Key Market Trends 6 Expect dramatic growth in U.S. shale oil and Canadian oil production to provide North American crude oil cost advantage Expect shale development to drive strong growth in supply of natural gas liquids and naphtha Industry installing significant infrastructure to move crude oil to refining markets, mainly to U.S. Gulf Coast Lower-cost North American natural gas provides competitive advantage and upgrading opportunities Global distillates demand growth yields higher margins U.S. Gulf Coast competitively advantaged to export into growing and undersupplied markets, taking market share from Western Europe and replacing shutdown and underperforming refining capacity in the Atlantic Basin

U.S. and Canadian Production Growth Provides Resource Advantage to North American Refiners Resource Advantage to North American Refiners Resource Advantage to North American Refiners 7 Source: EIA, Consultants, company announcements and Valero estimates; 2013 U.S. Crude imports are YTD as of June 2013 Crude production growth reduces similar quality imports Largest growth coming from U.S. shale crude and heavy Canadian crude

U.S. Gulf Coast: Main Destination for Cost-Efficient Crude Oil Pipelines Rapid increase in pipeline capacities to move inland North American light and heavy crude oils to the Gulf Coast Light crudes have been pricing below LLS in western (Houston, Corpus) parts of Gulf Coast Recent completion of pipelines and increased flows are building crude oil inventories in the Gulf Coast and increasing supply above demand - which should aid discounts Expect Valero to benefit with over 50% of its refining capacity on the Gulf Coast (CHART) Source: Consultants, company announcements and Valero estimates Note: Import volumes include light and medium crudes between 28 and 50 API with less than 0.7% sulfur; 2013 data is year-to-date through June U.S. GC Light/Medium Sweet Imports 8

Valero's Strategy to Supply Incremental Volumes of Cost-Advantaged Crude Oil Volumes of Cost-Advantaged Crude Oil Volumes of Cost-Advantaged Crude Oil 9 Expect Quebec refinery to benefit and become supplied by U.S. and Canadian crude in three ways: rail, ship, and pipeline Railing up to 30 MBPD of light crude started in August 2013, increasing to 50 MBPD in 4Q13 Shipping Eagle Ford crude from Texas via lower-cost foreign-flagged vessels Committed to receive substantial volume of light crude via Enbridge pipeline 9B and shuttled from Montreal by ship in 1Q15, based on Enbridge's revised timing

Lower-Cost Natural Gas Provides Structural Advantage to U.S. and Canadian Refiners 11 Note: Per barrel cost of 700,000 MCF/day of natural gas consumption at 90% utilization (2,529 MBPD) of Valero's capacity $1.5 billion higher pre- tax annual costs $3.1 billion higher pre-tax annual costs Due to significant production associated with shale basins, expect U.S. natural gas prices will remain low and disconnected from global oil and LNG prices for foreseeable future Natural gas is a cost-advantaged feedstock, not just an operating expense advantage Conversion to hydrogen provides desulfurization and liquid volume expansion VLO refinery operations consume up to 700 MMCF/day of natural gas at full utilization, split roughly in half between operating expense and cost of goods sold

Global Distillates Demand Growth Yields Higher Margins 12 (CHART) Source: Argus, 2013 YTD through September 20, 2013 /bbl (CHART) Diesel growth rate 2x gasoline Distillates (diesel, kero, jet fuel) margins are significantly higher than gasoline due to less spare distillates production capacity Distillates demand growth rate is much higher than gasoline Europe continues to be short diesel, but long marginal refining capacity and processing expensive crude oils and natural gas

U.S. Refining Capacity Is Globally Competitive and Taking Market Share 13 U.S. flipped from importer to exporter on lower local demand and competitive advantages U.S. refiners in PADDs 2, 3, and 4 have higher utilization due to structural advantages of cost-advantaged crude oil and natural gas U.S. Gulf Coast refineries have taken market share in the Atlantic Basin via growing exports Source: EIA and IEA, data as of June 2013 (CHART) Refinery Utilization by PADD, Trailing 12-months These regions have less-competitive capacity "Mid- con" "Gulf Coast" "West Coast" "Rockies" "East Coast" (CHART) U.S. Net Product Imports Source: EIA, data annual through 2012 "Western Europe"

