Ladies and Gentlemen:

Introduction. Subject to the terms and conditions herein (this “Agreement”), Benitec Biopharma Limited, of Level 14, 114 William Street, Melbourne 3000, Victoria, Australia, an Australian public company incorporated under the laws of the Commonwealth of Australia (the “Company”), hereby agrees to sell up to an aggregate of $2,249,004.10 of securities of the Company, including, but not limited to, registered American Depositary Shares (the “Shares”), unregistered warrants to purchase Shares (the “Unregistered Warrants”), registered warrants to purchase Shares (the “Registered Warrants” and collectively with the Unregistered Warrants, the “Warrants”) and the Shares issuable upon exercise of the Warrants, the “Warrant Shares”) (the Shares, the Warrants, and the Warrant Shares, collectively, the “Securities”) directly to various investors (each, an “Investor” and, collectively, the “Investors”) through Ladenburg Thalmann & Co. Inc. (the “Placement Agent”) as placement agent. The documents executed and delivered by the Company and the Investors in connection with the Offering (as defined below), including, without limitation, a securities purchase agreement (the “Purchase Agreement”), shall be collectively referred to herein as the “Transaction Documents.” The Placement Agent may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Offering (as defined below).

The Company hereby confirms its agreement with the Placement Agent as follows:

Section 1. Agreement to Act as Placement Agent.

(a) On the basis of the representations, warranties and agreements of the Company herein contained, and subject to all the terms and conditions of this Agreement, the Placement Agent shall be the exclusive placement agent in connection with the offering and sale by the Company of the Shares and Registered Warrants pursuant to the Company’s registration statement on Form F-3 (File No. 333-218400) (the “Registration Statement”) (such offering, the “Registered Offering”) and a concurrent private placement of the Unregistered Warrants (such private placement, the “Private Placement” and, together with the Registered Offering, the “Offering”) with the terms of the Offering to be subject to market conditions and negotiations between the Company, the Placement Agent and the prospective Investors. The Placement Agent will act on a reasonable best efforts basis and the Company agrees and acknowledges that there is no guarantee of the successful placement of the Securities, or any portion thereof, in the prospective Offering. Under no circumstances will the Placement Agent or any of its “Affiliates” (as defined below) be obligated to underwrite or purchase any of the Securities for its own account or otherwise provide any financing. The Placement Agent shall act solely as the Company’s agent and not as principal. The Placement Agent shall have no authority to bind the Company with respect to any prospective offer to purchase Securities and the Company shall have the sole right to accept offers to purchase Securities and may reject any such offer, in whole or in part. Subject to the terms and conditions hereof, payment of the purchase price for, and delivery of, the Securities shall be made at one or more closings (each a “Closing” and the date on which each Closing occurs, a “Closing Date”). As compensation for services rendered, on each Closing Date, the Company shall pay to the Placement Agent the fees and expenses set forth below:

A cash fee equal to 8% of the gross proceeds received by the Company from the sale of the Securities at the closing of the Offering (the “Closing”).

The Company also agrees to reimburse Placement Agent’s expenses (with supporting invoices/receipts) in the amount of up to $165,000; provided, however, that such reimbursement cap in no way limits or impairs the indemnification and contribution provisions of this Agreement. Such reimbursement shall be payable immediately upon a Closing of the Offering.

(b) The term of the Placement Agent’s exclusive engagement will be as provided in Section 2 of that certain Investment Banking Agreement dated August 21, 2019 between the Company and the Placement Agent (the “Investment Banking Agreement”). Notwithstanding anything to the contrary contained herein, the provisions concerning confidentiality, indemnification and contribution contained herein and the Company’s obligations contained in the indemnification provisions will survive any expiration or termination of this Agreement, and the Company’s obligation to pay fees actually earned and payable and to reimburse expenses actually incurred and reimbursable pursuant to Section 1 hereof and which are permitted to be reimbursed under FINRA Rule 5110(f)(2)(D)(i), will survive any expiration or termination of this Agreement. Nothing in this Agreement shall be construed to limit the ability of the Placement Agent or its Affiliates to pursue, investigate, analyze, invest in, or engage in investment banking, financial advisory or any other business relationship with Persons (as defined below) other than the Company. As used herein (i) “Person” means an individual or corporation, partnership, trust, incorporated or unincorporated association, joint venture, limited liability company, joint stock company, government (or an agency or subdivision thereof) or other entity of any kind and (ii) “Affiliate” means any Person that, directly or indirectly through one or more intermediaries, controls or is controlled by or is under common control with a Person as such terms are used in and construed under Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”).

Section 2. Representations, Warranties and Covenants of the Company. The Company hereby represents, warrants and covenants to the Placement Agent as of the date hereof, and as of each Closing Date, as follows:

(a) Securities Law Filings. The Company has filed with the Securities and Exchange Commission (the “Commission”) the Registration Statement under the Securities Act, which was declared effective on July 5, 2017 for the registration of certain securities of the Company, including the Shares being sold hereby, but not including the Unregistered Warrants or the Warrant Shares issuable upon exercise of the Unregistered Warrants. At the time of such filing, the Company met the requirements of Form F-3 under the Securities Act, subject to the transaction requirements with respect to the aggregate market value of securities being sold pursuant to this offering and during the twelve (12) months prior to this offering, as set forth in General Instruction I.B.5 of Form F-3. Following the determination of pricing among the Company and the prospective Investors introduced to the Company by the Placement Agent, the Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules and regulations (the “Rules and Regulations”) of the Commission promulgated thereunder, a prospectus supplement relating to the terms of the Registered Offering and the Shares and the plan of distribution thereof and will advise the Placement Agent of all further information (financial and other) with respect to the Company required to be set forth therein. Such

2

Registration Statement, at any given time, including any information contained in a Prospectus Supplement (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act or deemed to be a part of such registration statement pursuant to Rule 430B under the Securities Act and including the exhibits thereto filed at such time, as amended at such time, is hereinafter included in the term “Registration Statement”; such base prospectus in the form in which it appears in the Registration Statement is hereinafter called the “Base Prospectus”; and the amended or supplemented form of prospectus, in the form in which it will be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so amended or supplemented) is hereinafter called the “Prospectus Supplement.” The Registration Statement at the time it originally became effective is hereinafter called the “Original Registration Statement.” Any reference in this Agreement to the Registration Statement, the Original Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”), if any, which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), at any given time, as the case may be; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Original Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information that is “contained,” “included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be. The Company has not received any notice that the Commission has issued or intends to issue a stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus Supplement or intends to commence a proceeding for any such purpose.

(b) Assurances. The Original Registration Statement, as amended, (and any further documents to be filed with the Commission) when declared effective and as of the date of the most recent amendment thereto, contained all exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations and did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Base Prospectus, and the Prospectus Supplement, each as of its respective date, comply or will comply in all material respects with the Securities Act and the applicable Rules and Regulations. Each of the Base Prospectus and the Prospectus Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Incorporated Documents, when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein (with respect to Incorporated Documents incorporated by reference in the Base Prospectus and Prospectus Supplement), in light of the circumstances under which they were made not misleading. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually or in the aggregate, a

fundamental change in the information set forth therein is required to be filed with the Commission. There are no documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have not been filed as required pursuant to the Securities Act or (y) will not be filed within the requisite time period.

Section 4. Covenants and Agreements of the Company. The Company further covenants and agrees with the Placement Agent as follows:

(a) Registration Statement Matters. The Company will advise the Placement Agent promptly after the Company receives notice thereof of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Base Prospectus or the Prospectus Supplement has been filed and will furnish the Placement Agent with copies thereof. The Company will file promptly all reports and any definitive proxy or

5

information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 14 or 15(d) of the Exchange Act subsequent to the date of any Prospectus Supplement and for so long as the delivery of a prospectus is required in connection with the Registered Offering. The Company will advise the Placement Agent, promptly after it receives notice thereof (i) of any request by the Commission to amend the Registration Statement or to amend or supplement any Prospectus Supplement or for additional information, and (ii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any order directed at any Incorporated Document, if any, or any amendment or supplement thereto or any order preventing or suspending the use of the Base Prospectus or the Prospectus Supplement or any prospectus supplement or any amendment or supplement thereto or any post-effective amendment to the Registration Statement, of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, of the institution or threatened institution of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement or a Prospectus Supplement or for additional information. The Company shall use its best efforts to prevent the issuance of any such stop order or prevention or suspension of such use. If the Commission shall enter any such stop order or order or notice of prevention or suspension at any time prior to the completion of the Registered Offering, the Company will use its best efforts to obtain the lifting of such order at the earliest possible moment, or will file a new registration statement and use its best efforts to have such new registration statement declared effective as soon as practicable. Additionally, the Company agrees that, in connection with the Registered Offering, it shall comply with the provisions of Rules 424(b), 430A, 430B and 430C, as applicable, under the Securities Act, including with respect to the timely filing of documents thereunder, and will use its commercially reasonable efforts to confirm that any filings made by the Company under such Rule 424(b) are received in a timely manner by the Commission.

(b) Blue Sky Compliance. The Company will use commercially reasonable efforts to cooperate with the Placement Agent and the Investors in endeavoring to qualify the Securities for sale under the securities laws of such jurisdictions (United States and foreign) as the Placement Agent and the Investors may reasonably request and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided that the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent, and provided further that the Company shall not be required to produce any new disclosure document. The Company will, from time to time, prepare and file such statements, reports and other documents as are or may be required to continue such qualifications in effect for so long a period as the Placement Agent may reasonably request for distribution of the Securities. The Company will advise the Placement Agent promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its commercially reasonable efforts to obtain the withdrawal thereof at the earliest possible moment.

(c) Amendments and Supplements to a Prospectus and Other Matters. The Company will comply with the Securities Act and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement, the Incorporated Documents and the Prospectus Supplement. If during the period in which a prospectus is required by law to be delivered in connection with the distribution of Shares contemplated by the Incorporated Documents or any Prospectus Supplement (the “Prospectus Delivery Period”), any event shall occur as a result of which, in the

6

judgment of the Company or in the reasonable opinion of the Placement Agent or counsel for the Placement Agent, it becomes necessary to amend or supplement the Incorporated Documents or any Prospectus Supplement in order to make the statements therein, in the light of the circumstances under which they were made, as the case may be, not misleading, or if it is necessary at any time to amend or supplement the Incorporated Documents or any Prospectus Supplement or to file under the Exchange Act any Incorporated Document to comply with any law, the Company will promptly prepare and file with the Commission, and furnish at its own expense to the Placement Agent and to dealers, an appropriate amendment to the Registration Statement or supplement to the Registration Statement, the Incorporated Documents or any Prospectus Supplement that is necessary in order to make the statements in the Incorporated Documents and any Prospectus Supplement as so amended or supplemented, in the light of the circumstances under which they were made, as the case may be, not misleading, or so that the Registration Statement, the Incorporated Documents or any Prospectus Supplement, as so amended or supplemented, will comply with law. Before amending the Registration Statement or supplementing the Incorporated Documents or any Prospectus Supplement in connection with the Registered Offering, the Company will furnish the Placement Agent with a copy of such proposed amendment or supplement and will not file any such amendment or supplement to which the Placement Agent reasonably objects within two (2) Business Days, provided that the Company may file any document or report reasonably determined by the Company to be required to be filed by the Company pursuant to the Securities Act or the Exchange Act or the rules and regulations promulgated thereunder within the time periods required for such filings, irrespective of any such objection of the Placement Agent.

