     The  attached  final Prospectus for a prior Series of  the  Fund  is
hereby used as a preliminary Prospectus for the above stated Series.  The
narrative information and structure of the attached final Prospectus will
be  substantially  the  same  as that of the final  Prospectus  for  this

and summary information regarding the characteristics of securities to be

securities in this Series are expected to be comparable to those  of  the
securities  deposited  in the previous Series.   However,  the  Estimated
Current  Return  for  this Series will depend on the interest  rates  and
offering  prices of the securities in this Series and may vary materially
from that of the previous Series.

be  filed  with the Securities and Exchange Commission but  has  not  yet
become  effective.  Information contained herein is subject to completion
or  amendment.   Such  Units may not be sold nor  may  offer  to  buy  be
accepted  prior to the time the registration statement becomes effective.
This Prospectus shall not constitute an offer to sell or the solicitation
of  an offer to buy nor shall there be any sale of the Units in any state
in  which  such  offer, solicitation or sale would be unlawful  prior  to
registration  or  qualification under the securities  laws  of  any  such

                   Van Kampen American Capital

Insured Municipals Income Trust, 198th Insured Multi-Series

IM-IT 371                Tennessee IM-IT 35
 

In the opinion of counsel, interest to the Fund and to Unitholders, with
certain exceptions, is excludable under existing law from gross income for
Federal income taxes. In addition, the interest income of each State Trust is,
in the opinion of counsel, exempt to the extent indicated from state and local
taxes, when held by residents of the state where the issuers of Bonds in such
Trust are located. Capital gains, if any, are subject to Federal tax.

 
The Fund. The objectives of the Fund are Federal and, in the case of a State
Trust, state tax-exempt income and conservation of capital through an
investment in a diversified portfolio of tax-exempt bonds. The Fund consists
of two underlying separate unit investment trusts designated as Insured
Municipals Income Trust, Series 371 (the "IM-IT") and Tennessee
Insured Municipals Income Trust, Series 35 (the "Tennessee IM-IT Trust"). 
The various trusts are collectively referred to herein as the 
"Trusts". The Tennessee IM-IT Trust is sometimes referred to herein as the
"State Trust", while the IM-IT and Tennessee IM-IT Trusts are
sometimes collectively referred to herein as the "Insured Trusts".
Each Trust initially consists of delivery statements relating to contracts to
purchase securities and, thereafter, will consist of such securities as may
continue to be held (the "Bonds" or "Securities"). Such
Securities are interest-bearing obligations issued by or on behalf of
municipalities and other governmental 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 the existing law. In
addition, the interest income of each State Trust is, in the opinion of
counsel, exempt to the extent indicated from state and local taxes, when held
by residents of the state where the issuers of Bonds in such Trust are located.

"AAA" Rating for the Insured Trusts. Insurance guaranteeing the
payments of principal and interest, when due, on the Securities in the
portfolio of each Insured Trust has been obtained from a municipal bond
insurance company either by such Trust or 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 an Insured Trust. See "Unitholder Explanations--Insurance on the
Bonds in the Insured Trusts" on page 21. Insurance obtained by an Insured
Trust applies only while Bonds are retained in such Trust while insurance
obtained on Preinsured Bonds is effective so long as such Bonds are
outstanding. The Trustee, upon the sale of a Bond insured under an insurance
policy obtained by an Insured 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 a
Trust and not to the Units offered hereby or to the market value thereof. As a
result of such insurance, the Units of each Insured Trust have received a
rating of "AAA" by Standard & Poor's, A Division of the McGraw-Hill
Companies. Standard & Poor's 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 each Insured Trust or sales by each Insured Trust
of Bonds for less than the purchase price paid by such Trust will reduce
payments to Unitholders of the interest and principal required to be paid on
such Bonds. See "Unitholder Explanations--Insurance on the Bonds in the
Insured Trusts". No representation is made as to any insurer's ability to
meet its commitments.

Public Offering Price. The Public Offering Price of the Units of each Trust
during the initial offering period includes the aggregate offering price of
the Securities in such Trust's portfolio, an applicable sales charge, cash, if
any, in the Principal Account held or owned by such Trust, and accrued
interest, if any. After the initial public offering period, the secondary
market Public Offering Price of each Trust will include the aggregate bid
price of the Securities in such Trust, an applicable sales charge, cash, if
any, in the Principal Account held or owned by such Trust, and accrued
interest, if any. If the Securities in each Trust were available for direct
purchase by investors, the purchase price of the Securities would not include
the sales charge included in the Public Offering Price of the Units. During
the initial offering period, the sales charge is reduced on a graduated scale
for sales involving at least 100 Units. If Units were available for purchase
at the close of business on the day before the Date of Deposit (except for the
IM-IT as of 8:00 A.M. Central Time on the Date of Deposit), the Public
Offering Price per Unit would have been that amount set forth in the "
Summary of Essential Financial Information" for each Trust. The minimum
purchase requirement is one Unit except for certain transactions described
under "Trust Administration--Unit Distribution". See "Unitholder
Explanations--Public Offering".
 

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.

 
Estimated Current Return and Estimated Long-Term Return. The annual Estimated
Current Returns and Estimated Long-Term Returns to Unitholders as of the close
of business on the day before the Date of Deposit (except for the IM-IT as of
8:00 A.M. Central Time on the Date of Deposit) under the monthly and
semi-annual distribution plans were as set forth under "Per Unit
Information" for each Trust. The methods of calculating Estimated Current
Return and Estimated Long-Term Return are set forth in the footnotes to the
"Per Unit Information" for each Trust.
 

Objectives of The Fund. The objectives of the Fund are income exempt from
Federal income tax and, in the case of a State Trust, Federal and state income
tax (if any) and conservation of capital through an investment in diversified
portfolios of Federal and state tax-exempt obligations. There is, of course,
no guarantee that the Fund will achieve its objectives. The Fund 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 Fund are often not available in small amounts. Units
of the Trust are not deposits or obligations of, or guaranteed or endorsed by,
any bank and are not federally insured or otherwise protected by the Federal
Deposit Insurance Corporation, the Federal Reserve Board or any other agency
and involve investment risk, including the possible loss of principal.

Distribution Options. Purchasers of Units who desire to receive distributions
on a monthly or semi-annual basis may elect to do so at the time of settlement
during the initial public offering period. See "Unitholder
Explanations--Settlement of Bonds in the Trusts--Change of Distribution
Option". The plan of distribution selected by such purchasers will remain
in effect until changed. Those indicating no choice will be deemed to have
chosen the monthly distribution plan. Record dates for monthly distributions
will be the tenth day of each month and record dates for semi-annual
distributions will be the tenth day of the months indicated under "Per
Unit Information" for the applicable Trust. Distributions will be made on
the twenty-fifth day of the month subsequent to the respective record dates.

Market for Units. Although not obligated to do so, the Sponsor, Van Kampen
American Capital Distributors, Inc., intends to, and certain of the other
Underwriters may, maintain a secondary market for the Units at prices based
upon the aggregate bid prices of the Securities in the respective Trusts plus
interest accrued to the date of settlement; however, during the initial
offering period such prices will be based upon the aggregate offering prices
of the Securities plus interest accrued to the date of settlement. If such a
market is not maintained and no other over-the-counter market is available, a
Unitholder will be able to dispose of his Units only through redemption at
prices based upon the bid prices of the underlying Securities plus interest
accrued to the date of settlement (see "Unitholder Explanations--Public
Offering--Redemption of Units" and "Unitholder Explanations--Public
Offering--Market for Units").

Reinvestment Option. Unitholders of any Van Kampen American Capital-sponsored
unit investment trust may utilize their redemption or termination proceeds to
purchase Units of any other Van Kampen American Capital trust in the initial
offering period accepting rollover investments subject to a reduced sales
charge to the extent stated in the related prospectus (which may be deferred
in certain cases).

Unitholders have the opportunity to have their distributions reinvested into
an open-end, management investment company as described herein. See 
"Unitholder Explanations--Public Offering--Reinvestment Option".

Risk Factors. An investment in the Trusts should be made with an understanding
of the risks associated therewith, including, among other factors, the
inability of the issuer or an insurer to pay the principal of or interest on a
bond when due, volatile interest rates, early call provisions, and changes to
the tax status of the Bonds. See "Unitholder Explanations--Settlement of
Bonds in the Trusts--Risk Factors".

<F2>Because certain of the Securities in certain Trusts may from time to time

<F3>Many unit investment trusts comprised of municipal securities issue a number
of units such that each unit represents approximately $1,000 principal amount
of underlying securities. The Sponsor, on the other hand, in determining the
number of Units for each Trust, other than IM-IT Limited Maturity, IM-IT
Intermediate and IM-IT Short Intermediate Trusts, has elected not to follow
this format but rather to provide that number of Units which will establish as
close as possible as of the Date of Deposit a Public Offering Price per Unit
of $1,000. For IM-IT Limited Maturity, IM-IT Intermediate and IM-IT Short
Intermediate Trusts, on the other hand, each unit represents $1,000 principal
amount of underlying securities in such Trust on the Date of Deposit.

<F4>Sales charges for the Trusts, expressed as a percentage of the Public Offering
Price per Unit and in parenthesis as a percentage of the aggregate offering
price of the Securities, are as follows: an IM-IT or a State Trust - 4.9%

Intermediate Trust - 3.9% (4.058%); or an IM-IT Short Intermediate Trust -
2.0% (2.041%).

<F5>Anyone ordering Units for settlement after the First Settlement Date will pay
accrued interest from such date to the date of settlement (normally three
business days after order) less distributions from the Interest Account
subsequent to the First Settlement Date. For purchases settling on the First
Settlement Date, no accrued interest will be added to the Public Offering
Price. After the initial offering period, the Sponsor's Repurchase Price per
Unit will be determined as described under the caption "Public

<F6>Such fee is based on the outstanding principal amount of Securities in each
Trust on the Date of Deposit for the first year and as of the close of

SETTLEMENT OF BONDS IN THE TRUSTS

 
The Fund. Insured Municipals Income Trust, 198th Insured Multi-Series (the
"Fund"), was created under the laws of the State of New York pursuant
to a Trust Indenture and Agreement (the "Trust Agreement"), dated the
Date of Deposit, among Van Kampen American Capital Distributors, Inc., as
Sponsor, American Portfolio Evaluation Services, a division of Van Kampen
American Capital Investment Advisory Corp., as Evaluator, and The Bank of New
York, as Trustee.

The Fund consists of two separate portfolios of delivery statements relating
to contracts to purchase 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. All issuers of Securities in a State
Trust are located in the State for which such Trust is named or in United
States territories or possessions and their public authorities; consequently,
in the opinion of recognized bond counsel to such State issuers, the related
interest earned on such Securities is exempt to the extent indicated from
state and local taxes of such State. With the exception of the New York and
Pennsylvania Trusts, Units of such Trusts may be purchased only by residents
of the State for which such Trust is named. Units of a New York Trust may be
purchased by residents of New York, Connecticut, Florida and Massachusetts.
Units of a Pennsylvania Trust may be purchased by residents of Pennsylvania,
Connecticut, Florida, Maryland, New York, Ohio and West Virginia. Offerees in
the States of Illinois, Indiana, Virginia and Washington may purchase Units of
the IM-IT Trust only. On the Date of Deposit, the Sponsor deposited with the
Trustee the aggregate principal amount of Securities in each Trust as
indicated under "General Information--Principal Amount (Par Value) of
Securities in Trust" in the "Summary of Essential Financial
Information". Such Securities consist of delivery statements relating to
contracts for the purchase of certain interest-bearing obligations and cash,
cash equivalents and/or irrevocable letters of credit issued by a financial
institution in the amount required for such purchases. Thereafter, the
Trustee, in exchange for the Securities so deposited, delivered to the Sponsor
the certificates evidencing the ownership of the number of Units in each Trust
as indicated under "Summary of Essential Financial Information." 
Unless otherwise terminated as provided herein, the Trust Agreement for any
IM-IT or State Trust will terminate at the end of the calendar year prior to
the fiftieth anniversary of its execution, and the Trust Agreement for any
IM-IT Limited Maturity Trust, IM-IT Intermediate Trust or IM-IT Short
Intermediate Trust will terminate at the end of the calendar year prior to the
twentieth anniversary of its execution.

