In the case of Notes represented by physical securities, a new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. In the case of Notes represented by a global Security, the outstanding principal amount of the global Security representing the Notes will be reduced by book-entry. Notes called for redemption become due on the redemption date. On and after the redemption date, interest will cease to accrue on Notes or portions of them called for redemption (unless the Company defaults in the payment of the redemption price and accrued interest). On or before the redemption date, the Company will deposit with a paying agent (or the Trustee) money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on that date.

SECTION 3.3 Notice of Redemption.  (a)  The Company will deliver, not less than 10 but not more than 60 days prior to the redemption date, a notice of redemption to each Holder of Notes (with copy to the Trustee).

SECTION 4.1 Change of Control.  (a)  If a Change of Control Triggering Event occurs with respect to the Notes, unless the Company has exercised its option to redeem the Notes by notifying the Holders of the Notes to such effect, the Company shall be required to make a Change of Control Offer to each Holder of the Notes as to which the Change of Control Triggering Event has occurred to repurchase all or any part (equal to €100,000 or an integral multiple of €1,000 in excess of €100,000) of that Holder’s Notes.  In a Change of Control Offer, the Company shall offer payment in cash equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (a “Change of Control Payment”). Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to €100,000 or an integral multiple of €1,000 in excess thereof) of such Holder’s Notes at an offer price in cash equal to the Change of Control Payment.

(b)          Within 30 days following any Change of Control Triggering Event, or at the Company’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 sent to Holders of the Notes, and a copy of such notice shall be delivered to the Trustee, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the 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 sent (a “Change of Control Payment Date”).  The notice shall, if sent prior to the date of consummation of the Change of Control state that the Change of Control Offer is conditioned on the Change of Control Triggering Event with respect to the Notes occurring on or prior to the Change of Control Payment Date.  The notice shall state, among other things:

A Change of Control Offer may be made at the same time as consents are solicited with respect to an amendment, supplement or waiver of the provisions of this Supplemental Indenture, the Notes and/or the Guarantees; provided that such Change of Control Offer shall not include the delivery of such consents as a condition precedent.

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 the Notes but in that event the principal amount of the Notes remaining outstanding after repurchase must be equal to €100,000 or an integral multiple of €1,000 in excess thereof.  The Notes which are repurchased only in part (pursuant to the provisions of this Section 4.1) shall be so stated in the applicable “Option to Elect Repayment Form,” and, with respect to Notes represented by physical securities, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of the Notes without service charge, a new Note or Notes of the same series and tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Notes.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of €100,000 or an integral multiple of €1,000 in excess of €100,000. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

This Security may be exchanged in whole but not in part (free of charge) for definitive registered Securities (“Definitive Notes”) of like tenor in minimum denominations of €100,000 principal amount and integral multiples of €1,000 in excess thereof only upon (i) the occurrence of an Exchange Event or (ii) an event of default with respect to the Securities will have occurred and be continuing. An “Exchange Event” shall occur if Euroclear or Clearstream notifies the Company that it is unwilling or unable to continue to act as depositary and a successor depositary is not appointed by the Company within 90 days. The Company will promptly give notice to Holders in accordance with the Indenture upon the occurrence of an Exchange Event. In the event of the occurrence of any Exchange Event, Euroclear and/or Clearstream or any person acting on their behalf, acting on the instructions of any holder of an interest in this Security, may give written notice to the Security Registrar requesting exchange. Any exchange shall occur no later than 10 days after the date of receipt of the relevant notice by the Security Registrar. Exchanges will be made upon presentation of this Security at the office of the Security Registrar at 2-4 r. Eugène Ruppert, 2453 Luxemburg, Luxembourg by the holder of it on any day (other than a Saturday or Sunday) on which banks are open for general business in Luxembourg. The aggregate principal amount of Definitive Notes issued upon an exchange of this Security will be equal to the aggregate principal amount of this Security. On an exchange in whole of this Security, this Security shall be surrendered to the Security Registrar for cancellation. On any exchange or transfer following which either (i) Notes represented by this Security are no longer to be so represented or (ii) details of the transfer of Notes not so represented shall be entered by the Security Registrar in the Security Register, the principal amount of this Security shall be increased or reduced (as the case may be) by the principal amount so transferred. Until the exchange of the whole of this Security, the registered holder of this Security shall in all respects (except as otherwise provided in this Security) be entitled to the same benefits as if such person were the registered holder of the Definitive Notes represented by this Security.

All notices to the Holders will be valid if mailed to them at their respective address in the register of holders maintained in relation to the Notes or given in accordance with the procedures of Euroclear and Clearstream.

Ownership of interests in this Security (the “Book-Entry Interests”) are limited to persons that have accounts (participants) with a Clearing Agency or persons that hold interests through such participants. The Clearing Agency hold interests in this Security on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries. Except under the limited circumstances set forth above, Book-Entry Interests will not be held in definitive certificated form.

In the event this Security (or any portion hereof) is redeemed, Euroclear and/or Clearstream, as applicable, will redeem an equal amount of the Book-Entry Interests in this Security from the amount received by it in respect of the redemption of this Security. The redemption price payable in connection with the redemption of such Book-Entry Interests will be equal to the amount received by Euroclear and Clearstream, as applicable, in connection with the redemption of this Security (or any portion hereof).

If fewer than all of the Notes are to be redeemed at any time, Euroclear and Clearstream will credit their respective participants’ accounts on a proportionate basis (with adjustments to prevent fractions), by either a pool factor or a reduction in principal amount, at their discretion, or on such other basis as they deem fair and appropriate under the existing practices of Euroclear and Clearstream; provided, however, that no Book-Entry Interest of €100,000 principal amount or less may be redeemed in part.

So long as the Notes are held in global form by the Common Safekeeper, participants must rely on the procedures of Euroclear and/or Clearstream and indirect participants must rely on the procedures of Euroclear, Clearstream and the participants through which they own Book-Entry Interests, to transfer their interests or to exercise any rights of holders under the Notes and/or the Indenture.

None of the Company, the Guarantors, the Security Registrar, the Trustee or the Paying Agent has any responsibility, nor are they liable, for any aspect of the records relating to the Book-Entry Interests.

In the event this Security (or any portion hereof) is redeemed, Euroclear and/or Clearstream, as applicable, will redeem an equal amount of the Book-Entry Interests in this Security from the amount received by it in respect of the redemption of this Security. The redemption price payable in connection with the redemption of such Book-Entry Interests will be equal to the amount received by Euroclear and Clearstream, as applicable, in connection with the redemption of this Security (or any portion hereof). If fewer than all of the Notes are to be redeemed at any time, Euroclear and Clearstream will credit their respective participants’ accounts on a proportionate basis (with adjustments to prevent fractions), by either a pool factor or a reduction in principal amount, at their discretion, or on such other basis as they deem fair and appropriate under the existing practices of Euroclear and Clearstream; provided, however, that no Book-Entry Interest of €100,000 principal amount or less may be redeemed in part.

This certifies that the person whose name is entered in the Security Register is registered as the Holder of the aggregate nominal amount of €500,000,000 of the Notes, being all the Notes represented by this Security.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

THIS SECURITY WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
