(1) Each Security is valued at the most recent closing sale price on its
principal trading exchange or at the most recent asked price if not
listed on the last business day before the Initial Date of Deposit.
You will bear all or a portion of the expenses incurred in organizing
and offering your Trust. The public offering price includes the

expenses from your Trust at the end of the initial offering period
(approximately two months). The estimated amount for each Trust is
described on the next page.

(2) The public offering price will include any accumulated dividends or
cash in the Income or Capital Accounts of a Trust.

(3) At the close of the New York Stock Exchange on the Initial Date of
Deposit, the number of Units may be adjusted so that the public
offering price per Unit equals $10. The number of Units and fractional
interest of each Unit in a Trust will increase or decrease to the
extent of any adjustment.

(4) This estimate is based on the most recently declared quarterly
dividends or interim and final dividends accounting for any foreign
withholding taxes. Actual dividends may vary due to a variety of
factors. See "Risk Factors".

(5) The redemption price is reduced by any remaining deferred sales
charge. See "Rights of Unitholders--Redemption of Units". The
redemption price includes the estimated organizational and offering
costs. The redemption price will not included these costs after the

This fee table is intended to assist you in understanding the costs that you
will bear and to present a comparison of fees. The "Estimated Costs Over Time"
example illustrates the expenses you would pay on a $1,000 investment assuming a
5% annual return and redemption at the end of each period. This example assumes
that you reinvest all distributions at the end of each year. Of course, you
should not consider this example a representation of actual past or future
expenses or annual rate of return which may differ from those assumed for this
example. The sales charge and expenses are described under "Public Offering" and
"Trust Operating Expenses".

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

(1) The initial sales charge is the difference between the maximum sales
charge and the deferred sales charge.

(2) The deferred sales charge is actually equal to $0.225 per Unit. This
amount will exceed the percentage above if the public offering price
per Unit falls below $10 and will be less than the percentage above if
the public offering price per Unit exceeds $10. The deferred sales
charge accrues daily and is assessed from September 21, 1999 through
May 20, 2000.

(3) You will bear all or a portion of the expenses incurred in organizing
and offering your Trust. The Trustee will deduct the actual amount of
these expenses from your Trust at the end of the initial offering
period.

Internet Trust

The Trust seeks to increase the value of your Units over time by investing in
a portfolio of common stocks of companies primarily involved in the enabling
technology or communication services areas of the Internet. In selecting these
stocks, we considered companies engaged in one or more of the following areas:

o Manufacturers or providers of enabling technology

o Access equipment

o Communications equipment

o Service providers

o Access and value-added services

o Commerce and value-added services

o Software and network services

With a computer and access to the Internet you are connected to the world.
You can gather information, have a conversation, make a reservation or pay a
bill. This Trust may offer the potential to benefit from one of the latest
technological innovations. Consider that experts expect:

o The internet audience to increase from 100 million by the end of 1998
to 320 million by 2002

o The percentage of World Wide Web users making purchases online to grow
from 26% in 1997 to 40% in 2002

o World Wide Web commerce to increase from $2.6 billion in 1996 to $400
billion in 2002 (International Data Corporation)

Of course, we cannot guarantee that the Trust will achieve its objective. The
value of your Units may fall below the price you paid for the Units. Stocks of
internet-related companies have been subject to extreme price volatility and
speculative trading. This Trust is appropriate for aggressive investors or as an
aggressive growth component of your investment portfolio. You should read the
"Risk Factors" section before you invest.

Morgan Stanley High-Technology 35 IndexSM Trust

The Trust seeks to provide capital appreciation through an investment in a
portfolio of the common stocks included in the Morgan Stanley High-Technology 35
IndexSM on the Initial Date of Deposit. In creating the index, the Morgan
Stanley Technology Research Group sought to design a benchmark that provides
broad industry representation of equally-weighted, highly liquid, pure
technology companies that is rebalanced annually. Morgan Stanley set the index
value to 200 as of the close of trading on December 18, 1994. The American Stock
Exchange computes the value of the index in real-time during trading hours under
the symbol "MSH". The index is the exclusive property and is a service mark of
Morgan Stanley.

If you had invested $10,000 in the stocks included in the index on December
31, 1993, it would have grown to $61,826 by March 31, 1998. If you had invested
this amount in the stocks included in the Standard & Poor's 500 Index and
Nasdaq-100 Index, it would have grown to $30,608 and $53,370 over the same time
period. This is not the past performance of the Trust or a previous series of
the Trust and does not indicate the future performance of the Trust. The
performance figure for the High-Tech 35 Index reflects hypothetical Trust sales
charges and expenses. The performance of the Trust will differ from the index
because the Trust includes a sales charge and expenses. In addition, the Trust
may not be able to exactly replicate the index and will not necessarily change
if the index changes.

Pure Technology. The index includes 35 pure technology companies representing
the full breadth of technology industry segments. These segments include
Computer Services, Networking and Telecommunications Equipment, PC Hardware and
Peripherals, Electronic Connectors and Components, Server/Technical Software,
Wireless Telecommunications Equipment, Semiconductor Capital Equipment, PC
Software/Internet/New Media and Server Hardware and Semiconductors. The index
attempts to include bellwether stocks that provide a balanced representation of
these sub-industries. The index includes only electronics-based technology
companies and excludes biotechnology, medical, test and instrumentation
companies.

Equal Weighting. The index is an equal weighted index that includes large and
small industry bellwether stocks. The index seeks to minimize the pitfalls of
market capitalization indexes. Morgan Stanley believes that market
capitalization indexes fail to accommodate the wide range of market
capitalizations and revenue bases common to the technology industry.

Rebalancing. Morgan Stanley rebalances the index to an equal weighting per
company on the third Friday of each December. This allows stocks that appreciate
during the year to command increasing influence in the index while guarding
against the long-term negatives of a market-capitalization weighted index. We
will not rebalance the Trust portfolio annually. Changes in the index will not
necessarily result in changes in the portfolio. However, we may offer additional
portfolios each year that include the current index components and weightings.
Certain companies in the index have announced their intention to merge or
combine operations in the near future. While the Trust may continue to hold the
stock of any new entities received in exchange for the current stocks, it will
not reinvest in any new stocks that may be added to the index. Accordingly, the
Trust portfolio is likely to differ from the index components during its life.

As with any investment, we cannot guarantee that the Trust will achieve its
objective. The value of your Units may fall below the price you paid for the
Units. You should read the "Risk Factors" Section before you invest.

to pay for all or a portion of the costs incurred in establishing a
Trust. The amount of these costs are set forth in the "Fee Table." A
distribution will be made as of the close of the initial offering
period to an account maintained by the Trustee from which this
obligation of the investors will be satisfied.

