Van Kampen American Capital Insured Income Trust,
Series 68 (Intermediate) and Series 69
    

   
The Trusts. Van Kampen American Capital Insured Income Trust, Series 68
(Intermediate) ("Series 68") and Series 69 ("Series 69") are
two separate and distinct unit investment trusts. Series 68 and Series 69 are
collectively referred to herein as the "Trusts". Each Trust initially
consists of delivery statements relating to contracts to purchase debt
obligations and, thereafter, Series 68 will consist of a $3,110,000 aggregate
principal amount portfolio principally comprised of intermediate-term
corporate, taxable municipal or U.S. government debt obligations and Series 69
will consist of a $9,085,000 aggregate principal amount portfolio principally
comprised of long-term corporate, taxable municipal or U.S. government debt
obligations. Series 68 and Series 69 are comprised of 3,110 and 9,085 Units,
respectively.
    

Attention Foreign Investors. If you are not a United States citizen or
resident, your interest income from each Trust may not be subject to Federal
withholding taxes if certain conditions are met. See "Tax Status".

Investment Objective of the Trusts. The investment objective of Series 68 is a
high level of current income consistent with preservation of capital through a
diversified investment in a fixed portfolio principally consisting of
intermediate-term corporate and taxable municipal debt securities issued after
July 18, 1984 (the "Intermediate-term Obligations"). The investment
objective of Series 69 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 "Long-term Obligations").
The Intermediate-term Obligations and the Long-term Obligations are
collectively referred to herein as the "Obligations". See 
"Investment Objectives and Portfolio Selection". There is no assurance that
each 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.

The Trusts and "AAA" Rating. Insurance guaranteeing the payments of
principal and interest, when due, on the Obligations in the portfolio of each
Trust has been obtained from an insurance company either by such 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 14. 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 each 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. 

Units of each 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.

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.

Public Offering Price. The Public Offering Price of the Units of each Trust
during the initial offering period includes the aggregate offering price of
the Obligations in such Trust's portfolio, an applicable sales charge, cash,
if any, in the Principal Account held or owned by such Trust, and accrued
interest, if any. After the initial public offering period, the secondary
market Public Offering Price of each Trust will include the aggregate bid
price of the Obligations in such Trust, and applicable sales charge, cash, if
any, in the Principal Account held or owned by such Trust, and accrued
interest, if any. For sales charges in the secondary market, see "Public
Offering--General". If the Obligations in each 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 each Trust. The minimum purchase
requirement is one Unit except for certain transactions described under 
"Trust Administration--Unit Distribution". See "Public Offering".

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. Record dates for monthly distributions will be the tenth day of each
month and record dates for semi-annual distributions will be the tenth day of
the months indicated under "Per Unit Information" for the applicable
Trust. Distributions will be made on the twenty-fifth day of the month
subsequent to the respective record dates. The first distribution of funds
from the Principal Account of each Trust, if any, will be made on December 25,
1997 to Unitholders of record on December 10, 1997, 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 portfolios of the
respective Trusts plus interest accrued to the date of settlement; however,
during the initial offering period such prices will be based upon the
aggregate offering prices of the 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 of any Van Kampen American Capital-sponsored
unit investment trust may utilize their redemption or termination proceeds to
purchase units of any other Van Kampen American Capital trust in the initial
offering period accepting rollover investments subject to a reduced sales
charge to the extent stated in the related prospectus (which may be deferred
in certain cases). 

Unitholders also have the opportunity to have their distributions reinvested
into an open-end, management investment company as described herein, providing
the potential benefit of compounding. 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 Trusts should be made with an
understanding of the risks associated therewith, including, among other
factors, the inability of the issuer or an insurer to pay the principal of or
interest of a bond when due, volatile interest rates, early call provisions
and general economic conditions. See "Risk Factors".

- ----------
<FN>
<F1> Many unit investment trusts issue a number of units such that each unit
represents approximately $1,000 principal amount of underlying securities. The
Sponsor has elected to follow this format in determining the number of Units
for Series 68. The Sponsor, on the other hand, in determining the number of
Units for Series 69 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.

<F2>Sales charges for the Trusts, expressed as a percentage of the Public Offering
Price per Unit and in parenthesis as a percentage of the aggregate offering
price of the Obligations, are as follows: Series 68--3.0% (3.093%); and Series
69--4.9% (5.152%).

<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
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 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. These rates may not reflect
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 each Trust are set
forth under "Estimated Cash Flows to Unitholders".

THE TRUSTS

- --------------------------------------------------------------------------
Van Kampen American Capital Insured Income Trust, Series 68 (Intermediate) and
Series 69 (the "Trusts") were 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.

Series 68 may be an appropriate medium for investors who desire to participate
in a portfolio of intermediate-term taxable fixed income securities issued
after July 18, 1984 with greater diversification than they might be able to
acquire individually. Series 69 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 each Trust's assets
will not eliminate the risk of loss always inherent in the ownership of
securities. For a breakdown of each portfolio see "Trust Portfolios".
In addition, securities of the type initially deposited in the portfolio of
each 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 "Portfolios" 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 3,110
Units of Series 68 and 9,085 Units of Series 69. Unless otherwise terminated
as provided therein, the Trust Agreement for Series 68 will terminate at the
end of the calendar year prior to the twentieth anniversary of its execution
and the Trust Agreement for Series 69 will terminate at the end of the
calendar year prior to the fiftieth anniversary of its execution. All of the
Obligations in Series 68 are intermediate-term debt instruments with
maturities ranging from 2006 to 2008. All of the Obligations in Series 69 are
long-term debt instruments with maturities ranging from 2017 to 2033. The
dollar weighted average life of the Obligations in each Trust are 10 years and
26 years, respectively.

Each Unit in Series 68 initially offered represents a 1/3,110 undivided
interest in such Trust. Each Unit in Series 69 initially offered represents a
1/9,085 undivided interest in such Trust. To the extent that any Units are
redeemed by the Trustee, the fractional undivided interest in each Trust
represented by each unredeemed Unit will increase, although the actual
interest in each 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 Series 68 is to provide a high level of current
income consistent with safety of principal by investing in a professionally
selected portfolio principally consisting of intermediate-term corporate,
taxable municipal debt or U.S. government obligations issued after July 18,
1984. The investment objective of Series 69 is to provide a high level of
current income consistent with safety of principal by investing in a
professionally selected portfolio principally consisting of long-term
corporate, taxable municipal debt or U.S. government obligations issued after
July 18, 1984.

