limited initially to $300,000,000 aggregate Principal Amount (except that the Company may, without the consent of Holders, reopen this series of Notes and issue additional Notes so as to 

  
 4 

 
increase the aggregate Principal Amount of Notes Outstanding in compliance with the procedures set forth in the Base Indenture, so long as any such additional Notes have the same tenor and terms
(including, without limitation, rights to receive accrued and unpaid interest as the Notes then Outstanding); provided that no such additional Notes may be issued unless they are treated as part of the same “issue” as the Notes for U.S.
federal income tax purposes; and further provided that the additional Notes have the same CUSIP number as the Notes). For all purposes of the Indenture, the term “Notes” shall include the Notes initially issued on the date of original
issuance of the Notes and any other Notes issued after such date under the Indenture. For purposes of the Indenture, all Notes shall vote together and otherwise constitute a single series of Securities. 

The Notes shall rank equally and pari passu with all other unsecured and unsubordinated indebtedness of the Company. 

Section 2.02. Forms of Notes. The Notes shall be substantially in the form set forth in Exhibit A hereto with such
appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture, and with such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required
to comply with the rules of any securities exchange or Depositary therefor, the Internal Revenue Code of 1986, as amended, and the regulations thereunder, or as may, consistently herewith, be determined by the officers executing such Notes, as
evidenced by their execution thereof. 
 The terms and provisions contained in the form of Notes attached hereto as Exhibit A
shall constitute, and are hereby expressly made, a part of this Fourth Supplemental Indenture and the Company and the Trustee, by their execution and delivery of this Fourth Supplemental Indenture, expressly agree to such terms and provisions
and to be bound thereby. 
 The Notes shall initially be issued in the form of a permanent Global Note in registered form. The
aggregate Principal Amount of the Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depositary, as hereinafter provided. 

Section 2.03. Denominations. The Notes shall be issuable only in registered form without coupons and in denominations of
$1,000 and integral multiples of $1,000 above that amount. 
 Section 2.04. Registration of Transfer and Exchange.
The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 of the Base Indenture being herein
sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Trustee is
hereby appointed “Security Registrar” (the “Security Registrar”) for the purpose of registering Notes and transfers of Notes as herein provided. 

  
 5 

 Upon surrender for registration of transfer of any Note at an office or agency of the
Company designated pursuant to Section 1002 of the Base Indenture for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any
authorized denominations and of a like aggregate principal amount and tenor. 
 At the option of the Holder and subject to the
other provisions of this Section 2.04 and Section 2.05 hereof and Section 309 of the Base Indenture, Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount and tenor, upon
surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is
entitled to receive. 
 All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations
of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture, as the Notes surrendered upon such registration of transfer or exchange. 
 Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Note Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Notes, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Section 304 of the Base Indenture not involving any transfer. 

If the Company elects to redeem Notes, it shall not be required to (i) issue, register the transfer of or exchange any Note during
the period beginning at the opening of business 15 days before the day the Company mails the notice of redemption and ending at the close of business on the day such notice of redemption is mailed or (ii) register the transfer or exchange of
any Note after a notice of redemption has been given to Holders except, where such notice provides that such Note is to be redeemed only in part, the Company shall be required to exchange or register a transfer of the portion thereof not to be
redeemed. 
 Neither the Trustee nor any of its agents shall (i) have any duty to monitor compliance with or with respect
to any federal or state or other securities or tax laws or (ii) have any duty to obtain documentation relating to any transfers or exchanges other than as specifically required hereunder. 

As used in this Section, the term “transfer” encompasses any sale, pledge, transfer or other disposition of any Note.

 Section 2.05. Book-Entry Provisions for a Global Note. (a) The Global Note initially shall be registered in
the name of the Depositary or the nominee of such Depositary and be delivered to the Trustee as custodian for the Depositary.

