The Company hereby agrees to use commercially reasonable efforts to maintain the listing of the Ordinary Shares and ADSs on the ASX and NYSE MKT, respectively, and the Company shall file the applications to list all of ADSs and the ADSs for which the Warrant Shares may be exchanged on the NYSE MKT, no later than the date of their issuance. The Company further agrees that, if the Company applies to have the Ordinary Shares or ADSs traded on any other stock exchange, it will include in such application all of the Warrant Shares and related ADSs will take such other action as is necessary to cause all of the Warrant Shares and related ADSs to be listed on such other stock exchange as promptly as possible.

4.9 Certain Transactions and Confidentiality After the Date Hereof . Notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions in the Securities or any other securities of the Company after the time that the transactions contemplated by this Agreement are publicly announced by the Press Release and the Form 8-K.

4.10 Future Sales of Securities . Purchasers will have no right of first refusal, right of participation or other rights with respect to any future offers or sales of Ordinary Shares, ADSs or other securities by the Company, provided, however , the parties acknowledge the Company’s intent to commence a rights offering immediately following the Closing by which holders of Ordinary Shares and ADSs will be offered the right to purchase a number of the same securities as are sold in the Offering, at the same price and on substantially identical terms as the Offering, in proportion to the Ordinary Shares held at the time of that rights issue. Purchasers further acknowledge that, following the Offering, the Company may offer or sell other securities, including but not limited to the issuance or grant of (a) Ordinary Shares or ADSs upon the exercise of currently outstanding warrants or options, (b) options or other securities under the Company’s current or future incentive compensation plans, (c) bonds, debentures, long term promissory notes or other debt securities and (d) options, warrants or other equity derivative securities to lenders providing debt financing to the Company.

4.11 Warrants and Warrant Exercise Procedures . The terms and conditions of the Warrants are set forth in Exhibit B , and are supplemented as follows:

(a) The Warrants are transferable and an application shall be made to list the Warrants on the ASX.

(b) Warrants may be exercised in whole or in part. Upon partial exercise of a Warrant, the records of the Company’s registry for Ordinary Shares, Security Transfer Registrars, will be changed to reflect the exercise and evidence of the exercise will be available to the Purchaser upon request. No fractional share of an Ordinary Share will be issued upon any exercise of a Warrant and no fractional share of an ADS will be issued upon exchange of Warrant Shares for ADSs.

(c) A Warrant may be exercised by (i) written notice to the Company in accordance with Section 5.3 hereof and (ii) tender of the Warrant Exercise Price, in United States dollars or Australian dollars, to the Company. United States dollars tendered will be converted to Australian dollars as provided in Section 2.2 hereof.

(d) Unless the context otherwise requires, the issuance and sale of the Warrant Shares, and the exchange of Warrant Shares for ADSs, shall be effected in the same manner as the issuance of the Ordinary Shares and exchange of ADSs in the Offering set forth in Article II of this Agreement except that the Closing Date may be set by the Warrant holder in the notice of exercise so long as such Closing Date is no sooner than one (1) full business day after the date of notice of exercise as determined by Section 5.3 of this Agreement.

(e) If the Company establishes a record date for holders of Ordinary Shares or ADSs for the purpose of:

(i) entitling them to receive any dividend other than a cash dividend or other distribution, or any right to subscribe for or purchase additional shares or other securities of the Company, or to receive any other right (a “ Non-Cash Dividend ”);

(ii) any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Company’s assets to another person or entity or other similar transaction (an “ Organic Change”) ; or

(iii) any voluntary dissolution, liquidation or winding-up of the Company (a “ Dissolution ”);

then, the Company will mail or cause to be mailed to each registered holder of outstanding Warrants at the time outstanding a notice specifying, as the case may be, (i) the date on which a record is to be taken for the purpose of such Non-Cash Dividend, and stating the amount and character of such Non-Cash Dividend or (ii) the date on which any Organic Change or Dissolution, is to take place, and the time, if any, is to be fixed, as of which the holders of record of Ordinary Shares or ADSs shall be entitled to exchange their shares for securities or other property deliverable upon such Organic Change or Dissolution. Such notice shall be mailed at least fifteen (15) days prior to the record date therein specified, or if no record date shall have been specified therein, at least fifteen (15) days prior to such specified date, provided, however, failure to provide any such notice shall not under any circumstances affect the validity of such transaction.

