There's different kinds of "moving away".
For example, if ERHC received hundreds of millions of dollars of compensation for block 4, as a hypothetical example, plus let's say it also either exercised its 15% option or got some form of "upside" as it did from block 11 in the Kosmos deal, then ERHC has indeed "moved away" (and has allowed Shell to move in)... but it hasn't completely moved away in the sense that you mean ... since that upside from oil could certainly serve as dividend material.
But "moved away" would mean that erhc used those hundreds of millions to buy up oil properties all across Africa, like we seem to see in Madagascar with its alliance with Petromad.
And, therefore, could've made itself into acquisition material like a Cove Energy.... after all, didn't Cove have some Madagascar property too?
