No it's not. 100% correct, that is. You posted:
"They paid 4.8c and if the oppies would of been tradeable on market for 2.5c and they sold,effectively they would of only paid 2.3c."
There is one oppie for every two shares. Therefore, if the oppies were worth 2.5c and they sold them, they would only have paid 4.8c - 2.5c/2 or 3.65c/share.
Simple arithmetic.
