The Series 2024 Notes shall mature on July 16, 2024 and the Series 2029 Notes shall mature on July 16, 2029.

The Series 2024 Notes shall bear interest at a rate of 3.600% per annum, from the issue date of such series of Notes or from the most recent Interest Payment Date to which interest has been paid, as the case may be, payable semi-annually in arrears on each January 16 and July 16, commencing on January 16, 2020 (each an “Interest Payment Date”) until the principal thereof is paid or duly provided for.

Each payment of principal (and premium, if any) and interest (if any) on the Notes will be made to the Persons who are registered Holders of the Notes on the Regular Record Date. Payments due on a date other than a Business Day shall be made on the next succeeding Business Day and such extension of time will not result in a default under the Notes or the Base Indenture or this Third Supplemental Indenture, and no interest will accrue on the postponed amount from the original due date to the next day that is a Business Day.

Subject to the provisions of Section 10.02 of the Base Indenture (i) the principal of (and premium, if any) and interest (if any) on the Notes will be payable at the Place of Payment, (ii) the Notes may be surrendered at the Place of Payment for registration of transfer, (iii) the Notes may be surrendered at the Place of Payment for exchange and (iv) notices and demands to or upon the Company in respect of the Notes may be served at ArcelorMittal USA Holdings II LLC, ▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇.

Section 2.2 Forms Generally.

The Series 2024 Notes and the Series 2029 Notes shall be in substantially the form set forth in Exhibit A and Exhibit B to this Third Supplemental Indenture, respectively.

The Notes are exchangeable for notes registered in the name of a Person other than the Depository or its nominee only in the limited circumstances set forth in Section 3.05 of the Base Indenture.

Sections 4.01, 4.02 and 4.03 of the Base Indenture apply to the Notes.

ARTICLE III - REDEMPTION OF NOTES

Section 3.1 Redemption at the Option of the Company.

The Company will have the right to redeem the Notes of any series, in whole at any time, or in part from time to time, at the Company’s option, on at least 30 days’ but no more than 60 days’ prior notice given to the registered Holders of such series of Notes to be redeemed. The Company will provide notice of such redemption to the Trustee and Securities Administrator in accordance with Section 3.3 of this Third Supplemental Indenture. Upon redemption of the

Notes, the Company will pay a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments (as defined above) of the Notes to be redeemed, discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus the Additional Basis Points for such series of Notes, in each case plus accrued and unpaid interest thereon up to but excluding the Redemption Date.

The Company shall perform and have full responsibility for the calculation of the redemption price and the remaining scheduled payments and neither the Trustee nor the Securities Administrator shall have any responsibility or liability in connection with such calculation or any verification obligation in connection therewith, it being understood that the Trustee or the Securities Administrator shall promptly notify the Company in case of a manifest error in the calculation made by the Company of which a Responsible Officer of the Trustee or the Securities Administrator, as applicable, has actual knowledge. This calculation shall be final and binding absent a manifest error.

The notice of redemption will comply with the provisions of Sections 1.06 and 11.07 of the Base Indenture and will state any conditions applicable to a redemption and the amount of Notes to be redeemed. The Company will comply with the provisions of Section 3.3 of this Third Supplemental Indenture, and, in accordance with Section 1.02 of the Base Indenture, no additional certificate or opinion need be furnished to the Trustee and Securities Administrator with respect to the redemption pursuant to this Section 3.1. For the avoidance of doubt, the Trustee and Securities Administrator will be entitled to fully rely on the Third Supplemental Indenture Section 3.3 Officer’s Certificate confirming the authorization of such redemption without any obligation to verify or otherwise confirm the content thereof and with no liability therefor.

If less than all the Notes are to be redeemed, DTC will select the Notes to be redeemed in accordance with its standard procedures in the case of Notes represented by Global Notes and otherwise by a pro rata basis, by lot or by such other method as the Securities Administrator deems fair and appropriate. Any Notes that are redeemed pursuant to this Section 3.1 will be cancelled.

In accordance with Section 11.03 of the Base Indenture, except as described under this Section 3.1 or Section 3.2 of this Third Supplemental Indenture, the Notes will not otherwise be redeemable by the Company at the Company’s option prior to the Stated Maturity.

