Accordingly, purchasers who wish to trade the Notes on any date prior to one business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify alternate settlement arrangements at the time of any such trade to prevent a failed settlement and should consult their own advisers.
