2. Air Methane Air and Methane Gas enter the cylinder Diesel Engine Gas Injector

3. The Air and Methane gas mixture is compressed

4. As the piston reaches TDC a reduced amount of diesel is injected into the cylinder

5. The air and methane gas mixture combusts as a result of the diesel injection A ir

6. The burnt mixture exits the cylinder as normal on the exhaust stroke

7. o Operate 150+ mixed fleet, major focus on construction o 50%+ fleet utilizing Dual Fuel technology o Introduced Dual Fuel technology to UK in 1998/99 o Hardstaff fleet has completed 62+ million miles to prove the technology and develop reliability o Typical substitution between 50 – 60% o Typical CO2 savings 14 – 18%

8. CNG stored in pressurized cylinder containment LNG stored in cryogenic tank containment

9. Hardstaff OIGI® (Oil-Ignition Gas-Injection) Dual Fuel Vehicle Technology Electronic system that reduces the amount of diesel injected into a cylinder, replacing the fuel with natural gas or bio methane, without affecting power and characteristics of the original diesel engine. o OIGI® Dual Fuel is a patented combustion technology that simultaneously burns two fuels - natural gas or biomethane and diesel. o Sequential gas injection, metered on a cylinder by cylinder basis. o Diesel is required as the ignition source. o The engine will use 100% diesel at idle; gas injection and diesel reduction commences when engine speed increases from idle.

11. The OIGI system uses cylinder by cylinder gas substitution strategy o No change to original engine power or torque o Seamless transition between Diesel and Dual Fuel modes o Improves Driver acceptance o No impact of application of vehicle o Improved fleet integration o Proven reliable system is accepted by a number of OEM’s o Seamless warranty and service provision o No added risk for the operator / owner o Reliable and non-invasive technology platform o Acceptable to fleet managers and technicians o Ease of acceptance by operators, technicians and fleet management enables wider fleet adoption o Highest possible rates of gas substitution o Maximizes reductions in diesel consumption o Maximizes financial and environmental benefits

12. Reduced Legislated Emissions o Cleaner tail pipe emissions is a business differentiator o Drives new business, win contracts with environmentally conscious clients o Inherent reductions in Particulate Matter (PM) o Reduces balance point performance of DPF technologies o Reduces associated service costs o Potential exemption from Low Emission/Congestion area restrictions o May remove the need to install exhaust after treatment Reduced CO2 Emissions and ability to operate using Biomethane o Carbon footprint – a significant business driver within major corporate and governmental customers o Opens doors to new business and meets requirements of existing customers

13. Dual Fuel Substitution Vs CO2 Reduction Reduced CO2 Out Put In Dual Fuel Mode o As substitution rates increase CO2 reductions increases o With average substitution rates of 55%- 65% CO2 output will be reduced by 15% to 18% o 18% to 22% CO2 reductions In regional haul and over the road applications

15. Improves balance point performance of DPF technologies

16. No modifications to original OBD systems o Accepted by OEM’s o No effect on function of whole vehicle systems o Uninterrupted and seamless warranty o Minimal “service time” implications FYDA Energy Solutions is the North American Distributor for the Hardstaff OIGI Technology o FYDA Energy Solutions, Hand Selects it’s Dealers throughout the United States o Service and support from your existing service provider o Maintain single point service o Minimal additional service down time o Sales and service advice from your trusted local expert o Confidence and comfort of the “local feel” of the transition to gas o No Lost sleep

17. Significant reduction in overall running costs o Significant reductions in cents per mile running costs o Fast Payback in fuel intensive operations o Very effective capital investment o Game changing effect on overall fleet running costs o Use savings for strategic business development initiatives o Long term business security in a changing economic climate Combination of Dual Fuel concept and non invasive installation o Easily converted back to conventional diesel o More flexible at point of vehicle resale o No accelerated depreciation of base asset necessary o Around 50% Dual Fuel components recycled to second vehicle o Enables Flexible depreciation options o Spreading depreciation may further enhance business case

18. Capable of higher power ratings than dedicated gas o Single Gas strategy across whole mixed fleet o Develops expertise and best practice Up to 20% greater energy efficiency than dedicated gas o Reduces overall consumption of fuel o Bigger CO2 savings preferable to larger corporations CSR policies Can run on as dedicated diesel o More flexible operation in areas of low re-fuelling infrastructure or unexpected traffic conditions o No vehicle recovery costs if gas supply exhausted Dual Fuel – Altogether Better