Section 3.2 Redemption for Taxation Reasons.

The Notes of any series may be redeemed, at the Company’s option, in whole but not in part, upon giving not less than 30 days’ nor more than 60 days’ notice to the Holders (which notice will be irrevocable) in accordance with Sections 1.06 and 11.07 of the Base Indenture, at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest (including any Additional Amounts), if any, up to but excluding the date fixed by the Company for redemption (the “Tax Redemption Date”) if, as a result of:

(a)

any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of a Relevant Jurisdiction affecting taxation; or

(b)

any change in, or amendment to, an official position regarding the application or written interpretation of such laws, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction),

which change or amendment becomes effective or, in the case of an official position, is announced (i) in the case of the Company, on or after the Closing Date or (ii) in the case of any successor entity, on or after the date such successor entity becomes obligated under the Notes or the Indenture, with respect to any payment due or to become due under the Notes or the Indenture, the Company or its successor entity, as the case may be, is, or on the next Interest Payment Date would be, required to pay Additional Amounts, and such requirement cannot be avoided by the Company or its successor entity, as the case may be, taking reasonable measures available to it (including, for the avoidance of doubt, the appointment of a new paying agent where this would be reasonable); provided that for the avoidance of doubt changing the jurisdiction of the Company or any successor entity is not a reasonable measure for the purposes of this section; and provided, further that no such notice of redemption will be given earlier than 60 days prior to the earliest date on which the Company, or any successor entity, as the case may be, would be obligated to pay such Additional Amounts if a payment in respect of the Notes were then due.

Prior to the giving of any notice of redemption of the Notes of any series pursuant to the foregoing, the Company or its successor entity, as the case may be, will deliver to the Trustee and the Securities Administrator:

(1) an Officer’s Certificate stating that such change or amendment referred to in the prior paragraph has occurred, and describing the facts related thereto and stating that such requirement cannot be avoided by the Company or its successor entity, as the case may be, taking reasonable measures available to it; and

(2) an Opinion of Counsel of recognized standing with respect to tax stating that the requirement to pay such Additional Amounts results from such change or amendment referred to in the prior paragraph.

The Trustee and the Securities Administrator will accept and shall be fully protected in relying upon such Officer’s Certificate and Opinion of Counsel as sufficient evidence of the satisfaction of the conditions precedent described above, in which event it will be conclusive and binding on the Holders.

Any Notes that are redeemed pursuant to this Section 3.2 will be cancelled.

Section 3.3 Election to Redeem; Notice to Trustee and the Securities Administrator.

With respect to the Notes, Section 11.02 of the Base Indenture is hereby deleted in its entirety and replaced with the following:

The due authorization of the election of the Company to redeem any Securities shall be evidenced by an Officer’s Certificate. In case of any redemption at the election of the Company of less than all the Notes, the Company shall provide the Trustee and Securities Administrator

with an Officer’s Certificate stating that no defaults in the payment of interest or Events of Default with respect to the Notes have occurred (which have not been waived or cured). In the case of any redemption of Notes pursuant to an election of the Company which is subject to a condition or computation specified in the terms of such Securities, the Company shall furnish the Trustee and the Securities Administrator with an Officer’s Certificate evidencing compliance with such condition or computation.

Unless otherwise agreed among the Company, Trustee and Securities Administrator, the Company will send the Trustee and Securities Administrator a draft of the Officer’s Certificate evidencing the due authorization of the Company’s election to redeem the Notes and a draft of the notice of redemption to be provided to Holders no later than noon (New York time) on the third Business Day preceding the date on which notice to the Holders of such redemption is to be provided, and the final, signed version of such certificate and the final notice to be sent to Holders shall be provided by the Company to the Trustee and Securities Administrator no later than noon (New York time) on the Business Day preceding the date on which notice to the Holders will be provided and will be held in escrow by the Trustee and Securities Administrator until the date on which notice to the Holders is to be sent. For the avoidance of doubt, the Trustee and Securities Administrator will be entitled to fully rely on any such Officer’s Certificate without any obligation to verify or otherwise confirm the content thereof and with no liability therefor.

