Krombacher,
Just some simple, rough math (& rounding off to make the numbers easier). ERHC Energy has ~3 billion shares. Let's say TotalEnergies bought all of ERHC's rights, to JDZ and EEZ for $300M. So ERHC would get $0.10/share.
Today, TotalEnergies is trading for ~ $59/share and ERHC is trading for ~0.005/share. So 1 TTE share would equate to 11,800 shares of ERHC. Thus, in your hypothetical, if you had 5 million shares of ERHC, you would get ~423 shares of TTE.
