Ladies and Gentlemen:

Enbridge Energy Partners, L.P., a Delaware limited partnership (the “Partnership”), proposes, upon the terms and subject to the conditions set forth herein, to issue and sell to the several Underwriters named in Schedule IA hereto (the “Underwriters”), $200,000,000 aggregate principal amount of its 4% Notes due 2009 (the “Notes”). The Notes are to be issued pursuant to an indenture dated as of May 27, 2003, between the Partnership and SunTrust Bank, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture thereto dated as of May 27, 2003, by the Second Supplemental Indenture thereto dated as of May 27, 2003, and by the Third Supplemental Indenture thereto to be dated as of January 9, 2004 (as so supplemented, the “Indenture”).

Each of the Partnership and Enbridge Energy, Limited Partnership, a Delaware limited partnership and subsidiary of the Partnership (the “Operating Partnership”), wishes to confirm as follows its agreement with the Underwriters in connection with their several purchases of the Notes. The Partnership, the Operating Partnership, Enbridge Energy Company, Inc., a Delaware corporation (both in its capacity as general partner of the Partnership and in its individual capacity, the “General Partner”), and Enbridge Energy Management, L.L.C., a Delaware limited

liability company (“Enbridge Management”), are sometimes collectively referred to herein as the “Companies.”

1. Registration Statement and Prospectus. The Partnership has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”), a registration statement on Form S-3 (Registration No. 333-106660) under the Act, including a prospectus subject to completion relating to the Notes. Such registration statement (including all financial schedules and exhibits), as supplemented or amended prior to the execution of this Agreement is herein called the “Registration Statement.” If it is contemplated, at the time this Agreement is executed, that a post-effective amendment to such registration statement will be filed and must be declared effective before the offering of the Notes may commence, the term “Registration Statement” as used in this Agreement means such registration statement as amended by said post-effective amendment. If it is contemplated, at the time this Agreement is executed, that a registration statement will be filed pursuant to Rule 462(b) under the Act before the offering of the Notes may commence, the term “Registration Statement” as used in this Agreement includes such registration statement. The term “Basic Prospectus” as used in this Agreement shall mean the prospectus contained in the Registration Statement at the time that the Registration Statement was declared effective or in the form in which it has been most recently filed with the Commission on or prior to the date of this Agreement. The term “Final Prospectus” shall mean the prospectus supplement relating to the Notes and the offering thereof that is first filed pursuant to Rule 424(b) under the Act (“Rule 424(b)”) after the date and time this Agreement is executed and delivered by the parties hereto, together with the Basic Prospectus.

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, the Basic Prospectus or the Final Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, the Basic Prospectus or the Final Prospectus, as the case may be; any reference in this Agreement to the Registration Statement, the Basic Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act, as of the date of the Registration Statement, the Basic Prospectus or the Final Prospectus, as the case may be; and any reference to any amendment or supplement to the Registration Statement, the Basic Prospectus or the Final Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the “Exchange Act”) which, upon filing, are incorporated by reference therein, as required by paragraph (b) of Item 12 of Form S-3. As used herein, the term “Incorporated Documents” means the documents which at the time are incorporated by reference in the Registration Statement, the Basic Prospectus or the Final Prospectus or any amendment or supplement thereto.

2. Agreements to Sell and Purchase. The Partnership hereby agrees, upon the terms and subject to all the conditions set forth herein, to issue and sell to the Underwriters and, upon the basis of the representations, warranties and agreements of the Partnership and the Operating Partnership herein contained and upon the terms and subject to all the conditions set forth herein, each Underwriter agrees, severally and not jointly, to purchase from the Partnership, at the

applicable purchase price set forth in Schedule IB hereto, the aggregate principal amount of the Notes set forth opposite such Initial Purchaser’s name in Schedule IA hereto.

3. Terms of Public Offering. The Partnership has been advised by you that the Underwriters propose to make a public offering of their respective portion of the Notes as soon after the Registration Statement and this Agreement have become effective as in your judgment is advisable and initially to offer the Notes upon the terms set forth in the Final Prospectus.

4. Delivery of the Notes and Payment Therefor. The Notes to be purchased hereunder will be represented by one or more definitive global certificates in book-entry form which will be deposited by or on behalf of the Partnership with The Depository Trust Company (“DTC”) or its designated custodian.

Delivery to the Underwriters of the Notes, against payment of the purchase price therefor in immediately available funds, shall be made by causing DTC to credit the Notes to the account or accounts designated by Wachovia Capital Markets, LLC on behalf of the Underwriters at DTC. The time and date of such delivery shall be 10:00 A.M., New York City time, on January 9, 2004 (the “Closing Date”). The other documents to be delivered at the Closing Date by or on behalf of the parties hereto shall be delivered at such time and date at the offices of Baker Botts L.L.P., 910 Louisiana, Houston, Texas 77002.

