XTO Energy Acquires Acreage from Total E&P USA for $300 Million

XTO Energy has agreed to purchase producing properties from Total E&P USA, Inc. with an effective date of January 1, 2006 for $300 million. These properties further expand operations in XTO Energy's core Eastern Region. XTO Energy's internal engineers estimate the proved reserves to be 120 billion cubic feet of gas equivalent (Bcfe), of which 60% are proved developed and 95% are attributable to natural gas. XTO estimates its development costs for the proved undeveloped reserves at $1.20 - $1.40 per thousand cubic feet (Mcf). The acquisitions will initially add production of about 15 million cubic feet of natural gas per day (MMcf/d).

Approximately 75% of the acquired reserves are located in the Company's Sabine Uplift region of East Texas. These premium properties expand XTO's presence in the Carthage Field and establish a new position in the Bethany Field. The remaining reserves are located in the highly prolific Maben Field of Mississippi which is characterized by its high per-well production rates and reserves at a premium natural gas price.

"We continue to acquire great producing properties, from the Majors, which build opportunities for the future," stated Keith A. Hutton, President. "The properties in the Sabine Uplift complement our ongoing development program with long-lived production and additional inventory. In Mississippi, the Maben Field offers potential to increase productivity through different stimulation techniques, uphole recompletions and new horizontal and vertical well targets. As always, our team will remain focused on pursuing bolt-on acquisitions throughout the year."

The transaction is scheduled to close on or before February 28, 2006. The final closing price will reflect a net revenue adjustment from the effective date, typical closing and post-closing adjustments.
