spending reductions to Congress. The Joint Select Committee was charged with identifying a reduction of at least $1.2 trillion for theyears 2013 through 2021. The Committee did not achieve this target by the imposed deadline, triggering the legislation’s automatic reduction to severalgovernment programs. Included in the automatic reduction are aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, starting in2013.The taxes imposed by the PPACA, the expansion in the government’s role in the U.S. healthcare industry, and other healthcare reform measures at thefederal and state level that may be adopted in the future could have a material, negative impact on our results of operations and our cash flows.The application of state certificate of need regulations and compliance by our customers with federal and state licensing or other internationalrequirements could substantially limit our ability to sell our products and grow our business.Some states require health care providers to obtain a certificate of need or similar regulatory approval prior to the acquisition of high-cost capital itemssuch as our Niobe ES system, Odyssey Solution, or Vdrive system. In many cases, a limited number of these certificates are available. As a result of thislimited availability, hospitals and other health care providers may be unable to obtain a certificate of need for the purchase of our systems. Further, our salesand installation cycle for the Niobe ES system is typically longer in certificate of need states due to the time it takes our customers to obtain the requiredapprovals. In addition, our customers must meet various federal and state regulatory and/or accreditation requirements in order to receive payments fromgovernment-sponsored health care programs such as Medicare and Medicaid, receive full reimbursement from third party payors, and maintain theircustomers. Our international customers may be required to meet similar or other requirements. Any lapse by our customers in maintaining appropriatelicensure, certification or accreditation, or the failure of our customers to satisfy the other necessary requirements under government-sponsored health careprograms or other requirements could cause our sales to decline.Hospitals or physicians may be unable to obtain reimbursement from third-party payors for procedures using the Niobe or Vdrive systems, orreimbursement for procedures may be insufficient to recoup the costs of purchasing our products.We expect that U.S. hospitals will continue to bill various third-party payors, such as Medicare, Medicaid and other government programs and privateinsurance plans, for procedures performed with our products, including the costs of the disposable interventional devices used in these procedures. If in thefuture our disposable interventional devices do not fall within U.S. reimbursement categories and our procedures are not reimbursed, or if the reimbursementis insufficient to cover the costs of purchasing our system and related disposable interventional devices, the adoption of our systems and products would besignificantly slowed or halted, and we may be unable to generate sufficient sales to support our business. Our success in international markets also dependsupon the eligibility of our products for reimbursement through government-sponsored 35health care payment systems and third-party payors. In both the U.S. and foreign markets, health care cost-containment efforts are prevalent and are expectedto continue. These efforts could reduce levels of reimbursement available for procedures involving our products and, therefore, reduce overall demand for ourproducts as well. A failure to generate sufficient sales could have a material adverse impact on our financial condition, results of operations and cash flow.Our growth will place a significant strain on our resources, and if we fail to manage our growth, our ability to develop, market, and sell ourproducts will be harmed.Our business plan contemplates a period of substantial growth and business activity. This growth and activity will likely result in new and increasedresponsibilities for management personnel and place significant strain upon our operating and financial systems and resources. To accommodate our growthand compete effectively, we will be required to improve our information systems, create additional procedures and controls and expand, train, motivate andmanage our work force. We cannot be certain that our personnel, systems, procedures, and controls will be adequate to support our future operations. Anyfailure to effectively manage our growth could impede our ability to successfully develop market and sell our products.We face currency and other risks associated with international operations.We intend to continue to devote significant efforts to marketing our systems and products outside of the U.S. This strategy will expose us to numerousrisks associated with international operations, which could adversely affect our results of operations and financial condition, including the following: • currency fluctuations that could impact the demand for our products or result in currency exchange losses; • export restrictions, tariff and trade regulations and foreign tax laws; • customs duties, export quotas or other trade restrictions; • economic and political instability; and • shipping delays.In addition, contracts may be difficult to enforce and receivables difficult to collect through a foreign country’s legal system.Our continuing ability to use Form S-3 may be limited.As of the date of the filing of this Form 10-K, our public float is slightly above $75 million. As a result, any reduction in our market capitalizationcould limit our ability to file new shelf registration statements on SEC Form S-3 and/or to fully use the remaining capacity on our existing registrationstatements on SEC Form S-3. We have relied significantly on shelf registration statements on SEC Form S-3 for many of our financings in recent years, soany such limitations may harm our ability to raise the capital we need. In addition, if we are unable to remain compliant with our bank financing covenants,or if we are not able to timely file and make effective registration statements prior to the dates required under the federal securities laws, we would be ineligibleto use Form S-3 for a 12-month period. Under those circumstances, until we are again eligible to use Form S-3, we would be required to use a registrationstatement on Form S-1 to register securities with the SEC or issue such securities in a private placement, which could increase the cost of raising capital. 36Risks Related To Our Common StockOur principal stockholders continue to own a large percentage of our voting stock, and they have the ability to substantially influence mattersrequiring stockholder approval.Certain of our directors and individuals or entities affiliated with them as well as other principal stockholders beneficially own or control a substantialpercentage of the outstanding shares of our common stock. Moreover, as a result of the issuance of warrants to certain institutional investors, certain of ourdirectors and their affiliated funds have the ability to obtain a substantial portion of our common stock. Accordingly, these stockholders acting as a group,will have substantial influence over the outcome of corporate actions requiring stockholder approval, including the election of directors, any merger,consolidation or sale of all or substantially all of our assets or any other significant corporate transaction. These stockholders may also delay or prevent achange of control, even if such a change of control would benefit our other stockholders. This significant concentration of stock ownership may adverselyaffect the trading price of our common stock due to investors’ perception that conflicts of interest may exist or arise.Future issuances of our securities could dilute current stockholders’ ownership.We have outstanding warrants to purchase 3.0 million shares of the Company’s common stock at a weighted average exercise price of $14.21, withprices ranging from $1.55 to $46.40. A significant number of shares of our common stock are subject to stock options and stock appreciation rights, and wemay request the ability to issue additional such securities to our employees. We may also decide to raise additional funds through public or private debt orequity financing to fund our operations. While we cannot predict the effect, if any, that future exercises of warrants or future sales of debt, our common stock,other equity securities or securities convertible into our common stock or other equity securities or the availability of any of the foregoing for future sale, willhave on the market price of our common stock, it is likely that sales of substantial amounts of our common stock (including shares issued upon the exerciseof warrants, stock options, stock appreciation rights or the conversion of any convertible securities outstanding now or in the future), or the perception thatsuch sales could occur, will adversely affect prevailing market prices for our common stock.We have never paid dividends on our capital stock, and we do not anticipate paying any cash dividends in the foreseeable future.We have paid no cash dividends on any of our classes of capital stock to date and we currently intend to retain our future earnings to fund thedevelopment and growth of our business. In addition, the terms of our loan agreement prohibit us from declaring dividends without the prior consent of ourlender. As a result, capital appreciation, if any, of our common stock will be an investor’s sole source of gain for the foreseeable future.Our certificate of incorporation and bylaws, Delaware law and one of our alliance agreements contain provisions that could discourage atakeover.Our certificate of incorporation and bylaws and Delaware law contain provisions that might enable our management to resist a takeover. Theseprovisions may: • discourage, delay or prevent a change in the control of our company or a change in our management; • adversely affect the voting power of holders of common stock; and • limit the price that investors might be willing to pay in the future for shares of our common stock.In addition, our alliance agreement with Biosense Webster and our debt agreement with Healthcare Royalty Partners II, L.P. contain provisions that maysimilarly discourage a takeover and negatively affect our share price as described above. 37Evolving regulation of corporate governance and public disclosure may result in additional expenses and continuing uncertainty.Changing laws, regulations and standards relating to corporate governance and public disclosure, including the new SEC regulations such as the Dodd-Frank Wall Street Reform and Consumer Protection Act, and NASDAQ Capital Market rules have in the past created uncertainty for public companies. Wecontinue to evaluate and monitor developments with respect to new and proposed rules and cannot predict or estimate the amount of the additional compliancecosts we may incur or the timing of such costs. These new or changed laws, regulations and standards are subject to varying interpretations, in many casesdue to their lack of specificity, and as a result, their application in practice may evolve over time as new guidance is provided by courts and regulatory andgoverning bodies. This could result in uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure andgovernance practices. Maintaining appropriate standards of corporate governance and public disclosure may result in increased general and administrativeexpense and a diversion of management time and attention from revenue-generating activities to compliance activities. In addition, if we fail to comply with newor changed laws, regulations and standards, regulatory authorities may initiate legal proceedings against us and our business and reputation may be harmed.Our future operating results may be below securities analysts’ or investors’ expectations, which could cause our stock price to decline.The revenue and income potential of our products and our business model are unproven, and we may be unable to generate significant revenue or growat the rate expected by securities analysts or investors. In addition, our costs may be higher than we, securities analysts, or investors expect. If we fail togenerate sufficient revenue or our costs are higher than we expect, our results of operations will suffer, which in turn could cause our stock price to decline.Our results of operations will depend upon numerous factors, including: • demand for our products; • the performance of third-party contract manufacturers and component suppliers; • our ability to develop sales and marketing capabilities; • the success of our collaborations with Siemens, Philips and Biosense Webster and others; • our ability to develop, introduce and market new or enhanced versions of our products on a timely basis; • our ability to obtain regulatory clearances or approvals for our new products; and • our ability to obtain and protect proprietary rights.Our operating results in any particular period may not be a reliable indication of our future performance. In some future quarters, our operating resultsmay be below the expectations of securities analysts or investors. If this occurs the price of our common stock will likely decline.We expect that the price of our common stock could fluctuate substantially, possibly resulting in class action securities litigation.Our common stock is traded on the NASDAQ Capital Market and trading volume may be limited or sporadic. The market price of our common stockhas experienced, and may continue to experience, substantial volatility. During 2013, our common stock traded between $1.21 and $10.85 per share, ontrading volume ranging from approximately 4,500 to 21 million shares per day. The market price of our common stock will be affected by a number offactors, including: • actual or anticipated variations in our results of operations or those of our competitors; • the receipt or denial of regulatory approvals; 38 • announcements of new products, technological innovations or product advancements by us or our competitors; • developments with respect to patents and other intellectual property rights; • changes in earnings estimates or recommendations by securities analysts or our failure to achieve analyst earnings estimates; • developments in our industry; and • participants in the market for our common stock may take short positions with respect to our common stock.These factors, as well as general economic, credit, political and market conditions, may materially adversely affect the market price of our commonstock. As with the stock of many other public companies, the market price of our common stock has been particularly volatile during the recent period ofupheaval in the capital markets and world economy. This excessive volatility may continue for an extended period of time following the filing date of thisreport. Furthermore, the stock prices of many companies in the medical device industry have experienced wide fluctuations that have often been unrelated tothe operating performance of these companies. Volatility in the price of our common stock on the NASDAQ Capital Market may depress the trading price ofour common stock, which could, among other things, allow a potential acquirer of the Company to purchase a significant amount of our common stock atlow prices.We and certain of our current and former executive officers and directors, are defendants in a federal securities class action lawsuit and a federalshareholder derivative lawsuit. These lawsuits are described in Part I Item 3 “Legal Proceedings” in this Annual Report on Form 10-K. Our attention may bediverted from our ordinary business operations by these lawsuits and we may incur significant expenses associated with the defense of these lawsuits(including substantial fees of lawyers and other professional advisors and potential obligations to indemnify officers and directors and our underwriters whomay be parties to such action). Depending on the outcome of these lawsuits, we may be required to pay material damages and fines, consent to injunctions onfuture conduct, or suffer other penalties, remedies or sanctions. The ultimate resolution of these matters could have a material adverse effect on our results ofoperations, financial condition, liquidity, our ability to meet our debt obligations and, consequently, negatively impact the trading price of our common stock.In addition, the volatility of our stock price could lead to similar class action securities litigation being filed against us in the future, which could result insubstantial costs and a diversion of our management resources, which could significantly harm our business. ITEM 1B.UNRESOLVED STAFF COMMENTSWe have not received any written comments regarding our periodic or current reports from the staff of the SEC that were issued 180 days or morepreceding the end of our 2013 fiscal year and that remain unresolved. ITEM 2.PROPERTIESOur primary company facilities are located in St. Louis, Missouri where we currently lease approximately 52,000 square feet of office and 12,000square feet of demonstration and assembly space. In the third quarter of 2013, the Company modified the existing lease agreement to terminate approximately13,000 square feet of unimproved space. This space is leased under an agreement through 2018.We lease approximately 3,900 square feet of office space in Maple Grove, Minnesota, under a lease agreement through October 31, 2014, and have leasedoffice space in Amsterdam, The Netherlands through August 31, 2014. In addition, we lease an office space in Beijing, China on a month by month basis. 39ITEM 3.LEGAL PROCEEDINGSOn October 7, 2011, a purported securities class action was filed against the Company and two of the Company’s past executive officers in the U.S.District Court for the Eastern District of Missouri by Kevin Pound, a purported shareholder of the Company. On December 29, 2011, the court granted anunopposed motion appointing Local 522 Pension Fund as Lead Plaintiff in the action and granting Lead Plaintiff leave to file an Amended Complaint, whichLead Plaintiff filed on March 19, 2012. The Amended Complaint alleges that, during the period from February 28, 2011 through August 9, 2011, theCompany and certain of its officers made materially false and misleading statements regarding the Company’s financial condition and future businessprospects, in violation of sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended. The Amended Complaint seeks unspecified damages,costs, attorneys’ fees and such other relief as the Court may deem appropriate. On May 18, 2012, the Company filed a motion to dismiss the AmendedComplaint. On July 24, 2012, Lead Plaintiff filed its response to the motion to dismiss, and on August 30, 2012, the Company filed its reply brief in supportof the motion to dismiss. On March 18, 2014, the Court granted the Company’s motion to dismiss and entered judgment in favor of the defendants andagainst the plaintiffs. The plaintiffs have thirty days, or until April 17, 2014, to file a notice of appeal. The Company believes the complaint is without meritand, in the event of an appeal by the plaintiffs, intends to vigorously defend against it. In addition, the Company has obligations, under certaincircumstances, to indemnify the individual defendants with respect to claims asserted against them and otherwise to the fullest extent permitted under Delawarelaw and the Company’s bylaws and certificate of incorporation.On December 2, 2011, a purported shareholder derivative action was filed in the U.S. District Court for the Eastern District of Missouri by Carl Zorn,a purported shareholder of the Company, against the directors of the Company and the Company as a nominal defendant. The Complaint in this action allegesthat the individual defendants breached their fiduciary duties to the Company, engaged in gross mismanagement and caused waste of corporate assets of theCompany by allowing the Company and certain of its officers to make the same allegedly false and misleading statements regarding the Company’s financialcondition and future business prospects that are at issue in the purported class action. The Complaint seeks unspecified damages, restitution and otherequitable relief, as well as costs and attorneys’ fees from the named defendants on behalf of the Company. At the request of all parties, on March 22, 2012,the Court entered an order staying the case pending resolution of the motion to dismiss in the securities class action. The Company believes the complaint iswithout merit and intends to vigorously defend against it. However, litigation is inherently uncertain and it is too early in this proceeding to predict the outcomeof this lawsuit or to reasonably estimate possible losses, if any, related thereto. In addition, the Company has obligations, under certain circumstances, toindemnify the individual defendants with respect to claims asserted against them and otherwise to the fullest extent permitted under Delaware law and theCompany’s bylaws and certificate of incorporation.Additionally, we are involved from time to time in various lawsuits and claims arising in the normal course of business. Although the outcomes of theselawsuits and claims are uncertain, we do not believe any of them will have a material adverse effect on our business, financial condition or results ofoperations.

The Epoch Solution is comprised of the Niobe ES roboticsystem, Odyssey Solution, and the Vdrive system. We believe that the Epoch Solution represents a revolutionary technology in the interventional surgicalsuite, or “interventional lab”, and has the potential to become the standard of care for a broad range of complex cardiology procedures. We also believe that ourtechnology represents an important advance in the ongoing trend toward digital instrumentation in the interventional lab and provides substantial, clinicallyimportant improvements and cost efficiencies over manual interventional methods, which require years of physician training and often result in long andunpredictable procedure times and sub-optimal therapeutic outcomes.The Niobe ES robotic system is the latest generation of the Niobe Robotic Magnetic Navigation System (“Niobe system”). This system is designed toenable physicians to complete more complex interventional procedures by providing image guided delivery of catheters and guidewires through the bloodvessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern the motion of the working tip of thecatheter or guidewire, resulting in improved navigation, efficient procedures and reduced x-ray exposure. The core components of the Niobe system havereceived regulatory clearance in the U.S., Canada, Europe, China, Japan and various other countries.Stereotaxis also has developed the Odyssey Solution which consolidates all lab information enabling doctors to focus on the patient for optimalprocedure efficiency. The system also features a remote viewing and recording capability called Odyssey Cinema, which is an innovative solution deliveringsynchronized content for optimized workflow, advanced care and improved productivity. This tool includes an archiving capability that allows clinicians tostore and replay entire procedures or segments of procedures. This information can be accessed from locations throughout the hospital local area network andover the global Odyssey Network providing physicians with a tool for clinical collaboration, remote consultation and training. The Odyssey Solution may beacquired in conjunction with a Niobe system or on a stand-alone basis for installation in interventional labs and other locations where clinicians often desirethe benefits of Odyssey Solution that we believe can improve clinical workflows and related efficiencies. 44Our Vdrive system provides navigation and stability for diagnostic and therapeutic devices designed to improve interventional procedures. The Vdrivesystem complements the Niobe ES system control of therapeutic catheters for fully remote procedures and enables single-operator workflow and is sold as twooptions, the Vdrive system and the Vdrive Duo system. In addition to the Vdrive system and the Vdrive Duo system, we also manufacture and marketvarious disposable components (V-Loop, V-Sono, V-CAS, and V-CAS Deflect) which can be manipulated by these systems.We generate revenue from both the initial capital sales of the Niobe, Odyssey and Vdrive systems as well as recurring revenue from the sale of ourproprietary disposable devices, from ongoing license and service contracts, and from royalties paid to the Company on the sale by Biosense Webster of co-developed catheters. We market our products to a broad base of hospitals in the United States and internationally as detailed in Note 18 to the financialstatements.We have alliances with each of Siemens AG Medical Solutions, Philips Medical Systems and Biosense Webster, Inc., through which we integrate ourNiobe system with market leading digital imaging and 3D catheter location sensing technology, as well as disposable interventional devices, in order tocontinue to develop new solutions in the interventional lab. Each of these alliances provides for coordination of our sales and marketing activities with those ofour partners.Since our inception, we have generated significant losses. As of December 31, 2013, we had incurred cumulative net losses of approximately $453.4million. As of December 31, 2013, the Company had an installed base of 100 Niobe ES systems and has received positive feedback from the physicians atthese sites. We expect to incur additional losses and to have negative cash flow from operations into 2014 as we continue the development andcommercialization of our products, conduct our research and development activities and advance new products into clinical development from our existingresearch programs and fund additional sales and marketing initiatives. Our existing cash, cash equivalents and borrowing facilities may not be sufficient tofund our operating expenses and capital equipment requirements through the next 12 months, which would require us to obtain additional financing before thattime.The Company’s independent registered public accounting firm’s report issued in this Annual Report on Form 10-K included an explanatory paragraphdescribing the existence of conditions that raise substantial doubt about the Company’s ability to continue as a going concern, including recurring operatinglosses and the net capital deficiency. The financial statements do not include any adjustments relating to the recoverability and classification of assets carryingamounts or the amount of and classification of liabilities that may result should the Company be unable to continue as a going concern.Critical Accounting Policies and EstimatesOur discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared inaccordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments thataffect the reported amounts of assets, liabilities, revenue and expenses and related disclosures. We review our estimates and judgments on an on-going basis.We base our estimates and judgments on historical experience and on various other assumptions that we believe to be reasonable under the circumstances.Actual results may differ from these estimates. We believe the following accounting policies are critical to the judgments and estimates we use in preparing ourfinancial statements.Revenue RecognitionThe Company adopted Accounting Standards Update 2009-13, Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”) in the fourth quarterof 2009, effective as of January 1, 2009.ASU 2009-13 permits management to estimate the selling price of undelivered components of a bundled sale for which it is unable to establish vendor-specific objective evidence (“VSOE”) or third-party evidence 45(“TPE”). This requires management to record revenue for certain elements of a transaction even though it might not have delivered other elements of thetransaction, for which it was unable to meet the requirements for establishing VSOE or TPE. The Company believes that the guidance significantly improvesthe reporting of these types of transactions to more closely reflect the underlying economic circumstances. This guidance also prohibits the use of the residualmethod for allocating revenue to the various elements of a transaction and requires that the revenue be allocated proportionally based on the relative estimatedselling prices.Under our revenue recognition policy, a portion of revenue for Niobe systems, Vdrive systems and certain types of Odyssey systems is recognized upondelivery, provided that title has passed, there are no uncertainties regarding acceptance, persuasive evidence of an arrangement exists, the sales price is fixedand determinable, and collection of the related receivable is reasonably assured. Revenue is recognized for other types of Odyssey systems upon completion ofinstallation, since there are no qualified third party installers. When installation is the responsibility of the customer, revenue from system sales is recognizedupon shipment since these arrangements do not include an installation element or right of return privileges. We do not recognize revenue in situations in whichinventory remains at a Stereotaxis warehouse or in situations in which title and risk of loss have not transferred to the customer. However, we may deliversystems to a non-hospital site at the customer’s request as outlined in the terms and conditions of the sales agreement, in which case we evaluate whether thesubstance of the transaction meets the delivery and performance requirements for revenue recognition under “bill and hold” guidance. Amounts collected priorto satisfying the above revenue recognition criteria are reflected as deferred revenue. Revenue from services and license fees, whether sold individually or as aseparate unit of accounting in a multi-element arrangement, is deferred and amortized over the service or license fee period, which is typically one year. Revenuefrom services is derived primarily from the sale of annual product maintenance plans. We recognize revenue from disposable device sales or accessories uponshipment and establish an appropriate reserve for returns. The return reserve, which is applicable only to disposable devices, is estimated based on historicalexperience which is periodically reviewed and updated as necessary. In the past, changes in estimate have had only a de minimus effect on revenue recognizedin the period. We believe that the estimate is not likely to change significantly in the future.Stock-based CompensationStock compensation expense, which is a non-cash charge, results from stock option and stock appreciation rights grants made to employees, anddirectors at the fair value of the option granted, and from grants of restricted shares and units to employees, directors, and third-party consultants. The