1. Interest. Enbridge Energy Partners, L.P., a Delaware limited partnership (the “Partnership” or the “Issuer”), promises to pay interest on the principal amount of this Note at

5.35% per annum from December 3, 2004 until maturity. The Issuer shall pay interest semi-annually on December 15 and June 15 of each such year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be

June 15, 2005. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the same rate; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. The Issuer shall pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the December 1 and June 1 immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.17 of the Original Indenture with respect to Defaulted Interest, and the Issuer shall pay principal (and premium, if any) of the Notes upon surrender thereof to the Trustee or a paying agent on or after the Stated Maturity thereof. The Notes shall be payable as to principal, premium, if any, and interest at the office or agency of the Trustee maintained for such purpose (which initially is c/o SunTrust ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ Capital Markets, 3^rd Floor, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇), or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, and interest and premium, if any, on, (a) each Global Security and (b) all other Notes aggregating at least $1,000,000 in principal amount the Holder of which shall have provided wire transfer instructions to the Issuer or the paying agent on or prior to the applicable record date. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

3. Paying Agent and Registrar. Initially, SunTrust Bank, the Trustee under the Indenture, shall act as paying agent and Registrar. The Issuer may change any paying agent or Registrar without notice to any Holder. The Partnership may act in any such capacity.

4. Indenture. The Issuer issued the Notes under an Indenture dated as of May 27, 2003 (the “Original Indenture”), as supplemented by the Fourth Supplemental Indenture dated as of December 3, 2004 (the “Supplemental Indenture” and, together with the Original Indenture, the “Indenture”), between the Issuer and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are the obligation of the Issuer, initially in aggregate principal amount of $200 million. The Issuer may issue an unlimited aggregate principal amount of Additional Notes under the Indenture. Any such Additional Notes that are actually issued shall be treated as issued and outstanding Notes (and as the same series (with identical terms other than with respect to the issue date, issue price and first payment of interest) as the initial Note for the purposes indicated in Section 3.02 of the Supplemental Indenture). Initially, the Notes are not guaranteed, but in the future they may be guaranteed by one or more Subsidiary Guarantors on the conditions and subject to the terms provided in Section 4.13 and Article XIV of the Indenture.

5. Optional Redemption. (a) At its option, the Issuer may choose to redeem all or any portion of the Notes, at once or from time to time.

(b) To redeem the Notes, the Issuer must pay a redemption price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis points, plus, in either case, accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date).

For purposes of determining the redemption price, the following definitions shall apply:

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of the Notes to be redeemed.

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of four Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means either Deutsche Bank Securities Inc. or Wachovia Capital Markets, LLC, as specified by the Partnership, and any successor firm, or if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Trustee after consultation with the Partnership.

“Reference Treasury Dealer” means each of Deutsche Bank Securities Inc. and Wachovia Capital Markets, LLC, plus two other dealers selected by the Trustee that are primary U.S. government securities dealers in New York City and their respective successors; provided, if any of Deutsche Bank Securities Inc. or Wachovia Capital Markets, LLC or any primary U.S. government securities dealer selected by the Trustee shall cease to be a primary U.S. government securities dealer, then such other primary U.S. government securities dealers as may be substituted by the Trustee.

“Reference Treasury Dealer Quotations” means, for each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes to be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week in which the calculation date falls (or in the immediately preceding week if the calculation date falls on any day prior to the usual publication date for such release) or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. Any weekly average yields calculated by interpolation or extrapolation will be rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above being rounded upward.

6. Mandatory Redemption. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase them at the option of the Holders.

7. Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption and with respect to which the redemption price has been paid.

8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay any taxes or other governmental charges imposed in relation thereto.

9. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.

10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture may be amended or supplemented with the consent of the Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes, and any existing default or compliance with any provision of the Indenture relating to the Notes may be waived with the consent of the Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes. Without the consent of any Holder of a Note, the Indenture may be amended or supplemented for any of the purposes set forth in Section 9.01 of the Indenture, including to cure any ambiguity, defect or inconsistency, to provide for the assumption of the Issuer’s obligations to Holders of the Notes in case of a merger or consolidation of the Issuer or sale of all or substantially all of the Issuer’s assets, to add or release Subsidiary Guarantors pursuant to the terms of the Indenture, to make any change that does not adversely affect the rights under the Indenture of any Holder of the Notes, to comply with the requirements of the SEC to permit the qualification of the Indenture under the TIA, to evidence or provide for the acceptance of appointment under the Indenture of a successor or separate Trustee, to add to the covenants of the Issuer or any Subsidiary Guarantor, to secure the Notes or the Guarantee or to establish the form or terms of any other series of Debt Securities.

11. Defaults and Remedies. Events of Default with respect to the Notes include: (i) default for 30 days in the payment when due of interest on, the Notes; (ii) default in payment when due of principal of or premium, if any, on the Notes when due at Stated Maturity, upon redemption or otherwise; (iii) failure by the Partnership or any Subsidiary Guarantor for 60 days after notice to comply with any of its other covenants or agreements in the Indenture relating to the Notes; (iv) default by the Partnership or any of its Subsidiaries in the payment at the Stated Maturity, after the expiration of any applicable grace period, of principal of, premium, if any, or interest on any Debt then outstanding having a principal amount in excess of the greater of $25 million or 2% of total partners’ capital in the Partnership, or acceleration of any Debt having a principal amount in excess of the greater of such amounts so that it becomes due and payable prior to its Stated Maturity and such acceleration is not rescinded within 30 days after notice; (v) except as permitted by the Indenture, any Guarantee shall be held in any judicial proceeding to be null and void or shall cease to be in full force and effect or any Subsidiary Guarantor shall deny or disaffirm its obligations under the Indenture or its Guarantee; and (vi) certain events of bankruptcy, insolvency or reorganization with respect to the Issuer or, if and so long as the Notes are guaranteed by a Subsidiary Guarantor, such Subsidiary Guarantor. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare all the Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all Outstanding Notes shall become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or power. If and so long as the Trustee in good faith so determines, the Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interests. The Holders of not less than a majority in aggregate principal amount of the Notes then Outstanding by written notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, the principal of, or premium, if any, on, the Notes. The Partnership is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Partnership is required within 30 days after the occurrence of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default and certain additional information.

12. Trustee Dealings with Issuer. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates, as if it were not the Trustee.

13. No Recourse Against Others. The General Partner and its directors, officers, employees, incorporators, members and stockholders, as such, shall have no liability for any obligations of the Issuer or the Subsidiary Guarantors under the Notes, the Indenture or the Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

14. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

15. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

16. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP and corresponding ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP and corresponding ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

The Issuer shall furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:
