BOSTON SCIENTIFIC - AN INTEGRATED, GLOBAL HEALTHCARE ENTERPRISE


Over the last three years, Boston Scientific focused intensely on creating and
rapidly building Strategic Mass. A concept introduced in our 1995 Annual Report,
Strategic Mass means selectively assembling the components required for future
success and leadership in our chosen business segments. Through a concerted
program of mergers and acquisitions, we have significantly broadened the
capabilities we offer our physician customers and the patients they treat around
the world. As we have added new companies, integrated new businesses, developed
new technologies and expanded into new geographies, we have literally
transformed ourselves into a new Boston Scientific - an integrated, global
healthcare enterprise.

Historically, our customers have come to know us as one of our individual
business units, while to our shareholders and the financial community, we were
Boston Scientific. Our new corporate identity better describes who we are to all
constituents by expressing the broader value of our combined organizations: a
sense of unity, of shared commitment, and of global leadership as a focused,
dynamic force in the field of less invasive medicine.

With our new identity, we present Boston Scientific to the world as a single
entity while continuing to build upon the powerful equity we have in our
business unit names. By unifying and strengthening the relationship between each
unit and the corporation, the new identity will underscore the clinical and
economic value of Boston Scientific as a global healthcare enterprise with an
unmatched team of professionals across a wide range of disciplines and
specialties.

Our new corporate identity is much more than simply a new look. It is an ongoing
reflection of our values, and it communicates how we will succeed as we go
forward - as a single, integrated enterprise effectively leveraging the
individual strengths of our business units, our geographies and our people on a
worldwide basis.

Chairman's LETTER


Reflecting back on 1997, I am pleased to report that last year was another
extraordinary one for your company. We once again achieved record revenues,
maintained superior sales growth and momentum worldwide, and launched more new
products than ever before. We successfully integrated the Target team into our
worldwide organization. We welcomed many other new teammates to Boston
Scientific and established new area organizations in Asia Pacific and Latin
America. We implemented our new global information systems on schedule and
almost to completion, making enterprise-wide business planning a worldwide
reality in 1998 and thereby creating new opportunities for increased efficiency
and profitability. We initiated a new corporate identity program in order to
clarify and strengthen the image of our company so as to enable our customers to
better understand who we are and what we do. We continued the process of
consolidating and restructuring our operations worldwide by closing
manufacturing facilities in Denmark, France and Massachusetts while expanding
and strengthening our identified Centers of Excellence in Massachusetts,
Minnesota, Indiana, California, Florida, Washington, Ireland and Japan. We also
formalized long-term partnership agreements with a number of our group buying
customers in the United States, furthering our commitment to become an even more
valued partner to both large and small healthcare provider groups worldwide.

While we were busy discovering new and better ways to serve our customers and
further extend our leadership, we also became more appreciative of our
vulnerabilities. For example, a critical element of our goal to rapidly achieve
Strategic Mass included a massive investment over the past three years to
enlarge our presence in global markets outside of North America. While we have
enjoyed significant growth in this connection and have established ourselves as
the number one global enterprise in several of our industry segments, in 1997,
Asian and European currency markets worked against us and significantly reduced
the value of our operational successes. Further, significant and unexpected
reductions in reimbursement prices in France and Germany plus unwarranted delays
in product approvals and reimbursement coverage, principally in Japan,
collectively cost the company in excess of $200 million in planned revenue, much
of which fell directly to earnings. These phenomena are, of course, external and
for the most part beyond our control, and external events can have either
positive or negative effects during any given period. In 1997, the effect was
clearly negative and reduced business and financial flexibility. This also
magnified the challenges presented to our maturing organization by our own
highly ambitious plans.

While the Strategic Mass that we have achieved, which we now call the New Boston
Scientific, continues to create the potential for enormous competitive advantage
and great promise for strengthening our leadership position throughout the
world, we recognize, more clearly than ever, the work yet required to realize
fully the benefits of the New Boston Scientific.

We operated throughout most of 1997 utilizing legacy information systems we
inherited with our many acquisitions. These were cobbled together for the short
term while we invested aggressively in a global systems project to supersede
them. The conversion to the new systems, now largely complete, has occurred with
remarkable speed and success. Our interim reliance on the older systems,
however, dramatically confirmed the urgent need to replace them. They simply
could not provide the kind of timely and accurate information needed to
knowledgeably manage our business, and our execution suffered. Throughout the
year, increases in working capital reduced our cash; visibility on manufacturing
costs was less than optimal; new product planning and execution were below our
goals; and inaccurate forecasting created a cascade of new challenges
throughout the worldwide operation that we had not previously experienced. While
we believe these effects are now largely behind us, they were unprecedented in
both occurrence and impact. As a result, our fundamental financial business
model was compromised in 1997. Period charges reduced gross margins, and lost
revenue opportunities and the cost of debt further reduced profitability.

Even as our business discipline and our business fundamentals were compromised
in 1997 by both external factors and internal issues, we were already
establishing plans and programs designed to restore this aspect of our business
to our historic standards. Every member of the Boston Scientific Team now better
understands how his or her role relates to this objective, and we are committed
to achieving rapid success.

While we are committed to demonstrate superior business practices and
accomplishments across all areas of business performance, we must not lose sight
of the underlying operational success we have experienced with our customers
and the market place in general. In 1997, our market shares again increased in
every market in which we competed worldwide and our unit growth was up
substantially, indicating that we improved more patients' lives than our sales
numbers suggest. Absent pricing reductions worldwide and exchange rate losses,
which understate and therefore misrepresent the impact we have on our customers,
our business model in 1997 would have looked quite different. If we had met our
own expectations and standards for execution, our business model would have
looked even better.

Mindful of this and now more appreciative of what we can and must do to restore
strong business fundamentals throughout the organization, we have established
clear goals and processes for ourselves in 1998.

     SYSTEMS
     As our investment in enterprise-wide systems winds down and this new
     technology becomes an everyday way of life at Boston Scientific, we expect
     to see significant improvements in process, planning and control. Not only
     will formal planning and performance analysis become friendlier and more
     timely, the full range of activities which affect the supply chain will
     improve dramatically. We now have the opportunity to gain visibility
     worldwide on working capital, requirements planning and logistics. These
     are all areas where we struggled in 1997 as a result of the geographically
     far-flung nature of our operations and the growing size and complexity of
     our business.

     GLOBALIZATION
     As the new millennium approaches, we foresee more than half of our revenue
     and activities based on commerce outside of the United States. We are
     actively becoming a truly global enterprise. For Boston Scientific, this
     means thinking transnationally about business organization and new product
     opportunities; about

increased collaborations with worldwide customers; about priorities based on
being first to market globally with innovation; and about governance and
management. It means benchmarking our own behavior and standards against
world-class best practices regardless of source, and having the courage to
measure ourselves against them.

THE TEAM

At the end of the day, it is the quality and competence of Boston Scientific
people that makes the real difference.

Each year, we develop our plan very carefully with the
worldwide organization. Our objectives are to insure
that everyone understands the overall plan, understands
their own role and contribution to the plan, possesses
the competency to perform successfully, and not only
believes in the plan and their own ability to            [Boston Scientific

simplified and clarified year-end performance-based
incentive programs to better align behavior and more
clearly focus the Team's attention on the most crucial
success factors.

We have also added more management depth and experience to
the Team. In particular, I would like to welcome two new
Boston Scientific executives. During the last quarter of
1997, Michel Darnaud joined us as President of Boston
Scientific Europe and Philip Le Goff was appointed Senior
Vice President and Group President of Boston Scientific
worldwide Vascular Businesses. Both Michel and Phil bring
great talent and leadership skills from successful
transnational experiences in the healthcare industry, and we
are fortunate to have attracted them to our company.