(d) Copies of any Amendments and Supplements to a Prospectus. The Company will furnish the Placement Agent, without charge, during the period beginning on the date hereof and ending on the later of the last Closing Date of the Registered Offering, as many copies of the Incorporated Documents and any Prospectus Supplement and any amendments and supplements thereto (including any Incorporated Documents, if any), as the Placement Agent may reasonably request.

(e) Free Writing Prospectus. The Company covenants that it will not, unless it obtains the prior written consent of the Placement Agent, make any offer relating to the Shares that would constitute an issuer free writing prospectus (as defined in Rule 433 of the Securities Act) (“Company Free Writing Prospectus”) or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act.

(f) Depositary. The Company will maintain, at its expense, a depositary for the Shares until such date as no Warrants are outstanding.

(g) Periodic Reporting Obligations. During the Prospectus Delivery Period, the Company will duly file, on a timely basis, with the Commission and the Trading Market (as defined in the Purchase Agreement) all reports and documents required to be filed under the Exchange Act within the time periods and in the manner required by the Exchange Act.

(h) Additional Documents. The Company will enter into any subscription, purchase or other customary agreements as the Placement Agent or the Investors deem reasonably necessary or appropriate to consummate the Offering, all of which will be in form and substance reasonably acceptable to the Company, the Placement Agent and the Investors. The Company agrees that the Placement Agent may rely upon, and each is a third party beneficiary of, the representations and warranties, and applicable covenants, set forth in any such purchase, subscription or other agreement with Investors in the Offering.

7

(i) No Manipulation of Price. The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(j) Acknowledgment. The Company acknowledges that any advice given by the Placement Agent to the Company is solely for the benefit and use of the Board of Directors of the Company and may not be used, reproduced, disseminated, quoted or referred to, without the Placement Agent’s prior written consent.

(k) Announcement of Offering. The Company acknowledges and agrees that the Placement Agent may, subsequent to the Closing, make public its involvement with the Offering.

(l) Reliance on Others. The Company confirms that it will rely on its own counsel and accountants for legal and accounting advice.

(m) Research Matters. By entering into this Agreement, the Placement Agent does not provide any promise, either explicitly or implicitly, of favorable or continued research coverage of the Company and the Company hereby acknowledges and agrees that the Placement Agent’s selection as a placement agent for the Offering was in no way conditioned, explicitly or implicitly, on the Placement Agent providing favorable or any research coverage of the Company. In accordance with FINRA Rule 2711(e), the parties acknowledge and agree that the Placement Agent has not directly or indirectly offered favorable research, a specific rating or a specific price target, or threatened to change research, a rating or a price target, to the Company or inducement for the receipt of business or compensation.

A “Debt Repayment Triggering Event” means any event or condition that gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of Indebtedness (or any Person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such Indebtedness by any of the Company or a Subsidiary.

(e) Filings, Consents and Approvals.

(f) Issuance of the Securities, Registration.

(i) The Securities to be sold by the Company and their issue and sale and the underlying Shares and their issue are duly authorized and, when issued and paid for in accordance with the applicable Transaction Documents, will be duly and validly issued, fully paid and free and clear of all Liens imposed by the Company. Upon the due issuance by the Depositary of the ADRs evidencing the ADSs against the deposit of the Shares in accordance with the provisions of the Deposit Agreement, such ADRs will be duly and validly issued under the Deposit Agreement and Persons in whose name such ADSs are registered will be entitled to the right of registered holders of ADSs evidencing the ADSs specified therein and in the Deposit Agreement. The Company has the capacity to issue the maximum number of Securities and Shares issuable pursuant to this Agreement. The holder of the Securities will not be subject to personal liability by reason of being such holders. The Securities are not and will not be subject to the preemptive rights of any holders of any security of the Company or similar contractual rights granted by the Company. All corporate action required to be taken for the authorization, issuance and sale of the Securities has been duly and validly taken. Except for limitations expressly set forth in the Transaction Documents, there are no limitations on the rights of holders of the Securities to hold or transfer their securities.

(ii) The Company has prepared and filed the Registration Statement in conformity with the requirements of the Securities Act, which became effective on July 5, 2017 (the “Effective Date”), including the Prospectus, and such amendments and supplements thereto as may have been required to the date of this Agreement. The Registration Statement is effective under the Securities Act and no stop order preventing or suspending the effectiveness of the Registration Statement or suspending or preventing the use of the Prospectus has been issued by the Commission and no proceedings for that purpose have been instituted or, to the knowledge of the Company, are threatened by the Commission. At the time the Registration Statement and any amendments thereto became effective, at the date of this Agreement and at the Closing Date, the Registration Statement and any amendments thereto conformed and will conform in all material respects to the requirements of the Securities Act and did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; and the Prospectus and any amendments or supplements thereto, at the time the Prospectus or any amendment or supplement thereto was issued and at the Closing Date, conformed and will conform in all material respects to the requirements of the Securities Act and did not and will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Company was at the time of the filing of the Registration Statement, and is as of the date hereof, eligible to use Form F-3, subject to the transaction requirements with respect to the aggregate market value of securities being sold pursuant to this offering and during the twelve (12) months prior to this offering, as set forth in General Instruction I.B.5 of Form F-3.

(iv) All amounts payable by the Company in respect of the Securities shall be made free and clear of and without deduction for or on account of any taxes imposed, assessed or levied by Australia or any authority thereof or therein nor are any taxes imposed in Australia on, or by virtue of the execution or delivery of, such documents (other than stamp duty payable if such original documents are brought to, executed in or produced before a court in Australia).

(g) Compliance. The Company is not the subject of a determination or order issued by ASIC nor has ASIC given any notice of intention to hold an investigation in relation to the Company, and the Company is not aware of any such determination, order or investigation being contemplated or threatened by the ASIC. The Company is a disclosing entity under the securities laws of the Commonwealth of Australia, including, without limitation, the Corporations Act (the “Australian Securities Laws”), and is not in default of any requirement of the Australian Securities Laws. All disclosure and filings on the public record and fees required to be made and paid by the Company pursuant to the Australian Securities Laws have been made and paid. None of the Company or any Subsidiary is (i) in breach of or in default under any laws, regulations, rules, orders, decrees, guidelines or notices of Australia, the United States, or any other jurisdiction where it was incorporated or operates, (ii) in breach of or in default under any approval, consent, waiver, authorization, exemption, permission, endorsement or license granted by any Governmental Authority in Australia, the United States or any other jurisdiction in which it was incorporated or operates, (iii) in violation of its constituent documents or (iv) in default in the performance or observance of any obligation, agreement, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound except, with respect to (iv), where any default would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(h) Stamp Tax. No stamp or other issuance or transfer taxes or duties are payable by or on behalf of any Purchaser or any investor to the government of Australia, the United States or any political subdivision or taxing authority thereof or therein in connection with (i) the issuance and delivery by the Company of the Securities or the issuance and delivery of the ADSs upon exercise of the Warrants to or for the account of any investor and (ii) the execution and delivery of the Transaction Documents, in each case other than income tax that is imposed on the investor’s net income in the ordinary course of business.

(i) No Limitations on Dividends and Distributions. Under current laws and regulations of Australia and any political subdivision thereof, all interest, principal, premium, if any, and other payments due or made on the Securities and dividends and other distributions declared and payable on the ADSs or the Ordinary Shares underlying the ADSs may be paid by the Company to the holder thereof in U.S. dollars and freely transferred out of Australia and all such payments made to holders thereof or therein who are non-residents of Australia will other than withholding tax (if applicable) not be

15

subject to income, withholding or other taxes under laws and regulations of Australia or any political subdivision or taxing authority thereof or therein and will otherwise be free and clear of any other tax, duty, withholding or deduction in Australia or any political subdivision or taxing authority thereof or therein and without the necessity of obtaining any governmental authorization in Australia or any political subdivision or taxing authority thereof or therein.

(j) Enforceability in Australia. To ensure the legality, validity, enforceability or admissibility into evidence in Australia of the Transaction Documents, it is not necessary that Transaction Documents be filed or recorded with any court or other authority in Australia or that any stamp or similar tax in Australia be paid on or in respect of this Agreement or any other documents to be furnished hereunder unless they are brought to, executed in or produced before a court in Australia.

(k) Choice of Law in Australia. Under the laws of Australia, the courts of Australia will recognize and give effect to the choice of law provisions set forth in Section 5.9 hereof and would recognize as a valid judgment a final and conclusive judgment in personam obtained in any U.S. court against the Company to enforce this Agreement or the Transaction Documents under which a fixed sum of money is payable (other than a sum of money payable in respect of multiple damages, taxes or other charges of a like nature or in respect of a fine or other penalty) and such judgment would be capable of enforcement by Australian courts provided that (i) such court had proper jurisdiction over the parties subject to such judgment; (ii) the applicable U.S. court did not contravene the rules of natural justice of Australia; (iii) such judgment was not obtained by fraud; (iv) the enforcement of the judgment would not be contrary to the public policy of Australia; (v) such judgment imposes on the judgment debtor a liability to pay a liquidated sum; (vi) such judgment has not been wholly satisfied; (vii) such judgment was obtained within the previous twelve years, and (viii) there is due compliance with the correct procedures under the laws of Australia. Except as described in the Registration Statement and the Prospectus, under the laws of Australia, the choice of law provisions set forth in Section 5.9 hereof will be recognized by the courts of Australia and any judgment obtained in any U.S. state or federal court arising out of or in relation to the obligations of the Company under this Agreement will be recognized in Australian courts and be capable of enforcement subject to the applicable statutory and common law principles of Australia relating to the enforceability of foreign judgments.

(l) Enforced in Australia. Any final judgment for a fixed sum of money rendered by any U.S. state or federal court having jurisdiction under its own domestic laws in respect of any suit, action or Proceeding against the Company based upon this Agreement, would be recognized and enforced against the Company by Australian courts without re-examining the merits of the case, provided that such judgment (i) is not in respect of taxes, a fine or a penalty, (ii) was not obtained by fraud; (iii) was not obtained in a manner and is not a kind the enforcement of which is contrary to natural justice or the public policy of Australia; (iv) such judgment has not been wholly satisfied; and (v) such judgment was obtained within the previous twelve years.

16

(m) Capitalization. The Company has an issued and fully paid up capital as set forth on Schedule 3.1(m), and all of the issued share capital of the Company has been duly and validly authorized and issued, is fully paid and conforms to the description of the Ordinary Shares contained in the Prospectus. All of the issued share capital of each Subsidiary have been duly and validly authorized and issued, and are fully paid in accordance with its Constitution, articles of association or applicable foreign, federal, state and local laws, including, without limitation, the corporate law of the jurisdiction of the Company’s incorporation, and are nonassessable, if applicable. All of the issued share capital or equity interest, as the case may be, of each Subsidiary is owned directly or indirectly by the Company, free and clear of all Liens, equities or claims. Except as set forth on Schedule 3.1(m), the holders of outstanding Ordinary Shares or ADSs are not entitled to preemptive or other rights to acquire the Securities. Except as set forth in Schedule 3.1(m), there are no outstanding securities convertible into or exchangeable for, or warrants, rights or options to purchase from the Company, or obligations of the Company to issue, Ordinary Shares or any other class of share capital of the Company. There are no restrictions on subsequent transfers of the ADSs under the laws of Australia or the United States except as set forth in the Prospectus under the caption “Description of Share Capital,” and “Description of American Depositary Shares”. The issuance and sale of the Securities will not obligate the Company to issue Ordinary Shares or other securities to any Person (other than the Purchasers) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities. No further approval or authorization of any shareholder, the Board of Directors or others is required for the issuance and sale of the Securities. Except as set forth on Schedule 3.1(m), there are no stockholders agreements, voting agreements or other similar agreements with respect to the Company’s capital stock to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s shareholders. Except as set forth on Schedule 3.1(m), there are no outstanding securities convertible into or exchangeable for, or warrants, rights or options to purchase from any Subsidiary, no obligation of any Subsidiary to issue, equity shares or any other class of share capital of any Subsidiary.

