Energy Transfer Equity, L.P.

and Southern Union Company

today announced that they have filed with the Missouri Public Service Commission (the “Commission”) a Stipulation and Agreement (the “Stipulation”) among Southern Union, ETE and the Commission Staff. Pursuant to the Stipulation, the parties recommend that the Commission issue an order finding that, subject to the conditions therein, the merger of Sigma Acquisition Corporation, a wholly-owned subsidiary of ETE, with and into Southern Union is not detrimental to the public interest and authorizing the undertaking of such merger and related transactions. Southern Union will survive the merger as a wholly-owned subsidiary of ETE. The Office of Public Counsel has indicated that it does not oppose the Stipulation. Southern Union and ETE have requested that the Commission consider the Stipulation expeditiously. Southern Union and ETE further announced that all of the documents necessary for Southern Union stockholders to make a merger consideration election in connection with the companies' proposed merger are being mailed on February 17, 2012 to Southern Union stockholders of record as of February 10, 2012. The companies also announced that the election deadline for Southern Union stockholders to make merger consideration elections is currently expected to be 5:00 p.m., Eastern Time, on March 19, 2012 (or such other later date as ETE and Southern Union shall agree).
