offering  prices of the securities in this Series and may vary materially
from that of the previous Series.

accepted  prior to the time the registration statement becomes effective.
This Prospectus shall not constitute an offer to sell or the solicitation
of  an offer to buy nor shall there be any sale of the Units in any state
in  which  such  offer, solicitation or sale would be unlawful  prior  to

INSURED MUNICIPALS INCOME TRUST, 154TH INSURED MULTI-SERIES

IM-IT 316
IM-IT 76th Intermediate
Colorado IM-IT 67
Connecticut IM-IT 23
Florida IM-IT 76
    
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, insured portfolio of tax-exempt bonds. The Fund
consists of five underlying separate unit investment trusts designated as
Insured Municipals Income Trust, Series 316 (the "IM-IT"), Insured Municipals
Income Trust, 76th Intermediate Series (the "IM-IT Intermediate Trust"),
Colorado Insured Municipals Income Trust, Series 67 (the "Colorado IM-IT
Trust"), Connecticut Insured Municipals Income Trust, Series 23 (the
"Connecticut IM-IT Trust") and Florida Insured Municipals Income Trust, Series
76 (the "Florida IM-IT Trust"). The various trusts are collectively referred
to herein as the "Trusts", the Colorado IM-IT, Connecticut IM-IT and Florida
IM-IT Trusts are sometimes collectively referred to herein as the "State
Trusts", while the IM-IT, IM-IT Intermediate, Colorado IM-IT, Connecticut
IM-IT and Florida 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 22. 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
opening of business on 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 at the
opening of business (except for the IM-IT as of 8:00 A.M. Central Time on the
Date of Deposit) on February 3, 1994, 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.

     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".

    Evaluations for purpose of sale, purchase or redemption of Units are made

<FN>
<F1>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.
<F2>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%).
<F3>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
 <PAGE>
4                 Summary of Essential Financial Information
    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."
<F4>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.

SETTLEMENT OF BONDS IN THE TRUSTS
   
     THE FUND. Insured Municipals Income Trust, 154th 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 five 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 and IM-IT Intermediate Trusts 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
 <PAGE>
8                          Unitholder Explanations
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.
 <PAGE>
                           Unitholder Explanations                           9

     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.

     PORTFOLIO CONCENTRATIONS. 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.

10                         Unitholder Explanations

     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
 <PAGE>
                           Unitholder Explanations                          11
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
 <PAGE>
12                         Unitholder Explanations
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
 <PAGE>
                           Unitholder Explanations                          13
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
 <PAGE>
14                         Unitholder Explanations
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 opening of business on 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-
 <PAGE>
                           Unitholder Explanations                          15
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

     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 February 10, 1994. The
first record date for each Trust (March 1, 1994) is 21 days from such date.
The daily rates of estimated net annual interest income per Unit are $.13699,
$.11900, $.12864, $.12818 and $.13082 for the IM-IT, IM-IT Intermediate,
Colorado IM-IT, Connecticut IM-IT and Florida IM-IT Trusts, respectively. This
amounts to $2.88, $2.50, $2.70, $2.69 and $2.75 for the IM-IT, IM-IT
Intermediate, Colorado IM-IT, Connecticut IM-IT and Florida 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 Colorado IM-IT Trust:

     The Colorado IM-IT Trust accrues

        $2.70 to the first record date plus

        $38.60 which is 10 normal distributions at $3.86, and finally adding

        $5.01 which has accrued from January 1, 1995 until February 10, 1995
              which completes the 360 day cycle (39 days times the daily
              factor)

     Total $46.31 interest earned / $1,000.00 (Date of Deposit Public Offering
                  Price) = 4.63% 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
 <PAGE>
16                         Unitholder Explanations
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. For purposes of computation, Bonds will be deemed to mature on their
expressed maturity dates unless: (a) the Bonds have been called for redemption
or funds or securities have been placed in escrow to redeem them on an earlier
call date, in which case such call date will be deemed to be the date upon
which they mature; or (b) such Bonds are subject to a "mandatory tender", in
which case such mandatory tender will be deemed to be the date upon which they
mature.
    
     The effect of this method of sales charge computation will be that
different sales charge rates will be applied to each Trust based upon the
dollar weighted average maturity of such Trust's Portfolio, in accordance with
the following schedule:

YEARS TO MATURITY         SALES CHARGE  YEARS TO MATURITY         SALES CHARGE
 1...................         1.523%    9....................         4.712%
 2...................         2.041     10...................         4.932

 4...................         3.199     12...................         4.932
 5...................         3.842     13...................         5.374
 6...................         4.058     14...................         5.374
 7...................         4.275     15...................         5.374
 8...................         4.493     16 to 30.............         6.045

     The sales charges in the above table are expressed as a percentage of the
aggregate bid prices of the Securities in 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:

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. To determine the applicable sales charge
for units purchased in accordance with (b) above, 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 opening of business on 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 opening of business on
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
 <PAGE>
18                         Unitholder Explanations
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
 <PAGE>
                           Unitholder Explanations                          19
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
 <PAGE>
20                         Unitholder Explanations
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
 <PAGE>
                           Unitholder Explanations                          21
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. 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
 <PAGE>
22                         Unitholder Explanations
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
 <PAGE>
                           Unitholder Explanations                          23
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".

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

     Municipal Bond Investors Assurance Corporation ("MBIA") is the principal
operating subsidiary of MBIA Inc., a New York Stock Exchange listed company.
MBIA Inc. is not obligated to pay the debts of or claims against MBIA. MBIA is
a limited liability corporation rather than a several liability association.
MBIA is domiciled in the State of New York and licensed to do business in all
fifty states, the District of Columbia and the Commonwealth of Puerto Rico. As
of December 31, 1992 MBIA had admitted assets of $2.6 billion (audited), total
liabilities of $1.7 billion (audited), and total capital and surplus of $896
million (audited) determined in accordance with statutory accounting practices
prescribed or permitted by insurance regulatory authorities. As of September
30, 1993, MBIA had admitted assets of $3.0 billion (unaudited), total
liabilities of $2.0 billion (uaudited), and total capital and surplus of $951
million (unaudited) determined in accordance with statutory accounting

Street, Armonk, New York 10504.

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

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

     Standard & 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.

23, 1985. Financial Security and its two wholly owned subsidiaries are
licensed to engage in the financial guaranty insurance business in 49 states,
the District of Columbia and Puerto Rico.

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

     Financial Security is 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

     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.

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

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

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

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

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

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

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

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

     In connection with the Sale, Holdings and CapMAC entered into an
Ownership Policy Agreement (the "Ownership Policy Agreement"), which sets
forth Holdings' intent with respect to its ownership and control of CapMAC and
provides for certain policies and agreements with respect to Holdings'
exercise of its control of CapMAC. In the Ownership Policy Agreement, Holdings
has agreed that, during the term of the Ownership Policy Agreement, it will
not, and will not permit any stockholder of Holdings to enter into any
transaction the result of which would be a change of control (as defined in
the Ownership Policy Agreement) of CapMAC, unless the long term debt
obligations or claims-paying ability of the person which would control CapMAC
after such transaction or its direct or indirect parent are rated in a high
investment grade category, unless Holdings or CapMAC has confirmed that
CapMAC's claims-paying ability rating by Moody's (the "Rating") in effect
immediately prior to any such change of control will not be downgraded by
Moody's upon such change of control or unless such change of control occurs as
a result of a public offering of Holdings' capital stock.

     In addition, the Ownership Policy Agreement includes agreements (i) not
to change the "zero-loss" underwriting standards or policies and procedures of
CapMAC in a manner that would materially and adversely affect the risk profile
of CapMAC's book of business, (ii) that CapMAC will adhere to the aggregate
leverage limitations and maintain capitalization levels considered by Moody's
from time to time as consistent with maintaining CapMAC's Rating and (iii)
that until CapMAC's statutory capital surplus and contingency reserve
("qualified statutory capital")
 <PAGE>
                           Unitholder Explanations                          27
equal $250 million, CapMAC will maintain a specified amount of qualified
statutory capital in excess of the amount of qualified statutory capital that
CapMAC is required at such time to maintain under the aggregate leverage
limitations set forth in Article 69 of the New York Insurance Law.

     The Ownership Policy Agreement will terminate on the earlier of the date
on which a change of control of CapMAC occurs and the date on which CapMAC and
Holdings agree in writing to terminate the Ownership Policy Agreement;
provided that, CapMAC or Holdings has confirmed that CapMAC's Rating in effect
immediately prior to any such termination will not be downgraded upon such
termination.

