^* It is expected that delivery of the notes will be made to purchasers on or about November 12, 2019, which is the fourth business day following the date of pricing of the notes (such settlement cycle referred to as T+4), through Clearstream Banking S.A. and Euroclear Bank SA/NV. 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 of pricing or succeeding business day will be required, by virtue of the fact that the notes will settle in T+4, to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement; such purchasers should consult their own advisors in this regard.
