Greetings warvidalI can tell you for certain that all of the purchases showing code "10" would be acquistions in the market place. The price is shown each time. That definitely would be the purchase price.
Now for code 30. This is not the same as a share option plan where a price is determined for execution at a later date, and when the stock price becomes much higher, the exercise of the option takes place at that previously determined price.
This time code 30 shows +67,871 shares at 0.2735 cents for a new balance of 864,105 shares. Perhaps your suggestion is correct and it would appear that the 0.2735 cents is in error because I just checked the charts and I see that the share price was around 22 cents at the end of December 2004.
