WHEREAS, all conditions necessary to authorize the execution and delivery of this Fifth Supplemental Indenture and to make it a valid and binding obligation of the Company have been done or performed.

NOW, THEREFORE, in consideration of the agreements and obligations set forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

Section 1.01 Establishment. There is hereby established a new series of Debt Securities to be issued under the Indenture, to be designated as the Company’s 6-3/8% Senior Notes due June 12, 2042 (the “Senior Notes”).

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount of $200,000,000 (or up to $230,000,000 if the underwriters exercise in full their option to purchase additional Senior Notes pursuant to the Purchase Agreement by and among the Company and Banc of America Securities LLC, UBS Investment Bank and Wells Fargo Securities, LLC dated June 7, 2012), and no further Senior Notes shall be authenticated and delivered except as provided by Section 2.1,

3.5, 3.6, 9.6 and 11.7 of the Indenture; provided further, that the aggregate principal amount of the Senior Notes may be increased in the future, without the consent of the Holders of the Senior Notes, on the same terms and with the same CUSIP number as the Senior Notes, provided that such further Senior Notes are fungible for U.S. federal income tax purposes with such previously issued Senior Notes. The Senior Notes shall be issued in definitive fully registered form.

The Senior Notes shall be issued in the form of one Global Security in substantially the form set out in Exhibit A hereto. The U.S. Depositary with respect to the Senior Notes shall be The Depository Trust Company.

The form of the Trustee’s Certificate of Authentication for the Senior Notes shall be in substantially the form set forth in Exhibit B hereto.

Each Senior Note shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for.

Section 1.02 Definitions. (a) The following defined terms used herein shall, unless the context otherwise requires, have the meanings specified below. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

“Interest Payment Date” means March 12, June 12, September 12 and December 12 of each year.

“Regular Record Date” means February 27, May 27, August 27 and November 27; as the case may be, next preceding the relevant Interest Payment Date.

Section 1.03 Payment of Principal and Interest. The entire outstanding principal amount of the Senior Notes shall be due and payable, unless accelerated, redeemed or required to be repurchased pursuant to the Indenture, at Final Maturity. The unpaid principal amount of the Senior Notes shall bear interest at the rate of 6-3/8% per annum until paid or duly provided for. Interest shall be paid quarterly in arrears on each Interest Payment Date, commencing September 12, 2012, to the Person in whose name the Senior Notes are registered on the Regular Record Date for such Interest Payment Date, provided that interest payable at Final Maturity will be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the Holders on such Regular Record Date and may be paid as provided in Section 3.7 of the Indenture.

Payments of interest on the Senior Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Senior Notes shall be computed and paid on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Senior Notes is not a Business Day, then a payment of the interest payable on such date will be made on the next succeeding day that is a Business Day, except that, notwithstanding Section 1.13 of the Indenture, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the date the payment was originally payable. No interest will accrue due to any delay in payment on the amount so payable for the period from such Interest Payment Date to the date payment is made.

Payment of the principal and interest due at Final Maturity of the Senior Notes shall be made at the office or agency of the Company maintained for that purpose in the Place of Payment, 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, at the option of the Company, interest may be paid by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; provided, further, that payment to the U.S. Depositary or any successor depositary may be made by wire transfer to the account designated by the U.S. Depositary or such successor depositary in writing.

Section 1.04 Denominations. The Senior Notes may be issued in denominations of $25.00, or any integral multiple of $25.00 in excess thereof.

Section 1.05 Global Securities. The Senior Notes will be issued in the form of one or more Global Securities registered in the name of the U.S. Depositary or its nominee. Except under the limited circumstances described below, Senior Notes represented by the Global Security will not be exchangeable for, and will not otherwise be issuable as, Senior Notes in definitive form. The Global Securities described above may not be transferred except as a whole by the U.S. Depositary to a nominee of such U.S. Depositary or by a nominee of such U.S. Depositary to such depositary or another nominee of such U.S. Depositary or by such U.S. Depositary or any other such nominee to a successor U.S. Depositary or a nominee of such successor U.S. Depositary.

Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and no Global Security representing a Senior Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the U.S. Depositary or its nominee or to a successor U.S. Depositary or its nominee. The rights of Holders of such Global Security shall be exercised only through the U.S. Depositary.

