INVESTMENT SUMMARY

     USE THIS INVESTMENT SUMMARY TO HELP YOU DECIDE WHETHER AN INVESTMENT IN
THIS TRUST IS RIGHT FOR YOU. MORE DETAILED INFORMATION CAN BE FOUND LATER IN
THIS PROSPECTUS.

                                    OVERVIEW

     Claymore Securities Defined Portfolios, Series 201 is a unit investment
trust that consists of the Peroni Top Ten Picks Portfolio, 2005 Series (the
"TRUST"). The trust seeks to provide capital appreciation by investing in common
stocks of companies selected by Eugene E. Peroni, Jr. through the application of
the Peroni Method. Claymore Securities, Inc. ("CLAYMORE" or the "SPONSOR")
serves as the sponsor of the trust.

     The trust is scheduled to terminate in approximately 15 months.

                              INVESTMENT OBJECTIVE

     The trust seeks to provide capital appreciation.

                          PRINCIPAL INVESTMENT STRATEGY

     The trust consists of ten common stocks included in the list of Top Ten
Picks selected and published by Eugene E. Peroni, Jr. for 2005. Mr. Peroni
applies the Peroni Method to select the stocks for the Top Ten Picks list. The
Top Ten Picks are the ten stocks that Mr. Peroni believes have the strongest
potential for capital appreciation over the next 15 months. The Top Ten Picks
list for 2005 is published by Mr. Peroni and Claymore, the sponsor and portfolio
supervisor of the portfolio. Mr. Peroni has selected and published the Top Ten
Picks list each year since 1988.

     The Peroni Method is an intensive, bottom-up methodology, tracking over
1,000 stocks on a daily basis. It is heavily, but not exclusively, based on
proprietary technical analysis. Generally, investors focus on attractive
fundamental factors such as price-earnings ratios, dividend growth and cash
flows when selecting stocks for their portfolios. However, technical factors,
including how a stock behaves relative to general market trends, also can play
an important role in investment success. Identifying a stock's accumulation
characteristics can aid in increasing portfolio returns, but it is only one of
many factors used to choose a portfolio.

     In an inherently volatile stock market environment, the best strategy may
be a disciplined approach. Investors who hold a balanced portfolio of quality
investments and maintain a long-term posture may have a much better chance of
achieving their financial goals. The trust uses a buy-and-hold approach to help
achieve its investment objective and accordingly, the stocks included are
expected to remain in the trust until termination. The trust's buy-and-hold
philosophy relies on patience and discipline and eliminates the temptation to
respond hastily to market factors outside of your control.

     See "Investment Policies" in Part B of the prospectus for more information.

                               SECURITY SELECTION

     Mr. Peroni utilizes the Peroni Method of technical analysis to select the
trust's portfolio. The Peroni Method is based on primarily proprietary technical
analysis. While fundamental factors such as the price/earnings ratio and free
cash flow can be important considerations, technical factors such as price
patterns and accumulation trends can play an important role in investment
decisions as well. Gene Peroni

                                        2
<Page>

believes, the manner in which a stock has behaved historically can provide
insights as to its future growth prospects. The Peroni Method of technical
analysis examines numerous technical, psychological and fundamental data. They
include:

     -    a stock's historical price architecture

     -    net money flow trends in individual stocks

     -    the relative behavior of a stock's price performance compared to other
          stocks in the same industry

     -    sentiment readings such as the volatility index and the put/call ratio

     -    fiscal and monetary factors

     -    geopolitical events and their impact on specific industry groups


     Gene Peroni selects the stocks that he believes are best suited to the
trust's investment objective of capital appreciation over a defined time period.

     According to Mr. Peroni, "[t]he Peroni Method has been used to analyze
individual stock patterns and general market trends over five decades. Its
reliance on both proprietary and broadly disseminated technical data has proven
highly effective, especially during times of tumultuous market conditions. The
current environment of corporate misdeeds and Wall Street research scrutiny have
brought technical research to the foreground as a less biased means of
deciphering a stock's practical underlying potential in the marketplace."

                                  FUTURE TRUSTS

     The sponsor intends to create future trusts that follow the same investment
strategy. One such trust is expected to be available approximately one year
after the trust's inception date (the "INCEPTION DATE"). If these future trusts
are available, you may be able to reinvest into one of the trusts at a reduced
sales charge. Each trust is designed to be part of a longer term strategy.

                                 PRINCIPAL RISKS

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

     -    STOCK PRICES CAN BE VOLATILE. The value of your investment may fall
          over time. Market value fluctuates in response to various factors.
          These can include stock market movements, purchases or sales of
          securities by the trust, government policies, litigation, and changes
          in interest rates, inflation, the financial condition of the
          securities' issuer or even perceptions of the issuer.

     -    THE SPONSOR DOES NOT ACTIVELY MANAGE THE PORTFOLIO. The trust will
          generally hold, and may continue to buy, the same

                                        3
<Page>

          stocks even though the stock's outlook or its market value or yield
          may have changed.

     -    Share prices or dividend rates on the stocks may decline during the
          life of the trust.

     -    THE PERONI METHOD MAY NOT IDENTIFY STOCKS THAT WILL SATISFY THE
          TRUST'S INVESTMENT OBJECTIVE.

     -    The trust is considered to be concentrated in securities issued by
          companies in the               industry. A concentration makes the
          trust subject to more risk. Companies involved in this industry must
          contend with

     See "Risk Factors" in Part B of the Prospectus and "Investment Risks" in
Part A of the Prospectus for additional information.

                                WHO SHOULD INVEST

     You should consider this investment if:

     -    You want to own a defined portfolio of stocks selected through the
          Peroni Method.

     -    You seek capital appreciation.

     -    The trust represents only a portion of your overall investment
          portfolio.

     -    The trust is part of a longer-term investment strategy that includes
          the investment in subsequent portfolios, if available.

     -    The trust is combined with other investment vehicles to provide
          diversification of method to your overall portfolio.

     You should not consider this investment if:

     -    You are uncomfortable with the trust's strategy.

     -    You are uncomfortable with the risks of an unmanaged investment in
          stocks.

     -    You want current income or capital preservation.

</Table>

(1)  The initial sales fee provided above is based on the unit price on the
     trust's inception date (the "INCEPTION DATE"). Because the initial sales
     fee equals the difference between the maximum sales fee and the sum of the
     remaining deferred sales fee and the creation and development fee ("C&D
     FEE") (as described below), the percentage and dollar amount of the initial
     sales fee will vary as the unit price varies and after deferred charges
     begin. Despite the variability of the initial sales fee, each investor is
     obligated to pay the entire applicable maximum sales fee.

(2)  The deferred sales fee is fixed at $0.145 per unit and is deducted in
     monthly installments of $0.048 per unit on the last business day of each
     month in April, 2005 and May, 2005 and $0.049 in June, 2005. The percentage
     provided is based on a $10 unit as of the Inception Date and the percentage
     amount will vary over time.

(3)  The C&D Fee compensates the sponsor for creating and developing your trust.
     The actual C&D Fee is $0.050 per unit and is paid to the sponsor at the
     close of the initial offering period, which is expected to be

                                        5
<Page>

     approximately three months from the Inception Date. The percentages
     provided are based on a $10 unit as of the Inception Date and the
     percentage amount will vary over time. If the unit price exceeds $10.00 per
     unit, the C&D Fee will be less than 0.50% of the Public Offering Price; if
     the unit price is less than $10.00 per unit, the C&D Fee will exceed 0.50%
     of the Public Offering Price.

(4)  Based on 100 units with a $10 per unit Public Offering Price as of the
     Inception Date.

(5)  Other operating expenses do not include brokerage cost and other
     transactional fees.

                                     EXAMPLE

     This example helps you compare the costs of this trust with other unit
trusts and mutual funds. In the example we assume that you reinvest your
investment in a new trust each year, the expenses do not change and 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:

<Table>
                                                     
     1 year                                             $
     3 years
     5 years
     Life
</Table>

     These amounts are the same regardless of whether you sell your investment
at the end of a period or continue to hold your investment. The example does not
consider any brokerage fees paid by the trust or transaction fees that
broker-dealers may charge for processing redemption requests.

     See "Expenses of the Trust" in Part B of the prospectus for additional
information.

                      ESTIMATED ANNUAL INCOME DISTRIBUTIONS

     The portfolio's estimated annual income distributions are $ per unit for
the first year. The amount of distributions may increase or decrease as
securities in the portfolio mature, are called or are sold, as the dividends
received change or as fees and expenses increase or decrease. Estimated
distributions assume that all of the securities and expected dividends are
delivered to the portfolio. These figures are estimated as of the business day
prior to the Inception Date; actual payments may vary.

     See "Expenses of the Trust" in Part B of the prospectus for additional
information.

                         COMPARATIVE PRICE APPRECIATION

     The trust consists of the stocks included and published in Mr. Peroni's Top
Ten Picks list for 2005. The sponsor intends to create each year future trusts
that consist of the stocks included in Mr. Peroni's Top Ten Picks list for a
given year. A new trust is expected to be available for purchase approximately
one year after the Inception Date. To illustrate the historical hypothetical
price appreciation figures of the Top Ten Picks lists, a model investment trust
has been assembled. To create the model trust we assumed that a hypothetical
investor made an initial $10,000 investment in the securities selected for the
Peroni Top Ten Picks list for 1989. Each following year the model assumed that
the hypothetical investor sells the former Peroni Top Ten Picks and purchases
the Peroni Top Ten Picks for the next year with the sale proceeds. The following
table compares the yearly hypothetical price appreciation figures of the Top Ten
Picks lists (but not any actual trust) with the actual price appreciation
figures of the stocks in the Dow Jones Industrial Average ("DJIA") and the
stocks in the Standard & Poor's 500 Index ("S&P 500") from December 19, 1988 to
December 8, 2003.