(CHART) Continued Global Demand Growth Important to Refining Margins 15 Source: Consultant and Valero estimates World Petroleum Demand Growth MMBPD Emerging markets lead in terms of global petroleum demand growth Particularly strong growth in Latin American countries and China Refining is a global business - world growth impacts refiners in every market because products are generally very storable, transportable, and fungible commodities

(CHART) World Refinery Capacity Growth Estimated Net Global Refinery Additions 16 MMBPD Source: Consultant and Valero estimates; Net Global Refinery Additions = New Capacity + Restarts- Closures Expect significant new global refining additions in the next several years Mainly new plants in Asia and the Middle East, where demand growth is strong New capacity announcements from Brazil, Mexico, and Colombia will likely be much smaller and much later than originally announced Other projects unlikely because of costs and other factors: Ecuador, Peru, Algeria, Egypt Due to yields, cost structure, and declining or flat demand growth, we expect continued refinery shutdowns (primarily in Europe, Australia, and Japan)

Valero's 2013 and 2014 Capital Spending Focus on Growth Investments 17 "Stay- in- business" spending 2013 spending includes approximate $60 million for retail (CST Brands) through April Total $3,000 Total $2,850

(CHART) Valero's 2013 and 2014 Growth Investments Focus on Logistics and Crude 18 Growth investments consist mainly of logistics and crude fractionation, which are 50% of 2013 and 67% of 2014 total growth spending (CHART) 2013 Growth Investments 2014 Growth Investments Total estimate $1.335 billion Total estimate $1.505 billion Hydrocracking Nat gas / NGL upgrading & Petchems Other Processing Light Crude Oil Logistics Logistics Hydrocracking Nat gas / NGL upgrading & Petchems Processing Light Crude Oil Other

Logistics Growth Investments Strategy Increase access to cost-advantaged crudes for refineries Increase capability to export more products and crude Investments Pipelines, rail cars, rail unloading, barges, ships, docks, tanks Purchased 5,320 rail cars for delivery 4Q12 through 2Q15 Crude rail unloading terminals at Quebec (2013), St. Charles (2013), and West Coast refineries (2015) Quebec crude oil logistics to deliver crude oil from Enbridge Line 9 reversal, includes tankage and ship Facilities for increased exports of products and export of crude oil from Gulf Coast to Canada 19 Expect most assets qualify for MLP drops

Expect to Unlock Value via New MLP Valero Energy Partners LP filed a draft registration statement on September 19 Expect initial public offering in first half 2014 Expect to trade on NYSE using ticker VLP S-1 available from SEC's website under Valero Energy Partners LP Seeking value creation through higher valuation of logistics earnings Logistics MLPs trade at 10x to 15x EBITDA versus refiners and VLO at 3x to 5x EBITDA Focusing on logistics assets with predictable and stable EBITDA Pipelines, docks, terminal tankage, marketing racks, rail cars, rail unloading facilities, ships, and barges 20

Strategy Designed to benefit from our outlook of: High crude and low natural gas prices Strong global distillate demand growth and margins Growth Investments 57 MBPD hydrocracker at Port Arthur refinery performing well New 60 MBPD hydrocracker at St. Charles refinery reached full rates in August Hydrocracking Growth Investments 21 50 MBPD in lower-cost hydrocracker expansion projects available in future Estimated cost per barrel is approximately 60% lower than the recent grassroots units Expand Meraux hydrocracker by 20 MBPD and increase distillate yield in early 2015 Expand new Port Arthur and St. Charles hydrocrackers each by 15 MBPD in 2018, delayed from 2015 In addition, new ~10 MBPD Diamond Green Diesel JV plant now operating Uses hydroprocessing technology to make Renewable diesel from waste cooking oil, animal fat, corn oil New St. Charles Hydrocracker