5. Agreements of the Partnership. The Partnership agrees with the several Underwriters as follows:

(a) If, at the time this Agreement is executed and delivered, it is necessary for the Registration Statement or a post-effective amendment thereto to be declared effective before the offering of the Notes may commence, the Partnership will endeavor to cause the Registration Statement or such post-effective amendment to become effective as soon as possible and will advise you and counsel for the Underwriters promptly and, if requested by you, will confirm such advice in writing, when the Registration Statement or such post-effective amendment has become effective.

(b) Following the execution and delivery of this Agreement and thereafter from time to time during such period as in the opinion of counsel for the Underwriters a prospectus is required by the Act to be delivered in connection with sales by the Underwriters or any dealer (the “Prospectus Delivery Period”), the Partnership will advise you and counsel for the Underwriters promptly and, if requested by you, will confirm such advice in writing: (i) of any request by the Commission for amendment of or a supplement to the Registration Statement, the Basic Prospectus or the Final Prospectus or for additional information; (ii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of the suspension of qualification of the Notes for offering or sale in any jurisdiction or the initiation of any proceeding for such purpose; and (iii) of any change in the financial position, business, prospects, or results of operations of any of the Companies, or of the happening of any event, which makes any statement of a material fact made in the Registration Statement or the

Final Prospectus (as then amended or supplemented) untrue or which requires the making of any additions to or changes in the Registration Statement or the Final Prospectus (as then amended or supplemented) in order to state a material fact required by the Act to be stated therein or necessary in order to make the statements therein not misleading, or of the necessity to amend or supplement the Final Prospectus (as then amended or supplemented) to comply with the Act or any other law. If at any time within the Prospectus Delivery Period, the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, the Partnership will make every reasonable effort to obtain the withdrawal of such order at the earliest possible time.

(c) The Partnership will furnish to you, at your request and without charge, (i) one conformed copy of the Registration Statement as originally filed with the Commission and of each amendment thereto, including financial statements and all exhibits to the Registration Statement, (ii) such number of conformed copies of the Registration Statement as originally filed and of each amendment thereto, but without exhibits, as you may request, (iii) such number of copies of the Incorporated Documents, without exhibits, as you may request, and (iv) such number of copies of the exhibits to the Incorporated Documents as you may request.

(d) During the Prospectus Delivery Period, the Partnership will not file any amendment to the Registration Statement or make any amendment or supplement to the Final Prospectus or, file any document which, upon filing becomes an Incorporated Document, of which you and counsel for the Underwriters shall not previously have been advised or to which, after you and counsel for the Underwriters shall have received a copy of the document proposed to be filed, you shall reasonably object; provided that your consent shall not be unreasonably withheld or delayed.

(e) [Reserved]

(f) The Partnership will cause the Final Prospectus to be filed pursuant to, and in compliance with, Rule 424(b). As soon as practical following the execution and delivery of this Agreement and until the end of the Prospectus Delivery Period, the Partnership will expeditiously deliver to the Underwriters and each dealer, without charge, as many copies of the Final Prospectus (and of any amendment or supplement thereto) as you may reasonably request. The Partnership consents to the use of the Final Prospectus (and of any amendment or supplement thereto) in accordance with the provisions of the Act and with the securities or Blue Sky laws of the jurisdictions in which the Notes are offered by the Underwriters and by all dealers to whom Notes may be sold, both in connection with the issuance and sale of the Notes and for such period of time thereafter as the Final Prospectus is required by the Act to be delivered in connection with sales by the Underwriters or any dealer. If during such period of time any event shall occur that in the judgment of the Partnership or in the opinion of counsel for the Underwriters is required to be set forth in the Final Prospectus (as then amended or supplemented) or should be set forth therein in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Final Prospectus (or to file under the Exchange Act any document which, upon filing, becomes an Incorporated Document) in order to comply with the Act or any other law, the Partnership will forthwith prepare and, subject to the provisions of paragraph (d) above, file with the Commission an appropriate supplement or amendment thereto (or to such document), and will expeditiously furnish to the Underwriters and dealers a reasonable number of copies thereof. In the event that the Partnership and the Underwriters agree that the Final Prospectus should be amended or supplemented, the Partnership, if requested by you, will

promptly issue a press release announcing or disclosing the matters to be covered by the proposed amendment or supplement.

(g) The Partnership will cooperate with you and with counsel for the Underwriters in connection with the registration or qualification of the Notes for issuance and sale by the Underwriters and by dealers under the securities or Blue Sky laws of such jurisdictions as you may designate and will file such consents to service of process or other documents necessary or appropriate in order to effect such registration or qualification; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action which would subject it to service of process in suits, other than those arising out of the offering or sale of the Notes, in any jurisdiction where it is not now so subject.