The portfolio of any IM-IT or State Trust consists of Bonds maturing
approximately 15 to 40 years from the Date of Deposit. The approximate range
of maturities from the Date of Deposit for Bonds in any IM-IT Limited Maturity
Trust, IM-IT Intermediate Trust and IM-IT Short Intermediate Trust is 12 to 15
years, 5 to 15 years and 3 to 7 years, respectively. The dollar-weighted
average maturity of the Bonds in any IM-IT Intermediate Trust and IM-IT Short
Intermediate Trust is less than or equal to 10 years and 5 years, respectively.
 

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

Certain of the Bonds in certain of the Trusts may be "zero coupon" 
bonds. See footnote (6) in "Notes to Portfolios". 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.

Certain of the Bonds in certain of the Trusts may have been purchased on a
"when, as and if issued" or "delayed delivery" basis. See
footnote (5) in "Notes to Portfolios". The delivery of any such
Securities may be delayed or may not occur. Interest on these Securities
begins accruing to the benefit of Unitholders on their respective dates of
delivery. To the extent any Securities are actually delivered to the Fund
after their respective expected dates of delivery, Unitholders who purchase
their Units prior to the date such Securities are actually delivered to the
Trustee would be required to adjust their tax basis in their Units for a
portion of the interest accruing on such Securities during the interval
between their purchase of Units and the actual delivery of such Securities. As
a result of any such adjustment, the Estimated Current Returns during the
first year would be slightly lower than those stated herein which would be the
returns after the first year, assuming the portfolio of a Trust and estimated
annual expenses other than that of the Trustee (which may be reduced in the
first year only) do not vary from that set forth under "Per Unit
Information" for the applicable Trust. Holders of the Units will be 
"at risk" with respect to all Securities in the portfolios including 
"when, as and if issued" and "delayed delivery" Securities (i.e.,
may derive either gain or loss from fluctuations in the evaluation of such
Securities) from the date they commit for Units. For a discussion of the
Sponsor's obligations in the event of the failure of any contract for the
purchase of any of the Securities and limited right to substitute other
tax-exempt bonds to replace any failed contract, see "Replacement
Bonds" below.

Each Unit initially offered represents the fractional undivided interest in
the principal and net income of a Trust indicated under "Summary of
Essential Financial Information". To the extent that any Units are
redeemed by the Trustee, the fractional undivided interest in a Trust
represented by each unredeemed Unit will increase, although the actual
interest in such 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 Fund are income
exempt from Federal income taxation and, in the case of a State Trust, Federal
and state income taxation and conservation of capital through an investment in
diversified portfolios of Federal and state tax-exempt obligations. There is,
of course, no guarantee that the Trusts will achieve their respective
objectives. The Fund 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 Fund are often not
available in small amounts.

Insurance guaranteeing the timely payment, when due, of all principal and
interest on the Bonds in each Insured Trust has been obtained by such Trust
from either AMBAC Indemnity Corporation ("AMBAC Indemnity"), Financial
Guaranty Insurance Company ("Financial Guaranty" or "FGIC") 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 such 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) MBIA Insurance Corporation ("MBIA"), (4) Bond
Investors Guaranty Insurance Company ("BIG"), (5) National Union Fire
Insurance Company of Pittsburgh, PA. ("National Union"), (6) Capital
Guaranty Insurance Company ("Capital Guaranty"), (7) Capital Markets
Assurance Corporation ("CapMAC") and/or (8) Financial Security
Assurance Inc. ("Financial Security" or "FSA") (collectively,
the "Preinsured Bond Insurers") (see "Unitholder
Explanations--Insurance on the Bonds in the Insured Trusts"). Insurance
obtained by an Insured Trust is effective only while the Bonds thus insured
are held in such 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 of such Bonds or by the Sponsor from one of the Preinsured Bond Insurers
(the "Preinsured Bonds") are not additionally insured by an Insured
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 an Insured Trust, if any, unless Bonds are in default in payment
of principal or interest or in significant risk of such default. See "
Unitholder Explanations--Public Offering--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
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 "Other Matters--Description of
Securities 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 Portfolio
Insurer by an Insured Trust upon the payment of a single predetermined
insurance premium from the proceeds of the sale of such Bond. Accordingly, any
Bond in an Insured Trust is eligible to be sold on an insured basis. All Bonds
insured by the Portfolio Insurers and the Preinsured Bond Insurers receive a
"AAA" rating by Standard & Poor's. See "Unitholder
Explanations--Insurance on the Bonds in the Insured Trusts".

In selecting Securities for the Trusts the following facts, among others, were
considered by the Sponsor: (a) either the Standard & Poor's rating of the
Securities was in no case less than "BBB-" in the case of the Insured
Trusts, or the Moody's Investors Service, Inc. rating of the Securities was in
no case less than "Baa" in the case of the Insured Trusts, including
provisional or conditional ratings, respectively, or, if not rated, the
Securities had, in the opinion of the Sponsor, credit characteristics
sufficiently similar to the credit characteristics of interest-bearing
tax-exempt obligations that were so rated as to be acceptable for acquisition
by the Fund (see "Other Matters--Description of Securities Ratings"),
(b) the prices of the Securities relative to other bonds of comparable quality
and maturity, (c) the diversification of Securities as to purpose of issue and
location of issuer and (d) with respect to the Insured Trusts, the
availability and cost of insurance for the prompt payment of principal and
interest, when due, on the Securities. Subsequent to the Date of Deposit, a
Security 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
Security from the portfolio of a Trust but may be considered in the Sponsor's
determination as to whether or not to direct the Trustee to dispose of the
Security (see "Trust Administration--Fund Administration and
Expenses--Portfolio Administration").

To the best knowledge of the Sponsor, there is 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.

Risk Factors. Certain of the Bonds in certain of the Trusts 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 such a 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 Trusts 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 certain of the Trusts may be obligations which derive
their payments 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 such a
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 Fund, the Sponsor at the Date of Deposit is not aware that any of
the respective issuers of such Bonds are actively considering the redemption
of such Bonds prior to their respective stated initial call dates. See "
General" for each Trust.

Certain of the Bonds in certain of the Trusts may be health care revenue
bonds. In view of this an investment in such a 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 service may 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 Securities held in
the portfolios of the Fund; however, because of the insurance obtained by each
of the Insured Trusts, the "AAA" rating of the Units of each of the
Insured Trusts would not be affected. See "General" for each Trust.

Certain of the Bonds in certain of the Trusts may be obligations of public
utility issuers, including those selling wholesale and retail electric power
and gas. In view of this an investment in such a 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. See "General" for
each Trust.

Certain of the Bonds in certain of the Trusts 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 such a 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. See 
"General" for each Trust.

Certain of the Bonds in certain of the Trusts may be industrial revenue bonds
("IRBs"). In view of this an investment in such a 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. See "General" for each Trust.

Certain of the Bonds in certain of the Trusts 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 such a 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 is
ordinarily backed by the municipality's covenant to appropriate for 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. See "General" for each Trust.

Certain of the Bonds in certain of the Trusts 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 such a 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 Trusts. 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.
See "General" for each Trust.

Certain of the Bonds in certain of the Trusts 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 such a 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. See
"General" for each Trust.

Certain of the Bonds in certain of the Trusts 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 such a 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. See "General" for each Trust.

Replacement Bonds. Because certain of the Securities in the Fund 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 any 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 Security. In the event of a failure
to deliver any Security that has been purchased for the Fund under a contract,
including those Securities purchased on a "when, as and if issued" 
basis ("Failed Bonds"), the Sponsor is authorized under the Trust
Agreement to direct the Trustee to acquire other bonds ("Replacement
Bonds") to make up the original corpus of the Fund.

 
The Replacement Bonds must be purchased within 20 days after delivery of the
notice of the failed contract and the purchase price (exclusive of accrued
interest) may not exceed the amount of funds reserved for the purchase of the
Failed Bonds. The Replacement Bonds (i) must be tax-exempt bonds issued by
states or territories of the United States or political subdivisions thereof
and, in the case of replacement of bonds in a State Trust, shall have the
benefit of an exemption from state taxation of interest to an extent equal to
or greater than that of the bonds they replace, (ii) must have a fixed
maturity date of at least 10 years in the case of an IM-IT or a State Trust
or, in the case of an IM-IT Limited Maturity, IM-IT Intermediate or IM-IT
Short Intermediate Trust, must have a fixed maturity date within the range set
forth under "Unitholder Explanations--Settlement of Bonds in the
Trusts--The Fund", (iii) must be purchased at a price that results in a
yield to maturity and in a current return, in each case as of the Date of
Deposit, at least equal to that of the Failed Bonds, (iv) shall not be "
when, as and if issued" bonds, (v) must be rated "BBB-" or better
in the case of the Insured Trusts by Standard & Poor's or "Baa" or
better in the case of the Insured Trusts by Moody's Investors Service, Inc.
and (vi) with respect to each Insured Trust, must be insured by one of the
Preinsured Bond Insurers or be eligible for (and when acquired be insured
under) the insurance obtained by such Insured Trust. Whenever a Replacement
Bond has been acquired for the Fund, the Trustee shall, within five days
thereafter, notify all Unitholders of the affected Trust of the acquisition of
the Replacement Bond and shall, on the next monthly distribution date which is
more than 30 days thereafter, make a pro rata distribution of the amount, if
any, by which the cost to the affected Trust of the Failed Bond exceeded the
cost of the Replacement Bond plus accrued interest. Once the original corpus
of a Trust is acquired, the Trustee will have no power to vary the investment
of the Trust; i.e., the Trust will have no managerial power to take advantage
of market variation to improve a Unitholder's investment.
 

If the right of limited substitution described in the preceding paragraph
shall not be utilized to acquire Replacement Bonds in the event of a failed
contract, the Sponsor will refund the sales charge attributable to such Failed
Bonds to all Unitholders of the affected Trust and distribute the principal
and accrued interest (at the coupon rate of such Failed Bonds to the date the
Failed Bonds are removed from the Fund) attributable to such Failed Bonds not
more than 30 days after such removal or such earlier time as the Trustee in
its sole discretion deems to be in the interest of the Unitholders. All such
interest paid to a Unitholder which accrued after the expected date of
settlement for purchase of his Units will be paid by the Sponsor and
accordingly will not be treated as tax-exempt income. In the event a
Replacement Bond should not be acquired by the Fund, the Estimated Net Annual
Interest Income per Unit for the affected Trust would be reduced and the
Estimated Current Return and Estimated Long-Term Return thereon might be
lowered. In addition, Unitholders should be aware that they may not be able at
the time of receipt of such principal to reinvest such proceeds in other
securities at a yield equal to or in excess of the yield which such proceeds
were earning to Unitholders in the affected Trust.

Bond Redemptions. Certain of the Bonds in certain of the Trusts 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; it may also affect the current return on Units of the
Trust involved. Each Trust 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 "Portfolio" for each Trust and footnote (3)
in the "Notes to Portfolios". See also the discussion of single family
mortgage and multi-family revenue bonds above for more information on the call
provisions of such bonds.

Distributions. Distributions of interest received by the Fund, pro rated on an
annual basis, will be made on a monthly basis, unless the Unitholder elects to
receive them semi-annually. The first such distribution will be in the amount
indicated under "Per Unit Information" for the applicable Trust and
will be made on the twenty-fifth day of the month indicated under "Initial
Distribution" therein to Unitholders of record on the tenth day of such
month. The first distribution of funds from the Principal Account, if any,
will be made on the first semi-annual distribution date to Unitholders of
record on the first semi-annual record date, and thereafter such distributions
will be made on a semi-annual basis, except under certain special
circumstances (see "Unitholder Explanations--Public
Offering--Distributions of Interest and Principal").

Change of Distribution Option. The plan of distribution selected by a
Unitholder 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 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 only be sent 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 as of the opening of business on the first day after the next
succeeding semi-annual record date and will be effective, unless further
changed, for all subsequent distributions.

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 each Trust is evidenced by separate registered
certificates executed by the Trustee and the Sponsor unless a Unitholder makes
a request to the Trustee that Units be held in book-entry form. 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 (or on such request) 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. Certificates will be
issued in denominations of one Unit or any multiple thereof. Certificates for
Units will bear appropriate notations on their face indicating which plan of
distribution has been selected in respect thereof. If a change in the plan of
distribution is made, the existing certificate must be surrendered to the
Trustee and a new certificate will be issued, at no charge to the Unitholder,
to reflect the currently effective plan of distribution.

