Section 2.1. Indenture. The changes, modifications and supplements to the Indenture effected by this Supplemental Indenture shall
be applicable only with respect to, and shall only govern the terms of, the Notes that may be issued from time to time, and shall not apply to any other Securities that may be issued under the Indenture unless an Officers’ Certificate or
supplemental indenture with respect to such other Securities specifically incorporates such changes, modifications and supplements. The provisions of this Supplemental Indenture shall supersede any conflicting provisions in the Indenture with
respect to the Notes.

transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 3.04, 3.05, 3.06, 9.06 or 11.07 of the Base Indenture and any Notes that, pursuant to Section 3.03 of the Base Indenture, are deemed never to have been
authenticated and delivered, and subject to the Company’s ability to issue Additional Notes pursuant to Section 2.6.

Indenture, for the benefit of the Holders of the Notes but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, Section 4.01 of the Base Indenture is amended and restated in its entirety as
follows with respect to the Notes: 
 (a) The Indenture will be discharged as to all Notes and will cease to be of further effect as to all
Notes, when either:

have been replaced or paid and Notes for whose payment money has been deposited in trust) have been delivered to the Trustee for cancellation; or 

(ii) (A) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the
giving of a notice of redemption or otherwise, will become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the
name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee, as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, U.S. Government Obligations, or a
combination thereof, in such amounts as will be sufficient to pay and discharge the entire indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of
maturity or redemption, as the case may be; (B) no Default or Event of Default has occurred and is continuing on the date of such deposit or will occur as a result of such deposit (other than a Default or an Event of Default resulting from the
borrowing of funds to be applied to make such deposit and any similar and simultaneous deposit relating to other indebtedness and, in each case, the granting of Liens in connection therewith) and the deposit will not result in a breach or violation
of, or constitute a default under, any material agreement or material instrument (other than the Indenture) to which the Company is a party or by which the Company is bound; (C) the Company has paid or caused to be paid all sums payable or due
and owing by the Company under the Indenture; and (D) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the Redemption Date, as the case may be. 

(b) In addition, the Company shall deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of Counsel
may be subject to customary assumptions and exclusions) stating that all conditions precedent to satisfaction and discharge have been satisfied. 

(c) Notwithstanding the satisfaction and discharge of the Indenture, the obligations of the Company to the Trustee under Section 6.07 of
the Base Indenture, the obligations of the Trustee to any Authenticating Agent under Section 6.14 of the Base Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (ii)(A) of clause (a) of this
Section 3.1, the obligations of the Trustee under Section 4.02 of the Base Indenture and the last paragraph of Section 10.03 of the Base Indenture shall survive.

 Section 5.1. Limitation on Liens. The Company will not, and will not permit any Subsidiary to,
at any time pledge or otherwise subject to any Lien any of its or such Subsidiary’s property, tangible or intangible, real or personal (hereinafter “property”), without thereby expressly securing the Notes (together, if the Company so

 Section 5.2. Release of Liens. Any Lien that is granted to secure the
Notes pursuant to Section 5.1 shall be automatically released and discharged at the same time as the release (other than through the exercise of remedies with respect thereto) of each Lien that gave rise to such obligation to secure the
Notes under Section 5.1. 
 Section 5.3. Merger, Consolidation or Sale of All or Substantially All Assets. Except as may be
provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, Section 8.01 of the Base Indenture is hereby

Company”) is a Person organized and existing under the laws of the United States of America, any state or territory thereof or the District of Columbia; 

(ii) the Successor Company (if other than the Company) expressly assumes all of the obligations of the Company under the Notes

Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and the Notes; provided, that in the case of a lease of all or substantially all its assets, the Company will not be
released from the obligation to pay the principal of and interest on the Notes.

ARTICLE 6 
 DEFAULTS AND
REMEDIES 
 Section 6.1. Events of Default. Except as may be provided in a Future Supplemental Indenture, for the benefit of
the Holders of the Notes but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, Section 5.01 of the Base Indenture is hereby amended and restated in its entirety as follows with respect to the
Notes by this Section 6.1: 
 Each of the following is an “Event of Default”: 

(a) default in any payment of interest on any Note when due, which default continues for a period of 30 days; 