A Global Security shall be exchangeable for Senior Notes registered in the names of Persons other than the U.S. Depositary or its nominee only as provided by Section 3.5 of the Indenture. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Senior Notes registered in such names as the U.S. Depositary shall direct.

Section 1.06 Redemption at the Option of the Company. The Senior Notes may not be redeemed prior to June 12, 2017. On or after June 12, 2017, the Company, at its option, may redeem the Senior Notes, in whole at any time or in part from time to time, at 100% of their principal amount, plus accrued interest to, but excluding, the date of redemption.

Section 1.07 Governing Law. Section 1.12 of the Indenture is hereby amended and restated to read in its entirety as follows:

THIS INDENTURE AND THE DEBT SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICTS OF LAW RULES OF SUCH STATE. THIS INDENTURE IS SUBJECT TO THE PROVISIONS OF THE TRUST INDENTURE ACT OF 1939, AS AMENDED, THAT ARE REQUIRED TO BE PART OF THIS INDENTURE AND SHALL, TO THE EXTENT APPLICABLE, BE GOVERNED BY SUCH PROVISIONS.”

Section 1.08 Registration, Registration of Transfer and Exchange. Section 3.5 of the Indenture is hereby amended and restated to read in its entirety as follows:

“SECTION 3.5 Registration, Registration of Transfer and Exchange. The Company shall keep or cause to be kept for the Debt Securities of each series a register (the register maintained in such office being herein sometimes referred to as the “Debt Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration, registration of transfer and exchange of Debt Securities. The Trustee is hereby initially appointed “Debt Security Registrar” for such purposes.

Upon surrender for registration of transfer of any Debt Security of any particular series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee for the Debt Securities of each series shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Debt Securities of any authorized denominations, and of a like Stated Maturity and of a like series and aggregate principal amount and with like terms and conditions.

Except as set forth below, at the option of the Holder, Debt Securities of any particular series may be exchanged for other Debt Securities of any authorized denominations, and of a like Stated Maturity and of a like series and aggregate principal amount and with like terms and conditions, upon surrender of the Debt Securities to be exchanged at such office or agency. Whenever any Debt Securities are so surrendered for exchange, the Company shall execute, and the Trustee for such Debt Securities shall authenticate and deliver, the Debt Securities which the Holder making the exchange is entitled to receive.

All Debt Securities issued upon any registration of transfer or exchange of Debt Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Debt Securities surrendered upon such registration of transfer or exchange.

Every Debt Security presented or surrendered for registration of transfer or exchange shall (if so required by the Company or the Trustee for such Debt Security) be duly endorsed, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Debt Security Registrar for such series 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 Debt Securities, 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 Debt Securities, other than exchanges pursuant to Section 3.4, 9.6, 11.3 or 11.7 not involving any transfer.

Notwithstanding any other provision of this Section, unless and until it is exchanged in whole or in part for Debt Securities in definitive form, a Global Security representing all or a portion of the Debt Securities of a series may not be transferred except as a whole by the U.S. Depositary for such series to a nominee of such U.S. Depositary or by a nominee of such U.S. Depositary to such depositary or another nominee of such U.S. Depositary or by such U.S. Depositary or any other such nominee to a successor U.S. Depositary for such series or a nominee of such successor U.S. Depositary.

If at any time the U.S. Depositary for the Debt Securities of a series notifies the Company that it is unwilling or unable to continue as U.S. Depositary for the Debt Securities of such series or if at any time the U.S. Depositary for Debt Securities of such series shall no longer be a clearing agency registered and in good standing under the Exchange Act or other applicable statute or regulation, the Company shall appoint a successor U.S. Depositary for the Debt Securities of such series. If a successor U.S. Depositary for the Debt Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series, will authenticate and deliver, Debt Securities of such series in definitive form in an aggregate principal

amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

The Company may at any time and in its sole discretion determine that the Debt Securities of any series issued in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series, will authenticate and deliver, Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

If the Debt Securities of any series shall have been issued in the form of one or more Global Securities and if an Event of Default with respect to the Debt Securities of such series shall have occurred and be continuing, the Company will promptly execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series, will authenticate and deliver Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

The U.S. Depositary for such series of Debt Securities may surrender a Global Security for such series of Debt Securities in exchange in whole or in part for Debt Securities of such series of like tenor and terms and in definitive form on such terms as are acceptable to the Company and such U.S. Depositary. Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without charge:

(1) to each Person specified by the U.S. Depositary a new Debt Security or Securities of the same series, of like tenor and terms and of any authorized denomination as requested by such Person in an aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and

(2) to the U.S. Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of the Debt Securities delivered to Holders thereof.