     As of December 31, 1992 and 1991, CapMAC had statutory capital and
surplus of approximately $148 million and $232 million, respectively, and had
not incurred any debt obligations. On June 26, 1992, CapMAC made a special
distribution (the "Distribution") to Holdings in connection with the Sale in
an aggregate amount that caused the total of CapMAC's statutory capital and
surplus to decline to approximately $150 million. Holdings applied
substantially all of the proceeds of the Distribution to repay debt owed to
Citicorp that was incurred in connection with the capitalization of CapMAC. As
of June 30, 1992, CapMAC had statutory capital and surplus of approximately
$150 million and had not incurred any debt obligations. In addition, at
December 31, 1992 CapMAC had a statutory contingency reserve of approximately
$15 million, which is also available to cover claims under surety bonds issued
by CapMAC. Article 69 of the New York State Insurance Law requires that CapMAC
establishes and maintains the contingency reserve.

     In addition to its capital (including contingency reserve) and other
reinsurance available to pay claims under its surety bonds, on June 25, 1992,
CapMAC entered into a Stop Loss Reinsurance Agreement (the "Stop Loss
Agreement") with Winterthur Swiss Insurance Company (the "Reinsurer"), which
is rated AAA by Standard & Poor's and Aaa by Moody's, pursuant to which the
Reinsurer will be required to pay any losses incurred by CapMAC during the
term of the Stop Loss Agreement on the surety bonds covered under the Stop
Loss Agreement in excess of a specified amount of losses incurred by CapMAC
under such surety bonds (such specified amount initially being $100 million
and increasing annually by an amount equal to 66 2/3% of the increase in
CapMAC's statutory capital and surplus) up to an aggregate limit payable under
the Stop Loss Agreement of $50 million. The Stop Loss Agreement has an initial
term of seven years, is extendable for one-year periods and is subject to
early termination upon the occurrence of certain events.

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

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

     In order to be in 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.
 <PAGE>

     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 Returns on the
Securities in the IM-IT, Colorado IM-IT Trust and Connecticut IM-IT Trust were
4.93%, 4.63% and 4.61%, respectively, after payment of the insurance premium
or premiums payable by each Trust, while the Estimated Long-Term Returns on
such Trusts were 4.95%, 4.58% and 4.65%, respectively. The Estimated Current
Returns on identical portfolios without the insurance obtained by the
above-mentioned Trusts would have been 4.95%, 4.65% and 4.66%, respectively,
on such date, while the Estimated Long-Term Returns on identical portfolios
without the insurance obtained by the above mentioned Trusts would have been
4.96%, 4.60% and 4.69%, respectively.
    
     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.

IM-IT

      GENERAL. The IM-IT consists of 12 issues of Securities. Two of the Bonds
in the IM-IT are general obligations of the governmental entities issuing them
and are backed by the taxing power thereof. The remaining issues are payable
from the income of a specific project or authority and are not supported by
the issuer's power to levy taxes. These issues are located in 10 states or
territories, divided by purpose of issues (and percentage of principal amount
to total IM-IT) as follows: Health Care, 2 (22%); Transportation, 2 (16%);
Single Family Mortgage Revenue, 1 (11%); Water and Sewer, 1 (11%); Wholesale
Electric, 1 (11%); Public Building, 1 (10%); General Obligations, 2 (7%);
Multi-Family Mortgage Revenue, 1 (7%) and Retail Electric/Gas, 1 (5%). 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.

<FN>
<F1> During the first year the Trustee will reduce its fee by approximately
     $.48 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 $51.29.
     Estimated Annual Expense per Unit (excluding insurance) will be increased
     to $1.81; 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 $9,207.

<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 <F1>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 <F2>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".

IM-IT INTERMEDIATE TRUST

      GENERAL. The IM-IT Intermediate Trust consists of 11 issues of
Securities. Three of the Bonds in the IM-IT Intermediate 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 located in 7 states or territories, divided by
purpose of issues (and percentage of principal amount to total IM-IT
Intermediate Trust) as follows: Health Care, 3 (32%); General Obligations, 3
(20%); General Purpose, 1 (15%); Water and Sewer, 1 (15%); Public Education, 1
(12%) and Certificates of Participation, 2 (6%). Two bond issues aggregating
approximately 30% of the aggregate principal amount of the Securities in the
Trust are obligations of issuers located in the State of Pennsylvania. No Bond
issue has received a provisional rating. All of the obligations in the IM-IT
Intermediate Trust mature within 5-15 years of the Date of Deposit. The dollar
weighted average maturity of the Bonds in the Trust is 10.0 years.

<F1> During the first year the Trustee will reduce its fee by approximately
     $.62 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
     $44.77. Estimated Annual Expense per Unit (excluding insurance) will be
     increased to $1.93; 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 $4,929.

     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 <F1>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 <F2>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".

COLORADO IM-IT TRUST

      GENERAL. The Colorado IM-IT Trust consists of 8 issues of Securities.
Two of the Bonds in the Colorado 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 Colorado IM-IT Trust) as follows: Health Care, 3 (35%); Industrial
Revenue, 1 (17%); Retail Electric/Gas, 1 (17%); Water and Sewer, 1 (17%) and
General Obligations, 2 (14%). No Bond issue has received a provisional rating.

     SPECIAL CONSIDERATIONS. The State Constitution requires that expenditures
for any fiscal year not exceed revenues for such fiscal year. By statute, the
amount of General Fund revenues available for appropriation is based upon
revenue estimates which, together with other available resources, must exceed
annual appropriations by the amount of the unappropriated reserve (the
"Unappropriated Reserve"). The Unappropriated Reserve requirement for fiscal
year 1991, 1992 and 1993 was set at 3%. For fiscal year 1992 and thereafter,
General Fund appropriations are also limited by statute to an amount equal to
the cost of performing certain required reappraisals of taxable property plus
an amount equal to the lesser of (i) five percent of Colorado personal income
or (ii) 106% of the total General Fund appropriations for the previous fiscal
year. This restriction does not apply to any General Fund appropriations which
are required as a result of a new federal law, a final state or federal court
order or moneys derived from the increase in the rate or amount of any tax or
fee approved by a majority of the registered electors of the State voting at
any general election. In addition, the statutory limit on the level of General
Fund appropriations may be exceeded for a given fiscal year upon the
declaration of a State fiscal emergency by the State General Assembly.

     The 1991 fiscal year end fund balance was $16.3 million, which was $62.8
million below the 3% Unappropriated Reserve requirement. As of the end of the
1992 fiscal year, the fund balance was $133.3 million, which was $49.1 million
over the 3% Unappropriated Reserve requirement. Based on June 20, 1993
estimates, the 1993 fiscal year ending fund balance is expected to be $281.8
million, or $189.7 million over the 3% required Unappropriated Reserve.

     On November 3, 1992, voters in Colorado approved a constitutional
amendment (the "Amendment") which, in general, became effective December 31,
1992, and which could restrict the ability of the State and local governments
to increase revenues and impose taxes. The Amendment applies to the State and
all local governments, including home rule entities ("Districts").
Enterprises, defined as government-owned businesses authorized to issue
revenue bonds and receiving under 10% of annual revenue in grants from all
Colorado state and local governments combined, are excluded from the
provisions of the Amendment.

     The provisions of the Amendment are unclear and will probably require
judicial interpretation. Among other provisions, beginning November 4, 1992,
the Amendment requires voter approval prior to tax increases, creation of
debt, or mill levy or valuation for assessment ratio increases. The Amendment
also limits increases in government spending and property tax revenues to
specified percentages. The Amendment requires that District property tax
revenues yield no more than the prior year's revenues adjusted for inflation,
voter approved changes and (except with regard to school districts) local
growth in property values according to a formula set forth in the Amendment.
School districts are allowed to adjust tax levies for changes in student
enrollment. Pursuant to the Amendment, local government spending is to be
limited by the same formula as the limitation for property tax revenues. The
Amendment limits increases in expenditures from the State general fund and
program revenues (cash funds) to the growth in inflation plus the percentage
change in State population in the prior calendar year. The basis for initial
spending and revenue limits are fiscal year 1992 spending and 1991 property
taxes collected in 1992. The basis for spending and revenue limits for fiscal
year 1994 and later years will be the prior fiscal year's spending and
property taxes collected in the prior calendar year. Debt service changes,
reductions and voter-approved revenue changes are excluded from the
calculation basis. The Amendment also prohibits new or increased real property
transfer tax rates, new State real property taxes and local District income
taxes.

