Insured Municipals Income Trust, 165th Insured Multi-Series
   
IM-IT 333              Missouri IM-IT 84         Oklahoma  IM-IT 13
Michigan IM-IT 120 
    
   
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 four underlying separate unit investment trusts designated as Insured
Municipals Income Trust, Series 333 (the "IM-IT"), Michigan Insured
Municipals Income Trust, Series 120 (the "Michigan IM-IT Trust"),
Missouri Insured Municipals Income Trust, Series 84 (the "Missouri IM-IT
Trust") and Oklahoma Insured Municipals Income Trust, Series 13 (the "
Oklahoma IM-IT Trust"). The various trusts are collectively referred to
herein as the "Trusts", while the Michigan IM-IT, Missouri IM-IT and
Oklahoma IM-IT Trusts are sometimes collectively referred to herein as the
"State Trusts", and the IM-IT, Michigan IM-IT, Missouri IM-IT and
Oklahoma 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 19. 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
Corporation. Standard & Poor's Corporation has indicated that this rating is
not a recommendation to buy, hold or sell Units nor does it take into account
the extent to which expenses of 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 is equal to the aggregate offering price of
the Securities in such Trust's portfolio and cash, if any, in the Principal
Account held or owned by such Trust Fund plus the applicable sales charge plus
Purchased Interest and accrued interest, if any. After the initial public
offering period, the secondary market Public Offering Price of each Trust will
be equal to the aggregate bid price of the Securities in such Trust and cash,
if any, in the Principal Account held or owned by such Trust Fund plus the
applicable sales charge plus Purchased Interest and accrued interest, if any.
Sales charges for the Trusts in the initial market, expressed both as a
percentage of the Public Offering Price (excluding Purchased Interest) and as
a percentage of the aggregate offering price of the Securities, are set forth
in footnote (2) under "Summary of Essential Financial Information".
For sales charges in the secondary market, see "Unitholder
Explanations--Public Offering". 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. 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 Return and Estimated Long-Term Return 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) 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. 

Distributions. Purchasers of Units will receive distributions on a monthly
basis. See "Unitholder Explanations--Settlement of Bonds in the Trusts"
. Record dates will be the first day of each month. Distributions will be made
on the fifteenth day of the month subsequent to the respective record dates. 

Market for Units. Although not obligated to do so, the Sponsor, Van Kampen
Merritt 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 Purchased Interest; however,
during the initial offering period such prices will be based upon the
aggregate offering prices of the Securities plus Purchased Interest. 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 Purchased
Interest (see "Unitholder Explanations--Public Offering--Redemption of
Units"and "Unitholder Explanations--Public Offering--Market for
Units"). 

Reinvestment Option. 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".

<FN>
<FN1>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. 
    
<FN2>Sales charges for the Trusts, expressed as a percentage of the Public Offering
Price per Unit (excluding Purchased Interest) 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% (5.152%); an IM-IT Limited Maturity Trust -
4.3% (4.493%); an IM-IT Intermediate Trust - 3.9% (4.058%); an IM-IT Short
Intermediate Trust - 3.0% (3.093%). 

<FN3>Purchased Interest is a portion of the unpaid interest that has accrued on the
Bonds from the later of the last payment date on the Bonds or the date of
issuance thereof through the First Settlement Date and is included in the
calculation of the Public Offering Price. Purchased Interest will be
distributed to Unitholders as Units are redeemed or Securities mature or are
called. Anyone ordering Units for settlement after the First Settlement Date
will pay accrued interest from such date to the date of settlement (normally
five 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 other than the Purchased Interest already included therein. After the
initial offering period, the Sponsor's Repurchase Price per Unit will be
determined as described under the caption "Public Offering--Market for
Units."

<FN4>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
business on January 1 for each year thereafter.
</TABLE>


SETTLEMENT OF BONDS IN THE TRUSTS 
   
The Fund. Insured Municipals Income Trust, 165th 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 Merritt Inc., as Sponsor, American Portfolio
Evaluation Services, a division of Van Kampen Merritt Investment Advisory
Corp., as Evaluator, and The Bank of New York, as Trustee. 

The Fund consists of four 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 Indiana, Virginia and Washington may purchase Units of the IM-IT
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. 
    
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) Municipal Bond Investors Assurance 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
Corporation rating of "BBB-"or at least the Moody's Investors
Service, Inc. rating of "Baa", which in brief represent the lowest
ratings for securities of investment grade (see "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 Corporation. 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 Corporation 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 Corporation 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,
Purchased Interest 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 monthly. The first such distribution will be in the
amount indicated under "Per Unit Information"for the applicable Trust
and will be made on the fifteenth day of the month indicated under "
Initial Distribution"therein to Unitholders of record on the first day of
such month. Distribution of funds from the Principal Account, if any, will
also be made monthly, except under certain special circumstances (see "
Unitholder Explanations--Public Offering--Distributions of Interest and
Principal"). 

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. Certificates are
transferable by presentation and surrender to the Trustee properly endorsed or
accompanied by a written instrument or instruments of transfer. A Unitholder
must sign exactly as his name appears on the face of the certificate with the
signature guaranteed by a participant in the Securities Transfer Agents
Medallion Program ("STAMP") or such other signature guaranty program
in addition to, or in substitution for, STAMP, as may be accepted by the
Trustee. In certain instances the Trustee may require additional documents
such as, but not limited to, trust instruments, certificates of death,
appointments as executor or administrator or certificates of corporate
authority. Certificates will be issued in denominations of one Unit or any
multiple thereof. 

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 Return and the Estimated Long-Term Return 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 and with changes in the Purchased
Interest; 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 (1) the amounts paid by
Unitholders and (2) 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, without interest, 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 September 27, 1994. The first
record date for each Trust (November 1, 1994) is 34 days from such date. The
daily rates of estimated net annual interest income per Unit are $.16174,
$.15586, $.15383 and $.14686 for the IM-IT, Michigan IM-IT, Missouri IM-IT and
Oklahoma IM-IT Trusts, respectively. This amounts to $5.50, $5.30, $5.23 and
$4.99 for the IM-IT, Michigan IM-IT, Missouri IM-IT and Oklahoma IM-IT Trusts,
respectively. 

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

The Michigan IM-IT Trust accrues 

$5.30 to the first record date plus 
$46.80 which is 10 normal distributions at $4.68, and finally adding 
$4.01 which has accrued from September 1, 1995 until September 27, 1995 which
completes the 360 day cycle (26 days times the daily factor) 
Total $56.11 interest earned /$1,000.00 (Date of Deposit Public Offering
Price) = 5.61% Estimated Current Return as of the Date of Deposit. 
    
PURCHASED AND ACCRUED INTEREST 

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

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. 

As indicated in "Purchased Interest", accrued interest as of the First
Settlement Date includes Purchased Interest. In an effort to reduce the amount
of Purchased Interest which would otherwise have to be paid by Unitholders,
the Trustee may advance a portion of such accrued interest to the Sponsor as
the Unitholder of record as of the First Settlement Date. Consequently, the
amount of accrued interest to be added to the Public Offering Price of Units
will include only accrued interest from the First Settlement Date to the date
of settlement (other than the Purchased Interest already included therein),
less any distributions from the Interest Account subsequent to the First
Settlement Date. See "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 Purchased Interest and accrued interest from
the purchaser of his Units. Since the Trustee has the use of the funds
(including Purchased Interest) held in the Interest Account for distributions
to Unitholders and since such Account is non-interest-bearing to Unitholders,
the Trustee benefits thereby. 

PUBLIC OFFERING 
   
General. Units are offered at the Public Offering Price which includes
Purchased Interest. During the initial offering period the Public Offering
Price is based on the offering prices of the Securities in each Trust and
includes a sales charge of 4.9% of the Public Offering Price (excluding
Purchased Interest) (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 (excluding
Purchased Interest) (4.493% of the aggregate offering price of the Securities)
for an IM-IT Limited Maturity Trust, 3.9% of the Public Offering Price
(excluding Purchased Interest) (4.058% of the aggregate offering price of the
Securities) for an IM-IT Intermediate Trust and 3.0% of the Public Offering
Price (excluding Purchased Interest) (3.093% of the aggregate offering price
of the Securities) for an IM-IT Short Intermediate Trust. After the initial
public offering period, the secondary market Public Offering Price is based on
the bid prices of the Securities in each Trust and includes a sales charge
determined in accordance with the table set forth below, which is based upon
the dollar weighted average maturity of each Trust plus in each case Purchased
Interest 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 funds or securities have been placed in
escrow to redeem them on an earlier call date, in which case such call date
will be deemed to be the date upon which they mature; or (b) such Bonds are
subject to a "mandatory tender", in which case such mandatory tender
will be deemed to be the date upon which they mature. 
    
The effect of this method of sales charge computation will be that different
sales charge rates will be applied to each Trust based upon the dollar
weighted average maturity of such Trust's Portfolio, in accordance with the
following schedule: 

<TABLE>

</TABLE>

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 (excluding Purchased Interest), the sales charge on
a Trust consisting entirely of a portfolio of Bonds with 15 years to maturity
would be 5.10%. The 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:

1,000 or more Units... $   19.00              $   11.00  
</TABLE>
    
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 Merritt-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 Merritt Inc. and its subsidiaries
may purchase Units of the Trust 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 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. 

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 plus Purchased Interest 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 (excluding Purchased Interest). 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 Services, Inc., 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 plus Purchased Interest 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 (excluding Purchased Interest). 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 Purchased Interest and 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 Purchased
Interest and 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 five 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 five 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
and the amount of Purchased Interest for 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 Purchased Interest 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 Purchased Interest and 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 Purchased Interest and/or 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 fifteenth 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. 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 record date, and distributions to the
Unitholders as of such record date will be made on or shortly after the
fifteenth day of such month. 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. 

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. 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, without interest, 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. 

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 Merritt Inc. (except Unitholders of a New York IM-IT Trust or a New
York IM-IT Intermediate Laddered Maturity Trust), may elect to have each
distribution of interest income, capital gains and/or principal on their Units
automatically reinvested in shares of any of the open ended mutual funds
(except for B shares) listed under "Trust Administration--Sponsor"
which are registered in the Unitholder's state of residence. New York IM-IT
Trust and New York IM-IT Intermediate Laddered Maturity Trust Unitholders,
other than those residing in the Commonwealth of Massachusetts, may elect to
have each distribution of interest income, capital gains and/or principal on
their Units automatically reinvested in shares of First Investors New York
Insured Tax Free Fund, Inc., a fund which invests primarily in securities
exempt from federal and New York state and city income tax. 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
Merritt Inc. at One Parkview Plaza, Oakbrook Terrace, Illinois 60181. Texas
residents who desire to reinvest may request that a broker-dealer registered
in Texas send the prospectus relating to the respective fund. 

After becoming a participant in a reinvestment plan, each distribution of
interest income, capital gains and/or principal on the participant's Units
will, on the applicable distribution date, automatically be applied, as
directed by such person, as of such distribution date by the Trustee to
purchase shares (or fractions thereof) of the applicable Reinvestment Fund at
a net asset value as computed as of the close of trading on the New York Stock
Exchange on such date, plus a sales charge of $1.00 per $100 of reinvestment
except if the participant selects the First Investors New York Insured Tax
Free Fund, Inc., in which case the sales charge will be $1.50 per $100 of
reinvestment, or except if the participant selects the Van Kampen Merritt
Money Market Fund or the Van Kampen Merritt Tax Free Money Fund in which case
no sales charge applies. A minimum of one-half of such sales charge would be
paid to Van Kampen Merritt Inc. for all Reinvestment Funds except First
Investors New York Insured Tax Free Fund, Inc., in which case such sales
charge would be paid to First Investors Management Company, Inc. 

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

A participant may at any time prior to five days preceding the next succeeding
distribution date, by so notifying the Trustee in writing, elect to terminate
his or her reinvestment plan and receive future distributions 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. 

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

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

Purchased Interest and 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 and Purchased Interest 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 and Purchased Interest 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) Purchased Interest for each Trust and (iv)
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, the amount of
Purchased Interest, 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. 

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".

outstanding exposure. 

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

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

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

The above ratings are not recommendations to buy, sell or hold the Bonds, and
such ratings may be subject to revision or withdrawal at any time by the
rating agencies. Any downward revision or withdrawal of either or both ratings
may have an adverse effect on the market price of the Bonds.

of a guaranty of scheduled payments of an issuer's securities, thereby
enhancing the credit rating of those securities, in consideration for payment
of a premium to the insurer. 

Financial Security is approximately 91.6% owned by U S WEST, Inc. and 8.4%
owned by The Tokio Marine and Fire Insurance Co., Ltd. ("Tokio Marine"
). Neither U S WEST, Inc. nor Tokio Marine is obligated to pay the debts of or
the claims against Financial Security. Financial Security is domiciled in the
State of New York and is subject to regulation by the State of New York
Insurance Department. As of March 31, 1993, the total policyholders' surplus
and contingency reserves and the total unearned premium reserve, respectively,
of Financial Security and its consolidated subsidiaries were, in accordance
with generally accepted accounting principles, approximately $479,110,000
(unaudited) and $220,078,000 (unaudited), and the total shareholders' equity
and the total unearned premium reserve, respectively, of Financial Security
and its consolidated subsidiaries were, in accordance with generally accepted
accounting principles, approximately $628,119,000 (unaudited) and $202,493,000
(unaudited). Copies of Financial Security's financial statements may be
obtained by writing to Financial Security at 350 Park Avenue, New York, New
York, 10022, Attention: Communications Department. Its telephone number is
(212) 826-0100. 

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

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

Capital Guaranty Insurance Company ("Capital Guaranty") is a "
Aaa/AAA"rated monoline stock insurance company incorporated in the State
of Maryland, and is a wholly owned subsidiary of Capital Guaranty Corporation,
a Maryland insurance holding company. Capital Guaranty Corporation is a
publicly owned company whose shares are traded on the New York Stock Exchange. 

Capital Guaranty is authorized to provide insurance in 49 states, the District
of Columbia and three U.S. territories. Capital Guaranty focuses on insuring
municipal securities and our policies guaranty the timely payment of principal
and interest when due for payment on new issue and secondary market issue
municipal bond transactions. Capital Guaranty's claims-paying ability is
rated "Triple-A"by both Moody's and Standard & Poor's.

     As of June 30, 1994, Capital Guaranty had more than $13.7 billion in net
exposure outstanding (excluding deferred issues). The total statutory
policyholders' surplus and contingency reserve of Capital Guaranty was
$89,917,075 (unaudited), and the total admitted assets were $286,825,253
(unaudited) as reported to the Insurance Department of the State of Maryland
as of June 30, 1994. Financial statements for Capital Guaranty Insurance
Company, that have been prepared in accordance with statutory insurance
accounting standards, are available upon request. The address of Capital
Guaranty's headquarters and its telephone number are Steuart Tower, 22nd
Floor, One Market Plaza, San Francisco, CA 94105-1413 and (415) 995-8000. 

CapMAC is a New York-domiciled monoline stock insurance company which engages
only in the business of financial guarantee and surety insurance. CapMAC is
licensed in 50 states in addition to the District of Columbia, the
Commonwealth of Puerto Rico and the territory of Guam. CapMAC insures
structured asset-backed, corporate, municipal and other financial obligations
in the domestic and foreign capital markets. CapMAC may also provide financial
guarantee reinsurance for structured asset-backed, corporate and municipal
obligations written by other major insurance companies. 

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

CapMAC is wholly owned by CapMAC Holdings Inc. ("Holdings"), a company
that is owned by a group of institutional and other investors, including
CapMAC's management and employees.

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

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

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

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

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

     As of December 31, 1993 and 1992, CapMAC had qualified statutory capital
(which consists of policyholders' surplus and contingency reserve) of
approximately $168 million and $163 million, respectively, and had not
incurred any debt obligations. Article 69 of the New York State Insurance Law
requires CapMAC to establish and maintain the contingency reserve, which is
available to cover claims under surety bonds issued by CapMAC.

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

CapMAC also has available a $100,000,000 standby corporate liquidity facility
(the "Liquidity Facility") provided by a syndicate of banks rated
A1+/P1 by Standard & Poor's and Moody's, respectively, having a term of 360
days. Under the Liquidity Facility CapMAC will be able, subject to satisfying
certain conditions, to borrow funds from time to time in order to enable it to
fund any claim payments or payments made in settlement or mitigation of claims
payments under its surety bonds, including the Surety Bond. 

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

In order to be in 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 Corporation has assigned to the Units of each Insured Trust
its "AAA"investment rating. 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
Corporation 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 Missouri IM-IT Trust was 5.54% after payment of the insurance premium
or premiums payable by such Trust, while the Estimated Long-Term Return on
such Trust was 5.66%. The Estimated Current Return on an identical portfolio
without the insurance obtained by the above-mentioned Trust would have been
5.56% 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 5.68%. 

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 Corporation "
AAA"rating and yet at the same time to have the protection of insurance
of prompt payment of interest and principal, when due, on the Bonds. There is,
of course, no certainty that this result will be achieved. Preinsured Bonds in
an Insured Trust (all of which are rated "AAA"by Standard & Poor's
Corporation) may or may not have a higher yield than uninsured bonds rated
"AAA"by Standard & Poor's Corporation. In selecting such Bonds for 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. One of the Bonds in
the IM-IT 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 located in 9 states or
territories, divided by purpose of issues (and percentage of principal amount
to total IM-IT) as follows: Health Care, 3 (19%); Industrial Revenue, 2 (16%);
Certificates of Participation, 1 (11%); Public Building, 1 (11%); Public
Education, 1 (11%); Tax District, 1 (11%); Wholesale Electric, 1 (11%); Retail
Electric/Gas, 1 (9%) and General Obligations, 1 (1%). Three bond issues
aggregating approximately 25% of the aggregate principal amount of the
securities in the Trust are obligations of issuers located in the State of
Illinois. No Bond issue has received a provisional rating. The dollar weighted
average maturity of the Bonds in the Trust is 27 years. 

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

<F1>During the first year the Trustee will reduce its fee by approximately $.16
per Unit (which amount is the estimated interest to be earned per Unit prior
to the expected delivery dates for the "when, as and if issued"Bonds
included in this Trust). Should such estimated interest exceed such amount,
the Trustee will reduce its fee up to its annual fee. After the first year,
the Trustee's fee will be that amount indicated above. Estimated annual
interest income per Unit will be increased to $60.07. Estimated Annual Expense
per Unit (excluding insurance) will be increased to $1.85; and estimated net
annual interest income per Unit will remain the same as shown. See "
Estimated Current Returns and Estimated Long-Term Returns."Based on the
outstanding principal amount of Securities as of the Date of Deposit, the
Trustee's annual fee would be $8,923. 

<F2>Excluding insurance costs. 

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

<F4>The 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 and with changes in the Purchased Interest; therefore, there is no
assurance that the present Estimated Current Return indicated above will be
realized in the future. The 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 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 Return as indicated above will be realized in the future. The
Estimated Current Return and Estimated Long-Term Return 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".

MICHIGAN IM-IT TRUST 

General. The Michigan IM-IT Trust consists of 8 issues of Securities. Four of
the Bonds in the Michigan IM-IT Trust 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 divided by purpose of issues (and percentage of principal amount to
total Michigan IM-IT Trust) as follows: General Obligations, 4 (48%);
Industrial Revenue, 1 (17%); Transportation, 1 (16%); Water and Sewer, 1 (16%)
and Health Care, 1 (3%). No Bond issue has received a provisional rating. 

Risk Factors. Investors should be aware that the economy of the State of
Michigan has, in the past, proven to be cyclical, due primarily to the fact
that the leading sector of the State's economy is the manufacturing of durable
goods. While the State's efforts to diversify its economy have proven
successful, as reflected by the fact that the share of employment in the State
in the durable goods sector has fallen from 33.1 percent in 1960 to 17.9
percent in 1990, durable goods manufacturing still represents a sizable
portion of the State's economy. As a result, any substantial national economic
downturn is likely to have an adverse effect on the economy of the State and
on the revenues of the State and some of its local governmental units. 

In May 1986, Moody's Investors Service raised the State's general obligation
bond rating to "A1". In October 1989, Standard & Poor's Corporation
raised its rating on the State's general obligation bonds to "AA". 

The State's economy could continue to be affected by changes in the auto
industry, notably consolidation and plant closings resulting from competitive
pressures and over-capacity. Such actions could adversely affect State
revenues and the financial impact on the local units of government in the
areas in which plants are closed could be more severe. 

General Motors Corporation has announced the scheduled closing of several of
its plants in Michigan in 1993 and 1994. The impact these closures will have
on the State's revenues and expenditures is not currently known. The impact on
the financial condition of the municipalities in which the plants are located
may be more severe than the impact on the State itself. 

In recent years, the State has reported its financial results in accordance
with generally accepted accounting principles. For each of the five fiscal
years ending with the fiscal year ended September 30, 1989, the State reported
positive year-end General Fund balances and positive cash balances in the
combined General Fund/School Aid Fund. For the fiscal years ending September
30, 1990 and 1991, the State reported negative year-end General Fund Balances
of $310.4 million and $169.4 million, respectively, but ended the 1992 fiscal
year with its general fund in balance and ended the 1993 fiscal year with a
small general fund surplus. A positive cash balance in the combined General
Fund/School Aid Fund was recorded at September 30, 1990. In the 1991 through
1993 fiscal years the State experienced deteriorating cash balances which
necessitated short term borrowing and the deferral of certain scheduled cash
payments. The State borrowed $900 million for cash flow purposes in the 1993
fiscal year, which was repaid on September 30, 1993. The State's Budget
Stabilization Fund received a $283 million transfer from the General Fund in
the 1993 State fiscal year, bringing the fund balance to $303 million at
September 30, 1993. 

The Michigan Constitution of 1963 limits the amount of total revenues of the
State raised from taxes and certain other sources to a level for each fiscal
year equal to a percentage of the State's personal income for the prior
calendar year. In the event that the State's total revenues exceeds the limit
by 1 percent or more, the Michigan Constitution of 1963 requires that the
excess be refunded to taxpayers. 

On March 15, 1994, Michigan voters approved a school finance reform amendment
to the State's Constitution which, among other things, increases the State
sales tax rate from 4% to 6% and places a cap on property assessment increases
for all property taxes. Such approval triggers the effectiveness of
legislation under which the State's income tax rate will be cut from 4.6% to
4.4%, some property taxes will be reduced and school funding will be provided
from a combination of property taxes and state revenues, some of which will be
provided from other new or increased State taxes. The legislation also
contains other proposals that may reduce or alter the revenues of local units
of government, and tax increment bonds could be particularly affected. While
the ultimate impact of the constitutional amendment and related legislation
cannot yet be accurately predicted, investors should be alert to the potential
effect of such measures upon the operations and revenues of Michigan local
units of government. 

Although all or most of the Bonds in the Michigan IM-IT Trust are revenue
obligations or general obligations of local governments or authorities rather
than general obligations of the State of Michigan itself, there can be no
assurance that any financial difficulties the State may experience will not
adversely affect the market value or marketability of the Bonds or the ability
of the respective obligors to pay interest on or principal of the Bonds,
particularly in view of the dependency of local governments and other
authorities upon State aid and reimbursement programs and, in the case of
bonds issued by the State Building Authority, the dependency of the State
Building Authority on the receipt of rental payments from the State to meet
debt service requirements upon such bonds. In the 1991 fiscal year, the State
deferred certain scheduled cash payments to municipalities, school districts,
universities and community colleges. While such deferrals were made up at
specified later dates, similar future deferrals could have an adverse impact
on the cash position of some local governmental units. Additionally, the State
reduced revenue sharing payments to municipalities below that level provided
under formulas by $10.9 million in the 1991 fiscal year, up $34.4 million in
the 1992 fiscal year, $45.5 million in the 1993 fiscal year and $64.6 million
(budgeted) in the 1994 fiscal year. 

The Michigan IM-IT Trust may contain general obligation bonds of local units
of government pledging the full faith and credit of the local unit which are
payable from the levy of ad valorem taxes on taxable property within the
jurisdiction of the local unit. Such bonds issued prior to December 22, 1978,
or issued after December 22, 1978 with the approval of the electors of the
local unit, are payable from property taxes levied without limitation as to
rate or amount. With respect to bonds issued after December 22, 1978, and
which were not approved by the electors of the local unit, the tax levy of the
local unit for debt service purposes is subject to constitutional, statutory
and charter tax rate limitations. In addition, several major industrial
corporations have instituted challenges of their ad valorem property tax
assessments in a number of local municipal units in the State. If successful,
such challenges could have an adverse impact on the ad valorem tax bases of
such units which could adversely affect their ability to raise funds for
operation and debt service requirements. 

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

In the opinion of Miller, Canfield, Paddock and Stone, special counsel to the
Fund for Michigan tax matters, under existing Michigan law: 

The Michigan IM-IT Trust and the owners of Units will be treated for purposes
of the Michigan income tax laws and the Single Business Tax in substantially
the same manner as they are for purposes of the Federal income tax laws, as
currently enacted. Accordingly, we have relied upon the opinion of Messrs.
Chapman and Cutler as to the applicability of Federal income tax under the
Internal Revenue Code of 1986 to the Michigan IM-IT Trust and the Holders of
Units. 

Under the income tax laws of the State of Michigan, the Michigan IM-IT Trust
is not an association taxable as a corporation; the income of the Michigan
IM-IT Trust will be treated as the income of the Unitholders and be deemed to
have been received by them when received by the Michigan IM-IT Trust. Interest
on the underlying Bonds which is exempt from tax under these laws when
received by Michigan IM-IT Trust will retain its status as tax exempt interest
to the Unitholders. 

For purposes of the foregoing Michigan tax laws, each Unitholder will be
considered to have received his pro rata share of Bond interest when it is
received by the Michigan IM-IT Trust, and each Unitholder will have a taxable
event when the Michigan IM-IT Trust disposes of a Bond (whether by sale,
exchange, redemption or payment at maturity) or when the Unitholder redeems or
sells his Certificate to the extent the transaction constitutes a taxable
event for Federal income tax purposes. The tax cost of each unit to a
Unitholder will be established and allocated for purposes of these Michigan
tax laws in the same manner as such cost is established and allocated for
Federal income tax purposes. 

Under the Michigan Intangibles Tax, the Michigan IM-IT Trust is not taxable
and the pro rata ownership of the underlying Bonds, as well as the interest
thereon, will be exempt to the Unitholders to the extent the Michigan IM-IT
Trust consists of obligations of the State of Michigan or its political
subdivisions or municipalities, or of obligations of possessions of the United
States. 

The Michigan Single Business Tax replaced the tax on corporate and financial
institution income under the Michigan Income Tax, and the Intangible Tax with
respect to those intangibles of persons subject to the Single Business Tax the
income from which would be considered in computing the Single Business Tax.
Persons are subject to the Single Business Tax only if they are engaged in
"business activity", as defined in the Act. Under the Single Business
Tax, both interest received by the Michigan IM-IT Trust on the underlying
Bonds and any amount distributed from the Michigan IM-IT Trust to a
Unitholder, if not included in determining taxable income for Federal income
tax purposes, is also not included in the adjusted tax base upon which the
Single Business Tax is computed, of either the Michigan IM-IT Trust or the
Unitholders. If the Michigan IM-IT Trust or the Unitholders have a taxable
event for Federal income tax purposes when the Michigan IM-IT Trust disposes
of a Bond (whether by sale, exchange, redemption or payment at maturity) or
the Unitholder redeems or sells his Certificate, an amount equal to any gain
realized from such taxable event which was included in the computation of
taxable income for Federal income tax purposes (plus an amount equal to any
capital gain of an individual realized in connection with such event but
excluded in computing that individual's Federal taxable income) will be
included in the tax base against which, after allocation, apportionment and
other adjustments, the Single Business Tax is computed. The tax base will be
reduced by an amount equal to any capital loss realized from such a taxable
event, whether or not the capital loss was deducted in computing Federal
taxable income in the year the loss occurred. Unitholders should consult their
tax advisor as to their status under Michigan law. 

Any proceeds paid under an insurance policy issued to the Trustee of the
Trust, or paid under individual policies obtained by issuers of Bonds, which,
when received by the Unitholders, represent maturing interest on defaulted
obligations held by the Trustee, will be excludable from the Michigan income
tax laws and the Single Business Tax if, and to the same extent as, such
interest would have been so excludable if paid by the issuer of the defaulted
obligations. While treatment under the Michigan Intangibles Tax is not
premised upon the characterization of such proceeds under the Internal Revenue
Code, the Michigan Department of Treasury should adopt the same approach as
under the Michigan income tax laws and the Single Business Tax. 

As the Tax Reform Act of 1986 eliminates the capital gain deduction for tax
years beginning after December 31, 1986, the federal adjusted gross income,
the computation base for the Michigan Income Tax, of a Unitholder will be
increased accordingly to the extent such capital gains are realized when the
Michigan IM-IT Trust disposes of a Bond or when the Unitholder redeems or
sells a Unit, to the extent such transaction constitutes a taxable event for
Federal income tax purposes.

<F1>Excluding insurance costs. 

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

<F3>The 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 and with changes in the Purchased Interest; therefore, there is no
assurance that the present Estimated Current Return indicated above will be
realized in the future. The 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 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 Return as indicated above will be realized in the future. The
Estimated Current Return and Estimated Long-Term Return 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".

MISSOURI IM-IT TRUST 

General. The Missouri IM-IT Trust consists of 9 issues of Securities. One of
the Bonds in the Missouri 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 Missouri IM-IT Trust) as follows: Health Care, 2 (32%); Higher
Education, 2 (26%); Water and Sewer, 1 (16%); Wholesale Electric, 1 (13%);
General Obligations, 1 (6%); Public Education, 1 (6%) and Escrowed to
Maturity, 1 (1%). No Bond issue has received a provisional rating. 

Risk Factors. The following discussion regarding constitutional limitations
and the economy of the State of Missouri is included for the purpose of
providing general information that may or may not affect issuers of the Bonds
in Missouri. 

In November 1981, the voters of Missouri adopted a tax limitation amendment to
the constitution of the State of Missouri (the "Amendment"). The
Amendment prohibits increases in local taxes, licenses, or fees by political
subdivisions without approval of the voters of such political subdivision. The
Amendment also limits the growth in revenues and expenditures of the State to
the rate of growth in the total personal income of the citizens of Missouri.
The limitation may be exceeded if the General Assembly declares an emergency
by a two-thirds vote. The Amendment did not limit revenue growth at the state
level in fiscal 1982 through 1988 with the exception of fiscal 1984.
Management Report No. 85-20, which was issued on March 5, 1985 by State
Auditor Margaret Kelly, indicates that state revenues exceeded the allowable
increase by $30.52 million in fiscal 1984, and a taxpayer lawsuit has been
filed pursuant to the Amendment seeking a refund of the revenues in excess of
the limit. 

The economy of Missouri is diverse and includes manufacturing, retail and
wholesale trade, services, agriculture, tourism and mining. In recent years,
growth in the wholesale and retail trade had offset the more slowly growing
manufacturing and agricultural sectors of the economy. In 1991, the
unemployment rate in Missouri was 6.6%, and according to preliminary
seasonally adjusted figures, the rate dropped to 5.4% in December 1992. There
can be no assurance that the general economic conditions or the financial
circumstances of Missouri or its political subdivisions will not adversely
affect the market value of the Bonds or the ability of the obligor to pay debt
service on such Bonds. 

