Series 2025A Junior Subordinated Notes by extending the interest payment period for up to 40 consecutive quarterly periods (each period, commencing on the date that the first such interest payment would otherwise have been made, an “Optional Deferral Period”). A deferral of interest payments may not extend beyond the maturity date of the Series 2025A Junior Subordinated Notes or end on a day other than an Interest Payment Date. Any deferred interest on the Series 2025A Junior Subordinated Notes will accrue additional interest at the Securities Rate from the applicable Interest Payment Date to the date of payment, compounded quarterly (such deferred interest and additional interest accrued thereon, “Additional Interest”), to the extent permitted under applicable law. No interest will be due and payable on the Series 2025A Junior Subordinated Notes until the end of an Optional Deferral Period, except upon a redemption of the Series 2025A Junior Subordinated Notes during such Optional Deferral Period.

At the end of an Optional Deferral Period or on any redemption date, the Company will be obligated to pay all accrued and unpaid interest, including any Additional Interest. Once the Company pays all accrued and unpaid interest payments on the Series 2025A Junior Subordinated Notes, including any Additional Interest, the Company can again defer interest payments on the Series 2025A Junior Subordinated Notes as described above, but not beyond the maturity date of the Series 2025A Junior Subordinated Notes.

The Company is required to provide to the Subordinated Note Indenture Trustee written notice of any optional deferral of interest at least 10 and not more than 60 Business Days prior to the earlier of (1) the next applicable Interest Payment Date or (2) the date, if any, upon which it is required to give notice of such Interest Payment Date or the
