Unless you are vaccinating foals, SafeGuard is likely not doing you much good. More than 90% of areas tested have strongyles that are resistant to fenbendazole (the active ingredient in SafeGuard). It's possible that the Exodus isn't either though resistance to pyrantel isn't as common as to fenbendazole.
