Notes:
As advised on 13 August 2013, the Company is seeking Noteholder's approval to amend some terms of the Terms of Issue of the Notes, at a meeting to be held on 13 September 2013. One of the amendments is in relation to calculation of the issue price for shares issued in lieu of cash for interest payments, with the effect that the pricing period be moved to be prior to the interest payment date rather than after the interest payment date as it currently is, otherwise the calculation is unchanged. If these amendments are approved, the resulting shares will be issued on 30 September 2013.
If the amendments are not approved, the interest payment will be calculated in accordance with the existing terms being the lesser of a 10 day volume weighted average price of ordinary shares traded on ASX post the interest payment date discounted by 10%, and $0.11, with the shares to be issued on 17 October 2013.
