VAN KAMPEN MERRITT INSURED INCOME TRUST, INTERMEDIATE SERIES 33
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1998, 1999 AND 2000
--------------------------------------------------------------------------------

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Obligation Valuation - Obligations are stated at the value determined by the
Evaluator, American Portfolio Evaluation Services (a division of an affiliate of
the Sponsor). The Evaluator may determine the value of the Obligations (1) on
the basis of current bid prices of the Obligations obtained from dealers or
brokers who customarily deal in Obligations comparable to those held by each of
the Trusts, (2) on the basis of bid prices for comparable Obligations, (3) by
determining the value of the Obligations by appraisal or (4) by any combination
of the above. The Trust maintains insurance which provides for the timely
payment when due, of all principal and interest on Obligations owned by it.
Except in cases in which Obligations are in default, or significant risk of
default, the valuation does not include any value attributable to this insurance
feature since the insurance terminates as to any Obligation at the time of its
disposition.

Obligation Cost - The original cost to the Trust was based on the
determination by Interactive Data Corporation of the offering prices of the
Obligations on the date of deposit (November 30,1993). Since the valuation is
based upon the bid prices, the Trust recognized a downward adjustment of $23,118
on the date of deposit resulting from the difference between the bid and
offering prices. This downward adjustment was included in the aggregate amount
of unrealized depreciation reported in the financial statements for the period
ended July 31, 1994.

Federal Income Taxes - The Trust is not a taxable entity for Federal income
tax purposes. Each Unitholder is considered to be the owner of a pro rata
portion of such Trust and, accordingly, no provision has been made for Federal
income taxes.

Other - The financial statements are presented on the accrual basis of
accounting. Any realized gains or losses from securities transactions are
reported on an identified cost basis.

NOTE 2 - PORTFOLIO
Ratings - The source of all ratings, exclusive of those designated N/R or *
is Standard & Poor's, A Division of the McGraw-Hill Companies. Ratings marked *
are by Moody's Investors Service, Inc. as these Obligations are not rated by
Standard & Poor's, A Division of the McGraw-Hill Companies. N/R indicates that
the Obligation is not rated by Standard & Poor's, A Division of the McGraw-Hill
Companies or Moody's Investors Service, Inc. The ratings shown represent the
latest published ratings of the Obligations. For a brief description of rating
symbols and their related meanings, see "Description of Securities Ratings" in
the Information Supplement.

Redemption Feature - There is shown under this heading the year in which each
issue of Obligations is initially or currently callable and the call price for
that year. Each issue of Obligations continues to be callable at declining
prices thereafter (but not below par value) except for original issue discount
Obligations which are redeemable at prices based on the issue price plus the
amount of original issue discount accreted to redemption date plus, if
applicable, some premium, the amount of which will decline in subsequent years.
"S.F." indicates a sinking fund is established with respect to an issue of
Obligations. "P.R." indicates an Obligation has been prerefunded. Redemption
pursuant to call provisions generally will, and redemption pursuant to sinking
fund provisions may, occur at times when the redeemed Obligations have an
offering side evaluation which represents a premium over par. 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 in excess of $1 per Unit semi-annually and any premium received on such
redemption. However, should the amount available for distribution in the
Principal Account 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
Estimated Current Return in this event may be affected by such redemptions. For
the Federal tax effect on Unitholders of such redemptions and resultant
distributions, see "Federal Tax Status" in Part II.

NOTE 2 - PORTFOLIO (CONTINUED)
Insurance - Insurance coverage providing for the timely payment when due of
all principal and interest on the Obligations in the Trust has been obtained by
the Trust or by one of the Preinsured Obligations Insurers (as indicated in the
Obligation name). Such insurance does not guarantee the market value of the
Obligations or the value of the Units. For Obligations covered under the Trust's
insurance policy the insurance is effective only while Obligations thus insured
are held in the Trust and the insurance premium, which is a Trust obligation, is
paid on a monthly basis. The premium for insurance which has been obtained from
various insurance companies by the issuer of the Obligation involved is payable
by the issuer. Insurance expense for the period reflects adjustments for
redeemed or sold Obligations.

An Accounting and Auditing Guide issued by the American Institute of
Certified Public Accountants states that, for financial reporting purposes,
insurance coverage of the type acquired by the Trust does not have any
measurable value in the absence of default of the underlying Obligations or
indication of the probability of such default. In the opinion of the Evaluator,
there is no indication of a probable default of Obligations in the portfolio as
of the date of these financial statements.

Unrealized Appreciation and Depreciation - An analysis of net unrealized
appreciation (depreciation) at July 31, 2000 is as follows:

Unrealized Appreciation $ --
Unrealized Depreciation (123,509)
--------------
$ (123,509)
==============

NOTE 3 - OTHER
Marketability - Although it is not obligated to do so, the Sponsor intends to
maintain a market for Units and to continuously offer to purchase Units at
prices, subject to change at any time, based upon the aggregate bid price of the
Obligations in the portfolio of the Trust, plus interest accrued to the date of
settlement. If the supply of Units exceeds demand, or for other business
reasons, the Sponsor may discontinue purchases of Units at such prices. In the
event that a market is not maintained for the Units, a Unitholder desiring to
dispose of his Units may be able to do so only by tendering such Units to the
Trustee for redemption at the redemption price.

Cost to Investors - The cost to original investors was based on the
Evaluator's determination of the aggregate offering price of the Obligations per
Unit on the date of an investor's purchase, plus a sales charge of 3.0% of the
public offering price which is equivalent to 3.093% of the aggregate offering
price of the Obligations. The secondary market cost to investors is based on the
Evaluator's determination of the aggregate bid price of the Obligations per Unit
on the date of an investor's purchase plus a sales charge based upon the years
to average maturity of the Obligations in the portfolio. The sales charge ranges
from 1.0% of the public offering price (1.010% of the aggregate bid price of the
Obligations) for a Trust with a portfolio with less than two years to average
maturity to 5.40% of the public offering price (5.708% of the aggregate bid
price of the Obligations) for a Trust with a portfolio with twenty-one or more
years to average maturity.

Compensation of Evaluator - The Evaluator receives a fee for providing
portfolio supervisory services for the Trust ($.25 per Unit, not to exceed the
aggregate cost of the Evaluator for providing such services to all applicable
Trusts). In addition, the Evaluator receives an annual fee for regularly
evaluating the Trust's portfolio. Both fees may be adjusted for increases under
the category "All Services Less Rent of Shelter" in the Consumer Price Index.

NOTE 4 - REDEMPTION OF UNITS
During the three years ended July 31, 1998, 1999 and 2000, 476 Units, 353
Units and 383 Units, respectively, were presented for redemption.

VAN KAMPEN MERRITT INSURED INCOME TRUST, SERIES 34
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1998, 1999 AND 2000
-------------------------------------------------------------------------------

Obligation Cost - The original cost to the Trust was based on the
determination by Interactive Data Corporation of the offering prices of the
Obligations on the date of deposit (November 30, 1993). Since the valuation is
based upon the bid prices, the Trust recognized a downward adjustment of $50,125
on the date of deposit resulting from the difference between the bid and
offering prices. This downward adjustment was included in the aggregate amount
of unrealized depreciation reported in the financial statements for the period
ended July 31, 1994.

Unit Valuation - The redemption price per Unit is the pro rata share of each
Unit based upon (1) the cash on hand in such Trust or monies in the process of
being collected, (2) the Obligations in the Trust based on the value determined
by the Evaluator and (3) interest accrued thereon, less accrued expenses of the
Trust, if any.
Federal Income Taxes - The Trust is not a taxable entity for Federal income
tax purposes. Each Unitholder is considered to be the owner of a pro rata
portion of such Trust and, accordingly, no provision has been made for Federal
income taxes.

Other - The financial statements are presented on the accrual basis of
accounting. Any realized gains or losses from securities transactions are
reported on an identified cost basis.

Unrealized Appreciation and Depreciation - An analysis of net unrealized
appreciation (depreciation) at July 31, 2000 is as follows:

Unrealized Appreciation $ 85,092
Unrealized Depreciation (565,316)
--------------
$ (480,224)
==============

Cost to Investors - The cost to original investors was based on the
Evaluator's determination of the aggregate offering price of the Obligations per
Unit on the date of an investor's purchase, plus a sales charge of 4.9% of the
public offering price which is equivalent to 5.152% of the aggregate offering
price of the Obligations. The secondary market cost to investors is based on the
Evaluator's determination of the aggregate bid price of the Obligations per Unit
on the date of an investor's purchase plus a sales charge based upon the years
to average maturity of the Obligations in the portfolio. The sales charge ranges
from 1.0% of the public offering price (1.010% of the aggregate bid price of the
Obligations) for a Trust with a portfolio with less than two years to average
maturity to 5.40% of the public offering price (5.708% of the aggregate bid
price of the Obligations) for a Trust with a portfolio with twenty-one or more
years to average maturity.

NOTE 4 - REDEMPTION OF UNITS
During the three years ended July 31, 1998, 1999 and 2000, 277 Units, 1,161
Units and 1,068 Units, respectively, were presented for redemption.

PROSPECTUS PART II

SEPTEMBER 2000

INSURED INCOME TRUST

This prospectus contains two parts.

No one may use this Prospectus Part II unless accompanied by Prospectus Part I.

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

The Securities and Exchange Commission has not approved or disapproved
of the Trust units or passed upon the adequacy or accuracy of this prospectus.

Any contrary representation is a criminal offense.