The Company has filed or furnished all reports, schedules, forms, statements and other documents required to be filed or furnished by it under the Securities Act and the Exchange Act (including all required exhibits thereto), including pursuant to Section 13(a) or 15(d) of the Exchange Act (the foregoing materials, as the same may be amended, and including the exhibits thereto and documents incorporated by reference therein, being collectively referred to herein as the “SEC Reports”), for the twelve (12) months preceding the date hereof (or such shorter period as the Company was required by law to file such material) and any notices, reports or other filings pursuant to applicable requirements of the Trading Market on a timely basis or has received a valid extension of such time of filing, and has filed any such SEC Reports and notices, reports or other filings pursuant to applicable requirements of the Trading Market prior to the expiration of any such extension. As of their respective dates, the SEC Reports complied in all material respects with the applicable requirements

17

of the Securities Act and the Exchange Act, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing. Such financial statements (i) have been prepared in accordance with IFRS applied on a consistent basis during the periods involved, except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements contain only the footnotes required by IAS 34 “Interim Financial Reporting”, and (ii) fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments. The agreements and documents described in the Registration Statement, the Prospectus, the Prospectus Supplement and the SEC Reports conform to the descriptions thereof contained therein and there are no agreements or other documents required by the Securities Act to be described in the Registration Statement, the Prospectus or the SEC Reports or to be filed with the Commission as exhibits to the Registration Statement, that have not been so described or filed. Each agreement or other instrument (however characterized or described) to which the Company is a party or by which it is or may be bound or affected and (i) that is referred to in the Registration Statement, the Prospectus or the SEC Reports, or (ii) is material to the Company’s business, has been duly authorized and validly executed by the Company, is in full force and effect in all material respects and is enforceable against the Company and, to the Company’s knowledge, the other parties thereto, in accordance with its terms, except (x) as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, (y) as enforceability of any indemnification or contribution provision may be limited under the federal and state securities laws, and (z) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefore may be brought. None of such agreements or instruments has been assigned by the Company, and neither the Company nor, to the best of the Company’s knowledge, any other party is in default thereunder and, to the best of the Company’s knowledge, no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default thereunder. To the best of the Company’s knowledge, performance by the Company of the material provisions of such agreements or instruments will not result in a violation of any existing applicable law, rule, regulation, judgment, order or decree of any Governmental Authority or court, domestic or foreign, having jurisdiction over the Company or any of its assets or businesses, including, without limitation, those relating to environmental laws and regulations. The Company has never been an issuer subject to Rule 144(i) under the Securities Act.

Neither the Company nor any Subsidiary, nor, to the Company’s knowledge, any director or officer thereof, is or has been the subject of any Action involving a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty. There has not been, and to the knowledge of the Company, there is not pending or contemplated, any investigation by the Commission involving the Company or any current or former director or officer of the Company. The Commission has not issued any stop order or other order suspending the effectiveness of any registration statement filed by the Company or any Subsidiary under the Exchange Act or the Securities Act.

None of the Company’s or its Subsidiaries’ employees is a member of a union that relates to such employee’s relationship with the Company or such Subsidiary, and neither the Company nor any of its Subsidiaries is a party to a collective bargaining agreement, and the Company and its Subsidiaries believe that their relationships with their employees are good. To the knowledge of the Company, no executive officer of the Company or any Subsidiary, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information

19

agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of any third party, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(s) Compliance. Neither the Company nor any Subsidiary: (i) is in default under or in violation of (and no event has occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the Company or any Subsidiary under), nor has the Company or any Subsidiary received notice of a claim that it is in default under or that it is in violation of, any indenture, loan or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its properties is bound (whether or not such default or violation has been waived), (ii) is in violation of any judgment, decree or order of any court, arbitrator or other governmental authority or (iii) is or has been in violation of any statute, rule, ordinance or regulation of any governmental authority, including without limitation all foreign, federal, state and local laws relating to taxes, environmental protection, occupational health and safety, product quality and safety and employment and labor matters, except in each case as could not have or reasonably be expected to result in a Material Adverse Effect.

(t) Environmental Laws. The Company and its Subsidiaries (i) are in compliance with all federal, state, local and foreign laws relating to pollution or protection of human health or the environment (including ambient air, surface water, groundwater, land surface or subsurface strata), including laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees, demands, or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations, issued, entered, promulgated or approved thereunder (“Environmental Laws”); (ii) have received all permits licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses; and (iii) are in compliance with all terms and conditions of any such permit, license or approval where in each clause (i), (ii) and (iii), the failure to so comply could be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect.

All of such Material Permits are valid and in full force and effect, except where the invalidity of such Permits or the failure to be in full force and effect, individually or in the aggregate, would not have a Material Adverse Effect on the Company and its subsidiaries, taken as a whole. There is no pending or, to the knowledge of the Company, threatened Proceeding that individually or in the aggregate would reasonably be expected to lead to the revocation, modification, termination, suspension or any other impairment of the rights of the holder of any such Material Permit which revocation, modification, termination, suspension or other impairment would have a Material Adverse Effect on the Company and its subsidiaries, taken as a whole. Such Material Permits contain no material restrictions or conditions not described in the SEC Reports. None of the Company or any Subsidiary has a reasonable basis to believe that any regulatory body is considering modifying, suspending or revoking any such Material Permit and each of the Company and each Subsidiary is in compliance with the provisions of all such Material Permits.

(w) Regulatory Matters. The Company and each of its Subsidiaries: (A) are and at all times have been in material compliance with all statutes, rules and regulations applicable to the ownership, testing, development, manufacture, packaging, processing, use, distribution, marketing, labeling, promotion, sale, offer for sale, storage, import, export or disposal of any product sold, under development, manufactured or distributed by the Company or any subsidiary (“Applicable Regulatory Laws”); (B) have not received any Form 483 from the FDA, notice of adverse finding, warning letter, or other correspondence or written notice from the FDA, the DEA, the ATGA, the EMA, the MHRA or any other federal, state, local, national or foreign governmental or regulatory authority alleging or asserting material noncompliance with any Applicable Regulatory Laws or any licenses, certificates, approvals, clearances, authorizations, permits and supplements or amendments thereto required by any such Applicable Regulatory Laws (“Authorizations”); (C) possess all material Authorizations and such Authorizations are valid and in full force and effect and neither the Company nor any subsidiary is in material violation of any term of any such Authorizations; (D) have not received written notice of any Proceeding, hearing, enforcement, investigation, arbitration or other action from the FDA, the DEA, the ATGA, the EMA, the MHRA or any other federal, state, local, national or foreign governmental or regulatory authority or third party alleging that any product, operation or activity is in material violation of any Applicable Regulatory Laws or Authorizations and has no knowledge that the FDA, the DEA, the ATGA, the EMA, the MHRA or any other federal, state, local, national or foreign governmental or regulatory authority or third party is considering any such Proceeding; (E) have not received written notice that the FDA, DEA, ATGA, EMA, the MHRA or any other federal, state, local, national or foreign governmental or regulatory authority has taken, is taking or intends to take action to limit, suspend, modify or revoke any material Authorizations and has no knowledge that the FDA, DEA, ATGA, EMA, the MHRA or any other federal, state, local, national or foreign governmental or regulatory authority is

21

considering such action; and (F) have filed, obtained, maintained or submitted all reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments as required by any Applicable Regulatory Laws or Authorizations except where the failure to file such reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments would not result in a Material Adverse Effect on the Company and its subsidiaries, taken as a whole, and that all such reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments were materially complete and correct on the date filed (or were corrected or supplemented by a subsequent submission).

(x) Intellectual Property. The Company possesses such right, title and interest in and to, or possesses adequate rights to use, all patents, patent rights, trade secrets, inventions, know-how, trademarks, trade names, copyrights, service marks and other proprietary rights (“Intellectual Property”) material to the conduct of the Company’s business except to Intellectual Property the failure of which to possess would not have a Material Adverse Effect. The Company has not received any notice of infringement or misappropriation from any third party as to Intellectual Property owned by or exclusively licensed to the Company that has not been resolved or disposed of, which infringement or misappropriation would, if the subject of an unfavorable decision, ruling or finding, have a Material Adverse Effect. To the Company’s knowledge, it has not infringed, misappropriated, or otherwise conflicted with the Intellectual Property of any third parties, which infringement, misappropriation or conflict would, if the subject of an unfavorable decision, ruling or finding, have a Material Adverse Effect. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of their intellectual properties, except where failure to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(y) Patents. The pending patent applications set forth in the Registration Statement and the SEC Reports (the “Pending Patents”) are being diligently prosecuted by the Company and/or Subsidiaries. To the Company’s best knowledge, there is no existing patent or published patent application that would interfere, conflict with or otherwise adversely affect the validity, enforcement or scope of the Pending Patents if claims of such Pending Patents were issued in substantially the same form as currently written. Except in each case as set forth in Schedule 3.1(y), no security interests or other Liens have been created with respect to the Pending Patents; and the Pending Patents have not been exclusively licensed to another entity or Person.

(z) Insurance. The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged, including, but not limited to, directors and officers insurance coverage. Neither the Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without a significant increase in cost. There is no material insurance claim made by or against the Company or any Subsidiary pending, threatened or outstanding and no facts or circumstances exist which would reasonably be expected to give rise to any such claim and all due premiums in respective thereof have been paid.

22

The Company and the Subsidiaries have established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and the Subsidiaries and designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms. The Company’s certifying officers have evaluated the effectiveness of the disclosure controls and procedures of the Company and the Subsidiaries as of the end of the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the internal control over financial reporting (as such term is defined in the Exchange Act) of the Company and its Subsidiaries that have materially affected, or is reasonably likely to materially affect, the internal control over financial reporting of the Company and its Subsidiaries.

Except as set forth in Schedule 3.1(gg), the Company has not, in the 12 months preceding the date hereof, received notice from any Trading Market (other than the Company’s deficiency notice received from the Nasdaq Stock Market and described in the Current Report on Form 6-K filed by the Company with the Commission on July 25, 2019) on which the ADSs or Ordinary Shares are or have been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with all such listing and maintenance requirements, except as set forth in Schedule 3.1(gg). The ADSs are currently eligible for electronic transfer through the Depository Trust Company or another established clearing corporation and the Company is current in payment of the fees to the Depository Trust Company (or such other established clearing corporation) in connection with such electronic transfer.

