Accordingly, purchasers who wish to trade the notes before the first business day prior to the Settlement Date will be required, by virtue of the fact that the notes initially will settle on a delayed basis, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors with respect to these matters. |
