INVESTMENT SUMMARY
------------------


                              INVESTMENT OBJECTIVE

  The trust seeks to provide above average total return primarily through
capital appreciation.  There is no assurance the trust will achieve its
objective.

                          PRINCIPAL INVESTMENT STRATEGY

  The trust seeks to achieve its objective by investing in a portfolio of
stocks of companies headquartered in the United States and deriving a
substantial portion of their revenues worldwide that we<F1>* believe are
involved in aspects of the transformation of consumer behavior and a shift in
how people transact purchases.  Today, shopping has become easier as innovations
in electronics and information technology provide consumers access to a wide
range of products from the convenience of almost anywhere and the ease of using
their smart phones and tablets.  Consumers can fulfill desires spontaneously
without going to brick and mortar stores.  Consumers shop online using smart
phones and tablets, connect wirelessly from almost anywhere, are able to
purchase almost any product online, pay by credit cards and have products
delivered to their doorsteps.

  From these companies involved in aspects of this shift in how people transact
purchases, securities were selected for the trust's portfolio by analyzing
factors including expected market dominance over the next three to five years,
relative size within industry sectors based on market capitalization, steadiness
of past earnings growth rates and revenue growth, strength of earnings and
revenue projects, balance sheet strength, valuation and levels of cash holdings.

                                 PRINCIPAL RISKS

  As with all investments, you can lose money by investing in this trust.  The
trust also might not perform as well as you expect.  This can happen for reasons
such as these:

*  SECURITY PRICES WILL FLUCTUATE.  The value of your investment may fall over
   time.

*  THE FINANCIAL CONDITION OF AN ISSUER MAY WORSEN OR ITS CREDIT RATINGS MAY
   DROP, RESULTING IN A REDUCTION IN THE VALUE OF YOUR UNITS.  This may occur
   at any point in time, including during the primary offering period.

*  THE ISSUER OF A SECURITY MAY BE UNWILLING OR UNABLE TO MAKE DIVIDEND PAYMENTS
   IN THE FUTURE.  This may reduce the level of dividends the trust receives
   which would reduce your income and cause the value of your units to fall.

*  THE TRUST IS CONSIDERED TO BE CONCENTRATED IN SECURITIES ISSUED BY COMPANIES
   IN THE INFORMATION TECHNOLOGY SECTOR.  Negative developments in the
   information technology sector will affect the value of your investment more
   than would be the case in a more diversified investment.

*  WE DO NOT ACTIVELY MANAGE THE PORTFOLIO.  Except in limited circumstances,
   the trust will generally hold, and continue to buy, shares of the same
   securities even if their market value declines.

  The initial sales fee is the difference between the total sales fee (maximum
of 3.95% of the unit offering price) and the sum of the remaining deferred sales
fee and the total creation and development fee.  The deferred sales fee is
fixed at $0.245 per unit and is paid in three monthly installments beginning
____________ 20, 2013.  The creation and development fee is fixed at $0.05 per
unit and is paid at the end of the initial offering period (anticipated to be
six months).

                                     EXAMPLE

  This example helps you compare the cost of this trust with other unit trusts
and mutual funds.  In the example we assume that the expenses do not change and
that the trust's annual return is 5%.  Your actual returns and expenses will
vary.  Based on these assumptions, you would pay these expenses for every
$10,000 you invest in the trust:

          1 year                           $_____
          2 years (life of trust)          $_____

  These amounts are the same regardless of whether you sell your investment at
the end of a period or continue to hold your investment.

                                                        Investment Summary     5


-----------------------------
UNDERSTANDING YOUR INVESTMENT
-----------------------------


                                HOW TO BUY UNITS

  You can buy units of the trust on any business day the New York Stock
Exchange is open by contacting your financial professional.  Unit prices are
available daily on the Internet at WWW.AAMPORTFOLIOS.COM.  The public offering
price of units includes:

  *  the net asset value per unit plus

  *  organization costs plus

  *  the sales fee.

  The "net asset value per unit" is the value of the securities, cash and other
assets in the trust reduced by the liabilities of the trust divided by the total
units outstanding.  We often refer to the public offering price of units as the
"offer price" or "purchase price."  The offer price will be effective for all
orders received prior to the close of regular trading on the New York Stock
Exchange (normally 4:00 p.m. Eastern time).  If we receive your order prior to
the close of regular trading on the New York Stock Exchange or authorized
financial professionals receive your order prior to that time and properly
transmit the order to us by the time that we designate, then you will receive
the price computed on the date of receipt.  If we receive your order after the
close of regular trading on the New York Stock Exchange, if authorized financial
professionals receive your order after that time or if orders are received by
such persons and are not transmitted to us by the time that we designate, then
you will receive the price computed on the date of the next determined offer
price provided that your order is received in a timely manner on that date.  It
is the responsibility of the authorized financial professional to transmit the
orders that they receive to us in a timely manner.  Certain broker-dealers may
charge a transaction or other fee for processing unit purchase orders.

  VALUE OF THE SECURITIES.  We determine the value of the securities as of the
close of regular trading on the New York Stock Exchange on each day that
exchange is open.  We generally determine the value of securities using the last
sale price for securities traded on a national securities exchange.  For this
purpose, the trustee provides us closing prices from a reporting service
approved by us.  In some cases we will price a security based on the last asked
or bid price in the over-the-counter market or by using other recognized pricing
methods.  We will only do this if a security is not principally traded on a
national securities exchange or if the market quotes are unavailable or
inappropriate.

  We determined the initial prices of the securities shown under "Portfolio" in
this prospectus as described above at the close of regular trading on the New
York Stock Exchange on the business day before the date of this prospectus.  On
the first day we sell units we will compute the unit price as of the close of
regular trading on the New York Stock Exchange or the time the registration
statement filed with the Securities and Exchange Commission becomes effective,
if later.

  ORGANIZATION COSTS.  During the initial offering period, part of the value of
the securities represents an amount that will pay the costs of creating your
trust.  These costs include the costs of preparing the registration statement
and legal documents, federal and state registration fees, the initial fees and
expenses of the trustee and the initial audit.  Your trust will sell securities
to reimburse us for these costs at the end of the initial offering period or
after six months, if earlier.  The value of your units will decline when the
trust pays these costs.


6     Understanding Your Investment


  TRANSACTIONAL SALES FEE.  You pay a fee in connection with purchasing units.
We refer to this fee as the "transactional sales fee."  The transactional sales
fee has both an initial and a deferred component and equals 3.45% of the public
offering price per unit based on a $10 public offering price per unit.  This
percentage amount of the transactional sales fee is based on the unit price on
the trust's inception date.  The transactional sales fee equals the difference
between the total sales fee and the creation and development fee.  As a result,
the percentage and dollar amount of the transactional sales fee will vary as the
public offering price per unit varies.  The transactional sales fee does not
include the creation and development fee which is described under "Expenses."

  The maximum sales fee equals 3.95% of the public offering price per unit at
the time of purchase.  You pay the initial sales fee at the time you buy units.
The initial sales fee is the difference between the total sales fee percentage
(maximum of 3.95% of the public offering price per unit) and the sum of the
remaining fixed dollar deferred sales fee and the total fixed dollar creation
and development fee.  The initial sales fee will be approximately 1.00% of the
public offering price per unit depending on the public offering price per unit.
The deferred sales fee is fixed at $0.245 per unit.  Your trust pays the
deferred sales fee in equal monthly installments as described on page 3.  If you
redeem or sell your units prior to collection of the total deferred sales fee,
you will pay any remaining deferred sales fee upon redemption or sale of your
units.

  If you purchase units after the last deferred sales fee payment has been
assessed, the secondary market sales fee is equal to 3.95% of the public
offering price and does not include deferred payments.

  MINIMUM PURCHASE.  The minimum amount you can purchase of the trust appears
on page 3 under "Essential Information", but such amounts may vary depending on
your selling firm.

  REDUCING YOUR SALES FEE.  We offer a variety of ways for you to reduce the
fee you pay.  It is your financial professional's responsibility to alert us of
any discount when you order units.  Except as expressly provided herein, you may
not combine discounts.  Since the deferred sales fee and the creation and
development fee are fixed dollar amounts per unit, your trust must charge these
fees per unit regardless of any discounts.  However, if you are eligible to
receive a discount such that your total sales fee is less than the fixed dollar
amounts of the deferred sales fee and the creation and development fee, we will
credit you the difference between your total sales fee and these fixed dollar
fees at the time you buy units.

  Large Purchases.  You can reduce your sales fee by increasing the size of
your investment:

      IF YOU PURCHASE:        YOUR FEE WILL BE:
     ------------------------------------------

     Less than $50,000             3.95%
     $50,000 - $99,999             3.70
     $100,000 - $249,999           3.45
     $250,000 - $499,999           3.10
     $500,000 - $999,999           2.95
     $1,000,000 or more            2.45

  We apply these fees as a percent of the public offering price per unit at the
time of purchase.  The breakpoints will be adjusted to take into consideration
purchase orders stated in dollars which cannot be completely fulfilled due to
the requirements that only whole units be issued.

  You aggregate initial offering period unit orders submitted by the same
person for units of any of the trusts we sponsor on any single day from any one
broker-dealer to qualify for a purchase level.  If you purchase initial offering
period


                                             Understanding Your Investment     7


units that qualify for the fee account or rollover/exchange discount described
below and also purchase additional initial offering period units on a single day
from the same broker-dealer that do not qualify for the fee account or
rollover/exchange discount, you aggregate all initial offering period units
purchased for purposes of determining the applicable breakpoint level in the
table above on the additional units, but such additional units will not qualify
for the fee account or rollover/exchange discount described below.  Secondary
market unit purchases are not aggregated with initial offering period unit
purchases for purposes of determining the applicable breakpoint level.  You can
also include these orders as your own for purposes of this aggregation:

  *  orders submitted by your spouse or children (including step-children)
     under 21 years of age living in the same household and

  *  orders submitted by your trust estate or fiduciary accounts.

  The discounts described above apply only to initial offering period
purchases.

  Fee Accounts.  Investors may purchase units through registered investment
advisers, certified financial planners or registered broker-dealers who in each
case either charge investor accounts ("Fee Accounts") periodic fees for
brokerage services, financial planning, investment advisory or asset management
services, or provide such services in connection with an investment account for
which a comprehensive "wrap fee" charge ("Wrap Fee") is imposed.  You should
consult your financial advisor to determine whether you can benefit from these
accounts.  To purchase units in these Fee Accounts, your financial advisor must
purchase units designated with one of the Fee Account CUSIP numbers, if
available.  Please contact your financial advisor for more information.  If
units of the trust are purchased for a Fee Account and the units are subject to
a Wrap Fee in such Fee Account (i.e., the trust is "Wrap Fee Eligible") then
investors may be eligible to purchase units of the trust in these Fee Accounts
that are not subject to the transactional sales fee but will be subject to the
creation and development fee that is retained by the sponsor.  For example, this
table illustrates the sales fee you will pay as a percentage of the initial $10
public offering price per unit (the percentage will vary with the unit price).

  Initial sales fee                0.00%
  Deferred sales fee               0.00%
                                  -------
    Transactional sales fee        0.00%
                                  =======
  Creation and development fee     0.50%
                                  -------
    Total sales fee                0.50%
                                  =======

  This discount applies only during the initial offering period.  Certain Fee
Account investors may be assessed transaction or other fees on the purchase
and/or redemption of units by their broker-dealer or other processing
organizations for providing certain transaction or account activities.  We
reserve the right to limit or deny purchases of units in Fee Accounts by
investors or selling firms whose frequent trading activity is determined to be
detrimental to the trust.

  Employees.  We waive the transactional sales fee for purchases made by
officers, directors and employees (and immediate family members) of the sponsor
and its affiliates.  These purchases are not subject to the transactional sales
fee but will be subject to the creation and development fee.  We also waive a
portion of the sales fee for purchases made by officers, directors and employees
(and immediate family members) of selling firms.  These purchases are made at
the public offering price per unit less the applicable regular dealer


8     Understanding Your Investment


concession.  Immediate family members for the purposes of this section include
your spouse, children (including step-children) under the age of 21 living in
the same household, and parents (including step-parents).  These discounts apply
to initial offering period and secondary market purchases.  All employee
discounts are subject to the policies of the related selling firm, including but
not limited to, householding policies or limitations.  Only officers, directors
and employees (and their immediate family members) of selling firms that allow
such persons to participate in this employee discount program are eligible for
the discount.

