Prospectus Part I

   
Insured Municipals Income Trust and Investors' Quality Tax-Exempt Trust,
Multi-Series 278

California IM-IT 156
Michigan IM-IT 139
Virginia Quality 73
    

This Part I of the Prospectus may not be distributed unless accompanied by
Part II. Both parts of this Prospectus should be retained for future reference.

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

   
The Fund. The objectives of the Fund are Federal and, in the case of a State
Trust, state tax-exempt income and conservation of capital through an
investment in a diversified portfolio of tax-exempt bonds. The Fund consists
of three underlying separate unit investment trusts designated as California
Insured Municipals Income Trust, Series 156 (the "California IM-IT
Trust" ), Michigan Insured Municipals Income Trust, Series 139 (the "
Michigan IM-IT Trust" ) and Virginia Investors' Quality Tax-Exempt Trust,
Series 73 (the "Virginia Quality Trust" ). The various trusts are
collectively referred to herein as the "Trusts" or the "State
Trusts" . The California IM-IT and Michigan IM-IT Trusts are sometimes
collectively referred to herein as the "Insured Trusts" and the
Virginia Quality Trust is sometimes referred to herein as the "Quality
Trust" . Each Trust initially consists of delivery statements relating to
contracts to purchase securities and, thereafter, will consist of such
securities as may continue to be held (the "Bonds" or "
Securities" ). Such Securities are interest-bearing obligations issued by
or on behalf of municipalities and other governmental authorities, the
interest on which is, in the opinion of recognized bond counsel to the issuing
governmental authority, exempt from all Federal income taxes under existing
law. In addition, the interest income of each State Trust is, in the opinion
of counsel, exempt to the extent indicated from state and local taxes, when
held by residents of the state where the issuers of Bonds in such Trust are
located.
    

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

<F1>Because certain of the Securities in certain Trusts 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 the respective Trust's termination will be equal to the Principal
Amount (Par Value) of Securities per Unit stated above.

<F2>Sales charges for the Trusts, expressed as a percentage of the Public Offering
Price per Unit and as a percentage of the aggregate offering price of the
Securities are set forth under "Public Offering--General" in Part II
of this Prospectus. In addition, 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 table on page 12 of Prospectus Part II.

<F3>Anyone ordering Units for settlement after the First Settlement Date will pay
accrued interest from such date to the date of settlement (normally three
business days after order) less distributions from the Interest Account
subsequent to the First Settlement Date. For purchases settling on the First
Settlement Date, no accrued interest will be added to the Public Offering
Price. After the initial offering period, the Sponsor's Repurchase Price per
Unit will be determined as described under the caption "Public
Offering--Market for Units" in Part II of this Prospectus.

CALIFORNIA IM-IT TRUST  

- --------------------------------------------------------------------------
General. The California IM-IT Trust consists of 9 issues of Securities. Three
of the Bonds in the California IM-IT Trust are general obligations of the
governmental entities issuing them and are backed by the taxing power thereof.
The remaining issues are payable from the income of a specific project or
authority and are not supported by the issuer's power to levy taxes. These
issues are divided by purpose of issues (and percentage of principal amount to
total California IM-IT Trust) as follows: General Obligations, 3 (26%);
General Purpose, 1 (16%); Higher Education, 1 (16%); Health Care, 1 (15%);
Certificates of Participation, 1 (11%); Public Building, 1 (8%) and Water and
Sewer, 1 (8%). No Bond issue has received a provisional rating.

Risk Factors. The Trust will invest substantially all of its assets in
California Municipal Obligations. The Trust is therefore susceptible to
political, economic or regulatory factors affecting issuers of California
Municipal Obligations. These include the possible adverse effects of certain
California constitutional amendments, legislative measures, voter initiatives
and other matters that are described below. The following information provides
only a brief summary of the complex factors affecting the financial situation
in California (the "State" ) and is derived from sources that are
generally available to investors and are believed to be accurate. No
independent verification has been made of the accuracy or completeness of any
of the following information. It is based in part on information obtained from
various State and local agencies in California or contained in official
statements for various California Municipal Obligations. 

There can be no assurance that future statewide or regional economic
difficulties, and the resulting impact on State or local governmental finances
generally, will not adversely affect the market value of California Municipal
Obligations held in the portfolio of the Trust or the ability of particular
obligors to make timely payments of debt service on (or relating to) those
obligations. 

California's economy is the largest among the 50 states and one of the largest
in the world. The State's population of almost 32 million represents 12.3% of
the total United States population and grew by 27% in the 1980s. While the
State's substantial population growth during the 1980s stimulated local
economic growth and diversification and sustained a real estate boom between
1984 and 1990, it has increased strains on the State's limited water resources
and its infrastructure. Resultant traffic congestion, school over-crowding and
high housing costs have increased demands for government services and may
impede future economic growth. Population growth has slowed between 1991 and
1993 even while substantial immigration has continued, due to a significant
increase in outmigration by California residents. Generally, the household
incomes of new residents have been departing households, which may have a
major long-term socioeconomic and fiscal impact. However, with the California
economy improving, the recent net outmigration within the Continental U.S. is
expected to decrease or be reversed.

From mid-1990 to late 1993, the State's economy suffered its worst recession
since the 1930s, with recovery starting later than for the nation as a whole.
The State has experienced the worst job losses of any post-war recession.
Prerecession job levels may not be realized until near the end of the decade.
The largest job losses have been in Southern California, led by declines in
the aerospace and construction industries. Weakness statewide occurred in
manufacturing, construction, services and trade. Additional military base
closures will have further adverse effects on the State's economy later in the
decade.

Since the start of 1994, the California economy has shown signs of steady
recovery and growth. The State Department of Finance reports net job growth,
particularly in construction and related manufacturing, wholesale and retail
trade, transportation, recreation and services. This growth has offset the
continuing but slowing job losses in the aerospace industry and restructuring
of the finance and utility sectors, Unemployment in the State was down
substantially in 1994 from its 10% peak in January, 1994, but still remains
higher than the national average rate. Retail sales were up strongly in 1994
from year-earlier figures. Delay or slowdown in recovery will adversely affect
State revenues.

Certain California Municipal Obligations may be obligations of issuers which
rely in whole or in part, directly or indirectly, on ad valorem property taxes
as a source of revenue. The taxing powers of California local governments and
districts are limited by Article XIIIA of the California Constitution, enacted
by the voters in 1978 and commonly known as "Proposition 13." Briefly,
Article XIIIA limits to 1% of full cash value the rate of ad valorem property
taxes on real property and generally restricts the reassessment of property to
2% per year, except upon new construction or change of ownership (subject to a
number of exemptions). Taxing entities may, however, raise ad valorem taxes
above the 1% limit to pay debt service on voter-approved bonded indebtedness. 

Under Article XIIIA, the basic 1% ad valorem tax levy is applied against the
assessed value of property as of the owner's date of acquisition (or as of
March 1, 1975, if acquired earlier), subject to certain adjustments. This
system has resulted in widely varying amounts of tax on similarly situated
properties. Several lawsuits have been filed challenging the acquisition-based
assessment system of Proposition 13, and on June 18, 1992 the U.S. Supreme
Court announced a decision upholding Proposition 13. 

Article XIIIA prohibits local governments from raising revenues through ad
valorem property taxes above the 1% limit; it also requires voters of any
governmental unit to give two-thirds approval to levy any "special
tax." Court decisions, however, allowed non-voter approved levy of "
general taxes" which were not dedicated to a specific use. In response to
these decisions, the voters of the State in 1986 adopted an initiative statute
which imposed significant new limits on the ability of local entities to raise
or levy general taxes, except by receiving majority local voter approval.
Significant elements of this initiative, "Proposition 62," have been
overturned in recent court cases. An initiative proposed to re-enact the
provisions of Proposition 62 as a constitutional amendment was defeated by the
voters in November 1990, but such a proposal may be renewed in the future. 

California and its local governments are subject to an annual "
appropriations limit" imposed by Article XIIIB of the California
Constitution, enacted by the voters in 1979 and significantly amended by
Propositions 98 and 111 in 1988 and 1990, respectively. Article XIIIB
prohibits the State or any covered local government from spending "
appropriations subject to limitation" in excess of the appropriations
limit imposed. "Appropriations subject to limitation" are
authorizations to spend "proceeds of taxes," which consists of tax
revenues and certain other funds, including proceeds from regulatory licenses,
user charges or other fees, to the extent that such proceeds exceed the cost
of providing the product or service, but "proceeds of taxes" excludes
most State subventions to local governments. No limit is imposed on
appropriations of funds which are not "proceeds of taxes," such as
reasonable user charges or fees and certain other non-tax funds, including
bond proceeds. 

Among the expenditures not included in the Article XIIIB appropriations limit
are (1) the debt service cost of bonds issued or authorized prior to January
1, 1979, or subsequently authorized by the voters, (2) appropriations arising
from certain emergencies declared by the Governor, (3) appropriations for
certain capital outlay projects, (4) appropriations by the State of post-1989
increases in gasoline taxes and vehicle weight fees, and (5) appropriations
made in certain cases of emergency. 

The appropriations limit for each year is adjusted annually to reflect changes
in cost of living and population, and any transfers of service
responsibilities between government units. The definitions for such
adjustments were liberalized in 1990 by Proposition 111 to follow more closely
growth in California's economy. 

"Excess" revenues are measured over a two-year cycle. With respect to
local governments, excess revenues must be returned by a revision of tax rates
or fee schedules within the two subsequent fiscal years. The appropriations
limit for a local government may be overridden by referendum under certain
conditions for up to four years at a time. With respect to the State, 50% of
any excess revenues is to be distributed to K-12 school districts and
community college districts (collectively, "K-14 districts" ) and the
other 50% is to be refunded to taxpayers. With more liberal annual adjustment
factors since 1988, and depressed revenues since 1990 because of the
recession, few governments, including the State, are currently operating near
their spending limits, but this condition may change over time. Local
governments may by voter approval exceed their spending limits for up to four
years.

Because of the complex nature of Articles XIIIA and XIIIB of the California
Constitution, the ambiguities and possible inconsistencies in their terms, and
the impossibility of predicting future appropriations or changes in population
and cost of living, and the probability of continuing legal challenges, it is
not currently possible to determine fully the impact of Article XIIIA or
Article XIIIB on California Municipal Obligations or on the ability of
California or local governments to pay debt service on such California
Municipal Obligations. It is not presently possible to predict the outcome of
any pending litigation with respect to the ultimate scope, impact or
constitutionality of either Article XIIIA or Article XIIIB, or the impact of
any such determinations upon State agencies or local governments, or upon
their ability to pay debt service on their obligations. Future initiative or
legislative changes in laws or the California Constitution may also affect the
ability of the State or local issuers to repay their obligations. 

Under the California Constitution, debt service on outstanding general
obligation bonds is the second charge to the General Fund after support of the
public school system and public institutions of higher education. Total
outstanding general obligation bond and lease purchase debt of the State
increased from $9.4 billion at June 30, 1987 to $23.5 billion at June 30,
1994. In FY 1993-94, debt service on general obligation bonds and lease
purchase debt was approximately 5.2% of General Fund revenues.

The principal sources of General Fund revenues in 1993-94 were the California
personal income tax (44% of total revenues), the sales tax (35%), bank and
corporation taxes (12%), and the gross premium tax on insurance (3%).
California maintains a Special Fund for Economic Uncertainties (the "
Economic Uncertainties Fund" ), derived from General Fund revenues, as a
reserve to meet cash needs of the General Fund. 

Throughout the 1980s, State spending increased rapidly as the State population
and economy also grew rapidly, including increased spending for many
assistance programs to local governments, which were constrained by
Proposition 13 and other laws. The largest State program is assistance to
local public school districts. In 1988, an initiative (Proposition 98) was
enacted which (subject to suspension by a two-thirds vote of the Legislature
and the Governor) guarantees local school districts and community college
districts a minimum share of State General Fund revenues (currently about
33%). 

Since the start of 1990-91 Fiscal Year, the State has faced adverse economic,
fiscal and budget conditions. The economic recession seriously affected State
tax revenues. It also caused increased expenditures for health and welfare
programs. The State is also facing a structural imbalance in its budget with
the largest programs supported by the General Fund (education, health, welfare
and corrections) growing at rates significantly higher than the growth rates
for the principal revenue sources of the General Fund. These structural
concerns will be exacerbated in coming years by the expected need to
substantially increase capital and operating funds for corrections as a result
of a "Three Strikes" law enacted in 1994. 

As a result of these factors, among others, from the late 1980's until
1992-1993, the State had a period of nearly chronic budget imbalance, with
expenditures exceeding revenues in four out of six years, and the State
accumulated and sustained a budget deficit in the budget reserve, the Special
Fund for Economic Uncertainties ("SFEU" ) approaching $2.8 billion at
its peak at June 30, 1993. Starting in the 1990-91 Fiscal Year and for each
year thereafter, each budget required multibillion dollar actions to bring
projected revenues and expenditures into balance and to close large "
budget gaps" which were identified. The Legislature and Governor
eventually agreed on a number of different steps to produce Budget Acts in the
years 1991-92 to 1994-95, including: significant cuts in health and welfare
program expenditures; transfers of program responsibilities and funding from
the State to local governments, coupled with some reduction in mandates on
local government; transfer of about $3.6 billion in annual local property tax
revenues from cities, counties, redevelopment agencies and some other
districts to local school districts, thereby reducing State funding for
schools; reduction in growth of support for higher education programs, coupled
with increases in student fees; revenue increases (particularly in the 1992-92
Fiscal Year budget), most of which were for a short duration; increased
reliance on aid from the federal government to offset the costs of
incarcerating, educating and providing health and welfare services to
undocumented aliens (although these efforts have produced much less federal
aid than the State Administration has requested) and various on-time
adjustments and accounting changes.

Despite these budget actions, the effects of the recession led to large,
unanticipated deficits in the SFEU, as compared to projected positive
balances. By the start of the 1993-94 Fiscal Year, the accumulated deficit was
so large (almost $2.8 billion) that it was impractical to budget to retire it
in one year, so a two-year program was implemented, using the issuance of
revenue anticipation warrants to carry a portion of the deficit over the end
of the fiscal year. When the economy failed to recover sufficiently in
1993-94, a second two-year plan was implemented in 1994-95, to carry the final
retirement of the deficit into 1995-96.

The combination of stringent budget actions cutting State expenditures, and
the turnaround of the economy by late 1993, finally led to the restoration of
positive financial results. While General Fund revenues and expenditures were
essentially equal in FY 1992-93 (following two years of excess expenditures
over revenues), the General Fund had positive operating results in FY 1993-94
and 1994-95, which have reduced the accumulated budget deficit to around $600
million as of June 30, 1995.

A consequence of the accumulated budget deficits in the early 1990's, together
with other factors such as disbursement of funds to local school districts
"borrowed" from future fiscal years and hence not shown in the annual
budget, was to significantly reduce the State's cash resources available to
pay its ongoing obligations. When the Legislature and the Governor failed to
adopt a budget for the 1992-93 Fiscal Year by July 1, 1992, which would have
allowed the State to carry out its normal annual cash flow borrowing to
replenish its cash reserves, the State Controller was forced to issue
registered warrants ("IOUs" ) to pay a variety of obligations
representing prior years' or continuing appropriations, and mandates from
court orders. Available funds were used to make constitutionally-mandated
payments, such as debt service on bonds and warrants. Between July 1 and
September 4, 1992 the State Controller issued a total of approximately $3.8
billion of registered warrants. After that date, all remaining outstanding
registered warrants (about $2.9 billion) were called for redemptions from
proceeds of the issuance of 1992 Interim Notes after the budget was adopted.

The State's cash condition became so serious in late spring of 1992 that the
State Controller was required to issue revenue anticipation warrants maturing
in the following fiscal year in order to pay the State's continuing
obligations. The State was forced to rely increasingly on external debt
markets to meet its cash needs, as a succession of notes and warrants (both
forms of short-term cash flow financing) were issued in the period from June
1992 to July 1994, often needed to pay previously-maturing notes or warrants.
These borrowings were used also in part to spread out the repayment of the
accumulated budget deficit over the end of a fiscal year.

The State issued $7.0 billion of short-term debt in July, 1994 to meet its
cash flow needs and to finance the deferral of part of the accumulated budget
deficit to the 1995-96 fiscal year. In order to assure repayment of the $4
billion, 22-month part of this borrowing, the State enacted legislation (the
"Trigger Law" ) which can lead to automatic, across-the-board cuts in
General Fund expenditures in either the 1994-95 or 1995-96 fiscal years if
cash flow projections made at certain times during those years show
deterioration from the projections made in July 1994 when the borrowings were
made. On November 15, 1994, the State Controller as part of the Trigger Law
reported that the cash position of the General Fund on June 30, 1995 would be
about $580 million better than earlier projected, so no automatic budget
adjustments were required in 1994-95. The Controller's report showed that loss
of federal funds was offset by higher revenues, lower expenditures, and
certain other increases in cash resources.

For the first time in four years, the State entered the 1995-96 fiscal year
with strengthening revenues based on an improving economy. The major feature
of the Governor's proposed Budget, a 15% phased tax cut, was rejected by the
Legislature.

The 1995-96 Budget Act was signed by the Governor on August 3, 1995, 34 days
after the start of the fiscal year. The Budget Act projects General Fund
revenues and transfers of $44.1 billion. Expenditures are budgeted at $43.4
billion. The Department of Finance projects that, after repaying the last of
the carryover budget deficit, there will be positive balance of less than $30
million in the budget reserve, the Special Fund for Economic Uncertainties, at
June 30, 1996, providing no margin for adverse results during the year.

The Department of Finance projects cash flow borrowings in the 1995-96 Fiscal
Year will be the smallest in many years, comprising about $2 billion of notes
to be issued in April, 1996, and maturing by June 30, 1996. With full payment
of $4 billion of revenue anticipation warrants on April 25, 1996, the
Department sees no further need for borrowing over the end of the fiscal year.
The Department projects that available cash resources to pay State obligations
will be almost $2 billion at June 30, 1996. This "cushion" will be
re-examined by the State Controller on October 15, 1995, in the third step in
the Budget Adjustment Law process. If the Controller believes the available
cash resources on June 30, 1996 will, in fact, be zero or less, her report
would start a process which could lead to automatic budget cuts starting in
December, 1995.

