                                PROSPECTUS PART I

                   INSURED MUNICIPALS INCOME TRUST, SERIES 399



- --------------------------------------------------------------------------------





   Insured Municipals Income Trust, Series 399 (the "Trust") (included in
Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 301 (the "Fund")) consists of interest-bearing obligations issued
by or on behalf of municipalities and other governmental authorities, the
interest on which is, in the opinion of bond counsel to the issuer, exempt from
all Federal income taxes under existing law (the "Bonds"). The objective of the
Trust is Federal tax-exempt income and conservation of capital through an
investment in a diversified portfolio of tax-exempt bonds. The Units of the
Trust are rated "AAA" by Standard & Poor's. The Trust is referred to herein as
the "IM-IT Trust" or "Insured Trust". For a discussion of the Federal tax status
of income earned on Units, see "Federal Tax Status" in Prospectus Part II.

   The Trust consists of 16 issues of Bonds. Three of the Bonds 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) as follows: Health Care, 4 (34%); General Obligation, 3 (19%);
Transportation, 2 (12%); General Purpose, 1 (11%); Public Education, 2 (6%);
Higher Education, 1 (5%); Water and Sewer, 1 (5%); Wholesale Electric, 1 (4%)
and Public Building, 1 (4%). Approximately 26% of the principal amount of Bonds
are issued by issuers in Illinois. The dollar weighted average maturity of the
Bonds is 28 years.

                                              Monthly                Semi-Annual
                                         -------------            ------------
 Estimated Current Return:                     4.69%                    4.74%
 Estimated Long Term Return:                   4.73%                    4.78%
 CUSIP:                                     45809C-64-8              45809C-65-5
    

   Estimated Current Return shows the estimated cash to be received each year
from the Bonds (net of estimated annual expenses) divided by the Public Offering
Price (including the sales charge).
   Estimated Long-Term Return shows the estimated return over the estimated life
of the Trust. This is based on an average of the yields to maturity (or an
earlier call date) of the Bonds adjusted to reflect the sales charge and
estimated expenses. The average yield for the portfolio is derived by weighting
each Bond's yield by its value and the time remaining to the call or maturity
date, depending on how the Bond is priced. Unlike Estimated Current Return,
Estimated Long-Term Return accounts for maturities, discounts and premiums of
the Bonds.
   No return calculation can predict your actual return because returns vary
with purchase price, sales charges, the length of the time Units are held and
changes in portfolio composition, interest income and expenses. The estimated
returns are designed to show a comparison rather than a prediction of returns. A
yield calculation, which is more comparable to a calculation of an individual
bond, may be higher or lower than these estimated returns which are more
comparable to return calculations of other investment products.

(1) Because certain of the Bonds may from time to time under certain
    circumstances be sold or redeemed or will be called or mature in accordance
    with their terms (including the call or sale of zero coupon bonds at prices
    less than par value), there is no guarantee that the value of each Unit at
    Trust termination will be equal to the Principal Amount of Bonds per Unit.
(2) After the First Settlement Date (May 28, 1998),  Unitholders will pay 
    accrued interest from such date to the settlement date less  distributions
    from the Interest Account after the First Settlement Date.
(3) This is based on estimated cash flows per Unit which will vary with changes
    in expenses, interest rates and maturity, call, exchange or sale of the
    Bonds. Estimated cash flows are set forth in the Information Supplement or
    are available upon request.
(4) Excludes insurance expenses.
(5) This fee is assessed per $1,000 principal amount of Bonds. Other fees are
    assessed per Unit.
(6) During the first year the Trustee will reduce its fee by approximately $.18
    per Unit (which is the estimated interest to be earned prior to the expected
    delivery dates for the "when, as and if issued" Bonds). Should the interest
    exceed this amount, the Trustee will reduce its fee up to its annual fee.
    After the first year, the Trustee's fee will be the amount indicated above.
    Estimated interest income will increase to $49.05. Estimated Expenses will
    increase to $2.13 and $1.65 under the monthly and semi-annual distribution
    plans, respectively. Estimated Net Interest Income will remain as shown.

All of the Bonds are insured either by one of the Preinsured Bond Insurers as
indicated in the Bond name or by a Portfolio Insurer under a portfolio insurance
policy. See "Insurance on the Bonds in the Insured Trusts" in Prospectus Part
II.

For an explanation of the footnotes used on this page, see "Notes to Portfolio".
</TABLE>


NOTES TO PORTFOLIO

(1) The Bonds 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. Contracts to
    acquire the Bonds were entered into during the period from May 15, 1998 to
    May 20, 1998.
(2) Other information regarding the Bonds is as follows:


                             COST TO           PROFIT (LOSS)
                             SPONSOR            TO SPONSOR
                         ---------------      ---------------
                           $ 8,533,321           $ 85,636
- -----------

    The breakdown of the Preinsured Bond Insurers is as follows: AMBAC Assurance
    40%, Financial Guaranty 3%, MBIA 51% and FSA 6%.
    The Sponsor may have entered into contracts which hedge interest rate
    fluctuations on certain Bonds. The cost of any such contracts and the
    corresponding gain or loss is included in the Cost to Sponsor. Bonds marked
    by "##" following the maturity date have been purchased on a "when, as and
    if issued" or "delayed delivery" basis. Interest on these Bonds 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. "#" prior to the coupon rate indicates that the Bond
    was issued at an original issue discount. See "The Trusts--Risk Factors" in
    Prospectus Part II. The tax effect of Bonds issued at an original issue
    discount is described in "Federal Tax Status" in Prospectus Part II.
    
(3) All ratings are by Standard & Poor's unless otherwise indicated. "*"
    indicates that the rating of the Bond is by Moody's. "o" indicates that the
    rating is contingent upon receipt by the rating agency of a policy of
    insurance obtained by the issuer of the bonds. "N/R" indicates that the
    rating service did not provide a rating for that Bond. For a brief
    description of the ratings see "Description of Ratings" in the Information
    Supplement.
(4) This is the year in which each Bond is initially or currently callable and
    the call price for that year. Each Bond 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. 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. See "The Trusts--Risk Factors" in
    Prospectus Part II.

   UNDERWRITING. The Underwriters named below have purchased Units in the
following amounts from the Sponsor. For additional information regarding the
Underwriters, including information relating to compensation and benefits
received by the Underwriters, see "Public Offering--Sponsor and Underwriter
Compensation" in Prospectus Part II.

   LETTER OF INTENT. A purchaser desiring to purchase during a 13 month period
$500,000 or more of any combination of series of Van Kampen American Capital
unit investment trusts may qualify for a reduced sales charge by signing a
nonbinding Letter of Intent with any single broker-dealer. After signing a
Letter of Intent, at the date total purchases, less redemptions, of units of any
combination of series of Van Kampen American Capital unit investment trusts by a
purchaser (including 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) exceed $500,000,
the selling broker-dealer, bank or other will credit the unitholder with cash as
a retroactive reduction of the sales charge on such units equal to the amount
which would have been paid for the total aggregated sale amount. If a purchaser
does not complete the required purchases under the Letter of Intent within the
13 month period, no such retroactive sales charge reduction shall be made. To
qualify under a Letter of Intent each purchase of units of Van Kampen American
Capital unit investment trusts must equal or exceed $100,000.

                     REPORT OF CERTIFIED PUBLIC ACCOUNTANTS

    To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of Insured Municipals Income Trust, Series 399 (included in
Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 301):
   We have audited the accompanying statement of condition and the portfolio of
Insured Municipals Income Trust, Series 399 (included in Insured Municipals
Income Trust and Investors' Quality Tax-Exempt Trust, Multi-Series 301) as of
May 22, 1998. The statement of condition and portfolio 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 an irrevocable letter of credit deposited to purchase tax-exempt
bonds 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, Series 399 (included in Insured Municipals Income Trust and Investors'
Quality Tax-Exempt Trust, Multi-Series 301) as of May 22, 1998, in conformity
with generally accepted accounting principles.

               FLORIDA INSURED MUNICIPALS INCOME TRUST, SERIES 121



- --------------------------------------------------------------------------------





   Florida Insured Municipals Income Trust, Series 121 (the "Trust") (included
in Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 301 (the "Fund")) consists of interest-bearing obligations issued
by or on behalf of municipalities and other governmental authorities, the
interest on which is, in the opinion of bond counsel to the issuer, exempt from
all Federal income taxes under existing law and the Units are exempt to the
extent described herein from certain Florida taxes when held by residents of
Florida (the "Bonds"). The objective of the Trust is Federal tax-exempt income
and conservation of capital through an investment in a diversified portfolio of
tax-exempt bonds. The Units of the Trust are rated "AAA" by Standard & Poor's.
The Trust is referred to herein as the "State Trust" or "Insured Trust".

   The Trust consists of 10 issues of Bonds. One of the Bonds 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) as follows: Health Care, 2 (27%); General Purpose, 3 (18%);
Transportation, 2 (18%); General Obligation, 1 (17%); Wholesale Electric, 1
(12%) and Water and Sewer, 1 (8%). The dollar weighted average maturity of the
Bonds is 28 years.

                                              Monthly                Semi-Annual
                                         -------------            ------------
 Estimated Current Return:                     4.60%                    4.65%
 Estimated Long Term Return:                   4.62%                    4.67%
 CUSIP:                                     34074C-34-3              34074C-35-0
    

   Estimated Current Return shows the estimated cash to be received each year
from the Bonds (net of estimated annual expenses) divided by the Public Offering
Price (including the sales charge).
   Estimated Long-Term Return shows the estimated return over the estimated life
of the Trust. This is based on an average of the yields to maturity (or an
earlier call date) of the Bonds adjusted to reflect the sales charge and
estimated expenses. The average yield for the portfolio is derived by weighting
each Bond's yield by its value and the time remaining to the call or maturity
date, depending on how the Bond is priced. Unlike Estimated Current Return,
Estimated Long-Term Return accounts for maturities, discounts and premiums of
the Bonds.
   No return calculation can predict your actual return because returns vary
with purchase price, sales charges, the length of the time Units are held and
changes in portfolio composition, interest income and expenses. The estimated
returns are designed to show a comparison rather than a prediction of returns. A
yield calculation, which is more comparable to a calculation of an individual
bond, may be higher or lower than these estimated returns which are more
comparable to return calculations of other investment products.

(1) Because certain of the Bonds may from time to time under certain
    circumstances be sold or redeemed or will be called or mature in accordance
    with their terms (including the call or sale of zero coupon bonds at prices
    less than par value), there is no guarantee that the value of each Unit at
    Trust termination will be equal to the Principal Amount of Bonds per Unit.
(2) After the First Settlement Date (May 28, 1998), Unitholders will pay accrued
    interest from such date to the settlement date less distributions from the
    Interest Account after the First Settlement Date.
(3) This is based on estimated cash flows per Unit which will vary with changes
    in expenses, interest rates and maturity, call, exchange or sale of the
    Bonds. Estimated cash flows are set forth in the Information Supplement or
    are available upon request.
(4) Excludes insurance expenses.
(5) This fee is assessed per $1,000 principal amount of Bonds. Other fees are
assessed per Unit.

All of the Bonds are insured either by one of the Preinsured Bond Insurers as
indicated in the Bond name or by a Portfolio Insurer under a portfolio insurance
policy. See "Insurance on the Bonds in the Insured Trusts" in Prospectus Part
II.

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


NOTES TO PORTFOLIO

(1) The Bonds 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. Contracts to
    acquire the Bonds were entered into during the period from May 18, 1998 to
    May 20, 1998.
(2) Other information regarding the Bonds is as follows:


                       COST TO           PROFIT (LOSS)
                       SPONSOR            TO SPONSOR

                     $ 2,885,439            $ 20,830
- -----------

    The breakdown of the Preinsured Bond Insurers is as follows: AMBAC Assurance
    12%, Financial Guaranty 18%, MBIA 65% and FSA 5%.
    The Sponsor may have entered into contracts which hedge interest rate
    fluctuations on certain Bonds. The cost of any such contracts and the
    corresponding gain or loss is included in the Cost to Sponsor. Bonds marked
    by "##" following the maturity date have been purchased on a "when, as and
    if issued" or "delayed delivery" basis. Interest on these Bonds 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. "#" prior to the coupon rate indicates that the Bond
    was issued at an original issue discount. See "The Trusts--Risk Factors" in
    Prospectus Part II. The tax effect of Bonds issued at an original issue
    discount is described in "Federal Tax Status" in Prospectus Part II.
    
(3) All ratings are by Standard & Poor's unless otherwise indicated. "*"
    indicates that the rating of the Bond is by Moody's. "o" indicates that the
    rating is contingent upon receipt by the rating agency of a policy of
    insurance obtained by the issuer of the bonds. "N/R" indicates that the
    rating service did not provide a rating for that Bond. For a brief
    description of the ratings see "Description of Ratings" in the Information
    Supplement.
(4) This is the year in which each Bond is initially or currently callable and
    the call price for that year. Each Bond 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. 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. See "The Trusts--Risk Factors" in
    Prospectus Part II.

   
   FLORIDA RISK FACTORS. The financial condition of the State of Florida is
affected by various national, economic, social and environmental policies and
conditions. Additionally, Constitutional and statutory limitations imposed on
the State and its local governments concerning taxes, bond indebtedness and
other matters may constrain the revenue-generating capacity of the State and its
local governments and, therefore, the ability of the issuers of the Bonds to
satisfy their obligations. The State Constitution and statutes mandate that the
State budget, as a whole, and each separate fund within the State budget, be
kept in balance from currently available revenues each fiscal year.
Additionally, the State Constitution prohibits issuance of State obligations to
fund State operations.
   The economic vitality of the State and its various regions and, therefore,
the ability of the State and its local governments to satisfy the Bonds, are
affected by numerous factors. The State continues to be dependent on the
construction and construction related manufacturing industries. These industries
tend to be highly cyclical and there is no assurance that Florida's rapid
population growth, which drove these industries in the past, will continue.
Tourism is also one of the State's most important industries. Because many
international travelers visit Florida, an increase in the value of the U.S.
dollar adversely affects this industry. Moreover, Florida could be impacted by
problems in the agricultural sector, including crop failures, severe weather
conditions or other agricultural-related problems, particularly with regard to
the citrus and sugar industries.
   The State is a party to numerous lawsuits in which an adverse final decision
could materially affect the State's governmental operations and consequently its
ability to pay debt service on its obligations.
   The State maintains a bond rating of Aa2 and AA+ from Moody's and Standard &
Poor's, respectively, on the majority of its general obligation bonds, although
the rating of a particular series of revenue bonds relates primarily to the
project, facility, or other revenue resource from which such series derives
funds for repayment.
   Further information concerning Florida risk factors may be obtained upon
request to the Sponsor as described in "Additional Information" appearing in
Prospectus Part II.
    TAX STATUS. For a discussion of the Federal tax status of income earned on
Florida IM-IT Trust Units, see "Federal Tax Status" in Prospectus Part II. The
Bonds were accompanied by opinions of Bond Counsel to the respective issuers
thereof to the effect that the Bonds were exempt from the Florida intangibles
tax. Neither the Sponsor nor its counsel have independently reviewed such
opinions or examined the Bonds to be deposited in and held by the Florida IM-IT
Trust and have assumed the correctness as of the date of deposit of the opinions
of Bond Counsel.
   "Non-Corporate Unitholder" means a Unitholder of the Florida Trust who is an
individual not subject to the Florida state income tax on corporations under
Chapter 220, Florida Statutes and "Corporate Unitholder" means a Unitholder of
the Florida Trust that is a corporation, bank or savings association or other
entity subject to Florida state income tax on corporations or franchise tax
imposed on banks or savings associations under Chapter 220, Florida Statutes.
   In the opinion of Chapman and Cutler, counsel to the Sponsor, under existing
law:
    For Florida state income tax purposes, the Florida IM-IT Trust will not be
subject to the Florida income tax imposed by Chapter 220, Florida Statutes.
Because Florida does not impose an income tax on individuals, Non-Corporate
Unitholders residing in Florida will not be subject to any Florida income
taxation on income realized by the Florida IM-IT Trust. Any amounts paid to the
Florida IM-IT Trust or to Non-Corporate Unitholders under an insurance policy
issued to the Florida IM-IT Trust or the Sponsor which represent maturing
interest on defaulted obligations held by the Trustee will not be subject to the
Florida income tax imposed by Chapter 220, Florida Statutes.
   Corporate Unitholders with commercial domiciles in Florida will be subject to
Florida income or franchise taxation on income realized by the Florida IM-IT
Trust and on payments of interest pursuant to any insurance policy to the extent
such income constitutes "non business income" as defined by Chapter 220 or is
otherwise allocable to Florida under Chapter 220. Other Corporate Unitholders
will be subject to Florida income or franchise taxation on income realized by
the Florida IM-IT Trust (or on payments of interest pursuant to any insurance
policy) only to the extent that the income realized does not constitute
"non-business income" as defined by Chapter 220 and if such income is otherwise
allocable to Florida under Chapter 220.
   Units will be subject to Florida estate tax only if held by Florida
residents. However, the Florida estate tax is limited to the amount of the
credit for state death taxes provided for in Section 2011 of the Internal
Revenue Code.
   Neither the Bonds nor the Units will be subject to the Florida ad valorem 
property tax, the Florida  intangible  personal  property tax or the Florida 
sales or use tax.
   Chapman and Cutler has expressed no opinion with respect to taxation under
any other provision of Florida law. Ownership of the Units may result in
collateral Florida tax consequences to certain taxpayers. Prospective investors
should consult their tax advisors as to the applicability of any such collateral
consequences.
    

   UNDERWRITING. The Underwriters named below have purchased Units in the
following amounts from the Sponsor. For additional information regarding the
Underwriters, including information relating to compensation and benefits

Compensation" in Prospectus Part II.

   LETTER OF INTENT. A purchaser desiring to purchase during a 13 month period
$500,000 or more of any combination of series of Van Kampen American Capital
unit investment trusts may qualify for a reduced sales charge by signing a
nonbinding Letter of Intent with any single broker-dealer. After signing a
Letter of Intent, at the date total purchases, less redemptions, of units of any
combination of series of Van Kampen American Capital unit investment trusts by a
purchaser (including 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) exceed $500,000,
the selling broker-dealer, bank or other will credit the unitholder with cash as
a retroactive reduction of the sales charge on such units equal to the amount
which would have been paid for the total aggregated sale amount. If a purchaser
does not complete the required purchases under the Letter of Intent within the
13 month period, no such retroactive sales charge reduction shall be made. To
qualify under a Letter of Intent each purchase of units of Van Kampen American
Capital unit investment trusts must equal or exceed $100,000.

                     REPORT OF CERTIFIED PUBLIC ACCOUNTANTS

    To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of Florida Insured Municipals Income Trust, Series 121
(included in Insured Municipals Income Trust and Investors' Quality Tax-Exempt
Trust, Multi-Series 301):
   We have audited the accompanying statement of condition and the portfolio of
Florida Insured Municipals Income Trust, Series 121 (included in Insured
Municipals Income Trust and Investors' Quality Tax-Exempt Trust, Multi-Series
301) as of May 22, 1998. The statement of condition and portfolio 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 an irrevocable letter of credit deposited to purchase tax-exempt
bonds 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 Florida Insured Municipals
Income Trust, Series 121 (included in Insured Municipals Income Trust and
Investors' Quality Tax-Exempt Trust, Multi-Series 301) as of May 22, 1998, in
conformity with generally accepted accounting principles.

                                PROSPECTUS PART I

              MICHIGAN INSURED MUNICIPALS INCOME TRUST, SERIES 150



- --------------------------------------------------------------------------------





   Michigan Insured Municipals Income Trust, Series 150 (the "Trust") (included
in Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 301 (the "Fund")) consists of interest-bearing obligations issued
by or on behalf of municipalities and other governmental authorities, the
interest on which is, in the opinion of bond counsel to the issuer, exempt from
all Federal income taxes under existing law and exempt to the extent described
herein from Michigan state and local taxes when held by residents of Michigan
(the "Bonds"). The objective of the Trust is Federal and Michigan tax-exempt
income and conservation of capital through an investment in a diversified
portfolio of tax-exempt bonds. The Units of the Trust are rated "AAA" by
Standard & Poor's. The Trust is referred to herein as the "State Trust" or
"Insured Trust".

   The Trust consists of 9 issues of Bonds. Four of the Bonds 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) as follows: General Obligation, 4 (53%); Health Care, 1 (16%);
Water and Sewer, 1 (16%); Public Building, 1 (9%); General Purpose, 1 (3%) and
Higher Education, 1 (3%). The dollar weighted average maturity of the Bonds is
27 years.

                                              Monthly                Semi-Annual
                                         -------------            ------------
 Estimated Current Return:                     4.59%                    4.64%
 Estimated Long Term Return:                   4.62%                    4.67%
 CUSIP:                                     59452Q-79-6              59452Q-80-4
    

   Estimated Current Return shows the estimated cash to be received each year
from the Bonds (net of estimated annual expenses) divided by the Public Offering
Price (including the sales charge).
   Estimated Long-Term Return shows the estimated return over the estimated life
of the Trust. This is based on an average of the yields to maturity (or an
earlier call date) of the Bonds adjusted to reflect the sales charge and
estimated expenses. The average yield for the portfolio is derived by weighting
each Bond's yield by its value and the time remaining to the call or maturity
date, depending on how the Bond is priced. Unlike Estimated Current Return,
Estimated Long-Term Return accounts for maturities, discounts and premiums of
the Bonds.
   No return calculation can predict your actual return because returns vary
with purchase price, sales charges, the length of the time Units are held and
changes in portfolio composition, interest income and expenses. The estimated
returns are designed to show a comparison rather than a prediction of returns. A
yield calculation, which is more comparable to a calculation of an individual
bond, may be higher or lower than these estimated returns which are more
comparable to return calculations of other investment products.

(1) Because certain of the Bonds may from time to time under certain
    circumstances be sold or redeemed or will be called or mature in accordance
    with their terms (including the call or sale of zero coupon bonds at prices
    less than par value), there is no guarantee that the value of each Unit at
    Trust termination will be equal to the Principal Amount of Bonds per Unit.
(2) After the First Settlement Date (May 28, 1998), Unitholders will pay accrued
    interest from such date to the settlement date less  distributions  from the
    Interest Account after the First Settlement Date.
(3) This is based on estimated cash flows per Unit which will vary with changes
    in expenses, interest rates and maturity, call, exchange or sale of the
    Bonds. Estimated cash flows are set forth in the Information Supplement or
    are available upon request.
(4) Excludes insurance expenses.
(5) This fee is assessed per $1,000 principal amount of Bonds. Other fees are
    assessed per Unit.

All of the Bonds are insured either by one of the Preinsured Bond Insurers as
indicated in the Bond name or by a Portfolio Insurer under a portfolio insurance
policy. See "Insurance on the Bonds in the Insured Trusts" in Prospectus Part
II.

