 AIR PRODUCTS AND CHEMICALS, INC., a Delaware corporation (the “Issuer”),
for value received, hereby promises to pay to [*], as nominee of [*], a common depositary for Euroclear Bank SA/NV and Clearstream Banking S.A. (the “Depositary”), or registered assigns, the principal sum of [*] euros (€[*]) on the
Maturity Date specified above or upon earlier redemption or repayment at [*] (the “Paying Agent”), as Paying Agent, currently located at [*], or such other location or locations as may be provided for pursuant to the Indenture
referred to herein, in such coin, currency or currency unit specified above as at the time of payment shall be legal tender for the payment of public and private debts, and to pay interest annually on the Interest Payment Date in each year
and on the Maturity Date or upon earlier redemption or repayment; commencing with the first Interest Payment Date following the Original Issue Date specified above on said principal sum at the Interest Rate specified above from the most recent date
to which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, from the Original Issue Date, until the principal hereof becomes due and payable; provided, however, that any payment of
principal, interest, or premium, if any, to be made on an Interest Payment Date, on the Maturity Date or on a date fixed for redemption or repayment which is not a Business Day (as hereinafter defined) shall be made on the next succeeding Business
Day with the same force and effect as if made on the Interest Payment Date, on the Maturity Date or on the date fixed for redemption or repayment, as the case may be, and no additional interest shall accrue as a result of such delayed payment. For
purposes of this Note, “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in New York, New
York or London, England, and on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 System) or any successor thereto, is open. 

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will be paid to the person in whose name this
Note (or one or more predecessor Notes) is registered at the close of business on the Record Date (whether or not a Business Day) immediately preceding such Interest Payment Date and interest payable on the Maturity Date or upon earlier redemption
or repayment will be payable to the person to whom principal is payable, except that, if this Note is issued between a Record Date and the initial Interest Payment Date relating to such Record Date, interest for the period beginning on the Original
Issue Date and ending on such initial Interest Payment Date shall be paid to the person to whom this Note shall have been originally issued. Payment of principal, interest and premium, if any, on this Note will be made, if at maturity or upon
earlier redemption or repayment, on the Maturity Date or the date fixed for redemption or repayment, as applicable, upon surrender of this Note at the office of the Paying Agent. All such payments shall be made in immediately available funds,
provided that this Note is presented to the Paying Agent in time for the Trustee to make such payments in such funds in accordance with its normal procedures. Payment of interest on this Note (other than interest paid on the Maturity Date or upon
earlier redemption or repayment) will be made by wire transfer to the person entitled thereto appearing on the register for the Notes on the applicable Record Date; provided that such holder shall have designated such account by written notice to
the Trustee no later than the Record Date preceding the applicable Interest Payment Date. Notwithstanding the foregoing, payments of principal, interest and premium, if any, on Global Securities shall be made in accordance with the Depositary’s
procedures. Any interest not punctually paid or duly provided for shall be payable as provided in the Indenture referred to on the reverse hereof.

 Interest will be computed on the basis of the actual number of days in the period for which
interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or from May 5, 2020, if no interest has been paid on the Notes), to but excluding the next scheduled Interest
Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. 

Pursuant to Section 2.3(12) of the Indenture, payments of principal, interest and premium, if any, of the Notes are payable in euros;
provided, however, with the sole exception that if, on or after [*], the euro is unavailable to the Issuer due to the imposition of exchange controls or other circumstances beyond the control of the Issuer or if the euro is no longer being used by
the then-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 the
Notes will be made in U.S. dollars until the euro is again available to the Issuer or so used. In such circumstances, the amount payable on any date in euros will be converted into U.S. dollars in accordance with Sections 2.13(e) and (f) of the
Indenture. Any payment in respect of the Notes so made in U.S. dollars will not constitute an Event of Default under the Notes or the Indenture. Section 2.13(b) of the Indenture shall not apply with respect to the Notes. 

REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL HAVE THE SAME
EFFECT AS THOUGH FULLY SET FORTH AT THIS PLACE. 
 This Note shall not be valid or become obligatory for any purpose until the certificate
of authentication hereon shall have been signed by or on behalf of the Trustee under the Indenture referred to on the reverse hereof.