     The price appreciation figures of the Top Ten Picks lists show the
performance of the stocks included for each period. These price appreciation
figures are not those of the trust. The performance figures for the Peroni Top
10 Picks lists do include the sales charges and estimated expenses of the trust.
The performance provided is no assurance of future results of either the Top Ten
Picks list or the trust. Mr. Peroni possesses the right to use the previously
published Peroni Top Ten Picks lists and only Claymore and Mr. Peroni, so long
as Mr. Peroni is employed by Claymore, are able to authorize any party to
utilize the Peroni Top Ten Picks or the hypothetical performance of the Top Ten
Picks in connection with any investment product.

</Table>

(1)  The hypothetical price appreciation figures for "Peroni's Top Ten Picks"
     are net of estimated fees, expenses and sales charges of the trust and do
     not reflect the impact of dividends. Price appreciation represents the sum
     of the change in market value of each group of stocks between the first and
     last trading day of a period. Price appreciation figures assume no dividend
     reinvestment or accumulation. Assumed fees and expenses for year one are as
     follows: upfront sales charge of 1.00%, deferred sales charge of 1.80% and
     fees of 1.00%. The price appreciation figures for year two and beyond
     assume no upfront sales charge and total fees and expenses of 2.80%. It is
     assumed that the securities are purchased in equal dollar amounts on the
     day the stocks are recommended by Mr. Peroni and sold at the closing price
     on the last business date before the subsequent "Peroni's Top Ten Picks"
     are selected. The price appreciation figures for the DJIA and S&P 500
     assume no fees, expenses or sales charges and do not reflect the impact of
     dividends. The Peroni Top Ten Picks Portfolio, 2005 Series list is
     Claymore's third publication of the Top Ten Picks list. Prior Top Ten Picks
     lists were published by Nuveen Investments and Janney Montgomery Scott Inc.
     The price appreciation figures from a trust will differ from the Top Ten
     Picks figures for several reasons including the following:

     -    the trust bears brokerage commissions in buying and selling stocks;

     -    the Top Ten Picks' figures do not reflect any commissions;

     -    Units may be purchased on days after the publication of the Top Ten
          Picks list;

     -    Units are bought and sold based on the closing stock prices on the
          exchange, while the trust may buy and sell stocks at prices during the
          trading day;

     -    the trust may not be fully invested at all times; and

     -    stocks in the trust may not be weighted equally at all times.

(2)  No commissions or taxes were included in the calculations for the Top Ten
     Picks, the DJIA, or the S&P 500. In addition, the price appreciation
     figures provided above do not reflect any dividends paid on the stocks
     included in the Top Ten Picks or the indices. Dividends can be an important
     component of total return. If dividends were included in the above
     comparison, the relative performance results of the Top Ten Picks and the
     indices may have differed. Although the trust seeks to outperform the DJIA
     and the S&P 500, there is no guarantee that it will.

     All contracts for securities are expected to be settled by the initial
     settlement date for the purchase of units.

(2)  Valuation of securities by the evaluator was made using the market value
     per share as of the Evaluation Time on               , 2004. For securities
     quoted on a national or foreign securities exchange or Nasdaq National
     Market System, securities are generally valued at the closing sales price.

(3)  There was a $         loss to the sponsor on the Inception Date.

UNDERSTANDING YOUR INVESTMENT

                                HOW TO BUY UNITS

     You can buy units of the trust on any business day by contacting your
financial professional. The Public Offering Prices of units are available daily
on the Internet at www.claymoresecurities.com. The Public Offering Price
includes:

     -    the value of the stocks,

     -    the initial sales fee, and

     -    cash and other net assets in the portfolio.

     We often refer to the purchase price of units as the "offer price" or the
"PUBLIC OFFERING PRICE." We must receive your order to buy units prior to the
close of the New York Stock Exchange (normally 4:00 p.m. Eastern time) to give
you the price for that day. If we receive your order after this time, you will
receive the price computed on the next business day.

     VALUE OF THE STOCKS. The sponsor serves as the evaluator of the trust (the
"EVALUATOR"). We determine the value of the stocks as of the close of the
New York Stock Exchange on each day that the exchange is open (the "EVALUATION
TIME").

     PRICING THE STOCKS. We generally determine the value of stocks using the
last sale price for stocks traded on a national or foreign securities exchange
or the Nasdaq Stock Market. In some cases we will price a stock 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 stock is not principally
traded on a national or foreign securities exchange or the Nasdaq Stock Market,
or if the market quotes are unavailable or inappropriate.

     The sponsor determined the initial prices of the stocks shown in "Trust
Portfolio" for your trust in this prospectus. The sponsor determined these
initial prices as described above at the close of 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 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 your
purchase price includes a per unit amount sufficient to reimburse us for some or
all of the costs of creating your trust. These costs include the costs of
preparing the registration statement and legal documents, legal fees, federal
and state registration fees and the initial fees and expenses of the trustee.
Your trust will sell stocks to reimburse us for these costs at the end of the
initial offering period or after six months, at the discretion of the sponsor.

     TRANSACTIONAL SALES FEE. You pay a fee when you buy units. We refer to this
fee as the "transactional sales fee." The transaction sales fee has both an
initial and a deferred component and is 2.80% of the Public Offering Price based
on a $10 unit. This percentage amount of the transactional sales fee is based on
the unit price on the Inception Date. Because the transactional sales fee equals
the difference between the maximum sales fee and the C&D Fee, the percentage and
dollar amount of the transactional sales fee will vary as the unit price varies.
The transactional sales fee does not include the C&D Fee which is described
under "Expenses of the Trust" in Part B of the

                                       10
<Page>

Prospectus and in "Fees and Expenses" in Part A of the Prospectus.

     INITIAL SALES FEE. Based on a $10 unit, the initial sales fee is initially
1% of the Public Offering Price. The initial sales fee, which you will pay at
the time of purchase, is equal to the difference between the maximum sales
charge (3.30% of the Public Offering Price) and the sum of the maximum remaining
deferred sales fees and the C&D Fee (initially $0.230 per unit). The dollar
amount and percentage amount of the initial sales fee will vary over time.

     DEFERRED SALES FEE. To keep your money working longer, we defer payment of
the rest of the transactional sales fee through the deferred sales fee ($0.180
per unit).

     REDUCING YOUR SALES FEE. We offer a variety of ways for you to reduce the
maximum sales fee you pay. It is your financial professional's responsibility to
alert us of any discount when you order units. Since the deferred sales fee and
the C&D Fee are a fixed dollar amount per unit, your trust must charge the
deferred sales fee and the C&D Fee per unit regardless of any discounts.
However, if you are eligible to receive a discount such that your total maximum
sales fee is less than the fixed dollar amount of the deferred sales fee and the
C&D Fee, the sponsor will credit you the difference between your maximum sales
fee and the sum of the deferred sales fee and the C&D Fee at the time you buy
units by providing you with additional units.

     LARGE PURCHASES. You can reduce your maximum sales fee by increasing the
size of your investment.

     INVESTORS WHO MAKE LARGE PURCHASES ARE ENTITLED TO THE FOLLOWING SALES
CHARGE REDUCTIONS:

   PURCHASE AMOUNT(1)                 OFFERING PRICE)

   Less than $50,000                          0%
   $50,000 - $99,999                       0.25
   $100,000 - $249,999                     0.50
   $250,000 - $499,999                     0.75
   $500,000 - $999,999                     1.00
   $1,000,000 or more                      1.75
</Table>

(1) Sales charge reductions are computed both on a dollar basis and on the basis
    of the number of units purchased, at any point of purchase, using the
    equivalent of 5,000 units to $50,000, 10,000 units to $100,000 etc., and
    will be applied on that basis which is more favorable to you.

     You may AGGREGATE unit purchases by the same person on any single day from
any one broker-dealer to qualify for a purchase level. You can include these
purchases as your own for purposes of this aggregation:

     -    purchases by your spouse or minor children and

     -    purchases by your trust estate or fiduciary accounts.

     You may also use a LETTER OF INTENT to combine purchases over time to
qualify for a purchase level. Under this option, you must give us a letter of
intent to purchase a specified amount of units of any Claymore unit trust over a
specified time period. The letter must specify a time period of no more than 13
months. Once you sign a letter of intent, we will reduce your fee based on your
total purchase commitment as

                                       11
<Page>

shown in the table above. If your purchases exceed the level specified in your
letter, you will still receive the additional fee reduction for your purchases
shown in the table above (we will not cap your discount). If your total
purchases are less than the level specified in your letter, you must pay the fee
difference to us. We reserve the right to redeem your units if you do not pay
the difference.

     The discounts described above apply only during the initial offering
period.

     There can be no assurance that the sponsor will create future trusts with
investment strategies similar to your trust or that may fit within your
investment parameters. As a result you may not be able to satisfy your letter of
intent.

     ADVISORY AND FEE ACCOUNTS. We eliminate your transactional sales fee for
purchases made through registered investment advisers, certified financial
planners or registered broker-dealers who charge periodic fees in lieu of
commissions or who charge for financial planning or for investment advisory or
asset management services or provide these services as part of an investment
account where a comprehensive "wrap fee" is imposed (a "FEE ACCOUNT").

