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, NanoKnife Ablation Systems, 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 14 Plaza Drive, Latham,

New York 12110. Our phone number is (518) 795-1400.

on Form 10-K.

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

Company Reorganization

Prior to fiscal 2009, we reported our results of operations as a single segment. At the beginning of fiscal
2009, 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, 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.

3

Distribution Agreement Amendment

We sell the embolization product, LC Bead, pursuant to a Supply and Distribution Agreement with
Biocompatibles UK Limited that grants us exclusive distribution rights to the product in the United States. The
Agreement was entered into in 2006 and has been amended four times, most recently in March 2010 to extend
distribution rights until December 31, 2011.

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 was completed in the third quarter of fiscal 2009 and the former chief executive
officer has not had an operating role with us since 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 to prevent and treat acute kidney injury, in the emerging field of Targeted Renal Therapy.

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.

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 low energy direct current ablation technology
in the first human clinical trial for the treatment of soft tissue in April 2008.

(b) Narrative Description of Business

General

Prior to fiscal 2009, we reported our results of operations as a single segment. At the beginning of fiscal
2009, we organized our business into three reportable segments: Peripheral Vascular, Access and Oncology/
Surgery. The Peripheral Vascular segment is comprised of our venous, angiographic, PTA, drainage and
thrombolytic product lines. The Access segment is comprised of our dialysis, ports and PICC product lines. The
Oncology/Surgery segment is comprised of our 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’

4

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 established
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. The 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 vascular disease and cancerous tumors. Interventional oncology is a large and
growing area. In addition, in May 2008 we acquired the Nanoknife ablation system which is complementary to
our diverse offering of local oncology therapies, including market-leading RFA systems, Habib Sealer™
resection devices and LC Beads™ for tumor embolization. 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 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 internationally

through a combination of direct sales and distributor relationships. 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.

Products

Our product offerings fall under three product groupings, which are paralleled by our organizational

structure of three Strategic Business Units (e.g. reportable segments)—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;
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 and Micro Access product lines.

Venous Products

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 50 suffering from varicose veins, the market for this
treatment is large and growing.

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

Our VenaCure EVLT laser system 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

5

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 little-to no scarring and minimal post-operative pain.

With our VenaCure EVLT laser system, 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 featuring our NeverTouch® gold-tip
technology, an access sheath, access wires and needles. The procedure kits come in a variety of lengths and
configurations to accommodate varied patient anatomies.

Sotradecol® (sodium tetradecyl sulfate injection), a sclerosing drug approved by the FDA that we
introduced in November 2005 has been shown to be an effective treatment of small, uncomplicated varicose
veins of the lower extremities, that show simple dilation with competent valves. The benefit-to-risk ratio should
be considered in selected patients who are great surgical risks.

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 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.

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 angiographic catheter technology incorporates a soft, atraumatic tip
that is easily visualized under fluoroscopy.

• AngiOpticTM. The AngiOptic catheter line is distinguished from other catheters because the entire

instrument is highly visible under fluoroscopy.

• Accu-Vu®. The Accu-Vu angiographic catheter 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.

• MarinerTM. The Mariner catheter 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.

• AQUA Liner®. The AQUA Liner guidewire is a technologically advanced guidewire. It is used to

provide access to difficult-to-reach locations in interventional procedures requiring a highly lubricious
wire. The AQUA Liner guidewire incorporates proprietary advanced coating technology that allows
smooth frictionless navigation.

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.

6

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 balloon 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 balloon catheter 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.

Our line of drainage products, The Total Abscession® Family of Drainage Catheters, consists of our Total
Abscession General, Biliary, and Nephrostomy drainage catheters. These products feature our proprietary soft
shaft with Blue Silk™ finish for a more comfortable patient fit. The kink-resistant shaft recovers rapidly, even if
severely bent, knotted, or twisted. This is particularly beneficial when patients roll over and risk a potential
kinking of the catheter during sleep. The thermal molded tip allows for less buckling and kinking upon
insertion. Also important is that the shaft diameter equals the inner diameter of the catheter hub to maximize
flow. Our Total Abscession drainage catheters feature a tamper-resistant locking mechanism called the Vault®
which securely fixes the pigtail and prevents tampering or accidental removal. This locking mechanism helps to
prevent the drain from becoming unlocked during routine use, thus reducing a physician’s time by avoiding a
possible “redo” case, and increasing patient satisfaction by not having to repeat the procedure. The Total
Abscession catheter permits aspiration in the locked or unlocked position 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® Infusion Catheters and Uni*Fuse thrombolytic 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. 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.

7

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.

ACCESS

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

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

• DuraMax®. The DuraMax catheter is a stepped-tip catheter designed to improve ease of use, dialysis

efficiency and overall patient outcomes.

•

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

• Evenmore®. The Evenmore chronic dialysis catheter is a low-profile, end-hole catheter designed to
provide 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-FlowTM. 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®. The LifeJet 16-French chronic dialysis catheter features a unique Circle C® lumen design and
the largest internal diameter available. This is designed to facilitate high flow rates while keeping
arterial and venous pressures low.

• Centros®. Centros with Curved Tip™ catheter technology is the next generation, self-centering, split-tip
dialysis catheter. The highly innovative Centros catheter design features preformed curved tips, which
automatically center the catheter ports within the middle of the vessel to maintain optimal blood flow
and recirculation rates, increasing catheter life and enhancing overall catheter performance by enabling
the potential to reduce clot formation and sheathing.

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.

8

PICC Products

Our PICC products include:

• Morpheus® CT PICC and 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. 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.

• Morpheus® Smart PICC. The Morpheus Triple Lumen Smart PICC, the next evolution of the
AngioDynamics’ Morpheus CT PICC line, gives practitioners the increased flexibility to both
administer medications and perform power injections of contrast media for CT imaging using one
PICC line. The Morpheus Smart PICC features Smart Taper™ technology to improve blood flow and
reduce the risk of thrombosis while reducing leakage around the insertion site.

Port Products

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:

• Vortex®. Our Vortex port technology line of ports is a clear-flow port technology that, we believe,

revolutionized port design. With its rounded chamber, the Vortex port is designed to have no sludge-
harboring corners or dead spaces. 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.

•

•

SmartPort®. The Smart Port power-injectable port with Vortex technology 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. Our Smart Port is now available in mini and low-profiles to accommodate more
patient anatomies.

LifeGuardTM. The LifeGuard Safety Infusion Set and The LifeGuard Vision are used to infuse our ports
and complement our port and vascular access catheters. The needles’ low profile design is intended to
allow clinicians to easily dress the site.

Our central venous catheter products include:

• Neostar®. Our 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

ONCOLOGY/SURGERY

Our Oncology/Surgery Strategic Business Unit includes our Radiofrequency Ablation (RFA), Embolization

and NanoKnife® 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® Xli-
enhanced 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.

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, which is used in minimally invasive laparascopic surgery (MILS) procedures
in surgical specialties such as: Hepato-Biliary, GI, Surgical Oncology, Transplant Surgery and Urology (Partial
Nephrectomy Resections). It is clinically indicated to assist in coagulation of tissue during intraoperative and
laparoscopic procedures.

Embolization Products

LC Beads™ embolization products are compressible, visibly-tinted N-fil Hydrogel microspheres supplied in

convenient pre-prepared single vials. Embolic material is injected into selected vessels to block the blood flow
feeding the tumor or malformation, causing it to shrink over time. We purchase LC Beads from Biocompatibles
UK Limited pursuant to a Supply and Distribution Agreement that was entered into in 2006 and terminates on
December 31, 2011 unless extended prior thereto.

NanoKnife® Ablation System Products

The NanoKnife® Ablation System is for the surgical ablation of soft tissue. The NanoKnife Ablation System

utilizes low energy direct current 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, NanoKnife Ablation System does not achieve tissue ablation using thermal
energy—allowing targeted tissue elimination while critical structures, such as ducts and blood vessels remain
viable.

The Nanoknife Ablation 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 suggests that the NanoKnife

Ablation System has the following characteristics:

•

Spares vital structures. Because NanoKnife Ablation System does not use thermal energy to ablate
tissue, vital structures such as vasculature and ducts remain intact. NanoKnife Ablation System enables
ablation treatment at or near critical structures, resulting in selective tissue damage.

• Eliminates heat sink issues seen with other ablation modalities. NanoKnife Ablation System 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 ablation. A Nanoknife 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 2010, 2009 and 2008, our research and development (“R&D”) expenditures were
$19.3 million, $17.9 million and $14.4 million, respectively, and constituted 8.9%, 9.2% and 8.7%, respectively,
of net sales. R&D activities include research, product development, intellectual property and regulatory affairs.
We expect that our R&D expenditures will be approximately 9.5% of net sales in fiscal 2011 primarily due to
investment in NanoKnife Ablation System 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.

11

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: Boston Scientific Corporation; Cook Medical; Navilyst Medical; Cordis
Corporation, a subsidiary of Johnson & Johnson, Inc.; C.R. Bard; Medical Components, Inc. or Medcomp;
Arrow International, a subsidiary of TeleFlex Medical; Smith’s Medical, a subsidiary of Smiths Group plc;
Vascular Solutions; Covidien subsidiaries (Kendall, VNUS, EV3) and Merit Medical (Biosphere Medical).

Medcomp supplies us with most of our dialysis catheters and 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
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.

