Federal Court Dismisses Claims by Tiverton Bay Street Residents.

HOUSTON -- On November 3, 2006, Chief Judge Ernest C. Torres of the Federal District Court in Providence, R.I., dismissed four of the claims brought against Southern Union Company (NYSE:SUG) by the residents of the Bay Street Area of Tiverton, R. I. The residents claim that Fall River Gas Company, which was acquired by Southern Union in 2000, was responsible for contamination of their properties in the 1930s and 1940s, decades before their properties were developed.

The Federal District Court dismissed plaintiff's claims for gross negligence, infliction of emotional distress, violation of Rhode Island's Hazardous Waste Management Act and private nuisance, finding them defective as a matter of law. The court sustained the remaining three claims at this initial stage of the proceeding.

Eric D. Herschmann, Southern Union's senior executive vice president, commented, "The company is gratified that the court has dismissed the four claims. The company believes that the remaining claims also lack merit, and it will continue its vigorous defense of those claims."
