Ann: Appendix 4D and Half Year Financial Report, page-26

Exercised Options may be satisfied, at the discretion of the Board, in cash rather than Shares, by payment to the
holder of the cash equivalent value, net of applicable taxes and other withholdings, less any exercise price that
would have been payable by the holder (and no exercise price is required to be paid by the holder).

I don't expect WP to stump up the cash. Imo that's clear by the remuneration and lack of purchase in market.

Also, my average cost is low, so I'm happy to be well in profit though, the market value has a very long way to go.