     According to the Colorado Economic Prespective, Fourth Quarter, FY
1992-93, June 20, 1993 (the "Economic Report"), inflation for 1992 was 3.7%
and population grew at the rate of 2.7% in Colorado. Accordingly, under the
Amendment, increases in State expenditures during the 1994 fiscal year will be
limited to 6.4% over expenditures during the 1993 fiscal year. The 1993 fiscal
year is the base year for calculating the limitation for the 1994 fiscal year.
For the 1993 fiscal year, the Office of State Planning and Budgeting estimates
that general fund revenues will total $3,341.7 million and that program
revenues (cash funds) will total $1,753.4 million, or total estimated base
revenues of $5,095.1 million. Expenditures for the 1994 fiscal year,
therefore, cannot exceed $5,421.2 million. However, the
 <PAGE>
                          Colorado IM-IT-- Series 67                        35
1994 fiscal year general fund and program revenues (cash funds) are projected
to be only $5,220.4 million, or $200.8 million less than expenditures allowed
under the spending limitation.

     There is also a statutory restriction on the amount of annual increases
in taxes that the various taxing jurisdictions in Colorado can levy without
electoral approval. This restriction does not apply to taxes levied to pay
general obligation debt.

     As the State experienced revenue shortfalls in the mid-1980s, it adopted
various measures, including impoundment of funds by the Governor, reduction of
appropriations by the General Assembly, a temporary increase in the sales tax,
deferral of certain tax reductions and inter-fund borrowings. On a GAAP basis,
the State had unrestricted General Fund balances at June 30 of approximately
$100.3 million in fiscal year 1988, $134.4 million in fiscal year 1989, $116.6
million in fiscal year 1990, $16.3 million in fiscal year 1991 and $133.3
million in fiscal year 1992. The fiscal year 1993 unrestricted general fund is
currently estimated to be $281.8 million.

     For fiscal year 1992, the following tax categories generated the
following respective revenue percentages of the State's $2,995.8 million total
gross receipts: individual income taxes represented 53.7% of gross fiscal year
1992 receipts; excise taxes represented 33.4% of gross fiscal year 1992
receipts; and corporate income taxes represented 3.7% of gross fiscal year
1992 receipts. The final budget for fiscal year 1993 projects general fund
revenues of approximately $3,341.7 million and appropriations of approximately
$3,046.7 million. The percentages of general fund revenue generated by type of
tax for fiscal year 1993 are not expected to be significantly different from
fiscal year 1992 percentages.

     Under its constitution, the State of Colorado is not permitted to issue
general obligation bonds secured by the full faith and credit of the State.
However, certain agencies and instrumentalities of the State are authorized to
issue bonds secured by revenues from specific projects and activities. The
State enters into certain lease transactions which are subject to annual
renewal at the option of the State. In addition, the State is authorized to
issue short-term revenue anticipation notes. Local governmental units in the
State are also authorized to incur indebtedness. The major source of financing
for such local government indebtedness is an ad valorem property tax. In
addition, in order to finance public projects, local governments in the State
can issue revenue bonds payable from the revenues of a utility or enterprise
or from the proceeds of an excise tax, or assessment bonds payable from
special assessments. Colorado local governments can also finance public
projects through leases which are subject to annual appropriation at the
option of the local government. Local governments in Colorado also issue tax
anticipation notes. The Amendment requires prior voter approval for the
creation of any multiple fiscal year debt or other financial obligation
whatsoever, except for refundings at a lower rate or obligations of an
enterprise.

     Based on data published by the State of Colorado, Office of State
Planning and Budgeting as presented in the Economic Report, over 50% of
non-agricultural employment in Colorado in 1992 was concentrated in the retail
and wholesale trade and service sectors, reflecting the importance of tourism
to the State's economy and of Denver as a regional economic and transportation
hub. The government and manufacturing sectors followed as the fourth and fifth
largest employment sectors in the State, representing approximately 18.3% and
11.5%, respectively, of non-agricultural employment in the State in 1992.

     According to the Economic Report, during the first quarter of 1993,
45,900 net new jobs were generated in the Colorado economy, an increase of
24.4% over the first quarter of 1992. However, the unemployment rate rose from
an average of 5.5% during the first quarter of 1992 to 5.8% during the first
quarter of 1993. Total retail sales increased by 9.8% during the first quarter
of 1993 as compared to the same period in 1992.

     Personal income rose 6.6% in Colorado during 1992 and 5.5% in 1991. In
1992, Colorado was the twelfth fastest growing state in terms of personal
income growth. However, because of heavy migration into the state and a large
increase in low-paying retail sector jobs, per capita personal income in
Colorado increased by only 3.8% in 1992, 0.1% below the increase in per capita
personal income for the nation as a whole.

     Economic conditions in the State may have continuing effects on other
governmental units within the State (including issuers of the Bonds in the
Colorado IM-IT Trust), which, to varying degrees, have also experienced
reduced revenues as a result of recessionary conditions and other factors.

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

     Neither the Sponsor nor its counsel have independently examined the Bonds
to be deposited in and held in the Trust. However, although Chapman and Cutler
expresses no opinion with respect to the issuance of the Bonds, in rendering
its opinion expressed herein, it has assumed that: (i) the Bonds were validly
issued, (ii) the interest thereon
 <PAGE>
36                        Colorado IM-IT-- Series 67
is excludable from gross income for federal income tax purposes, and (iii)
interest on the Bonds, if received directly by a Unitholder, would be exempt
from the income tax imposed by the State that is applicable to individuals and
corporations (the "State Income Tax"). This opinion does not address the
taxation of persons other than full time residents of Colorado.

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

     Because Colorado income tax law is based upon the Federal law, the
Colorado IM-IT Trust is not an association taxable as a corporation for
purposes of Colorado income taxation.

     With respect to Colorado Unitholders, in view of the relationship between
Federal and Colorado tax computations described above:
     (1)   Each Colorado Unitholder will be treated as owning a pro rata share
        of each asset of the Colorado IM-IT Trust for Colorado income tax
        purposes in the proportion that the number of Units of such Trust held
        by the Unitholder bears to the total number of outstanding Units of
        the Colorado IM-IT Trust, and the income of the Colorado IM-IT Trust
        will therefore be treated as the income of each Colorado Unitholder
        under Colorado law in the proportion described;
     (2)   Interest on Bonds that would not be includable in income for
        Colorado income tax purposes when paid directly to a Colorado
        Unitholder will be exempt from Colorado income taxation when received
        by the Colorado IM-IT Trust and attributed to such Colorado Unitholder
        and when distributed to such Colorado Unitholder;
     (3)   Any proceeds paid under an insurance policy or policies issued to
        the Colorado IM-IT Trust with respect to the Bonds in the Colorado
        IM-IT Trust which represent maturing interest on defaulted obligations
        held by the Trustee will be excludable from Colorado adjusted gross
        income if, and to the same extent as, such interest would have been so
        excludable if paid in the normal course by the issuer of the defaulted
        obligations;
     (4)   Any proceeds paid under individual policies obtained by issuers of
        Bonds in the Colorado IM-IT Trust which represent maturing interest on
        defaulted obligations held by the Trustee will not be includable in
        income for Colorado income tax purposes if, and to the same extent as,
        such interest would not have been so includable if paid in the normal
        course by the issuer of the defaulted obligations;
     (5)   Each Colorado Unitholder will realize taxable gain or loss when the
        Colorado IM-IT Trust disposes of a Bond (whether by sale, exchange,
        redemption, or payment at maturity) or when the Colorado Unitholder
        redeems or sells Units at a price that differs from original cost as
        adjusted for amortization of bond discount or premium and other basis
        adjustments (including any basis reduction that may be required to
        reflect a Colorado Unitholder's share of interest, if any, accruing on
        Bonds during the interval between the Colorado Unitholder's settlement
        date and the date such Bonds are delivered to the Colorado IM-IT
        Trust, if later);
     (6)   Tax cost reduction requirements relating to amortization of bond
        premium may, under some circumstances, result in Colorado Unitholders
        realizing taxable gain when their Units are sold or redeemed for an
        amount equal to or less than their original cost; and
     (7)   If interest on indebtedness incurred or continued by a Colorado
        Unitholder to purchase Units in the Colorado IM-IT Trust is not
        deductible for federal income tax purposes, it also will be
        non-deductible for Colorado income tax purposes.

