2006 Upstream Technology WebcastAugust 30, 2006

Forward-Looking Statements. Outlooks, projections, estimates, targets, and business plans in this presentation are forward-looking statements. Actual future results, including the outcome of our research programs and the development, deployment, cost, timing, and benefits of new technology and technology improvements could differ materially due to a number of factors. These include changes in long-term oil or gas prices or other market conditions affecting the oil and gas industries; reservoir performance; changes in law or government regulation; the outcome of commercial negotiations; the actions of competitors; the development of competitive technologies; unforeseen technical difficulties; and other factors discussed here and under the heading "Factors Affecting Future Results" on the Investor Information section of our website at www.exxonmobil.com.

Frequently Used Terms. References to resources and similar terms indicating quantities of oil and gas include amounts that are not yet classified as proved reserves but that we believe will likely be moved into the proved reserves category and produced in the future. References to reserves generally exclude year-end pricing effects and include ExxonMobil’s share of equity companies as well as tar sand reserves. For definitions and additional information regarding certain terms used in this presentation, including information required by SEC Regulation G, see the "Frequently Used Terms“, quarterly 8-K filings regarding results of operations and financial condition, and other material posted on the Investor Information section of our website. The 2005 Financial and Operating Review on our website also contains important information including ExxonMobil's net interest in specific projects.
