| If the applicable Conditions to Redemption are not satisfied on the 2036 Scheduled Maturity Date, then the 2036 Notes will not become due and payable on such date, interest will continue to accrue at the applicable rate set forth above and be payable on the interest payment dates and, following such 2036 Scheduled Maturity Date, the 2036 Notes will become due and payable on the earlier of (i) 10 business days after the applicable Conditions to Redemption become satisfied and would continue to be satisfied if the final redemption payment were made (so long as such requirements continue to be so satisfied on such 10th business day), and (ii) the date on which a Winding-Up occurs with respect to the Issuer (such date, as applicable, the “2036 Final Maturity Date”). | If the applicable Conditions to Redemption are not satisfied on the 2056 Scheduled Maturity Date, then the 2056 Notes will not become due and payable on such date, interest will continue to accrue at the applicable rate set forth above and be payable on the interest payment dates and, following such 2056 Scheduled Maturity Date, the 2056 Notes will become due and payable on the earlier of (i) 10 business days after the applicable Conditions to Redemption become satisfied and would continue to be satisfied if the final redemption payment were made (so long as such requirements continue to be so satisfied on such 10th business day), and (ii) the date on which a Winding-Up occurs with respect to the Issuer (such date, as applicable, the “2056 Final Maturity Date”). | |||||||||||||

| If, at any time in the six months prior to the 2036 Scheduled Maturity Date, the Issuer does not (or would not after giving effect to the repayment of the 2036 Notes) satisfy the Conditions to Redemption, the Issuer will become subject to a “Replacement Capital Obligation.” | If, at any time in the six months prior to the 2056 Scheduled Maturity Date, the Issuer does not (or would not after giving effect to the repayment of the 2056 Notes) satisfy the Conditions to Redemption, the Issuer will become subject to a “Replacement Capital Obligation.” | |||||||||||||
| Under the Replacement Capital Obligation, the Issuer would be required to promptly begin using Commercially Reasonable Efforts, subject to the occurrence of a Market Disruption Event, to raise a sufficient amount of proceeds to repay the 2036 Notes from issuance of new capital instruments (other than common equity or common equity-linked instruments) having equal or better capital treatment as the 2036 Notes under the Group Rules (in each case, subject to the terms and conditions described in the “Description of Notes”).

* An explanation of the significance of ratings may be obtained from the rating agencies. Generally, rating agencies base their ratings on such material and information, and such of their own investigations, studies and assumptions, as they deem appropriate. The anticipated ratings of the notes should be evaluated independently from similar ratings of other securities. A credit rating of a security is not a recommendation to buy, sell or hold securities and may be subject to review, revision, suspension, reduction or withdrawal at any time by the assigning rating agency.
**It is expected that delivery of the Notes will be made against payment therefor on or about June 9, 2026, which is the fifth business day following the date hereof (such settlement cycle being referred to as ‘‘T+5’’). Pursuant to Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to their date of delivery may be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the Notes who wish to trade such Notes earlier than the business day preceding settlement should consult their own advisors.
