Annexure C Underwriter Option Terms

(a) The Underwriter Options will be exercisable at an exercise price of $0.20.

(b) The Underwriter Options will vest immediately on issue, and will expire at 5.00pm (Melbourne, Australia time) on the date which is 3 years after the date of issue. Any Options not exercised prior to the expiry date will automatically expire at this time.

(c) Each Underwriter Option entitles the holder to subscribe for one CHESS depositary interest over a fully paid share in the Company (CDI) upon exercise of that Underwriter Option.

(d) The Underwriter Options may be exercised in tranches of any number and at any time, as the Underwriter in its absolute discretion sees fit, by written notice by the holder to the Company specifying the number of Options being exercised and in such other form as specified by the Company from time to time (Exercise Notice) and payment of the exercise price for each Underwriter Option.

(e) An Exercise Notice is only effective when the Company has received the full amount of the Exercise Price in cleared funds.

(f) The Underwriter Options may not be exercised by or for the account or benefit of any U.S. Person unless registered under the U.S. Securities Act or an exemption from such registration is available. If the optionholder is unable to certify that it is not a U.S. Person at the time of exercise, the exercise of the Underwriter Option will only be permitted upon the delivery to the Company of an opinion of United States legal counsel that is reasonably acceptable to the Company to the effect that the Underwriter Options and the underlying CDIs have been registered under the U.S. Securities Act or are exempt from registration thereunder. The optionholder must notify subsequent transferees of the exercise restrictions set forth herein.

(g) Within 3 Business Days after the date on which an exercise notice takes effect, the Company must issue to the holder the CDIs to be issued on exercise of the Underwriter Options.

(h) Each certificate representing the the Underwriter Options and CDIs issued on exercise of the Underwriter Options or underlying shares (as applicable) will bear the following legend:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN, AND WILL NOT BE, REGISTERED UNDER THE US SECURITIES ACT OF 1933, AS AMENDED (THE “US SECURITIES ACT”) OR ANY SECURITIES ACTS OF ANY STATE OF THE UNITED STATES (THE “STATE ACTS”). THE SHARES ARE “RESTRICTED SECURITIES” AS DEFINED UNDER RULE 144(A)(3) UNDER THE US SECURITIES ACT AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED, DIRECTLY OR INDIRECTLY, WITHIN, INTO OR FROM THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, US PERSONS (AS DEFINED IN REGULATION S UNDER THE US SECURITIES ACT (“REGULATION S”)) EXCEPT IF SUCH TRANSFER IS EFFECTED (1) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULES 901 THROUGH 905 (INCLUDING THE PRELIMINARY NOTES) OF REGULATION S UNDER THE US SECURITIES ACT, (2) PURSUANT TO AN EFFECTIVE REGISTRATION UNDER THE US SECURITIES ACT AND ANY APPLICABLE STATE ACTS, OR (3) PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE US SECURITIES ACT (WHICH THE COMPANY IS UNDER NO OBLIGATION TO DO), IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE US FEDERAL AND STATE SECURITIES LAWS AND IN THE CASE OF (3) AN OPINION OF COUNSEL SHALL BE DELIVERED TO THE COMPANY (AND UPON WHICH THE COMPANY MAY RELY) REGARDING THE AVAILABILITY OF SUCH EXEMPTION. ANY OPTIONS REPRESENTED HEREBY MAY NOT BE EXERCISED BY OR FOR THE ACCOUNT OR BENEFIT OF ANY US PERSON UNLESS REGISTERED UNDER THE US SECURITIES ACT OR AN APPLICABLE EXEMPTION FROM SUCH REGISTRATION REQUIREMENT IS AVAILABLE. HEDGING TRANSACTIONS INVOLVING THE COMMON STOCK OF THE COMPANY MAY NOT BE CONDUCTED, DIRECTLY OR INDIRECTLY, UNLESS IN COMPLIANCE WITH THE US SECURITIES ACT. THE COMPANY IS REQUIRED BY UNITED STATES SECURITIES LAWS TO REFUSE TO REGISTER ANY TRANSFER OF SHARES NOT MADE IN ACCORDANCE WITH THE ABOVE RESTRICTIONS.”

Underwriting Agreement Page 42

(i) CDIs issued on exercise of the Underwriter Options rank equally with the then issued CDIs of the Company. A CDI issued on exercise of an Underwriter Option is only entitled to receive a dividend where the Underwriter Option has been exercised and the CDI is issued on or before the record date for that dividend.

(j) The Company will issue the Underwriter Options under the Prospectus and make an application to ASX for quotation of the Underwriter Options and comply with any on-sale disclosure requirements regarding the Underwriter Options within 3 Business Days of the issue of the Underwriter Options.

(k) The issue of Options is not conditional on ASX granting quotation of the Underwriter Options. If ASX does not grant quotation of the Underwriter Options, the Company will have issued the Underwriter Options on the proposed issue date on an unquoted basis.

(l) Once quoted on ASX, the Underwriter Options may be transferred at any time by the holder subject to the FOR Facility and in accordance with all applicable securities laws of any state or other jurisdiction of the United States, including any restrictions applicable to the holder resulting from the holder’s status as an “affiliate” of the Company within the meaning of Rule 405 under the U.S. Securities Act. The Underwriter Options and the CDIs have not been registered under the U.S. Securities Act, and may not be offered, sold, pledged or otherwise transferred except in accordance with Regulation S, pursuant to registration under the U.S. Securities Act or pursuant to an available exemption from registration. The holder of Underwriter Options must notify subsequent transferees of the transfer restrictions set forth herein.

(m) The number of CDIs to be delivered in respect of each Underwriter Option or the amount payable, if any, by the holder in respect of CDIs to be delivered to the holder will be reorganised in accordance with the Listing Rules as applicable to Underwriter Options at the time of any such reorganization (if the Company is listed on the ASX), or otherwise as determined by the Board.

(n) In the event the Company proceeds with a pro rata issue (except a bonus issue) of securities to UBI securityholders after the date of issue of the Underwriter Options, the exercise price of the Underwriter Options may be reduced in accordance with the formula set out in the ASX Listing Rules from time to time.

(o) However, notwithstanding the foregoing, the exercise price of the Underwriter Options, or number of CDIs to be delivered in respect of each Underwriter Option or the amount payable, shall not be reduced or otherwise adjusted in connection with the Entitlement Offer currently intended to be undertaken by the Company.

(p) Except as required by the Listing Rules, if the Company makes a pro rata issue of securities, bonus issue of securities or other new issue of securities, the Company must notify the holder in writing on the earlier of 20 Business Days prior to the closing date, and 5 Business Days prior to the record date, of any such issue to enable the holder to exercise the Underwriter Options prior to that date, and participate in the issue if the holder elects to do so.

(q) The holder may only participate in new issues of CDIs (and underlying shares in the Company) by reason of Underwriter Option if the holder exercises that Underwriter Option and becomes the holder of CDIs (or underlying shares) on or prior to the record date for the new issue of CDIs (or underlying shares).

(r) Other than as provided for above, the Underwriter Options do not confer any right upon the optionholder to a change in the exercise price of each Underwriter Option or a change in the number of CDIs over which each Underwriter Option can be exercised.
