71 SO Overfill Prevention Valve CARB Approved 71 SO Vapor-tight Overfill Prevention Valve eliminates the need for messy and timeconsuming 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 5

Compare The Differences Features/ Differences Benefits 71 SO EMCO A 1100 EVR EBW 708 -450 No Epoxy No mess. No curing. Higher quality, easier, more reliable and cost effective installation Yes No No Polypak seal No epoxy. Easier, quicker installation. Improves valve reliability. Reduces maintenance costs. Reduces valve install time by up to 24 hours. Yes No No No epoxy. Eliminates curing issues in hot and cold Straight threaded joint with weather to ensure a higher quality, easier, more O-ring seal reliable EVR compliant installation. Eliminates the mess of epoxy sealants. Yes No No Eliminates 10 of 17 potential leak paths 60% higher level of protection against fugitive emissions and pressure decay to help ensure EVR compliance Yes No No Blind hole taptite screws Eliminates 6 potential leak paths Yes No No Rearranged sealing joints Eliminates 3 potential leak paths Yes No No Rearranged valve poppet location Eliminates 1 potential leak path Yes No No Quality assurance tool Improves installation quality to help ensure EVR compliance Yes No No Patent & Patent-Pending Construction Highest flow rates in the industry Yes No No 6

No Epoxy Before 71 SO § 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 After 71 SO 7

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 17 -20 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 8

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 9