 REVERSE OF NOTE 

This Note is one of a duly authorized issue of a series of notes of the Issuer (hereinafter called the “Securities”) of the
series hereinafter specified, all issued or to be issued under and pursuant to an indenture dated as of April 30, 2020 (the “Indenture”), duly executed and delivered by the Issuer to The Bank of New York Mellon Trust Company,
N.A., as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the holders (the words “holders” or “holder” meaning the registered holders or registered holder of the Securities). The Securities may be issued in one or more series, which different series
(and which securities issued within each series) may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption or repayment provisions (if
any), may be subject to different sinking fund or analogous provisions (if any), may be subject to different Events of Default (as defined in the Indenture) and may otherwise vary as in the Indenture provided. This Note is one of a series designated
as “0.500% Notes due 2028” (the “Notes”) of the Issuer, initially limited in aggregate principal amount to €500,000,000, subject to the right of the Issuer to issue unlimited additional Securities under the Indenture
having the same term as the Notes without the consent of the holders of any Securities; provided that no additional Notes having such similar terms may be issued if an Event of Default has occurred and is continuing with respect to the Notes or if
such additional Notes will not be fungible with the previously issued Notes for federal income tax purposes. 
 This Note will constitute
part of the senior debt of the Issuer and will rank pari passu with all other unsecured and unsubordinated indebtedness of the Issuer. This Note will be issuable in fully registered form in denominations of €100,000 and additional
multiples of €1,000. 
 In case an Event of Default with respect to the Notes shall have occurred and be continuing, the principal
hereof 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. 

Optional Redemption 
 At the
Issuer’s option, the Notes may be redeemed, in whole or in part, upon mailing a notice of such redemption not less than 15 days nor more than 60 days prior to the date fixed for redemption to the holders of the Notes at their last registered
addresses, all as provided in the Indenture. 
 If the Issuer redeems all or any part of the Notes prior to the applicable Par Call Date (as
defined below), it will pay a redemption price equal to the greater of: (i) 100% of the principal amount of the Notes being redeemed; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest of the
Notes being redeemed, that would be due if such series of Notes matured on the applicable Par Call Date (in each case, not including the amount, if any, of accrued and unpaid interest to, but excluding, the redemption date) discounted to the
redemption date on an annual basis (ACTUAL/ACTUAL (ICMA)) using a discount rate equal to the Comparable Government Bond Rate plus 20 basis points; plus, in each case, any 

  
 R-1 












 
accrued and unpaid interest to, but excluding, the redemption date. If the Issuer redeems all or any part of the Notes on or after the applicable Par Call Date, the Issuer will pay a redemption
price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest to, but excluding, the redemption date. The redemption price shall be calculated by the Company. 

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an
independent investment bank selected by the Issuer, a German Bundesanleihe security whose maturity is closest to the maturity of the Notes being redeemed (assuming that the Notes to be redeemed matured on the applicable Par Call Date), or if
such independent investment bank in its discretion considers that such similar bond is not in issue, such other German Bundesanleihe security as such independent investment bank may, with the advice of three brokers of, or market makers in,
German Bundesanleihe securities selected by such independent investment bank, determine to be appropriate for determining the Comparable Government Bond Rate. 

“Comparable Government Bond Rate” means the price, expressed as a percentage (rounded to three decimal places, 0.0005 being
rounded upwards), at which the gross redemption yield on the Notes being redeemed, if they were to be purchased at such price prior to the applicable Par Call Date on the third business day prior to the date fixed for redemption, would be equal to
the gross redemption yield on such business day of the Comparable Government Bond on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such business day as determined by an independent
investment bank selected by the Issuer. 
 “Par Call Date” means February 5, 2028. 

Redemption for Tax Reasons 
 If, as
a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 28, 2020, the Issuer becomes or, based upon a written opinion of
nationally recognized independent counsel selected by the Issuer, there is a substantial probability that the Issuer will become obligated within 90 days to pay additional amounts as described below with respect to the Notes, then the Issuer may, at
any time and at its option, redeem, in whole, but not in part, the Notes on not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, together with accrued and
unpaid interest on the Notes to, but excluding, the date fixed for redemption. 

