1 Leading the Way in Next Generation Overfill Prevention Innovation

2 We Listened to What You Want in An Overfill Valve…  Same high quality construction and features of the industry- standard 61SO  Easier, quicker installation  Reliable, high-level of protection against fugitive emissions  Reduced maintenance expenses  Faster flow rates  CARB certification

3 …And To What You Don’t Want:  No Epoxy  No Mess  No Curing Time  No Delays  No Return Installations  No Downtime  No Pressure Decay Failures  No Fugitive Emissions

4 Introducing

5 71SO Overfill Prevention Valve CARB Approved 71SO Vapor-tight Overfill Prevention Valve eliminates the need for messy and time- consuming epoxy sealants which: Eliminates curing issues in hot and cold weather Makes installation easier and quicker Improves the quality and reliability of installations to ensure EVR compliance Eliminates the need for return maintenance visits to re-epoxy valves, reducing costs

6 Compare The Differences Features/ Differences Benefits 71SO EMCO A1100EVR EBW No Epoxy No mess. No curing. Higher quality, easier, more reliable and cost effective installation YesNo Polypak seal No epoxy. Easier, quicker installation. Improves valve reliability. Reduces maintenance costs. Reduces valve install time by up to 24 hours. YesNo Straight threaded joint with O-ring seal No epoxy. Eliminates curing issues in hot and cold weather to ensure a higher quality, easier, more reliable EVR compliant installation. Eliminates the mess of epoxy sealants. YesNo Eliminates 10 of 17 potential leak paths 60% higher level of protection against fugitive emissions and pressure decay to help ensure EVR compliance YesNo Blind hole taptite screwsEliminates 6 potential leak paths YesNo Rearranged sealing jointsEliminates 3 potential leak paths YesNo Rearranged valve poppet location Eliminates 1 potential leak path YesNo Quality assurance tool Improves installation quality to help ensure EVR compliance YesNo Patent & Patent-Pending Construction Highest flow rates in the industry YesNo

7 No Epoxy  The only vapor-tight overfill valve in the industry that does not require messy, time consuming epoxy sealants  Quicker, easier installation  Reduces installation time and costs  Improves quality of installation by eliminating installer sealing errors  Eliminates curing time and need for contractor to return the next day  Improves valve EVR compliance reliability Before 71SO After 71SO

8 Higher Protection Against Vapor Leaks  Special patented and patent pending design features enable improved EVR compliance by eliminating 10 of 17 potential leak paths Typical valves have potential leak paths Higher level of protection against fugitive emissions and pressure decay Improves EVR compliance assurance by 60% Reduces/eliminates future maintenance and/or valve replacement costs  Blind holes taptite screws Eliminates 6 potential leak paths Eliminates need for messy epoxy sealants  Rearranged sealing joints in valve mechanism Eliminates 3 potential leak paths Eliminates need for messy epoxy sealants  Rearranged valve poppet location Eliminates 1 potential leak path

9 Higher Quality Installation  More robust patent/patent-pending design Reduces installation time and costs Improves quality of installation  Polypak seal Eliminates need for messy, time consuming epoxy sealants Reduces installation time by up to 24 hours enabling site to be operational faster Reduces contractor project costs  Straight threaded joint with diametric O-ring seal Superior vapor-tight sealing over tapered thread joint with epoxy Eliminates need for messy, time consuming epoxy sealants to improve quality of installation  Special inlet tube alignment tool Ensures easy alignment for drilling
