Dear Burlington Resources Employees, As you know, ConocoPhillips has reached an agreement to purchase Burlington Resources. While it will be a number of months before the transaction is formally complete, I'd like to take this opportunity to welcome Burlington Resources to ConocoPhillips and explain why we are so pleased about our future together. Burlington Resources is well known in our industry for operational excellence and technical innovation. Simply put, we believe that Burlington Resources' capabilities, reserves and production assets are an excellent complement to ConocoPhillips' global portfolio of integrated exploration, production, refining, and energy transportation operations. By bringing our two companies together, we will realize opportunities and growth that otherwise would not be possible. You'll probably have many questions about the future of our new company. Rest assured that the management teams of both companies are committed to keeping you informed of important milestones in this transaction. Integration planning for the two companies has just begun. As Bobby told you, a team has been formed with representatives from both ConocoPhillips and Burlington Resources to facilitate this transition. Again, we are very pleased that Burlington Resources will be joining the ConocoPhillips family and look forward to an exciting future. I wish each of you a safe and happy holiday season. Sincerely, Jim Mulva, Chairman and CEO ConocoPhillps ------------------------------------------------------------------------------- CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION FOR THE PURPOSE OF "SAFE HARBOR" PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 Except for the historical and factual information contained herein, the matters set forth in this filing, including statements as to the expected benefits of the acquisition such as efficiencies, cost savings, market profile and financial strength, and the competitive ability and position of the combined company, and other statements identified by words such as "estimates, "expects," "projects," "plans," and similar expressions are forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995.
