(b)    With respect to the Notes, the fourth paragraph of Section 305 of the Base Indenture is hereby amended and
restated to read as follows: 
 “Notwithstanding the foregoing, except as otherwise provided in or pursuant to the Indenture, the Global
Notes shall be exchangeable for definitive certificated Notes of like tenor in minimum denominations of €100,000 principal amount and integral multiples of €1,000 in excess thereof only if: (i) the Depository notifies the Issuer that

executed at the office or agency maintained for such purpose by the Transfer Agent. No service charge will be made for any registration of transfer, but payment of a sum sufficient to cover any tax or governmental charge payable in connection with
that registration may be required. 
 Section 1.4    Terms and Provisions of the Notes. The Notes shall be
governed by all of the terms and provisions of the Base Indenture, as supplemented by this Eighth Supplemental Indenture, and in particular, the following provisions shall be terms of the Notes: 

(a)    Registration and Form. The Notes shall be issuable in registered form without coupons in minimum
denominations of €100,000 principal amount and integral multiples of €1,000 in excess thereof. Each Note shall be dated the date of its authentication and the Notes shall be substantially in the form of Exhibit A attached hereto. 

(b)    Payment of Principal and Interest. 

(1)    The Notes shall mature, and the unpaid principal thereon, shall be payable, on September 9, 2030, subject to
the provisions of the Base Indenture. The rate per annum at which interest shall be payable on the Notes shall be 0.500%. Interest on the Notes will be payable annually in arrears on each September 9, commencing on September 9, 2022 (each,
an “Interest Payment Date”) and on the Stated Maturity as specified in this Section 1.4(b), to the Persons in whose names the Notes are registered in the Security Register applicable to the Notes at the close of business on
August 25 (whether or not a Business Day) immediately preceding each Interest Payment Date. Interest on the Notes shall 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 September 9, 2021 if no interest has been paid on the Notes), to but not including the next scheduled Interest Payment Date (such payment convention is
referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association). Interest on the Notes shall accrue from September 9, 2021. 

(2)    All payments of principal, Make-Whole Amount, if any, and interest in respect of the Notes, including payments made
upon any redemption of the notes, and Additional Amounts, if any, shall be made in euros. Notwithstanding the first sentence of this clause (2), if the euro is unavailable to the Issuer due to the imposition of exchange controls or other
circumstances beyond the Issuer’s control 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. The amount payable on any date in euro will be converted into U.S.
dollars on the basis of the Market Exchange Rate. Any payment in respect of the Notes so made in U.S. dollars shall not constitute an Event of Default under the Indenture. Neither the Trustee nor the Paying Agent shall be responsible for obtaining
exchange rates, effecting conversions or otherwise handling redenominations. 












 (3)    All payments of principal, Make-Whole Amount, if any, and
interest in respect of Global Notes, including payments made upon any redemption of Notes, and Additional Amounts, if any, shall be made by the Issuer in immediately available funds to the Depository or its nominee, as the case may be, as the Holder
of each of the Global Notes. All payments of principal, Make-Whole Amount, if any, and interest in respect of Notes in certificated form, including payments made upon any redemption of Notes, and Additional Amounts, if any, may be executed at the
office or agency maintained for such purpose in London (initially the Paying Agent Corporate Trust Office) or, at the Issuer’s option, by check mailed to the Holders thereof at the respective addresses set forth in the Security Register,
provided that all payments of principal, Make-Whole Amount, if any, and interest in respect of Notes in certificated form, including payments made upon any redemption of Notes, and Additional Amounts, if any, for which the Holders thereof have given
wire transfer instructions at least ten calendar days prior to the applicable payment date, will be required to be made by wire transfer of immediately available funds to the accounts specified by the Holders thereof. 

(4)    In any case where any Interest Payment Date, Stated Maturity or Maturity of, or any other day on which a payment is
due with respect to, any Notes shall be a day which is not a Business Day, then payment need not be made on such day, but such payment shall be made on the next succeeding day that is a relevant Business Day with the same force and effect as if made
on the Interest Payment Date, at the Stated Maturity or Maturity or on any such other payment date, as the case may be, and no interest shall accrue or be payable on the payment so deferred on such succeeding Business Day for the period from and
after such Interest Payment Date, Stated Maturity, Maturity or other payment date, as the case may be, to such succeeding Business Day. 