fairvalue of options and stock appreciation rights granted was determined using the Black-Scholes valuation method which gives consideration to the estimatedvalue of the underlying stock at the date of grant, the exercise price of the option, the expected dividend yield and volatility of the underlying stock, theexpected life of the option and the corresponding risk-free interest rate. The fair value of the grants of restricted shares and units was determined based on theclosing price of our stock on the date of grant. Stock compensation expense for options, stock appreciation rights and for time-based restricted share grants isamortized on a straight-line basis over the vesting period of the underlying issue, generally over four years except for grants to directors which generally vestover one to two years and restricted stock units which generally vest over a period of 18 months to four years. Stock compensation expense for performance-based restricted shares is amortized on a straight-line basis over the anticipated vesting period and is subject to adjustment based on the actual achievement ofobjectives. Compensation expenses related to option grants to non-employees are re-measured quarterly through the vesting date. Compensation expense isrecognized only for those options expected to vest, net of estimated forfeitures. Estimates of the expected life of options have been based on the average of thevesting and expiration periods, which is the simplified method under general accounting principles for share-based payments. Estimates of volatility andforfeiture rates utilized in calculating stock-based compensation have been prepared based on historical data and future expectations. Actual experience to datehas been consistent with these estimates.The amount of compensation expense to be recorded in future periods may increase if we make additional grants of options, stock appreciation rights orrestricted shares or if we determine that actual forfeiture rates are 46less than anticipated. The amount of expense to be recorded in future periods may decrease if the requisite service periods are not completed or if the actualforfeiture rates are greater than anticipated.Valuation of InventoryWe value our inventory at the lower of the actual cost of our inventory, as determined using the first-in, first-out (FIFO) method, or its current estimatedmarket value. We periodically review our physical inventory for excess, obsolete, and potentially impaired items and reserve accordingly. Our reserve estimatefor excess and obsolete is based on expected future use. Our reserve estimates have historically been consistent with our actual experience as evidenced byactual sale or disposal of the goods.Deferred Income TaxesDeferred assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using theenacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary toreduce deferred tax assets to the amounts expected to be realized. We have established a valuation allowance against the entire amount of our deferred tax assetsbecause we are not able to conclude, due to our history of operating losses, that it is more likely than not that we will be able to realize any portion of thedeferred tax assets.In assessing whether and to what extent deferred tax assets are realizable, we consider whether it is more likely than not that some portion or all of thedeferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during theperiods in which those temporary differences become deductible. We consider projected future taxable income and tax planning strategies in making thisassessment. Based upon the level of historical taxable losses, limitations imposed by Section 382 of the Internal Revenue Code and projections for future lossesover periods which the deferred tax assets are deductible, we determined that a 100% valuation allowance of deferred tax assets was appropriate.Results of OperationsComparison of the Years ended December 31, 2013 and 2012Revenue. Revenue decreased to $38.0 million for the year ended December 31, 2013, from $46.6 million for the year ended December 31, 2012, adecrease of approximately 18%. Revenue from sales of systems decreased to $12.7 million for the year ended December 31, 2013, from $19.7 million for theyear ended December 31, 2012, a decrease of approximately 35%. We recognized revenue on nine Niobe ES systems, a total of $0.9 million for Niobe ESupgrades, $3.7 million for Odyssey and Odyssey Cinema systems, and a total of $0.3 million for Vdrive systems during the 2013 reporting period comparedto nine Niobe systems, and a total of $3.3 million for Niobe ES upgrades, $6.5 million for Odyssey and Odyssey Cinema systems, and $1.1 million forVdrive systems during the 2012 reporting period. Revenue from sales of disposable interventional devices, service and accessories decreased to $25.3 millionfor the year ended December 31, 2013, from $26.9 million for the year ended December 31, 2012, a decrease of approximately 6%. The decrease wasattributable to lower disposable sales volume as a result of lower utilization.Cost of Revenue. Cost of revenue decreased to $11.0 million for the year ended December 31, 2013, from $14.8 million for the year ended December 31,2012, a decrease of approximately 26%. As a percentage of our total revenue, overall gross margin increased from 68% for the year ended December 31, 2012,to 71% for the year ended December 31, 2013, due to a shift in mix from system revenue to disposable, service, and accessories revenue. Cost of revenue forsystems sold decreased to $6.9 million for the year ended December 31, 2013, from $9.9 million for the year ended December 31, 2012, a decrease ofapproximately 31%. This decrease was primarily due to decreased system sales volumes across Odyssey, Odyssey Cinema and Vdrive product lines. Grossmargin for systems was 46% for the year ended December 31, 2013, compared to 50% for year ended December 31, 2012. The decrease is primarilyattributable to lower production volumes and related cost 47absorption as well as lower gross margin on Niobe ES systems. Cost of revenue for disposable interventional devices, service and accessories decreased to$4.1 million for the year ended December 31, 2013, from $4.9 million for the year ended December 31, 2012, resulting in an increase in gross margin to 84%from 82% between these periods. The increase is due to higher margins on service in the current year period due to fewer ES upgrades provided in exchange forextended service contracts.Research and Development Expense. Research and development expense decreased to $5.7 million for the year ended December 31, 2013 from $8.4million for the year ended December 31, 2012, a decrease of approximately 33%. The decrease is primarily due to reduced headcount expenses and a reductionin consulting, contract research, and material expenses as part of the Company’s efforts to reduce operating expenses.Sales and Marketing Expense. Sales and marketing expense decreased to $17.1 million for the year ended December 31, 2013, from $20.6 million forthe year ended December 31, 2012, a decrease of approximately 17%. The decrease was due to primarily due to reduced headcount and related travel expensesas well as decreased marketing and consulting expenses.General and Administrative Expense. General and administrative expenses include regulatory, clinical, general management and training expenses.General and administrative expense decreased to $13.1 million for the year ended December 31, 2013, from $13.4 million for the year ended December 31,2012, a decrease of approximately 2%. The decrease was primarily due to reduced headcount, partially offset by increased consulting expenses, lease exitactivities and medical device excise tax.Other Income (Expense). Other expense represents the non-cash change in market value of certain warrants classified as a derivative and recorded as acurrent liability under general accounting principles for determining whether an instrument (or embedded feature) is indexed to an entity’s own stock. Otherexpense also includes the adjustment in fair value of the derivative asset and liability related to the conversion features embedded in the subordinatedconvertible debentures. Other expense increased to $47.3 million for the year ended December 31, 2013, due primarily to the adjustment of warrants andconvertible debt features in connection with the third quarter capital transactions with convertible note holders and other equity investors.Interest Expense. Interest expense increased to $12.6 million for the year ended December 31, 2013 from $6.9 million for the year ended December 31,2012, due primarily to the write-off of the unamortized debt discount in connection with the third quarter capital transactions with convertible note holders andother equity investors.Comparison of the Years ended December 31, 2012 and 2011Revenue. Revenue increased to $46.6 million for the year ended December 31, 2012 from $42.0 million for the year ended December 31, 2011, anincrease of approximately 11%. Revenue from sales of systems increased to $19.7 million for the year ended December 31, 2012 from $15.6 million for theyear ended December 31, 2011, an increase of approximately 26%, primarily due to an increase in the number of Niobe systems and Niobe ES upgradessold. The number of units recognized to revenue was 9 Niobe systems and a total of $3.3 million for Niobe ES upgrades and $6.5 million for Odysseysystems during the 2012 reporting period compared to 7 Niobe systems, and a total of $0.5 million for Niobe ES upgrades and $7.4 million for Odysseysystems during the 2011 reporting period. Revenue from sales of disposable interventional devices, service and accessories increased to $26.9 million for theyear ended December 31, 2012 from $26.4 million for the year ended December 31, 2011, an increase of approximately 2%. The increase was attributable toimproved utilization due to Niobe ES upgrades and to a lesser extent the increased base of installed systems, the resulting disposable sales, offset by lowerroyalty income resulting from a reduction in the royalty rate effective January 1, 2012.Cost of Revenue. Cost of revenue increased to $14.8 million for the year ended December 31, 2012 from $12.5 million for the year ended December 31,2011, an increase of approximately 18%. As a percentage of our 48total revenue, overall gross margin decreased from 70% for the year ended December 31, 2011, to 68% for the year ended December 31, 2012, due to a shift inmix from disposable, service, and accessories revenue to systems revenue. Cost of revenue for systems sold increased to $9.9 million for the year endedDecember 31, 2012 from $8.6 million for the year ended December 31, 2011, an increase of approximately 15%. This increase was primarily due to anincrease in the number of Niobe units sold in 2012 compared to 2011. Gross margin for systems was 50% for the year ended December 31, 2012, comparedto 45% for year ended December 31, 2011. The improvement is primarily attributable to higher production volumes and related cost absorption. Cost ofrevenue for disposable interventional devices, service and accessories increased to $4.9 million for the year ended December 31, 2012 from $3.9 million forthe year ended December 31, 2011, resulting in a decrease in gross margin to 82% from 85% between these periods. The decrease in gross margin is due to ahigher mix of lower margin disposables revenue, lower royalties and providing Niobe ES upgrades in exchange for new or extended premium service contractsResearch and Development Expense. Research and development expense decreased to $8.4 million for the year ended December 31, 2012 from $12.9million for the year ended December 31, 2011, a decrease of approximately 35%. The decrease is primarily due to the completion of major development effortsof the Epoch Solution and Odyssey system upgrades in 2011, as well as reduced headcount expenses.Sales and Marketing Expense. Sales and marketing expense decreased to $20.6 million for the year ended December 31, 2012, from $31.6 million forthe year ended December 31, 2011, a decrease of approximately 35%. The decrease was due to primarily due to reduced headcount and related travel andrelocation expenses as well as lower marketing and consulting expenses.General and Administrative Expense. General and administrative expenses include regulatory, clinical, general management and training expenses.General and administrative expense decreased to $13.4 million for the year ended December 31, 2012, from $16.9 million for the year ended December 31,2011, a decrease of approximately 21%. The decrease was primarily due to reduced headcount and related travel and relocation expenses, lower spending onregistrations in Japan as our products approach the end of clinical trials, and decreased bad debt expense and consulting costs.Other Income. Other income increased to $8.3 million for the year ended December 31, 2012 from $3.4 million for the year ended December 31, 2011.Other income represents the change in market value of certain warrants classified as a derivative and recorded as a current liability under general accountingprinciples for determining whether an instrument (or embedded feature) is indexed to an entity’s own stock. Other income also includes the adjustment in fairvalue of the derivative asset and liability related to the conversion features embedded in the subordinated convertible debentures. The primary drivers offluctuations in this balance are changes in the Company’s stock price from one period to the next.Interest Expense. Interest expense increased to $6.9 million for the year ended December 31, 2012 from $3.5 million for the year ended December 31,2011, due to the Healthcare Royalty Partners II, L.P. (formerly “Cowen Healthcare Royalty Partners II, L.P.”) financing in November 2011 and additional$2.5 million borrowing in August 2012, and the issuance of $8.5 million in Debentures in May 2012. Interest expense also includes the amortization of thedebt discount on the Debentures totaling $1.0 million for the year ended December 31, 2012.Income TaxesRealization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain. Accordingly, net deferred tax assetshave been fully offset by valuation allowances as of December 31, 2013, 2012 and 2011 to reflect these uncertainties. As of December 31, 2013, we hadfederal net operating loss carryforwards of approximately $75.8 million which will expire between 2018 and 2033. As of December 31, 2013, we had state netoperating loss carryforwards of approximately $2.3 million which will expire at various dates between 2014 and 2033 if not utilized. We may not be able toutilize all of these loss carryforwards prior to their expiration. 49Capital ResourcesAs of December 31, 2013, our borrowing facilities were comprised of a revolving line of credit with $3.0 million of unborrowed availability with ourprimary lender, Silicon Valley Bank, as well as the Healthcare Royalty Partners debt discussed in the following sections.Biosense Webster AdvanceIn July 2008, the Company and Biosense Webster entered into an amendment to their existing agreements relating to the development and sale ofcatheters. Pursuant to the amendment, Biosense Webster agreed to pay to the Company $10.0 million as an advance on royalty amounts that were owed at thetime the amendment was executed or would be owed in the future by Biosense Webster to the Company pursuant to the royalty provisions of one of the existingagreements.