(b) default in the payment of principal of, or premium, if any, on any Note when due at its Stated Maturity, upon optional redemption, upon
required repurchase, upon declaration or otherwise; 
 (c) default in the performance, or breach, of any covenant or warranty of the Company
in the Indenture with respect to the Notes (other than a covenant or warranty with respect to which a default in performance or breach is elsewhere in this Section 6.1 specifically addressed or which covenant or warranty has been included in
the Indenture solely for the benefit of one or more series of notes other than the Notes), and continuance of such default or breach for a period of 90 consecutive days after there has been given, by registered or certified mail, to the Company by
the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Notes, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a
“Notice of Default” under the Indenture; 
 (d) default under any mortgage, indenture (including the Indenture) or instrument
under which there is issued, or which secures or evidences, any indebtedness for borrowed money of the Company (or the payment of which is guaranteed by the Company) (other than indebtedness owed to any Subsidiary or
Non-Recourse Indebtedness of the Company) now existing or hereafter created, which default shall constitute a failure by the Company to pay principal in an amount exceeding $200.0 million (the
“Threshold Amount”) when due and payable by the Company at final stated maturity, after expiration of any applicable grace period with respect thereto (such default, a “payment default”), or shall have resulted in an aggregate
principal amount of such indebtedness exceeding the Threshold Amount becoming due and payable by the Company prior to the date on which it would otherwise have become due and payable (such default, an “acceleration default”);
provided, however, that in connection with any series of the Convertible Notes, (i) any conversion of such indebtedness by a holder thereof into shares of common stock, cash or a combination of cash and shares of common stock,
(ii) the rights of holders of such indebtedness to convert into shares of common stock, cash or a combination of cash and shares of common stock and (iii) the rights of holders of such indebtedness to require any repurchase by the Company
of such indebtedness in cash upon a fundamental change shall not, in itself, constitute an Event of Default hereunder; or 
 (e) 

(i) the Company, pursuant to or within the meaning of any Bankruptcy Law: (A) commences proceedings to be adjudicated
bankrupt or insolvent; (B) consents to the institution of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking an arrangement of debt, reorganization, dissolution, winding up or relief
under applicable 

  
 11 

 
Bankruptcy Law; (C) consents to the appointment of a receiver, interim receiver, receiver and manager, liquidator, assignee, trustee, sequestrator or other similar official of it or for all
or substantially all of its property; (D) makes a general assignment for the benefit of its creditors; or (E) makes an admission in writing of its inability to pay its debts generally as they become due; or 

(ii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against
the Company in a proceeding in which the Company is to be adjudicated bankrupt or insolvent; (B) appoints a receiver, interim receiver, receiver and manager, liquidator, assignee, trustee, sequestrator or other similar official of the Company;
or (C) orders the liquidation, dissolution or winding up of the Company; and the order or decree remains unstayed and in effect for 90 consecutive days (any such Event of Default specified in this clause (e), for purposes of the Notes, shall
constitute a “Bankruptcy Default”). 
 Within 60 days following the date on which the Company becomes aware of a Default or
receives notice of such Default, as applicable, if such Default is continuing, the Company shall deliver a certificate to the Trustee specifying any events which would constitute a Default, their status and what action the Company is taking or
proposing to take in respect thereof. 
 In the event of a declaration of acceleration of the Notes solely because an Event of Default
described in Section 6.1(d) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if (i) the default or defaults triggering such Event of Default pursuant to
Section 6.1(d) shall be remedied or cured by the Company or waived by the holders of the relevant indebtedness within 30 days after the declaration of acceleration with respect thereto; (ii) the rescission and annulment of the
acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction; and (iii) all Events of Default with respect to Notes, except non-payment of principal of, or
premium, if any, or interest on, the Notes that have become due solely by such declaration of acceleration of the Notes of such series, have been cured or waived as provided in the Indenture. 

Section 6.2. Acceleration. 

(a) Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of
Securities under the Indenture, whether now or hereafter issued and Outstanding, the first three paragraphs of Section 5.02 of the Base Indenture are hereby replaced with the following with respect to the Notes: 

“If an Event of Default (other than an Event of Default described in Section 6.1(e) of the Supplemental Indenture) occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable by
notice in writing to the Company (and to the Trustee if given by Holders). Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest, if any, will be due and payable immediately. 

If an Event of Default described in Section 6.1(e) occurs and is continuing, the principal of, premium, if any, and accrued and
unpaid interest, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.” 

(b) Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of
Securities under the Indenture, whether now or hereafter issued and Outstanding, the fourth paragraph of Section 5.02 of the Base Indenture is hereby amended by replacing the period at the end of clause (b) thereof with “; and”
and adding the following clause (c) thereafter: “(c) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction.” 

Section 6.3. Control by Holders. Notwithstanding Section 5.12 of the Base Indenture, the Trustee may refuse to follow any
direction that conflicts with any law, rule, regulation or court order or the Indenture or the Notes, or that the Trustee determines in good faith is unduly prejudicial to the rights of any Holder or that would 

  
 12 

 
involve the Trustee in personal liability. Any application by the Trustee for written instructions from the requisite amount of Holders may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under the Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the
Trustee in accordance with a proposal included in such application on or after the date specified in such application unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written
instructions from the requisite amount of Holders in response to such application specifying the action to be taken or omitted. 