  Rollover/Exchange Option.  We waive a portion of the sales fee on units of
the trust offered in this prospectus if you buy your units with redemption or
termination proceeds from any unit investment trusts (regardless of sponsor).
The discounted public offering price per unit for these transactions is equal to
the regular public offering price per unit less 1.00%.  However, if you invest
redemption or termination proceeds of $500,000 or more in units of the trust,
the maximum sales fee on your units will be limited to the maximum sales fee for
the applicable amount invested in the table under "Large Purchases" above.  To
qualify for this discount, the termination or redemption proceeds used to
purchase units of the trust offered in this prospectus must be derived from a
transaction that occurred within 30 calendar days of your purchase of units of
the trust offered in this prospectus.  In addition, the discount will only be
available for investors that utilize the same broker-dealer (or a different
broker-dealer with appropriate notification) for both the unit purchase and the
transaction resulting in the receipt of the termination or redemption proceeds
used for the unit purchase.  You may be required to provide appropriate
documentation or other information to your broker-dealer to evidence your
eligibility for this sales fee discount.

  Please note that if you purchase units of the trust in this manner using
redemption proceeds from trusts which assess the amount of any remaining
deferred sales fee at redemption, you should be aware that any deferred sales
fee remaining on these units will be deducted from those redemption proceeds.
These discounts apply only to initial offering period purchases.

  Dividend Reinvestment Plan.  We do not charge any sales fee when you reinvest
distributions from your trust into additional units of the trust.  This sales
fee discount applies to initial offering period and secondary market purchases.
Since the deferred sales fee and the creation and development fee are fixed
dollar amounts per unit, your trust must charge these fees per unit regardless
of this discount.  If you elect the distribution reinvestment plan, we will
credit you with additional units with a dollar value sufficient to cover the
amount of any remaining deferred sales fee and creation and development fee that
will be collected on such units at the time of reinvestment.  The dollar value
of these units will fluctuate over time.

  RETIREMENT ACCOUNTS.  The portfolio may be suitable for purchase in tax-
advantaged retirement accounts.  You should contact your financial professional
about the accounts offered and any additional fees imposed.

                             HOW TO SELL YOUR UNITS

  You can sell or redeem your units on any business day the New York Stock
Exchange is open by contacting your financial professional.  Unit prices are
available daily on the Internet at WWW.AAMPORTFOLIOS.COM or through your
financial professional.  The sale and redemption price of units is equal to the
net asset value per unit, provided that you will not pay any remaining creation
and development fee or organization costs if


                                             Understanding Your Investment     9


you sell or redeem units during the initial offering period.  The sale and
redemption price is sometimes referred to as the "liquidation price."  You pay
any remaining deferred sales fee when you sell or redeem your units.  Certain
broker-dealers may charge a transaction or other fee for processing unit
redemption or sale requests.

  SELLING UNITS.  We may maintain a secondary market for units.  This means
that if you want to sell your units, we may buy them at the current net asset
value, provided that you will not pay any remaining creation and development fee
or organization costs if you sell units during the initial offering period.  We
may then resell the units to other investors at the public offering price or
redeem them for the redemption price.  Our secondary market repurchase price is
the same as the redemption price.  Certain broker-dealers might also maintain a
secondary market in units.  You should contact your financial professional for
current repurchase prices to determine the best price available.  We may
discontinue our secondary market at any time without notice.  Even if we do not
make a market, you will be able to redeem your units with the trustee on any
business day for the current redemption price.

  REDEEMING UNITS.  You may also redeem your units directly with the trustee,
The Bank of New York Mellon, on any day the New York Stock Exchange is open.
The redemption price that you will receive for units is equal to the net asset
value per unit, provided that you will not pay any remaining creation and
development fee or organization costs if you redeem units during the initial
offering period.  You will pay any remaining deferred sales fee at the time you
redeem units.  You will receive the net asset value for a particular day if the
trustee receives your completed redemption request prior to the close of regular
trading on the New York Stock Exchange.  Redemption requests received by
authorized financial professionals prior to the close of regular trading on the
New York Stock Exchange that are properly transmitted to the trustee by the time
designated by the trustee, are priced based on the date of receipt.  Redemption
requests received by the trustee after the close of regular trading on the New
York Stock Exchange, redemption requests received by authorized financial
professionals after that time or redemption requests received by such persons
that are not transmitted to the trustee until after the time designated by the
trustee, are priced based on the date of the next determined redemption price
provided they are received in a timely manner by the trustee on such date.  It
is the responsibility of authorized financial professionals to transmit
redemption requests received by them to the trustee so they will be received in
a timely manner.  If your request is received after that time or is incomplete
in any way, you will receive the next net asset value computed after the trustee
receives your completed request.

  If you redeem your units, the trustee will generally send you a payment for
your units no later than seven days after it receives all necessary
documentation (this will usually only take three business days).  The only time
the trustee can delay your payment is if the New York Stock Exchange is closed
(other than weekends or holidays), the Securities and Exchange Commission
determines that trading on that exchange is restricted or an emergency exists
making sale or evaluation of the securities not reasonably practicable, and for
any other period that the Securities and Exchange Commission permits.

  You can request an in-kind distribution of the securities underlying your
units if you tender at least 2,500 units for redemption (or such other amount as
required by your financial professional's


10     Understanding Your Investment


firm).  This option is generally available only for securities traded and held
in the United States.  The trustee will make any in-kind distribution of
securities by distributing applicable securities in book entry form to the
account of your financial professional at Depository Trust Company.  You will
receive whole shares of the applicable securities and cash equal to any
fractional shares.  You may not request this option in the last 30 days of your
trust's life.  We may discontinue this option at any time without notice.

  EXCHANGE OPTION.  You may be able to exchange your units for units of our
other unit trusts at a reduced sales fee.  You can contact your financial
professional for more information about trusts currently available for
exchanges.  Before you exchange units, you should read the prospectus carefully
and understand the risks and fees.  You should then discuss this option with
your financial professional to determine whether your investment goals have
changed, whether current trusts suit you and to discuss tax consequences.  We
may discontinue this option upon sixty days notice.

                                  DISTRIBUTIONS

  MONTHLY DISTRIBUTIONS.  Your trust generally pays distributions of its net
investment income along with any excess capital on each monthly distribution
date to unitholders of record on the preceding record date, provided that the
total cash held for distribution equals at least 0.1% of the trust's net asset
value as determined under the trust agreement.  The record and distribution
dates are shown under "Essential Information" in the "Investment Summary"
section of this prospectus.  In some cases, your trust might pay a special
distribution if it holds an excessive amount of cash pending distribution.  For
example, this could happen as a result of a merger or similar transaction
involving a company whose stock is in your portfolio.  The amount of your
distributions will vary from time to time as companies change their dividends or
trust expenses change.

  The issuers in the trust's portfolio make dividend payments at various times
during the year.  When the trust receives dividends from issuers, the trustee
credits the dividends to the trust's accounts.  Because the trust does not
necessarily receive dividends from the underlying issuers at a constant rate
throughout the year, the trust's income distributions to unitholders will
fluctuate from month to month.

  ESTIMATED ANNUAL DISTRIBUTIONS.  The estimated net annual distributions are
shown under "Essential Information" in the "Investment Summary" section of this
prospectus.  We generally base the estimate of the income the trust may receive
on annualizing the most recent ordinary dividend declared by an issuer (or
adding the most recent interim and final dividends declared for certain foreign
issuers) or on scheduled income payments.  However, dividend conventions for
certain companies and/or certain countries differ from those typically used in
the United States and in certain instances, dividends paid or declared over
several years or other periods were used to estimate annual distributions.  Due
to this and various other factors, actual income payments received by the trust
will most likely differ from the most recent annualized dividends or scheduled
income payments.  The actual net annual distributions you will receive will vary
with changes in the trust's fees and expenses, in income payments received and
with the sale of securities.  The estimated net annual distributions for
subsequent years are expected to be less than estimated distributions for the
first year because a portion of the securities included in the trust portfolio
will be sold during the first year to pay for organization


                                            Understanding Your Investment     11


costs, the creation and development fee and the deferred sales fee.

  REPORTS.  The trustee or your financial professional will make available to
you a statement showing income and other receipts of your trust for each
distribution.  Each year the trustee will also provide an annual report on your
trust's activity and certain tax information.  You can request copies of
security evaluations to enable you to complete your tax forms and audited
financial statements for your trust, if available.

                                INVESTMENT RISKS

  All investments involve risk.  This section describes the main risks that can
impact the value of the securities in your portfolio.  You should understand
these risks before you invest.  If the value of the securities falls, the value
of your units will also fall.  We cannot guarantee that your trust will achieve
its objective or that your investment return will be positive over any period.

  MARKET RISK is the risk that the value of the securities in your trust will
fluctuate.  This could cause the value of your units to fall below your original
purchase price.  Market value fluctuates in response to various factors.  These
can include changes in interest rates, inflation, the financial condition of a
security's issuer, perceptions of the issuer, or ratings on a security.  Even
though we supervise your portfolio, you should remember that we do not manage
your portfolio.  Your trust will not sell a security solely because the market
value falls as is possible in a managed fund.

  DIVIDEND PAYMENT RISK is the risk that an issuer of a security is unwilling
or unable to pay income on a security.  Stocks represent ownership interests in
the issuers and are not obligations of the issuers.  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.

  CONCENTRATION RISK is the risk that the value of your trust is more
susceptible to fluctuations based on factors that impact a particular industry
because the portfolio concentrates in companies within that industry.  A
portfolio "concentrates" in an industry when securities issued by companies in a
particular industry make up 25% or more of the portfolio.  As the target index
is rebalanced over time, the trust could be concentrated in other industries at
certain times.

  The trust concentrates in stocks of companies in the INFORMATION TECHNOLOGY
sector. Technology companies are generally subject to the risks of rapidly
changing technologies; short product life cycles; fierce competition; aggressive
pricing; frequent introduction of new or enhanced products; the loss of patent,
copyright and trademark protections; cyclical market patterns; evolving industry
standards; and frequent new product introductions. Technology companies may be
smaller and less experienced companies, with limited product lines, markets or
financial resources. Technology company stocks have experienced extreme price
and volume fluctuations that are often unrelated to their operating performance,
and have lately experienced significant market declines in their share values.
Also, the stocks of many internet companies have exceptionally high price-to-
earnings ratios with little or no earnings histories.

  LEGISLATION/LITIGATION.  From time to time, various legislative initiatives
are proposed in the


12     Understanding Your Investment


United States and abroad which may have a negative impact on certain of the
companies represented in the trust.  In addition, litigation regarding any of
the issuers of the securities or of the industries represented by these issuers
may negatively impact the share prices of these securities.  No one can predict
what impact any pending or threatened litigation will have on the share prices
of the securities.

  LIQUIDITY RISK is the risk that the value of a security will fall if trading
in the security is limited or absent.  No one can guarantee that a liquid
trading market will exist for any security.

  NO FDIC GUARANTEE.  An investment in the 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.

                               HOW THE TRUST WORKS

  YOUR TRUST.  Your trust is a unit investment trust registered under the
Investment Company Act of 1940.  We created the trust under a trust agreement
between Advisors Asset Management, Inc. (as depositor/sponsor, evaluator and
supervisor) and The Bank of New York Mellon (as trustee).  To create your trust,
we deposited securities with the trustee (or contracts to purchase securities
along with an irrevocable letter of credit or other consideration to pay for the
securities).  In exchange, the trustee delivered units of your trust to us.
Each unit represents an undivided interest in the assets of your trust.  These
units remain outstanding until redeemed or until your trust terminates.  At the
close of the New York Stock Exchange on the trust's inception date, 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 the trust will
increase or decrease to the extent of any adjustment.

  CHANGING YOUR PORTFOLIO.  Your trust is not a managed fund.  Unlike a managed
fund, we designed your portfolio to remain relatively fixed.  Your trust will
generally buy and sell securities:

  *  to pay expenses,

  *  to issue additional units or redeem units,

  *  in limited circumstances to protect the trust,

  *  as permitted by the trust agreement.

  When your trust sells securities, the composition and diversity of the
securities in the portfolio may be altered.  If a public tender offer has been
made for a security or a merger, acquisition or similar transaction has been
announced affecting a security, the trustee may either sell the security or
accept a tender offer if the supervisor determines that the action is in the
best interest of unitholders.  The trustee will distribute any cash proceeds to
unitholders.  If your trust receives securities or other property, it will
either hold the securities or property in the portfolio or sell the securities
or property and distribute the proceeds.