Although no such charge is now made or contemplated, the Trustee may require a
Unitholder to pay a reasonable fee for each certificate re-issued (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.

ESTIMATED CURRENT RETURNS AND ESTIMATED LONG-TERM RETURNS

 
As of the close of business on the day before the Date of Deposit (except for
the IM-IT as of 8:00 A.M. Central Time on the Date of Deposit) the Estimated
Current Returns and the Estimated Long-Term Returns, under the monthly and
semi-annual distribution plans, were as set forth in the "Per Unit
Information" for each Trust. Estimated Current Return is 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; therefore, there is no assurance that the
present Estimated Current Return will be realized in the future. Estimated
Long-Term Return is 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 a 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 a Trust will change, there
is no assurance that the present Estimated Long-Term Return will be realized
in the future. The Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of Estimated Long-Term Return
reflects the estimated date and amount of principal returned while the
Estimated Current Return calculation includes only net annual interest income
and Public Offering Price.
 

In order to acquire certain of the Securities contracted for by the Sponsor
for deposit in the Fund, it may be necessary for the Sponsor or Trustee to pay
on the settlement dates for delivery of such Securities amounts covering
accrued interest on such Securities which exceed the amounts which will be
made available through cash furnished by the Sponsor on the Date of Deposit,
which amount of cash may exceed the interest which would accrue to the First
Settlement Date. The Trustee has agreed to pay for any amounts necessary to
cover any such excess and will be reimbursed therefor, when funds become
available from interest payments on the particular Securities with respect to
which such payments may have been made. Also, since interest on any "when,
as and if issued" Securities does not begin accruing as tax-exempt
interest income to the benefit of Unitholders until their respective dates of
delivery, the Trustee may, in order to maintain (or in some cases approach)
for the Unitholders the same estimated net annual interest incomes during the
first year of the Trusts' operations as is indicated under "Per Unit
Information" for the applicable Trust, reduce its fee (and to the extent
necessary pay Trust expenses) in an amount equal to that indicated under 
"Per Unit Information" for the applicable Trust.

INTEREST EARNING SCHEDULE

Calculation of Estimated Net Annual Interest Income. The estimated net annual
interest income is based on 360 days. To account for the estimated net annual
interest income per Unit in a Trust, it is necessary to use the following
information.

 
The beginning interest date for each Trust is May 7, 1996. The first monthly
record date for each Trust (June 10, 1996) is 33 days from such date. The
daily rates of estimated net annual interest income per Unit accrued on a
monthly basis are $.15190 and $.14449 for the IM-IT and Tennessee IM-IT
Trusts, respectively. This amounts to $5.01 and $4.77 for the IM-IT and
Tennessee IM-IT Trusts, respectively.

Utilizing the preceding information assuming the monthly payment option, the
following procedure illustrates the calculation of first year estimated net
annual interest income per Unit for the Tennessee IM-IT Trust:

The Tennessee IM-IT Trust accrues

$4.77 to the first record date plus

$43.40 which is 10 normal distributions at $4.34, and finally adding 

$3.85 which has accrued from April 10, 1997 until May 7, 1997 which completes
the 360 day cycle (27 days times the daily factor)

Total $52.02 interest earned /$1,000.00 (Date of Deposit Public Offering
Price) = 5.20% Estimated Current Return as of the Date of Deposit.
 

ACCRUED INTEREST

Accrued Interest. Accrued interest is an accumulation of unpaid interest on
securities which generally is paid semi-annually, although the Trust accrues
such interest daily. Because of this, the Trust always has an amount of
interest earned but not yet collected by the Trustee. For this reason, with
respect to sales settling subsequent to the First Settlement Date, 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 the Trust the amount, if any, of accrued interest
paid on their Units.

In an effort to reduce the amount of accrued interest which would otherwise
have to be paid by Unitholders, the Trustee will advance the amount of 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, less any distributions from the
Interest Account subsequent to the First Settlement Date. See "Public
Offering--Distributions 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 accrued interest from the purchaser of his
Units. Since the Trustee has the use of the funds held in the Interest Account
for distributions to Unitholders and since such Account is
non-interest-bearing to Unitholders, the Trustee benefits thereby.

PUBLIC OFFERING

 
General. Units are offered at the Public Offering Price. During the initial
offering period the Public Offering Price is based on the aggregate offering
price of the Securities in such Trust's portfolio, a sales charge of 4.9% of
the Public Offering Price (5.152% of the aggregate offering price of the
Securities) for an IM-IT or a State Trust, 4.3% of the Public Offering Price
(4.493% of the aggregate offering price of the Securities) for an IM-IT
Limited Maturity Trust, 3.9% of the Public Offering Price (4.058% of the
aggregate offering price of the Securities) for an IM-IT Intermediate Trust
and 2.0% of the Public Offering Price (2.041% of the aggregate offering price
of the Securities) for an IM-IT Short Intermediate Trust, cash, if any, in the
Principal Account held or owned by such Trust, and accrued interest, if any.
After the initial public offering period, the secondary market public offering
price is based on the bid prices of the Securities in each Trust, an
applicable sales charge as determined in accordance with the table set forth
below, which is based upon the dollar weighted average maturity of each Trust,
cash, if any, in the Principal Account held or owned by such Trust, and
accrued interest, if any. 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 are subject to redemption 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 estimated
long-term return life of such Trust's Portfolio, in accordance with the
following schedule:

The sales charges in the above table are expressed as a percentage of the
aggregate bid prices of the Securities in a Trust. Expressed as a percent of
the Public Offering Price, the sales charge on a Trust consisting entirely of
a portfolio of Bonds with 15 years to maturity would be 4.8%. The sales charge
applicable to quantity purchases during the initial offering period is,
however, reduced on a graduated basis to any person acquiring 100 or more
Units as follows:

Any such reduced sales charge shall be the responsibility of the selling
Underwriter, broker, dealer or agent. The Sponsor will, however, increase the
concession or agency commission for such quantity purchases. See "Public
Offering--Unit Distribution". This reduced sales charge structure will
apply on all purchases by the same person from any one Underwriter or dealer
of units of Van Kampen American Capital-sponsored unit investment trusts which
are being offered in the initial offering period (a) on any one day (the 
"Initial Purchase Date") or (b) on any day subsequent to the Initial
Purchase Date, if (1) the units purchased are of a unit investment trust
purchased on the Initial Purchase Date, and (2) the person purchasing the
units purchased a sufficient amount of units on the Initial Purchase Date to
qualify for a reduced sales charge on such date. In the event units of more
than one trust are purchased on the Initial Purchase Date, the aggregate
dollar amount of such purchases will be used to determine whether purchasers
are eligible for a reduced sales charge. Such aggregate dollar amount will be
divided by the public offering price per unit (on the day preceding the date
of purchase) of each respective trust purchased to determine the total number
of units which such amount could have purchased of each individual trust.
Purchasers must then consult the applicable trust's prospectus to determine
whether the total number of units which could have been purchased of a
specific trust would have qualified for a reduced sales charge and, if so
qualified, the amount of such reduction. Assuming a purchaser qualifies for a
sales charge reduction or reductions, to determine the applicable sales charge
reduction or reductions it is necessary to accumulate all purchases made on
the Initial Purchase Date and all purchases made in accordance with (b) above.
Units purchased in the name of the spouse of a purchaser or in the name of a
child of such purchaser under 21 years of age will be deemed for the purposes
of calculating the applicable sales charge to be additional purchases by the
purchaser. The reduced sales charges will also be applicable to a trustee or
other fiduciary purchasing securities for one or more trust estate or
fiduciary accounts. Employees of Van Kampen American Capital Distributors Inc.
and its subsidiaries may purchase Units of the Trust at the current Public
Offering Price less the underwriting commission or less the dealer's
concession in the absence of an underwriting commission. Registered
representatives of selling Underwriters may purchase Units of the Fund at the
current Public Offering Price less the underwriting commission during the
initial offering period, and less the dealer's concession for secondary market
transactions. Registered representatives of selling brokers, dealers, or
agents may purchase Units of the Fund at the current Public Offering Price
less the dealer's concession during the initial offering period and for
secondary market transactions.

Units may be purchased in the primary or secondary market at the Public
Offering Price (for purchases which do not qualify for a sales charge
reduction for quantity purchases) less the concession the Sponsor typically
allows to brokers and dealers for purchases (see "Trust
Administration--General--Unit Distribution") by (1) investors who purchase
Units through registered investment advisers, certified financial planners and
registered broker-dealers who in each case either charge periodic fees for
financial planning, investment advisory or asset management services, or
provide such services in connection with the establishment of an investment
account for which a comprehensive "wrap fee" charge is imposed, (2)
bank trust departments investing funds over which they exercise exclusive
discretionary investment authority and that are held in a fiduciary, agency,
custodial or similar capacity, (3) any person who for at least 90 days, has
been an officer, director or bona fide employee of any firm offering Units for
sale to investors or their immediate family members (as described above) and
(4) officers and directors of bank holding companies that make Units available
directly or through subsidiaries or bank affiliates. Notwithstanding anything
to the contrary in this Prospectus, such investors, bank trust departments,
firm employees and bank holding company officers and directors who purchase
Units through this program will not receive sales charge reductions for
quantity purchases.

Offering Price. Public Offering Price of the Units will vary from the amounts
stated under "Summary of Essential Financial Information" in
accordance with fluctuations in the prices of the underlying Securities in
each Trust.

 
As indicated above, the price of the Units as of the date the Securities were
deposited in each Trust was determined by adding to the aggregate offering
price of the Securities of a Trust an amount equal to the applicable sales
charge expressed as a percentage of the aggregate offering price of the
Securities and dividing the sum so obtained by the number of Units
outstanding. This computation produced a gross underwriting commission equal
to such sales charge expressed as a percentage of the Public Offering Price.
Such price determination as of the close of business on the day before the
Date of Deposit (except for the IM-IT as of 8:00 A.M. Central Time on the Date
of Deposit) was made on the basis of an evaluation of the Securities in each
Trust prepared by Interactive Data Corporation, a firm regularly engaged in
the business of evaluating, quoting or appraising comparable securities. After
the close of business on the day before the Date of Deposit (except for the
IM-IT as of 8:00 A.M. Central Time on the Date of Deposit) and during the
period of initial offering, the Evaluator will appraise or cause to be
appraised daily the value of the underlying Securities of each Trust as of
4:00 P.M. Eastern time on days the New York Stock Exchange is open for
business and will adjust the Public Offering Price of the Units commensurate
with such appraisal. Such Public Offering Price will be effective for all
orders received at or prior to 4:00 P.M. Eastern time on each such day. Orders
received by the Trustee, Sponsor or any Underwriter for purchases, sales or
redemptions after that time, or on a day when the New York Stock Exchange is
closed, will be held until the next determination of price. For secondary
market sales the Public Offering Price per Unit will be equal to the aggregate
bid price of the Securities in the Trust plus an amount equal to the
applicable secondary market sales charge expressed as a percentage of the
aggregate bid price of the Securities and dividing the sum so attained by the
number of Units then outstanding. This computation produces a gross commission
equal to such sales charge expressed as a percentage of the Public Offering
Price. For secondary market purposes such appraisal and adjustment with
respect to a Trust will be made by the Evaluator as of 4:00 P.M. Eastern time
on days in which the New York Stock Exchange is open for each day on which any
Unit of such Trust is tendered for redemption, and it shall determine the
aggregate value of any Trust as of 4:00 P.M. Eastern time on such other days
as may be necessary.
 

The aggregate price of the Securities in each Trust has been and will be
determined on the basis of bid prices or offering prices, as is appropriate,
(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 Fund; (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 an Insured Trust, if
any.

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 an Insured
Trust and reflects a proper valuation method in accordance with the provisions
of the Investment Company Act of 1940.

No value has been ascribed to insurance obtained by an Insured Trust, if any,
as of the date of this Prospectus.