(hh) Application of Takeover Protections. The Company and the Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s constitution (or similar charter documents) or the laws of its jurisdiction that is or could become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

24

(ii) Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company confirms that neither it nor any other Person acting on its behalf has provided any of the Purchasers or their respective agents or counsel with any information that it believes constitutes or might constitute material, non-public information. The Company understands and confirms that the Purchasers will rely on the foregoing representation in effecting transactions in securities of the Company. All of the disclosure furnished by or on behalf of the Company to the Purchasers regarding the Company and its Subsidiaries, their respective businesses and the transactions contemplated hereby, including the Disclosure Schedules to this Agreement is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3.2 hereof.

(jj) No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2, neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of (i) the Securities Act which would require the registration of the ADS Warrants or the Warrant Securities issuable upon exercise of ADS Warrants under the Securities Act, or (ii) any applicable shareholder approval provisions of any Trading Market on which any of the securities of the Company are listed or designated.

(kk) Solvency. Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the Company of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value of the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances which lead it to believe

25

that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date. Schedule 3.1(kk) sets forth, as of the date that is two Business Days prior to the date hereof, all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which the Company or any Subsidiary has commitments.

Neither the Company nor any Subsidiary is in default with respect to any Indebtedness.

The Company has paid or has caused to be paid all material taxes (including any assessments, fines or penalties) required to be paid through the date hereof and all returns, reports or filings which ought to have been made by or in respect of the Company and each Subsidiary for taxation purposes as required by the law of the jurisdictions where the Company and each Subsidiary are incorporated or engage in business have been made and all such returns are correct and on a proper basis in all material respects and are not the subject of any dispute with the relevant revenue or other appropriate authorities except as may be being contested in good faith and by appropriate Proceedings. The provisions included in the audited consolidated financial statements as set out in the Prospectus included appropriate provisions required under IFRS for all taxation in respect of accounting periods ended on or before the accounting reference date to which such audited accounts relate for which the Company was then or might reasonably be expected thereafter to become or have become liable. None of the Company nor any Subsidiary has received notice of any tax deficiency with respect to any of the Company or a Subsidiary. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company or of any Subsidiary know of no basis for any such claim.

The Company further understands and acknowledges that (y) one or more Purchasers may engage in hedging activities at various times during the period that the Securities are outstanding, including, without limitation, during the periods that the value of the Warrant Shares deliverable with respect to Securities are being determined, and (z) such hedging activities (if any) could reduce the value of the existing stockholders’ equity interests in the Company at and after the time that the hedging activities are being conducted. The Company acknowledges that such aforementioned hedging activities do not constitute a breach of any of the Transaction Documents.

(tt) Regulation M Compliance. The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly or indirectly, any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of any of the Securities, (ii) sold, bid for, purchased, or, paid any compensation for soliciting purchases of, any of the Securities, or (iii) paid or agreed to pay to any Person any compensation for soliciting another to purchase any other securities of the Company.

3.2 Representations and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein, in which case they shall be accurate as of such date):

(a) Organization; Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate, partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law. Such Purchaser’s execution, delivery and performance of this Agreement and the other Transaction Documents and the consummation by it of the transactions contemplated hereby do not and will not (i) conflict with or violate any provision of such Purchaser’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which such Purchaser is subject (including foreign, federal and state securities laws and regulations), or by which any property or asset of such Purchaser is bound or affected or (iii) require the consent, notice or other action with respect to any Person, other than an Affiliate, under any contract to which such Purchaser is a party, which consent, notice or action has not been taken.

(b) Understandings or Arrangements. Such Purchaser is acquiring the Securities as principal for its own account and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary course of its business. Such Purchaser understands that the ADS Warrants and the Warrant ADSs issuable upon exercise of the ADS Warrants are “restricted securities” and have not been registered under the Securities Act or any applicable state or foreign securities law and is acquiring such Securities as principal for his, her or its own account and not with a view to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state or foreign securities law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable state or foreign securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities in violation of the Securities Act or any applicable state or foreign securities law (this representation and warranty not limiting such Purchaser’s right to sell such Securities pursuant to a registration statement or otherwise in compliance with applicable federal and state or foreign securities laws).

31

(c) Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on which it exercises any ADS Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a) under the Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act.

(d) Experience of such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser realizes that the purchase of the Securities will be a highly speculative investment and such Purchaser may suffer a complete loss of its investment. Such Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment. Such Purchaser understands that nothing in the Transaction Documents or any other materials presented to such Purchaser in connection with the purchase and sale of the Securities constitutes legal, tax or investment advice. Such Purchaser has reviewed with its own tax advisors the federal, state, and local tax consequences of this investment and the transactions contemplated by this Agreement.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1 Removal of Legends.

(a) The ADS Warrants and the Warrant ADSs issuable upon exercise of the ADS Warrants may only be offered, sold, transferred or otherwise disposed of in full compliance with all state and federal securities laws. In connection with any transfer of the ADS Warrants or the Warrant ADSs issuable upon exercise of the ADS Warrants other than pursuant to an effective registration statement under the Securities Act or Rule 144, to the Company or to an Affiliate of a Purchaser or in connection with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Warrant under the Securities Act.

(b) The Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the ADS Warrants in the following form:

NEITHER THIS SECURITY NOR THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE HAS BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

34

The Company acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the ADS Warrants or the Warrant ADSs issuable upon exercise of the ADS Warrants to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and, if required under the terms of such arrangement, such Purchaser may transfer pledged or secured ADS Warrants or the Warrant ADSs issuable upon exercise of the ADS Warrants to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of ADS Warrants and the Warrant ADSs issuable upon exercise of the ADS Warrants may reasonably request in connection with a pledge or transfer of the ADS Warrants or the Warrant ADSs issuable upon exercise of the ADS Warrants.

(c) The ADS Warrants and the Warrant ADSs issuable upon exercise of the ADS Warrants shall not carry any restriction (including the legend set forth in Section 4.1(b) hereof): (i) while a registration statement covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Warrant ADSs or Warrant Shares pursuant to Rule 144 (assuming cashless exercise of the Warrants and that such Warrant ADSs and Warrant Shares are not then held by an Affiliate of the Company), or (iii) if such Warrant ADSs or Warrant Shares are eligible for sale under Rule 144 (assuming cashless exercise of the ADS Warrants and that such Warrant ADSs and Warrant Shares are not then held by an Affiliate of the Company), or (iv) if such legend is not required under applicable requirements of the Securities Act (including binding judicial interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue a legal opinion to the Registrar or a Purchaser promptly if required by the Registrar to effect the removal of any restriction (including, if applicable, any legend) hereunder, or if requested by such Purchaser, respectively. If all or any portion of an ADS Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or if such Warrant Shares or Warrant ADSs may be sold under Rule 144 (assuming cashless exercise of the ADS Warrants and that such Warrant ADSs and Warrant Shares are not then held by an Affiliate of the Company) or if such legend is not otherwise required under applicable requirements of the Securities Act (including binding judicial interpretations and pronouncements issued by the staff of the Commission) then such Warrant Shares and Warrant ADSs shall be issued unrestricted in electronic form. The Company agrees that following such time as such legend is no longer required under this Section 4.1(c), the Company will, no later than two (2) Trading Days following the delivery by a Purchaser to the Company or the Registrar of Warrant ADSs or Warrant Shares, as applicable, issued with restrictions, including, if applicable, any legend (such date, the “Legend Removal Date”), deliver or cause to be delivered to each Purchaser such Warrant ADSs or Warrant Shares that are unrestricted in electronic form. Except as may be required by applicable law or regulation, the Company may not make any notation on its records or give instructions to the Registrar that enlarge the restrictions on transfer set forth in this Section 4. Warrant ADSs and Warrant Shares subject to restriction removal hereunder shall be transmitted by the Registrar to such Purchaser by crediting the account of such Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser.

35

(d) In addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial liquidated damages and not as a penalty, for each $1,000 of Warrant ADSs underling the ADS Warrants (based on the VWAP on the date that such Securities are submitted to the Registrar) delivered for removal of the restrictive legend and subject to Section 4.1(c), $10 per Trading Day for each Trading Day after the Legend Removal Date until such Warrant ADSs are delivered without a legend and (ii) if the Company fails to (a) issue and deliver (or cause to be delivered) to a Purchaser by the Legend Removal Date such Warrant ADSs so delivered to the Company by such Purchaser that are unrestricted in electronic form and (b) if after the Legend Removal Date such Purchaser purchases (in an open market transaction or otherwise) ADSs in satisfaction of a sale by such Purchaser of all or any portion of the number of ADSs, or a sale of a number of ADSs equal to all or any portion of the number of ADSs, that such Purchaser anticipated receiving from the Company without any restriction, then an amount equal to the excess of such Purchaser’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of ADSs so purchased (including brokerage commissions and other out-of-pocket expenses, if any) (the “Buy-In Price”) over the product of (A) such number of Warrant ADSs underlying the ADS Warrants that the Company was required to deliver to such Purchaser by the Legend Removal Date multiplied by (B) the lowest closing sale price of the ADSs on any Trading Day during the period commencing on the date of the delivery by such Purchaser to the Company of the applicable Warrant ADSs underlying the ADS Warrants (as the case may be) and ending on the date of such delivery and payment under this Section 4.1(d).

(e) The Shares, the ADSs, the Pre-Funded Warrants, and the Warrant Securities underlying the Pre-Funded Warrants shall be issued free of legends.

4.2 Furnishing of Information.

(a) Until the earliest of the time that (i) no Purchaser owns any Warrants or (ii) the Warrants have expired, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act, even if the Company is not then subject to the reporting requirements of the Exchange Act.

(b) At any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of the Warrant ADSs underlying the ADS Warrants (assuming cashless exercise of the Warrants and that such Warrant ADSs and Warrant Shares are not then held by an Affiliate of the Company) may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, if the

36

Company (i) shall fail for any reason to satisfy the current public information requirement under Rule 144(c) or (ii) has ever been an issuer described in Rule 144(i)(1)(i) or becomes an issuer in the future, and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”) then, in addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the Warrant ADSs, an amount in cash equal to two percent (2.0%) of the aggregate exercise price of such Purchaser’s Warrants on the day of a Public Information Failure and on every thirtieth (30^th) day (pro rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time that such public information is no longer required for the Purchaser to transfer the Warrant ADSs underlying the ADS Warrants pursuant to Rule 144. The payments to which a Purchaser shall be entitled pursuant to this Section 4.2(b) are referred to herein as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3^rd) Business Day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Public Information Failure, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

4.3 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the ADS Warrants, Warrant ADSs issuable upon exercise of the ADSs Warrants or Warrant Shares issuable upon exercise of the ADS Warrants or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

4.4 Securities Laws Disclosure; Publicity. The Company shall (a) by 8:00 a.m. (New York City time) on September 30, 2019, issue a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Current Report on Form 6-K, including the Transaction Documents as exhibits thereto, with the Commission within one (1) Trading Day following the date hereof. From and after the issuance of such press release, the Company represents to the Purchasers that it shall have publicly disclosed all material, non-public information delivered to any of the Purchasers by the Company or any of its Subsidiaries, or any of their respective officers, directors, employees or agents in connection with the transactions contemplated by the Transaction Documents. In addition, effective upon the issuance of such press release, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates on the

37

one hand, and any of the Purchasers or any of their respective Affiliates on the other hand, shall terminate. The Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication. Notwithstanding the foregoing, nothing herein shall prevent the Company from disclosing any information relating to this Agreement, the Transaction Documents or the transactions contemplated hereby and thereby in any filing with the Commission, ASX or any other regulatory agency or Trading Market (a) as required by federal securities law in connection with the filing of final Transaction Documents with the Commission and (b) to the extent such disclosure is required by law or Trading Market regulations, as determined by the Company in its sole discretion; provided that in the case of clause (b), the Company shall use commercially reasonable efforts to provide the Purchasers with prior notice of such disclosure.