(3) Represents the amount of mandatory distributions from a Trust on the
bases set forth under "Public Offering".

THE TRUSTS
- --------------------------------------------------------------------------------

The Trusts were 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 Funds Inc., as
Sponsor, Van Kampen Investment Advisory Corp., as Supervisor, The Bank of New
York, as Trustee, and American Portfolio Evaluation Services, a division of Van
Kampen Investment Advisory Corp., as Evaluator.
The Trusts offer investors the opportunity to purchase Units representing
proportionate interests in portfolios of actively traded equity securities. A
Trust may be an appropriate medium for investors who desire to participate in a
portfolio of common stocks with greater diversification than they might be able
to acquire individually.
On the Initial Date of Deposit, the Sponsor deposited delivery statements
relating to contracts for the purchase of the Securities and an irrevocable
letter of credit in the amount required for these purchases with the Trustee. In
exchange for these contracts the Trustee delivered to the Sponsor documentation
evidencing the ownership of Units of the Trusts. Unless otherwise terminated as
provided in the Trust Agreement, the Trusts will terminate on the Mandatory
Termination Date and any remaining Securities will be liquidated or distributed
by the Trustee within a reasonable time. As used in this Prospectus the term
"Securities" means the securities (including contracts to purchase these
securities) listed in "Portfolio" for each Trust and any additional securities
deposited into each Trust.
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, the aggregate value of the Securities will be increased and
the fractional undivided interest represented by each Unit will be decreased.
The Sponsor may continue to make additional deposits into a Trust following the
Initial Date of Deposit provided that the additional deposits will be in amounts
which will maintain, as nearly as practicable, the same percentage relationship
among the number of shares of each Security in the Trustportfolio that existed
immediately prior to the subsequent deposit. Investors may experience a dilution
of their investments and a reduction in their anticipated income 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 or acquisition fees.
Each Unit of a Trust initially offered represents an undivided interest in
that 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 that Trust represented by
each unredeemed Unit will increase or decrease accordingly, although the actual
interest in the Trust 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.
Each Trust consists of (a) the Securities (including contracts for the
purchase thereof) listed under the applicable "Portfolio" as may continue to be
held from time to time in the Trust, (b) any additional Securities acquired and
held by the Trust pursuant to the provisions of the Trust Agreement and (c) any
cash held in the related Income and Capital Accounts. Neither the Sponsor nor
the Trustee shall be liable in any way for any failure in any of the Securities.

OBJECTIVES AND SECURITIES SELECTION
- --------------------------------------------------------------------------------

Each Trust seeks to increase the value of your investment by investing in a
portfolio of common stocks of companies diversified within a particular
industry. We cannot guarantee that a Trust will achieve its objective.
You should note that we applied the selection criteria to the Securities for
inclusion in the Trusts as of the Initial Date of Deposit. After this date, the
Securities may no longer meet the selection criteria. Should a Security no
longer meet the selection criteria, we will generally not remove the Security
from its Trust portfolio.
A balanced investment portfolio incorporates various style and capitalization
characteristics. We offer unit trusts with a variety of styles and
capitalizations to meet your needs. We determine style characteristics (growth
or value) based on the criteria used in selecting the Trust portfolio.
Generally, a growth portfolio includes companies in a growth phase of their
business with increasing earnings. A value portfolio generally includes
companies with low relative price-earnings ratios that we believe are
undervalued. We determine market capitalizations as follows based on the
weighted median market capitalization of a portfolio: Small-Cap-- less than $1
billion; Mid-Cap-- $1 billion to $5 billion; and Large-Cap-- over $5 billion. We
determine all style and capitalization characteristics as of the Initial Date of
Deposit and the characteristics may vary thereafter. We will not remove a
Security from a Trust as a result of any change in characteristics.

RISK FACTORS
- --------------------------------------------------------------------------------

Price Volatility. The Trusts invest in common stocks of U.S. and foreign
companies. The value of Units will fluctuate with the value of these stocks and
may be more or less than the price you originally paid for your Units. The
market value of common stocks sometimes moves up or down rapidly and
unpredictably. Because the Trusts are unmanaged, the Trustee will not sell
stocks in response to market fluctuations as is common in managed investments.
In addition, because some Trusts hold a relatively small number of stocks, you
may encounter greater market risk than in a more diversified investment. As with
any investment, we cannot guarantee that the performance of a Trust will be
positive over any period of time.
Dividends. Common stocks represent ownership interests in the issuers and are
not obligations of the issuers. Accordingly, common stockholders have a right to
receive dividends only after the company has provided for payment of its
creditors, bondholders and preferred stockholders. Common stocks do not assure
dividend payments. Dividends are paid only when declared by an issuer's board of
directors and the amount of any dividend may vary over time.
Technology Issuers. Each Trust invests in a single industry. Any negative
impact on the technology industry will have a greater impact on the value of
Units than on a portfolio diversified over several industries. You should
understand the risks of the technology industry before you invest.
Technology companies face risks related to rapidly changing technology, rapid
product obsolescence, cyclical market patterns, evolving industry standards and
frequent new product introductions. An unexpected change in technology can have
a significant negative impact on a company. The failure of a company to
introduce new products or technologies or keep pace with rapidly changing
technology, can have a negative impact on the company's results. Technology
stocks tend to experience substantial price volatility and speculative trading.
Announcements about new products, technologies, operating results or marketing
alliances can cause stock prices to fluctuate dramatically. At times, however,
extreme price and volume fluctuations are unrelated to the operating performance
of a company. This can impact your ability to redeem your Units at a price equal
to or greater than what you paid.
The market for certain products may have only recently begun to develop, is
rapidly evolving or is characterized by increasing suppliers. Key components of
some technology products are available only from limited sources. This can
impact the cost of and ability to acquire these components. Some technology
companies serve highly concentrated customer bases with a limited number of
large customers. Any failure to meet the standard of these customers can result
in a significant loss or reduction in sales. Many products and technologies are
incorporated into other products. As a result, some companies are highly
dependent on the performance of other technology companies. We cannot guarantee
that these customers will continue to place additional orders or will place
orders in similar quantities as in the past.
No FDIC Guarantee. An investment in your Trust is not a deposit of any bank
and is not insured or guaranteed by the Federal Deposit Insurance Corporation or
any other government agency.
Year 2000 Readiness Disclosure. These two paragraphs constitute "Year 2000
Readiness Disclosure" within the meaning of the Year 2000 Information and
Readiness Disclosure Act of 1998. If computer systems used by the Sponsor,
Evaluator, Supervisor, Trustee or other service providers to the Trusts do not
properly process date-related information after December 31, 1999, the resulting
difficulties could adversely impact the Trusts. This is commonly known as the
"Year 2000 Problem." The Sponsor, Evaluator, Supervisor and Trustee are taking
steps to address this problem and to obtain reasonable assurances that other
service providers to the Trusts are taking comparable steps. We cannot guarantee
that these steps will be sufficient to avoid any adverse impact on the Trusts.
This problem may impact corporations to varying degrees based on factors such as
industry sector and degree of technological sophistication. We cannot predict
what impact, if any, this problem will have on the issuers of the Securities.
In addition, computer failures throughout the financial services industry
beginning January 1, 2000 could have a detrimental effect on the markets for the
Securities. Improperly functioning trading systems may result in settlement
problems and liquidity issues. Moreover, corporate and governmental data
processing errors may adversely affect issuers and overall economic
uncertainties. Remediation costs will affect the earnings of individual issuers.
These costs could be substantial. Issuers may report these costs inconsistently
in U.S. and foreign financial markets. All of these issues could adversely
affect the Securities and the Trusts.

