SUMMARY

          The following summary highlights certain significant aspects of our business and the offering, but you should read this entire prospectus, including the information set forth under the heading “Risk Factors,” the financial statements and related notes and the other financial data included herein, before making an investment decision. In this prospectus, unless the context otherwise requires, the terms “we,” “us,” “our” or other similar terms refer to CardioGenesis Corporation and its subsidiaries.

Our Business

           According to the American Heart Association, cardiovascular disease is the leading cause of death and disability in the U.S. We design, develop and distribute laser-based surgical products and disposable fiber-optic accessories for the treatment of advanced cardiovascular disease through transmyocardial revascularization (“TMR”) and percutaneous myocardial revascularization (“PMR”). TMR and PMR are laser-based heart treatments in which channels are made in the heart muscle. Many scientific experts believe these procedures encourage new vessel formation. TMR is performed by a cardiac surgeon through a small incision in the chest under general anesthesia. PMR is performed by a cardiologist in a catheter-based procedure which utilizes local anesthesia.

           We have received CE Mark approval for our TMR and PMR products, which allows us to commercially distribute these products within the European Community. The CE Marking is an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. We have received final approval from the Food and Drug Administration, or FDA, to market and sell our TMR products in the United States for treatment of stable patients with certain types of angina. In July 2001, the FDA recommended against approval of our PMR products for public sale and use in the United States. In July 2003, the FDA agreed to an alternative process in which additional data in support of our application for approval of PMR could be submitted and reviewed by the FDA in an interactive review process. We submitted additional data in August 2003, and the FDA has informed us that they believe this additional data submitted in August 2003 is still not adequate to support approval by the FDA of our PMR system. As part of the interactive review process, we met with the FDA in March 2004. At that time, the FDA was unable to reach a favorable outcome on our application for approval of PMR. We expect to meet with the FDA in the near future in order to clarify any needs for additional clinical data on PMR. At this time, we have determined not to proceed to a Medical Services Resolution Panel review of our PMR application, although that option remains available. There can be no assurance, however, that we will receive a favorable determination from the FDA in the future for our PMR products.

Corporate Information

          We incorporated in California in 1989. On March 17, 1999, we merged with the former CardioGenesis Corporation. Under the terms of the combination, each share of the former CardioGenesis Corporation was converted into 0.8 of a share of our common stock, and the former CardioGenesis Corporation became a wholly owned subsidiary of ours. Our principal executive offices are located at 26632 Towne Center Drive, Suite 320, Foothill Ranch, California 92610 and our telephone number is (714) 649-5000. Our website address is www.cardiogenesis.com. Information contained on our web site does not constitute part of this prospectus.

The Offering

          This prospectus relates to the registration for resale of up to 7,848,838 shares of our common stock by the selling shareholders identified in this prospectus. The prices at which the selling shareholders may sell their shares will be determined by the prevailing market for the shares or in negotiated transactions. See “ Selling Shareholders” on page 41.

Use of Proceeds

          We will not receive any of the proceeds from the sale of the shares of common stock by the selling shareholders. We may receive proceeds from the exercise of the warrants if the selling shareholders opt to pay the exercise price in cash rather than executing a cashless exercise.

Risk Factors

          You should carefully read and consider the information set forth in the section entitled “Risk Factors” beginning on page 2 before investing in our common stock.

1

RISK FACTORS

          An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below, together with all of the other information contained in this prospectus, before you decide to buy our common stock. If any of the following risks actually occur, our business, financial condition, or results of operations could be materially adversely affected. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial also may impair our business. Any adverse effect on our business, financial condition, or results of operations could result in a decline in the trading price of our common stock and the loss of all or part of your investment.

Risks Related to our Business and Industry

          Our ability to maintain current operations is dependent upon sustaining profitable operations or obtaining financing in the future.

          We have incurred significant losses since inception. For example, for the fiscal years 2003, 2002 and 2001 we incurred net losses of $348,000, $530,000 and $10,247,000 respectively. We will have a continuing need for new infusions of cash if we continue to incur losses in the future. We plan to increase our revenues through increased direct sales and marketing efforts on existing products and achieving regulatory approval for other products. If our direct sales and marketing efforts are unsuccessful or we are unable to achieve regulatory approval for our products, we will be unable to significantly increase our revenues. We believe that if we are unable to generate sufficient funds from sales or from debt or equity issuances to maintain our current expenditure rate, it will be necessary to significantly reduce our operations, including our sales and marketing efforts and research and development. If we are required to significantly reduce our operations, our business will be harmed.

          We may be required to seek additional sources of financing, which could include short-term debt, long-term debt or equity. Although in the past we have been successful in obtaining financing, most recently through the private placement of equity securities in January 2004, there is a risk that we may be unsuccessful in obtaining financing in the future on terms acceptable to us and that we will not have sufficient cash to fund our continued operations.

          Our revenues and operating income may be constrained:

          We may fail to obtain required regulatory approvals in the United States to market our PMR laser system.

          The FDA has not approved our PMR laser system for any application in the United States. In July 2001, the FDA Advisory Panel recommended against approval of PMR for public sale and use in the United States. In February 2003, the FDA granted an independent panel review of our pending PMA application for PMR by the Medical Devices Dispute Resolution Panel, or MDDRP. In July 2003, the FDA agreed to an alternative process in which additional data in support of our PMA supplement for PMR could be submitted and reviewed by the FDA in an interactive review process. The data was submitted in August 2003 and the independent panel review by the MDDRP was cancelled. The FDA agreed to reschedule the MDDRP hearing in the future if the dispute cannot be resolved. The FDA has informed us that they believe the data submitted in August 2003 in connection with the interactive review process is still not adequate to support approval by the FDA of our PMR system. As part of the interactive review process, we met with the FDA in March 2004. At that time, the FDA was unable to reach a favorable outcome on our application for approval of PMR. We expect to meet with the FDA in the near future in order to clarify any needs for additional clinical data on PMR. At this time, we have determined not to proceed to a Medical Services Resolution Panel review of our PMR application, although that option remains available. There can be no assurance, however, that we will receive a favorable determination from the FDA in the future.

2

          We will not be able to derive any revenue from the sale of our PMR system in the United States until such time, if any, that the FDA approves the device. Such inability to realize revenue from sales of our PMR device in the United States may have an adverse effect on our results of operations.

          In the future, the FDA could restrict the current uses of our TMR product and thereby restrict our ability to generate revenues.

          We currently derive approximately 99% of our revenues from our TMR product. The FDA has approved this product for sale and use by physicians in the United States. At the request of the FDA, we are currently conducting post-market surveillance of our TMR product. If we should fail to meet the requirements mandated by the FDA or fail to complete our post-market surveillance study in an acceptable time period, the FDA could withdraw its approval for the sale and use of our TMR product by physicians in the United States. Additionally, although we are not aware of any safety concerns during our on-going post-market surveillance of our TMR product, if concerns over the safety of our TMR product were to arise, the FDA could possibly restrict the currently approved uses of our TMR product. In the future, if the FDA were to withdraw its approval or restrict the range of uses for which our TMR product can be used by physicians in the United States, such as restricting TMR’s use with the coronary artery bypass grafting procedure, either outcome could lead to reduced or no sales of our TMR product in the United States and our business could be materially and adversely affected.

          We must comply with FDA manufacturing standards or face fines or other penalties including suspension of production.

          We are required to demonstrate compliance with the FDA’s current good manufacturing practices regulations if we market devices in the United States or manufacture finished devices in the United States. The FDA inspects manufacturing facilities on a regular basis to determine compliance. If we fail to comply with applicable FDA or other regulatory requirements, we can be subject to:

          The impact on us of any such failure to comply would depend on the impact of the remedy imposed on us.

          We may fail to comply with international regulatory requirements and could be subject to regulatory delays, fines or other penalties.

          Regulatory requirements in foreign countries for international sales of medical devices often vary from country to country. In addition, the FDA must approve the export of devices to certain countries. The occurrence and related impact of the following factors would harm our business:

          To market in Europe, a manufacturer must obtain the certifications necessary to affix to its products the CE Marking. The CE Marking is an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. In order to obtain and to maintain a CE Marking, a manufacturer must be in compliance with the appropriate quality assurance provisions of the International Standards Organization and obtain certification of its quality assurance systems by a recognized European Union notified body. However, certain individual countries within Europe require further approval by their national regulatory agencies.

3

          We have completed CE Mark registration for all of our products in accordance with the implementation of various medical device directives in the European Union. Failure to maintain the right to affix the CE Marking or other requisite approvals could prohibit us from selling our products in member countries of the European Union or elsewhere. Any enforcement action by international regulatory authorities with respect to past or future regulatory noncompliance could cause our business to suffer. Noncompliance with international regulatory requirements could result in enforcement action such as prohibitions against us marketing our products in the European Union, which would significantly reduce international revenue.

          We may not be able to successfully market our products if third party reimbursement for the procedures performed with our products is not available for our healthcare provider customers.

          Few individuals are able to pay directly for the costs associated with the use of our products. In the United States, hospitals, physicians and other healthcare providers that purchase medical devices generally rely on third party payors, such as Medicare, to reimburse all or part of the cost of the procedure in which the medical device is being used. Effective July 1, 1999, the Centers for Medicare and Medicaid Services (“CMS”), formerly the Health Care Financing Administration, commenced Medicare coverage for TMR systems for any manufacturer’s TMR procedures. Hospitals and physicians are eligible to receive Medicare reimbursement covering 100% of the costs for TMR procedures. If CMS were to materially reduce or terminate Medicare coverage of TMR procedures, our business and results of operation would be harmed.

          As PMR has not been approved by the FDA, the CMS has not approved reimbursement for PMR. If we obtain FDA approval for PMR in the future and CMS does not provide reimbursement, our ability to successfully market and sell our PMR products will be harmed.

          Even though Medicare beneficiaries appear to account for a majority of all patients treated with the TMR procedure, the remaining patients are beneficiaries of private insurance and private health plans. We have limited experience to date with the acceptability of our TMR procedures for reimbursement by private insurance and private health plans. If private insurance and private health plans do not provide reimbursement, our business will suffer.

          If we obtain the necessary foreign regulatory registrations or approvals for our products, market acceptance in international markets would be dependent, in part, upon the availability of reimbursement within prevailing healthcare payment systems. Reimbursement is a significant factor considered by hospitals in determining whether to acquire new equipment. A hospital is more inclined to purchase new equipment if third-party reimbursement can be obtained. Reimbursement and health care payment systems in international markets vary significantly by country. They include both government sponsored health care and private insurance. Although we expect to seek international reimbursement approvals, any such approvals may not be obtained in a timely manner, if at all. Failure to receive international reimbursement approvals could hurt market acceptance of our TMR and PMR products in the international markets in which such approvals are sought, which would significantly reduce international revenue.

