NOTE: Part One of this Prospectus may not be distributed unless accompanied by

In the opinion of counsel, interest income to each Trust and to Unitholders,
with certain exceptions, is exempt under existing law from all Federal income
taxes, but may be subject to state and local taxes. Capital gains, if any, are
subject to Federal tax. 

THE TRUSTS

Each of the captioned series of Insured Municipals Income Trust (the "
Trust") consists of an insured portfolio of interest-bearing obligations
(the "Bonds"or "Securities") issued by or on behalf of
municipalities and other governmental authorities or by certain United States
territories or possessions and their public authorities, the interest on which
is, in the opinion of recognized bond counsel to the issuing governmental
authority, exempt from all Federal income taxes under existing law. Each Unit
represents a fractional undivided interest in the principal and net income of
the Trust (see "Summary of Essential Information"in this Part One and
"The Trust"in Part Two).

which have been purchased by the Sponsor in the secondary market or from the
Trustee after having been tendered for redemption. The profit or loss

bid price of the Bonds in the portfolio of such Trust divided by the number of
Units of such Trust outstanding, plus a sales charge. The sales charge is
based upon the years to average maturity of the Bonds in the portfolio. The
sales charge ranges from 1.5% of the Public Offering Price (1.523% of the
aggregate bid price of the Bonds) for a Trust with a portfolio with less than
two years to average maturity to 5.7% of the Public Offering Price (6.045% of
the aggregate bid price of the Bonds) for a Trust with a portfolio with
sixteen or more years to average maturity. See "Summary of Essential
Information"in this Part One.

PORTFOLIO

In selecting Bonds for the Insured Municipals Income Trust, Series 16, the
following facts, among others, were considered: (i) either the Standard &
Poor's Ratings Group rating of the Bonds was in no case less than
"BBB-" or the Moody's Investors Service, Inc. rating of the Bonds was in no
case less than "Baa", including provisional or conditional ratings,
respectively or, if not rated, the Bonds had, in the opinion of the Sponsor,
credit characteristics sufficiently similar to the credit characteristics of
interest-bearing tax-exempt obligations that were so rated as to be acceptable
for acquisition by the Fund (see "Description of Securities Ratings"
in Part Two), (ii) the prices of the Bonds relative to other Bonds of
comparable quality and maturity, (iii) the availability and cost of insurance
for the prompt payment of principal and interest on the Bonds and (iv) the
diversification of Bonds as to purpose of issue and location of issuer. Since
the date of deposit the rating of certain Bonds in the portfolio may have been
lowered by the appropriate rating agency. Debt rated BBB is regarded as having
an adequate capacity to pay interest and repay principal. Whereas it normally
exhibits adequate protection parameters, adverse economic conditions or
changing circumstances are more likely to lead to a weakened capacity to pay
interest and repay principal for debt in this category than in higher rated
categories. Debt rated BB, B, CCC and CC is regarded, on balance, as
predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and CC the highest degree of speculation. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions. As of December 31, 1994, the Trust consists of 8 issues which are
payable from the income of a specific project or authority. The portfolio is
divided by purpose of issue as follows: Airport, 1 (24%); Escrowed, 3 (31%);
Industrial Revenue, 2 (21%) and Single Family, 2 (24%). The portfolio consists
of 8 Bond issues in 7 states. See "Bond Portfolio"herein and "
Description of Securities Ratings"in Part Two.

In selecting Bonds for the Insured Municipals Income Trust, Series 18, the
following facts, among others, were considered: (i) either the Standard &
Poor's Ratings Group rating of the Bonds was in no case less than "
BBB-"or the Moody's Investors Service, Inc. rating of the Bonds was in no
case less than "Baa", including provisional or conditional ratings,
respectively or, if not rated, the Bonds had, in the opinion of the Sponsor,
credit characteristics sufficiently similar to the credit characteristics of
interest-bearing tax-exempt obligations that were so rated as to be acceptable
for acquisition by the Fund (see "Description of Securities Ratings"
in Part Two), (ii) the prices of the Bonds relative to other Bonds of
comparable quality and maturity, (iii) the availability and cost of insurance
for the prompt payment of principal and interest on the Bonds and (iv) the
diversification of Bonds as to purpose of issue and location of issuer. As of
December 31, 1994, the Trust consists of 7 issues which are payable from the
income of a specific project or authority. The portfolio is divided by purpose
of issue as follows: Escrowed, 4 (32%); Health Care System, 1 (4%);
Multi-Family, 1 (40%) and Single Family, 1 (24%). The portfolio consists of 7
Bond issues in 6 states. See "Bond Portfolio"herein and "

BBB-"or the Moody's Investors Service, Inc. rating of the Bonds was in no

respectively (see "Description of Securities Ratings"in Part Two),
(ii) the prices of the Bonds relative to other Bonds of comparable quality and
maturity, (iii) the availability and cost of insurance for the prompt payment
of principal and interest on the Bonds and (iv) the diversification of Bonds
as to purpose of issue and location of issuer. Debt rated BBB is regarded as
having an adequate capacity to pay interest and repay principal. Whereas it
normally exhibits adequate protection parameters, adverse economic conditions
or changing circumstances are more likely to lead to a weakened capacity to
pay interest and repay principal for debt in this category than in higher
rated categories. Debt rated BB, B, CCC and CC is regarded, on balance, as
predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and CC the highest degree of speculation. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions. As of December 31, 1994, the Trust consists of 9 issues which are
payable from the income of a specific project or authority. The portfolio is
divided by purpose of issue as follows: Escrowed, 4 (56%); General Obligation,
1 (7%); Health Care System, 1 (5%); Industrial Revenue 1 (18%); Multi-Family,
1 (2%) and Transportation, 1 (12%). The portfolio consists of 9 Bond issues in
8 states. See "Bond Portfolio"herein and "Description of

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of Insured Municipals Income Trust, Series 16, 17, 18 and
19: 

We have audited the accompanying statements of condition (including the
analyses of net assets) and the related portfolio of Insured Municipals Income
Trust, Series 16, 17, 18 and 19 as of December 31, 1994, and the related
statements of operations and changes in net assets for the three years ended
December 31, 1994. These statements are the responsibility of the Trustee and
the Sponsor. Our responsibility is to express an opinion on such statements
based on our audit. 

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of tax-exempt securities owned at December
31, 1994 by correspondence with the Trustee. An audit also includes assessing
the accounting principles used and significant estimates made by the Trustee
and the Sponsor, as well as evaluating the overall financial statement
presentation. We believe our audit provides a reasonable basis for our
opinion. 

In our opinion, the statements referred to above present fairly, in all
material respects, the financial position of Insured Municipals Income Trust,
Series 16, 17, 18 and 19 as of December 31, 1994, and the results of
operations and changes in net assets for the three years ended December 31,
1994, in conformity with generally accepted accounting principles.

INSURED MUNICIPALS INCOME TRUSTSERIES 16, 17, 18 and 19
Notes to Financial Statements
December 31, 1992, 1993 and 1994 

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Security Valuation - Tax-exempt municipal securities are stated at the value
determined by the Evaluator, American Portfolio Evaluation Services (a
division of a subsidiary of the Sponsor). The Evaluator may determine the
value of the Bonds (1) on the basis of current bid prices of the Bonds
obtained from dealers or brokers who customarily deal in Bonds comparable to
those held by each of the Trusts, (2) on the basis of bid prices for
comparable Bonds, (3) by determining the value of the Bonds by appraisal or
(4) by any combination of the above. The Trusts maintain insurance which
provide for the timely payment when due, of all principal and interest on
Bonds owned by them. Except in cases in which Bonds are in default, or
significant risk of default, this valuation does not include any value
attributable to this insurance feature since the insurance terminates as to
any Bond at the time of its disposition. 

Security Cost - The original cost to each of the Trusts (Series 16, Series 17,
Series 18 and Series 19) was based on the determination by Interactive Data
Services, Inc. of the offering prices of the Bonds on the respective date of
deposit (August 1, 1977, September 6, 1977, October 27, 1977 and January 4,
1978). Since the valuation is based upon the bid prices, such Trusts (Series
16, Series 17, Series 18 and Series 19) recognized downward adjustments of
$274,559, $268,752, $272,018 and $292,618, respectively, on the respective
date of deposit resulting from the difference between the bid and offering
prices. These downward adjustments were included in the aggregate amount of
unrealized depreciation reported in the financial statements for each Trust
for the period ended June 30, 1978. 

Unit Valuation - The redemption price per Unit is the pro rata share of each
Unit in each Trust based upon (1) the cash on hand in such Trust or monies in
the process of being collected, (2) the Bonds in such Trust based on the value
determined by the Evaluator and (3) interest accrued thereon, less accrued
expenses of the Trust, if any. 

Unitholder is considered to be the owner of a pro rata portion of such Trust
and, accordingly, no provision has been made for Federal income taxes. 

Other - Income and expenses are recorded on the accrual basis of accounting.
Any realized gains or losses from securities transactions are reported on an
identified cost basis. 

NOTE 2 - PORTFOLIO 

Ratings - The source of all ratings, exclusive of those designated N/R or * is
Standard & Poor's Ratings Group. Ratings marked * are by Moody's Investors
Service, Inc. as these Bonds are not rated by Standard & Poor's Ratings Group
or Moody's Investors Service, Inc. N/R indicates that the Bond is not rated by
Standard & Poor's Ratings Group or Moody's Investors Service, Inc. The ratings
shown represent the latest published ratings of the Bonds. For a brief
description of rating symbols and their related meanings, see "Description
of Securities Ratings"in Part Two.

Redemption Feature - There is shown under this heading the year in which each
issue of Bonds is initially or currently callable and the call price for that
year. Each issue of Bonds continues to be callable at declining prices
thereafter (but not below par value) except for original issue discount Bonds
which are redeemable at prices based on the issue price plus the amount of
original issue discount accreted to redemption date plus, if applicable, some
premium, the amount of which will decline in subsequent years. "S.F."
indicates a sinking fund is established with respect to an issue of Bonds.
Redemption pursuant to call provisions generally will, and redemption pursuant
to sinking fund provisions may, occur at times when the redeemed Bonds have an
offering side evaluation which represents a premium over par. To the extent
that the Bonds were deposited in a Trust at a price higher than the price at
which they are redeemed, this will represent a loss of capital when compared
with the original Public Offering Price of the Units. Conversely, to the
extent that the Bonds were acquired at a price lower than the redemption
price, this will represent an increase in capital when compared with the
original Public Offering Price of the Units. Distributions will generally be
reduced by the amount of the income which would otherwise have been paid with
respect to redeemed Bonds and there will be distributed to Unitholders the
principal amount in excess of $1 per Unit semi-annually and any premium
received on such redemption. However, should the amount available for
distribution in the Principal Account exceed $10.00 per Unit, the Trustee will
make a special distribution from the Principal Account on the next succeeding
monthly distribution date to holders of record on the related monthly record
date. The Estimated Current Return in this event may be affected by such
redemptions. For the Federal tax effect on Unitholders of such redemptions and
resultant distributions, see paragraph (3) under "Federal Tax Status of
the Trusts"and "Annual Unit Income and Estimated Current Returns"
in Part Two. 

NOTE 2 - PORTFOLIO (continued) 

Insurance -  Insurance coverage providing for the timely payment when due of
all principal and interest on the Bonds in the Trusts has been obtained by the
Trusts or by one of the Preinsured Bond Insurers (as indicated in the Bond
name). Such insurance does not guarantee the market value of the Bonds or the
value of the Units. For Bonds covered under the Trust's insurance policy the
insurance is effective only while Bonds thus insured are held in the Trusts
and the insurance premium, which is a Trust obligation, is paid on a monthly
basis. The premium for insurance which has been obtained from various
insurance companies by the issuer of the Bond involved is payable by the
issuer. Insurance expense for the period reflects adjustments for redeemed or
sold Bonds. 

An Accounting and Auditing Guide issued by the American Institute of Certified
Public Accountants states that, for financial reporting purposes, insurance
coverage of the type acquired by the Trust does not have any measurable value
in the absence of default of the underlying Bonds or indication of the
probability of such default. In the opinion of the Evaluator, there is no
indication of a probable default of Bonds in the portfolio as of the date of
these financial statements. 

Unrealized Appreciation and Depreciation - An analysis of net unrealized
appreciation (depreciation) at December 31, 1994 is as follows:

</TABLE>




NOTE 3 - OTHER 

Marketability - Although it is not obligated to do so, the Sponsor intends to
maintain a market for Units and to continuously offer to purchase Units at
prices, subject to change at any time, based upon the aggregate bid price of
the Bonds in the portfolio of each Trust, plus interest accrued to the date of
settlement. If the supply of Units exceeds demand, or for other business
reasons, the Sponsor may discontinue purchases of Units at such prices. In the
event that a market is not maintained for the Units, a Unitholder desiring to
dispose of his Units may be able to do so only by tendering such Units to the
Trustee for redemption at the redemption price. 

Cost to Investors - The cost to original investors was based on the
Evaluator's determination of the aggregate offering price of the Bonds per
Unit on the date of an investor's purchase, plus a sales charge of 4.9% of the
public offering price which is equivalent to 5.152% of the aggregate offering
price of the Bonds. The secondary market cost to investors is based on the
Evaluator's determination of the aggregate bid price of the Bonds per Unit on
the date of an investor's purchase plus a sales charge based upon the years to
average maturity of the Bonds in the portfolio. The sales charge ranges from
1.5% of the public offering price (1.523% of the aggregate bid price of the
Bonds) for a Trust with a portfolio with less than two years to average
maturity to 5.7% of the public offering price (6.045% of the aggregate bid
price of the Bonds) for a Trust with a portfolio with sixteen or more years to
average maturity. 

Compensation of Evaluator - The Evaluator receives an annual fee for regularly
evaluating the Trust's portfolio. The fee may be adjusted for increases under
the category "All Services Less Rent of Shelter"in the Consumer Price
Index.

FIRST FAMILY OF TRUSTS

INSURED MUNICIPALS 
INCOME TRUST 

PROSPECTUS 
Part Two

In the opinion of counsel, interest income to the Trust and to Unitholders,
with certain exceptions, is excludable under existing law from gross income
for Federal income taxes, but may be subject to state and local taxes. Capital
gains, if any, are subject to Federal tax. 

The Trust. The Trust consists of a series of National unit investment trusts
issued under the name Insured Municipals Income Trust (and including the
various series of the Discount Series, the Limited Maturity Series, the
Intermediate Series and the Short Intermediate Series) or under the name The
First National Dual Series Tax-Exempt Bond Trust. Each Trust consists of
interest-bearing obligations issued by or on behalf of municipalities and
other governmental authorities or issued by certain United States territories
or possessions and their public authorities, the interest on which is, in the
opinion of recognized bond counsel to the issuing governmental authority,
exempt from all Federal income taxes under existing law (the "Bonds"
or "Securities"). The objectives of the Trust are Federally tax-exempt
income and conservation of capital through an investment in a diversified,
insured portfolio of tax-exempt Bonds. The payment of interest and the
preservation of principal are, of course, dependent upon the continuing
ability of the issuers and/or obligors of the Bonds and of the insurers
thereof to meet their respective obligations. There is no assurance that the
Trust's objectives will be met. The Securities in the Discount Series were
acquired at prices which resulted in each Discount Series portfolio, as a
whole, being purchased at a deep discount from the aggregate par value of such
Securities. Gains based upon the difference, if any, between the value of the
Securities at maturity, redemption or sale and their purchase price at a
market discount (plus earned original issue discount) will constitute taxable
ordinary income with respect to a Unitholder. 

