In the event of any exercise of the rights represented by this Warrant, book-entry shares of stock (or certificated shares, if so requested by the Holder) so purchased shall be issued in the name of, and registered to, the account of Holder hereof, or as such Holder may direct (subject to the terms of transfer contained herein and upon payment by such Holder hereof of any applicable transfer taxes), on the records of the Company’s transfer agent for its Common Stock. Such registration shall be made within thirty (30) days after exercise of this Warrant and at Company’s expense and, unless this Warrant has been fully exercised or expired, a new Warrant having terms and conditions substantially identical to this Warrant and representing the portion of the Warrant Shares, if any, with respect to which this Warrant shall not have been exercised, shall also be issued to Holder hereof within ten (10) days after exercise of this Warrant. For purposes of this Agreement, “Business Day” means any day other than a Saturday, Sunday or a day on which commercial banking institutions in New York, New York are required by law to be closed.

X = Y (A-B)/A

Where:

X = the number of Warrant Shares to be issued to Holder;

Y = the number of Warrant Shares purchasable under this Warrant or, if only a portion of this Warrant is being exercised, the portion of this Warrant being canceled (at the date of such calculation);

A = the Fair Market Value of one share of Company’s Common Stock (at the date of such calculation); and

B = Warrant Price (as adjusted to the date of such calculation).

(c) Fair Market Value. For purposes of this Section 3, Fair Market Value of one share of Company’s Common Stock shall mean:

(i) The closing price of such of a share of Common Stock on the NASDAQ Global Market or other U.S. trading market where the Common Stock is listed or traded as published in the Western Edition of the Wall Street Journal; or, if none of the foregoing are applicable, the ASX Price. “ASX Price” shall mean twenty (20) multiplied by Y and again multiplied by FX, where:

(ii) In the event of an exercise in connection with a merger, acquisition or other consolidation in which Company is not the surviving entity, in lie of any determination under 3(c)(i) above, the per share Fair Market Value for the Common Stock shall be the value to be received per share of Common Stock by all holders of the Common Stock in such transaction as determined by the Company’s board of directors of the Company; or

(iii) In the event the Fair Market Value of the Common Stock cannot be determined under 3(c)(i) or 3(c)(ii) above, the per share Fair Market Value for the Common Stock shall be as determined in the reasonable good faith judgment of Company’s board of directors.

In the event of 3(c)(ii) or 3(c)(iii), above, the Company shall prepare a certificate, to be signed by an authorized officer of Company, setting forth in reasonable detail the basis for and method of determination of the per share Fair Market Value of the Common Stock. The officer will also certify to Holder that this per share Fair Market Value will be applicable to all holders of Company’s Common Stock. Such certification must be made to Holder at least ten (10) Business Days prior to the proposed effective date of the merger, consolidation, sale, or other triggering event as defined in 3(c)(ii) or 3(c)(iii).

Notwithstanding anything herein to the contrary, the Company shall not be required to make any cash payments to Holder in lieu of issuance of the Warrant Shares.

(d) Automatic Exercise. To the extent this Warrant is not previously exercised, it shall be deemed to have been automatically converted in accordance with Sections 3(b) and 3(c) hereof (even if not surrendered) immediately before its expiration, involuntary termination or cancellation if the then-applicable Fair Market Value of a Warrant Share exceeds the Warrant Price, unless Holder notifies Company in writing to the contrary prior to such automatic exercise.

(e) Treatment of Warrant Upon Acquisition of Company.

(i) Certain Definitions. For the purpose of this Warrant, “Acquisition” means any sale, license, or other disposition of all or substantially all of the assets of Company, or any reorganization, consolidation, or merger of Company, or sale of outstanding Company securities by holders thereof, where the holders of Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the successor or surviving entity after the transaction. For purposes of this Section 3(e), “Affiliate” shall mean any person or entity that owns or controls, directly or indirectly, 10% percent or more of the stock of Company, any person or entity that controls or is controlled by or is under common control with such persons or entities, and each of such person’s or entity’s officers, directors, joint venturers or partners, as applicable.

