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

                   AGREEMENT AND GENERAL RELEASE OF ALL CLAIMS

         This Agreement and General Release of All Claims ("Agreement") is
entered into by and between Robert G. MacLean ("You" or "Employee") and Boston
Scientific Corporation ("Boston Scientific") as of the latest date of execution
by the parties to this Agreement. This Agreement is subject to the approval of
the Boston Scientific Board of Directors or a designated committee thereof. This
Agreement shall not become final or effective until the Effective Date (as
defined in Paragraph 6(d), below). This Agreement supersedes and cancels any
prior employment agreements or arrangements You may have entered into with
Boston Scientific.

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

         1.       RETIREMENT FROM EMPLOYMENT
                  --------------------------

                  You hereby acknowledge and agree that You are retiring from
your position as Executive Vice President, Human Resources, and as an employee
of Boston Scientific effective March 31, 2005 ("Retirement Date").

         2.       PAYMENTS BY BOSTON SCIENTIFIC
                  -----------------------------

                  (a) Within two (2) weeks of the Effective Date of this
Agreement or your Retirement Date, whichever is later, Boston Scientific will
pay to You one (1) lump sum payment in twice the amount of your current Boston
Scientific base annual salary of Three Hundred Eighty Thousand Thirty-Six
Dollars and Fifty-Four Cents ($380,036.54), for a total gross amount of Seven
Hundred Sixty Thousand Seventy-Three Dollars and Eight Cents ($760,073.08), less
applicable payroll withholding for taxes and other applicable deductions. You
expressly acknowledge that upon the occurrence of the Retirement Date, You will
not be eligible for any payments or benefits in addition to those described in
this Agreement under any existing Boston Scientific Severance Pay Plan and/or
Layoff Notification Plan.

                  (b) Boston Scientific will pay You for all accrued but unused
vacation time through the Retirement Date under applicable Boston Scientific
policy and in accordance with applicable state law.

                  (c) Boston Scientific will pay You within two (2) weeks of the
Effective Date of this Agreement or your Retirement Date, whichever is later, an
amount equivalent to an incentive payment under Boston Scientific's 2005
Performance Incentive Plan at the rate of twenty percent (20%) of your current
Boston Scientific base annual salary. You will not be

                                       1
<PAGE>

eligible for consideration for incentive payments under any future Performance
Incentive Plan, and you hereby waive any right to such consideration or such
payments.

         3.       TERMINATION OF EMPLOYMENT BENEFITS
                  ----------------------------------

                  (a) You agree and acknowledge that your participation in
Boston Scientific's 401(k) Plan, Stock Option Plan(s), and Global Employee Stock
Ownership Plan, if any, Accidental Death and Dismemberment (AD&D), Business
Travel Accident, Life Insurance, Short-Term and Long-Term Disability Plans will
terminate as of your Retirement Date, as will your accrual of vacation time. You
further agree and acknowledge that You will participate through the Retirement
Date in all other benefits and benefit plans in which You are currently enrolled
to the same extent as do other active employees and that your participation in
and entitlement to any and all other benefits and benefits plans in which You
are currently enrolled, but which are not otherwise specifically addressed in
this Agreement, terminate on the Retirement Date.

                  (b) Boston Scientific will provide You with health care
coverage to Age 65 as follows:

                      (i) If, before you turn Age 65, Boston Scientific
implements an executive retiree health, i.e. medical plan, You (as well as any
of your dependents who were covered through your participation in the
Consolidated Omnibus Budget and Reconciliation Act of 1986 ("COBRA") as
described below) will be eligible to participate in that plan, under all
applicable terms and conditions, once your eligibility to receive benefits under
COBRA ends. You understand that the terms of any such retiree health, i.e.
medical plan, may change from time to time and that your coverage and/or
participation, and associated contribution costs will be subject to any such
change (including, if applicable, a shared premium responsibility as described
in (ii) immediately below);