The Trust and "AAA"Rating. Insurance guaranteeing the payments of
principal and interest, when due, on the Securities in the portfolio of the
Trust has been obtained from a municipal bond insurance company either by the
Trust, by a prior owner of the Bonds, by the issuer of the Bonds involved or
by the Sponsor prior to the deposit of the Bonds in the Trust. All issues of
the Trust are insured under one or more insurance policies obtained by the
Trust, if any, except for certain issues of certain Trusts for which insurance
has been obtained by the issuer of the Bonds involved, by a prior owner of the
Bonds or by the Sponsor prior to the deposit of such Bonds in the Trust.
Insurance obtained by the Trust, if any, applies only while Bonds are retained
in the Trust while insurance obtained by a Bond issuer is effective so long as
such Bonds are outstanding. The Trustee, upon the sale of a Bond insured under
an insurance policy obtained by the Trust, has a right to obtain from the
insurer involved permanent insurance for such Bond upon the payment of a
single predetermined insurance premium and any expenses related thereto from
the proceeds of the sale of such Bond. Insurance relates only to the Bonds in
the Trust and not to the Units offered hereby or to the market value thereof.
As a result of such insurance, the Units of the Trust received a rating of
"AAA"by Standard & Poor's Ratings Group on the date the Trust was
created. Standard & Poor's Ratings Group has indicated that this rating is not
a recommendation to buy, hold or sell Units nor does it take into account the
extent to which expenses of the Trust or sales by the Trust of Bonds for less
than the purchase price paid by the Trust will reduce payment to Unitholders
of the interest and principal required to be paid on such Bonds. See "
Insurance on the Bonds"on page 5. No representation is made as to any
insurer's ability to meet its commitments. 

Public Offering Price. The secondary market Public Offering Price will be
equal to the aggregate bid price of the Securities in the Trust and cash, if
any, in the Principal Account held or owned by the Trust plus the sales charge
referred to under "Public Offering". In addition, for Insured
Municipals Income Trust 152nd Insured Multi-Series and subsequent series and
Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 213 and subsequent series, the Public Offering Price will include
Purchased Interest and accrued interest, if any. If the Bonds in the Trust
were available for direct purchase by investors, the purchase price of the
Bonds would not include the sales charge included in the Public Offering Price
of the Units.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND

ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE. 

This Prospectus is dated as of the date of the Prospectus Part I accompanying
this Prospectus Part II. 

Van Kampen American Capital

THE TRUST 

Each series of Insured Municipals Income Trust and The First National Dual
Series Tax-Exempt Bond Trust (Insured Series) (the "Trust") was
created under the laws of the State of New York pursuant to a Trust Agreement
(the "Trust Agreement"), between Van Kampen American Capital
Distributors, Inc., as Sponsor, American Portfolio Evaluation Services, a
division of Van Kampen American Capital Investment Advisory Corp., as
Evaluator, and The Bank of New York, as Trustee, or their respective
predecessors. 

The Trust consists of a portfolio of interest-bearing obligations issued by or
on behalf of states and territories of the United States, and political
subdivisions and authorities thereof, the interest on which is, in the opinion
of recognized bond counsel to the issuing authorities, excludable from gross
income for Federal income tax under existing law, but may be subject to state
and local taxes. Unless otherwise terminated as provided therein, the Trust
Agreement for all series except the Limited Maturity, Intermediate and Short
Intermediate Series will terminate at the end of the calendar year prior to
the fiftieth anniversary of its execution, while the Trust Agreement for the
Limited Maturity, Intermediate and Short Intermediate Series will terminate at
the end of the calendar year prior to the twentieth anniversary of its
execution. 

The portfolio of certain Trusts (including the Discount Series) may consist of
bonds that were purchased at a "market"discount from par value at
maturity. The coupon interest rates on the discount bonds at the time they
were purchased and deposited in such Trust were lower than the current market
interest rates for newly issued bonds of comparable rating and type. If such
interest rates for newly issued comparable bonds increase, the market discount
of previously issued bonds will become greater, and if such interest rates for
newly issued comparable bonds decline, the market discount of previously
issued bonds will be reduced, other things being equal. Investors should also
note that the value of bonds purchased at a market discount will increase in
value faster than bonds purchased at a market premium if interest rates
decrease. Conversely, if interest rates increase, the value of bonds purchased
at a market discount will decrease faster than bonds purchased at a market
premium. In addition, if interest rates rise, the prepayment risk of higher
yielding, premium bonds and the prepayment benefit for lower yielding,
discount bonds will be reduced. A bond purchased at a market discount and held
to maturity will have a larger portion of its total return in the form of
taxable income and capital gain and less in the form of tax-exempt interest
income than a comparable bond newly issued at current market rates. See "
Tax Status."Market discount attributable to interest changes does not
indicate a lack of market confidence in the issue. Neither the Sponsor nor the
Trustee shall be liable in any way for any default, failure or defect in any
of the Bonds.

Certain of the Bonds in the Trust are "zero coupon"bonds. Zero coupon
bonds are purchased at a deep discount because the buyer receives only the
right to receive a final payment at the maturity of the bond and does not
receive any periodic interest payments. The effect of owning deep discount
bonds which do not make current interest payments (such as the zero coupon
bonds) is that a fixed yield is earned not only on the original investment but
also, in effect, on all discount earned during the life of such obligation.
This implicit reinvestment of earnings at the same rate eliminates the risk of
being unable to reinvest the income on such obligation at a rate as high as
the implicit yield on the discount obligation, but at the same time eliminates
the holder's ability to reinvest at higher rates in the future. For this
reason zero coupon bonds are subject to substantially greater price
fluctuations during periods of changing market interest rates than are
securities of comparable quality which pay interest currently. See note (6) in
"Notes to Portfolio"in Part One of this Prospectus. 

Each Unit initially offered represents a fractional undivided interest in the
principal and net income of the Trust. To the extent that any Units are
redeemed by the Trustee, the fractional undivided interest in the Trust
represented by each unredeemed Unit will increase, although the actual
interest in the Trust represented by such fraction will remain unchanged.
Units will remain outstanding until redeemed upon tender to the Trustee by
Unitholders, which may include the Sponsor or the Underwriters, or until the
termination of the Trust Agreement. Units of the Trusts are not insured by the
FDIC, are not deposits or other obligations of, or guaranteed by, any
depository institution or any government agency and are subject to investment
risk, including possible loss of the principal amount invested.

OBJECTIVES AND SECURITIES SELECTION 

The objectives of the Trust are income exempt from Federal income taxation and
conservation of capital through an investment in a diversified, insured
portfolio of Federal tax-exempt obligations. There is, of course, no guarantee
that the Trust will achieve its objective. The Trust may be an appropriate
investment vehicle for investors who desire to participate in a portfolio of
tax-exempt fixed income securities with greater diversification than they
might be able to acquire individually. In addition, securities of the type
deposited in the Trust are often not available in small amounts. 

Insurance guaranteeing the timely payment, when due, of all principal and
interest on the Bonds in the Trust has been obtained by the Trust from either
AMBAC Indemnity Corporation ("AMBAC Indemnity"), Financial Guaranty
Insurance Company ("Financial Guaranty") or a combination thereof
(collectively, the "Portfolio Insurers") or by the issuer of such
Bonds, by a prior owner of such Bonds, or by the Sponsor prior to the deposit
of such Bonds in the Trust from (1) AMBAC Indemnity or one of its
subsidiaries, American Municipal Bond Assurance Corporation ("AMBAC")
or MGIC Indemnity Corporation ("MGIC Indemnity"), (2) Financial
Guaranty, (3) Municipal Bond Insurance Association ("MBIA"), (4) Bond
Investors Guaranty Insurance Company ("BIG"), (5) National Union Fire
Insurance Company of Pittsburgh, PA. ("National Union"), (6) Capital
Guarantee Insurance Company ("Capital Guaranty"), (7) Capital Market
Assurance Corporation ("CapMAC") and/or (8) Financial Security
Assurance Inc. ("Financial Security"or "FSA") (collectively,
the "Preinsured Bond Insurers") (see "Insurance on the Bonds"
). Insurance obtained by the Trust is effective only while the Bonds thus
insured are held in the Trust. The Trustee has the right to acquire permanent
insurance from a Portfolio Insurer with respect to each Bond insured by the
respective Portfolio Insurer under a Trust portfolio insurance policy.
Insurance relating to Bonds insured by the issuer, by a prior owner of such
Bonds or by the Sponsor is effective so long as such Bonds are outstanding.
Bonds insured under a policy of insurance obtained by the issuer, by a prior
owner, or by the Sponsor from one of the Preinsured Bond Insurers (the "
Preinsured Bonds") are not additionally insured by the Trust. No
representation is made as to any insurer's ability to meet its commitments. 

Neither the Public Offering Price nor any evaluation of Units for purposes of
repurchases or redemptions reflects any element of value for the insurance
obtained by the Trust, if any, unless Bonds are in default in payment of
principal or interest or in significant risk of such default. See "Public
Offering Price". On the other hand, the value, if any, of Preinsured Bond
insurance is reflected and included in the market value of such Bonds. 

In order for bonds to be eligible for insurance, they must have credit
characteristics which would qualify them for at least the Standard & Poor's
Ratings Group rating of "BBB"or at least the Moody's Investors
Service, Inc. rating of "Baa", which in brief represent the lowest
ratings for securities of investment grade (see "Description of Bond
Ratings"). Insurance is not a substitute for the basic credit of an
issuer, but supplements the existing credit and provides additional security
therefor. If an issue is accepted for insurance, a non-cancellable policy for
the prompt payment of interest and principal on the bonds, when due, is issued
by the insurer. Any premium or premiums relating to Preinsured Bond insurance
is paid by the issuer, by a prior owner of such Bonds or by the Sponsor, and a
monthly premium is paid by an Insured Trust for the portfolio insurance, if
any, obtained by such Trust. The Trustee has the right to obtain permanent
insurance from a Portfolio Insurer in connection with the sale of a Bond
insured under the insurance policy obtained from the respective Insurer by the
Trust upon the payment of a single predetermined insurance premium from the
proceeds of the sale of such Bond. Accordingly, any Bond in the Trust is
eligible to be sold on an insured basis. All bonds insured by the Portfolio
Insurers and the Preinsured Bond Insurers received a "AAA"rating by
Standard & Poor's Ratings Group on the date such bonds were deposited in the
Trust. See "Insurance on the Bonds". 

In selecting Bonds for the Trust, the following facts, among others, were
considered by the Sponsor: (a) either the Standard & Poor's Ratings Group
rating of the Bonds was in no case less than "BBB-"or the Moody's
Investors Service, Inc. rating of the Bonds was in no case less than "
Baa"including provisional or conditional ratings, respectively, or, if
not rated, the Bonds had, in the opinion of the Sponsor, credit
characteristics sufficiently similar to the credit characteristics of
interest-bearing tax-exempt obligations that were so rated as to be acceptable
for acquisition by the Trust (see "Description of Bond Ratings"), (b)
the prices of the Bonds relative to other bonds of comparable quality and
maturity, (c) the diversification of Bonds as to purpose of issue and location
of issuer, and (d) the availability and cost of insurance for the prompt
payment of principal and interest, when due, on the Bonds. Subsequent to the
Date of Deposit, a Bond may cease to be rated or its rating may be reduced
below the minimum required as of the Date of Deposit. Neither event requires
elimination of such Bond from the portfolio but may be considered in the
Sponsor's determination as to whether or not to direct the Trustee to dispose
of the Bond (see "Trust Administration Portfolio Administration"). 

To the best knowledge of the Sponsor, there was no litigation pending as of
the Date of Deposit in respect of any Securities which might reasonably be
expected to have a material adverse effect upon the Fund or any of the Trusts.
At any time after the Date of Deposit, litigation may be initiated on a
variety of grounds with respect to Securities in the Fund. Such litigation,
as, for example, suits challenging the issuance of pollution control revenue
bonds under environmental protection statutes, may affect the validity of such
Securities or the tax-free nature of the interest thereon. While the outcome
of litigation of such nature can never be entirely predicted, the Fund has
received or will receive opinions of bond counsel to the issuing authorities
of each Security on the date of issuance to the effect that such Securities
have been validly issued and that the interest thereon is exempt from Federal
income tax. In addition, other factors may arise from time to time which
potentially may impair the ability of issuers to meet obligations undertaken
with respect to the Securities. 

TRUST PORTFOLIO 

Portfolio Concentrations. Certain of the Bonds in the Trust may be general
obligations of a governmental entity that are backed by the taxing power of
such entity. In view of this an investment in the Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. All other Bonds in the Trust are revenue bonds
payable from the income of a specific project or authority and are not
supported by the issuer's power to levy taxes. General obligation bonds are
secured by the issuer's pledge of its faith, credit and taxing power for the
payment of principal and interest. Revenue bonds, on the other hand, are
payable only from the revenues derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise tax or
other specific revenue source. There are, of course, variations in the
security of the different Bonds in the Fund, both within a particular
classification and between classifications, depending on numerous factors. See
"General"for each Trust. 

Certain of the Bonds in the Trust may be obligations which derive their
payment from mortgage loans. Certain of such housing bonds may be FHA insured
or may be single family mortgage revenue bonds issued for the purpose of
acquiring from originating financial institutions notes secured by mortgages
on residences located within the issuer's boundaries and owned by persons of
low or moderate income. In view of this an investment in the Trust should be
made with an understanding of the characteristics of such issuers and the
risks which such an investment may entail. Mortgage loans are generally
partially or completely prepaid prior to their final maturities as a result of
events such as sale of the mortgaged premises, default, condemnation or
casualty loss. Because these bonds are subject to extraordinary mandatory
redemption in whole or in part from such prepayments of mortgage loans, a
substantial portion of such bonds will probably be redeemed prior to their
scheduled maturities or even prior to their ordinary call dates. Extraordinary
mandatory redemption without premium could also result from the failure of the
originating financial institutions to make mortgage loans in sufficient
amounts within a specified time period. Additionally, unusually high rates of
default on the underlying mortgage loans may reduce revenues available for the
payment of principal of or interest on such mortgage revenue bonds. These
bonds were issued under Section 103A of the Internal Revenue Code, which
Section contains certain requirements relating to the use of the proceeds of
such bonds in order for the interest on such bonds to retain its tax-exempt
status. In each case the issuer of the bonds has covenanted to comply with
applicable requirements and bond counsel to such issuer has issued an opinion
that the interest on the bonds is exempt from Federal income tax under
existing laws and regulations. Certain issuers of housing bonds have
considered various ways to redeem bonds they have issued prior to the stated
first redemption dates for such bonds. In connection with the housing Bonds
held by the Trust, the Sponsor at the Date of Deposit was not aware that any
of the respective issuers of such Bonds were actively considering the
redemption of such Bonds prior to their respective stated initial call dates. 

Certain of the Bonds in the Trust may be health care revenue bonds. In view of
this an investment in the Trust should be made with an understanding of the
characteristics of such issuers and the risks which such an investment may
entail. Ratings of bonds issued for health care facilities are often based on
feasibility studies that contain projections of occupancy levels, revenues and
expenses. A facility's gross receipts and net income available for debt may
service be affected by future events and conditions including, among other
things, demand for services and the ability of the facility to provide the
services required, physicians' confidence in the facility, management
capabilities, competition with other health care facilities, efforts by
insurers and governmental agencies to limit rates, legislation establishing
state rate-setting agencies, expenses, the cost and possible unavailability of
malpractice insurance, the funding of Medicare, Medicaid and other similar
third party payor programs, government regulation and the termination or
restriction of governmental financial assistance, including that associated
with Medicare, Medicaid and other similar third party payor programs. Pursuant
to recent Federal legislation, Medicare reimbursements are currently
calculated on a prospective basis utilizing a single nationwide schedule of
rates. Prior to such legislation Medicare reimbursements were based on the
actual costs incurred by the health facility. The current legislation may
adversely affect reimbursements to hospitals and other facilities for services
provided under the Medicare program. Such adverse changes also may adversely
affect the ratings of the Securities held in the portfolio of the Trust;
however, because of the insurance obtained by the Trust, the "AAA"
rating of the Units of the Trust would not be affected. 

