(a)
    
    Each option entitles the holder to subscribe for one fully paid ordinary share in the
capital of the Company (Share) upon exercise of the option and payment of the Exercise Price
(defined below).(b)
    
    Each option is exercisable at $0.015 (Exercise Price), payable in full on exercise of the
option.(c)
    
    The options expire at 5.00 pm Australian Eastern Standard Time on 13 September 2013 (Expiry
Date).(d)
    
    The Company must give the holder of each option a certificate or holding statement stating:
 (i)
    
    the number of options issued to each holder;(ii)
    
    the Exercise Price of the options; and(iii)
    
    the date of issue of the options.
 (e)
    
    Holders may exercise options at any time up to the Expiry Date. Any option not exercised,
automatically expires on the Expiry Date.(f)
    
    Options may only be exercised by the delivery to the registered office of the Company or the
share registry of a notice in writing stating the intention of the holder to:
 (i)
    
    exercise all or a specified number of options; and(ii)
    
    pay the Exercise Price in full for the exercise of each such option.
 (g)
    
    The exercise notice must be accompanied by the certificate or holding statement for the
options being exercised and a cheque made payable to the Company for the Exercise Price for
the options being exercised.(h)
    
    The options will be deemed to have been exercised on the date the exercise notice is received
by the Company or the share registry.(i)
    
    The Company will allot the Shares to which a holder is entitled following exercise of options
and deliver a holding statement with respect to such Shares within the timeframe required by
the ASX Listing Rules.(j)
    
    The exercise of only some options will not affect the rights of the holder to the balance of
the options held by them.(k)
    
    If the holder of the options exercises less than the total number of options registered in
the holders name:
 (i)
    
    the holder of the options must surrender its option certificate, if one has been
issued by the Company; and

(ii)
    
    the Company must cancel the certificate and issue the holder of the options a new
certificate or holding statement stating the remaining number of options held by the
holder and stating the information set out in item (d) above.
 (l)
    
    Options will not confer an entitlement to receive dividends declared and paid by the Company,
nor an entitlement to vote at general meetings of the Company unless the holder of the options
has exercised its options before the record date for determining these entitlements and
participates as a result of holding Shares.(m)
    
    All Shares issued on exercise of a option will:
 (i)
    
    rank equally in all respects (including, without limitation, rights relating to
dividends) with other issued Shares;(ii)
    
    be issued credited as fully paid;(iii)
    
    be duly authorised and issued by all necessary corporate action; and(iv)
    
    be allotted and issued free from all liens, charges and encumbrances whether
known about or not including statutory and other pre-emption rights and any transfer
restrictions.
 (n)
    
    The Company will apply to ASX Limited for official quotation of the Shares issued upon
exercise of options within the time period required by the ASX Listing Rules.(o)
    
    The options may be transferred at any time in accordance with the Corporations Act 2001(Cth)
and the ASX Listing Rules.(p)
    
    A holder of options does not have the right to participate in bonus issues or new issues of
securities offered to Shareholders until Shares are allotted to the holder pursuant to the
exercise of the relevant options.(q)
    
    In the event of a reorganisation (including, without limitation, consolidation, sub-division,
reduction or return) of the capital of the Company, the rights of the holders of options
(including, without limitation, the number of options to which the option holder is entitled
to and the exercise price) will be changed (as appropriate) in accordance with the ASX Listing
Rules applying to a reorganisation of capital at the time of the reorganisation.(r)
    
    If the Company makes a pro rata issue (other than a bonus issue) to existing Shareholders and
no Share has been issued in respect of the options before the record date for determining
entitlements to the issue, the Exercise Price of each option will be reduced in the manner
permitted by the ASX Listing Rules applying at the time of the pro rata issue.(s)
    
    If the Company makes a bonus issue to existing Shareholders and no Share has been issued in
respect of a option before the record date for determining entitlements to the issue, then the
number of Shares over which that option is exercisable will be increased in the manner
permitted by the ASX Listing Rules applying at the time of the bonus issue.(t)
    
    The Company is entitled to treat the registered holder of a option as the absolute holder of
that option and is not bound to recognise any equitable or other claim to, or interest in,
that option on the part of any person other than the registered

    promptly pay any amount deducted to the appropriate governmental taxation
authority;(ii)
