D.The Corporation acknowledges that reliance by each Covered Debtholder upon the covenants in this Replacement Capital Covenant is reasonable and foreseeable by the Corporation and that, were the Corporation to disregard its covenants in this Replacement Capital Covenant, each Covered Debtholder would have sustained an injury as a result of its reliance on such covenants.

(i) the Corporation shall identify each series of its then outstanding unsecured, long-term indebtedness for money borrowed that is Eligible Debt;

(ii) if only one series of the Corporation’s then outstanding unsecured, long-term indebtedness for money borrowed is Eligible Debt, such series shall become the Covered Debt commencing on the related Redesignation Date;

(iii) if the Corporation has more than one outstanding series of unsecured, long-term indebtedness for money borrowed that is Eligible Debt, then the Corporation shall identify the series that has the latest stated final maturity date as of the date the Corporation is applying the procedures in this Section 3(b) and such series shall become the Covered Debt on the related Redesignation Date;

(iv) the series of outstanding long-term indebtedness for money borrowed that is determined to be Covered Debt pursuant to clause (ii) or (iii) above shall be the Covered Debt for purposes of this Replacement Capital Covenant for the period commencing on the related Redesignation Date and continuing to but not including the Redesignation Date as of which a new series of outstanding unsecured, long-term indebtedness is next determined to be the Covered Debt pursuant to the procedures set forth in this Section 3(b); and

SECTION 4.Termination, Amendment and Waiver. (a) The obligations of the Corporation pursuant to this Replacement Capital Covenant shall remain in full force and effect until the earliest date (the “Termination Date”) to occur of (i) March 29, 2047, or, if earlier, the date on which the Debentures are otherwise repaid, redeemed, defeased, satisfied and discharged or purchased in full (in compliance with the terms of this Replacement Capital Covenant), (ii) the date, if any, on which the Holders of at least a majority of the then outstanding principal amount of the then-effective series of Covered Debt consent or agree in writing to the termination of this Replacement Capital Covenant and the obligations of the Corporation hereunder and (iii) the date on which the Corporation ceases to have any series of outstanding Eligible Senior Debt or Eligible Subordinated Debt (in each case without giving effect to the rating requirement in clause (b) of the definition of each such term). Moreover, if an event of default under the Supplemental Indenture resulting in an acceleration of the Debentures occurs, this Replacement Capital Covenant shall, without any further action, immediately terminate upon such acceleration. From and after the Termination Date, the obligations of the Corporation pursuant to this Replacement Capital Covenant shall be of no further force and effect.

(b) This Replacement Capital Covenant may be amended or supplemented from time to time by a written instrument signed by the Corporation with the consent of the Holders of at least a majority of the then outstanding principal amount of the then-effective series of Covered Debt,provided that this Replacement Capital Covenant may be amended or supplemented from time to time by a written instrument signed only by the Corporation (and without the consent of the Holders of the then-effective series of Covered Debt) if any of the following apply (it being understood that any such amendment or supplement may fall into one or more of the following): (i) the effect of such amendment or supplement is solely to impose additional restrictions on, or to eliminate certain of, the types of securities qualifying as Replacement Capital Securities and an officer of the Corporation has delivered to the Holders of the then-effective series of Covered Debt in the manner provided for in the indenture, fiscal agency agreement or other instrument with respect to such Covered Debt a written certificate to that effect, (ii) such amendment or supplement is not adverse to the rights of the Covered Debtholders hereunder and an officer of the Corporation has delivered to the Holders of the then-effective series of Covered Debt in the manner provided for in the indenture, fiscal agency agreement or other instrument with respect to such Covered Debt a written certificate stating that, in his or her determination, such amendment or supplement is not adverse to the Covered Debtholders, or (iii) such amendment or supplement eliminates Common Stock and/or Mandatorily Convertible Preferred Stock as Replacement Capital Securities if, in the case of this clause (iii), an accounting standard or interpretive guidance of an existing accounting standard issued by an organization or regulator that has responsibility for establishing or interpreting accounting standards in the United States becomes effective, which, as a result, causes the Corporation to believe that there is more than an insubstantial risk that the failure to do so would result in a reduction in the Corporation’s earnings per share as calculated for financial reporting purposes.

(c) For purposes of Sections 4(a) and 4(b), the Holders whose consent or agreement is required to terminate, amend or supplement the obligations of the Corporation under this Replacement Capital Covenant shall be the Holders of the then-effective Covered Debt as of a record date established by the Corporation that is not more than 30 days prior to the date on which the Corporation proposes that such termination, amendment or supplement becomes effective.

SECTION 5.Miscellaneous. (a) This Replacement Capital Covenant shall be governed by and construed in accordance with the laws of the State of New York.

(b) This Replacement Capital Covenant shall be binding upon the Corporation and its successors and assigns and shall inure to the benefit of the Covered Debtholders as they exist from time-to-time (it being understood and agreed by the Corporation that any Person who is a Covered Debtholder at the time such Person acquires, holds or sells Covered Debt shall retain its status as a Covered Debtholder for so long as the series of long-term indebtedness for borrowed money owned by such Person is Covered Debt and, if such Person initiates a claim or proceeding to enforce its rights under this Replacement Capital Covenant after the Corporation has violated its covenants in Section 2 and before the series of long-term indebtedness for money borrowed held by such Person is no longer Covered Debt, such Person’s rights under this Replacement Capital Covenant shall not terminate by reason of such series of long-term indebtedness for money borrowed no longer being Covered Debt). Other than the Covered Debtholders as provided in the previous sentence, no other Person shall have any rights under this Replacement Capital Covenant or be deemed a third party beneficiary of this Replacement Capital Covenant. In particular, no holder of the Debentures is a third party beneficiary of this Replacement Capital Covenant, it being understood that such holders may have rights under the Subordinated Indenture.

(c) All demands, notices, requests and other communications to the Corporation under this Replacement Capital Covenant shall be deemed to have been duly given and made if in writing and (i) if served by personal delivery upon the Corporation, on the day so delivered (or, if such day is not a Business Day, the next succeeding Business Day) or (ii) if delivered by registered post or certified mail, return receipt requested, or sent to the Corporation by a national or international courier service, on the date of receipt by the Corporation (or, if such date of receipt is not a Business Day, the next succeeding Business Day), and in each case to the Corporation at the address set forth below, or at such other address as the Corporation may thereafter notify to Covered Debtholders or post on its website (or any other similar electronic platform generally available to the public) as the address for notices under this Replacement Capital Covenant:
