you might want to check they actually have to pay for the options, if you read the notice it seemed to me per some section of the corporation act EN1 could loan them money to buy the options, not sure though... I posted a snippet above. basically they'd lend the staff an amount to pay for the shares at 25%+ of the share price VWAP. anyways, it's not like the confusing nature of this comes as a surprise or is a game changing deal breaker, seems to be EN1's jam, business as usual.
