SOUTHERN UNION ANNOUNCES

SETTLEMENT OF LITIGATION

HOUSTON, February 1, 2007— Southern Union Company (NYSE: SUG) today announced the settlement of litigation brought by Citrus Trading Corp. against Spectra Energy LNG Sales, Inc. (formerly known as Duke Energy LNG Sales, Inc.) for a cash payment to Citrus Trading of $100 million.

Southern Union owns a 50 percent equity interest in Citrus Corp., which owns both Citrus Trading and Florida Gas Transmission Company. Through its subsidiary, CCE Holdings, LLC, Southern Union is contractually obligated to share a portion of its proceeds with the Enron bankruptcy estate.

The litigation, before the Honorable Lynn N. Hughes in the United States District Court for the Southern District of Texas, related to Spectra’s 2003 termination of natural gas purchase and sale arrangements with Citrus Trading.

“We are delighted to have reached an amicable resolution of this matter. We have tremendous respect for Spectra and look forward to strengthening our relationship,” said Eric D. Herschmann, senior executive vice president of Southern Union, who served as lead negotiator for Citrus Trading.

Herschmann and Daniel W. Bishop, II of Bishop London Brophy & Dodds, P.C. served as lead trial counsel for Citrus Trading.
