PROSPECTUS PART ONE 

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

Please retain both parts of this Prospectus for future reference. 

In the opinion of counsel, interest income to the 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 TRUST 

The above-named 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 of 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). 

The Units being offered by this Prospectus are issued and outstanding Units
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
resulting from the sale of Units will accrue to the Sponsor. No proceeds from
the sale of Units will be received by the Trust. 

PUBLIC OFFERING PRICE 

The Public Offering Price of the Units of each Trust is equal to the aggregate
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. 

ESTIMATED CURRENT AND LONG-TERM RETURNS 

Estimated Current and Long-Term Returns to Unitholders are indicated under
"Summary of Essential information"in this Part One. The methods of calculating
Estimated Current Returns and Estimated Long-Term Return are set forth in Part
Two of this Prospectus. 

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE A
CCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE. 

The Date of this Prospectus is August 15, 1994

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To The Board of Directors of Van Kampen Merritt Inc. and the Unitholders of
Insured Municipals Income Trust, Series 88: 

We have audited the accompanying statement of condition (including the
analysis of net assets) and the related portfolio of Insured Municipals Income
Trust, Series 88 as of April 30, 1994 and the related statements of operations
and changes in net assets for the three years ended April 30, 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 April 30,
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 88 as of April 30, 1994, and the results of operations and changes in
net assets for the three years ended April 30, 1994, in conformity with
generally accepted accounting principles.

INSURED MUNICIPALS INCOME TRUST 
SERIES 88
Notes to Financial Statements
April 30, 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 the Trust, (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 Trust maintains insurance which provides for the
timely payment when due, of all principal and interest on Bonds owned by it.
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 the Trust was based on the determination
by Interactive Data Services, Inc. of the offering prices of the Bonds on the
date of deposit (May 12, 1983). Since the valuation is based upon the bid
prices the Trust recognized a downward adjustment of $700,752 on the date of
deposit resulting from the difference between the bid and offering prices.
This downward adjustment was included in the aggregate amount of unrealized
depreciation reported in the financial statements for the period ended April
30, 1984. 

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

Federal Income Taxes - The Trust is not taxable for Federal income tax
purposes. Each Unitholder is considered to be the owner of a pro rata portion
of the Trust and, accordingly, no provision has been made for Federal income
taxes. 

Other - The financial statements are presented 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 Corporation. Ratings marked * are by Moody's Investors
Service, Inc. as these Bonds are not rated by Standard & Poor's Corporation.
N/R indicates that the Bond is not rated by Standard & Poor's Corporation 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
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 the 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 Trust has been obtained by the
Trust 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 Trust 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 April 30, 1994 is as follows: 



<TABLE>
<CAPTION>
<S>                      <C>       
Unrealized Appreciation  $ 632,716 
Unrealized Depreciation   (56,831) 
                         $ 575,885
</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 the 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 a fee for providing
portfolio supervisory services for the Trust ($.25 per Unit, not to exceed the
aggregate cost of the Evaluator for providing such services to all applicable
Trusts). In addition, the Evaluator receives an annual fee for regularly
evaluating the Trust's portfolio. Both fees may be adjusted for increases
under the category "All Services Less Rent of Shelter"in the Consumer Price
Index. 

NOTE 4-REDEMPTION OF UNITS 

During the years ended April 30, 1992, 1993 and 1994, 6 Units, 1 Unit and 1702
Units, respectively, were presented for redemption. 

NOTE 5-SUBSEQUENT EVENTS

Subsequent to April 30, 1994, New Jersey Economic Development Authority
Economic Development Revenue Bonds in the principal amounts of $25,000,
$135,000 and $735,000 were sold or redeemed at 102.785, 100 and 101,
respectively.






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 discount (plus earned

original issue discount) will constitute capital gains with respect to a

Unitholder who is not a dealer with respect to his Units. 



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 Corporation on the date the Trust was created.

Standard & Poor's Corporation 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 8. 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

EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES

AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE

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 Merritt



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 Merritt Inc., as Sponsor, American Portfolio

Evaluation Services, a division of Van Kampen Merritt 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 execute

on. 



The portfolio of the Discount Series may consist of bonds that were purchased

at a "market" discount from par value at maturity. A primary reason for the

market values of the Securities having been less than their par values is that

the coupon interest rates on the Securities at the time they were purchased

and deposited in the Discount Series were lower than the current market

interest rates for newly issued bonds of comparable rating and type. The

current yields (coupon interest income as a percentage of market price) of

discount bonds are lower than the current yields of comparably rated bonds of

similar type newly issued at current interest rates because discount bonds

tend to increase in market value as they approach maturity and the full

principal amount becomes payable. Under present law, a discount bond held to

maturity will have a larger portion of its total return in the form of capital

gain and less in the form of tax-exempt interest income than a comparable bond

newly issued at current market rates. See "Federal Tax Status." Discount bonds

with a longer term to maturity tend to have a higher current yield and a lower

current market value than otherwise comparable bonds with a shorter term to

maturity. If interest rates rise, the market discount of discount bonds will

increase and the value of the bonds will decrease; and if interest rates

decline, the market discount of discount bonds will decrease and the value of

the bonds will increase. Market discount attributable to interest rate changes

does not necessarily indicate a lack of market confidence in the issuer. 