These senior management additions, as well as other
initiatives, are clearly aimed at broadening and
strengthening our Team. On-the-job training and business as
usual in and of itself may yield dividends in overall
organization efficiency and effectiveness, but this is not
enough. We must assure ourselves that we employ and retain
the very best people available throughout the organization
and that all are highly motivated. They must share together
a real sense of urgency and enthusiasm for what they do and
that what they do is characterized by speed, absolute
quality and unqualified success. Our goal is to strengthen
our organization and continuously improve individual and
Team effectiveness worldwide with processes which become
ingrained as a way of life at BSC.

     SUBSEQUENT EVENTS
     1998 has certainly become the year of the stent in the medical device
     industry. This class of device has overnight become the single largest
     selling product in the history of our young industry. I am pleased to
     report that during the months of December and January, we filed our
     long-awaited PMA's with the U.S. Food & Drug Administration for the
     Radius(TM) and NIR(TM) stent platforms. Boston Scientific has achieved
     stent leadership outside of North America, and we expect to match that
     performance in North America when these important new devices are approved
     and made available to physicians and their patients in the United States.
     Our comprehensive stent portfolio is discussed in detail later in this
     report.

In closing, I would be remiss if I did not note that the healthcare industry in
the United States, and indeed worldwide, continues to experience dramatic
transformation and realignment. Within our segment of this system, consolidation
will continue at a brisk pace as the forces of cost, scale, efficiency, outcomes
and the demands of strategic focus continue to redefine the conventional wisdom
of our business.

Through this change, the mission of Boston Scientific, as shown on the next
page, remains clear. As we look back over our brief history as a company, "Our
Fantastic Voyage," we can now see more clearly our own transition from a small,
private startup company seeking to find its way (1979-1992); to a newly minted
public company with aspirations for leadership, finally with the currency to do
something about it (1992-1994); to a leader/consolidator/builder of Strategic
Mass in order to achieve better alignment with the new world of economic buyers
and national group purchasing organizations (1994-1997); to where we are today
poised on the threshold of the execution era. This change that surrounds us we
take as an opportunity and an advantage.

The Boston Scientific Team is solid, intact, and learning every day to move
faster and more efficiently, taking risks, stretching and extending itself on
behalf of its customers. We are guided by a set of proven values and Team
conviction that every product, every procedure, every technology, every device
we develop and sell provides the opportunity for a physician somewhere in the
world to reach out to sick patients and make them better. Boston Scientific is
an exhilarating company building for the future. Those who believe in our vision
for the future and share that belief with the BSC Team will be rewarded.

Thank you Boston Scientific Teammates, shareholders, customers and friends for
sharing our vision. Together our shared beliefs, commitments, loyalty and
unselfishness make our vision a reality.

Mission-driven, global resources focused on local needs everywhere. This is 
much more than the theme of our 1997 annual report. It is a behavior that we 
have adopted at Boston Scientific and one that we believe will enable continued
leadership in less invasive medicine. Our ongoing challenge is effectively and
efficiently harnessing global resources to improve patient outcomes and lower
treatment costs in ways that are meaningful in local markets. How we apply our
global strengths in product development, customer education, distribution and 
the application of less invasive technologies with the responsiveness of a local
company is described on the following pages.


BOSTON SCIENTIFIC CORPORATION
MISSION STATEMENT

Since its origin in the late 1960s, Boston Scientific Corporation's mission
has been to improve the quality of patient care and the productivity of 
healthcare delivery through the development and advocacy of less invasive 
medical devices and procedures. This is accomplished through the continuing 
refinement of existing products and procedures and the investigation and 
development of new technologies which can reduce risk, trauma, cost, procedure
time, and the need for aftercare.

                              offer an intensive, hands-on environment in which
                              physicians and training specialists can share
                              skills, knowledge and experience directly with one

                              the connection with our physician customers that
                              will enable us to solve unique Japanese problems
                              and develop outcomes-oriented technologies that
                              reduce healthcare costs in an iterative and open
                              fashion.

                              Our efforts in Japan do more than meet local
                              needs. They demonstrate how we capitalize on the
                              unique global strength of Boston Scientific - by
                              thinking and acting as a Japanese-based
                              organization with access to global resources and
                              by applying what we learn from our customers in

We are energized by the opportunity to provide more effective and affordable
healthcare treatments to physicians and their patients in less developed
countries. These regions, which include some of the largest and fastest-growing
populations in the world, have had few alternatives to highly invasive
procedures, sometimes performed under less than ideal conditions.

We have a unique opportunity to make a significant, positive difference in the
quality of life for thousands of people in markets such as Latin America, the
Middle East, China and Southeast Asia. We have opted to pursue a sales model
that places local Boston Scientific employees throughout the world and enables
us to more closely collaborate with our physician customers to develop
technologies and to realize optimal product utilization and economic value for
their needs. In addition, we are better able to access unique physician talents
in these markets and apply their insights globally. For example, we travel to
Buenos Aires, Argentina to work with Dr. Juan Parodi, a recognized leader and
pioneer in endovascular surgery, as part of our global development process.

As we grow the sales organization, our focus is first on providing advanced
sales and product training to every member of the team. We began the new year by
bringing together sales representatives from more than 20 countries to learn
side by side with their peers during an intensive training seminar. More
experienced colleagues from different areas of the world led many of the
sessions, conducted in nine languages, and shared their knowledge and insight.
When it was over, 300 professional, highly trained, enthusiastic sales
representatives returned to their home countries equipped to demonstrate the
value of less invasive technology solutions to local physicians and well
connected to their colleagues and the Boston Scientific knowledge base for
continuous learning.
 
Our ongoing supply chain integration initiatives and systems have made it
not only possible, but also practical for us to reach customers throughout this
part of the world quickly and efficiently. The opening of our Singapore facility
in early 1997 has enhanced this effort by creating a third global hub in the
Boston Scientific distribution network. Our global systems project will further
strengthen our ability to aggressively manage worldwide product inventory and
logistics through our Far East, South American, North American, European and
Japanese facilities. No matter where a product is sourced or how it travels
through the system, the goal is the same -- a seamless process that enables us 
to get the product into the physician's hands overnight.

Leadership in Emerging Markets will be achieved and maintained if we follow a
few simple tenets of the Boston Scientific philosophy: customer intimacy is the
core; more effective and affordable healthcare is the outcome; direct, two-way,
face-to-face communication with local physicians is the method; and patients
around the world benefiting from less invasive solutions is the ultimate goal.

[We are extremely proud of the accomplishments of our research and development
teams. As shown here, their efforts play a key role in building and 
strengthening our intellectual property.]



The economic and social pressures which erupted in 1997 throughout Europe have
dramatically increased the economic influence on healthcare purchasing de-
cisions virtually overnight. While the magnitude of this change is a significant
challenge for all participants in the medical device market, we see it
ultimately as a long-term opportunity for Boston Scientific.

We fundamentally believe that our focus on less invasive treatments and the
breadth of our Strategic Mass enables us to deliver better patient outcomes at a
lower total cost to society. In the past, proving clinical benefit was enough to
succeed, but the new economic environment across Europe requires similar rigor
in demonstrating that patients treated with our products require a lower total
cost of treatment for equivalent or better outcomes.

We are capturing data and building health economics modeling capabilities to
bring the right clinical and economic information to the new decision makers in
Europe and around the world: physicians, hospital purchasers, insurance
companies and governments. We are expanding our ability to precisely measure,
model and communicate the full economic benefits for each technology, and
because medical practices and reimbursement systems vary by country even within
Europe, we are taking a local approach where appropriate.

In response to changing customer needs, we are entering a new era of European
customer service and distribution capability. The investments we have made in
systems will begin paying off in 1998. Before mid-year, our central European
warehouse in The Netherlands will be linked real time electronically not only
with our international manufacturing center in Galway, Ireland, but with all of
our plants and distribution centers around the world. We will spend less time,
effort and money handling products while getting them to customers faster.