     This discount applies during the initial offering period and in the
secondary market. Your financial professional may purchase units with the Fee
Account CUSIP number to facilitate purchases under this discount; however, we do
not require that you buy units with this CUSIP number to qualify for the
discount. If you purchase units with this special CUSIP number, you should be
aware that all distributions will automatically reinvest into additional units
of your trust. We reserve the right to limit or deny purchases of units not
subject to the transactional sales charge by investors whose frequent trading
activity we determine to be detrimental to the trust. We, as sponsor, will
receive and you will pay the C&D Fee. See the "Expenses of the Trust" in Part B
of the prospectus.

     EXCHANGE OR ROLLOVER OPTION. If you are buying units of your trust in the
primary market with redemption or termination proceeds from any other Claymore
unit trust, you may purchase units at 99% of the maximum Public Offering Price,
which may include an upfront sales charge and a deferred sales charge. You may
also buy units with this reduced sales fee if you are purchasing units in the
primary market with (1) the termination proceeds from a non-Claymore unit trust
with a similar investment strategy or (2) the redemption proceeds from a
non-Claymore trust if such trust has a similar investment strategy and the
corresponding Claymore trust provides a periodic update of that investment
strategy. To qualify for this sales charge reduction, the termination or
redemption proceeds being used to purchase units of the trust must be no more
than 30 days old. Such purchases entitled to this sales charge reduction may be
classified as "Rollover Purchases."

     Rollover Purchases are also subject to the C&D Fee. See "Expenses of the
Trust" in Part B of the Prospectus.

     EMPLOYEES. We do not charge the portion of the transactional sales fee that
we would normally pay to your financial professional for purchases made by
officers, directors and employees and their family members (spouses, children
and parents) of Claymore and its affiliates, or by registered representatives of
selling firms and their family members (spouses, children and parents). You pay
only the portion of the fee that the sponsor retains. Such purchases are also
subject to the C&D Fee. This discount

                                       12
<Page>

applies during the initial offering period and in the secondary market.

     DIVIDEND REINVESTMENT PLAN. We do not charge any transactional sales fee
when you reinvest distributions from your trust into additional units of the
trust. Since the deferred sales fee is a fixed dollar amount per unit, your
trust must charge the deferred sales fee 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 that will be collected on such units at the time of
reinvestment. The dollar value of these units will fluctuate over time. This
discount applies during the initial offering period and in the secondary market.

     See "Purchase, Redemption and Pricing of Units" in Part B of the prospectus
for more information regarding buying units.

     HOW WE DISTRIBUTE UNITS. We sell units to the public through broker-dealers
and other firms. We pay part of the sales fee you pay to these distribution
firms when they sell units. The distribution fee paid for a given transaction is
as follows:

<Table>
<Caption>
                               CONCESSION PER UNIT:
         PURCHASE AMOUNT/        (AS A % OF PUBLIC
         FORM OF PURCHASE:       OFFERING PRICE):
         -----------------     --------------------
                                     
     Less than $50,000                  2.25%
     $50,000 - $99,999                  2.00
     $100,000 - $249,999                1.75
     $250,000 - $499,999                1.50
     $500,000 - $999,999                1.25
     $1,000,000 or more                 0.75
     Rollover Purchases                 1.30
     Wrap Account and
       Employee Purchases                  0
</Table>

     We apply these amounts as a percent of the unit price per transaction at
the time of the transaction. We also apply the different distribution levels on
a unit basis using a $10 unit equivalent. For example, if a firm executes a
transaction between 10,000 and 24,999 units, it earns 1.75% of the unit price.

     Broker-dealers and other firms that sell units of certain Claymore unit
trusts are eligible to receive additional compensation for volume sales. Such
payments will be in addition to the regular concessions paid to dealer firms as
set forth in the applicable trust's prospectus. The additional concession is
based on total sales of eligible Claymore unit trusts during a calendar quarter
as set forth in the following table:

<Table>

                                    (AS A PERCENTAGE
         PRIMARY OFFERING            OF THE VALUE OF
        PERIOD SALES DURING          UNITS SOLD OVER
         CALENDAR QUARTER              $3 MILLION)

      $3 million                            0%
     $3 million but less than
      $20 million                        0.05
     $20 million or more                 0.10
</Table>

     Eligible unit trusts include all Claymore unit trusts, other than
IQ/Claymore municipal portfolios, sold in the primary market. Dealer firms will
not receive additional compensation for the first $3 million sold in units
during a calendar quarter. For example, if a dealer firm sells $4 million of
eligible units in a calendar quarter, the dealer firm will receive additional
compensation of 0.05% of $1 million. Also, if a dealer firm sells $26 million of
eligible units in a calendar quarter, the dealer firm will receive additional
compensation of 0.10% of $23 million.

                                       13
<Page>

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.

     For the initial quarterly period of the volume concession program (November
1, 2004 through December 31, 2004), the amount of primary market sales required
to qualify for a volume concession and the applicable volume concession will be
prorated to account for the abbreviated measuring period. Claymore reserves the
right to modify or terminate the volume concession program at any time.

     We generally register units for sale in various states in the U.S. We do
not register units for sale in any foreign country. It is your financial
professional's responsibility to make sure that units are registered or exempt
from registration if you are a foreign investor or if you want to buy units in
another 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. For example, we lost the amount set forth in "Trust Portfolio" on the
initial deposit of stocks into the trust.

     See "Purchase, Redemption and Pricing of Units" in Part B of the prospectus
for additional information.

                             HOW TO SELL YOUR UNITS

     You can sell your units on any business day by contacting your financial
professional or, in some cases, the trustee. Unit prices are available daily on
the Internet at www.claymoresecurities.com or through your financial
professional. We often refer to the sale price of units as the "bid price." You
pay any remaining deferred sales fee when you sell or redeem your units. Certain
broker-dealers may charge a transaction fee for processing unit redemptions or
sale requests.

     Until the end of the initial offering period or six months after the
Inception Date, at the discretion of the sponsor, the price at which the Trustee
will redeem units and the price at which the Sponsor may repurchase units
include estimated organization costs. After such period, the amount paid will
not include such estimated organization costs.

     SELLING UNITS. We intend to, but are not obligated to, maintain a secondary
market for units. This means that if you want to sell your units, we may buy
them at the current price which is based on their net asset value. 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 generally 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 unit prices to determine the best price available. We may discontinue
our secondary market at any time without notice. Even if we

                                       14
<Page>

do not make a market, you will be able to redeem your units with the trustee on
any business day for the current price.

     REDEEMING UNITS. You may also be able to redeem your units directly with
the trustee, The Bank of New York, on any day the New York Stock Exchange is
open. The trustee must receive your completed redemption request prior to the
close of the New York Stock Exchange for you to receive the unit price for a
particular day. (For what constitutes a completed redemption request, see
"Purchase, Redemption and Pricing of Units - Redemption" in the Part B of the
prospectus.) If your request is received after that time or is incomplete in any
way, you will receive the next price computed after the trustee receives your
completed request. Rather than contacting the trustee directly, your financial
professional may also be able to redeem your units by using the Investors'
Voluntary Redemptions and Sales (IVORS) automated redemption service offered
through Depository Trust Company.

     If you redeem your units, the trustee will generally send you a payment for
your units no later than three business days after it receives all necessary
documentation.

     You can generally request an in-kind distribution of the stocks underlying
your units if you own units worth at least $25,000 or you originally paid at
least that amount for your units. This option is generally available only for
stocks traded and held in the United States. You may not request this option in
the last five business days of your trust's life. We may modify or discontinue
this option at any time without notice.

     EXCHANGE OPTION. You may be able to exchange your units for units of other
Claymore unit trusts at a reduced sales fee. You can contact your financial
professional or Claymore 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. To
qualify for a reduced sales fee, you must purchase units in a subsequent trust
on the same day that you redeem units of your current trust. We may discontinue
this option at any time.

     For more complete information regarding selling or redeeming your units,
see "Purchase, Redemption and Pricing of Units" in Part B of the prospectus.

                                  DISTRIBUTIONS

     DIVIDENDS. Your trust generally pays dividends from its net investment
income along with any excess capital on each distribution date to unitholders of
record on the preceding record date. You can elect to:

     -    reinvest distributions in additional units of your trust at no fee, or

     -    receive distributions in cash.

     You may change your election by contacting your financial professional or
the trustee. Once you elect to participate in a reinvestment program, the
trustee will automatically reinvest your distributions into additional units at
their net asset value on the distribution date. We waive the sales fee for
reinvestments into units of your trust. We cannot guarantee that units will
always be available for reinvestment. If

                                       15
<Page>

units are unavailable, you will receive cash distributions. We may discontinue
these options at any time without notice.

     In some cases, your trust might pay a special distribution if it holds an
excessive amount of principal 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.

     REINVEST IN YOUR TRUST. You can keep your money working by electing to
reinvest your distributions in additional units of your trust. The easiest way
to do this is to have your financial professional purchase units with one of the
Reinvestment CUSIP numbers listed in the "Investment Summary" section of this
prospectus. You may also make or change your election by contacting your
financial professional or the trustee.

     REPORTS. The trustee will send your financial professional 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 stock evaluations to enable
you to complete your tax forms and audited financial statements for your trust,
if available.

     See "Administration of the Trust" in Part B of the prospectus for
additional information.

                                INVESTMENT RISKS

     ALL INVESTMENTS INVOLVE RISK. This section describes the main risks that
can impact the value of the stocks in your trust. You should understand these
risks before you invest. Recently, equity markets have experienced significant
volatility. If the value of the stocks 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. Market risk is the risk that the value of the stocks will
fluctuate. This could cause the value of your units to fall below your purchase
price. Market value fluctuates in response to various factors. These can include
stock market movements, purchases or sales of securities by the trust,
government policies, litigation, and changes in interest rates, inflation, the
financial condition of the stock's issuer or even perceptions of the issuer.
Even though we carefully supervise your portfolio, you should remember that we
do not manage your portfolio. Your trust will not sell a stock solely because
the market value falls as is possible in a managed fund.