Upon the exchange of a Global Security for Debt Securities in definitive form, such Global Security shall be canceled by the Trustee. Definitive Debt Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the U.S. Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such definitive Debt Securities to the Persons in whose names such Debt Securities are so registered.”

Section 1.09 Title; Payment and Terms. The last paragraph of Section 3.1 of the Indenture is hereby amended and restated to read in its entirety as follows:

“All Debt Securities of any particular series shall be substantially identical except as to denomination, rate of interest, Stated Maturity and the date from which interest, if any, shall accrue, and except as may otherwise be provided in or pursuant to such Board Resolution relating thereto. The terms of such Debt Securities, as set forth above, may be determined by the Company from time to time if so provided in or established pursuant to the authority granted in a Board Resolution. Any of the terms of

the Debt Securities, as set forth above, may be made dependent upon facts ascertainable outside the Board Resolution provided that the manner in which said facts shall operate upon the terms is set forth in the Board Resolution. All Debt Securities of any one series need not be issued at the same time, and unless otherwise provided, a series may be reopened, without notice to or the consent of the registered holders of such Debt Securities, for issuances of additional Debt Securities of such series. Such additional Debt Securities will rank pari passu with the outstanding Debt Securities of such series in all material respects, or in all respects except for the issue date and public offering price or payment of interest accruing prior to the issue date of such additional Debt Securities or except for the first payment of interest following the issue date of such additional Debt Securities, and so that such additional Debt Securities may be consolidated and form a single series with the outstanding Debt Securities of such series and have the same terms as to status, redemption or otherwise as the outstanding Debt Securities of such series; provided that such additional Debt Securities are fungible for U.S. federal income tax purposes with such previously issued Debt Securities”

Section 1.10 Mutilated, Destroyed, Lost and Stolen Debt Securities. Section 3.6 of the Indenture is hereby amended and restated to read in its entirety as follows:

“SECTION 3.6 Mutilated, Destroyed, Lost and Stolen Debt Securities. If (i) any mutilated Debt Security is surrendered to the Trustee for such Debt Security, or the Company and the Trustee for a Debt Security receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security, and (ii) there is delivered to the Company, the Debt Security Registrar and such Trustee such security or indemnity as may be reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or such Trustee that such Debt Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request such Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Debt Security or in exchange for such mutilated Debt Security, a new Debt Security of the same series and in a like principal amount and of a like Stated Maturity and with like terms and conditions and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Debt Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Debt Security, pay such Debt Security (without surrender thereof except in the case of a mutilated Debt Security) if the applicant for such payment shall furnish to the Company, the Debt Security Registrar and the Trustee for such Debt Security such security or indemnity as may be reasonably required by them to save each of them harmless, and in case of destruction, loss or theft, evidence reasonably satisfactory to the Company and such Trustee and any agent of either of them of the destruction, loss or theft of such Debt Security and the ownership thereof.

Upon the issuance of any new Debt Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including all fees and expenses of the Trustee and the Debt Security Registrar for such Debt Security) connected therewith.

Every new Debt Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Debt Security or in exchange for any mutilated Debt Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debt Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debt Securities of the same series, duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) the assertion of any Holder of all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities.”

Section 1.11 Events of Default. Section 5.1 of the Indenture is hereby amended and restated to read in its entirety as follows:

“SECTION 5.1 Events of Default. “Event of Default” wherever used herein with respect to any particular series of Debt Securities, unless otherwise specified in the Debt Security or the Board Resolution with respect to that series of Debt Securities, 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 pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) default in the payment of any installment of interest upon any Debt Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or

(2) default in the payment of the principal of (or premium, if any, on) any Debt Security of that series at its Maturity; or

(3) default in the performance of, or breach of, any covenant or warranty of the Company in respect of any Debt Security of that series contained in this Indenture or in such Debt Securities (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which expressly has been included in this Indenture solely for the benefit of Debt Securities of a series other than that series) or in the applicable Board Resolution under which such series is issued as contemplated by Section 3.1 and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee for the Debt Securities of such series or to the Company and such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series 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; or