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. 



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

Corporation 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 Corporation 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 Corporation 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 Merritt 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 Series 65 and subsequent 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 largest 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

I 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 and (f)

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".

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 may be obtained only from the applicable rating agency. 



The above ratings are not recommendations to buy, sell or hold the Bonds, and

such ratings may be subject to revision or withdrawal at any time by the

rating agencies. Any downward revision or withdrawal of either or both ratings

may have an adverse effect on the market price of the Bonds.

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 Corporation ("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 [SURETY BOND(S)] [IS] [ARE] NOT COVERED BY THE PROPERTY/CASUALTY INSURANCE

SECURITY FUND SPECIFIED IN ARTICLE 76 OF THE NEW YORK INSURANCE LAW. 



In connection with the Sale, Holdings and CapMAC entered into an Ownership

Policy Agreement (the "Ownership Policy Agreement"), which sets forth

Holdings' intent with respect to its ownership and control of CapMAC and

provides certain policies and agreements with respect to Holdings' exercise of

its control of CapMAC. In the Ownership Policy Agreement, Holdings has agreed

that, during the term of the Ownership Policy Agreement, it will not, and will

not permit any stockholder of Holdings to enter into any transaction the

result of which would be a change of control (as defined in the Ownership

Policy Agreement) of CapMAC, unless the long term debt obligations or

claims-paying ability of the person which would control CapMAC after such

transaction or its direct or indirect parent are rated in a high investment

grade category, unless Holdings or CapMAC has confirmed that CapMAC's

claims-paying ability rating by Moody's (the "Rating") in effect immediately

prior to any such change of control will not be downgraded by Moody's upon

such change of control or unless such change of control occurs as a result of

a public offering of Holdings' capital stock. 



In addition, the Ownership Policy Agreement includes agreements (i) not to

change the "zero-loss" underwriting standards or policies and procedures of

CapMAC in a manner that would materially and adversely affect the risk profile

of CapMAC's book of business, (ii) that CapMAC will adhere to the aggregate

leverage limitations and maintain capitalization levels considered by Moody's

from time to time as consistent with maintaining CapMAC's Rating and (iii)

that until CapMAC's statutory capital surplus and contingency reserve

("qualified statutory capital") equal$250 million, CapMAC will maintain a

specified amount of qualified statutory capital in excess of the amount of

qualified statutory capital that CapMAC is required at such time to maintain

under the aggregate leverage limitations set forth in Article 69 of the New

York Insurance Law. 



The Ownership Policy Agreement will terminate on the earlier of the date on

which a change of control of CapMAC occurs and the date on which CapMAC and

Holdings agree in writing to terminate the Ownership Policy Agreement;

provided that, CapMAC or Holdings has confirmed that CapMAC's Rating in effect

immediately prior to any such termination will not be downgraded upon such

termination. 



As at December 31, 1991 and 1990, CapMAC had statutory capital and surplus of

approximately $232 million and $223 million, respectively, and had not

incurred any debt obligations. On June 26, 1992, CapMAC made a special

distribution (the "Distribution") to Holdings in connection with the Sale in

an aggregate amount that caused the total of CapMAC's statutory capital and

surplus to decline to approximately $150 million. Holdings applied

substantially all of the proceeds of the Distribution to repay debt owed to

Citicorp that was incurred in connection with the capitalization of CapMAC. As

of June 30, 1992, CapMAC had statutory capital and surplus of approximately

$150 million and had not incurred any debt obligations. In addition, at June

30, 1992 CapMAC had a statutory contingency reserve of approximately $13

million, which is also available to cover claims under surety bonds issued by

CapMAC. Article 69 of the New York State Insurance Law requires that CapMAC

establishes and maintains the contingency reserve. 



In addition to its capital (including contingency reserve) and other

reinsurance available to pay claims under its surety bonds, on June 25, 1992,

CapMAC 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, having a term of 360 days. 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 Surety Bond(s). 