(h) The Partnership will make generally available to security holders of the Partnership a consolidated earnings statement, which need not be audited, covering a 12-month period commencing after the effective date of the Registration Statement and ending not later than 15 months thereafter, as soon as practicable after the end of such period, which consolidated earnings statement shall satisfy the provisions of Section 11(a) of the Act.

(i) If this Agreement shall terminate or shall be terminated after execution pursuant to any provisions hereof (otherwise than pursuant to Section 10 hereof or pursuant to clause (ii), (iii), (iv) or (v) of Section 11 hereof) or if this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Partnership or the Operating Partnership to comply with the terms or fulfill any of the conditions of this Agreement, each of the Partnership and the Operating Partnership, jointly and severally, agree to reimburse the Underwriters for all out-of-pocket expenses (including reasonable fees and expenses of counsel for the Underwriters) incurred by the Underwriters in connection herewith.

(m) The Partnership, during the Prospectus Delivery Period, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act.

(z) The Companies and the Operating Subsidiaries and their properties, assets and operations are in compliance with, and hold all permits, authorizations and approvals required under, Environmental Laws (as defined below), except to the extent that failure to so comply or to hold such permits, authorizations or approvals would not, individually or in the aggregate, have a Material Adverse Effect. Except as disclosed in the Registration Statement and the Final Prospectus (or any amendment or supplement thereto), there are no past, present or, to the knowledge of the Companies after due inquiry, reasonably anticipated future events, conditions, circumstances, activities, practices, actions, omissions or plans that could reasonably be expected to give rise to any material costs or liabilities to the Companies or the Operating Subsidiaries under, or to interfere with or prevent compliance by the Companies or the Operating Subsidiaries with, Environmental Laws; except as would not, individually or in the aggregate, have a Material Adverse Effect. Except as disclosed in the Registration Statement and the Final Prospectus (or any amendment or supplement thereto), none of the Companies nor any of the Operating Subsidiaries (i) is the subject of any investigation, (ii) has received any notice or claim, (iii) is a party to or affected by any pending or threatened action, suit or proceeding, (iv) is bound by any judgment, decree or order, or (v) has entered into any agreement, in each case relating to any alleged violation of any Environmental Law or any actual or alleged release or threatened release or cleanup at any location of any Hazardous Materials (as defined below) (as used herein, “Environmental Law” means any federal, state, local or foreign law, statute, ordinance, rule, regulation, order, decree, judgment, injunction, permit, license, authorization or other binding requirement, or common law, relating to health, safety or the protection, cleanup or restoration of the environment or natural resources, including those relating to the distribution, processing, generation, treatment, storage, disposal, transportation, other handling or release or threatened release of Hazardous Materials, and “Hazardous Materials” means any material (including, without limitation, pollutants, contaminants, hazardous or toxic substances or wastes) that is regulated by or may give rise to liability under any Environmental Law).

7. Indemnification and Contribution.

(a) Each of the Partnership and the Operating Partnership, jointly and severally, agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Final Prospectus or in the Registration Statement or in any amendment or supplement thereto, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or expenses arise out of or are based upon any untrue statement or omission or alleged untrue statement or omission which has been made therein or omitted therefrom in reliance upon and in conformity with the information relating to such Underwriter furnished in writing to the Partnership by or on behalf of the Underwriter expressly for use in connection therewith; provided, however, that the only information furnished in writing to the Partnership by or on behalf of the Underwriters are the statements noted in Section 12 hereof. The foregoing indemnity agreement shall be in addition to any liability which any of the Partnership or the Operating Partnership may otherwise have.

(b) If any action, suit or proceeding shall be brought against any Underwriter or any person controlling any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act in respect of which indemnity may be sought against the Partnership or the Operating Partnership, such Underwriter or such controlling person shall promptly notify Enbridge Management on behalf of the Partnership and the Operating Partnership, and the Partnership and the Operating Partnership shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Underwriters and payment of all fees and expenses. Such Underwriter or any such controlling person shall have the right to employ separate counsel in any such action, suit or proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless (i) the Partnership has agreed in writing to pay such fees and expenses, (ii) the Partnership and the Operating Partnership have failed to assume the defense and employ counsel reasonably satisfactory to the Underwriters or (iii) the named parties to any such action, suit or proceeding (including any impleaded parties) include both such Underwriter or such controlling person and any of the Partnership or the Operating Partnership and such Underwriter or such controlling person shall have been advised by its counsel that representation of such indemnified party and the Partnership or the Operating Partnership by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them (in which case the Partnership and the Operating Partnership shall not have the right to assume the defense of such action, suit or proceeding on behalf of such