          We may not be able to meet future product demand on a timely basis and may be subject to delays and interruptions to product shipments because we depend on single source third party suppliers and manufacturers.

          We purchase certain critical products and components for lasers and disposable handpieces from single sources. Moreover, we are currently exploring manufacturing outsourcing options for the TMR 2000 laser. In addition, we are vulnerable to delays and interruptions, for reasons out of our control, because we outsource the manufacturing of our products to third parties. We may experience harm to our business if we cannot timely provide lasers to our customers or if our outsourcing suppliers have difficulties supplying our needs for products and components.

          In addition, we do not have long-term supply contracts. As a result, our sources are not obligated to continue to provide these critical products or components to us. Although we have identified alternative suppliers and manufacturers, a lengthy process would be required to qualify them as additional or replacement suppliers or manufacturers. Also, it is possible some of our suppliers or manufacturers could have difficulty meeting our needs if demand for our TMR and PMR laser systems were to increase rapidly or significantly. We believe that we have an adequate supply of lasers to meet our expected demand for the next twelve months and currently expect to have

4

production capacity for our TMR 2000 laser by the fourth quarter of 2004. However, if demand for our TMR 2000 laser is greater than we currently anticipate and there is a delay in obtaining production capacity, unless we are able to obtain lasers originally placed through our loaned laser program and no longer utilized by a hospital, we may not be able to meet the demand for our TMR 2000 laser. In addition, any defect or malfunction in the laser or other products provided by our suppliers and manufacturers could cause delays in regulatory approvals or adversely affect product acceptance. Further, we cannot predict:

          Expansion of our business may put added pressure on our management and operational infrastructure affecting our ability to meet any increased demand for our products and possibly having an adverse effect on our operating results.

          In 2001 we began a restructuring of our business in order, in part, to bring our cost structure more in line with our revenues. As part of this restructuring we significantly reduced our workforce. Growth in our business may place a significant strain on our limited personnel, management, financial systems and other resources. The evolving growth of our business presents numerous risks and challenges, including:

          To accommodate any such growth and compete effectively, we may need to obtain additional funding to improve information systems, procedures and controls and expand, train, motivate and manage our employees, and such funding may not be available in sufficient quantities, if at all. If we are not able to manage these activities and implement these strategies successfully to expand to meet any increased demand, our operating results could suffer.

          Our operating results are expected to fluctuate and quarter-to-quarter comparisons of our results may not indicate future performance.

          Our operating results have fluctuated significantly from quarter-to-quarter and are expected to continue to fluctuate significantly from quarter-to-quarter in future periods. We believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance. Due to the emerging nature of the markets in which we compete, forecasting operating results is difficult and unreliable. It is likely or possible that our operating results for a future quarter will fall below the expectations of public market analysts that may cover our stock and investors. When this occurred in the past, the price of our common stock fell substantially, and if this occurs in the future, the price of our common stock may fall again, perhaps substantially.

          Our common stock is listed on the OTC Bulletin Board which may have an unfavorable impact on our stock price and liquidity.

          Effective April 3, 2003 our common stock was delisted from The Nasdaq SmallCap Market and became quoted on the OTC Bulletin Board on the same day. The OTC Bulletin Board is a significantly more limited market in comparison to the Nasdaq system. The listing of our shares on the OTC Bulletin Board may result in a less liquid

5

market available for existing and potential shareholders to trade shares of our common stock, could ultimately further depress the trading price of our common stock and could have a long-term adverse impact on our ability to raise capital in the future.

          The trading prices of many high technology companies, and in particular medical device companies, have been volatile which may result in large fluctuations in the price of our common stock.

          The stock market has experienced significant price and volume fluctuations that have particularly affected the trading prices of equity securities of many high technology companies. These fluctuations have often been unrelated or disproportionate to the operating performance of many of these companies. Any negative change in the public’s perception of medical device companies could depress our stock price regardless of our operating results.

          The price of our common stock may fluctuate significantly, which may result in losses for investors.

          The market price of our common stock has been and may continue to be volatile. For example, during the 52-week period ended February 13, 2004, the closing prices of our common stock as reported on Nasdaq and on the OTC Bulletin Board ranged from a high of $1.92 per share to a low of $0.24 per share. We expect our stock price to be subject to fluctuations as a result of a variety of factors, including factors beyond our control. These factors include:

          The prices at which our common stock trades will affect our ability to raise capital, which may have an adverse affect on our ability to fund our operations.

          We face competition from products of our competitors which could limit market acceptance of our products and render our products obsolete.

           The market for TMR laser systems is competitive. We currently compete with PLC Systems, a publicly traded company which uses a carbon dioxide, or CO2, laser and an articulated mechanical arm in its TMR products. Edwards Lifesciences, a well known, publicly traded provider of products and technologies to treat cardiovascular disease, has assumed full sales and marketing responsibility in the U.S. for PLC’s TMR Heart Laser 2 System and associated kits pursuant to a co-marketing agreement between the two companies executed in January 2001. Through its significantly greater financial and human resources, including a well-established and extensive sales representative network, we believe Edwards has the potential to market to a greater number of hospitals and doctors that we currently can. If PLC, or any new competitor, is more effective than we are in developing new products and procedures and marketing existing and future products similar to ours, our business will suffer.

          The market for TMR laser systems is characterized by rapid technical innovation. Our current or future competitors may succeed in developing TMR products or procedures that:

6

          If we obtain the FDA’s approval for our PMR laser system, we will face competition for market acceptance and market share for that product. Our ability to compete may depend in significant part on the timing of introduction of competitive products into the market, and will be affected by the pace, relative to competitors, at which we are able to:

          Third party intellectual property rights may limit the development and protection of our intellectual property, which could adversely affect our competitive position.

          Our success is dependent in large part on our ability to:

          The medical device industry has been characterized by extensive litigation regarding patents and other intellectual property rights. Companies in the medical device industry have employed intellectual property litigation to gain a competitive advantage. Certain competitors and potential competitors of ours have obtained United States patents covering technology that could be used for certain TMR and PMR procedures. We do not know if such competitors, potential competitors or others have filed and hold international patents covering other TMR or PMR technology. In addition, international patents may not be interpreted the same as any counterpart United States patents.

          While we periodically review the scope of our patents and other relevant patents of which we are aware, the question of patent infringement involves complex legal and factual issues. Any conclusion regarding infringement may not be consistent with the resolution of any such issues by a court.

          Costly litigation may be necessary to protect our intellectual property rights.

          We may have to engage in time consuming and costly litigation to protect our intellectual property rights or to determine the proprietary rights of others. In addition, we may become subject to patent infringement claims or litigation, or interference proceedings declared by the United States Patent and Trademark Office to determine the priority of inventions.

          Defending and prosecuting intellectual property suits, United States Patent and Trademark Office interference proceedings and related legal and administrative proceedings are both costly and time-consuming. We may be required to litigate further to:

          Any litigation or interference proceedings will result in substantial expense and significant diversion of effort by technical and management personnel. If the results of such litigation or interference proceedings are adverse to us, then the results may:

7

     Although patent and intellectual property disputes regarding medical devices are often settled through licensing and similar arrangements, costs associated with such arrangements may be substantial and could include ongoing royalties. Furthermore, we may not be able to obtain the necessary licenses on satisfactory terms, if at all.

     Adverse determinations in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent us from manufacturing and selling our products. This would harm our business.

     The United States patent laws have been amended to exempt physicians, other health care professionals, and affiliated entities from infringement liability for medical and surgical procedures performed on patients. We are not able to predict if this exemption will materially affect our ability to protect our proprietary methods and procedures.

     We rely on patent and trade secret laws which are complex and may be difficult to enforce.

     The validity and breadth of claims in medical technology patents involve complex legal and factual questions and, therefore, may be highly uncertain. Issued patent or patents based on pending patent applications or any future patent application may not exclude competitors or may not provide a competitive advantage to us. In addition, patents issued or licensed to us may not be held valid if subsequently challenged and others may claim rights in or ownership of such patents.

     Furthermore, we cannot assure you that our competitors:

          Because patent applications in the United States were historically maintained in secrecy until the patents are issued, we cannot be certain that:

          We may suffer losses from product liability claims if our products cause harm to patients.

          We are exposed to potential product liability claims and product recalls. These risks are inherent in the design, development, manufacture and marketing of medical devices. We could be subject to product liability claims if the use of our TMR or PMR laser systems is alleged to have caused adverse effects on a patient or such products are believed to be defective. Our products are designed to be used in life-threatening situations where there is a high risk of serious injury or death. We are not aware of any material side effects or adverse events arising from the use of our TMR product. Though we are in the process of responding to the FDA’s Circulatory Devices Panel’s recent recommendation against approval of our PMR product because of concerns over the safety of the device and the data regarding adverse events in the clinical trials, we believe there are no material side effects or adverse events arising from the use of our PMR product. When being clinically investigated, it is not uncommon for new surgical or interventional procedures to result in a higher rate of complications in the treated population of patients as opposed to those reported in the control group. In light of this, we believe that the difference in the rates of complications between the treated groups and the control groups in the clinical trials for our PMR product are not statistically significant, which is why we believe that there are no material side effects or material adverse events arising from the use of our PMR product.

8

          Any regulatory clearance for commercial sale of these products will not remove these risks. Any failure to comply with the FDA’s good manufacturing practices or other regulations could hurt our ability to defend against product liability lawsuits.

          Our insurance may be insufficient to cover product liability claims against us.

          Our product liability insurance may not be adequate for any future product liability problems or continue to be available on commercially reasonable terms, or at all.

          If we were held liable for a product liability claim or series of claims in excess of our insurance coverage, such liability could harm our business and financial condition. We maintain insurance against product liability claims in the amount of $10 million per occurrence and $10 million in the aggregate.

          We may require increased product liability coverage as sales of approved products increase and as additional products are commercialized. Product liability insurance is expensive and in the future may not be available on acceptable terms, if at all.

          We depend heavily on key personnel, and turnover of key employees and senior management could harm our business.

          Our future business and results of operations depend in significant part upon the continued contributions of our key technical and senior management personnel. They also depend in significant part upon our ability to attract and retain additional qualified management, technical, marketing and sales and support personnel for our operations. If we lose a key employee or if a key employee fails to perform in his or her current position, or if we are not able to attract and retain skilled employees as needed, our business could suffer. Significant turnover in our senior management could significantly deplete our institutional knowledge held by our existing senior management team. For example, in November 2003, our employment relationship with Darrell Eckstein, our former President, Chief Operating Officer, Acting Chief Financial Officer, Chief Accounting Officer, Treasurer and Secretary was terminated. We depend on the skills and abilities of these key employees in managing the manufacturing, technical, marketing and sales aspects of our business, any part of which could be harmed by further turnover.

