PART I

ITEM 1.  BUSINESS

THE COMPANY

Boston Scientific Corporation (the "Company") is a worldwide developer,
manufacturer and marketer of less-invasive medical devices. The Company's
products are used in a broad range of interventional medical specialties,
including interventional cardiology, peripheral intervention, neurovascular,
electrophysiology, vascular surgery, gastroenterology, gynecology, oncology and
urology. The Company's products are generally inserted into the human body
through natural openings or small incisions in the skin and can be guided to
most areas of the anatomy to diagnose and treat a wide range of medical
problems. These products provide effective alternatives to traditional surgery
by reducing risk, trauma, cost, procedure time and the need for aftercare.

The Company's history began in the late 1960s when the Company's co-founder,
John Abele, acquired an equity interest in Medi-tech, Inc., a development
company. Medi-tech's initial products, a family of steerable catheters, were
introduced in 1969. They were used in some of the first less-invasive procedures
performed, and versions of these catheters are still being sold today. In 1979,
John Abele joined with Pete Nicholas to form the Company, which indirectly
acquired Medi-tech, Inc. This acquisition began a period of active, focused
marketing, new product development and organizational growth. Since then, the
Company's net sales have increased substantially, growing from $1.8 million in
1979 to more than $2.9 billion in 2002.

The Company's growth has been fueled in part by strategic acquisitions and
alliances designed to improve the ability of the Company to take advantage of
growth opportunities in less-invasive medicine. These acquisitions have helped
the Company to achieve a strategic mass which allows it to offer one of the
broadest product lines in the world for use in less-invasive procedures. The
Company's strategic mass has also enabled it to compete more effectively in, and
better absorb the pressures of, the current health care environment of cost
containment, managed care, large buying groups and hospital consolidations.

CORONARY STENTS AND THE DRUG ELUTING STENT OPPORTUNITY

During 2002, the Company reestablished its position in the coronary stent market
with the highly competitive Express(TM) coronary stent system. The Company also
marketed its next-generation coronary angioplasty balloon, the Maverick(R)
balloon dilatation catheter, now the market leader. The Company then combined
the original Express stent with the advanced Maverick balloon catheter
technology to create the Express(2) stent system, which was launched in Europe
and the United States during the year. As a result, at the end of 2002 the
Company regained leadership in the cardiovascular and peripheral vascular
catheter labs.

The Company believes that the combination of drugs and coronary stents offers
the possibility of a more lasting solution for coronary artery disease,
particularly the processes that lead to instent restenosis, the growth of
neointimal tissue within an artery after angioplasty and stenting. Drug-eluting
stents are expected to reduce the need for repeat procedures - or more expensive
surgical procedures - and to significantly reduce health care costs, as well as
overall patient risk, trauma, procedure time and the need for post-procedural
care.

Since 1997, the Company has been developing a proprietary polymer-based,
paclitaxel-eluting stent technology for reducing coronary restenosis. The
Company's TAXUS(TM) paclitaxel-eluting coronary stent system is built on the
Express stent technology. The conformability of the stent within a diseased
coronary artery benefits the Company's polymer-based drug eluting technology and
contributes to the clinical differentiation of the TAXUS drug-eluting stent
platform from others.

The Company has invested in the TAXUS clinical program, a series of studies
designed to collect data on the TAXUS paclitaxel-eluting stent. Prior studies
have demonstrated promising results by dramatically reducing restenosis. The
proprietary polymer on the stent allows for controlled delivery of paclitaxel.
Paclitaxel is a multi-functional microtubular inhibitor that controls platelets,
smooth muscle cells and white blood cells, all of which are believed to
contribute to restenosis.

                                      -4-



An overview of the Company's TAXUS clinical program, initiated in 1997, is
presented below.

The Company has also initiated a transitional registry program (WISDOM) as part
of a limited international commercial launch. This multi-center, prospective,
observational registry is collecting and analyzing "real world" data on the
performance of the TAXUS paclitaxel-eluting stent system for the treatment of
patients with coronary artery disease. A registry program enlists large numbers
of clinicians to document the performance of a specific therapy for a particular
disease or condition. To date, this registry has enrolled more than 400
patients.

In March 2003, the Company began a post-approval European registry (Milestone
II) with the TAXUS coronary stent system. This registry is targeting 100 sites
and plans to enroll 2,000 patients to study real-world usage patterns.

To support commercialization of the TAXUS coronary stent system in the United
States, the Company submitted the first two modules of its application for
Pre-Market Approval to the Food & Drug Administration ("FDA") during February
and March 2003. A total of five modules are expected to be submitted between
February and June 2003. The last module will include data from the TAXUS IV
clinical trial. In March 2003, the FDA notified the Company that it had granted
the TAXUS coronary stent system "expedited review" status, which means that the
application is designated to receive priority review before other pending
applications. The Company expects to launch the TAXUS paclitaxel-eluting
coronary stent in the United States in late 2003 and in Japan in early 2005,
pending regulatory approvals.

The worldwide coronary stent market is dynamic and highly competitive with
significant market share volatility. The introduction of drug-eluting stents is
likely to have a significant impact on the market size for coronary stents and
on the distribution of market share across the industry. The Company believes
drug-eluting stent technology represents one of the largest market opportunities
in the history of the medical device industry. It is estimated that the annual
worldwide market for coronary stents, including drug-eluting stents, may grow to
$5 billion by 2005, compared to approximately $2.2 billion today. Although the
Company believes it is positioned to be one of only two early entrants in this
market, uncertainties exist about the rate of development and size of this new
market. The Company's success with drug-eluting stents could be adversely
affected by more gradual physician adoption rates, changes in reimbursement
policies, delayed or limited regulatory approvals, unexpected variations in
clinical results, the earlier availability of a competitor's technology, third
party intellectual property, the outcome of litigation and the availability of
inventory to meet customer demand. A more gradual physician adoption rate may
limit the number of procedures in which the technology may be used and the price
at which institutions may be willing to purchase the technology. Together, these
and other factors contribute to the uncertainty surrounding the evolution of the
drug-eluting stent market and the Company's position in it.

