In the Longer Term, We are Optimistic That Refined Products Demand Recovery is the First Step on the Road Back to Overall Recovery 11


 
U.S. Refined Products Demand is Expected to Recover to Almost 90% of Pre-COVID Gasoline and Diesel Demand by late 2020, and We Have Already Seen Even Stronger Rebound in the Markets We Serve U.S. Refined Products Demand ★ In the second quarter, refined (as a Percentage of products demand dropped by Pre-COVID Demand) 100% 24% compared to 2Q 2019, but 100% 96% by year-end 2020, gasoline and 86% 88% 89% 90% 91% 90% 82% diesel demand are expected to 76% recover to pre-COVID demand 80% levels of 88% and 90%, 70% respectively 60% ❑ The recovery of jet fuel 50% demand is expected to lag 40% one year behind gasoline and diesel demand, as the airline 30% industry continues to 20% experience low flight activity 10% 0% 1Q20 2Q20 3Q20 4Q20 1Q21 2Q21 3Q21 4Q21 2022 Gasoline Diesel Jet Fuel Total Refined Products Source: Wells Fargo 12

GULF COAST STORAGE & EXPORT We are Exporting Permian Barrels for Trafigura From Our Corpus Christi Facility on Our Expanded South Texas Footprint ★ We have completed our project for Trafigura to connect our existing South Texas Crude System with PAA’s Cactus II to transport Permian barrels to our Corpus Christi North Beach facility for export: ❑ In August 2019, we began transporting WTI via our South Texas system 16” pipeline from a connection to PAA’s Cactus II pipeline to our Corpus Christi North Beach Terminal ❑ In September 2019, we Summer 2020 completed construction on a new 30” pipeline from a connection in Taft, TX to our Corpus Christi North Beach Terminal and in 1H20 we also completed 600Mbbls of storage at Corpus Christi, which has brought our capacity at the facility to 3.9MMbbls ★ Taft, TX is evolving into the point of convergence for all three new pipelines and offers shipper optionality to deliver to either side of the ship channel (Ingleside or Corpus Christi) ❑ In August 2020, we expect to complete a connection to Gray Oak in Taft, and we will continue to evaluate connecting to other pipelines as warranted by the recovering demand and our customers needs 25

GULF COAST STORAGE & EXPORT Our St. James Terminal is a World-class Facility That We Will Continue to Connect and Equip as Demand Grows and the Hub Evolves ★ We are developing projects to ensure that, as in-bound pipeline volumes grow, we have the connectivity and capability those barrels require for handling, storage, blending, batching and export ★ Our facility is evolving into an “outward-facing” platform that provides targeted service: receiving a diverse crude slate and storing, blending and delivering a customized “cocktail” to local, as well as other U.S. and international, destinations, according to our customers’ specific needs ⭐ Bayou Bridge 24” ⭐ Zydeco 18” ⭐ Marathon 30” ⭐ LOCAP 48” ⭐ ExxonMobil 16” & 24” ⭐ ⭐ Crimson 16” Shell Norco 1.5MM BPD* ⭐ Ship Shoal 20” (via LOCAP 30” ⭐ Future: Capline 40” (late 2021) /Maurepas 24”) Pipelines- 3.5MMbpd (+ Capline reversal) Unit Trains- 100Mbpd 9.9MM bbls (expandable +5MMbbls) *Year-end 2020 local refinery connectivity 27


 
GULF COAST STORAGE & EXPORT Our Unit Train Facility Benefits From WCS/Bakken Price Dislocations From Pipeline Constraints PLUS Our Key Connectivity Will Benefit From Export Growth as Those Constraints are Resolved ★ Prior to March, the lack of long-haul pipeline capacity to transport WCS supply to Gulf Coast demand generated price differentials that supported unit train economics ❑ We have contract commitments for 30MBPD through April 2022 ❑ As Canadian production ramps back up, this price dislocation is expected to re-emerge and continue until Enbridge Line 3 is in service, now estimated to occur in 2021-22 ★ We can also handle light Bakken barrels with our rail facility, which may be an attractive alternative to DAPL MBPD Canadian Crude Oil Production Outlook 6,000 Rail Opportunity ★ We continue to work to assure our facility is connected to 5,000 the pipeline projects in progress to debottleneck shale 4,000 plays, the region, as well as the Midwest and beyond ❑ In March 2019, Bayou Bridge began bringing WTI light, 3,000 Bakken and Canadian barrels either for export or local 2,000 use 1,000 ❑ As soon as late-2021, Capline owners plan to reverse its service to bring WTI, heavy Canadian and Bakken 0 crude for use in regional refineries and export to other locations Production Pipeline Takeaway Capacity Source: ESAI 28