4.5 Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.

4.6 Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, which shall be disclosed pursuant to Section 4.4, the Company covenants and agrees that neither the Company, nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that constitutes, or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have consented to the receipt of such information and agreed with the Company to keep such information confidential. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company. To the extent that the Company delivers any material, non-public information to a Purchaser without such Purchaser’s consent, the Company hereby covenants and agrees that such Purchaser shall not have any duty of confidentiality to the Company, any of its Subsidiaries, or any of their respective officers, directors, agents, employees or Affiliates, or a duty to the Company, any of its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates not to trade on the basis of, such material, non-public information, provided that such Purchaser shall remain subject to applicable law. To the extent that any notice provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 6-K. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

38

4.7 Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder for working capital purposes and shall not use such proceeds: (a) for the satisfaction of any portion of the Company’s debt (other than payment of trade payables in the ordinary course of the Company’s business and prior practices), (b) for the redemption of any Ordinary Shares or Ordinary Share Equivalents, (c) for the settlement of any outstanding litigation or (d) in violation of FCPA or OFAC regulations.

4.8 Indemnification of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is solely based upon a material breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party which is finally judicially determined to constitute fraud, gross negligence or willful misconduct) or (c) in connection with any registration statement of the Company providing for the resale by the Purchasers of the Warrant Shares issued and issuable upon exercise of the ADS Warrants, the Company will indemnify each Purchaser Party, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses, as incurred, arising out of or relating to (i) any untrue or alleged untrue statement of a material fact contained in such registration statement, any prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding such Purchaser Party furnished in writing to the Company by such Purchaser Party expressly for use therein, or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder in connection therewith. If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any

39

Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (x) the employment thereof has been specifically authorized by the Company in writing, (y) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (z) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (1) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (2) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 4.8 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law.

4.9 Reservation of Ordinary Shares. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of Ordinary Shares for the purpose of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants.

4.10 Listing of Securities. The Company hereby agrees to use its best efforts to maintain the listing or quotation of the ADSs on the Trading Market on which ADSs are currently listed, and as soon as reasonably practical following the Closing or, with respect to the ASX only, the exercise of any Warrant, the Company shall apply to list or quote all of the Shares, ADSs, Warrant Shares and Warrant ADSs on such Trading Market and promptly pursue the listing of all of the Shares, ADSs, Warrant Shares and Warrant ADSs on such Trading Market. The Company further agrees, (i) if the Company applies to have the Ordinary Shares traded on any other Trading Market, it will then include in such application all of the Shares and will take such other action as is necessary to cause all of the Shares to be listed or quoted on such other Trading Market as promptly as possible; and (ii) if the Company applies to have the ADSs traded on any other Trading Market, it will then include in such application all of the ADSs, Warrant Shares and Warrant ADSs and will take such other action as is necessary to cause all of the ADSs, Warrant Shares and Warrant ADSs to be listed or quoted on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue the listing and trading of its Ordinary Shares on a Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market; provided that the Purchasers acknowledge the Company’s receipt of a deficiency notice from the Nasdaq Stock Market as described in the Current Report on Form 6-K filed by the Company with the Commission on July 25, 2019. The Company agrees to maintain the eligibility of the Securities for electronic transfer through the Depository Trust Company or another established clearing corporation, including, without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing corporation in connection with such electronic transfer. In addition, the Company shall hold a vote for the purpose of

40

obtaining Shareholder Approval as soon as practical following the Closing Date, and in any event on or before the three month anniversary of the Closing Date, with the recommendation of the Company’s Board of Directors that such proposal be approved, and the Company shall solicit proxies from its shareholders in connection therewith in the same manner as all other management proposals in such proxy statement and all management-appointed proxyholders shall vote their proxies in favor of such proposal. If the Company does not obtain Shareholder Approval at the next shareholder meeting, the Company shall call a meeting every four months thereafter to seek Shareholder Approval until Shareholder Approval is obtained. Each Purchaser agrees to vote any Ordinary Shares held by it in favor of Shareholder Approval.

4.11 Subsequent Equity Sales.

(a) From the date hereof until the later of (i) forty-five (45) days following the Closing Date, and (ii) the date Shareholder Approval is received and deemed effective, neither the Company nor any Subsidiary shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any ADSs, Ordinary Shares or Ordinary Share Equivalents.

(b) From the date hereof until 180 days following the Closing Date, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of Ordinary Shares, ADSs or Ordinary Share Equivalents (or a combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Ordinary Shares or ADSs either (A) at a conversion price, exercise price or exchange rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Ordinary Shares or ADSs at any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Ordinary Shares or ADSs or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit, whereby the Company may issue securities at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.

(c) Notwithstanding the foregoing, this Section 4.11 shall not apply in respect of an Exempt Issuance, except that no Variable Rate Transaction shall be an Exempt Issuance.

4.12 Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of the Transaction Documents unless the same consideration is also offered to all of the parties to the Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise.

41

4.13 Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release as described in Section 4.4, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information included in the Disclosure Schedules. Notwithstanding the foregoing and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4 and (iii) no Purchaser shall have any duty of confidentiality or duty not to trade in the securities of the Company to the Company or its Subsidiaries after the issuance of the initial press release as described in Section 4.4. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement.

4.14 Capital Changes. Until the one year anniversary of the Closing Date, the Company shall not undertake a reverse or forward stock split or reclassification of the Ordinary Shares without the prior written consent of the majority of the Purchasers, based on initial Subscription Amounts hereunder, other than a reverse or forward stock split or reclassification of the Ordinary Shares that is required in order to satisfy any requirements of Exchange Rules (including without limitation the Nasdaq Stock Market requirement to maintain a minimum trading price of the ADSs).

4.15 Exercise Procedures. Except as required by Section 4.1 hereof, the form of Notice of Exercise included in the Warrants set forth the totality of the procedures required of the Purchasers in order to exercise the Warrants. No additional legal opinion, other information or instructions shall be required of the Purchasers to exercise their Warrants, except as required by this Agreement. Without limiting the preceding sentences, no ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required in order to exercise the Warrants. The Company shall honor exercises of the Warrants and shall deliver Warrant Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.

42

4.16 Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the ADS Warrants and the Warrant Shares issuable upon exercise of the ADS Warrants as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the ADS Warrants and the Warrant Shares issuable upon exercise of the ADS Warrants for sale to the Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of any Purchaser.

4.17 ASX Cleansing Statement. The Company undertakes to lodge with the ASX a Cleansing Statement and an ASX Appendix 3B in respect of Ordinary Shares underlying the Securities on the Closing Date, but in no event later than 10:00 a.m., Sydney time, on the ASX Trading Day immediately following the Closing Date, which shall contain the information that is sufficient to permit subsequent re-sale on ASX of all of the Ordinary Shares issued to the Purchasers. Upon the lodging of an Appendix 3B and the Cleansing Statement, the Shares will be freely tradable on the ASX. If (i) the Company fails to lodge a Warrant Prospectus in respect of the ADS Warrants to be issued following Shareholder Approval; (ii) is unable to issue the Warrants pursuant to that Warrant Prospectus for any reason; or (iii) ASIC Corporations (Sale Offers That Do Not Need Disclosure) Instrument 2016/80 or a like instrument is no longer in force to enable the on-sale of the relevant Warrant Shares by the Purchasers, the Company must use its best efforts to ensure that it lodges with ASX a notice in accordance with section 708A(5)(e) of the Corporations Act within 5 Business Days of the issue of any Warrant Shares, provided that, if for any reason within that 5 Business Days the Company does not lodge a Cleansing Statement in compliance with the requirements of section 708A(5)(e) of the Corporations Act in respect of an issue of Ordinary Shares issued on exercise of Warrants, the Company shall, at its own expense and as soon as practicable, do everything necessary to ensure that such Warrant Shares are able to be freely traded on ASX in compliance with the ASX Listing Rules and the Corporations Act, including obtaining an exemption from the ASIC or the lodging of a disclosure document with ASIC in accordance with the requirements of Chapter 6D of the Corporations Act.

4.18 Payments and Taxes. All payments by the Company due under any Transaction Document shall be made by the Company and the Company agrees that all amounts payable under any Transaction Document are exclusive of any current or future tax or any other fees, expenses, assessment or charges of any kind (including but not limited to income tax, value added tax, goods and services tax, transfer tax, business tax, foreign enterprise income tax, consumption tax, securities transaction tax, withholding tax, stamp duty or other documentary taxes or charges, and any other taxes and charges, and interest and penalties thereon) imposed by any federal, state, territorial or local government of Australia, or any political subdivision or taxing authority in any such jurisdiction (collectively, “Taxes,” which for the avoidance of doubt, does not include income tax) and all amounts shall be paid free and clear of any deduction or withholding. The Company agrees that it shall be responsible for all Taxes imposed on the Company as well as all applicable compliance and regulatory obligations which may arise from

43

or in connection with this Agreement. If any Taxes shall be due, or if the Company shall be required by applicable law to make any deduction or withholding on account of any Taxes, or if any Tax is required to be paid by any Purchaser as a result of the transactions hereunder, the Company agrees to pay to such Purchaser such additional amounts as shall be required so that the net amount received by such Purchaser from the Company after such deduction, withholding or payment shall equal the amount otherwise due to such Purchaser hereunder. The Company shall promptly deliver to each Purchaser all official tax receipts evidencing payment of the Taxes. Each Purchaser agrees to provide the Company with any and all forms or other documentation or information that the Company reasonably requests to enable the Company to minimize the amount of any such Taxes. The Company will indemnify each Purchaser and hold it harmless against any Taxes on the creation, issuance and sale of the Securities to each Purchaser and on the execution and delivery of this Agreement and any interest and penalties thereon.

4.19 Compliance with Anti-Bribery Laws, Money Laundering Laws and Sanctions. The Company will not, and the Company will procure that each of its Subsidiaries , any of their respective affiliates and any Person acting on its or their behalf will not, (i) violate any of the Anti-Bribery Laws, Money Laundering Laws or Sanctions or (ii) directly or indirectly use the proceeds from the offering of the Securities, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other Person or entity, for the purpose of financing or facilitating the business or the activities of any Person, or in any country or territory that, at the time of such financing or facilitation, is subject to any Sanctions, or in any other manner that will result in a violation of Sanctions by any Person.

4.20 Payment of Expenses Pursuant to Deposit Agreement and ADSs. The Company hereby agrees to pay on behalf of each Purchaser, or to reimburse each Purchaser for, all fees and expenses incurred by such Purchaser pursuant to the Deposit Agreement, including Section 5.09 of the Deposit Agreement and Section 7 of the ADRs, in connection with the issuance of the Securities, including any fees incurred by such Purchaser for holding ADSs with respect to the Securities. In addition, if the dollar trading volume of the Ordinary Shares on the ASX (the “ASX Volume”) equals or exceeds 70% of the aggregate dollar trading volume of the Ordinary Shares and ADSs on ASX and the Trading Market in the United States (the “Aggregate Volume”) as an average during any period of 5 consecutive Trading Days as reported on Bloomberg L.P., the Company shall pay on behalf of each Purchaser, or reimburse each Purchaser for, all fees and expenses incurred by such Purchaser for converting ADSs to Ordinary Shares with respect to the Securities until such date as the ASX Volume is less than 70% of the Aggregate Volume on each Trading Day for a period of 30 consecutive Trading Days as reported on Bloomberg L.P. For purposes of clarity, if the ASX Volume equals or exceeds 70% of the Aggregate Volume during a subsequent period as described in the previous sentence, the reimbursement obligations shall again apply as provided in the previous sentence.