          We sell our products internationally which subjects us to specific risks of transacting business in foreign countries.

          In future quarters, international sales may become a significant portion of our revenue if our products become more widely used outside of the United States. Our international revenue is subject to the following risks, the occurrence of any of which could harm our business:

Risks Relating to this Offering

This offering and future sales of our common stock could lower our stock price.

The sale of our common stock by our shareholders in this offering could cause the market price of our common stock to decline. In addition, if our shareholders sell substantial amounts of our common stock, including shares issuable upon exercise of options or warrants, in the public market following this offering, the market price of our common stock could decline. If these sales were to occur, we may also find it more difficult to sell equity or equity-related securities in the future at a time and price that we deem appropriate and desirable.

In the future, we may issue additional shares in public or private offerings. We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of our common stock would have on the market price of our common stock.

Provisions of our certificate of incorporation as well as our rights agreement could discourage potential acquisition proposals and could deter or prevent a change of control.

Our articles of incorporation authorize our board of directors, subject to any limitations prescribed by law, to issue shares of preferred stock in one or more series without shareholder approval. On August 17, 2001 we adopted a shareholder rights plan, as amended, and under the rights plan, our board of directors declared a dividend distribution of

10

one right for each outstanding share of common stock to shareholders of record at the close of business on August 30, 2001. Pursuant to the Rights Agreement, in the event (a) any person or group acquires 15% or more of our then outstanding shares of voting stock (or 21% or more of our then outstanding shares of voting stock in the case of State of Wisconsin Investment Board), (b) a tender offer or exchange offer is commenced that would result in a person or group acquiring 15% or more of our then outstanding voting stock, (c) we are acquired in a merger or other business combination in which we are not the surviving corporation or (d) 50% or more of our consolidated assets or earning power are sold, then the holders of our common stock are entitled to exercise the rights under the Rights Plan, which include, based on the type of event which has occurred, (i) rights to purchase preferred shares from us, (ii) rights to purchase common shares from us having a value twice that of the underlying exercise price, and (iii) rights to acquire common stock of the surviving corporation or purchaser having a market value of twice that of the exercise price. The rights expire on August 17, 2011, and may be redeemed prior thereto at $.001 per right under certain circumstances. The Board’s ability to issue preferred stock without shareholder approval while providing desirable flexibility in connection with financings, acquisitions and other corporate purposes, and the existence of the rights plan might discourage, delay or prevent a change in the ownership of our company or a change in our management. In addition, these provisions could limit the price that investors would be willing to pay in the future for shares of our common stock.

          CardioGenesis Corporation, incorporated in California in 1989, designs, develops and distributes laser-based surgical products and disposable fiber-optic accessories for the treatment of advanced cardiovascular disease through transmyocardial revascularization (“TMR”) and percutaneous transluminal myocardial revascularization (“PMR”). TMR and PMR are recent laser-based heart treatments in which channels are made in the heart muscle. Many scientific experts believe these procedures encourage new vessel formation, or angiogenesis. TMR is performed by a cardiac surgeon through a small incision in the chest under general anesthesia. PMR is performed by a cardiologist in a catheter-based procedure which utilizes local anesthesia. Clinical studies have demonstrated a significant reduction in angina and increase in exercise duration in patients treated with TMR or PMR plus medications, when compared with patients who received medications alone.

           We received CE Mark approval for our TMR system in May 1997 and our PMR system in April 1998, which allows us to commercially distribute these products within the European Community. The CE Marking is an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. On February 11, 1999, we received final approval from the Food and Drug Administration (“FDA”) for our TMR products for treatment of stable patients with certain types of angina. Effective July 1, 1999, Centers for Medicare and Medicaid Services (“CMS”), formerly known as the Health Care Financial Administration (“HCFA”), began to provide Medicare coverage for any manufacturer’s TMR procedures. As a result, hospitals and physicians are eligible to receive Medicare reimbursement for TMR equipment and procedures for Medicare patients.

           We have completed pivotal clinical trials involving PMR, and study results were submitted to the FDA in a Pre Market Approval, or PMA application, in December 1999 along with subsequent amendments. In July 2001, the FDA Advisory Panel recommended against approval of PMR for public sale and use in the United States. In February 2003, the FDA granted an independent panel review of our pending PMA application for PMR by the Medical Devices Dispute Resolution Panel, or MDDRP. In July 2003, the FDA agreed to an alternative process in which additional data in support of our PMA supplement for PMR could be submitted and reviewed by the FDA in an interactive review process. The data was submitted in August 2003 and the independent panel review by the MDDRP was cancelled. The FDA agreed to reschedule the MDDRP hearing in the future if the dispute cannot be resolved. The FDA has informed us that they believe the data submitted in August 2003 in connection with the interactive review process is still not adequate to support approval by the FDA of our PMR system. As part of the interactive review process, we met with the FDA in March 2004. At that time, the FDA was unable to reach a favorable outcome on our application for approval of PMR. We expect to meet with the FDA in the near future in order to clarify any needs for additional clinical data on PMR. At this time, we have determined not to proceed to a Medical Services Resolution Panel review of our PMR application, although that option remains available. There can be no assurance, however, that we will receive a favorable determination from the FDA in the future.

          On March 17, 1999, we merged with the former CardioGenesis Corporation. Under the terms of the combination, each share of the former CardioGenesis common stock was converted into 0.8 of a share of our common stock, and the former CardioGenesis has become a wholly owned subsidiary of ours. As a result of the transaction, our outstanding shares increased by approximately 9.9 million shares. The transaction was structured to qualify as a tax-free reorganization and has been accounted for as a pooling of interests. Accordingly, the financial information included in this report has been restated as if the combined entity existed for the 1999 period prior to the merger.

Background

          According to the American Heart Association, cardiovascular disease is the leading cause of death and disability in the U.S. Coronary artery disease is the principal form of cardiovascular disease and is characterized by a progressive narrowing of the coronary arteries which supply blood to the heart. This narrowing process is usually due to atherosclerosis, which is the buildup of fatty deposits, or plaque, on the inner lining of the arteries. Coronary artery disease reduces the available supply of oxygenated blood to the heart muscle, potentially resulting in severe chest pain known as angina, as well as damage to the heart. Typically, the condition worsens over time and often leads to heart attack and/or death.

14

          Based on standards promulgated by the Canadian Heart Association, angina is typically classified into four classes, ranging from Class 1, in which angina pain results only from strenuous exertion, to the most severe, Class 4, in which the patient is unable to conduct any physical activity without angina and angina may be present even at rest. The American Heart Association estimates that more than six million Americans experience angina symptoms.

          The primary therapeutic options for treatment of coronary artery disease are drug therapy, balloon angioplasty also known as percutaneous transluminal coronary angioplasty or (“PTCA”), other interventional techniques which augment or replace PTCA such as stent placement and atherectomy, and coronary artery bypass grafting (“CABG”). The objective of each of these approaches is to increase blood flow through the coronary arteries to the heart.

          Drug therapy may be effective for mild cases of coronary artery disease and angina either through medical effects on the arteries that improve blood flow without reducing the plaque or by decreasing the rate of formation of additional plaque (e.g., by reducing blood levels of cholesterol). Because of the progressive nature of the disease, however, many patients with angina ultimately undergo either PTCA or CABG.

          Introduced in the early 1980s, PTCA is a less-invasive alternative to CABG in which a balloon-tipped catheter is inserted into an artery, typically near the groin, and guided to the areas of blockage in the coronary arteries. The balloon is then inflated and deflated at each blockage site, thereby rupturing the blockage and stretching the vessel. Although the procedure is usually successful in widening the blocked channel, the artery often re-narrows within six months of the procedure, a process called “restenosis,” often necessitating a repeat procedure. A variety of techniques for use in conjunction with PTCA have been developed in an attempt to reduce the frequency of restenosis, including stent placement and atherectomy. Stents are small metal frames delivered to the area of blockage using a balloon catheter and deployed or expanded within the coronary artery. The stent is a permanent implant intended to keep the channel open. Atherectomy is a means of using mechanical, laser or other techniques at the tip of a catheter to cut or grind away plaque.

          CABG is an open chest procedure developed in the 1960s in which conduit vessels are taken from elsewhere in the body and grafted to the blocked coronary arteries so that blood can bypass the blockage. CABG typically requires the use of a heart-lung bypass machine to render the heart inactive (to allow the surgeon to operate on a still, relatively bloodless heart) and involves prolonged hospitalization and patient recovery periods. Accordingly, it is generally reserved for patients with severe cases of coronary artery disease or those who have previously failed to receive adequate relief of their symptoms from PTCA or related techniques. Most bypass grafts fail within one to fifteen years following the procedure. Repeating the surgery (“re-do bypass surgery”) is possible, but is made more difficult because of scar tissue and adhesions that typically form as a result of the first operation. Moreover, for many patients CABG is inadvisable for various reasons, such as the severity of the patient’s overall condition, the extent of coronary artery disease or the small size of the blocked arteries.

          When these treatment options are exhausted, the patient is left with no viable surgical or interventional alternative other than, in limited cases, heart transplantation. Without a viable surgical alternative, the patient is generally managed with drug therapy, often with significant lifestyle limitations. TMR, which bears the CE Marking and has received FDA approval, and PMR, which bears the CE Marking and for which we are continuing to pursue FDA approval for use in the U.S., offer potential relief to a large population of patients with severe cardiovascular disease.

The TMR and PMR Procedures

          TMR is a surgical procedure performed on the beating or non-beating heart, in which a laser device is used to create pathways through the myocardium directly into the heart chamber. The pathways are intended to supply blood to ischemic, or oxygen-deprived regions of the myocardium and reduce angina in the patient. TMR can be performed using open chest surgery or minimally invasive surgery through a small incision between the ribs. TMR offers end-stage cardiac patients who have regions of ischemia not amenable to PTCA or CABG a means to alleviate their symptoms and improve their quality of life. We have received FDA approval for U.S. commercial distribution of our TMR laser system for treatment of stable patients with angina (Canadian Cardiovascular Society Class 4) refractory to medical treatment and secondary to objectively demonstrated coronary artery atherosclerosis and with a region of the myocardium with reversible ischemia not amenable to direct coronary revascularization.

15

          PMR is an interventional procedure performed by a cardiologist. PMR is based upon the same principles as TMR, but the procedure is much less invasive. The procedure is performed under local anesthesia and the patient is treated through a catheter inserted in the femoral artery at the top of the leg. A laser transmitting catheter is threaded up into the heart chamber, where channels are created in the inner portion of the myocardium (i.e. heart muscle). PMR has received the CE Marking approving its use within the European Union. See our discussion below under the caption “Regulatory Status,” for the status of our PMA application with the FDA seeking approval of PMR for public sale and use in the United States.