(c)    Sinking Fund. There shall be no sinking fund provided for the Notes. 

(d)    Redemption at the Option of the Issuer. 

(1)    The Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a
redemption price (the “Redemption Price”) equal to the greater of (x) 100% of the aggregate principal amount of the Notes being redeemed; and (y) the Make-Whole Amount, if any, plus, in each case, accrued and unpaid interest on
such Notes to, but not including, the Redemption Date. Notwithstanding the foregoing, if the Notes are redeemed on or after June 9, 2030 (the “Par Call Date”), the Redemption Price will equal 100% of the aggregate principal
amount of the Notes being redeemed plus accrued and unpaid interest on such Notes to, but not including, the Redemption Date. 

(2)    The Issuer shall not redeem the Notes pursuant to Section 1.4(d)(1) hereof on any date if the principal
amount of the Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with
respect to the Notes to be redeemed). 












 (3)    With respect to the Notes, the first paragraph of
Section 1104 of the Base Indenture is hereby amended and restated to read as follows: 
 “Notice of redemption shall be given in
the manner provided in Section 106, not less than 15 nor more than 60 days prior to the Redemption Date; provided that while the Notes are represented by one or more Global Notes, notice of redemption may, at the Issuer’s option,
instead be given to the Holders of the Notes (and beneficial interest therein) in accordance with the applicable rules and regulations of Clearstream and Euroclear, and the Issuer will instruct the Trustee and Paying Agent accordingly. Failure to
give notice in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption
of any other Securities or portions thereof.” 
 (e)     Redemption for Tax Reasons. If the Issuer has or
will become obliged to pay Additional Amounts with respect to the Notes pursuant to Section 2.4 of this Eighth Supplemental Indenture as a result of any change in, or amendment to, the laws or regulations of the United States or any political
subdivision or taxing authority thereof or therein, or any change in official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment becomes effective on or after September 2, 2021,
and the Issuer determines that such obligation cannot be avoided by the use of reasonable measures then available to the Issuer, the Issuer may, at its option, at any time, having given not less than 15 nor more than 60 days’ prior written
notice to Holders of the Notes, redeem, in whole, but not in part, the Notes at a redemption price equal to 100% of their principal amount, together with accrued and unpaid interest, if any, on the Notes being redeemed to, but not including, the
Redemption Date; provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts if a payment in respect to the Notes were due on
such date. 
 (f)    Payment of Notes Called for Redemption by the Issuer. 

(1)    If notice of redemption has been given as provided in Article Eleven of the Base Indenture (as amended by this
Eighth Supplemental Indenture) or Section 1.4(e) of this Eighth Supplemental Indenture, the Notes or portion of Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or
places stated in such notice at the Redemption Price, and unless the Issuer shall default in the payment of such Notes at the Redemption Price, so long as the Paying Agent holds funds irrevocably deposited with it sufficient to pay the Redemption
Price of the Notes to be redeemed on the Redemption Date, then (a) such Notes will cease to be Outstanding on and after the date of the deposit, (b) interest on the Notes or portion of Notes so called for redemption shall cease to accrue
on and after the Redemption Date, and (c) the Holders of the Notes being redeemed shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On surrender of such Notes at the place of payment
specified in such notice, the said Notes or the specified portions thereof shall be paid and redeemed by the Issuer at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date. 

(2)    The Notes will not be convertible or exchangeable for any other security or property. 