(ii) Cash Acquisition. In the event of an Acquisition in which the sole consideration is cash, Holder may either (a) exercise its conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) permit the Warrant to expire upon the consummation of such Acquisition. Company shall provide Holder with written notice of any proposed Acquisition together with such reasonable information as Holder may request in connection with such contemplated Acquisition giving rise to such notice, which is to be delivered to Holder not less than ten (10) Business Days prior to the closing of the proposed Acquisition. Any such exercise may be made prior to, but conditioned on, such Acquisition.

(iii) Asset Sale. In the event of an Acquisition (other than an Acquisition described in 3(e)(ii) above) by a third party that is not an Affiliate of Company (a “True Asset Sale”), Holder may either (a) exercise its conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) permit the Warrant to continue until the Expiration Date if Company continues as a going concern following the closing of any such True Asset Sale. Company shall provide Holder with written notice of any proposed asset sale together with such reasonable information as Holder may request in connection with such asset sale giving rise to such notice, which is to be delivered to Holder not less than ten (10) Business Days prior to the closing of the proposed asset sale. Any such exercise may be made prior to, but conditioned on, such asset sale.

(iv) Assumption of Warrant. Upon the closing of any Acquisition other than those particularly described in subsections (ii) and (iii) above, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as would be payable for the Warrant Shares issuable upon exercise of the unexercised portion of this Warrant as if such Warrant Shares were outstanding on the record date for the Acquisition and subsequent closing. The Warrant Price and/or number of Warrant Shares shall be adjusted accordingly so that Holder is neither advantaged or disadvantaged as a consequence of the Acquisition.

4. Representations and Warranties of Holder. Holder represents and warrants to Company with respect to this purchase as follows:

(a) Evaluation. Holder has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the private placement transactions of securities of companies similar to the Company, has so evaluated the merits and risks of such investment and has the capacity to protect its interests.

(b) Resale. Holder is acquiring this Warrant and the Warrant Shares issuable upon exercise of this Warrant (collectively the “Securities”) for investment for its own account and not with a view to, or for resale in connection with, any distribution thereof. Holder agrees that it will neither offer nor sell any Securities during the Distribution Compliance Period (as defined in Rules 902(f) and 903(b)(3)(iii) of Regulation S of the Securities Act of 1933, as amended (the “Securities Act”)) to “U.S. Persons” (as defined in Rule 902(k) of Regulation S). The Holder will, after the expiration of the Distribution Compliance Period, offer, sell, pledge or otherwise transfer any of the Securities only (1) in accordance with Regulation S, (2) following the effective date of a registration statement registering the resale of the Securities or (3) pursuant to an available exemption from registration under the Securities Act, the availability of which is to be established by an opinion of Holder’s counsel to the Company, or other evidence satisfactory to the Company that such exemption is available. Holder understands that the Securities have not been registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent as expressed herein. It being understood that Holder is permitted to transfer the Securities to an Affiliate in compliance with the provisions of the Securities Act and applicable state securities or “blue sky” laws.

(c) Australian resale. Holder acknowledges that an offer of the Securities for sale within twelve (12) months after their issue may require disclosure to investors under Part 6D.2 of the Corporations Xxx 0000 (Cth) (the “Corporations Act”). The Holder further acknowledges that if any of these Securities are subsequently sold, or offered for sale, within twelve (12) months after issue, there

is a risk that these Securities will be taken to be issued or acquired with the purposes referred to in section 707(3) of the Corporations Act.

(c) Holder Status. Holder (i) is not a “U.S. Person” and has not, and will not, acquire the Securities for the account of any “U.S. Person”, (ii) no director or executive officer of Holder is a national or citizen of the United States and (iii) Holder is not otherwise deemed to be a “U.S. Person.” Holder is either a “Sophisticated Investor” within the meaning of section 708(8) or a “Professional Investor” within the meaning of section 708(11) of the Corporations Act.

(d) Opportunity To Discuss. Holder has had an opportunity to discuss Company’s business, management and financial affairs with its management and an opportunity to review Company’s facilities. Holder understands that such discussions, as well as the written information issued by Company, were intended to describe the aspects of Company’s business and prospects which Company believes to be material but were not necessarily a thorough or exhaustive description.

