Enbridge agrees to indemnify each Purchaser and its Representatives (collectively, the “Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of Enbridge contained herein, provided such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of such representation or warranty.

Section 5.02 Indemnification by Purchasers. Each Purchaser agrees, severally and not jointly, to indemnify the Companies and their respective Representatives (collectively, the “Enbridge Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of such Purchaser contained herein, provided such claim for indemnification relating to a breach of the representations and warranties is made prior to the expiration of such representations and warranties.

Section 5.03 Indemnification Procedure. Promptly after any Enbridge Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense and employ counsel or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, the Indemnified Party.

ARTICLE VI.

Ladies and Gentlemen:

We have acted as counsel to Enbridge Energy Partners, L.P., a Delaware limited Partnership (the “Enbridge”), in connection with the offer and sale to you by Enbridge of an aggregate of 2,506,500 Class A Common Units representing limited partner interests in Enbridge (the “Purchased Units”) pursuant to a Common Unit Purchase Agreement, dated February 9, 2005 (the “Common Unit Purchase Agreement”), among Enbridge, Enbridge Energy Company, Inc., a Delaware corporation (the “General Partner” and, together with Enbridge, the “Companies”), and you.

In our capacity as counsel to Enbridge, we have reviewed and are familiar with the registration statement on Form S-3 (No. 333-106660) of Enbridge that was filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), and the General Rules and Regulations promulgated thereunder (the “Rules and Regulations”). Such registration statement, as supplemented or amended through September 9, 2004, including all documents filed as part thereof or incorporated by reference therein, are referred to herein as the “Registration Statement”. In addition, we are familiar with the base prospectus, dated August 5, 2003, and have participated in the preparation of the prospectus supplement, dated February 9, 2005, in each case in the form filed by Enbridge with the Commission on February 10, 2005, pursuant to Rule 424(b) of the Rules and Regulations. Such base prospectus and prospectus supplement are referred to herein as the “Final Prospectus”.

This opinion is being delivered pursuant to Section 2.05(h) of the Common Unit Purchase Agreement. Capitalized terms used in this opinion without definition shall have the meanings assigned to such terms in the Common Unit Purchase Agreement.

In connection with the opinions expressed below, we have examined the following:

(h) signed copies of the Registration Statement;

Based on the foregoing and subject to the qualifications and limitations set forth below, we are of the opinion that:

(i) Each of Enbridge, the General Partner, Enbridge Management, and each of the Material Subsidiaries (collectively, the “Enbridge Parties”) listed on Schedule IA hereto (“Schedule IA”) is a corporation, limited partnership or limited liability company, as the case may be, duly incorporated or formed, as the case may be, validly existing and in good standing under the laws of its jurisdiction of incorporation or formation, as the case may be, with full corporate, limited partnership or limited liability company power and authority, as the case may be, to own and lease its properties and to conduct its business as is now conducted and as described in the Final Prospectus and, in the case of the General Partner, to act as the general partner of Enbridge.

(ii) Enbridge is the record owner of all of the issued and outstanding shares of capital stock of the General Partner.

(iii) The authorized and outstanding partnership interests of Enbridge are as set forth under the caption “Prospectus Supplement Summary—Enbridge Partners—Business Description” in the Final Prospectus.

(iv) The General Partner is the sole general partner of Enbridge. The capitalization of Enbridge consists of (a) 48,208,884 Common Units, consisting of 44,296,134 Class A Common Units and 3,912,750 Class B Common Units, all of which Class B Common Units are owned of record and, to our knowledge, beneficially owned by the General Partner, (b) a 2% general partner interest, which is owned of record and, to our knowledge, beneficially owned by the General Partner, and (c) 10,902,408 i-units, all of which are owned of record and, to our knowledge, beneficially owned by Enbridge Management. The i-units that are owned by Enbridge Management, the 2% general partner interest that is owned by the General Partner and the shares representing a voting limited liability company interest in Enbridge Management that is owned by the General Partner are each owned free and clear, to our knowledge, of any lien, encumbrance, security interest, equity or charge (“Lien”) (1) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming Enbridge Management or the General Partner as a debtor is on file in the Office of the Secretary of the State of Delaware or (2) in each case other than (A) those created by or arising under the Delaware Act, the Delaware LLC Act or the Delaware General Corporation Law (“DGCL”), (B) Liens as are not, individually or in the aggregate, material to such interest ownership or (C) as described in the Final Prospectus. The capitalization of Enbridge Management consists of 10,902,408 shares representing limited liability company interests with limited voting rights and one share representing a voting limited liability company interest, which voting limited liability company interest is owned of record and, to our knowledge, beneficially owned by the General Partner. To our knowledge, the securities described in the second and fourth sentences of this paragraph are the only equity securities of Enbridge and Enbridge Management that are issued and outstanding. The Class A Common Units, Class B Common Units and i-units of Enbridge and the voting shares of Enbridge Management have been duly and validly authorized and issued and are fully paid and nonassessable. The general partner interest in Enbridge has been duly and validly authorized and issued and fully paid.

