VLO Well-Positioned to Benefit from Return- Enhancing Trends Competitively exporting into growing marketsAtlantic Basin closures reducing excess capacityIncreasing Valero's yield of distillates, which have higher margins and growthLow-cost U.S. natural gas provides competitive advantageExpect abundant and growing U.S. shale oil and Canadian production to provide feedstock cost advantage, which increases in the future 6

Competitively Exporting into Growing Markets Source: DOE Petroleum Supply Monthly with YTD data as of November 2011, Latin America includes South and Central America plus Mexico U.S. has become a net exporter of refined products due to growth in developing countries, Atlantic Basin capacity closures, Western European diesel demand, and Latin American refining operating issuesU.S. Gulf Coast (PADD III) is largest source of exported productsLatin America continues to be the largest U.S. export market, followed by Western EuropeLatin American petroleum demand has been increasing 2.5% per year over the past 5 years versus U.S. decreasing 1.8% per year 7 (CHART) U. S. Product Exports By Destination U. S. Product Exports By Source (CHART) MMBPD

Valero's Gulf Coast System Taking Advantage of Global Export Opportunities 8 Our large, complex refineries on Gulf Coast are competitive due to low-cost operations and feedstocks flexibilityIncreasing export capability to take advantage of growing export opportunities(CHART) 1Based on 1,001 MBPD of average total U.S. gasoline and diesel exports from 1Q09 - November 2011

(CHART) Atlantic Basin Closures Reduce Excess Capacity Capacity closures have been concentrated in the Atlantic Basin: U.S. East Coast, Caribbean, Western EuropeCombined with poor utilization in Latin American refineries and demand growth in Latin America, creates opportunity for competitive refineries to export quality products 9 (CHART) Sources: Industry and Consultant reports and Valero estimates

Product Margins Responding to Atlantic Basin Closures 10 With recent closures, Atlantic Basin product margins have increased significantly from 4Q11 levelsIn addition, expect above-average U.S. turnaround (maintenance) activity throughout the industry to affect production capacity in 1H12 (CHART) Source: Argus, 2012 YTD through February 3, 2012 /bbl

Valero Increasing Distillate Yields 11 (CHART) Source: Company Reports and EIA, yield data is for 2010; gasoline and distillate as a percent of total production volumes; distillate includes jet fuel Valero's refining system distillate yields are expected to grow from 33% to 39% in 2013Primary driver for increase is the completion of hydrocracker projects in 2012Recent acquisitions have also increased distillate yields (CHART)

Capital Program Focused on Completion of Large Economic Growth Projects 21 "Stay-in-business" spending 2012 capital high due to estimated completion of economic growth projects, mainly the hydrocrackersExpect a significant decline in capital spending after 2012 $1,740 $1,735 $1,645 $1,565 Total$2,000 to $2,500 Decline $435 to $935

Managing Financial Strength and Growing Cash Yield Expect significant contributions of free cash flowReduction in 2013 capital spending Cash flow expected from operation of major projects to be started-up in 2012Returning cash to shareholdersTripled quarterly dividend in 4Q11 to $0.15 per shareIn 2011, bought 16.7 million shares, or 3% of outstanding shares, for $347 million, and so far in 2012, bought 1.8 million shares for $38 millionGoal is to have one of the highest cash yields among peersEnded 2011 with $1.0 billion of cash and $4.5 billion of additional liquidityInvestment grade credit rating is a priorityPaid off $778 million of debt in 2011Net debt-to-cap ratio at 12/31/11 was 29%Far below credit facility covenant of 60%No other coverage-type ratios or borrowings on bank revolver 22

Valero's Strategic Priorities 23 Constant focus on safety, environmental, and regulatory complianceMaintain investment grade credit ratingContinue improvement in refining performance to 1st quartile levelsContinue cost reduction effortsComplete major, value-added capital projects at key refineriesOptimize portfolio - continue "high-grading" strategySuccessfully integrate new acquisitions into portfolio and capture synergiesEvaluate dispositions of poor performing assetsEvaluate attractively priced, strategic, and accretive acquisitions that improve competitivenessAdd selective investments in retail and alternative fuels Goal: Increase long-term shareholder value

Why We Believe Valero Is an Excellent Buy Today Well-positioned to benefit from return-enhancing trendsBenefiting from strong export marketAtlantic Basin capacity closures have improved refining fundamentalsProjects focus on taking advantage of low-cost natural gas, high oil prices, and higher distillate demand and marginsExpect abundant U.S. shale and Canadian crude oil production to provide a cost advantage to U.S. Gulf Coast refiners versus global, coastal (including U.S. East Coast) light/sweet refinersStrong performance and free cash flow from ethanol and retailImproving performance and competitiveness of refining portfolioKey growth projects and falling capital expenditures should contribute significant free cash flow in late 2012 and 2013Returning more cash to shareholdersGoal to have one of the highest cash yields among peers 24

U.S. Gasoline Exports by Destination Most of the gasoline export growth this year has been to Latin America, including Mexico Latin American requirements are growing due to increased demand and poor performance of refineries in Venezuela and MexicoShutdown of St. Croix and possibly Curacao will add to their shortfall Note: Gasoline represents all finished gasoline plus all blendstocks (including ethanol, MTBE, and other oxygenates)Source: DOE Petroleum Supply Monthly with YTD data as of November 2011. 4 Week Average from Weekly Petroleum Statistics Report (CHART) MBPD 51

U.S. Diesel Exports by Destination Diesel exports to Latin America continue to exceed exports to Europe, but over two- thirds of diesel export growth in 2011 was to Europe Source: DOE Petroleum Supply Monthly with YTD data as of November 2011. 4 Week Average from Weekly Petroleum Statistics Report Lower European refinery runs on challenging economics forced the region to import more diesel Expect Petroplus' refinery shutdowns will add to European diesel deficitLatin America needs remain high on good demand growth and continued challenges running refineries in key countries (CHART) MBPD 53

55 U.S. Crude and Natural Gas Production - Tight Oil Supply Growth The furthest along in development are in North Dakota (Bakken) and South Texas (Eagle Ford)Each could see 500+ MBPD of growth in the next few years and potentially more thereafterUtica (Ohio) is potentially a large play, but is not as far along in development and is 3 to 5 years away Source: Map from CERA Shale Oil Plays in North America Expect supply growth will exceed regional demand, and excess will clear toward the Gulf Coast, pushing out imports The new U.S. shale plays are located in places that should provide additional barrels into the Rockies and Gulf Coast - pressuring crude imports and lowering natural gas prices
