Great, now that you know what licenses are involved you can read them and figure it out
I don't know shit about EPL, and it's been years since I looked into the LGPL, but as I recall it was reactionary license created out of fear of the viral possibilities of GPL. Odds are you aren't going to be able to straight up sell modifications to that code base. GPL was created to force people to give back their enhancements to the community.