Currently, Moody's Investors Service rates Missouri general obligation bonds
"Aaa"and Standard & Poor's Corporation rates Missouri general
obligation bonds "AAA". Although these ratings indicate that the State
of Missouri is in relatively good economic health, there can be, of course, no
assurance that this will continue or that particular bond issues may not be
adversely affected by changes in the State or local economic or political
conditions. 

The foregoing information constitutes only a brief summary of some of the
general factors which may impact certain issuers of Bonds and does not purport
to be a complete or exhaustive description of all adverse conditions to which
the issuers of obligations held by the Missouri IM-IT Trust are subject.
Additionally, many factors including national economic, social and
environmental policies and conditions, which are not within the control of the
issuers of the 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. The Sponsor is unable to predict whether or
to what extent such factors or other factors may affect the issuers of the
Bonds, the market value or marketability of the Bonds or the ability of the
respective issuers of the Bonds acquired by the Missouri 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
Missouri IM-IT Trust Units, see "Other Matters--Federal Tax Status". 

The assets of the Missouri IM-IT Trust will consist of debt obligations issued
by or on behalf of the State of Missouri (the "State") or counties,
municipalities, authorities or political subdivisions thereof (the "
Missouri Bonds") or by the Commonwealth of Puerto Rico, Guam and the
United States Virgin Islands (the "Possession Bonds") (collectively,
the "Bonds"). 

Neither the Sponsor nor its counsel have independently examined the Bonds to
be deposited in and held in the Missouri IM-IT Trust. However, although no
opinion is expressed herein regarding such matters, it is assumed that: (i)
the Bonds were validly issued, (ii) the interest thereon is excludable from
gross income for Federal income tax purposes and (iii) interest on the
Missouri Bonds, if received directly by a Unitholder, would be exempt from the
Missouri income tax applicable to individuals and corporations ("Missouri
state income tax"). The opinion set forth below does not address the
taxation of persons other than full time residents of Missouri. 

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

(1)   The Missouri IM-IT Trust is not an association taxable as a corporation
for Missouri income tax purposes, and each Unitholder of the Missouri IM-IT
Trust will be treated as the owner of a pro rata portion of the Missouri IM-IT
Trust and the income of such portion of the Missouri IM-IT Trust will be
treated as the income of the Unitholder for Missouri state income tax
purposes. 

(2)   Interest paid and original issue discount, if any, on the Bonds which
would be exempt from the Missouri state income tax if received directly by a
Unitholder will be exempt from the Missouri state income tax when received by
the Missouri IM-IT Trust and distributed to such Unitholder; however, no
opinion is expressed herein regarding taxation of interest paid and original
issue discount, if any, on the Bonds received by the Missouri IM-IT Trust and
distributed to Unitholders under any other tax imposed pursuant to Missouri
law, including but not limited to the franchise tax imposed on financial
institutions pursuant to Chapter 148 of the Missouri Statutes. 

(3)   To the extent that interest paid and original issue discount, if any,
derived from the Missouri IM-IT Trust by a Unitholder with respect to
Possession Bonds is excludable from gross income for Federal income tax
purposes pursuant to 48 U.S.C. (S)745, 48 U.S.C. (S)1423a, and 48 U.S.C.
(S)1403, such interest paid and original issue discount, if any, will not be
subject to the Missouri state income tax; however, no opinion is expressed
herein regarding taxation of interest paid and original issue discount, if
any, on the Bonds received by the Missouri IM-IT Trust and distributed to
Unitholders under any other tax imposed pursuant to Missouri law, including
but not limited to the franchise tax imposed on financial institutions
pursuant to Chapter 148 of the Missouri Statutes. 

(4)   Each Unitholder of the Missouri IM-IT Trust will recognize gain or loss
for Missouri state income tax purposes if the Trustee disposes of a bond
(whether by redemption, sale, or otherwise) or if the Unitholder redeems or
sells Units of the Missouri IM-IT Trust to the extent that such a transaction
results in a recognized gain or loss to such Unitholder for Federal income tax
purposes. Due to the amortization of bond premium and other basis adjustments
required by the Internal Revenue Code, a Unitholder under some circumstances,
may realize taxable gain when his or her Units are sold or redeemed for an
amount equal to their original cost. 

(5)   Any insurance proceeds paid under policies which represent maturing
interest on defaulted obligations which are excludable from gross income for
Federal income tax purposes will be excludable from the Missouri state income
tax to the same extent as such interest would have been paid by the issuer of
such Bonds held by the Missouri IM-IT Trust; however, no opinion is expressed
herein regarding taxation of interest paid and original issue discount, if
any, on the Bonds received by the Missouri IM-IT Trust and distributed to
Unitholders under any other tax imposed pursuant to Missouri law, including
but not limited to the franchise tax imposed on financial institutions
pursuant to Chapter 148 of the Missouri Statutes. 

(6)   The Missouri state income tax does not permit a deduction of interest
paid or incurred on indebtedness incurred or continued to purchase or carry
Units in the Trust, the interest on which is exempt from such Tax. 

(7)   The Missouri IM-IT Trust will not be subject to the Kansas City,
Missouri Earnings and Profits Tax and each Unitholder's share of income of the
Bonds held by the Missouri IM-IT Trust will not generally be subject to the
Kansas City, Missouri Earnings and Profits Tax or the City of St. Louis
Earnings Tax (except in the case of certain Unitholders, including
corporations, otherwise subject to the St. Louis City Earnings Tax).

<F1>Excluding insurance costs.

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

<F3>The 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 and with changes in the Purchased Interest; therefore, there is no
assurance that the present Estimated Current Return indicated above will be
realized in the future. The 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 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 Return as indicated above will be realized in the future. The
Estimated Current Return and Estimated Long-Term Return 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 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".

OKLAHOMA IM-IT TRUST 

General. The Oklahoma IM-IT Trust consists of 4 issues of Securities. One of
the Bonds in the Oklahoma 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 Oklahoma IM-IT Trust) as follows: Retail Electric/Gas, 1 (26%);
Transportation, 1 (26%); Wholesale Electric, 1 (26%) and General Obligations,
1 (22%). No Bond issue has received a provisional rating. 

Risk Factors. Investors in the Oklahoma IM-IT Trust should consider that the
economy of the State has been experiencing difficulties as a result of an
economic recession largely attributable to a decline in the agricultural
industry and a rapid decline that was experienced in the early and mid 1980s
in the energy industry which have, in turn, caused declines in the real estate
industry, the banking industry and most other sectors of the State's economy.
Continued low levels of economic activity, another decline in oil and gas
production prices, low growth in the State's major industries or private or
public financial difficulties could adversely affect Bonds in the Portfolio
and consequently the value of Units in the Oklahoma IM-IT Trust. 

Governmental expense budgeting provisions in Oklahoma are conservative,
basically requiring a balanced budget each fiscal year unless a debt is
approved by a vote of the people providing for the collection of a direct
annual tax to pay the debt. Certain limited exceptions include: deficiency
certificates issued in the discretion of the Governor (however, the deficiency
certificates may not exceed $500,000 in any fiscal year); and debts to repel
invasion, suppress insurrection or to defend the State in the event of war. 

To ensure a balanced annual budget, the State Constitution provides procedures
for certification by the State Board of Equalization of revenues received in
the previous fiscal year and amounts available for appropriation based on a
determination of revenues to be received by the State in the General Revenue
Fund in the next ensuing fiscal year. 

Beginning July 1, 1985, surplus funds were to be placed in a Constitutional
Reserve Fund until the Reserve Fund equals 10% of the General Revenue Fund
certification for the preceding fiscal year. 

The foregoing information constitutes only a brief summary of some of the
financial difficulties which may impact certain issuers of Bonds and does not
purport to be a complete or exhaustive description of all adverse conditions
to which the issuers in the Oklahoma IM-IT Trust are subject. Additionally,
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.
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 Oklahoma 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
Oklahoma IM-IT Trust Units, see "Other Matters--Federal Tax Status". 

The assets of the Oklahoma IM-IT Trust will consist of interest-bearing
obligations issued by or on behalf of the State of Oklahoma (the "
State") or counties, municipalities, authorities or political subdivisions
thereof (the "Oklahoma Bonds") or by the Commonwealth of Puerto Rico,
Guam and the United States Virgin Islands (the "Possession Bonds")
(collectively, the "Bonds"). At the respective times of issuance of
the Oklahoma Bonds, certain, but not necessarily all, of the issues of the
Oklahoma Bonds may have been accompanied by an opinion of bond counsel to the
respective issuing authorities that interest on such Oklahoma Bonds (the "
Oklahoma Tax-Exempt Bonds") are exempt from the income tax imposed by the
State of Oklahoma that is applicable to individuals and corporations (the "
Oklahoma State Income Tax"). The Trust may include Oklahoma Bonds the
interest on which is subject to the Oklahoma State Income Tax (the "
Oklahoma Taxable Bonds"). See "Portfolio"which indicates by
footnote which Oklahoma Bonds are Oklahoma Tax-Exempt Bonds (all other
Oklahoma Bonds included in the portfolio are Oklahoma Taxable Bonds). 

Neither the Sponsor nor its counsel has independently examined the Bonds to be
deposited in and held in the Trust. However, although no opinion is expressed
herein regarding such matters, it is assumed that: (i) the Bonds were validly
issued, (ii) the interest thereon is excludable from gross income for Federal
income tax purposes and (iii) interest on the Oklahoma Tax-Exempt Bonds, if
received directly by a Unitholder, would be exempt from the Oklahoma State
Income Tax. At the respective times of issuance of the Bonds, opinions
relating to the validity thereof and to the exemption of interest thereon from
Federal income tax were rendered by bond counsel to the respective issuing
authorities. In addition, with respect to the Oklahoma Tax-Exempt Bonds, bond
counsel to the issuing authorities rendered opinions as to the exemption of
interest from the Oklahoma State Income Tax. Neither the Sponsor nor its
counsel has made any review for the Trust of the proceedings relating to the
issuance of the Bonds or of the bases for the opinions rendered in connection
therewith. The opinion set forth below does not address the taxation of
persons other than full time residents of Oklahoma. 

In the opinion of Chapman and Cutler, Special Counsel to the Fund for Oklahoma
tax matters, under existing laws as of the date of this Prospectus and based
upon the assumptions set forth above: 

(1) For Oklahoma State Income Tax purposes, the Trust is not an association
taxable as a corporation, each Unitholder of the Trust will be treated as the
owner of a pro rata portion of the Trust and the income of such portion of the
Trust will be treated as the income of the Unitholder. 

(2) Interest paid and original issue discount, if any, on the Bonds which
would be exempt from the Oklahoma State Income Tax if received directly by a
Unitholder will be exempt from the Oklahoma State Income Tax when received by
the Trust and distributed to such Unitholder. A Unitholder's pro rata portion
of any interest paid and original issue discount, if any, on the Bonds which
would be subject to the Oklahoma State Income Tax if received directly by a
Unitholder, including, for example interest paid and original issue discount,
if any, on the Oklahoma Taxable Bonds, will be taxable to such Unitholder for
Oklahoma State Income Tax purposes when received by the Trust. 

(3) To the extent that interest paid and original issue discount, if any,
derived from the Trust by a Unitholder with respect to Possession Bonds is
excludable from gross income for Federal income tax purposes pursuant to 48
U.S.C. (S)745, 48 U.S.C. (S)1423a, and 48 U.S.C. (S)1403, such interest paid
and original issue discount, if any, will not be subject to the Oklahoma State
Income Tax. 

(4) Each Unitholder of the Trust will recognize gain or loss for Oklahoma
State Income Tax purposes if the Trustee disposes of a Bond (whether by
redemption, sale, or otherwise) or if the Unitholder redeems or sells Units of
the Trust to the extent that such a transaction results in a recognized gain
or loss to such Unitholder for Federal income tax purposes. Due to the
amortization of bond premium and other basis adjustments required by the
Internal Revenue Code, a Unitholder, under some circumstances, may realize
taxable gain when his or her Units are sold or redeemed for an amount equal to
their original cost. 

(5) Although no opinion is expressed herein, we have been informally advised
by the Oklahoma Tax Commission that any insurance proceeds paid under policies
which represent maturing interest on defaulted obligations which are
excludable from gross income for Federal income tax purposes should be
excludable from the Oklahoma State Income Tax to the same extent as such
interest would have been if paid by the issuer of such Bonds held by the
Trust. 

(6) The Oklahoma State Income Tax does not permit a deduction of interest paid
or incurred on indebtedness incurred or continued to purchase or carry Units
in the Trust, the interest on which is exempt from such tax. 

(7) Although no opinion is expressed herein, we have been informally advised
by the Oklahoma Tax Commission that the Trust, in part because of its status
as a "grantor trust"for Federal income tax purposes, should not be
subject to the Oklahoma state franchise tax. 

The scope of this opinion is expressly limited to the matters set forth
herein, and we express no other opinions of law with respect to the state or
local taxation of the Trust, the purchase, ownership or disposition of Units
or the Unitholders under Oklahoma law.

<F1>Excluding insurance costs.

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

<F3>The 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 and with changes in the Purchased Interest; therefore, there is no
assurance that the present Estimated Current Return indicated above will be
realized in the future. The 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 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 Return as indicated above will be realized in the future. The
Estimated Current Return and Estimated Long-Term Return 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".

NOTES TO PORTFOLIOS:As of the Date of Deposit: September 20, 1994

(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
August 17,1994 to September 19,1994. These Securities have expected settlement
dates ranging from September 20,1994 to October 4,1994 (see "Unitholder
Explanations"). 
    
(2) All ratings are by Standard & Poor's
Corporation 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"). 

(5) Other information regarding the Bonds in each Trust, as of the Date of
Deposit, is as follows:

On the Date of Deposit, the offering side evaluations of the Securities in the
IM-IT, Michigan IM-IT, Missouri IM-IT and  Oklahoma IM-IT Trusts were higher
than the bid side evaluations of such Securities by 0.74%, 0.77%, 0.74% and
0.79%, 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. Approximately 1% and1% of the aggregate principal
amount of the Securities in the IM-IT and Missouri IM-IT Trusts, respectively,
are "zero coupon"bonds. 
    
Underwriting. The Underwriters named below have severally purchased Units in
the following respective amounts from the Sponsor.

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.

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 Merritt Investment
Advisory Corp., which is a wholly-owned subsidiary 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 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. The Trustee's fees are payable
monthly on or before the fifteenth 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 and (g) expenditures incurred in
contacting Unitholders upon termination of the Trusts. 

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 an IM-IT Limited Maturity, IM-IT
Intermediate and IM-IT Short Intermediate Trust. 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 Purchased Interest, plus
interest accrued but unpaid from the First Settlement Date to the date of
settlement as described above under "Unitholder Explanations--Purchased
and 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
Purchased Interest 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 $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". 

To facilitate the handling of transactions during the initial offering period,
sales of Units shall normally be limited to transactions involving a minimum
of five Units. Further purchases may be made in multiples of one Unit. The
minimum purchase in the secondary market will be one Unit. 