For an explanation of the footnotes used on this page, see "Notes to Portfolio".
</TABLE>


NOTES TO PORTFOLIO

(1) The Bonds 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. Contracts to
    acquire the Bonds were entered into during the period from May 19, 1998 to
    May 21, 1998.
(2) Other information regarding the Bonds is as follows:


                            COST TO           PROFIT (LOSS)
                            SPONSOR            TO SPONSOR

                          $ 3,033,663            $ 34,277
- -----------

    The breakdown of the Preinsured Bond Insurers is as follows: AMBAC Assurance
3%, Financial Guaranty 40%, MBIA 35% and FSA 22%.
    The Sponsor may have entered into contracts which hedge interest rate
    fluctuations on certain Bonds. The cost of any such contracts and the
    corresponding gain or loss is included in the Cost to Sponsor. Bonds marked
    by "##" following the maturity date have been purchased on a "when, as and
    if issued" or "delayed delivery" basis. Interest on these Bonds 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. "#" prior to the coupon rate indicates that the Bond
    was issued at an original issue discount. See "The Trusts--Risk Factors" in
    Prospectus Part II. The tax effect of Bonds issued at an original issue
    discount is described in "Federal Tax Status" in Prospectus Part II.
    
(3) All ratings are by Standard & Poor's unless otherwise indicated. "*"
    indicates that the rating of the Bond is by Moody's. "o" indicates that the
    rating is contingent upon receipt by the rating agency of a policy of
    insurance obtained by the issuer of the bonds. "N/R" indicates that the
    rating service did not provide a rating for that Bond. For a brief
    description of the ratings see "Description of Ratings" in the Information
    Supplement.
(4) This is the year in which each Bond is initially or currently callable and
    the call price for that year. Each Bond 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. 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. See "The Trusts--Risk Factors" in
    Prospectus Part II.
   
   MICHIGAN RISK FACTORS. The financial condition of the State of Michigan is
affected by various national, economic, social and environmental policies and
conditions. Additionally, Constitutional and statutory limitations imposed on
the State and its local governments concerning taxes, bond indebtedness and
other matters may constrain the revenue-generating capacity of the State and its
local governments and, therefore, the ability of the issuers of the Bonds to
satisfy their obligations. The State's Constitution limits the amount of total
State revenues that may be raised from taxes and other sources. State revenues
(excluding federal aid and revenues used for payment of principal of and
interest on general obligation bonds) in any fiscal year are limited to a
specified percentage of State personal income in the prior calendar year or the
average thereof in the prior three calendar years, whichever is greater. The
State may raise taxes in excess of the limit in emergency situations.
   The economic vitality of the State and its various regions and, therefore,
the ability of the State and its local governments to satisfy the Bonds, are
affected by numerous factors. The economy of the State continues to be dependent
on manufacturing, tourism, and agriculture. These sectors tend to be cyclical
and are facing increasing competition from foreign producers.
   The State is a party to numerous lawsuits in which an adverse final decision
could materially affect the State's governmental operations and consequently its
ability to pay debt service on its obligations.
   As of March 1, 1997, all outstanding general obligation bonds of the state
were rated "Aa" by Moody's and "AA" by Fitch IBCA, Inc. (formerly Fitch
Investors Service, L.P.). In January 1998, Standard & Poor's raised its rating
on the State's general obligation bonds to "AA+". In April, 1998, Fitch IBCA,
Inc., raised its rating on the State's general obligfation bonds to AA+.
   Further information concerning Michigan risk factors may be obtained upon
request to the Sponsor as described in "Additional Information" appearing in
Prospectus Part II.
   TAX STATUS.  For a  discussion  of the Federal tax status of income earned o
Michigan  IM-IT  Trust  Units,  see  "Federal  Tax Status" in Part II of this
Prospectus.
    In the opinion of Miller, Canfield, Paddock and Stone, P.L.C., special
counsel to the Fund for Michigan tax matters, under existing Michigan law: The
Michigan IM-IT Trust and the owners of Units will be treated for purposes of the
Michigan income tax laws and the Single Business Tax in substantially the same
manner as they are for purposes of the Federal income tax laws, as currently
enacted. Accordingly, we have relied upon the opinion of Messrs. Chapman and
Cutler as to the applicability of Federal income tax under the Internal Revenue
Code of 1986 to the Michigan IM-IT Trust and the Unitholders.
   Under the income tax laws of the State of Michigan, the Michigan IM-IT Trust
is not an association taxable as a corporation; the income of the Michigan IM-IT
Trust will be treated as the income of the Unitholders and be deemed to have
been received by them when received by the Michigan IM-IT Trust. Interest on the
underlying Bonds which is exempt from tax under these laws when received by
Michigan IM-IT Trust will retain its status as tax exempt interest to the
Unitholders.
   For purposes of the foregoing Michigan tax laws, each Unitholder will be
considered to have received his pro rata share of Bond interest when it is
received by the Michigan IM-IT Trust, and each Unitholder will have a taxable
event when the Michigan IM-IT Trust disposes of a Bond (whether by sale,
exchange, redemption or payment at maturity) or when the Unitholder redeems or
sells his Certificate to the extent the transaction constitutes a taxable event
for Federal income tax purposes. The tax cost of each unit to a Unitholder will
be established and allocated for purposes of these Michigan tax laws in the same
manner as such cost is established and allocated for Federal income tax
purposes.
   The Michigan Intangibles Tax was totally repealed effective January 1, 1998.
   The Michigan Single Business Tax replaced the tax on corporate and financial
institution income under the Michigan Income Tax, and the Intangible Tax with
respect to those intangibles of persons subject to the Single Business Tax the
income from which would be considered in computing the Single Business Tax.
Persons are subject to the Single Business Tax only if they are engaged in
"business activity", as defined in the Act. Under the Single Business Tax, both
interest received by the Michigan IM-IT Trust on the underlying Bonds and any
amount distributed from the Michigan IM-IT Trust to a Unitholder, if not
included in determining taxable income for Federal income tax purposes, is also
not included in the adjusted tax base upon which the Single Business Tax is
computed, of either the Michigan IM-IT Trust or the Unitholders. If the Michigan
IM-IT Trust or the Unitholders have a taxable event for Federal income tax
purposes when the Michigan IM-IT Trust disposes of a Bond (whether by sale,
exchange, redemption or payment at maturity) or the Unitholder redeems or sells
his Certificate, an amount equal to any gain realized from such taxable event
which was included in the computation of taxable income for Federal income tax
purposes (plus an amount equal to any capital gain of an individual realized in
connection with such event but excluded in computing that individual's Federal
taxable income) will be included in the tax base against which, after
allocation, apportionment and other adjustments, the Single Business Tax is
computed. The tax base will be reduced by an amount equal to any capital loss
realized from such a taxable event, whether or not the capital loss was deducted
in computing Federal taxable income in the year the loss occurred. Unitholders
should consult their tax advisor as to their status under Michigan law.
   Any proceeds paid under an insurance policy issued to the Trustee of the
Trust, or paid under individual policies obtained by issuers of Bonds, which,
when received by the Unitholders, represent maturing interest on defaulted
obligations held by the Trustee, will be excludable from the Michigan income tax
laws and the Single Business Tax if, and to the same extent as, such interest
would have been so excludable if paid by the issuer of the defaulted
obligations. While treatment under the Michigan Intangibles Tax is not premised
upon the characterization of such proceeds under the Internal Revenue Code, the
Michigan Department of Treasury should adopt the same approach as under the
Michigan income tax laws and the Single Business Tax
   As the Tax Reform Act of 1986 eliminated the capital gain deduction for tax
years beginning after December 31, 1986, the federal adjusted gross income, the
computation base for the Michigan Income Tax, of a Unitholder will be increased
accordingly to the extent such capital gains are realized when the Michigan
IM-IT Trust disposes of a Bond or when the Unitholder redeems or sells a Unit,
to the extent such transaction constitutes a taxable event for Federal income
tax purposes.

   LETTER OF INTENT. A purchaser desiring to purchase during a 13 month period
$500,000 or more of any combination of series of Van Kampen American Capital
unit investment trusts may qualify for a reduced sales charge by signing a
nonbinding Letter of Intent with any single broker-dealer. After signing a
Letter of Intent, at the date total purchases, less redemptions, of units of any
combination of series of Van Kampen American Capital unit investment trusts by a
purchaser (including 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) exceed $500,000,
the selling broker-dealer, bank or other will credit the unitholder with cash as
a retroactive reduction of the sales charge on such units equal to the amount
which would have been paid for the total aggregated sale amount. If a purchaser
does not complete the required purchases under the Letter of Intent within the
13 month period, no such retroactive sales charge reduction shall be made. To
qualify under a Letter of Intent each purchase of units of Van Kampen American
Capital unit investment trusts must equal or exceed $100,000.

                     REPORT OF CERTIFIED PUBLIC ACCOUNTANTS

   To the Board of Directors of Van Kampen American Capital  Distributors,  Inc.
and the Unitholders of Michigan Insured  Municipals  Income Trust,  Series 150
(included in Insured Municipals Income Trust and Investors' Quality Tax-Exempt 
Trust, Multi-Series 301):
   We have audited the accompanying statement of condition and the portfolio of
Michigan Insured Municipals Income Trust, Series 150 (included in Insured
Municipals Income Trust and Investors' Quality Tax-Exempt Trust, Multi-Series
301) as of May 22, 1998. The statement of condition and portfolio 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 an irrevocable letter of credit deposited to purchase tax-exempt
bonds 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 Michigan Insured Municipals
Income Trust, Series 150 (included in Insured Municipals Income Trust and
Investors' Quality Tax-Exempt Trust, Multi-Series 301) as of May 22, 1998, in
conformity with generally accepted accounting principles.

                                PROSPECTUS PART I

          NORTH CAROLINA INVESTORS' QUALITY TAX-EXEMPT TRUST, SERIES 94


- --------------------------------------------------------------------------------



   North Carolina Investors' Quality Tax-Exempt Trust, Series 94 (the "Trust")
(included in Insured Municipals Income Trust and Investors' Quality Tax-Exempt
Trust, Multi-Series 301 (the "Fund")) consists of interest-bearing obligations
issued by or on behalf of municipalities and other governmental authorities, the
interest on which is, in the opinion of bond counsel to the issuer, exempt from
all Federal income taxes under existing law and exempt to the extent described
herein from North Carolina state and local taxes when held by residents of North
Carolina (the "Bonds"). The objective of the Trust is Federal and North Carolina
tax-exempt income and conservation of capital through an investment in a
diversified portfolio of tax-exempt bonds. The Trust is referred to herein as
the "State Trust" or "Quality Trust".

   The Trust consists of 9 issues of Bonds. One of the Bonds 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) as follows: Health Care, 2 (27%); Wholesale Electric, 2 (26%); Higher
Education, 2 (17%); Public Building, 1 (12%); Retail Electric/Gas/Telephone, 1
(10%) and General Obligation, 1 (8%). The dollar weighted average maturity of
the Bonds is 25 years.


                                              Monthly             Semi-Annual
                                        ------------------    ------------------
 Estimated Current Return:                     4.57%                  4.61%
 Estimated Long Term Return:                   4.57%                  4.61%
 CUSIP:                                     65820D-36-7            65820D-37-5
    

   Estimated Current Return shows the estimated cash to be received each year
from the Bonds (net of estimated annual expenses) divided by the Public Offering
Price (including the sales charge).
   Estimated Long-Term Return shows the estimated return over the estimed life
of the Trust. This is based on an average of the yields to maturity (or an
earlier call date) of the Bonds adjusted to reflect the sales charge and
estimated expenses. The average yield for the portfolio is derived by weighting
each Bond's yield by its value and the time remaining to the call or maturity
date, depending on how the Bond is priced. Unlike Estimated Current Return,
Estimated Long-Term Return accounts for maturities, discounts and premiums of
the Bonds.
   No return calculation can predict your actual return because returns vary
with purchase price, sales charges, the length of time Units are held and
changes in portfolio composition, interest income and expenses. The estimated
returns are designed to show a comparison rather than a prediction of returns. A
yield calculation, which is more comparable to a calculation on an individual
bond, may be higher or lower than these estimated returns which are more
comparable to return calculations of other investment products.

(1) Because certain of the Bonds may from time to time under certain
    circumstances be sold or redeemed or will be called or mature in accordance
    with their terms (including the call or sale of zero coupon bonds at prices
    less than par value), there is no guarantee that the value of each Unit at
    Trust termination will be equal to the Principal Amount of Bonds per Unit.
(2) After the First Settlement Date (May 28, 1998), Unitholders will pay accrued
    interest from such date to the settlement date less  distributions  from the
    Interest Account after the First Settlement Date.
(3) This is based on estimated cash flows per Unit which will vary with changes
    in expenses, interest rates and maturity, call, exchange or sale of the
    Bonds. Estimated cash flows are set forth in the Information Supplement or
    are available upon request.
(4) This fee is assessed per $1,000 principal amount of Bonds. Other fees are
    assessed per Unit.

    affiliate of the Trustee, has been deposited with the Trustee. Contracts to
    acquire the Bonds were entered into during the period from April 15, 1998 to
    May 18, 1998.
(2) Other information regarding the Bonds is as follows:

                            COST TO           PROFIT (LOSS)
                            SPONSOR            TO SPONSOR
                        ---------------      ---------------
                          $ 1,906,496            $ 28,798
- -----------


    The Sponsor may have entered into contracts which hedge interest rate
    fluctuations on certain Bonds. The cost of any such contracts and the
    corresponding gain or loss is included in the Cost to Sponsor. Bonds marked
    by "##" following the maturity date have been purchased on a "when, as and
    if issued" or "delayed delivery" basis. Interest on these Bonds 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. "#" prior to the coupon rate indicates that the Bond
    was issued at an original issue discount. See "The Trusts--Risk Factors" in
    Prospectus Part II. The tax effect of Bonds issued at an original issue
    discount is described in "Federal Tax Status" in Prospectus Part II.
    
(3) All ratings are by Standard & Poor's unless otherwise indicated. "*"
    indicates that the rating of the Bond is by Moody's. "o" indicates that the
    rating is contingent upon receipt by the rating agency of a policy of
    insurance obtained by the issuer of the bonds. "N/R" indicates that the
    rating service did not provide a rating for that Bond. For a brief
    description of the ratings see "Description of Ratings" in the Information
    Supplement.
(4) This is the year in which each Bond is initially or currently callable and
    the call price for that year. Each Bond 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. 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. See "The Trusts--Risk Factors" in
    Prospectus Part II.
   
   NORTH CAROLINA RISK FACTORS. The financial condition of the State of North
Carolina is affected by various national, economic, social and environmental
policies and conditions. Additionally, Constitutional and statutory limitations
imposed on the State and its local governments concerning taxes, bond
indebtedness and other matters may constrain the revenue-generating capacity of
the State and its local governments and, therefore, the ability of the issuers
of the Bonds to satisfy their obligations.
      The economic vitality of the State and its various regions and, therefore,
the ability of the State and its local governments to satisfy the Bonds, are
affected by numerous factors. The State's economic base is diversified,
consisting of manufacturing, construction and service industries, supplemented
by rural areas with selective commercial agriculture. The State has a relatively
high wage labor market which has resulted in the State's business sector
becoming more vulnerable to competitive pressures.
      The State is a party to numerous lawsuits in which an adverse final
decision could materially affect the State's governmental operations and
consequently its ability to pay debt service on its obligations.
      The State of North Carolina currently maintains a "triple A" bond rating
from Standard & Poor's and Moody's on its general obligation indebtedness.
Further information concerning North Carolina risk factors may be obtained upon
request to the Sponsor as described in "Additional Information" appearing in
Prospectus Part II.
   TAX STATUS. For a discussion of the Federal tax status of income earned on
North Carolina Quality Trust Units, see "Federal Tax Status" in Prospectus Part
II. 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 Unitholder.
   (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.
    

   UNDERWRITING. The Underwriters named below have purchased Units in the
following amounts from the Sponsor. For additional information regarding the
Underwriters, including information relating to compensation and benefits
received by the Underwriters, see "Public Offering--Sponsor and Underwriter
Compensation" in Prospectus Part II.

   LETTER OF INTENT. A purchaser desiring to purchase during a 13 month period
$500,000 or more of any combination of series of Van Kampen American Capital
unit investment trusts may qualify for a reduced sales charge by signing a
nonbinding Letter of Intent with any single broker-dealer. After signing a
Letter of Intent, at the date total purchases, less redemptions, of units of any
combination of series of Van Kampen American Capital unit investment trusts by a
purchaser (including 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) exceed $500,000,
the selling broker-dealer, bank or other will credit the unitholder with cash as
a retroactive reduction of the sales charge on such units equal to the amount
which would have been paid for the total aggregated sale amount. If a purchaser
does not complete the required purchases under the Letter of Intent within the
13 month period, no such retroactive sales charge reduction shall be made. To
qualify under a Letter of Intent each purchase of units of Van Kampen American
Capital unit investment trusts must equal or exceed $100,000.

                     REPORT OF CERTIFIED PUBLIC ACCOUNTANTS

   To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of North Carolina Investors' Quality Tax-Exempt Trust,
Series 94 (included in Insured Municipals Income Trust and Investors' Quality
Tax-Exempt Trust, Multi-Series 301):
   We have audited the accompanying statement of condition and the portfolio of
North Carolina Investors' Quality Tax-Exempt Trust, Series 94 (included in
Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 301) as of May 22, 1998. The statement of condition and portfolio
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 an irrevocable letter of credit deposited to purchase tax-exempt
bonds 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 North Carolina Investors'
Quality Tax-Exempt Trust, Series 94 (included in Insured Municipals Income Trust
and Investors' Quality Tax-Exempt Trust, Multi-Series 301) as of May 22, 1998,
in conformity with generally accepted accounting principles.

INSURED MUNICIPALS INCOME TRUST, INSURED MULTI-SERIES AND
INSURED MUNICIPALS INCOME TRUST AND INVESTORS' QUALITY TAX-EXEMPT TRUST,
  MULTI-SERIES
- --------------------------------------------------------------------------------

   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 the
underlying separate unit investment trusts set forth in Prospectus Part I. The
Bonds are interest-bearing obligations issued by or on behalf of municipalities
and other governmental authorities, the interest on which is exempt from all
Federal income taxes under existing law in the opinion of bond counsel to the
issuer. In addition, the interest income of each State Trust is, in the opinion
of bond counsel to the issuer, exempt to the extent indicated from state and
local taxes, when held by residents of the state where the issuers of the Bonds
are located. Except in specific instances as noted in Prospectus Part I, the
information contained in this Prospectus Part II shall apply to each Trust in
its entirety.
   "AAA" RATING FOR THE INSURED TRUSTS. Insurance guaranteeing the payments of
principal and interest, when due, on the Bonds in each Insured Trust has been
obtained from a municipal bond insurance company. See "Insurance on the Bonds in
the Insured Trusts". Insurance relates only to the Bonds and not to the Units or
to the market value thereof. As a result of such insurance, the Units of each
Insured Trust have received a rating of "AAA" by Standard & Poor's, A Division
of the McGraw-Hill Companies ("Standard & Poor's"). Units of the Trusts are not
insured by the FDIC, are not deposits or other obligations of, or guaranteed by,
any government agency and are subject to investment risk, including possible
loss of the principal amount invested.
   PUBLIC OFFERING PRICE. The Public Offering Price of Units during the initial
offering period includes the aggregate offering price of the Bonds, the
applicable sales charge, cash, if any, in the Principal Account of the Trust,
and accrued interest, if any. Sales charges for the Trusts are set forth under
"Public Offering--General." During the initial offering period, the sales charge
is reduced for sales involving at least 100 Units.
   ESTIMATED CURRENT AND LONG-TERM RETURNS. The Estimated Current Returns and
Estimated Long-Term Returns to Unitholders are described on the cover of 
Prospectus Part I. See "Estimated Current and Long-Term Returns."
   DISTRIBUTION OPTIONS. Unitholders may elect to receive distributions on a
monthly or semi-annual basis. See "Rights of Unitholders--Distributions of
Interest and Principal". Those indicating no choice will be deemed to have
chosen the monthly distribution plan.
   MARKET FOR UNITS. Although not obligated to do so, the Sponsor intends to,
and certain of the other Underwriters may, maintain a secondary market for the
Units. If a secondary market is not available, a Unitholder will always be able
to redeem his Units through the Trustee on any business day. See "Rights of
Unitholders--Redemption of Units" and "Public Offering--Market for Units".
   REINVESTMENT OPTION. Unitholders may reinvest their distributions into Van
Kampen American Capital or Morgan Stanley mutual funds. See "Rights of
Unitholders--Reinvestment Option". Unitholders may also have the option of
exchanging their investment for units of other Van Kampen American Capital unit
investment trusts at a reduced sales charge. Unitholders may obtain a prospectus
for such trusts from the Sponsor.
   RISK FACTORS. An investment in Units should be made with an understanding of
certain risks, including, among other factors, the inability of the issuer or an
insurer, if any, to pay the principal of or interest on a bond when due,
volatile interest rates, early call provisions, and changes to the tax status of
the Bonds. See "The Trusts--Risk Factors".