Interest onthe outstanding and unrecouped amounts of the royalty advance and deferred research and development expenses accrued at an interest rate of the prime rateplus 0.75%. Outstanding royalty advances and deferred research and development expenses and accrued interest thereon were recouped by Biosense Websterby deductions from royalty amounts otherwise owed to the Company from Biosense Webster pursuant to the existing agreement. Approximately $18.0 millionhad been advanced by Biosense Webster to the Company pursuant to the amendment.

Thewarrants are exercisable at $40.15 per share, beginning on March 1, 2011 and expiring on February 28, 2016. The fair value of these warrants of$1,747,392, calculated using the Black-Scholes method, will be deferred and amortized to interest expense ratably. As the previous guarantee was no longer ineffect, the Company expensed in 2010 the entire balance on the warrants issued to the Lenders in October 2009.In December 2010, the Company further amended its agreement with its primary lender to extend the maturity of the current working capital line ofcredit from March 31, 2011 to March 31, 2012, retaining the $30 million total availability under the line per the 2009 amendment.

The use of paymentsdue to the Company under the Biosense Agreement was approved by our primary lender under the Amended Loan Agreement described above.Subordinated Convertible DebenturesIn May 2012, the Company entered into a securities purchase agreement with certain institutional investors whereby the Company agreed to sell anaggregate of approximately $8.5 million in aggregate principal amount of unsecured, subordinated, convertible debentures (the “Debentures”), which becameconvertible into shares of the Company’s common stock at a conversion price of $3.361 per share (or approximately 2.5 million shares in the aggregate), onJuly 10, 2012, the date that the Company received shareholder approval for the transaction. The purchasers of the Debentures also received warrants, whichwere scheduled to expire in November 2018, to purchase an aggregate of approximately 2.5 million shares of the Company’s common stock at an exerciseprice of $3.361 per share (“Convert Warrants”). The Debentures bear interest at 8% per year and were scheduled to mature on May 7, 2014. In addition, theCompany had the ability to issue shares of its common stock in lieu of cash interest payments under certain circumstances, and following the registration ofthe shares for resale, the Company issued shares in lieu of cash interest payments. 52The Company recorded the Debentures on the balance sheet net of the debt discount. The debt discount of $7.6 million was due to warrants issued inconjunction with the Debentures and the debt conversion features. Upon issuance of the Debentures, the fair value of the warrants and derivative liability were$4.1 million and $3.5 million, respectively. The debt discount was amortized over the life of the loan using the effective interest method and the warrants andderivative liability were recorded at fair value on each reporting period. Refer to Note 12 for additional discussion of the fair value of the warrants andconversion features.On August 7, 2013, holders of Convert Warrants exercised all of their Convert Warrants for an aggregate of approximately $2.5 million shares of ourcommon stock, resulting in cash proceeds of approximately $8.5 million. In addition, holders of all of the Debentures exchanged the balance of theirunconverted Debentures for an aggregate of approximately 2.7 million shares of the Company’s common stock and additional warrants (the “ExchangeWarrants”) to purchase approximately 2.5 million shares, having an exercise price of $3.361 per share. On August 8, 2013, certain former holders of theDebentures exercised Exchange Warrants to purchase an aggregate of 1.4 million shares of common stock in cashless net exercises as provided for in theExchange Warrants, which resulted in the issuance to such funds of an aggregate of 0.8 million shares of common stock, but no net proceeds to the Company.The Company is relying on the exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended, based on representations tothe Company made by the warrant holders.The mark-to-market expense associated with the adjustment of warrants and convertible debt features in connection with the third quarter capitaltransactions are included in other expense for the year ended December 31, 2013. The write-off of the unamortized debt discount is included in interest expensefor the year ended December 31, 2013.Listing Transfer to NASDAQ Capital MarketOn August 15, 2013, the NASDAQ Listing Qualifications Panel (the “Panel”) granted approval of the Company’s request to transfer its listing to TheNASDAQ Capital Market from The NASDAQ Global Market.

The Reverse Stock Split affected all issued and outstanding shares of the Company’scommon stock, as well as common stock underlying stock options, stock appreciation rights, restricted stock, restricted stock units, warrants andconvertible debentures outstanding immediately prior to the effectiveness of the Reverse Stock Split. The Reverse Stock Split reduced the number of shares ofthe Company’s common stock outstanding from approximately 78 million to 7.8 million at the time of the Reverse Stock Split. In addition, the Amendmentincreased the number of authorized shares of the Company’s common stock from 100 million to 300 million. The Reverse Stock Split did not alter the parvalue of common stock, which remained $0.001 per share, or modify any voting rights or other terms of the Company’s common stock.

We used approximately $6.3 million, $12.1 million, and $31.6 million of cash in operating activities during theyears ended December 31, 2013, 2012, and 2011, respectively. The decrease in cash used in operating activities from December 31, 2011, to December 31,2013, is primarily a result of reduction in operating losses from 2011 to 2012 and changes in working capital from 2012 to 2013. 54Net cash used in investing activities. There were no purchases of equipment during the year ended December 31, 2013. We used approximately $0.1million and $1.0 million to fund investing activities during the years ended December 31, 2012, and 2011, respectively, for the purchase of property andequipment.Net cash provided by financing activities. We generated approximately $12.3 million from financing activities during the year ended December 31,2013 compared to $6.1 million generated for the year ended December 31, 2012 and $11.3 million generated for the year ended December 31, 2011. Theincrease in cash generated from 2012 to 2013 was primarily driven by increased stock transactions, including warrant exercises, of $12.2 million comparedto 2012 offset by reduced debt financing of $5.9 million in 2013 compared to 2012. The decrease from 2011 to 2012 cash generated was primarily due to$7.7 million from the issuance of subordinated convertible debentures and warrants, $9.1 million from stock and warrants and $2.5 million in additionalborrowing from Healthcare Royalty Partners partially offset by $8.0 million net payments under our revolving line of credit, $4.0 million related to the termnote, and $1.3 million for the Healthcare Royalty Partners debt.At December 31, 2013, we had working capital of approximately $4.4 million, compared to a working capital deficit of $5.7 million at December 31,2012.As of December 31, 2013, the Company had no outstanding debt under the revolving line of credit. Draws on the line of credit are made based on theborrowing capacity one week in arrears. As of December 31, 2013, the Company had a borrowing capacity of $3.0 million based on the Company’scollateralized assets. As such, the Company had ability to borrow $3.0 million under the revolving line of credit at December 31, 2013. The maturity date ofthe revolving line of credit is March 31, 2014.These credit facilities are secured by substantially all of our assets. The credit agreements include customary affirmative, negative and financialcovenants. For example, we are restricted from incurring additional debt, disposing of or pledging our assets, entering into merger or acquisition agreements,making certain investments, allowing fundamental changes to our business, ownership, management or business locations, and from making certainpayments in respect of stock or other ownership interests, such as dividends and stock repurchases. Under our loan arrangements, as in effect atDecember 31, 2013 and as modified in August 2013, we are required to meet EBITDA and liquidity covenants as defined in the loan agreement. We are alsorequired under the credit agreements to maintain our primary operating account and the majority of our cash and investment balances in accounts with ourprimary lending bank. As of the amendment date and as of December 31, 2013, we were in compliance with all covenants of this agreement.We expect to have negative cash flow from operations into 2014. Throughout 2014, we expect to continue the development and commercialization of ourexisting products, our research and development programs and the advancement of new products into clinical development. During 2014, we expect operatingexpenses to be generally consistent with 2013 with additional investment in certain targeted areas.We may be required to raise capital or pursue other financing strategies to continue our operations. Until we can generate significant cash flow from ouroperations, we expect to continue to fund our operations with cash resources primarily generated from the proceeds of our past and future public offerings,private sales of our equity securities and working capital and equipment financing loans. In the future, we may finance cash needs through the sale of otherequity securities or non-core assets, strategic collaboration agreements, debt financings or through distribution rights. We cannot accurately predict the timingand amount of our utilization of capital, which will depend on a number of factors outside of our control. Our existing cash, cash equivalents and borrowingfacilities may not be sufficient to fund our operating expenses and capital equipment requirements through the next 12 months, which would require us toobtain additional equity or other financing before that time. We cannot assure that such additional financing will be available on a timely basis on termsacceptable to us or at all, or that such financing will not be dilutive to our stockholders. If adequate funds are not available to us, we could be required to delaydevelopment or commercialization of new products, to license to third parties the rights to commercialize products or technologies that we would otherwise seekto commercialize ourselves or to reduce the sales, marketing, customer support or other resources devoted to our products, any of which could 55have a material adverse effect on our business, financial condition and results of operations. In addition, we could be required to cease operations.Off-Balance Sheet ArrangementsWe do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities often referredto as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or othercontractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As a result, we are notmaterially exposed to any financing, liquidity, market or credit risk that could have arisen if we had engaged in these relationships.Contractual ObligationsThe following table summarizes all significant contractual payment obligations by payment due date: Payments by Period (In thousands) Under1 Year 1–3Years 3–5Years Over5 Years Total Long-term debt $50 $99 $18,382 $— $18,531 Operating leases $1,594 $3,493 $3,990 $— $9,077 Total $1,644 $3,592 $22,372 $— $27,608 Commercial CommitmentsIn 2012, we entered into a letter of credit to support a commitment in the amount of approximately $0.1 million. This letter of credit is valid through2015. ITEM 7A.Quantitative and Qualitative Disclosures About Market RiskForeign Exchange RiskWe operate mainly in the U.S., Europe and Asia and we expect to continue to sell our products both within and outside of the U.S. Although the majorityof our revenue and expenses are transacted in U.S. dollars, a portion of our operations are conducted in Euros and to a lesser extent, in other currencies. Assuch, we have foreign exchange exposure with respect to non-U.S. dollar revenues and expenses as well as cash balances, accounts receivable, accountspayable and other asset and liability balances denominated in non-US dollar currencies. Our international operations are subject to risks typical ofinternational operations, including, but not limited to, differing economic conditions, changes in political climate, differing tax structures, other regulationsand restrictions, and foreign exchange rate volatility. Future fluctuations in the value of these currencies may affect the price competitiveness of our products.In addition, because we have a relatively long installation cycle for our systems, we will be subject to risk of currency fluctuations between the time we executea purchase order and the time we deliver the system and collect payments under the order, which could adversely affect our operating margins. As ofDecember 31, 2013 we have not hedged exposures in foreign currencies or entered into any other derivative instruments.For the year ended December 31, 2013, sales denominated in foreign currencies were approximately 15.3% of total revenue. For the year endedDecember 31, 2013, our revenue would have decreased by approximately $0.6 million if the U.S. dollar exchange rate used would have strengthened by 10%.For the year ended December 31, 2013, expenses denominated in