In the event that any election by the Company necessitates the retention of any agent by either of the Trustee or the Securities Administrator, the Company agrees that such retention shall be at the sole expense of the Company, subject to the Company’s prior approval of such agent.

ARTICLE IV - OFFER TO PURCHASE UPON A CHANGE OF CONTROL

Section 4.1 Offer To Purchase upon a Change of Control.

Pursuant to Section 10.12 of the Base Indenture, upon the occurrence of a Change of Control, unless the Company has exercised its right to redeem the Notes of any series under Section 3.1 or under Section 3.2, or unless the Change of Control Payment Date would fall on or after the maturity date of the Notes of such series, the Company will make an offer to purchase all or a portion of each Holder’s Notes of such series for which the applicability of this Section 4.1 has been specified pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount tendered plus accrued and unpaid interest, if any, up to but excluding the date of purchase.

Within 30 days following the date upon which the Change of Control 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 Company will deliver, by first class mail (or while the Notes are in global form such notice shall be sent electronically through the Applicable Procedures of the Depositary), a notice to each Holder of Notes at such ▇▇▇▇▇▇’s address as it appears in the Security Register, with a copy to the Trustee and the Securities Administrator, which notice will govern the terms of the Change of Control Offer. Such notice will state the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is delivered,

other than as may be required by law (the “Change of Control Payment Date”). The notice, if delivered prior to the date of consummation of the Change of Control, 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. Holders of Notes electing to have Notes purchased pursuant to a Change of Control Offer will be required to tender the Notes in accordance with the terms of the Change of Control Offer prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

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

(a)

accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;

(b)

deposit with the Paying Agent and instruct the Paying Agent in writing to pay an amount equal to the purchase price in respect of all Notes or portions thereof so tendered; and

(c)

deliver or cause to be delivered to the Securities Administrator with a copy to the Trustee the Notes so accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company.

Upon deposit of the amount of the purchase price and the receipt of the written instructions of the Company specified above, the Paying Agent will promptly mail or wire to each Holder of Notes so tendered the purchase price for such Notes, and the Securities Administrator, upon instruction by the Company and in accordance with the Indenture, will promptly authenticate and mail or cause to be transferred by book entry to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new note will be in a principal amount of at least $2,000 and integral multiples of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The Company shall 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 the Notes as a result of a Change of Control. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached the Company’s obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

The Trustee and the Securities Administrator are under no obligation to ascertain whether a Change of Control or any event that could lead to the occurrence of or could constitute a Change of Control has occurred, and until a responsible officer of the Trustee or the Securities Administrator, as applicable, has actual knowledge or express notice to the contrary, the Trustee and the Securities Administrator may conclusively assume that no Change of Control or other such event has occurred.

ARTICLE V - PAYMENT OF ADDITIONAL AMOUNTS

Section 5.1 Payment of Additional Amounts.

The Company will make all payments of principal of, and premium (if any) and interest on, the Notes of any series without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or within Luxembourg, any jurisdiction in which ArcelorMittal is resident for tax purposes or, in the case of a successor entity, any jurisdiction in which such successor entity is organized or resident for tax purposes (or any political subdivision or taxing authority thereof or therein) (each, as applicable, a “Relevant Jurisdiction”), unless such withholding or deduction is required by law or by regulation or governmental policy having the force of law. In the event that any such withholding or deduction is so required, the Company or any successor entity, as the case may be, will make such deduction or withholding, make payment of the amount so withheld to the appropriate governmental authority and will pay such additional amounts (“Additional Amounts”) that will result in the receipt by the Holders of such amounts that would have been received by such Holders had no such withholding or deduction been required by the Relevant Jurisdiction, except that no Additional Amounts will be payable:

(a)

for or on account of:

(i)

any tax, duty, assessment or other governmental charge that would not have been imposed but for:

(A).

the existence of any present or former connection between the Holder or beneficial owner of such Note, as the case may be, and the Relevant Jurisdiction including, without limitation, such Holder or beneficial owner being or having been a citizen or resident of such Relevant Jurisdiction or treated as a resident thereof or being or having been physically present or engaged in a trade or business therein or having or having had a permanent establishment therein, other than merely holding such Note or the receipt of payments thereunder;

(B).

