Bernstein Liebhard Announces Investigation of Southern Union Company

June 16, 2011

Bernstein Liebhard LLP is investigating whether the Board of Directors of Southern Union Company (“Southern Union” or the “Company”) (NYSE: SUG) breached its fiduciary duty to its shareholders in agreeing to sell Southern Union to Energy Transfer Equity, L.P. (“ETE”).

Under the terms of the agreement, Southern Union shareholders will exchange their common shares for newly issued Series B Units of ETE with a value of $33.00 per share. The investigation is focused on the potential unfairness of the price to Southern Union shareholders and the process by which the Southern Union Board of Directors considered and approved the transaction.

If you are interested in discussing your rights as a Southern Union shareholder and/or have information relating to the matter, please contact U. Seth Ottensoser at (877) 779-1414 or Ottensoser@bernlieb.com.
