ITEM 1.  BUSINESS

THE COMPANY

Boston Scientific Corporation (the "Company") is a worldwide developer,
manufacturer and marketer of minimally invasive medical devices. The Company's
products are used in a broad range of interventional medical specialties,
including cardiology, electrophysiology, gastroenterology, neuro-endovascular
therapy, pulmonary medicine, radiology, urology and vascular surgery. 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 procedural
trauma, complexity, risk to the patient, cost and recovery time.

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 minimally 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 $2.2 billion in 1998.

The Company's growth in the past few years has been fueled in part by strategic
acquisitions and alliances, designed to improve the ability of the Company to
take advantage of future growth opportunities in less invasive medicine. In
1998, the Company completed two acquisitions. On June 30, 1998, the Company
acquired CardioGene Therapeutics, Inc., a development stage company focused on
the application of gene therapy for treatment of cardiovascular diseases, and on
September 10, 1998, the Company acquired Schneider Worldwide, a pioneer in less
invasive medicine and formerly a member of the Medical Technology Group of
Pfizer Inc.

These acquisitions, together with the Company's earlier acquisitions and
alliances, have helped to achieve a strategic mass which allows the Company to
offer one of the broadest product lines in the world for use in minimally
invasive procedures. The Company now maintains leadership positions in each of
the markets in which it competes. The Company's strategic mass has also enabled
it to compete more effectively in, and better absorb the pressures of, the
current healthcare environment of cost containment, managed care, large buying
groups and hospital consolidations.


                                       3
<PAGE>   4

The Company has substantially completed the integration of all mergers and
acquisitions consummated in 1996 and 1997. The Company expects to complete the
integration of Schneider by the end of 1999. Management believes it has
developed a sound plan for continuing and concluding the integration process,
and that it will achieve that plan. However, in view of the number of major
transactions undertaken by the Company, the dramatic change in the size of the
Company and the complexity of its organization resulting from these
transactions, management also believes that the successful implementation of its
plan presents a significant degree of difficulty. The failure to integrate these
businesses effectively could adversely affect the Company's operating results in
the near term, and could impair the Company's ability to realize the strategic
and financial objectives of these transactions.

BUSINESS STRATEGY

The Company's mission is to improve the quality of patient care and the
productivity of healthcare delivery through the development and advocacy of
minimally invasive medical devices and procedures. The Company seeks to
accomplish this mission through the continuing refinement of existing products
and procedures and the investigation and development, as well as the
acquisition, of new technologies which can reduce risk, trauma, cost, procedure
time and the need for aftercare. The Company's strategy has been, and will
continue to be, to grow by identifying those specific therapeutic and diagnostic
areas which satisfy the Company's mission and provide attractive opportunities
for long-term growth and by making the investments necessary to capitalize on
these opportunities. Key elements of this strategy are as follows:

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 vascular and nonvascular procedures. The breadth and diversity
of the Company's product lines permit medical specialists to satisfy many of
their minimally invasive medical device requirements from a single source. The
scope of its products and markets also reduces the Company's vulnerability to
change in the competitive, regulatory and technological environments for any
single product or market.

Product Innovation. The Company maintains an aggressive product development
program designed to introduce new products and new applications for existing
technologies on a regular basis. The specifications and features of new products
are often developed from market information generated through the interaction of
the Company's product management teams and sales representatives with the
worldwide medical community. The Company seeks to expedite the design and
development of new products by leveraging its proprietary core technologies and
applications knowledge across its product lines. Technological innovations
developed for a particular application are often applied to procedures used in
other markets served by the Company.


                                       4
<PAGE>   5

Focused Marketing. The Company markets its products through six principal
divisions: Scimed, EP Technologies, Boston Scientific Vascular (formerly
operating as Medi-tech, Meadox and Schneider), Target Therapeutics, Microvasive
Endoscopy and Microvasive Urology. Each of the Company's divisions focuses on
physicians who specialize in the diagnosis and treatment of different medical
conditions and offers products to satisfy their needs. The Company believes that
this focused marketing approach enables it to develop highly knowledgeable and
dedicated sales representatives and to foster close professional relationships
with physicians.

International Presence. Maintaining and expanding its international presence is
an important component of the Company's long term growth plan. In 1998,
international sales accounted for approximately 38% of the Company's net sales.
Currently, the Company operates three international manufacturing facilities in
Ireland and one in Switzerland, has direct marketing and sales subsidiaries in
more than 35 countries and has distribution arrangements in more than 45
countries. Through its international presence, the Company seeks to increase net
sales and market share, 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.

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. The Company enhances its presence in the medical
community through active participation in medical meetings, by conducting
comprehensive training and educational activities and through employee-authored
articles in medical journals and textbooks. Each year, numerous scientific
papers are published and presentations are made describing clinical applications
of the Company's products. The Company believes that these activities and its
advocacy positions contribute to the medical community's understanding and
adoption of minimally invasive techniques and the expansion of these techniques
into new therapeutic and diagnostic areas.

Corporate Culture. Management believes that success and leadership evolves 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 maintaining the values on which its success has been
based.

Strategic Acquisitions and Alliances. In recent years, the Company has sought
out strategic acquisitions, alliances and venture opportunities which complement
or expand its existing product lines or enhance its technological position.
Although the Company does not expect to make any significant acquisitions in
1999, the Company expects that it will continue to seek out and review
opportunities for acquisitions and strategic alliances consistent with its
corporate mission.

PRODUCTS

The Company's products are broadly categorized as vascular or nonvascular,
depending on the anatomical system and procedure in which a product is intended
to be used. Generally, vascular products are employed in procedures affecting
the heart and systems which carry blood, and nonvascular products are employed
in procedures affecting other systems and organs. In 1998, approximately 80% of
the Company's net sales were derived from its vascular business, approximately
19% from its nonvascular business and approximately 1% from other business. The
Company's principal vascular and nonvascular products are offered in the
following medical areas:

                                    VASCULAR

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. Atherosclerosis results in
reduced blood flow to the muscle of the heart. The majority of the Company's
products in this market are used in percutaneous transluminal coronary
angioplasty ("PTCA") and percutaneous transluminal coronary rotational
atherectomy ("PTCRA"). The Company's products in this market include PTCA
balloon catheters, the Rotablator(R) rotational atherectomy system, guide wires,
guide catheters, diagnostic catheters and fluid management systems.

Coronary Stents. The Company markets both balloon-expandable and self-expanding
coronary stent systems. The Company's most important products in this category
incorporate the NIR(R) balloon-expandable coronary stent developed and
manufactured by Medinol Ltd., with which the Company has an exclusive worldwide
distribution agreement for stent products. These products were introduced in
Europe in 1996 and in the United States and Japan in 1998. The Company hopes to
introduce the NIR ON(TM) VIVA!(TM) stent using Monorail(TM) rapid exchange
technology in the United States in 1999, pending approval from the United States
Food and Drug Administration ("FDA"). The Company also hopes to reintroduce the
NIR ON(TM) Ranger(TM) with SOX(TM) stent delivery system in the United States
later in 1999, pending FDA approval. Through a strategic alliance with Angiotech
Pharmaceuticals, Inc., the Company holds a co-exclusive license for the use of
paclitaxel on intraluminal devices to inhibit restenosis.

Peripheral Vascular Intervention and Vascular Access. 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 catheters used in percutaneous transluminal angioplasty ("PTA").
Additionally, the Company's peripheral vascular product line includes medical
devices used in thrombolysis (the catheter-based delivery of clot dissolving
agents directly to the site of a blood clot) and thrombectomy catheters. The
Company also offers stents to maintain patency of peripheral lumens, including
the WALLSTENT(R) endoprosthesis, the only stent approved by the FDA for more
than two peripheral indications.


                                       6
<PAGE>   7

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.

Surgical and Endovascular Grafts. The Company markets vascular grafts and
endovascular stent grafts for the treatment of thoracic dissection, abdominal
aortic aneurysms and peripheral vascular occlusive diseases.

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

Electrophysiology ("EP"). The Company's electrophysiology product offerings
include catheters and systems for use in minimally invasive procedures to
diagnose and treat tachyarrhythmias (abnormally fast heart rhythms). The Company
markets RF generators 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.

Neuro-Endovascular Therapy. 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 Guglielmi Detachable Coil(TM)
system to treat and prevent the rupture of cerebral aneurysms that are otherwise
either considered to be inoperable or high risk for surgery.

                                   NONVASCULAR

Esophageal, Gastric and Duodenal Intervention. The Company markets a broad range
of products to diagnose, treat and palliate a variety of esophageal, gastric and
duodenal diseases, including esophogitis, gastric esophageal reflux disease,
portal hypertension, peptic ulcers and esophageal cancer. The Company's products
in this area include disposable single and multiple biopsy forceps, balloon
dilatation catheters, banding ligation devices and enteral feeding devices. The
Company also markets a family of esophogeal stents designed to offer improved
dilatation force and greater resistance to tumor in-growth.

Colorectal Intervention. The Company markets a line of hemostatic catheters,
polypectomy snares 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
and hepatic ducts. The Company's products include diagnostic catheters used with
contrast media, balloon dilatation catheters and sphincterotomes. The Company
also markets a temporary biliary stent for palliation and drainage of the common
bile duct.


                                       7
<PAGE>   8

Pulmonary Intervention. The Company markets devices to diagnose, treat and
palliate chronic bronchitis and lung cancer, including pulmonary biopsy forceps
and balloon catheters used to dilate strictures or for tumor management.

Urinary Tract Intervention. The Company sells a variety of products designed
primarily to treat patients with urinary stone disease, either via ureteroscopy
or percutaneous nephrolithotomy. Products within this category include ureteral
dilatation balloons used to dilate strictures or openings for scope access;
stone baskets used to manipulate, crush, or remove the stone; intracorporeal
shock wave lithotripsy devices and holmium laser systems used to disintegrate
stones ureteroscopically; ureteral stents implanted temporarily in the urinary
tract to provide either short-term or long-term drainage; and a wide variety of
guidewires used to gain access to a specific site.

Prostate Intervention. For the treatment of Benign Prostatic Hypertrophy
("BPH"), the Company currently markets electro-surgical resection devices
designed to resect large diseased tissue sites and reduce the bleeding
attributable to the resection procedure (a major cause of patient morbidity in
connection with traditional surgical treatments for BPH) and an automatic
disposable needle biopsy system, designed to take rapid core prostate biopsies.

Urinary Incontinence and Bladder Disease. The Company markets a line of
minimally invasive devices and sling materials to treat stress urinary
incontinence. This affliction is commonly treated with various surgical
procedures. The Company's Vesica(R) system offers less invasive alternatives for
treating incontinence. The Company has also developed other devices to diagnose
and treat bladder cancer and bladder obstruction.

INTERNATIONAL OPERATIONS

In 1998, international sales accounted for approximately 38% of the Company's
net sales. Net sales, operating income and identifiable assets attributable to
significant geographic areas are presented in Note N to the Company's 1998
Consolidated Financial Statements, included within the Company's 1998 Annual
Report to Shareholders which is filed with the Securities and Exchange
Commission as an exhibit hereto.

As of December 31, 1998, the Company had direct marketing and sales operations
in more than 35 countries. During the past three years, the Company has expanded
its direct sales presence in Europe and Emerging Markets so as to be in a
position to take advantage of market opportunities in those regions. The Company
believes that, during 1999, it will continue to leverage its direct sales
infrastructure and will continue to use distributors in those smaller markets
where it is not economical or strategic to establish a direct presence.

The Company has three international manufacturing facilities in Ireland and one
in Switzerland. Presently, approximately 50% of the Company's products sold
internationally are manufactured at these facilities. The Company also maintains
an international research and development facility in Galway, Ireland and a
training center in Miyazaki, Japan.


                                       8
<PAGE>   9

The Company's expanded 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 hedging transactions that may offset the effect of
fluctuations in foreign currency exchange rates on foreign currency denominated
assets and liabilities, financial exposure may nonetheless result, primarily
from the timing of transactions and the movement of exchange rates. As the
Company has expanded its international operations, its sales and expenses
denominated in foreign currencies have expanded and that trend is expected to
continue. Therefore, most international sales and expenses have been, and are
expected to be, subject to the effect of foreign currency fluctuations and these
fluctuations may have an impact on margins. Further, any significant changes in
the political, regulatory or economic environment where the Company conducts
international operations could have a material impact on revenues and profits.

MARKETING AND SALES

The Company markets its products through six principal divisions, each focusing
upon physicians who specialize in the diagnosis and treatment of different
medical conditions.

VASCULAR

                            flexible endoscopic procedures involving the        
                            digestive tract and lungs.                          

     Microvasive            offers a line of therapeutic and diagnostic devices 
     Urology:               which aid urologists in performing ureteroscopic and
                            other minimally invasive endoscopic procedures as   
                            well as devices to treat urinary incontinence.      

A dedicated sales force of in excess of 1900 individuals, including over 800 in
the United States, markets the Company's products worldwide. This dedicated
sales force accounted for approximately 99% of the Company's net sales during
1998. A network of over 70 dealers who offer the Company's products in more than
45 countries worldwide accounts for the remaining sales. The Company has also
established a dedicated U.S. corporate sales organization focused principally on
selling to major buying groups and large integrated healthcare networks.

The Company's worldwide customer base includes interventional medical
specialists, including cardiologists, radiologists, neuroradiologists,
neurosurgeons, gastroenterologists, urologists, electrophysiologists,
pulmonologists, vascular surgeons and gynecologists. In 1998, 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
1998. Large group purchasing organizations, hospital networks and other buying
groups are, however, becoming increasingly important to the Company's business.
These organizations have exerted increased pressure on selling prices throughout
the medical device industry. There can be no assurance that the impact of doing
business with such organizations will not adversely impact future Company sales
margins, or that such organizations will continue to do business with the
Company.

The Company markets the NIR ON(TM) Ranger(TM) and NIR(R) Primo(TM) coronary
stent systems which, together with other NIR(R) stent systems, represented
approximately 13% of the Company's 1998 worldwide sales. These stent systems
include the NIR(R) coronary stent which is developed and manufactured by Medinol
Ltd. and a balloon delivery system which is developed and manufactured by the
Company. The Company also distributes several other products for third parties,
including RF generators, an introducer sheath and certain guidewires. None of
these other products represented more than 10% of the Company's 1998 net sales.
Leveraging its sales and marketing strength, the Company expects to continue to
seek out new opportunities for distributing complementary products as well as
new technologies. Certain of the products distributed by the Company, such as
the NIR(R) stent, are very important to the Company strategically. Unforeseen
delays, stoppages or interruptions in the supply and/or mix of the NIR(R) stent
or certain other distributed products could adversely affect the Company's
operating results.

Uncertainty remains with regard to future changes within the healthcare
industry. The trend towards managed care and economically motivated buyers in
the United States may result in continued pressure on selling prices of certain
products and resulting compression on gross

margins. The United States marketplace is also increasingly characterized by
consolidation among healthcare providers and purchasers of medical devices who
prefer to limit the number of suppliers from whom they purchase medical
products. There can be no assurance that these entities will continue to
purchase products from the Company. In addition, international markets are also
being affected by economic pressure to contain healthcare costs. Throughout the
world, delays in product approval processes, changes in reimbursement policies
and competitive pricing pressures remain unpredictable. The Company cannot
predict what future economic, reimbursement and pricing environments will exist
in domestic and international markets for its healthcare products. It is
possible that such environments could adversely affect the Company's product
pricing and ability to sell products. The Company believes that such factors
will continue to impact the rate at which the Company can grow, but management
believes that it is well positioned to take advantage of opportunities for
growth that exist in the markets it serves.

MANUFACTURING; RAW MATERIALS

The Company designs and manufactures the majority of its products in 16
manufacturing sites around the world. The majority of the raw materials used in
the manufacture of the Company's products are off-the-shelf items readily
available from several supply sources. Several items are, however, custom made
for the Company to meet its specifications. The Company believes that, in most
of these cases, redundant capacity exists at the supplier and that alternative
sources of supply are available or could be developed within a reasonable period
of time. The Company has generally been able to obtain adequate supplies of all
materials, parts and components in a timely manner from existing sources.
However, the inability to develop alternative sources, if required, or a
reduction or interruption in supply or a significant increase in the price of
materials, parts or components could adversely affect the Company's operations
and financial condition.

During 1998, the Company initiated a full time global program to focus on supply
chain optimization. The program is designed to lower inventory levels and the
cost of manufacturing, improve absorption, enhance customer service levels and
minimize inventory write-downs. By addressing the entire supply chain, including
application of lean manufacturing techniques, the Company seeks to return gross
margins to more acceptable levels and to improve working capital. The program
should be implemented by the end of 1999.

COMPETITION

The Company encounters significant competition from various entities across its
product lines and in each market in which its products are sold. The Company's
primary competitors include C.R. Bard, Inc., Cook, Inc., Guidant Corporation,
Johnson & Johnson (including its subsidiary, Cordis Corporation), and Medtronic,
Inc. (including its subsidiary, Medtronic AVE, Inc., formerly known as Arterial
Vascular Engineering Inc.), as well as a wide range of companies which sell a
single or limited number of competitive products.

In addition, the Company faces competition from non-medical device companies,
such as pharmaceutical companies, which may offer non-surgical alternative
therapies for disease states which are currently treated using the Company's
products.


                                       11
<PAGE>   12

The Company believes that its products compete primarily on the basis of their
ability to perform safely and effectively diagnostic and therapeutic procedures
in a minimally 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. 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
approvals, and manufacture and successfully market its products either directly
or through outside parties. There can be no assurance that the Company will be
able to accomplish these objectives or that it will be able to compete
successfully in the future against existing or new competitors. There can also
be no assurance that the Company's operating results will not be adversely
affected by increased price competition or competition from purveyors of
alternative therapies.

RESEARCH AND DEVELOPMENT

The Company maintains an active program of new product and technology research
and development. By leveraging the technical and applications knowledge gained
in one medical specialty to other specialties, the Company believes that its
product development process is accelerated and made more cost effective.
Enhancements of existing products or expansions of existing product lines, which
are typically developed within the Company's manufacturing and marketing
operations, account for a significant portion of each year's sales growth.

In 1998, the Company expended $200 million on research and development,
representing approximately 9% of the Company's 1998 net sales. These
expenditures funded clinical research, licensed technology, regulatory
activities and various product development programs, including, without
limitation, carotid stenting, molecular intervention technology (using
paclitaxel, radiation, angiogenesis technology and gene therapy) and stent
grafting.

The Company maintains several research and development facilities around the
globe. See "Properties". 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
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, less rigorous, process applies to any new device
that is substantially equivalent to a device first marketed prior to May 1976
and does not require pre-market approval ("PMA"). In this case, FDA permission
to distribute the device can be accomplished by submission of a pre-market
notification submission (a "510(k) Submission"), and issuance by the FDA of an
order permitting commercial distribution. A 510(k) Submission must provide
information supporting its claim of substantial equivalence. If clinical data
from human experience is required to support a 510(k) Submission, this data must
be gathered in compliance with investigational device exemption ("IDE")
regulations for investigations performed in the United States. The FDA must
issue an order finding substantial equivalence before commercial distribution
can occur. Changes to existing devices which do not significantly affect safety
or effectiveness can generally be made by the Company without additional 510(k)
Submissions.

The second, more comprehensive, approval process applies to a new device that is
not substantially equivalent to an existing product. 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 IDE regulations in connection with
any 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. In many foreign countries, all regulated medical
products are treated as drugs and the majority of 


                                       13
<PAGE>   14

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 achieved International Standards Organization or
European Union certification for its Irish and most of its United States
manufacturing facilities. In addition, the Company has completed CE Mark
registrations for most 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 approved on a timely basis, if at all.

In addition, regulations regarding the 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 such laws will not have a material impact
on its financial position, results of operations, or liquidity. Given the scope
and nature of such laws, there can, however, be no assurance that such laws will
not have a material impact on the Company.

THIRD-PARTY 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. These
third-party payors may deny reimbursement if they should determine that a device
used in a procedure was not used in accordance with cost-effective treatment
methods, as determined by such third-party payor, or was used for an unapproved
indication. Also, third-party payors are increasingly challenging the prices
charged for medical products and services. There can be no assurance that the
Company's products will be considered cost-effective by third-party payors, that
reimbursement will be available or, if available, that the third-party payors'
reimbursement policies will not adversely affect the Company's ability to sell
its products profitably.


                                       14
<PAGE>   15

PATENTS AND PROPRIETARY RIGHTS

The Company relies on a combination of patents, trade secrets and non-disclosure
agreements to protect its intellectual property. The Company holds in excess of
1,000 patents in the United States and abroad and has pending in excess of 2,500
patent applications 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 patents 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 certain 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.