the presentation of such Note (where presentation is required) more than 30 days after the later of the date on which the payment of the principal of, or premium (if any) or interest on, such Note became due and payable pursuant to the terms thereof or was made or duly provided for, except to the extent that the Holder thereof would have been entitled to such Additional Amounts if it had presented such Note for payment on any date within such 30-day period;

3.600% Notes due 2024

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) INTEREST. ArcelorMittal, a société anonyme organized under Luxembourg law will pay interest on the principal amount of the Securities at 3.600% per annum from July 16, 2019 until Maturity. The Company will pay interest and Additional Amounts (if any) pursuant to Section 10.11 of the Base Indenture, semi-annually in arrears on January 16 and July 16 of each year (each an Interest Payment Date) commencing on January 16, 2020, to the Holders of Securities registered as such as of close of business on January 1 and July 1 (each a Regular Record Date), immediately preceding the relevant Interest Payment Date, or on the maturity date, or date of redemption, as applicable.

If an Interest Payment Date, the maturity date, or date of redemption in respect of the Securities is a Legal Holiday, we will pay interest or principal, as the case may be, on the next succeeding day that is not a Legal Holiday. Payments postponed to the next Business Day in this situation will be treated under this Indenture as if they were made on the original due date. Postponement of this kind will not result in a default under the Securities or this Indenture, and no interest will accrue on the postponed amount from the original due date to the next day that is a Business Day.

Interest on the Securities will accrue from the Closing Date or, if interest has already been paid, from the date it was most recently paid to (but excluding) the relevant interest payment date (each such period, an “Interest Period”). Interest on the Securities will be calculated in accordance with Section 3.10 of the Base Indenture.

Interest will cease to accrue on the Securities on the due date for their redemption, unless, upon such due date, payment of principal is improperly withheld or refused or if default is otherwise made in respect of payment of principal, in which case interest will continue to accrue on the Securities at the rates set forth above, as the case may be, until the earlier of (a) the day on which all sums due in respect of such Securities up to that day are received by the relevant Holder or (b) the day falling seven days after the Securities Administrator has notified the Holders of receipt of all sums due in respect of the such Securities up to that seventh day, except to the extent that there is failure in the subsequent payment to the relevant Holders following such notification.

(2) DEFAULTED INTEREST. Any interest on the Securities which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Company, notice whereof shall be given to Holders of Securities of this series not more than 15 days and not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

A-3

(3) METHOD OF PAYMENT. The Company will pay interest on the Securities (except Defaulted Interest) and Additional Amounts (if any) to the Persons who are registered Holders of Securities at the close of business in New York City on January 1 or July 1 (whether or not a Business Day) immediately preceding the Interest Payment Date, except as provided in Section 3.07 of the Base Indenture with respect to Defaulted Interest. The Securities will be payable as to principal, interest and Additional Amounts (if any) at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest and Additional Amounts (if any) may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, interest and Additional Amounts (if any) on, all Securities the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

(4) PAYING AGENT AND SECURITY REGISTRAR. Initially, Citibank, N.A., the Securities Administrator under the Indenture, will act as Paying Agent and Security Registrar. The Company may appoint one or more Co-Registrars and one or more additional Paying Agents. The Company may change any Paying Agent or Security Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

(5) INDENTURE. The Company issued the Securities under an Indenture dated as of June 1, 2015, as supplemented by the Third Supplemental Indenture dated July 16, 2019, between the Company, the Securities Administrator and the Trustee. The terms of the Securities include those stated in the Indenture and those expressly made part of the Indenture by reference to the Trust Indenture Act as in effect on the date of the Indenture and, to the extent required by any amendment after such date, as so amended. The Securities are subject to all such terms, and Holders are referred to the Indenture and the U.S. Trust Indenture Act for a statement of such terms. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

(6) REDEMPTION FOR TAXATION REASONS. The Securities may be redeemed, at the Company’s option, in whole but not in part, upon giving not less than 30 days’ nor more than 60 days’ notice to the Holders (which notice will be irrevocable), at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest (including any Additional Amounts), if any, up to but excluding the Tax Redemption Date if, as a result of:

(a) any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of a Relevant Jurisdiction affecting taxation; or

