System Overview Top Level Stainless steel routing LOP Detection Tube Piston Accumulator Detector THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. System Overview Detection Loss Of Pressure (LOP) - Strategically routed throughout the protected compartment. - Bursts or melts at ~375º F opening release valve - Simple pneumatic activation, does not require electricity - Eliminates false activations due to electrical issues - Manual activation option Other Options: - Spot thermal sensors - Linear thermal wire - Manual push button activation - Methane detection THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. System Overview Piston Accumulator - Patented design - 4L (small bus), 6.5L & 7.5L (large bus) systems. Option to gang PA’s together for larger vehicles. - Stores / releases H2O mix - System charged to ~950 PSI and provided continuous flow for 40-70 seconds. - Mounts and works in any orientation, no system orientation concerns (rollover, etc) THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. System Overview Nozzles - Patented spray nozzles deliver 2000 atomized droplets (80 micron) per 1mm droplet - Spray is a 90° coned shape pattern - Water mist flashes to steam and can be indirect to the fire - Nozzle covers to prevent contamination THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. System Overview Assembly / Mounting Options - Piston accumulator can mount in any orientation allowing for more mounting options than powder systems. - 6 inch diameter allows for tight space clams. - Alarm panel monitors system pressures and controls engine shutdown. - Optional fire button allows for manual deploy.

Benefits Proven Technology - 70,000+ systems installed worldwide - Fogmaker is the leading fire suppression supplier in the European and Australian bus market. Fogmaker is the preferred system for Mercedes & Volvo in Europe. - UK overview: Total fleet of ~600 with Fogmaker, 33 known incidents over 4 years with all being suppressed without issue and minimal damage. - Australia, we have installed well over 1000+ Government Buses with Fogmaker and we have to date had approximately a dozen thermal events with buses fitted with the System. In all cases, the system has detected & suppressed the fires with little or no damage with exception to “what” caused the initial fire (ie cracked fuel rail, electrical arcing, broken lines / hoses, debris etc.) - Over 1000 buses in US and Canada are now using Fogmaker – UL Listing was requested by some larger customers. - CNG application in Tempe with NFI, very happy to date and positive result on incident THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. Benefits UL Listing update • Officially listed UL product as captured under listing for Fogmaker NA • Listing is per UL Subject 1384 • Testing consists of system level detection / suppression testing as well as multiple component level tests (over 100 total tests in all) • Only system UL approved for ‘self-contained automatic extinguisher units’ as other approvals relate to total flooding and do not cover complete automatic detection systems • Listing can be found at www.UL.com THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. Benefits SBF128 - Testing method was that of SBF128 (Full-scale extinguishing trials of water mist in a bus fire) - SBF128 is a Swedish test protocol executed by SP (Science Partners) and tied to the Insurance Institute - Overview of the test - 20 min preheat of bus (15 @ idle, 5 with throttle) - 7 pounds of woodchips presoaked for 24 hours with a diesel / oil mixture placed throughout engine - Cotton rags presoaked with above mixture also placed throughout - 1.5 liters of Diesel / oil sprayed throughout - Ignite engine compartment with torch - Close and burn for 20 seconds - Manual activation of the fire suppression system - Continue to run engine / fan at idle speed THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. SBF 128 Test protocol THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. Benefits Performance - Attacks all 3 elements of the fire triangle: - Heat: Water mist cooling effect. - Fuel: AFFF (Foam) blankets the fuel - Oxygen: Steam chokes out the oxygen - Longer cooling & suppressing time - 40-70 seconds continuous - Re-flash prevention -Hot surfaces are cooled below flash temps -Any remaining fuel is covered by the AFFF (Foam) THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. Benefits Environmental - No hazmat required - Fast easy clean-up - Not harmful to people - Not harmful to equipment - Water mist THE INFORMATION CONTAINED OR DESCRIBED IN THIS DOCUMENT IS PROPRIETARY TO USSC GROUP, AND MAY NOT BE REPRODUCED, DIVULGED OR USED WITHOUT WRITTEN PERMISSION FROM USSC GROUP. Benefits False Activations / Clean-up - LOP requires no electricity or operator involvement thus reducing false activations due to electrical shorts & operator error. - Clean-up is fast and only requires pressure washing of protected area. - PA & detector can be recharged in vehicle or exchanged for an in-stock replacement. - The system can be recharged in under 1 hour by trained personnel on site.
