 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 Portfolio, Series 585, is a unit investment
trust that consists of Claymore/Guggenheim Investment-Grade Corporate Trust,
Series 1 (the "trust"). Claymore Securities, Inc. ("Claymore" or the "sponsor")
serves as the sponsor of the trust.

     The trust is scheduled to terminate in approximately ___ years.

                              Investment Objective

     The trust seeks to provide a high level of current income and to preserve
capital by investing in a portfolio primarily consisting of investment-grade
corporate bonds.

                          Principal Investment Strategy

     The trust will invest in a portfolio of corporate bonds with stated
maturities ranging from ____ to ____. The sponsor will select bonds that it
believes have the best chance to meet the trust's investment objective over its
approximate __ year life.

     The portfolio of the trust consists of corporate debt obligations which may
include U.S. government bonds, corporate bonds, mortgage- and asset-backed
securities, loan participations and corporate instruments. All of the corporate
bonds held in the trust will be rated investment-grade quality, as of the
trust's initial date of deposit (the "Inception Date"), by at least one of the
following ratings agencies: Standard & Poor's, a division of The McGraw-Hill
Companies, Inc. ("Standard & Poor's"), Fitch, Inc. ("Fitch") or Moody's
Investors Service ("Moody's"). Such rating relates to the underlying bonds and
not the trust. Investment-grade bonds are bonds that are rated at least in the
category of BBB by Standard & Poor's or Fitch or Baa by Moody's. A rating in the
category of BBB or Baa is the lowest possible investment-grade rating. See
"Description of Bond Ratings" for details.

     Certain bonds in the trust may be covered by insurance policies obtained
from _________, guaranteeing payment of principal and interest on the bonds when
due. As a result of such insurance, the insured bonds have received ratings that
may reflect the creditworthiness of the bond issuer. Please note that the
insurance relates only to the insured bonds in the trust and not to the units or
the market value of the bonds or of the units.

     The trust intends to pay interest distributions each month and expects to
[prorate the interest distributed on an annual basis; see "Distributions."]
Furthermore, investors may receive principal distributions from bonds being
called or sold prior to their maturity.

     The sponsor has selected Guggenheim Partners Asset Management, Inc.
("GPAM"), an affiliate of Guggenheim Partners, LLC to serve as the trust's
portfolio consultant. The portfolio consultant is responsible for assisting the
sponsor with the selection of the trust's portfolio.

                                 Bond Selection

     The sponsor considered the following factors, among others, in selecting
the bonds:

     o   The bonds must be rated as investment-grade or above by at least one of
         the rating agencies (BBB- or above by Standard & Poor's or Baa3 or
         above by Moody's);

     o   The price of the bonds relative to other bonds with comparable
         characteristics;

     o   The diversification of bonds with respect to the issuer with no one
         issuer comprising more than 20% of the final portfolio;

     o   Attractiveness of the interest payments relative to bonds with similar
         characteristics;

     o   The potential for early return of principal or any event risk which
         could have a negative impact on the price of the bonds; and

     o   No bonds issued by companies in the financial sector.

                               Guggenheim Partners
                          Asset Management, Inc. (GPAM)

     Guggenheim Partners, LLC is a global diversified financial services firm
whose primary business lines include asset management, investment advisory,
fixed income brokerage, institutional finance and merchant banking. Through its
affiliates, including Guggenheim Partners Asset Management, Inc., the firm
manages more than $30 billion in fixed-income and equity strategies. GPAM's team
is based in New York, Chicago and Los Angeles.

                                  Future Trusts

     The sponsor intends to create future trusts that follow the same investment
strategy. One such trust is expected to be available approximately _____ months
after the trust's Inception Date and upon the trust's termination. 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.

     of the items provided herein may vary.



                                 Principal Risks

     As with all investments, you may lose some or all of your investment in the
trust. Investors can lose money by investing in the trust. The value of the
units and the bonds held in the portfolio can each decline in value. The trust
also might not perform as well as you expect. This can happen for reasons such
as these:

     o   The sponsor does not actively manage the portfolio. Because the
         portfolio is fixed and not managed, in general, the sponsor only sells
         bonds at the trust's termination or in order to meet redemptions or to
         pay expenses. As a result, the price at which a bond is sold may not be
         the highest price the trust could have received during the life of the
         trust. Units of the trust are not deposits of any bank and are not
         insured or guaranteed by the Federal Deposit Insurance Corporation or
         any other government agency.

     o   No assurance can be given that the trust's investment objective will be
         achieved. This objective is subject to the continuing ability of the
         respective issuers of the bonds to meet their obligations.

     o   Due to the current state of the economy, the value of the bonds held by
         the trust may be subject to steep declines or increased volatility due
         to changes in performance or perception of the issuers. In the last
         year, economic activity has declined across all sectors of the economy,
         and the United States is experiencing increased unemployment. The
         current economic crisis has affected the global economy with European
         and Asian markets also suffering historic losses. Extraordinary steps
         have been taken by the governments of several leading economic
         countries to combat the economic crisis; however, the impact of these
         measures is not yet known and cannot be predicted.

     o   An issuer or an insurer of the bonds may be unwilling or unable to make
         principal payments and/or to declare distributions in the future, may
         call a security before its stated maturity, or may reduce the level of
         distributions declared. This may result in a reduction in the value of
         your units.

     o   The financial condition of an issuer or an insurer of the bonds may
         worsen or its credit ratings may drop, resulting in a reduction in the
         value of your units. This may occur at any point in time, including
         during the primary offering period.

     o   Corporate bonds are fixed rate debt obligations that generally decline
         in value with increases in interest rates, an issuer's or an insurer's
         worsening financial condition, a drop in bond ratings or when there is
         a decrease in federal income tax rates. Typically, bonds with longer
         periods before maturity are more sensitive to interest rate changes.

     o   Certain corporate bonds may be rated as investment-grade by only one
         rating agency. As a result, such split-rated securities may have more
         speculative characteristics and are subject to a greater risk of
         default than securities rated as investment-grade by any two of
         Standard & Poor's, Fitch or Moody's.

     o   If a decrease in net asset value occurs and units of the trust are
         tendered for redemption, the trust may be forced to liquidate some of
         its bonds which may be at a loss. If such redemptions are substantial
         enough, provisions of the trust's indenture could cause a complete and
         unexpected liquidation of the trust before its scheduled maturity,
         resulting in unanticipated losses for investors.

     o   Certain of the bonds included in the trust may be original issue
         discount bonds or "zero coupon" bonds, as noted in "Trust Portfolio."
         These bonds may be subject to greater price fluctuations with changing
         interest rates and contain additional risks.

     o   Inflation may lead to a decrease in the value of assets or income from
         investments.

     See "Investment Risks" for additional information.

                                      Taxes

     Interest on the bonds in the trust is subject to federal income taxes for
U.S. investors. You may receive principal payments if bonds are sold or called,
or mature. You will be subject to tax on any gain realized by the trust on the
disposition of bonds.

     For non-resident aliens, certain income from the trust will be exempt from
withholding for U.S federal income tax, provided certain conditions are met.
Consult your tax advisor with respect to the conditions that must be met in
order to be exempt for U.S. tax purposes.

     See "Tax Status" for further tax information.

                                  Distributions

     Holders of units will receive interest payments from the trust each month.
The trust prorates the interest distributed on an annual basis. Annual interest
distributions are expected to vary from year to year.

     Each unit of the trust at the Inception Date represents the fractional
undivided interest in the principal amount of underlying bonds set forth in the
"Trust Portfolio" and net income of the trust.

                                Market for Units

     A unit holder may dispose of its units by redemption through The Bank of
New York Mellon, which serves as the trustee of the trust (the "trustee"), or
sale of such units to the sponsor. The price received from the trustee or the
sponsor, respectively, by the unitholder for units being redeemed or sold is
based upon the aggregate bid price of the underlying bonds. Units can be sold at
any time to the sponsor or the trustee without fee or penalty.

     Until six months after the Inception Date or the end of the initial
offering period, 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 includes estimated organization costs. After such period, the amount paid
will not include such estimated organization costs.

                                Who Should Invest

     You should consider this investment if:

     o    You want to own a defined portfolio of investment-grade corporate
          bonds;

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

     o    You are seeking capital preservation.

     You should not consider this investment if:

     o    You are uncomfortable with the risks associated with a defined
          portfolio of investment-grade corporate bonds;

     o    You are uncomfortable with the risks of an unmanaged investment in
          securities; or

     o    You are seeking capital appreciation.

                                Fees and Expenses

     The amounts below are estimates of the direct and indirect expenses that
you may incur for primary market purchases based on a $1,000 unit price. Actual

                          ======          ======

(1)  The deferred sales fee is a fixed dollar amount equaling 39.50 per unit.
     Because of this the maximum sales fee, as a percentage of the Public
     Offering Price, will vary with changes in the Public Offering Price.
     Assuming a Public Offering Price of $1,000 per unit, the maximum sales fee
     will be 3.95% of the Public Offering Price per unit. If the price you pay
     for your units exceeds $1,000 per unit, the maximum sales fee will be less
     than 3.95% of the Public Offering Price. If the price you pay for your
     units is less than $1,000 per unit, the maximum sales fee will not exceed
     3.95% of the Public Offering Price.

(2)  The deferred sales fee will be deducted in three monthly installments
     commencing ________ 2009 and ending ________ 2009 ($_____ on the last
     business day of each month). If units are redeemed prior to the deferred
     sales charge period, the entire deferred sales fee will be collected. If
     you purchase units in the secondary market, your maximum sales fee will be
     3.95% of the Public Offering Price and may consist of an initial sales fee
     and the amount of any remaining deferred sales charge payments. The initial
     sales fee, which you will pay at the time of purchase, is equal to the
     difference between 3.95% of the Public Offering Price and the maximum
     remaining deferred sales fee. If you purchase units after the last deferred
     sales charge payment has been assessed, your maximum sales fee will consist
     of a one-time sales charge of 3.95% of the Public Offering Price per unit.

(3)  Organization costs include the portfolio consulting fee paid to GPAM for
     its assistance with the trust's portfolio.

(4)  Based on a unit with a $1,000 per unit Public Offering Price as of the
     Inception Date.

(5)  The trustee's fees and the sponsor's evaluation fee are based on the
     principal amount of the bonds in the trust on a monthly basis. Because such
     fees are based on the principal amount of the bonds in the trust, rather
     than the trust's net asset value, the fees will represent a greater
     percentage of the trust's net asset value if the bonds in the trust, on
     average, are valued below par. The sponsor's supervisory fee and the
     bookkeeping and administrative fee are based on the largest number of units
     in the trust at any time during that period. Because these fees are based
     on the largest number of units during a particular period, these fees will
     represent a greater percentage of the trust's net asset value as the number
     of units will decrease during that period. The sponsor serves as the
     evaluator.

(6)  During the first year the trustee may reduce its fee by a nominal amount
     that relates to the estimated interest to be earned prior to the expected
     delivery dates for the "when, as and if issued" or "delayed delivery"
     bonds. Should the interest exceed this amount, the trustee will reduce its
     fee up to its annual fee. After the first year, the trustee's fee will be
     the amount indicated above. Estimated net interest income will remain as
     shown.

(7)  Other estimated trust operating expenses include a licensing fee paid to
     GPAM for the use of intellectual property owned by GPAM, but do not include
     brokerage commissions and other transactional fees. The estimated trust
     operating expenses are based upon an estimated trust size of $____ million.
     Because certain of the operating expenses are fixed amounts, if the trust
     does not reach such estimated size or falls below the estimated size over
     its life, the actual amount of the operating expenses may, in some cases
     greatly exceed the amounts reflected.

                                     Example

     This example helps you compare the costs of this trust with other unit
trusts and mutual funds. In the example we assume that 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:

     1 year                             $
     3 years
     5 years
     10 years

     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 transaction fees paid by the trust or that broker-dealers may
charge for processing redemption requests.

(1)  Bonds of these issuers are all represented by contracts to purchase bonds.
     All contracts to purchase the bonds were entered into on ______ , 2009. All
     contracts are expected to be settled prior to or on ______ , 2009.

(2)  If applicable, this heading shows the year in which each issue of bonds is
     initially redeemable and the redemption price for that year unless
     otherwise indicated. Each such issue generally continues to be redeemable
     at declining prices thereafter, but not below par. "S.F." indicates a
     sinking fund has been or will be established with respect to an issue of
     bonds. In addition, certain bonds in the trust may be redeemed in whole or
     in part other than by operation of the stated optional call or sinking fund
     provisions under certain unusual or extraordinary circumstances specified
     in the instruments setting forth the terms and provisions of such bonds. A
     sinking fund is a reserve fund accumulated over a period of time for the
     retirement of debt. A sinking fund may be estimated based upon various
     factors or may be mandatory. Redemption pursuant to call provisions
     generally will, and redemption pursuant to sinking fund provisions may,
     occur at times when the redeemed bonds have an offering side valuation
     which represents a premium over par. To the extent that the bonds were
     deposited in the trust at a price higher than the price at which they are
     redeemed, this will represent a loss of capital when compared with the
     original Public Offering Price of the units. Conversely, to the extent that
     the bonds were acquired at a price lower than the redemption price, this
     will represent an increase in capital when compared with the original
     Public Offering Price of the units. Distributions generally will be reduced
     by the amount of the income which would otherwise have been paid with
     respect to redeemed bonds and there will be distributed to unitholders the
     principal amount and any premium received on such redemption. The estimated
     current return in this event may be affected by such redemptions. The tax
     effect on unitholders of such redemptions and resultant distributions is
     described in the section entitled "Tax Status."

(3)  The Standard & Poor's, Fitch's and Moody's corporate or municipal bond
     ratings are a current assessment of the creditworthiness of an obligor with
     respect to a specific obligation. This assessment of creditworthiness may
     take into consideration obligors such as guarantors, insurers or lessees.
     The bond rating is not a recommendation to purchase, sell or hold a bond,
     inasmuch as it does not comment as to market price or suitability for a
     particular investor. A brief description of the rating symbols and their
     meanings is set forth under "Description of Bond Ratings."

(4)  See Note (1) to "Statement of Financial Condition" regarding cost of bonds.
     The sponsor is responsible for initially acquiring the bonds that it
     selects for the trust and will deliver the bonds or arrange for the
     delivery of the bonds to the trust on the Inception Date at a price
     determined by the evaluator based upon prices provided by Standard & Poor's
     Securities Evaluations, an independent, industry-recognized corporate bond
     pricing service. The sponsor may acquire bonds from Guggenheim Capital
     Markets, LLC, an affiliate of Guggenheim Partners, LLC, who may accumulate
     such bonds on behalf of the sponsor. Standard & Poor's Securities
     Evaluations will provide the sponsor with an "offered side" quotation for
     the bonds, on the trust's Inception Date. The offering prices are greater
     than the current bid prices of the bonds which are the basis on which
     Redemption Price per unit is determined for purposes of redemption of units
     (see the first paragraphs under "Public Offering--Offering Price" and
     "Rights of Unitholders--Redemption--Computation of Redemption Price Per
     Unit"). Immediately prior to the deposit of the trust, the aggregate bid
     side valuation of the bonds in the trust was lower than the aggregate
     offering side valuation by ___%. Yield of bonds was computed on the basis
     of offering prices on the Inception Date.

(5)  Estimated annual interest income to the trust is $_____.

(6)  This bond has been purchased on a "when, as and if issued" or "delayed
     delivery" basis. Interest on these bonds begins accruing to the benefit of
     Unitholders on their respective dates of delivery. Delivery is expected to
     take place at various dates after the first settlement date.



================================================================================
 UNDERSTANDING YOUR INVESTMENT


                                    The Trust

     Organization. The trust is one of a series of similar but separate unit
investment trusts created under the laws of the State of New York by a Trust
Indenture and Agreement (the "Trust Agreement"). The Trust Agreement is dated as
of the Inception Date and is between Claymore Securities, Inc. as sponsor and as
evaluator ("evaluator") and The Bank of New York Mellon, as trustee. The
evaluator determines the value of the bonds held in the trust generally based
upon prices provided by a pricing service. On the Inception Date, the sponsor
deposited bonds, contracts and/or funds (represented by cash or a certified
check(s) and/or an irrevocable letter(s) of credit, issued by a major commercial
bank) for the purchase of certain interest-bearing obligations. After the
deposit of the bonds and the creation of the trust, the trustee delivered to the
sponsor the units (the "units") comprising the ownership of the trust. These
units are now being offered pursuant to this prospectus.

     Units. Each unit represents the fractional undivided interest in the
principal and net income of the trust. If any units of the trust are redeemed
after the Inception Date, the fractional undivided interest in the trust
represented by each unredeemed unit will increase. Units will remain outstanding
until redeemed or until the termination of the Trust Agreement for the related
trust.

                                 Public Offering

     Offering Price. The sponsor will serve as the trust's principal
underwriter. The price of the units of the trust as of the Inception Date was
determined by adding to the evaluator's determination of the aggregate offering
price of the bonds per unit, based upon prices provided by Standard & Poor's
Securities Evaluations, cash, other net assets in the portfolio and a pro rata
portion of estimated organization costs. As of the close of business on the
Inception Date, the sponsor may adjust the number of units of the trust so that
the Public Offering Price per Unit will equal approximately $1,000. During the
initial public offering period, sales of at least $______ or _____ units will be
entitled to a volume discount from the Public Offering Price as described below.
For purchases settling after the First Settlement Date, a proportionate share of
accrued and undistributed interest on the bonds at the date of delivery of the
units to the purchaser is also added to the Public Offering Price. However,
after the initial offering period or six months after the Inception Date, at the
discretion of the sponsor, the Public Offering Price of the units will not
include a pro rata portion of estimated organizational costs.

     During the initial offering period the aggregate offering price of the
bonds in the trust is determined by the evaluator. To determine such prices, the
evaluator utilizes prices received from Standard & Poor's Securities
Evaluations. Standard & Poor's Securities Evaluations determines such offering
prices (1) on the basis of current offering prices for the bonds, (2) if
offering prices are not available for any bonds, on the basis of current
offering prices for comparable bonds, (3) by making an appraisal of the value of
the bonds on the basis of offering prices in the market, or (4) by any
combination of the above. On or after the Inception Date, such determinations
are made each business day during the initial public offering period as of the
Evaluation Time set forth in "Essential Information," effective for all sales
made subsequent to the last preceding determination. For information relating to
the calculation of the Redemption Price, which is based upon the aggregate bid
price of the underlying bonds and which is be expected to be less than the
aggregate offering price, see "Rights of Unitholders--Redemption."

     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, the portfolio consulting fee, if applicable, and
the initial fees and expenses of the trustee. Your trust will sell securities to
reimburse us for these costs at the end of the initial offering period or after
six months, at the discretion of the sponsor. Organization costs will not exceed
the estimate set forth under "Fees and Expenses."

     Deferred Sales Fee. You pay a sales fee when you buy units. In the primary
market, the transactional sales fee for the trust typically has only a deferred
component and is a fixed-dollar amount of $39.50 per unit which, as a percentage
of the Public Offering Price, will vary over time. At a Public Offering Price of
$1,000 per unit, the deferred sales fee will be 3.95% of the Public Offering
Price per unit. If the price you pay for your units exceeds $1,000 per unit, the
deferred sales fee will be less than 3.95%. However, if the price you pay for
your units is less than $1,000 per unit, the deferred sales fee will not exceed
3.95%.

     Initial Sales Fee. Typically, the trust does not charge an initial sales
fee. However, if you purchase units of the trust in the secondary market, your
maximum sales fee will be 3.95% of the Public Offering Price per unit and may
consist of an initial sales fee and the amount of any remaining deferred sales
charge payments. The initial sales fee, which you will pay at the time of
purchase, is equal to the difference between 3.95% of the Public Offering Price
per unit and the remaining deferred sales fee. If you purchase units after the
last deferred sales charge payment has been assessed, your maximum sales fee
will consist of a one-time sales fee of 3.95% of the Public Offering Price 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 is a
fixed dollar amount per unit, your trust must charge the deferred sales fee per
unit regardless of any discounts. However, when you purchase units of your
trust, 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 the
sponsor will credit you the difference between your maximum sales fee and the
deferred sales fee at the time you buy units by providing you with additional
units.

     Large Purchases. During the primary offering period, you can reduce your
maximum sales fee by increasing the size of your investment.