Incorporating manufacturing and development closer to the customer continues to
be an important theme for Boston Scientific. In the gastrointestinal cancer
arena, we are beginning to experience the benefits of close collaboration with
European GI endoscopists as colonic stents, being developed and manufactured in
Ireland, enter clinical trials in early 1998.

Continued growth in international markets and the outstanding performance of our
Galway workforce have led us to pursue a second Irish facility in Cork.
Initially, this facility will be a small international manufacturing center for
neuroradiology products developed by Boston Scientific's Target business unit,
today our third largest business in Europe. Ultimately, it will provide
additional capacity to serve growth markets.

Lasting growth and leadership in a Europe preparing for and then adapting to

Boston Scientific's Marina Bay Customer Fulfillment Center opened in May of
1997. Located in Quincy, Massachusetts, U.S.A., the 1.3 million-square-foot
facility is equipped with state-of-the-art distribution equipment, including our
global information systems. By integrating inventory from all plants into one
central location, we expect to realize increased U.S. distribution efficiencies
of 17-20%.


Boston Scientific's ability to leverage global expertise to develop new
treatment solutions is well illustrated through our carotid stent technology
program being developed for multiple Boston Scientific specialty markets. The
team consists of employees from various functional areas across Boston
Scientific business units.

                                                                         [PHOTO]

OPTIMIZING STENT SOLUTIONS

Throughout the body are many types of tubes and vessels
which can become blocked or can malfunction due to disease
or injury. Stents are an important tool our physician              [HUMAN BODY
customers use for long- term, less invasive treatment of            SKELETON]
these problems. Figure 1 shows where Boston Scientific stent
technology is currently being applied as well as areas under
development.                                                        Figure 1

We apply the same principles of Strategic Mass to our stent
technology that we do across our entire business - product
line breadth and technology leverage to effectively provide
the right tool for the job. Because the variety of places
and problems which are treated with stents require unique
solutions, we have developed multiple technology platforms
and leveraged those platforms to where they provide the most
useful treatment (see Figure 2).

The next step in optimal stent solutions is to provide
adjunctive technologies which help stents perform better and
can also be therapies themselves. We are researching the use
of antiproliferative agents such as paclitaxel, genes and
other pharmacologically active compounds delivered in
coatings on stents or by special balloons to address vessel
restenosis and further increase long-term patient benefit.

- --------------------------------------------------------------------------------
Figure 2  The clinical applications for stenting are many and varied. We are
          actively working to extend our multiplatform stent and delivery system
          capabilities to provide our customers with optimal stent solutions
          that are as unique and diverse as the diseased arteries, lumens and
          vessels they treat.

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

RESULTS OF OPERATIONS

During the past three years, Boston Scientific Corporation (Boston Scientific or
the Company) has consummated numerous mergers and acquisitions that are
expected to improve the strategic position of the Company to take advantage of
additional significant growth opportunities in less invasive medicine. In 1995,
the Company merged with or acquired SCIMED Life Systems, Inc. (SCIMED),
Cardiovascular Imaging Systems, Inc. (CVIS), Vesica Medical, Inc. (Vesica),
Meadox Medicals, Inc. (Meadox) and Heart Technology, Inc. (Heart). In 1996, the
Company merged with or acquired EP Technologies, Inc. (EPT), Symbiosis
Corporation (Symbiosis) and Endotech Ltd. and MinTec Inc., and certain related
companies (Endotech/MinTec).

On April 8, 1997, the Company completed its merger with Target Therapeutics,
Inc. (Target) in a tax-free, stock-for-stock transaction accounted for as a
pooling-of-interests. Target designs, develops, manufactures and markets
catheter-based disposable and implantable medical devices used in minimally
invasive procedures to treat neurovascular diseases and disorders. In
conjunction with this merger, Target's stockholders received 1.07 shares of
Boston Scientific common stock in exchange for each share of Target common
stock. Approximately 16.5 million shares of the Company's common stock were
issued in connection with the Target acquisition.

The Company has substantially completed the integration of all mergers and
acquisitions consummated in 1995 and 1996. The Company expects to complete the
integration of Target by the end of 1998. 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 changes 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.

The restated historical results of operations are not necessarily indicative of
the operating results or financial position that would have occurred if the
mergers and acquisitions had been consummated during the periods presented, nor
are they necessarily indicative of future operating results or financial
position. 

YEARS ENDED DECEMBER 31, 1997 AND 1996

Net sales increased 21% in 1997 to $1,872 million from $1,551 million in 1996.
International net 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 26%. Net income for the
year ended December 31, 1997, excluding merger-related and special charges,
increased 12% to $331 million from $295 million during the year ended December
31, 1996.

In 1997, the Company recorded merger-related expenses ($146 million) and
purchased research and development ($29 million), and the Company recorded
special charges related to inventory write-downs ($19 million),
litigation-related reserves ($34 million), and the impact of implementing a
recently issued accounting standard related to business process reengineering
($31 million). During 1996, the Company recorded merger-related expenses ($32
million) and purchased research and development ($110 million).

Reported net income for the year was $139 million, or $0.70 per share (diluted),
as compared to $167 million, or $0.84 per share, for the prior year.

United States (U.S.) revenues increased approximately 17% from 1996 to $1,076
million in 1997, while international revenues, including export sales,
increased approximately 27% from 1996 to $796 million in 1997. International
sales as a percentage of worldwide sales increased from 40% in 1996 to 43% in
1997. International sales during 1997 were negatively impacted compared to 1996
by approximately $82 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 19% and 27%, respectively, from 1996 to 1997.

Gross profit as a percentage of net sales was approximately 70.6% 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. Future
gross margins may be impacted by the Company's ability to effectively manage
its inventory level and mix. The Company is in the process of implementing a new
global information system that is expected to improve supply chain management.
The decrease in gross margin percentage is also partially due to 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.

Selling, general and administrative expenses increased 33% from $516 million in
1996 to $688 million in 1997, and increased as a percentage of sales from 33%
to 37% 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. The Company
believes the additional investments will enhance its competitive position in
the future.

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. 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.

During 1996 and 1997, the Company expanded its direct sales presence in Asia
Pacific and Latin America so as to be in a position to take advantage of
expanded market opportunities. The costs of expansion have negatively impacted
the Company's operating margins. The Company's ability to benefit from its
expansion may be limited by risks and uncertainties related to economic
conditions in these regions, in addition to competitive offerings,
infrastructure development, rights to intellectual property, and the ability of
the Company to implement its overall business strategy. 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. The Company believes that it will be able to realize improved long-term
returns on its investments with a direct selling presence in these regions.

The Company's 1997 operating expenses increased at a faster percentage than net
sales and the Company expects this relationship to continue during the first
half of 1998. However, the Company also expects that the additional investments
in infrastructure will enhance its competitive position in the second half of
1998 and beyond.

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 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
reimbursement levels and healthcare costs. Although these factors will continue
to 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.

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 was approximately 45% in 1996 and 38% in 1997.
The effective tax rates for 1996 and 1997 include the impact of special charges.
Excluding these items, the pro forma effective tax rate improved from
approximately 34% during 1996 to 32% during 1997. The reduction

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

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.

In 1997, the Company recorded a $31 million ($21 million, net-of-tax) cumulative
effect of change in accounting from implementing Emerging Issues Task Force 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 Company does not expect future costs
for the business process reengineering component of its global information
systems project to be material. 

YEARS ENDED DECEMBER 31, 1996 AND 1995

Net sales increased 30% in 1996 to $1,551 million from $1,191 million in 1995.
Net income for the year increased to $167 million, or $0.84 per share (diluted),
as compared to a loss of $18 million, or $0.10 per share, in the prior year. Net
income for the year ended December 31, 1996, excluding special charges related
to 1996 and 1995 acquisitions, increased 39% to $295 million from $212 million
during the year ended December 31, 1995.

