PART I.

Subject to the provisions of Part II hereof, all the

"32. "Supplemental Reference Trust Agree-

tially specified in a Reference Trust Agree-
ment."
and to insert the following language in renum-
bered paragraph (6) defining "Bonds" after each
reference to Reference Trust Agreement:
"and Supplemental Reference Trust
Agreements"
and to replace the last word in renumbered
paragraph (6) defining "Bonds" with the word
-3-
"relate" and to insert the following language
in renumbered paragraph (10) defining "Contract
Bonds" after the reference to Reference Trust
Agreement and redesignate the subsequent clause

"(ii) Bonds listed in schedules of

ments"
and to add the following language to the end of
renumbered paragraph (28) defining
"Securities":
"deposited in trust and listed on a

B. Article II, entitled "Deposit of Securities; Accep-
tance of Trust; Issuance of Units; Form of Certifi-
▇▇▇▇▇", shall be amended to add a new Section 2.05
entitled "Deposit of Additional Securities" to read
as follows:
"From time to time and in the discre-
tion of the Depositor, the Depositor
may make deposits of Additional Secu-
rities duly endorsed in blank or ac-
companied by all necessary instruments
of assignment and transfer in proper
form (or contracts to purchase Addi-
-4-
tional Securities and cash or an ir-
revocable letter of credit in an
amount necessary to consummate the
purchase of any Additional Securities
pursuant to such contracts
("Additional Contract Securities"))
and Cash (as defined below), if Cash
is an asset of the Trust immediately
prior to the supplemental deposit,
provided that each deposit of Addi-
tional Securities and Cash, if any,
deposited during the 90-day period
following the first deposit of Securi-
ties in the Trust shall replicate, to
the extent practicable as hereinafter
provided, the Securities (including
Contract Bonds) and shall exactly rep-
licate Cash (other than Cash to be
distributed only to the Sponsor or in
respect of Units issued and outstand-
ing prior to the deposit) held in the
Trust immediately prior to each such
deposit; and, provided further that
each deposit of Additional Securities
and Cash, if any, subsequent to such
90-day period shall exactly replicate
the Securities (including Contract
Bonds) and Cash (other than Cash to be
distributed only to the Sponsor or in
respect of Units issued and outstand-
ing prior to the deposit) held in the
Trust immediately prior to each such
deposit. For purposes of this Section
2.05 Cash means cash on hand in the
Trust and/or cash receivable by the
Trust as of the date of the supplemen-
tal deposit in respect of a coupon
date which has occurred on or before
the date of such supplemental deposit,
reduced by payables and accrued ex-
penses on such date, but shall not in-
clude cash received on any Security
which is allocable to the amount paid
to the Unit Holders of record on the
first settlement date for the Trust.
-5-
Accordingly, for a deposit subsequent to
the 90-day period following the first deposit
of Securities:
(1) Any Additional Bonds included in a
deposit shall be identical to Bonds held in the
Trust immediately prior to the deposit and in
face amounts such that (i) the face amount of
Additional Bonds of a particular issue included
in a deposit divided by (ii) the aggregate of
the face amounts of all Additional Bonds in-
cluded in the deposit results in a fraction
which is the same as the fraction resulting
from division of (iii) the aggregate face
amount of the Bonds of the same issue held in
the Trust divided by (iv) the aggregate face
amount of all Bonds held in the Trust immedi-
ately prior to the deposit;
(2) Any deposit of Additional Securities
shall be accompanied by Cash in an amount bear-
ing the same ratio to the aggregate face amount
of all Additional Bonds in the deposit as the
Cash held in the Trust immediately prior to the
deposit bears to the aggregate face amount of
all Bonds held in the Trust immediately prior
to the deposit, exclusive of Cash held in the
Trust and designated for distribution only to
the Sponsor or with respect to Units issued and
outstanding prior to the deposit; and
(3) Any Additional Deposited Units in-
cluded in a deposit shall be identical with De-
posited Units then held in the Trust and shall
be in numbers determined by multiplying the
number of Deposited Units with respect to a
particular prior series of the National Munici-
pal Trust held in the Trust immediately prior
to the deposit by the fraction obtained by di-
viding the face amount of all Additional Bonds
included in the deposit by the face amount of
all Bonds included in the Trust immediately
prior to the deposit;
and for a deposit during the 90-day period fol-
lowing the first deposit of Securities in the
Trust, the rules stated in paragraphs (1), (2)
and (3) of this Section 2.05 shall apply ex-
-6-
cept that any Additional Securities (including
Additional Contract Securities) need be only
substantially similar (rather than identical
to) Securities held in the Trust immediately
prior to the deposit and the proportionality
requirements need be met only to the extent
practicable. Without limiting the generality
of the phrase "to the extent practicable", if