Certain of the Bonds in the Trust may be obligations of public utility
issuers, including those selling wholesale and retail electric power and gas.
In view of this an investment in the Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. General problems of such issuers would include the
difficulty in financing large construction programs in an inflationary period,
the limitations on operations and increased costs and delays attributable to
environmental considerations, the difficulty of the capital market in
absorbing utility debt, the difficulty in obtaining fuel at reasonable prices
and the effect of energy conservation. All of such issuers have been
experiencing certain of these problems in varying degrees. In addition,
Federal, state and municipal governmental authorities may from time to time
review existing, and impose additional, regulations governing the licensing,
construction and operation of nuclear power plants, which may adversely affect
the ability of the issuers of certain of the Bonds in the portfolio to make
payments of principal and/or interest on such Bonds. 

Certain of the Bonds in the Trust may be obligations of issuers whose revenues
are derived from the sale of water and/or sewerage services. In view of this
an investment in the Trust should be made with an understanding of the
characteristics of such issuers and the risks which such an investment may
entail. Such bonds are generally payable from user fees. The problems of such
issuers include the ability to obtain timely and adequate rate increases,
population decline resulting in decreased user fees, the difficulty of
financing large construction programs, the limitations on operations and
increased costs and delays attributable to environmental considerations, the
increasing difficulty of obtaining or discovering new supplies of fresh water,
the effect of conservation programs and the impact of "no-growth"
zoning ordinances. All of such issuers have been experiencing certain of these
problems in varying degrees. 

Certain of the Bonds in the Trust may be industrial revenue bonds ("
IRBs"). In view of this an investment in the Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. IRBs have generally been issued under bond
resolutions pursuant to which the revenues and receipts payable under the
arrangements with the operator of a particular project have been assigned and
pledged to purchasers. In some cases, a mortgage on the underlying project may
have been granted as security for the IRBs. Regardless of the structure,
payment of IRBs is solely dependent upon the creditworthiness of the corporate
operator of the project or corporate guarantor. Corporate operators or
guarantors may be affected by many factors which may have an adverse impact on
the credit quality of the particular company or industry. These include
cyclicality of revenues and earnings, regulatory and environmental
restrictions, litigation resulting from accidents or environmentally-caused
illnesses, extensive competition and financial deterioration resulting from a
corporate restructuring pursuant to a leveraged buy-out, takeover or
otherwise. Such a restructuring may result in the operator of a project
becoming highly leveraged which may impact on such operator's creditworthiness
which in turn would have an adverse impact on the rating and/or market value
of such Bonds. Further, the possibility of such a restructuring may have an
adverse impact on the market for and consequently the value of such Bonds,
even though no actual takeover or other action is ever contemplated or
effected. 

Certain of the Bonds in the Trust may be obligations that are secured by lease
payments of a governmental entity (hereinafter called "lease
obligations"). Lease obligations are often in the form of certificates of
participation. In view of this an investment in the Trust should be made with
an understanding of the characteristics of such issuers and the risks which
such an investment may entail. Although the lease obligations do not
constitute general obligations of the municipality for which the
municipality's taxing power is pledged, a lease obligation lease is ordinarily
backed by the municipality's covenant to budget for, appropriate and make the
payments due under the lease obligation. However, certain lease obligations
contain "non-appropriation"clauses which provide that the
municipality has no obligation to make lease payments in future years unless
money is appropriated for such purpose on a yearly basis. A governmental
entity that enters into such a lease agreement cannot obligate future
governments to appropriate for and make lease payments but covenants to take
such action as is necessary to include any lease payments due in its budgets
and to make the appropriations therefor.A governmental entity's failure to
appropriate for and to make payments under its lease obligation could result
in insufficient funds available for payment of the obligations secured
thereby. Although "non-appropriation"lease obligations are secured by
the leased property, disposition of the property in the event of foreclosure
might prove difficult. 

Certain of the Bonds in the Trust may be obligations of issuers which are, or
which govern the operation of, schools, colleges and universities and whose
revenues are derived mainly from ad valorem taxes or for higher education
systems, from tuition, dormitory revenues, grants and endowments. In view of
this an investment in the Trust should be made with an understanding of the
characteristics of such issuers and the risks which such an investment may
entail. General problems relating to school bonds include litigation
contesting the State constitutionality of financing public education in part
from ad valorem taxes, thereby creating a disparity in educational funds
available to schools in wealthy areas and schools in poor areas. Litigation or
legislation on this issue may affect the sources of funds available for the
payment of school bonds in the Trust. General problems relating to college and
university obligations include the prospect of a declining percentage of the
population consisting of "college"age individuals, possible inability
to raise tuitions and fees sufficiently to cover increased operating costs,
the uncertainty of continued receipt of Federal grants and state funding, and
government legislation or regulations which may adversely affect the revenues
or costs of such issuers. All of such issuers have been experiencing certain
of these problems in varying degrees. 

Certain of the Bonds in the Trust may be obligations which are payable from
and secured by revenues derived from the ownership and operation of facilities
such as airports, bridges, turnpikes, port authorities, convention centers and
arenas. In view of this an investment in the Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. The major portion of an airport's gross operating
income is generally derived from fees received from signatory airlines
pursuant to use agreements which consist of annual payments for leases,
occupancy of certain terminal space and service fees. Airport operating income
may therefore be affected by the ability of the airlines to meet their
obligations under the use agreements. The air transport industry is
experiencing significant variations in earnings and traffic, due to increased
competition, excess capacity, increased costs, deregulation, traffic
constraints and other factors, and several airlines are experiencing severe
financial difficulties. The Sponsor cannot predict what effect these industry
conditions may have on airport revenues which are dependent for payment on the
financial condition of the airlines and their usage of the particular airport
facility. Similarly, payment on Bonds related to other facilities is dependent
on revenues from the projects, such as user fees from ports, tolls on
turnpikes and bridges and rents from buildings. Therefore, payment may be
adversely affected by reduction in revenues due to such factors as increased
cost of maintenance, decreased use of a facility, lower cost of alternative
modes of transportation, scarcity of fuel and reduction or loss of rents. 

Certain of the Bonds in the Trust may be obligations which are payable from
and secured by revenues derived from the operation of resource recovery
facilities. In view of this an investment in the Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. Resource recovery facilities are designed to process
solid waste, generate steam and convert steam to electricity. Resource
recovery bonds may be subject to extraordinary optional redemption at par upon
the occurrence of certain circumstances, including but not limited to:
destruction or condemnation of a project; contracts relating to a project
becoming void, unenforceable or impossible to perform; changes in the economic
availability of raw materials, operating supplies or facilities necessary for
the operation of a project or technological or other unavoidable changes
adversely affecting the operation of a project; administrative or judicial
actions which render contracts relating to the projects void, unenforceable or
impossible to perform; or impose unreasonable burdens or excessive
liabilities. The Sponsor cannot predict the causes or likelihood of the
redemption of resource recovery bonds in such a Trust prior to the stated
maturity of the Bonds. 

Bond Redemptions. Because certain of the Bonds in the Trust may from time to
time under certain circumstances be sold or redeemed or will mature in
accordance with their terms and because the proceeds from such events will be
distributed to Unitholders and will not be reinvested, no assurance can be
given that the Trust will retain for any length of time its present size and
composition. Neither the Sponsor nor the Trustee shall be liable in any way
for any default, failure or defect in any Bond. 

Certain of the Bonds in the Trust may be subject to redemption prior to their
stated maturity date pursuant to sinking fund provisions, call provisions or
extraordinary optional or mandatory redemption provisions or otherwise. A
sinking fund is a reserve fund accumulated over a period of time for
retirement of debt. A callable debt obligation is one which is subject to
redemption or refunding prior to maturity at the option of the issuer. A
refunding is a method by which a debt obligation is redeemed, at or before
maturity, by the proceeds of a new debt obligation. In general, call
provisions are more likely to be exercised when the offering side valuation is
at a premium over par than when it is at a discount from par. The exercise of
redemption or call provisions will (except to the extent the proceeds of the
called Bonds are used to pay for Unit redemptions) result in the distribution
of principal and may result in a reduction in the amount of subsequent
interest distributions and it may also offset the current return on Units of
the Trust. The portfolio contains a listing of the sinking fund and call
provisions, if any, with respect to each of the debt obligations.
Extraordinary optional redemptions and mandatory redemptions result from the
happening of certain events. Generally, events that may permit the
extraordinary optional redemption of Bonds or may require the mandatory
redemption of Bonds include, among others: a final determination that the
interest on the Bonds is taxable; the substantial damage or destruction by
fire or other casualty of the project for which the proceeds of the Bonds were
used; an exercise by a local, state or Federal governmental unit of its power
of eminent domain to take all or substantially all of the project for which
the proceeds of the Bonds were used; changes in the economic availability of
raw materials, operating supplies or facilities or technological or other
changes which render the operation of the project for which the proceeds of
the Bonds were used uneconomic; changes in law or an administrative or
judicial decree which renders the performance of the agreement under which the
proceeds of the Bonds were made available to finance the project impossible or
which creates unreasonable burdens or which imposes excessive liabilities,
such as taxes, not imposed on the date the Bonds are issued on the issuer of
the Bonds or the user of the proceeds of the Bonds; an administrative or
judicial decree which requires the cessation of a substantial part of the
operations of the project financed with the proceeds of the Bonds; an
overestimate of the costs of the project to be financed with the proceeds of
the Bonds resulting in excess proceeds of the Bonds which may be applied to
redeem Bonds; or an underestimate of a source of funds securing the Bonds
resulting in excess funds which may be applied to redeem Bonds. The issuer of
certain Bonds in a Trust may have sold or reserved the right to sell, upon the
satisfaction of certain conditions, to third parties all or any portion of its
rights to call Bonds in accordance with the stated redemption provisions of
such Bonds. In such a case the issuer no longer has the right to call the
Bonds for redemption unless it reacquires the rights from such third party. A
third party pursuant to these rights may exercise the redemption provisions
with respect to a Bond at a time when the issuer of the Bond might not have
called a Bond for redemption had it not sold such rights. The Sponsor is
unable to predict all of the circumstances which may result in such redemption
of an issue of Bonds. See "Trust Portfolio"and note (3) in "Notes
to Portfolio"in Part One of this Prospectus. See also the discussion of
single family mortgage and multi-family revenue bonds above for more
information on the call provisions of such bonds. 

ESTIMATED CURRENT RETURNS AND ESTIMATED LONG-TERM RETURNS 

As of the opening of business on the date indicated therein, the Estimated
Current Returns and the Estimated Long-Term Returns for each Trust under the
monthly and semi-annual distribution plans were as set forth under "Per
Unit Information"for the applicable Trust in Part One of this Prospectus.
Estimated Current Returns are calculated by dividing the Estimated Net Annual
Interest Income per Unit by the Public Offering Price. The Estimated Net
Annual Interest Income per Unit will vary with changes in fees and expenses of
the Trustee and the Evaluator and with the principal prepayment, redemption,
maturity, exchange or sale of Securities while the Public Offering Price will
vary with changes in the offering price of the underlying Securities and with
changes in Purchased Interest for those series which contain Purchased
Interest; therefore, there is no assurance that the present Estimated Current
Returns will be realized in the future. Estimated Long-Term Returns are
calculated using a formula which (1) takes into consideration, and determines
and factors in the relative weightings of, the market values, yields (which
takes into account the amortization of premiums and the accretion of
discounts) and estimated retirements of all of the Securities in the Trust and
(2) takes into account the expenses and sales charge associated with each
Trust Unit. Since the market values and estimated retirements of the
Securities and the expenses of the Trust will change, there is no assurance
that the present Estimated Long-Term Returns will be realized in the future.
Estimated Current Returns and Estimated Long-Term Returns are expected to
differ because the calculation of Estimated Long-Term Returns reflects the
estimated date and amount of principal returned while Estimated Current
Returns calculations include only Net Annual Interest Income and Public
Offering Price. 

TRUST OPERATING EXPENSES 

Compensation of Sponsor and Evaluator. The Sponsor will not receive any fees
in connection with its activities relating to the Trust. However, in
connection with certain series of the Trust, American Portfolio Evaluation
Services, a division of Van Kampen American Capital Investment Advisory
Corp.,which is a wholly-owned subsidiary of the Sponsor (the "
Evaluator"), will receive an annual supervisory fee, which is not to
exceed the amount set forth under "Summary of Essential Financial
Information"in Part One of this Prospectus, for providing portfolio
supervisory services for such series. Such fee (which is based on the number
of Units outstanding in the Trust on January 1 of each year) may exceed the
actual costs of providing such supervisory services for such series, but at no
time will the total amount received for portfolio supervisory services
rendered to all series of Insured Municipals Income Trust in any calendar year
exceed the aggregate cost to the Evaluator of supplying such services in such
year. In addition, the Evaluator shall receive an annual evaluation fee in the
amount set forth in "Summary of Essential Financial Information"
(which is based on the outstanding principal amount of Securities on January 1
of each year) for regularly evaluating the Trust's portfolio. Both of the
foregoing fees may be increased without approval of the Unitholders by amounts
not exceeding proportionate increases under the category "All Services
Less Rent of Shelter"in the Consumer Price Index published by the United
States Department of Labor or, if such category is no longer published, in a
comparable category. The Sponsor and the dealers will receive sales
commissions and may realize other profits (or losses) in connection with the
sale of Units as described under "Public Offering". 

Trustee's Fee. For its services, the Trustee will receive a fee from the Trust
based on the aggregate outstanding principal amount of Securities in the Trust
as of the opening of business on January 2 and July 2 of each year as set
forth under "Per Unit Information"for the applicable Trust in Part
One of this Prospectus. Such fee will be computed at the amounts set forth in
Part One to this Prospectus for that portion of the Trust under the
semi-annual distribution plan and for those portions of the Trust representing
monthly and quarterly distribution plans. The Trustee's fees are payable
monthly on or before the fifteenth day of each month from the Interest Account
to the extent funds are available and then from the Principal Account. Such
fees may be increased without approval of the Unitholders by amounts not
exceeding proportionate increases under the category "All Services Less
Rent of Shelter"in the Consumer Price Index published by the United
States Department of Labor or, if such category is no longer published, in a
comparable category. Since the Trustee has the use of the funds being held in
the Principal and Interest Accounts for future distributions, payment of
expenses and redemptions and since such Accounts are non-interest bearing to
Unitholders, the Trustee benefits thereby. Part of the Trustee's compensation
for its services to the Trust is expected to result from the use of these
funds. For a discussion of the services rendered by the Trustee pursuant to
its obligations under the Trust Agreement, see "Rights of Unitholders
Reports Provided"and "Trust Administration". 

Insurance Premiums. The cost of the portfolio insurance obtained by the Trust,
if any, is the amount shown in "Summary of Essential Financial
Information"in Part One of this Prospectus. The premium is payable each
year that the Trust retains the Bonds. Premiums, if any, which are Trust
obligations, are payable monthly by the Trustee on behalf of the Trust. As
Bonds in the portfolio are redeemed by their respective issuers or are sold by
the Trustee, the amount of the premium will be reduced in respect of those
Bonds no longer owned by and held in the Trust. If the Trustee exercises the
right to obtain permanent insurance, the premiums payable for such permanent
insurance will be paid solely from the proceeds of the sale of the related
Bonds. The premiums for such permanent insurance with respect to each Bond
will decline over the life of the Bond. The Trust does not incur any expense
for insurance which has been obtained by an issuer of a Bond, since the
premium or premiums for such insurance have been paid by the respective
issuers of such bonds. Bonds for which insurance has been obtained by the
issuer from one of the Preinsured Bond Insurers are not additionally insured
by the Trust. See "Objectives and Securities Selection". 

