The issuer expects that delivery of the Junior Subordinated Debentures will be made to investors on or about the Settlement Date specified above, which will be the seventh business day following the date of this term sheet. Under rules of the Securities and Exchange Commission, trades in the secondary market are required to settle in one business day, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Junior Subordinated Debentures offered hereby on any date prior to one business day before the Settlement Date will be required, by virtue of the fact that the Junior Subordinated Debentures initially settle in T+7, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers who wish to trade the Junior Subordinated Debentures on any date prior to one business day before the Settlement Date should consult their advisors.