     INFLATION RISK. Inflation risk is the risk that the value of assets or
income from investments will be less in the future as inflation decreases the
value of money.

     CONCENTRATION RISK. When securities in a particular industry make up 25% or
more of a trust, it is said to be "concentrated" in that industry which makes
the trust subject to more market risk. The trust is concentrated in the
securities of _______ companies.

     See "Risk Factors" in Part B of the prospectus for additional information.

                              HOW YOUR TRUST WORKS

     YOUR TRUST. Your trust is a unit investment trust registered under the
Investment Company Act of 1940 and the Securities Act of 1933. We created the
trust under a trust agreement between Claymore Securities, Inc. (as sponsor,
evaluator and supervisor) and The Bank of New York (as trustee). To create your
trust, we deposited contracts to purchase stocks with the trustee along with an
irrevocable letter of credit or other consideration to pay for the stocks. 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.

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

     -    to pay expenses,

     -    to issue additional units or redeem units,

     -    in limited circumstances to protect the trust,

     -    to make required distributions or avoid imposition of taxes on the
          trust, or

     -    as permitted by the trust agreement.

     Your trust will generally reject any offer for securities or property other
than cash in exchange for the stocks in its portfolio. However, if a public
tender offer has been made for a stock or a merger or acquisition has been
announced affecting a stock, your trust may either sell the stock 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 cash proceeds
to unitholders. If your trust receives securities or property other than cash,
it may either hold the securities or property in its portfolio or sell the
securities or property and distribute the proceeds. For example, this could
happen in a merger or similar transaction.

     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 stocks, it will pay brokerage or other acquisition fees. You could
experience a dilution of your investment because of these fees and fluctuations
in stock prices between the time we create units and the time your trust buys
the stocks. When your trust buys or sells stocks, we may direct that it place
orders with and pay brokerage commissions to brokers that sell units or are
affiliated with your trust. We may consider whether a firm sells units of our
trusts when we select firms to handle these transactions.

     TERMINATION OF YOUR TRUST. Your trust will terminate no later than the
termination date listed in the "Investment Summary" section of this prospectus.
The trustee may terminate your trust early if the value of the trust is less
than 20% of the value of the stocks in the trust at the end of the initial
offering period. 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. We may also terminate your
trust in other limited circumstances.

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

                                       17
<Page>

the stocks underlying your units at termination. Please refer to the section
entitled "How to Sell Your Units - Redeeming Units" for information on in-kind
distributions.

     See "Administration of the Trust" in Part B of the prospectus for
additional information.

                               GENERAL INFORMATION

     EUGENE E. PERONI, JR. Mr. Peroni serves as Senior Managing Director, Equity
Research for Claymore Securities, Inc. Mr. Peroni's insights have been published
in the Peroni Report, a strategy letter offering stock market forecasts and
specific stock recommendations for both short and longer-term investments and
Mr. Peroni has selected the popular "Peroni's Top Ten Picks" since 1988.
Mr. Peroni previously served as Managing Director for Equity Research for Nuveen
Investments. Mr. Peroni began training in the field of technical research at age
16 with his father, Eugene E. Peroni, Sr., who founded the Peroni Method more
than 50 years ago. Mr. Peroni learned from his father the importance of a
disciplined "hand-picked" approach to investing, an approach reaffirmed by
volatile markets. Mr. Peroni has more than 25 years of experience in his field.
The Peroni Method uses a bottom-up approach, emphasizing the technical merits of
an individual stock.

     Mr. Peroni regularly appears on CNBC, CBS MarketWatch, PBS Nightly Business
Report, and Bloomberg TV, and is quoted often in such esteemed publications as
The Wall Street Journal, The New York Times and Investors Business Daily.
According to Mr. Peroni, "[a]s surely as the seasons will come and go, financial
markets will continue to fall in and out of favor. Through all of this change it
is rewarding to me to know that my family's method will continue to provide
investors with uncommon insight and unique opportunities."

     The equity universe from which Gene Peroni builds his research library is
comprised of mostly exchange-traded stocks. His library of approximately 1,000
hand-charted stocks is the result of extensive technical research and is
regularly refreshed to include new opportunities gleaned through ticker tape
analysis, news outlets, corporate developments and practical observations.
Careful study and continuous updating of these hand-drawn charts is the
cornerstone of his bottom-up approach.

     Charts with attractive price architecture are noted and stocks are ranked
and screened on a regular basis. Historical characteristics are analyzed for
price and volume shifts and evaluations are made using money flow and relative
strength trends. Sector relative strength is then determined by unbiased
groupings of attractive stocks. Portfolio construction progresses as weightings
are determined by analyzing individual stock price behavior, economic factors,
monetary trends and psychological oscillators. Those stocks with the best
technical characteristics in strong or emerging leadership sectors are
candidates for inclusion in the portfolio while also taking into consideration
appropriate diversification.

     CLAYMORE. Claymore Securities, Inc. specializes in the creation,
development and distribution of investment solutions for advisors and their
valued clients. In November 2001, we changed our name from Ranson & Associates,
Inc. to Claymore Securities, Inc. During our history we have been active in
public and corporate finance and have distributed bonds, mutual funds and unit
trusts in the primary and secondary markets. We are a registered broker-dealer
and member of the National Association of Securities Dealers, Inc. If we fail to
or cannot

                                       18

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. You
can contact us at our headquarters at 2455 Corporate West Drive, Lisle, Illinois
60532 or by using the contacts listed on the back cover of this prospectus.
Claymore personnel, including Mr. Peroni, may from time to time maintain a
position in certain stocks held by the trust.

     Claymore and your trust have adopted a code of ethics requiring Claymore's
employees who have access to information on trust transactions to report
personal securities transactions. The purpose of the code is to avoid potential
conflicts of interest and to prevent fraud, deception or misconduct with respect
to your trust.

     See "Administration of the Trust" in Part B of the prospectus for
additional information.

     THE TRUSTEE. The Bank of New York is the trustee of your trust. It is a
trust company organized under New York law. You can contact the trustee by
calling the telephone number on the back cover of this prospectus or write to
Unit Investment Trust Division, 101 Barclay Street, 20th Fl., New York, New York
10286. We may remove and replace the trustee in some cases without your consent.
The trustee may also resign by notifying Claymore and investors.

     See "Administration of the Trust" in Part B of the prospectus for
additional information.

                                    EXPENSES

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

     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 and evaluator for providing portfolio
supervisory services and for evaluating your portfolio. 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 Claymore unit investment trusts in any
calendar year. All of these fees may adjust for inflation without your approval.

     Your trust will pay a fee to the sponsor for creating and developing the
trust, including determining the trust objective, policies, composition and
size, selecting service providers and information services, and for providing
other similar administrative and ministerial functions. Your trust pays this
"creation and development fee" of $0.05 per unit from the assets of the trust as
of the close of the initial public offering period. The sponsor does not use the
fee to pay distribution expenses or as compensation for sales efforts.

     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
Claymore, 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 may sell securities to pay trust expenses.

     See "Expenses of the Trust" in Part B of the prospectus for additional
information.

                   REPORT OF REGISTERED PUBLIC ACCOUNTING FIRM

UNITHOLDERS
CLAYMORE SECURITIES DEFINED PORTFOLIOS, SERIES 201

We have audited the accompanying statement of financial condition, including the
trust portfolio set forth on page 9 of this prospectus, of Claymore Securities
Defined Portfolios, Series 201, as of __________, 2004, the initial date of
deposit. This 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. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the statement of financial condition. Our procedures included
confirmation with The Bank of New York, Trustee, of cash deposited for the
purchases of securities, as shown in the statement of financial condition as of
__________, 2004. An audit also includes assessing the accounting principles
used and significant estimates made by the trust's sponsor, as well as
evaluating the overall statement of financial condition presentation. 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 Claymore
Securities Defined Portfolios, Series 201 as of __________, 2004, in conformity
with accounting principles generally accepted in the United States.


                                                              Grant Thornton LLP

(1)  Aggregate cost of the securities is based on the closing sale price
     evaluations as determined by the trustee.

(2)  Cash has been deposited with The Bank of New York, trustee, covering the
     trust (aggregating $_______) necessary for the purchase of the 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 the trust.
     These costs have been estimated at $5.00 per 100 units for the trust. A
     distribution will be made as of the close of the initial offering period or
     six months after the initial date of deposit (at the discretion of the
     sponsor) to an account maintained by the trustee from which this obligation
     of the investors will be satisfied. To the extent that actual organization
     costs are greater than the estimated amount, only the estimated
     organization costs added to the Public Offering Price will be deducted from
     the assets of each trust.

(4)  The total transactional sales fee consists of an initial sales fee and a
     deferred sales 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 creation and development fee. On the Inception Date, the total
     transactional sales fee is 2.80% of the Public Offering Price (equivalent
     to 2.881% of the net amount invested) for the trust. The deferred sales fee
     is equal to $0.180 per unit.

(5)  The aggregate cost to investors includes the applicable transactional sales
     fee assuming no reduction of transactional sales fees for quantity
     purchases.

(6)  Each trust is committed to pay a creation and development fee of $5.00 per
     100 units at the close of the initial public offering period.