Insurance guaranteeing the timely payment, when due, of all principal and
interest on the Obligations in each 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) Financial Security Assurance of
Maryland Inc. ("FSA Maryland"), (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 Trusts. 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 each 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 each 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, A Division of the McGraw-Hill Companies.
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 Trusts, 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 PORTFOLIOS 

- --------------------------------------------------------------------------
   
Portfolios. Series 68 (Intermediate) consists of 13 issues, 12 of which have
been issued by municipalities and one of which has been issued by public
utilities. Series 69 consists of 12 issues, 9 of which have been issued by
municipalities and three of which have been issued by public utilities.
Approximately 44% of obligations in Series 68 consist of issues of entities
located in the State of New Jersey.
    

Replacement Obligations. Because certain of the Obligations in the Trusts 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 each 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 each
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) in the case of
Series 68, be intermediate-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, and in the case of Series 69, 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 Trusts to cease to be
rated AAA by Standard & Poor's, A Division of the McGraw-Hill Companies; 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
either 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 Trusts 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 
"Portfolios" for each Trust and footnote (3) in "Notes to
Portfolios".




RISK FACTORS

- --------------------------------------------------------------------------
   
Public Utility Issues. Approximately 16% and 33% of the aggregate principal
amount of the Obligations in Series 68 and Series 69, respectively, are
obligations of public utility issuers. In view of this an investment in the
Trusts 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 portfolios 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 Trusts 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 Trusts 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 84% and 67% of the aggregate principal
amount of the Obligations in Series 68 and Series 69, respectively, may be
taxable obligations of municipal issuers. In view of this an investment in the
Trusts 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 Trusts 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 Trusts may be obligations which are payable
from and secured by revenues derived from the ownership and operation of
facilities such as airports, bridges, turnpikes, port authorities, convention
centers and arenas. In view of this an investment in such a Trust should be
made with an understanding of the characteristics of such issuers and the
risks which such an investment may entail. The major portion of an airport's
gross operating income is generally derived from fees received from signatory
airlines pursuant to use agreements which consist of annual payments for
leases, occupancy of certain terminal space and service fees. Airport
operating income may therefore be affected by the ability of the airlines to
meet their obligations under the use agreements. The air transport industry is
experiencing significant variations in earnings and traffic, due to increased
competition, excess capacity, increased costs, deregulation, traffic
constraints and other factors, and several airlines are experiencing severe
financial difficulties. The Sponsor cannot predict what effect these industry
conditions may have on airport revenues which are dependent for payment on the
financial condition of the airlines and their usage of the particular airport
facility. Similarly, payment on Bonds related to other facilities is dependent
on revenues from the projects, such as user fees from ports, tolls on
turnpikes and bridges and rents from buildings. Therefore, payment may be
adversely affected by reduction in revenues due to such factors as increased
cost of maintenance, decreased use of a facility, lower cost of alternative
modes of transportation, scarcity of fuel and reduction or loss of rents.

Certain of the Obligations in the Trusts may be health care revenue bonds. In
view of this an investment in such a Trust should be made with an
understanding of the characteristics of such issuers and the risks which such
an investment may entail. Ratings of bonds issued for health care facilities
are often based on feasibility studies that contain projections of occupancy
levels, revenues and expenses. A facility's gross receipts and net income
available for debt service may be affected by future events and conditions
including, among other things, demand for services and the ability of the
facility to provide the services required, physicians' confidence in the
facility, management capabilities, competition with other health care
facilities, efforts by insurers and governmental agencies to limit rates,
legislation establishing state rate-setting agencies, expenses, the cost and
possible unavailability of malpractice insurance, the funding of Medicare,
Medicaid and other similar third party payor programs, government regulation
and the termination or restriction of governmental financial assistance,
including that associated with Medicare, Medicaid and other similar third
party payor programs. Pursuant to recent Federal legislation, Medicare
reimbursements are currently calculated on a prospective basis utilizing a
single nationwide schedule of rates. Prior to such legislation Medicare
reimbursements were based on the actual costs incurred by the health facility.
The current legislation may adversely affect reimbursements to hospitals and
other facilities for services provided under the Medicare program. Such
adverse changes also may adversely affect the ratings of Securities held in
the portfolios of the 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. Certain of the Obligations in the Trusts may be "zero
coupon" U.S. Treasury bonds. See footnote (6) in "Notes to
Portfolios". Zero coupon bonds are purchased at a deep discount because
the buyer receives only the right to receive a final payment at the maturity
of the bond and does not receive any periodic interest payments. The effect of
owning deep discount bonds which do not make current interest payments (such
as the zero coupon bonds) is that a fixed yield is earned not only on the
original investment but also, in effect, on all discount earned during the
life of such 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 under the monthly and semi-annual
distribution plans were those indicated in the Summary of Essential Financial
Information" for each 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 Returns 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. These rates may not reflect the true return to
Unitholders which may be lower because of a possible delay in the first
payment to Unitholders.

In order to acquire certain of the Obligations contracted for by the Sponsor
for deposit in the Trusts, 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 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 Trusts, 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 Trusts.

Compensation of Sponsor and Evaluator. The Sponsor will not receive any fees
in connection with its activities relating to the Trusts. However, American
Portfolio Evaluation Services, a division of Van Kampen American Capital
Investment Advisory Corp., which is an affiliate 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 each 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 these Trusts, 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 each 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 each Trust representing semi-annual and monthly distribution
plans. Based on the size of each 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
$1,586 and $4,633 for Series 68 and Series 69, respectively. Assuming in the
alternative that all Unitholders had elected the monthly distribution plan,
such fee would initially amount to $2,830 and $8,267 for Series 68 and Series
69, respectively. The Trustee's fees are payable monthly on or before the
twenty-fifth 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 each
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 $3,100 per annum for Series 69, so long as the Trust retains the
Obligations. Premiums, which are Trust expenses, are payable monthly by the
Trustee on behalf of each Trust. As Obligations in the portfolios 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 Trusts: (a) fees of the Trustee for extraordinary services,
(b) expenses of the Trustee (including legal and auditing expenses) and of
counsel designated by the Sponsor, (c) various governmental charges, (d)
expenses and costs of any action taken by the Trustee to protect the Trusts
and the rights and interests of Unitholders, (e) indemnification of the
Trustee for any loss, liability or expenses incurred by it in the
administration of the Trusts without negligence, bad faith or willful
misconduct on its part, (f) any special custodial fees payable in connection
with the sale of any of the bonds in a Trust, (g) expenditures incurred in
contacting Unitholders upon termination of the Trusts and (h) costs incurred
to reimburse the Trustee for advancing funds to the Trusts to meet scheduled
distributions (which costs may be adjusted periodically in response to
fluctuations in short-term interest rates).

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




INSURANCE ON THE OBLIGATIONS

- --------------------------------------------------------------------------
Insurance has been obtained by each Trust guaranteeing prompt payment of
interest and principal, when due (as more fully described below), in respect
of all the Obligations in the Trusts (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
each 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
"Portfolios"). 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 each 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 a 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 a 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 each 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".

Financial Security Assurance Inc. ("Financial Security" or 
"FSA") is a monoline insurance company incorporated in 1984 under the laws
of the State of New York. Financial Security is licensed to engage in the
financial guaranty insurance business in all 50 states, the District of
Columbia and Puerto Rico.

Financial Security and its subsidiaries are engaged in the business of writing
financial guaranty insurance, principally in respect of securities offered in
domestic and foreign markets. 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 and
its subsidiaries principally insure asset-backed, collateralized and municipal
securities. Asset-backed securities are generally supported by residential
mortgage loans, consumer or trade receivables, securities or other assets
having an ascertainable cash flow or market value. Collateralized securities
include public utility first mortgage bonds and sale/leaseback obligation
bonds. Municipal securities consist largely of general obligation bonds,
special revenue bonds and other special obligations of state and local
governments. Financial Security insures both newly issued securities sold in
the primary market and outstanding securities sold in the secondary market
that satisfy Financial Security's underwriting criteria.

Financial Security is a wholly-owned subsidiary of Financial Security
Assurance Holdings Ltd. ("Holdings"), a New York Stock Exchange listed
company. Major shareholders of Holdings include Fund American Enterprises
Holdings, Inc., U S WEST Capital Corporation and The Tokio Marine and Fire
Insurance Co., Ltd. No shareholder of Financial Security is obligated to pay
any debt of Financial Security or its subsidiaries or any claim under any
insurance policy issued by Financial Security or its subsidiaries or to make
any additional contribution to the capital of Financial Security or its
subsidiaries. As of December 31, 1996, the total policyholders' surplus and
contingency reserves and the total unearned premium reserve, respectively, of
Financial Security and its consolidated subsidiaries were, in accordance with
generally accepted accounting principles, approximately $675,944,000
(unaudited) and $411,732,000 (unaudited), and the total shareholders' equity
and the total unearned premium reserve, respectively, of Financial Security
and its consolidated subsidiaries were, in accordance with generally accepted
accounting principles, approximately $815,332,000 (audited) and $359,972,000
(audited). Copies of Financial Security's financial statements may be obtained
by writing to Financial Security at 350 Park Avenue, New York, New York,
10022, Attention: Communications Department. Its telephone number is (212)
826-0100.

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

The claims-paying ability of Financial Security and FSA Maryland is rated 
"Aaa" by Moody's Investors Service, Inc., and "AAA" by Standard &
Poor's Ratings Services, Nippon Investors Service Inc. and Standard & Poor's
(Australia) Pty. Ltd. Such ratings reflect only the views of the respective
rating agencies, are not recommendations to buy, sell or hold securities and
are subject to revision or withdrawal at any time by such rating agencies.

Capital Guaranty Insurance Company was involved in a merger in 1995. On
December 20, 1995, Capital Guaranty Corporation ("CGC") merged with a
subsidiary of Financial Security Assurance Holdings Ltd. and Capital Guaranty
Insurance Company, CGC's principal operating subsidiary, changed its name to
Financial Security Assurance of Maryland Inc. ("FSA Maryland") and
became a wholly owned subsidiary of Financial Security Assurance Inc. For
further description, see "Financial Security Assurance Inc." herein.

The address of FSA Maryland and its telephone number are Steuart Tower, One
Market Plaza, San Francisco, CA 94105-1413 and (415) 995-8000.

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. Such rating will be in effect for a period of
thirteen months from the Date of Deposit and will, unless renewed, terminate
at the end of such period. See "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 Series 69 portfolio was 6.70% 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's
portfolio was 6.76%. The Estimated Current Return on an identical portfolio
without the insurance obtained by the Trust would have been 6.73% based on the
monthly distribution plan on such date, while the Estimated Long-Term Return
on an identical portfolio without the insurance obtained by the Trust would
have been 6.79%.
    

An objective of portfolio insurance obtained by the Trusts is to obtain a
higher yield on each 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 the
Obligations are debt and 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:

Each 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
a 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 considered to be received by
each 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 a 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 a Trust is
disposed of (whether by sale, exchange, liquidation, redemption, or payment at
maturity) or when the Unitholder redeems or sells his Units. 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. Such basis is determined (before the adjustments
described below) by apportioning the tax basis for the Units among each of the
Trust assets according to value as of the valuation date nearest the date of
acquisition of the Units. 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 to the extent that such
interest accrued on such Obligations before the date the Trust acquired
ownership of the Obligations (and the amount of this reduction may exceed the
amount of accrued interest paid to the sellers) and, consequently, such
Unitholders may have an increase in taxable gain or reduction in capital loss
upon the disposition of such Units. It should be noted that certain
legislative proposals have been made which could effect the calculation of
basis for Unitholders holding securities that are substantially identical to
the Obligations. Unitholders should consult their own tax advisors with regard
to calculation of basis.

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
maturity, redemption or otherwise), gain or loss is recognized to the
Unitholder (subject to various non-recognition provisions of the Code). The
amount of any such gain or loss is measured by comparing the Unitholder's pro
rata share of the total proceeds from such disposition with 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) (or which has market discount) must be increased by the amount
of accrued original issue discount (and market discount, if the Unitholder
elects to include market discount in income as it accrues) and the basis of
each Unit and of each Obligation which was purchased by a 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 basis reduction requirements of the Code relating to amortization of bond
premium may, under some circumstances, result in the Unitholder realizing a
taxable gain when his Units are sold or redeemed for an amount equal to or
less than his original cost. The Treasury Bonds held by a 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 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. 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
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 not
less than a "de minimis" amount as determined under the Regulation. 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. 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 a Trust is deductible by
the Unitholder to the same extent as though the expense had been paid directly
by him. 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 (similar limitations also apply to estates and trusts).
Unitholders may be required to treat some or all of the expenses paid by the
Trusts as miscellaneous itemized deductions subject to this limitation.