(4) if an event of default with respect to any other series of Debt Securities or as defined in any mortgage, indenture, security agreement or other instrument under which there may be issued, or by which there may be secured or evidenced, any Indebtedness of the Company for money borrowed in excess of $10 million principal amount, whether such Indebtedness now exists or shall hereafter be created, shall happen and, if such Indebtedness is not already matured in accordance with its terms, shall result in such Indebtedness 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 have been rescinded or annulled or such Indebtedness shall not have been discharged, in either case, within a period of ten days after there has been given, by registered or certified mail in the manner set forth in Section 1.5, to the Company by the Trustee for the Debt Securities of that particular series referred to in the first clause of this Section 5.1 or to the Company and such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that particular series referred to in the first clause of this Section 5.1 a written notice specifying such event of default and requiring the Company to cause such acceleration to be rescinded or annulled or to cause such Indebtedness to be discharged and stating that such notice is a “Notice of Default” hereunder; provided, that if prior to the entry of judgment in favor of the Trustee, such default under such indenture or instrument shall be remedied or cured by the Company or waived by the holders of such Indebtedness, then the Event of Default hereunder shall be deemed likewise to have been remedied, cured or waived; and provided, further, however, that, subject to the provisions of Sections 6.1 and 6.2, such Trustee shall not be deemed to have knowledge of such default unless either

(A) a Responsible Officer of such Trustee assigned to its Corporate Trust Office shall have actual knowledge of such default or (B) the Trustee shall have received written notice thereof from the Company, from the Holders of 10% or more in principal amount of the Outstanding Debt Securities of such other series, from the holder of any such Indebtedness or from the trustee under any such mortgage, indenture, security agreement or other instrument; or

(5) the entry against the Company of one or more judgments, decrees or orders by a court having jurisdiction in the premises from which no appeal may be or is taken for the payment of money, either individually or in the aggregate, in excess of $10 million and the continuance of such judgment, decree or order unsatisfied and in effect for any period of 60 consecutive days without a stay of execution and there has been given, by registered or certified mail in the manner set forth in Section 1.5, to the Company by the Trustee for the Debt Securities of such series or to the Company and such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of such series a written notice specifying such entry and continuance of such judgment, decree or order and stating that such notice is a “Notice of Default” hereunder; provided, however, that subject to the provisions of Sections 6.1 and 6.2, such Trustee shall not be deemed to have knowledge of such entry and continuance of such judgment, decree or order unless either (A) a Responsible Officer of such Trustee assigned to its Corporate Trust Office shall have actual knowledge thereof or (B) the Trustee shall have received written notice thereof from the Company or from the Holders of 10% or more in principal amount of the Outstanding Debt Securities of such series; or

(6) the Company shall commence any case or proceeding seeking to have an order for relief entered on its behalf as debtor or to adjudicate it as bankrupt or insolvent or seeking reorganization, liquidation, dissolution, winding-up, arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization, liquidation, dissolution, arrangement, composition, readjustment of debt or other similar act or law of any jurisdiction, domestic or foreign, now or hereafter existing; or the Company shall apply for a receiver, custodian or trustee (other than any trustee appointed as a mortgagee or secured party in connection with the issuance of indebtedness for borrowed money of the Company) of it or for all or a substantial part of its property; or the Company shall make a general assignment for the benefit of creditors; or the Company shall take any corporate action in furtherance of any of the foregoing; or

(7) any case or proceeding against the Company shall be commenced seeking to have an order for relief entered against it or to adjudicate it as bankrupt or insolvent or seeking reorganization, liquidation, dissolution, winding-up, arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization, liquidation, dissolution, arrangement, composition, readjustment of debt or other similar act or law of any jurisdiction, domestic or foreign, now or hereafter existing; or a receiver, custodian or trustee (other than any trustee appointed as a mortgagee or secured party in connection with the issuance of indebtedness for borrowed money of the Company) of the Company or for all or a substantial part of its property shall be appointed in any such case or proceeding; and such case or proceeding (A) results in the entry of an order for relief or a similar order against it or (B) shall continue unstayed and in effect for a period of 60 consecutive days.”

