Security, as aforesaid, shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. 
 This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and issuable in one or
more series under a Subordinated Indenture, dated as of             (such Subordinated Indenture as originally executed and delivered and as supplemented or amended from time to time
thereafter, together with any constituent instruments establishing the terms of particular Securities, being herein called the “Indenture”), between the Company and The Bank of New York Mellon, as Trustee (herein called the
“Trustee,” which term includes any successor trustee under the Indenture), to which Indenture, all indentures supplemental thereto and the Officer’s Certificate filed with the Trustee on
            , 20    , creating the series designated on the face hereof (herein called the “Officer’s Certificate”) reference is hereby made for a
description of the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of the Securities thereunder and of the terms and conditions upon which the Securities are, and are to be, authenticated
and delivered. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. This Security is one of the series designated above. 
 If any Interest Payment Date, any Redemption Date, any Optional Repayment Date or the Stated Maturity shall not be a Business Day (as hereinafter
defined), payment of the amounts due on this Security on such date may be made on the next succeeding Business Day, and, if such payment is made or 

  

 2 








 
duly provided for on such next succeeding Business Day, no interest shall accrue on such amounts for the period from and after such Interest Payment Date,
Redemption Date, Optional Repayment Date or Stated Maturity, as the case may be, to such Business Day. 
 [If, as specified above, this
Security is redeemable, this Security is subject to redemption at any time on or after the Initial Redemption Date specified above, in whole or in part in increments of $1,000, at the election of the Company, at the applicable redemption price (as
described below) plus accrued interest to the date fixed for redemption. Such redemption price shall be the Initial Redemption Price specified above for the twelve-month period commencing on the Initial Redemption Date and shall decline for the
twelve-month period commencing on each anniversary of the Initial Redemption Date by a percentage of principal amount equal to the Annual Redemption Percentage Reduction specified above until such redemption price is 100% of the principal amount of
this Security to be redeemed.] 
 [Insert provisions, if any, for redemption pursuant to a sinking fund or other mandatory redemption or
purchase provisions or other put or call provisions.] 
 Notice of redemption (other than at the option of the Holder) shall be given by mail
to Holders of Securities of this series, not less than 30 days nor more than 60 days prior to the date fixed for redemption, all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company as
aforesaid may state that such redemption shall be conditional upon the receipt by the applicable Paying Agent or Agents of money sufficient to pay the principal of and premium, if any, and interest, if any, on this Security on or prior to the date
fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem this Security. 
 In the event of redemption of this Security in part only, a new Security or Securities of this series, of like tenor, representing the unredeemed portion
hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 The indebtedness evidenced by this Security is, to
the extent provided in the Indenture, subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness of the Company, and this Security is issued subject to the provisions of the Indenture with respect thereto.
Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. Each Holder hereof, by his acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions
contained herein and in the Indenture by each holder of Senior Indebtedness of the Company, whether now outstanding or hereafter incurred, and waives reliance by each such Holder upon said provisions. 
 [If this Security is specified on the face hereof to be repayable at the option of the Holder, this Security will be so repaid in whole or in part in
increments of $1,000, provided that the remaining principal amount of any Security surrendered for partial repayment shall be at least $1,000, on any Optional Repayment Date (as stated on the face hereof), at the option of the Holder, at 100% of the
principal amount to be repaid, plus accrued interest, if any, to the repayment date. In order for the exercise of the option to be effective and the Security to be repaid, the Company must receive at the applicable address of the Trustee set forth
below, or at such other place or places of which the Company shall from time to time notify the Holder of this Security, on or before the thirtieth, but not earlier than the sixtieth calendar day, or, if such day is not a Business Day, the next
succeeding Business Day, prior to the repayment date, either (i) this Security, with the form below entitled “Option to Elect Repayment” duly completed, or (ii) a telegram, telex, facsimile transmission, or letter from a member
of a national 

  