  We will increase the size of your trust as we sell units.  When we create
additional units, we will seek to replicate the existing portfolio.  When your
trust buys securities, it may pay brokerage or other acquisition fees.  You
could experience a dilution of your investment because of these fees and
fluctuations in security prices between the time we create units and the time
your trust buys the securities.  When your trust buys or sells securities, we
may direct that it place orders with and pay brokerage commissions to


                                            Understanding Your Investment     13


brokers that sell units or are affiliated with us, your trust or the trustee.

  Pursuant to an exemptive order, your trust may be able to purchase securities
from other trusts that we sponsor when we create additional units.  Your trust
may also be able to sell securities to other trusts that we sponsor to satisfy
unit redemption, pay deferred sales charges or expenses, in connection with
periodic tax compliance or in connection with the termination of your trust.
The exemption may enable each trust to eliminate commission costs on these
transactions.  The price for those securities will be the closing price on the
sale date on the exchange where the securities are principally traded as
certified by us to the trustee.

  AMENDING THE TRUST AGREEMENT.  The sponsor and the trustee can change the
trust agreement without your consent to correct any provision that may be
defective or to make other provisions that will not materially adversely affect
your interest (as determined by the sponsor and the trustee).  We cannot change
this agreement to reduce your interest in your trust without your consent.
Investors owning two-thirds of the units in your trust may vote to change this
agreement.

  TERMINATION OF YOUR TRUST.  Your trust will terminate on the termination date
set forth under "Essential Information" in the "Investment Summary" section of
this prospectus.  The trustee may terminate your trust early if the value of the
trust is less than 40% of the original value of the securities in the trust at
the time of deposit.  At this size, the expenses of your trust may create an
undue burden on your investment.  Investors owning two-thirds of the units in
your trust may also vote to terminate the trust early.  The trustee will
liquidate the trust in the event that a sufficient number of units not yet sold
to the public are tendered for redemption so that the net worth of the trust
would be reduced to less than 40% of the value of the securities at the time
they were deposited in the trust.  If this happens, we will refund any sales
charge that you paid.

  The trustee will notify you of any termination and sell any remaining
securities.  The trustee will send your final distribution to you within a
reasonable time following liquidation of all the securities after deducting
final expenses.  Your termination distribution may be less than the price you
originally paid for your units.

  THE SPONSOR.  The sponsor of the trust is Advisors Asset Management, Inc.  We
are a broker-dealer specializing in providing trading and support services to
broker-dealers, registered representatives, investment advisers and other
financial professionals.  Our headquarters are located at 18925 Base Camp Road,
Monument, Colorado 80132.  You can contact our unit investment trust division at
8100 East 22nd Street North, Building 800, Suite 102, Wichita, Kansas 67226 or
by using the contacts listed on the back cover of this prospectus.  AAM is a
registered broker-dealer and investment adviser, a member of the Financial
Industry Regulatory Authority, Inc. (FINRA) and Securities Investor Protection
Corporation (SIPC) and a registrant of the Municipal Securities Rulemaking Board
(MSRB).  If we fail to or cannot perform our duties as sponsor or become
bankrupt, the trustee may replace us, continue to operate your trust without a
sponsor, or terminate your trust.

  We and your trust have adopted a code of ethics requiring our employees who
have access to information on trust transactions to report personal securities
transactions.  The purpose of the code is to avoid potential conflicts of
interest and


14     Understanding Your Investment


to prevent fraud, deception or misconduct with respect to your trust.

  The sponsor or an affiliate may use the list of securities in the trust in
its independent capacity (which may include acting as an investment adviser or
broker-dealer) and distribute this information to various individuals and
entities.  The sponsor or an affiliate may recommend or effect transactions in
the securities.  This may also have an impact on the price your trust pays for
the securities and the price received upon unit redemption or trust termination.
The sponsor may act as agent or principal in connection with the purchase and
sale of securities, including those held by the trust, and may act as a
specialist market maker in the securities.  The sponsor may also issue reports
and make recommendations on the securities in the trust.  The sponsor or an
affiliate may have participated in a public offering of one or more of the
securities in the trust.  The sponsor, an affiliate or their employees may have
a long or short position in these securities or related securities.  An officer,
director or employee of the sponsor or an affiliate may be an officer or
director for the issuers of the securities.

  THE TRUSTEE.  The Bank of New York Mellon is the trustee of your trust.  Its
principal unit investment trust division office is located at 2 Hanson Place,
12th Floor, Brooklyn, New York 11217.  You can contact the trustee by calling
the telephone number on the back cover of this prospectus or by writing to its
unit investment trust office.  We may remove and replace the trustee in some
cases without your consent.  The trustee may also resign by notifying us and
investors.

  HOW WE DISTRIBUTE UNITS.  We sell units to the public through broker-dealers
and other firms.  We pay part of the sales fee to these distribution firms when
they sell units.  During the initial offering period, the distribution fee (the
broker-dealer concession or agency commission) for broker-dealers and other
firms is as follows:

       TRANSACTION             CONCESSION OR
         AMOUNT:             AGENCY COMMISSION:
     ------------------------------------------

     Less than $50,000             3.10%
     $50,000 - $99,999             2.85
     $100,000 - $249,999           2.60
     $250,000 - $499,999           2.30
     $500,000 - $999,999           2.20
     $1,000,000 or more            1.75

  We apply these concessions or agency commissions as a percent of the public
offering price per unit at the time of the transaction.  The broker-dealer
concession or agency commission is 65% of the sales fee for secondary market
sales.  For transactions involving unitholders of other unit investment trusts
who use their redemption or termination proceeds to purchase units of the trust,
the distribution fee is 2.15% of the public offering price per unit.  No
distribution fee is paid to broker-dealers or other selling firms in connection
with unit sales in Fee Accounts subject to a Wrap Fee.

  Broker-dealers and other firms that sell units of certain unit investment
trusts for which AAM acts as sponsor are eligible to receive additional
compensation for volume sales.  The sponsor offers two separate volume
concession structures for certain trusts that are referred to as "Volume
Concession A" and "Volume Concession B."  The trust offered in this prospectus
is a Volume Concession A trust.  Broker-dealers and other firms that sell units
of any Volume Concession A trust are eligible to receive the additional
compensation described below.  Such payments will be in addition to the regular
concessions paid to firms


                                            Understanding Your Investment     15


as set forth in the applicable trust's prospectus. The additional concession is
based on total initial offering period sales of all Volume Concession A trusts
during a calendar quarter as set forth in the following table:

       INITIAL OFFERING PERIOD SALES                  VOLUME
          DURING CALENDAR QUARTER                   CONCESSION
     ---------------------------------------------------------

     Less than $10,000,000                            0.000%
     $10,000,000 but less than $25,000,000            0.050
     $25,000,000 but less than $50,000,000            0.100
     $50,000,000 but less than $75,000,000            0.110
     $75,000,000 but less than $100,000,000           0.120
     $100,000,000 but less than $250,000,000          0.125
     $250,000,000 but less than $500,000,000          0.135
     $500,000,000 or more                             0.150

  This volume concession will be paid on units of all Volume Concession A
trusts sold in the initial offering period, except as described below.  For a
trust to be eligible for this additional Volume Concession A compensation for
calendar quarter sales, the trust's prospectus must include disclosure related
to this additional Volume Concession A compensation; a trust is not eligible for
this additional Volume Concession A compensation if the prospectus for such
trust does not include disclosure related to this additional Volume Concession A
compensation.  Broker-dealer firms will not receive additional compensation
unless they sell at least $10.0 million of units of Volume Concession A trusts
during a calendar quarter.  For example, if a firm sells $9.5 million of units
of Volume Concession A trusts in the initial offering period during a calendar
quarter, the firm will not receive any additional compensation with respect to
such trusts.  Once a firm reaches a particular breakpoint during a quarter, the
firm will receive the stated volume concession on all initial offering period
sales of Volume Concession A trusts during the applicable quarter.  For example,
if a firm sells $12.5 million of units of Volume Concession A trusts in the
initial offering period during a calendar quarter, the firm will receive
additional compensation of 0.05% of $12.5 million and if a firm sells $27.0
million of units of Volume Concession A trusts in the initial offering period
during a calendar quarter, the firm will receive additional compensation of
0.100% of $27.0 million.

  In addition, dealer firms will not receive volume concessions on the sale of
units which are not subject to a transactional sales charge.  However, such
sales will be included in determining whether a firm has met the sales level
breakpoints for volume concessions.  Secondary market sales of all unit trusts
are excluded for purposes of these volume concessions.  We will pay these
amounts out of our own assets within a reasonable time following each calendar
quarter.

  Any sales fee discount is borne by the broker-dealer or selling firm out of
the distribution fee.  We reserve the right to change the amount of concessions
or agency commissions from time to time.

  We currently provide, at our own expense and out of our own profits,
additional compensation and benefits to broker-dealers who sell units of this
trust and our other products.  This compensation is intended to result in
additional sales of our products and/or compensate broker-dealers and financial
advisors for past sales.  A number of factors are considered in determining
whether to pay these additional amounts.  Such factors may include, but are not
limited to, the level or type of services provided by the intermediary, the
level or expected level of sales of our products by the intermediary or its
agents, the placing of our products on a preferred or recommended product list
and access to an intermediary's personnel.  We may make these payments for
marketing, promotional or related expenses,


16     Understanding Your Investment


including, but not limited to, expenses of entertaining retail customers and
financial advisors, advertising, sponsorship of events or seminars, obtaining
information about the breakdown of unit sales among an intermediary's
representatives or offices, obtaining shelf space in broker-dealer firms and
similar activities designed to promote the sale of our products.  We make such
payments to a substantial majority of intermediaries that sell our products.  We
may also make certain payments to, or on behalf of, intermediaries to defray a
portion of their costs incurred for the purpose of facilitating unit sales, such
as the costs of developing or purchasing trading systems to process unit trades.
Payments of such additional compensation described in this paragraph and the
volume concessions described above, some of which may be characterized as
"revenue sharing," may create an incentive for financial intermediaries and
their agents to sell or recommend our products, including this trust, over other
products.  These arrangements will not change the price you pay for your units.

  We generally register units for sale in various states in the U.S.  We do not
register units for sale in any foreign country.  This prospectus does not
constitute an offer of units in any state or country where units cannot be
offered or sold lawfully.  We may reject any order for units in whole or in
part.

  We may gain or lose money when we hold units in the primary or secondary
market due to fluctuations in unit prices.  The gain or loss is equal to the
difference between the price we pay for units and the price at which we sell or
redeem them.  We may also gain or lose money when we deposit securities to
create units.  The amount of our profit or loss on the initial deposit of
securities into the trust is shown in the "Notes to Portfolio."

                                      TAXES

  This section summarizes some of the main U.S. federal income tax consequences
of owning units of the trust.  This section is current as of the date of this
prospectus.  Tax laws and interpretations change frequently, and these summaries
do not describe all of the tax consequences to all taxpayers.  For example,
these summaries generally do not describe your situation if you are a
corporation, a non-U.S. person, a broker/dealer, or other investor with special
circumstances.  In addition, this section does not describe your state, local or
foreign tax consequences.

  This federal income tax summary is based in part on the advice and opinion of
counsel to the sponsor.  The Internal Revenue Service could disagree with any
conclusions set forth in this section.  In addition, our counsel was not asked
to review, and has not reached a conclusion with respect to the federal income
tax treatment of the assets to be deposited in the trust.  This may not be
sufficient for you to use for the purpose of avoiding penalties under federal
tax law.

  As with any investment, you should seek advice based on your individual
circumstances from your own tax advisor.

  ASSETS OF THE TRUST.  The trust is expected to hold shares of stock in
corporations (the "Stocks") that are treated as equity for federal income tax
purposes.  It is possible that the trust will also hold other assets, including
assets that are treated differently for federal income tax purposes from those
described above, in which case you will have federal income tax consequences
different from or in addition to those described in this section.  All of the
assets held by the trust constitute the "Trust Assets."  Neither our counsel nor
we have analyzed the proper federal income tax treatment


                                            Understanding Your Investment     17


of the Trust Assets and thus neither our counsel nor we have reached a
conclusion regarding the federal income tax treatment of the Trust Assets.

