Re:      Thanks for a smooth transition

Date:    June 22, 2004

     I  am  extremely  pleased  to  announce  that  staffing  for  the  combined
Kerr-McGee and Westport  Resources  organization is complete.  We appreciate the
collaborative  effort from  everyone  involved in this  important  aspect of the
pre-merger activities. Your commitment to expedite this transition will ensure a
smooth   integration  of  our  two  companies  if  the  merger  is  approved  by
shareholders on Friday, June 25.

     This  week,  all  members  of  my  management  team  will  introduce  their
respective  organizations.  The  corporate  intranet  site will have all updated
organizational charts by July 1.

     Our  consolidated  organization  will be strong.  We will  achieve  various
synergies,  efficiencies  and  ultimately  the $40 million  cost savings that we
projected  at the time we announced  the merger April 7. I am confident  that we
have capitalized on the high quality assets and the human resource  strengths of
both Kerr-McGee and Westport Resources.

     We have an exciting and bright future at Kerr-McGee.