U.S. revenues increased approximately 20% from 1995 to $924 million in 1996,
while international revenues, including export sales, increased approximately
50% from 1995 to $627 million in 1996, or 57% excluding the negative impact of
exchange rate movements. International sales as a percentage of worldwide sales
increased from 35% in 1995 to 40% in 1996. Worldwide vascular sales increased
29% from 1995 to 1996 and worldwide nonvascular sales during the same periods
increased 26%.

During 1996, the Company accelerated its forward build and spend programs so as
to be in a position to take advantage of the expanded market opportunities. The
programs impacted the Company's manufacturing and selling, general and
administrative costs.

Gross profit as a percentage of net sales was approximately 72.4% and 71.2%
during 1996 and 1995, respectively. During 1996, the Company's gross margins
improved as a result of the Company's U.S. cost containment programs, an
increase in the percentage of international sales compared to U.S. sales, and
certain benefits of converting from selling through international distributors
to direct sales operations. However, the positive impact of these initiatives
was offset by the forward spend programs discussed previously, a slight decline
in average selling prices due to continuing pressure on healthcare costs and
increased competition, and a shift in the Company's product sales mix. In
addition, gross margins were negatively impacted by the unfavorable foreign
exchange rate movements discussed above.

Selling, general and administrative expenses increased 32% from $392 million in
1995 to $516 million in 1996, and remained approximately 33% of net sales. The
increase reflects continued expansion of the Company's domestic and
international sales organizations and related marketing support.

Royalty expenses decreased 35% from $26 million in 1995 to $17 million in 1996
and decreased from approximately 2% of net sales to 1% of net sales. The
decrease is primarily attributable to a reduction in sales of certain of the
Company's PTCA products that are subject to royalties. However, the reduction
was partially offset by royalties due under several strategic alliances that
the Company initiated in 1996 and prior years.

Research and development expenses increased 28% from $106 million in 1995 to
$135 million in 1996 and remained approximately 9% of net sales. The increase
in 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 $6 million in 1996 as compared to $16 million
in 1995. 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
finance several of the Company's strategic alliances and infrastructure build
during the second half of 1995 and throughout 1996. Interest expense increased
from $10 million in 1995 to $12 million in 1996. The increase in interest
expense is primarily attributable to interest on borrowings used principally to
finance the acquisitions of Symbiosis and Endotech/MinTec and the Company's
stock repurchase program. Other income (expense), net, changed from income of
$4 million in 1995 to expense of $5 million in 1996. The change is primarily
attributable to net foreign exchange losses recorded in 1996 of $2 million
compared to net gains of $8 million recorded in 1995.

The Company's effective tax rate was approximately 129% in 1995 and 45% in 1996.
The effective tax rates for 1995 and 1996 include the impact of special charges
(see discussion following). Excluding these items, the pro forma effective tax
rate improved from approximately 37% during 1995 to 34% during 1996. During
1995, the Company reorganized its international legal structure, which has
contributed to a reduction in the effective tax rate. 

LIQUIDITY AND CAPITAL RESOURCES

During 1997, the Company continued to invest in several strategic initiatives
and infrastructure in order to take advantage of certain growth opportunities
that exist in less invasive medicine. Cash, cash equivalents, and short-term
investments totaled approximately $80 million as of December 31, 1997 compared
to $118 million as of December 31, 1996. Working capital was reduced from $335
million at December 31, 1996 to $256 million at December 31, 1997, and cash
provided by operating activities decreased from $142 million during 1996 to $80
million during 1997. The decrease in cash and marketable securities is primarily
attributable to cash used to repurchase the Company's common stock, capital
expenditures incurred to expand the Company's manufacturing and distribution
facilities, additional strategic initiatives and payment of merger-related
costs. The cash expenditures were par- 


                                      F-4
                 BOSTON SCIENTIFIC CORPORATION AND SUBSIDIARIES
   21
tially offset by proceeds from operating activities and additional borrowings
under the Company's financing arrangements.

During 1997, accounts receivable increased $93 million as a result of the
Company's sales growth and the transition to selling directly to international
customers. Days sales outstanding has increased from 68 days in 1996 to 77 days
in 1997 primarily as a result of the growth in international sales. The
Company's bad debt provision may be impacted by its ability to effectively
collect receivables due from its international distributors. Inventory increased
$150 million during 1997 primarily as a result of stocking the NIR(TM) stent in
preparation of the Company's planned 1998 launch in the U.S. and Japan. The
remaining increase is a result of inefficiencies in the global supply chain. The
Company is committed to purchase approximately $75 million of NIR stents during
1998. The Company expects inventory levels to peak in mid-1998 and then begin to
decline as the NIR stent is launched in the U.S. and Japan, and as the Company's
new global supply chain becomes fully operational. Successful implementation of
the Company's supply chain initiatives is necessary to reduce the Company's
inventory to an acceptable level. Although no significant issues have arisen in
the past, there can be no assurance that current or future suppliers of the
Company's raw materials will be able to continue to meet the quality and
quantity demands of the Company at current suppliers' prices.

Cash used for investing activities for 1997 was $251 million and was primarily
related to property, plant and equipment costs associated with the Company's
expansion of manufacturing and distribution capacity.

During 1997, net cash provided by financing activities was approximately $162
million and consisted primarily of proceeds from issuance of commercial paper
and long-term borrowings and the exercise of stock options partially offset by
the acquisition of treasury stock.

In connection with its 1995 and 1996 mergers and acquisitions and the Company's
initial investment in Medinol, Ltd. (Medinol), the Company recorded
merger-related charges of approximately $272 million ($231 million, net-of-tax)
and $142 million ($128 million, net-of-tax), respectively. In addition, during
1997, the Company recorded special charges in connection with its acquisitions
of approximately $175 million ($135 million, net-of-tax). Estimated costs
include purchased research and development ($29 million) and those costs typical
in a merging of operations and relate to, among other things, rationalization of
facilities, workforce reductions, unwinding of various contractual commitments,
asset write-downs and other integration costs. The Company does not expect costs
incurred to complete purchased research and development projects to be
material. During 1997, cash payments related to these charges were
approximately $105 million and estimated cash payments for 1998 are $51 million.

The Company is authorized to purchase on the open market up to approximately 20
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 the
Company's obligations pursuant to its employee benefit and incentive plans.
During 1997, the Company repurchased 3.5 million shares of its common stock at
an aggregate cost of $188 million. Prior to 1997, 6.5 million shares of the
Company's common stock were repurchased under the program.

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 focusing on strategic initiatives and/or make
additional investments in existing relationships. In addition, the Company
expects to incur capital expenditures of approximately $230 million in 1998,
including completion of construction of additional manufacturing space and
completion of its global information system. The Company's new global
information system is Year 2000 compliant. The Company is assessing other
programs and products to determine if they are Year 2000 compliant and the
Company does not anticipate that additional compliance costs will have a
material impact on its business, operations or its financial condition.

In October 1997, the Company filed a Public Debt Registration Statement with
the U.S. Securities and Exchange Commission. Under the Registration Statement,
the Company may issue up to $500 million in debt securities in the public
market. In February 1998, the Company made an additional filing necessary to
issue $500 million of debt securities under the Registration Statement. The
Company expects the issuance to move forward and to receive the proceeds of the
issuance during March 1998. A significant portion of the net proceeds from the
sale of the securities will be used for repayment of indebtedness under the
Company's commercial paper program, and the remainder of the net proceeds of
this offering will be used principally to fund general corporate purposes. The
Company may borrow additional amounts under its revolving credit agreement in
the future, and the Company plans to increase its Japanese borrowing facilities
used primarily to discount its accounts receivable. The Company expects that
its cash and cash equivalents, marketable securities, cash flows from operating
activities, proceeds from the issuance of the debt securities noted above and
borrowing capacity will be sufficient to meet its projected operating cash
needs, including integration costs at least through the end of 1998. The Company
may need to increase its bank facilities during 1998 if it continues to execute
strategic initiatives, although there are no assurances that additional
financing can be or will be obtained. 

