**The Notes will be ready for delivery in book-entry form only through the facilities of DTC for the accounts of its participants, including Euroclear Bank SA/NV, as operator of the Euroclear System, and Clearstream Banking, société anonyme, on or about April 5, 2024, which is the third business day following the date of pricing of the Notes (such settlement cycle being referred to as “T+3”). You should be advised that trading of the Notes may be affected by the T+3 settlement. Under Rule 15c6-1 under the Exchange Act, 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 Notes prior to the date that is two business days preceding the settlement date will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the Notes who wish to trade the Notes during such period should consult their own advisor.