BUSINESS STRATEGY

The Company's mission is to improve the quality of patient care and the
productivity of health care delivery through the development and advocacy of
less-invasive medical devices and procedures. This is accomplished through the
continuing refinement of existing products and procedures and the investigation
and development of new technologies that can reduce risk, trauma, cost,
procedure time and the need for aftercare. The Company's approach to innovation
combines internally developed products and technologies with those obtained
externally through strategic acquisitions and alliances.

Key elements of the Company's overall business strategy are as follows:

Innovation. The Company is committed to driving growth through harnessing
technological innovation both in the near and long term. The Company's approach
to enhancing innovation includes a mixture of tactical and strategic initiatives
that are designed to offer sustainable growth. Combining internally developed
products and technologies with those obtained through acquisition and alliances
allows the Company to focus on and deliver new products currently in its
pipeline as well as strengthen the Company's technology portfolio and
development processes and tools.

Product Diversity. The Company offers products in numerous product categories
which are used by physicians throughout the world in a broad range of diagnostic
and therapeutic procedures. The breadth and diversity of the Company's product
lines permit medical specialists to satisfy many of their less-invasive medical
device requirements from a single source.

Clinical Excellence. The Company's commitment to innovation is further
demonstrated by its rapidly expanding clinical capabilities. The Company's
clinical teams are organized by therapeutic specialty to better align with
research and development, marketing and sales teams. During 2002, the clinical
organization planned, initiated and conducted a series of focused clinical
trials that support regulatory requirements and demonstrate the safe and
effective clinical performance of products and technologies.

Operational Excellence. The Company is focused on continuously improving its
supply chain effectiveness, strengthening its manufacturing processes and
optimizing its plant network in order to increase operational efficiencies
within the organization and generate savings. By centralizing its operations at
the corporate level and shifting global manufacturing along product lines, the
Company is able to leverage its existing resources and concentrate on new
product development and launch.

Focused Marketing. Each of the Company's business groups maintain dedicated
sales forces and marketing teams focusing on physicians who specialize in the
diagnosis and treatment of different medical conditions and offer products to
satisfy their needs. The Company believes that this focused disease state
management enables it to develop highly knowledgeable and dedicated sales
representatives and to foster close professional relationships with physicians.

                                      -9-



Active Participation In The Medical Community. The Company believes that it has
excellent working relationships with physicians and others in the medical
industry which enable it to gain a detailed understanding of new therapeutic and
diagnostic alternatives, and to respond quickly to the changing needs of
physicians and patients. Active participation in the medical community
contributes to physician understanding and adoption of less-invasive techniques
and the expansion of these techniques into new therapeutic and diagnostic areas.

Corporate Culture. Management believes that success and leadership evolve from a
motivating corporate culture which rewards achievement, respects and values
individual employees and customers, and has a long-term focus on quality,
technology, integrity and service. The Company believes that its success is
attributable in large part to the high caliber of its employees and the
Company's commitment to respecting the values on which its success has been
based.

PRODUCTS

The Company's products are offered by two dedicated business groups -
Cardiovascular and Endosurgery. During 2002, the Cardiovascular organization
focused on products and technologies for use in interventional cardiology,
interventional radiology, electrophysiology, peripheral vascular intervention
and neurovascular procedures. The Endosurgery organization focused on products
and technologies for use in oncology, vascular surgery, endoscopy, urology and
gynecology procedures. During 2002, approximately 68% of the Company's net sales
were derived from the Company's Cardiovascular business and approximately 32%
from its Endosurgery business.

The Company's principal Cardiovascular and Endosurgery products are offered in
the following medical areas:

                                 CARDIOVASCULAR

Coronary Revascularization. The Company markets a broad line of products used to
treat patients with atherosclerosis. Atherosclerosis, a coronary vessel disease
and a principal cause of heart attacks, is characterized by a thickening of the
walls of the arteries and a narrowing of arterial lumens (openings) caused by
the progressive development of deposits of plaque. The majority of the Company's
products in this market are used in percutaneous transluminal coronary
angioplasty ("PTCA") and percutaneous transluminal coronary rotational
atherectomy and include PTCA balloon catheters, the Rotablator(R) and
Rotalink(R) rotational atherectomy systems, guide wires, guide catheters and
diagnostic catheters. In 2002, the Company's Maverick(R) balloon dilatation
catheter, offered for commercial sale around the world, became the market
leading angioplasty catheter. The Maverick balloon catheter features
TrakTip(TM), which creates a flexible kink-resistant taper. The TrakTip's low
lesion entry profile is designed to enable excellent crossability and easy
lesion engagement. In December 2002, the Company launched two new balloon
catheters in the United States, the Maverick(2)(TM) Monorail(R) Coronary Balloon
Dilatation Catheter and the Quantum(TM) Maverick(R) Coronary Balloon Dilatation
Catheter.

                                      -10-



The Company also offers the Cutting Balloon(TM) catheter, a balloon angioplasty
device that combines features of conventional angioplasty with advanced
microsurgical technology. During 2002, the Company launched the Cutting
Balloon(TM) Monorail(R) Device and expects to launch the Cutting Balloon
Ultra(2)(TM) Microsurgical Dilatation Catheter in the United States during 2003,
pending regulatory approval.

Coronary Stents. The Company markets both balloon-expandable and self-expanding
coronary stent systems. Coronary stents are tiny, mesh tubes used in the
treatment of coronary artery disease and implanted in patients to prop open
arteries and facilitate blood flow to the heart.

During 2002, the Company launched its Express(2)(TM) coronary stent system in
the United States, Europe and other international markets and expects to launch
the product in Japan later in 2003. The Express(2) coronary stent system,
developed exclusively by the Company, features two of its most impressive
technologies - the Express stent and the Maverick(R) balloon dilatation
catheter. The Express stent is a laser-cut, balloon-expandable stent that
features a unique design concept called Tandem Architecture(TM). The Tandem
Architecture stent design integrates short, thin Micro(TM) elements designed for
flexibility and conformability, with long, wide Macro(TM) elements designed to
enhance radiopacity. The Express(2) stent system features a laser-bonded,
flexible tip with a long, low profile designed for easier tracking.

Fluid Management. The Company markets a broad line of fluid delivery sets,
pressure monitoring systems, custom kits and accessories that provide for the
injection of contrast and saline or the withdrawal and disposal of bodily waste.

Electrophysiology. The Company's electrophysiology product offerings include
catheters and systems for use in less-invasive procedures to diagnose and treat
tachyarrhythmias (abnormally fast heart rhythms). The Company markets RF
generators, mapping systems, intracardiac ultrasound and steerable ablation
catheters, many of which incorporate proprietary steering, temperature
monitoring and control technology, as well as a line of diagnostic catheters and
associated accessories. The Company also offers the Chilli(R) cooled ablation
catheter and Realtime Position Management(TM) system. These products are
designed for ablating (neutralizing) the tissue in the heart that is responsible
for starting or maintaining the tachyarrhythmia and for navigating EP catheters
within the heart.

Peripheral Vascular Intervention. The Company sells various products designed to
treat patients with peripheral vascular disease (disease which appears in blood
vessels other than in the heart), including a broad line of medical devices used
in percutaneous transluminal angioplasty and thrombolysis (the catheter-based
delivery of clot dissolving agents directly to the site of a blood clot).
Additionally, the Company's peripheral vascular product line includes balloon
catheters, thrombectomy catheters, and stents (including the Wallstent(R)
endoprosthesis).

                                      -11-



Embolic Protection. One of the most promising areas in interventional medicine
is embolic protection. Internationally, the Company offers the Filterwire EX(TM)
device, which is designed to capture material dislodged into the bloodstream
during cardiovascular interventions, potentially preventing a heart attack or
stroke. The FilterWire EX device is available for use in coronary, saphenous
vein graft, carotid and peripheral vessel applications in markets outside the
United States. During the fourth quarter of 2002, the Company submitted an
application to the FDA for 510(k) clearance to market the Filterwire EX device
for saphenous vein graft application in the United States.

Caval Interruption Systems. The Company markets the Greenfield(R) vena cava
filter system for use in patients who are at risk of developing a pulmonary
embolism due to an existing medical condition or post-surgical complications.
Once the filter is implanted, circulating emboli (blood clots) can be captured
and held by the lattice design of the filter, allowing the clots to dissolve
naturally before they can reach the pulmonary system. The Company expects to
launch a new reduced profile vena cava filter, the Greenfield(R) RP Vena Cava
Filter, later in 2003, pending regulatory approval.

Intraluminal Ultrasound Imaging. The Company markets a family of intraluminal
catheter-directed ultrasound imaging catheters and systems for diagnostic use in
blood vessels, heart chambers and coronary arteries, as well as certain
nonvascular systems.

Neurovascular Interventions. The Company markets a line of micro-guidewires,
micro-catheters, guiding catheters and embolics to treat diseases of the
neurovascular system. The Company also markets the GDC(R) (Guglielmi Detachable
Coil) system to treat and prevent the rupture of cerebral aneurysms that are
otherwise either considered to be inoperable or high risk for surgery. Results
from the International Subarachnoid Aneurysm Trial (ISAT) demonstrated that
less-invasive endovascular treatment with detachable platinum coils, such as the
Company's GDC(R) coil, produce better outcomes than neurosurgical clipping for
patients suffering from ruptured brain aneurysms. During 2002, the Company
completed its acquisition of Smart Therapeutics, Inc. ("Smart"), a company that
has developed a stent system for treating "wide neck" aneurysms, which are among
the most difficult to treat. The combination of Smart's stent and the Company's
GDC coil may provide a less-invasive treatment alternative for patients whose
only previous option may have been open surgery.

The Company's next generation Matrix(TM) Detachable Coil features a proprietary
bioabsorbable polymer and leverages technology from the well known, clinically
proven GDC(R) system. The Matrix Detachable Coil has received clearance from the
FDA for endovascular treatment of cerebral aneurysms and was granted the CE Mark
in Europe. This technology is being introduced into selected worldwide markets
in conjunction with physician training programs.

devices. The Company also markets a family of esophageal stents designed to
offer improved dilatation force and greater resistance to tumor in-growth.
During 2002, the Company completed its acquisition of Enteric Medical
Technologies, Inc. ("EMT"), adding EMT's Enteryx(TM) liquid polymer technology,
designed to treat symptoms associated with chronic GERD, to the Company's
portfolio. Currently, the Enteryx product is under Pre-Market Approval (PMA)
review at the FDA, making it the first less-invasive medical device treatment
for GERD to undergo this stringent evaluation. In January 2003, the
Gastroenterology and Urology Device Panel voted unanimously to recommend to the
FDA the approval of the Enteryx product for the treatment of symptoms of GERD in
patients who require and respond to pharmaceutical therapy.