MARKET RISK DISCLOSURES

The Company's floating and fixed rate debt obligations are subject to interest
rate risk. If interest rates increase 100 basis points in 1998, the increase
would not result in a material change in the Company's interest expense or the
fair value of the Company's debt obligations. A 100 basis point increase would
not result in a material increase in interest income or the fair value of the
Company's short-term investments.

The Company enters into forward 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

   22
MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Company's foreign exchange contracts, which amounted to approximately $177
million at December 31, 1997, 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.
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 market values at December 31, 1997. In addition,
unhedged foreign currency balance sheet exposures as of December 31, 1997 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. Thus, certain 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. 

LITIGATION

The Company is involved in various lawsuits, including 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 the 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. During 1997, the Company recorded
approximately $34 million of litigation-related reserves to cover costs of
defense and settlement, and unfavorable outcomes. The reserves are included in
selling, general and administrative expenses.

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.

CAUTIONARY STATEMENT FOR PURPOSES OF THE
SAFE HARBOR PROVISIONS OF THE PRIVATE SECURITIES
LITIGATION REFORM ACT OF 1995

This report contains forward-looking statements. The Company desires to take
advantage of the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995 and is including this statement for the express purpose of
availing itself of the protections of the safe harbor with respect to all
forward-looking statements. Forward-looking statements contained in this report
include, but are not limited to, statements with respect to: (a) the Company's
forward build and spend programs and its ability to benefit from investments in
expansion; (b) the Company's plans to continue to invest in its global systems
and worldwide manufacturing and distribution capacity; (c) the potential impacts
of continued consolidation among healthcare providers, trends towards managed
care, healthcare cost containment, more stringent regulatory requirements and
more vigorous enforcement activities; (d) the Company's belief that it is well
positioned to take advantage of opportunities for growth that exist in the
markets it serves; (e) 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; (f) the
research and development expenditures that will be incurred to complete
purchased research and development projects; (g) risks associated with
international operations; (h) the process and plan for the integration of
businesses acquired by the Company and the successful implementation of the
plan; (i) the potential effect of foreign currency fluctuations on revenues,
expenses and resulting margins and the trend toward increasing sales and
expenses denominated in foreign currencies; (j) the ability of the Company to
successfully manage accounts receivable and inventory levels and mix; (k) the
ability of the Company to meet its projected cash needs through the end of 1998;
(l) the Company's plans for launch of the NIR(TM) stent in the U.S. and Japan;
(m) the ability of global information systems to improve supply chain
management; (n) costs associated with implementing Year 2000 compliance and
business process reengineering; (o) the Company's belief that operating expenses
will increase at a faster percentage than net sales during the first half of
1998 and the expectation that the additional investments in infrastructure will
enhance the Company's competitive position in the second half of 1998 and
beyond; and (p) the ability of additional investments in sales and distribution
organizations to enhance the Company's future competitive position. 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, 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 to Note B)


NOTE A -- MERGERS AND ACQUISITIONS

On February 24, 1995, Boston Scientific Corporation (Boston Scientific or the
Company) completed its merger with SCIMED Life Systems, Inc. (SCIMED) in a
stock-for-stock transaction. The transaction, which is accounted for as a
pooling-of-interests, was effected through the exchange of 3.4152 shares of the
Company's common stock in exchange for each SCIMED share held. Approximately
52.7 million shares of common stock were issued in connection with the SCIMED
merger.

On March 9, 1995, the Company completed its merger with Cardiovascular Imaging
Systems, Inc. (CVIS), which is accounted for under the purchase method of
accounting. CVIS shareholders received $10.50 per share for an aggregate
purchase price of approximately $94 million (or approximately $82 million, net
of cash acquired, cash received and to be received from a third party under an
agreement, signed in conjunction with the acquisition, to license certain
intravascular ultrasound technology).

On March 23, 1995, the Company completed the acquisition of Vesica Medical, Inc.
(Vesica) which is accounted for under the purchase method of accounting. The
purchase price is not material to the Company's financial position or results of
operations and the acquisition did not have a material pro forma impact on the
Company's operations.

On November 16, 1995, the Company completed its merger with Meadox Medicals,
Inc. (Meadox). To effect the merger, Boston Scientific exchanged approximately
10.2 million shares of the Company's common stock for all the issued and
outstanding capital stock of Meadox on a fully-diluted basis in a
stock-for-stock, pooling-of-interests transaction.

On December 29, 1995, the Company completed its merger with Heart Technology,
Inc. (Heart) in a stock-for-stock transaction. The transaction, which is
accounted for as a pooling-of-interests, was effected through the exchange of
0.675 shares of the Company's common stock for each Heart share held.
Approximately 11.9 million shares of the Company's common stock were issued in
connection with the Heart merger.

On January 22, 1996, the Company completed its merger with EP Technologies, Inc.
(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 3.4 million
shares of the Company's common stock were issued in conjunction with the EPT
merger.

On March 14, 1996, the Company acquired Symbiosis Corporation (Symbiosis),
formerly a wholly-owned subsidiary of American Home Products Corporation. Boston
Scientific purchased Symbiosis for approximately $153 million in a cash
transaction. The acquisition was accounted for using the purchase method of
accounting.

On May 3, 1996, Boston Scientific acquired assets from Endotech, Ltd. and MinTec
Inc., and certain related companies (Endotech/MinTec). The Company purchased
Endotech/MinTec's assets for approximately $72 million in a cash transaction
accounted for using the purchase method of accounting.

On April 8, 1997, the Company completed its merger with Target Therapeutics,
Inc. (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 16.5 million shares of the Company's common
stock were issued in connection with the Target merger.


NOTE B -- SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include the
accounts of the Company and its subsidiaries, substantially all of which are
wholly-owned, and include the results of SCIMED, Meadox, Heart, EPT and Target
accounted for as poolings-of-interests, for all periods presented. The
statements also include the results of CVIS, beginning in March 1995, the
results of Symbiosis, beginning in March 1996 and the results of
Endotech/MinTec, beginning in May 1996. Investments in affiliates, representing
20% to 50% of the ownership of such companies, are accounted for under the
equity method. 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.

FISCAL YEAR: The Company has a fiscal year ending on December 31. In connection
with the SCIMED merger, effective January 1, 1995, SCIMED changed its fiscal
year end from the last day of February to December 31. As a result of the change
in SCIMED's fiscal year, the operations for the period January 1, 1995 through
February 28, 1995 have been included in the results of operations of Boston
Scientific both for the years ended December 31, 1995 and 1994. Summarized
results of SCIMED's operations for this two-month period are: Net sales: $55
million; Gross margin: $42 million; Operating income: $18 million; Net income:
$11 million.

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.

                 BOSTON SCIENTIFIC CORPORATION AND SUBSIDIARIES
   29
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 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 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 which, when
realized, have been within the range of management's expectations.

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

PROPERTY, PLANT, EQUIPMENT AND LEASEHOLDS: 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 7-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 during 1997 was $5 million. 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); Purchased technologies (3-20 years); Excess of cost over net
assets acquired (15-40 years); Other intangibles (Various).

The Company examines the carrying value of its goodwill and other long-lived
intangible assets to determine whether there are any impairment losses. If
indicators of impairment were present in long-lived intangible assets used in
operations, and future cash flows were not 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 impair the value of material
long-lived intangible assets recorded in the accompanying consolidated financial
statements.

