ENERGY GROWTH TRUST, SERIES 4
Supplement to the Prospectus dated July 15, 1998
Notwithstanding anything to the contrary in the Prospectus, Unit holders
who acquire Units which, as a result of a reduction in the aggregate
underlying value of the Equity 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 but in no event
will the maximum sales charge exceed 5.5% of the Public Offering Price
per Unit.