  
 R-2 












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

	 	(1)	 to any tax, assessment or other governmental charge that would not have been imposed but for the holder, a
fiduciary, settlor, beneficiary, member or shareholder of the holder, or a person holding a power over an estate or trust administered by a fiduciary holder, being treated as: 



 

	 	(a)	 being or having been engaged in a trade or business in the United States, or having or having had a permanent
establishment in the United States; 


  

	 	(b)	 having a current or former connection with the United States (other than a connection arising solely as a
result of the ownership of the Notes, the receipt of any payment in respect of the Notes or the enforcement of any rights under the Indenture), including being or having been a citizen or resident of the United States; 



 

	 	(c)	 being or having been a personal holding company, a passive foreign investment company or a controlled foreign
corporation for U.S. federal income tax purposes, a foreign tax exempt organization, or a corporation that has accumulated earnings to avoid United States federal income tax; 



 

	 	(d)	 being or having been a “10-percent shareholder” of the
Issuer, as defined in section 871(h)(3) of the United States Internal Revenue Code of 1986, as amended (the “Code”) or any successor provision; or 


  

	 	(e)	 being a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the
ordinary course of its trade or business, within the meaning of section 881(c)(3) of the Code or any successor provision; 


  

	 	(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, partnership or limited liability company, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership or limited liability company 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 would not have been imposed but for the failure of the
holder or beneficial owner 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 or any taxing authority therein 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 from the
payment; 



  
 R-3 













	 	(5)	 to any tax, assessment or other governmental charge that would not have been imposed but for 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, capital gains 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 Note, if such payment can be made without such withholding by any other paying agent; 


  

	 	(8)	 to any tax, assessment or other governmental charge that would not have been imposed but for the presentation
by the holder of any Note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;



  

	 	(9)	 to any tax, assessment or other governmental charge required to be withheld or deducted that is imposed on a
payment pursuant to Sections 1471 through 1474 of the Code (or any amended or successor version of such Sections that is substantively comparable and not materially more onerous to comply with), any Treasury regulations promulgated thereunder, or
any other official interpretations thereof, any agreement (including any intergovernmental agreement) entered into in connection therewith, or any law, regulation or other official guidance enacted in any jurisdiction implementing the Foreign
Account Tax Compliance Act (“FACTA”) or an intergovernmental agreement in respect of FATCA; or 


  

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



Except as specifically provided above, the Issuer will not be required to pay additional amounts in respect of any tax, assessment or other
governmental charge.

United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes,
(ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S.
federal income tax purposes) or treated as a domestic corporation under Section 7874(b) of the Code, (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S.
court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person. 

  
 R-4 












 Change of Control Offer 

Upon the occurrence of a Change of Control Triggering Event, the Issuer will be required to make an offer (a “Change of Control
Offer”) to each holder of Notes to repurchase all or any part (equal to €100,000 or an integral multiple of €1,000 thereof) of such holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof,
together with accrued and unpaid interest thereon to the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Issuer will be required to mail (or otherwise
transmit in accordance with DTC procedures) a notice to each holder stating: 
  

	 	(1)	 that the Change of Control Offer is being made pursuant to the covenant entitled “Change of Control and
Ratings Decline”; 


  

	 	(2)	 the purchase price and the purchase date, which shall be no earlier than 30 days nor later than 45 days after
the date such notice is mailed (the “Change of Control Payment Date”);  


  

	 	(3)	 that any Notes not tendered will continue to accrue interest in accordance with the terms of the Indenture and
this Note; 


  

	 	(4)	 that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for
payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 


  

	 	(5)	 that holders will be entitled to withdraw their election if the paying agent receives, not later than the close
of business on the fifth business day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the holder, the principal amount of Notes delivered for purchase, and a statement that such holder is
unconditionally withdrawing its election to have such Notes purchased; 


  

	 	(6)	 that holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to
the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to €100,000 in principal amount or an integral multiple of €1,000 in excess thereof; and 



 

	 	(7)	 any other information material to such holder’s decision to tender Notes. 



