Information contained herein is subject to completion or amendment. A
registration statement relating to these securities has been filed with the
Securities and Exchange Commission. These securities may not be sold nor may
offers to buy be accepted prior to the time the registration statement becomes
effective. This Prospectus shall not constitute an offer to sell or the
solicitation of an offer to buy nor shall there be any sale of these
securities in any State in which such offer, solicitation or sale would be
unlawful prior to registration or qualification under the securities laws of
any State. 
   
                Preliminary Prospectus Dated September 6, 1995
                            Subject To Completion 

September 6, 1995

                        Van Kampen American Capital

Van Kampen American Capital Insured Income Trust, Series 50

The Trust. The Trust initially consists of delivery statements relating to
contracts to purchase debt obligations and, thereafter, will consist of a
$9,425,000 aggregate principal amount portfolio principally comprised of
long-term corporate, taxable municipal or government debt obligations. The
Trust is comprised of 9,555 Units. 
    
Attention Foreign Investors. If you are not a United States citizen or
resident, your interest income from the Trust may not be subject to Federal
withholding taxes if certain conditions are met. See "Tax Status". 

Investment Objective of the Trust. The investment objective of the Trust is a
high level of current income consistent with preservation of capital through a
diversified investment in a fixed portfolio principally consisting of
long-term corporate and taxable municipal debt securities issued after July
18, 1984 (the "Obligations"). See "Investment Objectives and
Portfolio Selection". There is no assurance that the Trust will achieve
its objective. The payment of interest and the preservation of principal is,
of course, dependent upon the continuing ability of the issuers and/or
obligors of the Obligations and of the insurer thereof to meet their
respective obligations. Units of the Trust are not insured by the FDIC, are
not deposits or other obligations of, or guaranteed by, any depository
institution or any government agency and are subject to investment risk,
including possible loss of the principal amount invested.
   
The Trust and "AAA" Rating. Insurance guaranteeing the payments of
principal and interest, when due, on the Obligations in the portfolio of the
Trust has been obtained from an insurance company either by the Trust or by
the issuer of the Obligations involved, by a prior owner of the Obligations or
by the Sponsor prior to the deposit of such Obligations in the Trust. See "
Insurance on the Obligations" on page 12. Insurance obtained by the Trust
applies only while the Obligations involved are retained in such Trust while
insurance obtained on Preinsured Obligations is effective so long as such
Obligations are outstanding. The Trustee, upon the sale of an Obligation
insured under an insurance policy obtained by the Trust, has a right to obtain
from the insurer involved permanent insurance for such Obligation upon the
payment of a single predetermined insurance premium and any expenses related
thereto from the proceeds of the sale of such Obligation. It should be noted
that the insurance, in either case, relates only to the Obligations in the
Trust and not to the Units offered hereby or to the market value thereof. As a
result of such insurance, the Units of the 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 the Trust or sales by the Trust
of Obligations for less than the purchase price paid by the Trust will reduce
payment to Unitholders of the interest and principal required to be paid on
such Obligations. See "Insurance on the Obligations". No
representation is made as to any insurer's ability to meet its commitments. 
    
Public Offering Price. The Public Offering Price of the Units of the Trust
during the initial offering period is equal to the aggregate offering price of
the Obligations in the portfolio and cash, if any, in the Principal Account
held or owned by the Trust divided by the number of Units outstanding, plus
the applicable sales charge plus accrued interest, if any. For sales charges
in the secondary market, see "Public Offering--General". If the
Obligations in the Trust were available for direct purchase by investors, the
purchase price of the Obligations 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 100 or
more Units. If Units were available for purchase at 8:00 A.M. Central Time on
the Date of Deposit, the Public Offering Price per Unit would have been that
amount set forth in the "Summary of Essential Financial Information" 
for the Trust. See "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 Estimated Current
Return and Estimated Long-Term Return to Unitholders were as set forth under
"Summary of Essential Financial Information". The methods of
calculating Estimated Current Return and Estimated Long-Term Return are set
forth in the footnotes to the "Summary of Essential Financial
Information" and under "Estimated Current Return and Estimated
Long-Term Return". 
   
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 "Rights of
Unitholders--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. The first monthly distribution will be $3.77 per Unit and will be made
on October 15, 1995 to Unitholders of record on October 1, 1995. Record dates
for monthly distributions will be the first day of each month and record dates
for semi-annual distributions will be the first day of the months indicated
under "Per Unit Information". Distributions will be made on the
fifteenth day of the month subsequent to the respective record dates. The
first distribution of funds from the Principal Account, if any, will be made
on December 15, 1995 to Unitholders of record on December 1, 1995, and
thereafter such distributions will be made on a semi-annual basis, except
under certain special circumstances (see "Rights of
Unitholders--Distributions of Interest and Principal"). 
    
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 price of the Obligations in the portfolio of the Trust
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 Obligations 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 Obligations plus interest
accrued to the date of settlement (see "Rights of Unitholders--Redemption
of Units"). Neither the bid nor offering prices of the underlying
Obligations or of the Units, absent situations in which Obligations 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 the
Trust. See "Public Offering--Public Market". 

Reinvestment Option. Unitholders have the opportunity to have their
distributions reinvested into an open-end, management investment company as
described herein. Foreign investors should note, however, that any interest
distributions resulting from such a reinvestment program will be subject to
U.S. Federal income taxes, including withholding taxes. See "Rights of
Unitholders--Reinvestment Option". 

Risk Factors. An investment in Units of the Trust 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 general economic conditions. See "Risk Factors".

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

<F2>Many unit investment trusts issue a number of units such that each unit
represents approximately $1,000 principal amount of underlying securities. In
determining the number of Units for this Trust, however, the Sponsor has
elected not to follow this format but rather to provide that number of Units
which will establish as close as possible as of the Date of Deposit a Public
Offering Price per Unit of $1,000.

<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--Public Market." 

<F4>Excluding insurance costs. The Estimated Annual Expenses are expected to
fluctuate periodically (see "Trust Operating Expenses--Miscellaneous
Expenses").

<F5>The Estimated Current Returns and Estimated Long-Term Returns are increased
for transactions entitled to a reduced sales charge (see "Public
Offering--General").

<F6>The Estimated Current Returns are calculated by dividing the Estimated Net
Annualized 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 Obligations while the
Public Offering Price will vary with changes in the offering price of the
underlying Obligations; therefore, there is no assurance that the present
Estimated Current Returns indicated above will be realized in the future. The
Estimated Long-Term Returns are 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 Obligations in each 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 Obligations and the expenses of the Trust will
change, there is no assurance that the present Estimated Long-Term Return as
indicated above will be realized in future. The Estimated Current Returns and
Estimated Long-Term Returns are expected to differ because the calculation of
the Estimated Long-Term Return reflects the estimated date and amount of
principal returned while the Estimated Current Return calculation includes
only net annual interest income and Public Offering Price. Neither rate
reflects the true return to Unitholders which may be lower because of a
possible delay in the first payment to Unitholders. 

<F7>These figures are based on 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 Obligations. The estimated cash flows for the Trust are set
forth under "Estimated Cash Flows to Unitholders".

THE TRUST 
   
Van Kampen American Capital Insured Income Trust, Series 50 (the "Trust") 
was created under the laws of the State of New York pursuant to a
Trust Agreement (the "Trust Agreement"), dated the Date of Deposit,
with 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 Trust may be an appropriate medium for investors who desire to participate
in a portfolio of long-term taxable fixed income securities issued after July
18, 1984 with greater diversification than they might be able to acquire
individually. Diversification of the Trust's assets will not eliminate the
risk of loss always inherent in the ownership of securities. For a breakdown
of the portfolio see "Trust Portfolio" . In addition, securities of the
type initially deposited in the portfolio of the Trust are often not available
in small amounts and may, in the case of any privately placed securities, be
available only to institutional investors. 
   
On the Date of Deposit, the Sponsor deposited with the Trustee the Obligations
indicated under "Portfolio" herein, including delivery statements
relating to contracts for the purchase of certain such obligations and
irrevocable letters of credit issued by a financial institution in the
aggregate amount required for such purchases (the "Obligations" ).
Thereafter, the Trustee, in exchange for the Obligations so deposited,
delivered to the Sponsor the certificates evidencing the ownership of 9,555
Units of the Trust. Unless otherwise terminated as provided therein, the Trust
Agreement will terminate at the end of the calendar year prior to the fiftieth
anniversary of its execution. All of the Obligations in the Trust are
long-term debt instruments with maturities ranging from 2018 to 2026. The
dollar weighted average life of the Obligations in the Trust is 28 years. 

Each Unit initially offered represents a 1/9,555 undivided interest in the
Trust. To the extent that any Units are redeemed by the Trustee, the
fractional undivided interest in the Trust represented by each unredeemed Unit
will increase, although the actual interest in the 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. 
    

INVESTMENT OBJECTIVES AND PORTFOLIO SELECTION 

The investment objective of the Trust is to provide a high level of current
income consistent with safety of principal by investing in a professionally
selected portfolio consisting of long-term corporate, taxable municipal debt
or government obligations issued after July 18, 1984. 

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

Neither the Public Offering Price nor any evaluation of Units for purposes of
repurchases or redemptions reflects any element of value for the insurance
obtained by the Trust unless Obligations are in default in payment of
principal or interest or in significant risk of such default. See "Public
Offering--Offering Price". 

In order for Obligations to be eligible for insurance, they must have credit
characteristics which would qualify them for at least the Standard & Poor's
rating of "BBB-" or at least the Moody's Investors Service, Inc.
rating of "Baa", which in brief represent the lowest ratings for
securities of investment grade (see "Description of Obligation Ratings"). 
Insurance is not a substitute for the basic credit of an issuer, but
supplements the existing credit and provides additional security therefor. If
an issue is accepted for insurance, a non-cancellable policy for the prompt
payment of interest and principal on the Obligations, when due, is issued by
the insurer. A monthly premium is paid by the Trust for the insurance obtained
by it. The Trustee has the right to obtain permanent insurance from a
Portfolio Insurer in connection with the sale of an Obligation insured under
the insurance policy obtained from the respective Portfolio Insurer by a Trust
upon the payment of a single predetermined insurance premium from the proceeds
of the sale of such Obligation. Accordingly, any Obligation in a Trust is
eligible to be sold on an insured basis. All Obligations insured by a
Portfolio Insurer or by a Preinsured Obligation Insurer receive a "AAA" 
 rating by Standard & Poor's. Standard & Poor's describes securities it rates
"AAA" as having "the highest rating assigned by Standard & Poor's
to a debt obligation. Capacity to pay interest and repay principal is
extremely strong." See "Insurance on the Obligations". 

In selecting Obligations for the Trust, the following facts, among others,
were considered by the Sponsor: (a) the prices of the Obligations relative to
other obligations of comparable quality and maturity, (b) the diversification
of Obligations as to purpose of issue and location of issuer, (c) the
availability and cost of insurance for the prompt payment of principal and
interest on the Obligations and (d) whether the debt obligations were issued
after July 18, 1984. 

TRUST PORTFOLIO 
   
Portfolio. Series 50 consists of 12 issues, 10 of which have been issued by
public utilities, one of which has been issued by a municipality and one of
which is a U.S. Treasury bond. 
    
Replacement Obligations. Because certain of the Obligations in the Trust 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 the 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 Obligation. In the
event of a failure to deliver any Obligation that has been purchased for the
Trust under a contract, including those securities purchased on a "when,
as and if issued" basis ("Failed Obligations"), the Sponsor is
authorized under the Trust Agreement to direct the Trustee to acquire other
securities ("Replacement Obligations") to make up the original corpus
of the affected Trust. 

The Replacement Obligations 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 Obligations. The Replacement Obligations shall (i) be long-term
corporate or taxable municipal bonds, debentures, notes or other straight debt
obligations (whether secured or unsecured and whether senior or subordinated)
without equity or other conversion features, with fixed maturity dates
substantially the same as those of the Failed Obligations having no warrants
or subscription privileges attached; (ii) be payable in United States
currency; (iii) not be when, as and if issued obligations or restricted
securities; (iv) be issued after July 18, 1984 if interest thereon is United
States source income; (v) be issued or guaranteed by an issuer subject to or
exempt from the reporting requirements under Section 13 or 15(d) of the
Securities Exchange Act of 1934 (or similar provisions of law) or in effect
guaranteed, directly or indirectly, by means of a lease agreement, agreement
to buy securities, services or products, or other similar commitment of the
credit of such an issuer to the payment of the substitute Obligations; (vi)
not cause the Units of the Trust to cease to be rated AAA by Standard &
Poor's; and (vii) be eligible for (and when acquired be insured under) the
insurance obtained by the Trust. Whenever a Replacement Obligation has been
acquired for the Trust, the Trustee shall, within five days thereafter, notify
all Unitholders of such Trust of the acquisition of the Replacement Obligation
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 Obligation exceeded the cost of the
Replacement Obligation 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 variations to improve a Unitholder's investment. 

If the right of limited substitution described in the preceding paragraph
shall not be utilized to acquire Replacement Obligations in the event of a
failed contract, the Sponsor will refund the sales charge attributable to such
Failed Obligations to all Unitholders of the affected Trust and distribute the
principal and accrued interest (at the coupon rate of such Failed Obligations
to the date the Failed Obligations are removed from the Trust) attributable to
such Failed Obligations 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. In the event a Replacement Obligation should not be
acquired by a Trust, the Estimated Net Annual Interest Income per Unit for the
Trust would be reduced and the Estimated Current Return and the 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. 