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 (excluding Purchased Interest) 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, $22.00 and $35.00 per Unit of any
IM-IT, IM-IT Limited Maturity, IM-IT Intermediate, IM-IT Short Intermediate
and other Insured Trust, 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 The Principal/Eppler, Guerin & Turner, 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 The Principal/Eppler,
Guerin & Turner, Inc. will receive an additional $1.00 per Unit for each of
the Units of such Trust it commits to underwrite in said month. In addition,
the Sponsor will receive from the Managing Underwriters of the Oklahoma IM-IT
Trust (who underwrite 15% of the Trust or 1,000 Units of such Trust, whichever
is greater) the excess of such gross sales commission over  $38.00 per Unit of
any such Trust, as of the Date of Deposit. Also, any such  Managing
Underwriter that sells a total of 25% or 1,500 Units, whichever is  greater,
of any Oklahoma IM-IT Trust will receive an additional $2.00 per each such
Unit. 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 Services, Inc. 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, Missouri and Oklahoma  tax law have been passed upon by
Chapman and Cutler, 111 West Monroe Street, Chicago, Illinois 60603, as
counsel for the Sponsor. Miller, Canfield, Paddock and Stone has acted as
special counsel to the Fund for Michigan tax matters.   Tanner Propp & Farber
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, 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, except
to the extent such interest is subject to the alternative minimum tax, an
additional tax on branches of foreign corporations and the environmental tax
(the "Superfund Tax"), as noted below; 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

DESCRIPTION OF SECURITIES RATINGS*

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

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

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

The ratings are based, in varying degrees, on the following considerations:

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. 

*As published by the rating companies.

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 Merritt Inc. and the Unitholders of
Insured Municipals Income Trust, 165th Insured Multi-Series (IM-IT, Michigan
IM-IT, Missouri IM-IT and Oklahoma IM-IT Trusts): 

We have audited the accompanying statements of condition and the related
portfolios of Insured Municipals Income Trust, 165th Insured Multi-Series
(IM-IT, Michigan IM-IT, Missouri IM-IT and Oklahoma IM-IT Trusts) as of
September 20, 1994. 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, 165th Insured Multi-Series (IM-IT, Michigan IM-IT, Missouri IM-IT and
Oklahoma IM-IT Trusts) as of September 20, 1994, in conformity with generally
accepted accounting principles.

<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>Accrued interest on the underlying Securities represents the interest accrued
as of the First Settlement Date from the later of the last payment date on the
Securities or the date of issuance thereof. The Trustee may advance to the
Trust a portion of the accrued interest on the underlying Securities for
distribution to the Sponsor as the Unitholder of record as of the First
Settlement Date. A portion of the accrued interest ("Purchased
Interest") on the underlying Securities, as indicated under "Summary
of Essential Financial Information", is payable by investors and is
included in the Public Offering Price. Purchased Interest is the difference
between Accrued interest to the First Settlement Date and Accrued interest
payable to Sponsor.
</TABLE>

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 1994. 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. For cases in which more than one
State bracket falls within a Federal bracket, the highest State bracket is
combined with the Federal bracket. The combined State and Federal tax rates
shown reflect the fact that State tax payments are currently deductible for
Federal tax purposes. 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 $111,800. The tables
do not reflect the effect of limitations on itemized deductions and the
deduction for personal exemptions. They 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.

*The combined State and Federal tax bracket is computed utilizing a 4.47%
state personal income tax rate which is a weighted average rate that takes
into account a change in tax rates which was recently approved by Michigan
voters and a 3.5% tax on intangible income. The bracket does not reflect the
effect of the exemption from local income taxes; accordingly, Michigan
residents subject to such local income taxes would need a somewhat higher
taxable estimated current return than those shown to equal the tax-exempt
estimated current return of the Trust.

*The combined State and Federal tax bracket is computed by taking into account
the deductibility of State tax in determining Federal tax and the recently
enacted limitations on the deductibility of Federal tax in determining State
tax.  Specifically, the deduction allowed for Federal income tax liability may
not exceed $5,000 and $10,000 for single and joint taxpayers respectively. 
Accordingly, the combined tax bracket reflects cross-deductibility of each tax
determining the other only for levels of income corresponding to the 15%
Federal tax bracket.

*The combined Federal and State tax rate provided for the Oklahoma IM-IT Trust
takes into account the fact that all of the annual income of the Trust
generated by the Bonds in the Oklahoma IM-IT Trust is exempt from the Oklahoma
state income tax. The table does not reflect the fact that Oklahoma taxpayers
have the option of not deducting Federal income tax liability for Oklahoma tax
purposes. If an Oklahoma taxpayer chooses this option, the taxpayer may be
taxed at a rate lower than the rate shown in the above table.
    

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
Merritt 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 distributions of interest,
principal and rebates of Purchased Interest 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.

    (a)   "Policy" is this policy of insurance and all applications and
schedules for Municipal Bond Investment Trust Insurance relating hereto,
all of which are hereby incorporated by reference herein.

    (b)   "Bonds" are the specific securities covered by this Policy and
are identified and described in the Schedule attached hereto and hereby
made a part hereof.

    (c)   "Issuer" is each respective issuer, identified in the Schedule,
of the Bonds.

    (d)   "Investment Trust" is the entity represented to have an
insurable interest in the Bonds insured under this Policy, identified on
the face of this Policy.

    (e)   "Trustee" is the Trustee of the Investment Trust, or any
successor Trustee thereto or Co-Trustee therewith.

    (f)   "Sponsor" is the firm or entity responsible for creating the
Investment Trust and thereafter performing the services to it required of
its sponsor, or any successor Sponsor thereof or Co-Sponsor therewith.

    (g)   "Insured Instrument" is any instrument evidencing all or any
part of the principal or of interest on a Bond which is Due for Payment.

    (h)   "Policy Period" is the period during which this Policy of
insurance is effective.  The Policy Period commences at 12:01 A.M.

     (i)    "Premium Installment Period" is the period for  which
installments of the annual insurance premium are payable monthly,
quarterly or semiannually, as determined initially for the Investment
Trust.

    (j)   "Nonpayment" is the failure of an Issuer to provide sufficient
funds to the payment agent for payment in full of all principal and
interest on a Bond which is Due for Payment.

    (k)   "Due for Payment," when referring to principal of a Bond (or
Insured Instrument evidencing such principal), is when the stated
maturity date has been reached, and does not refer to any earlier date on
which payment is due by reason of call for redemption, acceleration or
other advancement of maturity; and when referring to interest on a Bond
(or Insured Instrument evidencing such interest), is when the stated date
for payment has been reached.

    (l)   "Bond Proceedings" are the legal proceedings by which each of
the Bonds has been authorized, issued or secured, including the governing
statutes, the pertinent resolutions and ordinances of the Issuer, and any
trust indenture, mortgage, lease agreement or other contract relating to
the Bond or its security.


2.   Noncancellability and Termination-Refunds of Premium
     
     This Policy cannot be cancelled by AMBAC.  The insurance provided by
this Policy shall remain in force throughout the Policy period.  This
Policy provides for payment to the Trustee as a result of Nonpayment of
the Bonds.  In the event the Trustee sells any of the Bonds, then this
Policy shall be terminated as to any such Bond on the date of said sale,
and AMBAC shall not have any liability under t his Policy on account of
Nonpayment of any such Bond occurring thereafter.  This Policy shall be
terminated as to any Bond which AMBAC has been notified by the Sponsor or
by the Trustee has been redeemed from or sold by the Investment Trust, or
was not deposited by the Sponsor, or the contract to purchase which has
failed, on the date such notice is received by AMBAC, and AMBAC shall not
have any liability under this Policy on account of Nonpayment of any such
Bond occurring thereafter.  When AMBAC is notified by the Trustee or the
Sponsor that any of the Bonds have been redeemed or sold from the
Investment Trust, or were not deposited into it, or a contract to
purchase any such Bonds has failed, a refund of any prepaid premium
thereof shall be made to the Investment Trust or the Sponsor, as the case
may be.  Such notification to AMBAC must specify the amount of Bonds
affected, identify each by its Item Number in an Application identified
by its date and designate the date of such disposal or failure.


3.   payment by Insurer-Amount, When and How Payable

    (a)   Amount-Payment by AMBAC of the aggregate of the face amount of
all Insured Instruments of the Investment Trust as to which there has
been a Nonpayment, reduced by the aggregate of:  (i) the amount which the
Issuer shall have provided for payment of Insured Instruments by the time
of Nonpayment; and (ii) the amount which has been received from any other
source to pay Insured Instruments; such payment shall fully discharge
AMBAC from any further liability on account of the Nonpayment.

    (b)   When Payable-The payment due the Investment Trust shall be made
not later than thirty days after notice from the Trustee is received by
AMBAC that Nonpayment has occurred, but not earlier than the date on
which the Insured Instruments are Due for Payment.

    (c)   How Payable-The payment due the Investment Trust shall be paid
by AMBAC in exchange for delivery of Insured Instruments, not less in
face amount than the amount of the payment, in bearer form, free and
clear of all liens and encumbrances and uncancelled.  In cases where an
Insured Instrument is issuable only in a form whereby principal is
payable to registered holders or their assigns, AMBAC shall pay principal
only upon presentation and surrender of the unpaid Insured Instrument,
uncancelled and free of any adverse claim, together with an instrument of
assignment, in satisfactory form, so as to permit ownership of such
Insured Instrument to be registered in the name of AMBAC or its nominee.
In cases where an Insured Instrument is issuable only in a form whereby
interest is payable to registered holders or their assigns, AMBAC shall
pay interest only upon presentation of proof that the claimant is the
person entitled to the pa shall pay interest only upon presentation of
proof that the claimant is the person entitled to the payment of interest
on the Insured Instrument and delivery of an instrument of assignment, in
satisfactory form, transferring to AMBAC all rights under such Insured
Instrument to receive the interest in respect of which the insurance
payment was made.

4.   Rights of AMBAC

    (a)   Subrogation-When AMBAC has made payment with respect to an
Insured Instrument, it shall be subrogated to all of the rights to
payment of the Investment Trust thereon or in relation thereto to the
extent of such payment.

    (b)   Vesting of Rights and Powers-When AMBAC has made the payment
due to the Investment Trust as described in Condition 3, and until the
full amount of such payment has been recovered, AMBAC shall be vested
with all of the Investment Trust's options, votes, rights, powers and the
like under the Bond Proceedings.  AMBAC shall not be liable to the
Investment Trust for any loss or damage resulting from the exercise of or
failure to exercise any of such options, votes, rights, powers and the
like.

    (c)   Exercise of Rights and Powers-AMBAC may, in its absolute
discretion, exercise or fail to exercise any option, vote, right, power
or the like it may have as holder or registered owner of an Insured
Instrument with respect to which it has made payment.  AMBAC shall not be
liable to the Investment Trust for any loss or damage resulting therefrom

    (d)   Securing of Rights-The Trustee shall execute and deliver
instruments and do whatever else is necessary to secure the foregoing
rights for AMBAC, and will do nothing to prejudice them.

5.   Payment of Insurance Premium Installments
     
     The Trustee shall pay, when due, successively, the full amount of
each installment of the insurance premium.  Each installment of the
insurance premium is due on or before the last day of the expiring
Premium Installment Period.
     
     If AMBAC has not received such payment on or before such last day,
it shall give notice to the Sponsor to that effect.  Such installment
shall be deemed to have been paid when due if AMBAC receives such payment
within ten days after it has given such notice.
     
     The Trustee shall, with each payment, notify AMBAC of all Bonds
which, during the expiring Premium Installment period, were redeemed from
or sold by the Investment Trust, or the contract to purchase which
failed,  or  which have not been deposited by the Sponsor.   Such
notification to AMBAC must specify the amounts of Bonds affected and
identify each by its Item Number in an Application identified by date.
No such notice need be given as to Bonds with respect to which AMBAC has
previously been notified to the same effect.

6.   Where Notice is Given
     
     All submissions, designations, payments, notices, reports and other
data or documents required to be submitted shall be mailed to AMBAC at
its administrative office, or to the Investment Trust at its address
shown on the face of this Policy or such other address as it shall
designate.

7.   Waiver of Conditions
     
     No permission affecting this insurance shall exist, or waiver of any
condition be valid, unless expressed in writing added hereto.  Each of
the conditions of this Policy is hereby made severable, and waiver of one
condition is not a waiver of any other condition.

8.   Suit
     
     No suit or action on this Policy for the recovery of any amount
shall be sustained in any court of law or equity unless all of the
conditions  of this Policy shall have been complied with  (unless
specifically waived by AMBAC in writing) and unless commended within two
years after a Nonpayment.

9.   Conflict of Laws
     
     Any provision of this Policy which is on conflict with the laws of
the jurisdiction in which it is effective is hereby amended to conform
with the minimum requirements of such laws.

Van Kampen Merritt Inc.
One Parkview Plaza
Oakbrook Terrace, Illinois 60181

Gentlemen:

      1.    The  Trust.  We understand that you, Van Kampen Merritt  Inc.
(the  "Sponsor"), are entering into this agreement (the  "Agreement")  in
counterparts with us and other firms who may be underwriters  for  issues
of  various  series of unit investment trusts for which you will  act  as
Sponsor.  This Agreement shall apply to any offering after May 1, 1992 of
units  of  fractional  undivided interest in  such  various  series  unit
investment   trusts  in  which  we  elect  to  act  as   an   underwriter
(underwriters  with  respect to each such trust being hereinafter  called
"Underwriters") after receipt of a notice from you stating the  name  and
size  of  the trust and that our participation as an Underwriter  in  the
proposed  offering shall be subject to the provisions of this  Agreement.
The issuer of the units of fractional undivided interests in a series  of
a unit investment trust offered in any offering of units made pursuant to
this  Agreement  is  hereinafter referred  to  as  the  "Trust"  and  the
reference  to "Trust" in this Agreement applies only to such  Trust,  and
such  units  of  such Trust offered are hereinafter called  the  "Units".
Each  Trust  is or will be registered as a "unit investment trust"  under
the  Investment  Company  Act  of 1940 (the "1940  Act")  by  appropriate
filings  with  the Securities and Exchange Commission (the "Commission").
Additionally,  each  Trust is or will be registered with  the  Commission
under  the  Securities Act of 1933 (the "1933 Act") on Form  S-6  or  its
successor   forms,   including  a  proposed  form  of   prospectus   (the
"Preliminary Prospectus").
     
     The  registration statement as finally amended and  revised  at  the
time  it  becomes  effective is herein referred to as  the  "Registration
Statement"  and  the  related prospectus is herein  referred  to  as  the
"Prospectus",  except that if the prospectus filed by the Trust  pursuant
to  Rule  424(b) under the 1933 Act shall differ from the  prospectus  on
file  at the time the Registration Statement shall become effective,  the
term  "Prospectus" shall refer to the prospectus filed pursuant  to  Rule
424(b) from and after the date on which it shall have been filed.
     
     The following provisions of this Agreement shall apply separately to
each individual offering of Units by a Trust.
     
     We  understand  that as of the date upon which  we  have  agreed  to
underwrite  Units of the Trust the Commission shall not have  issued  any
order  preventing  or  restraining the use of any Preliminary  Prospectus
and,  further,  that  each Preliminary Prospectus shall  conform  in  all
material  respects to the requirements of the 1933 Act and the Rules  and
Regulations thereunder and, as of its date, shall not include any  untrue
statement  of a material fact or omit to state a material fact  necessary
to  make the statements therein not misleading; and when the Registration
Statement becomes effective, it and the Prospectus, and any amendments or
supplements thereto, will contain all statements that are required to  be
stated  therein  in  accordance with the  1933  Act  and  the  Rules  and
Regulations thereunder and will in all material respects conform  to  the
requirements  of  the 1933 Act and the Rules and Regulations  thereunder,
and  neither  the  Registration Statement nor  the  Prospectus,  nor  any
amendment or supplement thereto, will contain any untrue statement  of  a
material  fact  or omit to state a material fact required  to  be  stated
therein  or  necessary  to  make the statements therein  not  misleading;
provided,  however, that you make no representation  or  warranty  as  to
information contained in or omitted from any Preliminary Prospectus,  the
Registration   Statement,  the  Prospectus  or  any  such  amendment   or
supplement,  in reliance upon and in conformity with, written information
furnished to you by or on behalf of any Underwriter specifically for  use
in the preparation thereof.