     Investors who make large purchases during the primary offering period are
entitled to the following sales charge reductions:

                                     Sales Charge
                                   Reductions (as a
                                    % of the Public
     Purchase Amount                Offering Price)
     ---------------                --------------
     Less than $50,000                      %
     $50,000 - $99,999
     $100,000 - $249,999
     $250,000 - $499,999
     $500,000 - $999,999
     $1,000,000 or more

     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:

     o   purchases by your spouse or minor children, and

     o   purchases by your trust estate or fiduciary accounts.

     The discounts described above apply only during the primary 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.

     Advisory and Fee Accounts. We reduce your 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"). You pay only the portion
of the sales fee that the sponsor retains.

     This discount applies during the initial offering period [and in the
secondary market.] Your financial professional may purchase units with the Fee
Account CUSIP numbers to facilitate purchases under this discount, however, we
do not require that you buy units with these CUSIP numbers to qualify for the
discount. If you purchase units with these special CUSIP numbers, you should be
aware that you may receive cash distributions. We reserve the right to limit or
deny purchases of units with this discount by investors whose frequent trading
activity we determine to be detrimental to your trust. See "Expenses and Fees"
in this 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 with a purchase price reduction of $10 per
unit off of the maximum Public Offering Price, which will include 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 that trust is scheduled to terminate within 30 days of
redemption. 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." An exchange or rollover is generally treated
as a sale for federal income tax purposes. See "Tax Status" in this prospectus.
See "Expenses and Fees" in this prospectus.

     Employees. We do not charge the portion of the 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. This discount applies during the
initial offering period [and in the secondary market.] Only those broker-dealers
that allow their employees to participate in employee discount programs will be
eligible for this discount.

     Distribution of 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. For units sold in the primary offering period, the
distribution fee paid for a given transaction is as follows:

                                      Concession
                                    per Unit (as a
     Purchase Amount/              % of the Public
     Form of Purchase               Offering Price)
     ----------------               --------------
     Less than $50,000                      %
     $50,000 - $99,999
     $100,000 - $249,999
     $250,000 - $499,999
     $500,000 - $999,999
     $1,000,000 or more
     Rollover Purchases
     Fee Account and
       Employee Purchases

     We apply these amounts as a percent of the unit price per transaction at
the time of the transaction. Firms that are serving as underwriters are entitled
to additional compensation as described in "Underwriting Concessions" below. For
secondary market sales, the dealer concession will be ____% of the Public
Offering 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 payments will be
equal to 0.10% of the value of eligible Claymore unit trusts sold in the primary
market during a calendar quarter so long as the broker-dealers or other firms
sell at least $25 million of eligible Claymore unit trusts during the calendar
quarter. Eligible unit trusts include all Claymore unit trusts, other than
Claymore corporate bond portfolios, sold in the primary market. Redemptions of
units during the primary offering period will reduce the amount of units used to
calculate the volume concessions. In addition, dealer firms will not receive
volume concessions on the sale of units which are not subject to a transactional
sales fee. However, such sales will be included in determining whether a firm
has met the sales level breakpoints for volume concessions.]

     Underwriters other than the sponsor will sell units of the trust to other
broker-dealers and selling agents at the Public Offering Price per unit less a
concession or agency commission not in excess of the underwriter concession
allowed to the underwriters by the sponsor as described in "Underwriting
Concessions" below.

     Claymore reserves the right to modify or terminate the volume concession
program at any time. The sponsor may also pay to certain dealers an
administrative fee for information or service used in connection with the
distribution of trust units. Such amounts will be in addition to any concessions
received for the sale of units.

     In addition to the concessions described above, the sponsor may pay
additional compensation out of its own assets to broker-dealers that meet
certain sales targets and that have agreed to provide services relating to the
trust to their customers.

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

     The sponsor makes these payments for marketing, promotional or related
expenses, including, but not limited to, expenses of entertaining retail
customers and financial advisers, advertising, sponsorship of events or
seminars, obtaining information about the breakdown of unit sales among an
intermediary's representatives or offices, obtaining shelf space in
broker-dealer firms and similar activities designed to promote the sale of the
sponsor's products. The sponsor may make such payments to many intermediaries
that sell Claymore products. The sponsor may also make certain payments to, or
on behalf of, intermediaries to defray a portion of their costs incurred for the
purpose of facilitating unit sales, such as the costs of developing trading or
purchasing trading systems to process unit trades.

     Payments of such additional compensation, some of which may be
characterized as "revenue sharing," may create an incentive for financial
intermediaries and their agents to sell or recommend a Claymore product,
including your trust, over products offered by other sponsors or fund companies.
These arrangements will not change the price you pay for your units.

     We generally register units for sale in various states in the U.S. We do
not register units for sale in any foreign country. 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 [gain/lost] the amount set forth in each trust's "Trust
Portfolio" on the initial deposit of securities in each trust.

     Additional Units. After your trust is created, additional units of the
trust may be issued by depositing in the trust cash (or a bank letter of credit
in lieu of cash) with instructions to purchase bonds, contracts to purchase
bonds or additional bonds.

                            Underwriting Concessions

     The sponsor has entered into that certain Agreement Among Underwriters
pursuant to which it shall serve as the principal underwriter for the units of
the trust. The Agreement Among Underwriters provides that a public offering of
the units of the trust will be made at the Public Offering Price described in
the prospectus. Units may also be sold to or through dealers and other selling
agents during the initial offering period and in the secondary market at prices
representing a concession or agency commission as described in "Distribution of
Units."

     In addition to the concessions provided in "Distribution of Units," the
underwriters will receive from the sponsor the additional concession contained
in the following table:

                                      Additional
                                  Sales Concessions
                                      (as a % of
     Total Sales                      the Public
     (in thousands)                 Offering Price)
     ---------------                --------------
     $                                 $
     $      or more                    $

     In addition to any other benefits that the underwriters may realize from
the sale of the units of the trust, the Agreement Among Underwriters provides
that the sponsor will share with the other underwriters, on a pro rata basis,
[___%] of the net gain, if any, represented by the difference between the
sponsor's cost of the securities in connection with their acquisition (including
the cost of insurance obtained by the sponsor prior to the Inception Date for
individual securities, if any, and including the effects of portfolio hedging
gains and losses and portfolio hedging transaction costs, if any) and the
aggregate offering price thereof on the Inception Date (the "acquisition
profit") less a charge for acquiring the bonds in the portfolio and for the
sponsor maintaining a secondary market for the units. For purposes of
determining the acquisition profit, the sponsor will utilize the prices of the
bonds derived from Standard & Poor's Securities Evaluations. All units created
by the sponsor on the Inception Date will be eligible for the purpose of
determining the acquisition profit. Dealers who are underwriters will be
eligible for a portion of such acquisition profit, if any. [The underwriters are
not, however, eligible to receive the additional dealer concession in connection
with sales [$______ of more] of units of this trust as set forth in
"Distribution of Units."]

     Sponsor's and Dealers' Profits. As set forth under "Public
Offering--Offering Price," the sponsor and the dealers will receive gross
commissions equal to the specified percentages of the Public Offering Price of
the units of the trust.

     Also, any difference between the sponsor's cost to purchase the securities
and the price at which it sells them to the trust is considered profit or loss.
In offering units of the trust the sponsor and dealers will also realize profits
or sustain losses in the amount of any difference between the price at which
they acquire or buy units and the price at which they resell or redeem such
units and to the extent they earn sales charges on purchases.

                                Investment Risks

     Failure of Issuers or Insurers to Pay Interest and/or Principal. The
primary risk associated with an investment in bonds is that the issuer or
insurer of a bond may default on principal and/or interest payments when due on
the bond. Such a default would have the effect of lessening the income generated
by the trust and/or the value of the bonds and the trust's units. The bond
ratings assigned by major rating organizations are an indication of the issuer's
ability to make interest and principal payments when due on its bonds.
Subsequent to the Inception Date the rating assigned to a bond may decline.
Neither the sponsor nor the trustee shall be liable in any way for any default,
failure or defect in any bond or responsible for a decline in the rating of any
bond in the portfolio.

     Current economic conditions risk. In December 2008, the National Bureau of
Economic Research officially announced that the U.S. economy has been in a
recession since December 2007. This announcement came months after U.S. stock
markets entered bear market territory after suffering losses of 20% or more from
their highs of October 2007. This recession began with problems in the housing
and credit markets, many of which were caused by defaults on "subprime"
mortgages and mortgage-backed securities, eventually leading to the failures of
some large financial institutions. Economic activity has now declined across all
sectors of the economy, and the United States is experiencing increased
unemployment. The current economic crisis has affected the global economy with
European and Asian markets also suffering historic losses. Due to the current
state of the economy, the value of the bonds held by the trust may be subject to
steep declines or increased volatility due to changes in performance or
perception of the issuers. Extraordinary steps have been taken by the
governments of several leading economic countries to combat the economic crisis;
however, the impact of these measures is not yet known and cannot be predicted.

     Fixed-Rate Bonds. An investment in units of the trust should be made with
an understanding of the risks entailed in investments in fixed-rate bonds,
including the risk that the value of such bonds (and, therefore, of the units)
will decline with increases in interest rates. Inflation and the overall economy
are two of the major factors, among others, which contribute to fluctuations in
interest rates and the values of fixed-rate bonds. Bonds are also subject to the
risk that their values may decline if the issuer's financial condition worsens
or if perceptions of the issuer's financial condition change.

     Original Issue Discount Bonds and Zero Coupon Bonds. Certain of the bonds
in the trust may be original issue discount bonds and/or zero coupon bonds.
Original issue discount bonds are bonds originally issued at less than the
market interest rate. Zero coupon bonds are original issue discount bonds that
do not provide for the payment of any current interest. Zero coupon bonds are
subject to substantially greater price fluctuations during periods of changing
market interest rates than bonds of comparable quality that pay current income.
For federal income tax purposes, original issue discount on bonds must be
accrued over the term of the bonds. As a result, on sale or redemption of the
bonds, the difference between (i) the amount realized and (ii) the tax basis of
such bonds (properly adjusted for the accrual of original issue discount) will
generally be treated as taxable gain or loss. Your basis in original issue
discount bonds increases as original issue discount accrues. See "Tax Status"
herein.

