Q3 FINANCIAL UPDATE Page 3
Q3 STRATEGIC AND COMMERCIAL UPDATE o Water Update . All segments of water business remain strong Robust backlog and pipeline driving positive 2019 outlook Pressure exchanger remains desalination’s premier energy recovery technology . Market activity and trends leading to longer-term optimism Currently pursuing organic and inorganic growth initiatives Seeking to leverage our distribution channel by increasing scope of supply o Oil & Gas Update . VorTeq Focusing on shortening the timeline to full-scale commercialization Accelerated several system-level enhancements and pre-commercialization efforts in advance of M1 - originally planned post M1 Increasing our internal testing capabilities Goal to develop independent full-scale testing facility Greater autonomy permits Company to frequently test design iterations on Company’s schedule without reliance on third parties and further shortens development cycle time . MTeq Successfully completed Round 2 testing Validated ability to run drilling fluid through system under simulated real world conditions More extensive round of endurance testing to be scheduled Page 4
ENERGY RECOVERY SNAPSHOT Who We Are An energy solutions provider and technology leader in applying fluid dynamics and advanced materials science Pressure Energy is our Arbitrage What We Do/Product Strategy . Preserve or eliminate pumps that are subject to and destroyed by hostile process fluids . Convert wasted pressure energy into a reusable asset Page 5
ENERGY RECOVERY: PAST, PRESENT AND FUTURE Present: Future: 1992 - 2014 2015 - 2017 Near-Term Strategy Long-Term Strategy Developed Signed 15-year Grow and Continued Pressure VorTeq license, expand existing market Exchanger commenced market presence leadership & Technology collaborative in SWRO growth in core testing with SLB desalination water business and Liberty Invested in R&D Expand water Commercialization MTeq business in of VorTeq Established solution desalination Market launched, and beyond Leadership completed in SWRO initial testing Further Commercialization development of MTeq Increased Computational of VorTeq shipments Analytics of ERDs practice Worldwide developed, Continuous significant Further innovation of investment development Most core PX of MTeq successful technology for IPO in 2008 Strategic use in new partnership with applications Duchting Pumpen Page 6

VORTEQ FOR PRESSURE PUMPING Status Quo With VorTeq NO SAND OR CHEMICALS ENTER THE PUMPS Page 13
VORTEQ CREATES SIGNIFICANT VALUE Status Quo With VorTeq Centrifugal Pump Model Existing Pumping Model New Pumping Model with 4 to 5 with 15 to 20 PD Pumps Centrifugal Pumps 1 Reduced Maintenance: 3 Centrifugal Pump Model $3M to $4M p/yr p/fleet* $8M to $12M p/yr p/fleet* 2 Decreased Pump Redundancy / Lower CAPEX: $1M to $2M p/yr p/fleet* *ERI estimates Page 14
VORTEQ AGREEMENT & COMMERCIALIZATION PATH o VorTeq Commercialization is twofold: . ERII entered into a license agreement with Schlumberger Technology Corporation – one of the industry’s most respected oil-field services companies Exclusive rights to ERII’s VorTeq for on-shore hydraulic fracturing Upfront $75M exclusivity fee Two separate $25M milestone payments (for a total of $50M) subject to certain KPI’s • Milestone 1: Frac at product licensee test facility • Milestone 2: Frac on E&P well Commercialization Highlights: Acceptance standards inclusive of M1 & M2 as well as other performance tests Product licensee responsible for missile manufacturing, ERII provides PXs, housing and motors Five years from first unit to full deployment in product licensee fleets $1.5MM per VorTeq per year . Liberty Oilfield Services carve-out (ERII’s early-stage test partner) Rights for up to 20 VorTeq units for up to 5 years ERII provides full missile and cartridges – vendors have been qualified Commercialization standards differ and thus speed to market may be faster Pricing based on contractual ROIC Page 15
MTEQ MUD PUMPING SOLUTION Status Quo With MTeq NO MUD PASSES THROUGH THE PUMPS Page 16
MTEQ UNLOCKS VALUE FOR OPERATORS Drilling Configuration with MTeq & Centrifugal Pumps Reduced Logistics Increased Productivity Lower load requirements Less rig-up and rig-down Reduction in planned and time unplanned rig downtime Reduced Operating Cost Higher Reliability & Safety Reduced R&M Increased pump life Less risk of injury Fewer pumps SAVINGS UP TO $600K PER RIG PER ANNUM* *ERI estimates Page 17
