SOUTHWESTERN ENERGY ANNOUNCES AGREEMENT TO PURCHASE
RIGS FOR FAYETTEVILLE SHALE PLAY

Houston, Texas - July 6, 2005...Southwestern Energy Company (NYSE: SWN) today announced that it has entered into a sales agreement with a private company to fabricate five new land drilling rigs plus associated equipment for an aggregate purchase price of approximately $37.7 million. The rigs will be capable of drilling both vertical and horizontal wells in the company's Fayetteville Shale play.

Delivery of the first rig is expected to occur in November 2005, with one additional rig delivered each month thereafter. The 2005 rig commitment is in addition to the company's previous capital spending plan of up to approximately $353 million.

This agreement improves our ability to meet our development objectives for our Fayetteville Shale play in the most cost efficient manner," stated Harold M. Korell, President and Chief Executive Officer of Southwestern Energy. "These new rigs have design features that are optimal for faster drilling and mobilization in our Fayetteville Shale play, which will allow us to accelerate the pace of development of the Fayetteville Shale play in 2006."
