High Conversion Refining System High Conversion Refining System 5 Note: CDU = crude distillation unit; conversion capacity is the sum of each company's FCC, hydrocracking, and coking capacity Source: PIRA Energy Group 12/16/10 (CHART) We believe size and conversion ratio matter to competitiveness Provides flexibility to process a wide variety of discounted feedstocks into a high proportion of high-value clean products

Strong Contribution from Retail and Ethanol (CHART) Retail Performance (Trailing 4Q Avg.) (U.S. and Canada) 6 Acquired world-class ethanol plants at an average of 35% of replacement cost Large, efficient plants in great location have competitive advantage on costs Valero initiatives achieving 6% higher ethanol production than prior owners In 2010, retail had best 1st and 2nd quarters in Valero history Consistent improvement in retail earnings with smaller asset base Since 2005, more than doubled total operating income on 12% fewer total sites (CHART) Ethanol Operating Income (millions)

(CHART) (CHART) Continued Global Demand Growth Important to Refining Margins Refining is a global business - global demand growth matters to refiners everywhere U.S. and global economic forecasts show growth and upward revisions Strong growth in emerging markets is leading the surge in global demand, similar to 2003-2005, estimated at 2.5 million BPD in 2010 8 Source: Consultant and Valero estimates Source: Consultant and Valero estimates MMBPD MMBPD Forecast Forecast

Refining Industry Margins Bottomed in 2009, Recovery Started in 2010 9 Gulf Coast Gasoline and On-road Diesel Margins vs. WTI Plentiful spare capacity and product inventories squeezed margins in 2009 Margins improving from strong global demand, particularly in emerging markets, and capacity rationalization Recent cold weather in OECD countries helping distillate demand and margins Long term, expect growth in distillate demand will continue to outpace gasoline per bbl Source: Argus; 2010 year-to-date through December 30 YTD YTD

Nearly 2/3 of Valero's feedstocks are lower-quality and discounted versus light-sweet crude oil Expect key drivers of sour crude discounts to continue in 2011: OPEC increasing production, some of which is lower-quality and heavier crude Light product demand outpacing heavy product demand growth Supply of low-quality crudes from Latin America has been better than expected Longer term, expect to benefit from Canadian heavy crude oil to Gulf Coast Feedstock Discounts Also Rebounded in 2010 Sour Crude Percentage Discounts below WTI Source: Argus; 2010 year-to-date through December 30 Sour Crude Discounts below WTI (per bbl) Source: Argus; 2010 year-to-date through December 30 10 YTD YTD (CHART) (CHART)

Valero's Strategic Priorities 12 Continue to manage costs Maintain investment grade credit rating Optimize portfolio - continue "high-grading" strategy of the last several years Asset Sales: closed on the sale of Paulsboro refinery and Cameron Highway Oil Pipeline during 4Q10 These two transactions generated $877 million ($1.54/share) in cash before taxes in the fourth quarter Aruba refinery: After recent investments, refinery is now operating and in improved condition Current margins indicate profit contribution in 1Q11 Long-term, this refinery offers avoided-cost opportunity for heavy oil upgrading and logistics to growing markets Evaluate attractively priced acquisitions that improve competitiveness and broaden geographic reach Add selective investments in alternative fuels for U.S. market Complete major, value-added capital projects at key refineries Goal: Increase returns to grow long-term shareholder value

Achieving Significant Cost Reductions In 2010, on pace to cut more than $185 million in pre-tax costs in addition to last year's savings, excluding the benefit from lower energy prices 13 (CHART) (CHART)

Shifting Capital Spending to Economic Growth and Reliability Projects 17 "Stay-in- business" spending 1 The 2011 capital budget is under review given the potential benefits of a recently passed tax law allowing 100% deduction on capital projects. We expect to accelerate spending on economic- growth projects, which would increase spending in 2011 up to $300mm before the cash tax benefits that may substantially offset the increase in spending 2011 estimated Regulatory spending expected to decline as Benicia scrubber and MSAT2 projects were completed in 2010 1 1

Economic Growth Projects Mainly Geared Toward High Oil/Low Natural Gas Prices Projects developed based on our "bullish crude, bearish natural gas" price outlook These projects represent over 75% of strategic capital spending in 2010 and 90% in 2011 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") 18 1D&A = depreciation and amortization expense; See Appendix for price assumptions and project descriptions; 2estimated IRR is unlevered and likely improve due to recent changes in tax laws regarding accelerated depreciation expense; 3Most of project commissioned in 2010 Refinery Project Estimated Com-pletion Date Estimated Cost (millions) Spending thru 3Q10 (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 Low-cost natural gas is a competitive cost advantage versus other global refiners Structural supply-demand imbalance in Latin America provides export opportunity (CHART) 1Based on 803 MBPD of average total U.S. gasoline and diesel exports from 3Q09 - 3Q10 On average, Valero's share of U.S. exports of gasoline and diesel has been 31% of the U.S. total Approximately 26% 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
