Today s Topics of Discussion Company Overview A little bit about Crestwood Basin Overview on Current and Future Capacity (The Permian Play) Current Y-Grade production out of the Permian Where are we going by 2020? Everyone is hedging their bets. Can t talk about Y-Grade without talking about Plant Expansions and Oil forecast Who are the Players in the Midstream and what are they up to? Existing Capacity and New Y-Grade expansion projects All roads lead to Mt. Belvieu Existing Players expansions in the works and announced NGL Production Impact Factors Discuss pricing of NGL components and their relationship to Crude/Condensate Discuss the heart of the issue All commodity prices are low Frac-Spread- Process by necessity Summary Why are producers drilling in this environment? Discuss what the future may hold 3

Where the Experts say we are now The Experts EIA, Platts, Harts, Bentek, TP, RBN (My favorite), DLH Crude coming out of the Basin 1.7 MMBD-2.1 MMBD, depending on who your Expert of choice is (Lag) Why does Crude Matter? Where there is new Crude, there is rich gas associated with it that needs processing Y-Grade coming out of the Basin 430-480 MBD, depending on your Expert of choice (Lag) Natural Gas 5.9-6.3 BCF/d also depending on your Expert of choice (Lag) Approximately 1.5 BCFD is legacy gas that is on dry lines not going to plants Processing Capacity 4.5 BCF/d and growing rapidly and the 4.5 BCF per day did not take into account Western/Nuevo and some producer owned facilities in the basin Average GPM is 4.8 across the Permian Y-Grade take away Adequate for now most experts agree Some infrastructure needs but they are small Source: Zillow 11

Expert Predictions through 2020-NGL s The Experts are Hedging their Bets EIA, Platts, Harts, Bentek, TP, RBN (My favorite), DLH Crude/Y-Grade/Natural Gas coming out of the Basin Predictions are based on similar cases Crude price is the driver for now Case 1 Growth Scenario* Crude average $56/bbl through 2015 and make their way to $80/bbl by 2017 and make it to $95/bbl by 2020 Case 2 Cutback Scenario* Crude averages $56/bbl for 2015 and make their way to $70/bbl by 2020 Case 3 Curtailment Scenario* Crude stays below $50 on average in 2015 and only reaches $65/bbl by 2020 No one knows which one is right Just forecasts for each case All use roughly the same metrics First lets look at what we thought this time last year.. Basically, in a nut shell, 100 dollar crude for 70 years *RBN Case Source: Zillow 12

What we thought our world would look like in 2014 By 2020: Gas was expected to reach over 8 Bcf/d NGLs were expected to approach 1 MMBls/d Source: RBN Energy 13

Texas Express, although some of its capacity has Permian Y-Grade on it also has a large Eagle Ford component. Oneok purchased Chevron s interest in the West Texas LPG line in late 2014 which serves the Permian and the Barnett. Oneok has indicated that it may expand the West Texas line, however such has not been formally announced.

Summary Y-Grade and Processing Infrastructure Appear to be in-line with current environment Fractionation, which will be discussed later, appears to be in-line with today s market conditions as well The Y-Grade take away players and Midstream providers each have an incentive to adapt quickly to changing market conditions Price uncertainty Some producers will drill to hold acreage even if economics are not acceptable Regardless, if commodity prices remain depressed, drilling will slow and oil, gas and Y-Grade outputs will fall Frac-Spread In most areas, depending on a producers contract with its Midstream provider, someone is losing money as the frac-spread has disappeared Propane The US is now the world s largest exporter of Propane. Propane is now under water in most areas as an NGL Despite being the world s largest Propane exporter, US supply is at record levels with no demand growth The remainder of 2105 should be very interesting Investor Slides for the projects we discussed are attached Source: Zillow 21