Section 6.4. Waivers. It shall not be necessary for any Act of Holders to approve the particular form of any waiver,
but it shall be sufficient if such Act shall approve the substance thereof. A consent to any waiver by any Holder given in connection with a sale, tender or exchange of such Holder’s Notes will not be rendered invalid by such sale,
tender or exchange. 
 ARTICLE 7 

DEFEASANCE 

Section 7.1. Covenant Defeasance. The covenants provided pursuant to Section 3.01(r), 9.01(b) or 9.01(g) of the

ARTICLE 8 
 REPURCHASE OF
NOTES AT OPTION OF HOLDERS 
 Section 8.1. Offer to Repurchase Upon Change of Control Repurchase Event. 

(a) If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem all of the Notes pursuant to
Section 9.1 of this Supplemental Indenture, the Company will make an offer to purchase all the Notes (the “Change of Control Offer”) at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and
unpaid interest, if any, to the date of purchase (the “Change of Control Payment”). If a Note is repurchased pursuant to a Change of Control Offer on or after a Regular Record Date but on or prior to the related Interest Payment Date, then
any accrued and unpaid interest shall be paid to the holder of record as of such Regular Record Date. Within 30 days following the date upon which a Change of Control Repurchase Event occurred, or at the Company’s option, prior to any Change of
Control but after the public announcement of the pending Change of Control, unless the Company has exercised its right to redeem all of the Notes pursuant to Section 9.1 of this Supplemental Indenture, the Company will mail a notice of such
Change of Control Offer to each Holder or otherwise give notice, which will govern the terms of the Change of Control Offer, in accordance with the applicable procedures of DTC, with a copy to the Trustee, stating: 

(i) that a Change of Control Offer is being made pursuant to this Section 8.1 and that all Notes validly tendered pursuant
to such Change of Control Offer will be accepted for purchase by the Company at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase; 

(ii) the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed or
given, other than as may be required by law) (the “Change of Control Payment Date”); 
 (iii) if sent prior to the
date of consummation of the Change of Control, that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date; provided, that if a Change of Control is consummated
after a proposed Change of Control Payment Date and such Change of Control Offer is therefore not consummated, the Company shall make a Change of Control Offer in accordance with this Section 8.1 within 30 days following the later of the
consummation of such Change of Control or a Below Investment Grade Rating Event; 

  
 13 

 (iv) that Notes must be tendered in multiples of $1,000, and any Note not
validly tendered will remain outstanding and continue to accrue interest; 
 (v) that, unless the Company defaults in the
payment of the Change of Control Payment, any Note accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on and after the Change of Control Payment Date; 

(vi) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such
Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice, or transfer their Notes to the Paying Agent by
book-entry transfer pursuant to the applicable procedures of the Paying Agent, prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 

(vii) that Holders shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase
such Notes; provided, that the Paying Agent receives at the address specified in the notice, not later than the close of business on the 30th day following the date of the Change of Control notice, a telegram, facsimile transmission or letter
setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased; 

(viii) that if a Holder is tendering less than all of its Notes, such Holder will be issued new Notes equal in principal amount
to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to $2,000 or an integral multiple of $1,000 in excess thereof); and 

(ix) the other instructions, as determined by the Company, consistent with this Section 8.1 that a Holder must follow.

 The notice, if mailed or given in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder
receives such notice. If (A) the notice is mailed or given in a manner herein provided and (B) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice
or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect. 

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

(i) accept for payment all Notes or portions of Notes (of integral multiples of $1,000) validly tendered pursuant to the Change
of Control Offer; 
 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all
Notes or portions of Notes so tendered; 
 (iii) deliver or cause to be delivered to the Trustee for cancellation the Notes
so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company in accordance with this Section 8.1; and 

(iv) deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent
provided for in the Indenture relating to the making of such Change of Control Payment have been complied with. 
 (c) The Paying Agent will
promptly pay to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate, upon receipt of an authentication order, and mail (or cause to be transferred by book entry) to each Holder a
new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof. 

