It is expected that delivery of the Debentures will be made against payment therefor on or about June 24, 2019, which will be the fifth business day following the date of pricing of the Debentures. Under Rule 15c6-1 of the Securities Exchange Act of 1934, 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, by virtue of the fact that the Debentures initially will settle in T+5, purchasers who wish to trade the Debentures on the date of pricing of the Debentures or on the two succeeding business days should specify an extended settlement cycle at the time they enter into any such trade to prevent failed settlement and should consult their own advisors.