Redemption of Obligations. Certain of the Obligations in the Trust are 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 Obligations 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 and it may also offset the current return on
Units of the Trust involved. The portfolio contains a listing of the sinking
fund and call provisions, if any, with respect to each of the Obligations.
Extraordinary optional redemptions and mandatory redemptions result from the
happening of certain events. Generally, events that may permit the
extraordinary optional redemption of Obligations or may require the mandatory
redemption of Obligations include, among others: the substantial damage or
destruction by fire or other casualty of the project for which the proceeds of
the Obligations 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 Obligations 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 Obligations were used uneconomical;
changes in law or an administrative or judicial decree which renders the
performance of the agreement under which the proceeds of the Obligations 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 Obligations are issued on the issuer of the Obligations or the
user of the proceeds of the Obligations; 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 Obligations; an overestimate of the
costs of the project to be financed with the proceeds of the Obligations
resulting in excess proceeds of the Obligations which may be applied to redeem
Obligations; or an underestimate of a source of funds securing the Obligations
resulting in excess funds which may be applied to redeem Obligations. The
Sponsor is unable to predict all of the circumstances which may result in such
redemption of an issue of Obligations. See "Portfolio" for the Trust
and footnote (3) in "Notes to Portfolio" . 

RISK FACTORS
   
Public Utility Issues. Approximately 84% of the aggregate principal amount of
the Obligations in the Trust are obligations of public utility issuers. In
view of this an investment in the Trust should be made with an understanding
of the characteristics of such issuers and the risks which such an investment
may entail. General problems of such issuers would include the difficulty in
financing large construction programs in an inflationary period, the
limitations on operations and increased costs and delays attributable to
environmental considerations, the difficulty of the capital market in
absorbing utility debt, the difficulty in obtaining fuel at reasonable prices
and the effect of energy conservation. All of such issuers have been
experiencing certain of these problems in varying degrees. In addition,
Federal, state and municipal governmental authorities may from time to time
review existing, and impose additional, regulations governing the licensing,
construction and operation of nuclear power plants, which may adversely affect
the ability of the issuers of certain of the Obligations in the portfolio to
make payments of principal and/or interest on such Obligations. 
    
Utilities are generally subject to extensive regulation by state utility
commissions which, for example, establish the rates which may be charged and
the appropriate rate of return on an approved asset base, which must be
approved by the state commissions. Certain utilities have had difficulty from
time to time in persuading regulators, who are subject to political pressures,
to grant rate increases necessary to maintain an adequate return on investment
and voters in many states have the ability to impose limits on rate
adjustments (for example, by initiative or referendum). Any unexpected
limitations could negatively affect the profitability of utilities whose
budgets are planned far in advance. Also, changes in certain accounting
standards currently under consideration by the Financial Accounting Standards
Board could cause significant write-downs of assets and reductions in earnings
for many investor-owned utilities. In addition, gas pipeline and distribution
companies have had difficulties in adjusting to short and surplus energy
supplies, enforcing or being required to comply with long-term contracts and
avoiding litigation from their customers, on the one hand, or suppliers, on
the other. 

Certain of the issuers of the Obligations in the Trust may own or operate
nuclear generating facilities. Governmental authorities may from time to time
review existing, and impose additional, requirements governing the licensing,
construction and operation of nuclear power plants. Nuclear generating
projects in the electric utility industry have experienced substantial cost
increases, construction delays and licensing difficulties. These have been
caused by various factors, including inflation, high financing costs, required
design changes and rework, allegedly faulty construction, objections by groups
and governmental officials, limits on the ability to finance, reduced
forecasts of energy requirements and economic conditions. This experience
indicates that the risk of significant cost increases, delays and licensing
difficulties remains present through to completion and achievement of
commercial operation of any nuclear project. Also, nuclear generating units in
service have experienced unplanned outages or extensions of scheduled outages
due to equipment problems or new regulatory requirements sometimes followed by
a significant delay in obtaining regulatory approval to return to service. A
major accident at a nuclear plant anywhere, such as the accident at a plant in
Chernobyl, could cause the imposition of limits or prohibitions on the
operation, construction or licensing of nuclear units in the United States. 

Other general problems of the gas, water, telephone and electric utility
industry (including state and local joint action power agencies) include
difficulty in obtaining timely and adequate rate increases, difficulty in
financing large construction programs to provide new or replacement facilities
during an inflationary period, rising costs of rail transportation to
transport fossil fuels, the uncertainty of transmission service costs for both
interstate and intrastate transactions, changes in tax laws which adversely
affect a utility's ability to operate profitably, increased competition in
service costs, recent reductions in estimates of future demand for electricity
and gas in certain areas of the country, restrictions on operations and
increased cost and delays attributable to environmental considerations,
uncertain availability and increased cost of capital, unavailability of fuel
for electric generation at reasonable prices, including the steady rise in
fuel costs and the costs associated with conversion to alternate fuel sources
such as coal, availability and cost of natural gas for resale, technical and
cost factors and other problems associated with construction, licensing,
regulation and operation of nuclear facilities for electric generation,
including among other considerations the problems associated with the use of
radioactive materials and the disposal of radioactive wastes, and the effects
of energy conservation. Each of the problems referred to could adversely
affect the ability of the issuers of any utility bonds in the Trust to make
payments due on these bonds. 

In view of the pending investigations and the other uncertainties discussed
above, there can be no assurance that any company's share of the full cost of
nuclear units under construction ultimately will be recovered in rates or of
the extent to which a company could earn an adequate return on its investment
in such units. The likelihood of a significantly adverse event occurring in
any of the areas of concern described above varies, as does the potential
severity of any adverse impact. It should be recognized, however, that one or
more of such adverse events could occur and individually or collectively could
have a material adverse impact on the financial condition or the results of
operations of a company's ability to make interest and principal payments on
its outstanding debt. 
   
Taxable Municipal Issues. Approximately 11% of the aggregate principal amount
of the Obligations in the Trust are taxable obligations of municipal issuers.
In view of this an investment in the Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. Obligations of municipal issuers can be either
general obligations of a government entity that are backed by the taxing power
of such entity or 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. However,
the taxing power of any governmental entity may be limited by provisions of
state constitutions or laws and an entity's credit will depend on many
factors, including an erosion of the tax base due to population declines,
natural disasters, declines in the state's industrial base or inability to
attract new industries, economic limits on the ability to tax without eroding
the tax base and the extent to which the entity relies on Federal or state
aid, access to capital markets or other factors beyond the entity's control. 

As a result of the current recession's adverse impact upon both their revenues
and expenditures, as well as other factors, many state and local governments
are confronting deficits and potential deficits which are the most severe in
recent years. Many issuers are facing highly difficult choices about
significant tax increases or spending reductions in order to restore budgetary
balance. Failure to implement these actions on a timely basis could force the
issuers to depend upon market access to finance deficits or cash flow needs. 

In addition, certain of the Obligations in the Trust may be obligations of
issuers who rely in whole or in part on ad valorem real property taxes as a
source of revenue. Recently, certain proposals, in the form of state
legislative proposals or voter initiatives, to limit ad valorem real property
taxes have been introduced in various states. 

Revenue bonds, on the other hand, are payable only from revenues derived from
a particular facility or class of facilities, or, in some cases, from the
proceeds of a special excise tax or other special revenue source. The ability
of an issuer of revenue bonds to make payments of principal and/or interest on
such bonds is primarily dependent upon the success or failure of the facility
or class of facilities involved or whether the revenues received from an
excise tax or other special revenue source are sufficient to meet obligations. 

Typically, interest income received from municipal issues is exempt from
Federal income taxation under Section 103 of the Internal Revenue Code of
1986, as amended (the "Code") and therefore is not includible in the
gross income of the owners thereof. However, interest income received for
taxable municipal obligations is not exempt from Federal income taxation under
Section 103 of the Code. Thus, owners of taxable municipal obligations
generally must include interest on such obligations in gross income for
Federal income tax purposes and treat such interest as ordinary income. 

Certain of the Obligations in the Trust may be obligations which are payable
from and secured by revenues derived from the ownership and operation of
facilities such as airports, bridges, turnpikes, port authorities, convention
centers and arenas. In view of this an investment in such a Trust should be
made with an understanding of the characteristics of such issuers and the
risks which such an investment may entail. The major portion of an airport's
gross operating income is generally derived from fees received from signatory
airlines pursuant to use agreements which consist of annual payments for
leases, occupancy of certain terminal space and service fees. Airport
operating income may therefore be affected by the ability of the airlines to
meet their obligations under the use agreements. The air transport industry is
experiencing significant variations in earnings and traffic, due to increased
competition, excess capacity, increased costs, deregulation, traffic
constraints and other factors, and several airlines are experiencing severe
financial difficulties. The Sponsor cannot predict what effect these industry
conditions may have on airport revenues which are dependent for payment on the
financial condition of the airlines and their usage of the particular airport
facility. Similarly, payment on Bonds related to other facilities is dependent
on revenues from the projects, such as user fees from ports, tolls on
turnpikes and bridges and rents from buildings. Therefore, payment may be
adversely affected by reduction in revenues due to such factors as increased
cost of maintenance, decreased use of a facility, lower cost of alternative
modes of transportation, scarcity of fuel and reduction or loss of rents. 

Certain of the Obligations in the Trust may be health care revenue bonds. In
view of this an investment in such a Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. Ratings of bonds issued for health care facilities
are often based on feasibility studies that contain projections of occupancy
levels, revenues and expenses. A facility's gross receipts and net income
available for debt service may be affected by future events and conditions
including, among other things, demand for services and the ability of the
facility to provide the services required, physicians' confidence in the
facility, management capabilities, competition with other health care
facilities, efforts by insurers and governmental agencies to limit rates,
legislation establishing state rate-setting agencies, expenses, the cost and
possible unavailability of malpractice insurance, the funding of Medicare,
Medicaid and other similar third party payor programs, government regulation
and the termination or restriction of governmental financial assistance,
including that associated with Medicare, Medicaid and other similar third
party payor programs. Pursuant to recent Federal legislation, Medicare
reimbursements are currently calculated on a prospective basis utilizing a
single nationwide schedule of rates. Prior to such legislation Medicare
reimbursements were based on the actual costs incurred by the health facility.
The current legislation may adversely affect reimbursements to hospitals and
other facilities for services provided under the Medicare program. Such
adverse changes also may adversely affect the ratings of Securities held in
the portfolios of the Trust; however, because of the insurance obtained by the
Trust, the "AAA" rating of the Units of each of the Trust would not be
affected. 
   
Zero Coupon Bonds. Approximately 5% of the Obligations in the Trust are 
"zero coupon" U.S. Treasury bonds. See footnote (6) in "Notes to
Portfolio". 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 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.
    

ESTIMATED CURRENT RETURN AND ESTIMATED LONG-TERM RETURN 

As of the opening of business on the Date of Deposit, the Estimated Current
Returns and the Estimated Long-Term Returns were those indicated in the 
"Summary of Essential Financial Information" for the Trust. The Estimated
Current Returns are 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 Obligations while the Public Offering Price will
vary with changes in the offering price of the underlying Obligations;
therefore, there is no assurance that the present Estimated Current Return
will be realized in the future. Estimated Long-Term Returns are 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 the Obligations 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 Obligations and the
expenses of a Trust will change, there is no assurance that the present
Estimated Long-Term Returns will be realized in the future. Estimated Current
Returns and Estimated Long-Term Returns are expected to differ because the
calculation of Estimated Long-Term Returns reflects the estimated date and
amount of principal returned while Estimated Current Returns calculations
include only Net Annual Interest Income and Public Offering Price. Neither
rate reflects the true return to Unitholders which is lower because neither
includes the effect of the delay in the first payment to Unitholders. 

In order to acquire certain of the Obligations contracted for by the Sponsor
for deposit in the Trust, it may be necessary for the Sponsor or Trustee to
pay on the settlement dates for delivery of such Obligations amounts covering
accrued interest on such Obligations which exceed (1) the amounts paid by
Unitholders and (2) the amounts which will be made available through cash
furnished by the Sponsor on the Date of Deposit, which amount of cash may
exceed the interest which would accrue to the First Settlement Date. The
Trustee has agreed to pay for any amounts necessary to cover any such excess
and will be reimbursed therefor, without interest, when funds become available
from interest payments on the particular Obligations with respect to which
such payments may have been made. 

TRUST OPERATING EXPENSES 

Initial Costs. All costs and expenses incurred in creating and establishing
the Trust, 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
fees for evaluations and other out-of-pocket expenses have been borne by the
Sponsor at no cost to the Trust. 

Compensation of Sponsor and Evaluator. The Sponsor will not receive any fees
in connection with its activities relating to the Trust. However, American
Portfolio Evaluation Services, a division of Van Kampen American Capital
Investment Advisory Corp., which is a wholly-owned subsidiary of the Sponsor
(the "Evaluator"), will receive an annual supervisory fee, which is
not to exceed the amount set forth under "Summary of Essential Financial
Information", for providing portfolio supervisory services for the Trust.
Such fee (which is based on the number of Units outstanding on January 1 of
each year) may exceed the actual costs of providing such supervisory services
for the Trust, but at no time will the total amount received for portfolio
supervisory services rendered to Series 1 and subsequent series of Van Kampen
Merritt Insured Income Trust or its successor trusts (Van Kampen American
Capital Insured Income Trust) 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" (which is based on the
outstanding principal amount of obligations on January 1 of each year) for
regularly evaluating the Trust's portfolio. Both of the foregoing fees may be
increased without approval of the Unitholders by amounts not exceeding
proportionate increases under the category "All Services Less Rent of
Shelter" in the Consumer Price Index published by the United States
Department of Labor or, if such category is no longer published, in a
comparable category. The Sponsor and the Underwriters will receive sales
commissions and may realize other profits (or losses) in connection with the
sale of Units and the deposit of the Obligations as described under 
"Public Offering-- Sponsor and Underwriter Compensation". 
   
Trustee's Fee. For its services, the Trustee will receive a fee based on the
aggregate outstanding principal amount of Obligations in the Trust as of the
opening of business on January 2 and July 2 of each year as set forth under
"Summary of Essential Financial Information." Such fee will be
computed at $.51 and $.91 per $1,000 principal amount, respectively, for those
portions of the Trust representing semi-annual and monthly distribution plans.
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 fee for ordinary recurring services would initially amount to
$4,807. Assuming in the alternative that all Unitholders had elected the
monthly distribution plan, such fee would initially amount to $8,577. The
Trustee's fees are payable monthly on or before the fifteenth day of each
month from the Interest Account to the extent funds are available and then
from the Principal Account. 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. 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 the Trust is expected to result
from the use of these funds. For a discussion of the services rendered by the
Trustee pursuant to its obligations under the Trust Agreement, see "Rights
of Unitholders--Reports Provided" and "Trust Administration". 

