TO: ALL BURLINGTON RESOURCES CANADA EMPLOYEES SUBJECT: CONOCOPHILLIPS-BURLINGTON RESOURCES INTEGRATION - HR UPDATE DATE: MARCH 1, 2006 When the proposed ConocoPhillips-Burlington Resources transaction was announced late last year, an important part of the vision was the opportunity it would create, both for the company and for employees. As we get closer to potential consummation of the transaction, those opportunities are being captured across the organization. Over the last couple of months we have shared information with you about the integration of our companies. Now we'd like to talk with you about what the integration means to you and your family. While we realize not all Burlington Resources employees will be joining the new company, we assure you that our intent is to treat everyone fairly and with respect. One of our key objectives for employees from Burlington Resources is to make the integration as seamless as possible. One example of this is that your benefits and compensation programs through Burlington Resources will continue for 2006. Even so, we realize you may want to know about ConocoPhillips' programs, and what your compensation and benefits may look like for 2007. ConocoPhillips offers a very competitive package comprised of compensation, retirement, savings, health benefits, career development opportunities, and work/life programs. More information about these programs is on the way. As we move forward with the integration, we will provide you with information as quickly as we can. In fact, we already have plans in place to provide more details through the following: o Employee meetings, town halls, and other "live" forums will provide a chance to share information and allow for two-way discussion so that you can ask questions and get answers. o A mailing to your office address will provide more details for you about ConocoPhillips' compensation and benefits package, and provide a means for you to share this information with your family or others close to you. o Notification letters will be distributed beginning in mid-March. As always, should you have any questions, we encourage you to visit the integration site or talk with your manager. For questions regarding your 2006 Burlington Resources benefits, please continue to call your Burlington Resources contacts. You can also visit the hr.conocophillips.com Web site, or contact HR Connections at 1-800-622-5501 or HRConnections@conocophillips.com for more information. We are excited about what the future holds for our new company. Burlington Resources is a critical part of ConocoPhillips' future success, and we look forward to continuing our dialogue.
