ExxonMobil-XTO Agreement
ExxonMobil Background Information

 
Agreement
 
·
The agreement brings together two highly complementary organizations whose combined strengths will deliver strong shareholder value and open new opportunities for the production of clean-burning natural gas.
 
·
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 have no current plans to dispose of any assets. However, we have an ongoing asset management process by which we continually evaluate all assets.
 
·
Completion of the transaction is expected in the second quarter of 2010.
 
·
The transaction is structured as a tax-free exchange of shares.
 
·
We expect the agreement to be accretive to production growth and cash flow.
 
·
Depending on the market price for gas, it is not likely to be accretive to near-term earnings per share and may be dilutive.
 
·
Legally, the agreement is structured as a merger.
 
 
Natural Gas
 
·
This agreement is good news for the United States as it will help produce more of America’s own clean-burning natural gas, which brings with it innovation, technology, investment and jobs.
 
·
ExxonMobil’s Energy Outlook indicates that gas will grow more rapidly than any other major energy source given its availability and relatively low carbon profile.
 
·
We believe gas is the fuel of choice for power generation where it will increasingly replace coal. Natural gas produces fewer greenhouse gas emissions than other electrical-generation fuels, such as coal.
 
·
Technological advances have allowed industry to define 80 to 100 years of natural gas resource in the U.S. at current production rates.
 
 
Evaluating Opportunities
 
·
The agreement has resulted from an ongoing, disciplined evaluation of timely investment opportunities to create value for shareholders. It is consistent with ExxonMobil’s business model, which is focused on sustainable, long-term value creation.
 
·
ExxonMobil’s primary focus is on maximizing value for our shareholders.  We are interested in the best oil and gas opportunities.
 
·
All of our projects are evaluated on their own merits. This deal does not preclude any other opportunities.
 
·
We are constantly monitoring potential opportunities that can add value for shareholders.
 
·
We believe we are well positioned should further good opportunities present themselves.

Credit Rating / Debt
 
·
While ratings decisions are ultimately made by rating agencies, our approach to this transaction is consistent with financial principles underlying ExxonMobil’s long-standing AAA rating and superior access to financial markets.
 
·
As an all-share transaction, there will be no new acquisition debt or use of cash associated with the agreement. ExxonMobil’s consolidated balance sheet will reflect the debt currently on XTO’s balance sheet but it will not make an appreciable change in ExxonMobil’s all-in leverage ratio, which is a key metric for the rating agencies.
 
·
Regarding potential debt repayment, we will do a complete analysis of our options using our long-standing principles of focusing on shareholder value and maintaining a conservative capital structure.
 

Share Repurchase Program
 
·
Investing wisely in attractive energy opportunities is our first priority.
 
·
When we have paid our expenses, paid taxes to governments and invested in all of the projects that meet our investment criteria, we pay a dividend and where appropriate, return cash to our shareholders through buybacks so that they can redeploy it in the economy.
 
·
We are not going to speculate on future share repurchase plans.
 
·
Under SEC rules, we are precluded from repurchasing shares during XTOs proxy solicitation period.
 
 
Accounting and Debt
 
·
We will account for this transaction as a purchase, consistent with US GAAP rules.
 
·
US GAAP requires the asset and liabilities acquired to be recognized at fair value. The difference between the fair value of the assets and liabilities, associated deferred taxes and the purchase price is recognized on the books as Goodwill.
 
·
Pro-forma financials are not required. In the first period after closing, combined financial results will be provided.
 
·
We expect that the principal and interest obligations to the holders of XTO bonds will continue to be honored after the transaction closes.
 
 
Hedging
 
·
The XTO business model used hedging to ensure more stable, predictable cash flow.  This is a reasonable and common practice for smaller companies. Given ExxonMobil’s financial strength and diverse portfolio, this will not be necessary.
 
 
XTO
 
·
XTO is a leading U.S. unconventional natural gas producer and has large, high-quality resources, strong technical capabilities, operating expertise and highly skilled employees.
 
·
It was founded in 1986, is headquartered in Fort Worth Texas and has approximately 3,000 employees, all in the United States. About one-third are in Fort Worth and the remainder are in the field or in district offices.

XTO Production & Resource Base
 
·
XTO’s resource base is the equivalent of 45 trillion cubic feet of gas. Proved reserves are the equivalent of 13.9 trillion cubic feet (2.3 billion oil equivalent barrels). Gas represents over 80 percent of XTO’s production and reserves.
 
·
XTO is a top gas producer in the United States and currently produces about 2.4 billion cubic feet per day (Q3-09 total). That represents approximately four percent (4.2%) of current daily U.S. natural gas production (57 BCFD Q3-09).
 
·
XTO has a proven ability to profitably grow production and reserves. XTO has averaged more than 20 percent growth in annual production since 1993.
 
·
XTO’s portfolio is largely unconventional and includes tight gas, shale gas, coal bed methane and shale oil. It is geographically focused in all the major U.S. unconventional plays.
 
·
XTO has a shale gas position in the Barnett shale in North Texas, Haynesville in East Texas and western Louisiana, Woodford and Fayetteville in Oklahoma and Arkansas respectively, and Marcellus shale in Pennsylvania and West Virginia. XTO has a tight gas position in the Freestone Trend in East Texas and in the Uinta Basin in the Rockies.  Also in the Rockies, they hold tight gas and coal bed methane acreage in the San Juan- Raton Basin.
 
·
XTO produces shale oil from the Bakken Shale in the Williston Basin in Montana and North Dakota.
 
 
ExxonMobil Resource Base
 
·
ExxonMobil’s resource base of the equivalent of 72 billion barrels of oil is geographically diverse. Proved reserves are 22.8 billion oil equivalent barrels.  Unconventional gas currently makes up about seven percent.
 
·
ExxonMobil’s current U.S. natural gas production is about 1.3 billion cubic feet of gas per day (Q3-09) or about two percent (2.2%) of daily U.S. natural gas production (57 BCFD Q3-09). Worldwide, ExxonMobil produces about 8.7 billion cubic feet per day.
 
 
Combined ExxonMobil and XTO Resources
 
·
XTO’s assets will complement ExxonMobil’s U.S. unconventional holdings in Piceance and Marcellus, as well as the Horn River Basin in Canada and acreage in Germany, Poland, Hungary and Argentina.
 
·
When combined with XTO’s production, ExxonMobil will produce about six percent (3.7 BCFD or 6.4%) of current U.S. daily natural gas production (57 BCFD).
 
·
When combined, ExxonMobil’s total natural gas volumes are expected to represent approximately 45 percent of ExxonMobil’s total production, slightly higher than today’s mix.
 
·
When combined, ExxonMobil’s unconventional resource portfolio will contain nearly 8 million acres worldwide. This does not include our very large heavy oil assets.

XTO Employees
 
·
XTO has expertise in tight gas, shale gas, shale oil and coal bed methane.
 
·
XTO’s employees are very important to the success of this agreement. They bring the ability to enhance our global operations through the vast experience they have gained in domestic operations.
 
·
While we of course will look for efficiencies, that is not what is driving this agreement. XTO’s employees are recognized for their technical excellence and will be critical in the success of this global unconventional resource organization. Our intention is to retain most of XTO’s employees.
 
 
Combined ExxonMobil and XTO Capabilities
 
·
Following closure of the transaction, our plan is to establish a new ExxonMobil organization to manage global development and production of unconventional resources. It will be based in Fort Worth in XTO’s current offices.
 
·
The new organization will build on the strengths of both companies. It will be a global functional company designed to manage our quality unconventional portfolio.
 
·
The new organization should enable the rapid development and deployment of technologies and operating practices across our global portfolio to maximize resource value.
 
·
XTO’s skills and capabilities when combined 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.
 
 
Safety, Health and Environmental Issues
 
·
ExxonMobil is committed to safety, environmental protection and efficiency and will employ those corporate values in the development of these resources.
