Sepctra Energy ENBRIDGE



To our stockholders:

By now you should have received proxy materials regarding the proposed merger of Spectra Energy Corp and Enbridge Inc.—a transaction that will create the largest energy infrastructure company in North America.

Our Board of Directors believes the proposed merger will create value for all Spectra Energy stockholders and unanimously recommends that you vote FOR the transaction. The combined company will have what we believe is the finest platform for serving customers with excellence in every region of North America. We believe it will provide investors with superior stockholder return opportunities, including an anticipated annualized dividend increase of 15 percent in 2017 post-closing, with annual 10 to 12 percent dividend growth thereafter through 2024.

These benefits can only be realized, however, with your vote FOR the Spectra

Energy/Enbridge merger. I encourage you to review the previously provided proxy materials. Then please take a moment to cast your vote today—by telephone or internet or by signing, dating and returning the enclosed proxy card.

Thank you,

Gregory L.Ebel

President and Chief Executive Officer


Questions and Answers:

Why do I need to vote?

Your vote is very important. The merger cannot be completed without the approval of the Merger Proposal by Spectra Energy stockholders, which requires the affirmative vote of the holders of a majority of the outstanding shares of Spectra Energy common stock entitled to vote at the special meeting.

What am I being asked to vote on?

You are being asked to vote on the following proposals:

Merger Proposal: to adopt the merger agreement. Spectra Energy will survive the merger as a direct, wholly owned subsidiary of Enbridge; and

Advisory Compensation Proposal: to approve, on an advisory (non-binding) basis, certain specified compensation that will or may be paid by Spectra Energy to its named executive officers, which is based on or otherwise relates to the merger.

The approval of the Merger Proposal by the stockholders of Spectra Energy is a condition to the obligations of Spectra Energy and Enbridge to complete the merger. The approval of the Advisory Compensation Proposal is not a condition to the obligations of Spectra Energy or Enbridge to complete the merger and will not be binding on Spectra Energy or Enbridge following the merger.

How does the Spectra Energy Board of Directors recommend that I vote?

The Spectra Energy Board of Directors unanimously recommends that you vote FOR the Merger Proposal and Advisory Compensation Proposal. Combining Spectra Energy and Enbridge would create North America’s premier energy infrastructure company, with an enterprise value of US$127 billion (C$165 billion).(1) The transaction would result in increased scale, asset diversity, financial flexibility and an industry-leading secured project portfolio and development project inventory.

What happens next?

The transaction is expected to close in the first quarter of 2017, subject to the receipt of both companies’ stockholder approvals, along with certain regulatory and government approvals, including compliance with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and approval under Canada Competition Act, and the satisfaction of other customary closing conditions.

What do I need to do now?

Because the Merger Proposal requires the affirmative vote of the holders of a majority of the outstanding shares of Spectra Energy common stock entitled to vote at the special meeting, we urge all stockholders to consider and promptly vote on the Merger Proposal.

Your vote is important. Please vote today—by telephone or internet, or by signing, dating and returning the enclosed proxy card.