 Investors may hold their interests in the Global Note directly through the Depositary,
Euroclear or Clearstream, if they are members of or participants in such systems (“Agent Members”), or indirectly through organizations that are Agent Members in such systems. If interests in the Global Note are held through
Euroclear or Clearstream, Euroclear and Clearstream shall hold such interests in the Global Note through the Depositary on behalf of their Agent Members. 
 Agent Members of the Depositary, Euroclear or Clearstream shall have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian,
or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members,
the operation of customary practices governing the exercise of the rights of any Holder. 
 (b) Transfers of the Global Note
shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may be transferred or exchanged, in whole or in part, for Physical Notes in
accordance with the rules and procedures of the Depositary and the provisions of Section 309 of the Base Indenture. In addition, Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in the
Global Note if (a) such Depositary has notified the Company (or the Company becomes aware) that the Depositary (i) is unwilling or unable to continue as Depositary for such Global Note or (ii) has ceased to be a clearing agency
registered under the Exchange Act when the Depositary is required to be so registered to act as such Depositary and, in either such case, no successor Depositary shall have been appointed within 90 days of such notification or of the Company
becoming aware of such event; (b) there shall have occurred and be continuing an Event of Default with respect to such Global Note; or (c) the Company, at its option, elects to terminate the book-entry system through the Depositary.

 (c) In connection with any transfer or exchange of a portion of the beneficial interest in the Global Note to beneficial
owners pursuant to paragraph (b) above, the Security Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the Principal Amount of the Global Note in an amount equal to the
Principal Amount of the beneficial interest in the Global Note to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of like tenor and amount. 

(d) In connection with the transfer of the entire Global Note to beneficial owners pursuant to paragraph (b) above, the Global Note
shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the
Global Note, an equal aggregate Principal Amount of Physical Notes of authorized denominations and the same tenor. 

  
 7 

 (e) The Holder of the Global Note may grant proxies and otherwise authorize any Person,
including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes. 
 (f) None of the Company, the Trustee, any Paying Agent or any Security Registrar will have any responsibility or liability for any aspect of Depositary records relating to, or payments made on account of,
beneficial ownership interests in a Global Note or for maintaining, supervising or reviewing any Depositary records relating to such beneficial ownership interests, or for transfers of beneficial interests in the Notes or any transactions between
the Depositary and beneficial owners. 
 Section 2.05. Euroclear and Clearstream Procedures Applicable. The
provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions” and “Customer Handbook” of Clearstream shall be
applicable to transfers of beneficial interests in any Global Note held by Agent Members through Euroclear and Clearstream. 

ARTICLE 3 

REDEMPTION 
 Section 3.01. Optional Redemption of Notes by the Company. The Notes will not be redeemable at the option of any Holder thereof, upon the occurrence of any particular event or otherwise. The
Notes will be redeemable, in whole or in part, at the option of the Company, at any time or from time to time, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Notes to be redeemed and (b) the sum of
the present values of the Remaining Scheduled Payments on such Notes discounted to the Redemption Date, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the applicable Treasury Rate
plus 30 basis points (the “Redemption Price”). The Redemption Price will be provided to the Trustee by the Company. 
 The Company shall give notice to the Trustee of its election to redeem Notes by a Company Order, at least 30 days but not more than 60 days before the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee). 
 Section 3.02. Selection of Notes to be Redeemed. If less than all the Notes are to
be redeemed, the Trustee shall select the Notes to be redeemed in accordance with the procedures of the Depositary. The Trustee shall make the selection within 7 days from its receipt of the notice from the Company delivered pursuant to the second
paragraph of Section 3.01 from Outstanding Notes not previously called for redemption. 
 Notes, or portions thereof
selected by the Trustee for redemption, shall be in denominations of $1,000 and integral multiples of $1,000 above that amount. Provisions of the Indenture that apply to Notes called for redemption in whole also apply to Notes called for redemption
in part. The Trustee shall notify the Company promptly of the Notes or portions of Notes to be redeemed. 

  
 8 

 Section 3.03. Notice of Redemption. At least 30 days but not more than 60 days
before a Redemption Date, the Company shall deliver a notice of redemption to each Holder of Notes to be redeemed. The notice shall identify the Notes to be redeemed and shall state: 

(i) the aggregate principal amount of Notes to be redeemed; 

(ii) the Redemption Date; 
 (iii) the amount of interest accrued to the Redemption Date on the Notes to be redeemed; 
 (iv) that on and after the Redemption Date, interest on the Notes to be redeemed, or on the portion thereof to be redeemed, will cease to accrue;

 (viii)
the CUSIP number of the Notes being redeemed. 
 At the Company’s written request delivered at least 30 days prior to the
date such notice is to be given (unless a shorter time period shall be acceptable to the Trustee), the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. 