foreign currencies were approximately 13.5% of our total expenses. For the year endedDecember 31, 2013, our operating expenses would have decreased by approximately $0.5 million if the U.S. dollar exchange rate used would havestrengthened by 10%. In addition, 56we have assets and liabilities denominated in foreign currencies. A 10% strengthening of the U.S. dollar exchange rate against all currencies with which wehave exposure at December 31, 2013 would have resulted in a $0.1 million decrease in the carrying amounts of those net assets.Interest Rate RiskWe have exposure to interest rate risk related to our investment portfolio. The primary objective of our investment activities is to preserve principal whileat the same time maximizing the income we receive from our invested cash without significantly increasing the risk of loss. Our interest income is sensitive tochanges in the general level of U.S. interest rates, particularly since the majority of our investments are in short-term debt instruments. We invest our excesscash primarily in U.S. government securities and marketable debt securities of financial institutions and corporations with strong credit ratings. Theseinstruments generally have maturities of two years or less when acquired. We do not utilize derivative financial instruments, derivative commodityinstruments or other market risk sensitive instruments, positions or transactions. Accordingly, we believe that while the instruments we hold are subject tochanges in the financial standing of the issuer of such securities, we are not subject to any material risks arising from changes in interest rates, foreigncurrency exchange rates, commodity prices, equity prices or other market changes that affect market risk sensitive instruments.We have exposure to market risk related to any investments we might hold. Market liquidity issues might make it impossible for the Company toliquidate its holdings or require that the Company sell the securities at a substantial loss. As of December 31, 2013, the Company did not hold anyinvestments other than those held in money market funds.We have exposure to interest rate risk related to our borrowings as the interest rates for certain of our outstanding loans are subject to increase should theinterest rate increase above a defined percentage. Because certain issuances of our outstanding debt are subject to minimum interest rates ranging from 5.75%to 7.0%, a hypothetical increase in interest rates of 100 basis points would have no impact on interest expense due to interest rate floors on our floating ratedebt.Inflation RiskWe do not believe that inflation has had a material adverse impact on our business or operating results during the periods covered by this report. 57ITEM 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATAFinancial StatementsIndex To Financial Statements PAGE Report of Ernst & Young LLP, Independent Registered Public Accounting Firm 59 Balance Sheets at December 31, 2013 and 2012 60 Statements of Operations for the years ended December 31, 2013, 2012, and 2011 61 Statements of Stockholders’ Equity for the years ended December 31, 2013, 2012, and 2011 62 Statements of Cash Flows for the years ended December 31, 2013, 2012, and 2011 63 Notes to the Financial Statements 64 Schedule II—Valuation and Qualifying Accounts 92 All other schedules have been omitted because they are not applicable or the required information is shown in the Financial Statements or the Notesthereto. 58Report of Independent Registered Public Accounting FirmThe Board of Directors and StockholdersStereotaxis, Inc.We have audited the accompanying balance sheets of Stereotaxis, Inc. (the Company) as of December 31, 2013 and 2012, and the related statements ofoperations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2013. Our audits also included the financialstatement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Ourresponsibility is to express an opinion on these financial statements and schedule based on our audits.We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standardsrequire that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were notengaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financialreporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on theeffectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a testbasis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates madeby management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Stereotaxis, Inc. at December 31,2013 and 2012, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S.generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financialstatements taken as a whole, presents fairly in all material respects the information set forth herein.The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described inNote 1, the Company has incurred recurring operating losses and has a net capital deficiency. These conditions raise substantial doubt about the Company’sability to continue as a going concern. Management’s plans in regard to these matters also are described in Note 1. The financial statements do not include anyadjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may resultfrom the outcome of this uncertainty regarding the Company’s ability to continue as a going concern./s/ Ernst & Young LLPSt. Louis, MissouriMarch 27, 2014 59STEREOTAXIS, INC.BALANCE SHEETS

“Registrant,” “we,” “us,” and “our” refer to Stereotaxis, Inc. and its wholly-ownedsubsidiaries. Niobe, Epoch™, Odyssey, Odyssey Cinema™, Vdrive™, Vdrive Duo™, V-Loop™, and V-Sono™ are trademarks of Stereotaxis, Inc.1. Description of BusinessStereotaxis designs, manufactures and markets the Epoch Solution, which is an advanced remote robotic navigation system for use in a hospital’sinterventional surgical suite, or “interventional lab”, that we believe revolutionizes the treatment of arrhythmias and coronary artery disease by enablingenhanced safety, efficiency and efficacy for catheter-based, or interventional, procedures. The Epoch Solution is comprised of the Niobe ES Robotic MagneticNavigation System (“Niobe ES system”), Odyssey Information Management Solution (“Odyssey Solution”), and the Vdrive Robotic Navigation System (“Vdrive system”).The Niobe system is designed to enable physicians to complete more complex interventional procedures by providing image guided delivery of cathetersand guidewires through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern themotion of the working tip of the catheter or guidewire, resulting in improved navigation, efficient procedures and reduced x-ray exposure.In addition to the Niobe system and its components, Stereotaxis also has developed the Odyssey Solution, which consolidates all lab informationenabling doctors to focus on the patient for optimal procedure efficiency. The system also features a remote viewing and recording capability called OdysseyCinema, which is an innovative solution delivering synchronized content for optimized workflow, advanced care and improved productivity. This toolincludes an archiving capability that allows clinicians to store and replay entire procedures or segments of procedures. This information can be accessed fromlocations throughout the hospital local area network and over the global Odyssey Network providing physicians with a tool for clinical collaboration, remoteconsultation and training.Our Vdrive system provides navigation and stability for diagnostic and therapeutic devices designed to improve interventional procedures. The Vdrivesystem complements the Niobe ES system control of therapeutic catheters for fully remote procedures and enables single-operator workflow and is sold as twooptions, the Vdrive system and the Vdrive Duo system. In addition to the Vdrive system and the Vdrive Duo system, we also manufacture and marketvarious disposable components which can be manipulated by these systems.We promote the full Epoch Solution in a typical hospital implementation, subject to regulatory approvals or clearances. The full Epoch Solutionimplementation requires a hospital to agree to an upfront capital payment and recurring payments. The upfront capital payment typically includes equipmentand installation charges. The recurring payments typically include disposable costs for each procedure, equipment service costs beyond warranty period, andsoftware licenses. In hospitals where the full Epoch Solution has not been implemented, equipment upgrade or expansion can be implemented upon purchasingof the necessary upgrade or expansion.The core components of Stereotaxis systems have received regulatory clearance in the U.S., Europe, Canada and elsewhere; V-Sono ICE CatheterManipulator has received U.S. regulatory clearance and the V-Loop Circular Catheter Manipulator is expected to be submitted for review by the U.S. Food andDrug Administration in early 2014.Since our inception, we have generated significant losses. As of December 31 2013, we had incurred cumulative net losses of approximately $453.4million. In May 2011, the Company introduced the Niobe ES system and as of December 31, 2013, the Company had an installed base of 100 Niobe ESsystems and has 64®®received positive feedback from the physicians at these sites. Between 2011 and 2013, the Company implemented a wide ranging plan to rebalance and reduceoperating expenses by 15% to 20% on an annual run rate basis. We expect to incur additional losses into 2014 as we continue the development andcommercialization of our products, conduct our research and development activities and advance new products into clinical development from our existingresearch programs and fund additional sales and marketing initiatives. During 2014, we expect operating expenses to be generally consistent with 2013 withadditional investment in certain targeted areas.We may be required to raise capital or pursue other financing strategies to continue our operations. Until we can generate significant cash flow from ouroperations, we expect to continue to fund our operations with cash resources primarily generated from the proceeds of our past and future public offerings,private sales of our equity securities and working capital and equipment financing loans. In the future, we may finance cash needs through the sale of otherequity securities or non-core assets, strategic collaboration agreements, debt financings or through distribution rights. We cannot accurately predict the timingand amount of our utilization of capital, which will depend on a number of factors outside of our control.Our existing cash, cash equivalents and borrowing facilities may not be sufficient to fund our operating expenses and capital equipment requirementsthrough the next 12 months, which would require us to obtain additional financing before that time. Further, our revolving line of credit with Silicon ValleyBank matures on March 31, 2014. We cannot assure that additional financing will be available on a timely basis on terms acceptable to us or at all, or thatsuch financing will not be dilutive to our stockholders. If adequate funds are not available to us, we could be required to delay development orcommercialization of new products, to license to third parties the rights to commercialize products or technologies that we would otherwise seek tocommercialize ourselves or to reduce the sales, marketing, customer support or other resources devoted to our products, any of which could have a materialadverse effect on our business, financial condition and results of operations. In addition, we could be required to cease operations.2. Summary of Significant Accounting PoliciesCash and Cash EquivalentsThe Company considers all short-term investments purchased with original maturities of three months or less to be cash equivalents. The Companyplaces its cash with high-credit-quality financial institutions and invests primarily in money market accounts. In 2012, we entered into a letter of credit tosupport a commitment in the amount of approximately $0.1 million. This letter of credit is valid through 2015. No cash was restricted at December 31, 2013or 2012.Accounts Receivable and Allowance for Uncollectible AccountsAccounts receivable primarily include amounts due from hospitals and distributors for acquisition of magnetic systems, associated disposable devicesales and service contracts. Credit is granted on a limited basis, with balances due generally within 30 days of billing. The provision for bad debts is basedupon management’s assessment of historical and expected net collections considering business and economic conditions and other collection indicators.Financial InstrumentsFinancial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, accounts payable and debt. The carryingvalue of such amounts reported at the applicable balance sheet dates approximates fair value. See Note 9 for disclosure of the fair value of debt.The Company measures certain financial assets and liabilities at fair value on a recurring basis, including warrants. General accounting principles forfair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives thehighest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs(“Level 3”). See Note 12 for disclosure of fair value measurements. 