                      (ii) Your participation in Boston Scientific's Medical and
Dental Plans and Healthcare Reimbursement Account (as well as the participation
of any of your dependents who were covered by such Plans or Account one month
prior to the Retirement Date) shall continue on the same terms and conditions as
such coverage and/or participation is made available from time to time to Boston
Scientific employees generally under the terms and conditions of COBRA. Boston
Scientific will pay the employer's portion of the costs for any such medical and
dental coverage for the period of time such coverage is provided under COBRA,
should You be eligible for it. To enable Boston Scientific to comply with its
obligation to provide notification of your rights to continue Medical and Dental
Plan coverage and/or Healthcare Reimbursement Account participation, You agree
to inform Boston Scientific of any change in address, dependent or marital
status. You further agree to inform Boston Scientific immediately if, before the
end of the COBRA eligibility period, you become eligible for any other group
health coverage, and of the type and amount of such coverage, as well as to
promptly respond to any inquiries from Boston Scientific regarding other group
health coverage. You also acknowledge that You understand that the terms of
Boston Scientific's Medical and Dental Plans

                                       2
<PAGE>

and Healthcare Reimbursement Account offered to Boston Scientific employees
generally may change from time to time, and that your coverage and/or
participation and associated contribution costs will be subject to any such
change.

                      (iii) Should your eligibility to participate in COBRA, as
described in (ii) immediately above, never mature or cease before you turn Age
65 and should Boston Scientific not have implemented an executive retiree
health, i.e. medical plan at the time of that failure to mature or cessation,
You will then have the option of obtaining on the open market, as available,
medical insurance comparable to that supplied by Boston Scientific and with a
shared premium responsibility as described in (ii) immediately above.

                      (iv) When your coverage under any of the above plans ends
because You reach Age 65 or otherwise, your dependents, if any, will retain no
continued eligibility to participate in any of those plans, except as required
by law.

                  (c) Paragraph 3(a) notwithstanding, Boston Scientific will
continue to make annual bonus payments to Employee equal to the amount of the
premium payments for the Security Life of Denver Insurance Company universal
life insurance policy currently covering Employee (the "life insurance policy")
for as long as the life insurance policy remains in effect, but not later than
December 31, 2008 or Employee's death, whichever is earlier, plus a grossed up
amount for tax purposes. Employee or his trust or designee will remain
responsible for making premium payments on the life insurance policy itself.
Employee and Boston Scientific agree that Boston Scientific is not responsible
for maintaining, administering or making payments under or for any other
obligation under the life insurance policy itself and that Boston Scientific's
obligation with respect to the life insurance policy extends solely to the
payment of the bonus amounts set forth herein. Employee agrees to provide Boston
Scientific with documentation as may from time to time be requested to enable
Boston Scientific to effectuate this provision, including but not limited to
proof of coverage, premium statements and tax information necessary to calculate
the gross up amount.

                  (d) Any unvested portions of previously awarded stock option
grants will continue to vest through the Retirement Date and will become
exercisable under the terms and conditions contained in the applicable option
agreement(s) and plan document(s).

         4.       EXPENSE REIMBURSEMENT
                  ---------------------

                  Boston Scientific will reimburse You in accordance with usual
Boston Scientific policy for all unreimbursed business travel and other
out-of-pocket expenses incurred by You through the Retirement Date in the
performance of your duties as an employee of Boston Scientific. Such expenses
must be submitted within two (2) weeks after the Retirement Date.

                                       3
<PAGE>

         5.       PURCHASE OF CURRENTLY LEASED AUTOMOBILE
                  ---------------------------------------

                  Boston Scientific agrees that, on or within a reasonable
period of time after your Retirement Date, You may purchase at fair market value
the leased 2000 Ford Explorer currently in your possession through Boston
Scientific's automobile leasing program. Any tax obligations associated with
this purchase will be your personal responsibility.

