Exxon Mobil Corporation and XTO Energy Inc. have reported an all-stock transaction valued at $41 billion. The agreement, which is subject to XTO stockholder approval and regulatory clearance, will enhance ExxonMobil's position in the development of unconventional natural gas and oil resources.

Under the terms of the agreement, approved by the boards of directors of both companies, ExxonMobil has agreed to issue 0.7098 common shares for each common share of XTO. This represents a 25 percent premium to XTO stockholders. The transaction value includes $10 billion of existing XTO debt and is based on the closing share prices of ExxonMobil and XTO on December 11, 2009.

'We are pleased that ExxonMobil and XTO have reached this agreement,' said Rex W. Tillerson, chairman and chief executive officer of Exxon Mobil Corporation.

'XTO is a leading U.S. unconventional natural gas producer, with an outstanding resource base, strong technical expertise and highly skilled employees. XTO's strengths, together with ExxonMobil's advanced R&D and operational capabilities, global scale and financial capacity, should enable development of additional supplies of unconventional oil and gas resources, benefiting consumers both here in the United States and around the world.'

Tillerson said the agreement is good news for the United States economy and energy security, as it will enhance opportunities for job creation and investment in the production of America's own clean-burning natural gas resources.

XTO's resource base is the equivalent of 45 trillion cubic feet of gas and includes shale gas, tight gas, coal bed methane and shale oil. These will complement ExxonMobil's holdings in the United States, Canada, Germany, Poland, Hungary and Argentina.

Following the transaction closing, ExxonMobil intends to establish a new upstream organization to manage global development and production of unconventional resources, enabling the rapid development and deployment of technologies and operating practices to increase production and maximize resource value. The new organization will be located in Fort Worth, Texas, in XTO's current offices.

Bob R. Simpson, chairman and founder of XTO, said that over the company's 23-year history, XTO has developed technical expertise and has assembled a substantial, high-quality and diverse resource base in producing basins across the United States.
