Legal Notice Forward Looking Information This presentation includes certain forward looking statements and information (FLI) to provide potential investors, shareholders and unitholders of Enbridge Inc. (Enbridge or the Company), Enbridge Income Fund Holdings Inc. (ENF), Enbridge Energy Partners, L.P. (EEP), Enbridge Energy Management, LLC (EEQ) and Spectra Energy Partners, LP (SEP) with information about Enbridge, ENF, EEP, EEQ, SEP and their respective subsidiaries and affiliates, including management’s assessment of their future plans and operations, which FLI may not be appropriate for other purposes. FLI is typically identified by words such as “anticipate”, “expect”, “project”, “estimate”, “forecast”, “plan”, “intend”, “target”, “believe”, “likely” and similar words suggesting future outcomes or statements regarding an outlook. All statements other than statements of historical fact may be FLI. In particular, this presentation contains FLI pertaining to, but not limited to, information with respect to the following: 2018 and future year strategic priorities and guidance; expected EBITDA or expected adjusted EBITDA; expected DCF and DCF/share; expected future debt/EBITDA; future financing options; expectations on sources and uses of funds and sufficiency of financial resources; secured growth projects and future growth, development and expansion program and opportunities; expected benefits of asset dispositions; closing of announced dispositions, amalgamations and corporate simplification transactions, and the timing and impact thereof; future asset sales or other monetization transactions; sponsored vehicle strategy, including the simplification of the Company’s corporate structure and expected benefits thereof; distribution coverage; dividend and distribution growth and dividend and distribution payout expectations; expected impact of tax reform and FERC policy-related matters, including sponsored vehicle impacts; foreign exchange hedges; project execution, including capital costs, expected construction and in service dates and regulatory approvals; and system throughput, capacity, expansions and potential future capacity solutions. Although we believe that the FLI is reasonable based on the information available today and processes used to prepare it, such statements are not guarantees of future performance and you are cautioned against placing undue reliance on FLI. By its nature, FLI involves a variety of assumptions, which are based upon factors that may be difficult to predict and that may involve known and unknown risks and uncertainties and other factors which may cause actual results, levels of activity and achievements to differ materially from those expressed or implied by the FLI, including, but not limited to, the following: the expected supply of, demand for and prices of crude oil, natural gas, natural gas liquids and renewable energy; exchange rates; inflation; interest rates; availability and price of labour and construction materials; operational reliability and performance; customer and regulatory approvals; maintenance of support and regulatory approvals for projects; anticipated in-service dates; weather; governmental legislation; announced and potential disposition, amalgamation and corporate simplification transactions, and the timing and impact thereof; impact of capital project execution on the Company’s future cash flows; credit ratings; capital project funding; expected EBITDA or expected adjusted EBITDA; expected future cash flows and expected future DCF and DCF per share; estimated future dividends and distributions; financial strength and flexibility; debt and equity market conditions, including the ability to access capital markets on favourable terms or at all; cost of debt and equity capital; economic and competitive conditions; changes in tax laws and tax rates; and changes in trade agreements. We caution that the foregoing list of factors is not exhaustive. Additional information about these and other assumptions, risks and uncertainties can be found in applicable filings with Canadian and U.S. securities regulators (including the most recently filed Form 10-K and any subsequently filed Form 10-Q, as applicable). Due to the interdependencies and correlation of these factors, as well as other factors, the impact of any one assumption, risk or uncertainty on FLI cannot be determined with certainty. Except to the extent required by applicable law, we assume no obligation to publicly update or revise any FLI made in this presentation or otherwise, whether as a result of new information, future events or otherwise. All FLI in this presentation and all subsequent FLI, whether written or oral, attributable to Enbridge, ENF, EEP, EEQ or SEP, or persons acting on their behalf, are expressly qualified in its entirety by these cautionary statements. Non-GAAP Measures This presentation makes reference to non-GAAP measures, including adjusted earnings before interest, income taxes, depreciation and amortization (Adjusted EBITDA), ongoing EBITDA, distributable cash flow (DCF), ongoing DCF and DCF per share. Adjusted EBITDA represents EBITDA adjusted for unusual, non-recurring or non-operating factors on both a consolidated and segmented basis. Management uses adjusted EBITDA to set targets and to assess the performance. DCF is defined as cash flow provided by operating activities before changes in operating assets and liabilities (including changes in environmental liabilities) less distributions to non-controlling interests and redeemable non-controlling interests, preference share dividends and maintenance capital expenditures, and further adjusted for unusual, non-recurring or non-operating factors. Management also uses DCF to assess the performance and to set its dividend or distribution payout target. Management believes the presentation of these measures gives useful information to investors, shareholders and unitholders as they provide increased transparency and insight into the performance of Enbridge, ENF, EEP, EEQ and SEP. Reconciliations of forward looking non-GAAP financial measures to comparable GAAP measures are not available due to the challenges and impracticability with estimating some of the items, particularly with estimates for certain contingent liabilities, and estimating non-cash unrealized derivative fair value losses and gains and ineffectiveness on hedges which are subject to market variability and therefore a reconciliation is not available without unreasonable effort. These measures are not measures that have a standardized meaning prescribed by generally accepted accounting principles in the United States of America (U.S. GAAP) and may not be comparable with similar measures presented by other issuers. A reconciliation of non-GAAP measures to the most directly comparable GAAP measures is available on the applicable entity’s website. Additional information on non-GAAP measures may be found in the earnings news releases or additional information on the applicable entity’s website, www.sedar.com or www.sec.gov.