Section 3.04. Effect of Notice of Redemption. Once notice of redemption is given, Notes called for redemption become due and
payable on the Redemption Date and at the Redemption Price stated in the notice. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price stated in the notice. Unless the Company Defaults on the payment of the Redemption
Price, interest will cease to accrue on the Notes or portions thereof called for redemption. 
 Section 3.05. Deposit of
Redemption Price. Prior to 11:00 a.m. (New York City time) on a Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold
in trust) money sufficient to pay the Redemption Price of all Notes to be redeemed on that date other than Notes or portions of Notes called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation.

 Section 3.06. Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unredeemed portion of the Note surrendered.

 3.80% Senior Notes due 2022 
 Indenture; Defined Terms. This Note is
one of the 3.80% Senior Notes Due 2022 of the Company issued under an Indenture dated February 1, 1987 (the “Base Indenture”), between the Company and J.P. Morgan Trust Company, National Association, as supplemented by the
Fourth Supplemental Indenture dated September 24, 2012 (the “Fourth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) between the Company and The Bank of New York Mellon Trust
Company, N.A. (ultimate successor-in-interest to Morgan Guaranty Trust Company of New York, the “Trustee”). 

Unless otherwise defined herein, capitalized terms herein are used as defined in the Indenture. The terms of the Notes include those
stated in the Indenture and those made part thereof by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “Trust Indenture Act”), as in effect on the date hereof. Notwithstanding anything to the
contrary herein, the Notes are subject to all such terms, and holders of Notes are referred to the Indenture and the Trust Indenture Act for a statement of such terms. To the extent the terms of the Indenture, the Fourth Supplemental Indenture and
this Note are inconsistent, the terms of the Fourth Supplemental Indenture shall govern. 
 Interest. The Company
promises to pay cash interest on the Principal Amount of the Notes at the rate per year described above. Interest on the Notes will accrue from September 24, 2012, or from the most recent Interest Payment Date to which interest has been paid or
duly provided for, to but excluding the next Interest Payment Date. The Company will pay interest semi-annually in arrears on each Interest Payment Date, commencing March 15, 2013, to the Person in whose name the Notes are registered at the
close of business on the immediately preceding Record Date. Interest payable upon redemption will be paid to the Person to whom principal is paid. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

If an Interest Payment Date, the Stated Maturity or a Redemption Date for the Notes falls on a day that is not a Business Day, the
interest payment shall be postponed to the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after such Interest Payment Date, the Stated Maturity or a Redemption Date. 

If a Holder of at least $2,000,000 principal amount of Notes has given wire transfer instructions to the Company no later than 15 days
immediately preceding the relevant due date for payment (or such date as the Trustee may 

  
 A-5

 
accept in its discretion), the Company will pay, or cause to be paid by the Paying Agent, all principal and interest on the Holder’s Notes in accordance with those instructions. Other
payments on the Notes will be made to the Holders at their address set forth in the Security Register. 
 Redemption of Notes
at the Option of the Company. The Notes are redeemable, in whole or in part, at the option of the Company, at any time or from time to time, at a redemption price equal to the greater of (a) 100% of the principal amount to be redeemed and
(b) the sum of the present values of the Remaining Scheduled Payments on such Notes discounted to the Redemption Date, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the
applicable Treasury Rate plus 30 basis points (the “Redemption Price”) upon delivery of the Notes to the Paying Agent by the Holder as set forth in the Indenture. The Redemption Price will be paid in cash. 