  TRUST STATUS.  If the trust is at all times operated in accordance with the
documents establishing the trust and certain requirements of federal income tax
law are met, the trust will not be taxed as a corporation for federal income tax
purposes.  As a unit owner, you will be treated as the owner of a pro rata
portion of each of the Trust Assets, and as such you will be considered to have
received a pro rata share of income (e.g., dividends and capital gains, if any)
from each Trust Asset when such income would be considered to be received by you
if you directly owned the Trust Assets.  This is true even if you elect to have
your distributions reinvested into additional units.  In addition, the income
from Trust Assets that you must take into account for federal income tax
purposes is not reduced by amounts used to pay sales charges or trust expenses.
Under the "Health Care and Education Reconciliation Act of 2010," income from
the trust may also be subject to a new 3.8 percent "medicare tax"  imposed for
taxable years beginning after 2012.  This tax will generally apply to your net
investment income if your adjusted gross income exceeds certain threshold
amounts, which are $250,000 in the case of married couples filing joint returns
and $200,000 in the case of single individuals.

  YOUR TAX BASIS AND INCOME OR LOSS UPON DISPOSITION.  If your trust disposes
of Trust Assets, you will generally recognize gain or loss.  If you dispose of
your units or redeem your units for cash, you will also generally recognize gain
or loss.  To determine the amount of this gain or loss, you must subtract your
tax basis in the related Trust Assets from your share of the total amount
received in the transaction.  You can generally determine your initial tax basis
in each Trust Asset by apportioning the cost of your units, including sales
charges, among the Trust Assets ratably according to their values on the date
you acquire your units.  In certain circumstances, however, you may have to
adjust your tax basis after you acquire your units (for example, in the case of
certain dividends that exceed a corporation's accumulated earnings and profits,
as discussed below).

  If you are an individual, the maximum marginal federal tax rate for net
capital gain is generally 20%  for taxpayers in the 39.6% tax bracket, 15% for
taxpayers in the 25%, 28%, 33% and 35% tax brackets and 0% for taxpayers in the
10% and 15% tax brackets.

  Net capital gain equals net long-term capital gain minus net short-term
capital loss for the taxable year.  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.  You must exclude the date you
purchase your units to determine your holding period.  The tax rates for capital
gains realized from assets held for one year or less are generally the same as
for ordinary income.  The Internal Revenue Code, however, treats certain capital
gains as ordinary income in special situations.

  DIVIDENDS FROM STOCKS.  Certain dividends received with respect to the Stocks
may qualify to be taxed at the same rates that apply to net capital gain (as
discussed above), provided certain holding period requirements are satisfied.

  DIVIDENDS RECEIVED DEDUCTION.  Generally, a domestic corporation owning units
in a trust may be eligible for the dividends received deduction with respect to
such unit owner's pro rata portion of certain types of dividends received by the
trust.  However, a corporation generally will not be entitled to the dividends
received deduction


18     Understanding Your Investment


with respect to dividends from most foreign corporations.

  IN-KIND DISTRIBUTIONS.  Under certain circumstances as described in this
prospectus, you may request an In-Kind Distribution of Trust Assets when you
redeem your units or at your trust's termination.  By electing to receive an In-
Kind Distribution, you will receive Trust Assets plus, possibly, cash.  You will
not recognize gain or loss if you only receive whole Trust Assets in exchange
for the identical amount of your pro rata portion of the same Trust Assets held
by your trust.  However, if you also receive cash in exchange for a Trust Asset
or a fractional portion of a Trust Asset, you will generally recognize gain or
loss based on the difference between the amount of cash you receive and your tax
basis in such Trust Asset or fractional portion.

  ROLLOVERS AND EXCHANGES.  If you elect to have your proceeds from your trust
rolled over into a future trust, it is considered a sale for federal income tax
purposes and any gain on the sale will be treated as a capital gain, and any
loss will be treated as a capital loss.  However, any loss you incur in
connection with the exchange of your units of your trust for units of the next
series will generally be disallowed with respect to this deemed sale and
subsequent deemed repurchase, to the extent the two trusts have substantially
identical Trust Assets under the wash sale provisions of the Internal Revenue
Code.

  LIMITATIONS ON THE DEDUCTIBILITY OF TRUST EXPENSES.  Generally, for federal
income tax purposes, you must take into account your full pro rata share of your
trust's income, even if some of that income is used to pay trust expenses.  You
may deduct your pro rata share of each expense paid by your trust to the same
extent as if you directly paid the expense.  You may be required to treat some
or all of the expenses of your trust as miscellaneous itemized deductions.
Individuals may only deduct certain miscellaneous itemized deductions to the
extent they exceed 2% of adjusted gross income.  Some individuals may also be
subject to further limitations on the amount of their itemized deductions,
depending on their income.

  FOREIGN INVESTORS, TAXES AND INVESTMENTS.  Distributions by your trust that
are treated as U.S. source income (e.g., dividends received on Stocks of
domestic corporations) will generally be subject to U.S. income taxation and
withholding in the case of Units held by nonresident alien individuals, foreign
corporations or other non-U.S. persons, subject to any applicable treaty.  If
you are a foreign investor (i.e., an investor other than a U.S. citizen or
resident or a U.S. corporation, partnership, estate or trust), you may not be
subject to U.S. federal income taxes, including withholding taxes, on some or
all of the income from your trust or on any gain from the sale or redemption of
your Units, provided that certain conditions are met.  You should consult your
tax advisor with respect to the conditions you must meet in order to be exempt
for U.S. tax purposes.  Distributions in respect of units after December 31,
2013 may be subject to a U.S. withholding tax of 30% in the case of
distributions to (i) certain non-U.S. financial institutions that have not
entered into an agreement with the U.S. Treasury to collect and disclose certain
information and are not resident in a jurisdiction that has entered into such an
agreement with the U.S. Treasury and (ii) certain other non-U.S. entities that
do not provide certain certifications and information about the entity's U.S.
owners.  Dispositions of units by such persons may be subject to such
withholding after December 31, 2016.  You should also consult your tax advisor
with respect to other U.S. tax withholding and reporting requirements.


                                            Understanding Your Investment     19


  Some distributions by your trust may be subject to foreign withholding taxes.
Any income withheld will still be treated as income to you.  Under the grantor
trust rules, you are considered to have paid directly your share of any foreign
taxes that are paid.  Therefore, for U.S. tax purposes, you may be entitled to a
foreign tax credit or deduction for those foreign taxes.

  If any U.S. investor is treated as owning directly or indirectly 10 percent
or more of the combined voting power of the stock of a foreign corporation, and
all U.S. shareholders of that corporation collectively own more than 50 percent
of the vote or value of the stock of that corporation, the foreign corporation
may be treated as a controlled foreign corporation (CFC).  If you own 10 percent
or more of a CFC (through the trust and in combination with your other
investments) or possibly if the trust owns 10 percent or more of a CFC, you will
be required to include certain types of the CFC's income in your taxable income
for federal income tax purposes whether or not such income is distributed to the
trust or to you.

  A foreign corporation will generally be treated as a passive foreign
investment company (PFIC) if 75 percent or more of its income is passive income
or if 50 percent or more of its assets are held to produce passive income.  If
the trust purchases shares in a PFIC, you may be subject to U.S. federal income
tax on a portion of certain distributions or on gains from the disposition of
such shares at rates that were applicable in prior years and any gain may be
recharacterized as ordinary income that is not eligible for the lower net
capital gains tax rate.  Additional charges in the nature of interest may also
be imposed on you.  Certain elections may be available with respect to PFICs
that would limit these consequences.  However, these elections would require you
to include certain income of the PFIC in your taxable income even if not
distributed to the trust or to you, or require you to annually recognize as
ordinary income any increase in the value of the shares of the PFIC, thus
requiring you to recognize income for federal income tax purposes in excess of
your actual distributions from PFICs and proceeds from dispositions of PFIC
stock during a particular year.  Dividends paid by PFICs will not be eligible to
be taxed at the net capital gains tax rate.

  NEW YORK TAX STATUS.  Under the existing income tax laws of the State and
City of New York, your trust will not be taxed as a corporation subject to the
New York state franchise tax or the New York City general corporation tax.  You
should consult your tax advisor regarding potential foreign, state or local
taxation with respect to your units.

                                    EXPENSES

  Your trust will pay various expenses to conduct its operations.  The "Fees
and Expenses" section of the "Investment Summary" in this prospectus shows the
estimated amount of these expenses.

  The sponsor will receive a fee from your trust for creating and developing
the trust, including determining the trust's objectives, policies, composition
and size, selecting service providers and information services and for providing
other similar administrative and ministerial functions.  This "creation and
development fee" is a charge of $0.05 per unit.  The trustee will deduct this
amount from your trust's assets as of the close of the initial offering period.
No portion of this fee is applied to the payment of distribution expenses or as
compensation for sales efforts.  This fee will not be deducted from proceeds
received upon a repurchase, redemption


20     Understanding Your Investment


or exchange of units before the close of the initial public offering period.

  Your trust will pay a fee to the trustee for its services.  The trustee also
benefits when it holds cash for your trust in non-interest bearing accounts.
Your trust will reimburse us as supervisor, evaluator and sponsor for providing
portfolio supervisory services, for evaluating your portfolio and for providing
bookkeeping and administrative services.  Our reimbursements may exceed the
costs of the services we provide to your trust but will not exceed the costs of
services provided to all of our unit investment trusts in any calendar year.
All of these fees may adjust for inflation without your approval.

  Your trust will also pay its general operating expenses.  Your trust may pay
expenses such as trustee expenses (including legal and auditing expenses),
various governmental charges, fees for extraordinary trustee services, costs of
taking action to protect your trust, costs of indemnifying the trustee and the
sponsor, legal fees and expenses, expenses incurred in contacting you and costs
incurred to reimburse the trustee for advancing funds to meet distributions.
Your trust may pay the costs of updating its registration statement each year.
The trustee will generally pay trust expenses from distributions received on the
securities but in some cases may sell securities to pay trust expenses.

                                     EXPERTS

  LEGAL MATTERS.  Chapman and Cutler, LLP acts as counsel for the trust and has
given an opinion that the units are validly issued.  Dorsey & Whitney LLP acts
as counsel for the trustee.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

UNITHOLDERS
ADVISORS DISCIPLINED TRUST 1057

We have audited the accompanying statement of financial condition, including the
trust portfolio on pages 4 and 5, of Advisors Disciplined Trust 1057, as of
April __, 2013, the initial date of deposit.  The statement of financial
condition is the responsibility of the trust's sponsor.  Our responsibility is
to express an opinion on this statement of financial condition based on our
audit.

We conducted our audit in accordance with auditing standards of the Public
Company Accounting Oversight Board (United States).  Those standards require
that we plan and perform the audit to obtain reasonable assurance about whether
the statement of financial condition is free of material misstatement.  The
trust is not required to have, nor were we engaged to perform an audit of its
internal control over financial reporting.  Our audit included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the trust's internal control over
financial reporting.  Accordingly, we express no such opinion.  An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the statement of financial condition, assessing the accounting
principles used and significant estimates made by the sponsor, as well as
evaluating the overall statement of financial condition presentation.  Our
procedures included confirmation with The Bank of New York Mellon, trustee, of
cash or an irrevocable letter of credit deposited for the purchase of securities
as shown in the statement of financial condition as of April __, 2013.  We
believe that our audit of the statement of financial condition provides a
reasonable basis for our opinion.

In our opinion, the statement of financial condition referred to above presents
fairly, in all material respects, the financial position of Advisors Disciplined
Trust 1057 as of April __, 2013, in conformity with accounting principles
generally accepted in the United States of America.

<FN>
(1)  Aggregate cost of the securities is based on the closing sale price
     evaluations as determined by the evaluator.
(2)  Cash or an irrevocable letter of credit has been deposited with the trustee
     covering the funds (aggregating $200,000) necessary for the purchase of
     securities in the trust represented by purchase contracts.
(3)  A portion of the public offering price represents an amount sufficient to
     pay for all or a portion of the costs incurred in establishing and offering
     the trust.  These costs have been estimated at $0.05 per unit for the
     trust.  A distribution will be made as of the earlier of the close of the
     initial offering period or six months following the trust's inception date
     to an account maintained by the trustee from which this obligation of the
     investors will be satisfied.  To the extent the actual organization costs
     are greater than the estimated amount, only the estimated organization
     costs added to the public offering price will be reimbursed to the sponsor
     and deducted from the assets of the trust.
(4)  The total sales fee consists of an initial sales fee, a deferred sales fee
     and a creation and development fee.  The initial sales fee is equal to the
     difference between the maximum sales fee and the sum of the remaining
     deferred sales fee and the total creation and development fee.  On the
     inception date, the total sales fee is 3.95% of the public offering price
     per unit.  The deferred sales fee is equal to $0.245 per unit and the
     creation and development fee is equal to $0.05 per unit.
(5)  The aggregate cost to investors includes the applicable sales fee assuming
     no reduction of sales fees.