     "When Issued" and "Delayed Delivery" Bonds. Certain bonds in the trust may
have been purchased by the sponsor on a "when issued" basis. Bonds purchased on
a "when issued" basis have not yet been issued by the issuer on the Inception
Date (although such issuer had committed to issue such bonds). In the case of
these and/or certain other bonds, the delivery of the bonds may be delayed
("delayed delivery") or may not occur. The effect of the trust containing
"delayed delivery" or "when issued" bonds is that unitholders who purchased
their units prior to the date such bonds are actually delivered to the trustee
may have to make a downward adjustment in the tax basis of their units. Such
downward adjustment may be necessary to account for interest accruing on such
"when issued" or "delayed delivery" bonds during the time between their purchase
of units and delivery of such bonds to the trust.

     Redemption or Sale Prior to Maturity. Certain of the bonds in the portfolio
of the trust may be called prior to their stated maturity date pursuant to
sinking fund or call provisions. A call provision is more likely to be exercised
when the offering price valuation of a bond is higher than its call price. Such
price valuation is likely to be higher in periods of declining interest rates.
Certain of the bonds may be sold or otherwise mature. In such cases, the
proceeds from such events will be distributed to unitholders. Thus, no assurance
can be given that the trust will retain for any length of time its present size
and composition.

     The trust may contain bonds that have "make whole" call options that
generally cause the bonds to be redeemable at any time at a designated price.
Such bonds are generally more likely to be subject to early redemption and may
result in the reduction of income received by the trust and the early
termination of the trust.

     To the extent that a bond was deposited in the trust at a price higher than
the price at which it is redeemable, or at a price higher than the price at
which it is sold, a sale or redemption will result in a loss in the value of
units. Distributions will generally be reduced by the amount of the income which
would otherwise have been paid with respect to sold or redeemed bonds. The
Estimated Current Return and Estimated Long-Term Return of the Units may be
adversely affected by such sales or redemptions.

     Market Discount. The portfolio of the trust may consist of some bonds whose
current market values were below principal value on the Inception Date. A
primary reason for the market value of such bonds being less than principal
value at maturity is that the interest rate of such bonds is at lower rates than
the current market interest rate for comparably rated bonds. Bonds selling at
market discounts tend to increase in market value as they approach maturity.

     Failure of a Contract to Purchase Bonds and Substitution of Bonds. In the
event of a failure to deliver any bond that has been purchased for the trust
under a contract ("failed bonds"), the sponsor is authorized to purchase other
bonds ("replacement bonds"). The trustee shall pay for replacement bonds out of
funds held in connection with the failed bonds and will accept delivery of such
bonds to make up the original principal of the trust. The replacement bonds must
be purchased within 20 days after delivery of the notice of the failed contract,
and the purchase price (exclusive of accrued interest) may not exceed the
principal attributable to the failed bonds. Whenever a replacement bond has been
acquired for the trust, the trustee shall, within five days thereafter, notify
all unitholders of the trust of the acquisition of the replacement bond and
shall, on the next distribution date which is more than 30 days thereafter, make
a pro rata distribution of the amount, if any, by which the cost to the trust of
the failed bond exceeded the cost of the replacement bond. In addition, a
replacement bond must (at the time of purchase):

     o    be a corporate debt obligation;

     o    have a fixed maturity or disposition date comparable to that of the
          failed bond it replaces;

     o    be purchased at a price that results in a yield to maturity and in a
          current return which is approximately equivalent to the yield to
          maturity and current return of the failed bond which it replaces; and

     o    be rated at least in the category of BBB or Baa by a major rating
          organization.

     If the right of limited substitution described above shall not be used to
acquire replacement bonds in the event of a failed contract, the sponsor will
refund the sales charge attributable to such failed bonds to all unitholders of
the trust, and distribute the principal attributable to such failed bonds on the
next monthly distribution date which is more than 30 days thereafter. In the
event a replacement bond is not acquired by the trust, the Estimated Net Annual
Interest Income per unit for the trust would be reduced and the Estimated
Current Return thereon might be lowered.

     Risk Inherent in an Investment in Different Types of Bonds. Corporate Debt
Obligations. An investment in units of the trust should be made with an
understanding of the risks that an investment in fixed rate, investment-grade
corporate debt obligations may entail, including the risk that the value of the
units will decline with increases in interest rates. Although in recent years
interest rates have been relatively stable, the high inflation of prior years,
together with the fiscal measures adopted in response to such inflation, have
resulted in wide fluctuations in interest rates and thus in the value of fixed
rate debt obligations generally. Generally, bonds with longer maturities will
fluctuate in value more than bonds with shorter maturities.

     A slowdown in the economy, or a development adversely affecting an issuer's
creditworthiness, may result in the issuer being unable to maintain earnings or
sell assets at the rate and at the prices, respectively, that are required to
produce sufficient cash flow to meet its interest and principal requirements and
accordingly such issuer may not be able to meet its obligations to make
principal and income payments. In addition, a slowdown in the economy or a
development adversely affecting an issuer's creditworthiness may also result in
the ratings of the bonds and the value of the underlying portfolio being
reduced. The trust may consist of corporate debt obligations that, in many
cases, do not have the benefit of covenants that would prevent the issuer from
engaging in capital restructurings or borrowing transactions in connection with
corporate acquisitions, leveraged buyouts or restructurings that could have the
effect of reducing the ability of the issuer to meet its obligations and might
also result in the ratings of the bonds and the value of the underlying
portfolio being reduced.

     Should the issuer of any corporate debt obligation default in the payment
of principal or interest, the trust may incur additional expenses seeking
payment on the defaulted bond. Because amounts recovered by the trust in payment
under the defaulted corporate debt obligation, if any, may not be reflected in
the value of the units until actually received by the trust, and depending upon
when a unitholder purchases or sells his or her units, it is possible that a
unitholder would bear a portion of the cost of recovery without receiving a
portion of any payment recovered.

     Liquidity. The bonds in the trust may not have been registered under the
Securities Act of 1933 and may not be exempt from the registration requirements
of the Securities Act of 1933. Many of the bonds may not be listed on a
securities exchange. Whether or not the bonds are listed, the principal trading
market for the bonds will generally be in the over-the-counter market. As a
result, the existence of a liquid trading market for the bonds may depend on
whether dealers will make a market in the bonds. There can be no assurance that
a market will be made for any of the bonds, that any market for the bonds will
be maintained or of the liquidity of the bonds in any markets made. The price at
which the bonds may be sold to meet redemptions and the value of a trust will be
adversely affected if trading markets for the bonds are limited or absent. The
trust may also contain non-exempt bonds in registered form which have been
purchased on a private placement basis. Sales of these bonds may not be
practicable outside the United States, but can generally be made to U.S.
institutions in the private placement market which may not be as liquid as the
general U.S. securities market. Since the private placement market is less
liquid, the prices received may be less than would have been received had the
markets been broader.

     Concentration Risk. The trust is considered to be "concentrated" in a
particular category when the bonds in that category constitute 25% or more of
the aggregate value of the portfolio. This makes the trust subject to more
market risk. If applicable, an investment in units of the trust should be made
with an understanding of the risks that these investments may entail, certain of
which are described below.

     Utility Issues. Certain of the bonds in the trust may be obligations of
utility issuers. In general, utilities are regulated monopolies engaged in the
business of supplying light, water, power, heat, transportation or means of
communication. Historically, the utilities industry has provided investors in
securities issued by companies in this industry with high levels of reliability,
stability and relative total return on their investments. However, an investment
in a trust which contains obligations of utility issuers should be made with an
understanding of the characteristics of such issuers and the risks which such an
investment may entail. General problems of such issuers would include the
difficulty in financing large construction programs in an inflationary period,
the limitations on operations and increased costs and delays attributable to
environmental considerations, the difficulty of the capital market in absorbing
utility debt, limitations on energy supplies, governmental rate caps,
deregulation, competition, variable operating costs, the difficulty in obtaining
fuel or energy at reasonable prices and the effect of energy conservation. All
of such issuers have been experiencing certain of these problems in varying
degrees. In addition, federal, state and municipal governmental authorities may
from time to time review existing, and impose additional, regulations governing
the licensing, construction and various items including the operation of nuclear
power plants, which may adversely affect the ability of the issuers of certain
of such bonds in certain trusts to make payments of principal and/or interest on
such bonds.

     Hospital and Health Care Facility Issues. Certain of the bonds in the trust
may be obligations of hospital and health care issuers. Payments on hospital and
health care facility bonds are dependent upon revenues of hospitals and other
health care facilities. These revenues come from private third-party payors and
government programs, including the Medicare and Medicaid programs, which have
generally undertaken cost containment measures to limit payments to health care
facilities. Hospitals and health care facilities are subject to various legal
claims by patients and others and are adversely affected by the increasing cost
of insurance.

     Telecommunications Issues. Certain of the bonds in the trust may be
obligations of telecommunications issuers. Payments on bonds of companies in the
telecommunications industry, including local, long-distance and cellular
service, the manufacture of telecommunications equipment, and other ancillary
services, are generally dependent upon the amount and growth of customer demand,
the level of rates permitted to be charged by regulatory authorities and the
ability to obtain periodic rate increases, the effects of inflation on the cost
of providing services, competition and the rate of technological innovation. The
industry is characterized by increasing competition in all sectors and extensive
regulation by the Federal Communications Commission and various state regulatory
authorities.

     Litigation and Legislation. To the best knowledge of the sponsor, there is
no litigation pending as of the Inception Date in respect of any bonds which
might reasonably be expected to have a material adverse effect upon the trust.
Nevertheless, lawsuits involving the bonds included in the trust or their
issuers may exist. At any time after the Inception Date, litigation may be
initiated on a variety of grounds, or legislation may be enacted, with respect
to bonds in the trust. The outcome of litigation of this nature can never be
entirely predicted. In addition, other factors may arise from time to time which
potentially may impair the ability of issuers to make payments due on the bonds.

                              The Secondary Market

     Although not obligated, the sponsor intends to maintain a market for the
units after the initial offering period and continuously offer to purchase units
at prices based on the redemption price per unit.

     The sponsor will pay all expenses to maintain a secondary market, except
the evaluator fees, trustee costs to transfer and record the ownership of units
and costs incurred in annually updating the trust's registration statement. We
may discontinue purchases of units at any time. If you wish to dispose of your
units, you should ask us for the current market prices before making a tender
for redemption to the trustee.

