[completely uninformed guess]
I suspect these are just intermediary files generated when compiling. But if they are actually using the extensions in their commonly accepted meaning, then:
DBM files are files containing key/value pairs, used by perl for loading/saving arrays & data structures. If that's what DBP is calling a DBM, then that would be rather cool. But in this case it's more likely to just stand for something like "Dark Basic Media" or something.
EXB are "flash image" files: drive images that can be written to flash drives I think. Not sure how this would be relevant, which is why I reckon it's just an intermediary step to making the .EXE.
