            Re:   Advent Claymore Convertible Securities and Income
                  Fund Registration Statement on Form N-2
                  ---------------------------------------

Ladies and Gentlemen:

          We have acted as special counsel to Advent Claymore Convertible
Securities and Income Fund, a statutory trust created under the Delaware
Statutory Trust Act (the "Trust"), in connection with the public offering by the
Trust of up to 2,150 shares of the Trust's Series M7 Auction Market Preferred
Shares of Beneficial Interest, liquidation preference $25,000 per share; 2,150
shares of the Trust's Series T28 Auction Market Preferred Shares of Beneficial
Interest, liquidation preference $25,000 per share; 2,150 shares of the Trust's
Series W7 Auction Market Preferred Shares of Beneficial Interest, liquidation
preference $25,000 per share; and 2,150 shares of the Trust's Series TH28
Auction Market Preferred Shares of Beneficial Interest, liquidation preference
$25,000 per share (collectively, the "AMPS").

          This opinion is being furnished in accordance with the requirements of
Item 24 of the Form N-2 Registration Statement under the Securities Act of 1933,
as amended (the "1933 Act"), and the Investment Company Act of 1940, as amended
(the "1940 Act").

          In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Notification
of



                                        2

Registration of the Trust as an investment company under the 1940 Act on Form
N-8A, dated February 19, 2003, as filed with the Securities and Exchange
Commission (the "Commission") on February 19, 2003, (ii) the registration
statement of the Trust on Form N-2, 1933 Act File No. 333-105785 and 1940 Act
File No. 811-21309, as filed with the Commission on June 2, 2003, under the 1933
Act and the 1940 Act, and as amended by Pre-Effective Amendment No. 1 thereto on
July 16, 2003, and Pre-Effective Amendment No. 2 thereto on July 21, 2003 (such
Registration Statement being hereinafter referred to as the "Registration
Statement"); (iii) the form of Purchase Agreement proposed to be entered into
between the Trust, as issuer, and Merrill Lynch, Pierce, Fenner & Smith
Incorporated as representative of the underwriters named therein (the
"Underwriters"), filed as an exhibit to the Registration Statement; (iv) a
specimen certificate representing the AMPS; (v) the Certificate of Trust and the
Agreement and Declaration of Trust of the Trust, dated February 19, 2003, and as
currently in effect (the "Declaration"); (vi) the Statement of Preferences
setting forth the rights, powers, terms and preferences of the AMPS; (vii) the
By-Laws of the Trust, as currently in effect; and (viii) certain resolutions
adopted by the Board of Trustees of the Trust relating to the issuance and sale
of the AMPS and related matters. We also have examined originals or copies,
certified or otherwise identified to our satisfaction, of such records of the
Trust and such agreements, certificates of public officials, certificates of
officers or other representatives of the Trust and others, and such other
documents, certificates and records as we have deemed necessary or appropriate
as a basis for the opinions set forth herein.

          In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies and the
authenticity of the originals of such copies. In making our examination of
documents, we have assumed that the parties thereto, other than the Trust, had
the power, corporate or other, to enter into and perform all obligations
thereunder and have also assumed the due authorization by all requisite action,
corporate or other, and execution and delivery by such parties of such documents
and the validity and binding effect thereof on such parties. In rendering the
opinion set forth below, we have assumed that the share certificate representing
the AMPS will conform to the specimen examined by us and will have been manually
signed by an authorized officer of the transfer agent and registrar for the AMPS
and registered by such transfer agent and registrar. As to any facts material to
the opinions expressed herein which we have not independently established or
verified, we have relied upon statements and representations of officers and
other representatives of the Trust and others.



                                        3

          In rendering the opinion set forth below, we have assumed that any
AMPS issued to a Principal Shareholder (as that term is defined in Section 11.7
of the Declaration) will be issued in compliance with Section 11.7 of the
Declaration.

          Members of our firm are admitted to the bar in the State of Delaware
and we do not express any opinion as to the laws of any jurisdiction other than
the Delaware Statutory Trust Act.

          Based upon and subject to the foregoing, we are of the opinion that
when (i) the Registration Statement becomes effective; (ii) the Purchase
Agreement has been duly executed and delivered; (iii) a certificate representing
the AMPS in the form of the specimen certificate examined by us has been
manually signed by an authorized officer of the transfer agent and registrar for
the AMPS and registered by such transfer agent and registrar; and (iv) the AMPS
have been delivered to and paid for by the Underwriters at a price per share not
less than the per share par value of the AMPS as contemplated by the purchase
agreement, the issuance and sale of the AMPS will have been duly authorized, and
the AMPS will be validly issued, fully paid and nonassessable (except as
provided in the last sentence of Section 3.8 of the Declaration).

          We hereby consent to the filing of this opinion with the Securities
and Exchange Commission (the "Commission") as an exhibit to the Registration
Statement. We also consent to the reference to our firm under the caption "Legal
Opinions" in the Registration Statement. In giving this consent, we do not
thereby admit that we are included in the category of persons whose consent is
required under Section 7 of the 1933 Act or the rules and regulations of the
Commission.

                                    Very truly yours,

                                    /s/ Skadden, Arps, Slate, Meagher & Flom LLP