GENERAL INFORMATION

     Each trust is one of a series of separate unit investment trusts created
under the name Claymore Securities Defined Portfolios and registered under the
Investment Company Act of 1940 and the Securities Act of 1933. 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 Claymore Securities, Inc. (as sponsor, evaluator and supervisor)
and The Bank of New York (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. After your trust is created, the sponsor may deposit
additional securities in the trust, contracts to purchase additional securities
along with cash (or a bank letter of credit in lieu of cash) to pay for such
contracted securities or cash (including a letter of credit) with instructions
to purchase additional securities. Such additional deposits will be in amounts
which will seek to maintain, for the first 90 days, as closely as possible the
same original percentage relationship among the number of shares of each
security in the trust established by the initial deposit of securities and,
thereafter, the same percentage relationship that existed on such 90th day. If
the sponsor deposits cash, 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 cash
deposit and the purchase of the securities and because the trust will pay the
associated brokerage fees.

     A trust consists of (a) the securities listed under "Trust 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 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 charge attributable to such failed contract to all
unitholders on the next distribution date.

INVESTMENT POLICIES

     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 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 sponsor 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 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, the trustee shall 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. Proceeds
from the sale of securities (or any securities or other property received by the
trust in exchange for securities) are credited to the Capital Account for
distribution to unitholders or to meet redemptions.

     Except as stated in the trust agreement, or in the prospectus, the
acquisition by the trust of any securities other than the portfolio securities
is prohibited. The trustee may sell securities, designated by the sponsor, from
the trust for

                                        2
<Page>

the purpose of redeeming units of a trust tendered for redemption and the
payment of expenses and for such other purposes as permitted under the trust
agreement.

     Notwithstanding the foregoing, the trustee is authorized to reinvest any
funds held in the Capital or Income Accounts, pending distribution, in U.S.
Treasury obligations which mature on or before the next applicable distribution
date. Any obligations so acquired must be held until they mature and proceeds
therefrom may not be reinvested.

     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 in the prospectus or in the trust
agreement, the acquisition by a trust of any securities other than the portfolio
securities is prohibited. The trustee may sell securities from a trust for
limited purposes, including redeeming units tendered for redemption and the
payment of expenses.

STOCK DESCRIPTIONS

     The stocks of the following companies are included in the trust portfolio:


RISK FACTORS

     STOCKS. An investment in units of a trust should be made with an
understanding of the risks inherent in an investment in equity securities,
including the risk that the financial condition of issuers of the securities may
become impaired or that the general condition of the stock market may worsen
(both of which may contribute directly to a decrease in the value of the
securities and thus, in the value of the units) or the risk that holders of
common stock have a right to receive payments from the issuers of those stocks
that is generally inferior to that of creditors of, or holders of debt
obligations issued by, the issuers and that the rights of holders of common
stock generally rank inferior to the rights of holders of preferred stock.
Common stocks are especially susceptible to general stock market movements and
to volatile increases and decreases in value as market confidence in and
perceptions of the issuers change. These perceptions are based on unpredictable
factors including expectations regarding government, economic, monetary and
fiscal policies, inflation and interest rates, economic expansion or
contraction, and global or regional political, economic or banking crises.

     Holders of common stock incur more risk than the holders of preferred
stocks and debt obligations because common stockholders, as owners of the
entity, have generally inferior rights to receive payments from the issuer in
comparison with the rights of creditors of, or holders of debt obligations or
preferred stock issued by the issuer. Holders of common stock of the type held
by a trust have a right to receive dividends only when and if, and in the
amounts, declared by the issuer's board of directors and to participate in
amounts available for distribution by the issuer only after all other claims on
the issuer have been paid or provided for. By contrast, holders of preferred
stock have the right to receive dividends at a fixed rate when and as declared
by the issuer's board of directors, normally on a cumulative basis, but do not
participate in other amounts available for distribution by the issuing
corporation. Cumulative preferred stock dividends must be paid before common
stock dividends and any cumulative preferred stock dividend omitted is added to
future dividends payable to the holders of cumulative preferred stock. Preferred
stocks are also entitled to rights on liquidation which are senior to those of
common stocks. Moreover, common stocks do not represent an obligation of the
issuer and therefore do not offer any assurance of income or provide the degree
of protection of capital debt securities. Indeed, the issuance of debt
securities or even preferred stock will create prior claims for payment of
principal, interest, liquidation preferences and dividends which could adversely
affect the ability and inclination of the issuer to declare or pay dividends on
its common stock or the rights of holders of common stock with respect to assets
of the issuer upon liquidation or bankruptcy. Further, unlike debt securities
which typically have a stated principal

                                        3
<Page>

amount payable at maturity (whose value, however, will be subject to market
fluctuations prior thereto), common stocks have neither a fixed principal amount
nor a maturity and have values which are subject to market fluctuations for as
long as the stocks remain outstanding. The value of the securities in a
portfolio thus may be expected to fluctuate over the entire life of a trust to
values higher or lower than those prevailing at the time of purchase.

     The sponsor's buying and selling of the securities, especially during the
initial offering of units of the trust or to satisfy redemptions of units may
impact upon the value of the underlying securities and the units. The
publication of the list of the securities selected for the trust may also cause
increased buying activity in certain of the stocks comprising the portfolio.
After such announcement, investment advisory and brokerage clients of the
sponsor and its affiliates may purchase individual securities appearing on the
list during the course of the initial offering period or may purchase warrants
issued by the sponsor or its affiliates which are based on the performance of
the securities on the list. The sponsor or its affiliates may also purchase
securities as a hedge against its risk on the warrants (although generally the
sponsor and its affiliates will not purchase securities for their own account
until after the trust portfolio has been acquired). Such buying activity in the
stock of these companies or issuance of the warrants prior to the purchase of
the securities by the trust may cause the trust to purchase stocks at a higher
price than those buyers who effect purchases by the trust.

     FIXED PORTFOLIO. Investors should be aware that the trust is not "managed"
and as a result, the adverse financial condition of a company will not result in
the elimination of its securities from the portfolio of the trust except under
extraordinary circumstances. Investors should note in particular that the
securities were selected on the basis of the criteria set forth in the
prospectus and that the trust may continue to purchase or hold securities
originally selected through this process even though the evaluation of the
attractiveness of the securities may have changed. A number of the securities in
the trust may also be owned by other clients of the sponsor. However, because
these clients may have differing investment objectives, the sponsor may sell
certain securities from those accounts in instances where a sale by the trust
would be impermissible, such as to maximize return by taking advantage of market
fluctuations. In the event a public tender offer is made for a security or a
merger or acquisition is announced affecting a security, the sponsor may
instruct the trustee to tender or sell the security on the open market when, in
its opinion, it is in the best interest of the unitholders of the unit to do so.
Although the portfolio is regularly reviewed and evaluated and the sponsor may
instruct the trustee to sell securities under certain limited circumstances,
securities will not be sold by the trust to take advantage of market
fluctuations or changes in anticipated rates of appreciation. As a result, the
amount realized upon the sale of the securities may not be the highest price
attained by an individual security during the life of the trust. The prices of
single shares of each of the securities in the trust vary widely, and the effect
of a dollar of fluctuation, either higher or lower, in stock prices will be much
greater as a percentage of the lower-price stocks' purchase price than as a
percentage of the higher-price stocks' purchase price.

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

     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) with instructions to purchase
additional securities, in such trust and the issuance of a corresponding number
of additional units. If the sponsor deposits cash, existing and new investors
may experience a dilution of their investments and a reduction in their
anticipated income because of fluctuations in the prices of the securities
between the time of the cash deposit and the purchase of the securities and
because a trust will pay the associated brokerage fees. To minimize this effect,
the trusts will attempt to purchase the securities as close to the evaluation
time or as close to the evaluation prices as possible.

                                        4
<Page>

     Some of the securities may have limited trading volume. The trustee, with
directions from the sponsor, will endeavor to purchase securities with deposited
cash as soon as practicable reserving the right to purchase those securities
over the 20 business days following each deposit in an effort to reduce the
effect of these purchases on the market price of those stocks. This could,
however, result in the trusts' failure to participate in any appreciation of
those stocks before the cash is invested. If any cash remains at the end of this
period (and such date is within the 90-day period following the inception date)
and cannot be invested in one or more stocks, at what the sponsor considers
reasonable prices, it intends to use that cash to purchase each of the other
securities in the original proportionate relationship among those securities.
Similarly, at termination of the trust, the sponsor reserves the right to sell
securities over a period of up to 20 business days to lessen the impact of its
sales on the market price of the securities. The proceeds received by
unitholders following termination of the trust will reflect the actual sales
proceeds received on the securities, which will likely differ from the closing
sale price on the termination date.

     LITIGATION AND LEGISLATION. At any time litigation may be initiated on a
variety of grounds, or legislation may be enacted with respect to the securities
in a trust or the issuers of the securities. There can be no assurance that
future litigation or legislation will not have a material adverse effect on the
trust or will not impair the ability of issuers to achieve their business goals.

     TOBACCO INDUSTRY. Certain of the issuers of securities in the trust may be
involved in the manufacture, distribution and sale of tobacco products. Pending
litigation proceedings against such issuers in the United States and abroad
cover a wide range of matters including product liability and consumer
protection. Damages claimed in such litigation alleging personal injury (both
individual and class actions), and in health cost recovery cases brought by
governments, labor unions and similar entities seeking reimbursement for health
care expenditures, aggregate many billions of dollars.

     In November 1998, certain companies in the U.S. tobacco industry entered
into a negotiated settlement with several states which would result in the
resolution of significant litigation and regulatory issues affecting the tobacco
industry generally. The proposed settlement, while extremely costly to the
tobacco industry, would significantly reduce uncertainties facing the industry
and increase stability in business and capital markets. Future litigation and/or
legislation could adversely affect the value, operating revenues and financial
position of tobacco companies. The sponsor is unable to predict the outcome of
litigation pending against tobacco companies or how the current uncertainty
concerning regulatory and legislative measures will ultimately be resolved.
These and other possible developments may have a significant impact upon both
the price of such securities and the value of units of a trust containing such
securities.