(v) The outstanding limited liability company interests, partnership interests, or other equity interests, as applicable, of each of the Material Subsidiaries listed on Schedule IA are owned of record and, to our knowledge, beneficially owned by Enbridge, directly or indirectly, through one or more wholly owned subsidiaries, free and clear, to our knowledge, of any Lien (a) in respect of which a financing statement under the Uniform Commercial Code of the state of formation of the entities listed on Schedule IA naming any such entity as a debtor is on file in the Office of the Secretary of the state of formation of such entities or (b) in each case other than (1) those created by or arising under the Delaware LLC Act, the Delaware Act, the Texas Limited Liability Company Act or the Texas Revised Limited Partnership Act, (2) Liens as are not, individually or in the aggregate, material to such ownership interest or (3) as described in the Final Prospectus. All of the limited liability company interests, partnership interests and other equity interests, as applicable, of each of the Material Subsidiaries listed on Schedule IA have been duly and validly authorized and issued and fully paid and, except with respect to any general partner interest, nonassessable. To our knowledge, none of the outstanding limited liability company interests, partnership interests, or other equity interests, as the case may be, of any of the Material Subsidiaries listed on Schedule IA were issued in violation of any preemptive rights of any holder of any security or other interest in such entities.

(vi) The Purchased Units to be issued and sold to you by Enbridge hereunder have been duly authorized by Enbridge and, when issued and delivered to you against payment therefor in accordance with the terms of the Common Unit Common Unit Purchase Agreement, will be validly issued, fully paid and nonassessable (except as such nonassessability may be affected by the matters described in the Form 8-A), and free of any preemptive or similar rights (except for any required Capital Contributions to Enbridge to be made by the General Partner pursuant to Section 4.4(c)(ii) of the Partnership Agreement) that entitle or will entitle any person to acquire any partnership interest in Enbridge, upon the issuance thereof by Enbridge, arising under the Partnership Agreement or, to our knowledge without any independent investigation, any other agreement to which Enbridge is a party or by which it is bound, and you will acquire the Purchased Units free and clear of any liens, encumbrances, security interests, charges or claims of record known (based solely upon our participation as counsel in matters relating to the offering of the Purchased Units and without having conducted an independent investigation) to us, except as created by the Common Unit Common Unit Purchase Agreement or you or any person who acquires an interest in the Purchased Units through you or as provided by the Delaware Act.

(vii) Enbridge has the partnership power and authority to enter into the Common Unit Purchase Agreement and, to issue, sell and deliver the Purchased Units to you as provided therein.

(viii) The Common Unit Purchase Agreement has been duly authorized and validly executed and delivered by or on behalf of the Companies, and are enforceable against the Companies, except as the enforceability thereof may be limited by bankruptcy, fraudulent transfer, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(ix) Neither the offer, sale or delivery of the Purchased Units, the execution, delivery or performance of the Basic Documents, compliance by Enbridge with the provisions thereof nor consummation by Enbridge of the transactions contemplated thereby violate the Partnership Agreement or constitute a breach of, or default under, any agreement, indenture, lease or other instrument to which Enbridge, the General Partner or Enbridge Management is a party or by which any of them may be bound or to which any of their respective properties is subject that is (a) an exhibit to the Registration Statement or to any Incorporated Document, or (b) a long-term debt instrument representing greater than $10 million aggregate principal amount of indebtedness that is not filed as an exhibit to any document incorporated therein pursuant to Item 601(b)(4)(iii)(A) of Regulation S-K under the Securities Act (the “Incorporated Documents”), nor will any such action result in any violation of any existing law, regulation, ruling (assuming compliance with all applicable federal and state securities and Blue Sky laws) applicable to any of them, or any judgment, injunction, order or decree to which any of the Enbridge Parties is a named party and which has been specifically identified to us in a certificate signed by an authorized officer of Enbridge, excluding in each case (other than with respect to the Partnership Agreement) any breaches, defaults or violations which, individually or in the aggregate, would not have an Enbridge Material Adverse Effect; except for the rights of the General Partner and its Affiliates (as such term is defined in the Partnership Agreement and used in Section 6.14 of the Partnership Agreement), to our knowledge, neither the filing of the Registration Statement nor the offering or sale of the Purchased Units as contemplated by the Basic Documents gives rise to any rights for or relating to the registration of any interests in or securities of any of the Enbridge Parties.