65InventoryThe Company values its inventory at the lower of cost, as determined using the first-in, first-out (FIFO) method, or market. The Company periodicallyreviews its physical inventory for obsolete items and provides a reserve upon identification of potential obsolete items.Property and EquipmentProperty and equipment consist primarily of computer, office, and research and demonstration equipment held for lease and leasehold improvementsand are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives or life of the base lease term, ranging from three toten years.Long-Lived AssetsIf facts and circumstances suggest that a long-lived asset may be impaired, the carrying value is reviewed. If this review indicates that the carrying valueof the asset will not be recovered, as determined based on projected undiscounted cash flows related to the asset over its remaining life, the carrying value of theasset is reduced to its estimated fair value.Intangible AssetsIntangible assets consist of purchased technology and intellectual property rights valued at cost on the acquisition date and amortized over their estimateduseful lives of 10-15 years. If facts and circumstances suggest that an intangible asset may be impaired, the carrying value is reviewed. If this review indicatesthat the carrying value of the asset will not be recovered, as determined based on projected undiscounted cash flows related to the asset over its remaining life,the carrying value of the asset is reduced to its estimated fair value.Use of EstimatesThe preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates andassumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statementsand the reported amounts of income and loss during the reporting period. Actual results could differ from those estimates.Revenue and Costs of RevenueThe Company adopted Accounting Standards Update 2009-13, Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”) in the fourth quarterof 2009, effective as of January 1, 2009.ASU 2009-13 permits management to estimate the selling price of undelivered components of a bundled sale for which it is unable to establish vendor-specific objective evidence (“VSOE”) or third-party evidence (“TPE”). This requires management to record revenue for certain elements of a transaction eventhough it might not have delivered other elements of the transaction, for which it was unable to meet the requirements for establishing VSOE or TPE. TheCompany believes that the guidance significantly improves the reporting of these types of transactions to more closely reflect the underlying economiccircumstances. This guidance also prohibits the use of the residual method for allocating revenue to the various elements of a transaction and requires that therevenue be allocated proportionally based on the relative estimated selling prices.Under our revenue recognition policy, a portion of revenue for Niobe systems, Vdrive systems and certain Odyssey systems is recognized upondelivery, provided that title has passed, there are no uncertainties regarding acceptance, persuasive evidence of an arrangement exists, the sales price is fixedand determinable, and collection of the related receivable is reasonably assured. Revenue is recognized for other types of Odyssey systems upon completion ofinstallation, since there are no qualified third party installers. When installation is the responsibility of the customer, revenue from system sales is recognizedupon shipment since these arrangements do not include an installation element or right of return privileges. The Company does not 66recognize revenue in situations in which inventory remains at a Stereotaxis warehouse or in situations in which title and risk of loss have not transferred to thecustomer. Amounts collected prior to satisfying the above revenue recognition criteria are reflected as deferred revenue. Revenue from services and license fees,whether sold individually or as a separate unit of accounting in a multiple-deliverable arrangement, is deferred and amortized over the service or license feeperiod, which is typically one year. Revenue from services is derived primarily from the sale of annual product maintenance plans. We recognize revenue fromdisposable device sales or accessories upon shipment and establish an appropriate reserve for returns. The return reserve, which is applicable only todisposable devices, is estimated based on historical experience which is periodically reviewed and updated as necessary. In the past, changes in estimate havehad only a de minimus effect on revenue recognized in the period. We believe that the estimate is not likely to change significantly in the future.Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and productmaintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and arerecorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred.Research and Development CostsInternal research and development costs are expensed in the period incurred. Amounts receivable from strategic alliances under research reimbursementagreements are recorded as a contra-research and development expense in the period reimbursable costs are incurred. There were no material receivables atDecember 31, 2013 or 2012 under these types of agreements. Advance receipts or other unearned reimbursements are included in accrued liabilities on theaccompanying balance sheet until earned.Share-Based CompensationStock options or stock appreciation rights issued to certain non-employees are recorded at their fair value as determined in accordance with generalaccounting principles for share-based payments and accounting for equity instruments that are issued to other than employees for acquiring, or in conjunctionwith selling, goods or services, and recognized over the service period. Deferred compensation for options granted to non-employees is remeasured on aquarterly basis through the vesting or forfeiture date.The Company utilized the Black-Scholes valuation model to determine the fair value of share-based payments at the date of previously issued grantusing risk-free interest rate based on the Treasury yield on the date of the grant and expected volatility based on the Company’s historical volatility over theexpected term of the option. The resulting compensation expense is recognized over the requisite service period, generally one to four years. Compensationexpense is recognized only for those awards expected to vest, with forfeitures estimated based on the Company’s historical experience and future expectations.Restricted shares granted to employees are valued at the fair market value at the date of grant. The Company amortizes the amount to expense over theservice period on a straight-line basis for those shares with graded vesting. If the shares are subject to performance objectives, the resulting compensationexpense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.Shares purchased by employees under the 2004 Employee Stock Purchase Plan were considered to be compensatory and were accounted for inaccordance with general accounting principles for share-based payments.Net Loss per Common ShareBasic loss per common share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding duringthe period. Diluted loss per share is computed by dividing the loss for the period by the weighted average number of common and common equivalent sharesoutstanding during the 67period. In addition, the application of the two-class method of computing earnings per share under general accounting principles for participating securities isnot applicable because the Company’s unearned restricted shares do not contractually participate in its losses.The Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights or warrants in the calculation ofdiluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the two-class method of computingearnings per share under general accounting principles for participating securities is not applicable during these periods because those securities do notcontractually participate in its losses.On July 10, 2012, the Company effected a one-for-ten reverse stock split of the Company’s common stock. The net loss per common share, sharesoutstanding, and weighted average shares outstanding reported in the financial statements and notes to the financial statements for the periods endingDecember 31, 2013, 2012, and 2011 are presented on a post-split basis. See Note 11 for additional discussion of the reverse stock split.As of December 31, 2013, the Company had 188,947 shares of common stock issuable upon the exercise of outstanding options and stock appreciationrights at a weighted average exercise price of $48.38 per share and 3,021,302 shares of common stock issuable upon the exercise of outstanding warrants at aweighted average exercise price of $14.21 per share. The Company had a weighted average of 33,058 unearned restricted shares outstanding for the periodended December 31, 2013.Income TaxesIn accordance with general accounting principles for income taxes, a deferred income tax asset or liability is determined based on the difference betweenthe financial statement and tax basis of assets and liabilities as measured by the enacted tax rates that will be in effect when these differences reverse. TheCompany provides a valuation allowance against net deferred income tax assets unless, based upon available evidence, it is more likely than not the deferredincome tax assets will be realized.Product Warranty ProvisionsThe Company’s standard policy is to warrant all systems against defects in material or workmanship for one year following installation. TheCompany’s estimate of costs to service the warranty obligations is based on historical experience and current product performance trends. A regular review ofwarranty obligations is performed to determine the adequacy of the reserve and adjustments are made to the estimated warranty liability (included in otheraccrued liabilities) as appropriate.Patent CostsCosts related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain.Concentrations of RiskThe majority of the Company’s cash, cash equivalents and investments are deposited with one major financial institution in the U.S. Deposits in thisinstitution exceed the amount of insurance provided on such deposits.One customer, Biosense Webster Inc., as our distributor, accounted for $3,902,178, $3,447,386, and $3,663,687, or 10%, 7% and 9%, of total netrevenue for the years ended December 31, 2013, 2012, and 2011, respectively. No other single customer accounted for more than 10% of total revenue for theyear ended December 31, 2013. 68ReclassificationsCommon stock and additional paid-in capital in the prior year’s financial statements have been reclassified to reflect the one-for-ten reverse stock spliteffected on July 10, 2012. Refer to Note 11 for additional discussion of the reverse stock split.Recently Issued Accounting PronouncementsIn February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2013-02,“Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” which adds new disclosure requirements foritems reclassified out of accumulated other comprehensive income (“AOCI”). The update requires that the Company present either in a single note orparenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of AOCI based on its source and theincome statement line items affected by the reclassification. The guidance is effective for interim and annual reporting periods beginning on or afterDecember 15, 2012. As the Company has no items of other comprehensive income, the Company is not required to report accumulated other comprehensiveincome.In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-11, “Disclosures aboutOffsetting Assets and Liabilities.” The Update enhances the disclosure of offsetting assets and liabilities by requiring companies to disclose both the gross andnet information about instruments and transactions eligible for offset as well as those subject to an agreement similar to master netting arrangements. Thisguidance is effective for the Company’s interim and annual periods beginning January 1, 2013. The adoption of this pronouncement did not have an impacton the financial statements.In June 2011, the FASB issued new accounting guidance related to the presentation of comprehensive income that increases comparability between U.S.GAAP and International Financial Reporting Standards (“IFRS”). This guidance eliminates the current option to report other comprehensive income (OCI) andits components in the statement of changes in stockholders’ equity. This guidance was effective for the Company’s interim and annual periods beginningJanuary 1, 2012. As the Company has no items of other comprehensive income, the Company is not required to report comprehensive income or othercomprehensive income.In May 2011, the FASB issued Accounting Standards Update No. 2011-04, “Fair Value Measurement: Amendments to Achieve Common Fair ValueMeasurement and Disclosure Requirements in U.S. GAAP and IFRS.” The Update amends the guidance on fair value measurements to develop commonrequirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. GAAP and IFRS. The Updatedoes not require additional fair value measurements and is not intended to establish valuation standards or affect valuation practices outside of financialreporting. This guidance was effective during interim and annual periods beginning after December 15, 2011. The adoption of this ASU did not have amaterial effect on our financial position or results of operations.3.

Thewarrants are exercisable at $40.15 per share, beginning on March 1, 2011 and expiring on February 28, 2016. The fair value of these warrants of$1,747,392, calculated using the Black-Scholes method, was deferred and amortized to interest expense ratably. As the previous guarantee was no longer ineffect, the Company expensed in 2010 the entire balance on the warrants issued to the Lenders in October 2009.In December 2010, the Company further amended its agreement with its primary lender to extend the maturity of the current working capital line ofcredit from March 31, 2011 to March 31, 2012, retaining the $30 million total availability under the line per the 2009 amendment.