Colorectal Intervention. The Company markets a line of hemostatic catheters,
polypectomy snares, biopsy forceps, enteral stents and dilatation catheters for
the diagnosis and treatment of polyps, inflammatory bowel disease,
diverticulitis and colon cancer.

Pancreatico-Biliary Intervention. The Company sells a variety of products to
diagnose, treat and palliate benign and malignant strictures of the
pancreatico-biliary system (the gall bladder, common bile duct, hepatic duct,
pancreatic duct and the pancreas) and to remove stones found in the common bile
duct. The Company's products include diagnostic catheters used with contrast
media, balloon dilatation catheters and sphincterotomes. The Company also
markets self-expanding metal and temporary biliary stents for palliation and
drainage of the common bile duct.

Pulmonary Intervention. The Company markets devices to diagnose, treat and
palliate diseases of the pulmonary system. The major devices include pulmonary
biopsy forceps, transbronchial aspiration needles, cytology brushes and
tracheobronchial stents used to dilate strictures or for tumor management.
Included in this product offering is the Ultraflex(TM) Tracheobronchial Stent
System and the Wallstent(R) Tracheobronchial Endoprosthesis.

Urinary Tract Intervention and Bladder Disease. The Company sells a variety of
products designed primarily to treat patients with urinary stone disease,
including ureteral dilatation balloons used to dilate strictures or openings for
scope access; stone baskets used to manipulate or remove the stone;
intracorporeal shock wave lithotripsy devices and holmium laser systems used to
disintegrate stones; ureteral stents implanted temporarily in the urinary tract
to provide short-term or long-term drainage; and a wide variety of guidewires
used to gain access to a specific site. The Company has also developed other
devices to diagnose and treat bladder cancer and bladder obstruction.

                                      -13-



Prostate Intervention. For the treatment of Benign Prostatic Hyperplasia
("BPH"), the Company currently markets electro-surgical resection devices
designed to resect large diseased tissue sites and an automatic disposable
needle biopsy system, designed to take rapid core prostate biopsies. In January
2003, the Company announced an alliance with Celsion Corporation to distribute
Celsion's Microfocus BPH 800 Microwave Urethroplasty(TM) system for the
treatment of BPH.

Urinary Incontinence. The Company markets a line of less-invasive devices and
dermal sling materials to treat stress urinary incontinence, an affliction
commonly treated with various surgical procedures. The Company's Precision

less-invasive alternatives for treating incontinence.

Gynecology. In 2002, the Company expanded its product offerings in the area of
women's health through the acquisition of BEI Medical Systems Company, Inc. BEI
designs, manufactures and markets the Hydro ThermAblator(R) (HTA(R)) System, a
less-invasive technology for the treatment of excessive uterine bleeding by
ablating the lining of the uterus, the tissue responsible for menstrual
bleeding.

Oncology Intervention. The Company markets a broad line of products designed to
treat, diagnose and palliate various forms of cancer. Its current suite of
products include a variety of microcatheters, embolic materials, coils and other
products used to restrict blood supply to targeted organs of other areas of the
body as well as biopsy devices. In addition, the Company also markets
radiofrequency based therapeutic devices for the ablation of various forms of
soft tissue lesions (tumors). In 2002, Contour(R) SE Microspheres, a novel
spherical embolization product used to treat hypervascular tumors and
arteriovenous malformations, was launched in the United States. The Contour(R)
SE Microsphere product is designed to shrink and destroy hypervascular tumors
and arteriovenous malformations by blocking the blood supply feeding them.

Central Venous Access. The Company offers a venous access line which includes
valved and non-valved product offerings. The innovative PASV(R) valve technology
is designed to reduce the incidence of occlusion and blood stream infection.

Surgical And Endovascular Grafts. The Company designs vascular grafts and
endovascular stent grafts for the treatment of thoracic dissection, dialysis
access, abdominal aortic aneurysms and peripheral vascular occlusive diseases,
including the Exxcel(TM) vascular graft for peripheral indications and dialysis
access and a line of Hemashield(R) grafts and fabrics for peripheral vascular
and cardiovascular indications. Effective January 1, 2003, this product line was
moved from the Endosurgery business group to the Cardiovascular business group.

                                      -14-




MARKETING AND SALES

During 2002, the Company marketed and sold its products through six divisions.
To best serve its customers, the sales and marketing organizations of these six
divisions were aligned and centralized under two groups, Cardiovascular and
Endosurgery. During 2002, Scimed, EP Technologies and the peripheral vascular
business of Medi-tech operated within the Cardiovascular Group. The Target
Therapeutics division remained a distinct marketing and sales organization
within the Cardiovascular Group. The Medi-tech Surgery/Oncology, Microvasive
Urology and Microvasive Endoscopy businesses operated within the Endosurgery
Group.

In early 2003, Boston Scientific announced a master branding initiative. This
initiative marks the Company's evolution from a collection of divisional
identities into one, unified organization. The master brand will enable the
Company to better focus efforts on strengthening the recognition of the Boston
Scientific name and building equity in that name, as well as conveying the depth
and breadth of the Company, growing the business, recruiting and retaining
strong talent, and ultimately increasing shareholder value.

The Company's tag line: Delivering what's next.(TM)conveys the essence of Boston
Scientific: a committed, forward-looking company executing on its promises and
bringing the latest medical innovations to its customers and their patients.