4.21 Lock-Up Agreements. The Company shall enforce the terms of the Lock-Up Agreements and not agree to any amendment to, or modification of, the Lock-Up Agreements absent the prior written consent of the Purchasers.

44

4.22 Registration Statement. As soon as practicable (and in any event within 45 calendar days of the date of this Agreement), the Company shall file a registration statement on Form F-3 (or other appropriate form if the Company is not then F-3 eligible) providing for the resale by the Purchasers of the Warrant Shares issued and issuable upon exercise of the Warrants. The Company shall use commercially reasonable efforts to cause such registration to become effective within 181 days following the Closing Date and to keep such registration statement effective at all times until no Purchaser owns any Warrants or Warrant Shares issuable upon exercise thereof.

4.23 Delivery of Series 2 ADS Warrants; 3(a)(9) Exchange. A Series 2 ADS Warrant registered in the name of each Purchaser to purchase up to a number of ADSs equal to 100% of such Purchaser’s Subscription Amount divided by the Per ADS Purchase Price, with an exercise price equal to $0.70 per ADS, subject to adjustment therein, shall be delivered on or before the second Trading Day after Shareholder Approval is received and deemed effective; provided, however, at the election of each Purchaser at any time on or after the date that Shareholder Approval is received and deemed effective, solely with respect to itself and not with respect to any other Purchaser, such Purchaser shall be entitled to exchange, in accordance with Section 3(a)(9) of the Securities Act, such Purchaser’s Series 1 ADS Warrant for the Series 2 ADS Warrant, and the holding period of such Series 2 ADS Warrants being delivered hereby may be tacked on to the holding period of the Series 1 ADS Warrants for purposes of Rule 144. The Company agrees not to take any position contrary to this Section 4.23.

4.24 QEF Election. Upon request of any U.S. Purchaser at any time and from time to time, the Company will promptly provide the information necessary for such U.S. Purchaser to make a QEF Election with respect to the Company and will use reasonable best efforts to cause each direct and indirect subsidiary that the Company controls that is a PFIC to provide such information with respect to such Subsidiary.

No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

5.9 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Action or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such Action or Proceeding is improper or is an inconvenient venue for such Proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such Action or Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.

5.10 Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.

5.11 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

5.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

47

5.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights; provided, however, that in the case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return any ADSs subject to any such rescinded exercise notice concurrently with the return to such Purchaser of the aggregate exercise price paid to the Company for such shares and the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant (including, issuance of a replacement warrant certificate evidencing such restored right).

5.14 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

5.15 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any such obligation the defense that a remedy at law would be adequate.

5.16 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

48

5.17 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each Purchaser and its respective counsel have chosen to communicate with the Company through EGS. EGS does not represent any of the Purchasers and only represents the Placement Agent. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers. It is expressly understood and agreed that each provision contained in this Agreement and in each other Transaction Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the Purchasers.

5.18 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts are due and payable shall have been canceled.

5.19 Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

5.20 Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto.

5.21 WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.

49

5.22 Currency Unless otherwise indicated, all dollar amounts referred to in this Agreement are in United States Dollars (“US Dollars”). All amounts owing under this Agreement or any Transaction Document shall be paid in US Dollars. All amounts denominated in other currencies shall be converted in the US Dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange Rate” means, in relation to any amount of currency to be converted into US Dollars pursuant to this Agreement, the US Dollar exchange rate as published in the Wall Street Journal (NY edition) on the relevant date of calculation.

Exhibit 99.3

PRE-FUNDED AMERICAN DEPOSITARY SHARES PURCHASE WARRANT

BENITEC BIOPHARMA LIMITED

THIS PRE-FUNDED AMERICAN DEPOSITARY SHARES PURCHASE WARRANT (the “Warrant”) certifies that, for value received, ____________ or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the date hereof (the “Initial Exercise Date”) and until this Warrant is exercised in full (the “Termination Date”), to subscribe for and purchase from Benitec Biopharma Limited, an Australian public company incorporated under the laws of the Commonwealth of Australia (the “Company”), up to ______ American Depositary Shares (“ADSs”), each ADS representing ______ ordinary shares, no par value, of the Company (the “Ordinary Shares”) (as subject to adjustment hereunder, the “Warrant Shares”) (the ADSs issuable hereunder, the “Warrant ADSs”). The purchase price of one ADS under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

Section 1. Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated as of September __, 2019, among the Company and purchasers signatory thereto.

Section 2. Exercise.

a) Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company or the Depositary, as applicable, of a duly executed facsimile copy or PDF copy submitted by electronic (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (“Notice of Exercise”). Within two (2) Trading Days following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the ADSs specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank, unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant ADSs available hereunder and the Warrant has been exercised in full, in which case the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant ADSs available hereunder shall have the effect of lowering the outstanding number of Warrant ADSs purchasable hereunder in an amount equal to the applicable number of Warrant ADSs purchased. The Holder and the Company shall maintain records showing the number of

1

Warrant ADSs purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant ADSs hereunder, the number of Warrant ADSs available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

b) Exercise Price. The aggregate exercise price of this Warrant, except for a nominal exercise price of $0.0001 per Warrant ADS, was pre-funded to the Company on or prior to the Initial Exercise Date and, consequently, no additional consideration (other than the nominal exercise price of $0.0001 per Warrant ADS) shall be required to be paid by the Holder to any Person to effect any exercise of this Warrant. The Holder shall not be entitled to the return or refund of all, or any portion, of such pre-paid aggregate exercise price under any circumstance or for any reason whatsoever, including in the event this Warrant shall not have been exercised prior to the Termination Date. The remaining unpaid exercise price per Warrant ADS under this Warrant shall be $0.0001, subject to adjustment hereunder (the “Exercise Price”).

c) Cashless Exercise. This Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where::

2

If Warrant ADSs are issued in such a cashless exercise, the parties acknowledge and agree that, in accordance with Section 3(a)(9) of the Securities Act, the Warrant ADSs shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any position contrary to this Section 2(c).

“Bid Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADS is then listed or quoted on a Trading Market, the bid price of the ADS for the time in question (or the nearest preceding date) on the Trading Market on which the ADS is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the ADS for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the ADS are then reported in The Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per ADS so reported, or (d) in all other cases, the fair market value of an ADS as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADS is then listed or quoted on a Trading Market, the daily volume weighted average price of the ADS for such date (or the nearest preceding date) on the Trading Market on which the ADS is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the ADS for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the ADS are then reported in The Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per ADS so reported, or (d) in all other cases, the fair market value of an ADS as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

Notwithstanding anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant to this Section 2(c).

3

d) Mechanics of Exercise.

i. Delivery of Warrant ADSs Upon Exercise. Warrant ADSs purchased hereunder shall be transmitted by the Depositary to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company (or another established clearing corporation performing similar functions) through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant ADSs to or resale of the Warrant ADSs by the Holder or (B) this Warrant is being exercised via cashless exercise and otherwise by physical delivery of the Warrant Shares, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant ADSs to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is two (2) Trading Days after the delivery to the Company of the Notice of Exercise (such date, the “Warrant ADS Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant ADSs with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant ADSs, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within two (2) Trading Days. If the Company fails for any reason to deliver to the Holder the Warrant ADSs subject to a Notice of Exercise by the Warrant ADS Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant ADSs subject to such exercise (based on the VWAP of the ADS on the date of the applicable Notice of Exercise), $10 per Trading Day for each Trading Day after such Warrant ADS Delivery Date until such Warrant ADSs are delivered or Holder rescinds such exercise. The Company agrees to maintain a registrar (which can be the Depositary) that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant, at the time of delivery of the Warrant ADSs, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant ADSs called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

ii. Rescission Rights. If the Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs pursuant to Section 2(d)(i) by the Warrant ADS Delivery Date, then the Holder will have the right to rescind such exercise.

4

iii. Compensation for Buy-In on Failure to Timely Deliver Warrant ADSs Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs in accordance with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant ADS Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, ADSs to deliver in satisfaction of a sale by the Holder of the Warrant ADSs which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the ADSs so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant ADSs that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant ADSs for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of ADSs that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases ADSs having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of Warrants with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver ADSs upon exercise of the Warrant as required pursuant to the terms hereof.

iv. No Fractional ADSs or Scrip. No fractional ADSs or scrip representing fractional ADSs shall be issued upon the exercise of this Warrant. As to any fraction of an ADS which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

v. Charges, Taxes and Expenses. Issuance of Warrant ADSs shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant ADSs, all of which taxes and expenses shall be paid by the Company, and such Warrant ADSs shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided,

5

however, that in the event that Warrant ADSs are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Depositary fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant ADSs.

vi. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

vii. ASX Requirements. On or before the Warrant ADS Delivery Date, the Company shall, subject to the Corporations Act and the ASX Listing Rules (as defined below):

e) Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of Ordinary Shares beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of Ordinary Shares held by the Holder and its Attribution Parties plus the number of Ordinary Shares underlying such Warrant ADSs issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of Ordinary Shares underlying Warrant ADSs which would

6

be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Ordinary Share Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding Ordinary Shares, a Holder may rely on the number of outstanding Ordinary Shares as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Depositary setting forth the number of Ordinary Shares outstanding. Upon the written or oral request of a Holder, the Company shall within one Trading Day confirm orally and in writing to the Holder the number of Ordinary Shares then outstanding. In any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding Ordinary Shares was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, at the election of a Holder prior to the date of issuance of the Warrants, 9.99%) of the number of Ordinary Shares outstanding immediately after giving effect to the issuance of Ordinary Shares underlying the Warrant ADSs issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of Ordinary Shares outstanding immediately after giving effect to the issuance of Ordinary Shares upon exercise

7

of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61^st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

f) ASX Filings. The Company will ensure that it applies to ASX for official quotation (as that expression is used in the ASX Listing Rules) of the Ordinary Shares issued on the exercise of the Warrants in the same class and on the same terms as all other Ordinary Shares quoted on ASX pursuant to ASX Listing Rule 2.7 immediately on issue of those Ordinary Shares.

Section 3. Certain Adjustments. Notwithstanding any provision of this Section 3 or generally in this Warrant, the Exercise Price per Warrant, the number of ADSs the subject of each Warrant, or the number of Warrants held shall be subject to adjustment from time to time after the Issuance Date in accordance with the Official Listing Rules of the Australian Securities Exchange (“ASX Listing Rules”) upon the occurrence of certain events described in this Section 3 or, if the ASX Listing Rules are amended after the date of issue of the Warrants, in accordance with the Company’s obligations under the ASX Listing Rules to the extent those obligations are modified by the amendment.

a) Subdivision or Combination; Capital Distributions; Other Adjustments.

i. In a consolidation of the Company’s ordinary capital – the number of Warrants will be consolidated in the same ratio as the ordinary capital and the Exercise Price will be amended in inverse proportion to that ratio.

ii. In a sub-division of the Company’s ordinary capital – the number of Warrants will be sub-divided in the same ratio as the ordinary capital and the Exercise Price will be amended in inverse proportion to that ratio.

iii. In a return of capital on Ordinary Shares – the number of Warrants will remain the same, and the Exercise Price of each Warrant will be reduced by the same amount as the amount of cash or value of shares, securities, or other property returned in relation to each Ordinary Share, multiplied by the number of Ordinary Shares represented by each ADS (the “ADS Ratio”).

iv. In a reduction of the Company’s capital by a cancellation of paid up capital that is lost or not represented by available assets where no securities are cancelled – the number of Warrants and the Exercise Price of each Warrant will remain unaltered.