 (g)    Additional Issues. The Issuer may, from time to time,
without the consent of or notice to the Holders of the Notes, create and issue further notes having the same terms and conditions as the Notes in all respects, except for the issue date and, to the extent applicable, the issue price, the payment of
interest accruing prior to the issue date and the first Interest Payment Date. Additional notes issued in this manner shall be consolidated with, and shall form a single series with, the previously outstanding Notes; provided, however,
that the issuance of such additional notes will not be so consolidated for United States federal income tax purposes unless such issuance constitutes a “qualified reopening” within the meaning of the Internal Revenue Code of 1986, as
amended, and the Treasury regulations promulgated thereunder. 
 (h)    Listing of Notes. The Issuer may, from
time to time, list the Notes on the New York Stock Exchange or another national securities exchange. 

Section 1.5    Book-Entry Provisions. This Section 1.5 shall apply only to the Global Notes deposited
with or on behalf of the Depository. 
 (a)    The Issuer shall execute and the Trustee shall, in accordance with this
Section 1.5 and Section 303 of the Base Indenture, authenticate and deliver the Global Notes that shall be registered in the name of the Common Depository or its nominee and shall be held by the Common Depository or its nominee as
custodian for the Depository. 
 (b)    Participants of the Depository shall have no rights either under the Indenture
or with respect to the Global Notes. The Common Depository or its nominee, as applicable, shall be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner and Holder of each such Global Note for all
purposes under the Indenture. Notwithstanding the foregoing, nothing herein shall prevent the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Common Depository or its nominee, as
applicable, or impair, as between the Depository and its participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in the Global Notes. 

ARTICLE TWO 
 ADDITIONAL COVENANTS
FOR BENEFIT OF HOLDERS OF NOTES 
 In addition to the covenants set forth in the Base Indenture, the Issuer hereby further covenants as
follows, the following covenants being for the sole benefit of the Holders of the Notes: 

Section 2.1    Limitations on Incurrence of Debt. 

(a)    Aggregate Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if,
immediately after giving effect to the incurrence of such Debt and any other Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Debt and the application of the proceeds from such Debt and such
other Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Debt would exceed 65% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate
purchase price of any assets acquired, and the aggregate 












 
amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt),
by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Debt and other securities issued as part of the
same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger). 

(b)    Secured Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Secured
Debt if, immediately after giving effect to the incurrence of such Secured Debt and any other Secured Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Secured Debt and the application of the
proceeds from such Secured Debt and such other Secured Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Secured Debt would exceed 50% of the sum of the following (without duplication): (1) the Issuer’s Total Assets
as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were
not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of
such Secured Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger). 

(c)    Debt Service Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if,
immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the ratio of Adjusted EBITDA to Interest Expense for the four (4) consecutive fiscal quarters ended on the
most recent Reporting Date prior to the incurrence of such Debt would be less than 1.50 to 1.00, and calculated on the following assumptions (without duplication): (1) such Debt and any other Debt incurred since such Reporting Date and outstanding
on the date of determination had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such four-quarter period; (2) the repayment or retirement of any
other Debt since such Reporting Date had occurred on the first day of such four-quarter period; and (3) in the case of any acquisition or disposition by the Issuer or any of its Subsidiaries of any asset or group of assets since such Reporting
Date, whether by merger, stock purchase or sale or asset purchase or sale or otherwise, such acquisition or disposition had occurred as of the first day of such four-quarter period with the appropriate adjustments with respect to such acquisition or
disposition being included in such pro forma calculation. If any Debt incurred during the period from such Reporting Date to the date of determination bears interest at a floating rate, then, for purposes of calculating the Interest Expense, the
interest rate on such Debt will be computed on a pro forma basis as if the average daily rate during such interim period had been the applicable rate for entire relevant four-quarter period. For purposes of the foregoing, Debt will be deemed to be
incurred by a Person whenever such Person creates, assumes, guarantees or otherwise becomes liable in respect thereof. 

(d)    Maintenance of Total Unencumbered Assets. As of each Reporting Date, the Issuer’s Unencumbered Assets
will not be less than 125% of the Issuer’s Unsecured Debt. 












 Section 2.2    Covenant Defeasance and Waiver of Covenant.
The covenants set forth in Section 2.1 shall be subject to covenant defeasance under Section 402(3) of the Base Indenture and subject to waiver under Section 1006 thereof. 