(f) In connection with any (x) bona fide sale of all or substantially all of the Company’s assets to an acquiring person or entity or (y) other Organic Change involving an arm’s length third party or parties following which the Company is not the surviving entity and as a result of which the then current shareholders of the Company will not, directly or indirectly own 50% or more of the surviving entity, the Company shall elect in its sole discretion: (A) to require that the holders of outstanding Warrants exercise the outstanding Warrants prior to the consummation of such Organic Change, and if not so exercised, that the outstanding Warrants shall terminate upon consummation of such Organic Change, or (B) to secure from the person or entity purchasing such assets or the successor resulting from such Organic Change (in each case, the “ Acquiring Entity ”) a written agreement to issue to the holders of the outstanding Warrants, in exchange for the surrender of the Warrants, warrants of the Acquiring Entity (the “ Replacement Warrants ”) evidenced by a written instrument substantially similar in form and substance to the outstanding Warrants reflecting the adjustments required so as to preserve the value of the Warrants applicable at the closing of the transaction, by the terms of the Replacement Warrants. The Company shall give the holders of the outstanding Warrants written notice of such Organic Change at least twenty (20) days prior to the closing and consummation of such Organic Change and shall give notice of the record date pursuant to Section 4.11(e) hereof.

(g) If and to the extent permitted by the ASX Listing Rules, the outstanding Warrants will be subject to the following capital adjustments:

(i) Subdivision or Combination of Shares . If the Company at any time while any of the Warrants remain outstanding and unexpired shall subdivide or combine its Ordinary Shares, the number of Warrant Shares purchasable upon exercise of the outstanding Warrants and the Warrant Exercise Price of the outstanding Warrants shall be proportionately adjusted. Any adjustment under this Section 4.11(g)(i) shall become effective at the close of business on the date the subdivision or combination becomes effective or, if earlier, the record date with respect to the subdivision or combination.

(ii) Stock Dividends and Distributions . If the Company at any time while any of the Warrants are outstanding and unexpired shall issue or pay the holders of its Ordinary Shares, or take a record of the holders of its Ordinary Shares for the purpose of entitling them to receive, a dividend payable in, or other distribution of, Ordinary Shares, then (A) the Warrant Exercise Price of the outstanding Warrants shall be adjusted in accordance with Section 4.11(g)(i) and (B) the number of Warrant Shares purchasable upon exercise of the outstanding Warrants shall be adjusted to the number of Ordinary Shares as if the outstanding Warrants been exercised immediately prior thereto.

(iii) Whenever the number of Warrant Shares purchasable upon exercise of the outstanding Warrants is adjusted, as herein provided, the Warrant Exercise Price payable upon the exercise of the outstanding Warrants shall be adjusted to that price determined by multiplying the Warrant Exercise Price immediately prior to such adjustment by a fraction (A) the numerator of which shall be the number of Warrant Shares purchasable upon exercise of the outstanding Warrants immediately prior to such adjustment, and (B) the denominator of which shall be the number of Warrant Shares purchasable upon exercise of the outstanding Warrants immediately thereafter.

(h) Under no circumstances will any of the rights of holders of outstanding Warrants or adjustments to outstanding Warrants set forth in subsections (e), (f) and (g) be given retroactive effect for the benefit of holders of Warrants that have previously been exercised or expired or otherwise terminated.

(i) In the event of any conflict or inconsistency between the provisions of this Article 4.11 and the provisions of the ASX Listing Rules, the latter shall prevail to the extent of that conflict or inconsistency.

(j) To the extent possible, the terms of the Warrants will be the same as the terms of the warrants to be issued in connection with the rights offering referred to in Section 4.10.