                     Estimated Current Return and Estimated
                         Long-Term Return to Unitholders

     The rate of return on each unit is measured in terms of both Estimated
Current Return and Estimated Long-Term Return. The Estimated Current Return per
unit and Estimated Long-Term Return per unit, each as of the Inception Date, is
set forth under "Summary of Essential Financial Information." Information
regarding the estimated distributions of principal and interest to unitholders
of the trust is available from the sponsor on request.

     Estimated Current Return is computed by dividing the Estimated Net Annual
Interest Income per unit by the Public Offering Price. Estimated Net Annual
Interest Income per unit will vary with changes in fees and expenses of the
trustee and the evaluator and with principal prepayment, redemption, maturity,
exchange or sale of bonds. The Public Offering Price per unit will vary with
changes in the institutional offering price of the bonds. Estimated Current
Return takes into account only the interest payable on the bonds and does not
involve a computation of yield to maturity or to an earlier redemption date nor
does it reflect any amortization of premium or discount from principal value on
the bond's purchase price. Moreover, because interest rates on bonds purchased
at a premium are generally higher than current interest rates on newly issued
bonds of a similar type with comparable ratings, the Estimated Current Return
per unit may be affected adversely if such bonds are redeemed prior to their
maturity. Therefore, there is no assurance that the Estimated Current Return as
set forth under "Summary of Essential Financial Information" will be realized in
the future.

     Estimated Long-Term Return is calculated using a formula that (i) takes
into consideration, and determines and factors in the relative weightings of,
the market values, yields (taking into account the amortization of premiums and
the accretion of discounts) and estimated retirements of all the bonds in the
trust and (ii) takes into account the expenses and sales charge associated with
each unit of the trust. The Estimated Long-Term Return assumes that each bond is
retired on its pricing life date (i.e., that date which produces the lowest
dollar price when yield price calculations are done for each optional call date
and the maturity date of a callable bond). If the bond is retired on any
optional call or maturity date other than the pricing life date, the yield to
the holder of that bond may be different than the initial quoted yield. Since
the market values and estimated retirements of the bonds, the expenses of the
trust and the Net Annual Interest Income and Public Offering Price per unit may
change, there is no assurance that the Estimated Long-Term Return as set forth
under "Summary of Essential Financial Information" will be realized in the
future. Contact the sponsor, as indicated on the back page of the Prospectus,
for information regarding the estimated principal and interest distribution
schedule of the trust.

                                   Tax Status

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

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

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

     Trust Status. The trust intends to qualify as a "regulated investment
company" under the federal tax laws. If the trust qualifies as a regulated
investment company and distributes its income as required by the tax law, the
trust generally will not pay federal income taxes.

     Distributions. After the end of each year, you will receive a tax statement
that separates the trust's distributions into three categories, exempt-interest
dividends, ordinary income distributions and capital gains dividends.
Exempt-interest dividends generally are excluded from your gross income for
federal income tax purposes. Some or all of the exempt-interest dividends,
however, may be taken into account in determining your alternative minimum tax
and may have other tax consequences (e.g., they may affect the amount of your
social security benefits that are taxed). Ordinary income distributions are
generally taxed at your ordinary tax rate. Generally, you will treat all capital
gains dividends as long-term capital gains regardless of how long you have owned
your units. To determine your actual tax liability for your capital gains
dividends, you must calculate your total net capital gain or loss for the tax
year after considering all of your other taxable transactions, as described
below. In addition, the trust may make distributions that represent a return of
capital for tax purposes and thus will generally not be taxable to you. The tax
status of your distributions from your trust is not affected by whether you
reinvest your distributions in additional units or receive them in cash. The
income from your trust that you must take into account for federal income tax
purposes is not reduced by amounts used to pay a deferred sales fee, if any. The
tax laws may require you to treat distributions made to you in January as if you
had received them on December 31 of the previous year.

     Dividends Received Deduction. A corporation that owns units generally will
not be entitled to the dividends received deduction with respect to dividends
received from the trust because the dividends received deduction is generally
not available for distributions from regulated investment companies.

     Sale or Redemption of Units. If you sell or redeem your units, you will
generally recognize a taxable gain or loss. To determine the amount of this gain
or loss, you must subtract your tax basis in your units from the amount you
receive in the transaction. Your tax basis in your units is generally equal to
the cost of your units, generally including sales charges. In some cases,
however, you may have to adjust your tax basis after you purchase your units.
Further, if you hold your units for six months or less, any loss incurred by you
related to the disposition of such a unit will be disallowed to the extent of
the exempt-interest dividends you received.

     Capital Gains and Losses. 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 beginning before January 1, 2011. For
later periods, if you are an individual, the maximum marginal federal tax rate
for net capital gain is generally 20% (10% for certain taxpayers in the 10% and
15% tax brackets). The 20% rate is reduced to 18% and the 10% rate is reduced to
8% for long-term capital gains from most property acquired after December 31,
2000 with a holding period of more than five years.

     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. However, if you receive a
capital gain dividend from your trust and sell your unit at a loss after holding
it for six months or less, the loss will be disallowed to the extent of the
exempt-interest dividends you received. To the extent, if any, it is not
disallowed, it will be recharacterized as long-term capital loss to the extent
of the capital gain dividend received. 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 treats certain capital gains as ordinary
income in special situations.

     Deductibility of Trust Expenses. Expenses incurred and deducted by your
trust will generally not be treated as income taxable to you. In some cases,
however, you may be required to treat your portion of these trust expenses as
income. In these cases you may be able to take a deduction for these expenses.
However, certain miscellaneous itemized deductions, such as investment expenses,
may be deducted by individuals only to the extent that all of these deductions
exceed 2% of the individual's adjusted gross income. Further, because the trust
pays exempt-interest dividends, which are treated as exempt interest for federal
income tax purposes, you will not be able to deduct some of your interest
expense for debt that you incur or continue to purchase or carry your units.

     Foreign Investors. If you are a foreign investor (i.e., an investor other
than a U.S. citizen or resident or a U.S. corporation, partnership, estate or
trust), you should be aware that, generally, subject to applicable tax treaties,
distributions from the trust will be characterized as dividends for federal
income tax purposes (other than dividends which the trust designates as capital
gain dividends) and (generally except for exempt-interest dividends) will be
subject to U.S. income taxes, including withholding taxes, subject to certain
exceptions described below. However, distributions received by a foreign
investor from the trust that are properly designated by the trust as capital
gain dividends may not be subject to U.S. federal income taxes, including
withholding taxes, provided that the trust makes certain elections and certain
other conditions are met. In the case of dividends with respect to taxable years
of the trust beginning prior to 2010, distributions from the trust that are
properly designated by the trust as an interest-related dividend attributable to
certain interest income received by the trust or as a short-term capital gain
dividend attributable to certain net short-term capital gain income received by
the trust may not be subject to U.S. federal income taxes, including withholding
taxes when received by certain foreign investors, provided that the trust makes
certain elections and certain other conditions are met.

                              Rights of Unitholders

     Ownership of Units. Ownership of units of the trust will not be evidenced
by certificates unless a unitholder, the unitholder's registered broker/dealer
or the clearing agent for such broker/dealer makes a written request to the
trustee. All evidence of ownership of uncertificated units will be recorded in
book-entry form either at Depository Trust Company ("DTC") through an investor's
broker's account or through registration of the units on the books of the
trustee. Units held through DTC will be registered in the nominee name Cede &
Co. Individual purchases of beneficial ownership interest in the trust will be
made in book-entry form through DTC or the trustee unless a certificate is
properly requested. Ownership and transfer of book-entry 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 book-entry 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 to the trustee and,
in the case of units evidenced by a certificate, by presenting and surrendering
such certificate to the trustee properly endorsed or accompanied by a written
instrument or instruments of transfer which should be sent by registered or
certified mail for the protection of the unitholder. Unitholders must sign such
written request, and such certificate or transfer instrument, exactly as their
names appear on the records of the trustee and on any certificate representing
the units to be transferred.

     Units may be purchased and certificates, if requested, will be issued 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. Any certificate issued will be numbered serially for
identification, issued in fully registered form and will be transferable only on
the books of the trustee. The trustee may require a unitholder to pay a
reasonable fee, to be determined in the sole discretion of the trustee, for each
certificate reissued or transferred and to pay any governmental charge that may
be imposed in connection with each such transfer or interchange. The trustee at
the present time does not intend to charge for the normal transfer or
interchange of certificates. Destroyed, stolen, mutilated or lost certificates
will be replaced upon delivery to the trustee of satisfactory indemnity
(generally amounting to 3% of the market value of the units), affidavit of loss,
evidence of ownership and payment of expenses incurred. Any unitholder who holds
a certificate may change to book entry ownership by submitting to the trustee
the certificate along with a written request that the units represented by such
certificate be held in book entry form.

     Distribution of Interest and Principal. Unitholders will receive interest
distributions on a monthly basis. Principal, including capital gains, and
interest will be distributed on the distribution date; provided, however, that,
other than for purposes of redemption, no distribution need be made from the
Principal Account if the balance therein is less than $___ per unit then
outstanding. If such condition exists, the trustee shall, on the next succeeding
distribution date, distribute the unitholder's pro rata share of the balance of
the Principal Account. Interest received by the trust will be distributed on
each applicable distribution date to unitholders of record of the trust as of
the preceding applicable Record Date who are entitled to such distributions at
that time. All distributions will be net of applicable expenses and funds
required for the redemption of units. See "Essential Information," "Rights of
Unitholders--Expenses and Fees" and "Selling Units--Redemption."

     The trustee will credit to the Interest Account for the trust all interest
received by the trust, including that part of the proceeds of any disposition of
bonds which represents accrued interest. Other receipts of the trust will be
credited to the Principal Account for the trust. The pro rata share of the
Interest Account of the trust and the pro rata share of cash in the Principal
Account (other than amounts representing failed contracts as previously
discussed) represented by each unit thereof will be computed by the trustee each
applicable Record Date. See "Essential Information." The trustee is not required
to pay interest on funds held in the Principal or Interest Accounts (but may
itself earn interest thereon and therefore benefits from the use of such funds).
Proceeds received from the disposition of any of the bonds subsequent to a
monthly Record Date and prior to the next succeeding monthly distribution date
will be held in the Principal Account for the trust and will not be distributed
until the second succeeding monthly distribution date. Because interest on the
bonds is not received by the trust at a constant rate throughout the year, any
particular interest distribution may be more or less than the amount credited to
the Interest Account of the trust as of the applicable Record Date. See
"Essential Information." Persons who purchase units between a Record Date and a
distribution date will receive their first distribution on the second
distribution date following their purchase of units under the applicable plan of
distribution.

