[REVERSE OF FORM OF SECURITY]


BOSTON SCIENTIFIC CORPORATION


0.625% SENIOR NOTE DUE 2027


1.       Interest.
BOSTON SCIENTIFIC CORPORATION, a Delaware corporation (the “Company”), which definition shall include any successor
thereto in accordance with the Indenture (as defined below), promises to pay, until the principal hereof is paid or made available
for payment, interest on the principal amount set forth on the reverse side hereof at a rate of 0.625% per annum. Interest on the
Securities will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid,
from November 12, 2019 to but excluding the date on which interest is paid. Interest shall be payable in arrears on December 1
of each year (each an “Interest Payment Date”), commencing December 1, 2020. Interest on the Securities will be calculated
on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from
and including the last date on which interest was paid on the Securities (or November 12, 2019 if no interest has been paid on
the Securities), to but excluding the next scheduled Interest Payment Date.


2.       Method
of Payment. The Company will pay interest on the Securities to the Persons who are registered Holders of Securities at the
close of business on the immediately preceding November 15 of each year (each, a “Regular Record Date”). Holders must
surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal, the Redemption Price (pursuant
to paragraph 5 herein), any Change of Control Payment and interest in such coin or currency of the member states of the European
Monetary Union that have adopted or that adopt the single currency in accordance with the treaty establishing the European Community,
as amended by the Treaty on European Union as at the time of payment shall be legal tender for the payment of public and private
debts. If such currency is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond
the Company’s control or if such currency is no longer being used by the then member states of the European Economic and
Monetary Union that have adopted it as their currency or for the settlement of transactions by public institutions of or within
the international banking community, then all payments in respect of the Securities will be made in U.S. dollars until such currency
is again available to the Company or so used. In such a case, amounts payable on any date in such currency will be converted into
U.S. dollars on the basis of the then most recently available market exchange rate for such currency. Any payment in respect of
the Securities so made in U.S. dollars will not constitute an Event of Default under the Securities or the Indenture (as defined
below). At the Company’s option, interest may be paid by check mailed to the registered address of the Holder or by wire
transfer to an account designated by the Holder of this Security.


3.       Paying
Agent and Security Registrar. Initially, Elavon Financial Services DAC (UK Branch) will act as Paying Agent, and U.S. Bank
National Association will act as Security Registrar. The Company may change any Paying Agent or Security Registrar without notice.


    	 	5 	 



     


    

4.       Indenture.
The Company issued the Securities under an Indenture, dated as of May 29, 2013 (the “Indenture”), between the Company
and U.S. Bank National Association, as Trustee (the “Trustee”). This Security is one of an issue of Securities of the
Company issued under the Indenture. The terms of the Securities include those stated herein and in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939, as amended from time to time (the “TIA”). The
Securities are subject to all such terms, and Holders of the Securities are referred to the Indenture and the TIA for a statement
of them. Capitalized terms used herein and not otherwise defined have the meanings set forth in the Indenture. The Securities constitute
senior indebtedness of the Company and, as such, shall be general unsecured and unsubordinated obligations of the Company ranking
equally with all of the Company’s unsecured and unsubordinated obligations. The Company may, subject to the terms of the
Indenture and applicable law, issue additional Securities under the Indenture. The Securities issued on November 12, 2019 and any
additional Securities subsequently issued shall be treated as a single class for all purposes of the Indenture. The Indenture limits
the ability of the Company to incur certain liens and to merge or consolidate with another entity or transfer all or substantially
all of its property and assets.


5.       Optional
Redemption. The Securities will be redeemable at any time prior to September 1, 2027 at the option of the Company, in whole
or in part, on at least 15 days, but no more than 60 days prior written notice mailed to the registered holders of the Securities
(with a copy to the Trustee) to be redeemed, on any date prior to maturity at a redemption price equal to the greater of (i) 100%
of the principal amount of the Securities to be redeemed or (ii) as determined by a Quotation Agent, the sum of the present values
of the remaining scheduled payments of principal and interest thereon to the Par Call Date (not including any portion of such payments
of interest accrued to the date of redemption) discounted to the date of redemption (the “Redemption Date”) on an annual
basis (ACTUAL/ACTUAL(ICMA)) at the Comparable Government Bond Rate (as defined below) plus 20 basis points, plus, in each case,
accrued and unpaid interest on the Securities to, but not including, the Redemption Date (subject to the right of holders as of
the close of business on a regular record date to receive interest due on the related interest payment date). At any time and from
time to time on or after September 1, 2027 (the date that is three months prior to the maturity date of the Securities) (the “Par
Call Date”), the Company may redeem the Securities, in whole or in part, at a redemption price equal to 100% of the principal
amount of the Securities being redeemed plus accrued and unpaid interest to the Redemption Date.