THE TRUSTS
- --------------------------------------------------------------------------------

         THE FUND. This series of the Insured Municipals Income Trust or the
Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust (the
"Fund"), consists of the underlying separate unit investment trusts described in
Prospectus Part I. 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 Prospectus Part I (the "Date of Deposit") among Van Kampen American
Capital Distributors, Inc., as Sponsor, American Portfolio Evaluation Services,
a division of Van Kampen American Capital Investment Advisory Corp., as
Evaluator, and The Bank of New York, as Trustee.
         The Fund consists of separate portfolios of interest-bearing
obligations issued by or on behalf of states and territories of the United
States, and political subdivisions and authorities thereof, the interest on
which is, in the opinion of recognized bond counsel to the issuing authorities,
excludable from gross income for Federal income tax purposes under existing law.
All issuers of Bonds in a State Trust are located in the state for which the
Trust is named or in United States territories or possessions and their public
authorities; consequently, in the opinion of recognized bond counsel to the Bond
issuers, the interest earned on the Bonds is exempt to the extent indicated in
Prospectus Part I from state and local taxes. Further, in the opinion of bond
counsel to the respective issuers, the interest income of each Bond in a U.S.
Territorial IM-IT Trust is exempt from state, Commonwealth of Puerto Rico and
local income taxation. With the exception of New York and Pennsylvania Trusts,
Units of a State Trust may be purchased only by residents of the state for which
the Trust is named. Units of a New York Trust may be purchased by residents of
New York, Connecticut and Florida. Units of a Pennsylvania Trust may be
purchased by residents of Pennsylvania, Connecticut, Florida, Maryland, New
York, Ohio and West Virginia. State Trusts, other than State Intermediate
Laddered Maturity Trusts or State Intermediate Trusts, are referred to herein as
"Long-Term State Trusts".
         On the Date of Deposit, the Sponsor deposited with the Trustee the
aggregate principal amount of Bonds indicated in the "Summary of Essential
Financial Information" in Prospectus Part I. The Bonds initially consist of
delivery statements relating to contracts for their purchase and cash, cash
equivalents and/or irrevocable letters of credit issued by a financial
institution. Thereafter, the Trustee, in exchange for the Bonds, delivered to
the Sponsor evidence of ownership of the number of Units indicated under
"Summary of Essential Financial Information" in Prospectus Part I.
         The portfolio of any IM-IT, IM-IT Discount, U.S. Territorial IM-IT,
Long-Term State or National Quality 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, State Intermediate Laddered Maturity Trust and
IM-IT Short Intermediate Trust is 12 to 15 years, 5 to 15 years, 5 to 10 years
and 3 to 7 years, respectively. The portfolio of any State Intermediate Laddered
Maturity Trust is structured so that approximately 20% of the Bonds will mature
each year, beginning in approximately the fifth year of the Trust, entitling
each Unitholder to a return of principal. This return of principal may offer
Unitholders the opportunity to respond to changing economic conditions and to
specific financial needs that may arise between the fifth and tenth years of the
Trust. However, the flexibility provided by the return of principal may also
eliminate a Unitholder's ability to reinvest at a rate as high as the yield on
the Bonds which matured.
         Each Unit initially offered represents a fractional undivided interest
in the principal and net income of a Trust. To the extent that any Units are
redeemed by the Trustee, the fractional undivided interest in a Trust
represented by each Unit will increase, although the actual interest in the
Trust will remain unchanged. Units will remain outstanding until redeemed by
Unitholders or until the termination of the Trust Agreement.
         OBJECTIVES AND BOND 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. A State
Intermediate Laddered Maturity Trust has additional objectives of providing
protection against changes in interest rates and investment flexibility through
an investment in a laddered portfolio of intermediate-term interest-bearing
obligations with maturities ranging from approximately 5 to 10 years in which
roughly 20% of the Bonds mature each year beginning in approximately the fifth
year of the Trust. There is, of course, no guarantee that the Trusts will
achieve their objectives. The Fund may be an appropriate investment vehicle for
investors who desire to participate in a portfolio of tax-exempt fixed income
bonds with greater diversification than they might be able to acquire
individually. Insurance guaranteeing the timely payment, when due, of all
principal and interest on the Bonds in each Insured Trust has been obtained from
a municipal bond insurance company. For information relating to insurance on the
Bonds, see "Insurance on the Bonds in the Insured Trusts". In addition, these
bonds are often not available in small amounts.
<PAGE>
         In selecting Bonds for the Trusts, the Sponsor considered the following
factors, among others: (a) either the Standard & Poor's rating of the Bonds was
not less than "BBB-" for Insured Trusts and "A-" for Quality Trusts, or the
Moody's Investors Service, Inc. ("Moody's") rating of the Bonds was not less
than "Baa" for Insured Trusts and "A" for the Quality Trusts, including
provisional or conditional ratings, respectively, (or, if not rated, the Bonds
had credit characteristics sufficiently similar to the credit characteristics of
interest-bearing tax-exempt bonds that were so rated as to be acceptable for
acquisition by the Fund in the opinion of the Sponsor), (b) the prices of the
Bonds relative to other bonds of comparable quality and maturity, (c) the
diversification of Bonds as to purpose of issue and location of issuer and (d)
with respect to the Insured Trusts, the availability and cost of insurance.
After the Date of Deposit, a Bond may cease to be rated or its rating may be
reduced below the minimum required as of the Date of Deposit. Neither event
requires elimination of a Bond from a Trust but may be considered in the
Sponsor's determination as to whether or not to direct the Trustee to dispose of
the Bond (see "Fund Administration--Portfolio Administration").
         RISK FACTORS. The Trusts include certain types of bonds as described on
the cover of Prospectus Part I. An investment in Units should be made with an
understanding of the characteristics of and risks associated with such bonds.
The following is a brief summary of certain of these risks. Additional
information is included in Prospectus Part I and in the Information Supplement.
See "Additional Information". Neither the Sponsor nor the Trustee are liable for
any default, failure or defect in any of the Bonds.
         Certain of the Bonds may be general obligations of a governmental
entity that are backed by the taxing power of the entity. All other Bonds 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, both within a particular classification and between
classifications, depending on numerous factors.
         Mortgage loan obligations 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. 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. A substantial portion of these bonds
will probably be redeemed prior to their scheduled maturities or even prior to
their ordinary call dates. Additionally, unusually high rates of default on the
underlying mortgage loans may reduce revenues available for the payment of
principal of or interest on mortgage revenue bonds.
         Health care revenue bonds have ratings issued for health care
facilities that 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, competition with other health
care facilities, efforts by insurers and governmental agencies to limit rates
and legislation establishing state rate-setting agencies.
         Public utility bond issuers sell wholesale and retail electric power
and gas. General problems of these issuers include difficulty in financing large
construction programs in an inflationary period, costs and delays attributable
to environmental considerations, the difficulty of the capital market in
absorbing utility debt, difficulty in obtaining fuel at reasonable prices, the
effect of energy conservation and government regulations.
         Water and/or sewerage revenue bonds are generally payable from user
fees. The problems of these issuers include the ability to obtain rate
increases, population decline resulting in decreased user fees, financing,
environmental considerations, discovering fresh water and the impact of
"no-growth" zoning ordinances.
         Industrial revenue bonds ("IRBs") have generally been issued under bond
resolutions under which the revenues and receipts payable 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 which may be affected by such things as
cyclicality of revenues and earnings, regulatory and environmental restrictions,
litigation resulting from accidents, extensive competition and financial
deterioration resulting from a corporate restructuring.
         Lease bonds are secured by lease payments of a governmental entity and
are often in the form of certificates of participation. Although the lease bonds
do not constitute general obligations of the municipality for which the
municipality's taxing power is pledged, a lease bond is ordinarily backed by the
municipality's covenant to appropriate for and make the payments due under the
lease bond. However, certain lease bonds 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 bond could result in
insufficient funds available for payment of the bonds secured thereby. Although
"non-appropriation" lease bonds are secured by the leased property, disposition
of the property in the event of foreclosure might prove difficult.
<PAGE>
         Education bond issuers govern the operation of schools, colleges and
universities and revenues are derived mainly from ad valorem taxes or from
tuition, dormitory revenues, grants and endowments. General problems relating to
school bonds include litigation contesting the financing of public education, a
declining percentage of the population consisting of "college" age individuals,
inability to raise tuitions and fees sufficiently and government legislation or
regulations which may adversely affect the revenues or costs of the issuers.
         Transportation bonds are payable from revenues derived from the
ownership and operation of facilities such as airports, bridges, turnpikes, port
authorities, convention centers and arenas. Airport operating income may be
affected by the ability of the airlines to meet their obligations under use
agreements. Payment on bonds related to other facilities may be adversely
affected by reduction in revenues due to such factors as increased cost of
maintenance, decreased use of a facility, lower cost of alternative modes of
transportation, scarcity of fuel and reduction or loss of rents.
         Certain Bonds are payable from revenues derived from the operation of
resource recovery facilities which 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 circumstances
such as destruction or condemnation of a project, void or unenforceable
contracts, changes in the economic availability of raw materials, and operating
supplies or facilities, or other unavoidable changes adversely affecting the
operation of a project.
         Certain Bonds may have been acquired at a market discount from par
value at maturity. The interest rates on these bonds are lower than current
market interest rates for newly issued bonds of comparable rating and type.
Generally, if interest rates for newly issued comparable bonds increase, the
market discount of previously issued bonds will increase, and if interest rates
for newly issued comparable bonds decline, the market discount of previously
issued bonds will decrease. The value of bonds purchased at a market discount
will generally increase in value faster than bonds purchased at a market premium
if interest rates decrease. Conversely, if interest rates increase, the value of
bonds purchased at a market discount will generally decrease faster than bonds
purchased at a market premium. In addition, if interest rates rise, the
prepayment risk of higher yielding, premium bonds and the prepayment benefit for
lower yielding, discount bonds will be reduced. A bond purchased at a market
discount and held to maturity will have a larger portion of its total return in
the form of taxable income and capital gain and less in the form of tax-exempt
interest income than a comparable bond newly issued at current market rates. See
"Federal Tax Status." Market discount attributable to interest changes does not
indicate a lack of market confidence in the issue.
         Certain Bonds may be "original issue discount" bonds which were issued
with interest rates less than rates offered by comparable bonds and were
originally sold at a discount from their par value. These bonds may include
"zero coupon" bonds which are described below. In a stable interest rate
envronment, the market value of an original issue discount bond would tend to
increase more slowly in the early years and in greater increments as the bond
approached maturity. These bonds may be subject to redemption at prices based on
the issue price plus the amount of original issue discount accreted to
redemption plus some premium, if applicable. Under these call provisions, these
bonds may be called prior to maturity at a price less than par value. See
"Federal Tax Status" for a discussion of the tax consequenses of owning these
bonds.
         Certain Bonds may be "zero coupon" bonds. Zero coupon bonds are
purchased at a deep discount because the buyer receives only the right to
receive a final payment at the maturity of the bond and does not receive any
periodic interest payments. The effect of owning these 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 the bond. This implicit reinvestment of
earnings at the same rate eliminates the risk of being unable to reinvest income
at a rate as high as the implicit yield on the discount bond, but at the same
time eliminates the 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 bonds of
comparable quality which pay interest.
         Certain Bonds may have been purchased on a "when, as and if issued" or
"delayed delivery" basis. The delivery of these Bonds may be delayed or may not
occur. Interest on these Bonds begins accruing to the benefit of Unitholders on
their respective dates of delivery. To the extent any Bonds are actually
delivered to a Trust after the expected dates of delivery, Unitholders who
purchase their Units prior to the actual delivery date would be required to
adjust their tax basis in their Units for a portion of the interest accruing on
those Bonds during the interval between their purchase of Units and the actual
delivery of the Bonds. As a result of any adjustment, the Estimated Current
Return during the first year would be slightly lower than stated herein.
Unitholders will be "at risk" with respect to all Bonds (i.e., may derive either
gain or loss from fluctuations in the value of the Bonds) from the date they
order Units.
<PAGE>
         Certain Bonds 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 bond 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 bond price is at a premium over par than when it is at a discount from
par. The exercise of redemption or call provisions generally will 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. See "Portfolio" in Prospectus Part I for a list of the sinking fund and
call provisions, if any, with respect to the Bonds. The Sponsor is unable to
predict all of the circumstances which may result in redemption of a Bond.
         To the best knowledge of the Sponsor, there is no litigation pending as
of the Date of Deposit in respect of any Bonds which might reasonably be
expected to have a material adverse effect upon the Trusts. At any time after
the Date of Deposit, litigation may be initiated on a variety of grounds with
respect to the Bonds. Such litigation may affect the validity of the Bonds or
the tax-free nature of interest payments. While the outcome of litigation can
never be predicted, the Fund has received or will receive opinions of bond
counsel to the issuers of each Bond on the date of issuance to the effect that
the Bonds have been validly issued and interest payments are 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 Bonds.
         Like other investment companies, financial and business organizations
and individuals around the world, the Trusts could be adversely affected if the
computer systems used by the Sponsor, Evaluator or Trustee or other service
providers to the Trusts do not properly process and calculate date-related
information and data from and after January 1, 2000. This is commonly known as
the "Year 2000 Problem." While the Sponsor, Evaluator and Trustee are taking
steps that they believe are reasonably designed to address the Year 2000
Problem, there can be no assurance that these steps will be sufficient to avoid
any adverse impact to the Trusts. The Year 2000 Problem may impact certain
issuers of the Bonds to varying degrees, however, the Sponsor is unable to
predict what impact, if any, the Year 2000 Problem will have on any issuer.

ESTIMATED CURRENT AND LONG-TERM RETURNS
- --------------------------------------------------------------------------------

         The Estimated Current Returns and the Estimated Long-Term Returns as of
the Date of Deposit are set forth on the cover of the Prospectus Part I.
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
Trust and with the principal prepayment, redemption, maturity, exchange or sale
of Bonds. The Public Offering Price will vary with changes in the price of the
Bonds. Accordingly, 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 the Bonds and (2) takes into account the expenses and
sales charge associated with Units. Since the value and estimated retirements of
the Bonds and the expenses of a Trust will change, there is no assurance that
the present Estimated Long-Term Return will be realized in the future. The
Estimated Current Return and Estimated Long-Term Return are expected to differ
because the calculation of Estimated Long-Term Return reflects the estimated
date and amount of principal returned while the Estimated Current Return
calculation includes only net annual interest income and Public Offering Price.
         In order to acquire certain Bonds, it may be necessary for the Sponsor
or Trustee to pay amounts covering accrued interest on the Bonds which exceed
the amounts which will be made available through cash furnished by the Sponsor
on the Date of Deposit. This 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 excess and will be reimbursed when funds become available
from interest payments on the related Bonds. Also, since interest on any "when,
as and if issued" Bonds does not begin accruing as tax-exempt interest income to
the benefit of Unitholders until the date of delivery, the Trustee may reduce
its fee and pay Trust expenses in order to maintain or approach the same
estimated net annual interest income during the first year of the Trust's
operations as described under "Summary of Essential Financial Information" in
Prospectus Part I.

PUBLIC OFFERING
- --------------------------------------------------------------------------------

         GENERAL. Units are offered at the Public Offering Price. During the
initial offering period the Public Offering Price is based on the aggregate
offering price of the Bonds, the sales charge described below, cash, if any, in
the Principal Account and accrued interest, if any. After the initial public
offering period, the secondary market public offering price is based on the bid
prices of the Bonds, the sales charge described below, cash, if any, in the
Principal Account and accrued interest, if any. The minimum purchase in the
primary and secondary market is one Unit.
         The initial offering period sales charges are as follows:

         For purposes of computation of the estimated long-term return life,
Bonds will be deemed to mature on their expressed maturity dates unless: (a) the
Bonds have been called for redemption or are subject to redemption at an earlier
call date, in which case this call date will be deemed to be the maturity date;
or (b) the Bonds are subject to a "mandatory tender", in which case the
mandatory tender will be deemed to be the maturity date. The sales charges in
the above table are expressed as a percentage of the aggregate bid prices of the
Bonds. Expressed as a percent of the Public Offering Price, the sales charge on
a Trust consisting entirely of Bonds with 15 years to maturity would be 4.80%.
The sales charges in the table above do not apply to IM-IT Discount Trusts. The
applicable secondary market sales charges for an IM-IT Discount Trust are set
forth in the applicable Prospectus Part I.
         Any reduced sales charge is the responsibility of the selling
Underwriter, broker, dealer or agent. The Sponsor will, however, increase the
concession or agency commission for quantity purchases. The reduced sales charge
structure in the initial offering period sales charge table above will apply on
all purchases by the same person from any one Underwriter or dealer of units of
Van Kampen American Capital-sponsored unit investment trusts which are being
offered in the initial offering period (a) on any one day (the "Initial Purchase
Date") or (b) on any day subsequent to the Initial Purchase Date, if (1) the
units purchased are of a unit investment trust purchased on the Initial Purchase
Date, and (2) the person purchasing the units purchased a sufficient amount of
units on the Initial Purchase Date to qualify for a reduced sales charge on such
date. In the event units of more than one trust are purchased on the Initial
Purchase Date, the aggregate dollar amount of such purchases will be used to
determine whether purchasers are eligible for a reduced sales charge. Such
aggregate dollar amount will be divided by the public offering price per unit
(on the day preceding the date of purchase) of each respective trust purchased
to determine the total number of units which such amount could have purchased of
each individual trust. Purchasers must then consult the applicable trust's
prospectus to determine whether the total number of units which could have been
purchased of a specific trust would have qualified for a reduced sales charge
and, if so qualified, the amount of such reduction. Assuming a purchaser
qualifies for a sales charge reduction or reductions, to determine the
applicable sales charge reduction or reductions it is necessary to accumulate
all purchases made on the Initial Purchase Date and all purchases made in
accordance with (b) above. Units purchased in the name of the spouse of a
purchaser or in the name of a child of such purchaser ("immediate family
members") 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 Units for one
or more trust, estate or fiduciary accounts.
         Employees, officers and directors (including their spouses, children,
grandchildren, parents, grandparents, siblings, mothers-in-law, fathers-in-law,
sons-in-law and daughters-in-law, and trustees, custodians or fiduciaries for
the benefit of such persons (collectively referred to herein as "related
purchasers")) of Van Kampen American Capital Distributors, Inc. and its
affiliates and Underwriters and their affiliates may purchase Units at the
Public Offering Price less the applicable underwriting commission or less the
applicable dealer concession in the absence of an underwriting commission.
Employees, officers and directors (including related purchasers) of dealers and
their affiliates and vendors providing services to the Sponsor may purchase
Units at the Public Offering Price less the applicable dealer concession.
         Purchasers of units of any two consecutive series of a Trust may
aggregate purchases of units of such series for purposes of the sales charge
reduction for quantity purchases, provided that at the time of the initial
purchase of units such purchaser submitted a purchase order for at least 100
units that was partially unfulfilled due to a lack of units of such Trust series
available for sale at such time. The sales charge reduction shall be applied to
the subsequent purchase of units such that the aggregate sales charge reduction
applicable to both purchases will equal the amount described in the initial
offering period sales charge table above.
         Units may be purchased in the primary or secondary market at the Public
Offering Price (for purchases which do not qualify for a sales charge reduction
for quantity purchases) less the concession the Sponsor typically allows to
brokers and dealers for purchases by (1) investors who purchase Units through
registered investment advisers, certified financial planners and registered
broker-dealers who in each case either charge periodic fees for financial
planning, investment advisory or asset management services, or provide such
services in connection with the establishment of an investment account for which
a comprehensive "wrap fee" charge is imposed, (2) bank trust departments
investing funds over which they exercise exclusive discretionary investment
authority and that are held in a fiduciary, agency, custodial or similar
capacity, (3) any person who for at least 90 days, has been an officer, director
or bona fide employee of any firm offering Units for sale to investors or their
immediate family members (as described above) and (4) officers and directors of
bank holding companies that make Units available directly or through
subsidiaries or bank affiliates. Notwithstanding anything to the contrary in
this Prospectus, such investors, bank trust departments, firm employees and bank
holding company officers and directors who purchase Units through this program
will not receive sales charge reductions for quantity purchases.
<PAGE>
         OFFERING PRICE. The Public Offering Price of Units will vary from the
amounts stated under "Summary of Essential Financial Information" in Prospectus
Part I in accordance with fluctuations in the prices of the Bonds. The price of
Units on the Date of Deposit was determined by adding the applicable sales
charge to the aggregate offering price of the Bonds and dividing the sum by the
number of Units outstanding. This price determination was made on the basis of
an evaluation of the Bonds prepared by Interactive Data Corporation, a firm
regularly engaged in the business of evaluating, quoting or appraising
comparable securities. During the initial offering period, the Evaluator will
value the Bonds as of the Evaluation Time on days the New York Stock Exchange is
open for business and will adjust the Public Offering Price of Units
accordingly. This Public Offering Price will be effective for all orders
received at or prior to the Evaluation Time on each such day. The "Evaluation
Time" is the close of trading on the New York Stock Exchange on each day that
the Exchange is open for trading. 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. The secondary market Public Offering Price per Unit will
be equal to the aggregate bid price of the Bonds plus the applicable secondary
market sales charge and dividing the sum by the number of Units outstanding. For
secondary market purposes, this computation will be made by the Evaluator as of
the Evaluation Time for each day on which any Unit is tendered for redemption
and as necessary. The offering price of Bonds may be expected to average
approximately 0.5%-1% more than the bid price.
         The aggregate price of the Bonds is determined on the basis of bid
prices or offering prices, as is appropriate, (a) on the basis of current market
prices obtained from dealers or brokers who customarily deal in bonds comparable
to those held by the Fund; (b) if these prices are not available, on the basis
of current market prices for comparable bonds; (c) by causing the value of the
Bonds 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 Bonds 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 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 default (the "Defaulted Bonds") the value of any 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 Defaulted Bonds not covered by Permanent
Insurance. In addition, the Evaluator will consider the ability of a Portfolio
Insurer to meet its commitments under any insurance policy, including
commitments to issue Permanent Insurance. No value has been ascribed to
insurance obtained by an Insured Trust, if any, as of the date of this
Prospectus.
         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.
         ACCRUED INTEREST. Accrued interest is an accumulation of unpaid
interest on securities which generally is paid semi-annually, although each
Trust accrues interest daily. Because of this, a Trust always has an amount of
interest earned but not yet collected by the Trustee. For this reason, with
respect to sales settling after the First Settlement Date, the proportionate
share of accrued interest to the settlement date is added to the Public Offering
Price of Units. Unitholders will receive the amount of accrued interest paid on
their Units on the next distribution date. In an effort to reduce the accrued
interest which would have to be paid by Unitholders, the Trustee will advance
the amount of accrued interest to the Sponsor as the Unitholder of record as of
the First Settlement Date. Consequently, the accrued interest added to the
Public Offering Price of Units will include only accrued interest from the First
Settlement Date to the date of settlement, less any distributions from the
Interest Account after the First Settlement Date. Because of the varying
interest payment dates of the Bonds, accrued interest at any point in time will
be greater than the amount of interest actually received by a Trust and
distributed to Unitholders. If a Unitholder sells or redeems all or a portion of
his Units, he will be entitled to receive his proportionate share of the accrued
interest from the purchaser of his Units.
         UNIT DISTRIBUTION. Units will be distributed to the public by
Underwriters, broker-dealers and others at the Public Offering Price, plus
accrued interest. The Sponsor intends to qualify 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 for any single transaction as described in the following table,
provided that the Units are acquired from the Sponsor.

         The increased concession or agency commission is a result of the
discount given to purchasers for quantity purchases. See "Public
Offering--General". In addition to the concessions and agency commissions
described in the table, volume concessions or agency commissions of an
additional $5.00 per Unit of an IM-IT, a U.S. Territorial IM-IT, a Long-Term
State or a National Quality Trust and $2.00 per Unit of all other Trusts will be
given to any broker/dealer or agent (other than Underwriters) who purchases from
the Sponsor at least 250 Units of such Trust during the initial offering period.
These additional concessions will be allowed at the time of purchase, provided,
however, the additional concession applicable to initial purchases totaling less
than 250 Units will be paid retroactively at the end of the initial offering
period. The breakpoint concessions or agency commissions are also applied on a
dollar basis utilizing a breakpoint equivalent of $1,000 per Unit and will be
applied on whichever basis is more favorable to the distributor. The breakpoints
will be adjusted to take into consideration purchase orders stated in dollars
which cannot be completely fulfilled due to the requirement that only whole
Units be issued. Certain commercial banks may be making Units 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. Any discount provided to investors will be borne by the
selling dealer or agent. For secondary market transactions, the concession or
agency commission will amount to 70% of the applicable sales charge. The Sponsor
reserves the right to reject, in whole or in part, any order for the purchase of
Units and to change the amount of the concession or agency commission to dealers
and others from time to time.
         SPONSOR AND UNDERWRITER COMPENSATION. The Underwriters will receive a
gross sales commission equal to the sales charge applicable to the transaction
involved. "Public Offering--General". The Sponsor will receive from the
Underwriters the excess of this gross sales commission over the amounts set
forth in the following table, as of the Date of Deposit. For a list of the
Underwriters that have purchased Units from the Sponsor, see "Underwriting" in
Prospectus Part I.

         A. G. Edwards & Sons, Inc. which acts as a Managing Underwriter of
Units of the various series of the IM-IT or National Quality Trust, will receive
from the Sponsor reimbursement for certain costs and further compensation in the
amount of $5.00 for each Unit of the IM-IT or National Quality Trust it
underwrites. In addition, the Sponsor will receive from the Managing
Underwriters of any National Quality, (who underwrite 15% of the Trust involved
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 individual series of such Trusts will
receive an additional $2.00 per each such Unit. 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 addition, the Sponsor has entered into agreements with
Advest, Inc. ("Advest") and Gruntal & Co., Inc. ("Gruntal") whereby Advest and
Gruntal will receive an additional $2.00 per Unit in connection with a minimum
commitment of 1,500 Units of any New York IM-IT Trust. 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. 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. The
breakpoints listed herein will also be applied on a dollar basis utilizing a
breakpoint equivalent of $1,000 per Unit and will be applied on whichever basis
is more favorable to the Underwriter.
<PAGE>
         In addition, the Sponsor and certain Underwriters will realize a profit
or loss, as a result of the difference between the price paid for the Bonds by
the Sponsor and the cost of the Bonds to a Trust. See "Portfolio" and "Notes to
Portfolio" in Prospectus Part I. Underwriters may also realize profits or losses
with respect to Bonds which were acquired by the Sponsor from underwriting
syndicates of which they were members. The Sponsor has not participated as sole
underwriter or as manager or as a member of the underwriting syndicates from
which the Bonds in the Trusts were acquired. Underwriters may further realize
profit or loss during the initial offering period as a result of possible
fluctuations in the market value of the Bonds 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. In addition to any other benefits Underwriters may realize
from the sale of Units, the Sponsor will share on a pro rata basis among senior
Underwriters (those who underwrite at least 250 Units) 50% of any gain (less
deductions for accrued interest and certain costs) represented by the difference
between the cost of the Bonds to the Sponsor and the evaluation of the Bonds on
the Date of Deposit. The Sponsor and certain of the other Underwriters will also
realize profits or losses in the amount of any difference between the price at
which Units are purchased and the price at which Units are resold in connection
with maintaining a secondary market for Units and will also realize profits or
losses resulting from a redemption of repurchased Units at a price above or
below the purchase price.
         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 such firms may be eligible to win
other nominal awards for certain sales efforts, or under which the Sponsor will
reallow to any such firms 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 firms 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.
         MARKET FOR UNITS. Although not obligated to do so, the Sponsor intends
to, and certain of the other Underwriters may, maintain a market for Units and
offer to purchase Units at prices, subject to change at any time, based upon the
aggregate bid prices of the Bonds plus accrued interest and 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 these prices. If a market is not maintained
and the Unitholder cannot find another purchaser, a Unitholder will be able to
dispose of Units by tendering them to the Trustee for redemption at the
Redemption Price. See "Rights of Unitholders--Redemption of Units". A Unitholder
who wishes to dispose of his Units should inquire of his broker as to current
market prices in order to determine whether there is in any price in excess of
the Redemption Price and, if so, the amount thereof. The Trustee will 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 the Units not later than the day on which the Units would
otherwise have been redeemed by the Trustee.
<PAGE>
RIGHTS OF UNITHOLDERS
- --------------------------------------------------------------------------------

         DISTRIBUTIONS OF INTEREST AND PRINCIPAL. Interest received by a Trust,
pro rated on an annual basis, will be distributed monthly unless a Unitholder
elects to receive semi-annual distributions. The amount and time of the first
distribution is described in Prospectus Part I under "Summary of Essential
Financial Information". The plan of distribution selected by a Unitholder will
remain in effect until changed. Unitholders who purchase Units in the secondary
market will receive distributions in accordance with the election of the prior
owner. Unitholders may change their distribution plan by indicating the change
on a card which may be obtained from the Trustee and return the card to the
Trustee with their certificates and other documentation required by the Trustee.
Certificates should be sent by registered or certified mail to avoid their being
lost or stolen. If the card and certificate are properly presented to the
Trustee, the change will become effective on the first day after the next
semi-annual record date and will remain effective until changed.
         Interest received by a Trust, including that part of the proceeds of
any disposition of Bonds which represents accrued interest, is credited by the
Trustee to the Interest Account. Other receipts are credited to the Principal
Account. 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, interest received will be distributed on
each distribution date to Unitholders of record as of the preceding record date.
All distributions will be net of estimated expenses. Funds in the Principal
Account will be distributed on each semi-annual distribution date to Unitholders
of record as of the preceding semi-annual record date. The Trustee is not
required to pay interest on funds held in the Principal or Interest Account (but
may itself earn interest thereon and therefore benefits from the use of these
funds) nor to make a distribution from the Principal Account unless the amount
available for distribution therein shall equal at least $1.00 per Unit. However,
should the amount available for distribution in the Principal Account equal or
exceed $10.00 per Unit, the Trustee will make a special distribution from the
Principal Account on the next monthly distribution date to Unitholders of record
on the related monthly record date.
         Because interest payments are not received by a Trust at a constant
rate throughout the year, interest distributions may be more or less than the
amount credited to the Interest Account as of the record date. For the purpose
of minimizing fluctuations in interest distributions, the Trustee is authorized
to advance amounts necessary to provide interest distributions of approximately
equal amounts. The Trustee is reimbursed for these advances from funds in the
Interest Account on the next record date. Persons who purchase Units between a
record date and a distribution date will receive their first distribution on the
second distribution date after the purchase, under the applicable plan of
distribution.
         REINVESTMENT OPTION. Unitholders may elect to have distributions on
their Units automatically reinvested in shares of certain Van Kampen American
Capital or Morgan Stanley mutual funds which are registered in the Unitholder's
state of residence (the "Reinvestment Funds"). Each Reinvestment Fund has
investment objectives that differ from those of the Trusts. The prospectus
relating to each Reinvestment Fund describes its investment policies and the
procedures to follow to begin reinvestment. A Unitholder may obtain a prospectus
for the Reinvestment Funds from Van Kampen American Capital Distributors, Inc.
at One Parkview Plaza, Oakbrook Terrace, Illinois 60181.
         After becoming a participant in a reinvestment plan, each Trust
distribution will automatically be applied on the applicable distribution date
to purchase shares of the applicable Reinvestment Fund at a net asset value
computed on such date. Unitholders with an existing Guaranteed Reinvestment
Option (GRO) Program account (whereby a sales charge is imposed on distribution
reinvestments) may transfer their existing account into a new GRO account which
allows purchases of Reinvestment Fund shares at net asset value. Confirmations
of all reinvestments will be mailed to the Unitholder by the Reinvestment Fund.
A participant may elect to terminate his or her reinvestment plan and receive
future distributions in cash by notifying the Trustee in writing at least five
days before the next distribution date. Each Reinvestment Fund, its sponsor and
investment adviser have the right to terminate its reinvestment plan at any
time. Unitholders of New York Trusts who are New York residents may elect to
have distributions reinvested in shares of First Investors New York Insured Tax
Free Fund, Inc. subject to a sales charge of $1.50 per $100 reinvested (paid to
First Investors Management Company, Inc.).
         REDEMPTION OF UNITS. A Unitholder may redeem all or a portion of his
Units by tender to the Trustee, at its Unit Investment Trust Division, 101
Barclay Street, 20th Floor, New York, New York 10286, of the certificates
representing the Units to be redeemed, duly endorsed or accompanied by proper
instruments of transfer with signature guaranteed (or by providing satisfactory
indemnity, such as in connection with lost, stolen or destroyed certificates)
and by payment of applicable governmental charges, if any. Redemption of Units
cannot occur until certificates representing the Units or satisfactory indemnity
have been received by the Trustee. No later than seven calendar days following
satisfactory tender, the Unitholder will receive an amount for each Unit equal
to the Redemption Price per Unit next computed after receipt by the Trustee of
the 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
the Evaluation Time on days of trading on the New York Stock Exchange, the date
of tender is the next day on which that Exchange is open and the Units will be
deemed to have been tendered to the Trustee on that day for redemption at the
Redemption Price.
<PAGE>
         Under Internal Revenue Service regulations, the Trustee is required to
withhold a specified percentage of a Unit redemption if the Trustee has not
received the Unitholder's tax identification number as required by such
regulations. Any amount 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, the Unitholder should provide a tax identification number
to the Trustee in order to avoid this possible "back-up withholding".
         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 Bonds as
of the Evaluation Time on days of trading on the New York Stock Exchange on the
date any such determination is made. The Evaluator determines the Redemption
Price per Unit on days Units are tendered for redemption. The Redemption Price
per Unit is the pro rata share of each Unit on the basis of (i) the cash on hand
in the Trust or moneys in the process of being collected, (ii) the value of the
Bonds based on the bid prices of the Bonds, except for cases in which the value
of insurance has been included, (iii) accrued interest, less (a) amounts
representing taxes or other governmental charges and (b) the accrued Trust
expenses. The Evaluator may determine the value of the Bonds 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 the Bonds are in default in
payment of principal or interest or in significant risk of 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". Accrued
interest paid on redemption shall be withdrawn from the Interest Account or, if
the balance therein is insufficient, from the Principal Account. All other
amounts will be withdrawn from the Principal Account. Units so redeemed shall be
cancelled.
         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 Bonds
represented by the Units redeemed. The Trustee may sell Bonds to cover
redemptions. When Bonds are sold, the size and diversity of the Trust will be
reduced. Sales may be required at a time when Bonds 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 SEC determines that
trading on that Exchange is restricted or an emergency exists, as a result of
which disposal or evaluation of the Bonds is not reasonably practicable, or for
other periods as the SEC may by order permit. Under certain extreme
circumstances the Sponsor may apply to the SEC for an order permitting a full or
partial suspension of the right of Unitholders to redeem their Units.
         CERTIFICATES. Ownership of Units is evidenced by certificates unless a
Unitholder makes a written request to the Trustee that ownership be in book
entry form. Units are transferable by making a written request to the Trustee
and, in the case of Units in certificate form, by presentation and surrender of
the certificate to the Trustee properly endorsed or accompanied by a written
instrument or instruments of transfer. A Unitholder must sign the written
request, or certificate transfer instrument, exactly as his name appears on the
records of the Trustee and on the face of any certificate with the signature
guaranteed by a participant in the Securities Transfer Agents Medallion Program
("STAMP") or a signature guaranty program accepted by the Trustee. 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, the Trustee may
require a Unitholder to pay a reasonable fee for each certificate re-issued or
transferred and to pay any governmental charge that may be imposed in connection
with each 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.
         REPORTS PROVIDED. Unitholders will receive a statement of interest and
other receipts received for each distribution. For as long as the Sponsor deems
it to be in the best interest of Unitholders, the accounts of each Trust will be
audited annually by independent certified public accountants and the report of
the accountants will be furnished to Unitholders upon request. Within a
reasonable period of time after the end of each year, the Trustee will furnish
to each person who was a registered Unitholder during that year a statement
describing the interest and principal received on the Bonds, actual Trust
distributions, Trust expenses, a list of the Bonds and other Trust information.
Unitholders will be furnished the Evaluator's evaluations of the Bonds upon
request.

INSURANCE ON THE BONDS IN THE INSURED TRUSTS
- --------------------------------------------------------------------------------

         Insurance has been obtained guaranteeing prompt payment of interest and
principal, when due, in respect of the Bonds in each Insured Trust. An insurance
policy obtained by an Insured Trust, if any, is non-cancellable and will
continue in force so long as the Trust is in existence, the respective Portfolio
Insurer is still in business and the Bonds described in the policy continue to
be held by the Trust. Any portfolio insurance premium for an Insured Trust is
paid by the Trust on a monthly basis. The premium for any Preinsured Bond
insurance has been paid by the issuer, by a prior owner of the Bonds or the
Sponsor and any policy is non-cancellable and will continue in force so long as
the Bonds so insured are outstanding and the Preinsured Bond Insurer remains in
business. The Portfolio Insurers and the Preinsured Bond Insurers are described
in "Portfolio" and the notes thereto in Prospectus Part I. The Portfolio
Insurers are either AMBAC Assurance Corporation or Financial Guaranty Insurance
Company. More detailed information regarding insurance on the Bonds and the
Preinsured Bond and Portfolio Insurers is included in the Information
Supplement. See "Additional Information".
         The portfolio insurance obtained by an Insured Trust, if any,
guarantees the timely payment of principal and interest on the Bonds when they
fall due. For this purpose, "when due" generally means the stated payment or
maturity date for the payment of principal and interest. However, in the event
(a) an issuer defaults in the payment of principal or interest, (b) an issuer
enters into a bankruptcy proceeding or (c) the maturity of the Bond is
accelerated, the affected Portfolio Insurer has the option to pay the
outstanding principal amount of the Bond plus accrued interest to the date of
payment and thereby retire the Bond from the Trust prior to the Bond's stated
maturity date. The insurance does not guarantee the market value of the Bonds or
the value of the Units. The Trustee, upon the sale of a Bond covered under a
portfolio insurance policy has the right to obtain permanent insurance with
respect to the Bond (i.e., insurance to maturity of the Bond regardless of the
identity of the holder) (the "Permanent Insurance") upon the payment of a single
predetermined insurance premium and expenses from the proceeds of the sale of
the Bond. It is expected that the Trustee would exercise the right to obtain
Permanent Insurance only if upon exercise the Trust would receive net proceeds
in excess of the sale proceeds if the Bonds were sold on an uninsured basis.
         The following summary information relating to the listed insurance
companies has been obtained from publicly available information:

         Because the Bonds are insured by Portfolio Insurers or Preinsured Bond
Insurers as to the timely payment of principal and interest, when due, and on
the basis of the various reinsurance agreements in effect, Standard & Poor's has
assigned to the Units of each Insured Trust its "AAA" investment rating. This
rating will be in effect for a period of thirteen months from the Date of
Deposit and will, unless renewed, terminate at the end of such period. See
"Description of Ratings" in the Information Supplement. This rating should not
be construed as an approval of the offering of the Units by Standard & Poor's or
as a guarantee of the market value of the Trust or of the Units.
         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. 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
insurance. The information relating to each Portfolio Insurer has been furnished
by such companies. The financial information with respect to each Portfolio
Insurer appears in reports filed with state insurance regulatory authorities and
is subject to audit and review by such authorities. No representation is made
herein as to the accuracy or adequacy of such information or as to the absence
of material adverse changes in such information subsequent to the dates thereof.

FUND ADMINISTRATION
- --------------------------------------------------------------------------------

         SPONSOR. Van Kampen American Capital Distributors, Inc., a Delaware 
corporation, is the Sponsor of the Trust. The Sponsor is an indirect subsidiary
of VK/AC Holding, Inc. VK/AC Holding, Inc. is a wholly owned subsidiary of MSAM
Holdings II, Inc., which in turn is a wholly owned subsidiary of Morgan Stanley,
Dean Witter, Discover & Co. ("MSDWD").
         MSDWD is a global financial services firm with a market capitalization
of more than $21 billion, which was created by the merger of Morgan Stanley
Group Inc. with Dean Witter, Discover & Co. on May 31, 1997. MSDWD, together
with various of its directly and indirectly owned subsidiaries, is engaged in a
wide range of financial services through three primary businesses: securities,
asset management and credit services. These principal businesses include
securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; asset management; trading of futures,
options, foreign exchange commodities and swaps (involving foreign exchange,
commodities, indices and interest rates); real estate advice, financing and
investing; global custody, securities clearance services and securities lending;
and credit card services. As of June 2, 1997, MSDWD, together with its
affiliated investment advisory companies, had approximately $270 billion of
assets under management, supervision or fiduciary advice.
         Van Kampen American Capital Distributors, Inc. specializes in the
underwriting and distribution of unit investment trusts and mutual funds with
roots in money management dating back to 1926. The Sponsor is a member of the
National Association of Securities Dealers, Inc. and has offices at One Parkview
Plaza, Oakbrook Terrace, Illinois 60181, (630) 684-6000 and 2800 Post Oak
Boulevard, Houston, Texas 77056, (713) 993-0500. It maintains a branch office in
Philadelphia and has regional representatives in Atlanta, Dallas, Los Angeles,
New York, San Francisco, Seattle and Tampa. As of November 30, 1996, the total
stockholders' equity of Van Kampen American Capital Distributors, Inc. was
$129,451,000 (unaudited). (This paragraph relates only to the Sponsor and not to
the Fund or to any other Series thereof. The information is included herein only
for the purpose of informing investors as to the financial responsibility of the
Sponsor and its ability to carry out its contractual obligations. More detailed
financial information will be made available by the Sponsor upon request.)
         As of March 31, 1997, the Sponsor and its Van Kampen American Capital
affiliates managed or supervised approximately $58.45 billion of investment
products, of which over $10.85 billion is invested in municipal bonds. The
Sponsor and its Van Kampen American Capital affiliates managed $47 billion of
assets, consisting of $29.23 billion for 59 open-end mutual funds (of which 46
are distributed by Van Kampen American Capital Distributors, Inc.) $13.4 billion
for 37 closed-end funds and $4.97 billion for 106 institutional accounts. The
Sponsor has also deposited approximately $26 billion of unit investment trusts.
All of Van Kampen American Capital's open-end funds, closed-ended funds and unit
investment trusts are professionally distributed by leading financial firms
nationwide. Based on cumulative assets deposited, the Sponsor believes that it
is the largest sponsor of insured municipal unit investment trusts, primarily
through the success of its Insured Municipals Income Trust(R) or the IM-IT(R)
trust. The Sponsor also provides surveillance and evaluation services at cost
for approximately $13 billion of unit investment trust assets outstanding. Since
1976, the Sponsor has serviced over two million investor accounts, opened
through retail distribution firms.
         If the Sponsor shall fail to perform any of its duties under the Trust
Agreement or become incapable of acting or become bankrupt or its affairs are
taken over by public authorities, then the Trustee may (i) appoint a successor
Sponsor at rates of compensation deemed by the Trustee to be reasonable and not
exceeding amounts prescribed by the SEC, (ii) terminate the Trust Agreement and
liquidate the Fund as provided therein or (iii) continue to act as Trustee
without terminating the Trust Agreement.
         TRUSTEE. The Trustee is The Bank of New York, a trust company organized
under the laws of New York. The Bank of New York has its unit investment trust
division offices at 101 Barclay Street, New York, New York 10286, telephone
(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. Additional
information regarding the Trustee is set forth in the Information Supplement,
including the Trustee's qualifications and duties, its ability to resign, the
effect of a merger involving the Trustee and the Sponsor's ability to remove and
replace the Trustee. See "Additional Information".
         PORTFOLIO ADMINISTRATION. The Trusts are not managed funds and, except
as provided in the Trust Agreement, Bonds generally will not be sold or
replaced. The Sponsor may, however, direct that Bonds be sold in certain limited
situations to protect to the Trust based on advice from the Evaluator. These
situations may include default in interest or principal payments on the Bonds or
other obligations of an issuer, an advanced refunding or institution of certain
legal proceedings. In addition, the Trustee may sell Bonds designated by the
Evaluator for purposes of redeeming Units or payment of expenses. The Evaluator
will consider a variety of factors in designating Bonds to be sold including
interest rates, market value and marketability. Except in limited circumstances,
the Trustee must reject any offer by an issuer to issue bonds in exchange or
substitution for the Bonds (such as a refunding or refinancing plan). The
Trustee will promptly notify Unitholders of any exchange or substitution. The
Information Supplement contains a more detailed description of circumstances in
which Bonds may be sold or replaced. See "Additional Information".
<PAGE>
         REPLACEMENT BONDS. No assurance can be given that a Trust will retain
its present size or composition because Bonds may be sold, redeemed or mature
from time to time and the proceeds will be distributed to Unitholders and will
not be reinvested. In the event of a failure to deliver any Bond that has been
purchased under a contract ("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 portfolio of a Trust. 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 must
be substantially identical to the Failed Bonds in terms of (i) the exemption
from federal and state taxation, (ii) maturity, (iii) yield to maturity and
current return, (iv) Standard & Poor's or Moody's ratings, and (v) insurance in
an Insured Trust. The Trustee shall notify all Unitholders of a Trust within
five days after the acquisition of a Replacement Bond and shall make a pro rata
distribution of the amount, if any, by which the cost of the Failed Bond
exceeded the cost of the Replacement Bond plus accrued interest. If Failed Bonds
are not replaced, the Sponsor will refund the sales charge attributable to the
Failed Bonds to all Unitholders of the Trust and distribute the principal and
accrued interest (at the coupon rate of the Failed Bonds to the date of removal
from the Trust) attributable to the Failed Bonds within 30 days after removal.
All interest paid to a Unitholder which accrued after the expected date of
settlement for Units will be paid by the Sponsor and accordingly will not be
treated as tax-exempt income. If Failed Bonds are not replaced, the Estimated
Net Annual Interest Income per Unit would be reduced and the Estimated Current
Return and Estimated Long-Term Return might be lowered. Unitholders may not be
able to reinvest their proceeds in other securities at a yield equal to or in
excess of the yield of the Failed Bonds.
         AMENDMENT OF TRUST AGREEMENT. The Sponsor and the Trustee may amend the
Trust Agreement without the consent of Unitholders to correct any provision
which may be defective or to make other provisions that will not adversely
affect the interest of the Unitholders (as determined in good faith by the
Sponsor and the Trustee). The Trust Agreement may not be amended to increase the
number of Units or to permit the acquisition of Bonds in addition to or in
substitution for any of the Bonds initially deposited in the Trust, except for
the substitution of certain refunding Bonds. The Trustee will notify Unitholders
of any amendment.
         TERMINATION OF TRUST AGREEMENT. A Trust will terminate upon the
redemption, sale or other disposition of the last Bond held in the Trust. A
Trust may also be terminated at any time by consent of Unitholders of 51% of the
Units then outstanding or by the Trustee when the value of the Trust is less
than 20% of the original principal amount of Bonds. The Trustee will notify each
Unitholder of any termination within a reasonable time and will then liquidate
any remaining Bonds. The sale of Bonds upon termination may result in a lower
amount than might otherwise be realized if sale were not required at that time.
For this reason, among others, the amount realized by a Unitholder upon
termination may be less than the principal amount of Bonds per Unit or value at
the time of purchase. The Trustee will distribute to each Unitholder his share
of the balance of the Interest and Principal Accounts after deduction of costs,
expenses or indemnities. The Unitholder will receive a final distribution
statement with this distribution. When the Trustee in its sole discretion
determines that any amounts held in reserve are no longer necessary, it will
distribute these amounts to Unitholders. The Information Supplement contains
further information regarding termination of a Trust.
See "Additional Information".
         LIMITATION ON LIABILITIES. The Sponsor, Evaluator and 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 (negligence in the case of the Trustee) 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
Bonds. 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 is not liable
for any taxes or governmental charges imposed on the Bonds, on it as Trustee
under the Trust Agreement or on 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 and Sponsor may rely on any evaluation furnished by the Evaluator and
have no responsibility for the accuracy thereof. Determinations by the Evaluator
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.
<PAGE>
FEDERAL TAX STATUS
- --------------------------------------------------------------------------------

         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 were rendered by bond counsel to the respective issuing authorities. In
addition, with respect to State Trusts, where applicable, bond counsel to the
issuing authorities rendered opinions as to the exemption of interest on such
Bonds when held by residents of the State in which the issuers of such Bonds are
located from state income taxes and certain state or local intangibles and local
income taxes. Neither the Sponsor nor Chapman and Cutler have made any review of
the Trust proceedings relating to the issuance of the Bonds or of the basis of
such opinions. If the interest on a Bond should be determined to be taxable, the
Bond would generally have to be sold at a substantial discount. In addition,
investors could be required to pay income tax on interest received prior to the
date on which interest is determined to be taxable. Gain realized on the sale or
redemption of the Bonds by the Trustee or of a Unit by a Unitholder is
includible in gross income for Federal income tax purposes and may be includible
in gross income for state tax purposes. Such gain does not include any amounts
received in respect of accrued interest or accrued original issue discount, if
any. If a Bond is acquired with accrued interest, that portion of the price paid
for the accrued interest is added to the tax basis of the Bond. When this
accrued interest is received, it is treated as a return of capital and reduces
the tax basis of the Bond. If a Bond is purchased for a premium, the amount of
the premium is added to the tax basis of the Bond. Bond premium is amortized
over the remaining term of the Bond, and the tax basis of the Bond is reduced
each tax year by the amount of the premium amortized in that tax year. For
purposes of the following opinions, it is assumed that each asset of the Trust
is debt, the interest on which is excluded for Federal income tax purposes.
         In the opinion of Chapman and Cutler, counsel for the Sponsor, under
          existing law as of the date of this Prospectus:
   (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 for Federal income tax
        purposes, when received by a Trust and when distributed to Unitholders;
        however such interest may be taken into account in computing the
        alternative minimum tax, an additional tax on branches of foreign 
        corporations and the environmental tax (the "Superfund Tax"), as noted
        below;
   (2)  Each Unitholder is considered to be the owner of a pro rata portion of
        each asset 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.
        If the Unitholder disposes of a Unit, he is deemed thereby to have
        disposed of his entire pro rata interest in all assets of the Trust
        involved including his pro rata portion of all the Bonds represented by
        a Unit. Legislative proposals have been made that would treat certain
        transactions designed to reduce or eliminate risk of loss and
        opportunities for gain as constructive sales for purposes of recognition
        of gain (but not loss). Unitholders should consult their own tax
        advisors with regard to any such constructive sale rules. 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 before the date the Trust acquired
        ownership of the Bonds (and the amount of this reduction may exceed the
        amount of accrued interest paid to the seller) 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 (subject to
        various non-recognition provisions of the Code). 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
        accrued original issue discount and amortized bond premium, if any) is
        determined by apportioning the cost of the Units among each of the Trust
        assets ratably according to value as of the valuation date nearest the
        date of acquisition of the Units. It should be noted that certain
        legislative proposals have been made which could affect the calculation
        of basis for Unitholders holding securities that are substantially
        identical to the Bonds. Unitholders should consult their own tax
        advisors with regard to the calculation of basis. The tax basis
        reduction requirements of the Code relating to amortization of bond
        premium may, under some circumstances, result in the Unitholder
        realizing a taxable gain when his Units are sold or redeemed for an
        amount less than or equal to his original cost;
   (3)  Any proceeds paid under an insurance policy or policies dated the Date
        of Deposit, issued to an Insured Trust 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 in the normal
        course by the issuer of the defaulted obligations provided that, at the
        time such policies are purchased, the amounts paid for such policies are
        reasonable, customary and consistent with the reasonable expectation
        that the issuer of the obligations, rather than the insurer, will pay
        debt service on the obligations; and
<PAGE>
   (4)  Any proceeds paid under individual policies obtained by issuers of Bonds
        which represent maturing interest on defaulted Bonds 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 Bonds provided that, at the time
        such policies are purchased, the amounts paid for such policies are
        reasonable, customary and consistent with the reasonable expectation
        that the issuer of the Bonds, rather than the insurer, will pay debt
        service on the Bonds.
         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. If a Bond is acquired with accrued interest, that
portion of the price paid for the accrued interest is added to the tax basis of
the Bond. When this accrued interest is received, it is treated as a return of
capital and reduces the tax basis of the Bond. If a Bond is purchased for a
premium, the amount of the premium is added to the tax basis of the Bond. Bond
premium is amortized over the remaining term of the Bond, and the tax basis of
the Bond is reduced each tax year by the amount of the premium amortized in that
tax year. The application of these rules will also vary depending on the value
of the Bond on the date a Unitholder acquires his Units and the price the
Unitholder pays for his Units. Unitholders should consult with their tax
advisers regarding these rules and their application.
         "The Revenue Reconciliation Act of 1993" (the "Tax Act") subjects
tax-exempt bonds to the market discount rules of the Code effective for bonds
purchased after April 30, 1993. In general, market discount is the amount (if
any) by which the stated redemption price at maturity exceeds an investor's
purchase price (except to the extent that such difference, if any, is
attributable to original issue discount not yet accrued), subject to a statutory
de minimis rule. Market discount can arise based on the price a Trust pays for
Bonds or the price a Unitholder pays for his or her Units. Under the Tax Act,
accretion of market discount is taxable as ordinary income; under prior law the
accretion had been treated as capital gain. Market discount that accretes while
a Trust holds a Bond would be recognized as ordinary income by the Unitholders
when principal payments are received on the Bond, upon sale or at redemption
(including early redemption), or upon the sale or redemption of his or her
Units, unless a Unitholder elects to include market discount in taxable income
as it accrues. The market discount rules are complex and Unitholders should
consult their tax advisers regarding these rules and their application.
         In the case of certain corporations, the alternative minimum tax and
the Superfund Tax for taxable years beginning after December 31, 1986 depends
upon the corporation's alternative minimum taxable income, which is the
corporation's taxable income with certain adjustments. One of the adjustment
items used in computing the alternative minimum taxable income and the Superfund
Tax of a corporation (other than an S Corporation, Regulated Investment Company,
Real Estate Investment Trust, or REMIC) is an amount equal to 75% of the excess
of such corporation's "adjusted current earnings" over an amount equal to its
alternative minimum taxable income (before such adjustment item and the
alternative tax net operating loss deduction). "Adjusted current earnings"
includes all tax exempt interest, including interest on all of the Bonds in the
Fund. Under current Code provisions, the Superfund Tax does not apply to tax
years beginning on or after January 1, 1996. Legislative proposals have been
introduced which would extend the Superfund Tax. Under the provisions of Section
884 of the Code, a branch profits tax is levied on the "effectively connected
earnings and profits" of certain foreign corporations which include tax-exempt
interest such as interest on the Bonds in the Trust. Unitholders should consult
their tax advisers with respect to the particular tax consequences to them
including the corporate alternative minimum tax, the Superfund Tax and the
branch profits tax imposed by Section 884 of the Code.
         Counsel for the Sponsor has also advised that under Section 265 of the
Code, interest on indebtedness incurred or continued to purchase or carry Units
of a Trust is not deductible for Federal income tax purposes. The Internal
Revenue Service has taken the position that such indebtedness need not be
directly traceable to the purchase or carrying of Units (however, these rules
generally do not apply to interest paid on indebtedness incurred to purchase or
improve a personal residence). Also, under Section 265 of the Code, certain
financial institutions that acquire Units would generally not be able to deduct
any of the interest expense attributable to ownership of such Units. Legislative
proposals have been made that would extend the financial institution rules to
all corporations. Investors with questions regarding these issues should consult
their tax advisers.
         In the case of certain of the Bonds in the Fund, the opinions of bond
counsel indicate that interest on such Bonds received by a "substantial user" of
the facilities being financed with the proceeds of these Bonds, or persons
related thereto, for periods while such Bonds are held by such a user or related
person, will not be excludible from Federal gross income, although interest on
such Bonds received by others would be excludible from Federal gross income.
"Substantial user" and "related person" are defined under the Code and U.S.
Treasury Regulations. Any person who believes that he or she may be a
"substantial user" or a "related person" as so defined should contact his or her
tax adviser.
<PAGE>
         In the opinion of special counsel to the Fund for New York tax matters,
under existing law, the Fund and each Trust are not associations taxable as
corporations and the income of each Trust will be treated as the income of the
Unitholders under the income tax laws of the State and City of New York.
         All statements of law in the Prospectus concerning exclusion from gross
income for Federal, state or other tax purposes are the opinions of counsel and
are to be so construed.
         At the respective times of issuance of the Bonds, opinions relating to
the validity thereof and to the exclusion of interest thereon from Federal gross
income are rendered by bond counsel to the respective issuing authorities.
Neither the Sponsor nor Chapman and Cutler has made any special review for the
Fund of the proceedings relating to the issuance of the Bonds or of the basis
for such opinions.
         In the case of corporations, the alternative tax rate applicable to
long-term capital gains is 35%, effective for long-term capital gains realized
in taxable years beginning on or after January 1, 1993. For taxpayers other than
corporations, net capital gains (which are defined as net long-term capital gain
over net short-term capital loss for a taxable year) 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. For purposes of
computing the alternative minimum tax for individuals and corporations and the
Superfund Tax for corporations, interest on certain private activity bonds
(which includes most industrial and housing revenue bonds) issued on or after
August 8, 1996 is included as an item of tax preference. Except as otherwise
noted in Prospectus Part I, the Trusts do not include any such private activity
bonds issued on or after that date.
         Section 86 of the Code provides that 50% of Social Security benefits
are includible in gross income to the extent that the sum of "modified adjusted
gross income" plus 50% of the Social Security benefits received exceeds a "base
amount". The base amount is $25,000 for unmarried taxpayers, $32,000 for married
taxpayers filing a joint return and zero for married taxpayers who do not live
apart at all times during the taxable year and who file separate returns.
Modified adjusted gross income is adjusted gross income determined without
regard to certain otherwise allowable deductions and exclusions from gross
income and by including tax-exempt interest. To the extent that Social Security
benefits are includible in gross income, they will be treated as any other item
of gross income.
         In addition, under the Tax Act, for taxable years beginning after
December 31, 1993, up to 85% of Social Security benefits are includible in gross
income to the extent that the sum of "modified adjusted gross income" plus 50%
of Social Security benefits received exceeds an "adjusted base amount." The
adjusted base amount is $34,000 for unmarried taxpayers, $44,000 for married
taxpayers filing a joint return, and zero for married taxpayers who do not live
apart at all times during the taxable year and who file separate returns.
         Although tax-exempt interest is included in modified adjusted gross
income solely for the purpose of determining what portion, if any, of Social
Security benefits will be included in gross income, no tax-exempt interest,
including that received from a Trust, will be subject to tax. A taxpayer whose
adjusted gross income already exceeds the base amount or the adjusted base
amount must include 50% or 85%, respectively, of his Social Security benefits in
gross income whether or not he receives any tax-exempt interest. A taxpayer
whose modified adjusted gross income (after inclusion of tax-exempt interest)
does not exceed the base amount need not include any Social Security benefits in
gross income.
         Ownership of the Units may result in collateral federal income tax
consequences to certain taxpayers, including, without limitation, corporations
subject to either the environmental tax or the branch profits tax, financial
institutions, certain insurance companies, certain S corporations, individual
recipients of Social Security or Railroad Retirement benefits and taxpayers who
may be deemed to have incurred (or continued) indebtedness to purchase or carry
tax-exempt obligations. Prospective investors should consult their tax advisors
as to the applicability of any collateral consequences.
         For a discussion of the state tax status of income earned on Units of a
Trust and recent changes in Federal tax law, see Prospectus Part I. 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.

EXPENSES
- -------------------------------------------------------------------------------

         The Sponsor will not receive any fees in connection with its activities
relating to the Fund. However, American Portfolio Evaluation Services, a
division of Van Kampen American Capital Investment Advisory Corp., which is an
affiliate of the Sponsor, will receive the annual supervisory fee indicated
under "Summary of Essential Financial Information" in Prospectus Part I for
providing portfolio supervisory services for the Fund. In addition, the
Evaluator will receive the annual evaluation fee indicated under "Summary of
Essential Financial Information" in Prospectus Part I for evaluating each
Trust's portfolio. These fees may exceed the actual costs of providing these
services for a Trust but the total amount received by the Evaluator for
providing these services to all Van Kampen American Capital unit investment
trusts will not exceed the total cost of providing the services in any calendar
year. For its services the Trustee will receive the fee indicated under "Summary
of Essential Financial Information" in Prospectus Part I (which may be reduced
as described therein). Part of the Trustee's compensation for its services is
expected to result from the use of the funds being held in the Principal and
Interest Accounts for future distributions, payment of expenses and redemptions
since these Accounts are non-interest bearing to Unitholders. These fees are
based on the outstanding principal amount of Bonds and Units on the Date of
Deposit for the first year and as of the close of business on January 1 for each
year thereafter.
         Premiums for any portfolio insurance are obligations of each Insured
Trust and are payable monthly by the Trustee on behalf of the Trust. As Bonds in
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. 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 following additional charges are or may be incurred by the Trusts:
(a) fees of the Trustee for extraordinary services, (b) expenses of the Trustee
(including legal and auditing expenses) and of counsel designated by the
Sponsor, (c) various governmental charges, (d) expenses and costs of any action
taken by the Trustee to protect the Trusts and the rights and interests of
Unitholders, (e) indemnification of the Trustee for any loss, liability or
expenses incurred by it in the administration of the Fund without negligence,
bad faith or willful misconduct on its part, (f) any special custodial fees
payable in connection with the sale of any of the Bonds in a Trust, (g)
expenditures incurred in contacting Unitholders upon termination of the Trusts
and (h) costs incurred to reimburse the Trustee for advancing funds to the
Trusts to meet scheduled distributions (which costs may be adjusted periodically
in response to fluctuations in short-term interest rates). The fees and expenses
set forth herein are payable out of the Trusts. When such fees and expenses are
paid by or owing to the Trustee, they are secured by a lien on the portfolio of
the applicable Trust. If the balances in the Interest and Principal Accounts are
insufficient to provide for amounts payable by a Trust, the Trustee has the
power to sell Bonds to pay such amounts.
         On or before the twenty-fifth 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. The Trustee also may withdraw from these 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. 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.

   The Trusts include certain types of bonds described below. Accordingly, an
investment in a Trust should be made with an understanding of the
characteristics of and risks associated with such bonds. The types of bonds
included in each Trust are described on the cover of the related Prospectus Part
I. Neither the Sponsor nor the Trustee shall be liable in any way for any
default, failure or defect in any of the Bonds.
   Certain of the Bonds may be general obligations of a governmental entity that
are backed by the taxing power of such entity. 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.
   Certain of the Bonds 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. 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.
   Certain of the Bonds may be health care revenue bonds. 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.
   Certain of the Bonds may be obligations of public utility issuers, including
those selling wholesale and retail electric power and gas. 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. In addition,
Federal, state and municipal governmental authorities may from time to time
review existing, and impose additional, regulations governing the licensing,
construction and operation of nuclear power plants, which may adversely affect
the ability of the issuers of certain of the Bonds to make payments of principal
and/or interest on such Bonds.
   Certain of the Bonds may be obligations of issuers whose revenues are derived
from the sale of water and/or sewerage services. 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.
   Certain of the Bonds may be industrial revenue bonds ("IRBs"). IRBs have
generally been issued under bond resolutions pursuant to which the revenues and
receipts payable under the arrangements with the operator of a particular
project have been assigned and pledged to purchasers. In some cases, a mortgage
on the underlying project may have been granted as security for the IRBs.
Regardless of the structure, payment of IRBs is solely dependent upon the
creditworthiness of the corporate operator of the project or corporate
guarantor. Corporate operators or guarantors may be affected by many factors
which may have an adverse impact on the credit quality of the particular company
or industry. These include cyclicality of revenues and earnings, regulatory and
environmental restrictions, litigation resulting from accidents or
environmentally-caused illnesses, extensive competition and financial
deterioration resulting from a corporate restructuring pursuant to a leveraged
buy-out, takeover or otherwise. Such a restructuring may result in the operator
of a project becoming highly leveraged which may impact on such operator's
creditworthiness which in turn would have an adverse impact on the rating and/or
market value of such bonds. Further, the possibility of such a restructuring may
have an adverse impact on the market for and consequently the value of such
bonds, even though no actual takeover or other action is ever contemplated or
effected.
   Certain of the Bonds 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. 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.
   Certain of the Bonds 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. General problems relating to
school bonds include litigation contesting the state constitutionality of
financing public education in part from ad valorem taxes, thereby creating a
disparity in educational funds available to schools in wealthy areas and schools
in poor areas. Litigation or legislation on this issue may affect the sources of
funds available for the payment of school bonds in the Trusts. General problems
relating to college and university obligations include the prospect of a
declining percentage of the population consisting of "college" age individuals,
possible inability to raise tuitions and fees sufficiently to cover increased
operating costs, the uncertainty of continued receipt of Federal grants and
state funding, and government legislation or regulations which may adversely
affect the revenues or costs of such issuers.
   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. 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. From time to time the air transport industry has experienced
significant variations in earnings and traffic, due to increased competition,
excess capacity, increased costs, deregulation, traffic constraints and other
factors, and several airlines have experienced severe financial difficulties.
Similarly, payment on bonds related to other facilities is dependent on revenues
from the projects, such as user fees from ports, tolls on turnpikes and bridges
and rents from buildings. Therefore, payment may be adversely affected by
reduction in revenues due to such factors as increased cost of maintenance,
decreased use of a facility, lower cost of alternative modes of transportation,
scarcity of fuel and reduction or loss of rents.
   Certain of the Bonds may be obligations which are payable from and secured by
revenues derived from the operation of resource recovery facilities. 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; and 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 a Trust
prior to the stated maturity of the Bonds.
   Certain of the Bonds may have been acquired at a market discount from par
value at maturity. The coupon interest rates on discount bonds at the time they
were purchased and deposited in a Trust were lower than the current market
interest rates for newly issued bonds of comparable rating and type. If such
interest rates for newly issued comparable bonds increase, the market discount
of previously issued bonds will become greater, and if such interest rates for
newly issued comparable bonds decline, the market discount of previously issued
bonds will be reduced, other things being equal. Investors should also note that
the value of bonds purchased at a market discount will increase in value faster
than bonds purchased at a market premium if interest rates decrease. Conversely,
if interest rates increase, the value of bonds purchased at a market discount
will decrease faster than bonds purchased at a market premium. In addition, if
interest rates rise, the prepayment risk of higher yielding, premium Securities
and the prepayment benefit for lower yielding, discount bonds will be reduced. A
bond purchased at a market discount and held to maturity will have a larger
portion of its total return in the form of taxable income and capital gain and
less in the form of tax-exempt interest income than a comparable bond newly
issued at current market rates. See "Federal Tax Status" in Prospectus Part II.
Market discount attributable to interest changes does not indicate a lack of
market confidence in the issue.
   Certain of the Bonds may be "zero coupon" bonds. Zero coupon bonds are
purchased at a deep discount because the buyer receives only the right to
receive a final payment at the maturity of the bond and does not receive any
periodic interest payments. The effect of owning deep discount bonds which do
not make current interest payments (such as the zero coupon bonds) is that a
fixed yield is earned not only on the original investment but also, in effect,
on all discount earned during the life of such obligation. This implicit
reinvestment of earnings at the same rate eliminates the risk of being unable to
reinvest the income on such obligation at a rate as high as the implicit yield
on the discount obligation, but at the same time eliminates the holder's ability
to reinvest at higher rates in the future. For this reason, zero coupon bonds
are subject to substantially greater price fluctuations during periods of
changing market interest rates than are securities of comparable quality which
pay interest.
   Certain of the Bonds may have been purchased on a "when, as and if issued" or
"delayed delivery" basis. See "Notes to Portfolio" in Prospectus Part I. The
delivery of any such Bonds may be delayed or may not occur. Interest on these
Bonds begins accruing to the benefit of Unitholders on their respective dates of
delivery. To the extent any Bonds are actually delivered to the Fund after their
respective expected dates of delivery, Unitholders who purchase their Units
prior to the date such Bonds 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 Bonds during the interval between their purchase of Units and
the actual delivery of such Bonds. As a result of any such adjustment, the
Estimated Current Returns during the first year would be slightly lower than
those stated in the Prospectus 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 in Prospectus Part I. Unitholders will be "at risk" with respect
to all Bonds in the portfolios including "when, as and if issued" and "delayed
delivery" Bonds (i.e., may derive either gain or loss from fluctuations in the
evaluation of such Bonds) from the date they commit for Units.
   Certain of the Bonds may be subject to redemption prior to their stated
maturity date pursuant to sinking fund provisions, call provisions or
extraordinary optional or mandatory redemption provisions or otherwise. A
sinking fund is a reserve fund accumulated over a period of time for retirement
of debt. A callable debt obligation is one which is subject to redemption or
refunding prior to maturity at the option of the issuer. A refunding is a method
by which a debt obligation is redeemed, at or before maturity, by the proceeds
of a new debt obligation. In general, call provisions are more likely to be
exercised when the offering side valuation is at a premium over par than when it
is at a discount from par. The exercise of redemption or call provisions will
(except to the extent the proceeds of the called bonds are used to pay for Unit
redemptions) result in the distribution of principal and may result in a
reduction in the amount of subsequent interest distributions; it may also affect
the current return on Units of the Trust involved. Each Trust portfolio contains
a listing of the sinking fund and call provisions, if any, with respect to each
of the debt obligations. Extraordinary optional redemptions and mandatory
redemptions result from the happening of certain events. Generally, events that
may permit the extraordinary optional redemption of bonds or may require the
mandatory redemption of bonds include, among others: a final determination that
the interest on the bonds is taxable; the substantial damage or destruction by
fire or other casualty of the project for which the proceeds of the bonds were
used; an exercise by a local, state or Federal governmental unit of its power of
eminent domain to take all or substantially all of the project for which the
proceeds of the bonds were used; changes in the economic availability of raw
materials, operating supplies or facilities or technological or other changes
which render the operation of the project for which the proceeds of the bonds
were used uneconomic; changes in law or an administrative or judicial decree
which renders the performance of the agreement under which the proceeds of the
bonds were made available to finance the project impossible or which creates
unreasonable burdens or which imposes excessive liabilities, such as taxes, not
imposed on the date the bonds are issued on the issuer of the bonds or the user
of the proceeds of the bonds; an administrative or judicial decree which
requires the cessation of a substantial part of the operations of the project
financed with the proceeds of the bonds; an overestimate of the costs of the
project to be financed with the proceeds of the bonds resulting in excess
proceeds of the bonds which may be applied to redeem bonds; or an underestimate
of a source of funds securing the bonds resulting in excess funds which may be
applied to redeem bonds. The issuer of certain bonds in a Trust may have sold or
reserved the right to sell, upon the satisfaction of certain conditions, to
third parties all or any portion of its rights to call bonds in accordance with
the stated redemption provisions of such bonds. In such a case the issuer no
longer has the right to call the bonds for redemption unless it reacquires the
rights from such third party. A third party pursuant to these rights may
exercise the redemption provisions with respect to a bond at a time when the
issuer of the bond might not have called a bond for redemption had it not sold
such rights. The Sponsor is unable to predict all of the circumstances which may
result in such redemption of an issue of Bonds. See also the discussion of
single family mortgage and multi-family revenue bonds above for more information
on the call provisions of such bonds.
   To the best knowledge of the Sponsor, there is no litigation pending as of
the Date of Deposit in respect of any Bonds 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 Bonds 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 Bonds 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 Bond on the date of
issuance to the effect that such Bonds 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 Bonds.

                  INSURANCE ON THE BONDS IN THE INSURED TRUSTS
   Insurance has been obtained by each Insured Trust, by the issuer of Bonds in
an Insured Trust, 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 Settlement of
Bonds in "The Trusts--Objectives and Bond Selection" in Prospectus Part II. The
Portfolio Insurers and the Preinsured Bond Insurers are described under
"Portfolio" and "Notes to Portfolio" in Prospectus Part I. The Portfolio
Insurers are either AMBAC Assurance Corporation or Financial Guaranty Insurance
Company. 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 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 in Prospectus Part I). Any portfolio insurance
premium for an Insured Trust, which is an obligation of such Trust, is paid by
such 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 when they
fall due. For the purposes of insurance obtained by an Insured Trust, "when due"
generally means the stated payment or maturity date for the payment of principal
and interest. However, in the event (a) an issuer of a Bond defaults in the
payment of principal or interest on such Bond, (b) such issuer enters into a
bankruptcy proceeding or (c) the maturity of such Bond is accelerated, the
affected Portfolio Insurer has the option, in its sole discretion, after
receiving notice of the earliest to occur of such a default, bankruptcy
proceeding or acceleration to pay the outstanding principal amount of such Bond
plus accrued interest to the date of such payment and thereby retire the Bond
from the affected Trust prior to such Bond's stated maturity date. The insurance
does not guarantee the market value of the Bonds or the value of the Units.
Insurance obtained by an Insured Trust, if any, is only effective as to Bonds
owned by and held in such Trust. In the event of a sale of any such Bond by the
Trustee, such insurance terminates as to such Bond on the date of sale.
   Pursuant to an irrevocable commitment of the Portfolio Insurers, the Trustee,
upon the sale of a Bond covered under a portfolio insurance policy obtained by
an Insured Trust, has the right to obtain permanent insurance with respect to
such Bond (i.e., insurance to maturity of the Bond 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" in Prospectus Part II. 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 "Rights of Unitholders--Redemption of Units" in Prospectus Part II)
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 Securities until their respective maturities in order to
realize the benefits of such Trust's portfolio insurance (see "Fund
Administration--Termination of Trust Agreement" in Prospectus Part II).
   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" in Prospectus Part
II. 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" in Prospectus Part II 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 "The
Trusts--Objectives and Bond Selection" in Prospectus Part II.

Standard & Poor's rates all new issues insured by MBIA "AAA" Prime Grade.
Moody's, Standard & Poor's and Fitch IBCA, Inc. (formerly Fitch Investors
Service, L.P.), all rate the claims paying ability of MBIA as "Triple A."
Moody's and Standard & Poor's rate the claims paying ability of CapMAC "Triple
A."
    The Moody's Investors Service, Inc. rating of MBIA should be evaluated
independently of the Standard & Poor's rating of MBIA. No application has been
made to any other rating agency in order to obtain additional ratings on the
Obligations. 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
Obligations 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 Obligations.

Financial Security or its subsidiaries or to make any additional contribution to
the capital of Financial Security or its subsidiaries. As of September 30, 1997,
the total policyholders' surplus and contingency reserves and the total unearned
premium reserve, respectively, of Financial Security and its consolidated
subsidiaries were, in accordance with statutory accounting principles,
approximately $788,108,000 (unaudited) and $461,203,000 (unaudited), and the
total shareholders' equity and the total unearned premium reserve, respectively,
of Financial Security and its consolidated subsidiaries were, in accordance with
generally accepted accounting principles, approximately $894,461,000 (unaudited)
and $401,251,000 (unaudited). Copies of Financial Security's financial
statements may be obtained by writing to Financial Security at 350 Park Avenue,

    Pursuant to an intercompany agreement, liabilities on financial guaranty
insurance written or reinsured from third parties by Financial Security or any
of its domestic operating insurance company subsidiaries (including FSA
Maryland) 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 and FSA Maryland reinsure a portion of their liabilities under certain
of their financial guaranty insurance policies with other reinsurers under
various quota share treaties and on a transaction-by-transaction basis. Such
reinsurance is utilized as a risk management device and to comply with certain
statutory and rating agency requirements; it does not alter or limit the
obligations of Financial Security or FSA Maryland under any financial guaranty
insurance policy.
    The claims-paying ability of Financial Security and FSA Maryland is rated
"Aaa" by Moody's Investors Service, Inc., and "AAA" by Standard & Poor's Ratings
Services, Nippon Investors Service Inc. and Standard & Poor's (Australia) Pty.
Ltd. Such ratings reflect only the views of the respective rating agencies, are
not recommendations to buy, sell or hold securities and are subject to revision
or withdrawal at any time by such rating agencies.
    Capital Guaranty Insurance Company was involved in a merger in 1995. On
December 20, 1995, Capital Guaranty Corporation ("CGC") merged with a subsidiary
of Financial Security Assurance Holdings Ltd. and Capital Guaranty Insurance
Company, CGC's principal operating subsidiary, changed its name to Financial
Security Assurance of Maryland Inc. ("FSA Maryland") and became a wholly owned
subsidiary of Financial Security Assurance Inc. For further description, see
"Financial Security Assurance Inc." herein.
    The address of FSA Maryland and its telephone number are Steuart Tower, One
Market Plaza, San Francisco, CA 94105-1413 and (415) 995-8000. 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 and the Portfolio
Insurers 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 and the Portfolio Insurers are more restrictive than those of the
Sponsor, the previously stated Trust investment criteria have been limited with
respect to the Bonds. This decision is made prior to the Date of Deposit, as
debt obligations not eligible for insurance are not deposited in an Insured
Trust. Thus, all of the Bonds in the portfolios of the Insured Trusts in the
Fund are insured either by the respective Trust or by the issuer of the Bonds,
by a prior owner of such Bonds or by the Sponsor prior to the deposit of such
Bonds in a Trust.
   Because the Bonds are insured by one of the Portfolio Insurers or one of the
Preinsured Bond Insurers as to the timely payment of principal and interest,
when due, and on the basis of the various reinsurance agreements in effect,
Standard & Poor's has assigned to the Units of each Insured Trust its "AAA"
investment rating. Such rating will be in effect for a period of thirteen months
from the Date of Deposit and will, unless renewed, terminate at the end of such
period. See "Description of Ratings". The obtaining of this rating by an Insured
Trust should not be construed as an approval of the offering of the Units by
Standard & Poor's or as a guarantee of the market value of such Trust or of the
Units.
   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
Bonds in such portfolio had Standard & Poor's "AAA" rating and yet at the same
time to have the protection of insurance of prompt payment of interest and
principal, when due, on the Bonds. There is, of course, no certainty that this
result will be achieved. Preinsured Bonds in an Insured Trust (all of which are
rated "AAA" by Standard & Poor's) may or may not have a higher yield than
uninsured bonds rated "AAA" by Standard & Poor's. In selecting such Bonds for an
Insured Trust, the Sponsor has applied the criteria hereinbefore described.
   In the event of nonpayment of interest or principal, when due, in respect of
a Bond, AMBAC Indemnity shall make such payment not later than 30 days and
Financial Guaranty shall make such payment within one business day after the
respective insurer has been notified that such nonpayment has occurred or is
threatened (but not earlier than the date such payment is due). The insurer, as
regards any payment it may make, will succeed to the rights of the Trustee in
respect thereof. All policies issued by the Portfolio Insurers and the
Preinsured Bond Insurers are substantially identical insofar as obligations to
an Insured Trust are concerned.
   The Internal Revenue Service has issued a letter ruling which holds in effect
that insurance proceeds representing maturing interest on defaulted municipal
obligations paid to holders of insured bonds, under policy provisions
substantially identical to the policies described herein, will be excludable
from Federal gross income under Section 103(a)(1) of the Internal Revenue Code
to the same extent as if such payments were made by the issuer of the municipal
obligations. Holders of Units in an Insured Trust should discuss with their tax
advisers the degree of reliance which they may place on this letter ruling.
However, Chapman and Cutler, counsel for the Sponsor, has given an opinion to
the effect such payment of proceeds would be excludable from Federal gross
income to the extent described under "Federal Tax Status" in Prospectus Part II.
   Each Portfolio Insurer is subject to regulation by the department of
insurance in the state in which it is qualified to do business. Such regulation,
however, is no guarantee that each Portfolio Insurer will be able to perform on
its contract of insurance in the event a claim should be made thereunder at some
time in the future. At the date hereof, it is reported that no claims have been
submitted or are expected to be submitted to any of the Portfolio Insurers which
would materially impair the ability of any such company to meet its commitment
pursuant to any contract of bond or portfolio insurance.
   The information relating to each Portfolio Insurer has been furnished by such
companies. The financial information with respect to each Portfolio Insurer
appears in reports filed with state insurance regulatory authorities and is
subject to audit and review by such authorities. No representation is made
herein as to the accuracy or adequacy of such information or as to the absence
of material adverse changes in such information subsequent to the dates thereof.

                            PORTFOLIO ADMINISTRATION
   The Trustee is empowered to sell, for the purpose of redeeming Units tendered
by any Unitholder, and for the payment of expenses for which funds may not be
available, such of the Bonds designated by the Evaluator as the Trustee in its
sole discretion may deem necessary. The Evaluator, in designating such Bonds,
will consider a variety of factors including (a) interest rates, (b) market
value and (c) marketability. The Sponsor, in connection with the Quality Trusts,
may direct the Trustee to dispose of Bonds 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 or 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 Bonds 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 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 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 "Rights of
Unitholders--Redemption of Units" in Prospectus Part II. The Sponsor is
empowered, but not obligated, to direct the Trustee to dispose of Bonds in the
event of an advanced refunding.
   The Sponsor is required to instruct the Trustee to reject any offer made by
an issuer of any of the Bonds to issue new obligations in exchange or
substitution for any Bond pursuant to a refunding or refinancing plan, except
that the Sponsor may instruct the Trustee to accept or reject such an offer or
to take any other action with respect thereto as the Sponsor may deem proper if
(1) the issuer is in default with respect to such Bond or (2) in the written
opinion of the Sponsor the issuer will probably default with respect to such
Bond in the reasonably foreseeable future. Any obligation so received in
exchange or substitution will be held by the Trustee subject to the terms and
conditions of the Trust Agreement to the same extent as Bonds originally
deposited thereunder. Within five days after the deposit of obligations in
exchange or substitution for underlying Bonds, the Trustee is required to give
notice thereof to each Unitholder of the Trust thereby affected, identifying the
Bonds eliminated and the Bonds substituted therefor. Except as stated herein and
under "Fund Administration--Replacement Bonds" in Prospectus Part II regarding
the substitution of Replacement Bonds for Failed Bonds, the acquisition by the
Fund of any securities other than the Bonds initially deposited is not
permitted.
   If any default in the payment of principal or interest on any Bonds 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 Bonds within 30 days after notification by the
Trustee to the Sponsor of such default, the Trustee may in its discretion sell
the defaulted Bond and not be liable for any depreciation or loss thereby
incurred.

                               TRUSTEE INFORMATION
   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 unit investment trust division offices
at 101 Barclay Street, New York, New York 10286, telephone (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. 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 Bonds 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.

                       TERMINATION OF THE TRUST AGREEMENT
   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 20% of the original
principal amount of Bonds. 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
Bond 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 Discount, a U.S. Territorial IM-IT, a Long-Term State or a National
Quality Trust, or beyond the end of the year preceding the twentieth anniversary
of the Trust Agreement in the case of IM-IT Limited Maturity, IM-IT
Intermediate, State Intermediate Laddered Maturity and IM-IT Short Intermediate
Trusts. In the event of termination of 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 Bond 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 government
charges. The sale of Bonds 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 Bonds
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 have deteriorated market prices resulting from
a significant risk of default. Since the Preinsured Bonds will reflect the value
of the related insurance, it is the present intention of the Sponsor not to
direct the Trustee to hold any of such Preinsured Bonds after the date of
termination. All proceeds received, less applicable expenses, from insurance on
defaulted Bonds not disposed of at the date of termination will ultimately be
distributed to Unitholders of record as of such date of termination as soon as
practicable after the date such defaulted Bond or Bonds become due and
applicable insurance proceeds have been received by the Trustee.

                             DESCRIPTION OF RATINGS
   STANDARD & POOR'S, A DIVISION OF THE MCGRAW-HILL COMPANIES. A Standard &
Poor's 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 rating symbols and their meanings follows:
   Aaa--Bonds which are rated Aaa are judged to be the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge". Interest payments are protected by a large, or by an exceptionally
stable, margin and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues. With the occasional
exception of oversupply in a few specific instances, the safety of obligations
of this class is so absolute that their market value is affected solely by money
market fluctuations.
   Aa--Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuations of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in Aaa
securities. These Aa bonds are high grade, their market value virtually immune
to all but money market influences, with the occasional exception of oversupply
in a few specific instances.
   A--Bonds which are rated A possess many favorable investment attributes and
are to be considered as higher medium grade obligations. Factors giving security
to principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future. The market
value of A-rated bonds may be influenced to some degree by credit circumstances
during a sustained period of depressed business conditions. During periods of
normalcy, bonds of this quality frequently move in parallel with Aaa and Aa
obligations, with the occasional exception of oversupply in a few specific
instances.
   Baa--Bonds which are rated Baa are considered as medium grade obligations;
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
   Moody's bond rating symbols may contain numerical modifiers of a generic
rating classification. The modifier 1 indicates that the bond ranks at the high
end of its category; the modifier 2 indicates a mid-range ranking; and the
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
   Con--Bonds for which the security depends upon the completion of some act or
the fulfillment of some condition are rated conditionally. These are bonds
secured by (a) earnings of projects under construction, (b) earnings of projects
unseasoned in operating experience, (c) rentals which begin when facilities are
completed, or (d) payments to which some other limiting condition attaches.
Parenthetical rating denotes probable credit stature upon completion of
construction or elimination of basis of condition.
               EQUIVALENT TAXABLE ESTIMATED CURRENT RETURN TABLES
   As of the date of the 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 1998. They incorporate increased tax
rates for higher income taxpayers that were included in the Revenue
Reconciliation Act of 1993. These tables illustrate approximately what you would
have to earn on taxable investments to equal the tax-exempt estimated current
return in your income tax bracket. The tables assume that Federal taxable income
is equal to State income subject to tax, and for cases in which more than one
State rate falls within a Federal bracket, the State rate corresponding to the
highest income within that Federal bracket is used. The combined State and
Federal tax rates shown reflect the fact that State tax payments are currently
deductible for Federal tax purposes. The tables do not reflect any local taxes
or any taxes other than personal income taxes. The tables do not show the
approximate taxable estimated current returns for individuals that are subject
to the alternative minimum tax. The taxable equivalent estimated current returns
may be somewhat higher than the equivalent returns indicated in the following
tables for those individuals who have adjusted gross incomes in excess of
$124,500. The tables do not reflect the effect of Federal or State limitations
(if any) on the amount of allowable itemized deductions and the deduction for
personal or dependent exemptions or any other credits. These limitations were
designed to phase out certain benefits of these deductions for higher income
taxpayers. These limitations, in effect, raise the marginal maximum Federal tax
rate to approximately 44 percent for taxpayers filing a joint return and
entitled to four personal exemptions and to approximately 41 percent for
taxpayers filing a single return entitled to only one personal exemption. These
limitations are subject to certain maximums, which depend on the number of
exemptions claimed and the total amount of 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
"Federal Tax Status" in Prospectus Part II for a more detailed discussion of
recent Federal tax legislation.

* The State of Florida does not impose an income tax on individuals. However,
Florida does impose an intangible personal property tax, which is not included
in this table, because it is generally based on property value rather than
income.

   A comparison of tax-free and equivalent taxable estimated current returns
with the returns on various taxable investments is one element to consider in
making an investment decision. The Sponsor may from time to time in its
advertising and sales materials compare the then current estimated returns on
the Trusts and returns over specified periods on other similar Van Kampen
American Capital sponsored unit investment trusts with inflation rates and 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
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 in the Prospectus.
   
                              FLORIDA RISK FACTORS
   Population. Historically, population growth has been a crucial driving force
for Florida's economy. It has accounted for the state's tendency to outperform
the U.S. economy in terms of job creation and total income growth. Between 1980
and 1990, Florida added almost 3.2 million persons, more than any other state
except California. The state's population has accelerated since the fiscal year
1990-91 recession, sparked by improving economies. From 1996-97, Florida ranked
fourth among the fifty states with an estimated population of 14.63 million. By
1999, Florida's population is expected to average 15.18 million. Florida's
attraction, as both a growth and retirement state, has kept net migration fairly
steady. Net migration reached a peak of 229,000 in FY 1993-94. It remained close
to this peak in FY 1994-95 and FY 1995-96. In FY 1996-97, net migration is
estimated to have reached a new peak of 253,000. In FY 1997-98, it is expected
to decline to 242,000. Yet, Florida continues to be the fastest growing of the
eleven largest states. In addition to attracting senior citizens to Florida as a
place for retirement, the State is also recognized as attracting a significant
number of working age individuals. Since 1985, the prime working age population
(18-44) has grown at an average annual rate of 2.2%. The share of Florida's
total working age population (18-59) to total State population is approximately
54%. This share is not expected to change appreciably into the twenty-first
century.
   Income. The State's personal income has been growing strongly the last
several years and has generally outperformed both the United States as a whole
and the southeast in particular, according to the U.S. Department of Commerce
and the Florida Consensus Economic Estimating Conference. This is due to the
fact that Florida's population has been growing at a very strong pace and, since
the early 1970s, the State's economy has diversified so as to provide a broader
economic base. As a result, Florida's real per capita personal income has
tracked closely with the national average and has tracked above the southeast.
Florida's personal income growth is expected to exceed that for the United
States in both FY 1997-98 and 1998-99. Real personal income will increase 3.6%
in FY 1998-99, slower than the 5.1% increase expected for FY 1997-98, and only a
little faster than the 3.2% increase of FY 1996-97. Florida had a per capita
personal income of $24,226 in 1996 and the United States had $24,426. Real per
capita income will slow to a 1.8% growth rate in FY 1998-99 from 3.1% in FY
1997-98.
   Because Florida has a proportionately greater retirement age population,
property income (dividends, interest and rent) and transfer payments (Social
Security and pension benefits, among other sources of income) are relatively
more important sources of income. For example, Florida's total wages and
salaries and other labor income in 1996-97 was 54.2% of total personal income,
while a similar figure for the nation was 62.4%. Property income accounted for
25.6% of total personal income in Florida in 1996-97 and transfer payments made
up 18.7%. Property income and transfer payments for the U.S. were 18.1% and
16.4%, respectively. Transfer payments are typically less sensitive to the
business cycle than employment income and, therefore, act as stabilizing forces
in weak economic periods.
   Employment. Historically, Florida's economy has outperformed the nation's, a
relationship that is expected to continue. Florida has typically created jobs
50% faster than the national rate. Contributing to the State's rapid rate of
growth in employment and income is international trade. Changes to its economy
have also contributed to the State's strong performance. The State is now less
dependent on employment from construction, construction related manufacturing,
and resource based manufacturing, which have declined as a proportion of total
State employment. In recent years, the State's service sector employment has
accounted for approximately 85% of total non-farm employment. While the
southeast and the nation have a greater proportion of manufacturing jobs, which
tend to pay higher wages, service jobs tend to be less sensitive to swings in
the business cycle. The State has a concentration of manufacturing jobs in
high-tech and high value-added sectors, such as electrical and electronic
equipment, as well as printing and publishing. Manufacturing employment is
forecast to decline slightly in FY 1997-98 and FY 1998-99.
   As the State's economic growth has slowed from its previous highs, its
unemployment rate has tracked above the national average. More recently,
Florida's unemployment rate has been below the national average. The State's
unemployment rate was 4.8% in November 1996 and 4.6% in November 1997. The
national unemployment rate was 5.4% in 1996 and 4.6% as of November 1997.
   The State's economy is expected to decelerate along with the nation, but is
expected to outperform the nation as a whole. Florida ranked third nationally
and created more than 217,000 new jobs prior to the end of 1997. Total non-farm
employment in Florida is expected to increase 3.9% in 1997-98 and 2.6% in
1998-99. In comparison, the U.S. growth rate peaked in the first quarter of 1997
at an annual rate of 3.2% but has slowly declined and is estimated to average
1.3% by FY 1998-99.
   The strongest areas in job growth in Florida in fiscal year 1997-98 and
1998-99 are expected to be in services and a combination of retail and wholesale
trade. Services are forecast to lead the economy, growing 4.7% (105,400 jobs) in
fiscal year 1997-98, and accounting for about 50% of total new jobs in that
year. Services are the single largest source of employment in Florida, making up
about a third of the total in fiscal year 1997-98.
   Wholesale and retail trade is projected to increase 3.6% in fiscal year
1997-98 (59,700 new jobs), which parallels general economic growth. This sector
is the second largest, with about 25% of all jobs in the state, and is
anticipated to increase 2.3% (39,100 jobs) in fiscal year 1998-99. Construction
job growth is expected to decline from 12% (42,000 jobs) in FY 1997-98 to 1.5%
(5,600 jobs) in FY 1998-99 because of a slowing economy. Manufacturing will
continue to struggle with the effects of international competition.
   Tourism. Tourism is one of Florida's most important industries. Approximately
41.8 million tourists visited the State in 1995. In terms of business activities
and State tax revenues, tourists in Florida effectively represented additional
residents, spending their dollars predominantly at eating and drinking
establishments, hotels and motels, and amusement and recreation parks. The
State's tourist industry over the years has become more sophisticated,
attracting visitors year-round and, to a degree, reducing its seasonality. By
the end of fiscal year 1997-98, 43.8 million domestic and international tourists
are expected to have visited the State. In 1998-99, tourist arrival should reach
a high of 45.6 million, representing 4.1% growth from 1997-98.
   Revenues and Expenses. Estimated fiscal year 1997-98 General Revenue plus
Working Capital and Budget Stabilization funds available to the State total
$18,150.9 million. Of the total General Revenue plus Working Capital and Budget
Stabilization funds available to the State, $16,598.5 million of that is
Estimated Revenues. With effective General Revenues plus Working Capital Fund
appropriations at $17,201.7 million, unencumbered reserves at the end of 1997-98
are estimated at $949.2 million with $263.2 million of this amount from the
Working Capital Fund. Estimated fiscal year 1998-99 General Revenue plus Working
Capital and Budget Stabilization funds available total $18,546.1 million, a 2.2%
increase over 1997-98. The $17,405.5 million in Estimated Revenues represents an
increase of 4.9% over the previous year's Estimated Revenues. Total estimated
appropriations in the combined General Revenue and Working Capital Fund for
1998-99 are $17,672.4 million, a 5.7% increase from 1997-98.
   In fiscal year 1998-99, approximately 71% of the State's $17,672.4 million
General revenue will come from sales tax collections. Corporate income tax,
intangible personal property tax and beverage tax will account for 8%, 4% and
3%, respectively, of total General Revenue Funds available during fiscal
1998-99. In that same year, expenditures for education, human services and
criminal justice and corrections will amount to approximately 53%, 24% and 16%,
respectively, of total expenditures from the General Revenue Fund.
   The State's sales and use tax (6%) currently accounts for the State's single
largest source of tax receipts. Slightly less than 10% of the State's sales and
use tax is designated for local governments and is distributed to the respective
counties in which collected for use by the counties, and the municipalities
therein. In addition to this distribution, local governments may assess (by
referendum) a 0.5% or a 1.0% discretionary sales surtax within their county.
Proceeds from this local option sales tax are earmarked for funding local
infrastructure programs and acquiring land for public recreation or conservation
or protection of natural resources as provided under applicable Florida law.
Certain charter counties have other additional taxing powers, and
non-consolidated counties with a population in excess of 800,000 may levy a
local option sales tax to fund indigent health care. It alone cannot exceed 0.5%
and when combined with the infrastructure surtax, cannot exceed 1.0%. For the
fiscal year ending June 30, 1999, sales and use tax receipts (exclusive of the
tax on gasoline and special fuels) are expected to total $12.5 billion, an
increase of 6.5% over fiscal year 1997-98.
   The second largest source of State tax receipts is the tax on motor fuels.
However, these revenues are almost entirely dedicated trust funds for specific
purposes and are not included in the State's General Revenue Fund.
   The state's second largest funding source for the General Revenue Fund is the
corporate income tax. All receipts of the corporate income tax are credited to
the General Revenue Fund. For the fiscal year ending June 30, 1999, receipts
from this source are estimated to be $1.4 billion, an increase of 1.5% from
fiscal year 1997-98.
   The State imposes an alcoholic beverage wholesale tax (excise tax) on beer,
wine and liquor. This tax is one of the State's major tax sources, with revenues
estimated at $463.9 million in fiscal year ending June 30, 1999. Alcoholic
beverage tax receipts are expected to increase 1.7% from the previous year's
total. This tax generates 3% of the State's total General Revenue and the
revenues collected from this tax are deposited into the State's General Revenue
Fund.
   The State imposes a documentary stamp tax on deeds and other documents
relating to realty, corporate shares, bonds, certificates of indebtedness,
promissory notes, wage assignments and retail charge accounts. The documentary
stamp tax collections are expected to total $935 million during fiscal year
1998-99, a 3.8% increase from the previous fiscal year. Of this amount, $347.7
million is to be deposited to the General Revenue Fund.
   The State imposes a gross receipts tax on electric, natural and manufactured
gas and telecommunications services. All gross receipts utilities tax
collections are credited to the State's Public Education Capital Outlay and Debt
Service Trust Fund. In fiscal year 1998-99, this tax is estimated at $642.9
million, an increase of 5% over the current fiscal year.
   The State imposes an intangible personal property tax on stocks, bonds,
including bonds secured by liens in Florida real property, notes, governmental
leaseholds and certain other intangibles not secured by a lien on Florida real
property. The annual rate of tax is 2 mils. The State also imposes a
non-recurring 2 mil tax on mortgages and other obligations secured by liens on
Florida real property. The intangible personal property tax provides 4% of the
revenues for the General revenue Fund as well as funding the county revenue
sharing program. In fiscal year 1998-99, total intangible personal property tax
collections are estimated at $1.1 billion, a 2.3% decrease from the prior year
in which growth was 15.1%. Of the tax proceeds, $678.4 million will be
distributed to the General Revenue Fund.
   The State began its own lottery in 1988. State law requires that lottery
revenues be distributed 50.0% to the public in prizes, 38.0% for use in
enhancing education, and the balance, 12.0%, for costs of administering the
lottery. Fiscal year 1994-95 lottery ticket sales totaled $2.3 billion,
providing education with approximately $874 million. In fiscal year 1998-99,
sales are estimated at $2,052 million with $785 million available for education
enhancements.
   Debt-Balanced Budget Requirement. As of June 30, 1996, the state's net
outstanding debt totaled $9.0 billion. Approximately 67% is full faith and
credit bonds while the remaining 33% is comprised of revenue bonds pledging a
specific tax or revenue. The Governor's Recommended Budget for fiscal year
1997-98 includes six bond issues totaling $1.38 billion for construction of
schools, roads, bridges, and prisons, and the purchase of environmentally
sensitive lands.
   The State Constitution and statutes mandate that the State budget, as a
whole, and each separate fund within the State budget, be kept in balance from
currently available revenues each fiscal year. If the Governor or Comptroller
believe a deficit will occur in any State fund, by statute, he must certify his
opinion to the Administrative Commission, which then is authorized to reduce all
State agency budgets and releases by a sufficient amount to prevent a deficit in
any fund. Additionally, the State Constitution prohibits issuance of State
obligations to fund State operations.
   Litigation. Currently under litigation are several issues relating to State
actions or State taxes that put at risk substantial amounts of General Revenue
Fund monies. Accordingly, there is no assurance that any of such matters,
individually or in the aggregate, will not have a material adverse affect on the
State's financial position.
   The State of Florida and the tobacco industry settled a lawsuit on August 25,
1997, in which the state sought to recover the costs associated with tobacco
usage by Florida residents. The settlement provided for $750 million in payments
to the state on or before September 15, 1997, then annual payments beginning
September 15, 1998, that will accumulate to about $10.5 billion over 25 years.
The estimated payment for FY 1998-99 is $220 million.
   Ratings. The State maintains a bond rating of Aa2, AA+ and AA from Moody's
Investors Service, Standard & Poor's and Fitch, respectively, on the all of its
general obligation bonds. While these ratings and some of the information
presented above indicate that the State is in satisfactory economic health,
there can be no assurance that there will not be a decline in economic
conditions or that particular Florida Bonds purchased by the fund will not be
adversely affected by any such changes.
   The sources for the information presented above include official statements
and financial statements of the State of Florida. While the Sponsor has not
independently verified this information, it has no reason to believe that the
information is not correct in all material respects.
                              MICHIGAN RISK FACTORS
   Investors should be aware that the economy of the State of Michigan has, in
the past, proven to be cyclical, due primarily to the fact that the leading
sector of the State's economy is the manufacturing of durable goods. While the
State's efforts to diversify its economy have proven successful, as reflected by
the fact that the share of employment in the State in the durable goods sector
has fallen from 33.1 percent in 1960 to 17.9 percent in 1990 and to 15.2 percent
in 1997, durable goods manufacturing still represents a sizable portion of the
State's economy. As a result, any substantial national economic downturn is
likely to have an adverse effect on the economy of the State and on the revenues
of the State and some of its local governmental units.
   In July 1995, Moody's Investors Service, Inc. raised the State's general
obligation bond rating to "Aa". In January 1998, Standard & Poor's raised its
rating on the State's general obligation bonds to "AA+". In April, 1998, Fitch
IBCA, Inc., raised its rating on the State's general obligation bonds to AA+.
   The State's economy could continue to be affected by changes in the auto
industry, notably consolidation and plant closings resulting from competitive
pressures and over-capacity. Such actions could adversely affect State revenues
and the financial impact on the local units of government in the areas in which
plants are closed could be more severe. In addition, as described in the State's
comprehensive annual financial report on file with the Nationally Recognized
Municipal Securities Information Repositories, the State is party to a number of
lawsuits and legal actions, some of which, if determined adversely to the State,
could have a materially adverse impact on the State's finances.
   In recent years, the State of Michigan has reported its financial results in
accordance with generally accepted accounting principles. For each of the last
five fiscal years, the State ended the fiscal year with its General Fund in
balance after transfers in most of those years from the General Fund to the
Budget Stabilization Fund. The balance in the Budget Stabilization Fund was
$1.15 billion as of September 30, 1997, including a reserve of $572.6 million
for educational expenses described in the next paragraph. In all but one of the
last five fiscal years, the State has borrowed between $500 million and $900
million for cash flow purposes. It borrowed $900 million in each of the 1996,
1997 and 1998 fiscal years.
   In November of 1997, the State Legislature adopted legislation to provide for
the funding of claims of local school districts, some of whom had alleged in a
lawsuit, Durant v. State of Michigan, that the State had, over a period of
years, paid less in school aid than required by the State's Constitution. Under
this legislation, the State paid to school districts which were plaintiffs in
the suit approximately $212 million from the Budget Stabilization Fund on April
15, 1998, and will be required to pay to other school districts from the Budget
Stabilization Fund (i) an additional $32 million per year in the years 1998-99
through 2007-08, and (ii) up to an additional $40 million per year in the years
1998-99 through 2012-13.
   The Michigan Constitution of 1963 limits the amount of total revenues of the
State raised from taxes and certain other sources to a level for each fiscal
year equal to a percentage of the State's personal income for the prior calendar
year. In the event that the State's total revenues exceed the limit by 1 percent
or more, the Michigan Constitution of 1963 requires that the excess be refunded
to taxpayers. In order to comply with this requirement, the State refunded
approximately $113 million through income tax credits for the 1995 calendar
year.
   On March 15, 1994, Michigan voters approved a school finance reform amendment
to the State's Constitution which, among other things, increased the State sales
tax rate from 4% to 6% and placed a cap on property assessment increases for all
property taxes. Concurrent legislation cut the State's income tax rate from 4.6%
to 4.4%, reduced some property taxes and altered local school funding sources to
a combination of property taxes and state revenues, some of which is provided
from other new or increased State taxes. The legislation also contained other
provisions that alter (and, in some cases, may reduce) the revenues of local
units of government, and tax increment bonds could be particularly affected.
While the ultimate impact of the constitutional amendment and related
legislation cannot yet be accurately predicted, investors should be alert to the
potential effect of such measures upon the operations and revenues of Michigan
local units of government.
   In addition, the State Legislature in 1995 recently adopted a package of
state tax cuts, including a phase out of the intangibles tax, an increase in
exemption amounts for personal income tax, and reductions in single business
tax.
   Although all or most of the Bonds in the Michigan IM-IT Trust are revenue
obligations or general obligations of local governments or authorities rather
than general obligations of the State of Michigan itself, there can be no
assurance that any financial difficulties the State may experience will not
adversely affect the market value or marketability of the Bonds or the ability
of the respective obligors to pay interest on or principal of the Bonds,
particularly in view of the dependency of local governments and other
authorities upon State aid and reimbursement programs and, in the case of bonds
issued by the State Building Authority, the dependency of the State Building
Authority on the receipt of rental payments from the State to meet debt service
requirements upon such bonds. In the 1991 fiscal year, the State deferred
certain scheduled cash payments to municipalities, school districts,
universities and community colleges. While such deferrals were made up at
specified later dates, similar future deferrals could have an adverse impact on
the cash position of some local governmental units. Additionally, while total
State revenue sharing payments have increased in each of the last five years,
the State did reduce revenue sharing payments to municipalities below that level
otherwise provided under formulas in each of those years.
   The Michigan IM-IT Trust may contain general obligation bonds of local units
of government pledging the full faith and credit of the local unit which are
payable from the levy of ad valorem taxes on taxable property within the
jurisdiction of the local unit. Such bonds issued prior to December 22, 1978, or
issued after December 22, 1978 with the approval of the electors of the local
unit, are payable from property taxes levied without limitation as to rate or
amount. With respect to bonds issued after December 22, 1978, and which were not
approved by the electors of the local unit, the tax levy of the local unit for
debt service purposes is subject to constitutional, statutory and charter tax
rate limitations. In addition, several major industrial corporations have
instituted challenges of their ad valorem property tax assessments in a number
of local municipal units in the State. If successful, such challenges could have
an adverse impact on the ad valorem tax bases of such units which could
adversely affect their ability to raise funds for operation and debt service
requirements.
                           NORTH CAROLINA RISK FACTORS
      See "Portfolio" in Prospectus Part I for a list of the Bonds included in
the North Carolina 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 Bonds. None
of the information is relevant to Bonds issued by territories or possessions of
the United States that may be included in the portfolio of the North Carolina
Trust.
      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. In
addition, the Trust is concentrated on Bonds of North Carolina issuers and is
subject to additional risk from decreased diversification as well as factors
that may be particular to North Carolina or, in the case of revenue bonds
payable exclusively from private party revenues or from specific state non-tax
revenue, factors that may be particular to the related activity or payment
party.
      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. In November
1996, the voters of the State approved a constitutional amendment giving the
Governor the power to veto certain legislative matters, including budgetary
matters.
      Since 1994, the State has had a budget surplus, in part as a result of new
taxes and fees and spending reductions put into place in the early 1990's. In
addition, the State, like the nation, has experienced economic recovery during
the 1990's.
      The State budget is based upon estimated revenues and a multitude of
existing and assumed State and non-State factors, including State and national
economic conditions, international activity and federal government policies and
legislation. The unreserved General Fund balance at June 30, 1997, the end of
the 1996-97 fiscal year was approximately $292.2 million, and the reserved
balance of the General Fund was approximately $880.8 million.
      In 1995, the North Carolina General Assembly repealed, effective for
taxable years beginning January 1, 1995, the tax levied on various forms of
intangible personal property. The legislature provided specific appropriations
to counties and municipalities from state revenues to replace the revenues those
political subdivisions previously received from intangibles tax revenue. In
addition, in the 1996 session the legislature reduced the corporate income tax
rate from 7.75% to 6.9% (phased in over four years), reduced the food tax from
4% to 3%, and eliminated most privilege license taxes as of January 1, 1997. As
a result of the comprehensive tax reductions, General Fund tax collections for
1995-96 grew by only 1.0% over 1994-95, as opposed to the 6.4% growth that would
have occurred if such measures had not been taken.
      In the 1996-97 Budget prepared by the Office of State Budget and
Management, it was projected that General Fund net revenues would increase 3%
over 1995-96. In fact, actual General Fund net revenues for 1996-97 increased
8.3% over 1995-96. This increase resulted primarily from growth in the North
Carolina economy, which resulted in increased personal and corporate income tax
receipts.
      It is unclear what effect these developments at the State level may have
on the value of the Bonds in the North Carolina Trust.
      Litigation. The following are cases pending in which the State faces the
risk of either a loss of revenue or an unanticipated expenditure. In the opinion
of the Department of State Treasurer, an adverse decision in any of these cases
would not materially adversely affect the State's ability to meet its financial
obligations.
      Leandro, et. al. v. State of North Carolina and State Board of Education
- -- In May, 1994, students and boards of education in five counties in the State
filed suit in state Superior Court requesting a declaration that the public
education system of North Carolina, including its system of funding, violates
the North Carolina Constitution by failing to provide adequate or substantially
equal educational opportunities and denying due process of law, and violates
various statutes relating to public education.
      On July 24, 1997, the North Carolina Supreme Court issued a decision in
the case. The Court upheld the present funding system against the claim that it
unlawfully discriminated against low wealth counties on the basis that the
Constitution does not require substantially equal funding and educational
advantages in all school districts. The Court remanded the case for trial on the
claim for relief based on the Court's conclusion that the Constitution
guarantees every child of the state an opportunity to receive a sound basic
education in North Carolina public schools. Five other counties intervened and
now allege claims for relief on behalf of their students' rights to a sound
basic education on the basis of the high proportion of at-risk students in their
counties' systems. The North Carolina Attorney General's Office believes that
sound legal arguments support the State's position on the outstanding claims.
      Francisco Case -- In August, 1994, a class action lawsuit was filed in
state court against the Superintendent of Public Instruction and the State Board
of Education on behalf of a class of parents and their children who are
characterized as limited English proficient. The complaint alleges that the
State has failed to provide funding for the education of these students and has
failed to supervise local school systems in administering programs for them. The
complaint does not allege an amount in controversy, but asks the Court to order
the defendants to fund a comprehensive program to ensure equal educational
opportunities for children with limited English proficiency. Discovery is
underway, but no trial date has been set. The North Carolina Attorney General's
Office believes that sound legal arguments support the State's position.
      Faulkenbury v. Teachers' and State Employees' Retirement System; Peele v.
Teachers' and State Employees' Retirement System; Woodward v. Local Governmental
Employees' Retirement System -- Plaintiffs are disability retirees who brought
class actions in state court challenging changes in the formula for payment of
disability retirement benefits and claiming impairment of contract rights,
breach of fiduciary duty, violation of other federal constitutional rights, and
violation of state constitutional and statutory rights. The Superior Court
issued an order ruling in favor of plaintiffs. The Order was affirmed by the
North Carolina Supreme Court. A determination of the actual amount of the
State's liability and the payment process is being determined by the parties.
The plaintiffs have submitted documentation to the court asserting that the cost
in damages and higher prospective benefit payments to the plaintiffs and class
members would amount to $407 million. These amounts would be payable from the
funds of the Retirement systems.
      Bailey v. State -- State and local government retirees filed a class
action suit in 1990 as a result of the repeal of the income tax exemptions for
state and local government retirement benefits. The original suit was dismissed
after the North Carolina Supreme Court ruled in 1991 that the plaintiffs had
failed to comply with state law requirements for challenging unconstitutional
taxes and the United States Supreme Court denied review.
      In 1992, many of the same plaintiffs filed a new lawsuit alleging
essentially the same claims, including breach of contract, unconstitutional
impairment of contract rights by the State in taxing benefits that were
allegedly promised to be tax-exempt, and violation of several state
constitutional provisions. Thereafter, taxpayers also filed additional lawsuits
claiming refunds of income taxes paid for tax years through 1996. In May 1995,
the trial court found that the repeal of the tax exemption for state and local
government retirement benefits that were vested before August 1989 was unlawful
and that such benefits remain exempt from income taxation.
      The North Carolina Supreme Court allowed discretionary review, and handed
down its decision on May 8, 1998, upholding the decision of the trial court.
Potential refunds and interest are estimated by the State to be $352.68 million
through December 31, 1997, with respect to refunds, and through June 30, 1998,
with respect to interest. Until this matter is resolved, any additional
potential refunds and interest will continue to accrue. In addition to refunds
and interest, the State will be unable to continue to tax the applicable
retirement benefits, thus reducing future revenue. The case was remanded by the
North Carolina Supreme Court for administration and further orders to carry out
the decision. Under the initial order of the trial judge, the State would offset
its liabilities to improperly taxed retirees by allowing tax credits to eligible
retirees who are decreased, no longer residents of the State, or who have no tax
liability, to be paid in whole to such retirees or their estates.
      At present, no decision has been made by the State as to whether it will
seek review of the North Carolina Supreme Court's decision by the United States
Supreme Court or request the North Carolina Supreme Court to reconsider its
decision. There is no assurance that either of such actions would be successful.
      Patton v. State -- Federal retirees filed a class action suit in Wake
County Superior Court in 1995 seeking monetary relief for taxes paid since 1989.
This case was brought in anticipation of a favorable outcome for the plaintiffs
in the Bailey case. The federal retirees allege that a result in the Bailey case
that exempts State and local retirement benefits from State income taxes would
require a similar exemption for federal retirement benefits under the United
States Supreme Court's 1989 decision in Davis v. Michigan. In Davis, the United
States Supreme Court ruled that a Michigan income tax statute taxed federal
retirement benefits while exempting those paid by state and local governments
violated the constitutional doctrine of intergovernmental tax immunity. At the
time of the Davis decision, North Carolina law contained similar exemptions in
favor of state and local retirees. Those exemptions were repealed prospectively,
beginning with the 1989 tax year, by the act of the General Assembly held
unconstitutional in Bailey. The Patton case was being held in abeyance pending
the outcome in Bailey. Now that Baileyhas been decided, the case is expected to
proceed. Potential refunds and interest are estimated by the State to be $702.36
million through December 31, 1997, with respect to refunds, and through June 30,
1998, with respect to interest. Until this matter is resolved, any additional
potential refunds and interest have continued and will continue to accrue.
      Smith, et. al. v. Offerman and State of North Carolina, et. al. -- This
class action is related to litigation in Fulton Corporation v. Faulkner, 516
U.S. 325, 133 L.Ed.2d 796 (1995), a case filed by a single taxpayer relating to
the State's intangibles tax. On July 7, 1995, while the Fulton case was pending
before the United States Supreme Court, the Smith class action was commenced on
behalf of all other taxpayers who had complied with the requirements of the tax
refund statute N.C.G.S. 105-267, and would therefore be entitled to refunds if
Fulton prevailed on its refund claim. These original plaintiffs were later
designated Class A when a second group of plaintiffs were added. The new class,
denominated Class B, consisted of taxpayers who had paid the tax but failed to
comply with the tax refund statute. On February 21, 1996, the United States
Supreme Court held in Fulton that the State's intangibles tax on shares of tax
(by then repealed) violated the Commerce Clause of the United States
Constitution because it discriminated against stock issued by corporations that
do all or part of their business outside of North Carolina. It remanded the case
to the North Carolina Supreme Court to consider remedial issues including
whether the offending provision in the statute (the taxable percentage
deduction) was severable.
      On February 10, 1997, the Supreme Court of North Carolina in the Fulton
remand proceeding severed the taxable deduction provision and invited the
General Assembly to determine the appropriate remedy for the discriminatory tax
treatment of eligible taxpayers who paid the tax but did not benefit from the
deduction. While the General Assembly considered the remedial issues raised by
the Fulton remand, the Smith plaintiffs moved for judgment on their refund
claims. On June 11, 1997, the trail judge in Smith ordered refunds to be made
for tax years 1991-1994 to the Class A plaintiffs and dismissed the Class B
claims. Refunds to Class A taxpayers, totaling approximately $120,000,000, have
substantially been paid, with interest. The Class B plaintiffs appealed, and
their appeal is pending in the North Carolina Court of Appeals. The decision in
Bailey that overruled prior decisions requiring a taxpayer to pay the tax and
file a protest within thirty (30) days may have an adverse impact on the outcome
of this case.
      Shaver v. Boyles, Refrow, and State of North Carolina -- This class action
was filed on January 16, 1998, by intangibles taxpayers who paid intangibles tax
on shares of stock for tax years 1990-1994 and did not receive refunds because
they failed to meet the tax refund statute requirements. There are the same
taxpayers as Class B plaintiffs in Smith, but they claim refund entitlement
under an alleged alternative theory. They claim refunds of approximately
$131,750,000 for tax years 1991-1994 and $80,000,000 for tax year 1990
      In the opinion of the Department of the State Treasurer, the decision in
the Bailey case, if it becomes final, and any adverse decisions in the Patton
and Smith cases, should an adverse decision be rendered, will not materially
adversely affect the State's ability to meet its financial obligations in view
of the State's on-going financial strength and of the current status of its
finances, including its budget stabilization reserve of $500 million. Also, as
of March 31, 1998, in addition to the State's beginning unreserved General Fund
balance of $315 million, the State has realized $585 million in revenues in
excess of expenditures in the General Fund.
      The State is involved in numerous other claims and legal proceedings, many
of which normally occur in governmental operations; however, the North Carolina
Attorney General does not expect any of the other outstanding lawsuits to
materially adversely affect the State's ability to meet its financial
obligations.
      General. The population of the State has increased 13% from 1980, from
5,895,195 to 6,656,810 as reported by the 1990 federal census, and the State
rose from twelfth to tenth in population. The State's estimate of population as
of July, 1997 is 7,436,690. Notwithstanding its rank in population size, North
Carolina is primarily a rural state, having only six municipalities with
populations in excess of 100,000.
      The labor force has undergone significant change during recent years as
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 1996, the State labor force grew about 33% (from 2,855,200 to
3,796,200). Per capita income during the period 1985 to 1996 grew from $11,870
to $22,010, an increase of 85.4%.
      The current economic profile of the State consists of a combination of
industry, agriculture and tourism. As of July 1997, 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 1990, but have demonstrated an upward trend since
1991. The following table reflects the fluctuations in certain key employment
categories.

    The seasonally adjusted unemployment rate in July 1997 was estimated to be
3.7% of the labor force, as compared with 4.8% nationwide. North Carolina's
economy continues to benefit from a vibrant manufacturing sector. Manufacturing
firms employ approximately 24% of the total non-agricultural workforce. North
Carolina has the second highest percentage of manufacturing workers in the
nation. The State's annual value of manufacturing shipments totals $142 billion,
ranking the State eighth in the nation. The State leads the nation in the
production of textiles, tobacco products, furniture and fiberoptic cable, and is
among the largest producers of pharmaceuticals, electronics and
telecommunications equipment. More than 700 international firms have established
a presence in the State. Charlotte is now the second largest financial center in
the country, based on assets of banks headquartered there. The strength of the
State's manufacturing sector also supports the growth in exports; the latest
annual statistics show $8.76 billion in exports, making North Carolina one of
the few states with an export trade surplus.
      In 1996, the State's gross agricultural income of nearly $8.0 billion
placed it eighth in the nation in gross agricultural income. The State ranks
third in the nation in net farm income. According to the State Commissioner of
Agriculture, in 1996, the State ranked first in the nation in the production of
flue-cured tobacco, total tobacco, turkeys and sweet potatoes; second in hog
production, trout and the production of cucumbers for pickles; third in the
value of net farm income poultry and egg products, and greenhouse and nursery
income; fourth in commercial broilers, peanuts, blueberries and strawberries;
and fifth in burley tobacco.
      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.
      Tobacco production, which had been the leading source of agricultural
income in the State, declined in 1995. The poultry industry is now the leading
source of gross agricultural income, at 29%, and the pork industry provides 22%
of the total 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. The tobacco industry remains important to North
Carolina providing approximately 13% of gross agricultural income.
      The number of farms has been decreasing; in 1997 there were approximately
57,000 farms in the State, down from approximately 72,000 in 1987 (a decrease of
about 20% in ten years). However, a strong agribusiness sector supports farmers
with farm inputs (agricultural chemicals and fertilizer, farm machinery, and
building supplies) and processing of commodities produced by farmers (vegetable
canning and cigarette manufacturing). North Carolina's agriculture industry,
including food, fiber and forest products, contributes over $45 billion annually
to the State's economy.
      The North Carolina Department of Commerce, Travel and Tourism Division,
indicates that travel and tourism is increasingly important to the State's
economy. Travel and tourism's $9.8 billion economic impact in 1996 represents a
6.5% increase over 1995. The North Carolina travel and tourism industry directly
supports 167,100 jobs or 4.7% of total non-agricultural employment.
      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 June 1996. Standard & Poor's
reports that North Carolina's rating reflects the State's strong economic
characteristics, sound financial performance, and low debt levels.

