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

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

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