The principal features of the 1995-96 Budget Act, in addition to those noted
above, are additional cuts in health and welfare expenditures (some of which
are subject to approvals or waivers by the federal government); assumed
further federal aid for illegal immigrant costs; and an increase in per-pupil
funding for public schools and community colleges, the first such significant
increase in four years.

State general obligation bonds ratings were reduced in July, 1994 to "
A1" by Moody's and "A" by S&P. Both of these ratings were reduced
from "AAA" levels which the State held until late 1991. There can be
no assurance that such ratings will be maintained in the future. It should be
noted that the creditworthiness of obligations issued by local California
issuers may be unrelated to the creditworthiness of obligations issued by the
State of California, and that there is no obligation on the part of the State
to make payment on such local obligations in the event of default.

The State is involved in certain legal proceedings (described in the State's
recent financial statements) that, if decided against the State, may require
the State to make significant future expenditures or may substantially impair
revenues. Trial courts have recently entered tentative decisions or
injunctions which would overturn several parts of the State's recent budget
compromises. The matters covered by these lawsuits include a deferral of
payments by the State to the Public Employees Retirement System, reductions in
welfare payments, and the use of certain cigarette tax funds for health costs.
All of these cases are subject to further proceedings and appeals, and if the
State eventually loses, the final remedies may not have to be implemented in
one year.

There are a number of State agencies, instrumentalities and political
subdivisions of the State that issue Municipal Obligations, some of which may
be conduit revenue obligations payable from payments from private borrowers.
These entities are subject to various economic risks and uncertainties, and
the credit quality of the securities issued by them may vary considerably from
the credit quality of the obligations backed by the full faith and credit of
the State.

Property tax revenues received by local governments declined more than 50%
following passage of Proposition 13. Subsequently, the California Legislature
enacted measures to provide for the redistribution of the State's General Fund
surplus to local agencies, the reallocation of certain State revenues to local
agencies and the assumption of certain governmental functions by the State to
assist municipal issuers to raise revenues. Total local assistance from the
State's General Fund was budgeted at approximately 75% of General Fund
expenditures in recent years, including the effect of implementing reductions
in certain aid programs. To reduce State General Fund support for school
districts, the 1992-93 and 1993-94 Budget Acts caused local governments to
transfer $3.9 billion of property tax revenues to school districts,
representing loss of the post-Proposition 13 "bailout" aid. The
largest share of these transfers came from counties, and the balance from
cities, special districts and redevelopment agencies. In order to make up this
shortfall, the Legislature proposed and voters approved in 1993 dedicating
0.5% of the sales tax to counties and cities for public safety purposes. In
addition, the Legislature has changed laws to relieve local governments of
certain mandates, allowing them to reduce costs.

To the extent the State should be constrained by its Article XIII
appropriations limit, or its obligation to conform to Proposition 98, or other
fiscal considerations, the absolute level, or the rate of growth, of State
assistance to local governments may be further reduced. Any such reductions in
State aid could compound the serious fiscal constraints already experienced by
many local governments, particularly counties. At lease one rural county
(Butte) publicly announced that it might enter bankruptcy proceedings in
August 1990, although such plans were put off after the Governor approved
legislation to provide additional funds for the county. Other counties have
also indicated that their budgetary condition is extremely grave. The Richmond
Unified School District (Contra Costa County) entered bankruptcy proceedings
in May 1991 but the proceedings have been dismissed. Los Angeles County, the
largest in the State, has reported severe fiscal problems, leading to a
nominal $1.2 billion deficit in its $11 billion budget for the 1995-96 Fiscal
Year. To balance the budget, the county has imposed severe cuts in services,
particularly for health care. The Legislature is considering actions to help
alleviate the County's fiscal problems, but none were completed before August
15, 1995. As a result of its bankruptcy proceedings (discussed further below)
Orange County also has implemented stringent cuts in services and has laid off
workers.

California Municipal Obligations which are assessment bonds may be adversely
affected by a general decline in real estate values or a slowdown in real
estate sales activity. In many cases, such bonds are secured by land which is
undeveloped at the time of issuance but anticipated to be developed within a
few years after issuance. In the event of such reduction or slowdown, such
development may not occur or may be delayed, thereby increasing the risk of a
default on the bonds. Because the special assessments or taxes securing these
bonds are not the personal liability of the owners of the property assessed,
the lien on the property is the only security for the bonds. Moreover, in most
cases the issuer of these bonds is not required to make payments on the bonds
in the event of delinquency in the payment of assessments or taxes, except
from amounts, if any, in a reserve fund established for the bonds. 

Certain California long-term lease obligations, though typically payable from
the general fund of the municipality, are subject to "abatement" in
the event the facility being leased is unavailable for beneficial use and
occupancy by the municipality during the term of the lease. Abatement is not a
default, and there may be no remedies available to the holders of the
certificates evidencing the lease obligation in the event abatement occurs.
The most common cases of abatement are failure to complete construction of the
facility before the end of the period during which lease payments have been
capitalized and uninsured casualty losses to the facility (e.g., due to
earthquake). In the event abatement occurs with respect to a lease obligation,
lease payments may be interrupted (if all available insurance proceeds and
reserves are exhausted) and the certificates may not be paid when due. 

Several years ago the Richmond Unified School District (the "District" 
) entered into a lease transaction in which certain existing properties of the
District were sold and leased back in order to obtain funds to cover operating
deficits. Following a fiscal crisis in which the District's finances were
taken over by a State receiver (including a brief period under bankruptcy
court protection), the District failed to make rental payments on this lease,
resulting in a lawsuit by the Trustee for the Certificate of Participation
holders, in which the State was a named defendant (on the grounds that it
controlled the District's finances). One of the defenses raised in answer to
this lawsuit was the invalidity of the original lease transaction. The trial
court has upheld the validity of the District's lease, and the case has been
settled. Any judgment in any future case against the position asserted by the
Trustee in the Richmond case may have adverse implications for lease
transactions of a similar nature by other California entities. 

The repayment of industrial development securities secured by real property
may be affected by California laws limiting foreclosure rights of creditors.
Securities backed by health care and hospital revenues may be affected by
changes in State regulations governing cost reimbursements to health care
providers under Medi-Cal (the State's Medicaid program), including risks
related to the policy of awarding exclusive contracts to certain hospitals. 

Limitations on ad valorem property taxes may particularly affect "tax
allocation" bonds issued by California redevelopment agencies. Such bonds
are secured solely by the increase in assessed valuation of a redevelopment
project area after the start of redevelopment activity. In the event that
assessed values in the redevelopment project decline (e.g., because of a major
natural disaster such as an earthquake), the tax increment revenue may be
insufficient to make principal and interest payments on these bonds. Both
Moody's and S&P suspended ratings on California tax allocation bonds after the
enactment of Articles XIIIA and XIIIB, and only resumed such ratings on a
selective basis. 

Proposition 87, approved by California voters in 1988, requires that all
revenues produced by a tax rate increase go directly to the taxing entity
which increased such tax rate to repay that entity's general obligation
indebtedness. As a result, redevelopment agencies (which, typically, are the
Issuers of tax allocation securities) no longer receive an increase in tax
increment when taxes on property in the project area are increased to repay
voter-approved bonded indebtedness. 

The effect of these various constitutional and statutory changes upon the
ability of California municipal securities issuers to pay interest and
principal on their obligations remains unclear. Furthermore, other measures
affecting the taxing or spending authority of California or its political
subdivisions may be approved or enacted in the future. Legislation has been or
may be introduced which would modify existing taxes or other revenue-raising
measures or which either would further limit or, alternatively, would increase
the abilities of state and local governments to impose new taxes or increase
existing taxes. It is not presently possible to determine the impact of any
such legislation on California Municipal Obligations in which the Fund may
invest, future allocations of state revenues to local governments or the
abilities of state or local governments to pay the interest on, or repay the
principal of, such California Municipal Obligations. 

Substantially all of California is within an active geologic region subject to
major seismic activity. Northern California in 1989 and Southern California in
1994 experienced major earthquakes causing billions of dollars in damages. The
federal government provided more than $1.8 billion in aid for both
earthquakes, and neither event is expected to have any long-term negative
economic impact. Any California Municipal Obligation in the Portfolio could be
affected by an interruption of revenues because of damaged facilities, or,
consequently, income tax deductions for casualty losses or property tax
assessment reductions. Compensatory financial assistance could be constrained
by the inability of (i) an issuer to have obtained earthquake insurance
coverage at reasonable rates; (ii) an insurer to perform on its contracts of
insurance in the event of widespread losses; or (iii) the Federal or State
government to appropriate sufficient funds within their respective budget
limitations. 

On January 17, 1994, a major earthquake with an estimated magnitude 6.8 on the
Richter scale struck the Los Angeles area, causing significant property damage
to public and private facilities, presently estimated at $15-20 billion. While
over $9.5 billion of federal aid, and a projected $1.9 billion of State aid,
plus insurance proceeds, will reimburse much of that loss, there were bill be
come ultimate loss of health and income in the region, in addition to costs of
the disruption caused by the event. Short-term economic projections are
generally neutral, as the infusion of aid will restore billions of dollars to
the local economy within a few months; already the local construction industry
has picked up. Although the earthquake will hinder recovery from the recession
in Southern California, already hard-hit, its long-term impact is not expected
to be material in the context of the overall wealth of the region. Almost five
years after the event, there are few remaining effects of the 1989 Loma Prieta
earthquake in northern California (which, however, caused less severe damage
than Northridge).

On December 7, 1994, Orange County, California (the "County" ),
together with its pooled investment fund (the "Pools" ) filed for
protection under Chapter 9 of the federal Bankruptcy Code, after reports that
the Pools had suffered significant market losses in its investments caused a
liquidity crisis for the Pools and the County. Approximately 180 other public
entities, most but not all located in the County, were also depositors in the
Pools. The County estimated the Pools' loss at about $1.64 billion, or 23%, of
its initial deposits of around $7.5 billion. Many of the entities which kept
moneys in the Pools, including the County, faced cash flow difficulties
because of the bankruptcy filing and may be required to reduce programs or
capital projects. Moody's and Standard & Poor's have suspended, reduced to
below investment grade levels, or placed on "Credit Watch" various
securities of the County and the entities participating in the Pools.

On May 2, 1995, the Bankruptcy Court approved a settlement agreement covering
claims of the other participating entities against the County and the Pools.
Most participants have received in cash 80% (90% for school districts) of
their Pools' investment; the balance is to be paid in the future. The County
succeeded in deferring, by consent, until June 30, 1996, the repayment of $800
million of short-term obligations due in July and August, 1995; these notes
are, however, considered to be in default by Moody's and S&P. On June 27,
1995, County voters turned down a proposal for a temporary 0.5% increase in
the local sales tax, making the County's fiscal recovery much harder.

The State of California has no obligation with respect to any obligations or
securities of the County or any of the other participating entities, although
under existing legal precedents, the State may be obligated to ensure that
school districts have sufficient funds to operate. All school districts were
able to meet their obligations in the 1994-95 Fiscal Year.

Tax Status. For a discussion of the Federal tax status of income earned on
California IM-IT Trust Units, see "Federal Tax Status" in Part II of
this Prospectus. 

In the opinion of Orrick, Herrington & Sutcliffe, special counsel to the Fund
for California tax matters, under existing California income and property tax
law applicable to individuals who are California residents: 

(1)the California IM-IT Trust is not an association taxable as a corporation
and the income of the California IM-IT Trust will be treated as the income of
the Unitholders under the income tax laws of California; 

(2)amounts treated as interest on the underlying Securities in the California
IM-IT Trust which are exempt from tax under California personal income tax and
property tax laws when received by the California IM-IT Trust will, under such
laws, retain their status as tax-exempt interest when distributed to
Unitholders. However, interest on the underlying Securities attributed to a
Unitholder which is a corporation subject to the California franchise tax laws
may be includable in its gross income for purposes of determining its
California franchise tax. Further, certain interest which is attributable to a
Unitholder subject to the California personal income tax and which is treated
as an item of tax preference for purposes of the federal alternative minimum
tax pursuant to Section 57(a)(5) of the Internal Revenue Code of 1986 may also
be treated as an item of tax preference that must be taken into account in
computing such Unitholder's alternative minimum taxable income for purposes of
the California alternative minimum tax enacted by 1987 California Statutes,
chapter 1138. However, because of the provisions of the California
Constitution exempting the interest on bonds issued by the State of
California, or by local governments within the state, from taxes levied on
income, the application of the new California alternative minimum tax to
interest otherwise exempt from the California personal income tax in some
cases may be unclear; 

(3)under California income tax law, each Unitholder in the California IM-IT
Trust will have a taxable event when the California IM-IT Trust disposes of a
Security (whether by sale, exchange, redemption, or payment at maturity) or
when the Unitholder redeems or sells Units. Because of the requirement that
tax cost basis be reduced to reflect amortization of bond premium, under some
circumstances a Unitholder may realize taxable gains when Units are sold or
redeemed for an amount equal to, or less than, their original cost. The total
cost of each Unit in the California IM-IT Trust to a Unitholder is allocated
among each of the Bond issues held in the California IM-IT Trust (in
accordance with the proportion of the California IM-IT Trust comprised by each
Bond issue) in order to determine his per Unit tax cost for each Bond issue;
and the tax cost reduction requirements relating to amortization of bond
premium will apply separately to the per Unit tax cost of each Bond issue.
Unitholders' bases in their units, and the bases for their fractional interest
in each Trust asset, may have to be adjusted for their pro rata share of
accrued interest received, if any, on Securities delivered after the
Unitholders' respective settlement dates; 

(4)under the California personal property tax laws, bonds (including the
Securities in the California IM-IT Trust) or any interest therein is exempt
from such tax; 

(5)any proceeds paid under the insurance policy issued to the California IM-IT
Trust with respect to the Securities which represent maturing interest on
defaulted obligations held by the Trustee will be exempt from California
personal income tax if, and to the same extent as, such interest would have
been so exempt if paid by the issuer of the defaulted obligations; and 

(6)under Section 17280(b)(2) of the California Revenue and Taxation Code,
interest on indebtedness incurred or continued to purchase or carry Units of
the California IM-IT Trust is not deductible for the purposes of the
California personal income tax. While there presently is no California
authority interpreting this provision, Section 17280(b)(2) directs the
California Franchise Tax Board to prescribe regulations determining the proper
allocation and apportionment of interest costs for this purpose. The Franchise
Tax Board has not yet proposed or prescribed such regulations. In interpreting
the generally similar Federal provision, the Internal Revenue Service has
taken the position that such indebtedness need not be directly traceable to
the purchase or carrying of Units (although the Service has not contended that
a deduction for interest on indebtedness incurred to purchase or improve a
personal residence or to purchase goods or services for personal consumption
will be disallowed). In the absence of conflicting regulations or other
California authority, the California Franchise Tax Board generally has
interpreted California statutory tax provisions in accord with Internal
Revenue Service interpretations of similar Federal provisions. 

At the respective times of issuance of the Securities, opinions relating to
the validity thereof and to the exemption of interest thereon from Federal
income tax and California personal income tax are rendered by bond counsel to
the respective issuing authorities. Except in certain instances in which
Orrick, Herrington & Sutcliffe acted as bond counsel to issuers of Securities,
and as such made a review of proceedings relating to the issuance of certain
Securities at the time of their issuance, Orrick, Herrington & Sutcliffe has
not made any special review for the California IM-IT Trust of the proceedings
relating to the issuance of the Securities or of the basis for such opinions.

MICHIGAN IM-IT TRUST 

- --------------------------------------------------------------------------
General. The Michigan IM-IT Trust consists of 8 issues of Securities. Five of
the Bonds in the Michigan IM-IT Trust are general obligations of the
governmental entities issuing them and are backed by the taxing power thereof.
The remaining issues are payable from the income of a specific project or
authority and are not supported by the issuer's power to levy taxes. These
issues are divided by purpose of issues (and percentage of principal amount to
total Michigan IM-IT Trust) as follows: General Obligations, 5 (53%); Health
Care, 1 (17%); Other Care, 1 (17%) and Water and Sewer, 1 (13%). No Bond issue
has received a provisional rating.

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

In July 1995, Moody's Investors Service, Inc. raised the State's general
obligation bond rating to "Aa" . In October 1989, Standard & Poor's
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 recent years, the State has reported its financial results in accordance
with generally accepted accounting principles. For the fiscal years ended
September 30, 1990 and 1991, the State reported negative year-end balances in
the General Fund/School Aid Fund of $310.4 million and $169.4 million,
respectively. The State ended each of the 1992, 1993, 1994 and 1995 fiscal
years with its General Fund/School Aid Fund in balance, after having made
substantial transfers to the Budget Stabilization Fund in 1993, 1994 and 1995.
A positive cash balance in the combined General Fund/School Aid Fund was
recorded at September 30, 1990. In the 1991 through 1993 fiscal years, the
State experienced deteriorating cash balances which necessitated short-term
borrowing and the deferral of certain scheduled cash payments. The State did
not borrow for cash flow purposes in 1994, but borrowed $500 million on March
9, 1995, which was repaid on September 29, 1995 and $900 million on February
20, 1996, with a maturity date of September 30, 1996. The State's Budget
Stabilization Fund received transfers of $283 million in 1993, $464 million in
1994 and $320 million in 1995, bringing the balance in the Budget
Stabilization Fund, after making certain transfers out, to $988 million at
September 30, 1995.

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

On March 15, 1994, Michigan voters approved a school finance reform amendment
to the State's Constitution which, among other things, 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 adopted in 1994 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, the State
reduced revenue sharing payments to municipalities below that level provided
under formulas by an increasing amount in each of the last five fiscal years
and by a budgeted amount of $81.26 million in the 1996 fiscal year.

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

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

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

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

Under the Michigan Intangibles Tax, the Michigan IM-IT Trust is not taxable
and the pro rata ownership of the underlying Bonds, as well as the interest
thereon, will be exempt to the Unitholders to the extent the Michigan IM-IT
Trust consists of obligations of the State of Michigan or its political
subdivisions or municipalities, or of obligations of possessions of the United
States. The Intangibles Tax is being phased out, with reductions of
twenty-five percent (25%) in 1994 and 1995, fifty percent (50%) in 1996, and
seventy-five percent (75%) in 1997, with total repeal 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 eliminates the capital gain deduction for tax
years beginning after December 31, 1986, the federal adjusted gross income,
the computation base for the Michigan Income Tax, of a Unitholder will be
increased accordingly to the extent such capital gains are realized when the
Michigan IM-IT Trust disposes of a Bond or when the Unitholder redeems or
sells a Unit, to the extent such transaction constitutes a taxable event for
Federal income tax purposes.