Section 1.12 Acceleration of Maturity; Rescission and Annulment. Section 5.2 of the Indenture is hereby amended and restated to read in its entirety as follows:

“SECTION 5.2 Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 5.1(6) or (7)) with respect to any particular series of Debt Securities occurs and is continuing, then and in every such case either the Trustee for the Debt Securities of such series or the Holders of not less than 25% in principal amount of the Outstanding Debt Securities of that series may declare the entire principal amount (or, in the case of Discounted Debt

Securities, such lesser amount as may be provided for in the terms of that series) of all the Debt Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to such Trustee if given by Holders), and upon any such declaration of acceleration such principal or such lesser amount, as the case may be, together with accrued interest and all other amounts owing hereunder, shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived.

If an Event of Default specified in Sections 5.1(6) or (7) occurs and is continuing, such principal or such lesser amount, as the case may be, together with accrued interest and all other amounts owing hereunder, on the Debt Securities of that series shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee for the Debt Securities of any series as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Debt Securities of that series, by written notice to the Company and such Trustee, may rescind and annul such declaration and its consequences if:

(B) the principal of (and premium, if any, on) any Debt Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon from the date such principal became due at a rate per annum equal to the rate borne by the Debt Securities of such series (or, in the case of Discounted Debt Securities, the Debt Securities’ Yield to Maturity), to the extent that the payment of such interest shall be legally enforceable;

(C) to the extent that payment of such interest is lawful, interest upon overdue interest at a rate per annum equal to the rate borne by the Debt Securities of such series (or, in the case of Discounted Debt Securities, the Debt Securities’ Yield to Maturity);

(D) all sums paid or advanced by such Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of such Trustee, its agents and counsel and all other amounts due to such Trustee under; and

(2) all Events of Default with respect to the Debt Securities of such series, other than the nonpayment of the principal of Debt Securities of that series which has become due solely by such acceleration, have been cured or waived as provided in Section 5.13. No such rescission shall affect any subsequent default or impair any right consequent thereon.”

Section 1.13 Acceptance of Appointment by Successor. Paragraph (a) of Section 6.11 of the Indenture is hereby amended and restated to read in its entirety as follows:

(a) Every such successor Trustee appointed hereunder with respect to the Debt Securities of any series shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of

the Company or the successor Trustee, such retiring Trustee shall, upon payment of its reasonable charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject to the lien provided for in Section 6.7.”

Section 1.14 Supplemental Indentures With Consent of Holders. Section 9.2 of the Indenture is hereby amended and restated to read in its entirety as follows:

“SECTION 9.2 Supplemental Indentures With Consent of Holders. The Company, when authorized by a Board Resolution, and the Trustee for the Debt Securities of any or all series may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of such Debt Securities under this Indenture, but only with the consent of the Holders of more than 50% in aggregate principal amount of the Outstanding Debt Securities of each series of Debt Securities then Outstanding affected thereby, in each case by Act of said Holders of Debt Securities of each such series delivered to the Company and the Trustee for Debt Securities of each such series; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Debt Security affected thereby:

(1) change the Stated Maturity of the principal of, or any installment of principal of or interest or premium, if any, on, any Debt Security, or reduce the principal amount thereof or the rate of interest thereon, if any, or any premium or other amounts payable upon the redemption thereof, or reduce the amount of the principal of a Discounted Debt Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 5.2, or change the Place of Payment, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date); or

(2) reduce the percentage in principal amount of the Outstanding Debt Securities of any particular series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture; or

(3) modify any of the provisions of this Section or Section 5.13 or 10.7, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Debt Security affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder of a Debt Security with respect to changes in the references to “the Trustee” and concomitant changes in this Section and Section 10.7, or the deletion of this proviso, in accordance with the requirements of Section 6.9, 6.11(b) and 9.1(6); or

(6) make the principal of, or premium, if any, or interest on, any Debt Security payable in anything other than United States Dollars.

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Debt Securities, or which modifies the rights of the Holders of Debt Securities of such series with respect

to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Debt Securities of any other series.