Investments to Process More Domestic Light Crude Oil Strategy Increase processing of North American cost- advantaged crude oil versus feedstock purchases Use underutilized conversion capacity Sites selected due to configuration of oversized conversion capacity relative to crude capacity; and bottoms-cracking capability Growth Investments Two new crude oil topping units expected to come online in late 2015 90 MBPD at Houston refinery 70 MBPD at Corpus Christi refinery Relatively low cost per barrel of daily throughput capacity Expect unlevered IRRs greater than 30% McKee crude unit expansion of 25 MBPD expected in first half of 2015 Evaluating low-cost projects to unlock light crude capacity at Port Arthur and Meraux 22 (CHART)

Upgrading Natural Gas to Methanol Strategy Bolt-on approach leverages existing assets Gas-to-liquids upgrading U.S. is a growing methanol market and represents about 10% of the global market On average, the U.S. imported about 89% of its supply (about 5 million tonnes per year) Southern Louisiana is the largest hub for imports of methanol to the U.S. Primary uses for methanol are for production of formaldehyde, acetic acid, and other chemicals Global demand is growing, particularly in Asia Growth Investment 23 Evaluating the construction of world-scale methanol plant at our St. Charles refinery Capacity of 1.6 to 1.8 million tonnes/year (36,000 to 40,000 BPD) Captures price spread between low-cost natural gas and methanol Unlevered IRR expected >30% with natural gas below $6.50/mmBtu and $100/barrel crude Methanol is a very cost-efficient way to move natural gas to higher-value foreign markets Capital cost estimate is about 50% of grassroots and 33% less than a relocation Leverages existing refinery hydrogen infrastructure to upgrade low-cost syngas into methanol Project startup is expected in 2017 Competitive advantages lie in lower capital cost and plant operation (CHART) Source: Argus/JJA

(CHART) NGLs and Naphtha Upgrading Presents a Valuable Opportunity Strategy Consistent strategy - feedstock advantage and bolt-on/synergistic project Expect supply of NGLs plus naphtha-rich condensate to grow along with shale crude development in the U.S. and Canada Expect length in the domestic NGL and naphtha supply will create structurally lower prices versus global markets Growth Investment Expect to construct a new 12.5 MBPD alkylation unit at our Houston refinery Estimated startup in early 2017 Unlevered IRR expected to exceed 30% Conversion of NGLs (butanes and pentenes) into alkylate, a higher-value gasoline blendstock Captures large price spread between isobutane and alkylate (premium gasoline) 24 Source: Consultant and Valero estimates; NGL supply includes ethane, propane, butane, and natural gasoline (CHART) Source: Argus Estimate ~4% average annual growth from 2012 to 2020

(CHART) Returning More Cash to Stockholders and Managing Financial Strength Spun off 80% of company operated retail, equivalent to about $3.50 per share of VLO Valero retained 20% of CST common stock Returning more cash to stockholders Increased quarterly dividend from $0.05 per share in 2Q11 to $0.225 per share in 3Q13 Bought 14.2 million shares so far in 2013, and 27.3 million shares in 2011 and 2012 combined Goal is to have one of the highest cash yields among peers via dividends and buybacks Maintaining investment grade credit rating is a priority Paid off $480 million of debt in 2013 Reduced debt by $558 million in 2012 Net debt-to-cap ratio at 6/30/13 was 18.8% 25 Cash Returned to VLO Stockholders Source: 2013 EPS estimates from First Call as of 9-23-13 Note: 2013 YTD through September 11, 2013 (CHART)