Insurance Premiums. The cost of the portfolio insurance obtained by the Trust
is $11,615 per annum so long as the Trust retains the Obligations. Premiums,
which are Trust expenses, are payable monthly by the Trustee on behalf of the
Trust. As Obligations in the portfolio are redeemed by their respective
issuers or are sold by the Trustee, the amount of the premium will be reduced
in respect of those Obligations no longer owned by and held in such Trust. If
the Trustee exercises the right to obtain Permanent Insurance, the premium
payable for such Permanent Insurance will be paid solely from the proceeds of
the sale of the related Obligations. The premiums for such Permanent Insurance
with respect to each Obligation will decline over the life of the Obligation. 
    
Miscellaneous Expenses. The following additional charges are or may be
incurred by the Trust: (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 Trust 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 Trust
without negligence, bad faith or willful misconduct on its part, (f) any
special custodial fees payable in connection with the sale of any bonds in a
Trust, (g) expenditures incurred in contacting Unitholders upon termination of
the Trust and (h) costs incurred to reimburse the Trustee for advancing funds
to the Trust 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 Trust. 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 Trust, the Trustee has the power to sell
Obligations to pay such amounts. 

INSURANCE ON THE OBLIGATIONS 

Insurance has been obtained by the Trust guaranteeing prompt payment of
interest and principal, when due (as more fully described below), in respect
of all the Obligations in the Trust (except for issues for which insurance has
been obtained by the issuer of the Obligations). See "Investment
Objectives and Portfolio Selection" . Each insurance policy obtained by the
Trust is non-cancellable and will continue in force so long as such Trust is
in existence, the Portfolio Insurer involved is still in business and the
Obligations described in such policy continue to be held by such Trust (see
"Portfolio"). Non-payment of premiums on a policy obtained by the
Trust will not result in the cancellation of insurance but will force the
Portfolio Insurer involved to take action against the Trustee to recover
premium payments due it. The Trustee in turn will be entitled to recover such
payments from the Trust. Premium rates for each issue of Obligations protected
by the policy obtained by the Trust are fixed for the life of the Trust. The
premium for any insurance policy or policies obtained by an issuer of
Obligations has been paid in advance by such issuer and any such policy or
policies are non-cancellable and will continue in force so long as the
Obligations so insured are outstanding and the Portfolio Insurer involved
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 Trust insurance guarantees the timely payment of principal
and interest on the Obligations as they fall due. For the purposes of the
Portfolio Insurance, "when due" generally means the stated maturity
date for the payment of principal and interest. However, in the event (a) an
issuer of an Obligation defaults in the payment of principal or interest on
such Obligation, (b) such issuer enters into a bankruptcy proceeding or (c)
the maturity of such Obligation is accelerated, the Portfolio Insurer involved
has the option, in its sole discretion, for a limited period of time after
receiving notice of the earliest to occur of such a default, bankruptcy
proceeding or acceleration to pay the outstanding principal amount of such
Obligation plus accrued interest to the date of such payment and thereby
retire the Obligation from a Trust prior to such Obligation's stated maturity
date. The insurance does not guarantee the market value of the Obligations or
the value of the Units. Insurance obtained by a Trust is only effective as to
Obligations owned by and held in such Trust. In the event of a sale of any
such Obligation by the Trustee, such insurance terminates as to such
Obligation on the date of sale. 

Pursuant to an irrevocable commitment of the Portfolio Insurers, the Trustee,
upon the sale of an Obligation covered under a portfolio insurance policy
obtained by the Trust, has the right to obtain permanent insurance with
respect to such Obligation (i.e., insurance to maturity of the Obligations
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
Obligation. Accordingly, any Obligation in the 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 Trust would receive
net proceeds (sale of Obligation proceeds less the insurance premium and
related expenses attributable to the Permanent Insurance) from such sale in
excess of the sale proceeds if such Obligations were sold on an uninsured
basis.The insurance premium with respect to each Obligation eligible for
Permanent Insurance would be determined based upon the insurability of each
Obligation as of the Date of Deposit and would not be increased or decreased
for any change in the creditworthiness of each Obligation. 

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

Except as indicated below, insurance obtained by the 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 Obligations 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 equal to the difference between
(i) the market value of an Obligation 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 Obligations not covered by
Permanent Insurance. See "Public Offering--Offering Price" herein for
a more complete description of the Trust's method of valuing defaulted
Obligations which have a significant risk of default. 

The portfolio insurance policies obtained by the Trust were issued by either
AMBAC Indemnity or CapMAC. The other policy (or commitment therefor) obtained
by an Obligation issuer was issued by AMBAC Indemnity. See "Investment
Objectives and Portfolio Selection". 

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

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

CapMAC is wholly owned by CapMAC Holdings Inc. ("Holdings"), a company
that is owned by a group of institutional and other investors, including
CapMAC's management and employees. Neither Holdings nor any of its
stockholders is obligated to pay any claims under any policy issued by CapMAC
or any debts of CapMAC or to make additional capital contributions. 

CapMAC is regulated by the Superintendent of Insurance of the State of New
York. In addition, CapMAC is subject to regulation by the insurance
departments of the other jurisdictions in which it is licensed. Such insurance
laws regulate, among other things, the amount of net exposure per risk that
CapMAC may retain, capital transfers, dividends, investment of assets, changes
in control, transactions with affiliates and consolidations and acquisitions.
CapMAC is subject to periodic regulatory examinations by the same regulatory
authorities. 

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

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

As at December 31, 1994 and 1993, CapMAC had qualified statutory capital
(which consists of policyholders' surplus and contingency reserve) of
approximately $170 million and $168 million, respectively, and had not
incurred any debt obligations. Article 69 of the New York State Insurance Law
requires CapMAC to establish and maintain the contingency reserve, which is
available to cover claims under policies issued by CapMAC. 

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

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

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

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

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

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

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

Financial Security is approximately 91.6% owned by US WEST, Inc. and 8.4%
owned by The Tokio Marine and Fire Insurance Co., Ltd. ("Tokio Marine"). 
Neither US WEST, Inc. nor Tokio Marine is obligated to pay the debts of or

of Financial Security and its consolidated subsidiaries were, in accordance
with generally accepted accounting principles, approximately $479,110,000
(unaudited) and $220,078,000 (unaudited), and the total shareholders' equity
and the total unearned premium reserve, respectively, of Financial Security

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

Financial Security's claims-paying ability is rated "Aaa" by Moody's
Investors Service, Inc., and "AAA" by Standard & Poor's, Nippon
Investors Service Inc., Duff & Phelps Inc. and Australian Ratings Pty. Ltd.

"Triple-A" by both Moody's and Standard & Poor's. 

As of December 31, 1994, Capital Guaranty had more than $15.7 billion in net
exposure outstanding (excluding defeased issues). The total statutory
policyholders' surplus and contingency reserve of Capital Guaranty was
$196,529,000, and the total admitted assets were $303,723,316 as reported to
the Insurance Department of the State of Maryland as of December 31, 1994.
Financial statements for Capital Guaranty Insurance Company, that have been
prepared in accordance with statutory insurance accounting standards, are
available upon request. The address of Capital Guaranty's headquarters and its
telephone number are Steuart Tower, 22nd Floor, One Market Plaza, San
Francisco, CA 94105-1413 and (415) 995-8000. 

Because the Obligations are insured by CapMAC, MBIA or AMBAC Indemnity as to
the timely payment of principal and interest, when due (as more fully
described above), and on the basis of the various reinsurance agreements in
effect, Standard & Poor's has assigned to the Units of each Trust its 
"AAA" investment rating. See "Investment Objectives and Portfolio
Selection" . The obtaining of this rating by each 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 the Trusts or of the Units. 
   
On the date of this Prospectus, the Estimated Current Return on the
Obligations in the Trust portfolio was 6.78% based on the monthly plan of
distribution, after payment of the insurance premiums payable by the Trust,
while the Estimated Long-Term Return on the Obligations in the Trust portfolio
was 6.80%. The Estimated Current Return on an identical portfolio without the
insurance obtained by the Trust would have been 6.90% based on the monthly
distibution plan on such date, while the Estimated Long-Term Return on an
identical portfolio without the insurance obtained by the Trust would have
been 6.93%. 
    
An objective of portfolio insurance obtained by the Trust is to obtain a
higher yield on the Trust portfolio than would be available if all the
Obligations 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 (as more fully described above), on the
Obligations. There is, of course, no certainty that this result will be
achieved. 

In the event of nonpayment of interest or principal, when due (as more fully
described above), in respect of an Obligation, the appropriate Insurer shall
make such payment within 30 days after it has been notified that such
nonpayment has occurred. The appropriate Insurer, as regards any payment it
may make, will succeed to the rights of the Trustee in respect thereof. 

The information relating to the Insurers has been furnished by the respective
Insurers. The financial information with respect to the Insurers 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. 

TAX STATUS 

For purposes of the following discussions and opinions, it is assumed that
interest on each of the Obligations (including the taxable municipal bonds, if
any) is included in gross income for Federal income tax purposes. In the
opinion of Chapman and Cutler, special counsel for the Sponsor, under existing
law: 

The Trust is not an association taxable as a corporation for United States
Federal income tax purposes. 

Each Unitholder will be considered the owner of a pro rata portion of each of
the Trust's assets for Federal income tax purposes under Subpart E, Subchapter
J of Chapter 1 of the Internal Revenue Code of 1986 (the "Code"). Each
Unitholder will be considered to have received his pro rata share of income
derived from each such asset when such income is received by the Trust. Each
Unitholder will also be required to include in taxable income for Federal
income tax purposes, original issue discount with respect to his interest in
any Obligations held by the Trust at the same time and in the same manner as
though the Unitholder were the direct owner of such interest. 

Each Unitholder will have a taxable event when an Obligation of the Trust is
disposed of (whether by sale, exchange, redemption, or payment at maturity) or
when the Unitholder redeems or sells his Units. The cost of the Units to a
Unitholder on the date such Units are purchased is allocated among the
Obligations held in the Trust (in accordance with the proportion of the fair
market values of such Obligations) in order to determine his tax basis for his
pro rata portion in each Obligation. Unitholders must reduce the tax basis of
their Units for their share of accrued interest received, if any, on
Obligations delivered after the date the Unitholders pay for their Units 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 Obligations (whether by sale, exchange, payment on majority,
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 his basis for his
fractional interest in the asset disposed of. The basis of each Unit and of
each Obligation which was issued with original issue discount (including the
Treasury Bonds) must be increased by the amount of accrued original issue
discount and the basis of each Unit and of each Obligation which was purchased
by the Trust at a premium must be reduced by the annual amortization of bond
premium which the Unitholder has properly elected to amortize under Section
171 of the Code. The tax cost reduction requirements of the Code relating to
amortization of bond premium may, under some circumstances, result in the
Unitholder realizing a taxable gain when his Units are sold or redeemed for an
amount equal to or less than his original cost. The Treasury Bonds held by the
Trust are treated as bonds that were originally issued at an original issue
discount provided, pursuant to a Treasury Regulation (the "Regulation") 
issued on December 28, 1992, that the amount of original issue discount
determined under Section 1286 of the Code is not less than a "de
minimis" amount as determined thereunder (as discussed below under 
"Original Issue Discount" ). Because the Treasury Bonds represent interests
in "stripped" bonds, a Unitholder's initial cost for his pro rata
portion of each Treasury Bond held by the Trust (determined at the time he
acquires his Units, in the manner described above) shall be treated as its
"purchase price" by the Unitholder. Original issue discount is
effectively treated as interest for Federal income tax purposes, and the
amount of original issue discount in this case is generally the difference
between the bond's purchase price and its stated redemption price at maturity.
A Unitholder will be required to include in gross income for each taxable year
the sum of his daily portions of original issue discount attributable to the
Treasury Bonds held by the Trust as such original issue discount accrues and
will, in general, be subject to Federal income tax with respect to the total
amount of such original issue discount that accrues for such year even though
the income is not distributed to the Unitholders during such year to the
extent it is not less than a "de minimis" amount as determined under
the Regulation. In general, original issue discount accrues daily under a
constant interest rate method which takes into account the semi-annual
compounding of accrued interest. In the case of the Treasury Bonds, this
method will generally result in an increasing amount of income to the
Unitholders each year. Unitholders should consult their tax advisers regarding
the Federal income tax consequences and accretion of original issue discount. 

Limitations on Deductibility of Trust Expenses by Unitholders. Each
Unitholder's pro rata share of each expense paid by the Trust is deductible by
the Unitholder to the same extent as though the expense had been paid directly
by him, subject to the following limitation. It should be noted that as a
result of the Tax Reform Act of 1986, certain miscellaneous itemized
deductions, such as investment expenses, tax return preparation fees and
employee business expenses will be deductible by an individual only to the
extent they exceed 2% of such individual's adjusted gross income. Temporary
regulations have been issued which require Unitholders to treat certain
expenses of the Trust as miscellaneous itemized deductions subject to this
limitation. 

Acquisition Premium. If a Unitholder's tax basis of his pro rata portion in
any Obligations held by the Trust exceeds the amount payable by the issuer of
the Obligation with respect to such pro rata interest upon the maturity of the
Obligation, such excess would be considered "acquisition premium" 
which may be amortized by the Unitholder at the Unitholder's election as
provided in Section 171 of the Code. Unitholders should consult their tax
advisors regarding whether such election should be made and the manner of
amortizing acquisition premium. 

Original Issue Discount. Certain of the Obligations of the Trust may have been
acquired with "original issue discount." In the case of any
Obligations of the Trust acquired with "original issue discount" that
exceeds a "de minimis" amount as specified in the Code or in the case
of the Treasury Bonds as specified in the Regulation, such discount is
includable in taxable income of the Unitholders on an accrual basis computed
daily, without regard to when payments of interest on such Obligations are
received. The Code provides a complex set of rules regarding the accrual of
original issue discount. These rules provide that original issue discount
generally accrues on the basis of a constant compound interest rate over the
term of the Obligations. Unitholders should consult their tax advisers as to
the amount of original issue discount which accrues. 

