It is expected that delivery of the Notes will be made against payment therefor
on August 4, 2004, which will be the fifth business day of the date of this
Pricing Supplement. Pursuant to Rule 15c6-1 under the Securities Exchange Act,
trades in the secondary market generally are required to settle in three
business days, unless the parties to any such trade expressly agree otherwise.
Accordingly, the purchasers who wish to trade the Notes on or prior to August 2,
2004 will be required to specify an alternative settlement cycle at the time of
any such trade to prevent a failed settlement. Purchasers of the Notes who wish
to trade the Notes on or prior to August 2, 2004 should consult their own
advisor.