Business Strategy

          Our objective is to become a recognized leader in the field of myocardial revascularization, with TMR and PMR established as well-known and acceptable therapies. Our strategies to achieve this goal are as follows:

          • Expand Market for our Products. We are seeking to expand market awareness of our products among leaders in the cardiovascular field, the referring physician community and the targeted patient population. In connection with the FDA approved TMR product, we have prioritized our efforts in the U.S. on the top 600 hospitals that perform the greatest number of cardiovascular procedures. We also currently intend to expand our marketing efforts in Europe and to the rest of the world through the establishment and expansion of direct international sales and support organizations and third party distributors and agents. In addition, we have developed a comprehensive training program to assist physicians in acquiring the expertise necessary to utilize our TMR and PMR products and procedures.

           • Demonstrate Clinical Utility of PMR. We are seeking to demonstrate the clinical safety and effectiveness of PMR. We have completed a pivotal clinical trial regarding PMR, and the study results were submitted to the FDA in a PMA application in December 1999, along with subsequent supplements. As discussed below under the caption “Regulatory Status,” the FDA Advisory Panel recommended against approval of PMR for public sale and use in the United States and further informed us that they believe the data submitted in August 2003 in connection with the interactive review process is still not adequate to support approval by the FDA of our PMR system. As part of the interactive review process, we met with the FDA in March 2004. At that time, the FDA was unable to reach a favorable outcome on our application for approval of PMR. We expect to meet with the FDA in the near future in order to clarify any needs for additional clinical data on PMR. At this time, we have determined not to proceed to a Medical Services Resolution Panel review of our PMR application, although that option remains available. We cannot assure you, however, that we will receive a favorable determination from the FDA in the future.

          • Leverage Proprietary Technology. We believe that our significant expertise in laser and catheter-based systems for cardiovascular disease and the proprietary technologies we have developed are important factors in our efforts to demonstrate the safety and effectiveness of our TMR and PMR procedures. We are seeking to develop additional proprietary technologies for TMR, PMR and related procedures. We have over 100 foreign and U.S. patents or allowed patent applications and more than 200 U.S. and foreign patent applications pending relating to various aspects of TMR, PMR and other cardiovascular therapies.

Products and Technology

     TMR System

          Our TMR system consists of a holmium laser console and a line of fiber-optic, laser-based surgical tools. Each surgical tool utilizes an optical fiber assembly to deliver laser energy from the source laser base unit to the distal tip of the surgical handpiece or PMR catheter. The compact base unit occupies a small amount of operating room floor space, operates on standard 220-volt power supply, and is light enough to move within the operating room or among operating rooms in order to use operating room space efficiently. Moreover, the flexible fiberoptic assembly used to deliver the laser energy to the patient enables ready access to the patient and to various sites within the heart.

          Our TMR system and related surgical procedures are designed to be used without the requirement of the external systems utilized with certain competitive TMR systems. For example, our TMR 2000 system does not require electrocardiogram synchronization, which monitors the electrical output of the heart and times the use of the laser to minimize electrical disruption of the heart, or transesophageal echocardiography, which tests each

16

application of the laser to the myocardium during the TMR procedure to determine if the pathway has penetrated through the myocardium into the heart chamber.

          Holmium Laser. Our TMR 2000 laser base unit generates 2.1 micron wavelength laser light by photoelectric excitation of a solid state holmium crystal. The holmium laser, because it uses a solid state crystal as its source, is compact, reliable and requires minimal maintenance.

          SoloGrip. The single use SoloGrip handpiece system contains multiple, fine fiber-optic strands in a one millimeter diameter bundle. The flexible fiber optic delivery system combined with the ergonomic handpiece provides access for treating all regions of the left ventricle.

          The SoloGrip fiber-optic delivery system has an easy to install connector that screws into the laser base unit, and the device is pre-calibrated in the factory so it requires no special preparation.

     PMR System

          Our PMR system is currently sold only outside the United States. The PMR system consists of the PMR Laser and ECG Monitor.

          PMR Laser. Our holmium laser base unit generates 2.1 micron wavelength laser light in the mid-infrared spectrum. It provides a reliable source for laser energy with low maintenance.

          Axcis Catheter System. Our Axcis catheter system is an over-the-wire system that consists of two components, the Axcis laser catheter and Axcis aligning catheter. Our Axcis catheter system is designed to provide controlled navigation and access to target regions of the left ventricle. The coaxial Axcis laser catheter has an independent, extendible lens with radiopaque lens markers which show the location and orientation of the tip for optimal contact with the ventricle wall. The Axcis laser catheter also has nitinol petals at the laser-lens tip which are designed for safe penetration of the endocardium and to provide depth control.

Regulatory Status

          United States. On February 11, 1999, we received approval from the FDA for use of our TMR 2000 laser console and SoloGrip handpiece for treatment of stable patients with angina (Canadian Cardiovascular Society Class 4) refractory to other medical treatments and secondary to objectively demonstrated coronary artery atherosclerosis and with a region of the myocardium with reversible ischemia not amenable to direct coronary revascularization.

          We have completed pivotal clinical trials involving PMR and study results were submitted to the FDA in a PMA application in December 1999 along with subsequent amendments. The PMR study compares PMR to conventional medical therapy in patients with no option for other treatment. In July 2001, the FDA Advisory Panel recommended against approval of PMR for public sale and use in the United States. In July 2003, the FDA agreed to an alternative process in which additional data in support of our PMA supplement for PMR could be submitted and reviewed by the FDA in an interactive review process. The data was submitted in August 2003 and the independent panel review by the MDDRP was cancelled. The FDA agreed to reschedule the MDDRP hearing in the future if the dispute cannot be resolved. The FDA has informed us that they believe the data submitted in August 2003 in connection with the interactive review process is still not adequate to support approval by the FDA of our PMR system. We are currently scheduled to meet with the FDA in March 2004 as part of the ongoing interactive review process. We cannot assure you, however, that we will receive a favorable determination from the FDA.

          European Union. We have obtained approval to affix the CE Marking to substantially all of our products, which enables us to commercially distribute our TMR and PMR products throughout the European Community.

Sales and Marketing

          We have received FDA approval for our surgical TMR laser system. In July 1999, the Centers for Medicare and Medicaid Services announced its coverage policy for TMR equipment and procedures. We are

17

promoting market awareness of our approved surgical products among opinion leaders in the cardiovascular field and are recruiting physicians and hospitals to use our TMR products.

          In the United States, we currently offer a laser base unit at a current end user list price of $355,000 per unit, and the disposable TMR handpiece (at least one of which must be used with each TMR procedure) at an end user unit list price of $3,300. In addition to sales of lasers to hospitals outright, in an effort to accelerate market adoption of the TMR procedure, we developed a program in which we loan lasers to hospitals in return for the hospital purchasing a minimum number of handpieces at a premium over the list price.

          Internationally, we sell our TMR and PMR products through a direct sales and support organization and through distributors and agents. We currently intend to expand our marketing efforts in Europe and to the rest of the world through the establishment and expansion of direct international sales and support organizations and third party distributors and agents. We can not assure you, however, that we will be successful in increasing our international sales.

          We have developed, in conjunction with several major hospitals using our TMR or PMR products, a training program to assist physicians in acquiring the expertise necessary to utilize our products and procedures. This program includes a comprehensive one-day course including didactic training and hands-on performance of TMR or PMR in vivo. To date over 1,200 cardiothoracic surgeons have been trained on the CardioGenesis TMR system.

          We exhibit our products at major meetings of cardiovascular medicine practitioners. Evaluators of our products have made presentations at meetings around the world, describing their results. Abstracts and articles have been published in peer-reviewed publications and industry journals to present the results of our clinical trials.

Research and Development

          We believe that streamlining our research efforts and product offerings is essential to our ability to stimulate growth and maintain our market leadership position. Our ongoing research and product development efforts are focused on the development of new and enhanced lasers and fiber-optic handpieces for TMR and PMR applications.

          We believe our future success will depend, in part, upon the success of our research and development programs. There can be no assurance that we will realize financial benefit from these efforts or that products or technologies developed by others will not render our products or technologies obsolete or non-competitive.

Manufacturing

          We outsource the manufacturing and assembly of our TMR and PMR handpiece systems to a single contract manufacturer. We believe that we have an adequate supply of lasers to meet our expected demand for the next twelve months. We are currently exploring manufacturing outsourcing options for the TMR 2000 laser and currently expect to have production capacity by the fourth quarter of 2004. The PMR laser system is provided to us under a manufacturing agreement with a laser manufacturing company.

          Certain components of our laser units and fiber-optic handpieces are generally acquired from multiple sources. Other laser and fiber-optic components and subassemblies are purchased from single sources. Although we have identified alternative vendors, the qualification of additional or replacement vendors for certain components or services is a lengthy process. Any significant supply interruption would have a material adverse effect on the ability to manufacture our products and, therefore, would harm our business. We intend to continue to qualify multiple sources for components that are presently single sourced.

Competition

     We expect that the market for TMR and PMR, which is currently in the early stages of development, will be competitive. At this point in time, we believe that our only competitor is PLC Systems, Inc. (“PLC”) which markets FDA-approved TMR products in the U.S. and abroad. Other competitors may also enter the market,

18

including large companies in the laser and cardiac surgery markets. Many of these companies have or may have significantly greater financial, research and development, marketing and other resources than we do.

           PLC is a publicly traded corporation which uses a CO2 laser and an articulated mechanical arm in its TMR products. PLC obtained a Pre Market Approval for TMR in 1998. PLC has received the CE Marking, which allows sales of its products commercially in all European Union countries. PLC has been issued patents for its apparatus and methods for TMR. Edwards Lifesciences, a well known, publicly traded provider of products and technologies to treat cardiovascular disease, has assumed full sales and marketing responsibility in the U.S. for PLC’s TMR Heart Laser 2 System and associated kits pursuant to a co-marketing agreement between the two companies executed in January 2001. Through its significantly greater financial and human resources, including a well-established and extensive sales representative network, we believe Edwards has the potential to market to a greater number of hospitals and doctors than we currently can.

          We believe that the factors which will be critical to market success include: the timing of receipt of requisite regulatory approvals, effectiveness and ease of use of the TMR products and applications, breadth of product line, system reliability, brand name recognition, effectiveness of distribution channels and cost of capital equipment and disposable devices.

