from time to time; provided that if, as of a particular date as of which compliance with the covenants contained in the Indenture is being determined, there have been changes in accounting principles generally accepted in the United States of
America from those that applied to the Issuer’s consolidated financial statements included in the Quarterly Report on Form 10-Q for the quarter ended June 30, 2017, the Issuer may, in its sole

in respect of each dollar if the redemption had been made on the Par Call Date (determined by discounting, on a semi-annual basis, the principal and interest at the Reinvestment Rate, determined on the third Business Day preceding the date notice of

“Marketable Securities” means: (a) common or preferred Equity Interests which are listed on Nasdaq or have trading
privileges on the New York Stock Exchange, the NYSE American, or another recognized national United States securities exchange, the London Stock Exchange, Euronext or another recognized European securities exchange; (b) convertible securities

except as otherwise specified in this Second Supplemental Indenture, so long as any of PS Business Parks and Shurgard Europe is not a Subsidiary of the Issuer, the calculations of such figures or measures shall exclude the impact of any such entity
that is not a Subsidiary. 
 “Property” means a parcel (or group of related parcels) of real property. 

“Property EBITDA” means, for any period, the Issuer’s Pro Rata Share of EBITDA for such period adjusted to add back the

“Reinvestment Rate” means the yield on treasury securities at a constant maturity corresponding to the remaining life to
maturity (rounded up to the nearest month) of the principal of the Notes being redeemed as of the date of redemption (which maturity shall be deemed to be the Par Call Date) (the “Treasury Yield”), plus 0.15%. For purposes of
calculating the 

  
 5 













 
Reinvestment Rate, the Treasury Yield will be equal to the arithmetic mean of the yields published in the Statistical Release under the heading “Week Ending” for “U.S. Government
Securities—Treasury Constant Maturities” with a maturity equal to the deemed remaining life to maturity of the Notes. However, if no published maturity exactly corresponds to such remaining life, then the Treasury Yield will be
interpolated or extrapolated on a straight-line basis from the arithmetic means of the yields for the next shortest and next longest published maturities. For purposes of calculating the Reinvestment Rate, the most recent Statistical Release
published prior to the date of determination of the Make-Whole Amount will be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury Yield in the above manner, then the Treasury
Yield will be determined in the manner that most closely approximates the above manner, as the Issuer reasonably determines. 

“Reporting Date” means the date ending the most recently ended fiscal quarter of the Issuer for which the Issuer’s
consolidated financial statements are publicly available, it being understood that at any time when the Issuer is not subject to the informational requirements of the Exchange Act, the term “Reporting Date” shall be deemed to refer to the
date ending the fiscal quarter covered by the Issuer’s most recent quarterly financial statements delivered to the Trustee or, in the case of the last fiscal quarter of the year, the Issuer’s annual financial statements delivered to the
Trustee. 
 “Secured Debt” means Debt secured by any mortgage, lien, pledge, encumbrance or security interest of any kind
upon any of the Issuer’s Property or other assets or the Property or other assets of any Subsidiary. 
 “Shurgard
Europe” means Shurgard Self Storage SA and its Subsidiaries and their respective successors and assigns. 
 “Statistical
Release” means the statistical release designated “H.15” or any successor publication that is published weekly by the Federal Reserve System (or companion online data resource published by the Federal Reserve System) and that
reports yields on actively traded United States government securities adjusted to constant maturities, or, if that statistical release is not published at the time of any required determination under the Indenture, then another reasonably comparable
index which the Issuer shall designate. 
 “Subsidiary” means, for any Person, a corporation, partnership, joint venture,
limited liability company or other entity, a majority of the outstanding voting stock, partnership interests or membership interests, as the case may be, of which is owned or controlled, directly or indirectly, by such Person or by one or more other
Subsidiaries of such Person and, for the purposes of this definition, “voting stock, partnership interests, or membership interests” means interests having control over the selection of directors, managers, or trustees, as the case may be,
whether at all times or only so long as no senior interest has such voting power by reason of any contingency. Unless the context otherwise requires, “Subsidiary” refers to a Subsidiary of the Issuer. Notwithstanding the foregoing, none of
the Persons comprising PS Business Parks or Shurgard Europe shall at any time constitute or be considered to be a Subsidiary of the Issuer for any purpose of the Indenture so long as (a) any class of Equity Interests of the applicable holding