PUBLIC OFFERING
- --------------------------------------------------------------------------------

General. Units are offered at the Public Offering Price which includes the
underlying value of the Securities, the initial sales charge, and cash, if any,
in the Income and Capital Accounts. The "Fee Table" describes the sales charges
in detail. If any deferred sales charge payment date is not a business day, we
will charge the payment on the next business day. If you purchase Units after
the initial deferred sales charge payment, you will only pay that portion of the
payments not yet collected. A portion of the Public Offering Price includes an
amount of Securities to pay for all or a portion of the costs incurred in
establishing your Trust, including the cost of preparing documents relating to
the Trust (such as the prospectus, trust agreement and closing documents,
federal and state registration fees, the initial fees and expenses of the
Trustee and legal and audit expenses). Beginning on June 15, 2000, the secondary
market sales charge will be 2.75% and will not include deferred payments. The
initial offering period sales charge is reduced as follows:

Aggregate
Dollar Amount
of Units Purchased* Sales Charge
- --------------------- ----------------
$100,000 - $249,999 3.00%
$250,000 - $499,999 2.75
$500,000 - $999,999 2.50
$1,000,000 or more 2.00

- ---------------
*The breakpoint sales charges are also applied on a Unit 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.

Any sales charge reduction is the responsibility of the selling broker,
dealer or agent. An investor may aggregate purchases of Units of the Trusts for
purposes of qualifying for volume purchase discounts listed above. The reduced
sales charge structure will also apply on all purchases by the same person from
any one dealer of units of Van Kampen-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 the
units purchased are of a unit investment trust purchased on the Initial Purchase
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 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 the amount of such reduction. To
determine the applicable sales charge reduction 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 to be additional purchases by the purchaser for the
purposes of calculating the applicable sales charge. 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. If you purchase Units on
more than one day to achieve the discounts described in this paragraph, the
discount allowed on any single day will apply only to Units purchased on that
day (a retroactive discount is not given on all prior purchases).
Units may be purchased in the primary or secondary market at the Public
Offering Price less the concession the Sponsor typically allows to brokers and
dealers for purchases by (1) investors who purchase Units through registered
investment advisers, certified financial planners and registered broker-dealers
who in each case either charge periodic fees for 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.
During the initial offering period, unitholders of any Van Kampen-sponsored
unit investment trust may utilize their redemption or termination proceeds to
purchase Units of all Trusts at the Public Offering Price per Unit less 1%.
Employees, officers and directors (including their spouses, children,
grandchildren, parents, grandparents, siblings, mothers-in-law, fathers-in-law,
sons-in-law, daughters-in-law, and trustees, custodians or fiduciaries for the
benefit of such persons) of the Van Kampen Funds Inc. and its affiliates,
dealers and their affiliates and vendors providing services to the Sponsor may
purchase Units at the Public Offering Price less the applicable dealer
concession.
The minimum purchase is 100 Units (25 Units for retirement accounts) but may
vary by selling firm. However, 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.
Offering Price. The Public Offering Price of Units will vary from the amounts
stated under "Summary of Essential Financial Information" in accordance with
fluctuations in the prices of the underlying Securities in the Trusts. The
initial price of the Securities was determined by Interactive Data Corporation,
a firm regularly engaged in the business of evaluating, quoting or appraising
comparable securities. The Evaluator will generally determine the value of the
Securities as of the Evaluation Time on each business day and will adjust the
Public Offering Price of Units accordingly. This Public Offering Price will be
effective for all orders received prior to the Evaluation Time on each business
day. The Evaluation Time is the close of the New York Stock Exchange on each
Trust business 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,
will be held until the next determination of price. The term "business day", as
used herein and under "Rights of Unitholders--Redemption of Units", excludes
Saturdays, Sundays and holidays observed by the New York Stock Exchange.
The aggregate underlying value of the Securities during the initial offering
period is determined on each business day by the Evaluator in the following
manner: If the Securities are listed on a national or foreign 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 Securities are not listed on a national or foreign
securities exchange or, if so listed and the principal market therefor 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
Securities on the ask side of the market or (c) by any combination of the above.
The value of any foreign securities is based on the applicable currency exchange
rate as of the Evaluation Time. The value of the Securities for purposes of
secondary market transactions and redemptions is described under "Rights of
Unitholders--Redemption of Units".
In offering the Units to the public, neither the Sponsor nor any
broker-dealers are recommending any of the individual Securities but rather the
entire pool of Securities in a Trust, taken as a whole, which are represented by
the Units.
Unit Distribution. Units will be distributed to the public by the Sponsor,
broker-dealers and others at the Public Offering Price. 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 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
described below.

Aggregate Concession
Dollar Amount or Agency
of Units Purchased* Commission
- --------------------- ----------------
Up to $99,999 2.25%
$100,000 - $249,999 2.00
$250,000 - $499,999 1.90
$500,000 - $999,999 1.75
$1,000,000 or more 1.40

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

*The breakpoint concessions or agency commissions are also applied on a Unit
basis using a breakpoint equivalent of $10 per Unit and are applied on whichever
basis is more favorable to the distributor.

In addition to the amounts above, during the initial offering period any firm
that distributes 500,000 - 999,999 Units of a single Trust will receive
additional compensation of $.005 per Unit of such Trust; any firm that
distributes 1,000,000 - 1,999,999 Units will receive additional compensation of
$.01 per Unit of such Trust; any firm that distributes 2,000,000 - 2,999,999
Units will receive additional compensation of $.015 per Unit of such Trust; any
firm that distributes 3,000,000 - 3,999,999 Units will receive additional
compensation of $.02 per Unit of such Trust. This additional compensation will
be paid by the Sponsor out of its own assets at the end of the initial offering
period.
Any discount provided to investors will be borne by the selling dealer or
agent as indicated under "General" above. For transactions involving unitholders
of other Van Kampen unit investment trusts who use their redemption or
termination proceeds to purchase Units of the Trusts, the total concession or
agency commission will amount to 1.50% per Unit. For all secondary market
transactions the total concession or agency commission will amount to 70% of the
sales charge. Notwithstanding anything to the contrary herein, in no case shall
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 exceed the total sales charge applicable to such
transaction. 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.
Broker-dealers of the Trusts, 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 sponsored by the Sponsor, an amount
not exceeding the total applicable sales charges on the sales generated by such
persons at the public offering price during such programs. Also, the Sponsor in
its discretion may from time to time pursuant to objective criteria established
by the Sponsor pay fees to qualifying 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 the assets of any Trust. These programs will not change the price Unitholders
pay for their Units or the amount that a Trust will receive from the Units sold.
Sponsor Compensation. The Sponsor will receive a gross sales commission equal
to the total sales charge applicable to each transaction. Any sales charge
discount provided to investors will be borne by the selling dealer or agent. In
addition, the Sponsor will realize a profit or loss as a result of the
difference between the price paid for the Securities by the Sponsor and the cost
of the Securities to each Trust 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
realize profit or loss as a result of the possible fluctuations in the market
value of the Securities, since all proceeds received from purchasers of Units
are retained by the Sponsor. In maintaining a secondary market, the Sponsor will
realize profits or losses in the amount of any difference between the price at
which Units are purchased and the price at which Units are resold (which price
includes the applicable sales charge) or from a redemption of repurchased Units
at a price above or below the purchase price. 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.
An affiliate of the Sponsor may have participated in a public offering of one
or more of the Securities. The Sponsor, an affiliate or their employees may have
a long or short position in these Securities or related securities. An affiliate
may act as a specialist or market maker for these Securities. An officer,
director or employee of the Sponsor or an affiliate may be an officer or
director for issuers of the Securities.
Market for Units. Although it is not obligated to do so, the Sponsor
currently intends to maintain a market for Units and to purchase Units at the
secondary market repurchase price (which is described under "Right of
Unitholders--Redemption of Units"). The Sponsor may discontinue purchases of
Units or discontinue purchases at this price at any time. In the event that a
secondary market is not maintained, a Unitholder will be able to dispose of
Units by tendering them to the Trustee for redemption at the Redemption Price.
See "Rights of Unitholders--Redemption of Units". Unitholders should contact
their broker to determine the best price for Units in the secondary market.
Units sold prior to the time the entire deferred sales charge has been collected
will be assessed the amount of any remaining deferred sales charge at the time
of sale. The Trustee will notify the Sponsor of any tendered of Units for
redemption. If the Sponsor's bid in the secondary market equals or exceeds the
Redemption Price per Unit, it may purchase the Units not later than the day on
which Units would have been redeemed by the Trustee. The Sponsor may sell
repurchased Units at the secondary market Public Offering Price per Unit.
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 minimum
purchase for these accounts is reduced to 25 Units but may vary by selling firm.
The purchase of Units may be limited by the plans' provisions and does not
itself establish such plans.