(e) CHESS Depositary Interests. Upon exercise of the Warrant, in whole or in part, and receipt by Holder of Warrant Shares, Holder will not convert any Warrant Shares into the Company’s CHESS Depositary Interests prior to the earlier of (i) such Warrant Shares being registered under the Securities Act (nothing contained in this paragraph shall be deemed to require the Company to so register the Warrant Shares) or (ii) such Warrant Shares being freely tradeable by Holder pursuant to Rule 144 promulgated under the Securities Act or otherwise pursuant to the Securities Act.

(f) Hedging Transactions. Holder agrees that it will not engage in any hedging transition with respect to the Securities, except in compliance with the Securities Act.

5. Legends.

(a) Legend. Book-entry shares representing the Warrant Shares shall bear the following legend:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN OFFERED AND SOLD IN AN “OFFSHORE TRANSACTION” IN RELIANCE UPON REGULATION S AS PROMULGATED BY THE SECURITIES AND EXCHANGE COMMISSION. ACCORDINGLY, THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE UNITED STATES, OR TO, OR FOR, THE ACCOUNT OF, OR BENEFIT OF, A U.S. PERSON, OTHER THAN DISTRIBUTORS (AS DEFINED IN

REGULATION S) OTHER THAN IN (1) ACCORDANCE WITH REGULATION S, (2) PURSUANT TO REGISTRATION UNDER THE SECURITIES ACT, OR (3) PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, THE AVAILABILITY OF WHICH IS TO BE ESTABLISHED BY AN OPINION OF HOLDER’S COUNSEL TO THE COMPANY, OR OTHER EVIDENCE SATISFACTORY TO THE COMPANY THAT SUCH EXEMPTION IF AVAILABLE.”

The Company need not enter into its stock records a transfer of Warrant Shares unless the conditions specified in the foregoing legend are satisfied. The Company may also instruct its transfer agent not to allow the transfer of any of the Warrant Shares unless the conditions specified in the foregoing legend are satisfied.

(b) Removal of Legend and Transfer Restrictions. The legend relating to the Securities Act described in paragraph 5(a) of this Warrant shall be removed and Company shall cause the issuance of book-entry shares without such legend to Holder if (i) the Securities are registered under the Securities Act and a prospectus meeting the requirements of Section 10 of the Securities Act is available, nothing herein contained shall be deemed to require the Company to so register this Warrant or the Warrant Shares pursuant to an effective Registration Statement filed under the Securities Act or (ii) a Holder of Securities provides the Company and its transfer agent with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such shares may be made without registration under the Securities Act and such sale either has occurred or may occur without restriction on the manner of such sale or transfer.

6. Condition of Transfer or Exercise of Warrant. It shall be a condition to any transfer or exercise of this Warrant that at the time of such transfer or exercise, Holder shall provide Company with a representation in writing that Holder or transferee is acquiring this Warrant and the shares of Common Stock to be issued upon exercise for investment purposes only and not with a view to any sale or distribution, or will provide Company with a statement of pertinent facts covering any proposed distribution. As a further condition to any transfer of this Warrant or any or all of the shares of Common Stock issuable upon exercise of this Warrant, other than a transfer registered under the Securities Act, Company may request a legal opinion, in form and substance satisfactory to Company and its counsel, reciting the pertinent circumstances surrounding the proposed transfer and stating that such transfer is exempt from the registration and prospectus delivery requirements of the Securities Act. The Company shall not require Holder to provide an opinion of counsel if the transfer is to an affiliate of Holder. Each book-entry share evidencing the Warrant Shares issued upon exercise of this Warrant or upon any transfer of the Warrant Shares (other than a transfer registered under the Securities Act or any subsequent transfer of shares so registered) shall, at Company’s option, if the Warrant Shares are not freely saleable under Rule 144 under the Securities Act, contain a legend in form and substance satisfactory to Company and its counsel, restricting the transfer of the Warrant Shares to sales or other dispositions exempt from the requirements of the Securities Act. As further condition to each transfer, at the request of Company, Holder shall surrender this Warrant to

Company and the transferee shall receive and accept a Warrant, of like tenor and date, executed by Company.

