     Re:       CLAYMORE SECURITIES DEFINED PORTFOLIOS, SERIES 154

Gentlemen:

     We have acted as counsel to Claymore Securities Defined Portfolios, Series
154 (the "FUND"), in connection with the issuance of Units of fractional
undivided interest in the trust(s) of the Fund (the "TRUST(S)"), under a
Reference Trust Agreement dated July 25, 2003 (the "INDENTURE") between Claymore
Securities, Inc., as Sponsor, Depositor and Evaluator, and The Bank of New York
as Trustee.

     In this connection, we have examined the Registration Statement, the form
of Prospectus proposed to be filed with the Securities and Exchange Commission,
the Indenture and such other instruments and documents as we have deemed
pertinent. The opinions expressed herein assume that the Trust will be
administered, and investments by the Trust from proceeds of subsequent deposits,
if any, will be made in accordance with the terms of the Indenture. For purposes
of the following opinion and discussion, it is assumed that the Trust will hold
interests in qualified regulated investment companies ("RICs") under the
Internal Revenue Code of 1986 (the "CODE") (the "SECURITIES"). For purposes of
the following discussion and opinion, it is assumed that the Securities
constitute shares in funds qualifying as regulated investment companies for
federal income tax purposes.

     We have not independently examined the assets to be deposited in and held
by the Trust.

<Page>

     Based upon the foregoing and upon an investigation of such matters of law
as we consider to be applicable, we are of the opinion that, under existing
United States Federal income tax law:

     (i)    The Trust is not an association taxable as a corporation for Federal
income tax purposes, but will be governed by the provisions of subchapter J
(relating to trusts) of chapter 1, of the Internal Revenue Code of 1986 (the
"CODE").

     (ii)   Each Unitholder will be treated as the owner of a pro rata portion
of each of the assets of a Trust under the Code in the proportion that the
number of Units held by a Unitholder bears to the total number of Units
outstanding. Under subpart E, subchapter J of Chapter 1 of the Code, income of
the Trust will be treated as income of each Unitholder in the proportion
described above; and an item of Trust income will have the same character in the
hands of a Unitholder as it would have if the Unitholder directly owned the
assets of the Trust. Each Unitholder will be considered to have received his or
her pro rata share of income derived from each Trust asset when such income
would be considered to be received by the Unitholder if the Unitholder directly
owned the assets of the Trust.

     (iii)  The price a Unitholder pays for his or her Units, generally
including sales charges, is allocated among his or her pro rata portion of each
Security held by a Trust (in proportion to the fair market values thereof on the
valuation date closest to the date the Unitholder purchases his or her Units) in
order to determine his or her tax basis for his or her pro rata portion of each
Security held by a Trust. For Federal income tax purposes, a Unitholder's pro
rata portion of distributions received by the Trust from the Securities, other
than distributions which are properly designated as capital gains dividends or
exempt-interest dividends, are generally taxable as ordinary income to the
extent of the RIC's current and accumulated "earnings and profits." A
Unitholder's pro rata portion of dividends which exceeds such current and
accumulated earnings and profits will first reduce a Unitholder's tax basis in
such Security, and to the extent that such dividends exceed a Unitholder's tax
basis in such Security, shall be treated as gain from the sale or exchange of
property. However, it is important to note that pursuant to the recently enacted
"Jobs and Growth Tax Relief Reconciliation Act of 2003" (the "TAX ACT"), certain
ordinary income dividends received by the Trust (and distributed to the
Unitholders) from a regulated investment company may qualify to be taxed at the
same new rates that apply to net capital gain, provided certain holding period
requirements are satisfied and provided the dividends are attributable to
qualifying dividends received by the RIC itself. These special rules relating to
the taxation of ordinary income dividends from regulated investment companies
generally apply to taxable years beginning after December 31, 2002 and beginning
before January 1, 2009. Regulated investment companies will provide notice to
their shareholders of the amount of any distribution which may be taken into
account as a dividend which is eligible for the new capital gains tax rates.
Certain distributions on the Securities may qualify as "capital gain dividends,"
taxable to shareholders (and, accordingly, to the Unitholders as owners of a pro
rata portion of

<Page>

the Securities) as long-term capital gain, regardless of how long a shareholder
has owned such shares. Distributions of income and capital gains declared on
Securities in October, November, or December will be deemed to have been paid to
the shareholders (and, accordingly, to the Unitholders as owners of a pro rata
portion of the Securities) on December 31 of the year they are declared, even
when paid by the RIC during the following January.

     (iv)   Gain or loss will be recognized to a Unitholder (subject to various
nonrecognition provisions under the Code) upon redemption or sale of his or her
Units, except to the extent an in kind distribution of Securities is received by
such Unitholder from a Trust as discussed below. Such gain or loss is measured
by comparing the proceeds of such redemption or sale with the adjusted basis of
his or her Units. Before adjustment, such basis would normally be cost if the
Unitholder had acquired his or her Units by purchase. Such basis will be
reduced, but not below zero, by the Unitholder's pro rata portion of certain
types of dividends. However, any loss realized by a Unitholder with respect to
the disposition of his or her pro rata portion of Securities, to the extent such
Unitholder has owned his or her Units for less than six months or a Trust has
held the Securities for less than six months, will be treated as long-term
capital loss to the extent of the Unitholder's pro rata portion of any capital
gain dividends received (or deemed to have been received) with respect to each
Security.

