issued is registered in the name of Cede & Co. or such other name as requested
by an authorized representative of The Depository Trust Company and any payment
hereon is made to Cede & Co., ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE
OR OTHERWISE BY A PERSON IS WRONGFUL since the registered owner hereof, Cede &
Co., has an interest herein.

                                   JPMORGAN CHASE BANK, N.A.,
                                   as Trustee

                          [REVERSE OF FORM OF SECURITY]

                          BOSTON SCIENTIFIC CORPORATION

                              6.40 % NOTE DUE 2016

            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 6.40% 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 June
9, 2006 through but excluding the date on which interest is paid. Interest shall
be payable in arrears on June 15 and December 15 of each year (each an "Interest
Payment Date"), commencing December 15, 2006. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

            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 June 1 and December 1 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 and interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts. 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; provided, however, that so long as the Securities are registered in
the name of The Depository Trust Company ("DTC"), or its nominee, all payments
of principal, Redemption Price and interest in respect thereof will be made in
immediately available funds.

            3. Paying Agent and Security Registrar. Initially, JPMorgan Chase
Bank, N.A., will act as Paying Agent and Security Registrar. The Company may
change any Paying Agent or Security Registrar without notice.

            4. Indenture. The Company issued the Securities under an Indenture,
dated as of June 1, 2006 (the "Indenture"), between the Company and JPMorgan
Chase Bank, N.A., 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 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 June 9, 2006 and any additional Securities subsequently
issued shall be treated as a single class for all

<PAGE>

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 are subject to redemption
upon not less than 30 nor more than 60 days notice mailed to the Holder, at any
time prior to maturity as a whole or in part, at the election of the Company at
a 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 (not including any portion of such payments of interest accrued to the
date of redemption) discounted to the Redemption Date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate plus 25 basis points, plus, in each case, accrued and unpaid
interest on the Securities to the Redemption Date.

            "Adjusted Treasury Rate" means, with respect to any Redemption Date,
the rate per year equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such Redemption Date.

            "Comparable Treasury Issue" means the United States Treasury
security selected by a Quotation Agent as having maturity comparable to the
remaining term of the Securities to be redeemed that would be utilized, 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.

            "Quotation Agent" means the Reference Treasury Dealer appointed by
the Trustee after consultation with the Company.

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

            "Reference Treasury Dealer" means (1) Merrill Lynch, Pierce, Fenner
& Smith Incorporated, Banc of America Securities LLC, Bear, Stearns & Co. Inc.,
Deutsche Bank Securities Inc., Wachovia Capital Markets, LLC and their
respective successors; provided, however, that, if any of the foregoing shall
cease to be a primary United States Government securities dealer in the United
States (a "Primary Treasury Dealer"), the Company shall substitute therefor
another Primary Treasury Dealer; and (2) any other Primary Treasury Dealers
selected by the Trustee after consultation with the Company.

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

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

<PAGE>

            7. Denominations, Transfer, Exchange. The Securities are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. 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.

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

            9. 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.

            10. 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.

            11. 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.

            12. 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 shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder. Holders of the Securities may not enforce the
Indenture or the Securities except as provided in the Indenture. The Trustee may
require indemnity reasonably satisfactory to it before it enforces the Indenture
or the Securities. Subject to certain limitations, Holders of a majority in
principal amount of the then Outstanding Securities may direct the Trustee in
its exercise of any trust or power. The Company must furnish an annual
compliance certificate to the Trustee.

<PAGE>

            13. No Recourse Against Others. A director, officer, employee, or
stockholder, as such, of the Company or any of its Affiliates shall not have any
liability for any obligations of the Company under the Securities or the
Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of the Securities by accepting a
Security waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Securities.

            14. Defeasance. The Indenture contains provisions (which provisions
apply to this Security) for defeasance at any time of (a) the entire
indebtedness of the Company in respect of this Security and (b) certain
restrictive covenants and Defaults and Events of Default, in each case upon
compliance by the Company with certain conditions set forth therein.

            15. Authentication. This Security shall not be valid until the
Trustee signs the certificate of authentication to this Security.

            16. GOVERNING LAW. THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

            The Company will furnish to any Holder of Securities upon written
request and without charge a copy of the Indenture. Requests may be made to:

                  First Amendment, dated February 10, 2005, to

                            SECURITYHOLDERS AGREEMENT
                           THL - NORTEK INVESTORS, LLC
                           Dated as of August 27, 2004

      THIS FIRST AMENDMENT, dated as of February 10, 2005 (the "First
Amendment"), amends that certain SECURITYHOLDERS AGREEMENT, dated as of August
27, 2004 (the "Original Agreement"), among THL - Nortek Investors, LLC, a
Delaware limited liability company (the "Company"), Nortek Holdings, Inc., a
Delaware corporation formerly known as THL Buildco Holdings, Inc. ("Holdings"),
Thomas H. Lee Equity Fund V, L.P. and the other THL Investors (as defined in the
Original Agreement), Putnam Investments Employees' Securities Company I LLC,
Putnam Investments Employees' Securities Company II LLC, Putnam Investments
Holdings, LLC, Third Party Investors (as defined therein) and Management
Securityholders (as defined therein). Capitalized terms used and not otherwise
defined in this Amendment are used herein as defined in the Original Agreement.
As used herein, the term "this Agreement" means the Original Agreement, as
amended by this First Amendment.

      WHEREAS, the Securityholders entered into the Original Agreement in August
2004 and the transactions contemplated by the first recital to the Original
Agreement were completed;

      WHEREAS, the Company, Holdings and the Securityholders now want to effect
a recapitalization transaction pursuant to which: (i) the Company will transfer
to NTK Holdings, Inc., a new Delaware corporation ("NTK Holdings") all of the
outstanding shares of Holdings in exchange for the issuance to the Company of
shares of the common stock of NTK Holdings, as a result of which exchange NTK
Holdings will become a wholly-owned subsidiary of the Company and Holdings will
become a wholly-owned subsidiary of NTK Holdings, and (ii) NTK Holdings will
issue and sell certain discount notes, it being contemplated that a portion of
the proceeds from such issuance will be used to pay a dividend to the Company
which, in turn, will make a distribution to its members; and

      WHEREAS, the Securityholders and NTK Holdings believe it to be in their
respective best interests and in the best interests of the Company that they
enter into this Amendment so that the terms of the Original Agreement will
continue (adjusted appropriately to reflect the interposition of NTK Holdings as
a new intermediate holding company) to provide certain rights and restrictions
with respect to the Securities owned by them or their permitted transferees;

      NOW, THEREFORE, in consideration of the mutual covenants and obligations
set forth in this Agreement, the parties hereto agree as follows:
