Part I

Item 1. Business

(a)General Development of Business

Overview

We are a provider of innovative medical devices used in minimally invasive, image-guided procedures to treat peripheral vascular disease, or PVD, and local oncology therapy options for treating cancer, including radiofrequency ablation, or RFA, systems, irreversible electroporation, or IRE, surgical resection systems and embolization products for treating benign and malignant tumors. We design, develop, manufacture and market a broad line of therapeutic and diagnostic devices that enable interventional physicians (interventional radiologists, vascular surgeons, surgical oncologists and others) to treat PVD, tumors, and other non-coronary diseases. Unlike several of our competitors that focus on the treatment of coronary diseases, we believe that we are the only company whose primary focus is to offer a comprehensive product line for the interventional treatment of PVD, tumors and other non-coronary diseases.

We have been in business since 1988. Our corporate headquarters is located at 603 Queensbury Avenue, Queensbury, New York 12804. Our phone number is (518) 798-1215.

History

AngioDynamics was founded in 1988 as a division and incorporated in 1992 in Delaware as a wholly owned subsidiary of E-Z-EM. We completed our initial public offering in 2004 by raising net proceeds of approximately $21.7 million at an offering price of $11.00 per share. In 2006 we completed a follow-on offering, raising net proceeds of approximately $61.9 million at a public offering price of $24.07 per share.

Recent Developments

CEO Transition

On January 20, 2009, we entered into an Employment Agreement and Non-Statutory Stock Option Agreement with our then chief executive officer that provided, among other things, for a transition to a new chief executive officer. The transition to the new chief executive was completed in the third quarter of fiscal 2009. The former chief executive officer did not have an operating role after February 28, 2009. Accordingly, we recorded a provision in fiscal 2009 of approximately $2.9 million in general and administrative expenses for all current and future costs associated with the aforementioned Employment Agreement and Non-Statutory Stock Option Agreement and certain costs associated with the recruitment of a new chief executive officer. The new CEO commenced employment with us in March 2009.

Acquisition of FlowMedica, Inc.

On January 12, 2009, we completed the acquisition of certain assets of FlowMedica, Inc. for approximately $1.75 million in cash and a contingent payment based on fiscal 2011 sales of FlowMedica products. With this acquisition, we purchased the Benephit product line, a therapeutic approach to deliver drugs directly to the kidneys in order to prevent and treat acute kidney injury, in the emerging field of Targeted Renal Therapy. Intangible assets acquired totaled approximately $1.3 million which have been identified as product technologies (10-year weighted average useful life). Inventory acquired totaled approximately $400,000. The acquisition is being accounted for as a purchase and, accordingly, we have included the results of operations in the financial statements effective January 12, 2009, the date of acquisition. The pro-forma effects of the acquisition were not material to our income statement and balance sheet. Ten employees of FlowMedica, Inc. became employees upon completion of the acquisition.

Acquisition of Certain Assets of Diomed

On June 17, 2008, we completed the acquisition of certain U.S. assets of Diomed, Inc. and UK assets of Diomed UK Limited., in separate transactions, for an aggregate purchase price of approximately $11.1 million in cash including capitalized acquisition costs. With this acquisition, we substantially strengthened our position in the market for the treatment of varicose veins. The combination of Diomed endovenous laser products with our existing venous product line provides us with a comprehensive venous product offering. The total of the net tangible assets acquired was $5.5 million. Goodwill recorded as a result of these acquisitions was approximately $1.9 million. Intangible assets acquired, other than goodwill, totaled approximately $3.7 million of which $3.6 million has been identified as customer relationships (8 -year estimated weighted average useful life) and $100,000 has been identified as product technologies (10 -year estimated weighted average useful life).

The acquisition is being accounted for as a purchase and, accordingly, we have included the results of operations in the financial statements effective June 17, 2008, the date of acquisition. The pro-forma effects of the Diomed acquisition on our income statement and balance sheet were not material. Thirty five employees of Diomed became employees of ours upon completion of the acquisition.

Acquisition of Oncobionic

On May 9, 2008, we completed the acquisition of all the issued and outstanding shares of capital stock of Oncobionic, Inc. pursuant to the terms of the Stock Purchase Agreement entered into on October 12, 2006. The closing of the acquisition came as a result of the successful use of irreversible electroporation (IRE) technology in the first human clinical trial for the treatment of soft tissue, conducted during the first week of April 2008.

Under the October 2006 Stock Purchase Agreement, we agreed to pay a total purchase price of $25.4 million, including $400,000 of assumed liabilities. We made payments of $5.0 million upon the execution of the stock purchase agreement in October 2006, $10.0 million on May 9, 2008 upon the closing of the acquisition, and $5.0 million in November 2008. The remaining $5.0 million is payable in November 2009.

The Stock Purchase Agreement also provides for future royalty payments due on net sales of any catheter-based products sold by us that incorporate irreversible electroporation technology (“IRE”). We hold a license to such technology under a license agreement with the Regents of the University of California (the “UC License”).

We have accounted for the acquisition of Oncobionic as a purchase under accounting principles generally accepted in the United States of America. Under the purchase method of accounting, the assets and liabilities of Oncobionic were recorded as of the acquisition date, at their respective fair values, and consolidated with those of AngioDynamics. $25.2 million of the purchase price was recorded as product technology and is being amortized over a 15 year useful life. We recorded goodwill and a deferred tax liability of $9.3 million. In future periods the deferred tax liability will be reduced to offset the tax impact of non-deductible amortization expense

4

on the intangible assets acquired. The pro-forma impact on prior year results of operations would be approximately $1,680,000 of additional amortization expense or $1,040,000, net of tax.

(b)Narrative Description of Business

General

Historically, we reported our results of operations as a single segment. Beginning June 1, 2008, we organized our business into three reportable segments: Peripheral Vascular, Access and Oncology/Surgery. The Peripheral Vascular segment is comprised of the venous, angiographic, PTA, drainage and thrombolytic product lines. The Access segment is comprised of the dialysis, ports and PICC product lines. The Oncology/Surgery segment is comprised of the RFA, embolization, Habib and NanoKnife product lines. Prior periods have been recast for net sales and gross profit for this new reporting structure.

Our principal competitive advantages are our dedicated market focus, established brands and innovative products. We believe our dedicated focus enhances patient care and engenders loyalty among our customers. As a provider of interventional devices for over two decades, we believe we have established AngioDynamics’ brands as premium performance products. We collaborate frequently with leading interventional physicians in developing our products and rely on these relationships to further support our brands.

In January 2007, we completed the acquisition of RITA Medical Systems, Inc., (“RITA”), which clarified our position, we believe, as the only company focused on minimally-invasive treatments for cancer patients with an emphasis on the growing segment of interventional oncology. This acquisition created a diversified medical technology company with a broad line of access, diagnostic and therapeutic products that enable interventional physicians and surgeons to treat peripheral vascular disease and cancerous tumors. Interventional oncology is a large and growing area for our existing customer base and RITA’s leadership position, premium products and excellent reputation fit our strategy. RITA had a very strong position in vascular access ports, which are an ideal sales fit with our Morpheus^® CT PICC. In addition, in May 2008 we acquired irreversible electroporation (IRE) technology which will be complementary to RITA’s diverse offering of local oncology therapies, including its market-leading RFA systems, Habib Sealer^TM resection devices and LC Beads^TM for tumor embolization. We are in the process of commercializing the IRE technology. In June 2008, we completed the acquisition of certain U.S. and U.K. assets of Diomed, Inc. With this acquisition, we substantially strengthened our position in the market for the treatment of varicose veins. The combination of Diomed endovenous laser products with our existing venous product line provides us with a comprehensive venous product offering. In January 2009, we completed the acquisition of certain assets of FlowMedica, Inc. providing us with the Benephit product line, a therapeutic approach to deliver drugs directly to the kidneys in order to prevent and treat acute kidney injury, in the emerging field of Targeted Renal Therapy.

We sell our broad line of quality devices in the United States through a direct sales force and outside the U.S. through a combination of direct sales and distributor relationships. At May 31, 2009, our sales organization numbered 139 in the U.S. and 15 outside the U.S. including direct sales representatives, clinical specialists, and management personnel. For fiscal years 2009, 2008 and 2007, net sales outside the U.S. as a percentage of total net sales were 11.1%, 9.5%, and 6.3% respectively. Sales to any one country outside the U.S. did not comprise a material portion of our net sales in any of the last three fiscal years. We support our customers and sales organization with a marketing staff that includes product managers, customer service representatives and other marketing specialists. Our dedicated sales force, growing portfolio of products and acquisitions have contributed to our strong sales growth.

Peripheral Vascular Disease

Peripheral vascular disease encompasses several conditions in which the arteries or veins that carry blood to or from the legs, arms or non-cardiac organs become narrowed, obstructed or stretched. Structural deterioration in the blood vessels due to aging and the accumulation of atherosclerotic plaque results in restricted or

5

diminished blood flow. Common symptoms include numbness, tingling, persistent pain or cramps in the extremities, and deterioration of organ function, such as renal failure or intestinal malabsorption. Common PVDs also include venous insufficiency, a malfunction of one or more valves in the leg veins, which often leads to painful varicose veins and/or potentially life-threatening blood clots, and abdominal aortic aneurysms, or AAA, a ballooning, or stretching, of the aorta, which can lead to a potentially fatal rupture. Individuals who are older than age 50, smoke, are overweight, have lipid (i.e., cholesterol) disorders, are diabetic or have high blood pressure are at the greatest risk of developing PVD.

Peripheral Interventional Medicine

Peripheral interventional medicine involves the use of minimally invasive, image-guided procedures to treat peripheral vascular and other non-coronary diseases. In these procedures, x-rays, ultrasound, MRI and other diagnostic imaging equipment are used to guide tiny instruments, such as catheters, through blood vessels or the skin to treat diseases. Increasing use of these techniques has accompanied advances in device designs and imaging technologies that enable physicians to diagnose and treat peripheral disorders in a much less invasive manner than traditional open surgery. Interventional procedures are generally less traumatic and less expensive, as they involve less anesthesia, a smaller incision and a shorter recovery time.

Peripheral interventional procedures are performed primarily by physicians specially trained in minimally-invasive, image-guided techniques. This group of interventional physicians includes interventional radiologists, vascular surgeons and others. Interventional radiologists are board-certified radiologists who are fellowship trained in image-guided, percutaneous (through the skin) interventions. These physicians historically have developed many interventional procedures, including balloon angioplasty, vascular stenting and embolization, and perform the majority of peripheral interventional procedures. There are currently more than 5,000 interventional radiologists in the United States performing more than four million procedures annually. Vascular surgeons have traditionally been trained for open surgical repair of arterial and venous disorders. A large number are now increasingly performing interventional procedures and accredited vascular surgery training programs now generally require instruction in interventional, image-guided peripheral vascular procedures. Increasingly, interventional radiologists and vascular surgeons are forming joint practices to capture additional patient referrals by providing a broader range of interventional treatments. Other physicians who perform peripheral interventional procedures include interventional cardiologists and interventional nephrologists.

Interventional and Surgical Oncology

Interventional oncology is an emerging specialty in which minimally-invasive techniques and technologies are used to diagnose and treat cancers throughout the body. Percutaneous biopsy, chemoembolization, tumor ablation, PICC and port implantation, and radiofrequency ablation are just a few of the numerous procedures performed by interventional oncologists. In collaboration with other medical specialties focused on the cancer patient, the interventional oncologist brings an expertise in advanced imaging, catheter-based techniques, and minimally-invasive procedures not found in other medical specialties.

Products

Our current product offerings fall under three product groupings, which are paralleled by our organizational structure of three Strategic Business Units – Peripheral Vascular, Access and Oncology/Surgery.

All products discussed below have been cleared for sale in the United States by the U.S. Food and Drug Administration (FDA).

We have registered a number of marks with the U.S. Patent and Trademark Office, including Pulse*Spray; MORPHEUS CT; EVENMORE; ABSCESSION; TOTAL ABSCESSION; SPEEDLYSER; ANGIOFLOW; HYDROTIP; MEMORY TIP; SOS OMNI; StarBurst LifeJet; Circle C; Vortex; LifeGuard; NeoStar; LifeValve;

6

Centros; DuraMax; SmartPort; Profiler; VenaCure EVLT; NanoKnife; Benephit; and SOFT-VU. This annual report on Form 10-K also contains trademarks of companies other than AngioDynamics.

PERIPHERAL VASCULAR

The Peripheral Vascular Strategic Business Unit manages our Venous, Angiographic, PTA, Drainage, Thrombolytic Targeted Renal Therapy, Micro Access and Transjugular Access product lines.

Venous Products

Our venous products consist of our VenaCure EVLT™ products and Sotradecol^®.

Our VenaCure EVLT products are used in endovascular laser procedures to treat superficial venous disease (varicose veins). Superficial venous disease is a malfunction of one or more valves in the leg veins. These procedures are a less invasive alternative to vein stripping for the treatment of this condition. Vein stripping is a lengthy, painful and traumatic surgical procedure that involves significant patient recovery time. In contrast, venous laser treatment is an outpatient procedure that generally allows the patient to quickly return to normal activities with no scarring and minimal post-operative pain.

With our VenaCure EVLT products, laser energy is used to stop the source of the pressure by ablating, or collapsing and destroying, the affected vein. The body subsequently routes the blood to other healthy veins. Our products are sold as a system that includes a diode laser with our family of disposable laser fiber components, training and marketing materials. The diode laser is a self-contained reusable instrument. The disposable components in the system include a laser fiber system, an access sheath, access wires and needles. The training and marketing materials include a two-day physician training course, a comprehensive business development package and patient marketing materials.

An important part of our focus on the peripheral vascular disease market is the treatment of varicose veins. With an estimated one-half of all Americans older than age 60 suffering from varicose veins, the market for this treatment is large and growing. We believe that Sotradecol^® , a sclerosing drug approved by the FDA that we introduced in November 2005, combined with our currently available precision drug-delivery catheter technology, such as UNI*FUSE™, will become an important method of treating varicose veins. Sotradecol has been shown to be an effective treatment of small, uncomplicated varicose veins of the lower extremities, in addition to ablation of the great saphenous vein. Catheter-directed sclerotherapy has the advantages of requiring no investment in capital equipment and requires no local anesthesia because it is virtually pain free.

We believe that laser-based treatment systems will continue to be an important part of the vein treatment market in the United States for some time, but that laser treatments may eventually be eclipsed by catheter-directed sclerotherapy, as has occurred in Europe. This approach to treating varicose veins has the potential for greater intellectual property protection than our laser-based VenaCure products and, most importantly, can be incorporated with some of our existing patented products. Bioniche Pharma Group Limited has appointed us the exclusive distributor to all “persons” in the United States of Sotradecol, which may include hospital pharmacies, group purchasing organizations and wholesalers, as well as all physicians, for use in treating varicose veins or other approved vascular indications. Sotradecol is the only FDA-approved sodium tetradecyl sulfate injection currently available in the United States.

Angiographic Products and Accessories

Angiographic products and accessories are used during virtually every peripheral vascular interventional procedure. These products permit interventional physicians to reach targeted locations within the vascular system to deliver contrast media for visualization purposes and therapeutic agents and devices, such as stents or PTA balloons. Angiographic products consist primarily of angiographic catheters, but also include entry needles and guidewires specifically designed for peripheral interventions and fluid management products.

7

We manufacture angiographic catheters that are available in more than 500 tip configurations and lengths, either as standard items or made to order, and an advanced guidewire.

• SOFT-VU^®. Our proprietary SOFT-VU technology incorporates a soft, atraumatic tip that is easily visualized under fluoroscopy.

• ANGIOPTIC^TM. The ANGIOPTIC line is distinguished from other catheters because the entire instrument is highly visible under fluoroscopy.

• Accu-Vu^TM. The Accu-Vu is a highly visible, accurate sizing catheter used to determine the length and diameter of a vessel for endovascular procedures. Accu-Vu provides a soft, highly radiopaque tip with a choice of platinum radiopaque marker patterns along the shaft for enhanced visibility and accuracy. Sizing catheters are used primarily in preparation for aortic aneurysm stent-grafts, percutaneous balloon angioplasty, peripherally placed vascular stents and vena cava filters.

• Mariner^TM. The Mariner is a hydrophilic-coated angiographic catheter. It uses our patented Soft-Vu catheter technology to deliver contrast media to anatomy that is difficult to reach. The advanced hydrophilic coating technology significantly reduces catheter surface friction, providing smoother navigation through challenging vasculature with optimal handling and control.

• AQUALiner^®. The AQUALiner is a technologically advanced guidewire. This guidewire is used to provide access to difficult to reach locations in interventional procedures requiring a highly lubricious wire. The AQUALiner guidewire incorporates proprietary advanced coating technology that allows smooth frictionless navigation.

We offer uncoated, Teflon-coated and hydrophilic-coated guidewires to support our core angiographic catheter line.

PTA Products

PTA (percutaneous transluminal angioplasty) procedures are used to open blocked blood vessels and dialysis access sites using a catheter that has a balloon at its tip. When the balloon is inflated, the pressure flattens the blockage against the vessel wall to improve blood flow. PTA is now the most common method for opening a blocked vessel in the heart, legs, kidneys or arms.

Our PTA dilation balloon catheters include:

• WORKHORSE^®. The WORKHORSE product is a high-pressure, low-profile, non-compliant balloon catheter offered in 54 configurations. While the WorkHorse can perform other peripheral PTA procedures, we believe the device is used primarily for treating obstructed dialysis access sites.

• WORKHORSE^® II. The WORKHORSE II is a high-pressure, low-profile, non-compliant PTA balloon catheter. This product is an extension to our WORKHORSE PTA catheter, with enhanced WORKHORSE features to improve product performance during declotting procedures for dialysis access sites.

• PROFILER^®. The PROFILER is a low-profile, high-pressure, non-compliant, high-visibility balloon catheter that features a soft, radiopaque, tapered tip and a flexible, non-kinking catheter shaft with exceptional pushability. The low profile of the PROFILER opens access to small vessels and tortuous anatomy and is available with multiple balloon sizes and catheter lengths.

Drainage Products

Drainage products percutaneously drain abscesses and other fluid pockets. An abscess is a tender inflamed mass that typically must be drained by a physician.

8

Our line of drainage products consists of our TOTAL ABSCESSION^® general drainage catheters, which we introduced in December 2005, and ABSCESSION^® general and biliary drainage catheters. These products feature our proprietary soft catheter material, which is designed for patient comfort. These catheters also recover their shape even if bent or severely deformed when patients roll over and kink the catheters during sleep. Our TOTAL ABSCESSION general drainage catheter features a tamper-resistant locking mechanism known as the VAULT^®. This locking mechanism eliminates the need to replace drainage catheters that become unlocked during routine use, thus reducing physician time and increasing patient comfort. The TOTAL ABSCESSION catheter permits aspiration while locked or unlocked thus allowing more accurate placement and greater versatility for draining complex situations.

Thrombolytic Products

Thrombolytic catheters are used to deliver thrombolytic agents, which are drugs that dissolve blood clots in hemodialysis access grafts, arteries, veins and surgical bypass grafts. Our thrombolytic catheters include:

• PULSE*SPRAY^® and UNI*FUSE catheters. Our PULSE*SPRAY and UNI*FUSE catheters improve the delivery of thrombolytic agents by providing a controlled, forceful and uniform dispersion. Patented slits on the infusion catheter operate like tiny valves for an even distribution of thrombolytic agents. We believe that these slits reduce the amount of thrombolytic agents and the time necessary for these procedures, resulting in cost savings and improved patient safety.

• SPEEDLYSER^®. Our SPEEDLYSER thrombolytic catheter is used to deliver thrombolytic agents into obstructed dialysis grafts. This catheter features PULSE *SPRAY slit technology that simplifies catheter insertion and drug delivery.

Targeted Renal Therapy

With the acquisition of certain assets of FlowMedica on January 12, 2009, AngioDynamics purchased the Benephit product line – a therapeutic approach to deliver drugs directly to the kidneys in order to prevent and treat acute kidney injury. Benephit is representative of the emerging field of Targeted Renal Therapy, which is the delivery of therapeutic agents directly to the kidneys via the renal arteries as an alternative to the standard delivery method of systemic intravenous (IV) infusion to address kidney dysfunction related to a number of conditions, including cardiovascular, endovascular, surgical procedures and diseases. Systemic infusion often is associated with serious side effects such as hypotension. Clinicians have postulated that the amount of medication that reaches the kidneys via systemic infusion often does not attain therapeutic levels and therefore lead to treatment failure. As a result, physicians are now assessing the premise that Targeted Renal Therapy may maximize the benefit of medications because drugs can be delivered in therapeutic doses directly to the kidneys through the renal arteries. Targeted Renal Therapy can be used in numerous hospital settings including the Coronary Catheterization Laboratory, the Radiology Laboratory, the Surgical Suite, the Intensive Care Unit (ICU) and the Coronary Care Unit (CCU). Clinical use of FlowMedica’s Benephit^® CV Infusion System and Benephit XT Infusion System may prove beneficial to interventional cardiologists, interventional radiologists, nephrologists, and interventionally-skilled cardiothoracic and vascular surgeons.

Micro Access

Our micro access sets provide interventional physicians a smaller introducer system for minimally-invasive procedures. AngioDynamics’ Micro Access product line provides physicians with the means to build a custom set from the wide selection of configurations available, including four wires in two different lengths, seven needle options and three sheath dilator options.

9

Transjugular Access

Our transjugular liver access set is used to provide access in a transjugular intrahepatic portosystemic shunt (TIPS) procedure. A TIPS procedure involves placing a shunt in the liver between the hepatic and portal veins. This relieves the pressure on the portal system in an effort to resolve the bleeding complications often encountered in end-stage liver failure.

ACCESS

The Access Strategic Business Unit manages our Dialysis, Port and PICC product lines.

Dialysis Products

We market a complete line of dialysis products that provide short and long-term vascular access for dialysis patients. Dialysis, or cleaning of the blood, is necessary in conditions such as acute renal failure, chronic renal failure and end-stage renal disease, or ESRD. The kidneys remove excess water and chemical wastes from blood, permitting clean blood to return to the circulatory system. Waste substances cannot be excreted when the kidneys malfunction, creating an abnormal buildup of wastes in the bloodstream. Dialysis machines are used to treat this condition. Dialysis catheters, which connect the patient to the dialysis machine, are used at various stages in the treatment of every dialysis patient.

We currently offer a wide variety of dialysis catheters, including:

• DuraMax^TM. The DuraMax catheter is AngioDynamics’ latest evolution of our market-leading, stepped-tip catheter design. It incorporates numerous design enhancements that improve ease of use, dialysis efficiency and overall patient outcomes. DuraMax is the initial dialysis catheter that is fully manufactured by AngioDynamics.

• SCHON^TM. The SCHON chronic dialysis catheter is designed to be self-retaining, deliver high flow rates and provide patient comfort. The Schon is for long-term use.

• EVENMORE^®. The EVENMORE is a low-profile, end-hole design catheter that provides very efficient dialysis. It was designed for long-term use with our proprietary Durathane^® shaft, which offers high resistance to chemicals used to clean the insertion site.

• DURA-FLOW^TM. The DURA-FLOW chronic dialysis catheter is designed to be durable, maximize flow rates and provide for easier care and site maintenance. The Dura-Flow chronic dialysis catheter is for long-term use.

• SCHON XL^®. The SCHON XL acute dialysis catheter is designed to be kink resistant, deliver high flow rates, offer versatile positioning and provide patient comfort. SCHON XL is for short-term use.

• LIFEJET^® F-16. The LIFEJET F-16 chronic dialysis catheter features a unique “Circle C” lumen design and the largest internal diameter available. This facilitates high flow rates while keeping arterial and venous pressures low.

We purchase some products from Medical Components, Inc., or Medcomp, and resell under our name, including our Schon, Schon XL and Dura-Flow dialysis catheters under an exclusive worldwide license. We also purchase our Dynamic Flow catheters under a non-exclusive license from Medcomp.

Image-Guided Vascular Access

Image-guided vascular access, or IGVA, involves the use of advanced imaging equipment to guide the placement of catheters that deliver primarily short-term drug therapies, such as chemotherapeutic agents and antibiotics, into the central venous system. Delivery to the circulatory system allows drugs to mix with a large volume of blood as compared to intravenous drug delivery into a superficial vessel. IGVA procedures include the placement of peripherally inserted central catheter, or PICC, lines, implantable ports and central venous catheters, or CVCs.

10

Our PICC products include:

• MORPHEUS^® CT PICC. MORPHEUS^® CT PICC Insertion Kit. In May 2006, we introduced our insertion kit, which allows our Morpheus CT PICC to be inserted at a patient’s bedside instead of in the hospital radiology suite. The kit was specifically designed for interventional radiologists, nurse practitioners, physician assistants and radiology technicians who perform placement of PICC lines. These PICC lines provide short or long-term peripheral access to the central venous system for intravenous therapy and blood sampling. They are constructed of a biocompatible and durable material called Durathane^®, and have increased stiffness from the proximal end to the distal end, which provides ease of use and enhanced patient safety and comfort. These products are intended for use with CT injectors, allowing physicians to use the existing PICC for both medications and CT imaging, thus avoiding the need for an additional access site.

Ports are implantable devices utilized for the central venous administration of a variety of medical therapies and for blood sampling and diagnostic purposes. Central venous access facilitates a more systemic delivery of treatment agents, while mitigating certain harsh side effects of certain treatment protocols and eliminating the need for repeated access to peripheral veins. Depending upon needle gauge size and the port size, a port can be utilized for up to approximately 2,000 accesses once implanted in the body. Our ports are used primarily in systemic or regional short and long-term cancer treatment protocols that require frequent infusions of highly concentrated or toxic medications (such as chemotherapy agents, antibiotics or analgesics) and frequent blood samplings.

Our port products and accessories include:

• Our Vortex^® line of ports is a clear-flow port technology that, we believe, revolutionized port design. With its rounded chamber, the Vortex^® is designed to have no sludge-harboring corners or dead spaces. This contrasts to conventional ports where a squared reservoir design promotes sludge accumulation setting the stage for occlusions and infections. A tangential stem adds to the flow dynamics, which is designed to result in a hyper-cleaning flow process to remove blood deposits and drug residuals. This product line consists of the following titanium, plastic and dual-lumen offerings within its family of products: (i) Vortex VX; (ii) Vortex TR; (iii) Vortex LP; and (iv) Vortex MP.

• The Smart Port^™ power-injectable port with Vortex technology is a new type of port that offers the ability for a clinician to access a vein for both the delivery of medications or fluids and for administering power-injected contrast to perform a Computed Tomography (CT) scan. The ability to access a port for power-injected contrast studies eliminates the need for additional needle sticks in the patient’s arm and wrist veins. Once implanted, repeated access to the bloodstream can be accomplished with greater ease and less discomfort.

• The LifeGuard^™ Safety Infusion Set and The LifeGuard Vision^™ are used to infuse our ports and complement our port and vascular access catheters. The innovative design of these products was developed with the input of clinicians to provide safer needle placements, and the needles’ low profile design is intended to allow clinicians to easily dress the site. We believe that the ease of use and visual confirmation of safety is ideal in the clinical setting.

Our central venous catheter products include:

• Neostar^®. The Neostar^® Tunneled Central Venous Catheters are among the most well known and trusted names in catheters. The central venous catheters are intended for long-term vascular access, suitable for chemotherapy, infusion of intravenous fluids or drugs, parental nutrition, transfusion or sampling blood products. With single, double and triple lumen configurations, one-piece Y-hubs for mirror smooth transition points and complete tray availability, the Neostar^® is an excellent choice for patients.