  
 14 

 (d) If the Change of Control Payment Date is on or after a Regular Record Date and on or
before the related Interest Payment Date, any accrued and unpaid interest to the Change of Control Payment Date will be paid on the relevant Interest Payment Date to the Person in whose name a Note is registered at the close of business on such
Regular Record Date. 
 (e) Prior to making a Change of Control Payment, and as a condition to such payment (i) the requisite holders
of each issue of indebtedness issued under an indenture or other agreement that would be violated by the making of such payment shall have consented to such Change of Control Payment being made and waived the event of default, if any, caused by the
Change of Control or (ii) the Company will repay all outstanding indebtedness issued under an indenture or other agreement that would be violated by the making of a Change of Control Payment or the Company will offer to repay all such
indebtedness, make payment to the holders of such indebtedness that accept such offer and obtain waivers from the requisite remaining holders of such indebtedness of any event of default arising under the relevant indenture or other agreement as a
result of the Change of Control. The Company covenants to effect such repayment or obtain such consent prior to making a Change of Control Payment, it being a default of this Section 8.1 if the Company fails to comply with such covenant. 

(f) The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 8.1 applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such
Change of Control Offer. 
 (g) The Company will comply, to the extent applicable, with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any
securities laws or regulations conflict with provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Indenture by virtue of the
conflict. 
 (h) Other than as specifically provided in this Section 8.1, any purchase pursuant to this Section 8.1 shall be made
pursuant to the provisions of Sections 11.03, 11.05 and 11.07 of the Base Indenture. 
 (i) Notwithstanding anything to the contrary in the
foregoing clauses (a) though (h), the Company’s obligation to make a Change of Control Offer may, subject to Section 4.2(b) of this Supplemental Indenture, be waived or modified with the written consent of the Holders of a
majority in principal amount of the Notes. 
 ARTICLE 9 

OPTIONAL REDEMPTION 

Section 9.1. Optional Redemption.  

(a) At any time prior to January 15, 2022, the Company may redeem the Notes at its option, in whole or in part, upon notice pursuant to
Section 11.04 of the Base Indenture, at a Redemption Price equal to 100% of the aggregate principal amount of the Notes plus the Applicable Premium, plus accrued and unpaid interest, if any, to the Redemption Date. Promptly after the
determination thereof, the Company shall give the Trustee written notice of the Redemption Price provided for in this Section 9.1(a), and the Trustee shall not be responsible for such calculation. If a Note is redeemed on or after a Regular
Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the holder of record as of such Regular Record Date. Unless the Company defaults in payment of the Redemption Price, from and
after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption. 
 (b) Except pursuant to
clause (a) of this Section 9.1, the Notes shall not be redeemable at the Company’s option prior to January 15, 2022. 

  
 15 

 (c) Any redemption pursuant to this Section 9.1 shall be made pursuant to the
provisions of Sections 11.01 through 11.07 of the Base Indenture; provided, that the words “by such method as the Trustee shall deem fair and appropriate and” in Section 11.03 of the Base Indenture shall be replaced with
“by lot.” 
 (d) Any redemption notice may, at the Company’s discretion, be subject to one or more conditions precedent,
including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Company’s discretion, the Redemption Date may be delayed until such
time as any or all such conditions shall be satisfied or waived (provided that in no event shall such Redemption Date be delayed to a date later than 60 days after the date on which such notice was given), or such redemption may not occur and such
notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the Redemption Date, or by the Redemption Date as so delayed. 

(e) The Company may acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or
otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture. 

Section 9.2. Modification of Base Indenture. Except as may be provided in a Future Supplemental Indenture, for the benefit of the
Holders of the Notes but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, Section 11.06 of the Base Indenture is hereby amended by deleting the words “Record Dates” and
replacing them with “Regular Record Date.”

Decreases in Global Security attached hereto)

 AIR LEASE CORPORATION, a corporation duly organized and existing under the laws of the State of Delaware
(herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., the registered Holder hereof, the principal sum of
[    ] Dollars ($[    ]) (as revised by the Schedule of Increases and Decreases in Global Security attached hereto) on January 15, 2022 and to pay interest thereon from and including
September 17, 2018 or from and including the most recent date to which interest has been paid or duly provided for, semi-annually on January 15 and July 15 in each year, commencing January 15, 2019 (each an “Interest Payment
Date”), at the rate of 3.500% per annum (the “Interest Rate”), until the principal hereof is paid or made available for payment; provided that any principal, and any such installment of interest, that is overdue shall bear
interest at the Interest Rate (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand. If any
Interest Payment Date, Redemption Date or Stated Maturity of a Note is not a Business Day, the payment otherwise required to be made on such date may be made on the next Business Day with the same force and effect as if made on such Interest Payment
Date, Redemption Date or Stated Maturity, as the case may be, and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, which shall be the January 1 or July 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest so payable but not so punctually paid or duly
provided for on any Interest Payment Date will forthwith cease to be payable to the Holder on such Regular Record Date and, at the Company’s election, may either be paid to the Person in whose name this Note (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof to be given to Holders of Notes not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in such
Indenture. 