We Believe Valero Is an Excellent Buy Today Expect dramatic growth in North American oil, gas, and NGL production Industry installing significant infrastructure to move crude oil to refining markets - mainly to U.S. Gulf Coast Lower-cost U.S. and Canadian natural gas provides competitive advantage Global distillate demand growth yielding higher margins U.S. competitively exporting into growing and undersupplied markets Balanced approach of investment and cash returns to all stockholders Invest in growth projects that exploit North American resource advantages Logistics, hydrocracking, processing more domestic light crude oil, plus natural gas, NGLs, and naphtha upgrading projects (petrochemicals, alkylation) Expect excellent stockholder returns and value - building on industrial base Unlock potential value of existing assets Spun off retail assets into publicly traded CST Brands Pursuing MLP for our growing portfolio of logistics assets Return cash to stockholders Seek to grow regular dividend at sustainable rate Concentrate value per share via stock buybacks 28 Key Market Trends Valero's Strategy

Appendix 29

Valero's Ethanol Segment Total nameplate production capacity of 1.1 billion gallons/year Built position for average of only 35% of estimated replacement cost 2Q09: Acquired 7 plants with 780 million gallons per year of world- scale capacity in advantaged locations 1Q10: Added 3 plants with 330 million gallons per year of capacity Valero's low-cost acquisitions of high-quality plants imply a competitive advantage in any margin environment Expect weaker capture rates in 3Q13 versus 2Q13 due to backwardated market structure for corn 30 Note: 2013 YTD EBITDA through 2Q13 (CHART)

Valero Increasing Distillate Yields 31 (CHART) Source: Company Reports and EIA, yield data is for 2012; gasoline and distillate as a percent of total production volumes; distillate includes jet fuel; gasoline excludes naphtha Valero's refining system distillate yields are estimated to grow from 33% in 2010 to 39% in 4Q13 and 43% in 2015, yielding a gasoline/diesel ratio of nearly 1:1 Primary driver for increase is the construction of two new hydrocrackers at Port Arthur and St. Charles, plus planned expansion at Meraux (CHART) Nearly a 1:1 ratio

Unlocked Value via Retail Spinoff Spun off to stockholders our retail business on May 1 CST Brands, Inc. trading on the NYSE under the ticker symbol "CST" CST has traded at more than double the earnings valuation of VLO, unlocking shareholder value Valero received approximately $500 million in net cash Net of tax liability and working capital benefit to CST Valero retained 20% of CST common stock 15 million shares valued at approximately $450 million based on recent CST market prices Intend to liquidate within 18 months of the distribution CST Brands is now Valero's largest wholesale customer Valero provides CST with ethanol-blended fuels, and Valero retains the associated RINs Estimated adjustments to VLO Reduces corporate annual G&A expense by approximately $50 million per year beginning 3Q13 32

Valero's Wholesale Business VLO markets branded and unbranded refined products on a wholesale basis through an extensive rack marketing network The Valero-branded family operates in the U.S., Canada, and U.K. with approximately 1,000 branded sites in the U.K. and Ireland These sites are independently owned and are supplied by Valero under multi-year contracts The principal buyers of our refined products from terminal truck racks are wholesalers, distributors, retailers, and truck-delivered-end users For wholesale branded sites, we promote our Valero (r), Beacon(r), and Shamrock(r) brands in the U.S., Ultramar in Canada, and the Texaco(r) brand in the U.K. and Ireland 33 (CHART)

(CHART) Refining Crude & Feedstock Supply 34 Valero crude and intermediate feedstock runs were approximately 2.3 million bpd in 2012 Valero ran 94 unique crudes in 2012 Crude and intermediate feedstock inventories typically range from 58 to 70 million barrels throughout the year We hedge all crude against LIFO inventory levels to protect against volatile swings in crude price between date of purchase and date of delivery/consumption at the refineries About 75% of Valero's crude oil purchases are under term contracts, and nearly all purchases have market-based pricing Valero receives crude and feedstocks by many modes of transport including tanker ship, barge, pipeline, rail, and truck MBPD