(b) any change in, or amendment to, an official position regarding the application or written interpretation of such laws, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction),

A-4

Securities or the Indenture, with respect to any payment due or to become due under the Securities or the Indenture, the Company or its successor entity, as the case may be, is, or on the next Interest Payment Date would be, required to pay Additional Amounts, and such requirement cannot be avoided by the Company or its successor entity, as the case may be, taking reasonable measures available to it (including, for the avoidance of doubt, the appointment of a new paying agent where this would be reasonable); provided that for the avoidance of doubt changing the jurisdiction of the Company or any successor entity is not a reasonable measure for the purposes of this section; and provided, further that no such notice of redemption will be given earlier than 60 days prior to the earliest date on which we, or any successor entity, as the case may be, would be obligated to pay such Additional Amounts if a payment in respect of the Securities were then due.

Any Securities that are redeemed will be cancelled.

(7) REDEMPTION AT THE OPTION OF THE COMPANY. Section 11.03 of the Base Indenture shall be applicable to the Securities. The Company will have the right to redeem the Securities of this series, in whole at any time, or in part from time to time, at the Company’s option, on at least 30 days’ but no more than 60 days’ prior written notice given to the registered Holders of such Securities to be redeemed. Upon redemption of the Securities, the Company will pay a redemption price equal to the greater of (1) 100% of the principal amount of the Securities to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments of the Securities to be redeemed, discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points (which shall be the Additional Basis Points for the Securities), in each case plus accrued and unpaid interest thereon up to but excluding the Redemption Date. The Reference Treasury Dealer means for the Securities: (i) each of BofA Securities, Inc., Citigroup Global Markets Inc., ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Co. LLC, ▇.▇. ▇▇▇▇▇▇ Securities LLC and RBC Capital Markets, LLC (or their respective affiliates that are primary U.S. Government securities dealers), and their respective successors, or if at any time any of the above is not a primary U.S. Government securities dealer, one other nationally recognized investment banking firm selected by the Company that is a primary U.S. Government securities dealer; and (iii) one other leading primary U.S. Government securities dealer designated by the Company.

(8) MANDATORY REDEMPTION. The Company is not required to make mandatory redemption or sinking fund payments with respect to the Securities.

(9) NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder at its registered address.

(10) OFFER TO PURCHASE UPON A CHANGE OF CONTROL. Section 10.12 of the Base Indenture shall be applicable to the Securities. Upon the occurrence of a Change of Control, unless the Company has exercised its right to redeem the Securities under Section 3.1 or under Section 3.2 of the Third Supplemental Indenture, or unless the Change of Control Payment Date would fall on or after the maturity date of the Securities, the Company will make an offer to purchase all or a portion of each Holder’s Securities pursuant to the Change of Control Offer, at a purchase price equal to 101% of the principal amount tendered plus accrued and unpaid interest, if any, up to but excluding the date of purchase, subject to the provisions of the Indenture.

A-5

(11) LEGAL DEFEASANCE AND DISCHARGE. Section 4.02 of the Base Indenture shall be applicable to the Securities.

(12) COVENANT DEFEASANCE. Section 4.03 of the Base Indenture shall be applicable to the Securities.

(13) SATISFACTION AND DISCHARGE. The Indenture specifies the means by which it may be discharged and cease to be of further effect with respect to the Securities.

(14) DENOMINATIONS, TRANSFER, EXCHANGE. The Securities are in registered form without coupons in a minimum denomination of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Security Registrar, the Securities Administrator and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Security or portion of a Security selected for redemption. Also, the Company need not exchange or register the transfer of any Securities for a period of 15 days before a selection of Securities of such series to be redeemed or selected for redemption or during the period between a record date and the corresponding Interest Payment Date.

(15) PERSONS DEEMED OWNERS. The registered Holder of a Security may be treated as its owner for all purposes.

