ENERGY RECOVERY SNAPSHOT Page 3 What We Do An energy solutions provider and technology leader in applying fluid dynamics and advanced materials science Pressure Energy is our Arbitrage Who We Are  Create markets to preserve or eliminate pumps that are subject to and destroyed by hostile process fluids  Convert wasted pressure energy into a reusable asset Core End-Markets WATER OIL & GAS CHEMICALS

 
Page 4 VORTEQ COMMERCIALIZATION UPDATE o VorTeq private testing deemed highly successful  Tested all 12 PXs individually up to 8.5 barrels per minute each at 9000 psi clean (no proppant)  Achieved long duration runs in excess of 60 bpm at 9000 psi clean  Pumped a total of 100,000 pounds of proppant throughout testing at up to 64 bpm  Culminated in a 33 minute continuous run at up to 2.4 pounds per gallon of sand and rates up to 64 bpm, equating to 87,000 pounds of proppant delivery to simulated wellbore without VorTeq system failure  Choke and dissipation system erosion precluded achievement of full pressure and run was predominantly in a range of 6800 psi to 7200 psi;  Choke and dissipation system is to simulate well conditions as part of test apparatus, not VorTeq system; enhanced design will be used at license partner facility test o Continue to expect milestone success in 2017

 
Page 5 VORTEQ – A MATTER OF ENGINEERING NOT PHYSICS o System excitation (vibration / shaking) at elevated flow rates was primary failure mode – resulting in:  Axial bearing failure – increase in friction, cartridge rotation impeded  PX cartridge liftoff – PX not seated flush / correctly within housing, increase in friction, cartridge rotation impeded  Radial bearing failure – sand enters radial channel, increase in friction, cartridge rotation impeded  Carbide fracture – cracks in carbide, increase in friction, cartridge rotation impeded o Design enhancements to mitigate failure modes  New Missile Design – Caterpillar Kemper designed manifold: System excitation addressed via modal & harmonic analysis on entire manifold  New Cartridge Design: Bearing failure addressed through hybrid bearing with optimized hydrostatic and secondary hydrodynamic features  New Housing: Cartridge liftoff addressed mechanically and hydraulically (bolted-down and force- balanced)  New Carbide Grade: addresses carbide fracture through use of grade with greater ductility o Computational and Experiential Design Process  Over 17,500 man-hours consisting of 5 PhDs and multiple masters and bachelor degreed engineers  Engineering Disciplines employed – fluid dynamics, fluid-structural interaction, structural dynamics, rotor dynamics, fracture mechanics, tribology