RIGHTS OF UNITHOLDERS
- --------------------------------------------------------------------------------

Distributions. Dividends and any net proceeds from the sale of Securities
received by a Trust will generally be distributed to Unitholders on each
Distribution Date to Unitholders of record on the preceding Record Date. These
dates are listed under "Summary of Essential Financial Information". A person
becomes a Unitholder of record on the date of settlement (generally three
business days after Units are ordered). Unitholders may elect to receive
distributions in cash or to have distributions reinvested into additional Units.
Distributions may also be reinvested into Van Kampen mutual funds. See "Rights
of Unitholders--Reinvestment Option".
Dividends received by a Trust are credited to the Income Account of the
Trust. Other receipts (e.g., capital gains, proceeds from the sale of
Securities, etc.) are credited to the Capital Account. Proceeds received on the
sale of any Securities, to the extent not used to meet redemptions of Units or
pay deferred sales charges, fees or expenses, will be distributed to
Unitholders. Proceeds received from the disposition of any 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. Any
distribution to Unitholders consists of each Unitholder's pro rate share of the
available cash in the Income and Capital Accounts as of the related Record Date.
Reinvestment Option. Unitholders may have distributions 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) through two options, if available. Brokers and dealers can
use the Dividend Reinvestment Service through Depository Trust Company or
purchase the Automatic Reinvestment Option CUSIP, if available. Unitholders will
be subject to the remaining deferred sales charge payments due on Units. To
participate in this reinvestment option, a Unitholder must file with the Trustee
a written notice of election, together with any certificate representing Units
and other documentation that the Trustee may then require, at least five days
prior to the related Record Date. A Unitholder's election will apply to all
Units owned by the Unitholder and will remain in effect until changed by the
Unitholder. If Units are unavailable for reinvestment, distributions will be
paid in cash. 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 Distribution Date.
In addition, under the Guaranteed Reinvestment Option Unitholders may elect
to have distributions automatically reinvested in certain Van Kampen mutual
funds (the "Reinvestment Funds"). Each Reinvestment Fund has investment
objectives which differ from those of the Trusts. The prospectus relating to
each Reinvestment Fund describes its investment policies and how to begin
reinvestment. A Unitholder may obtain a prospectus for the Reinvestment Funds
from the Sponsor. Purchases of shares of a Reinvestment Fund will be made at a
net asset value computed on the Distribution Date. Unitholders with an existing
Guaranteed Reinvestment Option account (whereby a sales charge is imposed on
distribution reinvestments) may transfer their existing account into a new
account which allows purchases of Reinvestment Fund shares at net asset value.
A participant may elect to terminate his or her reinvestment plan and receive
future distributions in cash by notifying the Trustee in writing no later than
five days before a distribution date. The Sponsor, each Reinvestment Fund, and
its investment adviser shall have the right to suspend or terminate these
reinvestment plans at any time.
Redemption of Units. A Unitholder may redeem all or a portion of his Units by
tender to the Trustee at its Unit Investment Trust Division, 101 Barclay Street,
20th Floor, New York, New York 10286. Certificates must be tendered to the
Trustee, duly endorsed or accompanied by proper instruments of transfer with
signature guaranteed (or by providing satisfactory indemnity in connection with
lost, stolen or destroyed certificates) and by payment of applicable
governmental charges, if any. On the seventh day following the tender, the
Unitholder will be entitled to receive in cash an amount for each Unit equal to
the Redemption Price per Unit next computed on the date of tender. 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 by the Trustee after the Evaluation
Time or on a day which is not a Trust business day, the date of tender is deemed
to be the next business day.
Unitholders tendering 1,000 or more Units of a Trust for redemption may
request an in kind distribution of Securities equal to the Redemption Price per
Unit on the date of tender. Trusts generally do not offer in kind distributions
of portfolio securities that are held in foreign markets. An in kind
distribution 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 broker-dealer
at Depository Trust Company. Amounts representing fractional shares will be
distributed in cash. The Trustee may adjust the number of shares of any Security
included in a Unitholder's in kind distribution to facilitate the distribution
of whole shares.
The Trustee may sell Securities to satisfy Unit redemptions. To the extent
that Securities are redeemed in kind or sold, the size of a Trust will be, and
the diversity of a 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
at the time of redemption. Special federal income tax consequences will result
if a Unitholder requests an in kind distribution. See "Taxation".
The Redemption Price per Unit and the secondary market repurchase price per
Unit are equal to the pro rate share of each Unit in each Trust determined on
the basis of (i) the cash on hand in the Trust, (ii) the value of the Securities
in the Trust and (iii) dividends receivable on the Securities in the Trust
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. During
the initial offering period, the redemption price and the secondary market
repurchase price will also include estimated organizational costs. For these
purposes, the Evaluator may determine the value of the Securities in the
following manner: If the Securities are listed on a national or foreign
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 Securities are not so listed
or, if so listed and the principal market therefore is other than on the
exchange, the evaluation may be based on the current bid price on the
over-the-counter market. If current bid prices are unavailable or inappropriate,
the evaluation may be determined (a) on the basis of current bid prices for
comparable securities, (b) by appraising the Securities on the bid side of the
market or (c) by any combination of the above. The value of any foreign
securities is based on the applicable currency exchange rate as of the
Evaluation Time.
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 SEC 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 other periods as the SEC may permit.
Certificates. Ownership of Units is evidenced in book entry form unless a
Unitholder makes a written request to the Trustee that ownership be in
certificate form. Units are transferable by making a written request to the
Trustee and, in the case of Units in certificate form, by presentation of the
certificate to the Trustee properly endorsed or accompanied by a written
instrument or instruments of transfer. A Unitholder must sign the written
request, and certificate or transfer instrument, exactly as his name appears on
the records of the Trustee and on the face of any certificate with the signature
guaranteed by a participant in the Securities Transfer Agents Medallion Program
("STAMP") or a signature guarantee program 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. Fractional certificates
will not be issued. 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 transfer or interchange. Destroyed,
stolen, mutilated or lost certificates will be replaced upon delivery to the
Trustee of satisfactory indemnity, evidence of ownership and payment of expenses
incurred. Mutilated certificates must be surrendered to the Trustee for
replacement.
Reports Provided. Unitholders will receive a statement of dividends and other
amounts received by a Trust for each distribution. Within a reasonable time
after the end of each year, each person who was a Unitholder during that year
will receive a statement describing dividends and capital received, actual Trust
distributions, Trust expenses, a list of the Securities and other Trust
information. Unitholders may obtain the Evaluator's evaluations of the
Securities upon request.

TRUST ADMINISTRATION
- --------------------------------------------------------------------------------

Portfolio Administration. The Trusts are not managed funds and, except as
provided in the Trust Agreement, Securities generally will not be sold or
replaced. The Sponsor may, however, direct that Securities be sold in certain
limited circumstances to protect the Trust based on advice from the Supervisor.
These situations may include events such as the issuer having defaulted on
payment of any of its outstanding obligations or the price of a Security has
declined to such an extent or other credit factors exist so that in the opinion
of the Sponsor retention of the Security would be detrimental to the Trust. In
addition, the Trustee may sell Securities to redeem Units or pay Trust expenses
or deferred sales charges. The Trustee must reject any offer for securities or
property in exchange for the Securities. If securities or property are
nonetheless acquired by a Trust, the Sponsor may direct the Trustee to sell the
securities or property and distribute the proceeds to Unitholders or to accept
the securities or property for deposit in the Trust. Should any contract for the
purchase of any of the Securities fail, the Sponsor will (unless substantially
all of the moneys held in the Trust to cover the purchase are reinvested in
substitute Securities in accordance with the Trust Agreement) refund the cash
and sales charge attributable to the failed contract to all Unitholders on or
before the next distribution date.
When your Trust sells Securities, the composition and diversity of the
Securities in the 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 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 Trusts, 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 of the Trust Agreement. The Trustee and the Sponsor may amend the
Trust Agreement without the consent of Unitholders to correct any provision
which may be defective or to make other provisions that will not adversely
affect Unitholders (as determined in good faith by the Sponsor and the Trustee).
The Trust Agreement may not be amended to increase the number of Units or permit
acquisition of securities in addition to or substitution for the Securities
(except as provided in the Trust Agreement). The Trustee will notify Unitholders
of any amendment.
Termination. Each Trust will terminate on the Mandatory Termination Date or
upon the sale or other disposition of the last Security held in the Trust. A
Trust may be terminated at any time with consent of Unitholders representing
two-thirds of the outstanding Units or by the Trustee when the value of the
Trust is less than $500,000 ($3,000,000 if the value of the Trust has exceeded
$15,000,000) (the "Minimum Termination Value"). Unitholders will be notified of
any termination. The Trustee may begin to sell Securities in connection with a
Trust termination nine business days before, and no later than, the Mandatory
Termination Date. Approximately thirty days before this date, the Trustee will
notify Unitholders of the termination and provide a form enabling qualified
Unitholders to elect an in kind distribution of Securities. See "Rights of
Unitholders--Redemption of Units". This form must be returned at least five
business days prior to the Mandatory Termination Date. Unitholders will receive
a final cash distribution within a reasonable time after the Mandatory
Termination Date. All distributions will be net of Trust expenses and costs.
Unitholders will receive a final distribution statement following termination.
The Information Supplement contains further information regarding termination of
the Trusts. See "Additional Information".
Limitations on Liabilities. The Sponsor, Evaluator, Supervisor and Trustee
are under no liability 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 is 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 is not be liable for any action taken by it in good faith under
the Trust Agreement. The Trustee is not liable for any taxes or other
governmental charges imposed on the Securities, on it as Trustee under the Trust
Agreement or on a Trust which the Trustee may be required to pay under any
present or future law of the United States of America or of any other taxing
authority having jurisdiction. In addition, the Trust Agreement contains other
customary provisions limiting the liability of the Trustee. The Trustee, Sponsor
and Supervisor may rely on any evaluation furnished by the Evaluator and have no
responsibility for the accuracy thereof. Determinations by the Evaluator shall
be made in good faith upon the basis of the best information available to it.
Sponsor. Van Kampen Funds Inc., a Delaware corporation, is the Sponsor of the
Trust. The Sponsor is an indirect subsidiary of Morgan Stanley Dean Witter & Co.
Van Kampen Funds 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. As of November 30, 1998, the total stockholders' equity of Van Kampen
Funds Inc. was $135,236,000 (audited). The Information Supplement contains
additional information about the Sponsor.
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. Additional information
regarding the Trustee is set forth in the Information Supplement, including the
Trustee's qualifications and duties, its ability to resign, the effect of a
merger involving the Trustee and the Sponsor's ability to remove and replace the
Trustee. See "Additional Information".
Performance Information. The Sponsor may from time to time in its advertising
and sales materials compare the then current estimated returns on the Trusts and
returns over specified time periods on other similar Van Kampen trusts (which
may show performance net of expenses and charges which the Trusts would have
charged) with returns on other taxable investments such as the common stocks
comprising the Dow Jones Industrial Average, the S&P 500, other investment
indices, corporate or U.S. government bonds, bank CDs, money market accounts or
money market funds, or with performance data from Lipper Analytical Services,
Inc., Morningstar Publications, Inc. or various publications, each of which has
characteristics that may differ from those of the Trusts. Information on
percentage changes in the dollar value of Units may be included from time to
time in advertisements, sales literature, reports and other information
furnished to current or prospective Unitholders. Total return figures may not be
averaged and may not reflect deduction of the sales charge, which would decrease
return. No provision is made for any income taxes payable. Past performance may
not be indicative of future results. The Trust portfolios are not managed and
Unit price and return fluctuate with the value of common stocks in the
portfolios, so there may be a gain or loss when Units are sold. As with other
performance data, performance comparisons should not be considered
representative of the Trust's relative performance for any future period.

