The Notes may be redeemed, as a whole but not in part, at the election of the Company and Tyco, 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 January 12, 1999, the Company and Tyco have 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 and Tyco; 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 and Tyco 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 and Tyco shall deliver to the Trustee (i) an Officers’ Certificate from each of the Company and Tyco stating that the obligation to pay Additional Amounts cannot be avoided by the Company and Tyco taking reasonable measures available to it and (ii) a written opinion of independent legal counsel to each of the Company and Tyco (of recognized standing) to the effect that the Company and Tyco have 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 and Tyco cannot avoid the payment of such Additional Amounts by taking reasonable measures available to them.

“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”),

6

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 and Tyco or such Guarantor, as the case may be, will 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 Taxes 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 and Tyco or such Guarantor shall apply this clause (d), the Company and 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 and 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 and Tyco or such Guarantor, as the case may be, will use their or 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 and Tyco’s or such Guarantor’s

7

efforts to obtain such receipts, the same are not obtainable, other evidence of such payments by the Company and 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 and Tyco or such Guarantor will be obligated to pay Additional Amounts with respect to such payment, the Company and 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 setting 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 and 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.

The foregoing provisions shall survive any termination of or 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.

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.”

(2)                                 Restricted Definitive Notes to Unrestricted Definitive Notes.

SECTION 2.13             CHANGE OF CONTROL.

(a)                                 If a Change of Control Triggering Event occurs, unless the Company and Tyco have exercised their option to redeem the Notes, they shall be required to make an offer (a “Change of Control Offer”) to each Holder of the Notes to repurchase, at the Holder’s election, all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth herein. In a Change of Control Offer, the Company and Tyco shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company’s or Tyco’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be mailed to Holders of the Notes describing in reasonable detail the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (a “Change of Control Payment Date”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

(b)                                In order to accept the Change of Control Offer, the Holder must deliver (or otherwise comply with alternative instructions in accordance with the procedures of the Depositary) to the paying agent, at least five Business Days prior to the Change of Control Payment Date, its Note together with the form entitled “Election Form” (which form is annexed hereto as Exhibit D) duly completed, or a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the Financial Industry Regulatory Authority, Inc. or a commercial bank or trust company in the United States setting forth:

(i)                                    the name of the Holder of such Note;

(ii)                                the principal amount of such Note;

(iii)                             the principal amount of such Note to be repurchased;

(iv)                             the certificate number or a description of the tenor and terms of such Note;

(v)                                a statement that the Holder is accepting the Change of Control Offer; and

14

(vi)                             a guarantee that such Note, together with the form entitled “Election Form” duly completed, will be received by the paying agent at least five Business Days prior to the Change of Control Payment Date.

(c)                                 Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be accepted for less than the entire principal amount of a Note, but in that event the principal amount of such Note remaining outstanding after repurchase must equal an integral multiple of $1,000.

(d)                                On the Change of Control Payment Date, the Company and Tyco shall, to the extent lawful:

(i)                                    accept for payment all Notes or portions of such Notes properly tendered pursuant to the Change of Control Offer;

(ii)                                deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(iii)                             deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

(e)                                 The Company and Tyco shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by them and the third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the Company and Tyco shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

(f)                                   The Company and Tyco shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (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 the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with this Section 2.13, the Company and Tyco shall comply with those securities laws and regulations and shall not be deemed to have breached their obligations under this Section 2.13 by virtue of any compliance with such laws or regulations.