                                      -15-


Following the launch of the Company's branding initiative later in 2003, the
Company will market its products through nine principal operating businesses,
each focusing upon physicians who specialize in the diagnosis and treatment of
different medical conditions and disease states. An overview of the Company's
2002 divisional and 2003 operating business structure is outlined below.

-----------------------------------------------------------------------------------------------------


A dedicated sales force of approximately 1,200 individuals in over 40 countries
internationally and over 800 in the United States marketed the Company's
products worldwide as of December 31, 2002. Sales in countries where the Company
has direct sales organizations accounted for approximately 99% of the Company's
net sales during 2002. A network of distributors and dealers who offer the
Company's products in more than 35 countries worldwide accounts for the
remaining sales. The Company also has a dedicated corporate sales organization
in the United States focused principally on selling to major buying groups and
large integrated health care networks.

In 2002, the Company sold its products to over 10,000 hospitals, clinics,
out-patient facilities and medical offices. The Company is not dependent on any
single institution and no single institution accounted for more than 10% of the
Company's net sales in 2002. Large group purchasing organizations, hospital
networks and other buying groups have, however, become increasingly important to
the Company's business. The trend toward managed care and economically motivated
and more sophisticated buyers in the United States may result in continued
pressure on selling prices of certain products and resulting compression on
gross margins. These purchasers of medical devices also tend to limit the number
of suppliers from whom they purchase medical

                                      -17-



products. There can be no assurance that these entities will continue to
purchase products from the Company.

The Company also distributes certain products for third parties, including an
introducer sheath and certain guidewires. Together, these distributed products
represented less than 10% of the Company's 2002 net sales. Leveraging its sales
and marketing strength, the Company expects to continue to seek new
opportunities for distributing complementary products as well as new
technologies. The Company expects that it will continue to enter into
distribution arrangements that include options to acquire technology from third
parties at pre-established future dates. These distribution arrangements often
allow the Company to evaluate new technologies prior to acquisition.

INTERNATIONAL OPERATIONS

Internationally, the Company operates through three business segments divided
among the geographic regions of Europe, Japan and Inter-Continental. Maintaining
and expanding its international presence is an important component of the
Company's long-term growth plan. Through its international presence, the Company
seeks to increase net sales and market share, leverage relationships with
leading physicians and their clinical research programs, accelerate the time
within which new products can be brought to market and gain access to worldwide
technological developments that may be implemented across its product lines.

In 2002, international sales accounted for approximately 40% of the Company's
net sales. Net sales, operating income (excluding special charges) and total
assets attributable to significant geographic areas are presented in Note P to
the Company's 2002 Consolidated Financial Statements, which are filed with the
Securities and Exchange Commission as an exhibit to this document.

In recent years, the Company has expanded its direct sales presence worldwide so
as to be in a position to take advantage of expanding market opportunities. As
of December 31, 2002, the Company had direct marketing and sales operations in
over 40 countries internationally. The Company believes that it will continue to
leverage its infrastructure in markets where commercially appropriate and to use
third parties in those smaller markets where it is not economical or strategic
to establish a direct presence.

The Company has four international manufacturing facilities in Ireland.
Presently, approximately 30% of the Company's products sold worldwide are
manufactured at these facilities. The Company also maintains an international
research and development facility in Ireland and a training and research and
development center in Miyazaki, Japan.

The Company's international presence exposes it to certain financial and other
risks. Principal among these is the potentially negative impact of foreign
currency fluctuations on the Company's sales and expenses. Although the Company
engages in nonspeculative hedging transactions that may offset the effect of
fluctuations in foreign currency exchange rates on foreign currency denominated
assets, liabilities, earnings and cash flows, financial exposure may

                                      -18-




nonetheless result, primarily from the timing of transactions, forecast
volatility and the movement of exchange rates. International markets are also
being affected by economic pressure to contain reimbursement levels and health
care costs. The Company's profitability from its international operations may be
limited by risks and uncertainties related to economic conditions in these
regions, regulatory and reimbursement approvals, competitive offerings,
infrastructure development, rights to intellectual property, and the ability of
the Company to implement its overall business strategy. Any significant changes
in the competitive, political, regulatory, reimbursement or economic environment
where the Company conducts international operations may have a material impact
on revenues and profits, especially in Japan, given its high profitability
relative to its contribution to revenues. The Company's Japan business is
expected to be under continued pressure, particularly in the coronary stent
market, due to competitive product offerings and the lack of physician
acceptance of the NIR(R) coronary stent platform. Deterioration in the Japanese
and/or Inter-Continental economies may impact the Company's ability to grow its
business and to collect its accounts receivable in international markets.
Additionally, the trend in countries around the world toward more stringent
regulatory requirements for product clearance, changing reimbursement models and
more vigorous enforcement activities has generally caused or may cause medical
device manufacturers to experience more uncertainty, greater risk and higher
expenses.

MANUFACTURING; RAW MATERIALS

The Company designs and manufactures the majority of its products in twenty
technology centers around the world. During 2000, the Company approved and
committed to a global operations plan consisting of a series of strategic
initiatives designed to increase productivity and enhance innovation. The plan
includes manufacturing process and supply chain programs and a plant
optimization initiative. During the second quarter of 2002, the Company
substantially completed its plant optimization initiative. The plant
optimization initiative has created a better allocation of the Company's
resources by forming a more effective network of manufacturing and research and
development facilities. The Company's plan resulted in the consolidation of
manufacturing operations along product lines and the shifting of significant
amounts of production to the Company's facilities in Miami and Ireland and to
contract manufacturing. The Company's plan included the discontinuation of
manufacturing activities at three facilities in the United States, and included
the planned displacement of approximately 1,950 manufacturing, manufacturing
support and management employees.