     CONSUMER PRODUCTS. Certain securities in a trust may be securities of
issuers in the consumer products industry. An investment in such securities
should be made with an understanding of the problems and risks inherent in an
investment in the consumer products industry in general. These include the
cyclicality of revenues and earnings, changing consumer demands, regulatory
restrictions, product liability litigation and other litigation resulting from
accidents, extensive competition (including that of low-cost foreign
competition), unfunded pension fund liabilities and employee and retiree benefit
costs and financial deterioration resulting from leveraged buy-outs, takeovers
or acquisitions. In general, expenditures on consumer products will be affected
by the economic health of consumers. A weak economy with its consequent effect
on consumer spending would have an adverse effect on consumer products
companies. Other factors of particular relevance to the profitability of the
industry are the effects of increasing environmental regulation on packaging and
on waste disposal, the continuing need to conform with foreign regulations
governing packaging and the environment, the outcome of trade negotiations and
the effect on foreign subsidies and tariffs, foreign exchange rates, the price
of oil and its effect on energy costs, inventory cutbacks by retailers,
transportation and distribution costs, health concerns relating to the
consumption of certain products, the effect of demographics on consumer demand,
the availability and cost of raw materials and the ongoing need to develop new
products and to improve productivity.

     HEALTHCARE INDUSTRY. Certain securities in the trust may be securities of
companies involved in advanced medical devices and instruments, drugs and
biotech, healthcare/managed care, hospital management/health services and
medical supplies, each of which have potential risks unique to their sector of
the healthcare field. These companies are subject to governmental regulation of
their products and services, a factor which could have a significant and
possibly

                                        5
<Page>

unfavorable effect on the price and availability of such products or services.
Furthermore, such companies face the risk of increasing competition from new
products or services, generic drug sales, the termination of patent protection
for drug or medical supply products and the risk that technological advances
will render their products obsolete. The research and development costs of
bringing a drug to market are substantial, and include lengthy governmental
review processes with no guarantee that the product will ever come to market.
Many of these companies may have losses and may not offer certain products for
several years. Such companies may also have persistent losses during a new
product's transition from development to production, and revenue patterns may be
erratic. In addition, healthcare facility operators may be affected by events
and conditions including among other things, demand for services, the ability of
the facility to provide the services required, physicians' confidence in the
facility, management capabilities, competition with other hospitals, efforts by
insurers and governmental agencies to limit rates, legislation establishing
state rate-setting agencies, expenses, government regulation, the cost and
possible unavailability of malpractice insurance and the termination or
restriction of governmental financial assistance, including that associated with
Medicare, Medicaid and other similar third party payor programs.

     As the population of the United States ages, the companies involved in the
healthcare field will continue to search for and develop new drugs, medical
products and medical services through advanced technologies and diagnostics. On
a worldwide basis, such companies are involved in the development and
distributions of drugs, vaccines, medical products and medical services. These
activities may make the healthcare and medical services sector very attractive
for investors seeking the potential for growth in their investment portfolio.
However, there are no assurances that a trust's objectives will be met.

     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 pre-paid healthcare plans. The sponsor is
unable to predict the effect of any of these proposals, if enacted, on the
issuers of securities in a trust.

ADMINISTRATION OF THE TRUST

     DISTRIBUTIONS TO UNITHOLDERS. Income received by a trust is credited by the
trustee to the Income Account of the trust: Other receipts are credited to the
Capital Account of a trust. Income received by a trust will be distributed on or
shortly after the distribution dates each year shown in the prospectus on a pro
rata basis to unitholders of record as of the preceding record date shown in the
prospectus. 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 at least annually to the
unitholders then of record. 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
100 units. 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 trustee is authorized to reinvest any
funds held in the Capital or Income Accounts, pending distribution, in U.S.
Treasury obligations which mature on or before the next applicable distribution
date. Any obligations so acquired must be held until they mature and proceeds
therefrom may not be reinvested.

     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 such portion of the unitholders' pro rata share of
the dividend distributions then held in the Income Account 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

                                        6
<Page>

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 such
notice is provided by the selling broker-dealer.

     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 a 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 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 elect to have distributions of
capital (including capital gains, if any) or dividends or both automatically
invested into additional units of their trust without a sales fee.

     Your trust will pay any deferred sales fee per unit regardless of any sales
fee discounts. However, if you elect to have distributions on your units
reinvested into additional units of your trust, you will be credited the amount
of any remaining deferred sales charge on such additional units at the time of
reinvestment.

     Unitholders who are receiving distributions in cash may elect to
participate in distribution reinvestment by filing with the Program Agent an
election to have such distributions reinvested without charge. Such election
must be received by the Program Agent at least ten days prior to the record date
applicable to any distribution in order to be in effect for such record date.
Any such election shall remain in effect until a subsequent notice is received
by the Program Agent.

     The Program Agent is The Bank of New York. All inquiries concerning
participating in distribution reinvestment should be directed to The Bank of
New York at its Unit Investment Trust Division office.

     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 will not be audited annually unless the sponsor
determines that such an audit would be in the best interest of the unitholders
of the trust. If an audit is conducted, it will be done at the related trust's
expense, by independent public accountants designated by the sponsor. 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, generally setting forth for the trust:

(A)  As to the Income Account:

          (1)  Income received;

          (2)  Deductions for applicable taxes and for fees and expenses of the
               trust and for redemptions of units, if any; and

          (3)  The balance remaining after such distributions and deductions,
               expressed in each case both as a total dollar amount and as a
               dollar amount representing the pro rata share of each unit
               outstanding on the last business day of such calendar year; and

(B)  As to the Capital Account:

          (1)  The dates of disposition of any securities and the net proceeds
               received therefrom;

                                        7
<Page>

          (2)  Deductions for payment of applicable taxes and fees and expenses
               of the trust held for distribution to unitholders of record as of
               a date prior to the determination; and

          (3)  The balance remaining after such distributions and deductions
               expressed both as a total dollar amount and as a dollar amount
               representing the pro rata share of each unit outstanding on the
               last business day of such calendar year; and

(C)  The following information:

          (1)  A list of the securities as of the last business day of such
               calendar year;

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

          (3)  The redemption price based on the last evaluation made during
               such calendar year;

          (4)  The amount 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 each such distribution.

     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 by the
trustee and the sponsor without the consent of any of the unitholders: (1) to
cure any ambiguity or to correct or supplement any provision which may be
defective or inconsistent; (2) to change any provision thereof as may be
required by the Securities and Exchange Commission or any successor governmental
agency; or (3) to make such provisions as shall not adversely affect the
interests of the unitholders. The trust agreement with respect to any trust may
also be amended in any respect by the sponsor and the trustee, or any of the
provisions thereof may be waived, with the consent of the holders of units
representing 66 2/3% of the units then outstanding of the trust, provided that
no such amendment or waiver will reduce the interest of any unitholder thereof
without the consent of such unitholder or reduce the percentage of units
required to consent to any such amendment or waiver without the consent of all
unitholders of the trust. In no event shall the trust agreement be amended to
increase the number of units of a trust issuable thereunder or to permit the
acquisition of any securities in addition to or in substitution for those
initially deposited in the trust, except in accordance with the provisions of
the trust agreement. The trustee shall promptly 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 set forth in Part A of the prospectus. If the value of a trust shall be
less than the applicable minimum value stated in the prospectus (generally 20%
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.

     Beginning nine business days prior to, but no later than, the mandatory
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.

                                        8

     The trustee will attempt to sell the securities as quickly as it can 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 five days prior to termination of certain trusts, the trustee
will notify unitholders of the termination and provide a form allowing
qualifying unitholders to elect an in-kind distribution (a "DISTRIBUTION IN
KIND"). A unitholder who owns the minimum number of units shown in Part A of the
prospectus may request a Distribution In Kind from the trustee instead of cash.
The trustee will make a Distribution In Kind 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 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 Distribution In
Kind to facilitate the distribution of whole shares. The sponsor may terminate
the Distribution In Kind option at any time upon notice to the unitholders.
Special federal income tax consequences will result if a unitholder requests a
Distribution In Kind.

     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 (upon surrender
for cancellation of certificates for units, if issued) their pro rata share of
the balances remaining in the Income and Capital Accounts of the trust.

     The sponsor currently intends, but is not obligated, to offer for sale
units of a subsequent series of certain trusts at approximately one year after
the inception date of such trusts. If the sponsor does offer such units for
sale, unitholders may be given the opportunity to purchase such units at a
public offering price which 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, a trust company organized
under the laws of New York. The Bank of New York has its Unit Investment Trust
Division offices at 101 Barclay Street, 20th Fl., New York, New York 10286,
telephone 1-800-701-8178. The Bank of New York is subject to supervision and
examination by the Superintendent of Banks of the State of New York and the
Board of Governors of the Federal Reserve System, and its deposits are insured
by the Federal Deposit Insurance Corporation to the extent permitted by law.

