** Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle no later than two business days after the trade date, unless the parties to such trade expressly agree otherwise at the time of the trade. Accordingly, purchasers who wish to trade on any date more than two business days prior to delivery of the Notes will be required, by virtue of the fact that the Notes initially will settle in four business days (T+4), to specify alternative settlement arrangements to prevent a failed settlement.
