VAN KAMPEN AMERICAN CAPITAL

Internet Trust, Series 9
Telecommunications Trust, Series 1
Health Care & Pharmaceuticals Trust, Series 1
Utility Trust, Series 1

The Fund. Van Kampen American Capital Equity Opportunity Trust, Series 90 (the
"Fund" ) is comprised of the underlying separate unit investment trusts
described above (the "Trusts" ). The Trusts offer investors the
opportunity to purchase Units representing proportionate interests in separate
fixed portfolios of actively traded equity securities issued by companies
diversified within a specific industry sector ("Equity Securities" or
"Securities" ). See "Trust Portfolios" . Unless terminated
earlier, the Trusts will terminate on the Mandatory Termination Date and any
Securities then held will, within a reasonable time thereafter, be liquidated
or distributed by the Trustee. Any Securities liquidated at termination will
be sold at the then current market value for such Securities; therefore, the
amount distributable in cash to a Unitholder upon termination may be more or
less than the amount such Unitholder paid for his Units. Upon liquidation,
Unitholders may choose to reinvest their proceeds into a new trust, if
available, at a reduced sales charge, to receive a cash distribution or to
receive a pro rata distribution of the Securities (if they own the requisite
number of Units).

Attention Foreign Investors. If you are not a United States citizen or
resident, distributions will generally be subject to U.S. federal withholding
taxes; however, under certain circumstances treaties between the United States
and other countries may reduce or eliminate such withholding tax. See "
Federal Taxation." Such investors should consult their tax advisers
regarding the imposition of U.S. withholding on distributions.

Objective of the Trusts. The objective of the Trusts is to provide the
potential for capital appreciation by investing in a portfolio of equity
securities diversified within a particular industry sector. See "
Objectives and Securities Selection" . There is, of course, no guarantee
that the objective of a Trust will be achieved.

Public Offering Price. The Public Offering Price of the Units during the
initial offering period and for secondary market transactions after the
initial offering period includes the aggregate underlying value of the
Securities, an initial sales charge, and cash, if any, in the Income and
Capital Accounts. The initial sales charge is computed as described under "
Public Offering--General" . Unitholders will also be subject to a deferred
sales charge as described under "Public Offering--General" . During the
initial offering period, the sales charge is reduced on a graduated scale for
sales involving at least 10,000 Units of a Trust. If Units were available for
purchase at the close of business on the day before the Initial Date of
Deposit, the Public Offering Price per Unit would have been that amount set
forth under "Summary of Essential Financial Information" . Except as
provided in "Public Offering--Unit Distribution" , the minimum purchase
is 100 Units. See "Public Offering" .

Additional Deposits. The Sponsor may, from time to time after the Initial Date
of Deposit, deposit additional Securities in the Trusts as provided under "
The Trusts" .

Units are not insured by the FDIC, are not deposits or other obligations of,
or guaranteed by, any depository institution or any government agency and are
subject to investment risk, including possible loss of the principal amount
invested.

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

Dividend and Capital Distributions. Distributions of dividends and capital, if
any, received by a Trust will be paid in cash on the Distribution Dates to
Unitholders of record on the record date as set forth in the "Summary of
Essential Financial Information" . The estimated initial distribution for
each Trust is set forth under "Summary of Essential Financial
Information" and will be made on _____ 25, 1998. Gross dividends received
by a Trust will be distributed to Unitholders. Expenses of a Trust will be
paid with proceeds from the sale of Securities. For the consequences of such
sales, see "Federal Taxation" . Additionally, upon surrender of Units
for redemption or termination of a Trust, the Trustee will distribute to each
Unitholder his pro rata share of the Trust's assets, less expenses, in the
manner set forth under "Rights of Unitholders--Distributions of Income and
Capital" .

Secondary Market For Units. Although not obligated to do so, the Sponsor
currently intends to maintain a market for Units and offer to repurchase such
Units at prices which are based on the aggregate underlying value of Equity
Securities (generally determined by the closing sale or bid prices of the
Securities) plus or minus cash, if any, in the Capital and Income Accounts. If
a secondary market is not maintained, a Unitholder may redeem Units at prices
based upon the aggregate underlying value of the Equity Securities plus or
minus a pro rata share of cash, if any, in the Capital and Income Accounts.
See "Rights of Unitholders--Redemption of Units" . Units sold or
tendered for redemption prior to such time as the entire deferred sales charge
on such Units has been collected will be assessed the amount of the remaining
deferred sales charge at the time of sale or redemption. A Unitholder
tendering 1,000 or more Units for redemption may request a distribution of
shares of Securities (reduced by customary transfer and registration charges)
in lieu of payment in cash. See "Rights of Unitholders--Redemption of
Units" .

Termination. The Trusts will terminate approximately two years following the
Initial Date of Deposit. At least 30 days prior to the Mandatory Termination
Date the Trustee will provide written notice thereof to all Unitholders and
will include with such notice a form to enable Unitholders to elect a
distribution of shares of the Securities (reduced by customary transfer and
registration charges) if such Unitholder owns at least 1,000 Units, rather
than to receive payment in cash for such Unitholder's pro rata share of the
amounts realized upon the disposition of such Securities. Unitholders will
receive cash in lieu of any fractional shares. To be effective, the election
form, and any other documentation required by the Trustee, must be returned to
the Trustee at least five business days prior to the Mandatory Termination
Date. Unitholders may elect to become Rollover Unitholders as described in
"Special Redemption and Rollover in New Trust" below. Rollover
Unitholders will not receive the final liquidation distribution but will
receive units of a new Aggressive Growth Series, if one is being offered.
Unitholders not electing the Rollover Option or a distribution of shares of
Securities will receive a cash distribution from the sale of the remaining
Securities within a reasonable time after a Trust is terminated. See "
Trust Administration--Amendment or Termination" . 

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

In the event that a distribution is made to Unitholders prior to a Trust's
termination, Unitholders will have such distributions reinvested into
additional Units of the Trust subject only to the remaining deferred sales
charge payments as set forth herein, if Units are available at the time of
reinvestment, or distributed in cash. See "Rights of
Unitholders--Reinvestment Option" . 

Special Redemption and Rollover in New Trust. The Sponsor currently
anticipates that new series of the Fund will be created throughout the year.
Unitholders will have the option, subject to any necessary regulatory
approval, of specifying by either Rollover Notification Date stated in "
Summary of Essential Financial Information" to have all of their Units
redeemed and the distributed Securities sold by the Trustee, in its capacity
as Distribution Agent, on the related Special Redemption Date. (Unitholders so
electing are referred to herein as "Rollover Unitholders" .) The
Distribution Agent will appoint the Sponsor as its agent to determine the
manner, timing and execution of sales of underlying Securities. The proceeds
of the redemption will then be invested in units of a new trust (the "New
Trust" ), if one is offered, at a reduced sales charge. The Sponsor may,
however, stop offering units of the New Trust at any time in its sole
discretion without regard to whether all the proceeds to be invested have been
invested. Cash which has not been invested on behalf of the Rollover
Unitholders in the New Trust will be distributed shortly after the related
Special Redemption Date. However, the Sponsor anticipates that sufficient
Units will be available, although moneys in the current Trusts may not be
fully invested on the next business day. The New Trust will contain a
portfolio of common stocks of diversified within a specific industry sector.
Rollover Unitholders will receive the amount of dividends in the Income
Account which will be included in the reinvestment in units of the New Trust.

Risk Factors. An investment in Units should be made with an understanding of
the risks associated therewith, including the possible deterioration of the
financial condition of the issuers, the general condition of the stock market
and stock price volatility. An investment should also be made with an
understanding of the special risks related to companies concentrated within a
single industry sector. For certain risk considerations related to the Trusts,
see "Risk Factors" .

<FN>
<F1>As of the close of business on any day on which the Sponsor is the sole
Unitholder of a Trust, the number of Units may be adjusted so that the Public
Offering Price per Unit will equal approximately $10. Therefore, to the extent
of any such adjustment the fractional undivided interest per Unit will
increase or decrease from the amount indicated above.

<F2>Each Security listed on a national securities exchange is valued at the
closing sale price or if the Security is not so listed, at the asked price
thereof.

<F3>The Sales Charge consists of an initial sales charge and a deferred sales
charge. The initial sales charge is applicable to all Units and represents an
amount equal to the difference between the total sales charge (3.25% of the
Public Offering Price) and the amount of the deferred sales charge ($0.225 per
Unit). Unitholders will also be subject to a deferred sales charge equal to
$0.225 per Unit. Subsequent to the Initial Date of Deposit, the amount of the
initial sales charge will vary with changes in the aggregate value of the
Securities. Units purchased subsequent to the initial deferred sales charge
payment will be subject only to that portion of the deferred sales charge
payments not yet collected. These deferred sales charge payments will be paid
from funds in the Capital Account, if sufficient, or from the periodic sale of
Securities. See the "Fee Table" below and "Public
Offering--General" . 

<F4>On the Initial Date of Deposit there will be no cash in the Income or Capital
Accounts. Anyone ordering Units after such date will have included in the
Public Offering Price a pro rata share of any cash in such Accounts. 

<F5>The Redemption Price per Unit and the Initial Secondary Market Repurchase
Price per Unit are reduced by the unpaid portion of the deferred sales charge.

<F6>Estimated annual dividends are based on annualizing the most recently declared
dividends. Estimated Annual Dividends per Unit are based on the number of
Units, the fractional undivided interest in the Securities per Unit and the
aggregate value of the Securities per Unit as of the Initial Date of Deposit.
Investors should note that the actual annual dividends received per Unit will
vary from the estimated amount due to changes in the factors described in the
preceding sentence and actual dividends declared and paid by the issuers of
the Securities.

<F7>Each Trust (and therefore Unitholders) will bear all or a portion of its
organizational costs (including costs of preparing the registration statement,
the trust indenture and other closing documents, registering Units with the
Securities and Exchange Commission and states, the initial audit of the Trust
portfolio and the initial fees and expenses of the Trustee but not including
the expenses incurred in the preparation and printing of brochures and other
advertising materials and any other selling expenses) as is common for mutual
funds. Total organizational expenses will be amortized over two years and paid
from funds in the Capital Account, if sufficient, or from the sale of
Securities. See "Trust Operating Expenses" and "Statements of
Condition" . 

<F8>No distribution will be made unless the amount available for distribution in
the Income and Capital Accounts equals at least $0.01 per Unit.
</TABLE>

FEE TABLE    

This Fee Table is intended to assist investors in understanding the costs and
expenses that an investor will bear directly or indirectly. See  "Public
Offering--General" and "Trust Operating Expenses" . Although each Trust has a
fixed two year term, and is a unit investment trust  rather than a mutual fund,
this information is presented to permit a comparison of fees. The example below
assumes that the principal  amount of and distributions on an investment are
rolled over into a new Series of the Trust at termination subject only to the
anticipated  reduced sales charge applicable to Rollover Unitholders. See "Right
of Unitholders--Special Redemption and Rollover in New Trust." Investors should
note that while this example is based on the public offering price and the
estimated fees for the current Trusts, the actual  public offering price and
fees for any new trusts created in the future periods indicated could vary from
those of the current Trusts.

An investor would pay the following expenses on a $1,000 investment, assuming a

</TABLE>

The example assumes reinvestment of all dividends and distributions at the end
of each year and utilizes a 5% annual rate of return as mandated by Securities
and Exchange Commission regulations applicable to mutual funds. For purposes
of the example, the deferred sales charge imposed on reinvestment of dividends
is not reflected until the year following payment of the dividend; the
cumulative expenses would be higher if sales charges on reinvested dividends
were reflected in the year of reinvestment. The example should not be
considered representations of past or future expenses or annual rate of
return; the actual expenses and annual rate of return may be more or less than
those assumed for purposes of the example. 

- ----------
The Initial Sales Charge is actually the difference between the Total Sales
Charge (3.25% of the Public Offering Price) and the Deferred Sales Charges
($0.225 per Unit) and would exceed 1.00% if the Public Offering Price exceeds
$10 per Unit.