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of
the Notes to be redeemed. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be
redeemed, the Notes to be redeemed shall be selected pro rata or by lot or by any other method the Trustee considers fair and appropriate. 
 The Notes are not subject to any sinking fund. 
 Paying Agent. Initially,
The Bank of New York Mellon Trust Company, N.A. will act as Paying Agent. The Company may change any paying agent without notice to the Holders. 
 Covenants. The Indenture contains certain restrictive covenants and provisions for defeasance at any time of (a) the entire indebtedness evidenced by the Notes and (b) such restrictive
covenants, in each case upon compliance by the Company with certain conditions set forth therein, which covenants and provisions apply to the Notes. 
 Events of Default. 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. 
 Amendment; Supplement; Waiver. 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 at any time by the Company and the Trustee with the consent of the Holders of 66 2/3% in aggregate principal amount of Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages

  
 A-6

 
in aggregate principal amount of Notes at the time Outstanding, on behalf of the Holders of the 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 thereof of in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 No reference herein to the Indenture and no provision of the Notes or the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and
interest on the Notes at the times, place and rate, and in the coin or currency, herein prescribed. 
 Persons Deemed
Owners. The registered Holder of this Note may be treated as the owner of this Note for all purposes. 
 Denominations;

Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay to it any taxes and required by law or permitted by the Indenture. The Registrar shall not be required to exchange or register
a transfer of any Note for a period of 15 days immediately preceding a Redemption Date. 
 Authentication. This Note
shall not be valid until the Trustee signs the certificate of authentication on the front hereof. 
 Governing Law. This
Note shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of laws rules of such state.

GENERAL TERMS AND CONDITIONS OF THE DEBENTURES 
 Section 2.01. Designation, Principal Amount and Authorized Denominations. 
 (a) Designation. Pursuant to Sections 2.1 and 2.3 of the Base Indenture, there is hereby established a series of Securities of the Company designated as the 5.875% Junior Subordinated Debentures
due 2052, the principal amount of which to be issued shall be in accordance with Section 2.01(b) hereof and as set forth in any Issuer Order for the authentication and delivery of Debentures pursuant to Section 2.4 of the Base Indenture,
and the form and terms of which shall be as set forth hereinafter. 
 (b) Principal Amount. Debentures in an initial
aggregate principal amount of $125,000,000 shall, upon execution of this Supplemental Indenture, be executed by the Company and delivered to the Trustee or an Authenticating Agent for authentication, and the Trustee or an Authenticating Agent shall
thereupon authenticate and deliver said Debentures in accordance with Section 2.4 of the Base Indenture. Additional Debentures may be issued from time to time pursuant to this Supplemental Indenture on the same terms and conditions as the
Debentures issued under this Supplemental Indenture in all respects, except for any difference in the issue date, issue price and, if applicable, the first payment of interest thereon and the initial interest accrual date. Additional Debentures
issued pursuant to this Supplemental Indenture will be consolidated with, and will form a single series with, the previously outstanding Debentures issued pursuant to this Supplemental Indenture so long as any such additional Debentures have the
same tenor and terms (including, without limitation, rights to receive accrued and unpaid interest as the previously outstanding Debentures); provided that no such additional Debentures may be issued unless they are treated as part of the same
“issue” as the Debentures for U.S. federal income tax purposes; and further provided that the additional Debentures have the same CUSIP number as the Debentures. Any additional Debentures issued under this Supplemental Indenture will rank
equally and ratably in right of payment with the Debentures originally issued under this Supplemental Indenture. 
 (c)
Authorized Denominations. The denominations in which Debentures shall be issuable is a minimum of $25 principal amount and integral multiples of $25 thereafter. 
 Section 2.02. Repayment. 
 The principal of, and all accrued and
unpaid interest on, all Outstanding Debentures shall be due and payable on December 15, 2052 or, if such date is not a Business Day, the following Business Day (the “Maturity Date”). 

  
 5 

 Section 2.03. Form. 

The Debentures shall be substantially in the form of Exhibit A attached hereto and shall be issued in fully registered definitive
form without interest coupons. Principal of and interest on the Debentures issued in definitive form will be payable, the transfer of such Debentures will be registrable and such Debentures will be exchangeable for Debentures bearing identical terms
and provisions and notices and demands to or upon the Company in respect of the Debentures and the Indenture may be served at the Corporate Trust Office of the Trustee, and the Company appoints the Trustee as its agent for the foregoing purposes,
provided that payment of interest may be made at the option of the Company by check mailed to the Holders at such address as shall appear in the Security Register or by wire transfer in immediately available funds to the bank account number
of the Holders specified in writing by the Holders not less than 10 days before the relevant Interest Payment Date and entered in the Security Register by the Security Registrar. The Debentures may be presented for registration of transfer or
exchange at the Security Registrar Office. The Debentures are initially solely issuable as Global Securities. The Depository Trust Company is hereby designated as Depositary. Registered Debentures shall be physically transferred to all beneficial
owners in definitive form in exchange for their beneficial interests in a Global Security if the Depositary with respect to such Global Securities notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security
or the Depositary ceases to be a clearing agency registered under the Exchange Act, as the case may be, and a successor Depositary is not appointed by the Company within 90 days of such notice. 