GENERAL INFORMATION

     Each trust is one of a series of separate unit investment trusts created
under the name Advisors Disciplined Trust and registered under the Investment
Company Act of 1940.  Each trust was created as a common law trust on the
inception date described in the prospectus under the laws of the state of
New York.  Each trust was created under a trust agreement among Advisors Asset
Management, Inc. (as sponsor, evaluator and supervisor) and The Bank of New York
Mellon (as trustee).

     When your trust was created, the sponsor delivered to the trustee
securities or contracts for the purchase thereof for deposit in the trust and
the trustee delivered to the sponsor documentation evidencing the ownership of
units of the trust.  At the close of the New York Stock Exchange on the trust's
inception date, the number of units may be adjusted so that the public offering
price per unit equals $10.  The number of units, fractional interest of each
unit in the trust and estimated interest distributions per unit will increase or
decrease to the extent of any adjustment.  Additional units of each trust may be
issued from time to time by depositing in the trust additional securities (or
contracts for the purchase thereof together with cash or irrevocable letters of
credit) or cash (including a letter of credit or the equivalent) with
instructions to purchase additional securities.  As additional units are issued
by a trust as a result of the deposit of additional securities by the sponsor,
the aggregate value of the securities in the trust will be increased and the
fractional undivided interest in the trust represented by each unit will be
decreased.  The sponsor may continue to make additional deposits of securities
into a trust, provided that such additional deposits will be in amounts, which
will generally maintain the existing relationship among the shares of the
securities in such trust.  Thus, although additional units will be issued, each
unit will generally continue to represent the same number of shares of each
security.  If the sponsor deposits cash to purchase additional securities,
existing and new 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 trust will pay any associated brokerage fees.

     The trustee has not participated in the selection of the securities
deposited in the trust and has no responsibility for the composition of the
trust portfolio.

     Each unit initially offered represents an undivided interest in the related
trust.  To the extent that any units are redeemed by the trustee or additional
units are issued as a result of additional securities being deposited by the
sponsor, the fractional undivided interest in a trust represented by each
unredeemed unit will increase or decrease accordingly, although the actual
interest in such trust represented by such fraction will remain unchanged.
Units will remain outstanding until redeemed upon tender to the trustee by
unitholders, which may include the sponsor, or until the termination of the
trust agreement.

     A trust consists of (a) the securities listed under "Portfolio" in the
prospectus 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 accounts of the trust.
Neither the sponsor nor the trustee shall be liable in any way for any failure
in any of the securities.  However, should any contract for the purchase of any
of the securities initially


                                       -2-


deposited in a trust fail, the sponsor will, unless substantially all of the
moneys held in the trust to cover such purchase are reinvested in substitute
securities in accordance with the trust agreement, refund the cash and sales fee
attributable to such failed contract to all unitholders on the next distribution
date.

INVESTMENT OBJECTIVE AND POLICIES
     The trust seeks to provide above average total return primarily through
capital appreciation.  There is, of course, no guarantee that the trust will
achieve its objective.  The prospectus provides additional information regarding
the trust's objective and investment strategy.

     The trust is a unit investment trust and is not an "actively managed" fund.
Traditional methods of investment management for a managed fund typically
involve frequent changes in a portfolio of securities on the basis of economic,
financial and market analysis.  The portfolio of a trust, however, will not be
actively managed and therefore the adverse financial condition of an issuer will
not necessarily require the sale of its securities from a portfolio.

     The sponsor may not alter the portfolio of a trust by the purchase, sale or
substitution of securities, except in special circumstances as provided in the
trust agreement.  Thus, the assets of a trust will generally remain unchanged
under normal circumstances.  The trust agreement provides that the sponsor may
(but need not) direct the trustee to dispose of a security in certain events
such as the issuer having defaulted on the payment on any of its outstanding
obligations or the price of a security has declined to such an extent or other
such credit factors exist so that in the opinion of the supervisor the retention
of such securities would be detrimental to the trust.  If a public tender offer
has been made for a security or a merger or acquisition has been announced
affecting a security, the trustee may either sell the security or accept a
tender offer for cash if the supervisor determines that the sale or tender is in
the best interest of unitholders.  The trustee will distribute any excess cash
proceeds to unitholders.  Pursuant to the trust agreement and with limited
exceptions, the trustee may sell any securities or other properties acquired in
exchange for securities such as those acquired in connection with a merger or
other transaction.  If offered such new or exchanged securities or property
other than cash, trustee shall generally reject the offer.  However, in the
event such securities or property are nonetheless acquired by the trust, they
may be accepted for deposit in a trust and either sold by the trustee or held in
a trust pursuant to the direction of the sponsor.

     The trustee may sell securities, designated by the supervisor, from a trust
for the purpose of redeeming units of such trust tendered for redemption and the
payment of expenses.

     Proceeds from the sale of securities (or any securities or other property
received by a trust in exchange for securities) are credited to the Capital
Account of a trust for distribution to unitholders or to meet redemptions.
Except for failed securities and as provided herein, in the prospectus or in the
trust agreement, the acquisition by a trust of any securities other than the
portfolio securities is prohibited.


                                       -3-


     Because certain of the securities in certain of the trusts may from time to
time under certain circumstances be sold or otherwise liquidated and because the
proceeds from such events will be distributed to unitholders and will not be
reinvested, no assurance can be given that a trust will retain for any length of
time its present size and composition.  Neither the sponsor nor the trustee
shall be liable in any way for any default, failure or defect in any security.
In the event of a failure to deliver any security that has been purchased for a
trust under a contract ("Failed Securities"), the sponsor is authorized under
the trust agreement to direct the trustee to acquire other securities
("Replacement Securities") to make up the original corpus of such trust.

     The Replacement Securities must be purchased within 20 days after delivery
of the notice that a contract to deliver a security will not be honored and the
purchase price may not exceed the amount of funds reserved for the purchase of
the Failed Securities.  The Replacement Securities must be equity securities of
the type selected for the trust and must not adversely affect the federal income
tax status of the trust.  Whenever a Replacement Security is acquired for a
trust, the trustee shall notify all unitholders of the trust of the acquisition
of the Replacement Security and shall, on the next monthly distribution date
which is more than 30 days thereafter, make a pro rata distribution of the
amount, if any, by which the cost to the trust of the Failed Security exceeded
the cost of the Replacement Security.  Once all of the securities in a trust are
acquired, the trustee will have no power to vary the investments of the trust,
i.e., the trustee will have no managerial power to take advantage of market
variations to improve a unitholder's investment.

     If the right of limited substitution described in the preceding paragraphs
is not utilized to acquire Replacement Securities in the event of a failed
contract, the sponsor will refund the sales fee attributable to such Failed
Securities to all unitholders of the trust and the trustee will distribute the
cash attributable to such Failed Securities not more than 30 days after the date
on which the trustee would have been required to purchase a Replacement
Security.  In addition, unitholders should be aware that, at the time of receipt
of such cash, they may not be able to reinvest such proceeds in other securities
at a return equal to or in excess of the return which such proceeds would have
earned for unitholders of such trust.

     In the event that a Replacement Security is not acquired by a trust, the
income for such trust may be reduced.

     To the best of the sponsor's knowledge, there is no litigation pending as
of the trust's inception in respect of any security that might reasonably be
expected to have a material adverse effect on the trust.  At any time after the
trust's inception, litigation may be instituted on a variety of grounds with
respect to the securities.  The sponsor is unable to predict whether any such
litigation may be instituted, or if instituted, whether such litigation might
have a material adverse effect on the trust.  The sponsor and the trustee shall
not be liable in any way for any default, failure or defect in any security.

RISK FACTORS

     MARKET RISK.  Because the trust invests in stocks, you should understand
the risks of investing in 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


                                       -4-


of the stocks (and therefore units) will fall.  Stocks are especially
susceptible to general stock market movements.  The value of 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 the 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 the trust will be
positive over any period of time.  Because the trust is 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.  Stocks represent ownership interests in a company and are not
obligations of the company.  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.

     INFORMATION TECHNOLOGY. The trust may invest significantly in information
technology companies. Information technology companies generally include
companies involved in the development, design, manufacture and sale of computers
and peripherals, software and services, data networking and communications
equipment, internet access and information providers, semiconductors and
semiconductor equipment and other related products, systems and services. The
market for these products, especially those specifically related to the
internet, may be characterized by rapidly changing technology, product
obsolescence, cyclical markets, evolving industry standards and frequent new
product introductions. The success of companies in this sector depends, in
substantial part, on the timely and successful introduction of new products. An
unexpected change in one or more of the technologies affecting a company's
products or in the market for products based on a particular technology could
have a material adverse effect on an issuer's operating results. Furthermore,
there can be no assurance that any particular company will be able to respond in
a timely manner to compete in the rapidly developing marketplace.

     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 high-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. Such market volatility may adversely affect the
market price of shares of these companies. Some key components of certain
products of technology issuers are currently available only from single sources.


                                       -5-


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

     Many technology companies rely on a combination of patents, copyrights,
trademarks and trade secret laws to establish and protect their proprietary
rights in their products and technologies. There can be no assurance that the
steps taken to protect proprietary rights will be adequate to prevent
misappropriation of technology or that competitors will not independently
develop technologies that are substantially equivalent or superior to an
issuer's technology. In addition, due to the increasing public use of the
internet, it is possible that other laws and regulations may be adopted to
address issues such as privacy, pricing, characteristics, and quality of
internet products and services. The adoption of any such laws could have a
material adverse impact on the issuers of securities in the trust.

     Like many areas of technology, the semiconductor business environment is
highly competitive, notoriously cyclical and subject to rapid and often
unanticipated change. Recent industry downturns have resulted, in part, from
weak pricing, persistent overcapacity, slowdown in Asian demand and a shift in
retail personal computer sales toward the low-end segment. Industry growth is
dependent upon several factors, including: the rate of global economic
expansion; demand for products such as personal computers and networking and
communications equipment; excess productive capacity and the resultant effect on
pricing; and the rate of growth in the market for low-priced personal computers.

     Legislative proposals concerning healthcare are proposed in Congress from
time to time.  These proposals span a wide range of topics, including cost and
price controls (which might include a freeze on the prices of prescription
drugs), national health insurance incentives for competition in the provision of
healthcare services, tax incentives and penalties related to healthcare
insurance premiums and promotion of prepaid healthcare plans.  The sponsor is
unable to predict the effect of any of these proposals, if enacted, on the
issuers of securities in your trust.

     ADDITIONAL DEPOSITS.  The trust agreement authorizes the sponsor to
increase the size of a trust and the number of units thereof by the deposit of
additional securities, or cash (including a letter of credit or the equivalent)
with instructions to purchase additional securities, in such trust


                                       -6-


and the issuance of a corresponding number of additional units.  In connection
with these deposits, existing and new 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 a trust will pay the associated
brokerage fees and other acquisition costs.

ADMINISTRATION OF THE TRUST

     DISTRIBUTIONS TO UNITHOLDERS.  Income received by a trust is credited by
the trustee to the Income Account for the trust.  All other receipts are
credited by the trustee to a separate Capital Account for the trust.  The
trustee will normally distribute any income received by a trust on each
distribution date or shortly thereafter to unitholders of record on the
preceding record date.  Unitholders will receive an amount substantially equal
to their pro rata share of the available balance of the Income Account of the
trust.  All distributions will be net of applicable expenses.  There is no
assurance that any actual distributions will be made since all dividends
received may be used to pay expenses.  In addition, excess amounts from the
Capital Account of a trust, if any, will be distributed on each distribution
date or shortly thereafter to unitholders of record on the preceding record
date.  The trustee is not required to make a distribution from the Income
Account or the Capital Account unless the total cash held for distribution
equals at least 0.1% of the trust's net asset value as determined under the
trust agreement.  Proceeds received from the disposition of any of the
securities after a record date and prior to the following distribution date will
be held in the Capital Account and not distributed until the next distribution
date applicable to the Capital Account.  The trustee shall be required to make a
distribution from the Capital Account if the cash balance on deposit therein
available for distribution shall be sufficient to distribute at least $1.00 per
unit.  The trustee is not required to pay interest on funds held in the Capital
or Income Accounts (but may itself earn interest thereon and therefore benefits
from the use of such funds).

