Supplement to the Prospectus dated March 22, 2000
Notwithstanding anything to the contrary in the Prospectus, Unit holders who
acquire Units of Storage & Networking Portfolio Series which, as a result of a
reduction in the aggregate underlying value of the Securities, are not subject
to an initial sales charge will be subject to the maximum remaining deferred
sales charge (initially $.35 per Unit). In such case the maximum sales charge
may exceed 4.5% of the Public Offering Price per Unit for Storage & Networking
Portfolio Series, but in no event will the maximum sales charge exceed 5.00% of
the Public Offering Price per Unit for Storage & Networking Portfolio Series.