Miscellaneous Expenses. The following additional charges are or may be
incurred by the Trust: (a) fees of the Trustee for extraordinary services, (b)
expenses of the Trustee (including legal and auditing expenses) and of counsel
designated by the Sponsor, (c) various governmental charges, (d) expenses and
costs of any action taken by the Trustee to protect the Trust and the rights
and interests of Unitholders, (e) indemnification of the Trustee for any loss,
liability or expenses incurred by it in the administration of the Trust
without negligence, bad faith or willful misconduct on its part, (f) any
special custodial fees payable in connection with the sale of any Bonds in a
Trust and (g) expenditures incurred in contacting Unitholders upon termination
of the Trust. 

The fees and expenses set forth herein are payable out of the Trust. When such
fees and expenses are paid by or owing to the Trustee, they are secured by a
lien on the portfolio of the Trust. If the balances in the Interest and
Principal Accounts are insufficient to provide for amounts payable by the
Trust, the Trustee has the power to sell Securities to pay such amounts. 

INSURANCE ON THE BONDS 

Insurance has been obtained by the Trust or by the issuer of such Bonds, or by
a prior owner of such Bonds, or by the Sponsor prior to the deposit of such
Bonds in the Trust guaranteeing prompt payment of interest and principal, when
due, in respect of the Bonds in the Trust. See "Objectives and Securities
Selection". An insurance policy obtained by the Trust, if any, is
non-cancellable and will continue in force so long as the Trust is in
existence, the respective Portfolio Insurer is still in business and the Bonds
described in such policy continue to be held by the Trust. Any portfolio
insurance premium for the Trust, which is an obligation of the Trust, is paid
by the Trust on a monthly basis. Non-payment of premiums on a policy obtained
by the Trust will not result in the cancellation of insurance but will force
the insurer to take action against the Trustee to recover premium payments due
it. The Trustee in turn will be entitled to recover such payments from the
Trust. Premium rates for each issue of Bonds protected by a policy obtained by
the Trust, if any, are fixed for the life of the Trust. The premium for any
Preinsured Bond insurance has been paid by such issuer, by a prior owner of
such Bonds or the Sponsor and any such policy or policies are non-cancellable
and will continue in force so long as the Bonds so insured are outstanding and
the respective Preinsured Bond Insurer remains in business. If the provider of
an original issuance insurance policy is unable to meet its obligations under
such policy or if the rating assigned to the claims-paying ability of any such
insurer deteriorates, the Portfolio Insurers have no obligation to insure any
issue adversely affected by either of the above described events. 

The aforementioned portfolio insurance obtained by the Trust, if any,
guarantees the timely payment of principal and interest on the Bonds as they
fall due. For the purposes of insurance obtained by the Trust, "when
due"generally means the stated maturity date for the payment of principal
and interest. However, in the event (a) an issuer of a Bond defaults in the
payment of principal or interest on such Bond, (b) such issuer enters into a
bankruptcy proceeding or (c) the maturity of such Bond is accelerated, the
affected Portfolio Insurer has the option, in its sole discretion, after
receiving notice of the earliest to occur of such a default, bankruptcy
proceeding or acceleration to pay the outstanding principal amount of such
Bond plus accrued interest to the date of such payment and thereby retire the
Bond from the Trust prior to such Bond's stated maturity date. The insurance
does not guarantee the market value of the Bonds or the value of the Units.
Insurance obtained by the Trust, if any, is only effective as to Bonds owned
by and held in the Trust. In the event of a sale of any such Bond by the
Trustee, such insurance terminates as to such Bond on the date of sale. 

Pursuant to an irrevocable commitment of the Portfolio Insurers, the Trustee,
upon the sale of a Bond covered under a portfolio insurance policy obtained by
the Trust, has the right to obtain permanent insurance with respect to such
Bond (i.e., insurance to maturity of the Bonds regardless of the indemnity of
the holder thereof) (the "Permanent Insurance") upon the payment of a
single predetermined insurance premium and any expenses related thereto from
the proceeds of the sale of such Bond. Accordingly, any Bond in the Trust is
eligible to be sold on an insured basis. It is expected that the Trustee would
exercise the right to obtain Permanent Insurance only if upon such exercise
the Trust would receive net proceeds (sale of Bond proceeds less the insurance
premium and related expenses attributable to the Permanent Insurance) from
such sale in excess of the sale proceeds if such Bonds were sold on an
uninsured basis. The insurance premium with respect to each Bond eligible for
Permanent Insurance would be determined based upon the insurability of each
Bond as of the Date of Deposit and would not be increased or decreased for any
change in creditworthiness of each Bond. 

The Sponsor believes that the Permanent Insurance option provides an advantage
to the Trust in that each Bond insured by a Trust insurance policy may be sold
out of the Trust with the benefits of the insurance attaching thereto. Thus,
the value of the insurance, if any, at the time of sale, can be realized in
the market value of the Bond so sold (which is not the case in connection with
any value attributable to an Insured Trust's portfolio insurance). See "
Public Offering Price". Because any such insurance value may be realized
in the market value of the Bond upon the sale thereof upon exercise of the
Permanent Insurance option, the Sponsor anticipates that (a) in the event the
Trust were to be comprised of a substantial percentage of Bonds in default or
significant risk of default, it is much less likely that the Trust would need
at some point in time to seek a suspension of redemptions of Units than if the
Trust were to have no such option and (b) at the time of termination of the
Trust, if the Trust were holding defaulted Bonds or Bonds in significant risk
of default the Trust would not need to hold such Bonds until their respective
maturities in order to realize the benefits of the Trust's portfolio
insurance. 

Except as indicated below, insurance obtained by the Trust, if any, has no
effect on the price or redemption value of Units. It is the present intention
of the Evaluator to attribute a value for such insurance (including the right
to obtain Permanent Insurance) for the purpose of computing the price or
redemption value of Units if the Bonds covered by such insurance are in
default in payment of principal or interest or in significant risk of such
default. The value of the insurance will be the difference between (i) the
market value of a Bond which is in default in payment of principal or interest
or in significant risk of such default assuming the exercise of the right to
obtain Permanent Insurance (less the insurance premium and related expenses
attributable to the purchase of Permanent Insurance) and (ii) the market value
of such Bonds not covered by Permanent Insurance. It is also the present
intention of the Trustee not to sell such Bonds to effect redemptions or for
any other reason but rather to retain them in the portfolio because value
attributable to the insurance cannot be realized upon sale. See "Public
Offering Price"herein for a more complete description of the Trust's
method of valuing defaulted Bonds and Bonds which have a significant risk of
default. Insurance obtained by the issuer of a Bond is effective so long as
such Bond is outstanding. Therefore, any such insurance may be considered to
represent an element of market value in regard to the Bonds thus insured, but
the exact effect, if any, of this insurance on such market value cannot be
predicted. 

The portfolio insurance policy or policies obtained by the Trust, if any, with
respect to the Bonds in the Trust were issued by one or more of the Portfolio
Insurers. Any other Preinsured Bond insurance policy (or commitment therefor)
was issued by one of the Preinsured Bond Insurers. See "Objectives and
Securities Selection". 

AMBAC Indemnity Corporation ("AMBAC Indemnity") is a
Wisconsin-domiciled stock insurance corporation regulated by the Office of the
Commissioner of Insurance of the State of Wisconsin and licensed to do

and statutory capital of approximately $1,148,000,000 (unaudited) as of March
31, 1994. Statutory capital consists of AMBAC Indemnity's policyholders'
surplus and statutory contingency reserve. AMBAC Indemnity is a wholly owned
subsidiary of AMBAC Inc., a 100% publicly-held company. Moody's Investors
Service, Inc. and Standard & Poor's have both assigned a triple-A
claims-paying ability rating to AMBAC Indemnity. 

Copies of AMBAC Indemnity's financial statements prepared in accordance with
statutory accounting standards are available from AMBAC Indemnity. The address
of AMBAC Indemnity's administrative offices and its telephone number are One
State Street Plaza, 17th Floor, New York, New York, 10004 and (212) 668-0340. 

AMBAC Indemnity has entered into quota share reinsurance agreement under which
a percentage of the insurance underwritten pursuant to certain municipal bond
insurance programs of AMBAC Indemnity has been and will be assumed by a number
of foreign and domestic unaffiliated reinsurers. 

Municipal Bond Investors Assurance Corporation ("MBIA") is the
principal operating subsidiary of MBIA Inc., a New York Stock Exchange listed
company. MBIA, Inc. is not obligated to pay the debts of or claims against
MBIA. MBIA is a limited liability corporation rather than a several liability
association. MBIA is domiciled in the State of New York and licensed to do
business in all fifty states, the District of Columbia and the Commonwealth of
Puerto Rico. As of September 30, 1994, MBIA had admitted assets of $3.3
billion (unaudited), total liabilities of $2.2 billion (unaudited), and total
capital and surplus of $1.1 billion (unaudited) determined in accordance with
statutory accounting practices prescribed or permitted by insurance regulatory
authorities. Copies of MBIA's year end financial statements prepared in
accordance with statutory accounting practices are available from MBIA. The
address of MBIA is 113 King Street, Armonk, New York 10504. 

Effective December 31, 1989, MBIA Inc. acquired Bond Investors Group, Inc. On
January 5, 1990, MBIA acquired all of the outstanding stock of Bond Investors
Group, Inc., the parent of Bond Investors Guaranty Insurance Company (BIG),
now known as MBIA Insurance Corp. of Illinois. Through a reinsurance
agreement, BIG has ceded all of its net insured risks, as well as its unearned
premium and contingency reserves, to MBIA and MBIA has reinsured BIG's net
outstanding exposure. 

Moody's Investors Service, Inc. rates all bond issues insured by MBIA "
Aaa"and short term loans "MIG 1,"both designated to be of the
highest quality. 

Standard and Poor's rates all new issues insured by MBIA "AAA"Prime
Grade. 

The Moody's Investors Service rating of MBIA should be evaluated independently
of the Standard & Poor's rating of MBIA. No application has been made to any
other rating agency in order to obtain additional ratings on the Bonds. The
ratings reflect the respective rating agency's current assessment of the
creditworthiness of MBIA and its ability to pay claims on its policies of
insurance. Any further explanation as to the significance of the above ratings

Financial Security Assurance ("Financial Security"or "FSA")
is a monoline insurance company incorporated on March 16, 1984 under the laws
of the State of New York. The operations of Financial Security commenced on
July 25, 1985, and Financial Security received its New York State Insurance
license on September 23, 1985. Financial Security and its two wholly owned
subsidiaries are licensed to engage in the financial guaranty insurance
business in 49 states, the District of Columbia and Puerto Rico. 

Financial Security and its subsidiaries are engaged exclusively in the
business of writing financial guaranty insurance, principally in respect of
asset-backed and other collateralized securities offered in domestic and
foreign markets. Financial Security and its subsidiaries also write financial
guaranty insurance in respect of municipal and other obligations and reinsure
financial guaranty insurance policies written by other leading insurance
companies. In general, financial guaranty insurance consists of the issuance
of a guaranty of scheduled payments of an issuer's securities, thereby
enhancing the credit rating of those securities, in consideration for payment
of a premium to the insurer. 

Financial Security is 91.6% owned by US West, Inc. and 8.4% owned by The Tokio
Marine and Fire Insurance Co., Ltd. ("Tokio Marine"). Neither U S
WEST, Inc. nor Tokio Marine is obligated to pay the debts of or the claims
against Financial Security. Financial Security is domiciled in the State of
New York and is subject to regulation by the State of New York Insurance
Department. As of March 31, 1993, the total policyholders' surplus and
contingency reserves and the total unearned premium reserve, respectively, of
Financial Security and its consolidated subsidiaries were, in accordance with
generally accepted accounting principles, approximately $479,110,000
(unaudited) and $231,686,000 (unaudited), and the total shareholders' equity
and the total unearned premium reserve, respectively, of Financial Security
and its consolidated subsidiaries were, in accordance with generally accepted
accounting principles, approximately $628,119,000 (unaudited) and $202,493,000
(unaudited). Copies of Financial Security's financial statements may be
obtained by writing to Financial Security at 350 Park Avenue, New York, New
York 10022, Attention: Communications Department. Its telephone number is

Pursuant to an intercompany agreement, liabilities on financial guaranty
insurance written by Financial Security or either of its subsidiaries are
reinsured among such companies on an agreed-upon percentage substantially
proportional to their respective capital, surplus and reserves, subject to
applicable statutory risk limitations. In addition, Financial Security
reinsures a portion of its liabilities under certain of its financial guaranty
insurance policies with unaffiliated reinsurers under various quota share
treaties and on a transaction-by-transaction basis. Such reinsurance is
utilized by Financial Security as a risk management device and to comply with
certain statutory and rating agency requirements; it does not alter or limit
Financial Security's obligations under any financial guaranty insurance
policy. 

Financial Security's claims-paying ability is rated "Aaa"by Moody's
Investors Service, Inc., and "AAA"by Standard & Poor's, Nippon
Investors Service Inc., Duff & Phelps Inc. and Australian Ratings Pty. Ltd.

CapMAC is a New York-domiciled monoline stock insurance company which engages
only in the business of financial guarantee and surety insurance. CapMAC is
licensed in 48 states in addition to the District of Columbia, the
Commonwealth of Puerto Rico and the territory of Guam. CapMAC insures
structured asset-backed, corporate and other financial obligations in the
domestic and foreign capital markets. CapMAC may also provide financial
guarantee reinsurance for structured asset-backed, corporate and municipal
obligations written by other major insurance companies. 

CapMAC's claims-paying ability is rated "Aaa"by Moody's Investors
Service, Inc. ("Moody's"), "AAA"by Standard & Poor's, and
"AAA"by Duff & Phelps, Inc. ("Duff & Phelps"). Such ratings
reflect only the views of the respective rating agencies, are not
recommendations to buy, sell or hold securities and are subject to revision or
withdrawal at any time by such rating agencies. 

CapMAC is wholly owned by CapMAC Holdings Inc. ("Holdings"), a company
that is owned by a group of institutional and other investors, including
CapMAC's management and employees. CapMAC commenced operations on December 24,
1987 as an indirect, wholly-owned subsidiary of Citibank (New York State), a
wholly-owned subsidiary of Citicorp. On June 25, 1992, Citibank (New York
State) sold CapMAC to Holdings (the "Sale"). 

Neither Holdings nor any of its stockholders is obligated to pay any claims
under any surety bond issued by CapMAC or any debts of CapMAC or to make
additional capital contributions. 

CapMAC is regulated by the Superintendent of Insurance of the State of New
York. In addition, CapMAC is subject to regulation by the insurance
departments of the other jurisdictions in which it is licensed. CapMAC is
subject to periodic regulatory examinations by the same regulatory
authorities. 

CapMAC is bound by insurance laws and regulations regarding capital transfers,
limitations upon dividends, investment of assets, changes in control,
transactions with affiliates and consolidations and acquisitions. The amount
of exposure per risk that CapMAC may retain, after giving effect to
reinsurance, collateral or other security, is also regulated. Statutory and
regulatory accounting practices may prescribe appropriate rates at which
premiums are earned and the levels of reserves required. In addition, various
insurance laws restrict the incurrence of debt, regulate permissible
investments of reserves, capital and surplus, and govern the form of surety
bonds. 

CapMAC's obligations under the Surety Bond(s) may be reinsured. Such
reinsurance does not relieve CapMAC of any of its obligations under the Surety
Bond(s). 

THE POLICY IS NOT COVERED BY THE PROPERTY/CASUALTY INSURANCE SECURITY FUND
SPECIFIED IN ARTICLE 76 OF THE NEW YORK INSURANCE LAW. 

As of December 31, 1993 and 1992, CapMAC had statutory capital (which consists
of policyholders' surplus and contingency reserve) of approximately $168
million and $163 million, respectively, and had not incurred any debt
obligations. Article 69 of the New York State Insurance Law requires that
CapMAC establishes and maintains the contingency reserve. 