Backlog

Historically, we ship 95% of products 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

12

feet located in Manchester, Georgia. We lease a manufacturing facility of approximately 10,000 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, 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 available from several supply

sources. We also purchase finished products from third parties. One supplier, Biocompatibles UK Limited,
supplies our LC Beads ™ embolization products that accounted for approximately 10% of our net sales for fiscal
2010. Another supplier, Medcomp, currently supplies most of our dialysis catheters. Medcomp products
accounted for approximately 8% of our net sales for fiscal 2010. To date, we have been able to obtain adequate
supplies of all product and components in a timely manner from existing sources.

In fiscal 2010, 69% 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 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, 2010, we owned 167 U.S. utility patents, 118 pending U.S. utility applications, and 243
foreign issued and pending utility patents. We also own 50 U.S. registered trademarks and 39 common law
trademarks. There are currently 30 registered international trademarks and 15 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, 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

13

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.

See Item 3 of this report for additional details on litigation regarding proprietary technology.

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

14

“substantially equivalent” in intended use and in safety and effectiveness to a “predicate device,” which is a
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

15

manufacturers are required to register their facilities and list their products with the FDA and certain state
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.

International 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 International 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.

International 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.

16

Third-Party Reimbursement

United States

Our products are used in medical procedures generally covered by government or private health plans.

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.

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 in order 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.

International

Our success in International 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 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.

17

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, 2010, we had 681 full-time employees, including 343 in manufacturing; 83 in research,

product development and regulatory approval/quality assurance; 196 in sales and marketing; and 59 in
administration. None of our employees are represented by a labor union, and we have never experienced a work
stoppage.

18

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. Our
primary device competitors include: Boston Scientific Corporation; Cook Medical; Navilyst Medical; Cordis
Corporation, a subsidiary of Johnson & Johnson, Inc.; C.R. Bard; Medical Components, Inc. or Medcomp;
Arrow International, a subsidiary of TeleFlex Medical; Smith’s Medical, a subsidiary of Smiths Group plc;
Vascular Solutions; Covidien subsidiaries (Kendall, VNUS, EV3) and Merit Medical (Biosphere Medical). Many
of our competitors have substantially greater:

•

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

19

•

•

•

•

•

•

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 NanoKnife Ablation 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 NanoKnife Ablation may adversely affect our business, financial
condition and results of operations.

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

We currently have FDA 510(k) clearance to market NanoKnife Ablation 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 NanoKnife Ablation 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;

20

•

•

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.

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 AngioDynamics’ patents, US 7,273,478 and US
7,559,329. These patents relate to methods of treating varicose veins using endovenous laser
treatments. Vascular Solutions has filed with the U.S. Patent & Trademark Offices, or PTO, requests for inter
partes reexamination of the ‘478 and ‘329 patents. The PTO has initiated reexamination of these patents. No final
ruling on the merits has been made at this time. Vascular Solutions has denied the allegations of infringement
and has counterclaimed for a declaratory judgment that it does not infringe, that the patents are invalid and that
the patents are unenforceable as a result of alleged inequitable conduct. If Vascular Solutions is ultimately
successful in convincing the PTO or a court that our patents are invalid, we could lose the ability to assert these
patents against other third parties.

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

21

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
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 2010,
approximately 31% of our product sales were derived from sales of products manufactured for us by third parties.
One supplier, Biocompatibles UK Limited, supplies our LC Beads ™ embolization products that accounted for
approximately 10% of our net sales for fiscal 2010. Another supplier, Medcomp, currently supplies most of our
dialysis catheters. Medcomp products accounted for approximately 8% of our net sales for fiscal 2010. 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.

Failure to reach an agreement to extend our distribution rights to LC Bead could have an adverse effect on
our results of operations.

We sell the embolization product, LC Bead, pursuant to a Supply and Distribution Agreement with
Biocompatibles UK Limited that grants us exclusive distribution rights to the product in the United States. The
Agreement was entered into in April 2006 and was amended in October 2007, June 2008, March 2009 and March
2010. Under the Agreement, we are required to purchase certain minimum levels of product from
Biocompatibles. The March 2010 Amendment specifies distribution rights until December 31, 2011. During our

22

fiscal 2010, sales of LC Bead accounted for approximately 10% of our net sales. Failure to extend our
distribution rights to LC Bead after December 31, 2011 could have an adverse effect on our results of operations.

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.

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 recent laws 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.

23

On March 23, 2010, the Patient Protection and Affordable Care Act was signed into law and on March 30,

2010, the Health Care and Education Reconciliation Act of 2010 was signed into law. Together, the two
measures make the most sweeping and fundamental changes to the U.S. health care system since the creation of
Medicare and Medicaid. The Health Care Reform laws include a large number of health-related provisions to
take effect over the next four years, including expanding Medicaid eligibility, requiring most individuals to have
health insurance, establishing new regulations on health plans, establishing health insurance exchanges, requiring
manufacturers to report payments or other transfers of value made to physicians and teaching hospitals, and
modifying certain payment systems to encourage more cost-effective care and a reduction of inefficiencies and
waste, including through new tools to address fraud and abuse. Effective in 2013, there will be a 2.3% excise tax
on the sale of certain medical devices.

In addition, various healthcare reform proposals have also emerged at the state level. We cannot predict the

exact effect newly enacted laws or any future legislation or regulation will have on us. However, the
implementation of new legislation and regulation may lower reimbursements for our products, reduce medical
procedure volumes and adversely affect our business, possibly materially. In addition, the enacted excise tax may
materially and adversely affect our operating expenses and results of operations.

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.

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

24

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 $10,000,000 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.
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
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.

25

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 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.

26

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
products would cause serious adverse health consequences. A government mandated, 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

27

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.

If our employees or agents violate the U.S. Foreign Corrupt Practices Act or anti-bribery laws in other
jurisdictions, we may incur fines or penalties, or experience other adverse consequences.

We are subject to the U.S. Foreign Corrupt Practices Act, or FCPA, and similar anti-bribery laws in
international jurisdictions which generally prohibit companies and their intermediaries from making improper
payments to non-U.S. officials for the purpose of obtaining or retaining business. Because of the predominance
of government-sponsored healthcare systems around the world, many of our customer relationships outside of the
United States are with governmental entities and are therefore subject to such anti-bribery laws. Our sales to
customers and distributors outside of the United States have been increasing and we expect them to continue to
increase in the future. If our employees or agents violate the provisions of the FCPA or other anti-bribery laws,
we may incur fines or penalties, we may be unable to market our products in other countries or we may
experience other adverse consequences which could have a material adverse effect on our operating results or
financial condition.

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,

and Cambridge, England. 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 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, Divisions and Disease State groups could impact our
ability to meet our customers’ demands, which could cause future sales to suffer.

28

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;

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.

29

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.

Our goodwill and intangible assets are subject to potential impairment.

A significant portion of our assets consists of goodwill and intangible assets, the carrying value of which

may be reduced if we determine that those assets are impaired. At May 31, 2010, goodwill and intangible assets
represented approximately $220 million, or approximately 52% of our total assets.

All of our intangible assets have determinable useful lives and are amortized over their useful lives on either

a straight-line basis or over the expected period of benefit or as revenues are earned from the sales of the related
products. The underlying assumptions regarding the estimated useful lives of these intangible assets are reviewed
quarterly and more often if an event or circumstance occurs making it likely that the carrying value of the assets
may not be recoverable and are adjusted through accelerated amortization if necessary.

We review our three reporting segments for potential goodwill impairment in the third fiscal quarter of each

year as part of our annual goodwill impairment testing, and more often if an event or circumstance occurs
making it likely that impairment exists. We conduct impairment testing based on our current business strategy in
light of present industry and economic conditions, as well as future expectations. The annual goodwill
impairment review performed in December 2009 indicated no goodwill impairments.

If actual results differ from the assumptions and estimates used in the goodwill and intangible asset
calculations, we could incur future (unanticipated) impairment or amortization charges, which could negatively
impact our results of operations.

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, for a ten year period plus 2 five year
renewal options, a 52,500 square foot office building in Latham, New York to house our corporate headquarters
and certain business operations. We commenced occupancy of the facility in March 2010. The lease
commencement date was March 1, 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. Subsequent to May 31, 2010, this
lease was extended through April 30, 2013. We lease 14,500 square feet of office and research and development
space in Fremont, California. The lease expires in May 2012. Finally, we lease an office and manufacturing
facility of approximately 10,000 square feet in the United Kingdom. The lease expires in October 2013.

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’
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. Vascular Solutions has filed with the U.S. Patent & Trademark Offices, or PTO, requests for inter
partes reexamination of the ‘478 and ‘329 patents. The PTO has initiated reexamination of these patents. No final
ruling on the merits has been made at this time. Vascular Solutions has denied the allegations of infringement
and has counterclaimed for a declaratory judgment that it does not infringe, that the patents are invalid and that
the patents are unenforceable as a result of alleged inequitable conduct. Vascular Solutions does not seek
damages but does seek attorney’s fees and costs of an unspecified amount should it prevail on its counterclaims
and defenses. AngioDynamics intends to vigorously pursue its claims and defend against Vascular Solutions’
counterclaims. The case has been transferred to the United States District Court for the District of Minnesota, and
is currently in the discovery stage and no ruling has been made on the merits of any claim, defense, or
counterclaim.

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 judgment against biolitec for
defense and indemnification costs we incurred in the Diomed action and the VNUS action described elsewhere in

31

this report. 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.

