                                       4

    SECTION 2.4  PRINCIPAL PAYMENT DATE.  Subject to the provisions of
Section 2.7 hereof and Articles Four and Twelve of the Indenture, the principal
of the Notes shall be become due and payable in a single installment on
September 5, 2000.

    SECTION 2.5  INTEREST AND INTEREST RATES.  Interest on the Notes shall be
payable quarterly on March 5, June 5, September 5 and December 5 of each year,
beginning December 5, 1999 (each, a "FLOATING RATE INTEREST PAYMENT DATE");
PROVIDED, HOWEVER, that if a Floating Rate Interest Payment Date would otherwise
be a day that is not a Business Day, such Floating Rate Interest Payment Date
shall be the next succeeding Business Day, and no additional interest shall be
paid in respect of such intervening period.

    The per annum rate of interest for each Floating Rate Interest Period will
be (1) LIBOR on the second London Business Day preceding the Interest Reset Date
for such Floating Rate Interest Period, referred to as the "Interest
Determination Date", plus (2) .60%. The Company will determine LIBOR for each
Floating Rate Interest Period in accordance with the following provisions:

        (i) On each Interest Determination Date, the Company will ascertain the
    offered rate for three-month deposits in U.S. dollars in the London
    interbank market, which appears on the Telerate Page 3750 as of 11:00 a.m.
    (London time) on such Interest Determination Date.

        (ii) If such rate does not appear on the Telerate Page 3750 or the
    Telerate Page 3750 is unavailable, the Company will request four major banks
    in the London interbank market, referred to as the "Reference Banks" to
    provide the Company with their offered quotation, expressed as a rate per
    annum for three-month deposits in U.S. dollars to leading banks in the
    London interbank market, in a principal amount equal to an amount of not
    less than $1 million that is representative for a single transaction in such
    market at such time, at approximately 11:00 a.m. (London time) on the
    Interest Determination Date. If at least two such quotations are provided,
    LIBOR in respect of that interest determination date will be the arithmetic
    mean of such quotations.

        (iii) If less than two of the Reference Banks provide the Company with
    such offered quotations, LIBOR in respect of that Interest Determination
    Date will be the arithmetic mean of the rates quoted by three major banks in
    The City of New York selected by the Company at approximately 11:00 a.m.,
    New York City time, on that Interest Determination Date for three-month
    loans in U.S. dollars to leading European banks, in a principal amount equal
    to an amount of not less than $1 million that is representative for a single
    transaction in such market at such time; provided, however, that if the
    banks the Company so selected are not quoting as mentioned in this sentence,
    LIBOR will be LIBOR in effect on such Interest Determination Date.

    The interest payable on each Floating Rate Interest Payment Date shall be
the amount of interest accrued from August 31, 1999 or from the most recent
Floating Rate Interest Payment Date to which interest has been paid or duly
provided for, as the case may be, until the principal amount of the Notes has
been paid or duly provided for. Interest on the Notes will be calculated on the
basis of the actual number of days in the applicable Floating Rate Interest
Period divided by 360.

    The interest payable on any Note which is punctually paid or duly provided
for on any Floating Rate Interest Payment Date shall be paid to the Person in
whose name such Note is registered at the close of business on February 18,
May 21, August 21 and November 20 (in each case, whether or not a Business Day),
respectively, immediately preceding such Floating Rate Interest Payment Date
(each, a "Regular Record Date"). Interest payable on any Note which is not
punctually paid or duly provided for on any Floating Rate Interest Payment Date
therefor shall forthwith cease to be payable to the Person in whose name such
Note is registered at the close of business on the Regular Record Date
immediately preceding such Floating Rate Interest Payment Date, and such
interest shall instead be paid to the Person in whose name such Note is
registered at the close of business on the record date established for such
payment by notice by or on behalf of the Company to the Holders of the Notes
mailed by first-class mail not less than

                                       5

15 days prior to such record date to their last addresses as they shall appear
upon the Security register, such record date to be not less than five days
preceding the date of payment of such defaulted interest.

    SECTION 2.6  PLACE OF PAYMENT.  The place of payment where the Notes may be
presented or surrendered for payment, where the principal of and interest and
any other payments due on the Notes are payable, where the Notes may be
surrendered for registration of transfer or exchange and where notices and
demands to and upon the Company in respect of the Notes and the Indenture may be
served shall be in the Borough of Manhattan, The City of New York, and the
office or agency maintained by the Company for such purpose shall initially be
the Corporate Trust Office of the Trustee.

