Energy Transfer Equity, L.P. and Southern Union Company Announce the Commencement of Distribution of the Proxy Statement/Prospectus and a December 9, 2011 Special Meeting of Southern Union Stockholders

Energy Transfer Equity, L.P. (NYSE:ETE) and Southern Union Company (NYSE:SUG) today announced that Southern Union has commenced the distribution of the proxy statement/prospectus for the special meeting of Southern Union stockholders associated with ETE’s proposed acquisition of Southern Union.

The special meeting of Southern Union stockholders will be held at 11:00 a.m. Eastern Time on Friday, December 9, 2011 at the Metropolitan Club, One East 60th Street, New York, New York, 10022. The primary purpose of the meeting is to consider and take action on a proposal to approve the merger agreement and the transactions contemplated thereby.

Stockholders of record of shares of Southern Union common stock at the close of business on October 11, 2011, whether or not they attend the meeting, are entitled and urged to vote at this special meeting. If a stockholder cannot attend the meeting, they should still vote their shares by completing, signing, dating and returning the proxy card; using the toll-free telephone number shown on the proxy card; or using the internet website shown on the proxy card. Stockholders that hold Southern Union common stock through a bank or broker should follow the voting instructions provided by their bank or broker.

Approval of the merger agreement and the transactions contemplated thereby requires a simple majority of the outstanding shares of Southern Union common stock entitled to vote at the special meeting. Certain stockholders of Southern Union, who directly or indirectly own approximately 13.4% of Southern Union’s outstanding shares, have already agreed to vote in favor of the merger agreement and the transactions contemplated thereby (unless there is a change in the recommendation of the board of directors of Southern Union) and have also agreed to elect to receive ETE common units as consideration in the proposed merger rather than the cash consideration as described below. The board of directors of Southern Union has unanimously recommended the approval of the merger agreement and the transactions contemplated thereby.

Southern Union stockholders who have questions about the merger or other matters to be voted on at the special meeting, or would like additional copies of the proxy statement/prospectus or additional proxy cards, may contact Southern Union’s proxy solicitor at the address and telephone number listed below.

Terms and Benefits of the Transaction

Under the merger agreement, Southern Union stockholders may elect to receive, for each outstanding Southern Union share they hold and subject to the limits described below, either $44.25 in cash or 1.00 ETE common unit (and cash in lieu of fractional ETE common units). The cash consideration of $44.25 per Southern Union share represents a 56.6% premium over the closing price of Southern Union common stock as of June 15, 2011, the last trading day before the public announcement of ETE’s initial proposal to acquire the shares of Southern Union common stock, and a 53.1% premium to the 30-day average closing price of Southern Union common stock prior to such public announcement.

The election is subject to the following limits:

• The aggregate cash consideration will be capped at 60% of the aggregate merger consideration. Thus, if holders of more than 60% of the outstanding Southern Union shares make a cash election, the amount of cash per outstanding Southern Union share to be received by holders making a cash election will be reduced (pro rata across all outstanding Southern Union shares subject to a cash election), so that no more than 60% of the aggregate merger consideration is payable in cash and the remainder of the consideration in respect of outstanding Southern Union shares subject to a cash election will be payable in ETE common units at an exchange ratio of 1.00 ETE common unit per outstanding Southern Union share (and cash in lieu of fractional ETE common units).
• The aggregate ETE common unit consideration will be capped at 50% of the aggregate merger consideration. Thus, if holders of more than 50% of the outstanding Southern Union shares make or are deemed to have made an equity election, the number of ETE common units per outstanding Southern Union share to be received by holders making an equity election will be reduced (pro rata across all outstanding Southern Union shares subject to an equity election), so that no more than 50% of the aggregate merger consideration is payable in ETE common units and the remainder of the consideration in respect of outstanding Southern Union shares subject to an equity election will be payable in cash at $44.25 per outstanding Southern Union share.

Based on ETE’s current annualized cash distribution rate of $2.50 per ETE common unit, a Southern Union stockholder receiving ETE common units would initially receive approximately 317% more in quarterly cash distributions on an annualized basis after giving effect to the merger.
