INSURED MUNICIPALS INCOME TRUST AND

In the opinion of counsel, interest to the Fund and to Unitholders, with
certain exceptions, is excludable under existing law from gross income for
Federal income taxes. In addition, the interest income of each State Trust is,
in the opinion of counsel, exempt to the extent indicated from state and local
taxes, when held by residents of the state where the issuers of Bonds in such
Trust are located. Capital gains, if any, are subject to Federal tax.
   
      THE FUND.  The objectives of the Fund are Federal and, in the case of a
State Trust, state tax-exempt income and conservation of capital through an
investment in a diversified portfolio of tax-exempt bonds. The Fund consists
of seven underlying separate unit investment trusts designated as Insured
Municipals Income Trust, Series 325 (the "IM-IT"), Insured Municipals Income
Trust, 78th Intermediate Series (the "IM-IT Intermediate Trust"), New Mexico
Insured Municipals Income Trust, Series 14 (the "New Mexico IM-IT Trust"),
Pennsylvania Insured Municipals Income Trust, Series 187 (the "Pennsylvania
IM-IT Trust"), Kentucky Investors' Quality Tax-Exempt Trust, Series 51 (the
"Kentucky Quality Trust"), North Carolina Investors' Quality Tax-Exempt Trust,
Series 75 (the "North Carolina Quality Trust") and Oregon Investors' Quality
Tax-Exempt Trust, Series 52 (the "Oregon Quality Trust"). The various trusts
are collectively referred to herein as the "Trusts", the New Mexico IM-IT,
Pennsylvania IM-IT, Kentucky Quality, North Carolina Quality and Oregon
Quality Trusts are sometimes collectively referred to herein as the "State
Trusts", while the IM-IT, IM-IT Intermediate, New Mexico IM-IT and
Pennsylvania IM-IT Trusts are sometimes collectively referred to herein as the
"Insured Trusts" and the Kentucky Quality, North Carolina Quality and Oregon
Quality Trusts are sometimes collectively referred to herein as the "Quality
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 ONLY.  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
close of business on the day before the Date of Deposit (except for the IM-IT
and the Pennsylvania IM-IT Trust as of 8:00 A.M. Central Time on the Date of
Deposit), the Public Offering Price per Unit would have been that amount set
forth in the "Summary of Essential Financial Information" for each Trust.
See "Unitholder Explanations--Public Offering".
    
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

      ESTIMATED CURRENT RETURN AND ESTIMATED LONG-TERM RETURN. The annual
Estimated Current Return and Estimated Long-Term Return to Unitholders as of
the close of business (except for the IM-IT and the Pennsylvania IM-IT Trust
as of 8:00 A.M. Central Time on the Date of Deposit) on the day before the
Date of Deposit were as set forth under "Per Unit Information" for each
Trust. The methods of calculating Estimated Current Return and Estimated
Long-Term Return are set forth in the footnotes to the "Per Unit Information"
for each Trust.
    
     OBJECTIVES OF THE FUND. The objectives of the Fund are income exempt from
Federal income tax and, in the case of a State Trust, Federal and state income
tax (if any) and conservation of capital through an investment in diversified
portfolios of Federal and state tax-exempt obligations. There is, of course,
no guarantee that the Fund will achieve its objectives. The Fund may be an
appropriate investment vehicle for investors who desire to participate in a
portfolio of tax-exempt fixed income securities with greater diversification
than they might be able to acquire individually. In addition, securities of
the type deposited in the Fund are often not available in small amounts.

     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

<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
 <PAGE>

    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 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 and Investors' Quality
Tax-Exempt Trust, Multi-Series 221 (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 seven 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
 <PAGE>
8                          Unitholder Explanations
dates of delivery. To the extent any Securities are actually delivered to the
Fund after their respective expected dates of delivery, Unitholders who
purchase their Units prior to the date such Securities are actually delivered
to the Trustee would be required to adjust their tax basis in their Units for
a portion of the interest accruing on such Securities during the interval
between their purchase of Units and the actual delivery of such Securities. As
a result of any such adjustment, the Estimated Current Returns during the
first year would be slightly lower than those stated herein which would be the
returns after the first year, assuming the portfolio of a Trust and estimated
annual expenses other than that of the Trustee (which may be reduced in the
first year only) do not vary from that set forth under "Per Unit Information"
for the applicable Trust. Holders of the Units will be "at risk" with respect
to all Securities in the portfolios including "when, as and if issued" and
"delayed delivery" Securities (i.e., may derive either gain or loss from
fluctuations in the evaluation of such Securities) from the date they commit
for Units. For a discussion of the Sponsor's obligations in the event of the
failure of any contract for the purchase of any of the Securities and limited
right to substitute other tax-exempt bonds to replace any failed contract, see
"Replacement Bonds" below.

     Each Unit initially offered represents the fractional undivided interest
in the principal and net income of a Trust indicated under "Summary of
Essential Financial Information". To the extent that any Units are redeemed by
the Trustee, the fractional undivided interest in a Trust represented by each
unredeemed Unit will increase, although the actual interest in such Trust
represented by such fraction will remain unchanged. Units will remain
outstanding until redeemed upon tender to the Trustee by Unitholders, which
may include the Sponsor or the Underwriters, or until the termination of the
Trust Agreement.

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

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

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

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

     In selecting Securities for the Trusts the following facts, among others,
were considered by the Sponsor: (a) either the Standard & Poor's Corporation
rating of the Securities was in no case less than "BBB-" in the case of the
Insured Trusts and "A-" in the case of the Quality 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 and "A" in the case of the Quality
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 and "A-" or better in the case of the Quality Trusts by Standard &
Poor's Corporation or "Baa" or better in the case of the Insured Trusts and
"A" or better in the case of the Quality 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
 <PAGE>
14                         Unitholder Explanations
of the project to be financed with the proceeds of the Bonds resulting in
excess proceeds of the Bonds which may be applied to redeem Bonds; or an
underestimate of a source of funds securing the Bonds resulting in excess
funds which may be applied to redeem Bonds. The issuer of certain Bonds in a
Trust may have sold or reserved the right to sell, upon the satisfaction of
certain conditions, to third parties all or any portion of its rights to call
Bonds in accordance with the stated redemption provisions of such Bonds. In
such a case the issuer no longer has the right to call the Bonds for
redemption unless it reacquires the rights from such third party. A third
party pursuant to these rights may exercise the redemption provisions with
respect to a Bond at a time when the issuer of the Bond might not have called
a Bond for redemption had it not sold such rights. The Sponsor is unable to
predict all of the circumstances which may result in such redemption of an
issue of Bonds. See "Portfolio" for each Trust and footnote (3) in the "Notes
to Portfolios". See also the discussion of single family mortgage and
multi-family revenue bonds above for more information on the call provisions
of such bonds.

     DISTRIBUTIONS. Distributions of interest received by the Fund, pro rated
on an annual basis, will be made monthly. The first such distribution will be
in the amount indicated under 'Per Unit Information' for the applicable Trust
and will be made on the fifteenth day of the month indicated under "Initial
Distribution" therein to Unitholders of record on the first day of such month.
Distribution of funds from the Principal Account, if any, will also be made
monthly, except under certain special circumstances (see "Unitholder
Explanations--Public Offering--Distributions of Interest and Principal").

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

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

ESTIMATED CURRENT RETURNS AND ESTIMATED LONG-TERM RETURNS
   
     As of the close of business on the day before the Date of Deposit
(except for the IM-IT and the Pennsylvania IM-IT Trust 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
 <PAGE>
                           Unitholder Explanations                          15
the future. The Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of Estimated Long-Term Return
reflects the estimated date and amount of principal returned while the
Estimated Current Return calculation includes only net annual interest income
and Public Offering Price.
    
     In order to acquire certain of the Securities contracted for by the
Sponsor for deposit in the Fund, it may be necessary for the Sponsor or
Trustee to pay on the settlement dates for delivery of such Securities amounts
covering accrued interest on such Securities which exceed (1) the amounts paid
by Unitholders and (2) the amounts which will be made available through cash
furnished by the Sponsor on the Date of Deposit, which amount of cash may
exceed the interest which would accrue to the First Settlement Date. The
Trustee has agreed to pay for any amounts necessary to cover any such excess
and will be reimbursed therefor, without interest, when funds become available
from interest payments on the particular Securities with respect to which such
payments may have been made. Also, since interest on any "when, as and if
issued" Securities does not begin accruing as tax-exempt interest income to
the benefit of Unitholders until their respective dates of delivery, the
Trustee may, in order to maintain (or in some cases approach) for the
Unitholders the same estimated net annual interest incomes during the first
year of the Trusts' operations as is indicated under "Per Unit Information"
for the applicable Trust, reduce its fee (and to the extent necessary pay
Trust expenses) in an amount equal to that indicated under "Per Unit
Information" for the applicable Trust.

INTEREST EARNING SCHEDULE
   
     CALCULATION OF ESTIMATED NET ANNUAL INTEREST INCOME. The estimated net
annual interest income is based on 360 days. To account for the estimated net
annual interest income per Unit in a Trust, it is necessary to use the
following information.

     The beginning interest date for each Trust is May 26, 1994. The first
record date for each Trust (July 1, 1994) is 35 days from such date. The daily
rates of estimated net annual interest income per Unit are $.15889, $.14226,
$.15416, $.15648, $.15782, $.15482 and $.15059 for the IM-IT, IM-IT
Intermediate, New Mexico IM-IT, Pennsylvania IM-IT, Kentucky Quality, North
Carolina Quality and Oregon Quality Trusts, respectively. This amounts to
$5.56, $4.98, $5.40, $5.48, $5.52, $5.42 and $5.27 for the IM-IT, IM-IT
Intermediate, New Mexico IM-IT, Pennsylvania IM-IT, Kentucky Quality, North
Carolina Quality and Oregon Quality Trusts, respectively.

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

     The New Mexico IM-IT Trust accrues
        $5.40 to the first record date plus
        $46.20 which is 10 normal distributions at $4.62, and finally adding
        $3.89 which has accrued from May 1, 1995 until May 26, 1995 which

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
 <PAGE>
16                         Unitholder Explanations
First Settlement Date, the Public Offering Price of Units will have added to
it the proportionate share of accrued interest to the date of settlement.
Unitholders will receive on the next distribution date of the Trust the
amount, if any, of accrued interest paid on their Units.

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

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

PUBLIC OFFERING
   
     GENERAL. Units are offered at the Public Offering Price which includes
Purchased Interest. During the initial offering period the Public Offering
Price is based on the offering prices of the Securities in each Trust and
includes a sales charge of 4.9% of the Public Offering Price (excluding
Purchased Interest) (5.152% of the aggregate offering price of the Securities)
for an IM-IT or a State Trust, 4.3% of the Public Offering Price (excluding
Purchased Interest) (4.493% of the aggregate offering price of the Securities)
for an IM-IT Limited Maturity Trust, 3.9% of the Public Offering Price
(excluding Purchased Interest) (4.058% of the aggregate offering price of the
Securities) for an IM-IT Intermediate Trust and 3.0% of the Public Offering
Price (excluding Purchased Interest) (3.093% of the aggregate offering price
of the Securities) for an IM-IT Short Intermediate Trust. After the initial
public offering period, the secondary market Public Offering Price is based on
the bid prices of the Securities in each Trust and includes a sales charge
determined in accordance with the table set forth below, which is based upon
the dollar weighted average maturity of each Trust plus in each case Purchased
Interest. 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:

     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

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. In the event units of more than one trust
are purchased on the Initial Purchase Date, the aggregate dollar amount of
such purchases will be used to determine whether purchasers are eligible for a
reduced sales charge. Such aggregate dollar amount will be divided by the
public offering price per unit (on the day preceding the date of purchase) of
each respective trust purchased to determine the total number of units which
such amount could have purchased of each individual trust. Purchasers must
then consult the applicable trust's prospectus to determine whether the total
number of units which could have been purchased of a specific trust would have
qualified for a reduced sales charge and, if so qualified, the amount of such
reduction. Assuming a purchaser qualifies for a sales charge reduction or
reductions, to determine the applicable sales charge reduction or reductions
it is necessary to accumulate all purchases made on the Initial Purchase Date
and all purchases made in accordance with (b) above. Units purchased in the
name of the spouse of a purchaser or in the name of a child of such purchaser
under 21 years of age will be deemed for the purposes of calculating the
applicable sales charge to be additional purchases by the purchaser. The
reduced sales charges will also be applicable to a trustee or other fiduciary
purchasing securities for one or more trust estate or fiduciary accounts.
Employees of Van Kampen Merritt Inc. and its subsidiaries may purchase Units
of the Trust at the current Public Offering Price less the underwriting
commission during the initial offering period, and less the dealer's
concession for secondary market transactions. Registered representatives of
selling Underwriters may purchase Units of the Fund at the current Public
Offering Price less the underwriting commission during the initial offering
period, and less the dealer's concession for secondary market transactions.
Registered representatives of selling brokers, dealers, or agents may purchase
Units of the Fund at the current Public Offering Price less the dealer's
concession during the initial offering period and for secondary market
transactions.

     OFFERING PRICE. Public Offering Price of the Units will vary from the
amounts stated under "Summary of Essential Financial Information" in
accordance with fluctuations in the prices of the underlying Securities in
each Trust.
   
     As indicated above, the price of the Units as of the date the Securities
were deposited in each Trust was determined by adding to the aggregate
offering price of the Securities of a Trust an amount equal to the applicable
sales charge expressed as a percentage of the aggregate offering price of the
Securities plus Purchased Interest and dividing the sum so obtained by the
number of Units outstanding. This computation produced a gross underwriting
commission equal to such sales charge expressed as a percentage of the Public
Offering Price (excluding Purchased Interest). Such price determination as of
the close of business on the day before the Date of Deposit (except for the
IM-IT and the Pennsylvania IM-IT Trust 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
 <PAGE>
18                         Unitholder Explanations
for the IM-IT and the Pennsylvania IM-IT Trust as of 8:00 A.M. Central Time on
the Date of Deposit) and during the period of initial offering, the Evaluator
will appraise or cause to be appraised daily the value of the underlying
Securities of each Trust as of 4:00 P.M. Eastern time on days the New York
Stock Exchange is open for business and will adjust the Public Offering Price
of the Units commensurate with such appraisal. Such Public Offering Price will
be effective for all orders received at or prior to 4:00 P.M. Eastern time on
each such day. Orders received by the Trustee, Sponsor or any Underwriter for
purchases, sales or redemptions after that time, or on a day when the New York
Stock Exchange is closed, will be held until the next determination of price.
For secondary market sales the Public Offering Price per Unit will be equal to
the aggregate bid price of the Securities in the Trust plus an amount equal to
the applicable secondary market sales charge expressed as a percentage of the
aggregate bid price of the Securities plus Purchased Interest and dividing the
sum so attained by the number of Units then outstanding. This computation
produces a gross commission equal to such sales charge expressed as a
percentage of the Public Offering Price (excluding Purchased Interest). For
secondary market purposes such appraisal and adjustment with respect to a
Trust will be made by the Evaluator as of 4:00 P.M. Eastern time on days in
which the New York Stock Exchange is open for each day on which any Unit of
such Trust is tendered for redemption, and it shall determine the aggregate
value of any Trust as of 4:00 P.M. Eastern time on such other days as may be
necessary.
    
     The aggregate price of the Securities in each Trust has been and will be
determined on the basis of bid prices or offering prices, as is appropriate,
(a) on the basis of current market prices for the Securities obtained from
dealers or brokers who customarily deal in bonds comparable to those held by
the Fund; (b) if such prices are not available for any particular Securities,
on the basis of current market prices for comparable bonds; (c) by causing the
value of the Securities to be determined by others engaged in the practice of
evaluation, quoting or appraising comparable bonds; or (d) by any combination
of the above. Market prices of the Securities will generally fluctuate with
changes in market interest rates. Unless Bonds are in default in payment of
principal or interest or in significant risk of such default, the Evaluator
will not attribute any value to the insurance obtained by an Insured Trust, if
any.

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

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

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

     Although payment is normally made five business days following the order
for purchase, payment may be made prior thereto. A person will become the
owner of Units on the date of settlement provided payment has been received.
Cash, if any, made available to the Sponsor prior to the date of settlement
for the purchase of Units may be used in the Sponsor's business and may be
deemed to be a benefit to the Sponsor, subject to the limitations of the
Securities Exchange Act of 1934. Delivery of certificates representing Units
so ordered will be made five business days following
 <PAGE>
                           Unitholder Explanations                          19
such order or shortly thereafter. See "Redemption of Units" below for
information regarding the ability to redeem Units ordered for purchase.

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

     DISTRIBUTIONS OF INTEREST AND PRINCIPAL. Interest received by the Fund,
including that part of the proceeds of any disposition of Securities which
represents Purchased Interest and/or accrued interest, is credited by the
Trustee to the Interest Account for the appropriate Trust. Other receipts are
credited to the Principal Account for the appropriate Trust. Interest received
by the Fund after deduction of amounts sufficient to reimburse the Trustee,
without interest, for any amounts advanced and paid to the Sponsor as the
Unitholder of record as of the First Settlement Date (see "Public
Offering--Offering Price" above) will be distributed on or shortly after the
fifteenth day of each month on a pro rata basis to Unitholders of record of a
Trust as of the preceding record date who are entitled to distributions at
that time. All distributions will be net of applicable expenses. The pro rata
share of cash in the Principal Account of a Trust will be computed as of the
date set forth under "Per Unit Information" for the applicable Trust, and
thereafter as of the record date, and distributions to the Unitholders as of
such record date will be made on or shortly after the fifteenth day of such
month. Proceeds received from the disposition of any of the Securities after
such record date and prior to the following distribution date will be held in
the Principal Account and not distributed until the next distribution date.
The Trustee is not required to pay interest on funds held in any Principal or
Interest Account (but may itself earn interest thereon and therefore benefits
from the use of such funds) nor to make a distribution from the Principal
Account unless the amount available for distribution therein shall equal at
least $1.00 per Unit.

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

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

     REINVESTMENT OPTION. Unitholders of all unit investment trusts sponsored
by Van Kampen Merritt Inc. (except Unitholders of a New York IM-IT Trust or a
New York IM-IT Intermediate Laddered Maturity Trust), may elect to have each
distribution of interest income, capital gains and/or principal on their Units
automatically reinvested in shares of any of the open ended mutual funds
(except for B shares) listed under "Trust Administration--Sponsor" which are
registered in the Unitholder's state of residence. New York IM-IT Trust and
New York IM-IT Intermediate Laddered Maturity Trust Unitholders, other than
those residing in the Commonwealth of Massachusetts, may elect to have each
distribution of interest income, capital gains and/or principal on their Units
automatically reinvested in shares of First Investors New York Insured Tax
Free Fund, Inc., a fund which invests primarily in securities exempt from
federal and New York state and city income tax. Such mutual funds are
hereinafter collectively referred to as the "Reinvestment Funds".

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

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

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

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

     REDEMPTION OF UNITS. A Unitholder may redeem all or a portion of his
Units by tender to the Trustee, at its Unit Investment Trust Division, 101
Barclay Street, 20th Floor, New York, New York 10286, of the certificates
representing the Units to be redeemed, duly endorsed or accompanied by proper
instruments of transfer with signature guaranteed (or by providing
satisfactory indemnity, as in connection with lost, stolen or destroyed
certificates) and by payment of applicable governmental charges, if any. Thus,
redemption of Units cannot be effected until certificates representing such
Units have been delivered to the person seeking redemption or satisfactory
indemnity provided. No redemption fee will be charged. On the seventh calendar
day following such tender, or if the seventh calendar day is not a business
day, on the first business day prior thereto, the Unitholder will be entitled
to receive in cash an amount for each Unit equal to the Redemption Price per
Unit next computed after receipt by the Trustee of such tender of Units. The
"date of tender" is deemed to be the date on which Units are received by the
Trustee, except that as regards Units received after 4:00 P.M. Eastern time on
days of trading on the New York Stock Exchange, the date of tender is
 <PAGE>
                           Unitholder Explanations                          21
the next day on which such Exchange is open for trading and such Units will be
deemed to have been tendered to the Trustee on such day for redemption at the
Redemption Price computed on that day.

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

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

     The Redemption Price per Unit (as well as the secondary market Public
Offering Price) will be determined on the basis of the bid price of the
Securities in each Trust, while the initial and primary Public Offering Price
of Units will be determined on the basis of the offering price of the
Securities in each Trust, as of 4:00 P.M. Eastern time on days of trading on
the New York Stock Exchange on the date any such determination is made. On the
Date of Deposit the Public Offering Price per Unit (which is based on the
offering prices of the Bonds and Purchased Interest in each Trust and includes
the sales charge) exceeded the value at which Units could have been redeemed
(based upon the current bid prices of the Securities and Purchased Interest in
such Trust) by the amount shown under "Summary of Essential Financial
Information". While the Trustee has the power to determine the Redemption
Price per Unit when Units are tendered for redemption, such authority has been
delegated to the Evaluator which determines the price per Unit on a daily
basis. The Redemption Price per Unit is the pro rata share of each Unit in
each Trust on the basis of (i) the cash on hand in such Trust or moneys in the
process of being collected, (ii) the value of the Securities in such Trust
based on the bid prices of the Securities therein, except for cases in which
the value of insurance has been included, (iii) Purchased Interest for each
Trust and (iv) interest accrued thereon, less (a) amounts representing taxes
or other governmental charges payable out of such Trust and (b) the accrued
expenses of such Trust. The Evaluator may determine the value of the
Securities in each Trust by employing any of the methods set forth in "Public
Offering--Offering Price". In determining the Redemption Price per Unit no
value will be assigned to the portfolio insurance maintained on the Bonds in
an Insured Trust unless such Bonds are in default in payment of principal or
interest or in significant risk of such default. For a description of the
situations in which the Evaluator may value the insurance obtained by the
Insured Trusts, see "Public Offering--Offering Price" above.