The Issuer will not be required to make a Change of Control Offer following a Change of Control Triggering Event if a third party makes a
Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Notes applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under
such Change of Control Offer. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon such Change of Control, if a definitive agreement is in place
for the Change of Control at the time of making the Change of Control Offer. 

  
 R-5

“Change of Control” means the occurrence of any one of the following:

which is that any person (including any “person” (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) other than the Issuer or one of its subsidiaries)
becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Issuer’s
outstanding Voting Stock, measured by voting power rather than number of shares; or 


  

	 	(2)	 the adoption of a plan relating to the liquidation or dissolution of the Issuer. 



Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (1) the Issuer becomes a direct or
indirect wholly owned subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Issuer’s Voting
Stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of
the Voting Stock of such holding company. 
 “Change of Control Triggering Event” means the occurrence of both a Change of
Control and a Ratings Decline. 
 “Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent
under any successor rating category of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P). In the event that the Issuer shall select any
other Rating Agency, the equivalent of such ratings by such Rating Agency shall be used. 
 “Moody’s” means

 “Rating Agency”

long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) (the “Trigger Period”), (a) if two or more Rating Agencies are providing a rating for the Notes at the
commencement of any Trigger Period, the rating of the Notes shall be reduced by at least two Rating Agencies and the Notes shall be rated below Investment Grade by each of such Rating Agencies or (b) if only one Rating Agency is providing a
rating for the 

  
 R-6 












 
Notes at the commencement of any Trigger Period, the rating of the Notes shall be reduced by such Rating Agency and the Notes shall be rated below Investment Grade by such Rating Agency. Neither
the Trustee nor the Paying Agent shall be responsible for monitoring the Issuer’s Investment Grade status or determining whether a Ratings Decline has occurred. 

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors. 

“Voting Stock” with respect to any person, means securities of any class of Capital Stock of such person entitling the
holders thereof (whether at all times or only so long as no senior class of stock or other relevant equity interest has voting power by reason of any contingency) to vote in the election of members of the board of directors of such person. 

The Issuer shall comply in all material respects with the requirements of Regulation 14E 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 Triggering Event. 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 Issuer shall comply with those securities laws and regulations and shall not be deemed to have breached the Issuer’s obligations under the Change of Control
Offer provisions of the Notes by virtue of any such conflict. 
 Miscellaneous 

The Notes are subject to the defeasance provisions set forth in Section 10.2 of the Indenture.

 AIR PRODUCTS AND CHEMICALS, INC., a Delaware corporation (the “Issuer”),
for value received, hereby promises to pay to [*], as nominee of [*], a common depositary for Euroclear Bank SA/NV and Clearstream Banking S.A. (the “Depositary”), or registered assigns, the principal sum of [*] euros (€[*]) on the
Maturity Date specified above or upon earlier redemption or repayment at [*] (the “Paying Agent”), as Paying Agent, currently located at [*], or such other location or locations as may be provided for pursuant to the Indenture
referred to herein, in such coin, currency or currency unit specified above as at the time of payment shall be legal tender for the payment of public and private debts, and to pay interest annually on the Interest Payment Date in each year
and on the Maturity Date or upon earlier redemption or repayment; commencing with the first Interest Payment Date following the Original Issue Date specified above on said principal sum at the Interest Rate specified above from the most recent date
to which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, from the Original Issue Date, until the principal hereof becomes due and payable; provided, however, that any payment of
principal, interest, or premium, if any, to be made on an Interest Payment Date, on the Maturity Date or on a date fixed for redemption or repayment which is not a Business Day (as hereinafter defined) shall be made on the next succeeding Business
Day with the same force and effect as if made on the Interest Payment Date, on the Maturity Date or on the date fixed for redemption or repayment, as the case may be, and no additional interest shall accrue as a result of such delayed payment. For
purposes of this Note, “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in New York, New
York or London, England, and on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 System) or any successor thereto, is open. 

