…We Will Continue to Make Safe, Responsible and Efficient Operations NuStar’s #1 Priority… Our safety statistics reflect our commitment to safe, responsible operations  In 2018, as in years past, our safety statistics were substantially better than our peers ➢ 23 times better than the Bureau of Labor Statistics (BLS) comparison data for the Bulk Terminals Industry ➢ 8 times better than the BLS data for the Pipeline Transportation Industry NuStar has received the International Liquids Terminals Association’s (ILTA) Safety Excellence Award 10 times  ILTA reviews its members’ safety reports filed with OSHA, and recognizes member companies that achieve exemplary safety statistics with an award We participate in the OSHA Voluntary Protection Program (VPP), which promotes effective worksite safety and health  Achieving VPP Star Status requires rigorous OSHA review and audit, and Star Status requires renewal every three years  80% of our U.S. terminals are VPP-certified 27

… And We Will Remain Committed to our Employees and our Communities Across North America NuStar has been recognized with numerous awards for its strong corporate culture NuStar employees contributed 90,000 volunteer hours in 2018 alone  NuStar maintains local volunteer councils in each community in which we operate to contribute to the charitable and civic causes unique to that local community 100% of our U.S. employees contribute to our United Way campaign, and our average per capita contribution is the highest in the nation for a company our size  In total, NuStar contributed $3 million in 2018 Each year since 2007, NuStar’s employees have hosted a golf tournament to support Haven for Hope, a transformational campus in San Antonio that addresses homelessness  During those 13 years, the tournament has generated over $42 million for Haven for Hope 28

Appendix Continued Improvement: Our 2019 Plan

Producers in the Basin Remain Bullish on Permian Growth, Strength & Resiliency “When we first described the cadence over the next “The 2019 drilling programs should exhibit a significant two years, we described 2020 as production numbers productivity increase versus 2018 program. Wider spacing that translated into double-digit production growth is expected to drive significant productivity improvements with oil production outpacing the overall growth versus offset tighter space packages through our acreage.” where we saw free cash flow at $50 oil and where we saw free cash flow approaching $1 billion at $60 oil. And that's still what we see today under that same “We went through a period, where we did a lot of testing base budget scenario.” and slowed down and make sure we get spacing, right, understood gas-oil ratios, where we could move forward and you're seeing the results of those programs.” “It's our acreage position that allows us to prioritize returns and capital efficiency rather than artificially increasing our inventory through tight well spacing, “We expected to generate a productivity uplift with our which, as we know, increases your exposure to the 2019 action plan and we are seeing that borne out in the parent-child impacts. It's this development strategy, early data.” combined with advances in our completions “We are guiding to oil production of 87,000 to 90,000 methodology over time, is what has allowed us to barrels per day representing 2% sequential growth at the improve well productivity year-over-year.” midpoint.