     Unitholders should be aware that all tax-exempt interest, including their
share of interest on the Bonds paid to the Colorado IM-IT Trust, is taken into
account for purposes of determining eligibility for the Colorado Property Tax/
Rent/Heat Rebate.

     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 $2,842.
<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 <F1>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 <F2>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".

CONNECTICUT IM-IT TRUST

      GENERAL. The Connecticut IM-IT Trust consists of 9 issues of Securities.
Five of the Bonds in the Connecticut 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 Connecticut IM-IT Trust) as follows: General
Obligations, 5 (36%); Health Care, 2 (34%); Single Family Mortgage Revenue, 1
(17%) and Transportation, 1 (13%). No Bond issue has received a provisional
rating.

     SPECIAL CONSIDERATIONS. Investors should be aware that manufacturing was
historically the most important economic activity within the State of
Connecticut but, in terms of number of persons employed, manufacturing has
declined in the last ten years while both trade and service-related industries
have become more important, and in 1992 manufacturing accounted for only 20.1%
of total non-agricultural employment in Connecticut. Defense-related business
represents a relatively high proportion of the manufacturing sector;
reductions in defense spending have already had a substantial adverse effect
on Connecticut's economy, and the State's largest defense contractors have
announced substantial planned labor force reductions scheduled to occur over
the next four years. Connecticut is now in a recession, the depth and duration
of which are uncertain. Moreover, while unemployment in the State as a whole
has generally remained below the national level, as of May 1993, the estimated
rate of unemployment in Connecticut on a seasonally adjusted basis was 7.4%,
compared to 6.9% for the United States as a whole, and certain geographic
areas in the State have been affected by high unemployment and poverty. The
State derives over 70% of its revenues from taxes imposed by it, the most
important of which have been the sales and use taxes and the corporation
business tax, each of which is sensitive to changes in the level of economic
activity in the State, but the Connecticut income tax on individuals, trusts,
and estates enacted in 1991 is expected to supersede each of them in
importance. There can be no assurance that general economic difficulties or
the financial circumstances of the State or its towns and cities will not
adversely affect the market value of the Bonds in the Connecticut IM-IT Trust
or the ability of the obligors to pay debt service on such Bonds.

     The General Fund budget adopted by Connecticut for the 1986-87 fiscal
year contemplated both revenues and expenditures of $4,300,000,000. The
General Fund ended the 1986-87 fiscal year with a surplus of $365,200,000. The
General Fund budget for the 1987-88 fiscal year contemplated General Fund
revenues and expenditures of $4,915,800,000. However, the General Fund ended
the 1987-88 fiscal year with a deficit of $115,600,000. The General Fund
budget adopted for the 1988-89 fiscal year anticipated that General Fund
expenditures of $5,551,000,000 and certain educational expenses of
$206,700,000 not previously paid through the General Fund would be funded in
part from surpluses of prior years and in part from higher tax revenues
projected to result from tax laws in effect for the 1987-88 fiscal year and
stricter enforcement thereof; a substantial deficit was projected during the
third quarter of the 1988-89 fiscal year, but largely because of tax law
changes that took effect before the end of the fiscal year, the deficit was
kept to $28,000,000. The General Fund budget adopted for the 1989-90 fiscal
year anticipated expenditures of approximately $6,224,500,000 and, by virtue
of tax increase legislation enacted to take effect generally at the beginning
of the fiscal year, revenues slightly exceeding such amount. However, largely
because of tax revenue shortfalls, the General Fund ended the 1989-90 fiscal
year with a deficit for the year of $259,500,000, wiping out reserves for such
events built up in prior years. The General Fund budget adopted for the
1990-91 fiscal year anticipated expenditures of $6,433,000,000, but no
significant new or increased taxes were enacted. Primarily because of
significant declines in tax revenues and unanticipated expenditures reflective
of economic adversity, the General Fund ended the 1990-91 fiscal year alone
with a further deficit of $809,000,000.

     A General Fund budget for the 1991-92 fiscal year was not enacted until
August 22, 1991. This budget anticipated General Fund expenditures of
$7,007,861,328 and revenues of $7,426,390,000. Projected decreases in revenues
resulting from a 25% reduction in the sales tax rate effective October 1,
1991, the repeal of the taxes on the capital gains and interest and dividend
income of resident individuals for years starting after 1991, and the
phase-out of the corporation business tax surcharge over two years commencing
with taxable years starting after 1991 were expected to be more than offset by
a new general income tax imposed at effective rates not to exceed 4.5% on the
Connecticut taxable income of resident and non-resident individuals, trusts,
and estates. The General Fund ended the 1991-92 fiscal year with an operating
surplus of $110,000,000. The General Fund budget for the 1992-93 fiscal year
anticipated General Fund expenditures of $7,372,062,859 and revenues of
$7,372,210,000. The General Fund ended the 1992-93 fiscal year with an
operating surplus of $113,500,000. Balanced General Fund budgets for the
biennium ending June 30, 1995, have been adopted appropriating expenditures of
$7,828,900,000 for the 1993-94 fiscal year and $8,266,000,000 for the 1994-95
fiscal year. In addition, expenditures of Federal, State and local funds
 <PAGE>
40                      Connecticut IM-IT-- Series 23
in the twelve years started July 1, 1984 for repair of the State's roads and
bridges now projected at $9,500,000,000 are anticipated, a portion of the
State's $4,100,000,000 share of which would be financed by bonds expected to
total $3,700,000,000 and by direct payments both of which would be supported
by a Special Transportation Fund first created by the General Assembly for the
1984-85 fiscal year.

     To fund operating cash requirements, prior to the 1991-92 fiscal year the
State borrowed up to $750,000,000 pursuant to authorization to issue
commercial paper and on July 29, 1991, it issued $200,000,000 of General
Obligation Temporary Notes, none of which temporary borrowings are currently
outstanding. To fund the cumulative General Fund deficit for the 1989-90 and
1990-91 fiscal years, the legislation enacted August 22, 1991, authorized the
State Treasurer to issue Economic Recovery Notes up to the aggregate amount of
such deficit, which must be payable no later than June 30, 1996; at least
$50,000,000 of such Notes, but not more than a cap amount, is to be retired
each fiscal year commencing with the 1991-92 fiscal year, and any
unappropriated surplus up to $205,000,000 in the General Fund at the end of
each of the three fiscal years commencing with the 1991-92 fiscal year must by
applied to retire such Notes as may remain outstanding at those times. On
September 25, 1991, and October 24, 1991, the State issued $640,710,000 and
$325,002,000, respectively, of such Economic Recovery Notes, of which
$630,610,000 was outstanding as of January 1, 1994.

     As a result of the State's budget problems, the ratings of its general
obligation bonds were reduced by Standard & Poor's from AA+ to AA on March 29,
1990, and by Moody's from Aa1 to Aa on April 9, 1990. Moreover, because of
these problems, on September 13, 1991, Standard & Poor's reduced its ratings
of the State's general obligation bonds and certain other obligations that
depend in part on the creditworthiness of the State to AA-. On March 7, 1991,
Moody's downgraded its ratings of the revenue bonds of four Connecticut
hospitals because of the effects of the State's restrictive controlled
reimbursement environment under which they have been operating.

     General obligation bonds issued by Connecticut municipalities are payable
primarily only from ad valorem taxes on property subject to taxation by the
municipality. Certain Connecticut municipalities have experienced severe
fiscal difficulties and have reported operating and accumulated deficits in
recent years. The most notable of these is the City of Bridgeport, which filed
a bankruptcy petition on June 7, 1991. The State opposed the petition. The
United States Bankruptcy Court for the District of Connecticut has held that
Bridgeport has authority to file such a petition but that its petition should
be dismissed on the grounds that Bridgeport was not insolvent when the
petition was filed. Regional economic difficulties, reductions in revenues,
and increased expenses could lead to further fiscal problems for the State and
its political subdivisions, authorities, and agencies. Difficulty in payment
of debt service on borrowings could result in declines, possibly severe, in
the value of their outstanding obligations and increases in their future
borrowing costs.