Most components used in the manufacture of the Company's products are readily
fabricated from commonly available raw materials or off-the-shelf items
available from multiple supply sources. The fabricated items are custom made for
the Company to meet its specifications. The Company believes that in most cases,
redundant capacity exists at the suppliers and that alternative sources of
supply are available or could be developed within a reasonable period of time.
Generally, the Company has been able to obtain adequate supplies of raw
materials and components in a timely manner from established sources. In certain
cases, the Company may not be able to quickly establish additional or
replacement suppliers for specific components or materials, largely due to the
FDA approval system and other regulatory requirements and the complex nature of
the manufacturing processes employed by the Company and many suppliers.

                                      -19-



The reduction or interruption in supply, an inability to develop and validate
alternative sources if required, or a significant increase in the price of raw
materials or components could adversely affect the Company's operations and
financial condition.

QUALITY ASSURANCE

The Company is committed to providing high quality products to its customers. To
meet this commitment, the Company has implemented state-of-the-art quality
systems and concepts throughout the organization. The Company's quality system
starts with the initial product specification and continues through the design
of the product, component specification process and the manufacturing, sales and
servicing of the product. The quality system is designed to build in quality and
to utilize continuous improvement concepts throughout the product life. These
systems enable the Company to satisfy the quality system regulations of the FDA
with respect to products sold the United States. Many of the Company's
operations are certified under ISO 9001, ISO 9002, ISO 13485, ISO 13488, EN46001
and EN46002 international quality system standards. ISO 9002 requires, among
other items, an implemented quality system that applies to component quality,
supplier control and manufacturing operations. In addition, ISO 9001 and EN46001
require an implemented quality system that applies to product design. These
certifications can be obtained only after a complete audit of a company's
quality system by an independent outside auditor. Maintenance of these
certifications requires that these facilities undergo periodic reexamination.
During 2002, the Company established an initiative to seek ISO 14001
certification at various plants around the world. The ISO 14001, a standard in
the ISO 14000 series, provides a voluntary approach regarding environmental
management systems that helps organizations assure positive environmental
performance. This initiative will continue until our facilities become
certified. In March 2003, the Company received corporate certification to
ISO 9001, MDD and EN 46001 standards.

COMPETITION

The Company encounters significant competition across its product lines and in
each market in which its products are sold from various entities, some of which
may have greater financial and marketing resources than the Company. The
Company's primary competitors include: Abbott Laboratories, Inc., C.R. Bard,
Inc., Cook, Inc., Guidant Corporation (including its subsidiary Advanced
Cardiovascular Systems, Inc.), Johnson & Johnson (including its subsidiary,
Cordis Corporation), Medtronic, Inc. (including its subsidiary, Medtronic AVE,
Inc.) and Tyco International, as well as a wide range of companies which sell a
single or limited number of competitive products or participate only in specific
market segment. In addition, the worldwide coronary stent market is dynamic and
highly competitive, with significant market share volatility. Technology and
competitive offerings, particularly a competitor's prior entry in the
drug-eluting stent market, may negatively impact the Company's revenues. The
Company also faces competition from non-medical device companies, such as
pharmaceutical companies, which may offer non-surgical alternative therapies for
disease states which are currently or intended to be treated using the Company's
products.

                                      -20-



The Company believes that its products compete primarily on the basis of their
ability to safely and effectively perform diagnostic and therapeutic procedures
in a less-invasive manner, ease of product use, product reliability and
physician familiarity. In the current environment of managed care, economically
motivated buyers, consolidation among health care providers, increased
competition and declining reimbursement rates, the Company has also been
increasingly required to compete on the basis of price, value and efficiency.
The Company believes that its continued competitive success will depend upon its
ability to create or acquire scientifically advanced technology, apply its
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 its products, obtain required regulatory and
reimbursement approvals, manufacture and successfully market its products either
directly or through outside parties and supply sufficient inventory to meet
customer demand.

RESEARCH AND DEVELOPMENT

Enhancements of existing products or expansions of existing product lines, which
are typically developed within the Company's manufacturing and marketing
operations, contribute to each year's sales growth. The Company believes that
streamlining, prioritization and coordination of its technology pipeline and new
product development activities are essential to its ability to stimulate growth
and maintain leadership positions in its markets. By centralizing platform
technology development at the corporate level, the Company is able to pursue
technologies that can be leveraged across multiple markets. The Company's
approach to new product design and development is through focused, cross
functional efforts. The Company believes that its formal process for technology
and product development aids in its ability to offer innovative and
manufacturable products in a consistent and timely manner. Involvement of the
R&D, clinical, quality, regulatory, manufacturing and marketing teams early in
the process is the cornerstone of a product development cycle. This
collaboration allows the team to concentrate resources on the most viable and
profitable new products and technologies and get them to market in a timely
manner.

                                      -21-



In 2002, the Company expended approximately $343 million on research and
development, representing approximately 12 percent of the Company's 2002 net
sales. The investment in research and development dollars reflects spending on
new product development programs as well as regulatory compliance and clinical
research. The increase in research and development expense from 2001 levels is
primarily due to investment in the development of, and clinical trials related
to, the Company's TAXUS(TM) drug-eluting stent program and to investment in
development programs acquired in connection with the Company's business
combinations. The Company currently anticipates research and development
expenses as a percentage of net sales to remain at approximately 12 percent in
2003. There can be no assurance, however, that the Company's performance will
not be affected by management's decisions relating to investments in research
and development at anticipated levels during 2003.