The Reverse Stock Split was effective as of July 10, 2012, and the Company’s common stock began trading on the NASDAQ Global Marketon a post-split basis on July 11, 2012.As a result of the Reverse Stock Split, each ten shares of the Company’s issued and outstanding common stock were automatically combined andconverted into one issued and outstanding share of common stock. The Reverse Stock Split affected all issued and outstanding shares of the Company’scommon stock, as well as common stock underlying stock options, stock appreciation rights, restricted stock, restricted stock units, warrants andconvertible debentures outstanding immediately prior to the effectiveness of the Reverse Stock Split. The Reverse Stock Split reduced the number of shares ofthe Company’s common stock outstanding from approximately 78 million to 7.8 million at the time of the Reverse Stock Split. In addition, the Amendmentincreased the number of authorized shares of the Company’s common stock from 100 million to 300 million. The Reverse Stock Split did not alter the parvalue of common stock, which remained $0.001 per share, or modify any voting rights or other terms of the Company’s common stock. Unless otherwiseindicated, all information set forth herein gives effect to such Reverse Stock Split.Public Offerings of Common StockIn May 2012, the Company entered into a Stock and Warrant Purchase Agreement with certain institutional investors whereby it agreed to sell anaggregate of approximately 2.17 million shares of the Company’s common stock (the “PIPE Common Stock”) at a price of $3.361 per share, together with six-year warrants at a price of $1.25 per share to purchase an aggregate of approximately 2.17 million shares of common stock having an exercise price of $3.361per share (the “PIPE Warrants”). Each purchaser received a PIPE Warrant to purchase one share of common stock for every share of PIPE Common Stockpurchased. Net proceeds from the sale of the securities were approximately $9.1 million, after placement agent fees and other offering expenses. The Companyused the funds to repay $7 million of the revolving credit facility guaranteed by the Lenders and plans to use the balance for working capital and generalcorporate purposes.On August 7, 2013, venture funds affiliated with Sanderling Ventures received an aggregate of 183,478 shares of common stock based upon thecashless exercise of warrants to purchase an aggregate of 262,450 shares of common stock. These warrants were comprised of 75,758 warrants with anexercise price of $1.98 per share, 156,204 warrants with an exercise price of $3.361 per share and 30,488 warrants with an exercise price of $4.10 per share.The warrants were issued by the Company in private placements in 2012 and 2013 in connection with the extension of previously disclosed guarantees.On August 13, 2013, venture funds affiliated with Sanderling Ventures exercised PIPE Warrants to purchase an aggregate of 650,619 shares ofcommon stock in a cashless net exercise as provided for in the PIPE Warrants, which resulted in the issuance to such funds of an aggregate of 308,194 sharesof common stock. As a result, there were no net proceeds to the Company.On August 16, 2013, certain affiliates of Franklin Templeton exercised PIPE Warrants to purchase an aggregate of 650,618 shares of common stockfor cash. The Company received an aggregate of $2,186,727 gross proceeds from the sale.On August 16, 2013, Alafi Capital Company exercised PIPE Warrants to purchase an aggregate of 261,241 shares of common stock for cash.

Refer to Note 9 for the discussion of warrants issued in conjunction with debtofferings.On November 27, 2013, the Company announced the results of its previously announced offering of subscription rights to purchase shares of itscommon stock, par value $0.001 per share. Pursuant to the rights 76offering, subscription rights to purchase approximately 3.4 million shares of common stock were exercised, resulting in gross proceeds to Stereotaxis ofapproximately $10.2 million.The holders of common stock are entitled one vote for each share held and to receive dividends whenever funds are legally available and when declaredby the Board of Directors subject to the prior rights of holders of all classes of stock having priority rights as dividends and the conditions of the ourRevolving Credit Agreement. No dividends have been declared or paid as of December 31, 2013.The Company has reserved shares of common stock for the exercise of warrants, the issuance of options granted under the Company’s stock optionplan and its stock purchase plan as follows: December 31,2013 December 31,2012 Warrants 3,021,302 6,099,476 Stock award plans 1,032,462 131,464 4,053,764 6,230,940 Stock Award PlansThe Company has various stock plans that permit the Company to provide incentives to employees and directors of the Company in the form of equitycompensation. In August 2012, the Board of Directors adopted a stock incentive plan (the 2012 Stock Incentive Plan) which was subsequently approved bythe Company’s stockholders. This plan replaces the 2002 Stock Incentive Plan which expired on March 25, 2012.The 2012 Stock Incentive Plan allows for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted sharesand restricted share units to employees, directors, and consultants. Options granted under the 2012 Stock Incentive Plan expire no later than ten years from thedate of grant. The exercise price of each incentive stock option shall not be less than 100% of the fair value of the stock subject to the option on the date theoption is granted. The vesting provisions of individual options may vary, but incentive stock options generally vest 25% on the first anniversary of each grantand 1/48 per month over the next three years. Stock appreciation rights are rights to acquire a calculated number of shares of the Company’s common stockupon exercise of the rights. The number of shares to be issued is calculated as the difference between the exercise price of the right and the aggregate marketvalue of the underlying shares on the exercise date divided by the market value as of the exercise date. Stock appreciation rights granted under the 2012 StockIncentive Plan generally vest 25% on the first anniversary of such grant and 1/48 per month over the next three years and expire no later than ten years fromthe date of grant. The Company generally issues new shares upon the exercise of stock options and stock appreciation rights.Restricted share grants are either time-based or performance-based. Time-based restricted shares generally cliff vest three years after grant. Performance-based restricted shares vest upon the achievement of performance objectives which are determined by the Company’s Board of Directors.Restricted stock unit grants are time-based and generally vest over a period of four years. Options granted to non-employee directors expire no later thanten years from the date of grant. The exercise price of options to non-employee directors shall not be less than 100% of the fair value of the stock subject to theoption on the date the option is granted. Initial grants of options to new directors generally vest over a two year period. Annual grants to directors generally vestupon the earlier of one year or the next stockholder meeting. 77A summary of the option and stock appreciation rights activity for the year ended December 31, 2013 is as follows: Number ofOptions/SARs Range ofExercise Price WeightedAverage ExercisePrice per Share Outstanding, December 31, 2012 373,899 $1.63 - $116.40 $43.90 Granted — $0.00 - $0.00 — Exercised (145) $6.80 - $6.80 $6.80 Forfeited (184,807) $1.69 - $68.60 $39.34 Outstanding, December 31, 2013 188,947 $1.63 - $116.40 $48.38 As of December 31, 2013, the weighted average remaining contractual life of the options and stock appreciation rights outstanding was 3.88 years.

The intrinsicvalue of the options and stock appreciation rights outstanding at December 31, 2013 and the intrinsic value of fully vested options and stock appreciationrights outstanding at December 31, 2013 were less than $0.1 million based on a closing share price of $3.62 on December 31, 2013. During the year endedDecember 31, 2013, the aggregate intrinsic value of options and stock appreciation rights exercised under the Company’s stock option plans was less than$0.1 million. No options or SARS were granted during the year ended December 31, 2013.During the year ended December 31, 2013 the Company realized less than $0.1 million from the exercise of stock options and stock appreciation rights.The Company realized $0 and less than $0.1 million from the exercise of stock options and stock appreciation rights during 2012 and 2011, respectively.A summary of the restricted share grant activity for the year ended December 31, 2013 is as follows: Number ofShares Weighted AverageGrant Date FairValue per Share Outstanding, December 31, 2012 68,543 $20.62 Granted — — Vested (33) $33.80 Forfeited (61,910) $19.06 Outstanding, December 31, 2013 6,600 $35.20 78A summary of the restricted stock unit activity for the year ended December 31, 2013 is as follows: Number ofRestricted StockUnits Weighted AverageGrant Date FairValue per Unit Outstanding, December 31, 2012 529,312 $2.64 Granted 449,000 $2.20 Vested (211,615) $3.82 Forfeited (177,938) $2.09 Outstanding, December 31, 2013 588,759 $2.05 A summary of the restricted shares outstanding as of December 31, 2013 is as follows: Number ofShares Time based restricted shares 6,600 Performance based restricted shares — Outstanding, December 31, 2013 6,600 The intrinsic value of restricted shares and restricted stock units outstanding at December 31, 2013 was less than $0.1 million and $2.1 million,respectively, based on a closing share price of $3.62 as of December 31, 2013. During the year ended December 31, 2013, the aggregate intrinsic value ofrestricted shares and restricted stock units vested was approximately $0 and $0.3 million, respectively, determined at the date of vesting.During the year ended December 31, 2013, the Company determined that it was not probable that the performance conditions related to certain of itsoutstanding restricted share awards would be achieved and accordingly, recorded approximately $(0.2) million as a cumulative catch-up adjustment resultingin a reduction of share based compensation. During the second quarter of 2013, the Company made an adjustment to its forfeiture rate based on historicalinformation, which resulted in a reduction of share-based compensation of $(0.5) million for the year ended December 31, 2013.As of December 31, 2013, the total compensation cost related to options, stock appreciation rights and non-vested stock granted to employees under theCompany’s stock award plans but not yet recognized was approximately $1.3 million, net of estimated forfeitures of approximately $1.2 million. This costwill be amortized over a period of up to four years on a straight-line basis over the underlying estimated service periods and will be adjusted for subsequentchanges in estimated forfeitures.2009 Employee Stock Purchase PlanIn 2009, the Company adopted its 2009 Employee Stock Purchase Plan and reserved 25,000 shares of common stock for issuance pursuant to the plan.The Company offered employees the opportunity to participate in the plan beginning July 1, 2009 with an initial purchase date of September 30, 2009. Eligibleemployees had the opportunity to participate in a new purchase period every 3 months. Under the terms of the plan, employees could purchase up to 15% oftheir compensation of the Company’s common stock, subject to an annual maximum of $25,000, at 95% of the fair market value of the stock at the end ofthe purchase period, subject to certain plan limitations. The plan was suspended in 2012 and no shares were available for issuance as of December 31, 2013.12. Fair Value MeasurementsThe Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents and warrants. Generalaccounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fairvalue. The hierarchy gives the 79highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs(“Level 3”). The three levels of the fair value hierarchy are described below: Level 1: Values are based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets orliabilities.Level 2: Values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets thatare not active, or other model-based valuation techniques for which all significant assumptions are observable in the market.Level 3: Values are generated from model-based techniques that use significant assumptions not observable in the market.The following table sets forth the Company’s assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy. Asrequired by the Fair Value Measurements and Disclosures topic of the Accounting Standards Codification, assets and liabilities are classified in their entiretybased on the lowest level of input that is significant to the fair value measurement. Fair Value Measurement Using Total Quoted Prices inActive Marketsfor IdenticalInstruments SignificantOtherObservableInputs (Level 2) SignificantUnobservableInputs(Level 3) Assets at December 31, 2013: Cash equivalents $11,995,481 11,995,481 — — Total assets at fair value $11,995,481 11,995,481 — — Liabilities at December 31, 2013: Warrants issued December 29, 2008 $16,863 — — 16,863 Warrants issued May 10, 2012 1,915,753 — — 1,915,753 Warrants issued August 2013 3,712,010 3,712,010 Total liabilities at fair value: $5,644,626 — — 5,644,626 Assets at December 31, 2012: Cash equivalents $256,702 256,702 — — Derivative asset 1,736 — — 1,736 Total assets at fair value $258,438 256,702 — 1,736 Liabilities at December 31, 2012: Warrants issued December 29, 2008 $71,581 — — 71,581 Warrants issued May 10, 2012 2,347,902 — — 2,347,902 Derivative liability 548,865 — — 548,865 Total liabilities at fair value: $2,968,348 — — 2,968,348 Level 1The Company’s financial assets consist of cash equivalents invested in money market funds in the amount of $11,995,481 and $256,702 atDecember 31, 2013 and December 31, 2012, respectively. These assets are classified as Level 1 as described above and total interest income recorded for theseinvestments was insignificant during both the years ended December 31, 2013 and December 31, 2012. There were no transfers in or out of Level 1 during theyear ended December 31, 2013. 