 Payment of the principal of and interest on this Note will be made at the office or agency
of the Company maintained for that purpose in The City of New York, New York (or, if the Company does not maintain such office or agency, at the corporate trust office of the Trustee in The City of New York or if the Trustee does not maintain an
office in The City of New York, at the office of a Paying Agent in The City of New York), in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided,
however, that payment of principal and interest on Global Securities shall be made by wire transfer in accordance with the procedures of the Depositary. 

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature of one or more authorized signatories, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 

 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

 [REVERSE OF NOTE] 

This Note is one of a duly authorized series of securities of the Company designated as the “3.500% Senior Notes due 2022” (herein
called the “Notes”), issued under an Indenture, dated as of October 11, 2012 (herein called the “Base Indenture”), as supplemented by the Nineteenth Supplemental Indenture dated as of September 17, 2018 (the
“Nineteenth Supplemental Indenture”; the Base Indenture, as so supplemented, is herein called the “Indenture”), among the Company, as issuer, and Deutsche Bank Trust Company Americas, as Trustee (herein called the
“Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, initially limited in aggregate principal amount to
$700,000,000. The Company may at any time issue Additional Notes under the Indenture in unlimited amounts having the same terms as the Notes, except as otherwise permitted by the Indenture. 

The Notes do not have the benefit of any sinking fund obligation. 

The Notes are redeemable prior to the Stated Maturity Date as provided in the Indenture. In the event of redemption of this Note in part only,
a new Note or Notes in an authorized denomination for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Note or of certain restrictive covenants and
Events of Default with respect to the Notes, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event
of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 

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

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture or this Note, or for the appointment of a receiver or trustee or for any other remedy thereunder, unless (i) an Event of Default has occurred and is continuing and the Holder of this Note has
previously given written notice to the Trustee of such Event of Default and the continuance thereof, (ii) the Holders of not less than 25% in principal amount of the Outstanding Notes have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee hereunder, (iii) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred in compliance with such request, (iv) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding, and (v) no direction inconsistent with such written
request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of
this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 

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

 As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Note are payable,
duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or the Holder’s attorney duly authorized in writing, and thereupon one or
more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Indenture and this Note are governed by and construed in accordance with the laws of the State of New York. 

The Notes are issuable in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess
thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of any authorized denomination, as requested by the Holder surrendering the same. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Note for registration of
transfer, the Company, the Trustee and any agent thereof may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and none of the Company, the Trustee or any such agent
shall be affected by notice to the contrary. 
 All terms used in this Note that are not defined herein and are defined in the Indenture
shall have the meanings assigned to them in the Indenture. 
 To the extent that any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

 WHEREAS,
the Company desires to establish the form and terms of the Notes and to modify, alter, supplement and change certain provisions of the Base Indenture for the benefit of the Holders of the Notes (except as may be provided in a future supplemental

 WHEREAS, the Company has requested that the Trustee execute and

this Supplemental Indenture has been duly authorized in all respects. 
 NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE WITNESSETH: 

For and in consideration of the premises and the purchase of the Notes by the Holders thereof, and for the purpose of setting forth, as
provided in the Indenture, the forms and terms of the Notes, the Company covenants and agrees, with the Trustee, as follows: 

  
 1 

 ARTICLE 1 

DEFINITIONS 

Section 1.1. Definitions. For all purposes of the Indenture, except as otherwise expressly provided or unless the context
otherwise requires: 
 (a) the terms defined in this Article 1 shall have the respective meanings assigned to them in this
Article 1 and include the plural as well as the singular and, to the extent applicable, supersede the definitions thereof in the Base Indenture with respect to the Notes;

“Bankruptcy Law” means Title 11, U.S. Code, as amended, or any similar federal, state or foreign law for the relief of debtors. 

“Below Investment Grade Rating Event” means that at any time within 60 days (which period shall be extended so long as the rating of

Control, the rating on the Notes is lowered, and the Notes are rated below an Investment Grade Rating, by (x) one Rating Agency if the Notes are rated by less than two Rating Agencies, (y) both Rating Agencies if the Notes are rated by two
Rating Agencies or (z) at least a majority of such Rating Agencies if the Notes are rated by three or more Rating Agencies; provided, that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in
rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the
Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or

 In the event of a declaration of acceleration of the Notes solely because an Event of Default
described in Section 6.1(d) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if (i) the default or defaults triggering such Event of Default pursuant to
Section 6.1(d) shall be remedied or cured by the Company or waived by the holders of the relevant indebtedness within 30 days after the declaration of acceleration with respect thereto; (ii) the rescission and annulment of the
acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction; and (iii) all Events of Default with respect to Notes, except non-payment of principal of, or
premium, if any, or interest on, the Notes that have become due solely by such declaration of acceleration of the Notes of such series, have been cured or waived as provided in the Indenture. 