Underwriter or such controlling person). It is understood, however, that the Partnership and the Operating Partnership shall, in connection with any one such action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Underwriters and controlling persons not having actual or potential differing interests with you, which firm shall be designated in writing by Deutsche Bank Securities Inc. and Wachovia Capital Markets, LLC, and that all such fees and expenses shall be reimbursed as they are incurred. Neither the Partnership nor the Operating Partnership shall be liable for any settlement of any such action, suit or proceeding effected without its written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, suit or proceeding, each of the Partnership and the Operating Partnership, jointly and severally, agrees to indemnify and hold harmless any Underwriter, to the extent provided in the preceding paragraph, and any such controlling person from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless each of the Partnership and the Operating Partnership, the directors and officers of the General Partner and of Enbridge Management, and any person who controls any of the Partnership and the Operating Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Partnership and the Operating Partnership to each Underwriter, but only with respect to information relating to such Underwriter furnished in writing by or on behalf of such Underwriter expressly for use in the Registration Statement, the Final Prospectus, or any amendment or supplement thereto; provided, however, that the only information furnished in writing to the Partnership by or on behalf of the Underwriters are the statements noted in Section 12 hereof. If any action, suit or proceeding shall be brought against any of the Partnership and the Operating Partnership, any of the directors and officers of the General Partner and of Enbridge Management, or any such controlling person based on the Registration Statement or the Final Prospectus, or any amendment or supplement thereto, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph (c), such Underwriter shall have the rights and duties given to the Partnership and the Operating Partnership by paragraph (b) above, and the Partnership and the Operating Partnership, the directors and officers of the General Partner and of Enbridge Management, and any such controlling person, shall have the rights and duties given to the Underwriters by paragraph (b) above. The foregoing indemnity agreement shall be in addition to any liability which the Underwriters may otherwise have.

(d) If the indemnification provided for in this Section 7 is unavailable to an indemnified party under paragraphs (a) or (c) hereof in respect of any losses, claims, damages, liabilities or expenses referred to therein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership and the Operating Partnership on the one hand and the Underwriters on the other hand from the offering of the Notes, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership and the Operating Partnership on the one hand and the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant

equitable considerations. The relative benefits received by the Partnership and the Operating Partnership on the one hand and the Underwriters on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Final Prospectus. The relative fault of the Partnership and the Operating Partnership on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership and the Operating Partnership on the one hand or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, including, with respect to any Underwriter, the extent to which any such loss, claim, damage or liability arises from the sale of Notes by such Underwriter to any person if a copy of the Final Prospectus shall not have been delivered or sent to such person within the time required by the Act, provided that the Partnership has delivered the Final Prospectus to the several Underwriters in requisite quantities on a timely basis to permit such delivery or sending.

(e) The Partnership, the Operating Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by a pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating any claim or defending any such action, suit or proceeding. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price of the Notes underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to the respective principal amount of Notes set forth opposite their names in Schedule IA hereto (or such principal amount of Notes increased as set forth in Section 10 hereof) and not joint.

(f) No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 7 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Partnership set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of

any Underwriter or any person controlling any Underwriter, either the Partnership or the Operating Partnership, the directors or officers of the General Partner and Enbridge Management, or any person controlling either the Partnership or the Operating Partnership, (ii) acceptance of any Notes and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter or any person controlling any Underwriter, or to the Partnership or the Operating Partnership or the directors or officers of the General Partner and Enbridge Management, or any person controlling either the Partnership or the Operating Partnership, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 7. The term “successor,” as used in this Agreement, shall not include a purchaser from any Underwriter of any Notes in his status as a purchaser.

8. Conditions of Underwriters’ Obligations. The several obligations of the Underwriters to purchase the Notes hereunder are subject to the following conditions:

(xi) The Notes are in the form contemplated by the Indenture and have been duly authorized, executed and delivered by the Partnership and, when authenticated in accordance with the terms of the Indenture and paid for by the Underwriters in accordance with the terms of this Agreement, will constitute valid and legally binding obligations of the Partnership, enforceable against the Partnership in accordance with their terms under the laws of the State of New York, 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).

(xiv) 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 the Partnership or the Operating Partnership under the Delaware LP Act, Texas law, the contract laws of the State of New York, or federal law for the valid issuance and sale of the Notes to the Underwriters as contemplated by this Agreement, the execution and delivery of this Agreement, the Indenture and the Notes, or the incurrence or performance of their obligations hereunder and thereunder, except (i) such as may be required under Blue Sky laws, as to which such counsel need not express an opinion, and (ii) such others as have been obtained or taken and are in full force and effect..