Premium. If a Unitholder's tax basis of his pro rata portion in any
Obligations held by a 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 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 premium.

Original Issue Discount. Certain of the Obligations of the Trusts may have
been acquired with "original issue discount." In the case of any
Obligations of a 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 a 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 regarding whether such election should be
made and 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 a 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 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
Trusts 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, subject to various non-recognition provisions of the Code.
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 a Trust
or the disposition of Units by a Unitholder will generally 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 generally will be long-term.
For taxpayers other than corporations, net capital gains (which is defined as
net long-term capital gain over short-term capital loss for a taxable year)
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 basis 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.

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 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. Legislative proposals have been made that would treat certain
transactions designed to reduce or eliminate risk of loss and opportunities
for gain as constructive sales for purposes of recognition of gain (but not
loss). Unitholders should consult their own tax advisors with regard to any
such constructive sales rules.

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) if 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), then 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, or (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 a Trust to such Unitholder including amounts received upon the redemption
of the Units will be subject to back-up withholding.

In the opinion of special counsel to the Trusts for New York tax matters, each
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 Trusts accrue
such interest daily. Because of this, each 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 applicable 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 aggregate offering
price of the Obligations in such Trust's portfolio, a sales charge of 3.0% for
the Public Offering Price (3.093% of the aggregate offering price of the
Obligations) for Series 68 and 4.9% of the Public Offering Price (5.152% of
the aggregate offering price of the Obligations) for Series 69, cash, if any,
in the Principal Account held or owned by such Trust, and accrued interest, if
any. After the initial public offering period, the secondary market public
offering price is based on the bid prices of the Obligations in each Trust, an
applicable sales charge as determined in accordance with the table set forth
below, which is based upon the estimated long-term return life of each Trust,
cash, if any, in the Principal Account held or owned by such Trust, and
accrued interest, if any. 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:

breakpoints above will be adjusted to take into consideration purchase orders  
stated in dollars which cannot be completely fulfilled due to the Trusts'  
requirement that only whole Units be issued.                                  
</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
estimated long-term return life of each 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 are subject to redemption 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 estimated
long-term return life of such Trust's portfolio, in accordance with the
following schedule:

</TABLE>




The sales charges in the above table are expressed as a percentage of the
aggregate bid prices of the Obligations in a Trust. Expressed as a percent of
the Public Offering Price, the sales charge on a Trust consisting entirely of
a portfolio of Obligations with 15 years to maturity would be 4.8%.

Employees, officers and directors (including their spouses, children,
grandchildren, parents, grandparents, siblings, mothers-in-law,
fathers-in-law, sons-in-law and daughters-in-law, and trustees, custodians or
fiduciaries for the benefit of such persons (collectively referred to herein
as "related purchasers")) of Van Kampen American Capital Distributors,
Inc. and its affiliates and Underwriters and their affiliates may purchase
Units at the Public Offering Price less the applicable underwriting commission
or less the applicable dealer concession in the absence of an underwriting
commission and employees, officers and directors (including related
purchasers) of dealers and their affiliates and vendors providing services to
the Sponsor may purchase Units at the Public Offering Price less the
applicable dealer concession.

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 ("immediate family members") will be deemed
for the purposes of calculating the applicable sales charge to be additional
purchases by the purchaser. The reduced sales charges will also be applicable
to a trustee or other fiduciary purchasing securities for one or more trust
estate or fiduciary accounts.

Purchasers of units of any two consecutive series of a Trust may aggregate
purchases of units of such series for purposes of the sales charge reduction
for quantity purchases, provided that at the time of the initial purchase of
units such purchaser submitted a purchase order for at least 100 units that
was partially unfulfilled due to a lack of units of such Trust series
available for sale at such time. The sales charge reduction shall be applied
to the subsequent purchase of units such that the aggregate sales charge
reduction applicable to both purchases will equal the amount described in the
table above.

Units may be purchased in the primary or secondary market at the Public
Offering Price (for purchases which do not qualify for a sales charge
reduction for quantity purchases) less the concession the Sponsor typically
allows to brokers and dealers for purchases (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
each 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 each Trust
was determined by adding to the determination of the aggregate offering price
of the Obligations an amount equal to the applicable sales charge expressed as
a percentage of the aggregate offering price of the Obligations and dividing
the sum so obtained by the number of Units outstanding. This computation
produced a gross underwriting profit equal to such sales charge expressed as a
percentage 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 each Trust prepared by
Interactive Data Corporation, 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 each 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 such Trust is tendered for
redemption, and it shall determine the aggregate value of any Trust as of 4:00
P.M. Eastern time on such other days as may be necessary.

The aggregate price of the Obligations in each 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 Trusts.

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 Trusts 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 each 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 Trusts were higher than the bid side
evaluation of such Obligations by the amount indicated under footnote (5) in
"Notes to Portfolios".

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 (a) for Series 68 of $20.00 per Unit for less than 100 Units, $21.00 per
Unit for any single transaction of 100 to 249 Units, $21.00 per Unit for any
single transaction of 250 to 499 Units, $23.00 per Unit for any single
transaction of 500 to 999 Units and $22.00 per Unit for any single transaction
of 1,000 or more Units, and (b) for Series 69 of $30.00 per Unit for less than
100 Units, $32.00 per Unit for any single transaction of 100 to 249 Units,
$34.00 per Unit for any single transaction of 250 to 499 Units, $35.00 per
Unit for any single transaction of 500 to 999 Units and $34.00 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". Volume concessions or agency commissions of an
additional $2.00 per Unit of Series 68 and $5.00 per Unit of Series 69 will be
given to any broker/dealer or agent (other than Underwriters) who purchases
from the Sponsor at least 250 Units of such Trust during the initial offering
period. The breakpoint concessions or agency commissions listed above are also
applied on a dollar basis utilizing a breakpoint equivalent of $1,000 per Unit
and will be applied on whichever basis is more favorable to the distributor.
The breakpoints above will be adjusted to take into consideration purchase
orders stated in dollars which cannot be completely fulfilled due to the
Trusts' requirement that only whole Units be issued. Certain commercial banks
are making Units of the Trusts 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 Trusts; 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 for each trust as set forth above.

Except as stated hereinafter, the minimum purchase requirement in the initial
offering period and in the secondary market is one Unit. In connection with
fully disclosed transactions with the Sponsor, the minimum purchase
requirement will be that number of Units set forth in the contract between the
Sponsor and the related broker or agent.

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
that percentage of the Public Offering Price of the Units as indicated under
"Offering Price", 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 $22.00 and $35.00 per Unit of Series 68 and Series 69,
respectively, as of the Date of Deposit. In connection with quantity sales to
purchasers of Series 68 the Underwriters will receive from the Sponsor
commissions totalling $23.00 per Unit for any single transaction of 100 to 249
Units, $23.00 per Unit for any single transaction of 250 to 499 Units, $25.00
per Unit for any single transaction of 500 to 999 Units and $24.00 per Unit
for any single transaction of 1,000 or more Units. In connection with quantity
sales to purchasers of Series 69 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 it underwrites. All breakpoints listed above
are also applied on a dollar basis utilizing a breakpoint equivalent of $1,000
per Unit and will be applied on whichever basis is more favorable to the
Underwriter. The breakpoints will be adjusted to take into consideration
purchase orders stated in dollars which cannot be completely fulfilled due to
the Trusts' requirement that only whole Units be issued. 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
each 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 Corporation). 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 either 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
each Trust after the Date of Deposit, since all proceeds received from
purchasers of Units (excluding dealer concessions or agency commissions
allowed, if any) will be retained by the Underwriters. Affiliates of an
Underwriter are entitled to the same dealer concessions or agency 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 Trusts. 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 each 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 each
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 of each Trust 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 of such Trust plus any accrued interest. The aggregate bid prices of
the underlying Obligations in a 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 unless a Unitholder makes
a request to the Trustee that Units be held in book-entry form. 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 (or on such request) 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 a Trust,
including that part of the proceeds of any disposition of Obligations which
represents accrued interest and including 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 a 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 twenty-fifth day of each month on a pro rata basis to Unitholders of
record as of the preceding record date (which will be the tenth day of the
month) who are entitled to distributions at that time under the plan of
distribution chosen. 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 twenty-fifth 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 of a Trust as of each record date after
the First Settlement Date will be made on the following distribution date or
shortly thereafter and shall consist of an amount substantially equal to such
portion of the Unitholders' pro rata share of the estimated net annual
interest income in the Interest Account of such Trust after deducting
estimated expenses attributable as is consistent with the distribution plan
chosen. Because interest payments are not received by a Trust at a constant
rate throughout the year, such interest distribution may be more or less than
the amount credited to such Interest Account as of the record date. For the
purpose of minimizing fluctuation in the distributions from an Interest
Account, the Trustee is authorized to advance such amounts as may be necessary
to provide interest distributions of approximately equal amounts. The Trustee
shall be reimbursed for any such advances from funds in the 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 tenth 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 each 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 may elect to have each distribution of
interest income, capital gains and/or principal on their Units automatically
reinvested in shares of any Van Kampen American Capital mutual funds (except
for B shares) which are registered in the Unitholder's state of residence.
Such mutual funds are hereinafter collectively referred to as the "
Reinvestment Funds." By reinvesting distributions, investors have the
power to increase earning potential by compounding. If Trust distributions are
reinvested into another investment, the return would be higher than if
distributions were merely taken out of the investment as a source of income.

 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. Unitholders with an existing Guaranteed Reinvestment
Option (GRO) Program account (whereby a sales charge is imposed on
distribution reinvestments) may transfer their existing account into a new GRO
account which allows purchases of Reinvestment Fund shares at net asset value
as described above. 

Confirmations of all reinvestments by a Unitholder into a Reinvestment Fund
will be mailed to the Unitholder by such Reinvestment Fund. A participant may
at any time prior to five days preceding the next succeeding distribution
date, by so notifying the Trustee in writing, elect to terminate his or her
reinvestment plan and receive future distributions 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 of a Trust 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), if any, being distributed expressed in each case as a dollar
amount representing the pro rata share of each Unit of a Trust outstanding.
For as long as the Trustee deems it to be in the best interests of the
Unitholders, the accounts of each Trust shall be audited, not less frequently
than annually, by independent certified public accountants and the report of
such accountants shall be furnished by the Trustee to Unitholders upon
request. Within a reasonable period of time after the end of each calendar
year, the Trustee shall furnish to each person who at any time during the
calendar year was a registered Unitholder of a Trust a statement (i) as to the
Interest Account: interest received (including amounts representing interest
received upon any disposition of 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 a Trust furnished to it by the Evaluator.

Each distribution statement of a Trust will reflect pertinent information in
respect of the other plan of distribution so that Unitholders may be informed
regarding the results of such other plan of distribution.

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 (or by written request if Units are not held in
certificated form), 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 of such Trust or, if the balance therein is insufficient, from the
Principal Account of such Trust. All other amounts will be withdrawn from the
Principal Account of such Trust. The Trustee is empowered to sell underlying
Obligations of a Trust in order to make funds available for redemption. Units
so redeemed shall be cancelled.

The Redemption Price per Unit (as well as the secondary market Public Offering
Price) will be determined on the basis of the bid price of the Obligations in
each Trust, while the initial and primary Public Offering Price of Units will
be determined on the basis of the offering price of the 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 in each Trust and includes the sales charge) exceeded the value at
which Units could have been redeemed (based upon the current bid prices of the
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 each
Trust by employing any of the methods set forth in "Public
Offering--Offering Price". In determining the Redemption Price per Unit no
value will be assigned to the portfolio insurance maintained 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 Trusts, 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 twentieth anniversary of the Trust Agreement in the case of Series 68 or
beyond the end of the year preceding the fiftieth anniversary of the Trust
Agreement in the case of Series 69. In the event of termination of either
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 gross negligence (negligence in the case of the Trustee) in the
performance of their duties or by reason of their reckless disregard of their
obligations and duties hereunder. The Trustee shall not be liable for
depreciation or loss incurred by reason of the sale by the Trustee of any of
the Obligations. In the event of the failure of the Sponsor to act under the
Trust Agreement, the Trustee may act thereunder and shall not be liable for
any action taken by it in good faith under the Trust Agreement.

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

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

   
Sponsor. Van Kampen American Capital Distributors, Inc., a Delaware
corporation, is the Sponsor of the Trust. The Sponsor is an indirect
subsidiary of VK/AC Holding, Inc. VK/AC Holding, Inc. is a wholly owned
subsidiary of MSAM Holdings II, Inc., which in turn is a wholly owned
subsidiary of Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD").