There has been substantial litigation regarding patent and other intellectual
property rights in the medical device industry generally, 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 such
litigation could subject the Company to significant liabilities to third
parties, could require the Company to seek licenses from third parties and
could, if such licenses are not available, prevent the Company from
manufacturing, selling or using certain of its products, any 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 such
litigation will be favorable to the Company.

PRODUCT LIABILITY

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. The Company has insurance coverage
which management believes is adequate to protect against product liability
losses as could otherwise materially affect the Company's financial position.
However, there can be no assurance that product liability claims will not exceed
such insurance coverage limits or that such insurance will be available in the
future on commercially reasonable terms, if at all.


                                       15

EMPLOYEES

As of December 31, 1998, the Company had nearly 14,000 employees, including
approximately 8,800 in operations, 900 in administration, 1,400 in research and
development and 2,600 in selling, marketing, distribution and related
administrative support. Of these employees, approximately 4,000 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. Competition for qualified, skilled personnel is
intense in the medical device industry. There can be no assurance that the
Company will be able in the future to attract and retain such personnel.

The Company is in the process of implementing a rationalization plan established
after acquiring Schneider. The rationalization plan takes into consideration
duplicate capacity and opportunities for further leveraging of cost and
technology platforms. The Company's actions approved and committed to in the
fourth quarter of 1998 will result in the displacement in 1999 of approximately
2,000 current positions, over half of which are manufacturing positions. The
Company expects that approximately 1,000 positions will be added in 1999 as a
result of the transition plan.

SEASONALITY

The Company's business, taken as a whole, is not materially affected by seasonal
factors.

(including administration, research, manufacturing, distribution and sales and
marketing space) totaled approximately 5.2 million square feet, of which
approximately 85% was owned by the Company and the balance was leased. As of
December 31, 1998, the Company's principal research facilities were located in
Massachusetts, Indiana, Minnesota, New Jersey, Florida, California, Washington,
New York, Ireland and Switzerland, and its major distribution centers were
located in Massachusetts, The Netherlands, Japan and Singapore. As of December
31, 1998, the Company maintained 16 manufacturing facilities, 11 in the United
States, three in Ireland, one in Switzerland and one in Puerto Rico. Many of
these manufacturing facilities produce and manufacture products for more than
one of the Company's divisions.

RECENT PATENT PROCEEDINGS

 On March 2, 1999, Medtronic AVE Inc., formerly known as Arterial Vascular
Engineering Inc. (AVE), filed a cross-border suit in The Netherlands against the
Company and various subsidiaries of the Company including SCIMED, alleging that
the Company's MAXXUM(TM), MAXXUM(TM) ENERGY, MAXXUM(TM) 29 MM, NIR(R) Primo(TM),
VIVA!(TM), EXPRESS PLUS and EXPRESS PLUS II balloon dilation catheters infringe
one of AVE's European patents. In this action, AVE requested relief covering The
Netherlands, Germany, the United Kingdom, France and Spain. The Company has not
yet filed its answer, but intends to deny the allegations of the complaint.

On March 18, 1999, Cook, Inc. filed suit against the Company and SCIMED,
alleging that SCIMED's Radius(TM) coronary stent infringes a certain U.S. patent
owned by Cook. The suit was filed in the U.S. District Court for the Southern
District of Indiana seeking monetary damages and injunctive relief. The Company
has not yet been served.

The Company is involved in various lawsuits from time to time. In management's
opinion, the Company is not currently involved in any legal proceedings other
than those specifically identified above or in Note K to the Company's 1998
Consolidated Financial Statements which, individually or in the aggregate, could
have a material effect on the financial condition, operations or cash flows of
the Company.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

A Special Meeting of Stockholders of the Company was held on November 4, 1998 to
consider and vote upon a proposal to amend the Second Restated Certificate of
Incorporation, as amended, of the Company to increase the authorized number of
shares of Common Stock from 300,000,000 to 600,000,000 and the authorized number
of shares of Preferred Stock from 25,000,000 to 50,000,000. The amendment
allowed the Company's November 30, 1998 2-for-1 common stock split, effected in
the form of a 100% stock dividend, to occur. On September 15, 1998, the record
date for the Special Meeting, there were 196,367,418 shares of Common Stock
outstanding on a pre-stock split basis. The amendment was approved by a vote of
137,891,227 for, 9,618,374 against, 303,358 abstaining and 0 broker non-votes.

                                                                 to Amendment to
                                the Second Amended and Restated Credit Agreement


(h)      Notwithstanding anything to the contrary contained herein, any Lender
(a "GRANTING LENDER") may grant to a special purpose funding vehicle (an "SPC")
of such Granting Lender, identified as such in writing from time to time by the
Granting Lender to the Administrative Agent and the Borrower, the option to
provide to the Borrower all or any part of any Loan that such Granting Lender
would otherwise be obligated to make to the Borrower pursuant to Section 2.1 or
2.10, PROVIDED that (i) nothing herein shall constitute a commitment to make any
Loan by any SPC and (ii) if an SPC elects not to exercise such option or
otherwise fails to provide all or any part of such Loan, the Granting Lender
shall be obligated to make such Loan pursuant to the terms hereof. The making of
a Loan by an SPC hereunder shall satisfy the obligation of the Granting Lenders
to make Loans to the same extent, and as if, such Loan were made by the Granting
Lender. Each party hereto hereby agrees that no SPC shall be liable for any
payment under this Agreement for which a Lender would otherwise be liable, for
so long as, and to the extent, the related Granting Lender makes such payment.
In furtherance of the foregoing, each party hereto hereby agrees that, prior to
the date that is one year and one day after the payment in full of all
outstanding senior indebtedness of any SPC, it will not institute against or
join any other person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings or similar
proceedings under the laws of the United States or any State thereof. In
addition, notwithstanding anything to the contrary contained in this Section
12.6 any SPC may (i) with notice to, but without the prior written consent of,
the Borrower or the Administrative Agent and without paying any processing fee
therefor, assign all or a portion of its interests in any Loans to its Granting
Lender or to any financial institutions providing liquidity and/or credit
facilities to or for the account of such SPC to fund the Loans made by such SPC
or to support the securities (if any) issued by such SPC to fund such Loans and
(ii) disclose on a confidential basis any non-public information relating to its
Loans to any rating agency, commercial paper dealer or provider of a surety,
guarantee or credit or liquidity enhancement to such SPC. In no event shall the
Borrower be obligated to pay to an SPC that has made a Loan any greater amount
than the Borrower would have been obligated to pay under this Agreement if the
Granting Lender had made such Loan. Each Granting Lender shall indemnify and
hold harmless the Borrower and its directors, officers, employees and agents
from and against any and all losses, liabilities, claims, damages and expenses
arising from or attributable to the making of a Loan by an SPC of such Granting
Lender.

                                                            the Credit Agreement

(h)               Notwithstanding anything to the contrary contained herein, any
Lender (a "GRANTING LENDER") may grant to a special purpose funding vehicle (an
"SPC") of such Granting Lender, identified as such in writing from time to time
by the Granting Lender to the Administrative Agent and the Borrower, the option
to provide to the Borrower all or any part of any Loan that such Granting Lender
would otherwise be obligated to make to the Borrower pursuant to Section 2.1,
PROVIDED that (i) nothing herein shall constitute a commitment to make any Loan
by any SPC and (ii) if an SPC elects not to exercise such option or otherwise
fails to provide all or any part of such Loan, the Granting Lender shall be
obligated to make such Loan pursuant to the terms hereof. The making of a Loan
by an SPC hereunder shall satisfy the obligation of the Granting Lenders to make
Loans to the same extent, and as if, such Loan were made by the Granting Lender.
Each party hereto hereby agrees that no SPC shall be liable for any payment
under this Agreement for which a Lender would otherwise be liable, for so long
as, and to the extent, the related Granting Lender makes such payment. In
furtherance of the foregoing, each party hereto hereby agrees that, prior to the
date that is one year and one day after the payment in full of all outstanding
senior indebtedness of any SPC, it will not institute against or join any other
person in instituting against, such SPC any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings or similar proceedings under
the laws of the United States or any State thereof. In addition, notwithstanding
anything to the contrary contained in this Section 10.6 any SPC may (i) with
notice to, but without the prior written consent of, the Borrower or the
Administrative Agent and without paying any processing fee therefor, assign all
or a portion of its interests in any Loans to its Granting Lender or to any
financial institutions providing liquidity and/or credit facilities to or for
the account of such SPC to fund the Loans made by such SPC or to support the
securities (if any) issued by such SPC to fund such Loans and (ii) disclose on a
confidential basis any non-public information relating to its Loans to any
rating agency, commercial paper dealer or provider of a surety, guarantee or
credit or liquidity enhancement to such SPC. In no event shall the Borrower be
obligated to pay to an SPC that has made a Loan any greater amount than the
Borrower would have been obligated to pay under this Agreement if the Granting
Lender had made such Loan. Each Granting Lender shall indemnify and hold
harmless the Borrower and its directors, officers, employees and agents from and
against any and all losses, liabilities, claims, damages and expenses arising
from or attributable to the making of a Loan by an SPC of such Granting Lender.

                   AGREEMENT AND GENERAL RELEASE OF ALL CLAIMS


                  This Agreement and General Release of All Claims ("Agreement")
dated as of December 30. 1998 is entered into by and between James M. Corbett
("You") and Boston Scientific Corporation ("BSC"). This Agreement supersedes and
cancels for periods following the Termination Date (as hereinafter defined) any
and all prior employment agreements (including the employment agreement
concerning any change in control and dated October 19, 1992) or arrangements You
may have entered into with BSC or its affiliates.

                  In consideration of the mutual covenants, agreements, and
representations contained herein, the adequacy of which is hereby acknowledged,
the parties hereto expressly and intentionally bind themselves as follows:

         1.       TERMINATION OF EMPLOYMENT

                  You hereby acknowledge and agree that effective on or about
October 21, 1998 ("Transition Date") You relinquished day-to-day job
responsibilities as President, BSC International on behalf of BSC. You further
acknowledge and agree that your position as an employee of BSC will end on
December 31, 1998 ("Termination Date"). For the period between your Transition
Date and Termination Date, You agree to provide such assistance to BSC in
connection with your job duties as from time to time may be requested.

         2.       PAYMENTS BY BSC

                  (a) For the period between your Transition Date and
Termination Date, BSC will pay to You on each regular payroll cycle the
bi-weekly portion of your current BSC base annual salary of the sum of Three
Hundred Thirty-eight Thousand Dollars and no cents ($338,000.00), less
applicable payroll withholding for taxes and other applicable deductions.

                  (b) In addition, BSC will pay to You in a single payment on or
about January 15, 1999 the sum of Three Hundred Thirty-Eight Thousand Dollars
and no cents ($338,000.00). The parties acknowledge that this payment is in
consideration of the releases granted and representations made by You in
Sections 5 and 6 hereof and of the other obligations undertaken by You in this
Agreement. You expressly acknowledge that upon the occurrence of the Termination
Date, You will not be eligible for any payments or benefits in addition to those
described in this Agreement under any existing BSC Severance Pay Plan and/or
Layoff Notification Plan, change in control agreement, or any other such plan,
policy or agreement.

                  (c) BSC will pay You for all accrued but unused vacation time
through the Termination Date in accordance with applicable state law.

         3.       TERMINATION OF EMPLOYMENT BENEFITS

                  (a) You agree and acknowledge that your participation in BSC's
401(k) Plan, Stock Option Plan(s), and Global Employee Stock Option Plan, if
any, Accidental Death and Dismemberment (AD&D), Business Travel Accident, and
Short-Term and Long-Term Disability Plans will terminate as of your Termination
Date, as will your accrual of vacation time under the applicable BSC vacation
policy. You further agree and acknowledge that you will participate through the
Termination Date in all other benefits and benefit plans in which you are
enrolled to the same extent as do active employees and that your participation
in and entitlement to any and all other benefits and benefits plans in which You
are currently enrolled, but which are not otherwise specifically addressed in
this Agreement, terminates on the Termination Date or according to the same
terms and conditions as are available to terminating BSC employees generally,
whichever is applicable.

                  (b) Your participation in BSC's Medical/Dental/Vision Plans
(as well as the participation of any of your dependents who were covered by such
Plans one month prior to the Transition Date) shall continue after the
Termination Date on the same terms and conditions as such coverage is made
available from time to time to terminating BSC employees generally. You will be
responsible for making timely payments for the full costs (plus a 2%
administrative fee) of continued participation in BSC's Medical/Dental/Vision
Plans for an additional period of up to eighteen (or possibly more) months as
provided by the Consolidated Omnibus Budget and Reconciliation Act of 1985
("COBRA"), should You elect it. To enable BSC to comply with its obligation to
provide notification of your eligibility to continue Medical/Dental/Vision Plan
coverage, You agree to inform BSC of any change in address or marital status.
You also acknowledge that you understand that the terms of BSC's
Medical/Dental/Vision Plans offered to BSC employees generally may change from
time to time, and that your coverage and associated contribution costs will be
subject to any such change.

                  (c) Any unvested portions of previously awarded stock option
grants will continue to vest through the Termination Date and will become
exercisable under the terms and conditions contained in the applicable plan
documents.

                  (d) BSC will reimburse You in accordance with usual BSC policy
for all unreimbursed business travel and other out-of-pocket expenses incurred
by You through the Termination Date in the performance of your duties as an
employee of BSC. Such expenses must be submitted no later than the Termination
Date.

         4.       FUTURE EMPLOYMENT

                  You agree that You will not apply for employment or seek
re-employment at any time in the future with BSC or any of its subsidiaries,
affiliates, successors or assigns.

         5.       RELEASE BY YOU

                  Except as otherwise provided in this Section 5, You hereby
release and forever discharge BSC and its subsidiaries, affiliates, successors,
and assigns and the Directors, officers, shareholders, employees,
representatives and agents of each of the foregoing (collectively "Releasees")
of and from the following up to and as of the date of execution of this
Agreement:

                  (a) Any and all claims, demands, and liabilities whatsoever of
every name and nature (other than those arising directly out of this Agreement),
including (without limitation) those with respect to Your employment or the
terms and conditions or termination of his employment, benefits or compensation
which You have against Releasees, or ever had;

                  (b) As included in the above, without limitation, all claims
known or which reasonably could have been known for tortious injury, breach of
contract, and wrongful discharge (including without limitation, any claim for
constructive discharge), all claims for infliction of emotional distress, all
claims for slander, libel, or defamation of character, all claims for
retaliation, and all claims for attorneys' fees, as related to Your employment
by BSC, or the terms and conditions or termination of his employment, benefits,
or compensation; and

                  (c) You specifically releases and forever discharges Releasees
from any and all claims based upon any allegation of employment discrimination,
including (without limitation) discrimination on the basis of race, color, sex,
age (including any claim pursuant to the Federal Age Discrimination in
Employment Act), religion, disability or national origin.

                  BSC agrees that in the event that the Releasees initiate
litigation, arbitration, mediation or otherwise assert legal or equitable claims
against You, then notwithstanding the releases provided for in this Section 5
and the representations made in Section 6 hereof, You may assert as
counterclaims, crossclaims or set-offs against Releasees any and all claims You
may have against Releasees, including any claims that otherwise were released by
this Section 5 and further including any such claims that as of the Termination
Date would not have been barred by applicable statutes of limitation, provided
Your right to make such assertions shall not be triggered in the event BSC seeks
repayment of indemnification payments in accordance with Delaware General
Corporation Law or enforcement of Your obligations under this Agreement.

                  You acknowledge that You have been given the opportunity, if
You so desires, to consider this Agreement for twenty-one (21) days before
executing it. In the event that You execute the Agreement within less than
twenty-one (21) days of the date of its delivery to You, You acknowledge that
such decision was entirely voluntary and that You had the 


                                       3
<PAGE>   4

                                                                        
opportunity to consider this Agreement for the entire twenty-one (21) day
period. You agree that any modifications, material or otherwise, made to this
Agreement do not restart or affect in any manner the original twenty-one (21)
day consideration period. BSC acknowledges that for a period of seven (7) days
from the date of the execution of this Agreement, You shall retain the right to
revoke this Agreement by written notice to BSC, c/o Robert G. MacLean, Senior
Vice President, Human Resources, Boston Scientific Corporation, One Boston
Scientific Please, Natick, MA 01760, and that this Agreement shall not become
effective or enforceable until the expiration of such revocation period.
Therefore, no payments called for by BSC under Section 2(b), above, shall be
made until the expiration of such revocation period.

         6.       NO DAMAGES SOUGHT; FUTURE ACTIONS

                  (a) You represent and state that You have not and will not
seek any damages in connection with any complaints or charges filed against
Releasees with any local, state or federal agency or court, and You agrees that
if any complaint or charge is filed on Your behalf, You shall take all
reasonable steps necessary to refuse any compensation in connection with any
such claimed damages.

                  (b) In addition, to the extent permitted by applicable law,
You represent and warrant that You have not previously recommended or suggested,
and You will not recommend or suggest, to any federal, state or local
governmental agency or any potential claimants against or employees of the
Releasees, that they initiate any claim or lawsuit against the Releasees, and,
again to the extent permitted by applicable law, You will not voluntarily aid,
assist or cooperate with any claimants against or employees of the Releasees in
bringing such claims or lawsuits; provided, however, that nothing in this
Section 6 will be construed to prevent You from giving truthful testimony in
response to direct questions asked pursuant to a lawful subpoena or other legal
process during any legal proceeding involving the Releasees.

         7.       NO LIABILITY ADMITTED

                  You acknowledges that neither BSC's execution of this
Agreement nor BSC's performance of any of its terms shall constitute an
admission by BSC of any wrongdoing on Releasees' parts with respect to You in
connection with any matter, including (without limitation) the matters set forth
in Section 5, above.

         8.       NONDISCLOSURE OF CONFIDENTIAL INFORMATION

                  (a) You shall keep entirely secret and confidential, and shall
not disclose to any person or entity, in any fashion or for any purpose
whatsoever, any information that is (i) not available to the general public,
and/or (ii) not generally known outside BSC, regarding Releasees to which You
have had access or about which You heard during the course of Your employment by
BSC, including (without limitation) any information relating to BSC's business
or operations; BSC plans, strategies, prospects or objectives; BSC products,
technology, processes or 


                                       4

and customer lists; BSC manufacturing, distribution, sales, service, support and

operations; BSC operational strengths and weaknesses; and BSC personnel and

                  (b) You agree to return to BSC, on or before the Termination
Date, documents or media of whatever nature, including summaries containing any
of the data referred to in the immediately preceding paragraph whatsoever,
including all documents, data, material, details and copies thereof in any form.
You agree to return to BSC, on or before the Termination Date, all BSC property,
including (without limitation) all computer equipment, property passes, keys,
credit cards, business cards, identification badges, and all sample and
demonstration products.

         9.       NO DETRIMENTAL COMMUNICATIONS

                  You agree that You will not disclose or cause to be disclosed
any negative, adverse or derogatory comments or information about Releasees,
about any product or service provided by Releasees, or about Releasees'
prospects for the future. Furthermore, You hereby represent to BSC that You have
made no such communication to any public official, to any person associated with
the media, or to any other person or entity. You acknowledge that BSC relies
upon this representation in agreeing to enter into this Agreement.

                  BSC agrees that its executive officers and directors will
exercise reasonable business judgment and good faith not to disclose or cause to
be disclosed any negative, adverse or derogatory comments or information about
You or Your employee relationship with BSC or its affiliates. BSC further agrees
to respond to inquiries by your potential future employers and/or business
partners only after consultation or as may be agreed with You. BSC acknowledges
that You have relied upon this representation in agreeing to enter into this
Agreement.

                  Nothing in this Section 9 will be construed to prevent You or
BSC from giving truthful testimony in response to direct questions asked
pursuant to a lawful subpoena or other legal process during any legal proceeding
involving You or BSC.

         10.      FUTURE ASSISTANCE

                  BSC may seek Your assistance, cooperation or testimony in
connection with any investigation, litigation, patent application or
prosecution, or intellectual property or other proceeding arising out of matters
within Your knowledge and related to Your position as an employee of BSC, and in
any such instance, You shall provide such assistance, cooperation or testimony
and BSC shall pay Your reasonable costs and expenses in connection therewith.

                  During the period from the Termination Date through
twenty-four (24) months from the Termination Date, You shall not attempt to hire
away any employee of BSC or any of its affiliates (collectively the "Company"),
assist in the hiring away of any of the Company's employees by another person,
or encourage any Company employee to terminate his or her employment with the
Company, whether directly or indirectly, unless the President of BSC or his
designee shall have given prior written approval.