ONCOLOGY/SURGERY

Oncology/Surgery includes our RFA, Embolization and IRE product lines.

Radiofrequency Ablation Products

Radiofrequency Ablation (RFA) products use radiofrequency energy to provide a minimally invasive approach to ablating solid cancerous or benign tumors. Our system delivers radiofrequency energy to raise the temperature of cells above 45-50°C, causing cellular death.

The physician inserts the disposable needle electrode device into the target body tissue, typically under ultrasound, computed tomography or magnetic resonance imaging guidance. Once the device is inserted, pushing on the handle of the device causes a group of curved wires to be deployed from the tip of the electrode. When the power is turned on, these wires deliver radiofrequency energy throughout the tumor. In addition, temperature sensors on the tips of the wires measure tissue temperature throughout the procedure.

During the procedure, our system automatically adjusts the amount of energy delivered in order to maintain the temperature necessary to ablate the targeted tissue. For a typical 5cm ablation using our Starburst XLie disposable device, the ablation process takes approximately ten minutes. When the ablation is complete, pulling back on the handle of the device causes the curved wire array to be retracted into the device so it can be removed from the body. Our disposable device cauterizes the tissue along the needle tract, which we believe kills any residual cancer cells that might be removed from the tumor.

Benefits of the RFA System

The benefits of our system include:

• Effective Treatment Option. We believe that our system provides an effective treatment option to liver cancer patients who previously had few options available to effectively address their unresectable liver tumors. Further, our system provides an effective treatment option for patients whose tumors have metastasized to the bone and cause pain that cannot be adequately relieved by other means. In the future, our system may offer patients with other types of tumors a similar treatment option.

• Minimally-Invasive Procedure. The RFA system offers physicians an effective minimally-invasive treatment option with few side effects or complications. Our products can be used in an outpatient procedure that requires only local anesthesia, and patients are typically sent home the same day with a small bandage over the entry site. Alternatively, patients can be treated with just an overnight hospital stay either through a small wound in the skin or laparoscopically through several small incisions. Compared to existing alternatives, we believe our minimally-invasive procedure is cost-effective and can result in reduced hospital stays.

• Proprietary Array Design and Temperature Feedback Provide Procedural Control. Our array design enables the physician to predictably ablate large volumes of targeted tissue. In addition, our temperature feedback feature allows physicians to ensure that the temperature is high enough at the electrode to achieve cell death.

• Repeat Treatments Possible. Cancer is most often a recurrent disease. However, due to the invasive nature of other treatment options, such as surgery, the majority of patients who undergo traditional therapies cannot be retreated in the event that new tumors appear or previously treated tumors reappear. Because of the minimally-invasive nature of our procedure, patients treated with our RFA system can often be retreated.

• Broadly Applicable Technology. Our significant clinical experience with liver tumors and bone tumors, as well as feasibility studies in other organs, indicates that our technology may in the future be broadly applied to the ablative treatment of solid tumors in the lung, breast, uterus, prostate and kidney.

12

While there are numerous benefits of our system, there are some side effects of treatment as well. Published reports on the use of the RFA system indicate low overall complication rates. These include ground-pad burns, which are burns that can occur when there is a concentration of heat at the ground-pad site, bleeding, abscesses and, in cases involving the treatment of bone tumors, fractures and nerve damage. Studies have also shown some recurrence of tumors following treatment with our system. In many cases where tumors recur, however, our procedure can often be repeated. In rare cases, unintentional physician misuse of our system has resulted in patient deaths.

Radiofrequency Ablation Product Technology

Our radiofrequency ablation products are based on proprietary technology used to ablate tissue in a controlled manner. A radiofrequency generator supplies energy through our disposable device placed within the targeted tissue. Our devices contain curved, space-filling arrays of wires that are deployed from the tip to allow the radiofrequency energy to be dispersed throughout the tumor.

Radiofrequency energy supplied by the generator produces ionic agitation, or cellular friction, in the tissue closely surrounding the electrode. This friction produces heat that can be used to predictably ablate volumes of tissue. To effectively ablate tissue, it must be heated to an approximate temperature of 45- 50°C, or 113-122°F.

Our system is designed to permit the physician to set the desired treatment time and temperature at the beginning of the procedure. Once that temperature is reached, our proprietary temperature control technology automatically adjusts the energy supplied from the generator to maintain the optimal temperature within the tissue during the course of the procedure. We believe our system has the potential to provide a more effective ablation than competing technologies by providing critical tissue temperature feedback during the procedure.

Some of our products make use of saline to enhance the ablation process. This saline is used to irrigate the ablation site and is delivered through the curved array of wires in our devices. The use of saline can significantly increase the speed of the ablation treatment and permits ablation of larger tumors.

The RFA system consists of a radiofrequency generator and a family of disposable devices. We also market the HABIB 4X^® resection device under a distribution agreement with EMcision Limited. In addition to the intra-operative (open surgery) device HABIB 4X, AngioDynamics markets a minimally-invasive version of the HABIB 4X device, a Laparoscopic 4X unit, specifically indicated for clinical use in minimally invasive laparascopic surgery (MILS) procedures in surgical specialties such as: Hepato-Biliary, GI, Surgical Oncology, Transplant Surgery and Urology (Partial Nephrectomy Resections).

RFA Disposable Electrodes

Our RFA disposable electrodes all consist of needle shaped electrodes containing curved wire arrays that are deployed into the targeted body tissue. Each device contains several thermocouples, or temperature sensors, which provide feedback to the physician of the tissue temperature during the ablation and allow the generator to automatically adjust the amount of radiofrequency energy so that the desired tissue temperature can be achieved.

Our RFA disposable electrodes are available in different array sizes to allow the physician to create a spherical ablation volume of anywhere from two to seven centimeters. In addition, depending on product line, the devices are available in 10, 12, 15 or 25cm lengths to allow physicians to access tumors that are located more or less deeply within the body. Each RFA disposable device is supplied with one or more ground pads to allow a return path for the flow of radiofrequency energy from the patient back to the generator.

RF Resection Device

We have an exclusive worldwide license with EMcision Limited to sell the HABIB^® 4X bipolar radiofrequency resection device. This product is designed to coagulate a “surgical resection plane” to facilitate a fast dissection with limited blood loss. It is compatible with our Model 1500 and Model 1500X radiofrequency generators.

RFA Generators

All of our generators employ an internal computer to assist the physician in safely and effectively controlling the delivery of radiofrequency during ablation or surgical resection procedures. In addition, each generator has a display to convey information to the physician while using the system. Our Model 1500X generators have the ability, using a laptop computer, to display real-time, color-coded graphs of items such as power, temperature and impedance to aid the user in controlling the system and to collect procedural information for the patient’s record. These generators are designed to have their software changed in the field through the insertion of a small card containing electronic memory circuits.

NanoKnife Products

Our recently introduced NanoKnife™ System is the first commercially available technology platform based on the principles of Irreversible Electroporation (IRE). IRE is for the surgical ablation of soft tissue. IRE utilizes high voltage electrical pulses to permanently open pores in target cell membranes. These permanent pores or nano-scale defects in the cell membranes result in cell death. The treated tissue is then removed by the body’s natural processes in a matter of weeks – mimicking natural cell death. Unlike other ablation technologies, IRE is non-thermal – allowing targeted tissue elimination while sparing critical structures, such as ducts, blood vessels and nerves.

The Nanoknife IRE System consists of two major components: a Low Energy Direct Current (“LEDC”) Generator and needle-like electrode Probes. Up to six (6) electrode Probes can be placed into or around the targeted soft tissue. Once the Probes are in place, the user enters the appropriate parameters for voltage, number of pulses, interval between pulses, and the pulse length into the generator user interface. The generator then delivers a series of short electric pulses between each electrode Probe. The energy delivery is hyperechoic and can be monitored under real-time ultrasound.

Data gathered through bench, preclinical studies, and early human experience, suggest that the Nanoknife IRE System has the following characteristics:

• Spares vital structures. Because IRE is non-thermal, vasculature, nerves and ducts remain intact. IRE enables ablation treatment at or near critical structures, resulting in selective tissue damage.

• Eliminates heat sink issues seen with other ablation modalities. Since IRE is non-thermal, it is not susceptible to non-uniform ablation zones due to heat sinks (in the case of RFA) or heat sources (in the case of cryoablation).

• Real-time imaging during IRE. An IRE ablation can be detected real-time with ultrasound and CT imaging. Moreover, these imaging modalities are not rendered “useless” during the procedure – as is the case with ultrasound with RFA and cryoablation.

• Tissue treated in organs that regenerate may be replaced by normal tissue.

• Minimal to no pain reported by patients following treatment.

Research & Development

Our growth depends in large part on the continuous introduction of new and innovative products, together with ongoing enhancements to our existing products, through internal product development, technology licensing and strategic alliances. We recognize the importance of, and intend to continue to make investments in, research and development. For fiscal 2009, 2008 and 2007, our research and development (“R&D”) expenditures were $17.9 million, $14.4 million, and $20.6 million, respectively, and constituted 9.2%, 8.7%, and 18.3%, respectively, of net sales. A significant portion of our R&D expenses in 2007 related to a charge of $12.1 million for in-process R&D required under purchase accounting rules from our acquisition of RITA. Without this charge, our R&D expenses were approximately 7.5% of net sales in 2007. R&D activities include research, product development, intellectual property and regulatory affairs. We expect that our R&D expenditures will be approximately 10% of net sales in fiscal 2010 primarily due to investment in IRE technology and remain in the range of 8 to 10% of net sales thereafter. However, downturns in our business could cause us to reduce our R&D spending.

Our research and product development teams work closely with our sales force to incorporate customer feedback into our development and design process. We believe that we have a reputation among interventional physicians as a good partner for product development because of our tradition of close physician collaboration, dedicated market focus, responsiveness and execution capabilities for product development and commercialization.

Competition

We encounter significant competition across our product lines and in each market in which our products are sold. These markets are characterized by rapid change resulting from technological advances and scientific discoveries. We face competitors ranging from large manufacturers with multiple business lines to small manufacturers that offer a limited selection of products.

In addition, we compete with providers of other medical therapies, such as pharmaceutical companies, that may offer non-surgical therapies for conditions that currently, or in the future, may be treated using our products. Our primary device competitors include: Biosphere Medical (Direct LC Bead competitor); Boston Scientific Corporation; Cook Medical; Navilyst Medical; Cordis Corporation, a subsidiary of Johnson & Johnson, Inc.; C.R. Bard; Radionics, a division of Integra LifeSciences Corporation; Medical Components, Inc. or Medcomp; Arrow International, a subsidiary of TeleFlex Medical; Smith’s Medical, a subsidiary of Smiths Group plc; EV3, Inc.; Kendall Healthcare, a subsidiary of Covidien; Vascular Solutions; and VNUS Medical, a company recently acquired by Covidien.

Medcomp supplies us with most of our dialysis catheters, but also competes with us by selling other catheters.

Many of our competitors have substantially greater financial, technological, research and development, regulatory, marketing, sales and personnel resources than we do. Competitors may also have greater experience in developing products, obtaining regulatory approvals, and manufacturing and marketing such products. Additionally, competitors may obtain patent protection or regulatory approval or clearance, or achieve product commercialization before us, any of which could materially adversely affect us.

We believe that our products compete primarily on the basis of their quality, ease of use, reliability, physician familiarity and cost-effectiveness. Generally, our products are sold at higher prices than those of our competitors. In the current environment of managed care, which is characterized by economically motivated buyers, consolidation among health care providers, increased competition and declining reimbursement rates, we have been increasingly required to compete on the basis of price. We believe that our continued competitive success will depend upon our ability to develop or acquire scientifically advanced technology, apply our

16

technology cost-effectively across product lines and markets, develop or acquire proprietary products, attract and retain skilled development personnel, obtain patent or other protection for our products, obtain required regulatory and reimbursement approvals, manufacture and successfully market our products either directly or through outside parties and maintain sufficient inventory to meet customer demand.

Sales and Marketing

We focus our sales and marketing efforts on interventional radiologists, vascular surgeons, and interventional and surgical oncologists. There are more than 5,000 interventional radiologists, 2,000 vascular surgeons, and 2,000 interventional and surgical oncologists in the United States. We seek to educate these physicians on the clinical efficacy, performance, ease of use, value and other advantages of our products.

We also involve ourselves in assisting interventional physicians with clinical practice building for outpatient interventional procedures. This can include outpatient practices in vein, dialysis access management, tumor ablation, pain management and broad based interventional procedures.

We promote our products through medical society meetings that are attended by interventional radiologists, vascular surgeons, interventional cardiologists, interventional nephrologists, interventional oncologists and others. Our attendance at these meetings is an important method of communicating with our customers. We receive direct feedback from customers and present new ideas and products at these meetings. As these societies rely on industry participation and support in order to effectively hold these meetings, attendance also reflects our support and commitment to the medical societies.

Backlog

Historically, we ship 95% of products sold in the United States within 48 hours of receipt of the orders, and accordingly our backlog is not significant.

Manufacturing

We own a manufacturing, administrative, engineering and warehouse facility of approximately 104,000 square feet in Queensbury, New York. We also lease a manufacturing facility of approximately 60,000 square feet located in Manchester, Georgia and a 7,000 square foot manufacturing facility in Fremont, CA. We lease a manufacturing facility of approximately 20,000 square feet in the United Kingdom that we acquired in June 2008 in connection with our acquisition of certain assets of Diomed, Ltd. We believe these facilities have sufficient capacity to meet our anticipated manufacturing needs for the next five years.

We manufacture certain proprietary components and products and assemble, inspect, test and package our finished products. By designing and manufacturing many of our products from raw materials, and assembling and testing our subassemblies and products, we believe that we are able to maintain better quality control, ensure compliance with applicable regulatory standards and our internal specifications, and limit outside access to our proprietary technology. We have custom-designed proprietary manufacturing and processing equipment and have developed proprietary enhancements for existing production machinery.

Our management information system includes order entry, invoicing, on-line inventory management, lot traceability, purchasing, shop floor control and shipping and distribution analysis, as well as various accounting-oriented functions. This system enables us to track our products from the inception of an order through all parts of the manufacturing process until the product is delivered to the customer.

We purchase components from third parties. Most of our components are readily available from several supply sources. We also purchase finished products from third parties. One supplier, Medcomp, currently supplies most of our dialysis catheters. Medcomp products accounted for approximately 10% of our net sales for fiscal 2009. To date, we have been able to obtain adequate supplies of all product and components in a timely manner from existing sources.

17

In fiscal 2009, 65% of our product sales were derived from products we manufactured or assembled ourselves, with the balance being derived from products manufactured for us by third parties. Our Queensbury, Manchester, Fremont and Cambridge facilities are registered with the FDA and have been certified to ISO 13485 standards, as well as the CMD/CAS Canadian Medical Device Regulations. ISO 13485 is a quality system standard that satisfies European Union regulatory requirements, thus allowing us to market and sell our products in European Union countries. If we were to lose this certification, we would no longer be able to sell our products in these countries until we made the necessary corrections to our operations or satisfactorily completed an alternate European Union approval route that did not rely on compliance with quality system standards. Our manufacturing facilities are subject to periodic inspections by regulatory authorities to ensure compliance with domestic and non-U.S. regulatory requirements. See “Government Regulation”.

Intellectual Property

As of June 30, 2009, we owned 158 U.S. patents, 120 pending U.S. applications, and 285 foreign issued and pending patents. We also own 41 U.S. registered trademarks and 47 common law trademarks. There are currently 51 registered international trademarks and 5 pending international trademarks.

We believe that our success is dependent, to a large extent, on patent protection and the proprietary nature of our technology. We intend to continue to file and prosecute patent applications for our technology in jurisdictions where we believe that patent protection is effective and advisable, generally in the United States and other appropriate jurisdictions.

Notwithstanding the foregoing, the patent positions of medical device companies, including our company, are uncertain and involve complex and evolving legal and factual questions. The coverage sought in a patent application can be denied or significantly reduced either before or after the patent is issued. Consequently, there can be no assurance that any of our pending patent applications will result in an issued patent. There is also no assurance that any existing or future patent will provide significant protection or commercial advantage, or whether any existing or future patent will be circumvented by a more basic patent, thus requiring us to obtain a license to produce and sell the product. Generally, patent applications can be maintained in secrecy for at least 18 months after their earliest priority date. In addition, publication of discoveries in the scientific or patent literature often lags behind actual discoveries. Therefore, we cannot be certain that we were the first to invent the subject matter covered by each of our pending U.S. patent applications or that we were the first to file non-U.S. patent applications for such subject matter.

If a third party files a patent application relating to an invention claimed in our patent application, we may be required to participate in an interference proceeding declared by the U.S. Patent and Trademark Office to determine who owns the patent. Such proceeding could involve substantial uncertainties and cost, even if the eventual outcome is favorable to us. There can be no assurance that our patents, if issued, would be upheld as valid in court.

Third parties may claim that our products infringe on their patents and other intellectual property rights. Some companies in the medical device industry have used intellectual property infringement litigation to gain a competitive advantage. If a competitor were to challenge our patents, licenses or other intellectual property rights, or assert that our products infringe its patent or other intellectual property rights, we could incur substantial litigation costs, be forced to make expensive changes to our product designs, license rights in order to continue manufacturing and selling our products, or pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consume our financial resources but also divert our management’s time and effort. Such claims could also cause our customers or potential customers to defer or limit their purchase or use of the affected products until resolution of the claim.

In January 2004, Diomed filed an action against us alleging that our VenaCure products for the treatment of varicose veins infringed a patent held by Diomed for a laser system that competes with our VenaCure products. In March 2007, a jury ruled in Diomed’s favor and awarded compensatory damages totaling $9.71 million

18

following an initial appeal. We disputed the infringement verdict on multiple grounds and on June 20, 2007, filed an appeal in the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. On July 2, 2007, the judge for the Federal District in Boston, Massachusetts, issued an injunction prohibiting us from selling our original bare fiber VenaCure product. On March 14, 2008, Diomed commenced Chapter 11 bankruptcy proceedings. On April 2, 2008, we entered into a settlement agreement with Diomed and we paid $7 million resolving the patent disputes.

In October 2005, VNUS Medical Technologies filed an action against us, Diomed and another defendant alleging, among other things, that the manufacture, use and sale of our VenaCure products infringed several patents held by VNUS and seeking injunctive relief and compensatory and treble damages, reasonable attorney fees, costs and pre-judgment interest. On June 3, 2008, we entered into an agreement with VNUS settling all patent litigation between us and VNUS. Under the terms of the settlement agreement, we paid VNUS approximately $6.8 million in June 2008 and agreed to pay a quarterly royalty on U.S. sales of our NeverTouch™ and VenaCure^® and Diomed products from June 1, 2008 until the expiration date of VNUS’ applicable patents. In exchange, VNUS granted us a non-exclusive and non-sublicensable license to VNUS’ applicable patents for use in endovenous laser therapy.

On July 29, 2009, we filed a complaint in the United States District Court for the District of Delaware against Vascular Solutions, Inc. (NASDAQ: VASC). The complaint alleges that Vascular Solutions’ Vari-Lase Bright-Tip fiber product line infringes on claims of two of AngioDynamics’ patents, US 7,273,478 and US 7,559,329. These patents relate to methods of treating varicose veins using endovenous laser treatments.

See Item 3 of this report for additional details.

We rely on trade secret protection for certain unpatented aspects of our proprietary technology. There can be no assurance that others will not independently develop or otherwise acquire substantially equivalent proprietary information or techniques, that others will not gain access to our proprietary technology or disclose such technology, or that we can meaningfully protect our trade secrets. We have a policy of requiring key employees and consultants to execute confidentiality agreements upon the commencement of an employment or consulting relationship with us. Our confidentiality agreements also require our employees to assign to us all rights to any inventions made or conceived during their employment with us. We also generally require our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer or disclosure of confidential information or inventions.

The laws of foreign countries generally do not protect our proprietary rights to the same extent, as do the laws of the United States. In addition, we may experience more difficulty enforcing our proprietary rights in certain foreign jurisdictions.

Government Regulation

The products we manufacture and market are subject to regulation by the FDA under the Federal Food, Drug, and Cosmetic Act, or FDCA, and, in some instances, state authorities and foreign governments.

United States FDA Regulation

Before a new medical device can be introduced into the market, a manufacturer generally must obtain marketing clearance or approval from the FDA through either a 510(k) submission (a premarket notification) or a premarket approval application, or PMA.

The 510(k) procedure is less rigorous than the PMA procedure, but is available only in particular circumstances. The 510(k) clearance procedure is available only if a manufacturer can establish that its device is “substantially equivalent” in intended use and in safety and effectiveness to a “predicate device,” which is a

19

legally marketed device with 510(k) clearance in class I or II or grandfather status based upon commercial distribution on or before May 28, 1976. After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new 510(k) clearance or could require a PMA approval. The 510(k) clearance procedure generally takes from four to 12 months from the time of submission, but may take longer. In some cases, supporting clinical data may be required. The FDA may determine that a new or modified device is not substantially equivalent to a predicate device or may require that additional information, including clinical data, be submitted before a determination is made, either of which could significantly delay the introduction of new or modified device products. If a product does not satisfy the criteria of substantial equivalence, it is placed in class III and premarket approval is required prior to the introduction of that product into the market.

The PMA application procedure is more comprehensive than the 510(k) procedure and typically takes several years to complete. The PMA application must be supported by scientific evidence providing pre-clinical and clinical data relating to the safety and efficacy of the device and must include other information about the device and its components, design, manufacturing and labeling. The FDA will approve a PMA application only if a reasonable assurance that the device is safe and effective for its intended use can be provided. As part of the PMA application review, the FDA will inspect the manufacturer’s facilities for compliance with its Quality System Regulation, or QSR. As part of the PMA approval the FDA may place restrictions on the device, such as requiring additional patient follow-up for an indefinite period of time. If the FDA’s evaluation of the PMA application or the manufacturing facility is not favorable, the FDA may deny approval of the PMA application or issue a “not approvable” letter. The FDA may also require additional clinical trials, which can delay the PMA approval process by several years. After the PMA is approved, if significant changes are made to a device, its manufacturing or labeling, a PMA supplement containing additional information must be filed for prior FDA approval.

Historically, our products have been introduced into the market using the 510(k) procedure and we have never had to use the more rigorous PMA procedure.

The FDA clearance and approval processes for a medical device are expensive, uncertain and lengthy. There can be no assurance that we will be able to obtain necessary regulatory clearances or approvals for any product on a timely basis or at all. Delays in receipt of or failure to receive such clearances or approvals, the loss of previously received clearances or approvals, or the failure to comply with existing or future regulatory requirements could have a material adverse effect on our business, financial condition and results of operations.

After a product is placed on the market, the product and its manufacturer are subject to pervasive and continuing regulation by the FDA. The FDA enforces these requirements by inspection and market surveillance. Our suppliers also may be subject to FDA inspection. We must therefore continue to spend time, money and effort to maintain compliance. Among other things, we must comply with the Medical Device Reporting regulation, which requires that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were to recur. We must also comply with the FDA’s corrections and removal reporting regulation, which requires that manufacturers report to the FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by a device or to remedy a violation of the FDCA that may present a risk to health. The labeling and promotion activities for devices are subject to scrutiny by the FDA and, in certain instances, by the Federal Trade Commission. The FDA actively enforces regulations prohibiting the marketing of devices for unapproved new uses.

The devices manufactured by us also are subject to the QSR, which imposes elaborate testing, control, documentation and other quality assurance procedures. Every phase of production, including raw materials, components and subassemblies, manufacturing, testing, quality control, labeling, tracing of consignees after distribution and follow-up and reporting of complaint information is governed by the FDA’s QSR. Device manufacturers are required to register their facilities and list their products with the FDA and certain state

20

agencies. The FDA periodically inspects manufacturing facilities and, if there are alleged violations, the operator of a facility must correct them or satisfactorily demonstrate the absence of the violations or face regulatory action.

We are subject to inspection and marketing surveillance by the FDA to determine our compliance with all regulatory requirements. Recently, the FDA has placed an increased emphasis on enforcement of the QSR and other postmarket regulatory requirements. Non-compliance with applicable FDA requirements can result in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the FDA to grant marketing approvals, withdrawal of marketing approvals, a recommendation by the FDA to disallow us to enter into government contracts, and criminal prosecutions. The FDA also has the authority to request repair, replacement or refund of the cost of any device manufactured or distributed by us.

Other

We and our products are also subject to a variety of state and local laws in those jurisdictions where our products are or will be marketed, and federal, state and local laws relating to matters such as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal of hazardous or potentially hazardous substances. For example, we are registered with the Office of the Professions of the New York State Department of Education. We are also subject to various federal and state laws governing our relationships with the physicians and others who purchase or make referrals for our products. For instance, federal law prohibits payments of any form that are intended to induce a referral for any item payable under Medicare, Medicaid or any other federal healthcare program. Many states have similar laws. There can be no assurance that we will not be required to incur significant costs to comply with such laws and regulations now or in the future or that such laws or regulations will not have a material adverse effect upon our ability to do business.

Non-U.S. Regulation

Internationally, all of our current products are considered medical devices under applicable regulatory regimes, and we anticipate that this will be true for all of our future products. Sales of medical devices are subject to regulatory requirements in many countries. The regulatory review process may vary greatly from country to country. For example, the European Union has adopted numerous directives and standards relating to medical devices regulating their design, manufacture, clinical trials, labeling and adverse event reporting. Devices that comply with those requirements are entitled to bear a Conformité Européenne, or CE Mark, indicating that the device conforms to the essential requirements of the applicable directives and can be commercially distributed in countries that are members of the European Union.

In some cases, we rely on our non-U.S. distributors to obtain regulatory approvals, complete product registrations, comply with clinical trial requirements and complete those steps that are customarily taken in the applicable jurisdictions.

Non-U.S. sales of medical devices manufactured in the United States that are not approved or cleared by the FDA for use in the United States, or are banned or deviate from lawful performance standards, are subject to FDA export requirements. Before exporting such products to a foreign country, we must first comply with the FDA’s regulatory procedures for exporting unapproved devices.

There can be no assurance that new laws or regulations regarding the release or sale of medical devices will not delay or prevent sale of our current or future products.

21

Third-Party Reimbursement

United States

Our products are used in medical procedures generally covered by government or private health plans. Accordingly, our sales and the prices we charge for our products depend significantly on the extent to which those third-party payors, such as Medicare, Medicaid and other government programs and private insurance plans, cover our products and the procedures performed with them.

In general, a third-party payor only covers a medical product or procedure when the plan administrator is satisfied that the product or procedure improves health outcomes, including quality of life or functional ability, in a safe and cost-effective manner. Even if a device has received clearance or approval for marketing by the FDA, there is no assurance that third-party payors will cover the cost of the device and related procedures.

In many instances, third-party payors use price schedules that do not vary to reflect the cost of the products and equipment used in performing those procedures. In other instances, payment or reimbursement is separately available for the products and equipment used, in addition to payment or reimbursement for the procedure itself. Even if coverage is available, third-party payors may place restrictions on the circumstances where they provide coverage or may offer reimbursement that is not sufficient to cover the cost of our products. Many competing products are less expensive than ours. Therefore, although coverage may be available for our products and the related procedures, the levels of approved coverage may not be sufficient to justify using our products instead of those of competitors.

Third-party payors are increasingly challenging the prices charged for medical products and procedures and, where a reimbursement model is used, introducing maximum reimbursements for the procedures they cover. We believe that the minimally invasive procedures in which our products are used are generally less costly than open surgery. However, there is no guarantee that these procedures will be reimbursed. Third-party payors may not consider these minimally invasive procedures to be cost-effective and may therefore refuse to authorize coverage.