On October 26, 2009, we commenced an action in the United States District Court for the District of
Massachusetts entitled AngioDynamics, Inc. v. biolitec AG, et al. In this action, we are asserting claims of
tortious interference with contract, piercing the corporate veil, declaratory judgment, fraudulent transfer, and
unfair or deceptive business practices against biolitec, Inc., biolitec AG (the corporate parent of biolitec, Inc.), a
shareholder of biolitec AG, and an executive of biolitec AG. The defendants have not yet answered, and no
counterclaims have been asserted against us to date.

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
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. This payment was made in fiscal 2009.
In addition, we agreed to pay a quarterly royalty on our U.S. sales of our Nevertouch® , 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-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.

$0.15 per basic and diluted share for fiscal 2009, $3.1 million or $0.13 per basic and diluted share for fiscal
2008, and $2.4 million, or $0.13 per basic and diluted share for fiscal 2007. See Notes A and O to the
Consolidated Financial Statements for additional information.

(c)

(d)

In January 2007, we acquired RITA Medical Systems, Inc. for approximately $244 million. In connection
with the acquisition, we incurred an in-process R&D charge of $12.1 million, or approximately $0.66 per
basic and diluted share.

In fiscal 2007, we accrued $9.7 million for the Diomed patent infringement matter. In fiscal 2008, we
accrued $6.8 million for the settlement of the VNUS patent infringement and reversed $3.2 million of the
Diomed patent infringement accrual as a result of the settlement of the matter.

(e) To conform with the fiscal 2010 presentation, fiscal 2009 results include reclassifications made to include
strategic business unit management in marketing costs. The reclassifications resulted in an increase in
marketing costs and a decrease in general and administrative costs of $1,012,000 in fiscal 2009.

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 and embolization products for treating benign and malignant
tumors. In addition, we provide our NanoKnife system for the ablation of soft tissue. 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.

Prior to fiscal 2009, we reported our results of operations as a single segment. At the beginning of fiscal
2009, we organized our business into three reportable segments: Peripheral Vascular, Access and Oncology/
Surgery. The Peripheral Vascular segment is comprised of our venous, angiographic, PTA, drainage and
thrombolytic product lines. The Access segment is comprised of our dialysis, port and PICC product lines. The
Oncology/Surgery segment is comprised of our 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:

100%

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, 2010, our sales
organization numbered 132 in the U.S. and 20 outside the U.S. For fiscal years 2010, 2009 and 2008, net sales in
non-U.S markets were 10.7%, 11.1% and 9.5%, respectively. The increase in our net sales outside the U.S. from
2008 to 2009 is primarily as a result of the Diomed acquisition completed in June 2008.

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 2010, 2009 and 2008, our research and development (“R&D”) expenditures were
$19.3 million, $17.9 million and $14.4 million, respectively, and constituted 8.9%, 9.2% and 8.7%, respectively,
of net sales. R&D activities include research, product development, intellectual property, and regulatory and

39

clinical affairs. R&D expenditures related to the NanoKnife system projects totaled $7.3 million in 2010 and $6.9
million in 2009, or 3% and 4% of net sales, respectively. We expect that our R&D expenditures will be
approximately 9.5% of net sales in fiscal 2011 primarily due to investment in NanoKnife 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 ablation technology which uses
low energy direct current (“LEDC”) electrical pulses which will be complementary to RITA’s diverse offering of
local oncology therapies, including its market-leading RFA systems, Habib SealerTM resection devices and LC
Beads TM for tumor embolization. We are in the process of commercializing the LEDC 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 2010, approximately 31% of our product sales were derived from products manufactured for us by

third parties, as compared with 35% for fiscal 2009 and 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 to house our corporate
headquarters and certain business operations. We commenced occupancy of the facility in 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

Distribution Agreement Amendment

We sell the embolization product, LC Bead, pursuant to a Supply and Distribution Agreement with
Biocompatibles UK Limited that grants us exclusive distribution rights to the product in the United States. The
Agreement was entered into in 2006 and has been amended four times, most recently in March 2010 to extend
distribution rights until December 31, 2011.

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

40

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 has
been accounted for as a purchase and, accordingly, we have included the results of operations in the financial
statements effective January 12, 2009. 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 has been accounted for as a purchase and, accordingly, we have included the results of
operations in the financial statements effective June 17, 2008. 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.

Company Reorganization

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

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 low energy direct current ablation technology
in the first human clinical trial for the treatment of soft tissue in April 2008.

41

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,
$5.0 million in November 2008 and $5.0 million 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 low energy direct current to achieve tissue ablation by inducing
irreversible electroporation. 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. Substantially all of the purchase price was recorded as product technology and is being
amortized over a 15 year useful life. We have 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.

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.

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.

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

authoritative guidance on 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

42

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.

We have chosen to early adopt, effective with the third quarter of fiscal 2010, updated authoritative

guidance for revenue recognition relating to the accounting treatment for revenue arrangements that involve more
than one deliverable or unit of accounting. At the same time, we also adopted the updated guidance relating to
certain revenue arrangements that include software elements. Neither of these had a material effect on our
consolidated financial statements.

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. We perform ongoing credit
evaluations of our customers and adjust credit limits based upon payment history and the customer’s current
creditworthiness, 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 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 2010, 2009 and 2008, 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, 2010, our valuation allowance and net
deferred tax asset were approximately $1.2 million and $7.8 million, respectively. The deferred tax asset includes
$56.6 million of Federal net operating loss carryforwards and $26.8 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 $13.6 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 $3 million of taxable income in each year over the next sixteen 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 sheets.

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.

43

Our Federal net operating loss carryforwards as of May 31, 2010 after considering IRC Section 382
limitations are $43.0 million. The expiration of the Federal net operating loss carryforwards are as follows: $0.3
million in 2011, $26.6 million between 2017 and 2021 and $16.1 million between 2022 and 2026.

Our state net operating loss carryforwards as of May 31, 2010 after considering remaining IRC Section 382

limitations are $15.0 million which expire in various years from 2011 to 2026.

In July 2006, FASB issued authoritative guidance on “Accounting for Uncertainty in Income Taxes”, which

clarifies the accounting for uncertainty in tax positions. This guidance seeks to reduce the diversity in practice
associated with certain aspects of the recognition and measurement related to accounting for income taxes. This
guidance 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 guidance was
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 guidance on
June 3, 2007. There was no cumulative effect of the adopting the guidance. Upon adoption, the liability for
unrecognized tax benefits was zero.

During the twelve months ended May 31, 2010, 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 the guidance
on tax uncertainties mentioned above. Accrued interest and penalties recognized in the consolidated balance
sheet were $0 as of May 31, 2010 and May 31, 2009.

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 2007 through 2010 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 flows.

We do 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, 2010, May 31, 2009 and May 31, 2008, our reserve for excess and obsolete
inventory was $2,201,000, $3,074,000 and $3,694,000, 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 result
in an impairment and/or significantly affect depreciation expense on a prospective basis.

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.

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 as opposed to a single segment in prior periods. Our 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, 2009. Our assessment of goodwill
impairment indicated that the fair value of each of our 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 26%, 6% and 16%, 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 8% as of December 31, 2009.

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.

To determine fair value, we utilized two market-based approaches and an income approach. Under the
market-based approaches, we utilized information regarding our own 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 2011, followed by a recovery thereafter.
In addition, we applied gross margin assumptions consistent with our historical trends at various revenue levels
and used an EBITDA exit multiple of 6.0, 6.0 and 7.0 to calculate the terminal value of the Peripheral Vascular,
Access and Oncology/Surgery reporting units, respectively, compared to an EBITDA exit multiple of 6.5, 7.0
and 8.0, respectively, used in the prior year. In addition, we used a discount rate of 21%, 15% and 18% to
calculate the fair value of our Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively.
These discount rates vary from the rates of 19%, 16% and 19%, respectively, used in the prior year.

45

We 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. Even though we determined that
there was no goodwill impairment as of December 31, 2009, 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, 2010. 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. 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.

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 2010 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.

Stock-based compensation

We recognize 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 recognize compensation expense for our stock awards on a straight-line basis
over the requisite service periods of the awards, which is generally the vesting period.

For 2010, stock based compensation was $4.9 million pre-tax ($3.1 million after tax, or $0.13 per diluted

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

Under the provisions of the guidance adopted, we expect to recognize the following future expense for

awards granted prior to May 31, 2010:

Stock options . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Unrecognized compensation cost for stock options is presented net of 5.6% assumed annual forfeitures.

The amount of stock-based compensation recognized is based on the value of the portion of awards that are

ultimately expected to vest. Guidance 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 94.4% of our options
will vest annually, and we have therefore applied a 5.6% annual forfeiture rate in determining the stock-based

46

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, 2010, May 31, 2009 and May 31, 2008, we used the Black-Scholes
option-pricing model (“Black-Scholes”) as our method of valuation 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 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 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.

To conform with the fiscal 2010 presentation, fiscal 2009 results above include reclassifications made to
include strategic business unit management in marketing costs. The reclassifications resulted in an increase in
marketing costs and a decrease in general and administrative costs of 0.5% in fiscal 2009.

In July 2009, we entered into an agreement to lease, for a ten year period plus 2 five year renewal options, a

52,500 square foot office building in Latham, New York to house our corporate headquarters and certain
business operations. We commenced occupancy of the facility in March 2010. The lease provides for annual rent
of $857,321 for the first five years and $943,054 for the next five years, plus the payment of customary building
operating expenses. The lease commencement date was March 1, 2010.

