Spectra Energy Partners to Acquire 50 Percent of Spectra Energy Corp’s 77.53 Percent

Interest in Maritimes & Northeast Pipeline, L.L.C. (M&N US)

— Enhances Spectra Energy Partners’ profile of steady, fee-based cash flows

— Expands Spectra Energy Partners’ reach into the northeastern United States

HOUSTON — Spectra Energy Partners, LP (NYSE: SEP) today announced an agreement to acquire a 38.76 percent interest in Maritimes & Northeast Pipeline, L.L.C. (M&N US) from Spectra Energy Corp (NYSE: SE) for approximately $319 million in cash and approximately $56 million in newly issued partnership units. M&N US has debt outstanding of $439 million, 38.76 percent of which is $170 million.

M&N US owns a FERC-regulated, 338-mile mainline interstate natural gas transportation system in the U.S., which extends from the border of Canada near Baileyville, Maine, to northeastern Massachusetts and has market delivery capability of approximately 0.8 billion cubic feet per day (Bcf/day) of natural gas. The pipeline’s location and key interconnects with Spectra Energy’s transmission system link regional natural gas supplies to the Northeast U.S. and Atlantic Canadian markets. M&N US’s stable cash flows are backed by an average contract life of approximately 19 years and over 90 percent fee-based revenues.

“We are pleased to have a stake in the Maritimes & Northeast Pipeline which further enhances Spectra Energy Partners’ profile of steady, fee-based cash flows and broadens the partnership’s market reach into the Northeast, building on its significant Southeast U.S. position,” said Julie A. Dill, president and chief executive officer. “This acquisition is accretive to distributable cash and is consistent with our strategy of delivering value to our unitholders,” continued Dill.

SEP’s estimated 2013 incremental earnings before interest, taxes, depreciation and amortization (EBITDA) and cash available for distribution (CAD) from its 38.76 percent interest in M&N US assets is projected to be approximately $50 million and $31 million, respectively. The company plans to utilize short-term borrowings to fund its cash consideration. SEP expects long-term financing for the transaction to be a combination of debt and equity. The transaction is expected to close on October 31, 2012, subject to customary closing conditions.

The terms of the transaction were unanimously approved by the Board of Directors of the general partner of Spectra Energy Partners’ general partner, based on the unanimous approval and recommendation of the Board’s conflicts committee, which is comprised entirely of independent directors. The conflicts committee engaged Evercore Partners to act as its financial advisor and Andrews Kurth LLP to act as its legal advisor.

Reconciliation of Non-GAAP Financial Measures

This press release includes a discussion of earnings before interest, taxes, depreciation and amortization (EBITDA) and cash available for distribution (CAD) which are non-GAAP (Generally Accepted Accounting Principles) financial measures as defined under the rules of the SEC. This press release is accompanied by a reconciliation of these non-GAAP financial measures to the nearest GAAP financial measure, Net Income. Management uses these financial measures because they are an accepted financial indicator used by investors to compare company performance. In addition, management believes that these measures provide investors an enhanced perspective of the projected operating performance of the business’ assets. EBITDA and CAD are not presented as an alternative to net income and should not be considered in isolation or as substitutes for measures of performance prepared in accordance with United States GAAP.