          TMR and PMR also compete with other methods for the treatment of cardiovascular disease, including drug therapy, PTCA and CABG. Even with the FDA approval of our TMR system in patients for whom other cardiovascular treatments are not likely to provide relief, and when used in conjunction with other treatments, we cannot assure you that our TMR or PMR products will be accepted by cardiovascular professionals. Moreover, technological advances in other therapies for cardiovascular disease such as pharmaceuticals or future innovations in cardiac surgery techniques could make such other therapies more effective or lower in cost than our TMR procedure and could render our technology obsolete. We cannot assure you that physicians will use our TMR procedure to replace or supplement established treatments, or that our TMR procedure will be competitive with current or future technologies. Such competition could harm our business.

          Our TMR laser system and any other product developed by us that gains regulatory approval will face competition for market acceptance and market share. An important factor in such competition may be the timing of market introduction of competitive products. Accordingly, the relative pace at which we can develop products, complete clinical testing, achieve regulatory approval, gain reimbursement acceptance and supply commercial quantities of the product to the market are important competitive factors. In the event a competitor is able to obtain a PMA for its products prior to our doing so, we may not be able to compete successfully. We may not be able to compete successfully against current and future competitors even if we obtain a PMA prior to our competitors.

Government Regulation

          Laser-based surgical products and disposable fiber-optic accessories for the treatment of advanced cardiovascular disease through TMR are considered medical devices, and as such are subject to regulation in the U.S. by the FDA and outside the U.S. by comparable international regulatory agencies. Our devices require the rigorous PMA process for approval to market the product in the U.S. and must bear the CE Marking for commercial distribution in the European Community.

          To obtain a Pre Market Approval (“PMA”) for a medical device, we must file a PMA application that includes clinical data and the results of preclinical and other testing sufficient to show that there is a reasonable assurance of safety and effectiveness of the product for its intended use. To begin a clinical study, an Investigational Device Exemption (“IDE”) must be obtained and the study must be conducted in accordance with FDA regulations. An IDE application must contain preclinical test data demonstrating the safety of the product for human investigational use, information on manufacturing processes and procedures, and proposed clinical protocols. If the FDA clears the IDE application, human clinical trials may begin. The results obtained from these trials are accumulated and, if satisfactory, are submitted to the FDA in support of a PMA application. Prior to U.S. commercial distribution, premarket approval is required from the FDA. In addition to the results of clinical trials, the PMA application must include other information relevant to the safety and effectiveness of the device, a description of the facilities and controls used in the manufacturing of the device, and proposed labeling. By law, the FDA has 180 days to review a PMA application. While the FDA has responded to PMA applications within the allotted time

19

frame, reviews more often occur over a significantly longer period and may include requests for additional information or extensive additional trials. There can be no assurance that we will not be required to conduct additional trials which may result in substantial costs and delays, nor can there be any assurance that a PMA will be obtained for each product in a timely manner, if at all. In addition, changes in existing regulations or the adoption of new regulations or policies could prevent or delay regulatory approval of our products. Furthermore, even if a PMA is granted, subsequent modifications of the approved device or the manufacturing process may require a supplemental PMA or the submission of a new PMA which could require substantial additional clinical efficacy data and FDA review. After the FDA accepts a PMA application for filing, and after FDA review of the application, a public meeting is frequently held before an FDA advisory panel in which the PMA is reviewed and discussed. The panel then issues a favorable or unfavorable recommendation to the FDA or recommends approval with conditions. Although the FDA is not bound by the panel’s recommendations, it tends to give such recommendations significant weight. In February 1999, we received a PMA for our TMR laser system for use in certain indications. As discussed above under the caption “Regulatory Status,” the FDA Advisory Panel recommended against approval of PMR for public sale and use in the United States and further informed us that they believe the data submitted in August 2003 in connection with the interactive review process is still not adequate to support approval by the FDA of our PMR system. As part of the interactive review process, we met with the FDA in March 2004. At that time, the FDA was unable to reach a favorable outcome on our application for approval of PMR. We expect to meet with the FDA in the near future in order to clarify any needs for additional clinical data on PMR. At this time, we have determined not to proceed to a Medical Services Resolution Panel review of our PMR application, although that option remains available. We cannot assure you, however, that we will receive a favorable determination from the FDA in the future.

          Products manufactured or distributed by us pursuant to a PMA will be subject to pervasive and continuing regulation by the FDA, including, among other things, postmarket surveillance and adverse event reporting requirements. Failure to comply with applicable regulatory requirements can result in, among other things, warning letters, fines, suspensions or delays of approvals, seizures or recalls of products, operating restrictions or criminal prosecutions. The Federal Food, Drug and Cosmetic Act requires us to manufacture our products in registered establishments and in accordance with Good Manufacturing Practices (“GMP”) regulations and to list our devices with the FDA. Furthermore, as a condition to receipt of a PMA, our facilities, procedures and practices will be subject to additional pre-approval GMP inspections and thereafter to ongoing, periodic GMP inspections by the FDA. These GMP regulations impose certain procedural and documentation requirements upon us with respect to manufacturing and quality assurance activities. Labeling and promotional activities are subject to scrutiny by the FDA. Current FDA enforcement policy prohibits the marketing of approved medical devices for unapproved uses. Changes in existing regulatory requirements or adoption of new requirements could harm our business. We may be required to incur significant costs to comply with laws and regulations in the future and current or future laws and regulations may harm our business.

          We are also regulated by the FDA under the Radiation Control for Health and Safety Act, which requires laser products to comply with performance standards, including design and operation requirements, and manufacturers to certify in product labeling and in reports to the FDA that our products comply with all such standards. The law also requires laser manufacturers to file new product and annual reports, maintain manufacturing, testing and sales records, and report product defects. Various warning labels must be affixed and certain protective devices installed, depending on the class of the product. In addition, we are subject to California regulations governing the manufacture of medical devices, including an annual licensing requirement. Our facilities are subject to ongoing, periodic inspections by the FDA and California regulatory authorities.

          Sales, manufacturing and further development of our TMR and PMR systems also may be subject to additional federal regulations pertaining to export controls and environmental and worker protection, as well as to state and local health, safety and other regulations that vary by locality and which may require obtaining additional permits. We cannot predict the impact of these regulations on our business.

          Sales of medical devices outside of the U.S. are subject to foreign regulatory requirements that vary widely by country. In addition, the FDA must approve the export of devices to certain countries. To market in Europe, a manufacturer must obtain the certifications necessary to affix to its products the CE Marking. The CE Marking is an international symbol of adherence to quality assurance standards and compliance with applicable European medical device directives. In order to obtain and to maintain a CE Marking, a manufacturer must be in compliance with appropriate ISO 9001 standards and obtain certification of its quality assurance systems by a recognized European Union notified body. However, certain individual countries within Europe require further approval by their national regulatory agencies. We have achieved International Standards Organization and European Union certification for

20

our manufacturing facility. In addition, we have completed CE mark registration for all of our products in accordance with the implementation of various medical device directives in the European Union. Failure to maintain the right to affix the CE Marking or other requisite approvals could prohibit us from selling our TMR and PMR products in member countries of the European Union or elsewhere.

Intellectual Property Matters

          Our success depends, in part, on our ability to obtain patent protection for our products, preserve our trade secrets, and operate without infringing the proprietary rights of others. Our policy is to seek to protect our proprietary position by, among other methods, filing U.S. and foreign patent applications related to our technology, inventions and improvements that are important to the development of our business. We have over 100 U.S. and foreign patents or allowed patent applications and more than 200 U.S. and foreign patent applications pending relating to various aspects of TMR, PMR and other cardiovascular therapies. Our patents or patent applications may be challenged, invalidated or circumvented in the future or the rights granted may not provide a competitive advantage. We intend to vigorously protect and defend our intellectual property. We do not know if patent protection will continue to be available for surgical methods in the future. Costly and time-consuming litigation brought by us may be necessary to enforce our patents and to protect our trade secrets and know-how, or to determine the enforceability, scope and validity of the proprietary rights of others.

          We also rely upon trade secrets, technical know-how and continuing technological innovation to develop and maintain our competitive position. We typically require our employees, consultants and advisors to execute confidentiality and assignment of inventions agreements in connection with their employment, consulting, or advisory relationships with us. If any of these agreements are breached, we may not have adequate remedies available thereunder to protect our intellectual property or we may incur substantial expenses enforcing our rights. Furthermore, our competitors may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our proprietary technology, or we may not be able to meaningfully protect our rights in unpatented proprietary technology.

          The medical device industry in general, and the industry segment that includes products for the treatment of cardiovascular disease in particular, have been characterized by substantial competition and litigation regarding patent and other intellectual property rights. In this regard, our competitors have been issued a number of patents related to TMR and PMR. There can be no assurance that claims or proceedings will not be initiated against us by competitors or other third parties in the future. In particular, the introduction in the United States market of our PMR technology, should that occur, may create new exposures to claims of infringement of third party patents. Any such claims in the future, regardless of whether they have merit, could be time-consuming and expensive to respond to and could divert the attention of our technical and management personnel. We may be involved in litigation to defend against claims of our infringement, to enforce our patents, or to protect our trade secrets. If any relevant claims of third party patents are upheld as valid and enforceable in any litigation or administrative proceeding, we could be prevented from practicing the subject matter claimed in such patents, or we could be required to obtain licenses from the patent owners of each such patent or to redesign our products or processes to avoid infringement.

          We cannot assure that our current and potential competitors and other third parties have not filed or in the future will not file patent applications for, or have not received or in the future will not receive, patents or obtain additional proprietary rights that will prevent, limit or interfere with our ability to make, use or sell our products either in the U.S. or internationally. In the event we were to require licenses to patents issued to third parties, such licenses may not be available or, if available, may not be available on terms acceptable to us. In addition, we cannot assure you that we would be successful in any attempt to redesign our products or processes to avoid infringement or that any such redesign could be accomplished in a cost-effective manner. Accordingly, an adverse determination in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent us from manufacturing and selling our products, which would harm our business.

Third Party Reimbursement

          We expect that sales volumes and prices of our products will continue to depend significantly on the availability of reimbursement for surgical procedures using our products from third party payors such as governmental programs, private insurance and private health plans. Reimbursement is a significant factor considered

21

by hospitals in determining whether to acquire new equipment. Reimbursement rates from third party payors vary depending on the third party payor, the procedure performed and other factors. Moreover, third party payors, including government programs, private insurance and private health plans, have in recent years been instituting increasing cost containment measures designed to limit payments made to healthcare providers by, among other measures, reducing reimbursement rates, limiting services covered, negotiating prospective or discounted contract pricing and carefully reviewing and increasingly challenging the prices charged for medical products and services.

