Based on the foregoing, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that the Units, when issued, will be validly
issued, fully paid and non-assessable, except as such non-assessability may be affected by Sections
17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act (the Delaware LP
Act) and as described in the Prospectus.
The foregoing opinion is limited to the Delaware LP Act (including the applicable provisions
of the Delaware Constitution and the reported judicial decisions interpreting these laws) and the
federal laws of the United States of America. We are expressing no opinion as to the effect of the
laws of any other jurisdiction, domestic or foreign.
We hereby consent to the filing of this opinion as an exhibit to the Registration Statement
and to the use of our name in the Prospectus forming a part of the Registration Statement under the
caption Legal Matters. In giving this consent, we do not admit that we are within the category of
persons whose consent is required under Section 7 of the Securities Act and the rules and
regulations thereunder.
Very truly yours,
