It's possible that the company want to know whether options holders plan to sell on market or hold to expiry.
There are large buy orders in for .005c - It's possible that somebody looking to buy a large volume might want to buy as many options as possible, and exercise them, potentially getting a lower average price than if they bought the whole lot on market - especially if they want to buy more than the total number of options, so will drive the average buy price up further.

Perhaps the company are weighing up extending the options (or offering a very cheap 1 for 1 option as a replacement). If they are going to be underwritten as above, they won't but if people are going to hold after they're off the ASX and hope to see news in the final week then maybe they'll extend.

I told them I'll be holding to expiry and deciding on the expiry date. Although the guy didn't push for info until I asked whether he wanted to know what I planned to do.