the Depositor specifies a minimum face amount
of a Bond or minimum number of Deposited Units
with respect to a particular trust to be in-
cluded in a deposit and such minimum require-
ment cannot be met or if a Security identical
to a Security held in the Trust is not readily
obtainable, substitution of other substantially
similar Securities (including Securities of an
issue originally deposited) in order to meet
the foregoing proportionality requirements
shall be considered as a meeting of such re-
quirements "to the extent practicable".
Each deposit of Additional Securities shall be
listed in and made in accordance with a Supple-
mentary Schedule to the Reference Trust Agree-
ment stating the date of such deposit and the
number of Additional Units being issued there-
for. The execution by the Depositor in connec-
tion with the deposit of Additional Securities
of a Supplementary Schedule to the Reference
Trust Agreement shall constitute the approval
by the Depositor as satisfactory in form and
substance of the contracts to be entered into
or assumed by the Trustee with regard to any
Additional Securities listed on such Supplemen-
tary Schedule and authorization to the Trustee
on behalf of the Trust to enter into or assume
such contracts and otherwise to carry out the
terms and provisions thereof or to take other
appropriate action in order to complete the
deposit of the Additional Securities covered
thereby into the Trust."
C. Article III, entitled "Administration of Trust",
shall be amended as follows:
(i) The first part of the first sentence of
Section 3.01 Initial Costs shall be
amended to substitute the following lan-
-7-
guage before the phrase "provided, how-
ever":
"With respect to the Trust, the cost of
the preparation and printing of the Cer-
tificates, Indenture, Registration State-
ment and other documents relating to the
Trust, Federal and State registration fees
and costs, the initial fees and expenses
of the Trustee and Evaluator, legal and
auditing expenses and other out-of-pocket
organizational expenses, to the extent not
borne by the Depositor, shall be paid by
the Trust;"
Section 3.01 shall be further amended to
add the following language:
"To the extent the funds in the Interest
and Principal Accounts of the Trust shall
be insufficient to pay the expenses borne
by the Trust specified in this Sec-
tion 3.01, the Trustee shall advance out
of its own funds and cause to be deposited
and credited to the Interest Account such
amount as may be required to permit pay-
ment of such expenses. The Trustee shall
be reimbursed for such advance in the man-
ner provided in Section 3.05 at the rate
of accrual set forth in the next sentence,
and the provisions of Section 6.04 with
respect to the reimbursement of disburse-
ments for Trust expenses including, with-
out limitation, the lien in favor of the
Trustee therefor, shall apply to the pay-
ment of expenses made pursuant to this
Section. For purposes of calculation of
distributions under Section 3.05 and the
addition provided in clause (4) of Sec-
tion 5.01, the expenses borne by the Trust
pursuant to this Section shall be deemed
to accrue at a daily rate over the time
period specified for their amortization
provided in the Prospectus; provided, how-
ever, that nothing herein shall be deemed
to prevent, and the Trustee shall be enti-
tled to, full reimbursement for any ad-
-8-
vances made pursuant to this Section no
later than the termination of the Trust.
The Depositor will provide the Trustee
with a written estimate of organizational
expenses upon which the Trustee shall be
entitled to rely unless and until a re-
vised written estimate of such expenses is
delivered to the Trustee by the depositor,
in which event the Trustee shall make ap-
propriate adjustments to Unit Value and
the evaluation of the Trust pursuant to
Section 5.01, and to the accrual of such
expenses of purposes of calculating dis-
tributions."
(ii) section 3.05 Distribution shall be amended
by replacing "$1.00" with "$5.00" in the
first and last sentences of the third
paragraph;
(iii) section 3.05 shall be further amended to
add the following paragraph after the end
thereof: "On each Deferred Sales Charge
payment date set forth in the prospectus
for a Trust, the Trustee shall pay the ac-
count created pursuant to Section 3.15 the
amount of the Deferred Sales Charge pay-
able on each such date as stated in the
prospectus for a Trust. Such amount shall
be withdrawn from the Principal Account
and the Income Account from the amounts
therein designated for such purpose or
otherwise deducted from such accounts."
(iv) sections 3.06 A(3) and 3.06B(3) shall be
amended by adding the following: "and any
Deferred Sales Charge paid".
(v) section 3.07 shall be amended by adding
the following at the end thereof: "In or-
der to pay the Deferred Sales Charge, the
Trustee shall sell or liquidate such an
amount of Securities at such time and from
time to time and in such manner as the De-
positor shall direct such that the pro-
ceeds of such sale or liquidation shall be
sufficient to pay the amount required to
Page>
-9-
be paid to the Depositor pursuant to the
Deferred Sales Charge program as set forth
in the prospectus for a Trust."
(vi) section 3.14 Replacement Bond shall be