Special original issue discount rules apply if the purchase price of the
Obligation by the Trust exceeds its original issue price plus the amount of
original issue discount which would have previously accrued based upon its
issue price (its "adjusted issue price"). Similarly these special
rules would apply to a Unitholder if the tax basis of his pro rata portion of
an Obligation issued with original issue discount exceeds his pro rata portion
of its adjusted issue price. Unitholders should also consult their tax
advisers regarding these special rules.

It is possible that a Corporate Bond that has been issued at an original issue
discount may be characterized as a "high-yield discount obligation" 
within the meaning of Section 163(e)(5) of the Code. To the extent that such
an obligation is issued at a yield in excess of six percentage points over the
applicable Federal rate, a portion of the original issue discount on such
obligation will be characterized as a distribution on stock (e.g., dividends)
for purposes of the dividends received deduction which is available to certain
corporations with respect to certain dividends received by such corporation.

Market Discount. If a Unitholder's tax basis in his pro rata portion of
Obligations is less than the allocable portion of such Obligation's stated
redemption price at maturity (or, if issued with original issue discount, the
allocable portion of its "revised issue price"), such difference will
constitute market discount unless the amount of market discount is "de
minimis" as specified in the Code. Market discount accrues daily computed
on a straight line basis, unless the Unitholder elects to calculate accrued
market discount under a constant yield method. The market discount rules do
not apply to Treasury Bonds because they are stripped debt instruments subject
to special original issue discount rules as discussed above. Unitholders
should consult their tax advisors as to the amount of market discount which
accrues. 

Accrued market discount is generally includable in taxable income to the
Unitholders as ordinary income for Federal tax purposes upon the receipt of
serial principal payments on the Obligations, on the sale, maturity or
disposition of such Obligations by the Trust, and on the sale by a Unitholder
of Units, unless a Unitholder elects to include the accrued market discount in
taxable income as such discount accrues. If a Unitholder does not elect to
annually include accrued market discount in taxable income as it accrues,
deductions for any interest expense incurred by the Unitholder which is
incurred to purchase or carry his Units will be reduced by such accrued market
discount. In general, the portion of any interest expense which was not
currently deductible would ultimately be deductible when the accrued market
discount is included in income. Unitholders should consult their tax advisers
regarding whether an election should be made to include market discount in
income as it accrues and as to the amount of interest expense which may not be
currently deductible. 

Computation of the Unitholder's Tax Basis. The tax basis of a Unitholder with
respect to his interest in an Obligation is increased by the amount of
original issue discount (and market discount, if the Unitholder elects to
include market discount, if any, on the Obligations held by the Trust in
income as it accrues) thereon properly included in the Unitholder's gross
income as determined for Federal income tax purposes and reduced by the amount
of any amortized acquisition premium which the Unitholder has properly elected
to amortize under Section 171 of the Code. A Unitholder's tax basis in his
Units will equal his tax basis in his pro rata portion of all of the assets of
the Trust. 

Recognition of Taxable Gain or Loss Upon Disposition of Obligations by the
Trust or Disposition of Units. A Unitholder will recognize taxable capital
gain (or loss) when all or part of his pro rata interest in an Obligation is
disposed of in a taxable transaction for an amount greater (or less) than his
tax basis therefor. Any gain recognized on a sale or exchange and not
constituting a realization of accrued "market discount," and any loss
will, under current law, generally be capital gain or loss except in the case
of a dealer or financial institution. As previously discussed, gain realized
on the disposition of the interest of a Unitholder in any Obligation deemed to
have been acquired with market discount will be treated as ordinary income to
the extent the gain does not exceed the amount of accrued market discount not
previously taken into income. Any capital gain or loss arising from the
disposition of an Obligation by the Trust or the disposition of Units by a
Unitholder will be short-term capital gain or loss unless the Unitholder has
held his Units for more than one year in which case such capital gain or loss
will be long-term. For taxpayers other than corporations, net capital gains
are subject to a maximum marginal stated tax rate of 28 percent. 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. The tax cost reduction requirements of the
Code relating to amortization of bond premium may under some circumstances,
result in the Unitholder realizing taxable gain when his Units are sold or
redeemed for an amount equal to or less than his original cost.

"The Revenue Reconciliation Act of 1993" (the "Tax Act")
raised tax rates on ordinary income while capital gains remain subject to a
28% maximum stated rate for taxpayers other than corporations. Because some or
all capital gains are taxed at a comparatively lower rate under the Tax Act,
the Tax Act includes a provision that characterizes capital gains as ordinary
income in the case of certain financial transactions that are "conversion
transactions" effective for transactions entered into after April 30,
1993. Unitholders and prospective investors should consult with their tax
advisers regarding the potential effect of this provision on their investment
in Units. 

If the Unitholder disposes of a Unit, he is deemed thereby to have disposed of
his entire pro rata interest in all Trust assets including his pro rata
portion of all of the Obligations represented by the Unit. This may result in
a portion of the gain, if any, on such sale being taxable as ordinary income
under the market discount rules (assuming no election was made by the
Unitholder to include market discount in income as it accrues) as previously
discussed. The tax cost reduction requirements of the Code relating to
amortization of bond premium may under some circumstances, result in the
Unitholder realizing taxable gain when his Units are sold or redeemed for an
amount equal to or less than his original cost. 

Foreign Investors. A Unitholder who is a foreign investor (i.e., an investor
other than a U.S. citizen or resident or a U.S. corporation, partnership,
estate or trust) will not be subject to United States Federal income taxes,
including withholding taxes, on interest income (including any original issue
discount) on, or any gain from the sale or other disposition of, his pro rata
interest in any Obligation or the sale of his Units provided that all of the
following conditions are met: (i) the interest income or gain is not
effectively connected with the conduct by the foreign investor of a trade or
business within the United States, (ii) either (a) the interest is not from
sources within the United States or (b) the interest is United States source
income (which is the case for most securities issued by United States
issuers), the Obligation is issued after July 18, 1984 (which is the case for
each Obligation held by the Trust), the foreign investor does not own,
directly or indirectly, 10% or more of the total combined voting power of all
classes of voting stock of the issuer of the Obligation and the foreign
investor is not a controlled foreign corporation related (within the meaning
of Section 864(d)(4) of the Code) to the issuer of the Obligation, (iii) with
respect to any gain, the foreign investor (if an individual) is not present in
the United States for 183 days or more during his or her taxable year and (iv)
the foreign investor provides all certification which may be required of his
status (foreign investors may contact the Sponsor to obtain a Form W-8 which
must be filed with the Trustee and refiled every three calendar years
thereafter). Foreign investors should consult their tax advisers with respect
to United States tax consequences of ownership of Units. 

It should be noted that the Tax Act includes a provision which eliminates the
exemption from United States taxation, including withholding taxes, for
certain "contingent interest." The provision applies to interest
received after December 31, 1993. No opinion is expressed herein regarding the
potential applicability of this provision and whether United States taxation
or withholding taxes could be imposed with respect to income derived from the
Units as a result thereof. Unitholders and prospective investors should
consult with their tax advisers regarding the potential effect of this
provision on their investment in Units. 

General. Each Unitholder (other than a foreign investor who has properly
provided the certifications described above) will be requested to provide the
Unitholder's taxpayer identification number to the Trustee and to certify that
the Unitholder has not been notified that payments to the Unitholder are
subject to back-up withholding. If the proper taxpayer identification number
and appropriate certification are not provided when requested, distributions
by the Trust to such Unitholder will be subject to back-up withholding. 

In the opinion of Tanner Propp & Farber, special counsel to the Trust for New
York tax matters, the Trust is not an association taxable as a corporation and
the income of such Trust will be treated as the income of the Unitholders
under the existing income tax laws of the State and City of New York. 

The foregoing discussion relates only to United States Federal and New York
State and City income taxes; Unitholders may be subject to state and local
taxation in other jurisdictions (including a foreign investor's country of
residence). Unitholders should consult their tax advisers regarding potential
state, local, or foreign taxation with respect to the Units. 

ACCRUED INTEREST 

Accrued Interest. Accrued interest is an accumulation of unpaid interest on
securities which generally is paid semi-annually, although the Trust accrues
such interest daily. Because of this, the Trust always has an amount of
interest earned but not yet collected by the Trustee. For this reason, with
respect to sales settling subsequent to the First Settlement Date, the Public
Offering Price of Units will have added to it the proportionate share of
accrued interest to the date of settlement. Unitholders will receive on the
next distribution date of the Trust the amount, if any, of accrued interest
paid on their Units. 

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 "Rights of
Unitholders--Distributions of Interest and Principal". 

Because of the varying interest payment dates of the Obligations, 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 offering prices of
the Obligations in the Trust and includes a sales charge of 4.9% of the Public
Offering Price (5.152% of the aggregate offering price of the Obligations).
However, the sales charge applicable to quantity purchases is, during the
initial offering period, reduced on a graduated basis to any person acquiring
100 or more Units as follows:



<TABLE>
<CAPTION>
Aggregate Number of Units Purchased    Dollar Amount of Sales 
                                      Charge Reduction Per Unit 
<S>                                      <C>      
100-249 Units                            $ 4.00    
250-499 Units                            $ 6.00    
500-999 Units                            $14.00    
1,000 or more Units                      $19.00   
</TABLE>


 

In the secondary market, Units are offered at the Public Offering Price which
is based on the bid prices of all the Obligations and includes a sales charge
determined in accordance with the table set forth below and is based upon the
dollar weighted average maturity of the Trust, plus accrued interest. For
purposes of computation, Obligations will be deemed to mature on their
expressed maturity dates unless: (a) the Obligations have been called for
redemption or funds or securities have been placed in escrow to redeem them on
an earlier call date, in which case such call date will be deemed to be the
date upon which they mature; or (b) such Obligations are subject to a 
"mandatory tender" , in which case such mandatory tender will be deemed to
be the date upon which they mature. The effect of this method of sales charge
computation will be that different sales charges rates will be applied to the
Trust based upon the dollar weighted average maturity of such Trust's
portfolio, in accordance with the following schedule: 



<TABLE>
<CAPTION>
               
Years To Maturity  Sales Charge  Years To Maturity   Sales Charge       
<S>                <C>           <C>                 <C>

2 .................2.041         10 .................4.932

8 .................4.493         16 to 30 ...........6.045     
</TABLE>




The sales charges in the above table are expressed as a percentage of the
aggregate bid prices of the Obligations in the Trust. Expressed as a percent
of the Public Offering Price, the sales charge on the Trust consisting
entirely of a portfolio of Obligations with 15 years to maturity would be
5.10%. 

Employees of Van Kampen American Capital Distributors Inc. and its
subsidiaries 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 Trust at the current Public Offering
Price less the underwriting commission or the dealer's concession in the
absence of an underwriting commission. Registered representatives of selling
brokers, dealers, or agents may purchase Units of the Trust at the current
Public Offering Price less the dealer's concession during the initial offering
period and for secondary market transactions. 

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 date 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. 

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 "Unit Distribution" 
below) 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
accordance with fluctuations in the prices of the underlying Obligations in
the Trust. 

As indicated above, the price of the Units as of 8:00 A.M. Central time or the
opening of business on the date the Obligations were deposited in the Trust
was determined by adding to the determination of the aggregate offering price
of the Obligations an amount equal to 5.152% of such value and dividing the
sum so obtained by the number of Units outstanding. This computation produced
a gross underwriting profit equal to 4.9% of the Public Offering Price. Such
price determination as of 8:00 A.M. Central time or the opening of business on
the Date of Deposit was made on the basis of an evaluation of the Obligations
in the Trust prepared by Interactive Data Services, Inc., a firm regularly
engaged in the business of evaluating, quoting or appraising comparable
securities. Except on the Date of Deposit during the period of initial
offering, the Evaluator will appraise or cause to be appraised daily the value
of the underlying Obligations as of 4:00 P.M. Eastern time on days the New
York Stock Exchange is open and will adjust the Public Offering Price of the
Units commensurate with such appraisal. Such Public Offering Price will be
effective for all orders received at or prior to 4:00 P.M. Eastern time on
each such day. Orders received by the Trustee, Sponsor or any Underwriter for
purchases, sales or redemptions after that time, or on a day when the New York
Stock Exchange is closed, will be held until the next determination of price.
For secondary market sales the Public Offering Price per Unit will be equal to
the aggregate bid price of the Obligations 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 Obligations and dividing the sum so attained by
the number of Units then outstanding. This computation produces a gross
underwriting profit equal to such sales charge expressed as a percentage of
the Public Offering Price. For secondary market purposes such appraisal and
adjustment will be made by the Evaluator as of 4:00 P.M. Eastern time on days
on which the New York Stock Exchange is open for each day on which any Unit of
the Trust is tendered for redemption, and it shall determine the aggregate
value of such Trust as of 4:00 P.M. Eastern time on such other days as may be
necessary. 

The aggregate price of the Obligations in the Trust has been and will be
determined on the basis of bid prices or offering prices, as appropriate, (a)
on the basis of current market prices for the Obligations obtained from
dealers or brokers who customarily deal in bonds comparable to those held by
the Trust; (b) if such prices are not available for any particular
Obligations, on the basis of current market prices for comparable bonds; (c)
by causing the value of the Obligations to be determined by others engaged in
the practice of evaluation, quoting or appraising comparable bonds; or (d) by
any combination of the above. Unless the Obligations 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 the Trust. 

The Evaluator will consider in its evaluation of Obligations which are in
default in payment of principal or interest or, in the Sponsor's opinion, in
significant risk of such default (the "Defaulted Obligations") 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 Obligations 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 Defaulted Obligations not covered by Permanent Insurance. In addition,
the Evaluator will consider the ability of the Portfolio Insurer involved to
meet its commitments under the Trust's 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 Obligations and the insurance
obtained by the 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 the Trust as of the date
of this Prospectus. 