The actual deferred sales charge is $0.225 per Unit, irrespective of purchase
or redemption price, deducted over eight months. If a Unitholder sells or
redeems Units before all of the deferred sales charge payments have been
deducted, the balance of the remaining payments will be deducted from the
sales or redemption proceeds. If Unit price exceeds $10 per Unit, the deferred
portion of the sales charge will be less than 2.25%; if Unit price is less
than $10 per Unit, the deferred portion of the sales charge will exceed 2.25%.
Units purchased subsequent to the initial deferred sales charge payment will
be subject to only that portion of the deferred sales charge payments not yet
collected. 

Reinvested dividends will be subject only to the deferred sales charge
remaining at the time of reinvestment. See "Rights of
Unitholders--Reinvestment Option" .

THE TRUSTS

- --------------------------------------------------------------------------
Van Kampen American Capital Equity Opportunity Trust, Series 90 is comprised
of two underlying separate unit investment trusts designated as Internet
Trust, Series 9, Telecommunications Trust, Series 1, Health Care &
Pharmaceuticals Trust, Series 1 and Utility Trust, Series 1. The Fund was
created under the laws of the State of New York pursuant to a Trust Indenture
and Trust Agreement (the "Trust Agreement" ), dated the date of this
Prospectus (the "Initial Date of Deposit" ), among Van Kampen American
Capital Distributors, Inc., as Sponsor, Van Kampen American Capital Investment
Advisory Corp., as Supervisor, The Bank of New York, as Trustee, and American
Portfolio Evaluation Services, a division of Van Kampen American Capital
Investment Advisory Corp., as Evaluator. 

The Trusts offer investors the opportunity to purchase Units representing
proportionate interests in separate portfolios of actively traded equity
securities issued by companies within a specific industry sector.
Diversification of assets in a Trust will not eliminate the risk of loss
always inherent in the ownership of securities.

On the Initial Date of Deposit, the Sponsor deposited with the Trustee the
Securities indicated under "Portfolio" herein, including delivery
statements relating to contracts for the purchase of certain such Securities
and an irrevocable letter of credit issued by a financial institution in the
amount required for such purchases. Thereafter, the Trustee, in exchange for
such Securities (and contracts) so deposited, delivered to the Sponsor
documentation evidencing the ownership of that number of Units indicated in
"Summary of Essential Financial Information" . Unless terminated
earlier, each Trust will terminate on the Mandatory Termination Date set forth
under "Summary of Essential Financial Information" and any Securities
then held will, within a reasonable time thereafter, be liquidated or
distributed by the Trustee. Any Securities liquidated at termination will be
sold at the then current market value for such Securities; therefore, the
amount distributable in cash to a Unitholder upon termination may be more or
less than the amount such Unitholder paid for his Units. Upon the Rollover
Notification Date, Unitholders may choose to reinvest their proceeds into a
subsequent trust, if available, at a reduced sales charge, to receive a pro
rata distribution of the Securities then included in a Trust (if they own the
requisite minimum number of Units) or to receive a cash distribution.

Additional Units of a Trust may be issued at any time by depositing in the
Trust (i) additional Securities, (ii) contracts to purchase securities
together with cash or irrevocable letters of credit or (iii) cash (or a letter
of credit) with instructions to purchase additional Securities. As additional
Units are issued by a Trust as a result of the deposit of additional
Securities, the aggregate value of the Securities in the Trust will be
increased and the fractional undivided interest in the Trust represented by
each Unit will be decreased. The Sponsor may continue to make additional
deposits of Securities or cash with instructions to purchase Securities into a
Trust following the Initial Date of Deposit, provided that such additional
deposits will be in amounts which will maintain, as nearly as practicable, the
same percentage relationship among the number of shares of each Equity
Security in the Trust's portfolio that existed immediately prior to any such
subsequent deposit. Any deposit of additional Equity Securities will
duplicate, as nearly as is practicable, this actual proportionate relationship
and not the original proportionate relationship on the Initial Date of
Deposit, since the actual proportionate relationship may be different than the
original proportionate relationship. Any such difference may be due to the
sale, redemption or liquidation of any of the Equity Securities. Existing and
new investors may experience a dilution of their investments and a reduction
in their anticipated income as a result of an additional deposit because of
fluctuations in the prices of the Securities between the time of the deposit
and the purchase of the Securities and because the Trusts will pay the
associated brokerage fees.

Each Unit initially offered represents an undivided interest in the related
Trust. To the extent that any Units are redeemed by the Trustee or additional
Units are issued as a result of additional Securities being deposited by the
Sponsor, the fractional undivided interest in a Trust represented by each
unredeemed Unit will increase or decrease accordingly, although the actual
interest in the Trust represented by such fraction will remain unchanged.
Units will remain outstanding until redeemed upon tender to the Trustee by
Unitholders, which may include the Sponsor, or until the termination of the
Trust Agreement. 

OBJECTIVES AND SECURITIES SELECTION 

- --------------------------------------------------------------------------
Internet Trust. This Trust seeks capital appreciation by investing in a
portfolio of common stocks of companies primarily involved in either the
enabling technology or communications services areas of the Internet. In
selecting these Securities, the Sponsor considered companies engaged in one or
more of the following areas:  manufacturers or providers of enabling
technology, access equipment, communications equipment,s ervice providers,
access and value-added services, and commerce and value-added services,
software and network services. As with any investment, there is no guarantee
that the Trust will achieve its objective.

Telecommunications Trust, Series 1. This Trust seeks capital appreciation by
investing in a portfolio of common stocks of companies diversified within the
telecommunications industry. In selecting these Securities, the Sponsor
considered _____. As with any investment, there is no guarantee that the Trust
will achieve its objective. The following is a general description of the
companies included in the Trust.

Health Care & Pharmaceuticals Trust, Series 1. This Trust seeks capital
appreciation by investing in a portfolio of common stocks of companies
diversified within the health care and pharmaceuticals industry. In selecting
these Securities, the Sponsor considered _____. As with any investment, there
is no guarantee that the Trust will achieve its objective. The following is a
general description of the companies included in the Trust.

Utility Trust, Series 1. This Trust seeks capital appreciation by investing in
a portfolio of common stocks of companies diversified within the utility
industry. In selecting these Securities, the Sponsor considered _____. As with
any investment, there is no guarantee that the Trust will achieve its
objective. The following is a general description of the companies included in
the Trust.

General. Investors will be subject to taxation on the dividend income, if any,
received by a Trust and on gains from the sale or liquidation of Securities.
Investors should be aware that there is not any guarantee that the objective
of a Trust will be achieved because it is subject to the continuing ability of
the respective issuers to declare and pay dividends and because the market
value of the Securities can be affected by a variety of factors. Common stocks
may be especially susceptible to general stock market movements and to
volatile increases and decreases of value as market confidence in and
perceptions of the issuers change. Investors should be aware that there can be
no assurance that the value of the underlying Securities will increase or that
the issuers of the Securities, which are primarily aggressive growth
companies, will pay dividends on outstanding common shares. Any distribution
of income will generally depend upon the declaration of dividends by the
issuers of the Securities and the declaration of any dividends depends upon
several factors including the financial condition of the issuers and general
economic conditions. See "Risk Factors" .

Investors should be aware that the Trusts are not "managed" funds and
as a result the adverse financial condition of a company will not result in
its elimination from a portfolio except under extraordinary circumstances (see
"Trust Administration--Portfolio Administration" ). In addition,
Securities will not be sold by the Trusts to take advantage of market
fluctuations or changes in anticipated rates of appreciation. Investors should
note in particular that the Securities were selected for inclusion in each
Trust as of the Initial Date of Deposit. Subsequent to the Initial Date of
Deposit, the Securities may no longer meet the criteria necessary for
inclusion on the Initial Date of Deposit. Should a Security fail to meet such
criteria following the Initial Date of Deposit, such Security will not as a
result thereof be removed from a portfolio. In addition, since the Sponsor may
deposit additional Equity Securities which were originally selected through
this process, the Sponsor may continue to sell Units even though the Equity
Securities would no longer be chosen for deposit into the Trusts if the
selection process were to be made again at a later time. Because certain of
the Equity Securities from time to time may be sold under certain
circumstances described herein, and because the proceeds from such events will
in most cases be distributed to Unitholders and will not be reinvested, no
assurance can be given that a Trust will retain for any length of time its
present size and composition. Although the portfolios are not managed, the
Sponsor may instruct the Trustee to sell Equity Securities under certain
limited circumstances. See "Trust Administration--Portfolio
Administration." 

TRUST PORTFOLIOS

- --------------------------------------------------------------------------
Each Trust consists of a diversified portfolio of common stocks issued by
companies within its related industry sector. All of the Securities are listed
on a national securities exchange, the NASDAQ National Market System or are
traded in the over-the-counter market. A general description of the issuers in
a each Trust is listed below.

Internet Trust

[descriptions to come]

Telecommunications Trust

[descriptions to come]

Health Care & Pharmaceuticals Trust

[descriptions to come]

Utility Trust

[descriptions to come]

General. Each Trust consists of (a) the Equity Securities (including contracts
for the purchase thereof) listed under "Portfolio" as may continue to
be held from time to time in the Trust, (b) any additional Equity Securities
acquired and held by the Trust pursuant to the provisions of the Trust
Agreement and (c) any cash held in the Income and Capital Accounts. Neither
the Sponsor nor the Trustee shall be liable in any way for any failure in any
of the Equity Securities. However, should any contract for the purchase of any
of the Equity Securities initially deposited hereunder fail, the Sponsor will,
unless substantially all of the moneys held in a Trust to cover such purchase
are reinvested in substitute Equity Securities in accordance with the Trust
Agreement, refund the cash and sales charge attributable to such failed
contract to all Unitholders on or before the next scheduled distribution date. 

RISK FACTORS 

- --------------------------------------------------------------------------
General. An investment in Units should be made with an understanding of the
risks which an investment in common stocks entails, including the risk that
the financial condition of the issuers of the Equity Securities or the general
condition of the common stock market may worsen and the value of the Equity
Securities and therefore the value of the Units may decline. Common stocks are
especially susceptible to general stock market movements and to volatile
increases and decreases of value as market confidence in and perceptions of
the issuers change. These perceptions are based on unpredictable factors
including expectations regarding government, economic, monetary and fiscal
policies, inflation and interest rates, economic expansion or contraction, and
global or regional political, economic or banking crises. Shareholders of
common stocks have rights to receive payments from the issuers of those common
stocks that are generally subordinate to those of creditors of, or holders of
debt obligations or preferred stocks of, such issuers. Shareholders of common
stocks of the type held by the Trusts have a right to receive dividends only
when and if, and in the amounts, declared by each issuer's board of directors
and have a right to participate in amounts available for distribution by such
issuer only after all other claims on such issuer have been paid or provided
for. Common stocks do not represent an obligation of the issuer and,
therefore, do not offer any assurance of income or provide the same degree of
protection of capital as do debt securities. The issuance of additional debt
securities or preferred stock will create prior claims for payment of
principal, interest and dividends which could adversely affect the ability and
inclination of the issuer to declare or pay dividends on its common stock or
the rights of holders of common stock with respect to assets of the issuer
upon liquidation or bankruptcy. The value of common stocks is subject to
market fluctuations for as long as the common stocks remain outstanding, and
thus the value of the Equity Securities in a portfolio may be expected to
fluctuate over the life of the Trusts to values higher or lower than those
prevailing on the Initial Date of Deposit.

Holders of common stocks incur more risk than holders of preferred stocks and
debt obligations because common stockholders, as owners of the entity, have
generally inferior rights to receive payments from the issuer in comparison
with the rights of creditors of, or holders of debt obligations or preferred
stocks issued by, the issuer. Cumulative preferred stock dividends must be
paid before common stock dividends and any cumulative preferred stock dividend
omitted is added to future dividends payable to the holders of cumulative
preferred stock. Preferred stockholders are also generally entitled to rights
on liquidation which are senior to those of common stockholders.