     The 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

                                        9
<Page>

such resignation is obligated to appoint a successor trustee promptly. If, upon
such resignation, no successor trustee has been appointed and has accepted the
appointment within thirty days after notification, the retiring trustee may
apply to a court of competent jurisdiction for the appointment of a successor.
The sponsor may at any time remove the trustee, with or without cause, and
appoint a successor trustee as provided in the trust agreement. 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. Claymore Securities, Inc. specializes in the creation,
development and distribution of investment solutions for advisors and their
valued clients. Claymore Securities, Inc. was created as Ranson & Associates,
Inc., in 1995 and is the successor sponsor to unit investment trusts formerly
sponsored by EVEREN Unit Investment Trusts, a service of EVEREN Securities, Inc.
Claymore Securities, Inc. is also the sponsor and successor sponsor of Series of
Ranson Unit Investment Trusts and The Kansas Tax-Exempt Trust and Multi-State
Series of The Ranson Municipal Trust. On October 29, 2001, Ranson & Associates,
Inc. was acquired by Claymore Group LLC. The sale to Claymore Group LLC was
financed by a loan from The Bank of New York, the trustee. In November 2001, the
sponsor changed its name from Ranson & Associates, Inc. to Claymore Securities,
Inc. Claymore Securities, Inc. has been active in public and corporate finance
and has sold bonds and unit investment trusts and maintained secondary market
activities relating thereto. At present, Claymore Securities, Inc. which is a
member of the National Association of Securities Dealers, Inc., is the sponsor
to each of the above-named unit investment trusts. The sponsor's offices are
located at 2455 Corporate West Drive, Lisle, Illinois 60532 and at 101 W. Elm
Street, Suite 310, Conshohoken, Pennsylvania 19428.

     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, or (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 SUPERVISOR AND THE EVALUATOR. Claymore Securities, Inc., the sponsor,
also serves as evaluator and supervisor. The evaluator and supervisor may resign
or be removed by the trustee in which event the 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 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
registration or removal and appointment shall be mailed by the trustee to each
unitholder.

     LIMITATIONS ON LIABILITY. The sponsor is liable for the performance of its
obligations arising from its 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

                                       10
<Page>

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 does not charge a trust an annual advisory fee. 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 and/or its affiliates do, also, receive an
annual fee as set forth in Part A of the prospectus for maintaining surveillance
over the portfolio and for performing certain administrative services for the
Trust (the "SPONSOR'S SUPERVISORY FEE"). In providing such supervisory services,
the sponsor may purchase research from a variety of sources, which may include
dealers of the trusts. If so provided in Part A of the prospectus, the sponsor
may also receive an annual fee for providing bookkeeping and administrative
services for a trust (the "BOOKKEEPING AND ADMINISTRATIVE FEE"). Such services
may include, but are not limited to, the preparation of various materials for
unitholders and providing account information to the unitholders. If so provided
in Part A of the prospectus, the evaluator may also receive an annual fee for
performing evaluation services for the trusts (the "EVALUATOR'S FEE"). In
addition, if so provided in Part A of the prospectus, a trust may be charged an
annual licensing fee to cover licenses for the use of service marks, trademarks,
trade names and intellectual property rights and/or for the use of databases and
research. The trust will bear all operating expenses. Estimated annual trust
operating expenses are as set forth in Part A of the prospectus; if actual
expenses are higher than the estimate, the excess will be borne by the trust.
The estimated expenses include listing fees but do not include the brokerage
commissions and other transactional fees payable by the trust in purchasing and
selling securities.

     The trustee receives for its services that fee set forth in Part A of the
prospectus. The trustee's fee, which is calculated monthly, is based on the
largest number of units of a trust outstanding at any time during the primary
offering period. After the primary offering period, the fee shall accrue daily
and be based on the number of units outstanding on the first business day of
each calendar year in which the fee is calculated or the number of units
outstanding at the end of the primary offering period, as appropriate. The
Sponsor's Supervisory Fee, the Bookkeeping and Administrative Fee and the
Evaluator's Fee are calculated monthly and are based on the largest number of
units outstanding at any time during the period for which such compensation is
being computed. 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. In
addition, the Sponsor's Supervisory Fee, Bookkeeping and Administrative Fee,
Evaluator's Fee and the Trustee's Fee may be adjusted in accordance with the
cumulative percentage increase of the United States Department of Labor's
Consumer Price Index entitled "All Services Less Rent" since the establishment
of the trust. In addition, with respect to any fees payable to the sponsor or an
affiliate of the sponsor for providing bookkeeping and other administrative
services, supervisory services and evaluation services, such individual fees may
exceed the actual costs of providing such services for a trust, but at no time
will the total amount received for such services, in the aggregate, rendered to
all unit investment trusts of which Claymore is the sponsor in any calendar year
exceed the actual cost to the sponsor or its affiliates of supplying such
services, in the aggregate, in such year.

     The trust will also will pay a fee to the sponsor for creating and
developing the trust, including determining the trust objective, policies,
composition and size, selecting service providers and information services, and
for providing other similar administrative and ministerial functions. Your trust
pays this "creation and development fee" as a fixed

                                       11
<Page>

dollar amount at the close of the initial offering period. The sponsor does not
use the fee to pay distribution expenses or as compensation for sales efforts.

     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, 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 the administration of the trust not resulting from
gross negligence, bad faith or willful misconduct on its part; (f)
indemnification of the sponsor for any loss, liability or expense incurred in
acting in that capacity without gross negligence, bad faith or willful
malfeasance or its reckless disregard for its obligations under the trust
agreement; (g) any offering costs incurred after the end of the initial offering
period; and (h) 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. Since the
securities are all stocks, and the income stream produced by dividend payments,
if any, is unpredictable, the sponsor cannot provide any assurance that
dividends will be sufficient to meet any or all expenses of a 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. It is expected that the income stream produced by dividend payments
may be insufficient to meet the expenses of a trust and, accordingly, it is
expected that securities will be sold to pay all of the fees and expenses of the
trust.

     The trust shall also bear the expenses associated with updating the trust's
registration statement and maintaining registration or qualification of the
units and/or a trust under federal or state securities laws subsequent to
initial registration. Such expenses shall include legal fees, accounting fees,
typesetting fees, electronic filing expenses and regulatory filing fees. The
expenses associated with updating registration statements have been historically
paid by a unit investment trust's sponsor.

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 supervisor to specify minimum amounts (such
as 100 shares) in which blocks of securities are to be sold. In effecting
purchases and sales of a trust's portfolio securities, the sponsor may direct
that orders be placed with and brokerage commissions be paid to brokers,
including brokers which may be affiliated with the 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 (which is based on the aggregate underlying value of the securities in the
trust and includes the initial sales fee plus a pro rata share of any
accumulated amounts in the accounts of the trust). 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 creation and development fee ("C&D FEE").
The maximum sales fee is set forth in Part A of the prospectus. The deferred
sales fee and the C&D Fee will be collected as described in this prospectus.
Units purchased subsequent to the initial deferred sales fee payment will be
subject to the initial sales fee, the remaining deferred sales fee payments and
the C&D Fee. 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. 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
("ORGANIZATION COSTS"). These organization 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, at the discretion of the
sponsor. 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

                                       12
<Page>

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 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 properly received at or prior to
the close of trading on the New York Stock Exchange on each such day. Orders
received by the trustee, sponsor or any dealer for purchases, sales or
redemptions after that time, or on a day when the New York Stock Exchange is
closed, will be held until the next determination of price.

     The value of the securities is determined on each business day by the
evaluator based on the closing sale prices on a national securities exchange or
the Nasdaq National Market System or by taking into account the same factors
referred to under "Computation of Redemption Price."

     PUBLIC DISTRIBUTION OF UNITS. During the initial offering period, units of
a trust will be distributed to the public at the public offering price thereof.
Upon the completion of the initial offering, units which remain unsold or which
may be acquired in the secondary market may be offered at the public offering
price determined in the manner provided above.

     The sponsor intends to qualify units of a trust 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. Broker-dealers and
others will be allowed a concession or agency commission in connection with the
distribution of units during the initial offering period as set forth in the
prospectus.

     Certain commercial banks may be making units of a trust available to their
customers on an agency basis. Furthermore, as a result of certain legislative
changes effective November 1999, banks are no longer prohibited from certain
affiliations with securities firms. This new legislation grants banks new
authority to conduct certain authorized activity, such as sales of Units,
through financial subsidiaries. A portion of the sales charge discussed above is
retained by or remitted to the banks or their financial subsidiaries for these
agency and brokerage transactions. The sponsor reserves the right to change the
concessions or agency commissions set forth in the prospectus from time to time.
In addition to such concessions or agency commissions, the sponsor may, from
time to time, pay or allow additional concessions or agency commissions, in the
form of cash or other compensation, to dealers employing registered
representatives who sell, during a specified time period, a minimum dollar
amount of units of unit investment trusts underwritten by the sponsor. At
various times the sponsor may implement programs under which the sales force of
a broker or dealer may be eligible to win nominal awards for certain sales
efforts, or under which the sponsor will reallow to any such broker or dealer
that sponsors sales contests or recognition programs conforming to criteria
established by the sponsor, or participates in sales programs sponsored by the
sponsor, an amount not exceeding the total applicable sales charges on the sales
generated by such person at the public offering price during such programs.
Also, the sponsor in its discretion may from time to time pursuant to objective
criteria established by the sponsor pay fees to qualifying brokers or dealers
for certain services or activities which are primarily intended to result in
sales of units of a trust. Such payments are made by the sponsor out of its own
assets, and not out of the assets of any trust. These programs will not change
the price unitholders pay for their units or the amount that a trust will
receive from the units sold. The difference between the discount and the sales
charge will be retained by the sponsor.

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

     SPONSOR PROFITS. The sponsor will receive gross sales fees equal to the
percentage of the public offering price of the units of a trust described in the
prospectus. In addition, the sponsor may realize a profit (or sustain a loss) as
of the date a trust is created resulting from the difference between the
purchase prices of the securities to the sponsor and the cost of such securities
to the trust. Thereafter, on subsequent deposits the sponsor may realize profits
or sustain losses from such deposits. The sponsor may realize additional profits
or losses during the initial offering period on unsold units as a result of
changes in the daily market value of the securities in the trust.