“Comparable Government Bond Rate”
means, with respect to any Redemption Date, the rate per annum equal to the annual equivalent yield to maturity or interpolated
yield to maturity (on a day count basis), computed as the third Business Day immediately preceding that Redemption Date, of the
Comparable Government Issue (as defined below), assuming a price for the Comparable Government Issue (expressed as a percentage
of its principal amount) equal to the Comparable Price (as defined below) for such Redemption Date.


“Comparable Government Issue”
means the euro-denominated security issued by the German federal government selected by a Quotation Agent as having an actual or
interpolated maturity comparable to the remaining term of the Securities to be redeemed that would be utilized (assuming that the
Securities matured on the Par Call Date), at the time of selection and in accordance with customary financial practice, in pricing
new issues of corporate debt securities of comparable maturity to the remaining term of such Securities.


    	 	6 	 



     


    

“Comparable Price” means, with
respect to any Redemption Date, (1) the average of the Reference Dealer Quotations (as defined below) for such Redemption Date,
after excluding the highest and lowest such Reference Dealer Quotations, or (2) if the Trustee obtains fewer than three such Reference
Dealer Quotations, the average of all such quotations.


“Quotation Agent” means the
Reference Dealer appointed by the Trustee after consultation with the Company.


“Reference Dealer” means (1)
each of Barclays Bank PLC, Goldman Sachs & Co. LLC and Merrill Lynch International and their respective successors; provided,
however, that, if any of the foregoing shall cease to be a broker or dealer of, and/or a market maker in, German government bonds
(a “Primary Bond Dealer”), the Company shall substitute therefor another Primary Bond Dealer, and (2) any other Primary
Bond Dealers selected by the Trustee after consultation with the Company.


“Reference Dealer Quotations”
means, with respect to each Reference Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and
ask prices for the Comparable Government Issue (expressed in each case as a percentage of its principal amount) quoted in writing
to the Trustee by such Reference Dealer at 5:00 p.m. London time, on the third Business Day preceding such Redemption Date.


If the Company redeems only some of the
Securities, the Trustee shall determine by lot the Securities to be redeemed or, in the case of Securities held in global form,
pursuant to applicable Depositary procedures.


6.       
Redemption for Tax Reasons. Subject to a period of not less than 15 nor more than 60 days’ prior written notice to
the Holders of the Securities to be redeemed, the Company may redeem the Securities at any time after the issue date and prior
to the maturity date, in whole, but not in part, at a Redemption Price equal to 100% of the aggregate principal amount of Securities
being redeemed, plus accrued and unpaid interest, if any, to (but not including) the Redemption Date, on the date determined by
the Company for early redemption, if:


		A.	as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of a Relevant
Taxing Jurisdiction (as defined below), or any change in, or amendment to, an official position regarding the application or interpretation
of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after November 6, 2019,
the Company becomes or will become obligated to pay Additional Amounts (as defined below); or



		B.	any act is taken by a taxing authority of a Relevant Taxing Jurisdiction on or after November 6, 2019, whether or not such
act is taken with respect to the Company or any of its affiliates, that results in a substantial probability that the Company will
be required to pay Additional Amounts on the Securities; provided in each case that the Company determines, in its business judgment
(determined in good faith), that the obligation to pay the Additional Amounts cannot be avoided by the use of reasonable measures
available to it (including, for the avoidance of doubt, 



    	 	7 	 



     


    
		 	the appointment of a new Paying Agent where this would be reasonable and
would not cause the Company to incur material additional out-of-pocket costs, but not including assignment of the obligation to
make payment with respect to the Securities).





No redemption above may be made unless
(i) the Company shall have received an opinion of independent counsel to the effect that any such change, amendment or act described
in paragraphs (A) or (B) above results in the Company’s requirement to pay (in the case of paragraph (A)) or a substantial
probability that the Company will be required to pay (in the case of paragraph (B)) the Additional Amounts described herein and
(ii) the Company shall have delivered to the Paying Agent a certificate, signed by a duly authorized officer, stating that based
on such opinion, the Company is entitled to redeem the Securities pursuant to their terms.


