A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the business day before the delivery of the Notes will be required, by virtue of the fact that the Notes initially will settle T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes on the date of pricing or the next three succeeding business days should consult their own advisor.

The information in the Preliminary Prospectus and in this pricing term sheet is not complete and may be changed. This pricing term sheet, the Preliminary Prospectus and the pricing press release are not offers to sell or the solicitation of offers to buy, nor will there be any sale of the Notes 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.
