** It is expected that delivery of the Preferred Shares will be made in book-entry form only through the facilities of The Depository Trust Company against payment in New York, New York on or about the third business day following the date of this term sheet. Trades of securities in the secondary market generally are required to settle in two business days, referred to as T+2, unless the parties to a trade agree otherwise. Accordingly, by virtue of the fact that the initial delivery of the Preferred Shares will not be made on a T+2 basis, investors who wish to trade the Preferred Shares before the second business day prior to the Settlement Date will be required to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement.
