 .  Overall, industry fundamentals and favorable expense performance helped

   .  Expense performance continued to be favorable.
   .  Exploration expenses were lower.
   .  Volumes from growth areas were up significantly; however, overall
      production was down about 3 percent primarily due to contractual
      reductions in Indonesia.

   prices.
   .  U.S. Marketing and Refining experienced a significant amount of
      unscheduled refinery downtime which has been rectified.
