expands the sales of its commercial gas purification systems. The term loan will
principally be used to finance capital investments, including manufacturing
equipment required to commercialize the large capacity hydrogen purification
system that QuestAir is developing in conjunction with ExxonMobil Research and
Engineering Company.