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will be paid to the person in whose name this
Note (or one or more predecessor Notes) is registered at the close of business on the Record Date (whether or not a Business Day) immediately preceding such Interest Payment Date and interest payable on the Maturity Date or upon earlier redemption
or repayment will be payable to the person to whom principal is payable, except that, if this Note is issued between a Record Date and the initial Interest Payment Date relating to such Record Date, interest for the period beginning on the Original
Issue Date and ending on such initial Interest Payment Date shall be paid to the person to whom this Note shall have been originally issued. Payment of principal, interest and premium, if any, on this Note will be made, if at maturity or upon
earlier redemption or repayment, on the Maturity Date or the date fixed for redemption or repayment, as applicable, upon surrender of this Note at the office of the Paying Agent. All such payments shall be made in immediately available funds,
provided that this Note is presented to the Paying Agent in time for the Trustee to make such payments in such funds in accordance with its normal procedures. Payment of interest on this Note (other than interest paid on the Maturity Date or upon
earlier redemption or repayment) will be made by wire transfer to the person entitled thereto appearing on the register for the Notes on the applicable Record Date; provided that such holder shall have designated such account by written notice to
the Trustee no later than the Record Date preceding the applicable Interest Payment Date. Notwithstanding the foregoing, payments of principal, interest and premium, if any, on Global Securities shall be made in accordance with the Depositary’s
procedures. Any interest not punctually paid or duly provided for shall be payable as provided in the Indenture referred to on the reverse hereof.

 Interest will be computed on the basis of the actual number of days in the period for which
interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or from May 5, 2020, if no interest has been paid on the Notes), to but excluding the next scheduled Interest
Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. 

Pursuant to Section 2.3(12) of the Indenture, payments of principal, interest and premium, if any, of the Notes are payable in euros;
provided, however, with the sole exception that if, on or after [*], the euro is unavailable to the Issuer due to the imposition of exchange controls or other circumstances beyond the control of the Issuer or if the euro is no longer being used by
the then-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 the
Notes will be made in U.S. dollars until the euro is again available to the Issuer or so used. In such circumstances, the amount payable on any date in euros will be converted into U.S. dollars in accordance with Sections 2.13(e) and (f) of the
Indenture. Any payment in respect of the Notes so made in U.S. dollars will not constitute an Event of Default under the Notes or the Indenture. Section 2.13(b) of the Indenture shall not apply with respect to the Notes. 

REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL HAVE THE SAME
EFFECT AS THOUGH FULLY SET FORTH AT THIS PLACE. 
 This Note shall not be valid or become obligatory for any purpose until the certificate
of authentication hereon shall have been signed by or on behalf of the Trustee under the Indenture referred to on the reverse hereof.

 REVERSE OF NOTE 

This Note is one of a duly authorized issue of a series of notes of the Issuer (hereinafter called the “Securities”) of the
series hereinafter specified, all issued or to be issued under and pursuant to an indenture dated as of April 30, 2020 (the “Indenture”), duly executed and delivered by the Issuer to The Bank of New York Mellon Trust Company,
N.A., as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the holders (the words “holders” or “holder” meaning the registered holders or registered holder of the Securities). The Securities may be issued in one or more series, which different series
(and which securities issued within each series) may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption or repayment provisions (if
any), may be subject to different sinking fund or analogous provisions (if any), may be subject to different Events of Default (as defined in the Indenture) and may otherwise vary as in the Indenture provided. This Note is one of a series designated
as “0.800% Notes due 2032” (the “Notes”) of the Issuer, initially limited in aggregate principal amount to €500,000,000, subject to the right of the Issuer to issue unlimited additional Securities under the Indenture
having the same term as the Notes without the consent of the holders of any Securities; provided that no additional Notes having such similar terms may be issued if an Event of Default has occurred and is continuing with respect to the Notes or if
such additional Notes will not be fungible with the previously issued Notes for federal income tax purposes. 
 This Note will constitute
part of the senior debt of the Issuer and will rank pari passu with all other unsecured and unsubordinated indebtedness of the Issuer. This Note will be issuable in fully registered form in denominations of €100,000 and additional
multiples of €1,000. 
 In case an Event of Default with respect to the Notes shall have occurred and be continuing, the principal
hereof 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. 