     The difference between the estimated net interest accrued to the first
Record Date and to the related distribution date is an asset of the respective
unitholder and will be realized in subsequent distributions or upon the earlier
of the sale of such units or the maturity, redemption or sale of bonds in the
trust.

     Record dates for interest distributions will be the first day of the month.
All unitholders, however, who purchase units during the initial public offering
period and who hold them of record on the first Record Date will receive the
first distribution of interest. Details of estimated interest distributions, on
a per unit basis, appear in the "Summary of Essential Financial Information."
The amount of the regular distributions will generally change when bonds are
redeemed, mature or are sold or when fees and expenses increase or decrease.

     The trustee will, as of the fifteenth day of each month, deduct from the
Interest Account and, to the extent funds are not sufficient therein, from the
Principal Account, amounts necessary to pay the expenses of the trust as of the
first day of such month. See "Rights of Unitholders--Expenses and Charges." 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 the
trust. Amounts so withdrawn shall not be considered a part of the trust's assets
until such time as the trustee shall return all or any part of such amounts to
the appropriate account. In addition, the trustee may withdraw from the Interest
Account and the Principal Account such amounts as may be necessary to cover
redemption of units by the trustee. See "Rights of Unitholders--Redemption."
Funds which are available for future distributions, payments of expenses and
redemptions are in accounts which are non-interest bearing to the unitholders
and are available for use by the trustee pursuant to normal banking procedures.

     Because interest on bonds in the trust is payable at varying intervals,
usually in semiannual installments, the interest accruing to the trust will not
be equal to the amount of money received and available for distribution from the
Interest Account to unitholders. Therefore, on each applicable distribution
date, the amount of interest actually deposited in the Interest Account and
available for distribution may be slightly more or less than the interest
distribution made. In order to eliminate fluctuations in interest distributions
resulting from such variances during the first year of the trust, the trustee is
required by the Trust Agreement to advance such amounts as may be necessary to
provide interest distributions of approximately equal amounts. In addition, the
trustee has agreed to advance sufficient funds to the trust in order to reduce
the amount of time before distributions of interest to unitholders commence. The
trustee will be reimbursed, without interest, for any such advances from funds
available from the Interest Account of the trust. The trustee's fee takes into
account the costs attributable to the outlay of capital needed to make such
advances.

     In order to acquire certain of the bonds subject to contract, it may be
necessary to pay on the settlement dates for delivery of such bonds amounts
covering accrued interest on such bonds which exceed the amounts paid by
unitholders. The trustee has agreed to pay for any amounts necessary to cover
any such excess and will be reimbursed therefor (without interest) when funds
become available from interest payments on the particular bonds with respect to
which such payments may have been made.

     In addition, because of the varying interest payment dates of the bonds
comprising the trust portfolio, accrued interest at any point in time,
subsequent to the recovery of any advancements of interest made by the trustee,
will be greater than the amount of interest actually received by the trust and
distributed to unitholders.

     Therefore, there will usually remain an item of accrued interest that is
added to the value of the units. If a unitholder sells all or a portion of his
units, he will be entitled to receive his proportionate share of the accrued
interest from the purchaser of his units. Similarly, if a unitholder redeems all
or a portion of his units, the Redemption Price per unit which he is entitled to
receive from the trustee will also include accrued interest on the bonds. Thus,
the accrued interest attributable to a unit will not be entirely recovered until
the unitholder either redeems or sells such unit or until the trust is
terminated.

     Expenses and Fees. Investors will bear all or a portion of the costs
incurred in organizing the trust - including costs of preparing the registration
statement, the trust indenture and other closing documents, registering units
with the SEC and the states, the initial audit of the trust's portfolio, legal
expenses, payment of closing fees and any other out-of-pocket expenses. During
the initial public offering period only, a pro rata portion of such organization
costs will be charged upon the investor's purchase of units.

     The trustee's, sponsor's supervisory, bookkeeping and administrative and
sponsor's evaluation fees are set forth under "Fees and Expenses" in the
Investment Summary. The trustee's fee and the sponsor's evaluation fee, which is
earned for portfolio evaluation services, are based on the principal amount of
bonds on a monthly basis. Because such fees are based on the principal amount of
the bonds in the trust, rather than the trust's net asset value, the fees will
represent a greater percentage of the trust's net asset value if the bonds in
the trust, on average, are valued below par. The sponsor's supervisory fee,
which is earned for portfolio supervisory services, and the bookkeeping and
administrative fees are based on the largest number of units in the trust at any
time during such period. Because these fees are based on the largest number of
units during a particular period, these fees will represent a greater percentage
of the trust's net asset value as the number of units decreased during that
period. The sponsor's supervisory fee, bookkeeping and administrative and
sponsor's evaluation fee, which are not to exceed the maximum amount set forth
under "Fees and Expenses" for the trust, may exceed the actual costs of
providing portfolio supervisory, bookkeeping and administrative or evaluation
services for the trust, but at no time will the total amount the sponsor
receives for portfolio supervisory services, bookkeeping and administrative or
evaluation services rendered to all series of Claymore Securities Defined
Portfolios in any calendar year exceed the aggregate cost to them of supplying
such services in such year.

     The trustee will receive for its ordinary recurring services to the trust
an annual fee in the amount set forth under "Fees and Expenses" for the trust.
There is no minimum fee and, except as hereinafter set forth, no maximum fee.
For a discussion of certain benefits derived by the trustee from the trust's
funds, see "Rights of Unitholders--Distribution of Interest and Principal." For
a discussion of the services performed by the trustee pursuant to its
obligations under the Trust Agreement, reference is made to the material set
forth under "Rights of Unitholders."

     The trustee's fee, bookkeeping and administrative fees and the sponsor's
fees are payable monthly, each from the Interest Account to the extent funds are
available and then from the Principal Account. These fees may be increased
without approval of the unitholders by amounts not exceeding proportionate
increases in consumer prices for services as measured by the United States
Department of Labor's Consumer Price Index entitled "All Services Less Rent." If
the balances in the Principal and Interest Accounts are insufficient to provide
for amounts payable by the trust, or amounts payable to the trustee which are
secured by its prior lien on the trust, the trustee is permitted to sell bonds
to pay such amounts.

     The trust will pay a licensing fee to GPAM for the use of trademarks, trade
names or other intellectual property owned by GPAM. The [annual] licensing fees
received by GPAM are equal to ___% of the average net assets of the trust.

     Other Charges. The following additional charges are or may be incurred by a
trust: all expenses (including audit and counsel fees) of the trustee incurred
in connection with its activities under the Trust Agreement, including annual
audit expenses by independent public accountants selected by the sponsor, the
expenses and costs of any action undertaken by the trustee to protect the trust
and the rights and interests of the unitholders; fees of the trustee for any
extraordinary services performed under the Trust Agreement; indemnification of
the trustee for any loss or liability accruing to it without willful misconduct,
bad faith, or gross negligence on its part, arising out of or in connection with
its acceptance or administration of the trust; and all taxes and other
governmental charges imposed upon the bonds or any part of the trust (no such
taxes or charges are being levied or made or, to the knowledge of the sponsor,
contemplated). To the extent lawful, the trust shall bear the expenses
associated with updating the trust's registration statement and maintaining
registration or qualification of the units and/or the trust under federal or
state bonds 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. All
direct distribution expenses of the trusts (including the costs of maintaining
the secondary market for the trusts), such as printing and distributing
prospectuses, and preparing, printing and distributing any advertisements or
sales literature will be paid at no cost to the trust. Any payments received by
the sponsor reimbursing it for payments made to update the trust's registration
statement will not exceed the costs incurred by the sponsor. The above expenses,
including the trustee's fee, when paid by or owing to the trustee, are secured
by a lien on the trust. In addition, the trustee is empowered to sell bonds in
order to make funds available to pay all expenses.

     Reports and Records. The trustee shall furnish unitholders of a trust in
connection with each distribution a statement of the amount of interest, if any,
and the amount of other receipts, if any, which are being distributed, expressed
in each case as a dollar amount per unit. Within a reasonable time after the end
of each calendar year, the trustee will furnish to each person who at any time
during the calendar year was a unitholder of record, a statement providing the
following information: (1) as to the Interest Account: interest received
(including amounts representing interest received upon any disposition of bonds
and any earned original issue discount), deductions for payment of applicable
taxes and for fees and expenses of the trust, redemptions of units and the
balance remaining after such distributions and deductions, expressed both as a
total dollar amount and as a dollar amount representing the pro rata share of
each unit outstanding on the last business day of such calendar year; (2) as to
the Principal Account: the dates of disposition of any bonds and the net
proceeds received therefrom (excluding any portion representing interest),
deductions for payments of applicable taxes and for fees and expenses of the
trust, purchase of replacement bonds, redemptions of units, the amount of any
"when issued" interest treated as a return of capital and the balance remaining
after such distributions and deductions, expressed both as a total dollar amount
and as a dollar amount representing the pro rata share of each unit outstanding
on the last business day of such calendar year; (3) a list of the bonds held and
the number of units outstanding on the last business day of such calendar year;
(4) the Redemption Price per unit based upon the last computation thereof made
during such calendar year; and (5) amounts actually distributed during such
calendar year from the Interest Account and from the Principal Account,
separately stated, expressed both as total dollar amounts and as dollar amounts
representing the pro rata share of each unit outstanding.

     The trustee shall keep available for inspection by unitholders at all
reasonable times during usual business hours, books of record and account of its
transactions as trustee including records of the names and addresses of
unitholders of the trust, certificates issued or held, a current list of bonds
in the trust and a copy of the Trust Agreement.

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

     Redemption. Tender of Units. Units may be tendered to The Bank of New York
Mellon, the trustee, for redemption at its Unit Investment Trust Division
offices at 2 Hanson Place, 12th Fl., Brooklyn, New York 11217, on any day the
New York Stock Exchange is open. At the present time there are no specific taxes
related to the redemption of the units. No redemption fee will be charged by the
sponsor or the trustee. Units redeemed by the trustee will be canceled.

