Ladies and Gentlemen:
We have acted as counsel to Martin Midstream Partners L.P., a Delaware limited partnership
(the “Partnership”), with respect to certain legal matters in connection with the offer and
sale by the Partnership of its common units representing limited partner interests (the “Common
Units”). We have also participated in the preparation of the Partnership’s Prospectus
Supplement, dated May 15, 2007 (the “Prospectus Supplement”), and Prospectus, dated July 19,
2004 (the “Prospectus”), both relating to the Common Units and forming a part of the
Partnership’s Registration Statement on Form S-3 (File No. 333-117023) (the “Registration
Statement”). At your request, this opinion is being furnished to you for filing as an exhibit
to the Partnership’s Current Report on Form 8-K filed with the Securities and Exchange
Commission (the “SEC) on or about the date hereof.
In connection therewith, we prepared the discussion set forth under the captions “Material
Tax Considerations” (the “Discussion”) in both the Prospectus Supplement and the Prospectus.
All statements of legal conclusions contained in the Discussion, unless otherwise noted,
are our opinion with respect to the matters set forth therein (i) as of the date of the
Prospectus in respect of the discussion set forth under the caption “Material Tax
Considerations” in the Prospectus and (ii) as of the date of the Prospectus Supplement in
respect of the discussion set forth under the caption “Material Tax Considerations” in the
Prospectus Supplement, in both cases qualified by the limitations, and subject to the
assumptions and qualifications contained in the Discussion. In addition, we are of the opinion
that the Discussion in the Registration Statement with respect to those matters as to which no
legal conclusions are provided is an accurate discussion, as of each of the aforementioned
dates, of such federal income tax matters (except for the representations and statements of
fact of the Partnership and its general partner included in the Discussion, as to which we
express no opinion).
We hereby consent to the filing of this opinion as an exhibit to the Current Report on
Form 8-K referred to above and to the use of our name in the Discussion in the Prospectus
Supplement and the Prospectus. In giving this consent, we do not hereby admit