(x) No approval, authorization, consent, waiver, notice or order of, or filing with, or other action by, any court or any governmental authority is required to be obtained or made by Enbridge under the Delaware Act, Texas law, the contract laws of the State of Delaware, or federal law for the valid offering and sale of the Purchased Units to the Purchasers as contemplated by the Common Unit Purchase Agreement, the execution and delivery of the Common Unit Purchase Agreement, or the incurrence or performance of their obligations thereunder, except (i) such as may be required under Blue Sky laws, as to which we express no opinion, and (ii) such others as have been obtained or taken and are in full force and effect.

(xi) To our knowledge, (a) other than as described or contemplated in the Final Prospectus (or any amendment or supplement thereto) or any Incorporated Document, there are no legal or governmental proceedings pending or threatened against any of the Enbridge Parties, or to which any of the Enbridge Parties or any of their property, is subject, which are required to be described in the Registration Statement or the Final Prospectus (or any amendment or supplement thereto) and (b) there are no agreements, contracts, indentures, leases or other instruments, that are required to be described in the Registration Statement or the Final Prospectus (or any amendment or supplement thereto) or to be filed as an exhibit to the Registration Statement or any Incorporated Document that are not described or filed as required, as the case may be.

(xii) None of the Enbridge Parties is an “Investment Company” as that term is defined in the Investment Company Act or is required to register as an “Investment Company” under the Investment Company Act.

(xiii) Our tax opinion relating to the Purchased Units that was filed as Exhibit 8.1 to Enbridge’s Current Report on Form 8-K filed with the Commission on February 10, 2005, is confirmed, and you may rely upon such opinion as if it were addressed to you.

(xiv) The Registration Statement and all post-effective amendments thereto, if any, have become effective under the Securities Act, and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Final Prospectus pursuant to Rule 424(b) has been made in accordance with Rule 424(b).

(xv) The Registration Statement and the Final Prospectus and any supplements or amendments thereto (except for the financial statements and the notes thereto and the schedules and other financial data included therein, as to which we express no opinion) comply as to form in all material respects with the requirements of the Securities Act; and each of the Incorporated Documents (except for the financial statements and the notes thereto and the schedules and other financial data included therein, as to which we express no opinion) complies as to form in all material respects with the Exchange Act.

(xvi) None of the Enbridge Parties is a “public utility company” or a “holding company” as such terms are defined in the 1935 Act.

(xvii) To our knowledge, and without in any manner having conducted an investigation, there are no material legal or governmental proceedings pending or threatened against any of the Enbridge Parties by or before the Federal Energy Regulatory Commission (the “FERC”) or on appeal from the FERC, except as set forth in or contemplated by the Final Prospectus.

(xviii) The Partnership Agreement has been duly authorized, executed and delivered by the General Partner and is a valid and legally binding agreement of the General Partner, enforceable against the General Partner in accordance with its terms, subject to the qualifications that (a) the enforceability of such document may be limited by bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors’ rights generally, (b) the enforceability of such document may be limited by public policy, applicable law relating to fiduciary duties and the judicial imposition of an implied covenant of good faith and fair dealing, (c) the enforceability of equitable rights and remedies provided for in such document is subject to equitable defenses and judicial discretion, and the enforceability of such document may be limited by general equitable principles, and (d) the enforceability of the indemnity and contribution provisions of such document may be limited by federal and state securities laws.

