     To  facilitate  the  desired  integration  of our  organizations,  we  have
identified a Transition Team and an Executive  Steering  Committee to coordinate
the effort overall for  Kerr-McGee  and Westport to ensure that the  appropriate
employees   are   involved  in  the   process.   Activities   will  include  the
identification  of efficiencies to be gained by the Kerr-McGee - Westport merger
in all areas of operations and shared  services.  The team also will develop the

for  Kerr-McGee,  as we build on this merger.  We will strive to accomplish  our
stated goals and emerge as a strong,  efficient  and  consolidated  organization
