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

**Note: It is expected that delivery of the Notes will be made against payment therefor on or about March 5, 2025, which will be the second business day following the date hereof (such settlement cycle being referred to as “T+2”). Pursuant to Rule 15c6-1 under 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 of the Notes who wish to trade the Notes on the date of pricing will be required, by virtue of the fact that the Notes initially will settle in T+2, to specify an alternate settlement arrangement 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 should consult their advisors.
