** It is expected that delivery of the Senior Notes will be made against payment therefor on or about August 22, 2019, which is the fifth business day following the date hereof (such settlement cycle being 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 the Senior Notes on any date prior to the second business day before delivery will be required, by virtue of the fact that the Senior Notes initially will settle in T+5, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the Senior Notes who wish to trade the Senior Notes prior to the second business day before delivery hereunder should consult their own advisors.