Third-party payors who cover the cost of medical products or equipment, in addition to allowing a general charge for the procedure, often maintain lists of exclusive suppliers or approved lists of products deemed to be cost-effective. Authorization from those third-party payors is required prior to using products that are not on these lists as a condition of reimbursement. If our products are not on the approved lists, healthcare providers must determine if the additional cost and effort required to obtain prior authorization, and the uncertainty of actually obtaining coverage, is justified by any perceived clinical benefits from using our products.

Finally, the advent of contracted fixed rates per procedure has made it difficult to receive reimbursement for disposable products, even if the use of these products improves clinical outcomes. In addition, many third-party payors are moving to managed care systems in which providers contract to provide comprehensive healthcare for a fixed cost per person. Managed care providers often attempt to control the cost of healthcare by authorizing fewer elective surgical procedures. Under current prospective payment systems, such as the diagnosis related group system and the hospital out-patient prospective payment system, both of which are used by Medicare and in many managed care systems used by private third-party payors, the cost of our products will be incorporated into the overall cost of a procedure and not be separately reimbursed. As a result, we cannot be certain that hospital administrators and physicians will purchase our products, despite the clinical benefits and opportunity for cost savings that we believe can be derived from their use.

If hospitals and physicians cannot obtain adequate reimbursement for our products or the procedures in which they are used, our business, financial condition, results of operations, and cash flows could suffer a material adverse impact.

22

Non-U.S.

Our success in non-U.S. markets will depend largely upon the availability of reimbursement from the third-party payors through which healthcare providers are paid in those markets. Reimbursement and healthcare payment systems in non-U.S. markets vary significantly by country. The main types of healthcare payment systems are government sponsored healthcare and private insurance. Reimbursement approval must be obtained individually in each country in which our products are marketed. Outside the United States, we generally rely on our distributors to obtain reimbursement approval in the countries in which they will sell our products. There can be no assurance that reimbursement approvals will be received.

Insurance

Our product liability insurance coverage is limited to a maximum of $10,000,000 per product liability claim and an aggregate policy limit of $10,000,000, subject to deductibles of $250,000 per occurrence and $1,250,000 in the aggregate. The policy covers, subject to policy conditions and exclusions, claims of bodily injury and property damage from any product sold or manufactured by us.

There is no assurance that this level of coverage is adequate. We may not be able to sustain or maintain this level of coverage and cannot assure you that adequate insurance coverage will be available on commercially reasonable terms or at all. A successful product liability claim or other claim with respect to uninsured or underinsured liabilities could have a material adverse effect on our business.

Environmental

We are subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain hazardous and potentially hazardous substances used in connection with our operations. Although we believe that we have complied with these laws and regulations in all material respects and, to date, have not been required to take any action to correct any noncompliance, there can be no assurance that we will not be required to incur significant costs to comply with environmental regulations in the future.

Employees

As of May 31, 2009, we had 715 full-time employees, including 377 in manufacturing; 81 in research, product development and regulatory approval/quality assurance; 201 in sales and marketing; and 56 in administration. None of our employees are represented by a labor union, and we have never experienced a work stoppage.

23

Item 1A. Risk Factors

Our financial and operating results are subject to a number of factors, many of which are not within our control. These factors include the following:

If we fail to develop or market new products and enhance existing products, we could lose market share to our competitors and our results of operations could suffer.

The market for interventional devices is characterized by rapid technological change, new product introductions, technological improvements, changes in physician requirements and evolving industry standards. To be successful, we must continue to develop and commercialize new products and to enhance versions of our existing products. Our products are technologically complex and require significant research, planning, design, development and testing before they may be marketed. This process generally takes at least 12 to 18 months from initial concept and may take up to several years. In addition, product life cycles are relatively short because medical device manufacturers continually develop smaller, more effective and less expensive versions of existing devices in response to physician demand.

Our success in developing and commercializing new and enhanced versions of our products is affected by our ability to:

• recruit engineers;

• timely and accurately identify new market trends;

• accurately assess customer needs;

• minimize the time and costs required to obtain regulatory clearance or approval;

• adopt competitive pricing;

• timely manufacture and deliver products;

• accurately predict and control costs associated with the development, manufacturing and support of our products; and

• anticipate and compete effectively with our competitors’ efforts.

Market acceptance of our products depends in part on our ability to demonstrate that our products are cost-effective and easier to use, as well as offer technological advantages. Additionally, we may experience design, manufacturing, marketing or other difficulties that could delay or prevent our development, introduction or marketing of new products or new versions of our existing products. As a result of such difficulties and delays, our development expenses may increase and, as a consequence, our results of operations could suffer.

We face intense competition in the medical device industry. We may be unable to compete effectively with respect to technological innovation and price which may have an adverse effect on our revenues, financial condition or results of operations.

The markets for interventional devices are highly competitive, and we expect competition to continue to intensify. We may not be able to compete effectively, and we may lose market share to our competitors. The principal competitors in the markets for our products currently include: Biosphere Medical (Direct LC Bead competitor); Boston Scientific Corporation; Cook Medical; Navilyst Medical; Cordis Corporation, a subsidiary of Johnson & Johnson, Inc.; C.R. Bard Inc.; Radionics, a division of Integra LifeSciences Corporation; Medical Components, Inc., or Medcomp; Arrow International, a subsidiary of TeleFlex Medical; Smith’s Medical, a subsidiary of Smiths Group plc; EV3, Inc.; Kendall Healthcare, a subsidiary of Covidien; and VNUS Medical Technologies, Inc., a company recently acquired by Covidien. Many of our competitors have substantially greater:

• financial and other resources to devote to product acquisitions, research and development, marketing and manufacturing;

24

• variety of products;

• technical capabilities;

• history of developing and introducing new products;

• patent portfolios that may present an obstacle to our conduct of business;

• name recognition; and

• distribution networks and in-house sales forces.

Our competitors may succeed in developing technologies and products earlier, in obtaining patent protection or regulatory clearance earlier, or in commercializing new products or technologies more rapidly than us. Our competitors may also develop products and technologies that are superior to those we are developing or that otherwise could render our products obsolete or noncompetitive. In addition, we may face competition from providers of other medical therapies, such as pharmaceutical companies, that may offer non-surgical therapies for conditions that are currently or in the future may be treated using our products. Our products are generally sold at higher prices than those of our competitors. However, in the current environment of managed care, which is characterized by economically motivated buyers, consolidation among healthcare providers, increased competition and declining reimbursement rates, we are increasingly being required to compete on the basis of price. If we are not able to compete effectively, our market share and revenues may decline.

Development and sales of our IRE products are dependent on a number of factors beyond our control, and our inability to successfully complete our research and development, design and marketing strategy with respect to IRE may adversely affect our business, financial condition and results of operations.

A significant aspect of our growth strategy is the development of our IRE products, including NanoKnife. Our IRE products are currently in development and there can be no guarantee that we will be able to develop and manufacture IRE products on commercially favorable terms, or at all. IRE is a developing technology and the inability of IRE to achieve clinical acceptance could severely limit the sales of IRE products.

We currently have FDA 510(k) clearance to market IRE products for soft tissue ablation. If we are not able to secure FDA marketing approval for additional or more specific indications, through 510(k) clearance, pre-market approval or otherwise, our ability to market our IRE products will be restricted which may have an adverse effect on our business, financial condition and results of operations.

We may be exposed to risks associated with acquisitions, including integration risks and risks associated with methods of financing and the impact of accounting treatment. Accordingly, completed acquisitions may not enhance our financial position or results of operations.

Part of our growth strategy is to acquire businesses and technologies that are complementary to ours. There is no assurance that acquisition opportunities will be available on acceptable terms or at all or that we will be able to obtain necessary financing or regulatory approvals. Any acquisitions that we do undertake would be accompanied by the risks commonly encountered in acquisitions, including the:

• potential disruption of our business while we evaluate opportunities, complete acquisitions and develop and implement new business strategies to take advantage of these opportunities;

• inability of our management to maximize our financial and strategic position by incorporating an acquired technology or business into our existing offerings;

• difficulty of maintaining uniform standards, controls, procedures and policies;

• difficulty of assimilating the operations and personnel of acquired businesses;

25

• potential loss of key employees of acquired businesses, and the impairment of relationships with employees and customers as a result of changes in management; and

• uncertainty as to the long-term success of any acquisitions we may make.

There is no assurance that any completed acquisition will be accretive to our margins or profits in the short term or in the long term. If we proceed with one or more significant acquisitions in which the consideration consists of cash, a substantial portion of our available cash could be used to consummate the acquisitions. If we consummate one or more acquisitions in which the consideration consists of capital stock, our stockholders could suffer significant dilution of their interest in us. In addition, we could incur or assume significant amounts of indebtedness in connection with acquisitions. Further, acquisitions could also result in significant goodwill and/or amortization charges for acquired businesses or technologies.

If we fail to adequately protect our intellectual property rights, we may not be able to generate revenues from new or existing products and our business may suffer.

Our success depends in part on obtaining, maintaining and enforcing our patents, trademarks and other proprietary rights, and our ability to avoid infringing the proprietary rights of others. We take precautionary steps to protect our technological advantages and intellectual property. We rely upon patent, trade secret, copyright, know-how and trademark laws, as well as license agreements and contractual provisions, to establish our intellectual property rights and protect our products. However, no assurances can be made that any pending or future patent applications will result in the issuance of patents, that any current or future patents issued to, or licensed by, us will not be challenged or circumvented by our competitors, or that our patents will not be found invalid.

Additionally, we may not be able to effectively protect our rights in unpatented technology, trade secrets and confidential information. Although we require our new employees, consultants and corporate partners to execute confidentiality agreements, these agreements may not provide effective protection of our information or, in the event of unauthorized use or disclosure, may not provide adequate remedies.

If we are not able to adequately protect our intellectual property, our market share, financial condition and results of operations may suffer.

If third parties claim that our products infringe their intellectual property rights, we may be forced to expend significant financial resources and management time defending against such actions and our financial condition and our results of operations could suffer.

Third parties may claim that our products infringe their patents and other intellectual property rights. Identifying third-party patent rights can be particularly difficult because, in general, patent applications can be maintained in secrecy for at least 18 months after their earliest priority date. Some companies in the medical device industry have used intellectual property infringement litigation to gain a competitive advantage. If a competitor were to challenge our patents, licenses or other intellectual property rights, or assert that our products infringe its patent or other intellectual property rights, we could incur substantial litigation costs, be forced to make expensive changes to our product design, pay royalties or other fees to license rights in order to continue manufacturing and selling our products, or pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consume our financial resources but also divert our management’s time and effort. Such claims could also cause our customers or potential customers to purchase competitors’ products or defer or limit their purchase or use of our affected products until resolution of the claim.

In January 2004, Diomed filed an action against us alleging that our VenaCure products for the treatment of varicose veins infringed a patent held by Diomed for a laser system that competes with our VenaCure products. In March 2007, a jury ruled in Diomed’s favor and awarded compensatory damages of $9.71 million. We

26

disputed the infringement verdict on multiple grounds and on June 20, 2007, filed an appeal in the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. On July 2, 2007, the judge for the Federal District in Boston, Massachusetts, issued an injunction prohibiting us from selling our original bare fiber VenaCure product. On March 14, 2008, Diomed commenced Chapter 11 bankruptcy proceedings. On April 2, 2008, we entered into a settlement agreement with Diomed and paid $7 million to resolve the patent disputes.

In October 2005, VNUS Medical Technologies filed an action against us, Diomed and another defendant alleging, among other things, that the manufacture, use and sale of our VenaCure products infringed several patents held by VNUS and seeking injunctive relief and compensatory and treble damages, reasonable attorney’s fees, costs and pre-judgment interest. On June 3, 2008, we entered into an agreement with VNUS settling all patent litigation between us and VNUS. Under the terms of the settlement agreement, we paid VNUS approximately $6.8 million and agreed to pay a quarterly royalty on our U.S. sales of our NeverTouch™ and VenaCure^® and Diomed products from June 1, 2008 until the expiration date of VNUS’ applicable patents. In exchange, VNUS granted us a non-exclusive and non-sublicensable license to VNUS’ applicable patents for use in endovenous laser therapy.

We are dependent on single and limited source suppliers which subjects our business and results of operations to risks of supplier business interruptions.

We currently purchase significant amounts of several key products and product components from single and limited source suppliers and anticipate that we will do so for future products as well. For fiscal 2009, approximately 35% of our product sales were derived from sales of products manufactured for us by third parties. Our principal single source supplier, Medcomp, supplies us with most of our dialysis catheters, which accounted for about 10% of our net sales in fiscal 2009. Medcomp also competes with us by selling catheters that we do not purchase from them.

Any delays in delivery of or shortages in those or other products and components could interrupt and delay manufacturing of our products and result in the cancellation of orders for our products. Any or all of these suppliers could discontinue the manufacture or supply of these products and components at any time. Due to FDA and other business considerations, we may not be able to identify and integrate alternative sources of supply in a timely fashion or at all. Any transition to alternate suppliers may result in production delays and increased costs and may limit our ability to deliver products to our customers. Furthermore, if we are unable to identify alternative sources of supply, we would have to modify our products to use substitute components, which may cause delays in shipments, increased design and manufacturing costs and increased prices for our products.

Current economic instability could adversely affect our operations.

Financial markets and the economies in the United States and internationally have been experiencing a period of upheaval characterized by the bankruptcy, failure, collapse or sale of various financial institutions, severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. This has resulted in severely diminished liquidity and credit availability in the market, which could impair our ability to access capital if required or adversely affect our operations. Similarly, our customers and suppliers may experience financial difficulties or be unable to borrow money to fund their operations which may adversely impact their ability or decision to purchase our products, particularly capital equipment, or to pay for our products they do purchase on a timely basis, if at all.

The economic downturn may also, among other things, create downward pressure on the pricing of our products, increase the sales cycle of certain products and slow the adoption of new technology, any of which could have an adverse effect on our business, financial position and results of operations.

27

Our industry is experiencing greater scrutiny and regulation by governmental authorities, which has led to certain costs and business distractions as we respond to inquiries and comply with new regulations, and may lead to greater governmental regulation in the future.

Our medical devices and our business activities are subject to rigorous regulation by the FDA and numerous other federal, state and foreign governmental authorities. These authorities and members of Congress have been increasing their scrutiny of our industry. In addition, certain states, including Massachusetts, have recently passed or are considering legislation restricting our interactions with health care providers and requiring disclosure of many payments to them. The federal government has recently introduced similar legislation, which may or may not preempt state laws. Recent Supreme Court case law has clarified that the FDA’s authority over medical devices preempts state tort laws, but legislation has been introduced at the federal level to allow state intervention, which could lead to increased and inconsistent regulation at the state level. We anticipate that the government will continue to scrutinize our industry closely, and that additional regulation by governmental authorities may increase compliance costs, exposure to litigation and other adverse effects to our operations.

Consolidation in the healthcare industry could have an adverse effect on our revenues and results of operations.

Many healthcare industry companies, including medical device companies, are consolidating to create new companies with greater market power. As the healthcare industry consolidates, competition to provide goods and services to industry participants will become more intense. These industry participants may try to use their market power to negotiate price concessions or reductions for medical devices that incorporate components produced by us. If we are forced to reduce our prices because of consolidation in the healthcare industry, our revenues would decrease and our consolidated earnings, financial condition, or cash flow would suffer.

Healthcare policy changes, including pending proposals to reform the U.S. healthcare system, may have a material adverse effect on us.

Healthcare costs have risen significantly over the past decade. There have been, and continue to be, proposals by legislators, regulators, and third-party payors to keep these costs down. Certain proposals, if passed, would impose limitations on the prices we will be able to charge for our products, or the amounts of reimbursement available for our products from governmental agencies or third-party payors. These limitations could have a material adverse effect on our financial position and results of operations.

Recently, the President and members of Congress have proposed significant reforms to the U.S. healthcare system. Both the U.S. Senate and House of Representatives have conducted hearings about U.S. healthcare reform. We cannot predict what healthcare initiatives, if any, will be implemented at the federal or state level, or the effect any future legislation or regulation will have on us. However, an expansion in government’s role in the U.S. healthcare industry may lower reimbursements for our products, reduce medical procedure volumes and adversely affect our business, possibly materially.

If we do not maintain our reputation with interventional physicians, our growth will be limited and our business could be harmed.

Physicians typically influence the medical device purchasing decisions of the hospitals and other healthcare institutions in which they practice. Consequently, our reputation with interventional physicians is critical to our continued growth. We believe that we have built a positive reputation based on the quality of our products, our physician-driven product development efforts, our marketing and training efforts and our presence at medical society meetings. Any actual or perceived diminution in the quality of our products, or our failure or inability to maintain these other efforts, could damage our reputation with interventional physicians and cause our growth to be limited and our business to be harmed.

28

Our business could be harmed if we lose the services of our key personnel.

Our business depends upon our ability to attract and retain highly qualified personnel, including managerial, sales and technical personnel. We compete for key personnel with other companies, healthcare institutions, academic institutions, government entities and other organizations. We do not have written employment agreements with our executive officers other than our CEO. Our ability to maintain and expand our business may be impaired if we are unable to retain our current key personnel or hire or retain other qualified personnel in the future.

Undetected defects may increase our costs and impair the market acceptance of our products.

Our products have occasionally contained, and may in the future contain, undetected defects. When these problems occur, we must divert the attention of our engineering personnel to address them. There is no assurance that we will not incur warranty or repair costs, be subject to liability claims for damages related to product defects, or experience manufacturing, shipping or other delays or interruptions as a result of these defects in the future. Our insurance policies may not provide sufficient protection should a claim be asserted. In addition, the occurrence of defects may result in significant customer relations problems and injury to our reputation, and may impair market acceptance of our products.

If a product liability claim is brought against us or our product liability insurance coverage is inadequate, our business could be harmed.

The design, manufacture and marketing of the types of medical devices we sell entail an inherent risk of product liability. Our products are used by physicians to treat seriously ill patients. We are periodically subject to product liability claims, and patients or customers may in the future bring claims in a number of circumstances and for a number of reasons, including if our products were misused, if a component of our product fails, if their manufacture or design was flawed, if they produced unsatisfactory results or if the instructions for use and operating manuals and disclosure of product related risks for our products were found to be inadequate. In addition, individuals or groups seeking to represent a class may file suit against us. The outcome of litigation, particularly class action lawsuits, is difficult to assess or quantify. Plaintiffs in these types of lawsuits often seek recovery of very large or indeterminate amounts, including not only actual damages, but also punitive damages. The magnitude of the potential losses relating to these lawsuits may remain unknown for substantial periods of time.

We carry a product liability policy with a limit of $10 million per product liability claim and an aggregate policy limit of $10 million, subject to deductibles of $250,000 per occurrence and $1,250,000 in the aggregate. We believe, based on claims made against us in the past, our existing product liability insurance coverage is reasonably adequate to protect us from any liabilities we might incur. However, there is no assurance that this coverage will be sufficient to satisfy any claim made against us. In addition, we may not be able to maintain adequate coverage at a reasonable cost and on reasonable terms, if at all. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing any coverage in the future. Additionally, if one or more product liability claims is brought against us for uninsured liabilities or is in excess of our insurance coverage, our financial condition and results of operations could be negatively impacted. Further, such claims may require us to recall some of our products, which could result in significant costs to us and could divert management’s attention from our business.

Changes in reimbursement levels by governmental or other third-party payors for procedures using our products may cause our revenues to decline.

Our products are purchased principally by hospitals or physicians which typically bill various third-party payors, such as governmental programs (e.g. Medicare, Medicaid and comparable foreign programs), private insurance plans and managed care plans, for the healthcare services provided to their patients. The ability of our customers to obtain appropriate reimbursement for products and services from third-party payors is critical to the

29

success of medical device companies because it affects which products customers purchase and the prices they are willing to pay. Reimbursement varies by country and can significantly impact the acceptance of new technology. Implementation of healthcare reforms in the United States and in other countries may limit, reduce or eliminate reimbursement for our products and adversely affect both our pricing flexibility and the demand for our products. Even when we develop a promising new product, we may find limited demand for the product unless reimbursement approval is obtained from private and governmental third party payors.

Third-party payors have adopted, and are continuing to adopt, a number of healthcare policies intended to curb rising healthcare costs. These policies include:

• controls on government-funded reimbursement for healthcare services and price controls on medical products and services providers;

• challenges to the pricing of medical procedures or limits or prohibitions on reimbursement for specific devices and therapies through other means; and

• the introduction of managed care systems in which healthcare providers contract to provide comprehensive healthcare for a fixed cost per person.

We are unable to predict whether federal, state or local healthcare reform legislation or regulation affecting our business may be proposed or enacted in the future, or what effect any such legislation or regulation would have on our business. Changes in healthcare systems in the United States or elsewhere in a manner that significantly reduces reimbursement for procedures using our medical devices or denies coverage for these procedures, or adverse decisions relating to our products by administrators of these systems in coverage or reimbursement issues, would have an adverse impact on the acceptance of our products and the prices which our customers are willing to pay for them.

If we cannot obtain and maintain marketing clearance or approval from governmental agencies, we will not be able to sell our products.

Our products are medical devices that are subject to extensive regulation in the United States and in the foreign countries in which they are sold. Unless an exemption applies, each medical device that we wish to market in the United States must receive either 510(k) clearance or premarket approval from the U.S. Food and Drug Administration, or the FDA, before the product can be sold. Either process can be lengthy and expensive. The FDA’s 510(k) clearance procedure, also known as “premarket notification,” is the process we have used for our current products. This process usually takes from four to 12 months from the date the premarket notification is submitted to the FDA, but may take significantly longer. Although we have obtained 510(k) clearances for our current products, our clearances may be revoked by the FDA if safety or effectiveness problems develop with the devices. The premarket approval process is much more costly, lengthy and uncertain. It generally takes from one to three years from the date the application is submitted to, and filed with, the FDA, and may take even longer. Regulatory regimes in other countries similarly require approval or clearance prior to our marketing or selling products in those countries. We rely on our distributors to obtain regulatory clearances or approvals of our products outside of the United States. If we are unable to obtain additional clearances or approvals needed to market existing or new products in the United States or elsewhere or obtain these clearances or approvals in a timely fashion or at all, or if our existing clearances are revoked, our revenues and profitability may decline.

Modifications to our current products may require new marketing clearances or approvals or require us to cease marketing or recall the modified products until such clearances or approvals are obtained.

Any modification to an FDA-cleared medical device that could significantly affect its safety or effectiveness, or that would constitute a major change or modification in its intended use, requires a new FDA 510(k) clearance or, possibly, a premarket approval. The FDA requires every manufacturer to make its own determination as to whether a modification requires a new 510(k) clearance or premarket approval, but the FDA may review and disagree with any decision reached by the manufacturer. We have modified aspects of some of

30

our devices since receiving regulatory clearance. We believed that some of these modifications did not require new 510(k) clearance or premarket approval and, therefore, we did not seek new 510(k) clearances or premarket approvals. In the future, we may make additional modifications to our products after they have received FDA clearance or approval and, in appropriate circumstances, determine that new clearance or approval is unnecessary. Regulations in other countries in which we market or sell, or propose to market or sell, our products may also require that we make judgments about changes to our products and whether or not those changes are such that regulatory approval or clearance should be obtained. In the United States and elsewhere, regulatory authorities may disagree with our past or future decisions not to seek new clearance or approval and may require us to obtain clearance or approval for modifications to our products. If that were to occur for a previously cleared or approved product, we may be required to cease marketing or recall the modified device until we obtain the necessary clearance or approval. Under these circumstances, we may also be subject to significant regulatory fines or other penalties. If any of the foregoing were to occur, our financial condition and results of operations could be negatively impacted.

If we or some of our suppliers fail to comply with the FDA’s Quality System Regulation, or QSR, and other applicable postmarket requirements, our manufacturing operations could be disrupted, our product sales and profitability could suffer, and we may be subject to a wide variety of FDA enforcement actions.

After a device is placed on the market, numerous regulatory requirements apply. We are subject to inspection and marketing surveillance by the FDA to determine our compliance with all regulatory requirements. Our failure to comply with applicable regulatory requirements could result in the FDA or a court instituting a wide variety of enforcement actions against us, including a public warning letter; an order to shut-down some or all manufacturing operations; a recall of products; fines or civil penalties; seizure or detention of our products; refusing our requests for 510(k) clearance or a premarket approval, or PMA, of new or modified products; withdrawing 510(k) clearance or PMA approvals already granted to us; and criminal prosecution.

Our manufacturing processes and those of some of our suppliers must comply with the FDA’s Quality System Regulation, or QSR, which governs the methods used in, and the facilities and controls used for, the design, testing, manufacture, control, quality assurance, installation, servicing, labeling, packaging, storage and shipping of medical devices. The FDA enforces the QSR through unannounced inspections. If we or one of our suppliers fails a QSR inspection, or if a corrective action plan adopted by us or one of our suppliers is not sufficient, the FDA may bring an enforcement action, and our operations could be disrupted and our manufacturing delayed. We are also subject to the FDA’s general prohibition against promoting our products for unapproved or “off-label” uses, the FDA’s adverse event reporting requirements and the FDA’s reporting requirements for field correction or product removals. The FDA has recently placed increased emphasis on its scrutiny of compliance with the QSR and these other postmarket requirements.

If we or one of our suppliers violate the FDA’s requirements or fail to take adequate corrective action in response to any significant compliance issue raised by the FDA, the FDA can take various enforcement actions which could cause our product sales and profitability to suffer.

In addition, most other countries require us and our suppliers to comply with manufacturing and quality assurance standards for medical devices that are similar to those in force in the United States before marketing and selling our products in those countries. If we or our suppliers should fail to do so, we would lose our ability to market and sell our products in those countries.

Even after receiving regulatory clearance or approval, our products may be subject to product recalls, which may harm our reputation and divert managerial and financial resources.

The FDA and similar governmental authorities in other countries have the authority to order mandatory recall of our products or order their removal from the market if there are material deficiencies or defects in design, manufacture, installation, servicing or labeling of the device, or if the governmental entity finds that our

31

products would cause serious adverse health consequences. A government mandated or voluntary recall or field action by us could occur as a result of component failures, manufacturing errors or design defects, including labeling defects. Any recall of our products may harm our reputation with customers and divert managerial and financial resources.

We may be subject to fines, penalties or injunctions if we are determined to be promoting the use of our products for unapproved or “off-label” uses.

If we are incorrect in our belief that our promotional materials and training methods regarding physicians are conducted in compliance with regulations of the FDA and other applicable regulations, and the FDA determines that our promotional materials or training constitutes promotion of an unapproved use, the FDA could request that we modify our training or promotional materials or subject us to regulatory enforcement actions, including the issuance of a warning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement.

We are subject to healthcare fraud and abuse regulations that could result in significant liability, require us to change our business practices and restrict our operations in the future.

We are subject to various federal, state and local laws targeting fraud and abuse in the healthcare industry, including anti-kickback and false claims laws. Violations of these laws are punishable by criminal or civil sanctions, including substantial fines, imprisonment and exclusion from participation in healthcare programs such as Medicare and Medicaid and health programs outside the United States. These laws and regulations are wide ranging and subject to changing interpretation and application, which could restrict our sales or marketing practices. Furthermore, since many of our customers rely on reimbursement from Medicare, Medicaid and other governmental programs to cover a substantial portion of their expenditures, our exclusion from such programs as a result of a violation of these laws could have a material adverse effect on our business, results of operations, financial condition and cash flow.

Failure to attract additional capital which we may require to expand our business could curtail our growth.