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

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

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

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

INSURANCE ON THE BONDS IN THE INSURED TRUSTS

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

     The aforementioned portfolio insurance obtained by an Insured Trust, if
any, guarantees the timely payment of principal and interest on the Bonds as
they fall due. For the purposes of insurance obtained by an Insured Trust,
"when due" generally means the stated maturity date for the payment of
principal and interest. However, in the event (a) an issuer of a Bond defaults
in the payment of principal or interest on such Bond, (b) such issuer enters
into a bankruptcy proceeding or (c) the maturity of such Bond is accelerated,
the affected Portfolio Insurer has the option, in its sole discretion, after
receiving notice of the earliest to occur of such a default, bankruptcy
proceeding or acceleration to pay the outstanding principal amount of such
Bond plus accrued interest to the date of such payment
 <PAGE>
                           Unitholder Explanations                          23
and thereby retire the Bond from the affected Trust prior to such Bond's
stated maturity date. The insurance does not guarantee the market value of the
Bonds or the value of the Units. Insurance obtained by an Insured Trust, if
any, is only effective as to Bonds owned by and held in such Trust. In the
event of a sale of any such Bond by the Trustee, such insurance terminates as
to such Bond on the date of sale.

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

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

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

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

     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

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.

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

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

8.4% owned by The Tokio Marine and Fire Insurance Co., Ltd. ("Tokio Marine").
Neither U S WEST, Inc. nor Tokio Marine is obligated to pay the debts of or
the claims against Financial Security. Financial Security is domiciled in the
State of New York and is subject to regulation by the State of New York
Insurance Department. As of March 31, 1993, the total policyholders' surplus
and contingency reserves and the total unearned premium reserve, respectively,
of Financial Security and its consolidated subsidiaries were, in accordance

     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.

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

     CapMAC's claims-paying ability is rated "Aaa" by Moody's Investors
Service, Inc. ("Moody's"), "AAA" by Standard & Poor's Corporation ("Standard &
Poor's"), "AAA" by Duff & Phelps, Inc. ("Duff & Phelps") and "AAA" by Nippon
Investors Inc. Such ratings reflect only the views of the respective rating

subject to revision or withdrawal at any time by such rating agencies.

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

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

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

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

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

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

     As of December 31, 1993 and 1992, CapMAC had qualified statutory capital
(which consists of policyholders' surplus and contingency reserve) of
approximately $167 million and $161 million, respectively, and had not
incurred any debt obligations. Article 69 of the New York State Insurance Law
requires CapMAC to establish and maintain the contingency reserve, which is
available to cover claims under surety bonds issued by CapMAC.

     In addition to its qualified statutory capital and other reinsurance
available to pay claims under its surety bonds, CapMAC has entered into a Stop
Loss Reinsurance Agreement (the "Stop Loss Agreement") with Winterthur Swiss
Insurance Company (the "Reinsurer"), which is rated AAA by Standard & Poor's
and Aaa by Moody's, pursuant to which the Reinsurer will be required to pay
any losses incurred by CapMAC during the term of the Stop Loss Agreement on
the surety bonds covered under the Stop Loss Agreement in excess of a
specified amount of losses incurred by CapMAC under such surety bonds (such
specified amount initially being $100 million and increasing annually by an
amount equal to 66 2/3% of the increase in CapMAC's statutory capital and
surplus) up to an aggregate
 <PAGE>
                           Unitholder Explanations                          27
limit payable under the Stop Loss Agreement of $50 million. The Stop Loss
Agreement has a term of seven years, is extendable for one-year periods and is
subject to early termination upon the occurrence of certain events.

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

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

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

     Because the Bonds are insured by one of the Portfolio Insurers or one of
the Preinsured Bond Insurers as to the timely payment of principal and
interest, when due, and on the basis of the various reinsurance agreements in
effect, Standard & Poor's Corporation has assigned to the Units of each
Insured Trust its "AAA" investment rating. See "Description of Securities
Ratings". The obtaining of this rating by an Insured Trust should not be
construed as an approval of the offering of the Units by Standard & Poor's
Corporation or as a guarantee of the market value of such Trust or of the
Units.
   
     On the date of this Prospectus, the Estimated Current Return on the
Securities in the New Mexico IM-IT Trust was 5.55% after payment of the
insurance premium or premiums payable by such Trust, while the Estimated Long-
Term Return on such Trust was 5.57%. The Estimated Current Return on an
identical portfolio without the insurance obtained by the above-mentioned
Trust would have been 5.56% on such date, while the Estimated Long-Term Return
on an identical portfolio without the insurance obtained by the above
mentioned Trust would have been 5.59%.
    
     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
 <PAGE>
28                         Unitholder Explanations
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

IM-IT

      GENERAL. The IM-IT consists of 12 issues of Securities. None of the
Bonds in the IM-IT 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 located in 9
states or territories, divided by purpose of issues (and percentage of
principal amount to total IM-IT) as follows: Higher Education, 2 (22%);
Water and Sewer, 2 (21%); Health Care, 2 (17%); Retail Electric/Gas, 2 (14%);
Wholesale Electric, 1 (11%): Miscellaneous, 2 (10%); and Certificates of
Participation, 1 (5%). No Bond issue has received a provisional rating. The
dollar weighted average maturity of the Bonds in the Trust is 29 years.

     TAX STATUS. For a discussion of the Federal tax status of income earned

<FN>
<F1> During the first year the Trustee will reduce its fee by approximately
     $.10 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 $59.05.
     Estimated Annual Expense per Unit (excluding insurance) will be increased
     to $1.85; and estimated net annual interest income per Unit will remain
     the same as shown. See "Estimated Current Returns and Estimated Long-Term
     Returns." Based on the outstanding principal amount of Securities as of
     the Date of Deposit, the Trustee's annual fee would be $8,938.
<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. One of the Bonds in the IM-IT Intermediate Trust is a general
obligation of the governmental entity issuing it and is backed by the taxing
power thereof. The remaining issues are payable from the income of a specific
project or authority and are not supported by the issuer's power to levy
taxes. These issues are located in 8 states or territories, divided by purpose
of issues (and percentage of principal amount to total IM-IT Intermediate
Trust) as follows: Retail Electric/Gas, 4 (31%); Health Care, 3 (29%);
General Obligations, 1 (15%); Transportation, 1 (15%); Wholesale Electric, 1
(6%) and Higher Education, 1 (4%) . Three 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 Washington. 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 9.9 years.

<FN>
<F1> During the first year the Trustee will reduce its fee by approximately
     $.60 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
     $53.15. 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 $4,900.
<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".

NEW MEXICO IM-IT TRUST

      GENERAL. The New Mexico IM-IT Trust consists of 8 issues of Securities.
One of the Bonds in the New Mexico IM-IT Trust is a general obligation of the
governmental entity issuing it and is backed by the taxing power thereof. The
remaining issues are payable from the income of a specific project or
authority and are not supported by the issuer's power to levy taxes. These
issues are divided by purpose of issues (and percentage of principal amount to
total New Mexico IM-IT Trust) as follows: Retail Electric/Gas, 4 (50%); Health
Care, 1 (17%); Higher Education, 1 (13%); Transportation, 1 (13%) and General
Obligations, 1 (7%). No Bond issue has received a provisional rating.

     SPECIAL CONSIDERATIONS. New Mexico is the nation's fifth largest State in
terms of area. As of 1989 the federal government owns 34.1% of New Mexico's
land, State government, 11.8%, Indian tribes, 8.3%, leaving 45.8% in private
ownership. New Mexico has 33 counties and 99 incorporated places.

     Major industries in New Mexico are energy resources (crude petroleum,
natural gas, uranium, and coal), tourism, services, arts and crafts,
agriculture-agribusiness, government (including military), manufacturing, and
mining. Major scientific research facilities at Los Alamos, Albuquerque and
White Sands are also a notable part of the State's economy. New Mexico has a
thriving tourist industry.

     According to a June 1991 report of the Bureau of Business and Economic
Research of the University of New Mexico ("BBER"), New Mexico's recent
economic growth has been "subdued" and it appears that it will slow even
further before a turnaround occurs. Economic growth in New Mexico was strong
in 1989 and the first half of 1990, but declined substantially in the third
and fourth quarters of 1990. Among the localized events impacting New Mexico's
economy during 1990 were the curtailment of government funding for fusion
research at Los Alamos National Laboratory and for the Star Wars free-electron
laser at White Sands Missile Range and Los Alamos (loss of 600 jobs in the
aggregate); the move from Kirtland Air Force Base of a contract management
unit (200 jobs); the generally tight credit conditions, particularly for land
development and construction spending, which followed in the wake of
Resolution Trust Corporation takeovers of most of New Mexico's major savings
and loan associations; and oil prices which kept oil production in the State
on the decline.

     Agriculture is a major part of the state's economy. As a high relatively
dry region with extensive grasslands, New Mexico is ideal for raising cattle,
sheep, and other livestock. Because of irrigation and a variety of climatic
conditions, the state's farmers are able to produce a diverse assortment of
products. New Mexico's farmers are major producers of alfalfa hay, wheat,
chili peppers, cotton, fruits, and pecans. Agricultural businesses include
chili canneries, wineries, alfalfa pellets, chemicals and fertilizer plants,
farm machinery, feed lots, and commercial slaughter plants.

     New Mexico nonagricultural employment growth was only 2.3% in 1990.
During the first quarter of 1991, it was 1.3% compared to the first quarter of
1990 (net increase of 7,100 jobs), following a 1.2% increase in the fourth
quarter of 1990. These increases are about half the long-term trend growth
rate of 2.6% of the 1947-1990 period. Income growth remained relatively
strong, increasing 7.1% in the fourth quarter of 1990 (compared to a national
increase of 5.9%).

     The services sector continued to be the strongest in the State,
accounting for almost half of new jobs in the first quarter of 1991, a 2.7%
growth. Business services, health services and membership organizations
provided the bulk of services growth. The trade and government sectors had
much weaker growth in the first quarter of 1991, with 1.2% and 1.0% growth
rates, respectively.

     The mining sector added more than 350 jobs during 1990, most in oil and
gas. Oil well completions increased, even though oil production has been on a
slow decline. Gas well completions and gas production have also been growing,
as producers continue to take advantage of the coal seam gas tax credit, which
will continue to be available under current law through 1992.

     Construction employment declined for 21 consecutive quarters through the
first quarter of 1991, but was down only 0.4% in the first quarter of 1991,
after having averaged a 4.5% decline for each of the previous twenty quarters.
Housing construction remains depressed, with new housing unit authorizations
during 1990, both single family and multifamily, at their lowest levels in
more than fifteen years.

     The manufacturing sector showed a small increase (1.3%) during 1990,
while finance/insurance/real estate and
transportation/communications/utilities demonstrated small declines (1.0% and
0.9%, respectively).

     The foregoing information constitutes only a brief summary of information
about New Mexico. It does not describe the financial difficulties which may
impact certain issuers of Bonds and does not purport to be a complete or
exhaustive description of adverse conditions to which the issuers in the New
Mexico IM-IT Trust are subject. Additionally, many factors including national
economic, social and environmental policies and conditions, which are not
within the control of the issuers of Bonds, could have an adverse impact on
the financial condition of the State and various agencies and political
subdivisions located in the State. The Sponsor is unable to predict whether or
to what extent such factors or other factors may affect the issuers of Bonds,
the market value or marketability of the Bonds or the ability of the
respective issuers of the Bonds acquired by the New Mexico IM-IT Trust to pay
interest on or principal of the bonds.

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

     The assets of the New Mexico IM-IT Trust will consist of interest-bearing
obligations issued by or on behalf of the State of New Mexico ("New Mexico")
or counties, municipalities, authorities or political subdivisions thereof
(the "New Mexico Bonds"), and by or on behalf of the government of Puerto
Rico, the government of the Guam, or the government of the Virgin Islands
(collectively the "Possession Bonds") (collectively the New Mexico Bonds and
the Possession Bonds shall be referred to herein as the "Bonds") the interest
on which is expected to qualify as exempt from New Mexico income taxes.

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

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

     (1) The New Mexico IM-IT Trust will not be subject to tax under the New
Mexico State Income Tax.

     (2) Income on the Bonds which is exempt from the New Mexico State Income
Tax when received by the New Mexico IM-IT Trust, and which would be exempt
from the New Mexico State Income Tax if received directly by a Unitholder,
will retain its status as exempt from such tax when received by the New Mexico
IM-IT Trust and distributed to such Unitholder provided that the New Mexico
Trust complies with the reporting requirements contained in the New Mexico
State Income Tax regulations.

     (3) To the extent that interest income derived from the New Mexico IM-IT
Trust by a Unitholder with respect to Possession Bonds is excludable from
gross income for federal income tax purposes pursuant to 48 U.S.C. Section
745, 48 U.S.C. Section 1423a or 48 U.S.C. Section 1403, such interest income
will not be subject to New Mexico State Income Tax.

     (4) Each Unitholder will recognize gain or loss for New Mexico Income Tax
purposes if the Trustee disposes of a bond (whether by redemption, sale or
otherwise) or if the Unitholder redeems or sells Units of the New Mexico IM-IT
Trust to the extent that such a transaction results in a recognized gain or
loss to such Unitholder for federal income tax purposes.

                         New Mexico IM-IT-- Series 14                       35

     (5) The New Mexico State Income Tax does not permit a deduction of
interest paid on indebtedness or other expenses incurred (or continued) in
connection with the purchase or carrying of Units in the New Mexico IM-IT
Trust to the extent that interest income related to the ownership of Units is
exempt from the New Mexico State Income Tax.

     Investors should consult their tax advisors regarding collateral tax
consequences under New Mexico law relating to the ownership of the Units,
including, but not limited to, the inclusion of income attributable to
ownership of the Units in "modified gross income" for purposes of determining
eligibility for and the amount of the low income comprehensive tax rebate, the
child day care credit, and the elderly taxpayers' property tax rebate and the
applicability of other New Mexico taxes, such as the New Mexico estate tax.

<F1> Excluding insurance costs.
<F2> The Estimated Current Return and Estimated Long-Term Return are increased
     for transactions entitled to a reduced sales charge. See "Unitholder
     Explanations--Public Offering--General".
<F3> The Estimated Current Return is calculated by dividing the estimated net
     annual interest income per Unit by the Public Offering Price. The
     estimated net annual interest income per Unit will vary with changes in
     fees and expenses of the Trustee and the Evaluator and with the principal
     prepayment, redemption, maturity, exchange or sale of Securities while
     the Public Offering Price will vary with changes in the offering price of
     the underlying Securities and with changes in the Purchased Interest;
     therefore, there is no assurance that the present Estimated Current
     Return indicated above will be realized in the future. The Estimated
     Long-Term Return is calculated using a formula which <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".

PENNSYLVANIA IM-IT TRUST

      GENERAL. The Pennsylvania IM-IT Trust consists of 9 issues of
Securities. Two of the Bonds in the Pennsylvania 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 Pennsylvania IM-IT Trust) as follows: Health Care, 2
(30%); Water and Sewer, 2 (23%); General Obligations, 2 (20%); Higher
Education, 1 (16%); General Purpose 1, (8%) and Retail Electric/Gas, 1 (3%).
No Bond issue has received a provisional rating.

     SPECIAL CONSIDERATIONS. Investors should be aware of certain factors that
might affect the financial conditions of the Commonwealth of Pennsylvania.
Pennsylvania historically has been identified as a heavy industry state
although that reputation has changed recently as the industrial composition of
the Commonwealth diversified when the coal, steel and railroad industries
began to decline. The major new sources of growth in Pennsylvania are in the
service sector, including trade, medical and the health services, education
and financial institutions. Pennsylvania's agricultural industries are also an
important component of the Commonwealth's economic structure, accounting for
more than $3.5 billion in crop and livestock products annually, while
agribusiness and food related industries support $38 billion in economic
activity annually.

     Non-agricultural employment in the Commonwealth declined by 5.1 percent
during the recessionary period from 1980 to 1983. In 1984, the declining trend
was reversed as employment grew by 2.9 percent over 1983 levels. From 1983 to
1990, Commonwealth employment continued to grow each year, increasing an
additional 14.3 percent. For the last two years, unemployment in the
Commonwealth has declined 1.9 percent. The growth in employment experienced in
Pennsylvania is comparable to the growth in employment in the Middle Atlantic
Region which has occurred during this period.

     Back to back recessions in the early 1980's reduced the manufacturing
sector's employment levels moderately during 1980 and 1981, sharply during
1982, and even further in 1983. Non-manufacturing employment has increased
steadily since 1980 to its 1992 level of 81.3 percent of total Commonwealth
employment. Consequently, manufacturing employment constitutes a diminished
share of total employment within the Commonwealth. Manufacturing, contributing
18.7 percent of 1992 non-agricultural employment, has fallen behind both the
services sector and the trade sector as the largest single source of
employment within the Commonwealth. In 1992 the services sector accounted for
29.3 percent of all non-agricultural employment while the trade sector
accounted for 22.7 percent.

     From 1983 to 1989, Pennsylvania's annual average unemployment rate
dropped from 11.8 percent to 4.5 percent, falling below the national rate in
1986 for the first time in over a decade. Pennsylvania's annual average
unemployment rate remained below the national average from 1986 until 1990.
Slower economic growth caused the unemployment rate in the Commonwealth to
rise to 6.9 percent in 1991 and 7.5 percent in 1992. As of February 1994, the
seasonally adjusted unemployment rate for the Commonwealth was 5.1 percent
compared to 6.5 percent for the United States.

     The five year period from fiscal 1989 through fiscal 1993 was marked by
public health and welfare costs growing at a rate double the growth for all
the state expenditures. Rising caseloads, increased utilization of services
and rising prices joined to produce the rapid rise of public health and
welfare costs at a time when a national recession caused tax revenues to
stagnate and even decline. During the period from fiscal 1989 through fiscal
1993, public health and welfare costs rose by an average annual rate of 10.9
percent while tax revenues were growing at an average annual rate of 5.5
percent. Consequently, spending on other budget programs was restrained to a
growth rate below 5.0 percent and sources of revenues other than taxes became
larger components of fund revenues. Among those sources are transfers from
other funds and hospital and nursing home pooling of contributions to use as
federal matching funds.

     Tax revenues declined in fiscal 1991 as a result of the recession in the
economy. A $2.7 billion tax increase enacted for fiscal 1992 brought financial
stability to the General Fund. That tax increase included several taxes with
 <PAGE>
38                     Pennsylvania IM-IT-- Series 187
retroactive effective dates which generated some one-time revenues during
fiscal 1992. The absence of those revenues in fiscal 1993 contributed to the
decline in tax revenues shown for fiscal 1993.

     It should be noted that the creditworthiness of obligations issued by
local Pennsylvania issuers may be unrelated to the creditworthiness of
obligations issued by the Commonwealth of Pennsylvania, and there is no
obligation on the part of the Commonwealth to make payment on such local
obligations in the event of default.

     Financial information for the General Fund is maintained on a budgetary
basis of accounting. A budgetary basis of accounting is used for the purpose
of ensuring compliance with the enacted operating budget and is governed by
applicable statutes of the Commonwealth and by administrative procedures. The
Commonwealth also prepares annual financial statements in accordance with
generally accepted accounting principles ("GAAP"). The budgetary basis
financial information maintained by the Commonwealth to monitor and enforce
budgetary control is adjusted at fiscal year-end to reflect appropriate
accruals for financial reporting in conformity with GAAP.

     Fiscal 1991 Financial Results. GAAP Basis: During fiscal 1991 the General
Fund experienced an $861.2 million operating deficit resulting in a fund
balance deficit of $980.9 million at June 30, 1991. The operating deficit was
a consequence of the effect of a national recession that restrained budget
revenues and pushed expenditures above budgeted levels. At June 30, 1991, a
negative unreserved-undesignated balance of $1,146.2 million was reported.
During fiscal 1991 the balance in the Tax Stabilization Reserve Fund was used
to maintain vital state spending.

     Budgetary Basis: A deficit of $453.6 million was recorded by the General
Fund at June 30, 1991. The deficit was a consequence of higher than budgeted
expenditures and lower than estimated revenues during the fiscal year brought
about by the national economic recession that began during the fiscal year.
The budgetary basis deficit at June 30, 1991 was carried into the 1992 fiscal
year and funded in the fiscal 1992 budget. A number of actions were taken
throughout the fiscal year by the Commonwealth to mitigate the effects of the
recession on budget revenues and expenditures. Actions taken, together with
normal appropriation lapses, produced $871 million in expenditure reductions
and revenue increases for the fiscal year. The most significant of these
actions were a $214 million transfer from the Pennsylvania Industrial
Development Authority, a $134 million transfer from the Tax Stabilization
Reserve Fund, and a pooled financing program to match federal Medicaid funds
replacing $145 million of state funds.