    At the option of the Company, interest on the Notes may be paid (i) by check
mailed to the address of the Person entitled thereto as such address shall
appear in the register of Holders of the Notes or (ii) at the expense of the
Company, by wire transfer to an account maintained by the Person entitled
thereto as specified in writing to the Trustee by such Person by the applicable
record date.

    SECTION 2.7 (a)  ADDITIONAL AMOUNTS; CERTAIN TAX PROVISIONS.  For purposes
of the Notes, Sections 12.1 and 12.2 of the Indenture are amended in their
entirety to read as follows:

        "SECTION 12.1   REDEMPTION UPON CHANGES IN WITHHOLDING TAXES.  The Notes
    may be redeemed, as a whole but not in part, at the election of the Company,
    upon not less than 30 nor more than 60 days notice (which notice shall be
    irrevocable), at a redemption price equal to 100% of the principal amount
    thereof, together with accrued interest, if any, to the redemption date and
    Additional Amounts (as defined in Section 12.2), if any, if as a result of
    any amendment to, or change in, the laws or regulations of Luxembourg or
    Bermuda or any political subdivision or taxing authority thereof or therein
    having power to tax (a "Taxing Authority"), or any change in the application
    or official interpretation of such laws or regulations which amendment or
    change is announced and becomes effective after the date the Notes are
    issued, the Company or Tyco has become or will become obligated to pay
    Additional Amounts, on the next date on which any amount would be payable
    with respect to the Notes, and such obligation cannot be avoided by the use
    of reasonable measures available to the Company or Tyco, as the case may be;
    PROVIDED, HOWEVER, that (a) no such notice of redemption may be given
    earlier than 60 days prior to the earliest date on which the Company or
    Tyco, as the case may be, would be obligated to pay such Additional Amounts,
    and (b) at the time such notice of redemption is given, such obligation to
    pay such Additional Amounts remains in effect. Prior to the giving of any
    notice of redemption described in this paragraph, the Company shall deliver
    to the Trustee (i)(I) a certificate signed by two directors of the Company
    stating that the obligation to pay Additional Amounts cannot be avoided by
    the Company taking reasonable measures available to it or (II) a certificate
    signed by two executive officers of Tyco stating that the obligation to pay
    Additional Amounts cannot be avoided by Tyco taking reasonable measures
    available to it, as the case may be, and (ii) a written opinion of
    independent legal counsel to the Company or Tyco, as the case may be, of
    recognized standing to the effect that the Company or Tyco, as the case may
    be, has or will become obligated to pay Additional Amounts as a result of a
    change, amendment, official interpretation or application described above
    and that the Company or Tyco, as the case may be, cannot avoid the payment
    of such Additional Amounts by taking reasonable measures available to it.

        SECTION 12.2  PAYMENT OF ADDITIONAL AMOUNTS.  All payments made by the
    Company, Tyco and any other Guarantor under or with respect to the Notes and
    the Guarantees will be made free and clear of and without withholding or
    deduction for or on account of any present or future taxes, duties, levies,
    imposts, assessments or governmental charges of whatever nature imposed or
    levied by or on behalf of any Taxing Authority ("Taxes"), unless the
    Company, Tyco or such Guarantor, as the case may be, is required to withhold
    or deduct Taxes by law or by the interpretation or administration thereof.
    In the event that the Company, Tyco or such Guarantor is required to so
    withhold or deduct any amount for or on account of any Taxes from any
    payment made under or with respect to the Notes or the Guarantees, as the
    case may be, the Company, Tyco or such Guarantor, as the case may be, will

                                       6

    pay such additional amounts ("Additional Amounts") as may be necessary so
    that the net amount received by each Holder of Notes (including Additional
    Amounts) after such withholding or deduction will equal the amount that such
    Holder would have received if such Taxes had not been required to be
    withheld or deducted; PROVIDED that no Additional Amounts will be payable
    with respect to a payment made to a Holder of Notes to the extent:

        (a) that any such Taxes would not have been so imposed but for the
    existence of any present or former connection between such Holder and the
    Taxing Authority imposing such Taxes (other than the mere receipt of such
    payment, acquisition, ownership or disposition of such Notes or the exercise
    or enforcement of rights under such Notes, the Guarantees or the Indenture);

        (b) of any estate, inheritance, gift, sales, transfer, or personal
    property Tax imposed with respect to such Notes, except as otherwise
    provided herein;

        (c) that any such Taxes would not have been so imposed but for the
    presentation of such Notes or Guarantees (where presentation is required)
    for payment on a date more than 30 days after the date on which such payment
    became due and payable or the date on which payment thereof is duly provided
    for, whichever is later, except to the extent that the beneficiary or Holder
    thereof would have been entitled to Additional Amounts had the Notes or
    Guarantees been presented for payment on any date during such 30-day period;
    or