The initial or primary Public Offering Price of the Units and the Sponsor's
initial repurchase price per Unit are based on the offering price per Unit of
the underlying Obligations plus the applicable sales charge and interest
accrued but unpaid from the First Settlement Date to the date of settlement.
The secondary market Public Offering Price and the Redemption Price per Unit
are based on the bid price per Unit of the Obligations in the Trust plus the
applicable sales charge plus accrued interest. The offering price of
Obligations in the Trust may be expected to range from .35%-1% more than the
bid price of such Obligations. On the Date of Deposit, the offering side
evaluation of the Obligations in the Trust were higher than the bid side
evaluation of such Obligations by the amount indicated under footnote (5) in
"Notes to Portfolio". 

Although payment is normally made three business days following the order for
purchase, payment may be made prior thereto. However, delivery of certificates
representing Units so ordered will be made three business days following such
order or shortly thereafter. 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. 

Unit Distribution. During the initial offering period, Units will be
distributed to the public by Underwriters, broker-dealers and others (see 
"Underwriting" ) at the Public Offering Price, plus accrued interest
computed as described above under "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 in the manner described. 

The Sponsor intends to qualify the Units for sale in a number of states.
Broker-dealers or others will be allowed a concession or agency commission in
connection with the distribution of Units during the initial offering period
of $30.00 per Unit for less than 100 Units, $36.00 per Unit for any single
transaction of 100 to 249 Units, $38.00 per Unit for any single transaction of
250 to 499 Units, $39.00 per Unit for any single transaction of 500 to 999
Units and $39.00 per Unit for any single transaction of 1,000 or more Units,
provided that such Units are acquired either from the Sponsor (in the case of
dealer transactions) or through the Sponsor (in the case of transactions
involving brokers or others). The increased concession or agency commission is
a result of the discount given to purchasers for quantity purchases. See 
"Public Offering--General" . Certain commercial banks are making Units of
the Trust available to their customers on an agency basis. A portion of the
sales charge (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 Trust; 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 "General" above) 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 "Public
Offering--General." 

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

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

Sponsor and Underwriter Compensation. The Underwriters through the initial or
primary distribution of Units will receive a gross sales commission equal to
4.9% of the Public Offering Price of the Units (5.152% of the net amount
invested), less any reduced sales charge for quantity purchases as described
under "General" above. 

The Sponsor will receive from the Underwriters the excess of such gross sales
commission over $35.00 per Unit as of the Date of Deposit. In connection with
quantity sales to purchasers of the 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. See 
"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 is underwrites. In addition, the Sponsor and
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
Obligations by the Sponsor and the cost of such Obligations to the Trust
(which is based on the determination of the aggregate offering price of the
Obligations in such Trust on the Date of Deposit as prepared by Interactive
Data Services, Inc.). See "Underwriting" and "Portfolio" . The
Sponsor and the Underwriters may also realize profits or sustain losses with
respect to Obligations deposited in a Trust which were acquired by the Sponsor
from underwriting syndicates of which they were members. The Sponsor has not
participated as sole underwriter or as manager or as a member of any
underwriting syndicates from which any of the Obligations in the portfolio of
the Trust 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 Obligations in the 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 commission that are available to the
Underwriter. 

As stated under "Public Market" below, the Sponsor intends to, and
certain of the other Underwriters may, maintain a secondary market for the
Units of the Trust. In so maintaining a market, the Sponsor or any such
Underwriters 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
Obligations in the Trust and includes a sales charge). In addition, the
Sponsor or any such Underwriters 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. 

Public Market. During the initial public offering period, the Sponsor and/or
certain of the other Underwriters intend to offer to purchase Units at a price
based on the aggregate offering price per Unit of the Obligations in the Trust
and the amount of accrued interest to the date of settlement less the related
sales commission. Afterward, although they are not obligated to do so, the
Sponsor intends to, and certain of the other Underwriters may, maintain a
market for the Units offered hereby and to offer continuously to purchase such
Units at prices, subject to change at any time, based upon the aggregate bid
prices of the Obligations in the portfolio plus interest accrued to the date
of settlement 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 other 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 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 Obligations in the portfolio plus any accrued
interest. The aggregate bid prices of the underlying Obligations in the Trust
are expected to be less than the related aggregate offering prices. See "
Rights of Unitholders--Redemption of Units" . A Unitholder who wishes to
dispose of his Units should inquire of his broker as to current market prices
in order to determine whether there is in existence any price in excess of the
Redemption Price and, if so, the amount thereof. 

RIGHTS OF UNITHOLDERS 

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

Although no such charge is now made or contemplated, the Trustee may require a
Unitholder to pay a reasonable fee for each certificate reissued 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. 

Distributions of Interest and Principal. Interest received by the Trust,
including that part of the proceeds of any disposition of Obligations which
represents accrued interest and any insurance proceeds representing interest
due on defaulted Obligations, is credited by the Trustee to the Interest
Account. Other receipts are credited to the Principal Account. Interest
received by the Trust 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") will be distributed on or shortly after the
fifteenth day of each month on a pro rata basis to Unitholders of record as of
the preceding record date (which will be the first day of the month). All
distributions will be net of applicable expenses. The pro rata share of cash
in the Principal Account will be computed on the date indicated under "
"Distribution Options" on page 2, 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 fifteenth day of such month. Proceeds received
from the disposition of any of the Obligations 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 the Principal or Interest Accounts
(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 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 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 Unitholders' pro rata share of the estimated net annual unit income in
the Interest Account after deducting estimated expenses attributable as is
consistent with the distribution plan chosen. Because interest payments are
not received by the Trust at a constant rate throughout the year, such
interest distribution may be more or less than the amount credited to the
Interest Account as of the record date. For the purpose of minimizing
fluctuation in the distributions from the 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 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
purchase, under the applicable plan of distribution. Notification to the
Trustee of the transfer of Units is the responsibility of the purchaser, but
in the normal course of business such notice is provided by the selling
broker-dealer. 

As of the first day of each month, the Trustee will deduct from the Interest
Account and, to the extent funds are not sufficient therein, from the
Principal Account, amounts necessary to pay the expenses of the Trust (as
determined on the basis set forth under "Trust Operating 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 Trust. Amounts so withdrawn shall not be considered a part of the
Trust'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 Obligations and redemption of
Units by the Trustee. 

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.

Reinvestment Option. Unitholders of the Trust may elect to have each
distribution of interest income, capital gains and/or principal on their Units
automatically reinvested in shares of any of the mutual funds listed under
"Trust Administration--Sponsor" 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 Trust. 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, IL 60181.
Texas residents who desire to reinvest may request that a broker-dealer
registered in Texas send the prospectus relating to the respective fund. 

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

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

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

Reports Provided. The Trustee shall furnish Unitholders in connection with
each distribution a statement of the amount of interest and, if any, the
amount of other receipts (received since the preceding distribution) being
distributed expressed in each case as a dollar amount representing the pro
rata share of each Unit outstanding. For as long as the Trustee deems it to be
in the best interests of the Unitholders, the accounts of the 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 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 a statement (i)
as to the Interest Account: interest received (including amounts representing
interest received upon any disposition of the Obligations), deductions for
applicable taxes and for fees and expenses of the Trust (including insurance
costs), for purchases of Replacement Obligations 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 Obligations and the net proceeds received therefrom
(excluding any portion representing accrued interest and the premium and any
expenses related thereto attributable to the exercise of the right to obtain
Permanent Insurance), the amount paid for purchases of Replacement Obligations
and for redemptions of Units, if any, deductions for payment of applicable
taxes, fees and expenses of the Trust 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 Obligations 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
Obligations in the Trust furnished to it by the Evaluator. 

Each distribution statement 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. 

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 4:00 P.M. Eastern time on days of trading on the New York
Stock Exchange, the date of tender is the next day on which such Exchange is
open for trading and such Units will be deemed to have been tendered to the
Trustee on such day for redemption at the redemption price computed on that
day. 

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

Accrued interest paid on redemption shall be withdrawn from the Interest
Account or, if the balance therein is insufficient, from the Principal
Account. All other amounts will be withdrawn from the Principal Account. The
Trustee is empowered to sell underlying Obligations 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 Obligations in
the Trust, while the initial and primary Public Offering Price of Units will
be determined on the basis of the offering price of the Obligations, as of
4:00 P.M. Eastern time on days of trading on the New York Stock Exchange on
the date any such determination is made. On the Date of Deposit, the Public
Offering Price per Unit (which is based on the offering prices of the
Obligations and includes the sales charge) exceeded the value at which Units
could have been redeemed (based upon the current bid prices of the Obligations
in such Trust) by the amount shown under "Summary of Essential Financial
Information" . While the Trustee has the power to determine the Redemption
Price per Unit when Units are tendered for redemption, such authority has been
delegated to the Evaluator which determines the price per Unit on a daily
basis. The Redemption Price per Unit is the pro rata share of each Unit in the
Trust determined on the basis of (i) the cash on hand in such Trust or monies
in the process of being collected, (ii) the value of the Obligations in such
Trust based on the bid prices of the Obligations, except for those cases in
which the value of insurance has been included and (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 Obligations in the 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 by the Trust on the Obligations in such Trust
unless such Obligations 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 Trust, see "
Public Offering--Offering Price". 

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 Obligations
represented by the Units so redeemed. As stated above, the Trustee may sell
Obligations to cover redemptions. When Obligations are sold, the size and
diversity of the affected Trust will be reduced. Such sales may be required at
a time when Obligations would not otherwise be sold and might result in lower
prices than might otherwise be realized. Pursuant to an irrevocable commitment
of the Portfolio Insurers, the Trustee upon the sale of an Obligation has the
right to obtain permanent insurance for such Obligation upon the payment of a
single predetermined insurance premium and any expenses related thereto from
the proceeds of the sale of such Obligation. Accordingly, any Obligation may
be sold on an insured basis. 

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
Obligations in the Trust 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. 

TRUST ADMINISTRATION 

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. 

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 Obligations designated by
the Evaluator as the Trustee in its sole discretion may deem necessary. The
Evaluator, in designating such Obligations, will consider a variety of
factors, including (a) interest rates, (b) market value and (c) marketability.
To the extent that Obligations are sold which are current in payment of
principal and interest in order to meet redemption requests and defaulted
Obligations are retained in the portfolio in order to preserve the related
insurance protection applicable to said Obligations, the overall quality of
the Obligations remaining in a Trust's portfolio will tend to diminish. The
Sponsor is empowered, but not obligated, to direct the Trustee to dispose of
Obligations 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 Obligations to issue new obligations in exchange or
substitution for any Obligation 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 Obligation or (2)
in the written opinion of the Sponsor the issuer will probably default with
respect to such Obligation 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 Obligations originally deposited thereunder. Within five days after the
deposit of obligations in exchange or substitution for underlying Obligations,
the Trustee is required to give notice thereof to each Unitholder, identifying
the Obligations eliminated and the Obligations substituted therefor. Except as
stated herein and under "Trust Portfolio--Replacement Obligations" 
regarding the substitution of Replacement Obligations for Failed Obligations,
the acquisition by the Trust of any obligations other than the Obligations
initially deposited is not permitted. 

If any default in the payment of principal or interest on any Obligation
occurs and no provision for payment is made therefor either pursuant to the
portfolio insurance, or otherwise, 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 Obligation within 30 days after notification by the
Trustee to the Sponsor of such default, the Trustee may in its discretion sell
the defaulted Obligation and not be liable for any depreciation or loss
thereby incurred. 

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 obligations either in addition to or in
substitution for any of the Obligations initially deposited in the Trust,
except for the substitution of certain refunding obligations for such
Obligations. 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 representing
51% of the Units of the Trust then outstanding or by the Trustee when the
value of the Trust, as shown by any semi-annual evaluation, is less than that
indicated under "Summary of Essential Financial Information" . 

A Trust will be liquidated by the Trustee in the event that a sufficient
number of Units not yet sold are tendered for redemption by the Underwriters,
including the Sponsor, so that the net worth of the Trust would be reduced to
less than 40% of the initial principal amount of the Trust. If the 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 the Trust shall terminate upon the
redemption, sale or other disposition of the last Obligation held in the
Trust, but in no event shall it continue beyond the end of the year preceding
the fiftieth anniversary of the Trust Agreement. In the event of termination
of the Trust, written notice thereof will be sent by the Trustee to each
Unitholder of the Trust at his address appearing on the registration books of
the Trust maintained by the Trustee, such notice specifying the time or times
at which the Unitholder may surrender his certificate or certificates for
cancellation. Within a reasonable time thereafter the Trustee shall liquidate
any Obligations then held in the Trust and shall deduct from the funds of the
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 Obligations 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 Obligations 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 Unitholders 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. 

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 negligence (gross negligence in the case of the Sponsor) 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 Obligations. In the event of the failure of the Sponsor to act under the

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 Trust as provided therein
or (iii) continue to act as Trustee without terminating the Trust Agreement. 

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

The duties of the Trustee are primarily ministerial in nature. It did not
participate in the selection of Obligations for the portfolio of the Trust. 

In accordance with the Trust Agreement, the Trustee shall keep proper books of
record and account of all transactions at its office for the Trust. Such
records shall include the name and address of, and the certificates issued by
the Trust to, every Unitholder of the Trust. Such books and records shall be
open to inspection by any Unitholder at all reasonable times during 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 "Rights of Unitholders--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 Obligations held in the Trust. 

Under the Trust Agreement, the Trustee or any successor trustee may resign and
be discharged of the Trust 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
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.

Units may also be sold to broker-dealers and others at prices representing the
per Unit concession or agency commission stated under "Public
Offering--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 Trust, the Agreement Among Underwriters provides that the
Sponsor will share on a pro rata basis among those Underwriters who underwrite
at least 250 Units 50% of the aggregate gain, if any, represented by the
difference between the Sponsor's cost of the Securities in connection with
their acquisition and the evaluation thereof on the Date of Deposit less
deductions for certain accrued interest and certain other costs. See "
Public Offering--Sponsor and Underwriter Compensation" and "
Portfolio". 

