On December 14, 2005, the following memo was sent on behalf Jim Mulva,
Chairman and Chief Executive Officer of ConocoPhillps, to all Burlington
Resources Inc. employees.



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