In addition, beneficial interests in the Global Securities may be exchanged for definitive certificated Debentures upon request by or on
behalf of the Depositary in accordance with customary procedures following the request of a beneficial owner seeking to exercise or enforce its rights under such Debentures in connection with an Event of Default. If the Company determines at any
time that the Debentures shall no longer be represented by a Global Security, the Company shall inform the Depositary of such determination which will, in turn, notify participants of their right to withdraw their beneficial interest from the Global
Security. If such participants then elect to withdraw their beneficial interests, the Company shall issue certificates in definitive form in exchange for such beneficial interests in the Global Security. Any Global Security, or portion thereof, that
is exchangeable pursuant to this Section 2.03 shall be exchangeable for Debenture certificates registered in the names directed by the Depositary. 
 Section 2.04. Interest. 
 (a) From and including the original issue
date up to but excluding the Maturity Date or earlier Redemption Date, as applicable, the Debentures will bear interest, accruing from the date of initial issuance (except as further described in the following sentence), at the per annum rate of
5.875% (the “Coupon Rate”), payable quarterly in arrears on each Interest Payment Date, commencing on December 15, 2012. 
 (b) Interest payments will include accrued interest from and including the last date in respect of which interest has been paid or duly provided for to, but excluding, the next succeeding Interest Payment
Date, the Maturity Date or the Redemption Date, as the case may be. The amount of interest payable for any full Interest Payment Period will be computed on the basis of a 360-day year of twelve thirty-day months, and the amount of interest payable
for any period shorter than a full Interest Payment Period for which interest is computed will be computed on the basis of thirty-day months and, for periods of less than a thirty-day month, the actual number of days elapsed per thirty-day month.

  
 6 

 (c) Otherwise than in connection with the maturity or early redemption of the Debentures or
the payment in whole or in part of deferred or overdue interest on the Debentures, interest on the Debentures may be paid only on an Interest Payment Date. Notwithstanding the preceding sentence, in the event that any Interest Payment Date is not a
Business Day, then payment of interest payable on such Interest Payment Date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of such delay). 

(d) To the extent permitted by applicable law, interest not paid when due hereunder, including, without limitation, all deferred
interest, will accrue and compound quarterly at the Coupon Rate on each Interest Payment Date until paid. References to the term “interest” in this Indenture shall include such Compounded Interest. 

(e) For so long as the Debentures are represented by one or more Global Securities, the interest installment so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the Base Indenture, be paid to the Person in whose name the Debentures (or one or more Predecessor Securities) are registered at the close of business on the Regular Record
Date next preceding the Interest Payment Date, which shall be the record date for such Interest Payment Date; provided that, in the event the Debentures at any time are not represented solely by one or more Global Securities, the Company may select
a different record date for such Interest Payment Date, which shall be at least one Business Day before an Interest Payment Date. Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the
registered Holders of Debentures on such record date, and may be paid to the Person in whose name the Debentures (or one or more Predecessor Securities) is registered at the close of business on a special record date to be fixed by the Trustee for
the payment of such defaulted interest after the Company has deposited with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest, notice whereof shall be given to the registered
Holders of Debentures not less than 10 days prior to such special record date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debentures may be listed, and upon
such notice as may be required by such exchange. 
 Section 2.05. Interest Deferral. 