In addition to its qualified statutory capital and other reinsurance available
to pay claims under its policies, CapMAC has entered into a Stop Loss
Reinsurance Agreement (the "Stop Loss Agreement") with Winterthur
Swiss Insurance Company (the "Reinsurer"), which is rated AAA by
Standard & Poor's and Aaa by Moody's, pursuant to which the Reinsurer will be
required to pay any losses incurred by CapMAC during the term of the Stop Loss
Agreement on the surety bonds covered under the Stop Loss Agreement in excess
of a specified amount of losses incurred by CapMAC under such surety bonds
(such specified amount initially being $100 million and increasing annually by
an amount equal to 66-2/3% of the increase in CapMAC's statutory capital and
surplus) up to an aggregate limit payable under the Stop Loss Agreement of $50
million. The Stop Loss Agreement has an initial term of seven years, is
extendable for one-year periods and is subject to early termination upon the
occurrence of certain events. 

CapMAC also has available a $100,000,000 standby corporate liquidity facility
(the "Liquidity Facility") provided by a syndicate of banks rated A1+
/P1 by Standard & Poor's and Moody's, respectively. The Liquidity Facility is
currently scheduled to expire in June 1997 and may be extended from time to
time. Under the Liquidity Facility CapMAC will be able, subject to satisfying
certain conditions, to borrow funds from time to time in order to enable it to
fund any claim payments or payments made in settlement or mitigation of claims
payments under its surety bonds, including the Policy. 

Copies of CapMAC's financial statements prepared in accordance with statutory
accounting standards, which differ from generally accepted accounting
principles, and filed with the Insurance Department of the State of New York
are available upon request. CapMAC is located at 885 Third Avenue, New York,
New York 10022, and its telephone number is (212) 755-1155. 

In order to be in the Trust, Bonds must be insured by one of the Preinsured
Bond Insurers or be eligible for the insurance being obtained by the Trust. In
determining eligibility for insurance, the Preinsured Bond Insurers; AMBAC
Indemnity and Financial Guaranty, have applied their own standards which
correspond generally to the standards they normally use in establishing the
insurability of new issues of municipal bonds and which are not necessarily
the criteria used in the selection of Bonds by the Sponsor. To the extent the
standards of the Preinsured Bond Insurers; AMBAC Indemnity and Financial
Guaranty, are more restrictive than those of the Sponsor, the previously
stated Trust investment criteria have been limited with respect to the Bonds.
This decision is made prior to the Date of Deposit, as debt obligations not
eligible for insurance are not deposited in the Trust. Thus, all Bonds in the
portfolio are insured either by the Trust or by the issuer of the Bonds, by a
prior owner of such Bonds, or by the Sponsor prior to the deposit of such
Bonds in the Trust. 

Because the Bonds are insured by one of the Portfolio Insurers or one of the
Preinsured Bond Insurers as to the timely payment of principal and interest,
when due, and on the basis of the various reinsurance agreements in effect,
Standard & Poor's has assigned to the Units of the Trust its "AAA"
investment rating. See "Description of Bond Ratings". The obtaining of
this rating by the Trust should not be construed as an approval of the
offering of the Units by Standard & Poor's or as a guarantee of the market
value of the Trust or of the Units. 

The Estimated Current Return and the Estimated Long-Term Return on an
identical portfolio without the insurance obtained by the Trust would have
been higher than the Estimated Current Return and the Estimated Long-Term
Return on the Securities in the Trust after payment of the insurance premium.
An objective of portfolio insurance obtained by the Trust is to obtain a
higher yield on the Trust portfolio than would be available if all the
Securities in such portfolio had Standard & Poor's "AAA"rating and
yet at the same time to have the protection of insurance of prompt payment of
interest and principal, when due, on the Bonds. There is, of course, no
certainty that this result will be achieved. Preinsured bonds in the Trust
which have been insured by the issuer (all of which are rated "AAA"by
Standard & Poor's) may or may not have a higher yield than uninsured bonds
rated "AAA"by Standard & Poor's. In selecting such Bonds for the
portfolio, the Sponsor has applied the criteria hereinbefore described. 

In the event of nonpayment of interest or principal, when due, in respect of a
Bond, AMBAC Indemnity shall make such payment not later than 30 days and
Financial Guaranty shall make such payment within one business day after the
respective insurer has been notified that such nonpayment has occurred or is
threatened (but not earlier than the date such payment is due). The insurer,
as regards any payment it may make, will succeed to the rights of the Trustee
in respect thereof. All policies issued by the Portfolio Insurers and the
Preinsured Bond Insurers are substantially identical insofar as obligations to
the Trust are concerned. 

The Internal Revenue Service has issued a letter ruling which holds in effect
that insurance proceeds representing maturing interest on defaulted municipal
obligations paid to holders of insured bonds, under policy provisions
substantially identical to the policies described herein, will be excludable
from Federal gross income under Section 103(a)(1) of the Internal Revenue Code
to the same extent as if such payments were made by the issuer of the
municipal obligations. Holders of Units in the Trust should discuss with their
tax advisers the degree of reliance which they may place on this letter
ruling. However, Chapman and Cutler, counsel for the Sponsor, has given an
opinion to the effect such payment of proceeds would be excludable from
Federal gross income if, and to the same extent as, such interest would have
been so excludable if paid by the issuer of the defaulted obligations. See
"Tax Status". 

Each Portfolio Insurer is subject to regulation by the department of insurance
in each state in which it is qualified to do business. Such regulation,
however, is no guarantee that each Portfolio Insurer will be able to perform
on its contracts of insurance in the event a claim should be made thereunder
at some time in the future. At the date hereof, it is reported that no claims
have been submitted or are expected to be submitted to any of the Portfolio
Insurers which would materially impair the ability of such company to meet its
commitments pursuant to any contract of bond or portfolio insurance. 

The information relating to each Portfolio Insurer has been furnished by such
companies. The financial information with respect to each Portfolio Insurer
appears in reports filed with state insurance regulatory authorities and is
subject to audit and review by such authorities. No representation is made
herein as to the accuracy or adequacy of such information or as to the absence
of material adverse changes in such information subsequent to the dates
thereof. 

TAX STATUS 

At the time of the closing for each Trust, Chapman and Cutler, counsel for the
Sponsor, rendered an opinion substantially to the effect that: 

(1)Each Trust is not an association taxable as a corporation for Federal
income tax purposes and interest and accrued original issue discount on Bonds
which is excludable from gross income under the Internal Revenue Code of 1986
(the "Code") will retain its status when distributed to Unitholders,
except to the extent such interest is subject to the alternative minimum tax,
an additional tax on branches of foreign corporations and the environmental
tax (the "Superfund Tax"), as noted below; 

(2)Each Unitholder is considered to be the owner of a pro rata portion of the
respective Trust under subpart E, subchapter J of chapter 1 of the Code and
will have a taxable event when such Trust disposes of a Bond, or when the
Unitholder redeems or sells his Units. Unitholders must reduce the tax basis
of their Units for their share of accrued interest received by the respective
Trust, if any, on Bonds delivered after the Unitholders pay for their Units to
the extent that such interest accrued on such Bonds during the period from the
Unitholder's settlement date to the date such Bonds are delivered to the
respective Trust and, consequently, such Unitholders may have an increase in
taxable gain or reduction in capital loss upon the disposition of such Units.
Gain or loss upon the sale or redemption of Units is measured by comparing the
proceeds of such sale or redemption with the adjusted basis of the Units. If
the Trustee disposes of Bonds (whether by sale, payment on maturity,
redemption or otherwise), gain or loss is recognized to the Unitholder. The
amount of any such gain or loss is measured by comparing the Unitholder's pro
rata share of the total proceeds from such disposition with the Unitholder's
basis for his or her fractional interest in the asset disposed of. In the case
of a Unitholder who purchases Units, such basis (before adjustment for earned
original issue discount and amortized bond premium, if any) is determined by
apportioning the cost of the Units among each of the Trust assets ratably
according to value as of the date of acquisition of the Units. The tax cost
reduction requirements of the Code relating to amortization of bond premium
may, under some circumstances, result in the Unitholder realizing a taxable
gain when his Units are sold or redeemed for an amount equal to his original
cost; 

(3)Any proceeds paid under an insurance policy or policies dated the Date of
Deposit, issued to an Insured Trust by AMBAC Indemnity, Financial Guaranty or
a combination thereof with respect to the Bonds which represent maturing
interest on defaulted obligations held by the Trustee will be excludable from
Federal gross income if, and to the same extent as, such interest would have
been so excludable if paid by the issuer of the defaulted obligations provided
that, at the time such policies are purchased, the amounts paid for such
policies are reasonable, customary and consistent with the reasonable
expectation that the issuer of the obligations, rather than the insurer, will
pay debt service on the obligations; and 

(4)Any proceeds paid under individual policies obtained by issuers of Bonds
which represent maturing interest on defaulted obligations held by the Trustee
will be excludable from Federal gross income if, and to the same extent as,
such interest would have been excludable if paid in the normal course by the
issuer of the defaulted obligations provided that, at the time such policies
are purchased, the amounts paid for such policies are reasonable, customary
and consistent with the reasonable expectation that the issuer of the
obligations, rather than the insurer, will pay debt service on the
obligations. 

Sections 1288 and 1272 of the Code provide a complex set of rules governing
the accrual of original issue discount. These rules provide that original
issue discount accrues either on the basis of a constant compound interest
rate or ratably over the term of the Bond, depending on the date the Bond was
issued. In addition, special rules apply if the purchase price of a Bond
exceeds the original issue price plus the amount of original issue discount
which would have previously accrued based upon its issue price (its "
adjusted issue price") to prior owners. The application of these rules
will also vary depending on the value of the Bond on the date a Unitholder
acquires his Units and the price the Unitholder pays for his Units. Investors
with questions regarding these Code sections should consult with their tax
advisers. 

"The Revenue Reconciliation Act of 1993"(the "Tax Act")
subjects tax-exempt bonds to the market discount rules of the Code effective
for bonds purchased after April 30, 1993. In general, market discount is the
amount (if any) by which the stated redemption price at maturity exceeds an
investor's purchase price (except to the extent that such difference, if any,
is attributable to original issue discount not yet accrued), subject to a
statutory de minimis rule. Market discount can arise based on the price a
Trust pays for Bonds or the price a Unitholder pays for his or her Units.
Under the Tax Act, accretion of market discount is taxable as ordinary income;
under prior law the accretion had been treated as capital gain. Market
discount that accretes while a Trust holds a Bond would be recognized as
ordinary income by the Unitholders when principal payments are received on the
Bond, upon sale or at redemption (including early redemption), or upon the
sale or redemption of his or her Units, unless a Unitholder elects to include
market discount in taxable income as it accrues. The market discount rules are
complex and Unitholders should consult their tax advisers regarding these
rules and their application. 

In the case of certain corporations, the alternative minimum tax and the
Superfund Tax for taxable years beginning after December 31, 1986 depends upon
the corporation's alternative minimum taxable income, which is the
corporation's taxable income with certain adjustments. One of the adjustment
items used in computing the alternative minimum taxable income and the
Superfund Tax of a corporation (other than an S Corporation, Regulated
Investment Company, Real Estate Investment Trust, or REMIC) is an amount equal
to 75% of the excess of such corporation's "adjusted current earnings"
over an amount equal to its alternative minimum taxable income (before such
adjustment item and the alternative tax net operating loss deduction). "
Adjusted current earnings"includes all tax exempt interest, including
interest on all of the Bonds in the Fund. Unitholders are urged to consult
their tax advisers with respect to the particular tax consequences to them
including the corporate alternative minimum tax, the Superfund Tax and the
branch profits tax imposed by Section 884 of the Code. 

Counsel for the Sponsor has also advised that under Section 265 of the Code,
interest on indebtedness incurred or continued to purchase or carry Units of a
Trust is not deductible for Federal income tax purposes. The Internal Revenue
Service has taken the position that such indebtedness need not be directly
traceable to the purchase or carrying of Units (however, these rules generally
do not apply to interest paid on indebtedness incurred to purchase or improve
a personal residence). Also, under Section 265 of the Code, certain financial
institutions that acquire Units would generally not be able to deduct any of
the interest expense attributable to ownership of such Units. Investors with
questions regarding this issue should consult with their tax advisers. 

In the case of certain of the Bonds in the Fund, the opinions of bond counsel
indicate that interest on such Bonds received by a "substantial user"
of the facilities being financed with the proceeds of these Bonds, or persons
related thereto, for periods while such Bonds are held by such a user or
related person, will not be excludible from Federal gross income, although
interest on such Bonds received by others would be excludible from Federal
gross income. "Substantial user"and "related person"are
defined under U.S. Treasury Regulations. Any person who believes that he or
she may be a "substantial user"or a "related person"as so
defined should contact his or her tax adviser. 

In the opinion of special counsel to the Fund for New York tax matters, under
existing law, the Fund and each Trust are not associations taxable as
corporations and the income of each Trust will be treated as the income of the
Unitholders under the income tax laws of the State and City of New York. 

All statements of law in the Prospectus concerning exclusion from gross income
for Federal, state or other tax purposes are the opinions of counsel and are
to be so construed. 

At the respective times of issuance of the Bonds, opinions relating to the
validity thereof and to the exclusion of interest thereon from Federal gross
income are rendered by bond counsel to the respective issuing authorities.
Neither the Sponsor nor Chapman and Cutler has made any special review for the
Fund of the proceedings relating to the issuance of the Bonds or of the basis
for such opinions. 

In the case of corporations, the alternative tax rate applicable to long-term
capital gains is 35%, effective for long-term capital gains realized in
taxable years beginning on or after January 1, 1993. For taxpayers other than
corporations, net capital gains are subject to a maximum marginal stated tax
rate of 28%. However, it should be noted that legislative proposals are
introduced from time to time that affect tax rates and could affect relative
differences at which ordinary income and capital gains are taxed. Under the
Code, taxpayers must disclose to the Internal Revenue Service the amount of
tax-exempt interest earned during the year. 

Section 86 of the Code, in general, provides that 50% of Social Security
benefits are includible in gross income to the extent that the sum of "
modified adjusted gross income"plus 50% of the Social Security benefits
received exceeds a "base amount". The base amount is $25,000 for
unmarried taxpayers, $32,000 for married taxpayers filing a joint return and
zero for married taxpayers who do not live apart at all times during the
taxable year and who file separate returns. Modified adjusted gross income is
adjusted gross income determined without regard to certain otherwise allowable
deductions and exclusions from gross income and by including tax-exempt
interest. To the extent that Social Security benefits are includible in gross
income, they will be treated as any other item of gross income. 

In addition, under the Tax Act, for taxable years beginning after December 31,
1993, up to 85% of Social Security benefits are includible in gross income to
the extent that the sum of "modified adjusted gross income"plus 50%
of Social Security benefits received exceeds an "adjusted base amount."
 The adjusted base amount is $34,000 for unmarried taxpayers, $44,000 for
married taxpayers filing a joint return, and zero for married taxpayers who do
not live apart at all times during the taxable year and who file separate
returns. 

Although tax-exempt interest is included in modified adjusted gross income
solely for the purpose of determining what portion, if any, of Social Security
benefits will be included in gross income, no tax-exempt interest, including
that received from a Trust, will be subject to tax. A taxpayer whose adjusted
gross income already exceeds the base amount or the adjusted base amount must
include 50% or 85%, respectively, of his Social Security benefits in gross
income whether or not he receives any tax-exempt interest. A taxpayer whose
modified adjusted gross income (after inclusion of tax-exempt interest) does
not exceed the base amount need not include any Social Security benefits in
gross income. 