In addition to internal development, the Company works with hundreds of leading
research institutions, universities and clinicians around the world in
developing, evaluating and clinically testing its products. The Company believes
its future success will depend upon the strength of its development efforts.
There can be no assurance that the Company will realize financial benefit from
its development programs, will continue to be successful in identifying,
developing and marketing new products or enhancing its existing products, or
that products or technologies developed by others will not render the Company's
products or technologies non-competitive or obsolete.

REGULATION

The medical devices manufactured and marketed by the Company are subject to
regulation by numerous regulatory bodies, including the FDA and comparable
international regulatory agencies. These agencies require manufacturers of
medical devices to comply with applicable laws and regulations governing the
development, testing, manufacturing, labeling, marketing and distribution of
medical devices. Devices are generally subject to varying levels of regulatory
control, the most comprehensive of which requires that a clinical evaluation
program be conducted before a device receives approval for commercial
distribution.

In the United States, permission to distribute a new device generally can be met
in one of two ways. The first process requires that a pre-market notification
(the "510(k) Submission") be made to FDA to demonstrate that the device is as
safe and effective, that is, substantially equivalent to a legally marketed
device that is not subject to pre-market approval ("PMA"). Applicants must
compare this device to one or more similar devices commercially available in the
United States and make and support their substantial equivalency claims. A
legally marketed device is a device that (i) was legally marketed prior to May
28, 1976, (ii) has been reclassified from Class III to Class II or I, or (iii)
has been found to be substantially equivalent to a device following a 510(k)
Submission. The legally marketed device(s) to which equivalence is drawn is
known as the "predicate" device(s). Applicants must submit descriptive data and,
when necessary, performance data to establish that the device is substantially
equivalent to a predicate device. In some instances, data from human clinical
trials must also be submitted in support of a

                                      -22-



510(k) Submission. If so, these data must be collected in a manner that conforms
with specific requirements in accordance with federal regulations. The FDA must
issue an order finding substantial equivalence before commercial distribution
can occur.

Changes to existing devices covered by a 510(k) Submission which do not
significantly affect safety or effectiveness can generally be made by the
Company without additional 510(k) Submissions.

The second process requires that an application for PMA be made to the FDA to
demonstrate that the device is safe and effective for its intended use as
manufactured. This approval process applies to certain Class III devices. In
this case, two steps of FDA approval are generally required before marketing in
the United States can begin. First, the Company must comply with investigational
device exemptions ("IDE") regulations in connection with any human clinical
investigation of the device in the United States. Second, the FDA must review
the Company's PMA application which contains, among other things, clinical
information acquired under the IDE. The FDA will approve the PMA application if
it finds that there is a reasonable assurance that the device is safe and
effective for its intended purpose.

The FDA can ban certain medical devices, detain or seize adulterated or
misbranded medical devices, order repair, replacement or refund of these
devices, and require notification of health professionals and others with regard
to medical devices that present unreasonable risks of substantial harm to the
public health. The FDA may also enjoin and restrain certain violations of the
Food, Drug and Cosmetic Act and the Safe Medical Devices Act pertaining to
medical devices, or initiate action for criminal prosecution of such violations.
International sales of medical devices manufactured in the United States that
are not approved by the FDA for use in the United States, or are banned or
deviate from lawful performance standards, are subject to FDA export
requirements. The Export Reform Act of 1996 has simplified the process of
exporting devices which have not been approved for sale in the United States.

Exported devices are subject to the regulatory requirements of each country to
which the device is exported. Some countries do not have medical device
regulations, but in most foreign countries medical devices are regulated. In
many of these countries the medical device regulations are similar to drug
regulations. The majority of the Company's products are expected to be so
regulated in these countries. Frequently, regulatory approval may first be
obtained in a foreign country prior to application in the United States to take
advantage of differing regulatory requirements. The Company has completed CE
Mark registrations for substantially all of its products in accordance with the
implementation of various medical device directives in the European Union.

The process of obtaining clearance to market products is costly and
time-consuming in virtually all of the major markets in which the Company sells
products and can delay the marketing and sale of new products. Countries around
the world have recently adopted more stringent regulatory requirements which are
expected to add to the delays and uncertainties associated with new product
releases, as well as the clinical and regulatory costs of supporting such
releases. No assurance can be given that any of the Company's new medical
devices will be

                                      -23-



approved on a timely basis, if at all. In addition, regulations regarding the
development, manufacture and sale of medical devices are subject to future
change. The Company cannot predict what impact, if any, such changes might have
on its business. Failure to comply with regulatory requirements could have a
material adverse effect on the Company's business, financial condition and
results of operations.

The Company is also subject to environmental laws and regulations both in the
United States and abroad. The operations of the Company, like those of other
medical device companies, involve the use of substances regulated under
environmental laws, primarily in manufacturing and sterilization processes. The
Company believes that compliance with environmental laws will not have a
material impact on its financial position, results of operations, or liquidity.
Given the scope and nature of these laws, there can, however, be no assurance
that environmental laws will not have a material impact on the Company.

                                      -24-



THIRD-PARTY COVERAGE AND REIMBURSEMENT

The Company's products are purchased by hospitals, doctors and other health care
providers who are reimbursed for the health care services provided to their
patients by third-party payors, such as governmental programs (e.g., Medicare
and Medicaid), private insurance plans and managed care programs. Third party
payors may provide or deny coverage for certain technologies and associated
procedures based on assessment criteria as determined by the third-party payor.
Reimbursement by third-party payors for these services is based on a wide range
of methodologies that may reflect the services' assessed resource costs,
clinical and economic value. These reimbursement methodologies confer different,
and often conflicting, levels of financial risk and incentives to health care
providers and patients, and these methodologies are subject to frequent
refinements. Third party payers are also increasingly adjusting reimbursement
rates and challenging the prices charged for medical products and services.
There can be no assurance that the Company's products will be automatically
covered by third-party payors, that reimbursement will be available or, if
available, that the third-party payors' coverage policies will not adversely
affect the Company's ability to sell its products profitably.

Initiatives to limit the growth of healthcare costs, including price regulation,
are also underway in many countries in which the Company does business.
Implementation of healthcare reforms in significant markets such as Japan,
Europe, and other countries may limit the price of, or the level at which
reimbursement is provided for, the Company's products and may influence a
physician's selection of products used to treat patients.

PROPRIETARY RIGHTS AND PATENT LITIGATION

The Company relies on a combination of patents, trademarks, trade secrets and
non-disclosure agreements to protect its intellectual property. The Company
generally files patent applications in the United States and foreign countries
where patent protection for its technology is appropriate and available. The
Company holds more than 2,800 United States patents (many of which have foreign
counterparts) and has more than 4,600 patent applications pending worldwide that
cover various aspects of its technology. In addition, the Company holds
exclusive and non-exclusive licenses to a variety of third party technologies
covered by patents and patent applications. There can be no assurance that
pending patent applications will result in issued patents, that patents issued
to or licensed by the Company will not be challenged or circumvented by
competitors, or that such patents will be found to be valid or sufficiently
broad to protect the Company's technology or to provide the Company with a
competitive advantage.

The Company relies on non-disclosure and non-competition agreements with
employees, consultants and other parties to protect, in part, trade secrets and
other proprietary technology. There can be no assurance that these agreements
will not be breached, that the Company will have adequate remedies for any
breach, that others will not independently develop equivalent proprietary
information or that third parties will not otherwise gain access to the
Company's trade secrets and proprietary knowledge.

                                      -25-



There has been substantial litigation regarding patent and other intellectual
property rights in the medical device industry, particularly in the areas in
which the Company competes. The Company has defended, and will likely continue
to defend, itself against claims and legal actions alleging infringement of the
patent rights of others. Adverse determinations in any patent litigation could
subject the Company to significant liabilities to third parties, require the
Company to seek licenses from third parties, and, if licenses are not available,
prevent the Company from manufacturing, selling or using certain of its
products, some of which could have a material adverse effect on the Company.

Additionally, the Company may find it necessary to initiate litigation to
enforce its patent rights, to protect its trade secrets or know-how and to
determine the scope and validity of the proprietary rights of others. Patent
litigation can be costly and time-consuming, and there can be no assurance that
the Company's litigation expenses will not be significant in the future or that
the outcome of litigation will be favorable to the Company. Accordingly, the
Company may seek to settle some or all of its pending litigation. Settlement may
include cross-licensing of the patents which are the subject of the litigation
as well as other intellectual property of the Company and may involve monetary
payments to or from third parties.

OTHER LITIGATION AND RISK MANAGEMENT

The testing, marketing and sale of human health care products entails an
inherent risk of product liability claims. The Company is involved in various
lawsuits arising in the normal course of business from product liability claims,
and product liability claims may be asserted in the future relative to events
not known to management at the present time. As a result of current economic
factors impacting the insurance industry, at the beginning of the third quarter
of 2002, the Company elected to become substantially self-insured with respect
to general and product liability claims. Losses for claims in excess of the
limits of purchased insurance would be recorded at the time and to the extent
they are probable and estimable. Management believes that the Company's risk
management practices, including limited insurance coverage, are reasonably
adequate to protect against anticipated general and product liability losses.
However, unanticipated catastrophic losses could have a material adverse impact
on the Company's financial position, results of operations and liquidity.

See the "Legal Proceedings" section below and Note L - Commitments and
Contingencies to the Company's 2002 Consolidated Financial Statements (Exhibit
13.1 filed herewith) for a further discussion of patent and other litigation and
proceedings involving the Company.

EMPLOYEES

As of December 31, 2002, the Company had approximately 13,900 employees,
including more than 7,800 in operations, 1,400 in administration, 1,400 in
clinical and research and development and 3,200 in selling, marketing,
distribution and related administrative support. Of these employees,
approximately 2,100 were employed in the Company's international operations. The
Company believes that the continued success of its business will depend, in
part, on its ability to attract and retain qualified personnel.

                                      -26-



SEASONALITY

Worldwide sales do not reflect any significant degree of seasonality, however
customer purchases have been lighter in the third quarter of prior years than in
other quarters. This reflects, among other factors, lower demand during summer
months, particularly in European countries.

RECENT PATENT LITIGATION ACTIVITY

Litigation with Johnson & Johnson

On March 13, 2002, the Company and Boston Scientific Scimed, Inc. filed suit for
patent infringement against the Johnson & Johnson and Cordis Corporation
(Cordis), a subsidiary of Johnson & Johnson, alleging that its Cypher(TM)
drug-eluting stent infringes a patent owned by the Company. The suit was filed
in the District Court of Delaware seeking monetary and injunctive. On March 20,
2003, the Company filed a motion seeking a preliminary injunction with respect
to the sale of the Cypher stent in the United States.

On January 13, 2003, Cordis filed suit for patent infringement against the
Company and Scimed Life Systems, Inc. (SCIMED) alleging the Company's
Express(2)(TM) coronary stent is infringed by a U.S. patent owned by Cordis. The
suit was filed in the U.S. District Court for the District of Delaware seeking
monetary and injunctive relief. On February 14, 2003, Cordis filed a motion