THE TRUST
--------------------------------------------------------------------------------
GENERAL. Each Trust is a unit investment trust issued under the name Van
Kampen Merritt Insured Income Trust, Van Kampen American Capital Insured Income
Trust, Van Kampen Insured Income Trust or Van Kampen Focus Portfolios Insured
Income Trust. Your Trust was created under the laws of the State of New York
pursuant to a Trust Indenture and Agreement (the "Trust Agreement"), dated the
Date of Deposit among Van Kampen Funds Inc., as Sponsor, American Portfolio
Evaluation Services, a division of Van Kampen Investment Advisory Corp., as
Evaluator, and The Bank of New York, as Trustee, or their predecessors.
The Trust may be an appropriate medium for investors who desire to
participate in a portfolio of long-term taxable fixed income securities issued
after July 18, 1984 with greater diversification than they might be able to
acquire individually. Diversification of the Trust's assets will not eliminate
the risk of loss always inherent in the ownership of Bonds. For a breakdown of
the portfolio, see "Portfolio" in Prospectus Part I. In addition, Bonds of the
type initially deposited in the portfolio of the Trust are often not available
in small amounts and may, in the case of any privately placed Bonds, be
available only to institutional investors.
On the Date of Deposit, the Sponsor deposited the Bonds with the Trustee.
The Bonds initially consisted of delivery statements relating to contracts for
their purchase and cash, cash equivalents and/or irrevocable letters of credit
issued by a financial institution. Thereafter, the Trustee, in exchange for the
Bonds, delivered to the Sponsor evidence of ownership of the Units. Unless
otherwise terminated as provided herein, the Trust Agreement will terminate at
the end of the calender year prior to the fiftieth anniversary of its execution
(the twentieth anniversary for intermediate term Trusts).
Each Unit initially offered represents a fractional undivided interest in
the principal and net income of the Trust. To the extent that any Units are
redeemed by the Trustee, the fractional undivided interest in the Trust
represented by each Unit will increase, although the actual interest in the
Trust will remain unchanged. Units will remain outstanding until redeemed by
Unitholders or until the termination of the Trust Agreement.
OBJECTIVE AND BOND SELECTION. The objective of the Trust is to provide
income and conservation of capital by initially investing in a professionally
selected portfolio consisting of long-term or intermediate term corporate bonds,
taxable municipal bonds or U.S. government obligations. There is, of course, no
guarantee that the Trust will achieve its objective. The Trust may be an
appropriate investment vehicle for investors who desire to participate in a
portfolio of fixed income bonds with greater diversification than they might be
able to acquire individually.
Insurance guaranteeing the timely payment, when due, of all principal and
interest on the Bonds in the Trust has been obtained from a bond insurance
company. For information relating to insurance on the Bonds, see "Insurance on
the Bonds". Neither the Public Offering Price nor any evaluation of Units for
purposes of repurchases or redemptions reflects any element of value for the
insurance obtained by the Trust unless Bonds are in default in payment of
principal or interest or in significant risk of such default. See "Public
Offering--Offering Price". In addition, these bonds are often not available in
small amounts.
In order for Bonds to be eligible for insurance, they must have credit
characteristics which would qualify them for at least the Standard & Poor's
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 Ratings" in the Information Supplement). Insurance is
not a substitute for the basic credit of an issuer, but supplements the existing
credit and provides additional security. If an issue is accepted for insurance,
a non-cancellable policy for the prompt payment of interest and principal on the
Bonds, when due, is issued by the insurer. A monthly premium is paid by the
Trust for the insurance obtained by it. The Trustee has the right to obtain
permanent insurance from a Portfolio Insurer in connection with the sale of a
Bond 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 Bond. Accordingly, any Bond in a Trust is
eligible to be sold on an insured basis. All Bonds insured by a Portfolio
Insurer or by a Preinsured Bond Insurer receive a "AAA" rating by Standard &
Poor's. Standard & Poor's describes securities it rates "AAA" as having "the
highest rating assigned by Standard & Poor's to a debt obligation. Capacity to
pay interest and repay principal is extremely strong." See "Insurance on the
Bonds".
In selecting Bonds for the Trust, the Sponsor considered the following
factors, among others: (a) the prices of the Bonds relative to other bonds of
comparable quality and maturity, (b) the diversification of Bonds 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 Bonds and (d) whether the
debt obligations were issued after July 18, 1984.
TAXABLE MUNICIPAL BONDS. Your Trust may invest in taxable municipal bonds.
States, municipalities and public authorities issue these bonds to raise money
for a variety of purposes. In selecting bonds, we seek to diversify your
portfolio by bond purpose. This section briefly describes different bond types
to help you better understand your investment. We list the types of bonds in
your portfolio. We also describe these bonds in greater detail in the
Information Supplement.
General obligation bonds are backed by the general taxing power of the
issuer. The issuer secures these bonds by pledging its faith, credit and
unlimited taxing power for the payment of principal and interest.
Revenue bonds are payable only from the revenue of a specific project or
authority. They are not supported by the issuer's general power to levy taxes.
The risk of default in payment of interest or principal increases if the income
of the related project falters because that income is the only source of
payment. All of the following bonds are revenue bonds.
Airport bonds are obligations of issuers that own and operate airports. The
ability of the issuer to make payments on these bonds primarily depends on the
ability of airlines to meet their obligations under use agreements. Due to
increased competition, deregulation, increased fuel costs and other factors,
some airlines may have difficulty meeting these obligations.
Certificates of participation are generally a type of municipal lease
obligation. Lease payments of a governmental entity secure payments on these
bonds. These payments depend on the governmental entity budgeting appropriations
for the lease payments. A governmental body cannot obligate future governments
to appropriate for or make lease payments, but governments typically promise to
take action necessary to include lease payments in their budgets. If a
government fails to budget for or make lease payments, sufficient funds may not
exist to pay interest or principal on these bonds.
Health care bonds are obligations of issuers that derive revenue from
hospitals and hospital systems. The ability of these issuers to make payments on
bonds depends on factors such as facility occupancy levels, demand for services,
competition resulting from hospital mergers and affiliations, the need to reduce
costs, government regulation, cost of malpractice insurance and claims, and
government financial assistance (such as Medicare and Medicaid).
Public building bonds finance the cost of acquiring, leasing, building or
improving public buildings such as offices, recreation facilities, convention
centers, police stations, correctional institutions and parking garages. The
ability of the issuers to make payments on these bonds depends on factors such
as the government budgeting sufficient funds to make lease or mortgage payments
on the facility, user fees or rents, costs of maintenance and decreases in use
of the facility.
Tax district bonds are obligations secured by a pledge of taxing power by a
municipality, such as tax increment financing or tax allocation bonds. These
bonds are similar to general obligation bonds. Unlike general obligation bonds,
however, the municipality pledges revenues from a specific tax to pay these
bonds. If the tax cannot support payment or interest and principal, a
municipality may need to raise the related tax to pay these bonds. An inability
to raise the tax could have an adverse affect on these bonds.
Transportation bonds are obligations of issuers that own and operate public
transit systems, ports, highways, turnpikes, bridges and other transportation
systems. The ability of these issuers to make payments on these bonds depends on
variations in use, the degree of government subsidization, competition from
other forms of transportation and increased costs. Port authorities derive
revenues primarily from fees imposed on ships using the port facilities. These
fees can fluctuate depending on the local economy and competition from air, rail
and truck transportation. Increased fuel costs, alternative transportation modes
and competition from toll-free bridges and roads will impact revenues of issuers
that operate bridges, roads or tunnels.
PUBLIC UTILITY BONDS. Your Trust may also invest in public utility bonds.
Utilities consist of gas, water, telephone and electricity. Some utilities may
own or operate nuclear generating facilities. Utilities are generally subject to
extensive regulation by state utility commissions which establish rates and the
appropriate rate of return on an approved asset base.
MORE ABOUT THE BONDS. In addition to describing the purpose of the bonds,
we also list other information about the bonds in the "Portfolio" in Prospectus
Part I. This information relates to other characteristics of the bonds. This
section briefly describes some of these characteristics.
Original issue discount bonds were initially issued at a price below their
face (or par) value. These bonds typically pay a lower interest rate than
comparable bonds that were issued at or above their par value. In a stable
interest rate environment, the market value of these bonds tends to increase
more slowly in early years and in greater increments as the bonds approach
maturity. The issuers of these bonds may be able to call or redeem a bond before
its stated maturity date and at a price less than the bond's par value.
Zero coupon bonds are a type of original issue discount bond. These bonds
do not pay any current interest during their life. If you own this type of bond,
you have the right to receive a final payment of the bond's par value at
maturity. The price of these bonds often fluctuates greatly during periods of
changing market interest rates compared to bonds that make current interest
payments. The issuers of certain of these bonds can call the bond at a price
below the bond's par value.
"When, as and if issued" bonds are bonds that trade before they are
actually issued. This means that we can only deliver them to your Trust "when,
as and if" the bonds are actually issued. Delivery of these bonds may be delayed
or may not occur. Interest on these bonds does not begin accruing to your Trust
until we deliver the bond to the Trust. You may have to adjust your tax basis if
we deliver any of these bonds after the expected delivery date. Any adjustment
would reflect interest that accrued between the time you purchased your units
and the delivery of the bonds to your Trust. This could lower your first year
estimated current return. You may experience gains or losses on these bonds from
the time you purchase units even though your Trust has not yet received them.

RISK FACTORS. All investments involve risk. This section describes the main
risks that can impact the value of bonds in your Trust. You should understand
these risks before you invest. If the value of the bonds falls, the value of
your units will also fall. We cannot guarantee that your Trust will achieve its
objective or that your investment return will be positive over any period.
Market risk is the risk that the value of the bonds in your Trust will
fluctuate. This could cause the value of your units to fall below your original
purchase price or below the par value. Market value fluctuates in response to
various factors. These can include changes in interest rates, inflation, the
financial condition of a bond's issuer or insurer, perceptions of the issuer or
insurer, or ratings on a bond. Even though we carefully supervise your
portfolio, you should remember that we do not manage your portfolio. Your Trust
will not sell a bond solely because the market value falls as is possible in a
managed fund.
Interest rate risk is the risk that the value of bonds will fall if
interest rates increase. Bonds typically fall in value when interest rates rise
and rise in value when interest rates fall. Bonds with longer periods before
maturity are often more sensitive to interest rate changes.
Credit risk is the risk that a bond's issuer or insurer is unable to meet
its obligation to pay principal or interest on the bond.
Call risk is the risk that the issuer prepays or "calls" a bond before its
stated maturity. An issuer might call a bond if interest rates fall and the bond
pays a higher interest rate or if it no longer needs the money for the original
purpose. If an issuer calls a bond, your Trust will distribute the principal to
you but your future interest distributions will fall. You might not be able to
reinvest this principal at as high a yield. A bond's call price could be less
than the price your Trust paid for the bond and could be below the bond's par
value. This means that you could receive less than the amount you paid for your
units. If enough bonds in your Trust are called, your Trust could terminate
early. We list the first date that the issuer can call each bond in the
portfolio in Prospectus Part I along with the price the issuer would have to
pay.
Bond quality risk is the risk that a bond will fall in value if a rating
agency decreases the bond's rating. Bond concentration risk is the risk that
your Trust is less diversified because it concentrates in a particular type of
bond. When a certain type of bond makes up 25% or more of a Trust, the Trust is
considered to be "concentrated" in that bond type. We describe the different
bond types above.
Reduced diversification risk is the risk that your Trust will become
smaller and less diversified as bonds are sold, are called or mature. This could
increase your risk of loss and increase your share of Trust expenses.
Liquidity risk is the risk that the value of a bond will fall if trading in
the bond is limited or absent. No one can guarantee that a liquid trading market
will exist for any bond because these bonds generally trade in the
over-the-counter market (they are not listed on a securities exchange).
Litigation and legislation risk is the risk that future litigation or
legislation could affect the value of your Trust. Litigation could challenge an
issuer's authority to issue or make payments on bonds.
NO FDIC GUARANTEE. An investment in your Trust is not a deposit of any bank
and is not insured or guaranteed by the Federal Deposit Insurance Corporation or
any other government agency.

ESTIMATED CURRENT AND LONG-TERM RETURNS
--------------------------------------------------------------------------------
The Estimated Current Returns and the Estimated Long-Term Returns are set
forth in the Prospectus Part I. Estimated Current Return is calculated by
dividing the estimated net annual interest income per Unit by the Public
Offering Price. The estimated net annual interest income per Unit will vary with
changes in fees and expenses of the Trust and with the principal prepayment,
redemption, maturity, exchange or sale of Bonds. The Public Offering Price will
vary with changes in the price of the Bonds. Accordingly, there is no assurance
that the present Estimated Current Return will be realized in the future.
Estimated Long-Term Return is calculated using a formula which (1) takes into
consideration, and determines and factors in the relative weightings of, the
market values, yields (which takes into account the amortization of premiums and
the accretion of discounts) and estimated retirements of the Bonds and (2) takes
into account the expenses and sales charge associated with Units. Since the
value and estimated retirements of the Bonds and the expenses of a Trust will
change, there is no assurance that the present Estimated Long-Term Return will
be realized in the future. The Estimated Current Return and Estimated Long-Term
Return are expected to differ because the calculation of Estimated Long-Term
Return reflects the estimated date and amount of principal returned while the
Estimated Current Return calculation includes only net annual interest income
and Public Offering Price.
In order to acquire certain Bonds, it may be necessary for the Sponsor or
Trustee to pay amounts covering accrued interest on the Bonds which exceed the
amounts which will be made available through cash furnished by the Sponsor on
the Date of Deposit. This cash may exceed the interest which would accrue to the
First Settlement Date. The Trustee has agreed to pay for any amounts necessary
to cover any excess and will be reimbursed when funds become available from
interest payments on the related Bonds.