In rendering the foregoing opinions, (i) we have relied in respect of factual matters upon representations and warranties of the Companies set forth in the Common Unit Purchase Agreement and certificates of officers of the General Partner and Enbridge Management and upon information obtained from public officials and other sources believed by us to be responsible, (ii) we express no opinion with respect to state or local taxes or tax statutes to which any of the Partnership, the limited partners of the Partnership, the Operating Subsidiaries or the General Partner may be subject and (iii) we have assumed, with your approval and without independent verification, (a) that the certificates for the Purchased Units have been duly registered by a registrar of the Units, (b) the authenticity of all documents submitted to us as originals, (c) the conformity to the authentic originals of all documents submitted to us as copies, (d) the due authorization, execution and delivery of all relevant documents by parties other than the Enbridge Parties, (e) that the signatures on all documents examined by us are genuine and (f) the legal capacity of all individuals signing documents examined by us. Further, the foregoing opinions are subject to the effect of generally applicable rules of law that may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed exchange. In addition, in rendering the opinion in paragraph (ix) above, we have relied without investigation upon a certificate of an officer of the General Partner as to compliance with covenants of a financial or numerical nature contained in the agreements, credit agreements, indentures, leases or other instruments referred to in paragraph (ix) above.

This opinion is limited in all respects to federal laws, the Delaware Act, the DGCL, the Delaware LLC Act and Texas law (exclusive of pipeline and pipeline-related regulatory law), in each case exclusive of the law addressed in the legal opinions rendered by counsel referred to in Section 2.05(j) of the Common Unit Purchase Agreement.

As used herein, the phrase “to our knowledge” or words of similar import means conscious awareness of facts or other information by the lawyers in our firm who, based on our records as of 12:00 p.m. on February 5, 2005, have devoted substantive attention to legal matters on behalf of the Companies since January 1, 2004. With your consent, we have not examined any records of any court, administrative tribunal or similar entity.

This opinion is furnished by us as counsel for the Companies solely for the benefit of the Underwriter and may not be relied upon by any other person or entity or furnished to anyone else without the prior written consent of the undersigned, except that the transfer agent for the Purchased Units may rely upon this opinion in connection with those transactions.

Very truly yours,

Fulbright & Jaworski L.L.P.

Ladies and Gentlemen:

I am Associate General Counsel and Assistant Corporate Secretary of Enbridge Energy Company, Inc., a Delaware corporation (the “General Partner”), and in such capacity have acted as Associate General Counsel and Assistant Corporate Secretary to the General Partner, Enbridge Energy Partners, L.P., a Delaware limited partnership (the “Partnership”) and Enbridge Energy Management, Inc., a Delaware limited liability company (“Enbridge Management”) and the Operating Subsidiaries, in connection with the issuance and sale by the Partnership of an aggregate of 2,506,500 Class A Common Units representing limited partner interests in the Partnership to each of you pursuant to the terms and conditions set forth in the Common Unit Purchase Agreement dated February 9, 2005 (the “Purchase Agreement”), among the you, the Partnership and the General Partner. The Partnership, the Operating Partnership, Enbridge Management and the General Partner are sometimes collectively referred to herein as the “Enbridge Companies.”

This opinion is being delivered pursuant to Section 2.05(i) of the Purchase Agreement. Capitalized terms used in this opinion without definition shall have the meanings assigned to such terms in the Purchase Agreement.

I have examined such corporate and partnership records and documents of the Enbridge Companies, together with such instruments and certificates of public officials, as I have deemed necessary for the purpose of rendering the opinions set forth herein.

Based on the foregoing and subject to the qualifications and limitations set forth below, I am of the opinion that:

(i) There is no action, proceeding or investigation pending or, to the best of my knowledge after due inquiry, threatened against any of the Enbridge Parties (i) which in my judgment could reasonably be expected to have an Enbridge Material Adverse Effect or (ii) that questions the validity of the Purchase Agreement or the Partnership Agreement or the right of Enbridge to enter into the Purchase Agreement.

(ii) None of the Enbridge Parties is in violation of any term of (A) its partnership agreement, limited liability company agreement, or certificate of incorporation or by-laws or other organizational documents, as the case may be, (B) any other material agreement or instrument to which it is a party or by which it or any of its properties is bound, or (C) to the best of my knowledge after due inquiry, any applicable order, judgment or decree of any court, arbitrator or governmental authority to which any of the Enbridge Parties is a named party, which violations, in my judgment, could reasonably be expected to have an Enbridge Material Adverse Effect or to adversely impact the enforceability or validity of the Common Unit Purchase Agreement.

