	•  in whole, but not in part, at any time prior to January 15, 2026, within 90 days after the occurrence of a “rating agency event,” a “tax event” or a “regulatory capital event” (as defined in the Preliminary Prospectus Supplement) at a redemption price equal to (i) with respect to a “rating agency event,” 102% of their principal amount and (ii) with respect to a “tax event” or a “regulatory capital event,” their principal amount, in each case plus accrued and unpaid interest (including compounded interest) to, but excluding, the date of redemption.
Option to Defer Interest Payments:	So long as no event of default with respect to the Subordinated Notes has occurred and is continuing, the Company has the right, on one or more occasions, to defer interest payments on the Subordinated Notes for one or more consecutive interest periods for up to five years as described in the Preliminary Prospectus Supplement. The Company may not defer interest beyond the maturity date, any earlier accelerated maturity date arising from an event of default or any other earlier redemption of the Subordinated Notes. During a deferral period, interest will continue to accrue on the Subordinated Notes at the then-applicable rate of the Subordinated Notes described above and deferred interest on the Subordinated Notes will bear additional interest at the then-applicable interest rate of the Subordinated Notes, compounded on each interest payment date, subject to applicable law. If the Company has paid all deferred interest (including compounded interest thereon) on the Subordinated Notes, the Company can again defer interest payments on the Subordinated Notes as described above.
Certain Payment Restrictions Following Deferral of Interest:	At any time when the Company has given notice of its election to defer interest payments on the Subordinated Notes but the related deferral period has not yet commenced or a deferral period is continuing, the Company and its subsidiaries generally may not make payments on or redeem or purchase any shares of its capital stock or any of its debt securities or guarantees that rank upon its liquidation on a parity with or junior to the Subordinated Notes, subject to certain limited exceptions.

** It is expected that delivery of the Subordinated Notes will be made against payment therefor on or about November 19, 2020, which is the third business day following the date hereof (such settlement cycle being referred to as “T+3”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Subordinated Notes on the date of pricing will be required, by virtue of the fact that the Subordinated Notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the Subordinated Notes who wish to trade the Subordinated Notes on the date of pricing should consult their own advisors.