<F1>During the first year the Trustee will reduce its fee by approximately $.21
per Unit (which amount is the estimated interest to be earned per Unit prior
to the expected delivery dates for the "when, as and if issued" Bonds
included in this Trust). Should such estimated interest exceed such amount,
the Trustee will reduce its fee up to its annual fee. After the first year,
the Trustee's fee will be that amount indicated above. Estimated Annual
Interest Income per Unit will be increased to $53.73. Estimated Annual Expense
per Unit (excluding insurance) will be increased to $2.43 and $2.01 under the
monthly and semi-annual distribution plans, respectively; and Estimated Net
Annual Interest Income per Unit will remain the same as shown. See "
Estimated Current Returns and Estimated Long-Term Returns" in Part II of
this Prospectus.

<F2>Excluding insurance costs. The Estimated Annual Expenses are expected to
fluctuate periodically (see "Trust Administration--Fund Administration and

<F3>The Estimated Current Returns and Estimated Long-Term Returns are increased
for transactions entitled to a reduced sales charge. See "Unitholder
Explanations--Public Offering--General" in Part II of this Prospectus. For
a discussion of how these returns are calculated, see "Unitholder
Explanations--Estimated Current Returns and Estimated Long-Term Returns" 
in Part II of this Prospectus. These figures are based on estimated per Unit
cash flows. Estimated cash flows will vary with changes in fees and expenses,
with changes in current interest rates and with the principal prepayment,
redemption, maturity, call, exchange or sale of the underlying Securities. The
estimated cash flows for this Series are set forth under "Other
Matters--Estimated Cash Flows to Unitholders" .

<F4>Based on the size of the Trust on the Date of Deposit and assuming all
Unitholders had chosen the semi-annual distribution plan, the Trustee's
estimated annual fees for ordinary recurring services would initially amount
to $1,517. Assuming in the alternative that all Unitholders had elected the
monthly distribution plan, such fees would initially amount to $2,707.

VIRGINIA QUALITY TRUST 

- --------------------------------------------------------------------------
General. The Virginia Quality Trust consists of 8 issues of Securities. One of
the Bonds in the Virginia Quality Trust is a general obligation of the
governmental entity issuing it and is backed by the taxing power thereof. The
remaining issues are payable from the income of a specific project or
authority and are not supported by the issuer's power to levy taxes. These
issues are divided by purpose of issues (and percentage of principal amount to
total Virginia Quality Trust) as follows: Water and Sewer, 2 (28%); Public
Building, 2 (25%); Airport, 1 (17%); Health Care, 1 (16%); General
Obligations, 1 (10%) and Retail Electric/Gas, 1 (4%). No Bond issue has
received a provisional rating. 

Risk Factors. The Commonwealth's financial condition is supported by a
broad-based economy, including manufacturing, tourism, agriculture, ports,
mining and fisheries. Manufacturing continues to be a major source of
employment, ranking behind only services, wholesale and retail trade, and
government (Federal, state and local). The Federal government is a major
employer in Virginia due to the heavy concentration of Federal employees in
the metropolitan Washington, D.C. segment of northern Virginia and the
military employment in the Hampton Roads area, which houses the nation's
largest concentration of military installations, although civilian defense
employment has been adversely affected by the retrenchment of the military
sector and is likely to decrease further.

Economic growth continued in fiscal year 1995, mimicking neither the boom of
the late 1980's nor the 1990-1991 recession. Personal income continued to rise
in real terms during the first three quarters of the fiscal year but only at
1.1 percent in the first quarter of calendar year 1995. Employment continued
to give brighter news and unemployment dropped to 4.7 percent compared to the
national rate of 5.7 percent. While recent decisions by large private firms to
locate or expand in Virginia provide encouragement, additional company
downsizings and defense cutbacks have now been joined by the prospect of major
cuts in federal employment as threats to the Commonwealth's economic health.

Year-to-year percentage changes in the Commonwealth personal income generally
parallel those at the national level. Virginia's per capita personal income of
$22,501 for 1994 was 104 percent of national per capita income. In comparison
with the South Atlantic region, Virginia's real per capita income was 106
percent in 1993 and 1994.

Virginia's nonagricultural employment figure has also generally followed the
national economy. For fiscal year 1994 Virginia's nonagricultural employment
rose 2.3 percent, as did U.S. employment. Total nonagricultural employment for
Virginia in June 1995 was a record high. During the period 1988-1990, the
Commonwealth substantially outpaced the nation in growth of nonagricultural
employment; however, the trend lines for both have been nearly parallel since
1990. For the period 1985-1990, the Commonwealth went ahead of the South
Atlantic region, but was hit harder by the recession in 1990 and the defense
adjustment. Since then, the region has outperformed the Commonwealth.

The unemployment picture brightened in Virginia in fiscal year 1995. For the
first 10 months of 1994, Virginia's unemployment rate of 5 percent was 21
percent below the national average of 6.3 percent. Virginia's unemployment
rate has typically been one of the lowest in the nation, largely as a result
of the balance found in Virginia's economy, and has remained consistently
below the national rate. Rates of unemployment in excess of 9 percent were
found in southwest Virginia where mining jobs have been lost and the lowest
unemployment rates were seen in the Northern Virginia, Charlottesville and
Richmond areas at under 4 percent.

Employment trends in Virginia have varied from sector to sector and from
region to region. The growth patterns were similar to those in fiscal year
1994. This past fiscal year's growth was led by a 6.3 percent employment jump
in the construction sector and 5.4 percent in services. Federal civilian
employment slipped 2.3 percent, the result of continued defense cutbacks and
an effort to downsize. The drop in mining accelerated to 9.8 percent from a
7.7 percent drop in the previous year. Manufacturing has lost 25,100 jobs
during the five-year period beginning in 1991, emphasizing dramatic evidence
of the shift to a service economy from a goods-providing economy. Employment
trends also varied among regions. All of the Commonwealth's metropolitan
statistical areas showed increased employment from fiscal year 1994 to fiscal
year 1995, ranging from .7 percent to 4.3 percent, with most employment
increases being experienced in metropolitan areas.

While Virginia has nearly completed an economic recovery from the 1990-91
recession, its period of eclipsing national and South Atlantic regional
economic outcomes may be over. In both measures of income and particularly of
employment of the South Atlantic region seems to be gaining. Virginia
continues to lead the U.S. as a whole in per capita income but no longer
exceeds the nation in year-to-year changes income and level of employment. The
implementation of announced defense cutbacks, the duration of the period of
economic growth, and the impact of potential cuts in federal spending are
continuing sources of concern. Dependence of Virginia's international trade
upon tobacco exports is worrisome for the long term. Growing interest in
Virginia by major corporations as a site for new facilities is the brightest
hope for the future of the state economy.

The Commonwealth of Virginia has historically operated on a fiscally
conservative basis and is required by its Constitution to have a balanced
biennial budget. At the end of the June 30, 1995, fiscal year, the General
Fund had an ending fund balance computed on a budgetary cash basis of $350.7
million, of which $151.6 million was in required reserves. Approximately
$199.1 million thereof was designated for expenditure during the next fiscal
year, leaving no undesignated, unreserved fund balance. This is the first year
since fiscal year 1991 that there has not been an undesignated fund balance.
Computed on a modified accrual basis in accordance with generally accepted
accounting principles, the General Fund balance at the end of the fiscal year
ended June 30, 1995, was $(86.4) million, compared with a General Fund balance
at the end of the fiscal year ended June 30, 1994, of $185.3 million. The
fiscal year deficit in the General Fund when measured on the GAAP basis of
accounting is the result of a settlement and subsequent ruling by the Virginia
Supreme Court in the case of Harper v. Department of Taxation relating to the
tax treatment of federal retiree's benefits. 

As of June 30, 1995, total debt of the Commonwealth aggregated $9.3 billion.
Of that amount, $2.7 billion was tax-supported. Outstanding general obligation
debt backed by the full faith and credit of the Commonwealth was $963 million
at June 30, 1995. Of that amount, $524 million was also secured by revenue
producing capital projects.

The Virginia Constitution contains limits on the amount of general obligation
bonds which the Commonwealth can issue. These limits are substantially in
excess of current levels of outstanding bonds, and at June 30, 1995 would
permit an additional total of approximately $6 billion of bonds secured by
revenue-producing projects and approximately $6.1 billion of unsecured general
obligation bonds, with not more than approximately $1 billion of the latter to
be issued in any four-year period. Bonds which are not secured by
revenue-producing projects must be approved in a state-wide election. 

The Commonwealth of Virginia maintains a "triple A" rating from
Standard & Poor's, Moody's and Fitch Investors Service on its general
obligation indebtedness, reflecting in part its sound fiscal management,
diversified economic base and low debt ratios. There can be no assurance that
these conditions will continue. Nor are these same conditions necessarily
applicable to securities which are not general obligations of the
Commonwealth. Securities issued by specific municipalities, governmental
authorities or similar issuers may be subject to economic risks or
uncertainties peculiar to the issuers of such securities or the sources from
which they are to be paid. 

Tax Status. For a discussion of the Federal tax status of income earned on
Virginia Quality Trust Units see "Federal Tax Status" in Part II of
this Prospectus. 

The assets of the Trust will consist of interest-bearing obligations issued by
or on behalf of the Commonwealth of Virginia ("Virginia" ) or counties,
municipalities, authorities or political subdivisions thereof (the "
Bonds" ). 

Neither the Sponsor nor its counsel have independently examined the Bonds to
be deposited in and held in the Trust. However, although no opinion is
expressed herein regarding such matters, it is assumed that: (i) the Bonds
were validly issued, (ii) the interest thereon is excludible from gross income
for federal income tax purposes and (iii) the interest thereon is exempt from
income tax imposed by Virginia that is applicable to individuals and
corporations (the "Virginia Income Tax" ). The opinion set forth below
does not address the taxation of persons other than full time residents of
Virginia. 

In the opinion of Chapman and Cutler, special counsel to the Fund for Virginia
tax matters, under existing law as of the date of this prospectus and based
upon the assumptions set forth above: 

The Virginia Quality Trust is not an association taxable as a corporation for
purposes of the Virginia Income Tax and each Unitholder of the Trust will be
treated as the owner of a pro rata portion of each of the assets held by the
Trust and the income of such portion of the Virginia Quality Trust will be
treated as income of the Unitholder for purposes of the Virginia Income Tax. 

Income on the Bonds which is exempt from Virginia Income Tax when received by
the Virginia Quality Trust, and which would be exempt from Virginia Income Tax
if received directly by a Unitholder, will retain its status as exempt from
such tax when received by the Trust and distributed to such Unitholder.

Each Unitholder will recognize gain or loss for purposes of the Virginia
Income Tax if the Trustee disposes of a bond (whether by redemption, sale or
otherwise) or if the Unitholder redeems or sells Units of the Trust to the
extent that such a transaction results in a recognized gain or loss to such
Unitholder for federal income tax purposes, except as described in this
paragraph. Virginia has by law provided that all income from certain
tax-exempt obligations issued under the laws of Virginia, including any
profits made from the sale of such Bonds, shall be exempt from all taxation by
Virginia. Although we express no opinion, the Virginia Department of Taxation
has indicated that the gain on the sale of such tax-exempt obligations,
recognized for federal income tax purposes, would not be subject to Virginia
income taxation. Accordingly, any such gain relating to the disposition of any
Bond that would not be subject to Virginia Income Tax if the Bond was held
directly by a Unitholder will retain its tax-exempt status for purposes of the
Virginia Income Tax when the Bond is disposed of by the Virginia Quality Trust
or when the Unitholder is deemed to have disposed of his pro rata portion of
such Bond upon the disposition of his Unit, provided that such gain can be
determined with reasonable certainty and substantiated.

The Virginia Income Tax does not permit a deduction of interest paid on
indebtedness incurred or continued to purchase or carry Units in the Virginia
Quality Trust to the extent that interest income related to the ownership of
Units is exempt from the Virginia Income Tax. 

In the case of Unitholders subject to the Virginia Bank Franchise Tax, the
income derived by such a Unitholder from his pro rata portion of the Bonds
held by the Virginia Quality Trust may affect the determination of such
Unitholder's Bank Franchise Tax. Prospective investors subject to the Virginia
Bank Franchise Tax should consult their tax advisors. Chapman and Cutler has
expressed no opinion with respect to taxation under any other provisions of
Virginia law. Ownership of the Units may result in collateral Virginia tax
consequences to certain taxpayers. Prospective investors should consult their
tax advisors as to the applicability of any such collateral consequences.

<F1>The estimated annual expenses are expected to fluctuate periodically (see "
Trust Administration--Fund Administration and Expenses--Miscellaneous
Expenses" in Part II of this Prospectus).

<F2>The Estimated Current Returns and Estimated Long-Term Returns are increased
for transactions entitled to a reduced sales charge. See "Unitholder
Explanations--Public Offering--General" in Part II of this Prospectus. For
a discussion of how these returns are calculated, see "Unitholder
Explanations--Estimated Current Returns and Estimated Long-Term Returns" 
in Part II of this Prospectus. These figures are based on estimated per Unit
cash flows. Estimated cash flows will vary with changes in fees and expenses,
with changes in current interest rates and with the principal prepayment,
redemption, maturity, call, exchange or sale of the underlying Securities. The
estimated cash flows for this Series are set forth under "Other
Matters--Estimated Cash Flows to Unitholders" .

<F3>Based on the size of the Trust on the Date of Deposit and assuming all
Unitholders had chosen the semi-annual distribution plan, the Trustee's
estimated annual fees for ordinary recurring services would initially amount
to $1,535. Assuming in the alternative that all Unitholders had elected the
monthly distribution plan, such fees would initially amount to $2,739.

Portfolios" . 

NOTES TO PORTFOLIOS
As of the Date of Deposit: August 15, 1996

- --------------------------------------------------------------------------
(1)All Securities are represented by "regular way" or "when
issued" contracts for the performance of which an irrevocable letter of
credit, obtained from an affiliate of the Trustee, has been deposited with the
Trustee. At the Date of Deposit, Securities may have been delivered to the
Sponsor pursuant to certain of these contracts; the Sponsor has assigned to
the Trustee all of its right, title and interest in and to such Securities.
Contracts to acquire Securities were entered into during the period from
August 6,1996 to August 14,1996. These Securities have expected settlement
dates ranging from August 15,1996 to August 28,1996 (see "Unitholder
Explanations" in Part II of this Prospectus).
    

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

(3)There is shown under this heading the year in which each issue of Bonds is
initially or currently callable and the call price for that year. Each issue
of Bonds continues to be callable at declining prices thereafter (but not
below par value) except for original issue discount bonds which are redeemable
at prices based on the issue price plus the amount of original issue discount
accreted to redemption date plus, if applicable, some premium, the amount of
which will decline in subsequent years. "S.F." indicates a sinking
fund is established with respect to an issue of Bonds. 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. For a
general discussion of certain of these events, see "Unitholder
Explanations--Risk Factors" in Part II of this Prospectus. Distributions
will generally be reduced by the amount of the income which would otherwise
have been paid with respect to redeemed Securities and there will be
distributed to Unitholders the principal amount and any premium received on
such redemption. The Estimated Current Return and Estimated Long-Term Return
in this event may be affected by such redemptions. For the Federal tax effect
on Unitholders of such redemptions and resultant distributions, see "
Federal Tax Status" in Part II of this Prospectus.

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

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

Michigan IM-IT Trust--AMBAC Indemnity 17%, Financial Guaranty 34%  and MBIA

The Sponsor may have entered into contracts which hedge interest rate
fluctuations on certain Bonds in certain Portfolios. The cost of any such
contracts and the corresponding gain or loss is included in the Cost to
Sponsor. Certain Securities in the Fund, if any, marked by a double asterisk
(**), have been purchased on a "when, as and if issued" or "
delayed delivery" basis. Interest on these Securities begins accruing to
the benefit of Unitholders on their respective dates of delivery. Delivery is
expected to take place at various dates after the First Settlement Date as
follows:

</TABLE>

On the Date of Deposit, the offering side evaluations of the Securities in the
California IM-IT, Michigan IM-IT and Virginia Quality Trusts were higher than
the bid side evaluations of such Securities by 0.73%, 0.72% and 0.75%,
respectively, of the aggregate principal amounts of such Securities.

"#" indicates that such Bond was issued at an original issue discount.
The tax effect of Bonds issued at an original issue discount is described in
"Federal Tax Status" in Part II of this Prospectus.

(6)This Bond has been purchased at a deep discount from the par value because
there is little or no stated interest income thereon. Bonds which pay no
interest are normally described as "zero coupon" bonds. Over the life
of bonds purchased at a deep discount the value of such bonds will increase
such that upon maturity the holders of such bonds will receive 100% of the
principal amount thereof. To the extent that zero coupon bonds are sold or
called prior to maturity, there is no guarantee that the value of the proceeds
received therefrom by the Trust will equal or exceed the par value that would
have been obtained at maturity of such zero coupon bonds. Approximately 5% of
the aggregate principal amount of the Securities in each of the California
IM-IT Trust and Michigan IM-IT Trust are "zero coupon" bonds. See "
Unitholder Explanations--Settlement of Bonds in the Trusts--Risk Factors" 
in Part II of this Prospectus for a discussion of zero coupon bonds.
    
   
REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

   
To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of Insured Municipals Income Trust and Investors' Quality
Tax-Exempt Trust, Multi-Series 278 (California IM-IT, Michigan IM-IT and
Virginia Quality Trusts):

We have audited the accompanying statements of condition and the related
portfolios of Insured Municipals Income Trust and Investors' Quality
Tax-Exempt Trust, Multi-Series 278 (California IM-IT, Michigan IM-IT and
Virginia Quality Trusts) as of August 15, 1996. The statements of condition
and portfolios are the responsibility of the Sponsor. Our responsibility is to
express an opinion on such financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of irrevocable letters of credit deposited to
purchase tax-exempt securities by correspondence with the Trustee. An audit
also includes assessing the accounting principles used and significant
estimates made by the Sponsor, as well as evaluating the overall financial
statement presentation. We believe our audit provides a reasonable basis for
our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Insured Municipals Income
Trust and Investors' Quality Tax-Exempt Trust, Multi-Series 278 (California
IM-IT, Michigan IM-IT and Virginia Quality Trusts) as of August 15, 1996, in
conformity with generally accepted accounting principles.