         12.      POST-SEPARATION RESTRICTION

                  In consideration of BSC's obligations hereunder, You agree
that, during the period beginning as of the Termination Date and ending
twenty-four months thereafter, he shall not, directly or indirectly, without the
written consent of an Executive Officer of BSC, engage in any activity or
provide any service for a company, business unit, entity or person who develops,
manufactures, markets or sells less invasive medical devices that are
competitive with products offered by BSC or known to You to be proposed to be
offered by BSC indicated for use in the fields of cardiology, radiology,
urology, gastroenterology, neurology or vascular surgery (the "Fields"). To the
extent and from the date You demonstrate that BSC has failed to materially
perform its obligations under Section 9 hereof, Your obligations under this
Section 12 shall lapse.

         13.      CONFIDENTIALITY

                  You agree to keep confidential the existence of this
Agreement, as well as all of its terms and conditions, and not to disclose to
any person or entity the existence, terms or conditions of this Agreement except
to his attorney, financial advisors and members of his immediate family provided
they agree to keep confidential the existence, terms and conditions of this
Agreement. In the event that You believe you are compelled by law to divulge the
existence, terms or conditions of this Agreement, he will notify BSC (by
notifying BSC's Legal Department) of the basis for the belief sufficiently in
advance of actually divulging the information to enable BSC to seek appropriate
protective orders. You hereby confirm that as of the date of signing this
Agreement, You have not disclosed the existence, terms or conditions of this
Agreement, except as permitted by this Section 13. In the event of a breach of
this Agreement, You shall repay to BSC all of the amounts paid under Section
2(b), above, and will be liable, moreover, for any damages which a court may
determine and will be subject to injunctive relief damages, and any other relief
which a court may award.

         14.      GOVERNING LAW; SEVERABILITY

                  This Agreement is entered into and shall be construed under
the laws of the Commonwealth of Massachusetts, without regard to its conflict of
law rules, and suits to enforce rights and obligations hereunder shall be
brought exclusively in a court of competent jurisdiction 


                                       6
<PAGE>   7

in the Commonwealth of Massachusetts. In the event any provision of this
Agreement is determined to be illegal or unenforceable by a duly authorized
court of competent jurisdiction, then the remainder of this Agreement shall not
be affected thereby, it being the intention of the parties that each provision
of this Agreement shall be valid and enforceable to the fullest extent permitted
by law. However, if any portion of the General Release language in Section 5,
above, is ruled to be unenforceable for any reason, You shall return the
consideration paid under Section 2(b), above, to BSC upon demand by BSC, which
demand shall be made if You were to file any claim against BSC in violation of
this Agreement, especially Section 6.

         15.      INDEMNIFICATION

                  In the event You were, are or become a party to or witness or
other participant in, or is threatened to be made a party to or witness or other
participant in, a claim by reasons of (or arising in part out of) an
Indemnifiable Event (as defined below), BSC shall indemnify You to the fullest
extent permitted by law and upon receipt of an appropriate undertaking in
accordance with Delaware General Corporation Law against any and all reasonable
expenses, judgments, fines, penalties and amounts paid in settlement approved in
advance by BSC (including all interest, assessments and other charges paid or
payable in connection with or in respect of such expenses, judgments, fines,
penalties or amounts paid in settlement) of such claim. For purposes of this
Agreement, "Indemnifiable Event" means any event or occurrence that takes place
either prior to or after the execution of this Agreement related to the fact
that You are or were is or was an officer, director, employee, agent or
fiduciary of BSC, or is or was serving at the request of BSC as a director,
officer, employee, trustee, agent or fiduciary of another corporation,
partnership, joint venture, employee benefit plan, trust or other enterprise, or
by reason of anything done or not done by Indemnitee in any such capacity. It
shall be a defense to any action brought by You against BSC to enforce this
indemnification obligation that You has not met the standards of conduct that
make it permissible under the Delaware General Corporation Law for BSC to
indemnify You for the amount claimed.

         16.      WAIVERS; AMENDMENTS

                  The failure of either party to require the performance of any
term or obligation of this Agreement, or the waiver by either party of any
breach of this Agreement, shall not prevent any subsequent enforcement of such
term or obligation and shall not be deemed a waiver of any subsequent breach. No
modification or waiver of any provision of this Agreement shall be effective
unless in writing and signed by both parties.

         17.      NO OTHER INDUCEMENTS

                  This Agreement sets forth the entire understanding of the
parties in connection with the subject matter hereof. Any and all prior
negotiations are merged in this Agreement. Neither of the parties has made any
settlement, representation or warranty in connection herewith 


                                       7
<PAGE>   8

(except those expressly set forth in this Agreement) which has been relied upon
by the other party, or which acted as an inducement for the other party to enter
into this Agreement.

         18.      PERSONS BOUND BY THE AGREEMENT

                  This Agreement shall be binding upon and inure to the benefit
of You and BSC and their respective successors.

         19.      ASSIGNMENT OF INTERESTS

                  You warrant that You have not assigned or transferred or
purported to assign or transfer any claim against Releasees. In addition, You
shall for a period of one (1) year after the Termination Date, promptly report
and disclose to BSC all ideas, inventions and concepts developed or conceived in
the Fields ("Inventions"), which You agree shall be presumed to have been
developed or conceived during the term of Your employment with BSC or its
affiliates. Inventions shall be the property of BSC and are hereby assigned to
BSC without any additional payments to You by BSC. It is understood that BSC
shall have the right but not the obligation to initiate, prosecute, maintain and
defend, at its expense, any and all patents fileable with respect to Inventions.
You shall provide reasonable assistance to BSC with respect to any such patents
and patent applications, and shall execute all appropriate documents and
assignments with respect to any such patents and patent applications.

         20.      FEES

                  In the event that any action or proceeding is initiated to
enforce or interpret the provisions of this Agreement, or to recover for a
violation of the Agreement, each party in any such action or proceeding shall be
bear its own costs and expenses (including attorneys' fees).

         21.      REPRESENTATION

                   AGREEMENT AND GENERAL RELEASE OF ALL CLAIMS


                  This Agreement and General Release of All Claims ("Agreement")
is entered into by and between Charles M. Mabrey ("You" or "Employee") and
Boston Scientific Corporation ("BSC") as of the latest date of execution by the
parties to this Agreement. This Agreement supersedes and cancels any prior
employment agreements or arrangements You may have entered into with BSC except
for the Employment Agreement ("Employment Agreement") signed by You on May 19,
1987, and attached hereto as Attachment 1. Employee's obligations under the
Employment Agreement shall be in addition or complementary to, and shall not be
superseded, by this Agreement.

                  In consideration of the mutual covenants, agreements, and
representations contained herein, the adequacy of which is hereby acknowledged,
the parties hereto expressly and intentionally bind themselves as follows:

         1.       TRANSITION AND ULTIMATE TERMINATION OF EMPLOYMENT

                  You hereby acknowledge and agree that effective January 1,
1999 ("Transition Date") your position as a full-time Senior Vice President,
Operations, of BSC will transition to that of a part-time employee working one
hundred (100) hours per quarter. You further acknowledge and agree that your
position as Senior Vice President, Operations, of BSC and as an employee of BSC
will end entirely on December 31, 2000, subject to possible earlier termination
as set forth in Paragraph 5(d), below ("Termination Date"). For the period
between the Transition Date and Termination Date, You will continue to perform
the job responsibilities referenced in Paragraph 5(a), below.

         2.       PAYMENTS BY BSC

                  (a) For the first twelve-(12) month period (the "First
Twelve-(12) Month Period") immediately following the Transition Date, BSC will
pay to You on each regular payroll cycle the bi-weekly portion of your current
BSC base annual salary of the sum of Two Hundred Seventy Thousand Four Dollars
and Eighty cents ($270,004.80) (i.e., $10,384.80 per bi-weekly payroll cycle),
less applicable payroll withholding for taxes and other applicable deductions.
These payments will be made as compensation for the job responsibilities to be
undertaken by You as referenced in Paragraph 5(a), below.


                                       1
<PAGE>   2

                  (b) For the second twelve-(12) month period (the "Second
Twelve-(12) Month Period") following the Transition Date, BSC will pay to You on
each regular payroll cycle the bi-weekly portion of the sum of Five Thousand
Dollars and no cents ($5,000.00) per quarter (i.e., $769.23 per bi-weekly
payroll cycle), less applicable payroll withholding for taxes and other
applicable deductions. These payments will be made in recognition of and as
compensation for the reduced job responsibilities to be undertaken by You during
the Second Twelve-(12) Month Period, such reduced responsibility to consist
primarily of your provision of transition assistance to your successor(s) on an
as-needed basis. You expressly acknowledge that upon the occurrence of the
Termination Date, You will not be eligible for any payments or benefits in
addition to those described in this Agreement under any existing BSC Severance
Pay Plan and/or Layoff Notification Plan.

                  (c) To help defray the incremental costs you may incur in
securing health insurance coverage for You and your spouse (over and above your
normal contribution) once your participation in the BSC medical and dental
programs ceases, BSC will pay you within a reasonable period of time after June
30, 2000 a one-time bonus in the gross amount of Seventy Thousand Dollars and no
cents ($70,000.00), which includes a "grossed up" amount to account for tax
obligations you will incur as a result of this payment.

                  (d) BSC will pay You for all accrued but unused vacation time
through the Termination Date in accordance with applicable Massachusetts law.

         3.       STATUS OF EMPLOYMENT BENEFITS 

                  (a) The Split Dollar Life Insurance Policy currently in place
         on your behalf will remain in place, and all of the terms and
         conditions of that Policy will continue to apply.

                  (b) As of January 1, 1999, you will have the opportunity to
convert the group dependent life insurance coverage you have elected to a
non-group life insurance plan upon meeting applicable eligibility requirements.

                  (c) You agree and acknowledge that your participation in BSC's
Global Employee Stock Option Plan, if any, Accidental Death and Dismemberment
(AD&D), Business Travel Accident, and Short-Term and Long-Term Disability Plans
will terminate as of your Transition Date; that your accrual of vacation time
under the applicable BSC vacation policy will continue through the Termination
Date and will be based on your scheduled number of work hours; that you will not
be eligible to receive holiday pay; and that your participation in BSC's 401(k)
Plan will continue, based on your scheduled number of work hours, through the
Termination Date. You further agree and acknowledge that you will participate
through the Termination Date in all other benefits and benefit plans in which
you are currently enrolled in accordance with the eligibility accorded part-time
employees who work the number of hours for 


                                       2
<PAGE>   3

which you have been scheduled and that your participation in and entitlement to
any and all other benefits and benefit plans in which You are currently
enrolled, but which are not otherwise specifically addressed in this Agreement,
terminates according to the same terms and conditions as are available to BSC
employees generally.

                  (d) For the period January 1, 1999 through June 30, 2000, your
participation in BSC's Medical/Dental Plans shall continue, on the same terms
and conditions as are made available to BSC employees generally, as provided by
the Consolidated Omnibus Budget and Reconciliation Act of 1985 ("COBRA"). You
may cancel such coverage at any time prior to June 30, 2000, should you desire
to do so. BSC will pay the employer's portion of the insurance premium for any
such medical/dental coverage elected through June 30, 2000. You acknowledge that
the terms of the BSC Medical/Dental Plans offered to BSC employees generally may
change from time to time, and that your coverage will be subject to any such
change.

                  (e) Any unvested portions of previously awarded stock option
grants will continue to vest through the Termination Date and will become
exercisable under the terms and conditions contained in the applicable plan
documents.

                  (f) BSC will arrange to transfer to you as a gift, effective
January 1, 1999, ownership of the leased vehicle currently in your possession
through BSC's leasing program. Any tax obligations associated with the value of
this transfer will be your personal responsibility.

         4.       EXPENSE REIMBURSEMENT

                  BSC will reimburse you in accordance with usual BSC policy for
all unreimbursed business travel and other out-of-pocket expenses incurred by
you through the Termination Date in the performance of your duties as an
employee of BSC. Such expenses must be submitted no later than the Termination
date.

         5.       PART-TIME EMPLOYMENT FOR THE PERIOD JANUARY 1, 1999 THROUGH 
DECEMBER 30, 2000.

                  (a) As described in Paragraph 1, above, Employee shall be
employed by BSC as a part-time employee through the Termination Date. Attached
to this Agreement as Attachment 2 is a description of the responsibilities to be
performed by Employee through the Termination Date.

                  (b) At all times through the Termination Date, Employee shall
observe all policies and guidelines established by BSC with respect to its
employees, including but not limited to the Company's Code of Conduct and
Employee Information Guide.

<PAGE>   4

                  (c) Prior to the Termination Date, Employee shall not work for
or otherwise provide services for any other business, entity or person on a
full-time basis or in any other way which would interfere with his ability to
fully perform his part-time employment responsibilities in accordance with this
Section 5.
                  (d) Notwithstanding anything to the contrary in this
Agreement, at any time prior to the Termination Date, BSC may change Employee's
Termination Date to a date earlier than December 31, 2000 immediately upon
notice to Employee if it determines that any of the following has occurred: (i)
Employee has not signed and returned this Agreement prior to the end of the
21-day period referenced in Section 6(b), or has revoked or rescinded this
Agreement pursuant to Section 7 of this Agreement; (ii) Employee has not
cooperated in good faith to fulfill his obligations and agreements under
Sections 5(a), (b) and (c), above, through and including the Termination Date;
or (iii) Employee has materially breached any of his other obligations or
agreements under this Agreement or the Employment Agreement.

                  (e) If Employee's employment with BSC ends prior to December
31, 2000 as set forth in Section 5(d), above, in addition to any other remedies
available to BSC: (i) BSC may cease making any payments under Sections 2(a), (b)
and (c), above, provided, however, that such cessation of payments or other
consideration shall neither nullify nor otherwise affect the enforceability of,
or any of Employee's obligations under, this Agreement; and (ii) any reference
in this Agreement to "Termination Date" shall refer to such earlier Termination
Date.

         6.       RELEASE BY EMPLOYEE

                  (a) Employee hereby releases and forever discharges BSC and
its subsidiaries, affiliates, successors, and assigns and the Directors,
officers, shareholders, employees, representatives and agents of each of the
foregoing (collectively "Releasees") of and from the following as of the date of
execution of this Agreement:

                      (i) Any and all claims, demands, and liabilities
                      whatsoever of every name and nature (other than those
                      arising directly out of this Agreement), including
                      (without limitation) those with respect to Employee's
                      employment or the terms and conditions or termination of
                      his employment, benefits or compensation which Employee
                      has against Releasees, or ever had;

                      (ii) As included in the above, without limitation, all
                      claims known or which reasonably could have been known for
                      tortious injury, breach of contract, and wrongful
                      discharge (including without limitation, any claim for
                      constructive discharge), all claims for infliction of
                      emotional distress, all claims for slander, libel, or
                      defamation of character, all claims for retaliation and

<PAGE>   5

                      employment by Releasees, or the terms and conditions or
                      termination of his employment, benefits, or compensation;
                      and

                      (iii) Employee specifically releases and forever
                      discharges Releasees from any and all claims based upon
                      any allegation of employment discrimination, including
                      (without limitation) discrimination on the basis of race,
                      color, sex, age (including without limitation any claim
                      pursuant to the Federal Age Discrimination in Employment
                      Act), religion, disability or national origin.

                  (b) Employee acknowledges that he has been given the
opportunity, if he so desires, to consider this Agreement for 21 days before
executing it. If Employee executes this Agreement within less than 21 days of
the date of its delivery to him, he acknowledges that such decision was entirely
voluntary and that he had the opportunity to consider this Agreement for the
entire 21-day period. Employee agrees that any modifications, material or
otherwise, made to this Agreement do not restart or affect in any manner the
original twenty-one (21) day consideration period.

                  7.       RESCISSION

                  BSC acknowledges that for a period of seven (7) days from the
date of the execution of this Agreement, Employee shall retain the right to
revoke this Agreement by written notice to Boston Scientific Corporation, c/o
Robert G. MacLean, Senior Vice President, Human Resources, One Boston Scientific
Place, Natick, MA 01760, and that this Agreement shall not become effective or
enforceable until the expiration of such revocation period. Therefore, no BSC
obligations will be met and payments called for by BSC shall not be made under
Sections 2(a), (b) and (c), above, until the expiration of such revocation
period.

                  8.       NO DAMAGES SOUGHT; FUTURE ACTIONS

                  (a) Employee represents and states that he has not and will
not seek any damages in connection with any complaints or charges filed against
Releasees with any local, state or federal agency or court, and Employee agrees
that if any complaint or charge is filed on his behalf, he shall take all
reasonable steps necessary to refuse any compensation in connection with such
claimed damages.

                  (b) In addition, to the extent permitted by applicable law,
Employee represents and warrants that he has not previously recommended or
suggested, and he will not recommend or suggest, to any federal, state or local
governmental agency or any potential claimants against or employees of the
Releasees, that they initiate any claim or lawsuit against the Releasees, and,
again to the extent permitted by applicable law, Employee will not voluntarily
aid, assist or cooperate with any claimants against or employees of the
Releasees in bringing such claims or lawsuits; provided, however, that nothing
in this Paragraph 8 will be 


                                       5
<PAGE>   6

construed to prevent Employee from giving truthful testimony in response to
direct questions asked pursuant to a lawful subpoena or other legal process
during any future legal proceeding involving the Releasees.

         9.       NO LIABILITY ADMITTED

                  Employee acknowledges that neither BSC's execution of this
Agreement nor BSC's performance of any of its terms shall constitute an
admission by BSC of any wrongdoing on Releasees' parts with respect to Employee
in connection with any matter, including (without limitation) the matters set
forth in Paragraph 6, above.

         10.      NONDISCLOSURE OF CONFIDENTIAL INFORMATION

                  (a) Employee shall keep entirely secret and confidential, and
shall not disclose to any person or entity, in any fashion or for any purpose
whatsoever, any information that is: (i) not available to the general public;
and/or (ii) not generally known outside BSC, regarding Releasees to which he has
had access during the course of his employment by BSC, including (without
limitation) any information relating to BSC's business or operations; its plans,
strategies, prospects or objectives; its products, technology, processes or
specifications; its research and development operations or plans; its customers
and customer lists; its manufacturing, distribution, procurement, sales,
service, support and marketing practices and operations; its financial
conditions and results of its operations; its operational strengths and
weaknesses; and its personnel and compensation policies, procedures and
transactions.

                  (b) Employee agrees to return to BSC, on or before the
Termination Date, documents or media of whatever nature, including summaries
containing any of the notes or data referred to in the immediately preceding
paragraph whatsoever, including all documents, data, material, details and
copies thereof in any form. Employee agrees to return to BSC, on or before the
Termination Date, all BSC property, including (without limitation) all computer
equipment, property passes, keys, credit cards, business cards, identification
badges, and all sample and demonstration products.

         11.      NO DETRIMENTAL COMMUNICATIONS

                  Employee agrees that he will not disclose or cause to be
disclosed any negative, adverse or derogatory comments or information about
Releasees, about any product or service provided by Releasees, or about
Releasees' prospects for the future. Furthermore, Employee hereby represents to
BSC that he has made no such communication to any public official, to any person
associated with the media, or to any other person or entity. Employee
acknowledges that BSC relies upon this representation in agreeing to enter into
this Agreement.

         12.      FUTURE ASSISTANCE

                  BSC may seek the assistance, cooperation or testimony of
Employee in connection with any investigation, litigation, patent application or
prosecution, or intellectual property or other proceeding arising out of matters
within the knowledge of Employee and related to his position as an employee of
BSC, and in any such instance, Employee shall provide such assistance,
cooperation or testimony and BSC shall pay Employee's reasonable costs and
expenses in connection therewith.

         13.      HIRING OF BSC EMPLOYEES

                  During the period beginning as of the date Employee signs this
Agreement and for twenty-four (24) months thereafter, Employee shall not,
directly or indirectly, attempt to hire away any individual who was an employee
of BSC or any of the Releasees within the twelve (12)-month period immediately
preceding the Transition Date, assist in the hiring away of any such employee by
himself or any other person or entity, or encourage any such employee to
terminate his or her employment with BSC, whether directly or indirectly, unless
the President of BSC or his designee shall have given prior written approval.

         14.      POST-SEPARATION RESTRICTION

                  During the period beginning as of the date Employee signs this
Agreement, and for twenty-four (24) months thereafter, Employee agrees that he

Officer of BSC, engage in any activity in the area of medical device

Employee performed or with which Employee was familiar as an employee of BSC.

         15.      CONFIDENTIALITY

                  Employee agrees to keep confidential the existence of this
Agreement, as well as all of its terms and conditions, and not to disclose to
any person or entity the existence, terms or conditions of this Agreement except
to his attorney, financial advisors and members of his immediate family provided

         16.      GOVERNING LAW, SEVERABILITY

                  This Agreement is entered into and shall be construed under
the laws of the Commonwealth of Massachusetts without regard to its conflicts of
law rules. In the event any provision of this Agreement is determined to be
illegal or unenforceable by a duly authorized court of competent jurisdiction,
then the remainder of this Agreement shall not be affected thereby, it being the
intention of the parties that each provision of this Agreement shall be valid
and enforceable to the fullest extent permitted by law. However, if any portion
of the general release language in Paragraph 6, above, were ruled to be
unenforceable for any reason, Employee shall return the consideration provided
under Sections 2(a), (b) and (c), above, to BSC upon demand by BSC, which demand
shall be made if Employee were to file any claim against BSC in violation of
this Agreement, especially Paragraph 8.

