PRODUCTION SLIPS: Oil and gas production fell 1.8 percent, resulting in lower earnings for the so-called upstream end of the business. Most of Exxon's profit comes from producing oil and gas outside the U.S.

REFINING OFF TOO: Profit margins in refining continued to shrink, further cutting into Exxon's profit. Earnings from the company's "downstream" business plunged 48 percent from a year ago.