We may require additional capital to expand our business. If cash generated internally is insufficient to fund capital requirements, we will require additional debt or equity financing. In addition, we may require financing to fund any significant acquisitions we may seek to make. Needed financing may not be available or, if available, may not be available on terms satisfactory to us and may result in significant stockholder dilution. Covenants in our industrial bond financing may also restrict our ability to obtain additional debt financing. If we fail to obtain sufficient additional capital in the future, we could be forced to curtail our growth strategy by reducing or delaying capital expenditures and acquisitions, selling assets, restructuring our operations or refinancing our indebtedness.

Any disaster at our manufacturing facilities could disrupt our ability to manufacture our products for a substantial amount of time, which could cause our revenues to decrease.

We conduct our manufacturing and assembly at facilities in Queensbury, New York, Manchester, Georgia, Cambridge, England and Fremont, California. It would be difficult, expensive and time-consuming to transfer resources from one facility to the other, replace, or repair these facilities and our manufacturing equipment if they were significantly affected by a disaster. Additionally, we might be forced to rely on third-party manufacturers or to delay production of our products. Insurance for damage to our properties and the disruption of our business from disasters may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all. In addition, if one of our principal suppliers were to experience a

32

similar disaster, uninsured loss or under-insured loss, we might not be able to obtain adequate alternative sources of supplies or products or could face significant delays and incur substantial expense in doing so. Any significant uninsured loss, prolonged or repeated disruption, or inability to operate experienced by us or any of our principal suppliers could cause significant harm to our business, financial condition and results of operations.

Our inability to manage our growth or successfully implement our internal reorganization may have an adverse effect on our business, financial condition or results of operations.

Over the past several years we have experienced significant growth. Our inability to manage our growth or our internal reorganization into strategic business units could impact our ability to meet our customers’ demands, which could cause future sales to suffer.

Our stock price may be volatile, which may cause the value of our stock to decline or subject us to a securities class action litigation.

The trading price of our common stock is likely to be highly volatile and could be subject to wide fluctuations in price in response to various factors, many of which are beyond our control, including:

• general economic, industry and market conditions;

• actions by institutional or other large stockholders;

• the depth and liquidity of the market for our common stock;

• volume and timing of orders for our products;

• developments generally affecting medical device companies;

• the announcement of new products or product enhancements by us or our competitors;

• changes in earnings estimates or recommendations by securities analysts;

• investor perceptions of us and our business, including changes in market valuations of medical device companies;

• our results of operations and financial performance.

In addition, the stock market in general, and the NASDAQ Stock Market and the market for medical devices in particular, have experienced substantial price and volume volatility that is often seemingly unrelated to the operating performance of particular companies. These broad market fluctuations may cause the trading price of our common stock to decline. In the past, securities class action litigation has often been brought against a company after a period of volatility in the market price of its common stock. We may become involved in this type of litigation in the future. Any securities litigation claims brought against us could result in substantial expense and the diversion of management’s attention from our business.

Anti-takeover provisions in our organizational documents and Delaware law may discourage or prevent a change of control, even if an acquisition would be beneficial to our stockholders, which could cause our stock price to decline and prevent attempts by our stockholders to replace or remove our current management.

Our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that may enable our management to resist a change in control. These provisions may 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. Such provisions include:

• our board of directors is authorized, without prior stockholder approval, to create and issue “blank check” preferred stock, with rights senior to those of common stock;

33

• our board of directors is classified so that not all members of our board of directors are elected at one time, which may make it more difficult for a person who acquires control of a majority of our outstanding voting stock to replace our directors;

• advance notice requirements for stockholders to nominate individuals to serve on our board of directors or for stockholders to submit proposals that can be acted upon at stockholder meetings;

• stockholder action by written consent is prohibited;

• stockholders are not permitted to accumulate their votes for the election of directors;

We are also subject to the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. In addition, our board of directors has adopted a stockholder rights plan, which could delay or prevent a change in control of us even if the change in control is generally beneficial to our stockholders. These and other provisions in our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law could make it more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by our then-current board of directors, including delaying or impeding a merger, tender offer or proxy contest involving our company. Any delay or prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.

Item 2. Properties

We own a manufacturing, administrative, engineering and warehouse facility of approximately 104,000 square feet situated on 18 acres in Queensbury, New York. In fiscal 2003, we financed an expansion of this facility with the proceeds of industrial revenue bonds, and the land and buildings are subject to a first mortgage in favor of a bank. In 2006, we issued taxable adjustable rate notes to finance an expansion of 36,000 square feet to our warehouse and manufacturing facility. See Item 7 of this annual report, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources,” for a discussion of these financings. In July 2009, we entered into an agreement to lease a 52,500 square foot office building in Latham, New York that will house our corporate headquarters and certain business operations. The building will be constructed by a commercial real estate developer with a targeted occupancy date of March 2010. See Item 7 of this annual report, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources,” for a discussion of this lease.

We also lease three additional properties. We lease a manufacturing facility of approximately 60,000 square feet located in Manchester, Georgia. This facility also includes office space and is leased through April 2010. We lease 14,500 square feet of office and research and development space in Fremont, California. The lease expires in April 2010. We lease 7,000 square feet of manufacturing facility we acquired in connection with the Flowmedica acquisition, which is also located in Fremont, California. The lease expires in February 2010. Finally, we lease an office and manufacturing facility of approximately 20,000 square feet in the United Kingdom that we acquired in June 2008 in connection with our acquisition of certain assets of Diomed, Ltd. The lease expires in October 2013.

Item 3. Legal Proceedings

AngioDynamics v. Vascular Solutions

On July 29, 2009, AngioDynamics filed a complaint in the United States District Court for the District of Delaware against Vascular Solutions, Inc. (NASDAQ: VASC). The complaint alleges that Vascular Solutions’

34

Vari-Lase Bright-Tip fiber product line infringes on claims of two AngioDynamics patents, US 7,273,478 and US 7,559,329. These patents relate to methods of treating varicose veins using endovenous laser treatments.

Diomed v. AngioDynamics and AngioDynamics v. biolitec

On January 6, 2004, Diomed filed an action against us entitled Diomed, Inc. v. AngioDynamics, Inc., et al., civil action no. 04 10019 RGS in the U.S. District Court for the District of Massachusetts. Diomed’s complaint alleged that we infringed on Diomed’s U.S. patent no. 6,398,777 by selling a kit for the treatment of varicose veins (now called the “VenaCure Procedure Kit”) and two diode laser systems (the Precision 980 Laser and the Precision 810 Laser), and by conducting a training program for physicians in the use of the VenaCure Procedure Kit. The complaint alleged that our actions have caused Diomed to suffer substantial damages.

On March 28, 2007, the jury in the proceeding returned a verdict in favor of Diomed and awarded compensatory monetary damages in the amount of $8.36 million. The jury concluded, however, that there was no willful infringement by us. On May 22, 2007, the judge for the Federal District Court in Boston denied our motion to overturn the verdict and increased the judgment for compensatory damages by $1.35 million, to $9.71 million, to cover pretrial interest and post-verdict sales of the infringing products. We disputed the infringement verdict on multiple grounds and on June 20, 2007, filed an appeal in the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. The judgment also required us to pay interest to Diomed at an annual rate of approximately 5% of the damage award for the period of time between the verdict and actual payment of the award. As a result we accrued approximately $10.2 million, including interest. On July 2, 2007, the judge for the Federal District in Boston, Massachusetts, issued an injunction prohibiting us from selling our original bare fiber VenaCure product.

On March 14, 2008, Diomed commenced Chapter 11 bankruptcy proceedings. On April 2, 2008, we entered into a settlement with Diomed for the purpose of resolving the alleged patent infringement and paid $7.0 million in the fourth quarter of 2008. As a result of the settlement, in our third quarter of fiscal 2008 we reduced our litigation provision and recorded a gain of approximately $3.2 million pretax.

Until April 2007, we purchased the lasers and laser fibers for our laser systems from biolitec under a supply agreement. In 2006, biolitec advised us that based on Diomed’s refinement of its claims in the Diomed action, biolitec believed such claims were not within biolitec’s indemnification obligations under the supply agreement. We advised biolitec that we disagreed with biolitec’s position and that we expected biolitec to continue to honor its indemnification obligations.

On January 2, 2008, we commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v. biolitec, Inc. in which we are seeking, in part, judgment against biolitec for indemnification of defense costs we incurred in the Diomed action and the VNUS action described below. Biolitec has filed counter-claims against us seeking reimbursement of approximately $1.6 million in alleged past defense costs paid by biolitec in one of the settled cases.

We will continue to vigorously enforce our rights under the supply agreement with biolitec. However, in the event it is ultimately determined that the claims asserted in the Diomed action and the VNUS action are not within biolitec’s indemnification obligations under the biolitec supply agreement, we may be required to reimburse biolitec for the costs and expenses of defending the Diomed action.

VNUS Medical Technologies v. Diomed, Vascular Solutions, and AngioDynamics

On October 4, 2005, VNUS Medical Technologies, Inc. (“VNUS”) filed an action against us and others (collectively, the “Defendants”) entitled VNUS Medical Technologies, Inc. v. Diomed Holdings, Inc., Diomed Inc., AngioDynamics, Inc., and Vascular Solutions, Inc. , case no. C05-2972 MMC, filed in the U.S. District Court for the Northern District of California. The complaint alleged that the Defendants infringed on VNUS’s

35

U.S. patent nos. 6,258,084, 6,638,273, 6,752,803, and 6,769,433 by making, using, selling, offering to sell and/or instructing users how to use Diomed’s “EVLT” products, AngioDynamics’ “VenaCure” products, and Vascular Solutions’ “Vari-Lase” products. The complaint alleged the Defendants’ actions caused VNUS to suffer substantial damage. The complaint sought to prohibit the Defendants from continuing to market and sell these products and asks for compensatory and treble money damages, reasonable attorney fees, costs and pre-judgment and post-judgment interest.

On June 3, 2008, we entered into an agreement with VNUS settling all patent litigation between us and VNUS. Under the terms of the settlement agreement, we paid VNUS approximately $6.8 million pretax. Accordingly, we recorded an accrual of $6.8 million as of May 31, 2008 which is included under the heading “Litigation provision” on the consolidated balance sheet. This payment was made in fiscal 2009. In addition, we agreed to pay a quarterly royalty on our U.S. sales of our NeverTouch(TM), VenaCure(R) and Diomed products from June 1, 2008 until the expiration date of VNUS’applicable patents. In exchange, VNUS granted us a non-exclusive and non-sublicenseable license to VNUS’ applicable patents for use in endovenous laser therapy.

We are party to other legal actions that arise in the ordinary course of business. We believe that any liability resulting from any currently pending litigation will not, individually or in the aggregate, have a material adverse effect on our business or financial condition, results of operations or cash flow.

Overview

We are a provider of innovative medical devices used in minimally invasive, image-guided procedures to treat peripheral vascular disease, or PVD, and local oncology therapy options for treating cancer, including radiofrequency ablation (“RF” or “RFA”) systems, irreversible electroporation (“IRE”) surgical resection systems and embolization products for treating benign and malignant tumors. We design, develop, manufacture and market a broad line of therapeutic and diagnostic devices that enable interventional physicians (interventional radiologists, vascular surgeons, interventional and surgical oncologists and others) to treat PVD, tumors, and other non-coronary diseases.

Historically, we reported our results of operations as a single segment. Beginning with fiscal 2009, we have organized our business into three reportable segments: Peripheral Vascular, Access and Oncology/Surgery. The Peripheral Vascular segment is comprised of the venous, angiographic, PTA, drainage and thrombolytic product lines. The Access segment is comprised of the dialysis, port and PICC product lines. The Oncology/Surgery segment is comprised of the RFA, embolization, Habib and NanoKnife product lines. Prior periods have been recast for net sales and gross profit for this new reporting structure.

For the past five fiscal years, over 95% of our net sales were from single-use, disposable products. The following table sets forth our aggregate net sales from the following product categories for our last three fiscal years:

	2009				2008				2007
	Net Sales		% of Net Sales		Net Sales		% of Net Sales		Net Sales		% of Net Sales
	(dollars in thousands)
Peripheral Vascular	$	83,457	42.8	%	$	63,675	38.2	%	$	58,132	51.8	%
Access		66,812	34.3	%		64,434	38.7	%		42,922	38.2	%
Oncology/Surgery		44,785	23.0	%		38,391	23.1	%		11,173	10.0	%
Total	$	195,054	100.0	%	$	166,500	100.0	%	$	112,227	100.0	%

We sell our broad line of quality devices in the United States through a direct sales force and outside the U.S. through a combination of direct sales and distributor relationships. As of May 31, 2009, our sales organization numbered 139 in the U.S. and 15 outside the U.S. For fiscal years 2009, 2008 and 2007, net sales in non-U.S markets were 11.1%, 9.5%, and 6.3% respectively. The increase in our net sales outside the U.S. is primarily as a result of the Diomed acquisition completed in June 2008 and the RITA acquisition completed in January 2007.

Our growth depends in large part on the continuous introduction of new and innovative products, together with ongoing enhancements to our existing products, through internal product development, technology licensing and strategic alliances. We recognize the importance of, and intend to continue to make investments in, research and development. For fiscal 2009, 2008 and 2007, our research and development (“R&D”) expenditures were $17.9 million, $14.4 million, and $20.6 million, respectively, and constituted 9.2%, 8.7%, and 18.3%,

43

respectively, of net sales. A significant portion of our R&D expenses in 2007 related to a $12.1 million charge for in-process R&D from our acquisition of RITA. Excluding this charge, our R&D expenses were approximately 7.5% of net sales in 2007. R&D activities include research, product development, intellectual property affairs and regulatory affairs. R&D expenditures for IRE projects totaled $6.9 million in 2009, or 4% of net sales. We expect that our R&D expenditures will be approximately 10% of net sales in fiscal 2010 primarily due to investment in IRE technology and remain in the range of 8 to 10% of net sales thereafter. However, downturns in our business could cause us to reduce our R&D spending.

We are also seeking to grow through selective acquisitions of complementary businesses and technologies. In January 2007, we acquired RITA Medical Systems, Inc. This acquisition created a diversified medical technology company with a broad line of access, diagnostic and therapeutic products that enable interventional physicians and surgeons to treat peripheral vascular disease and cancerous tumors. Interventional oncology is a large and growing area for our existing customer base and RITA’s leadership position, premium products and excellent reputation fit our strategy. RITA had a very strong position in vascular access ports, which are an ideal sales fit with our Morpheus^® CT PICC. In addition, in May 2008 we acquired irreversible electroporation (IRE) technology which will be complementary to RITA’s diverse offering of local oncology therapies, including its market-leading RFA systems, Habib Sealer^TM resection devices and LC Beads ^TM for tumor embolization. We are in the process of commercializing the IRE technology and recently introduced the NanoKnife generator. In June 2008, we completed the acquisition of certain U.S. and U.K. assets of Diomed, Inc. With this acquisition, we substantially strengthened our position in the market for the treatment of varicose veins. The combination of Diomed endovenous laser products with our existing venous product line provides us with a comprehensive venous product offering. In January 2009, we completed the acquisition of certain assets of FlowMedica, Inc. providing us with the Benephit product line, a therapeutic approach to deliver drugs directly to the kidneys in order to prevent and treat acute kidney injury, in the emerging field of Targeted Renal Therapy.

Except to the extent we can further use our equity securities as acquisition capital, we will require additional equity or debt financing to fund any future significant acquisitions.

For fiscal 2009, approximately 35% of our product sales were derived from products manufactured for us by third parties, compared to 27% for fiscal 2008. We intend to manufacture more products in-house to lower product costs and increase profitability. In 2002 and 2006, we expanded our manufacturing facility in Queensbury, New York, to provide us with additional manufacturing capacity and to accommodate additional research, development and administrative requirements. In July 2009, we entered into an agreement to lease a 52,500 square foot office building in Latham, New York that will house our corporate headquarters and certain business operations. The building will be constructed by a commercial real estate developer with a targeted occupancy date of March 2010.

Our ability to increase our profitability will depend in large part on improving gross profit margins. Factors such as changes in our product mix, new technologies and unforeseen price pressures may cause our margins to grow at a slower rate than we have anticipated or to decline.

Recent Developments

CEO Transition

On January 20, 2009, we entered into an Employment Agreement and Non-Statutory Stock Option Agreement with our then chief executive officer that provided, among other things, for a transition to a new chief executive officer. The transition to the new chief executive was completed in the third quarter of fiscal 2009. The former chief executive officer did not have an operating role after February 28, 2009. Accordingly, we recorded a provision in fiscal 2009 of approximately $2.9 million in general and administrative expenses for all current and future costs associated with the aforementioned Employment Agreement and Non-Statutory Stock Option Agreement and certain costs associated with the recruitment of a new chief executive officer. The new CEO commenced employment with us in March 2009.

Acquisition of FlowMedica, Inc.

On January 12, 2009, we completed the acquisition of certain assets of FlowMedica, Inc. for approximately $1.75 million in cash and a contingent payment based on fiscal 2011 sales of FlowMedica products. With this acquisition, we purchased the Benephit product line, a therapeutic approach to deliver drugs directly to the kidneys in order to prevent and treat acute kidney injury, in the emerging field of Targeted Renal Therapy. Intangible assets acquired totaled approximately $1.3 million which have been identified as product technologies (10-year weighted average useful life). Inventory acquired totaled approximately $400,000. The acquisition is being accounted for as a purchase and, accordingly, we have included the results of operations in the financial statements effective January 12, 2009, the date of acquisition. The pro-forma effects of the acquisition were not material to our income statement and balance sheet. Ten employees of FlowMedica, Inc. became employees upon completion of the acquisition.

Acquisition of certain assets of Diomed

On June 17, 2008, we completed the acquisition of certain U.S. assets of Diomed, Inc. and UK assets of Diomed UK Limited., in separate transactions, for an aggregate purchase price of approximately $11.1 million in cash including capitalized acquisition costs. With this acquisition, we substantially strengthened our position in the market for the treatment of varicose veins. The combination of Diomed endovenous laser products with our existing venous product line provides us with a comprehensive venous product offering. The total of the net tangible assets acquired was $5.5 million. Goodwill recorded as a result of these acquisitions was approximately $1.9 million. Intangible assets acquired, other than goodwill, totaled approximately $3.7 million of which $3.6 million has been identified as customer relationships (8-year estimated weighted average useful life ) and $100,000 has been identified as product technologies (10-year estimated weighted average useful life).

The acquisition is being accounted for as a purchase and, accordingly, we have included the results of operations in the financial statements effective June 17, 2008, the date of acquisition. The pro-forma effects of the Diomed acquisition on our income statement and balance sheet were not material. Thirty five employees of Diomed became employees of ours upon completion of the acquisition.

Acquisition of Oncobionic, Inc.

On May 9, 2008, we completed the acquisition of all the issued and outstanding shares of capital stock of Oncobionic, Inc. pursuant to the terms of the Stock Purchase Agreement entered into on October 12, 2006. The closing of the acquisition came as a result of the successful use of irreversible electroporation (IRE) technology in the first human clinical trial for the treatment of soft tissue, conducted during the first week of April 2008.

Under the October 2006 Stock Purchase Agreement, we agreed to pay a total purchase price of $25.4 million, including $400,000 of assumed liabilities. We made payments of $5.0 million upon the execution of the stock purchase agreement in October 2006, $10.0 million on May 9, 2008 upon the closing of the acquisition, and $5.0 million in November 2008. The remaining $5.0 million is payable in November 2009.

The Stock Purchase Agreement also provides for future royalty payments due on net sales of any catheter-based products sold by us that incorporate irreversible electroporation technology (“IRE”). We hold a license to such technology under a license agreement with the Regents of the University of California (the “UC License”).

Acquisition of RITA Medical Systems, Inc.

On January 29, 2007, we completed the acquisition of RITA for a total purchase price of approximately $244 million, comprised of approximately $24 million in cash, 7.9 million shares of common stock, and assumption of outstanding RITA options and other convertible securities, which were exercisable for an additional 1.9 million shares of our common stock at the time of acquisition.

45

RITA’s operating results were consolidated with those of AngioDynamics beginning on the date of the acquisition, January 29, 2007. Since our results are not restated retroactively to reflect the historical financial position or results of RITA, fluctuations in our operating results for 2007 as compared to the 2008 and 2009 period are significantly impacted by the acquisition of RITA.

We acquired RITA for its market position, premium product offerings, developed and emerging technologies in the fields of interventional oncology and vascular access and its highly skilled workforce. The merger was pursued and completed because the management groups and stockholders of AngioDynamics and RITA believed the combined entity would achieve higher sales and profitability than either or both of the pre-merger companies on a standalone basis.

Company Reorganization

Historically, we reported our results of operations as a single segment. Beginning with fiscal 2009, we have organized our business into three reportable segments: Peripheral Vascular, Access and Oncology/Surgery. The Peripheral Vascular segment is comprised of the venous, angiographic, PTA, drainage and thrombolytic product lines. The Access segment is comprised of the dialysis, port and PICC product lines. The Oncology/Surgery segment is comprised of the RFA, embolization, Habib and NanoKnife product lines. Prior periods have been recast for net sales and gross profit for this new reporting structure.

Critical Accounting Policies and Use of Estimates

Our significant accounting policies are summarized in Note A to our consolidated financial statements included elsewhere in this annual report on Form 10-K. While all these significant accounting policies affect the reporting of our financial condition and results of operations, we view certain of these policies as critical. Policies determined to be critical are those policies that have the most significant impact on our financial statements and require us to use a greater degree of judgment and/or estimates. Actual results may differ from those estimates. The accounting policies identified as critical are as follows:

Revenue Recognition

We recognize revenue in accordance with generally accepted accounting principles as outlined in the SEC’s Staff Accounting Bulletin No. 104, “Revenue Recognition,” which requires that four basic criteria be met before revenue can be recognized: (i) persuasive evidence that an arrangement exists; (ii) the price is fixed or determinable; (iii) collectibility is reasonably assured; and (iv) product delivery has occurred or services have been rendered. Decisions relative to criterion (iii) regarding collectibility are based upon our judgments, as discussed under “Accounts Receivable” below, and should conditions change in the future and cause us to determine this criterion is not met, our results of operations may be affected. We recognize revenue, net of sales taxes assessed by any governmental authority, as products are shipped, based on F.O.B. shipping point terms when title and risk of loss passes to customers. We negotiate shipping and credit terms on a customer-by-customer basis and products are shipped at an agreed upon price. All product returns must be pre-approved by us and customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least 12 months remaining prior to its expiration date.

Accounts Receivable

Accounts receivable, principally trade, are generally due within 30 to 90 days and are stated at amounts due from customers, net of an allowance for doubtful accounts. We perform ongoing credit evaluations of our customers and adjust credit limits based upon payment history and the customer’s current credit worthiness, as determined by a review of their current credit information. We continuously monitor aging reports, collections and payments from customers, and maintain a provision for estimated credit losses based upon our historical experience and any specific customer collection issues that we identify. While such credit losses have historically

46

been within our expectations and the provisions established, we cannot guarantee that the same credit loss rates will be experienced in the future. We write off accounts receivable when they are determined to be uncollectible. For fiscal years 2009, 2008, and 2007, our write offs of accounts receivable have been insignificant.

Income Taxes

In preparing our financial statements, we calculate income tax expense for each jurisdiction in which we operate. This involves estimating actual current taxes due plus assessing temporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities. We periodically evaluate deferred tax assets, capital loss carryforwards and tax credit carryforwards to determine their recoverability based primarily on our ability to generate future taxable income and capital gains. Where their recovery is not likely, we estimate a valuation allowance and record a corresponding additional tax expense in our statement of operations. If actual results differ from our estimates due to changes in assumptions, the provision for income taxes could be materially affected. As of May 31, 2009, our valuation allowance and net deferred tax asset were approximately $1.2 million and $13.6 million, respectively. The deferred tax asset includes $80.8 million of Federal net operating loss carryforwards and $27.4 million of state net operating loss carryforwards remaining from the RITA acquisition. These losses could be significantly limited under Internal Revenue Code (“IRC”) Section 382. Our analysis of RITA’s ownership changes as defined in IRC Section 382 shows that approximately $15.0 million of remaining Federal net operating losses and $11.8 million of remaining state net operating losses will expire prior to utilization. The gross deferred tax asset related to the net operating losses reflects this limitation.

We need to generate approximately $4 million of taxable income in each year over the next seventeen years to ensure the realizability of our deferred tax assets. We have determined that we have sufficient existing levels of pre-tax earnings to generate sufficient taxable income to realize the net deferred tax assets recorded on our balance sheet.

In order to support the realizability of our net deferred tax asset, we projected our pre-tax income utilizing a combination of historical and projected results. Utilizing this projected pre-tax income, we have projected taxable income taking into consideration existing levels of permanent differences including stock option exercise deductions and non-deductible expenses and the reversal of significant temporary differences.

Our Federal net operating loss carryforwards as of May 31, 2009 after considering IRC Section 382 limitations are $65.0 million. The expiration of the Federal net operating loss carryforwards are as follows: $0.6 million between 2010 and 2011, $29.8 million between 2017 and 2021 and $34.6 million between 2022 and 2026.

Our state net operating loss carryforwards as of May 31, 2009 after considering remaining IRC Section 382 limitations are $15.6 million which expire in various years from 2010 to 2026.

In November 2005, the FASB issued FASB Staff Position SFAS No. 123(R)-3, “Transition Election to Accounting for the Tax Effect of Share-Based Payment Awards”. We have elected to adopt the modified prospective transition method for calculating the tax effects of stock-based compensation pursuant to SFAS No. 123(R). Under the modified prospective transition method, no adjustment is made to the deferred tax balances associated with stock-based payments that continue to be classified as equity awards. Additionally, we elected to use the “long-form method,” as provided in paragraph 81 of SFAS No. 123(R) to determine the pool of windfall tax benefits. The long-form method requires us to analyze the book and tax compensation for each award separately as if it had been issued following the recognition provisions of SFAS No. 123, subject to adjustments for net operating loss carryforwards.

In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109” (FIN 48), which

47

clarifies the accounting for uncertainty in tax positions. FIN 48 seeks to reduce the diversity in practice associated with certain aspects of the recognition and measurement related to accounting for income taxes. This Interpretation requires us to recognize in our financial statements the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. This Interpretation is effective for fiscal years beginning after December 15, 2006, with the cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. We adopted this statement on June 3, 2007. There was no cumulative effect of adopting FIN 48. Upon adoption, the liability for unrecognized tax benefits was zero.

During the twelve months ended May 31, 2009, we did not recognize any tax liabilities related to uncertain tax positions.

We recognize interest and penalties related to unrecognized tax benefits within our global operations as a component of income tax expense. This accounting policy did not change as a result of the adoption of FIN 48. Accrued interest and penalties recognized in the consolidated balance sheet were $0 as of May 31, 2009 and May 31, 2008.

We file income tax returns in the U.S. Federal jurisdiction and various state and foreign jurisdictions. In the normal course of business we are subject to examination by taxing authorities throughout the world. The Internal Revenue Service (“IRS”) completed an examination of our Federal income tax returns for fiscal years 2006 and 2007 in February 2009 which did not result in a material impact on our results of operations or financial position. Fiscal years 2006 through 2009 remain open to examination by the various tax authorities. We analyzed filing positions in all of the Federal and state jurisdictions where we are required to file income taxes, as well as all open tax years in these jurisdictions and believe that our income tax filing positions and deductions will be sustained on audit and we do not anticipate any adjustments will result in a material adverse effect on our financial condition, results of operations or cash flow.

Management does not anticipate that the amount of unrecognized tax benefits will significantly change in the next twelve months.

