         -------------------------------------------------------

Ladies and Gentlemen:

     We have served as counsel for UBS Financial Services Inc. as sponsor and
depositor ("Sponsor") of Equity Opportunity Trust, Value Select Ten Series 2007C
("Trust") in connection with the preparation, execution and delivery of the
Standard Terms & Conditions of the Trust dated July 1, 1998, as amended, and the
Trust Indenture dated as of May 18, 2007 between the Depositor, and Investors
Bank & Trust Company, as Trustee ("Trustee") pursuant to which the Depositor has
deposited the securities listed in Schedule A to the Trust Indenture
("Securities") and pursuant to which the Trust has issued an initial 1,000,000
units of fractional undivided interest in the Trust ("Units").

     In this regard, we have examined executed originals or copies of the

     By-Laws of the Sponsor, as amended, certified by the Secretary of the
     Sponsor on the date hereof;



          (b) Resolutions of the Board of Directors of the Sponsor adopted on

          (d) Resolutions of the Board of Directors of the Sponsor adopted on
     June 9, 2003, certified by the Secretary of the Sponsor on the date hereof;

          (e) Powers of Attorney as set forth in the certificate of the
     Secretary of the Sponsor dated the date hereof;

          (f) The Registration Statement ("Registration Statement") on Form S-6
     (File No. 333-142364) filed with the Securities and Exchange Commission
     ("Commission") in accordance with the Securities Act of 1933, as amended,
     and the rules and regulations of the Commission promulgated thereunder
     (collectively, the "1933 Act") and amendments thereto including Amendment
     No. 1 ("Amendment No. 1") proposed to be filed on May 18, 2007 (the
     "Registration Statement");

          (g) The Notification of Registration of the Trust filed with the
     Commission under the Investment Company Act of 1940, as amended (the "1940
     Act") on Form N-8A, as amended;

          (h) The registration of the Trust filed with the Commission under the
     1940 Act on Form N-8B-2 (File No. 811-3722), as amended;

          (i) The prospectus included in Amendment No. 1 ("Prospectus");

          (j) The Standard Terms and Conditions of the Trust dated as of July 1,
     1998, as amended, executed by the Sponsor and Investors Bank & Trust
     Company ("Trustee") ("Standard Terms");

          (k) The Trust Indenture dated as of May 18, 2007 between the Sponsor
     and the Trustee ("Trust Indenture" and, collectively with the Standard
     Terms, "Indenture and Agreement");

          (l) The Closing Memorandum dated May 18, 2007 between the Sponsor and
     the Trustee ("Closing Memorandum");

          (m) Officers Certificates required by the Closing Memorandum; and

          (n) Such other pertinent records and documents as we have deemed
     necessary.

     With your permission, in such examination, we have assumed the following:
(a) the authenticity of original documents and the genuineness of all
signatures; (b) the conformity to the originals of all documents submitted to us
as copies; (c) the truth, accuracy, and completeness of the



information, representations, and warranties contained in the records,
documents, instruments and certificates we have reviewed; (d) except as
specifically covered in the opinions set forth below, the due authorization,
execution, and delivery on behalf of the respective parties thereto of documents
referred to herein and the legal, valid, and binding effect thereof on such
parties; and (e) the absence of any evidence extrinsic to the provisions of the
written agreement(s) between the parties that the parties intended a meaning
contrary to that expressed by those provisions. However, we have not examined
the Securities nor the contracts for the Securities.

     We express no opinion as to matters of law in jurisdictions other than the
laws of the State of New York (except for "Blue Sky" laws) and the federal laws
of the United States, except to the extent necessary to render the opinion as to
the Sponsor and the Indenture and Agreement in paragraphs (i) and (iii) below
with respect to Delaware law. As you know we are not licensed to practice law in
the State of Delaware, and our opinion in paragraphs (i) and (iii) as to
Delaware law is based solely on review of the General Corporation Law of the
State of Delaware.

     Based upon such examination, and having regard for legal considerations
which we deem relevant, we are of the opinion that:

     (i) The Sponsor is a corporation duly organized, validly existing, and in
good standing under the laws of the State of Delaware with full corporate power
to conduct its business as described in the Prospectus;

     (ii) The Sponsor is duly qualified as a foreign corporation and is in good
standing as such within the State of New York;

     (iii) The Indenture and Agreement has been duly authorized, executed and
delivered by the Sponsor and, assuming the due authorization, execution and
delivery by the Trustee, is a valid and binding agreement of the Sponsor,
enforceable against the Sponsor in accordance with its terms;

     (iv) The Trust has been duly formed and is validly existing as an
investment trust under the laws of the State of New York and has been duly
registered under the Investment Company Act of 1940;

     (v) The terms and provisions of the Units conform in all material respects
to the description thereof contained in the Prospectus;

     (vi) The consummation of the transactions contemplated under the Indenture
and Agreement and the fulfillment of the terms thereof will not be in violation
of the Sponsor's Restated Certificate of Incorporation, as amended, or By-Laws,
as amended and will not conflict with any applicable laws or regulations
applicable to the Sponsor in effect on the date hereof;

     (vii) The Units to be issued by the Trust, and recorded on its registration
books in accordance with the Indenture and Agreement against payment therefor,
as described in the Registration Statement and Prospectus will constitute
fractional undivided interests in the Trust



enforceable against the Trust in accordance with their terms, will be entitled
to the benefits of the Indenture and Agreement and will be fully paid and
non-assessable; and

     (viii) While the Registration Statement has not yet become effective we
have no reason to believe that it will not become effective on the date and at
the time requested therein pursuant to Rule 487 promulgated under the 1933 Act.

     In addition, we have participated in conferences with representatives of
the Sponsor, the Trustee, the Trust's independent registered public accountants
and others concerning the Registration Statement and the Prospectus and have
considered the matters required to be stated therein and the statements
contained therein, although we have not independently verified the accuracy,
completeness or fairness of such statements. Based upon and subject to the
foregoing, nothing has come to our attention to cause us to believe that the
Registration Statement, as of the date hereof, contained an untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, or that the
Prospectus, as of the date hereof, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading (it being understood that we have not
been requested to and do not make any comment in this paragraph with respect to
the financial statements, schedules and other financial and statistical
information contained in the Registration Statement or the Prospectus).

     Our opinion that any document is valid, binding, or enforceable in
accordance with its terms is qualified as to:

     (a) limitations imposed by bankruptcy, insolvency, reorganization,
arrangement, fraudulent conveyance, moratorium, or other laws relating to or
affecting the enforcement of creditors' rights generally;

     (b) rights to indemnification and contribution which may be limited by
applicable law or equitable principles; and

     (c) general principles of equity, regardless of whether such enforceability
is considered in a proceeding in equity or at law.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever it appears in the
Registration Statement and the Prospectus.

                                   Very truly yours,

                                   /s/ KATTEN MUCHIN ROSENMAN LLP