Underwriters and broker-dealers of the Trust, 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 registered 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 person 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 Trust. Such payments are
made by the Sponsor out of its own assets, and not out of the assets of the
Trust. These programs will not change the price Unitholders pay for their
Units or the amount that the Trust 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. 

OTHER MATTERS 

Legal Opinions. The legality of the Units offered hereby has been passed upon
by Chapman and Cutler, 111 West Monroe Street, Chicago, Illinois 60603, as
counsel for the Sponsor. Tanner Propp & Farber, 99 Park Avenue, New York, New
York 10016 has acted as counsel for the Trustee and as special counsel for the
Trust for New York tax matters. 

Independent Certified Public Accountants. The statement of condition and the
related portfolio 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. 

DESCRIPTION OF OBLIGATION RATINGS

Standard & Poor's, A Division of the McGraw-Hill Companies. A brief
description of the applicable Standard & Poor's rating symbols and their
meanings follows: 

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 may take into consideration obligors such as
guarantors, insurers or lessees. 

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

The ratings are based on current information furnished by the issuer and
obtained by Standard & Poor's from other sources it considers reliable.
Standard & Poor's does not perform an audit in connection with any rating and
may, on occasion, rely on unaudited financial information. The ratings may be
changed, suspended, or withdrawn as a result of changes in, or unavailability
of, such information, or for other circumstances. 

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--Bonds rated AAA have the highest rating assigned by Standard & Poor's to
a debt obligation. Capacity to pay interest and repay principal is extremely
strong. 

AA--Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in small degree. 

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

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 bonds in this category than for bonds in higher rated
categories. 

Plus (+) or Minus (-): 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: The symbol "(p)" indicates that the rating is
provisional. A provisional rating assumes the successful completion of the
project being financed by 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 of the project, makes no comment on
the likelihood of, or the risk of default upon failure of, such completion.
The investor should exercise his own judgment with respect to such likelihood
and risk. 

Moody's Investors Service, Inc. A brief description of the applicable Moody's
Investors Service, Inc. rating symbols and their meanings follow: 

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 lower 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. The market value of Baa-rated bonds is more sensitive to changes in
economic circumstances, and aside from occasional speculative factors applying
to some bonds of this class, Baa market valuations move in parallel with Aaa,
Aa and A obligations during periods of economic normalcy, except in instances
of oversupply. 

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

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

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS 

To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of Van Kampen American Capital Insured Income Trust,
Series 50: 

We have audited the accompanying statement of condition and the related
portfolio of Van Kampen American Capital Insured Income Trust, Series 50 as of
September 6, 1995. The statement of condition and portfolio are the
responsibility of the Sponsor. Our responsibility is to express an opinion on
such financial statements based on our audit. 

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of an irrevocable letter of credit deposited
to purchase 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 Van Kampen American Capital
Insured Income Trust, Series 50 as of September 6, 1995, in conformity with
generally accepted accounting principles.

<FN>
<F1>The aggregate value of the Obligations listed under "Portfolio" and
their cost to the Trust are the same. The value of the Obligations is
determined by Interactive Data Services, Inc. on the bases set forth under
"Public Offering--Offering Price" . The contracts to purchase
Obligations are collateralized by an irrevocable letter of credit of
$9,215,969 which has been deposited with the Trustee. Of this amount
$9,086,848 relates to the offering price on $9,425,000 principal amount of
Obligations to be purchased, and $129,121 relates to accrued interest on such
Obligations to the expected dates of delivery. 

<F2> Insurance coverage providing for the timely payment, when due (as more fully
set forth under "Insurance on the Obligations" ), of all principal and
interest on the Obligations in the portfolio of the Trust has been obtained by
the Trust except for Obligations in the Trust for which insurance has been
obtained by the issuer of the Obligation. Such insurance does not guarantee
the market value of the Obligations or the value of the Units. The insurance
obtained by the Trust is effective only while the Obligations are held in such
Trust, however, insurance obtained by an Obligation issuer is effective so
long as such Obligation is outstanding. Neither the bid nor offering prices of
the underlying Obligations or of the Units, absent situations in which the
Obligations 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 the Trust.

<F3>The aggregate public offering price (exclusive of interest) and the aggregate
sales charge are computed on the bases set forth under "Public
Offering--Offering Price" and "Public Offering--Sponsor and
Underwriter Compensation" and assume all single transactions involve less
than 100 Units. For single transactions involving 100 or more Units, the sales
charge is reduced (see "Public Offering--General" ) resulting in an
equal reduction in both the Cost to investors and the Gross underwriting
commission while the Net interest to Unitholders remains unchanged. 

<F4>The Trustee will advance to each Trust the amount of net interest accrued to
September 11, 1995, the First Settlement Date, for distribution to the Sponsor
as the Unitholder of record as of the First Settlement Date.

All of the Obligations in the portfolio are insured either by one of the
Preinsured Obligation Insurers (as indicated in the obligation name) or under
a portfolio insurance policy obtained by the Trust from AMBAC Indemnity or
CapMAC. Obligations that are insured under a portfolio insurance policy
obtained by the Trust from CapMAC are marked by a "/". See 
"Insurance on the Obligations". 

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

   
NOTES TO PORTFOLIO: As of the Date of Deposit: September 6, 1995

(1)All Obligations 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, Obligations 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 Obligations.
Contracts to acquire Obligations were entered into during the period from
August 30,1995 to September 5,1995. These Obligations have expected settlement
dates of September 6,1995 (see "Trust Portfolio"). 
    
(2)All ratings are by Standard & Poor's unless otherwise indicated. "*" 
 indicates that the rating of the Obligation is by Moody's Investors Service,
Inc. The ratings represent the latest published ratings by the respective
ratings agency. "Y" indicates that such rating is contingent upon
physical receipt by the respective ratings agency of a policy of insurance
obtained by the issuer of the bonds involved and issued by the Preinsured Bond
Insurer named in the bond's title. A commitment for insurance in connection
with these bonds has been issued by the Preinsured Bond Insurer named in the
bond's title. "N/R" indicates that the applicable rating service did
not provide a rating for that particular Obligation. For a brief description
of the rating symbols and their related meaning, see "Description of
Obligation Ratings". 

(3)There is shown under this heading the year in which each issue of the
Obligations is initially or currently callable and the call price for that
year. Each issue of the Obligations 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
the Obligations. Redemption pursuant to call provisions generally will, and
redemption pursuant to sinking fund provisions may, occur at times when the
redeemed bonds have an offering side valuation which represents a premium over
par. Certain Obligations may be subject to redemption without premium prior to
the date shown pursuant to extraordinary optional or mandatory redemptions if
certain events occur. Notwithstanding any provisions to the contrary, certain
bond issuers have in the past and others may in the future, attempt to redeem
bonds prior to their initially scheduled call dates and at prices which do not
include any premiums. For a general discussion of certain of these events, see
"Trust Portfolio--Redemptions of Obligations". To the extent that the
Obligations were deposited in the Trust at a price higher than the price at
which they are redeemed, this will represent a loss of capital when compared
with the original Public Offering Price of the Units. Conversely, to the
extent that the Obligations were acquired at a price lower than the redemption
price, this will represent an increase in capital when compared with the
original Public Offering Price of the Units. Distributions will generally be
reduced by the amount of the income which would otherwise have been paid with
respect to redeemed Obligations 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 "Tax Status" and
"Estimated Current Return and Estimated Long-Term Return". 

(4)Evaluation of Obligations is made on the basis of current offering prices
for the Obligations. The offering prices are greater than the current bid
prices of the Obligations which is the basis on which Unit value is determined
for purposes of redemption of Units (see "Public Offering--Offering
Price"). 
   
(5)Other information regarding the Obligations in the Trust, as of the Date of
Deposit, is as follows:

</TABLE>


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

On the Date of Deposit, the offering side evaluation of the Obligations in the
Trust was higher than the bid side evaluation of such Obligations by 0.49% of
the aggregate principal amount of such Obligations. All contracts are expected
to be settled by the First Settlement Date for the purchase of Units. 

"#" indicates that such Obligation was issued at an original issue
discount. The tax effect of Obligations issued at an original issue discount
is described in "Tax Status". 

(6)This Obligation has been purchased at a deep discount from the par value
because there is little or no stated interest income thereon. Obligations
which pay no interest are normally described as "zero coupon" bonds.
Over the life of bonds purchased at a deep discount the value of such bonds
will increase such that upon maturity the holders of such bonds will receive
100% of the principal amount thereof. Approximately 5% of the aggregate
principal amount of the Obligations in the Trust are "zero coupon" 
bonds. 
    
(7)Standard & Poor's has assigned its "AAA" investment rating to all
of the Obligations while in the Trust, as insured by the Insurers. 

ESTIMATED CASH FLOWS TO UNITHOLDERS 

The table below sets forth the per Unit estimated distributions of interest
and principal to Unitholders. The table assumes no changes in Trust expenses,
no changes in the current interest rates, no exchanges, redemptions, sales,
prepayments or partial prepayments of the underlying Obligations 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.

interest on a Bond which is Due for Payment.

    (k)   "Due for Payment," when referring to principal of a Bond (or

maturity date has been reached, and does not refer to any earlier date on
which payment is due by reason of call for redemption, acceleration or

     This Policy cannot be cancelled by AMBAC.  The insurance provided by
this Policy shall remain in force throughout the Policy period.  This
Policy provides for payment to the Trustee as a result of Nonpayment of

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

which the Insured Instruments are Due for Payment.

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


4.   Rights of AMBAC

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

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

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

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


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


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


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


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


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

                                                Policy No. SB8315
     
   Capital Markets Assurance Corporation (the "Insurer"),inconsideration
of the payment of the premium and subject to the terms of this policy and
the letter agreement dated September 6, 1995 among the Insurer, the
Depositor and the Trustee, each as hereinafter defined, hereby unconditionally
and irrevocably guarantees to the Trust, as hereinafter defined, the full and
complete payment required to be made by or on behalf of the issuer(s) of the
Obligations, as hereinafter defined, to the applicable paying agent(s) for the
underlying obligations or its/their successor(s) (the "Paying Agent") of an
amount equal to (i) the principal of (either at the stated maturity or by any
advancement of maturity pursuant to a mandatory sinking fund payment) and
interest on the obligations described in Exhibit A attached hereto (referred
to herein as the "Obligations"), as such payments shall become due but shall
not be so paid in accordance with the original terms of the Obligations when
issued and without regard to any amendment or modification which affects in
any manner the amount, terms or conditions of payment of such Obligations
thereafter, unless the Insurer has previously consented in writing to any such
amendment or modification, except that in the event of any acceleration of the
due date of such principal by reason of mandatory or optional redemption or
acceleration resulting from a default (an "Acceleration Default"), a failure
to make any required principal and/or interest payment as and when due (after
giving effect to any applicable grace or cure period)(a "Payment Default")
or an event of bankruptcy, receivership, insolvency or similar action (a
"Bankruptcy Default"), other than any advancement of maturity pursuant to a
mandatory sinking fund payment, the payments guaranteed hereby may be made
by the Insurer at its option upon the earlier to occur of an Acceleration
Default, a Payment Default or a Bankruptcy Default within thirty (30) days
of notice of such Acceleration Default, Payment Default or Bankruptcy Default
(x) in such amounts and at such times as such payments would have been due had
there not been any such acceleration or (y) on such accelerated basis by payment
(an "Accelerated Payment") of an amount equal to the par value of such
Obligation plus accrued interest to the date of any such Accelerated Payment,
and (ii) the payment of any Insured Amount subsequently avoided in whole or in
part as a preference payment under applicable law. The amounts referred to in
the preceding sentence, including the Accelerated Payment, shall be referred to
herein collectively as the "Insured Amounts."
     
     Upon receipt of telegraphic or telecopied notice, such notice promptly
confirmed in writing by registered or certified mail, in the form of Exhibit B
hereto duly completed (such form to be sent and notice to be given for each
Obligation for which a claim is made under this policy), or upon receipt of
written notice by registered or certified mail in the form of Exhibit B hereto
duly completed (such form to be sent and notice to be given for each Obligation
for which a claim is made under this policy), by the Insurer or its designee
from the Trustee, that a Payment Default has occurred, the Insurer shall, on the
business day next succeeding the later of (x) the date which is thirty (30) days
after the date of any Payment Default or (y) receipt of the first notice of such
Payment Default with respect to such Obligation and, in the event the Insurer
does not make an Accelerated Payment, thereafter, within one (1) business day
after the later of (x) receipt of notice of a subsequent Payment Default or (y)
the due date of the Insured Amounts to which such notice relates, disburse to
the Trustee payment of the Insured Amounts due on such Obligation, less any
amount held by the Paying Agent or the Trustee for the payment of the Insured
Amounts and legally available therefor.  Notwithstanding the foregoing, in the
event a Bankruptcy Default or Acceleration Default occurs prior to any Payment
Default, the Insurer may, at its option, make an Accelerated Payment upon the
earlier to occur of such Bankruptcy Default or Acceleration Default within
thirty (30) days of such Bankruptcy Default or Acceleration Default.  In such
event, the Insurer shall have no further Obligation to make any payments in
respect of the Obligation for which such Accelerated Payment was made.  The
Trustee will be paid, as to principal or as to principal and interest, upon
presentment and surrender to the Insurer of each Obligation, or in the case of
any Obligation held by a depository (the "Depository") on behalf of the Trustee,
presentment and surrender of such Obligation through the Depository, or
presentment of such other proof of ownership of the Obligation registered,,
together with evidence satisfactory to the Insurer that, in all cases, such
Obligation is the Obligation described in this policy or any replacement or
successor hereto, and that such Obligation is free and clear of all claims and
encumbrances created by or on behalf of the Trustee and is uncancelled, and any
appropriate instruments of assignment to evidence the assignment of the Insured
Amounts due on the Obligation as are paid by the Insurer, such instruments being
in a form satisfactory to the Insurer.  This policy does not insure against loss
of any prepayment premium which may at any time be payable with respect to any
Obligation.
     
