Dear Sirs:
We have acted as counsel to Enbridge Energy Partners, L.P., a Delaware limited partnership (the “Partnership”), in connection with the proposed offering by the Partnership of $400,000,000 aggregate principal amount of its 8.05% Fixed/Floating Rate Junior Subordinated Notes due 2067 (the “Notes”). The Notes are to be issued pursuant to an Indenture to be dated September 27, 2007, as amended by the First Supplemental Indenture thereto to be dated September 27, 2007 (as so amended and supplemented, the “Indenture”), between the Partnership and U.S. Bank National Association, as trustee, which establishes the forms and terms of the Notes pursuant to the Indenture. We refer to the registration statement on Form S-3 (Registration No. 333-131076) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) by the Partnership on January 17, 2006, including the base prospectus contained therein, and the prospectus supplement (the “Prospectus Supplement”) filed with the Commission on September 25, 2007, relating to the offering of the Notes.
As counsel to the Partnership, we have examined such corporate records, documents and questions of law as we have deemed necessary or appropriate for the purposes of this opinion. In such examinations, we have assumed the genuineness of signatures and the conformity to the originals of the documents supplied to us as copies. As to various questions of fact material to this opinion, we have relied upon statements and certificates of officers and representatives of the Partnership. Without limiting the foregoing, we have examined the Underwriting Agreement, dated September 24, 2007 (the “Underwriting Agreement”), among the Partnership and Merrill Lynch, Pierce, Fenner & Smith Incorporated, Lehman Brothers Inc. and Wachovia Capital Markets, LLC, as representatives of the underwriters named on Schedule I thereto (the “Underwriters”).
Based upon the foregoing, and subject to the limitations, qualifications, assumptions and exceptions stated herein, we are of the opinion that the Notes have been duly authorized and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will, under the laws of the State of New York, constitute legal and binding obligations of the
Partnership. We express no opinion as to the binding effect or enforceability of any provisions exculpating a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves gross negligence, recklessness, willful misconduct or unlawful conduct.
The opinions expressed herein are limited exclusively to the General Corporation Law of the State of Delaware, the Delaware Revised Uniform Limited Partnership Act, the Delaware Limited Liability Company Act and the applicable provisions of the Delaware constitution and reported decisions concerning such laws, the laws of the State of Texas, the laws of the State of New York and the federal laws of the United States of America, and we are expressing no opinion as to the effect of the laws of any other jurisdiction. We hereby consent to the filing of this opinion as an Exhibit to the Registration Statement and to the references to us under “Legal Matters” in the Prospectus Supplement.
| Very truly yours, |
