"Further Attaching Options

The further Attaching Options issued upon the exercise of the New Options will not be issued to holders of New Options until such time as the Company has prepared a disclosure document for the purposes of complying with the technical requirements of the Corporations Act in respect of the grant of these subsequent Attaching Options.
Although the Company retains the discretion to issue the disclosure document earlier, the Company may not issue such a document until such time as all New Options have either been exercised or expired.
For clarity, the Attaching Options issued upon the exercise of the New Options will not be able to be transferred or exercised until such time as they are issued."