INCOME TAXES: The Company utilizes the 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 and 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,
1997, unremitted earnings of non-U.S. subsidiaries were $311 million. When
these earnings are distributed in the form of dividends or otherwise, the
Company will be subject to both U.S. income taxes and foreign withholding taxes
less an adjustment for applicable foreign tax credits. 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.

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, which amounted to $177 million at
December 31, 1997 and which were immaterial at December 31, 1996, 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 1997 and 1996, net foreign
currency transaction and translation net gains (losses) that are reflected as
Other Income (Expense) on the Consolidated Statements of Operations totaled
approximately $4 million and $2 million, respectively, of net foreign exchange
losses compared to $8 million of net foreign exchange gains in 1995.

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.
Returned merchandise will be accepted only with written authorization from the
Company. Accruals are made and evaluated for adequacy on a monthly basis for all
returns.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Note B continued to Note E)


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 and Disclosure of Stock-Based Compensation".

ACCOUNTING CHANGE: The Company has 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 change in accounting.

NEW ACCOUNTING STANDARDS: The Company has not yet adopted SFAS No. 130,
"Reporting Comprehensive Income" and SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information" both of which will require adoption in
1998. The Company is in the process of determining the effect of adoption of
these statements on its consolidated financial statements and related
disclosures.

NET INCOME PER COMMON SHARE: In 1997, the Financial Accounting Standards Board
issued SFAS No. 128, "Earnings per Share". Statement 128 replaced the
calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share excludes any dilutive effects of options, warrants and convertible
securities. Diluted earnings per share is very similar to the Company's
previously reported primary earnings per share. All earnings per share amounts
for all periods presented have been restated to conform to the Statement 128
requirements.

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

NOTE E -- CREDIT ARRANGEMENTS

The Company's borrowings at December 31 consisted of:



(In thousands)                          1997          1996
- ----------------------------------------------------------

Long-term debt                        46,325


At December 31, 1997, the Company had a $500 million revolving line of credit
with a syndicate of U.S. and international banks (the Credit Agreement). Under
the Credit Agreement, the Company has the option to borrow amounts at various
interest rates, payable quarterly in arrears. The terms of the Credit Agreement
extend to 2002. Use of the borrowings is unrestricted and the borrowings are
unsecured. The Credit Agreement requires the Company to maintain a specific
ratio of consolidated funded debt (as defined) to consolidated tangible net
worth (as defined) plus consolidated funded debt. At December 31, 1997, the
Company had no outstanding borrowings under the Credit Agreement.

The Company maintains a commercial paper program that is supported by the
Company's Credit Agreement. Outstanding commercial paper reduces available
borrowings under the Credit Agreement. At December 31, 1997, the Company had
approximately $423 million in commercial paper outstanding with interest rates
ranging from 5.84% to 7.35%, compared to $213 million outstanding with interest
rates ranging from 5.55% to 6.03% at December 31, 1996.

In October 1997, the Company filed a Public Debt Registration Statement with the
U.S. Securities and Exchange Commission. During the first quarter of 1998, the
Company plans to issue up to $500 million in debt securities under this
Registration Statement. A significant portion of the proceeds from the public
offering will be used to repay the Company's borrowings under its commercial
paper program.

The Company has uncommitted credit facilities with several Japanese banks that
provide for borrowings and promissory notes discounting of up to 10.5 billion
yen, or approximately $81 million. At December 31, 1997 and 1996, borrowings

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Note E continued to Note H)

outstanding under these credit facilities were 2.7 billion yen (approximately
$21 million at December 31, 1997) and were borrowed at rates of approximately
1%. During 1997, approximately $194 million of receivables were discounted
through promissory notes compared to $130 million during 1996. At December 31,
1997, approximately $50 million of receivables were discounted at average
interest rates of approximately 1.6%; thus, the net availability under these
credit lines was $10 million.

During July 1997, the Company borrowed 6 billion yen (approximately $46 million
at December 31, 1997) under a fixed interest rate (2.22%) financing arrangement
with a syndicate of Japanese banks. The borrowings are payable in 2002.

Interest paid, including interest paid under capital leases and mortgage loans,
but excluding interest paid on a patent litigation judgment (in 1995), amounted
to $19 million in 1997, $13 million in 1996, and $6 million in 1995.


NOTE F -- LEASES

Rent expense amounted to $37 million in 1997, $22 million in 1996 and $15
million in 1995. These amounts include rent expense paid to related parties of
$1 million during each of 1997, 1996 and 1995.

Future minimum rental commitments as of December 31, 1997 under noncancelable
capital and operating lease agreements are as follows:

NOTE G -- 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.

FORWARD FOREIGN EXCHANGE CONTRACTS: The fair values of the Company's forward
foreign exchange contracts, which amounted to $177 million at December 31, 1997
and which were immaterial at December 31, 1996, are based on quoted market
prices of comparable contracts.

The carrying amounts and fair values of the Company's financial instruments at
December 31, 1997 and 1996 are as follows:



                                        1997                        1996

At December 31, 1997, the Company had U.S. tax net operating loss carryforwards
and research and development tax credits of approximately $17 million that will
expire periodically beginning in the year 2002. In addition, the Company had
foreign net operating loss carryforwards of $12 million that will expire
periodically beginning in the year 2000. The Company established a valuation
allowance of $23 million for these carryforwards primarily attributable to the
carryforwards acquired as part of the Company's 1995, 1996 and 1997 mergers and
acquisitions.

Income taxes paid amounted to $89 million in 1997, $85 million in 1996 and $83
million in 1995.

NOTE I -- STOCKHOLDERS' EQUITY

PREFERRED STOCK: The Company is authorized to issue 25 million shares of
preferred stock in one or more series and to fix the powers, designations,
preferences and relative, participating, option or other rights thereof,
including dividend rights, conversion rights, voting rights, redemption terms,
liquidation preferences and the number of shares constituting any series,
without any further vote or action by the Company's stockholders. At December
31, 1997, the Company had no shares of preferred stock outstanding.

COMMON STOCK: The Company is authorized to issue 300 million shares of common
stock, $.01 par value per share. Holders of common stock are entitled to one
vote per share. Holders of common stock are entitled to receive dividends when
and if declared by the Board of Directors and to share ratably in the assets of
the Company legally available for distribution to its stockholders in the event
of liquidation. Holders of common stock have no preemptive, subscription,
redemption or conversion rights. The holders of common stock do not have
cumulative voting rights. The holders of a majority of the shares of common
stock can elect all of the Directors and can control the management and affairs
of the Company.

The Company is authorized to purchase on the open market up to approximately 20
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. During 1997, the
Company repurchased approximately

                 BOSTON SCIENTIFIC CORPORATION AND SUBSIDIARIES
   35
3.5 million shares of its common stock at an aggregate cost of $188 million.
Prior to 1997, a total of 6.5 million shares of the Company's common stock was
repurchased under the program.

As part of the stock repurchase program, the Company has been selling European
equity put options to an independent broker-dealer. Each option, if exercised,
obligates the Company to purchase from the broker-dealer a specified number of
shares of the Company's common stock at a predetermined exercise price. The put
options are exercisable only on the first anniversary of the date the options
were sold. Proceeds are recorded as a reduction to the cost of the Company's
treasury stock. During 1996, the Company sold European put options for 600,000
shares and received proceeds of approximately $3 million. The put options for
these 600,000 shares expired during 1997. During 1997, the Company sold put
options for 329,000 shares and received proceeds of approximately $2 million.
Repurchase prices relating to put options outstanding at December 31, 1997
range from $55 per share to $56 per share. The Company's contingent obligation
to repurchase shares upon exercise of the outstanding put options approximated
$18 million at December 31, 1997.