(xx) To the knowledge of such counsel and without in any manner having conducted an investigation, there are no material legal or governmental proceedings pending or threatened against any of the Companies or the Operating Subsidiaries (other than any proceedings with respect to the Partnership’s liquids pipeline operations, as to which such counsel need not express any opinion) by or before the FERC or on appeal from the FERC, except as set forth in or contemplated by the Final Prospectus.

Such counsel shall also state that although such counsel has not undertaken, except as otherwise indicated in their opinion, to determine independently, and does not assume any responsibility for, the accuracy or completeness of the statements in the Registration Statement, such counsel has reviewed and is familiar with the Registration Statement and has participated in the preparation of the Final Prospectus, including review and discussion of the contents thereof (including review and discussion of the contents of all Incorporated Documents), and nothing has come to the attention of such counsel that has caused them to believe that the Registration Statement (including the Incorporated Documents) at the time the Registration Statement became effective, or the Final Prospectus, as of its date and as of the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that any amendment or supplement to

the Final Prospectus, as of its respective date, and as of the Closing Date, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that such counsel need express no opinion with respect to the financial statements and the notes thereto and the schedules and other financial data included in the Registration Statement or the Final Prospectus or any Incorporated Document).

In rendering such opinions, such counsel may (1) rely in respect of factual matters upon representations and warranties of the Companies set forth herein and certificates of officers of Enbridge Management and upon information obtained from public officials, upon opinions of other counsel issued in connection with the offering of the Notes pursuant to the Final Prospectus and other sources believed by such counsel to be responsible, (2) state that their opinion is limited to federal laws, the Delaware Act, the Delaware General Corporation Law, the Delaware Limited Liability Company Act and New York 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 the following clauses (e), (f) and (g), (3) state that they 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 or the Operating Subsidiaries may be subject and (4) state that their opinion is furnished as counsel for the Partnership and the Operating Partnership to you, and is solely for the benefit of the several Underwriters.

(e) You shall have received on the Closing Date an opinion of Sullivan & Cromwell L.L.P., counsel for the Partnership and the Operating Partnership, dated the Closing Date and addressed to you, to the effect that (i) none of the Companies is (A) a “subsidiary company” of a “registered holding company,” or of a “holding company” required to be registered under the 1935 Act or (B) is 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, and (ii) 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 Notes by the Partnership as contemplated by the Final Prospectus.

(f) Fraser Trebilcock Davis and Dunlap, P.C., acting as special local counsel for the Partnership and the Operating Partnership with respect to the State of Michigan, shall have furnished to you, its written opinion or opinions, dated as of the Closing Date in form and substance satisfactory to you, to the effect that:

(i) Neither the offer, sale or delivery of the Notes, the execution, delivery or performance of this Agreement, the Indenture and the Notes, compliance by the Partnership and the Operating Partnership with the provisions hereof or thereof nor consummation by the Partnership and the Operating Partnership of the transactions contemplated hereby or thereby will result in any violation of any existing law, regulation, ruling (assuming compliance with all applicable state securities and Blue Sky laws), judgment, injunction, order or decree known to such counsel after reasonable inquiry, applicable to any of the Companies or any of their respective properties.

(ii) No consent, approval, authorization, order, registration or qualification of or with any governmental agency or instrumentality of such state governing (A) oil pipelines generally or (B) the issuance of securities by entities owning

oil pipelines, or, to such counsel’s knowledge, based solely upon its participation as special counsel in matters relating to the issue and sale of the Notes pursuant to the Final Prospectus and without in any manner having conducted an independent investigation, any other governmental agency or instrumentality of such state having jurisdiction over any of the Companies, as the case may be, or any of their respective properties, is required for the sale or issuance of the Notes by the Partnership, except such consents, approvals, authorizations, orders, registrations or qualifications (1) as have been obtained, (2) as may be required under state securities or Blue Sky laws, (3) which, if not obtained, would not, individually or in the aggregate, have a material adverse effect upon the ability of the Partnership and the Operating Partnership (taken as a whole) to conduct their business substantially in accordance with the past practice of each, or (4) as set forth or contemplated in the Final Prospectus.

(g) You shall have received on the Closing Date an opinion of Steptoe & Johnson, special FERC counsel for the Partnership and the Operating Partnership, dated the Closing Date and addressed to you, to the effect that:

(i) No consent, approval, authorization, order, registration or qualification of or with the FERC with respect to the Partnership’s liquids pipeline operations is required for the issuance of the Notes, the offer and sale of the Notes by the Partnership or the execution, delivery and performance of this Agreement, the Indenture and the Notes.