TAXATION
- --------------------------------------------------------------------------------

The following is a general discussion of certain of the federal income tax
consequences of the purchase, ownership and disposition of the Units of your
Trust. 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 in the Trust 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 Security asset when such income is considered to be received
by the Trust.
2. 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 the date the Unitholder purchase his Units) in order to determine his
initial tax basis for his pro rata portion of each Security held by the Trust.
Unitholders should consult their own tax advisers 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 are 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 Equity 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.
3. 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 such capital 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 Unitholder will be considered to have
received all of the dividends paid on his pro rata portion of each Security when
such dividends are received by the Trust regardless of whether such dividends
are used to pay a portion of a 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. 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 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. 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. Unitholders should consult with their
tax advisers with respect to the limitations on and possible modifications to
the dividends received deduction.
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.
Unitholders should consult with their own tax advisers regarding the
deductibility of Trust expenses.
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. The Internal Revenue Service Restructing and
Reform Act of 1998 (the "1998 Tax Act") provides that for taxpayers other than
corporations, net capital gain (which is defined as net long-term capital gain
over net short-term capital loss for the taxable year) realized from property
(with certain exclusions) is subject to a maximum marginal stated tax rate of
20% (10% in the case of certain taxpayers in the lowest tax bracket). Capital
gain or loss is long-term if the holding period for the asset is more than one
year, and is short-term if the holding period for the asset is one year or less.
The date on which a Unit is acquired (i.e., the "trade date") is excluded for
purposes of determining the holding period of the Unit. Capital gains realized
from assets held for one year or less are taxed at the same rates as ordinary
income.
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 is deemed thereby to have disposed of
his entire pro rata interest in all 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 of loss) and for purposes of
determining the holding period. Unitholders should consult their own tax
advisers with regard to any such constructive sales 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. 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 held 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 in the Securities held by
the Trust. However, if a Unitholder also receives cash in exchange for a
fractional share of such 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.
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 of 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.
Other Matters. 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 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 corporations for a three-year period ending with the close
of its taxable year preceding payment was 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 Securities that
are attributable to foreign corporations may be subject to foreign withholding
taxes and Unitholders should consult their 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 tax 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
of the Trust 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.
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.
Unitholders should consult their tax advisers regarding potential foreign, state
or local taxation with respect to the Units.

TRUST OPERATING EXPENSES
- --------------------------------------------------------------------------------

Compensation of Sponsor, Supervisor and Evaluator. The Sponsor will not
receive any fees in connection with its activities relating to the Trusts.
However, the Supervisor and Evaluator, which are affiliates of the Sponsor, will
receive the annual fee for portfolio supervisory and evaluation services set
forth in the "Fee Table". These fees may exceed the actual costs of providing
these services to the Trusts but at no time will the total amount received for
supervisory and evaluation services rendered to all Van Kampen unit investment
trusts in any calendar year exceed the aggregate cost of providing these
services in that year.
Trustee's Fee. For its services the Trustee will receive the fee from each
Trust set forth in the "Fee Table" (which includes the estimated amount of
miscellaneous Trust expenses). The Trustee benefits to the extent there are
funds 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 each Trust is
expected to result from the use of these funds.
Miscellaneous Expenses. 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 such 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 a Trust and the rights and interests of
Unitholders, (f) indemnification of the Trustee for any loss, liability or
expenses incurred in the administration of a Trust without negligence, bad faith
or wilful misconduct on its part, (g) foreign custodial and transaction fees,
(h) costs associated with liquidating the securities held in a Trust portfolio,
(i) any offering costs incurred after the end of the initial offering period and
(j) expenditures incurred in contacting Unitholders upon termination of a Trust.
Each Trust may pay the expenses of updating its registration statement each
year. Unit investment trust sponsors have historically paid these expenses.
General. During 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 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 on a monthly basis.
The deferred sales charge, fees and expenses are generally paid out of the
Capital Account of the related Trust. When these amounts are paid by or owing to
the Trustee, they are secured by a lien on the related Trust's portfolio. It is
expected that Securities will be sold to pay these amounts which will result in
capital gains or losses to Unitholders. See "Taxation". The Supervisor's,
Evaluator's and Trustee's 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 or, if this
category is not published, in a comparable category.