7.       Additional
Amounts. All payments of principal, premium, if any, and interest by or on behalf of the Company pursuant to the terms of the
Securities shall be made free and clear of, and without deduction or withholding for or on account of, any present or future taxes,
duties, assessments or other governmental charges of whatsoever nature required to be deducted or withheld by the United States,
any state thereof or the District of Columbia, or any other jurisdiction through which payment on the Securities is made, or any
political subdivision or taxing authority therein or thereof (a “Relevant Taxing Jurisdiction”), unless such withholding
or deduction is required by law.


In the event any withholding or deduction
on payments in respect of the Securities for or on account of any present or future tax, assessment or other governmental charge
is required to be deducted or withheld by a Relevant Taxing Jurisdiction, the Company shall remit the full amount required to be
deducted or withheld to the relevant authority in accordance with applicable law and pay such additional amounts (the “Additional
Amounts”) so that every net payment of the principal of, premium, if any, and interest on the Securities will result in receipt
by each Holder of the Securities of such amounts (after all such withholding or deduction, including on any additional amounts)
as would have been received had no such withholding or deduction been required. The Company will not be required, however, to make
any payment of Additional Amounts for or on account of:


		A.	any tax, assessment or other governmental charge that would not have been imposed but for (i) the existence of any present
or former connection (other than a connection arising solely from the ownership of those Securities, the receipt of payments in
respect of those Securities or exercise or enforcement of rights under the Securities) between the Holder of the Securities (or
beneficial owner of the Securities), or between a fiduciary, settlor, beneficiary of, member or shareholder of, or possessor of
a power over, that Holder or beneficial owner (if that Holder or beneficial owner is an estate, trust, partnership or corporation)
and the Relevant Taxing Jurisdiction, including that Holder or beneficial owner, or that fiduciary, settlor, beneficiary, member,
shareholder or possessor, being or having been a citizen or resident or treated as a resident of a Relevant Taxing Jurisdiction
or being or having been engaged in trade or business or present in the Relevant Taxing Jurisdiction or having had a permanent establishment
in the Relevant Taxing Jurisdiction or (ii) the presentation of a Security for payment on a 



    	 	8 	 



     


    
		 	more than 30 days after the later
of the date on which that payment becomes due and payable and the date on which payment is duly provided for;



		B.	any payment to a Holder of the Securities that is not the sole beneficial owner of the Securities, or a portion thereof, or
that is a fiduciary or partnership, but only to the extent that a beneficiary or settlor with respect to the fiduciary, or member
of the partnership or beneficial owner would not have been entitled to the payment of any such Additional Amounts had the beneficiary,
settlor, member or beneficial owner received directly its beneficial or distributive share of the payment;



		C.	any estate, inheritance, gift, sales, transfer, capital gains, excise, personal property, wealth or similar tax, assessment
or other governmental charge;



		D.	any tax, assessment or other governmental charge imposed by reason of the beneficial owner’s or Holder’s past or
present status as a passive foreign investment company, a controlled foreign corporation, a foreign tax exempt organization or
a personal holding company with respect to the United States or as a corporation that accumulates earnings to avoid U.S. federal
income tax;



		E.	any tax, assessment or other governmental charge which is payable otherwise than by withholding or deducting from payment of
principal of or premium, if any, or interest on such Securities;



		F.	any tax, assessment or other governmental charge which would not have been imposed but for the failure of a beneficial owner
or any Holder of Securities to comply (to the extent that it is legally able to do so) with a request to satisfy certification,
information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with
the Relevant Taxing Jurisdiction of the beneficial owner or any Holder of Securities (including, but not limited to, the requirement
to provide Internal Revenue Service Forms W-8BEN, W-8BEN-E, W-8ECI, W-9 or any subsequent versions thereof or successor thereto,
and including, without limitation, any documentation requirement under an applicable income tax treaty);



		G.	any tax, assessment or other governmental charge imposed by the United States, any state thereof or the District of Columbia
(or any political subdivision or taxing authority therein or thereof) on interest received by (1) a 10 percent shareholder (as
defined in Section 871(h)(3)(B) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the regulations
that may be promulgated thereunder) of the Company, or (2) a controlled foreign corporation that is related to the Company within
the meaning of Section 864(d)(4) of the Code, or (3) a bank receiving interest described in Section 881(c)(3)(A) of the Code, to
the extent such tax, assessment or other governmental charge would not have been imposed but for the beneficial owner’s status
as described in subparagraphs (1) through (3) of this paragraph (G);



    	 	9 	 



     


    