Inventories

Inventories are stated at the lower of cost (at standard cost which approximates the first-in, first-out method) or market. On a quarterly basis, we review inventory quantities on hand and analyze the provision for excess and obsolete inventory based primarily on product expiration dating and our estimated sales forecast, which is based on sales history and anticipated future demand. Our estimates of future product demand may not be accurate and we may understate or overstate the provision required for excess and obsolete inventory. Accordingly, any significant unanticipated changes in demand could have a significant impact on the value of our inventory and results of operations. As of May 31, 2009, May 31, 2008, and June 2, 2007, our reserve for excess and obsolete inventory was $3,074,000, $3,694,000, and $2,760,000, respectively.

Property, Plant and Equipment

We state property, plant and equipment at cost, less accumulated depreciation, and depreciate these assets using the straight-line method over their estimated useful lives. We determine this based on our estimates of the period over which the assets will generate revenue. We evaluate these assets for impairment annually or as changes in circumstances or the occurrence of events suggest the remaining value is not recoverable. Any change in condition that would cause us to change our estimate of the useful lives of a group or class of assets may significantly affect depreciation expense on a prospective basis.

48

Goodwill and Intangible Assets

Intangible assets other than goodwill are amortized over their estimated useful lives, which range between three and nineteen years, on either a straight-line basis over the expected period of benefit or as revenues are earned from the sales of the related products. We periodically review the estimated useful lives of our intangible assets and review such assets for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Our determination of impairment is based on estimates of future cash flows. If an intangible asset is considered to be impaired, the amount of the impairment will equal the excess of the carrying value over the fair value of the asset.

For goodwill, the evaluation requires a comparison of the estimated fair value of the reporting unit to which the goodwill is assigned to the sum of the carrying value of the assets and liabilities of that unit. If the sum of the carrying value of the assets and liabilities of a reporting unit exceeds the fair value of the reporting unit, the carrying value of the reporting unit’s goodwill is reduced to its implied fair value through an adjustment to the goodwill balance, resulting in an impairment charge. Our determination of impairment is based on estimates of future cash flows. We will test goodwill for impairment during the third quarter of every fiscal year, and when an event occurs or circumstances change such that it is reasonably possible that impairment exists. Events that could, in the future, result in impairment include, but are not limited to, sharply declining sales for a significant product or in a significant geographic region.

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination. Beginning in fiscal 2009 we began reporting three operating segments. The reporting units are consistent with our operating segments, and include Peripheral Vascular, Access and Oncology/Surgery. As a result, the carrying value of goodwill was allocated to each of the reporting units on a relative fair value basis. We completed our annual evaluation of goodwill by reporting unit as of December 31, 2008. Our assessment of goodwill impairment indicated that the fair value of each of the reporting units exceeded its carrying value and therefore goodwill in each of the reporting units was not impaired. The fair value of Peripheral Vascular, Access and Oncology/Surgery exceeded its carrying value by 29%, 5% and 3%, respectively. The sum of the fair values of the reporting units was reconciled to our current market capitalization (based upon our stock price) plus an estimated control premium of approximately 19% as of December 31, 2008.

To determine fair value, we utilized two market-based approaches and an income approach. Under the market-based approaches, we utilized information regarding our company as well as publicly available industry information to determine earnings multiples and sales multiples. Under the income approach, we determined fair value based on estimated future cash flows of each reporting unit, discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. We determined the discounted cash flow as the best indicator to determine fair value.

Determining the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growth rates, operating margins, discount rates and future market conditions, among others. Solely for purposes of establishing inputs for the fair value calculations, we assumed that the current economic conditions would continue through fiscal year 2010, followed by a recovery period in fiscal years 2011 and 2012. In addition, we applied gross margin assumptions consistent with our company’s historical trends at various revenue levels and used a EBITDA exit multiple of 6.5, 7.0 and 8.0 to calculate the terminal value of the Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively, compared to an EBITDA exit multiple of 8.0 used in the prior year. In addition, we used a discount rate of 19%, 16% and 19% to calculate the fair value of the Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively. This discount rate is higher than the 14% discount rate used in the prior year, primarily due to the fact that additional risk premiums were added to take into account the economic downturn and specific inherent risks associated with each reporting unit.

49

Since early November 2008, our stock market capitalization has generally been lower than our shareholders’ equity or book value. However, our reporting units have continued to generate significant cash flow from their operations, and we expect that they will continue to do so in 2009 and beyond. Furthermore, given the relatively small difference between our stock price and our book value per share, we believe that a reasonable potential buyer would offer a control premium for our business that would adequately cover the difference between our trading prices and our book value.

Even though we determined that there was no goodwill impairment as of December 31, 2008, the future occurrence of a potential indicator of impairment, such as a significant adverse change in legal factors or business climate, an adverse action or assessment by a regulator, unanticipated competition, a material negative change in relationships with significant customers, strategic decisions made in response to economic or competitive conditions, loss of key personnel or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed of, would require an interim assessment for some or all of the reporting units prior to the next required annual assessment as of December 31, 2009. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.

Stock-based compensation

On June 4, 2006, (the “Effective Date”) we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment,” (“SFAS 123(R)”), which requires the measurement and recognition of compensation expense for all share-based payment awards made to our employees and directors including employee stock options and employee stock purchases related to our Stock Purchase Plan based on estimated fair values. We adopted SFAS 123(R) using the “modified-prospective method,” which is a method in which compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS 123(R) for all share-based payments granted after the effective date and (b) based on the requirements of Statement No. 123 for all awards granted to employees prior to the effective date of SFAS 123(R) that remain unvested on the effective date. In accordance with this method of adoption, prior period results of operations and financial position have not been restated to reflect the impact of stock-based compensation. Prior to the adoption of SFAS 123(R), we accounted for options using the intrinsic value method under the guidance of APB No. 25, and provided pro forma disclosure as allowed by Statement No. 123.

For 2009, stock based compensation was $5.8 million pre-tax ($3.7 million after tax, or $0.15 per diluted share) and $4.9 million pre-tax ($3.4 million after tax, or $0.14 per diluted share) in 2008.

Under the provisions of SFAS 123(R), we expect to recognize the following future expense for awards granted prior to May 31, 2009:

	Unrecognized Compensation Cost		Weighted- Average Remaining Vesting Period (in years)
Stock options	$	9,314,460	2.46
Non-vested stock awards		1,552,787	2.89
	$	10,867,247	2.52

Unrecognized compensation cost for stock options is presented net of 4.0% assumed annual forfeitures.

We recognize compensation expense for our stock awards issued subsequent to the adoption of SFAS 123(R) on a straight-line basis over the substantive vesting period. Prior to the adoption of SFAS 123(R), we allocated the pro forma compensation expense for stock options over the vesting period using straight-line

50

attribution method. We will continue to amortize compensation expense related to stock options granted prior to the adoption of SFAS 123(R) using a straight-line attribution method.

The amount of stock-based compensation recognized is based on the value of the portion of awards that are ultimately expected to vest. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. We currently expect, based on an analysis of our historical forfeitures, that approximately 96% of our options will vest annually, and we have therefore applied a 4.0% annual forfeiture rate in determining the stock-based compensation charge recorded. We will re-evaluate this estimate periodically and adjust the forfeiture rate on a prospective basis as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that actually vest.

For the fiscal years ended May 31, 2009, May 31, 2008 and June 2, 2007, we used the Black-Scholes option-pricing model (“Black-Scholes”) as our method of valuation under SFAS 123(R) and a single option award approach. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Black-Scholes was also previously used for our pro forma information required by SFAS 123 for periods prior to June 4, 2006. The fair value of share based payment awards on the date of the grant as determined by the Black-Scholes model is affected by our stock price as well as other assumptions. These assumptions include, but are not limited to the expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, and a risk-free interest rate. The risk-free interest rate is based on factual data derived from public sources. The expected stock-price volatility and option life assumptions require significant judgment which makes them critical accounting estimates.

Prior to fiscal 2009, due to our limited public history, we considered historical volatility and trends within our industry/peer group when estimating expected stock price volatility. Beginning with fiscal 2009, we began to utilize our historical volatility when estimating expected stock price volatility. We use yield rates on U.S. Treasury securities for a period approximating the expected term of the award to estimate the risk-free interest rate. The expected term is determined using the simplified method available under SAB 107 due to our limited public history. The dividend yield is based on the history and expectation of dividend payments. We have not paid dividends in the past nor do we expect to pay dividends in the foreseeable future. Our historical data includes information from May 27, 2004, the date of our initial public offering.

On January 20, 2009, we entered into an Employment Agreement and Non-Statutory Stock Option Agreement with our then chief executive officer that provided, among other things, for a transition to a new chief executive officer. The transition to the new chief executive was completed in the third quarter of fiscal 2009 and the former chief executive officer has not had an operating role with the Company since February 28, 2009. Accordingly, we recorded a provision in fiscal 2009 of approximately $2.9 million in our general and administrative expenses for all current and future costs associated with the aforementioned Employment Agreement and Non-Statutory Stock Option Agreement and certain costs associated with the recruitment of our new chief executive officer. At May 31, 2009, approximately $1 million of related CEO transition costs was included in accrued liabilities. The 2009 results also include approximately $600,000 for the write-off of architectural, design and planning costs associated with a project to build an office facility in Queensbury, New York. The project was cancelled upon the decision to lease office space in Latham, New York.

The 2008 results include a $6.8 million provision for the settlement of the VNUS litigation ($4.3 million net of tax), a gain of $3.2 million ($2.0 million net of tax) on the settlement of the Diomed litigation, and post judgment interest expense on the Diomed judgment recorded in fiscal 2007. Our 2007 results include a litigation charge of $9.7 million ($6.1 million, net of tax), for the judgment awarded Diomed and pre-judgment interest, in general and administrative expenses, and $80,000 for post-verdict interest expense.

A significant amount of the expenses we incurred in 2007 related to the acquisition of RITA and were outside the normal course of our operations as a stand-alone company. As required under the rules of purchase accounting, these expenses included an in-process R&D charge of $12.1 million that carries with it no income tax benefit, amortization expense of $1.9 million on the fair value of the acquired intangible assets and $1.2 million

52

of reduced gross margin as a result of the step up in basis and subsequent sale of finished goods inventory we acquired. Additionally, we incurred non-capitalizable integration and restructuring costs of $916,000. These costs aggregated $14.6 million, net of income taxes of $1.5 million.

For 2009, 2008 and 2007, we were able to use net operating losses (“NOLs”) accumulated by RITA to offset the amount of cash we paid for Federal and state income taxes. The cash benefit amounted to approximately $6.7 million, $7.3 million and $2.5 million for the years ended May 31, 2009, May 31, 2008 and June 2, 2007, respectively. According to the rules of purchase accounting, we are unable to use acquired NOLs to offset our provision for income taxes in the statements of operations.

Fiscal years ended May 31, 2009 and May 31, 2008

Net sales. Net sales are derived from the sale of our products and related freight charges, less discounts and returns. Net sales for fiscal 2009 increased by 17%, or $28.6 million, to $195.1 million, from $166.5 million in fiscal 2008. $18.9 million of the $28.6 million was attributable to increased sales of laser ablation products, including those acquired from Diomed. The balance of the growth in net sales was primarily attributable to increased unit sales of LC Bead and the SmartPort CT.

From a business unit perspective, Peripheral Vascular sales increased 31% to $83.5 million from $63.7 million. $18.9 million of the increase was attributable to increased sales of laser ablation products, including those acquired from Diomed. Laser ablation sales increased from $13.2 million in fiscal 2008 to $32.2 million in fiscal 2009, reflecting the acquisition of Diomed and the integration of the VenaCure EVLT product line. Access sales were $66.8 million, an increase of 4%, primarily attributable to increased unit sales of SmartPort CT. Oncology/Surgery sales were $44.8 million, an increase of 17% over the prior year primarily as a result of strong sales of our embolization product, LC Bead.

From a geographical perspective, US sales increased $22.7 million or 15% in fiscal 2009 to $173.4 million from $150.7 million a year ago. Approximately $12.2 million of this increase was attributable to increased sales of laser ablation products, including those acquired from Diomed. The balance of this increase was primarily attributable to increased unit sales of LC Bead and the SmartPort CT. International sales increased $5.9 million or 37% in fiscal 2009 to $21.7 million from $15.8 million a year ago. Approximately $6.8 million of this increase was attributable to the sales of products acquired from Diomed, offset by decreased sales of our Angiographic catheters, PTA products and RF Ablation devices. IRE products (Nanoknife) contributed approximately $194,000 in 2009 in the International Oncology/Surgery business segment sales.

Gross profit. Gross profit consists of net sales less the cost of goods sold, which includes the costs of materials, products purchased from third parties and sold by us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead. Our gross profit as a percentage of sales was 61.6% in fiscal 2009 and fiscal 2008. Our gross profit improved on Peripheral Vascular products reflecting the manufacture of lasers as a result of the Diomed acquisition and declined on Oncology/Surgery products due to increased sales of the lower margin LC Bead product.

Research and development expenses. Research and development (“R&D”) expenses include costs to develop new products, enhance existing products, validate new and enhanced products and register, and maintain and defend our intellectual property. R&D expenses increased by $3.5 million, or 24%, to $17.9 million in fiscal 2009. The increase is primarily due to increased engineering personnel and other costs to support IRE development and commercialization activities. R&D expenditures for the IRE program totaled $6.9 million in fiscal 2009. As a percentage of net sales, R&D expenses were 9.2% for fiscal 2009, compared with 8.7% for the same prior year period. At May 31, 2009, we employed 81 people in research, development, intellectual property and regulatory activities compared with 54 people a year ago.

53

Sales and marketing expenses. Sales and marketing (“S&M”) expenses consist primarily of salaries, commissions, travel and entertainment, attendance at medical society meetings, product promotions and samples. S&M expenses increased $10.7 million or 23% to $56.8 million in fiscal 2009. Sales expenses accounted for $6.6 million of the increase, which represented a 19% increase over the prior year. This is primarily due to personnel expenses and related costs associated with a planned increase in our Peripheral Vascular and Access sales forces with the addition of 19 new sales representatives, personnel hired in the Diomed acquisition and IRE sales activities. Marketing expenses increased approximately $4.1 million, or 40%, over the prior year period, primarily due to IRE marketing activities, increased headcount, costs relating to the Diomed and FlowMedica acquisitions, and additional promotional activities. As a percentage of net sales, S&M expenses were 29.1% for fiscal 2009, compared with 27.7% for the prior year period. $1.0 million was spent on IRE sales and marketing activity in fiscal 2009. At May 31, 2009, we employed 201 people in sales and marketing activities, including 13 hired in the Diomed acquisition, compared with 151 people a year ago.

General and administrative expenses. General and administrative (“G&A”) expenses include executive management, finance and accounting, human resources and information technology and the administrative and professional costs associated with those activities. G&A expenses increased $4.7 million, or 31%, to $20.1 million primarily due to $3.7 million in nonrecurring costs. These nonrecurring costs include transition costs for the CEO position and the write-off of architectural, planning and design costs associated with a cancelled project to build office space in Queensbury, New York. The remaining increase is primarily due to increased headcount for infrastructure growth across the administrative functions and business unit general management costs, which were partially offset by reduced legal expenses from now resolved litigation. G&A expenses were 10.3% of net sales in fiscal 2009, and 9.3% in fiscal 2008. As of May 31, 2009, we employed 56 people in general and administrative activities, including 5 hired in the Diomed acquisition, compared with 40 people a year ago.

Amortization of intangibles. Amortization of intangibles increased $2.3 million to $9.1 million in fiscal 2009, from $6.8 million in the same period of the prior year. The increase is primarily attributable to the amortization of intangibles acquired in the acquisitions of Oncobionic, and Diomed, which was approximately $1.7 million and $500,000, respectively, in fiscal 2009.

Litigation provision, net. The fiscal 2008 results included a $6.8 million provision for the settlement of the VNUS litigation and a gain of $3.2 million related to settlement of the Diomed litigation. For fiscal 2009, no litigation provision was deemed necessary.

Operating income. Operating income was $16.1 million and $16.2 million for fiscal 2009 and 2008, respectively. As a percentage of sales, operating income was 8.3% in fiscal 2009 and 9.8% in fiscal 2008.

Other (expenses) income. Other income (expenses) includes interest income, realized gains and losses from the sales of marketable securities, changes in fair value of an interest rate swap, foreign currency translation gains and losses and interest expense. Other (expenses) were $952,000 for fiscal 2009 compared with other income of $1.1 million in fiscal 2008. The decline was primarily attributable to decreased interest income on reduced cash balances and lower investment yields as a result of market conditions, and increased foreign exchange losses partially offset by lower interest expense as a result of the payment during fiscal 2009 of the Convertible Notes assumed in the acquisition of RITA.

Income taxes. Our provision for income taxes decreased $1.2 million in fiscal 2009, to $5.2 million from $6.4 million in fiscal 2008. Our effective tax rate was 34.5% in fiscal 2009 and 37.2% in fiscal 2008. The R&D tax credit expired on December 31, 2007 and was reinstated on October 3, 2008. The reinstatement retroactively extended R&D tax credits from January 1, 2008 to December 31, 2009. The credit’s retroactive renewal reduced our fiscal 2009 effective tax rate by 1.4%. 2009 federal income tax payments were reduced by $6.7 million through the utilization of net operating losses acquired as a result of the RITA acquisition compared with $7.3 million in 2008.

54

Fiscal years ended May 31, 2008 and June 2, 2007

Net sales. Net sales are derived from the sale of our products and related freight charges, less discounts and returns. For fiscal 2008, net sales increased 48.4%, or $54.3 million, to $166.5 million compared to fiscal 2007. The increase in net sales was primarily attributable to sales of products acquired in the RITA transaction for all of fiscal 2008 compared to fiscal 2007 which only included RITA product sales from the date of the acquisition, January 29, 2007 until the end of the fiscal year. RITA products accounted for $62.8 million or 37.7% of the fiscal 2008 sales as compared with $18.6 million or 16.6% of the fiscal 2007 sales. Our sales growth was driven by recently released products including the new Smart Port CT, Morpheus^© CT PICC Insertion kit, Profiler balloon catheter, the TOTAL Abscession^TM drainage catheter, and Sotradecol^TM. Net sales to non-U.S. markets for fiscal 2008 were $15.9 million, or 9.5% of net sales, compared to $7.1 million, or 6.3% of net sales for fiscal 2007. This increase was primarily due to increased unit sales of vascular access ports and oncology products. Substantially all of the increase in our sales was due to increased unit sales, with less than 1% of the increase attributable to price increases.

Gross profit. Gross profit consists of net sales less the cost of goods sold, which includes the costs of materials, products purchased from third parties and sold by us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead. For fiscal 2008, our gross profit as a percentage of net sales increased to 61.6% from 59.0% for fiscal 2007. The increase in gross margin percentage was primarily due to a favorable product mix resulting from increased sales of higher margin products, including the RITA products and others such as the Morpheus CT PICC, the VenaCure procedure kit, and the TOTAL Abscession^TM drainage catheter, partially offset by increased sales of Sotradecol, which carries a lower gross margin. Gross profit in 2008 also included product efficiencies from the successful integration of RITA which were partially offset by costs associated with the start up of new product production and increases to inventory reserves due to continued focus on product line optimization. Gross profit in 2007 was also reduced by 100 basis points for the amortization of the step up in basis and subsequent sale of finished goods inventory we acquired in the RITA acquisition.

Research and development expenses. Research and development (“R&D”) expenses include costs to develop new products, enhance existing products, validate new and enhanced products and register, and maintain and defend our intellectual property. For fiscal 2008, R&D expenses decreased $6.1 million, or 29.8%, to $14.4 million compared to $20.6 million for fiscal 2007. This decrease is primarily due to the impact of the $12.1 million for in-process R&D related to the RITA acquisition in fiscal 2007. This decrease was offset by expenses associated with the addition of RITA engineering personnel in Fremont, California and Manchester, Georgia along with increased engineering personnel and activities in Queensbury, New York. R&D expenses were 8.7% of net sales for fiscal 2008, compared to 18.3% of net sales for fiscal 2007. Without the in-process R&D charge , 2007 R&D expenses were 7.5% of net sales. At May 31, 2008, we employed 54 people in research, development and regulatory activities compared with 50 people at June 3, 2007, of which 22 were added due to the RITA acquisition in the third quarter of fiscal 2007.

Sales and marketing expenses. Sales and marketing (“S&M”) expenses consist primarily of salaries, commissions, travel and entertainment, attendance at medical society meetings, product promotions and samples. S&M expenses increased $14.4 million or 45.7% to $46.0 million for fiscal 2008. Sales expenses, which accounted for the majority of the increased S&M expenses, increased 57.4%, or $13.1 million This increase is due primarily to the acquisition of RITA and its 44-person sales staff, as well as increased personnel expenses related to the expansion of the number of territories, commissions on higher sales and stock-based compensation. Marketing expenses increased 14.8%, or $1.3 million, also primarily due to the acquisition of RITA and tradeshow expenses. As a percentage of sales, S&M expenses were 27.7% for fiscal 2008, compared with 28.2% for fiscal 2007. At May 31, 2008, we employed 151 people in sales, marketing and customer service activities compared with 140 people at June 2, 2007, of which 62 were added due to the RITA acquisition in the third quarter of fiscal 2007.

55

General and administrative expenses. General and administrative (“G&A”) expenses include executive management, finance and accounting, human resources and information technology and the administrative and professional costs associated with those activities. G&A expenses increased $2.2 million, or 17.1%, to $15.4 million for fiscal 2008 compared to $13.2 million for fiscal 2007. While the expense increased year over year, primarily due to increased stock-based compensation and travel and administrative costs associated with our recent acquisition and integration activities, G&A expenses decreased as a percentage of sales. This decrease, from 11.7% of net sales for fiscal 2007 to 9.3% of net sales for fiscal 2008, is primarily due to synergies achieved in the integration of RITA. We spent approximately $2.0 million in fiscal 2008 in litigation costs associated with the VNUS Medical and Diomed lawsuits. At May 31, 2008, we employed 40 people in general and administrative activities compared with 37 people at June 2, 2007, of which 16 were added due to the RITA acquisition in the third quarter of fiscal 2007.

Litigation provision. The 2008 results include a $6.8 million provision for the settlement of the VNUS litigation and a gain of $3.2 million related to settlement of the Diomed litigation, compared with the prior year period when the Diomed judgment expense of $9.7 million was recorded.

Other income (expenses). Other income (expenses) includes interest income, realized gains and losses from the sales of marketable securities, changes in fair value of an interest rate swap and interest expense. For fiscal 2008, other income (expenses) decreased $3.0 million to $1.1 million, due primarily to increased interest expense incurred on the debt assumed in the RITA acquisition, Diomed provision and the December 2006 bond offering, unrealized losses on the Company’s interest rate swap agreement and decreased interest income on lower invested cash balances combined with decreased market rates. As a percentage of net sales, other income (expenses), net, was 0.7% and 3.6% for fiscal 2008 and 2007, respectively.

Income taxes. Our provision for income taxes increased $4.4 million in fiscal 2008, to $6.4 million from $2.0 million in fiscal 2007. Our effective tax rate for fiscal 2008 is 37.2%. The in-process R&D charge of $12.1 million, which is non-deductible for income tax purposes, had a significant impact on our effective tax rate for fiscal 2007. Without this charge, our effective tax rate for fiscal 2007 was 39.7%. During fiscal year 2008, non deductible items had a smaller impact on our effective tax rate than in the previous year. We also generated more state tax credits during 2008 than in the previous year.

Liquidity and Capital Resources

During the past three years, we have financed our operations primarily through cash flow from operations, the proceeds of our public offerings in 2004 and 2006 and long-term debt. At May 31, 2009, $68.2 million or 16.7% of our assets consisted of cash, cash equivalents and marketable securities. Marketable securities is comprised of U.S. government issued or guaranteed securities, corporate bonds and auction-rate investments. Our current ratio was 5.0 to 1, with net working capital of $118.9 million, at May 31, 2009, compared to a current ratio of 3.4 to 1, with net working capital of $100.5 million, at May 31, 2008. At May 31, 2009, total debt was $7.1 million comprised of short and long-term bank debt for financing our facility expansions in Queensbury, New York compared with total debt at May 31, 2008 which was $17.1 million, comprised of short and long-term bank debt for financing our facility expansions in Queensbury, New York, and $9.7 million of convertible debt acquired in the RITA acquisition, which was paid in cash at maturity during fiscal 2009. Other long-term liabilities at May 31, 2008 consisted of $4.6 million of contractual obligations related to the Oncobionic purchase, net of discount.

We generated cash flow from operations of $19.9 million on net income of $9.9 million for fiscal 2009. Significant non-cash expenses affecting net income included depreciation and amortization of $11.8 million, deferred income tax provision of $4.3 million, and stock-based compensation of $5.8 million. Significant cash used in operating activities included an increase in inventories of $10.5 million and $6.8 million for payment in the Diomed judgment. The increase in inventories is primarily to support the increase in sales activity for all of our products, including those sales related to recently acquired product lines such as Diomed lasers and accessories, and to the timing of contractual purchase commitments for other product inventories.

56

For fiscal 2009, our investing activities used net cash of $15.7 million. We used cash for the acquisition of intangible assets and businesses of $17.1 million, including the Diomed and Flowmedica acquisitions, and $5.0 million contractual payment related to the Oncobionic acquisition. Additionally, we made equipment purchases and building improvements totaling $4.4 million, including the improvements to the facilities in Queensbury, New York and Manchester, Georgia.

Financing activities used net cash of $8.3 million for fiscal 2009. This primarily consists of payment of the $9.7 million in debt acquired in the RITA acquisition offset by proceeds from the issuance of common stock under our employee stock purchase plan of $1.8 million.

In fiscal 2003, we financed an expansion of our headquarters and manufacturing facility with industrial revenue bonds for $3.5 million. To secure this financing, we entered into agreements with local municipalities, a bank, a trustee and a remarketing agent. These agreements are referred to as the IDA agreements. The proceeds of the bonds were advanced as construction occurred. The bonds reprice every seven days and are resold by a Remarketing Agent. The bonds bear interest based on the market rate on the date the bonds are repriced and require quarterly principal payments ranging from $25,000 to $65,000 plus accrued interest through May 2022. We entered into an interest rate swap with a bank to convert the initial variable rate payments to a fixed interest rate of 4.45% per annum. The IDA agreements contain financial covenants relating to fixed charge coverage and interest coverage. The outstanding debt is collateralized by a letter of credit ($2.4 million at May 31, 2009) and a first mortgage on the land, building and equipment representing our facility in Queensbury, New York and we are required to pay an annual fee ranging from 1.0% to 1.9% of the outstanding balance depending on our financial results. The current fee is 1.0% and is in effect until August 22, 2009.

In fiscal 2007, we financed the expansion of our warehouse and manufacturing facility in Queensbury, New York. The expansion was financed principally with taxable adjustable rate notes (the “Notes”) issued by us aggregating $5,000,000. The Notes were issued under a trust agreement by and between us and a bank, as trustee (the “Trustee”). In connection with the issuance of the Notes, we entered into a letter of credit and reimbursement agreement (the “Reimbursement Agreement”) with the Bank that requires the maintenance of a letter of credit to support principal and certain interest payments on the Notes and requires payment of an annual fee on the outstanding balance. The current fee is 0.75% and is in effect until December 2009. We also entered into a remarketing agreement, pursuant to which the remarketing agent is required to use its best efforts to arrange for sales of the Notes in the secondary market. In connection with this financing, we entered into an interest rate swap agreement (the “2006 Swap Agreement”) with the Bank, effective December 2006, with an initial notional amount of $5,000,000, to limit the effect of variability due to interest rates on the rollover of the Notes. The 2006 Swap Agreement is a contract to exchange floating interest rate payments for fixed interest payments periodically over the life of the agreement without the exchange of the underlying notional amounts. The 2006 Swap Agreement requires us to pay a fixed rate of 5.06% and receive payments based on 30-day LIBOR repriced every seven days through December 2016. The Reimbursement Agreement contains certain financial covenants relating to fixed charge coverage and interest coverage, as defined. Amounts borrowed under the Reimbursement Agreement are collateralized by the aforementioned letter of credit and all of our assets. The debt covenants and the collateralization of substantially all of our assets to secure these financings may restrict our ability to obtain debt financing in the future.