         17.      WAIVERS, AMENDMENTS

                  The failure of either party to require the performance of any
term or obligation of this Agreement, or the waiver by either party of any
breach of this Agreement, shall not prevent any subsequent enforcement of such
term or obligation and shall not be deemed a waiver of any subsequent breach. No
modification, alteration, or change or waiver of any provision of this Agreement
shall be effective unless in writing and signed by both parties wherein specific
reference is made to this Agreement.

         18.      NO OTHER INDUCEMENTS

                  This Agreement sets forth the entire understanding of the
parties in connection with the subject matter hereof. Any and all prior
negotiations are merged in this Agreement. Neither of the parties has made any
settlement, representation or warranty in connection herewith (except those
expressly set forth in this Agreement) which has been relied upon by the other
party, or which acted as an inducement for the other party to enter into this
Agreement.

         19.      PERSONS BOUND BY THE AGREEMENT

                  This Agreement shall be binding upon and inure to the benefit
of Employee and BSC and their respective successors.

         20.      ASSIGNMENT OF INTERESTS

                  Employee warrants that he has not assigned or transferred or
purported to assign or transfer any claim against Releasees.

         21.      PREVAILING PARTY ENTITLED TO FEES

                  In the event that any action or proceeding is initiated to
enforce or interpret the provisions of this Agreement, or to recover for a
violation of the Agreement, the prevailing party in any such action or
proceeding shall be entitled to its costs (including reasonable attorneys'
fees).

         22.      REPRESENTATION

                  Employee represents that, prior to executing this Agreement,
he had the opportunity to review the provisions of this Agreement with counsel
of his choice.

                                 The parties have read the foregoing Agreement 
and know its contents, and know that its terms are contractual and legally
binding. The parties further agree that they enter this Agreement voluntarily
and that they have not been pressured or coerced in any way into signing this
Agreement.


IN WITNESS WHEREOF, the parties hereby agree.

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

In consideration of my employment by MEDI-TECH, Incorporated ("the Company"), I
agree to communicate to the Company all inventions, discoveries or improvements
(whether or not patentable) which I may make during the term of my employment.

If requested to do so by the Company, I agree to do whatever is necessary to
take out patents in any country and to assign all patents and applications
relating to them to the Company, before or after leaving its employment. It is
understood that the cost of making such assignments and procuring patents shall
be paid by the Company. I further agree that rights to all royalties resulting
from such patents will be the property of the Company.

If requested, but not otherwise, I agree to take out copyrights on work
resulting from specific Company assignments and to assign such copyrights to the
Company. I further agree that rights to all royalties resulting from such
copyrights will be the property of the Company. It is understood, however, that
copyrights resulting from professional activities of a general nature not
resulting from a specific Company assignment are my own property.

I recognize that I will have knowledge of business confidences of the Company,
including written material such as memoranda, sales records, product development
information, customer information, financial information, and laboratory
reports. I agree to hold confidential both during and after my employment all
such matters, over and above the ordinary skill of my profession, the disclosure
of which might prejudicially affect the Company or its clients. Upon termination
of employment I will not take written or printed material with me whether in the
form of printed reports, case memoranda, laboratory notebooks or any file
material whatsoever without the written permission of the Company.

I further agree that for a period of two years after the termination of my
employment with the Company, I will not, without the written consent of the
Company, work for or assist any business organization which competes with the
Company with respect to its products being sold or in development.


                                       10

As a condition of employment, I certify:

that to the best of knowledge, I have no commitments to any present or former
employer, or to any other parties, which could create a conflict of interest on
behalf of the Company its clients, and that I am free to disclose and make use
of non-confidential information except as noted below (if none, please state
so.)

CHAIRMAN'S LETTER

1998 was a year of growth on many fronts. We are stronger in several key areas.
We are clear about our future path, and we have the confidence and capability to
follow it successfully.

The year just completed was also a year of reckoning. While we took significant
steps forward in building the Strategic Mass we need to achieve our vision, we
also stumbled a few times. The recall of the NIR ON(TM) Ranger(TM) with SOX(TM)
stent system focuses attention on the need for relentless quality assurance. We
are cooperating fully with the Department of Justice investigation begun in the
wake of that recall, and believe the government will agree that the Company
acted appropriately. The discovery of business irregularities in our Japanese
operation makes us realize that, as we grow, we must develop better safeguards
to prevent such occurrences. And we must do a better job of communicating and
instilling our corporate values, including personal integrity and
accountability, throughout the global organization. Lastly, our failure to meet
earnings expectations highlights the overall problem that confronts us and about
which we have talked much: execution. We need to improve processes,
competencies, and leverage in order to come together as a single, unified
company and strengthen our overall business performance.

These are issues that often accompany rapid growth. We do not view them lightly;
we are learning from our experiences and incorporating those lessons into our
plans for the future. However, as we reflect upon our experiences in 1998, we
should not allow a few unfortunate events to overshadow the substantial
successes and great progress that occurred during the year-marked by the
favorable trends that emerged in the fourth quarter and are continuing into this
year.

ACQUISITIONS AND NEW PRODUCTS DRIVE GROWTH

Among our most significant achievements are two acquisitions made last year
which support our strategy of strengthening leadership in chosen fields through
increased sales volume, market presence and technological superiority.
Certainly, the most significant event was the acquisition of Schneider
Worldwide, a leader in catheter-based and stent technologies used in less
invasive treatment of cardiovascular, peripheral vascular and nonvascular
disease. Early in the year, the timing of the decision by Pfizer Inc. to divest
its worldwide medical device operations created an unexpected opportunity to
accelerate our Strategic Mass strategy. Combining our businesses was a natural
fit for two pioneering companies in the field of less invasive medicine, both
with strong traditions of innovation, complementary research efforts and a
genuine commitment to customer service.

Further, Schneider brought a rich pipeline of new development projects as well
as an attractive patent portfolio which at last permits Boston Scientific to
make available to physicians, in the United States, the Schneider-pioneered
Monorail(TM) catheter systems which we had developed into a leading franchise
outside the United States over the past 10-plus years. Access to this technology
not only enables Boston Scientific to introduce powerful new PTCA balloon
catheter and catheter-based stent delivery systems into the United States, but
also enables us to standardize product offerings in this market segment
worldwide.

Our second strategic acquisition, CardioGene Therapeutics, Inc., a development
stage company exploring the role and use of gene therapy to treat cardiovascular
and other diseases, represented an investment in the future by bringing Boston
Scientific the technologies and know-how we believe will enable us to remain on
the therapeutic frontier of a disease state where we already have developed a
well-established presence.

These companies bring technological expertise and strength, and deepen our
commitment in high-growth areas of interventional medicine. And, as important,
Schneider brings skilled and dedicated employees, many of whom have assumed key
leadership positions throughout the corporation. The recognized scientific and
commercial leadership positions Schneider possesses demonstrates the commitment
of its employees to excellence and less invasive medicine. We welcome them to
the Boston Scientific family.

We also grew internally, with continuing special emphasis on the emerging
markets in Asia Pacific, Latin America, Canada and Middle East/Africa. We are
well aware of the opportunities that lie in many of these countries where less



<PAGE>   5


invasive medicine is still in its infancy, and we are continuing, through market
development programs, to build our presence and leadership in these important
markets outside of the United States, Western Europe and Japan. Our goal is to
understand the unique needs of all of our different markets and to develop
long-term, direct relationships and partnerships with physicians around the
globe.

Media attention on the recall of our NIR ON(TM) Ranger(TM) with SOX(TM) stent
system has tended to eclipse the fact that the U.S. launches of the NIR ON(TM)
Ranger(TM) without SOX(TM) stent system and our Radius(TM) self-expanding stent
have been received with great enthusiasm. We hope to be able to relaunch the
SOX(TM) system in the United States once the balloon leakage problem has been
rectified and FDA approval has been received. Our efforts in the highly
competitive U.S. coronary stent market were also fortified by the introduction
of the Magic WALLSTENT(R) stent system toward the end of the year. Used
successfully in Europe since its 1997 introduction, the Magic WALLSTENT stent
system comes to us through the Schneider acquisition and gives us a second
self-expanding coronary stent platform, further broadening our offerings for the
treatment of both peripheral vascular and nonvascular disease. As a result of a
conscious strategy, Boston Scientific now offers five distinct stent technology
platforms which are selectively applied to the management of multiple
disease-specific states throughout the human anatomy.

RESHAPING OUR COMPANY FOR FUTURE SUCCESS

To say that we have grown dramatically in the past few years is an
understatement. Boston Scientific has become a much larger and interdependent
organization with greater geographic reach and broader, deeper product lines
continuously strengthened by an impressive and growing technology portfolio. The
process of assimilating this growth and developing and integrating new processes
and systems is a critical--and daunting--task. Although that process was well
underway when the opportunity to acquire Schneider Worldwide presented itself,
that acquisition enabled us to refine and further improve the rationalization
strategy for our worldwide organization and operations. Our goal has always been
to eliminate duplication and incompatibility, and encourage cooperation and the
achievement of cross-divisional synergies. This is happening. We have identified
and implemented improved ways of working-and working together-that will enable
our vastly larger and more complex company to sustain superior growth and return
to our high standards of overall business excellence and profitability.

Several 1998 efforts mark the beginning of this endeavor. We are rightsizing,
streamlining and integrating our European organization and facilities and now
believe we have a viable leadership blueprint for the future. We are
consolidating the worldwide Schneider Team into our global business model and
are already acting as one company. We have restructured and consolidated several
of our core business units to form a new U.S. Vascular division comprising
Medi-tech, Meadox, and the vascular group within Schneider. This enables us to
combine and leverage technologies more effectively, achieve more comprehensive
market coverage and operate from a disease management state, rather than a
medical specialty perspective. This vascular business unit model was already in
practice outside the United States and adopting this strategy in our domestic
markets gives us the added benefit of planning and executing our business on a
global basis.

All these efforts when combined focus on rationalizing our size and structure to
improve performance and efficiency worldwide. They are, however, only part of
the picture. Other essential work focuses on revamping our systems and processes
to provide the flexibility, coordination and leverage a multi-billion dollar
company needs for success. For example, in 1998 we began to reap the benefits of
our new global information system. While the efficiency


                                                                    [PHOTOGRAPH]
<PAGE>   6


improvements and cost savings we anticipate will not be fully felt in 1999, this
powerful enterprise-wide system, a work-in-progress since 1997, has enabled us
to achieve transparency of timely data worldwide on a need-to-know basis to
support our objectives of business excellence.

Another outgrowth of our recognition of the need for improvement has been the
formation in mid-1998 of four global task forces focused on mission-critical
areas of the company: supply chain optimization, innovation, quality and
organizational development. Each is charged with evaluating the current
organization and processes, identifying best practices, then formulating and
implementing revised structures and systems appropriate for a world class
operation. Each is also charged with promoting a greater sense of who we now
are, what we stand for and what we can accomplish together. By more efficiently
sharing our competencies, experience and commitments, we can leverage our many
separate strengths for the benefit of the divisions and the corporation as a
whole. The specific focus, scope and examples of the task force assignments are
discussed in the editorial section that follows this letter. Needless to say, I
consider these task forces among the most crucial undertakings of 1998. Their
work, continuing into and beyond 1999, is essential to our future success. It
will improve planning and execution, dramatically reduce working capital
requirements and improve gross margins for which performance metrics have now
become a daily way of life.

SUCCEEDING IN A CHANGING INDUSTRY

Although we still have work to do, we should take pride in our accomplishments.
Boston Scientific has an unparalleled portfolio of less invasive technologies
and products for treatment of specific disease states. Our business units are
today the clear market leaders worldwide in the markets within which they
compete. Despite the setbacks we experienced, sales and earnings momentum is
excellent, and the trends I spoke of earlier are a clear signal of what can be
achieved in 1999.

We have made some changes in the responsibilities of our management team to
ensure that the positive momentum continues to build. Philip Le Goff has taken
on the expanded responsibility of directing both our vascular and nonvascular
operations. Paul LaViolette's assignments within the company highlight the
growth we have undergone. He joined us in 1994 as President of Boston Scientific
International, moved on to other responsibilities and now returns to that
position, taking charge of an organization that is today larger and more complex
than Boston Scientific itself when Paul joined the company. Paul succeeds Jim
Corbett who has resigned to pursue interests elsewhere. Jim was the architect
and force behind the creation of our current International organization for
which we give him our thanks. Finally, Mike Mabrey, Senior Vice President,
Operations, has elected to retire after twelve years of service. During this
period, we acquired and merged with 10 major companies where Mike was
specifically responsible for developing and overseeing the manufacturing
operations integration strategy and execution. The Team thanks Mike for his
solid record of achievement and exemplary behavior over the years as a senior
Boston Scientific executive. We wish both Mike and Jim well as they look forward
to futures beyond Boston Scientific.

Most significantly, on March 18, 1999, I announced the appointment of James R.
Tobin as President and Chief Executive Officer of Boston Scientific. This is a
landmark event in the history of our Company. Eighteen months ago, we began a
process to put in place an effective succession plan to ensure continued
leadership of our great Company. In May of 1998, we launched a formal search for
a strong, seasoned leader. I am pleased that we discovered Jim Tobin and that he
agreed to join us and will immediately assume leadership of our organization. I
am confident that he is the right person to lead our Team. Jim is an
accomplished executive who has an outstanding record of success in leading
complex global organizations and brings to this position a proven reputation of
operational excellence and global execution. I will remain fully engaged as
Chairman of the Board and look forward to continuing to work with Jim and the
Team.

We greatly value and need the talents and hard work of all our employees as we
seek continued success in a global healthcare industry marked by continuing
dramatic transformation and realignment. Fundamental issues involving health
policy, consolidation, cost, quality and organization of health providers
continue to drive significant change in how healthcare is delivered and paid for
throughout the world. None of these issues will be completely resolved in the
near future. In fact, emerging issues, including the organization of payers
along with providers, increased consumer involvement in healthcare decision
making, and medical disease management, will also grow in importance.

All of these issues will challenge the conventional wisdom of how we compete
successfully in our segment of the healthcare business. For example, succeeding
in today's economic climate requires us to assess the reimbursement situation
early in the new product development process and, based on this assessment,
bring the right clinical and economic information to healthcare purchasers. As a
result, we have strengthened our core competencies in this area enabling us to
better optimize the market adoption of our new technologies. Investment in this
new competency is symbolic of our commitment to listen to our customers and our
willingness to be open to change.

Another example of this commitment is our creation of an advisory council
comprised of opinion leaders representing major segments of the healthcare
industry. The primary goal of this group is to provide a platform for
constructive dialogue among healthcare leaders who have a vested interest in
clarifying complex issues and identifying potential solutions to healthcare
dilemmas. These are but two examples of the many ways in which we are responding
to a rapidly changing landscape to ensure we remain a relevant force in the
healthcare arena.

THE POWER OF ONE

This letter reports some of our achievements, calls for a strong commitment to
improvement and emphasizes the need to rebalance our vision with renewed ability
to execute to plan. We must be attentive to our own values and mindful of the
financial health of our company. This will require that we continue making tough
decisions in the year ahead, and we will do it. Our long-term strategic vision
is sound, and we have a strong, committed management team. We bring a robust
tradition of innovation, clearly defined values and a true "can do" spirit to
the tasks at hand.

Our biggest asset, however, remains the cadre of immensely talented, dedicated
and hardworking men and women who are Boston Scientific's employees. Challenges
are not new to them, as their history of pioneering accomplishments affirms. The
extra effort of a single employee to execute better may seem inconsequential;
multiplied by 12,000, the power of one becomes the power of Boston Scientific
and the promise of our future. It has been that way from the beginning.



                                             Respectfully,
                                             
                                             /s/ Pete M. Nicholas

             1. PAYING EQUAL ATTENTION TO CRITICAL SUCCESS FACTORS
           REQUIRED TO MAINTAIN A BEST-IN-CLASS LEADERSHIP POSITION.

            As Boston Scientific has grown, it has changed. Our much
        larger global enterprise demands different processes from those
         that served us well in the past. Employees who have joined the
        company in the last year or two may not have fully internalized
       the values that guide our organization. This is normal. Growth is
          organic. It means change. It means constantly redefining who
         we are, what we stand for, what we want to accomplish and how
           we will do so. It means constantly striving to balance the
         factors on which our success depends. Our strength lies in our
       vision.and in our ability to execute it. It lies in the spirit of
          innovation which permeates our culture and in having people
             who can translate that vision and spirit into reality.
                      The four words on the front cover -
                     Vision, Execution, Innovation, People
                                - tell a story.
                   This annual report is about the process of
            defining what those words mean to us today and about the
              process of balancing them for continued success in a
                        changing and challenging world.

(UNWAVERING) MISSION AND VISION

Since our founding in 1979, our mission has been to improve the quality of
patient care and productivity of healthcare delivery. It is a goal that is as
relevant today as it was 20 years ago. Our vision-to become the biggest, the
best and the fastest medical device company in the world-derives its meaning
from our mission. Stripped of their strategic context, these are merely business
buzzwords; within the context of our mission, however, they define what we must
be in order to fully achieve that mission: a supplier of the best technology and
products that enable our physician customers to deliver the most effective
diagnosis and treatment, with the greatest clinical and economic outcomes, to
the patients they treat. Our vision continues to drive our success.

(VALUES) A VISION WITH INTEGRITY

The vitality of our vision depends on the values it embodies. Values provide
integrity and enable us--as individuals and as a corporation--to achieve amazing
things. It is fair to say that we have influenced how healthcare is delivered
with our pioneering efforts in less invasive medicine. And the values that made
this possible--willingness to take risks, a strong commitment to thinking like
our customers and working hard on their behalf, for instance--continue to guide
our efforts. They are also the same values that have helped to make the
companies we have acquired successful. As we continue to focus on integrating
our acquisitions into a unified organization, our shared value system forms a
foundation on which we will build an even stronger company.

Our values are timeless. The first solo circumnavigation of the globe in 1898 by
Joshua Slocum was possible because of his ability to persevere, to strike out on
his own, and to trust others to help him achieve his goal. A century later, the
same values enabled us to chart a groundbreaking course in less invasive
medicine. The image of Slocum's sloop, Spray, in a balloon catheter, reminds us
of these shared values and symbolizes the seeming impossibility of both putting
a ship in a bottle and performing surgery through minute openings with
sophisticated instruments. It is a fitting symbol for our company.

(RESPONSIVE) REDEFINING HOW VISION BECOMES REALITY

As constant as our vision is, it must also be responsive to changing times. We
are no longer a lone pioneer on the frontier of less invasive medicine, but a
leader in a highly competitive and rapidly evolving healthcare landscape. We
have responded proactively with the concept of Strategic Mass--developing
breadth and depth through external event strategies and internal development to
reinforce our leadership position in our chosen fields. Now we must assimilate
the people, cultures, processes and strengths of our acquisitions, and, at the
same time, continue to drive and manage the internal growth spurred by the
success of our unparalleled product portfolio. Will Boston Scientific remain
unchanged? No. We will all change...together.

[GRAPHIC]

While we must focus on performing basic business functions superbly, we must not
lose sight of maintaining close relationships with our physician customers and
responding to their needs. The reality of our vision is validated by the smile
of a child whose physician asked us for help in a time of need. Kimberly
Stuntzner (left) received a compassionate use of our Wallgraft(R) stent. The
Wallgraft stent was used to hold open her pulmonary artery while doctors
repaired a large pseudo aneurysm that threatened her life.

(BALANCE) VISION AND EXECUTION

Vision demands execution. As strong and inspiring as the Boston Scientific
vision is, it depends on Boston Scientific employees to make it happen. This is
not a lofty, esoteric event; it is performing daily tasks consistently
well--developing and delivering products where and when our customers need them,
continuing to seek and achieve manufacturing efficiencies and superior quality.
It demands relentless attention to detail.


(FUNDAMENTALS) FOCUS THROUGH TASK FORCES

We continue to change and improve. After four years and $6 billion in
acquisitions, we are intently focused on integrating our operations and bringing
both costs and the physical organization into better alignment. We are
developing the world class systems and processes befitting a worldwide
enterprise. Our awareness of what we need to do has resulted in establishing
four task forces, each charged with improving our execution in a
mission-critical area: supply chain, quality, innovation and organizational
development. Their work has begun, and the benefits, such as those offered by
improvements in supply chain management achievable with the installation of our
new global information system, are beginning to be felt.