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

     The assets of the Connecticut IM-IT Trust will consist of obligations
(the "Bonds"); certain of the Bonds have been issued by or on behalf of the
State of Connecticut or its political subdivisions or other public
instrumentalities, state or local authorities, districts, or similar public
entities created under the laws of the State of Connecticut ("Connecticut
Bonds") and the balance of the Bonds have been issued by or on behalf of
entities classified for the relevant purposes as territories or possessions of
the United States, including one or more of Puerto Rico, Guam, or the Virgin
Islands, the interest on the obligations of which Federal law would prohibit
Connecticut from taxing if received directly by the Unitholders. Certain
Connecticut Bonds in the Connecticut IM-IT Trust were issued prior to the
enactment of the Connecticut income tax on the Connecticut taxable income of
individuals, trusts, and estates (the "Connecticut Income Tax"); therefore,
bond counsel to the issuers of such Bonds did not opine as to the exemption of
the interest on such Bonds from such tax. However, the Sponsor and special
counsel to the Trusts for Connecticut tax matters believe that such interest
will be so exempt. Interest on Bonds in the Connecticut IM-IT Trust issued by
other issuers, if any, is, in the opinion of bond counsel to such issuers,
exempt from state taxation.

     The Connecticut Income Tax was enacted in August, 1991. Generally, a
Unitholder recognizes gain or loss for purposes of this tax to the same extent
as he recognizes gain or loss for Federal income tax purposes. Ordinarily this
would mean that gain or loss would be recognized by a Unitholder upon the
maturity, redemption, sale, or other disposition by the Connecticut IM-IT
Trust of a Bond held by it, or upon the redemption, sale or other disposition
of a Unit of the Connecticut IM-IT Trust held by the Unitholder.

     However, on June 19, 1992, Connecticut legislation was adopted that
provides that gains and losses from the sale or exchange of Connecticut Bonds
held as capital assets will not be taken into account for purposes of the
Connecticut Income Tax for taxable years starting on or after January 1, 1992.
It is not clear whether this provision
 <PAGE>
                        Connecticut IM-IT-- Series 23                       41
would apply to gain or loss recognized by a Unitholder upon the maturity or
redemption of a Connecticut Bond held by the Connecticut IM-IT Trust or, to
the extent attributable to Connecticut Bonds held by the Connecticut IM-IT
Trust, to gain or loss recognized by a Unitholder upon the redemption, sale,
or other disposition of a Unit of the Connecticut IM-IT Trust held by the
Unitholder. Unitholders are urged to consult their own tax advisors concerning
these matters.

     In the opinion of Day, Berry & Howard, special counsel to the Fund for
Connecticut tax matters, which relies explicitly on the opinion of Chapman and
Cutler regarding Federal income tax matters, under existing Connecticut law:

         The Connecticut IM-IT Trust is not liable for any tax on or measured
    by net income imposed by the State of Connecticut.

         Interest income of the Connecticut IM-IT Trust from a Bond issued by
    or on behalf of the State of Connecticut, any political subdivision
    thereof, or public instrumentality, state or local authority, district, or
    similar public entity created under the laws of the State of Connecticut
    (a "Connecticut Bond"), or from a Bond issued by United States territories
    or possessions the interest on which Federal law would prohibit
    Connecticut from taxing if received directly by a Unitholder from the
    issuer thereof, is not taxable under the Connecticut tax on the
    Connecticut taxable income of individuals, trusts, and estates (the
    "Connecticut Income Tax"), when any such interest is received by the
    Connecticut IM-IT Trust or distributed by it to such a Unitholder.

         Insurance proceeds received by the Connecticut IM-IT Trust
    representing maturing interest on defaulted Bonds held by the Connecticut
    IM-IT Trust are not taxable under the Connecticut Income Tax if, and to
    the same extent as, such interest would not be taxable thereunder if paid
    directly to the Connecticut IM-IT Trust by the issuer of such Bonds.

         Gains and losses recognized by a Unitholder for Federal income tax
    purposes upon the maturity, redemption, sale, or other disposition by the
    Connecticut IM-IT Trust of a Bond held by the Connecticut IM-IT Trust or
    upon the redemption, sale, or other disposition of a Unit of the
    Connecticut IM-IT Trust held by a Unitholder are taken into account as
    gains or losses, respectively, for purposes of the Connecticut Income Tax,
    except that, in the case of a Unitholder holding a Unit of the Connecticut
    IM-IT Trust as a capital asset, such gains and losses recognized upon the
    sale or exchange of a Connecticut Bond held by the Connecticut IM-IT Trust
    are excluded from gains and losses taken into account for purposes of such
    tax and no opinion is expressed as to the treatment for purposes of such
    tax of gains and losses recognized upon the maturity or redemption of a
    Connecticut Bond held by the Connecticut IM-IT Trust or, to the extent
    attributable to Connecticut Bonds, of gains and losses recognized upon the
    redemption, sale, or other disposition by a Unitholder of a Unit of the
    Connecticut IM-IT Trust held by him.

         The portion of any interest income or capital gain of the Connecticut
    IM-IT Trust that is allocable to a Unitholder that is subject to the
    Connecticut corporation business tax is includable in the gross income of
    such Unitholder for purposes of such tax.

         An interest in a Unit of the Connecticut IM-IT Trust that is owned by
    or attributable to a Connecticut resident at the time of his death is
    includable in his gross estate for purposes of the Connecticut succession
    tax and the Connecticut estate tax.

<F2> The Estimated Current Return and Estimated Long-Term Return are increased

     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 <F1>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 <F2>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".

FLORIDA IM-IT TRUST

      GENERAL. The Florida IM-IT Trust consists of 9 issues of Securities.
None of the Bonds in the Florida IM-IT Trust are general obligations of the
governmental entities issuing them or are backed by the taxing power thereof.
All of the 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 Florida IM-IT Trust) as follows: Water and Sewer, 4 (43%); Health Care,
2 (34%); Retail Electric/Gas, 1 (9%); Certificates of Participation, 1 (8%)
and General Purpose, 1 (6%). No Bond issue has received a provisional rating.

     SPECIAL CONSIDERATIONS. Florida's economy has in the past been highly
dependent on the construction industry and construction related manufacturing.
This dependency has declined in recent years and continues to do so as a
result of continued diversification of the State's economy. For example, in
1980 total contract construction employment as a share of total non-farm
employment was just over seven percent and in 1990 the share had edged
downward to six percent. This trend is expected to continue as Florida's
economy continues to diversify. Florida, nevertheless, has a dynamic
construction industry with single and multi-family housing starts accounting
for 9.48% of total U.S. housing starts in 1991 while the State's population is
5.3% of the U.S. total population. Florida's housing starts since 1980 have
represented an average of 11.3% of the U.S.'s total annual starts, and except
for the recession years 1980-82, and the recession beginning in 1990, starts
have exceeded 160,000 a year.

     A driving force behind the State's construction industry has been the
State's rapid rate of population growth. Although Florida currently is the
fourth most populous state (with an estimated population of 13.4 million), its
annual population growth is now projected to decline as the number of people
moving into the State is expected to hover near the mid 200,000 range annually
well into the 1990s. This population trend should provide plenty of fuel for
business and home builders to keep construction activity lively in Florida for
some time to come. However, other factors do influence the level of
construction in the State. For example, Federal tax reform in 1986 and other
changes to the Federal income tax code have eliminated tax deductions for
owners of two or more residential real estate properties and have lengthened
depreciation schedules on investment and commercial properties. Economic
growth and existing supplies of commercial buildings and homes also contribute
to the level of construction activity in the State.

     Since 1980, the State's job creation rate is well over twice the rate for
the nation as a whole, and its growth rate in new non-agricultural jobs is the
fastest of the 11 most populous states and second only to California in the
absolute number of new jobs created. Contributing to the State's rapid rate of
growth in employment and income is international trade. Since 1980, the
State's unemployment rate has generally been below that of the U.S. Only in
the last two years has the State's unemployment rate moved ahead of the
national average. According to the U.S. Department of Commerce, the Florida
Department of Labor and Employment Security, and the Florida Consensus
Economic Estimating Conference (together the "Organization") the State's
unemployment rate was 8.2% during 1992. As of October 1993, the Organization
estimates that the unemployment rate will be 6.5% for 1993-94 and 6.0% in
1994-95. The State's two largest and fastest growing private employment
categories are the service and trade sectors. Together, they account for more
than 50% of the total non-farm employment growth between 1991-92 and 1992-93.
The service sector has overtaken the trade sector and is now the State's
largest employment category.