It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. “

UNLESS THIS SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE COMPANY (AS DEFINED BELOW) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY SECURITY ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC) ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

American Financial Group, Inc., an Ohio corporation (hereinafter called the “Company”, which term includes any successor corporation under the Indenture referred to below), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal amount of each Senior Note evidenced hereby (Two Hundred Million Dollars ($200,000,000) in the aggregate) on June 12, 2042, and to pay interest thereon from June 12, 2012 or from the most recent date to which interest has been paid or duly provided for, quarterly on March 12, June 12, September 12 and December 12 in each year (each, an “Interest Payment Date”), commencing September 12, 2012, at the rate of 6-3/8% per annum, until the principal amount of each Senior Note evidenced hereby is paid or duly made available for payment. Interest on the Senior Notes shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. 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 certificate is registered at the close of business on the Regular Record Date for such interest, which shall be the February 27, May 27, August 27 and November 27 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the registered Holder hereof on the relevant Regular Record Date by virtue of having been such Holder, and may be paid to the Person in

whose name this certificate 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 shall be given to each Person in whose name a certificate evidencing Senior Notes (defined below) is registered 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 Senior 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 the interest on the Senior Notes evidenced hereby will be made at the office or agency of the Company maintained for that purpose in the Place of Payment, 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, at the option of the Company, interest may be paid by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; provided, further, that payment to The Depository Trust Company (“DTC”) or any successor depositary may be made by wire transfer to the account designated by DTC or such successor depositary in writing.

This certificate evidences part of a duly authorized issue of unsecured and unsubordinated indebtedness of the Company (the “Debt Securities”) issued and to be issued in one or more series under an Indenture dated as of November 12, 1997 (herein called, together with all indentures supplemental thereto, the “Indenture”) between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Debt Securities, and of the terms upon which the Debt Securities are, and are to be, authenticated and delivered. This certificate evidences Debt Securities of the series designated on the face hereof (each, a “Senior Note”), limited to $200,000,000; provided, that the aggregate principal amount of the Senior Notes may be increased in the future, without the consent of the Holders of the Senior Notes, on the same terms and with the same CUSIP number as the Senior Notes, provided that such further Senior Notes are fungible for U.S. federal income tax purposes with such previously issued Senior Notes.

The Senior Notes may not be redeemed prior to June 12, 2017. On or after June 12, 2017, the Company, at its option, may redeem the Senior Notes, in whole at any time or in part from time to time, at 100% of their principal amount, plus accrued interest to, but excluding, the date of redemption.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Person in whose name a certificate evidencing Senior Notes to be redeemed is registered at its registered address. Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on such Senior Notes called for redemption.

Except as provided above, the Senior Notes are not redeemable by the Company prior to maturity and are not subject to any sinking fund. If an Event of Default with respect to the Senior Notes shall occur and be continuing, the principal amount of the Senior Notes shall be immediately, or may be declared, as appropriate, 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 Securities of each series issued under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, 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 certificate shall be conclusive and binding upon such Holder and upon all future Holders of this certificate and of any Senior Notes evidenced by a certificate 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 certificate.

No reference herein to the Indenture and no provision of this certificate or of 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 Senior Notes evidenced by this certificate, at the times, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

As provided in the Indenture and subject to certain limitations set forth therein and in this certificate, the transfer of the Senior Notes evidenced by this certificate may be registered on the Security Register upon surrender of this certificate for registration of transfer at the office or agency of the Company maintained for the purpose in any place where the principal of and interest on the Senior Notes are payable, duly endorsed by, or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new certificates evidencing Senior Notes of authorized denominations, and of a like series and aggregate principal amount, and with like terms and conditions will be issued to the designated transferee or transferees.

The Senior Notes are issuable only in registered form without coupons in denominations of $25.00, or any integral multiple of $25.00 in excess thereof, all as more fully provided in the Indenture. As provided in the Indenture, and subject to certain limitations set forth in the Indenture, and in this certificate, this certificate is exchangeable for a like aggregate principal amount of Senior Notes of this series in different authorized denominations, as requested by the Holders 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, other than in certain cases provided in the Indenture.

Prior to due presentment of this certificate 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 certificate is registered as the owner of the Senior Notes evidenced hereby for all the purpose of receiving payment of principal of and (subject to Section 3.7 of the Indenture) interest, if any, on these Senior Note and for all purposes whatsoever, whether or not such Senior Notes be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This certificate 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.

All terms used in this certificate which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Unless the certificate of authentication hereon has been executed by or on behalf of the Trustee under the Indenture by the manual signature of one of its authorized signatories, this certificate shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its corporate seal.