(SPECIFICS) TACKLING THE ISSUES

Some issues are strictly internal-improving processes or realizing our goal of
being able to deliver any product anywhere we operate within one day. To gain
this efficiency, we have integrated our customer fulfillment centers into four
primary locations around the world capable of handling the increased product and
transactional volume driven by our growth. Our ability to integrate the entire
Schneider European distribution network in 68 days into our facility in Beek,
the Netherlands, depended on our global information system. It exemplifies the
kind of speed, power and flexibility for which we are striving throughout the
organization.

Other opportunities, such as reimbursement and outcomes planning, relate to our
external environment. It is no longer enough for new products to be better; they
must also be more cost-effective. We have taken a proactive approach to this by
internally establishing a strong team focused exclusively on building the
economic case for new products and gathering the data to support outcomes and
improved treatment claims.

Boston Scientific employee Dr. Sujha Subramanian and Dr. James Spies of
Georgetown University Medical Center are studying the potential advantages of a
minimally invasive procedure, uterine artery embolization (UAE), for treating
uterine fibroid tumors. UAE may offer a faster, less traumatic and easier to
perform procedure than traditional surgical treatment. But for women who hope to
have children, its biggest benefit is that it is a therapy that preserves
fertility. The efforts of Drs. Spies and Subramanian today are intended to
facilitate market acceptance of the procedure and allow Boston Scientific to
apply an existing technology that offers both physician and patient a less
invasive alternative to surgery.

(STRENGTH) EXECUTION AND INNOVATION

Boston Scientific was born and continues to grow on the strength of its ability
to innovate. Today, we continue to demonstrate our leadership in this arena with
our steady introduction of improvements to existing products, our introduction
of new devices and our investment in technologies for the future. Much of this
work is the direct outgrowth of our close relationships with physicians whose
specific needs often provide the impetus for new products. But it is not enough.
By extending our emphasis on execution to the actual process of innovation, we
can improve speed to market, focus on the highest potential products and
positively influence the lives of more people.

(FOCUS) MANAGING PROJECTS, SETTING PRIORITIES

Melding execution and innovation is the mandate of the Innovation Task Force.
Like the other task forces, its membership crosses disciplines and brings
together people from all divisions to develop a common approach to product
development that will be understood by everyone and will help us to leverage
skills, resources and knowledge across the corporation. Its goal is to improve
how we manage both individual research projects and our entire research
portfolio. One aspect of this effort is already being implemented. Boston
Scientific/Vascular has recognized the challenge and has developed a new design
control and quality training program to drive innovation and excellence in the
concept, development and launch phases of product development execution. These
types of efforts, and others, are expanding throughout the company.

(LEADERSHIP) EXPLORING NEW FRONTIERS

Worldwide, we have approximately 2,500 patent applications pending and our
current research efforts will undoubtedly bring this number even higher. In the
highly competitive coronary stent market, we enjoy a commanding presence. In
1998, in partnership with Medinol Ltd., we launched the NIR(R) stent in the
United States and Japan. The NIR(R) stent has rapidly ascended to a leadership
position. Also in 1998, we were the first to offer in the United States a
self-expanding coronary stent, the Radius(TM) stent, and followed up with a
second, the Magic WALLSTENT(R) stent system.

Our innovative work in interventional neuroradiology is less well known, but no
less important. Devices such as the Tracker(R) Excel(TM) and Renegade(TM)
microcatheters make it possible to track tortuous neurovasculature and treat
diseases in the brain. And we are breaking new ground in other areas. Boston
Scientific/Microvasive Urology is exploring and investing in fields such as
brachytherapy, which eliminates multiple beam radiation treatment by implanting
radioactive pellets or "seeds" to treat prostate cancer today and perhaps other,
localized cancers tomorrow. In the field of electrophysiology, Boston
Scientific/EP Technologies is investigating a new Loop catheter that uses
radiofrequency energy to treat atrial fibrillation. Atrial fibrillation, an
irregular heartbeat, affects approximately 5 million people worldwide and is a
leading cause of stroke. Our acquisition of CardioGene Therapeutics, Inc. puts
us on the frontier of using gene therapy to stimulate the growth of new blood
vessels and tissue. These technologies, and others in our robust pipeline,
provide great momentum for the Boston Scientific vision and for less invasive
medicine in the years to come.

(INTEGRATION) DIVERSITY AND UNITY

Our employees bring a wealth of diverse skills and knowledge that will be
essential to our future success. Regardless of where within the corporation they
work, Boston Scientific employees are people of commitment, and we appreciate
the divisional loyalties they hold. At the same time, we are focused on becoming
one company with common values and a common vision. Only in this way can we
fulfill our promise as a corporation and our commitment to providing growth
opportunities for our employees.

[GRAPHIC]

(TASK FORCE) DEVELOPING THE ORGANIZATION

The appointment of the Organizational Development Task Force testifies to the
urgency and importance of having an enterprise-wide system for ensuring the
availability of people at all levels with the right skills and experience to
manage our business and fuel our future growth. There is no more important task
in the corporation than getting people to their greatest potential.

We took a significant interdivisional first step in formulating a set of
leadership competencies that define the skills and abilities we need to develop
in all employees at all levels of the organization moving forward. Communicating
this framework, essentially the new foundation of our people systems, and
implementing developmental solutions to support it, are major endeavors for the
immediate future, along with the formulation of functional competencies that
will help define our employee development requirements.

(TEAMWORK) THE POWER OF ONE

One need not look far to find people throughout our organization who embody the
traits we value. Some are experienced professionals like Pam Jerdee. After
working in sales and training for Medi-tech, Microvasive Urology, Microvasive
Endoscopy and Corporate Sales, who better than Pam to now head our college
recruiting program and share our values with prospective employees? Others are
new employees, like engineer Deanna Capobianco, who volunteered to help Pam with
recruitment because she is energized by the Boston Scientific mission and eager
to share her enthusiasm with others.

Teamwork is an attribute we value and want to foster further in both
cross-divisional and cross-functional ways. For example, it takes many people to
develop, manufacture and distribute our controlled radial expansion (CRE(TM))
balloon dilators. This Microvasive Endoscopy product dramatically improves
physicians' ability to control placement, inflation and dilatation of the
balloon and minimize patient trauma while treating strictures throughout the
gastrointestinal tract. Members of the CRE dilator team cross all functions,
from research and development engineers to product managers, sales
representatives, and those responsible for the actual manufacture of the device.
The combination of their individual efforts generates a powerful force able to
achieve great things.

We also need more people capable of working across the organization, like Bob
Skribiski, Principal Engineer in our Corporate Technology department. Bob was
charged with the task of establishing a cross-divisional team that examines and
encourages communication with various technology and engineering staffs. Bob
enlisted technical personnel from the divisions and the result has been a team
that shares a common approach to engineering ideas, tooling and material
resources so all can do their jobs more efficiently and effectively. In
addition, new materials and processes are quickly communicated across divisional
and product lines, keeping the team poised for superior performance.

We can manufacture products, and we can develop programs to improve the skills
and value of our employees, but there is one thing we cannot manufacture:
enthusiasm and dedication. These come from within, and it is through the renewed
commitment and effort on the part of every Boston Scientific employee that we
will achieve our mission.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
- -------------------

RESULTS OF OPERATIONS

On September 10, 1998, the Company consummated its acquisition of Schneider
Worldwide (Schneider), formerly a member of the Medical Technology Group of
Pfizer Inc., for $2.1 billion in cash. The acquisition was accounted for using
the purchase method of accounting. The consolidated financial statements include
Schneider's operating results from the date of acquisition.

YEARS ENDED DECEMBER 31, 1998 AND 1997

Net sales increased 22% in 1998 to $2,234 million from $1,831 million in 1997.
Without the impact of foreign currency exchange rates on translation of
international revenues, net sales for 1998 increased 25%. International sales
during 1998 were negatively impacted compared to 1997 by approximately $47
million of unfavorable exchange rate movements caused primarily by the
strengthening of the United States (U.S.) dollar versus the Japanese yen. Net
income for the year ended December 31, 1998, excluding merger-related and
special charges, was $262 million or $0.66 per share (diluted) compared to $266
million or $0.67 per share in 1997. The Company for 1998 reported a net loss of
$264 million or $0.68 per share (diluted), including merger-related and special
charges of $527 million, net of tax, as compared to 1997 net income of $110
million, or $0.28 per share, including merger-related and special charges of
$156 million, net of tax.

U.S. revenues increased approximately 30% from 1997 to $1,394 million in 1998,
while international revenues increased approximately 11% from 1997 to $840
million in 1998. U.S. sales as a percentage of worldwide sales increased from
59% in 1997 to 62% in 1998. Worldwide vascular and nonvascular sales increased
25% and 13%, respectively, from 1997 to 1998. The increases in U.S. sales as a
percentage of worldwide sales and in vascular sales were primarily attributable
to the Company's 1998 third quarter introduction of U.S. coronary stents. U.S.
coronary stent revenues, primarily sales of the NIR(R) stent, were approximately
$211 million during the second half of 1998. Worldwide NIR(R) coronary stent
sales as a percentage of worldwide sales were approximately 13% in 1998 and
could exceed 20% during 1999. The NIR(R) coronary stent is supplied by Medinol
Ltd. (Medinol) and unforeseen delays, stoppages or interruptions in the supply
and/or mix of the NIR(R) stent could adversely affect the operating results of
the Company.

On November 3, 1998, the Company announced it had detected the occurrence of
business irregularities in the operations of its Japanese subsidiary. The
irregularities detected involved shipments of products that were improperly
recorded as sales to the subsidiary's dealer network in Japan. The Company has
recently completed its investigation of the irregularities and believes that the
irregularities were limited to the operations of the Japan subsidiary. The
Company's financial statements reflect management's estimate of the timing and
impact of the Japan business irregularities.

Gross profit as a percentage of net sales was approximately 67.1% and 70.2%
during 1998 and 1997, respectively. As a result of multiple acquisitions, the
Company's supply chain has been weakened and there has been continued pressure
on gross margins, including write-downs for excess and obsolete inventory and
high manufacturing costs. During 1998, the Company initiated a full time global
program to focus on supply chain optimization. The program is designed to lower
inventory levels and the cost of manufacturing, improve absorption and minimize
inventory write-downs. By addressing the entire supply chain, including
application of lean manufacturing techniques, the Company seeks to return gross
margins to more acceptable levels and to improve working capital. The program
should be completed by the end of 1999.

The decrease in gross margins during 1998 compared to 1997 was also attributable
to a decline in average selling prices due to continuing pressure on healthcare
costs and increased competition, and the significant increase in sales of the
NIR(R) coronary stent which have lower gross margins than the corporate average.
As average selling prices for the NIR(R) stents fluctuate, the Company's cost to
purchase the stents will change because cost is based on a constant percentage
of average selling prices. In the third quarter of 1998, the Company provided
$31 million ($21 million, net of tax) for costs associated with the Company's
decision to voluntarily recall the NIR ON(TM) Ranger(TM) with Sox(TM) coronary
stent system in the U.S.

Success of the global supply chain initiative is critical to realizing improved
gross margins. In addition, gross margins could be significantly impacted by the
purchase price of NIR(R) coronary stents and the amount of NIR(R) coronary stent
sales as a percentage of worldwide sales.

Selling, general and administrative expenses as a percentage of net sales
decreased from 36% in 1997 to 34% in 1998, while increasing approximately $92
million from $663 million in 1997 to $755 million in 1998. The decrease as a
percent of sales is primarily attributable to the increase in net sales related
to the launch of coronary stents in the U.S. In addition, during the past three
years, the Company has expanded its direct sales presence in Europe and Emerging
Markets so as to be in a position to take advantage of market opportunities in
those regions. The costs of expansion have negatively impacted the Company's
operating margins. During the second half of 1998, the Company's rate of
investment slowed and the Company has begun to realize improved returns in
certain geographic regions. The Company believes that, during 1999, it will
continue to leverage its direct sales infrastructure.

Approximately $17 million of the 1998 increase in expense dollars is
attributable to results of Schneider operations from the date of acquisition
through December 31, 1998. In addition, the increase in expense dollars reflects
costs to operate the Company's new global information system and increased costs
of domestic distribution.

Amortization expense increased 63% from $32 million in 1997 to $53 million in
1998 and increased as a percentage of sales from 1.8% to 2.4% of net sales. The
increase is primarily a result of the amortization of intangibles related to the
purchase of Schneider from the date of acquisition through December 31, 1998.

Royalty expenses remained at approximately 1% of net sales while increasing 41%
from $22 million in 1997 to $31 million in 1998. The Company continues to enter
into strategic technological alliances, some of which include royalty
commitments.

Research and development expenses remained at 9% of net sales while increasing
20% from $167 million in 1997 to $200 million in 1998. Approximately $7 million
of the increase in 1998 is attributable to research and development of Schneider
from the date of acquisition through December 31, 1998. The increase in research
and development reflects increased spending on new product development programs
and regulatory and clinical research, and reflects the Company's continued
commitment to refine existing products and procedures and to develop new
technologies that provide simpler, less traumatic, less costly and more
efficient diagnosis and treatment. The trend in countries around the world
toward more stringent regulatory requirements for product clearance and more
vigorous enforcement activities has generally caused or may cause medical device
manufacturers to experience more uncertainty, greater risk and higher expenses.

The aggregate purchase price of the Schneider acquisition has been allocated on
a preliminary basis to the assets acquired and liabilities assumed based on
their estimated fair values at the date of acquisition. The estimated excess of
purchase price over the fair value of the net tangible assets acquired was
allocated to specific intangible asset categories with the remainder assigned to
excess of cost over net assets acquired. Core technology, developed technology,
assembled workforce, customer lists, trademarks and patents are being amortized
on a straight-line basis over periods ranging from 9 to 25 years, and the
estimated excess of cost over net assets acquired is being amortized on a
straight-line basis over 40 years. In addition, the Company recorded a $671
million charge ($524 million, net of tax) to account for purchased research and
development acquired. The valuation of purchased research and development
represents the estimated fair value related to incomplete projects. At the date
of the acquisition, the development of these projects had not reached
technological feasibility and the research and development in progress had no
alternative future uses. Accordingly, these costs were expensed as of the date
of acquisition.

The income approach was used to establish the fair values of the intangible
assets. This approach establishes the fair value of an asset by estimating the
after-tax cash flows attributable to the asset over its useful life and then
discounting these after-tax cash flows back to a present value. The discounting
process uses a rate of return commensurate with the time value of money and
investment risk factors. Accordingly, for the purpose of establishing the fair
value of each asset in the Schneider analysis, revenues for each future period
were estimated, along with costs, expenses, taxes and other charges. Revenue
estimates were based on estimates of relevant market sizes and growth factors,
expected trends in technology and the nature and expected timing of new product
introductions by the Company and its competitors. With respect to the value of
purchased research and development, the Company considered, among other factors,
the research and development project's stage of completion, the complexity of
the work completed to date, the costs already incurred, the projected costs to
complete, the contribution of core technologies and other acquired assets, the
projected introduction date and the estimated useful life. The respective
after-tax cash flows were then discounted back to present value using a
risk-adjusted discount rate. The discount rates used in the Schneider analysis
ranged from 16%-28% dependent upon the risk profile of the asset.

The Company believes that the assumptions used in the forecasts were reasonable
at the time of the acquisition. No assurance can be given, however, that the
underlying assumptions used to estimate expected project revenues, development
costs or profitability, or the events associated with such projects, will
transpire as estimated. For these reasons, among others, actual results may vary
from the projected results.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (CONTINUED)
- ---------------------

The in-process technology acquired in the Schneider acquisition consisted of 20
significant research and development projects, ranging in stage of completion
from 46% to 95%. One project reached completion in late 1998, while the others
are expected to reach completion in 1999, 2000 and 2001. New in-process
technologies include brachytherapy for the prevention of restenosis, devices for
the treatment of carotid disease, devices for the treatment of coronary artery
disease, devices for peripheral vascular disease, devices for aneurysmal disease
and devices for nonvascular disease. Remaining efforts to complete the projects
include product validation, the successful completion of clinical trials and
governmental regulatory approvals. Through the acquisition date, approximately
$63 million had been spent by Schneider on the in-process research and
development projects. The Company intends to incur in excess of $50 million,
related primarily to salaries, materials, clinical trials and regulatory costs,
to develop the in-process technology into commercially viable projects over the
next three years. The Company expects to begin to realize significant revenue
and cash flows from the in-process technology beginning in 1999.

Management expects to continue supporting these research and development efforts
and believes the Company has a reasonable chance of completing the in-process
technology. However, the development of the in-process technology is subject to
risks and uncertainties. These include the inherent difficulties in completing
the projects on a timely basis, potential changes in future target markets,
technology and governmental regulation, third party intellectual property, and
product introductions or other actions by competitors. If the projects are not
successfully developed, the Company may not realize the value assigned to the
in-process technology. In addition, the value of the other acquired intangible
assets may also become impaired.

The Company is in the process of implementing a rationalization plan established
after acquiring Schneider. The rationalization plan takes into consideration
duplicate capacity and opportunities for further leveraging of cost and
technology platforms. The Company's actions approved and committed to in the
fourth quarter of 1998 will result in the displacement in 1999 of approximately
2,000 current positions, over half of which are manufacturing positions. The
Company has decided to close five Schneider facilities, as well as transition
the manufacturing of selected Boston Scientific product lines to different
sites. The Company expects that approximately 1,000 positions will be added in
1999 as a result of the transition plan. The Company estimates that the costs
associated with these activities will be approximately $62 million, most of
which represent severance and related costs. Approximately $36 million of the
total has been capitalized as part of the purchase price of Schneider. The
remaining $26 million ($17 million, net of tax) has been charged to operations.
These actions are anticipated to result in annualized cost savings of
approximately $50 to $75 million. The rationalization plan also resulted in the
decision to expand, not close, a facility originally provided for in a 1997
merger-related charge; thus, in the fourth quarter, the Company reversed $21
million ($14 million, net of tax) of previously recorded merger-related charges.
The reversal also includes revised estimates of contractual commitment payments,
associated legal costs and other asset write-downs originally provided for in a
1997 merger-related charge. The Company will continue to challenge its plant
network strategy during 1999. In the second quarter of 1998, the Company
reorganized certain U.S. sales organizations differently than was originally
contemplated at the time of the Target Therapeutics, Inc. (Target) acquisition.
As a result, the Company reversed $20 million ($13 million, net of tax) of 1997
merger-related charges. In addition, the Company recorded purchased research and
development of approximately $11 million in connection with another acquisition
consummated during 1998 and $30 million ($20 million, net of tax) of year-end
adjustments related primarily to write-downs of assets no longer deemed to be
strategic.

As discussed previously, results for the year ended December 31, 1998 include a
provision of $31 million for costs associated with the Company's decision to
voluntarily recall the NIR ON(TM) Ranger(TM) with Sox(TM) coronary stent system
in the U.S. The Company is aware that the U.S. Department of Justice is
conducting an investigation of matters that include this recall. The Company is
cooperating fully in the investigation.

During 1997, the Company recorded merger-related charges of $146 million ($106
million, net of tax) primarily related to the Company's acquisition of Target,
purchased research and development of $29 million, net of tax, in conjunction
with accounting for its additional investment in Medinol and other strategic
investments, and a charge of $31 million ($21 million, net of tax) to reflect
the impact of implementing a new accounting standard. 1997 results also include
provisions related to inventory write-downs of $19 million ($13 million, net of
tax) and litigation-related reserves of $34 million ($23 million, net of tax).

Interest expense increased from $14 million in 1997 to $68 million in 1998. The
overall increase in interest expense is primarily attributable to a higher
outstanding debt balance, including the issuance of $2.1 billion in commercial
paper on September 10, 1998 to finance the acquisition of Schneider and the
issuance of $500 million in fixed rate debt securities during the first quarter
of 1998. Other income (expense), net, changed from income of less than $1
million in 1997 to expense of $5 million in 1998. The change is primarily
attributable to net gains on sales of equity investments in 1997 that were more
significant than in 1998.

The Company's effective tax rate, including the impact of special charges, was
approximately 39% in 1997 and 4% in 1998. Excluding these special charges, the
pro forma effective tax rate increased from approximately 32% during 1997 to 33%
during 1998. The increase is primarily attributable to a shift in the mix of
U.S. and international business. The effective rate for 1999 is expected to
increase slightly due to the continued shift in the geographic mix of the
Company's business.

The Company has substantially completed the integration of all mergers and
acquisitions consummated in 1996 and 1997. The Company expects to complete the
integration of Schneider by the end of 1999. Management believes it has
developed a sound plan for continuing and concluding the integration process,
and that it will achieve that plan. However, in view of the number of major
transactions undertaken by the Company, the dramatic change in the size of the
Company and the complexity of its organization resulting from these
transactions, management also believes that the successful implementation of its
plan presents a significant degree of difficulty. The failure to integrate these
businesses effectively could adversely affect the Company's operating results in
the near term, and could impair the Company's ability to realize the strategic
and financial objectives of these transactions.

