The information in this Term Sheet supplements the Preliminary Prospectus and updates and supersedes the information in the Preliminary Prospectus to the extent it is inconsistent with the information in the Preliminary Prospectus.

Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the units on any date prior to two business days before delivery will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the units who wish to trade the units on any date prior to two business days before delivery should consult their own advisors.