Whether or not the Equity Securities are listed on a national securities
exchange, the principal trading market for the Equity Securities may be in the
over-the-counter market. As a result, the existence of a liquid trading market
for the Equity Securities may depend on whether dealers will make a market in
the Equity Securities. There can be no assurance that a market will be made
for any of the Equity Securities, that any market for the Equity Securities
will be maintained or of the liquidity of the Equity Securities in any markets
made. In addition, the Trusts may be restricted under the Investment Company
Act of 1940 from selling Equity Securities to the Sponsor. The price at which
the Equity Securities may be sold to meet redemptions, and the value of the
Trusts, will be adversely affected if trading markets for the Equity
Securities are limited or absent.

The Trust Agreement authorizes the Sponsor to increase the size of each Trust
and the number of Units thereof by the deposit of additional Securities, or
cash (or a letter of credit) with instructions to purchase additional
Securities, in the Trust and issuance of a corresponding number of additional
Units. If the Sponsor deposits cash, existing and new investors may experience
a dilution of their investments and reduction in their anticipated income
because of fluctuations in the prices of the Securities between the time of
the cash deposit and the purchase of the Securities and because the Trusts
will pay the associated brokerage fees.

As described under "Trust Operating Expenses," all of the expenses of
the Trusts will be paid from the sale of Securities. It is expected that such
sales will be made at the end of the initial offering period and each month
thereafter through termination of the Trusts. Such sales will result in
capital gains and losses and may be made at times and prices which adversely
affect the Trusts. For a discussion of the tax consequences of such sales, see
"Federal Taxation." 

Unitholders will be unable to dispose of any of the Equity Securities, as
such, and will not be able to vote the Equity Securities. As the holder of the
Equity Securities, the Trustee will have the right to vote all of the voting
stocks in the Trusts and will vote such stocks in accordance with the
instructions of the Sponsor. In the absence of any such instructions by the
Sponsor, the Trustee will vote such stocks so as to insure that the stocks are
voted as closely as possible in the same manner and the same general
proportion as are shares held by owners other than the Trusts.

Like other investment companies, financial and business organizations and
individuals around the world, the Trusts could be adversely affected if the
computer systems used by the Sponsor, Evaluator, Supervisor or Trustee or
other service providers to the Trusts do not properly process and calculate
date-related information and data from and after January 1, 2000. This is
commonly known as the "Year 2000 Problem." The Sponsor, Evaluator,
Supervisor and Trustee are taking steps that they believe are reasonably
designed to address the Year 2000 Problem with respect to computer systems
that they use and to obtain reasonable assurances that comparable steps are
being taken by the Trusts' other service providers. At this time, however,
there can be no assurance that these steps will be sufficient to avoid any
adverse impact to the Trusts. The Year 2000 Problem is expected to impact
corporations, which may include issuers of the Securities, to varying degrees
based upon various factors, including, but not limited to, their industry
sector and degree of technological sophistication. The Sponsor is unable to
predict what impact, if any, the Year 2000 Problem will have no issuers of the
Securities.

Internet-Related Technology Companies. The Internet Trust is concentrated in
issuers within the technology industry. A portfolio concentrated in a single
industry may present more risk than a portfolio broadly diversified over
several industries. The Internet Trust, and therefore Unitholders, may be
particularly susceptible to a negative impact resulting from adverse market
conditions or other factors affecting technology issuers because any negative
impact on the technology industry will not be diversified among issuers within
other unrelated industries. Accordingly, an investment in Units of the
Internet Trust should be made with an understanding of the characteristics of
the technology industry and the risk which such an investment may entail.

Technology companies generally include companies involved in the development,
design, manufacture and sale of computers, computer related equipment,
computer networks, communications systems, telecommunications products,
electronic products, and other related products, systems and services. The
market for technology products and services, especially those specifically
related to the Internet, is characterized by rapidly changing technology,
rapid product obsolenscense, cyclical market patters, evolving industry
standards and frequent new product introductions. The success of the issuers
of the Securities depends in substantial part of the timely and successful
introduction of new products. An unexpected change in one or more of the
technologies affecting an issuer's products or in the market for products
based on a particular technology could have a material adverse affect on an
issuer's operating results. Furthermore, there can be no assurance that the
issuers of the Securities will be able to respond timely to compete in the
rapidly development marketplace or that the Internet will continue to be
accepted as a means of communication and commerce.

The market for Internet-related products and services has only recently begun
to develop, is rapidly evolving and is characterized by an increasing number
of market entrants who have introduced or developed products and services for
communication and commerce over the Internet. The industry is young and has
few proven products and services. Moreover, critical issues concerning the
commercial use of the Internet (including security, cost, ease of use and
access, and quality of service) remain unresolved and may impact the growth of
Internet use. Additionally, many Internet-related companies have only recently
commenced operations or offered substantial number of the issues included in
the Internet Trust occurred only within the last two years. Such companies are
in the early stage of development and have a limited operating history on
which to analyze future operating results. Such securities are generally
regarded as speculative investments. It is important to note that following
its initial public offering a security is likely to experience substantial
stock price volatility and speculative trading.  Accordingly, there can be no
assurance that upon redemption of Units or termination of the Internet Trust a
Unitholder will receive an amount greater than or equal to the Unitholder's
initial investment.

There can be no assurance that commerce and communication over the Internet
will become widespread or that any related products or services will become
widely adopted for these purposes. If the market fails to develop, develops
more slowly than expected, becomes saturated with competitors or certain
products or services do not achieve market acceptance, the financial condition
of the issuers of the Securities could be materially adversely affected. In
addition, due to the increasing use of the Internet, it is possible that
various laws and regulations may be adopted addressing issues such as privacy,
pricing, characteristics, and quality of Internet products and services. For
example, recent proposals would prohibit distribution of obscene, lascivious
or indecent communications on the Internet. The adoption of any such laws
could have a material adverse impact on the Securities in the Internet Trust.

Based on trading history, factors such as announcements of new products or
development of new technologies and genral conditions of the industry have
caused and are likely to cause the market price of technology common stocks to
fluctuate substantially. In addition, technology company stocks have
experienced extreme price and volume fluctuations that often have been
unrelated to the operating performance of such companies. This market
volatility may adversely affect the market price of the Securities and
therefore the ability of a Unitholder to redeem Units, or roll over Units into
a new trust, at a price equal to or greater than the original price paid for
such Units.

Some key components of certain products of technology issuers are currently
available only from single sources. There can be no assurance that in the
future suppliers will be able to meet the demand for components in a timely
and cost effective manner. Accordingly, an issuer's operating results and
customer relationships could be adversely affected by either an increase in
price for, or an interruption or reduction in supply of, any key components.
Additionally, many technology issuers are characterized by a highly
concentrated customer base consisting of a limited number of large customers
who may require product vendors to comply with rigorous and constantly
developing industry standards. Any failure to comply with such standards may
result in a significant loss or reduction of sales. Because many products and
technologies of Internet-related companies are incorporated into other related
products, such companies are often highly dependent on the performance of
other computer, electronics and communications companies (many of which are
included in the Internet Trust's portfolio). There can be no assurance that
these customers will place additional orders, or that an issuer of Securities
will obtain orders of similar magnitude as past orders from other customers.
Similarly, the success of many Internet-related companies is tied to a
relatively small concentration of products or technologies with intense
competition between companies. Accordingly, a decline in demand of such
products, technologies or from such customers could have a material adverse
impact on issuers of the Securities.

Certain issuers of the Securities derived a significant amount of business in
foreign markets. Many countries, especially emerging market countries, have
regulatory requirements that differ from U.S. requirements are characterized
by less developed and more volatile economies. International sales and
operations are subject to certain risks, including unexpected changes in
regulatory environments, exchange rates, tariffs and other barriers, political
and economic instability and potentially adverse tax consequences. All of
these factors could have a material adverse impact on the financial condition
of certain issuers.

Many technology companies rely on a combination of patents, copyrights,
trademarks and trade secret laws to establish and protect their proprietary
rights in their products and technologies. There can be no assurance that the
steps taken by the issuers of the Securities to protect their proprietary
rights will be adequate to prevent misappropriation of their technology or
that competitors will nto independently develop technologies that are
substanially equivalent or superior to such issuers' technology.

FEDERAL TAXATION

- --------------------------------------------------------------------------
General. The following is a general discussion of certain of the Federal
income tax consequences of the purchase, ownership and disposition of the
Units. The summary is limited to investors who hold the Units as capital
assets (generally, property held for investment) within the meaning of Section
1221 of the Internal Revenue Code of 1986 (the "Code" ). Unitholders
should consult their tax advisers in determining the federal, state, local and
any other tax consequences of the purchase, ownership and disposition of Units
in the Trust. For purposes of the following discussion and opinion, it is
assumed that each Security is equity for Federal income tax purposes.

In the opinion of Chapman and Cutler, special counsel for the Sponsor, under
existing law:

1. The Trust is not an association taxable as a corporation for Federal income
tax purposes; each Unitholder will be treated as the owner of a pro rata
portion of each of the assets of the Trust under the Code; and the income of
the Trust will be treated as income of the Unitholders thereof under the Code.
Each Unitholder will be considered to have received his pro rata share of
income derived from each Trust asset when such income is considered to be
received by the Trust.

2. A Unitholder will be considered to have received all of the dividends paid
on his pro rata portion of each Security when such dividends are considered to
be received by the Trust regardless of whether such dividends are used to pay
a portion of the deferred sales charge. Unitholders will be taxed in this
manner regardless of whether distributions from the Trust are actually
received by the Unitholder or are automatically reinvested (see "Rights of
Unitholders--Reinvestment Option" ).

3. Each Unitholder will have a taxable event when the Trust disposes of a
Security (whether by sale, exchange, liquidation, redemption, or otherwise) or
upon the sale or redemption of Units by such Unitholder (except to the extent
an in kind distribution of stock is received by such Unitholder as described
below). The price a Unitholder pays for his Units, generally including sales
charges, is allocated among his pro rata portion of each Security held by the
Trust (in proportion to the fair market values thereof on the valuation date
nearest to the date the Unitholder purchases his Units) in order to determine
his tax basis for his pro rata portion of each Security held by the Trust. It
should be noted that certain legislative proposals have been made which could
affect the calculation of basis for Unitholders holding securities that are
substantially identical to the Securities. Unitholders should consult their
own tax advisors with regard to calculation of basis. For Federal income tax
purposes, a Unitholder's pro rata portion of dividends as defined by Section
316 of the Code paid by a corporation with respect to a Security held by the
Trust is taxable as ordinary income to the extent of such corporation's
current and accumulated "earnings and profits" . A Unitholder's pro
rata portion of dividends paid on such Security which exceeds such current and
accumulated earnings and profits will first reduce a Unitholder's tax basis in
such Security, and to the extent that such dividends exceed a Unitholder's tax
basis in such Security shall generally be treated as capital gain. In general,
the holding period for such capital gain will be determined by the period of
time a Unitholder has held his Units.

4. A Unitholder's portion of gain, if any, upon the sale or redemption of
Units or the disposition of Securities held by the Trust will generally be
considered a capital gain (except in the case of a dealer or a financial
institution). A Unitholder's portion of loss, if any, upon the sale or
redemption of Units or the disposition of Securities held by the Trust will
generally be considered a capital loss (except in the case of a dealer or a
financial institution). Unitholders should consult their tax advisers
regarding the recognition of gains and losses for Federal income tax purposes.
In particular, a Rollover Unitholder should be aware that a Rollover
Unitholder's loss, if any, incurred in connection with the exchange of Units
for units in the next new trust (the "New Trust" ) will generally be
disallowed with respect to the disposition of any Securities pursuant to such
exchange to the extent that such Unitholder is considered the owner of
substantially identical securities under the wash sale provisions of the Code
taking into account such Unitholder's deemed ownership of the securities
underlying the Units in the New Trust in the manner described above, if such
substantially identical securities were acquired within a period beginning 30
days before and ending 30 days after such disposition. However, any gains
incurred in connection with such an exchange by a Rollover Unitholder would be
recognized. Unitholders should consult their tax advisers regarding the
recognition of gains and losses for Federal income tax purposes.

