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

** The Issuer expects that delivery of the Notes will be made against payment therefor on or about October 5, 2021, which will be the fifth business day following the date of this pricing term sheet. This settlement cycle is referred to as “T+5.” 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 notes on the date hereof or the next two succeeding business days will be required, by virtue of the fact that the Notes 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 notes who wish to trade notes on the date hereof or the next two succeeding business days should consult their own advisors.
