Preliminary Draft – Confidential Executive Summary Introduction ? Evercore Group L.L.C. (“Evercore”) is pleased to provide the materials herein to the Conflicts Committee of the Board of Directors (the “Conflicts Committee”) of Midcoast Holdings, L.L.C. (“Partnership GP”), the general partner of Midcoast Energy Partners, L.P. (“MEP”, “Midcoast” or the “Partnership”) regarding the proposed merger of the Partnership with a wholly owned subsidiary of Enbridge Energy Company, Inc., which in turn is a wholly owned subsidiary of Enbridge Inc. (“ENB”) (the “Proposed Transaction” or “Project Leather”) ? As part of the Proposed Transaction, ENB has proposed to acquire for cash each publicly-owned common unit of MEP for an amount equal to the greater of: (i) $7.70 per unit and (ii) the last price at which MEP common units trade during a regular trading session prior to the execution of definitive transaction documents (the “Proposed Consideration”) • Based on MEP’s closing unit price of $8.15 per unit as of January 20, 2017, the Proposed Consideration is $8.15 per unit - The Proposed Consideration represents a 0.0% premium to MEP’s closing unit price of $8.15 as of January 20, 2017 - The Proposed Consideration represents a 13.1% premium to MEP’s30-day volume weighted-average unit price of $7.20 as of January 20, 2017 ? The Proposed Transaction is subject to the negotiation and approval of the definitive merger agreement (the “Merger Agreement”) and approval by Partnership GP’s board of directors, the board of directors of the general partner of Enbridge Energy Partners, L.P. (“EEP”), the Conflicts Committee and a majority of MEP’s unitholders • As currently contemplated, MEP management expects the Board of Directors of Midcoast Holdings, L.L.C. to declare a quarterly cash distribution on all of its outstanding common and subordinated units for the quarter ending December 31, 2016 in conjunction with the Proposed Transaction • EEP’s subordinated units will be converted into common units one business day after such distribution payment in February 2017, which will result in EEP holding 53% of MEP’s common units and give EEP the ability to approve the Proposed Transaction by written consent    EVERCORE MIDCOAST ENERGY PARTNERS 1
