(iv) such other papers, documents, agreements, certificates of public officials and certificates of representatives of the Partnership and the General Partner as we have deemed relevant and necessary as the basis for the opinion hereafter expressed.

reviewed by us in connection with the rendering of the opinion set forth herein are true, correct and complete and (e) the truthfulness of each statement as to all factual matters contained in any document or certificate encompassed within the due diligence review undertaken by us.

In rendering this opinion, we have also assumed:

(i) that the issuance and sale of the Units complies in all respects with the terms, conditions and restrictions set forth in the Prospectus and all of the instruments and other documents relating thereto or executed in connection therewith;

(ii) that the Underwriting Agreement has been duly and validly authorized by the Partnership, the General Partner and the other parties thereto, and executed and delivered by such parties; and

(iii) the validity and enforceability of the Underwriting Agreement against the parties thereto.

As to matters of fact material to this opinion that have not been independently established, we have relied upon the representations and certificates of officers or representatives of each of the Partnership Entities and of public officials, in each case as we have deemed relevant and appropriate, and upon the representations and warranties of each of the Partnership Entities in the Underwriting Agreement. We have not independently verified the facts so relied on.

This opinion letter is limited to Marshall Islands Law and is as of the date hereof. We expressly disclaim any responsibility to advise of any development or circumstance of any kind, including any change of law or fact that may occur after the date of this opinion letter that might affect the opinion expressed herein.

Based on the foregoing, and having regard to legal considerations which we deem relevant, and subject to the qualifications, limitations and assumptions set forth herein, we are of the opinion that when the Units are issued and delivered against payment therefor in accordance with the terms of the Underwriting Agreement, the Registration Statement and the Prospectus, such Units will be validly issued, fully paid and nonassessable.

We consent to the filing of this opinion as an exhibit to the Registration Statement, the discussion of this opinion in the Registration Statement and to the references to our firm in the Prospectus. In giving this consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended (the “Securities Act”), or the rules and regulations promulgated thereunder, nor do we admit that we are experts with respect to any part of the Registration Statement within the meaning of the term “expert” as used in the Securities Act.

Very truly yours,
