Under Rule <FONT STYLE="white-space:nowrap">15c6-1</FONT> of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree
otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+7, to specify alternate settlement arrangements at
the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on any date prior to the business day before delivery should consult their own advisers.</TD></TR>