amended by deleting from part (vi) of the
second sentence the words "in the category
A or better" and inserting after the word
"organization" the words "in the same
category as the Contract Bond which it re-
places";
D. Section 3.15 shall be added as follows:
Section 3.15. Deferred Sales Charge. If the Refer-
ence Trust Agreement and prospectus for a Trust
specifies a Deferred Sales Charge, the Trustee
shall, on the dates specified in and as permitted by
the prospectus, withdraw from the Income Account or
from the Principal Account, as directed by the De-
positor, an amount per Unit specified in the pro-
spectus and credit such amount to a special, non-
Trust account maintained at the Trustee out of which
the Deferred Sales Charge will be distributed to the
Depositor. If the balances in the Income and Prin-
cipal Accounts are insufficient to make any such
withdrawal, the Trustee shall, as directed by the
Depositor, either advance funds in an amount equal
to the proposed withdrawal and be entitled to ▇▇▇▇-
bursement of such advance upon the deposit of addi-
tional monies in the Income Account or the Principal
Account, sell Securities and credit the proceeds
thereof to such special Depositor's Account or
credit Securities in kind to such special Deposi-
tor's Account. Such directions shall identify the
Securities, if any, to be sold or distributed in
kind and shall contain, if the Trustee is directed
by the Depositor to sell a Security, instructions as
to execution of such sales. If a Unit Holder re-
deems Units prior to full payment of the Deferred
Sales Charge, the Trustee shall, if so provided in
the Reference Trust Agreement and prospectus, on the
Redemption Date, withhold from the Redemption Price
payment to such Unit Holder an amount equal to the
unpaid portion of the Deferred Sales Charge as such
amount is certified by the Depositor to the Trustee
prior to the Redemption Date, upon which certifica-
tion the Trustee shall be entitled to rely, and dis-
-10-
tribute such amount to such special Depositor's Ac-
count or, if the Depositor shall purchase such Unit
pursuant to the terms of Section 5.02 hereof, the
Depositor shall pay the Redemption Price for such
Unit less the unpaid portion of the Deferred Sales
Charge. The Depositor may at any time instruct the
Trustee to distribute to the Depositor cash or Secu-
rities previously credited to the special Deposi-
tor's Account.
E. Article V, entitled "Trust Evaluation; Redemption,
Purchase, Transfer, Interchange or Replacement of
Certificates," Section 5.01 Trust Evaluation shall be
amended as follows:
(i) the second sentence of the first paragraph
of Section 5.01 shall be amended by delet-
ing the word "and" appearing immediately
prior to subsection (3) of such sentence
and inserting the following at the end of
such sentence: ", and (4) amounts repre-
senting organizational expenses paid less
amounts representing accrued organiza-
tional expenses of a Trust."
(ii) The following shall be added at the end of
the first paragraph of Section 5.01:
Until the Depositor has informed the
Trustee that there will be no further de-
posits of Additional Securities pursuant
to section 2.05, the Depositor shall pro-
vide the Trustee with written estimates
of (i) the total organizational expenses
to be borne by the Trust pursuant to Sec-
tion 3.01 and (ii) the total number of
Units to be issued in conneciton with the
initial deposit and all anticipated depos-
its of Additional Securities. For pur-
poses of calculating the value of the
Trust and Unit Value, the Trustee shall
treat all such anticipated expenses as
having been paid and all liabilities
therefor as having been incurred, and all
Units as having been issued, in each case
on the date of the Reference Trust Agree-
ment, and, in connection with each such
calculation, shall take into account a pro
-11-
rata portion of such expense and liability
based on the actual number of Units issued
as of the date of such calculation. In
the event the Trustee is informed by the
Depositor of a revision in its estimate of
total expenses or total Units and upon the
conclusion of the deposit of Additional
Securities, the Trustee shall base calcu-
lations made thereafter on such revised
estimates or actual expenses, respec-
tively, but such adjustment shall not af-
fect calculations made prior thereto and
no adjustment shall be made in respect
thereof.
F. Article VI, entitled "Trustee", section 6.01 General
Definition of Trustee's Liabilities, Rights and Du-
ties shall be amended as follows:
(i) Section 6.01(g) shall be amended by delet-
ing the word "originally"
(ii) Section 6.01(g) shall be amended by in-
serting the phrase "including supplemental
deposits, if any, of Securities in the
Trust" after the first reference to
"Trust".
G. Article IX, entitled "Additional Covenants; Miscella-
neous Provisions", Section 9.01 Amendments shall be
amended as follows:
(i) To add the following phrase after the word
"Indenture" in (1):
"except as the result of the deposit of
Additional Securities, as herein provided"
(ii) To add the following phrase after the word
"Bonds" in (2):
"except in the manner permitted by the In-
denture as in effect on the first deposit
of Securities".