PUBLIC OFFERING
--------------------------------------------------------------------------------
GENERAL. Units are offered at the Public Offering Price. The secondary
market public offering price is based on the bid prices of the Bonds, the sales
charge described below, cash, if any, in the Principal Account plus accrued
interest, if any. The minimum purchase is one Unit. In connection with fully
disclosed transactions with the Sponsor, the minimum purchase is the number of
Units stated in the contract between the Sponsor and the related broker or
agent.
The secondary market sales charge is computed as described in the following
table based upon the estimated long-term return life of the Trust's portfolio:

YEARS TO MATURITY SALES CHARGE
------------------ --------------
1 1.010%
2 1.523
3 2.041
4 2.302
5 2.564
6 2.828
7 3.093
8 3.627
9 4.167
10 4.384
11 4.603
12 4.712
13 4.822
14 4.932
15 5.042
16 5.152
17 5.263
18 5.374
19 5.485
20 5.597
21 to 30 5.708

For purposes of computation of the estimated long-term return life, Bonds
will be deemed to mature on their expressed maturity dates unless: (a) the Bonds
have been called for redemption or are subject to redemption at an earlier call
date, in which case this call date will be deemed to be the maturity date; or
(b) the Bonds are subject to a "mandatory tender", in which case the mandatory
tender will be deemed to be the maturity date. The sales charges in the above
table are expressed as a percentage of the aggregate bid prices of the Bonds.
Expressed as a percent of the Public Offering Price, the sales charge on the
Trust consisting entirely of Bonds with 15 years to maturity would be 4.80%.
Any reduced sales charge is the responsibility of the selling broker,
dealer or agent. The Sponsor will, however, increase the concession or agency
commission for quantity purchases.
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 Funds Inc. and its affiliates, dealers and their
affiliates and vendors providing services to the Sponsor may purchase Units at
the Public Offering Price less the applicable dealer concession.
A portion of the sales charge is waived for certain accounts described in
this paragraph. Purchases by these accounts are subject only to the portion of
the deferred sales charge that is retained by the Sponsor. Please refer to the
section called "Wrap Fee and Advisory Accounts" for additional information on
these purchases. Units may be purchased in the primary or secondary market at
the Public Offering Price (for purchases which do not qualify for a sales charge
reduction for quantity purchases) less the concession the Sponsor typically
allows to brokers and dealers for purchases by (1) investors who purchase Units
through registered investment advisers, certified financial planners and
registered broker-dealers who in each case either charge periodic fees for
brokerage services, 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 spouse or child 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 Units will vary from the
amounts stated under "Summary of Essential Financial Information" in Prospectus
Part I in accordance with fluctuations in the prices of the Bonds. The price of
Units on the Date of Deposit was determined by adding the applicable sales
charge to the aggregate offering price of the Bonds and dividing the sum by the
number of Units outstanding. This price determination was made on the basis of
an evaluation of the Bonds prepared by Interactive Data Corporation, a firm
regularly engaged in the business of evaluating, quoting or appraising
comparable securities. During the initial offering period, the Evaluator will
value the Bonds as of the Evaluation Time on days the New York Stock Exchange is
open for business and will adjust the Public Offering Price of Units
accordingly. This Public Offering Price will be effective for all orders
received at or prior to the Evaluation Time on each such day. The "Evaluation
Time" is the close of regular trading on the New York Stock Exchange on each day
that the Exchange is open for trading. Orders received by the Trustee, Sponsor
or any Underwriter for purchases, sales or redemptions after that time, or on a
day when the New York Stock Exchange is closed, will be held until the next
determination of price. The secondary market Public Offering Price per Unit will
be equal to the aggregate bid price of the Bonds plus the applicable secondary
market sales charge and dividing the sum by the number of Units outstanding. For
secondary market purposes, this computation will be made by the Evaluator as of
the Evaluation Time for each day on which any Unit is tendered for redemption
and as necessary. The offering price of Bonds may be expected to average
approximately 0.35-1% more than the bid price.
The aggregate price of the Bonds is determined on the basis of bid prices
or offering prices, as is appropriate, (a) on the basis of current market prices
obtained from dealers or brokers who customarily deal in bonds comparable to
those held by the Trust; (b) if these prices are not available, on the basis of
current market prices for comparable bonds; (c) by causing the value of the
Bonds to be determined by others engaged in the practice of evaluation, quoting
or appraising comparable bonds; or (d) by any combination of the above. Market
prices of the Bonds will generally fluctuate with changes in market interest
rates. Unless Bonds are in default in payment of principal or interest or in
significant risk of default, the Evaluator will not attribute any value to the
insurance obtained by the Trust.
The Evaluator will consider in its evaluation of Bonds which are in default
in payment of principal or interest or, in the Sponsor's opinion, in significant
risk of default (the "Defaulted Bonds") the value of any insurance guaranteeing
interest and principal payments. The value of the insurance will be equal to the
difference between (i) the market value of Defaulted Bonds assuming the exercise
of the right to obtain Permanent Insurance (less the insurance premiums and
related expenses attributable to the purchase of Permanent Insurance) and (ii)
the market value of Defaulted Bonds not covered by Permanent Insurance. In
addition, the Evaluator will consider the ability of a Portfolio Insurer to meet
its commitments under any insurance policy, including commitments to issue
Permanent Insurance. No value has been ascribed to insurance obtained by an
Insured Trust, if any, as of the date of this Prospectus.
A person will become the owner of Units on the date of settlement provided
payment has been received. Cash, if any, made available to the Sponsor prior to
the date of settlement for the purchase of Units may be used in the Sponsor's
business and may be deemed to be a benefit to the Sponsor, subject to the
limitations of the Securities Exchange Act of 1934.
ACCRUED INTEREST. Accrued interest is an accumulation of unpaid interest on
securities which generally is paid semi-annually, although the Trust accrues
interest daily. Because of this, the Trust always has an amount of interest
earned but not yet collected by the Trustee. For this reason, with respect to
sales settling after the First Settlement Date, the proportionate share of
accrued interest to the settlement date is added to the Public Offering Price of
Units of Series 44 and subsequent series of the Trust. Unitholders will receive
the amount of accrued interest paid on their Units on the next distribution
date. In an effort to reduce the accrued interest which would have to be paid by
Unitholders, the Trustee will advance the amount of accrued interest to the
Sponsor as the Unitholder of record as of the First Settlement Date.
Consequently, the accrued interest added to the Public Offering Price of Units
will include only accrued interest from the First Settlement Date to the date of
settlement, less any distributions from the Interest Account after the First
Settlement Date. Because of the varying interest payment dates of the Bonds,
accrued interest at any point in time will be greater than the amount of
interest actually received by the 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.
ACCRUED INTEREST (ACCRUED INTEREST TO CARRY). Added to the Public Offering
Price of Units for Series 34 and prior Series is accrued interest to carry.
Accrued interest to carry consists of two elements. The first element arises as
a result of accrued interest which is the accumulation of unpaid interest on a
bond from the last day on which interest thereon was paid. Interest on
Obligations in the Trust is actually paid either monthly or semi-annually to the
Trust. However, interest on the Obligations in the Trust is accounted for daily
on an accrual basis. Because of this, the Trust always has an amount of interest
earned but not yet collected by the Trustee because of coupons that are not yet
due. For this reason, the Public Offering Price of Units will have added to it
the proportionate share of accrued and undistributed interest to the date of
settlement.
The second element of accrued interest to carry arises because of the
structure of the Interest Account. The Trustee has no cash for distribution to
Unitholders until it receives interest payments on the Obligations in the Trust.
The Trustee is obligated to provide its own funds, at times, in order to advance
interest distributions. The Trustee will recover these advancements when such
interest is received. Interest Account balances are established so that it will
not be necessary on a regular basis for the Trustee to advance its own funds in
connection with such interest distributions. The Interest Account balances are
also structured so that there will generally be positive cash balances and since
the funds held by the Trustee will be used by it to earn interest thereon, it
benefits thereby. If the Unitholder sells or redeems all or a portion of his
Units or if the Obligations in the Trust are sold or otherwise removed or if the
Trust is liquidated, he will receive at that time his proportionate share of the
accrued interest to carry computed to the settlement date in the case of sale or
liquidation and to the date of tender in the case of redemption. Purchased and
Accrued Interest. Included in the Public Offering Price of Units for Series
35-43 is Purchased Interest and accrued interest as described below.
PURCHASED AND ACCRUED INTEREST. Added to the Public Offering Price of Units
for Series 35-43 is Purchased Interest and accrued interest as described below.
Purchased Interest. Purchased Interest is a portion of the unpaid interest
that has accrued on the Obligations from the later of the last payment date on
the Obligations or the date of issuance thereof through the First Settlement
Date and is included in the calculation of the Public Offering Price. Purchased
Interest will be distributed to Unitholders as Units are redeemed or Obligations
mature or are called. See "Summary Of Essential Financial Information" in
Prospectus Part I for the amount of Purchased Interest per Unit for each Trust.
Purchased Interest is an element of the price Unitholders will receive in
connection with the sale or redemption of Units prior to the termination of the
Trust.
Accrued Interest. Accrued Interest is an accumulation of unpaid interest on
securities which generally is paid semi-annually, although a Trust accrues such
interest daily. Because of this, a Trust always has an amount of interest earned
but not yet collected by the Trustee. For this reason, the Public Offering Price
of Units will have added to it the proportionate share of accrued interest to
the date of settlement. Unitholders will receive on the next distribution date
of a Trust the amount, if any, of accrued interest paid on their Units. As
indicated in "Purchased Interest", accrued interest as of the First Settlement
Date includes Purchased Interest. In an effort to reduce the amount of Purchased
Interest which would otherwise have to be paid by Unitholders, the Trustee may
advance a portion of such accrued interest to the Sponsor as the Unitholder of
record as of the First Settlement Date. Consequently, the amount of accrued
interest to be added to the Public Offering Price of Units will include only
accrued interest from the First Settlement Date to the date of settlement (other
than the Purchased Interest already included therein), less any distributions
from the Interest Account subsequent to the First Settlement Date. See "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
Purchased Interest and accrued interest from the purchaser of his Units. Since
the Trustee has the use of the funds (including Purchased Interest) held in the
Interest Account for distributions to Unitholders and since such Account is
non-interest-bearing to Unitholders, the Trustee benefits thereby.
UNIT DISTRIBUTION. Units will be distributed to the public by
broker-dealers and others at the Public Offering Price, plus accrued interest.
The Sponsor intends to qualify Units for sale in a number of states.
Broker-dealers or others will be allowed a concession or agency commission in
connection with the distribution of Units equal to 70% of the applicable sales
charge.
Certain commercial banks may be making Units available to their customers
on an agency basis. A portion of the sales charge paid by these customers (equal
to the agency commission referred to above) is retained by or remitted to the
banks. Any discount provided to investors will be borne by the selling dealer or
agent. The Sponsor reserves the right to reject, in whole or in part, any order
for the purchase of Units and to change the amount of the concession or agency
commission to dealers and others from time to time.
SPONSOR COMPENSATION. Broker-dealers will receive a gross sales commission
equal to the sales charge applicable to the transaction involved. See "Public
Offering--General". The Sponsor will receive from the broker-dealers the excess
of this gross sales commission over the amounts set forth in the previous
section.
In addition, the Sponsor may have realized a profit or loss, as a result of
the difference between the price paid for the Bonds by the Sponsor and the cost
of the Bonds to the Trust. The Sponsor or its affiliates may also have realized
profits or losses with respect to Bonds which were acquired by the Sponsor from
underwriting syndicates of which they were members. The Sponsor has not
participated as sole underwriter or as manager or as a member of the
underwriting syndicates from which the Bonds in the Trust were acquired. The
Sponsor may further realize profit or loss as a result of possible fluctuations
in the market value of the Bonds since all proceeds received from purchasers of
Units (excluding dealer concessions or agency commissions allowed, if any) will
be retained by the Sponsor. The Sponsor will also realize profits or losses in
the amount of any difference between the price at which Units are purchased and
the price at which Units are resold in connection with maintaining a secondary
market for Units and will also realize profits or losses resulting from a
redemption of repurchased Units at a price above or below the purchase price.
Broker-dealers of the Trust, banks and/or others are eligible to
participate in a program in which such firms receive from the Sponsor a nominal
award for each of their representatives who have sold a minimum number of units
of unit investment trusts created by the Sponsor during a specified time period.
In addition, at various times the Sponsor may implement other programs under
which the sales forces of such firms may be eligible to win other nominal awards
for certain sales efforts, or under which the Sponsor will reallow to any such
firms that sponsor sales contests or recognition programs conforming to criteria
established by the Sponsor, or participate in sales programs sponsored by the
Sponsor, an amount not exceeding the total applicable sales charges on the sales
generated by such persons at the public offering price during such programs.
Also, the Sponsor in its discretion may from time to time pursuant to objective
criteria established by the Sponsor pay fees to qualifying firms for certain
services or activities which are primarily intended to result in sales of Units
of the 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.
MARKET FOR UNITS. Although not obligated to do so, the Sponsor intends to
maintain a market for Units and offer to purchase Units at prices, subject to
change at any time, based upon the aggregate bid prices of the Bonds plus
accrued interest and any principal cash on hand, less any amounts representing
taxes or other governmental charges payable out of the Trust and less any
accrued Trust expenses. If the supply of Units exceeds demand or if some other
business reason warrants it, the Sponsor may either discontinue all purchases of
Units or discontinue purchases of Units at these prices. If a market is not
maintained and the Unitholder cannot find another purchaser, a Unitholder will
be able to dispose of Units by tendering them to the Trustee for redemption at
the Redemption Price. See "Rights of Unitholders--Redemption of Units". A
Unitholder who wishes to dispose of his Units should inquire of his broker as to
current market prices in order to determine whether there is in any price in
excess of the Redemption Price and, if so, the amount thereof. The Trustee will
notify the Sponsor of any tender of Units for redemption. If the Sponsor's bid
in the secondary market at that time equals or exceeds the Redemption Price per
Unit, it may purchase the Units not later than the day on which the Units would
otherwise have been redeemed by the Trustee.