          Medicare reimburses hospitals on a prospectively determined fixed amount for the costs associated with an in-patient hospitalization based on the patient’s discharge diagnosis, and reimburses physicians on a prospectively determined fixed amount based on the procedure performed, regardless of the actual costs incurred by the hospital or physician in furnishing the care and unrelated to the specific devices used in that procedure. Medicare and other third party payors are increasingly scrutinizing whether to cover new products and the level of reimbursement for covered products. In addition, Medicare traditionally has considered items or services involving devices that have not been approved or cleared for marketing by the FDA to be precluded from Medicare coverage. In July 1999, Centers for Medicare and Medicaid Services began coverage of FDA approved TMR systems for any manufacturer’s TMR procedures. In October of 1999, CMS further clarified its coverage policy to include coverage of TMR when performed as an adjunctive to CABG.

          In contrast to Medicare which covers a significant portion of the patients who are candidates for TMR, private insurers and health plans each make any individual decision whether or not to provide reimbursement for TMR and, if so, at what reimbursement level. We have limited experience to date ascertaining the acceptability of our TMR procedures for reimbursement by private insurance and private health plans. Private insurance and private health plans may not approve reimbursement for TMR or PMR. The lack of private insurance and health plans reimbursement may harm our business. Based on physician feedback, we believe many private insurers are reimbursing hospitals and physicians when the procedure is performed on non-Medicare patients. In May 2001, Blue Cross/Blue Shield’s Technology Evaluation Center (“TEC”) assessed our therapy and confirmed that both TMR and TMR used as an adjunct to bypass surgery, “improves net health outcomes.” While TEC decisions are not binding, many Blue Cross/Blue Shield plans and other third-party payers use the center as a benchmark and adopt into policy those therapies that meet the TEC assessment.

          In foreign markets, reimbursement is obtained from a variety of sources, including governmental authorities, private health insurance plans and labor unions. In most foreign countries, there are also private insurance systems that may offer payments for alternative therapies. Although not as prevalent as in the U.S., health maintenance organizations are emerging in certain European countries. We may need to seek international reimbursement approvals, and we may not be able to attain these approvals in a timely manner, if at all. Failure to receive foreign reimbursement approvals could make market acceptance of our products in the foreign markets in which such approvals are sought more difficult.

          We believe that reimbursement in the future will be subject to increased restrictions such as those described above, both in the U.S. and in foreign markets. We also believe that the escalating cost of medical products and services has led to and will continue to lead to increased pressures on the healthcare industry, both foreign and domestic, to reduce the cost of products and services, including products offered by us. Third party reimbursement and coverage may not be available or adequate in U.S. or foreign markets, current levels of reimbursement may be decreased in the future and future legislation, regulation, or reimbursement policies of third party payors may reduce the demand for our products or our ability to sell our products on a profitable basis. Fundamental reforms in the healthcare industry in the U.S. and Europe that could affect the availability of third party reimbursement continue to be proposed, and we cannot predict the timing or effect of any such proposal. If third party payor coverage or reimbursement is unavailable or inadequate, our business may suffer.

Product Liability and Insurance

          We maintain insurance against product liability claims in the amount of $10 million per occurrence and $10 million in the aggregate. We may not be able to obtain additional coverage or continue coverage in the amount desired or on terms acceptable to us, and such coverage may not be adequate for liabilities actually incurred. Any uninsured or underinsured claim brought against us or any claim or product recall that results in a significant cost to or adverse publicity against us could harm our business.

Employees

          As of December 31, 2003 we had 31 employees, of which 18 employees were in sales and marketing. None of our employees is covered by a collective bargaining agreement and we have not experienced any work stoppages to date.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

           This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains descriptions of our expectations regarding future trends affecting our business. These forward-looking statements and other forward-looking statements made elsewhere in this document are made in reliance upon the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Please read the section below titled “Factors Affecting Future Results” to review conditions which we believe could cause actual results to differ materially from those contemplated by the forward-looking statements. Forward-looking statements are identified by words such as “believes,” “anticipates,” “expects,” “intends,” “plans,” “will,” “may” and similar expressions. In addition, any statements that refer to our plans, expectations, strategies or other characterizations of future events or circumstances are forward-looking statements. Our business may have changed since the date hereof and we undertake no obligation to update these forward looking statements.

           The following discussion should be read in conjunction with financial statements and notes thereto included in this prospectus.

Overview

          CardioGenesis Corporation, formerly known as Eclipse Surgical Technologies, Inc., incorporated in California in 1989, designs, develops, manufactures and distributes laser-based surgical products and disposable fiber-optic accessories for the treatment of advanced cardiovascular disease through transmyocardial revascularization (“TMR”) and percutaneous transluminal myocardial revascularization (“PMR”).

           On February 11, 1999, we received final approval from the FDA for our TMR products for certain indications, and we are permitted to sell those products in the U.S. on a commercial basis. We have also received the European Conforming Mark (“CE Mark”) allowing the commercial sale of our TMR laser systems and our PMR catheter system to customers in the European Community. Effective July 1, 1999, Centers for Medicare and Medicaid Services (“CMS”) began providing Medicare coverage for TMR. As a result, hospitals and physicians are now eligible to receive Medicare reimbursement for TMR equipment and procedures performed on Medicare recipients.

           We have completed pivotal clinical trials involving PMR and study results were submitted to the FDA in a PMA application in December 1999 along with subsequent amendments. The PMR study compares PMR to conventional medical therapy in patients with no option for other treatment. In July 2001, the FDA Advisory Panel recommended against approval of PMR for public sale and use in the United States. In July 2003, the FDA agreed to an alternative process in which additional data in support of our PMA supplement for PMR could be submitted and reviewed by the FDA in an interactive review process. The data was submitted in August 2003 and the independent panel review by the MDDRP was cancelled. The FDA agreed to reschedule the MDDRP hearing in the future if the dispute cannot be resolved. The FDA has informed us that they believe the data submitted in August 2003 in connection with the interactive review process is still not adequate to support approval by the FDA of our PMR system. As part of the interactive review process, we met with the FDA in March 2004. At that time, the FDA was unable to reach a favorable outcome on our application for approval of PMR. We expect to meet with the FDA in the near future in order to clarify any needs for additional clinical data on PMR. At this time, we have determined not to proceed to a Medical Services Resolution Panel review of our PMR application, although that option remains available. There can be no assurance, however, that we will receive a favorable determination from the FDA in the future.

          As of December 31, 2003, we had an accumulated deficit of $164,958,000. We may continue to incur operating losses. The timing and amounts of our expenditures will depend upon a number of factors, including the efforts required to develop our sales and marketing organization, the timing of market acceptance of our products and the status and timing of regulatory approvals.

Results of Operations

Year Ended December 31, 2003 Compared to Year Ended December 31, 2002

     Net Revenues

          We generate our revenues primarily through the sale of our TMR laser base units and related handpieces, and related services . Net revenues of $13,518,000 for the year ended December 31, 2003 increased $470,000, or 4%, when compared to net revenues of $13,048,000 for the year ended December 31, 2002. The increase in net revenues was due to an increase in domestic handpiece and laser revenues of $268,000 and $286,000, respectively, offset by a decrease in international handpiece and laser sales of $9,000 and $69,000, respectively.

          The increase in handpiece revenue is primarily related to a higher average per unit selling price in 2003 as compared to 2002. In an effort to accelerate market adoption of the TMR procedure, we developed a program pursuant to which we loan lasers to hospitals in return for the hospital purchasing a minimum number of handpieces at a premium over the list price. In the year ended December 31, 2003, domestic handpiece revenue consisted of $2,649,000 in sales to customers operating under our loaned laser program, of which $781,000 was attributed to premiums associated with such sales. In the year ended December 31, 2002, domestic handpiece revenue consisted of $2,832,000 in sales of product to customers operating under our loaned laser program, of which $756,000 was attributed to premiums associated with such sales. In the years ended December 31, 2003 and 2002, sales of product to customers not operating under our loaned laser program were $6,387,000 and $5,937,000, respectively.

          For the year ended December 31, 2003, domestic laser sales increased by $286,000 compared to the year ended December 31, 2002 primarily from a moderate increase in the conversion of loaned lasers to outright sales. International sales, accounting for approximately 3% of total sales for the year ended December 31, 2003, decreased $78,000 from the prior year when international sales accounted for 4% of total sales. The decrease in international sales occurred primarily as a result of fewer handpiece sales resulting from decreased sales and marketing efforts in the international market compared to 2002. Service and other revenue of $971,000 slightly decreased by $6,000 for the year ended December 31, 2003 when compared to $977,000 for the year ended December 31, 2002.

     Gross Profit

          Gross profit increased to 83% of net revenues for the year ended December 31, 2003 as compared to 78% of net revenues for the year ended December 31, 2002. Gross profit in absolute dollars increased by $1,110,000 to $11,223,000 for the year ended December 31, 2003, as compared to $10,113,000 for the year ended December 31, 2002. The increase in gross profit as a percent of sales, and in absolute terms, resulted from improved margins on lasers sold. These margins improved primarily due to sales of lasers originally placed under our laser loan program that were converted to outright sales. In addition, margins on disposable handpieces increased due to improvements in manufacturing which resulted in higher yields.

     Research and Development

          Research and development expenditures of $1,944,000 increased $1,287,000 or 196% for the year ended December 31, 2003 when compared to $657,000 for the year ended December 31, 2002. The increase in overall research and development expense resulted primarily from an increase in costs for outside services of $463,000 related to the PMR approval process. For the year ended December 31, 2003, a reduction of $601,000 of accrued liabilities was recorded for estimated clinical trial obligations. This reduction of accrued liabilities decreased $828,000 from the corresponding reduction in the prior year.

     Sales, General and Administrative

          Sales, general and administrative expenditures of $9,590000 decreased $2,707,000 or 22% for the year ended December 31, 2003 when compared to $12,297,000 for the year ended December 31, 2002. The decrease in expenses resulted primarily from a decrease in employee expenses of $1,077,000 primarily related to reductions in our workforce. Additionally, outside services, advertising and marketing, training and clinical research, and facilities and office expense decreased $564,000, $396,000, $152,000, $118,000, respectively, due to overall cost cutting efforts.

25

     Interest and Other Income (Expense), Net

          Interest and other income (expense), net is comprised of interest income, interest expense and our former ownership interest in Microheart, Inc., a privately-held company (“Microheart”).

          Interest income of $7,000 decreased $32,000 or 82% for the year ended December 31, 2003 when compared to $39,000 for the year ended December 31, 2002. This decrease was due to lower interest rates and lower investments in cash equivalents.

          Interest expense of $44,000 increased $31,000 or 238% for the year ended December 31, 2003 when compared to $13,000 for the year ended December 31, 2002. This increase is primarily due to a higher level of financing for equipment under capital lease and amortization of debt issue costs.

          A gain on the sale of an investee of $2,285,000 for the year ended December 31, 2002 resulted from the sale of our ownership interest in Microheart in April 2002.