     Fiscal 1992 Financial Results. GAAP Basis: During fiscal 1992 the General
Fund reported a $1.1 billion operating surplus. This operating surplus was
achieved through legislated tax rate increases and tax base broadening
measures enacted in August 1991 and by controlling expenditures through
numerous cost reduction measures implemented throughout the fiscal year. As a
result of the fiscal 1992 operating surplus, the fund balance has increased to
$87.5 million and the unreserved-undesignated deficit has dropped to $138.6
million from its fiscal 1991 level of $1,146.2 million.

     Budgetary Basis: Eliminating the budget deficit carried into fiscal 1992
from fiscal 1991 and providing revenues for fiscal 1992 budgeted expenditures
required tax revisions that are estimated to have increased receipts for the
1992 fiscal year by over $2.7 billion. Total revenues for the fiscal year were
$14,516.8 million, a $2,654.5 million increase over cash revenues during
fiscal 1991. Originally based on forecasts for an economic recovery, the
budget revenue estimates were revised downward during the fiscal year to
reflect continued recessionary economic activity. Largely due to the tax
revisions enacted for the budget, corporate tax receipts totalled $3,761.2
million, up from $2,656.3 million in fiscal 1991, sales tax receipts increased
by $302 million to $4,499.7 million, and personal income tax receipts totalled
$4,807.4 million, an increase of $1,443.8 million over receipts in fiscal
1991.

     As a result of the lowered revenue estimate during the fiscal year,
increased emphasis was placed on restraining expenditure growth and reducing
expenditure levels. A number of cost reductions were implemented during the
fiscal year and contributed to $296.8 million of appropriation lapses. These
appropriation lapses were responsible for the $8.8 million surplus at fiscal
year-end, after accounting for the required ten percent transfer of the
surplus to the Tax Stabilization Reserve Fund.

     Spending increases in the fiscal 1992 budget were largely accounted for
by increases for education, social services and corrections programs.
Commonwealth funds for the support of public schools were increased by 9.8
percent to provide a $438 million increase to $4.9 billion for fiscal 1992.
The fiscal 1992 budget provided additional
 <PAGE>
                       Pennsylvania IM-IT-- Series 187                      39
funds for basic and special education and included provisions designed to help
restrain the annual increase of special education costs, an area of recent
rapid cost increases. Child welfare appropriations supporting county operated
child welfare programs were increased $67 million, more than 31.5 percent over
fiscal 1991. Other social service areas such as medical and cash assistance
also received significant funding increases as costs have risen quickly as a
result of the economic recession and high inflation rates of medical care
costs. The costs of corrections programs, reflecting the marked increase in
the prisoner population, increased by 12 percent. Economic development
efforts, largely funded from bond proceeds in fiscal 1991, were continued with
General Fund appropriations for fiscal 1992.

     The budget included the use of several Medicaid pooled financing
transactions. These pooling transactions replaced $135 million of Commonwealth
funds, allowing total spending under the budget to increase by an equal
amount.

     Fiscal 1993 Financial Results--GAAP Basis. The fund balance of the
General Fund increased by $611.4 million during the fiscal year, led by an
increase in the unreserved balance of $576.8 million over the prior fiscal
year balance. At June 30, 1993, the fund balance totaled $698.9 and the
unreserved/undesignated balance totaled $64.4 million. A continuing recovery
of the Commonwealth's financial condition from the effects of the national
economic recession of 1990 and 1991 is demonstrated by this increase in the
balance and a return to a positive unreserved/ undesignated balance. The
previous positive unreserved/undesignated balance was recorded in fiscal 1987.
For the second consecutive fiscal year the increase in the
unreserved/undesignated balance exceeded the increase recorded in the
budgetary basis unappropriated surplus during the fiscal year.

     Budgetary Basis. The 1993 fiscal year closed with revenues higher than
anticipated and expenditures about as projected, resulting in an ending
unappropriated balance surplus (prior to the ten percent transfer to the Tax
Stabilization Reserve Fund) of $242.3 million, slightly higher than estimated
in May 1993. Cash revenues were $41.5 million above the budget estimate and
totaled $14.633 billion representing less than a one percent increase over
revenues for the 1992 fiscal year. A reduction in the personal income tax rate
in July 1992 and revenues from retroactive corporate tax increases received in
fiscal 1992 were responsible, in part, for the low revenue growth in fiscal
1993.

     Appropriations less lapses totaled an estimated $13.870 billion
representing a 1.1 percent increase over those during fiscal 1992. The low
growth in spending is a consequence of a low rate of revenue growth,
significant one-time expenses during fiscal 1992, increased tax refund
reserves to cushion against adverse decisions on pending litigations, and the
receipt of federal funds for expenditures previously paid out of Commonwealth
funds.

     By state statute, ten percent of the budgetary basis unappropriated
surplus at the end of a fiscal year is to be transferred to the Tax
Stabilization Reserve Fund. The transfer for the fiscal 1993 balance is $24.2
million. The remaining unappropriated surplus of $218.0 million was carried
forward into the 1994 fiscal year.

     Fiscal 1994 Budget (Budgetary Basis). The enacted 1994 fiscal year budget
provides for $14.995 billion of appropriations of Commonwealth funds. The
largest increase in appropriations is for the Department of Public
Welfare--$235 million--to meet the increasing costs of medical care and rising
caseloads. Other large increases are education--$196 million--including $129
million to increase state educational subsidies for the most needy school
districts and $104 million for correctional institutions to pay operating
costs and lease payments for five new prisons and to expand the capacity of
two existing facilities.

     The continuing rise in medical assistance costs cannot be met from the
resources provided by a much slower growing tax revenue base. Consequently,
program and financial changes must be implemented to keep costs within budget
limits. For fiscal 1994, the Commonwealth plans to save $247 million by
receiving federal reimbursement for hospital services provided to state
general assistance recipients. Prior to this time, those costs were fully paid
by the Commonwealth. In addition, the Commonwealth will continue to use pooled
financing for medical assistance costs using intergovernmental transfers in
place of voluntary contributions as was done in earlier fiscal years. Through
the pooled financing, additional federal reimbursements may be drawn to
support the medical assistance program. The pooled financing is anticipated to
replace $99 million of Commonwealth funds in the 1994 fiscal year budget.

     The budget estimates revenue growth of 3.7 percent over fiscal 1993
actual revenues. The revenue estimate is based on an expectation of continued
economic recovery, but at a slow rate. Sales tax receipts are projected to
rise 4.4 percent over 1993 receipts while personal income tax receipts are
projected to increase by 3.3 percent, a rate that is low because of the tax
rate reduction in July 1992.

     In February 1994, the Governor recommended $46.4 million of additional
appropriations be enacted for fiscal 1994, raising total appropriations to
$15,041.7 million. The largest increase in additional appropriations is $27.3
million to make audit payments to the federal Department of Health and Human
Services. No change to the aggregate commonwealth revenue estimate was made
although individual tax estimates have been revised to reflect actual receipts
to date and the tax refund estimate was reduced to reflect a favorable ruling
in Philadelphia Suburban Corp. vs. Commonwealth. Through February 1994,
revenues are slightly ($1.1 million or 0.01 percent) above estimate as below
estimate corporate tax receipts are being offset by above estimate sales tax,
personal income tax and non-tax revenue receipts.

     Upon completion of a review of actual expenditures and revised estimates
for the remainder of fiscal 1994, lapses of current and prior years'
appropriations are projected to be $163.0 million. The projected lapses and
the beginning unappropriated surplus contribute to a projected ending
unappropriated surplus of $296.8 million before the required ten percent
transfer to the Tax Stabilization Reserve Fund.

     Proposed Fiscal 1995 Budget. For the fiscal year beginning July 1, 1994,
the Governor has proposed a budget containing a 4.1 percent increase in
appropriations over the actual and proposed supplemental appropriations for
fiscal 1994. Total appropriations recommended amount to $15,665 million. The
budget is balanced by drawing down of a projected $267 million unappropriated
surplus for fiscal 1994. The fastest growing portion of the budget continues
to be medical assistance which is proposed to receive the largest increase,
$264 million or 42.4 percent of the proposed net increase in spending. Other
program areas budgeted to receive major increases are education-- $165
million--and corrections--$126 million. The proposed budget recommends a
tightening of eligibility criteria for state-financed welfare benefits as a
cost reduction measure. Those individuals not meeting the revised criteria
would only qualify for 60 days of cash grants in a two-year period.

     The Governor's proposal also includes a recommended reduction in the
corporate net income tax rate from 12.25 percent to 9.99 percent over a three
year period. The corporate tax cut and a proposed increase in poverty
exemption for the person income tax are estimated to cost $124.7 million in
fiscal 1995.

     The recommended budget includes Commonwealth revenue growth of 4.7
percent without the effect of the proposed tax reduction. The revenue estimate
is based on the expectation of a continued slow national economic recovery and
continued economic growth of the Pennsylvania economy at a rate slightly below
the national rate. Total estimate Commonwealth revenue, adjusted for refunds
and the proposed tax reduction, is $15,400 million.

     All outstanding general obligation bonds of the Commonwealth are rated
AA-by S&P and A1 by Moody's.

     Any explanation concerning the significance of such ratings must be
obtained from the rating agencies. There is no assurance that any ratings will
continue for any period of time or that they will not be revised or withdrawn.

     The City of Philadelphia ("Philadelphia") is the largest city in the
Commonwealth, with an estimated population of 1,585,577 according to the 1990
Census. Philadelphia functions both as a city of the first class and a county
for the purpose of administering various governmental programs.

     For the fiscal year ending June 30, 1991, Philadelphia experienced a
cumulative General Fund balance deficit of $153.5 million. The audit findings
for the fiscal year ending June 30, 1992, place the Cumulative General Fund
balance deficit at $224.9.

     Legislation providing for the establishment of the Pennsylvania
Intergovernmental Cooperation Authority ("PICA") to assist first class cities
in remedying fiscal emergencies was enacted by the General Assembly and
approved by the Governor in June, 1991. PICA is designed to provide assistance
through the issuance of funding debt to liquidate budget deficits and to make
factual findings and recommendations to the assisted city concerning its
budgetary and fiscal affairs. An intergovernmental cooperation agreement
between Philadelphia and PICA was approved by City Council on January 3, 1992,
and approved by the PICA Board and signed by the Mayor on January
 <PAGE>
                       Pennsylvania IM-IT-- Series 187                      41
8, 1992. At this time, Philadelphia is operating under a five year fiscal plan
approved by PICA on April 6, 1992. Full implementation of the five year plan
was delayed due to labor negotiations that were not completed until October
1992, three months after the expiration of the old labor contracts. The terms
of the new labor contracts are estimated to cost approximately $144.0 million
more than what was budgeted in the original five year plan. An amended five
year plan was apporoved by PICA in May 1993. The audit findings show a surplus
of approximately $3 million for the fiscal year ending June 30, 1993. The
fiscal 1994 budget projects no deficit and a balanced budget for the year
ending June 30, 1994. The Mayor presented the latest update of the five year
financial plan on January 13, 1994; it will be considered by PICA in the
spring of 1994.

     In June 1992, PICA issued $474,555,000 of its Special Tax Revenue Bonds
to provide financial assistance to Philadelphia and to liquidate the
cumulative General Fund balance deficit. In July 1993, PICA issued
$643,430,000 of Special Tax Revenue Bonds to refund certain general obligation
bonds of the city and to fund additional capital projects.

     As of the date hereof, the ratings on the City's long-term obligations
supported by payments from the City's General Fund are rated Ba by Moody's and
BB by S&P. Any explanation concerning the significance of such ratings must be
obtained from the rating agencies. There is no assurance that any ratings will
continue for any period of time or that they will not be revised or withdrawn.

     The foregoing information constitutes only a brief summary of some of the
financial difficulties which may impact certain issuers of bonds and does not
purport to be a complete or exhaustive description of all adverse conditions
to which the issuers of the Bonds in the Pennsylvania IM-IT Trust are subject.
Additionally, many factors including national economic, social and
environmental policies and conditions, which are not within the control of the
issuers of Bonds, could have an adverse impact on the financial condition of
the State and various agencies and political subdivisions located in the
State. The Sponsor is unable to predict whether or to what extent such factors
or other factors may affect the issuers of Bonds, the market value or
marketability of the Bonds or the ability of the respective issuers of the
Bonds acquired by the Pennsylvania IM-IT Trust to pay Interest on or principal
of the Bonds.

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

     In the opinion of Saul, Ewing, Remick & Saul, counsel to the Fund for
Pennsylvania tax matters, under existing law:

     (1)   Units evidencing fractional undivided interest in the Pennsylvania
        IM-IT Trust, which are represented by obligations issued by the
        Commonwealth of Pennsylvania, any public authority, commission, board
        or other agency created by the Commonwealth of Pennsylvania, any
        political subdivision of the Commonwealth of Pennsylvania or any
        public authority created by any such political subdivision are not
        taxable under any of the personal property taxes presently in effect
        in Pennsylvania;
     (2)   distributions of interest income to Unitholders are not subject to
        personal income tax under the Pennsylvania Tax Reform Code of 1971;
        nor will such interest be taxable under the Philadelphia School
        District Investment Income Tax imposed on Philadelphia resident
        individuals;
     (3)   a Unitholder may have a taxable event under the Pennsylvania state
        and local income taxes referred to in the preceding paragraph upon the
        redemption or sale of his Units but not upon the disposition of any of
        the Securities in the Pennsylvania IM-IT Trust to which the
        Unitholder's Units relate;
     (4)   Units are subject to Pennsylvania inheritance and estate taxes;
     (5)   a Unitholder which is a corporation may have a taxable event under
        the Pennsylvania Corporate Net Income Tax when it redeems or sells its
        Units. Interest income distributed to Unitholders which are
        corporations is not subject to Pennsylvania Corporate Net Income Tax
        or Mutual Thrift Institutions Tax. However, banks, title insurance
        companies and trust companies may be required to take the value of the
        Units into account in determining the taxable value of their Shares
        subject to Shares Tax;
     (6)   Under Act No. 68 of December 3, 1993, gains derived by the Fund
        from the sale, exchange or other disposition of Bonds may be subject
        to Pennsylvania personal or corporate income taxes. Those gains which
        are distributed by the Fund to Unitholders who are individual will be
        subject to Pennsylvania
 <PAGE>
42                     Pennsylvania IM-IT-- Series 187
        Personal Income Tax and, for residents of Philadelphia, to
        Philadelphia School District Investment Income Tax. For Unitholders
        which are corporations, the distributed gains will be subject to
        Corporate Net Income Tax or Mutual Thrift Institutions Tax. Gains
        which are not distributed by the Fund will nevertheless be taxable to
        Unitholders if derived by the Fund from the sale, exchange or other
        disposition of Bonds issued on or after February 1, 1994. Gains which
        are not distributed by the Fund will remain nontaxable to Unitholders
        if derived by the Fund from the sale, exchange or other disposition of
        Bonds issued prior to February 1, 1994. However, for gains from the
        sale, exchange or other disposition of these Bonds to be taxable under
        the Philadelphia School District Investment Income Tax, the Bonds must
        be held for six months or less;
     (7)   any proceeds paid under the insurance policy issued to the Trustee
        or obtained by the issuers of the Bonds with respect to the Bonds
        which represent maturing interest on defaulted obligations held by the
        Trustee will be excludable from Pennsylvania 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
     (8)   The Fund is not taxable as a corporation under Pennsylvania tax
        laws applicable to corporations.

     On December 3, 1993, change to Pennsylvania law affecting taxation of
income and gains from the sale of Commonwealth of Pennsylvania and local
obligations were enacted. Among these changes was the repeal of the exemption
from tax of gains realized upon the sale or other disposition of such
obligations. The Pennsylvania Department of Revenue has not issued any
regulations or other guidance concerning these changes. The opinions expressed
above are based on our analysis of the law but are subject to modification
upon review of regulations or other guidance that may be issued by the
Department of Revenue.

     In rendering its opinion, Saul, Ewing, Remick & Saul has not, for timing
reasons, made an independent review of proceedings related to the issuance of
the Bonds. It has relied on Van Kampen Merritt Inc. for assurance that the
Bonds have been issued by the Commonwealth of Pennsylvania or by or on behalf
of municipalities or other governmental agencies within the Commonwealth.

<F1> During the first year the Trustee will reduce its fee by approximately
     $.63 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 $58.37.
     Estimated Annual Expense per Unit (excluding insurance) will be increased
     to $2.03; 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 $3,009.
<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".

                         Kentucky QUALITY-- Series 51                       45
   
KENTUCKY QUALITY TRUST

      GENERAL. The Kentucky Quality Trust consists of 9 issues of Securities.
None of the Bonds in the Kentucky Quality 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 Kentucky Quality Trust) as follows: Retail Electric/Gas, 2 (31%);
General Purpose, 1 (16%); Public Building, 1 (16%); Health Care, 1 (15%);
Water and Sewer, 2 (11%); Higher Education, 1 (6%) and Multi-Family Mortgage
Revenue, 1 (5%). No Bond issue has received a provisional rating.

     SPECIAL CONSIDERATIONS. The Commonwealth of Kentucky leads the nation in
total tonnage of coal produced and ranks among the top 10 states in the value
of all minerals produced. Tobacco is the dominant agricultural crop and
Kentucky ranks second among the states in the total cash value of tobacco
raised. The manufacturing mix in the state reflects a significant
diversification. In addition to the traditional concentration of tobacco
processing plants and bourbon distilleries, there is considerable durable
goods production, such as automobiles, heavy machinery, consumer appliances,
and office equipment. The State's parks system and the horse breeding and
racing industry, symbolized by the Kentucky Derby, play an important role in
an expanding tourist business in the state.

     Current economic problems, including particularly the continuing high
unemployment rate, have had varying effects on the differing geographic areas
of the State and the political subdivisions located within such geographic
areas. Although revenue obligations of the State or its political subdivisions
may be payable from a specific source or project, there can be no assurance
that further economic difficulties and the resulting impact on State and local
governmental finances will not adversely affect the market value of the Bonds
in the Kentucky Quality Trust or the ability of the respective obligors to pay
debt service of such Bonds.

     Prospective investors should study with care the portfolio of Bonds in
the Kentucky Quality Trust and should consult with their investment advisors
as to the merits of particular issues in the portfolio.

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

     In the opinion of Harper, Ferguson & Davis, special counsel to the Fund
for Kentucky tax matters, under existing Kentucky law:

     Because Kentucky income tax law is based upon the Federal law and in
explicit reliance upon the opinion of Chapman and Cutler referred to above,
and in further reliance on the determination letter to us of the Revenue
Cabinet of Kentucky dated May 10, 1984, it is our opinion that the application
of existing Kentucky income tax law would be as follows:

     (1)   Each Kentucky Unitholder will be treated as the owner of a pro rata
        portion of the Kentucky Quality Trust for Kentucky income tax
        purposes, and the income of the Kentucky Quality Trust will therefore
        be treated as the income of the Kentucky Unitholders under Kentucky
        law;

     (2)   Interest on Bonds that would be exempt from Federal income taxation
        when paid directly to a Kentucky Unitholder will be exempt from
        Kentucky income taxation when: (i) received by the Kentucky Quality
        Trust and attributed to such Kentucky Unitholder; and (ii) when
        distributed to such Kentucky Unitholder;

     (3)   Each Kentucky Unitholder will realize taxable gain or loss when the
        Kentucky Quality Trust disposes of a Bond (whether by sale, exchange,
        redemption or payment at maturity) or when the Kentucky Unitholder
        redeems or sells Units at a price that differs from original cost as
        adjusted for amortization or accrual, as appropriate, of bond discount
        or premium and other basis adjustments (including any basis reduction
        that may be required to reflect a Kentucky Unitholder's share of
        interest, if any, accruing on Bonds during the interval between the
        Kentucky Unitholder's settlement date and the date such Bonds are
        delivered to the Kentucky Quality Trust, if later);
     (4)   Tax cost reduction requirements relating to amortization of bond
        premium may, under some
        circumstances, result in Kentucky Unitholders realizing taxable gain
        when their Units are sold or redeemed for an amount equal to or less
        than their original cost;
 <PAGE>
46                       Kentucky QUALITY-- Series 51

     (5)   Units of the Kentucky Quality Trust, to the extent the same
        represent an ownership in obligations issued by or on behalf of the
        Commonwealth of Kentucky or governmental units of the Commonwealth of
        Kentucky, the interest on which is exempt from Federal and Kentucky
        income taxation will not be subject to ad valorem taxation by the
        Commonwealth of Kentucky or any political subdivision thereof; and
     (6)   If interest or indebtedness incurred or continued by a Kentucky
        Unitholder to purchase Units in the Kentucky Quality Trust is not
        deductible for Federal income tax purposes, it also will be
        nondeductible for Kentucky income tax purposes.

<F1> During the first year the Trustee will reduce its fee by approximately
     $.05 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 b that amount indicated
     above. Estimated annual interest income per Unit will be increased to
     $58.80. Estimated Annual Expense per Unit (excluding insurance) will be
     increased to $1.98; 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 $3,116.
<F2> The Estimated Current Return and Estimated Long-Term Return are increased
     for transactions entitled to a reduced sales charge. See "Unitholder
     Explanations--Public Offering--General".
<F3> The Estimated Current Return is calculated by dividing the estimated net
     annual interest income per Unit by the Public Offering Price. The
     estimated net annual interest income per Unit will vary with changes in
     fees and expenses of the Trustee and the Evaluator and with the principal
     prepayment, redemption, maturity, exchange or sale of Securities while
     the Public Offering Price will vary with changes in the offering price of
     the underlying Securities and with changes in the Purchased Interest;
     therefore, there is no assurance that the present Estimated Current
     Return indicated above will be realized in the future. The Estimated
     Long-Term Return is calculated using a formula which <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".