WRAP FEE AND ADVISORY ACCOUNTS
--------------------------------------------------------------------------------
Units may be available for purchase in connection with "wrap fee" accounts
and other similar accounts. You should consult your financial professional to
determine whether you can benefit from these accounts. For these purchases you
generally only pay the portion of the sales charge that is retained by your
Trust's Sponsor, Van Kampen Funds Inc. You should consult the "Public
Offering--General" section for specific information on this and other sales
charge discounts.

RIGHTS OF UNITHOLDERS
--------------------------------------------------------------------------------
DISTRIBUTIONS OF INTEREST AND PRINCIPAL. Interest received by the Trust,
pro rated on an annual basis, will be distributed monthly unless a Unitholder
elects to receive quarterly or semi-annual distributions. Certain Trusts do not
offer all distribution options. Please refer to Prospectus Part I. The plan of
distribution selected by a Unitholder will remain in effect until changed.
Unitholders who purchase Units in the secondary market will receive
distributions in accordance with the election of the prior owner. Unitholders
may change their distribution plan by indicating the change on a card which may
be obtained from the Trustee and return the card to the Trustee with their
certificates and other documentation required by the Trustee. Certificates
should be sent by registered or certified mail to avoid their being lost or
stolen. If the card and certificate are properly presented to the Trustee, the
change will become effective on the first day after the next semi-annual record
date and will remain effective until changed.
Interest received by the Trust, including that part of the proceeds of any
disposition of Bonds which represents accrued interest, is credited by the
Trustee to the Interest Account. Other receipts are credited to the Principal
Account. After deduction of amounts sufficient to reimburse the Trustee, without
interest, for any amounts advanced and paid to the Sponsor as the Unitholder of
record as of the First Settlement Date, interest received will be distributed on
each distribution date to Unitholders of record as of the preceding record date.
All distributions will be net of estimated expenses. Funds in the Principal
Account will be distributed on each semi-annual distribution date to Unitholders
of record as of the preceding semi-annual record date. The Trustee is not
required to pay interest on funds held in the Principal or Interest Account (but
may itself earn interest thereon and therefore benefits from the use of these
funds) nor to make a distribution from the Principal Account unless the amount
available for distribution therein shall equal at least $1.00 per Unit. However,
should the amount available for distribution in the Principal Account equal or
exceed $10.00 per Unit, the Trustee will make a special distribution from the
Principal Account on the next monthly distribution date to Unitholders of record
on the related monthly record date.
Because interest payments are not received by the Trust at a constant rate
throughout the year, interest distributions may be more or less than the amount
credited to the Interest Account as of the record date. For the purpose of
minimizing fluctuations in interest distributions, the Trustee is authorized to
advance amounts necessary to provide interest distributions of approximately
equal amounts. The Trustee is reimbursed for these advances from funds in the
Interest Account on the next record date. Persons who purchase Units between a
record date and a distribution date will receive their first distribution on the
second distribution date after the purchase, under the applicable plan of
distribution.
REINVESTMENT OPTION. Unitholders may elect to have distributions on their
Units automatically reinvested in shares of certain Van Kampen mutual funds
which are registered in the Unitholder's state of residence (the "Reinvestment
Funds"). Each Reinvestment Fund has investment objectives that differ from those
of the Trust. The prospectus relating to each Reinvestment Fund describes its
investment policies and the procedures to follow to begin reinvestment. A
Unitholder may obtain a prospectus for the Reinvestment Funds from Van Kampen
Funds Inc. at 1 Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, Illinois
60181-5555.
After becoming a participant in a reinvestment plan, each Trust
distribution will automatically be applied on the applicable distribution date
to purchase shares of the applicable Reinvestment Fund at a net asset value
computed on such date. Unitholders with an existing Guaranteed Reinvestment
Option (GRO) Program account (whereby a sales charge is imposed on distribution
reinvestments) may transfer their existing account into a new GRO account which
allows purchases of Reinvestment Fund shares at net asset value. Confirmations
of all reinvestments will be mailed to the Unitholder by the Reinvestment Fund.
A participant may elect to terminate his or her reinvestment plan and receive
future distributions in cash by notifying the Trustee in writing at least five
days before the next distribution date. Each Reinvestment Fund, its sponsor and
investment adviser have the right to terminate its reinvestment plan at any
time.
REDEMPTION OF UNITS. A Unitholder may redeem all or a portion of his Units
by tender to the Trustee, at its Unit Investment Trust Division, 101 Barclay
Street, 20th Floor, New York, New York 10286, of the certificates representing
the Units to be redeemed, duly endorsed or accompanied by proper instruments of
transfer with signature guaranteed (or by providing satisfactory indemnity, such
as in connection with lost, stolen or destroyed certificates) and by payment of
applicable governmental charges, if any. Redemption of Units cannot occur until
certificates representing the Units or satisfactory indemnity have been received
by the Trustee. No later than seven calendar days following satisfactory tender,
the Unitholder will receive an amount for each Unit equal to the Redemption
Price per Unit next computed after receipt by the Trustee of the tender of
Units. The "date of tender" is deemed to be the date on which Units are received
by the Trustee, except that as regards Units received after the Evaluation Time
on days of trading on the New York Stock Exchange, the date of tender is the
next day on which that Exchange is open and the Units will be deemed to have
been tendered to the Trustee on that day for redemption at the Redemption Price.
Under Internal Revenue Service regulations, the Trustee is required to
withhold a specified percentage of a Unit redemption if the Trustee has not
received the Unitholder's tax identification number as required by such
regulations. Any amount withheld is transmitted to the Internal Revenue Service
and may be recovered by the Unitholder only when filing a return. Under normal
circumstances the Trustee obtains the Unitholder's tax identification number
from the selling broker. However, at any time a Unitholder elects to tender
Units for redemption, the Unitholder should provide a tax identification number
to the Trustee in order to avoid this possible "back-up withholding".
The Redemption Price per Unit (as well as the secondary market Public
Offering Price) will be determined on the basis of the bid price of the Bonds as
of the Evaluation Time on days of trading on the New York Stock Exchange on the
date any such determination is made. The Evaluator determines the Redemption
Price per Unit on days Units are tendered for redemption. The Redemption Price
per Unit is the pro rata share of each Unit on the basis of (i) the cash on hand
in the Trust or moneys in the process of being collected, (ii) the value of the
Bonds based on the bid prices of the Bonds, except for cases in which the value
of insurance has been included, (iii) accrued interest, less (a) amounts
representing taxes or other governmental charges and (b) the accrued Trust
expenses. The Evaluator may determine the value of the Bonds by employing any of
the methods set forth in "Public Offering--Offering Price". In determining the
Redemption Price per Unit no value will be assigned to the portfolio insurance
maintained on the Bonds in the Trust unless the Bonds are in default in payment
of principal or interest or in significant risk of default. For a description of
the situations in which the Evaluator may value the insurance obtained by the
Trust, see "Public Offering--Offering Price". Accrued interest paid on
redemption shall be withdrawn from the Interest Account or, if the balance
therein is insufficient, from the Principal Account. All other amounts will be
withdrawn from the Principal Account. Units so redeemed shall be cancelled.
The price at which Units may be redeemed could be less than the price paid
by the Unitholder and may be less than the par value of the Bonds represented by
the Units redeemed. The Trustee may sell Bonds to cover redemptions. When Bonds
are sold, the size and diversity of the Trust will be reduced. Sales may be
required at a time when Bonds would not otherwise be sold and might result in
lower prices than might otherwise be realized.
The right of redemption may be suspended and payment postponed for any
period during which the New York Stock Exchange is closed, other than for
customary weekend and holiday closings, or during which the SEC determines that
trading on that Exchange is restricted or an emergency exists, as a result of
which disposal or evaluation of the Bonds is not reasonably practicable, or for
other periods as the SEC may by order permit. Under certain extreme
circumstances the Sponsor may apply to the SEC for an order permitting a full or
partial suspension of the right of Unitholders to redeem their Units.
CERTIFICATES. Ownership of Units is evidenced in book entry form unless a
Unitholder makes a written request to the Trustee that ownership be in
certificate form. Units are transferable by making a written request to the
Trustee and, in the case of Units in certificate form, by presentation and
surrender of the certificate to the Trustee properly endorsed or accompanied by
a written instrument or instruments of transfer. A Unitholder must sign the
written request, or certificate transfer instrument, exactly as his name appears
on the records of the Trustee and on the face of any certificate with the
signature guaranteed by a participant in the Securities Transfer Agents
Medallion Program ("STAMP") or a signature guaranty program accepted by the
Trustee. The Trustee may require additional documents such as, but not limited
to, trust instruments, certificates of death, appointments as executor or
administrator or certificates of corporate authority. Certificates will be
issued in denominations of one Unit or any multiple thereof. Although no such
charge is now made, the Trustee may require a Unitholder to pay a reasonable fee
for each certificate re-issued or transferred and to pay any governmental charge
that may be imposed in connection with each transfer or interchange. Destroyed,
stolen, mutilated or lost certificates will be replaced upon delivery to the
Trustee of satisfactory indemnity, evidence of ownership and payment of expenses
incurred. Mutilated certificates must be surrendered to the Trustee for
replacement.
REPORTS PROVIDED. Unitholders will receive a statement of interest and
other receipts received for each distribution. For as long as the Sponsor deems
it to be in the best interest of Unitholders, the accounts of the Trust will be
audited annually by independent certified public accountants and the report of
the accountants will be furnished to Unitholders upon request. Within a
reasonable period of time after the end of each year, the Trustee will furnish
to each person who was a registered Unitholder during that year a statement
describing the interest and principal received on the Bonds, actual Trust
distributions, Trust expenses, a list of the Bonds and other Trust information.
Unitholders will be furnished the Evaluator's evaluations of the Bonds upon
request.