Optional Redemption 
 At the
Issuer’s option, the Notes may be redeemed, in whole or in part, upon mailing a notice of such redemption not less than 15 days nor more than 60 days prior to the date fixed for redemption to the holders of the Notes at their last registered
addresses, all as provided in the Indenture. 
 If the Issuer redeems all or any part of the Notes prior to the applicable Par Call Date (as
defined below), it will pay a redemption price equal to the greater of: (i) 100% of the principal amount of the Notes being redeemed; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest of the
Notes being redeemed, that would be due if such series of Notes matured on the applicable Par Call Date (in each case, not including the amount, if any, of accrued and unpaid interest to, but excluding, the redemption date) discounted to the
redemption date on an annual basis (ACTUAL/ACTUAL (ICMA)) using a discount rate equal to the Comparable Government Bond Rate plus 20 basis points; plus, in each case, any 

  
 R-1 












 
accrued and unpaid interest to, but excluding, the redemption date. If the Issuer redeems all or any part of the Notes on or after the applicable Par Call Date, the Issuer will pay a redemption
price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest to, but excluding, the redemption date. The redemption price shall be calculated by the Company. 

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an
independent investment bank selected by the Issuer, a German Bundesanleihe security whose maturity is closest to the maturity of the Notes being redeemed (assuming that the Notes to be redeemed matured on the applicable Par Call Date), or if
such independent investment bank in its discretion considers that such similar bond is not in issue, such other German Bundesanleihe security as such independent investment bank may, with the advice of three brokers of, or market makers in,
German Bundesanleihe securities selected by such independent investment bank, determine to be appropriate for determining the Comparable Government Bond Rate. 

“Comparable Government Bond Rate” means the price, expressed as a percentage (rounded to three decimal places, 0.0005 being
rounded upwards), at which the gross redemption yield on the Notes being redeemed, if they were to be purchased at such price prior to the applicable Par Call Date on the third business day prior to the date fixed for redemption, would be equal to
the gross redemption yield on such business day of the Comparable Government Bond on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such business day as determined by an independent
investment bank selected by the Issuer. 
 “Par Call Date” means February 5, 2032. 

Redemption for Tax Reasons 
 If, as
a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 28, 2020, the Issuer becomes or, based upon a written opinion of
nationally recognized independent counsel selected by the Issuer, there is a substantial probability that the Issuer will become obligated within 90 days to pay additional amounts as described below with respect to the Notes, then the Issuer may, at
any time and at its option, redeem, in whole, but not in part, the Notes on not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, together with accrued and
unpaid interest on the Notes to, but excluding, the date fixed for redemption. 

  
 R-2 












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

	 	(1)	 to any tax, assessment or other governmental charge that would not have been imposed but for the holder, a
fiduciary, settlor, beneficiary, member or shareholder of the holder, or a person holding a power over an estate or trust administered by a fiduciary holder, being treated as: 



 

	 	(a)	 being or having been engaged in a trade or business in the United States, or having or having had a permanent
establishment in the United States; 


  

	 	(b)	 having a current or former connection with the United States (other than a connection arising solely as a
result of the ownership of the Notes, the receipt of any payment in respect of the Notes or the enforcement of any rights under the Indenture), including being or having been a citizen or resident of the United States; 



 

	 	(c)	 being or having been a personal holding company, a passive foreign investment company or a controlled foreign
corporation for U.S. federal income tax purposes, a foreign tax exempt organization, or a corporation that has accumulated earnings to avoid United States federal income tax; 



 

	 	(d)	 being or having been a “10-percent shareholder” of the
Issuer, as defined in section 871(h)(3) of the United States Internal Revenue Code of 1986, as amended (the “Code”) or any successor provision; or 


  

	 	(e)	 being a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the
ordinary course of its trade or business, within the meaning of section 881(c)(3) of the Code or any successor provision; 


  