         6.       RELEASE BY EMPLOYEE
                  -------------------

                  Employee hereby releases and forever discharges Boston
Scientific and its subsidiaries, affiliates, predecessors, successors, and
assigns and the Directors, officers, shareholders, insurers, plans, employees,
representatives and agents of each of the foregoing (collectively "Releasees")
of and from the following as of the date of Employee's execution of this
Agreement:

                  (a) Any and all claims, demands, and liabilities whatsoever of
every name and nature (other than those arising directly out of this Agreement),
including (without limitation) any claim in the nature of so-called
whistleblower complaints to the extent permitted by applicable law, and any and
all claims, demands and liabilities with respect to Employee's employment or the
terms and conditions of his employment, benefits or compensation which Employee
has against Releasees, or ever had;

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

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

                  (d) Employee acknowledges that he has been given the
opportunity, if he so desires, to consider this Agreement for twenty-one (21)
days before executing it. In the event that Employee executes the Agreement
within less than twenty-one (21) days of the date of its delivery to him, he
acknowledges that such decision was entirely voluntary and that he had the
opportunity to consider this Agreement for the entire twenty-one (21) day
period. Boston Scientific acknowledges that for a period of seven (7) days from
the date of the execution of this Agreement, Employee shall retain the right to
revoke this Agreement by written notice to Boston Scientific, c/o James R.
Tobin, President and CEO, Boston Scientific Corporation, One Boston

                                       4
<PAGE>

Scientific Place, Natick, Massachusetts, 01760, or his successor, and that this
express Agreement shall not become final, effective or enforceable until the
date upon which both of the following conditions have been met: (i) such
revocation period expires and (ii) the Board of Directors or a designated
committee thereof has approved this Agreement (the "Effective Date"). Therefore,
no Boston Scientific obligations will be met and payments called for by Boston
Scientific under Paragraphs 2(a), 2(c), 3(b), 3(c) and 11(b) above, shall not be
made until the Effective Date (or the Retirement Date, if later).

         7.       NO DAMAGES SOUGHT
                  -----------------

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

         8.       NO LIABILITY ADMITTED
                  ---------------------

                  Employee acknowledges that neither Boston Scientific's
execution of this Agreement nor Boston Scientific's performance of any of its
terms shall constitute an admission by Boston Scientific of any wrongdoing by
any of the Releasees.

         9.       NONDISCLOSURE OF CONFIDENTIAL INFORMATION;
                  ------------------------------------------
                  RETURN OF BOSTON SCIENTIFIC PROPERTY
                  ------------------------------------

                  (a) Employee shall keep entirely secret and confidential, and
shall not disclose to any person or entity, in any fashion or for any purpose
whatsoever, any information that is (i) not available to the general public,
and/or (ii) not generally known outside Boston Scientific, regarding Releasees,
to which he has had access or about which he heard during the course of his
employment by Boston Scientific or during the Consulting Services Period in
connection with his performance of the Consulting Services (described in
Paragraph 11, below), including (without limitation) any information relating to
any of the Releasees' business or operations; their plans, strategies, prospects
or objectives; their products, technology, processes or specifications; their
research and development operations or plans; their customers and customer
lists; their manufacturing, distribution, procurement, sales, service, support
and marketing, clinical, regulatory and quality practices and operations; their
financial conditions and results of their operations; their operational
strengths and weaknesses; and their personnel and compensation policies,
procedures and transactions ("Boston Scientific Confidential Information").

                  (b) Employee agrees to return to Boston Scientific, on or
before the Retirement Date, except as Boston Scientific may specifically provide
to him or allow him to retain during the Consulting Services Period in
connection with his performance of the

Consulting Services, and except as to the Office Equipment described in
Paragraph 9(c), below, documents or media of whatever nature, including

form, any property provided to or produced by him, including without limitation
all samples, reports, communications, drawings, notes and analyses, any property
passes, keys, credit cards, business cards, identification badges, and all
sample and demonstration products, provided to or produced by him (the "Boston

                  (c ) As additional consideration for entering into this
Agreement, Boston Scientific hereby transfers ownership of the Palm Pilot,
laptop computer, Blackberry and cell phone (collectively, the "Office
Equipment") provided to Employee during his employment in connection with his
job duties prior to his Retirement Date. Boston Scientific agrees that the
Office Equipment does not fall within the definition of Boston Scientific
Property described in Paragraph 9(b), above. Employee hereby warrants that he
will, prior to his Retirement Date, coordinate with Boston Scientific to remove
from the Office Equipment: (1) any Boston Scientific Confidential Information;
and (2) other information related to his employment by Boston Scientific to the
extent requested.