For a discussion of the state tax status of income earned on Units of a Trust,
see "Tax Status"for the applicable Trust. Except as noted therein,
the exemption of interest on state and local obligations for Federal income
tax purposes discussed above does not necessarily result in exemption under
the income or other tax laws of any State or City. The laws of the several
States vary with respect to the taxation of such obligations. 

PUBLIC OFFERING 

General. Units are offered at the Public Offering Price. In the secondary
market the Public Offering Price is based on the aggregate bid price of the
Securities in the Trust and includes a sales charge determined in accordance
with the table set forth below, which is based upon the dollar weighted
average maturity of each Trust. In addition, for Insured Municipals Income
Trust, 152nd Insured Multi-Series and subsequent series and Insured Municipals
Income Trust and Investors' Quality Tax-Exempt Trust, Multi-Series 213 and
subsequent series, the Public Offering Price will include Purchased Interest.
For purposes of this computation, Bonds will be deemed to mature on their
expressed maturity dates unless: (a) the Bonds have been called for redemption
or funds or securities have been placed in escrow to redeem them on an earlier
call date, in which case such call date will be deemed to be the date upon
which they mature; or (b) such Bonds are subject to a "mandatory
tender", in which case such mandatory tender will be deemed to be the date
upon which they mature. 

The effect of this method of sales charge computation will be that different
sales charge rates will be applied to each Trust based upon the dollar
weighted average maturity of such Trust's Portfolio, in accordance with the
following schedule: 

<TABLE>
<CAPTION>
Years To Maturity    Sales Charge    Years To Maturity                Sales Charge

</TABLE>

The sales charges in the above table are expressed as a percentage of the
aggregate bid prices of the securities in the Trust. Expressed as a percent of
the Public Offering Price (excluding Purchased Interest for those Trusts which
contain Purchased Interest), the sales charge on a Trust consisting entirely
of a portfolio of Bonds with 15 years to maturity would be 5.10%. 

THE FOLLOWING SECTION "ACCRUED INTEREST (ACCRUED INTEREST TO CARRY),"
APPLIES TO INSURED MUNICIPALS INCOME TRUST, 151st INSURED MULTI-SERIES AND ALL
PRIOR SERIES, AND TO INSURED MUNICIPALS INCOME TRUST AND INVESTORS' QUALITY
TAX-EXEMPT TRUST, MULTI-SERIES 212 AND ALL PRIOR SERIES ONLY. 

Accrued Interest (Accrued Interest To Carry). Accrued interest to carry
consists of two elements. The first element arises as a result of accrued
interest which is the accumulation of unpaid interest on a bond from the last
day on which interest thereon was paid. Interest on Securities in each Trust
is actually paid either monthly, quarterly, if applicable, or semi-annually to
such Trust. However, interest on the Securities in each Trust is accounted for
daily on an accrual basis. Because of this, each Trust always has an amount of
interest earned but not yet collected by the Trustee because of coupons that
are not yet due. For this reason, the Public Offering Price will have added to
it the proportionate share of accrued and undistributed interest to the date
of settlement. 

The second element of accrued interest to carry arises because of the
structure of the Interest Account. The Trustee has no cash for distribution to
Unitholders of a Trust until it receives interest payments on the Securities
in such Trust. The Trustee is obligated to provide its own funds, at times, in
order to advance interest distributions. The Trustee will recover these
advancements when such interest is received. Interest Account balances are
established so that it will not be necessary on a regular basis for the
Trustee to advance its own funds in connection with such interest
distributions. The Interest Account balances are also structured so that there
will generally be positive cash balances and since the funds held by the
Trustee may be used by it to earn interest thereon, it benefits thereby. If a
Unitholder sells or redeems all or a portion of his Units or if the Bonds in a
Trust are sold or otherwise removed or if a Trust is liquidated, he will
receive at that time his proportionate share of the accrued interest to carry
computed to the settlement date in the case of sale or liquidation and to the
date of tender in the case of redemption. 

THE FOLLOWING SECTION "PURCHASED AND ACCRUED INTEREST,"APPLIES TO
INSURED MUNICIPALS INCOME TRUST, 152nd INSURED MULTI-SERIES AND ALL SUBSEQUENT
SERIES, AND TO INSURED MUNICIPALS INCOME TRUST AND INVESTORS' QUALITY
TAX-EXEMPT TRUST, MULTI-SERIES 213 AND ALL SUBSEQUENT SERIES ONLY. 

Purchased and Accrued Interest 

Purchased Interest. Purchased Interest is a portion of the unpaid interest
that has accrued on the Securities from the later of the last payment date on
the Securities or the date of issuance thereof through the First Settlement
Date and is included in the calculation of the Public Offering Price.
Purchased Interest will be distributed to Unitholders as Units are redeemed or
Securities mature or are called. See "Summary of Essential Financial
Information"in Part One of this Prospectus for the amount of Purchased
Interest per Unit for each Trust. Purchased Interest is an element of the
price Unitholders will receive in connection with the sale or redemption of
Units prior to the termination of a Trust. 

Accrued Interest. Accrued Interest is an accumulation of unpaid interest on
securities which generally is paid semi-annually, although a Trust accrues
such interest daily. Because of this, a Trust always has an amount of interest
earned but not yet collected by the Trustee. For this reasons, the Public
Offering Price of Units will have added to it the proportionate share of
accrued interest to the date of settlement. Unitholders will receive on the
next distribution date of a Trust the amount, if any, of accrued interest paid
on their Units. 

As indicated in "Purchased Interest", accrued interest as of the First
Settlement Date includes Purchased Interest. In an effort to reduce the amount
of Purchased Interest which would otherwise have to be paid by Unitholders,
the Trustee may advance a portion of such accrued interest to the Sponsor as
the Unitholder of record as of the First Settlement Date. Consequently, the
amount of accrued interest to be added to the Public Offering Price of Units
will include only accrued interest from the First Settlement Date to the date
of settlement (other than the Purchased Interest already included therein),
less any distributions from the Interest Account subsequent to the First
Settlement Date. See "DistributionsDistribution of Interest and
Principal."

Because of the varying interest payment dates of the Securities, accrued
interest at any point in time will be greater than the amount of interest
actually received by a Trust and distributed to Unitholders. If a Unitholder
sells or redeems all or a portion of his Units, he will be entitled to receive
his proportionate share of the Purchased Interest and accrued interest from
the purchaser of his Units. Since the Trustee has the use of the funds
(including Purchased Interest) held in the Interest Account for distributions
to Unitholders and since such Account is non-interest-bearing to Unitholders,
the Trustee benefits thereby. 

Offering Price. The Public Offering Price of the Units will vary from the
amounts stated under "Summary of Essential Financial Information"in
Part One of this Prospectus in accordance with fluctuations in the prices of
the underlying Securities in the Trust. The price of the Units as of the
opening of business on the date of Part One of this Prospectus was determined
by adding to the determination of the aggregate bid price of the Bonds the
amount of the sales charge expressed as a percentage of the aggregate bid
price of the Securities plus Purchased Interest for those Trusts which contain
Purchased Interest, and dividing the sum so obtained by the number of Units
outstanding. This computation produced a gross profit equal to the sales
charge expressed as a percentage of the Public Offering Price (excluding
Purchased Interest). For secondary market purposes an appraisal and adjustment
with respect to the Trust will be made by the Evaluator as of 4:00 P.M.
Eastern time on days on which the New York Stock Exchange is open for each day
on which any Unit of the Trust is tendered for redemption, and it shall
determine the aggregate value of the Trust as of 4:00 P.M. Eastern time on
such other days as may be necessary. 

The aggregate price of the Securities in the Trust has been and will be
determined on the basis of bid prices: (a) on the basis of current market
prices for the Securities obtained from dealers or brokers who customarily
deal in bonds comparable to those held by the Trust; (b) if such prices are
not available for any particular Securities, on the basis of current market
prices for comparable bonds; (c) by causing the value of the Securities to be
determined by others engaged in the practice of evaluation, quoting or
appraising comparable bonds; or (d) by any combination of the above. Market
prices of the Securities will generally fluctuate with changes in market
interest rates. Unless Bonds are in default in payment of principal or
interest or in significant risk of such default, the Evaluator will not
attribute any value to the insurance obtained by the Trust. 

The Evaluator will consider in its evaluation of Bonds which are in default in
payment of principal or interest or, in the Sponsor's opinion, in significant
risk of such default (the "Defaulted Bonds") the value of the
insurance guaranteeing interest and principal payments. The value of the
insurance will be equal to the difference between (i) the market value of
Defaulted Bonds assuming the exercise of the right to obtain Permanent
Insurance (less the insurance premiums and related expenses attributable to
the purchase of Permanent Insurance) and (ii) the market value of such
Defaulted Bonds not covered by Permanent Insurance. In addition, the Evaluator
will consider the ability of the affected Portfolio Insurer to meet its
commitments under any Trust insurance policy, including the commitments to
issue Permanent Insurance. It is the position of the Sponsor that this is a
fair method of valuing the Bonds and the insurance obtained by the Trust and
reflects a proper valuation method in accordance with the provisions of the
Investment Company Act of 1940. 

Although payment is normally made five business days following the order for
purchase, payment may be made prior thereto. However, delivery of certificates
representing Units so ordered will be made five business days following such
order or shortly thereafter. A person will become the owner of Units on the
date of settlement provided payment has been received. Cash, if any, made
available to the Sponsor prior to the date of settlement for the purchase of
Units may be used in the Sponsor's business and may be deemed to be a benefit
to the Sponsor, subject to the limitations of the Securities Exchange Act of
1934. See "Rights of Unitholders-Redemption of Units"for information
regarding the ability to redeem Units ordered for purchase. 

Unit Distribution. Units repurchased in the secondary market, if any, may be
offered by this Prospectus at the secondary Public Offering Price in the
manner described. 

Broker-dealers or others will be allowed a concession or agency commission in
connection with secondary market transactions in the amount of 70% of the
applicable sales charge as determined using the table found in "Public
Offering General". Certain commercial banks are making Units of the Trust
available to their customers on an agency basis. A portion of the sales charge
(equal to the agency commission referred to above) is retained by or remitted
to the banks. Under the Glass-Steagall Act, banks are prohibited from
underwriting Trust Units; however, the Glass-Steagall Act does permit certain
agency transactions and the banking regulators have not indicated that these
particular agency transactions are not permitted under such Act. In addition,
state securities laws on this issue may differ from the interpretations of
federal law expressed herein and banks and financial institutions may be
required to register as dealers pursuant to state law. The minimum purchase in
the secondary market will be one Unit. 

Broker-dealers of the Trusts and/or others may be eligible to participate in a
program in which such firms receive from the Sponsor a nominal award for each
of their registered representatives who have sold a minimum number of units of
unit investment trusts created by the Sponsor during a specified time period.
In addition, at various times the Sponsor may implement other programs under
which the sales forces of brokers, dealers, and/or others may be eligible to
win other nominal awards for certain sales efforts, or under which the Sponsor
will reallow to any such brokers, dealers, and/or others that sponsor sales
contests or recognition programs conforming to criteria established by the
Sponsor, or participate in sales programs sponsored by the Sponsor, an amount
not exceeding the total applicable sales charges on the sales generated by
such persons at the public offering price during such programs. Also, the
Sponsor in its discretion may from time to time pursuant to objective criteria
established by the Sponsor pay fees to qualifying brokers, dealers or others
for certain services or activities which are primarily intended to result in
sales of Units of the Trust. Such payments are made by the Sponsor out of its
own assets, and not out of the assets of the Trust. These programs will not
change the price Unitholders pay for their Units or the amount that the Trust
will receive from the Units sold. 

The Sponsor reserves the right to reject, in whole or in part, any order for
the purchase of Units and to change the amount of the concession or agency
commission to dealers and others from time to time. 

Sponsor and Dealer Profits. Dealers will receive the gross sales commission as
described under "Public Offering General"above. 

As stated under "Market for Units"below, the Sponsor intends to, and
certain of the dealers may, maintain a secondary market for the Units of the
Trust. In so maintaining a market, the Sponsor or any such dealer will realize
profits or sustain losses in the amount of any difference between the price at
which Units are purchased and the price at which Units are resold. In
addition, the Sponsor or any such dealer will also realize profits or sustain
losses resulting from a redemption of such repurchased Units at a price above
or below the purchase price for such Units, respectively. 

Market for Units. Although they are not obligated to do so, the Sponsor
intends to, and certain of the dealers may, maintain a market for the Units
offered hereby and to offer continuously to purchase such Units at prices,
subject to change at any time, based upon the aggregate bid prices of the
Securities in the portfolio of the Trust, plus Purchased Interest, if any,
plus interest accrued to the date of settlement plus any principal cash on
hand, less any amounts representing taxes or other governmental charges
payable out of the Trust and less any accrued Trust expenses. If the supply of
Units exceeds demand or if some other business reason warrants it, the Sponsor
and/or the dealers may either discontinue all purchases of Units or
discontinue purchases of Units at such prices. In the event that a market is
not maintained for the Units and the Unitholder cannot find another purchaser,
a Unitholder desiring to dispose of his Units may be able to dispose of such
Units only by tendering them to the Trustee for redemption at the Redemption
Price, which is based upon the aggregate bid price of the Securities in the
portfolio of such Trust, plus Purchased Interest, if any, and any accrued
interest. The aggregate bid prices of the underlying Securities in the Trust
are expected to be less than the related aggregate offering prices. See "
Rights of Unitholders  Redemption of Units."A Unitholder who wishes to
dispose of his Units should inquire of his broker as to current market prices
in order to determine whether there is in existence any price in excess of the
Redemption Price and, if so, the amount thereof. 

RIGHTS OF UNITHOLDERS 

Certificates. The Trustee is authorized to treat as the record owner of Units
that person who is registered as such owner on the books of the Trustee.
Ownership of Units of the Trust is evidenced by separate registered
certificates executed by the Trustee and the Sponsor. Certificates are
transferable by presentation and surrender to the Trustee properly endorsed or
accompanied by a written instrument or instruments of transfer. A Unitholder
must sign exactly as his name appears on the face of the certificate with the
signature guaranteed by a participant in the Securities Transfer Agents
Medallion Program ("STAMP") or such other signature guaranty program
in addition to, or in substitution for, STAMP, as may be accepted by the
Trustee. In certain instances the Trustee may require additional documents
such as, but not limited to, trust instruments, certificates of death,
appointments as executor or administrator or certificates of corporate
authority. 

Although no such charge is now made or contemplated, the Trustee may require a
Unitholder to pay a reasonable fee for each certificate reissued (other than
as a result of a change in plan of distribution) or transferred and to pay any
governmental charge that may be imposed in connection with each such transfer
or interchange. Destroyed, stolen, mutilated or lost certificates will be
replaced upon delivery to the Trustee of satisfactory indemnity, evidence of
ownership and payment of expenses incurred. Mutilated certificates must be
surrendered to the Trustee for replacement. 

Distributions of Interest and Principal. Interest received by the Trust,
including that part of the proceeds of any disposition of Securities which
Purchased Interest and/or represents accrued interest, is credited by the
Trustee to the Interest Account. Other receipts are credited to the Principal
Account. All distributions will be net of applicable expenses. The pro rata
share of cash in the Principal Account will be computed as of the semi-annual
record date, and distributions to the Unitholders as of such record date will
be made on or shortly after the fifteenth day of such month. For Insured
Municipals Income Trust, 152nd Insured Multi-Series and subsequent series and
for Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 213 and subsequent series, such computation and distribution will
occur monthly. Proceeds received from the disposition of any of the Securities
after such record date and prior to the following distribution date will be
held in the Principal Account and not distributed until the next distribution
date. The Trustee is not required to pay interest on funds held in the
Principal or Interest Accounts (but may itself earn interest thereon and
therefore benefits from the use of such funds) nor to make a distribution from
the Principal Account unless the amount available for distribution therein
shall equal at least $1.00 per Unit. 

