    Exploration and Production

realizations may vary from the market indicators due to quality and
location differentials, as well as the effect of pricing lags.

    Upstream crude oil, natural gas and natural gas liquids production
on a barrel-of-oil-equivalent per day basis for the quarter is
expected to be approximately 6 percent below second quarter levels, as
anticipated. Third quarter production was impacted by normal seasonal
declines and scheduled maintenance activity in the United Kingdom,
Alaska, and Norway, as well as asset dispositions in the Lower 48.

    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 of ConocoPhillips' U.S.
refineries. Realized refining margins may differ due to the company's
specific locations, configurations, crude oil slates or operating
conditions.

    The weighted U.S. refining margin for the third quarter is
expected to be higher than the second quarter. Improved refining
margins are expected to be partially offset by lower marketing
margins. The company's average crude oil refining capacity utilization
rate for the third quarter is expected to be in the mid-90 percent
range.

    Midstream/Chemicals Businesses Segments

    Third quarter Midstream results are expected to be lower than the
second quarter primarily due to lower equity earnings. This segment
reflects ConocoPhillips' 30.3 percent interest in Duke Energy Field
Services, as well as consolidated midstream operations.
    Chemicals' third quarter results are expected to decline from the
second quarter primarily due to lower margins, partially offset by
increased volumes.

    Corporate

    Corporate expenses from continuing operations during the third
quarter are expected to be lower than the previous quarter.
    The company's balance sheet debt level at the end of the third
quarter is expected to be $18.9 billion. This reflects debt reductions
of approximately $1.5 billion during the third quarter, as well as
accounting changes that increased balance sheet debt by approximately
$2.9 billion as a result of the adoption of Financial Accounting
Standards Board (FASB) Interpretation No. 46 (FIN 46), "Consolidation
of Variable Interest Entities," and FASB Statement No. 150 (SFAS 150),
"Accounting for Certain Financial Instruments with Characteristics of
Both Liabilities and Equity." FIN 46 was adopted during the third
quarter, with retroactive application as of Jan. 1, 2003, while SFAS
150 was adopted and applied as of July 1, 2003.
    The company's effective tax rate is expected to be approximately
50 percent. Second quarter effective tax rates were lower than normal,
primarily due to the impact of one-time international E&P tax
legislation changes.
    The company anticipates that its synergy run rate will remain on
track to reach $1.25 billion per year by the end of 2003.