NOTE J -- STOCK OWNERSHIP PLANS

EMPLOYEE AND DIRECTOR STOCK OWNERSHIP PLANS

Boston Scientific's 1992 and 1995 Long-Term Incentive Plans provide for the
issuance of up to 20 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
(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 7,500 shares, 1,000
shares and 29,000 shares were issued to employees during 1997, 1996 and 1995,
respectively.

Boston Scientific's 1992 Non-Employee Directors' Stock Option Plan provides for
the issuance of up to 100,000 shares of common stock and authorizes the
automatic grant to outside directors of options to acquire 2,000 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 24 million at December 31, 1997.

If the Company had elected to recognize compensation expense for the granting
of options under the aforementioned 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 and earnings per share
would have been reported as the following pro forma amounts:

The weighted average grant-date fair value of options granted during 1997, 1996

The fair value of the stock options used to calculate the pro forma net income
and earnings per share amounts above is estimated using the Black-Scholes
options pricing model with the following weighted average assumptions:

The effects of expensing the estimated fair value of stock options on 1997,
1996 and 1995 pro forma amounts are not necessarily representative of the
effects on reporting the results of operations for future years as the periods
presented include only one, two and three years of option grants under the
Company's plans.

STOCK PURCHASE PLAN

Boston Scientific's 1992 Employee Stock Purchase Plan (Stock Purchase Plan)
provides for the granting of options to purchase up to 1.5 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 a
number of shares equal to not more than 10% of the employee's eligible
compensation divided by 85% of the fair market value of the Company's common
stock as of the beginning of that offering period. Such options may be exercised
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 1997, approximately 120,000 shares were issued at prices ranging from
$46.909 to $48.663 per share. During 1996, approximately 120,000 shares were
issued at prices ranging from $36.125 to $39.419 per share, and, during 1995,
approximately 133,000 shares were issued at prices ranging from $13.60 to
$21.463 per share. At December 31, 1997, there were approximately 970,000
shares available for future issuance.

NOTE L -- COMMITMENTS AND CONTINGENCIES

Beginning in 1993, Schneider (Europe) AG and Schneider (USA) Inc., subsidiaries
of Pfizer, Inc., alleged that the Company's Synergy (TM) products infringe one
of their patents. On May 13, 1994, the Company filed a lawsuit against them in
the U.S. District Court for the District of Massachusetts seeking a declaratory
judgment that this patent is invalid and that the Company's Synergy products do
not infringe the patent. The Company subsequently amended its complaint to seek
a declaratory judgment that the patent is unenforceable. The Schneider companies
filed counterclaims against the Company, alleging the Company's willful
infringement of the patent and seeking monetary and injunctive relief. In
October 1997, the District Court granted the Company's motion for summary
judgment on noninfringement, and ruled that the Company cannot litigate the
issues of validity and enforceability, which had previously been litigated by
SCIMED Life Systems, Inc. (SCIMED), the Company's subsidiary. Both parties have
filed notices of appeal. The Company ceased marketing its Synergy catheters in
August 1996.

On May 31, 1994, SCIMED 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 FLOWTRACK-40 (TM) and RX ELIPSE (TM) PTCA
catheters. On November 17, 1995, SCIMED filed a suit for patent infringement
against ACS, alleging willful infringement of three of SCIMED's U.S. patents by
the ACS RX LIFESTREAM (TM) PTCA catheter. Both suits were filed in the U.S.
District Court for the Northern District of California seeking monetary and
injunctive relief. The cases were sent to consolidated arbitration for a
threshold determination of one issue covered by the November 27, 1991 settlement
agreement between the parties. On March 14, 1997, the arbitration panel reached
a final determination in the consolidated arbitration. Pursuant to this
determination, the Company is continuing its action as to the ELIPSE product and
has dismissed the actions as to the FLOWTRACK and LIFESTREAM products. ACS has
answered, denying the allegations of the complaint. In January 1998, the Company
moved to add the ACS RX MULTILINK (TM) (stent delivery system) to its complaint.
Trial is scheduled to begin in late 1998 or early 1999.

     SCIMED has also accused ACS's RX MULTILINK HP (TM) stent delivery system
and ACS's RX ROCKET (TM) and RX COMET (TM) PTCA catheters of infringing several
SCIMED patents. These claims, as well, are subject to arbitration relating to a
threshold determination under the November 27, 1991 settlement agreement. The
hearing in the combined arbitration on these products is scheduled to begin on
May 11, 1998. If SCIMED is successful in the arbitration, it intends immediately
to commence patent infringement litigation to enforce its rights under the
relevant patents against ACS.

On October 10, 1995, ACS filed a suit for patent infringement against SCIMED,
alleging willful infringement of four U.S. patents licensed to ACS by SCIMED'S
EXPRESS PLUS (TM) and EXPRESS PLUS II (TM) PTCA catheters. 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 scheduled to begin in November 1998.

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 (TM) 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 complaint. Trial is
scheduled to begin in November 1998 as to the EXPRESS PLUS products and January
1999 as to the BANDIT product.

On December 15, 1995, the Company and SCIMED filed a suit for restraint of
trade, unfair competition and conspiracy to monopolize against ACS and the
Schneider companies, alleging certain violations of state and federal antitrust
laws aris-

ing from the improper prosecution, enforcement and cross-licensing of U.S.
patents relating to rapid exchange balloon dilatation angioplasty catheters.
Suit was filed in the U.S. District Court for the District of Massachusetts and
seeks monetary, declaratory and injunctive relief. In October 1997, the court
granted the defendants' motion to dismiss. The Company has filed a notice of
appeal.

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.

On November 9, 1994, Target Therapeutics, Inc. (Target) filed a lawsuit in the
U.S. District Court for the Northern District of California alleging that
SCIMED's VENTURE(R) and VENTURE II(TM) microcatheters and Cordis Corporation's
(Cordis) TRANSIT(R) and RAPIDTRANSIT(TM) microcatheters infringe a patent
assigned to Target. On May 2, 1996, the District Court entered an order granting
a preliminary injunction to Target prohibiting SCIMED and Cordis from marketing
or selling the accused products. On July 1, 1996, the Court of Appeals for the
Federal Circuit stayed the preliminary injunction pending a decision on SCIMED's
appeal of the District Court's order. Upon the recent merger between the Company
and Target, the lawsuit was dismissed as to the Company. Subsequently, the Court
of Appeals vacated the preliminary injunction. The lawsuit was dismissed as to
Cordis pursuant to a Settlement Agreement signed January 9, 1998.

On October 3, 1995, Cordis Endovascular, Inc. and Cordis filed a suit alleging
patent infringement against Target Therapeutics, Inc. (Target) alleging that
Target's DASHER(R) guidewires, FASGUIDE(R) catheters and TRACKER(R) and
FASTRACKER(R) guide microcatheters infringe three patents owned by Cordis. The
lawsuit was dismissed pursuant to a Settlement Agreement signed January 9, 1998.

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. The lawsuit seeks a declaratory judgment that the Company has infringed
the Bard patent, preliminary and permanent injunctions enjoining the
manufacture, use or sale of the MaxForce TTS catheter or any other infringing
product, monetary damages and expenses. After a jury trial in June 1997, the
jury returned a verdict finding that the Company infringed the Bard patent and
awarded damages to Bard in the amount of $10.8 million. No judgment has been
entered pending trial on the Company's claim that the patent was obtained by
inequitable conduct. The Company intends to appeal any judgment entered on the
jury verdict. The Company no longer markets the accused devices.

On February 28, 1997, C.R. Bard, Inc. (Bard) filed a suit for patent
infringement against SCIMED alleging that SCIMED's WAVE(TM) and SURPASS(TM)
catheters are infringing a patent assigned to Bard. The suit was filed in the
U.S. District Court for the District of New Jersey seeking monetary and
injunctive relief. The lawsuit was dismissed pursuant to a Settlement Agreement
signed December 4, 1997.

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. The court has requested that an expert be named to provide the
court technical advice, and the parties have submitted suggestions; an expert
has not yet been chosen.