Section 2.3    Merger, Consolidation or Sale. The Issuer may consolidate with or into, or sell, assign,
convey, transfer or lease all or substantially all of its property and assets to, any other entity, provided that: 
  

	 	(1)	 it shall be the continuing entity, or the successor entity (if other than the Issuer) formed by or resulting
from such consolidation or merger or which shall have received such sale, assignment, conveyance, transfer or lease of property and assets shall be an entity domiciled in the United States of America, any state thereof or the District of Columbia
and shall expressly assume by supplemental indenture payment of the principal of and interest on all of the Notes, and the due and punctual performance and observance of all of the covenants and conditions in the Indenture; 



 

	 	(2)	 immediately after giving effect to the transaction and treating the Pro Rata Share of any indebtedness which
becomes the Issuer’s obligation or the obligation of a Subsidiary or any of its unconsolidated joint ventures as a result thereof and is not repaid substantially concurrently with the transaction as having been incurred by the Issuer, that
Subsidiary or that unconsolidated joint venture at the time of the transaction, no Event of Default under the Indenture, and no event which, after notice or the lapse of time, or both, would become an Event of Default, shall have occurred and be
continuing; and 


  

	 	(3)	 an Officer’s Certificate and Opinion of Counsel covering these conditions is delivered to the Trustee.



 Section 2.4    Payment of Additional Amounts. All payments, including payments of
principal, Make-Whole Amount, if any, and interest, made in respect of the Notes will be made free and clear of, and without withholding or deduction (including such deductions and withholdings applicable to Additional Amounts) for, or on account
of, any present or future tax, duty, assessment or other governmental charge of whatever nature imposed, levied or collected by the United States (or any political subdivision or taxing authority thereof or therein), unless such withholding or
deduction is required by law or the official interpretation or administration thereof. The Issuer shall, subject to the exceptions and limitations set forth below, pay as Additional Amounts to a Holder that is a United States Alien such amounts as
may be necessary so that every net payment made in respect of such Note after deduction or withholding for, or on account of, any present or future tax, duty, assessment or other governmental charge of whatever nature imposed, levied or collected as
a result of such payment by the United States (or any political subdivision or taxing authority thereof or therein), will not be less than the amount provided for in such Note to be then due and payable; provided, however, that the
Issuer will not be required to make any payment of Additional Amounts for or on account of: 
 (a) any tax, assessment or other governmental
charge that would not have been imposed but for (i) the existence of any present or former connection (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 hereunder) between such Holder (or between a fiduciary, settlor or beneficiary of, or a person holding a power over, such Holder, if such Holder is an
estate or a trust, or a member or shareholder of such Holder, if such Holder is a partnership or corporation) and the United States, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, person holding a power, member
or shareholder) being or having been a citizen or resident or treated as a resident of the United States or being or having been engaged in trade or business in the United States or having or having had a permanent establishment therein, or
(ii) the presentation by the Holder of the Note for payment more than 30 days after the date on which the payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders of the Notes,
whichever occurs later; 
 (b) any estate, inheritance, gift, sales, transfer, personal property or any similar tax, assessment or other
governmental charge; 
 (c) any tax, assessment or other governmental charge that would not have been imposed but for such Holder’s
past or present status as a controlled foreign corporation, passive foreign investment company (including a qualified electing fund) or foreign private foundation or other tax exempt organization with respect to the United States or as a corporation
that accumulates earnings to avoid United States Federal income tax; 
 (d) any tax, assessment or other governmental charge that is payable
otherwise than by deduction or withholding from a payment on a Note; 
 (e) any tax, assessment or other governmental charge required to be
deducted or withheld by any paying agent from any payment on a Note, if such payment can be made without such deduction or withholding by any other paying agent; 

(f) any tax, assessment or other governmental charge that would not have been imposed but for the Holder’s failure to comply with any
applicable certification, information, documentation or other reporting requirement concerning the nationality, residence, identity or connection with the United States of the Holder or beneficial owner of a Note if, without regard to any tax
treaty, such compliance is required by statute or regulation of the United States as a precondition to relief or exemption from such tax, assessment or other governmental charge; 

