Valero's Strategic Priorities 12 Continue to lower costs Maintain investment grade credit rating Optimize portfolio - continue strategy of the last several years All assets must perform and contribute Paulsboro refinery: continuing to progress on negotiations for potential sale Aruba refinery: conducting maintenance, which provides optionality to operate the refinery under favorable margin conditions Long-term, we expect this refinery will be more valuable to owner of heavy-crude oil reserves Broaden geographic reach - add assets that improve competitiveness Add selective investments in alternative fuels for U.S. market Complete major, value-added capital projects at key refineries Goal: Add long-term shareholder value

Achieving Significant Cost Reductions In 2010, on pace to cut more than $100 million in pre-tax costs in addition to last year's savings of $215 million in pre-tax costs, excluding the benefit from lower energy prices 13 (CHART) (CHART)

Shifting Capital Spending to Economic Growth and Reliability Projects 16 "Stay-in- business" spending 2011 estimated Regulatory spending expected to decline as Benicia air scrubber and MSAT2 projects are completed by year-end 2010 Strategic/economic growth spending is generally flexible and discretionary

Economic Projects Provide Potential for Earnings Growth Large projects have long lead times and were started several years ago Projects have higher implied returns on remaining investment excluding previous spending ("sunk costs") We expect natural gas prices to stay low for years 17 1D&A = depreciation and amortization expense; See Appendix for price assumptions and project descriptions; 2estimated IRR is unlevered; 3Most of project commissioned in 2010 Refinery Project Estimated Com-pletion Date Estimated Cost(millions) Spending thru 2Q10(millions) Estimated Annual Op.

Valero's Gulf Coast System Well-Positioned for Global Export Opportunities 19 Our large, complex, low-cost refineries on Gulf Coast are competitive Exports typically provide a margin benefit Structural supply-demand imbalance in Latin America provides long-term export opportunity (CHART) 1Based on 803 MBPD of average total U.S. gasoline and diesel exports from 2Q09 - 2Q10 On average, Valero's share of U.S. exports of gasoline and diesel has been 30% of the U.S. total Approximately 25% of Valero's Gulf Coast production was exported Strong export capability increases flexibility to place our products in the highest netback markets domestically or globally