80Level 2The Company does not have any financial assets or liabilities classified as Level 2.Level 3In conjunction with its December 29, 2008 registered direct offering, the Company issued warrants to purchase 179,241 shares of the Company’scommon stock that contained a provision that required a reduction of the exercise price if certain equity events occurred. Under the provisions of generalaccounting principles for derivatives and hedging activities and determining whether an instrument (or embedded feature) is indexed to an entity’s own stock,such a reset provision does not meet the exemptions for equity classification and as such, the Company accounts for these warrants as derivative instruments.The calculated fair value of the warrants is classified as a liability and is periodically remeasured with any changes in value recognized in “Other income(expense)” in the Statement of Operations. General accounting principles for determining whether an instrument (or embedded feature) is indexed to an entity’sown stock became effective for the Company as of January 1, 2009. Accordingly, the fair value of the warrants as of that date was reclassified fromstockholders’ equity into current liabilities.In accordance with general accounting principles for fair value measurement, the Company’s warrants in the amount of $16,863 were measured at fairvalue on a recurring basis as of December 31, 2013 and were valued using Level 3 valuation inputs. A Black-Scholes model was used to value the Company’swarrants at December 31, 2013 using the following assumptions: 1) dividend yield of 0%; 2) volatility of 112.66%; 3) risk-free interest rate of 0.78%; and 4)expected life of 0.5 years.In the Company’s May 2012 financing transaction, the Company issued subordinated convertible debentures and warrants. The optional conversionfeature of the subordinated convertible debentures is classified as a derivative liability within “Warrants and derivative liabilities” on the Company’s balancesheet. The warrants issued in conjunction with the Debentures and PIPE are also considered a liability. Due to the provisions included in the warrantagreements, the warrants do not meet the exemptions for equity classification and as such, the Company accounts for these warrants as derivativeinstruments. The warrants and derivative liability were periodically remeasured with any changes in value recognized in “Other income (expense)” in theStatement of Operations.Per the terms of the Debentures agreement, the Company had the ability to require each holder to convert up to 50% of the Debentures if the commonstock closed above $15.00, or 100% of the Debentures if the common stock closed above $20.00 (in each case, as adjusted for stock splits, recapitalizationsand similar events) during a 20 consecutive trading day period and the resale registration statement had been declared effective by the SEC and was availablefor the issuance of the common stock upon conversion of the Debentures. In the event of any forced conversion by the Company, the minimum amount thatthe Company could force the holders to convert was $2.5 million of Debentures in the aggregate. This mandatory redemption clause was classified as aderivative asset within “Prepaid and other current assets” on the Company’s balance sheet. The derivative asset was periodically remeasured with any changesin value recognized in “Other income (expense)” in the Statement of Operations.A Monte-Carlo simulation was used to value the derivative asset, liabilities and warrants upon issuance on May 10, 2012 using the followingassumptions: 1) volatility of 80%; 2) risk-free interest rate of 1.035%; and 3) a closing stock price of $3.413. Based on the discussion of the Debentures inNote 11, the Debentures along with their derivative liability and asset, and related warrants were extinguished in the third quarter of 2013.The initial valuation of Exchange warrants were valued as of August 7, 2013 using the following assumptions: 1) volatility of 111%; 2) risk-freeinterest rate of 1.46%; and 3) a closing stock price of $8.69.In accordance with general accounting principles for fair value measurement, the remaining PIPE and Exchange warrants were revalued as ofDecember 31, 2013 using the following assumptions: 1) volatility of 142.28%; 2) risk-free interest rate of 1.75%; and 3) a closing stock price of $3.62. 81The significant unobservable input used in the fair value measurement of the Company’s warrants is volatility. Significant increases (decreases) in thevolatility in isolation would result in a significantly higher (lower) asset and liability fair value measurements.The following table sets forth a summary of changes in the fair value of the Company’s Level 3 financial asset and liabilities for the year endedDecember 31, 2013: DerivativeAsset TotalAssets WarrantsissuedDecember 29,2008 WarrantsissuedMay2012 WarrantsissuedAugust 2013 DerivativeLiability TotalLiabilities Balance at beginning of period $1,736 $1,736 $71,581 $2,347,902 $— $548,865 $2,968,348 Issues — — — 19,358,108 19,358,108 Settlements — — — (18,780,167) (10,535,592) (12,828,650) (42,144,409) Revaluation (1,736) (1,736) (54,718) 18,348,018 (5,110,506) 12,279,785 25,462,579 Balance at end of period $— $— $16,863 $1,915,753 $3,712,010 $— $5,644,626 The Company currently does not have derivative instruments to manage its exposure to currency fluctuations or other business risks. The Companyevaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. Allderivative financial instruments are recognized in the balance sheet at fair value.13. Income TaxesThe provision for income taxes consists of the following: Year Ended December 31, 2013 2012 2011 Deferred: Federal $(93,078,760) $4,586,506 $11,367,771 State and local (6,128,198) 493,946 1,437,062 (99,206,958) 5,080,452 12,804,833 Valuation allowance 99,206,958 (5,080,452) (12,804,833) $— $— $— The provision for income taxes varies from the amount determined by applying the U.S. federal statutory rate to income before income taxes as a resultof the following: Year Ended December 31, 2013 2012 2011 U.S. statutory income tax rate 34.0% 34% 34%State and local taxes, net of federal tax benefit (8.9)% 5.2% 4.5%Permanent differences between book and tax and other (169.4)% 14.4% 1.5%Valuation allowance 144.3% (53.6)% (40)%Effective income tax rate — % — % — %Included in permanent differences between book and tax and other in the above table are the impacts of the Section 382 limitation (discussed below) andthe non-deductible mark-to-market activity associated with convertible debt and warrants as well as permanent differences such as nondeductible meals andentertainment. 82The components of the deferred tax asset are as follows: December 31, 2013 2012 Current accruals $1,998,086 $1,753,064 Depreciation and amortization 2,566,979 2,676,884 Deferred compensation 5,421,688 5,332,415 Net operating loss carryovers 28,045,831 127,477,179 Deferred tax assets 38,032,584 137,239,542 Valuation allowance (38,032,584) (137,239,542) Net deferred tax assets $— $— Under Section 382 and 383 of the Internal Revenue Code of 1986, as amended, or the “Code”, if a corporation undergoes an “ownership change,” thecorporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income may be limited. In general, an “ownership change” will occur if there is a cumulative change in our ownership by “5-percent shareholders” thatexceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. Following significant ownership changes during2013, the Company initiated a review of the availability of its U.S. net operating loss carryforwards. As a result of this review, it was determined that a largeportion of the Company’s net operating loss carryovers would expire unused due to the limitation under IRC Section 382. The Company reduced the netoperating loss carryover and corresponding valuation allowance as a result of these limitations as reflected in the net operating loss carryovers in the tableabove. The remaining net operating loss carryforwards following the ownership change have been assigned a full valuation allowance against all deferred taxassets.In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred taxassets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in whichthose temporary differences become deductible. The Company considers projected future taxable income and tax planning strategies in making thisassessment. Based upon the level of historical taxable losses, and projections for future periods over which the deferred tax assets are deductible, the Companydetermined that a 100% valuation allowance of deferred tax assets was appropriate. The valuation allowance for deferred tax assets includes amounts for whichsubsequently recognized tax benefits will be applied directly to contributed capital.Based on the results of the review, discussed above, as of December 31, 2013, we had federal net operating loss carryforwards of approximately $75.8million. The federal net operating loss carryforwards will expire between 2018 and 2033. As of December 31, 2013, we had state net operating losscarryforwards of approximately $2.3 million which will expire at various dates between 2014 and 2033 if not utilized.The Company files income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. As the Company has a federal netoperating loss carryforward from the year ended December 31, 1994 forward, all tax years from 1994 forward are subject to examination. As states havevarying carryforward periods, and the Company has recently entered into additional states, the states are generally subject to examination for the previous 10years or less.The Company recognizes interest accrued, if any, net of tax and penalties, related to unrecognized tax benefits as components of income tax provision asapplicable. As of December 31, 2013 accrued interest and penalties were not material.At December 31, 2013 and 2012, the Company had approximately $0.2 million in reserves for uncertain tax positions. 8314. Net Loss per ShareThe following is a reconciliation of the numerator (net loss) and the denominator (number of shares) used in the basic and diluted earnings per sharecalculations: 2013 2012 2011 Numerator: Numerator for basic EPS $(68,757,589) $(9,238,427) $(32,031,175) Effect of dilutive securities Numerator for diluted EPS $(68,757,589) $(9,238,427) $(32,031,175) Denominator: Denominator for basic EPS—weighted average shares 11,554,566 6,944,928 5,482,627 Effect of dilutive securities Denominator for diluted EPS 11,554,566 6,944,928 5,482,627 Basic EPS $(5.95) $(1.33) $(5.84) Diluted EPS $(5.95) $(1.33) $(5.84) The following table sets forth the number of common shares that were excluded from the computation of diluted earnings per share because theirinclusion would have been anti-dilutive as follows: December 31, 2013 2012 2011 Shares outstanding Restricted shares 6,600 68,543 52,659 Shares issuable upon vesting/exercise of: Options to purchase common stock 188,947 373,899 562,733 Restricted stock units 588,759 529,312 98,820 Warrants 3,021,302 6,099,476 1,038,161 3,805,608 7,071,230 1,752,373 15. Employee Benefit PlanThe Company offers employees the opportunity to participate in a 401(k) plan. Through September 30, 2011, the Company matched employeecontributions dollar for dollar up to 3% of the employee’s salary during the employee’s period of participation. Such employer contributions are discretionaryunder the 401(k) plan. As of October 1, 2011, the Company suspended all matching contributions indefinitely. The Company had no expenses related to theemployee contribution matching program for the year ended December 31, 2013. For the years ended December 31, 2012 and 2011, the Company expensed$8,595, and $395,633, respectively, related to the plan.16.

Subsequent EventsNone. ITEM 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURENone. ITEM 9A.CONTROLS AND PROCEDURES 86Report on Internal Control Over Financial ReportingAs of December 31, 2013, the Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer,evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) promulgated underthe Securities Exchange Act of 1934, as amended (the “Exchange Act”)). Based on such evaluation, the Company’s Chief Executive Officer and ChiefFinancial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective.The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15(d)-15(f) promulgated under the Exchange Act. The Company’s internal control over financial reporting is designed to provide reasonableassurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally acceptedaccounting principles in the United States of America. The Company’s management assessed the effectiveness of our internal control over financial reportingas of December 31, 2013. In making the assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the TreadwayCommission (1992 Framework) in Internal Control—Integrated Framework. Based on our assessment, our management has concluded that our internalcontrol over financial reporting is effective as of December 31, 2013.A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the controlsystem are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be consideredrelative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issuesand instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making canbe faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of somepersons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part upon certainassumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potentialfuture conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or proceduresmay deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.Based on the evaluation of internal control over financial reporting, the Chief Executive Officer and Chief Financial Officer have concluded that therehave been no changes in the Company’s internal controls over financial reporting during the period that is covered by this report that has materially affected oris reasonably likely to materially affect, the Company’s internal control over financial reporting. 87ITEM 9B.OTHER INFORMATIONNone.PART IIICertain information required by Part III is omitted from this Report on Form 10-K since we intend to file our definitive Proxy Statement for our nextAnnual Meeting of Stockholders, pursuant to Regulation 14A of the Securities Exchange Act of 1934, as amended (the “Proxy Statement”), no later thanApril 30, 2014, and certain information to be included in the Proxy Statement is incorporated herein by reference.