RISK FACTORS

Price Volatility. Because the Trusts invest in common stocks of U.S. and
foreign companies, you should understand the risks of investing in common stocks
before purchasing Units. These risks include the risk that the financial
condition of the company or the general condition of the stock market may worsen
and the value of the stocks (and therefore Units) will fall. Common stocks are
especially susceptible to general stock market movements. The value of common
stocks often rises or falls rapidly and unpredictably as market confidence and
perceptions of companies change. These perceptions are based on factors
including expectations regarding government economic policies, inflation,
interest rates, economic expansion or contraction, political climates and
economic or banking crises. The value of Units will fluctuate with the value of
the stocks in a Trust and may be more or less than the price you originally paid
for your Units. As with any investment, we cannot guarantee that the performance
of a Trust will be positive over any period of time. Because the Trusts are
unmanaged, the Trustee will not sell stocks in response to market fluctuations
as is common in managed investments. In addition, because some Trusts hold a
relatively small number of stocks, you may encounter greater market risk than in
a more diversified investment.
Dividends. Common stocks represent ownership interests in a company and are
not obligations of the company. Accordingly, common stockholders have a right to
receive payments from the company that is subordinate to the rights of
creditors, bondholders or preferred stockholders of the company. This means that
common stockholders have a right to receive dividends only if a company's board
of directors declares a dividend and the company has provided for payment of all
of its creditors, bondholders and preferred stockholders. If a company issues
additional debt securities or preferred stock, the owners of these securities
will have a claim against the company's assets before common stockholders if the
company declares bankruptcy or liquidates its assets even though the common
stock was issued first. As a result, the company may be less willing or able to
declare or pay dividends on its common stock.
Foreign Stocks. Because certain Trusts invest in foreign common stocks,
they involve additional risks that differ from an investment in domestic stocks.
Investments in foreign securities may involve a greater degree of risk than
those in domestic securities. There is generally less publicly available
information about foreign companies in the form of reports and ratings similar
to those that are published about issuers in the United States. Also, foreign
issuers are generally not subject to uniform accounting, auditing and financial
reporting requirements comparable to those applicable to United States issuers.
With respect to certain foreign countries, there is the possibility of adverse
changes in investment or exchange control regulations, expropriation,
nationalization or confiscatory taxation, limitations on the removal of funds or
other assets of a Trust, political or social instability, or diplomatic
developments which could affect United States investments in those countries.
Moreover, industrial foreign economies may differ favorably or unfavorably from
the United States' economy in terms of growth of gross national product, rate of
inflation, capital reinvestment, resource self-sufficiency and balance of
payments position. Foreign securities markets are generally not as developed or
efficient as those in the United States. While growing in volume, they usually
have substantially less volume than the New York Stock Exchange, and securities
of some foreign issuers are less liquid and more volatile than securities of
comparable United States issuers. Fixed commissions on foreign exchanges are
generally higher than negotiated commissions on United States exchanges. There
is generally less government supervision and regulation of securities exchanges,
brokers and listed issuers than in the United States.
Foreign Currencies. Certain Trusts also involve the risk that fluctuations
in exchange rates between the U.S. dollar and foreign currencies may negatively
affect the value of the stocks. For example, if a foreign stock rose 10% in
price but the U.S. dollar gained 5% against the related foreign currency, a U.S.
investor's return would be reduced to about 5%. This is because the foreign
currency would "buy" fewer dollars or, conversely, a dollar would buy more of
the foreign currency. Many foreign currencies have fluctuated widely against the
U.S. dollar for a variety of reasons such as supply and demand of the currency,
investor perceptions of world or country economies, political instability,
currency speculation by institutional investors, changes in government policies,
buying and selling of currencies by central banks of countries, trade balances
and changes in interest rates. A Trust's foreign currency transactions will be
conducted with foreign exchange dealers acting as principals on a spot (i.e.,
cash) buying basis. These dealers realize a profit based on the difference
between the price at which they buy the currency (bid price) and the price at
which they sell the currency (offer price). The Evaluator will estimate the
currency exchange rates based on current activity in the related currency
exchange markets, however, due to the volatility of the markets and other
factors, the estimated rates may not be indicative of the rate a Trust might
obtain had the Trustee sold the currency in the market at that time.
Liquidity. Whether or not the stocks in a Trust are listed on a stock
exchange, the stocks may delist from the exchange or principally trade in an
over-the-counter market. As a result, the existence of a liquid trading market
could depend on whether dealers will make a market in the stocks. We cannot
guarantee that dealers will maintain a market or that any market will be liquid.
The value of the stocks could fall if trading markets are limited or absent.
Additional Units. The Sponsor may create additional Units of a Trust by
depositing into the Trust additional stocks or cash with instructions to
purchase additional stocks. A cash deposit could result in a dilution of your
investment and anticipated income because of fluctuations in the price of the
stocks between the time of the deposit and the purchase of the stocks and
because the Trust will pay brokerage fees.
Voting. Only the Trustee may sell or vote the stocks in a Trust. While you
may sell or redeem your Units, you may not sell or vote the stocks in your
Trust. The Sponsor will instruct the Trustee how to vote the stocks. The Trustee
will vote the stocks in the same general proportion as shares held by other
shareholders if the Sponsor fails to provide instructions.
Year 2000. The Trusts could be negatively impacted if computer systems used
by the Sponsor, Evaluator, Supervisor or Trustee or other service providers to
the Trusts do not properly process date-related information after January 1,
2000. This is commonly known as the "Year 2000 Problem". The Sponsor, Evaluator,
Supervisor and Trustee are taking steps to address this problem and to obtain
reasonable assurances that other service providers to the Trusts are taking
comparable steps. We cannot guarantee that these steps will be sufficient to
avoid any adverse impact on the Trusts. This problem is expected to impact
corporations to varying degrees based on factors such as industry sector and
degree of technological sophistication. We cannot predict what impact, if any,
this problem will have on the issuers of stocks in the Trusts.
Technology Issuers. The Internet Trust and the Technology Trust are
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 the Technology 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 should be made with an understanding of the characteristics
of the technology industry and the risks 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
obsolescence, cyclical market patterns, evolving industry standards and frequent
new product introductions. The success of the issuers of the Securities depends
in substantial part on 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 developing marketplace.
The market for certain technology products and services may have only
recently begun to develop, is rapidly evolving and is characterized by an
increasing number of market entrants. Additionally, certain technology companies
may have only recently commenced operations or offered equity securities to the
public. Such companies are in the early stage of development and have a limited
operating history on which to analyze future operating results. 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 a Trust a Unitholder will receive an amount greater than or equal
to the Unitholder's initial investment.
Based on trading history, factors such as announcements of new products or
development of new technologies and general 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
and 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 are incorporated into
other related products, certain companies are often highly dependent on the
performance of other computer, electronics and communications companies. 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
form other customers. Similarly, the success of certain 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.