The initial or primary Public Offering Price of the Units is equal to the
offering price per Unit of the underlying Securities in each Trust plus the
applicable sales charge plus interest accrued but unpaid from the First
Settlement Date to the date of settlement. The secondary market Public
Offering Price is equal to the bid price per Unit of the Securities in each
Trust plus the applicable sales charge plus accrued interest. The offering
price of Securities in each Trust may be expected to average approximately
0.5%-1% more than the bid price of such Securities. On the Date of Deposit,
the offering side evaluations of the Securities in the Trusts were higher than
the bid side evaluations of such Securities by the respective amounts
indicated under footnote (5) in "Notes to Portfolios".

Although payment is normally made three business days following the order for
purchase, payment may be made prior thereto. 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. Delivery of certificates representing Units so ordered
will be made three business days following such order or shortly thereafter.
See "Redemption of Units" below for information regarding the ability
to redeem Units ordered for purchase.

Market for Units. During the initial public offering period, the Sponsor
and/or certain of the Underwriters intend to offer to purchase Units at a
price equivalent to the Public Offering Price which is based upon the
aggregate offering price per Unit of the underlying Securities in each Trust
plus accrued interest to the date of settlement less the related sales
commission. Afterward, although they are not obligated to do so, the Sponsor
intends to, and certain of the other Underwriters 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 each Trust plus interest accrued to the
date of settlement and 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 Underwriters
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 of any
Trust 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 any accrued interest. The aggregate bid prices of the
underlying Securities in a Trust are expected to be less than the related
aggregate offering prices. See "Redemption of Units" below. 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.

Distributions of Interest and Principal. Interest received by the Fund,
including that part of the proceeds of any disposition of Securities which
represents accrued interest, is credited by the Trustee to the Interest
Account for the appropriate Trust. Other receipts are credited to the
Principal Account for the appropriate Trust. Interest received by the Fund
after deduction of amounts sufficient to reimburse the Trustee, without
interest, for any amounts advanced and paid to the Sponsor as the Unitholder
of record as of the First Settlement Date (see "Public Offering--Offering
Price" above) will be distributed on or shortly after the twenty-fifth day
of each month on a pro rata basis to Unitholders of record of a Trust as of
the preceding record date who are entitled to distributions at that time under
the plan of distributions chosen. All distributions will be net of applicable
expenses. The pro rata share of cash in the Principal Account of a Trust will
be computed as of the date set forth under "Per Unit Information" for
the applicable Trust, and thereafter 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 twenty-fifth day of such month. 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 any Principal or Interest Account (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.
However, should the amount available for distribution in the Principal Account
equal or 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 distribution to the Unitholders of a Trust as of each record date after
the First Settlement 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 Unitholder's pro rata share of the estimated net annual
interest income in the Interest Account of such Trust after deducting
estimated expenses attributable as is consistent with the distribution plan
chosen. Because interest payments are not received by the Fund at a constant
rate throughout the year, such interest distribution may be more or less than
the amount credited to such Interest Account as of the record date. For the
purpose of minimizing fluctuations in the distributions from an 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 for any such advances from funds in the applicable
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, under the
applicable plan of distribution.

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 Fund (as
determined on the basis set forth under "Trust Administration--Fund
Administration and 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 Fund. Amounts so withdrawn
shall not be considered a part of the Fund'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 purchases of
Replacement Bonds and redemptions of Units by the Trustee.

Reinvestment Option. Unitholders of all unit investment trusts sponsored by
Van Kampen American Capital Distributors, Inc., may elect to have each
distribution of interest income, capital gains and/or principal on their Units
automatically reinvested in shares of any Van Kampen American Capital mutual
funds (except for B shares) 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 Trusts. The prospectus relating to each
Reinvestment Fund describes the investment policies of such fund and sets
forth the procedures to follow to commence reinvestment. A Unitholder may
obtain a prospectus for the respective Reinvestment Funds from Van Kampen
American Capital Distributors, Inc. at One Parkview Plaza, Oakbrook Terrace,
Illinois 60181. Texas residents who desire to reinvest may request that a
broker-dealer registered in Texas send the prospectus relating to the
respective fund.

After becoming a participant in a reinvestment plan, each distribution of
interest income, capital gains and/or principal on the participant's Units
will, on the applicable distribution date, automatically be applied, as
directed by such person, as of such distribution date by the Trustee to
purchase shares (or fractions thereof) of the applicable Reinvestment Fund at
a net asset value as computed as of the close of trading on the New York Stock
Exchange on such date. Unitholders with an existing Guaranteed Reinvestment
Option (GRO) Program account (whereby a sales charge is imposed on
distribution reinvestments) may transfer their existing account into a new GRO
account which allows purchases of Reinvestment Fund shares at net asset value
as described above.

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 of 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.

Unitholders of New York Trusts, other than residents of Massachusetts, may
elect to have distributions reinvested in shares of First Investors New York
Insured Tax Free Fund, Inc. subject to a sales charge of $1.50 per $100
reinvested (paid to First Investors Management Company, Inc.).

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 (or by written request if Units are not held in
certificated form), 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 third business day following such tender 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.

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

The Redemption Price per Unit (as well as the secondary market Public Offering
Price) will be determined on the basis of the bid price of the Securities in
each Trust, while the initial and primary Public Offering Price of Units will
be determined on the basis of the offering price of the Securities in each
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. On the Date of Deposit
the Public Offering Price per Unit (which is based on the offering prices of
the Bonds in each Trust and includes the sales charge) exceeded the value at
which Units could have been redeemed (based upon the current bid prices of the
Securities in such Trust) by the amount shown under "Summary of Essential
Financial Information". 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 each Trust on the basis of (i) the cash on hand in such Trust or
moneys in the process of being collected, (ii) the value of the Securities in
such Trust based on the bid prices of the Securities therein, except for cases
in which the value of insurance has been included, (iii) interest accrued
thereon, less (a) amounts representing taxes or other governmental charges
payable out of such Trust and (b) the accrued expenses of such Trust. The
Evaluator may determine the value of the Securities in each Trust by employing
any of the methods set forth in "Public Offering--Offering Price". In
determining the Redemption Price per Unit no value will be assigned to the
portfolio insurance maintained on the Bonds in an Insured Trust unless such
Bonds are in default in payment of principal or interest or in significant
risk of such default. For a description of the situations in which the
Evaluator may value the insurance obtained by the Insured Trusts, see 
"Public Offering--Offering Price" above.

The price at which Units may be redeemed could be less than the price paid by
the Unitholder and may be less than the par value of the Securities
represented by the Units so redeemed. As stated above, the Trustee may sell
Securities to cover redemptions. When Securities are sold, the size and
diversity of the affected 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 Trusts 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.

Reports Provided. The Trustee shall furnish Unitholders of a Trust in
connection with each distribution a statement of the amount of interest and
the amount of other receipts (received since the preceding distribution), if
any, being distributed expressed in each case as a dollar amount representing
the pro rata share of each Unit of a Trust outstanding. For as long as the
Trustee deems it to be in the best interests of the Unitholders, the accounts
of each 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 of such Trusts 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 of a Trust 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, deductions for
applicable taxes and for fees and expenses of such Trust, for purchases of
Replacement Bonds and 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 purchases of Replacement Bonds and 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 a Trust furnished to it by the Evaluator.

Each distribution statement of a Trust will reflect pertinent information in
respect of the other plan of distribution so that Unitholders may be informed
regarding the results of such other plan of distribution.

INSURANCE ON THE BONDS IN THE INSURED TRUSTS

Insurance has been obtained by each Insured 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 a Trust guaranteeing prompt payment of interest and
principal, when due, in respect of the Bonds in such Trust. See 
"Unitholder Explanations--Settlement of Bonds in the Trusts--Objectives and
Securities Selection". An insurance policy obtained by an Insured Trust,
if any, is non-cancellable and will continue in force so long as such Trust is
in existence, the respective Portfolio Insurer referred to below is still in
business and the Bonds described in such policy continue to be held by such
Trust (see "Portfolio" for the respective Insured Trust). Any
portfolio insurance premium for an Insured Trust, which is an obligation of
such Trust, is paid by each Trust on a monthly basis. Non-payment of premiums
on a policy obtained by an Insured 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 such Trust. Premium rates for each issue of Bonds
protected by a policy obtained by an Insured 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 an Insured 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 an Insured 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 affected 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 an Insured Trust, if any, is only effective as to
Bonds owned by and held in such 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
an Insured Trust, has the right to obtain permanent insurance with respect to
such Bond (i.e., insurance to maturity of the Bonds regardless of the identity
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 an Insured
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 affected 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 the creditworthiness of each Bond.

The Sponsor believes that the Permanent Insurance option provides an advantage
to an Insured Trust in that each Bond insured by a Trust insurance policy may
be sold out of the affected 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--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 an Insured Trust were to be comprised of a
substantial percentage of Bonds in default or significant risk of default, it
is much less likely that such Trust would need at some point in time to seek a
suspension of redemptions of Units than if such Trust were to have no such
option (see "Public Offering--Redemption of Units") and (b) at the
time of termination of an Insured Trust, if such Trust were holding defaulted
Bonds or Bonds in significant risk of default such Trust would not need to
hold such Bonds until their respective maturities in order to realize the
benefits of such Trust's portfolio insurance (see "Trust
Administration--Amendment or Termination").

Except as indicated below, insurance obtained by an Insured Trust 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. See "Public
Offering--Offering Price". 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--Offering
Price" herein for a more complete description of an Insured 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 an Insured Trust, if
any, with respect to the Bonds in such 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 
"Unitholder Explanations--Settlement of Bonds in the Trusts--Objectives and
Securities Selection".

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.

applicable statutory risk limitations. In addition, Financial Security
reinsures a portion of its liabilities under certain of its financial guaranty
insurance policies with unaffiliated reinsurers under various quota share
treaties and on a transaction-by-transaction basis. Such reinsurance is
utilized by Financial Security as a risk management device and to comply with
certain statutory and rating agency requirements; it does not alter or limit
Financial Security's obligations under any financial guaranty insurance policy.

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

the New York Stock Exchange under the symbol "KAP." Neither Holdings
nor any of its stockholders is obligated to pay any claims under any policy
issued by CapMAC or any debts of CapMAC or to make additional capital
contributions to CapMAC.

CapMAC is regulated by the Superintendent of Insurance of the State of New
York. In addition, CapMAC is subject to regulation by the insurance laws and
regulations of other jurisdictions in which it is licensed. Such insurance
laws regulate, among other things, the amount of net exposure per risk that

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

THE POLICY IS NOT COVERED BY THE PROPERTY/CASUALTY INSURANCE SECURITY FUND

As at December 31, 1995 and 1994, CapMAC had qualified statutory capital
(which consists of policyholders' surplus and contingency reserve) of
approximately $240 million and $170 million, respectively, and had not
incurred any debt obligations. Article 69 of the New York State Insurance Law
requires CapMAC to establish and maintain the contingency reserve, which is
available to cover claims under policies issued by CapMAC.

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.

In order to be in an Insured Trust, Bonds must be insured by one of the
Preinsured Bond Insurers or be eligible for the insurance being obtained by
such 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 an Insured Trust.
Thus, all of the Bonds in the portfolios of the Insured Trusts in the Fund are
insured either by the respective 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 a Trust.

Because the Bonds are insured by one of the Portfolio Insurers or one of the
Preinsured Bond Insurers as to the timely payment of principal and interest,
when due, and on the basis of the various reinsurance agreements in effect,
Standard & Poor's has assigned to the Units of each Insured Trust its 
"AAA" investment rating. Such rating will be in effect for a period of
thirteen months from the Date of Deposit and will, unless renewed, terminate
at the end of such period. See "Description of Securities Ratings".
The obtaining of this rating by an Insured Trust should not be construed as an
approval of the offering of the Units by Standard & Poor's or as a guarantee
of the market value of such Trust or of the Units.

 
On the date of this Prospectus, the Estimated Current Return on the Securities
in the Tennessee IM-IT Trust was 5.20% based on the monthly plan of
distribution after payment of the insurance premium or premiums payable by
such Trust, while the Estimated Long-Term Return on such Trust was 5.19%. The
Estimated Current Return on an identical portfolio without the insurance
obtained by the above mentioned Trust would have been 5.26% based on the
monthly plan of distribution on such date, while the Estimated Long-Term
Return on an identical portfolio without the insurance obtained by the above
mentioned Trust would have been 5.25%.
 