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

<F3>The Trustee will advance to the Trust the amount of net interest accrued to
August 20, 1996, the First Settlement Date, for distribution to the Sponsor as
the Unitholder of record as of the First Settlement Date.
    

<F4>The aggregate public offering price (exclusive of interest) and the
aggregate sales charge are computed on the bases set forth under "Unitholder
Explanations--Public Offering--Offering Price" and "Trust
Administration--General--Sponsor and Underwriter Compensation" in Part II
of this Prospectus and assume all single transactions involve less than 100
Units. For single transactions involving 100 or more Units, the sales charge
is reduced (see "Unitholder Explanations--Public Offering--General" in
Part II of this Prospectus) resulting in an equal reduction in both the Cost
to investors and the Gross underwriting commission while the Net interest to
Unitholders remains unchanged.

EQUIVALENT TAXABLE ESTIMATED CURRENT RETURN TABLES

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

* The State tax brackets are those for 1995. The 1996 brackets will be
adjusted to take into account changes in the California Consumer Price Index.
These adjustments have not yet been released. The table reflects a decrease in
State income tax rates for high income taxpayers which is, under current law,
scheduled to take place beginning in 1996.

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
U.S. Government and bank CDs and money market accounts are insured by an
agency of the federal government. Money market accounts and money market funds
provide stability of principal, but pay interest at rates that vary with the
condition of the short-term debt market. The investment characteristics of the
Trusts are described more fully elsewhere in this Prospectus.

ESTIMATED CASH FLOWS TO UNITHOLDERS 

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

Prospectus Part II

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

This Part II of the Prospectus may not be distributed unless accompanied by
Part I. Both Parts of this Prospectus should be retained for future reference.

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

The Fund. The objectives of the Fund are Federal and, in the case of a State
Trust, state tax-exempt income and conservation of capital through an
investment in a diversified portfolio of tax-exempt bonds. The Fund consists
of the underlying separate unit investment trusts set forth in Part I of this
Prospectus. Each Trust initially consists of delivery statements relating to
contracts to purchase securities and, thereafter, will consist of such
securities as may continue to be held (the "Bonds" or "
Securities" ). Such Securities are interest-bearing obligations issued by
or on behalf of municipalities and other governmental authorities, the
interest on which is, in the opinion of recognized bond counsel to the issuing
governmental authority, exempt from all Federal income taxes under the
existing law. In addition, the interest income of each State Trust is, in the
opinion of counsel, exempt to the extent indicated from state and local taxes,
when held by residents of the state where the issuers of Bonds in such Trust
are located. The Bonds in an IM-IT Discount Trust were acquired at prices
which results in an IM-IT Discount Trust portfolio, as a whole, being
purchased at a deep discount from the aggregate par value of such Bonds. Gains
based upon the difference, if any, between the value of the Bonds at maturity,
redemption or sale and their purchase price at a discount (plus earned
original issue discount) will constitute taxable ordinary income with respect
to a Unitholder who is not a dealer with respect to his Units. Except in
specific instances as noted in Part I of this Prospectus, the information
contained in this Part II shall apply to each Trust in its entirety.

"AAA" Rating for the Insured Trusts Only. Insurance guaranteeing the
payments of principal and interest, when due, on the Securities in the
portfolio of each Insured Trust has been obtained from a municipal bond
insurance company either by such Trust or by the issuer of the Bonds involved,
by a prior owner of the Bonds or by the Sponsor prior to the deposit of such
Bonds in an Insured Trust. See "Unitholder Explanations--Insurance on the
Bonds in the Insured Trusts" . Insurance obtained by an Insured Trust
applies only while Bonds are retained in such Trust while insurance obtained
on Preinsured Bonds is effective so long as such Bonds are outstanding. The
Trustee, upon the sale of a Bond insured under an insurance policy obtained by
an Insured Trust, has a right to obtain from the insurer involved permanent
insurance for such Bond upon the payment of a single predetermined insurance
premium and any expenses related thereto from the proceeds of the sale of such
Bond. Insurance relates only to the Bonds in a Trust and not to the Units
offered hereby or to the market value thereof. As a result of such insurance,
the Units of each Insured Trust have received a rating of "AAA" by
Standard & Poor's, A Division of the McGraw-Hill Companies ("Standard &
Poor's" ). Standard & Poor's has indicated that this rating is not a
recommendation to buy, hold or sell Units nor does it take into account the
extent to which expenses of each Insured Trust or sales by each Insured Trust
of Bonds for less than the purchase price paid by such Trust will reduce
payments to Unitholders of the interest and principal required to be paid on
such Bonds. See "Unitholder Explanations--Insurance on the Bonds in the
Insured Trusts" . No representation is made as to any insurer's ability to
meet its commitments.

Units of the Trust are not deposits or obligations of, or guaranteed or
endorsed by, any bank and are not federally insured or otherwise protected by
the Federal Deposit Insurance Corporation, the Federal Reserve Board or any
other agency and involve investment risk, including the possible loss of
principal.

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

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

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

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

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

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

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

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

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

SETTLEMENT OF BONDS IN 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 Part I of this Prospectus. The Fund was created under the laws of
the State of New York pursuant to a Trust Indenture and Agreement (the "
Trust Agreement" ), dated the Date of Deposit, among Van Kampen American
Capital Distributors, Inc., as Sponsor, American Portfolio Evaluation
Services, a division of Van Kampen American Capital Investment Advisory Corp.,
as Evaluator, and The Bank of New York, as Trustee.

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

The portfolio of any IM-IT, IM-IT Discount, State (other than a State
Intermediate Laddered Maturity Trust) 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
dollar-weighted average maturity of the Bonds in any IM-IT Intermediate Trust,
State Intermediate Laddered Maturity Trust and IM-IT Short Intermediate Trust
is less than or equal to 10 years, 10 years and 5 years, respectively.

Substantially all of the Bonds in an IM-IT Discount Trust are obligations
which were originally issued at a discount, including "zero coupon" 
bonds. See "Federal Tax Status" for a discussion of the tax
consequences of original issue discount.

The portfolio of any State Intermediate Laddered Maturity Trust is structured
so that approximately 20% of the Bonds contained in such portfolio will mature
each year, commencing 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 a
State Intermediate Laddered Maturity Trust. However, the flexibility provided
by the return of principal may at the same time eliminate a Unitholder's
ability to reinvest the amount returned at a rate as high as the implicit
yield on the obligations which matured.

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

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

Insurance guaranteeing the timely payment, when due, of all principal and
interest on the Bonds in each Insured Trust has been obtained by such Trust
from either AMBAC Indemnity Corporation ("AMBAC Indemnity" ), Financial
Guaranty Insurance Company ("Financial Guaranty" or "FGIC" ) or
a combination thereof (collectively, the "Portfolio Insurers" ), or by
the issuer of such Bonds, by a prior owner of such Bonds, or by the Sponsor
prior to the deposit of such Bonds in such Trust from certain of the "
Preinsured Bond Insurers" described herein. Insurance obtained by an
Insured Trust is effective only while the Bonds thus insured are held in such
Trust. For information relating to insurance on the bonds, see "Unitholder
Explanations--Insurance on the Bonds in the Insured Trusts." 

In selecting Securities for the Trusts the following factors, among others,
were considered by the Sponsor: (a) either the Standard & Poor's rating of the
Securities was in no case less than "BBB-" in the case of the Insured
Trusts and "A-" in the case of the Quality Trusts, or the Moody's
Investors Service, Inc. ("Moody's" ) rating of the Securities was in no
case less than "Baa" in the case of the Insured Trusts and "A" 
in the case of the Quality Trusts, including provisional or conditional
ratings, respectively, or, if not rated, the Securities had, in the opinion of
the Sponsor, credit characteristics sufficiently similar to the credit
characteristics of interest-bearing tax-exempt obligations that were so rated
as to be acceptable for acquisition by the Fund (see "Description of
Ratings" ), (b) the prices of the Securities relative to other bonds of
comparable quality and maturity, (c) the diversification of Securities as to
purpose of issue and location of issuer and (d) with respect to the Insured
Trusts, the availability and cost of insurance for the prompt payment of
principal and interest, when due, on the Securities. Subsequent to the Date of
Deposit, a Security may cease to be rated or its rating may be reduced below
the minimum required as of the Date of Deposit. Neither event requires
elimination of such Security from the portfolio of a Trust but may be
considered in the Sponsor's determination as to whether or not to direct the
Trustee to dispose of the Security (see "Trust Administration--Fund
Administration and Expenses--Portfolio Administration" ).

Risk Factors. 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. See "
General" for each Trust in Part I of this Prospectus. 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 in the
portfolio 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; 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 the 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 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 of the Bonds may be "zero coupon" bonds. See footnote (6) in
"Notes to Portfolios" in Part I of this Prospectus. 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 footnote (5) in "
Notes to Portfolios" in Part I of this Prospectus. The delivery of any
such Securities may be delayed or may not occur. Interest on these Securities
begins accruing to the benefit of Unitholders on their respective dates of
delivery. To the extent any Securities are actually delivered to the Fund
after their respective expected dates of delivery, Unitholders who purchase
their Units prior to the date such Securities are actually delivered to the
Trustee would be required to adjust their tax basis in their Units for a
portion of the interest accruing on such Securities during the interval
between their purchase of Units and the actual delivery of such Securities. As
a result of any such adjustment, the Estimated Current Returns during the
first year would be slightly lower than those stated herein which would be the
returns after the first year, assuming the portfolio of a Trust and estimated
annual expenses other than that of the Trustee (which may be reduced in the
first year only) do not vary from that set forth under "Per Unit
Information" for the applicable Trust in Part I of this Prospectus.
Unitholders will be "at risk" with respect to all Securities in the
portfolios including "when, as and if issued" and "delayed
delivery" Securities (i.e., may derive either gain or loss from
fluctuations in the evaluation of such Securities) from the date they commit
for Units. For a discussion of the Sponsor's obligations in the event of the
failure of any contract for the purchase of any of the Securities and limited
right to substitute other tax-exempt bonds to replace any failed contract, see
"Replacement Bonds" .

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 "Portfolio" for each Trust and footnote (3)
in the "Notes to Portfolios" in Part I of this Prospectus. 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 Securities which might reasonably be
expected to have a material adverse effect upon the Fund or any of the Trusts.
At any time after the Date of Deposit, litigation may be initiated on a
variety of grounds with respect to Securities in the Fund. Such litigation,
as, for example, suits challenging the issuance of pollution control revenue
bonds under environmental protection statutes, may affect the validity of such
Securities or the tax-free nature of the interest thereon. While the outcome
of litigation of such nature can never be entirely predicted, the Fund has
received or will receive opinions of bond counsel to the issuing authorities
of each Security on the date of issuance to the effect that such Securities
have been validly issued and that the interest thereon is exempt from Federal
income tax. In addition, other factors may arise from time to time which
potentially may impair the ability of issuers to meet obligations undertaken
with respect to the Securities.

Replacement Bonds. Because certain of the Securities in the Fund may from time
to time under certain circumstances be sold or redeemed or will mature in
accordance with their terms and because the proceeds from such events will be
distributed to Unitholders and will not be reinvested, no assurance can be
given that any Trust will retain for any length of time its present size and
composition. Neither the Sponsor nor the Trustee shall be liable in any way
for any default, failure or defect in any Security. In the event of a failure
to deliver any Security that has been purchased for the Fund under a contract,
including those Securities purchased on a "when, as and if issued" 
basis ("Failed Bonds" ), the Sponsor is authorized under the Trust
Agreement to direct the Trustee to acquire other bonds ("Replacement
Bonds" ) to make up the original corpus of the Fund.

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

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

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

Change of Distribution Option. The plan of distribution selected by a
Unitholder will remain in effect until changed. Unitholders purchasing Units
in the secondary market will initially receive distributions in accordance
with the election of the prior owner. Unitholders may change the plan of
distribution in which they are participating. For convenience of Unitholders,
the Trustee will furnish a card for this purpose; cards may also be obtained
upon request from the Trustee. Unitholders desiring to change their plan of
distribution may so indicate on the card and return it together with their
certificate and such other documentation that the Trustee may then require, to
the Trustee. Certificates should only be sent by registered or certified mail
to minimize the possibility of their being lost or stolen. If the card and
certificate are properly presented to the Trustee, the change will become
effective as of the opening of business on the first day after the next
succeeding semi-annual record date and will be effective, unless further
changed, for all subsequent distributions.

Certificates. The Trustee is authorized to treat as the record owner of Units
that person who is registered as such owner on the books of the Trustee.
Ownership of Units of each Trust is evidenced by separate registered
certificates executed by the Trustee and the Sponsor unless a Unitholder or
the Unitholder's registered broker-dealer 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 evidenced as a
certificate, by presentation and surrender of such certificate to the Trustee
properly endorsed or accompanied by a written instrument or instruments of
transfer. A Unitholder must sign such written request, or such certificate
transfer instrument exactly as his name appears on the records of the Trustee,
and on the face of any certificate representing Units to be transferred, with
the signature guaranteed by a participant in the Securities Transfer Agents
Medallion Program ("STAMP" ) or such other signature guaranty program
in addition to, or in substitution for, STAMP, as may be accepted by the
Trustee. In certain instances the Trustee may require additional documents
such as, but not limited to, trust instruments, certificates of death,
appointments as executor or administrator or certificates of corporate
authority. Certificates will be issued in denominations of one Unit or any
multiple thereof. Certificates for Units will bear appropriate notations on
their face indicating which plan of distribution has been selected in respect
thereof. If a change in the plan of distribution is made, the existing
certificate must be surrendered to the Trustee and a new certificate will be
issued, at no charge to the Unitholder, to reflect the currently effective
plan of distribution.

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

ESTIMATED CURRENT RETURNS AND ESTIMATED LONG-TERM RETURNS

As of the close of business on the day before the Date of Deposit (except for
an IM-IT, an IM-IT Discount or a Pennsylvania IM-IT Trust as of 8:00 A.M.
Central Time on the Date of Deposit) the Estimated Current Returns and the
Estimated Long-Term Returns, under the monthly and semi-annual distribution
plans, were as set forth in the "Per Unit Information" for each Trust
in Part I of this Prospectus. Estimated Current Return is calculated by
dividing the estimated net annual interest income per Unit by the Public
Offering Price. The estimated net annual interest income per Unit will vary
with changes in fees and expenses of the Trustee and the Evaluator and with
the principal prepayment, redemption, maturity, exchange or sale of Securities
while the Public Offering Price will vary with changes in the offering price
of the underlying Securities; therefore, there is no assurance that the
present Estimated Current Return will be realized in the future. Estimated
Long-Term Return is calculated using a formula which (1) takes into
consideration, and determines and factors in the relative weightings of, the
market values, yields (which takes into account the amortization of premiums
and the accretion of discounts) and estimated retirements of all of the
Securities in a Trust and (2) takes into account the expenses and sales charge
associated with each Trust Unit. Since the market values and estimated
retirements of the Securities and the expenses of a Trust will change, there
is no assurance that the present Estimated Long-Term Return will be realized
in the future. The Estimated Current Return and Estimated Long-Term Return are
expected to differ because the calculation of Estimated Long-Term Return
reflects the estimated date and amount of principal returned while the
Estimated Current Return calculation includes only net annual interest income
and Public Offering Price.

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

ACCRUED INTEREST

Accrued interest is an accumulation of unpaid interest on securities which
generally is paid semi-annually, although each Trust accrues such 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 subsequent to the First Settlement Date, the Public Offering Price of
Units will have added to it the proportionate share of accrued interest to the
date of settlement. Unitholders will receive on the next distribution date of
a Trust the amount, if any, of accrued interest paid on their Units.

In an effort to reduce the amount of accrued interest which would otherwise
have to be paid by Unitholders, the Trustee will advance the amount of accrued
interest to the Sponsor as the Unitholder of record as of the First Settlement
Date. Consequently, the amount of accrued interest to be added to the Public
Offering Price of Units will include only accrued interest from the First
Settlement Date to the date of settlement, less any distributions from the
Interest Account subsequent to the First Settlement Date. See "Public
Offering--Distributions of Interest and Principal." 

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

PUBLIC OFFERING

General. Units are offered at the Public Offering Price. During the initial
offering period the Public Offering Price is based on the aggregate offering
price of the Securities in such Trust's portfolio, a sales charge of 4.9% of
the Public Offering Price (5.152% of the aggregate offering price of the
Securities) for an IM-IT, a State (other than a State Intermediate Laddered
Maturity Trust) or a National Quality Trust, 4.3% of the Public Offering Price
(4.493% of the aggregate offering price of the Securities) for an IM-IT
Limited Maturity Trust, 4.0% of the Public Offering Price (4.167% of the
aggregate offering price of the Securities) for an IM-IT Discount Trust, 3.9%
of the Public Offering Price (4.058% of the aggregate offering price of the
Securities) for an IM-IT Intermediate Trust, 3.0% of the Public Offering Price
(3.093% of the aggregate offering price of the Securities) for a State
Intermediate Laddered Maturity Trust and 2.0% of the Public Offering Price
(2.041% of the aggregate offering price of the Securities) for an IM-IT Short
Intermediate Trust, cash, if any, in the Principal Account held or owned by
such Trust, and accrued interest, if any. After the initial public offering
period, the secondary market public offering price is based on the bid prices
of the Securities in each Trust, an applicable sales charge as determined in
accordance with the table set forth below, which is based upon the estimated
long-term return life of each Trust, cash, if any, in the Principal Account
held or owned by such Trust, and accrued interest, if any. For purposes of
computation, Bonds will be deemed to mature on their expressed maturity dates
unless: (a) the Bonds have been called for redemption or are subject to
redemption at an earlier call date, in which case such call date will be
deemed to be the date upon which they mature; or (b) such Bonds are subject a
"mandatory tender" , in which case such mandatory tender will be deemed
to be the date upon which they mature. 