Uncertainty remains with regard to future changes within the healthcare
industry. The trend towards managed care and economically motivated buyers in
the U.S. may result in continued pressure on selling prices of certain products
and resulting compression on gross margins. The U.S. marketplace is increasingly
characterized by consolidation among healthcare providers and purchasers of
medical devices that prefer to limit the number of suppliers from which they
purchase medical products. There can be no assurance that these entities will
continue to purchase products from the Company. In addition, international
markets are also being affected by economic pressure to contain reimbursement
levels and healthcare costs. The Company's ability to benefit from its
international expansion may be limited by risks and uncertainties related to
economic conditions in these regions, 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
political, regulatory or economic environment where the Company conducts
operations may have a material impact on revenues and profits. Although these
factors may impact the rate at which Boston Scientific can grow, the Company
believes that it is well positioned to take advantage of opportunities for
growth that exist in the markets it serves.

YEARS ENDED DECEMBER 31, 1997 AND 1996

Net sales increased 18% in 1997 to $1,831 million from $1,551 million in 1996.
International sales for the year were adversely impacted by changes in foreign
currency exchange rates. Without the impact of changes in exchange rates, net
sales for the year increased approximately 23%. Net income for the year ended
December 31, 1997, excluding merger-related and special charges, decreased
approximately 10% to $266 million from $295 million during the year ended
December 31, 1996.

In 1997, the Company recorded merger-related charges of $146 million ($106
million, net of tax) and purchased research and development of $29 million, net
of tax, and the Company recorded a charge of $31 million ($21 million, net of
tax) to reflect the impact of implementing an accounting standard issued in 1997
related to business process reengineering. 1997 results also include provisions
related to inventory write-downs of $19 million ($13 million, net of tax) and
litigation-related reserves of $34 million ($23 million, net of tax). During
1996, the Company recorded merger-related charges of $32 million ($29 million,
net of tax) and purchased research and development of $110 million ($99 million,
net of tax). Reported net income for 1997 was $110 million, or $0.28 per share
(diluted), as compared to $167 million, or $0.42 per share, for the prior year.

U.S. revenues increased approximately 16% from 1996 to $1,076 million in 1997,
while international revenues, increased approximately 20% from 1996 to $755
million in 1997. International sales as a percentage of worldwide sales
increased from 40% in 1996 to 41% in 1997. International sales during 1997 were
negatively impacted compared to 1996 by approximately $77 million of unfavorable
exchange rate movements caused primarily by the strengthening of the U.S. dollar
versus major European currencies and the Japanese yen. Worldwide vascular and
nonvascular sales increased 16% and 26%, respectively, from 1996 to 1997.

Gross profit as a percentage of net sales was approximately 70.2% and 72.4%
during 1997 and 1996, respectively. The decline in gross margins during 1997 is
primarily attributable to write-downs for excess and obsolete inventory and a
decline in average selling prices as a result of continuing pressure on
healthcare costs and increased competition. In addition, gross margins were
negatively impacted by the unfavorable foreign exchange rate movements discussed
above. The negative impact of the above conditions was partially offset by the
Company's U.S. cost containment programs and the positive gross margin impact of
selected new product offerings.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (CONTINUED)
- ---------------------

Selling, general and administrative expenses increased 35% from $492 million in
1996 to $663 million in 1997, and increased as a percentage of sales from 32% to
36% of net sales. The increase includes $34 million in litigation-related
reserves recorded in 1997. In addition, the Company continued to expand its
domestic and international sales and distribution organizations.

Amortization expense increased 37% from $24 million in 1996 to $32 million in
1997, and increased as a percentage of sales from 1.5% to 1.8% of net sales. The
increase in dollars is primarily a result of several strategic alliances
initiated by the Company during 1997.

Royalty expenses remained at approximately 1% of net sales while increasing 30%
from $17 million in 1996 to $22 million in 1997. The increase in overall royalty
expense dollars is due to increased sales and royalties due under several
strategic alliances that the Company initiated in 1997 and prior years.

Research and development expenses remained at approximately 9% of net sales
while increasing 24% from $135 million in 1996 to $167 million in 1997. The
increase in research and development dollars reflects increased spending in
regulatory, clinical research and various other product development programs,
and reflects the Company's continued commitment to refine existing products and
procedures and to develop new technologies that provide simpler, less traumatic,
less costly and more efficient diagnosis and treatment.

Interest and dividend income was $4 million as compared to $6 million in 1996.
The decrease is primarily attributable to a decrease in the Company's average
cash and marketable securities balance resulting from the use of cash to fund
the Company's working capital, finance several of the Company's recent
acquisitions and alliances and to repurchase the Company's common stock.
Interest expense increased from $12 million in 1996 to $14 million in 1997. The
overall increase in interest expense is primarily attributable to a higher
outstanding balance related to the Company's commercial paper borrowings. Other
income (expense), net, changed from expense of $5 million in 1996 to less than
$1 million of income in 1997. The change is primarily attributable to net gains
on sales of equity investments of approximately $11 million compared to net
gains of $1 million in 1996.

The Company's effective tax rate, including the impact of special charges, was
approximately 45% in 1996 and 39% in 1997. Excluding these special charges, the
pro forma effective tax rate improved from approximately 34% during 1996 to 32%
during 1997. The reduction in the Company's effective tax rate, excluding the
impact of special charges, is primarily due to increased business in lower tax
geographies and certain tax planning initiatives.

LIQUIDITY AND CAPITAL RESOURCES

Cash and short-term investments totaled $75 million at December 31, 1998
compared to $80 million at December 31, 1997. Cash flows provided by operating
activities increased from $80 million in 1997 to $258 million during 1998. Cash
used in investing and provided by financing activities during the same period
increased from $251 million to $2,225 million and $162 million to $1,977
million, respectively. The increases are primarily the result of financing the
Schneider acquisition with commercial paper and capital expenditures incurred to
expand the Company's manufacturing facilities. In addition, cash was provided by
the exercise of stock options. As a result, working capital decreased from $227
million at December 31, 1997 to current liabilities exceeding current assets by
$353 million at December 31, 1998.

Accounts receivable increased $172 million from December 31, 1997 to December
31, 1998. The increase is primarily attributable to recording approximately $65
million of Schneider accounts receivable as of the date of the acquisition, an
increase in U.S. sales in the second half of 1998 compared to the second half of
1997, and an increase in international sales to countries where healthcare
systems have longer payment terms. In addition to impacting selling prices, the
trend to managed care in the U.S. has also resulted in more complex billing and
collection procedures. The Company's ability to effectively react to the
changing environment may impact its bad debt and sales return provisions in the
future. In addition, the deterioration in the Japan economy may impact the
Company's ability to collect its outstanding Japan receivables.

Inventory increased $70 million from December 31, 1997 to December 31, 1998. The
increase since December 31, 1997 is primarily attributable to recording $40
million of Schneider inventory as of the date of acquisition, continued stocking
of the NIR(R) stent in the U.S. and Japan and an increase in U.S. finished
goods. The Company is committed to purchase approximately $150 million of NIR(R)
stents through 1999. Excluding the impact of Schneider inventory acquired,
inventory has decreased since the second quarter of 1998. The Company expects
inventory levels to continue to decline in 1999 as the Company's new global
supply chain management system becomes fully operational. Successful
implementation of the Company's supply chain initiative is necessary to reduce
the Company's inventory to an acceptable level and to reduce manufacturing
costs.

In connection with the Schneider acquisition, the Company established $1.7
billion in additional revolving credit facilities. The Company's revolving
credit facilities (Facilities) now total $2.2 billion and consist of a $1.0
billion facility that terminates in June 2002 and $1.2 billion in 364-day
facilities that terminate in September 1999. The Company may extend the 364-day
revolving credit facilities for an additional 364 days

                                      F-6

under certain conditions. Use of the borrowings is unrestricted and the
borrowings are unsecured. Commercial paper is supported by the Facilities and
outstanding commercial paper reduces available borrowings under the Facilities.
The Facilities require the Company to maintain a specific ratio of consolidated
funded debt (as defined) to consolidated net worth (as defined) plus
consolidated funded debt. The ratio requirement is 70% through December 31, 1999
and 60% thereafter. As of December 31, 1998, the ratio was approximately 64%.
The Company currently intends to comply with the reduction in the ratio through
an equity issuance, as discussed below.

As noted, the Company financed the Schneider acquisition by issuing
approximately $2.1 billion in commercial paper. At December 31, 1998, the
Company had approximately $1.8 billion of commercial paper outstanding at a
weighted average interest rate of 6.23%. The Company expects a minimum of $800
million will remain outstanding through the next twelve months and, accordingly,
has classified this portion of borrowings as long-term at December 31, 1998.
During the first quarter of 1999, the Company refinanced substantially all of
its commercial paper with short-term borrowings under its Facilities due to the
limited market for its commercial paper. The variable interest rates on the
borrowings is approximately 5.75%. The Company intends to continue to borrow
under its Facilities until it is able to issue commercial paper at reasonable
rates.

In 1999, the Company intends to refinance a portion of the outstanding credit
facilities balance by raising more permanent financing through an issuance of
convertible securities and additional equity securities. In September 1998, the
Company filed a Public Registration Statement with the U.S. Securities and
Exchange Commission. At December 31, 1998, the Company had no outstanding
securities issued under this registration statement.

In March 1998, the Company issued $500 million of 6.625% debt securities (Debt
Securities) due March 2005 under a Public Debt Registration Statement filed with
the U.S. Securities and Exchange Commission. The Debt Securities are not
redeemable prior to maturity and are not subject to any sinking fund
requirements. A significant portion of the net proceeds from the sale of the
Debt Securities (approximately $496 million) was used for repayment of
indebtedness under the Company's commercial paper program.

During March 1998, the Company borrowed 1.2 billion yen (the equivalent of
approximately $11 million) under a financing arrangement with a Japanese bank at
a fixed interest rate of 2.1%. The term of the borrowing extends through 2012.

At December 31, 1998, the Company had an additional 6 billion Japanese yen
borrowings (approximately $53 million) outstanding with a syndicate of Japanese
banks. The interest rate on the borrowings is 2.47%. The borrowings are payable
in 2002.

The Company had uncommitted Japanese credit facilities with several Japanese
banks to provide for borrowings and promissory notes discounting of up to 7.5
billion Japanese yen (approximately $66 million). At December 31, 1998, there
were no borrowings under these facilities and approximately $61 million of
receivables were discounted at average interest rates of approximately 1.5%.

Since early 1995, the Company has entered into several transactions involving
acquisitions and alliances, certain of which have involved equity investments.
As the healthcare environment continues to undergo rapid change, management
expects that it will continue to focus on strategic initiatives and/or make
additional investments in existing relationships, although management does not
expect that such investments will be significant during 1999. As of December 31,
1998, the Company's cash obligations required to complete the balance of the
Company's initiatives to integrate businesses related to its mergers and
acquisitions and its fourth quarter rationalization plan are estimated to be
approximately $70 million. In addition, the Company has outstanding $140 million
of acquisition-related cash obligations. Substantially all of these cash outlays
will occur during 1999. Further, the Company expects to incur capital
expenditures of approximately $130 million during 1999.

The Company expects that its cash and cash equivalents, marketable securities,
cash flows from operating activities, proceeds from the issuance of debt and
equity securities discussed previously and borrowing capacity will be sufficient
to meet its projected operating cash needs, including integration costs through
the end of 1999. As noted, the Company has $1.2 billion of 364-day credit
facilities that expire in September 1999. An extension of these facilities will
be needed if the Company does not obtain additional financing through an equity
offering or other means. The Company intends to issue equity and other
securities, but there are no assurances that additional financing can be or will
be obtained.

YEAR 2000 READINESS

The inability of business processes to continue to function correctly after the
beginning of the Year 2000 could have serious adverse effects on companies and
entities throughout the world. The Company has undertaken a global effort to
identify and mitigate Year 2000 issues in its information systems, products,
facilities and suppliers.

The Company established a multidisciplinary Year 2000 Task Force in 1998,
comprised of management from each of the Company's principal functional areas,
including Finance, Information Technology, Regulatory Affairs, Customer Service,
Manufacturing, Distribution, Purchasing, Facilities, Legal and Communications. A
core team and a program management office has also been established for
coordinating and

Management's Discussion and Analysis of Financial Condition and
Results of Operations (continued)
- ---------------------

tracking all Year 2000 issues. This office is comprised of Company management
and staff and representatives of an experienced Year 2000 consulting firm. These
efforts report directly to members of the Company's Executive Committee.

An independent consulting firm has been working with the Company for over two
years to implement a global information system that is designed to be Year 2000
compliant. In addition to the Company's information systems project, other
internal systems are being addressed largely through the replacement and testing
of much of the Company's older systems. The efforts are both company-wide and
site specific, spanning the range from the Information Technology department
systems to manufacturing operations (including production facilities, support
equipment, and process control) and infrastructure technologies.

The vast majority of the Company's products do not perform date-sensitive
operations and are therefore unaffected by Year 2000 issues. Steps have been
taken to correct non-compliance which affects the functional performance of the
few remaining products.

Through December 31, 1998, the Company has expended in excess of $100 million to
implement and operate a Year 2000 compliant global information system, and other
costs relating to Year 2000 compliance. The Company does not anticipate that
additional compliance costs will have a material impact on its business
operations or its financial condition.

The Company relies on third party providers for services such as
telecommunications, Internet service, utilities, certain product components and
other key services. Interruption of those services due to Year 2000 issues could
affect the Company's operations. The Company has initiated an evaluation of the
status of third party service providers' compliance efforts and of alternative
and contingency requirements. While approaches to reducing risks of interruption
of business operations vary by business unit, options include identification of
alternative service providers available to provide such services if a service
provider fails to become Year 2000 compliant within an acceptable time frame.
Based on the Company's evaluation to date, management believes that in most
cases redundant capacity exists at the supplier or that alternative sources of
supply are available or could be developed within a reasonable amount of time
should compliance become an issue for individual suppliers.

The Company believes that its Year 2000 program will identify and correct all
material non-compliant systems and operations before the end of 1999. Third
party service providers are being assessed and the Company expects to have
contingency plans that will avoid failures having a material effect on the
Company's business operations or financial condition in place before the end of
1999.

There can be no assurance that the Company's Year 2000 program will identify and
correct all non-compliant systems of the Company and its third party service
providers or that any such failure will not have a material effect on the
Company's business operations or financial condition.

MARKET RISK DISCLOSURES

In the normal course of business, the Company is exposed to market risk from
changes in interest rates and foreign currency exchange rates. The Company
addresses these risks through a risk management program that includes the use of
derivative financial instruments. The use of derivative financial instruments
are initiated within the guidelines of documented corporate risk management
policies. The Company does not enter into any derivative transactions for
speculative purposes.

The Company's floating and fixed rate debt obligations are subject to interest
rate risk. A 100 basis point increase in interest rates related to the Company's
floating rate borrowings, assuming the amount borrowed remains constant, would
result in an annual increase in the Company's then current interest expense of
approximately $18 million. The Company intends to refinance a portion of its
floating rate borrowings through a combination of issuance of convertible
securities and additional equity securities, which are subject to market risk. A
100 basis point increase in interest rates related to the Company's fixed
long-term debt would not result in a material change in its fair value.

The Company enters into foreign exchange contracts to hedge foreign currency
transactions on a continuing basis for periods consistent with commitments,
generally one to six months. The Company does not engage in speculation. The
Company's foreign exchange contracts should not subject the Company to material
risk due to exchange rate movements because gains and losses on these contracts
should offset losses and gains on the assets and liabilities being hedged. The
Company had spot and forward foreign exchange contracts outstanding in the
notional amounts of $230 million and $177 million as of December 31, 1998 and
1997, respectively. Although the Company engages in hedging transactions that
may offset the effect of fluctuations in foreign currency exchange rates on
foreign currency denominated assets and liabilities, financial exposure may
nonetheless result, primarily from the timing of transactions and the movement
of exchange rates. The short-term nature of these contracts has resulted in
these instruments having insignificant fair values at December 31, 1998.

A sensitivity analysis of changes in the fair value of foreign currency exchange
contracts outstanding at December 31, 1998 indicates that, if the U.S. dollar
uniformly weakened by 10% against all currencies, the fair value of these
contracts


                 BOSTON SCIENTIFIC CORPORATION AND SUBSIDIARIES
                                      F-8


<PAGE>   27


would decrease by $11 million. While these hedging instruments are subject to
fluctuations in value, such fluctuations are generally offset by changes in the
value of the underlying exposures being hedged. In addition, unhedged foreign
currency balance sheet exposures as of December 31, 1998 are not expected to
result in a significant loss of earnings or cash flows. As the Company has
expanded its international operations, its sales and expenses denominated in
foreign currencies have expanded and that trend is expected to continue.
Therefore, most international sales and expenses have been, and are expected to
be, subject to the effect of foreign currency fluctuations and these
fluctuations may have an impact on margins. The Company's sensitivity analysis
of the effects of changes in foreign currency exchange rates does not factor in
a potential change in sales levels or local currency selling prices.

EURO CONVERSION

On January 1, 1999, eleven of the fifteen member countries of the European Union
established fixed conversion rates between their existing sovereign currencies
and the euro. The participating countries agreed to adopt the euro as their
common legal currency on that date. Fixed conversion rates between these
participating countries' existing currencies (the legacy currencies) and the
euro were established as of that date. The legacy currencies are scheduled to
remain legal tender as denominations of the euro until at least January 1, 2002
(but not later than July 1, 2002). During this transition period, parties may
settle transactions using either the euro or a participating country's legacy
currency. The Company is addressing the potential impact resulting from the euro
conversion, including adaptation of information technology systems, competitive
implications related to pricing and foreign currency considerations.

Management currently believes that the introduction of the euro will not have a
material impact related to the adaptation of information technology systems or
foreign currency exposures. The increased price transparency resulting from the
use of a single currency in the eleven participating countries may affect the
ability of the Company to price its products differently in the various European
markets. A possible result of this is price harmonization at lower average
prices for products sold in some markets. However, uncertainty exists as to the
effects the euro will have on the marketplace.

LITIGATION

The Company is involved in various lawsuits, including patent infringement and
product liability suits, from time to time in the normal course of business. In
management's opinion, the Company is not currently involved in any legal
proceeding other than those specifically identified in the notes to consolidated
financial statements which, individually or in the aggregate, could have a
material effect on the financial condition, operations and cash flows of the
Company. The Company believes that it has meritorious defenses against claims
that it has infringed patents of others. However, there can be no assurance that
the Company will prevail in any particular case. An adverse outcome in one or
more cases in which the Company's products are accused of patent infringement
could have a material adverse effect on the Company.

Further, product liability claims may be asserted in the future relative to
events not known to management at the present time. The Company has insurance
coverage which management believes is adequate to protect against such product
liability losses as could otherwise materially affect the Company's financial
position.

purchase of Schneider; and (v) the timing, size and nature of strategic
initiatives available to the Company.

Several important factors, in addition to the specific factors discussed in
connection with such forward-looking statements individually, could affect the
future results of the Company and could cause those results to differ materially
from those expressed in the forward-looking statements contained herein. Such
additional factors include, among other things, future economic, competitive and
regulatory conditions, demographic trends, third-party intellectual property,
financial market conditions and future business decisions of Boston Scientific
and its competitors, all of which are difficult or impossible to predict
accurately and many of which are beyond the control of Boston Scientific.
Therefore, the Company wishes to caution each reader of this report to consider
carefully these factors as well as the specific factors discussed with each
forward-looking statement in this report and as disclosed in the Company's
filings with the Securities and Exchange Commission as such factors, in some
cases, have affected, and in the future (together with other factors) could
affect, the ability of the Company to implement its business strategy and may
cause actual results to differ materially from those contemplated by the
statements expressed herein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(NOTE A)

NOTE A - SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include the
accounts of Boston Scientific Corporation (Boston Scientific or the Company) and
its subsidiaries, substantially all of which are wholly-owned, and include the
results of EP Technologies, Inc. (EPT) and Target Therapeutics, Inc. (Target)
acquired in 1996 and 1997, respectively, accounted for as poolings-of-interests
for all periods presented. The statements also include the results of Symbiosis
Corporation (Symbiosis), beginning in March 1996, the results of Endotech, Ltd.
and MinTec, Inc., and certain related companies (Endotech/MinTec), beginning in
May 1996 and the results of Schneider Worldwide (Schneider), beginning in
September 1998. Investments in affiliates, representing 20% to 50% of the
ownership of such companies, are accounted for under the equity method,
including the Company's investment in Medinol Ltd. (Medinol). Income recorded in
connection with these investments was not significant during the periods
presented. Investments in affiliates, representing less than 20% of the
ownership of such companies, are accounted for under the cost method.

