Plains All American Pipeline, L.P. Prices Public Offering of Common Units

Plains All American Pipeline, L.P. announced that it has priced an underwritten public offering of 5,000,000 of its common units representing limited partner interests at $80.03 per common unit. The offering is expected to close on March 9, 2012. The Partnership has also granted the underwriters a 30-day option to purchase up to 750,000 additional common units to cover over-allotments, if any. The Partnership intends to use the net proceeds of the offering, including the proceeds from any exercise of the over-allotment option, to fund a portion of the proposed acquisition (the BP NGL Acquisition) of BP Canada Energy Company, a wholly owned subsidiary of BP Corporation North America, Inc. Pending the application of the net proceeds to fund the BP NGL Acquisition, the Partnership intends to repay all borrowings outstanding under the PAA credit facilities and use the balance for general partnership purposes. If the BP NGL Acquisition is not consummated for any reason, the Partnership will use the net proceeds for general partnership purposes, including future acquisitions and capital program expenditures. Barclays Capital, BofA Merrill Lynch, Citigroup, J.P. Morgan, UBS Investment Bank and Wells Fargo Securities are joint book-running managers of the offering.
