designated herein issued

under the within-

THE BANK OF NEW YORK MELLON, as Trustee
by
	Authorized Signatory

This security is one of a duly authorized issue of unsecured debentures, notes or other evidences of indebtedness of the Company (hereinafter called the “Securities”), of the series hereinafter specified, all issued or to be issued under an indenture dated as of October 1, 1993, duly executed and delivered by the Company to The Bank of New York Mellon, a New York banking corporation, as trustee (hereinafter called the “Trustee”), as supplemented by the First Supplemental Indenture dated as of December 15, 1995, between the Company and the Trustee, as trustee (hereinafter called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the respective rights and duties thereunder of the Trustee, the Company and the holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest at different rates, may have different conversion prices (if any), may be subject to different redemption provisions, may be subject to different sinking, purchase or analogous funds, may be subject to different covenants and Events of Default and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 3.375% Notes due 2027 of the Company (hereinafter called the “Notes”) issued under the Indenture.

In case an Event of Default with respect to the Notes, as defined in the Indenture, shall have occurred and be continuing, the principal hereof together with interest accrued thereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Securities at the time outstanding of all series to be affected (acting as one class), to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Securities of such series to be affected; provided, however, that no such supplemental indenture shall, among other things, (i) change the fixed maturity of the principal of, or any installment of principal of or interest on, or the currency of payment of, any Security; (ii) reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof; (iii) impair the right to institute suit for the enforcement of any such payment on or after the fixed maturity thereof (or, in the case of redemption, on or after the redemption date); (iv) reduce the percentage in principal amount of the outstanding Securities of any series, the consent of whose holders is required for any such supplemental indenture, or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) provided for in the Indenture; (v) change any obligation of the Company, with respect to outstanding Securities of a series, to maintain an office or agency in the places and for the purposes specified in the Indenture for such series; or (vi) modify any of the foregoing provisions or the provisions for the waiver of certain covenants and defaults, except to increase any applicable percentage of the aggregate principal amount of outstanding Securities the consent of the holders of which is required or to provide with respect to any particular series the right to condition the effectiveness of any supplemental indenture as to that series on the consent of the holders of a specified percentage of the aggregate principal amount of outstanding Securities of such series or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the holder of each outstanding Security affected thereby. It is also provided in the Indenture that the holders of a majority in aggregate principal amount of the Securities of a series at the time outstanding may on behalf of the holders of all the Securities of such series waive any past default under the Indenture with respect to such series and its consequences, except a default in the payment of the principal of, premium, if any, or interest, if any, on any Security of such series or in respect of a covenant or provision which cannot be modified without the consent of the Holder of each outstanding Security of the series affected. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, if any, and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Indenture permits the Company to Discharge its obligations with respect to the Notes on the 91st day following the satisfaction of the conditions set forth in the Indenture, which include the deposit with the Trustee of money or Foreign Government Securities or a combination thereof sufficient to pay and discharge each installment of principal of (including premium, if any, on) and interest, if any, on the outstanding Notes.

If the Company shall, in accordance with Section 901 of the Indenture, consolidate with or merge into any other corporation or convey or transfer its properties and assets substantially as an entirety to any Person, the successor shall succeed to, and be substituted for, the Person named as the “Company” on the face of this Note, all on the terms set forth in the Indenture.

The Notes are issuable in registered form without coupons in denominations of €100,000 and any integral multiple of €1,000 in excess thereof. In the manner and subject to the limitations provided in the Indenture, but without the payment of any service charge, Notes may be exchanged for an equal aggregate principal amount of Notes of other authorized denominations at the office or agency of the Company maintained for such purpose in the Borough of Manhattan, The City and State of New York, or any other office or agency designated by the Company for such purpose.

All payments of principal, interest and additional amounts, if any, including payments made upon any redemption of the Notes, will be made in euro. If the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond the Company’s control or the euro is no longer used by the member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of this Note will be made in U.S. dollars until such currency is again available to the Company or so used. The amount payable on any date in euro will be converted into U.S. dollars on the basis of the most recently available market exchange rate for the euro. Any payment in respect of this Note so made in U.S. dollars will not constitute an Event of Default as defined in the Indenture.

The Company will, subject to the exceptions and limitations set forth below, pay as additional interest on this Note such additional amounts as are necessary in order that the net payment by the Company or a paying agent of the principal of and interest on the Notes to a holder who is not a United States person (as defined below), after deduction for any present or future tax, assessment or other governmental charge of the United States or a political subdivision or taxing authority of or in the United States, imposed by withholding with respect to the payment, will not be less than the amount provided in this Note to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts shall not apply:

(2)    to any holder that is not the sole beneficial owner of the Notes, or a portion of the Notes, or that is a fiduciary or partnership, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership would not have been entitled to the payment of an additional amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment;

(3)    to any tax, assessment or other governmental charge that is imposed otherwise or withheld solely by reason of a failure of the holder or any other person to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

(4)    to any tax, assessment or other governmental charge that is imposed otherwise than by withholding by the Company or a paying agent from the payment;

(5)    to any tax, assessment or other governmental charge that is imposed or withheld solely by reason of a change in law, regulation or administrative or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever occurs later;

(6)    to any estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or similar tax, assessment or other governmental charge;

(7)    to any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal of or interest on any Notes, if such payment can be made without such withholding by any other paying agent;

(10)    in the case of any combination of items (1), (2), (3), (4), (5), (6), (7), (8) and (9).