Q&A

Forward-Looking Statements

This communication includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are based on the beliefs and assumptions of Enbridge Inc. (“Enbridge”), Enbridge Energy Partners, L.P. (“EEP”), Enbridge Energy Management, L.L.C. (“EEQ”), Spectra Energy Partners, LP (“SEP”), and Enbridge Income Fund Holdings Inc. (“ENF” and, together with EEP, EEQ and SEP, the “Sponsored Vehicles”). These forward-looking statements are identified by terms and phrases such as: anticipate, believe, intend, estimate, expect, continue, should, could, may, plan, project, predict, will, potential, forecast and similar expressions and include, but are not limited to, statements regarding the expected closing, consummation, completion, timing and benefits of the acquisitions of the Sponsored Vehicles (collectively, the “Proposed Transactions”), the expected synergies and equityholder value to result from the combined companies, the expected levels of cash distributions or dividends by the Sponsored Vehicles to their respective shareholders or unitholders, the expected levels of dividends by Enbridge to its shareholders, the expected financial results of Enbridge and its Sponsored Vehicles and their respective affiliates, and the future credit ratings, financial condition and business strategy of Enbridge, its Sponsored Vehicles and their respective affiliates.

Although Enbridge and its Sponsored Vehicles believe these forward-looking statements are reasonable based on the information available on the date such statements are made and processes used to prepare the information, such statements are not guarantees of future performance and readers are cautioned against placing undue reliance on forward-looking statements. By their nature, these statements involve a variety of assumptions, known and unknown risks and uncertainties and other factors, which may cause actual results, levels of activity and achievements to differ materially from those expressed or implied by such statements. Material assumptions include assumptions about the following: the expected supply of and demand for crude oil, natural gas, natural gas liquids (“NGL”) and renewable energy; prices of crude oil, natural gas, NGL and renewable energy; exchange rates; inflation; interest rates; availability and price of labor and construction materials; operational reliability; customer and regulatory approvals; maintenance of support and regulatory approvals for projects; anticipated in-service dates; weather; the timing and closing of dispositions; the realization of anticipated benefits and synergies of the Proposed Transactions; governmental legislation; acquisitions and the timing thereof; the success of integration plans; impact of capital project execution on future cash flows; credit ratings; capital project funding; expected earnings; expected future cash flows; and estimated future dividends. Assumptions regarding the expected supply of and demand for crude oil, natural gas, NGL and renewable energy, and the prices of these commodities, are material to and underlie all forward-looking statements, as they may impact current and future levels of demand for Enbridge’s and its Sponsored Vehicles’ services. Similarly, exchange rates, inflation and interest rates impact the economies and business environments and may impact levels of demand for Enbridge’s and its Sponsored Vehicles’ services and cost of inputs, and are therefore inherent in all forward-looking statements. Due to the interdependencies and correlation of these macroeconomic factors, the impact of any one assumption on a forward-looking statement cannot be determined with certainty, particularly with respect to the impact of the Proposed Transactions, expected earnings and cash flow or estimated future dividends.

Forward-looking statements involve risks and uncertainties that may cause actual results to be materially different from the results predicted. There are a number of important factors that could cause actual results to differ materially from those indicated in any forward-looking statement including, but not limited to: the risk that the Proposed Transactions do not occur; negative effects from the pendency of the Proposed Transactions; the ability to realize expected cost savings and benefits from the Proposed Transactions; the timing to consummate the Proposed Transactions; whether the Sponsored Vehicles or Enbridge will produce sufficient cash flows to provide the level of cash distributions they expect with respect to their respective units or shares; outcomes of litigation and regulatory investigations, proceedings or inquiries; operating performance of Enbridge and its Sponsored Vehicles; regulatory parameters regarding Enbridge and its Sponsored Vehicles; other Enbridge dispositions; project approval and support; renewals of rights of way; weather, economic and competitive conditions; public opinion; changes in tax laws and tax rates; changes in trade agreements, exchange rates, interest rates, commodity prices, political decisions and supply of and demand for commodities; and any other risks and uncertainties discussed herein or in Enbridge’s or its Sponsored Vehicles’ other filings with Canadian and United States securities regulators. All forward-looking statements in this communication are made as of the date hereof and, except to the extent required by applicable law, neither Enbridge nor any of the Sponsored Vehicles assume any obligation to publicly update or revise any forward-looking statements made in this communication or otherwise, whether as a result of new information, future events or otherwise. All subsequent forward-looking statements, whether written or oral, attributable to Enbridge, its Sponsored Vehicles or persons acting on their behalf, are expressly qualified in their entirety by these cautionary statements. The factors described above, as well as additional factors that could affect Enbridge’s or any of its Sponsored Vehicles’ respective forward-looking statements, are described under the headings “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Information” in Enbridge’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, which was filed with the U.S. Securities and Exchange Commission (“SEC”) and Canadian securities regulators on February 16, 2018, each of EEP’s, EEQ’s and SEP’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, which were filed with the SEC on February 16, 2018, ENF’s Management’s Discussion and Analysis for the year ended December 31, 2017, which was filed with Canadian securities regulators on February 16, 2018, and in Enbridge’s and its Sponsored Vehicles’ respective other filings made with the SEC and Canadian securities regulators, which are available via the SEC’s website at http://www.sec.gov and at http://www.sedar.com, as applicable.