Deferred Sales Charge. Generally, the tax basis of a Unitholder includes sales
charges, and such charges are not deductible. A portion of the sales charge
for the Trust is deferred. The income (or proceeds from redemption) a
Unitholder must take into account for Federal income tax purposes is not
reduced by amounts deducted to pay the deferred sales charge. Unitholders
should consult their own tax advisers as to the income tax consequences of the
deferred sales charge.

Dividends Received Deduction. A corporation that owns Units will generally be
entitled to a 70% dividends received deduction with respect to such
Unitholder's pro rata portion of dividends received by the Trust (to the
extent such dividends are taxable as ordinary income, as discussed above, and
are attributable to domestic corporations) in the same manner as if such
corporation directly owned the Securities paying such dividends (other than
corporate Unitholders, such as "S" corporations, which are not
eligible for the deduction because of their special characteristics and other
than for purposes of special taxes such as the accumulated earnings tax and
the personal holding corporation tax). However, a corporation owning Units
should be aware that Sections 246 and 246A of the Code impose additional
limitations on the eligibility of dividends for the 70% dividends received
deduction. These limitations include a requirement that stock (and therefore
Units) must generally be held at least 46 days (as determined under Section
246(c) of the Code). Final regulations have been issued which address special
rules that must be considered in determining whether the 46 day holding period
requirement is met. Moreover, the allowable percentage of the deduction will
be reduced from 70% if a corporate Unitholder owns certain stock (or Units)
the financing of which is directly attributable to indebtedness incurred by
such corporation. It should be noted that various legislative proposals that
would affect the dividends received deduction have been introduced.
Unitholders should consult with their tax advisers with respect to the
limitations on and possible modifications to the dividends received deduction.

To the extent dividends received by the Trust are attributable to foreign
corporations, a corporation that owns Units will not be entitled to the
dividends received deduction with respect to its pro rata portion of such
dividends, since the dividends received deduction is generally available only
with respect to dividends paid by domestic corporations.

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. Unitholders may be required to treat some or all of the expenses
of the Trust as miscellaneous itemized deductions subject to this limitation.

Recognition of Taxable Gain or Loss Upon Disposition of Securities by the
Trust or Disposition of Units. As discussed above, a Unitholder may recognize
taxable gain (or loss) when a Security is disposed of by the Trust or if the
Unitholder disposes of a Unit (although losses incurred by Rollover
Unitholders may be subject to disallowance, as discussed above). 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) is subject
to a maximum marginal stated tax rate of either 28% or 20%, depending upon the
holding periods of the capital assets. Capital 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. Generally, capital gains
realized from assets held for more than one year but not more than 18 months
are taxed at a maximum marginal stated tax rate of 28% and capital gains
realized from assets (with certain exclusions) held for more than 18 months
are taxed at a maximum marginal stated tax rate of 20% (10% in the case of
certain taxpayers in the lowest tax bracket). Further, capital gains realized
from assets held for one year or less are taxed ar the same rates as ordinary
income. Legislation is currently pending that provides the appropriate
methodology that should be applied in netting the realized capital gains and
losses. Such legislation is proposed to be effective retroactively for tax
years ending after May 6, 1997. Note that the date on which a Unit is acquired
(i.e., the "trade date" ) is excluded for purposes of determining the
holding period of the Unit. It should be noted that legislative proposals are
introduced from time to time that affect tax rates and could affect relative
differences at which ordinary income and capital gains are taxed.

In addition, please note that capital gains may be recharacterized as ordinary
income in the case of certain financial transactions that are considered "
conversion transactions" effective for transactions entered into after
April 30, 1993. Unitholders and prospective investors should consult with
their tax advisers regarding the potential effect of this provision on their
investment in Units.

If a Unitholder disposes of a Unit he or she is deemed thereby to have
disposed of his entire pro rata interest in all the assets of the Trust
including his pro rata portion of all Securities represented by a Unit. The
Taxpayer Relief Act of 1997 (the "1997 Tax 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. Unitholders should consult their
own tax advisors with regard to any such constructive sale rules.

Special Tax Consequences of In Kind Distributions Upon Redemption of Units or
Termination of the Trust. As discussed in "Rights of
Unitholders--Redemption of Units," under certain circumstances a
Unitholder tendering Units for redemption may request an In Kind Distribution.
A Unitholder may also under certain circumstances request an In Kind
Distribution upon the termination of the Trust. See "Rights of
Unitholders--Redemption of Units" . The Unitholder requesting an In Kind
Distribution will be liable for expenses related thereto (the "
Distribution Expenses" ) and the amount of such In Kind Distribution will
be reduced by the amount of the Distribution Expenses. See "Rights of
Unitholders--Redemption of Units" . As previously discussed, prior to the
redemption of Units or the termination of the Trust, a Unitholder is
considered as owning a pro rata portion of each of the Trust's assets for
federal income tax purposes. The receipt of an In Kind Distribution will
result in a Unitholder receiving an undivided interest in whole shares of
stock plus, possibly, cash.

The potential tax consequences that may occur under an In Kind Distribution
with respect to each Security owned by the Trust will depend on whether or not
a Unitholder receives cash in addition to Securities. A "Security" for
this purpose is a particular class of stock issued by a particular
corporation. A Unitholder will not recognize gain or loss if a Unitholder only
receives Securities in exchange for his or her pro rata portion of the
Securities held by the Trust. However, if a Unitholder also receives cash in
exchange for a fractional share of a Security held by the Trust, such
Unitholder will generally recognize gain or loss based upon the difference
between the amount of cash received by the Unitholder and his tax basis in
such fractional share of a Security held by the Trust.

Because the Trust will own many Securities, a Unitholder who requests an In
Kind Distribution will have to analyze the tax consequences with respect to
each Security owned by the Trust. The amount of taxable gain (or loss)
recognized upon such exchange will generally equal the sum of the gain (or
loss) recognized under the rules described above by such Unitholder with
respect to each Security owned by the Trust. Unitholders who request an In
Kind Distribution are advised to consult their tax advisers in this regard. 

As discussed in "Rights of Unitholders--Special Redemption and Rollover in
New Trust," a Unitholder may elect to become a Rollover Unitholder. To the
extent a Rollover Unitholder exchanges his Units for Units of the New Trust in
a taxable transaction, such Unitholder will recognize gains, if any, but
generally will not be entitled to a deduction for any losses recognized upon
the disposition of any Securities pursuant to such exchange to the extent that
such Unitholder is considered the owner of substantially identical securities
under the wash sale provisions of the Code taking into account such
Unitholder's deemed ownership of the securities underlying the Units in the
New Trust in the manner described above, if such substantially identical
securities were acquired within a period beginning 30 days before and ending
30 days after such disposition under the wash sale provisions contained in
Section 1091 of the Code. In the event a loss is disallowed under the wash
sale provisions, special rules contained in Section 1091(d) of the Code apply
to determine the Unitholder's tax basis in the securities acquired. Rollover
Unitholders are advised to consult their tax advisers. 

Computation of the Unitholder's Tax Basis. Initially, a Unitholder's tax basis
in his Units will generally equal the price paid by such Unitholder for his
Units. The cost of the Units is allocated among the Securities held in the
Trust in accordance with the proportion of the fair market values of such
Securities on the valuation date nearest the date the Units are purchased in
order to determine such Unitholder's tax basis for his pro rata portion of
each Security.

A Unitholder's tax basis in his Units and his pro rata portion of a Security
held by the Trust will be reduced to the extent dividends paid with respect to
such Security are received by the Trust which are not taxable as ordinary
income as described above.

General. Each Unitholder will be requested to provide the Unitholder's
taxpayer identification number to the Trustee and to certify that the
Unitholder has not been notified by the Internal Revenue Service 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 Units) will be subject to back-up withholding.
Distributions by the Trust (other than those that are not treated as United
States source income, if any) will generally be subject to United States
income taxation and withholding in the case of Units held by non-resident
alien individuals, foreign corporations or other non-United States persons.
Such persons should consult their tax advisers.

In general, income that is not effectively connected to the conduct of a trade
or business within the United States that is earned by non-U.S. Unitholders
and derived from dividends of foreign corporations will not be subject to U.S.
withholding tax provided that less than 25 percent of the gross income of the
foreign corporation for a three-year period ending with the close of its
taxable year preceding payment was not effectively connected to the conduct of
a trade or business within the United States. In addition, such earnings may
be exempt from U.S. withholding pursuant to a specific treaty between the
United States and a foreign country. Non-U.S. Unitholders should consult their
own tax advisers regarding the imposition of U.S. withholding on distributions
from the Trust.

It should be noted that payments to the Trust of dividends on Equity
Securities that are attributable to foreign corporations may be subject to
foreign withholding taxes and Unitholders should consult their own tax
advisers regarding the potential tax consequences relating to the payment of
any such withholding taxes by the Trust. Any dividends withheld as a result
thereof will nevertheless be treated as income to the Unitholders. Because,
under the grantor trust rules, an investor is deemed to have paid directly his
share of foreign taxes that have been paid or accrued, if any, an investor may
be entitled to a foreign tax credit or deduction for United States purposes
with respect to such taxes. The 1997 Tax Act imposes a required holding period
for such credits. Investors should consult their tax advisers with respect to
foreign withholding taxes and foreign tax credits.

At the termination of the Trust, the Trustee will furnish to each Unitholder a
statement containing information relating to the dividends received by the
Trust on the Securities, the gross proceeds received by the Trust from the
disposition of any Security (resulting from redemption or the sale of any
Security), and the fees and expenses paid by the Trust. The Trustee will also
furnish annual information returns to Unitholders and to the Internal Revenue
Service.

Unitholders desiring to purchase Units for tax-deferred plans and IRAs should
consult their broker-dealers for details on establishing such accounts. Units
may also be purchased by persons who already have self-directed plans
established. 

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 the tax treatment of U.S. Unitholders
("U.S. Unitholders" ) with regard to federal and certain aspects of New
York State and City income taxes. Unitholders may be subject to taxation in
New York or in other jurisdictions and should consult their own tax advisers
in this regard. As used herein, the term "U.S. Unitholder" means an
owner of a Unit of the Trust that (a) is (i) for United States Federal income
tax purposes a citizen or resident of the United States, (ii) a corporation,
partnership or other entity created or organized in or under the laws of the
United States or of any political subdivision thereof, or (iii) an estate or
trust the income of which is subject to United States federal income taxation
regardless of its source or (b) does not qualify as a U.S. Unitholder in
paragraph (a) but whose income from a Unit is effectively connected with such
Unitholder's conduct of a United States trade or business. The term also
includes certain former citizens of the United States whose income and gain on
the Units will be taxable.

TRUST OPERATING EXPENSES 

- --------------------------------------------------------------------------
Compensation of Sponsor and Evaluator. The Sponsor will not receive any fees
in connection with its activities relating to the Trusts. However, Van Kampen
American Capital Investment Advisory Corp., which is an affiliate of the
Sponsor, will receive an annual supervisory fee which is not to exceed the
amount set forth under "Summary of Essential Financial Information" ,
for providing portfolio supervisory services for the Trusts. Such fee (which
is based on the number of Units outstanding on January 1 of each year except
during the initial offering period in which event the calculation is based on
the number of Units outstanding at the end of the month of such calculation)
may exceed the actual costs of providing such supervisory services for these
Trusts, but at no time will the total amount received for portfolio
supervisory services rendered to all unit investment trusts sponsored by the
Sponsor for which the Supervisor provides portfolio supervisory services in
any calendar year exceed the aggregate cost to the Supervisor of supplying
such services in such year. In addition, American Portfolio Evaluation
Services, which is a division of Van Kampen American Capital Investment
Advisory Corp., shall receive for regularly providing evaluation services to
the Trust the annual per Unit evaluation fee set forth under "Summary of
Essential Financial Information" (which is based on the number of Units
outstanding on January 1 of each year for which such compensation relates
except during the initial offering period in which event the calculation is
based on the number of Units outstanding at the end of the month of such
calculation) for regularly evaluating the Trust portfolios. The fees set forth
herein are payable as described under "General" below. Both of the
foregoing fees may be increased without approval of the Unitholders by amounts
not exceeding proportionate increases under the category "All Services
Less Rent of Shelter" in the Consumer Price Index published by the United
States Department of Labor or, if such category is no longer published, in a
comparable category. The Sponsor will receive sales commissions and may
realize other profits (or losses) in connection with the sale of Units and the
deposit of the Securities as described under "Public Offering--Sponsor and
Other Compensation" .