Section 6.2. Acceleration. 

(a) Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of
Securities under the Indenture, whether now or hereafter issued and Outstanding, the first three paragraphs of Section 5.02 of the Base Indenture are hereby replaced with the following with respect to the Notes: 

“If an Event of Default (other than an Event of Default described in Section 6.1(e) of the Supplemental Indenture) occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable by
notice in writing to the Company (and to the Trustee if given by Holders). Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest, if any, will be due and payable immediately. 

If an Event of Default described in Section 6.1(e) occurs and is continuing, the principal of, premium, if any, and accrued and
unpaid interest, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.” 

(b) Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of
Securities under the Indenture, whether now or hereafter issued and Outstanding, the fourth paragraph of Section 5.02 of the Base Indenture is hereby amended by replacing the period at the end of clause (b) thereof with “; and”
and adding the following clause (c) thereafter: “(c) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction.” 

Section 6.3. Control by Holders. Notwithstanding Section 5.12 of the Base Indenture, the Trustee may refuse to follow any
direction that conflicts with any law, rule, regulation or court order or the Indenture or the Notes, or that the Trustee determines in good faith is unduly prejudicial to the rights of any Holder or that would 

  
 12 

 
involve the Trustee in personal liability. Any application by the Trustee for written instructions from the requisite amount of Holders may, at the option of the Trustee, set forth in writing any
action proposed to be taken or omitted by the Trustee under the Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the
Trustee in accordance with a proposal included in such application on or after the date specified in such application unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written
instructions from the requisite amount of Holders in response to such application specifying the action to be taken or omitted. 

Section 6.4. Waivers. It shall not be necessary for any Act of Holders to approve the particular form of any waiver, but it shall
be sufficient if such Act shall approve the substance thereof. A consent to any waiver by any Holder given in connection with a sale, tender or exchange of such Holder’s Notes will not be rendered invalid by such sale, tender or exchange.

DEFEASANCE 

Section 7.1. Covenant Defeasance. The covenants provided pursuant to Section 3.01(r), 9.01(b) or
9.01(g) of the Base Indenture for purposes of Section 13.03 of the Base Indenture are the covenants in Article 5 and Article 8 of this Supplemental Indenture and Section 5.15 of the Base

 ARTICLE 8 

REPURCHASE OF NOTES AT OPTION OF HOLDERS 

Section 8.1. Offer to Repurchase Upon Change of Control Repurchase Event. 

(a) If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem all of the Notes pursuant to
Section 9.1 of this Supplemental Indenture, the Company will make an offer to purchase all the Notes (the “Change of Control Offer”) at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and
unpaid interest, if any, to the date of purchase (the “Change of Control Payment”). If a Note is repurchased pursuant to a Change of Control Offer on or after a Regular Record Date but on or prior to the related Interest Payment Date, then
any accrued and unpaid interest shall be paid to the holder of record as of such Regular Record Date. Within 30 days following the date upon which a Change of Control Repurchase Event occurred, or at the Company’s option, prior to any Change of
Control but after the public announcement of the pending Change of Control, unless the Company has exercised its right to redeem all of the Notes pursuant to Section 9.1 of this Supplemental Indenture, the Company will mail a notice of such
Change of Control Offer to each Holder or otherwise give notice, which will govern the terms of the Change of Control Offer, in accordance with the applicable procedures of DTC, with a copy to the Trustee, stating: 

(i) that a Change of Control Offer is being made pursuant to this Section 8.1 and that all Notes validly tendered pursuant
to such Change of Control Offer will be accepted for purchase by the Company at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase; 

(ii) the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed or
given, other than as may be required by law) (the “Change of Control Payment Date”); 
 (iii) if sent prior to the
date of consummation of the Change of Control, that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date; provided, that if a Change of Control is consummated
after a proposed Change of Control Payment Date and such Change of Control Offer is therefore not consummated, the Company shall make a Change of Control Offer in accordance with this Section 8.1 within 30 days following the later of the
consummation of such Change of Control or a Below Investment Grade Rating Event; 

  
 13 

 (iv) that Notes must be tendered in multiples of $1,000, and any Note not
validly tendered will remain outstanding and continue to accrue interest; 
 (v) that, unless the Company defaults in the
payment of the Change of Control Payment, any Note accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on and after the Change of Control Payment Date; 

(vi) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such
Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice, or transfer their Notes to the Paying Agent by
book-entry transfer pursuant to the applicable procedures of the Paying Agent, prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 

(vii) that Holders shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase
such Notes; provided, that the Paying Agent receives at the address specified in the notice, not later than the close of business on the 30th day following the date of the Change of Control notice, a telegram, facsimile transmission or letter
setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased; 

(viii) that if a Holder is tendering less than all of its Notes, such Holder will be issued new Notes equal in principal amount
to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to $2,000 or an integral multiple of $1,000 in excess thereof); and 

(ix) the other instructions, as determined by the Company, consistent with this Section 8.1 that a Holder must follow.

