dividend, page-11

If you keep your options
(by the way they expire 31/10/08 - ie about 10 weeks and if you don't exercise them you loose your doe)
then the exercise price AUD.277 will be reduced by the same amount as the capital return to shareholders. This is an ASX rule.
Its a no brainer though as, if you exercise them before the record date (yet to be announced but indicated to be about 15 Sept) then you get BOTH the return of capital PLUS the unfranked dividend.
Hope this helps and read tonights announcement to ASX as it gives you all the info you need to exercise them.