An objective of portfolio insurance obtained by an Insured Trust is to obtain
a higher yield on the portfolio of such Trust than would be available if all
the Securities in such portfolio had Standard & Poor's "AAA" rating
and yet at the same time to have the protection of insurance of prompt payment
of interest and principal, when due, on the Bonds. There is, of course, no
certainty that this result will be achieved. Preinsured Bonds in an Insured
Trust (all of which are rated "AAA" by Standard & Poor's) may or may
not have a higher yield than uninsured bonds rated "AAA" by Standard &
Poor's. In selecting such Bonds for an Insured Trust, 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
an Insured 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 an Insured 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
"Other Matters--Federal Tax Status".

Each Portfolio Insurer is subject to regulation by the department of insurance
in the 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 contract 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 any such company to meet
its commitment 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.

The Bonds in the Insured Trusts are insured as follows:

IM-IT   

General. The IM-IT consists of 12 issues of Securities. Two of the Bonds in
the IM-IT are general obligations of the governmental entities issuing them
and are backed by the taxing power thereof. The remaining issues are payable
from the income of a specific project or authority and are not supported by
the issuer's power to levy taxes. These issues are located in 10 states or
territories, divided by purpose of issues (and percentage of principal amount
to total IM-IT) as follows: Health Care, 4 (33%); General Obligations, 2
(22%); Retail Electric/Gas, 2 (16%); Higher Education, 1 (11%); Water and
Sewer, 1 (11%); Airport, 1 (5%) and Public Building, 1 (2%). No Bond issue has
received a provisional rating. The dollar weighted average maturity of the
Bonds in the Trust is 31 years.

Tax Status. For a discussion of the Federal tax status of income earned on
IM-IT Trust Units, see "Other Matters--Federal Tax Status".

<F3>The Estimated Current Returns and Estimated Long-Term Returns are increased
for transactions entitled to a reduced sales charge. See "Unitholder
Explanations--Public Offering--General".

<F4>The 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; therefore, there is no assurance that the present Estimated
Current Returns indicated above will be realized in the future. The 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 as indicated
above will be realized in the future. The Estimated Current Returns and
Estimated Long-Term Returns are expected to differ because the calculation of
the Estimated Long-Term Return reflects the estimated date and amount of
principal returned while the Estimated Current Return calculation includes
only net annual interest income and Public Offering Price.

<F5>These figures are based on estimated per Unit cash flows. Estimated cash flows
will vary with changes in fees and expenses, with changes in current interest
rates and with the principal prepayment, redemption, maturity, call, exchange
or sale of the underlying Securities. The estimated cash flows for this Series
are set forth under "Estimated Cash Flows to Unitholders".

TENNESSEE IM-IT TRUST 

General. The Tennessee IM-IT Trust consists of 8 issues of Securities. One of
the Bonds in the Tennessee IM-IT Trust is a general obligation of the
governmental entity issuing it and is backed by the taxing power thereof. The
remaining issues are payable from the income of a specific project or
authority and are not supported by the issuer's power to levy taxes. These
issues are divided by purpose of issues (and percentage of principal amount to
total Tennessee IM-IT Trust) as follows: Water and Sewer, 3 (37%); Health
Care, 1 (17%); Industrial Revenue, 1 (17%); Multi-Family Mortgage Revenue, 1
(17%); Public Education, 1 (8%) and General Obligations, 1 (4%). No Bond issue
has received a provisional rating.

Risk Factors. The following brief summary regarding the economy of Tennessee
is based upon information drawn from publicly available sources and is
included for the purpose of providing information about general economic
conditions that may or may not affect issuers of the Tennessee obligations.
The Sponsor has not independently verified any of the information contained in
such publicly available documents.

The State Constitution of Tennessee requires a balanced budget. No legal
authority exists for deficit spending from operating purposes beyond the end
of a fiscal year. Tennessee law permits tax anticipation borrowing but any
amount borrowed must be repaid during the fiscal year for which the borrowing
was done. Tennessee has not issued any debt for operating purposes during
recent years with the exception of some advances which were made from the
Federal Unemployment Trust Fund in 1984. No such advances are now outstanding
nor is borrowing of any type for operating purposes contemplated.

The State Constitution of Tennessee forbids the expenditure of the proceeds of
any debt obligation for a purpose other than the purpose for which it was
authorized by statute. Under State law, the term of bonds authorized and
issued cannot exceed the expected life of the projects being financed.
Furthermore, the amount of a debt obligation cannot exceed the amount
authorized by the General Assembly. The recommended State budget for Fiscal
Year 1994-95 is $12,570,380,800. State revenues are scheduled to be obtained
from taxes, each of which will generate a certain percentage of the total
revenues as follows: sales (54%); franchise and excise (12%); gasoline (11%);
gross receipts and privilege (4%); motor vehicle (3%); income and inheritance
(3%); insurance and banking (3%); tobacco, beer, and alcoholic beverages (2%)
and all other taxes (8%).

For Fiscal Year 1994-95, State revenues are scheduled to be allocated in the
following percentages: education (44%); health and social services (22%);
transportation (11%); law, safety and correction (9%); cities and counties
(8%); general government (3%); resources and regulation (2%) and business and
economic development (1%).

Overall, the economic indicators were positive for Tennessee for 1993. After a
slow start, inflation-adjusted personal income in Tennessee rebounded in the
second quarter, resulting in overall growth of 4.4% from the second quarter of
1992 to the second quarter of 1993. Tennessee's employment also grew in 1993,
although its growth was not as impressive as income growth. Third-quarter
statistics for 1993 show that Tennessee nonagricultural employment was 1.7%
above the same quarter in 1992. In 1994, the Tennessee economy continued to
expand. From December, 1993 to December, 1994 Tennessee's seasonally adjusted
employment grew from 2,395,100 people to 2,567,300 people, while its
unemployment rate decreased from 4.6% to 3.8% over that same period.

An increase in consumer spending is reflected in Tennessee taxable sales,
which grew 10.4% from the third quarter of 1992 to the third quarter of 1993.
Long-term average growth for taxable sales 8.5%, but the distinction between
this figure and the recent 10.4% figure is more substantial than first
appearances suggest because the long-term average includes some periods of
significantly higher inflation than the most resent quarters. Adjusted for
inflation, taxable sales grew by 7.5% from the third quarter of 1992 to the
third quarter of 1993, which is triple the long-term inflation-adjusted
average of 2.5%.

The largest contributor to Tennessee's employment growth is services,
accounting for 40.9% of the employment growth that occurred from the third
quarter of 1992 to the third quarter of 1993. While it is still the most
substantial source of employment growth for Tennessee, services has
historically grown at a higher rate. Similarly, the large trade sector is not
as dominant, contributing 27.8% of employment growth from the third quarter of
1992 to the third quarter of 1993. Another sector that has become less
influential on total employment growth in Tennessee is the finance, insurance,
and real estate industry, which contributed nothing to employment growth
during the year ending in the third quarter of 1993.

Tennessee's general obligation bonds are rated Aaa by Moody's and AA+ by
Standard & Poor's. Tennessee's smallest counties have Moody's lowest rating
due to these rural counties' limited economies that make them vulnerable to
economic downturns.

Tennessee is involved in certain legal proceedings that, if decided against
the State, may require the State to make significant future expenditures or
may substantially impair revenues. The Tennessee Supreme Court currently is
reviewing a case in which the lower court found that the Tennessee Department
of Revenue improperly defined non-business earnings for tax purposes. Although
this case involves only $925,000, its outcome could affect at least five other
cases and could have a detrimental impact to Tennessee's revenue base. If the
case is affirmed, Tennessee could lose an estimated $80 million to $100
million a year in corporate income taxes. The Tennessee Supreme Court also may
hear a similar case in which the lower court found that the taxpayer's partial
sale of business holdings resulted in taxable business income. A ruling in
favor of the taxpayer could result in a $10 million tax refund.

Two other tax related cases could also affect the State's financial condition.
A recently filed class-action suit seeks damages in excess of $25 million for
the allegedly illegal collection of sales taxes paid on extended warranty
contracts on motor vehicles. In addition, a coalition of more than a dozen
hospitals is considering a class-action suit to challenge the legality of
Tennessee's Medicaid service tax. Tennessee's hospitals currently pay
approximately $504 million dollars in special taxes.

The foregoing information does not purport to be a complete or exhaustive
description of all the conditions to which the issuers of Bonds in the
Tennessee IM-IT Trust are subject. Many factors including national economic,
social and environmental policies and conditions, which are not within the
control of the issuers of Bonds, could affect or could have an adverse impact
on the financial condition of the State and various agencies and political
subdivisions located in the State. Since certain Bonds in the Tennessee IM-IT
Trust (other than general obligation bonds issued by the State) are payable
from revenue derived from a specific source or authority, the impact of a
pronounced decline in the national economy or difficulties in significant
industries within the State could result in a decrease in the amount of
revenues realized from such source or by such authority and thus adversely
affect the ability of the respective issuers of the Bonds in the Tennessee
IM-IT Trust to pay the debt service requirements on the Bonds. Similarly, such
adverse economic developments could result in a decrease in tax revenues
realized by the State and thus could adversely affect the ability of the State
to pay the debt service requirements of any Tennessee general obligation bonds
in the Tennessee IM-IT Trust. The Sponsor is unable to predict whether or to
what extent such factors or other factors may affect the issuers of Bonds, the
market value or marketability of the Bonds or the ability of the respective
issuers of the Bonds acquired by the Tennessee IM-IT Trust to pay interest on
or principal of the Bonds.

Tax Status. For a discussion of the federal tax status of income earned on
Tennessee IM-IT Trust Units, see "Other Matters--Federal Tax Status." 

The assets of the Tennessee IM-IT Trust will consist of bonds issued by the
State of Tennessee (the "State") or any county or any municipality or
political subdivision thereof, including any agency, board, authority or
commission, the interest on which is exempt from the Hall Income Tax imposed
by the State of Tennessee ("Tennessee Bonds") or by the Commonwealth
of Puerto Rico (the "Puerto Rico Bonds") (collectively, the "Bonds").

Under Tennessee law, a unit investment trust taxable as a grantor trust for
federal income tax purposes is entitled to special Tennessee State tax
treatment (as more fully described below) with respect to its proportionate
share of interest income received or accrued with respect to the Tennessee
Bonds. The recent amendments also provide an exemption for distributions made
by a unit investment trust or mutual fund that are attributable to "bonds
or securities of the United States government or any agency or instrumentality
thereof" ("U.S. Government, Agency or Instrumentality Bonds"). If
it were determined that the Trust held assets other than Tennessee Bonds or
U.S. Government, Agency or Instrumentality Bonds, a proportionate share of
distributions from the Trust would be taxable to Unitholders for Tennessee
Income Tax purposes.

Further, this provision appears only to provide an exemption for distributions
that relate to interest income, distributions by the Trust that relate to
capital gains realized from the sale or redemption of Tennessee Bonds or U.S.
Government, Agency or Instrumentality Bonds are likely to be treated as
taxable dividends for purposes of the Hall Income Tax. However, capital gains
realized directly by a Unitholder when the Unitholder sells or redeems his
Unit will not be subject to the Hall Income Tax. The opinion set forth below
assumes that the interest on the Tennessee Bonds, if received directly by a
Unitholder, would be exempt from the Hall Income Tax under Tennessee State
law. This opinion does not address the taxation of persons other than
full-time residents of the State of Tennessee.

Because this provision only provides an exemption for distributions
attributable to interest on Tennessee Bonds or U.S. Government, Agency or
Instrumentality Bonds, it must be determined whether bonds issued by the
Government of Puerto Rico qualify as U.S. Government, Agency or
Instrumentality Bonds. For Hall Income Tax purposes, there is currently no
published administrative interpretation or opinion of the Attorney General of
Tennessee dealing with the status of distributions made by unit investment
trusts such as the Tennessee Trust that are attributable to interest paid on
bonds issued by the Government of Puerto Rico. However, in a letter dated
August 14, 1992 (the "Commissioner's Letter"), the Commissioner of
the State of Tennessee Department of Revenue advised that Puerto Rico would be
an "instrumentality" of the U.S. Government and treated bonds issued
by the Government of Puerto Rico as U.S. Government, Agency or Instrumentality
Bonds. Based on this conclusion, the Commissioner advised that distributions
from a mutual fund attributable to investments in Puerto Rico Bonds are exempt
from the Hall Income Tax. Both the Sponsor and Chapman and Cutler, for
purposes of its opinion (as set forth below), have assumed, based on the
Commissioner's Letter, that bonds issued by the Government of Puerto Rico are
U.S. Government, Agency or Instrumentality Bonds. However, it should be noted
that the position of the Commissioner is not binding, and is subject to
change, even on a retroactive basis.

