Ordinary shares Note 1 - Share consolidation 10 to 1, which was approved by shareholders at the Annual General Meeting on November 15, 2017 Note 2 - Shares issued to the Company’s Scientific Advisory Board in return for services Note 3 - Section 258F of the Corporations Act allows a company to reduce its share capital by cancelling any paid-up share capital that is lost or is not represented by available assets. Given the long history of the consolidated entity and changes in the principal activity in recent years, the Directors believe that A$162,223,185 of the parent entity’s share capital satisfies the criteria in Section 258F of the Corporations Act and accordingly this amount of the ordinary share capital has been cancelled.