                                       13
<Page>

     MARKET FOR UNITS. After the initial offering period, the sponsor may
maintain a market for units of a trust offered hereby and continuously offer to
purchase said units at prices, determined by the evaluator, based on the value
of the underlying securities. 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. 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 in
the city of New York. Unitholders must sign the request, and such transfer
instrument, exactly as their names appear on the records of the trustee. If the
amount of the redemption is $500 or less and the proceeds are payable to the
unitholder(s) of record at the address of record, no signature guarantee is
necessary for redemptions by individual account owners (including joint owners).
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 third business
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 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. 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 unpaid dividends 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 from the trustee in lieu of cash redemption. A unitholder may request a
Distribution In Kind 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 is (1) entitled
to receive at least $25,000 of proceeds as part of his or her distribution or
if he paid at least $25,000 to acquire the units being tendered and (2) the
unitholder has elected to redeem at least five days prior to the termination
of the trust. If the unitholder meets these requirements, a Distribution In
Kind will be made by the trustee

                                       14
<Page>

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
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 right of redemption may be suspended and payment postponed for more
than three business days following the day on which tender for redemption is
made (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 per unit (as well as
the secondary market public offering price) will generally be determined on the
basis of the last sale price of the securities in a trust. The redemption price
per unit is the pro rata share of each unit in a trust determined generally on
the basis of (i) the cash on hand in the trust or moneys in the process of being
collected and (ii) the value of the securities in the trust less (a) amounts
representing taxes or other governmental charges payable out of the trust, (b)
any amount owing to the trustee for its advances and (c) the accrued expenses or
remaining deferred sales fees of the trust. During the initial offering period,
the redemption price and the secondary market repurchase price will also include
estimated organizational costs. The evaluator may determine the value of the
securities in the trust in the following manner: if the securities are listed on
a national or foreign securities exchange or the Nasdaq National Market System,
such evaluation shall generally be based on the last available sale price on or
immediately prior to the Evaluation Time on the exchange or Nasdaq National
Market System which is the principal market therefor, which shall be deemed to
be the New York Stock Exchange if the securities are listed thereon (unless the
evaluator deems such price inappropriate as a basis for evaluation) or, if there
is no such available sale price on such exchange, at the last available bid
prices (offer prices for primary market purchases) of the securities. Securities
not listed on the New York Stock Exchange but principally traded on the Nasdaq
National Market System will be valued at the Nasdaq National Market System's
official closing price. If the securities are not so listed or, if so listed,
the principal market therefor is other than on such exchange or there is no such
available sale price on such exchange, such evaluation shall generally be based
on the following methods or any combination thereof whichever the evaluator
deems appropriate: (i) on the basis of the current bid price (offer prices for
primary market purchases) for comparable securities (unless the evaluator deems
such price inappropriate as a basis for evaluation), (ii) by determining the
valuation of the securities on the bid side (offer side for primary market
purchases) of the market by appraisal or (iii) by any combination of the above.
If the trust holds securities denominated in a currency other than U.S. dollars,
the evaluation of such security shall be converted to U.S. dollars based on
current bid side (offer side for primary market purchases) exchange rates
(unless the evaluator deems such prices inappropriate as a basis for valuation).

     RETIREMENT PLANS. A trust may be well 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 to $250. Fees and charges with
respect to such plans may vary.

     OWNERSHIP OF UNITS. Ownership of units will not be evidenced by
certificates. All evidence of ownership of units will be recorded in book entry
form either at Depository Trust Company("DTC") through an investor's brokers'
account or through registration of the units on the books of the trustee. Units
held through DTC will be registered in the nominee name of Cede & Co. Individual
purchases of beneficial ownership interest in the trust will be made in book
entry form through DTC or the trustee. Ownership and transfer of units will be
evidenced and accomplished by book entries made by DTC and its participants if
the units are evidenced at DTC, or otherwise will be evidenced and accomplished
by book entries made by the trustee. DTC will record ownership and transfer of
the units among DTC participants and forward all notices and credit all payments
received in respect of the units held by the DTC participants. Beneficial owners
of units will receive written confirmation of their purchases and sale from the
broker dealer or bank from whom their purchase was made. Units are transferable
by making a written request properly accompanied by a written instrument or
instruments of transfer which should be sent registered or certified mail for
the protection of the unitholder. Unitholders must sign such written request
exactly as their names appear on the records of the trust. The signatures must
be guaranteed by a participant in the STAMP or such other signature guaranty
program in addition to, or in substitution for, STAMP, as may be acceptable by
the trustee.

     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.

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 or
foreign taxes. As with any investment, you should consult your own tax
professional about your particular consequences. In addition, the Internal
Revenue Service issued new withholding and reporting regulations effective
January 1, 2001. Foreign investors should consult their own tax advisors
regarding the tax consequences of these regulations.

     In the opinion of Chapman and Cutler LLP, counsel for the trust, under
existing law:

     TRUST STATUS. 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 the securities and other assets held by the trust, 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 security when such income would
be considered to be received by you if you directly owned the trust's assets.
This is true even if you elect to have your distributions automatically
reinvested into additional units. In addition, the income from the trust which
you must take into account for federal income tax purposes is not reduced by
amounts used to pay trust expenses (including the deferred sales charge, if
any).

     YOUR TAX BASIS AND INCOME OR LOSS UPON DISPOSITION. If the trust disposes
of securities, 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

                                       16
<Page>

or loss. To determine the amount of this gain or loss, you must subtract your
tax basis in the related securities from your share of the total amount received
in the transaction. You can generally determine your initial tax basis in each
security or other trust asset by apportioning the cost of your units, generally
including sales charges, among each security or other trust asset ratably
according to their value on the date you purchase your units. In certain
circumstances, however, you may have to adjust your tax basis after you purchase
your units (for example, in the case of certain dividends that exceed a
corporation's accumulated earnings and profits).

     Under the recently enacted "Jobs and Growth Tax Relief Reconciliation Act
of 2003" (the "TAX ACT"), if you are an individual, the maximum marginal federal
tax rate for net capital gain is generally 15% (generally 5% for certain
taxpayers in the 10% and 15% tax brackets). These new capital gains rates are
generally effective for taxable years ending on or after May 6, 2003 and
beginning before January 1, 2009. However, special effective date provisions are
set forth in the Tax Act. For example, there are special transition rules
provided with respect to gain properly taken into account for the portion of the
taxable year before May 6, 2003.

     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 ON STOCKS. Certain dividends received with respect to the
Securities may qualify to be taxed at the same new rates that apply to net
capital gain (as discussed above), provided certain holding requirements are
satisfied. These special rules relating to the taxation of dividends at capital
gains rates generally apply to taxable years beginning after December 31, 2002
and beginning before January 1, 2009.

     ROLLOVERS. If you elect to have your proceeds from the trust rolled over
into the next series of the 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 the 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 securities or other trust assets under the wash sale provisions of the
Internal Revenue Code.

     DISTRIBUTION IN KIND. Under certain circumstances, as described in this
prospectus, you may request a Distribution In Kind when you redeem your units or
at the trust's termination. By electing to receive a Distribution In Kind, you
will receive whole shares of stock plus, possibly, cash.

     You will not recognize gain or loss if you only receive securities in
exchange for your pro rata portion of the securities held by the trust. However,
if you also receive cash in exchange for a trust asset or a fractional share of
a security held by the trust, 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 share.

     LIMITATIONS ON THE DEDUCTIBILITY OF TRUST EXPENSES. Generally, for federal
income tax purposes, you must take into account your full pro rata share of the
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 the trust to the same
extent as if you directly paid the expense. You may, however, be required to
treat some or all of the expenses of the trust as miscellaneous itemized
deductions. Individuals may only deduct certain miscellaneous itemized
deductions to the extent they exceed 2% of adjusted gross income.

     FOREIGN, STATE AND LOCAL TAXES. Distributions by the trust that are treated
as U.S. source income (e.g., dividends received on securities of domestic
corporations) will generally be subject to U.S. income taxation and withholding
in the case of units held by non-resident alien individuals, foreign
corporations or other non-U.S. persons, subject to any

                                       17
<Page>

applicable treaty. However, distributions by the trust that are derived from
certain dividends of securities of a foreign corporation may not be subject to
U.S. income taxation and withholding in the case of units held by non-resident
alien individuals, foreign corporations or other non-U.S. persons.

     Some distributions by the trust may be subject to foreign withholding
taxes. Any dividends withheld will nevertheless be treated as income to you.
However, because you are deemed to have paid directly your share of foreign
taxes that have been paid or accrued by the trust, you may be entitled to a
foreign tax credit or deduction for U.S. tax purposes with respect to such
taxes.

     In the opinion of Emmet, Marvin & Martin, LLP, Special Counsel to the trust
for New York tax matters, under the existing income tax laws of the State of
New York, the trust is not an association taxable as a corporation and the
income of the trust will be treated as the income of the Unitholders thereof.

EXPERTS

     LEGAL MATTERS. Chapman and Cutler LLP, 111 West Monroe Street, Chicago,
Illinois 60603, acts as counsel for the trust and has passed upon the legality
of the units.

     INDEPENDENT AUDITORS. The statement of financial condition, including the
Trust Portfolio, appearing herein, has been audited by Grant Thornton LLP,
independent auditors, as set forth in their report thereon appearing elsewhere
herein, and is included in reliance on such report given on the authority of
such firm as experts in accounting and auditing.

PERFORMANCE INFORMATION

     Information contained 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 charges 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 charge 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.