(a) Option to Defer Interest Payments. 
 (i) So long as no Event of Default with respect to the Debentures has occurred and is continuing, the Company shall have the right on one or more occasions, to defer the payment of interest on the
Debentures for one or more Interest Payment Periods up to five consecutive years, provided that no Deferral Period shall extend beyond the Maturity Date, the earlier accelerated maturity date of the Debentures or other redemption in full of
the Debentures. If the Company shall fail to pay interest on the Debentures on any Interest Payment Date, the Company shall be deemed to elect to defer payment of such interest on such Interest Payment Date, unless the Company shall pay

  
 7 

 
such interest in full within five Business Days after any such Interest Payment Date. If the Company shall have paid all deferred interest on the Debentures, the Company shall have the right to
elect to begin a new Deferral Period pursuant to this Section 2.05. 
 (ii) During a Deferral Period,
interest will continue to accrue on the Debentures at the Coupon Rate, compounded quarterly, as of each Interest Payment Date to the extent permitted by applicable law. 

(iii) The Company shall pay all deferred interest in accordance with the provisions of Section 2.7 of the Base
Indenture applicable to Defaulted Interest. 
 (b) Payment of Deferred Interest. On the Maturity Date or if the principal
amount of the Debentures shall have been accelerated and such acceleration has not been rescinded, the Company shall pay all accrued and unpaid interest, including deferred interest, from any available funds. On any Interest Payment Date the Company
may pay any accrued and unpaid interest from any available funds. 
 (c) Notice of Deferral. The Company shall provide
written notice to the Trustee and the Holders of the Debentures of its election to commence or continue any Deferral Period at least one Business Day and not more than sixty Business Days prior to the applicable Interest Payment Date. Notice of the
Company’s election of a Deferral Period shall be given to the Trustee and each Holder of Debentures at such Holder’s address appearing in the Security Register by first-class mail, postage prepaid. Notwithstanding the foregoing, the
failure of the Company to provide notice in accordance with this Section 2.05(c) of its election to commence or continue any Deferral Period, including any deemed election as provided in Section 2.05(a)(i), shall not affect the validity of
such deferral hereunder. 
 Section 2.06. Events of Default. 

Solely for purposes of the Debentures, the first paragraph of Section 5.1, Section 5.1(a)-(i) and the following three
paragraphs of the Base Indenture shall be deleted and replaced by the following: 
 Section 5.1. EVENTS OF DEFAULT.

 “Event of Default”, wherever used herein with respect to the Debentures, means any one of the following events
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body): 
 (a) default in the payment of interest in full, including Compounded Interest, on any Debenture for a
period of 30 days, other than during a Deferral Period, or on the Maturity Date; 
 (b) default in the payment of principal of
or premium, if any, on any Debenture on the Maturity Date or upon redemption; 

  
 8 

 (c) failure by the Company to comply in any material respect with any of its agreements or
covenants in, or any of the provisions of, the Indenture with respect to the Debentures (other than an agreement, covenant or provision for which non-compliance is elsewhere in this Section specifically dealt with), and such non-compliance continues
for a period of 60 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 principal amount of the Outstanding Debentures, a written notice
specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; 
 (d) a default under any mortgage, agreement, indenture or instrument under which there may be issued, or by which there may be secured, guaranteed or evidenced any Debt of the Company (including this
Indenture) whether such Debt now exists or shall hereafter be created, in an aggregate principal amount then outstanding of $10,000,000 or more, which default (i) shall constitute a failure to pay any portion of the principal of such Debt when
due and payable after the expiration of any applicable grace period with respect thereto or (ii) shall result in such Debt becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, and such
acceleration shall not be rescinded or annulled, or such Debt shall not be paid in full within a period of 30 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 Debentures a written notice specifying such event of default and requiring the Company to cause such acceleration to be rescinded or annulled or to pay in full such Debt and stating that
such notice is a “Notice of Default” hereunder; (it being understood however, that the Trustee shall not be deemed to have knowledge of such default under such agreement or instrument unless either (i) a Responsible Officer of the
Trustee shall have actual knowledge of such default or (ii) a Responsible Officer of the Trustee shall have received written notice thereof from the Company or from any Holder); provided, however, that if such default under such
agreement or instrument is remedied or cured by the Company or waived by the holders of such indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured or waived without
further action upon the part of either the Trustee or any of such Holders; provided, further, that the foregoing shall not apply to any secured Debt under which the obligee has recourse (exclusive of recourse for ancillary matters such as
environmental indemnities, misapplication of funds, costs of enforcement and the like) only to the collateral pledged for repayment so long as the fair market value of such collateral does not exceed 2% of Total Assets at the time of the default;