The distribution to the Unitholders as of each record date will be made on the
following distribution date or shortly thereafter and shall consist of an
amount substantially equal to such portion of the Unitholders' pro rata share
of the Estimated Net Annual Unit Income in the Interest Account after
deducting estimated expenses attributable as is consistent with the
distribution plan chosen. Only monthly distributions are available for Insured
Because interest payments are not received by the Trust at a constant rate
throughout the year, such interest distribution may be more or less than the
amount credited to the Interest Account as of the record date. For the purpose
of minimizing fluctuation in the distributions from the Interest Account, the
Trustee is authorized to advance such amounts as may be necessary to provide
interest distributions of approximately equal amounts. The Trustee shall be
reimbursed, without interest, for any such advances from funds in the Interest
Account on the ensuing record date. Persons who purchase Units between a
record date and a distribution date will receive their first distribution on
the second distribution date after the purchase. 

As of the first day of each month, the Trustee will deduct from the Interest
Account and, to the extent funds are not sufficient therein, from the
Principal Account, amounts necessary to pay the expenses of the Trust (as
determined on the basis set forth under "Trust Operating Expenses").
The Trustee also may withdraw from said accounts such amounts, if any, as it
deems necessary to establish a reserve for any governmental charges payable
out of the Trust. Amounts so withdrawn shall not be considered a part of the
Trust's assets until such time as the Trustee shall return all or any part of
such amounts to the appropriate accounts. In addition, the Trustee may
withdraw from the Interest and Principal Accounts such amounts as may be
necessary to cover redemptions of Units by the Trustee. 

Distribution. Distributions of interest received by the Trust, prorated on an
annual basis, will be made semi-annually unless the Unitholder has elected to
receive them monthly or quarterly. Distributions of funds from the Principal
Account will be made on a semi-annual basis, except under the special
circumstances outlined in "Rights of Unitholders Distribution of Interest
and Principal"above. Record dates for monthly distributions will be the
first day of each month, record dates for quarterly distributions will be the
first day of March, June, September and December, and record dates for
semi-annual distributions will be the first day of June and December.
Distributions will be made on the fifteenth day of the month subsequent to the
respective record dates. Unitholders of Insured Municipals Income Trust, 152nd
Insured Multi-Series and subsequent series, and Insured Municipals Income
Trust and Investors' Quality Tax-Exempt Trust, Multi- Series 213 and
subsequent series will receive distributions of income and principal, if any,
on a monthly basis. 

Change of Distribution Option. The plan of distribution selected by a
Unitholder of Insured Municipals Income Trust, 151st Insured Multi-Series and
prior series and Insured Municipals Income Trust and Investors' Quality
Tax-Exempt Trust, Multi-Series 212 and prior series; will remain in effect
until changed. Unitholders purchasing Units in the secondary market will
initially receive distributions in accordance with the election of the prior
owner. Unitholders may change the plan of distribution in which they are
participating. For the convenience of Unitholders, the Trustee will furnish a
card for this purpose; cards may also be obtained upon request from the
Trustee. Unitholders desiring to change their plan of distribution may so
indicate on the card and return it, together with their certificate and such
other documentation that the Trustee may then require, to the Trustee.
Certificates should be sent only by registered or certified mail to minimize
the possibility of their being lost or stolen. If the card and certificate are
properly presented to the Trustee, the change will become effective for all
subsequent distributions. 

Reinvestment Option. Unitholders of the Trust may elect to have each
distribution of interest income, capital gains and/or principal on their Units
automatically reinvested in shares of any of the open ended mutual funds
(except for B Shares) listed under "Trust Administration Sponsor"
which are registered in the Unitholder's state of residence. Such mutual funds
are hereinafter collectively referred to as the "Reinvestment Funds."

Each Reinvestment Fund has investment objectives which differ in certain
respects from those of the Trust. The prospectus relating to each Reinvestment
Fund describes the investment policies of such fund and sets forth the
procedures to follow to commence reinvestment. A Unitholder may obtain a
prospectus for the respective Reinvestment Funds from Van Kampen American
Capital Distributors, Inc. at One Parkview Plaza, Oakbrook Terrace, Illinois
60181. Texas residents who desire to reinvest may request that a broker-dealer
registered in Texas send the prospectus relating to the respective fund. 

After becoming a participant in a reinvestment plan, each distribution of
interest income, capital gains and/or principal on the participant's Units
will, on the applicable distribution date, automatically be applied, as
directed by such person, as of such distribution date by the Trustee to
purchase shares (or fractions thereof) of the applicable Reinvestment Fund at
a net asset value as computed as of the close of trading on the New York Stock
Exchange on such date, plus a sales charge of $1.00 per $100 of reinvestment
except if the participant selects the Van Kampen Merritt Money Market Fund or
the Van Kampen Merritt Tax Free Money Market in which case no sales charge
applies. A minimum of one-half of such sales charge would be paid to Van
Kampen American Capital Distributors, Inc. 

Confirmations of all reinvestments by a Unitholder into a Reinvestment Fund
will be mailed to the Unitholder by such Reinvestment Fund. 

A participant may at any time prior to five days preceding the next succeeding
distribution date, by so notifying the Trustee in writing, elect to terminate
his or her reinvestment plan and receive future distributions on his or her
Units in cash. There will be no charge or other penalty for such termination.
Each Reinvestment Fund, its sponsor and investment adviser shall have the
right to terminate at any time the reinvestment plan relating to such fund. 

Reports Provided. The Trustee shall furnish Unitholders in connection with
each distribution a statement of the amount of interest and, if any, the
amount of other receipts (received since the preceding distribution) being
distributed expressed in each case as a dollar amount representing the pro
rata share of each Unit outstanding. For as long as the Trustee deems it to be
in the best interests of the Unitholders, the accounts of the Trust shall be
audited, not less frequently than annually, by independent certified public
accountants and the report of such accountants shall be furnished by the
Trustee to Unitholders upon request. Within a reasonable period of time after
the end of each calendar year, the Trustee shall furnish to each person who at
any time during the calendar year was a registered Unitholder a statement (i)
as to the Interest Account: interest received (including amounts representing
interest received upon any disposition of Securities) and the percentage of
such interest by states in which the issuers of the Securities are located,
the amount of Purchased Interest, deductions for applicable taxes and for fees
and expenses of the Trust (including insurance costs), for redemptions of
Units, if any, and the balance remaining after such distributions and
deductions, expressed in each case both as a total dollar amount and as a
dollar amount representing the pro rata share of each Unit outstanding on the
last business day of such calendar year; (ii) as to the Principal Account: the
dates of disposition of any Securities and the net proceeds received therefrom
(excluding any portion representing accrued interest), the amount paid for
redemptions of Units, if any, deductions for payment of applicable taxes and
fees and expenses of the Trustee, the amount of "when issued"interest
treated as a return of capital, if any, and the balance remaining after such
distributions and deductions expressed both as a total dollar amount and as a
dollar amount representing the pro rata share of each Unit outstanding on the
last business day of such calendar year; (iii) a list of the Securities held
and the number of Units outstanding on the last business day of such calendar
year; (iv) the Redemption Price per Unit based upon the last computation
thereof made during such calendar year; and (v) amounts actually distributed
during such calendar year from the Interest and Principal Accounts, separately
stated, expressed both as total dollar amounts and as dollar amounts
representing the pro rata share of each Unit outstanding. 

In order to comply with Federal and state tax reporting requirements,
Unitholders will be furnished, upon request to the Trustee, evaluations of the
Securities in the Trust furnished to it by the Evaluator. 

Redemption of Units. A Unitholder may redeem all or a portion of his Units by
tender to the Trustee at its Unit Investment Trust Division, 101 Barclay
Street, 20th Floor, New York, New York 10286, of the certificates representing
the Units to be redeemed, duly endorsed or accompanied by proper instruments
of transfer with signature guaranteed (or by providing satisfactory indemnity,
as in connection with lost, stolen or destroyed certificates) and by payment
of applicable governmental charges, if any. Thus, redemption of Units cannot
be effected until certificates representing such Units have been delivered to
the person seeking redemption or satisfactory indemnity provided. No
redemption fee will be charged. On the seventh calendar day following such
tender, or if the seventh calendar day is not a business day, on the first
business day prior thereto, the Unitholder will be entitled to receive in cash
an amount for each Unit equal to the Redemption Price per Unit next computed
after receipt by the Trustee of such tender of Units. The "date of
tender"is deemed to be the date on which Units are received by the
Trustee, except that as regards Units received after 4:00 P.M. Eastern time on
days of trading on the New York Stock Exchange, the date of tender is the next
day on which such Exchange is open for trading and such Units will be deemed
to have been tendered to the Trustee on such day for redemption at the
redemption price computed on that day. 

Under regulations issued by the Internal Revenue Service, the Trustee will be
required to withhold a specified percentage of the principal amount of a Unit
redemption if the Trustee has not been furnished the redeeming Unitholder's
tax identification number in the manner required by such regulations. Any
amount so withheld is transmitted to the Internal Revenue Service and may be
recovered by the Unitholder only when filing a return. Under normal
circumstances the Trustee obtains the Unitholder's tax identification number
from the selling broker. However, at any time a Unitholder elects to tender
Units for redemption, such Unitholder should provide a tax identification
number to the Trustee in order to avoid this possible "back-up
withholding"in the event the Trustee has not been previously provided
such number. 

Purchased Interest, if applicable, and accrued interest paid on redemption
shall be withdrawn from the Interest Account of the Trust or, if the balance
therein is insufficient, from the Principal Account. All other amounts will be
withdrawn from the Principal Account. The Trustee is empowered to sell
underlying Securities in order to make funds available for redemption. Units
so redeemed shall be cancelled. 

The Redemption Price per Unit will be determined on the basis of the bid price
of the Securities in the Trust as of 4:00 P.M. Eastern time on days of trading
on the New York Stock Exchange on the date any such determination is made.
While the Trustee has the power to determine the Redemption Price per Unit
when Units are tendered for redemption, such authority has been delegated to
the Evaluator which determines the price per Unit on a daily basis. The
Redemption Price per Unit is the pro rata share of each Unit in the Trust
determined on the basis of (i) the cash on hand in the Trust or monies in the
process of being collected, (ii) the value of the Securities in the Trust
based on the bid prices of the Securities, except for those cases in which the
value of insurance has been included, (iii) Purchased Interest for each Trust
and (iv) interest accrued thereon, less (a) amounts representing taxes or
other governmental charges payable out of the Trust and (b) the accrued
expenses of the Trust. The Evaluator may determine the value of the Securities
in the Trust by employing any of the methods set forth in "Public Offering
Price". In determining the Redemption Price per Unit no value will be
assigned to the portfolio insurance maintained by the Trust on the Bonds in
the Trust unless such Bonds are in default in payment of principal or interest
or in significant risk of such default. On the other hand, Bonds insured under
a policy obtained by the issuer thereof are entitled to the benefits of such
insurance at all times and such benefits are reflected and included in the
market value of such Bonds. For a description of the situations in which the
Evaluator may value the insurance obtained by the Trust, see "Public
Offering Price". 

The price at which Units may be redeemed could be less than the price paid by
the Unitholder. As stated above, the Trustee may sell Securities to cover
redemptions. When Securities are sold, the size and diversity of the Trust
will be reduced. Such sales may be required at a time when Securities would
not otherwise be sold and might result in lower prices than might otherwise be
realized. 

The right of redemption may be suspended and payment postponed for any period
during which the New York Stock Exchange is closed, other than for customary
weekend and holiday closings, or during which the Securities and Exchange
Commission determines that trading on that Exchange is restricted or an
emergency exists, as a result of which disposal or evaluation of the
Securities in the Trust is not reasonably practicable, or for such other
periods as the Securities and Exchange Commission may by order permit. Under
certain extreme circumstances the Sponsor may apply to the Securities and
Exchange Commission for an order permitting a full or partial suspension of
the right of Unitholders to redeem their Units. 

TRUST ADMINISTRATION 

Sponsor Purchases of Units. The Trustee shall notify the Sponsor of any tender
of Units for redemption. If the Sponsor's bid in the secondary market at that
time equals or exceeds the Redemption Price per Unit, it may purchase such
Units by notifying the Trustee before the close of business on the second
succeeding business day and by making payment therefor to the Unitholder not
later than the day on which the Units would otherwise have been redeemed by
the Trustee. Units held by the Sponsor may be tendered to the Trustee for
redemption as any other Units. 

The offering price of any Units acquired by the Sponsor will be in accord with
the Public Offering Price described in the then currently effective prospectus
describing such Units. Any profit resulting from the resale of such Units will
belong to the Sponsor which likewise will bear any loss resulting from a lower
offering or redemption price subsequent to its acquisition of such Units. 

Portfolio Administration. The Trustee is empowered to sell, for the purpose of
redeeming Units tendered by any Unitholder, and for the payment of expenses
for which funds may not be available, such of the Bonds designated by the
Evaluator as the Trustee in its sole discretion may deem necessary. The
Evaluator, in designating such Bonds, will consider a variety of factors,
including (a) interest rates, (b) market value and (c) marketability. To the
extent that Bonds are sold which are current in payment of principal and
interest in order to meet redemption requests and defaulted Bonds are retained
in the portfolio in order to preserve the related insurance protection
applicable to said Bonds, the overall quality of the Bonds remaining in the
Trust's portfolio will tend to diminish. Except as described below and in
certain other unusual circumstances for which it is determined by the Trustee
to be in the best interests of the Unitholders or if there is no alternative,
the Trustee is not empowered to sell Bonds which are in default in payment of
principal or interest or in such significant risk of such default and for
which value has been attributed for the insurance obtained by the Trust.
Because of such restrictions on the Trustee under certain circumstances the
Sponsor may seek a full or partial suspension of the right of Unitholders to
redeem their Units. See "Rights of Unitholders  Redemption of Units".
The Sponsor is empowered, but not obligated, to direct the Trustee to dispose
of Bonds in the event of an advanced refunding. 

The Sponsor is required to instruct the Trustee to reject any offer made by an
issuer of any of the Bonds to issue new obligations in exchange or
substitution for any Bond pursuant to a refunding or refinancing plan, except
that the Sponsor may instruct the Trustee to accept or reject such an offer or
to take any other action with respect thereto as the Sponsor may deem proper
if (1) the issuer is in default with respect to such Bond or (2) in the
written opinion of the Sponsor the issuer will probably default with respect
to such Bond in the reasonably foreseeable future. Any obligation so received
in exchange or substitution will be held by the Trustee subject to the terms
and conditions of the Trust Agreement to the same extent as Bonds originally
deposited thereunder. Within five days after the deposit of obligations in
exchange or substitution for underlying Bonds, the Trustee is required to give
notice thereof to each Unitholder, identifying the Bonds eliminated and the
Bonds substituted therefor. Except as stated herein, the acquisition by the
Trust of any securities other than the Bonds initially deposited is not
permitted. 

If any default in the payment of principal or interest on any Bond occurs and
no provision for payment is made therefor either pursuant to the portfolio
insurance, or otherwise, within 30 days, the Trustee is required to notify the
Sponsor thereof. If the Sponsor fails to instruct the Trustee to sell or to
hold such Bond within 30 days after notification by the Trustee to the Sponsor
of such default, the Trustee may in its discretion sell the defaulted Bond and
not be liable for any depreciation or loss thereby incurred. 

Amendment or Termination. The Sponsor and the Trustee have the power to amend
the Trust Agreement without the consent of any of the Unitholders when such an
amendment is (a) to cure an ambiguity or to correct or supplement any
provision of the Trust Agreement which may be defective or inconsistent with
any other provision contained therein or (b) to make such other provisions as
shall not adversely affect the interest of the Unitholders (as determined in
good faith by the Sponsor and the Trustee), provided that the Trust Agreement
may not be amended to increase the number of Units issuable thereunder or to
permit the deposit or acquisition of securities either in addition to or in
substitution for any of the Securities initially deposited in the Trust,
except for the substitution of certain refunding securities for such Bonds. In
the event of any amendment, the Trustee is obligated to notify promptly all
Unitholders of the substance of such amendment. 