Year Ended December 31, 2002 Compared to Year Ended December 31, 2001

     Net Revenues

          Net revenues of $13,048,000 for the year ended December 31, 2002 decreased $1,105,000, or 8%, when compared to net revenues of $14,153,000 for the year ended December 31, 2001. The decrease in net revenues was due to a reduction in domestic handpiece revenues of $1,810,000 and international sales of $547,000 offset by an increase in domestic laser sales of $761,000 and in service and other revenue of $491,000.

          The decrease in handpiece revenue was primarily related to our then current strategy of concentrating our sales resources on increasing procedure volume in our existing installed base, which had the effect of reducing handpiece revenues from loaned laser placements, when compared to the levels attained in the year ended December 31, 2001. The decline in loaned laser placements in 2002, when compared to the prior year, resulted in a year-over-year reduction in the number of handpieces sold as each shipped laser is normally accompanied by an order for handpieces. In the year ended December 31, 2002, domestic handpiece revenue consisted of $2,832,000 in sales to customers operating under our loaned laser program, of which $756,000 was attributed to premiums associated with such sales. In the year ended December 31, 2001, domestic handpiece revenue consisted of $4,677,000 in sales of product to customers operating under our loaned laser program, of which $1,424,000 was attributed to premiums associated with such sales. In the years ended December 31, 2002 and 2001, sales of product to customers not operating under our loaned laser program was $5,937,000 and $5,902,000, respectively.

          For the year ended December 31, 2002, domestic laser sales increased by $761,000 compared to the year ended December 31, 2001 primarily from an increase in sales of lasers that were previously on loan in our installed base. International sales, accounting for approximately 4% of total sales for the year ended December 31, 2002, decreased $547,000 from the prior year when international sales accounted for 7% of total sales. This reduction in international sales occurred primarily as a result of fewer handpiece sales due to decreased shipments to distributors in the international market compared to 2001. Service and other revenue of $976,000 increased $491,000 for the year ended December 31, 2002 when compared to $485,000 for the year ended December 31, 2001 due primarily to an increase in the number of service contracts sold.

     Gross Profit

          Gross profit increased to 78% of net revenues for the year ended December 31, 2002 as compared to 59% of net revenues for the year ended December 31, 2001. Gross profit in absolute dollars increased by $1,737,000 to $10,113,000 for the year ended December 31, 2002, as compared to $8,376,000 for the year ended December 31, 2001. The increase in gross profit as a percent of sales, and in absolute terms, resulted from improved margins on lasers sold as well as improved margins on disposable handpieces. We achieved these improved margins through due to the outsourcing of disposables manufacturing which took place in the second half of 2001.

26

     Research and Development

          Research and development expenditures of $657,000 decreased $1,206,000 or 65% for the year ended December 31, 2002 when compared to $1,863,000 for the year ended December 31, 2001. While actual expenditures for research and development remained fairly constant from 2001 to 2002, the decrease in overall research and development expense resulted primarily from the effects of recording a total of $1.3 million in reductions of accrued liabilities recorded in prior years for estimated clinical trial obligations.

     Sales, General and Administrative

          Sales, general and administrative expenditures of $12,297,000 decreased $2,822,000 or 19% for the year ended December 31, 2002 when compared to $15,119,000 for the year ended December 31, 2001. The decrease in expenses resulted primarily from a decrease in employee expenses of $1,956,000. We achieved this decrease in expenses primarily related to reductions in our work force and overall cost cutting efforts. Additionally, facilities and office expenses decreased by $685,000 primarily as a result of the relocation of our corporate headquarters which was completed in the third quarter of 2001.

     Restructuring and Merger-Related Costs

          During the year ended December, 31 2001, we recognized restructuring charges of $1,303,000, which were partially offset by a change in estimate of $270,000 in connection with merger-related costs that were incurred in 1999. The 2001 restructuring charges related to the company-wide restructuring which began in the second quarter of 2001. The restructuring included a reduction in headcount, the closing of our facilities in Sunnyvale, California and the move to a new facility located in Foothill Ranch, California. As a result of the restructuring, 48 employees were identified to be terminated under the original restructuring plan, primarily from the finance and manufacturing departments.

          The following table summarizes the restructuring activity (in thousands):

     Interest and Other Income (Expense), Net

          Interest and other income (expense), net is comprised of interest income, interest expense and our ownership interest in Microheart.

          Interest income of $39,000 decreased $23,000 or 37% for the year ended December 31, 2002 when compared to $62,000 for the year ended December 31, 2001. This decrease was due to lower interest rates and lower investments in cash equivalents.

          Interest expense of $13,000 decreased $5,000 or 28% for the year ended December 31, 2002 when compared to $18,000 for the year ended December 31, 2001. This decrease reflected a lower level of debt outstanding.

27

          A gain on the sale of an investee of $2,285,000 for the year ended December 31, 2002 was related to the sale of our ownership interest in Microheart in April 2002. For the year ended December 31, 2001, the equity in net loss of $652,000 represented our share of the net loss of Microheart, in which our ownership was approximately 30% at the time the net loss was recorded.

Liquidity and Capital Resources

          Cash and cash equivalents were $1,013,000 at December 31, 2003 compared to $1,490,000 at December 31, 2002, a decrease of $477,000. We used $680,000 of cash for operating activities in the twelve months ended December 31, 2003 primarily to pay down accounts payable and accrued liabilities.

          Cash used in investing activities during the twelve months ended December 31, 2003 was $80,000. Cash provided by financing activities during the twelve months ended December 31, 2003 was $358,000 due to proceeds from employee stock option exercises and common stock purchased under the Employee Stock Purchase Plan.

          In March 2003, we entered into a Purchase and Security Agreement with a private equity fund and entered into a revolving Convertible Note credit facility (the “Note”) that matures on March 26, 2006. In conjunction with this transaction, we issued warrants to acquire 275,000 shares of our common stock. The warrants are exercisable for five years from the date of grant at exercise prices ranging from $.35 to $.44 per share. As of December 31, 2003, we had no outstanding borrowings on the Note. We intend to cancel the Note in the first quarter of 2004.

          On January 22, 2004, we sold 3,100,000 shares of common stock to private investors for a total price of $2,700,000. We also issued warrants to purchase 3,100,000 additional shares of common stock at a price of $1.37 per share. The warrants are immediately exercisable and have a term of five years. The investors also have an option to purchase approximately 1,570,000 shares of common stock at $1.00 per share for a period of six months following the effective date of a related registration statement to be filed in connection with the transaction. We agreed to file this registration statement covering the resale of shares within 50 days of the closing date of the transaction.

          We have incurred significant losses for the last several years and at December 31, 2003 we had an accumulated deficit of $164,958,000. Our ability to maintain current operations is dependent upon achieving and maintaining profitable operations or obtaining additional debt or equity financing.

          We also plan to continue our cost containment efforts by focusing on sales, general and administrative expenses. We have significantly reduced our cost of revenues, primarily due to the outsourcing of a significant portion of our manufacturing which allows us to purchase products at lower costs. To reduce operating expenses, we have focused our efforts on reducing headcount and overall expenses in functions that are not essential to core and critical activities.

          Currently, our primary goal is to maintain profitability. Our actions have been guided by this initiative, and the resulting cost containment measures have helped to conserve our cash. Our focus is upon core and critical activities, thus operating expenses that are nonessential to our core operations have been eliminated.

          We believe our cash balance as of December 31, 2003 and the proceeds from our January 2004 sale of common stock will be sufficient to meet our capital and operating requirements through the next 12 months. We believe that if revenues from sales or new funds from debt or equity instruments are insufficient to maintain the current expenditure rate, it will be necessary to significantly reduce our operations until an appropriate solution is implemented.

          We will have a continuing need for new infusions of cash if we incur losses in the future. We plan to increase our sales through increased direct sales and marketing efforts on existing products and achieving regulatory approval for other products. If our direct sales and marketing efforts are unsuccessful or we are unable to achieve regulatory approval for our products, we will be unable to significantly increase our revenues. We believe that if we are unable to generate sufficient funds from sales or from debt or equity issuances to maintain our current expenditure rate, it will be necessary to significantly reduce our operations. We may be required to seek additional

28

sources of financing, which could include short-term debt, long-term debt or equity. There is a risk that we may be unsuccessful in obtaining such financing and that we will not have sufficient cash to fund our operations.

           As part of the ongoing interactive review process for our PMR product we met with the FDA in March 2004. At that time, the FDA was unable to reach a favorable outcome on our application for approval of PMR. We expect to meet with the FDA in the near future in order to clarify any needs for additional clinical data on PMR. At this time, we have determined not to proceed to a Medical Services Resolution Panel review of our PMR application, although that option remains available. If we receive approval from the FDA to sell our PMR product in the United States, we intend to expend cash resources to educate potential customers and stimulate sales. We currently anticipate that our cash and cash equivalents and currently anticipated revenues combined with revenues from sales of our PMR products in the United States, if approved by the FDA, will be adequate to fund the introduction of our PMR product in the United States during 2004. However, if we experience unanticipated cash expenditures or revenues from the sale of our current products decrease, we may need to seek additional sources of funding, including debt or equity, in order to finance the introduction of PMR product in the United States. We cannot assure you, however, that we will receive a favorable determination from the FDA in the future.

Critical Accounting Policies and Estimates

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

          The following presents a summary of our critical accounting policies, defined as those policies we believe are: (i) the most important to the portrayal of our financial condition and results of operations, and (ii) that require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain.

     Revenue Recognition:

          We recognize revenue on product sales upon receipt of a purchase order, shipment of the products, the price is fixed or determinable and collection of sales proceeds is reasonably assured. Where purchase orders allow customers an acceptance period or other contingencies, revenue is recognized upon the earlier of acceptance or removal of the contingency.

          Revenues from sales to distributors and agents are recognized upon shipment when there is evidence that an arrangement exists, delivery has occurred under the Company’s standard FOB shipping point terms, the sales price is fixed or determinable and the ability to collect sales proceeds is reasonably assured. The contracts regarding these sales do not include any rights of return or price protection clauses.

          We frequently loan lasers to hospitals in return for the hospital purchasing a minimum number of handpieces at a premium over the list price. The loaned lasers are depreciated to cost of revenues over a useful life of 24 months. The revenue on the handpieces is recognized upon shipment at an amount equal to the list price. The

29

premium over the list price represents revenue related to the use of the laser unit and is recognized ratably, generally over the 24-month useful life of the placed lasers.

          Revenues from service contracts, rentals, and per procedure fees are recognized upon performance or over the terms of the contract as appropriate.

     Accounts Receivable:

          We regularly evaluate the collectability of accounts receivable based upon our knowledge of customers and compliance with credit terms. The allowance for doubtful accounts is adjusted based on such evaluation, with a corresponding provision included in general and administrative expenses.