 (e) the Company, pursuant to or within the meaning of any Bankruptcy Law, (i) commences a voluntary case or proceeding,
(ii) consents to the entry of an order for relief against it in an involuntary case or proceeding, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, (iv) makes a general assignment
for the benefit of its creditors (v) makes an admission in writing of its inability to pay its debts generally as they become due or (vi) takes corporate action in furtherance of any such action; or 

(f) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (i) is for relief against the Company,
in an involuntary case, (ii) adjudges the Company as bankrupt or insolvent, or approves as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company, or appoints a Custodian of the
Company, or for all or substantially all of its property, or (iii) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for 60 days.

 The Trustee shall have no right or obligation under the Indenture or otherwise to exercise
any remedies on behalf of the Holders of the Debentures in connection with any failure by the Company to comply with any covenant or warranty of the Company contained in the Base Indenture (other than any covenant referred to in Section 5.1(a)
or (b)), unless the Trustee is directed to exercise such remedies pursuant to and subject to the provisions of Section 5.9 of the Base Indenture. If an Event of Default has occurred under Section 5.1(e) or Section 5.1(f), the
principal of and accrued but unpaid interest on the Debentures shall automatically, and without any declaration or other action on the part of the Trustee or any Holder of the Debentures, become immediately due and payable. In connection with any
such exercise of remedies, the Trustee shall be entitled to the same immunities and protections and remedial rights (other than acceleration) as if such failure to comply were an Event of Default. The Trustee shall not be charged with knowledge or
notice of any such failure to comply unless and until it shall have received the foregoing direction under Section 5.9 of the Base Indenture.

The Bank of New York Mellon Trust Company, N.A. as Security Registrar and Paying Agent with respect to the Debentures. 

Section 2.08. Subordination.

(i) (A) any indebtedness which by its terms ranks equally with the Debentures in right of payment, including guarantees of such indebtedness, (B) any indebtedness which by its terms is subordinated to the Debentures in right of
payment, which shall rank junior in right of payment to the Debentures, (C) any indebtedness incurred for the purchase of goods or material or for services obtained in the ordinary course of business, which shall rank equally in right of
payment to the Debentures, (D) indebtedness owed by the Company to its subsidiaries, including the Company’s existing 7.100% Junior Subordinated Debentures due 2046, which shall rank equally in right of payment to the Debentures or
(E) indebtedness owed by the Company to its employees, which shall rank equally in right of payment to the Debentures.

conversion or exchange provisions of that capital stock or the security being converted or exchanged; 
 (v)

capital stock under any such plan in the future, or redemptions or repurchases of any rights outstanding under a shareholder rights plan; or

current or deferred interest on Parity Securities and the Debentures made pro rata to the amounts due on such Parity Securities and the Debentures; (ii) any payments of deferred interest on Parity Securities that, if not made, would cause the
Company to breach the terms of the instrument governing such Parity Securities; or (iii) any payment of principal on Parity Securities necessary to avoid a breach of the instrument governing such Parity Securities.