         10.      NO DETRIMENTAL COMMUNICATIONS
                  -----------------------------

                  Employee agrees that he will not make or cause to be disclosed
any negative, adverse or derogatory statements to any media outlet, industry
group, financial institution or current or former employee, consultant, client
or customer of the Releasees regarding any of the Releasees or about any of the
Releasees' products or services, business affairs, financial condition or
prospects for the future. Furthermore, Employee hereby represents to Boston
Scientific that he has made no such communication, and Employee acknowledges
that Boston Scientific relies upon this representation in agreeing to enter into
this Agreement.

         11.      FUTURE ASSISTANCE/CONSULTING SERVICES
                  -------------------------------------

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

                  (b) Employee hereby specifically agrees that he will provide
up to fifty (50) days of transition and project assistance to Boston Scientific
with respect to (I) the provision of advice, guidance, background information
and related assistance in connection with the "Service Excellence" (HR

                                       6
<PAGE>

Human Resources and line functions related to problem resolution and acquisition
of new businesses in Boston Scientific's West Coast operations during the time
period from his Retirement Date through March 31, 2006 and Boston Scientific
shall, within two (2) weeks of the Effective Date of this Agreement or the
Retirement Date, whichever is later, pay Employee a lump sum amount of One
Hundred Thousand Dollars ($100,000) for such services. Boston Scientific may
request that Employee provide additional days of service during the time period
from his Retirement Date through March 31, 2006 and shall pay Employee for such
additional days of service at a rate of Three Thousand Dollars and Zero Cents
($3,000.00) per day. Boston Scientific and Employee may mutually agree in
writing to continue to engage Employee to provide such services for one
additional year (from April 1, 2006 through March 31, 2007), in which case
Boston Scientific shall pay Employee at a rate of Two Thousand Dollars and Zero
Cents ($2,000.00) per day for such services provided during that time. Boston
Scientific also agrees to pay Employee's reasonable travel expenses incurred in
the course of providing all such services (although Boston Scientific shall not
reimburse him for office expenses incurred in the course of providing such
services and shall not maintain an office for Employee after his Retirement
Date). Employee agrees to provide detailed records and substantiation of all
such services and reasonable travel expenses and to invoice Boston Scientific
for them, by delivery of such invoice to the President of Boston Scientific or
his designee, by the first business day of the quarter following the quarter in
which they are performed. Boston Scientific agrees to pay Employee within thirty
(30) days of receipt of such invoice. All services provided within the scope of
this Paragraph 11(b) shall be limited and relate solely to advice and assistance
to Boston Scientific with respect to (b) (I) and (II) above, and within his area
of expertise, as well as special limited and defined projects arising therefrom
(the "Consulting Services") and shall be coordinated through the President of
Boston Scientific or his designee. If Employee provides the Consulting Services
only during the time period from his Retirement Date through March 31, 2006,
that time period shall be the "Consulting Services Period." If Employee provides
any Consulting Services during the time period from April 1, 2006 through March
31, 2007, then the entire time period from his Retirement Date through March 31,
2007 shall be the "Consulting Services Period." Employee understands, represents
and warrants that he:

                      (i) shall be engaged as an independent contractor and not
as an employee of Boston Scientific during the Consulting Services Period (the
use of the defined term "Employee" for drafting purposes only in this overall
Agreement notwithstanding);

                      (ii) shall as to the amounts set forth in this Paragraph
11(b) and paid for the Consulting Services, be responsible for payment of all
federal, state and local taxes including but not limited to income, Social
Security, unemployment, disability and other taxes;

                      (iii) during the Consulting Services Period, shall have no
right to bind Boston Scientific in any manner without the express written
consent of the President of Boston Scientific or his designee, and that he is
not entitled to any benefits for which Boston Scientific employees are eligible,
unless otherwise expressly set forth in this Agreement;

                                       7
<PAGE>

                      (iv) as of the date this Agreement is executed, is not
excluded, debarred, suspended, or otherwise ineligible to participate in U.S.
government health care programs (e.g., Medicare, Medicaid, CHAMPUS) or U.S.
government procurement and non-procurement programs, and if at any time during
the Consulting Services Period, he becomes so excluded, debarred, suspended or
otherwise ineligible, he will immediately disclose such information to the
President of Boston Scientific;