                            TAX-EXEMPT TRUST, MULTI-SERIES 301

Gentlemen:

         We have served as counsel for Van Kampen American Capital Distributors,
Inc., Sponsor and Depositor of Insured Municipals Income Trust and Investors'
Quality Tax-Exempt Trust, Multi-Series 301 (hereinafter referred to as the
"Fund"), in connection with the preparation, execution and delivery of a Trust
Agreement dated May 22, 1998 between Van Kampen American Capital Distributors,
Inc., as Depositor, American Portfolio Evaluation Services, a division of Van
Kampen American Capital Investment Advisory Corp., as Evaluator, and The Bank of
New York, as Trustee, pursuant to which the Depositor has delivered to and
deposited Bonds listed in the Schedules to the Trust Agreement with the Trustee
and pursuant to which the Trustee has issued to or on the order of the Depositor
a certificate or certificates representing Units of fractional undivided
interest in and ownership of the several Trusts of said Fund (hereinafter
referred to as the "Units") created under said Trust Agreement.

         In connection therewith, we have examined such pertinent records and
documents and matters of law as we have deemed necessary in order to enable us
to express the opinions hereinafter set forth.

         Based upon the foregoing, we are of the opinion that:

                    1. The execution and delivery of the Trust Agreement and the
         execution and issuance of certificates evidencing the Units in the
         several Trusts of the Fund have been duly authorized; and

                    2. The certificates evidencing the Units in the several
         Trusts of the Fund when duly executed and delivered by the Depositor
         and the Trustee in accordance with the aforementioned Trust Agreement,
         will constitute valid and binding obligations of such Trusts and the
         Depositor in accordance with the terms thereof.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 333-45159) relating to the Units referred to
above and to the use of our name and to the reference to our firm in said
Registration Statement and in the related Prospectus.

                                              Respectfully submitted,

         Re:  Insured Municipals Income Trust and Investors' Quality
                         Tax-Exempt Trust, Multi-Series 301
                   ----------------------------------------------

Gentlemen:

         We have acted as counsel for Van Kampen American Capital Distributors,
Inc., Depositor of Insured Municipals Income Trust and Investors' Quality
Tax-Exempt Trust, Multi-Series 301 (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 22, 1998 (the "Indenture") between Van Kampen
American Capital Distributors, Inc., as Depositor, American Portfolio Evaluation
Services, a division of Van Kampen American Capital 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. For purposes of the following opinions, it is assumed that
each asset of the Trusts is debt, the interest on which is excluded from gross
income for federal income tax purposes.

         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:



<PAGE>






                                                                -1-



                   (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 and original issue discount 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 who is a substantial user (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 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. If a Bond is acquired with accrued interest, that
         portion of the price paid for the accrued interest is added to the tax
         basis of the Bond. When this accrued interest is received, it is
         treated as a return of capital and reduces the tax basis of the Bond.
         If a Bond is purchased for a premium, the amount of the premium is
         added to the tax basis of the Bond. Bond premium is amortized over the
         remaining term of the Bond, and the tax basis of the Bond is reduced
         each tax year by the amount of the premium amortized in that tax year.
         Accordingly, 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 before the date the
         Trust acquired ownership of the Bonds (and the amount of this reduction
         may exceed the amount of accrued interest paid to the seller) and,
         consequently, such Unitholders may have an increase in taxable gain or
         reduction in capital loss upon the disposition of such Units. In
         addition, such basis will be increased by the Unitholder's aliquot
         share of the accrued original issue discount (and market discount, if
         the Unitholder elects to include market discount in income as it
         accrues) with respect to each Bond held by the Trust with respect to
         which there was original issue discount at the time the Bond was issued
         (or which was purchased with market discount) 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
         accrued interest received by the Trust, if any, on Bonds delivered
         after the Unitholders pay for their Units to the extent that such
         interest accrued on the Bonds before the date the Trust acquired
         ownership of the Bonds (and the amount of this reduction may exceed the
         amount of accrued interest paid to the seller), 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 (and market discount, if the Unitholder elects to
         include market discount in income as it accrues) with respect to each
         Bond which, at the time the Bond was issued, had original issue
         discount (or which was purchased with market 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 Bonds
         held by the Trustee will be excludable from Federal gross income if,
         and to the same extent as, such interest would have been so excludable
         if paid in normal course by the Issuer of the defaulted Bonds provided
         that, at the time such policies are purchased, the amounts paid for
         such policies are reasonable, customary and consistent with the
         reasonable expectation that the issuer of the Bonds, rather than the
         insurer, will pay debt service on the Bonds. Paragraph (ii) of this
         opinion is accordingly applicable to insurance proceeds representing
         maturing interest.

                 (vii) Certain bonds in the portfolios of certain of the Insured
         Trusts have been insured by the issuers thereof against default in the
         prompt payment of principal and interest (the "Insured Bonds").
         Insurance has been obtained for such Insured 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 Insured Bonds. Insurance on Insured
         Bonds is effective so long as such Insured Bonds remain outstanding.
         For each of these Insured Bonds, we have been advised that the
         aggregate principal amount of such Insured Bonds listed on the
         portfolio page for the respective Trust was acquired by the applicable
         Trust and are part of the series of such Insured Bonds listed in the
         aggregate principal amount. Based upon the assumption that the Insured
         Bonds of the 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 Insured Bonds will be excludable from federal gross income if,
         and to the same extent as, such interest would have been so excludable
         if paid in normal course by the Issuer provided that, at the time such
         policies are purchased, the amounts paid for such policies are
         reasonable, customary and consistent with the reasonable expectation
         that the issuer of the Insured Bonds, rather than the insurer, will pay
         debt service on the Insured Bonds. Paragraph (ii) of this opinion is
         accordingly applicable to such payment.

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

         Because the Trusts do not include any "private activity" bonds within
the meaning of Section 141 of the Code issued on or after August 8, 1986, none
of the Trust Funds' 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 depends upon the corporation's alternative minimum
taxable income ("AMTI") which is the corporation's taxable income with certain
adjustments.

         Pursuant to Section 56(c) of the Code, one of the adjustment items used
in computing AMTI 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
generally 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.
Legislative proposals have been made that would extend the financial institution
rules to all corporations.

         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) subject to a statutory
de minimis rule. Market discount can arise based on the price a Trust pays for
Bonds or the price a Unitholder pays for his or her Units. Under the Tax Act,
accretion of market discount is taxable as ordinary income; under prior law, the
accretion had been treated as capital gain. Market discount that accretes while
a Trust holds a Bond would be recognized as ordinary income by the Unitholders
when principal payments are received on the Bond, upon sale or at redemption
(including early redemption), or upon the sale or redemption of his or her
Units, unless a Unitholder elects to include market discount in taxable income
as it accrues.

         We have also examined certain laws of the State of Florida, to
determine their applicability to the Florida IM-IT (the "Florida Trust") being
created as part of the Fund and to the holders of Units in the Florida Trust who
are residents of the State of Florida. "Non-Corporate Unitholder" means a
Unitholder of the Florida Trust who is an individual not subject to the Florida
state income tax on corporations under Chapter 220, Florida Statutes and
"Corporate Unitholder" means a Unitholder of the Florida Trusts that is a
corporation, bank or savings association or other entity subject to the Florida
state income tax on corporations or franchise tax imposed on banks or savings
associations under Chapter 220, Florida Statutes.

         Although we express no opinion with respect thereto, in rendering the
opinion expressed herein, we have assumed that the Bonds were validly issued by
the State of Florida or its instrumentalities or municipalities. Based on the
foregoing, it is our opinion that:

                   (a) Neither the Florida Trust nor Non-Corporate Unitholders
         will be subject to the Florida income tax imposed by Chapter 220,
         Florida Statutes. Therefore, any amounts paid to the Florida Trust or
         Non-Corporate Unitholders under an insurance policy issued to the
         Florida Trust, the Issuers, the Underwriters, or the Sponsors thereof,
         or others, which represent maturing interest on defaulted obligations
         held by the Trustee will not be subject to the Florida income tax
         imposed by Chapter 220, Florida Statutes.

                   (b) Corporate Unitholders will be subject to Florida income
         or franchise taxation under Chapter 220, Florida Statutes (1) on
         interest received by the Trust, (2) on payments of interest pursuant to
         any insurance policy, (3) on gain realized when Bonds are sold,
         redeemed or paid at maturity or when insurance payments with respect to
         principal are received by the Trust and (4) on gain on the sale or
         redemption of Units, to the extent such items are allocable to Florida
         under Chapter 220, Florida statutes. In the case of Corporate
         Unitholders that have a commercial domicile in Florida 100 percent of
         the items of income described in clauses (1) through (4) of the
         immediately preceding sentence will be allocable to Florida to the
         extent that such income constitutes "nonbusiness income."

                   (c) Even if interest on indebtedness incurred or continued by
         a Unitholder to purchase Units in the Trust is not deductible for
         Federal income tax purposes, it will reduce interest income on the
         Bonds which is reportable by Corporate Unitholders for Florida income
         tax purposes.

                   (d) Trust Units held by a Florida resident will be includible
         in the resident's estate for Florida estate tax purposes, but if such
         estate is not subject to the Federal estate tax, the estate will not be
         subject to the Florida estate tax. The Florida estate tax is limited to
         the amount of the credit for state death taxes provided for in section
         2011 of the Code, less estate taxes paid to states other than Florida.

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

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

                                                 Very truly yours,

The Bank of New York,
   As Trustee of Insured Municipals
   Income Trust and Investors' Quality
   Tax-Exempt Trust, Multi-Series 301
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 301 (the "Fund")
consisting of Insured Municipals Income Trust, Series 399, Michigan Insured
Municipals Income Trust, Series 150, Florida Insured Municipals Income Trust,
Series 121 and North Carolina Investors' Quality Tax Exempt Trust, Series 94
(individually the "Trust and in the aggregate the "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 American Capital
Distributors, Inc. (the "Depositor"), American Portfolio Evaluation Services, a
division of Van Kampen American Capital Investment Advisory Corp., as Evaluator,
and The Bank of New York as Trustee (the "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 333-45159) 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 of the Trusts exempt, to the
extent indicated in the Prospectus, from income tax, if any, of the State
denominated in the name of that Trust No opinion is expressed herein with regard
to the Federal or State tax aspects (other than New York) of the bonds, the
Fund, the Trusts and units of each of the Trusts (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 of the Trusts, the total principal amount of interest
bearing obligations and/or contracts for the purchase thereof together with an
irrevocable letter of credit in the amount required for the purchase price and
accrued interest, if any, and, 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 those trusts 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 be the Depositor
prior to the Date of Deposit, as more fully set forth in the Prospectus with
respect to each of the Trusts..

         We understand with respect to the obligations described in the
preceding paragraph which are deposited into a trust denominated as "Insured"
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.
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 Trust and with the proceeds from the disposition of obligations held in
each Trust 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 of the Trusts 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 in the case of trusts denominated as
"Insured" 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 Depositor, 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 defines the term
"corporation" to include, among other things, "any business conducted by a
trustee or trustees wherein interest or ownership is evidenced by certificate or
other written instrument."

         The Regulations promulgated under Section 208 provide as follows:

                  A business conducted by a trustee or trustees in which
                  interest or ownership is evidenced by certificate or other
                  written instrument includes, but is not limited to, an
                  association commonly referred to as a "business trust" or
                  "Massachusetts trust". In determining whether a trustee or
                  trustees are conducting a business, the form of the agreement
                  is of significance but is not controlling. The actual
                  activities of the trustee or trustees, not their purposes and
                  powers, will be regarded as decisive factors in determining
                  whether a trust is subject to tax under Article 9-A. The mere
                  investment of funds and the collection of income therefrom,
                  with incidental replacement of securities and reinvestment of
                  funds, does not constitute the conduct of a business in the
                  case of a business conducted by a trustee or trustees.
                  20 NYCRR 1-2.3(b)(2) (July 11, 1990).

         New York cases dealing with the question of whether a trust will be
subject to the franchise tax have also delineated the general rule that where a
trustee merely invests funds and collects and distributes the income therefrom,
the trust is not engaged in business and is not subject to the franchise tax.
BURRELL v. LYNCH, 274 A.D. 347, 84 N.Y.S.2d 171 (3rd Dept. 1948), ORDER
RESETTLED, 274 A.D. 1083, 85 N.Y.S.2d 705 (3rd Dept. 1949).

         In an opinion of the Attorney General of the State of New York, 47 N.Y.
Att'y. 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, and we
assume will not, sell obligations contained in the corpus of the Fund and
reinvest the proceeds therefrom. Further, the power to sell such obligations is
limited to circumstances in which the creditworthiness or soundness of the
obligation is in question or in which cash is needed to pay redeeming Unit
holders or to pay expenses, or where the Fund is liquidated pursuant to the
termination of the Indenture. Only in circumstances in which the issuer of an
obligation attempts to refinance it can the Trustee exchange an obligation for a
new security. In substance, the Trustee will merely collect and distribute
income and will not reinvest any income or proceeds, and the Trustee has no
power to vary the investment of any Unit holder in the Fund under Subpart E of
Part 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).

         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 I,
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 State franchise tax or the New York City general
corporation tax.

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

            3. Unit holders who are not residents of the State of New York are
not subject to the income tax law thereof with respect to any interest or gain
derived from the Fund 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 the State of New
York.

         In addition, we are of the 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.

                                              Very truly yours,

                   (Michigan Insured Municipals Income Trust, Series 150)

Gentlemen:

         We have acted as special Michigan counsel to you as sponsors and
trustees of Insured Municipals Income Trust and Investors' Quality Tax-Exempt
Trust, Multi-Series 301 (Michigan Insured Municipals Income Trust, Series 150)
referred to above (the "Fund"). You have asked that we, acting in such capacity,
render an opinion to you with respect to certain matters relating to the
issuance of the units of fractional undivided interest in the Fund (the "Units")
pursuant to a Registration Statement on Form S-6 filed with the Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Registration Statement").

         You have requested our opinion as to the applicability to the Michigan
Insured Municipals Income Trust (the "Michigan Trust") and the holders of Units
(the "Holders"), each of which Units represents the ownership of a specified
fractional undivided interest in the assets of the Michigan Trust, of the
Michigan Income Tax Act (M.C.L.A. Sections 206.1 et seq.; M.S.A. Sections 7.557
(101) et seq.) (the "Michigan Income Tax"), the City Income Tax Act (M.C.L.A.
Sections 141.501 et seq.; M.S.A. Sections 5.3194 (1) et seq.), which
incorporates the "Uniform City Income Tax Ordinance," the First Class School
District excise tax upon income (M.C.L.A. Section 380.451; M.S.A. S15.4451)
(collectively, the "income tax laws"), the Michigan Single Business Tax Act
(M.C.L.A. Sections 208.1 et seq.; M.S.A. Sections 7.558 (1) et seq.) (the
"Single Business Tax") and the Michigan Tax on Ownership of Intangible Personal
Property (M.C.L.A. Sections 205.131 et seq.; M.S.A. Sections 7.556 (1) et seq.)
(the "Intangibles Tax"). The total repeal of the Intangibles Tax was effective
January 1, 1998 (1995 PA 4 and 5). You have also requested our opinion regarding
the tax status of proceeds payable from an insurance policy to be obtained by
either the Fund or by the issuer of the Bonds involved, guaranteeing prompt
payment of principal and interest on all Bonds in the portfolio of the Fund.

         The Michigan Trust, its formation, its proposed method of operation,
the rights of owners of Certificates representing Units, the nature of such
ownership and the portfolio of investments of the Michigan Trust are described
and set forth in the Prospectus dated May 22, 1998, filed with the Securities
and Exchange commission in Registration No. 333-45159. In giving our opinion set
forth hereunder, we have relied upon the facts contained in such Registration
Statement, including the fact that, at the respective dates of issuance of the
underlying Debt Obligations, opinions of bond counsel to the respective Michigan
authorities issuing such Debt Obligations were given with respect to the
validity of the Debt Obligations and the exemption of the same, and of the
interest thereon, from Michigan taxation.

         Based on the above, it is our opinion that:

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

         Under the income tax laws of the State of Michigan, the Michigan Trust
is not an association taxable as a corporation; the income of the Michigan Trust
will be treated as the income of the Holders of Units of the Michigan Trust and
be deemed to have been received by them when received by the Michigan Trust.
Interest on the Debt Obligations in the Michigan Trust which is exempt from tax
under the Michigan income tax laws when received by the Michigan Trust will
retain its status as tax exempt interest to the Holders of Units of the Michigan
Trust.

         For purposes of the Michigan income tax laws, each Holder of Units of
the Michigan Trust will be considered to have received his pro rata share of
interest on each Debt Obligation in the Michigan Trust when it is received by
the Michigan Trust, and each Holder will have a taxable event when the Michigan
Trust disposes of a Debt Obligation (whether by sale, exchange, redemption or
payment at maturity) or when the Unit Holder redeems or sells his Unit, to the
extent the transaction constitutes a taxable event for Federal income tax
purposes. The tax cost of each Unit to a Unit Holder will be established and
allocated for purposes of the Michigan income tax laws in the same manner as
such cost is established and allocated for Federal income tax purposes.

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

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

         Chapman and Cutler of 111 West Monroe Street, Chicago, Illinois 60603,
are entitled to rely on this opinion as though it were addressed to them.

         We also advise you that, as the Tax Reform Act of 1986 eliminated the
capital gain deduction for tax years beginning after December 31, 1986, the
federal adjusted gross income, the computation base for the Michigan Income Tax,
of a Unit Holder will be increased accordingly to the extent such capital gains
are realized when the Michigan Trust disposes of a Debt Obligation or when the
Unit Holder redeems or sells a Unit, to the extent such transaction constitutes
a taxable event for Federal income tax purposes.

         We hereby consent to the reference to Miller, Canfield, Paddock and
Stone under the heading "Michigan Tax Status" in the Prospectus relating to the
Michigan Trust which is part of the Registration Statement in Registration No.

                 Investors' Quality Tax-Exempt Trust, Multi-Series 301,
              NORTH CAROLINA INVESTORS' QUALITY TAX-EXEMPT TRUST, SERIES 94

Gentlemen:

         We are acting as special North Carolina counsel to the Insured
Municipals Income Trust and Investors' Quality Tax-Exempt Trust, Multi-Series
301 (the "Fund") on North Carolina tax matters relating to North Carolina
Investors' Quality Tax-Exempt Trust, Series 94 (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. 333-45159) under the Securities Act of
1933 (the "Registration Statement"), filed by Van Kampen American Capital
Distributors, 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"). We understand that the portfolio of the
North Carolina Trust consists of bonds issued by the State of North Carolina or
municipalities, authorities or political subdivisions thereof (the "North
Carolina Bonds") or by territories or possessions of the United States. We have
assumed for the purposes of this opinion that the issuers of bonds other than
North Carolina Bonds will be limited to the Commonwealth of Puerto Rico, the
United States virgin Islands or Guam, or their respective public authorities
(collectively, the "Possession bonds") (the North Carolina Debt Obligations and
the Possession Debt Obligations are sometimes referred to herein as 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.

         We have also relied on current interpretations of the North Carolina
Department of Revenue regarding the tax consequences resulting from the
inclusion of Possession bonds in the North Carolina Trust. There can be no
assurance that these interpretations will not be changed during the existence of
the North Carolina Trust. These interpretations are:

                  a. Individual Income Tax Bulletin on the subject of
"Deductions from Federal Taxable Income" located in the publication INDIVIDUAL
INCOME TAX BULLETINS, TAXABLE YEARS 1995 AND 1996, issued by the North Carolina
Department of Revenue effective for tax years 1995 and 1996 (a copy of a
pertinent portion of which is attached hereto as Exhibit A, and which we assume
will remain applicable for subsequent tax years); and

                  b. Letters dated February 3, 1984, and November 16, 1984 of
the Division of Corporate Income and Franchise Taxation, North Carolina
Department of Revenue (copies of which are attached hereto as Exhibits B-1 and
B-2.

         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.

         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 status of the Bonds or income therefrom.

         No opinion is expressed herein as to the effect on the North Carolina
Trust, or on the taxability of the Units or amounts received from the North
Carolina Trust by Unit holders, as a result of the inclusion of Bonds other than
North Carolina Bonds and Possession bonds in the North Carolina Trust.

         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."

        Re:  Insured Municipals Income Trust and Investors' Quality Tax-Exempt 
             Trust, Multi-Series 301, consisting of:  Insured Municipals Income
             Trust, Series 399, Michigan Insured Municipals Income Trust, 
             Series 150 and Florida Insured Municipals Income Trust, Series 121

         Pursuant to your request for a Standard & Poor's rating on the units of
the above-captioned trust, SEC #333-45159 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.

         Standard & Poor's will maintain surveillance on the "AAA" Rating until
June 22, 1999. On this date, the rating will be automatically withdrawn by
Standard & Poor's unless a post effective letter is requested by the Trust.

         You have permission to use the name of Standard & Poor's Corporation
and the above-assigned ratings in connection with your dissemination of
information relating to these units, provided that it is understood that the
ratings are not "market" ratings nor recommendations to buy, hold, or sell the
units of the trust or the securities contained in the trust. Further, it should
be understood the rating on the units does not take into account the extent to
which fund expenses or portfolio asset sales for less than the fund's purchase
price will reduce payment to the unit holders of the interest and principal
required to be paid on the portfolio assets. S&P reserves the right to advise
its own clients, subscribers, and the public of the ratings. S&P relies on the
sponsor and its counsel, accountants, and other experts for the accuracy and
completeness of the information submitted in connection with the ratings.
S&P does not independently verify the truth or accuracy of any such information.

         This letter evidences our consent to the use of the name of Standard &
Poor's Corporation in connection with the rating assigned to the units in the
registration statement or prospectus relating to the units or the trust.
However, this letter should not be construed as a consent by us, within the
meaning of Section 7 of the Securities Act of 1933, to the use of the name of
Standard & Poor's Corporation in connection with the ratings assigned to the
securities contained in the trust. You are hereby authorized to file a copy of
this letter with the Securities and Exchange Commission.

         Please be certain to send us three copies of your final prospectus as
soon as it becomes available. Should we not receive them within a reasonable
time after the closing or should they not conform to the representations made to
us, we reserve the right to withdraw the rating.

         We are pleased to have had the opportunity to be of service to you.  
If we can be of further help, please do not hesitate to call upon us.

                                                 Sincerely,