NORTH CAROLINA QUALITY TRUST

      GENERAL. The North Carolina Quality Trust consists of 8 issues of
Securities. None of the Bonds in the North Carolina Quality 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 North Carolina Quality Trust) as follows: Health
Care, 3 (33%); Wholesale Electric, 2 (31%); Multi-Family Mortgage Revenue, 1
(20%); Certificates of Participation, 1 (9%) and Higher Education, 1 (7%). No
Bond issue has received a provisional rating.

     SPECIAL CONSIDERATIONS. See Portfolio for a list of the Debt Obligations
included in the North Carolina Quality Trust. The portions of the following
discussion regarding the financial condition of the State government may not
be relevant to general obligation or revenue bonds issued by political
subdivisions of the State. Those portions and the sections which follow
regarding the economy of the State, are included for the purpose of providing
information about general economic conditions that may or may not affect
issuers of the North Carolina obligations.

     General obligations of a city, town or county in North Carolina are
payable from the general revenues of the entity, including ad valorem tax
revenues on property within the jurisdiction. Revenue bonds issued by North
Carolina political subdivisions include (1) revenue bonds payable exclusively
from revenue-producing governmental enterprises and (2) industrial revenue
bonds, college and hospital revenue bonds and other "private activity bonds"
which are essentially non-governmental debt issues and which are payable
exclusively by private entities such as non-profit organizations and business
concerns of all sizes. State and local governments have no obligation to
provide for payment of such private activity bonds and in many cases would be
legally prohibited from doing so. The value of such private activity bonds may
be affected by a wide variety of factors relevant to particular localities or
industries, including economic developments outside of North Carolina.

     Section 23-48 of the North Carolina General Statutes appears to permit
any city, town, school district, county or other taxing district to avail
itself of the provisions of Chapter 9 of the United States Bankruptcy Code,
but only with the consent of the Local Government Commission of the State and
of the holders of such percentage or percentages of the indebtedness of the
issuer as may be required by the Bankruptcy Code (if any such consent is
required). Thus, although limitations apply, in certain circumstances
political subdivisions might be able to seek the protection of the Bankruptcy
Code.

     State Budget and Revenues. The North Carolina State Constitution requires
that the total expenditures of the State for the fiscal period covered by each
budget not exceed the total of receipts during the fiscal period and the
surplus remaining in the State Treasury at the beginning of the period. The
State's fiscal year runs from July 1st through June 30th.

     In 1990 and 1991, the State had difficulty meeting its budget
projections. The General Assembly responded by enacting a number of new taxes
and fees, which generated an estimated $665.5 million in fiscal year 1991-92.
Revenues for 1992-93 were estimated to include an additional $95.6 million and
helped produce a budget surplus (approximately $342 million) for the 1992-1993
fiscal year.

     In addition, the 1993 Session of the General Assembly reduced allowable
departmental operating expenditures by $120.3 and $122.8 million for fiscal
years 1993-94 and 1994-95 respectively, and authorized continuation funding of
approximately $8.33 billion for fiscal year 1993-94 and $8.60 billion for
fiscal year 1994-95. The savings reductions were based on recommendations from
the Governor, the Government Performance Audit Committee and selected savings
identified by the General Assembly.

     Both the nation and the State have experienced a modest economic recovery
in recent months. However, it is unclear what effect these developments, as
well as the reduction in government spending or increase in taxes may have on
the value of the Debt Obligations in the North Carolina Trust. No solid upward
economic trend has developed, and both the State and the national economies
must be watched carefully.

     The fiscal condition of the State might be affected adversely by
litigation concerning the legality of certain State tax provisions following
the March 1989 decision of the United States Supreme Court that it is
unconstitutional for a
 <PAGE>
                      North Carolina QUALITY-- Series 75                    49
state to exempt from state income taxation retirement benefits paid by the
state or its local governments, but not to exempt retirement benefits paid by
the federal government.

     Based on that decision, certain federal retirees and federal military
personnel plaintiffs brought an action in federal court against the North
Carolina Department of Revenue and certain officials of the State alleging the
unconstitutionality of taxes collected under prior North Carolina tax statutes
and seeking damages for the illegally collected taxes paid on federal
retirement or military pay for the years 1985-88 (covering the asserted 3 year
limitations period), plus interest. Swanson, et al. v. Powers, et al. (United
States District Court for the Eastern District of North Carolina, No.
89-282-CIV-5-H) ("Swanson Federal"). The individual plaintiffs in Swanson
Federal also brought an action in North Carolina state court seeking refunds
of the illegal taxes. Swanson, et al. v. State of North Carolina, et al. (Wake
County, North Carolina Superior Court, No. 90 CVS 3127) ("Swanson State").

     The amounts claimed by federal retirees in the Swanson actions have not
been precisely calculated. Plaintiffs have asserted that the plaintiff class
contains about 100,000 taxpayers; the State has asserted that the claims would
aggregate at least $140 million (which might not include interest).

     In Swanson State, the North Carolina Supreme Court found for the State,
ruling that the State would not be required to refund taxes illegally
collected prior to the U.S. Supreme Court's decision. The U.S. Supreme Court
vacated the judgment and remanded the case to the North Carolina Supreme Court
for reconsideration in light of the U.S. Supreme Court's holding in Harper v.
Virginia Dept. of Taxation (No. 91-794) ("Harper"). In Harper, which also
involved the disparate income tax treatment of retired state and federal
employees and the question of retroactive application of the law, the U.S.
Supreme Court held that the Commonwealth of Virginia must provide "meaningful
backward-looking relief" to the plaintiffs, if the Commonwealth did not have a
predeprivation process adequate to satisfy due process requirements. The case
was remanded to the Supreme Court of Virginia to determine whether a remedy
was required and, if so, what form it would take.

     The impact of Harper on the estimated $140 million of refund claims in
Swanson State has yet to be determined. On March 4, 1994 (in an unpublished
opinion), the North Carolina Supreme Court decided in favor of the State,
dismissing the Swanson State case. The plaintiffs reportedly will appeal to
the United States Supreme Court.

     The decision in Harper also reactivated the damage claims in Swanson
Federal, and the federal court will begin hearing arguments on these claims in
February 1994.

     General. The population of the State has increased 13% from 1980, from
5,880,095 to 6,647,351 as reported by the 1990 federal census. Although North
Carolina is the tenth largest State in population, it is primarily a rural
state, having only five municipalities with populations in excess of 100,000.

     The labor force has undergone significant change during recent years. The
State has moved from an agricultural to a service and goods producing economy.
Those persons displaced by farm mechanization and farm consolidations have, in
large measure, sought and found employment in other pursuits. Due to the wide
dispersion of non-agricultural employment, the people have been able to
maintain, to a large extent, their rural habitation practices. During the
period 1980 to 1992, the State labor force grew about 22% (from 2,855,200 to
3,487,500). Per capita income during the period 1980 to 1990 grew from $7,999
to $16,203, an increase of 102.6%.

     The current economic profile of the State consists of a combination of
industry, agriculture and tourism. As of May 1993, the State was reported to
rank tenth among the states in non-agricultural employment and eighth in
manufacturing employment. Employment indicators have varied somewhat in the
annual periods since June of 1989, but have demonstrated an upward trend since
1991. The following table reflects the fluctuations in certain key employment
categories.

     The adjusted unemployment rate in June 1993 was 5.4% of the labor force,
as compared with an unemployment rate of 7.0% nationwide.

     Gross agricultural income in 1992 was $5.26 billion, including
approximately $5,181,695,000 income from commodities. As of 1992, the State
was tenth in the nation in gross agricultural income. According to the State
Commissioner of Agriculture, in 1992, the State ranked first in the nation in
the production of flue-cured tobacco, total tobacco, turkeys and sweet
potatoes; second in the value of poultry and poultry products, in the
production of cucumbers for pickles and in trout production; fourth in
commercial broilers, strawberries and peanuts; sixth in burley tobacco and
hogs; and seventh in the number of chickens (excluding broilers), pecans and
apples.

     The diversity of agriculture in North Carolina and a continuing push in
marketing efforts have protected farm income from some of the wide variations
that have been experienced in other states where most of the agricultural
economy is dependent on a small number of agricultural commodities. North
Carolina is the third most diversified agricultural state in the nation.

     Nevertheless, tobacco production is the second leading source of
agricultural income in the State, accounting for 20.3% of gross agricultural
income. Tobacco farming in North Carolina has been and is expected to continue
to be affected by major Federal legislation and regulatory measures regarding
tobacco production and marketing and by international competition. Measures
adverse to tobacco farming could have negative effects on farm income and the
North Carolina economy generally. The largest single source for agricultural
income in the State is poultry and eggs, which accounted for revenues of
approximately $1.6 billion in 1992 and 31% of gross agricultural income.

     The number of farms has been decreasing; in 1993 there were approximately
59,000 farms in the State (down from approximately 72,000 in 1987, a decrease
of about 18% in six years). However, a strong agribusiness sector also
supports farmers with farm inputs (fertilizer, insecticide, pesticide and farm
machinery) and processing of commodities produced by farmers (vegetable
canning and cigarette manufacturing).

     The State Department of Commerce, Travel and Tourism Division statistics
office reports that in 1992 approximately $7.8 billion was spent on tourism in
the State, with 1993 revenues from tourism expected to exceed $8 billion. The
statistics office estimates a 6% annual average revenue growth rate in the
tourism industry. In 1991, traveler expenditures directly generated more than
155,000 jobs within the State, 5.1 percent of total nonagricultural employment
in that year.

     Bond Ratings. Currently, Moody's rates North Carolina general obligation
bonds as Aaa and Standard & Poor's rates such bonds as AAA. Standard & Poor's
also reaffirmed its stable outlook for the State in October 1993.

     Standard & Poor's reports that North Carolina's rating reflects the
State's strong economic characteristics, sound financial performance, and low
debt levels.

     The Sponsor believes the information summarized above describes some of
the more significant events relating to the North Carolina Trust. The sources
of this information are the official statements of issuers located in North
Carolina, State agencies, publicly available documents, publications of rating
agencies and news reports of statements by State officials and employees and
by rating agencies. The Sponsor and its counsel have not independently
verified any of the information contained in the official statements and other
sources and counsel have not expressed any opinion regarding the completeness
or materiality of any matters contained in this Prospectus other than the tax
opinions set forth below under North Carolina Taxes.

     TAX STATUS. For a discussion of the Federal tax status of income earned
on North Carolina Quality Trust Units, see "Other Matters--Federal Tax
Status". The portfolio of the North Carolina Quality Trust consists of bonds
issued by the State of North Carolina or municipalities, authorities or
political subdivisions thereof (the "Bonds").

     In the opinion of Hunton & Williams, special counsel to the Fund for
North Carolina tax matters, under existing North Carolina law:

     Upon the establishing of the North Carolina Quality Trust and the Units
thereunder:

     (1)   The North Carolina Quality Trust is not an "association" taxable as
        a corporation under North Carolina law with the result that income of
        the North Carolina Quality Trust will be deemed to be income of the
        Unitholders.

     (2)   Interest on the Bonds that is exempt from North Carolina income tax
        when received by the North Carolina Quality Trust will retain its
        tax-exempt status when received by the Unitholders.

     (3)   Unitholders will realize a taxable event when the North Carolina
        Quality Trust disposes of a Bond (whether by sale, exchange,
        redemption or payment at maturity) or when a Unitholder redeems or
        sells his Units (or any of them), and taxable gains for Federal income
        tax purposes may result in gain taxable as ordinary income for North
        Carolina income tax purposes. However, when a Bond has been issued
        under an act of the North Carolina General Assembly that provides that
        all income from such Bond, including any profit made from the sale
        thereof, shall be free from all taxation by the State of North
        Carolina, any such profit received by the North Carolina Quality Trust
        will retain its tax-exempt status in the hands of the Unitholders.

     (4)   Unitholders must amortize their proportionate shares of any premium
        on a Bond. Amortization for each taxable year is accomplished by
        lowering the Unitholder's basis (as adjusted) in his Units with no
        deduction against gross income for the year.

     (5)   The Units are exempt from the North Carolina tax on intangible
        personal property so long as the corpus of the North Carolina Quality
        Trust remains composed entirely of Bonds or, pending distribution,
        amounts received on the sale, redemption or maturity of the Bonds and
        the Trustee periodically supplies to the North Carolina Department of
        Revenue at such times as required by the Department of Revenue a
        complete description of the North Carolina Quality Trust and also the
        name, description and value of the obligations held in the corpus of
        the North Carolina Quality Trust.

     The opinion of Hunton & Williams is based, in part, on the opinion of
Chapman and Cutler regarding Federal tax status.

<F1> 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".
<F2> 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.
<F3> 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".

OREGON QUALITY TRUST

      GENERAL. The Oregon Quality Trust consists of 10 issues of Securities.
Three of the Bonds in the Oregon Quality 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 Oregon Quality Trust) as follows: General Obligations, 3 (29%); Retail
Electric/Gas, 3 (20%); Higher Education, 1 (17%); Certificates of
Participation, 1 (16%); Public Building, 1 (15%) and Transportation, 1 (3%).
No Bond issue has received a provisional or conditional rating.

     SPECIAL CONSIDERATIONS. Oregon's nonagricultural employment growth in
1988 exceeded the United States' rate for the third consecutive year. While
the decade of 1970 to 1980 marked a time of rapid growth, the early years of
the 1980s were a period of retrenchment and job losses. Oregon finally
regained pre-recessionary nonagricultural employment levels (compared to 1979)
in 1986, and continued growing quickly through 1988.

     The service and retail and wholesale trade sectors have contributed most
of the job gains. In 1979, services comprised 18 percent and retail and
wholesale trade 24 percent of total nonagricultural employment. Manufacturing
contributed 22 percent. By 1988, services grew to 23 percent, retail and
wholesale trade rose to 25 percent, but manufacturing shrank to 19 percent.
During the period 1979 to 1988, services and retail and wholesale trade added
110,000 jobs while manufacturing jobs dropped by 14,000.

     Total state population and personal income followed similar trends. From
1975 to 1980, both population and personal income exceeded national growth
rates. In the late 1970s, Oregon's populaton grew at a rate of two to three
times the national average. The early 1980s marked a reversal of this trend,
and population and personal income growth slowed to rates below the national
average.

     Recent economic trends have been favorable. In early 1987, the State's
unemployment rate dipped below the national rate, and State employment growth
exceeded the national average. Increased demand for wood products, primary
metals, and machinery and rapidly growing nonmanufacturing sectors helped push
the growth rates upward.

     A mild climate, varied topography and rich soil support the nearly 100
agricultural commodities grown in Oregon and valued in terms of gross farm
sales at over $2.3 billion in 1988. Much of this agricultural activity occurs
in the Willamette River Valley in the western portion of the State. This
valley also contains most of the State's population and much of the
manufacturing activity.

     Portland, located at the confluence of the Columbia and Willamette
Rivers, remains Oregon's largest city and the hub of economic activity. The
greater Portland area is a highly diversified manufacturing center. It is also
the home of the Port of Portland, a significant seaport for trade between the
western United States and the Pacific Rim nations.

     Outside the Willamette Valley, those areas not devoted primarily to
agriculture rely on the wood products industry and tourism. Although the wood
products industry is still sensitive to economic fluctuations, increased
automation and improved management are enabling the industry to reach all-time
high production levels with fewer workers.

     Oregon's economy grew moderately in the two decades immediately following
World War II. From 1950 to 1970, nonagricultural employment growth averaged
2.7 percent per year. In the 1970s, however, the State experienced rapid
growth as population increased and economic diversification continued.
Oregon's growth significantly outpaced the national average: from 1975 to 1980
nonagricultural employment growth averaged 6.1 percent per year and per capita
income rose above the U.S. average.

     The early 1980s recessions hit Oregon hard. In 1982, nonagricultural
employment fell by 5.7 percent with much of the loss from the wood products
industry. Oregon remains slightly more sensitive to economic cycles than the
national average due to the forest products component of its economy. Although
recessionary periods continue to be somewhat more pronounced in Oregon than in
the nation as a whole, the higher proportion of nonmanufacturing jobs and
restructuring of the lumber and wood industry has provided more stability.

                          Oregon QUALITY-- Series 52                        55

     While the high technology industries added a significant number of jobs
in the late 1970s and early 1980s, the State has followed national trends and
lost jobs as a result of a slump in the semi-conductor, electronics and
instruments industries. In recent years, these industries have stabilized and
started adding workers.

     The high interest rates experienced early in the 1980s had a significant
impact on certain sectors of the Oregon economy. The recession-sensitive wood
products, housing, and construction industries were particularly hard hit.
Rural counties of eastern and southern Oregon which depend on one or a
combination of these industries experienced the greatest impact. Many of these
counties have since diversified more and have benefited significantly from
improved tourism traffic. In urban areas generally, and in Portland in
particular, the diverse economic base has given a measure of insulation from
the impacts of the recession.

     By 1984, the State began to recover and experienced a higher employment
growth rate at 4.2 percent, but this rate was still lower than the U.S. rate.
The State finally surpassed prerecessionary employment levels in 1986 and has
recently been growing faster than the U.S. average.

     Tourism has been strong throughout the 1980s, due in part to the
plentiful supplies of relatively low-cost automobile fuel and improved
national economy. Oregon's wood products industry is undergoing a permanent
restructuring, as many mills have automated and improved their productivity
greatly. The State has committed itself to greater diversification of the
economy by pursuing more foreign trade in the considerable markets of the
Pacific Rim countries.

     Between 1979 and 1988, total nonagricultural wage and salary employment
in Oregon rose from 1,056,200 to 1,152,300, an increase of 9.1 percent. During
this period, however, employment exhibited three different trends.

     In 1979, a dramatic rise in interest rates severely hurt credit-sensitive
industries such as construction and lumber and wood products and plunged the
Nation into the worst recession since the 1930s. Oregon's housing-dependent
economy was especially hard hit. Between 1979 and 1982, wage and salary
employment plummeted by 9 percent to 960,000, a loss of 95,400 jobs.

     While the severity of the recession eliminated many jobs, both in
manufacturing (42,800) and non-manufacturing (52,600), it also caused interest
rates and the inflation rate eventually to drop significantly. This
improvement, plus more stimulative federal monetary and fiscal policies, set
the stage for another period of economic expansion beginning in early 1983. In
the six year period between 1982 and 1988, Oregon's wage and salary employment
increased by 20 percent to reach a new all-time high of 1,152,300, a gain of
191,500 jobs.

     The current expansion differs from previous recovery periods. During the
last six years, manufacturing employment has risen by 28,600 jobs but is still
about 14,200 below its 1979 pre-recession peak of 228,500. This slow rate of
recovery largely reflects increased competition from foreign imports,
automation and increased productivity. In the first half of the 1980s, the
rising foreign exchange value of the dollar made U.S. exported goods more
expensive overseas, while foreign imports became cheaper to U.S. consumers.
Although the dollar's exchange value has been falling since 1985, imports have
captured a greater share of U.S. markets. Manufacturing firms in Oregon and
the Nation have responded by reducing their costs, restructuring their
operations and automating production processes wherever possible. In some
cases, these efficiencies have resulted in few jobs even though production
volumes have recovered and reached new all-time highs. Oregon's primary
industry, lumber and wood products, is one such example.

     About 85 percent of the 191,500 new wage and salary jobs added in the
1982-1988 period came in non-manufacturing. Although every non-manufacturing
industrial category except mining, communications and utilities increased
employment, the service and trade industries accounted for eight out of every
ten new non-manufacturing jobs. Job growth was especially strong in food
stores, eating and drinking places, health care and business services.

     In its 1989 Regular Session, the Oregon Legislature approved General Fund
appropriations totaling $4,585,476,617 for the 1989-1991 biennium. This is a
22 percent increase compared to estimated 1987-1989 expenditures.

     A complete analysis of State General Fund finances for 1989-1991 will not
be available until after the impact of all legislative actions affecting
expenditures are compiled.

     The following is a summary of the September 1, 1989 quarterly Economic
and Revenue Forecast required by ORS 291.342.

     The much heralded "soft landing" scenario appears the most likely course
for the U.S. economy over the short term. Such a scenario implies an extended
period of lower growth, an easing of inflationary pressures, and little
improvement in the unemployment rate. The greatest short-term risk to the soft
landing is overreaction by the Federal Reserve in easing credit. Easing would
stimulate growth and a rise in inflation in the short-run, which would later
induce Federal tightening and plunge the economy into a recession.

     In late 1989 and early 1990, the anticipated soft landing will reduce
employment growth in Oregon and the U.S. Overall, Oregon employment is
expected to increase by 13,600 over the next year (second quarter to second
quarter), and 7,700 over the following year. This means that, relative to the
May forecast, 3,100 fewer jobs will be generated in the next year. Still,
employment growth in Oregon is expected to exceed gains nation-wide in 1989.

     The primary reasons for the slowdown in Oregon are: (1) expected timber
supply reductions, which will directly reduce lumber and wood products and
transportation employment; (2) a gradual slowdown in construction, as
apartment vacancy rates begin to rise and Oregon's population growth rate
begins to slow; and (3) the ending of Oregon's retail trade boom, which
brought increased competition in the form of many new retail chains and stores
to Oregon.

     Total Oregon employment increased by 8,400 in the second quarter, 1,200
less than anticipated in the May 1989 forecast. Manufacturing employment
increased by 700, while nonmanufacturing employment increased by 7,700.

     Total General Fund collections in 1987-1989 were $49.4 million above the
May 15 forecast and $211.4 million above the estimate made at the close of the
1987 Regular session. Both Corporate Excise and income tax receipts and all
other General Fund revenues exceeded the close of Regular Session estimate by
more than two percent. Therefore, ORS 291.349 (known as the "two percent
kicker" law) requires that all unanticipated revenues be returned to the
taxpayers. Corporate income taxpayers will receive a 19.7 percent credit on
their tax year 1989 liabilities to return the $36.2 million in unanticipated
Corporate Excise and Income Tax revenues. Personal income taxpayers will
receive a 9.8 percent credit on their tax year 1989 liabilities to return
unanticipated receipts of $175.2 million from all noncorporate General Fund
revenue sources.

     More than 40 bills passed by the 1989 Legislature changed expected
General Fund revenue receipts. Altogether, these bills raised expected
1989-1991 receipts by $25.4 million, with expected Personal Income Taxes
increasing $29.9 million. Corporate Excise and Income taxes increasing by $4.9
million, and all other General Fund revenues decreasing by $9.4 million. The
Legislature appropriated $4,585.5 million for the 1989-1991 period, leaving an
ending balance of $121.7 million.

     The September General Fund revenue forecast anticipates that the state
will receive $9.6 million more during 1989-1991 than was anticipated at the
close of the 1989 Regular Session. This, combined with the surge in 1987-1989
revenues, pushes the expected 1989-1991 ending balance to $181.0 million.

     The September Personal Income Tax forecast for 1989-1991 has been
increased by $39.8 million because the high final payments individuals made
during the 1989 filing season are expected to continue. The Corporate Excise
and Income Tax forecast has been lowered by $10.2 million, again reflecting
receipts during the critical April filing season. Expected Insurance Tax
receipts have been decreased by $21.4 million because of an unanticipated
weakening in commercial insurance premiums.

     The foregoing information constitutes only a brief summary of some of the
financial difficulties which may impact certain issuers of Bonds and does not
purport to be a complete or exhaustive description of all adverse conditions
to which the issuers in the Oregon Quality Trust are subject. Additionally,
many factors including national economic, social and environmental policies
and conditions, which are not within the control of the issuers of Bonds,
could affect or could have an adverse impact on the financial condition of the
State and various agencies and political subdivisions located in the State.
The Sponsor is unable to predict whether or to what extent such factors or
other
 <PAGE>
                          Oregon QUALITY-- Series 52                        57
factors may affect the issuers of Bonds, the market value or marketability of
the Bonds or the ability of the respective issuers of the Bonds acquired by
the Oregon Quality Trust to pay interest on or principal of the Bonds.

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

     The assets of the Oregon Trust will consist of interest-bearing
obligations issued by or on behalf of the State of Oregon (the "State") or
counties, municipalities, authorities or political subdivisions thereof (the
"Oregon Bonds") or by the Commonwealth of Puerto Rico, Guam and the United
States Virgin Islands (the "Possession Bonds") (collectively, the "Bonds").
Neither the Sponsor nor its counsel have independently examined the Bonds to
be deposited in and held in the Oregon Quality Trust. However, although no
opinion is expressed herein regarding such matters, it is assumed that: (i)
the Bonds were validly issued; (ii) the interest thereon is excludible from
gross income for federal income tax purposes; and (iii) interest on the Bonds,
if received directly by an Oregon Unitholder, would be exempt from the Oregon
income tax applicable to individuals (the "Oregon Personal Income Tax").

     In the opinion of Chapman and Cutler, Special Counsel to the Fund for
Oregon tax matters, under existing Oregon law and based on the assumptions set
forth above:

     The Oregon Quality Trust is not an association taxable as a corporation
and based upon an administrative rule of the Oregon State Department of
Revenue, each Oregon Unitholder of the Oregon Quality Trust will be
essentially treated as the owner of a pro rata portion of the Oregon Quality
Trust and the income of such portion of the Oregon Quality Trust will be
treated as the income of the Oregon Unitholder for Oregon Personal Income Tax
purposes;

     Interest on the Bonds which is exempt from the Oregon Personal Income Tax
when received by the Oregon Quality Trust, and which would be exempt from the
Oregon Personal Income Tax if received directly by an Oregon Unitholder, will
retain its status as exempt from such tax when received by the Oregon Quality
Trust and distributed to an Oregon Unitholder;

     To the extent that interest derived from the Oregon Quality Trust by an
Oregon Unitholder with respect to the Possession Bonds is excludable from
gross income for Federal income tax purposes pursuant to 48 U.S.C. Section
745, 48 U.S.C. Section 1423a and 48 U.S.C. Section 1403, such interest will
not be subject to the Oregon Personal Income Tax. Each Oregon Unitholder of
the Oregon Quality Trust will recognize gain or loss for Oregon Personal
Income Tax purposes if the Trustee disposes of a bond (whether by redemption,
sale or otherwise) or if the Oregon Unitholder redeems or sells Units of the
Oregon Quality Trust to the extent that such a transaction results in a
recognized gain or loss to such Oregon Unitholder for Federal income tax
purposes; and

     The Oregon Personal Income Tax does not permit a deduction of interest
paid or incurred on indebtedness incurred or continued to purchase or carry
Units in the Oregon Quality Trust, the interest on which is exempt from such
Tax.

     Investors should consult their tax advisors regarding collateral tax
consequences under Oregon law relating to the ownership of the Units,
including, but not limited to, the calculation of "net pension income" tax
credits for retirees and the applicability of other Oregon taxes.

     We have not examined any of the Bonds to be deposited and held in the
Oregon Quality Trust or the proceedings for the issuance thereof or the
opinions of bond counsel with respect thereto and therefore express no opinion
as to the exemption from the Oregon Personal Income Tax of interest on the
Bonds if received directly by an Oregon Unitholder. In addition, prospective
purchasers subject to the Oregon corporate income tax should be advised that
for purposes of the Oregon Corporate Income (Excise) Tax, interest on the
Bonds received by the Oregon Quality Trust and distributed to an Oregon
Unitholder subject to such tax will be added to the corporate Oregon
Unitholder's federal taxable income and therefore will be taxable.

<F1> 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".
<F2> 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.
<F3> 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,

"U/R" indicates that such rating is under review by Moody's Investors Service,
Inc. The Sponsor believes that such Revenue Bonds issued by Oregon State
Health, Housing, Educational and Cultural Facilities Authority and insured by
MBIA have such credit characteristics that the rating ultimately given by
Moody's Investors Service, Inc. will be Aaa; and such Elderly and Disabled
Housing General Obligation Bonds issued by Oregon State have such credit
characteristics that the rating ultimately given by Moody's Investors Service,
Inc. will be Aa.

60                           Notes to Portfolios

NOTES TO PORTFOLIOS:
AS OF THE DATE OF DEPOSIT: MAY 19, 1994
   
(1) All Securities are represented by "regular way" or "when issued"
     contracts for the performance of which an irrevocable letter of credit,
     obtained from an affiliate of the Trustee, has been deposited with the
     Trustee. At the Date of Deposit, Securities may have been delivered to
     the Sponsor pursuant to certain of these contracts; the Sponsor has
     assigned to the Trustee all of its right, title and interest in and to
     such Securities. Contracts to acquire Securities were entered into during
     the period from September 2, 1993 to May 18, 1994. These Securities have
     expected settlement dates ranging from May 19, 1994 to June 21, 1994 (see
     "Unitholder Explanations").
    
(2)  All ratings are by Standard & Poor's Corporation unless otherwise
     indicated. "*" indicates that the rating of the Bond is by Moody's
     Investors Service, Inc. The ratings represent the latest published
     ratings by the respective ratings agency or, if not published, represent
     private letter ratings or those ratings expected to be published by the
     respective ratings agency. "Y" indicates that such rating is contingent
     upon physical receipt by the respective ratings agency of a policy of
     insurance obtained by the issuer of the bonds involved and issued by the
     Preinsured Bond Insurer named in the bond's title. A commitment for
     insurance in connection with these bonds has been issued by the
     Preinsured Bond Insurer named in the bond's title. "N/R" indicates that
     the applicable rating service did not provide a rating for that
     particular Security. For a brief description of the rating symbols and
     their related meanings, see "Other Matters-- Description of Securities
     Ratings".
(3)  There is shown under this heading the year in which each issue of Bonds
     is initially or currently callable and the call price for that year. Each
     issue of Bonds continues to be callable at declining prices thereafter
     (but not below par value) except for original issue discount bonds which
     are redeemable at prices based on the issue price plus the amount of
     original issue discount accreted to redemption date plus, if applicable,
     some premium, the amount of which will decline in subsequent years.
     "S.F." indicates a sinking fund is established with respect to an issue
     of Bonds. Redemption pursuant to call provisions generally will, and
     redemption pursuant to sinking fund provisions may, occur at times when
     the redeemed bonds have an offering side valuation which represents a
     premium over par. Certain Bonds may be subject to redemption without
     premium prior to the date shown pursuant to extraordinary optional or
     mandatory redemptions if certain events occur. Single family mortgage
     revenue bonds and housing authority bonds are most likely to be called
     subject to such provisions, but other bonds may have similar call
     features. Notwithstanding any provisions to the contrary, certain bond
     issuers have in the past and others may in the future attempt to redeem
     Bonds prior to their initially scheduled call dates and at prices which
     do not include any premiums. For a general discussion of certain of these
     events, see "Unitholder Explanations--Bond Redemptions". To the extent
     that the Securities were deposited in a Trust at a price higher than the
     price at which they are redeemed, this will represent a loss of capital
     when compared with the original Public Offering Price of the Units.
     Conversely, to the extent that the Bonds were acquired at a price lower
     than the redemption price, this will represent an increase in capital
     when compared with the original Public Offering Price of the Units.
     Distributions will generally be reduced by the amount of the income which
     would otherwise have been paid with respect to redeemed Securities and
     there will be distributed to Unitholders the principal amount and any
     premium received on such redemption. The Estimated Current Return and
     Estimated Long-Term Return in this event may be affected by such
     redemptions. For the Federal tax effect on Unitholders of such
     redemptions and resultant distributions, see paragraph <F2>under "Other
     Matters--Federal Tax Status".
(4)  Evaluation of Securities is made on the basis of current offering prices
     for the Securities. The offering prices are greater than the current bid
     prices of the Securities which is the basis on which Unit value is
     determined for purposes of redemption of Units (see "Unitholder
     Explanations--Public Offering--Offering Price").
(5)  Other information regarding the Bonds in each Trust, as of the Date of
     Deposit, is as follows:

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

     On the Date of Deposit, the offering side evaluations of the Securities
     in the IM-IT, IM-IT Intermediate, New Mexico IM-IT, Pennsylvania IM-IT,
     Kentucky Quality, North Carolina Quality and Oregon Quality Trusts were
     higher than the bid side evaluations of such Securities by 0.74%, 0.77%,
     0.74%, 0.76%, 0.73%, 0.77% and 0.76%, respectively, of the aggregate
     principal amounts of such Securities.
     "#" indicates that such Bond was issued at an original issue discount.
     The tax effect of Bonds issued at an original issue discount is described
     in "Other Matters--Federal Tax Status".
    
   
(6)  This Bond has been purchased at a deep discount from the par value
     because there is little or no stated interest income thereon. Bonds which
     pay no interest are normally described as "zero coupon" bonds. Over the
     life of bonds purchased at a deep discount the value of such bonds will
     increase such that upon maturity the holders of such bonds will receive
     100% of the principal amount thereof. Approximately 2%, 1%, 1% and 1% of
     the aggregate principal amount of the Securities in the IM-IT, IM-IT
     Intermediate Trust, New Mexico IM-IT Trust and Oregon Quality Trust,
     respectively, are "zero coupon" bonds.
    
(7)  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, at various times the Sponsor may
implement other programs under which the sales forces of Underwriters,
brokers, dealers, banks and/or others may be eligible to win other nominal
awards for certain sales efforts, or under which the Sponsor will reallow to
any such Underwriters, brokers, dealers, banks and/or others that sponsor
sales contests or recognition programs conforming to criteria established by
the Sponsor, or participate in sales programs sponsored by the Sponsor, an
amount not exceeding the total applicable sales charges on the sales generated
by such persons at the public offering price during such programs. Also, the
Sponsor in its discretion may from time to time pursuant to objective criteria
established by the Sponsor pay fees to qualifying underwriters, brokers,
dealers, banks or others for certain services or activities which are
primarily intended to result in sales of Units of the Trusts. Such payments
are made by the Sponsor out of its own assets, and not out of the assets of
the Trusts. These programs will not change the price Unitholders pay for their
Units or the amount that the Trusts will receive from the Units sold.
Approximately every eighteen months the Sponsor holds a business seminar which
is open to Underwriters that sell units of trusts it sponsors. The Sponsor
pays substantially all costs associated with the seminar, excluding
Underwriter travel costs. Each Underwriter is invited to send a certain number
of representatives based on the gross number of units such firm underwrites
during a designated time period.

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

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

     COMPENSATION OF SPONSOR AND EVALUATOR. The Sponsor will not receive any
fees in connection with its activities relating to the Fund. However, American
Portfolio Evaluation Services, a division of Van Kampen Merritt Investment
Advisory Corp., which is a wholly-owned subsidiary corporation of the Sponsor,
will receive an annual supervisory fee as indicated under "Summary of
Essential Financial Information" for providing portfolio supervisory services
for the Fund. Such fee (which is based on the number of Units outstanding in
each Trust on January 1 of each year) may exceed the actual costs of providing
such supervisory services for this Fund, but at no time will the total amount
received for portfolio supervisory services rendered to Insured Municipals
Income Trust and Investors' Quality Tax-Exempt Trust, Multi-Series 1 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
 <PAGE>
                             Trust Administration                           69
Explanations--Public Offering--Reports Provided"). The Trustee is required to
keep a certified copy or duplicate original of the Trust Agreement on file in
its office available for inspection at all reasonable times during the usual
business hours by any Unitholder, together with a current list of the
Securities held in the Fund.

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

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

     TRUSTEE'S FEE. For its services the Trustee will receive a fee based on
the aggregate outstanding principal amount of Securities in each Trust as of
the opening of business on January 2 and July 2 of each year as set forth
under "Per Unit Information" for the applicable Trust. During the first year
the Trustee may agree to reduce its fee (and to the extent necessary pay
miscellaneous expenses of a Trust) as stated under "Per Unit Information" for
the applicable Trust. The Trustee's fees are payable monthly on or before the
fifteenth day of each month from the Interest Account of each Trust to the
extent funds are available and then from the Principal Account of each Trust,
with such payments being based on each Trust's portion of such expenses. Since
the Trustee has the use of the funds being held in the Principal and Interest
Accounts for future distributions, payment of expenses and redemptions and
since such Accounts are non-interest bearing to Unitholders, the Trustee
benefits thereby. Part of the Trustee's compensation for its services to each
Trust is expected to result from the use of these funds. Such fees may be
increased without approval of the Unitholders by amounts not exceeding
proportionate increases under the category "All Services Less Rent of Shelter"
in the Consumer Price Index published by the United States Department of Labor
or, if such category is no longer published, in a comparable category. The
Trustee's fees will not be increased in future years in order to make up any
reduction in the Trustee's fees described under "Per Unit Information" for the
applicable Trust. For a discussion of the services rendered by the Trustee
pursuant to its obligations under the Trust Agreement, see "Unitholder
Explanations--Public Offering--Reports Provided" and "Trustee" above.

     PORTFOLIO ADMINISTRATION. The Trustee is empowered to sell, for the
purpose of redeeming Units tendered by any Unitholder, and for the payment of
expenses for which funds may not be available, such of the Bonds designated by
the Evaluator as the Trustee in its sole discretion may deem necessary. The
Evaluator, in designating such Securities, will consider a variety of factors,
including (a) interest rates, (b) market value and (c) marketability. The
Sponsor, in connection with the Quality Trusts, may direct the Trustee to
dispose of Securities upon default in payment of principal or interest,
institution of certain legal proceedings, default under other documents
adversely affecting debt service, default in payment of principal or interest
on other obligations of the same issuer, decline in projected income pledged
for debt service on revenue bonds or decline in price or the occurrence of
other market or credit factors, including advance refunding (i.e., the
issuance of refunding securities and the deposit of the proceeds thereof in
trust or escrow to retire the refunded securities on their respective
redemption dates), so that in the opinion of the Sponsor the retention of such
Securities would be detrimental to the interest of the Unitholders. 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
 <PAGE>
70                           Trust Administration
determined by the Trustee to be in the best interests of the Unitholders or if
there is no alternative, the Trustee is not empowered to sell Bonds from an
Insured Trust which are in default in payment of principal or interest or in
significant risk of such default and for which value has been attributed for
the insurance obtained by such Insured Trust. Because of such restrictions on
the Trustee under certain circumstances, the Sponsor may seek a full or
partial suspension of the right of Unitholders to redeem their Units in an
Insured Trust. See "Unitholder Explanations--Public Offering-- Redemption of
Units". The Sponsor is empowered, but not obligated, to direct the Trustee to
dispose of Bonds in the event of an advanced refunding.

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

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

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

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

     INSURANCE PREMIUMS. The cost of the portfolio insurance obtained by the
respective Trusts, if any, is that amount shown in footnote (5) in "Notes to
Portfolios", so long as such Trust retains the Bonds. Premiums, which are
obligations of each Insured Trust, are payable monthly by the Trustee on
behalf of the respective Trust. As Bonds in the portfolio of an Insured Trust
are redeemed by their respective issuers or are sold by the Trustee, the
amount of the premium will be reduced in respect of those Bonds no longer
owned by and held in such Trust. If the Trustee exercises the right to obtain
permanent insurance, the premiums payable for such permanent insurance will be
paid solely from the proceeds of the sale of the related Bonds. The premiums
for such permanent insurance with respect to each Bond will decline over the
life of the Bond. A Trust does not incur any expense for Preinsured Bond
insurance, since the premium or premiums for such insurance have been paid by
the issuer or the Sponsor prior to the deposit of such Preinsured Bonds in a
Trust. Preinsured Bonds are not additionally insured by an Insured Trust.

     MISCELLANEOUS EXPENSES. The following additional charges are or may be
incurred by the Trusts: (a) fees of the Trustee for extraordinary services,
(b) expenses of the Trustee (including legal and auditing expenses) and of
counsel designated by the Sponsor, (c) various governmental charges, (d)
expenses and costs of any action taken by the Trustee to protect the Trusts
and the rights and interests of Unitholders, (e) indemnification of the
Trustee for any loss, liability or expenses incurred by it in the
administration of the Fund without negligence, bad faith or willful misconduct
on its part, (f) any special custodial fees payable in connection with the
sale of any of the Bonds in a Trust and (g) expenditures incurred in
contacting Unitholders upon termination of the Trusts.
 <PAGE>
                             Trust Administration                           71

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

GENERAL

     AMENDMENT OR TERMINATION. The Sponsor and the Trustee have the power to
amend the Trust Agreement without the consent of any of the Unitholders when
such an amendment is (a) to cure an ambiguity or to correct or supplement any
provision of the Trust Agreement which may be defective or inconsistent with
any other provision contained therein or (b) to make such other provisions as
shall not adversely affect the interest of the Unitholders (as determined in
good faith by the Sponsor and the Trustee), provided that the Trust Agreement
may not be amended to increase the number of Units issuable thereunder or to
permit the deposit or acquisition of securities either in addition to or in
substitution for any of the Securities initially deposited in the Fund, except
for the substitution of certain refunding securities for such Securities. In
the event of any amendment, the Trustee is obligated to notify promptly all
Unitholders of the substance of such amendment.
   
     A Trust may be terminated at any time by consent of Unitholders of 51% of
the Units of such Trust then outstanding or by the Trustee when the value of
such Trust, as shown by any semi-annual evaluation, is less than that
indicated under "Summary of Essential Financial Information". A Trust will be
liquidated by the Trustee in the event that a sufficient number of Units not
yet sold are tendered for redemption by the Underwriters, including the
Sponsor, so that the net worth of such Trust would be reduced to less than 40%
of the initial principal amount of such Trust. If a Trust is liquidated
because of the redemption of unsold Units by the Underwriters, the Sponsor
will refund to each purchaser of Units the entire sales charge paid by such
purchaser. The Trust Agreement provides that each Trust shall terminate upon
the redemption, sale or other disposition of the last Security held in such
Trust, but in no event shall it continue beyond the end of the year preceding
the fiftieth anniversary of the Trust Agreement in the case of an IM-IT or a
State Trust or beyond the end of the year preceding the twentieth anniversary
of the Trust Agreement in the case of an IM-IT Limited Maturity, IM-IT
Intermediate and IM-IT Short Intermediate Trust. In the event of termination
of the Fund or any Trust, written notice thereof will be sent by the Trustee
to each Unitholder of such Trust at his address appearing on the registration
books of the Fund maintained by the Trustee. Within a reasonable time
thereafter the Trustee shall liquidate any Securities then held in such Trust
and shall deduct from the funds of such Trust any accrued costs, expenses or
indemnities provided by the Trust Agreement, including estimated compensation
of the Trustee and costs of liquidation and any amounts required as a reserve
to provide for payment of any applicable taxes or other governmental charges.
The sale of Securities in the Trust upon termination may result in a lower
amount than might otherwise be realized if such sale were not required at such
time. For this reason, among others, the amount realized by a Unitholder upon
termination may be less than the principal amount or par amount of Securities
represented by the Units held by such Unitholder. The Trustee shall then
distribute to each Unitholder his share of the balance of the Interest and
Principal Accounts. With such distribution the Unitholder shall be furnished a
final distribution statement of the amount distributable. At such time as the
Trustee in its sole discretion shall determine that any amounts held in
reserve are no longer necessary, it shall make distribution thereof to
Unitholders in the same manner.
    
     Notwithstanding the foregoing, in connection with final distributions to
Unitholders of an Insured Trust, it should be noted that because the portfolio
insurance obtained by an Insured Trust is applicable only while Bonds so
insured are held by such Trust, the price to be received by such Trust upon
the disposition of any such Bond which is in default, by reason of nonpayment
of principal or interest, will not reflect any value based on such insurance.
Therefore, in connection with any liquidation, it shall not be necessary for
the Trustee to, and the Trustee does not currently intend to, dispose of any
Bond or Bonds if retention of such Bond or Bonds, until due, shall be deemed
to be in the best interest of Unitholders, including, but not limited to,
situations in which a Bond or Bonds so insured are in default and situations
in which a Bond or Bonds so insured have deteriorated market prices resulting
from a significant risk of default. Since the Preinsured Bonds will reflect
the value of the related insurance, it is the present intention of the Sponsor
not to direct the Trustee to hold any of such Preinsured Bonds after the date
of termination. All proceeds received, less applicable expenses, from
insurance on defaulted Bonds not disposed of at the date of termination will
ultimately be distributed to Unitholders of record as of such date of
termination as soon as practicable
 <PAGE>
72                           Trust Administration
after the date such defaulted Bond or Bonds become due and applicable
insurance proceeds have been received by the Trustee.

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

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

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

     UNIT DISTRIBUTION. During the initial offering period, Units will be
distributed to the public by Underwriters, broker-dealers and others (see
"Underwriting") at the Public Offering Price, plus Purchased Interest, plus
interest accrued but unpaid from the First Settlement Date to the date of
settlement as described above under "Unitholder Explanations--Purchased and
Accrued Interest--Accrued Interest". Upon the completion of the initial
offering, Units repurchased in the secondary market, if any, may be offered by
this Prospectus at the secondary Public Offering Price, plus Purchased
Interest plus interest accrued to the date of settlement in the manner
described.
   
     The Sponsor intends to qualify the Units for sale in a number of states.
Broker-dealers or others will be allowed a concession or agency commission in
connection with the distribution of Units during the initial offering period
of $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 or a State Trust,
$30.00 per Unit for less than 100 Units, $36.00 per Unit for any single
transaction of 100 to 249 Units, $38.00 per Unit for any single transaction of
250 to 499 Units, $39.00 per Unit for any single transaction of 500 to 999
Units and $39.00 per Unit for any single transaction of 1,000 or more Units,
provided that such Units are acquired either from the Sponsor (in the case of
dealer transactions) or through the Sponsor (in the case of transactions
involving brokers or others). The increased concession or agency commission is
a result of the discount given to purchasers for quantity purchases. See
"Unitholder Explanations--Public Offering--General". Certain commercial banks
are making Units of the Fund available to their customers on an agency basis.
A portion of the sales charge paid by these customers (equal to the agency
commission referred to above) is retained by or remitted to the banks. Under
the Glass-Steagall Act, banks are prohibited from underwriting Units of the
Fund; however, the Glass-Steagall Act does permit certain agency transactions
and the banking regulators have not indicated that these particular agency
transactions are not permitted under such Act. In addition, state securities
laws on this issue may differ from the interpretations of federal law
expressed herein and banks and financial institutions may be required to
register as dealers pursuant to state law. Any quantity discount (see
"Unitholder Explanations--Public Offering-- General") provided to investors
will be borne by the selling dealer or agent. For secondary market
transactions, such concession or agency commission will amount to 70% of the
applicable sales charge as determined using the table found in "Unitholder
Explanations--Public Offering".
    
     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.
 <PAGE>
                             Trust Administration                           73

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

     SPONSOR AND UNDERWRITER COMPENSATION. The Underwriters will receive a
gross sales commission equal to that percentage of the Public Offering Price
of the Units (excluding Purchased Interest) as indicated under "Unitholder
Explanations--Public Offering--Offering Price" less any reduced sales charges
for quantity purchases as described under "Unitholder Explanations--Public
Offering--General".
   
     The Sponsor will receive from the Underwriters the excess of such gross
sales commission over $35.00, $29.00, $27.00, $22.00 and $35.00 per Unit of
any IM-IT, IM-IT Limited Maturity, IM-IT Intermediate, IM-IT Short
Intermediate and other Insured Trusts, respectively, as of the Date of
Deposit. In connection with quantity sales to purchasers of any IM-IT or State
Trust the Underwriters will receive from the Sponsor commissions totalling
$37.00 per Unit for any single transaction of 100 to 249 Units, $39.00 per
Unit for any single transaction of 250 to 499 Units, $40.00 per Unit for any
single transaction of 500 to 999 Units and $39.00 per Unit for any single
transaction of 1,000 or more Units. In connection with quantity sales to
purchasers of any Pennsylvania IM-IT Trust the Underwriters will receive from
the Sponsor commissions totalling $35.00 per Unit for any single transaction
of 100 to 249 Units, $36.00 per Unit for any single transaction of 250 to 499
Units, $37.00 per Unit for any single transaction of 500 to 999 Units and
$38.00 per Unit for any single transaction of 1,000 or more Units. In
addition, any Underwriter that sells a total of 25% or 1,500 Units, whichever
is greater, of any Pennsylvania IM-IT Trust will receive an additional $2.00
per each such Unit. 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. If Principal Financial Securities, Inc. commits (on the Date of
Deposit) to underwrite a total of 4,000 or more Units of this series of the
IM-IT, any other series of the IM-IT and/or any series of the Texas Insured
Municipals Income Trust during any calendar month, then Principal Financial
Securities, Inc. will receive an additional $1.00 per Unit for each of the
Units of such Trusts it commits to underwrite in said month. In addition, the
Sponsor will receive from the Managing Underwriters of the Oregon Quality
Trust (who underwrite 15% of the Trust or 1,000 Units of such Trust, whichever
is greater) the excess of such gross sales commission over $38.00 per Unit of
any such Trust, as of the Date of Deposit. Also, any such Managing Underwriter
that sells a total of 25% or 1,500 Units, whichever is greater, of any Oregon
Quality Trust will receive an additional $2.00 per each such Unit. In
addition, the Sponsor and J.J.B. Hilliard, W.L. Lyons, Inc. ("Hilliard,
Lyons") have entered into an agreement under which Hilliard, Lyons may receive
an additional $2.00 for each Unit of the Kentucky Quality Trust which it
underwrites, provided it underwrites a minimum of 400 Units of such Trust. See
"Unitholder Explanations--Public Offering--General". Further, each Underwriter
who underwrites 1,000 or more Units in any Trust will receive additional
compensation from the Sponsor of $1.00 for each Unit it underwrites. In
addition, the Sponsor and certain of the Underwriters will realize a profit or
the Sponsor will sustain a loss, as the case may be, as a result of the
difference between the price paid for the Securities by the Sponsor and the
cost of such Securities to a Trust (which is based on the determination by
Interactive Data Services, Inc. of the aggregate offering price of the
underlying Securities in such Trust on the Date of Deposit). See
"Underwriting" and "Portfolio" for the applicable Trust and "Notes to
Portfolios". The Sponsor and the Underwriters may also realize profits or
sustain losses with respect to Securities deposited in each Trust which were
acquired by the Sponsor from underwriting syndicates of which they were
members. The Sponsor has participated as sole underwriter or as manager or as
a member of the underwriting syndicates from which none of the aggregate
principal amount of the Securities in the portfolios of the Fund were
acquired. The Underwriters may further realize additional profit or loss
during the initial offering period as a result of the possible fluctuations in
the market value of the Securities in each Trust after the Date of Deposit,
since all proceeds received from purchasers of Units (excluding dealer
concessions or agency commissions allowed, if any) will be retained by the
Underwriters. Affiliates of an Underwriter are entitled to the same dealer
concessions or agency commissions that are available to the Underwriter.

     As stated under "Unitholder Explanations--Public Offering--Market for
Units", the Sponsor intends to, and certain of the other Underwriters may,
maintain a secondary market for the Units of the Fund. In so maintaining a
market, such person or persons will also realize profits or sustain losses in
the amount of any difference between the price at which Units are purchased
and the price at which Units are resold (which price is based on the bid
prices of the Securities in such Trust and includes a sales charge). In
addition, such person or persons will also realize profits or sustain losses
resulting from a redemption of such repurchased Units at a price above or
below the purchase price for such Units, respectively.

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.
 <PAGE>
76                              Other Matters

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

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

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

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

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

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

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

     At the respective times of issuance of the Bonds, opinions relating to
the validity thereof and to the exclusion of interest thereon from Federal
gross income are rendered by bond counsel to the respective issuing
authorities.

                                Other Matters                               77
Neither the Sponsor nor Chapman and Cutler has made any special review for the
Fund of the proceedings relating to the issuance of the Bonds or of the basis
for such opinions.

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

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

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

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

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

DESCRIPTION OF SECURITIES RATINGS*

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

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

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

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

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

     II. Nature of and provisions of the obligation.

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

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

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

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

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

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

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

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

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

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

*As published by the rating companies.

                                Other Matters                               79

     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 and Investors' Quality Tax-Exempt
   Trust, Multi-Series 221 (IM-IT, IM-IT Intermediate, New Mexico IM-IT,
   Pennsylvania IM-IT, Kentucky Quality, North Carolina Quality and Oregon
   Quality Trusts):

        We have audited the accompanying statements of condition and the
   related portfolios of Insured Municipals Income Trust and Investors'
   Quality Tax-Exempt Trust, Multi-Series 221 (IM-IT, IM-IT Intermediate,
   New Mexico IM-IT, Pennsylvania IM-IT, Kentucky Quality, North Carolina
   Quality and Oregon Quality Trusts) as of May 19, 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 and Investors' Quality Tax-Exempt Trust,
   Multi-Series 221 (IM-IT, IM-IT Intermediate, New Mexico IM-IT,
   Pennsylvania IM-IT, Kentucky Quality, North Carolina Quality and Oregon
   Quality Trusts) as of May 19, 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
     payment date on the Securities or the date of issuance thereof. The
     Trustee may advance to the Trust a portion of the accrued interest on the
     underlying Securities for distribution to the Sponsor as the Unitholder
     of record as of the First Settlement Date. A portion of the accrued
     interest ("Purchased Interest") on the underlying Securities, as
     indicated under "Summary of Essential Financial Information", is payable
     by investors and is included in the Public Offering Price. Purchased
     Interest is the difference between Accrued interest to the First
     Settlement Date and Accrued interest payable to Sponsor.

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.

*Combined State and Federal tax bracket was computed giving no effect to the
North Carolina tax on intangible personal property. Units in the Trust are not
subject to such tax; therefore, equivalent taxable estimated current returns
would be greater than the equivalent taxable estimated current returns
indicated in the table when compared to obligations subject to the North
Carolina tax on intangible personal property.

     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.

2.   Noncancellability and Termination-Refunds of Premium
     
     This Policy cannot be cancelled by AMBAC.  The insurance provided by
this Policy shall remain in force throughout the Policy period.  This
Policy provides for payment to the Trustee as a result of Nonpayment of
the Bonds.  In the event the Trustee sells any of the Bonds, then this
Policy shall be terminated as to any such Bond on the date of said sale,
and AMBAC shall not have any liability under t his Policy on account of
Nonpayment of any such Bond occurring thereafter.  This Policy shall be
terminated as to any Bond which AMBAC has been notified by the Sponsor or

was not deposited by the Sponsor, or the contract to purchase which has
failed, on the date such notice is received by AMBAC, and AMBAC shall not
have any liability under this Policy on account of Nonpayment of any such
Bond occurring thereafter.  When AMBAC is notified by the Trustee or the
Sponsor that any of the Bonds have been redeemed or sold from the
Investment Trust, or were not deposited into it, or a contract to
purchase any such Bonds has failed, a refund of any prepaid premium
thereof shall be made to the Investment Trust or the Sponsor, as the case
may be.  Such notification to AMBAC must specify the amount of Bonds
affected, identify each by its Item Number in an Application identified
by its date and designate the date of such disposal or failure.


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

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

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

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


4.   Rights of AMBAC

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

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

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

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


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


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


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


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


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

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

Gentlemen:

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

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

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

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

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

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

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

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

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

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

     11.   Default by Other Underwriters.  Default by any one or more  of
the other Underwriters in respect of their several obligations under this

           2.    The  certificates evidencing the Units  in  the  several
     Trusts of the Fund when duly executed and delivered by the Depositor
     and   the  Trustee  in  accordance  with  the  aforementioned  Trust

     Re: Insured Municipals Income Trust and Investors' Quality
                   Tax-Exempt Trust, Multi-Series 221
             ______________________________________________

Gentlemen:
     
     We  have acted as counsel for Van Kampen Merritt Inc., Depositor  of
Insured Municipals Income Trust and Investors' Quality Tax-Exempt  Trust,
Multi-Series 221 (the "Fund"), in connection with the issuance  of  Units
of fractional undivided interest in the several Trusts of said Fund under
a Trust Agreement dated May 19, 1994 (the "Indenture") between Van Kampen
Merritt  Inc.,  as Depositor, American Portfolio Evaluation  Services,  a
division  of Van Kampen Merritt Investment Advisory Corp., as  Evaluator,
and The Bank of New York, as Trustee.
     
     In this connection, we have examined the Registration Statement, the
form  of Prospectus proposed to be filed with the Securities and Exchange
Commission, the Indenture and such other instruments and documents as  we
have deemed pertinent.
     
     Based  upon the foregoing and upon an investigation of such  matters
of law as we consider to be applicable, we are of the opinion that, under
existing Federal income tax law:
     
          (i)   Each Trust is not an association taxable as a corporation
     but will be governed by the provisions of subchapter J (relating  to
     trusts) of chapter 1, Internal Revenue Code of 1986 (the "Code").
     
         (ii)    Each Unitholder will be considered as owning a pro  rata
     share  of each asset of the respective Trust in the proportion  that
     the  number  of Units of such Trust held by him bears to  the  total
     number  of  Units  outstanding  of such  Trust.   Under  subpart  E,
     subchapter J of chapter 1 of the Code, income of each Trust will  be
     treated as income of each Unitholder of the respective Trust in  the
     proportion described, and an item of Trust income will have the same
     character in the hands of a Unitholder as it would have in the hands
     of  the  Trustee.  Accordingly, to the extent that the income  of  a
     Trust  consists  of  interest excludable  from  gross  income  under
     Section 103 of the Code, such income will be excludable from Federal
     gross  income of the Unitholders, except in the case of a Unitholder
     who  is a substantial user (or a person related to such user)  of  a
     facility  financed  through issuance of any  industrial  development
     bonds  or  certain  private activity bonds held  by  the  respective
     Trust.   In  the  case  of such Unitholder (and no  other)  interest
     received  with respect to his Units attributable to such  industrial
     development  bonds or such private activity bonds is  includable  in
     his gross income.  In the case of certain corporations, interest  on
     the  Bonds  is  included  in computing the alternative  minimum  tax
     pursuant  to Section 56(c) of the Code, the environmental  tax  (the
     "Superfund Tax") imposed by Section 59A of the Code, and the  branch
     profits tax imposed by Section 884 of the Code with respect to  U.S.
     branches of foreign corporations.
     
        (iii)    Gain  or  loss will be recognized to a  Unitholder  upon
     redemption  or sale of his Units.  Such gain or loss is measured  by
     comparing the proceeds of such redemption or sale with the  adjusted
     basis   of  the  Units  represented  by  his  Certificate.    Before
     adjustment, such basis would normally be cost if the Unitholder  had
     acquired  his Units by purchase, plus his aliquot share of  advances
     by the Trustee to the Trust to pay interest on Bonds delivered after
     the  Unitholder's settlement date to the extent that  such  interest
     accrued  on  the  Bonds  during  the period  from  the  Unitholder's
     settlement  date  to  the  date such  Bonds  are  delivered  to  the
     respective Trust, but only to the extent that such advances  are  to
     be repaid to the Trustee out of interest received by such Trust with
     respect to such Bonds.  In addition, such basis will be increased by
     the  Unitholder's  aliquot  share  of  the  accrued  original  issue
     discount with respect to each Bond held by the Trust with respect to
     which there was an original issue discount at the time the Bond  was
     issued  and  reduced by the annual amortization of bond premium,  if
     any, on Bonds held by the Trust.
     
        (iv)   If the Trustee disposes of a Trust asset (whether by sale,
     payment  on  maturity,  redemption or otherwise)  gain  or  loss  is
     recognized  to the Unitholder and the amount thereof is measured  by
     comparing the Unitholder's aliquot share of the total proceeds  from
     the  transaction with his basis for his fractional interest  in  the
     asset  disposed  of.  Such basis is ascertained by apportioning  the
     tax  basis for his Units among each of the Trust assets (as  of  the
     date  on  which his Units were acquired) ratably according to  their
     values  as  of  the  valuation date nearest the  date  on  which  he
     purchased such Units.  A Unitholder's basis in his Units and of  his
     fractional  interest  in each Trust asset must  be  reduced  by  the
     amount  of  his aliquot share of interest received by the Trust,  if
     any,  on  Bonds delivered after the Unitholder's settlement date  to
     the extent that such interest accrued on the Bonds during the period
     from  the  Unitholder's settlement date to the date such  Bonds  are
     delivered  to  the Trust, must be reduced by the annual amortization
     of  bond  premium, if any, on Bonds held by the Trust  and  must  be
     increased  by  the Unitholder's share of the accrued original  issue
     discount  with respect to each Bond which, at the time the Bond  was
     issued, had original issue discount.
     
          (v)    In  the  case of any Bond held by the  Trust  where  the
     "stated  redemption  price at maturity" exceeds the  "issue  price",
     such  excess shall be original issue discount.  With respect to each
     Unitholder,  upon  the  purchase of  his  Units  subsequent  to  the
     original issuance of Bonds held by the Trust, Section 1272(a)(7)  of
     the Code provides for a reduction in the accrued "daily portion"  of
     such  original issue discount upon the purchase of a Bond subsequent
     to  the Bond's original issue, under certain circumstances.  In  the
     case  of  any  Bond  held  by the Trust the  interest  on  which  is
     excludable  from  gross income under Section 103 of  the  Code,  any
     original issue discount which accrues with respect thereto  will  be
     treated  as  interest which is excludable from  gross  income  under
     Section 103 of the Code.
     
         (vi)   We have examined the Municipal Bond Unit Investment Trust
     Insurance policies, if any, issued to certain of the Trusts  on  the
     Date  of  Deposit by AMBAC Indemnity Corporation, Financial Guaranty
     Insurance  Corporation or a combination thereof.  Each such  policy,
     or  a  combination of such policies, insures all bonds held  by  the
     Trustee  for  that particular Trust (other than bonds  described  in
     paragraph  (vii)) against default in the prompt payment of principal
     and  interest.   In  our opinion, any amount paid  under  each  said
     policy, or a combination of said policies, which represents maturing
     interest  on  defaulted  obligations held by  the  Trustee  will  be
     excludable from federal gross income if, and to the same extent  as,
     such  interest would have been so excludable if paid by the  issuer.
     Paragraph  (ii)  of  this  opinion  is  accordingly  applicable   to
     insurance proceeds representing maturing interest.
     
        (vii)   Certain bonds in the portfolios of certain of the Insured
     Trusts  have been insured by the issuers thereof against default  in
     the  prompt payment of principal and interest.  Insurance  has  been
     obtained for such bonds, or, in the case of a commitment, the  bonds
     will  be  ultimately insured under the terms of  such  an  insurance
     policy,  which  are  designated  as  issuer  insured  bonds  on  the
     portfolio pages of the respective Trusts in the prospectus  for  the
     Fund, by the issuer of such bonds.  Insurance obtained by the issuer
     is  effective so long as such bonds remain outstanding.  For each of
     these  bonds,  we  have  been advised that the  aggregate  principal
     amount of such bonds listed on the portfolio page for the respective
     Trust  was  acquired by the applicable Trust and  are  part  of  the
     series of such bonds listed on the portfolio page for the respective
     Trust in the aggregate principal amount listed on the portfolio page
     for  the respective Trust.  Based upon the assumption that the bonds
     acquired  by the applicable Trust are part of the series covered  by
     an  insurance  policy  or,  in the case of  a  commitment,  will  be
     ultimately  insured under the terms of such an insurance policy,  it
     is  our  opinion  that any amounts received by the applicable  Trust
     representing maturing interest on such bonds will be excludable from
     federal  gross  income if, and to the same extent as, such  interest
     would have been so excludable if paid in normal course by the Issuer
     notwithstanding  the source of the payment is from policy  proceeds.
     Paragraph  (ii)  of this opinion is accordingly applicable  to  such
     payment.
     
     Sections  1288 and 1272 of the Code provide a complex set  of  rules
governing  the  accrual of original issue discount.  These rules  provide
that  original issue discount accrues either on the basis of  a  constant
compound interest rate or ratably over the term of the Bond, depending on
the  date the Bond was issued.  In addition, special rules apply  if  the
purchase price of a Bond exceeds the original issue price plus the amount
of original issue discount which 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.
     
     Because  the  Trusts  do  not include any "private  activity"  bonds
within  the meaning of Section 141 of the Code issued on or after  August
15, 1986, none of the Trust Fund's interest income shall be treated as an
item  of  tax preference when computing the alternative minimum tax.   In
the  case of corporations, for taxable years beginning after December 31,
1986,  the alternative minimum tax and the Superfund Tax depend upon  the
corporation's taxable income with certain adjustments.
     
     Pursuant  to Section 56(c) of the Code, one of the adjustment  items
used  in  computing alternative minimum taxable income ("AMTI")  and  the
Superfund  Tax  of a corporation (other than an S corporation,  Regulated
Investment  Company, Real Estate Investment Trust or REMIC)  for  taxable
years  beginning after 1989, is an amount equal to 75% of the  excess  of
such  corporation's "adjusted current earnings" over an amount  equal  to
its  AMTI  (before  such  adjustment item and  the  alternative  tax  net
operating loss deduction).  "Adjusted current earnings" includes, all tax-
exempt  interest, including interest on all Bonds in the Trust, and  tax-
exempt original issue discount.
     
     Effective  for  tax  returns  filed after  December  31,  1987,  all
taxpayers  are required to disclose to the Internal Revenue  Service  the
amount of tax-exempt interest earned during the year.
     
     Section  265  of the Code provides for a reduction in  each  taxable
year  of 100 percent of the otherwise deductible interest on indebtedness
incurred or continued by financial institutions, to which either  Section
585  or Section 593 of the Code applies, to purchase or carry obligations
acquired  after  August 7, 1986, the interest on  which  is  exempt  from
Federal  income taxes for such taxable year.  Under rules  prescribed  by
Section  265,  the  amount  of  interest  otherwise  deductible  by  such
financial  institutions  in  any taxable  year  which  is  deemed  to  be
attributable  to  tax-exempt obligations acquired after August  7,  1986,
will  be  the amount that bears the same ratio to the interest  deduction
otherwise  allowable (determined without regard to Section  265)  to  the
taxpayer  for  the taxable year as the taxpayer's average adjusted  basis
(within  the meaning of Section 1016) of tax-exempt obligations  acquired
after August 7, 1986, bears to such average adjusted basis for all assets
of   the  taxpayer,  unless  such  financial  institution  can  otherwise
establish,  under regulations, to be prescribed by the Secretary  of  the
Treasury, the amount of interest on indebtedness incurred or continued to
purchase or carry such obligations.
     
     We  also call attention to the fact that, under Section 265  of  the
Code, interest on indebtedness incurred or continued to purchase or carry
Units  is  not deductible for Federal income tax purposes.   Under  rules
used  by the Internal Revenue Service for determining when borrowed funds
are  considered used for the purpose of purchasing or carrying particular
assets,  the purchase of Units may be considered to have been  made  with
borrowed  funds even though the borrowed funds are not directly traceable
to the purchase of Units.  However, these rules generally do not apply to
interest  paid  on indebtedness incurred for expenditures of  a  personal
nature  such  as  a mortgage incurred to purchase or improve  a  personal
residence.
     
     "The  Revenue  Reconciliation  Act of  1993"  (the  "Tax  Act") 
subjects tax-exempt bonds to  the  market discount rules of the Code
effective for bonds purchased after April  30, 1993.   In  general,
market discount is the amount (if any) by which  the stated redemption
price at maturity exceeds an investor's purchase  price (except  to  the
extent that such difference, if any, is attributable  to original  issue 
discount not yet accrued).  Market  discount  can  arise based on the
price a Trust pays for Bonds or the price a Unitholder  pays for his or
her Units.  Under the Tax Act, accretion of market discount is taxable
as  ordinary  income; under prior law, the  accretion  had  been treated 
as  capital gain.  Market discount that accretes while  a  Trust holds
a  Bond would be recognized as ordinary income by the  Unitholders when 
principal  payments  are received on the  Bond,  upon  sale  or  at
redemption  (including early redemption), or upon the sale or  redemption
of  his  or  her  Units,  unless a Unitholder elects  to  include  market
discount in taxable income as it accrues.
     
     We  have also examined  certain laws of the State of New Mexico,  to
determine  their applicability to the New Mexico Trust (the  "New  Mexico
Trust")  being created as a part of the Fund and to the holders of  Units
of  the  New  Mexico Trust who are residents of the State of  New  Mexico
("New Mexico Unitholders").
     
     The  assets of the New Mexico Trust will consist of interest-bearing
obligations  issued  by or on behalf of the State  of  New  Mexico  ("New
Mexico")   or   counties,   municipalities,  authorities   or   political
subdivisions  thereof (the "New Mexico Bonds") or by the Commonwealth  of
Puerto  Rico, Guam and the United States Virgin Islands (the  "Possession
Bonds") (collectively, the "Bonds").
     
     Although we express no opinion with respect to the issuance  of  the
Bonds,  in rendering our opinion expressed herein, we have assumed  that:
(i)  the  Bonds  were  validly  issued,  (ii)  the  interest  thereon  is
excludable  from gross income for federal income tax purposes  and  (iii)
the  interest thereon is exempt from taxation for purposes of the  income
tax imposed on individuals and the income tax imposed on corporations  by
New  Mexico  (collectively, the "New Mexico  State  Income  Tax").   This
opinion  does  not address the taxation of persons other than  full  time
residents of New Mexico.
     
     Based  on  the  foregoing, and based on review and consideration  of
existing  laws of New Mexico as of this date, it is our opinion,  and  we
herewith advise you, as follows:
     
          (1)   The New Mexico Trust will not be subject to tax under the
     New Mexico State Income Tax.
     
          (2)    Income on the Bonds which is exempt from the New  Mexico
     State  Income Tax when received by the New Mexico Trust,  and  which
     would  be  exempt from the New Mexico State Income Tax  if  received
     directly  by  a  New Mexico Unitholder, will retain  its  status  as
     exempt  from  such  tax when received by the New  Mexico  Trust  and
     distributed  to  such New Mexico Unitholder provided  that  the  New
     Mexico  Trust complies with the reporting requirements contained  in
     the New Mexico State Income Tax Regulations.
     
          (3)   To the extent that interest income, derived from the  New
     Mexico  Trust  by a Unitholder with respect to Possession  Bonds  is
     excludable  from  gross  income  for  Federal  income  tax  purposes
     pursuant  to  48 U.S.C. 745, 48 U.S.C. 1423a, or 48 U.S.C.  1403,
     such  interest income, will not be subject to the New  Mexico  State
     Income Tax.
     
         (4)   Each New Mexico Unitholder will recognize gain or loss for
     New  Mexico State Income Tax purposes if the Trustee disposes  of  a
     bond (whether by redemption, sale or otherwise) or if the New Mexico
     Unitholder  redeems or sells Units of the New Mexico  Trust  to  the
     extent that such a transaction results in a recognized gain or  loss
     to such New Mexico Unitholder for federal income tax purposes.
     
          (5)    Although no opinion is expressed herein,  we  have  been
     informally advised by the Tax Information Division of the New Mexico
     Department  of  Revenue  that  any  insurance  proceeds  paid  under
     policies  which represent maturing interest on defaulted obligations
     which  are  excludable  from gross income  for  federal  income  tax
     purposes  should be excludable form the New Mexico State Income  Tax
     to  the same extent as such interest would have been if paid by  the
     issuer of such Bonds held by the New Mexico Trust.
     
          (6)    The  New  Mexico  State Income Tax  does  not  permit  a
     deduction  of  interest  paid  on  indebtedness  or  other  expenses
     incurred  (or continued) in connection with the purchase or carrying
     of  Units in the New Mexico Trust to the extent that interest income
     related  to  the  ownership of Units is exempt from the  New  Mexico
     income tax.
     
     We  have  not examined any of the Bonds to be deposited and held  in
the  New Mexico Trust or the proceedings for the issuance thereof or  the
opinions  of bond counsel with respect thereto, and therefore express  no
opinion  as to the exemption from federal income taxation of interest  on
the  Bonds or from the New Mexico State Income Tax of interest or profits
on  the  Bonds if interest thereon had been received directly  by  a  New
Mexico Unitholder.
     
     We  have  also  examined certain laws of the  State  of  Oregon,  to
determine  their applicability to the Oregon Quality Trust  (the  "Oregon
Trust") being created as part of the Fund and to the holders of Units  in
the  Oregon  Trust  who  are residents of the State  of  Oregon  ("Oregon
Unitholder").  The assets of the Oregon Trust will consist  of  interest-
bearing  obligations issued by or on behalf of the State of  Oregon  (the
"State")   or   counties,   municipalities,  authorities   or   political
subdivisions  thereof ("Oregon Bonds") or by the Commonwealth  of  Puerto
Rico,  Guam and the United States Virgin Islands (the "Possession Bonds")
(collectively  the  "Bonds").  Although no opinion  is  expressed  herein
regarding  such matters, it is assumed that: (i) the Bonds  were  validly
issued,  (ii)  the interest thereon is excludible 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 Oregon  income  tax
applicable  to individual, ("Oregon Personal Income Tax").   The  opinion
set  forth below does not address the taxation of persons other than full
time residents of Oregon.
     
     Based  on  the  foregoing, and based on review and consideration  of
existing  laws  of the State as of this date, it is our  opinion  and  we
herewith advise you, as follows:
     
          (1)    The  Oregon  Trust is not an association  taxable  as  a
     corporation  and  based upon an administrative rule  of  the  Oregon
     State  Department of Revenue, each Oregon Unitholder  of  the  Trust
     will  be  essentially treated as the owner of a pro rata portion  of
     the  Oregon Trust and the income of such portion of the Oregon Trust
     will  be  treated as the income of the Oregon Unitholder for  Oregon
     Personal Income Tax purposes;
     
          (2)    interest  on the Bonds which is exempt from  the  Oregon
     Personal  Income  Tax when received by the Oregon Trust,  and  which
     would  be  exempt  from the Oregon Personal Income Tax  if  received
     directly  by an Oregon Unitholder, will retain its status as  exempt
     from  such tax when received by the Oregon Trust and distributed  to
     an Oregon Unitholder;
     
          (3)   to the extent that interest derived from the Oregon Trust
     by  an  Oregon  Unitholder with respect to the Possession  Bonds  is
     excludable  from  gross  income  for  Federal  income  tax  purposes
     pursuant  to  48 U.S.C. 745, 48 U.S.C. 1423a and 48 U.S.C.  1403,
     such interest will not be subject to the Oregon Personal Income Tax;
     
          (4)   each Oregon Unitholder of the Oregon Trust will recognize
     gain  or loss for Oregon Personal Income Tax purposes if the Trustee
     disposes of a bond (whether by redemption, sale or otherwise) or  if
     the Oregon Unitholder redeems or sells Units of the Oregon Trust  to
     the  extent that such a transaction results in a recognized gain  or
     loss to such Oregon Unitholder for Federal income tax purposes; and
     
         (5)   the Oregon Personal Income Tax does not permit a deduction
     of  interest paid or incurred on indebtedness incurred or  continued
     to  purchase  or  carry Units in the Oregon Trust, the  interest  on
     which is exempt from such Tax.
     
     We  have  not examined any of the Bonds to be deposited and held  in
the  Oregon  Trust  or the proceedings for the issuance  thereof  or  the
opinions  of bond counsel with respect thereto, and therefore express  no
opinion  as  to  the  exemption from the Oregon Personal  Income  Tax  of
interest on the Bonds if received directly by a Unitholder.  In addition,

  prospective  purchasers  subject to the  Oregon  corporate  income  tax
should  be  advised  that  for purposes of the  Oregon  Corporate  Income
(Excise)  Tax, interest on the Oregon Bonds received by the Oregon  Trust
and distributed to an Oregon Unitholder subject to such tax will be added
to the corporate Oregon Unitholder's federal taxable income and therefore
will be taxable.

                                    Very truly yours,

                                    Chapman and Cutler

Insured Municipals Income Trust and
Investors' Quality Tax-Exempt Trust,
Multi-Series 221
c/o The Bank of New York,
As Trustee
101 Barclay Street, 17 West
New York, New York 10286

Dear Sirs:
     
     We  have acted as special counsel for the Insured Municipals  Income
Trust  and  Investors'  Quality Tax-Exempt Trust, Multi-Series  221  (the
"Fund")  consisting  of  Insured Municipals  Income  Trust,  Series  325,
Insured  Municipals  Income Trust, 78th Intermediate Series,  New  Mexico
Insured   Municipals  Income  Trust,  Series  14,  Pennsylvania   Insured
Municipals  Income  Trust, Series 187, Kentucky Investors'  Quality  Tax-
Exempt  Trust,  Series  51,  North Carolina Investors'  QualityTax-Exempt
Trust,  Series 75 and Oregon Investors' Quality Tax-Exempt Trust,  Series
52  (in  the  aggregate the "Trusts" and individually "Trusts")  for  the
purpose of determining the applicability of certain New York taxes  under
the circumstances hereinafter described.
     
        The   Fund  is  created  pursuant  to  a  Trust  Agreement   (the
"Indenture"), dated as of today (the "Date of Deposit") among Van  Kampen
Merritt Inc. (the "Depositor"), American Portfolio Evaluation Services, a
division  of Van Kampen Merritt Investment Advisory Corp., as  Evaluator,
and The Bank of New York as Trustee (the "Trustee").  As described in the
prospectus  relating to the Fund dated today to be filed as an  amendment
to  a  registration  statement previously filed with the  Securities  and
Exchange  Commission (file number 33-53251) under the Securities  Act  of
1933,  as amended (the "Prospectus"), the objectives of the Fund are  the
generation  of  income exempt from Federal taxation and as  regards  each
Trust  denominated with the name of a state exempt from  income  tax,  if
any, of the denominated in the name of that Trust to the extent indicated
in  the  Prospectus.  No opinion is expressed herein with regard  to  the
Federal  or  State tax aspects of the bonds, the Fund, and units  of  the
Trust (the "Units"), or any interest, gains or losses in respect thereof.
     
     As  more fully set forth in the Indenture and in the Prospectus, the
activities of the Trustee will include the following:
     
     On  the Date of Deposit, the Depositor will deposit with the Trustee
with  respect  to  each Trusts, the total principal  amount  of  interest
bearing  obligations and/or contracts for the purchase  thereof  together
with  an  irrevocable  letter of credit in the amount  required  for  the
purchase  price and accrued interest, if any, and, in the case of  Trusts
denominated as "Insured," an insurance policy purchased by the  Depositor
evidencing the insurance guaranteeing the timely payment of principal and
interest  of  the obligations comprising the corpus of that  Trust  other
than  those  obligations the timely payment of principal and interest  of
which  are  guaranteed  by an insurance policy purchased  by  the  issuer
thereof  or a prior owner, which may include the Depositor prior  to  the
Date  of  Deposit, as more fully set forth in the Prospectus with respect
to each Trust.
     
     We  understand  with  respect to the obligations  described  in  the
preceding  paragraph  that  all  insurance,  whether  purchased  by   the
Depositor,  the issuer or a prior owner, provides, or will provide,  that
the  amount paid by the insurer in respect of any bond may not exceed the
amount of principal and interest due on the bond and such payment will in
no  event  relieve the issuer from its continuing obligation to pay  such
defaulted  principal and interest in accordance with  the  terms  of  the
obligation.
     
     The Trustee will not participate in the selection of the obligations
to  be deposited in the Fund, and, upon the receipt thereof, will deliver
to  the  Depositor  a  registered certificate for  the  number  of  Units
representing the entire capital of each of the Trusts as more  fully  set
forth in the Prospectus and the Registration Statement.  The Units, which
are  represented by certificates ("Certificates"), will be offered to the
public  by  the  Prospectus upon the effectiveness  of  the  Registration
Statement.
     
     The  duties  of the Trustee, which are ministerial in  nature,  will
consist  primarily  of crediting the appropriate accounts  with  interest
received by each of the Trusts and with the proceeds from the disposition
of  obligations held in each of the Trusts and the distribution  of  such
interest  and  proceeds to the Unit holders of that Trust.   The  Trustee
will  also  maintain  records of the registered holders  of  Certificates
representing  an interest in each Trust and administer the redemption  of
Units  by such Certificate holders and may perform certain administrative
functions with respect to an automatic investment option.
     
     Generally, obligations held in the Fund may be removed therefrom  by
the  Trustee only upon redemption prior to their stated maturity, at  the
direction of the Depositor in the event of an advance refunding, or  upon
the  occurrence of certain other specified events which adversely  affect
the sound investment character of the Fund, such as default by the issuer
in  payment  of interest or principal on the obligation and no  provision
for  payment is made therefor either pursuant to the portfolio  insurance
or  otherwise  and  the Depositor fails to instruct the  Trustee,  within
thirty (30) days after notification, to hold such obligation.
     
     Prior  to  the termination of the Fund, the Trustee is empowered  to
sell  Bonds, from a list furnished by the Evaluator, only for the purpose
of  redeeming Units tendered to it and of paying expenses for which funds
are  not  available.  The Trustee does not have the  power  to  vary  the
investment of any Unit holder in the Fund, and under no circumstances may
the  proceeds  of  sale of any obligations held by the Fund  be  used  to
purchase new obligations to be held therein.
     
     Article  9-A  of  the New York Tax Law imposes a  franchise  tax  on
business corporations, and, for purposes of that Article, Section  208(l)
defines  the  term  "corporation" to include, among  other  things,  "any
business conducted by a trustee or trustees wherein interest or ownership
is evidenced by certificate or other written instrument."
     
     The Regulations promulgated under Section 208 provide as follows:
          
          The  term  "trust"  includes  any  business  business
          conducted by a trustee or trustees in which  interest
          or  ownership  is evidenced by certificate  or  other
          written  instrument.  Such a trust includes,  but  is
          not  limited to, an association commonly referred  to
          as  a "business trust" or "Massachusetts trust."   In
          determining   whether  a  trustee  or  trustees   are
          conducting  a business, the form of the agreement  is
          of  significance but is not controlling.  The  actual
          activities  of  the  trustee or trustees,  not  their
          purposes  and  powers, will be regarded  as  decisive
          factors in determining whether a trust is subject  to
          tax  under Article 9-A.  The mere investment of funds
          and   the   collection  of  income  therefrom,   with
          incidental replacement of securities and reinvestment
          of  funds,  does  not constitute  the  conduct  of  a
          business in the case of a business conducted  by  the
          trustee  or trustees. 20 NYCRR 1-2.3(b)(2) (July  11,
          1990).
     
     New York cases dealing with the question of whether a trust will  be
subject  to the franchise tax have also delineated the general rule  that
where  a  trustee  merely invests funds and collects and distributes  the
income therefrom, the trust is not engaged in business and is not subject
to  the  franchise tax.  Burrell v. Lynch, 274 A.D. 347, 84 N.Y.S.2d  171
(3rd Dept. 1948), order resettled, 274 A.D. 1073, 85 N.Y.S.2d 705 (1949).
     
     An opinion of the Attorney General of the State of New York, 47 N.Y.
Atty.  Gen. Rep. 213 (Nov. 24, 1942), it was held that where the  trustee
of  an  unincorporated investment trust was without authority to reinvest
amounts  received  upon  the sales of securities  and  could  dispose  of
securities  making  up  the  trust only upon  the  happening  of  certain
specified  events or the existence of certain specified  conditions,  the
trust was not subject to the franchise tax.
     
     In  the  instant  situation, the Trustee is not  empowered  to  sell
obligations contained in the corpus of the Fund and reinvest the proceeds
therefrom.   Further, the power to sell such obligations  is  limited  to
circumstances  in  which  the  creditworthiness  or  soundness   of   the
obligation  is  in question or in which cash is needed to  pay  redeeming
Unit holders or to pay expenses, or where the Fund is liquidated pursuant
to  the termination of the Indenture.  Only in circumstances in which the
issuer of an obligation attempts to refinance it can the Trustee exchange
an  obligation for a new security.  In substance, the Trustee will merely
collect  and  distribute  income and will  not  reinvest  any  income  or
proceeds, and the Trustee has no power to vary the investment of any Unit
holder in a Trust.
     
     Under Subpart E of Part I, Subchapter J of Chapter 1 of the Internal
Revenue  Code of 1986, as amended (the "Code"), the grantor  of  a  trust
will  be deemed to be the owner of the trust under certain circumstances,
and  therefore  taxable  on  his proportionate  interest  in  the  income
thereof.   Where this Federal tax rule applies, the income attributed  to
the  grantor will also be income to him for New York income tax purposes.
See  TSB-M-78(9)(c), New York Department of Taxation and Finance June 23,
1978.
     
     Article  22 (Personal Income Tax) of the New York Tax Law imposes  a
tax  on  a  New  York  State resident individual's State  adjusted  gross
income.   Such  amount is defined by Section 612 as his Federal  adjusted
gross income, with an addition for interest income on the obligations  of
a  State  or  political subdivision of a state other than  New  York,  is
excluded from his federal adjusted gross income.  Such amount is  defined
by  Section T46-112 of the Administrative Code of the City of New York as
his  Federal adjusted gross income, with an addition for interest  income
on  the obligations of a state or political subdivision of a state  other
than  New  York,  if  excluded from his federal  adjusted  gross  income.
48 U.S.C. Section 745 exempts interest on a bond issued by the Government
of  Puerto Rico or a political subdivision thereof from tax of the United
States,  of  any  State,  and  of any state's  county,  municipality,  or
municipal subdivision thereof.  48 U.S.C. Section 1423a exempts  interest
on  a  bond  issued  by the Government of Guam or by its  authority  from
taxation  by the United States, any state or political subdivision.   The
New  York  Trust  holds only obligations issued by New York  State  or  a
political  subdivision thereof or by the Government of Puerto Rico  or  a
political  subdivision thereof, or by the Government or Guam  or  by  its
authority.
     
     By  letter, dated today, Messrs. Chapman and Cutler, counsel for the
Depositor,  rendered their opinion that each Unit holder of a Trust  will
be  considered  as  owning a share of each asset of  that  Trust  in  the
proportion  that  the number of Units held by such holder  bears  to  the
total  number  of  Units outstanding and the income of a  Trust  will  be
treated  as  the  income  of  each Unit holder  of  that  Trust  in  said
proportion pursuant to Subpart E of Part E, subchapter J of Chapter 1  of
the Code.
     
     Based  on  the foregoing and on the opinion of Messrs.  Chapman  and
Cutler,   counsel  for  the  Depositor,  dated  today,  upon   which   we
specifically  rely,  we  are  of the opinion that  under  existing  laws,
rulings  and court decisions interpreting the laws of the State and  City
of New York.

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

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

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

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

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

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

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

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

           Tax-Exempt Trust, Pennsylvania Insured Municipals
                        Income Trust, Series 187

Gentlemen:
     
     We  are  acting as special counsel with respect to Pennsylvania  tax
matters  for  the Insured Municipals Income Trust and Investors'  Quality
Tax-Exempt  Trust Multi-State Series 221, Pennsylvania Insured Municipals
Income Trust, Series 187 (the "Fund") in connection with the issuance  of
Units  of  fractional  undivided interests in the  Fund,  under  a  Trust
Indenture  and  Agreement dated May 19, 1994 between Van Kampen  Merritt,
Inc.  ("Van  Kampen") as Depositor, American Portfolio Advisory  Service,
Inc.,  as  Evaluator, and The Bank of New York through  its  Wall  Street
Trust  division,  as  Trustee.   It is our understanding  that  the  Fund
consists  of a portfolio composed of interest-bearing obligations  issued
by  the  Commonwealth  of  Pennsylvania or by  municipalities  and  other
governmental  authorities within the Commonwealth  of  Pennsylvania  (the
"Bonds").
     
     We have not examined any preliminary or final official statements of
issuers  of  the  Bonds,  nor have we examined  any  legal  opinions,  or
summaries of such opinions, relating to the validity of the Bonds in  the
Fund,  the  exemption of interest thereon from federal  income  tax,  the
exemption  of the Bonds from personal property taxes in Pennsylvania,  or
the  exemption of the interest on and any gain from the sale of the Bonds
from  the Pennsylvania personal income tax, given or to be given by  bond
counsel  to  the issuer at the time such Bonds are issued.   Further,  we
have  made no review of the proceedings relating to the issuance  of  the
Bonds or of the basis for such opinions.  Our opinion expressed below  is
based  in  part  on  the  assurance of Van Kampen that  the  Bonds  being
deposited  in  the  Fund  have been issued only by  the  Commonwealth  of
Pennsylvania  or by or on behalf of municipalities or other  governmental
agencies within the Commonwealth of Pennsylvania.
     
     We have examined certified copies, or copies otherwise identified to
our satisfaction, of such other documents as we have deemed necessary  or
appropriate  for  the purpose of rendering this opinion, including  those
related to previous transactions in which Van Kampen Merritt Inc. was the
Depositor  which  we  have been assured by Van Kampen  Merritt  Inc.  are
substantially the same as those relating to the Fund.
     
     Based upon the foregoing, we are of the opinion that:
     
          (1)    Units evidencing fractional undivided interests  in  the
     Fund,  to  the  extent  represented by  obligations  issued  by  the
     Commonwealth  of  Pennsylvania,  any public  authority,  commission,
     board  or  other agency created by the Commonwealth of Pennsylvania,
     any political subdivision of the Commonwealth of Pennsylvania or any
     public authority created by any such political subdivision, are  not
     taxable under any of the personal property taxes presently in effect
     in Pennsylvania;
     
         (2)   Distributions of interest income to Unitholders that would
     not  be taxable if received directly by a Pennsylvania resident  are
     not subject to personal income tax under the Pennsylvania Tax Reform
     Code  of  1971; nor will such interest be taxable under Philadelphia
     School  District  Investment  Income  Tax  imposed  on  Philadelphia
     resident individuals;
     
           (3)    A  Unitholder  may  have  a  taxable  event  under  the
     Pennsylvania state and local income tax referred to in the preceding
     paragraph upon the redemption or sale of his Units;
     
          (4)    Units are subject to Pennsylvania inheritance and estate
     taxes;
     
          (5)    A  Unitholder which is a corporation may have a  taxable
     event  under  the  Pennsylvania Corporate Net Income  Tax  upon  the
     redemption  or  sale of its Units.  Interest income  distributed  to
     Unitholders  which are corporations is not subject  to  Pennsylvania
     Corporate  Net  Income  Tax  or  Mutual  Thrift  Institutions   Tax.
     However, banks, title insurance companies and trust companies may be
     required to take the value of Units into account in determining  the
     taxable value of their shares subject to Shares Tax;
     
         (6)   Under Act No. 68 of December 3, 1993, gains derived by the
     Fund  from the sale, exchange or other disposition of Bonds  may  be
     subject  to Pennsylvania personal or corporate income taxes.   Those
     gains  which  are  distributed by the Fund to  Unitholders  who  are
     individual will be subject to Pennsylvania Personal Income Tax  and,
     for  residents  of  Philadelphia, to  Philadelphia  School  District
     Investment Income Tax.  For Unitholders which are corporations,  the
     distributed  gains will be subject to Corporate Net  Income  Tax  or
     Mutual Thrift Institutions Tax.  Gains which are not distributed  by
     the  Fund will nevertheless be taxable to Unitholders if derived  by
     the  Fund  from  the  sale, exchange or other disposition  of  Bonds
     issued  on  or  after  February  1,  1994.   Gains  which  are   not
     distributed  by  the Fund will remain nontaxable to  Unitholders  if
     derived by the Fund from the sale, exchange or other disposition  of
     Bonds issued prior to February 1, 1994.  However, for gains from the
     sale,  exchange or other disposition of these Bonds  to  be  taxable
     under  the Philadelphia School District Investment Income  Tax,  the
     Bonds must be held for six months or less;
     
          (7)   Any proceeds paid under insurance policies issued to  the
     Trustee or obtained by issuers or the underwriters of the Bonds, the
     Sponsor  or others which represent interest on defaulted obligations
     held  by  the  Trustee  will be excludable from  Pennsylvania  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; and
     
           (8)     The  Fund  is  not  taxable  as  a  corporation  under
     Pennsylvania tax laws applicable to corporations.
     
     On  December 3, 1993, change to Pennsylvania law affecting  taxation
of  income  and  gains from the sale of Commonwealth of Pennsylvania  and
local  obligations were enacted.  Among these changes was the  repeal  of
the  exemption  from  tax  of  gains realized  upon  the  sale  or  other
disposition of such obligations.  The Pennsylvania Department of  Revenue
has  not  issued  any  regulations  or other  guidance  concerning  these
changes.  The opinions expressed above are based on our analysis  of  the
law  but are subject to modification upon review of regulations or  other
guidance that may be issued by the Department of Revenue.
     
     We hereby consent to the filing of this opinion as an exhibit to the

     Re:Kentucky Investors' Quality Tax-Exempt Trust, Series 51
            _______________________________________________

Gentlemen:
     
     We  have acted as special Kentucky counsel to the Insured Municipals
Income  Trust  and Investors' Quality Tax-Exempt Trust, Multi-Series  221
(the  "Fund") with respect to certain applications of the income tax  law
of  the Commonwealth of Kentucky to the Kentucky Investors' Quality  Tax-
Exempt  Trust, Series 51 (the "Kentucky Trust") being created as part  of
the  Fund  and to the holders of units of fractional undivided  interests
("Units") in the Kentucky Trust who are residents of the Commonwealth  of
Kentucky ("Kentucky Unitholders").
     
     In  this connection, we have examined relevant portions of the  form
of  Trust Agreement among Van Kampen Merritt Inc., as Depositor, American
Portfolio   Evaluation  Services,  a  division  of  Van  Kampen   Merritt
Investment Advisory Corp., as Evaluator, and The Bank of New York through
its  Wall Street Trust Division, as Trustee, to be dated the date hereof,
relating to the Units of the Kentucky Trust and the form of an opinion of
Chapman  and Cutler, counsel for Van Kampen Merritt Inc., the  Depositor,
to  be dated the date hereof, as to the federal tax status of the several
constituent trusts of the Fund and the holders of their respective Units,
including  the Kentucky Trust and the Kentucky Unitholders.  Chapman  and
Cutler  has advised us that its opinion, as executed and delivered,  will
be  in  all  material  respects identical to such  form.   We  have  also
examined  such pertinent materials and matters of law as we  have  deemed
necessary  in order to enable us to express the opinions hereinafter  set
forth.
     
     It  is  our understanding that the Kentucky Trust consists and  will
consist  of  obligations issued by the Commonwealth of  Kentucky  or  its
political  subdivisions and that interest on such  obligations  would  be
excludable  from gross income for federal income tax purposes  when  paid
directly  to a Kentucky Unitholder (with certain exceptions as set  forth
in  said  opinion of Chapman and Cutler).  The defined term, "Bonds,"  as
used   herein   means  only  such  obligations.   It   is   our   further
understanding, and the following opinion also assumes, that the  Kentucky
Trust will have no income other than (i) interest income on the Bonds and
(ii) gain on the disposition of the Bonds.
     
     The  Chapman  and Cutler opinion concludes in substance as  follows:
for federal income tax purposes, each State trust, including the Kentucky
Trust,  will not be an association taxable as a corporation but  will  be
governed  by  the  provisions of subchapter J  (relating  to  trusts)  of
Chapter  1 of the Internal Revenue Code of 1986 as amended (the  "Code");
each  Kentucky  Unitholder will be considered the owner  of  a  pro  rata
portion  of  the Kentucky Trust and will be subject to tax on the  income
therefrom under the provisions of subpart E of subchapter J of Chapter  1
of the Code; for federal income tax purposes, each item of Kentucky Trust
income will have the same character in the hands of a Kentucky Unitholder
as it would have in the hands of the Trustee; and, to the extent that the
income  of the Kentucky Trust consists of interest excludable from  gross
income under Section 103 of the Code, such income will be excludable from
federal gross income of the Kentucky Unitholders, except in the case of a
Kentucky  Unitholder who is a substantial user (or a  person  related  to
such  user)  of  a facility financed through issuance of  any  industrial
development  bonds  or private activity bonds by the Kentucky  Trust,  in
such  case income received being includable in the gross income  of  such
Kentucky  Unitholder.  Further, interest received by all Unitholders  may
be  subject  to a possible alternative minimum tax and other  direct  and
indirect tax consequences set forth in such opinion.
     
     Based  on the foregoing and because Kentucky income tax law is based
upon the federal law and, with your permission, in explicit reliance upon
and subject to the opinion of Chapman and Cutler referred to above, it is
our  opinion  that the application of existing Kentucky  income  tax  law
would be as follows:
     
         (1)   Each Kentucky Unitholder will be treated as the owner of a
     pro  rata  portion  of  the Kentucky Trust for Kentucky  income  tax
     purposes,  and  the income of the Kentucky Trust will  therefore  be
     treated  as  the  income of the Kentucky Unitholders under  Kentucky
     law;
     
         (2)   Interest on Bonds that would be exempt from federal income
     taxation when paid directly to a Kentucky Unitholder will be  exempt
     from  Kentucky  income taxation when: (i) received by  the  Kentucky
     Trust   and  attributed  to  such  Kentucky  Unitholder;  and   (ii)
     distributed to such Kentucky Unitholder;
     
         (3)   Each Kentucky Unitholder will realize taxable gain or loss
     when  the  Kentucky  Trust  disposes of a  Bond  (whether  by  sale,
     exchange,  redemption or payment at maturity) or when  the  Kentucky
     Unitholder  redeems  or  sells Units at a price  that  differs  from
     original   cost  as  adjusted  for  amortization  or   accrual,   as
     appropriate, of bond discount or premium and other basis adjustments
     (including  any basis reduction that may be required  to  reflect  a
     Kentucky  Unitholder's share of interest, if any, accruing on  Bonds
     during  the  interval  between the Kentucky Unitholder's  settlement
     date and the date such Bonds are delivered to the Kentucky Trust, if
     later);
     
          (4)    Tax cost reduction requirements relating to amortization
     of  bond  premium may, under some circumstances, result in  Kentucky
     Unitholders  realizing taxable gain when their  Units  are  sold  or
     redeemed for an amount equal to or less than their original cost;
     
          (5)    Units  of  the Kentucky Trust, to the  extent  the  same
     represent an ownership in obligations issued by or on behalf of  the
     Commonwealth  of Kentucky or governmental units of the  Commonwealth
     of  Kentucky,  the  interest on which is  exempt  from  federal  and
     Kentucky  income taxation will not be subject to ad valorem taxation
     by  the  Commonwealth  of  Kentucky  or  any  political  subdivision
     thereof; and
     
          (6)    If interest on indebtedness incurred or continued  by  a
     Kentucky Unitholder to purchase Units in the Kentucky Trust  is  not
     deductible  for  federal  income  tax  purposes,  it  also  will  be
     nondeductible for Kentucky income tax purposes.
     
     We  have  not  examined  any of the Bonds to  be  deposited  in  the
Kentucky Trust and express no opinion as to whether the interest  on  any
such  Bonds  would  in  fact be excludable from Kentucky  adjusted  gross
income if directly received by a Kentucky Unitholder.
     
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-53251) relating to the Units referred
to above and to the use of our name and the reference to our firm in such
Registration Statement, and in the related Prospectus, under the headings
"Kentucky Quality Trust - Tax Status" and "Legal Opinions."

     Re: Van Kampen Merritt, Inc.
         Insured Municipals Income Trust and
         Investors' Quality Tax-Exempt Trust, Multi-Series 221,
         North Carolina Investors' Quality Tax-Exempt Trust, Series 75

Gentlemen:
     
     We  are  acting  as special North Carolina counsel  to  the  Insured
Municipals  Income Trust and Investors' Quality Tax-Exempt Trust,  Multi-
Series  221 (the "Fund") on North Carolina tax matters relating to  North
Carolina  Investors'  Quality Tax-Exempt Trust,  Series  75  (the  "North
Carolina  Trust")  included  as part of the Fund.   Units  of  beneficial
interest  in  the  North  Carolina Trust (the "Units")  are  to  be  sold
pursuant to an effective registration statement on Form S-6 (Registration
No.  33-53251)  under  the  Securities Act  of  1933  (the  "Registration
Statement"), filed by Van Kampen Merritt, Inc. (the "Sponsor") on  behalf
of  the  Fund,  covering the Units and other units of  the  other  trusts
described in the Registration Statement.  The number of Units to be  sold
is stated in the Registration Statement.
     
     The  North Carolina Trust is to be established and the Units are  to
be  created pursuant to a Trust Agreement (the "Trust Agreement"),  dated
the  date hereof, among the Sponsor and The Bank of New York through  its
Wall Street Trust division, as Trustee (the "Trustee").  The portfolio of
the  North  Carolina Trust will consist of bonds issued by the  State  of
North  Carolina or municipalities, authorities or political  subdivisions
thereof (the "Bonds").
     
     We  have  examined originals, forms or certified copies,  or  copies
otherwise  identified  to our satisfaction, of the Trust  Agreement,  the
Registration  Statement  and  such other  documents  as  we  have  deemed
necessary for the purpose of this opinion.  We have also relied upon  the
form  of  opinion,  to  be dated the date hereof  and  addressed  to  the
Sponsor,  of Chapman and Cutler, counsel to the Sponsor, with respect  to
the matters of Federal income tax law set forth therein.
     
     Based upon the foregoing, we are of the opinion that, insofar as the
law of the State of North Carolina is concerned, upon the establishing of
the North Carolina Trust and the issuance of the Units thereunder:
     
           A.    The North Carolina Trust is not an "association" taxable
     as  a  corporation  under North Carolina law with  the  result  that
     income  of  the North Carolina Trust will be deemed to be income  of
     the Unit holders.
     
           B.    Interest on the Bonds that is exempt from North Carolina
     income tax when received by the North Carolina Trust will retain its
     tax-exempt status when received by the Unit holders.
     
           C.    Unit holders will realize a taxable event when the North
     Carolina  Trust  disposes  of  a Bond (whether  by  sale,  exchange,
     redemption or payment at maturity) or when a Unit holder redeems  or
     sells  his  Units  (or any of them), and taxable gains  for  Federal
     income  tax purposes may result in gains taxable as ordinary  income
     for  North Carolina income tax purposes.  However, when a  Bond  has
     been issued under an act of the North Carolina General Assembly that
     provides  that all income from such Bond, including any profit  made
     from  the sale thereof, shall be free from all taxation by the State
     of  North  Carolina, any such profit received by the North  Carolina
     Trust  will  retain its tax-exempt status in the hands of  the  Unit
     holders.
     
           D.   Unit holders must amortize their proportionate shares  of
     any  premium  on  a  Bond.  Amortization for each  taxable  year  is
     achieved  by lowering the Unit holder's basis (as adjusted)  in  his
     Units, with no deduction against gross income for the year.
     
           E.    The  Units  are exempt from the North  Carolina  tax  on
     intangible  personal  property so long as the corpus  of  the  North
     Carolina  Trust  remains  composed entirely  of  Bonds  or,  pending
     distribution, amounts received on the sale, redemption  or  maturity
     of  the  Bonds  and the Trustee periodically supplies to  the  North
     Carolina  Department of Revenue at such times  as  required  by  the
     Department  of Revenue a complete description of the North  Carolina
     Trust  and  also the name, description and value of the  obligations
     held in the corpus of the North Carolina Trust.
     
     In  rendering  the  foregoing opinion  we  have  not  passed  on  or
considered, among other things, the due authorization and delivery of the
Bonds  or the North Carolina income tax or intangibles tax status of  the
Bonds or income therefrom.
     
     We  consent  to  the  filing of this opinion as an  exhibit  to  the
Registration  Statement  and  to  the references  to  this  firm  in  the
Registration Statement under the headings "Tax Status Of The Trust Funds"
and "Legal Opinions."

                  Tax-Exempt Trust, Multi-Series 221*
                                    
     
     Pursuant to your request for a Standard & Poor's rating on the units
of  the  above-captioned  trust,  SEC  #33-53251  we  have  reviewed  the
information presented to us and have assigned a 'AAA' rating to the units
of  the trust and a 'AAA' rating to the securities contained in the trust
for  as  long  as  they  remain in the trust.   The  ratings  are  direct
reflections, of the portfolio of the trust, which will be composed solely
of  securities  covered by bond insurance policies  that  insure  against
default  in  the payment of principal and interest on the  securities  so
long  as they remain in the trust.  Since such policies have been  issued
by  one  or  more  insurance companies which have been assigned  a  'AAA'
claims  paying ability rating by S&P, S&P has assigned a 'AAA' rating  to
the  units of the trust and to the securities contained in the trust  for
as long as they remain in the trust.
     
     You have permission to use the name of Standard & Poor's Corporation
and  the above-assigned ratings in connection with your dissemination  of
information relating to these units, provided that it is understood  that
the ratings are not "market" ratings nor recommendations to buy, hold, or
sell  the  units of the trust or the securities contained in  the  trust.
Further,  it should be understood the rating on the units does  not  take
into  account the extent to which fund expenses or portfolio asset  sales
for  less than the fund's purchase price will reduce payment to the  unit
holders  of  the  interest  and principal required  to  be  paid  on  the
portfolio  assets.   S&P reserves the right to advise  its  own  clients,
subscribers,  and the public of the ratings.  S&P relies on  the  sponsor
and  its  counsel,  accountants, and other experts for the  accuracy  and
completeness of the information submitted in connection with the ratings.
S&P  does  not  independently verify the truth or accuracy  of  any  such
information.
     
     This letter evidences our consent to the use of the name of Standard
&  Poor's Corporation in connection with the rating assigned to the units
in  the registration statement or prospectus relating to the units or the
trust.  However, this letter should not be construed as a consent by  us,
within the meaning of Section 7 of the Securities Act of 1933, to the use
of  the  name  of  Standard & Poor's Corporation in connection  with  the
ratings  assigned  to the securities contained in  the  trust.   You  are
hereby  authorized to file a copy of this letter with the Securities  and
Exchange Commission.
     
     Please  be  certain to send us three copies of your final prospectus
as  soon  as it becomes available.  Should we not receive them  within  a
reasonable  time  after the closing or should they  not  conform  to  the
representations made to us, we reserve the right to withdraw the rating.
     
     We  are pleased to have had the opportunity to be of service to you.
If we can be of further help, please do not hesitate to call upon us.