All Trusts other than those indicated in the next sentence may be terminated
at any time by consent of Unitholders representing 100% of the Units of the
Trust then outstanding. Each series of Insured Municipals Income Trust, Series
98 and subsequent series may be terminated at any time by consent of the
Unitholders representing 51% of the Units of such Trust then outstanding. In
addition, a Trust may be terminated by the Trustee when the value of the
Trust, as shown by any semi-annual evaluation, is less than that indicated
under "Summary of Essential Financial Information"in Part One of this
Prospectus. 

The Trust Agreement provides that the Trust shall terminate upon the
redemption, sale or other disposition of the last Security held in the Trust,
but in no event shall it continue beyond the end of the year indicated under
"The Trust". In the event of termination of the Trust, written notice
thereof will be sent by the Trustee to each Unitholder thereof at his address
appearing on the registration books of the Trust maintained by the Trustee.
Within a reasonable time thereafter the Trustee shall liquidate any Securities
then held in the Trust and shall deduct from the funds of the Trust any
accrued costs, expenses or indemnities provided by the Trust Agreement,
including estimated compensation of the Trustee and costs of liquidation and
any amounts required as a reserve to provide for payment of any applicable
taxes or other governmental charges. The sale of Securities in the Trust upon
termination may result in a lower amount than might otherwise be realized if
such sale were not required at such time. For this reason, among others, the
amount realized by a Unitholder upon termination may be less than the
principal amount of Securities represented by the Units held by such
Unitholder. The Trustee shall then distribute to each Unitholder his share of
the balance of the Interest and Principal Accounts. With such distribution the
Unitholders shall be furnished a final distribution statement of the amount
distributable. At such time as the Trustee in its sole discretion shall
determine that any amounts held in reserve are no longer necessary, it shall
make distribution thereof to Unitholders in the same manner. 

Notwithstanding the foregoing, in connection with final distributions to
Unitholders, it should be noted that because the portfolio insurance obtained
by the Trust is applicable only while Bonds so insured are held by the Trust,
the price to be received by the Trust upon the disposition of any such Bond
which is in default, by reason of nonpayment of principal or interest, will
not reflect any value based on such insurance. Therefore, in connection with
any liquidation, it shall not be necessary for the Trustee to, and the Trustee
does not currently intend to, dispose of any Bond or Bonds if retention of
such Bond or Bonds, until due, shall be deemed to be in the best interest of
Unitholders, including, but not limited to situations in which a Bond or Bonds
so insured are in default and situations in which a Bond or Bonds so insured
have a deteriorated market price resulting from a significant risk of default.
Since the Bonds which are insured by insurance obtained by the Bond issuer
will reflect the value of the related insurance, it is the present intention
of the Sponsor not to direct the Trustee to hold any of such Bonds after the
date of termination. All proceeds received, less applicable expenses, from
insurance on defaulted Bonds not disposed of at the date of termination will
ultimately be distributed to Unitholders of record as of such date of
termination as soon as practicable after the date such defaulted Bond or Bonds
become due and applicable insurance proceeds have been received by the
Trustee. 

Limitation on Liabilities. The Sponsor, the Evaluator and the Trustee shall be
under no liability to Unitholders for taking any action or for refraining from
taking any action in good faith pursuant to the Trust Agreement, or for errors
in judgment, but shall be liable only for their own willful misfeasance, bad
faith or negligence (gross negligence in the case of the Sponsor) in the
performance of their duties or by reason of their reckless disregard of their
obligations and duties hereunder. The Trustee shall not be liable for
depreciation or loss incurred by reason of the sale by the Trustee of any of
the Securities. In the event of the failure of the Sponsor to act under the
Trust Agreement, the Trustee may act thereunder and shall not be liable for
any action taken by it in good faith under the Trust Agreement. 

The Trustee shall not be liable for any taxes or other governmental charges
imposed upon or in respect of the Securities or upon the interest thereon or
upon it as Trustee under the Trust Agreement or upon or in respect of the
Trust which the Trustee maybe required to pay under any present or future law
of the United States of America or of any other taxing authority having
jurisdiction. In addition, the Trust Agreement contains other customary
provisions limiting the liability of the Trustee. 

The Trustee, Sponsor and Unitholders may rely on any evaluation furnished by
the Evaluator and shall have no responsibility for the accuracy thereof.
Determinations by the Evaluator under the Trust Agreement shall be made in
good faith upon the basis of the best of information available to it,
provided, however, that the Evaluator shall be under no liability to the
Trustee, Sponsor or Unitholders for errors in judgment. This provision shall
not protect the Evaluator in any case of willful misfeasance, bad faith, gross
negligence or reckless disregard to its obligations and duties. 

Sponsor. Van Kampen American Capital Distributors, Inc., a Delaware
corporation, is the Sponsor of the Trust. Van Kampen American Capital
Distributors, Inc. is primarily owned by Clayton, Dubilier & Rice, Inc., a New
York-based private investment firm. Van Kampen American Capital Distributors,
Inc. management owns a significant minority equity position. Effective
December 20, 1994, the parent of Van Kampen Merritt Inc. acquired American
Capital Management & Research, Inc. As a result, Van Kampen Merritt Inc., has
changed its name to Van Kampen American Capital Distributors, Inc. Van Kampen
American Capital Distributors, Inc. specializes in the underwriting and
distribution of unit investment trusts and mutual funds. The Sponsor is a
member of the National Association of Securities Dealers, Inc. and has offices
at One Parkview Plaza, Oakbrook Terrace, Illinois 60181, (708) 684-6000 and

branch office in Philadelphia and has regional representatives in Atlanta,
Dallas, Los Angeles, New York, San Francisco, Seattle and Tampa. As of
December 31, 1993 the total stockholders' equity of Van Kampen Merritt Inc.

not to the Insured Municipals Income Trust or to any Insured Multi-Series
thereof or to any other Underwriter. The information is included herein only
for the purpose of informing investors as to the financial responsibility of
the Sponsor and its ability to carry out its contractual obligations. More
detailed financial information will be made available by the Sponsor upon
request.)

As of September 30, 1994, and without giving effect to the merger, the Sponsor
and its affiliates managed or supervised approximately $35.4 billion of
investment products, of which over $23 billion is invested in municipal
securities. The Sponsor and its affiliates managed $22 billion of assets,
consisting of $7.7 billion for 20 open end mutual funds, $8.0 billion for 34
closed-end funds and $6.1 billion for 65 institutional accounts. The Sponsor
has also deposited approximately $24.5 billion of unit investment trusts.
Based on cumulative assets deposited, the Sponsor believes that it is the
largest sponsor of insured municipal unit investment trusts, primarily through
the success of its Insured Municipals Income Trust(R)or the IM-IT(R)
trust. The Sponsor also provides surveillance and evaluation services at cost
for approximately $13 billion of unit investment trust assets outstanding.
Since 1976, the Sponsor has serviced over one million retail investor
accounts, opened through retail distribution firms. Van Kampen American
Capital Distributors, Inc. is the sponsor of the various series of the trusts
listed below and the distributor of the mutual funds and closed-end funds
listed below. Unitholders may only invest in the trusts, mutual funds and
closed-end funds which are registered for sale in the state of residence of
such Unitholder. In order for a Unitholder to invest in the trusts, mutual
funds and closed-end funds listed below, such Unitholder must obtain a
prospectus relating to the trust or fund involved. A prospectus is the only
means by which an offer can be delivered to investors.

If the Sponsor shall fail to perform any of its duties under the Trust
Agreement or become incapable of acting or become bankrupt or its affairs are
taken over by public authorities, then the Trustee may (i) appoint a successor
Sponsor at rate of compensation deemed by the Trustee to be reasonable and not
exceeding amounts prescribed by the Securities and Exchange Commission, (ii)
terminate the Trust Agreement and liquidate the Trust as provided therein or
(iii) continue to act as Trustee without terminating the Trust Agreement.

Trustee. The Trustee is The Bank of New York, a trust company organized under
the laws of New York. The Bank of New York has its offices at 101 Barclay
Street, New York, New York 10286 (800) 221-7668. The Bank of New York is
subject to supervision and examination by the Superintendent of Banks of the
State of New York and the Board of Governors of the Federal Reserve System,
and its deposits are insured by the Federal Deposit Insurance Corporation to
the extent permitted by law. 

The duties of the Trustee are primarily ministerial in nature. It did not
participate in the selection of Securities for the Trust portfolio. 

In accordance with the Trust Agreement, the Trustee shall keep proper books of
record and account of all transactions at its office for the Trust. Such
records shall include the name and address of, and the certificates issued by
the Trust to, every Unitholder of the Trust. Such books and records shall be
open to inspection by any Unitholder at all reasonable times during the usual
business hours. The Trustee shall make such annual or other reports as may
from time to time be required under any applicable state or Federal statute,
rule or regulation (see "Unitholders Explanations - Public Offering -
Reports Provided"). The Trustee is required to keep a certified copy or
duplicate original of the Trust Agreement on file in its office available for
inspection at all reasonable times during the usual business hours by any
Unitholder, together with a current list of the Securities held in the Trust. 

Under the Trust Agreement, the Trustee or any successor trustee may resign and
be discharged of the Trust created by the Trust Agreement by executing an
instrument in writing and filing the same with the Sponsor. The Trustee or
successor trustee must mail a copy of the notice of resignation to all
Unitholders then of record, not less than 60 days before the date specified in
such notice when such resignation is to take effect. The Sponsor upon
receiving notice of such resignation is obligated to appoint a successor
trustee promptly. If, upon such resignation, no successor trustee has been
appointed and has accepted the appointment within 30 days after notification,
the retiring Trustee may apply to a court of competent jurisdiction for the
appointment of a successor. The Sponsor may remove the Trustee and appoint a
successor trustee as provided in the Trust Agreement at any time with or
without cause. Notice of such removal and appointment shall be mailed to each
Unitholder by the Sponsor. Upon execution of a written acceptance of such
appointment by such successor trustee, all the rights, powers, duties and
obligations of the original trustee shall vest in the successor. The
resignation or removal of a Trustee becomes effective only when the successor
trustee accepts its appointment as such or when a court of competent
jurisdiction appoints a successor trustee. 

Any corporation into which a Trustee may be merged or with which it may be
consolidated, or any corporation resulting from any merger or consolidation to
which a Trustee shall be a party, shall be the successor trustee. The Trustee
must be a banking corporation organized under the laws of the United States or
any state and having at all times an aggregate capital, surplus and undivided
profits of not less than $5,000,000.

Legal Opinions. The legality of the Units offered hereby has been passed upon
by Chapman and Cutler, 111 West Monroe Street, Chicago, Illinois 60603, as
counsel for the Sponsor. Various counsel have acted as counsel for the Trustee
and as special counsel for the Trust for New York tax matters.

related securities portfolio included in Part One of this Prospectus have been
audited by Grant Thornton LLP, independent certified public accountants, as

DESCRIPTION OF SECURITIES RATINGS* 

Standard & Poor's Ratings Group. A Standard & Poor's Ratings Group ("
Standard & Poor's") corporate or municipal bond rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
debt obligation. This assessment of creditworthiness may take into
consideration obligors such as guarantors, insurers or lessees. 

The bond rating is not a recommendation to purchase or sell a security,
inasmuch as it does not comment as to market price. 

The ratings are based on current information furnished to Standard & Poor's by
the issuer and obtained by Standard & Poor's from other sources it considers
reliable. The ratings may be changed, suspended or withdrawn as a result of
changes in, or unavailability of, such information. The ratings are based, in
varying degrees, on the following considerations: 

Likelihood of default capacity and willingness of the obligor as to the timely
payment of interest and repayment of principal in accordance with the terms of
the obligation. 

Nature of and provisions of the obligation. 

Protection afforded by, and relative position of, the obligation in the event
of bankruptcy, reorganization or other arrangements under the laws of
bankruptcy and other laws affecting creditors' rights. 

AAA  This is the highest rating assigned by Standard & Poor's to a debt
obligation and indicates an extremely strong capacity to pay principal and
interest. 

AA  Bonds rated AA also qualify as high-quality debt obligations. Capacity to
pay principal and interest is very strong, and in the majority of instances
they differ from AAA issues only in small degree. 

A  Bonds rated A have a strong capacity to pay principal and interest,
although they are somewhat more susceptible to the adverse effects of changes
in circumstances and economic conditions. 

BBB Bonds rated BBB are regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate
protection parameters, adverse economic conditions or changing circumstances
are more likely to lead to a weakened capacity to pay interest and repay
principal for debt in this category than in higher rated categories. 

*As published by the rating companies. 

Plus (+) or Minus (-): To provide more detailed indications of credit quality,
the ratings from "AA"to "BBB"may be modified by the addition
of a plus or minus sign to show relative standing within the major rating
categories. 

Provisional Ratings: A provisional rating "(p)"assumes the successful
completion of the project being financed by the issuance of the bonds being
rated and indicates that payment of debt service requirements is largely or
entirely dependent upon the successful and timely completion of the project.
This rating, however, while addressing credit quality subsequent to
completion, makes no comment on the likelihood of, or the risk of default upon
failure of, such completion. Accordingly, the investor should exercise his own
judgment with respect to such likelihood and risk. 

Moody's Investors Service, Inc. A brief description of the applicable Moody's
Investors Service, Inc. ("Moody's") rating symbols and their meanings
follows: 

Aaa  Bonds which are rated Aaa are judged to be the best quality. They carry
the smallest degree of investment risk and are generally referred to as "
gilt edge". Interest payments are protected by a large, or by an
exceptionally stable, margin and principal is secure. While the various
protective elements are likely to change, such changes as can be visualized
are most unlikely to impair the fundamentally strong position of such issues.
With the occasional exception of oversupply in a few specific instances, the
safety of obligations of this class is so absolute that their market value is
affected solely by money market fluctuation. 

Aa  Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known
as high grad e bonds. They are rated lower than the best bonds because margins
of protection may not be as large as in Aaa securities or fluctuations of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in Aaa
securities. These Aa bonds are high grade, their market value virtually immune
to all but money market influences, with the occasional exception of
oversupply in a few specific instances. 

A  Bonds which are rated A possess many favorable investment attributes and
are to be considered as higher medium grade obligations. Factors giving
security to principal and interest are considered adequate, but elements may
be present which suggest a susceptibility to impairment sometime in the
future. The market value of A rated bonds may be influenced to some degree by
credit circumstances during a sustained period of depressed business
conditions. During periods of normalcy, bonds of this quality frequently move
in parallel with Aaa and Aa obligations, with the occasional exception of
oversupply in a few specific instances. 

Baa Bonds which are rated Baa are considered as medium grade obligations;
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well. 

Moody's bond rating symbols may contain numerical modifiers of a generic
rating classification. The modifier 1 indicates that the bond ranks at the
high end of its category; the modifier 2 indicates a mid-range ranking; and
the modifier 3 indicates that the issue ranks in the lower end of its generic
rating category. 

Con  Bonds for which the security depends upon the completion of some act or
the fulfillment of some condition are rated conditionally. These are bonds
secured by (a) earnings of projects under construction, (b) earnings of
projects unseasoned in operating experience, (c) rentals which begin when
facilities are completed, or (d) payments to which some other limiting
condition attaches. Parenthetical rating denotes probable credit stature upon
completion of construction or elimination of basis of condition. 

No person is authorized to give any information or to make any representation
not contained in this Prospectus; and any information or representation not
contained herein must not be relied upon as having been authorized by the
Trust, the Sponsor or the dealers. This Prospectus does not constitute an
offer to sell, or a solicitation of an offer to buy, securities in any state
to any persons to whom it is not lawful to make such offer in such state.