        (d) that such Holder would not be liable or subject to such withholding
    or deduction of Taxes but for the failure to make a valid declaration of
    non-residence or other similar claim for exemption, if (x) the making of
    such declaration or claim is required or imposed by statute, treaty,
    regulation, ruling or administrative practice of the relevant Taxing
    Authority as a precondition to an exemption from, or reduction in, the
    relevant Taxes, and (y) at least 60 days prior to the first payment date
    with respect to which the Company, Tyco or such Guarantor shall apply this
    clause (d), the Company, Tyco or such Guarantor shall have notified all
    Holders of Notes in writing that they shall be required to provide such
    declaration or claim.

        The Company, Tyco or such Guarantor, as the case may be, will also
    (i) make such withholding or deduction of Taxes and (ii) remit the full
    amount of Taxes so deducted or withheld to the relevant Taxing Authority in
    accordance with all applicable laws. The Company, Tyco or such Guarantor, as
    the case may be, will use its reasonable best efforts to obtain certified
    copies of tax receipts evidencing the payment of any Taxes so deducted or
    withheld from each Taxing Authority imposing such Taxes. The Company, Tyco
    or such Guarantor, as the case may be, will, upon request, make available to
    the Holders of the Notes, within 60 days after the date the payment of any
    Taxes so deducted or withheld is due pursuant to applicable law, certified
    copies of tax receipts evidencing such payment by the Company, Tyco or such
    Guarantor or if, notwithstanding the Company's, Tyco's or such Guarantor's
    efforts to obtain such receipts, the same are not obtainable, other evidence
    of such payments by the Company, Tyco or such Guarantor.

        At least 30 days prior to each date on which any payment under or with
    respect to the Notes or Guarantees is due and payable, if the Company, Tyco
    or such Guarantor will be obligated to pay Additional Amounts with respect
    to such payment, the Company, Tyco or such Guarantor will deliver to the
    Trustee an Officers' Certificate stating the fact that such Additional
    Amounts will be payable, the amounts so payable and will set forth such
    other information as is necessary to enable such Trustee to pay such
    Additional Amounts to Holders of Notes on the payment date.

        In addition, the Company, Tyco or such Guarantor, as the case may be,
    will pay any stamp, issue, registration, documentary or other similar taxes
    and duties, including interest, penalties and Additional Amounts with
    respect thereto, payable in Luxembourg, Bermuda or the United States or any
    political subdivision or taxing authority of or in the foregoing in respect
    of the creation, issue, offering, enforcement, redemption or retirement of
    the Notes or the Guarantees.

                                       7

        The foregoing provisions shall survive any termination of the discharge
    of the Indenture and shall apply mutatis mutandis to any jurisdiction in
    which any successor Person to the Company, Tyco or such Guarantor, as the
    case may be, is organized or is engaged in business for tax purposes or any
    political subdivisions or taxing authority or agency thereof or therein;
    PROVIDED, HOWEVER, the date on which such Person becomes a successor to the
    Company, Tyco or such Guarantor, as the case may be, shall be substituted
    for the date on which the series of Notes was issued.

        Whenever in the Indenture, the Notes or the Guarantees there is
    mentioned, in any context, the payment of principal (and premium, if any),
    redemption price, interest or any other amount payable under or with respect
    to any Notes or Guarantees, such mention shall be deemed to include mention
    of the payment of Additional Amounts to the extent that, in such context,
    Additional Amounts are, were or would be payable in respect thereof."

    (b) NO SINKING FUND.

    The Company shall have no obligation to redeem or purchase the Notes
pursuant to any sinking fund or analogous provisions or upon the happening of
any specified event or at the option of any Holder of the Notes.

    SECTION 2.8  CURRENCY.  Principal and interest on the Notes shall be payable
in United States dollars.

a nominee of the Depositary, by a nominee of the Depositary to the Depositary or
to another nominee of the Depositary, or by the Depositary or any such nominee
to a successor Depositary or a nominee of such successor Depositary. All Global
Notes will be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary that it is unwilling or
unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 90 days after the date of such
notice from the Depositary; or (ii) the Company in its sole discretion
determines that the Global Notes (in whole but not in part) should be exchanged
for Definitive Notes and delivers a written notice to such effect to the
Trustee; provided that in no event shall the Regulation S Global Note be
exchanged by the Company for Definitive Notes prior to the expiration of the