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 was completed in the third quarter of fiscal 2009 and the former chief executive
officer has not had an operating role with us 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. The accrued liability for the
CEO transition on the Balance Sheet was $1 million at May 31, 2009 and $0 on May 31, 2010. 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.

For 2010, 2009 and 2008, 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 $7.6
million, $6.7 million and $7.3 million for the years ended May 31, 2010, May 31, 2009 and May 31, 2008,
respectively. Under purchase accounting rules, we are unable to use acquired NOLs to offset our provision for
income taxes in the statements of operations.

Fiscal years ended May 31, 2010 and May 31, 2009

Net sales. Net sales are derived from the sale of our products and related freight charges, less discounts and

returns. Net sales for fiscal 2010 increased by 11%, or $20.9 million, to $216.0 million from $195.1 million in
fiscal 2009. The growth in net sales was primarily attributable to increased unit sales of LC Beads, VenaCure
EVLT procedure kits, Nanoknife generators and probes, Benephit renal infusion products and RF electrodes,
partially offset by a decrease in unit sales of infusion sets.

From a segment perspective, Peripheral Vascular sales increased 10% to $92.1 million from $83.5 million.

This increase was driven primarily by increased sales of VenaCure EVLT procedure kits and Benephit renal
infusion products. Access sales were $67.0 million, a slight increase from $66.8 million primarily attributable to
increased unit sales of dialysis, PICC and port products partially offset by decreased unit sales of infusion sets
and a 5% decline in average selling prices of Access products. Oncology/Surgery sales were $56.9 million, an
increase of 27% over the prior year results of $44.8 million primarily due to increased unit sales of our LC
Beads, Nanoknife generators and probes and RF electrodes. Nanoknife sales totaled $2.5 million in fiscal 2010.

From a geographical perspective, US sales increased $19.5 million or 11% in fiscal 2010 to $192.9 million

from $173.4 million a year ago. This increase is primarily attributable to increased unit sales of LC Beads,
Venacure EVLT procedure kits, Benephit renal infusion products and Nanoknife generators partially offset by a
decrease in unit sales of infusion sets. International sales were $23.1 million in fiscal 2010, up 7% from $21.7
million in fiscal 2009. Increased unit sales of RF electrodes, RF generators and other RF devices comprised the
majority of this increase.

48

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 decreased to 58.8% for fiscal 2010 from 61.6% for fiscal 2009. The decrease in gross
profit percentage was primarily due to lower average selling prices for Access and Peripheral Vascular products
and higher material costs for certain Access products partially offset by higher average selling prices for
Oncology/Surgery products.

Research and development expenses. Research and development (“R&D”) expenses include costs to
develop new products, enhance existing products, validate new and enhanced products, manage clinical and
regulatory affairs and our intellectual property. R&D expenses increased by $1.4 million, or 8%, to $19.3 million
in fiscal 2010. The increase is primarily due to the cost of development of new Access products and increased
spending on clinical activities. As a percentage of net sales, R&D expenses were 8.9% for fiscal 2010, compared
with 9.2% for the prior year period. $7.3 million was spent on NanoKnife R&D activities in fiscal 2010. At
May 31, 2010, we employed 83 people in R&D activities compared with 81 people at the end of fiscal 2009.

Sales and marketing expenses. Sales and marketing (“S&M”) expenses consist primarily of salaries,
commissions, travel and related business expenses, attendance at medical society meetings, product promotions
and samples. S&M expenses increased $3.1 million or 5% to $60.9 million in fiscal 2010. This increase is
primarily due to increased marketing activities for the Venacure EVLT and Benephit renal infusion products and
NanoKnife marketing activities. These increased costs were partially offset by lower spending on marketing
programs and trade show activities. As a percentage of net sales, S&M expenses were 28.2% for fiscal 2010,
compared with 29.6% for fiscal 2009. $1.9 million was spent on NanoKnife sales and marketing activities in
fiscal 2010. At May 31, 2010, we employed 196 people in sales and marketing activities compared with 201
people a year ago.

General and administrative expenses. General and administrative (“G&A”) expenses includes the cost of

executive management, finance, accounting, legal, human resources and information technology and the
administrative and professional costs associated with those activities. G&A expenses decreased $2.7 million, or
14%, to $16.4 million in fiscal 2010 due to inclusion in the prior year period of $3.7 million of CEO transition
costs and the write off of architectural, planning and design costs associated with a cancelled project to build
office space in Queensbury, New York, partially offset by increased personnel and other infrastructure costs to
support our growth. Exclusive of these costs in the prior year, G&A expenses decreased to 7.6% of net sales in
fiscal 2010 as compared to 7.9% in the prior year. This improvement was gained by aggressive cost management.
As of May 31, 2010, we employed 59 people in general and administrative activities compared with 56 people a
year ago.

Amortization of intangibles. Amortization of intangibles increased $337,000 in fiscal 2010 compared with

the prior year, primarily due to amortization of Peripheral Vascular intangibles. Amortization of NanoKnife
intangibles was $1.7 million in fiscal 2010.

Operating income. Operating income was $20.9 million and $16.1 million for fiscal 2010 and 2009,

respectively. As a percentage of sales, operating income for 2010 was 9.7% compared with 8.3% in the prior year
or 10.2%, exclusive of the CEO transition costs.

Other income (expenses). Other income and expenses for fiscal 2010 increased to expense of $1.3 million

compared with expense of $1.0 million in the prior year. This increase is primarily attributable to reduced interest
income as a result of lower investment rates on cash and marketable securities, partially offset by reduced foreign
exchange losses and reduced losses on an interest rate swap.

Income taxes. Our provision for income taxes increased $2.1 million in fiscal 2010, to $7.3 million from

$5.2 million in fiscal 2009. Our effective tax rate was 37.2% in fiscal 2010 and 34.5% in fiscal 2009. The
reinstatement of the previously expired R&D tax credit reduced our fiscal 2009 effective tax rate by 1.4% which

49

was additive to the 1.7% reduction related to fiscal 2009 R&D credits, amounting to a total effective rate
reduction of 3.1% in fiscal 2009. This credit expired again on December 31, 2009 and to date has not been
renewed. Accordingly fiscal year 2010 includes the utilization of this credit only until its expiration date which
amounted to a reduction in our 2010 effective rate of 1.1%. Additionally during 2010 our non-U.S. pre-tax loss
negatively impacted our effective tax rate by 1.1% compared to fiscal year 2009 during which our non-U.S.
pre-tax income created an effective tax rate benefit of 1.8%. 2010 federal income tax payments were reduced by
$7.6 million through the utilization of net operating losses acquired as a result of the RITA acquisition compared
with $6.7 million in 2009.

Net income. For fiscal 2010, we reported net income of $12.3 million, an increase of $2.4 million from net

income of $9.9 million in fiscal 2009.

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 segment 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. NanoKnife products 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 manage clinical and
regulatory affairs and 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
NanoKnife development and commercialization activities. R&D expenditures for the NanoKnife 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.

50

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 $11.7 million or 25% to $57.8 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
NanoKnife sales activities. Marketing expenses increased approximately $5.1 million, or 50%, over the prior
year period, primarily due to NanoKnife 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 29.6% for fiscal 2009, compared with 27.7% for the prior year period. $1.0 million was spent on NanoKnife
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 $3.7 million, or 24%, to
$19.1 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. G&A expenses were 9.8% 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.

During the past three years, we have financed our operations primarily through cash flow from operations.

At May 31, 2010, $100.1 million or 24% of our assets consisted of cash, cash equivalents and marketable
securities. Marketable securities are comprised of U.S. government issued or guaranteed securities, corporate
bonds and auction-rate securities. Our current ratio was 6.6 to 1, with net working capital of $145.3 million at
May 31, 2010, compared with a current ratio of 5.0 to 1, with net working capital of $118.9 million, at May 31,
2009. At May 31, 2010, total debt was $6.8 million comprised of short and long-term bank debt issued in the
financing of our facility expansions in Queensbury, New York compared with total debt of $7.1 million at
May 31, 2009 for the same obligations.

We generated cash flow from operations of $40.0 million on net income of $12.3 million for fiscal 2010.
Significant non-cash expenses affecting net income included depreciation and amortization of $12.5 million,
deferred income tax provision of $5.9 million, and stock-based compensation of $4.9 million. Significant cash
provided by operating activities included a decrease in inventories of $8.3 million. The decrease in inventories is
primarily due to a successful company-wide inventory reduction program which focused on improved supply
chain management. The decrease in inventories was partially offset by increased accounts receivable due to
increased revenues.

For fiscal 2010, our investing activities used net cash of $11.8 million. We used cash for the acquisition of

intangible assets and businesses of $5.4 million, which was primarily the $5.0 million contractual payment
related to the Oncobionic acquisition. Additionally, we made equipment purchases and building improvements
totaling $5.0 million, including the furnishing of the new facility in Latham, New York and improvements to the
existing facilities in Queensbury, New York and Manchester, Georgia.

Financing activities added net cash of $2.7 million for fiscal 2010. This primarily consists of the proceeds

from the exercise of stock options and issuances under the employee stock purchase plan.

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 ($2.3 million at May 31, 2010) 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 1.75% and is in effect until August 24, 2010.

52

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 1.75% and is in effect until December 2010. 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 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 use of low energy direct current ablation technology
in the first human clinical trial for the treatment of soft tissue in April 2008. Under the stock purchase agreement,
we agreed to pay a total purchase price of $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 $5.0 million in
November 2009.

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. 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. Intangibles assets acquired,
other than goodwill, totaled approximately $3.7 million.

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. The
contingent payment is due within 50 days of the end of our fiscal year ended May 31, 2011.

In July 2009, we entered into an agreement to lease, for a ten year period plus 2 five year renewal options, a

52,500 square foot office building in Latham, New York to house our corporate headquarters and certain
business operations. We commenced occupancy of the facility in March 2010. The lease provides for annual rent
of $857,321 for the first five years and $943,054 for the next five years, plus the payment of customary building
operating expenses. The lease commencement date was March 1, 2010.

In July 2010, we entered into an agreement to extend the lease for our Manchester facility until April 30,

2013. The agreement terms are for an annual rent of $189,560 representing no change from the previous terms.

(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.

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, FASB issued authoritative guidance which establishes disclosure requirements for
arrangements entered into by companies to collaboratively develop, manufacture, or market products and which
also establishes income statement classification of collaboration transactions between the parties. We adopted
this guidance effective June 1, 2009 and the adoption had no impact on our consolidated financial statements.

In December 2007, FASB revised the authoritative guidance for business combinations, which 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. This
guidance 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 associated with
acquisitions that closed prior to the effective date of this policy which would also apply the provisions of this
policy. We adopted this guidance effective June 1, 2009 and the adoption had no impact on our consolidated
financial statements.

In December 2007, FASB issued authoritative guidance which establishes accounting and reporting
standards that require companies to more clearly identify in the financial statements and disclose the impact of
noncontrolling interest in a consolidated subsidiary on the consolidated financial statements. This guidance is
effective for fiscal years beginning after December 15, 2008 (our 2010 fiscal year), and interim periods within
those fiscal years. We adopted this guidance effective June 1, 2009 and the adoption had no impact on our
consolidated financial statements.

The FASB issued authoritative guidance for fair value measurements in September 2006, which defines fair

value, establishes a framework for measuring fair value and expands disclosures about assets and liabilities
measured at fair value in the financials statements. In February 2008, the FASB issued authoritative guidance
which deferred the effective date of this guidance for fair value measurements for one year for all nonfinancial
assets and liabilities, except those that are recognized or disclosed at fair value in the financial statements on a

54

recurring basis. We adopted this guidance for non-financial assets and liabilities that are recognized or disclosed
at fair value in the financial statements on a recurring basis effective June 1, 2009. The adoption of this guidance
had no impact on our consolidated financial statements.

In June 2008, the FASB issued guidance to determine whether instruments granted in share-based payment

transactions are participating securities. This guidance addresses whether instruments granted in share-based
payment transaction 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. This guidance 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 adopted this guidance effective June 1, 2009 and the
adoption had no impact on our consolidated financial statements.

In June 2008, the FASB issued authoritative guidance which establishes a two-step process for evaluating

whether an equity-linked financial instrument or embedded feature is indexed to the entity’s own stock. This
guidance determines that warrants which a company issues that contain a strike price adjustment feature results
in the instruments no longer being considered indexed to the company’s own stock. Accordingly, adoption of this
guidance will change the current classification (from equity to liability) and the related accounting for such
warrants outstanding at that date. This guidance is effective for fiscal years beginning after December 15, 2008
(our 2010 fiscal year), and interim periods within those fiscal years. We have adopted this guidance effective
June 1, 2009 and the adoption had no impact on our consolidated financial statements.

In April 2009, the FASB issued authoritative guidance which provides instruction for estimating fair value
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, the guidance requires disclosure in interim and annual periods of the inputs and valuation
techniques used to measure fair value. The guidance is effective for interim and annual periods ending after
June 15, 2009 (our 2010 fiscal year) and will be applied prospectively. We have adopted this guidance effective
June 1, 2009 and the adoption had no impact on our consolidated financial statements.

In April 2009, the FASB issued authoritative guidance which 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 This guidance is effective for acquisition dates on or after the beginning
of the first annual reporting period beginning on or after December 15, 2008 (our 2010 fiscal year). We adopted
this guidance effective June 1, 2009 and the guidance will be applied prospectively.

In April 2009, the FASB issued authoritative guidance which 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. 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, the policy 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. The guidance 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 have adopted this guidance effective June 1, 2009 and the adoption had no
impact on our consolidated financial statements.

55

In June 2009, the FASB issued the FASB Accounting Standards Codification (Codification). The

Codification will become the single source for all authoritative GAAP recognized by the FASB to be applied for
financial statements issued for periods ending after September 15, 2009. As the Codification was not intended to
change existing GAAP, it will not have any impact on our consolidated financial statements.

In October 2009, the FASB updated the revenue recognition accounting guidance relating to the accounting

treatment for revenue arrangements that involve more than one deliverable or unit of accounting. The updated
guidance allows companies to allocate arrangement considerations in multiple deliverable arrangements in a
manner that better reflects the economics of the transaction by revising certain thresholds for separation and
providing criteria for allocation of revenue among deliverables. The updated guidance is effective for
arrangements entered into in fiscal years beginning on or after June 15, 2010 (our 2012 fiscal year), but may be
adopted early. We have chosen early adoption effective with the third quarter of our fiscal 2010 year. The
adoption had no material effect on our consolidated financial statements.

In October 2009, the FASB updated the accounting guidance relating to certain revenue arrangements that
include software elements. The updated guidance clarifies the accounting for products that include both tangible
product and software elements. This amendment is effective for fiscal years beginning after June 15, 2010 (our
2012 fiscal year), but companies are required to adopt these amendments in the same period as the amendments
relating to revenue arrangements that involve more than one deliverable or unit of accounting. We have therefore
adopted the amendment effective with the third quarter of our fiscal 2010 year. The adoption had no material
effect on our consolidated 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, 2010, we maintained variable interest rate financing of $6.8 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 payments 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 fiscal 2010 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.

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
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, 2010

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.

57

Our management has assessed the effectiveness of our internal control over financial reporting as of

May 31, 2010. 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, 2010.

Our independent registered public accounting firm has issued an attestation report on the effectiveness of

our internal control over financial reporting. That report appears on page 61.

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, 2010 and May 31, 2009, and the results of their operations and their cash flows for each of the three
years in the period ended May 31, 2010 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, 2010, based on criteria
established in Internal 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, 2010 and May 31, 2009

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, RITA Medical Systems, LLC, and AngioDynamics UK Limited since June 17, 2008 (collectively,
the “Company”). All intercompany balances and transactions have been eliminated. To conform with the fiscal
2010 presentation, fiscal 2009 results include reclassifications made to include the costs of strategic business unit
management in marketing costs. The reclassifications resulted in an increase in marketing costs and a decrease in
general and administrative costs of $1,012,000 in fiscal 2009. We are 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, NanoKnife Ablation Systems, surgical resection systems
and embolization products for treating benign and malignant tumors.

Beginning with fiscal 2009, we organized our business into three reportable segments: Peripheral Vascular,
Access and Oncology/Surgery. The Peripheral Vascular segment is comprised of our venous, angiographic, PTA,
drainage and thrombolytic product lines. The Access segment is comprised of our dialysis, ports and PICC
product lines. The Oncology/Surgery segment is comprised of our RFA, embolization, Habib and NanoKnife
product lines. Our 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.

We have performed an evaluation of subsequent events through the date the financial statements were

issued.

Oncobionic, Inc.

On May 9, 2008, we 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, 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. 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. Intangibles assets acquired,
other than goodwill, totaled approximately $3.7 million (See Note C).

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. Intangible
assets acquired totaled approximately $1.3 million and inventory acquired totaled approximately $400,000.
(See Note C.)

2. Fiscal Year

Beginning with fiscal 2008, we report on a fiscal year ending May 31. Prior to fiscal 2008, we reported on a

fiscal year that concluded on the Saturday nearest to May 31.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

3. Cash and Cash Equivalents

We consider all unrestricted highly liquid investments purchased with an initial maturity of less than three
months to be cash equivalents. We maintain 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 authoritative
guidance issued by FASB and are 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. We hold 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 we may be
unable to liquidate our position in the securities in the near term. During both fiscal year 2010 and 2009, we 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. We perform ongoing credit
evaluations of our customers and adjust credit limits based upon payment history and the customer’s current
creditworthiness, as determined by a review of their current credit information. We continuously monitor aging
reports, collections and payments from customers, and a provision for estimated credit losses is maintained based
upon our historical experience and any specific customer collection issues that have been identified. While such
credit losses have historically 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.

Changes in our allowances for sales returns and doubtful accounts are as follows:

Beginning in fiscal 2010, we include a sales return allowance with the allowance for doubtful accounts. The
sales return allowance accounted for $1,286 of the total provision and $1,253 of the total write-offs during fiscal
2010. The allowance for doubtful accounts accounted for $68 of the total provision and $145 of the total write-
offs during fiscal 2010.

May 31, 2010 and May 31, 2009

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. We evaluate 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. 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 test 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 we began reporting three
operating segments as opposed to a single segment in prior periods. Our 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, 2009. Our assessment of goodwill
impairment indicated that the fair value of each of our reporting units exceeded its carrying value and therefore
goodwill in each of the reporting units was not impaired. (See Note G.)