On March 25, 1996, Cordis filed a suit for patent infringement against SCIMED,
alleging the infringement of five U.S. patents by SCIMED's LEAP(TM) 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 scheduled for June
1998.

On March 13, 1997, the Company (through its subsidiaries) filed suits in The
Netherlands and the United Kingdom, and on March 17, 1997 filed suit in France,
seeking a declaration of noninfringement for the Company's LEAP balloon in
relation to a European patent owned by Cordis. The United Kingdom suit has been
dismissed for lack of controversy and the Netherlands suit has been withdrawn. A
decision in the suit in France is expected late in 1998.

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). A response is expected in April 1998. The Company appealed
the court's decision to present questions to the EPO. A hearing on the appeal is
set for June 16, 1998.

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 scheduled for November 1998.

On December 13, 1996, the Superior Court of the State of Arizona granted the
motion of Impra, Inc. (Impra) to add the Company as an additional defendant in
Impra's case against Endomed, Inc. (Endomed). Impra (now a subsidiary of C.R.
Bard, Inc.) alleges that Endomed misappropriated certain Impra trade secrets and
that the Company acted in concert with Endomed to utilize the technology. On the
same date, Endomed and the Company were preliminarily enjoined, among other
things, from any further use or disclosure of the technology. The Company has
answered, denying the allegations of the complaint. Trial is scheduled to begin
in April 1998.

On March 13, 1997, the Company (through its subsidiaries) filed suits against
Johnson & Johnson Company (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(TM) 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. Trial begins in the United Kingdom on March 23, 1998. On March 18,
1997, the Company (through its subsidiary) filed a similar suit in Germany, but
seeking only a declaration of noninfringement for the NIR stent relative to the
two patents. 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 stent relative to one of the European patents
licensed to Ethicon and a declaration of invalidity in relation to that patent
(in Italy and Spain only). Ethicon and other Johnson & Johnson subsidiaries
filed a cross-border suit in The Netherlands on March 17, 1997, alleging that
the NIR 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. The Johnson & Johnson entities thereafter filed a similar cross-border
proceeding in The Netherlands with respect to the 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 stent will be
found not to infringe the patents. Johnson & Johnson has appealed this decision
with respect to one of the patents. A hearing on Johnson & Johnson's appeal of
the denial of relief is expected to be held on March 10, 1998; a hearing on the
merits is expected late in 1998.

On May 6, 1997, Ethicon Endosurgery, Inc. sued the Company in Dusseldorf,
Germany, alleging that its NIR stent infringes one of Ethicon's patents. A
hearing is scheduled for June 19, 1998.

On March 13, 1997, the Company filed a Motion to Intervene in Johnson & Johnson
Interventional Systems Co. et al. v. Cook, Incorporated et al., an action in the
U.S. District Court for the Southern District of Indiana. The motion seeks
intervention for the purpose of modifying the present protective order to
direct the Clerk of Court to retain, and the parties and their counsel not to
destroy, materials and testimony assembled in that action. By agreement, the
Company is receiving access to the documents and materials.

On June 16, 1997, the Company and SCIMED filed a suit against Johnson & Johnson
and related entities in the U.S. District Court for the District of
Massachusetts seeking a declaratory judgment of noninfringement for the NIR
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. In October 1997, Johnson & Johnson's motion to
dismiss the suit was denied. Johnson & Johnson has answered, denying the
allegations of the complaint, and counterclaiming for patent infringement. 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 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 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 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.

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 par-

ticular 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.

During 1997, the Company recorded approximately $34 million of
litigation-related reserves to cover costs of defense and settlement, and
unfavorable outcomes. The reserves are included in selling, general and
administrative expenses.

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 M -- BUSINESS COMBINATIONS

In 1997, the Company increased to approximately 25% its voting ownership in
Medinol, Ltd. (Medinol), a developer of innovative technologies for
cardiovascular applications. Accordingly, the Company has retroactively applied
the equity method of accounting to account for this investment which had been
accounted for under the cost method since 1995, the year of the Company's
original investment. This accounting had the effect of increasing the amount of
the previously reported charges for purchased research and development and
reducing net earnings in 1995 by $35 million, or approximately $0.18 per share.
The effect of this change in 1996 and 1997 was not significant.

In 1997, Boston Scientific consummated its merger with Target. The acquisition
is accounted for as a pooling-of-interests (see Note A), thus, the combined
consolidated financial statements serve as the basis for historical financial
statements of Boston Scientific. Combined and separate results of Boston
Scientific and Target for 1996 and 1995 are as follows:



                                                                        Combined

Target's net sales, gross profit and net income for the three months ended March
31, 1997 were approximately $31 million, $24 million and $2 million,
respectively. The restated financial data is not necessarily indicative of the
operating results or financial position that would have occurred if the Target
merger had been consummated during the periods presented, nor is it necessarily
indicative of future operating results or financial position.


NOTE N -- MERGER-RELATED CHARGES AND EXPENSES

In 1997, the Company recorded merger-related charges of $175 million ($135
million, net-of-tax). Charges include $29 million for purchased research and
development recorded in conjunction with accounting for the Company's additional
investment in Medinol ($12 million) and the Company's other strategic
acquisitions ($17 million), $16 million in direct transaction costs and $96
million of estimated costs to be incurred in merging the separate operating
business of Target with subsidiaries of the Company. The remaining amounts
represent primarily adjustments to merger-related charges recorded in 1996 and
1995 based on actual costs incurred or changes in estimates (approximately $15
million) and write-downs of assets in connection with the Company's
implementation of a global information system.

In connection with the mergers and acquisitions consummated in 1996 and 1995
(see Note A) and the Company's initial investment in Medinol, the Company
recorded merger-related charges of $142 million ($128 million, net-of-tax) and
$272 million ($231 million, net-of-tax), respectively.

Estimated costs include those typical in a merging of operations and relate to,
among other things, rationalization of facilities, workforce reductions,
unwinding of various contractual commitments, asset write-downs and other
integration costs. The merger-related charges are determined based on formal
plans approved by the Company's management using the best information available
to it at the time. The workforce-related initiatives involve substantially all
of the Company's employee groups. The amounts the Company may ultimately incur
may change as the plans are executed.

================================================================================


Most of the plans are expected to be completed by the end of 1998. Cash outlays
to complete the balance of the Company's initiative to integrate the businesses
related to all mergers and acquisitions consummated since 1994 are estimated to
be approximately $59 million.



NOTE O -- FINANCIAL INFORMATION BY GEOGRAPHIC AREA

Boston Scientific is a worldwide developer, manufacturer and marketer of medical
devices for less invasive procedures and operates in one segment. Sales between
geographic areas are made at prices which would approximate transfers to
unaffiliated distributors. In the presentation below, the profit derived from
such transfers is attributed to the area in which the sale to the unaffiliated
customer is eventually made. Because of the interdependence of the geographic
areas, the operating profit as presented may not be representative of the
geographic distribution which would occur if the areas were not interdependent.
In addition, comparison of operating results between geographic areas and
between years may be impacted by foreign currency fluctuations.

BOARD OF DIRECTORS
BOSTON SCIENTIFIC CORPORATION

We have audited the accompanying consolidated balance sheets of Boston
Scientific Corporation and subsidiaries as of December 31, 1997 and 1996, and
the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period ended December 31, 1997.
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, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

As more fully described in Note B, 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.

The Company has never paid dividends, other than in March 1992, when the Company
paid a one-time dividend of an aggregate of $20 million, or $0.212 per share,
to holders of common stock. The $0.212 per share is based on Boston
Scientific's weighted average number of the common shares outstanding at the
time the dividend was declared rather than the restated weighted average number
of the common shares outstanding.

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, 1997, there were approximately 9,300 record holders of the
Company's common stock.