     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. 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.

     [To redeem your units which are evidenced by registered certificates, if
any, you must send the trustee any certificates for your units.] You must
properly endorse your certificates or sign a written transfer instrument with a
signature guarantee. The trustee cannot complete your redemption or send your
payment to you until it receives all of these documents in completed form.

     Unitholders must sign the request, and such certificate or transfer
instrument, exactly as their names appear on the records of the trustee and on
any certificate representing the units to be redeemed. If the amount of the
redemption is $500 or less and the proceeds are payable to the unitholder 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. A certificate should only be sent by registered or
certified mail for the protection of the unitholder. Since tender of the
certificate is required for redemption when one has been issued, units
represented by a certificate cannot be redeemed until the certificate
representing such units has been received by the purchasers.

     Within three business days following such tender, the unitholder will be
entitled to receive in cash an amount for each unit tendered equal to the
Redemption Price per unit computed as of the Evaluation Time set forth under
"Essential Information" as of the next subsequent Evaluation Time. See
"Redemption--Computation of Redemption Price per Unit." The "date of tender" is
deemed to be the date on which units are properly received by the trustee,
except that with regard to units received after the Evaluation Time on the New
York Stock Exchange, the date of tender is the next day on which such Exchange
is open for trading and such units will be deemed to have been tendered to the
trustee on such day for redemption at the Redemption Price computed on that day.

     Accrued interest paid on redemption shall be withdrawn from the Interest
Account, or, if the balance therein is insufficient, from the Principal Account.
All other amounts paid on redemption shall be withdrawn from the Principal
Account. The trustee is empowered to sell securities in order to make funds
available for redemption. Such sales, if required, could result in a sale of
bonds by the trustee at a loss. To the extent bonds are sold, the size and
diversity of the trust may be reduced.

     The trustee reserves the right to suspend the right of redemption and to
postpone the date of payment of the Redemption Price per Unit for any period
during which the New York Stock Exchange is closed, other than weekend and
holiday closings, or during which trading on that Exchange is restricted (as
determined by the SEC by rule or regulation) or during which an emergency exists
as a result of which disposal or evaluation of the underlying bonds is not
reasonably practicable, or for such other periods as the SEC has by order
permitted.

     You can generally request an in-kind distribution of the stocks underlying
your units if you own units worth at least $1,000,000 or you originally paid at
least that amount for your units. This option is generally available only for
securities traded and held in the United States and is not available within 30
business days of the trust's termination. We may modify or discontinue this
option at any time without notice. If you request an in-kind distribution of the
securities underlying units of your trust, you may incur any distribution or
service fees (Rule 12b-1 fees) applicable to those securities.

     Computation of Redemption Price per Unit. The Redemption Price per unit is
determined by the trustee on the basis of the bid prices of the bonds in the
trust, while the Public Offering Price of units during the initial offering
period is determined on the basis of the offering prices of the bonds, both as
of the Evaluation Time on the day any such determination is made. The bid prices
of the securities may be expected to be less than the offering prices. This
Redemption Price per unit is each unit's pro rata share, determined by the
trustee, of: (1) the aggregate value of the bonds in the trust (determined by
the evaluator, generally based upon prices provided by a pricing service as set
forth below), (2) cash on hand in the trust (other than cash covering contracts
to purchase bonds), and (3) accrued and unpaid interest on the bonds as of the
date of computation, less (a) amounts representing taxes or governmental charges
payable out of the trust, (b) the accrued expenses of a trust, (c) cash held for
distribution to unitholders of record as of a date prior to the evaluation, and
(d) unpaid organization costs. The evaluator, generally based upon prices
provided by a pricing service may determine the value of the bonds in the trust
(1) on the basis of current bid prices for the bonds, (2) if bid prices are not
available for any bonds, on the basis of current bid prices for comparable
bonds, (3) by appraisal, or (4) by any combination of the above.

     Until six months after the Inception Date or the end of the initial
offering period, 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 includes estimated organization costs. After such period, the amount paid
will not include such estimated organization costs.

     The difference between the bid and offer prices of bonds with
characteristics consistent with the objectives of the trust are expected to be
____% to ____% of the principal value of the bonds. This value can fluctuate
depending on liquidity and the balance of supply and demand for the individual
issues. Immediately prior to the deposit of the trust, the aggregate bid side
evaluation was lower than the aggregate offering side evaluation by the amount
set forth in the footnotes to the "Trust Portfolio." For this reason, among
others, the price at which units may be redeemed could be less than the price
paid by the unitholder.

     Purchase by the Sponsor of Units Tendered for Redemption. The Trust
Agreement requires that the trustee notify the sponsor of any tender of units
for redemption. So long as the sponsor maintains a bid in the secondary market,
the sponsor, prior to the close of business on the second succeeding business
day, will purchase any units tendered to the trustee for redemption at the price
so bid by making payment therefor to the unitholder in an amount not less than
the Redemption Price on the date of tender not later than the day on which the
units would otherwise have been redeemed by the trustee (see "Public
Offering--Offering Price"). Units held by the sponsor may be tendered to the
trustee for redemption as any other units.

     The offering price of any units resold by the sponsor will be the Public
Offering Price determined in the manner provided in this Prospectus (see "Public
Offering-Offering Price"). Any profit resulting from the resale of such units
will belong to the sponsor which likewise will bear any loss resulting from a
lower offering or redemption price subsequent to their acquisition of such units
(see "Public Offering-Other Compensation and Benefits to Broker-Dealers").

     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 may need to meet certain criteria. We may
discontinue this option at any time.

                               General Information

     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, have underwritten closed-end funds and have
distributed bonds, mutual funds, closed-end funds, exchange-traded funds,
structured products and unit trusts in the primary and secondary markets. We are
a registered broker-dealer and member of the Financial Industry Regulatory
Authority (FINRA). If we fail to or cannot perform our duties as sponsor or
become bankrupt, the trustee may replace us, continue to operate your trust
without a sponsor, or terminate the 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 may
from time to time maintain a position in certain securities held by the trust.

     Claymore and the 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 the trust.

     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 to
be 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 SEC, 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 foregoing information with regard to the sponsor relates to the sponsor
only and not to the trust. Such information is included in this prospectus only
for the purpose of informing investors as to the financial responsibility of the
sponsor and its ability to carry out its contractual obligations with respect to
the trust. More comprehensive financial information can be obtained upon request
from the sponsor.

     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 or for errors in judgment; nor will
they be responsible in any way for depreciation or loss incurred by reason of
the sale of any bonds, except in cases of their willful misconduct, bad faith,
gross negligence or reckless disregard for their obligations and duties.

     Responsibility. The trustee shall sell, for the purpose of redeeming units
tendered by any unitholder and for the payment of expenses for which funds are
not available, such of the bonds in a list furnished by the sponsor as the
trustee in its sole discretion may deem necessary.

     It is the responsibility of the sponsor to instruct the trustee to reject
any offer made by an issuer of any of the bonds to issue new obligations in
exchange and substitution for any bonds pursuant to a refunding or refinancing
plan, except that the sponsor may instruct the trustee to accept such an offer
or to take any other action with respect thereto as the sponsor may deem proper
if the issuer is in default with respect to such bonds or in the judgment of the
sponsor the issuer will probably default in respect to such bonds in the
foreseeable future.

     Any obligations so received in exchange or substitution will be held by the
trustee subject to the terms and conditions of the Trust Agreement to the same
extent as bonds originally deposited thereunder. Within five days after the
deposit of obligations in exchange or substitution for underlying bonds, the
trustee is required to give notice thereof to each unitholder, identifying the
obligations eliminated and the bonds substituted therefor. Except as stated in
the Trust Agreement or in this and the preceding paragraph and in the discussion
under "Investment Risks--Failure of a Contract to Purchase Bonds and
Substitution of Bonds" regarding the substitution of replacement bonds for
failed bonds, the acquisition by a trust of any bonds other than the bonds
initially deposited is prohibited.

     The sponsor may direct the trustee to dispose of bonds in certain limited
circumstances, including upon default in the payment of principal or interest,
institution of certain legal proceedings or the existence of certain other
impediments to the payment of bonds, default under other documents which may
adversely affect debt service, default in the payment of principal or interest
on other obligations of the same issuer, decline in projected income pledged for
debt service on revenue bonds, or decline in price or the occurrence of other
market factors, including advance refunding, so that in the opinion of the
sponsor the retention of such bonds in a trust would be detrimental to the
interest of the unitholders. The proceeds from any such sales will be credited
to the Principal Account for distribution to the unitholders.

     Resignation. If the sponsor resigns or becomes unable to perform its duties
under the Trust Agreement, and no express provision is made for action by the
trustee in such event, the trustee may appoint a successor sponsor, terminate
the Trust Agreement and liquidate the trusts or continue to act as Trustee.

     The Trustee. The Bank of New York Mellon 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, 2 Hanson Place, 12th Fl., Brooklyn, New York
11217. [The sponsor may remove and replace the trustee in some cases without
your consent.] The trustee may also resign by notifying Claymore and investors.

     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 the 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 or available for
inspection at all reasonable times during usual business hours by any
unitholder, together with a current list of the bonds held in the trust.
Pursuant to the Trust Agreement, the trustee may employ one or more agents for
the purpose of custody and safeguarding of bonds comprising the trust.

     Limitations on Liability. The trustee shall not be liable or responsible in
any way for depreciation or loss incurred by reason of the disposition of any
monies, bonds or certificates or in respect of any evaluation or for any action
taken in good faith reliance on prima facie properly executed documents except,
generally, in cases of its willful misconduct, lack of good faith or gross
negligence. In addition, the trustee shall not be personally liable for any
taxes or other governmental charges imposed upon or in respect of the trust
which the trustee may be required to pay under current or future law of the
United States or any other taxing authority having jurisdiction. See "Trust
Portfolio."

     Responsibility. For information relating to the responsibilities of the
trustee under the Trust Agreement, reference is made to the material set forth
under "Rights of Unitholders," "Sponsor--Responsibility" and
"Sponsor--Resignation."