MSDWD is a global financial services firm with a market capitalization of more
than $21 billion which was created by the merger of Morgan Stanley Group Inc.
with and into Dean Witter, Discover & Co. on May 31, 1997. MSDWD, together
with various of its directly and indirectly owned subsidiaries, is engaged in
a wide range of financial services through three primary businesses:
securities, asset management and credit services. These principal businesses
include securities underwriting, distribution and trading; merger,
acquisition, restructuring and other corporate finance advisory activities;
merchant banking; stock brokerage and research services; asset management;
trading of futures, options, foreign exchange commodities and swaps (involving
foreign exchange, commodities, indices and interest rates); real estate
advice, financing and investing; global custody, securities clearance services
and securities lending; and credit card services. As of June 2, 1997, MSDWD,
together with its affiliated investment advisory companies, had approximately
$270 billion of assets under management, supervision or fiduciary advice.

Van Kampen American Capital Distributors, Inc. specializes in the underwriting
and distribution of unit investment trusts and mutual funds with roots in
money management dating back to 1926. The Sponsor is a member of the National
Association of Securities Dealers, Inc. and has offices at One Parkview Plaza,
Oakbrook Terrace, Illinois 60181, (630) 684-6000 and 2800 Post Oak Boulevard,

Philadelphia and has regional representatives in Atlanta, Dallas, Los Angeles,
New York, San Francisco, Seattle and Tampa. As of November 30, 1996 the total
stockholders' equity of Van Kampen American Capital Distributors, Inc. was
$129,451,000 (unaudited). (This paragraph relates only to the Sponsor and not
to the Trusts or to any other Series thereof. The information is included
herein only for the purpose of informing investors as to the financial
responsibility of the Sponsor and its ability to carry out its contractual
obligations. More detailed financial information will be made available by the
Sponsor upon request.)

As of March 31, 1997, the Sponsor and its Van Kampen American Capital
affiliates managed or supervised approximately $58.45 billion of investment
products, of which over $10.85 billion is invested in municipal securities.
The Sponsor and its Van Kampen American Capital affiliates managed $47 billion
of assets, consisting of $29.23 billion for 59 open-end mutual funds (of which
46 are distributed by Van Kampen American Capital Distributors, Inc.) $13.4
billion for 37 closed-end funds and $4.97 billion for 106 institutional
accounts. The Sponsor has also deposited approximately $26 billion of unit
investment trusts. All of Van Kampen American Capital's open-end funds,
closed-ended funds and unit investment trusts are professionally distributed
by leading financial firms nationwide. Based on cumulative assets deposited,
the Sponsor believes that it is the largest sponsor of insured municipal unit
investment trusts, primarily through the success of its Insured Municipals
Income Trust(R)or the IM-IT(R)trust. The Sponsor also provides
surveillance and evaluation services at cost for approximately $13 billion of
unit investment trust assets outstanding. Since 1976, the Sponsor has serviced
over two million investor accounts, opened through retail distribution firms.

If the Sponsor shall fail to perform any of its duties under the Trust
Agreement or become incapable of acting or shall 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 Trusts 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 portfolios of either of
the Trusts.

In accordance with the Trust Agreement, the Trustee shall keep proper books of
record and account of all transactions at its office for each Trust. Such
records shall include the name and address of, and the certificates issued by
each Trust to, every Unitholder of the Trusts. 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 each Trust.

Under the Trust Agreement, the Trustee or any successor trustee may resign and
be discharged of the Trusts created by the Trust Agreement by executing an
instrument in writing and filing the same with the Sponsor. The Trustee or
successor trustee must mail a copy of the notice of resignation to all
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 Trusts, 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 each 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.

Trustee and as special counsel for the Trust for New York tax matters.
    

Independent Certified Public Accountants. The statements of condition and the

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 68 (Intermediate) and Series 69:

We have audited the accompanying statements of condition and the related
portfolios of Van Kampen American Capital Insured Income Trust, Series 68
(Intermediate) and Series 69 as of July 10, 1997. The statements of condition
and portfolios are the responsibility of the Sponsor. Our responsibility is to
express an opinion on such financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of 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 68 (Intermediate) and Series 69 as of July 10,
1997, in conformity with generally accepted accounting principles.

<F1>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 each Trust has been obtained
by each Trust except for Obligations in each 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 Trusts is effective only while the Obligations are
held in such Trusts, 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 Trusts.

<F2>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. 

<F3>The Trustee will advance to each Trust the amount of net interest accrued to
July 15, 1997, 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. See
"Insurance on the Obligations".

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



   
NOTES TO PORTFOLIOS:
As of the Date of Deposit: July 10, 1997

- --------------------------------------------------------------------------
(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 July
7, 1997 to July 10, 1997. These Obligations have expected settlement dates
from July 11, 1997 to July 17, 1997 (see "Trust Portfolios").
    

(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 accredited 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 Portfolios--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 each 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 portfolios. 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
Trusts were higher than the bid side evaluation of such Obligations by 0.38%
and 0.50% of the aggregate principal amount of such Obligations for Series 68
and Series 69, respectively. 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% and 4% of the aggregate
principal amount of the Obligations in Series 68 and Series 69, respectively,
are "zero coupon" bonds.
    

(7)Standard & Poor's has assigned its "AAA" investment rating to all
of the Obligations while in the Trusts, 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.

1.   Definitions

    (a)   "Policy" is this policy of insurance and all applications and
schedules for Municipal Bond Investment Trust Insurance relating hereto,
all of which are hereby incorporated by reference herein.

    (b)   "Bonds" are the specific securities covered by this Policy and
are identified and described in the Schedule attached hereto and hereby
made a part hereof.

    (c)   "Issuer" is each respective issuer, identified in the Schedule,
of the Bonds.

    (d)   "Investment Trust" is the entity represented to have an
insurable interest in the Bonds insured under this Policy, identified on
the face of this Policy.

    (e)   "Trustee" is the Trustee of the Investment Trust, or any
successor Trustee thereto or Co-Trustee therewith.

    (f)   "Sponsor" is the firm or entity responsible for creating the
Investment Trust and thereafter performing the services to it required of
its sponsor, or any successor Sponsor thereof or Co-Sponsor therewith.

    (g)   "Insured Instrument" is any instrument evidencing all or any
part of the principal or of interest on a Bond which is Due for Payment.

    (h)   "Policy Period" is the period during which this Policy of
insurance is effective.  The Policy Period commences at 12:01 A.M.

    (i)    "Premium Installment Period" is the period for  which
installments of the annual insurance premium are payable monthly,
quarterly or semiannually, as determined initially for the Investment
Trust.

