                                OMNIBUS AGREEMENT

     This OMNIBUS AGREEMENT (this "Agreement"), dated as of October 17, 2002, is
entered into among Enbridge Energy Company, Inc. (f/k/a Lakehead Pipe Line
Company, Inc.), a Delaware corporation ("EECI"), Enbridge Energy Partners, L.P.
(f/k/a Lakehead Pipe Line Partners, L.P.), a Delaware limited partnership (the
"MLP") and Enbridge Pipelines Inc. (f/k/a Interprovincial Pipe Line Inc.), a
Canadian corporation ("ENBRIDGE").

                                    RECITALS

     WHEREAS, the MLP, EECI and Enbridge are parties to that certain
Distribution Support Agreement dated as of December 27, 1991 (the "DISTRIBUTION
SUPPORT AGREEMENT") pursuant to which such parties entered into certain
covenants and agreements with each other in connection with the formation of the
MLP; and

     WHEREAS, the parties desire to amend and restate the Distribution Support
Agreement as set forth herein to make changes desired by the parties and
permitted under SECTION 6.6 of the Distribution Support Agreement.

     NOW, THEREFORE, for and in consideration of the mutual covenants contained
in this Agreement, the parties hereto hereby agree to amend and restate the
Distribution Support Agreement as follows:

                                    ARTICLE I
                                   DEFINITION

     SECTION 1.1. DEFINITION OF "AFFILIATE". As used in this Agreement,
"Affiliate" means, with respect to any person, any other person that directly or
indirectly controls, is controlled by or is under common control with, the
person in question. As used herein, the term "control" means the possession,
directly or indirectly, of the power to direct or cause the direction of the
management and policies of a person, whether through ownership of voting
securities, by contract or otherwise.

                                   ARTICLE II
                                    TRADEMARK

     SECTION 2.1. TRADEMARK. Enbridge hereby grants to the MLP and its
Affiliates, a worldwide non-exclusive royalty-free right and license, for so
long as an Affiliate of Enbridge serves as general partner of the MLP, to use
(i) the blue oil drop symbol which has been used in the past by Enbridge and
EECI and (ii) the Enbridge Energy Spiral (the blue oil drop symbol and the
Enbridge Energy Spiral being collectively referred to as the "Symbols") and
related goodwill. The MLP (i) agrees to maintain the quality of services
provided in connection with the Symbols to a level at least as high as the
quality standards of Enbridge in its use of the Symbols and (ii) acknowledges
that Enbridge is the owner of the Symbols with full right, title and interest
therein and that all use by any of them of the Symbols shall inure to the
benefit of Enbridge.

                                   ARTICLE III
                              OPERATIONAL SERVICES

     SECTION 3.1. PROVISION OF TRANSITION SERVICES. To the extent that Enbridge
is providing services to Enbridge Energy Management L.L.C. ("MANAGEMENT") or one
of its Affiliates under the Operational Services Agreement dated as of even date
herewith between Enbridge, EECI and Management (the "OPERATIONAL SERVICES
AGREEMENT") as of the effective date of (i) withdrawal by EECI as the general
partner of the MLP, (ii) removal of EECI as general partner of the MLP under
circumstances where "cause" exists or (iii) transfer of the capital stock of
EECI to any Person that is not an Affiliate of Enbridge, then Enbridge shall be
obligated to provide such services on substantially the same terms and
conditions as provided in the Operational Services Agreement, to the MLP for
twelve months following such effective date, but shall have no such obligation
under the Operational Services Agreement thereafter.

     SECTION 3.2. INDEMNITY. The obligations of Enbridge under Article 5
(Liability and Indemnification) of the Operational Services Agreement shall
extend to the MLP and its subsidiaries upon the same terms as provided in the
Operational Services Agreement with respect to Management and EECI.

                                   ARTICLE IV
                                CHANGE IN CONTROL

     SECTION 4.1. ASSIGNMENT UPON CHANGE OF CONTROL. In the event of a Change of
Control of EECI, Enbridge may assign its obligations under this Agreement to the
controlling person of EECI if, after taking into account the Change of Control
transaction, the unsecured long-term debt credit rating of such controlling
person as assigned by a nationally recognized statistical rating organization
would be, after giving effect to such Change of Control transaction, at least
equal to the unsecured long-term debt credit rating of Enbridge as assigned by a
nationally recognized statistical rating organization immediately before such
Change of Control transaction.

     SECTION 4.2. DEFINITION OF CHANGE OF CONTROL. A "CHANGE OF CONTROL" shall
be deemed to have occurred at such time as Enbridge shall no longer own,
directly or indirectly, at least 50% of the outstanding capital stock of EECI.

                                    ARTICLE V
                             BUSINESS OPPORTUNITIES

     SECTION 5.1. PROHIBITED ACTIVITIES OF EECI. EECI agrees that its sole
business will be to act as general partner of the MLP, to manage certain
subsidiaries and to undertake ancillary activities. EECI shall not permit any
subsidiary to engage in or acquire any business that is in direct material
competition with the business of the MLP or Enbridge Energy, Limited Partnership
(the "OPERATING PARTNERSHIP") conducted immediately following December 27, 1991
(the "CLOSING DATE").

     SECTION 5.2. PROHIBITED ACTIVITIES OF ENBRIDGE AND ITS OTHER SUBSIDIARIES.
No provision of this Agreement shall restrict the ability of Enbridge and its
Affiliates other than EECI to engage in any business. However, so long as an
Affiliate of Enbridge is the general

                                        2
<Page>

partner of the MLP, Enbridge and its subsidiaries other than EECI ("OTHER
SUBSIDIARIES") shall not engage in or acquire any business that is in direct
material competition with the current business of the MLP (which term, for
purposes of this Section, includes the Operating Partnership); PROVIDED,
HOWEVER, that

          (i)   Enbridge and its other subsidiaries shall not be restricted from
     continuing to engage in businesses, including the normal development of
     those businesses in which they were engaged as of the Closing Date, which
     then were or may in the future be in competition with the MLP, including
     the reversal of Enbridge's line from Sarnia, Ontario to Montreal, Quebec to
     transport crude oil from Montreal to Sarnia;

          (ii)  such restriction shall be limited geographically only to those
     routes and products in respect of which the MLP, as of the Closing Date,
     provides transportation (so that, for example, Enbridge and its other
     subsidiaries would be permitted to acquire a crude oil pipeline business in
     which transportation is made over routes or involving products not served
     by the MLP at the Closing Date);

          (iii) Enbridge and its other subsidiaries shall not be prohibited from
     acquiring any competitive business as part of a larger acquisition so long
     as the majority of the value of the business or assets acquired, in
     Enbridge's reasonable judgment, is not attributable to such competitive
     business; and

          (iv)  Enbridge and its other subsidiaries shall not be prohibited from
     acquiring any competitive business if such business is first offered for
     acquisition to the MLP and the MLP fails to approve, after submission to
     Unitholder (as defined in the MLP's Third Amended and Restated Partnership
     Agreement dated as of even date herewith) vote, the making of such
     acquisition.

The approval of the holders of a majority of the outstanding Units in the MLP
(excluding for this purpose any Units held by EECI or any of its Affiliates) is
required for the MLP to exercise its right to accept such an offer.

     Except as specified above, Enbridge and its other subsidiaries are not
restricted by this Agreement from engaging in businesses which may be in
competition with the MLP

                                   ARTICLE VI
                                  MISCELLANEOUS

     SECTION 6.1. BENEFIT OF AGREEMENT. The covenants and agreements contained