(ii) To the knowledge of such counsel and without in any manner having conducted an investigation, there are no material legal or governmental proceedings relating to the Partnership’s liquids pipelines operations pending or threatened against any of the Companies or the Operating Subsidiaries by or before the FERC or on appeal from the FERC, except as set forth in or contemplated by the Final Prospectus.

(h) [Reserved]

(i) You shall have received on the Closing Date an opinion of Baker Botts L.L.P., counsel for the Underwriters, dated the Closing Date, with respect to the matters referred to in clauses (i) (but only with respect to the Companies), (vi), (vii), (viii), (ix), (x), (xi), (xii) and (xv) (but only with respect to the Registration Statement and the Final Prospectus and any supplements or amendments thereto) of the foregoing paragraph (d) and such other related matters as the Underwriters may request.

(j) You shall have received letters addressed to you and dated the date hereof and the Closing Date from PricewaterhouseCoopers LLP, independent accountants, substantially in the forms heretofore approved by you.

(k) (i) No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been taken or, to the knowledge of any of the Companies shall be threatened by the Commission at or prior to the Closing Date; (ii) there shall not have been any change in the capitalization of the Partnership nor any material increase in the short-term or long-term debt of the Partnership (other than in the ordinary course of business) from that set forth or contemplated in the Registration Statement or

the Final Prospectus (or any amendment or supplement thereto); (iii) none of the Companies shall have any liabilities or obligations, direct or contingent (whether or not in the ordinary course of business), that are material to the General Partner or the Partnership and the Operating Subsidiaries (taken as a whole), other than those reflected in the Registration Statement or the Final Prospectus (or any amendment or supplement thereto); and (iv) all the representations and warranties of the Partnership contained in this Agreement shall be true and correct on and as of the date hereof and on and as of the Closing Date as if made on and as of the Closing Date, and you shall have received a certificate, dated the Closing Date and signed by the chief executive officer and the chief financial officer of Enbridge Management (or such other officers as are acceptable to you), to the effect set forth in this Section 8(k) and in Section 8(l) hereof and with respect to the foreign qualifications of the Companies and the Material Operating Subsidiaries.

(l) Neither the Partnership nor the Operating Partnership shall have failed at or prior to the Closing Date to have performed or complied with any of its agreements herein contained and required to be performed or complied with by it hereunder at or prior to the Closing Date.

(m) At the Closing Date, the Notes shall be rated at least “Baa2” by Moody’s Investors Services Inc. and “BBB” by Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., and the Partnership shall have delivered to the Underwriters a letter dated near the Closing Date, from each such rating agency, or other evidence satisfactory to the Underwriters, confirming that the Notes have such ratings; and since the date of this Agreement, there shall not have occurred a downgrading in the rating assigned to the Notes below Baa2/BBB or any of the Partnership’s or the Operating Partnership’s other debt securities by any “nationally recognized statistical rating agency,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and no such organization shall have publicly announced that it has under surveillance or review its rating of the Notes or any of the Partnership’s or the Operating Partnership’s other debt securities.

(n) Each of the Partnership and the General Partner shall have furnished or caused to be furnished to you such further certificates and documents as you shall have reasonably requested that are customary in closing transactions of the nature contemplated by this Agreement.

(o) You shall have received on the Closing Date an opinion of Vinson & Elkins L.L.P., counsel for the Partnership and the Operating Partnership, dated the Closing Date and addressed to you, stating that although such counsel has not undertaken, except as otherwise indicated in their opinion, to determine independently, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements in the Final Prospectus, such counsel has (i) reviewed various background documents and items of correspondence identified or provided to such counsel by the Companies; (ii) interviewed and participated in discussions with officers, employees, and other representatives of the Companies; (iii) interviewed and participated in discussions with certain of the legal and financial advisors to the Special Committee of the board of directors of the General Partner that negotiated the acquisition of the Midcoast, Northeast Texas, and South Texas systems; (iv) reviewed with the lead underwriter of Enbridge Management’s initial public offering certain issues relating to the initial public offering; and (v) participated in discussion with the staff of the Commission, and nothing has come to the attention of such counsel that has caused them to believe that the Final Prospectus, as of its date and as of the Closing Date, contained an untrue statement of a material fact

regarding the Commission’s informal inquiry into the Partnership’s acquisition of its Midcoast, Northeast Texas and South Texas Systems and the initial public offering of Enbridge Management (the “Informal Inquiry”) or omitted to state a material fact regarding the Informal Inquiry required to be stated therein or necessary to make the statements therein regarding the Informal Inquiry, in the light of the circumstances under which they were made, not misleading or that any amendment or supplement to the Final Prospectus, as of its respective date, and as of the Closing Date, contained any untrue statement of a material fact regarding the Informal Inquiry or omitted to state a material fact regarding the Informal Inquiry necessary in order to make the statements therein regarding the Informal Inquiry, in the light of the circumstances under which they were made, not misleading.

All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof only if they are satisfactory in form and substance to you and counsel for the Underwriters.

Any certificate or document signed by any officer of the General Partner or of Enbridge Management, whether on behalf of itself or the Partnership, and delivered to you or to counsel for the Underwriters, shall be deemed a representation and warranty by the Partnership to the Underwriters as to the statements made therein.

9. Expenses. The Partnership and the Operating Partnership agree to pay on a joint and several basis the following costs and expenses and all other costs and expenses incident to the performance by them of their obligations hereunder: (i) the preparation of the Indenture, the issuance of the Notes and the fees of the Trustee, (ii) the preparation, printing or reproduction, and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), the Final Prospectus, each amendment or supplement to any of them and this Agreement; (iii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, the Basic Prospectus, the Final Prospectus, the Incorporated Documents, and all amendments or supplements to any of them, as may be reasonably requested for use in connection with the issuance and sale of the Notes; (iv) the preparation, printing, authentication, issuance and delivery of certificates for the Notes; (v) the printing (or reproduction) and delivery of this Agreement, any Agreement among Underwriters, the Indenture, any preliminary or supplemental Blue Sky Memoranda and all other agreements or documents printed (or reproduced) and delivered in connection with the issuance of the Notes; (vi) the rating of the Notes; (vii) the registration or qualification of the Notes for issuance and sale under the securities or Blue Sky laws of the several states as provided in Section 5(g) hereof, if required (including the reasonable fees, expenses and disbursements of counsel for the Underwriters relating to the preparation, printing or reproduction, and delivery of any preliminary or supplemental Blue Sky Memoranda and such registration and qualification); (viii) the filing fees and the fees and expenses of counsel for the Underwriters in connection with any filings required to be made with the National Association of Securities Dealers, Inc.; (ix) the transportation and lodging expenses incurred by or on behalf of representatives of the Partnership in connection with any presentations to prospective purchasers of the Notes; (x) the fees and expenses of the accountants for the Companies; (xi) the fees and expenses of counsel (including local and special counsel) for the Companies; and (xii) any fees payable to DTC in connection with the Notes being book-entry only securities.

10. Effective Date of Agreement. This Agreement shall become effective: (i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at the time this Agreement is executed and delivered, it is necessary for the Registration Statement or a post-effective amendment thereto to be declared effective before the offering of the Notes may commence, when notification of the effectiveness of the Registration Statement or such post-effective amendment has been given by the Commission. Until such time as this Agreement shall have become effective, it may be terminated by Enbridge Management, on behalf of the Partnership by notifying you, or by you by notifying Enbridge Management, on behalf of the Partnership.

If any one or more of the Underwriters shall fail or refuse to purchase Notes which it or they are obligated to purchase hereunder on the Closing Date, and the aggregate principal amount of the Notes which such defaulting Underwriter or Underwriters are obligated but fail or refuse to purchase is not more than one tenth of the aggregate principal amount of the Notes which the Underwriters are obligated to purchase on the Closing Date, each non-defaulting Underwriter shall be obligated, severally, in the proportion which the principal amount of the Notes set forth opposite its name in Schedule IA hereto bears to the aggregate principal amount of the Notes set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in accordance with the Master Agreement Among Underwriters relating to the offering of the Notes, to purchase the principal amount of the Notes which such defaulting Underwriter or Underwriters are obligated, but fail or refuse, to purchase. If any one or more of the Underwriters shall fail or refuse to purchase Notes which it or they are obligated to purchase on the Closing Date and the aggregate principal amount of the Notes with respect to which such default occurs is more than one tenth of the aggregate principal amount of the Notes which the Underwriters are obligated to purchase on the Closing Date and arrangements satisfactory to you and the Partnership for the purchase of such principal amount of the Notes by one or more non defaulting Underwriters or other party or parties approved by you and the Partnership are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any party hereto (other than the defaulting Underwriter). In any such case which does not result in termination of this Agreement, either you or the Partnership shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement. The term “Underwriter” as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule IA hereto who, with your approval and the approval of the Partnership, purchases Notes which a defaulting Underwriter is obligated, but fails or refuses, to purchase.

Any notice under this Section 10 may be made by telegram, telecopy or telephone but shall be subsequently confirmed by letter.

