Ann: Change of Director's Interest Notice, page-13

there really isnt anything to this. whatever the company gave out they get back with the options being exercised.
there is no money loss unless they never get paid back. in which case it would be a "shares lost" not money.

if the director sells the shares then thats a huge red flag. apart from this it could be a stunt for someone exercising the options early to show "confidence".

the only real questions will be, do these shares have full voting rights and can they be sold prior to the loan being repaid. i would guess the answer is yes to both. nothing can be done. if you hate it, use your voting at proposals to show it and email management to voice concerns.