In connection with the acquisition of RITA on January 29, 2007, we assumed subordinated Senior Convertible Notes (the “Convertible Notes”) with an aggregate principal amount of $9.7 million. These notes matured and were paid in full during the first quarter of fiscal 2009.

On May 9, 2008, we completed the acquisition of all the issued and outstanding shares of capital stock of Oncobionic, Inc. pursuant to the terms of a stock purchase agreement entered into on October 12, 2006. The closing of the acquisition came as a result of the successful initial use of Oncobionic’s irreversible electroporation (IRE) technology in the first human clinical trial for the treatment of soft tissue, conducted during the first week of April 2008. Under the stock purchase agreement, we agreed to pay a total purchase price of

57

$25.4 million, including $400,000 of assumed liabilities. We made a payment of $5.0 million upon the execution of the stock purchase agreement in October 2006. We paid $10.0 million on May 9, 2008 upon the closing of the acquisition, $5.0 million in November 2008, and the remaining $5.0 million is payable in November 2009.

Our contractual obligations as of May 31, 2009 are set forth in the table below. We have no variable interest entities or other off-balance sheet obligations.

	Cash Payments Due By Period as of May 31, 2009
	Total		Less than One Year		1-3 Years		3-5 Years			After 5 Years

(1) The non-cancelable operating leases and inventory purchase obligations are not reflected on our consolidated balance sheet under accounting principles generally accepted in the United States of America.

(2) Includes Oncobionic and Flowmedica payment obligations.

In July 2009, we entered into an agreement to lease a 52,500 square foot office building in Latham, New York that will house our corporate headquarters and certain business operations. The building will be constructed by a commercial real estate developer with a targeted occupancy date of March 2010. The agreement terms are for an annual rent of $857,321 for the first five years and $943,054 for the next five years. These lease payments are not reflected in the table above. The lease commencement date coincides with the date of occupancy.

We believe that our current cash and investment balances and cash generated from operations will provide sufficient liquidity to meet our anticipated needs for capital for at least the next 12 months. However, if we seek to make significant acquisitions of other businesses or technologies, we may require additional financing. We cannot be assured that such financing will be available on commercially reasonable terms, if at all.

Recent Accounting Pronouncements

In November 2007, the Emerging Issues Task Force (EITF) reached a consensus on EITF Issue No. 07-01, “Accounting for Collaborative Arrangements” (EITF No. 07-01). EITF No. 07-01 establishes disclosure requirements for arrangements entered into by companies to collaboratively develop, manufacture, or market products. EITF No. 07-01 also establishes income statement classification of collaboration transactions between the parties. EITF No. 07-01 is effective for fiscal years beginning after December 15, 2008 (our 2010 fiscal year). We are currently evaluating the impact this adoption will have on our consolidated financial statements.

In December 2007, FASB issued Statement of Financial Accounting Standards No. 141(R), “Business Combinations” (“SFAS 141(R)”). SFAS 141(R) establishes principles and requirements for how the acquirer in a business combination recognizes and measures the assets acquired, liabilities assumed and any noncontrolling interest in the acquiree; recognizes and measures the goodwill acquired or gain from a bargain purchase; and determines what information to disclose to enable readers of the financial statements to evaluate the nature and financial effects of the business combination. SFAS 141(R) is effective for business combinations for which the acquisition date is on or after fiscal years beginning after December 15, 2008 (our 2010 fiscal year) and will be applied prospectively, with the exception of the accounting for valuation allowances on deferred taxes and acquired tax contingencies. FAS 141(R) amends FAS 109 such that adjustments made to valuation allowances on deferred taxes and acquired tax contingencies associated with acquisitions that closed prior to the effective date of FAS 141(R) would also apply the provisions of FAS 141(R).

58

In December 2007, FASB issued Statement of Financial Accounting Standards No. 160, “Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51” (“SFAS 160”). SFAS 160 establishes accounting and reporting standards that require companies to more clearly identify in the financial statements and discloses the impact of noncontrolling interest in a consolidated subsidiary on the consolidated financial statements. SFAS 160 is effective for fiscal years beginning after December 15, 2008 (our 2010 fiscal year), and interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on our financial statements.

In February 2008, the FASB issued FASB Staff Position No. FAS 157-2, “Effective Date of FASB Statement No. 157” (“FSP No. 157-2”), which deferred the effective date of SFAS No. 157 for one year for non-financial assets and liabilities, except for certain items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). We are currently evaluating the impact of SFAS No. 157 on our consolidated financial statements for items within the scope of FSP No. 157-2 which will become effective on June 1, 2009 (our 2010 fiscal year).

In March 2008, FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). SFAS 161 is intended to improve financial reporting about derivative instruments and hedging activities by requiring companies to enhance disclosure about how these instruments and activities affect their financial position, performance and cash flows. SFAS 161 also improves the transparency about the location and amounts of derivative instruments in a company’s financial statements and how they are accounted for under SFAS 133. SFAS 161 is effective for both interim and annual reporting periods beginning after November 15, 2008. We provided the required disclosures in the May 31, 2009 consolidated financial statements.

In June 2008, the FASB issued Staff Position EITF No. 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities” (“EITF No. 03-6-1”). EITF No. 03-6-1 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and therefore need to be included in the earnings allocation in calculating earnings per share under the two class method described in SFAS No. 128, “Earnings per Share.” EITF No. 03-6-1 requires companies to treat unvested share-based payment awards that have non-forfeitable rights to dividend or dividend equivalents as a separate class of securities in calculating earnings per share. It is effective for calendar-year companies beginning January 1, 2009 (our 2010 fiscal year). We are currently assessing the potential impact of implementing this standard.

In June 2008, the FASB ratified Emerging Issues Task Force (“EITF”) Issue No. 07-05, “Determining Whether an Instrument (or Embedded Feature) is Indexed to an Entity’s Own Stock” (“EITF 07-05”). EITF 07-05 mandates a two-step process for evaluating whether an equity-linked financial instrument or embedded feature is indexed to the entity’s own stock. Warrants that a company issues that contain a strike price adjustment feature, upon the adoption of EITF 07-05, results in the instruments no longer being considered indexed to the company’s own stock. Accordingly, adoption of EITF 07-05 will change the current classification (from equity to liability) and the related accounting for such warrants outstanding at that date. EITF 07-05 is effective for fiscal years beginning after December 15, 2008 (our 2010 fiscal year), and interim periods within those fiscal years. We are currently assessing the potential impact of implementing this standard.

In April 2009, the FASB issued FSP SFAS No. 157-4, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions that are Not Orderly” (“FSP SFAS No 157-4”). FSP SFAS No 157-4 provides guidance for estimating fair value in accordance with SFAS No. 157 when the volume and level of activity for the asset or liability have significantly decreased when compared with normal market activity for the asset or liability and for identifying circumstances that indicate a transaction is not orderly. Additionally, FSP SFAS No. 157-4 amends SFAS No. 157 to require disclosure in interim and annual periods of the inputs and valuation techniques used to measure fair value.

59

FAS SFAS No.157-4 is effective for interim and annual periods ending after June 15, 2009 (our 2010 fiscal year) and will be applied prospectively. The adoption of this pronouncement is not expected to have a material impact on our financial statements.

In April 2009, the FASB issued FSP SFAS No. 141(R)-1, “Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies” (“FSP SFAS No. 141(R)-1”). FSP SFAS No. 141 (R)-1 amends and clarifies the initial recognition and measurement, subsequent measurement and accounting and disclosure of assets and liabilities arising from contingencies in a business combination under SFAS No. 141(R). FSP SFAS No 141(R)-1 is effective for acquisitions dates on or after the beginning of the first annual reporting period beginning on or after December 15, 2008 (our 2010 fiscal year).

In April 2009, the FASB issued FSP SFAS No. 107-1 and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments” (“FSP SFAS No 107-1 and APB 28-1”). FSP SFAS No 107-1 and APB 28-1 requires disclosures about fair value of financial instruments for interim period reporting as well as in annual financial statements. Additionally, this FSP requires disclosures regarding the methods and significant assumptions used to estimate the fair value of financial instruments. FSP SFAS No 107-1 and APB 28-1 is effective for interim and annual periods ending after June 15, 2009 (our 2010 fiscal year) but only requires the revised disclosures on a prospective basis. We will provide the additional disclosures necessary to the consolidated financials statements beginning in our first quarter of fiscal year 2010.

In April 2009, the FASB issued FSP SFAS No. 115-2 and SFAS No. 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments” (“FSP SFAS Nos. 115-2 and 124-2”). FSP SFAS Nos. 115-2 and 124-2 amends the other-than-temporary guidance for debt securities and requires additional interim and annual disclosures of other-than-temporary impairments on debt and equity securities. Under FSP SFAS Nos. 115-2 and 124-2, an other-than-temporary impairment of a debt security shall be considered to have occurred if an entity (1) intends to sell the debt security, (2) more likely than not will be required to sell the security before recovery of its amortized cost basis or (3) does not expect to recover the entire amortized cost basis of the security even if it does not intend to sell the security. Once it is determined than an other-than-temporary impairment has occurred, FSP SFAS Nos. 115-2 and 124-2 provides guidance on when to recognize the other-than-temporary impairment in earnings or in other comprehensive income. Depending on which of the above factors(s) caused the impairment to be considered other-than-temporary, (1) the entire shortfall of the security’s fair value versus its amortized cost basis or (2) only the credit loss portion would be recognized in earnings while the remaining shortfall (if any) would be recorded in other comprehensive income. FSP SFAS Nos. 115-2 and 124-2 is effective for interim and annual periods ending after June 15, 2009 (our 2010 fiscal year) and is required to be applied retrospectively to existing investments with a cumulative adjustment to retained earnings and prospectively to new investments purchased after the effective date. We are currently evaluating the impact this adoption will have on our consolidated financial statements.

In May 2009, the FASB issued SFAS No. 165 “Subsequent Events” (“SFAS No. 165”). SFAS No. 165 requires an entity to recognize in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet. For nonrecognized subsequent events that must be disclosed to keep the financial statements from being misleading, an entity will be required to disclose the nature of the event as well as an estimate of its financial effect, or a statement that such an estimate cannot be made. In addition, SFAS No. 165 requires an entity to disclose the date through which subsequent events have been evaluated. SFAS No. 165 is effective for interim and annual periods ending after June 15, 2009 (our 2010 fiscal year) and is required to be applied prospectively. The adoption of this pronouncement is not expected to have a material impact on our financial statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

We are exposed to market risk from changes in interest rates on investments and financing that could impact our results of operations and financial position. Although we have entered into interest rate swaps with a bank to limit our exposure to interest rate change on our variable interest rate financings, we do not currently engage in any other hedging or market risk management tools.

At May 31, 2009, we maintained variable interest rate financing of $7.1 million in connection with our facility expansions. We have limited our exposure to interest rate risk by entering into interest rate swap agreements with a bank under which we agreed to pay the bank fixed annual interest rate of 4.45% and 5.06% and the bank assumed our variable interest payment obligations under the financing.

Nearly all of our sales have historically been denominated in United States dollars. Although not significant, in late fiscal 2007 we began to make sales in other currencies, particularly the Euro, GB pound and Canadian dollar. Approximately 4% of our sales in the fiscal 2009 were denominated in currencies other than the US dollar, primarily the Euro and GB pound. We currently have no significant direct foreign currency exchange risk and such risk in the future is expected to be modest.

Our excess cash is invested in highly liquid, short-term, investment grade securities with maturities primarily of less than two years. These investments are not held for speculative or trading purposes. Changes in interest rates may affect the investment income we earn on cash, cash equivalents and marketable securities and therefore affect our cash flows and results of operations. We hold investments in auction rate securities (“ARS”) in order to generate higher than typical money market investments. ARS typically are high credit quality, generally achieved with municipal bond insurance. Credit risks are eased by the historical track record of bond insurers, which back a majority of this market. Sell orders for any security traded through an auction process could exceed bids. Such instances are usually the result of a drastic deterioration of issuer credit quality. Should there be a failed auction, we may be unable to liquidate our position in the securities in the near term. We have $1.85 million in investments in two auction rate securities issued by New York state and local government authorities that have failed auctions. The authorities are current in their interest payments on the securities.

We are party to legal actions that arise in the ordinary course of business as described in Note Q.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are functioning effectively to provide reasonable assurance that the information required to be disclosed by us (including our consolidated subsidiaries) in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the

61

Securities and Exchange Commission’s rules and forms and is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting in the fiscal year ended May 31, 2009 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for our company. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended, as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States and includes those policies and procedures that:

• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States,

and that our receipts and expenditures are being made only in accordance with authorizations of our management and members of our board of directors; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management has assessed the effectiveness of our internal control over financial reporting as of May 31, 2009. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework.

Based on its assessment and this criteria, subject to the foregoing, management believes that we maintained effective internal control over financial reporting as of May 31, 2009.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

AngioDynamics, Inc. and Subsidiaries:

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of AngioDynamics, Inc. and its Subsidiaries at May 31, 2009 and May 31, 2008, and the results of their operations and their cash flows for each of the three years in the period ended May 31, 2009 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of May 31, 2009, based on criteria established inInternal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Item 9A under Management’s Report on Internal Control over Financial Reporting.

Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note H to the consolidated financial statements, the Company changed the manner in which it accounts for uncertain tax positions effective June 3, 2007.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

May 31, 2009 and May 31, 2008

NOTE A—BASIS OF PRESENTATION, BUSINESS DESCRIPTION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1. Basis of Presentation, Business Description and Recent Events

The consolidated financial statements include the accounts of AngioDynamics, Inc. and its wholly owned subsidiaries, Leocor, Inc. (“Leocor”), RITA Medical Systems, LLC, and Oncobionic, Inc. since May 9, 2008, and AngioDynamics UK Limited since June 17, 2008 (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The Company is primarily engaged in the design, development, manufacture and marketing of medical products used in minimally invasive, image-guided procedures to treat peripheral vascular disease, or PVD, and local oncology therapy options for treating cancer, including radiofrequency ablation, or RFA, systems, irreversible electroporation, or IRE, surgical resection systems and embolization products for treating benign and malignant tumors.

Beginning with fiscal 2009, the Company organized its business into three reportable segments: Peripheral Vascular, Access and Oncology/Surgery. The Peripheral Vascular segment is comprised of the venous, angiographic, PTA, drainage and thrombolytic product lines. The Access segment is comprised of the dialysis, ports and PICC product lines. The Oncology/Surgery segment is comprised of the RFA, embolization, Habib and NanoKnife product lines. The Company’s chief operating decision maker evaluates performance based on the reportable segments and utilizes net sales, gross profit and operating income as primary profitability measures. The expenses related to certain shared and corporate activities are allocated to these segments on a percentage of total sales basis or operating expenses basis as deemed appropriate.

RITA Medical Systems, Inc.

On January 29, 2007, the Company completed the acquisition of RITA Medical Systems, Inc. (“RITA”) for a total purchase price of approximately $244 million, comprised of approximately 7.9 million shares of the Company’s common stock, assumption of outstanding RITA options and other convertible securities and approximately $24 million in cash (See Note C).

Oncobionic, Inc.

On May 9, 2008, the Company completed the acquisition of all the issued and outstanding shares of capital stock of Oncobionic, Inc. (“Oncobionic”) for approximately $25.4 million including $400,000 of assumed liabilities (See Note C).

Diomed, Inc. and Diomed UK Limited.

On June 17, 2008, the Company completed the acquisition of certain U.S. assets of Diomed, Inc. and UK assets of Diomed UK Limited, in separate transactions, for an aggregate purchase price of approximately $11.1 million in cash including capitalized acquisition costs. The total of the net assets acquired was $5.5 million. Goodwill recorded as a result of these acquisitions was approximately $1.9 million. Intangibles assets acquired, other than goodwill, totaled approximately $3.7 million (See Note C).

FlowMedica, Inc.

On January 12, 2009 the Company completed the acquisition of certain assets of FlowMedica, Inc. for approximately $1.75 million in cash and a contingent payment based on fiscal 2011 sales of FlowMedica

products. Intangible assets acquired totaled approximately $1.3 million and inventory acquired totaled approximately $400,000. The Company has included the results of operations in the financial statements effective January 12, 2009 (See Note C).

2. Fiscal Year

Beginning with fiscal 2008, the Company reports on a fiscal year ending May 31. Prior to fiscal 2008, the Company reported on a fiscal year that concluded on the Saturday nearest to May 31. Fiscal year 2007 ended on June 2, 2007, for a reporting period of fifty-two weeks.

3. Cash and Cash Equivalents

The Company considers all unrestricted highly liquid investments purchased with an initial maturity of less than three months to be cash equivalents. The Company maintains cash and cash equivalent balances with financial institutions in the United States in excess of amounts insured by the Federal Deposit Insurance Corporation.

4. Marketable Securities

Marketable securities, which are principally government agency bonds, auction rate investments and corporate commercial paper, are classified as “available-for-sale securities” in accordance with SFAS 115, “Accounting for Certain Investments in Debt and Equity Securities” and reported at fair value, with unrealized gains and losses excluded from operations and reported as a component of accumulated other comprehensive income (loss), net of the related tax effects, in stockholders’ equity. Cost is determined using the specific identification method. The Company holds investments in auction rate securities in order to generate higher than typical money market rate investment returns. Auction rate securities typically are high credit quality, generally achieved with municipal bond insurance. Credit risks are eased by the historical track record of bond insurers, which back a majority of this market. Sell orders for any security traded through an auction process could exceed bids and, in such cases, the auction fails and the Company may be unable to liquidate its position in the securities in the near term. During fiscal year 2009, the Company had $1.85 million in investments in two auction rate securities issued by New York state and local government authorities that failed auctions. The authorities are current in their interest payments on the securities.

5. Accounts Receivable

Accounts receivable, principally trade, are generally due within 30 to 90 days and are stated at amounts due from customers, net of an allowance for sales returns and doubtful accounts. The Company performs ongoing credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness, as determined by a review of their current credit information. The Company continuously monitors aging reports, collections and payments from customers, and a provision for estimated credit losses is maintained based upon the Company’s historical experience and any specific customer collection issues that have been identified. While such credit losses have historically been within the Company’s expectations and the provisions established, the Company cannot guarantee that the same credit loss rates will be experienced in the future. The Company writes off accounts receivable when they are determined to be uncollectible.

Ending Balance	$	602		$	683

6. Inventories

Inventories are stated at the lower of cost (at standard cost, which approximates the first-in, first-out method) or market. Appropriate consideration is given to deterioration, obsolescence and other factors in evaluating net realizable value.

7. Property, Plant and Equipment

Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The Company evaluates these assets for impairment annually or as changes in circumstances or the occurrence of events suggest the remaining value is not recoverable. Expenditures for repairs and maintenance are charged to expense as incurred. Renewals and betterments are capitalized.

8. Accounting for Business Combinations, Goodwill and Intangible Assets

Intangible assets, other than goodwill, are amortized over their estimated useful lives, which range between three and nineteen years, on either a straight-line basis over the period of expected benefit or as revenues are earned from the sales of the related products. The Company periodically reviews the estimated useful lives of its intangible assets and reviews such assets for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. The Company’s determination of impairment is based on estimates of future cash flows. If an intangible asset is considered to be impaired, the amount of the impairment will equal the excess of the carrying value over the fair value of the asset.

For goodwill, the evaluation requires a comparison of the estimated fair value of the reporting unit to which the goodwill is assigned to the sum of the carrying value of the assets and liabilities of that unit. If the sum of the carrying value of the assets and liabilities of a reporting unit exceeds the fair value of the reporting unit, the carrying value of the reporting unit’s goodwill is reduced to its implied fair value through an adjustment to the goodwill balance, resulting in an impairment charge. The Company’s determination of impairment is based on estimates of future cash flows. The Company tests goodwill for impairment during the third quarter of every fiscal year, or more frequently if impairment indicators arise. Events that could, in the future, result in impairment include, but are not limited to, sharply declining sales for a significant product or in a significant geographic region.

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination. Beginning in fiscal 2009 the Company began reporting

three operating segments. The reporting units are consistent with the Company’s operating segments, and include Peripheral Vascular, Access and Oncology/Surgery. As a result, the carrying value of goodwill was allocated to each of the reporting units on a relative fair value basis. The Company completed its annual evaluation of goodwill by reporting unit as of December 31, 2008. The assessment of goodwill impairment indicated that the fair value of each of the reporting units exceeded its carrying value and therefore goodwill in each of the reporting units was not impaired (See Note G). The fair value of Peripheral Vascular, Access and Oncology/Surgery exceeded its carrying value by 29%, 5% and 3%, respectively. The sum of the fair values of the reporting units was reconciled to the Company’s current market capitalization (based upon its stock price) plus an estimated control premium of approximately 19% as of December 31, 2008.

To determine fair value, the Company utilized two market-based approaches and an income approach. Under the market-based approaches, the Company utilized information regarding its own company as well as publicly available industry information to determine earnings multiples and sales multiples. Under the income approach, the Company determined fair value based on estimated future cash flows of each reporting unit, discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. The Company determined the discounted cash flow as the best indicator to determine fair value.

Determining the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growth rates, operating margins, discount rates and future market conditions, among others. Solely for purposes of establishing inputs for the fair value calculations, the Company assumed that the current economic conditions would continue through fiscal year 2010, followed by a recovery period in fiscal years 2011 and 2012. In addition, the Company applied gross margin assumptions consistent with its historical trends at various revenue levels and used a EBITDA exit multiple of 6.5, 7.0 and 8.0 to calculate the terminal value of the Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively, compared to an EBITDA exit multiple of 8.0 used in the prior year. In addition, the Company used a discount rate of 19%, 16% and 19% to calculate the fair value of the Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively. This discount rate is higher than the 14% discount rate used in the prior year, primarily due to the fact that additional risk premiums were added to take into account the economic downturn and specific inherent risks associated with each reporting unit.

Since early November 2008, the Company’s stock market capitalization has generally been lower than its shareholders’ equity or book value. However, the Company’s reporting units have continued to generate significant cash flow from their operations, and the Company expects that they will continue to do so in 2009 and beyond. Furthermore, given the relatively small difference between the Company’s stock price and its book value per share, the Company believes that a reasonable potential buyer would offer a control premium for its business that would adequately cover the difference between its trading prices and its book value.

Even though the Company determined that there was no goodwill impairment as of December 31, 2008, the future occurrence of a potential indicator of impairment, such as a significant adverse change in legal factors or business climate, an adverse action or assessment by a regulator, unanticipated competition, a material negative change in relationships with significant customers, strategic decisions made in response to economic or competitive conditions, loss of key personnel or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed of, would require an interim assessment for some or all of the reporting units prior to the next required annual assessment as of December 31, 2009. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.

9. Revenue Recognition

Revenue is recognized in accordance with generally accepted accounting principles as outlined in the SEC’s Staff Accounting Bulletin No. 104 “Revenue Recognition,” which requires that four basic criteria be met before revenue can be recognized: (i) persuasive evidence that an arrangement exists; (ii) the price is fixed or determinable; (iii) collectibility is reasonably assured; and (iv) product delivery has occurred or services have been rendered. The Company recognizes revenue, net of sales taxes assessed by any governmental authority, as products are shipped based on F.O.B. shipping terms when title and risk of loss passes to customers. The Company negotiates shipping and credit terms on a customer-by-customer basis and products are shipped at an agreed upon price. All product returns must be pre-approved and, if approved, customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and must have at least 12 months remaining prior to its expiration date.

10. Research and Development

Research and development costs, including salaries, consulting fees, building costs, utilities, administrative expenses, patent application costs, and an allocation of corporate costs are related to developing new products and making technological improvements to existing products and are expensed as incurred.

11. Shipping and Handling Costs

Shipping and handling costs, associated with the distribution of finished products to customers, are recorded in costs of goods sold and are recognized when the related finished product is shipped to the customer. Amounts charged to customers for shipping are recorded in net sales.

12. Advertising

All costs associated with advertisement are expensed as incurred. Advertising expense, included in sales and marketing expense was $909,000, $555,000, and $491,000 for fiscal 2009, 2008, and 2007, respectively.

13. Income Taxes

Deferred income taxes are recognized for temporary differences between financial statement and income tax bases of assets and liabilities and loss carryforwards and tax credit carryforwards for which income tax benefits are expected to be realized in future years. A valuation allowance has been established to reduce deferred tax assets, as it is more likely than not that all, or some portion, of such deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. The deferred tax asset includes net operating losses acquired as part of the RITA acquisition. These losses could be significantly limited under Internal Revenue Code (“IRC”) Section 382. An analysis of RITA’s ownership changes as defined in IRC Section 382 shows that approximately $15.8 million (of which $0.8 million had expired as of May 31, 2009) of net operating losses will not be utilized due to limitations. In addition, it is estimated that $11.8 million of state net operating losses will expire prior to utilization. The gross deferred tax asset related to the net operating losses reflects these limitations.

The Company intends to reinvest indefinitely any of its unrepatriated foreign earnings as of May 31, 2009. The Company has not provided for U.S. income taxes on these undistributed earnings of its foreign subsidiaries because Management considers such earnings to be reinvested indefinitely outside the United States. If these earnings were distributed, the Company may be subject to both foreign withholding taxes and U.S. income taxes. Determination of the amount of this unrecognized deferred income tax liability is not practical.

In November 2005, the FASB issued FASB Staff Position SFAS No. 123(R)-3, “Transition Election to Accounting for the Tax Effect of Share-Based Payment Awards”. The Company elected to adopt the modified prospective transition method for calculating the tax effects of stock-based compensation pursuant to SFAS No. 123(R). Under the modified prospective transition method, no adjustment is made to the deferred tax balances associated with stock-based payments that continue to be classified as equity awards. Additionally, the Company elected to use the “long-form method,” as provided in paragraph 81 of SFAS No. 123(R) to determine the pool of windfall tax benefits. The long-form method requires the Company to analyze the book and tax compensation for each award separately as if it had been issued following the recognition provisions of SFAS No. 123, subject to adjustments for net operating loss carryforwards.

14. Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, accounts receivable, marketable securities, accounts payable, short-term and long-term debt and two interest rate swap agreements. The carrying amount of these instruments approximates fair value due to the immediate or short-term maturities and variable interest rates associated with these instruments. The interest rate swap agreements have been recorded at their fair value based on a valuation received from an independent third party (see Note K). Marketable securities are carried at their fair value as determined by quoted market prices.

Effective June 1, 2008, the Company adopted SFAS No. 157, “Fair Value Measurements” (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. Fair value is defined under SFAS 157 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. SFAS 157 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value which are provided in the table below. The adoption of SFAS 157 had no impact on the Company’s financial statements other than the disclosures presented herein. There were no changes in the level 3 fair value instruments during the year ended May 31, 2009.

Level 1

Quoted prices in active markets for identical assets or liabilities. Level 1 assets include bank time deposits, mutual funds and U.S. Treasury securities that are traded in an active exchange market. Includes money market funds.

