Under Rule 15c6-1 of 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 Series E Term Preferred Stock on the date of pricing or the next two succeeding business days will be required, by virtue of the fact that the Series E Term Preferred Stock initially will settle T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Series E Term Preferred Stock who wish to trade the Series E Term Preferred Stock on the date of pricing or the next four succeeding business days should consult their own advisor.

This pricing term sheet, the Preliminary Prospectus and pricing press release are not offers to sell or the solicitation of offers to buy, nor will there be any sale of the Series E Term Preferred Stock referred to in this pricing term sheet, in any jurisdiction where such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of such jurisdiction.

A shelf registration statement relating to these securities is on file with and has been declared effective by the U.S. Securities and Exchange Commission.