                      (v) during the Consulting Services Period, has the
unrestricted right to disclose any third-party information he submits to Boston
Scientific in the performance of the Consulting Services and that the Consulting
Services do not violate any agreement with other parties or other restrictions
of any kind, and that he shall not disclose to Boston Scientific any
confidential or proprietary information belonging to any third party or
represent as unrestricted any data of any kind that he knows to be covered by
valid patent, copyright or other form of intellectual property protection;

                      (vi) will abide by the confidentiality obligations set
forth in Paragraph 9(a) of this Agreement in the performance of the Consulting
Services and thereafter and shall not, without Boston Scientific's prior written
consent, disclose or use any Boston Scientific Confidential Information, except
as requested by Boston Scientific;

                      (vii) agrees that all tangible property provided to or
produced by him during the Consulting Services Period, including without
limitation all samples, reports, communications, drawings, notes, analyses and
materials received from Boston Scientific or produced in connection with the
Consulting Services, shall fall within the definition of Boston Scientific
Property and shall remain the exclusive property of Boston Scientific; Employee
further agrees to maintain any Boston Scientific Property provided to or
produced by him in connection with the Consulting Services in his custody and
control and to return it at the conclusion of the Consulting Services Period or
upon Boston Scientific's request;

                      (viii) agrees that during the Consulting Services Period
and for one (1) year thereafter, will promptly report and disclose to Boston
Scientific all improvements to Boston Scientific's products and/or services
tested and evaluated by him and all ideas and concepts heard, developed or
conceived, either alone or with others, including any ideas and concepts which
result in new products or significant enhancements to existing products, while
performing the Consulting Services ("Developments"). Developments shall be the
sole and exclusive property of Boston Scientific and are hereby assigned to
Boston Scientific without any additional payments by Boston Scientific. It is
understood that Boston Scientific shall have the right but not the obligation to
initiate, prosecute, maintain and defend any and all patentable ideas and
concepts with respect to Developments. Employee shall provide reasonable
assistance to Boston Scientific with respect to any such patents and patent
applications, and shall execute all appropriate documents and assignments with
respect to any such patents and patent applications. Employee agrees not to
assert any rights in law or in equity in the Developments;

                                       8
<PAGE>

                      (ix) during the Consulting Services Period and for one (1)
year thereafter, shall submit to Boston Scientific any paper he intends to
publish relating in any way to the Consulting Services or the subject matter
thereof, and shall not submit any such paper to a publisher or other party prior
to the expiration of forty-five (45) days from the date an outline of the paper
is submitted to Boston Scientific. If Boston Scientific determines in good faith
during such period that publication or presentation of such paper would be
detrimental to its intellectual property interests, Employee shall work in good
faith with Boston Scientific to retract or modify the paper to remove all
language which is detrimental to Boston Scientific's intellectual property or
other interests, or, in the alternative and at Boston Scientific's election,
shall refrain from submitting such paper to a publisher or other party for an
additional 120 days to permit Boston Scientific to file patent applications or
take other steps to protect its intellectual property or other interests. During
the Consulting Services Period and for a period of one (1) year thereafter,
Employee shall also submit to Boston Scientific for review, on a confidential
basis, any patent applications relating to the Consulting Services naming
Employee as an inventor, either alone or with others, which Employee or any
third party intends to file with any U.S. or international patent offices in
advance of the filing of any such application. Boston Scientific shall have
thirty (30) days in which to review such applications. If Boston Scientific
makes a good faith determination, within such period, that the filing of such an
application would be contrary to its intellectual property rights set forth
herein, Employee shall amend, or cause to be amended, such proposed patent
application to remove any language that is determined by Boston Scientific to be
contrary to its intellectual property rights hereunder; and

                      (x) agrees to indemnify Boston Scientific and hold Boston
Scientific harmless from any suits, claims, actions, damages or losses
whatsoever (including attorneys' fees) arising out of any claim that any use of
the Developments by Boston Scientific infringes any copyright or patent or
otherwise violates any third party rights; resulting in any way from any of his
acts or omissions in the performance of the Consulting Services or his presence
at a Boston Scientific facility; and for any obligations imposed by law on
Boston Scientific to pay any taxes, Social Security, unemployment or disability
insurance or other items in connection with payments made to him under this
Paragraph 11(b) in connection with the Consulting Services.

