the Trust Units shall, to the extent
of the expenses reimbursable to the
Depositor provided below, be borne
by the Unit Holders, provided, however,
that, to the extent all of such costs

therein specified, from the Principal
Account, and pay to the Depositor the
Depositor's reimbursable expenses of
organizing the Trust and sale of the
Trust Units in an amount certified to
the Trustee by the Depositor. If the
balance of the Principal Account is
insufficient to make such withdrawal,
the Trustee shall, as directed by the
Depositor, sell Securities identified
by the Depositor, or distribute to the
Depositor Securities having a value,
as determined under Section 4.01 as
of the date of distribution, sufficient
for such reimbursement. The reimburse-
ment provided for in this section shall
be for the account of the Unitholders of
record at the conclusion of the primary
offering period and shall not be reflected
in the computation of the Unit Value prior
thereto. As used herein, the Depositor's

reimbursable expenses of organizing the
Trust and sale of the Trust Units shall
include the cost of the initial preparation
and typesetting of the registration

and legal and other out-of-pocket expenses
related thereto, but not including the
expenses incurred in the printing of
preliminary prospectuses and prospectuses,
expenses incurred in the preparation and
printing of brochures and other advertising
materials and any other selling expenses.
Any cash which the Depositor has identified
as to be used for reimbursement of
expenses pursuant to this Section shall be
reserved by the Trustee for such purpose
and shall not be subject to distribution or,
unless the Depositor otherwise directs,
used for payment of redemptions in excess
of the per-Unit amount allocable to Units
tendered for redemption. As directed by the
Depositor, the Trustee will advance funds
to the Trust in an amount necessary to
reimburse the Depositor pursuant to this
Section and shall recover such advance
from the sale or sales of Securities at
such time as the Depositor shall direct,
but in no event later than the termination
of the Trust. Repayment of any such advance
shall be secured by a lien on the assets of
the Trust prior to the interest of the Unit
Holders as provided in Section 6.04.
(ii) The third paragraph of Section 3.05
Distribution shall be amended to add the
following sentence at the end thereof:
"The Trustee shall make a special
distribution of the cash balance in the
Income and Principal accounts available

assets of the Trust subsequent to such
distribution would not exceed any
Deferred Sales Charge payable and other
trust expenses."

Section 3.08 Sale of Securities shall be
amended to replace the word "equal" with