Trustee's Fee. For its services the Trustee will receive the annual per Unit
fee from the Trusts set forth under "Summary of Essential Financial
Information" (which is based on the number of Units outstanding at the end
of the month of such calculation until the end of the initial offering period
at which time such calculation is based on the number of Units outstanding on
such date). The fees set forth herein are payable as described under "
General" below. The Trustee benefits to the extent there are funds for
future distributions, payment of expenses and redemptions in the Capital and
Income Accounts since these Accounts are non-interest bearing to Unitholders
and the amounts earned by the Trustee are retained by the Trustee. Part of the
Trustee's compensation for its services to the Trusts is expected to result
from the use of these funds. Such fees may be increased without approval of
the Unitholders by amounts not exceeding proportionate increases under the
category "All Services Less Rent of Shelter" in the Consumer Price
Index published by the United States Department of Labor or, if such category
is no longer published, in a comparable category. For a discussion of the
services rendered by the Trustee pursuant to its obligations under the Trust
Agreement, see "Rights of Unitholders--Reports Provided" and "
Trust Administration" . 

Miscellaneous Expenses. Expenses incurred in establishing each Trust,
including the cost of the initial preparation of documents relating to the
Trust (including the Prospectus, Trust Agreement and closing documents),
federal and state registration fees, the initial fees and expenses of the
Trustee, legal and accounting expenses, payment of closing fees and any other
out-of-pocket expenses, will be paid by the Trust and amortized over two
years. The following additional charges are or may be incurred by a Trust: (a)
normal expenses (including the cost of mailing reports to Unitholders)
incurred in connection with the operation of the Trust, (b) fees of the
Trustee for extraordinary services, (c) expenses of the Trustee (including
legal and auditing expenses) and of counsel designated by the Sponsor, (d)
various governmental charges, (e) expenses and costs of any action taken by
the Trustee to protect the Trust and the rights and interests of Unitholders,
(f) indemnification of the Trustee for any loss, liability or expenses
incurred in the administration of the Trust without negligence, bad faith or
wilful misconduct on its part, (g) accrual of costs associated with
liquidating securities and (h) expenditures incurred in contacting Unitholders
upon termination of the Trust. The fees set forth herein are payable as
described under "General" below.

General. During the initial offering period of each Trust, all of the fees and
expenses of the Trust will accrue on a daily basis and will be charged to the
Trust, in arrears, at the end of the initial offering period. After the
initial offering period, all of the fees and expenses of a Trust will accrue
on a daily basis and will be charged to the Trust, in arrears, on a monthly
basis. The fees and expenses are payable out of the Capital Account. When such
fees and expenses are paid by or owing to the Trustee, they are secured by a
lien on the related Trust's portfolio. If the balance in the Capital Account
is insufficient to provide for amounts payable by a Trust, the Trustee has the
power to sell Equity Securities to pay such amounts. It is expected that the
balance in the Capital Account will be insufficient to provide for amounts
payable by the Trusts and that Equity Securities will be sold from the Trusts
to pay such amounts. These sales may result in capital gains or losses to
Unitholders. See "Federal Taxation" .

PUBLIC OFFERING 

- --------------------------------------------------------------------------
General. Units are offered at the Public Offering Price. During the initial
offering period and for secondary market transactions after the initial
offering period the Public Offering Price is based on the aggregate underlying
value of the Securities, the initial sales charge described below, and cash,
if any, in the Income and Capital Accounts. The initial sales charge is equal
to the difference between the total sales charge for a Trust (3.25% of the
Public Offering Price) and the deferred sales charge ($0.225 per Unit). The
monthly deferred sales charge will begin accruing on a daily basis on May
_____, 1998 and will continue to accrue through January _____, 2000. The
monthly deferred sales charge will be charged, in arrears, commencing June
_____, 1998 and will be charged on the _____ day of each month thereafter
through January _____, 2000. If any deferred sales charge payment date is not
a business day, the payment will be charged on the next business day.
Unitholders will be assessed only that portion of the deferred sales charge
accrued from the time they became Unitholders of record. Units purchased
subsequent to the initial deferred sales charge payment will be subject to
only that portion of the deferred sales charge payments not yet collected. The
deferred sales charges will be paid from funds in the Capital Account, if
sufficient, or from the periodic sale of Securities. The sales charge
applicable to quantity purchases is reduced on a graduated basis to any person
acquiring 10,000 or more Units as follows:

<TABLE>

*The breakpoint sales charges are also applied on a dollar basis utilizing a  
breakpoint equivalent in the above table of $10 per Unit and will be applied  
on whichever basis is more favorable to the investor. The breakpoints will be 
adjusted to take into consideration purchase orders stated in dollars which   
cannot be completely fulfilled due to the requirement that only whole Units   
be issued.                                                                    
</TABLE>

Any sales charge reduction will primarily be the responsibility of the selling
broker, dealer or agent. This reduced sales charge structure will apply on all
purchases by the same person from any one dealer of units of Van Kampen
American Capital-sponsored unit investment trusts which are being offered in
the initial offering period (a) on any one day (the "Initial Purchase
Date" ) or (b) on any day subsequent to the Initial Purchase Date if (1)
the units purchased are of a unit investment trust purchased on the Initial
Purchase Date, and (2) the person purchasing the units purchased a sufficient
amount of units on the Initial Purchase Date to qualify for a reduced sales
charge on such date. In the event units of more than one trust are purchased
on the Initial Purchase Date, the aggregate dollar amount of such purchases
will be used to determine whether purchasers are eligible for a reduced sales
charge. Such aggregate dollar amount will be divided by the public offering
price per unit (on the day preceding the date of purchase) of each respective
trust purchased to determine the total number of units which such amount could
have purchased of each individual trust. Purchasers must then consult the
applicable trust's prospectus to determine whether the total number of units
which could have been purchased of a specific trust would have qualified for a
reduced sales charge and, if so qualified, the amount of such reduction.
Assuming a purchased qualified for a sales charge reduction or reductions, to
determine the applicable sales charge reduction or reductions it is necessary
to accumulate all purchases made on the Initial Purchase Date and all
purchases made in accordance with (b) above. Units purchased in the name of
the spouse of a purchaser or in the name of a child of such purchaser ("
immediate family members" ) will be deemed for the purposes of calculating
the applicable sales charge to be additional purchases by the purchaser. The
reduced sales charges will also be applicable to a trustee or other fiduciary
purchasing securities for one or more trust estate or fiduciary accounts. 

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

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) of Van Kampen American Capital
Distributors, 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.

During the initial offering period of the Trusts, unitholders of unaffiliated
unit investment trusts having an investment objective similar to the
investment objective of the Trusts may utilize proceeds received upon
termination or upon redemption immediately preceding termination of such
unaffiliated trust to purchase Units of the Trusts at the Public Offering
Price per Unit less 1%.

During the initial offering period, unitholders of any Van Kampen American
Capital-sponsored unit investment trust may utilize their redemption or
termination proceeds to purchase Units of these Trusts at the Public Offering
Price per Unit less 1%.

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

As indicated above, the price of the Units was established by adding to the
determination of the aggregate underlying value of the Securities an amount
equal to the difference between the total sales charge of 3.25% of the Public
Offering Price and the deferred sales charge ($0.225 per Unit) and dividing
the sum so obtained by the number of Units outstanding. The Public Offering
Price per Unit shall include the proportionate share of any cash held in the
Income and Capital Accounts. Such price determination as of the close of the
relevant stock market on the day before the Initial Day of Deposit was made on
the basis of an evaluation of the Securities prepared by Interactive Data
Corporation, a firm regularly engaged in the business of evaluating, quoting
or appraising comparable securities. Thereafter, the Evaluator on each
business day will appraise or cause to be appraised the value of the
underlying Securities as of the Evaluation Time and will adjust the Public
Offering Price of the Units commensurate with such valuation. Such Public
Offering Price will be effective for all orders received prior to the
Evaluation Time on each such day. Orders received by the Trustee or Sponsor
for purchases, sales or redemptions after that time, or on a day which is not
a business day for a Trust, will be held until the next determination of
price. Unitholders who purchase Units subsequent to the Initial Date of
Deposit will pay an initial sales charge equal to the difference between the
total sales charge and the deferred sales charge ($0.225 per Unit) and will be
assessed a deferred sales charge of $0.225 per Unit as set forth in "
Public Offering--General" . Effective _____, 1999 the sales charge will be
2.75% and will not include deferred payments. The Sponsor currently does not
intend to maintain a secondary market after August _____, 1999. Effective
December 21, 1998, the secondary market sales charge will be 2.75%.

The aggregate underlying value of the Equity Securities during the initial
offering period is determined on each business day by the Evaluator in the
following manner: if the Equity Securities are listed on a national securities
exchange, this evaluation is generally based on the closing sale prices on
that exchange (unless it is determined that these prices are inappropriate as
a basis for valuation) or, if there is no closing sale price on that exchange,
at the closing ask prices. If the Equity Securities are not so listed or, if
so listed and the principal market therefore is other than on the exchange,
the evaluation shall generally be based on the current ask price on the
over-the-counter market (unless it is determined that these prices are
inappropriate as a basis for evaluation). If current ask prices are
unavailable, the evaluation is generally determined (a) on the basis of
current ask prices for comparable securities, (b) by appraising the value of
the Equity Securities on the ask side of the market or (c) by any combination
of the above.

In offering the Units to the public, neither the Sponsor nor any
broker-dealers are recommending any of the individual Securities in a Trust
but rather the entire pool of Securities, taken as a whole, which are
represented by the Units.

Unit Distribution. During the initial offering period, Units will be
distributed to the public by the Sponsor, broker-dealers and others at the
Public Offering Price. Upon the completion of the initial offering period,
Units repurchased in the secondary market, if any, may be offered by this
Prospectus at the secondary market Public Offering Price in the manner
described above.

The Sponsor intends to qualify the Units for sale in a number of states.
Brokers, dealers and others will be allowed a concession or agency commission
in connection with the distribution of Units during the initial offering
period as set forth in the following table. A portion of such concessions or
agency commissions represents amounts paid by the Sponsor to such brokers,
dealers and others out of its own assets as additional compensation.

*The breakpoint concessions, agency commissions or additional payments are    
also applied on a dollar basis utilizing a breakpoint equivalent in the above 
table of $10 per Unit and will be applied on whichever basis is more          
favorable to the investor. The breakpoints will be adjusted to take into      
consideration purchase orders stated in dollars which cannot be completely    
fulfilled due to the requirement that only whole Units be issued.             
</TABLE>

In addition to the amounts set forth above, any firm that distributes a total
of 500,000-999,999 Units of a Trust during the initial offering period will be
paid additional compensation by the Sponsor of $0.005 per Unit distributed; or
any firm that distributes a total of 1,000,000 - 1,999,999 Units of a Trust
during the initial offering period will be paid additional compensation by the
Sponsor of $0.01 per Unit distributed; or any firm that distributes a total of
2,000,000 - 2,999,999 Units of a Trust during the initial offering period will
be paid additional compensation by the Sponsor of $0.015 per Unit distributed;
or any firm that distributes a total of 3,000,000 or more Units of a Trust
during the initial offering period will be paid additional compensation by the
Sponsor of $.02 per Unit distributed. Such additional compensation will be
paid at the end of the initial offering period of a Trust.

