Ann: Options Underwriting Over Subscribed-GPH.AX, page-59

I'm still undecided about whether to exercise all or any of my options. They owe me .005 so total buy in would be 8.5c.
It would be 6.25% above what the new holders of the 8c expired options are paying to convert and I would be comfortable with that price although I could of bought heads or options at a slightly cheap price if I had waited a week!
Main concerns are,
Who is taking up the options on expiry (announcement made about sub underwriters sounds good) and will they hold or sell into any news.
Still waiting on flow results.
Holding while options are converted.