 TORCHMARK CORPORATION 
 5.875% Junior Subordinated Debentures due 2052 
 TORCHMARK
CORPORATION, a corporation organized and existing under the laws of Delaware (hereinafter called the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby
promises to pay to [Cede & Co.]2, or registered assigns, the principal sum of One Hundred Twenty Five Million Dollars ($125,000,000), and all accrued and
unpaid interest thereon on December 15, 2052 or, if such date is not a Business Day, the following Business Day (the “Maturity Date”). 
 The Company further promises to pay interest on said principal sum from September 24, 2012 or from the most recent interest payment date to which interest has been paid or duly provided for. Until
the Maturity Date or earlier Redemption Date, each Debenture will bear interest at the per annum rate of 5.875% (the “Coupon Rate”) payable (subject to the interest deferral provisions of Section 2.05 of the Supplemental
Indenture) quarterly in arrears on March 15, June 15, September 15 and December 15 of each year (each such date, an “Interest Payment Date”), commencing on December 15, 2012, and (to the extent that payment
of such interest is enforceable under applicable law) on any overdue installment of interest at such interest rate, compounded quarterly. Interest payments will include accrued interest from and including the last date in respect of which interest
has been duly paid or provided for to, but not including, the next succeeding Interest Payment Date, the Maturity Date or the Redemption Date, as the case may be. The amount of interest payable for any full Interest Payment Period will be computed
on the basis of a 360-day year of twelve thirty-day months, and the amount of interest payable for any period shorter than a full Interest Payment Period for which interest is computed will be computed on the basis of thirty-day months and, for
periods of less than a thirty-day month, the actual number of days elapsed per thirty-day month. 
 In the event that any date
on which interest is payable on this Debenture is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of such delay).
For so long as the Debentures are represented by one or more Global Securities, the interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Base Indenture, be paid to the
Person in whose name this Debenture (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date next preceding the Interest Payment Date, which shall be the record date for such Interest Payment Date;
provided that in the event the Debentures at any time are not represented solely by one or Global Securities, the Company may select a different record date for such Interest Payment Date, which shall be at least one Business Day before an
Interest Payment Date. Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such record date, and may be paid to the Person in whose

 A-2

 
name the Debentures (or one or more Predecessor Securities) is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest
after the Company has deposited with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest, notice whereof shall be given to the registered Holders of this series of Debenture not less
than ten days prior to such special record date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debentures may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in the Indenture. 
 The principal of (and premium, if any) and the interest
(including Compounded Interest) on this Debenture shall be payable at the office or agency of the Trustee maintained for that purpose in the United States, in any coin or currency of the United States of America which at the time of payment is legal
tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at such address as shall appear in the Security Register; provided
further that, notwithstanding the foregoing provisions of this sentence, for so long as the Depositary (as defined in the Indenture referred to on the reverse hereof) is the Holder of all of the Debentures Outstanding, and provided that
the Depositary has provided wire transfer instructions to the Company or the Paying Agent in a timely manner prior to each Interest Payment Date (which it may do by standing instructions) designating an account of the Depositary or its nominee at a
commercial bank in the United States to which it wishes payments of interest on the Debentures to be made, the Company shall pay interest on the Debentures by wire transfer of federal (same day) funds to the account of the Depositary or its nominee
in accordance with such wire transfer instructions. 
 The indebtedness evidenced by this Debenture is, to the extent provided
in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness, and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Debenture by
accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on its behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and
(c) appoints the Trustee its attorney-in-fact for any and all such purposes. Each Holder hereof, by its acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder
of Senior Indebtedness, whether now Outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions. 
 As provided in the Indenture, so long as no Event of Default has occurred and is continuing, the Company shall have the right on one or more occasions, to defer the payment of interest for one or more
Interest Payment Periods up to five consecutive years, provided that no Deferral Period shall extend beyond the Maturity Date, the earlier accelerated maturity date hereof or other redemption in full hereof. If the Company shall fail to pay interest
hereon on any Interest Payment Date, the Company shall be deemed to elect to defer payment of such interest on such Interest Payment Date, unless the Company shall pay such interest in full within five Business Days after any such Interest Payment
Date. If the Company shall have paid all deferred interest hereon, the Company shall have the right to elect to begin a new Deferral Period as provided in the Indenture. 

  
 A-3

 Reference is hereby made to the further provisions of this Debenture 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, this Debenture shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 Any additional Debentures issued under the same CUSIP as this Debenture shall be fungible with this Debenture for U.S.
federal income tax purposes.

Trustee, the Company and the Holders of the Debentures, and of the terms upon which the Debentures are, and are to be, authenticated and delivered. The terms of the Debentures include those stated in the Indenture, and the Debentures are subject to
all such terms. This Debenture is one of the series designated on the face hereof, initially limited in aggregate principal amount to $125,000,000. 
 All terms used in this Debenture that are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
 This Debenture shall be redeemable at the option of the Company in accordance with the terms of the Indenture. In particular, this Security is redeemable: 

(a) in whole at any time or in part from time to time on or after December 15, 2017; or