The Sponsor cannot predict whether new legislation will be enacted into law
affecting the tax status of Tennessee IM-IT Trusts. The occurrence of such an
event could cause distributions of interest income from the Trust to be
subject to the Hall Income Tax. Investors should consult their own tax
advisors in this regard.

In the opinion of Chapman and Cutler, Counsel to the Sponsor, under existing
Tennessee State law as of the date of this prospectus:

For purposes of the Hall Income Tax, the Tennessee Excise Tax imposed by
Section 67-4-806 (the "State Corporate Income Tax"), and the Tennessee
Franchise Tax imposed by Section 67-4-903, the Tennessee IM-IT Trust will not
be subject to such taxes.

For Hall Income Tax purposes, a proportionate share of such distributions from
the Tennessee IM-IT Trust to Unitholders, to the extent attributable to
interest on the Tennessee Bonds (based on the relative proportion of interest
received or accrued attributable to Tennessee Bonds) will be exempt from the
Hall Income Tax when distributed to such Unitholders. Based on the
Commissioner's Letter, distributions from the Trust to Unitholders, to the
extent attributable to interest on the Puerto Rico Bonds (based on the
relative proportion of interest received or accrued attributable to the Puerto
Rico Bonds) will be exempt from the Hall Income Tax when distributed to such
Unitholders. A proportionate share of distributions from the Tennessee IM-IT
Trust attributable to assets other than the Bonds would not, under current
law, be exempt from the Hall Income Tax when distributed to Unitholders.

For Tennessee State Corporate Income Tax Purposes, Tennessee law does not
provide an exemption for interest on Tennessee Bonds and requires that all
interest excludible from Federal gross income must be included in calculating
"net earnings" subject to the State Corporate Income Tax. No opinion
is expressed regarding whether such tax would be imposed on the earnings or
distributions of the Tennessee IM-IT Trust (including interest on the Bonds or
gain realized upon the disposition of the Bonds by the Tennessee IM-IT Trust)
attributable to Unitholders subject to the State Corporate Income Tax.
However, based upon prior written advice from the Tennessee Department of
Revenue, earnings and distributions from the Tennessee IM-IT Trust (including
interest on the Tennessee Bonds or gain realized upon the disposition of the
Tennessee Bonds by the Tennessee IM-IT Trust) attributable to the Unitholders
should be exempt from the State Corporate Income Tax. The position of the
Tennessee Department of Revenue is not binding, and is subject to change, even
on a retroactive basis.

Each Unitholder will realize taxable gain or loss for State Corporate Income
Tax purposes when the Unitholder redeems or sells his Units, at a price that
differs from original cost as adjusted for accretion or any discount or
amortization of any premium and other basis adjustments, including any basis
reduction that may be required to reflect a Unitholder's share of interest,
if any, accruing on Bonds during the interval between the Unitholder's
settlement date and the date such Bonds are delivered to the Tennessee IM-IT
Trust, if later. Tax basis reduction requirements relating to amortization of
bond premium may, under some circumstances, result in Unitholders realizing
taxable gain when the Units are sold or redeemed for an amount equal to or
less than their original cost.

For purposes of the Tennessee Property Tax, the Tennessee IM-IT Trust will be
exempt from taxation with respect to the Bonds it holds. As for the taxation
of the Units held by the Unitholders, although intangible personal property is
not presently subject to Tennessee taxation, no opinion is expressed with
regard to potential property taxation of the Unitholders with respect to the
Units because the determination of whether property is exempt from such tax is
made on a county by county basis.

No opinion is expressed herein regarding whether insurance proceeds paid in
lieu of interest on the Bonds held by the Tennessee IM-IT Trust (including the
Tennessee Bonds) are exempt from the Hall Income Tax. Distributions of such
proceeds to Unitholders may be subject to the Hall Income Tax.

The Bonds and the Units held by the Unitholder will not be subject to
Tennessee sales and use taxes.

We have not examined any of the Bonds to be deposited and held in the
Tennessee Trust or the proceedings for the issuance thereof or the opinions of
bond counsel with respect thereto, and therefore express no opinion as to the
exemption from State income taxes of interest on the Bonds if received
directly by a Unitholder.

Chapman and Cutler has expressed no opinion with respect to taxation under any
other provision of Tennessee law. Ownership of the Units may result in
collateral Tennessee tax consequences to certain taxpayers. Prospective
investors should consult their tax advisors as to the applicability of any
such collateral consequences.

<F1>Excluding insurance costs. The Estimated Annual Expenses are expected to
fluctuate periodically (see "Trust Administration--Fund Administration and
Expenses--Miscellaneous Expenses").

<F2>The Estimated Current Returns and Estimated Long-Term Returns are increased
for transactions entitled to a reduced sales charge. See "Unitholder
Explanations--Public Offering--General".

<F3>The 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; therefore, there is no assurance that the present Estimated
Current Returns indicated above will be realized in the future. The 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 as indicated
above will be realized in the future. The Estimated Current Returns and
Estimated Long-Term Returns are expected to differ because the calculation of
the Estimated Long-Term Return reflects the estimated date and amount of
principal returned while the Estimated Current Return calculation includes
only net annual interest income and Public Offering Price.

<F4>These figures are based on estimated per Unit cash flows. Estimated cash flows
will vary with changes in fees and expenses, with changes in current interest
rates and with the principal prepayment, redemption, maturity, call, exchange
or sale of the underlying Securities. The estimated cash flows for this Series
are set forth under "Estimated Cash Flows to Unitholders".

All of the Bonds in the portfolio are insured either by one of the Preinsured
Bond Insurers (as indicated in the Bond name) or under the portfolio insurance
policy obtained by the Trust from AMBAC Indemnity. See "Unitholder
Explanations--Insurance on the Bonds in the Insured Trusts".

For an explanation of the footnotes used on this page, see "Notes to
Portfolios". 
 

 
As of the Date of Deposit: May 2, 1996

(1)All Securities are represented by "regular way" or "when
issued" contracts for the performance of which an irrevocable letter of
credit, obtained from an affiliate of the Trustee, has been deposited with the
Trustee. At the Date of Deposit, Securities may have been delivered to the
Sponsor pursuant to certain of these contracts; the Sponsor has assigned to
the Trustee all of its right, title and interest in and to such Securities.
Contracts to acquire Securities were entered into during the period from April
17, 1996 to May 1, 1996. These Securities have expected settlement dates 
ranging from May 2, 1996 to May 14, 1996 (see "Unitholder Explanations").
 

(2)All ratings are by Standard & Poor's unless otherwise indicated. "*" 
 indicates that the rating of the Bond is by Moody's Investors Service, Inc.
The ratings represent the latest published ratings by the respective ratings
agency or, if not published, represent private letter ratings or those ratings
expected to be published by the respective ratings agency. "Y" 
indicates that such rating is contingent upon physical receipt by the
respective ratings agency of a policy of insurance obtained by the issuer of
the bonds involved and issued by the Preinsured Bond Insurer named in the
bond's title. A commitment for insurance in connection with these bonds has
been issued by the Preinsured Bond Insurer named in the bond's title. "
N/R" indicates that the applicable rating service did not provide a rating
for that particular Security. For a brief description of the rating symbols
and their related meanings, see "Other Matters--Description of Securities
Ratings".

(3)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
valuation which represents a premium over par. Certain Bonds may be subject to
redemption without premium prior to the date shown pursuant to extraordinary
optional or mandatory redemptions if certain events occur. Single family
mortgage revenue bonds and housing authority bonds are most likely to be
called subject to such provisions, but other bonds may have similar call
features. Notwithstanding any provisions to the contrary, certain bond issuers
have in the past and others may in the future attempt to redeem Bonds prior to
their initially scheduled call dates and at prices which do not include any
premiums. For a general discussion of certain of these events, see 
"Unitholder Explanations--Bond Redemptions". To the extent that the
Securities were deposited in a Trust at a price higher than the price at which
they are redeemed, this will represent a loss of capital when compared with
the original Public Offering Price of the Units. Conversely, to the extent
that the Bonds were acquired at a price lower than the redemption price, this
will represent an increase in capital when compared with the original Public
Offering Price of the Units. Distributions will generally be reduced by the
amount of the income which would otherwise have been paid with respect to
redeemed Securities and there will be distributed to Unitholders the principal
amount and any premium received on such redemption. The Estimated Current
Return and Estimated Long-Term 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 (2) under "Other Matters--Federal
Tax Status".

(4)Evaluation of Securities is made on the basis of current offering prices
for the Securities. The offering prices are greater than the current bid
prices of the Securities which is the basis on which Unit value is determined
for purposes of redemption of Units (see "Unitholder Explanations--Public
Offering--Offering Price").

Deposit, is as follows:

The Sponsor may have entered into contracts which hedge interest rate
fluctuations on certain Bonds in certain Portfolios. The cost of any such
contracts and the corresponding gain or loss is included in the Cost to
Sponsor. Certain Securities in the Fund, if any, marked by a double asterisk
(**), have been purchased on a "when, as and if issued" or

the benefit of Unitholders on their respective dates of delivery. Delivery is
expected to take place at various dates after the First Settlement Date as

On the Date of Deposit, the offering side evaluations of the Securities in the
IM-IT and Tennessee IM-IT Trusts were higher than the bid side evaluations of
such Securities by 0.74% and 0.76%, respectively, of the aggregate principal
amounts of such Securities.

"#" indicates that such Bond was issued at an original issue discount.
The tax effect of Bonds issued at an original issue discount is described in
"Other Matters--Federal Tax Status".

(6)This Bond has been purchased at a deep discount from the par value because
there is little or no stated interest income thereon. Bonds which pay no
interest are normally described as "zero coupon" bonds. Over the life
of bonds purchased at a deep discount the value of such bonds will increase
such that upon maturity the holders of such bonds will receive 100% of the
principal amount thereof. To the extent that zero coupon bonds are sold or
called prior to maturity, there is no guarantee that the value of the proceeds
received therefrom by the Trust will equal or exceed the par value that would
have been obtained at maturity of such zero coupon bonds. Approximately 2% of
the aggregate principal amount of the Securities in the IM-IT Trust are 
"zero coupon" bonds.

Units may also be sold to broker-dealers and others at prices representing the
per Unit concession or agency commission stated under "Trust
Administration--General--Unit Distribution". However, resales of Units by
such broker-dealers and others to the public will be made at the Public
Offering Price described in the Prospectus. The Sponsor reserves the right to
reject, in whole or in part, any order for the purchase of Units and the right
to change the amount of the concession or agency commission from time to time.

In addition to any other benefits the Underwriters may realize from the sale
of the Units of the Fund, the Agreement Among Underwriters provides that the
Sponsor will share on a pro rata basis among those Underwriters who underwrite
at least 250 Units 50% of the aggregate gain, if any, represented by the
difference between the Sponsor's cost of the Securities in connection with
their acquisition and the evaluation thereof on the Date of Deposit less
deductions for certain accrued interest and certain other costs. See "
Trust Administration--General--Sponsor and Underwriter Compensation" and
"Portfolio" for the applicable Trust.

Underwriters and broker-dealers of the Trusts, banks and/or others are
eligible to participate in a program in which such firms receive from the
Sponsor a nominal award for each of their 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 Underwriters,
brokers, dealers, banks 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 Underwriters, brokers, dealers, banks 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 underwriters, brokers,
dealers, banks or others for certain services or activities which are
primarily intended to result in sales of Units of the Trusts. Such payments
are made by the Sponsor out of its own assets, and not out of the assets of
the Trusts. These programs will not change the price Unitholders pay for their
Units or the amount that the Trusts will receive from the Units sold.
Approximately every eighteen months the Sponsor holds a business seminar which
is open to Underwriters that sell units of trusts it sponsors. The Sponsor
pays substantially all costs associated with the seminar, excluding
Underwriter travel costs. Each Underwriter is invited to send a certain number
of representatives based on the gross number of units such firm underwrites
during a designated time period.

