Press Release
Energy Transfer Equity Believes its Agreement to Acquire Southern Union is Superior to the Highly Conditional Proposal from Williams

DALLAS, Jun 23, 2011 (BUSINESS WIRE) --

Energy Transfer Equity L.P. (NYSE:ETE) notes that Williams (NYSE:WMB) floated a non-binding, conditional proposal to acquire Southern Union Company (NYSE:SUG) in a fully-taxable transaction to SUG shareholders. ETE believes its binding agreement provides superior value to SUG shareholders as compared to the Williams proposal.

From a price standpoint, ETE's transaction is not a $33.00 per share offer as Williams contends. Rather, the ETE transaction is a tax deferred structure that provides SUG shareholders significant potential upside through at least an 8.25% annualized yield (paid quarterly) as well as the ability for SUG shareholders, at their option, to convert into ETE common units at a fixed exchange ratio of 0.770x after the first anniversary of closing. Tellingly, prior to withdrawing equity research coverage on ETE today, Williams' own financial advisors, Barclays Capital and Citi, had stated target prices of $53.00 and $52.50 respectively, representing an additional 15+% upside from ETE's closing unit price of $45.57 on June 23, 2011.

Furthermore, the Williams proposal does not have committed financing, may have negative ratings consequences for SUG, is subject to completion of due diligence and may have material anti-trust regulatory challenges.

In contrast, ETE's agreement with SUG has been unanimously approved by the Boards of Directors of both companies, is not subject to any financing conditionality or ETE unitholder approval and is not expected to result in any anti-trust issues. In addition, ETE's transaction has been reviewed by all the credit rating agencies and is expected to have no ratings impact on the current ratings of SUG.