ACCOUNTING ESTIMATES: The preparation of financial statements in conformity with
generally accepted accounting principles 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 financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

TRANSLATION OF FOREIGN CURRENCY: All assets and liabilities of foreign
subsidiaries are translated at the rate of exchange at year end while sales and
expenses are translated at the average rates in effect during the year. The net
effect of these translation adjustments is shown in the accompanying financial
statements as a component of stockholders' equity.

CASH AND CASH EQUIVALENTS: The Company considers all highly liquid investments
purchased with a maturity of three months or less to be cash equivalents.

SHORT-TERM INVESTMENTS: Short-term investments are recorded at fair value, which
approximates cost.

CONCENTRATION OF CREDIT RISK: Financial instruments that potentially subject the
Company to concentration of credit risk consist primarily of temporary cash and
cash equivalents, marketable securities, forward foreign exchange contracts and
accounts receivable. The Company invests its excess cash primarily in high
quality securities and limits the amount of credit exposure to any one financial
institution. The Company's investment policy limits exposure to concentration of
credit risk and changes in market conditions. The Company is exposed to
credit-related losses in the event of non-performance by counterparties to
financial instruments. The Company transacts forward foreign exchange contracts
with major financial institutions to limit its credit exposure.

The Company provides credit, in the normal course of business, primarily to
hospitals, private and governmental institutions and healthcare agencies and
doctors' offices. The Company performs ongoing credit evaluations of its
customers and maintains allowances for potential credit losses.

INVENTORIES: Inventories are stated at the lower of first-in, first-out cost or
market.

PROPERTY, PLANT AND EQUIPMENT: Property, plant, equipment and leaseholds are
stated at historical cost. Expenditures for maintenance and repairs are charged
to expense; betterments are capitalized. The Company provides for depreciation
and amortization by the straight-line method at rates which are intended to
depreciate and amortize the cost of these assets over their estimated useful
lives. Buildings and improvements are depreciated over a 15 to 40-year life;
equipment, furniture and fixtures are depreciated over a 2 to 12-year life.
Leasehold improvements are amortized on a straight-line basis over the shorter
of the useful life of the improvement or the term of the lease.

The Company capitalizes interest incurred on funds used to construct property,
plant and equipment. Interest capitalized was $4 million during 1998 and $5
million during 1997. The Company receives grant money equal to a percentage of
expenditures on eligible capital equipment which is recorded as deferred income
and recognized ratably over the life of the underlying assets. The grant money
would be repayable, in whole or in part, should the Company fail to meet certain
employment goals.

INTANGIBLE ASSETS: Intangible assets are amortized using the straight-line
method over the following lives: Patents and trademarks (3 - 20 years); Licenses
(2 - 20 years); Core and developed technology (3 - 25 years); Excess of cost
over net assets acquired (15 - 40 years); Other intangibles (various).

The Company examines the carrying value of its excess of cost over net assets
acquired and other intangible assets to determine whether there are any
impairment losses. If indicators of impairment were present in intangible assets
used in operations, and future cash flows were not expected to be sufficient to
recover the assets' carrying amount, an impairment loss would be charged to
expense in the period identified. No event has been identified that would
indicate an impairment of the value of material intangible assets recorded in
the accompanying consolidated financial statements.

INCOME TAXES: The Company utilizes the asset and liability method for accounting
for income taxes. Under this method, deferred tax assets and liabilities are
determined based on differences between financial reporting and tax bases of
assets and liabilities. Deferred tax assets and liabilities are measured using
the enacted tax rates and laws that will be in effect when the differences are
expected to reverse.

Taxes are not provided on unremitted earnings of subsidiaries outside the United
States (U.S.) where such earnings are permanently reinvested. At December 31,
1998, unremitted earnings of non-U.S. subsidiaries were $416 million. It is not
practical to estimate the amount of taxes payable on these foreign earnings.
Research and development tax credits are recorded as a reduction in income tax
expense in the year realized.

FORWARD FOREIGN EXCHANGE CONTRACTS: The Company enters into forward foreign
exchange contracts to hedge foreign currency transactions on a continuing basis
for periods consistent with commitments. The Company does not engage in
speculation. The Company's foreign exchange contracts do not subject the Company
to material balance sheet risk due to exchange rate movements because gains and
losses on these contracts offset losses and gains on the assets and liabilities
being hedged. During 1998, net foreign currency transaction and translation
gains (losses) that are reflected as other income (expense) on the Consolidated
Statements of Operations totaled approximately $2 million of net foreign
exchange gains compared to net foreign exchange losses of $4 million and $2
million in 1997 and 1996, respectively.

Although the Company engages in hedging transactions that may offset the effect
of fluctuations in foreign currency exchange rates on foreign currency
denominated assets and liabilities, financial exposure may nonetheless result,
primarily from the timing of transactions and the movement of exchange rates.
Further, any significant changes in the political, regulatory or economic
environment where the Company conducts international operations may have a
material impact on revenues and profits.

REVENUE RECOGNITION: The Company recognizes revenue from the sale of its
products when the products are shipped to its customers. The Company allows its
customers to return certain products for credit. The Company also allows
customers to return defective or damaged products for credit or replacement.
Accruals are made and evaluated for adequacy for all returns.

RESEARCH AND DEVELOPMENT: Research and development costs are expensed as
incurred.

STOCK COMPENSATION ARRANGEMENTS:The Company accounts for its stock compensation
arrangements under the provisions of APB Opinion No. 25, "Accounting for Stock
Issued to Employees", and intends to continue to do so. The Company has adopted
the disclosure-only provisions of Statement of Financial Accounting Standards
(SFAS) No. 123, "Accounting for Stock-Based Compensation".

ACCOUNTING CHANGE: In 1997, the Company implemented Emerging Issues Task Force
(EITF) No. 97-13 "Accounting for Costs Incurred in Connection with a Consulting
Contract or an Internal Project that Combines Business Process Reengineering and
Information Technology Transformation", the effect of which ($31 million or $21
million, net of tax) is reflected as a cumulative effect of change in accounting
in 1997.

NEW ACCOUNTING STANDARDS: In 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income" and SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information".

The Company has not yet adopted the American Institute of Certified Public
Accountants' Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities", which will require adoption in 1999, or SFAS No. 133, "Accounting
for Derivative Instruments and Hedging Activities", which will require adoption
in 2000. The Company is in the process of determining the effect of adoption of
these statements on its consolidated financial statements and related
disclosures but does not believe the impact will be significant.

NET INCOME PER COMMON SHARE: Net income (loss) per common share is based upon
the weighted average number of common shares, common share equivalents and the
dilutive effect of European put options, if applicable, outstanding each year.
The Company paid a two-for-one stock split on November 30, 1998. All historical
per share amounts have been restated to reflect the stock split.

RECLASSIFICATIONS: Certain prior years' amounts have been reclassified to
conform to the current years' presentation.

Long-term debt - floating rate                        800,000
</TABLE>

At December 31, 1998, the Company had approximately $1.8 billion of commercial
paper outstanding at a weighted average interest rate of 6.23% compared to $423
million at a weighted average interest rate of 6.46% at December 31, 1997. The
Company's commercial paper borrowings are supported by revolving credit
facilities with certain domestic and foreign financial institutions. At December
31, 1998, the revolving credit facilities totaled $2.2 billion. The credit
facilities consist of a $1.0 billion credit facility which terminates in June
2002 and $1.2 billion in 364-day facilities which terminate in September 1999
and can be extended for an additional 364 days under certain conditions. The
Company has the ability to refinance a portion of its short-term debt on a
long-term basis through its credit facilities and expects a minimum of $800
million will remain outstanding through the next twelve months and, accordingly,
the Company has classified this portion of borrowings as long-term at December
31, 1998. Under the revolving credit facilities, the Company has the option to
borrow amounts at various interest rates. Use of the borrowings is unrestricted
and the borrowings are unsecured. The revolving credit facilities require the
Company to maintain a specific ratio of consolidated funded debt (as defined) to
consolidated net worth (as defined) plus consolidated funded debt. In the first
quarter of 1999, the Company refinanced substantially all of the outstanding
commercial paper borrowings with proceeds of borrowings under the revolving
credit facilities. The Company had other outstanding bank obligations of $11
million and $24 million at December 31, 1998 and 1997, respectively, at weighted
average interest rates of 6.45% and 2.55%, respectively.

In March 1998, the Company issued $500 million of seven-year senior notes. The
senior notes bear a coupon of 6.625% payable semiannually, and are not
redeemable prior to maturity or subject to any sinking fund requirements.

During March 1998, the Company borrowed 1.2 billion Japanese yen (approximately
$11 million) at a fixed interest rate of 2.1% from a Japanese bank to finance a
facility construction project. The term of the borrowing extends through 2012.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(NOTE D CONTINUED TO NOTE G)
- ----------------------------

At December 31, 1998, the Company had an additional 6 billion Japanese yen
borrowings (approximately $53 million) outstanding with a syndicate of Japanese
banks. The interest rate on the borrowings is 2.47% and the borrowings are
payable in 2002.

The Company has uncommitted Japanese credit facilities with several Japanese
banks to provide for borrowings and promissory notes discounting of up to 7.5
billion Japanese yen (approximately $66 million). At December 31, 1998, there
were no borrowings outstanding under the Japanese credit facilities compared to
2.7 billion Japanese yen (approximately $21 million) at December 31, 1997.
During 1998, approximately $266 million of receivables were discounted through
promissory notes compared to $194 million during 1997. At December 31, 1998,
approximately $61 million of receivables were discounted at average interest
rates of approximately 1.5%.

In September 1998, the Company filed a $1.2 billion shelf registration with the
U.S. Securities and Exchange Commission under which the Company may from time to
time issue various equity and debt securities. At December 31, 1998, the Company
had no outstanding securities issued under this shelf registration.

Interest paid, including interest paid under capital leases and mortgage loans,
amounted to $65 million in 1998, $19 million in 1997, and $13 million in 1996.

NOTE F - FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by the Company in estimating its
fair value disclosures for financial instruments. However, considerable judgment
is required in interpreting market data to develop the estimates of fair value.
Accordingly, the estimates presented herein are not necessarily indicative of
the amounts that the Company could realize in a current market exchange.

CASH AND CASH EQUIVALENTS: The carrying amounts reported in the balance sheets
for cash and cash equivalents are valued at cost which approximates their fair
value.

INVESTMENTS: The fair values for marketable debt and equity securities are based
on quoted market prices when readily determinable.

COMMERCIAL PAPER AND BANK OBLIGATIONS: The carrying amounts of the Company's
borrowings under its commercial paper program and its financing agreements
approximate their fair value.

LONG-TERM DEBT: The fair value of the Company's fixed rate long-term debt is
estimated based on quoted market prices. The carrying amounts of the Company's
floating rate long-term debt approximate their fair value.

FORWARD FOREIGN EXCHANGE CONTRACTS: The fair values of forward foreign exchange
contracts are estimated based on the amount that the Company would receive or
pay to terminate the agreements at the reporting date. The Company had spot and
forward foreign exchange contracts outstanding in the notional amounts of $230
million and $177 million as of December 31, 1998 and 1997, respectively.

At December 31, 1998, the Company had U.S. tax net operating loss carryforwards
and research and development tax credits of approximately $14 million that will
expire periodically beginning in the year 2006. In addition, the Company had
foreign tax net operating loss carryforwards of approximately $15 million that
will expire periodically beginning in the year 2000. The Company established a
valuation allowance of $25 million for these carryforwards primarily

and 1997 mergers and acquisitions.

Income taxes paid amounted to $109 million in 1998, $89 million in 1997 and $85
million in 1996. The income tax provision (benefit) of the unrealized gain or
loss component of other comprehensive income (expense) was approximately $(11)
million, $1 million and $7 million for 1998, 1997 and 1996, respectively.

The Company is authorized to purchase on the open market up to approximately 40
million shares of the Company's common stock. Purchases will be made at
prevailing prices as market conditions and cash availability warrant. Stock
repurchased under the Company's systematic plan will be used to satisfy its
obligations pursuant to employee benefit and incentive plans. The Company did
not repurchase any shares of its common stock during 1998. Prior to 1998, a
total of 20 million shares of the Company's common stock was repurchased under
the program.

On August 27, 1998, the Company announced that its Board of Directors approved a
two-for-one stock split, to be effected in the form of a 100 percent stock
dividend. On November 4, 1998, the Company announced that its stockholders had
approved an amendment to the Company's certificate of

incorporation increasing the Company's authorized common stock from 300,000,000
shares to 600,000,000 shares and authorized preferred stock from 25,000,000 to
50,000,000 shares. The amendment allowed the two-for-one stock split announced
on August 27, 1998 to go forward. The stock split was paid on November 30, 1998
to stockholders of record as of November 13, 1998. All historical share and per
share amounts have been restated to reflect the stock split except for share
amounts presented in the Consolidated Balance Sheets and the Consolidated
Statements of Stockholders' Equity which reflect the actual share amounts
outstanding for each period presented.

NOTE I - STOCK OWNERSHIP PLANS

EMPLOYEE AND DIRECTOR STOCK INCENTIVE PLANS

Boston Scientific's 1992 and 1995 Long-Term Incentive Plans provide for the
issuance of up to 40 million shares of common stock. The terms of these two
plans are similar. The plans cover officers, employees and consultants of and to
the Company and provide for the grant of various incentives, including qualified
and non-qualified options, stock grants, share appreciation rights and
performance awards. Options granted to purchase shares of common stock are
either immediately exercisable or exercisable in installments as determined by
an appointed committee consisting of two or more non-employee directors (the
Committee), and, in the case of any qualified options, expire within ten years
from date of grant. In the case of qualified options, if an employee owns more
than 10% of the voting power of all classes of stock, the option granted will be
at 110% of the fair market value of the Company's common stock on the date of
grant and will expire over a period not to exceed five years.

The Committee may also make stock grants in which shares of common stock may be
issued to officers, employees and consultants at a purchase price less than fair
market value. The terms and conditions of such issuances, including whether
achievement of individual or Company performance targets is required for the
retention of such awards, are determined by the Committee. The Committee may
also issue shares of common stock and/or authorize cash awards under the
incentive plans in recognition of the achievement of long-term performance
objectives established by the Committee. Stock grants for 5,000 shares, 15,000
shares and 2,000 shares were issued to employees during 1998, 1997 and 1996,
respectively.

Boston Scientific's 1992 Non-Employee Directors' Stock Option Plan provides for
the issuance of up to 200,000 shares of common stock and authorizes the
automatic grant to outside directors of options to acquire 4,000 shares of
common stock generally on the date of each annual meeting of the Stockholders of
the Company. Options under this plan are exercisable ratably over a three-year
period and expire ten years from the date of grant.

Shares reserved for future issuance under all of the Company's plans totaled
approximately 42 million at December 31, 1998.

If the Company had elected to recognize compensation expense for the granting of
options under stock option plans based on the fair values at the grant dates
consistent with the methodology prescribed by SFAS No. 123, "Accounting for
Stock-Based Compensation", net income (loss) and earnings (loss) per share would
have been reported as the following pro forma amounts:

STOCK PURCHASE PLAN

Boston Scientific's Global Employee Stock Ownership Plan (Stock Purchase Plan)
provides for the granting of options to purchase up to 3 million shares of the
Company's common stock to all eligible employees. Under the Stock Purchase Plan,
each eligible employee is granted, at the beginning of each period designated by
the Committee as an offering period, an option to purchase shares of the
Company's common stock equal to not more than 10% of the employee's eligible
compensation. Such options may be exercised generally only to the extent of
accumulated payroll deductions at the end of the offering period, at a purchase
price equal to 85% of the fair market value of the Company's common stock at the
beginning or end of each offering period, whichever is less.

During 1998, approximately 380,000 shares were issued at $23.35 per share.
During 1997, approximately 240,000 shares were issued at prices ranging from
$23.45 to $24.33 per share, and, during 1996, approximately 240,000 shares were
issued at prices ranging from $18.06 to $19.71 per share. At December 31, 1998,
there were approximately 1.6 million shares available for future issuance.

During 1998, approximately 9 million stock options were not included in the
computation of earnings per share, assuming dilution, because they would have
been antidilutive. In addition, during 1998 and 1997, approximately 7 million
and 10 million stock options, respectively, were not included in the computation
of earnings per share, assuming dilution, because exercise prices were greater
than the average market price of the common shares.


NOTE K - COMMITMENTS AND CONTINGENCIES

On May 31, 1994, SCIMED Life Systems, Inc. (SCIMED), a wholly owned subsidiary
of the Company, filed a suit for patent infringement against Advanced
Cardiovascular Systems, Inc. (ACS), alleging willful infringement of two of
SCIMED's U.S. patents by ACS's RX ELIPSE(TM) PTCA catheter. The suit was filed
in the U.S. District Court for the Northern District of California seeking

Netherlands alleging ACS's MULTILINK(TM), RX ELIPSE, RX MULTILINK HP(TM) and RX
DUET(TM) catheters and stent delivery systems infringe one of the Company's
European patents. In this action, the Company requested relief covering The
Netherlands, the United Kingdom, France, Germany and Italy. A hearing on
cross-border jurisdiction will be held on March 12, 1999. A hearing on the
merits is set for November 5, 1999.

On January 13, 1999, SCIMED filed a suit for patent infringement against ACS,
Guidant and Guidant Sales Corporation alleging willful infringement of two of
SCIMED's U.S. patents by ACS's RX MULTILINK HP and RX DUET stent delivery
systems and one of SCIMED's U.S. patents by ACS's RX MULTILINK stent delivery
system. The suit was filed in the U.S. District Court for the Northern District
of California seeking monetary and injunctive relief. ACS has answered, denying
the allegations of the complaint.

On October 10, 1995, ACS filed a suit for patent infringement against SCIMED,
alleging willful infringement by SCIMED'S EXPRESS PLUS(TM) and EXPRESS PLUS
II(TM) PTCA catheters of four U.S. patents licensed to ACS. Suit was filed in
the U.S. District Court for the Northern District of California and seeks
monetary and injunctive relief. SCIMED has answered, denying the allegations of
the complaint. Trial is expected to begin in 1999.

On March 12, 1996, ACS filed two suits for patent infringement against SCIMED,
alleging in one case the willful infringement of a U.S. patent by SCIMED's
EXPRESS PLUS, EXPRESS PLUS II and LEAP(R) EXPRESS PLUS PTCA catheters, and in
the other case the willful infringement of a U.S. patent by SCIMED's BANDIT(TM)
PTCA catheter. The suits were filed in the U.S. District Court for the Northern
District of California and seek monetary and injunctive relief. SCIMED has
answered, denying the allegations of the complaints. Both trials are expected to
begin in 1999.

On September 16, 1997, ACS filed a suit for patent infringement against the
Company and SCIMED, alleging that SCIMED's REBEL(TM) PTCA catheter infringes two
U.S. patents licensed to ACS and one U.S. patent owned by ACS. Suit was filed in
the U.S. District Court for the Northern District of California seeking monetary
damages, injunctive relief and that the patents be adjudged valid, enforceable
and infringed. The Company and SCIMED have answered, denying the allegations in
the complaint. A trial date has not yet been set.

On August 12, 1998, ACS and an affiliate of ACS filed suit for patent
infringement against the Company and SCIMED alleging that the Company's NIR(R)
stent infringes five patents owned by ACS. The suit was filed in the U.S.
District Court for the Southern District of Indiana seeking injunctive and
monetary relief. The Company and SCIMED have answered, denying the allegations
of the complaint. A trial date has been set for February 22, 2000.

On March 25, 1996, Cordis Corporation (Cordis), a subsidiary of Johnson &
Johnson Company (Johnson & Johnson), filed a suit for patent infringement
against SCIMED, alleging the infringement of five U.S. patents by SCIMED's LEAP
balloon material, used in certain SCIMED catheter products, including SCIMED's
BANDIT and EXPRESS PLUS catheters. The suit was filed in the U.S. District Court
for the District of Minnesota and seeks monetary and injunctive relief. SCIMED
has answered, denying the allegations of the complaint. Trial is expected to
begin in 1999.

On March 17, 1997, the Company, through its subsidiaries, filed suit against
Cordis in France seeking a declaration of noninfringement for the Company's LEAP
balloon in relation to a European patent owned by Cordis. A hearing on the
pleadings is scheduled for May 11, 1999.

On July 18, 1997, Cordis filed a cross border suit in The Netherlands against
various subsidiaries of the Company, alleging that the LEAP balloon infringes
one of Cordis' European patents. In this action, Cordis requested expedited
relief, including an injunction, covering The Netherlands, Germany, France, the
United Kingdom and Italy. The court posed certain questions to the European
Patent Office (EPO). The Company appealed the court's decision to present
questions to the EPO. A hearing on the appeal was held June 16, 1998. In
November 1998, the Court of Appeals held that there was a "ready chance" that
the Cordis patent would be found invalid and dismissed the action.

