Item 8.01

Other Events

On May 2, 2006, we announced that our Texas Gas Service division received approval to implement new rates in two of its service areas. The implementation will affect 56,500 customers and will increase revenues by $2.5 million. The new rates went into effect on April 28, 2006.

The first of the two areas consists of 11 cities between Abilene and Fort Worth. The request was approved for $865,000, or a 4.2 percent increase, in revenue and return on equity of 10.85 percent. We also received approval to increase rates in our service area in south Jefferson County, which includes the city of Port Arthur. These cities agreed to a $1.6 million, or 9 percent, increase in revenue and return on equity of 11 percent.

Texas Gas Service also has a rate case pending approval in the Rio Grande Valley.