    (j)   "Nonpayment" is the failure of an Issuer to provide sufficient
funds to the payment agent for payment in full of all principal and
interest on a Bond which is Due for Payment.

    (k)   "Due for Payment," when referring to principal of a Bond (or
Insured Instrument evidencing such principal), is when the stated
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
other advancement of maturity; and when referring to interest on a Bond
(or Insured Instrument evidencing such interest), is when the stated date
for payment has been reached.

    (l)   "Bond Proceedings" are the legal proceedings by which each of
the Bonds has been authorized, issued or secured, including the governing
statutes, the pertinent resolutions and ordinances of the Issuer, and any
trust indenture, mortgage, lease agreement or other contract relating to
the Bond or its security.


2.   Noncancellability and Termination-Refunds of Premium
     
     This Policy cannot be cancelled by AMBAC.  The insurance provided by
this Policy shall remain in force throughout the Policy period.  This
Policy provides for payment to the Trustee as a result of Nonpayment of
the Bonds.  In the event the Trustee sells any of the Bonds, then this
Policy shall be terminated as to any such Bond on the date of said sale,
and AMBAC shall not have any liability under t his Policy on account of
Nonpayment of any such Bond occurring thereafter.  This Policy shall be
terminated as to any Bond which AMBAC has been notified by the Sponsor or
by the Trustee has been redeemed from or sold by the Investment Trust, or
was not deposited by the Sponsor, or the contract to purchase which has
failed, on the date such notice is received by AMBAC, and AMBAC shall not
have any liability under this Policy on account of Nonpayment of any such
Bond occurring thereafter.  When AMBAC is notified by the Trustee or the
Sponsor that any of the Bonds have been redeemed or sold from the
Investment Trust, or were not deposited into it, or a contract to
purchase any such Bonds has failed, a refund of any prepaid premium
thereof shall be made to the Investment Trust or the Sponsor, as the case
may be.  Such notification to AMBAC must specify the amount of Bonds
affected, identify each by its Item Number in an Application identified
by its date and designate the date of such disposal or failure.


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

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

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

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


4.   Rights of AMBAC

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

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

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

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


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


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


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


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


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

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

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

Gentlemen:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     Re:   Van Kampen American Capital Insured Income Trust,
                        Series 68 and Series 69

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 68 and Series 69 (the  "Fund"),  in
connection  with  the  preparation, execution and  delivery  of  a  Trust
Agreement  dated  July  10,  1997, 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.  333-30739)  relating  to  the  Units
referred to above and to the use of our name and to the reference to  our
firm in said Registration Statement and in the related Prospectus.

                                    Respectfully submitted,

     Re:   Van Kampen American Capital Insured Income Trust,
                        Series 68 and Series 69

Gentlemen:
     
     We   have   acted  as  counsel  for  Van  Kampen  American   Capital
Distributors,  Inc.,  Depositor of Van Kampen  American  Capital  Insured
Income Trust, Series 68 and Series 69 (the "Trusts"), in connection  with
the  issuance  of Units of fractional undivided interest  in  the  Trust,
under  a Trust Agreement dated July 10, 1997 (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 Trusts will consist of a portfolio of intermediate-
term  and 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 the Obligations are debt and that interest on  each
of  the  Obligations (including the Taxable Municipal Bonds, if any)  are
includable in gross income for federal income tax purposes.
     
     Based  upon the foregoing and upon an investigation of such  matters
of law as we consider to be applicable, we are of the opinion that, under
existing Federal income tax law:
     
          (i)   Each Trust is not an association taxable as a corporation
     for  Federal  income  tax  purposes but  will  be  governed  by  the
     provisions  of  Subpart  E, subchapter J  (relating  to  trusts)  of
     chapter 1, Internal Revenue Code of 1986 (the "Code").
     
         (ii)    Each Unitholder will be considered as owning a pro  rata
     share  of  each  asset of a Trust for Federal income  tax  purposes.
     Under subpart E, subchapter J of chapter 1 of the Code, income of  a
     Trust will be treated as income of each Unitholder.  Each Unitholder
     will  be  considered to have received his pro rata share  of  income
     derived from each Trust asset when such income is considered  to  be
     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  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 rules 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,  generally
     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  valuation date closest  to  the  date  the
     Unitholder purchases his Units), in order to determine his tax basis
     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)    Each  Unitholder  will have  a  taxable  event  when  an
     Obligation  of  a  Trust is disposed of (whether by sale,  exchange,
     liquidation,  redemption,  or  payment  at  maturity)  or  when  the
     Unitholder redeems or sells his Units.  A Unitholder's tax basis  in
     his Unit will equal his tax basis in his pro rata portion of all  of
     the  assets  of  the  Trust.  Such basis is determined  (before  the
     adjustments described below) by apportioning the tax basis  for  the
     Units  among each of the Trust assets according to value as  of  the
     valuation  date  nearest  the  date of  acquisition  of  the  Units.
     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 to the extent that such
     interest  accrued  on such Obligations before  the  date  the  Trust
     acquired  ownership  of  the Obligations (and  the  amount  of  this
     reduction  may  exceed the amount of accrued interest  paid  to  the
     sellers) 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   maturity,
     redemption  or  otherwise),  gain  or  loss  is  recognized  to  the
     Unitholder  (subject to various non-recognition  provisions  of  the
     Code).  The amount of any such gain or loss is measured by comparing
     the  Unitholder's  pro rata share of the total  proceeds  from  such
     disposition with 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)  (or  which  has market discount) must be  increased  by  the
     amount  of accrued original issue discount (and market discount,  if
     the  Unitholder elects to include market discount in  income  as  it
     accrues) and the basis of each Unit and of each Obligation which was
     purchased  by  a 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  basis
     reduction requirements of the Code relating to amortization of  bond
     premium  may,  under some circumstances, result  in  the  Unitholder
     realizing a taxable gain when his Units are sold or redeemed for  an
     amount equal to or less than his original cost.
     
     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.  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  (similar
limitations  also  apply  to  estates and trusts).   Unitholders  may  be
required  to  treat  some  or  all  of  the  expenses  of  the  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 over the term of the Obligations.  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.   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 pro rata portion of 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), 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  for  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  was  not
currently  deductible  would ultimately be deductible  when  the  accrued
market discount is included in income.
     
     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  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.
     
     A  Unitholder will recognize taxable gain (or loss) when all or part
of  the  pro rata interest in an Obligation is disposed of for an  amount
greater  (or  less) than his tax basis therefor in a taxable transaction,
subject to various non-recognition provisions of the Code.
     
