*Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

**It is expected that delivery of the notes will be made to investors on or about January 18, 2019, which will be the fifth business day following the date hereof (such settlement being referred to as “T+5”). Under Rule 15c6-1 under the Securities and 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 notes on any date prior to the second business day prior to delivery of the notes hereunder may be required, by virtue of the fact that the notes initially settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and such purchasers should consult their own advisors.