Processing Light Crudes 37 Refineries are designed for a specific range of crude oil properties, otherwise build costs would be very high Lighter crudes contain significantly more light components, e.g., propane, butane, straight run gasoline, naphtha Be careful about generalizing crude oil properties and their impact on product yields Some light crudes are inherently diesel rich or gasoline rich despite having a similar API gravity As we have shifted our diet to higher API domestic shale crudes (Eagle Ford, Bakken, etc.), we have seen distillate yields stay about the same, while gasoline yields have increased Many constraints can limit a refinery's ability to process light components, and constraints are refinery specific Examples include: Distillation tower has insufficient capacity for light components Hydraulic capacity of overhead distillation hardware Heater or heat exchanger design has insufficient capacity, flexibility or limited ability to cool and condense higher volume of light ends Saturated gas plant has insufficient capacity to process additional volume Downstream processing capacity limits ability to convert intermediates into finished products Depending on the constraint, solutions can range from $10 million to hundreds of millions

RINflation! - Expect Consumers to Pay Higher Cost of RFS Mandate 38 Situation RFS mandates a specific volume of renewable fuels to be blended with gasoline and diesel Due to lower annual gasoline demand, the mandated renewable volume exceeds the possible blended volume (E-10 and E-85), creating the "Blend Wall" for gasoline Renewable Identification Numbers (RINs) are used to show compliance with mandate RFS mandate is unfair and favors companies that blend more gasoline and diesel than they produce Impact As industry approaches the Blend Wall, the price of ethanol RINs has increased dramatically from 3 cents per gallon in 2012 to more than $1 per gallon, and have recently traded between $0.60 and $0.80 per gallon Expect higher prices for gasoline and diesel due to flow-through of higher RINs cost and: High RIN prices economically encourage exports and can lower imports of gasoline and diesel Lower imports and higher exports can reduce supplies and cause fuel prices to increase Valero is impacted as a significant spot seller of unblended gasoline Estimated 2013 RFS compliance cost is between $600 million and $800 million based on recent RINs prices and range of volumes depending on obligation, production, exports, and carryovers Recent Developments EPA's announced their intent to adjust the 2014 RFS to a "reasonably attainable" level due to the constraints of the blend wall, lack of market penetration for ethanol blends above E-10, and other market factors Valero eagerly awaits new and meaningful information

The transition of the U.S. refining system to being a net exporter to the world market has mitigated the impact of declining domestic demand Large quantities of U.S. diesel and gasoline exports to Latin America and diesel exports to Europe International demand has been "pulling" products Valero's share of U.S. exports has averaged 20% to 25% over the past few years U.S. Shifted to Net Exporter 56 (CHART) U.S. Demand for Refined Products and Net Trade MMBPD U.S. Petroleum Demand Excluding Ethanol and Non-Refinery NGL's (Refined Product Demand) Net Imports Net Exports Implied Total Production of U.S. Refined Products Note: Implied production = Petroleum demand excluding ethanol and non-refinery NGLs minus product net imports; Source: EIA, Consultant and Valero estimates Implied Production of U.S. Refined Products for Domestic Use

(CHART) U.S. Shifted to Net Exporter Net Imports Net Exports MBPD Diesel net exports remain strong, with U.S. refiners sending a net of 751 MBPD to other countries in 2013 (Jan-Jun). Gasoline net imports have fallen from almost 1MMBPD in 2006, to only 101MBPD in 2013 (Jan-Jun). Still, gasoline and blendstocks are the only product category where the U.S. remains a net importer. As a result of the continued shift towards exports, U.S. net exports of petroleum products have increased from 335 MBPD in 2010 to 1,628 MBPD in 2013. 57 Note: Gasoline represents all finished gasoline plus all blendstocks (including ethanol, MTBE, and other oxygenates) Source: DOE Petroleum Supply Monthly with data as of June 2013. 4 Week Average estimate from Weekly Petroleum Statistics Report and VLO estimates