9. Revenue Recognition

We recognize revenue in accordance with generally accepted accounting principles as outlined in the SEC’s

authoritative guidance on 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.

72

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

Decisions relative to criterion (iii) regarding collectibility are based upon our judgments, as discussed under
“Accounts Receivable” above, 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.

We have chosen to early adopt, effective with the third quarter of fiscal 2010, updated authoritative

guidance for revenue recognition relating to the accounting treatment for revenue arrangements that involve more
than one deliverable or unit of accounting. At the same time, we also adopted the updated guidance relating to
certain revenue arrangements that include software elements. Neither of these had a material effect on our
consolidated financial statements.

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 ,
enhancing existing products, validating new and enhanced products and managing clinical and regulatory affairs
and our intellectual property 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 $1,281,000, $909,000 and $555,000 for fiscal 2010, 2009 and 2008, 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, if 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 $2.1 million
had expired as of May 31, 2010) 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

We intend to reinvest indefinitely any of our unrepatriated foreign earnings as of May 31, 2010. We have

not provided for U.S. income taxes on these undistributed earnings of our foreign subsidiaries because we
consider such earnings to be reinvested indefinitely outside the United States. If these earnings were distributed,
we 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.

14. Fair Value of Financial Instruments

Our 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, we adopted an accounting policy regarding fair value. Under this policy, fair value is

defined 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. This policy 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 policy describes three levels of inputs that may be used to measure fair value which are provided in the table
below. The adoption of this policy had no impact on our financial statements other than the disclosures presented
herein.

Level 1

Level 2

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.

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
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.

74

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

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 both May 31, 2010 and 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.

The following tables provide information by level for assets and liabilities that are measured at fair value on

There were no changes in the level 3 fair value instruments during fiscal 2010.

In January 2010, the FASB updated the disclosure requirements for fair value measurements. The updated

guidance requires companies to disclose separately the investments that transfer in and out of Levels 1 and 2 and
the reasons for those transfers. Additionally, in the reconciliation for fair value measurements using significant

75

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

unobservable inputs (Level 3), companies should present separately information about purchases, sales, issuances
and settlements. The updated guidance is effective for annual and interim reporting periods beginning after
December 15, 2009 (our 2011 fiscal first quarter), except for the disclosures about purchases, sales, issuances and
settlements in the Level 3 reconciliation, which are effective for fiscal years beginning after December 15, 2010
(our 2012 fiscal year). We will provide the additional disclosures necessary for Levels 1 and 2 transfers
beginning with the report on form 10-Q for our fiscal 2011 first quarter.

15. Derivative Financial Instruments

In March 2008, FASB issued authoritative guidance which 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. This guidance also
improves the transparency about the location and amounts of derivative instruments in a company’s financial
statements and how they are accounted for. The guidance is effective for both interim and annual reporting
periods beginning after November 15, 2008. We have provided the required disclosures in the May 31, 2010
consolidated financial statements.

We are exposed to market risk due to changes in interest rates. To reduce that risk, we periodically enter

into certain derivative financial instruments to hedge its underlying economic exposure. We use derivative
instruments as part of our 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. We recognized interest expense of $70,000, $378,000 and $308,000 for the 2010, 2009 and 2008
periods, respectively, on the fair value hedge (See Note K).

In accordance with authoritative guidance on Accounting for Derivatives and Hedging Activities, as
amended, our 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

We recognize 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 recognize compensation expense for our stock awards on a straight-line basis
over the substantive vesting period.

The amount of stock-based compensation recognized is based on the value of the portion of awards that are

ultimately expected to vest. Guidance 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 94.4% of our options
will vest annually, and we have therefore applied a 5.6% annual forfeiture rate in determining the stock-based

76

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

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, 2010, May 31, 2009 and May 31, 2008, we used the Black-Scholes
option-pricing model (“Black-Scholes”) as our method of valuation 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 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 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.

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.

We account for convertible debt (see Note K) using authoritative guidance which 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, 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 restricted stock
units issued to employees and non-employees to purchase 2,325,215 shares of common stock at May 31, 2010 as
their inclusion would not be dilutive. The exercise prices of the excluded securities were between $0 and $53.92
at May 31, 2010. For the period ending May 31, 2009, options and warrants issued to employees and
non-employees to purchase 1,389,571 shares of common stock 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 $11.93 and $93.52 at May 31, 2009. For the period ending May 31, 2008, options,
warrants and restricted stock units issued to employees and non-employees to purchase 2,481,787, 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 May 31, 2008.

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

We are dependent on a third party supplier for our embolization product, LC Bead, which accounted for
approximately 10% of our sales in fiscal 2010. We are dependent on a third-party manufacturer for a substantial
portion of our dialysis catheters. In fiscal 2010, products purchased from this supplier accounted for
approximately 10% of total product purchases and sales of these products accounted for approximately 8% of our
sales. We are dependent upon the ability of our suppliers to provide products on a timely basis and on favorable
pricing terms. The loss of our principal suppliers or a significant reduction in product availability from these
suppliers could have a material adverse effect on us. We believe that our relationships with these suppliers are
satisfactory.

20. Recently Issued Accounting Pronouncements

In November 2007, FASB issued authoritative guidance which establishes disclosure requirements for
arrangements entered into by companies to collaboratively develop, manufacture, or market products and which
also establishes income statement classification of collaboration transactions between the parties. We adopted
this guidance effective June 1, 2009 and the adoption had no impact on our consolidated financial statements.

In December 2007, FASB revised the authoritative guidance for business combinations, which 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. This
guidance 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 associated with
acquisitions that closed prior to the effective date of this policy which would also apply the provisions of this
policy. We adopted this guidance effective June 1, 2009 and the adoption had no impact on our consolidated
financial statements.

In December 2007, FASB issued authoritative guidance which establishes accounting and reporting
standards that require companies to more clearly identify in the financial statements and disclose the impact of

78

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

noncontrolling interest in a consolidated subsidiary on the consolidated financial statements. This guidance is
effective for fiscal years beginning after December 15, 2008 (our 2010 fiscal year), and interim periods within
those fiscal years. We adopted this guidance effective June 1, 2009 and the adoption had no impact on our
consolidated financial statements.

The FASB issued authoritative guidance for fair value measurements in September 2006, which defines fair

value, establishes a framework for measuring fair value and expands disclosures about assets and liabilities
measured at fair value in the financials statements. In February 2008, the FASB issued authoritative guidance
which deferred the effective date of this guidance for fair value measurements for one year for all nonfinancial
assets and liabilities, except those that are recognized or disclosed at fair value in the financial statements on a
recurring basis. We adopted this guidance for non-financial assets and liabilities that are recognized or disclosed
at fair value in the financial statements on a recurring basis effective June 1, 2009. The adoption of this guidance
had no impact on our consolidated financial statements.

In June 2008, the FASB issued guidance to determine whether instruments granted in share-based payment

transactions are participating securities. This guidance addresses whether instruments granted in share-based
payment transaction 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. This guidance 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 adopted this guidance effective June 1, 2009 and the
adoption had no impact on our consolidated financial statements.

In June 2008, the FASB issued authoritative guidance which establishes a two-step process for evaluating

whether an equity-linked financial instrument or embedded feature is indexed to the entity’s own stock. This
guidance determines that warrants which a company issues that contain a strike price adjustment feature results
in the instruments no longer being considered indexed to the company’s own stock. Accordingly, adoption of this
guidance will change the current classification (from equity to liability) and the related accounting for such
warrants outstanding at that date. This guidance is effective for fiscal years beginning after December 15, 2008
(our 2010 fiscal year), and interim periods within those fiscal years. We have adopted this guidance effective
June 1, 2009 and the adoption had no impact on our consolidated financial statements.

In April 2009, the FASB issued authoritative guidance which provides instruction for estimating fair value
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, the guidance requires disclosure in interim and annual periods of the inputs and valuation
techniques used to measure fair value. The guidance is effective for interim and annual periods ending after
June 15, 2009 (our 2010 fiscal year) and will be applied prospectively. We have adopted this guidance effective
June 1, 2009 and the adoption had no impact on our consolidated financial statements.

In April 2009, the FASB issued authoritative guidance which 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 This guidance is effective for acquisition dates on or after the beginning
of the first annual reporting period beginning on or after December 15, 2008 (our 2010 fiscal year). We adopted
this guidance effective June 1, 2009 and the guidance will be applied prospectively.

In April 2009, the FASB issued authoritative guidance which amends the other-than-temporary guidance for

debt securities and requires additional interim and annual disclosures of other-than-temporary impairments on

79

AngioDynamics, Inc. and Subsidiaries

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

debt and equity securities. 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, the policy 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. The guidance 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 have adopted this guidance effective June 1, 2009 and the adoption had no
impact on our consolidated financial statements.

In June 2009, the FASB issued the FASB Accounting Standards Codification (Codification). The

Codification will become the single source for all authoritative GAAP recognized by the FASB to be applied for
financial statements issued for periods ending after September 15, 2009. As the Codification was not intended to
change existing GAAP, it will not have any impact on our consolidated financial statements.

In October 2009, the FASB updated the revenue recognition accounting guidance relating to the accounting

treatment for revenue arrangements that involve more than one deliverable or unit of accounting. The updated
guidance allows companies to allocate arrangement considerations in multiple deliverable arrangements in a
manner that better reflects the economics of the transaction by revising certain thresholds for separation and
providing criteria for allocation of revenue among deliverables. The updated guidance is effective for
arrangements entered into in fiscal years beginning on or after June 15, 2010 (our 2012 fiscal year), but may be
adopted early. We have chosen early adoption effective with the third quarter of our fiscal 2010 year. The
adoption had no material effect on our consolidated financial statements.

