*It is expected that delivery of the notes will be made to investors on or about March 2, 2017, which will be the seventh business day following the date hereof (such settlement being referred to as “T+7”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing or the next three succeeding business days will be required, by virtue of the fact that the notes initially settle in T+7, 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 or the next three succeeding business days should consult their own advisors.