8

v. In a pro rata cancellation of the Company’s capital on Ordinary Shares – the number of Warrants will be reduced in the same ratio as the ordinary capital and the Exercise Price of each Warrant will be amended in inverse proportion to that ratio.

vi. In any other case – the number of Warrants or the Exercise Price, or both, will be reorganized in accordance with the ASX Listing Rules so that the holder of the Warrants will not receive a benefit that holders of Ordinary Shares do not receive.

b) Bonus Shares and Share Dividends. If there is a pro-rata bonus issue, or a pro-rata dividend to be paid only in Ordinary Shares, to the holders of issued Ordinary Shares, the number of Warrant ADSs upon exercise will be increased by the number of ADSs which the holder of the Warrant would have received if the Warrant had been exercised before the record date for the bonus issue or share dividend.

c) Pro Rata Distributions. If there is a pro-rata offer of Ordinary Shares (other than a bonus issue) to the holders of Ordinary Shares, the Exercise Price will be reduced in accordance with the following formula:

O is the old Exercise Price

E is the number of Ordinary Shares underlying the Warrant ADSs into which one Warrant is exercisable

P is the volume weighted average market price per Ordinary Share on the ASX over the 5 ASX trading days ending on the ASX trading day before the ex rights or ex entitlement date for the pro rata issue

S is the subscription price for one Ordinary Share under the pro rata offer

D is the dividend (if any) due but not yet paid on an existing Ordinary Shares which will not be paid on the new Ordinary Shares to be issued in the pro rata issue

N is the number of Ordinary Shares that must be held on the record date for the pro rata issue to receive a right or entitlement to subscribe for one new Ordinary Share.

9

For the avoidance of doubt, if the formula results in no decrease in the Exercise Price then the Exercise Price remains unchanged.

d) Change in ADS Ratio. If after the Issuance Date the ADS Ratio is increased or reduced, then the number of Warrant ADSs to be provided on exercise of a Warrant will be reduced or increased (respectively) in inverse proportion to the change in the ADS Ratio Ordinary Shares per ADS and the Exercise Price per Warrant will be increased or reduced (respectively) in proportion to the change in Ordinary Shares per ADS, so that the total number or Warrant Shares underlying the Warrants and the aggregate Exercise Price for all Warrants remain unchanged.

e) Fundamental Transaction. If, at any time while this Warrant is outstanding,

10

then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share underlying the Warrant ADSs that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of capital stock of the successor or acquiring corporation or of the Company (if the Company is the surviving corporation) and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of Ordinary Shares underlying the Warrant ADSs for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one Ordinary Share in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Ordinary Shares are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.

The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the surviving entity (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the Ordinary Shares underlying the Warrant ADSs acquirable and receivable upon exercise of this Warrant (without regard to any limitation in Section 2(e) on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the Ordinary Shares underlying the Warrant ADSs pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

11

f) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of Ordinary Shares deemed to be issued and outstanding as of a given date shall be the sum of the number of Ordinary Shares (excluding treasury shares, if any) issued and outstanding.

g) Notice to Holder.

i. Adjustment. Whenever the Exercise Price, the number of ADSs the subject of each Warrant, or the number of Warrants is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrants or the number of ADSs the subject of each Warrant and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Ordinary Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Ordinary Shares, (C) the Company shall authorize the granting to all holders of the Ordinary Shares rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Ordinary Shares, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Ordinary Shares are converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Ordinary Shares of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Ordinary Shares of record shall be entitled to exchange their Ordinary Shares for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that

12

any notice provided in this Warrant constitutes, or contains, material non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice, or such material non-public information included in such notice, with the Commission pursuant to a Current Report on Form 6-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4. Transfer of Warrant.

a) Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant ADSs without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Initial Exercise Date and shall be identical with this Warrant except as to the number of Warrant ADSs issuable pursuant thereto.

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

13

Section 5. Miscellaneous.

a) Currency. Unless otherwise indicated, all dollar amounts referred to in this Warrant are in United States Dollars (“US Dollars”). All amounts owing under this Warrant shall be paid in US Dollars. All amounts denominated in other currencies shall be converted in the US Dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange Rate” means, in relation to any amount of currency to be converted into US Dollars pursuant to this Warrant, the US Dollar exchange rate as published in the Wall Street Journal (NY edition) on the relevant date of calculation.

b) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.

c) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant ADSs, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

d) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

e) Authorized Shares.

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Ordinary Shares a sufficient number of shares to provide for the issuance of the Warrant ADSs and the underlying Ordinary Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant ADSs upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant ADSs and the underlying Ordinary Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the ADS or Ordinary Shares may be listed. The Company covenants that all Warrant ADSs

14

and the underlying Ordinary Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant ADSs in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant ADSs above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant ADSs and the underlying Ordinary Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant ADSs for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

f) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement.

g) Restrictions. The Holder acknowledges that the Warrant ADSs and the underlying Ordinary Shares acquired upon the exercise of this Warrant, if not registered and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal or foreign securities laws.

h) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

15

i) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

j) Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant ADSs, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any ADS or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

k) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

l) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant ADSs.

m) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

n) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

o) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

THIS SERIES 2 AMERICAN DEPOSITARY SHARES PURCHASE WARRANT (the “Warrant”) certifies that, for value received, ____________ or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the date hereof (the “Initial Exercise Date”) and on or prior to _______ __, 20__¹ (the “Termination Date”, but not thereafter, to subscribe for and purchase from Benitec Biopharma Limited, an Australian public company incorporated under the laws of the Commonwealth of Australia (the “Company”), up to one (1) American Depositary Share (“ADSs”), each ADS representing twenty (20) ordinary shares, no par value, of the Company (the “Ordinary Shares”) (as subject to adjustment hereunder, the “Warrant Shares”) (the ADSs issuable hereunder, the “Warrant ADSs”). The purchase price of one ADS under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

Section 1. Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated as of September     , 2019, among the Company and purchasers signatory thereto.

Section 2. Exercise.

a) Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company or the Depositary, as applicable, of a duly executed facsimile copy or PDF copy submitted by electronic (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (“Notice of Exercise”). Within two (2) Trading Days following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the ADSs specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank, unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant ADSs available hereunder and the Warrant has been exercised in full, in which case the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant ADSs available hereunder shall have the effect of lowering the outstanding number of Warrant ADSs purchasable hereunder in an amount equal to the applicable number of Warrant ADSs purchased. The Holder and the Company shall maintain records showing the number of Warrant ADSs purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant ADSs hereunder, the number of Warrant ADSs available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

b) Exercise Price. The exercise price per ADS under this Warrant shall be $0.70, subject to adjustment hereunder (the “Exercise Price”).

c) Cashless Exercise. If at any time after the six-month anniversary of the Issue Date, either (i) there is no effective registration statement registering, or no current prospectus available for, the resale of the Warrant ADSs by the Holder or (ii) the Depositary or the Company indicates to the Holder at any time that the Warrant ADSs issuable upon exercise of this Warrant will not be issued legend-free (without requiring proof of sale of the Warrant ADSs by the Holder) or not delivered via DWAC (as defined below), then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant ADSs equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

2

If Warrant ADSs are issued in such a cashless exercise, the parties acknowledge and agree that, in accordance with Section 3(a)(9) of the Securities Act, the Warrant ADSs shall take on the characteristics of the Warrants being exercised, and the holding period of the Warrant ADSs being issued may be tacked on to the holding period of this Warrant. The Company agrees not to take any position contrary to this Section 2(c).

“Bid Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADS is then listed or quoted on a Trading Market, the bid price of the ADS for the time in question (or the nearest preceding date) on the Trading Market on which the ADS is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the ADS for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the ADS are then reported in The Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per ADS so reported, or (d) in all other cases, the fair market value of an ADS as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the ADS is then listed or quoted on a Trading Market, the daily volume weighted average price of the ADS for such date (or the nearest preceding date) on the Trading Market on which the ADS is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the ADS for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the ADS is not then listed or quoted for

3

trading on OTCQB or OTCQX and if prices for the ADS are then reported in The Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per ADS so reported, or (d) in all other cases, the fair market value of an ADS as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

Notwithstanding anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant to this Section 2(c).

d) Mechanics of Exercise.

i. Delivery of Warrant ADSs Upon Exercise. Warrant ADSs purchased hereunder shall be transmitted by the Depositary to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company (or another established clearing corporation performing similar functions) through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant ADSs to or resale of the Warrant ADSs by the Holder or (B) the Warrant ADSs are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant to Rule 144 (assuming cashless exercise of the Warrants and that such Warrant ADSs and Warrant Shares are not then held by an Affiliate of the Company), and otherwise by physical delivery of the Warrant Shares, registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant ADSs to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is two (2) Trading Days after the delivery to the Company of the Notice of Exercise (such date, the “Warrant ADS Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant ADSs with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant ADSs, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within two (2) Trading Days. If the Company fails for any reason to deliver to the Holder the Warrant ADSs subject to a Notice of Exercise by the Warrant ADS Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant ADSs subject to such exercise (based on the VWAP of the ADS on the date of the applicable Notice of Exercise), $10 per Trading Day for each Trading Day after such Warrant ADS Delivery Date until such Warrant ADSs are delivered or Holder rescinds such exercise. The Company agrees to maintain a registrar (which can be the

4

Depositary) that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant, at the time of delivery of the Warrant ADSs, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant ADSs called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

ii. Rescission Rights. If the Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs pursuant to Section 2(d)(i) by the Warrant ADS Delivery Date, then the Holder will have the right to rescind such exercise.

iii. Compensation for Buy-In on Failure to Timely Deliver Warrant ADSs Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Depositary to transmit to the Holder the Warrant ADSs in accordance with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant ADS Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, ADSs to deliver in satisfaction of a sale by the Holder of the Warrant ADSs which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the ADSs so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant ADSs that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant ADSs for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of ADSs that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases ADSs having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of Warrants with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver ADSs upon exercise of the Warrant as required pursuant to the terms hereof.