     If payment of any principal of or interest on the Obligations that is
avoided as a preference under applicable, bankruptcy, insolvency, receivership
or similar law in the event of a bankruptcy, insolvency, receivership or similar
action of the issuer of the Obligation is required to be made under this policy,
the Insurer will pay such amount as is avoided as a preference pursuant to the
Order or notice referred to below when due to be paid on a scheduled basis in
accordance with the original terms of the Obligations (without reference to any
redemption thereof) and in any event no earlier than the first to occur of the
fourth business day following receipt by the Insurer from the Trustee of (i)(x)
a certified copy of the order of the court, or such regulatory authority which
exercised jurisdiction, to the effect that the Trustee or the Depository is
required to return principal or interest paid on any Obligation during the term
of this policy because such payments were avoidable preferences under applicable
bankruptcy, insolvency, receivership or similar laws (the "Order") and (y) a
certificate of the Trustee that the Order has been entered and is not subject to
any stay or (ii) notice from the Trustee that such payment has been avoided and
the Depository holding the affected Obligation on behalf of the Trust has repaid
such avoided payment and/or charged or reduced the account of the Trustee by the
amount of such avoided payment (provided that if such certified copy and
certificate or notice referred to in clauses (i) and (ii) above are received
after 1:00 p.m., New York City time, on such business day, the Insurer shall
make such payment on the fifth business day following such date).  Such payment
shall be disbursed to the receiver, conservator, debtor-in-possession or trustee
in bankruptcy named in the Order and not to the Trustee directly in the event of
receipt of the certified copy and certificate referred to in clause (i) above
and to the Trustee in the event of receipt of the notice referred to in clause
(ii) above.
     
     Notwithstanding the foregoing or any other provisions of this policy, if
the Trustee receives notice that payment of any principal of or interest on any
of the Obligations is avoided as a preference under applicable bankruptcy,
insolvency, receivership or similar law and the Depository holding the affected
Obligation has not repaid such amount or charged or reduced the Trustee's
account for such amount, then the Trustee shall forward such notice to the
Insurer within four business days of the Trustee's receipt thereof.  The Insurer
shall have the option to commence any appropriate adversary proceeding, in which
case it shall be responsible for all costs and expenses in connection therewith
and shall indemnify and hold the Trustee harmless against any loss or liability
in connection therewith or the failure of the Trustee to make such preference
payment, or to pay the amount of such avoided payment to the receiver,
conservator, debtor-in-possession or trustee in bankruptcy named in such notice
in accordance with the preceding paragraph.
     
     After the Insurer has made payment with respect to an Obligation, it shall
be subrogated to all of the rights of the Trust thereon or in relation thereto
to the extent of such payment, including but not limited to the rights to
commence or participate in an adversary proceeding.  When the Insurer has made
any Accelerated Payment, and until the full amount of such payment has been
recovered, the Insurer shall be vested with all of the Trust's options, rights,
votes, powers and the like under all the legal proceedings by which each
Obligation has been authorized, issued or secured, including, the governing
statutes, resolutions and ordinances of the issuer of the Obligation, and any
trust indenture, mortgage, lease agreement or other contract relating to the
Obligation or its security.  The Insurer shall not be liable to the Trust for
any loss or damage resulting from the exercise or failure to exercise, in its
sole discretion, any of such options, votes, rights, powers and the like it may
have as holder or registered owner of an Obligation with respect to which it has
made any payment.  The Trustee shall execute and deliver instruments and do
whatever else may be required to secure the foregoing rights of the Insurer, and
will do nothing to prejudice them.
     
     The Obligations of the Insurer hereunder cannot be accelerated except at
the sole option of the Insurer.
     
     The term "Depositor" shall mean Van Kampen American Capital Distributors,
Inc. and its successors or any successor Depositor.
     
     The term "Trust" shall mean the Van Kampen American Capital Insured Income
Trust, Series 50, created pursuant to a trust agreement which 
incorporates by reference the Standard Terms and Conditions of Trust, effective
April 3, 1990, among the Depositor, the Trustee and American Portfolio 
Evaluation Services, as evaluator.
     
     The term "Trustee" shall mean The Bank of New York, or any successor
trustee or co-trustee.
     
     Any service of process on the Insurer may be made to the Insurer,
Attention: General Counsel, at its offices located at 885 Third Avenue, New
York, New York 10022, and such service or process shall be valid and binding.
     
     This policy shall only apply to Obligations held in and owned by the Trust
and held or owned by the Depository on behalf of the Trust and shall not apply
to any Obligations not deposited therein by the Depositor.  This policy shall
continue in force only with respect to Obligations held in and owned by the
Trust, and, subject to the provisions of this paragraph, the Insurer shall not
have any liability under this policy with respect to any Obligations which do
not constitute part of the Trust.  This policy is non-cancellable during the
term hereof for any reason, but shall terminate as to any Obligation which is no
longer held by the Trust and has been redeemed from or sold by the Trustee or
the Trust on the date of such redemption or on the settlement date of such sale,
and the Insurer shall not have any liability under this policy as to any such
Obligation thereafter.  Notwithstanding the foregoing provisions of this
paragraph, the termination of this policy as to any Obligation shall not affect
the Obligations of the Insurer regarding any other Obligation in the Trust.
This policy shall terminate as to all Obligations on the date on which the last
of the Obligations mature, are redeemed or are sold by the Trust.
     
     The premium on this policy is not refundable for any reason, including the

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

     Re:    Van Kampen American Capital Insured Income Trust
                               Series 50

Gentlemen:
     
     We   have   served  as  counsel  for  Van  Kampen  American  Capital
Distributors,  Inc.  as  Sponsor and Depositor  of  Van  Kampen  American
Capital Insured Income Trust, Series 50 (the "Fund"), in connection  with
the  preparation,  execution  and delivery of  a  Trust  Agreement  dated
September  6,  1995,  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 the Bonds listed in Schedule A 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 Fund 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  of  the
     Fund have been duly authorized; and
     
           2.    The  certificates evidencing the Units 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 the Fund and  the  Depositor  in
     accordance with the terms thereof.
     
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 33-62343) 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.

     Re:   Van Kampen American Capital Insured Income Trust,
                               Series 50

Gentlemen:
     
     We   have   acted  as  counsel  for  Van  Kampen  American   Capital
Distributors,  Inc.,  Depositor of Van Kampen  American  Capital  Insured
Income Trust, Series 50 (the "Trust"), in connection with the issuance of
Units  of  fractional  undivided interest in the  Trust,  under  a  Trust
Agreement  dated  September 6, 1995 (the "Indenture")  among  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
Prospectus, the Indenture, and such other instruments and documents as we
have deemed pertinent.
     
     The  assets  of the Trust will consist of a portfolio  of  long-term
corporate  debt obligations issued after July 18, 1984 of  United  States
corporate  issuers  (the  "Corporate  Bonds"),  municipal  issuers   (the
"Taxable  Municipal  Bonds") and "zero coupon" U.S. Treasury  bonds  (the
"Treasury Bonds") (collectively, the "Obligations") as set forth  in  the
Prospectus.   For  purposes  of the opinions set  forth  below,  we  have
assumed  that  interest  on  each  of  the  Taxable  Municipal  Bonds  is
includable  in  gross income for federal income tax purposes  (i.e.,  the
Taxable Municipal Bonds are not tax-exempt).
     
     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)    The Unitholder will be considered as owning a  pro  rata
     share of each asset of a Trust in the proportion that the number  of
     Units  held  by him bears to the total number of Units  outstanding.
     Under subpart E, subchapter J of chapter 1 of the Code, income of  a
     Trust will be treated as income of each Unitholder 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.   Each Unitholder will be considered to have  received  his
     pro  rata share of interest derived from each Trust asset when  such
     interest  is  received  by a Trust.  Each Unitholder  will  also  be
     required  to  include  in  taxable income  for  Federal  income  tax
     purposes,  original issue discount with respect to his  interest  in
     any  Obligation held by a Trust which was issued with original issue
     discount  at  the  same time and in the same manner  as  though  the
     Unitholder  were the direct owner of such interest.  Original  issue
     discount will be treated as zero with respect to Corporate Bonds and
     the Taxable Municipal Bonds if it is "de minimis" within the meaning
     of  Section  1273 of the Code and, based upon a Treasury  Regulation
     (the  "Regulation") which was issued on December 28, 1992  regarding
     the  stripped  bond rules of the Code, original issue discount  with
     respect  to  a Treasury Bond will be treated as zero if  it  is  "de
     minimis" as determined thereunder.  If a Corporate Bond is a  "high-
     yield  discount obligation" within the meaning of Section  163(e)(5)
     of  the  Code,  certain special roles may apply.  A  Unitholder  may
     elect  to include in taxable income for Federal income tax purposes,
     market  discount as it accrues with respect to his interest  in  any
     Corporate Bond or Taxable Municipal Bond held by a Trust which he is
     considered as having acquired with market discount at the same  time
     and  in  the  same manner as though the Unitholder were  the  direct
     owner of such interest.
     
       (iii)   The price a Unitholder pays for his Units, including sales
     charges,  is allocated among his pro rata portion of each Obligation
     held by a Trust (in proportion to the fair market values thereof  on
     the  date the Unitholder purchases his Units), in order to determine
     his initial cost for his pro rata portion of each Obligation held by
     a  Trust.   The  Treasury  Bonds are  treated  as  bonds  that  were
     originally  issued  at  an  original issue  discount.   Because  the
     Treasury  Bonds  represent  interests in  "stripped"  U.S.  Treasury
     bonds, a Unitholder's initial cost for his pro rata portion of  each
     Treasury  Bond held by a Trust (determined at the time  he  acquires
     his  units, in the manner described above) shall be treated  as  its
     "purchase  price"  by  the  Unitholder.   Under  the  special  rules
     relating  to  stripped bonds, original issue discount applicable  to
     the  Treasury Bonds is effectively treated as interest  for  Federal
     income  tax  purposes and the amount of original issue  discount  in
     this  case  is generally the difference between the bond's  purchase
     price  and  its stated redemption price at maturity.   A  Unitholder
     will  be  required to include in gross income for each taxable  year
     the   sum   of  his  daily  portions  of  original  issue   discount
     attributable to the Treasury Bonds held by a Trust as such  original
     issue  discount  accrues and will in general be subject  to  Federal
     income  tax with respect to the total amount of such original  issue
     discount  that accrues for such year even though the income  is  not
     distributed to the Unitholders during such year to the extent it  is
     greater  than  or equal to the "de minimis" amount described  below.
     To  the  extent  the  amount  of such  discount  is  less  than  the
     respective  "de minimis" amount, such discount shall be  treated  as
     zero.   In  general, original issue discount accrues daily  under  a
     constant  interest  rate method which takes into account  the  semi-
     annual compounding of accrued interest.  In the case of the Treasury
     Bonds, this method will generally result in an increasing amount  of
     income to the Unitholders each year.
     
         (iv)    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 Unit.  Before adjustment, such
     basis  would  normally be cost if the Unitholder  had  acquired  his
     Units by purchase.  In addition, such basis will be increased by the
     Unitholder's  aliquot share of the accrued original  issue  discount
     with  respect  to  each Obligation held by a Trust with  respect  to
     which  there was original issue discount at the time such Obligation
     was  issued and by accrued market discount which the Unitholder  has
     elected to annually include in income with respect to each Corporate
     Bond  and  Taxable  Municipal Bond and reduced by  the  Unitholder's
     aliquot  share of the amortized acquisition premium, if  any,  which
     the Unitholder has properly elected to amortize under Section 171 of
     the Code on each Obligation held by a Trust.  The tax cost reduction
     requirements  of the Code relating to amortization of  bond  premium
     may  under  some  circumstances, result in the Unitholder  realizing
     taxable gain when his Units are sold or redeemed for an amount equal
     to or less than his original cost.
     
         (v)   If the Trustee disposes of a Trust asset (whether by sale,
     exchange, redemption, payment on maturity or otherwise) gain or loss
     will be recognized to the Unitholder and the amount thereof will  be
     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 (as of the date  on  which
     his  Units  were  acquired) among each of the Trust  assets  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 Unitholder's share of the amortized acquisition premium,  if
     any,  on  Obligations  held by the Trust which  the  Unitholder  has
     properly elected to amortize under Section 171 of the Code and  must
     be increased by the Unitholder's share of the accrued original issue
     discount  with  respect to each Obligation which, at  the  time  the
     Obligation was issued, had original issue discount and in  the  case
     of  a  Corporate Bond or a Taxable Municipal Bond, by accrued market
     discount  which  the Unitholder has elected to annually  include  in
     income.
     
     The Tax Reform Act of 1986 (the "Act"), among other things, provides
that certain itemized deductions, such as investment expenses, tax return
preparation  fees  and employee business expenses will be  deductible  by
individuals  only  to  the  extent they exceed 2%  of  such  individual's
adjusted  gross  income.  Temporary regulations have  been  issued  which
require Unitholders to treat certain expenses of a Trust as miscellaneous
itemized deductions subject to this limitation.
     
     The  Code  provides a complex set of rules governing the accrual  of
original  issue discount, including special rules relating to  "stripped"
debt  instruments such as the Treasury Bonds.  These rules  provide  that
original  issue  discount generally accrues on the basis  of  a  constant
compound interest rate.  Special rules apply if the purchase price of  an
Obligation  exceeds its original issue price plus the amount of  original
issue  discount which would have previously accrued, based upon its issue
price (its "adjusted issue price").  Similarly, these special rules would
apply  to  a  Unitholder if the tax basis of his pro rata portion  of  an
Obligation  issued  with original issue discount  exceeds  his  pro  rata
portion of its adjusted issue price.  The application of these rules will
also  vary  depending  on  the value of the  Obligation  on  the  date  a
Unitholder  acquires his Units, and the price a Unitholder pays  for  his
Units.  In addition, as discussed above, the Regulation provides that the
amount  of original issue discount on a stripped bond is considered  zero
if  the actual amount of original issue discount on such stripped bond as
determined  under Section 1286 of the Code is less than  a  "de  minimis"
amount,  which,  the  Regulation provides, is the  product  of  (i)  0.25
percent of the stated redemption price at maturity and (ii) the number of
full  years  from  the  date the stripped bond is  purchased  (determined
separately for each new purchaser thereof) to the final maturity date  of
the  bond.  It is possible that a Corporate Bond that has been issued  at
an original issue discount may be characterized as a "high-yield discount
obligation" within the meaning of Section 163(e)(5) of the Code.  To  the
extent  that  such an obligation is issued at a yield in  excess  of  six
percentage  points over the applicable Federal rate,  a  portion  of  the
original  issue  discount on such obligation will be characterized  as  a
distribution  on  stock (e.g., dividends) for purposes of  the  dividends
received  deduction  which  is  available to  certain  corporations  with
respect to certain dividends received by such corporations.
     