Any discount provided to investors will be borne by the selling dealer or
agent as indicated under "General" above. For transactions involving
Rollover Unitholders, the total concession or agency commission will amount
to1.50% per Unit (or such lesser amount resulting from quantity sales
discounts). For all secondary transactions, the total concession or agency
commission will amount to 70% of the sales charge applicable to the
transaction. Notwithstanding anything to the contrary herein, the total of any
concessions, agency commissions and any additional compensation allowed or
paid to any broker, dealer or other distributor of Units with respect to any
individual transaction, shall in no case exceed the total sales charge
applicable to such transaction.

Certain commercial banks are making Units available to their customers on an
agency basis. A portion of the sales charge (equal to the agency commission
referred to above) is retained by or remitted to the banks. Under the
Glass-Steagall Act, banks are prohibited from underwriting Trust Units;
however, the Glass-Steagall Act does permit certain agency transactions and
the banking regulators have not indicated that these particular agency
transactions are not permitted under such Act. In addition, state securities
laws on this issue may differ from the interpretations of federal law
expressed herein and banks and financial institutions may be required to
register as dealers pursuant to state law. 

To facilitate the handling of transactions, sales of Units shall normally be
limited to transactions involving a minimum of 100 Units per Trust except as
stated herein. In connection with fully disclosed transactions with the
Sponsor, the minimum purchase requirement will be that number of Units set
forth in the contract between the Sponsor and the related broker or agent. The
Sponsor reserves the right to reject, in whole or in part, any order for the
purchase of Units and to change the amount of the concession or agency
commission to dealers and others from time to time.

Sponsor and Other Compensation. The Sponsor will receive a gross sales
commission equal to 3.25% of the Public Offering Price of the Units less any
reduced sales charge for purchases as described under "General" above.
Any such discount provided to investors will be borne by the selling dealer or
agent.

In addition, the Sponsor will realize a profit or will sustain a loss, as the
case may be, as a result of the difference between the price paid for the
Securities by the Sponsor and the cost of such Securities to the Trusts on the
Initial Date of Deposit as well as on subsequent deposits. See "Notes to
Portfolios" . The Sponsor has not participated as sole underwriter or as
manager or as a member of the underwriting syndicates or as an agent in a
private placement for any of the Securities. The Sponsor may further realize
additional profit or loss during the initial offering period as a result of
the possible fluctuations in the market value of the Securities after a date
of deposit, since all proceeds received from purchasers of Units.

Broker-dealers, banks and/or others may be 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 brokers, dealers, banks and/or others may be
eligible to win other nominal awards for certain sales efforts, or under which
the Sponsor will reallow to such brokers, dealers, banks and/or others that
sponsor sales contests or recognition programs conforming to criteria
established by the Sponsor or participate in sales programs 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 paid fees to qualifying entities for certain
services or activities which are primarily intended to result in sales of
Units of the Trusts. Such payments are made by the Sponsor out of its own
assets, and not out of assets of the Trusts. These programs will not change
the price Unitholders pay for their Units or the amount that the Trusts will
receive from the Units sold.

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. 

As stated under "Public Market" below, the Sponsor currently intends
to maintain a secondary market for Units for the period indicated. In so
maintaining a market, the Sponsor will also realize profits or sustain losses
in the amount of any difference between the price at which Units are purchased
and the price at which Units are resold (which price includes the applicable
sales charge). In addition, the Sponsor will also realize profits or sustain
losses resulting from a redemption of such repurchased Units at a price above
or below the purchase price for such Units, respectively.

Public Market. Although it is not obligated to do so, the Sponsor currently
intends to maintain a market for the Units offered hereby through August
_____, 1999 and offer continuously to purchase Units at prices, subject to
change at any time, based upon the aggregate underlying value of the Equity
Securities (computed as indicated under "Offering Price" above and
"Rights of Unitholders--Redemption of Units" ). 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
such prices. In the event that a market is not maintained for the Units and
the Unitholder cannot find another purchaser, a Unitholder desiring to dispose
of his Units will be able to dispose of such 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 existence any price in excess of the Redemption
Price and, if so, the amount thereof. Units sold prior to such time as the
entire deferred sales charge on such Units has been collected will be assessed
the amount of the remaining deferred sales charge at the time of sale
(however, Units sold on or prior to the first Special Redemption Date will not
be assessed the unpaid $0.225 per Unit deferred sales charge remaining after
such date).

Tax-Sheltered Retirement Plans. Units are available for purchase in connection
with certain types of tax-sheltered retirement plans, including Individual
Retirement Accounts for the individuals, Simplified Employee Pension Plans for
employees, qualified plans for self-employed individuals, and qualified
corporate pension and profit sharing plans for employees. The purchase of
Units may be limited by the plans' provisions and does not itself establish
such plans.

RIGHTS OF UNITHOLDERS 

- --------------------------------------------------------------------------
Certificates. The Trustee is authorized to treat as the record owner of Units
that person who is registered as such owner on the books of the Trustee.
Ownership of Units will be evidenced by certificates unless a Unitholder or
the Unitholder's registered broker-dealer makes a written request to the
Trustee that ownership be in book entry form. Units are transferable by making
a written request to the Trustee and, in the case of Units evidenced by a
certificate, by presentation and surrender of such certificate to the Trustee
properly endorsed or accompanied by a written instrument or instruments of
transfer. A Unitholder must sign such written request, and such certificate or
transfer instrument, exactly as his name appears on the records of the Trustee
and on the face of any certificate representing the Units to be transferred
with the signature guaranteed by a participant in the Securities Transfer
Agents Medallion Program ("STAMP" ) or such other signature guarantee
program in addition to, or in substitution for, STAMP as may be accepted by
the Trustee. In certain instances the Trustee may require additional documents
such as, but not limited to, trust instruments, certificates of death,
appointments as executor or administrator or certificates of corporate
authority. Certificates will be issued in denominations of one Unit or any
whole multiple thereof.

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

Distributions of Income and Capital. Any dividends received by the Trust with
respect to the Equity Securities therein are credited by the Trustee to the
Income Account. Other receipts (e.g., capital gains, proceeds from the sale of
Securities, etc.) are credited to the Capital Account. Proceeds from the sales
of Securities to meet redemptions of Units shall be segregated within the
Capital Account from proceeds from the sale of Securities made to satisfy the
fees, expenses and charges of a Trust.

The Trustee will distribute any net income received with respect to any of the
Securities on or about the Income Account Distribution Date to Unitholders of
record on the preceding Record Date. See "Summary of Essential Financial
Information" . Proceeds received on the sale of any Securities, to the
extent not used to meet redemptions of Units, pay the deferred sales charge or
pay expenses, will be distributed on the Capital Account Distribution Date to
Unitholders of record on the preceding Capital Account Record Date. Proceeds
received from the disposition of any of the Securities after a record date and
prior to the following distribution date will be held in the Capital Account
and not distributed until the next distribution date applicable to such
Capital Account. The Trustee is not required to pay interest on funds held in
the Capital or Income Accounts (but may itself earn interest thereon and
therefore benefits from the use of such funds) nor to make a distribution from
the Income or Capital Accounts unless the amount available for distribution
therein shall equal at least $0.01 per Unit. 

The distribution to Unitholders as of each record date will be made on the
following distribution date or shortly thereafter and shall consist of each
Unitholder's pro rata share of the cash in the Income Account. Because
dividends are not received by the Trusts at a constant rate throughout the
year, such distributions to Unitholders are expected to fluctuate from
distribution to distribution. Persons who purchase Units will commence
receiving distributions only after such person becomes a record owner.
Notification to the Trustee of the transfer of Units is the responsibility of
the purchaser, but in the normal course of business such notice is provided by
the selling broker-dealer.

At the end of the initial offering period and each month thereafter, the
Trustee will deduct from the Capital Account amounts necessary to pay the
expenses of the Trust (as determined on the basis set forth under "Trust
Operating Expenses" ). The Trustee also may withdraw from the Income and
Capital Accounts such amounts, if any, as it deems necessary to establish a
reserve for any governmental charges payable out of a Trust. Amounts so
withdrawn shall not be considered a part of a Trust's assets until such time
as the Trustee shall return all or any part of such amounts to the appropriate
accounts. In addition, the Trustee may withdraw from the Income and Capital
Accounts such amounts as may be necessary to cover redemptions of Units. 

It is anticipated that the deferred sales charge will be collected from the
Capital Account. To the extent that amounts in the Capital Account are
insufficient to satisfy the then current deferred sales charge obligation,
Equity Securities may be sold to meet such shortfall. Distributions of amounts
necessary to pay the deferred portion of the sales charge will be made to an
account maintained by the Trustee for purposes of satisfying Unitholders'
deferred sales charge obligations.

Reinvestment Option. In the event that any distribution is made to Unitholders
prior to termination of the Trust, Unitholders will initially have each such
distribution of dividend income, capital gains and/or principal on their Units
automatically reinvested in additional Units under the "Automatic
Reinvestment Option" (to the extent Units may be lawfully offered for sale
in the state in which the Unitholder resides). Unitholders receiving Units
pursuant to participation in the Automatic Reinvestment Option will be subject
to the remaining deferred sales charge payments due on Units (assuming for
these purposes such Units had been outstanding during the primary offering
period). Unitholders may also elect to receive distributions of dividend
income, capital gains and/or principal on their Units in cash. To receive
cash, a Unitholder may either contact his or her broker or agent or file with
the Trustee a written notice of election at least five days prior to the
Record Date for which the first distribution is to apply. A Unitholder's
election to receive cash will apply to all Units owned by such Unitholder and
such election will remain in effect until changed by the Unitholder.

Reinvestment plan distributions may be reinvested in Units already held in
inventory by the Sponsor (see "Public Offering--Public Market" ) or,
until such time as additional Units cease to be issued by a Trust (see "
The Trusts" ), distributions may be reinvested in such additional Units. If
Units are unavailable in the secondary market, distributions which would
otherwise have been reinvested shall be paid in cash to the Unitholder on the
applicable Distribution Date.

Purchases of additional Units made pursuant to the reinvestment plan will be
made at the net asset value for Units as of the Evaluation Time on the related
Income or Capital Distribution Dates. Under the reinvestment plan, a Trust
will pay the Unitholder's distributions to the Trustee which in turn will
purchase for such Unitholder full and fractional Units and will send such
Unitholder a statement reflecting the reinvestment.

Unitholders may also elect to have each distribution of income, capital gains
and/or capital on their Units automatically reinvested in Class A shares of
certain Van Kampen American Capital or Morgan Stanley mutual funds which are
registered in the Unitholder's state of residence. Such mutual funds are
hereinafter collectively referred to as the "Reinvestment Funds" .

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

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

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

Reports Provided. The Trustee shall furnish Unitholders in connection with
each distribution a statement of the amount of income and the amount of other
receipts (received since the preceding distribution), if any, being
distributed, expressed in each case as a dollar amount representing the pro
rata share of each Unit outstanding. Within a reasonable period of time after
the end of each calendar year, the Trustee shall furnish to each person who at
any time during the calendar year was a registered Unitholder of a Trust a
statement (i) as to the Income Account: income received, deductions for
applicable taxes and for fees and expenses of the Trust, for redemptions of
Units, if any, and the balance remaining after such distributions and
deductions, expressed in each case both as a total dollar amount and as a
dollar amount representing the pro rata share of each Unit outstanding on the
last business day of such calendar year; (ii) as to the Capital Account: the
dates of disposition of any Securities and the net proceeds received
therefrom, deductions for payment of applicable taxes, fees and expenses of
the Trust held for distribution to Unitholders of record as of a date prior to
the determination and the balance remaining after such distributions and
deductions expressed both as a total dollar amount and as a dollar amount
representing the pro rata share of each Unit outstanding on the last business
day of such calendar year; (iii) a list of the Securities held by the Trust
and the number of Units outstanding on the last business day of such calendar
year; (iv) the Redemption Price per Unit based upon the last computation
thereof made during such calendar year; and (v) amounts actually distributed
during such calendar year from the Income and Capital Accounts, separately
stated, expressed as total dollar amounts.