FUND ADMINISTRATION AND EXPENSES

Sponsor. Van Kampen American Capital Distributors, Inc., a Delaware
corporation, is the Sponsor of the Trust. Van Kampen American Capital
Distributors, Inc. is primarily owned by Clayton, Dubilier & Rice, Inc., a New
York-based private investment firm. Van Kampen American Capital Distributors,
Inc. management owns a significant minority equity position. Van Kampen
American Capital Distributors, Inc. specializes in the underwriting and
distribution of unit investment trusts and mutual funds with roots in money
management dating back to 1926. The Sponsor is a member of the National
Association of Securities Dealers, Inc. and has offices at One Parkview Plaza,
Oakbrook Terrace, Illinois 60181, (708) 684-6000 and 2800 Post Oak Boulevard,
Houston, Texas 77056, (713) 993-0500. 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 December 31, 1995 the total
stockholders' equity of Van Kampen American Capital Distributors, Inc. was
$123,165,000 (unaudited). (This paragraph relates only to the Sponsor and not
to the Insured Municipals Income Trust or to any Insured Multi-Series thereof
or to any other Underwriter. The information is included herein only for the
purpose of informing investors as to the financial responsibility of the
Sponsor and its ability to carry out its contractual obligations. More
detailed financial information will be made available by the Sponsor upon
request.)

As of March 31, 1996, the Sponsor and its affiliates managed or supervised
approximately $57.2 billion of investment products, of which over $24.8
billion is invested in municipal securities. The Sponsor and its affiliates
managed $45.4 billion of assets, consisting of $22.5 billion for 63 open-end
mutual funds (of which 47 are distributed by Van Kampen American Capital
Distributors, Inc.), $11.9 billion for 38 closed-end funds and $5.6 billion
for 93 institutional accounts. The Sponsor has also deposited approximately
$26 billion of unit investment trusts. All of Van Kampen American Capital's
open-end funds, closed-end funds and unit investment trusts are professionally
distributed by leading financial firms nationwide. Based on cumulative assets
deposited, the Sponsor believes that it is the largest sponsor of insured
municipal unit investment trusts, primarily through the success of its Insured
Municipals Income Trust(R)or the IM-IT(R)trust. The Sponsor also
provides surveillance and evaluation services at cost for approximately $13
billion of unit investment trust assets outstanding. Since 1976, the Sponsor
has serviced over two million investor accounts, opened through retail
distribution firms. 

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 rates 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 Fund as provided therein
or (iii) continue to act as Trustee without terminating the Trust Agreement.

All costs and expenses incurred in creating and establishing the Fund,
including the cost of the initial preparation, printing and execution of the
Trust Agreement and the certificates, legal and accounting expenses,
advertising and selling expenses, expenses of the Trustee, initial evaluation
fees and other out-of-pocket expenses have been borne by the Sponsor at no
cost to the Fund.

Compensation of Sponsor and Evaluator. The Sponsor will not receive any fees
in connection with its activities relating to the Fund. However, American
Portfolio Evaluation Services, a division of Van Kampen American Capital
Investment Advisory Corp., which is an affiliate corporation of the Sponsor,
will receive an annual supervisory fee as indicated under "Summary of
Essential Financial Information" for providing portfolio supervisory
services for the Fund. Such fee (which is based on the number of Units
outstanding in each Trust on January 1 of each year) may exceed the actual
costs of providing such supervisory services for this Fund, but at no time
will the total amount received for portfolio supervisory services rendered to
Insured Municipals Income Trust, 1st Insured Multi-Series and subsequent
series and to any other unit investment trusts sponsored by the Sponsor for
which the Evaluator provides portfolio supervisory services 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
as indicated under "Summary of Essential Financial Information" for
regularly evaluating each 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 Underwriters will receive sales
commissions and may realize other profits (or losses) in connection with the
sale of Units and the deposit of the Securities as described under 
"General--Sponsor and Underwriter Compensation" below.

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 Bonds for the portfolios of any of the Trusts.

In accordance with the Trust Agreement, the Trustee shall keep proper books of
record and account of all transactions at its office for the Fund. Such
records shall include the name and address of, and the certificates issued by
the Fund to, every Unitholder of the Fund. 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 "Unitholder 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 Fund.

Under the Trust Agreement, the Trustee or any successor trustee may resign and
be discharged of the trusts 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 Fund
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.

 
Trustee's Fee. For its services the Trustee will receive a fee based on the
aggregate outstanding principal amount of Securities in each 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. During the first year
the Trustee may agree to reduce its fee (and to the extent necessary pay
miscellaneous expenses of a Trust) as stated under "Per Unit
Information" for the applicable Trust. After the first year such fee will
be computed at $.51 per $1,000 principal amount of Securities for that portion
of each Trust under the semi-annual distribution plan and $.91 per $1,000
principal amount of Securities for that portion of each Trust under the
monthly distribution plan. Based on the size of the Trust on the Date of
Deposit and assuming all Unitholders had chosen the semi-annual distribution
plan, the Trustee's estimated annual fees for ordinary recurring services
would initially amount to $4,618 and $1,530 for the IM-IT and Tennessee IM-IT
Trusts, respectively. Assuming in the alternative that all Unitholders had
elected the monthly distribution plan such fees would have initially amount to
$8,240 and $2,730 for the above mentioned Trusts, respectively. The Trustee's
fees are payable monthly on or before the twenty-fifth day of each month from
the Interest Account of each Trust to the extent funds are available and then
from the Principal Account of each Trust, with such payments being based on
each Trust's portion of such expenses. 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 each Trust is expected to result
from the use of these funds. 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. The Trustee's fees will not
be increased in future years in order to make up any reduction in the
Trustee's fees described under "Per Unit Information" for the
applicable Trust. For a discussion of the services rendered by the Trustee
pursuant to its obligations under the Trust Agreement, see "Unitholder
Explanations--Public Offering--Reports Provided" and "Trustee" 
above.
 

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 Securities, will consider a variety of factors,
including (a) interest rates, (b) market value and (c) marketability. In
connection with the Insured Trusts 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 such Trust's portfolio will tend to
diminish. Except as described in this section 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 from an Insured Trust which are in default in payment
of principal or interest or in significant risk of such default and for which
value has been attributed for the insurance obtained by such Insured 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 in an Insured Trust. See "Unitholder
Explanations--Public Offering--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 Securities to issue new obligations in exchange or
substitution for any Security 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 Security or (2) in
the written opinion of the Sponsor the issuer will probably default with
respect to such Security 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
Securities originally deposited thereunder. Within five days after the deposit
of obligations in exchange or substitution for underlying Securities, the
Trustee is required to give notice thereof to each Unitholder of the Trust
thereby affected, identifying the Securities eliminated and the Securities
substituted therefor. Except as stated herein and under "Unitholder
Explanations--Settlement of Bonds in the Trusts" regarding the
substitution of Replacement Bonds for Failed Bonds, the acquisition by the
Fund of any securities other than the Securities initially deposited is not
permitted.

If any default in the payment of principal or interest on any Security occurs
and no provision for payment is made therefor 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 Security within 30 days after notification by
the Trustee to the Sponsor of such default, the Trustee may in its discretion
sell the defaulted Security and not be liable for any depreciation or loss
thereby incurred.

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.

Insurance Premiums. The cost of the portfolio insurance obtained by the
respective Trusts, if any, is that amount shown in footnote (5) in "Notes
to Portfolios", so long as such Trust retains the Bonds. Premiums, which
are obligations of each Insured Trust, are payable monthly by the Trustee on
behalf of the respective Trust. As Bonds in the portfolio of an Insured Trust
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 such 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. A Trust does not incur any expense for Preinsured Bond
insurance, since the premium or premiums for such insurance have been paid by
the issuer or the Sponsor prior to the deposit of such Preinsured Bonds in a
Trust. Preinsured Bonds are not additionally insured by an Insured Trust.

Miscellaneous Expenses. The following additional charges are or may be
incurred by the Trusts: (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 Trusts
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 Fund without negligence, bad faith or willful misconduct
on its part, (f) any special custodial fees payable in connection with the
sale of any of the Bonds in a Trust, (g) expenditures incurred in contacting
Unitholders upon termination of the Trusts and (h) costs incurred to reimburse
the Trustee for advancing funds to the Trusts to meet scheduled distributions
(which costs may be adjusted periodically in response to fluctuations in
short-term interest rates).

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

GENERAL

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 Fund, except
for the substitution of certain refunding securities for such Securities. In
the event of any amendment, the Trustee is obligated to notify promptly all
Unitholders of the substance of such amendment.

 
A Trust may be terminated at any time by consent of Unitholders of 51% of the
Units of such Trust then outstanding or by the Trustee when the value of such
Trust, as shown by any semi-annual evaluation, is less than that indicated
under "Summary of Essential Financial Information". A Trust will be
liquidated by the Trustee in the event that a sufficient number of Units not
yet sold are tendered for redemption by the Underwriters, including the
Sponsor, so that the net worth of such Trust would be reduced to less than 40%
of the initial principal amount of such Trust. If a Trust is liquidated
because of the redemption of unsold Units by the Underwriters, the Sponsor
will refund to each purchaser of Units the entire sales charge paid by such
purchaser. The Trust Agreement provides that each Trust shall terminate upon
the redemption, sale or other disposition of the last Security held in such
Trust, but in no event shall it continue beyond the end of the year preceding
the fiftieth anniversary of the Trust Agreement in the case of an IM-IT or a
State Trust, or beyond the end of the year preceding the twentieth anniversary
of the Trust Agreement in the case of IM-IT Limited Maturity, IM-IT
Intermediate and IM-IT Short Intermediate Trusts. In the event of termination
of the Fund or any Trust, written notice thereof will be sent by the Trustee
to each Unitholder of such Trust at his address appearing on the registration
books of the Fund maintained by the Trustee. Within a reasonable time
thereafter the Trustee shall liquidate any Securities then held in such Trust
and shall deduct from the funds of such 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 or par 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 Unitholder 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 of an Insured Trust, it should be noted that because the portfolio
insurance obtained by an Insured Trust is applicable only while Bonds so
insured are held by such Trust, the price to be received by such 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 deteriorated market prices resulting
from a significant risk of default. Since the Preinsured Bonds 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 Preinsured 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 gross negligence 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 Fund
which the Trustee may be 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 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 of its obligations and duties.

Unit Distribution. During the initial offering period, Units will be
distributed to the public by Underwriters, broker-dealers and others (see 
"Underwriting") at the Public Offering Price, plus interest accrued but
unpaid from the First Settlement Date to the date of settlement as described
above under "Unitholder Explanations--Accrued Interest--Accrued
Interest". Upon the completion of the initial offering, Units repurchased
in the secondary market, if any, may be offered by this Prospectus at the
secondary Public Offering Price plus interest accrued to the date of
settlement in the manner described.

 
The Sponsor intends to qualify the Units for sale in a number of states.
Broker-dealers or others will be allowed a concession or agency commission in
connection with the distribution of Units during the initial offering period
of in the case of an IM-IT or a State Trust $30.00 per Unit for less than 100
Units, $36.00 per Unit for any single transaction of 100 to 249 Units, $38.00
per Unit for any single transaction of 250 to 499 Units, $39.00 per Unit for
any single transaction of 500 to 999 Units and $39.00 per Unit for any single
transaction of 1,000 or more Units, provided that such Units are acquired
either from the Sponsor (in the case of dealer transactions) or through the
Sponsor (in the case of transactions involving brokers or others). The
increased concession or agency commission is a result of the discount given to
purchasers for quantity purchases. See "Unitholder Explanations--Public
Offering--General". Certain commercial banks are making Units of the Fund
available to their customers on an agency basis. A portion of the sales charge
paid by these customers (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 Units of the Fund; 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. Any quantity discount (see "Unitholder Explanations--Public
Offering--General") provided to investors will be borne by the selling
dealer or agent. For secondary market transactions, such concession or agency
commission will amount to 70% of the applicable sales charge as determined
using the table found in "Unitholder Explanations--Public Offering".
 

