Successful Cost Savings Programs Successful Cost Savings Programs 14 Ongoing cost savings programs have contributed to Valero's competitiveness and improved financial performance2011 goal is $100 million, but expect to reach $200 million for year millions (CHART)

Refinery Yield Improvements Contribute to Higher Margin Capture 15 Note: Does not include Aruba, Pembroke, Meraux, Paulsboro or Delaware City refineries Higher-value products and liquid volume yield are important with high crude pricesLiquid products have a much higher value than solid products like coke and sulfurValero's focus on liquid volume yield achieved an increase of 0.4% in 2010 versus 2009Via optimization of refining units, catalysts, and feedstocksEstimated improvement was worth $242 million using 2010 prices2011 YTD estimated improvement is $48 millionIn current price environment, each 0.1% improvement generates about $60 million in additional EBIT each yearExpect another 1.4% improvement by 2013 for entire system after hydrogen and hydrocracker projects are operating

Valero's Key Economic Projects Capture the Natural Gas to Crude Oil Spread Crude oil has traded at 3x to 4x the energy-adjusted price of U.S. natural gasRefiners are looking for ways to eliminate the need to produce hydrogen from crude oilHistorically refiners have produced hydrogen from oil via the reformer unitReformers also make high-octane gasoline, which in not needed because the blending of high-octane ethanol is mandatedProducing hydrogen from natural gas allows refiners to reduce throughput or shutdown traditional reformer unitsSteam-methane reformers produce hydrogen from natural gasHydrogen has become more important with the need to remove sulfur from fuels and is particularly important in diesel productionDiesel demand is outpacing gasoline demand and setting refinery ratesFor large increases in diesel yields, capital investment is required with hydrocracking technology being the best choiceHydrocrackers are preferred due to high level of liquid volume gain which, can be up to 30% 22

Our Two Hydrocracker Projects Are Progressing on Schedule and on Budget 23 Recently increased planned operating rates from 50,000 BPD to 60,000 BPD for St. Charles and 57,000 BPD (rolling 12-month average per permit) for Port ArthurNo additional capital costsIncreased capacity improves economicsExpect EBITDA to improve by a combined $93 million annuallyProject internal rate of return expected to improve by 1.6% at Port Arthur and 2.7% at St. CharlesProjects remain on schedule and on budget with full impact expected in 2013Estimate Port Arthur complete 3Q12 and St. Charles complete 4Q12 St. Charles Site St. Charles HCU Reactor Port Arthur Site

Improving Valero's Competitiveness by Increasing Distillate Yield Valero's refinery distillate yields are expected grow by about than 7% by 2013Distillate production volumes will increase by over 300 MBPD versus 2010 including the impact of acquisitions and hydrocracker projectsIncreasing distillate yields improves portfolio competitivenessDistillate is the highest demand product globallyGrowth is expected to outpace gasolinePrimary driver for increase is the completion of hydrocracker projectsRecent acquisitions have also increased refinery diesel-to-gasoline ratio 24 (CHART) Note: Gasoline and distillate as a percent of total production; Distillate includes jet fuel

Why Valero Is an Excellent Buy Today Good fundamentals, particularly for diesel, with potential upside from economic recoveryImproved refinery performance as shown in industry surveysAchieved significant overhead cost savings Increased liquid volume yields and use of lower-cost feedstocksImproving competitiveness of refining portfolioAdded quality assets at attractive prices while diversifying business mix and geography: Ethanol, Pembroke, MerauxReturning cash to shareholders via buybacks and dividendsGoal to pay one of the highest dividend yields in our peer groupProgressing on key growth projects that should add significant earnings and cash flow in late 2012 and 2013 25

Appendix 26

Meraux Refinery Utilizes Flexible Feedstock and Product Slate Significant feedstock flexibilityConsuming feedstocks mix from 80% medium sour to 80% light sweet grades depending on crude oil economicsPipeline connectivity to LOOP opens ability to process dozens of foreign crude grades in addition to Mars and other U.S. Gulf Coast crudesCan shift product yields between 60/40 and 50/50 mix of gasoline/distillate40%+ distillate yield is high for typical U.S. refineryProducts placed through three main methods: Colonial and Plantation pipelines via equity interest in Collins Pipeline, adjacent product terminal, and refinery dockRefinery produces export-quality diesel that can be loaded via refinery-owned dockCrude oil pipeline expansion in early 2012Will enable 100% of crude slate to be delivered by pipeline, which frees up capacity at dock facilities to export products 27 (CHART) (CHART)

Made Excellent Ethanol Acquisitions Built position for average of only 35% of estimated replacement cost2Q09: acquired 7 plants with 780 million gallons per year of world-scale capacity in advantaged locations1Q10: Added 3 plants with 330 million gallons per year of capacity 32 Favorable margin outlookHigh crude oil prices support ethanol pricesInternational demand supporting margins 2011 ethanol mandate grows 5% over 2010Expect demand to outgrow capacity, but blend wall must be addressed To incentivize new builds, margins must be high enough to yield reasonable return on higher-cost, new-build plantsValero's low-cost acquisitions of high-quality plants imply a competitive advantage in any margin environmentProvides platform for future production of advanced biofuels

Valero's Gulf Coast System Well-Positioned for Global Export Opportunities 33 Our large, complex refineries on Gulf Coast are competitive due to low-cost operations and feedstocksStructural supply-demand imbalance in Latin America and diesel-shortage in Europe provide higher-margin export opportunitiesLow-cost natural gas is a competitive cost advantage versus other global refiners(CHART) 1Based on 966 MBPD of average total U.S. gasoline and diesel exports from 1Q09 - September 2011