This Note is subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable to this Note. Except as specifically provided in this Note, the Company shall not be required to make any payment with respect to any tax, assessment or other governmental charge imposed by any government or a political subdivision or taxing authority of, or in any government or political subdivision.

As used in this Note, the term “United States” means the United States of America (including the states and the District of Columbia) and its territories, possessions and other areas subject to its jurisdiction, and the term “United States person” means any individual who is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the United States, any state of the United States or the District of Columbia (other than a partnership that is not treated as a United States person under any applicable Treasury regulations), or any estate or trust the income of which is subject to United States federal income taxation regardless of its source.

If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any political subdivision or taxing authority of or in the United States), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after January 30, 2023, the Company becomes, or based upon a written opinion of independent counsel selected by the Company, will become obligated to pay additional amounts as described above with respect to this Note, then the Company may at its option redeem, in whole, but not in part, this Note on not less than 30 nor more than 60 days prior notice, at a redemption price equal to 100% of its principal amount, together with interest accrued but unpaid on this Note to the date fixed for redemption.

The Notes will be redeemable, as a whole or in part, at the Company’s option, at any time or from time to time, on at least 10 days, but not more than 60 days, prior notice to the holders of the Notes (by mail, electronic delivery or otherwise in accordance with the depositary’s procedures). Prior to the Par Call Date, as defined below, the redemption price for the Notes will be equal to the greater of:

• 100% of the principal amount of the Notes to be redeemed; and

• the sum of the present values of the Remaining Scheduled Payments, as defined below, discounted, on an annual basis (ACTUAL/ACTUAL (ICMA)) at the Comparable Government Bond Rate, as defined below, plus 20 basis points,

plus, in each case, accrued and unpaid interest on the Notes to be redeemed to, but excluding, the Redemption Date.

“Comparable Government Bond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the Comparable Government Bond, as defined below, on the basis of the middle market price of such Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an Independent Investment Banker, as defined below.

“Comparable Government Bond” with respect to any Comparable Government Bond Rate calculation means a German government bond selected by an Independent Investment Banker as having a maturity closest to the remaining term of the Notes to be redeemed (assuming, for this purpose, that the Notes matured on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities having a maturity closest to such remaining term of the Notes, or if such Independent Investment Banker in its discretion considers that such similar bond is not in issue, such other German government bond as such Independent Investment Banker may, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Company, determine to be appropriate for determining the Comparable Government Bond Rate for the Notes.

“Independent Investment Banker” means one of the Reference Bond Dealers, to be appointed by the Company.

“Par Call Date” means January 6, 2027 (one month prior to the maturity date of the Notes).

“Reference Bond Dealer” means each of Barclays Bank PLC, Citigroup Global Markets Limited, Goldman Sachs & Co. LLC, J.P. Morgan Securities plc, Merrill Lynch International, Mizuho International plc, MUFG Securities EMEA plc and The Toronto-Dominion Bank and their respective successors or a Primary Bond Dealer selected by any of them, and their respective successors; provided however, that if any of the foregoing shall cease to be a broker or dealer of, and/or market maker in, German government bonds (a “Primary Bond Dealer”), the Company will substitute therefor another nationally recognized investment banking firm that is a Primary Bond Dealer.

“Remaining Scheduled Payments” means, with respect to each Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date but for such redemption (assuming, for this purpose, that the Notes matured on the Par Call Date); provided however, that, if such Redemption Date is not an interest payment date with respect to such Note, the amount of the next succeeding scheduled interest payment thereon will be deemed to be reduced by the amount of interest accrued thereon to such Redemption Date.

The Company will notify the Trustee of the redemption price promptly after the calculation thereof and the Trustee shall not be responsible or liable for any calculation of the redemption price or of any component thereof.

On and after the Redemption Date, interest will cease to accrue on the Notes or any portion thereof called for redemption (unless we default in the payment of the redemption price and accrued and unpaid interest). On or before the Redemption Date, we will deposit with a paying agent (or the Trustee) money sufficient to pay the redemption price of and accrued and unpaid interest on the Notes to be redeemed on that date. If fewer than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected by the Trustee by a method the Trustee deems to be fair and appropriate.

Upon due presentation for registration of transfer of this Note at the office or agency of the Company for such registration in the Borough of Manhattan, The City and State of New York, or any other office or agency designated by the Company for such purpose, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange herefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue) for the purpose of receiving payment of the principal of, premium, if any, and interest on this Note, as herein provided, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice of the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, effectually satisfy and discharge liability for moneys payable on this Note.

Individual certificates will not be issued in exchange for this Note, except in the limited circumstances set forth in the following sentence or as otherwise provided for in the Indenture. If Euroclear or Clearstream notifies us that it is unwilling or unable to continue as a clearing system in connection with this Note, and in each case we do not appoint a successor clearing system within 90 days after receiving such notice from Euroclear or Clearstream, we will issue or cause to be issued individual certificates in registered form on registration of transfer of, or in exchange for, book-entry interests in this Note upon delivery of this Note for cancellation. If the Company issues definitive Notes, interest on such Notes will be payable either by check mailed to each holder or, upon application by a holder to the registrar not later than the relevant record date, by wire transfer in immediately available funds to that holder’s account, which application shall remain in effect until the holder notifies the registrar, in writing, to the contrary.

No recourse for the payment of the principal of, premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. Unless otherwise defined in this Note, all terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