     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 basis 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.
     
     "The Revenue Reconciliation Act of 1993" (the "Tax Act") raised  tax
rates  on  ordinary income while capital gains remain  subject  to  a  28
percent  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 recharacterizes
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.
     
     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 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)   if 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.
     
     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."   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  foreign,  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, Intermediate Series 68 and Series 69
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 68, Intermediate and Van  Kampen  American
Capital Insured Income Trust, Series 69 (individually the "Trust" and  in
the aggregate the "Trusts" or the "Fund") for purposes of determining the
applicability   of  certain  New  York  taxes  under  the   circumstances
hereinafter described.
     
     The Fund is created pursuant to a Trust Agreement (the "Indenture"),
dated  as  of  today  (the "Date of Deposit") among Van  Kampen  American
Capital   Distributors,  Inc.  (the  "Depositor"),   American   Portfolio
Evaluation Services, a division of Van Kampen American Capital Investment
Advisory Corp., an affiliate of the Depositor, as Evaluator, and The Bank
of  New  York as trustee (the "Trustee").  As described in the prospectus
relating  to  the  Fund  dated today to be filed as  an  amendment  to  a
registration statement heretofore filed with the Securities and  Exchange
Commission (file number 333-30739) under the Securities Act of  1933,  as
amended   (the  "Prospectus"  and  the  "Registration  Statement"),   the
objectives  of  the Fund 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 long-term corporate  debt
securities.  It is noted that no opinion is expressed herein with  regard
to the Federal tax aspects of the bonds, the Fund, units of the Fund (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
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 will provide, that the amount paid by the insurer  in
respect  of any bond may not exceed the amount of principal and  interest
due on the bond and such payment will in no event relieve the issuer from
its continuing obligation to pay such defaulted principal and interest in
accordance with the terms of the obligation.
     
     The Trustee will not participate in the selection of the obligations
to  be  deposited  in  the Trusts, and, upon the  receipt  thereof,  will
deliver to the Depositor registered certificates for the number of  Units
representing  the entire capital of the Fund 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  Fund  and with the proceeds from  the  disposition  of
obligations  held in the Fund 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
Fund  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 Fund may be removed therefrom  by
the  Trustee only upon redemption prior to their stated maturity, at  the
direction of the Depositor in the event of an advance refunding  or  upon
the  occurrence of certain other specified events which adversely  affect
the sound investment character of the Fund, such as default by the issuer
in  payment of interest or principal on the 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 a Fund, 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 funds are
not  available.   The  Trustee  does not  have  the  power  to  vary  the
investment  of any Unit holder in a Fund, and under no circumstances  may
the  proceeds  of  sale of any obligations held by the Fund  be  used  to
purchase new obligations to be held therein.
     
     Article  9-A  of  the New York Tax Law imposes a  franchise  tax  on
business corporations, and, for purposes of that Article, Section  208(l)
defines  the  term  "corporation" to include, among  other  things,  "any
business conducted by a trustee or trustees wherein interest or ownership
is evidenced by certificate or other written instrument."
     
     The Regulations promulgated under Section 208 provide as follows:
     
     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 funds and the collection of  income
therefrom, with incidental replacement of securities and reinvestment  of
funds,  does not constitute the conduct of a business in the  case  of  a
business  conducted by a trustee or trustees. 20 NYCRR 1-2.3(b)(2)  (July
11, 1990).
     
     New York cases dealing with the question of whether a trust will  be
subject  to the franchise tax have also delineated the general rule  that
where  a  trustee  merely invests funds and collects and distributes  the
income therefrom, the trust is not engaged in business and is not subject
to  the  franchise tax.  Burrell v. Lynch, 274 A.D. 347, 84 N.Y.S.2d  171
(3rd  Dept.  1948), order resettled, 274 A.D. 1083, 85 N.Y.S.2d  705  (3d
Dept. 1949).
     
     In  an Opinion of the Attorney General of the State of New York,  47
N.Y.  Att'y.  Gen. Rep. 213 (Nov. 24, 1942), it was held that  where  the
trustee  of  an unincorporated investment trust was without authority  to
reinvest amounts received upon the sales of securities and could  dispose
of  securities  making  up the trust only upon the happening  of  certain
specified  events or the existence of certain specified  conditions,  the
trust was not subject to the franchise tax.
     
     In  the  instant situation, the Trustee is not empowered to  and  we
assume will not, sell obligations contained in the corpus of the Fund and
reinvest  the  proceeds  therefrom.  Further,  the  power  to  sell  such
obligations is limited to circumstances in which the creditworthiness  or
soundness of the obligation is in question or in which cash is needed  to
pay  redeeming  Unit holders or to pay expenses, or  where  the  Fund  is
liquidated  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 Fund.
     
     Under Subpart E of Part I, Subchapter J of Chapter 1 of the Internal
Revenue  Code of 1986, as amended (the "Code"), the grantor  of  a  trust
will  be deemed to be the owner of the trust under certain circumstances,
and  therefore  taxable  on  his proportionate  interest  in  the  income
thereof.   Where this Federal tax rule applies, the income attributed  to
the  grantor will also be income to him for New York income tax purposes.
See TSB-M-78(9)(c), New York Department of Taxation and Finance, June 23,
1978.
     
     By  letter, dated today, Messrs. Chapman and Cutler, counsel for the
Depositor,  rendered  their  opinion  that  each  Unit  holder  will   be
considered  as owning a share of each asset of the Fund 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 Fund 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 Fund 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 Fund 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 Fund or any gain from the sale
     or  other  disposition of the Units, except to the extent that  such
     interest  or  gain  is from property employed in a business,  trade,
     profession or occupation carried on in the State of New York.
     
     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 American Capital Insured Income Trust,
                  Intermediate Series 68 and Series 69

Dear Mr. Kneedy:
     
     Pursuant  to your request for a Standard & Poor's rating on the units  of
the  above-captioned trust, SEC #333-30739, 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.
     
     Standard  &  Poor's will maintain surveillance on the "AAA" rating  until
August 10, 1998.  On this date, the rating will be automatically withdrawn  by
Standard & Poor's unless a post effective letter is requested by the Trust.
     
     You  have permission to use the name of Standard & Poor's Corporation and
the   above-assigned  ratings  in  connection  with  your   dissemination   of
information relating to these units, provided that it is understood  that  the
ratings are not "market" ratings nor recommendations to buy, hold, or sell the
units  of  the trust or the securities contained in the 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,