The effect of this method of sales charge computation will be that different
sales charge rates will be applied to each Trust based upon the estimated
long-term return life of such Trust's Portfolio, in accordance with the
following schedule: 

<TABLE>

11                   4.603
</TABLE>

The sales charges in the above table are expressed as a percentage of the
aggregate bid prices of the Securities in a Trust. Expressed as a percent of
the Public Offering Price, the sales charge on a Trust consisting entirely of
a portfolio 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 Part I of any Prospectus by which such Trust is offered. The sales
charge applicable to quantity purchases during the initial offering period is,
however, reduced on a graduated basis to any person acquiring 100 or more
Units as follows:

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

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

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

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

The aggregate price of the Securities in each Trust has been and will be
determined on the basis of bid prices or offering prices, as is appropriate,
(a) on the basis of current market prices for the Securities obtained from
dealers or brokers who customarily deal in bonds comparable to those held by
the Fund; (b) if such prices are not available for any particular Securities,
on the basis of current market prices for comparable bonds; (c) by causing the
value of the Securities to be determined by others engaged in the practice of
evaluation, quoting or appraising comparable bonds; or (d) by any combination
of the above. Market prices of the Securities will generally fluctuate with
changes in market interest rates. Unless Bonds are in default in payment of
principal or interest or in significant risk of such default, the Evaluator
will not attribute any value to the insurance obtained by an Insured Trust, if
any.

The Evaluator will consider in its evaluation of Bonds which are in default in
payment of principal or interest or, in the Sponsor's opinion, in significant
risk of such default (the "Defaulted Bonds" ) the value of the
insurance guaranteeing interest and principal payments. The value of the
insurance will be equal to the difference between (i) the market value of
Defaulted Bonds assuming the exercise of the right to obtain Permanent
Insurance (less the insurance premiums and related expenses attributable to
the purchase of Permanent Insurance) and (ii) the market value of such
Defaulted Bonds not covered by Permanent Insurance. In addition, the Evaluator
will consider the ability of the affected Portfolio Insurer to meet its
commitments under any Trust insurance policy, including the commitments to
issue Permanent Insurance. It is the position of the Sponsor that this is a
fair method of valuing the Bonds and the insurance obtained by an Insured
Trust and reflects a proper valuation method in accordance with the provisions
of the Investment Company Act of 1940. No value has been ascribed to insurance
obtained by an Insured Trust, if any, as of the date of this Prospectus.

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

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

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

Distributions of Interest and Principal. Interest received by the Fund,
including that part of the proceeds of any disposition of Securities which
represents accrued interest, is credited by the Trustee to the Interest
Account for the appropriate Trust. Other receipts are credited to the
Principal Account for the appropriate Trust. Interest received by the Fund
after deduction of amounts sufficient to reimburse the Trustee, without
interest, for any amounts advanced and paid to the Sponsor as the Unitholder
of record as of the First Settlement Date (see "Public Offering--Offering
Price" above) will be distributed on or shortly after the twenty-fifth day
of each month on a pro rata basis to Unitholders of record of a Trust as of
the preceding record date who are entitled to distributions at that time under
the plan of distributions chosen. All distributions will be net of applicable
expenses. The pro rata share of cash in the Principal Account of a Trust will
be computed as of the date set forth under "Per Unit Information" for
the applicable Trust in Part I of this Prospectus, and thereafter as of the
semi-annual record date, and distributions to the Unitholders as of such
record date will be made on or shortly after the twenty-fifth day of such
month. Proceeds received from the disposition of any of the Securities after
such record date and prior to the following distribution date will be held in
the Principal Account and not distributed until the next distribution date.
The Trustee is not required to pay interest on funds held in any Principal or
Interest Account (but may itself earn interest thereon and therefore benefits
from the use of such funds) nor to make a distribution from the Principal
Account unless the amount available for distribution therein shall equal at
least $1.00 per Unit. However, should the amount available for distribution in
the Principal Account equal or exceed $10.00 per Unit, the Trustee will make a
special distribution from the Principal Account on the next succeeding monthly
distribution date to holders of record on the related monthly record date.

The distribution to the Unitholders of a Trust as of each record date after
the First Settlement Date will be made on the following distribution date or
shortly thereafter and shall consist of an amount substantially equal to such
portion of the Unitholder's pro rata share of the estimated net annual
interest income in the Interest Account of such Trust after deducting
estimated expenses attributable as is consistent with the distribution plan
chosen. Because interest payments are not received by the Fund at a constant
rate throughout the year, such interest distribution may be more or less than
the amount credited to such Interest Account as of the record date. For the
purpose of minimizing fluctuations in the distributions from an Interest
Account, the Trustee is authorized to advance such amounts as may be necessary
to provide interest distributions of approximately equal amounts. The Trustee
shall be reimbursed for any such advances from funds in the applicable
Interest Account on the ensuing record date. Persons who purchase Units
between a record date and a distribution date will receive their first
distribution on the second distribution date after the purchase, under the
applicable plan of distribution.

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 (as
determined on the basis set forth under "Trust Administration--Fund
Administration and Expenses" ). The Trustee also may withdraw from said
Accounts such amounts, if any, as it deems necessary to establish a reserve
for any governmental charges payable out of the Fund. Amounts so withdrawn
shall not be considered a part of the Fund's assets until such time as the
Trustee shall return all or any part of such amounts to the appropriate
Accounts. In addition, the Trustee may withdraw from the Interest and
Principal Accounts such amounts as may be necessary to cover purchases of
Replacement Bonds and redemptions of Units by the Trustee.

Reinvestment Option. Unitholders of unit investment trusts sponsored by Van
Kampen American Capital Distributors, Inc., may elect to have each
distribution of interest income, capital gains and/or principal on their Units
automatically reinvested in shares of any Van Kampen American Capital mutual
funds (except for B shares) which are registered in the Unitholder's state of
residence. Such mutual funds are hereinafter collectively referred to as the
"Reinvestment Funds" .

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

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

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

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

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

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

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

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

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

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

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

INSURANCE ON THE BONDS IN THE INSURED TRUSTS

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

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

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

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

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

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

</TABLE>

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 Securities in such portfolio had Standard & Poor's "AAA" rating
and yet at the same time to have the protection of insurance of prompt payment
of interest and principal, when due, on the Bonds. There is, of course, no
certainty that this result will be achieved. Preinsured Bonds in an Insured
Trust (all of which are rated "AAA" by Standard & Poor's) may or may
not have a higher yield than uninsured bonds rated "AAA" by Standard &
Poor's. In selecting such Bonds for an Insured Trust, the Sponsor has applied
the criteria hereinbefore described.

In the event of nonpayment of interest or principal, when due, in respect of a
Bond, AMBAC Indemnity shall make such payment not later than 30 days and
Financial Guaranty shall make such payment within one business day after the
respective insurer has been notified that such nonpayment has occurred or is
threatened (but not earlier than the date such payment is due). The insurer,
as regards any payment it may make, will succeed to the rights of the Trustee
in respect thereof. All policies issued by the Portfolio Insurers and the
Preinsured Bond Insurers are substantially identical insofar as obligations to
an Insured Trust are concerned.

The Internal Revenue Service has issued a letter ruling which holds in effect
that insurance proceeds representing maturing interest on defaulted municipal
obligations paid to holders of insured bonds, under policy provisions
substantially identical to the policies described herein, will be excludable
from Federal gross income under Section 103(a)(1) of the Internal Revenue Code
to the same extent as if such payments were made by the issuer of the
municipal obligations. Holders of Units in an Insured Trust should discuss
with their tax advisers the degree of reliance which they may place on this
letter ruling. However, Chapman and Cutler, counsel for the Sponsor, has given
an opinion to the effect such payment of proceeds would be excludable from
Federal gross income to the extent described under "Federal Tax Status" 
 .

Each Portfolio Insurer is subject to regulation by the department of insurance
in the state in which it is qualified to do business. Such regulation,
however, is no guarantee that each Portfolio Insurer will be able to perform
on its contract of insurance in the event a claim should be made thereunder at
some time in the future. At the date hereof, it is reported that no claims
have been submitted or are expected to be submitted to any of the Portfolio
Insurers which would materially impair the ability of any such company to meet
its commitment pursuant to any contract of bond or portfolio insurance.

The information relating to each Portfolio Insurer has been furnished by such
companies. The financial information with respect to each Portfolio Insurer
appears in reports filed with state insurance regulatory authorities and is
subject to audit and review by such authorities. No representation is made
herein as to the accuracy or adequacy of such information or as to the absence
of material adverse changes in such information subsequent to the dates
thereof.

For information relating to the insurance on the Bonds in the Insured Trusts
and the breakdown of the insurers of Preinsured Bonds, see footnote (5) in
"Notes to Portfolios" in Part I of this Prospectus.

UNDERWRITING

For a breakdown of the Underwriters who have severally purchased Units of each
Trust from the Sponsor, see "Other Matters--Underwriting" in Part I of
this Prospectus.

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

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

Underwriters and broker-dealers of the Trusts, banks and/or others are
eligible to participate in a program in which such firms receive from the
Sponsor a nominal award for each of their representatives who have sold a
minimum number of units of unit investment trusts created by the Sponsor
during a specified time period. In addition, at various times the Sponsor may
implement other programs under which the sales forces of Underwriters,
brokers, dealers, banks and/or others may be eligible to win other nominal
awards for certain sales efforts, or under which the Sponsor will reallow to
any such Underwriters, brokers, dealers, banks and/or others that sponsor
sales contests or recognition programs conforming to criteria established by
the Sponsor, or participate in sales programs sponsored by the Sponsor, an
amount not exceeding the total applicable sales charges on the sales generated
by such persons at the public offering price during such programs. Also, the
Sponsor in its discretion may from time to time pursuant to objective criteria
established by the Sponsor pay fees to qualifying underwriters, brokers,
dealers, banks or others for certain services or activities which are
primarily intended to result in sales of Units of the Trusts. Such payments
are made by the Sponsor out of its own assets, and not out of the assets of
the Trusts. These programs will not change the price Unitholders pay for their
Units or the amount that the Trusts will receive from the Units sold.
Approximately every eighteen months the Sponsor holds a business seminar which
is open to Underwriters that sell units of trusts it sponsors. The Sponsor
pays substantially all costs associated with the seminar, excluding
Underwriter travel costs. Each Underwriter is invited to send a certain number
of representatives based on the gross number of units such firm underwrites
during a designated time period.

FUND ADMINISTRATION AND EXPENSES

Sponsor. Van Kampen American Capital Distributors, Inc., a Delaware
corporation, is the Sponsor of the Trust. Van Kampen American Capital
Distributors, Inc. is primarily owned by Clayton, Dubilier & Rice, Inc., a New
York-based private investment firm. Van Kampen American Capital Distributors,
Inc. management owns a significant minority equity position. On June 21, 1996
VK/AC Holding, Inc., the indirect corporate parent of the Sponsor, entered
into an Agreement and Plan of Merger among Morgan Stanley Group Inc., MSAM
Holdings II, Inc. and MSAM Acquisition Inc., pursuant to which MSAM
Acquisition Inc. will be merged with and into VK/AC Holding, Inc. and VK/AC
Holding, Inc. will be the surviving corporation. MSAM Acquisition Inc. is a
wholly owned subsidiary of MSAM Holdings II, Inc. which, in turn, is a wholly
owned subsidiary of Morgan Stanley Group Inc. Subject to a number of
conditions being met, it is currently anticipated that a closing will occur in
November of 1996. Thereafter, VK/AC Holding, Inc. and its affiliated entities,
including the Sponsor, shall be part of the Morgan Stanley Group Inc. Van
Kampen American Capital Distributors, Inc. specializes in the underwriting and
distribution of unit investment trusts and mutual funds with roots in money
management dating back to 1926. The Sponsor is a member of the National
Association of Securities Dealers, Inc. and has offices at One Parkview Plaza,
Oakbrook Terrace, Illinois 60181, (708) 684-6000 and 2800 Post Oak Boulevard,
Houston, Texas, 77056, (713) 993-0500. It maintains a branch office in
Philadelphia and has regional representatives in Atlanta, Dallas, Los Angeles,
New York, San Francisco, Seattle and Tampa. As of March 31, 1996 the total
stockholders' equity of Van Kampen American Capital Distributors, Inc. was
$123,020,000 (unaudited). (This paragraph relates only to the Sponsor and not
to the Fund or to any Series thereof or to any other Underwriter. The
information is included herein only for the purpose of informing investors as
to the financial responsibility of the Sponsor and its ability to carry out
its contractual obligations. More detailed financial information will be made
available by the Sponsor upon request.)

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

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

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

Compensation of Sponsor and Evaluator. The Sponsor will not receive any fees
in connection with its activities relating to the Fund. However, American
Portfolio Evaluation Services, a division of Van Kampen American Capital
Investment Advisory Corp., which is an affiliate of the Sponsor, will receive
an annual supervisory fee as indicated under "Summary of Essential
Financial Information" in Part I of this Prospectus for providing
portfolio supervisory services for the Fund. Such fee may exceed the actual
costs of providing such supervisory services for this Fund, but at no time
will the total amount received for portfolio supervisory services rendered to
Series 1 of the Fund and subsequent series and to any other unit investment
trusts sponsored by the Sponsor for which the Evaluator provides portfolio
supervisory services in any calendar year exceed the aggregate cost to the
Evaluator of supplying such services in such year. In addition, the Evaluator
shall receive an annual evaluation fee as indicated under "Summary of
Essential Financial Information" in Part I of this Prospectus for
regularly evaluating each Trust's portfolio. Such fees are based on the
outstanding principal amount of Securities in each Trust on the Date of
Deposit for the first year and as of the close of business on January 1 for
each year thereafter. Both of the foregoing fees may be increased without
approval of the Unitholders by amounts not exceeding proportionate increases
under the category "All Services Less Rent of Shelter" in the Consumer
Price Index published by the United States Department of Labor or, if such
category is no longer published, in a comparable category. The Sponsor and the
Underwriters will receive sales commissions and may realize other profits (or
losses) in connection with the sale of Units and the deposit of the Securities
as described under "General--Sponsor and Underwriter Compensation" 
below.

Trustee. The Trustee is The Bank of New York, a trust company organized under
the laws of New York. The Bank of New York has its 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 (see "Unitholder Explanations--Public Offering--Reports
Provided" ). The Trustee is required to keep a certified copy or duplicate
original of the Trust Agreement on file in its office available for inspection
at all reasonable times during the usual business hours by any Unitholder,
together with a current list of the Securities held in the Fund.

Under the Trust Agreement, the Trustee or any successor trustee may resign and
be discharged of the trusts created by the Trust Agreement by executing an
instrument in writing and filing the same with the Sponsor. The Trustee or
successor trustee must mail a copy of the notice of resignation to all Fund
Unitholders then of record, not less than 60 days before the date specified in
such notice when such resignation is to take effect. The Sponsor upon
receiving notice of such resignation is obligated to appoint a successor
trustee promptly. If, upon such resignation, no successor trustee has been
appointed and has accepted the appointment within 30 days after notification,
the retiring Trustee may apply to a court of competent jurisdiction for the
appointment of a successor. The Sponsor may remove the Trustee and appoint a
successor trustee as provided in the Trust Agreement at any time with or
without cause. Notice of such removal and appointment shall be mailed to each
Unitholder by the Sponsor. Upon execution of a written acceptance of such
appointment by such successor trustee, all the rights, powers, duties and
obligations of the original trustee shall vest in the successor. The
resignation or removal of a Trustee becomes effective only when the successor
trustee accepts its appointment as such or when a court of competent
jurisdiction appoints a successor trustee. Any corporation into which a
Trustee may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which a Trustee shall be a
party, shall be the successor trustee. The Trustee must be a banking
corporation organized under the laws of the United States or any state and
having at all times an aggregate capital, surplus and undivided profits of not
less than $5,000,000.

Trustee's Fee. For its services the Trustee will receive a fee based on the
aggregate outstanding principal amount of Securities in each Trust as of the
opening of business on January 2 and July 2 of each year as set forth under
"Per Unit Information" for the applicable Trust in Part I of this
Prospectus. During the first year the Trustee may agree to reduce its fee (and
to the extent necessary pay miscellaneous expenses of a Trust) as stated under
"Per Unit Information" for the applicable Trust in Part I of this
Prospectus. After the first year such fee will be computed at $.51 per $1,000
principal amount of Securities for that portion of each Trust under the
semi-annual distribution plan and $.91 per $1,000 principal amount of
Securities for that portion of each Trust under the monthly distribution plan.
Based on the size of the Trust on the Date of Deposit, the Trustee's estimated
annual fees for ordinary recurring services would initially amount to that
amount set forth under "Per Unit Information" for the applicable Trust
in Part I of the Prospectus. The Trustee's fees are payable monthly on or
before the twenty-fifth day of each month from the Interest Account of each
Trust to the extent funds are available and then from the Principal Account of
each Trust, with such payments being based on each Trust's portion of such
expenses. Since the Trustee has the use of the funds being held in the
Principal and Interest Accounts for future distributions, payment of expenses
and redemptions and since such Accounts are non-interest bearing to
Unitholders, the Trustee benefits thereby. Part of the Trustee's compensation
for its services to each Trust is expected to result from the use of these
funds. Such fees may be increased without approval of the Unitholders by
amounts not exceeding proportionate increases under the category "All
Services Less Rent of Shelter" in the Consumer Price Index published by
the United States Department of Labor or, if such category is no longer
published, in a comparable category. The Trustee's fees will not be increased
in future years in order to make up any reduction in the Trustee's fees
described under "Per Unit Information" for the applicable Trust in
Part I of this Prospectus. For a discussion of the services rendered by the
Trustee pursuant to its obligations under the Trust Agreement, see "
Unitholder Explanations--Public Offering--Reports Provided" and "
Trustee" above.

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

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

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

Sponsor Purchases of Units. The Trustee shall notify the Sponsor of any tender
of Units for redemption. If the Sponsor's bid in the secondary market at that
time equals or exceeds the Redemption Price per Unit, it may purchase such
Units by notifying the Trustee before the close of business on the second
succeeding business day and by making payment therefor to the Unitholder not
later than the day on which the Units would otherwise have been redeemed by
the Trustee. Units held by the Sponsor may be tendered to the Trustee for
redemption as any other Units. The offering price of any Units acquired by the
Sponsor will be in accord with the Public Offering Price described in the then
currently effective prospectus describing such Units. Any profit resulting
from the resale of such Units will belong to the Sponsor which likewise will
bear any loss resulting from a lower offering or Redemption Price subsequent
to its acquisition of such Units.