     The distribution to the unitholders as of each record date will be made on
the following distribution date or shortly thereafter and shall consist of an
amount substantially equal to the unitholders' pro rata share of the available
balance of the Income Account of the trust after deducting estimated expenses.
Because dividends are not received by a trust at a constant rate throughout the
year, such distributions to unitholders are expected to fluctuate.  Persons who
purchase units will commence receiving distributions only after such person
becomes a record owner.  A person will become the owner of units, and thereby a
unitholder of record, on the date of settlement provided payment has been
received.  Notification to the trustee of the transfer of units is the
responsibility of the purchaser, but in the normal course of business the
selling broker-dealer provides such notice.

     The trustee will periodically deduct from the Income Account of a trust
and, to the extent funds are not sufficient therein, from the Capital Account of
a trust amounts necessary to pay the expenses of the trust.  The trustee also
may withdraw from said accounts such amounts, if any, as it deems necessary to
establish a reserve for any governmental charges payable out of a trust.
Amounts so withdrawn shall not be considered a part of a trust's assets until
such time as the trustee shall return all or any part of such amounts to the
appropriate accounts.  In addition, the


                                       -7-


trustee may withdraw from the Income and Capital Accounts of a trust such
amounts as may be necessary to cover redemptions of units.

     DISTRIBUTION REINVESTMENT.  Unitholders may reinvest distributions into
additional units of their trust without a sales fee.  Your trust will pay any
deferred sales fee and creation and development fee per unit regardless of any
sales fee discounts.  However, if you are eligible to receive a discount such
that the sales fee you must pay is less than the applicable deferred sales fee
and creation and development fee, you will be credited the difference between
your sales fee and the deferred sales fee and the creation and development fee
at the time you buy your units.  Accordingly, if you reinvest distributions into
additional units of your trust, you will be credited the amount of any remaining
deferred sales fee and creation and development fee on such units at the time of
reinvestment.

     STATEMENTS TO UNITHOLDERS.  With each distribution, the trustee will
furnish to each unitholder a statement of the amount of income and the amount of
other receipts, if any, which are being distributed, expressed in each case as a
dollar amount per unit.

     The accounts of a trust are required to be audited annually, at the related
trust's expense, by independent public accountants designated by the sponsor,
unless the sponsor determines that such an audit would not be in the best
interest of the unitholders of the trust.  The accountants' report will be
furnished by the trustee to any unitholder upon written request.  Within a
reasonable period of time after the end of each calendar year, the trustee shall
furnish to each person who at any time during the calendar year was a unitholder
of a trust a statement, covering the calendar year, setting forth for the trust:

     (A)  As to the Income Account:

          (1)  the amount of income received on the securities (including income
               received as a portion of the proceeds of any disposition of
               securities);

          (2)  the amounts paid for purchases of replacement securities or for
               purchases of securities otherwise pursuant to the trust
               agreement, if any, and for redemptions;

          (3)  the deductions, if any, from the Income Account for payment into
               the Reserve Account;

          (4)  the deductions for applicable taxes and fees and expenses of the
               trustee, the depositor, the evaluator, the supervisor, counsel,
               auditors and any other expenses paid by the trust;

          (5)  the amounts reserved for purchases of contract securities, for
               purchases made pursuant to replace failed contract securities or
               for purchases of securities otherwise pursuant to the trust
               agreement, if any;


                                       -8-


          (6)  the deductions for payment of the depositor's expenses of
               maintaining the registration of the trust units, if any;

          (7)  the aggregate distributions to unitholders; and

          (8)  the balance remaining after such deductions and distributions,
               expressed both as a total dollar amount and as a dollar amount
               per unit outstanding on the last business day of such calendar
               year;

     (B)  As to the Capital Account:

          (1)  the net proceeds received due to sale, maturity, redemption,
               liquidation or disposition of any of the securities, excluding
               any portion thereof credited to the Income Account;

          (2)  the amount paid for purchases of replacement securities or for
               purchases of securities otherwise pursuant to the trust
               agreement, if any, and for redemptions;

          (3)  the deductions, if any, from the Capital Account for payments
               into the Reserve Account;

          (4)  the deductions for payment of applicable taxes and fees and
               expenses of the trustee, the depositor, the evaluator, the
               supervisor, counsel, auditors and any other expenses paid by the
               trust;

          (5)  the deductions for payment of the depositor's expenses of
               organizing the trust;

          (6)  the amounts reserved for purchases of contract securities, for
               purchases made pursuant to replace failed contract securities or
               for purchases of securities otherwise pursuant to the trust
               agreement, if any;

          (7)  the deductions for payment of deferred sales fee and creation and
               development fee, if any;

          (8)  the deductions for payment of the depositor's expenses of
               maintaining the registration of the trust units, if any;

          (9)  the aggregate distributions to unitholders; and

          (10) the balance remaining after such distributions and deductions,
               expressed both as a total dollar amount and as a dollar amount
               per unit outstanding on the last business day of such calendar
               year; and

     (C)  the following information:


                                       -9-


          (1)  a list of the securities held as of the last business day of such
               calendar year and a list which identifies all securities sold or
               other securities acquired during such calendar year, if any;

          (2)  the number of units outstanding on the last business day of such
               calendar year;

          (3)  the unit value based on the last trust evaluation of such trust
               made during such calendar year; and

          (4)  the amounts actually distributed during such calendar year from
               the Income and Capital Accounts, separately stated, expressed
               both as total dollar amounts and as dollar amounts per unit
               outstanding on the record dates for such distributions.

     RIGHTS OF UNITHOLDERS.  A unitholder may at any time tender units to the
trustee for redemption.  The death or incapacity of any unitholder will not
operate to terminate a trust nor entitle legal representatives or heirs to claim
an accounting or to bring any action or proceeding in any court for partition or
winding up of a trust.  No unitholder shall have the right to control the
operation and management of a trust in any manner, except to vote with respect
to the amendment of the trust agreement or termination of a trust.

     AMENDMENT AND TERMINATION.  The trust agreement may be amended from time to
time by the sponsor and trustee or their respective successors, without the
consent of any of the unitholders, (i) to cure any ambiguity or to correct or
supplement any provision which may be defective or inconsistent with any other
provision contained in the trust agreement, (ii) to make such other provision in
regard to matters or questions arising under the trust agreement as shall not
materially adversely affect the interests of the unitholders or (iii) to make
such amendments as may be necessary (a) for the trust to continue to qualify as
a regulated investment company for federal income tax purposes if the trust has
elected to be taxed as such under the United States Internal Revenue Code of
1986, as amended, or (b) to prevent the trust from being deemed an association
taxable as a corporation for federal income tax purposes if the trust has not
elected to be taxed as a regulated investment company under the United States
Internal Revenue Code of 1986, as amended.  The trust agreement may not be
amended, however, without the consent of all unitholders then outstanding, so as
(1) to permit, except in accordance with the terms and conditions thereof, the
acquisition hereunder of any securities other than those specified in the
schedules to the trust agreement or (2) to reduce the percentage of units the
holders of which are required to consent to certain of such amendments.  The
trust agreement may not be amended so as to reduce the interest in a trust
represented by units without the consent of all affected unitholders.  Except
for the amendments, changes or modifications described above, neither the
sponsor nor the trustee may consent to any other amendment, change or
modification of the trust agreement without the giving of notice and the
obtaining of the approval or consent of unitholders representing at least 66
2/3% of the units then outstanding of the affected trust.  No amendment may
reduce the aggregate percentage of units the holders of which are required to
consent to any amendment, change or modification of the trust agreement without
the consent of the unitholders of all of the units then outstanding of the
affected trust and in no event may any


                                      -10-


amendment be made which would (1) alter the rights to the unitholders as against
each other, (2) provide the trustee with the power to engage in business or
investment activities other than as specifically provided in the trust
agreement, (3) adversely affect the tax status of the trust for federal income
tax purposes or result in the units being deemed to be sold or exchanged for
federal income tax purposes or (4) unless the trust has elected to be taxed as a
regulated investment company for federal income tax purposes, result in a
variation of the investment of unitholders in the trust.  The trustee will
notify unitholders of the substance of any such amendment.

     The trust agreement provides that a trust shall terminate upon the
liquidation, redemption or other disposition of the last of the securities held
in the trust but in no event is it to continue beyond the mandatory termination
date.  If the value of a trust shall be less than the applicable minimum value
stated in the prospectus (generally 40% of the total value of securities
deposited in the trust during the initial offering period), the trustee may, in
its discretion, and shall, when so directed by the sponsor, terminate the trust.
A trust may be terminated at any time by the holders of units representing 66
2/3% of the units thereof then outstanding.  In addition, the sponsor may
terminate a trust if it is based on a security index and the index is no longer
maintained.  A trust will be liquidated by the trustee in the event that a
sufficient number of units of the trust not yet sold are tendered for redemption
by the sponsor, so that the net worth of the trust would be reduced to less than
40% of the value of the securities at the time they were deposited in the trust.
If a trust is liquidated because of the redemption of unsold units by the
sponsor, the sponsor will refund to each purchaser of units the entire sales fee
paid by such purchaser.

     Beginning nine business days prior to, but no later than, the scheduled
termination date described in the prospectus, the trustee may begin to sell all
of the remaining underlying securities on behalf of unitholders in connection
with the termination of the trust.  The sponsor may assist the trustee in these
sales and receive compensation to the extent permitted by applicable law.  The
sale proceeds will be net of any incidental expenses involved in the sales.

     The sponsor will generally instruct the trustee to sell the securities as
quickly as practicable during the termination proceedings without in its
judgment materially adversely affecting the market price of the securities, but
it is expected that all of the securities will in any event be disposed of
within a reasonable time after a trust's termination.  The sponsor does not
anticipate that the period will be longer than one month, and it could be as
short as one day, depending on the liquidity of the securities being sold.  The
liquidity of any security depends on the daily trading volume of the security
and the amount that the sponsor has available for sale on any particular day.
Of course, no assurances can be given that the market value of the securities
will not be adversely affected during the termination proceedings.

     Approximately thirty days prior to termination of a trust, the trustee will
notify unitholders of the termination and provide a form allowing qualifying
unitholders to elect an in-kind distribution.  A unitholder who owns the minimum
number of units described in the prospectus may request an in-kind distribution
from the trustee instead of cash.  The trustee will make an in-kind distribution
through the distribution of each of the securities of the trust in book entry
form to the account of the unitholder's bank or broker-dealer at Depository
Trust Company.  The unitholder will be entitled to receive whole shares of each
of the securities comprising the


                                      -11-


portfolio of a trust and cash from the Capital Account equal to the fractional
shares to which the unitholder is entitled.  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 sponsor may terminate the in-
kind distribution option at any time upon notice to the unitholders.  Special
federal income tax consequences will result if a unitholder requests an in-kind
distribution.

     Within a reasonable period after termination, the trustee will sell any
securities remaining in a trust and, after paying all expenses and charges
incurred by the trust, will distribute to unitholders thereof their pro rata
share of the balances remaining in the Income and Capital Accounts of the trust.

     The sponsor may, but is not obligated to, offer for sale units of a
subsequent series of a trust at approximately the time of the mandatory
termination date.  If the sponsor does offer such units for sale, unitholders
may be given the opportunity to purchase such units at a public offering price
that includes a reduced sales fee.  There is, however, no assurance that units
of any new series of a trust will be offered for sale at that time, or if
offered, that there will be sufficient units available for sale to meet the
requests of any or all unitholders.

     THE TRUSTEE.  The trustee is The Bank of New York Mellon, a trust company
organized under the laws of New York.  The Bank of New York Mellon has its
principal unit investment trust division offices at 2 Hanson Place, 12th Floor,
Brooklyn, New York 11217, (800) 848-6468.  The Bank of New York Mellon 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 trustee, whose duties are ministerial in nature, has not participated
in selecting the portfolio of any trust.  In accordance with the trust
agreement, the trustee shall keep records of all transactions at its office.
Such records shall include the name and address of, and the number of units held
by, every unitholder of a trust.  Such books and records shall be open to
inspection by any unitholder at all reasonable times during usual business
hours.  The trustee shall make such annual or other reports as may from time to
time be required under any applicable state or federal statute, rule or
regulation.  The trustee shall keep a certified copy or duplicate original of
the trust agreement on file in its office available for inspection at all
reasonable times during usual business hours by any unitholder, together with a
current list of the securities held in each trust.  Pursuant to the trust
agreement, the trustee may employ one or more agents for the purpose of custody
and safeguarding of securities comprising a trust.

     Under the trust agreement, the trustee or any successor trustee may resign
and be discharged of a trust created by the trust agreement by executing an
instrument in writing and filing the same with the sponsor.