INSURANCE ON THE BONDS
--------------------------------------------------------------------------------
Insurance has been obtained guaranteeing prompt payment of interest and
principal, when due, in respect of the Bonds in the Trust. An insurance policy
obtained by the Trust is non-cancelable and will continue in force so long as
the Trust is in existence, the respective Portfolio Insurer is still in business
and the Bonds described in the policy continue to be held by the Trust. Any
portfolio insurance premium for an Insured Trust is paid by the Trust on a
monthly basis. The premium for any Preinsured Bond insurance has been paid by
the issuer, by a prior owner of the Bonds or the Sponsor and any policy is
non-cancelable and will continue in force so long as the Bonds so insured are
outstanding and the Preinsured Bond Insurer remains in business. The Portfolio
Insurers and the Preinsured Bond Insurers are described in "Portfolio" in
Prospectus Part I and the notes thereto. More detailed information regarding
insurance on the Bonds and the Preinsured Bond and Portfolio Insurers is
included in the Information Supplement. See "Additional Information".
The portfolio insurance obtained by the Trust guarantees the timely payment
of principal and interest on the Bonds when they fall due. For this purpose,
"when due" generally means the stated maturity date for the payment of principal
and interest. However, in the event (a) an issuer defaults in the payment of
principal or interest, (b) an issuer enters into a bankruptcy proceeding or (c)
the maturity of the Bond is accelerated, the affected Portfolio Insurer has the
option to pay the outstanding principal amount of the Bond plus accrued interest
to the date of payment and thereby retire the Bond from the Trust prior to the
Bond's stated maturity date. The insurance does not guarantee the market value
of the Bonds or the value of the Units. The Trustee, upon the sale of a Bond
covered under a portfolio insurance policy has the right to obtain permanent
insurance with respect to the Bond (i.e., insurance to maturity of the Bond
regardless of the identity of the holder) (the "Permanent Insurance") upon the
payment of a single predetermined insurance premium and expenses from the
proceeds of the sale of the Bond. It is expected that the Trustee would exercise
the right to obtain Permanent Insurance only if upon exercise the Trust would
receive net proceeds in excess of the sale proceeds if the Bonds were sold on an
uninsured basis.
Because the Bonds are insured by Portfolio Insurers or Preinsured Bond
Insurers as to the timely payment of principal and interest, when due, and on
the basis of the various reinsurance agreements in effect, Standard & Poor's has
assigned to the Units of the Trust its "AAA" investment rating. This rating will
be in effect for a period of thirteen months from the Date of Deposit and will,
unless renewed, terminate at the end of such period. See "Description of
Ratings" in the Information Supplement. This rating should not be construed as
an approval of the offering of the Units by Standard & Poor's or as a guarantee
of the market value of the Trust or of the Units.
Each Portfolio Insurer is subject to regulation by the department of
insurance in the state in which it is qualified to do business. Such regulation,
however, is no guarantee that each Portfolio Insurer will be able to perform on
its contract of insurance in the event a claim should be made. At the date
hereof, it is reported that no claims have been submitted or are expected to be
submitted to any of the Portfolio Insurers which would materially impair the
ability of any such company to meet its commitment pursuant to any contract of
insurance. The information relating to each Portfolio Insurer has been furnished
by such companies. The financial information with respect to each Portfolio
Insurer appears in reports filed with state insurance regulatory authorities and
is subject to audit and review by such authorities. No representation is made
herein as to the accuracy or adequacy of such information or as to the absence
of material adverse changes in such information subsequent to the dates thereof.

TRUST ADMINISTRATION
--------------------------------------------------------------------------------
THE SPONSOR. Van Kampen Funds Inc. is the Sponsor of your Trust. We are a
subsidiary of Van Kampen Investments Inc. (which is an indirect subsidiary of
Morgan Stanley Dean Witter & Co.). We specialize in underwriting and
distribution of investment companies with roots in money management dating back
to 1926. We are a Delaware corporation, a registered broker-dealer and a member
of the National Association of Securities Dealers, Inc. You can contact us by
calling (630) 684-6000 or at our offices listed on the back cover of this
prospectus. As of November 30, 1999, our total stockholders' equity was
$141,554,861 (audited). If we fail to or cannot perform our duties under the
trust agreement or become bankrupt, the Trustee may appoint a new sponsor,
continue to operate your Trust without a sponsor, or terminate your Trust and
distribute the liquidation proceeds. Van Kampen Funds Inc. and your Trust have
adopted a code of ethics requiring Van Kampen's employees who have access to
information on Trust transactions to report personal securities transactions.
The purpose of the code is to avoid potential conflicts of interest and to
prevent fraud, deception or misconduct with respect to your Trust.
TRUSTEE. The Trustee is The Bank of New York, a trust company organized
under the laws of New York. The Bank of New York has its unit investment trust
division offices at 101 Barclay Street, New York, New York 10286, telephone
(800) 221-7668. The Bank of New York is subject to supervision and examination
by the Superintendent of Banks of the State of New York and the Board of
Governors of the Federal Reserve System, and its deposits are insured by the
Federal Deposit Insurance Corporation to the extent permitted by law. Additional
information regarding the Trustee is set forth in the Information Supplement,
including the Trustee's qualifications and duties, its ability to resign, the
effect of a merger involving the Trustee and the Sponsor's ability to remove and
replace the Trustee. See "Additional Information".
PORTFOLIO ADMINISTRATION. The Trust is not a managed fund and, except as
provided in the Trust Agreement, Bonds generally will not be sold or replaced.
The Sponsor may, however, direct that Bonds be sold in certain limited
situations to protect the Trust based on advice from the Evaluator. These
situations may include default in interest or principal payments on the Bonds or
other obligations of an issuer, an advanced refunding or institution of certain
legal proceedings. In addition, the Trustee may sell Bonds designated by the
Evaluator for purposes of redeeming Units or payment of expenses. The Evaluator
will consider a variety of factors in designating Bonds to be sold including
interest rates, market value and marketability. Except in limited circumstances,
the Trustee must reject any offer by an issuer to issue bonds in exchange or
substitution for the Bonds (such as a refunding or refinancing plan). The
Trustee will promptly notify Unitholders of any exchange or substitution. The
Information Supplement contains a more detailed description of circumstances in
which Bonds may be sold or replaced. See "Additional Information".
REPLACEMENT BONDS. No assurance can be given that a Trust will retain its
present size or composition because Bonds may be sold, redeemed or mature from
time to time and the proceeds will be distributed to Unitholders and will not be
reinvested. In the event of a failure to deliver any Bond that has been
purchased under a contract ("Failed Bonds"), the Sponsor is authorized under the
Trust Agreement to direct the Trustee to acquire other bonds ("Replacement
Bonds") to make up the original portfolio of the Trust. Replacement Bonds must
be purchased within 20 days after delivery of the notice of the failed contract
and the purchase price (exclusive of accrued interest) may not exceed the amount
of funds reserved for the purchase of the Failed Bonds. The Replacement Bonds
must (i) be long-term or intermediate term (as applicable) 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 Bonds 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 the
interest 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
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 Bonds; (vi) maintain the
Standard & Poor's AAA rating; and (vii) be eligible for (and when acquired be
insured under) the insurance obtained by the Trust. The Trustee shall notify all
Unitholders of a Trust within five days after the acquisition of a Replacement
Bond and shall make a pro rata distribution of the amount, if any, by which the
cost of the Failed Bond exceeded the cost of the Replacement Bond plus accrued
interest. If Failed Bonds are not replaced, the Sponsor will refund the sales
charge attributable to the Failed Bonds to all Unitholders of the Trust and
distribute the principal and accrued interest (at the coupon rate of the Failed
Bonds to the date of removal from the Trust) attributable to the Failed Bonds
within 30 days after removal. If Failed Bonds are not replaced, the Estimated
Net Annual Interest Income per Unit would be reduced and the Estimated Current
Return and Estimated Long-Term Return might be lowered. Unitholders may not be
able to reinvest their proceeds in other securities at a yield equal to or in
excess of the yield of the Failed Bonds.
AMENDMENT OF TRUST AGREEMENT. The Sponsor and the Trustee may amend the
Trust Agreement without the consent of Unitholders to correct any provision
which may be defective or to make other provisions that will not adversely
affect the interest of the Unitholders (as determined in good faith by the
Sponsor and the Trustee). The Trust Agreement may not be amended to increase the
number of Units or to permit the acquisition of Bonds in addition to or in
substitution for any of the Bonds initially deposited in the Trust, except for
the substitution of certain refunding Bonds. The Trustee will notify Unitholders
of any amendment.
TERMINATION OF TRUST AGREEMENT. A Trust will terminate upon the redemption,
sale or other disposition of the last Bond held in the Trust. A Trust may also
be terminated at any time by consent of Unitholders of 51% of the Units then
outstanding or by the Trustee when the value of the Trust is less than 20% of
the original principal amount of Bonds. The Trustee will notify each Unitholder
of any termination within a reasonable time and will then liquidate any
remaining Bonds. The sale of Bonds upon termination may result in a lower amount
than might otherwise be realized if the sale was not required at that time. For
this reason, among others, the amount realized by a Unitholder upon termination
may be less than the principal amount of Bonds per Unit or value at the time of
purchase. The Trustee will distribute to each Unitholder his share of the
balance of the Interest and Principal Accounts after deduction of costs,
expenses or indemnities. The Unitholder will receive a final distribution
statement with this distribution. When the Trustee in its sole discretion
determines that any amounts held in reserve are no longer necessary, it will
distribute these amounts to Unitholders. The Information Supplement contains
further information regarding termination of a Trust. See "Additional
Information".
LIMITATION ON LIABILITIES. The Sponsor, Evaluator and Trustee shall be
under no liability to Unitholders for taking any action or for refraining from
taking any action in good faith pursuant to the Trust Agreement, or for errors
in judgment, but shall be liable only for their own willful misfeasance, bad
faith or gross negligence (negligence in the case of the Trustee) in the
performance of their duties or by reason of their reckless disregard of their
obligations and duties hereunder. The Trustee shall not be liable for
depreciation or loss incurred by reason of the sale by the Trustee of any of the
Bonds. In the event of the failure of the Sponsor to act under the Trust
Agreement, the Trustee may act thereunder and shall not be liable for any action
taken by it in good faith under the Trust Agreement. The Trustee is not liable
for any taxes or governmental charges imposed on the Bonds, on it as Trustee
under the Trust Agreement or on a 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
and Sponsor may rely on any evaluation furnished by the Evaluator and have no
responsibility for the accuracy thereof. Determinations by the Evaluator shall
be made in good faith upon the basis of the best information available to it;
provided, however, that the Evaluator shall be under no liability to the
Trustee, Sponsor or Unitholders for errors in judgment.