 3 








 
securities exchange or the National Association of Securities Dealers, Inc. or a commercial bank or a trust company in the United States of America setting
forth (a) the name, address, and telephone number of the Holder of this Security, (b) the principal amount of this Security and the amount of this Security to be repaid, (c) a statement that the option to elect repayment is being
exercised thereby, and (d) a guarantee stating that the Trustee on behalf of the Company will receive this Security, with the form below entitled “Option to Elect Repayment” duly completed, not later than five Business Days after the
date of such telegram, telex, facsimile transmission, or letter (and this Security and form duly completed are received by the Trustee on behalf of the Company by such fifth Business Day). Any such election shall be irrevocable. The address to which
such deliveries are to be made is The Bank of New York Mellon, Attention: Corporate Trust Administration, 101 Barclay Street, New York, New York 10286 (or, at such other places as the Company shall notify the Holders of the Securities). All
questions as to the validity, eligibility (including time of receipt) and acceptance of any Security for repayment will be determined by the Company, whose determination will be final and binding.] 
 If an Event of Default with respect to the Securities of this series shall occur and be continuing, the principal of this Security 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 Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Indenture with the consent of the Holders of not less than a
majority in aggregate principal amount of the Securities of all series then Outstanding under the Indenture, considered as one class; provided, however, that if there shall be Securities of more than one series Outstanding under the
Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of
the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed
supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities
of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Indenture permits the Trustee to enter into one or more supplemental indentures for limited purposes without the consent
of any Holders of Securities. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities then Outstanding, on behalf of the Holders of all Securities, 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 Security shall be conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and premium, if any, and interest, if any, on this Security at the times, place and rate, in the coin or currency, and in the manner, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein and herein set forth, this Security or any portion of the principal amount hereof
shall be deemed to have been paid for all purposes of the Indenture and to be no longer Outstanding thereunder, and, at the election of the Company, the Company’s entire indebtedness in respect thereof shall be satisfied and discharged, if
there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in 

  

 4 








 
an amount which shall be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without any regard to reinvestment thereof,
shall provide moneys which, together with moneys so deposited, shall be sufficient to pay when due the principal of and premium, if any, and interest, if any, on this Security when due. 
 The Indenture contains terms, provisions and conditions relating to the consolidation or merger of the Company with or into, and the conveyance or other
transfer, or lease, of assets to, another Person, to the assumption by such other Person, in certain circumstances, of all of the obligations of the Company under the Indenture and on the Securities and to the release and discharge of the Company in
certain circumstances, from such obligations. 
 As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office of The Bank of New York Mellon in New York, New York or such other office or agency as may be designated by
the Company from time to time, 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 his attorney duly authorized in writing, and
thereupon one or more new Securities of this series of authorized denominations and of like tenor and aggregate principal amount, shall be issued to the designated transferee or transferees. 
 The Securities of this series are issuable only as registered Securities, without coupons, and in denominations of $1,000 and integral multiples thereof.
As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of the same series and Tranche, of any authorized denominations, as
requested by the Holder surrendering the same, and of like tenor upon surrender of the Security or Securities to be exchanged at the office of The Bank of New York Mellon in New York, New York or such other office or agency as may be designated by
the Company from time to time. 
 The Company shall not be required to execute and the Security Registrar shall not be required to register
the transfer of or exchange of (a) Securities of this series during a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities of this series called for redemption or (b) any
Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 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 Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the absolute owner hereof for all purposes (subject to Sections 305 and 307 of the Indenture), whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent
shall be affected by notice to the contrary. 
 The Indenture and the Securities shall be governed by and construed in accordance with the
laws of the State of New York (including, without limitation, Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act shall be applicable. 
 As used herein, “Business Day” means any day, other than a Saturday or Sunday, that is not a day on which banking institutions or trust
companies are generally authorized or required by law, regulation 

  

 5 








 
or executive order to close in The City of New York or other city in which is located any Paying Agent for the Securities of this series. All other terms
used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
 As provided in the
Indenture, no recourse shall be had for the payment of the principal of or premium, if any, or interest on any Securities or any part thereof, or for any claim based thereon or otherwise in respect thereof, or of the indebtedness represented
thereby, or upon any obligation, covenant or agreement under the Indenture, against, and no personal liability whatsoever shall attach to, or be incurred by, any member, officer, director or manager, as such, past, present or future of the Company
or of any predecessor or successor of the Company (either directly or through the Company or a predecessor or successor of the Company), whether by virtue of any constitutional provision, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly agreed and understood that the Indenture and this Security are solely obligations of the Company and that any such personal liability is hereby expressly waived and released as a condition of,
and as part of the consideration for, the execution of the Indenture and the issuance of this Security. 
 Unless the certificate of
authentication hereon has been executed by the Trustee or an Authenticating Agent by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.