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 Corporation 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 Corporation 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 Corporation "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 Corporation) may or may not have a higher yield than

uninsured bonds rated "AAA" by Standard & Poor's Corporation. 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: 



the Trust is not an association taxable as a corporation for Federal income

tax purposes and interest and accrued original issue discount on Securities

which is excludable from gross income under the Internal Revenue Code of 1986

(the \xd2 Code\xd3 ) will retain its status, except to the extent such

interest is subject to the alternative minimum tax and the environmental tax

(the "Superfund Tax") as noted below, when distributed to Unitholders; 



each Unitholder is considered to be the owner of a pro rata portion of the

Trust under subpart E, subchapter J of chapter 1 of the Internal Revenue Code

of 1986 and will have a taxable event when the Trust disposes of a Security,

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

Trust, if any, on Securities delivered after the Unitholders pay for their

Units to the extent that such interest accrued on such Securities during the

period from the Unitholder's settlement date to the date such Securities are

delivered to the 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 said 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; 



any proceeds paid under an insurance policy issued to the Trust by one of the

Portfolio Insurers 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; and 



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 so excludable if paid in the normal course by the

issuer of the defaulted obligations. 



Sections 1288 and 1272 of the Internal Revenue Code of 1986 (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). 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, 1996 depend 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 minimum tax net operating loss deduction). "Adjusted

current earnings" includes all tax exempt interest, including interest on the

Bonds in the Trust. Corporate unitholders are urged to consult their tax

advisers with respect to the particular tax consequences to them resulting

from purchasing Units of the Trust, including the corporate alternative

minimum tax, the Superfund Tax and the branch profits tax imposed by Section

884 of the Co de. 



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

the 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 consider interest 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 Trust, the opinions of bond counsel

indicate that interest on such securities received by a "substantial user" of

the facilities being financed with the proceeds of these securities, or

persons related thereto, for periods while such securities are held by such a

user or related person, will not be exempt from Federal income taxes, although

interest on such securities received by others would be exempt from Federal

income taxes. "Substantial user" and "related person" are defined under U.S.

Treasury Regulations. Any person who believes he or she may be a substantial

user or related person as so defined should contact his or her tax adviser. 



At the time of closing, special counsel to the Trust for New York tax matters,

have rendered opinions substantially to the effect that the Trust is not an

association taxable as a corporation and the income of the Trust will be

treated as the income of the Unitholders under the then existing income tax

laws of the State and City of New York. 



All statements in the Prospectus concerning exclusion from gross income for

Federal, state or other taxes 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

Trust 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 34%, effective for long-term capital gains realized after

December 31, 1986. For taxpayers other than corporations, net capital gains

are subject to a maximum marginal stated tax rate of 28 percent. 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 Internal Revenue Code provides, in general, that fifty

percent of Social Security benefits are includible in gross income to the

extent that the sum of "modified adjusted gross income" plus fifty percent 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 includable 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

3'1,1993, 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,ooo 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 the Trust, will be subject to tax. A taxpayer whose

adjusted gross income already exceeds the base amount must include fifty

percent 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. 



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 also include

Purchased Interest. For purposes of 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: 



Years To Maturity Sales Charge      Years To Maturity       Sales Charge

1                       1.523%      9                             4.712%

2                        2.041      10                             4.932

3                        2.564      11                             4.932

4                        3.199      12                             4.932

5                        3.842      13                             5.374

6                        4.058      14                             5.374

7                        4.275      15                             5.374

8                        4.493      16 to 30                       6.045



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 Merritt 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 Merritt 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 Merritt Inc., a Delaware corporation, is the Sponsor of

the Trust. Van Kampen Merritt Inc. is primarily owned by Clayton, Dubilier &

Rice, Inc., a New York-based private investment firm. Van Kampen Merritt Inc.

management owns a significant minority equity position. Van Kampen Merritt

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 its principal office at One Parkview

Plaza, Oakbrook Terrace, Illinois 60181 (708) 684-6000. It maintains a branch

office in Philadelphia and has regional representatives in Atlanta, Dallas,

Los Angeles, New York, San Francisco, Seattle and Tampa. As of September 30,

1993, the total stockholders' equity of Van Kampen Merritt Inc. was

$200,885,000 (unaudited). (This paragraph relates only to the Sponsor and not

to the Trust. 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 November 30, 1993, the Sponsor and its affiliates managed, or supervised

approximately $38.5 billion of investment products, of which over $25 billion

is invested in municipal securities. The Sponsor managed $23 billion of

assets, consisting of $8.2 billion for 19 open end mutual funds, $8.3 billion

for 33 closed-end funds and $6.5 billion for 51 institutional accounts. The

Sponsor has also deposited over $23.5 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 Municipal Income Trust or the IM-IT trust. The Sponsor

also provides surveillance and evaluation services at cost for approximately

$15.5 billion of unit investment trust assets outstanding. Since 1976, the

Sponsor has opened over one million retail investor accounts through retail

distribution firms. Van Kampen Merritt 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. 



OTHER MATTERS 



Legal Opinions. The legality of the Units offered hereby has been passed upon

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. 



Independent Certified Public Accountants. The statement of condition and the

related securities portfolio included in Part One of this Prospectus have been

DESCRIPTION OF SECURITIES RATINGS* 



Standard & Poor's Corporation. A Standard & Poor's Corporation ("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: 



*As published by the rating companies. 



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. 



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.
