Spectra Energy Partners Announces Pricing of Public Offering of Common Units

HOUSTON — Spectra Energy Partners, LP (NYSE: SEP) (the “Partnership”) announced today that its public offering of 6,250,000 common units was priced at $32.87 per unit to the public. The Partnership expects the delivery of the units to occur on December 7, 2010. In addition, the underwriters have an overallotment option to purchase up to approximately 937,500 additional common units.

Assuming no exercise of the overallotment option, Spectra Energy Partners expects to receive net proceeds from the offering of approximately $200.7 million, after deducting the underwriting discount and estimated offering expenses payable by the Partnership, and including a capital contribution from its general partner to maintain its proportionate interest in the Partnership. The Partnership intends to use the net proceeds from this offering to repay an approximately $7.4 million loan owed to a subsidiary of Spectra Energy Corp (NYSE: SE) that it assumed in connection with the previously announced acquisition of an additional 24.5 percent interest in Gulfstream Natural Gas System, L.L.C. from Spectra Energy Corp (the “Acquisition”). The Partnership will use the remaining net proceeds from the offering to purchase qualifying investment grade securities, which will be assigned as collateral to secure a new term loan of an approximately equal principal amount. The proceeds of the term loan will be used to repay revolving borrowings under the Partnership’s revolving credit facility, which were incurred to fund a portion of the Acquisition.

Citi, BofA Merrill Lynch, Barclays Capital, J.P. Morgan, Morgan Stanley, and Wells Fargo Securities are acting act as joint book running managers for the offering. The offering is being made only by means of a prospectus supplement and accompanying base prospectus.
