To elaborate a little bit more:
Considering that the hugely redacted TOTAL agreement was entered into just a few days before the Kosmos lawsuit went to trial, I'm inclined to believe that TOTAL entered into that agreement not to make ERHC wealthy, but rather to keep Kosmos from getting a foot in the door. Kosmos probably would have prevailed in court against ERHC, but now TOTAL has been able to keep the door shut to BOTH Kosmos and ERHC. Once the option ERHC has with STP expires TOTAL can step in and deal directly with STP and cut ERHC out of the picture.
It's also quite possible that TOTAL encouraged STP to put the block up seeking interested parties so they would know what kind of competition they may have for the block...
I would expect similar tactics with the JDZ: ERHC will be cut off and shrivel up and blow away.