In October 2009, the FASB updated the accounting guidance relating to certain revenue arrangements that
include software elements. The updated guidance clarifies the accounting for products that include both tangible
product and software elements. This amendment is effective for fiscal years beginning after June 15, 2010 (our
2012 fiscal year), but companies are required to adopt these amendments in the same period as the amendments
relating to revenue arrangements that involve more than one deliverable or unit of accounting. We have therefore
adopted the amendment effective with the third quarter of our fiscal 2010 year. The adoption had no material
effect on our consolidated financial statements.

We record comprehensive income in accordance with authoritative guidance which requires unrealized
holding gains or losses on available-for-sale securities and certain derivative instruments, net of tax, and foreign
currency translation to be included in accumulated other comprehensive income, as a separate component of
stockholders’ equity. The components of comprehensive income, which include unrealized gains and losses on
available for sale securities, changes in the fair value of the 2002 interest rate swap (see Note K), and foreign
currency translation losses, are detailed in our accompanying consolidated statements of stockholders’ equity and
comprehensive income. At May 31, 2010 and May 31, 2009, the components of accumulated other

NOTE C—ACQUISITIONS

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 has been accounted for as
a purchase and, accordingly, we have included the results of operations in the financial statements effective
January 12, 2009. 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 has been accounted for as a purchase and, accordingly, we have included the results of
operations in the financial statements effective June 17, 2008. 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 low energy direct current ablation technology
in the first human clinical trial for the treatment of soft tissue in 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,
$5.0 million in November 2008 and $5.0 million 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 low energy direct current to achieve tissue ablation by inducing
irreversible electroporation. 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. Substantially all of the purchase price was recorded as product technology and is being
amortized over a 15 year useful life. We have 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.

Acquisition of RITA Medical Systems, Inc.

On January 29, 2007, we 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 our common stock and assumption of outstanding RITA options and other convertible securities. We
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 rate 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 we believed to
be reasonable as of the date of the acquisition. During the fiscal year ended May 31, 2009, we benefitted from the
tax deduction of costs incurred related to the acquisition of RITA. 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 below as an adjustment to purchase price allocation.

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 our 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.

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

84

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

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 test 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 we began reporting three
operating segments as opposed to a single segment in prior periods. Our 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 our reporting units on a relative fair value basis. We completed our
annual evaluation of goodwill by reporting unit as of December 31, 2009. Our assessment of goodwill
impairment indicated that the fair value of each of our 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 26%, 6% and 16%, 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 8% as of December 31, 2009.

To determine fair value, we utilized two market-based approaches and an income approach. Under the
market-based approaches, we utilized information regarding our own 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 2011, followed by a recovery thereafter.
In addition, we applied gross margin assumptions consistent with our historical trends at various revenue levels
and used an EBITDA exit multiple of 6.0, 6.0 and 7.0 to calculate the terminal value of the Peripheral Vascular,
Access and Oncology/Surgery reporting units, respectively, compared to an EBITDA exit multiple of 6.5, 7.0
and 8.0, respectively, used in the prior year. In addition, we used a discount rate of 21%, 15% and 18% to
calculate the fair value of our Peripheral Vascular, Access and Oncology/Surgery reporting units, respectively.
These discount rates vary from the rates of 19%, 16% and 19%, respectively, used in the prior year.

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 2010 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, 2009, 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, 2010. 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.

There were no changes in the carrying amount of goodwill for the fiscal year ended May 31, 2010.

During the fiscal year ended May 31, 2009, we 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

At May 31, 2010, we had approximately $56.6 million of remaining Federal net operating loss

carryforwards and $26.8 million of state net operating loss carryforwards (“NOL”) which were generated by an
acquired company. These net operating losses are subject to Internal Revenue Code (“IRC”) Section 382
limitations which is expected to significantly limit our ability to utilize these net operating losses on an annual
basis. As a result of our IRC Section 382 analysis, it is estimated that approximately $13.6 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.

We need to generate approximately $3 million of taxable income in each year over the next sixteen 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 sheets.

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, 2010 after considering IRC Section 382
limitations are $43.0 million. The expiration of the Federal net operating loss carryforwards are as follows: $0.3
million in 2011, $26.6 million between 2017 and 2021 and $16.1 million between 2022 and 2026.

Our state net operating loss carryforwards as of May 31, 2010 after considering remaining IRC Section 382

limitations are $15.0 million which expire in various years from 2011 to 2026.

At May 31, 2010, we had approximately $449,000 of Federal research and development tax credit
carryforwards which are subject to IRC Section 382 limitations and begin to expire in 2023. Additionally, at
May 31, 2010, we had $1.7 million of state credits, of which $315,000 expire at various dates through 2013 and
$1,385,000 which have an unlimited carryforward period.

At May 31, 2010, we had a net deferred income tax asset of $7.8 million, after recording a valuation
allowance of $1.2 million. The net change in the valuation allowance was a decrease of $9,000 in 2010 and an
increase of $17,000 in 2009. The 2010 decrease relates to the use of fully reserved state tax credits due to a
temporary change in state tax law partially offset by capital losses incurred in 2010 which are fully reserved. The
2009 increase relates to fiscal year 2009 capital losses which are fully reserved. The valuation allowance
recorded against the deferred tax assets 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.

In July 2006, the Financial Accounting Standards Board (FASB) issued authoritative guidance on

accounting for uncertainty in income taxes, which clarifies the accounting for uncertainty in tax positions. This
guidance seeks to reduce the diversity in practice associated with certain aspects of the recognition and
measurement related to accounting for income taxes. This guidance 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 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 guidance on June 3, 2007. There was no cumulative effect of adoption. Upon adoption,
the liability for unrecognized tax benefits was zero.

During the twelve months ended May 31, 2010, we did not recognize any tax liabilities related to uncertain
tax positions. Due to our unrecognized tax benefit 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.

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 guidance issued with
respect to uncertain tax positions. Accrued interest and penalties recognized in the consolidated balance sheet
were $0 as of May 31, 2010 and May 31, 2009.

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 2007 through 2010 remain open to examination by the various tax authorities. We analyzed our
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 filings position and deductions will be
sustained on audit and do not anticipate any adjustments will result in a material adverse effect on our financial
condition, results of operations or cash flows.

We do 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, we 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 we have named Centros™. We also have the option to purchase certain
intellectual property associated with these products in the future. We will pay royalties on net sales of the
products covered in the Agreement. In accordance with the Agreement, we have prepaid $3.0 million of royalties
based upon the achievement of certain milestones. The balance of $2.9 million has been included in the caption
“Prepaid Royalties” on the balance sheet as of May 31, 2010 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, we closed on the financing for the expansion of our 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 us. 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, we 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 current fee is 1.75% and is in effect until August 24, 2010. 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 such bonds in the secondary market. The Remarketing Agreement provides for the payment of an
annual fee of 0.1% of the remaining balance.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

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.

We 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 the rollover of the Bonds. The Swap Agreement, which qualifies for hedge accounting under
authoritative guidance, 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 us 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, 2010, May 31, 2009 and May 31, 2008, since the Swap Agreement
is classified as a cash flow hedge, the fair value of $327,000, $319,000 and $196,000, respectively, has been
recorded as a component of accrued liabilities, and accumulated other comprehensive loss related to the swap
agreement is $207,000, $201,000 and $123,000, respectively, net of tax.

We capitalized certain legal and administrative costs incurred in connection with the issuance of the Bonds

and are amortizing these costs using the effective interest method over the term of the Bonds. As of May 31,
2010, May 31, 2009 and May 31, 2008, net capitalized bond issuance costs amounted to $69,000, $74,000 and
$80,000, 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, we closed on the financing for the expansion of our warehouse and manufacturing
facility in Queensbury, New York. The expansion is being financed principally with Taxable Adjustable Rate
Notes (the “Notes”) issued by us aggregating $5,000,000, maturing in December 2026. The Notes were issued
under a Trust Agreement by and between us 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, we 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. The current fee is 1.75% and is in effect until December 2010. We 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 our assets.

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 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 we did not elect to apply hedge
accounting. As of May 31, 2010 and May 31, 2009, the fair value of $668,000 and $599,000, respectively has
been recorded as a component of accrued liabilities with a corresponding credit to other income in the
consolidated statement of operations.

We capitalized certain legal and bank fees incurred in connection with the issuance of the Notes and are
amortizing these costs on a straight-line basis over the term of the Notes. As of May 31, 2010 and May 31, 2009,
net capitalized issuance costs related to these Notes amounted to $159,000 and $168,000, respectively, and are
recorded as a component of other assets.

Convertible Notes

In connection with the acquisition of RITA on January 29, 2007, we assumed subordinated Senior
Convertible Notes of RITA (the “Convertible Notes”) with an aggregate principal amount of $9.7 million. The
fair value of the conversion feature of the Convertible Notes of $1.8 million was calculated using the intrinsic
value method and recorded in goodwill and stockholders’ equity as part of the purchase price described in
Note C. During the year ended May 31, 2009, the Convertible Notes matured and were paid in cash.

principal owner is the spouse of our then President and CEO. Fees and expenses paid for these services totaled
$63,000 and $108,000, respectively.