11. Termination of Agreement. This Agreement shall be subject to termination in your absolute discretion, without liability on the part of any Underwriter to the Partnership and the Operating Partnership by notice to Enbridge Management, on behalf of the Partnership and the Operating Partnership, if prior to the Closing Date: (i) there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Final Prospectus, any material adverse change in the financial position, results of operations, business or prospects of the Partnership and the Operating Subsidiaries (taken as a whole), whether or not arising in the ordinary course of business; (ii) trading in the Class A Common

Units of the Partnership or the publicly traded shares representing limited liability company interests in Enbridge Management shall be suspended or subject to any restriction or limitation not in effect on the date of this Agreement; (iii) trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market shall have been suspended or materially limited; (iv) a general moratorium on commercial banking activities in New York shall have been declared by either federal or state authorities or there shall have been a material disruption in commercial banking or securities settlement or clearance services in the United States; or (v) there shall have occurred any material adverse change in the financial markets in the United States or Canada, any outbreak or escalation of hostilities or the declaration by the United States of a national emergency or war or other international or domestic calamity, crisis or change in political, financial or economic conditions, the effect of which on the financial markets of the United States is such as to make it, in your judgment, impracticable or inadvisable to commence or continue the offering of the Notes on the terms set forth on the cover page of the Final Prospectus or to enforce contracts for the resale of the Notes by the Underwriters. Notice of such termination shall be promptly given to Enbridge Management, on behalf of the Partnership and the Operation Partnership, by telegram, telecopy or telephone and shall be subsequently confirmed by letter.

12. Information Furnished by the Underwriters . The statements set forth in the last paragraph on the cover page and the statements in the fourth, fifth and twelfth paragraphs, and the last sentence of the eighth paragraph, under the caption “Underwriting” in the Final Prospectus, constitute the only information furnished by or on behalf of the Underwriters as such information is referred to in Sections 6(a), 6(b) and 7 hereof.

13. Miscellaneous . Except as otherwise provided in Sections 5, 10 and 11 hereof, notice given pursuant to any provision of this Agreement shall be in writing and shall be delivered (i) if to either the Partnership or the Operating Partnership, at the office of the General Partner, at 1100 Louisiana, Suite 3300, Houston, Texas 77002, Attention: E. Chris Kaitson, Corporate Secretary; or (ii) if to the Underwriters, care of: Deutsche Bank Securities Inc., 60 Wall Street, New York, New York 10005, Attention: Corporate Finance Department; and Wachovia Capital Markets, LLC, One Wachovia Center, 301 South College Street, Charlotte, North Carolina 28288, Attention: Head of Investment Grade Syndicate.

This Agreement has been and is made solely for the benefit of the several Underwriters, the Partnership, the Operating Partnership, the directors and officers of the General Partner and Enbridge Management, and the other controlling persons referred to in Section 7 hereof and their respective successors and assigns, to the extent provided herein, and no other person shall acquire or have any right under or by virtue of this Agreement. Neither the term “successor” nor the term “successors and assigns” as used in this Agreement shall include a purchaser from any Underwriter of any of the Notes in his status as such purchaser.

14. Applicable Law; Counterparts. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

This Agreement may be signed in various counterparts which together constitute one and the same instrument. If signed in counterparts, this Agreement shall not become effective unless at least one counterpart hereof shall have been executed and delivered on behalf of each party hereto.

15. Representations, Warranties and Agreements to Survive Delivery . All representations, warranties and agreements contained in this Agreement or in certificates of officers of the General Partner and Enbridge Management submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Companies, and shall survive delivery of the Notes to the Underwriters.

16. Disclosure Regarding Tax Matters. Notwithstanding anything herein to the contrary, each of the Partnership, the Operating Partnership, the General Partner, Enbridge Management and the Underwriters (and each employee, representative or other agent of the foregoing persons), subject to applicable law, may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and tax structure of this potential transaction and all materials of any kind (including tax opinions and other tax analyses) that are provided to such persons relating to such tax treatment and tax structure.

17. Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and each of the Partnership and the Operating Partnership consents to the jurisdiction of such courts and personal service with respect thereto. Each of the Partnership and the Operating Partnership hereby consents to personal jurisdiction, service and venue in any court in which any claim arising out of or in any way relating to this Agreement is brought by any third party against Deutsche Bank Securities Inc., Wachovia Capital Markets, LLC or any indemnified party. Each of Deutsche Bank Securities Inc. and Wachovia Capital Markets, LLC and each of the Partnership and the Operating Partnership (on their behalf and, to the extent permitted by applicable law, on behalf of its unitholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. Each of the Partnership and the Operating Partnership agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon each of the Partnership and the Operating Partnership, as applicable, and may be enforced in any other courts to the jurisdiction of which each of the Partnership and the Operating Partnership, as applicable, is or may be subject, by suit upon such judgment.

Please confirm that the foregoing correctly sets forth the agreement among the Partnership, the Operating Partnership and the several Underwriters.
