16 NuStar’s Reactivation of an Idle 12-inch Pipeline should increase annual EBITDA by $23 million1 Signed long-term agreement with Occidental Petroleum (Oxy) in February 2014. Oxy will ship NGLs on our formerly idle, 200-mile 12-inch pipeline between Mont Belvieu and Corpus Christi  The line has the capacity to transport 110,000 barrels per day  Oxy will utilize the majority of the line’s capacity  NuStar is marketing the remaining pipeline capacity Began generating DCF in the second quarter of 2014 Pipeline projected to be in full service, early in the third quarter of 2015 Capital spending required to reactivate the line expected to be $150 to $170 million 1 – Please see slide 31 for a reconciliation of EBITDA to its most directly comparable GAAP measure

17 Recently Signed Letter of Intent with PMI to Develop Project to Transport LPGs from the U.S. Into Northern Mexico Recently signed non-binding Letter of Intent with PMI Based on development to date, we would hope to establish a joint venture with PMI in early 2015 Early indications are that this project could be completed in the second half of 2016 Laredo PL – 8” Valley PL – 6”/8”/10” Houston – 12”

18 Several Factors Shield NuStar’s Pipeline Revenues From Crude Price Volatility Pipeline revenues system-wide are ~90% committed either by take or pay or through exclusivity1  Typical contract length 3-5 years (5-10 years for new build)  ~95% of our tariffs are FERC-based, which are adjusted annually for inflation Approximately 75% of our pipeline revenues relate to throughput volumes that either supply feedstock materials to refineries/ammonia plants or deliver the produced refined products to local markets  In many instances, NuStar’s pipelines are the only viable options for our customers  Throughput volumes have not historically fluctuated with changes in feedstock and refined product prices The remaining 25% of our pipeline revenues relate to Eagle Ford Shale throughput volumes  Throughput and deficiency (T&D) agreements support the majority of our Eagle Ford revenues  Minimal counterparty risk – customers are large, established and credit worthy  3-8 years remaining on all Eagle Ford contracts  State-of-the-art Corpus dock – competitive advantage for customers looking for an alternative to Houston Pipeline projects scheduled for completion in 2015 will be supported by T&D agreements  Houston 12” – currently 67,000 barrels per day committed, take or pay with a five-year term  Phase 2 of South Texas Crude Oil Pipeline Expansion – currently partially committed, take or pay with a five-year term (and five-year renewal option) 1 – Uncommitted lines serving refinery customers with no competition

19 Continuing to Focus on Other Pipeline Growth Opportunities Currently evaluating: Expansion of our existing South Texas Crude Oil Pipeline System Construction or acquisition of crude oil gathering assets that would supply our South Texas Crude Oil Pipeline System Crude oil and refined product pipeline opportunities in various shale plays Total Pipeline Segment internal growth spending could be in the range of $900 million to $1.1 billion1 1 – capital spending to take place over the next two to three years.

Storage Segment Update

22 Pursuing Other Storage Terminal Opportunities Currently evaluating: Rail car off-loading projects on the West Coast Viability of a Pt. Tupper rail offloading facility for crude oil and/or LPG Additional storage expansion at St. James Terminal Our St. Eustatius Terminal’s role in regional demand for additional crude oil storage and infrastructure capacity Terminal acquisitions in strategic markets Total Storage Segment internal growth spending could be in the range of $100 to $300 million1 1 – capital spending to take place over the next two to three years.

Fuels Marketing Segment Update

We Expect Reduced Working Capital Requirements and Minimized Volatility in the Fuels Marketing Segment 24 Segment is composed of:  Refined Products Marketing  Bunkering  Crude & Fuel Oil Trading A back-to-back supply agreement at our St. Eustatius terminal:  Reduced our working capital by approximately $50 million  Reduction in operating expenses has improved results Fuels Marketing Segment currently pays Storage Segment approximately $25 million in annual storage fees  Represents around 5% of Storage Segment revenues 2014 and 2015 EBITDA results for the segment are expected to be $20 to $30 million1 1 – Please see slide 32 for a reconciliation of EBITDA to its most directly comparable GAAP measure

Management uses these financial measures because they are widely accepted financial indicators used by investors to compare partnership performance. In addition, management believes that these measures provide investors an enhanced perspective of the operating performance of the partnership’s assets and the cash that the business is generating. None of EBITDA from continuing operations, DCF from continuing operations or DCF from continuing operations per unit are intended to represent cash flows from operations for the period, nor are they presented as an alternative to net income or income from continuing operations. They should not be considered in isolation or as substitutes for a measure of performance prepared in accordance with GAAP. For purposes of segment reporting, we do not allocate general and administrative expenses to our reported operating segments because those expenses relate primarily to the overall management at the entity level. Therefore, EBITDA reflected in the segment reconciliations exclude any allocation of general and administrative expenses consistent with our policy for determining segmental operating income, the most directly comparable GAAP measure.
