    Exploration and Production

natural gas. The company's actual crude oil and natural gas price
realizations may vary from these market indicators due to quality and
location differentials, as well as the effect of pricing lags.

    As anticipated, second-quarter production on a
barrel-of-oil-equivalent basis, including Syncrude, is expected to be
approximately 4 percent below that of the previous quarter. Increased
output in Canada and Venezuela is expected to be more than offset by
the impact of scheduled maintenance at the Bayu-Undan field and in the
North Sea, unscheduled downtime in Alaska, and normal seasonal
fluctuation. Full-year production, including Syncrude, is expected to
be approximately 3 percent higher than the amount produced in 2004.
This excludes the impact of our equity investment in LUKOIL.
Second-quarter exploration expenses are expected to be lower than
those of the prior quarter.

    Refining and Marketing

    The table below provides market indicators for regions where the
company has significant refining operations. The Weighted U.S. 3:2:1
margin is based on the geographical location and capacity of
ConocoPhillips' U.S. refineries. Realized refining margins may differ
due to the company's specific locations, configurations, crude oil
slates or operating conditions. In addition, the company's refining
configuration generally yields somewhat higher distillate volumes and
lower gasoline volumes than those implied by the market indicators
shown below.

    Refining margins for the second quarter are expected to be higher
than those of the first quarter, as indicated in the table above.
Although the WTI/Maya differential narrowed, refining margins continue
to benefit from light-heavy differentials. High crude costs continue
to negatively affect the Refining and Marketing segment due to
fixed-price products that do not necessarily move with the price of
crude. Worldwide marketing margins are expected to improve
significantly over those of the first quarter.
    The company's average crude oil refining capacity utilization rate
for the second quarter is expected to exceed 95 percent.
Second-quarter turnaround costs are expected to be approximately $110
million before-tax.

    Midstream / Chemicals

    The Midstream segment results are expected to be lower in the
second quarter due to the first-quarter net impact to ConocoPhillips
associated with the restructuring of its ownership in Duke Energy
Field Services, LLC (DEFS). At the end of the second quarter,
ConocoPhillips' interest in DEFS remained at 30.3 percent. Additional
transfers related to the restructuring are expected to occur early in
the third quarter of 2005, subject to normal regulatory approvals.
    The Chemicals segment results are expected to be lower primarily
due to lower margins from olefins and polyolefins, as well as lower
margins and volumes from aromatics and styrenics.

    Corporate

    The company expects its debt-to-capital ratio to be approximately
23 percent. In addition, the average diluted shares outstanding during
the second quarter are expected to be 1,419 million shares.
