All forward-looking statements included in this presentation are subject to certain risks and uncertainties, which could cause actual results to differ materially from those projected in the forward-looking statements, as disclosed from time to time in our reports on Forms 10-K, 10-Q, and 8-K as well as in our Annual Reports to Stockholders and, if necessary, updated in our quarterly reports on Form 10 Q or in other filings. We assume no obligation to update any such forward-looking statements. It is important to note that our actual results could differ materially from the results set forth or implied by our forward-looking statements. FORWARD LOOKING STATEMENT Page 2


 
Page 3 VORTEQ UPDATE o Significant internal lab testing on harder-grade components • Performed 9600 psi, 45,000 lbs proppant test on single cartridge with one end cover in harder-grade and one end cover in softer-grade • Harder-grade performed as expected showing no signs of material degradation • Softer-grade showed degradation consistent with observations made during December field testing Harder grade showed no signs of material degradation despite being on the high-pressure out or “dirty” side of the PX Softer grade showed similar material degradation as witnessed in December field testing


 
Page 4 VORTEQ UPDATE - CONTINUED o Based on internal testing, Company opts to utilize harder-grade for all cartridge components o Cartridge components have arrived and will continue to arrive throughout Q1; timing consistent with prior guidance o Final machining and qualification of received components to continue in parallel o Expect to resume field testing, up to and including milestone one, as soon as all components have been received and qualified o Next update will occur during conference call to discuss year-end results


 
ENERGY RECOVERY SNAPSHOT Page 5 What We Do/Product Strategy An energy solutions provider and technology leader in applying fluid dynamics and advanced materials science 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 Pressure Energy is our Arbitrage


 
MATERIAL SCIENCE ARBITRAGE – PUMP PRESERVATION Page 6 Typical pumps present design and material composition challenges:  Multiple moving parts, multiple potential points of failure  Components chiefly comprised of alloys, coated alloys and polymers Susceptible to abrasion, erosion, fatigue and corrosion The pressure exchanger is elegant in design and robust in material composition:  One moving part (rotor)  Components are cermet or ceramic (tungsten carbide or alumina)  Hybrid bearing technology (hydrostatic and hydrodynamic) Design and Material Science Superiority Yields:  Increased life expectancy  Increased reliability  Lower R&M expenses  Lower CAPEX (less required redundancy) Pressure Exchanger Advantage Status Quo Challenge Value Arbitrage


 
PRESSURE ENERGY RECYCLING - CONVERT WASTED PRESSURE TO ELECTRICITY Page 7 Pressure energy is being needlessly wasted:  Dissipation of energy through valves, chokes or geological mass wastes valuable energy  Wasted pressure energy = wasted electricity and $$$ We recycle otherwise wasted pressure energy:  Pressure energy can be recovered and utilized to pressurize other fluids or create electricity  Our energy recovery devices are capable of transferring up to 99% of a stream’s pressure energy Pressure Energy Recycling Yields:  Less specific energy consumed  Less pumping capacity required  Increased process reliability Pressure Exchanger Advantage Status Quo Challenge Value Arbitrage

PUMP PRESERVATION – PRESSURE PUMPING Page 9 Status Quo With VorTeq NO SAND OR CHEMICALS ENTER THE PUMPS


 
PUMP PRESERVATION – VORTEQ CREATES SIGNIFICANT VALUE Page 10 Existing Pumping Model with 15 to 20 PD Pumps New Pumping Model with 3 to 4 Centrifugal Pumps Centrifugal Pump Model $8M to $12M p/yr p/fleet* Reduced Maintenance: $3M to $4M p/yr p/fleet* Decreased Pump Redundancy / Lower CAPEX: $1M to $2M p/yr p/fleet* With VorTeq Status Quo Centrifugal Pump Model 1 2 3 *ERI estimates


 
Page 11 VORTEQ COMMERCIALIZATION PATH  Commercialization is twofold:  Schlumberger Licensing Agreement • Acceptance standards inclusive of M1 & M2 as well as other performance tests • SLB responsible for missile manufacturing, ERII to provide PXs, housing and motors • Five years from first unit to full deployment of SLB fleet • $1.5MM per VorTeq per year  Liberty has rights for up to 20 VorTeq units • ERII provides full missile and cartridges – vendors have been qualified • Pricing based on contractual ROIC • Performance standards differ and thus speed to market may be faster


 
PUMP PRESERVATION – MTEQ MUD PUMPING SOLUTION Page 12 Status Quo With MTeq NO MUD PASSES THROUGH THE PUMPS


 
PUMP PRESERVATION – MTEQ UNLOCKS VALUE FOR OPERATORS Page 13 Drilling Configuration with MTeq & Centrifugal Pumps Reduced Operating Cost  Reduced R&M  Increased pump life  Fewer pumps Reduced Logistics  Lower load requirements  Less rig-up and rig-down time Increased Productivity  Reduction in planned and unplanned rig downtime Higher Reliability & Safety  Less risk of injury SAVINGS UP TO $600K PER RIG PER ANNUM* *ERI estimates


 
PRESSURE ENERGY RECYCLING – DESALINATION Page 14 Status Quo With Pressure Exchanger  From first sale to 90% market share in under 10 years*  18,000 PX devices installed worldwide  Up to 25-year life with virtually no maintenance  60%+ gross margins Wasted Pressure Energy Toward Geologic Mass 60% reduction in size and subsequent energy reduction Dominating the Energy Recycling Market in Desalination – Our First Market Disrupted Investment Highlights *MPD market share only


 
INDUSTRY AGNOSTIC R&D ALLOCATION PROCESS Page 15 What criteria qualifies a market opportunity?  High rates of flow  High pressure differentials  High capital intensity  Hostile process fluids Fracing Upstream Drilling Desalination