NOTE M—RETIREMENT PLANS

We have a profit-sharing plan under which we make discretionary contributions to eligible employees, and a

companion 401(k) plan under which eligible employees can defer a portion of their compensation, part of which
is matched by us. Profit-sharing contributions were $1,087,900, $1,009,000 and $948,700, in 2010, 2009 and
2008, respectively. Matching contributions were $706,100, $507,800 and $499,500, in 2010, 2009 and 2008,

NOTE N—STOCKHOLDERS’ EQUITY

1. Capitalization

On February 27, 2004, our Board of Directors and the Former Parent, as sole stockholder, approved our
Amended and Restated Certificate of Incorporation (the “Amended Certificate”). Under the Amended Certificate,
the authorized capital stock 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 we liquidate, dissolve, or wind 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 we may designate in the future.

Our 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 our stockholders.

2. Stock Options

We have 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, we 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 our 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 our 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.

May 31, 2010 and May 31, 2009

2004 Stock and Incentive Award Plan

The 2004 Stock and Incentive Award Plan (the “2004 Plan”) provides for the grant of incentive options to

our employees and for the grant of non-statutory stock options, restricted stock, stock appreciation rights,
performance units, performance shares and other incentive awards to our employees, directors and other service
providers. A total of 3,000,000 shares of our 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 our 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, we 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. We
do not anticipate future grants will be made under these plans. As of May 31, 2010, RITA Options to acquire
260,382 shares of our common stock were outstanding, of which RITA Options to acquire 258,042 shares of our
common stock were exercisable.

In accordance with the Merger Agreement, the options held by RITA employees became exercisable for

shares of our common stock and a fixed cash component payable to the holder at option exercise . Under
authoritative guidance on share based payment awards, 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. We
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:

On May 31, 2010, there remained 1,033,710 shares available for granting of options under the 2004 Plan.

Options are exercisable into common stock.

All of our options were granted at exercise prices equal to the quoted market price of our 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 $862,117, $839,022 and $2,787,000 for the years
ended May 31, 2010, May 31, 2009 and May 31, 2008, respectively. We generally issue authorized but unissued
shares upon stock option exercises and the settlement of performance share awards and restricted stock units.

The fair value of the options granted under the 1997 and 2004 Plans was estimated at the date of grant using

the Black-Scholes option-pricing model assuming no expected dividends and the following weighted-average

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 us. 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 us,
competes with our business or otherwise engages in activities detrimental to our business before such date. The
performance share awards and restricted stock units settle in shares of our common stock on a one-for-one basis.

We value performance share and restricted stock unit awards based on the closing trading value of our
shares on the date of grant. We recognize the compensation cost related to our 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 authoritative guidance on share
based payment awards.

5. Employee Stock Purchase Plan

The Employee Stock Purchase Plan (the “Stock Purchase Plan”) provides a means by which our employees

(the “participants”) are given an opportunity to purchase our common stock through payroll deductions. The
maximum number of shares to be offered under the Stock Purchase Plan is 400,000 shares of our 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 our 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.

We use the Black-Scholes option-pricing model to calculate the purchase date fair value of the shares issued

under the Stock Purchase Plan and recognize expense related to shares purchased ratably over the offering
period.

For the years ended May 31, 2010, May 31, 2009 and May 31, 2008, 114,479, 92,937 and 57,011, shares,

respectively, were issued at an average price of $10.09, $11.75 and $14.33, respectively, under the Stock
Purchase Plan. As of May 31, 2010, 70,005 shares remained available for future purchases under the Stock
Purchase Plan.

6. Warrants

In connection with the acquisition of RITA, we assumed warrants to acquire 2,727,270 RITA shares, which,
following the completion of the acquisition became exercisable for approximately 469,636 shares of our common
stock at an average price of $20.24 per share, net of the cash component. These warrants expired unexercised 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.

NOTE O—STOCK-BASED COMPENSATION

We adopted authoritative guidance for share based payment awards using the modified prospective
transition method which requires the application of the guidance as of June 4, 2006, the first day of our 2007
fiscal year. Our consolidated financial statements as of and for the years ended May 31, 2010, May 31, 2009 and
May 31, 2008, reflect the impact of the application of this guidance. In accordance with the modified prospective
transition method, our consolidated financial statements have not been restated to include the impact of such
application. Stock-based compensation expense recognized under this method for the years ended May 31, 2010,
May 31, 2009 and May 31, 2008, was $3,124,300, net of income taxes of $1,788,700, $3,662,000, net of income
taxes of $2,129,000 and $3,421,000, net of income taxes of $1,478,000, respectively.

The following table summarizes stock-based compensation in accordance with authoritative guidance on
share based payment awards for the years ended May 31, 2010, May 31, 2009 and May 31, 2008, which was

NOTE P—ASSET PURCHASE AGREEMENTS

Medron, Inc.

On May 1, 2006, we entered into an Asset Purchase Agreement (the “Agreement”) with Medron, Inc. to

acquire the rights, titles, and interests in, and to, Patent Pending Technology for purposes of manufacturing,
marketing, and selling proprietary Vascular Access Ports, following administrative approval. As of May 31,
2010, we have paid $5.5 million in accordance with the Agreement. That amount, net of accumulated
amortization, has been included on the balance sheet under the caption “Intangible assets” and is being amortized
on a straight line basis over the expected useful life of the assets. A potential future payment of $2.5 million is
due upon issuance (within 10 years of the effective date of the Agreement) of a U.S. patent claiming priority to
the Patent Application, or any issuance of a patent to us within 10 years of the effective date of the Agreement in
which the original owners are the inventors.

Nevertouch®

On August 20, 2007, we entered into an agreement to acquire all technology rights, including patent rights to

the NeverTouch technology (the “Agreement”). As of May 31, 2010, we have made payments of approximately
$3.0 million which have been recorded on the balance sheet, net of accumulated amortization, under “Intangible
assets” and are being amortized on a straight line basis over the expected useful life of the asset.

Litigation Matters

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’
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. Vascular Solutions has filed with the U.S. Patent & Trademark Offices, or PTO, requests for inter partes
reexamination of the ‘478 and ‘329 patents. The PTO has initiated reexamination of these patents. No final ruling on
the merits has been made at this time. Vascular Solutions has denied the allegations of infringement and has
counterclaimed for a declaratory judgment that it does not infringe, that the patents are invalid and that the patents
are unenforceable as a result of alleged inequitable conduct. Vascular Solutions does not seek damages but does
seek attorney’s fees and costs of an unspecified amount should it prevail on its counterclaims and defenses.
AngioDynamics intends to vigorously pursue its claims and defend against Vascular Solutions’ counterclaims. The
case has been transferred to the United States District Court for the District of Minnesota, and is currently in the
discovery stage and no ruling has been made on the merits of any claim, defense, or counterclaim.

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 judgment against biolitec for
defense and indemnification costs we incurred in the Diomed action and the VNUS action described elsewhere in
this report. 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.

On October 26, 2009, we commenced an action in the United States District Court for the District of
Massachusetts entitled AngioDynamics, Inc. v. biolitec AG, et al. In this action, we are asserting claims of
tortious interference with contract, piercing the corporate veil, declaratory judgment, fraudulent transfer, and
unfair or deceptive business practices against biolitec, Inc., biolitec AG (the corporate parent of biolitec, Inc.), a
shareholder of biolitec AG, and an executive of biolitec AG. The defendants have not yet answered, and no
counterclaims have been asserted against us to date.

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
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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

May 31, 2010 and May 31, 2009

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. This payment was made in fiscal 2009.
In addition, we agreed to pay a quarterly royalty on our U.S. sales of our Nevertouch® , 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-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.

Future Purchase Obligations

On October 17, 2005, we entered into a Supply and Distribution Rights Agreement (the “Agreement”) with

Bioniche Pharma Group Limited (“Bioniche”). We were 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 indicated in the treatment of small
uncomplicated varicose veins of the lower extremities that show simple dilation with competent valves. The
Agreement was amended and restated during fiscal 2010 and expires on June 30, 2012. Future obligations under
the agreement are as follows:

• We agreed to purchase a minimum of 120,000 units of Product for fiscal year 2011 and 80,000 units of
Product for each of the remaining years of the contract though the expiration date (June 30, 2012). We
met our purchase commitment for the year ended June 30, 2010. Failure to make certain minimum
annual purchases in any two consecutive contract years, unless cured as provided in the
Agreement, may result in a loss of exclusive rights under the Agreement.

We have 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: $19.0 million in
2011, $6.2 million in 2012, $1.9 million in 2013, and $2.2 million in 2014.

NOTE R—SEGMENTS AND GEOGRAPHIC INFORMATION

Segment information

Prior to fiscal 2009, we reported our results of operations as a single segment. At the beginning of fiscal

The results for fiscal year ended May 31, 2008 have been presented to reflect the three reportable segments
for net sales and gross profit. Operating income and total assets for 2008 have not been previously disclosed as it
is impracticable to do so.

In accordance with authoritative guidance on disclosures about segments, the internal organization that is

used by management for making operating decisions and assessing performance is used as the source of our
reportable segments. Our 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.

We market our 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 our clinical testing outside of the United States. The loss of any
international distributor would not have a material adverse effect on our business if a new distributor, sales
representative or other suitable sales organization could not be found on a timely basis. For fiscal years 2010,
2009 and 2008, International sales as a percentage of total net sales were 10.7%, 11.1% and 9.5% 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