On March 27, 1997, SCIMED filed suit for patent infringement against Cordis,
alleging willful infringement of several SCIMED U.S. patents by Cordis'
TRACKSTAR 14(TM), TRACKSTAR 18(TM), OLYMPIX(TM), POWERGRIP(TM), SLEEK(TM),
SLEUTH(TM), THOR(TM), TITAN(TM) and VALOR(TM) catheters. The suit was filed in
the U.S. District Court for the District of Minnesota, Fourth District, seeking
monetary and injunctive relief. The parties have agreed to add Cordis'
CHARGER(TM) and HELIX(TM) catheters to the suit. Cordis has answered, denying
the allegations of the complaint. Trial is expected to begin in 1999.

On March 13, 1997, the Company (through its subsidiaries) filed suits against
Johnson & Johnson (through its subsidiaries) in The Netherlands, the United
Kingdom and Belgium, and on March 17, 1997 filed suit in France, seeking a
declaration of noninfringement for the NIR(R) stent relative to two European
patents licensed to Ethicon, Inc. (Ethicon), a Johnson & Johnson subsidiary, as
well as a declaration of invalidity with respect to those patents. After a trial
on the merits in the United Kingdom during March 1998, the Court ruled on June
26, 1998 that neither of the patents is infringed by the NIR(R) stent, and that
both patents are invalid. Ethicon has appealed. On October 28, 1998, the
Company's motion for a declaration of noninfringement in France was dismissed
for failure to satisfy statutory requirements; the French invalidity suits were
not affected. The Company has appealed the dismissal, and a hearing is scheduled
for March 22, 1999.

On March 20, 21 and 22, 1997, the Company (through its subsidiaries) filed
additional suits against Johnson & Johnson (through its subsidiaries) in Sweden,
Italy and Spain, respectively, seeking a declaration of noninfringement for the
NIR(R) stent relative to one of the European patents licensed to Ethicon in
Sweden, Italy and Spain and a declaration of invalidity in Italy and Spain.

Ethicon and other Johnson & Johnson subsidiaries filed a cross-border suit in
The Netherlands on March 17, 1997, alleging that the NIR(R) stent infringes one
of the European patents licensed to Ethicon. In this action, the Johnson &
Johnson entities requested relief, including provisional relief (a preliminary
injunction), covering Austria, Belgium, France, Greece, Italy, The Netherlands,
Norway, Spain, Sweden, Switzerland and the United Kingdom. On April 2, 1997, the
Johnson & Johnson entities filed a similar cross-border proceeding in The
Netherlands with respect to a second European patent licensed to Ethicon.
Johnson & Johnson subsequently withdrew its request for cross-border relief in
the United Kingdom. In October, 1997, Johnson & Johnson's request for
provisional cross-border relief on both patents was denied by the Dutch court,
on the ground that it is "very likely" that the NIR(R) stent will be found not
to infringe the patents. Johnson & Johnson appealed this decision with respect
to one of the patents; the appeal has been denied on the ground that there is a
"ready chance" that the patent will be declared null and void. In January 1999,
Johnson & Johnson amended the claims of one of the patents, changed the action
from a cross-border case to a Dutch national action, and indicated its intent
not to pursue its action on the second patent. A hearing has been set for
March 26, 1999.

On May 6, 1997, Ethicon Endosurgery, Inc. sued the Company in Dusseldorf,
Germany, alleging that the Company's NIR(R) stent infringes one of Ethicon's
patents. On June 23, 1998, the case was stayed following a decision in an
unrelated nullity action in which the Ethicon patent was found to be invalid.

On June 16, 1997, the Company and SCIMED filed a suit against Johnson & Johnson,
Ethicon and Johnson & Johnson International Systems Co. in the U.S. District
Court for the District of Massachusetts seeking a declaratory judgment of
noninfringement for the NIR(R) stent relative to two patents licensed to Johnson
& Johnson and that the two patents are invalid and unenforceable. The Company
subsequently amended its complaint to add a third patent. Johnson & Johnson
answered, denying the allegations of the complaint, and counterclaiming for
patent infringement. In October 1997, Johnson & Johnson's motion to dismiss the
suit was denied. This action has been consolidated with the Delaware action
described below.

On August 22, 1997, Johnson & Johnson filed a suit for patent infringement
against the Company alleging that the sale of the NIR(R) stent infringes certain
Canadian patents owned by Johnson & Johnson. Suit was filed in the federal court
of Canada seeking a declaration of infringement, monetary damages and injunctive
relief. The Company has answered, denying the allegations of the complaint.

On October 22, 1997, Cordis filed a suit for patent infringement against the
Company and SCIMED alleging that the importation and use of the NIR(R) stent
infringes two patents owned by Cordis. The suit was filed in the U.S. District
Court for the District of Delaware seeking monetary damages, injunctive relief
and that the patents be adjudged valid, enforceable and infringed. The Company
and SCIMED have answered the complaint, denying Cordis' allegations. The
Massachusetts case described above has been consolidated with this action. A
trial date has been set for March 6, 2000.

On April 13, 1998, Cordis filed a suit for patent infringement against the
Company and SCIMED alleging that the Company's NIR(R) stent infringes a third
patent owned by Cordis. The suit was filed in the U.S. District Court for the
District of Delaware seeking injunctive and monetary relief. The Company and
SCIMED have answered, denying the allegations of the complaint. A trial date has
been set for March 6, 2000.

On August 13, 1998, Arterial Vascular Engineering, Inc. (AVE) filed a suit for
patent infringement against the Company and SCIMED alleging that the Company's
NIR(R) stent infringes two patents owned by AVE. The suit was filed in the U.S.
District Court for the District of Delaware seeking injunctive and monetary
relief. The Company and SCIMED have answered, denying the allegations of the
complaint. A trial date has not yet been set.

On December 15, 1998, the Company and SCIMED filed a cross-border suit against
AVE in The Netherlands alleging that AVE's AVE GFX(TM), AVE GFX 2(TM), AVE
LTX(TM) and USCI CALYPSO(TM) rapid exchange catheters and stent delivery systems
infringe one of the Company's European patents. In this action, the Company
requested relief covering The Netherlands, the United Kingdom, France, Germany
and Italy. A hearing is set for October 22, 1999.

On December 18, 1998, AVE filed a suit for patent infringement against the
Company and SCIMED alleging that the Company's MAXXUM(TM) and VIVA!(TM)
catheters infringe a patent owned by AVE. The suit was filed in the U.S.
District Court for the District of Delaware seeking injunctive and monetary
relief. The Company and SCIMED have answered, denying the allegations of the
complaint.

On April 5, 1995, C.R. Bard, Inc. (Bard) filed a lawsuit in the U.S. District
Court for the District of Delaware alleging that certain Company products,
including the Company's MaxForce TTS(TM) catheter, infringe a patent assigned to
Bard. Following a trial and jury verdict, on February 3, 1999 the court entered
a judgment that the Company infringed the Bard patent and awarded damages to
Bard in the amount of $10.8 million. The Company was also enjoined from selling
the product found to be infringing. The Company is appealing the judgment to the
Court of Appeals for the Federal Circuit. The Company no longer markets the
accused device.

On May 12, 1998, Bard filed a cross-border suit in The Netherlands against
various subsidiaries of the Company, alleging that the Company's VIVA!(TM) and
MAXXUM(TM) rapid exchange catheters infringe one of Bard's European patents. In
this action, Bard requested relief covering The Netherlands, Germany, France,
Spain and the United Kingdom. On February 16, 1999, the suit was withdrawn for
procedural reasons. The Company is aware that AVE, successor-in-interest to
Bard's cardiovascular business, could file a similar suit against the Company,
alleging infringement of the patent by one or more of the Company's products.

On March 7, 1996, Cook Inc. (Cook) filed suit in the Regional Court, Munich
Division for Patent Disputes, in Munich, Germany against MinTec, Inc. Minimally
Invasive Technologies alleging that the Cragg EndoPro(TM) System I and
Stentor(TM) endovascular device infringe a certain Cook patent. Since the
purchase of the assets of the Endotech/MinTec companies by the Company, the
Company has assumed control of the litigation. The defendant answered, denying
the allegations. A court-appointed technical expert has provided the court with
technical advice. A final hearing is scheduled to be held on May 12, 1999.

On June 30, 1998, Cook filed suit in the Regional Court, Dusseldorf Division
for Patent Disputes, in Dusseldorf,

Germany against the Company alleging that the Company's PASSAGER(TM) peripheral
vascular stent graft and VANGUARD(TM) endovascular aortic graft products
infringe the same Cook patent. A hearing date has been set for July 22, 1999.

On January 13, 1999, Medical Innovations Corporation (Innovations) filed a
lawsuit in the U.S. District Court for the District of Utah alleging that
certain Company products, including the Company's Ultratome(TM) XL sphinctertome
product, infringe two patents assigned to Innovations. The suit also includes a
claim of unfair trade practices. Innovations is seeking injunctive relief and
monetary damages for both claims. The Company is preparing an answer, denying
the allegations of the complaint.

On February 1, 1999, Hewlett-Packard Company filed a suit in the U.S. District
Court for the District of Massachusetts against the Company alleging violation
of the Sherman Antitrust Act and Massachusetts General Laws Chapter 93A and
breach of contract. The Company is preparing an answer, denying the allegations
of the complaint.

Beginning November 4, 1998, a number of shareholders of the Company, on behalf
of themselves and all others similarly situated, filed purported stockholders'
class action suits in the U.S. District Court for the District of Massachusetts
alleging that the Company and certain of its officers violated certain sections
of the Securities Exchange Act of 1934. The complaints principally allege that
as a result of certain accounting irregularities involving the improper
recognition of revenue by the Company's subsidiary in Japan, the Company's
previously issued financial statements were materially false and misleading. In
all, 16 purported class action suits have been filed. Plaintiffs have moved for
the appointment of lead plaintiffs and lead counsel. The Company and its
officers have not yet filed an answer, but intend to vigorously defend all
actions.

The Company is aware that the U.S. Department of Justice is conducting an
investigation of matters that include the Company's NIR ON(TM) Ranger(TM) with
Sox(TM) coronary stent delivery system which was voluntarily recalled by the
Company in October 1998 following reports of balloon leaks. The Company is
cooperating fully in the investigation.

The Company is involved in various other lawsuits from time to time. In
management's opinion, the Company is not currently involved in any legal
proceedings other than those specifically identified above which, individually
or in the aggregate, could have a material effect on the financial condition,
operations or cash flows of the Company.

The Company believes that it has meritorious defenses against claims that it has
infringed patents of others. However, there can be no assurance that the Company
will prevail in any particular case. An adverse outcome in one or more cases in
which the Company's products are accused of patent infringement could have a
material adverse effect on the Company.

At December 31, 1998 and 1997, the Company has accrued approximately $38 million
and $42 million, respectively, of litigation-related reserves to cover certain
costs of defense, settlement and damages.

Further, product liability claims may be asserted in the future relative to
events not known to management at the present time. The Company has insurance
coverage which management believes is adequate to protect against product
liability losses as could otherwise materially affect the Company's financial
position.

NOTE L - BUSINESS COMBINATIONS

On September 10, 1998, the Company consummated its acquisition of Schneider
Worldwide, formerly a member of the Medical Technology Group of Pfizer Inc., for
$2.2 billion, net of assets acquired and liabilities assumed. The acquisition
was accounted for using the purchase method of accounting. The consolidated
financial statements include Schneider's operating results from the date of
acquisition. The aggregate purchase price has been allocated on a preliminary
basis to the assets acquired and liabilities assumed based on their estimated
fair values at date of acquisition. The estimated excess of purchase price over
the fair value of net tangible assets acquired was allocated to specific
intangible asset categories as follows:

Core technology, developed technology, assembled workforce, customer lists,
trademarks and patents are being amortized on a straight-line basis over periods
ranging from 9 to 25 years and the excess of cost over net assets acquired is
being amortized on a straight-line basis over 40 years.

The Company recorded a $671 million ($524 million, net of tax) charge to account
for purchased research and development acquired. The valuation of purchased
research and development represents the estimated fair value related to
incomplete projects. At the date of the acquisition, the development of these
projects had not reached technological feasibility and the research and
development in progress had no alternative future uses. Accordingly, these costs
were expensed as of the date of acquisition.

The income approach was used to establish the fair values of the intangible
assets. This approach establishes the fair value of an asset by estimating the
after-tax cash flows attributable to the asset over its useful life and then
discounting these after-tax cash flows back to a present value. The discounting
process uses a rate of return commensurate with the time value of money and
investment risk factors. Accordingly, for the purpose of establishing the fair
value of each asset in the Schneider analysis, revenues for each future period
were estimated, along with costs, expenses, taxes and other charges. Revenue
estimates were based on estimates of relevant market sizes and growth factors,
expected trends in technology and the nature and expected timing of new product
introductions by the Company and its competitors. With respect to the value of
purchased research and development, the Company considered, among other factors,
the research and development project's stage of completion, the complexity of
the work completed to date, the costs already incurred, the projected costs to
complete, the contribution of core technologies and other acquired assets, the
projected introduction date and the estimated useful life. The respective
after-tax cash flows were then discounted back to present value using a
risk-adjusted discount rate. The discount rates used in the Schneider analysis
ranged from 16%-28% dependent upon the risk profile of the asset.

The Company believes that the assumptions used in the forecasts were reasonable
at the time of the acquisition. No assurance can be given, however, that the
underlying assumptions used to estimate expected project revenues, development
costs or profitability, or the events associated with such projects, will
transpire as estimated. For these reasons, among others, actual results may vary
from the projected results.

The following unaudited pro forma information presents a summary of consolidated
results of operations of the Company and Schneider as if the acquisition had
occurred at the beginning of each year presented, with pro forma adjustments to
give effect to amortization of intangibles, purchased research and development,
an increase in interest expense on acquisition financing and certain other
adjustments together with related tax effects:

In 1997, the Company completed its merger with Target in a tax-free,
stock-for-stock transaction accounted for as a pooling-of-interests. In
conjunction with this merger, Target's stockholders received 1.07 shares of the
Company's common stock in exchange for each share of Target common stock.
Approximately 33 million shares of the Company's common stock were issued in
connection with the Target merger.

In 1996, the Company completed its merger with EPT in a stock-for-stock
transaction. The transaction, which is accounted for as a pooling-of-interests,
was effected through the exchange of 0.297 shares of the Company's common stock
for each EPT share held. Approximately 6.8 million shares of the Company's
common stock were issued in conjunction with the EPT merger.

In 1996, the Company acquired Symbiosis, formerly a wholly-owned subsidiary of
American Home Products Corporation, for approximately $153 million in a cash
transaction. The acquisition was accounted for using the purchase method of
accounting.

In 1996, the Company purchased the assets of Endotech/MinTec for approximately
$72 million in a cash transaction accounted for using the purchase method of
accounting.


NOTE M - RESTRUCTURING AND
MERGER-RELATED CHARGES

The Company is in the process of implementing a rationalization plan established
after acquiring Schneider. The rationalization plan takes into consideration
duplicate capacity and opportunities for further leveraging of cost and
technology platforms. The Company's actions approved and committed to in the
fourth quarter of 1998 will result in the displacement in 1999 of approximately
2,000 current positions, over half of which are manufacturing positions. The
Company has decided to close five Schneider facilities, as well as transition
the manufacturing of selected Boston Scientific product lines to different
sites. The Company estimates that the costs associated with these activities
will be approximately $62 million, most of which represent severance and related
costs. Approximately $36 million of the total has been capitalized as part of
the purchase price of Schneider. The remaining $26 million ($17 million, net of
tax) has been charged to operations. The rationalization plan also resulted in
the decision to expand, not close, a facility originally provided for in a 1997
merger-related charge; thus, in the fourth quarter, the Company reversed $21
million ($14 million, net of tax) of previously recorded merger-related charges.
The reversal also includes estimated reductions in contractual commitment
payments, associated legal costs and other asset write-downs originally provided
for as a 1997 merger charge. In the second quarter of 1998, the Company
reorganized certain U.S. sales organizations differently than was originally
contemplated at the time of the Target acquisition. As a result, the Company
reversed $20 million ($13 million, net of tax) of 1997 merger-related charges.

At December 31, 1998, the Company had an accrual for restructuring and
merger-related charges of $89 million, which is comprised of $50 million of
accrued severance and related costs associated with integrating Schneider and
streamlining manufacturing operations, $16 million related to the cost of
cancelling contractual commitments recorded in connection

with the Schneider acquisition and $23 million of accruals remaining for 1997
and prior mergers (primarily costs associated with rationalized facilities).

During 1997, the Company recorded merger-related charges of $146 million ($106
million, net of tax) primarily related to the Company's acquisition of Target.
At December 31, 1995, the Company's accrual for restructuring and merger-related
charges was $136 million. During 1996, the Company recorded merger-related
charges of $32 million ($29 million, net of tax) related primarily to the
Company's acquisition of EPT. Charges utilized in 1996 were approximately $102
million.

The restructuring and merger-related charges were determined based on formal
plans approved by the Company's management using the best information available
to it at the time. The amounts the Company may ultimately incur may change as
the balance of the Company's initiative to integrate the businesses related to
these mergers and acquisitions is executed.

during 1998 and 1997, net of reclassifications made by management based on
available information, is summarized in the table below:

Boston Scientific is a worldwide developer, manufacturer and marketer of medical
devices for less invasive procedures. The Company has four reportable operating
segments based on geographic regions: the United States, Europe, Japan and
Emerging Markets. Each of the Company's reportable segments generates revenues
from the sale of minimally invasive medical devices. The reportable segments
represent an aggregate of operating divisions.

Sales and operating results of reportable segments are based on internally
derived standard foreign exchange rates and do not include inter-segment
profits. Because of the interdependence of the reportable segments, the
operating profit as presented may not be representative of the geographic
distribution that would occur if the segments were not interdependent. Total
assets and purchases of property, plant and equipment are based on foreign
exchange rates used in the Company's consolidated financial statements.

REPORT OF INDEPENDENT AUDITORS
- --------------------

BOARD OF DIRECTORS
BOSTON SCIENTIFIC CORPORATION

We have audited the accompanying consolidated balance sheets of Boston
Scientific Corporation and subsidiaries as of December 31, 1998 and 1997, and
the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period ended December 31, 1998.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Boston Scientific
Corporation and subsidiaries at December 31, 1998 and 1997, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles.

As more fully described in Note A, in 1997, the Company changed its accounting
policy to conform to the consensus reached by the FASB Emerging Issues Task
Force on its Issue No. 97-13.

During the fourth quarter of 1998, the Company recorded a charge of $26 million
representing estimated severance and other related cost associated with
integrating Schneider and streamlining manufacturing operations and reversed $21
million of merger-related amounts no longer required. Fourth quarter results
also include adjustments of $30 million related primarily to write-downs of
assets no longer deemed to be strategic. During the third quarter of 1998, the
Company recorded a $671 million charge to account for purchased research and
development acquired in the purchase of Schneider. Further, the third quarter
results include a provision of $31 million for costs associated with the
Company's decision to voluntarily recall the NIR ON(TM) Ranger(TM) with Sox(TM)
coronary stent system in the U.S. During the second quarter of 1998, the Company
reversed approximately $20 million of merger-related amounts no longer required
and recorded purchased research and development of $11 million in connection
with another acquisition consummated during the period.

The Company recorded merger-related charges and purchased research and
development totaling $158 million and $17 million during the second and fourth
quarters of 1997, respectively. In addition, during the fourth quarter of 1997,
the Company recorded provisions for inventory write-downs ($19 million),
litigation-related reserves ($34 million) and implemented EITF No. 97-13,
"Accounting for Costs Incurred in Connection with a Consulting Contract or an
Internal Project that Combines Business Process Reengineering and Information
Technology Transformation", the effect of which ($31 million) is reflected as a
cumulative effect of change in accounting.

On November 3, 1998, the Company announced it had detected the occurrence of
business irregularities in the operations of its Japanese subsidiary. As a
result, the Company has restated its quarterly results for the first three
quarters of 1998 which allows for more accurate period to period comparisons.
The restatement resulted in a decrease in revenues of $34 million for the six
months ended June 30, 1998. Revenues, as previously reported, were $470 million
and $506 million for the quarters ended March 31, 1998, and June 30, 1998,
respectively. Net income (loss), previously reported, was $67 million, $79
million, and $(509) million for the quarters ended March 31, 1998, June 30,
1998, and September 30, 1998, respectively.

The Company paid a two-for-one stock split on November 30, 1998. All historical
amounts above have been restated to reflect the stock split.

The Company has not paid a cash dividend during the past five years. The Company
currently intends to retain all of its earnings to finance the continued growth
of its business. Boston Scientific may consider declaring and paying a dividend
in the future; however, there can be no assurance that it will do so.

At December 31, 1998, there were approximately 8,600 record holders of the
Company's common stock.