In order to comply with federal and state tax reporting requirements,
Unitholders will be furnished, upon request to the Trustee, evaluations of the
Securities in the Trust furnished to it by the Evaluator. 

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 and, in the case of Units
evidenced by a certificate, by tendering such certificate to the Trustee, duly
endorsed or accompanied by proper instruments of transfer with signature
guaranteed as described above (or by providing satisfactory indemnity, as in
connection with lost, stolen or destroyed certificates) and by payment of
applicable governmental charges, if any. No redemption fee will be charged. On
the third business day following such tender, the Unitholder will generally
receive in cash (unless the redeeming Unitholder elects an In Kind
Distribution as described below) an amount for each Unit equal to the
Redemption Price per Unit next computed after receipt by the Trustee of such
tender of Units. The "date of tender" is deemed to be the date on
which Units are received by the Trustee, except that with respect to Units
received after the applicable Evaluation Time the date of tender is the next
business day as defined under "Public Offering--Offering Price" and
such Units will be deemed to have been tendered to the Trustee on such day for
redemption at the redemption price computed on that day. Units redeemed prior
to such time as the entire deferred sales charge has been collected will be
assessed the amount of the remaining deferred sales charge at the time of
redemption.

The Trustee is empowered to sell Securities in order to make funds available
for redemption if funds are not otherwise available in the Capital and Income
Accounts to meet redemptions. The Securities to be sold will be selected by
the Trustee from those designated on a current list provided by the Supervisor
for this purpose. Units so redeemed shall be cancelled. Units tendered for
redemption prior to such time as the entire deferred sales charge on such
Units has been collected will be assessed the amount of the remaining deferred
sales charge at the time of redemption.

Unitholders tendering 1,000 or more Units for redemption may request from the
Trustee, in lieu of a cash redemption, an in kind distribution ("In Kind
Distribution" ) of an amount and value of Securities per Unit equal to the
Redemption Price per Unit as determined as of the evaluation next following
the tender. An In Kind Distribution on redemption of Units will be made by the
Trustee through the distribution of each of the Securities in book-entry form
to the account of the Unitholder's bank or broker-dealer at Depository Trust
Company. The tendering Unitholder will receive his pro rata number of whole
shares of each of the Securities comprising the related Trust portfolio and
cash from the Capital Account equal to the fractional shares to which the
tendering Unitholder is entitled. The Trustee may adjust the number of shares
of any issue of Securities included in a Unitholder's In Kind Distribution to
facilitate the distribution of whole shares, such adjustment to be made on the
basis of the value of Securities on the date of tender. If funds in the
Capital Account are insufficient to cover the required cash distribution to
the tendering Unitholder, the Trustee may sell Securities according to the
criteria discussed above.

To the extent that Securities are redeemed in kind or sold, the size of a
Trust will be, and the diversity of the Trust may be, reduced. Sales may be
required at a time when Securities would not otherwise be sold and may result
in lower prices than might otherwise be realized. The price received upon
redemption may be more or less than the amount paid by the Unitholder
depending on the value of the Securities in the portfolio at the time of
redemption. Special federal income tax consequences will result if a
Unitholder requests an In Kind Distribution. See "Federal Taxation" .

The Redemption Price per Unit (as well as the secondary market Public Offering
Price) will be determined on the basis of the aggregate underlying value of
the Equity Securities, plus or minus cash, if any, in the Income and Capital
Accounts. On the Initial Date of Deposit, the Public Offering Price per Unit
(which includes the initial sales charge) exceeded the values at which Units
could have been redeemed by the amounts shown under "Summary of Essential
Financial Information" . The Redemption Price per Unit is the pro rata
share of each Unit in a Trust determined on the basis of (i) the cash on hand
in the Trust, (ii) the value of the Securities and (iii) dividends receivable
on the Equity Securities trading ex-dividend as of the date of computation,
less (a) amounts representing taxes or other governmental charges payable out
of the Trust, (b) the accrued expenses of the Trust and (c) any unpaid
deferred sales charge payments. The Evaluator may determine the value of the
Equity Securities in the following manner: if the Equity Securities are listed
on a national securities exchange, this evaluation is generally based on the
closing sale prices on that exchange (unless it is determined that these
prices are inappropriate as a basis for valuation) or, if there is no closing
sale price on that exchange, at the closing bid prices. If the Equity
Securities are not so listed or, if so listed and the principal market
therefore is other than on the exchange, the evaluation shall generally be
based on the current bid price on the over-the-counter market (unless these
prices are inappropriate as a basis for evaluation). If current bid prices are
unavailable, the evaluation is generally determined (a) on the basis of
current bid prices for comparable securities, (b) by appraising the value of
the Equity Securities on the bid side of the market or (c) by any combination
of the above.

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 any period during which the Securities and
Exchange Commission determines that trading on that Exchange is restricted or
an emergency exists, as a result of which disposal or evaluation of the
Securities is not reasonably practicable, or for such other periods as the
Securities and Exchange Commission may by order permit.

Special Redemption and Rollover in New Trust. It is expected that a special
redemption will be made of all Units held by any Unitholder (a "Rollover
Unitholder" ) who affirmatively notifies the Trustee in writing that he
desires to rollover his Units by the Rollover Notification Date specified in
the "Summary of Essential Financial Information" .

All Units of Rollover Unitholders will be redeemed on the Special Redemption
Date and the underlying Securities will be distributed to the Distribution
Agent on behalf of the Rollover Unitholders. On the Special Redemption Date
(as set forth in "Summary of Essential Financial Information" ), the
Distribution Agent will be required to sell all of the underlying Securities
on behalf of Rollover Unitholders. The sales proceeds will be net of brokerage
fees, governmental charges or any expenses involved in the sales.

The Distribution Agent will attempt to sell the Securities as quickly as is
practicable on the Special Redemption Date. The Sponsor does not anticipate
that the period will be longer than one day given that the Securities are
usually liquid. However, certain of the factors discussed under "Risk
Factors" could affect the ability of the Sponsor to sell the Securities
and thereby affect the length of the sale period somewhat. The liquidity of
any Security depends on the daily trading volume of the Security and the
amount that the Sponsor has available for sale on any particular day.

The Rollover Unitholders' proceeds will be invested in a new trust (the "
New Trust" ), if then being offered, which will contain a portfolio of
common stocks of companies diversified within a specific industry sector. The
proceeds of redemption will be used to buy New Trust units in the portfolio as
the proceeds become available.

The Sponsor intends to create a New Trust shortly prior to the Special
Redemption Date, dependent upon the availability and reasonably favorable
prices of the securities included in the New Trust portfolio, and it is
intended that Rollover Unitholders will be given first priority to purchase
the New Trust units. There can be no assurance, however, as to the exact
timing of the creation of the New Trust units or the aggregate number of New
Trust units which the Sponsor will create. The Sponsor may, in its sole
discretion, stop creating new units in a trust portfolio at any time it
chooses, regardless of whether all proceeds of the Special Redemption have
been invested on behalf of Rollover Unitholders. Cash which has not been
invested on behalf of the Rollover Unitholders in New Trust units will be
distributed shortly after the Special Redemption Date.

Any Rollover Unitholder may thus be redeemed out of the Trust and become a
holder of an entirely different unit investment trust in the New Trust with a
different portfolio of Securities. The Rollover Unitholders' Units will be
redeemed and the distributed Securities shall be sold on the Special
Redemption Date. In accordance with the Rollover Unitholders' offer to
purchase the New Trust units, the proceeds of the sales (and any other cash
distributed upon redemption) will be invested in the New Trust at the public
offering price, including a reduced sales charge.

This process of redemption and rollover into a new trust is intended to allow
for the fact that the portfolios selected by the Sponsor is chosen on the
basis of growth potential only for the near term, at which point a new
portfolio is chosen. It is contemplated that a similar process of redemption
and rollover in new unit investment trusts will be available for each
subsequent series of the Trusts.

There can be no assurance that the redemption and rollover in a new trust will
avoid any negative market price consequences stemming from the trading of
large volumes of securities and of the underlying Securities. The above
procedures may be insufficient or unsuccessful in avoiding such price
consequences. In fact, market price trends may make it advantageous to sell or
buy more quickly or more slowly than permitted by these procedures. Investors
should note that, because aggressive growth stocks generally experience stock
price volatility to a greater extent than other securities and because the
Trust is not a "managed" fund, there can be no assurance that these
procedures will result in advantageous sales or purchases of securities or
that any future rollover will occur at an advantageous time. See "Trust
Administration--Portfolio Administration" and "Risk Factors" .

It should also be noted that Rollover Unitholders may realize taxable capital
gains on the Special Redemption and Rollover but, in certain circumstances,
will not be entitled to a deduction for certain capital losses and, due to the
procedures for investing in the subsequent trust, no cash would be distributed
at that time to pay any taxes. Included in the cash for the Special Redemption
and Rollover will be any amount of cash attributable to the last distribution
of dividend income; accordingly, Rollover Unitholders also will not have such
cash distributed to pay any taxes. See "Federal Taxation" . Unitholders
who do not inform the Distribution Agent that they wish to have their Units so
redeemed and liquidated will not realize capital gains or losses due to the
Special Redemption and Rollover.

The Sponsor may for any reason, in its sole discretion, decide not to sponsor
subsequent trust, without penalty or incurring liability to any Unitholder. If
the Sponsor so decides, the Sponsor shall notify the Unitholders before the
Special Redemption Date would have commenced. The Sponsor may modify the terms
of any subsequent trust. The Sponsor may also modify the terms of the Special
Redemption and Rollover upon notice to the Unitholders prior to the Rollover
Notification Date specified in the "Summary of Essential Financial
Information" .

Pursuant to an exemptive order, each terminating Trust (and the Distribution
Agent on behalf of Rollover Unitholders) can sell Securities to a New Trust if
those Securities continue to meet the related investment strategy of the
respective Series. The exemption will enable each Trust to eliminate
commission costs on these transactions. The price for those securities will be
the closing sale price on the sale date on the exchange where the Securities
are principally traded, as certified by the Trustee.

TRUST ADMINISTRATION 

- --------------------------------------------------------------------------
Sponsor Purchases of Units. The Trustee shall notify the Sponsor of any Units
tendered for redemption. If the Sponsor's bid in the secondary market at that
time equals or exceeds the Redemption Price per Unit, it may purchase such
Units by notifying the Trustee before the close of business on the next
succeeding business day and by making payment therefore to the Unitholder not
later than the day on which the Units would otherwise have been redeemed by
the Trustee. Units held by the Sponsor may be tendered to the Trustee for
redemption as any other Units.

The offering price of any Units acquired by the Sponsor will be in accord with
the Public Offering Price described in the then currently effective prospectus
describing such Units. Any profit resulting from the resale of such Units will
belong to the Sponsor which likewise will bear any loss resulting from a lower
offering or redemption price subsequent to its acquisition of such Units.

Portfolio Administration. The portfolios of the Trusts are not "
managed" by the Sponsor, Supervisor or the Trustee; their activities
described herein are governed solely by the provisions of the Trust Agreement.
Traditional methods of investment management for a managed fund typically
involve frequent changes in a portfolio of securities on the basis of
economic, financial and market analyses. The Trusts, however, will not be
managed. The Trust Agreement, however, provides that the Sponsor may (but need
not) direct the Trustee to dispose of an Equity Security in certain events
such as the issuer having defaulted on the payment on any of its outstanding
obligations or the price of an Equity Security has declined to such an extent
or other such credit factors exist so that in the opinion of the Sponsor the
retention of such Securities would be detrimental to a Trust. Pursuant to the
Trust Agreement and with limited exceptions, the Trustee may sell any
securities or other properties acquired in exchange for Equity Securities such
as those acquired in connection with a merger or other transaction. If offered
such new or exchanged securities or property, the Trustee shall reject the
offer. However, in the event such securities or property are nonetheless
acquired by a Trust, they may be accepted for deposit in the Trust and either
sold by the Trustee or held in the Trust pursuant to the direction of the
Sponsor (who may rely on the advice of the Supervisor). Proceeds from the sale
of Securities (or any securities or other property received by a Trust in
exchange for Equity Securities) are credited to the Capital Account for
distribution to Unitholders or to pay certain costs or expenses of the Trust.
Except as stated under "Trust Portfolios" for failed securities and as
provided in this paragraph, the acquisition by the Trust of any securities
other than the Securities is prohibited.