Level 2

Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Includes US government securities and corporate bonds. When quoted market prices are unobservable, we obtain pricing information from an independent pricing vendor. The pricing vendor uses various pricing models for each asset class that are consistent with what other market participants would use. The inputs and assumptions to the model of the pricing vendor are derived from market observable sources including: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and other market-related data. Since many fixed income securities do not trade on a daily basis, the methodology of the pricing vendor uses available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. The pricing vendor considers all available market observable inputs in determining the evaluation for a security. Thus, certain securities may not be priced using quoted

May 31, 2009 and May 31, 2008

prices, but rather determined from market observable information. These investments are included in Level 2 and primarily comprise our portfolio of corporate and government fixed income securities. Additionally included in Level 2 are interest rate swap agreements which are valued using a mid-market valuation model.

Level 3

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category currently only includes auction rate securities where independent pricing information was not able to be obtained. Our investments in auction-rate securities were classified as Level 3 as quoted prices were unavailable due to events described in Note A,Marketable Securities. Due to limited market information, we utilized a discounted cash flow (“DCF”) model to derive an estimate of fair value at May 31, 2009. The assumptions used in preparing the DCF model included estimates with respect to the amount and timing of future interest and principal payments, forward projections of the interest rate benchmarks, the probability of full repayment of the principal considering the credit quality and guarantees in place, and the rate of return required by investors to own such securities given the current liquidity risk associated with auction-rate securities.

In February 2007, the FASB issued Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, which allows an entity to elect to record financial assets and financial liabilities at fair value upon their initial recognition on a contract-by-contract basis. The Company did not elect to adopt Statement No. 159.

15. Derivative Financial Instruments

In March 2008, FASB issued Statement of Financial Accounting Standards No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). SFAS 161 is intended to improve financial reporting about derivative instruments and hedging activities by requiring companies to enhance disclosure about how these instruments and activities affect their financial position, performance and cash flows. SFAS 161 also improves the transparency about the location and amounts of derivative instruments in a company’s financial

80

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2009 and May 31, 2008

statements and how they are accounted for under SFAS 133. SFAS 161 is effective for both interim and annual reporting periods beginning after November 15, 2008. The Company provided the required disclosures in the May 31, 2009 consolidated financial statements.

The Company is exposed to market risk due to changes in interest rates. To reduce that risk, the Company periodically enters into certain derivative financial instruments to hedge its underlying economic exposure. The Company uses derivative instruments as part of its interest rate risk management strategy. The derivative instruments used are fixed-to-floating rate interest rate swaps, which are subject to fair-value and cash flow hedge accounting treatment. The company recognized interest expense of $378,000, $308,000 and interest income of $88,000 for the 2009, 2008 and 2007 periods, respectively, on the fair value hedge (See Note K).

In accordance with SFAS No. 133, “Accounting for Derivatives and Hedging Activities,” as amended, the Company’s 2002 interest rate swap agreement (see Note K) qualifies for hedge accounting under GAAP and the 2006 interest rate swap agreement does not. Both are presented in the consolidated financial statements at their fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in income or in stockholders’ equity as a component of accumulated other comprehensive income (loss) depending on whether the derivative financial instrument qualifies for hedge accounting and, if so, whether it qualifies as a fair value or cash flow hedge. Generally, the changes in the fair value of derivatives accounted for as fair value hedges are recorded in income along with the portions of the changes in the fair value of hedged items that relate to the hedged risks. Changes in the fair value of derivatives accounted for as cash flow hedges, to the extent they are effective as hedges, are recorded in accumulated other comprehensive income (loss).

16. Stock-Based Compensation

On June 4, 2006, the Company adopted Statement of Financial Accounting Standard No. 123 (revised 2004), “Share-Based Payments” (“SFAS 123(R)”), which requires the measurement and recognition of all share-based payment awards made to employees and directors, including stock options, restricted stock units, performance share awards and employee stock purchases related to the Company’s Employee Stock Purchase Plan (the “Stock Purchase Plan”) based on estimated fair values. SFAS 123(R) supercedes the Company’s previous accounting under Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”), “Accounting for Stock-based Compensation” (“SFAS No. 123”) for non-employees, and related interpretations, beginning fiscal year 2007. In March 2005, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 107 (“SAB 107”) relating to SFAS 123(R). The Company has applied the provisions of SAB 107 in its adoption of SFAS 123(R).

SFAS 123(R) requires companies to estimate the fair value of share-based payment awards on the date of the grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized on a straight-line basis over the requisite service period in the Company’s consolidated statements of operations. Prior to the adoption of SFAS 123(R), the Company accounted for stock-based awards to employees and directors using the intrinsic value method in accordance with APB 25 as allowed under SFAS 123. Under the intrinsic value method, no stock-based compensation expense had been recognized in the Company’s consolidated statements of operations, because the exercise price of the Company’s stock options granted to employees and directors was equal to or exceeded the fair market value of the underlying stock on the date of grant.

Stock-based compensation expense recognized in the Company’s consolidated statements of operations for periods after adoption of SFAS 123(R) includes compensation expense for share-based payment awards granted

81

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2009 and May 31, 2008

prior to, but not yet vested as of June 3, 2006, based on the grant date fair value estimated in accordance with the pro forma provisions of SFAS 123 and compensation expense for the share-based payment awards granted subsequent to June 3, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R), and has been reduced for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

For the fiscal years ended May 31, 2009, May 31, 2008 and June 2, 2007, the Company used the Black-Scholes option-pricing model (“Black-Scholes”) as its method of valuation under SFAS 123(R) and a single option award approach. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The fair value of share based payment awards on the date of the grant as determined by the Black-Scholes model is affected by the Company’s stock price as well as other assumptions. These assumptions include, but are not limited to the expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, and a risk-free interest rate. The risk-free interest rate is based on factual data derived from public sources. The expected stock-price volatility and option life assumptions require significant judgment and are considered critical accounting estimates.

The Company considers historical volatility of the Company’s stock price when estimating expected stock price volatility. The Company uses yield rates on U.S. Treasury securities for a period approximating the expected term of the award to estimate the risk-free interest rate. The expected term is determined using the simplified method available under SAB 107 due to our limited public history. The dividend yield is based on the history and expectation of dividend payments. The Company has not paid dividends in the past nor does it expect to pay dividends in the foreseeable future. Company historical data includes information from May 27, 2004, the date of the Company’s initial public offering.

17. Earnings Per Common Share

Basic earnings per share are based on the weighted average number of common shares outstanding without consideration of potential common stock. Diluted earnings per share further includes the dilutive effect of potential common stock consisting of stock options, warrants, restricted stock units and shares issuable upon conversion of convertible debt into shares of common stock, provided that the inclusion of such securities is not antidilutive.

The Company accounts for convertible debt (see Note K) under EITF Issue No. 04-08, “The Effect of Contingently Convertible Debt on Diluted Earnings per Share” (“EITF 04-08”). EITF 04-08 indicates that contingently convertible debt should be included in diluted earnings per share computations regardless of whether the market price trigger has been met. For fiscal 2008 and 2007, shares issuable upon conversion of convertible debt into 414,476 shares of common stock, with a conversion price of $20.41 per share, have been excluded from the calculation of diluted earnings per share, as their inclusion would not be dilutive. The Convertible debt was paid at maturity in fiscal 2009.

Also excluded from the calculation of diluted earnings per common share are options and warrants issued to employees and non-employees to purchase 1,389,571 shares of common stock at May 31, 2009 as their inclusion would not be dilutive. The exercise prices of the excluded securities were between $11.93 and $93.52 at May 31, 2009. For the periods ending May 31, 2008, and June 2, 2007, options, warrants and restricted stock units issued to employees and non-employees to purchase 2,481,787, and 1,111,342, respectively, were excluded from the calculation of diluted earnings per common share as their inclusion would not be dilutive. The exercise prices of the excluded securities were between $0 and $196.95 at both May 31, 2008 and June 2, 2007.

(1) As a result of the net loss for the year ending June 2, 2007, all outstanding options and warrants were excluded from the calculation of diluted earnings per common share as their inclusion would be antidilutive.

18. Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires 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 consolidated financial statements. Estimates also affect reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates.

19. Supplier Concentrations

The Company is dependent on a third-party manufacturer for a substantial portion of its dialysis catheters. In fiscal 2009, products purchased from this supplier accounted for approximately 20% of total product purchases and sales of these products accounted for approximately 10% of the Company’s sales. The Company is dependent upon the ability of its suppliers to provide products on a timely basis and on favorable pricing terms. The loss of its principal suppliers or a significant reduction in product availability from these suppliers could have a material adverse effect on the Company. The Company believes that its relationships with these suppliers are satisfactory.

20. Recently Issued Accounting Pronouncements

In November 2007, the Emerging Issues Task Force (EITF) reached a consensus on EITF Issue No. 07-01, “Accounting for Collaborative Arrangements” (EITF No. 07-01). EITF No. 07-01 establishes disclosure requirements for arrangements entered into by companies to collaboratively develop, manufacture, or market products. EITF No. 07-01 also establishes income statement classification of collaboration transactions between the parties. EITF No. 07-01 is effective for fiscal years beginning after December 15, 2008 (the Company’s 2010 fiscal year). The Company is currently evaluating the impact this adoption will have on the Company’s consolidated financial statements.

In December 2007, FASB issued Statement of Financial Accounting Standards No. 141(R), “Business Combinations” (“SFAS 141(R)”). SFAS 141(R) establishes principles and requirements for how the acquirer in a business combination recognizes and measures the assets acquired, liabilities assumed and any noncontrolling interest in the acquiree; recognizes and measures the goodwill acquired or gain from a bargain purchase; and determines what information to disclose to enable readers of the financial statements to evaluate the nature and financial effects of the business combination. SFAS 141(R) is effective for business combinations for which the acquisition date is on or after fiscal years beginning after December 15, 2008 (the Company’s 2010 fiscal year) and will be applied prospectively, with the exception of the accounting for valuation allowances on deferred

83

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2009 and May 31, 2008

taxes and acquired tax contingencies. FAS 141(R) amends FAS 109 such that adjustments made to valuation allowances on deferred taxes and acquired tax contingencies associated with acquisitions that closed prior to the effective date of FAS 141(R) would also apply the provisions of FAS 141(R).

In December 2007, FASB issued Statement of Financial Accounting Standards No. 160, “Noncontrolling Interests in Consolidated Financial Statements – an amendment of ARB No. 51” (“SFAS 160”). SFAS 160 establishes accounting and reporting standards that require companies to more clearly identify in the financial statements and discloses the impact of noncontrolling interest in a consolidated subsidiary on the consolidated financial statements. SFAS 160 is effective for fiscal years beginning after December 15, 2008 (the Company’s 2010 fiscal year), and interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on the Company’s financial statements.

In February 2008, the FASB issued FASB Staff Position No. FAS 157-2, “Effective Date of FASB Statement No. 157” (“FSP No. 157-2”), which deferred the effective date of SFAS No. 157 for one year for non-financial assets and liabilities, except for certain items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). The Company is currently evaluating the impact of SFAS No. 157 on its consolidated financial statements for items within the scope of FSP No. 157-2 which will become effective on June 1, 2009 (the Company’s 2010 fiscal year).

In June 2008, the FASB issued Staff Position EITF No. 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities” (“EITF No. 03-6-1”). EITF No. 03-6-1 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and therefore need to be included in the earnings allocation in calculating earnings per share under the two class method described in SFAS No. 128, “Earnings per Share.” EITF No. 03-6-1 requires companies to treat unvested share-based payment awards that have non-forfeitable rights to dividend or dividend equivalents as a separate class of securities in calculating earnings per share. It is effective for calendar-year companies beginning January 1, 2009 (the Company’s 2010 fiscal year). The Company is currently assessing the potential impact of implementing this standard.

In June 2008, the FASB ratified Emerging Issues Task Force (“EITF”) Issue No. 07-05, “Determining Whether an Instrument (or Embedded Feature) is Indexed to an Entity’s Own Stock” (“EITF 07-05”). EITF 07-05 mandates a two-step process for evaluating whether an equity-linked financial instrument or embedded feature is indexed to the entity’s own stock. Warrants that a company issues that contain a strike price adjustment feature, upon the adoption of EITF 07-05, results in the instruments no longer being considered indexed to the company’s own stock. Accordingly, adoption of EITF 07-05 will change the current classification (from equity to liability) and the related accounting for such warrants outstanding at that date. EITF 07-05 is effective for fiscal years beginning after December 15, 2008 (the Company’s 2010 fiscal year), and interim periods within those fiscal years. The Company is currently assessing the potential impact of implementing this standard.

In April 2009, the FASB issued FSP SFAS No. 157-4, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions that are Not Orderly” (“FSP SFAS No 157-4”). FSP SFAS No 157-4 provides guidance for estimating fair value in accordance with SFAS No. 157 when the volume and level of activity for the asset or liability have significantly decreased when compared with normal market activity for the asset or liability and for identifying circumstances that indicate a transaction is not orderly. Additionally, FSP SFAS No. 157-4 amends SFAS No. 157 to require disclosure in interim and annual periods of the inputs and valuation techniques used to measure fair value. FAS SFAS No.157-4 is effective for interim and annual periods ending after June 15, 2009 (the Company’s 2010

fiscal year) and will be applied prospectively. The adoption of this pronouncement is not expected to have a material impact on the Company’s financial statements.

In April 2009, the FASB issued FSP SFAS No. 141(R)-1, “Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies” (“FSP SFAS No. 141(R)-1”). FSP SFAS No. 141 (R)-1 amends and clarifies the initial recognition and measurement, subsequent measurement and accounting and disclosure of assets and liabilities arising from contingencies in a business combination under SFAS No. 141(R). FSP SFAS No 141(R)-1 is effective for acquisitions dates on or after the beginning of the first annual reporting period beginning on or after December 15, 2008 (the Company’s 2010 fiscal year).

In April 2009, the FASB issued FSP SFAS No. 107-1 and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments” (“FSP SFAS No 107-1 and APB 28-1”). FSP SFAS No 107-1 and APB 28-1 requires disclosures about fair value of financial instruments for interim period reporting as well as in annual financial statements. Additionally, this FSP requires disclosures regarding the methods and significant assumptions used to estimate the fair value of financial instruments. FSP SFAS No 107-1 and APB 28-1 is effective for interim and annual periods ending after June 15, 2009 (the Company’s 2010 fiscal year) but only requires the revised disclosures on a prospective basis. The Company will provide the additional disclosures necessary to the consolidated financial statements beginning in the Company’s first quarter of fiscal year 2010.

In April 2009, the FASB issued FSP SFAS No. 115-2 and SFAS No. 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments” (“FSP SFAS Nos. 115-2 and 124-2”). FSP SFAS Nos. 115-2 and 124-2 amends the other-than-temporary guidance for debt securities and requires additional interim and annual disclosures of other-than-temporary impairments on debt and equity securities. Under FSP SFAS Nos. 115-2 and 124-2, an other-than-temporary impairment of a debt security shall be considered to have occurred if an entity (1) intends to sell the debt security, (2) more likely than not will be required to sell the security before recovery of its amortized cost basis or (3) does not expect to recover the entire amortized cost basis of the security even if it does not intend to sell the security. Once it is determined than an other-than-temporary impairment has occurred, FSP SFAS Nos. 115-2 and 124-2 provides guidance on when to recognize the other-than-temporary impairment in earnings or in other comprehensive income. Depending on which of the above factors(s) caused the impairment to be considerer other –than-temporary, (1) the entire shortfall of the security’s fair value versus its amortized cost basis or (2) only the credit loss portion would be recognized in earnings while the remaining shortfall (if any) would be recorded in other comprehensive income. FSP SFAS Nos. 115-2 and 124-2 is effective for interim and annual periods ending after June 15, 2009 (the Company’s 2010 fiscal year) and is required to be applied retrospectively to existing investments with a cumulative adjustment to retained earnings and prospectively to new investments purchased after the effective date. The Company is currently evaluating the impact this adoption will have on the Company’s consolidated financial statements.

In May 2009, the FASB issued SFAS No. 165 “Subsequent Events” (“SFAS No. 165”). SFAS No. 165 requires an entity to recognize in the financial statements the effects of all subsequent events that provide additional evidence about conditions that existed at the date of the balance sheet. For nonrecognized subsequent events that must be disclosed to keep the financial statements from being misleading, an entity will be required to disclose the nature of the event as well as an estimate of its financial effect, or a statement that such an estimate cannot be made. In addition, SFAS No. 165 requires an entity to disclose the date through which subsequent events have been evaluated. SFAS No. 165 is effective for interim and annual periods ending after June 15, 2009 (the Company’s 2010 fiscal year) and is required to be applied prospectively. The adoption of this pronouncement is not expected to have a material impact on the Company’s financial statements.

NOTE C—ACQUISITIONS

FlowMedica, Inc.

On January 12, 2009 the Company completed the acquisition of certain assets of FlowMedica, Inc. for approximately $1.75 million in cash and a contingent payment based on fiscal 2011 sales of FlowMedica products. With this acquisition, the Company purchased the Benephit product line, a therapeutic approach to deliver drugs directly to the kidneys in order to prevent and treat acute kidney injury, in the emerging field of Targeted Renal Therapy. Intangible assets acquired totaled approximately $1.3 million which have been identified as product technologies (10-year weighted average useful life). Inventory acquired totaled approximately $400,000. The acquisition is being accounted for as a purchase and accordingly, the Company has included the results of operations in the financial statements effective January 12, 2009, the date of acquisition. The pro-forma effects of the acquisition were not material to the Company’s income statement and balance sheet. Ten employees of FlowMedica, Inc. became employees of the Company upon completion of the acquisition.

Diomed, Inc. and Diomed UK Limited.

On June 17, 2008, the Company completed the acquisition of certain U.S. assets of Diomed, Inc. and UK assets of Diomed UK Limited, in separate transactions, for an aggregate purchase price of approximately $11.1 million in cash including capitalized acquisition costs. With this acquisition, the Company substantially strengthened its position in the market for the treatment of varicose veins. The combination of Diomed endovenous laser products with the Company’s existing venous product line provides the Company with a comprehensive venous product offering. The total of the net assets acquired was $5.5 million.

Goodwill recorded as a result of these acquisitions was approximately $1.9 million. Intangibles assets acquired, other than goodwill, totaled approximately $3.7 million of which $3.6 million has been identified as customer relationships (8-year estimated weighted average useful life) and $100,000 has been identified as product technologies (10-year estimated weighted average useful life).

The pro-forma effects of the Diomed acquisition on the Company’s income statement and balance sheet were not material. Thirty five employees of Diomed became employees of the Company upon completion of the acquisitions.

Oncobionic, Inc.

On May 9, 2008, the Company completed the acquisition of all the issued and outstanding shares of capital stock of Oncobionic, Inc. pursuant to the terms of the Stock Purchase Agreement entered into on October 12, 2006. The closing of the acquisition came as a result of the successful use of irreversible electroporation (IRE) technology in the first human clinical trial for the treatment of soft tissue, conducted during the first week of April 2008. Under the October 2006 Stock Purchase Agreement, the Company agreed to pay a total purchase price of $25.4 million, including $400,000 of assumed liabilities. The Company made payments of $5.0 million upon the execution of the stock purchase agreement in October 2006, $10.0 million on May 9, 2008 upon the closing of the acquisition and $5.0 million in November 2008. The remaining $5.0 million is payable in November 2009 and included on the balance sheet under the caption “Other current liabilities” as of May 31, 2009.

The Stock Purchase Agreement also provides for future royalty payments due on net sales of any catheter-based products sold by the Company that incorporate irreversible electroporation technology (“IRE”). The Company holds a license to such technology under a license agreement with the Regents of the University of California (the “UC License”).

The Company has accounted for the acquisition of Oncobionic as a purchase under accounting principles generally accepted in the United States of America. Under the purchase method of accounting, the assets and liabilities of Oncobionic were recorded as of the acquisition date, at their respective fair values, and consolidated with those of AngioDynamics. $25.2 million of the purchase price was recorded as product technology and is being amortized over a 15 year useful life. The Company has recorded goodwill and a deferred tax liability of $9.3 million. In future periods the deferred tax liability will be reduced to offset the tax impact of non-deductible amortization expense on the intangible assets acquired. The pro-forma impact on prior year results of operations would be approximately $1,680,000 of additional amortization expense or $1,040,000, net of tax.

RITA Medical Systems, Inc.

On January 29, 2007, the Company completed the acquisition of RITA Medical Systems, Inc. (“RITA”) for a total purchase price of approximately $244 million, comprised of approximately $24 million in cash, 7.9 million shares of the Company’s common stock and assumption of outstanding RITA options and other convertible securities. As of May 31, 2009, the RITA options are exercisable for an additional 267,850 shares of the Company’s common stock. In connection with the acquisition, the Company assumed warrants to acquire 2,727,270 RITA shares, which became exercisable for approximately 469,636 shares of the Company’s common stock at an average price of $20.24 per share, net of the cash component. These warrants expire in November 2009. The aggregate fair value with respect to the warrants of approximately $4.5 million was recorded as part of the purchase price using fair values determined under the Black-Scholes valuation model, with the following assumptions: expected stock price volatility of 54.6%; risk-free interest rate of 4.98%; and an expected term of 1.7 years.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2009 and May 31, 2008

The Company accounted for the acquisition of RITA as a business combination under accounting principles generally accepted in the United States of America. Under the purchase method of accounting, the assets and liabilities of RITA were recorded as of the acquisition date, at their respective fair values, and consolidated with those of AngioDynamics. The valuation of the assets and liabilities of RITA required the use of significant assumptions and estimates, including expected future cash flows and the applicable discount rates for the acquired intangibles, Black-Scholes assumptions for the valuation of the exchanged options and warrants and estimates for IRC section 382 limitations for the deferred tax assets. These estimates were based on assumptions that the Company believed to be reasonable as of the date of the acquisition. However, the Company’s actual results may differ from these estimates.

The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed:

Current assets	$	18,164
Property, plant and equipment		1,638
Deferred tax asset		28,560
Goodwill		153,392
Customer relationships		27,500
Distributor relationships		900
Product technologies		13,900
Trademarks		600
Purchased R&D		12,100
Other assets		1,040
Total assets acquired		257,794
Current liabilities		4,588
Long-term convertible debt		9,700
Total liabilities assumed		14,288
Net assets acquired	$	243,506

The fair values of the Company’s common stock issued, the options and warrants assumed, and the fair value of the convertible debt assumed in the acquisition of RITA were calculated using a valuation price of $24.776 per share of the Company’s common stock, which was calculated using the average of the closing market value for two days prior to and two days after the measurement date of January 24, 2007. The purchase price of $243.5 million includes $4.6 million of direct acquisition costs. The product technologies are expected to be amortized over a weighted-average useful life of 11 years. The remaining intangible assets are being amortized over a weighted-average useful life of 7 years. In addition, originally the Company recorded $153.8 million in non-tax deductible goodwill, which was adjusted during 2008 for the impact of SFAS 123(R). The Company also recorded approximately $12.1 million of purchased research and development (“purchased R&D”) costs which were recorded in research and development expense in its consolidated statements of operations for the fiscal year ended June 2, 2007. The value assigned to purchased R&D was determined by identifying specific R&D projects that would be continued and for which (a) technological feasibility had not been established at the acquisition date, (b) there was no alternative future use and (c) the fair market value was estimable with reasonable reliability. The Company considered a number of factors including comparable transactions, relief from royalty analysis and other discounted cash flow approaches in determining preliminary purchase price allocations.

NOTE G—GOODWILL AND INTANGIBLE ASSETS

Goodwill and intangible assets that have indefinite useful lives are not amortized but rather are tested for impairment annually or more frequently if impairment indicators arise. None of the Company’s intangible assets have an indefinite life. Intangible assets with determinable useful lives are amortized over their useful lives on either a straight-line basis over the expected period of benefit or as revenues are earned from the sales of the related products. Goodwill and intangible assets have been recorded at either incurred or allocated cost. Allocated costs were based on respective fair market values at the date of acquisition.

Beginning in fiscal 2009 the Company began reporting three operating segments. The Company’s reporting units are consistent with the Company’s operating segments, and include Peripheral Vascular, Access and Oncology/Surgery. As a result, the carrying value of goodwill was allocated to each of the Company’s reporting units on a relative fair value basis. The Company completed its annual evaluation of goodwill by reporting unit as of December 31, 2008. The Company’s assessment of goodwill impairment indicated that the fair value of

90

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2009 and May 31, 2008

each of the Company’s reporting units exceeded its carrying value and therefore goodwill in each of the reporting units was not impaired. The fair value of Peripheral Vascular, Access and Oncology/Surgery exceeded its carrying value by 29%, 5% and 3%, respectively. The sum of the fair values of the reporting units was reconciled to the Company’s current market capitalization (based upon the Company’s stock price) plus an estimated control premium of approximately 19% as of December 31, 2008.

To determine fair value, the Company utilized two market-based approaches and an income approach. Under the market-based approaches, the Company utilized information regarding the Company as well as publicly available industry information to determine earnings multiples and sales multiples. Under the income approach, the Company determined fair value based on estimated future cash flows of each reporting unit, discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. The Company determined the discounted cash flow as the best indicator to determine fair value.

Determining the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growth rates, operating margins, discount rates and future market conditions, among others. Solely for purposes of establishing inputs for the fair value calculations, the Company assumed that the current economic conditions would continue through fiscal year 2010, followed by a recovery period in fiscal years 2011 and 2012. In addition, the Company applied gross margin assumptions consistent with the Company’s historical trends at various revenue levels and used a EBITDA exit multiple of 6.5, 7.0 and 8.0 to calculate the terminal value of the Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively, compared to an EBITDA exit multiple of 8.0 used in the prior year. In addition, the Company used a discount rate of 19%, 16% and 19% to calculate the fair value of its Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively. This discount rate is higher than the 14% discount rate used in the prior year, primarily due to the fact that additional risk premiums were added to take into account the economic downturn and specific inherent risks associated with each reporting unit.

Since early November 2008, our stock market capitalization has generally been lower than our shareholders’ equity or book value. However, our reporting units have continued to generate significant cash flow from their operations, and we expect that they will continue to do so in 2009 and beyond. Furthermore, given the relatively small difference between our stock price and our book value per share, we believe that a reasonable potential buyer would offer a control premium for our business that would adequately cover the difference between our trading prices and our book value.

Goodwill and deferred acquisition costs by segment are as follows:

	May 31, 2009
Peripheral Vascular	$	56,259
Access		51,723
Oncology/Surgery		53,992
	$	161,974

Even though the Company determined that there was no goodwill impairment as of December 31, 2008, the future occurrence of a potential indicator of impairment, such as a significant adverse change in legal factors or business climate, an adverse action or assessment by a regulator, unanticipated competition, a material negative

change in relationships with significant customers, strategic decisions made in response to economic or competitive conditions, loss of key personnel or a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed of, would require an interim assessment for some or all of the reporting units prior to the next required annual assessment as of December 31, 2009. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.

Changes in the carrying amount of goodwill for the fiscal year ended May 31, 2009, are as follows (in thousands):

Balance, May 31, 2008	$	162,707
Adjustments to purchase price allocation		(2,602	)
Arising from completed business combinations (Note C)		1,869
Balance, May 31, 2009	$	161,974

During the fiscal year ended May 31, 2009, the Company benefitted from the tax deduction of costs incurred related to the acquisition of Rita Medical Systems, Inc. These deductions resulted in a decrease in taxes payable and an increase in the acquired deferred tax asset and thereby reduced the recorded value of goodwill. This change is reflected above as an adjustment to purchase price allocation.