 The notice, if mailed or given in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder
receives such notice. If (A) the notice is mailed or given in a manner herein provided and (B) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice
or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect. 

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

(i) accept for payment all Notes or portions of Notes (of integral multiples of $1,000) validly tendered pursuant to the Change
of Control Offer; 
 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all
Notes or portions of Notes so tendered; 
 (iii) deliver or cause to be delivered to the Trustee for cancellation the Notes
so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company in accordance with this Section 8.1; and 

(iv) deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent
provided for in the Indenture relating to the making of such Change of Control Payment have been complied with. 
 (c) The Paying Agent will
promptly pay to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate, upon receipt of an authentication order, and mail (or cause to be transferred by book entry) to each Holder a
new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof. 

  
 14 

 (d) If the Change of Control Payment Date is on or after a Regular Record Date and on or
before the related Interest Payment Date, any accrued and unpaid interest to the Change of Control Payment Date will be paid on the relevant Interest Payment Date to the Person in whose name a Note is registered at the close of business on such
Regular Record Date. 
 (e) Prior to making a Change of Control Payment, and as a condition to such payment (i) the requisite holders
of each issue of indebtedness issued under an indenture or other agreement that would be violated by the making of such payment shall have consented to such Change of Control Payment being made and waived the event of default, if any, caused by the
Change of Control or (ii) the Company will repay all outstanding indebtedness issued under an indenture or other agreement that would be violated by the making of a Change of Control Payment or the Company will offer to repay all such
indebtedness, make payment to the holders of such indebtedness that accept such offer and obtain waivers from the requisite remaining holders of such indebtedness of any event of default arising under the relevant indenture or other agreement as a
result of the Change of Control. The Company covenants to effect such repayment or obtain such consent prior to making a Change of Control Payment, it being a default of this Section 8.1 if the Company fails to comply with such covenant. 

(f) The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 8.1 applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such
Change of Control Offer. 
 (g) The Company will comply, to the extent applicable, with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any
securities laws or regulations conflict with provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Indenture by virtue of the
conflict. 
 (h) Other than as specifically provided in this Section 8.1, any purchase pursuant to this Section 8.1 shall be made
pursuant to the provisions of Sections 11.03, 11.05 and 11.07 of the Base Indenture. 
 (i) Notwithstanding anything to the contrary in the
foregoing clauses (a) though (h), the Company’s obligation to make a Change of Control Offer may, subject to Section 4.2(b) of this Supplemental Indenture, be waived or modified with the written consent of the Holders of a
majority in principal amount of the Notes. 
 ARTICLE 9 

OPTIONAL REDEMPTION 

Section 9.1. Optional Redemption. 

(a) At any time prior to July 1, 2028, the Company may redeem the Notes at its option, in whole or in part, upon notice pursuant to
Section 11.04 of the Base Indenture, at a Redemption Price equal to 100% of the aggregate principal amount of the Notes plus the Applicable Premium, plus accrued and unpaid interest, if any, to the Redemption Date. On or after July 1,
2028, the Company may redeem the Notes at its option, in whole or in part, at a Redemption Price equal to 100% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to the Redemption Date. Promptly after the
determination thereof, the Company shall give the Trustee written notice of the Redemption Price provided for in this Section 9.1(a), and the Trustee shall not be responsible for such calculation. If a Note is redeemed on or after a Regular
Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the holder of record as of such Regular Record Date. Unless the Company defaults in payment of the Redemption Price, from and
after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption. 
 (b) Except pursuant to
clause (a) of this Section 9.1, the Notes shall not be redeemable at the Company’s option prior to October 1, 2028. 