(g) any tax, assessment or other governmental charge imposed by reason of the Holder (i) owning or having owned, directly or indirectly,
actually or constructively, 10% or more of the total combined voting power of all classes of stock of the Issuer entitled to vote, (ii) receiving interest described in Section 881(c)(3)(A) of the United States Internal Revenue Code or
(iii) being a controlled foreign corporation with respect to the United States that is related to the Issuer by actual or constructive stock ownership; 

(h) any tax, assessment or other governmental charge that is imposed on a payment pursuant to Sections 1471 through 1474 of the United States
Internal Revenue Code (FATCA), any Treasury regulations and official interpretations thereof, and any regulations or official law, agreement or interpretations thereof implementing an intergovernmental approach thereto; or 

(i) any combination of items (a), (b), (c), (d), (e), (f), (g) and (h); 












 nor shall such Additional Amounts be paid with respect to any payment on a Note to a Holder that is a
fiduciary or partnership or other than the sole beneficial owner of such payment to the extent a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner would not have been entitled to the
Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Note. 
 For purposes of the foregoing,
the holding of or the receipt of any payment with respect to a Note shall not constitute a connection between the Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of, or a person having power over, such Holder if such
Holder is an estate, a trust, a partnership or a corporation) and the United States. 
 Whenever in the Indenture (including the Notes)
there is referenced, in any context, the payment of amounts based on the payment of principal of, or premium, if any, or interest on, the Notes, or any other amount payable thereunder or with respect thereto, such reference will be deemed to include
the payment of Additional Amounts as described under this Section 2.4 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. The Additional Amounts as defined above shall constitute
“Additional Amounts” for purposes of the Base Indenture. 
 ARTICLE THREE 

TRUSTEE AND AGENTS 

Section 3.1    Agents. Elavon Financial Services DAC, UK Branch, shall be the initial Paying Agent for the

any such other obligor). The Trustee is permitted to engage in other transactions with the Issuer and its Affiliates. If, however, it acquires any conflicting interest under the Trust Indenture
Act relating to any of its duties with respect to the Notes, it must eliminate that conflict or resign, subject to its right under the Trust Indenture Act to seek a stay of its duty to resign. 

Section 3.4    Calculation with Respect to the Notes. The Issuer shall be responsible for making all

Trustee and the Holders of the Notes. The Issuer shall provide a schedule of its calculations to the Trustee promptly after it makes such calculations, and the Trustee shall be entitled to rely upon the accuracy of the Issuer’s calculations

 REVERSE SIDE OF NOTE 

PUBLIC STORAGE 
 0.500%
SENIOR NOTE DUE 2030 
 This Note is one of a duly authorized issue of Notes of the Issuer, designated as its 0.500% Senior Notes due 2030 (herein
called the “Notes”), issued under and pursuant to an Indenture dated as of September 18, 2017 (herein called the “Base Indenture”), between the Issuer and Wells Fargo Bank, National Association, as trustee
(herein called the “Trustee”), as supplemented by the Eighth Supplemental Indenture dated as of September 9, 2021 (herein called the “Eighth Supplemental Indenture,” and together with the Base Indenture, the
“Indenture”), between the Issuer and the Trustee, to which Indenture and any 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 of the Notes. Defined terms used but not otherwise defined in this Note shall have the respective meanings ascribed thereto in the Indenture. 

The Issuer shall have the option to redeem the Notes at any time in whole, or from time to time in part, at a redemption price (the “Redemption
Price”) equal to the greater of: (x) 100% of the aggregate principal amount of the Notes being redeemed; and (y) the Make-Whole Amount, if any, plus, in each case, accrued and unpaid interest on such Notes to, but not including,
the Redemption Date. If the Notes are redeemed on or after the Par Call Date, the Redemption Price will not include the Make-Whole Amount. Notwithstanding the foregoing, if the Notes are redeemed on or after June 9, 2030, the redemption price
will equal 100% of the aggregate principal amount of the Notes being redeemed plus accrued and unpaid interest on such Notes to, but not including, the Redemption Date. 