As a result of ownership changes caused by the acquisition of RITA, these net operating losses are subject to Internal Revenue Code (“IRC”) Section 382 limitations, which is expected to significantly limit the Company’s ability to utilize these net operating losses on an annual basis. As a result of the Company’s IRC Section 382 analysis, it is estimated that approximately $15.0 million of remaining Federal net operating losses and $11.8 million of state net operating losses will expire prior to utilization. The gross deferred income tax asset (“DTA”) related to the NOL reflects these limitations.

The Company needs to generate approximately $4 million of taxable income in each year over the next seventeen years to ensure the realizability of the Company’s deferred tax assets. The Company has determined that it has sufficient existing levels of pre-tax earnings to generate sufficient taxable income to realize the net deferred tax assets recorded on the Company’s balance sheets.

In order to support the realizability of the Company’s net deferred tax asset, management projected its pre-tax income utilizing a combination of historical and projected results. Utilizing this projected pre-tax income, management has projected taxable income taking into consideration existing levels of permanent differences including stock option exercise deductions and non-deductible expenses and the reversal of significant temporary differences.

The Company’s Federal net operating loss carryforwards as of May 31, 2009 after considering IRC Section 382 limitations are $65.0 million. The expiration of the Federal net operating loss carryforwards are as follows: $0.6 million between 2010 and 2011, $29.8 million between 2017 and 2021 and $34.6 million between 2022 and 2026.

The Company’s state net operating loss carryforwards as of May 31, 2009 after considering remaining IRC Section 382 limitations are $15.6 million which expire in various years from 2010 to 2026.

At May 31, 2009, the Company had approximately $429,000 of Federal research and development tax credit carryforwards which are subject to IRC Section 382 limitations and begin to expire in 2023 and approximately $571,000 of Federal research and development credit carryforwards which are not subject to these limitations and begin to expire in 2023. Additionally, at May 31, 2009, the Company had $1.3 million of state credits, of which $315,000 expire at various dates through 2013 and $996,000 which have an unlimited carryforward period.

At May 31, 2009, the Company had a net deferred income tax asset of $13.6 million, after recording a valuation allowance of $1.2 million (of which $1.1 million relates to deferred tax assets acquired in connection with the RITA acquisition). The net change in the valuation allowance was an increase of $17,000 in 2009 and a decrease of $1.0 million in 2008. The 2009 increase relates to fiscal year 2009 capital losses which are fully reserved. The 2008 decrease in the valuation allowance was based upon a change in management’s estimate of the realizability of certain Federal tax credits and state net operating losses obtained in connection with the RITA acquisition. Consequently this change was reflected as a reduction to goodwill related to the acquisition. The valuation allowance recorded against the deferred tax assets acquired in connection with the RITA acquisition relates to state tax credits and state NOLs that management has estimated will more likely than not expire before they are expected to be utilized.

The Company’s consolidated income tax provision has differed from the amount that would be provided by applying the U.S. Federal statutory income tax rate to the Company’s income before income taxes for the following reasons:

In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109” (FIN 48), which clarifies the accounting for uncertainty in tax positions. FIN 48 seeks to reduce the diversity in practice associated with certain aspects of the recognition and measurement related to accounting for income taxes. This Interpretation requires the Company recognize in its financial statements the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. This Interpretation is effective for fiscal years beginning after December 15, 2006, with the cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. The Company adopted this statement on June 3, 2007. There was no cumulative effect of adopting FIN 48. Upon adoption, the liability for unrecognized tax benefits was zero.

During the twelve months ended May 31, 2009, the Company did not recognize any tax liabilities related to uncertain tax positions. Due to the unrecognized tax benefit of the Company being zero upon adoption, with no change since adoption, no “tabular reconciliation” of the total amount of unrecognized tax benefits at the beginning and end of the period is being presented.

The Company recognizes interest and penalties related to unrecognized tax benefits within its global operations as a component of income tax expense. This accounting policy did not change as a result of the adoption of FIN 48. Accrued interest and penalties recognized in the consolidated balance sheet were $0 as of May 31, 2009 and May 31, 2008.

The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business the Company is subject to examination by taxing authorities throughout the world. The Internal Revenue Service (“IRS”) completed an examination of the Company’s federal income tax returns for fiscal years 2006 and 2007 in February 2009 which did not result in a material impact on the Company’s results of operations or financial position. Fiscal years 2006 through 2009 remain open to examination by the various tax authorities. The Company analyzed filing positions in all of the federal and state jurisdictions where it is required to file income taxes, as well as all open tax years in these jurisdictions and believes that its income tax filings positions and deductions will be sustained on audit and does not anticipate any adjustments will result in a material adverse effect on the Company’s financial condition, results of operations or cash flows.

Management does not anticipate that the amount of unrecognized tax benefits will significantly change in the next twelve months.

NOTE I—PREPAID ROYALTIES

On August 13, 2007, the Company entered into a Distribution, Manufacturing and Purchase Option Agreement (“the Agreement”) with a company to acquire the exclusive worldwide rights to manufacture and distribute a split tip catheter for the dialysis market that the Company has named Centros™. The Company also has the option to purchase certain intellectual property associated with these products in the future. The Company will pay royalties on net sales of the products covered in the Agreement. In accordance with the Agreement, the Company has prepaid $3.0 million of royalties based upon the achievement of certain milestones. These payments have been included in the caption “Prepaid Royalties” on the balance sheet as of May 31, 2009 and will be credited against quarterly royalties due subject to certain contractual limitations in the first two years following the initial sale of product. In years 4 through 10 of the contract, certain minimum annual royalties are due.

NOTE K—LONG-TERM DEBT

Industrial Revenue Bonds

In September 2002, the Company closed on the financing for the expansion of its headquarters and manufacturing facility in Queensbury, New York. The expansion was financed principally with Industrial Revenue Bonds (the “Bonds”) issued by the Warren and Washington Counties Industrial Development Agency (the “Agency”) aggregating $3,500,000. The Bonds are issued under a Trust Agreement by and between the Agency and a bank, as trustee (the “Trustee”). The proceeds of the Bonds were advanced, as construction occurred, pursuant to a Building Loan Agreement by and among the Agency, the Trustee, a second bank (the “Bank”) and the Company. The Bonds reprice every seven days and are resold by a Remarketing Agent. The Bonds bear interest based on the market rate on the date the Bonds are repriced and require quarterly interest payments and quarterly principal payments ranging from $25,000 to $65,000 through May 2022. In connection with the issuance of the Bonds, the Company entered into a Letter of Credit and Reimbursement Agreement with the Bank which requires the maintenance of a letter of credit for an initial amount of $3,575,000 to support principal and certain interest payments of the Bonds and requires payment of an annual fee on the outstanding balance ranging from 1% to 1.9%, depending on financial results achieved. The Company also entered into a Remarketing Agreement, pursuant to which the Remarketing Agent is required to use its best efforts to arrange for sales of such bonds in the secondary market. The Remarketing Agreement provides for the payment of an annual fee of 0.1% of the remaining balance.

The Reimbursement Agreement contains certain financial covenants relating to fixed charge coverage and interest coverage, as defined. Amounts borrowed under the Agreement are collateralized by the aforementioned letter of credit and a first mortgage on the land, building and equipment relating to the facility.

The Company entered into an interest rate swap agreement (the “2002 Swap Agreement”) with the Bank, effective September 2002, with an initial notional amount of $3,500,000 to limit the effect of variability due to interest rates on its rollover of the Bonds. The Swap Agreement, which qualifies for hedge accounting under SFAS No. 133, is a contract to exchange floating interest rate payments for fixed interest payments periodically over the life of the agreement without the exchange of the underlying notional amounts. The Swap Agreement requires the Company to pay a fixed rate of 4.45% and receive payments based on 30-day LIBOR repriced every seven days through May 2022. As of May 31, 2009, May 31, 2008 and June 2, 2007, since the Swap Agreement is classified as a cash flow hedge, the fair value of $319,000, $196,000 and $98,000, respectively, has been recorded as a component of accrued liabilities, and accumulated other comprehensive loss related to the swap agreement is $201,000, $123,000 and $61,000, respectively, net of tax.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2009 and May 31, 2008

The Company capitalized certain legal and administrative costs incurred in connection with the issuance of the Bonds and is amortizing these costs using the effective interest method over the term of the Bonds. As of May 31, 2009, May 31, 2008 and June 2, 2007, net capitalized bond issuance costs amounted to $74,000, $80,000 and $85,000, respectively, and are recorded as a component of other assets.

Amounts to be paid or received under the Swap Agreement are accrued as interest rates change and are recognized over the life of the Swap Agreement as an adjustment to interest expense.

Taxable Adjustable Rate Notes

In December 2006, the Company closed on the financing for the expansion of its warehouse and manufacturing facility in Queensbury, New York. The expansion is being financed principally with Taxable Adjustable Rate Notes (the “Notes”) issued by the Company aggregating $5,000,000, maturing in December 2026. The Notes were issued under a Trust Agreement by and between the Company and a bank, as trustee (the “Trustee”). The Notes reprice every seven days and are resold by a Remarketing Agent. The Notes bear interest based on the market rate on the date the Notes are repriced and require quarterly interest payments and quarterly principal payments ranging from $25,000 to $55,000. In connection with the issuance of the Notes, the Company entered into a Letter of Credit and Reimbursement Agreement with the Bank that requires the maintenance of a letter of credit for an initial amount of $5,134,000 to support principal and certain interest payments on the Notes and requires payment of an annual fee on the outstanding balance ranging from 0.75% to 1.35%. The Company also entered into a Remarketing Agreement, pursuant to which the Remarketing Agent is required to use its best efforts to arrange for sales of the Notes in the secondary market. The Remarketing Agreement provides for the payment of an annual fee of 0.1% of the remaining balance.

The Reimbursement Agreement contains certain financial covenants relating to fixed charge coverage, interest coverage, and a debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”) ratio, as defined. Amounts borrowed under the Reimbursement Agreement are collateralized by the aforementioned letter of credit and all Company assets.

The Company entered into an interest rate swap agreement (the “2006 Swap Agreement”) with the Bank, effective December 2006, with an initial notional amount of $5,000,000, to limit the effect of variability due to interest rates on its rollover of the Notes. The 2006 Swap Agreement is a contract to exchange floating interest rate payments for fixed interest payments of 5.06% of the outstanding balance of the Notes over the life of the agreement without the exchange of the underlying notional amounts. Changes to the fair value of the 2006 Swap Agreement are recorded as increases or decreases to interest expense as the Company did not elect to apply hedge accounting. As of May 31, 2009 and May 31, 2008, the fair value of $599,000 and $221,000, respectively has been recorded as a component of accrued liabilities with a corresponding credit to other income in the consolidated statement of operations.

The Company capitalized certain legal and bank fees incurred in connection with the issuance of the Notes and is amortizing these costs on a straight-line basis over the term of the Notes. As of May 31, 2009 and May 31, 2008, net capitalized issuance costs related to these Notes amounted to $168,000 and $178,000, respectively, and are recorded as a component of other assets.

Convertible Notes

In connection with the acquisition of RITA on January 29, 2007, the Company assumed subordinated Senior Convertible Notes of RITA (the “Convertible Notes”) with an aggregate principal amount of $9.7 million. The

NOTE N—STOCKHOLDERS’ EQUITY

1. Capitalization

On February 27, 2004, the Company’s Board of Directors and the Former Parent, as sole stockholder, approved the Company’s Amended and Restated Certificate of Incorporation (the “Amended Certificate”). Under the Amended Certificate, the authorized capital stock of the Company is 50,000,000 shares, consisting of 45,000,000 shares of common stock, par value $.01 per share and 5,000,000 shares of preferred stock, par value $.01 per share. Pursuant to the Amended Certificate, (i) each share of voting common stock, $1 par value and (ii) each share of non-voting common stock, $1 par value was reclassified and exchanged into 9,200 shares of issued, fully paid, non-assessable common stock for a total of 9,200,000 shares to be then outstanding.

The holders of common stock are entitled to one vote for each share held. Subject to preferences applicable to any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably

dividends, if any, as may be declared by the Board of Directors out of funds legally available for dividend payments. If the Company liquidates, dissolves, or winds up, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities and liquidation preferences of any outstanding shares of preferred stock. Holders of common stock have no pre-emptive rights or rights to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to the common stock. The rights, preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that the Company may designate in the future.

The Company’s board of directors has the authority to (i) issue the undesignated preferred stock in one or more series, (ii) determine the powers, preferences and rights and the qualifications, limitations or restrictions granted to or imposed upon any wholly un-issued series of undesignated preferred stock and (iii) fix the number of shares constituting any series and the designation of the series, without any further vote or action by the Company’s stockholders.

2. Stock Options

The Company has two stock-based compensation plans, exclusive of the stock option plans assumed in connection with the acquisition of RITA. These plans provide for the issuance of up to approximately 4.5 million shares of common stock.

1997 Stock Option Plan

In 1997, the Company adopted a Stock Option Plan (the “1997 Plan”). The 1997 Plan provides for the grant to key employees of both nonqualified stock options and incentive stock options and to members of the Board of Directors and consultants of nonqualified stock options. A total of 1,497,674 shares of the Company’s common stock may be issued under the 1997 Plan pursuant to the exercise of options. All stock options must have an exercise price of not less than the fair market value of the shares on the date of grant. Options will be exercisable over a period of time to be designated by the administrators of the 1997 Plan (but not more than 10 years from the date of grant) and will be subject to such other terms and conditions as the administrators may determine. The vesting schedule is subject to the discretion of the Company’s Board of Directors. Options are exercisable immediately upon vesting. In addition, all options, whether vested or not, become exercisable in full immediately upon a change of control, as defined under the 1997 Plan. The 1997 Plan terminated in March 2007 and as such, no further options will be granted under this plan.

2004 Stock and Incentive Award Plan

The 2004 Stock and Incentive Award Plan (the “2004 Plan”) provides for the grant of incentive options to the Company’s employees and for the grant of non-statutory stock options, restricted stock, stock appreciation rights, performance units, performance shares and other incentive awards to the Company’s employees, directors and other service providers. A total of 3,000,000 shares of the Company’s common stock have been reserved for issuance under the 2004 Plan, of which up to 800,000 shares may be issued upon the exercise of incentive stock options. The compensation committee of the Board of Directors administers the 2004 Plan. The committee determines vesting terms and the exercise price of options granted under the 2004 Plan, but for all incentive stock options the exercise price must at least be equal to the fair market value of the Company’s common stock on the date of grant. The term of an incentive stock option may not exceed ten years.

RITA Stock Option Plans

In connection with the acquisition of RITA, the Company assumed all outstanding options to acquire RITA common stock (the “RITA Options”). Except for RITA Options that were fully vested due to employee terminations and change-of-control provisions in connection with the completion of the acquisition of RITA, options under these plans maintain their original vesting provisions and generally expire ten years from the original date of grant. The Company does not anticipate future grants will be made under these plans. As of May 31, 2009, RITA Options to acquire 267,850 shares of Company common stock were outstanding, of which RITA Options to acquire 249,489 shares of Company common stock were exercisable.

In accordance with the Merger Agreement, the options held by RITA employees became exercisable for shares of the Company’s common stock and a fixed cash component payable to the holder at option exercise (see Note C). Under SFAS 123(R), an exchange of stock-based compensation awards in a combination is treated as a modification. Based upon the fact that the receipt of cash is contingent upon the exercise of the option, and not the vesting of such option, the RITA Options were classified as equity. The Company calculated the fair value of the RITA options immediately prior to the modification, utilizing fair value assumptions at the time the merger was being contemplated and the fair value of the replacement awards. It was determined there was no incremental compensation cost required to be recognized for either the vested or unvested options.

The fair value of the RITA options assumed in connection with the acquisition of RITA was calculated using the Black-Scholes model with the following weighted-average assumptions:

Stock options assumed in acquisition		988,815
Weighted-average fair value	$	12.63
Black-Scholes Assumptions:
Expected stock price volatility		50.60	%

On May 31, 2009, there remained 428,098 shares available for granting of options under the 2004 Plan. Options are exercisable into common stock.

All Company options were granted at exercise prices equal to the quoted market price of the Company’s common stock at the date of the grants. Options under these grants vest 25% per year over four years for employees and 100% after one year for consultants. Initial grants to directors vest 25% per year over four years and subsequent grants to directors vest 33 ¹/3% per year over three years. Options granted prior to May 1, 2007 expire on the tenth anniversary of the grant date. Options granted on or after May 1, 2007, expire on the seventh anniversary of the grant date. The total intrinsic value of options exercised was $ 839,022, $2,787,000, and $2,883,000 for the years ended May 31, 2009, May 31, 2008, and June 2, 2007, respectively.

3. Performance Share and Restricted Stock Unit Awards

The Company grants restricted stock units and performance share awards to certain employees under the 2004 Plan. The performance criteria is established by the compensation committee for vesting of the performance share awards and may include factors such as the achievement of certain sales, operating income and earnings per share (“EPS”) goals. Performance share awards are subject to additional conditions, including the recipient’s continued employment with the Company. The restricted stock unit awards vest in equal annual installments over the term of the grants. Unvested restricted stock unit awards will be forfeited if the recipient ceases to be employed by the Company, competes with the business of the Company, or otherwise engages in activities detrimental to the Company’s business before such date. The performance share awards and restricted stock units settle in shares of the Company’s common stock on a one-for-one basis.

The Company values performance share and restricted stock unit awards based on the closing trading value of the Company’s shares on the date of grant. The Company recognizes the compensation cost related to its non-vested stock awards ratably over the requisite service period, or over the performance period when performance award metrics are expected to be achieved, which is consistent with the treatment prior to the adoption of SFAS 123(R). Under APB 25, the performance share and restricted stock unit awards were accrued as vested and recorded in accrued liabilities. During the year ended June 2, 2007, the vested performance shares were issued and the liability for the restricted stock unit awards was reclassified to additional paid-in capital as required by SFAS 123(R).

5. Employee Stock Purchase Plan

The Employee Stock Purchase Plan (the “Stock Purchase Plan”) provides a means by which employees of the Company (the “participants”) are given an opportunity to purchase common stock of the Company through payroll deductions. The maximum number of shares to be offered under the Stock Purchase Plan is 400,000 shares of the Company’s common stock, subject to any increase authorized by the Board of Directors. Shares are offered through two purchase periods, each with duration of approximately 6 months, commencing on the first business day of the first and third fiscal quarters. An employee is eligible to participate in an offering period if, on the first day of an offering period, he or she has been employed in a full-time capacity for at least six months, with a customary working schedule of 20 or more hours per week and more than five months in a calendar year. Employees who own stock possessing 5% or more of the total combined voting power or value of all classes of the Company’s stock are not eligible to participate in the Stock Purchase Plan. The purchase price of the shares of common stock acquired on each purchase date will be the lower of (i) 85% of the fair market value of a share of common stock on the first day of the offering period or (ii) 85% of the fair market value of a share of common stock on the last day of the purchase period, subject to adjustments made by the Board of Directors. The Stock Purchase Plan is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code.

The Company uses the Black-Scholes option-pricing model to calculate the purchase date fair value of the shares issued under the Stock Purchase Plan and recognizes expense related to shares purchased ratably over the offering period.

Litigation Matters

AngioDynamics v. Vascular Solutions

On July 29, 2009, the Company filed a complaint in the United States District Court for the District of Delaware against Vascular Solutions, Inc. (NASDAQ: VASC). The complaint alleges that Vascular Solutions’ Vari-Lase Bright-Tip fiber product line infringes on claims of two of the Company’s patents, US 7,273,478 and US 7,559,329. These patents relate to methods of treating varicose veins using endovenous laser treatments.

Diomed v. AngioDynamics

On January 6, 2004, Diomed filed an action against the Company entitledDiomed, Inc. v.AngioDynamics, Inc., et al., civil action no. 04 10019 RGS in the U.S. District Court for the District of Massachusetts. Diomed’s complaint alleged that the Company infringed on Diomed’s U.S. patent no. 6,398,777 by selling a kit for the treatment of varicose veins (now called the “VenaCure Procedure Kit”) and two diode laser systems (the Precision 980 Laser and the Precision 810 Laser), and by conducting a training program for physicians in the use of the VenaCure Procedure Kit. The complaint alleged that the Company’s actions have caused Diomed to suffer substantial damages.

On March 28, 2007, the jury in the proceeding returned a verdict in favor of Diomed and awarded compensatory monetary damages in the amount of $8.36 million. The jury concluded, however, that there was no willful infringement by the Company. On May 22, 2007, the judge for the Federal District Court in Boston denied the Company’s motion to overturn the verdict and increased the judgment for compensatory damages by $1.35 million, to $9.71 million, to cover pretrial interest and post-verdict sales of the infringing products. The Company disputed the infringement verdict on multiple grounds and on June 20, 2007, filed an appeal in the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. The judgment also required the Company to pay interest to Diomed at an annual rate of approximately 5% of the damage award for the period of time between the verdict and actual payment of the award. As a result the Company accrued approximately $10.2 million, including interest. On July 2, 2007, the judge for the Federal District in Boston, Massachusetts, issued an injunction prohibiting the Company from selling its original bare fiber VenaCure product.

On March 14, 2008, Diomed commenced Chapter 11 bankruptcy proceedings. On April 2, 2008, the Company entered into a settlement with Diomed for the purpose of resolving the alleged patent infringement and paid $7.0 million in the fourth quarter of 2008. As a result of the settlement, in the third quarter of fiscal 2008 the Company reduced its litigation provision and recorded a gain of approximately $3.2 million pretax.

Until April 2007, the Company purchased the lasers and laser fibers for its laser systems from biolitec under a supply agreement. In 2006, biolitec advised the Company that based on Diomed’s refinement of its claims in the Diomed action, biolitec believed such claims were not within biolitec’s indemnification obligations under the supply agreement. The Company advised biolitec that it disagreed with biolitec’s position and that the Company expected biolitec to continue to honor its indemnification obligations.

On January 2, 2008, the Company commenced an action in the United States District Court for the Northern District of New York entitledAngioDynamics, Inc. v. biolitec, Inc. in which it is seeking, in part, judgment against biolitec for indemnification of defense costs incurred in the Diomed action and the VNUS action described below. Biolitec has filed counter-claims against us seeking reimbursement of approximately $1.6 million in alleged past defense costs paid by biolitec in one of the settled cases.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2009 and May 31, 2008

The Company will continue to vigorously enforce its rights under the supply agreement with biolitec. However, in the event it is ultimately determined that the claims asserted in the Diomed action and the VNUS action are not within biolitec’s indemnification obligations under the biolitec supply agreement, the Company may be required to reimburse biolitec for the costs and expenses of defending the Diomed action.

VNUS Medical Technologies v. Diomed, Vascular Solutions, and AngioDynamics

On October 4, 2005, VNUS Medical Technologies, Inc. (“VNUS”) filed an action against the Company and others (collectively, the “Defendants”) entitled VNUS Medical Technologies, Inc. v. Diomed Holdings, Inc., Diomed Inc., AngioDynamics, Inc., and Vascular Solutions, Inc. , case no. C05-2972 MMC, filed in the U.S. District Court for the Northern District of California. The complaint alleged that the Defendants infringed on VNUS’s U.S. patent nos. 6,258,084, 6,638,273, 6,752,803, and 6,769,433 by making, using, selling, offering to sell and/or instructing users how to use Diomed’s “EVLT” products, AngioDynamics’ “VenaCure” products, and Vascular Solutions’ “Vari-Lase” products. The complaint alleged the Defendants’ actions caused VNUS to suffer substantial damage. The complaint sought to prohibit the Defendants from continuing to market and sell these products and asks for compensatory and treble money damages, reasonable attorneys’ fees, costs and pre-judgment and post-judgment interest.

On June 3, 2008, the Company entered into an agreement with VNUS settling all patent litigation between it and VNUS. Under the terms of the settlement agreement, the Company paid VNUS approximately $6.8 million pretax. Accordingly, the Company recorded an accrual of $6.8 million as of May 31, 2008 which is included under the heading “Litigation provision” on the consolidated balance sheet. This payment was made in fiscal 2009. In addition, the Company agreed to pay a quarterly royalty on U.S. sales of its NeverTouch(TM), VenaCure(R) and Diomed products from June 1, 2008 until the expiration date of VNUS’ applicable patents. In exchange, VNUS granted the Company a non-exclusive and non-sublicenseable license to VNUS’ applicable patents for use in endovenous laser therapy.

The Company is party to legal actions that arise in the ordinary course of business. The Company believes that any liability resulting from any currently pending litigation will not, individually or in the aggregate, have a material adverse effect on the Company’s business, financial condition, results of operations, or cash flows.

Future Purchase Obligations

On October 17, 2005, the Company entered into a Supply and Distribution Rights Agreement (the “Agreement”) with Bioniche Pharma Group Limited (“Bioniche”). The Company was appointed the exclusive distributor in the Field, as defined in the Agreement, in the United States of Bioniche’s sodium tetradecyl sulfate product in concentrations of 1% and 3%, brand name “Sotradecol™” (“Product”). Sotradecol is used in sclerotherapy, a non-surgical procedure to remove varicose veins. The Agreement was amended during fiscal 2008 and expires on June 30, 2012. Future obligations under the agreement are as follows:

• three non-refundable milestone payments are due 30 days after achieving certain cumulative sales of Product. Payments of $500,000, $1,000,000 and $1,000,000 are due upon achieving cumulative sales of $10,000,000, $25,000,000 and $50,000,000, respectively. If the Company should lose any of its exclusive distribution rights under the Agreement, as amended, any milestone payments not yet made would not be required to be made. None of these sales milestones were achieved during the year ended May 31, 2009.

The Company has also entered into other commitments for future minimum inventory purchases related to several core products. Total future purchase obligations for fiscal years ending May 31 are as follows: $12.3 million in 2010, $9.1 million in 2011, $5.0 million in 2012, $4.8 million in 2013 and $2.1 million in 2014.

NOTE R–SEGMENTS

SEGMENT AND GEOGRAPHIC INFORMATION

Historically, the Company reported its results of operations as a single segment. Beginning with fiscal 2009, the Company has organized its business into three reportable segments: Peripheral Vascular, Access and Oncology/Surgery. The Peripheral Vascular segment is comprised of the venous, angiographic, PTA, drainage and thrombolytic product lines. The Access segment is comprised of the dialysis, port and PICC product lines. The Oncology/Surgery segment is comprised of the RFA, embolization, Habib and NanoKnife product lines.

Selected information by reportable segment is presented in the following tables (in thousands):

The results for fiscal years ended May 31, 2008 and June 2, 2007 have been presented to reflect these new reportable segments for net sales and gross profit. Operating income and total assets for the prior periods have not been disclosed as it was impracticable to do so.

In accordance with FAS No. 131, “Disclosures About Segments of an Enterprise and Related Information”, the internal organization that is used by management for making operating decisions and assessing performance is used as the source of the Company’s reportable segments. The Company’s chief operating decision maker evaluates performance based on the reportable segments and utilizes net sales, gross profit and operating income as primary profitability measures. The expenses related to certain shared and corporate activities are allocated to these segments on a percentage of total sales basis or operating expense basis as deemed appropriate.

Total sales for geographic areas are summarized below (in thousands):

	Year ended
	May 31, 2009		May 31, 2008		June 2, 2007
Net Sales by Geography
United States	$	173,406	$	150,643	$	105,154
International		21,648		15,857		7,073
Total	$	195,054	$	166,500	$	112,227

The Company markets its products internationally through a direct sales force and independent distributors. The international distributors may also distribute competitive products under certain circumstances. The international distributors also play an important role in the Company’s clinical testing outside of the United States. The loss of any international distributor would not have a material adverse effect on the Company’s business if a new distributor, sales representative or other suitable sales organization could not be found on a timely basis.