FEDERAL TAX STATUS
--------------------------------------------------------------------------------
For purposes of the following discussions and opinions, it is assumed that
the Obligations are debt for federal income tax purposes 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:
The Trust is not an association taxable as a corporation for United States
Federal income tax purposes. Each Unitholder will be considered the owner of a
pro rata portion of each of the Trust's assets for Federal income tax purposes
under Subpart E, Subchapter J of Chapter 1 of the Internal Revenue Code of 1986
(the "Code"). Each Unitholder will be considered to have received his pro rata
share of income derived from each such asset when such income is considered to
be received by the Trust. Each Unitholder will also be required to include in
taxable income for Federal income tax purposes, original issue discount with
respect to his interest in any Obligations held by the Trust at the same time
and in the same manner as though the Unitholder were the direct owner of such
interest.
Each Unitholder will have a taxable event when an Obligation of the Trust is
disposed of (whether by sale, exchange, liquidation, redemption, payment at
maturity or otherwise) 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. 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 the Trust at a premium must be reduced by the
annual amortization of bond premium which the Unitholder has properly elected to
amortize under Section 171 of the Code. The tax 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 the Trust are treated as bonds that were originally issued at an
original issue discount provided, pursuant to a Treasury Regulation (the
"Regulation") issued on December 28, 1992, that the amount of original issue
discount determined under Section 1286 of the Code is not less than a "de
minimis" amount as determined thereunder (as discussed below under "Original
Issue Discount"). Because the Treasury Bonds represent interests in "stripped"
bonds, a Unitholder's initial cost for his pro rata portion of each Treasury
Bond held by the Trust (determined at the time he acquires his Units, in the
manner described above) shall be treated as its "purchase price" by the
Unitholder. Original issue discount is effectively treated as interest for
Federal income tax purposes, and the amount of original issue discount in this
case is generally the difference between the bond's purchase price and its
stated redemption price at maturity. A Unitholder will be required to include in
gross income for each taxable year the sum of his daily portions of original
issue discount attributable to the Treasury Bonds held by the Trust as such
original issue discount accrues and will, in general, be subject to Federal
income tax with respect to the total amount of such original issue discount that
accrues for such year even though the income is not distributed to the
Unitholders during such year to the extent it is not less than a "de minimis"
amount as determined under the Regulation. 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 of and accretion of original issue discount.
LIMITATIONS ON DEDUCTIBILITY OF TRUST EXPENSES BY UNITHOLDERS. Each
Unitholder's pro rata share of each expense paid by the Trust is deductible by
the Unitholder to the same extent as though the expense had been paid directly
by him. 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 Trust 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 be determined by the period of time
the Unitholder held his Unit and the period of time the Trust held the
Obligation. The Internal Revenue Service Restructuring and Reform Act of 1998
(the "1998 Tax Act") provides that for taxpayers other than corporations, net
capital gain (which is defined as net long-term capital gain over net short-term
capital loss for the taxable year) realized from property (with certain
exclusions ) is subject to a maximum marginal stated tax rate of 20% (10% in the
case of certain taxpayers in the lowest tax bracket). Capital gain or loss is
long-term if the holding period for the asset is more than one year, and is
short-term if the holding period for the asset is one year or less. The date on
which a Unit is acquired (i.e., the "trade date") is excluded for purposes for
determining the holding period of the Unit. Capital gains realized from assets
held for one year or less are taxed at the same rates as ordinary income. The
tax basis reduction requirements of the Code relating to amortization of bond
premium may, under certain 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.
In addition, please note that capital gains may be recharacterized 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 their own tax
advisors regarding the effect of this provision on their Units.
The 1997 Act includes provisions that treat certain transactions designed to
reduce or eliminate risk of loss and opportunities for gain (e.g., short sales,
offsetting notional principal contracts, futures or forward contracts, or
similar transactions) as constructive sales for purposes of recognition of gain
(but not loss) and for purposes of determining the holding period. Unit holders
should consult their own tax advisors with regard to any such constructive sales
rules.
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.
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), 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 Revenue Reconciliation Act of 1993 includes a
provision which eliminates the exemption from United States taxation, including
withholding taxes, for certain "contingent interest." The provision applies to
interest received after December 31, 1993. No opinion is expressed herein
regarding the potential applicability of this provision and whether United
States taxation or withholding taxes could be imposed with respect to income
derived from the Units as a result thereof. Unitholders and prospective
investors should consult with their tax advisers regarding the potential effect
of this provision on their investment in Units.
GENERAL. Each Unitholder (other than a foreign investor who has properly
provided the certifications described above) will be requested to provide the
Unitholder's taxpayer identification number to the Trustee and to certify that
the Unitholder has not been notified that payments to the Unitholder are subject
to back-up withholding. If the proper taxpayer identification number and
appropriate certification are not provided when requested, distributions by the
Trust to such Unitholder including amounts received upon the redemption of the
Units will be subject to back-up withholding.
In the opinion of special counsel to the Trust for New York tax matters, the
Trust is not an association taxable as a corporation and the income of the 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.

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

RISK FACTORS
The Trusts include certain types of bonds described below. Accordingly, an
investment in a Trust should be made with an understanding of the
characteristics of and risks associated with such bonds. Neither the Sponsor nor
the Trustee shall be liable in any way for any default, failure or defect in any
of the Bonds.
PUBLIC UTILITY ISSUES. The Trust contains bonds of public utility issuers.
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 Bonds in the
portfolio to make payments of principal and/or interest on such Bonds.
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. 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.
The California Public Utility Commission ("CPUC") is in the process of
deregulating the electric utility industry in California. This change will
eventually result in full competition between electric utilities and independent
power producers in the generation and sale of power to all customers in
California by the year 2002. The California electrical industry promotes
competition and allows customers a right to choose their electrical supplier.
Deregulation of the electric utility industry in California could have a
significant adverse effect on electric utility stocks of California issuers.
Furthermore, the move toward full competition in California could indicate that
similar changes may be made in other states in the future which could negatively
impact the profitability of electric utilities. Further deregulation could
adversely affect the issuers of certain of the Bonds in the portfolio. In view
of the uncertainties regarding the CPUC deregulation plan, it is unclear what
effect, if any, that full competition will have on electric utilities in
California or whether similar changes will be adopted in other states.
Certain of the issuers of the Bonds may own or operate nuclear generating
facilities. Governmental authorities may from time to time review existing, and
impose additional, requirements governing the licensing, construction and
operation of nuclear power plants. Nuclear generating projects in the electric
utility industry have experienced substantial cost increases, construction
delays and licensing difficulties. These have been caused by various factors,
including inflation, high financing costs, required design changes and rework,
allegedly faulty construction, objections by groups and governmental officials,
limits on the ability to finance, reduced forecasts of energy requirements and
economic conditions. This experience indicates that the risk of significant cost
increases, delays and licensing difficulties remains present through to
completion and achievement of commercial operation of any nuclear project. Also,
nuclear generating units in service have experienced unplanned outages or
extensions of scheduled outages due to equipment problems or new regulatory
requirements sometimes followed by a significant delay in obtaining regulatory
approval to return to service. A major accident at a nuclear plant anywhere,
such as the accident at a plant in Chernobyl, could cause the imposition of
limits or prohibitions on the operation, construction or licensing of nuclear
units in the United States.
Other general problems of the gas, water, telephone and electric utility
industry (including state and local joint action power agencies) include
difficulty in obtaining timely and adequate rate increases, difficulty in
financing large construction programs to provide new or replacement facilities
during an inflationary period, rising costs of rail transportation to transport
fossil fuels, the uncertainty of transmission service costs for both interstate
and intrastate transactions, changes in tax laws which adversely affect a
utility's ability to operate profitably, increased competition in service costs,
recent reductions in estimates of future demand for electricity and gas in
certain areas of the country, restrictions on operations and increased cost and
delays attributable to environmental considerations, uncertain availability and
increased cost of capital, unavailability of fuel for electric generation at
reasonable prices, including the steady rise in fuel costs and the costs
associated with conversion to alternate fuel sources such as coal, availability
and cost of natural gas for resale, technical and cost factors and other
problems associated with construction, licensing, regulation and operation of
nuclear facilities for electric generation, including among other considerations
the problems associated with the use of radioactive materials and the disposal
of radioactive wastes, and the effects of energy conservation. Each of the
problems referred to could adversely affect the ability of the issuers of any
utility bonds in the Trust to make payments due on these bonds.
In view of the pending investigations and the other uncertainties discussed
above, there can be no assurance that any company's share of the full cost of
nuclear units under construction ultimately will be recovered in rates or of the
extent to which a company could earn an adequate return on its investment in
such units. The likelihood of a significantly adverse event occurring in any of
the areas of concern described above varies, as does the potential severity of
any adverse impact. It should be recognized, however, that one or more of such
adverse events could occur and individually or collectively could have a
material adverse impact on the financial condition or the results of operations
of a company's ability to make interest and principal payments on its
outstanding debt.
TAXABLE MUNICIPAL ISSUES. Certain bonds in the Trust may consist of taxable
obligations of municipal issuers. 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 Bonds 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
bonds is not exempt from Federal income taxation under Section 103 of the Code.
Thus, owners of taxable municipal bonds generally must include interest on such
bonds in gross income for Federal income tax purposes and treat such interest as
ordinary income.
Certain of the Bonds may be obligations which are payable from and secured
by revenues derived from the ownership and operation of facilities such as
airports, bridges, turnpikes, port authorities, convention centers and arenas.
The major portion of an airport's gross operating income is generally derived
from fees received from signatory airlines pursuant to use agreements which
consist of annual payments for leases, occupancy of certain terminal space and
service fees. Airport operating income may therefore be affected by the ability
of the airlines to meet their obligations under the use agreements. 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 Bonds may be health care revenue bonds. Ratings of bonds
issued for health care facilities are often based on feasibility studies that
contain projections of occupancy levels, revenues and expenses. A facility's
gross receipts and net income available for debt service may be affected by
future events and conditions including, among other things, demand for services
and the ability of the facility to provide the services required, physicians'
confidence in the facility, management capabilities, competition with other
health care facilities, efforts by insurers and governmental agencies to limit
rates, legislation establishing state rate-setting agencies, expenses, the cost
and possible unavailability of malpractice insurance, the funding of Medicare,
Medicaid and other similar third party payor programs, government regulation and
the termination or restriction of governmental financial assistance, including
that associated with Medicare, Medicaid and other similar third party payor
programs. 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 portfolio of the Trust; however,
because of the insurance obtained by the Trust, the "AAA" rating of the Units of
the Trust would not be affected.
ZERO COUPON BONDS. Certain of the bonds in the Trust may be "zero coupon"
bonds. Zero coupon bonds are purchased at a deep discount because the buyer
receives only the right to receive a final payment at the maturity of the bond
and does not receive any periodic interest payments. The effect of owning deep
discount bonds which do not make current interest payments (such as the zero
coupon bonds) is that a fixed yield is earned not only on the original
investment but also, in effect, on all discount earned during the life of such
income on the bond at a rate as high as the implicit yield on the discount bond,
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.