Except as stated hereinafter, the minimum purchase requirement in the initial
offering period and in the secondary market is one Unit. In connection with
fully disclosed transactions with the Sponsor, the minimum purchase
requirement will be that number of Units set forth in the contract between the
Sponsor and the related broker or agent.

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. See "Underwriting".

Sponsor and Underwriter Compensation. The Underwriters will receive a gross
sales commission equal to that percentage of the Public Offering Price of the
Units as indicated under "Unitholder Explanations--Public
Offering--Offering Price" less any reduced sales charges for quantity
purchases as described under "Unitholder Explanations--Public
Offering--General".

 
The Sponsor will receive from the Underwriters the excess of such gross sales
commission over $35.00, $29.00, $27.00, $12.00 and $35.00 per Unit of any
IM-IT, IM-IT Limited Maturity, IM-IT Intermediate, IM-IT Short Intermediate
and other Insured Trusts, respectively, as of the Date of Deposit. In
connection with quantity sales to purchasers of any IM-IT or State Trust the
Underwriters will receive from the Sponsor commissions totalling $37.00 per
Unit for any single transaction of 100 to 249 Units, $39.00 per Unit for any
single transaction of 250 to 499 Units, $40.00 per Unit for any single
transaction of 500 to 999 Units and $39.00 per Unit for any single transaction
of 1,000 or more Units. A. G. Edwards & Sons, Inc. ("Edwards"), which
acts as a Managing Underwriter of Units of the various series of the IM-IT,
will receive from the Sponsor reimbursement for certain costs and further
compensation in the amount of $5.00 for each Unit of the IM-IT it underwrites.
Also, if Principal Financial Securities, Inc. commits (on the Date of Deposit)
to underwrite a total of 4,000 or more Units of this series of the IM-IT, any
other series of the IM-IT and/or any series of Texas Insured Municipals Income
Trust during any calendar month, then Principal Financial Securities, Inc.
will receive an additional $1.00 per Unit for each of the Units of such Trust
it commits to underwrite in said month. See "Unitholder
Explanations--Public Offering--General." Further, each Underwriter who
underwrites 1,000 or more Units in any Trust will receive additional
compensation from the Sponsor of $1.00 for each Unit it underwrites. In
addition, the Sponsor and certain of the Underwriters will realize a profit or
the Sponsor will sustain a loss, as the case may be, as a result of the
difference between the price paid for the Securities by the Sponsor and the
cost of such Securities to a Trust (which is based on the determination by
Interactive Data Corporation of the aggregate offering price of the underlying
Securities in such Trust on the Date of Deposit). See "Underwriting" 
and "Portfolio" for the applicable Trust and "Notes to
Portfolios". The Sponsor and the Underwriters may also realize profits or
sustain losses with respect to Securities deposited in each Trust which were
acquired by the Sponsor from underwriting syndicates of which they were
members. The Sponsor has participated as sole underwriter or as manager or as
a member of the underwriting syndicates from which none of the aggregate
principal amount of the Securities in the portfolios of the Fund were
acquired. The Underwriters may further realize additional profit or loss
during the initial offering period as a result of the possible fluctuations in
the market value of the Securities in each Trust after the Date of Deposit,
since all proceeds received from purchasers of Units (excluding dealer
concessions or agency commissions allowed, if any) will be retained by the
Underwriters. Affiliates of an Underwriter are entitled to the same dealer
concessions or agency commissions that are available to the Underwriter.
 

As stated under "Unitholder Explanations--Public Offering--Market for
Units", the Sponsor intends to, and certain of the other Underwriters may,
maintain a secondary market for the Units of the Fund. In so maintaining a
market, such person or persons will also 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 (which price is based on the bid
prices of the Securities in such Trust and includes a sales charge). In
addition, such person or persons 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.

OTHER MATTERS 

 
Legal Opinions. The legality of the Units offered hereby and certain matters
relating to Federal and Tennessee tax law have been passed upon by Chapman and
Cutler, 111 West Monroe Street, Chicago, Illinois 60603, as counsel for the
Sponsor. Kroll & Tract has acted as counsel for the Trustee and as special
counsel to the Fund for New York tax matters. None of the special counsel for
the Fund has expressed any opinion regarding the completeness or materiality
of any matters contained in this Prospectus other than the tax opinion set
forth under "Tax Status" relating to the Trust for which it has
provided an opinion.
 

Independent Certified Public Accountants. The statements of condition and the
related securities portfolios at the Date of Deposit included in this
Prospectus have been audited by Grant Thornton LLP, independent certified
public accountants, as set forth in their report in this prospectus, and are
included herein in reliance upon the authority of said firm as experts in
accounting and auditing.

FEDERAL TAX STATUS

In the opinion of Chapman and Cutler, counsel for the Sponsor, under existing
law:

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

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

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

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

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

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

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

Counsel for the Sponsor has also advised that under Section 265 of the Code,
interest on indebtedness incurred or continued to purchase or carry Units of a
Trust is not deductible for Federal income tax purposes. The Internal Revenue
Service has taken the position that such indebtedness need not be directly
traceable to the purchase or carrying of Units (however, these rules generally
do not apply to interest paid on indebtedness incurred to purchase or improve
a personal residence). Also, under Section 265 of the Code, certain financial
institutions that acquire Units would generally not be able to deduct any of
the interest expense attributable to ownership of such Units. On December 7,
1995, the U.S. Treasury Department released proposed legislation that, if
enacted, would generally extend the financial institution rules to all
corporations, effective for obligations acquired after the date of
announcement. Investors with questions regarding this issue should consult
with their tax advisers.

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

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

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

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

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

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

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

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

Ownership of the Units may result in collateral federal income tax
consequences to certain taxpayers, including, without limitation, corporations
subject to either the environmental tax or the branch profits tax, financial
institutions, certain insurance companies, certain S corporations, individual
recipients of Social Security or Railroad Retirement benefits and taxpayers
who may be deemed to have incurred (or continued) indebtedness to purchase or
carry tax-exempt obligations. Prospective investors should consult their tax
advisors as to the applicability of any collateral consequences. On December
7, 1995, the U.S. Treasury Department released proposed legislation that, if
adopted, could affect the United States federal income taxation of non-United
States Unitholders and the portion of the Trust's income allocable to
non-United States Unitholders.

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

DESCRIPTION OF SECURITIES RATINGS

Standard & Poor's, A Division of the McGraw-Hill Companies. A 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:

I. 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.

II. Nature of and provisions of the obligation.

III. 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 fluctuations.

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 grade 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.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of Insured Municipals Income Trust, 198th Insured
Multi-Series (IM-IT and Tennessee IM-IT Trusts):

We have audited the accompanying statements of condition and the related
portfolios of Insured Municipals Income Trust, 198th Insured Multi-Series
(IM-IT and Tennessee IM-IT Trusts) as of May 2, 1996. The statements of
condition and portfolios are the responsibility of the Sponsor. Our
responsibility is to express an opinion on such financial 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 irrevocable letters of credit deposited to
purchase tax-exempt securities by correspondence with the Trustee. An audit
also includes assessing the accounting principles used and significant
estimates made by 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 financial statements referred to above present fairly, in
all material respects, the financial position of Insured Municipals Income
Trust, 198th Insured Multi-Series (IM-IT and Tennessee IM-IT Trusts) as of May
2, 1996, in conformity with generally accepted accounting principles.

<F1>The aggregate value of the Securities listed under "Portfolio" for
each Trust herein, and their cost to such Trust are the same. The value of the
Securities is determined by Interactive Data Corporation on the bases set
forth under "Unitholder Explanations--Public Offering--Offering Price". 
The contracts to purchase tax-exempt Securities are collateralized by
irrevocable letters of credit which have been deposited with the Trustee in
and for the following amounts:

<F2>Insurance coverage providing for timely payment, when due, of all principal
and interest on the Bonds in the Insured Trusts has been obtained either by
such Trusts, by a prior owner of the Bonds, by the Sponsor prior to the
deposit of such Bonds or by the issuers of the Bonds involved. Such insurance
does not guarantee the market value of the Bonds or the value of the Units.
The insurance obtained by the Insured Trusts is effective only while Bonds
thus insured are held in such Trusts. Neither the bid nor offering prices of
the underlying Bonds or of the Units, absent situations in which bonds are in
default in payment of principal or interest or in significant risk of such
default, include value, if any, attributable to the insurance obtained by such
Trusts.

<F3>The aggregate public offering price (exclusive of interest) and the aggregate
sales charge are computed on the bases set forth under "Unitholder
Explanations--Public Offering--Offering Price" and "Trust
Administration--General--Sponsor and Underwriter Profits" and assume all
single transactions involve less than 100 Units. For single transactions
involving 100 or more Units, the sales charge is reduced (see "Unitholder
Explanations--Public Offering--General") resulting in an equal reduction
in both the Cost to investors and the Gross underwriting commission while the
Net interest to Unitholders remains unchanged.

<F4>The Trustee will advance to the Trust the amount of net interest accrued to
May 7, 1996, the First Settlement Date, for distribution to the Sponsor as the
Unitholder of record as of the First Settlement Date.

EQUIVALENT TAXABLE ESTIMATED CURRENT RETURN TABLES

As of the date of this prospectus, the following tables show the approximate
taxable estimated current returns for individuals that are equivalent to
tax-exempt estimated current returns under combined Federal and State taxes
(where applicable) using the published Federal and State tax rates (where
applicable) scheduled to be in effect in 1996. They incorporate increased tax
rates for higher income taxpayers that were included in the Revenue
Reconciliation Act of 1993. These tables illustrate approximately what you
would have to earn on taxable investments to equal the tax-exempt estimated
current return in your income tax bracket. The table assumes that Federal
taxable income is equal to State income subject to tax, and for cases in which
more than one State rate falls within a Federal bracket, the State rate
corresponding to the highest income within that Federal bracket is used. The
combined State and Federal tax rates shown reflect the fact that State tax
payments are currently deductible for Federal tax purposes. The table does not
reflect any local taxes or any taxes other than personal income taxes. The
tables do not show the approximate taxable estimated current returns for
individuals that are subject to the alternative minimum tax. The taxable
equivalent estimated current returns may be somewhat higher than the
equivalent returns indicated in the following tables for those individuals who
have adjusted gross incomes in excess of $117,950. The tables do not reflect
the effect of Federal or State limitations (if any) on the amount of allowable
itemized deductions and the deduction for personal or dependent exemptions or
any other credits. These limitations were designed to phase out certain
benefits of these deductions for higher income taxpayers. These limitations,
in effect, raise the marginal maximum Federal tax rate to approximately 44
percent for taxpayers filing a joint return and entitled to four personal
exemptions and to approximately 41 percent for taxpayers filing a single
return entitled to only one personal exemption. These limitations are subject
to certain maximums, which depend on the number of exemptions claimed and the
total amount of the taxpayer's itemized deductions. For example, the
limitation on itemized deductions will not cause a taxpayer to lose more than
80% of his allowable itemized deductions, with certain exceptions. See "
Other Matters--Federal Tax Status" for a more detailed discussion of
recent Federal tax legislation, including a discussion of provisions affecting
corporations.

A comparison of tax-free and equivalent taxable estimated current returns with
the returns on various taxable investments is one element to consider in
making an investment decision. The Sponsor may from time to time in its
advertising and sales materials compare the then current estimated returns on
the Trusts and returns over specified periods on other similar Van Kampen
American Capital sponsored unit investment trusts with returns on taxable
investments such as corporate or U.S. Government bonds, bank CDs and money
market accounts or money market funds, each of which has investment
characteristics that may differ from those of the Trusts. U.S. Government
bonds, for example, are backed by the full faith and credit of the U.S.
Government and bank CDs and money market accounts are insured by an agency of
the federal government. Money market accounts and money market funds provide
stability of principal, but pay interest at rates that vary with the condition
of the short-term debt market. The investment characteristics of the Trusts
are described more fully elsewhere in this Prospectus.

ESTIMATED CASH FLOWS TO UNITHOLDERS 

The tables below set forth the per Unit estimated monthly and semi-annual
distributions of interest and principal to Unitholders. The tables assume no
changes in expenses, no changes in the current interest rates, no exchanges,
redemptions, sales or prepayments of the underlying Securities prior to
maturity or expected retirement date and the receipt of principal upon
maturity or expected retirement date. To the extent the foregoing assumptions
change actual distributions will vary.