         12.      HIRING OF BOSTON SCIENTIFIC EMPLOYEES
                  -------------------------------------

                  During the period beginning as of the Retirement Date and for
twenty-four (24) months thereafter, Employee shall not attempt to or actually
hire away any individual who is an employee or was an employee of Boston
Scientific or any of the Releasees within the twelve (12) month period
immediately preceding the Retirement Date, assist in the hiring away of any such
employee by another person, or encourage any such employee to terminate their
employment with Boston Scientific or any of the Releasees, whether directly or
indirectly, unless the President of Boston Scientific or his designee shall have
given prior written approval.

                                       9
<PAGE>

         13.      POST-SEPARATION NON-COMPETITION RESTRICTION
                  -------------------------------------------

                  During the period beginning as of the Retirement Date and for
twenty-four (24) months thereafter, Employee agrees that he shall not, directly
or indirectly, without the written consent of the President of Boston Scientific
or his designee, engage in any activity in the area of medical device
development, line or staff operations, manufacturing or marketing, including but
not limited to any activity in the area of human resources, which is competitive
with Boston Scientific as it relates to any of the work Employee performed
during his employment or the Consulting Services Period or with which Employee
was familiar as an employee of Boston Scientific or in connection with his
performance of the Consulting Services.

         14.      CONFIDENTIALITY
                  ---------------

                  Employee acknowledges and understands that the terms of this
Agreement will be filed in accordance with the rules and regulations of the
Securities and Exchange Commission and may therefore become publicly available.

         15.      FAILURE TO MEET OBLIGATIONS
                  ---------------------------

                  In the event of a breach of Paragraphs 9(a), 12 or 13 above,
which Employee agrees would cause Boston Scientific irreparable harm, Employee
shall repay to Boston Scientific all of the amounts paid under Paragraphs 2(a),
2(c), 3(b), 3(c) and 11(b) above, and shall be liable, moreover, for any damages

         17.      GOVERNING LAW; SEVERABILITY
                  ---------------------------

                  This Agreement is entered into and shall be construed under
the laws of the Commonwealth of Massachusetts, without regard to its conflict of
laws rules. In the event any provision of this Agreement is determined to be
illegal or unenforceable by a duly authorized court of competent jurisdiction,
then the remainder of this Agreement shall not be affected thereby, it being the
intention of the parties that each provision of this Agreement shall be valid
and enforceable to the fullest extent permitted by law. Except as provided
immediately below, if any portion of the Release language in Paragraph 6, above,
were ruled to be unenforceable for any reason, Employee shall return the
consideration provided under Paragraphs 2(a), 2(c), 3(b), 3(c) and 11(b) above,
to Boston Scientific upon demand by Boston Scientific, which demand shall be
made if Employee were to file any claims against any of the Releasees in
violation of this Agreement, especially Paragraph 7. The foregoing sentence
shall not apply to Employee's ability to bring an ADEA charge or a lawsuit
challenging the waiver of ADEA claims.

         18.      WAIVERS; AMENDMENTS
                  -------------------

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

         19.      NO OTHER INDUCEMENTS
                  --------------------

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

         20.      PERSONS BOUND BY THE AGREEMENT
                  ------------------------------

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

         21.      ASSIGNMENT OF INTERESTS
                  -----------------------

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

         22.      PREVAILING PARTY ENTITLED TO FEES
                  ---------------------------------

                  In the event that any action or proceeding is initiated to
enforce or interpret the provisions of this Agreement, or to recover for a
violation of the Agreement, the prevailing party in any such action or
proceeding shall be entitled to its costs (including reasonable attorneys'
fees); provided that if the Employee files a lawsuit challenging the waiver of
ADEA claims contained herein, the prevailing party will be entitled to its
costs, including reasonable attorneys' fees, only to the extent specifically
authorized under federal law.

         23.      REPRESENTATION
                  --------------

                  Boston Scientific hereby advises Employee to consult an
attorney of his choice before executing this Agreement. Employee represents
that, prior to executing this Agreement, he was advised to and had the
opportunity to review the provisions of this Agreement with counsel of his