All payments, including payments of principal, Make-Whole Amount, if any, and interest, made in respect of the Notes will be made free and clear of, and
without withholding or deduction (including such deductions and withholdings applicable to Additional Amounts) for, or on account of, any present or future tax, duty, assessment or other governmental charge of whatever nature imposed, levied or
collected by the United States (or any political subdivision or taxing authority thereof or therein), unless such withholding or deduction is required by law or the official interpretation or administration thereof. The Issuer will pay as additional
amounts (“Additional Amounts”) to a Holder that is a United States Alien such amounts as may be necessary so that every net payment made in respect of such Note after deduction or withholding for, or on account of, any present or
future tax, duty, assessment or other governmental charge of whatever nature imposed, levied or collected as a result of such payment by the United States (or any political subdivision or taxing authority thereof or therein), will not be less than
the amount provided for in such Note to be then due and payable; provided, however, that the Issuer will not be required to make any payment of Additional Amounts to the extent of an exception provided for in Section 2.4 of the
Eighth Supplemental Indenture applies. 
 If the Issuer has or will become obliged to pay Additional Amounts with respect to the Notes as a result of any
change in, or amendment to, the laws or regulations of the United States or any political subdivision or taxing authority thereof or therein, or any change in official position regarding the application or interpretation of such laws, regulations or
rulings, which change or 

  
 A-5 













 
amendment becomes effective on or after September 2, 2021, and the Issuer determines that such obligation cannot be avoided by the use of reasonable measures then available to the Issuer,
the Issuer may, at its option, at any time, having given not less than 15 nor more than 60 days’ prior written notice to Holders of the Notes, redeem, in whole, but not in part, the Notes at a redemption price equal to 100% of their principal
amount, together with accrued and unpaid interest, if any, on the Notes being redeemed to, but not including, the Redemption Date; provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on
which the Issuer would be obliged to pay such Additional Amounts if a payment in respect to the Notes were due on such date. 
 The Issuer shall not redeem
the Notes pursuant to Section 1.4(d)(1) of the Eighth Supplemental Indenture on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the
case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Notes to be redeemed). 
 If an
Event of Default (other than an Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all Notes may be
declared to be due and payable by either the Trustee or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding, and, upon said declaration the same shall be immediately due and payable. If an
Event of Default specified in Section 501(5), 501(6) or 501(7) of the Base Indenture occurs, the principal of and premium, if any, and interest accrued and unpaid on all the Notes shall be immediately and automatically due and payable
without necessity of further action. 
 The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less
than a majority in aggregate principal amount of the Notes at the time outstanding, 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 with respect to the Notes or modifying in any manner the rights of the Holders of the Notes, subject to exceptions set forth in Section 902 of the Base Indenture. Subject to the provisions of the Indenture, the Holders of not less
than a majority in aggregate principal amount of the Notes at the time outstanding may, on behalf of the Holders of all of the Notes, waive any past default or Event of Default with respect to the Notes, subject to exceptions set forth in the
Indenture. 
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Issuer and the Holder of the
Notes, the obligation of the Issuer, which is absolute and unconditional, to pay the principal of, premium, if any, on and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the
Indenture prescribed. 
 Interest on the Notes shall be computed on the basis 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 September 9, 2021 if no interest has been paid on the Notes), to but not including the next scheduled interest payment date (such payment
convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association). 

  
 A-6 













 The Notes are issuable in fully registered form, without coupons, in minimum denominations of €100,000
principal amount and any multiple of €1,000 in excess thereof. At the office or agency of the Issuer referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service
charge but with payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, Notes may be transferred or may be exchanged for a like
aggregate principal amount of Notes of any other authorized denominations. 
 The Issuer shall have the right to redeem the Notes under certain
circumstances as set forth in Section 1.4(d) and Section 1.4(e) of the Eighth Supplemental Indenture and Article Eleven of Base Indenture. 
 The
Notes are not subject to redemption through the operation of any sinking fund. 
 Except to the extent expressly provided in Article Sixteen of the