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

Miscellaneous Expenses. The following additional charges are or may be
incurred by the Trusts: (a) fees of the Trustee for extraordinary services,
(b) expenses of the Trustee (including legal and auditing expenses) and of
counsel designated by the Sponsor, (c) various governmental charges, (d)
expenses and costs of any action taken by the Trustee to protect the Trusts
and the rights and interests of Unitholders, (e) indemnification of the
Trustee for any loss, liability or expenses incurred by it in the
administration of the Fund without negligence, bad faith or willful misconduct
on its part, (f) any special custodial fees payable in connection with the
sale of any of the Bonds in a Trust, (g) expenditures incurred in contacting
Unitholders upon termination of the Trusts and (h) costs incurred to reimburse
the Trustee for advancing funds to the Trusts to meet scheduled distributions
(which costs may be adjusted periodically in response to fluctuations in
short-term interest rates). The fees and expenses set forth herein are payable
out of the Trusts. When such fees and expenses are paid by or owing to the
Trustee, they are secured by a lien on the portfolio or portfolios of the
applicable Trust or Trusts. If the balances in the Interest and Principal
Accounts are insufficient to provide for amounts payable by the Fund, the
Trustee has the power to sell Securities to pay such amounts.

GENERAL

Amendment or Termination. The Sponsor and the Trustee have the power to amend
the Trust Agreement without the consent of any of the Unitholders when such an
amendment is (a) to cure an ambiguity or to correct or supplement any
provision of the Trust Agreement which may be defective or inconsistent with
any other provision contained therein or (b) to make such other provisions as
shall not adversely affect the interest of the Unitholders (as determined in
good faith by the Sponsor and the Trustee), provided that the Trust Agreement
may not be amended to increase the number of Units issuable thereunder or to
permit the deposit or acquisition of securities either in addition to or in
substitution for any of the Securities initially deposited in the Fund, except
for the substitution of certain refunding securities for such Securities. In
the event of any amendment, the Trustee is obligated to notify promptly all
Unitholders of the substance of such amendment.

A Trust may be terminated at any time by consent of Unitholders of 51% of the
Units of such Trust then outstanding or by the Trustee when the value of such
Trust, as shown by any semi-annual evaluation, is less than that indicated
under "Summary of Essential Financial Information" in Part I of this
Prospectus. A Trust will be liquidated by the Trustee in the event that a
sufficient number of Units not yet sold are tendered for redemption by the
Underwriters, including the Sponsor, so that the net worth of such Trust would
be reduced to less than 40% of the initial principal amount of such Trust. If
a Trust is liquidated because of the redemption of unsold Units by the
Underwriters, the Sponsor will refund to each purchaser of Units the entire
sales charge paid by such purchaser. The Trust Agreement provides that each
Trust shall terminate upon the redemption, sale or other disposition of the
last Security held in such Trust, but in no event shall it continue beyond the
end of the year preceding the fiftieth anniversary of the Trust Agreement in
the case of an IM-IT, an IM-IT Discount, a State (other than a State
Intermediate Laddered Maturity Trust) or a National Quality Trust, or beyond
the end of the year preceding the twentieth anniversary of the Trust Agreement
in the case of IM-IT Limited Maturity, IM-IT Intermediate, State Intermediate
Laddered Maturity and IM-IT Short Intermediate Trusts. In the event of
termination of the Fund or any Trust, written notice thereof will be sent by
the Trustee to each Unitholder of such Trust at his address appearing on the
registration books of the Fund maintained by the Trustee. Within a reasonable
time thereafter the Trustee shall liquidate any Securities then held in such
Trust and shall deduct from the funds of such Trust any accrued costs,
expenses or indemnities provided by the Trust Agreement, including estimated
compensation of the Trustee and costs of liquidation and any amounts required
as a reserve to provide for payment of any applicable taxes or other
governmental charges. The sale of Securities in the Trust upon termination may
result in a lower amount than might otherwise be realized if such sale were
not required at such time. For this reason, among others, the amount realized
by a Unitholder upon termination may be less than the principal amount or par
amount of Securities represented by the Units held by such Unitholder. The
Trustee shall then distribute to each Unitholder his share of the balance of
the Interest and Principal Accounts. With such distribution the Unitholder
shall be furnished a final distribution statement of the amount distributable.
At such time as the Trustee in its sole discretion shall determine that any
amounts held in reserve are no longer necessary, it shall make distribution
thereof to Unitholders in the same manner.

Notwithstanding the foregoing, in connection with final distributions to
Unitholders of an Insured Trust, it should be noted that because the portfolio
insurance obtained by an Insured Trust is applicable only while Bonds so
insured are held by such Trust, the price to be received by such Trust upon
the disposition of any such Bond which is in default, by reason of nonpayment
of principal or interest, will not reflect any value based on such insurance.
Therefore, in connection with any liquidation, it shall not be necessary for
the Trustee to, and the Trustee does not currently intend to, dispose of any
Bond or Bonds if retention of such Bond or Bonds, until due, shall be deemed
to be in the best interest of Unitholders, including, but not limited to,
situations in which a Bond or Bonds so insured are in default and situations
in which a Bond or Bonds so insured have deteriorated market prices resulting
from a significant risk of default. Since the Preinsured Bonds will reflect
the value of the related insurance, it is the present intention of the Sponsor
not to direct the Trustee to hold any of such Preinsured Bonds after the date
of termination. All proceeds received, less applicable expenses, from
insurance on defaulted Bonds not disposed of at the date of termination will
ultimately be distributed to Unitholders of record as of such date of
termination as soon as practicable after the date such defaulted Bond or Bonds
become due and applicable insurance proceeds have been received by the Trustee.

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

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

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

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

The Sponsor intends to qualify the Units for sale in a number of states.
Broker-dealers or others will be allowed a concession or agency commission in
connection with the distribution of Units during the initial offering period
of $10.00 per Unit for less than 100 Units, $10.00 per Unit for any single
transaction of 100 to 249 Units, $9.50 per Unit for any single transaction of
250 to 499 Units, $9.00 per Unit for any single transaction of 500 to 999
Units and $8.00 per Unit for any single transaction of 1,000 or more Units of
an IM-IT Short Intermediate Trust, $25.00 per Unit for less than 100 Units,
$29.00 per Unit for any single transaction of 100 to 249 Units, $28.50 per
Unit for any single transaction of 250 to 499 Units, $31.50 per Unit for any
single transaction of 500 to 999 Units and $31.00 per Unit for any single
transaction of 1,000 or more Units of an IM-IT Intermediate Trust, $27.00 per
Unit for less than 100 Units, $31.00 per Unit for any single transaction of
100 to 249 Units, $30.50 per Unit for any single transaction of 250 to 499
Units, $33.50 per Unit for any single transaction of 500 to 999 Units and
$31.00 per Unit for any single transaction of 1,000 or more Units of an IM-IT
Limited Maturity Trust, $18.00 per Unit for less than 100 Units, $18.00 per
Unit for any single transaction of 100 to 249 Units, $16.00 per Unit for any
single transaction of 250 to 499 Units, $14.00 per Unit for any single
transaction of 500 to 999 Units, $12.00 per Unit for any single transaction of
1,000 to 1,499 Units, and $10.00 per Unit for any single transaction of 1,500
or more Units of an IM-IT Discount Trust, $20.00 per Unit for less than 100
Units, $22.00 per Unit for any single transaction of 100 to 249 Units, $21.50
per Unit for any single transaction of 250 to 499 Units, $24.50 per Unit for
any single transaction of 500 to 999 Units and $24.00 per Unit for any single
transaction of 1,000 or more Units of a State Intermediate Laddered Maturity
Trust, and in the case of an IM-IT, a State (other than a State Intermediate
Laddered Maturity Trust) or a National Quality Trust $30.00 per Unit for less
than 100 Units, $36.00 per Unit for any single transaction of 100 to 249
Units, $38.00 per Unit for any single transaction of 250 to 499 Units, $39.00
per Unit for any single transaction of 500 to 999 Units and $39.00 per Unit
for any single transaction of 1,000 or more Units, provided that such Units
are acquired either from the Sponsor (in the case of dealer transactions) or
through the Sponsor (in the case of transactions involving brokers or others).
The increased concession or agency commission is a result of the discount
given to purchasers for quantity purchases. See "Unitholder
Explanations--Public Offering--General" . Certain commercial banks are
making Units of the Fund available to their customers on an agency basis. A
portion of the sales charge paid by these customers (equal to the agency
commission referred to above) is retained by or remitted to the banks. Under
the Glass-Steagall Act, banks are prohibited from underwriting Units of the
Fund; however, the Glass-Steagall Act does permit certain agency transactions
and the banking regulators have not indicated that these particular agency
transactions are not permitted under such Act. In addition, state securities
laws on this issue may differ from the interpretations of federal law
expressed herein and banks and financial institutions may be required to
register as dealers pursuant to state law. Any quantity discount (see "
Unitholder Explanations--Public Offering--General" ) provided to investors
will be borne by the selling dealer or agent. For secondary market
transactions, such concession or agency commission will amount to 70% of the
applicable sales charge as determined using the table found in "Unitholder
Explanations--Public Offering" . The minimum purchase in the primary and
secondary market will be one Unit. The Sponsor reserves the right to reject,
in whole or in part, any order for the purchase of Units and to change the
amount of the concession or agency commission to dealers and others from time
to time. See "Unitholder Explanations--Underwriting" herein and "
Other Matters--Underwriting" in Part I of this Prospectus.

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

The Sponsor will receive from the Underwriters the excess of such gross sales
commission over $35.00, $20.00, $29.00, $27.00, $12.00, $22.00 and $35.00 per
Unit of any Quality, IM-IT Discount, IM-IT Limited Maturity, IM-IT
Intermediate, IM-IT Short Intermediate, State Intermediate Laddered Maturity
Trust and any Insured Trusts, respectively, as of the Date of Deposit. In
connection with quantity sales to purchasers of any IM-IT Discount Trust the
Underwriters will receive from the Sponsor commissions totaling $19.00 per
Unit for any single transaction of 100 to 249 Units, $18.00 per Unit for any
single transaction of 250 to 499 Units, $16.00 per Unit for any single
transaction of 500 to 999 Units, $14.00 per Unit for any single transaction of
1,000 to 1,499 Units, and $12.00 per Unit for any single transaction of 1,500
or more Units. In connection with quantity sales to purchasers of any IM-IT,
State Trust (other than a State Intermediate Laddered Maturity Trust) or
National Quality Trust the Underwriters will receive from the Sponsor
commissions totalling $37.00 per Unit for any single transaction of 100 to 249
Units, $39.00 per Unit for any single transaction of 250 to 499 Units, $40.00
per Unit for any single transaction of 500 to 999 Units and $39.00 per Unit
for any single transaction of 1,000 or more Units. In connection with quantity
sales to purchasers of any IM-IT Short Intermediate Trust the Underwriters
will receive from the Sponsor commissions totalling $11.00 per Unit for any
single transaction of 100 to 249 Units, $10.50 per Unit for any single
transaction to 250 to 499 Units, $10.00 per Unit for any single transaction of
500 to 999 Units and $8.00 per Unit for any single transaction of 1,000 or
more Units. In connection with quantity sales to purchasers of any IM-IT
Intermediate Trust the Underwriters will receive from the Sponsor commissions
totalling $30.00 per Unit for any single transaction of 100 to 249 Units,
$29.50 per Unit for any single transaction of 250 to 499 Units, $32.50 per
Unit for any single transaction of 500 to 999 Units and $31.00 per Unit for
any single transaction of 1,000 or more Units. In connection with quantity
sales to purchasers of any IM-IT Limited Maturity Trust the Underwriters will
receive from the Sponsor commissions totalling $32.00 per Unit for any single
transaction of 100 to 249 Units, $32.00 per Unit for any single transaction of
250 to 499 Units, $34.50 per Unit for any single transaction of 500 to 999
Units and $31.00 per Unit for any single transaction of 1,000 or more Units.
In connection with quantity sales to purchasers of any State Intermediate
Laddered Maturity Trust the Underwriters will receive from the Sponsor
commissions totalling $23.00 per Unit for any single transaction of 100 to 249
Units, $23.00 per Unit for any single transaction of 250 to 499 Units, $24.75
per Unit for any single transaction of 500 to 999 Units and $24.00 per Unit
for any single transaction of 1,000 or more Units. 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. Also, if Principal
Financial Securities, Inc. commits (on the Date of Deposit) to underwrite a
total of 4,000 or more Units of a single series of the IM-IT, any other series
of the IM-IT and/or any series of Texas Insured Municipals Income Trust during
any calendar month, then Principal Financial Securities, Inc. will receive an
additional $1.00 per Unit for each of the Units of such Trust it commits to
underwrite in said month. In addition, the Sponsor will receive from the
Managing Underwriters of any National Quality, California IM-IT, Connecticut
IM-IT, Massachusetts IM-IT, Michigan IM-IT, New York IM-IT, Oklahoma IM-IT,
Ohio IM-IT, Kansas Quality, Maryland Quality or Oregon Quality Trust (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 addition, the Sponsor will receive from the Managing
Underwriters of the Florida IM-IT Intermediate Laddered Maturity Trust (who

that sells a total of 25% or 1,500 Units, whichever is greater, of any
individual series of such Trust will receive an additional $1.00 per each such
Unit. In connection with quantity sales to purchasers of any Pennsylvania

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

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.
The Sponsor and First Investors Corporation ("First Investors" ) have
entered into an agreement under which First Investors will receive an
additional $5.00 per Unit in connection with a minimum commitment of 17.5% of
the total Units of the New York IM-IT Trust, provided that the New York IM-IT
Trust does not exceed 10,000 Units. If the New York IM-IT Trust exceeds 10,000
Units, First Investors will receive an additional $5.00 per Unit if First
Investors underwrites the lesser of 3,000 Units or 20% of the New York IM-IT
Trust. In addition, the Sponsor has entered into agreements with Advest, Inc.

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. See
"Unitholder Explanations--Public Offering--General." Further, each
Underwriter who underwrites 1,000 or more Units in any Trust will receive
additional compensation from the Sponsor of $1.00 for each Unit it
underwrites. In addition, the Sponsor and certain of the Underwriters will
realize a profit or the Sponsor will sustain a loss, as the case may be, as a
result of the difference between the price paid for the Securities by the
Sponsor and the cost of such Securities to a Trust (which is based on the
determination by Interactive Data Corporation of the aggregate offering price
of the underlying Securities in such Trust on the Date of Deposit). See "
Unitholder Explanations--Underwriting" herein and "Portfolio" for
the applicable Trust and "Notes to Portfolios" in Part I of this
Prospectus. The Sponsor and the Underwriters may also realize profits or
sustain losses with respect to Securities deposited in each Trust which were
acquired by the Sponsor from underwriting syndicates of which they were
members. The Sponsor has participated as sole underwriter or as manager or as
a member of the underwriting syndicates from which none of the aggregate
principal amount of the Securities in the portfolios of the Fund were
acquired. The Underwriters may further realize additional profit or loss
during the initial offering period as a result of the possible fluctuations in
the market value of the Securities in each Trust after the Date of Deposit,
since all proceeds received from purchasers of Units (excluding dealer
concessions or agency commissions allowed, if any) will be retained by the
Underwriters. Affiliates of an Underwriter are entitled to the same dealer
concessions or agency commissions that are available to the Underwriter.

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

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

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

FEDERAL TAX STATUS

In the opinion of Chapman and Cutler, counsel for the Sponsor, under existing
law as of the date of this Part II of the 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 when distributed to Unitholders;
however such interest may be taken into account in computing the alternative
minimum tax, an additional tax on branches of foreign corporations and the
environmental tax (the "Superfund Tax" ), as noted below;

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

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

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

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

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

In the case of certain corporations, the alternative minimum tax and the
Superfund Tax for taxable years beginning after December 31, 1986 depends upon
the corporation's alternative minimum taxable income, which is the
corporation's taxable income with certain adjustments. One of the adjustment
items used in computing the alternative minimum taxable income and the
Superfund Tax of a corporation (other than an S Corporation, Regulated
Investment Company, Real Estate Investment Trust, or REMIC) is an amount equal
to 75% of the excess of such corporation's "adjusted current earnings" 
over an amount equal to its alternative minimum taxable income (before such
adjustment item and the alternative tax net operating loss deduction). "
Adjusted current earnings" includes all tax exempt interest, including
interest on all of the Bonds in the Fund. Under current Code provisions, the
Superfund Tax does not apply to tax years beginning on or after January 1,
1996. However, the Superfund Tax could be extended retroactively. Under the
provisions of Section 884 of the Code, a branch profits tax is levied on the
"effectively connected earnings and profits" of certain foreign
corporations which include tax-exempt interest such as interest on the Bonds
in the Trust. Unitholders should consult their tax advisers with respect to
the particular tax consequences to them including the corporate alternative
minimum tax, the Superfund Tax and the branch profits tax imposed by Section
884 of the Code.

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

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

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

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

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

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

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

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

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

Ownership of the Units may result in collateral federal income tax
consequences to certain taxpayers, including, without limitation, corporations
subject to either the environmental tax or the branch profits tax, financial
institutions, certain insurance companies, certain S corporations, individual
recipients of Social Security or Railroad Retirement benefits and taxpayers
who may be deemed to have incurred (or continued) indebtedness to purchase or
carry tax-exempt obligations. Prospective investors should consult their tax
advisors as to the applicability of any collateral consequences. On December
7, 1995, the U.S. Treasury Department released proposed legislation that, if
adopted, could affect the United States federal income taxation of non-United
States Unitholders and the portion of the Trust's income allocable to
non-United States Unitholders. Similar language, which would be effective on
the date of enactment, was included in the Health Insurance Reform Bill as
passed by the U.S. Senate on April 23, 1996.

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

DESCRIPTION OF RATINGS

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

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

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

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

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

II. Nature of and provisions of the obligation.

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

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

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

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

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

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

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

Moody's Investors Service, Inc. A brief description of the applicable Moody's
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.

As published by the rating companies.

                 For Unit Investment Trusts Sponsored by
             Van Kampen American Capital Distributors, Inc.

Van Kampen American Capital Distributors, Inc.
One Parkview Plaza
Oakbrook Terrace, Illinois 60181

Gentlemen:

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

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

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

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

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

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

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

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

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

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

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

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

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

    14.   Miscellaneous.  We confirm that we are a member in good
standing of the National Association of Securities Dealers, Inc.
     
     We confirm that we will take reasonable steps to provide the
Preliminary Prospectus or final Prospectus to any person making written
request therefor to us and to make the Preliminary Prospectus or the
final Prospectus available to each person associated with us expected to
solicit  customers' orders for the Units prior to  the  effective
registration date and the final Prospectus if he is expected to offer the
Units after the effective date.  We understand that you will supply us
upon our request with sufficient copies of such prospectuses to comply
with the foregoing.
     