	 	(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, partnership or limited liability company, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership or limited liability company 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 would not have been imposed but for the failure of the
holder or beneficial owner 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 or any taxing authority therein 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 from the
payment; 



  
 R-3 













	 	(5)	 to any tax, assessment or other governmental charge that would not have been imposed but for 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, capital gains 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 Note, if such payment can be made without such withholding by any other paying agent; 


  

	 	(8)	 to any tax, assessment or other governmental charge that would not have been imposed but for the presentation
by the holder of any Note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;



  

	 	(9)	 to any tax, assessment or other governmental charge required to be withheld or deducted that is imposed on a
payment pursuant to Sections 1471 through 1474 of the Code (or any amended or successor version of such Sections that is substantively comparable and not materially more onerous to comply with), any Treasury regulations promulgated thereunder, or
any other official interpretations thereof, any agreement (including any intergovernmental agreement) entered into in connection therewith, or any law, regulation or other official guidance enacted in any jurisdiction implementing the Foreign
Account Tax Compliance Act (“FACTA”) or an intergovernmental agreement in respect of FATCA; or 


  

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



Except as specifically provided above, the Issuer will not be required to pay additional amounts in respect of any tax, assessment or other
governmental charge. 
 For the purposes of this “Redemption for Tax Reasons” section, “United States” means the
United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes,
(ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S.
federal income tax purposes) or treated as a domestic corporation under Section 7874(b) of the Code, (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S.
court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person. 

  
 R-4 












 Change of Control Offer 

Upon the occurrence of a Change of Control Triggering Event, the Issuer will be required to make an offer (a “Change of Control
Offer”) to each holder of Notes to repurchase all or any part (equal to €100,000 or an integral multiple of €1,000 thereof) of such holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof,
together with accrued and unpaid interest thereon to the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Issuer will be required to mail (or otherwise
transmit in accordance with DTC procedures) a notice to each holder stating: 
  

	 	(1)	 that the Change of Control Offer is being made pursuant to the covenant entitled “Change of Control and
Ratings Decline”; 


  

	 	(2)	 the purchase price and the purchase date, which shall be no earlier than 30 days nor later than 45 days after
the date such notice is mailed (the “Change of Control Payment Date”);  


  

	 	(3)	 that any Notes not tendered will continue to accrue interest in accordance with the terms of the Indenture and
this Note; 


  

	 	(4)	 that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for
payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 


  

	 	(5)	 that holders will be entitled to withdraw their election if the paying agent receives, not later than the close
of business on the fifth business day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the holder, the principal amount of Notes delivered for purchase, and a statement that such holder is
unconditionally withdrawing its election to have such Notes purchased; 


  

	 	(6)	 that holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to
the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to €100,000 in principal amount or an integral multiple of €1,000 in excess thereof; and 



 

	 	(7)	 any other information material to such holder’s decision to tender Notes. 



The Issuer will not be required to make a Change of Control Offer following a Change of Control Triggering Event if a third party makes a
Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Notes applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under
such Change of Control Offer. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon such Change of Control, if a definitive agreement is in place
for the Change of Control at the time of making the Change of Control Offer. 

  
 R-5

becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Issuer’s
outstanding Voting Stock, measured by voting power rather than number of shares; or 


  

	 	(2)	 the adoption of a plan relating to the liquidation or dissolution of the Issuer. 



Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (1) the Issuer becomes a direct or
indirect wholly owned subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Issuer’s Voting
Stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of
the Voting Stock of such holding company. 
 “Change of Control Triggering Event” means the occurrence of both a Change of
Control and a Ratings Decline.

long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) (the “Trigger Period”), (a) if two or more Rating Agencies are providing a rating for the Notes at the
commencement of any Trigger Period, the rating of the Notes shall be reduced by at least two Rating Agencies and the Notes shall be rated below Investment Grade by each of such Rating Agencies or (b) if only one Rating Agency is providing a
rating for the 

  
 R-6 












 
Notes at the commencement of any Trigger Period, the rating of the Notes shall be reduced by such Rating Agency and the Notes shall be rated below Investment Grade by such Rating Agency. Neither