As indicated under "Rights of Unitholders--Redemption of Units" above,
the Trustee may also sell Securities designated by the Supervisor, or if no
such designation has been made, in its own discretion, for the purpose of
redeeming Units tendered for redemption and the payment of expenses.

To the extent practicable, the Supervisor may (but is not obligated to)
designate Securities to be sold by the Trustee in order to maintain the
proportionate relationship among the number of shares of individual issues of
Equity Securities in a Trust. To the extent this is not practicable, the
composition and diversity of the Equity Securities in a Trust may be altered.
In order to obtain the best price for a Trust, it may be necessary for the
Supervisor to specify minimum amounts (generally 100 shares) in which blocks
of Equity Securities are to be sold. In effecting purchases and sales of a
Trust's portfolio securities, the Sponsor may direct that orders be placed
with and brokerage commissions be paid to brokers, including brokers which may
be affiliated with the Trust, the Sponsor or dealers participating in the
offering of Units. In addition, in selecting among firms to handle a
particular transaction, the Sponsor may take into account whether the firm has
sold or is selling units of unit investment trusts which it sponsors.

Amendment or Termination. The Trust Agreement may be amended by the Trustee
and the Sponsor without the consent of any of the Unitholders (1) to cure any
ambiguity or to correct or supplement any provision thereof which may be
defective or inconsistent, or (2) to make such other provisions as shall not
adversely affect the Unitholders (as determined in good faith by the Sponsor
and the Trustee), provided, however, that the Trust Agreement may not be
amended to increase the number of Units (except as provided in the Trust
Agreement). The Trust Agreement may also be amended in any respect by the
Trustee and Sponsor, or any of the provisions thereof may be waived, with the
consent of the holders representing 51% of the Units of a Trust then
outstanding, provided that no such amendment or waiver will reduce the
interest in such Trust of any Unitholder without the consent of such
Unitholder or reduce the percentage of Units required to consent to any such
amendment or waiver without the consent of all Unitholders. The Trustee shall
advise the Unitholders of any amendment promptly after execution thereof.

A Trust may be liquidated at any time by consent of Unitholders representing
66 2/3% of the Units then outstanding or by the Trustee when the value of the
Equity Securities owned by the Trust, as shown by any evaluation, is less than
that amount set forth under Minimum Termination Value in "Summary of
Essential Financial Information." A Trust will be liquidated by the
Trustee in the event that a sufficient number of Units not yet sold are
tendered for redemption by the Sponsor so that the net worth of the Trust
would be reduced to less than 40% of the value of the Securities at the time
they were deposited in the Trust. If a Trust is liquidated because of the
redemption of unsold Units by the Sponsor, the Sponsor will refund to each
purchaser of Units the entire sales charge paid by such purchaser. The Trust
Agreement will terminate upon the sale or other disposition of the last
Security in a Trust held thereunder, but in no event will it continue beyond
the Mandatory Termination Date stated under "Summary of Essential
Financial Information" . 

Commencing on the Mandatory Termination Date, Equity Securities will begin to
be sold in connection with the termination of the Trusts. The Sponsor will
determine the manner, timing and execution of the sales of the Equity
Securities. The Sponsor shall direct the liquidation of the Securities in such
manner as to effectuate orderly sales and a minimal market impact. In the
event the Sponsor does not so direct, the Securities shall be sold within a
reasonable period and in such manner as the Trustee, in its sole discretion,
shall determine. At least 30 days before the Mandatory Termination Date the
Trustee will provide written notice of any termination to all Unitholders and
will include with such notice a form to enable Unitholders owning 1,000 or
more Units to request an In Kind Distribution rather than payment in cash upon
the termination of a Trust. To be effective, this request must be returned to
the Trustee at least five business days prior to the Mandatory Termination
Date. On the Mandatory Termination Date (or on the next business day
thereafter if a holiday) the Trustee will deliver each requesting Unitholder's
pro rata number of whole shares of each of the Securities to the account of
the broker-dealer or bank designated by the Unitholder at Depository Trust
Company. The value of the Unitholder's fractional shares of the Securities
will be paid in cash. Unitholders with less than 1,000 Units, Unitholders with
1,000 or more Units not requesting an In Kind Distribution and Unitholders who
do not elect the Rollover Option will receive a cash distribution from the
sale of the remaining Securities within a reasonable time following the
Mandatory Termination Date. Regardless of the distribution involved, the
Trustee will deduct from the funds of the Trusts any accrued costs, expenses,
advances or indemnities provided by the Trust Agreement, including estimated
compensation of the Trustee, costs of liquidation and any amounts required as
a reserve to provide for payment of any applicable taxes or other governmental
charges. Any sale of Securities upon termination may result in a lower amount
than might otherwise be realized if such sale were not required at such time.
The Trustee will then distribute to each Unitholder his pro rata share of the
balance of the Income and Capital Accounts.

The Sponsor currently intends to, but is not obligated to, offer for sale
units of a subsequent trust pursuant to the Rollover Option (see "Rights
of Unitholders--Special Redemption and Rollover in New Trust" ). There is,
however, no assurance that units of any new trust will be offered for sale at
that time, or if offered, that there will be sufficient units available for
sale to meet the requests of any or all Unitholders.

Within 60 days of the final distribution Unitholders will be furnished a final
distribution statement of the amount distributable. At such time as the
Trustee in its sole discretion will determine that any amounts held in reserve
are no longer necessary, it will make distribution thereof to Unitholders in
the same manner.

Limitations on Liabilities. The Sponsor, the Evaluator, the Supervisor and the
Trustee shall be under no liability to Unitholders for taking any action or
for refraining from taking any action in good faith pursuant to the Trust
Agreement, or for errors in judgment, but shall be liable only for their own
willful misfeasance, bad faith or gross negligence (negligence in the case of
the Trustee) in the performance of their duties or by reason of their reckless
disregard of their obligations and duties hereunder.

The Trustee shall not be liable for depreciation or loss incurred by reason of
the sale by the Trustee of any of the Securities. In the event of the failure
of the Sponsor to act under the Trust Agreement, the Trustee may act
thereunder and shall not be liable for any action taken by it in good faith
under the Trust Agreement. The Trustee shall not be liable for any taxes or
other governmental charges imposed upon or in respect of the Securities or
upon the interest thereon or upon it as Trustee under the Trust Agreement or
upon or in respect of 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, Sponsor, Supervisor and Unitholders may rely on any evaluation
furnished by the Evaluator and shall have no responsibility for the accuracy
thereof. Determinations by the Evaluator under the Trust Agreement shall be
made in good faith upon the basis of the best information available to it,
provided, however, that the Evaluator shall be under no liability to the
Trustee, Sponsor or Unitholders for errors in judgment. This provision shall
not protect the Evaluator in any case of willful misfeasance, bad faith, gross
negligence or reckless disregard of its obligations and duties.

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

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

Van Kampen American Capital Distributors, Inc. specializes in the underwriting
and distribution of unit investment trusts and mutual funds with roots in
money management dating back to 1926. The Sponsor is a member of the National
Association of Securities Dealers, Inc. and has offices at One Parkview Plaza,
Oakbrook Terrace, Illinois 60181, (630) 684-6000 and 2800 Post Oak Boulevard,
Houston, Texas 77056, (713) 993-0500. It maintains a branch office in
Philadelphia and has regional representatives in Atlanta, Dallas, Los Angeles,
New York, San Francisco and Seattle. As of November 30, 1996, the total
stockholders' equity of Van Kampen American Capital Distributors, Inc. was
$129,451,000 (unaudited). (This paragraph relates only to the Sponsor and not
to the Trusts or to any other Series thereof. The information is included
herein only for the purpose of informing investors as to the financial
responsibility of the Sponsor and its ability to carry out its contractual
obligations. More detailed financial information will be made available by the
Sponsor upon request.)

As of September 30, 1997, the Sponsor and its Van Kampen American Capital
affiliates managed or supervised approximately $65.3 billion of investment
products, of which over $10.85 billion is invested in municipal securities.
The Sponsor and its Van Kampen American Capital affiliates managed $54 billion
of assets, consisting of $34.3 billion for 55 open-end mutual funds (of which
45 are distributed by Van Kampen American Capital Distributors, Inc.) $14.2
billion for 37 closed-end funds and $5.5 billion for 106 institutional
accounts. The Sponsor has also deposited approximately $26 billion of unit
investment trusts. All of Van Kampen American Capital's open-end funds,
closed-ended funds and unit investment trusts are professionally distributed
by leading financial firms nationwide. Based on cumulative assets deposited,
the Sponsor believes that it is the largest sponsor of insured municipal unit
investment trusts, primarily through the success of its Insured Municipals
Income Trust(R)or the IM-IT(R)trust. The Sponsor also provides
surveillance and evaluation services at cost for approximately $13 billion of
unit investment trust assets outstanding. Since 1976, the Sponsor has serviced
over two million investor accounts, opened through retail distribution firms.

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

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

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

In accordance with the Trust Agreement, the Trustee shall keep proper books of
record and account of all transactions at its office for the Trusts. Such
records shall include the name and address of, and the number of Units held
by, every Unitholder of the Trusts. Such books and records shall be open to
inspection by any Unitholder at all reasonable times during the usual business
hours. The Trustee shall make such annual or other reports as may from time to
time be required under any applicable state or federal statute, rule or
regulation (see "Rights of Unitholders--Reports Provided" ). The
Trustee is required to keep a certified copy or duplicate original of the
Trust Agreement on file in its office available for inspection at all
reasonable times during the usual business hours by any Unitholder, together
with a current list of the Securities held in each Trust. 

Under the Trust Agreement, the Trustee or any successor trustee may resign and
be discharged of its responsibilities created by the Trust Agreement by
executing an instrument in writing and filing the same with the Sponsor. The
Trustee or successor trustee must mail a copy of the notice of resignation to
all Unitholders then of record, not less than 60 days before the date
specified in such notice when such resignation is to take effect. The Sponsor
upon receiving notice of such resignation is obligated to appoint a successor
trustee promptly. If, upon such resignation, no successor trustee has been
appointed and has accepted the appointment within 30 days after notification,
the retiring Trustee may apply to a court of competent jurisdiction for the
appointment of a successor. The Sponsor may remove the Trustee and appoint a
successor trustee as provided in the Trust Agreement at any time with or
without cause. Notice of such removal and appointment shall be mailed to each
Unitholder by the Sponsor. Upon execution of a written acceptance of such
appointment by such successor trustee, all the rights, powers, duties and
obligations of the original trustee shall vest in the successor. The
resignation or removal of a Trustee becomes effective only when the successor
trustee accepts its appointment as such or when a court of competent
jurisdiction appoints a successor trustee.

Any corporation into which a Trustee may be merged or with which it may be
consolidated, or any corporation resulting from any merger or consolidation to
which a Trustee shall be a party, shall be the successor trustee. The Trustee
must be a banking corporation organized under the laws of the United States or
any state and having at all times an aggregate capital, surplus and undivided
profits of not less than $5,000,000.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Board of Directors of Van Kampen American Capital Distributors, Inc.
and the Unitholders of Van Kampen American Capital Equity Opportunity Trust,
Series 90:

We have audited the accompanying statements of condition and the related
portfolios of Van Kampen American Capital Equity Opportunity Trust, Series 90
as of February 17, 1998. The statements of condition and portfolios are the
responsibility of the Sponsor. Our responsibility is to express an opinion on
such financial statements based on our audit.

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

We believe our audit provides a reasonable basis for our opinion. In our
opinion, the financial statements referred to above present fairly, in all
material respects, the financial position of Van Kampen American Capital
Equity Opportunity Trust, Series 90 as of February 17, 1998, in conformity
with generally accepted accounting principles.