INSURANCE ON THE BONDS
Insurance has been obtained by the Trust, by the issuer of Bonds in the
Trust, by a prior owner of such Bonds, or by the Sponsor prior the deposit of
such Bonds guaranteeing prompt payment of interest and principal, when due, in
respect of the bonds in such Trust. See "The Trust--Objective and Bond
Selection" in the Prospectus. Each insurance policy obtained by the Trust, is
non-cancellable and will continue in force so long as such Trust is in
existence, the respective Portfolio Insurer is still in business and the Bonds
described in such policy continue to be held by such Trust. Non-payment of
premiums on a policy obtained by the Trust will not result in the cancellation
of insurance but will force the insurer to take action against the Trustee to
recover premium payments due it. The Trustee in turn will be entitled to recover
such payments from such Trust. Premium rates for each issue of Bonds protected
by 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 bonds has
been paid by such issuer, and any such policy or policies are non-cancellable
and will continue in force so long as the Bonds so insured are outstanding and
the Portfolio Insurer remains in business. If the provider of an original
issuance insurance policy is unable to meet its obligations under such policy or
if the rating assigned to the claims-paying ability of any such insurer
deteriorates, the Portfolio Insurers have no obligation to insure any issue
adversely affected by either of the above described events.
The aforementioned Trust insurance guarantees the timely payment of
principal and interest on the Bonds 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 a
Bond defaults in the payment of principal or interest on such Bond, (b) such
issuer enters into a bankruptcy proceeding or (c) the maturity of such Bond is
accelerated, the 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 Bond plus accrued interest to the date of
such payment and thereby retire the Bond from the Trust prior to such Bond's
stated maturity date. The insurance does not guarantee the market value of the
Bonds or the value of the Units. Insurance obtained by a Trust is only effective
as to Bonds owned by and held in such Trust. In the event of a sale of any such
Bond by the Trustee, such insurance terminates as to such Bond on the date of
sale.
Pursuant to an irrevocable commitment of the Portfolio Insurers, the
Trustee, upon the sale of a Bond covered under a portfolio insurance policy
obtained by the Trust, has the right to obtain permanent insurance with respect
to such Bond (i.e., insurance to maturity of the Bonds regardless of the
identity of the holder thereof) (the "Permanent Insurance") upon the payment of
a single predetermined insurance premium and any expenses related thereto from
the proceeds of the sale of such Bond. Accordingly, any Bond in 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 Bond proceeds less the insurance
premium and related expenses attributable to the Permanent Insurance) from such
sale in excess of the sale proceeds if such Bonds were sold on an uninsured
basis.The insurance premium with respect to each Bond eligible for Permanent
Insurance would be determined based upon the insurability of each Bond as of the
Date of Deposit and would not be increased or decreased for any change in the
creditworthiness of each Bond.
The Sponsor believes that the Permanent Insurance option provides an
advantage to the Trust in that each Bond 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 Bond so sold (which is not the case in connection
with any value attributable to such Trust's portfolio insurance). See "Public
Offering--Offering Price" in the Prospectus. Because any such insurance value
may be realized in the market value of the Bond upon the sale thereof upon
exercise of the Permanent Insurance option, the Sponsor anticipates that (a) in
the event the Trust were to be comprised of a substantial percentage of Bonds 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--Redemption of Units" in the Prospectus) and (b) at the time of
termination of the Trust, if the Trust were holding defaulted Bonds or Bonds in
significant risk of default, the Trust would not need to hold such Bonds until
their respective maturities in order to realize the benefits of the Trust's
portfolio insurance. (See "Fund Administration--Termination of Trust Agreement"
in the Prospectus.)
Except as indicated below, insurance obtained by the Trust has no effect on
the price or redemption value of Units. It is the present intention of the
Evaluator to attribute a value for such insurance (including the right to obtain
Permanent Insurance) for the purpose of computing the price or redemption value
of Units if the Bonds covered by such insurance are in default in payment of
principal or interest or in significant risk of such default. The value of the
insurance will be equal to the difference between (i) the market value of a Bond
which is in default in payment of principal or interest or in significant risk
of such default assuming the exercise of the right to obtain Permanent Insurance
(less the insurance premium and related expenses attributable to the purchase of
Permanent Insurance) and (ii) the market value of such Bond not covered by
Permanent Insurance. See "Public Offering--Offering Price" in the Prospectus for
a more complete description of the Trust's method of valuing defaulted Bonds
which have a significant risk of default.
The portfolio insurance policies obtained by the Trust were issued by either
AMBAC Assurance or CapMAC. The other policy (or commitment therefor) obtained by
a Bond issuer was issued by AMBAC Assurance. See "The Trust--Objective and Bond
Selection" in the Prospectus.
Capital Markets Assurance Corporation ("CapMAC") is a New York-domiciled
monoline stock insurance company which engages only in the business of financial
guaranty and surety insurance. CapMAC is licensed in all 50 states in addition
to the District of Columbia, the Commonwealth of Puerto Rico and the territory
of Guam. CapMAC insures structured asset-backed, corporate, municipal and other
financial obligations in the U.S. and international capital markets. CapMAC also
provides financial guarantee reinsurance for structured asset-backed, corporate,
municipal and other financial obligations written by other major insurance
companies.
CapMAC's claims-paying ability is rated "Aaa" by Moody's Investors Service,
Inc. ("Moody's"), "AAA" by Standard & Poor's, "AAA" by Duff & Phelps Credit
Rating Co. ("Duff & Phelps") and "AAA" by Nippon Investors Service, Inc. Such
ratings reflect only the views of the respective rating agencies, are not
recommendations to buy, sell or hold securities and are subject to revision or
withdrawal at any time by such rating agencies.
Pursuant to a merger of a subsidiary of MBIA Inc. with and into CapMAC
Holdings Inc., CapMAC became an indirect wholly-owned subsidiary of MBIA Inc. on
February 17, 1998. MBIA Inc., through its wholly-owned subsidiary, MBIA
Insurance Corporation, is a financial guaranty insurer of municipal bonds and
structured finance transactions. MBIA Insurance Corporation has a claims paying
rating of triple-A from Moody's Investor Service, Inc., Standard & Poor's
Ratings Services and Fitch IBCA, Inc. (formerly Fitch Investors Service, L.P.).
Pursuant to a reinsurance agreement, it is anticipated that CapMAC will cede all
of its net insured risks, as well as its unearned premiums and contingency
reserves, to MBIA Insurance Corporation and that MBIA Insurance Corporation will
reinsure CapMAC's net outstanding exposure. NEITHER MBIA INC. NOR ANY OF ITS
STOCKHOLDERS IS OBLIGATED TO PAY ANY CLAIMS UNDER ANY POLICY ISSUED BY CAPMAC OR
ANY DEBTS OF CAPMAC OR TO MAKE ADDITIONAL CAPITAL CONTRIBUTIONS TO CAPMAC.
CapMAC is regulated by the Superintendent of Insurance of the State of New
York. In addition, CapMAC is subject to regulation by the insurance laws and
regulations of the other jurisdictions in which it is licensed. Such insurance
laws regulate, among other things, the amount of net exposure per risk that
CapMAC may retain, capital transfers, dividends, investment of assets, changes
in control, transactions with affiliates and consolidations and acquisitions.
CapMAC is subject to periodic regulatory examinations by the same regulatory
authorities.
CapMAC's obligations under the Policy(s) may be reinsured. Such reinsurance
does not relieve CapMAC of any of its obligations under the Policy(s).
THE POLICY IS NOT COVERED BY THE PROPERTY/CASUALTY INSURANCE SECURITY FUND
SPECIFIED IN ARTICLE 76 OF THE NEW YORK INSURANCE LAW.
As of December 31, 1995 and 1996, CapMAC had qualified statutory capital
(which consists of policyholders' surplus, statutory capital, and contingency
reserves) of approximately $260 million and $240 million, respectively, and had
not incurred any debt obligations. As of September 30, 1997, CapMAC had
qualified statutory capital of $278.6 million and had not incurred any debt
obligations. Article 69 of the New York State Insurance Law requires CapMAC to
establish and maintain the contingency reserve, which is available to cover
claims under policies issued by CapMAC.
Copies of CapMAC's financial statements prepared in accordance with statutory
accounting standards, which differ from generally accepted accounting
principles, are filed with the Insurance Department of the State of New York and
are available upon request. CapMAC is located at 885 Third Avenue, New York, New
York 10022, and its telephone is (212) 755-1155.
Effective July 14, 1997, AMBAC Indemnity Corporation changed its name to
AMBAC Assurance Corporation ("AMBAC Assurance"). AMBAC Assurance is a
Wisconsin-domiciled stock insurance corporation regulated by the Office of the
Commissioner of Insurance of the State of Wisconsin and licensed to do business
in 50 states, the District of Columbia and the Commonwealth of Puerto Rico, with