Rata Share of the current undepreciated book value of Development Properties and all land held for development; (d) the Pro Rata Share of the purchase price paid by the Issuer or any Subsidiary (less the Pro Rata Share of any amounts paid to
the Issuer or such Subsidiary as a purchase price adjustment, held in escrow, retained as a contingency reserve, or in connection with other similar arrangements, and without regard to allocations of property purchase prices pursuant to Statement of
Financial Accounting Standards No. 141 or other provisions of GAAP) for any Property or business acquired by the Issuer or such Subsidiary during the four (4) consecutive quarters ending on such date; (e) the contractual purchase
price of Properties of the Issuer and its Subsidiaries subject to purchase obligations, repurchase obligations, forward commitments and unfunded obligations to the extent such obligations and commitments are included in determinations of Debt; and
(f) the Fair Market Value of all Marketable Securities owned by the Issuer or any of its Subsidiaries, plus all other assets of the Issuer and its Subsidiaries (the value of which is determined in accordance with GAAP but excluding assets
classified as intangible under GAAP), excluding Equity Interests in Shurgard Europe or PS Business Parks if such interests are not Marketable Securities. The Issuer shall have the option to include Capitalized Property Value under clause
(a) above from any such Properties that are otherwise subject to valuation under clause (c) or (d) above; provided, however, that if such election is made, any value attributable to such Properties under clause (c) or
(d) above shall be excluded from the determination of the amount under clause (c) or (d). 
 “Unencumbered Assets”
means, as of any date, Total Assets as of such date less Encumbered Asset Value as of such date. 
 “Unsecured Debt” means
Debt that is not secured by any mortgage, lien, pledge, encumbrance or security interest of any kind upon any of the Issuer’s Property or other assets or the Property or other assets of any Subsidiary. 

Section 1.2 Creation of the Notes. In accordance with Section 301 of the Base Indenture, the Issuer hereby creates the Notes
as a separate series of its senior debt securities, entitled “3.385% Senior Notes due 2029”, issued pursuant to the Indenture. The Notes shall initially be limited to an aggregate principal amount equal to $500,000,000, subject to the
exceptions set forth in Section 301(2) of the Base Indenture and Section 1.4(f) hereof. 
 Section 1.3
Form of the Notes. The Notes will be issued in the form of one or more permanent fully registered global securities (the “Global Note”) that will be deposited with, or on behalf of the Depository, and
registered in the name of the Depository or its nominee, as the case may be, subject to Section 305 of the Base Indenture. So long as the Depository, or its nominee, is the registered owner of the Global Note, the Depository or its nominee, as
the case may be, will be considered the sole Holder of the Notes represented by the Global Note for all purposes under the Indenture.

 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 Second 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 $2,000 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. All payments of principal, Make-Whole Amount, if any, and interest in respect of the Global
Notes will 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. The Notes shall mature, and the unpaid principal thereon, shall be payable, on
May 1, 2029, subject to the provisions of the Base Indenture. The rate per annum at which interest shall be payable on the Notes shall be 3.385%. Interest on the Notes will be payable semi-annually in arrears on each May 1 and
November 1, commencing November 1, 2019 (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 April 15 for Interest Payment Dates of May 1 and October 15 for Interest Payment Dates of November 1 (in each case, whether or not a Business Day) (each a
“Record Date”). Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. Interest on the Notes shall accrue from
April 12, 2019. 
 (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 sum of (x) the principal amount of the Notes being redeemed plus accrued and unpaid interest on such Notes to the Redemption Date; and (y) the Make-Whole Amount, if any. If the Notes are
redeemed on or after February 1, 2029 (the “Par Call Date”), the Redemption Price will not include the Make-Whole Amount. 

(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). 
 (e) 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, 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 

  
 8 













 
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. 
 (f) 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. 
 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 Depository or its nominee and shall be held by the Trustee 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 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 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 

  
 10 













 
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 legal opinion covering these conditions is delivered to the Trustee.

 REVERSE SIDE OF NOTE 

PUBLIC STORAGE 
 3.385%
SENIOR NOTE DUE 2029 
 This Note is one of a duly authorized issue of Notes of the Issuer, designated as its 3.385% Senior Notes due 2029 (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 Second Supplemental Indenture dated as of April 12, 2019 (herein called the “Second 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 equal to the sum of
(x) the principal amount of the Notes being redeemed plus accrued and unpaid interest on such Notes to the Redemption Date; and (y) the Make-Whole Amount, if any. If the Notes are redeemed on or after the Par Call Date, the Redemption
Price will not include the Make-Whole Amount. 
 The Issuer shall not redeem the Notes pursuant to Section 1.4(d)(1) of the Second 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. 

  
 A-5 













 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 of a
360-day year of twelve 30-day months. 
 The Notes are issuable in fully
registered form, without coupons, in minimum denominations of $2,000 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) of the Second 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 Base Indenture, no recourse for the payment of the principal of or any premium 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 Issuer in the Indenture or any supplemental indenture or in any Note, or because of the
creation of any indebtedness represented thereby, shall be had against any past, present or future general partner, limited partner, member, employee, incorporator, controlling person, stockholder, officer, director or agent, as such, of the Issuer
or of any of the Issuer’s predecessors or successors, either directly or through the Issuer, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the acceptance of the Notes by the Holders thereof and as part of the consideration for the issue of the Notes.
