June 11, 2008HAMILTON, BERMUDA–(Marketwire – June 11, 2008) – Teekay Offshore Partners L.P. (Teekay Offshore or the Partnership) (NYSE:TOO) announced today that it plans to offer 7,000,000 common units representing limited partner interests in a public offering. Teekay Offshore expects to grant the underwriters a 30-day option to purchase an additional 1,050,000 common units to cover over-allotments, if any. In addition and concurrently with the closing of the public offering, Teekay Corporation (Teekay) has agreed that it will purchase directly from Teekay Offshore in a private placement an aggregate of $65.0 million worth of common units at the public offering price. The Partnership expects to use the net proceeds from the public offering and the concurrent private placement to purchase an additional 25.0% interest in Teekay Offshore Operating L.P. (OPCO), a Marshall Islands limited partnership, from Teekay, for $205.0 million. The Partnership will use any remaining net proceeds to partially repay amounts it borrowed from OPCO to facilitate the purchase of three vessels in 2007. OPCO will apply any net proceeds it receives from Teekay Offshore towards the purchase of two 2008-built Aframax lightering tankers or the repayment of debt. Teekay Offshore Partners L.P. is a publicly-traded master limited partnership formed by Teekay (NYSE:TK), and is an international provider of marine transportation and storage services to the offshore oil industry. Teekay Offshore currently owns a 26% interest in and controls OPCO with a fleet of 34 shuttle tankers (nine of which are chartered-in), four floating storage and offtake (FSO) units and nine conventional crude oil Aframax tankers. The Partnership also has direct ownership interests in two shuttle tanker and one FSO. Teekay Offshore’s common units trade on the New York Stock Exchange under the symbol “TOO”. After the offering and the concurrent private placement, Teekay will own approximately a 50% interest in Teekay Offshore, including common units, subordinated units and its general partner interest. This ownership interest will be reduced to approximately 49% if the underwriters exercise their over-allotment option in full. Subsequent to the offering, Teekay Offshore expects to own 51% of OPCO.