(16) AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company, the Securities Administrator and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As set forth in the Indenture, the Indenture may be amended or modified without the consent of any Holder of Securities in order, among other things: (i) to cure any ambiguity, defect or inconsistency; (ii) to provide for the issuance of additional Securities in accordance with the limitations set forth in the Indenture; (iii) to add to the covenants of the Company, for the benefit of holders of the Securities or to surrender any power or right conferred upon the Company; (iv) to add or modify for the benefit of holders of the Securities any events of default;

A-6

As set forth in the Indenture, without the consent of each Holder of an Outstanding Security affected, no amendment may, among other things: (i) modify the Stated Maturity of the Securities or the dates on which interest is payable in respect of the Securities; (ii) change the method in which amounts of payments of principal or any interest thereon is determined; (iii) reduce the principal amount of, or interest on, the Securities; (iv) reduce the premium payable upon redemption; (v) change the obligation of the Company to pay Additional Amounts; (vi) change the currency of payment of the Securities; (vii) change the obligation of the Company to maintain an office or agency in the places and for the purposes specified in the Indenture, (viii) impair the right of the Holders of Securities to institute suit for the enforcement of any payment on or after the date due; (ix) reduce the percentage in principal amount of the Outstanding Securities, the consent of whose Holders is required for any modification of or waiver of compliance with any provision of the Indenture or defaults under the Indenture and their consequences; and (x) modify the provisions of the Indenture regarding the quorum required at any meeting of Holders.

(17) DEFAULTS AND REMEDIES. Each of the following is an “Event of Default”:

(2) default in the payment of interest (if any) and Additional Amounts (if any) on any Security of a series when due, which continues for 30 days;

(3) the Company’s failure to comply with any other obligation contained in the Indenture (other than a covenant default in whose performance or whose breach is elsewhere in Section 5.01 of the Base Indenture specifically dealt with), and continuance of such default or breach for a period of 60 days after there has been given to the Company by the Trustee or the Securities Administrator written notice, as provided in accordance with Section 1.05 of the Base Indenture, specifying such default or breach and requiring it to be remedied;

(4) the Company’s failure, or the failure of any Material Subsidiary, (a) to pay the principal of any indebtedness for borrowed money, including obligations evidenced by any mortgage, indenture, bond, debenture, note, guarantee or other similar instruments on the scheduled or original date due (following the giving of such notice, if any, as

A-7

required under the document governing such indebtedness and as extended by any applicable cure period) or (b) to observe or perform any agreement or condition relating to such indebtedness such that such indebtedness has come due prior to its stated maturity and such acceleration has not been cured, unless (in the case of clauses (a) and (b)) (i) the aggregate amount of such indebtedness is less than €100,000,000 or (ii) the question of whether such indebtedness is due has been disputed in good faith by appropriate proceedings and such dispute has not been finally adjudicated against the Company or the Material Subsidiary, as the case may be;

(5) if the Company is (or is deemed by law or a court to be) insolvent or bankrupt or presents a request for controlled management (gestion contrôlée) or is granted a moratorium on payments or is unable to pay its debts, stops, suspends or threatens to stop or suspend payment of all or a material part of (or of a particular type of) its debts within the meaning of any applicable law, proposes or makes any agreement for the deferral, rescheduling or other readjustment of all of (or all of a particular type of) its debts (or of any part which it will or might otherwise be unable to pay when due), proposes or makes a general assignment or any arrangement or composition with or for the benefit of the relevant creditors in respect of any of such debts or a moratorium is agreed or declared in respect of or affecting all or any part of (or of a particular type of) the debts of the Company or any event occurs which under the laws of any relevant jurisdiction has an analogous effect to any of the foregoing events; or

(6) if any Material Subsidiary is (or is deemed by law or a court to be) insolvent or bankrupt or presents a request for controlled management (gestion contrôlée) or is granted a moratorium on payments or is unable to pay its debts, stops, suspends or threatens to stop or suspend payment of all or a material part of (or of a particular type of) its debts within the meaning of any applicable law, proposes or makes any agreement for the deferral, rescheduling or other readjustment of all of (or all of a particular type of) its debts (or of any part which it will or might otherwise be unable to pay when due), proposes or makes a general assignment or any arrangement or composition with or for the benefit of the relevant creditors in respect of any of such debts or a moratorium is agreed or declared in respect of or affecting all or any part of (or of a particular type of) the debts of any such Material Subsidiary or any event occurs which under the laws of any relevant jurisdiction has an analogous effect to any of the foregoing events (in each case, a “Material Subsidiary Insolvency Event”), provided that no Event of Default under this paragraph (ii) will occur in relation to any such Material Subsidiary Insolvency Event unless (x) the credit rating assigned by any Rating Agency to the long-term, unsecured and unsubordinated indebtedness of the Company within the period of 60 days immediately following such Material Subsidiary Insolvency Event is less than the credit rating assigned by such agency to the long-term, unsecured and unsubordinated indebtedness of the Company immediately prior to or on the effective date of such Material Subsidiary Insolvency Event and (y) a Rating Agency making a Rating Downgrade publicly announces or confirms that such Rating Downgrade was the result of any event or circumstance comprised in or arising as a result of, or in respect of, such Material Subsidiary Insolvency Event.

A-8

Upon the occurrence and continuation of any Event of Default, then in every such case the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Securities of the affected series may declare the principal amount of the outstanding Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), in accordance with Section 1.05 of the Base Indenture. Upon any such declaration, the Securities of such series shall become due and payable immediately.

At any time after such a declaration of acceleration with respect to outstanding Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay

(a) all overdue interest on all Securities of that series,

(b) the principal of (and premium (if any) on) any Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities,

(c) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and

(d) all sums paid or advanced by either of the Trustee or the Securities Administrator hereunder and the reasonable and documented compensation, expenses, disbursements and advances of each of the Trustee and the Securities Administrator, its agents and counsel;

and

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal and other amounts of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.04 of the Base Indenture.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

The Holders of a majority in aggregate principal amount of the outstanding Securities of any series by notice to the Trustee may waive any past default under the Indenture affecting such series, except an uncured default in the payment of principal of or interest on such series of Securities or an uncured default relating to a covenant or provision of the Indenture that cannot be modified or amended without the consent of each affected Holder.

Holders of a majority in aggregate principal amount of the outstanding Securities of a series will have the right to direct the time, method and place of conducting any proceeding for

A-9

exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, in each case with respect to such series and subject to the limitations specified herein. Subject to Article 6 of the Base Indenture relating to the Trustee’s duties, neither of the Trustee nor the Securities Administrator will be under any obligation to exercise any of its rights and powers under the Indenture unless such Holder has offered an indemnity to its reasonable satisfaction against any loss, costs, expenses and liabilities it may incur.

No Holder of Securities of any series will have any right to institute any proceeding with respect to the Indenture or the Securities of the series or for any remedy thereunder, unless:

(1) such Holder has previously given written notice to the Trustee at its Corporate Trust Office of a continuing Event of Default under the Securities of the series has occurred;

(2) Holders of not less than 25% in aggregate principal amount of the outstanding Securities of the relevant series have made a written request to the Trustee to institute the proceedings in respect of the Event of Default in its own name as Trustee under the Indenture;

(3) the Holders of the Securities of the relevant series have offered to the Trustee reasonable indemnity against the cost and other liabilities of instituting a proceeding and provided a written request to the Trustee at its Corporate Trust Office;

(4) the Trustee for 60 days thereafter has failed to institute any such proceeding;

(5) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Securities of the relevant series have not given the Trustee a direction that is inconsistent with such written request; and

(6) the terms of such series of Securities do not prohibit such remedy to be sought by the Trustee and/or the Holders,

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under the Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders

Notwithstanding any other provision of the Indenture, the right of any Holder of a Security to receive payment of principal of, and interest (if any) and Additional Amounts (if any) on the Security, on or after the respective due dates expressed in the Security (including in connection with a Change of Control Offer), or to institute a suit for the enforcement of any such payment on or after such respective dates, shall not be impaired without the consent of such Holder.

A-10

(18) TRUSTEE AND SECURITIES ADMINISTRATOR DEALINGS WITH COMPANY. Each of the Trustee and the Securities Administrator, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee or Securities Administrator, as applicable. However, in the event that the Trustee acquires any conflicting interest as defined under the Trust Indenture Act, it must eliminate such conflict within 90 days, or resign.

(19) NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator or stockholder of the Company, as such, will 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 by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

(20) AUTHENTICATION. This Security will not be valid until authenticated by the manual signature of the Securities Administrator or an authenticating agent.

(21) ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

(22) CUSIP NUMBERS.