		H.	any tax, assessment or other governmental charge required to be withheld or deducted under Sections 1471 through 1474 of the
Code (commonly referred to as “FATCA”), any regulations or other guidance thereunder, or any agreement (including any
intergovernmental agreement) entered into in connection therewith; or any law, regulation or other official guidance enacted in
any jurisdiction implementing FATCA or an intergovernmental agreement in respect of FATCA;



		I.	any tax, assessment or other governmental charge that would not have been imposed but for a change in law, regulation, or administrative
or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever
occurs later; or



		J.	any combination of the above.



8.       Repurchase
at the Option of Holders upon Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs, unless the
Company has exercised its option to redeem the Securities as described under paragraph 5 above or the Company has been required
to redeem the Securities as described under paragraph 6 above, each Holder of the Securities will have the right to require the
Company to purchase all or a portion (equal to €100,000 and any integral multiples of €1,000 in excess thereof) of such
Holder’s Securities pursuant to the offer described below (a “Change of Control Offer”) at a purchase price equal
to 101% of the aggregate principal amount of such Holder’s Securities that are repurchased, plus accrued and unpaid interest,
if any, to, but not including, the date of repurchase (the “Change of Control Payment”), subject to the rights of Holders
of Securities on the relevant record date to receive interest due on the relevant Interest Payment Date.


The Company will be required to send a
notice to each Holder of the Securities by first class mail, with a copy to the Trustee, within 30 days following the date upon
which any Change of Control Repurchase Event occurred, or at the Company’s option, prior to any Change of Control but after
the public announcement of the pending Change of Control. The notice will govern the terms of the Change of Control Offer and will
describe, among other things, the transaction that constitutes or may constitute the Change of Control Repurchase Event and the
purchase date. The purchase date will be at least 30 days but no more than 60 days from the date such notice is mailed, other than
as may be required by law (a “Change of Control Payment Date”). If the notice is mailed prior to the date of consummation
of the Change of Control, the notice will state that the Change of Control Offer is conditioned on the Change of Control being
consummated on or prior to the Change of Control Payment Date.


On the Change of Control Payment Date,
the Company will, to the extent lawful:


		·	accept for payment all properly tendered Securities or portions of Securities not validly withdrawn;



		·	deposit with the Paying Agent the required payment for all properly tendered Securities or portions of Securities not validly
withdrawn; and



    	 	10 	 



     


    

		·	deliver or cause to be delivered to the Trustee the repurchased Securities, accompanied by an officers’ certificate stating,
among other things, the aggregate principal amount of repurchased Securities.



The Company will not be required to make
a Change of Control Offer with respect to the Securities upon the occurrence of a Change of Control Repurchase Event if a third
party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made
by the Company and the third party purchases all Securities properly tendered and not withdrawn under its offer. In addition, the
Company will not repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event
of Default under the Indenture.


The Company will comply with the requirements
of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations
are applicable, in connection with the repurchase of Securities as a result of a Change of Control Repurchase Event. To the extent
that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Securities,
the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under
the Change of Control Offer provisions of the Securities by virtue of any such conflict.


 


For purposes of the foregoing discussion,
the following definitions apply:


“Capital Stock” means
the capital stock of every class whether now or hereafter authorized, regardless of whether such capital stock shall be limited
to a fixed sum or percentage with respect to the rights of the holders thereof to participate in dividends and in the distribution
of assets upon the voluntary or involuntary liquidation, dissolution or winding up of such corporation.


“Change of Control”
means the occurrence of any of the following:


		·	the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation),
in one or more series of related transactions, of all or substantially all of the Company’s assets and the assets of the
Company’s subsidiaries, taken as a whole, to any “person” (as that term is used in Section 13(d)(3) of the Exchange
Act), other than the Company or one of its subsidiaries;



		·	the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that
any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company or one of its subsidiaries,
becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of more than
50% of the Company’s then outstanding Voting Stock or other Voting Stock into which its Voting Stock is reclassified, consolidated,
exchanged or changed, measured by voting power rather than number of shares; or



		·	the adoption of a plan relating to the Company’s liquidation or dissolution.



    	 	 11	 



     


    

Notwithstanding the foregoing, a transaction
will not be considered to be a Change of Control if (a) the Company becomes a direct or indirect wholly-owned subsidiary of a holding
company and (b)(x) immediately following that transaction, the direct or indirect holders of the Voting Stock of the holding company
are substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction or (y) immediately
following that transaction, no person is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of
such holding company.


“Change of Control Repurchase
Event” means the occurrence of both a Change of Control and a Rating Event.