     This Agreement is being executed by us and delivered to you in
duplicate.  Upon your confirmation hereof and of agreements in identical
form with each of the other Underwriters, this Agreement shall constitute
a valid and binding contract between us.
                                    
                                    Very truly yours,
                                    
                                    
                                    
                                    

Confirmed as of the date set forth     Indicated below our firm name and 
at the head of this Agreement          address exactly as we wish to appear

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   278
(hereinafter  referred  to  as  the  "Fund"),  in  connection  with   the
preparation, execution and delivery of a Trust Agreement dated August 15,
1996   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.  333-09189)  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 278
             ______________________________________________

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 278 (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 August 15,
1996  (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.
     
     Based  upon the foregoing and upon an investigation of such  matters
of law as we consider to be applicable, we are of the opinion that, under
existing Federal income tax law:
     
          (i)   Each Trust is not an association taxable as a corporation
     but will be governed by the provisions of subchapter J (relating  to
     trusts) of chapter 1, Internal Revenue Code of 1986 (the "Code").
     
         (ii)    Each Unitholder will be considered as owning a pro  rata
     share  of each asset of the respective Trust in the proportion  that
     the  number  of Units of such Trust held by him bears to  the  total
     number  of  Units  outstanding  of such  Trust.   Under  subpart  E,
     subchapter J of chapter 1 of the Code, income of each Trust will  be
     treated as income of each Unitholder of the respective Trust in  the
     proportion described, and an item of Trust income will have the same
     character in the hands of a Unitholder as it would have in the hands
     of  the  Trustee.  Accordingly, to the extent that the income  of  a
     Trust  consists  of interest 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  (and  no
     other)  interest received with respect to his Units attributable  to
     such industrial development bonds or such private activity bonds  is
     includable   in   his  gross  income.   In  the  case   of   certain
     corporations,  interest on the Bonds is included  in  computing  the
     alternative minimum tax pursuant to Section 56(c) of the  Code,  the
     environmental  tax (the "Superfund Tax") imposed by Section  59A  of
     the  Code, and the branch profits tax imposed by Section 884 of  the
     Code with respect to U.S. branches of foreign corporations.
     
        (iii)    Gain  or  loss will be recognized to a  Unitholder  upon
     redemption  or sale of his Units.  Such gain or loss is measured  by
     comparing the proceeds of such redemption or sale with the  adjusted
     basis   of  the  Units  represented  by  his  Certificate.    Before
     adjustment, such basis would normally be cost if the Unitholder  had
     acquired  his Units by purchase, plus his aliquot share of  advances
     by the Trustee to the Trust to pay interest on Bonds delivered after
     the  Unitholder's settlement date to the extent that  such  interest
     accrued  on  the  Bonds  during  the period  from  the  Unitholder's
     settlement  date  to  the  date such  Bonds  are  delivered  to  the
     respective Trust, but only to the extent that such advances  are  to
     be repaid to the Trustee out of interest received by such Trust with
     respect to such Bonds.  In addition, such basis will be increased by
     the  Unitholder's  aliquot  share  of  the  accrued  original  issue
     discount  (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 an 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 interest received by the Trust,  if
     any,  on  Bonds delivered after the Unitholder's settlement date  to
     the extent that such interest accrued on the Bonds during the period
     from  the  Unitholder's settlement date to the date such  Bonds  are
     delivered  to  the Trust, must be reduced by the annual amortization
     of  bond  premium, if any, on Bonds held by the Trust  and  must  be
     increased  by  the Unitholder's share of the accrued original  issue
     discount  (and market discount, if the Unitholder elects to  include
     market  discount in income as it accures) 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  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 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.  Insurance  has  been
     obtained for such bonds, or, in the case of a commitment, the  bonds
     will  be  ultimately insured under the terms of  such  an  insurance
     policy,  which  are  designated  as  issuer  insured  bonds  on  the
     portfolio pages of the respective Trusts in the prospectus  for  the
     Fund, by the issuer of such bonds.  Insurance obtained by the issuer
     is  effective so long as such bonds remain outstanding.  For each of
     these  bonds,  we  have  been advised that the  aggregate  principal
     amount of such bonds listed on the portfolio page for the respective
     Trust  was  acquired by the applicable Trust and  are  part  of  the
     series of such bonds listed on the portfolio page for the respective
     Trust in the aggregate principal amount listed on the portfolio page
     for  the respective Trust.  Based upon the assumption that the bonds
     acquired  by the applicable Trust are part of the series covered  by
     an  insurance  policy  or,  in the case of  a  commitment,  will  be
     ultimately  insured under the terms of such an insurance policy,  it
     is  our  opinion  that any amounts received by the applicable  Trust
     representing maturing interest on such bonds will be excludable from
     federal  gross  income if, and to the same extent as, such  interest
     would have been so excludable if paid in normal course by the Issuer
     provided that, at the time such policies are purchased, the  amounts
     paid for such policies are reasonable, customary and consistent with
     the reasonable expectation that the issuer of the bonds, rather than
     the insurer, will pay debt service on the bonds.  Paragraph (ii)  of
     this opinion is accordingly applicable to such payment.
     
     Sections  1288 and 1272 of the Code provide a complex set  of  rules
governing  the  accrual of original issue discount.  These rules  provide
that  original issue discount accrues either on the basis of  a  constant
compound interest rate or ratably over the term of the Bond, depending on
the  date the Bond was issued.  In addition, special rules apply  if  the
purchase price of a Bond exceeds the original issue price plus the amount
of original issue discount which 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 57(a)(5) of the Code issued on  or  after
August  15,  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 and  the  Superfund
Tax  depend  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 and the Superfund Tax of a corporation (other than
an  S  corporation, Regulated Investment Company, Real Estate  Investment
Trust  or  REMIC) for taxable years beginning after 1989,  is  an  amount
equal  to  75%  of  the  excess of such corporation's  "adjusted  current
earnings"  over an amount equal to its AMTI (before such adjustment  item
and the alternative tax net operating loss deduction).  "Adjusted current
earnings"  includes all tax-exempt interest, including  interest  on  all
Bonds  in  the  Trust,  and tax-exempt original  issue  discount.   Under
current  Code provisions, the Superfund Tax does not apply to  tax  years
beginning on or after January 1, 1996.  However, the Superfund Tax  could
be extended retroactively.
     
     Effective  for  tax  returns  filed after  December  31,  1987,  all
taxpayers  are required to disclose to the Internal Revenue  Service  the
amount of tax-exempt interest earned during the year.
     
     Section  265  of the Code provides for a reduction in  each  taxable
year  of 100 percent of the otherwise deductible interest on indebtedness
incurred or continued by financial institutions, to which either  Section
585  or Section 593 of the Code applies, to purchase or carry obligations
acquired  after  August 7, 1986, the interest on  which  is  exempt  from
Federal  income taxes for such taxable year.  Under rules  prescribed  by
Section  265,  the  amount  of  interest  otherwise  deductible  by  such
financial  institutions  in  any taxable  year  which  is  deemed  to  be
attributable  to  tax-exempt obligations acquired after August  7,  1986,
will  be  the amount that bears the same ratio to the interest  deduction
otherwise  allowable (determined without regard to Section  265)  to  the
taxpayer  for  the taxable year as the taxpayer's average adjusted  basis
(within  the meaning of Section 1016) of tax-exempt obligations  acquired
after August 7, 1986, bears to such average adjusted basis for all assets
of   the  taxpayer,  unless  such  financial  institution  can  otherwise
establish,  under regulations, to be prescribed by the Secretary  of  the
Treasury, the amount of interest on indebtedness incurred or continued to
purchase  or  carry  such  obligations.  On December  7,  1995  the  U.S.
Treasury Department released proposed legislation that, if adopted, would
generally  extend  the financial institution rules to  all  corporations,
effective for obligations acquired after the date of announcement.
     
     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 the income tax law of the  Commonwealth  of
Virginia  ("Virginia"), which is based upon the Federal Law, to determine
its  applicability  to the Virginia Quality Trust (the "Virginia  Trust")
being  created  as part of the Fund and to the holders of  Units  in  the
Virginia  Trust  who  are  residents  of  the  Commonwealth  of  Virginia
("Virginia Unitholders").
     
     The  assets  of  the Virginia Trust will consist of interest-bearing
obligations issued by or on behalf of Virginia ("Virginia") or  counties,
municipalities,  authorities  or  political  subdivisions  thereof   (the
"Bonds").  Although we express no opinion with respect to the issuance of
the  Bonds,  in rendering our opinion expressed herein, we  have  assumed
that:  (i)  the Bonds were validly issued, (ii) the interest  thereon  is
excludable  from gross income for federal income tax purposes  and  (iii)
the  interest thereon is exempt from income tax imposed by Virginia  that
is  applicable  to  individuals and corporations  (the  "Virginia  Income
Tax").  This opinion does not address the taxation of persons other  than
full  time  residents of Virginia.  Based upon the foregoing  it  is  our
opinion  that  under  Virginia income tax law, as presently  enacted  and
construed:
     
          (a)    The  Virginia Trust is not an association taxable  as  a
     corporation for Virginia income tax purposes and each Unitholder  of
     the  Virginia  Trust  will be treated as the owner  of  a  pro  rata
     portion  of the assets held by the Virginia Trust and the income  of
     such  portion  of  the  assets held by the Virginia  Trust  will  be
     treated  as  income of the Unitholder for purposes of  the  Virginia
     Income Tax.
     
          (b)    Income on the Bonds which is exempt from Virginia Income
     Tax  when received by the Virginia Trust, and which would be  exempt
     from  Virginia Income Tax if received directly by a Unitholder, will
     retain  its  status  as exempt from such tax when  received  by  the
     Virginia Trust and distributed to such Unitholder.
     
          (c)    Each Unitholder will recognize gain or loss for purposes
     of  the  Virginia  Income  Tax if the Trustee  disposes  of  a  bond
     (whether  by  redemption, sale or otherwise) or  if  the  Unitholder
     redeems or sells Units of the Virginia Trust to the extent that such
     a  transaction  results  in  a  recognized  gain  or  loss  to  such
     Unitholder  for federal income tax purposes, except as described  in
     this  paragraph.  Virginia law provides that all income from certain
     tax-exempt obligations issued under the laws of Virginia,  including
     any  profits made from the sale of such Bonds, shall be exempt  from
     all  taxation  by  Virginia.  Although we express  no  opinion,  the
     Virginia  Department  of  Taxation  has  indicated  that  the  gains
     recognized  for  federal  income tax  purposes  on  such  tax-exempt
     obligations  would  not  be  subject to  Virginia  Income  Taxation.
     Accordingly, any such gain relating to the disposition of  any  Bond
     that  would  not be subject to Virginia Income Tax if the  Bond  was
     held directly by a Unitholder will retain its tax-exempt status  for
     purposes of the Virginia Income Tax when the Bond is disposed of  by
     the Virginia Trust or when the Unitholder is deemed to have disposed
     of  his  pro rata portion of such Bond upon the disposition  of  his
     Unit  provided  that  such  gain can be determined  with  reasonable
     certainty and subtantiated.
     
          (d)    The  Virginia Income Tax does not permit a deduction  of
     interest  paid on indebtedness incurred or continued to purchase  or
     carry Units in the Virginia Trust to the extent that interest income
     related  to  the  Ownership of Units is exempt from Virginia  Income
     Tax.
     
     In  the  case of Unitholders subject to the Virginia Bank  Franchise
Tax, the income derived by such a Unitholder from his pro rata portion of
the Bonds held by the Virginia Trust may affect the determination of such
Unitholder's  Bank Franchise Tax.  Prospective investors  should  consult
their tax advisors.
     
     We  have  not examined any of the Bonds to be deposited and held  in
the  Virginia  Trust or the proceedings for the issuance thereof  or  the
opinions of the bond counsel with respect thereto, and therefore  express
no  opinion  as to the exemption from Virginia Income Tax of interest  on
the Virginia Bonds if received directly by a Unitholder.  In addition, we
express  no  opinion with respect to any taxes or items other than  those
described above.

                                    Very truly yours,

Insured Municipals Income Trust and
Investors' Quality Tax-Exempt Trust,
Multi-Series 278
c/o The Bank of New York,
As Trustee
101 Barclay Street, 17 West
New York, New York 10286

Dear Sirs:
     
     We  have acted as special counsel for the Insured Municipals  Income
Trust  and  Investors'  Quality Tax-Exempt Trust, Multi-Series  278  (the
"Fund") consisting of California Insured Municipals Income Trust,  Series
156,  Michigan Insured Municipals Income Trust, Series 139  and  Virginia
Investors' Quality Tax-Exempt Trust, Series 73 and (in the aggregate  the
"Trusts"  and  individually "Trusts") for the purpose of determining  the
applicability   of  certain  New  York  taxes  under  the   circumstances
hereinafter described.
     
        The   Fund  is  created  pursuant  to  a  Trust  Agreement   (the
"Indenture"), dated as of today (the "Date of Deposit") among Van  Kampen
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 333-09189)
under  the  Securities  Act of 1933, as amended (the  "Prospectus"),  the
objectives  of the Fund are the generation of income exempt from  Federal
taxation and as regards each Trust denominated with the name of  a  state
exempt  from income tax, if any, of the denominated in the name  of  that
Trust to the extent indicated in the Prospectus.  No opinion is expressed
herein with regard to the Federal or State tax aspects of the bonds,  the
Fund,  and  units of the Trust (the "Units"), or any interest,  gains  or
losses in respect thereof.
     
     As  more fully set forth in the Indenture and in the Prospectus, the
activities of the Trustee will include the following:
     
     On  the Date of Deposit, the Depositor will deposit with the Trustee
with  respect  to  each Trusts, the total principal  amount  of  interest
bearing  obligations and/or contracts for the purchase  thereof  together
with  an  irrevocable  letter of credit in the amount  required  for  the
purchase  price and accrued interest, if any, and, in the case of  Trusts
denominated as "Insured," an insurance policy purchased by the  Depositor
evidencing the insurance guaranteeing the timely payment of principal and
interest  of  the obligations comprising the corpus of that  Trust  other
than  those  obligations the timely payment of principal and interest  of
which  are  guaranteed  by an insurance policy purchased  by  the  issuer
thereof  or a prior owner, which may include the Depositor prior  to  the
Date  of  Deposit, as more fully set forth in the Prospectus with respect
to each Trust.
     
     We  understand  with  respect to the obligations  described  in  the
preceding  paragraph  that  all  insurance,  whether  purchased  by   the
Depositor,  the issuer or a prior owner, provides, or will provide,  that
the  amount paid by the insurer in respect of any bond may not exceed the
amount of principal and interest due on the bond and such payment will in
no  event  relieve the issuer from its continuing obligation to pay  such
defaulted  principal and interest in accordance with  the  terms  of  the
obligation.
     
     The Trustee will not participate in the selection of the obligations
to  be deposited in the Fund, and, upon the receipt thereof, will deliver
to  the  Depositor  a  registered certificate for  the  number  of  Units
representing the entire capital of each of the Trusts as more  fully  set
forth in the Prospectus and the Registration Statement.  The Units, which
are  represented by certificates ("Certificates"), will be offered to the
public  by  the  Prospectus upon the effectiveness  of  the  Registration
Statement.
     
     The  duties  of the Trustee, which are ministerial in  nature,  will
consist  primarily  of crediting the appropriate accounts  with  interest
received by each of the Trusts and with the proceeds from the disposition
of  obligations held in each of the Trusts and the distribution  of  such
interest  and  proceeds to the Unit holders of that Trust.   The  Trustee
will  also  maintain  records of the registered holders  of  Certificates
representing  an interest in each Trust and administer the redemption  of
Units  by such Certificate holders and may perform certain administrative
functions with respect to an automatic investment option.
     
     Generally, obligations held in the Fund may be removed therefrom  by
the  Trustee only upon redemption prior to their stated maturity, at  the
direction of the Depositor in the event of an advance refunding, or  upon
the  occurrence of certain other specified events which adversely  affect
the sound investment character of the Fund, such as default by the issuer
in  payment  of interest or principal on the obligation and no  provision
for  payment is made therefor either pursuant to the portfolio  insurance
or  otherwise  and  the Depositor fails to instruct the  Trustee,  within
thirty (30) days after notification, to hold such obligation.
     
     Prior  to  the termination of the Fund, the Trustee is empowered  to
sell  Bonds, from a list furnished by the Evaluator, only for the purpose
of  redeeming Units tendered to it and of paying expenses for which funds
are  not  available.  The Trustee does not have the  power  to  vary  the
investment of any Unit holder in the Fund, and under no circumstances may
the  proceeds  of  sale of any obligations held by the Fund  be  used  to
purchase new obligations to be held therein.
     
     Article  9-A  of  the New York Tax Law imposes a  franchise  tax  on
business corporations, and, for purposes of that Article, Section  208(l)
defines  the  term  "corporation" to include, among  other  things,  "any
business conducted by a trustee or trustees wherein interest or ownership
is evidenced by certificate or other written instrument."
     
     The Regulations promulgated under Section 208 provide as follows:
          
          The term "trust" includes any business conducted by a
          trustee or trustees in which interest or ownership is
          evidenced by certificate or other written instrument.
          Such  a  trust  includes, but is not limited  to,  an
          association  commonly  referred  to  as  a  "business
          trust"  or  "Massachusetts  trust."   In  determining
          whether  a  trustee  or  trustees  are  conducting  a
          business,   the   form  of  the   agreement   is   of
          significance  but  is  not controlling.   The  actual
          activities  of  the  trustee or trustees,  not  their
          purposes  and  powers, will be regarded  as  decisive
          factors in determining whether a trust is subject  to
          tax  under Article 9-A.  The mere investment of funds
          and   the   collection  of  income  therefrom,   with
          incidental replacement of securities and reinvestment
          of  funds,  does  not constitute  the  conduct  of  a
          business in the case of a business conducted  by  the
          trustee  or trustees. 20 NYCRR 1-2.3(b)(2) (July  11,
          1990).
     
     New York cases dealing with the question of whether a trust will  be
subject  to the franchise tax have also delineated the general rule  that
where  a  trustee  merely invests funds and collects and distributes  the
income therefrom, the trust is not engaged in business and is not subject
to  the  franchise tax.  Burrell v. Lynch, 274 A.D. 347, 84 N.Y.S.2d  171
(3rd Dept. 1948), order resettled, 274 A.D. 1073, 85 N.Y.S.2d 705 (1949).
     
