Rule 497(d) FT 391
Supplement to the Prospectus dated April 12, 2000
Sales Charge Discount for Eligible Purchasers
Notwithstanding anything to the
contrary in the Prospectus, investors purchasing Units through
registered broker/dealers who charge periodic fees in
lieu of commissions or who charge for financial planning, investment
advisory or asset management services or provide these or
comparable services as part of an investment account where a
comprehensive "wrap fee" or similar charge is imposed will not be
assessed the initial or deferred sales charge as described in the
section entitled "Public Offering" in the Prospectus on the
purchase of Trust Units.
At the time of purchase of Units pursuant to this
provision you may elect to have distributions on your Units reinvested
into additional Units of the Trust or distributed to you in cash. We
reserve the right to limit or deny purchases of Units pursuant to
this provision by investors whose frequent trading activity we
determine to be detrimental to the Trust. Dealers and
other selling agents will not receive a concession on sales
described above, but such sales will be included in determining
whether dealers are eligible to receive additional volume
concessions.