5

iv. No Fractional ADSs or Scrip. No fractional ADSs or scrip representing fractional ADSs shall be issued upon the exercise of this Warrant. As to any fraction of an ADS which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

v. Charges, Taxes and Expenses. Issuance of Warrant ADSs shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant ADSs, all of which taxes and expenses shall be paid by the Company, and such Warrant ADSs shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Warrant ADSs are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Depositary fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant ADSs.

vi. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

vii. ASX Requirements. On or before the Warrant ADS Delivery Date, the Company shall, subject to the Corporations Act and the ASX Listing Rules (as defined below):

6

e) Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of Ordinary Shares beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number of Ordinary Shares held by the Holder and its Attribution Parties plus the number of Ordinary Shares underlying such Warrant ADSs issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of Ordinary Shares underlying Warrant ADSs which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Ordinary Share Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding Ordinary Shares, a Holder may rely on the number of outstanding Ordinary Shares as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent

7

written notice by the Company or the Depositary setting forth the number of Ordinary Shares outstanding. Upon the written or oral request of a Holder, the Company shall within one Trading Day confirm orally and in writing to the Holder the number of Ordinary Shares then outstanding. In any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding Ordinary Shares was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, at the election of a Holder prior to the date of issuance of the Warrants, 9.99%) of the number of Ordinary Shares outstanding immediately after giving effect to the issuance of Ordinary Shares underlying the Warrant ADSs issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of Ordinary Shares outstanding immediately after giving effect to the issuance of Ordinary Shares upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61^st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

f) ASX Filings. The Company will ensure that it applies to ASX for official quotation (as that expression is used in the ASX Listing Rules) of the Ordinary Shares issued on the exercise of the Warrants in the same class and on the same terms as all other Ordinary Shares quoted on ASX pursuant to ASX Listing Rule 2.7 immediately on issue of those Ordinary Shares.

Section 3. Certain Adjustments. Notwithstanding any provision of this Section 3 or generally in this Warrant, the Exercise Price per Warrant, the number of ADSs the subject of each Warrant, or the number of Warrants held shall be subject to adjustment from time to time after the Issuance Date in accordance with the Official Listing Rules of the Australian Securities Exchange (“ASX Listing Rules”) upon the occurrence of certain events described in this Section 3 or, if the ASX Listing Rules are amended after the date of issue of the Warrants, in accordance with the Company’s obligations under the ASX Listing Rules to the extent those obligations are modified by the amendment.

a) Subdivision or Combination; Capital Distributions; Other Adjustments.

i. In a consolidation of the Company’s ordinary capital – the number of Warrants will be consolidated in the same ratio as the ordinary capital and the Exercise Price will be amended in inverse proportion to that ratio.

8

ii. In a sub-division of the Company’s ordinary capital – the number of Warrants will be sub-divided in the same ratio as the ordinary capital and the Exercise Price will be amended in inverse proportion to that ratio.

iii. In a return of capital on Ordinary Shares – the number of Warrants will remain the same, and the Exercise Price of each Warrant will be reduced by the same amount as the amount of cash or value of shares, securities, or other property returned in relation to each Ordinary Share, multiplied by the number of Ordinary Shares represented by each ADS (the “ADS Ratio”).

iv. In a reduction of the Company’s capital by a cancellation of paid up capital that is lost or not represented by available assets where no securities are cancelled – the number of Warrants and the Exercise Price of each Warrant will remain unaltered.

v. In a pro rata cancellation of the Company’s capital on Ordinary Shares – the number of Warrants will be reduced in the same ratio as the ordinary capital and the Exercise Price of each Warrant will be amended in inverse proportion to that ratio.

vi. In any other case – the number of Warrants or the Exercise Price, or both, will be reorganized in accordance with the ASX Listing Rules so that the holder of the Warrants will not receive a benefit that holders of Ordinary Shares do not receive.

b) Bonus Shares and Share Dividends. If there is a pro-rata bonus issue, or a pro-rata dividend to be paid only in Ordinary Shares, to the holders of issued Ordinary Shares, the number of Warrant ADSs upon exercise will be increased by the number of ADSs which the holder of the Warrant would have received if the Warrant had been exercised before the record date for the bonus issue or share dividend.

c) Pro Rata Distributions. If there is a pro-rata offer of Ordinary Shares (other than a bonus issue) to the holders of Ordinary Shares, the Exercise Price will be reduced in accordance with the following formula:

        N + 1

Where:

O’ is the new Exercise Price

O is the old Exercise Price

E is the number of Ordinary Shares underlying the Warrant ADSs into which one Warrant is exercisable

9

P is the volume weighted average market price per Ordinary Share on the ASX over the 5 ASX trading days ending on the ASX trading day before the ex rights or ex entitlement date for the pro rata issue

S is the subscription price for one Ordinary Share under the pro rata offer

D is the dividend (if any) due but not yet paid on an existing Ordinary Shares which will not be paid on the new Ordinary Shares to be issued in the pro rata issue

N is the number of Ordinary Shares that must be held on the record date for the pro rata issue to receive a right or entitlement to subscribe for one new Ordinary Share.

For the avoidance of doubt, if the formula results in no decrease in the Exercise Price then the Exercise Price remains unchanged.

d) Change in ADS Ratio. If after the Issuance Date the ADS Ratio is increased or reduced, then the number of Warrant ADSs to be provided on exercise of a Warrant will be reduced or increased (respectively) in inverse proportion to the change in the ADS Ratio Ordinary Shares per ADS and the Exercise Price per Warrant will be increased or reduced (respectively) in proportion to the change in Ordinary Shares per ADS, so that the total number or Warrant Shares underlying the Warrants and the aggregate Exercise Price for all Warrants remain unchanged.

e) Fundamental Transaction. If, at any time while this Warrant is outstanding,

10

then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share underlying the Warrant ADSs that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of capital stock of the successor or acquiring corporation or of the Company (if the Company is the surviving corporation) and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of Ordinary Shares underlying the Warrant ADSs for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one Ordinary Share in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Ordinary Shares are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction, the Company or any Successor Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of such Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant based on the Black-Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting:

(A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date,

11

(B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction,

(C) the underlying price per share used in such calculation shall be the greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (ii) the greater of (x) the last VWAP (as adjusted to a per Ordinary Share basis if the ADS to Ordinary Share ratio is greater than 1:1) immediately prior to the public announcement of such Fundamental Transaction and (y) the last VWAP (as adjusted to a per Ordinary Share basis if the ADS to Ordinary Share ratio is greater than 1:1) immediately prior to the consummation of such Fundamental Transaction, and

(D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date.

The payment of the Black Scholes Value will be made by wire transfer of immediately available funds within five Business Days of the Holder’s election (or, if later, on the effective date of the Fundamental Transaction). The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the surviving entity (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the Ordinary Shares underlying the Warrant ADSs acquirable and receivable upon exercise of this Warrant (without regard to any limitation in Section 2(e) on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the Ordinary Shares underlying the Warrant ADSs pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of

12

this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

f) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of Ordinary Shares deemed to be issued and outstanding as of a given date shall be the sum of the number of Ordinary Shares (excluding treasury shares, if any) issued and outstanding.

g) Notice to Holder.

i. Adjustment. Whenever the Exercise Price, the number of ADSs the subject of each Warrant, or the number of Warrants is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrants or the number of ADSs the subject of each Warrant and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Ordinary Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Ordinary Shares, (C) the Company shall authorize the granting to all holders of the Ordinary Shares rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Ordinary Shares, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Ordinary Shares are converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Ordinary Shares of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is

13

expected that holders of the Ordinary Shares of record shall be entitled to exchange their Ordinary Shares for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice, or such material non-public information included in such notice, with the Commission pursuant to a Current Report on Form 6-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4. Transfer of Warrant.

a) Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant ADSs without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Initial Exercise Date and shall be identical with this Warrant except as to the number of Warrant ADSs issuable pursuant thereto.

14

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

d) Transfer Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable state or foreign securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the Holder or transferee of this Warrant, as the case may be, comply with the provisions of Section 5.7 of the Purchase Agreement.

e) Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise hereof, will acquire the Warrant ADSs issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant ADSs or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

Section 5. Miscellaneous.

a) Currency. Unless otherwise indicated, all dollar amounts referred to in this Warrant are in United States Dollars (“US Dollars”). All amounts owing under this Warrant shall be paid in US Dollars. All amounts denominated in other currencies shall be converted in the US Dollar equivalent amount in accordance with the Exchange Rate on the date of calculation. “Exchange Rate” means, in relation to any amount of currency to be converted into US Dollars pursuant to this Warrant, the US Dollar exchange rate as published in the Wall Street Journal (NY edition) on the relevant date of calculation.

b) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.

c) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant ADSs, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

15

d) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

e) Authorized Shares.

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Ordinary Shares a sufficient number of shares to provide for the issuance of the Warrant ADSs and the underlying Ordinary Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant ADSs upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant ADSs and the underlying Ordinary Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the ADS or Ordinary Shares may be listed. The Company covenants that all Warrant ADSs and the underlying Ordinary Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant ADSs in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant ADSs above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant ADSs and the underlying Ordinary Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

16

Before taking any action which would result in an adjustment in the number of Warrant ADSs for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

f) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement.

g) Restrictions. The Holder acknowledges that the Warrant ADSs and the underlying Ordinary Shares acquired upon the exercise of this Warrant, if not registered and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal or foreign securities laws.

h) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

i) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

j) Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant ADSs, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any ADS or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

k) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

l) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant ADSs.

17

m) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

n) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

o) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

Benitec Biopharma Limited Announces US$2.25 Million Registered Direct Offering

New York, USA and Melbourne, Australia, September 30, 2019: Benitec Biopharma Limited (ASX:BLT; NASDAQ:BNTC; NASDAQ:BNTCW) (“Benitec” or the “Company”) today announces it has entered into a securities purchase agreement (“SPA”) with certain institutional, sophisticated and professional investors (“Investors”) to issue 2,800,000 American Depositary Shares (“ADSs”) or ADS equivalents, each ADS representing 20 ordinary shares, at a purchase price per ADS or ADS equivalent of US$0.70, and warrants to purchase 412,863 ADSs in a registered direct offering, for total gross proceeds of approximately US$2.25 million.

The ADSs (and the underlying ordinary shares) will be issued without shareholder approval under the Company’s existing placement capacity under ASX Listing Rules 7.1 and 7.1A.

In a concurrent private placement, the Company has agreed to issue purchase warrants to the Investors to purchase up to an equal amount of ADSs subscribed for by each Investor under the SPA, up to an aggregate of 3,212,863 ADSs. The issue of these purchase warrants is subject to shareholder approval. If approved by shareholders, the purchase warrants will have an exercise price of US$0.70 per ADS and will expire in five years from the date of issuance.

Benitec intends to use the net proceeds from this offering for product development and general corporate purposes. The ADSs are listed on the Nasdaq Capital Market under the symbol BNTC.

Ladenburg Thalmann & Co. Inc., a subsidiary of Ladenburg Thalmann Financial Services Inc., (NYSE American: LTS) is acting as exclusive placement agent for the registered direct offering and concurrent private placement.

The registered direct offering is expected to close on or about September 30, 2019 New York time, subject to the satisfaction of customary closing conditions. Settlement and issuance of the ADSs and ordinary shares is expected to take place on the same day.

The ADSs to be issued pursuant to the SPA represent 56,000,000 fully paid ordinary shares in the Company. The issue of the ordinary shares will fully utilise the Company’s existing placement capacity under ASX Listing Rule 7.1. The remaining shares will be issued under the Company’s placement capacity under ASX Listing Rule 7.1A. The ordinary shares issued will rank equally with other existing ordinary shares on issue.

A shelf registration statement relating to the ADSs and ADS equivalents representing ordinary shares offered in the registered direct offering described above was filed with the Securities and Exchange Commission (“SEC”) on June 1, 2017, and became effective on July 5, 2017. A final prospectus supplement and the accompanying prospectus relating to and describing the terms of the registered direct offering will be filed with the SEC. Copies of the final prospectus supplement, when available, and the accompanying prospectus relating to the registered direct offering may be obtained at the SEC’s website at www.sec.gov or from Ladenburg Thalmann & Co.