     Tourism is one of Florida's most important industries. Approximately 39.3
million tourists visited the State in 1991, as reported by the Florida
Department of Commence. In terms of business activities and state tax
revenues, tourists in Florida in 1991 represented an estimated 4.4 million
additional residents. Visitors to the State tend to arrive equally by air and
car. The State's tourism industry over the years has become more
sophisticated, attracting visitors year-round and, to a degree, reducing its
seasonality. Tourist arrivals should be slightly negatively impacted as a
result of Hurricane Andrew, but should recover and approximate in 1993-94 the
number expected prior to the storm. When the final numbers are in, it is
expected that by the end of the State's current fiscal year, 41.9 million
domestic and international tourists will have visited the State, up 7.8% from
the 39 million tourists that visited Florida in 1991-92. In 1993-94, tourist
arrivals should approximate 43.2 million.

                          Florida IM-IT-- Series 76                         45

     The State's per capita personal income in 1990 of $18,539 was slightly
below the national average of $18,696 and significantly ahead of that for the
southeast United States, which was $16,514. Growth in real personal income in
the State follows a course similar to that of the nation, increasing 0.3% in
1991-92 and increasing 2.7% in 1992-93. Real personal income in the State is
estimated to increase 3.7% in 1993-94 and 4.6% in 1994-95. Personal income was
affected by Hurricane Andrew, which should have some lingering effects. By the
end of 1994-95, real personal income per capita in the State is projected to
average 4.8% higher than its 1992-93 level.

     Compared to other states, Florida has a proportionately greater
retirement age population which comprises 18.3% (as of April 1, 1991) of the
State's population and is forecast to grow at an average annual rate of over
1.96% through the 1990s. Thus, property income (dividends, interest, and rent)
and transfer payments (Social Security and pension benefits, among other
sources of income) are a relatively more important source of income. For
example, Florida's total wages and salaries and other labor income in 1990 was
54.9% of total income, while a similar figure for the nation for 1990 was
64.8%. Transfer payments are typically less sensitive to the business cycle
than employment income and, therefore, act as stabilizing forces in weak
economic periods. While many of the U.S.'s senior citizens choose the State as
their place of retirement, the State is also recognized as attracting a
significant number of working age people. Since 1980, the prime working age
population (18-44) has grown at an average annual rate of 3.6%.

     In fiscal year 1991-92, approximately 64% of the State's total direct
revenue to its three operating funds was derived from State taxes, with
federal grants and other special revenue accounting for the balance. State
sales and use tax, corporate income tax, and beverage tax amounted to 68%, 7%
and 5%, respectively, of total receipts by the General Revenue Fund during
fiscal year 1991-92. In that same year, expenditures for education, health and
welfare, and public safety amounted to 53%, 30% and 13.3%, respectively, of
total expenditures from the General Revenue Fund.

     Hurricane Andrew left some parts of south Florida devastated.
Post-Hurricane Andrew clean up and rebuilding have changed the outlook for the
State's economy. Single and multi-family housing starts in 1993-94 are
projected to reach a combined level of 120,000, and to increase to 138,100
next year. Lingering recessionary effects on consumers and tight credit are
two of the reasons for relatively slow core construction activity, as well as
lingering effects from the 1986 tax reform legislation discussed above.
However, construction is one of the sectors most severely affected by
Hurricane Andrew. The construction figures above include additional housing
starts as a result of destruction by Hurricane Andrew. Total construction
expenditures are forecasted to increase 13.8% this year and increase 14.3%
next year.

     The State Constitution and statutes mandate that the State budget, as a
whole, and each separate fund within the State budget, be kept in balance from
currently available revenues each fiscal year. If the Governor or Comptroller
believes a deficit will occur in any State fund, by statute, he must certify
his opinion to the Administrative Commission, which then is authorized to
reduce all State agency budgets and releases by a suffficient amount to
prevent a deficit in any fund. Additionally, the State Constitution prohibits
issuance of State obligations to fund State operations.

     Estimated fiscal year 1992-93 General Revenue plus Working Capital funds
available total $13,554.8 million, an 8.2% increase over 1992-93. This
reflects a transfer of $190 million, out of an estimated $220.0 million in
non-recurring revenue due to Andrew, to a hurricane relief trust fund. Of the
total General Revenue plus Working Capital funds available to the State,
$12,959.2 million of that is Estimated Revenues (excluding the Andrew impact)
which represents an increase of 7.5% over the previous year's Estimated
Revenues. With effective General Revenues plus Working Capital Fund
appropriations at $13,276.9 million, unencumbered reserves at the end of
1993-94 are estimated at $277.9 million. Estimated, fiscal year 1994-95
General Revenue plus Working Capital funds available total $14,310.7 million,
a 5.6% increase over 1993-94. This amount reflects a transfer of $159.00
million in non-recurring revenue due to Hurricane Andrew, to a hurricane
relief trust fund. The $13,944.0 million in Estimated Revenues (excluding the
Hurricane Andrew impact) represent an increase of 7.6% over the previous
year's Estimated Revenues. The massive effort to rebuild and replace destroyed
or damaged property in the wake of Andrew is responsible for the substantial
positive revenue impacts shown here. Most of the impact is in the increase in
the State's sales tax.

46                        Florida IM-IT-- Series 76

     In fiscal year 1992-93, approximately 62% of the State's total direct
revenue to its three operating funds were derived from State taxes, with
Federal grants and other special revenue accounting for the balance. State
sales and use tax, corporate income tax, intangible personal property tax, and
beverage tax amounted to 68%, 7%, 4%, and 4%, respectively, of total General
Revenue Funds available during fiscal 1992-93. In that same year, expenditures
for education, health and welfare, and public safety amounted to approximately
49%, 30%, and 11%, respectively, of total expenditures from the General
Revenue Fund.

     The State's sales and use tax (6%) currently accounts for the State's
single largest source of tax receipts. Slightly less than 10% of the State's
sales and use tax is designated for local governments and is distributed to
the respective counties in which collected for such use by such counties and
the municipalities therein. In addition to this distribution, local
governments may (by referendum) assess a 0.5% or a 1.0% discretionary sales
tax within their county. Proceeds from this local option sales tax are
earmarked for funding local infrastructure programs and acquiring land for
public recreation or conservation or protection of natural resources as
provided under Florida law. Certain charter counties have other taxing powers
in addition, and non-consolidated counties with a population in excess of
800,000 may levy a local option sales tax to fund indigent health care. It
alone cannot exceed 0.5% and when combined with the infrastructure surtax
cannot exceed 1.0%. For the fiscal year ended June 30, 1992, sales and use tax
receipts (exclusive of the tax on gasoline and special fuels) totalled
$8,375.5 million, an increase of 2.7% over fiscal year 1990-91.

     The State imposes an alcoholic beverage wholesale tax (excise tax) on
beer, wine, and liquor. This tax is one of the State's major tax sources, with
revenues totalling $435.2 million in fiscal year ending June 30, 1992.
Alcoholic beverage tax receipts declined 1.0% over the previous year. The
revenues collected from this tax are deposited into the State's General
Revenue Fund.

     The second largest source of State tax receipts is the tax on motor
fuels. However, these revenues are almost entirely dedicated trust funds for
specific purposes and are not included in the State's General Revenue Fund.

     The State imposes a corporate income tax. All receipts of the corporate
income tax are credited to the General Revenue Fund. For the fiscal year ended
June 30, 1992, receipts from this source were $801.3 million, an increase of
14.2% from fiscal year 1990-91.

     The State also imposes a stamp tax on deeds and other documents relating
to realty, corporate shares, bonds, certificates of indebtedness, promissory
notes, wage assignments, and retail charge accounts. The documentary stamp tax
collections totaled $472.4 million during fiscal year 1991-92, a 0.5% increase
from the previous fiscal year. For the fiscal year 1990-91, 76.21% of the
documentary stamp tax revenues was deposited to the general Revenue Fund.
Beginning in fiscal year 1992-93, 71.29% of these taxes are to be deposited to
the General Revenue Fund.

     On January 12, 1988, the State began its own lottery. State law requires
that lottery revenues be distributed 50% to the public in prizes, 38% for use
in enhancing education, and the balance, 12.0% for costs of administering the
lottery. Fiscal year 1991-92 lottery ticket sales totalled $2.19 billion,
providing education with $835.4 million.

     The State's severance tax applies to oil, gas, and sulphur production, as
well as the severance of phosphate rock and other solid minerals. Total
collections from severance taxes total $67.2 million during fiscal year
1991-92, down 6.9% from the previous year. Beginning in fiscal year 1989-90,
60.0% of this amount was transferred to the General Revenue Fund. The 60.0%
allocation is expected to continue.