      2.    Designation and Authority of Representative.  You are  hereby
authorized  to  act  as  our  representative  (the  "Representative")  in
connection with all matters to which this Agreement relates and  to  take
the  action provided herein to be taken by you as you may otherwise  deem
necessary or advisable.  We understand that we have no obligations  under
this  Agreement  with  respect to any Trust in which  we  choose  not  to
participate as an Underwriter.
     
     You  will be under no liability to us for any act or omission except
for  obligations  expressly assumed by you herein and no  obligations  on
your  part  will  be  implied  or  inferred  herefrom.   The  rights  and
liabilities of the respective parties hereto are several and  not  joint,
and  nothing  herein  or hereunder will constitute  then  a  partnership,
association or separate entity.

      3.   Profit or Loss in Acquisition of Securities.  It is understood
that the acquisition of securities (the "Securities") for deposit in  the
portfolio  of  the Trust shall be at your cost and risk.  We  acknowledge
that you will share with us any net deposit profits in the amounts and to
the   extent,   if   any,  indicated  under  "Sponsor   and   Underwriter
Compensation"  in  the Prospectus.  For the purposes of  determining  the
number of Units underwritten, we understand that we will be credited  for
that  number of Units set forth opposite our name in the section entitled
"Underwriting" in the prospectus.
     
     We  agree  that  you  shall have no liability (as Representative  or
otherwise)   with   respect  to  the  issue  form,  validity,   legality,
enforceability,  value  of, or title to the Securities,  except  for  the
exercise  of  due care in determining the genuineness of such  Securities
and  the  conformance  thereof with the descriptions  and  qualifications
appearing in the Prospectus.

      4.   Purchase of Units.  Promptly after you make a determination to
offer  Units  of  a  Trust and you inquire as to  whether  we  desire  to
participate  in  such offering, we will advise you  promptly  as  to  the
number  of  Units  which  we will purchase or  of  our  decision  not  to
participate in such offering.  Such advice may be written or  oral.   The
delivery to the Sponsor of a completed Schedule A to this Agreement shall
constitute  adequate written advice.  Oral advice shall  be  binding  but
shall  be  promptly  confirmed in writing by us by  means  of  telegraph,
telegram  or other form of wire or facsimile transmission.  Such  written
confirmation  shall contain the information requested by  Schedule  A  to
this  Agreement.  You may rely on and we hereby commit on the  terms  and
conditions of this Agreement to purchase and pay for the number of  Units
of  the Trust set forth in such advice (the "Unit Commitment").  Our Unit
Commitment may be increased only by mutual agreement between us  and  you
at  any  time prior to the date as of which the Trust Agreement  for  the
Trust  is  executed (the "Date of Deposit").  We agree that you  in  your
sole discretion reserve the right to decrease our Unit Commitment at  any
time  prior  to the Date of Deposit and if you so elect to  make  such  a
decrease,  you  will  notify  us of such an  election  by  telephone  and
promptly confirm the same in writing.
     
     The  price  to  be paid for such Units shall be the Public  Offering
Price per Unit (as defined in the Prospectus) as first determined on  the
Date  of  Deposit or such later determination on such Date of Deposit  as
you  shall advise us, less the sum per Unit indicated under "Sponsor  and
Underwriter  Compensation" in the Prospectus.  Further, each  Underwriter
who  underwrites  that  number  of Units  indicated  under  "Sponsor  and
Underwriter Compensation" in the Prospectus will receive from the Sponsor
that  additional  compensation  indicated  under  such  section  of   the
Prospectus for each Unit it underwrites, providing the Trust size  is  in
excess  of that number of Units, if any, indicated under such section  of
the  Prospectus.  At the Date of Deposit, we will become the owner of the
Units  and  be  entitled to the benefits (except for  interest,  if  any,
accruing from the Date of Deposit to the First Settlement Date)  as  well
as  the  risks inherent therein.  We acknowledge that those  persons,  if
any, named in the Prospectus under "Sponsor and Underwriter Compensation"
are  Managing  or  Co-Managing Underwriters of the  Trust,  as  indicated
therein, and we acknowledge that those persons specifically named therein
will receive as additional compensation those respective per Unit amounts
set forth in such section of the Prospectus.
     
     You  are  authorized  to  retain custody  of  our  Units  until  the
Registration  Statement relating thereto has become effective  under  the
1933 Act and you shall have received payment from us for such Units.
     
     You  are  authorized  to  file  an amendment  to  said  Registration
Statement  describing  the  Securities and furnishing  information  based
thereon or relating thereto and any further amendments or supplements  to
the Registration Statement or Prospectus which you may deem necessary  or
advisable.  We will furnish to you upon your request such information  as
will be required to insure that the Registration Statement and Prospectus
are  current  insofar as they relate to us and we thereafter continue  to
furnish you with such information as may be necessary to keep current and
correct the information previously supplied.
     
     We  understand that the Trust will also take action with respect  to
the  offering  and  sale of Units in accordance  with  the  Blue  Sky  or
securities laws of certain states in which it is proposed that the  Units
may be offered and sold.

      5.    Public Offering.  You agree that you will advise us  promptly
when  the Registration Statement has become effective, and we agree  that
when  we are advised that the Units are released for public offering,  we
will make a public offering thereof by means of the Prospectus under  the
1933  Act,  as  amended, which describes the deposit  of  Securities  and
related  information.   The  Public Offering  Price  and  the  terms  and
conditions of the public offering shall be as set forth in the Prospectus
and  shall rely with respect to the offering price of the Securities upon
the  determination  of  the Evaluator named in  the  Prospectus.   Public
advertisement of the offering, if any, shall be made by you on behalf  of
the  Underwriters  on such date as you shall determine.   We  agree  that
before  we  use any Trust advertising material which we have created,  we
will obtain your prior approval to use such advertising materials.

      6.    Public  Offering Price.  We agree that each  day  while  this
Agreement  is in effect and the evaluation of the Trust is  made  by  the
Evaluator  named  in  the  Prospectus,  we  will  contact  you  for  such
evaluation and of the resultant Public Offering Price for the purpose  of
the offering and sale of the respective Units to the public.  We agree as
required by Section 22(d) of the 1940 Act to offer and sell our Units  at
the current Public Offering Price described in the Prospectus.

      7.    Permitted Transactions.  It is agreed that part or all of the
Units purchased by us may be sold to dealers, or other entities with whom
we  can legally grant a concession or agency commission, only at the then
effective  Public  Offering Price, less the concession described  in  the
Prospectus.
     
     From  time  to  time prior to the termination of this Agreement,  at
your  Request, we will advise you of the number of our Units which remain
unsold  and,  at  your request, we agree to deliver to you  any  of  such
unsold  Units to be sold for our account to retail accounts or, less  the
concession or agency commission then effective, to dealers or others.
     
     If  prior to the termination of this Agreement, or such earlier date
as you may determine and advise us thereof in writing, you shall purchase
or  contract to purchase any of our Units or any Units issued in exchange
therefor, in the open market or otherwise, or if any such Units shall  be
tendered to the Trustee for redemption because not effectively placed for
investment by us, we agree to repurchase such Units at a price  equal  to
the   total  cost  of  such  purchase,  including  accrued  interest  and
commissions, if any, and transfer taxes on redelivery.  Regardless of the
amount  paid on the repurchase of any such Units, it is agreed that  they
may be resold by us only at the then effective Public Offering Price.
     
     Until the termination of this Agreement, we agree that we will  make
no  purchase  of  Units  other than (i) purchases provided  for  in  this
Agreement, (ii) purchases approved by you and (iii) purchases  as  broker
in executing unsolicited orders.

      8.   Compliance With Commission Order.  We hereby agree as follows:
(a)  we will refund all sales charges to purchasers of Units from  us  or
any  dealer participating in the distribution of Units who purchased such
Units  from us if, within ninety days from the time that the Registration
Statement  of the respective Units under the 1933 Act shall  have  become
effective, (i) the net worth of the trust shall be reduced to  less  than
20% of the principal amount of Securities originally deposited therein or
(ii)  the  Trust  shall have been terminated; (b) you  may  instruct  the
Trustee on the Date of Deposit that, in the event that redemption by  any
Underwriters of Units constituting part of any unsold allotment of  Units
shall  result  in the Trust having a net worth of less than  40%  of  the
principal amount of Securities originally deposited therein, the  Trustee
shall  terminate the Trust in the manner provided in the Trust  Indenture
and   Agreement  (as  defined  in  the  Prospectus)  and  distribute  the
Securities  and other assets of the Trust pursuant to the  provisions  of
the  Trust  Indenture and Agreement; and (c) in the event that the  Trust
shall  have  been  terminated pursuant to (b) above, we will  refund  any
sales  charges to any purchaser of such Units who purchased from  us,  or
purchased  from a dealer participating in the distribution of such  Units
who purchased such Units from us.  We authorize you to charge our account
for all refunds of sales charges in respect to our Units.

      9.   Substitution of Underwriters.  We authorize you to arrange for
the  substitution hereunder of other persons, who may include you and us,
for  all  or  any part of the commitment of any nondefaulting Underwriter
with  the  consent of such Underwriter, and of any defaulting Underwriter
without  the consent thereof, upon such terms and conditions as  you  may
deem  advisable, provided that the number of Units to be purchased by  us
shall  not  be  increased without our consent and that such  substitution
shall  not  in any way affect the liability of any defaulting Underwriter
to  the other Underwriters for damages from such default, nor relieve any
other  Underwriter of any obligation under this Agreement.  The  expenses
chargeable to the account of any defaulting Underwriter and not paid  for
by  it or by a person substituted for such Underwriter and any additional
losses  or expenses arising from such default shall be considered  to  be
expenses  under this Agreement and shall be charged against the  accounts
of  the  nondefaulting  Underwriters in proportion  to  their  respective
commitments.

     10.    Termination.  This Agreement shall terminate with respect  to
each  Trust which we have agreed to underwrite 30 days after the date  on

accordance  with  Section  5  hereof unless  sooner  terminated  by  you,
provided  that  you may extend this Agreement for not  more  than  eleven
successive  periods of 30 days each upon notice to us  and  each  of  the
other Underwriters.
     
     Notwithstanding any settlement on the termination of this Agreement,
we  agree to pay our share of any amount payable on account of any claim,
demand  or  liability which may be asserted against the Underwriters,  or
any  of  them,  based  on the claim that the Underwriters  constitute  an
association,  unincorporated business or other separate  entity  and  our
share  of  any  expenses incurred by you in defending  against  any  such
claim,  demand or liability.  We also agree to pay any stamp taxes  which
may  be  assessed and paid after such settlement on account of any  Units
received or sold hereunder for our account.
     
     Notwithstanding any termination of this Agreement, no sales  of  the
Units  shall  be  made  by us at any time except in conformity  with  the
provisions of Section 22(d) of the 1940 Act.

     11.   Default by Other Underwriters.  Default by any one or more  of
the other Underwriters in respect of their several obligations under this
Agreement  shall  neither release you nor us from any of  our  respective
obligations hereunder.

     12.    Notices.  Notices hereunder shall by deemed to have been duly
given  if mailed or telegraphed to us at our address set forth below,  in
the  case  of notices to us, or to you at your address set forth  at  the

are   in  compliance  with  the  capital  requirements  of  Rule  15c-3-1
promulgated  by the Commission under the Securities and Exchange  Act  of
1934,  and we may, in accordance with and pursuant to such Rule  15c-3-1,
agree  to  purchase the amount of Units to be purchased by  you  and  us,
respectively, under the Agreement.

     14.    Miscellaneous.   We confirm that we  are  a  member  in  good
standing of the National Association of Securities Dealers, Inc.
     
     We  confirm  that  we  will take reasonable  steps  to  provide  the
Preliminary  Prospectus or final Prospectus to any person making  written
request  therefor  to us and to make the Preliminary  Prospectus  or  the
final Prospectus available to each person associated with us expected  to
solicit   customers'  orders  for  the  Units  prior  to  the   effective
registration date and the final Prospectus if he is expected to offer the
Units  after the effective date.  We understand that you will  supply  us
upon  our  request with sufficient copies of such prospectuses to  comply
with the foregoing.

     Re:Insured Municipals Income Trust, 165th Insured Multi-Series

Gentlemen:
     
     We  have  served as counsel for Van Kampen Merritt Inc., as  Sponsor
and  Depositor  of Insured Municipals Income Trust, 165th Insured  Multi-
Series  (hereinafter referred to as the "Fund"), in connection  with  the
preparation, execution and delivery of a Trust Agreement dated  September
20,  1994  between  Van  Kampen  Merritt  Inc.,  as  Depositor,  American
Portfolio   Evaluation  Services,  a  division  of  Van  Kampen   Merritt
Investment  Advisory Corp., as Evaluator, and The Bank of  New  York,  as
Trustee,  pursuant to which the Depositor has delivered to and  deposited
Bonds listed in the Schedules to the Trust Agreement with the Trustee and
pursuant  to  which  the Trustee has issued to or on  the  order  of  the
Depositor  a certificate or certificates representing Units of fractional
undivided  interest in and ownership of the several Trusts of  said  Fund
(hereinafter  referred  to  as  the "Units")  created  under  said  Trust
Agreement.
     
     In connection therewith, we have examined such pertinent records and
documents  and  matters of law as we have deemed necessary  in  order  to
enable us to express the opinions hereinafter set forth.
     
     Based upon the foregoing, we are of the opinion that:
     
           1.   The execution and delivery of the Trust Agreement and the
     execution and issuance of certificates evidencing the Units  in  the
     several Trusts of the Fund have been duly authorized; and
     
           2.    The  certificates evidencing the Units  in  the  several
     Trusts of the Fund when duly executed and delivered by the Depositor
     and   the  Trustee  in  accordance  with  the  aforementioned  Trust
     Agreement,  will  constitute valid and binding obligations  of  such
     Trusts and the Depositor in accordance with the terms thereof.
     
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-55407) relating to the Units referred
to  above and to the use of our name and to the reference to our firm  in
said Registration Statement and in the related Prospectus.

                                    Respectfully submitted,

     Re:Insured Municipals Income Trust, 165th Insured Multi-Series

Gentlemen:
     
     We  have acted as counsel for Van Kampen Merritt Inc., Depositor  of
Insured Municipals Income Trust, 165th Insured Multi-Series (the "Fund"),
in connection with the issuance of Units of fractional undivided interest
in  the  several  Trusts  of  said Fund under  a  Trust  Agreement  dated
September 20, 1994 (the "Indenture") between Van Kampen Merritt Inc.,  as
Depositor,  American Portfolio Evaluation Services,  a  division  of  Van
Kampen  Merritt Investment Advisory Corp., as Evaluator, and The Bank  of
New  York,  as  Trustee.   In  this  connection,  we  have  examined  the
Registration Statement, the form of Prospectus proposed to be filed  with
the  Securities  and Exchange Commission, the Indenture  and  such  other
instruments  and documents as we have deemed pertinent.  Based  upon  the
foregoing and upon an investigation of such matters of law as we consider
to  be  applicable,  we are of the opinion that, under  existing  Federal
income tax law:
     
          (i)   Each Trust is not an association taxable as a corporation
     but will be governed by the provisions of subchapter J (relating  to
     trusts) of chapter 1, Internal Revenue Code of 1986 (the "Code").
     