     The trustee or successor trustee must mail a copy of the notice of
resignation to all unitholders then of record, not less than sixty 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


                                      -12-


has been appointed and has accepted the appointment within thirty days after
notification, the retiring trustee may apply to a court of competent
jurisdiction for the appointment of a successor.  In case at any time the
trustee shall not meet the requirements set forth in the trust agreement, or
shall become incapable of acting, or if a court having jurisdiction in the
premises shall enter a decree or order for relief in respect of the trustee in
an involuntary case, or the trustee shall commence a voluntary case, under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or any receiver, liquidator, assignee, custodian, trustee, sequestrator
(or similar official) for the trustee or for any substantial part of its
property shall be appointed, or the trustee shall generally fail to pay its
debts as they become due, or shall fail to meet such written standards for the
trustee's performance as shall be established from time to time by the sponsor,
or if the sponsor determines in good faith that there has occurred either (1) a
material deterioration in the creditworthiness of the trustee or (2) one or more
grossly negligent acts on the part of the trustee with respect to a trust, the
sponsor, upon sixty days' prior written notice, may remove the trustee and
appoint a successor trustee, as hereinafter provided, by written instrument, in
duplicate, one copy of which shall be delivered to the trustee so removed and
one copy to the successor trustee.  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 trustee must be a corporation organized under the laws of the
United States, or any state thereof, be authorized under such laws to exercise
trust powers and have at all times an aggregate capital, surplus and undivided
profits of not less than $5,000,000.

     THE SPONSOR.  The sponsor of the trust is Advisors Asset Management, Inc.
acting through its unit investment trust division.  The sponsor is a broker-
dealer specializing in providing services to broker-dealers, registered
representatives, investment advisers and other financial professionals.  The
sponsor's headquarters are located at 18925 Base Camp Road, Monument, Colorado
80132.  You can contact the unit investment trust division at 8100 East 22nd
Street North, Building 800, Suite 102, Wichita, Kansas 67226 or by using the
contacts listed on the back cover of the prospectus.  The sponsor is a
registered broker-dealer and investment adviser and a member of the Financial
Industry Regulatory Authority, Inc. (FINRA) and the Securities Investor
Protection Corporation (SIPC), and a registrant of the Municipal Securities
Rulemaking Board (MSRB).

     If at any time the sponsor shall fail to perform any of its duties under
the trust agreement or shall become incapable of acting or shall be adjudged a
bankrupt or insolvent or shall have its affairs taken over by public
authorities, then the trustee may (a) appoint a successor sponsor at rates of
compensation deemed by the trustee to be reasonable and not exceeding such
reasonable amounts as may be prescribed by the Securities and Exchange
Commission, (b) terminate the trust agreement and liquidate any trust as
provided therein, or (c) continue to act as trustee without terminating the
trust agreement.

     THE EVALUATOR AND SUPERVISOR.  Advisors Asset Management, Inc., the
sponsor, also serves as evaluator and supervisor.  The evaluator and supervisor
may resign or be removed by the sponsor and trustee in which event the sponsor
or trustee is to use its best efforts to appoint a satisfactory successor.  Such
resignation or removal shall become effective upon acceptance of appointment by
the successor evaluator.  If upon resignation of the evaluator no successor has


                                      -13-


accepted appointment within thirty days after notice of resignation, the
evaluator may apply to a court of competent jurisdiction for the appointment of
a successor.  Notice of such resignation or removal and appointment shall be
mailed by the trustee to each unitholder.

     LIMITATIONS ON LIABILITY.  The sponsor, evaluator, and supervisor are
liable for the performance of their obligations arising from their
responsibilities under the trust agreement but will be under no liability to the
unitholders for taking any action or refraining from any action in good faith
pursuant to the trust agreement or for errors in judgment, except in cases of
its own gross negligence, bad faith or willful misconduct or its reckless
disregard for its duties thereunder.  The sponsor shall not be liable or
responsible in any way for depreciation or loss incurred by reason of the sale
of any securities.

     The trust agreement provides that the trustee shall be under no liability
for any action taken in good faith in reliance upon prima facie properly
executed documents or for the disposition of moneys, securities or certificates
except by reason of its own gross negligence, bad faith or willful misconduct,
or its reckless disregard for its duties under the trust agreement, nor shall
the trustee be liable or responsible in any way for depreciation or loss
incurred by reason of the sale by the trustee of any securities.  In the event
that the sponsor shall fail to act, the trustee may act and shall not be liable
for any such action taken by it in good faith.  The trustee shall not be
personally liable for any taxes or other governmental charges imposed upon or in
respect of the securities or upon the interest thereof.  In addition, the trust
agreement contains other customary provisions limiting the liability of the
trustee.

     The trustee and unitholders may rely on any evaluation furnished by the
evaluator and shall have no responsibility for the accuracy thereof.  The trust
agreement provides that the determinations made by the evaluator shall be made
in good faith upon the basis of the best information available to it, provided,
however, that the evaluator shall be under no liability to the trustee or
unitholders for errors in judgment, but shall be liable for its gross
negligence, bad faith or willful misconduct or its reckless disregard for its
obligations under the trust agreement.

     EXPENSES OF THE TRUST.  The sponsor will not charge a trust any fees for
services performed as sponsor.  The sponsor will receive a portion of the sale
commissions paid in connection with the purchase of units and will share in
profits, if any, related to the deposit of securities in the trust.

     The sponsor may receive a fee from your trust for creating and developing
the trust, including determining the trust's objectives, policies, composition
and size, selecting service providers and information services and for providing
other similar administrative and ministerial functions.  The amount of this
"creation and development fee" is set forth in the prospectus.  The trustee will
deduct this amount from your trust's assets as of the close of the initial
offering period.  No portion of this fee is applied to the payment of
distribution expenses or as compensation for sales efforts.  This fee will not
be deducted from proceeds received upon a repurchase, redemption or exchange of
units before the close of the initial public offering period.

     The trustee receives for its services that fee set forth in the prospectus.
The trustee's fee which is calculated and paid monthly is based on the total
number of units of the related trust


                                      -14-


outstanding as of January 1 for any annual period, except during the initial
offering period the fee will be based on the units outstanding at the end of
each month.  The trustee benefits to the extent there are funds for future
distributions, payment of expenses and redemptions in the Capital and Income
Accounts since these Accounts are non-interest bearing and the amounts earned by
the trustee are retained by the trustee.  Part of the trustee's compensation for
its services to a trust is expected to result from the use of these funds.

     The supervisor will charge a trust a surveillance fee for services
performed for the trust in an amount not to exceed that amount set forth in the
prospectus but in no event will such compensation, when combined with all
compensation received from other unit investment trusts for which the sponsor
both acts as sponsor and provides portfolio surveillance, exceed the aggregate
cost to the sponsor of providing such services.  Such fee shall be based on the
total number of units of the related trust outstanding as of January 1 for any
annual period, except during the initial offering period the fee will be based
on the units outstanding at the end of each month.

     For evaluation of the securities in a trust, the evaluator shall receive an
evaluation fee in an amount not to exceed that amount set forth in the
prospectus but in no event will such compensation, when combined with all
compensation from other unit investment trusts for which the sponsor acts as
sponsor and provides evaluation services, exceed the aggregate cost of providing
such services.  Such fee shall be based on the total number of units of the
related trust outstanding as of January 1 for any annual period, except during
the initial offering period the fee will be based on the units outstanding at
the end of each month.

     For providing bookkeeping and administrative services to a trust, the
sponsor shall receive an administration fee in an amount not to exceed that
amount set forth in the prospectus but in no event will such compensation, when
combined with all compensation from other unit investment trusts for which the
sponsor acts as sponsor and provides evaluation services, exceed the aggregate
cost of providing such services.  Such fee shall be based on the total number of
units of the related trust outstanding as of January 1 for any annual period,
except during the initial offering period the fee will be based on the units
outstanding at the end of each month.

     The trustee's fee, sponsor's fee for providing bookkeeping and
administrative services to the trust, supervisor's fee and evaluator's fee are
deducted from the Income Account of the related trust to the extent funds are
available and then from the Capital Account.  Each such fee (other than any
creation and development fee) may be increased without approval of unitholders
by amounts not exceeding a proportionate increase in the Consumer Price Index or
any equivalent index substituted therefor.

     The following additional charges are or may be incurred by the trust:
(a) fees for the trustee's extraordinary services; (b) expenses of the trustee
(including legal and auditing expenses and reimbursement of the cost of advances
to the trust for payment of expenses and distributions, but not including any
fees and expenses charged by an agent for custody and safeguarding of
securities) and of counsel, if any; (c) various governmental charges;
(d) expenses and costs of any action taken by the trustee to protect the trust
or the rights and interests of the unitholders; (e) indemnification of the
trustee for any loss, liability or expense incurred by it in


                                      -15-


the administration of the trust not resulting from negligence, bad faith or
willful misconduct on its part or its reckless disregard of its obligations
under the trust agreement; (f) indemnification of the sponsor for any loss,
liability or expense incurred in acting in that capacity without gross
negligence, bad faith or willful misconduct or its reckless disregard for its
obligations under the trust agreement; and (g) expenditures incurred in
contacting unitholders upon termination of the trust.  The fees and expenses set
forth herein are payable out of a trust and, when owing to the trustee, are
secured by a lien on the trust.  If the balances in the Income and Capital
Accounts are insufficient to provide for amounts payable by the trust, the
trustee has the power to sell securities to pay such amounts.  These sales may
result in capital gains or losses to unitholders.  A trust may pay the costs of
updating its registration statement each year.

PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION

     When a 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 sponsor to specify minimum amounts 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 trust, the sponsor or dealers participating in the offering
of units.

PURCHASE, REDEMPTION AND PRICING OF UNITS

     PUBLIC OFFERING PRICE.  Units of a trust are offered at the public offering
price thereof.  The public offering price per unit is equal to the net asset
value per unit plus organization costs plus the applicable sales fee referred to
in the prospectus.  The initial sales fee is equal to the difference between the
maximum sales fee and the sum of the remaining deferred sales fee and the total
creation and development fee.  The sales fee as a percentage of the public
offering price and the net amount invested is set forth in the prospectus.  The
deferred sales fee is a fixed dollar amount and will be collected in
installments as described in the prospectus.  The creation and development fee
is a fixed dollar amount and will be collected at the end of the initial
offering period as described in the prospectus.  Units purchased after the
initial deferred sales fee payment will be subject to the remaining deferred
sales fee payments.  Units sold or redeemed prior to such time as the entire
applicable deferred sales fee has been collected will be assessed the remaining
deferred sales fee at the time of such sale or redemption.  Units sold or
redeemed prior to such time as the entire applicable creation and development
fee has been collected will not be assessed the remaining creation and
development fee at the time of such sale or redemption.  During the initial
offering period, 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 a
trust.  These costs include the cost of preparing the registration statement,
the trust indenture and other closing documents, registering units with the
Securities and Exchange Commission and states, the initial audit of the trust
portfolio, legal fees and the initial fees and expenses of the trustee.  These
costs will be deducted from a trust as of the end of the initial offering period
or after six months, if earlier.  Certain broker-dealers may charge a
transaction fee for processing unit purchases.


                                      -16-


     As indicated above, the initial public offering price of the units was
established by dividing the aggregate underlying value of the securities by the
number of units outstanding.  Such price determination as of the opening of
business on the date a trust was created was made on the basis of an evaluation
of the securities in the trust prepared by the evaluator.  After the opening of
business on this date, the evaluator will appraise or cause to be appraised
daily the value of the underlying securities as of the close of regular trading
on the New York Stock Exchange on days the New York Stock Exchange is open and
will adjust the public offering price of the units commensurate with such
valuation.  Such public offering price will be effective for all orders received
at or prior to the close of regular trading on the New York Stock Exchange on
each such day as discussed in the prospectus.  Orders received by the trustee,
sponsor or authorized financial professionals for purchases, sales or
redemptions after that time, or on a day when the New York Stock Exchange is
closed, will be held until the next determination of price as discussed in the
prospectus.

     Had units of a trust been available for sale at the close of business on
the business day before the inception date of the trust, the public offering
price would have been as shown under "Essential Information" in the prospectus.
The public offering price per unit of a trust on the date of the prospectus or
on any subsequent date will vary from the amount stated under "Essential
Information" in the prospectus in accordance with fluctuations in the prices of
the underlying securities.  Net asset value per unit is determined by dividing
the value of a trust's portfolio securities, cash and other assets, less all
liabilities, by the total number of units outstanding.  The portfolio securities
are valued by the evaluator as follows: If the security is listed on a national
securities exchange, the evaluation will generally be based on the last sale
price on the exchange (unless the evaluator deems the price inappropriate as a
basis for evaluation).  If the security is not so listed or, if so listed and
the principal market for the security is other than on the exchange, the
evaluation will generally be made by the evaluator in good faith based on an
appraisal of the fair value of the securities using recognized pricing methods.

