It's not ERHC's rights that are in question....it's who owns them if this goes private...and what they can do with the company. If Offor and friends own 51% they can set the rules. I've seen 51% owners of many private US companies end up with the whole enchalata for next to nothing while the minority owners were still scratching their head wondering what just happened.
Your shares have already been devalued to zilch...and they weren't even private yet. 10 years ago did you ever think that you could be holding shares valued at .0001 or .0002? I doubt it. But now you think you know how this will turn out. I doubt that too.