     At the end of fiscal 1992, approximately $4.52 billion in principal
amount of debt secured by the full faith and credit of the State was
outstanding. In addition, since July 1, 1992, the State issued about $274
million in principal amount of full faith and credit bonds.

     The State Constitution and statutes mandate that the State budget, as a
whole, and each separate fund within the State budget, be kept in balance from
currently available revenues each fiscal year. If the Governor or Comptroller
believe a deficit will occur in any State fund, by statute, he must certify
his opinion to the Administrative Commission, which then is authorized to
reduce all State agency budgets and releases by a sufficient amount to prevent
a deficit in any fund. Additionally, the State Constitution prohibits issuance
of State obligations to fund State operations.

     Currently under litigation are several issues relating to State actions
or State taxes that put at risk substantial amounts of General Revenue Fund
monies. Accordingly, there is no assurance that any of such matters,
individually or in the aggregate, will not have a material adverse affect on
Florida's financial position.

     In the wake of the U.S. Supreme Court decision holding that a Hawaii law
unfairly discriminated against out-of-state liquor producers, suits have been
filed in the State's courts contesting a similar State law (in effect prior to
1985) that seek $384 million in tax refunds. A trial court, in a ruling that
was subsequently upheld by the State's Supreme Court, found the State law in
question to be unconstitutional but made its ruling operate prospectively,
thereby denying any tax refunds. The issue of whether the unconstitutionality
of the tax should be applied retroactively was recently decided by the United
States Supreme Court. The Supreme Court found in favor of the taxpayers. On
remand from the U.S. Supreme Court, the Florida Supreme Court, on January 15,
1991, mandated further proceedings to fashion a "clear and certain remedy"
consistent with constitutional restrictions and the opinion of the U.S.
Supreme Court. The Florida Department of Revenue has proposed to the Florida
Supreme Court that the Department be allowed to collect back tax from those
who received a tax preference under the prior law. If the Department's
proposal is rejected and tax refunds are ordered to all potential claimants, a
liability of approximately $298 million could result. The case is now before
the Florida Circuit Court, Second Judicial District. That court will hear the
affected parties' response to the Department's proposed collection of the tax
at the higher rate charged to out-of-staters.

     Florida law provides preferential tax treatment to insurers who maintain
a home office in the State. Certain insurers challenged the constitutionality
of this tax preference and sought a refund of taxes paid. Recently, the State
Supreme Court ruled in favor of the State. Similar issues have been raised in
other cases where insurers have challenged taxes imposed on premiums received
for certain motor vehicle service agreements. These four cases and pending
refund claims total about $200 million.

     Florida maintains a bond rating of Aa and AA from Moody's Investors
Service and Standard & Poor's Corporation, respectively, on the majority of
its general obligation bonds, although the rating of a particular series of
revenue bonds relates primarily to the project, facility, or other revenue
sources from which such series derives funds for repayment. While these
ratings and some of the information presented above indicate that Florida is
in satisfactory economic health, there can be no assurance that there will not
be a decline in economic conditions or that particular Municipal Obligations
purchased by the Fund will not be adversely affected by any such changes.

     The sources for the information presented above include official
statements and financial statements of the State of Florida. While the Sponsor
has not independently verified this information, the Sponsor has no reason to
believe that the information is not correct in all material respects.

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

     The Bonds were accompanied by opinions of Bond Counsel to the respective
issuers thereof to the effect that the Bonds were exempt from the Florida
intangibles tax. Neither the Sponsor nor its counsel have independently
reviewed such opinions or examined the Bonds to be deposited in and held by
the Florida IM-IT Trust and have assumed the correctness as of the date of
deposit of the opinions of Bond Counsel.

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

           For Florida state income tax purposes, the Florida IM-IT Trust will
      not be subject to the Florida income tax imposed by Chapter 220, Florida
      Statutes. In addition, Florida does not impose any income taxes at the
      local level.

           Because Florida does not impose an income tax on individuals,
      non-corporate Unitholders residing in Florida will not be subject to any
      Florida income taxation on income realized by the Florida IM-IT Trust.
      Any amounts paid to the Florida IM-IT Trust or to non-corporate
      Unitholders residing in Florida under an insurance policy issued to the
      Florida IM-IT Trust or the Sponsor which represent maturing interest on
      defaulted obligations held by the Trustee will not be subject to the
      Florida income tax imposed by Chapter 220, Florida Statutes.

48                        Florida IM-IT-- Series 76

           Corporate Unitholders with commercial domiciles in Florida will be
      subject to Florida income or franchise taxation on income realized by
      the Florida IM-IT Trust and on payments of interest pursuant to any
      insurance policy. Other corporate Unitholders will be subject to Florida
      income or franchise taxation on income realized by the Florida IM-IT
      Trust (or on payments of interest pursuant to any insurance policy) only
      to the extent that the income realized does not constitute "non-business
      income" as defined by Chapter 220.

           Units will be subject to Florida estate tax only if held by Florida
      residents. However, the Florida estate tax is limited to the amount of
      the credit for state death taxes provided for in Section 2011 of the
      Internal Revenue Code.

           Neither the Bonds nor the Units will be subject to the Florida ad
      valorem property tax, the Florida intangibles personal property tax or
      Florida sales or use tax.

<F1> During the first year the Trustee will reduce its fee by approximately
     $.17 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
     $49.17. Estimated Annual Expense per Unit (excluding insurance) will be
     increased to $2.07; 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 $2,891.
<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 <F1>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 <F2>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".

 <PAGE>
50                           Notes to Portfolios

NOTES TO PORTFOLIOS:
   
AS OF THE DATE OF DEPOSIT: FEBRUARY 3, 1994
<FN>
<F1> 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 September 30, 1993 to February 3, 1994. These Securities
     have expected settlement dates ranging from February 3, 1994 to March 3,
     1994 (see "Unitholder Explanations").
    
<F2> 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".
<F3> 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 <F2>under "Other
     Matters--Federal Tax Status".
<F4> 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").
<F5> Other information regarding the Bonds in each Trust, as of the Date of
     Deposit, is as follows:

     The Sponsor may have entered into contracts which hedge interest rate
     fluctuations on certain Bonds in certain Portfolios. The cost of any such
     contracts and the corresponding gain or loss is included in the Cost to
     Sponsor.

                             Notes to Portfolios                            51

     Certain Securities in the Fund, if any, marked by a double asterisk (**),
     have been purchased on a "when, as and if issued" or "delayed delivery"
     basis. Interest on these Securities begins accruing to the benefit of
     Unitholders on their respective dates of delivery. Delivery is expected
     to take place at various dates after the First Settlement Date as
     follows:
   
                                            PERCENT OF

TRUST                                         AMOUNT            TO FIRST SETTLEMENT DATE
IM-IT...............................            21%                   6 to 23 days
IM-IT Intermediate..................            37%                   7 to 21 days
Colorado IM-IT......................            17%                      5 days
Connecticut IM-IT...................            0%                         --
Florida IM-IT.......................            23%                    5 to 7 days

     On the Date of Deposit, the offering side evaluations of the Securities
     in the IM-IT, IM-IT Intermediate, Colorado IM-IT, Connecticut IM-IT and
     Florida IM-IT Trusts were higher than the bid side evaluations of such
     Securities by 0.75%, 0.73%, 0.75%, 0.75% and 0.74%, 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".
<F6> 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 3%, 5%, 5%, 4% and 3%
     of the aggregate principal amount of the Securities in the IM-IT, IM-IT
     Intermediate Trust, Colorado IM-IT Trust, Connecticut IM-IT Trust and
     Florida IM-IT Trust, respectively, are "zero coupon" bonds, respectively.
    
<F7> The issuer of this Bond has sold or reserved the right to sell to third
     parties all or a portion of its right to call the Bond in accordance with
     the redemption provisions of the Bond. See "Unitholder
     Explanations--Settlement of Bonds in the Trusts--Bond Redemptions."