     The foregoing evaluations and computations shall be made as of the close of
regular trading on the New York Stock Exchange, on each business day commencing
with the trust's inception date of the securities, effective for all sales made
during the preceding 24-hour period.

     Although payment is normally made three business days following the order
for purchase, payments may be made prior thereto.  A person will become the
owner of units on the date of settlement provided payment has been received.
Cash, if any, made available to the sponsor prior to the date of settlement for
the purchase of units may be used in the sponsor's business and may be deemed to
be a benefit to the sponsor, subject to the limitations of the Securities
Exchange Act of 1934.

     PUBLIC DISTRIBUTION OF UNITS.  The sponsor intends to qualify the units for
sale in a number of states.  Units will be sold through dealers who are members
of the National Association of Securities Dealers, Inc.  and through others.
Sales may be made to or through dealers at prices which represent discounts from
the public offering price as set forth in the prospectus.  Certain commercial
banks may be making units available to their customers on an agency basis.  The
sponsor reserves the right to change the discounts from time to time.


                                      -17-


     We may provide, at our own expense and out of our own profits, additional
compensation and benefits to broker-dealers who sell shares of units of this
trust and our other products.  This compensation is intended to result in
additional sales of our products and/or compensate broker-dealers and financial
advisors for past sales.  We may make these payments for marketing, promotional
or related expenses, including, but not limited to, expenses of entertaining
retail customers and financial advisors, advertising, sponsorship of events or
seminars, obtaining shelf space in broker-dealer firms and similar activities
designed to promote the sale of the our products.  These arrangements will not
change the price you pay for your units.

     The sponsor reserves the right to reject, in whole or in part, any order
for the purchase of units.

     PROFITS OF SPONSOR.  The sponsor will receive gross sales fees equal to the
percentage of the offering price of the units of such trusts stated in the
prospectus and will pay a portion of such sales fees to dealers and agents.  In
addition, the sponsor may realize a profit or a loss resulting from the
difference between the purchase prices of the securities to the sponsor and the
cost of such securities to a trust.  The sponsor may also realize profits or
losses with respect to securities deposited in a trust which were acquired from
underwriting syndicates of which the sponsor was a member.  An underwriter or
underwriting syndicate purchases securities from the issuer on a negotiated or
competitive bid basis, as principal, with the motive of marketing such
securities to investors at a profit.  The sponsor may realize additional profits
or losses during the initial offering period on unsold units as a result of
changes in the daily evaluation of the securities in a trust.

     MARKET FOR UNITS.  After the initial offering period, while not obligated
to do so, the sponsor may, subject to change at any time, maintain a market for
units of the trust offered hereby and to continuously offer to purchase said
units at the net asset value determined by the evaluator, provided that the
repurchase price will not be reduced by any remaining creation and development
fee or organization costs during the initial offering period.  While the sponsor
may repurchase units from time to time, it does not currently intend to maintain
an active secondary market for units.  Unitholders who wish to dispose of their
units should inquire of their broker as to current market prices in order to
determine whether there is in existence any price in excess of the redemption
price and, if so, the amount thereof.  Unitholders who sell or redeem units
prior to such time as the entire deferred sales fee on such units has been
collected will be assessed the amount of the remaining deferred sales fee at the
time of such sale or redemption.  Unitholders who sell or redeem units prior to
such time as the entire creation and development fee on such units has been
collected will not be assessed the amount of the remaining creation and
development fee at the time of such sale or redemption.  The offering price of
any units resold by the sponsor will be in accord with that described in the
currently effective prospectus describing such units.  Any profit or loss
resulting from the resale of such units will belong to the sponsor.  If the
sponsor decides to maintain a secondary market, it may suspend or discontinue
purchases of units of the trust if the supply of units exceeds demand, or for
other business reasons.

     REDEMPTION.  A unitholder who does not dispose of units in the secondary
market described above may cause units to be redeemed by the trustee by making a
written request to the trustee at its unit investment trust division office.
Unitholders must sign the request exactly as


                                      -18-


their names appear on the records of the trustee.  Additional documentation may
be requested, and a signature guarantee is always required, from corporations,
executors, administrators, trustees, guardians or associations.  The signatures
must be guaranteed by a participant in the Securities Transfer Agents Medallion
Program ("STAMP") or such other signature guaranty program in addition to, or in
substitution for, STAMP, as may be accepted by the trustee.

     Redemption shall be made by the trustee no later than the seventh day
following the day on which a tender for redemption is received (the "Redemption
Date") by payment of cash equivalent to the redemption price, determined as set
forth below under "Computation of Redemption Price," as of the close of regular
trading on the New York Stock Exchange next following such tender, multiplied by
the number of units being redeemed.  Any units redeemed shall be canceled and
any undivided fractional interest in the related trust extinguished.  The price
received upon redemption might be more or less than the amount paid by the
unitholder depending on the value of the securities in the trust at the time of
redemption.  Unitholders who sell or redeem units prior to such time as the
entire deferred sales fee on such units has been collected will be assessed the
amount of the remaining deferred sales fee at the time of such sale or
redemption.  Unitholders who sell or redeem units prior to such time as the
entire creation and development fee on such units has been collected will not be
assessed the amount of the remaining creation and development fee at the time of
such sale or redemption.  Certain broker-dealers may charge a transaction fee
for processing redemption requests.

     Under regulations issued by the Internal Revenue Service, the trustee is
required to withhold a specified percentage of the principal amount of a unit
redemption if the trustee has not been furnished the redeeming unitholder's tax
identification number in the manner required by such regulations.  Any amount so
withheld is transmitted to the Internal Revenue Service and may be recovered by
the unitholder only when filing a tax return.  Under normal circumstances, the
trustee obtains the unitholder's tax identification number from the selling
broker.  However, any time a unitholder elects to tender units for redemption,
such unitholder should make sure that the trustee has been provided a certified
tax identification number in order to avoid this possible "back-up withholding."
In the event the trustee has not been previously provided such number, one must
be provided at the time redemption is requested.  Any amounts paid on redemption
representing interest shall be withdrawn from the Income Account of a trust to
the extent that funds are available for such purpose.  All other amounts paid on
redemption shall be withdrawn from the Capital Account for a trust.

     Unitholders tendering units for redemption may request a distribution in
kind (a "Distribution In Kind") from the trustee in lieu of cash redemption of
an amount and value of securities per unit equal to the redemption price per
unit as determined as of the evaluation time next following the tender, provided
that the tendering unitholder meets the requirements stated in the prospectus
and the unitholder has elected to redeem at least thirty days prior to the
termination of the trust.  If the unitholder meets these requirements, a
Distribution In Kind will be made by the trustee through the distribution of
each of the securities of the trust in book entry form to the account of the
unitholder's bank or broker-dealer at Depository Trust Company.  The tendering
unitholder shall be entitled to receive whole shares of each of the securities
comprising the portfolio of the trust and cash from the Capital Account equal to
the fractional shares to which the tendering unitholder is entitled.  The
trustee shall make any adjustments necessary to


                                      -19-


reflect differences between the redemption price of the units and the value of
the securities distributed in kind as of the date of tender.  If funds in the
Capital Account are insufficient to cover the required cash distribution to the
tendering unitholder, the trustee may sell securities.  The in kind redemption
option may be terminated by the sponsor at any time.

     The trustee is empowered to sell securities in order to make funds
available for the redemption of units.  To the extent that securities are sold
or redeemed in-kind, the size of a trust will be, and the diversity of a trust
may be, reduced but each remaining unit will continue to represent approximately
the same proportional interest in each security.  Sales may be required at a
time when securities would not otherwise be sold and may result in lower prices
than might otherwise be realized.  The price received upon redemption may be
more or less than the amount paid by the unitholder depending on the value of
the securities in the portfolio at the time of redemption.

     The trustee is irrevocably authorized in its discretion, if the sponsor
does not elect to purchase any unit tendered for redemption, in lieu of
redeeming such units, to sell such units in the over-the-counter market for the
account of tendering unitholders at prices which will return to the unitholders
amounts in cash, net after brokerage commissions, transfer taxes and other
charges, equal to or in excess of the redemption price for such units.  In the
event of any such sale, the trustee shall pay the net proceeds thereof to the
unitholders on the day they would otherwise be entitled to receive payment of
the redemption price.

     The right of redemption may be suspended and payment postponed (1) for any
period during which the New York Stock Exchange is closed, other than customary
weekend and holiday closings, or during which (as determined by the Securities
and Exchange Commission) trading on the New York Stock Exchange is restricted;
(2) for any period during which an emergency exists as a result of which
disposal by the trustee of securities is not reasonably practicable or it is not
reasonably practicable to fairly determine the value of the underlying
securities in accordance with the trust agreement; or (3) for such other period
as the Securities and Exchange Commission may by order permit.  The trustee is
not liable to any person in any way for any loss or damage which may result from
any such suspension or postponement.

     COMPUTATION OF REDEMPTION PRICE.  The redemption price for units of each
trust is computed by the evaluator as of the evaluation time stated in the
prospectus next occurring after the tendering of a unit for redemption and on
any other business day desired by it, by:

A.   Adding: (1) the cash on hand in the trust other than cash deposited in the
     trust to purchase securities not applied to the purchase of such securities
     and (2) the aggregate value of each issue of the securities held in the
     trust as determined by the evaluator as described above;

B.   Deducting therefrom (1) amounts representing any applicable taxes or
     governmental charges payable out of the trust and for which no deductions
     have been previously made for the purpose of additions to the Reserve
     Account; (2) an amount representing estimated accrued expenses, including
     but not limited to fees and expenses of the trustee (including legal and
     auditing fees), the evaluator, the sponsor and counsel, if any; (3) cash


                                      -20-


     held for distribution to unitholders of record as of the business day prior
     to the evaluation being made; and (4) other liabilities incurred by the
     trust, provided that the redemption price will not be reduced by any
     remaining creation and development fee or organization costs during the
     initial offering period; and

C.   Finally dividing the results of such computation by the number of units of
     the trust outstanding as of the date thereof.

     RETIREMENT PLANS.  A trust may be suited for purchase by Individual
Retirement Accounts, Keogh Plans, pension funds and other qualified retirement
plans.  Generally, capital gains and income received under each of the foregoing
plans are deferred from Federal taxation.  All distributions from such plans are
generally treated as ordinary income but may, in some cases, be eligible for
special income averaging or tax-deferred rollover treatment.  Investors
considering participation in any such plan should review specific tax laws
related thereto and should consult their attorneys or tax advisers with respect
to the establishment and maintenance of any such plan.  Such plans are offered
by brokerage firms and other financial institutions.  The trust will lower the
minimum investment requirement for IRA accounts.  Fees and charges with respect
to such plans may vary.

     OWNERSHIP OF UNITS.  Ownership of units will not be evidenced by
certificates.  Units may be purchased in denominations of one unit or any
multiple thereof, subject to the minimum investment requirement.  Fractions of
units, if any, will be computed to three decimal places.

PERFORMANCE INFORMATION

     Information contained in this Information Supplement or in the prospectus,
as it currently exists or as further updated, may also be included from time to
time in other prospectuses or in advertising material.  Information on the
performance of a trust strategy or the actual performance of a trust may be
included from time to time in other prospectuses or advertising material and may
reflect sales fees and expenses of a trust.  The performance of a trust may also
be compared to the performance of money managers as reported in SEI Fund
Evaluation Survey or of mutual funds as reported by Lipper Analytical Services
Inc.  (which calculates total return using actual dividends on ex-dates
accumulated for the quarter and reinvested at quarter end), Money Magazine Fund
Watch (which rates fund performance over a specified time period after sales fee
and assuming all dividends reinvested) or Wiesenberger Investment Companies
Service (which states fund performance annually on a total return basis) or of
the New York Stock Exchange Composite Index, the American Stock Exchange Index
(unmanaged indices of stocks traded on the New York and American Stock
Exchanges, respectively), the Dow Jones Industrial Average (an index of 30
widely traded industrial common stocks) or the Standard & Poor's 500 Index (an
unmanaged diversified index of 500 stocks) or similar measurement standards
during the same period of time.