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

     The trustee or successor trustee must mail a copy of the notice of
resignation to all unitholders then of record, not less than sixty days before
the date specified in such notice when such resignation is to take effect. The
sponsor upon receiving notice of such resignation is obligated to appoint a
successor trustee promptly. If, upon such resignation, no successor trustee 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 Evaluator. The sponsor will serve as the evaluator of the bonds in the
trust, and as such will appraise the bonds or cause the bonds to be appraised.
To appraise the bonds, the evaluator generally utilizes prices received from
Standard & Poor's Securities Evaluations.

     Limitations on Liability. The trustee and the sponsor may rely on any
evaluation furnished by the evaluator and shall have no responsibility for the
accuracy thereof. Determinations by the evaluator under the Trust Agreement
shall be made in good faith upon the basis of the best information available to
it; provided, however, that the evaluator shall be under no liability to the
trustee, the sponsor or unitholders for errors in judgment. However, this
provision shall not protect the evaluator in cases of its willful misfeasance,
bad faith, gross negligence or reckless disregard of its obligations and duties.

     Responsibility. The Trust Agreement requires the evaluator to evaluate the
bonds on the basis of their bid prices on each business day after the initial
offering period, when any unit is tendered for redemption and on any other day
such evaluation is desired by the trustee or is requested by the sponsor. For
information relating to the responsibility of the evaluator to evaluate the
bonds on the basis of their offering prices, see "Public Offering--Offering
Price."

     Resignation. The evaluator may resign or may be removed by the sponsor and
the trustee, and the sponsor and the trustee are to use their best efforts to
appoint a satisfactory successor. Such resignation or removal shall become
effective upon the 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.

     GPAM. Guggenheim Partners Asset Management, Inc. has been selected by the
sponsor to serve as the portfolio consultant for the trust. As portfolio
consultant, GPAM will assist the sponsor with the selection of the portfolio of
the trust. For its service as portfolio consultant, GPAM will be paid by the
trust a fee of ___% of the average net assets of the trust at the close of the
initial offering period. GPAM may also provide advice to the sponsor to help the
sponsor provide portfolio supervisory services to the trust. The sponsor may pay
some or all of its supervisory fee to GPAM.

     GPAM is not an affiliate of the sponsor. Neither the sponsor nor GPAM will
manage the trust. GPAM may use the list of securities in its independent
capacity as an investment adviser and distribute this information to various
individuals and entities. GPAM may recommend or effect transactions in the
securities included in the trust. This may have an adverse effect on the prices
of the securities included in the trust. This also may have an impact on the
price the trust pays for the securities and the price received upon unit
redemptions or trust termination. GPAM may act as agent or principal in
connection with the purchase and sale of securities, including the securities
included in the trust. GPAM's research department may receive compensation based
on commissions generated by research and/or sales of units.

                            Amendment and Termination
                             of the Trust Agreement

     The sponsor and the trustee have the power to amend the Trust Agreement
without the consent of any of the unitholders when such an amendment is (1) to
cure any ambiguity or to correct or supplement any provision of the Trust
Agreement which may be defective or inconsistent with any other provision
contained therein, (2) to change any provision required to be changed by the
SEC, or (3) to make such other provisions as shall not adversely affect the
interest of the unitholders. The sponsor and the trustee may amend the Trust
Agreement with the consent of unitholders representing 662 1/43% of the units
then outstanding, provided that no such amendment will reduce the interest in
the trust of any unitholder without the consent of such unitholder or reduce the
percentage of units required to consent to any such amendment without the
consent of all the unitholders. In no event shall the Trust Agreement be amended
to permit the deposit or acquisition of bonds either in addition to or in
substitution for any of the bonds initially deposited in a trust, except in
accordance with the provisions of each Trust Agreement. In the event of any
amendment, the trustee is obligated to notify promptly all unitholders of the
substance of such amendment. The Trust Agreement specifies other limitations on
amending the Trust Agreement.

     A trust shall terminate upon the maturity, redemption, sale or other
disposition, as the case may be, of the last of the bonds. The sponsor may
direct the trustee to terminate the trust if the value of the trust falls below
_____. The trustee shall notify the sponsor when the par value of the bonds in a
trust is less than [$2,000,000.] A trust may also be terminated (i) by the
consent of 662 1/43% of the units or (ii) by the trustee in certain
circumstances. In no event, however, may a trust continue beyond the Mandatory
Termination Date set forth herein. In the event of termination, written notice
thereof will be sent by the trustee to all unitholders. Within a reasonable
period after termination, the trustee will sell any remaining bonds, and, after
paying all expenses and charges incurred by the trust, will distribute to each
unitholder, upon surrender of his units (including certificates, if any), his
pro rata share of the balances remaining in the Interest and Principal Accounts
of the trust.

                           Description of Bond Ratings

     Standard & Poor's Rating. A Standard & Poor's issue credit rating is a
current opinion of the creditworthiness of an obligor with respect to a specific
financial obligation, a specific class of financial obligations, or a specific
financial program (including ratings on medium term note programs and commercial
paper programs). It takes into consideration the creditworthiness of guarantors,
insurers, or other forms of credit enhancement on the obligation and takes into
account the currency in which the obligation is denominated. The opinion
evaluates the obligor's capacity and willingness to meet its financial
commitments as they come due, and may assess terms, such as collateral security
and subordination, which could affect ultimate payment in the event of default.
The issue credit rating is not a recommendation to purchase, sell, or hold a
financial obligation, inasmuch as it does not comment as to market price or
suitability for a particular investor. Issue credit ratings are based on current
information furnished by the obligors or obtained by Standard & Poor's from
other sources it considers reliable. Standard & Poor's does not perform an audit
in connection with any credit rating and may, on occasion, rely on unaudited
financial information. Credit ratings may be changed, suspended, or withdrawn as
a result of changes in, or unavailability of, such information, or based on
other circumstances.

     Issue credit ratings are based, in varying degrees, on the following
considerations:

     o   Likelihood of payment--capacity and willingness of the obligor to meet
         its financial commitment on an obligation in accordance with the terms
         of the obligation;

     o   Nature of and provisions of the obligation; and

     o   Protection afforded by, and relative position of, the obligation in the
         event of bankruptcy, reorganization, or other arrangement under the
         laws of bankruptcy and other laws affecting creditors' rights.

     AAA -- An obligation rated `AAA' has the highest rating assigned by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is extremely strong.

     AA -- An obligation rated `AA' differs from the highest rated obligations
only in small degree. The obligor's capacity to meet its financial commitment on
the obligation is very strong.

     A -- An obligation rated `A' is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

     BBB -- An obligation rated `BBB' exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

     Plus (+) or minus (-) -- The ratings from `AA' to `CCC' may be modified by
the addition of a plus or minus sign to show relative standing within the major
rating categories.

     N.R. -- This indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular obligation as a matter of policy.

     *Moody's Investors Service Rating. A summary of the meaning of the
applicable rating symbols as published by Moody's follows:

     Aaa-Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

     Aaa -- Obligations rated Aaa are judged to be of the highest quality, with
minimal credit risk.

     Aa -- Obligations rated Aa are judged to be of high quality and are subject
to very low credit risk.

     A -- Obligations rated A are considered upper-medium grade and are subject
to low credit risk.

     Baa -- Obligations rated Baa are subject to moderate credit risk. They are
considered medium-grade and as such may possess certain speculative
characteristics.

     Moody's applies numerical modifiers 1, 2 and 3 in each rating
classification from "Aa" through "Caa." The modifier 1 indicates that the issuer
or obligation ranks in the higher end of its generic rating category; the
modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking
ranks in the lower end of its generic rating category.

     **Fitch Ratings. A brief description of the applicable Fitch Ratings'
symbols and their meanings is as follows:

     AAA -- Highest credit quality. `AAA' ratings denote the lowest expectation
of default risk. They are assigned only in cases of exceptionally strong
capacity for payment of financial commitments. This capacity is highly unlikely
to be adversely affected by foreseeable events.

     AA -- Very high credit quality. `AA' ratings denote expectations of very
low default risk. They indicate very strong capacity for payment of financial
commitments. This capacity is not significantly vulnerable to foreseeable
events.

     A -- High credit quality. `A' ratings denote expectations of low default
risk. The capacity for payment of financial commitments is considered strong.
This capacity may, nevertheless, be more vulnerable to adverse business or
economic conditions than is the case for higher ratings.

     BBB -- Good credit quality. `BBB' ratings indicate that expectations of
default risk are currently low. The capacity for payment of financial
commitments is considered adequate but adverse business or economic conditions
are more likely to impair this capacity. This is the lowest investment-grade
category.

     The modifiers "+" or "-" may be appended to a rating to denote relative
status within major rating categories. Such suffixes are not added to the `AAA'
Long-term rating category or to categories below `B'.




             Report of Independent Registered Public Accounting Firm

Unitholders

Claymore Securities Defined Portfolios, Series 585

     We have audited the accompanying statement of financial condition,
including the trust portfolio set forth on pages 10 and 11 of this prospectus,
of Claymore Securities Defined Portfolios, Series 585, as of ______ , 2009, the
Inception Date. 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 the auditing standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the statement of financial condition is free of material misstatement.
The trust is not required to have, nor were we engaged to perform an audit of
its internal control over financial reporting. Our audit included consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the statement of financial condition, assessing the accounting
principles used and significant estimates made by the sponsor, as well as
evaluating the overall statement of financial condition presentation. Our
procedures included confirmation with The Bank of New York Mellon, trustee, [of
cash or an irrevocable letter of credit deposited for the purchase of
securities] as shown in the statement of financial condition as of ______ ,
2009. 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 585, as of ______ , 2009, in conformity
with accounting principles generally accepted in the United States of America.

                                                              Grant Thornton LLP

(1)  Aggregate cost of the securities is based on the closing sale price
     evaluations as determined by the Standard &Poor's Securities Evaluations.

(2)  Cash and/or a letter of credit has been deposited with The Bank of New York
     Mellon, trustee, covering the funds (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 $____ per unit of the trust. A
     distribution will be made as of the close of the initial offering period or
     six months after the Inception Date (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 the trust.

(4)  The total sales fee consists of a deferred sales fee. On the Inception
     Date, the sales fee is 3.95% of the Public Offering Price (equivalent to
     ____% of the net amount invested).

     fee assuming no reduction of transactional sales fees for quantity
     purchases.