     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,
 <PAGE>

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, 1st Insured Multi-Series and subsequent series and to any other
unit investment trusts sponsored by the Sponsor for which the Evaluator
provides portfolio supervisory services in any calendar year exceed the
aggregate cost to the Evaluator of supplying such services in such year. In
addition, the Evaluator shall receive an annual evaluation fee as indicated
under "Summary of Essential Financial Information" for regularly evaluating
each Trust's portfolio. Both of the foregoing fees may be increased without
approval of the Unitholders by amounts not exceeding proportionate increases
under the category "All Services Less Rent of Shelter" in the Consumer Price
Index published by the United States Department of Labor or, if such category
is no longer published, in a comparable category. The Sponsor and the
Underwriters will receive sales commissions and may realize other profits (or
losses) in connection with the sale of Units and the deposit of the Securities
as described under "General--Sponsor and Underwriter Compensation" below.

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

     The duties of the Trustee are primarily ministerial in nature. It did not
participate in the selection of Bonds for the portfolios of any of the Trusts.

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

     Under the Trust Agreement, the Trustee or any successor trustee may
resign and be discharged of the trusts created by the Trust Agreement by
executing an instrument in writing and filing the same with the Sponsor. The
Trustee or successor trustee must mail a copy of the notice of resignation to
all Fund Unitholders then of record, not less than 60 days before the date
specified in such notice when such resignation is to take effect. The Sponsor
upon receiving notice of such resignation is obligated to appoint a successor
trustee promptly. If, upon such resignation, no successor trustee has been
appointed and has accepted the appointment within 30 days after notification,
the retiring Trustee may apply to a court of competent jurisdiction for the
appointment of a successor. The Sponsor may remove the Trustee and appoint a
successor trustee as provided in the Trust Agreement at any time with or
without cause. Notice of such removal and appointment shall be mailed to each
Unitholder by the Sponsor. Upon execution of a written acceptance of such
appointment by such successor trustee, all the rights, powers, duties and
obligations of
 <PAGE>
                             Trust Administration                           59
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.
 <PAGE>
60                           Trust Administration

     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,
 <PAGE>
                             Trust Administration                           61
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, a State Trust or a
National Quality 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 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 accrued interest computed
as described above under "Unitholder Explanations--Interest Earning
Schedule--Accrued Interest (Accrued Interest to Carry)". 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 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 $25.00 per Unit for less than 100 Units, $29.00 per Unit for any single
transaction of 100 to 249 Units, $28.50 per Unit for any single transaction of
250 to 499 Units, $31.50 per Unit for any single transaction of 500 to 999
Units and $31.00 per Unit for any single transaction of 1,000 or more Units of
an IM-IT Intermediate Trust, and in the case of an IM-IT, a State Trust or a
National Quality Trust, $30.00 per Unit for less than 100 Units, $36.00 per
Unit for any single transaction of 100 to 249 Units, $38.00 per Unit for any
single transaction of 250 to 499 Units, $39.00 per Unit for any single
transaction of 500 to 999 Units and $39.00 per Unit for any single transaction
of 1,000 or more Units, provided that such Units are acquired either from the
Sponsor (in the case of dealer transactions) or through the Sponsor (in the
case of transactions involving brokers or others). The increased concession or
agency commission is a result of the discount given to purchasers for quantity
purchases. See "Unitholder Explanations--Public Offering--General". Certain
commercial banks are making Units of the Fund available to their customers on
an agency basis. A portion of the sales charge paid by these customers (equal
to the agency commission referred to above) is retained by or remitted to the
banks. Under the Glass-Steagall Act, banks are prohibited from underwriting
Units of the Fund; however, the Glass-Steagall Act does permit certain agency
transactions and the banking regulators have not indicated that these
particular agency transactions are not permitted under such Act. In addition,
state securities laws on this issue may differ from the interpretations of
federal law expressed herein and banks and financial institutions may be
required to register as dealers pursuant to state law. Any quantity discount
(see "Unitholder Explanations-- Public Offering--General") provided to
investors will be borne by the selling dealer or agent. For secondary market
transactions, such concession or agency commission will amount to 70% of the
applicable sales charge as determined using the table found in "Unitholder
Explanations--Public Offering".
    
     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 Quality, IM-IT Limited Maturity, IM-IT Intermediate, IM-IT Short
Intermediate and other Insured Trusts, respectively, as of the Date of
Deposit. In connection with quantity sales to purchasers of any IM-IT, State
Trust or National Quality 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. In connection with quantity
sales to purchasers of any IM-IT Intermediate Trust the Underwriters will
receive from the Sponsor commissions totalling $30.00 per Unit for any single
transaction of 100 to 249 Units, $29.50 per Unit for any single transaction of
250 to 499 Units, $32.50 per Unit for any single transaction of 500 to 999
Units and $31.00 per Unit for any single transaction of 1,000 or more Units.
In addition, A. G. Edwards & Sons, Inc. ("Edwards"), which acts as a Managing
Underwriter of Units of the various series of the IM-IT and IM-IT Intermediate
Trusts, respectively, will receive from the Sponsor reimbursement for certain
costs and further compensation in the amount of $5.00 for each Unit it
underwrites of the IM-IT, and $3.00 for each Unit it underwrites of the IM-IT
Intermediate Trust, provided it underwrites a minimum of 1,500 Units of the
IM-IT Intermediate Trust. See "Unitholder Explanations--Public
Offering--General". 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
 <PAGE>
                             Trust Administration                           63
other series of the IM-IT and/or any series of the 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 Trusts it commits to underwrite in said month. In addition, the
Sponsor will receive from the Managing Underwriters of the Connecticut IM-IT
Trust (who underwrite 15% of the Trust involved or 1,000 Units of the Trust,
whichever is greater) the excess of such gross sales commission over $38.00
per Unit of the 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
the Connecticut IM-IT Trust will receive an additional $2.00 per each such
Unit. 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, Colorado and Florida tax law have been passed
upon by Chapman and Cutler, 111 West Monroe Street, Chicago, Illinois 60603,
as counsel for the Sponsor. Day, Berry & Howard has acted as special counsel
to the Fund for Connecticut 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; 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.

     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
 <PAGE>
                                Other Matters                               65
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
*As published by the rating companies.
 <PAGE>
68                              Other Matters
Aaa securities. These Aa bonds are high grade, their market value virtually
immune to all but money market influences, with the occasional exception of
oversupply in a few specific instances.

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

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

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

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

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

   To the Board of Directors of Van Kampen Merritt Inc. and the Unitholders
   of Insured Municipals Income Trust, 154th Insured Multi-Series (IM-IT,
   IM-IT Intermediate, Colorado IM-IT, Connecticut IM-IT and Florida IM-IT
   Trusts):

        We have audited the accompanying statements of condition and the
   related portfolios of Insured Municipals Income Trust, 154th Insured
   Multi-Series (IM-IT, IM-IT Intermediate, Colorado IM-IT, Connecticut
   IM-IT and Florida IM-IT Trusts) as of February 3, 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, 154th Insured Multi-Series (IM-IT, IM-IT
   Intermediate, Colorado IM-IT, Connecticut IM-IT and Florida IM-IT
   Trusts) as of February 3, 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 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

     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.

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.

</TABLE>

*The table takes into account the Connecticut income tax. The Connecticut
income tax is based on Connecticut taxable income, which is not
tied to Federal taxable income. Connecticut taxable income is equal to
Connecticut adjusted gross income ("CAGI") (which is Federal adjusted gross
income with certain modifications) minus the allowable personal exemption
($12,000 in the case of single individuals; $24,000 for married persons filing
jointly). Although not reflected in the table, the Connecticut income tax
provides for a personal exemption phase-out, which essentially doubles the
effective marginal Connecticut income tax rate for single taxpayers whose CAGI
is between $24,000 and $35,001 at which point the personal exemption is
completely phased out. For married taxpayers filing a joint return, the
effective marginal Connecticut income tax rate is doubled where CAGI is
between $48,000 and $71,001, at which point the personal exemption is
completely phased out. In addition, as reflected in the rates shown, the
Connecticut income tax provides for a tax credit (at varying percentages
depending on the taxpayer's CAGI) against the income tax which is based on
CAGI and, in effect, varies the income tax rate for taxpayers. Investors
should consult their own tax advisors regarding the effect of the credit on
marginal tax rates at specific CAGI levels.

*The State of Florida imposes no income tax on individuals; accordingly, the
table reflects only exemption from Federal income taxes. The table does not
reflect the exemption of Units of the Florida IM-IT Trust from the State's
intangible tax; accordingly, Florida residents subject to such tax would need
a somewhat higher taxable estimated current return than those shown to equal
the tax-exempt estimated current return of the Florida IM-IT Trust.
    
     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.