“Fitch” means Fitch,
Inc. and its successors.


“Investment Grade” means
a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s), a rating
of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) and a rating of BBB- or better
by Fitch (or its equivalent under any successor rating categories of Fitch); provided, however, that the Company shall not be required
to maintain a rating by more than two Rating Agencies at any time and if only two Rating Agencies provide a rating with respect
to the Securities, then “Investment Grade” with respect to the Securities shall mean the applicable rating described
above of such two Rating Agencies with respect to the Securities.


“Moody’s” means
Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.


“Rating Agencies” means
each of Moody’s, S&P and Fitch, or if any of Moody’s, S&P or Fitch ceases to rate the Securities or fails to
make a rating of the Securities publicly available, any “nationally recognized statistical rating organization” within
the meaning of Section 3(a)(62) under the Exchange Act that is selected by the Company as a replacement agency for Moody’s,
S&P or Fitch, or each of them, as the case may be; provided, however, that the Company shall not be required to maintain a
rating by more than two Rating Agencies at any time.


“Rating Event” means
the rating of the Securities shall be decreased by each of the Rating Agencies independently by one or more gradations during the
Rating Period (as defined below). If the rating of the Securities by each of the Rating Agencies is Investment Grade, then “Rating
Event” will mean the rating of the Securities shall be decreased by one or more gradations by each Rating Agency so that
the ratings of the Securities by all of the Rating Agencies fall below Investment Grade, on any date from the date of the public
notice of an arrangement that could result in a Change of Control until the end of the 30-day period following public notice of
the occurrence of the Change of Control (the “Rating Period”) (which 30-day period shall be extended by no more than
60 days from the date of the occurrence of the Change of Control if the rating of the Securities is under publicly announced consideration
for possible downgrade by any of the Rating Agencies and each other Rating Agency has either downgraded, or publicly announced
that it is considering downgrading, the Securities). A Rating Event otherwise arising by virtue of a particular reduction in rating
will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a Rating Event for
purposes of the definition of “Change of Control Repurchase Event”) if each Rating Agency 


    	 	12 	 



     


    

making the reduction in rating to which this definition would
otherwise apply does not announce or publicly confirm or inform the Trustee under the Indenture in writing at the Company’s request
that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of,
the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the Rating Event).


“S&P” means S&P
Global Ratings, a division of S&P Global Inc., and its successors.


“Voting Stock” means,
with respect to any specified person as of any date, the Capital Stock of such person that is at the time entitled to vote generally
in the election of the board of directors of such person.


9.       Sinking
Fund. No sinking fund is provided for the Securities.


10.       Denominations,
Transfer, Exchange. The Securities are in registered form without coupons in minimum denominations of €100,000 and integral
multiples of €1,000 in excess thereof. A Holder may transfer or exchange Securities in accordance with the Indenture. No service
charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906, 1107 or 1305 of the Indenture not involving any transfer.


11.       Persons
Deemed Owners. The registered Holder of a Security may be treated as the owner of it for all purposes.


12.       Unclaimed
Money. Subject to any applicable abandoned property laws, if money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled
to the money must look to the Company for payment as unsecured general creditors unless an “abandoned property” law
designates another Person.


13.       Amendment,
Supplement, Waiver. The Company and the Trustee may, without the consent of the Holders of any outstanding Securities, amend,
waive or supplement the Indenture or the Securities for certain specified purposes, including, among other things, curing ambiguities,
defects or inconsistencies, or making any other change that does not adversely affect the rights of any Holder in any material
respect. Other amendments and modifications of the Indenture or the Securities may be made by the Company and the Trustee with
the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Securities affected,
subject to certain exceptions requiring the consent of the Holders of each Security affected thereby.


14.       Successor
Corporation. When a successor corporation assumes all the obligations of its predecessor under the Securities and the Indenture
and the transaction complies with the terms of Article 8 of the Indenture, the predecessor corporation, subject to certain exceptions,
will be released from those obligations.


    	 	 13	 



     


    

15.       Defaults
and Remedies. Events of Default are set forth in the Indenture. Subject to certain limitations in the Indenture, if an Event
of Default (other than an Event of Default specified in Section 501(5) or Section 501(6) of the Indenture) occurs and is continuing,
then the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities may, or the Trustee may, declare
the principal of, plus accrued interest, if any, to be due and payable immediately. If an Event of Default specified in Section
501(5) or Section 501(6) of the Indenture occurs and is continuing, the principal of and accrued interest on all of the Securities