     If a Unitholder's tax basis in his interest in any Corporate Bond or
Taxable Municipal Bond held by a Trust is less than his allocable portion
of  such  Bond's stated redemption price at maturity (or, if issued  with
original issue discount, his allocable portion of its revised issue price
on  the  date he buys his Units), such difference will constitute  market
discount  unless  the  amount  of market  discount  is  "de  minimis"  as
specified in the Code.  To the extent the amount of such discount is less
than  the respective "de minimis" amount, such discount shall be  treated
as  zero.   Market  discount accrues daily computed on  a  straight  line
basis,  unless the Unitholder elects to calculate accrued market discount
under a constant yield method.  The market discount rules do not apply to
Treasury  Bonds  because  they are stripped debt instruments  subject  to
special original issue discount rules as discussed in paragraph (iii).
     
     Accrued market discount is generally includible in taxable income of
the  Unitholders  as ordinary income for federal tax  purposes  upon  the
receipt  of  serial  principal payments on Corporate  Bonds  and  Taxable
Municipal Bonds held by a Trust, on the sale, maturity or disposition  of
such Bonds by the Trust and on the sale of a Unitholder's Units unless  a
Unitholder  elects  to  include the accrued market  discount  in  taxable
income  as  such  discount accrues.  If a Unitholder does  not  elect  to
annually include accrued market discount in taxable income as it accrues,
deductions of any interest expense incurred by the Unitholder to purchase
or  carry his Units will be reduced by such accrued market discount.   In
general, the portion of any interest which is not currently deductible is
deductible  when the accrued market discount is included in  income  upon
the  sale  or redemption of the Corporate Bonds or the Taxable  Municipal
Bonds or the sale of Units.
     
     A  Unitholder will recognize taxable gain (or loss) when all or part
of  the  pro rata interest in an Obligation is either sold by a Trust  or
redeemed  or  when  a  Unitholder disposes of  his  Units  in  a  taxable
transaction,  in each case for an amount greater (or less) than  his  tax
basis therefor.
     
     Any  gain  recognized on a sale or exchange and not  constituting  a
realization of accrued "market discount" and any loss will, under current
law, generally be capital gain or loss except in the case of a dealer  or
financial institution.  As previously discussed, gain attributable to any
Corporate Bond or Taxable Municipal Bond deemed to have been acquired  by
the Unitholder with market discount will be treated as ordinary income to
the extent the gain does not exceed the amount of accrued market discount
not previously taken into income.  The tax cost reduction requirements of
the  Code  relating  to amortization of bond premium may,  under  certain
circumstances, result in the Unitholder realizing a taxable gain when his
Units  are  sold  or redeemed for an amount equal to  or  less  than  his
original cost.
     
     If  a  Unitholder disposes of a Unit, he is deemed thereby  to  have
disposed  of  his entire pro rata interest in all trust assets  including
his  pro rata portion of all of the Corporate Bonds and Taxable Municipal
Bonds represented by the Unit.  This may result in a portion of the gain,
if  any,  on such sale being taxable as ordinary income under the  market
discount  rules  (assuming  no election was made  by  the  Unitholder  to
include market discount in income as it accrues) as previously discussed.
     
     A Unitholder who is a foreign investor (i.e., an investor other than
a  U.S.  citizen or resident or U.S. corporation, partnership, estate  or
trust)  will  not  be  subject  to United States  Federal  income  taxes,
including  withholding taxes on interest income (including  any  original
issue  discount)  on, or any gain from the sale or other  disposition  or
redemption  of any Obligation held by a Trust or the sale  of  his  Units
provided that all of the following conditions are met:
     
          (i)    the interest income or gain is not effectively connected
     with  the  conduct  by the foreign investor of a trade  or  business
     within the United States;
     
        (ii)   either
          
              (a)   the interest is United States source income (which is
          the  case for most securities issued by United States issuers),
          the debt instrument is issued after July 18, 1984 (which is the
          case  for  each  Obligation held by  the  Trust),  the  foreign
          investor does not own, directly or indirectly, 10% or  more  of
          the  total combined voting power of all classes of voting stock
          of  the issuer of the debt instrument and the Unitholder is not
          a controlled foreign corporation related (within the meaning of
          Section  864(d)(4)  of  the Code) to the  issuer  of  the  debt
          instrument; or
          
               (b)    the interest income is not from sources within  the
          United States;
     
        (iii)     with respect to any gain, the foreign investor  (if  an
     individual) is not present in the United States for 183 days or more
     during his or her taxable year; and
     
         (iv)   the foreign investor provides all certification which may
     be required of his status.
     
     It  should  be noted that the "Revenue Reconciliation Act of  1993,"
includes  a  provision which eliminates the exemption from United  States
taxation, including withholding taxes, for certain "contingent interest."
This provision applies to interest received after December 31, 1993.   No
opinion is expressed herein regarding the potential applicability of this
provision  and whether United States taxation or withholding taxes  could
be  imposed  with respect to income derived from the Units  as  a  result
thereof.
     
     The  scope  of this opinion is expressly limited to the matters  set
forth  herein,  and, except as expressly set forth above, we  express  no
opinion  with respect to any other taxes, including state or local  taxes
or  collateral  tax consequences with respect to the purchase,  ownership
and disposition of Units.

                                    Very truly yours

Van Kampen American Capital Insured
Income Trust, Series 50
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 Van Kampen American Capital
Insured  Income  Trust,  Series 50 (in the aggregate  ther  "Trusts"  and
individually  the "Trust") for purposes of determining the  applicability
of certain New York taxes under the circumstances hereinafter described.
     
     The   Trusts  are  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 Trusts  dated
today  to be filed as an amendment to a registration statement heretofore
filed  with the Securities and Exchange Commission (file number 33-62343)
under  the Securities Act of 1933, as amended (the "Prospectus"  and  the
"Registration  Statement"),  the  objectives  of  the  Trusts   are   the
generation  of  a  high level of current income and the  conservation  of
capital  through a diversified investment in a fixed portfolio  primarily
consisting of corporate debt securities.  It is noted that no opinion  is
expressed herein with regard to the Federal tax aspects of the bonds, the
Trusts,  units  of  the Trusts (the "Units"), or any interest,  gains  or
losses in respect thereof
     
     As  more fully set forth in the Indenture and in the Prospectus, the
activities of the Trustee will include the following:
     
     On  the Date of Deposit, the Depositor will deposit with the Trustee
as  regards  the  Trusts the total principal amount of  interest  bearing
obligations  and/or contracts for the purchase thereof together  with  an
irrevocable  letter  of credit in the amount required  for  the  purchase
price  and  accrued interest, if any, along with the policy purchased  by
the  Depositor  evidencing  insurance  guaranteeing  timely  payment   of
principal  and interest on some of the obligations comprising the  corpus
of  the  Trusts  as  more  fully set forth  in  the  Prospectus  and  the
Registration  Statement.  All other obligations included in  the  deposit
described  above will be covered by insurance obtained by the  issuer  of
such obligations or by a prior owner, which may be the Depositor prior to
the  Date  of  Deposit,  guaranteeing timely  payment  of  principal  and
interest, or will be U.S. Treasury obligations.
     
     We understand that all insurance policies described in the preceding
paragraph,  whether  purchased by the Depositor, a  prior  owner  or  the
issuer,  provide, or wig 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 Trusts, and, upon the  receipt  thereof,  will
deliver to the Depositor registered certificates for the number of  Units
representing the entire capital of the Trust 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 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  the  Trust and with the proceeds from  the  disposition  of
obligations  held in the Trust and the distribution of such interest  and
proceeds to the Unit holders.  The Trustee will also maintain records  of
the  registered holders of Certificates representing an interest  in  the
Trust  and administer the redemption of Units by such Certificate holders
and  may  perform  certain administrative functions with  respect  to  an
automatic reinvestment option and a conversion option.
     
     Generally, obligations held in the Trust 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 Trust, such  as  default  by  the
issuer  in  payment of interest or principal on the obligations,  and  no
provision  for payment is made therefor either pursuant to the  portfolio
insurance  or  otherwise, and the Sponsor fails to instruct the  Trustee,
within thirty (30) days after notification, to hold such obligation.
     
     Prior  to the termination of the Trust, the Trustee is empowered  to
sell  Bonds, on a list furnished by the Sponsor, only for the purpose  of
redeeming Units tendered to it and of paying expenses for which Trust are
not  available.   The  Trustee  does not  have  the  power  to  vary  the
investment  of  any Unit holder in the Trust, and under no  circumstances
may the proceeds of sale of any obligations held by the Trust 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:
     
     Any business conducted by a trustee or trustees in which interest or
ownership  is  evidenced  by  certificate  or  other  written  instrument
includes, but is not limited to, an association commonly referred to as a
"business  trust"  or  "Massachusetts trust".  In determining  whether  a
trustee  or trustees are conducting a business, the form of the agreement
is  of significance but is not controlling.  The actual activities of the
trustee  or trustees, not their purposes and powers, will be regarded  as
decisive  factors in determining whether a trust is subject to tax  under
article  9-A.  The mere investment of Trust and the collection of  income
therefrom, with incidental replacement of securities and reinvestment  of
Trust,  does not constitute the conduct of a business in the  case  of  a
business  conducted by a trustee or trustees. 20 NYCRR 1-2.3(b)(2)  (July
11, 1990).
     
     New  York cases dealing with the question of whether a trust win  be
subject  to the franchise tax have also delineated the general rule  that
where  a  trustee  merely invests Trust and collects and distributes  the
income therefrom, the trust is not engaged in business and is not subject
to  the  franchise tax.  Burrell v. Lynch, 274 A.D. 347, 84 N.Y.S.2d  171
(3rd  Dept.  1948), order resettled, 274 A.D. 1083, 85 N.Y.S.2d  705  (3d
Dept. 1949).
     
     In  an Opinion of the Attorney General of the State of New York,  47
N.Y.   Atty.  Gen.  Rep. 213 (Nov. 24, 1942), it was held that where  the
trustee  of  an unincorporated investment trust was without authority  to
reinvest amounts received upon the sales of securities and could  dispose
of  securities  making  up the trust only upon the happening  of  certain
specified  events or the existence of certain specified  conditions,  the
trust was not subject to the franchise tax.
     
     In  the  instant  situation, the Trustee is not  empowered  to  sell
obligations  contained  in  the corpus of  the  Trust  and  reinvest  the
proceeds  therefrom.   Further, the power  to  see  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  Trust  is  liquidated
subsequent to the termination of the Indenture.  Only in circumstances in
which  the  issuer  of  an obligation attempts to refinance  it  can  the
Trustee  exchange  an obligation for a new security.  In  substance,  the
Trustee  will merely collect and distribute income and will not  reinvest
any  income  or  proceeds,  and the Trustee has  no  power  to  vary  the
investment of any Unit holder in the Trust.
     
     Under Subpart E of Part I, Subchapter J of Chapter I of the Internal
Revenue  Code of 1986, as amended (the "Code"), the grantor  of  a  trust
will  be deemed to be the owner of the trust under certain circumstances,
and  therefore  taxable  on  his proportionate  interest  in  the  income
thereof.   Where this Federal tax rule applies, the income attributed  to
the  grantor will also be income to him for New York income tax purposes.
See TSB-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  will   be
considered as owning a share of each asset of the 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 the Trust will be  treated  as  the
income  of each Unit holder in said proportion pursuant to Subpart  E  of
Part I, Subchapter J of Chapter 1 of the Code.
     
     Based  on  the foregoing and on the opinion of Messrs.  Chapman  and
Cutler,   counsel  for  the  Depositor,  dated  today,  upon   which   we
specifically  rely,  we  are  of the opinion that  under  existing  laws,
rulings, and court decisions interpreting the laws of the State and  City
of New York:
     
           1.   The Trust will not constitute an association taxable as a
     corporation  under  New  York law, and,  accordingly,  will  not  be
     subject to tax on its income under the New York State franchise  tax
     or the New York City general corporation tax;
     
           2.   The income of the Trust will be treated as the income  of
     the Unit holders under the income tax laws of the State and City  of
     New York; and
     
           3.    Unit holders who are not residents of the State  of  New
     York  are not subject to the income tax law thereof with respect  to
     any  interest  or gain derived from the Trust or any gain  from  the
     sale  or  other disposition of the Units, except to the extent  that
     such  interest  or  gain is from property employed  in  a  business,
     trade, profession or occupation carried on in the State of New York.
     
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement relating to the Units and to the use of  our  name
and  the reference to our firm in the Registration Statement and  in  the
Prospectus.
                                    
                                    Very truly yours,

     Re:   Van Kampen Merritt Insured Income Trust, Series 50

Dear Mr. Kneedy:
     
     Pursuant  to your request for a Standard & Poor's rating on the units  of
the  above-captioned  trust, SEC #33-62343, we have reviewed  the  information
presented  to us and have assigned a 'AAA' rating to the units of  the  trusts
and  a  'AAA' rating to the securities contained in the trusts for as long  as
they  remain  in  the  trusts.   The ratings are direct  reflections,  of  the
portfolio  of the trusts, 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 trusts.
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 trusts and  to  the  securities
contained in the trust for as long as they remain in the trusts.
     
     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 trusts.   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  trusts.
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,