  
 15 

 (c) Any redemption pursuant to this Section 9.1 shall be made pursuant to the
provisions of Sections 11.01 through 11.07 of the Base Indenture; provided, that the words “by such method as the Trustee shall deem fair and appropriate and” in Section 11.03 of the Base Indenture shall be replaced with
“by lot.” 
 (d) Any redemption notice may, at the Company’s discretion, be subject to one or more conditions precedent,
including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at the Company’s discretion, the Redemption Date may be delayed until such
time as any or all such conditions shall be satisfied or waived (provided that in no event shall such Redemption Date be delayed to a date later than 60 days after the date on which such notice was given), or such redemption may not occur and such
notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the Redemption Date, or by the Redemption Date as so delayed. 

(e) The Company may acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or
otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture. 

Section 9.2. Modification of Base Indenture. Except as may be provided in a Future Supplemental Indenture, for the benefit of the
Holders of the Notes but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, Section 11.06 of the Base Indenture is hereby amended by deleting the words “Record Dates” and
replacing them with “Regular Record Date.”

 AIR LEASE CORPORATION, a corporation duly organized and existing under the laws of the State of Delaware
(herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., the registered Holder hereof, the principal sum of [ ]
Dollars ($[ ]) (as revised by the Schedule of Increases and Decreases in Global Security attached hereto) on October 1, 2028 and to pay interest thereon from and including September 17, 2018 or from and including the most recent date to which
interest has been paid or duly provided for, semi-annually on April 1 and October 1 in each year, commencing April 1, 2019 (each an “Interest Payment Date”), at the rate of 4.625% per annum (the “Interest Rate”), until the
principal hereof is paid or made available for payment; provided that any principal, and any such installment of interest, that is overdue shall bear interest at the Interest Rate (to the extent that the payment of such interest shall be
legally enforceable), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand. If any Interest Payment Date, Redemption Date or Stated Maturity of a Note is not a Business
Day, the payment otherwise required to be made on such date may be made on the next Business Day with the same force and effect as if made on such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, and no interest shall
accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will,
as provided in such Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the March 15 or September 15
(whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest so payable but not so punctually paid or duly provided for on any Interest Payment Date will forthwith cease to be payable to the
Holder on such Regular Record Date and, at the Company’s election, may either be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment
of such Defaulted Interest to be fixed by the Trustee, notice whereof to be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in such Indenture. 

 Payment of the principal of and interest on this Note will be made at the office or agency
of the Company maintained for that purpose in The City of New York, New York (or, if the Company does not maintain such office or agency, at the corporate trust office of the Trustee in The City of New York or if the Trustee does not maintain an
office in The City of New York, at the office of a Paying Agent in The City of New York), in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided,
however, that payment of principal and interest on Global Securities shall be made by wire transfer in accordance with the procedures of the Depositary. 

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature of one or more authorized signatories, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 [REVERSE OF NOTE] 

This Note is one of a duly authorized series of securities of the Company designated as the “4.625% Senior Notes due 2028” (herein
called the “Notes”), issued under an Indenture, dated as of October 11, 2012 (herein called the “Base Indenture”), as supplemented by the Twentieth Supplemental Indenture dated as of September 17, 2018 (the
“Twentieth Supplemental Indenture”; the Base Indenture, as so supplemented, is herein called the “Indenture”), among the Company, as issuer, and Deutsche Bank Trust Company Americas, as Trustee (herein called the
“Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, initially limited in aggregate principal amount to
$500,000,000. The Company may at any time issue Additional Notes under the Indenture in unlimited amounts having the same terms as the Notes, except as otherwise permitted by the Indenture. 

The Notes do not have the benefit of any sinking fund obligation. 

The Notes are redeemable prior to the Stated Maturity Date as provided in the Indenture. In the event of redemption of this Note in part only,
a new Note or Notes in an authorized denomination for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Note or of certain restrictive covenants and
Events of Default with respect to the Notes, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event
of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 

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

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture or this Note, or for the appointment of a receiver or trustee or for any other remedy thereunder, unless (i) an Event of Default has occurred and is continuing and the Holder of this Note has
previously given written notice to the Trustee of such Event of Default and the continuance thereof, (ii) the Holders of not less than 25% in principal amount of the Outstanding Notes have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee hereunder, (iii) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred in compliance with such request, (iv) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding, and (v) no direction inconsistent with such written
request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of
this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 

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

 As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Note are payable,
duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or the Holder’s attorney duly authorized in writing, and thereupon one or
more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Indenture and this Note are governed by and construed in accordance with the laws of the State of New York. 

The Notes are issuable in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess
thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of any authorized denomination, as requested by the Holder surrendering the same. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Note for registration of
transfer, the Company, the Trustee and any agent thereof may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and none of the Company, the Trustee or any such agent
shall be affected by notice to the contrary. 
 All terms used in this Note that are not defined herein and are defined in the Indenture
shall have the meanings assigned to them in the Indenture. 
 To the extent that any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.