     Inventories:

          Inventories are stated at the lower of cost (principally standard cost, which approximates actual cost on a first-in, first-out basis) or market value.

     Income Taxes:

          We account for income taxes using the liability method under which deferred tax assets or liabilities are calculated at the balance sheet date using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amounts expected to be realized.

Quantitative and Qualitative Disclosures About Market Risk

     Quantitative Disclosures

          We are exposed to market risks inherent in our operations, primarily related to interest rate risk and currency risk. These risks arise from transactions and operations entered into in the normal course of business. We do not use derivatives to alter the interest characteristics of our marketable securities or our debt instruments. We have no holdings of derivative or commodity instruments.

          Interest Rate Risk. We are subject to interest rate risks on cash and cash equivalents and any future financing requirements. Our long-term debt at December 31, 2003 consisted of an outstanding balance on a lease obligation.

          The following table presents the future principal cash flows or amounts and related weighted average interest rates expected by year for our existing cash and cash equivalents and long-term debt instruments:

30

     Qualitative Disclosures

          Interest Rate Risk. Our primary interest rate risk exposures relate to the impact of interest rate movements on our ability to obtain adequate financing to fund future operations.

          We manage interest rate risk on our outstanding long-term debts through the use of fixed rate debt. Our management evaluates our financial position on an ongoing basis.

          We do not hedge any balance sheet exposures and intercompany balances against future movements in foreign exchange rates. The exposure related to currency rate movements would not have a material impact on future net income or cash flows.

Consolidated Financial Statements and Supplementary Data

     Quarterly Results of Operations

          The following table sets forth certain quarterly financial information for the periods indicated. This information has been derived from unaudited financial statements that, in the opinion of management, have been prepared on the same basis as the audited information, and includes all normal recurring adjustments necessary for a fair presentation of such information. The results of operations for any quarter are not necessarily indicative of the results to be expected for any future periods.

          See the Index to Financial Statement on page F-1 for a listing of the consolidated financial statements and supplementary data filed as part of this prospectus.

Recently Issued Accounting Standards

          In May 2003, the Financial Accounting Standards Board (“FASB”) issued SFAS 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity.” SFAS 150 establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances). Many of those instruments were previously classified as equity. This Statement is effective for financial instruments entered into or modified after May 31, 2003 (except for mandatorily redeemable noncontrolling interests). For all instruments that existed prior to May 31, 2003, the Standard is effective at the beginning of the first interim period beginning after June 15, 2003 (except for mandatorily redeemable noncontrolling interests). For mandatorily redeemable noncontrolling interests, the FASB has deferred the provisions of FAS 150 until further notice. The provisions of SFAS 150 adopted thus far did not have a material

effect on our financial statements and the adoption of the remaining provision of SFAS 150 is not expected to have a material effect on our financial statements.

          In December 2003, the FASB issued FASB Interpretation No. 46R, “Consolidation of Variable Interest Entities (FIN 46R). FIN 46R requires the application of either FIN 46 or FIN 46R by Public Entities to all Special Purpose Entities (SPE) created prior to February 1, 2003 as of December 31, 2003 for calendar year-end companies. FIN 46R is applicable to all non-SPEs created prior to February 1, 2003 at the end of the first interim or annual period ending after March 15, 2004. For all entities created subsequent to January 31, 2003, Public Entities were required to apply the provisions of FIN 46. The adoption of FIN 46 did not have a material impact to our consolidated financial position, results of operations or cash flows. The adoption of FIN 46R for SPEs did not have an impact on our consolidated financial position, results of operations or cash flows, and we do not believe the adoption of FIN 46R for non-SPEs will have a material impact to our consolidated financial position, results of operations or cash flows.

          In December 2003, the SEC issued Staff Accounting Bulletin (“SAB”) No. 104, Revenue Recognition. SAB 104 codifies, revises and rescinds certain sections of SAB No. 101 in order to make this interpretive guidance consistent with current authoritative accounting and auditing guidance and SEC rules and regulations. Accordingly, there is no impact to our results of operations, financial position or cash flows as a result of the issuance of SAB No. 104.

Should a vacancy in the Board of Directors occur, the Nominating Committee will seek and nominate qualified individuals. The Nominating Committee will consider nominees for director whose names are timely submitted by holders of our common stock in writing addressed to the Chairman of the Nominating Committee accompanied by such information regarding the nominee as would be required under the rules of the Securities and Exchange Commission were the shareholder soliciting proxies with regard to the election of such nominee.

          Compensation Committee. Our Compensation Committee currently consists of Robert L. Mortensen, Robert C. Strauss and Joseph R. Kletzel, II. The Compensation Committee met one time in 2003. This committee reviews and approves our executive compensation policy and plan.

Compensation Committee Interlocks and Insider Participation

          No member of the Compensation Committee has a relationship that would constitute an interlocking relationship with executive officers or directors of another entity.

Director Compensation

          For serving on the Board of Directors, directors who are not compensated as our employees or as consultants to us receive fees of $1,500 per board meeting and $500 per committee meeting, provided such committee meeting does not occur on the same day as a board meeting. We also have a Director Stock Option Plan for non-employee directors. In 2003, directors Joseph R. Kletzel, II, Robert C. Strauss and Robert L. Mortensen were each granted an option to purchase an aggregate of 7,500 shares of common stock upon re-election to our Board of Directors in May 2003.

Employment Agreements

          Michael J. Quinn entered into an employment agreement with us on September 27, 2001 which was amended on July 3, 2002. Mr. Quinn’s employment agreement provides for an annual salary of $369,930, subject to annual review and increase at the discretion of the Board of Directors. Mr. Quinn may also be entitled to receive (i) an annual bonus, the amount of which shall be determined by the Board of Directors, not to exceed 50% of Mr. Quinn’s annual salary, and (ii) options or other rights to acquire our common stock, under terms and conditions determined by the Compensation Committee of the Board of Directors. Mr. Quinn’s employment agreement provides that his employment is for an initial term of three years, which automatically renews for one year terms after the initial term unless terminated in writing thirty days prior to the commencement of a new one year term. Mr. Quinn may be terminated at any time with or without cause subject to certain termination provisions.

          In November 2003, our employment relationship with Darrell Eckstein was terminated. In connection with his departure, Mr. Eckstein has made certain breach of contract claims arising out his employment agreement with us, as well as certain tort claims. Pursuant to the terms of Mr. Eckstein’s employment agreement, we have agreed to submit the matter to binding arbitration. We believe Mr. Eckstein’s claims are without merit and we intend to vigorously defend against these claims.

          The following table sets forth information regarding grants of stock options to purchase shares of our common stock made to the executive officers who appear in the Summary Compensation Table above during the year ended December 31, 2003.

Aggregate Option Exercises in Last Fiscal Year and Fiscal Year-End Option Values

          The following table sets forth certain information for the year ended December 31, 2003 concerning exercised, exercisable and unexercisable stock options held by each of the executive officers in the Summary Compensation Table above.

Stock Option and Other Benefit Plans

          Our Stock Option Plan, as restated in June 2003, was adopted by the Board of Directors and approved by the shareholders in April 1996. The total number of shares currently reserved for issuance under the Option Plan is 8,600,000 shares. The Option Plan terminates in March 2006. We believe the Option Plan is an essential tool to link the long-term interests of shareholders and employees, especially executive management, and serves to motivate executives to make decisions that will, in the long term, give the best returns to shareholders. Stock options are generally granted when an employee joins us, with subsequent grants also taking into account the individual’s performance and the vesting status of previously granted options. These options typically vest over a three year period and are granted at an exercise price equal to the fair market value of our common stock at the date of grant. The sizes of initial option grants are based upon the position, responsibilities and expected contribution of the individual. This approach is designed to maximize shareholder value over a long term, as no benefit is realized from the option grant unless the price of our Common Stock has increased over a number of years.

          In addition to the Option Plan, our employees are eligible to participate in our 1996 Employee Stock Purchase Plan, as restated in June 2003 (the “ESPP”). The total number of shares currently reserved for issuance under the ESPP is 850,000 shares. The ESPP terminates in April 2006. The ESPP allows employees to purchase shares of our common stock at a price equal to 85% of the lower of the fair market value at the beginning of the offering period or the fair market value at the end of the purchase period.

          We also maintain a Directors’ Stock Option Plan which provides for the grant of nonstatutory options to directors who are neither officers nor employees of ours. We currently have 575,000 shares of common stock reserved for issuance under this plan. Under this plan, options are granted at the trading price of the common stock at the date of grant. Options generally vest over twelve to thirty-six months and expire ten years from date of grant. No shares of common stock issued under this plan are subject to repurchase.

          Other elements of employee benefits include life and long-term disability insurance, medical benefits and a 401(k) plan with an employer matching contribution for the fiscal year ended December 31, 2003. All such benefits are available to all of our regular, full-time employees. We also maintain a Management Incentive Compensation Program for officers and certain other management positions, pursuant to which bonuses are paid out if we attain certain bonus targets.

Limitation of Directors and Officers Liability

          As allowed by the California Corporations Code, we have adopted provisions in our articles of incorporation that provide that the liability of our directors for monetary damages shall be eliminated to the fullest extent permissible under California law. Furthermore, our articles of incorporation provide that we are authorized to provide indemnification of agents (including directors and executive officers) through bylaw provisions or through agreements with the agents, or both, in excess of the indemnification otherwise permitted by Section 317 of the California Corporations Code, subject only to the applicable limits set forth in Section 204 of the California Corporations Code with respect to actions for breach of duty to the company and its shareholders. Our amended and restated bylaws provide that our agents shall be indemnified against expenses actually and reasonably incurred by them in connection with the successful defense on the merits in any proceeding that they are a party to by reason of the fact that they were agents of ours, but only if they acted in good faith, in a manner that they believed to be in our best interests (or in certain instances, in a manner that they did not believe to be contrary to our best interests), and with such care as a reasonably prudent person in a like position would use under similar circumstances.

          If an agent is not successful on the merits in any such proceeding, then we will only indemnify the agent if it is determined that the agent has satisfied the foregoing standard of conduct, and such determination is made by:

          However, our amended and restated bylaws provide that, in the case of an action by or in the right of us, no indemnification will be permitted:

          Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors or officers pursuant to the foregoing provisions, or otherwise, in the opinion of the Securities and Exchange Commission, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

          We enter into indemnification agreements with our officers and directors. We maintain insurance policies which insure our directors and officers against certain liabilities.

          At present, there is no pending litigation or proceeding involving any of our directors, officers, employees or other agents as to which indemnification is being sought, nor are we aware of any pending or threatened litigation that may result in claims for indemnification by any director, officer, employee or other agent.