THE TRUSTS

In seeking the Trusts' objectives, the Sponsor considered the ability of
the Securities to outpace inflation. While inflation is currently relatively
low, the United States has historically experienced periods of double-digit
inflation. While the prices of securities will fluctuate, over time securities
have outperformed the rate of inflation, and other less risky investments, such
as government bonds and U.S. Treasury bills. Past performance is, however, no
guarantee of future results.
Investors should note that the above criteria were applied to the
Securities for inclusion in the Trusts as of the Initial Date of Deposit. Should
a Security no longer meet the criteria used for selection for a Trust, such
Security will not as a result thereof be removed from a Trust portfolio.

Stocks have been acknowledged as one of the best ways to stay ahead of
inflation over time. For example, $1 growing at the rate of inflation (as
measured by the Consumer Price Index) would have grown to approximately $9.16
from the beginning of 1926 to the end of 1998. Over the same period $1 invested
in the common stocks comprising the S&P 500 Index, long-term U.S. government
bonds or short-tem U.S. Treasury Bills would have grown to approximately
$2,351.04, $44.18 or $14.96. Source: Ibbotson Associates. These figures do not
take into consideration taxes or any sales charges, commissions or fees that an
investor would incur in connection with these investments. The S&P 500 Index
measures the performance of 500 stocks from 83 industrial groups. U.S. Treasury
bonds are considered long-term investments and are subject to price
fluctuations. The value of long-term bonds decline as interest rates rise. Stock
indices are unmanaged, statistical composites and do not include payment of any
sales charges or fees an investor would pay to purchase the securities they
represent. Furthermore, an investment cannot be made in an index. U.S. Treasury
bills are short-term obligations of the U.S. government that are purchased at a
discount and mature at face value. U.S. government securities are backed by the
full faith and credit of the government. The Consumer Price Index is a
statistical measure of the annual rate of inflation; it is not an investment.
The historical performance of these indices is shown for illustrative purposes
only; it is not meant to forecast, imply or guarantee the future performance of
any particular investment vehicle or the Trust. Securities in which the Trust
invests will be different from those in these indices. Common stocks involve
greater risks than government bonds and CDs, as they are more volatile and have
greater potential for loss of principal.

The Internet Trust and the Morgan Stanley High-Technology 35 Index Trust may
offer growth potential based on the following factors. Some expect the internet
audience to increase from 100 million by the end of 1998 to 320 million by 2002.
The percentage of World Wide Web users making purchases online may grow from 26%
in 1997 to 40% in 2002. Some expect World Wide Web commerce to increase from
$2.6 billion in 1996 to $400 billion by 2002.

SPONSOR INFORMATION

Van Kampen Funds Inc., a Delaware corporation, is the Sponsor of the Trust.
The Sponsor is an indirect subsidiary of Van Kampen Investments Inc. Van Kampen
Investments Inc. is a wholly owned subsidiary of MSAM Holdings II, Inc., which
in turn is a wholly owned subsidiary of Morgan Stanley Dean Witter & Co.
("MSDW").
MSDW, 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.
Van Kampen Funds 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. As of November 30, 1998, the total stockholders' equity of Van Kampen
Funds Inc. was $135,236,000 (audited). (This paragraph relates only to the
Sponsor and not to the Trust or to any other Series thereof. The information is
included herein only for the purpose of informing investors as to the financial
responsibility of the Sponsor and its ability to carry out its contractual
obligations. More detailed financial information will be made available by the
Sponsor upon request.)
As of March 31, 1999, the Sponsor and its Van Kampen affiliates managed or
supervised approximately $75 billion of investment products. The Sponsor and its
Van Kampen affiliates managed $64 billion of assets, consisting of $36.6 billion
for 50 open-end mutual funds, $19.5 billion for 39 closed-end funds and $8.2
billion for 106 institutional accounts. The Sponsor has also deposited more than
3,200 unit trusts amounting to approximately $35.4 billion of assets. All of Van
Kampen'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 or evaluation services at cost for approximately $13.4
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 INFORMATION

The Trustee is The Bank of New York, a trust company organized under the
laws of New York. The Bank of New York has its unit investment trust division
offices at 101 Barclay Street, New York, New York 10286 (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 each Trust. Such
records shall include the name and address of, and the number of Units of each
Trust held by, every Unitholder. Such books and records shall be open to
inspection by any Unitholder at all reasonable times during the usual business
hours. The Trustee shall make such annual or other reports as may from time to
time be required under any applicable state or federal statute, rule or
regulation. The Trustee is required to keep a certified copy or duplicate
original of the Trust Agreement on file in its office available for inspection
at all reasonable times during the usual business hours by any Unitholder,
together with a current list of the 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.

TRUST TERMINATION

A Trust may be liquidated at any time by consent of Unitholders
representing 66 2/3% of the Units of such Trust then outstanding or by the
Trustee when the value of the Securities owned by a Trust, as shown by any
evaluation, is less than $500,000 ($3,000,000 if the value of the Trust has
exceeded $15,000,000). A Trust will be liquidated by the Trustee in the event
that a sufficient number of Units of such Trust not yet sold are tendered for
redemption by the Sponsor, so that the net worth of such Trust would be reduced
to less than 40% of the value of the Securities at the time they were deposited
in such 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 held thereunder, but in
no event will it continue beyond the Mandatory Termination Date.
Commencing during the period beginning nine business days prior to, and no
later than, the Mandatory Termination Date, 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 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 of the appropriate Trust and in the case of a
Trust will include with such notice a form to enable Unitholders owning 1,000 or
more Units to request an in kind distribution of the U.S.-traded Securities. 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 prior business day if a holiday) the Trustee will
deliver each requesting Unitholder's pro rata number of whole shares of the
U.S.-traded Securities in a Trust 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 in a Trust with 1,000 or
more Units not requesting an in kind distribution 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 appropriate Trust 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 in a Trust 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 of each Trust his pro rata share of the balance of the Income
and Capital Accounts of such Trust.
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.