         (ii)    Each Unitholder will be considered as owning a pro  rata
     share  of each asset of the respective Trust in the proportion  that
     the  number  of Units of such Trust held by him bears to  the  total
     number  of  Units  outstanding  of such  Trust.   Under  subpart  E,
     subchapter J of chapter 1 of the Code, income of each Trust will  be
     treated as income of each Unitholder of the respective Trust in  the
     proportion described, and an item of Trust income will have the same
     character in the hands of a Unitholder as it would have in the hands
     of  the  Trustee.  Accordingly, to the extent that the income  of  a
     Trust  consists  of  interest excludable  from  gross  income  under
     Section 103 of the
     
     Code,  such income will be excludable from Federal gross  income  of
     the  Unitholders,  except  in the case of  a  Unitholder  who  is  a
     substantial  user (or a person related to such user) of  a  facility
     financed  through  issuance of any industrial development  bonds  or
     certain private activity bonds held by the respective Trust.  In the
     case  of  such  Unitholder  (and no other)  interest  received  with
     respect  to  his  Units attributable to such industrial  development
     bonds  or  such private activity bonds is includable  in  his  gross
     income.  In the case of certain corporations, interest on the  Bonds
     is  included  in computing the alternative minimum tax  pursuant  to
     Section  56(c)  of the Code, the environmental tax  (the  "Superfund
     Tax") imposed by Section 59A of the Code, and the branch profits tax
     imposed by Section 884 of the Code with respect to U.S. branches  of
     foreign corporations.
     
        (iii)    Gain  or  loss will be recognized to a  Unitholder  upon
     redemption  or sale of his Units.  Such gain or loss is measured  by
     comparing the proceeds of such redemption or sale with the  adjusted
     basis   of  the  Units  represented  by  his  Certificate.    Before
     adjustment, such basis would normally be cost if the Unitholder  had
     acquired  his Units by purchase, plus his aliquot share of  advances
     by the Trustee to the Trust to pay interest on Bonds delivered after
     the  Unitholder's settlement date to the extent that  such  interest
     accrued  on  the  Bonds  during  the period  from  the  Unitholder's
     settlement  date  to  the  date such  Bonds  are  delivered  to  the
     respective Trust, but only to the extent that such advances  are  to
     be repaid to the Trustee out of interest received by such Trust with
     respect to such Bonds.  In addition, such basis will be increased by
     the  Unitholder's  aliquot  share  of  the  accrued  original  issue
     discount with respect to each Bond held by the Fund with respect  to
     which there was an original issue discount at the time the Bond  was
     issued  and  reduced by the annual amortization of bond premium,  if
     any, on Bonds held by the Trust.
     
        (iv)   If the Trustee disposes of a Trust asset (whether by sale,
     payment  on  maturity,  redemption or otherwise)  gain  or  loss  is
     recognized  to the Unitholder and the amount thereof is measured  by
     comparing the Unitholder's aliquot share of the total proceeds  from
     the  transaction with his basis for his fractional interest  in  the
     asset  disposed  of.  Such basis is ascertained by apportioning  the
     tax  basis for his Units among each of the Trust assets (as  of  the
     date  on  which his Units were acquired) ratably according to  their
     values  as  of  the  valuation date nearest the  date  on  which  he
     purchased such Units.  A Unitholder's basis in his Units and of  his
     fractional  interest  in each Trust asset must  be  reduced  by  the
     amount  of  his aliquot share of interest received by the Trust,  if
     any,  on  Bonds delivered after the Unitholder's settlement date  to
     the extent that such interest accrued on the Bonds during the period
     from  the  Unitholder's settlement date to the date such  Bonds  are
     delivered  to  the Trust, must be reduced by the annual amortization
     of  bond  premium, if any, on Bonds held by the Trust  and  must  be
     increased  by  the Unitholder's share of the accrued original  issue
     discount  with respect to each Bond which, at the time the Bond  was
     issued, had original issue discount.
     
          (v)    In  the  case of any Bond held by the  Trust  where  the
     "stated  redemption  price at maturity" exceeds the  "issue  price",
     such  excess shall be original issue discount.  With respect to each
     Unitholder,  upon  the  purchase of  his  Units  subsequent  to  the
     original issuance of Bonds held by the Trust, Section 1272(a)(7)  of
     the Code provides for a reduction in the accrued "daily portion"  of
     such  original issue discount upon the purchase of a Bond subsequent
     to  the Bond's original issue, under certain circumstances.  In  the
     case  of  any  Bond  held  by the Trust the  interest  on  which  is
     excludable  from  gross income under Section 103 of  the  Code,  any
     original issue discount which accrues with respect thereto  will  be
     treated  as  interest which is excludable from  gross  income  under
     Section 103 of the Code.
     
         (vi)   We have examined the Municipal Bond Unit Investment Trust
     Insurance Policies, if any, issued to certain of the Trusts  on  the
     Date  of  Deposit by AMBAC Indemnity Corporation, Financial Guaranty
     Insurance  Corporation or a combination thereof.  Each such  policy,
     or  a  combination of such policies, insures all bonds held  by  the
     Trustee  for  that particular Trust (other than bonds  described  in
     paragraph  (vii)) against default in the prompt payment of principal
     and  interest.   In  our opinion, any amount paid  under  each  said
     policy, or a combination of said policies, which represents 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
     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 bonds, rather than
     the insurer, will pay debt service on the bonds.  Paragraph (ii)  of
     this   opinion  is  accordingly  applicable  to  insurance  proceeds
     representing maturing interest.
     
        (vii)    Certain bonds in the portfolios of certain of the Trusts
     have  been  insured by the issuers thereof against  default  in  the
     prompt  payment  of  principal  and interest.   Insurance  has  been
     obtained for such bonds, or, in the case of a commitment, the  bonds
     will  be  ultimately insured under the terms of  such  an  insurance
     policy,  which  are  designated  as  issuer  insured  bonds  on  the
     portfolio pages of the respective Trusts in the Prospectus  for  the
     Fund, by the issuer of such bonds.  Insurance obtained by the issuer
     is  effective so long as such bonds remain outstanding.  For each of
     these  bonds,  we  have  been advised that the  aggregate  principal
     amount of such bonds listed on the portfolio page for the respective
     Trust  was  acquired by the applicable Trust and  are  part  of  the
     series of such bonds listed on the portfolio page for the respective
     Trust in the aggregate principal amount listed on the portfolio page
     for  the respective Trust.  Based upon the assumption that the bonds
     acquired  by the applicable Trust are part of the series covered  by
     an  insurance  policy  or,  in the case of  a  commitment,  will  be
     ultimately  insured under the terms of such an insurance policy,  it
     is  our  opinion  that any amounts received by the applicable  Trust
     representing maturing interest on such bonds will be excludable from
     Federal  gross  income if, and to the same extent as, such  interest
     would have been so excludable if paid in normal course by the Issuer
     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 bonds, rather than
     the insurer, will pay debt service on the bonds.  Paragraph (ii)  of
     this opinion is accordingly applicable to such payment.
     
     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  accrued  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.
     
     Because  the  Trusts  do  not include any "private  activity"  bonds
within  the  meaning  of  Section 141 of the  Code  issued  on  or  after
August 8, 1986, none of the Trust Fund's interest income shall be treated
as  an item of tax preference when computing the alternative minimum tax.
In   the  case  of  corporations,  for  taxable  years  beginning   after
December  31,  1986, the alternative minimum tax and  the  Superfund  Tax
depend upon the corporation's taxable income with certain adjustments.
     
     Pursuant  to Section 56(c) of the Code, one of the adjustment  items
used in computing AMTI and the Superfund Tax of a corporation (other than
an  S  Corporation, Regulated Investment Company, Real Estate  Investment
Trust  or  REMIC) for taxable years beginning after 1989,  is  an  amount
equal  to  75%  of  the  excess of such corporation's  "adjusted  current
earnings"  over an amount equal to its AMTI (before such adjustment  item
and the alternative tax net operating loss deduction).  "Adjusted current
earnings"  includes all tax-exempt interest, including  interest  on  all
Bonds in the Trust, and tax-exempt original issue discount.
     
     Effective  for  tax  returns  filed after  December  31,  1987,  all
taxpayers  are required to disclose to the Internal Revenue  Service  the
amount of tax-exempt interest earned during the year.
     
     Section  265  of the Code provides for a reduction in  each  taxable
year  of 100 percent of the otherwise deductible interest on indebtedness
incurred  or  continued  by  financial  institutions,  to  which   either
Section  585  or  Section 593 of the Code applies, to purchase  or  carry
obligations  acquired  after August 7, 1986, the  interest  on  which  is
exempt  from  Federal income taxes for such taxable  year.   Under  rules
prescribed by Section 265, the amount of interest otherwise deductible by
such  financial institutions in any taxable year which is  deemed  to  be
attributable  to  tax-exempt obligations acquired after August  7,  1986,
will  be  the amount that bears the same ratio to the interest  deduction
otherwise  allowable (determined without regard to Section  265)  to  the
taxpayer  for  the taxable year as the taxpayer's average adjusted  basis
(within  the meaning of Section 1016) of tax-exempt obligations  acquired
after August 7, 1986, bears to such average adjusted basis for all assets
of   the  taxpayer,  unless  such  financial  institution  can  otherwise
establish,  under regulations, to be prescribed by the Secretary  of  the
Treasury, the amount of interest on indebtedness incurred or continued to
purchase or carry such obligations.
     
     We  also call attention to the fact that, under Section 265  of  the
Code, interest on indebtedness incurred or continued to purchase or carry
Units  is  not deductible for Federal income tax purposes.   Under  rules
used  by the Internal Revenue Service for determining when borrowed funds
are  considered used for the purpose of purchasing or carrying particular
assets,  the purchase of Units may be considered to have been  made  with
borrowed  funds even though the borrowed funds are not directly traceable
to the purchase of Units.  However, these rules generally do not apply to
interest  paid  on indebtedness incurred for expenditures of  a  personal
nature  such  as  a mortgage incurred to purchase or improve  a  personal
residence.
     
     "The  Revenue  Reconciliation Act of 1993" (the "Tax Act")  subjects
tax-exempt  bonds to the market discount rules of the code effective  for
bonds purchased after April 30, 1993.  In general, market discount is the
amount  (if any) by which the stated redemption price at maturity exceeds
an  investor's purchase price (except to the extent that such difference,
if  any,  is  attributable to original issue discount not  yet  accrued).
Market  discount can arise based on the price a Trust pays for  Bonds  or
the  price  a Unitholder pays for his or her Units.  Under the  Tax  Act,
accretion  of market discount is taxable as ordinary income; under  prior
law,  the  accretion had been treated as capital gain.   Market  discount
that  accretes while a Trust holds a Bond would be recognized as ordinary
income  by  the Unitholders when principal payments are received  on  the
Bond,  upon sale or at redemption (including early redemption),  or  upon
the sale of redemption of his or her Units, unless a Unitholder elects to
include market discount in taxable income as it accrues.
     
     We  have  also examined the income tax law of the State of Missouri,
which  is  based upon the Federal law, to determine its applicability  to
the  Insured Missouri Trust (the "Missouri Trust") being created as  part
of  the  Fund and to the holders of Units in the Missouri Trust  who  are
residents of the State of Missouri ("Missouri Unitholders").
     
     The assets of the Trust will consist of interest-bearing obligations
issued  by  or  on  behalf  of  the State of Missouri  (the  "State")  or
counties,  municipalities, authorities or political subdivisions  thereof
(the  "Missouri Bonds") or by the Commonwealth of Puerto Rico,  Guam  and
the  United States Virgin Islands (the "Possession Bonds") (collectively,
the "Bonds").
     
     Although we express no opinion with respect to the issuance  of  the
Bonds,  in rendering our opinion expressed herein, we have assumed  that:
(i)  the  Bonds  were  validly  issued,  (ii)  the  interest  thereon  is
excludible  from  gross  income for federal income  tax  purposes,  (iii)
interest  on  the Bonds, if received directly by a Unitholder,  would  be
exempt  from  the  income tax imposed by the State of  Missouri  that  is
applicable  to individuals and corporations (the "Missouri  State  Income
Tax").  This opinion does not address the taxation of persons other  than
full time residents of Missouri.
     
     Based  on  the  foregoing, and based on review and consideration  of
existing  laws  of the State as of this date, it is our opinion,  and  we
herewith advise you, as follows:
     
          (1)    The  Missouri Trust is not an association taxable  as  a
     corporation for Missouri income tax purposes, and each Unitholder of
     the  Missouri  Trust  will be treated as the owner  of  a  pro  rata
     portion  of  the Trust and the income of such portion of  the  Trust
     will  be treated as the income of the Unitholder for Missouri  State
     Income Tax purposes;
     
          (2)   Interest paid and original issue discount, if any, on the
     Bonds  which would be exempt from the Missouri State Income  Tax  if
     received  directly by a Unitholder will be exempt from the  Missouri
     State Income Tax when received by the Missouri Trust and distributed
     to   such  Unitholder;  however,  no  opinion  is  expressed  herein
     regarding  the  Missouri Trust and distributed to Unitholders  under
     any  other tax imposed pursuant to Missouri law, including  but  not
     limited  to  the  franchise  tax imposed on  financial  institutions
     pursuant to Chapter 148 of the Missouri Statutes.
     
          (3)    To  the  extent  that interest paid and  original  issue
     discount,  if  any, derived from the Missouri Trust by a  Unitholder
     with respect to Possession Bonds is excludable from gross income for
     Federal  income tax purposes pursuant to 48 U.S.C. 745,  48  U.S.C.
     1423a,  and 48 U.S.C. 1403, such interest paid and original  issue
     discount,  if any, will not be subject to the Missouri State  Income
     Tax;  however, no opinion is expressed herein regarding taxation  of
     interest  paid  and original issue discount, if any,  on  the  Bonds
     received by the Missouri Trust and distributed to Unitholders  under
     any  other tax imposed pursuant to Missouri law, including  but  not
     limited  to  the  franchise  tax imposed on  financial  institutions
     pursuant to Chapter 148 of the Missouri Statutes.
     
          (4)   Each Unitholder of the Missouri Trust will recognize gain
     or  loss  for  Missouri  State Income Tax purposes  if  the  Trustee
     disposes of a bond (whether by redemption, sale, or otherwise) or if
     the  Unitholder redeems or sells Units of the Missouri Trust to  the
     extent that such a transaction results in a recognized gain or  loss
     to  such  Unitholder for Federal income tax purposes.   Due  to  the
     amortization of bond premium and other basis adjustments required by
     the  Internal  Revenue Code, a Unitholder, under some circumstances,
     may  realize taxable gain when his or her Units are sold or redeemed
     for an amount equal to their original cost.
     
         (5)   Any insurance proceeds paid under policies which represent
     maturing interest on defaulted obligations which are excludable from
     gross income for Federal income tax purposes will be excludable from
     Missouri State Income Tax to the same extent as such interest  would
     have  been  paid  by the issuer of such Bonds held by  the  Missouri
     Trust; however, no opinion is expressed herein regarding taxation of
     interest  paid  and original issue discount, if any,  on  the  bonds
     received by the Missouri Trust and distributed to Unitholders  under
     any  other tax imposed pursuant to Missouri law, including  but  not
     limited  to  the  franchise  tax imposed on  financial  institutions
     pursuant to Chapter 148 of the Missouri Statutes.
     
          (6)   The Missouri State Income Tax does not permit a deduction
     of  interest paid or incurred on indebtedness incurred or  continued
     to  purchase  or carry Units in the Missouri Trust, the interest  on
     which is exempt from such Tax.
     
         (7)   The Missouri Trust will not be subject to the Kansas City,
     Missouri  Earnings  and Profits Tax and each Unitholder's  share  of
     income of the Bonds held by the Missouri Trust will not generally be
     subject to the Kansas City, Missouri Earnings and Profits Tax or the
     City  of  St.  Louis  Earnings Tax (except in the  case  of  certain
     Unitholders, including corporations, otherwise subject  to  the  St.
     Louis City Earnings Tax).
     
     Units  may  be  subject to the Missouri Estate  Tax.   We  have  not
examined any of the Bonds to be deposited and held in the Missouri  Trust
or  the  proceedings for the issuance thereof or the  opinions  of  bonds
counsel with respect thereto, and therefore express no opinion as to  the
exemption from the Missouri State Income Tax of interest on the  Missouri
Bonds if received directly by a Unitholder.
     
