Commercial banks and their securities broker subsidiaries that have agreements
with the Sponsors may make Units available to their customers as their agents. A
portion of the sales charge (equal to the dealer commission referred to above)
will be retained by or remitted to the banks. Under the Glass-Steagall Act,
banks are prohibited from underwriting Units; however, the Glass-Steagall Act
permits banks to act as agents of their customers on a disclosed basis and
federal banking regulators have approved arrangements similar to those
arrangements. In addition, state securities laws on this issue may differ from
the interpretations of federal law expressed above and banks and financial
institutions may be required to register as dealers pursuant to state law.
The minimum purchase of one or both Trusts on any day is $250.