(iii) To my knowledge, except as described in the Registration Statement, there are no outstanding or authorized (i) options, warrants, preemptive rights, subscriptions, calls, or other rights, convertible or exchangeable securities, agreements, claims or commitments of any character obligating any of the Enbridge Parties to issue, transfer or sell any partnership interests or other equity interest in, any of the Enbridge Parties or securities convertible into or exchangeable for such partnership interests, (ii) obligations of any of the Enbridge Parties to repurchase, redeem or otherwise acquire any partnership interests or equity interests of any of the Enbridge Parties or any such securities or agreements listed in clause (i) of this sentence or (iii) voting trusts or similar agreements to which any of the Enbridge Parties is a party with respect to the voting of the equity interests of any of the Enbridge Parties. To my knowledge, none of the filing of the Registration Statement or the offering or sale of the Common Units, all as contemplated by the Purchase Agreement, gives rise to any rights for or relating to the registration of any Common Units or other securities of Enbridge. The rights of the General Partners have been waived.

I am qualified to practice law in the State of Texas, and this opinion is limited in all respects to the federal laws of the United States, the Delaware Revised Uniform Limited Partnership Act, the Delaware General Corporation Law, the Delaware Limited Liability Company Act and the Laws of the State of Texas.

This opinion is furnished as counsel for the Enbridge Parties to you and is solely for your benefit and may not be relied upon by any other person or entity or furnished to anyone else without the prior written consent of the undersigned.

Very truly yours,

Chris Kaitson
Associate General Counsel and
Assistant Corporate Secretary

See Attached

12 February 11, 2005

To the Purchasers named in Annex A hereto:

In connection with the purchase today by you, pursuant to the Common Unit Purchase Agreement dated February 9, 2005 between Enbridge Energy Partners, L.P. (the “Partnership”), Enbridge Energy Company, Inc. (the “General Partner”) and you (the “Purchase Agreement”), of 2,506,500 Class A Common Units (the “Securities”) of the Partnership, we, as special counsel for the Partnership, Enbridge Energy, Limited Partnership (the “Operating Partnership”), the General Partner and Enbridge Energy Management, L.L.C. (“Management”, and together with the Partnership, the Operating Partnership and the General Partner, the “Companies”) have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that:

(1) None of the Companies is (i) a “subsidiary company” of a “registered holding company” or of a “holding company” required to be registered under the Public Utility Holding Company Act of 1935, as amended (the “1935 Act”), or (ii) an “affiliate” of a “registered holding company” or of a “holding company” required to be registered under the 1935 Act, or of a “subsidiary company” of a “registered holding company” or of a “holding company” required to be registered under the 1935 Act, as such terms are defined in the 1935 Act.

(2) No consent, authorization, approval or filing is required to be obtained or made under the 1935 Act in connection with the issuance and sale of the Securities by the Partnership as contemplated by the Final Prospectus (as defined in the Purchase Agreement).

The foregoing opinion is limited to the Federal laws of the United States and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

In rendering the foregoing opinion, we have relied as to certain matters on information obtained from officers of the Companies and Enbridge Inc., the parent corporation of the General Partner (“Enbridge”), and have assumed that (i) none of the Companies or the Operating Subsidiaries (as defined in the Underwriting Agreement) is a “public utility company” or a “holding company” as such terms are defined in the 1935 Act (as to which matters you are receiving an opinion from Fulbright & Jaworski L.L.P.), and (ii) no “holding company” (other than Enbridge and Noverco Inc.) and no “subsidiary company” or “affiliate” of a “holding company” (other than subsidiaries of Enbridge) directly or indirectly owns, controls or holds with power to vote 5% or more of the outstanding voting securities of the Partnership, Management or Enbridge or of Enbridge’s 32%-owned affiliate Noverco Inc. or of Noverco Inc.’s 77%-owned subsidiary Gaz Metropolitain and Company, Limited Partnership.

This letter is furnished to you by us as special counsel for the Companies and is solely for your benefit.

Very truly yours,