     (v)    If the Trustee disposes of a Trust asset, (whether by sale,
exchange, liquidation, redemption, payment on maturity or otherwise), gain or
loss will be recognized to the Unitholder (subject to various nonregcognition
provisions under the Code) and the amount thereof will be measured by comparing
the Unitholder's aliquot share of the total proceeds from the transaction with
the basis for his or her fractional interest in the asset disposed of. Such
basis is ascertained by apportioning the tax basis for his or her Units (as of
the date on which the Units were acquired) ratably, according to their values as
of the valuation date nearest the date on which he or she purchased such Units.
A Unitholder's basis in his Units and of his fractional interest in each Trust
asset must be reduced, but not below zero, by the Unitholder's pro rata portion
of certain types of dividends.

     If more than 50% of the value of the total assets of the RIC consist of
stock or securities in foreign corporations, the RIC may elect to pass through
to its shareholders the foreign income and similar taxes paid by the RIC in
order to enable its shareholders to take a credit (or deduction) for foreign
income taxes paid by the RIC. If this election is made, Unitholders of a Trust,
because they are deemed to own a pro rata portion of the Securities held by such
Trust, as described above, must include in their gross income, for federal
income tax purposes, both their portion of dividends received by such Trust from
the RIC and also their portion of the amount which the RIC deems to be their
portion of foreign income taxes paid with respect to, or withheld from,
dividends, interest, or other income of the RIC from its foreign investments.
Unitholders may then subtract from their federal income tax the amount of such
taxes withheld, or else treat such foreign taxes as deductions from gross
income; however as in the case of investors

<Page>

receiving income directly from foreign sources, the above described tax credit
or deduction is subject to certain limitations.

     (vi)   Under the Indenture, under certain circumstances, a Unitholder
tendering Units for redemption may request an in kind distribution of Securities
upon the redemption of Units or upon the termination of a Trust. As previously
discussed, prior to the redemption of Units or the termination of a Trust, a
Unitholder is considered as owning a pro rata portion of each of a Trust's
assets. The receipt of an in kind distribution will result in a Unitholder
receiving whole Securities and possibly cash. The potential Federal income tax
consequences which may occur under an in kind distribution will depend upon
whether or not a Unitholder receives cash in addition to Securities. A
Unitholder will not recognize gain or loss if a Unitholder only receives
Securities in exchange for his or her pro rata portion in the Securities held by
a Trust. However, if a Unitholder also receives cash in exchange for a Trust
asset or a fractional share of a Security held by a Trust, such Unitholder will
generally recognize gain or loss based upon the difference between the amount of
cash received by the Unitholder and his or her tax basis in such Trust asset or
fractional share of a Security held by a Trust. The total amount of taxable
gains (or losses) recognized upon such redemption will generally equal the sum
of the gain (or loss) recognized under the rules described above by the
redeeming Unitholder with respect to each Security owned by a Trust.

     Distributions from a Trust attributable to dividends received by a Trust
from the Securities will generally not be eligible for the dividends received
deduction for corporations.

     Section 67 of the Code provides that certain miscellaneous itemized
deductions, such as investment expenses, tax return preparation fees and
employee business expenses will be deductible by an individual only to the
extent they exceed 2% of such individual's adjusted gross income. Unitholders
may be required to treat some or all of the expenses of a Trust as miscellaneous
itemized deductions subject to this limitation. In addition, Unitholders will
not be able to deduct some of their interest expense for debt they incurred or
continued to purchase or carry Trust Units.

     A Unitholder will recognize taxable gain (or loss) when all or part of his
or her pro rata interest in a Trust asset is disposed of for an amount greater
(or less) than his or her tax basis therefor in a taxable transaction, subject
to various non recognition provisions of the Code.

     If a Unitholder disposes of a Unit, he or she is deemed thereby to have
disposed of his or her entire pro rata interest in all Trust assets including
his or her pro rata portion of all of a Trust's assets represented by the Unit.

     In addition it should be noted that capital gains can be recharacterized as
ordinary income in the case of certain financial transactions that are
"conversion transactions."

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

     A Unitholder who is a foreign investor (i.e., an investor other than a
United States citizen or resident or United States corporation, partnership,
estate or trust) may be subject to United States Federal income taxes, including
withholding taxes on distributions from the Trust relating to such investor's
share of dividend income paid on Securities. A Unitholder who is a foreign
investor will not be subject to United States Federal income taxes, including
withholding taxes on any gain from the sale or other disposition of his or her
pro rata interest in any Security held by a Trust or the sale of his or her
Units provided that all of the following conditions are met:

            (i)   the gain is not effectively connected with the conduct by the
     foreign investor of a trade or business within the United States;

            (ii)  the foreign investor (if an individual) is not present in the
     United States for 183 days or more during his or her taxable year; and

            (iii) the foreign investor provides all certification which may be
     required of his status.

     The scope of this opinion is expressly limited to the matters set forth
herein, and, except as expressly set forth above, we express no opinion with
respect to any other taxes, including foreign, state or local taxes, foreign
investors, corporations, broker-dealers or collateral tax consequences with
respect to the purchase, ownership and disposition of Units.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement (File No. 333-106475) relating to the Units referred to
above and to the use of our name and to the reference to our firm in said
Registration Statement and in the related Prospectus.