capital of approximately $1,715,481,691 (unaudited) as of March 31, 1998.
Statutory capital consists of AMBAC Assurance's policyholders' surplus and
statutory contingency reserve. AMBAC Assurance is a wholly owned subsidiary of
AMBAC Financial Group, Inc., a 100% publicly-held company. Moody's Investors
Service, Inc. and Standard & Poor's have both assigned a triple-A claims-paying
ability rating to AMBAC Assurance.
Copies of its financial statements prepared in accordance with statutory
accounting standards are available from AMBAC Assurance. The address of AMBAC
Assurance's administrative offices and its telephone number are One State Street
Plaza, 17th Floor, New York, New York, 10004 and (212) 668-0340.
AMBAC Assurance has entered into quota share reinsurance agreements under
which a percentage of the insurance underwritten pursuant to certain municipal
bond insurance programs of AMBAC Assurance has been and will be assumed by a
number of foreign and domestic unaffiliated reinsurers.
MBIA Insurance Corporation ("MBIA") is the principal operating subsidiary of
MBIA Inc., a New York Stock Exchange listed company. MBIA Inc. is not obligated
to pay the debts of or claims against MBIA. MBIA is domiciled in the State of
New York and licensed to do business in and subject to regulation under the laws
of all fifty states, the District of Columbia, the Commonwealth of the Northern
Mariana Islands, the Commonwealth of Puerto Rico, the Virgin Islands of the
United States and the Territory of Guam. MBIA has two European branches, one in
the Republic of France and the other in the Kingdom of Spain. New York has laws
prescribing minimum capital requirements, limiting classes and concentrations of
investments and requiring the approval of policy rates and forms. State laws
also regulate the amount of both the aggregate and individual risks that may be
insured, the payment of dividends by the insurer, changes in control and
transactions among affiliates. Additionally, the Insurer is required to maintain
contingency reserves on its liabilities in certain amounts and for certain
periods of time.
Effective February 17, 1998, MBIA, Inc. acquired all of the outstanding stock
of CapMAC, through a merger with its parent, CapMAC Holdings, Inc. Pursuant to a
reinsurance agreement, CapMAC has ceded all of its net insured risks (including
any amounts due but unpaid from third party reinsurers), as well as its unearned
premiums and contingency reserves to MBIA. MBIA, Inc. is not obligated to pay
debts of or claims against CapMAC.
As of December 31, 1998, the insurer had admitted assets of $6.5 billion
(audited), total liabilities of $4.2 billion (audited), and total capital and
surplus of $2.3 billion (audited) determined in accordance with statutory
accounting practices prescribed or permitted by insurance regulatory
authorities. As of June 30, 1999, MBIA had admitted assets of $6.8 billion
(unaudited), total liabilities of $4.5 billion (unaudited), and total capital
and surplus of $2.3 billion (unaudited), determined in accordance with statutory
accounting practices prescribed or permitted by insurance regulatory
authorities. Copies of MBIA's financial statements prepared in accordance with
statutory accounting practices are available from MBIA. The address of MBIA is
113 King Street, Armonk, New York 10504.
Effective December 31, 1989, MBIA, Inc. acquired Bond Investors Group, Inc.
On January 5, 1990, MBIA acquired all of the outstanding stock of Bond Investors
Group, Inc., the parent of Bond Investors Guaranty Insurance Company (BIG), now
known as MBIA Insurance Corp. of Illinois. Through a reinsurance agreement, BIG
has ceded all of its net insured risks, as well as its unearned premium and
contingency reserves, to MBIA and MBIA has reinsured BIG's net outstanding
exposure.
MBIA Inc. is actively managing a high-priority Year 2000 (Y2K) program. The
company has established an independent Y2K testing lab in its Armonk
headquarters, with a committee of business unit managers overseeing the project.
MBIA has a budget of $1.13 million for its 1998-2000 Y2K efforts. Expenditures
are proceeding as anticipated, and MBIA does not expect the project budget to
materially exceed this amount. MBIA has initiated a comprehensive Y2K plan that
includes assessment, remediation, testing and contingency planning. This plan

Moody's Investors Service, Inc. rates all bond issues insured by MBIA "Aaa"
and short-term loans "MIG-1," both designated to be of the highest quality.
Standard & Poor's rates all new issues insured by MBIA "AAA" Prime Grade.
Moody's, Standard & Poor's and Fitch IBCA, Inc. (formerly Fitch Investors
Service, L.P.), all rate the claims paying ability of MBIA as "Triple A."
The Moody's Investors Service, Inc. rating of MBIA should be evaluated
independently of the Standard & Poor's rating of MBIA. No application has been
made to any other rating agency in order to obtain additional ratings on the
Obligations. The ratings reflect the respective rating agency's current
assessment of the creditworthiness of MBIA and its ability to pay claims on its
policies of insurance. Any further explanation as to the significance of the
above ratings may be obtained only from the applicable rating agency.
The above ratings are not recommendations to buy, sell or hold the
Obligations and such ratings may be subject to revision or withdrawal at any
time by the rating agencies. Any downward revision or withdrawal of either or
both ratings may have an adverse effect on the market price of the Obligations.

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.

subject to applicable statutory risk limitations. In addition, Financial
Security and FSA Maryland reinsure a portion of their liabilities under certain

obligations of Financial Security or FSA Maryland under any financial guaranty
insurance policy.

Because the Bonds are insured by CapMAC, MBIA or AMBAC Assurance 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 the 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.
The obtaining of this rating by the 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 Trust or of the Units.
An objective of portfolio insurance obtained by the Trust is to obtain a
higher yield on the Trust portfolio than would be available if all the Bonds in
such portfolio had Standard & Poor's "AAA" rating and yet at the same time to
have the protection of insurance of prompt payment of interest and principal,
when due (as more fully described above), on the Bonds. 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 a Bond, 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.

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

investment trusts are professionally distributed by leading financial firms
nationwide. 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 INFORMATION
The Trustee is The Bank of New York, a trust company organized under the laws
of New York. The Bank of New York has its unit investment trust division offices
at 101 Barclay Street, New York, New York 10286, telephone (800) 221-7668. The
Bank of New York is subject to supervision and examination by the Superintendent
of Banks of the State of New York and the Board of Governors of the Federal
Reserve System, and its deposits are insured by the Federal Deposit Insurance
Corporation to the extent permitted by law.
The duties of the Trustee are primarily ministerial in nature. It did not
participate in the selection of Bonds for the portfolios of any of the Trusts.
In accordance with the Trust Agreement, the Trustee shall keep proper books of
record and account of all transactions at its office for the Fund. Such records
shall include the name and address of, and the certificates issued by the Fund
to, every Unitholder of the Fund. Such books and records shall be open to
inspection by any Unitholder at all reasonable times during the usual business
hours. The Trustee shall make such annual or other reports as may from time to
time be required under any applicable state or Federal statute, rule or
regulation. The Trustee is required to keep a certified copy or duplicate
original of the Trust Agreement on file in its office available for inspection
at all reasonable times during the usual business hours by any Unitholder,
together with a current list of the Bonds held in the Fund.
Under the Trust Agreement, the Trustee or any successor trustee may resign
and be discharged of the trusts created by the Trust Agreement by executing an
instrument in writing and filing the same with the Sponsor. The Trustee or
successor trustee must mail a copy of the notice of resignation to all Fund
Unitholders then of record, not less than 60 days before the date specified in
such notice when such resignation is to take effect. The Sponsor upon receiving
notice of such resignation is obligated to appoint a successor trustee promptly.
If, upon such resignation, no successor trustee has been appointed and has
accepted the appointment within 30 days after notification, the retiring Trustee
may apply to a court of competent jurisdiction for the appointment of a
successor. The Sponsor may remove the Trustee and appoint a successor trustee as
provided in the Trust Agreement at any time with or without cause. Notice of
such removal and appointment shall be mailed to each Unitholder by the Sponsor.
Upon execution of a written acceptance of such appointment by such successor
trustee, all the rights, powers, duties and bonds of the original trustee shall
vest in the successor. The resignation or removal of a Trustee becomes effective
only when the successor trustee accepts its appointment as such or when a court
of competent jurisdiction appoints a successor trustee. Any corporation into
which a Trustee may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which a Trustee shall
be a party, shall be the successor trustee. The Trustee must be a banking
corporation organized under the laws of the United States or any state and
having at all times an aggregate capital, surplus and undivided profits of not
less than $5,000,000.

TERMINATION OF THE TRUST AGREEMENT
A Trust may be terminated at any time by consent of Unitholders 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 20% of the
original principal amount of Bonds.
A Trust will be liquidated by the Trustee in the event that a sufficient
number of Units not yet sold are tendered for redemption by the Underwriters,
including the Sponsor, so that the net worth of 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 Bond held in the Trust, but in
no event shall it continue beyond the end of the year preceding the fiftieth
anniversary of the Trust Agreement (twentieth anniversary for intermediate term
trusts). In the event of termination of the Trust, written notice thereof will
be sent by the Trustee to each Unitholder of the Trust at his address appearing
on the registration books of the Trust maintained by the Trustee, such notice
specifying the time or times at which the Unitholder may surrender his
certificate or certificates for cancellation. Within a reasonable time
thereafter the Trustee shall liquidate any Bonds 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 Bonds in the Trust upon termination may result in a lower amount than
might otherwise be realized if such sale were not required at such time. For
this reason, among others, the amount realized by a Unitholder upon termination
may be less than the principal amount or par amount of Bonds represented by the
Units held by such Unitholder. The Trustee shall then distribute to each
Unitholder his share of the balance of the Interest and Principal Accounts. With
such distribution the 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.

DESCRIPTION OF RATINGS
STANDARD & POOR'S, A DIVISION OF THE MCGRAW-HILL COMPANIES. A Standard &
Poor's corporate or municipal bond rating is a current assessment of the
creditworthiness of an obligor with respect to a specific debt bond. This
assessment of creditworthiness may take into consideration obligors such as
guarantors, insurers or lessees.
The bond rating is not a recommendation to purchase or sell a security,
inasmuch as it does not comment as to market price.
The ratings are based on current information furnished to Standard & Poor's
by the issuer and obtained by Standard & Poor's from other sources it considers
reliable. The ratings may be changed, suspended or withdrawn as a result of
changes in, or unavailability of, such information.
The ratings are based, in varying degrees, on the following considerations:

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

II. Nature of and provisions of the obligation.

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

AAA--This is the highest rating assigned by Standard & Poor's to a debt bond
and indicates an extremely strong capacity to pay principal and interest.
AA--Bonds rated AA also qualify as high-quality debt obligations. Capacity to
pay principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.
A--Bonds rated A have a strong capacity to pay principal and interest,
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions.
BBB--Bonds rated BBB are regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.
Plus (+) or Minus (-): To provide more detailed indications of credit
quality, the ratings from "AA" to "BBB" may be modified by the addition of a
plus or minus sign to show relative standing within the major rating categories.
Provisional Ratings: A provisional rating ("p") assumes the successful
completion of the project being financed by the issuance of the bonds being
rated and indicates that payment of debt service requirements is largely or
entirely dependent upon the successful and timely completion of the project.
This rating, however, while addressing credit quality subsequent to completion,
makes no comment on the likelihood of, or the risk of default upon failure of,
such completion. Accordingly, the investor should exercise his own judgment with
respect to such likelihood and risk.
MOODY'S INVESTORS SERVICE, INC. A brief description of the applicable
Moody's rating symbols and their meanings follows:
Aaa--Bonds which are rated Aaa are judged to be the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge". Interest payments are protected by a large, or by an exceptionally
stable, margin and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues. With the occasional
exception of oversupply in a few specific instances, the safety of obligations
of this class is so absolute that their market value is affected solely by money
market fluctuations.
Aa--Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuations of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in Aaa
securities. These Aa bonds are high grade, their market value virtually immune
to all but money market influences, with the occasional exception of oversupply
in a few specific instances.
A--Bonds which are rated A possess many favorable investment attributes and
are to be considered as higher medium grade obligations. Factors giving security
to principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future. The market
value of A-rated bonds may be influenced to some degree by credit circumstances
during a sustained period of depressed business conditions. During periods of
normalcy, bonds of this quality frequently move in parallel with Aaa and Aa
obligations, with the occasional exception of oversupply in a few specific
instances.
Baa--Bonds which are rated Baa are considered as medium grade obligations;
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
Moody's bond rating symbols may contain numerical modifiers of a generic
rating classification. The modifier 1 indicates that the bond ranks at the high
end of its category; the modifier 2 indicates a mid-range ranking; and the
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
Con--Bonds for which the security depends upon the completion of some act or
the fulfillment of some condition are rated conditionally. These are bonds
secured by (a) earnings of projects under construction, (b) earnings of projects
unseasoned in operating experience, (c) rentals which begin when facilities are
completed, or (d) payments to which some other limiting condition attaches.
Parenthetical rating denotes probable credit stature upon completion of
construction or elimination of basis of condition.