7. Adjustment for Certain Events. Subject to the ASX Listing Rules, the number and kind of securities purchasable upon the exercise of this Warrant and the Warrant Price shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a) Reclassification or Merger. In case of (i) any reclassification or change of securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any merger of Company with or into another corporation (other than a merger with another corporation in which Company is the acquiring and the surviving corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant), or (iii) any sale of all or substantially all of the assets of Company, Company, or such successor or purchasing corporation, as the case may be, shall duly execute and deliver to Holder a new Warrant (in form and substance satisfactory to Holder of this Warrant), or Company shall make appropriate provision without the issuance of a new Warrant, so that Holder shall have the right to receive, at a total purchase price not to exceed that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the Warrant Shares theretofore issuable upon exercise or conversion of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification, change, merger or sale by a holder of the number of shares of Common Stock then purchasable under this Warrant, or in the case of such a merger or sale in which the consideration paid consists all or in part of assets other than securities of the successor or purchasing corporation, at the option of Holder, the securities of the successor or purchasing corporation having a value at the time of the transaction equivalent to the value of the Warrant Shares purchasable upon exercise of this Warrant at the time of the transaction. Any new Warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 7. The provisions of this subparagraph (a) shall similarly apply to successive reclassifications, changes, mergers and transfers.

(b) Subdivision or Combination of Shares. If Company at any time while this Warrant remains outstanding and unexpired shall subdivide or combine its outstanding shares of Common Stock, the Warrant Price shall be proportionately decreased and the number of Warrant Shares issuable hereunder shall be proportionately increased in the case of a subdivision, and the Warrant Price shall be proportionately increased and the number of Warrant Shares issuable hereunder shall be proportionately decreased in the case of a combination.

(c) Stock Dividends and Other Distributions. If Company at any time while this Warrant is outstanding and unexpired shall (i) pay a dividend with respect to Common Stock payable in Common Stock, then the Warrant Price shall be adjusted, from and after the date of determination of stockholders entitled to receive such dividend or distribution, to that price determined by multiplying the Warrant Price in effect immediately prior to

such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution; or (ii) make any other distribution with respect to Common Stock (except any distribution specifically provided for in Sections 7(a) and 7(b)), then, in each such case, provision shall be made by Company such that Holder shall receive upon exercise of this Warrant a proportionate share of any such dividend or distribution as though it were Holder of the Warrant Shares as of the record date fixed for the determination of the shareholders of Company entitled to receive such dividend or distribution.

(d) Adjustment of Number of Shares. Upon each adjustment in the Warrant Price, the number of Warrant Shares purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Warrant Shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the denominator of which shall be the Warrant Price immediately thereafter.

(e) ASX Listing Rules. Notwithstanding any other term of this Warrant, the rights of the Holder will be changed to the extent necessary to comply with the ASX Listing Rules applying to a reorganization of capital at the time of the reorganization.

8. Notice of Adjustments. Whenever any Warrant Price or the kind or number of securities issuable under this Warrant shall be adjusted pursuant to Section 7 hereof, Company shall prepare a certificate signed by an officer of Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Warrant Price and number or kind of shares issuable upon exercise of this Warrant after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by certified or registered mail, return receipt required, postage prepaid) within thirty (30) days of such adjustment to Holder as set forth in Section 17 hereof.

Upon any partial transfer, Company will issue and deliver to Holder a new Warrant with respect to the Warrant not so transferred.

10. No Fractional Shares. No fractional share of Common Stock will be issued in connection with any exercise or conversion hereunder, and the number of Warrant Shares to be issued upon conversion shall be rounded up to the nearest whole share.

11. Charges, Taxes and Expenses. Issuance of shares of Common Stock upon the exercise or conversion of this Warrant shall be made without charge to Holder for any United States or state of the United States documentary stamp tax or other incidental expense with respect to the

issuance of such shares, all of which taxes and expenses shall be paid by Company, and such shares shall be issued in the name of Holder.
