The following is a memorandum that was sent to all Burlington Resources
Canada employees and first posted on Burlington Resources Inc.'s intranet
web site on March 1, 2006.

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.