     An opinion of the Attorney General of the State of New York, 47 N.Y.
Atty.  Gen. Rep. 213 (Nov. 24, 1942), it was held that where the  trustee
of  an  unincorporated investment trust was without authority to reinvest
amounts  received  upon  the sales of securities  and  could  dispose  of
securities  making  up  the  trust only upon  the  happening  of  certain
specified  events or the existence of certain specified  conditions,  the
trust was not subject to the franchise tax.
     
     In  the  instant  situation, the Trustee is not  empowered  to  sell
obligations contained in the corpus of the Fund and reinvest the proceeds
therefrom.   Further, the power to sell such obligations  is  limited  to
circumstances  in  which  the  creditworthiness  or  soundness   of   the
obligation  is  in question or in which cash is needed to  pay  redeeming
Unit holders or to pay expenses, or where the Fund is liquidated pursuant
to  the termination of the Indenture.  Only in circumstances in which the
issuer of an obligation attempts to refinance it can the Trustee exchange
an  obligation for a new security.  In substance, the Trustee will merely
collect  and  distribute  income and will  not  reinvest  any  income  or
proceeds, and the Trustee has no power to vary the investment of any Unit
holder in a Trust.
     
     Under Subpart E of Part I, Subchapter J of Chapter 1 of the Internal
Revenue  Code of 1986, as amended (the "Code"), the grantor  of  a  trust
will  be deemed to be the owner of the trust under certain circumstances,
and  therefore  taxable  on  his proportionate  interest  in  the  income
thereof.   Where this Federal tax rule applies, the income attributed  to
the  grantor will also be income to him for New York income tax purposes.
See  TSB-M-78(9)(c), New York Department of Taxation and Finance June 23,
1978.
     
     By  letter, dated today, Messrs. Chapman and Cutler, counsel for the
Depositor,  rendered their opinion that each Unit holder of a Trust  will
be  considered  as  owning a share of each asset of  that  Trust  in  the
proportion  that  the number of Units held by such holder  bears  to  the
total  number  of  Units outstanding and the income of a  Trust  will  be
treated  as  the  income  of  each Unit holder  of  that  Trust  in  said
proportion pursuant to Subpart E of Part E, subchapter J of Chapter 1  of
the Code.
     
     Based  on  the foregoing and on the opinion of Messrs.  Chapman  and
Cutler,   counsel  for  the  Depositor,  dated  today,  upon   which   we
specifically  rely,  we  are  of the opinion that  under  existing  laws,
rulings  and court decisions interpreting the laws of the State and  City
of New York.

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

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

     3.   Unit holders who are not residents of the State of New York are
not  subject to the income tax laws 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 that opinion no New York  State  stock
transfer  tax  will  be  payable  in  respect  of  any  transfer  of  the
Certificates  by  reason of the exemption contained in paragraph  (a)  of
Subdivision 8 of Section 270 of the New York Tax Law.
     
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement relating to the Units and to the use of  our  name
and  the reference to our firm in the Registration Statement and  in  the
Prospectus.

     Re: California Insured Municipals Income Trust, Series 156
                                    
Dear Sirs:
     
     We  have acted as special California counsel for Van Kampen American
Capital  Distributors,  Inc.,  as Sponsor  and  Depositor  of  California
Insured  Municipals Income Trust, Series 156, (the "Fund"), in connection
with  the  issuance under the Trust Indenture and Agreement dated  August
15,  1996,  among  Van  Kampen American Capital  Distributors,  Inc.,  as
Sponsor and Depositor, American Portfolio Evaluation Services, a division
of  Van  Kampen American Capital Investment Advisory Corp., as Evaluator,
and  The  Bank  of  New York through its Wall Street Trust  division,  as
Trustee,  of 3,087  Units  of fractional undivided interest in  the  Fund
(the "Units") in exchange for certain bonds, as well as "regular-way" and
"when-issued"  contracts  for  the purchase  of  bonds  (such  bonds  and
contracts are hereinafter referred to collectively as the "Securities").
     
     In  connection  therewith, we have examined such corporate  records,
certificates  and other documents and such questions of law  as  we  have
deemed necessary or appropriate for the purpose of this opinion, and,  on
the  basis  of  such  examination, and upon existing  provisions  of  the
Revenue  and  Taxation Code of the State of California,  we  are  of  the
opinion that:
     
           1.    The  Fund is not an association taxable as a corporation
     and  the  income of the Fund will be treated as the  income  of  the
     certificateholders under the income tax laws of California.
     
           2.    Amounts treated as interest on the underlying securities
     which  are exempt from tax under California personal income tax  and
     property  tax laws when received by the Fund will, under such  laws,
     retain  their  status  as tax-exempt interest  when  distributed  to
     certificateholders.  However, interest on the underlying  securities
     attributed to a certificateholder which is a corporation subject  to
     the  California franchise tax laws may be includable  in  its  gross
     income for purposes of determining its California franchise tax.
     
          3.   Under California income tax law, each certificateholder in
     the  Fund  will  have a taxable event when the Fund  disposes  of  a
     security  (whether  by  sale, exchange, redemption,  or  payment  at
     maturity)  or  when the certificateholder redeems  or  sells  Units.
     Because of the requirement that tax cost basis be reduced to reflect
     amortization   of   bond   premium,  under  some   circumstances   a
     certificateholder may realize taxable gain when Units  are  sold  or
     redeemed for an amount equal to, or less than, their original  cost.
     The  total tax cost of each Unit to a certificateholder is allocated
     among  each of the bond issues held in the Fund (in accordance  with
     the proportion of the Fund comprised by each bond issue) in order to
     determine  his per unit tax cost for each bond issue;  and  the  tax
     cost reduction requirements relating to amortization of bond premium
     will  apply  separately to the per unit cost  of  each  bond  issue.
     Certificateholders' bases in their Units, and the  bases  for  their
     fractional interest in each Fund asset, may have to be adjusted  for
     their  pro  rata  share  of accrued interest received,  if  any,  on
     securities   delivered  after  the  certificateholders'   respective
     settlement dates.
     
           4.    Under  the California personal property tax laws,  bonds
     (including  the Securities) or any interest therein is  exempt  from
     such tax.
     
          5.   Any proceeds paid under the insurance policy issued to the
     Trustee  of the fund with respect to the Securities which  represent
     maturing interest on defaulted obligations held by the Trustee  will
     be  exempt from California personal income tax if, and to  the  same
     extent  as, such interest would have been so exempt if paid  by  the
     issuer of the defaulted obligations.
     
           6.    Under Section 17280(b)(2) of the California Revenue  and
     Taxation  Code,  interest on indebtedness incurred or  continued  to
     purchase  or  carry  Units of the Trust is not  deductible  for  the
     purposes  of  the  California  personal  income  tax.   While  there
     presently  is  no California authority interpreting this  provision,
     Section  17280(b)(2) directs the California Franchise Tax  Board  to
     prescribe   regulations  determining  the  proper   allocation   and
     apportionment of interest costs for this purpose.  The Franchise Tax
     Board  has  not  yet  proposed or prescribed such  regulations.   In
     interpreting  the generally similar Federal provision, the  Internal
     Revenue  Service has taken the position that such indebtedness  need
     not  be  directly  traceable to the purchase or  carrying  of  Units
     (although  the  Service  has  not contended  that  a  deduction  for
     interest  on indebtedness incurred to purchase or improve a personal
     residence  or to purchase goods or services for personal consumption
     will  be disallowed).  In the absence of conflicting regulations  or
     other  California  authority,  the California  Franchise  Tax  Board
     generally  has  interpreted California statutory tax  provisions  in
     accord  with  Internal  Revenue Service interpretations  of  similar
     Federal provisions.
     
     Opinions relating to the validity of securities and the exemption of
interest thereon from State of California income tax are rendered by bond
counsel to the issuing authority at the time securities are issued and we
have  relied  solely  upon such opinions, or, as to  securities  not  yet
delivered,  forms  of  such  opinions contained  in  official  statements
relating  to  such securities.  Except in certain instances in  which  we
acted as bond counsel to issuers of securities, and as such made a review
of proceedings relating to the issuance of certain securities at the time
of their issuance, we have not made any review of proceedings relating to
the issuance of securities or the bases of bond counsels' opinions.
     
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (SEC No. 333-09189) 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.

                                    Very truly yours,

                   Tax-Exempt Trust, Multi-Series 278
         (Michigan Insured Municipals Income Trust, Series 139)

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  278 (Michigan  Insured  Municipals  Income
Trust,  Series 139 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. SS206.1  et
seq.; M.S.A. SS7.557 (101) et seq.) (the "Michigan Income Tax"), the City
Income Tax Act (M.C.L.A. SS141.501 et seq.; M.S.A. SS5.3194 (1) et seq.),
which  incorporates  the "Uniform City Income Tax Ordinance,"  the  First
Class  School District excise tax upon income (M.C.L.A. SS380.451; M.S.A.
SS15.4451)  (collectively, the "income tax laws"),  the  Michigan  Single
Business  Tax Act (M.C.L.A. 208.1 et seq.; M.S.A. SS7.558(1)  et  seq.)
(the  "Single  Business  Tax")  and the  Michigan  Tax  on  ownership  of
Intangible   Personal  Property  (M.C.L.A.  SS205.131  et  seq.;   M.S.A.
SS7.556(1) et seq.) (the "Intangibles Tax").  You have also requested our
opinion  regarding the tax status of proceeds payable from  an  insurance
policy  to  be obtained by either the Fund or by the issuer of the  Bonds
involved,  guaranteeing prompt payment of principal and interest  on  all
Bonds in the portfolio of the Fund.
     
     The Michigan Trust, its formation, its proposed method of operation,
the  rights of owners of Certificates representing Units, the  nature  of
such ownership and the portfolio of investments of the Michigan Trust are
described  and set forth in the Prospectus dated August 19,  1996,  filed
with  the  Securities  and Exchange commission in Registration  No.  333-
09189.   In  giving our opinion set forth hereunder, we have relied  upon
the  facts contained in such Registration Statement, including  the  fact
that,  at  the  respective  dates  of issuance  of  the  underlying  Debt
obligations,  opinions  of  bond  counsel  to  the  respective   Michigan
authorities issuing such Debt Obligations were given with respect to  the
validity  of the Debt Obligations and the exemption of the same,  and  of
the interest thereon, from Michigan taxation.
     
     Based on the above, it is our opinion that:
     
     The Michigan Trust and the owners of Units will, in our opinion,  be
treated  for  purposes of the Michigan income tax  laws  and  the  Single
Business Tax in substantially the same manner as they are for purposes of
the  Federal income tax laws, as currently enacted.  Accordingly, we have
relied  upon  the  opinion  of Messrs.  Chapman  and  Cutler  as  to  the
applicability  of Federal income tax under the Internal Revenue  Code  of
1986,  as  currently amended, to the Michigan Trust and  the  Holders  of
Units.
     
     Under  the  income tax laws of the State of Michigan,  the  Michigan
Trust  is not an association taxable as a corporation; the income of  the
Michigan  Trust will be treated as the income of the Holders of Units  of
the  Michigan  Trust  and be deemed to have been received  by  them  when
received by the Michigan Trust.  Interest on the Debt Obligations in  the
Michigan  Trust  which is exempt from tax under the Michigan  income  tax
laws  when received by the Michigan Trust will retain its status  as  tax
exempt interest to the Holders of Units of the Michigan Trust.
     
     For  purposes of the Michigan income tax laws, each Holder of  Units
of  the  Michigan Trust will be considered to have received his pro  rata
share  of interest on each Debt Obligation in the Michigan Trust when  it
is  received by the Michigan Trust, and each Holder will have  a  taxable
event  when the Michigan Trust disposes of a Debt Obligation (whether  by
sale,  exchange,  redemption or payment at maturity)  or  when  the  Unit
Holder  redeems  or  sells  his  Unit,  to  the  extent  the  transaction
constitutes  a  taxable event for Federal income tax purposes.   The  tax
cost of each Unit to a Unit Holder will be established and allocated  for
purposes of the Michigan income tax laws in the same manner as such  cost
is established and allocated for Federal income tax purposes.
     
     Under  the  Michigan  Intangibles Tax, the  Michigan  Trust  is  not
taxable and the pro rata ownership of the underlying Debt obligations, as
well  as the interest thereon, will be exempt to the Holders of Units  to
the  extent  the Michigan Trust consists of obligations of the  State  of
Michigan  or  its  political  subdivisions  or  municipalities,   or   of
obligations of possessions of the United States.
     
     The  Michigan Single Business Tax replaced the tax on corporate  and
financial  institution  income under the Michigan  Income  Tax,  and  the
intangible  tax with respect to those intangibles of persons  subject  to
the  Single  Business Tax the income from which would  be  considered  in
computing  the  Single Business Tax.  Persons are subject to  the  Single
Business Tax only if they are  engaged in "business activity," as defined
in the Act.  Under the Single Business Tax, both interest received by the
Michigan  Trust  on  the  underlying  Debt  Obligations  and  any  amount
distributed from the Michigan Trust to a Unit Holder, if not included  in
determining taxable income for Federal income tax purposes, is  also  not
included in the adjusted tax base upon which the Single Business  Tax  is
computed,  of  either  the Michigan Trust or the Unit  Holders.   If  the
Michigan  Trust  or  the Unit Holders have a taxable  event  for  Federal
income tax purposes when the Michigan Trust disposes of a Debt Obligation
(whether  by  sale, exchange, redemption or payment at maturity)  or  the
Holder  redeems or sells his Unit, an amount equal to any  gain  realized
from  such taxable event which was included in the computation of taxable
income  for  Federal  income tax purposes (plus an amount  equal  to  any
capital gain of an individual realized in connection with such event  but
excluded in computing that individual's Federal taxable income)  will  be
included  in  the tax base against which, after allocation, apportionment
and other adjustments, the Single Business Tax is computed.  The tax base
will be reduced by an amount equal to any capital loss realized from such
a  taxable  event,  whether  or  not the capital  loss  was  deducted  in
computing Federal taxable income in the year the loss occurred.   Holders
should consult their tax advisor as to their status under Michigan law.
     
     Any proceeds paid under an insurance policy issued to the Trustee of
the Fund, or paid under individual policies obtained by issuers of Bonds,
which, when received by the Unit Holders, represent maturing interest  on
defaulted  obligations held by the Trustee, will be excludable  from  the
Michigan income tax laws and the Single Business Tax if, and to the  same
extent  as,  such interest would have been so excludable if paid  by  the
issuer  of the defaulted obligations.  While treatment under the Michigan
Intangibles  Tax  is  not  premised upon  the  characterization  of  such
proceeds  under  the  Internal Revenue Code, the Michigan  Department  of
Treasury should adopt the same approach as under the Michigan income  tax
laws and the Single Business tax.
     
     Chapman  and  Cutler  of 111 West Monroe Street,  Chicago,  Illinois
60603,  are entitled to rely on this opinion as though it were  addressed
to them.
     
     We  also  advise you that, as the Tax Reform Act of 1986  eliminates
the  capital  gain deduction for tax years beginning after  December  31,
1986,  the  federal adjusted gross income, the computation base  for  the
Michigan  Income Tax, of a Unit Holder will be increased  accordingly  to
the  extent  such  capital  gains are realized when  the  Michigan  Trust
disposes of a Debt Obligation or when the Unit Holder redeems or sells  a
Unit,  to  the  extent such transaction constitutes a taxable  event  for
Federal income tax purposes.
     
     We  hereby consent to the reference to Miller, Canfield, Paddock and
Stone  under the heading "Michigan Tax Status" in the Prospectus relating

Re:Insured Municipals Income Trust and Investors' Quality Tax-Exempt
   Trust, Multi-Series 278, consisting of:  California Insured Municipals
   Income Trust, Series 156 and Michigan Insured Municipals Income Trust,
   Series 139.
     
     Pursuant to your request for a Standard & Poor's rating on the units
of  the  above-captioned  trust,  SEC #333-09189  we  have  reviewed  the
information presented to us and have assigned a 'AAA' rating to the units
of  the trust and a 'AAA' rating to the securities contained in the trust
for  as  long  as  they  remain in the trust.   The  ratings  are  direct
reflections, of the portfolio of the trust, which will be composed solely
of  securities  covered by bond insurance policies  that  insure  against
default  in  the payment of principal and interest on the  securities  so
long  as they remain in the trust.  Since such policies have been  issued
by  one  or  more  insurance companies which have been assigned  a  'AAA'
claims  paying ability rating by S&P, S&P has assigned a 'AAA' rating  to
the  units of the trust and to the securities contained in the trust  for
as long as they remain in the trust.
     
     You have permission to use the name of Standard & Poor's Corporation
and  the above-assigned ratings in connection with your dissemination  of
information relating to these units, provided that it is understood  that
the ratings are not "market" ratings nor recommendations to buy, hold, or
sell  the  units of the trust or the securities contained in  the  trust.
Further,  it should be understood the rating on the units does  not  take
into  account the extent to which fund expenses or portfolio asset  sales
for  less than the fund's purchase price will reduce payment to the  unit
holders  of  the  interest  and principal required  to  be  paid  on  the
portfolio  assets.   S&P reserves the right to advise  its  own  clients,
subscribers,  and the public of the ratings.  S&P relies on  the  sponsor
and  its  counsel,  accountants, and other experts for the  accuracy  and
completeness of the information submitted in connection with the ratings.
S&P  does  not  independently verify the truth or accuracy  of  any  such
information.
     
     This letter evidences our consent to the use of the name of Standard
&  Poor's Corporation in connection with the rating assigned to the units
in  the registration statement or prospectus relating to the units or the
trust.  However, this letter should not be construed as a consent by  us,
within the meaning of Section 7 of the Securities Act of 1933, to the use
of  the  name  of  Standard & Poor's Corporation in connection  with  the
ratings  assigned  to the securities contained in  the  trust.   You  are
hereby  authorized to file a copy of this letter with the Securities  and
Exchange Commission.
     
     Please  be  certain to send us three copies of your final prospectus
as  soon  as it becomes available.  Should we not receive them  within  a
reasonable  time  after the closing or should they  not  conform  to  the
representations made to us, we reserve the right to withdraw the rating.
     
     We  are pleased to have had the opportunity to be of service to you.
If we can be of further help, please do not hesitate to call upon us.
                                    
                                    Sincerely,
