MISCELLANEOUS

Section 5.01          Use of Proceeds.  Enbridge Partners shall use the net proceeds it receives from the sale of Class A Common Units (together with the General Partner’s related 2% capital contribution) to repay a portion of its outstanding commercial paper and credit facility borrowings and to finance a portion of its capital expansion program relating to the expansion of its core liquids and natural gas systems.  A portion of such net proceeds may be invested in short term investment grade securities pending the use of such net proceeds for Enbridge Partners’ capital expansion program.

Section 5.04          Waivers; Remedies; Amendments.

(a)           No Waiver; Remedies Cumulative.  No failure or delay on the part of any party in exercising any right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power, or remedy preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

(b)           Amendments and Modifications.  No amendment, waiver, consent, modification or termination of any provision of this Agreement shall be effective unless signed by each of the parties hereto affected by such amendment, waiver, consent, modification or termination.  Any amendment, supplement or modification of or to any provision of this Agreement, any waiver of any provision of this Agreement, and any consent to any departure by any party hereto from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific purpose for which made or given.  Except where notice is specifically required by this Agreement, no notice to or demand on any party hereto in any case shall entitle any party hereto to any other or further notice or demand in similar or other circumstances.