     We have also examined the income tax law of the State of Oklahoma to
determine its applicability to the Oklahoma IM-IT Trust (the "Oklahoma IM-
IT  Trust") being created as a part of the Fund and to the holders of the
Units  in  the  Oklahoma IM-IT Trust who are residents of  the  State  of
Oklahoma ("Oklahoma Unitholders").
     
     The  assets  of the Oklahoma IM-IT Trust will consist  of  interest-
bearing obligations issued by or on behalf of the State of Oklahoma  (the
"State")   or   counties,   municipalities,  authorities   or   political
subdivisions  thereof (the "Oklahoma Bonds") or by  the  Commonwealth  of
Puerto  Rico, Guam and the United States Virgin Islands (the  "Possession
Bonds") (collectively, the "Bonds").  At the respective times of issuance
of the Oklahoma Bonds, certain, but not necessarily all, of the issues of
the  Oklahoma  Bonds  may have been accompanied by  an  opinion  of  bond
counsel  to  the  respective issuing authorities that  interest  on  such
Oklahoma  Bonds  (the "Oklahoma Tax-Exempt Bonds") are  exempt  from  the
income  tax  imposed  by  the State of Oklahoma  that  is  applicable  to
individuals  and  corporations (the "Oklahoma State  Income  Tax").   The
Oklahoma IM-IT Trust may include Oklahoma Bonds the interest on which  is
subject to the Oklahoma State Income Tax (the "Oklahoma Taxable Bonds").
     
     Although we express no opinion with respect to the issuance  of  the
Bonds,  in rendering our opinion expressed herein, we have assumed  that:
(i)  the  Bonds  were  validly  issued, (ii)  the  interest   thereon  is
excludable  from gross income for federal income tax purposes  and  (iii)
interest on the Oklahoma Tax-Exempt Bonds, if received directly by a Unit
holder,  would  be  exempt from the Oklahoma State Income  Tax.   At  the
respective  times  of  issuance of the Bonds, opinions  relating  to  the
validity  thereof and to the exemption of interest thereon  from  federal
income  tax  were  rendered  by bond counsel to  the  respective  issuing
authorities.  In addition, with respect to the Oklahoma Tax-Exempt Bonds,
bond  counsel  to  the issuing authorities rendered opinions  as  to  the
exemption  of interest from the Oklahoma State Income Tax.  We  have  not
made any review for the Trust of the proceedings relating to the issuance
of  the  Bonds  or of the bases for the opinions rendered  in  connection
therewith.   This opinion does not address the taxation of persons  other
than full time residents of Oklahoma.
     
     Based  on  the  foregoing, and based on review and consideration  of
existing  laws  of the State as of this date, it is our opinion,  and  we
herewith advise you, as follows:
     
         (1)   For Oklahoma State Income Tax purposes, the Oklahoma IM-IT
     Trust  is  not  an  association  taxable  as  a  corporation,   each
     Unitholder of the Oklahoma IM-IT Trust will be treated as the  owner
     of  a pro rata portion of the Oklahoma IM-IT Trust and the income of
     such  portion  of the Oklahoma IM-IT Trust will be  treated  as  the
     income of the Unitholder.
     
          (2)   Interest paid and original issue discount, if any, on the
     Bonds  which would be exempt from the Oklahoma State Income  Tax  if
     received  directly by a Unitholder will be exempt from the  Oklahoma
     State  Income  Tax  when received by the Oklahoma  IM-IT  Trust  and
     distributed to such Unitholder.
          
          A  Unitholder's  pro  rata portion of  any  interest  paid  and
     original issue discount, if any, on the Bonds which would be subject
     to  the  Oklahoma  State  Income  Tax  if  received  directly  by  a
     Unitholder, including, for example, interest paid and original issue
     discount, if any, on the Oklahoma Taxable Bonds, will be taxable  to
     such Unitholder for Oklahoma State Income Tax purposes when received
     by the Oklahoma IM-IT Trust.
     
          (3)    To  the  extent  that interest paid and  original  issue
     discount,  if  any,  derived  from the Oklahoma  IM-IT  Trust  by  a
     Unitholder with respect to Possession Bonds is excludable from gross
     income  for Federal income tax purposes pursuant to 48 U.S.C.  475,
     48  U.S.C.  1423A,  and  48 U.S.C. 1403, such  interest  paid  and
     original discount, if any, will not be subject to the Oklahoma State
     Income Tax.
     
         (4)   Each Unitholder of the Oklahoma IM-IT Trust will recognize
     gain  or  loss for Oklahoma State Income Tax purposes if the Trustee
     disposes of a Bond (whether by redemption, sale, or otherwise) or if
     the Unitholder redeems or sells Units of the Oklahoma IM-IT Trust to
     the  extent that such a transaction results in a recognized gain  or
     loss to such Unitholder for federal income tax purposes.  Due to the
     amortization of bond premium and other basis adjustments required by
     the  Internal  Revenue Code, a Unitholder, under some circumstances,
     may  realize taxable gain when his or her Units are sold or redeemed
     for an amount equal to their original cost.
     
          (5)    Although no opinion is expressed herein,  we  have  been
     informally advised by the Oklahoma Tax Commission that any insurance
     proceeds  paid under policies which represent maturing  interest  on
     defaulted  obligations which are excludable from  gross  income  for
     federal income tax purposes should be excludable from Oklahoma State
     Income  Tax to the same extent as such interest would have  been  if
     paid by the issuer of such Bonds held by the Oklahoma IM-IT Trust.
     
          (6)   The Oklahoma State Income Tax does not permit a deduction
     of  interest paid or incurred on indebtedness incurred or  continued
     to  purchase or carry Units in the Oklahoma IM-IT Trust the interest
     on which is exempt from such tax.
     
          (7)    Although no opinion is expressed herein,  we  have  been
     informally advised by the Oklahoma Tax Commission that the  Oklahoma
     IM-IT Trust, in part because of its status as a "grantor trust"  for
     federal  income tax purposes, should not be subject to the  Oklahoma
     state franchise tax.
     
     The  scope  of this opinion is expressly limited to the matters  set
forth herein, and we express no other opinions of law with respect to the
state  of  local  taxation  of the Oklahoma IM-IT  Trust,  the  purchase,
ownership or disposition of Units or the Unitholders under Oklahoma law.
     
     We  have  not examined any of the Bonds to be deposited and held  in
the  Oklahoma IM-IT 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 either the Oklahoma State Income Tax
or the Oklahoma Minimum Tax of interest on the Oklahoma Bonds if received
directly by a Unitholder.
                                    
                                    Very truly yours,

Insured Municipals Income Trust
  165th Insured Multi-Series
The Bank of New York,
  As Trustee
101 Barclay Street, 17 West
New York, New York 10286

Dear Sirs:
     
     We have acted as special counsel for the Insured Municipals Income Trust,
165th  Insured  Multi-Series  (the "Fund") consisting  of  Insured  Municipals
Income  Trust,  Series 333, Michigan Insured Municipals Income  Trust,  Series
120,  Missouri Insured Municipals Income Trust, Series 84 and Oklahoma Insured
Municipals  Income  Trust, Series 13, (individually the  "Trust"  and  in  the
aggregate  the "Trusts") for the purposes of determining the applicability  of
certain New York taxes under the circumstances hereinafter described.
     
     The  Fund  is  created pursuant to a Trust Agreement  (the  "Indenture"),
dated  as of today (the "Date of Deposit") among Van Kampen Merritt Inc.  (the
"Depositor"), American Portfolio Evaluation Services, a division of Van Kampen
Merritt  Investment Advisory Corp., as Evaluator, and The Bank of New York  as
Trustee (the "Trustee").  As described in the prospectus relating to the  Fund
dated today to be filed as an amendment to a registration statement previously
filed with the Securities and Exchange Commission (file number 33-55407) under
the Securities Act of 1933, as amended (the "Prospectus" and the "Registration
Statement"),  the objectives of the Fund are the generation of  income  exempt
from  Federal taxation and as regards each of the "State" Trusts  exempt  from
income  tax and personal property tax of the State denominated in the name  of
that  "State"  Trust, if any, to the extent indicated in the  Prospectus.   No
opinion is expressed herein with regard to the Federal or State tax aspects of
the bonds, the Fund, Trusts (other than New York),
units  of the Trusts (the "Units") other than New York, or any interest, gains
or losses in respect thereof.
     
     As  more  fully  set  forth in the Indenture and in the  Prospectus,  the
activities of the Trustee will include the following:
     
     On  the Date of Deposit, the Depositor will deposit with the Trustee with
respect  to each of the Trusts, the total principal amount of interest bearing
obligations  and/or  contracts  for  the purchase  thereof  together  with  an
irrevocable letter of credit in the amount required for the purchase price and
accrued  interest, if any, and an insurance policy purchased by the  Depositor
evidencing  the  insurance guaranteeing the timely payment  of  principal  and
interest of tile obligations comprising the corpus of such trusts oilier  than
those  obligations the timely payment of principal and interest of  which  are
guaranteed by an insurance policy purchased by the issuer thereof or  a  prior
owner, which may be the Depositor prior to the Date of Deposit, as more  fully
set forth in the Prospectus with respect to each Trust.
     
     We  understand with respect to the obligations described in the preceding
paragraph  that  all  insurance, whether purchased by the Depositor,  a  prior
owner  or the issuer, provides, or will provide, that the amount paid  by  the
insurer  in  respect of any bond may not exceed the amount  of  principal  and
interest due on the bond and such payment will in no event relieve the  issuer
from its continuing obligation to pay such defaulted principal and interest in
accordance with the terms of the obligation.
     
     The  Trustee will not participate in the selection of the obligations  to
be  deposited in the Fund, and, upon the receipt thereof, will deliver to  the
Depositor  a  registered certificate for the number of Units representing  the
entire capital of each of the Trusts as more fully set forth in the Prospectus
and  the  Registration  Statement.   The  Units,  which  are  represented   by
certificates ("Certificates"), will be offered to the public by the Prospectus
upon the effectiveness of the Registration Statement.
     
     The  duties of the Trustee, which are ministerial in nature, will consist
primarily of crediting the appropriate accounts with interest received by each
of  the Trusts and with the proceeds from the disposition of obligations  held
in  the Trusts and the distribution of such interest and proceeds to the  Unit
holders  of  that  Trust.   The  Trustee will also  maintain  records  of  the
registered holders of Certificates representing an interest in each Trust  and
administer the redemption of Units by such Certificate holders and may perform
certain  administrative  functions with respect  to  an  automatic  investment
option.
     
     Generally, obligations held in the Fund may be removed therefrom  by  the
Trustee  only upon redemption prior to their stated maturity, at the direction
of  the  Depositor in the event of an advance refunding or upon the occurrence
of  certain other specified events which adversely affect the sound investment
character of the Fund, such as default by the issuer in payment of interest or
principal  on  the  obligation and no provision for payment is  made  therefor
either  pursuant to insurance or otherwise and the Depositor fails to instruct
the  Trustee,  within  thirty  (30)  days after  notification,  to  hold  such
obligation.
     
     Prior  to the termination of the Fund, the Trustee is empowered  to  sell
Bonds,  from  a  list  furnished by the Evaluator, only  for  the  purpose  of
redeeming Units tendered to it and of paying expenses for which funds are  not
available.  The Trustee does not have the power to vary the investment of  any
Unit  holder in the Fund, and under no circumstances may the proceeds of  sale
of  any obligations held by the Fund be used to purchase new obligations to be
held therein.
     
     Article  9-A of the New York Tax Law imposes a franchise tax on  business
corporations,  and, for purposes of that Article, Section 208(l)  defines  the
term "corporation" to include, among other things, "any business conducted  by
a   trustee  or  trustees  wherein  interest  or  ownership  is  evidenced  by
certificate or other written instrument."
     
     The Regulations promulgated under Section 208 provide as follows:
          
          A  business  conducted by a trustee or trustees  in  which
          interest or ownership is evidenced by certificate or other
          written  instrument includes, but is not  limited  to,  an
          association commonly referred to as a "business trust"  or
          "Massachusetts trust".  In determining whether  a  trustee
          or  trustees  are conducting a business, the form  of  the
          agreement is of significance but is not controlling.   The
          actual  activities of the trustee or trustees,  not  their
          purposes and powers, will be regarded as decisive  factors
          in  determining whether a trust is subject  to  tax  under
          Article  9-A.   The  mere  investment  of  funds  and  the
          collection    of   income   therefrom,   with   incidental
          replacement of securities and reinvestment of funds,  does
          not constitute the conduct of a business in the case of  a
          business  conducted by a trustee or trustees. 20 NYCRR  1-
          2.3(b)(2) (July 11, 1990).
     
     New  York  cases  dealing with the question of whether a  trust  will  be
subject to the franchise tax have also delineated the general rule that  where
a  trustee  merely  invests  funds and collects  and  distributes  the  income
therefrom,  the  trust is not engaged in business and is not  subject  to  the
franchise  tax.   Burrell v. Lynch, 274 A.D. 347, 84 N.Y.S.2d 171  (3rd  Dept.
1948), order resettled, 274 A.D. 1083, 85 N.Y.S.2d 705 (3rd Dept. 1949).
     
     In  an opinion of the Attorney General of the State of New York, 47  N.Y.
Atty. Gen. Rep. 213 (Nov. 24, 1942), it was held that where the trustee of  an
unincorporated  investment  trust was without authority  to  reinvest  amounts
received  upon the sales of securities and could dispose of securities  making
up  the  trust  only  upon the happening of certain specified  events  or  the
existence  of certain specified conditions, the trust was not subject  to  the
franchise tax.
     
     In   the  instant  situation,  the  Trustee  is  not  empowered  to  sell
obligations  contained  in the corpus of the Fund and  reinvest  the  proceeds
therefrom.   Further,  the  power  to sell  such  obligations  is  limited  to
circumstances in which the creditworthiness or soundness of the obligation  is
in question or in which cash is needed to pay redeeming Unit holders or to pay
expenses, or where the Fund is liquidated pursuant to the termination  of  the
Indenture.   Only  in  circumstances in which  the  issuer  of  an  obligation
attempts  to  refinance it can the Trustee exchange an obligation  for  a  new
security.  In substance, the Trustee will merely collect and distribute income
and will not reinvest any income or proceeds, and the Trustee has no power  to
vary the investment of any Unit holder in the Fund.
     
     Under  Subpart  E  of Part 1, Subchapter J of Chapter I of  the  Internal
Revenue Code of 1986, as amended (the "Code"), the grantor of a trust will  be
deemed  to be the owner of the trust under certain circumstances and therefore
taxable  on  his  proportionate interest in the income  thereof.   Where  this
Federal  tax rule applies, the income attributed to the grantor will  also  be
income  to him for New York income tax purposes.  See TSB-M78(9)(c), New  York
Department of Taxation and Finance, June 23, 1978.
     
     Article 22 (Personal Income Tax) of the New York Tax Law imposes a tax on
a  New  York  State resident individual's State adjusted gross  income.   Such
amount is defined by Section 612 as his Federal adjusted gross income, with an
addition  for  interest  income on the obligations of  a  State  or  political
subdivision  of  a  state other than New York, if excluded  from  his  federal
adjusted  gross  income.   Such amount is defined by  Section  T46112  of  the
Administrative  Code  of  the City of New York as Ins Federal  adjusted  gross
income, with an addition for interest income on the obligations of a state  or
political  subdivision of a state other than New York, if  excluded  from  his
federal  adjusted gross income. 48 U.S.C.  Section 745 exempts interest  on  a
bond  issued  by  the  Government of Puerto Rico or  a  political  subdivision
thereof  from  tax  of the United States, of any State,  and  of  any  state's
county,  municipality,  or municipal subdivision thereof.  48  U.S.C.  Section
1423a  exempts interest on a bond issued by the Government of Guam or  by  its
authority  from  taxation  by  the  United  States,  any  state  or  political
subdivision.   The New York Trust holds only obligations issued  by  New  York
State  or a political subdivision thereof or by the Government of Puerto  Rico
or  a  political subdivision thereof, or by the Government of Guam or  by  its
authority.
     
     By  letter,  dated  today, Messrs. Chapman and Cutler,  counsel  for  the
Depositor,  rendered their opinion that each Unit holder of a  Trust  will  be
considered  as  owning a share of each asset of that Trust in  the  proportion
that  the  number  of Units held by such holder bears to the total  number  of
Units  outstanding and the income of a Trust will be treated as the income  of
each  Unit  holder of that Trust in said proportion pursuant to Subpart  E  of
Part 1, Subchapter J of Chapter I of the Code.
     
     Based  on the foregoing and of the opinion of Messrs. Chapman and Cutler,
co-counsel for the Depositor, dated today, upon which we specifically rely, we
are  of  the  opinion that under existing laws, rulings, and  court  decisions
interpreting the laws of the State and City of New York:

      1.   Each of the Trusts will not constitute an association taxable as  a
corporation under New York law, and, accordingly, will not be subject  to  tax
on  its  income  under the New York State franchise tax or the New  York  City
general corporation tax.

      2.    The income of each of the Trusts will be treated as the income  of
the Unit holders under the income tax laws of the State and City of New York.

      3.   Resident individuals of New York State and City will not be subject
to  the  State  or  City  personal income taxes on interest  income  on  their
proportionate shares of interest income earned by a Trust on any obligation of
New  York  State  or a political subdivision thereof or of the  Government  of
Puerto Rico or a political subdivision thereof or of the Government of Guam or
by  its authority, to the extent such income is excludable from Federal  gross
income under Code Section 103.

      4.    Any  amounts  paid under the insurance policies purchased  by  the
Depositor  and  deposited  with the Trustee, as more  fully  described  above,
representing  maturing interest on defaulted obligations held by  the  Trustee
will not be subject to New York State or City income taxes if, and to the same
extent as, such amounts would have been excludable from New York State or City
income  taxes  if  paid  by  the  issuer.  Paragraph  3  of  this  opinion  is
accordingly applicable to such policy proceeds representing maturing interest.

      5.    Any amounts paid under an insurance policy purchased by the issuer
of an obligation or a prior owner, as more fully described above, representing
maturing  interest on such defaulting obligation held by the Trustee will  not
be  subject to New York State or City income taxes if, and to the same  extent
as, such amounts would have been excludable from New York State or City income
taxes  if  paid  by  the issuer.  Paragraph 3 of this opinion  is  accordingly
applicable to such policy proceeds representing maturing interest.

      6.   Resident individuals of New York State and City who hold Units will
recognize  gain or loss, if any, under the State or City personal  income  tax
law  if the Trustee disposes of a Fund asset.  The amount of such gain or loss
is measured by comparing the Unit holder's aliquot share of the total proceeds
from  the transaction with his basis for his fractional interest in the  asset
disposed of.  Such basis is ascertained by apportioning the tax basis for  his
Units among each of the Trust's assets (as of the date on which is Units  were
acquired)  ratably according to their values as of the valuation date  nearest
the date on which he purchased such Units.  A Unit holder's basis in his Units
and  of  his fractional interest in the Trust's assets must be reduced by  the
amount  of  his aliquot share of interest received by the Trust,  if  any,  on
bonds  delivered  after the settlement date to the extent that  such  interest
accrued on the Bonds during the period from the Unit holder's settlement  date
to  the  date such Bonds are delivered to that Trust and must be adjusted  for
amortization of bond premium or accretion of original issue discount, if  any,
on tax-exempt obligations held by the Trust.

      7.   Resident individuals of New York State and City who hold Units will
recognize  gain or loss, if any, under the State or City personal  income  tax
law  if  the  Unit holder sells or redeems any Units.  Such gain  or  loss  is
increased  by  comparing  the proceeds of such redemption  or  sale  with  the
adjusted  basis of the Units redeemed or sold.  Before adjustment, such  basis
would  normally be cost if the Unit holder had acquired his Units by purchase,
plus  his aliquot share of advances by the Trustee to the Fund to pay interest
on  Bonds delivered after the Unit holder's settlement date to the extent that
such  interest accrued on the Bonds during the period from the settlement date
to  the date such Bonds are delivered to the Fund, but only to the extent that
such advances are to be repaid to the Trustee out of interest received by  the
Fund with respect to such Bonds.

     8.   Unit holders who are not residents of New York State are not subject
to  the  personal income tax law thereof with respect to any interest or  gain
derived  from  a Trust or any gain from the sale or other disposition  of  the
Units,  except  to  the  extent that such interest or gain  is  from  property
employed in a business, trade, profession or occupation carried on in New York
state.
     
     In  addition, we are of the opinion that no New York State stock transfer
tax  will be payable in respect of any transfer of the Certificates by  reason
of the exemption contained in paragraph (a) of Subdivision 8 of Section 270 of
the New York Tax Law.
     
     We  hereby  consent to the filing of this opinion as an  exhibit  to  the
Registration  Statement relating to the Units and to the use of our  name  and
the reference to our firm in the Registration Statement and in the Prospectus.

     Re:Insured Municipals Income Trust, 165th Insured Multi-Series
         (Michigan Insured Municipals Income Trust, Series 120)

Gentlemen:
     
     We  have  acted as special Michigan counsel to you as  sponsors  and
trustees  of  Insured Municipals Income Trust, 165th Insured Multi-Series
(Michigan Insured Municipals Income Trust, Series 120 referred  to  above
(the "Fund").  You have asked that we, acting in such capacity, render an
opinion  to you with respect to certain matters relating to the  issuance
of  the  units of fractional undivided interest in the Fund (the "Units")
pursuant  to  a  Registration  Statement  on  Form  S-6  filed  with  the
Securities   and  Exchange  Commission  (the  "Commission")   under   the
Securities Act of 1933, as amended (the "Registration Statement").
     
     You  have  requested  our  opinion as to the  applicability  to  the
Michigan Insured Municipals Income Trust (the "Michigan Trust")  and  the
holders  of  Units  (the "Holders"), each of which Units  represents  the
ownership  of a specified fractional undivided interest in the assets  of
the  Michigan Trust, of the Michigan Income Tax Act (M.C.L.A. 206.1  et
seq.; M.S.A. 7.557 (101) et seq.) (the "Michigan Income Tax"), the City
Income Tax Act (M.C.L.A. 141.501 et seq.; M.S.A. 5.3194 (1) et seq.),
which  incorporates  the "Uniform City Income Tax Ordinance,"  the  First
Class  School District excise tax upon income (M.C.L.A. 380.451; M.S.A.
SS15.4451)  (collectively, the "income tax laws"),  the  Michigan  Single
Business  Tax Act (M.C.L.A. 208.1 et seq.; M.S.A. 7.558(1)  et  seq.)
(the  "Single  Business  Tax")  and the  Michigan  Tax  on  ownership  of
Intangible   Personal  Property  (M.C.L.A.  205.131  et  seq.;   M.S.A.
7.556(1) et seq.) (the "Intangibles Tax").  You have also requested our
opinion  regarding the tax status of proceeds payable from  an  insurance
policy  to  be obtained by either the Fund or by the issuer of the  Bonds
involved,  guaranteeing prompt payment of principal and interest  on  all
Bonds in the portfolio of the Fund.
     
     The Michigan Trust, its formation, its proposed method of operation,
the  rights of owners of Certificates representing Units, the  nature  of
such ownership and the portfolio of investments of the Michigan Trust are
described and set forth in the Prospectus dated September 20, 1994, filed
with the Securities and Exchange commission in Registration No. 33-55407.
In  giving our opinion set forth hereunder, we have relied upon the facts
contained in such Registration Statement, including the fact that, at the
respective dates of issuance of the underlying Debt obligations, opinions
of  bond counsel to the respective Michigan authorities issuing such Debt
Obligations  were  given  with  respect  to  the  validity  of  the  Debt
Obligations  and the exemption of the same, and of the interest  thereon,
from Michigan taxation.
     
     Based on the above, it is our opinion that:
     
     The Michigan Trust and the owners of Units will, in our opinion,  be
treated  for  purposes of the Michigan income tax  laws  and  the  Single
Business Tax in substantially the same manner as they are for purposes of
the  Federal income tax laws, as currently enacted.  Accordingly, we have
relied  upon  the  opinion  of Messrs.  Chapman  and  Cutler  as  to  the
applicability  of Federal income tax under the Internal Revenue  Code  of
1986,  as  currently amended, to the Michigan Trust and  the  Holders  of
Units.
     
     Under  the  income tax laws of the State of Michigan,  the  Michigan
Trust  is not an association taxable as a corporation; the income of  the
Michigan  Trust will be treated as the income of the Holders of Units  of
the  Michigan  Trust  and be deemed to have been received  by  them  when
received by the Michigan Trust.  Interest on the Debt Obligations in  the
Michigan  Trust  which is exempt from tax under the Michigan  income  tax
laws  when received by the Michigan Trust will retain its status  as  tax
exempt interest to the Holders of Units of the Michigan Trust.
     
     For  purposes of the Michigan income tax laws, each Holder of  Units
of  the  Michigan Trust will be considered to have received his pro  rata
share  of interest on each Debt Obligation in the Michigan Trust when  it
is  received by the Michigan Trust, and each Holder will have  a  taxable
event  when the Michigan Trust disposes of a Debt Obligation (whether  by
sale,  exchange,  redemption or payment at maturity)  or  when  the  Unit
Holder  redeems  or  sells  his  Unit,  to  the  extent  the  transaction
constitutes  a  taxable event for Federal income tax purposes.   The  tax
cost of each Unit to a Unit Holder will be established and allocated  for
purposes of the Michigan income tax laws in the same manner as such  cost
is established and allocated for Federal income tax purposes.
     
     Under  the  Michigan  Intangibles Tax, the  Michigan  Trust  is  not
taxable and the pro rata ownership of the underlying Debt obligations, as
well  as the interest thereon, will be exempt to the Holders of Units  to
the  extent  the Michigan Trust consists of obligations of the  State  of
Michigan  or  its  political  subdivisions  or  municipalities,   or   of
obligations of possessions of the United States.
     
     The  Michigan Single Business Tax replaced the tax on corporate  and
financial  institution  income under the Michigan  Income  Tax,  and  the
intangible  tax with respect to those intangibles of persons  subject  to
the  Single  Business Tax the income from which would  be  considered  in
computing  the  Single Business Tax.  Persons are subject to  the  Single
Business Tax only if they are  engaged in "business activity," as defined
in the Act.  Under the Single Business Tax, both interest received by the
Michigan  Trust  on  the  underlying  Debt  Obligations  and  any  amount
distributed from the Michigan Trust to a Unit Holder, if not included  in
determining taxable income for Federal income tax purposes, is  also  not
included in the adjusted tax base upon which the Single Business  Tax  is
computed,  of  either  the Michigan Trust or the Unit  Holders.   If  the
Michigan  Trust  or  the Unit Holders have a taxable  event  for  Federal
income tax purposes when the Michigan Trust disposes of a Debt Obligation
(whether  by  sale, exchange, redemption or payment at maturity)  or  the
Holder  redeems or sells his Unit, an amount equal to any  gain  realized
from  such taxable event which was included in the computation of taxable
income  for  Federal  income tax purposes (plus an amount  equal  to  any
capital gain of an individual realized in connection with such event  but
excluded in computing that individual's Federal taxable income)  will  be
included  in  the tax base against which, after allocation, apportionment
and other adjustments, the Single Business Tax is computed.  The tax base
will be reduced by an amount equal to any capital loss realized from such
a  taxable  event,  whether  or  not the capital  loss  was  deducted  in
computing Federal taxable income in the year the loss occurred.   Holders
should consult their tax advisor as to their status under Michigan law.
     
     Any proceeds paid under an insurance policy issued to the Trustee of
the Fund, or paid under individual policies obtained by issuers of Bonds,
which, when received by the Unit Holders, represent maturing interest  on
defaulted  obligations held by the Trustee, will be excludable  from  the
Michigan income tax laws and the Single Business Tax if, and to the  same
extent  as,  such interest would have been so excludable if paid  by  the
issuer  of the defaulted obligations.  While treatment under the Michigan
Intangibles  Tax  is  not  premised upon  the  characterization  of  such
proceeds  under  the  Internal Revenue Code, the Michigan  Department  of
Treasury should adopt the same approach as under the Michigan income  tax
laws and the Single Business tax.
     
     Chapman  and  Cutler  of 111 West Monroe Street,  Chicago,  Illinois
60603,  are entitled to rely on this opinion as though it were  addressed
to them.
     
     We  also  advise you that, as the Tax Reform Act of 1986  eliminates
the  capital  gain deduction for tax years beginning after  December  31,
1986,  the  federal adjusted gross income, the computation base  for  the
Michigan  Income Tax, of a Unit Holder will be increased  accordingly  to
the  extent  such  capital  gains are realized when  the  Michigan  Trust
disposes of a Debt Obligation or when the Unit Holder redeems or sells  a
Unit,  to  the  extent such transaction constitutes a taxable  event  for
Federal income tax purposes.

Stone  under the heading "Michigan Tax Status" in the Prospectus relating

     Re:  Insured Municipals Income Trust, 165th Insured Multi-Series*

Dear Mr. Kneedy:
     
     Pursuant  to your request for a Standard & Poor's rating on the units  of
the  above-captioned  trust, SEC #33-55407, we have reviewed  the  information
presented to us and have assigned a 'AAA' rating to the units of the trust and
a  'AAA'  rating to the securities contained in the trust for as long as  they
remain in the trust.  The ratings are direct reflections, of the portfolio  of
the  trust,  which  will  be  composed solely of securities  covered  by  bond
insurance policies that insure against default in the payment of principal and
interest  on the securities so long as they remain in the trust.   Since  such
policies  have been issued by one or more insurance companies which have  been
assigned a 'AAA' claims paying ability rating by S&P, S&P has assigned a 'AAA'
rating to the units of the trust and to the securities contained in the  trust
for as long as they remain in the trust.
     
     You  have permission to use the name of Standard & Poor's Corporation and
the   above-assigned  ratings  in  connection  with  your   dissemination   of
information relating to these units, provided that it is understood  that  the
ratings are not "market" ratings nor recommendations to buy, hold, or sell the
units  of  the  trust or the securities contained in the trust.   Further,  it
should  be  understood the rating on the units does not take into account  the
extent  to  which  fund expenses or portfolio asset sales for  less  than  the
fund's  purchase price will reduce payment to the unit holders of the interest
and  principal required to be paid on the portfolio assets.  S&P reserves  the
right  to  advise its own clients, subscribers, and the public of the ratings.
S&P  relies on the sponsor and its counsel, accountants, and other experts for
the  accuracy and completeness of the information submitted in connection with
the  ratings.  S&P does not independently verify the truth or accuracy of  any
such information.
     
     This  letter evidences our consent to the use of the name of  Standard  &
Poor's Corporation in connection with the rating assigned to the units in  the
registration  statement  or prospectus relating to the  units  or  the  trust.
However,  this letter should not be construed as a consent by us,  within  the
meaning of Section 7 of the Securities Act of 1933, to the use of the name  of
Standard & Poor's Corporation in connection with the ratings assigned  to  the
securities contained in the trust.  You are hereby authorized to file  a  copy
of this letter with the Securities and Exchange Commission.
     
     Please  be  certain to send us three copies of your final  prospectus  as
soon  as it becomes available.  Should we not receive them within a reasonable
time  after the closing or should they not conform to the representations made
to us, we reserve the right to withdraw the rating.
     
     We  are pleased to have had the opportunity to be of service to you.   If
we can be of further help, please do not hesitate to call upon us.

                                    Sincerely,
